Gastroparesis and Functional Dyspepsia: A Blurring Distinction of Pathophysiology and Treatment.

Gastroparesis and Functional Dyspepsia: A Blurring Distinction of Pathophysiology and Treatment.

J Neurogastroenterol Motil. 2018 Dec 03;:

Authors: Kim BJ, Kuo B

Abstract
Gastroparesis and functional dyspepsia are 2 of the most common gastric neuromuscular disorders. These disorders are usually confused, having both similarities and differences. The pathophysiology of these disorders involves abnormal gastric motility, visceral hypersensitivity, mucosal inflammation, and various cellular changes. Both disorders have similar symptoms such as epigastric pain or discomfort, early satiety, and bloating. If patients suspected of having either gastroparesis or functional dyspepsia present with upper gastrointestinal symptoms, they should undergo upper endoscopy to exclude an alternative organic cause. Although the gastric emptying rate is frequently assessed during the clinical workup of patients with gastroparesis or functional dyspepsia, the correlation between gastric emptying and the symptoms is generally poor. Once the diagnosis of gastroparesis or functional dyspepsia is made, treatment should focus on the predominant symptom. Recently, various treatment modalities have been developed and validated. Prokinetic agents are generally used as treatment for both gastroparesis and functional dyspepsia. Acid-suppressive therapy, Helicobacter pylori eradication, and use of drugs that enhance gastric accommodation are employed for functional dyspepsia. Psychoactive drugs are also effective in symptom control. For gastroparesis, antiemetic agents, ghrelin receptor agonists, and serotonergic agents are used aside from prokinetic agents. Acupuncture and gastric electrical stimulation can be attempted. In severe cases, endoscopic and surgical interventions are considered for symptom control.

Somatostatin receptor PET ligands - the next generation for clinical practice.

Somatostatin receptor PET ligands - the next generation for clinical practice.

Am J Nucl Med Mol Imaging. 2018;8(5):311-331

Abstract
Somatostatin receptors (SSTRs) are variably expressed by a variety of malignancies. Using radiolabeled somatostatin analogs (SSAs), the presence of SSTRs on tumor cells may be exploited for molecular imaging and for peptide receptor radionuclide therapy. 111In-DTPA-octreotide has long been the standard in SSTR scintigraphy. A major leap forward was the introduction of gallium-68 labeled SSAs for positron emission tomography (PET) offering improved sensitivity. Tracers currently in clinical use are 68Ga-DOTA-Tyr3-octreotide (68Ga-DOTATOC), 68Ga-DOTA-Tyr3-octreotate (68Ga-DOTATATE) and 68Ga-DOTA-1-NaI3-octreotide (68Ga-DOTANOC), collectively referred to as 68Ga-DOTA-peptides. 68Ga-DOTA-peptide PET has superseded 111In-DTPA-octreotide scintigraphy as the modality of choice for SSTR imaging. However, implementation of 68Ga-DOTA-peptides in routine clinical practice is often limited by practical, economical and regulatory factors related to the use of the current generation of 68Ge/68Ga generators. Centralized production and distribution is challenging due to the low production yield and relatively short half-life of gallium-68. Furthermore, gallium-68 has a relatively long positron range, compromising spatial resolution on modern PET cameras. Therefore, possibilities of using other PET radionuclides are being explored. On the other hand, new developments in SSTR PET ligands are strongly driven by the need for improved lesion targeting, especially for tumors with low SSTR expression. This may be achieved by using peptide vectors having a higher affinity for the SSTR or a broader affinity profile for the different receptor subtypes or by using compounds recognizing more binding sites, such as SSTR antagonists. This review gives an overview of recent developments leading to the next generation of clinical PET tracers for SSTR imaging.

Usefulness of positron emission mammography in the evaluation of response to neoadjuvant chemotherapy in patients with breast cancer.

Usefulness of positron emission mammography in the evaluation of response to neoadjuvant chemotherapy in patients with breast cancer.

Am J Nucl Med Mol Imaging. 2018;8(5):341-350

Abstract
Our study examines the association between two Positron Emission Mammography (PEM) semi-quantitative parameters: PUVmax (maximum uptake value) and LTB (lesion to background) baseline and the end of Neoadjuvant chemotherapy (NAC) with pathologic response in each of the following breast cancer subtype: Triple negative breast cancer (TPN), HER2-positive, and ER-positive/HER2-negative cancers. One-hundred and eight patients, 71 with invasive ductal carcinoma and 37 with infiltrating lobular carcinoma were evaluate with 18F-FDG-PEM scans before and after of NAC. We assessed the impact of 2 PEM semi-quantitative parameters for molecular subtype correlated with pathologic response according Miller-Payne grade (MPG). After NAC, an overall reduction of 2 PEM semi-quantitative parameters was found. Neither breast cancer subtypes nor Ki67 modified chemotherapy responses. Compared to PUVmax, an overall increase of LTB was found in baseline condition, independent of the expressed immunophenotype. Post-treatment values of PUVmax revealed a significant reduction compared to baseline values (4.8 ± 0.26 vs. 1.9 ± 0.18; P < 0.001) and LTB exhibited a significant decay after the first course of NAC (15.8 ± 1.36 vs. 5.5 ± 0.49; P < 0.001). Using the Kruskal-Wallis H test which showed no correlation between the different molecular subtypes and the MPG and PUVmax and LTB (P = 0.52). Two PEM semi-quantitative parameters demonstrated a statically significant correlation and equivalence across the different breast cancer subtypes correlated with pathologic response according to MPG. PEM did not allow for prediction of NAC response in terms of breast cancer biomarkers, it is not discarded that this technology might be helpful for individual treatment stratification in breast cancer.

Abstract
Positron emission tomography (PET) with prostate-specific membrane antigen (PSMA) has found widespread use for the diagnosis of biochemical recurrence of prostate cancer (PCa). Unfortunately, PET/CT is not as widely available; thus a PSMA-targeting compound for scintigraphy is of special interest. The aim of this study was to compare 99mTc-EDDA/HYNIC-iPSMA and 68Ga-PSMA-11 PET/CT qualitatively and semi-quantitatively. Twenty-three patients with metastatic PCa were underwent 99mTc-EDDA/HYNIC-iPSMA SPECT/CT followed by 68Ga-PSMA-11 PET/CT. Gleason score in all patients was obtained. Maximal standardized uptake value (SUVmax) and counts per organ, including the primary and metastatic tumor, were normalized and compared using Pearson's correlation test. Sites considered as positive have increased SUVmax and tumor-to-background ratio (TBR) in comparison with non-diseased organs/tissues (SUVmax =25.2±4.7, 18.4±1.6, 11.4±1.2 (P=0.037) from prostate, bone and lymph nodes versus TBR =35.9±45.2, 15.4±18.9, 19.1±51.7 (P=0.035) for prostate, bone and lymph nodes. 99mTc-HYNIC-iPSMA and 68Ga-PSMA-11 uptake values in the evaluation of the affected nodes were very similar, although their ranges ranged from 5-21 mm (12±7.6). Correlation coefficient was normalized between SUVmax and TBR, demonstrating r values for prostate of r2=0.731; for bone of r2=0.720; and lymph nodes of r2=0.864 (P<0.05 in all cases). Values and confidence interval at the 95% are supporting the equivalency of both parameters in primary tumor and metastases (prostate 95% CI=4.61, 4.38; bone tissue 95% CI=-2.21, 3.41 and lymph node 95% CI=4.67). We conclude that 68Ga-PSMA-11 PET/CT and 99mTc-EDDA/HYNIC-iPSMA SPECT/CT were comparable, supporting the use of 99mTc-EDDA/HYNIC-iPSMA in patients with progressive metastatic castration-resistant PCa.

Chemotherapy-induced coronary arteries calcium score deterioration as detected with unenhanced CT portion of FDG PET/CT.

Chemotherapy-induced coronary arteries calcium score deterioration as detected with unenhanced CT portion of FDG PET/CT.

Am J Nucl Med Mol Imaging. 2018;8(5):303-310

Abstract
This study aims to detect the potential impact of chemotherapy on the coronary calcium scoring (CCS) in lymphoma patients undergoing FDG-PET/CT at baseline and for therapy response using the CT portion of the exam to calculate the CCS. One hundred twelve lymphoma patients were included in the study based on having both baseline and at least 2 post-chemotherapy scans. The unenhanced CT portions of the scans were reviewed to measure the CCS which was then extracted using the Toshiba Vital Program. Agatston scores were assessed as category 1 with zero CCS unit and categories 2 to 5 having more than >1, 11, 101, and 400 CCS units respectively. For statistical analysis, paired T-Tests were used to compare results. The overall changes in total coronary artery calcium (CAC) from baseline to last treatment showed a statistically significant increase in CAC with an average increase of at least 35% in the CAC score. We also compared the overall changes in CAC with patients having category 1 and 2 Agatston at baseline and found no statistical increase in CAC post-chemotherapy. Additionally, we compared the overall changes in CAC with patients having category 3 and 4 Agatston at baseline and found statistically significant increase in CAC post-chemotherapy. In lymphoma patients, chemotherapy may cause worsening of CCS and this can serve as an early indicator of chemotherapy-induced cardiac toxicity. When present, such CCS deterioration can be detected by the unenhanced CT portion of routine oncologic FDG PET/CT scans.

Non-invasive quantification of tumor blood flow in prostate cancer using 15O-H2O PET/CT.

Non-invasive quantification of tumor blood flow in prostate cancer using 15O-H2O PET/CT.

Am J Nucl Med Mol Imaging. 2018;8(5):292-302

Abstract
Tumor blood flow (TBF) measurements in prostate cancer (PCa) provide an integrative index of tumor growth, which could be important for primary diagnosis and therapy response evaluation. 15O-water PET is the non-invasive gold standard but is technically demanding. The aim of this study was to compare the accuracy of three different non-invasive strategies with an invasively measured arterial input function (BSIF): Using image-derived input functions (IDIF) from either 1) a separate heart scan or 2) the pelvic scan or 3) a populations-based input function (PBIF). Nine patients with biopsy-verified PCa scheduled for prostatectomy were included. All patients were characterized with serum levels of PSA (s-PSA), multiparametric magnetic resonance imaging (mpMRI) and post-surgical histopathology Gleason Grade. Dynamic 15O-water was performed of the heart and the pelvic area 15 minutes apart. TBF estimated from both wash-in (K1) and wash-out (k2) constants was calculated using a one-compartmental model. Results: Mean (range) s-PSA was 12 (3-27) ng/mL, Gleason Grade Group was 2.9 (1-5), k2 was 0.44 (0.007-1.2), and K1 was 0.24 (0.07-0.55) mL/mL/min. k2 (BSIF) correlated with s-PSA (r=0.86, P<0.01) and Gleason Grade Group (rho=0.78, P=0.01). BSIF, heart-IDIF and PBIF provided near-identical k2 and K1 (r>0.95, P<0.001) with slopes near unity. The correlations of BSIF and pelvic-IDIF rate constants were good (r>0.95, P<0.001), but individual errors high. In conclusion, non-invasive protocols for 15O-water PET with IDIF or PBIF accurately measures perfusion in prostate cancer and might be useful for evaluation of tumor aggressiveness and treatment response.

A dual-labeled cRGD-based PET/optical tracer for pre-operative staging and intraoperative treatment of colorectal cancer.

Am J Nucl Med Mol Imaging. 2018;8(5):282-291

Abstract
cRGD peptides target integrins associated with angiogenesis (e.g., αvβ3) and cancer, and have been used as binding ligands for both positron emission tomography (PET) and near-infrared fluorescence (NIRF) optical imaging. This study introduces the hybrid tracer cRGD-ZW800-1-Forte-[89Zr]Zr-DFO, which is based on a novel zwitterionic fluorophore structure that reduces non-specific background uptake during molecular imaging of tumors. An in vitro binding assay was used to validate tracer performance. 10 nmol ZW800F-cRGD-Zr-DFO was injected in mice (n=7) bearing orthotopic human colorectal tumors (HT29-luc2) for tumor detection with NIRF imaging. Subsequently, ZW800F-cRGD-Zr-DFO was loaded with 89Zr and 10 nmol cRGD-ZW800-1-Forte-[89Zr]Zr-DFO (3 MBq) was injected in mice (n=8) for PET/CT imaging. Imaging and biodistribution was performed at 4 and 24 h. NIRF imaging was performed up to 168 h after administration. Sufficient fluorescent signals were measured in the tumors of mice injected with ZW800F-cRGD-Zr-DFO (emission peak ~800 nm) compared to the background. The signal remained stable for up to 7 days. The fluorescence signal of cRGD-ZW800-1-Forte-[89Zr]Zr-DFO remained intact after labeling with 89Zr. PET/CT permitted clear visualization of the colorectal tumors at 4 and 24 h. Biodistribution at 4 h showed the highest uptake of the tracer in kidneys and sufficient uptake in the tumor, remaining stable for up to 24 h. A single molecular imaging agent, ZW800F-cRGD-[89Zr]Zr-DFO, permits serial PET and NIRF imaging of colorectal tumors, with the latter permitting image-guided treatment intraoperatively. Due to its unique zwitterionic structure, the tracer is rapidly renally cleared and fluorescent background signals are low.

Therapeutic applications of adipose-derived stem cells in cardiovascular disease.

Therapeutic applications of adipose-derived stem cells in cardiovascular disease.

Am J Stem Cells. 2018;7(4):94-103

Authors: Bruun K, Schermer E, Sivendra A, Valaik E, Wise RB, Said R, Bracht JR

Abstract
Cardiovascular disease (CVD) is the number one cause of death globally, and new therapeutic techniques outside of traditional pharmaceutical and surgical interventions are currently being developed. At the forefront is stem cell-centered therapy, with adipose derived stem cells (ADSCs), an adult stem population, providing significant clinical promise. When introduced into damaged heart tissue, ADSCs promote cardiac regeneration by a variety of mechanisms including differentiation into new cardiomyocytes and secretion of paracrine factors acting on endogenous cardiac cells. We discuss the application of ADSCs, their biochemical capabilities, availability, ease of extraction, clinical trial results, and areas of concern. The multipotent capacity of ADSCs along with their ability to secrete factors promoting cell survival and regeneration, along with their immunosuppressive capacity, make them an extremely promising approach in the field of CVD therapy.

A review of clinical trials: mesenchymal stem cell transplant therapy in type 1 and type 2 diabetes mellitus.

Am J Stem Cells. 2018;7(4):82-93

Authors: Cho J, D'Antuono M, Glicksman M, Wang J, Jonklaas J

Abstract
Type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) are widely prevalent metabolic diseases with differing pathologies. T1DM manifests due to autoimmune destruction of the pancreatic beta cells, resulting in a diminished secretion of insulin. T2DM originates from a state of insulin resistance, resulting in hyperglycemia and reduction in beta cell mass. Both diseases can cause severe health consequences. Despite the globally increasing prevalence of both T1DM and T2DM there remains to be a medically defined cure for either of these diseases. Recently, mesenchymal stem cells (MSCs) have been proposed as a possible curative treatment method. In this review, we explain the molecular mechanisms underlying MSCs and their potential ability to treat T1DM and T2DM. We describe the capability of MSCs to differentiate into insulin-producing cells and regenerate pancreatic beta cells, as well as assess their role in modulating the immune system. Lastly, we evaluate the current literature focusing on the clinical application of MSC transplantation in T1DM and T2DM. Despite the favorable results, study designs and analyses cast doubt on the effectiveness of MSCs for the management of T1DM. Conversely, the positive metabolic effects consistently demonstrated in the literature offer hope for MSCs as a treatment for T2DM, at least in the short-term.

Close yet so far away: a look into the management strategies of genetic imprinting disorders.

Close yet so far away: a look into the management strategies of genetic imprinting disorders.

Am J Stem Cells. 2018;7(4):72-81

Authors: Pianka MA, McIntosh AT, Patel SD, Bakhshi PR, Jung M

Abstract
Genetic imprinting is the process of epigenetic labelling or silencing of particular genes, based on the maternal or paternal origin of the gene, in a heritable pattern. The incidence of imprinting disorders has become a growing concern due to the potential association between these congenital syndromes and assisted reproductive technologies (ARTs). This review presents a general summary of the imprinting process as well as the current knowledge surrounding the genetic and epigenetic underpinnings of the most prevalent imprinting disorders: Beckwith-Wiedemann syndrome (BWS), Silver-Russell syndrome (SRS), Prader-Willi syndrome (PWS), and Angelman syndrome (AS). As research continues to elucidate the molecular pathways that characterize genetic imprinting, efforts have been made to establish guidelines that incorporate phenotypic manifestations as well as genetic testing to ensure safe and effective management of symptoms. While these efforts are likely to benefit future clinical management, their efficacy cannot yet be generalized to all patients diagnosed with these syndromes, as many of the genetic abnormalities and the associated phenotypic manifestations have yet to be characterized. Furthermore, future advances in the knowledge of epigenetic processes and genetic loci involved in the development of these syndromes may allow for the development of curative therapies.

Correlation Between Lower Third Molar Impaction Types and Mandibular Angle and Condylar Fractures: A Retrospective Study.

Correlation Between Lower Third Molar Impaction Types and Mandibular Angle and Condylar Fractures: A Retrospective Study.

J Oral Maxillofac Surg. 2018 Sep 29;:

Authors: Samieirad S, Eshghpour M, Dashti R, Tohidi E, Javan AR, Mianbandi V

Abstract
PURPOSE: The purpose of this study was to investigate and determine the relations between mandibular third molar (M3) impaction types and mandibular angle and condylar fractures.
MATERIALS AND METHODS: A retrospective study was conducted in patients with mandibular angle and condylar fractures referred to the Oral and Maxillofacial Surgery Department of the Shahid Kamyab Hospital (Mashhad, Iran) from 2013 to 2018. Data sources were patients' hospital documents and panoramic radiographs. Predictor variables were the presence and position of impacted M3s. The Pell-Gregory classification was used to identify the horizontal and vertical positions of impaction. The impaction angulation was determined using the Schiller classification. Outcome variables were the presence of angle and condylar fractures. Data were analyzed using SPSS 16 (IBM Corp, Armonk, NY) and χ2 and Fisher exact tests.
RESULTS: The study sample consisted of 117 patients (63.2% with condylar fractures, 30.8% with angle fractures, and 6% with concomitant fractures of the condyle and angle). Most patients (88.9%) with angle fracture had impacted M3s; however, impacted M3s were absent in 59.5% of condylar fracture cases. Mesioangular and vertical positions were the most prevalent impaction angulation types in patients with mandibular angle fracture. Classes II and B were the most frequent horizontal and vertical impaction types, respectively, according to the Pell-Gregory classification. There was a statistically significant difference between fracture site and the presence or absence of impacted M3s (P < .001). Moreover, a significant relation was observed between horizontal impaction type and fracture site in patients with impacted M3s (P = .001).
CONCLUSIONS: The presence of impacted M3s increased the risk of angle fractures and simultaneously decreased the risk of condylar fractures. Fractures of the angle region were more commonly seen in patients with superficially impacted (vs deeply impacted) M3s.

Does Low-Level Laser Therapy Affect Recovery of Lingual and Inferior Alveolar Nerve Injuries?

Does Low-Level Laser Therapy Affect Recovery of Lingual and Inferior Alveolar Nerve Injuries?

J Oral Maxillofac Surg. 2018 Dec;76(12):2669-2675

Authors: Miloro M, Criddle TR

Abstract
PURPOSE: Iatrogenic damage to the inferior alveolar nerve (IAN) and lingual nerve (LN) may occur during routine oral and maxillofacial surgery procedures. The primary aim of this study was to determine, using a prospective, double-blind, randomized controlled clinical trial, whether the proportion of nerve-injured patients with postoperative neurosensory improvement over a 3-month period differed significantly between a control group and a low-level laser therapy (LLLT) group.
PATIENTS AND METHODS: The study sample consisted of 35 patients with iatrogenic nerve injury due to third molar odontectomy, dental implant placement, or local anesthetic injection. The investigators used a randomized, double-blind laser delivery system to administer either placebo or LLLT to patients who met the inclusion criteria. The outcome variable of neurosensory improvement was defined as a minimum 1-unit increase from baseline in visual analog scale rating and was based on standard objective clinical neurosensory testing. Study variables included the affected nerve (IAN or LN) and time from injury to treatment (3 to 12 months or >12 months). Univariate statistical analysis (χ2 test) was performed to determine significance between the groups.
RESULTS: Neurosensory improvement was observed in 46.7% of the LLLT patients, who showed at least a 1-unit improvement at 3 months, compared with 38.5% improvement for controls (P = .66), regardless of the specific nerve involved (IAN or LN). In addition, no observed difference was noted between the study groups based on time from injury to treatment.
CONCLUSIONS: This study failed to provide sufficient evidence to conclude that a difference in neurosensory improvement exists between the LLLT and placebo groups with IAN or LN injuries. However, this study is unique in the prospective double-blind study design and comprehensive neurosensory testing protocols. There is a continued need for further clinical studies on LLLT in oral and maxillofacial surgery nerve injuries.

Dynamic Stability Assessment of the Temporomandibular Joint as a Sequela of Open Reduction and Internal Fixation of Unilateral Condylar Fracture.

Dynamic Stability Assessment of the Temporomandibular Joint as a Sequela of Open Reduction and Internal Fixation of Unilateral Condylar Fracture.

J Oral Maxillofac Surg. 2018 Dec;76(12):2598-2609

Authors: Kuntamukkula S, Sinha R, Tiwari PK, Paul D

Abstract
PURPOSE: Dynamic stability of the temporomandibular joint (TMJ) is the characteristic of the joint to achieve normal function by harmonious, balanced, synchronized interactions of the various functional subunits of the stomatognathic system. The aim of this study was to evaluate changes in the mechanics and dynamics of the TMJ during recovery from surgical treatment of an isolated condylar fracture.
PATIENTS AND METHODS: This is a prospective cohort study involving 30 patients who underwent open reduction and internal fixation for an isolated unilateral condylar fracture and were clinically asymptomatic at 6 months after surgery. The dynamics of the TMJ were assessed by bite-force analysis, both static and dynamic, to assess masticatory efficiency. Surface electromyography was recorded to assess changes in muscle dynamics. Joint vibration analysis was performed to evaluate the internal functioning of the TMJ. All the assessments were carried out bilaterally to allow comparison of the injured and uninjured joints, and the data were analyzed with the paired t test and independent-samples t test. Statistical significance was considered at P < .05.
RESULTS: The study included 18 male and 12 female patients aged between 20 and 40 years. Bite-force analyses showed significantly higher bite forces on the uninjured side at 6 months after surgery. Similarly, surface electromyography analysis showed increased muscle activity on the affected side pointing toward some compensatory hyperactivity in the masticatory muscles. Joint vibration analysis showed that there was increased friction during function in both the injured and uninjured joints.
CONCLUSIONS: The observations in this study suggest that residual imbalances are present in the TMJ at 6 months after open reduction and internal fixation of condylar fractures. Therefore, long-term studies are required to establish a complete timeline of adaptive changes occurring in the TMJ after condylar fractures, especially in comparison with other treatment modalities.

Role of Non-Albicans Candida and Candida Albicans in Oral Squamous Cell Cancer Patients.

J Oral Maxillofac Surg. 2018 Dec;76(12):2564-2571

Authors: Mäkinen A, Nawaz A, Mäkitie A, Meurman JH

Abstract
PURPOSE: This study examined the prevalence of Candida species in the saliva of oral squamous cell carcinoma patients and its effect on the mortality rate.
MATERIALS AND METHODS: One hundred patients with oral cavity squamous cell carcinoma undergoing protocol treatment at Helsinki University Hospital were recruited into the study from March 2011 through 2014. For comparison, 75 age-matched controls with no current or previously treated oral cancer were recruited. Paraffin-stimulated whole saliva samples were collected and cultivated on CHROMagar Candida medium (CHROMagar, Paris, France) to establish possible Candida growth. The API ID 32C yeast identification kit (bioMérieux, Lyon, France) and Bichro-Dubli Fumouze latex agglutination test (Fumouze Diagnostics, Levallois-Perret, France) were used for further identification of different Candida species. Patients' medical records were studied for information on their health habits and general health status, as well as tumor-related data. The patients' status regarding being alive and cancer free was checked at a follow-up point in December 2017. Descriptive statistics and cross tabulation were carried out, and the P value was set at .05.
RESULTS: Candida species were detected in 74% of the oral cancer patients' samples, with C. albicans being the most common species (84%). Other species identified were C. dubliniensis (8%), C. tropicalis (4%), C. glabrata (3%), C. parapsilosis (3%), C. sake (3%), C. krusei (1%), and C. guilliermondii (1%). After the follow-up period, 63% of the patients were alive and 86% of them were cancer free. Harboring Candida species in the saliva was not associated with any increase in the mortality rate.
CONCLUSIONS: C. albicans was common in the oral cavity of the oral squamous cell carcinoma patients. However, in this patient population, we did not observe a statistically significant effect of the yeast on the mortality rate.

Acute and Chronic Suppurative Osteomyelitis of the Jaws: A 10-Year Review and Assessment of Treatment Outcome.

Acute and Chronic Suppurative Osteomyelitis of the Jaws: A 10-Year Review and Assessment of Treatment Outcome.

J Oral Maxillofac Surg. 2018 Dec;76(12):2551-2558

Authors: Haeffs TH, Scott CA, Campbell TH, Chen Y, August M

Abstract
PURPOSE: To review cases of suppurative osteomyelitis of the jaws treated at the Massachusetts General Hospital (Boston, MA) over a 10-year period, evaluate specifics of disease presentation, and answer the clinical question: are there identifiable variables associated with treatment outcome?
MATERIALS AND METHODS: A retrospective cohort study was completed using patients treated for suppurative osteomyelitis of the jaws at the Massachusetts General Hospital from April 2006 to October 2016. Inclusion criteria were a diagnosis of suppurative osteomyelitis of the jaw, age older than 18 years, and complete medical records. Patients with nonsuppurative disease, radiation history, or antiresorptive exposure were excluded. Candidate variables included demographic information, medical and dental history, presenting signs and symptoms, and radiologic and laboratory findings. The outcome variable was successful treatment, defined as resolution of symptoms and radiographic evidence of healing after initial treatment. Appropriate statistical analyses were performed with significance set a P value less than .05.
RESULTS: Forty-two patients met the inclusion criteria. Mean age was 53 years (range, 20 to 80 yr) and 26 were women (62%). Common comorbidities included cardiovascular disease (52%), tobacco use (45%), and psychiatric disorders (45%). Pain (90%), swelling (86%), and neurosensory change (50%) were the most common findings. Common microbacterial isolates included Streptococcus milleri (74%) and coagulase-negative Staphylococcus species (43%), which showed marked antibiotic resistance. Surgical debridement was the most common intervention (93%). Successful treatment was found in 86%. Of 6 persistent cases, 4 resolved with a second debridement and continued antibiotics and 2 required resection. Increased white blood cell (WBC) count at presentation (P = .005) and associated psychiatric diagnoses (P = .037) were statistically associated with unsuccessful initial treatment.
CONCLUSION: The results of this study indicate that antibiotic resistance is commonly encountered in this patient population, although it was not associated with unsuccessful outcome. Patients presenting with increased WBC count and concurrent psychiatric comorbidities required protracted treatment.

Opioid Abuse and Dependence in Those Hospitalized Due to Head and Neck Cancer.

Opioid Abuse and Dependence in Those Hospitalized Due to Head and Neck Cancer.

J Oral Maxillofac Surg. 2018 Dec;76(12):2525-2531

Authors: Nalliah RP, Shroff D, Stein K, Chandrasekaran S, Rampa S, Allareddy V, Allareddy V

Abstract
PURPOSE: In the United States, 2.1 million people develop substance abuse disorders that are associated with prescribed opioids. The objective of the present study was to identify the factors associated with opioid abuse and dependence (OAD) in those hospitalized for head and neck cancer (HNC). Although measures are being implementing to reduce opioid prescribing, the use of these drugs in individuals with HNC can be valuable. However, little is known about OAD among this cohort of individuals.
MATERIALS AND METHODS: The present study was a retrospective analysis of the Nationwide Inpatient Sample for 2012 to 2014. All patients hospitalized because of any HNC were selected. The OAD prevalence was identified. The patient demographic, hospital, and geographic factors were considered independent variables and OAD was the outcome. Multivariable logistic regression model was used to identify the factors associated with OAD.
RESULTS: A total of 92,055 patients were hospitalized because of HNCs. OAD was prevalent in 0.8% of the patients. The OAD rates were greatest in patients with a malignant neoplasm of ill-defined sites within the lip, oral cavity, and pharynx (1.6%). Age 30 to 44 years (odds ratio [OR] 5.19, 95% confidence interval [CI] 2.23 to 12.06; P < .01) and age 45 to 64 years (OR 4.05, 95% CI 2.15 to 7.61; P < .01) were associated with greater odds for OAD compared with age older than 64 years. Black (OR 1.76, 95% CI 1.12 to 2.78; P = .01) and Hispanic (OR 2.20, 95% CI 1.27 to 3.79; P < .01) race/ethnicity were associated with greater odds for OAD compared with white race/ethnicity. Individuals covered by Medicaid (OR 2.08, 95% CI 1.26 to 3.43; P < .01), and those who were uninsured (OR 2.27, 95% CI 1.05 to 4.89; P = .04) were associated with greater odds for OAD compared with those covered by private insurance. An increase in the comorbid burden was associated with increased odds of OAD (OR 1.57, 95% CI 1.47 to 1.68; P < .001).
CONCLUSIONS: The present study identified specific anatomic sites where malignant neoplasm was associated with greater odds of OAD. Additionally, the study found that coverage by Medicaid, black and/or Hispanic race/ethnicity, lowest income households, and a greater comorbid burden were associated with greater odds of OAD.

Direction-Changing and Direction-Fixed Positional Nystagmus in Patients With Vestibular Neuritis and Meniere Disease.

Direction-Changing and Direction-Fixed Positional Nystagmus in Patients With Vestibular Neuritis and Meniere Disease.

Clin Exp Otorhinolaryngol. 2018 Dec 05;:

Authors: Kim CH, Shin JE, Yoo MH, Park HJ

Abstract
Objectives: Direction-changing positional nystagmus (PN) was considered to indicate the presence of benign paroxysmal positional vertigo involving lateral semicircular canal in most cases. We investigated the incidence of PN on the supine head-roll test and compared the characteristics of nystagmus in patients with vestibular neuritis (VN) and Meniere disease (MD).
Methods: A retrospective review of patients, who were diagnosed with unilateral VN or unilateral definite MD between September 2005 and November 2011, was conducted. Sixty-five VN patients and 65 MD patients were enrolled. Eye movements were recorded for 30-60 seconds at the positions of sitting, head roll to the right, and head roll to the left, and maximum slow-phase eye velocity was calculated. PN was classified as direction-fixed (paretic or recovery) and direction-changing (geotropic or apogeotropic).
Results: Spontaneous nystagmus was observed in 57 patients (87%, the slow-phase eye velocity of 7°/sec±5°/sec) with acute VN, 39 (60%, 2°/sec±1°/sec) with follow-up VN, and 32 (49%, 2°/sec±2°/sec) with MD. Direction-fixed PN was the most common type. Direction-fixed paretic type was most common in acute VN (80%) and follow-up VN (42%), and direction-fixed recovery type was most common in MD (31%). Paretic type was significantly more common in acute VN (80%) than in follow-up VN (42%) and MD (26%), and the recovery type was significantly more common in MD (31%) than in acute VN (3%) and follow-up VN (14%). Direction-changing PN was more common in MD (22%), followed by follow-up VN (14%) and acute VN (9%).
Conclusion: Though direction-fixed paretic PN was most common in VN and MD patients, direction-changing PN could be observed in a few patients (9%-20%) with peripheral vestibular disorders regardless of the duration from the onset of dizziness, suggesting the presence of otolith-related dizziness.

Abstract
BACKGROUND: Skin tumors surgery is common and well established. There is discrepancy between recommendations on macroscopic margins to apply and therapeutic decisions taken on histological margins. The purpose of this study is to examine skin shrinkage upon exeresis, then in formalin, to understand the anatomo-clinical discrepancy, which is often found.
MATERIAL AND METHODS: It was a prospective study, lasting a month, including patients receiving skin surgery. For each tumor, the surgeon carried out 4 margins measurements before and after exeresis ; margins measured again in histology. The evaluation criterion was the difference between preoperative, postoperative and histological margins measurement. These data was weighting according to factors linked to the patient and the tumor.
RESULTS: Seventy-nine tumors for 61 patients had been studied. The study showed a significant shrinkage between preoperative measurements and postoperative, from 0.4 to 0.6mm. It is correlated with no one tested factors. Significant shrinkage between 0.4 and 0.5mm was also established between preoperative and histological measurements. However, there is a significant augmentation between postoperative and histological measurements.
CONCLUSION: This last result could be linked to the inflammatory peri-wound skin that surgeon consider as tumoral process so exclude of his margin, while histology could show a healthy area. In front of these results, an expert committee leading a more important study could include histological margins recommendations to the actual clinical recommendations.

[Congenital auricular anomalies: Early non-surgical correction by splinting].

Ann Chir Plast Esthet. 2018 Nov 30;:

Authors: Vincent PL, Voulliaume D, Coudert A, Truy E, Ayari-Khalfallah S

Abstract
OBJECTIVES: Auricular deformities therapy by external molding is possible. It must be undertaken early, ideally before the sixth week of life. Persistency of maternal hormones impregnation during the first six weeks of life permits to maintain the malleable cartilages. They can thus be molded into a new position. After the end of this hormonal therapy, the cartilages gradually become rigid in a specific position.
MATERIAL AND METHODS: All infants under 6 weeks of age with isolated auricular deformities between July 2015 and July 2016 received a neonatal treatment with an external molding device called EarWell© or a custom-made one with silicone. The device was removed when the infant was 6 weeks old and had a treatment duration of at least 4 weeks. A 6 months minimum follow-up was carried out to evaluate the result.
RESULTS: From July 2015 to July 2016, 42 deformed ears were treated in 38 newborns. The average age to apply the device was 2 weeks of life with a treatment duration of 5 weeks. The immediate outcome was evaluated as excellent by the parents in 81% of cases, with an ear judged as "normal" and as excellent by the surgeon in 75% of cases. There were no major complications.
CONCLUSIONS: External molding therapy for infants with ear deformities has proved to be effective in 75 to 81% of cases. It is a non-invasive treatment that avoids subsequent surgical treatment for the majority of patients.

Biomark Med. 2018 Dec 04;:1291-1302

Authors: Mao YM, Zhao CN, Liu LN, Wu Q, Dan YL, Wang DG, Pan HF

Abstract
AIM: We performed this meta-analysis in order to evaluate circulating interleukin-8 (IL-8) levels in systemic lupus erythematosus (SLE) patients more accurately and explore its related influencing factors.
METHODS: The related literature was systematically searched in PubMed, Embase and The Cochrane Library database (up to 28 March 2018). All data analysis was performed by Stata 12.0 software.
RESULTS: The results showed SLE patients had a higher circulating IL-8 levels than normal controls (pooled standardized mean difference = 0.963; 95% CI: 0.416-1.511). Subgroup analyses indicated SLE patients with age <40 years, Asia group and disease duration <10 years had higher IL-8 levels.
CONCLUSION: Compared with normal controls, circulating IL-8 levels in SLE patients are elevated and affected by age, region and disease duration.

Abstract
AIM: The NGAL is a biomarker of renal injury associated with the progression of heart failure (HF). We examine the association of NGAL with Galectin-3 in patients with chronic HF.
METHODS: We consecutively enrolled 115 subjects with stable ischemic HF of reduced ejection fraction. Serum levels of Galectin-3, b-type natriuretic peptide and NGAL were measured.
RESULTS: NGAL levels were positively correlated with Galectin-3 (rho = 0.26; p = 0.04) and b-type natriuretic peptide levels (rho = 0.30; p = 0.005) and inversely correlated with ejection fraction (rho = -0.31; p = 0.02) and creatinine clearance levels. The NGAL was independently associated with Galectin-3 levels.
CONCLUSION: A positive correlation between NGAL and Galectin-3 in HF patients was found, revealing a potential association between renal injury and myocardial fibrosis and remodeling in HF.

Therapeutic potential of trametinib to inhibit the mutagenesis by inactivating the protein kinase pathway in non-small cell lung cancer.

Therapeutic potential of trametinib to inhibit the mutagenesis by inactivating the protein kinase pathway in non-small cell lung cancer.

Expert Rev Anticancer Ther. 2018 Dec 04;:1-7

Authors: Jeanson A, Boyer A, Greillier L, Tomasini P, Barlesi F

Abstract
INTRODUCTION: Mitogen-activated protein kinase (MAPK) pathway is known to be involved in the tumorigenesis of cancer cells including non-small cell lung cancer (NSCLC) and kinases involved in this pathway are frequently mutated. The development of new targeted therapies in cancer has led to the evaluation of MEK-inhibitors. Areas covered: This article reviews different studies using trametinib alone, in combination with other targeted therapies or associated with other non-targeted therapies in NSCLC, with a focus on KRAS mutant and BRAF mutant NSCLC. Expert commentary: Trametinib demonstrated activity in association with a BRAF inhibitor when BRAF was mutated. The combination of trametinib and dabrafenib has been approved for this population of BRAF mutant NSCLC patients. For KRAS mutant NSCLC, the combination of trametinib with chemotherapy has showed promising results and should be further assessed. Several clinical trials are ongoing, assessing trametinib in combination with other targeted therapies. In addition, preclinical studies suggest a synergistic effect of trametinib in combination with immune checkpoint inhibitors and such combinations should be studied in clinical trials.

Authors: Saltarelli R, Palma F, Gioacchini AM, Calcabrini C, Mancini U, De Bellis R, Stocchi V, Potenza L

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE: Ganoderma lucidum (Curtis) P. Karst. (also known as Linghzhi and Reishi) is the most appreciated and revered medicinal mushroom across many Asian countries, but its properties have also attracted interest in Western countries. Indeed, in the West, it is now commercially available as a dietary supplement in preparations mainly made from spores, fruiting bodies and mycelia. It is employed in both nutraceutical and pharmacological formulations either for its immuno-modulating anti-inflammatory properties or as an effective adjuvant therapy in the treatment of several chronic diseases as well as in cancer treatment.
AIM OF THE STUDY: The aim of this investigation was to show the phytochemical composition and antioxidant and antiproliferative activities of an ethanolic extract from an Italian mycelial isolate of Ganoderma lucidum and to assess its effects on nuclear DNA.
MATERIALS AND METHODS: LC/ESI-MS and tandem mass spectrometry MSMS were used to obtain structural identification of ethanolic G. lucidum extract constituents. Antioxidant activities were determined by the DPPH method, chelating effect on Fe2+ and lipoxygenase inhibition while cytotoxic activities using the MTT assay. Effects on nuclear DNA were evaluated using the DNA nicking assay in a cell-free system and the fast halo assay performed on oxidatively injured human U937 cells; apoptosis induction was investigated using the non-denaturing fast halo assay and DNA laddering detection.
RESULTS: This extract was rich in several bioactive compounds, mainly phenolic and triterpenic acids. It showed antioxidant activity and protective effects in oxidatively injured DNA in cell-free analyses and antiproliferative, genotoxic, and proapoptotic effects in the cell model.
CONCLUSIONS: Italian G. lucidum mycelium isolate appears to be a source of various natural compounds that may have applications as chemopreventive agents or functional foods.

Abstract
PURPOSE: To determine if treatment of nasopharyngeal carcinoma (NPC) induces early changes in amide proton transfer-weighted (APTw) magnetic resonance imaging (MRI), and to perform a preliminary evaluation of APTw imaging in response assessment.
METHODS: Sixteen patients with NPC planned for treatment with radiotherapy and/or chemotherapy underwent APTw imaging of the primary tumour pre-treatment and 2-week intra-treatment. Difference in pre- and intra-treatment APT mean (APTmean) was compared using the Wilcoxon signed rank test. Differences in APTmean and percentage change (%Δ) in APTmean were compared between responders and non-responders based on the outcome at 6 months, using the Mann-Whitney U test.
RESULTS: APTmean decreased in 9/16 (56.3%) and increased in 7/16 (43.7%) with no significant difference between the pre- and intra-treatment APT values for the whole group (p > 0.05). NPC showed response in 11/16 (68.8%) and non-response in 5/11 (31.2%). There were significant differences between the %Δ of responders and non-responders for APTmean (p = 0.01). Responders showed %Δ decrease in APTmean of - 23.12% while non-responders showed a %Δ increase in APTmean of + 102.28%.
CONCLUSION: APT value changes can be detected in early intra-treatment. Intra-treatment %Δ APTmean shows potential in predicting short-term outcome.

Predictive factors of patients' general quality of life after nasal septoplasty.

Predictive factors of patients' general quality of life after nasal septoplasty.

Eur Arch Otorhinolaryngol. 2018 Dec 03;:

Authors: Valsamidis K, Titelis K, Karkos P, Markou K, Constantinidis J, Triaridis S

Abstract
PURPOSE: Although septoplasty is considered to be the definitive treatment of septal deviation and is associated with an increase of nasal patency, patients are not always satisfied with the surgical outcome as assessed by its effect on their general Quality of Life (QOL).The aim of this study was to identify the predictive factors that influence the patients' QOL after surgery.
METHODS: 60 patients with nasal obstruction and septal deviation were enrolled in this prospective study, and they all completed the follow-up survey of 6 postoperative months. Symptom severity (Nasal Obstruction Symptom Evaluation-NOSE, Sino nasal outcome test 22-SNOT-22), sleep quality (Epworth Sleepiness Scale-ESS), olfactory function (Threshold Discrimination Identification-TDI score), voice quality (Nasalance score and Voice Handicap Index-VHI), stress (SQ test) and emotional status (Beck Depression Index-BDI) were evaluated as predictive factors of patients' QOL (Glasgow Benefit Inventory-GBI) postoperatively. We also analyzed age, gender, smoking, socioeconomic status, type of septal deviation and changes of nasal patency (with the use of rhinomanometry, acoustic rhinometry, and peak nasal inspiratory flow).
RESULTS: From all the analyzed parameters, the nasal obstruction symptom severity, the sleep quality, and stress levels were only significantly associated with patients' overall QOL (p < 0.05; univariate analysis). However, on multiple regression, positive changes in NOSE score (OR 15.09, 95% CI 1.47-22.64, p < 0.05) and SQ test (OR 4, 95% CI 1.12-14.3, p < 0.05) were only related with higher likelihood of participants' QOL improvement after surgery.
CONCLUSIONS: Thorough preoperative evaluation of the symptom severity and stress levels is critical as these two factors are predictive of patient's satisfaction after septoplasty.

Authors: Choi HG, Lee JK, Kong IG, Lim H, Kim SY

Abstract
INTRODUCTION: The previous studies suggested an association between osteoporosis and sudden sensory neural hearing loss (SSNHL). The aim of the present study was to evaluate the association between osteoporosis and benign paroxysmal positional vertigo (BPPV).
MATERIALS AND METHODS: Data from the Korean National Health Insurance Service-National Sample Cohort of participants who were ≥ 50 years old were collected from 2002 to 2013. A total of 13,484 BPPV participants were matched with respect to age group, sex, income group, region of residence, hypertension, diabetes, and dyslipidemia to 53,936 controls. In both the BPPV and control groups, the previous histories of osteoporosis were evaluated. Crude (simple) and adjusted odds ratios (ORs) of osteoporosis for BPPV were analyzed using unconditional logistic regression analyses. Subgroup analyses were conducted according to age, sex, and BPPV frequency.
RESULTS: A total of 18.64% (2514/13,464) of the BPPV group and 12.21% (6589/53,936) of the control group had a history of osteoporosis (P < 0.001). The adjusted OR of osteoporosis for BPPV was 1.29 (95% CI = 1.23-1.35, P < 0.001). In the subgroup analysis according to age and sex, the ≥ 70-year-old men did not demonstrate a high adjusted OR of osteoporosis for BPPV. All other age and sex subgroups demonstrated high adjusted ORs of osteoporosis for BPPV.
CONCLUSIONS: Osteoporosis increased the risk of BPPV in the population aged ≥ 50 years. The OR of osteoporosis was higher in the frequent BPPV group than in the less frequent BPPV group.

Authors: Lin G, Chen Q, Huang J, Chen L, Lin T, Lin Q

Abstract
PURPOSE: Obstructive sleep apnea (OSA) is related to endothelin-1 (ET-1). Continuous positive airway pressure (CPAP) is an effective therapy for OSA. However, the effectiveness of CPAP on ET-1 levels in patients with OSA yielded contradictory results. We conducted a meta-analysis to assess the effect of CPAP on ET-1 levels in OSA.
METHODS: The Embase, and Cochrane Library and PubMed were searched before March, 2018. The overall effects were measured by the standardized mean difference (SMD) with a 95% confidence interval (CI). Ten studies were included and the meta-analysis was conducted using Stata 14.0.
RESULTS: 10 studies involving 375 patients were included in the meta-analysis. The result showed that there was a significant reduction in ET-1 levels in OSA patients before and after CPAP therapy (SMD = - 0.74, 95% CI = - 1.30 to - 0.17, z = 2.56, p = 0.01). Further, subgroup analysis demonstrated that Apnea-Hypopnea Index (AHI), CPAP therapy duration, and sample size also affected CPAP therapy.
CONCLUSIONS: Our meta-analysis indicated that CPAP treatment among OSA patients was significantly was related to a decrease in ET-1 levels. Further prospective long-term studies with a larger number of patients are needed to evaluate and clarify this issue.

Authors: Matsumine H, Kamei W, Fujii K, Shimizu M, Osada A, Sakurai H

Abstract
The authors developed a one-stage double-muscle reconstruction technique for facial paralysis using a latissimus dorsi (LD) flap and a serratus anterior (SA) flap, which were dually reinnervated by the contralateral facial nerve (FN) and ipsilateral masseter nerve (MN). The procedure was performed for 61-year-old man 3-years after resection of a malignant tumor and a 24-year-old woman 10-years after temporal fracture with facial paralysis. A double-muscle flap comprising left LD and SA flaps was harvested, a 15-cm thoracodorsal nerve (TN) section was attached to the LD flap, and 5-cm and 1-cm sections of the long thoracic nerve (LTN) were attached to the proximal and distal sides of SA flap. The LD flap and SA flap were sutured along the direction of motion of the zygomaticus major and risorius muscles, respectively. The contralateral FN and ipsilateral MN were interconnected by nerve suturing: the medial branch of TN to the distal end of LTN, the proximal end of LTN to the ipsilateral MN, and the buccal branch of contralateral FN to the main trunk of TN. After surgery, good contraction of the transferred flaps resulted in reanimation of a natural symmetrical smile; no complications were observed during the 12-month follow-up period.

Is the LICOX® PtO2 system reliable for monitoring of free flaps? Comparison between two cohorts of patients.

Microsurgery. 2018 Dec 04;:

Authors: Arnež ZM, Ramella V, Papa G, Novati FC, Manca E, Leuzzi S, Stocco C

Abstract
BACKGROUND: Licox® PtO2 is a minimally invasive monitoring system for continuous measurement of tissue oxygen tension in all types of free tissue transfers. Our study compares two consecutive series of patients undergoing microsurgical reconstruction monitored with standard clinical bedside surveillance and with the Licox® PtO2 system regarding flap loss and flap salvage, the sensitivity, specificity, and cost-effectiveness.
METHODS: We performed a longitudinal observational prospective study of all patients undergoing microsurgical reconstructions between 2016 and 2017. Group 1 included 43 patients that underwent standard clinical bedside postoperative flap monitoring whereas group 2 included 44 consecutive patients also monitored with Licox® PtO2 system. Flap complications such as return to theater for vascular compromise, partial and total flap loss and flap salvage rate were analyzed.
RESULTS: We recorded no significant difference between the two groups regarding the rate of vascular complications (P = .31), return to the theater (P = .31), flap salvage (P = .9), partial and total flap loss (P = .36 and P = .49, respectively). When analyzing the Licox® PtO2 system monitoring group, we documented six false-positive results (13.6%) and 0 false negatives with an accuracy of 0.86, a sensibility of 1.00, and a specificity of 0.85.
CONCLUSIONS: This is the first study that provides statistical data about the comparison of postoperative free flap monitoring by standard clinical bedside method and Licox® PtO2 system. For the monitoring of buried flaps, the Licox® PtO2 monitoring can be used only as a supplement to other systems. Its use, compared to near-infrared spectroscopy or clinical bedside monitoring, was not found cost-efficient.

Authors: Siemionow M, Cwykiel J, Uygur S, Kwiecien G, Oztürk C, Szopinski J, Madajka M

Abstract
BACKGROUND: Due to limited number of studies, we tested feasibility of autologous epineural sheath conduit (ESC) in repair of 6-cm median nerve gaps in a sheep-the large animal model.
MATERIALS AND METHODS: Eight ewes, 6-8 months old, 30-35 kg, were divided into three experimental groups: group 1-no defect repair (n = 4 nerves/group), group 2-autograft controls (n = 6 nerves/group), group 3-autologous ESC filled with saline (n = 6 nerves/group). ESC was constructed from a 6-cm long segment of sheep median nerve and tested for expression of laminin B, Glial fibrillary acidic protein (GFAP), S-100 and CD31 using immunofluorescent staining. At 6 months after nerve repair, nerve conduction velocity and somatosensory evoked potentials (SSEP) assessed neurosensory recovery, while histomorphometry tested nerve regeneration.
RESULTS: Ex vivo characterization of ESC, before in vivo nerve gap repair, showed high laminin B expression, which supports axonal growth. At 6 months post-repair, structural integrity of ESC was preserved. ESC was well-vascularized and tissue adhesions were comparable to autograft controls. The maximal conduction velocities (29.80 ± 5.85 ms vs. 32.28 ± 6.75 ms; p = .44), action potential amplitudes (32.68 ± 17.44 mV vs. 44.14 ± 23.10 mV; p = .38) and SSEP amplitude values (6.18 ± 5.84 mV vs. 4.68 ± 2.53 mV; p = .28) were comparable between autograft and ESC groups. Presence of regenerating axons was confirmed in the distal segment of ESC at 6 months after repair.
CONCLUSION: The feasibility of ESC in restoration of 6-cm long nerve defects in a sheep median nerve model was confirmed by nerve conduction assessments and correlated with axonal regeneration tested by histomorphometry. We confirmed ESC potential in support of regeneration of long nerve defects.

Foreign bodies in the ear, nose, and throat in Japan: association with sociocultural and geographical conditions.

Foreign bodies in the ear, nose, and throat in Japan: association with sociocultural and geographical conditions.

Auris Nasus Larynx. 2018 Nov 30;:

Authors: Oya R, Horii A, Uno A, Kawasaki Y, Inohara H

Abstract
OBJECTIVE: Foreign bodies (FBs) in ear, nose, and throat (ENT) are common ENT emergencies but are sometimes life-threatening. However, FBs could be avoidable by the efficient announcement about the risk of these occurrence to the public. Fish bones are commonly found as throat FBs, and small toys are commonly found as pediatric ear and nose FBs. We hypothesized that there were relationships between the occurrence of FBs and sociocultural/geographical conditions. The purpose of this study is to clarify the risk factors of FBs in ENT regions related to eating customs and weather conditions.
METHODS: From April 2009 to March 2014, 94,479 patients visited the Chuo Emergency Clinic (CEC) in Osaka, which is a local emergency center for Osaka prefecture in Japan. Among them, 3229 patients with throat FBs, 577 children (0-15 years of age) with ear FBs, and 1999 children (0-15 years of age) with nose FBs were enrolled into the present study. Monthly trends in the number of throat FBs were examined in relation to fish eating customs. The monthly average of the daily ratio of pediatric patients with ear or nose FBs to the total number of patients were examined in relation to weather parameters using a database of the Japan Meteorological Agency.
RESULTS: The incidence of throat FBs was significantly higher in July and January (p<0.05, analyzed by ANOVA and Tukey-Kramer test), presumably because Japanese people have more chances to eat fish in these months due to the traditional fish-eating customs. There was also a significant correlation between the number of pediatric patients with ear and nose FBs and the bad weather parameters including daily rainfall (r=0.76, p=0.0043; r=0.57, p=0.050, respectively, analyzed by the Pearson product-moment correlation coefficient). This is because children would spend longer time inside on rainy days, which increases the chance of putting a small toy part in the ear and nose.
CONCLUSIONS: FBs in throat and ear/nose occurred more frequently in the specific periods to eat fish and rainy days, respectively. Therefore, public announcement on the risk of occurrence of FBs based on sociocultural and geographical data is helpful to prevent FBs.

EFFECT OF FLAMINGO EXERCISES ON BALANCE IN PATIENTS WITH BALANCE IMPAIRMENT DUE TO SENILE OSTEOARTHRITIS.

Arch Gerontol Geriatr. 2018 Oct 29;81:48-52

Authors: Uzunkulaoğlu A, Yıldırım İB, Güneş Aytekin M, Ay S

Abstract
OBJECTIVE: To investigate the effect of flamingo exercise with or without KAT 2000 device on the balance problems due to senile OA.
PARTICIPANTS: Ninety elderly osteoarthritic patients with balance impairment.
INTERVENTIONS: Participants were randomly assigned into three groups; Kinesthetic ability trainer (KAT 2000) training group (Group 1) (n = 30), Flamingo training group (Group 2) (n = 30), Combined training group (Group 3) (n = 30) group. 45 minutes individualized training sessions as three times a week for 4 weeks were given to all participants.
MAIN OUTCOME MEASURES: Patients were evaluated with Berg balance scale (BBS), kinesthetic ability trainer (KAT 2000) static and dynamic scores, timed up and go test (TUGT), walking speed (WS), Activities Specific Balance Confidence (ABC) Scale and Functional Reach Test (FRT) at the baseline and at the end of 4 weeks.
RESULTS: At the end of the therapy, there were statistically significant improvements in KAT 2000 static and dynamic scores, TUGT scores, WS and ABC Scale in all groups (p < 0.05). At the end of the therapy there were statistically significant differences in Group 3 for KAT 2000 static and dynamic scores, TUGT scores, WS and ABC Scale than the other groups (p < 0.05). But there were no statistical difference in BBS and FRT score between the groups (p > 0.05).
CONCLUSIONS: Both flamingo and KAT2000 exercises device have positive effects on the balance problems due to senile OA. Combined with the KAT2000 device, the effects of flamingo exercises on balance disorder in senile osteoarthritis patients are more pronounced.

Patterns of aged care use among older Australian women: A prospective cohort study using linked data.

Arch Gerontol Geriatr. 2018 Nov 19;81:39-47

Authors: Rahman M, Efird JT, Byles JE

Abstract
BACKGROUND: Women live longer than men and have an increased need for long-term care. The objective of this study was to identify patterns of aged care use among older Australian women and to examine how these patterns were associated with their demographic and health-related characteristics.
METHODS: The sample consisted of 8768 women from the 1921-1926 birth cohort of the Australian Longitudinal Study on Women's Health (ALSWH), who had survived to age 75-80 years. ALSWH survey and linked administrative aged care and death datasets from 2001 to 2011 were utilized. Patterns of aged care use were identified using a repeated measure latent class analysis.
RESULTS: We identified four patterns of aged care use over time, differentiated by timing of service onset, types of service use and time of death. Approximately 41% of the sample were non-users or using basic home and community care (HACC), while 24% were at high risk of using moderate to high-level HACC/community aged care package (CACP). Only 11% had a greater risk of using residential aged care (RAC) over time. Being widowed, residing in remote/regional areas, having difficulty in managing income, having a chronic condition, reporting poor/fair self-rated health, and lower SF-36 quality of life scores were associated with an increased odds of being a member of the following classes: 1) moderate to high-level HACC/CACP, 2) increasing RAC, and 3) early mortality, compared with the non-user class.
CONCLUSIONS: Distinct patterns of aged care use were identified. These results will facilitate future capacity planning for aged care systems in Australia.

Gender differences in the association between migration and cognitive function among older adults in China and India.

Arch Gerontol Geriatr. 2018 Nov 22;81:31-38

Authors: Xu H, Vorderstrasse AA, Dupre ME, McConnell ES, Østbye T, Wu B

Abstract
OBJECTIVE: This study aims to examine gender differences in the association between migration and cognitive function among adults in China and India.
METHODS: Data from the World Health Organization Study on global AGEing and adult health (SAGE) study were used that included adults aged 50 + from China (N = 12,937) and India (N = 6244). Migration status included: urban residents, rural residents, urban-to-urban, rural-to-urban, rural-to-rural, and urban-to-rural migrants. Cognitive function was assessed by immediate and delayed recall tests, digit span tests, and verbal fluency test. Ordinary least square regression models were used to adjust for sociodemographic characteristics, psychosocial factors, health behaviors, and physical health status.
RESULTS: Controlling for multiple covariates, significant differences in cognitive function were found between men and women, and across migration groups. A consistent female disadvantage was found in China and India for cognitive function. Women who were rural residents or rural-to-rural migrants had the poorest cognitive function in both the Chinese and the Indian samples. Among males in China, rural residents had poorer cognitive function than urban residents, while urban-to-urban migrants had highest cognition scores; however, for male counterparts in India, rural-to-rural migrants had the poorest cognitive function.
CONCLUSIONS: The results suggest that the association between migration and cognitive function differs by gender and country. In our study populations, major sociodemographic characteristics play a key role in accounting for the differences in cognitive function.

Correlation Between Lower Third Molar Impaction Types and Mandibular Angle and Condylar Fractures: A Retrospective Study.

Correlation Between Lower Third Molar Impaction Types and Mandibular Angle and Condylar Fractures: A Retrospective Study.

J Oral Maxillofac Surg. 2018 Sep 29;:

Authors: Samieirad S, Eshghpour M, Dashti R, Tohidi E, Javan AR, Mianbandi V

Abstract
PURPOSE: The purpose of this study was to investigate and determine the relations between mandibular third molar (M3) impaction types and mandibular angle and condylar fractures.
MATERIALS AND METHODS: A retrospective study was conducted in patients with mandibular angle and condylar fractures referred to the Oral and Maxillofacial Surgery Department of the Shahid Kamyab Hospital (Mashhad, Iran) from 2013 to 2018. Data sources were patients' hospital documents and panoramic radiographs. Predictor variables were the presence and position of impacted M3s. The Pell-Gregory classification was used to identify the horizontal and vertical positions of impaction. The impaction angulation was determined using the Schiller classification. Outcome variables were the presence of angle and condylar fractures. Data were analyzed using SPSS 16 (IBM Corp, Armonk, NY) and χ2 and Fisher exact tests.
RESULTS: The study sample consisted of 117 patients (63.2% with condylar fractures, 30.8% with angle fractures, and 6% with concomitant fractures of the condyle and angle). Most patients (88.9%) with angle fracture had impacted M3s; however, impacted M3s were absent in 59.5% of condylar fracture cases. Mesioangular and vertical positions were the most prevalent impaction angulation types in patients with mandibular angle fracture. Classes II and B were the most frequent horizontal and vertical impaction types, respectively, according to the Pell-Gregory classification. There was a statistically significant difference between fracture site and the presence or absence of impacted M3s (P < .001). Moreover, a significant relation was observed between horizontal impaction type and fracture site in patients with impacted M3s (P = .001).
CONCLUSIONS: The presence of impacted M3s increased the risk of angle fractures and simultaneously decreased the risk of condylar fractures. Fractures of the angle region were more commonly seen in patients with superficially impacted (vs deeply impacted) M3s.

Does Low-Level Laser Therapy Affect Recovery of Lingual and Inferior Alveolar Nerve Injuries?

Does Low-Level Laser Therapy Affect Recovery of Lingual and Inferior Alveolar Nerve Injuries?

J Oral Maxillofac Surg. 2018 Dec;76(12):2669-2675

Authors: Miloro M, Criddle TR

Abstract
PURPOSE: Iatrogenic damage to the inferior alveolar nerve (IAN) and lingual nerve (LN) may occur during routine oral and maxillofacial surgery procedures. The primary aim of this study was to determine, using a prospective, double-blind, randomized controlled clinical trial, whether the proportion of nerve-injured patients with postoperative neurosensory improvement over a 3-month period differed significantly between a control group and a low-level laser therapy (LLLT) group.
PATIENTS AND METHODS: The study sample consisted of 35 patients with iatrogenic nerve injury due to third molar odontectomy, dental implant placement, or local anesthetic injection. The investigators used a randomized, double-blind laser delivery system to administer either placebo or LLLT to patients who met the inclusion criteria. The outcome variable of neurosensory improvement was defined as a minimum 1-unit increase from baseline in visual analog scale rating and was based on standard objective clinical neurosensory testing. Study variables included the affected nerve (IAN or LN) and time from injury to treatment (3 to 12 months or >12 months). Univariate statistical analysis (χ2 test) was performed to determine significance between the groups.
RESULTS: Neurosensory improvement was observed in 46.7% of the LLLT patients, who showed at least a 1-unit improvement at 3 months, compared with 38.5% improvement for controls (P = .66), regardless of the specific nerve involved (IAN or LN). In addition, no observed difference was noted between the study groups based on time from injury to treatment.
CONCLUSIONS: This study failed to provide sufficient evidence to conclude that a difference in neurosensory improvement exists between the LLLT and placebo groups with IAN or LN injuries. However, this study is unique in the prospective double-blind study design and comprehensive neurosensory testing protocols. There is a continued need for further clinical studies on LLLT in oral and maxillofacial surgery nerve injuries.

Dynamic Stability Assessment of the Temporomandibular Joint as a Sequela of Open Reduction and Internal Fixation of Unilateral Condylar Fracture.

Dynamic Stability Assessment of the Temporomandibular Joint as a Sequela of Open Reduction and Internal Fixation of Unilateral Condylar Fracture.

J Oral Maxillofac Surg. 2018 Dec;76(12):2598-2609

Authors: Kuntamukkula S, Sinha R, Tiwari PK, Paul D

Abstract
PURPOSE: Dynamic stability of the temporomandibular joint (TMJ) is the characteristic of the joint to achieve normal function by harmonious, balanced, synchronized interactions of the various functional subunits of the stomatognathic system. The aim of this study was to evaluate changes in the mechanics and dynamics of the TMJ during recovery from surgical treatment of an isolated condylar fracture.
PATIENTS AND METHODS: This is a prospective cohort study involving 30 patients who underwent open reduction and internal fixation for an isolated unilateral condylar fracture and were clinically asymptomatic at 6 months after surgery. The dynamics of the TMJ were assessed by bite-force analysis, both static and dynamic, to assess masticatory efficiency. Surface electromyography was recorded to assess changes in muscle dynamics. Joint vibration analysis was performed to evaluate the internal functioning of the TMJ. All the assessments were carried out bilaterally to allow comparison of the injured and uninjured joints, and the data were analyzed with the paired t test and independent-samples t test. Statistical significance was considered at P < .05.
RESULTS: The study included 18 male and 12 female patients aged between 20 and 40 years. Bite-force analyses showed significantly higher bite forces on the uninjured side at 6 months after surgery. Similarly, surface electromyography analysis showed increased muscle activity on the affected side pointing toward some compensatory hyperactivity in the masticatory muscles. Joint vibration analysis showed that there was increased friction during function in both the injured and uninjured joints.
CONCLUSIONS: The observations in this study suggest that residual imbalances are present in the TMJ at 6 months after open reduction and internal fixation of condylar fractures. Therefore, long-term studies are required to establish a complete timeline of adaptive changes occurring in the TMJ after condylar fractures, especially in comparison with other treatment modalities.

Role of Non-Albicans Candida and Candida Albicans in Oral Squamous Cell Cancer Patients.

J Oral Maxillofac Surg. 2018 Dec;76(12):2564-2571

Authors: Mäkinen A, Nawaz A, Mäkitie A, Meurman JH

Abstract
PURPOSE: This study examined the prevalence of Candida species in the saliva of oral squamous cell carcinoma patients and its effect on the mortality rate.
MATERIALS AND METHODS: One hundred patients with oral cavity squamous cell carcinoma undergoing protocol treatment at Helsinki University Hospital were recruited into the study from March 2011 through 2014. For comparison, 75 age-matched controls with no current or previously treated oral cancer were recruited. Paraffin-stimulated whole saliva samples were collected and cultivated on CHROMagar Candida medium (CHROMagar, Paris, France) to establish possible Candida growth. The API ID 32C yeast identification kit (bioMérieux, Lyon, France) and Bichro-Dubli Fumouze latex agglutination test (Fumouze Diagnostics, Levallois-Perret, France) were used for further identification of different Candida species. Patients' medical records were studied for information on their health habits and general health status, as well as tumor-related data. The patients' status regarding being alive and cancer free was checked at a follow-up point in December 2017. Descriptive statistics and cross tabulation were carried out, and the P value was set at .05.
RESULTS: Candida species were detected in 74% of the oral cancer patients' samples, with C. albicans being the most common species (84%). Other species identified were C. dubliniensis (8%), C. tropicalis (4%), C. glabrata (3%), C. parapsilosis (3%), C. sake (3%), C. krusei (1%), and C. guilliermondii (1%). After the follow-up period, 63% of the patients were alive and 86% of them were cancer free. Harboring Candida species in the saliva was not associated with any increase in the mortality rate.
CONCLUSIONS: C. albicans was common in the oral cavity of the oral squamous cell carcinoma patients. However, in this patient population, we did not observe a statistically significant effect of the yeast on the mortality rate.

Abstract
PURPOSE: To review cases of suppurative osteomyelitis of the jaws treated at the Massachusetts General Hospital (Boston, MA) over a 10-year period, evaluate specifics of disease presentation, and answer the clinical question: are there identifiable variables associated with treatment outcome?
MATERIALS AND METHODS: A retrospective cohort study was completed using patients treated for suppurative osteomyelitis of the jaws at the Massachusetts General Hospital from April 2006 to October 2016. Inclusion criteria were a diagnosis of suppurative osteomyelitis of the jaw, age older than 18 years, and complete medical records. Patients with nonsuppurative disease, radiation history, or antiresorptive exposure were excluded. Candidate variables included demographic information, medical and dental history, presenting signs and symptoms, and radiologic and laboratory findings. The outcome variable was successful treatment, defined as resolution of symptoms and radiographic evidence of healing after initial treatment. Appropriate statistical analyses were performed with significance set a P value less than .05.
RESULTS: Forty-two patients met the inclusion criteria. Mean age was 53 years (range, 20 to 80 yr) and 26 were women (62%). Common comorbidities included cardiovascular disease (52%), tobacco use (45%), and psychiatric disorders (45%). Pain (90%), swelling (86%), and neurosensory change (50%) were the most common findings. Common microbacterial isolates included Streptococcus milleri (74%) and coagulase-negative Staphylococcus species (43%), which showed marked antibiotic resistance. Surgical debridement was the most common intervention (93%). Successful treatment was found in 86%. Of 6 persistent cases, 4 resolved with a second debridement and continued antibiotics and 2 required resection. Increased white blood cell (WBC) count at presentation (P = .005) and associated psychiatric diagnoses (P = .037) were statistically associated with unsuccessful initial treatment.
CONCLUSION: The results of this study indicate that antibiotic resistance is commonly encountered in this patient population, although it was not associated with unsuccessful outcome. Patients presenting with increased WBC count and concurrent psychiatric comorbidities required protracted treatment.
