Extracapsular dissection by the sternocleidomastoid muscle–parotid space approach reduces the risks of postparotidectomy sialocele and salivary fistula

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Postoperative sialoceles and fistulas are frequent surgical complications of parotid tumor resection. Extracapsular dissection by the sternocleidomastoid muscle–parotid space approach (ECD-SMPSA) is a minimally invasive technique. To our knowledge, the characteristics of sialoceles and fistulas secondary to ECD-SMPSA have not been reported.

Methods

This prospective study enrolled 52 patients who underwent ECD-SMPSA without sialocele/fistula prevention measures. Postoperative sialoceles and fistulas were evaluated during 2 months of follow-up.

Results

Among the 52 patients, only one male patient developed a mild sialocele. No salivary fistulas occurred. The overall rate of sialocele/fistula formation was 1.92%.

Conclusions

When treating clinically benign tumors that involve the sternocleidomastoid muscle–parotid space, ECD-SMPSA may prevent postoperative formation of sialoceles and salivary fistulas.

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

This systematic review and meta-analysis aims to estimate the prevalence and prognostic impact of retropharyngeal lymph node metastases (RLNMs) in oropharyngeal squamous cell carcinoma (OPSCC).

Methods

This meta-analysis was conducted according to PRISMA guidelines. Inclusion criteria: studies with more than 20 patients reporting the prevalence or prognostic impact of RLNMs in OPSCC. Whenever available, data on HPV status and subsites were extracted.

Results

Twenty-two articles were included. The overall prevalence of RLNMs in OPSCC was 13%, with no significant differences depending on HPV status. The highest prevalence was observed for posterior pharyngeal wall SCC (24%), followed by soft palate (17%), palatine tonsil (15%), and base of tongue (8%). RLNMs were associated with a significantly higher risk of death (HR:2.54;IC95%1.89–3.41) and progression (HR:2.44;IC95%1.80–3.30).

Conclusions

The prevalence of RLNMs in OPSCC was 13%, being higher in tumors of the posterior pharyngeal wall. RLNMs were associated with unfavorable outcomes.

Clinical features, diagnosis and management of cephalosporin-induced acute generalized exanthematous pustulosis

We collected original research, clinical trial reports, case reports and reviews of cephalosporin-induced acute generalized exanthematous pustulosis (AGEP) by searching Chinese and English databases to explore the clinical features, treatment strategies and prognosis of cephalosporin -induced AGEP.


Abstract

What is Known and Objective

Acute generalized exanthematous pustulosis (AGEP) is a serious and rare adverse reaction of cephalosporins. We aimed to describe the clinical features of cephalosporin-induced AGEP and provide a reference for rational clinical use of cephalosporins.

Methods

We systematically searched Chinese and English databases for cephalosporin-induced TGEP-related case reports, retrospective studies, clinical studies, and review articles published before May 2022.

Results and Discussion

A total of 43 patients from 35 articles were eligible, of which 28 (65.1%) were female, with a median age of 69 years. A total of 11 cephalosporins were suspected, the most commonly involved were ceftriaxone (41.9%), cephalexin (16.3%), and cefepime (9.3%). AEGP erupted primarily within 14 days after administration, manifested as nonfollicular pustules on an erythematous base, distributed favourably to the extremities (44.2%), trunk (23.3%), face (23.3%), and could involve the oral mucosa (11.6%). During AGEP resolution, the affected area had desquamation (39.5%). The acute phase of the disease may be accompanied by fever (>38.0°C) and elevated neutrophil count (>7500/mm3). Histology of AGEP showed subcorneal pustules (56.3%), intraepidermal cavernous pustules (37.5%), with papillary dermal edema (37.5%), containing neutrophils and eosinophilic infiltration (71.9%). After drug discontinuation, the median time to resolution of AGEP symptoms was 10 days (rang e 2, 90).

What is New and Conclusion

Cephalosporin-induced AGEP is rare and should be properly diagnosed. This serious cutaneous adverse reaction is self-limiting and has a favourable prognosis, usually resolves with drug interruption, and may require additional interventions, such as topical steroids.

The ICEBERG: A score and visual representation to track the severity of traumatic brain injury: Design principles and preliminary results

alexandrossfakianakis shared this article with you from Inoreader
imageBACKGROUND Establishing neurological prognoses in traumatic brain injury (TBI) patients remains challenging. To help physicians in the early management of severe TBI, we have designed a visual score (ICEBERG score) including multimodal monitoring and treatment-related criteria. We evaluated the ICEBERG scores among patients with severe TBI to predict the 28-day mortality and long-term disability (Extended Glasgow Outcome Scale score at 3 years). In addition, we made a preliminary assessment of the nurses and doctors on the uptake and reception to the use of the ICEBERG visual tool. METHODS This study was part of a larger prospective cohort study of 207 patients with severe TBI in the Parisian region (PariS-TBI study). The ICEBERG score included six variables from multimodal monitoring and treatment-related criteria: cerebral perfusion pressure, intracranial pressure, body temperature, sedation depth, arterial partial pressure of CO2, and blood osmolarity. The primary outcome measures included the ICEBERG score and its relationship with hospital mortality and Extended Glasgow Outcome Score. RESULTS The hospital mortality was 21% (45/207). The ICEBERG score baseline value and changes during the 72nd first hours were more strongly associated with TBI prognosis than the ICEBERG parameters measured individually. Interestingly, when the clinical and computed tomography parameters at admission were combined with the ICEBERG score at 48 hours using a multimodal approach, the predictive value was significantly increased (area under the curve = 0.92). Furthermore, comparing the ICEBERG visual representation with the traditional numerical readout revealed that changes in patient vitals were more promptly detected using ICEBERG representation (p

Failure to rescue in trauma: Early and late mortality in low- and high-performing trauma centers

alexandrossfakianakis shared this article with you from Inoreader
imageBACKGROUND Failure to rescue (FTR) is defined as mortality following a complication. Failure to rescue has come under scrutiny as a quality metric to compare trauma centers. In contrast to elective surgery, trauma has an early period of high expected mortality because of injury sequelae rather than a complication. Here, we report FTR in early and late mortality using an externally validated trauma patient database, hypothesizing that centers with higher risk-adjusted mortality rates have higher risk-adjusted FTR rates. METHODS The study included 114,220 patients at 34 Levels I and II trauma centers in a statewide quality collaborative (2016–2020) with Injury Severity Score of ≥5. Emergency department deaths were excluded. Multivariate regression models were used to produce center-level adjusted rates for mortality and major complications. Centers were ranked on adjusted mortality rate and divided into quintiles. Early deaths (within 48 hours of presentation) and late deaths (after 48 hours) were analyzed. RESULTS Overall, 6.7% of patients had a major complication and 3.1% died. There was no difference in the mean risk-adjusted complication rate among the centers. Failure to rescue was significantly different across the quintiles (13.8% at the very low-mortality centers vs. 23.4% at the very-high-mortality centers, p

Prospective randomized trial of metal versus resorbable plates in surgical stabilization of rib fractures

alexandrossfakianakis shared this article with you from Inoreader
imageBACKGROUND Surgical stabilization of rib fractures has gained popularity as both metal and resorbable plates have been approved for fracture repair. Is there a difference between metal and resorbable plate rib fixation regarding rib fracture alignment, control of pain, and quality-of-life (QOL) scores (Rand SF-36 survey)? METHODS Eligible patients (pts) included 18 years or older with one or more of the following: flail chest, one or more bicortical displaced fractures (3–10), nondisplaced fractures with failure of medical management. Patients were randomized to either metal or resorbable plate fixation. Primary outcome was fracture alignment. Secondary outcomes were pain scores, opioid use, and QOL scores. RESULTS Thirty pts were randomized (15 metal/15 resorbable). Total ribs plated 167 (88 metal/79 resorbable). Patients with rib displacement at day of discharge (DOD) metal 0/14 (one pt died, not from plating) versus resorbable 9/15 or 60% (p = 0.001). Ribs displaced at DOD metal 0/88 versus resorbable 22/79 or 28% (p

Development and implementation of an automated electronic health record–linked registry for emergency general surgery

alexandrossfakianakis shared this article with you from Inoreader
imageINTRODUCTION Despite adoption of the emergency general surgery (EGS) service by hospitals nationally, quality improvement (QI) and research for this patient population are challenging because of the lack of population-specific registries. Past efforts have been limited by difficulties in identifying EGS patients within institutions and labor-intensive approaches to data capture. Thus, we created an automated electronic health record (EHR)–linked registry for EGS. METHODS We built a registry within the Epic EHR at University of California San Diego for the EGS service. Existing EHR labels that identified patients seen by the EGS team were used to create our automated inclusion rules. Registry validation was performed using a retrospective cohort of EGS patients in a 30-month period and a 1-month prospective cohort. We created quality metrics that are updated and reported back to clinical teams in real time and obtained aggregate data to identify QI and research opportunities. A key metric tracked is clinic schedule rate, as we care that discontinuity postdischarge for the EGS population remains a challenge. RESULTS Our registry captured 1,992 patient encounters with 1,717 unique patients in the 30-month period. It had a false-positive EGS detection rate of 1.8%. In our 1-month prospective cohort, it had a false-positive EGS detection rate of 0% and sensitivity of 85%. For quality metrics analysis, we found that EGS patients who were seen as consults had significantly lower clinic schedule rates on discharge compared with those who were admitted to the EGS service (85% vs. 60.7%, p
