Free and total vitamin d in psoriatic patients treated with biological drugs

xlomafota13 shared this article with you from Inoreader

Abstract

Data regarding the association between psoriasis and vitamin D levels are controversial [S1‐S2], maybe due to the choice of dosing serum total 25(OH)D in order to assess the vitamin D nutritional state both at its basal levels and after supplementation [S3‐S4].

Abstract

Otolaryngologists and speech therapist can be experts in managing specific puberphonia lesions to improve voice. However, not all voice problems have lesions amenable to surgical or medical therapies. Many are associated with maladaptive speech behaviors. We may employ a variety of techniques to improve vocal quality and function in patients with and without structural or neurologic laryngeal pathology. There is an alarming increase in cases of puberphonia and it's after effects. Otolaryngologists can partner to manage a constellation of puberphonia voice problems with directed voice evaluation and therapy. We, in a small Otorhinolarygolist center in a small city, Chennai has registered and treated 600 cases of puberphonia. We are able to register the devastating problems of puberphonia. Regarding the treatment of puberphonia, in which laryngeal massage, outside the neck, is consistently highlighted as being an effective therapy technique for treating it. In ad dition, there have been several individual studies conducted to examine the effectiveness of laryngo pharyngeal manipulation inside the vocal tract, which also yielded positive results. A basic review of UMAR techniques and this partnership with yoga breathing trainers is presented which give almost immediate low pitch speech and give a good follow up.

Letter to Editor on “Changes in Acoustic Aspects of Voice Function in Children After Adenotonsillectomy”

xlomafota13 shared this article with you from Inoreader
We read with great interest the article by Brkic et al on changes in Acoustic Aspects of Vocal Function in Children After Adenotonsillectomy.1 They have reported significant differences in the fundamental frequency, jitter, shimmer and harmonic noise ratio immediately after surgery.1 Of these the fundamental frequency was the earliest to return to normal in one month. This finding is used to allay the concerns of the parents regarding voice change. We commend the authors for sharing their valuable experience with voice change after adenotonsillectomy.

ABSTRACT

Shoulder pathology is a very common medical presentation and can be due to anatomical variations. Therefore, knowledge of variants is important for the clinician treating patients with such complaints so that misdiagnosis is minimized and iatrogenic injury prevented. A review of the literature was performed of the variant anatomy of the pectoralis minor muscle. The aim of this revi ew is to better inform clinicians who might treat patients with shoulder pathology so that if identified, variants of the pectoralis minor muscle are better appreciated.

Surg Radiol Anat. 2021 Mar 9. doi: 10.1007/s00276-021-02691-z. Online ahead of print.

ABSTRACT

PURPOSE: To investigate the effect of the clival bone pattern on the abducens nerve (AN) localization in the petroclival region between the Pediatric and Adult Groups.

METHODS: This study used 12 pediatric and 17 adult heads obtained from the autopsy. The length and width of the clivus and the length of the petrosphenoidal ligaments (PSLs) were measured. The ratio of the leng th and width of the clivus was accepted as the clival index (CI). The localization of the AN at the petroclival region below the PSL, classified as lateral and medial, were recorded.

RESULTS: The average length of the clivus was 26.92 ± 2.88 mm in the Pediatric Group, and 40.66 ± 4.17 mm in the Adult Group (p < 0.001). The average width of the clivus was 22.35 ± 2.88 mm in the Pediatric Group, and 29.96 ± 3.86 mm in the Adult Group (p < 0.001). The average value of the CI was 1.20 in the Pediatric Group and 1.36 in the Adult Group (p = 0.003). The length of the PSL was 7.0 ± 1.47 mm in the Pediatric Group and 11.05 ± 2.95 mm in the Adult Group (p < 0.001). The nerve was located below the medial side of the PSL in the Pediatric Group and below the lateral side in the Adult Group (p = 0.002).

CONCLUSIONS: The petrous apex localization of the AN in adults compared with pediatric subjects could be related to the increased growth in the length of the clivus tha n its width.

Surg Radiol Anat. 2021 Mar 9. doi: 10.1007/s00276-021-02726-5. Online ahead of print.

ABSTRACT

PURPOSE: This study aimed to compare the students' scores of the spot (spotter/classical/traditional/tag/ring/bell-ringer) test (3D environment) performed in the laboratory with the slide test (gross anatomy images) (2D environment) in the class. The observation of our department regarding both types for practical examination was reported, in terms of exam marks of the students. Bo th are preferred as the practical examination types for gross anatomy course our in medical faculty.

METHODS: The 29 blocks' scores in 5 years (2013/2014-2017/2018) belonging to first- and second-year medical students' spot tests and slide tests are evaluated retrospectively and statistically compared. Correlations of the spot tests and the slide tests, besides the correlations between theoretical examinations and the practical examination types, are calculated.

RESULTS: Spot test scores were significantly higher (p < 0.05) in nine blocks, while slide test scores were higher significantly (p < 0.05) in fourteen. There was no statistically significant difference between the practical examination types (spot/slide) in six blocks. There were correlations between the spot test and the slide test in all blocks (p < 0.001).

CONCLUSION: It is considered that the spot test reflects the success/ability in a 3D environment, while the slide test reflects it in the 2D environment. In conclusion, neither of these two types of examinations stands out absolutely. Both types of examinations have their own features in areas, such as assessment power, applicability, and effect on success.

Auditory and imaging markers of atypical enlarged vestibular aqueduct

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 Mar 9. doi: 10.1007/s00405-021-06700-0. Online ahead of print.

ABSTRACT

PURPOSE: To characterize the auditory and imaging markers of atypical enlarged vestibular aqueduct (EVA).

METHODS: 15 EVA cases (26 ears) confirmed via high-resolution MRI (HRMRI) that did not meet the Valvassori criterion on high-resolution CT (HRCT) were classified as atypical EVA. Another 21 EVA cases (40 ears) meeting the Valvassori criterion were randomly chosen as typical EVA. The hearing loss (HL), HRCT, and HRMRI findings were compared between the two groups.

RESULTS: The difference of HL severity between atypical and typical EVA was not statistically significant (χ2 = 0.12, P > 0.05. The vestibular aqueducts (VA) of atypical EVA cases manifested as borderline dilation (n = 17), focal dilation (n = 3), and normal appearance (n = 6) on the HRCT. The midpoint width of atypical and typical EVA cases wa s 1.06 ± 0.18 mm and 2.10 ± 0.55 mm, respectively, exhibiting a significant difference (t = - 9.20, P < 0.05). In the HRMRI, the degree of dilation and shape of the intraosseous partition of endolymphatic duct and sac (ES) was similar to that of VA on HRCT, while their extraosseous ES was depicted variable slighter dilation compared to that of typical one, the difference between them was statistically significant (t = - 4.10, P < 0.05).

CONCLUSION: The HL severity of atypical EVA ears was similar to that of typical ones. Nevertheless, borderline, focal dilation and normal-like appearance of VAs on HRCT and variablely slighter dilation of the extraosseous ES on HRMRI are its characteristic imaging findings.
