Purpose: In the literature on stapes surgery, various materials have been used to seal the vestibulotomy. To date, there are only a few published randomized clinical trials with focus on hearing outcomes, using different sealing materials. Hence, the aim of this study was to compare hearing outcomes when using fat or Hyaluronic acid gel (HAG) to seal the stapedotomy.

Methods: The present double-blind, prospective, randomized clinical trial was conducted on ears undergoing stapedotomy in Dasthgheib Hospital, a referral otology center in Southern Iran, and Dena private hospital, Shiraz Iran. A total of 150 primary stapedotomies were evaluated, and sealing material was fat in 77 ears and HAG in 73.

Results: 60 (77.9%) of the fat group ears and 63 (86.3%) of the HAG group ears obtained postoperative air-bone gap (ABG) within 20 dB, but the difference was not significant (p = 0.182).

Conclusion: As a sealing material in stapedotomy, HAG is comparable with fat in terms of hearing outcomes. Therefore, HAG is recommended as a safe sealing material in stapedotomy.

Elevated Levels of T-helper 17-associated Cytokines in Diabetes Type I Patients: Indicators for Following the Course of Disease.

Background: Type 1 diabetes (T1D) is thought to involve chronic inflammation, which is manifested by the activation and expression of different inflammatory mediators. Th1- and Th17-associated cytokines are factors that have been shown to exert profound pro-inflammatory activities and have been implicated in the pathogenesis of T1D in mice and humans.

Objectives: Therefore, the aim of this case control study was to determine the serum level of IL-17, IL-21, IL-27, transforming growth factor beta (TGF-β), and IFN-γ and their reciprocal relationship in Iranian T1D patients.

Patients And Methods: Blood samples were collected from 48 T1D patients and 49 healthy individuals with no history of malignancies or autoimmune disorders based on simple sampling. The serum levels of IL-17, IL-21, IL-27, TGF-β, and IFN-γ were measured by the enzyme linked immunosorbent assay (ELISA).

Results: The serum levels of IL-17 and IL-21 were significantly higher in T1D patients compared to the healthy individuals (p = 0.005 and 0.01, respectively), but interestingly, the opposite was the case for IL-27 (p < 0.0001). However, there were no significant differences in TGF-β and IFN-γ between both groups. In addition, IL-17/IFN-γ and IL-17/IL-27 ratios were higher in patients compared to the control group.

Conclusions: Our results indicated dominant Th17-associated IL-17, suggesting a shift from the Treg and Th1 phenotypes toward the Th17 phenotype. Therefore, it can promote inflammation in β cells in T1D. In addition, it suggests the role of Th17 and Th17/Th1 ratios as a potential contributor to β cells destruction and the Th17/Th1 response ratio may provide a novel biomarker for rapid T1D diagnosis before the destruction of β cells and progression of the disease to the clinical end stages.
