A Case of Bilateral Anesthesia Mumps after Cesarean Section under Spinal Anesthesia: A Rare Case and Literature Review.

A 30-year-old pregnant female presented to the emergency department with labor pain in her 39th week of pregnancy. Cesarean section under spinal anesthesia was the chosen route of delivery for this patient due to previous cesarean section in her first pregnancy. The delivery itself was uneventful but seven hours after the surgery, bilateral swelling of parotid glands were noted. Rehydration therapy and a single dose of hydrocortisone (100 mg IV route) were administered, and swellings were completely resolved on postoperative day 2. This is one of the rare cases of anesthesia mumps after spinal anesthesia, and we think rehydration therapy and the single dose corticosteroid may prove useful in these cases.

Women's sexual function before and during COVID-19 pandemic: A systematic review and meta-analysis.

BACKGROUND: To systematically review and summarize the available literature regarding the women's sexual function during COVID-19 pandemic and compare it to pre-pandemic period. METHODS: We searched PubMed and Embase from the inception of the databases until 15th April 2021. Data regarding the sexual function, measured by female sexual function index (FSFI), of adult sexually active women were extracted from the eligible studies and compared between the before and during the COVID-19 pandemic. The secondary outcome was the frequency of intercourse during pandemic time. The random-effect model was used to pool the mean differences and corresponding 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 value. RESULTS: Our search resulted in a sample of six eligible studies, which involved 1114 female participants. The total FSFI score among study participants during pandemic was 22.93 (95% CI: 19.26-26.59), which indicated a significant decrease in sexual function of women during pandemic as compared to pre-pandemic time (mean difference = -3.80, 95% CI: -6.48 to -1.12, p = 0.005, I2  = 96%). We also conducted a meta-analysis of individual FSFI domains. During pandemic, women had problems with arousal (p < 0.0001), orgasm (p = 0.0008), satisfaction (p = 0.0009), and pain (p = 0.009). No significant difference in frequency of intercourse was observed between pre- and during pandemic (p = 0.80). Furthermore, no significant publication bias was present among included studies. CONCLUSION: Overall, there was a significant decrease in sexual function of sexually active adult women during COVID-19 pandemic. The most affected areas of sexual function were arousal, orgasm, pain, and satisfaction. Physicians must be aware of COVID-19 impact on sexual life of women and provide proper counseling.

Application of posterior canal skin flap for the repair of large tympanic membrane perforations.

Objective: Many methods have been described for the repair of the tympanic membrane, but there is no general consensus as to the standard method. The aim of this study was to evaluate the effect of the inferior base posterior canal skin flap on the graft success rate in large tympanic membrane perforations. Methods: After the post-auricular incision, the posterior canal skin flap with inferior pedicle was created by two vertical and one horizontal incisions. Then the flap was rotated over the temporalis fascia graft. The graft success rate and postoperation hearing test results were evaluated in 52 patients who suffered from large tympanic membrane perforations. Results: We achieved a 92.3% total graft success rate with about 9 dB improvement in speech reception threshold (SRT). Conclusion: The rotational inferior base posterior canal skin flap tympanoplasty technique is simple, fast, safe, and effective for the repair of subtotal tympanic membrane perforations.

A Systematic Review of Imaging Studies in Olfactory Dysfunction Secondary to COVID-19.

RATIONALE AND OBJECTIVES: Hyposmia/anosmia is common among patients with coronavirus disease-2019 (COVID-19). Various imaging modalities have been used to assess olfactory dysfunction in COVID-19. In this systematic review, we sought to categorize and summarize the imaging data in COVID-19-induced anosmia. MATERIAL AND METHODS: Eligible articles were included after a comprehensive review using online databases including Google scholar, Scopus, PubMed, Web of science and Elsevier. Duplicate results, conference abstracts, reviews, and studies in languages other than English were excluded. RESULTS: In total, 305 patients undergoing MRI/functional MRI (177), CT of paranasal sinuses (129), and PET/CT or PET/MRI scans (14) were included. Out of a total of 218 findings reported on MRI, 80 were reported on early (≤ 1 month) and 85 on late (>1 month) imaging in relation to the onset of anosmia. Overall, OB morphology and T2-weighted or FLAIR signal intensity were normal in 68/218 (31.2%), while partial or complete opacification of OC was observed in 60/218 (27.5%). T2 hyperintensity in OB was detected in 11/80 (13.75%) and 18/85 (21.17%) on early and late imaging, respectively. Moreover, OB atrophy was reported in 1/80 (1.25%) on early and in 9/85 (10.58%) on late imaging. Last, among a total of 129 CT scans included, paranasal sinuses were evalualted in 88 (68.21%), which were reported as normal in most cases (77/88, [87.5%]). CONCLUSION: In this systematic review, normal morphology and T2/FLAIR signal intensity in OB and OC obstruction were the most common findings in COVID-19-induced anosmia, while paranasal sinuses were normal in most cases. OC obstruction is the likely mechanism for olfactory dysfunction in COVID-19. Abnormalities in OB signal intensity and OB atrophy suggest that central mechanisms may also play a role in late stage in COVID-19-induced anosmia.

Role of peroxisome proliferator-activated receptor gamma (PPARγ) in the regulation of fatty acid metabolism related gene expressions in testis of men with impaired spermatogenesis.

Although male infertility is a multifactorial syndrome in which genetic factors are responsible for up to 15 % of cases, there are few studies of genes involved in lipid metabolism and male infertility. Peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-activated transcription factor in testis tissue. PPARγ binds to DNA and regulates the genes for fatty acid (FA) metabolism. Thus, it has a key role in male reproduction. The current study assessed the expressions of fatty acid desaturase 2 (FADS2), elongation of very-long-chain fatty acids-like 2 (ELOVL2), stearoyl-CoA desaturase-1 (SCD), and lipoprotein lipase (LPL) and incorporation of PPARγ in the promoter regions of these genes in testicular tissue biopsies from 30 infertile males who underwent testicular sperm extraction. The samples were classified into three groups: obstructive azoospermia (OA), which was the positive control (n = 10); round spermatid maturation arrest (SMA, n = 10); and Sertoli cell-only syndrome (SCOS, n = 10). There were significantly lower relative mRNA expression levels of the FADS2, ELOVL2, SCD, and LPL genes in the SCOS (P < 0.01) and SMA (P < 0.01) groups compared to the OA control group. We observed a significant decrease in chromatin incorporation of PPARγ on the promoter regions of the candidate FA metabolism genes (P < 0.05). For the first time, the present study results show that PPARγ is a strong mediator for regulation of FA metabolism in human testis tissue and we confirmed its critical role in normal spermatogenesis.
