MicroRNAs (miRNAs) play an important role in regulating gene expression at the post-transcriptional level and are involved in numerous physiological processes. Accumulating evidence suggests that single-nucleotide polymorphisms (SNPs) in human miRNA genes may affect miRNA biogenesis pathway and influence the susceptibility to several diseases such as cancer. The present study aimed to evaluate the impact of miR-499 rs3746444, miR-196a2 rs11614913, miR-149 rs2292832, and miR-146a rs2910164 polymorphisms on prostate cancer (PCa) risk in a sample of Iranian population. This case-control study was done on 169 patients with pathologically confirmed PCa and 182 benign prostatic hyperplasia (BPH). The genotyping assays were done using T-ARMS-PCR or PCR-RFLP methods. The findings indicated that CC genotype of miR-499 rs3746444 polymorphism increased the risk of PCa (OR = 1.76, 95% CI = 1.12-2.79, P = 0.019) compared to TT genotype. No statistically significant association was found between miR-196a2 rs11614913, miR-149 rs2292832, and miR-146a rs2910164 polymorphisms and PCa risk. In summary, the findings indicated that miR-499 rs3746444 polymorphism increased the risk of PCa in an Iranian population. Further studies with larger sample sizes and different ethnicities are necessary to verify the findings of the present study.

Introduction: Acute parotitis is known as an uncommon disease in children and a rare condition in infancy. Dehydration, prematurity, immune deficiency, congenital anomalies of the parotid gland or ducts, and oral trauma are some of its important risk factors. The most common bacteria contributing to this condition is Staphylococcus aureus. Acute parotitis is managed with intravenous antibiotic therapy and surgery in complicated cases. Favorable prognosis is reported in early diagnosis and proper antibiotic therapy. Case Presentation: The present report presents the case of a 60-day-old breastfed female infant with a chief complaint of agitation referred to the Department of Pediatrics in a university-affiliated hospital in Tehran, Iran, in 2018. She underwent treatment for the infantile colic diagnosis. Conclusions: Timely diagnosis and treatment of acute bacterial parotitis prevented suppurative parotitis and formation of abscess.

Background: Studies on the relationship of urinary sodium with overweight and obesity led to controversial results. Furthermore, no study has ever investigated the association between sodium status and obesity in Iranian adults. The present study examined the association of urinary sodium levels with overweight and obesity in adults living in Yazd, Iran. Methods: The present study recruited 240 adults randomly selected from adults, who participated in Yazd Health Study (YaHS). A 24-hour urine sample was collected from the participants. Participants' demographic information, history of chronic diseases, and smoking status were obtained. The height and weight of the participants were also assessed using standard methods. We compared the weight and body mass index (BMI) of the participants based on the urinary sodium excretion tertiles. The logistic regression model in crude and multivariable adjusted models was used to compare the odds of obesity between urinary sodium tertiles. Results: The findings showed that the mean urinary sodium was not significantly different among overweight, obese, and individuals with normal BMI (P > 0.05) using the crude and multivariable models. Furthermore, no significant difference was observed in the mean BMI according to urinary sodium excretion tertiles. In addition, the analyses showed that the sodium status was not significantly associated with odds of developing obesity in crude and in multivariable adjusted models. Conclusion: No significant relationship was seen between sodium status and overweight or obesity. Future prospective studies are highly recommended to confirm these results.
