Controversy and Consensus on Indications for Sperm DNA Fragmentation Testing in Male Infertility: A Global Survey, Current Guidelines, and Expert Recommendations

Purpose: Sperm DNA fragmentation (SDF) testing was recently added to the sixth edition of the World Health Organization laboratory manual for the examination and processing of human semen. Many conditions and risk factors have been associated with elevated SDF; therefore, it is important to identify the population of infertile men who might benefit from this test. The purpose of this study was to investigate global practices related to indications for SDF testing, compare the relevant professional society guideline recommendations, and provide expert recommendations. Materials and Methods: Clinicians managing male infertility were invited to take part in a global online survey on SDF clinical practices. This was conducted following the CHERRIES checklist criteria. The responses were compared to professional society guideline recommendations related to SDF and the appropriate available evidence. Expert recommendations on indications for SDF testing were then formulated, and the Delphi method was used to reach consensus. Results: The survey was completed by 436 experts from 55 countries. Almost 75% of respondents test for SDF in all or some men with unexplained or idiopathic infertility, 39% order it routinely in the work-up of recurrent pregnancy loss (RPL), and 62.2% investigate SDF in smokers. While 47% of reproductive urologists test SDF to support the decision for varicocele repair surgery when conventional semen parameters are normal, significantly fewer general urologists (23%; p=0.008) do the same. Nearly 70% would assess SDF before assisted reproductive technologies (ART), either always or for certain conditions. Recurrent ART failure is a common indication for SDF testing. Very few society recommendations were found regarding SDF testing. Conclusions: This article presents the largest global survey on the indications for SDF testing in infertile men, and demonstrates diverse practices. Furthermore, it highlights the paucity of professional society guideline recommendations. Expert recommendations are proposed to help guide clinicians

An unusual cause of atrial fibrillation: Exposure to insecticides

Background Although there are many well-known cardiac results of insecticide poisoning, atrial fibrillation (AF) has not been reported as the result of insecticide intoxication

Is inguinal hernia a risk factor for varicocele in the young male population?

Objectives: The aim of this study is to investigate the role of the inguinal hernia over the development of varicocele, in cases with accompanying inguinal hernia. Methods: The continuous variables were calculated from mean and standard deviation, and intermittent variables were calculated over percentage and frequency. Normality testing was performed on continuous variables using the Kolmogorov-Smirnov test. Univariate analyses were performed using the unpaired Mann-Whitney U test and Chi-squared test was used for proportions. Kendall's tau-b correlation coefficient was used for correlition coefficient. Logistic regression modeling were used to identify the impact of inguinal hernias on selected cases. The data were analyzed with SPSS™ for Windows 22 (SPSS,Chicago, IL). Results: Twelve cases (23.1%) in the inguinal hernia group also had varicocele, which was relatively high, whereas 12 cases with inguinal hernia in the varicocele group corresponded to only were 4.02% (12/52 (23.1%) vs 12/298 (4.02%) ). On the other hand, as a result of the binary logistic regression, we found statistically significant difference in the probability of being diagnosed varicocele among the patients with inguinal hernia as 1.94 times. Conclusions: We think that in addition to the direct compression of some of the inguinal hernias on testicular veins, the potential for a combination of common enzymatic and biochemical disorders in some of the cases involving these two disorders may be play role

CLINICAL EFFICACY OF DEXAMETHASONE FOR ACUTE EXUDATIVE PHARYNGITIS

The objective of this study was to investigate whether treatment with single-dose dexamethasone can provide relief of symptoms in acute exudative pharyngitis. A prospective, randomized, double-blinded, placebo-controlled clinical trial was undertaken over a 3-month period in a university-based Emergency Department. The study included all consecutive patients between 18 and 65 years of age presenting with acute exudative pharyngitis, sore throat, odynophagia, or a combination, and with more than two Centor criteria. Each patient was empirically treated with azithromycin and paracetamol for 3 days. The effects of placebo and a fixed single dose (8 mg) of intramuscular injection of dexamethasone were compared. The patients were asked to report the exact time to onset of pain relief and time to complete relief of pain. After completion of the treatment, telephone follow-up regarding the relief of pain was conducted. A total of 103 patients were enrolled. Thirty patients with a history of recent antibiotic use, pregnancy, those who were elderly (> 65 years of age) and patients who failed to give informed consent were excluded. Forty-two patients were assigned to the placebo group and 31 were assigned to the intramuscular dexamethasone group (8-mg single dose). Time to perceived onset of pain relief was 8.06 +/- 4.86 h in steroid-treated patients, as opposed to 19.90 +/- 9.39 h in the control group (p = 0.000). The interval required to become pain-free was 28.97 +/- 12.00 h in the dexamethasone group, vs. 53.74 +/- 16.23 h in the placebo group (p = 0.000). No significant difference was observed in vital signs between the regimens. No side effects and no new complaints attributable to the dexamethasone and azithromycin were observed. Sore throat and odynophagia in patients with acute exudative pharyngitis may respond better to treatment with an 8-mg single dose of intramuscular dexamethasone accompanied by an antibiotic regimen than to antibiotics alone.
