Objective: Progestins are used as an alternative to gonadotropin releasing hormone (GnRH) antagonists to suppress premature luteinizing hormone (LH) surge and a flexible protocol has been defined recently. The aim of this study was to compare the efficacy of flexible protocols with dydrogesterone and GnRH antagonist in suppressing LH surge. Material and Methods: This retrospective, case-control study, was conducted in an infertility unit of a tertiary university hospital. A daily dose of 40 mg dydrogesterone was compared with GnRH antagonist (GnRHant) in controlled ovarian hyperstimulation cycles between July 2018 and July 2019. Dydrogesterone was started when the leading follicle was 12 mm or serum estradiol was over 300 pg/mL. A subgroup analysis of poor responder patients was also performed. Results: In total there were 105 subjects aged between 23 and 41 years, 52 in the dydrogesterone group and 53 in the GnRHant group. Duration of pituitary suppression was longer in dydrogesterone group. Premature ovulation was observed in 11.5% (6/52) and 0% in the dydrogesterone and GnRHant groups, respectively. However, collected oocyte counts and metaphase II oocyte counts were found to be similar between the groups. The six patients with premature ovulation were in poor responder subgroup. Conclusion: Dydrogesterone can be used as an alternative to antagonist regimen in patients where embryo transfer is not planned in the same cycle. However, flexible regimen may not be appropriate in patients with diminished ovarian reserve, as advanced follicular maturation and delayed suppressive effect of oral progesterone may cause premature ovulation. Randomized controlled trials in particular patient groups are required to determine the most effective minimum dose and time of application to ensure treatment success.
OBJECTIVE: Reperfusion injury occurs when the condition causing ischemia in ovarian torsion is corrected and the blood supply is re-established. The aim of this study is to evaluate whether doxycycline treatment reduces reperfusion injury in a rat model. STUDY DESIGN:Thirty-five female albino Wistar rats were split into the five groups. Sham: Sham operation; ischemia (I): 2 hours of ischemia; ischemia and reperfusion (I/R): 2 hours of ischemia followed by 2 hours of reperfusion; Sham-Dc: Sham operation and doxycycline 10-mg/kg (2 hours prior to surgery); I/R-Dc: 2-hours of ischemia and doxycycline 10-mg/kg and 2-hours of reperfusion. The groups were compared in terms of histological and biochemical features. A semi-quantitative histological assessment scoring system was used for the histological examination. Follicular cell degeneration, vascular congestion, haemorrhage, and inflammatory cell count were evaluated for histological analysis. For biochemical analysis of reperfusion injury, the body's total antioxidant status and total oxidant status were measured using a fully automatic method. The oxidative stress index was calculated by dividing total antioxidant status by total oxidant status. RESULTS:In the sham group the ovaries were histologically normal. Oedema, vascular congestion, bleeding, leukocyte infiltration, and follicle degeneration were increased in other groups (p<0.05). There was less leukocyte infiltration in the I/R-Dc group compared to I/R group. Other histological features were similar in these groups. Doxycycline increased the malondialdehyde, total antioxidant and total oxidant status levels in Sham-Dc and I/R-Dc groups. This increase was statistically significant between Sham and Sham-Dc groups. However, although there was an increase in the biochemical markers in the I/R-Dc group, this increase was not significant compared to I/R group. CONCLUSION: Doxycycline treatment in ovarian torsion does not reduce I/R injury. Doxycycline may even increase reperfusion injury, according to biochemical findings.
Objective: To assess the quality of information presented in YouTube videos about human papillomavirus vaccination. Method: The descriptive study was conducted at Konya Meram Education and Research Hospital, On October 15, 2019 when the YouTube website was search using the terms ‘human papillomavirus’, ‘HPV vaccine’ and ‘Gardasil’. The videos were recorded to a playlist by two individual gynaecologists to prevent any change in the listed videos. The videos were categorised into 3 groups; useful information group A, misleading information group B and insufficient information group C. The quality of the videos was scored using global quality scale from 1 = poor quality to 5 = excellent quality. DISCERN scale was used for reliability. A 10-point scale was used to evaluate comprehensiveness of the videos. Data was analysed using SPSS 20. Results: Of the 200 videos assessed, 179(89.5%) were analysed. There were 17(9.5%) videos in group A, 38(21.2%) in group B and 124(69.3%) in group C. Mean global quality scale score was 3.94±1.39 group A, 1.84±0.59 group B and 3.13±0.94 group C (p<0.001). Mean reliability values were 4.18±1.13group A, 1.66±0.66 group B and 3.03±0.87 group C (p<0.001). Comprehensiveness scores were 6.94±2.49 group A, 1.53±0.95 group B and 4.87±1.72 group C (p<0.001). Conclusion: Professional organisations, university channels and doctors should provide accurate, unbiased and evidence-based information on YouTube for community awareness. Key Words: HPV vaccine, Health information on YouTube, e-health, Health communication.
