Background and Objectives: Osteoporosis is a common disease of the skeletal system that increases the risk of fracture. The prevalence of osteoporosis has been increasing as the aging population increases, affecting more than 200 million people worldwide. This study aimed to shed light on the clinical impact of osteoporosis on women’s health and quality of life by evaluating the prevalence and risk factors for this disease among postmenopausal women, using a 10-year dataset from a tertiary center. Materials and Methods: This retrospective cohort study was conducted at Dokuz Eylül University, Department of Obstetrics and Gynecology, between 2010 and 2022. A total of 3289 postmenopausal women aged 50–60 years who were undergoing routine gynecological checkups were included in the study. Patients with a prior diagnosis, a history of medical conditions, or who were taking medications affecting bone mineral density (BMD) were excluded. Data on demographics, smoking status, diabetes status, body mass index (BMI), parity, and fracture history were collected. BMD scores were classified as normal, osteopenia, or osteoporosis. Results: The prevalence of osteoporosis was 10.4%. The median age of the patients was 56.0 years. Smoking, diabetes, and a history of bone fractures were found to significantly increase the risk of osteoporosis. BMI was found to have a protective effect against osteoporosis. According to multivariate analysis, the risk of osteoporosis increased by 2.46 times in patients who smoke, 3.78 times in patients with diabetes, and 6.23 times in patients with a history of fractures. Conclusions: Awareness of modifiable risk factors such as smoking is crucial for preventing osteoporosis-related complications. Diabetes, even when it is not complicated, increases the risk of osteoporosis. Physical exercise, calcium, and vitamin D intake are important, especially during young adulthood, as they are the primary contributors to peak bone mass. Because neck fractures are more common in patients with osteopenia, early diagnosis and routine screening can mitigate future complications.

Objectives: This study aimed to predict the diagnosis of adenomyosis by revised definitions of morphological uterus sonographic assessment (MUSA) features in individuals who had hysterectomy.Methods: This was retrospective cohort research conducted at a tertiary facility. Between January 2022 and January 2023, 196 individuals who had hysterectomy were analyzed in the research. The revised definitions of MUSA features of the adenomyosis approach were used to record the direct and indirect results of the sonography. The cases were classified as Group 1 (adenomyosis; n = 40, 20.4%) and Group 2 (control; n = 156, 79.6%) according to histopathology reports.Results: Hyperechogenic islands and echogenic subendometrial buds and lines were the most predictive direct features (p = 0.02). Globular uterus and irregular junctional zone were the most predictive indirect features (p = 0.04; p = 0.03, respectively). Among all indirect features, the globular uterus was the most predictive (p = 0.02). Total feature >4 was determined as the significant cutoff value to predict adenomyosis (p < 0.001).Conclusion: This study shows that combinations with a total number of features >4 can be practically used in the evaluation of adenomyosis using the revised definitions of MUSA features.

Transverse vaginal septum is a rare type of mullerian anomaly resulting from failure of the canalization of the vaginal plate at the point where the urogenital sinus meets the mullerian duct and usually presents at menarche with symptoms of outflow tract obstruction. Instead, patients with a perforated septum often have normal menses and usually present with difficulties with intercourse or infertility. A 24-year-old patient with 5 years of infertility is reported. Following assessment, isolated microperforated transverse vaginal septum (U0C0V3 according to the new classification system of the European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy for congenital uterine anomalies) was detected with no additional urogenital anomaly and simple excision of the septum and end-to-end vaginal anastomosis was performed. The patient became pregnant spontaneously 2 months after the operation when sexual intercourse was permitted. Transverse vaginal septum, which presented itself with no clinical findings and only primary infertility, is discussed with a review of the existing literature.

Background: The pathogenesis of endometriosis is still debatable, and many studies reported a predisposition to infectious and immunological factors. In this study, we aimed to evaluate the human papillomavirus (HPV) positivity in endometriosis pain-related symptoms and infertility. Methods: In this cross-sectional study, 410 endometriosis patients were enrolled in this study. HPV-positive (n = 202) and HPV-negative (n = 208) patients compared with pain-related symptoms, infertility, and endometrioma presence. The term “Other HPV” was utilized to encompass all HPV types with the exception of HPV 16 and 18, which were specifically identified as HPV 16/18. Results: Dyspareunia in the “Other HPV”-positive group (12.8 %) was statistically higher than in the HPV-negative group (4.8%; p = 0.007). The infertility rate was significantly higher in the HPV 16/18 positive group (high-risk HPV) 35.8% than in the HPV-negative (7.6%), and “Other HPV” positive group (8%; p < 0.001). Endometriosis-related pain symptoms were significantly higher in high-risk HPV (49%) than in the HPV-negative (37%), and “Other HPV” positive group (46.3%; p = 0.046). The ovarian endometrioma rate was slightly higher in group HPV 16/18 positive population (16.9%) than in “Other HPV” types positive (11.4%), and HPV-negative groups (7.2%; p = 0.08). Conclusions: Our results could provide a potential predisposing role of HPV infection in pain in endometriosis clinics and infertility. Moreover, HPV subtypes may have a different impact on clinical conditions.

Background/aim: To evaluate the relationship between the change in pain intensity over days in the menstrual-cycle and cognitive functions in females having primary dysmenorrhea.Materials and Methods: One hundred thirty-four females with primary dysmenorrhea who were admitted to our hospital from January 2021 to November 2023 were assessed. Of these participants, 46 individuals who subjectively stated that their cognitive functions were affected, for whom neurology consultation was requested, and for whom patient data were available, were included in the study.Results: Significant decrease was seen in phonemic fluency and semantic fluency in patients who were evaluated on the 3rd day of menstrual follow-up (p<0.001-and-p<0.001, respectively). Significant decrease was observed in forward-digit span and backward-digit-span scores in patients who were evaluated on the 3rd day of menstrual follow-up (p< 0.001 and p< 0.001, respectively). A significant decrease was seen in forward-digit-span and backward-digit-span scores in patients who were evaluated on the most painful day of menstrual follow-up (p< 0.001 and p< 0.001, -respectively). Significant decrease in logical memory subtest WMS-R in patients who were evaluated on the most painful day of menstrual follow-up (p< 0.001).Conclusion: Consistent with the literature, we found strong evidence showing a negative correlation between dysmenorrhea and cognitive function. Future prospective, larger sample-size studies comparing cognitive function in females with and without dysmenorrhea at various stages of the menstrual-cycle are needed.
