RESUMO
Thin endometrium, defined as an endometrial thickness of less than 7 mm during the late follicular phase, is a common cause of frequent cancelation of embryo transfers or recurrent implantation failure during assisted reproductive treatment. Small proteoglycans regulate intracellular signaling cascades by bridging other matrix molecules and tissue elements, affecting cell proliferation, adhesion, migration, and cytokine concentration. The aim of the study is to investigate the role of small leucine-rich proteoglycans in the pathogenesis of thin and thick human endometrium and their differences from normal endometrium in terms of fine structure properties. Normal, thin, and thick endometrial samples were collected, and small leucine-rich proteoglycans (SLRPs), decorin, lumican, biglycan, and fibromodulin immunoreactivities were comparatively analyzed immunohistochemically. The data were compared statistically. Moreover, ultrastructural differences among the groups were evaluated by transmission electron microscopy. The immunoreactivities of decorin, lumican, and biglycan were higher in the thin endometrial glandular epithelium and stroma compared to the normal and thick endometrium (p < .001). Fibromodulin immunoreactivity was also higher in the thin endometrial glandular epithelium than in the normal and thick endometrium (p < .001). However, there was no statistical difference in the stroma among the groups. Ultrastructural features were not profoundly different among cases. Telocytes, however, were not seen in the thin endometrium in contrast to normal and thin endometrial tissues. These findings suggest a possible role of changes in proteoglycan levels in the pathogenesis of thin endometrium.

OBJECTIVE: The aim is to investigate the relationship between thyroid volume measurement and healthy nutrition questionnaire scoring in pregnant women diagnosed with hyperemesis gravidarum (HEG). METHODS: One hundred and fifty pregnant women with a BMI of 15-25 kg/m2 and between the ages of 17 and 42 who were diagnosed with HEG at 11-14 weeks of gestation were included in the study. Patients with a history of any disease, drug use, and previously diagnosed eating disorders were excluded. All patients were subjected to the Healthy Eating Index (HEI) questionnaire. The cutoff value for HEI score was determined as 80 points. Patients were evaluated in two groups: group 1 (HEI <80 score) and group 2 (HEI ≥80 score). Complete urine analysis including ketonuria, and thyroid function tests including TSH, T3, and T4 levels were performed for all patients. In addition, the thyroid gland volume of every patient was measured by the same radiologist. RESULTS: Increased thyroid gland volume was significantly associated with lower TSH levels (p = .02) and lower HEI scores (p < .001). On the other hand, it was not significantly associated with ketonuria (p = .47), and parity status (p = .82). CONCLUSIONS: In our study, we found that there may be an increase in thyroid volume in pregnant women with HEG with lower TSH levels and eating scores. Thyroid volume may predict the patients with probable eating disorders and further studies on thyroid volume in patients with HEG may contribute to the literature.

OBJECTIVE: To investigate the efficacy of new endometriosis biomarkers in diagnosis and treatment. METHODS: Thirty women with Stage III-IV endometriosis who were given an indication for surgery and 49 control patients were compared. Preoperative and postoperative serum levels of Annexin A5 (ANXA5), soluble intercellular adhesion molecule-1 (sICAM-1), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), soluble vascular cell adhesion molecule-1 (sVCAM-1), vascular endothelial growth factors (VEGF) and Ca-125 measurements were compared. RESULTS: AUCs of ANXA5, sICAM-1, IL-6, TNF-α, VCAM-1, VEGF biomarkers were not found to be significant in diagnosing endometriosis when evaluated alone (p > 0.05). Only the AUC of the Ca-125 biomarker values were found to be significant with 73% sensitivity and 98% specificity (p < 0.001). However, when Ca-125 and ANXA5 were evaluated together, it was concluded that the diagnosis of endometriosis could be made with 73% sensitivity and 100% specificity. CONCLUSION: When Ca-125 and ANXA5 are evaluated together, it seems to be more valuable than Ca-125 alone in diagnosing endometriosis.

Objective: To determine the relationship between the cumulative effect of sequential clomiphene citrate (CC) treatments in unexplained infertile women with intercycle and intracycle serum hormone changes. Materials and Methods: Patients who received CC 50 mg in the first cycle (group I, n=34) as ovulation induction and those who received CC 50 mg in the second consecutive cycle (group II, n=18) were compared. Basal (cycle days 2-5) and trigger day (the day that recombinant human chorionic gonadotropin is given) levels of gonadotropin and steroid hormones were measured. Results: The 17OHP increase on trigger day was found to be statistically significantly higher in group II compared to the basal day (p=0.083). The testosterone (T) response on the trigger day of the patients in group II was found to be statistically significantly higher than that in group I (p=0.023). The number of selected follicles was negatively correlated with a follicle-stimulating hormone decrease and positively correlated with an estradiol increase. Endometrial thickness was positively correlated with a luteinizing hormone increase, and cycle cancelation was positively correlated with decreased estradiol. Conclusion: Based on this study, it was concluded that the reason for the increased efficiency rate in successive cycles of CC may be the cumulative increase in T and 17OHP levels. However, this result was found not to affect the clinical pregnancy rate.
RESUMO
AIM: To evaluate the effect of cervical canal features on pain during outpatient hysteroscopy performed by experienced surgeons using mini-hysteroscope. METHODS: A prospective observational study was conducted on 303 women undergoing diagnostic hysteroscopy without anesthesia. Pain intensity was evaluated using the visual analog scale (VAS) when the cervical canal was passed. The patients were divided into two groups according to the VAS score: painless or mild pain (VAS <4) and moderate or severe pain (VAS ≥ 4). The relationship between cervical canal characteristics (length, version, and flexion positions, history of cervical intervention, stenosis, synechiae), obstetric and gynecological history, preoperative anxiety level, procedure duration, and pain intensity was examined. RESULTS: Moderate pain (4 ≤ VAS < 7) was observed in 38% of patients (n = 117) and 14 patients (5%) experienced severe pain (VAS ≥ 7). In multivariate analysis, nulliparity (p = 0.01; OR, 4.6; 95% CI, 1.7-13.2), postmenopausal state (p = 0.02; OR, 2.2; 95% CI, 1.2-4.3), excessive flexion of the cervix and retroverted uterus (p <0.001; OR, 4.1; 95% CI, 2.0-8.5) were identified as risk factors for a painful procedure. Diagnostic hysteroscopy was successful in 98% of the patients. The pain was the primary cause of the failed hysteroscopy. CONCLUSION: In addition to nulliparity and postmenopausal status, unfavorable features of the cervical canal, such as the excessive flexion position of the cervix and uterine retroversion are significant causes of pain during outpatient hysteroscopy.
