Transforming growth factor beta-1 (TGF-ß1) expression in patients with adenomyosis.

Objective: To compare Transforming growth factor beta-1 (TGF-ß1) expression in patients with and without adenomyosis. Methods: A prospective design was performed including 49 patients submitted to hysterectomy. Immunohistochemistry was performed on anatomopathological samples staged in paraffin blocks from patients with and without adenomyosis. The sample contained 28 adenomyosis cases and 21 controls. Student's t-test and multivariate logistic regression tests were used for statistical analysis. Associations were considered significant at p < 0.05. Results: We found no significant association between adenomyosis and: smoking (p = 0.75), miscarriage (p = 0.29), number of previous pregnancies (p = 0.85), curettage (p = 0.81), pelvic pain (p = 0.72) and myoma (p = 0.15). However, we did find a relationship between adenomyosis and abnormal uterine bleeding (AUB) (p = 0.02) and previous cesarean section (p = 0.02). The mean TGF-ß1 intensity (mean ± SD) in the ectopic endometrium of women with adenomyosis showed no significant association (184.17 ± 9.4 vs.184.66 ± 16.08, p = 0.86) from the topic endometrium of women without adenomyosis. Conclusion: TGF-ß1 expression was not increased in the ectopic endometrium of women with adenomyosis.

[Follicle stimulating hormone as predictor of mobile spermatozoa in testicular biopsy of azoospermic patients]. / Hormônio folículo estimulante como preditor do achado de espermatozóides móveis na biópsia testicular de casos de azoospermia.

OBJECTIVE: To define predictive factors of mobile spermatozoa recovery in azoospermic patients. METHODS: Testicular volume, serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and testosterone levels were assessed in 60 azoospermic patients. Patients underwent bilateral testicular biopsy with local anesthesia. Samples were classified according to absence of spermatozoa, presence of motile and nonmotile spermatozoa, and histological findings. Age, hormone levels, testicular volume and histology with motile spermatozoa recovery were compared. P < 0.05 was considered significant. RESULTS: Non-obstructive azoospermia was diagnosed in 45 patients. Significant differences were detected between the group with motile spermatozoa recovery and the group with absence of spermatozoa in terms of FSH levels (P=0.037 ANOVA one-way). A ROC curve was used to define FSH values below 16.05 IU/L (sensitivity: 76.2%, specificity: 67.7%) as predictive factors for motile spermatozoa recovery. Other statistical differences were not detected. CONCLUSIONS: FSH levels below 16.05 IU/L showed good accuracy to predict the presence of motile spermatozoa in the testicular biopsy of azoospermic patients. Physical examination, testosterone levels, LH and prolactin were not useful as predictive factors in the present study.
