RESUMO

OBJECTIVE: To study Ferriman-Gallwey (FG) scoring in adolescents with an aim to correlate these scores with serum androgens and mullerian inhibiting substance (MIS). DESIGN: Cross sectional study. SETTING: Pediatric and Adolescent Gynecology Clinic of a university hospital. PATIENTS: Twenty-four hirsute adolescent girls age 12-19 with a FG score of 6 or greater. INTERVENTIONS: FG examination and collection of serum levels of MIS, total testosterone, free testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin, cortisol, and androstenedione. MAIN OUTCOME MEASURES: Correlation between FG scores in adolescents and serum androgens and MIS. RESULTS: Weak correlations were seen between FG score and FSH, free-testosterone, total testosterone, and cortisol. Increasing FG scores correlated with an increase in cortisol. As FG score increased, FSH, free-testosterone, and total testosterone decreased. There was no statistical relationship between FG score and LH, androstenedione, prolactin, and MIS. There were weak positive correlations between MIS levels and FSH, total testosterone, and androstenedione. There was no evidence for a linear relationship between MIS levels and LH, free testosterone, cortisol, prolactin, and FG score. CONCLUSIONS: The utility of FG scoring in adolescents is unknown. There were no direct correlations found with MIS levels and FG score. MIS was not found to be a predictor of hirsutism. A larger study is needed to assess the clinical relevance of FG scoring and presence of underlying causes of hirsutism in adolescents.

RESUMO

OBJECTIVE: Interleukin-2 (IL-2) induces protein leakage from the microcirculation and activates lymphocytes; yet it is unclear how it alters endothelial barrier function. Here, we report of a new continuous monitoring system that allows for the continuous measurement and correlation of endothelial calcium, permeability to albumin, and extravasation of lymphocytes. METHODS: IL-2 activated lymphocytes (IL-2 LYMPH) or unstimulated lymphocytes (LYMPH) were co-incubated with human microvascular endothelial cells (HMVEC). Endothelial albumin permeability, lymphocyte extravasation intracellular calcium mobilization, and f-actin distribution were examined using a new continuous monitoring system. RESULTS: The clearance rate of fluorescein isothiocyanate-labeled-human serum albumin (FITC-HSA) in the presence of IL-2 LYMPH peaked at 20 minutes, whereas the clearance rate of LYMPH peaked at 40 minutes. Approximately 40 minutes after the peak in the clearance rate to albumin, extravasation of carboxyfluorescein-labeled lymphocytes was detected. Peak clearance rates for the extravasation of IL-2 LYMPH occurred at approximately 40 minutes after the addition of the lymphocytes to the HMVEC, whereas the peak clearance rate for the LYMPH occurred at 60 minutes after their addition. Both FITC-HSA and lymphocyte extravasation were measured concurrent to endothelial intracellular calcium mobilization by FURA-2. There was an increase in calcium activation after the addition of IL-2 stimulated lymphocytes (71 +/- 5.1 nmol/L to 185 +/- 18.9 nmol/L) compared with unstimulated lymphocytes (71 +/- 5.1 nmol/L to 110 +/- 12.2 nmol/L). The addition of IL-2 had little or no effect on endothelial actin, whereas the unstimulated lymphocytes and, to a greater extent, IL-2 LYMPH increased the presence of transversing stress fibers and decreased peripheral actin. CONCLUSIONS: The findings reported here suggest that the permeability and extravasation events that occur upon addition of lymphocytes proceeds by a calcium- and actin-dependent mechanism and that incubation of lymphocytes with IL-2 enhances normal lymphocyte mechanisms of extravasation.
