RESUMO

BACKGROUND: There is no satisfactory explanation why some individuals experience severe attacks of asthma, yet others, exposed to similar stimuli, have a milder form of the disease. OBJECTIVE: We tested the hypothesis that children with more severe disease may have relative adrenal insufficiency compared to the children with milder disease. PATIENTS AND METHODS: Sixteen children with chronic asthma aged 8-16 years old were studied. Adrenal function was evaluated by the 24-h excretion of urinary free cortisol (UFC) before and after ACTH stimulation, and by plasma cortisol levels before and 60 min after ACTH administration. The severity of bronchial hyperresponsiveness was evaluated by the methacholine provocation test. RESULTS: Nine children had 20% fall in forced expiratory volume in 1 sec (FEV1) after a provocative concentration (PC20FEV1) of methacholine > or =2.5 mg/ml and were considered as having mild-moderate bronchial hyperresponsiveness (Group A). Seven children had a PC20FEV1 of < or =1.25 mg/ml and were considered as having severe bronchial hyperresponsiveness (Group B). No significant difference was found between the peak plasma cortisol response to ACTH between the two groups (634+/-182 and 586+/-137 nmol/l, respectively). However, there was a significant statistical difference (p <0.01) in the 24-h UFC response to ACTH between the children from Group A (345+/-107 nmol/m2 ) and the children from Group B (161+/-125 nmol/m2). CONCLUSIONS: Based on the low levels of 24-h UFC secretion in severely asthmatic children in our study, we propose the encouragement of provision of a short course of inhaled steroids to be kept at home for the emergency therapy of those children identified as having high-risk asthma.

RESUMO

OBJECTIVE: To examine the effect of dopamine agonist (DA) treatment on clinical and biochemical features in hirsute, hyperprolactinemic (HPRL) women and the relationship between prolactin (PRL) and androgens. STUDY DESIGN: We evaluated 80 hirsute HPRL women (age, 27 +/- 1 years [mean +/- SE]) with neuroleptic treatment, prolactinoma and idiopathic HPRL (12, 13 and 55, respectively). DA, mainly bromocriptine, was administered for 11 +/- 1 months. Response indicators were Ferriman-Gallwey hirsutism (FGS) and Leeds acne (LAS) scores, circulating PRL, dehydroepiandrosterone sulfate (DHEAS), free and total testosterone, and androstenedione. RESULTS: Baseline PRL correlated positively with DHEAS (r = .23, P = .03) and free testosterone (r = .36, P < .001). In all women, FGS, LAS, PRL, free testosterone, DHEAS and androstenedione decreased by 40-85% during DA treatment (P < .001). The decline in free testosterone was higher when PRL was > or = 65 ng/mL than when PRL was < 65 (P = .03) and correlated positively with basal DHEAS (r = .40, P < .001). CONCLUSION: Our data suggest a modulation by PRL of adrenal androgen production. DA treatment reduces PRL and serum androgens. It results in a significant clinical improvement in acne and hirsutism. Therefore, DA is recommended as monotherapy for hyperandrogenic.

RESUMO

There is no consensus concerning optimal adnexal surgery during abdominal hysterectomy, when continued hormonal function is desired, associated with reduced sequelae in the future. The aim of the study was to compare residual ovarian function following abdominal hysterectomy with preservation of one or both ovaries, in a prospective randomized study. Forty patients were allocated randomly and sequentially into two groups: those undergoing abdominal hysterectomy with unilateral oophorectomy, and those undergoing abdominal hysterectomy only. Ovarian function was evaluated by measuring FSH, TLH and E2 before, and 1 week, 1 month, 3 months and 6 months after the operation. Thirty-five percent of the patients undergoing abdominal hysterectomy with unilateral oophorectomy demonstrated impaired ovarian function 6 months after the operation. None of the patients with both preserved ovaries showed impaired ovarian function 6 months later. Therefore, when continued ovarian function following abdominal hysterectomy is desired, preservation of both ovaries seems to be more beneficial.
