RESUMO
Recurrent pneumothorax is a rare neonatal condition and there are few cases reporting surgical treatment, mainly based on adult studies. We present a male, term newborn that after four recurrent spontaneous pneumothorax (treated with pleural needle aspiration and drains) underwent thoracoscopic mechanical pleural abrasion. There were no post-operatory complications and no recurrence reported until the second year of life. We believe that this technique is safe and effective and may play an important role in these cases.
RESUMO
INTRODUCTION: Cardiac ultrasounds (US) are not always available at the bedside. Cardiac Troponin I (cTnI), CK-MB and NT-proBNP may be an alternative or complementary to influence evaluation and treatment. OBJECTIVES: To determine reference ranges of biochemical markers cTnI, CK-MB and NT-proBNP in normal neonates. METHODOLOGY: Cord and blood samples were collected from neonates and the above biochemical markers were determined. Ultrasounds were performed blindly. RESULTS: CK-MB remains constant from cord blood to the first day, declining thereafter to almost half the values (81.5 vs 52.0 U/l); cTnI increases from 0.004 to 0.058 ng/ml by 72 h falling to 0.030 by day 10; NT-proBNP peaks by 24 h (5085.5 pg/ml), subsiding to 3388.5 pg/ml by day 3, falling to 1316.0 pg/ml by day 10. CONCLUSIONS: CK-MB, mostly of muscle origin and reflecting labor stress or injury, is not to recommend as a measure of myocardial damage in the neonate. The rise in cTnI may be explained by a degree of myocardial involvement, albeit physiological. The initial rise and subsequent fall of NT-proBNP represents the physiological ventricular overload of transient birth adaptation.

Säo revisados os achados clínicos e patológicos em 94 espécimes obtidos por salpingectomias que foram realizadas em dois hospitais, no período de julho de 1975 a dezembro de 1981. Trompas uterinas normais foram encontradas em 47,6% dos espécimes coletados de clínicas privadas. Gravidez tubária (32,7%) e doença inflamatória crônica (28,9%) foram verificadas nos espécimes do Hospital Universitário. Presume-se que a alta percentagem de espécimes normais na clínica privada seja o resultado de cirurgias para esterilizaçäo
