Comparison of ultrasound with plain radiography and CT for the detection of mediastinal lymphadenopathy in children with tuberculosis.

Background: Lymphadenopathy, with or without parenchymal abnormality, is the radiological hallmark of primary tuberculosis (TB) in children. However, lymph node enlargement may pass undetected on plain chest radiographs. Ultrasonography provides complementary information to that obtained by radiographs.

Neonatal hyperthyroidism in infants of mothers previously thyroidectomized due to Graves' disease.

Neonatal hyperthyroidism generally arises as a result of active maternal Graves' disease via transplacental passage of thyroid stimulating immunoglobulins (TSI). On occasions, production of these antibodies may continue after thyroid ablation, either surgically or with radioiodine therapy. We present data concerning three patients (two of them twins) whose mothers had previously undergone near-total thyroidectomy prior to conception.

[Randomized multi-center trial of the administration of erythropoietin in anemia of prematurity].

Objectives: The purpose of this study was to test the therapeutic effect of human recombinant erythropoietin (rH-EPO) on anemia of prematurity.

Material And Methods: Fifty-eight preterm infants less than 34 weeks of gestational age from three different hospitals were studied. Transfusional policies were similar in all three centers.

[Perinatal factors predicting hypoxic-ischemic encephalopathy in asphyxic newborn infants].

Between 1 May 1984 and 30 April 1985, 1,354 term or posterm neonates being white and having asphyxia in controlled delivery were studied to predict development of neurological signs and its seriousness. In each case correlations were estimated between the existence of neurological signs and its grade and 100 gestational, obstetric and neonatal factors of potential predictor. The discriminatory analysis indicated that the more significants predictors were: Apgar at five minutes, prolonged labor, twins, resuscitation, DIP I, cephalhematoma, caput succedaneum, umbilical artery pH, urgent cesarean section, hemorrhagic amniotic fluid, gestational edema, variable DIP, high forceps.
