Prediction of protein structures continues to be a difficult problem, particularly when there are no solved structures for homologous proteins to use as templates. Local structure prediction (secondary structure and burial) is fairly reliable, but does not provide enough information to produce complete three-dimensional structures. Residue-residue contact(More)
The systemic manifestations of "asphyxia" were evaluated prospectively in 35 consecutively intubated term newborn infants. The following systemic organ injuries were identified most often: (1) renal, ie, oliguria less than 1 mL/kg per hour for at lest 24 hours (40%), an elevated urinary beta-2-microglobulin concentration (57%), azotemia (11%), and an(More)
Controversy exists concerning the degree of importance of periventricular intraparenchymal echodensities (IPE) observed on neonatal ultrasound scans in the determination of subsequent neurologic disability in premature infants. In this report, IPE was studied in 75 infants weighing less than 2,000 g at birth to determine the basic characteristics of the(More)
Characteristic radiographic findings of absence of the left pericardium were observed in two relatives who were related to two other individuals with different types of congenital heart defects. Familial occurrence of congenital absence of pericardium has not been reported previously. The strong male sex predilection in the previously reported patients, the(More)
Antral webs and diaphragms are considered a rare cause of gastric outlet obstruction in infants and children. A radiographic diagnosis of antral web was made in 28 children during a 26-mo period. Nonbilious, often projectile vomiting was the predominant presenting symptom in 24 infants who were less than 6 mo of age. The older children complained of pain,(More)
In a 3-yr period, eight infants among 43 survivors of acute NEC developed intestinal stricture. Four infants developed multiple stricture after proximal diversion procedures, and four had single strictures after medical therapy. Nineteen cases of intestinal stricture after NEC were collected from the literature. Radiographic examinations at the time of the(More)
Twenty-two patients with Henoch-Schonlein syndrome are reviewed, and four unusual cases are reported in detail. Henoch-Schonlein syndrome represents a diagnostic problem when abdominal manifestations precede cutaneous lesions and suggest a surgical abdomen. Unusual radiographic features such as changes in the small bowel identical to Crohn disease or(More)
