Pediatric hypertrophic gastropathy.

Four previously healthy children presented in a 6-week period with marked hypoproteinemia without liver disease, malnutrition, or significant proteinuria. They all had strikingly similar radiographic findings consisting of enlarged folds confined to the fundus and body of the stomach. Three of the children had prodromal symptoms suggesting a viral illness.

Sonography in the diagnosis and management of hepatic amebic abscess in children.

Hepatic amebic abscess is a potentially fatal infection which is difficult to diagnose in children. Sonography is an ideal non-invasive imaging tool which can prove invaluable in the diagnosis and management of hepatic amebic abscess. Sonographic findings should suggest the correct diagnosis in most instances.

Amebiasis: unusual radiographic manifestations.

Unusual radiographic manifestations of amebiasis have not previously been emphasized in the literature. These unusual manifestations often mimic other, more common disease entities. A recent case of urinary bladder-cervical amebiasis prompted a review of other unusual manifestations of amebiasis.

A mixed hamartoma of the liver: light and electron microscopy.

The gross, microscopic, and ultrastructural features of a mixed liver hamartoma occurring in a three month old infant are reported. The differentiation from two solid liver masses, focal nodular hyperplasia and liver cell adenoma is emphasized. Mesenchymal hamartomas, though usually cystic rather than solid masses, share the histologic feature of fibroductular tissue with mixed liver hamartomas and focal nodular hyperplasia.

Collaborative study of the effects of human growth hormone in growth hormone deficiency: IV. Treatment with low doses of human growth hormone based on body weight.

In order to define the minimum effective dose of human growth hormone (GH) in growth hormone deficient children, GH was administered to three groups of patients based on their body weight. Five children who received 0.01 International Unit (IU) GH/kg three times a week (tiw) failed to respond with a significant increase in their rate of growth.

Cholelithiasis and cholecystitis in childhood.

Six cases of cholecystitis and cholelithiasis confirmed by x-ray examination and surgical operation were observed in a ten-year period. Due to the wide variability in signs and symptoms in children, cholecystitis and cholelithiasis can be diagnosed only with a high degree of clinical suspicion and roentgenological examination. Gallbladder disease is uncommon in childhood but should be considered in children with vague abdominal pains or bouts of unexplained jaundice.

Radiographic diagnosis of intestinal perforation in early infancy.

Records of 25 patients with intestinal perforation in early infancy who were treated at the Los Angeles County General Hospital in a period of 15 years were reviewed. Sixteen had roentgen evidence of pneumoperitoneum, and nine did not. The mortality rate was 94 per cent in the group with pneumoperitoneum, 78 per cent in the other, and 88 per cent overall.
