Progressive chest radiographic changes in wet lung disease.

Delayed clearance of fetal lung fluid, or wet lung disease (WLD), is a common, well described clinico-radiographic diagnosis. Unusual chest roentgenographic findings in six infants with WLD are reported. All infants had either delayed development of pleural fluid collections or transient apparent worsening of pulmonary parenchymal infiltrates simulating infection. Five of the six patients were treated with antibiotics. The patients were clinically well, radiographically normal, and culture negative by 72 hours. Our findings suggest that worsening of pulmonary parenchymal opacities and the appearance of pleural effusions can be part of the WLD spectrum. An initial radiographic impression of neonatal pneumonia can be changed to WLD and antibiotics stopped after 72 hours if subsequent radiographs show clearing, cultures are negative, and clinical findings resolve as they did in our patients.

Pulmonary hemorrhage associated with systemic lupus erythematosus in children.

Four children with systemic lupus erythematosus (SLE) and pulmonary hemorrhage are discussed. Radiologists should be aware of the possibility of such bleeding when confronted with diffuse parenchymal abnormalities in a child, particularly if there is (a) evidence of unexplained blood loss or (b) signs and symptoms of collagen vascular disease. Pulmonary hemorrhage may occur long before SLE is suspected and appear identical to idiopathic pulmonary hemosiderosis.

Anthropometry of Mexican-American migrant children in northern California.

Anthropometric data were obtained from 209 Mexican-American migrant children, aged 0 to 7 yr, in the Sacramento Valley of California. Hematocrit was measured for 170 children. Only 13 children (7.6%) had hematocrits below acceptable levels. Weight-for-age, height-for-age, and weight-for-height growth percentiles approximated the National Center for Health Statistics standards. Only 15% of the children were at or below the 10th percentile of height-for-age, and only 7% were above the 95th percentile of weight-for-height, in contrast to earlier studies of Mexican-American children. The mean percentile of weight-for-height increased significantly with age, while height-for-age decreased. The rate of growth in weight and height accelerated during their summer residence in the US, indicating that the adequate growth status of these children may be related to improved conditions for growth while in the US.

Bilateral fat necrosis of the scrotum.

The typical patient with fat necrosis of the scrotum is a prepuberal heavy set male subject who has extratesticular scrotal masses, usually bilateral, with mild to moderate pain but no systemic complaints or symptons related to voiding. The masses are firm, tender and do not transmit light. With a firm diagnosis expectant treatment will allow spontaneous resolution of the lesions. If doubt exists appropriate surgical intervention is advocated. Hypothermic injury, such as swimming in frigid water, is the most probable etiologic agent.

Recurrent subtemporal epidural hematoma with second, third and fourth cranial nerve compression.

A patient who was admitted with visual loss and, third and fourth cranial nerve paresis as only evidence of a recurrent epidural hematoma is presented. A review of some of the mechanisms suggested in the literature to explain the etiology of ocular signs in the presence of extracerebral collections is offered. We propose an additional possible mechanism and review the anatomical explanation for the development of these symptoms.
