Familial occurrence of congenital pulmonary lymphangiectasis. Genetic implications.

Congenital pulmonary lymphangiectasis (CPL) is a rare, generalized disease of the lung, consisting of lymphatic cysts in the subpleural and interlobular connective tissue. This disorder typically manifests a clinical picture of acute respiratory distress with cyanosis shortly after birth, with death occurring in the neonatal period. Several cases of this disorder have been described in the literature, but there has been no family with more than one affected child. We report the first instance, to our knowledge, of familial cases of CPL, which raises an important question regarding a possible genetic component in this disorder. The implications of this are discussed.

Hepatocellular adenoma in a young woman with beta-thalassemia and secondary iron overload.

The occurrence of a hepatocellular adenoma is described in a young woman with beta-thalassemia and secondary iron overload. This patient had no history of oral contraceptive use, and in fact was hypogonadal as a result of iron deposition in pituitary and gonadal tissue. Although hepatocellular carcinoma frequently occurs in diseases associated with iron overload, this is the first report of a benign liver tumor associated with secondary iron overload.

Omphalocele in half-siblings.

A family is described in which half-siblings, a boy and a girl born to unrelated mothers and a phenotypically normal father, were affected with omphalocele. The suggested mode of transmission remains unclear. Prenatal diagnosis to detect an affected fetus should be offered to relatives of omphalocele-affected individuals.

Malakoplakia of the brain. A report of two cases occurring in childhood.

Malakoplakia was found in the brain biopsy specimens of two children with meningoencephalitis probably due to herpes simplex. Histologically, there was extensive parenchymal destruction and cellular infiltration. Numerous von Hansemann histiocytes and typical Michaelis-Gutmann bodies were present. Ultrastructurally these bodies had a dense central core and concentric alternating rings. Large intracytoplasmic phagolysosomes were present. Malakoplakia most frequently involves the urinary tract of adults. Only a few children with malakoplakia have been described. There are two previous reports of cerebral malakoplakia associated with neonatal herpes simplex. The pathogenesis is obscure. Several reports suggest an altered histiocytic response to a bacterial agent as the pathogenetic mechanism. Our findings raise the possibility of an etiologic role of a virus, such as herpes simplex.

Focal glomerulosclerosis in children: correlation of histology with prognosis.

The clinical and pathologic data of 32 nephrotic children diagnosed as having focal glomerulosclerosis were retrospectively analyzed to determine what factors were responsible for progression to renal failure in 12 of these children. The patients were classified into three groups based on the histologic findings in their initial renal biopsies: Group I (n = 19) had a combination of global and segmental lesions; Group II (n = 8) had only globally sclerotic or obsolescent glomeruli; and Group III (n = 5) had only segmentally sclerosed glomeruli. Ten of the 12 patients with end-stage renal failure came from Group I and two from Group II. The median period from recognition of symptoms to renal failure was four years. Clinical features were of little prognostic value. However, comparison of the histopathologic data of the ten patients in Group I with renal failure (Group Ia) and Groups Ib, II, and III revealed that the risk of progressing to renal failure was significantly higher in patients having greater than 20% of their glomeruli involved by both global and segmental lesions (P = 0.005). Furthermore, patients in Group I and III had a lower probability of responding to treatment as compared to patients in Group II (P less than 0.025).

Acute radiation nephritis. Light and electron microscopic observations.

Light and electron microscopy were used to observe acute radiation nephritis. By light microscopy the changes were of fibrinoid necrosis of the arteries and atrerioles with segmental necrosis of the glomerular tufts. By electron microscopy the endocapillary cells reacted by hypertrophy and hyperplasia with increase in cytoplasmic organelles. In addition, disruption of endothelial and epithelial cells from the basement membranes were seen. It is concluded that the electron microscopic changes were unique and may be helpful in differentiating the necrotizing glomerulitis seen in other conditions, especially malignant hypertension.
