[Clinical and histopathologic polymorphism in cystic fibrosis].

After reviewing recent data concerning the pathologic physiology of cystic fibrosis the authors present an anatomoclinical study of 30 infants, of which 13 neonates, with a diagnosis of mucoviscidosiss, emphasizing the clinical and pathohistologic polymorphism of this affection, and, particularly involvement of the liver and intestines. Specific hepatic lesions were encountered in only 10% of the group studied (Bodian biliary cirrhosis and mucus stoppers in the bile ducts). Unspecific hepatic lesions were dominant, common with those of neonatal hepatitis, and hepatic steatosis.

Congenital hemihypertrophy. Tendency to association with other abnormalities and/or tumors.

Nine cases of congenital hemihypertrophy of an entire half of the body ("true" hemihypertrophy) were investigated in relation to literature data. The left side was more often affected (7:2) and the abnormality was more frequent in females (5:4). Associated abnormalities were present in all cases: a single abnormality in 3 cases (mental retardation, iris heterochromia and, respectively, left foot gigantism) and 3 to 13 abnormalities in the other 6 cases.

Uncommon pneumonia associated with acute poststreptococcal glomerulonephritis.

184 cases of acute poststreptococcal glomerulonephritis were investigated and six of these were associated with a peculiar, uncommon pneumonia, and another one had a lethal course. The clinicoradiological and especially pathological data summarized in this study attempt to demonstrate the individuality of this type of pneumonia. Pneumonia associated with acute poststreptococcal glomerulonephritis is similar or identical to rheumatic pneumonia.
