[Right atrial thrombosis: clinical and pathological findings and course (author's transl)].

Possible correlations between clinical and pathological findings and the results of various paraclinical tests were studied in 17 patients with right atrial thrombosis. Positive correlations existed with supraventricular rhythm disorders, particularly sinus node lesions. The presence of massive pulmonary emboli in all cases is suggestive of the origin of the thrombus being within the atrial cavity. Presumptive signs of right atrial thrombosis are the sudden unexplainable worsening of cardiac insufficiency factors, the appearance of paroxystic disturbances in supraventricular rhythm, and associated signs of pulmonary embolism due to peripheral venous disorders.

[Chronic dacryocystitis fistulization in a Rubinstein-Taybi syndrome].

The article presents the treatment difficulties of the chronic dacryocystitis at an eight month old patient, diagnosed with Rubinstein-Taybi syndrome. The difficulties occurred as a result of numerous antibiotic treatments and surgical procedures suffered by the patient since his second week of life.

[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. Stress is laid on the presence of atrophy of the villi in children with hepatic steatosis, proof of a lesional substrate of malabsorption in this disease. The authors note the early onset of hepatic lesions, the gravity of the cases with an early clinical expression and hepatic biopsy puncture as the only method revealing hepatic affection in cystic fibrosis. In the first semester of life there exists purely digestive forms, hepatic steatosis and oedematous dystrophy in infants at this age being highly suspect of the etiology.

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. In both entities, pneumonia and pulmonary edema may and do coexist, and the differentiation of pneumonia from congestive heart failure is difficult and often impossible without pathological evidence. The most attractive pathogenic interpretation is the hypothesis of an immune mechanism in the induction of pneumonia. Authors attributed the lung changes, consecutive to a vascular damage, to a hypersensitivity phenomenon, with accumulation of fibrinogen in alveoli where it is converted to fibrin. Then, the hyaline membrane lining the alveoli, an important feature of pneumonia associated with glomerulonephritis is built up. It is, however, plausible that the effect of the immune reaction is associated with those of hydrosaline retention, arterial hypertension and congestive heart failure. Analogous to rheumatic pneumonia, the "peculiar pneumonia" associated with acute poststreptococcal glomerulonephritis should be named nephritic pneumonia.
