[Aortic regurgitation and aortic stenosis associated with gastrointestinal bleeding. Report of a case (author's transl)].

A 67-year-old woman with a double atherosclerotic aortic valvulopathy and rheumatoid arthritis presented recurrent episodes of gastrointestinal bleeding. Selective arteriography of the superior mesenteric artery demonstrated the existence of vascular malformations with extravasation of the contrast. The physiopathology of this lesion is unknown, but its incidence in adulthood suggests a degenerative process. A selective angiogram of the superior mesenteric artery is mandatory in patients with gastrointestinal bleeding and double aortic valvulopathy in order to establish the etiological diagnosis of the hemorrhage.

Sleep apneic episodes as indications for adenotonsillectomy.

Fourteen children with adenoid and tonsillar hyperplasia were studied for one night in the sleep laboratory. Six of the children had at least 40 apneic episodes per night, mostly central or obstructive. The largest number of episodes was found in rapid eye movement sleep. Mixed episodes were the longest and central episodes the shortest. Adenotonsillectomy was performed on children with at least 40 episodes and on children with predominantly obstructive episodes. In two of these children, preoperative and postoperative recordings were taken, revealing a reduction in the total number of apneic episodes and a complete disappearance of obstructive episodes. These results suggest that polysomnographic recordings can provide useful information regarding the necessity of adenotonsillectomy.

Maintenance oral theophylline therapy: suggested schedule in elderly patients.

18 elderly patients (17 male and 1 female) with chronic obstructive pulmonary disease, and 2 elderly patients (1 male, 1 female) with an acute asthmatic attack were treated with theophylline. Receiving the same intravenous loading dose (5.6 mg/kg) and oral maintenance dosage (1,500 mg), the patients were divided into two groups (A and B) differentiated only by the time interval between oral doses (tau). Group A was treated every 8 h, and group B every 6 h. Although theophylline levels in both groups were similar during the infusion period, patients in group B fared significantly better (p less than 0.01) than patients in group A in reaching a therapeutic blood theophylline level. We conclude that an average dosage of 20 mg/kg of theophylline divided in 6-hour intervals is the more effective schedule in elderly patients without cardiac or hepatic involvement.

Echocardiography in infective endocarditis. Lack of specificity in patients with valvular pathology.

59 patients with suspected infective endocarditis on a natural valve were studied by M-Mode echocardiography to determine the specificity of the ultrasonic technique in detecting valvular vegetations. All echocardiograms were read independently by two observers who were unaware of the final diagnosis. Among 40 patients who later proved not to have infective endocarditis, two (5%) were diagnosed by echocardiography as having either possible or probably vegetation by at least one observer. Both patients with a false positive diagnosis of vegetation had pre-existing valvular pathology, the presence of which greatly complicated the interpretation of the echocardiogram. Inter-observer disagreement occurred in 5 of the 59 studies (8.5%). The results of this study suggest that caution should be exerted in the echocardiographic diagnosis of vegetation in patients with pre-existing valvular pathology.

Systemic lupus erythematosus, Sjögren's syndrome and glomerular nephritis.

The combination of systemic lupus erythematosus, Sjögren's disease and severe diffuse glomerular nephritis has only rarely been reported. A 14-year-old girl is described with lupus nephritis in whom co-existent clinical and histological features of Sjögren's syndrome were found. These include bilateral parotid enlargement, xerostomia, increased serum amylase, reduced salivary secretion and lymphocyte infiltration of both salivary glands and kidneys. The co-existence of systemic lupus erythematosus with Sjögren's syndrome is discussed together with a consideration of pathogenesis.

The Pickwickian syndrome with hypertrophy of tonsils: a re-appraisal.

Pronounced tonsilar hypertrophy was found in two obese patients suffering from hypersomnolence, periodic attacks of apnea and disturbing snoring at night. Both patients underwent tonsillectomy. Immediately after the operation the hypersomnolence disappeared, the breathing became normal, and the disturbing snoring at night ceased. Follow-up over a period of three years did not reveal any recurrence of these symptoms, even though the patients had not lost any weight during this period.
