[Epidemiological research on primary hyperparathyroidism. A prospective multicenter study].

Serum calcium determination of 11,588 hospitalized patients during a twelve-month period revealed hypercalcaemia in 74 (0.64%). Further clinical and biochemical investigation established primary hyperparathyroidism in 20 of them (27%), and in 15 (20%) a malignant tumour (with bone metastases in six) as the cause of the hypercalcaemia. Rarer causes were found in 11 patients (15%): diuretic medication (5), lithium treatment (3), immobilization (2) or hyperthyroidism (1). In the remaining 28 patients (38%) no cause of the hypercalcaemia could be established with certainty. In at least six patients, however, there were clinical pointers towards hyperparathyroidism in the absence of unequivocal biochemical findings. Leaving out of account borderline cases, one must reckon on a prevalence of hyperparathyroidism in 0.17% of an unselected group of hospitalized patients. Parathyroid hyperfunction must always be considered in the differential diagnosis because of its manifold clinical presentation.

[Exploration of pancreaticojejunal anastomosis by postoperative endoscopic pancreaticography (author's transl)].

Endoscopic pancreaticography (EP) was performed in 9 patients after pancreaticojejunal anastomosis had been established surgically; in 2 of these patients EP was not successful. The anastomosis could be demonstrated in 5 cases to be functioning 1-6 years after operation; in 3 cases the duct system was found to be dilatated, in 2 cases diameters were normal. EP and clinical symptoms correlated well in 4 of 5 cases.

[Endoscopy and radiological investigations of the stomach and duodenum. Alternative or complementary procedures? (author's transl)].

The results of radiological and endoscopic examination in 1,030 patients were compared. In one third of cases there was some discrepancy relating to a significant diagnostic finding (malignant process, peptic ulcer, polyp, stenosis or deformity, abnormal folds, diverticula or normal findings). In analysing false negative and false positive radiological diagnoses, the patients were divided into two groups (with or without a double contrast technique). Conventional radiography proved ten to 38% less reliable than the double contrast technique for a variety of reasons. In view of the high diagnostic accuracy of modern radiological investigations of the stomach and duodenum, endoscopy and biopsy are recommended as complementary procedures. In addition to the high degree of accuracy of radiological methods for various pathological processes, endoscopy places considerable demands during investigation of the upper intestinal tract. At present radiology is used 19 times as frequently as endoscopy, suggesting that there might have to be a tenfold increase in the capacity of pathological departments if endoscopy is used more frequently.

[Retroperitoneal lymphangiodysplasia with exudative enteropathy. A case of cystic dilated cisterna chyli and splenic cysts].

In a 16 years old girl we found the syndrome of exsudative enteropathy with intestinal lymphangiectasy which differs from previous reported cases by several malformations of the lymphatic system. Besides changes in the intestinal lymphatics there was a retroperitoneal lymphangiodysplasia, a reduction and hypoplasia of the lymph vessels in the legs and cysts in the spleen. By substitution of albumin followed by a diet with middle chained triglycerids (MCT), serum protein was stablised but a relapse could not be prevented. Surgical treatment was not possible because the changes were too extensive. The value of diagnostic measures for differential diagnosis of the intestinal lymphangiectasy is presented.
