[Pacemaker's twiddler syndrome (author's transl)].

This report demonstrates the results of five observation of the Pacemaker's-twiddler-syndrome, which will not necessarily end in the complete malfunction of the pacemaker unit. Therefore we classify the Pacemaker's-twiddler-syndrome as a partial and a complete form. The partial form is characterized by still effective cardiac stimulation, whereas the complete form can not stimulate the heart muscle because of the retracted electrode. Also methods of early detection and prevention of the Pacemaker's-twiddler-syndrome are discussed.

[Barrett's syndrome (author's transl)].

Barrett's syndrome is a rare serious ulcerative inflammation of the middle or distal parts of esophagus, characterized by heterotopic gastric mucosa within the esophagus. In 4 cases, diagnosis of Barrett's syndrome suspected by means of x-ray examination was confirmed endoscopically and by taking biopsies under vision. The etiology of the disease is not clear. Alcoholism is common. In our patients, conservative treatment has been used without a great deal of benefit. Only by resection of the parts of esophagus lined by columnar epithelium a beneficial result can be expected, this surgical procedure certainly being a high risk.

[Atypical paraproteinemic hemoblastoses (author's transl)].

The symptomatology of typical paraproteinemic hemoblastoses (plasma cell myeloma, Wadenström's macroglobulinemia) are well known. Once suspected, diagnosis of these disorders can easily be established in the majority of cases. Differentiation of benign paraproteinemias requiring no treatment is likewise possible by careful observation of the course of disease and relevant clinical criteria. Very seldom, cases of paraproteinemic hemoblastoses are seen which differ from the usual immunoelectrophoretic analysis and clinical picture. Two very unusual cases of paraproteinemia are presented.

[Emergency endoscopy: its application in the department of medicine of a city hospital (author's transl)].

In about 90% of cases of active gastrointestinal hemorrage, sources and nature of bleeding can be identified exactly by means of emergency endoscopy. With time passing from the beginning of hemorrhage, diagnosis established by endoscopy is getting less precise. The most common cases of bleeding are peptic lesions, either esophageal, gastric, or duodenal; the most common site of hemorrhage is the stomach. Different potential points bleeding at the same time have to be take in account. A case report of Mallory-Weiss syndrome (13 episodes of hemorrhage) illustrated the method's value in establishing diagnosis of acute gastrointestinal bleeding. Special applications of emergency endoscopy in mental patients are described.

Endoscopic retrograde cholangiopancreaticography (ERCP) in obstructive jaundice caused by metstatic testicular teratoma.

A 28-years-old patient with a palpable mass of two fist's size in the upper abdomen rapidly developed an obstructive jaundice. A pancreatic tumor was suspected and therefore ERCP was carried out. Unusual alterations caused by metastatic lesions of a post mortem diagnosed testicular teratoma narrowing and invading the common bile duct and displacing the main pancreatic duct were visualized.

[Duodenal neurofibroma close to the papilla with hemorrhage and narrowing of the duct of Wirsung and the choledochus (author's transl)].

A solitary duodenal neurofibroma located very closely to the papilla and causing intestinal bleeding could be demonstrated by endoscopy and sonography in a 53 year old female. ERP showed narrowing of the proximal segment of the pancreatic main duct. The diagnosis was confirmed at surgery, in addition it was found, that the choledochus was incarcerated by the tumor as well. A duodeno-hemipancreatectomy after Whipple was performed, because of the localization of the tumor.

[Polyneuropathy in Waldenström's disease].

The clinical course and biopsy and autopsy findings in a patient with asymmetrical polyneuropathy in Waldenström's disease are reported. Under steroid therapy the patient developed mild diabetes mellitus. In the light of the course of the disease, a causal relationship between the hematologic disease and the peripheral neuropathy is assumed. Although a peripheral nerve could not be examined on autopsy, strong lymphocytic infiltration in the autonomic nerves seems to point to a similar pathogenetic mechanism in the development of polyneuropathy. The other possible causal factors are discussed with reference to the small number of reports in the literature.
