Benign glomus tumor of the superior posterior mediastinum.

An unusual location of a benign glomus tumour, outside of the constantly located regions, e.g. in the subungual location or deeply sited in extremities, was diagnosed in a 56-year-old white female in her posterior upper mediastinum.

[Surgery in patients with organ transplants].

Patients after successful transplantation with immunosuppressive therapy form a "new circle of surgical patients" who can develop various surgical diseases, or injuries which bring about an inevitable urgent or planned surgical treatment. The authors present the results in three patients with transplanted organs (1993-1995) who were subdued to various surgical treatments. The first patient underwent a classical cholecystectomy, choledochotomy, and extraction of concrement from the choledochus after orthotopic transplantation of the heart.

[A case of systemic mastocytosis].

The authors describe a rare case of systemic mastocytosis without skin infiltration. The first symptom were episodes of flushing in the face and upper trunk. From the case-history it was assumed that the condition had a several year's benign course, the diagnosis was established in the stage of malignant acceleration of the disease from bone marrow biopsy and liver biopsy.

[Creatine kinase and lactate dehydrogenase in the early diagnosis of acute myocardial infarct].

The authors investigated in a group of 504 patients--357 men and 147 women with acute myocardial infarction on admission to hospital--the relationship between the ECG finding and values of catalytic concentrations of isoenzymes CK-MB and LD-1 LD-2. They found that isoenzymes CK-MB and LD-1 LD-2 are a more sensitive indicator of acute IM than the ECG tracing. Not even a negative ECG tracing when the total catalytic concentrations of CK and LD are not elevated rules out the possibility of acute myocardial infarction.
