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. The single similar case report was published before the era of electron microscopy and immunohistochemistry and single cases of atypical and malignant forms in this unusual location were published only recently. The tumour measuring 5 x 4 x 2 centimeters has caused cough and was associated with occasional righ-sided chest pain. Its rich vascular supply has caused intensive intraoperative bleeding. The postoperative course was uneventful and the patient is free of neoplastic disease or symptoms six years after surgery. Numerous mast cells present within the tumour's interstices must be considered in relation to the possible pathogenesis of the up to now unexplained pain in glomus tumours.

[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. The second patient underwent transplantation of the kidneys precedingly to bilateral subtotal resection of both lobes of the thyroid gland due to marked bilateral nodal goitre intervening deeply retrosternally with a severe pressure syndrome on trachea and oesophagus. The immediate and long-term results were excellent. Orthotopic transplantation of the heart in the third patient preceded to intercostal drainage of the thorax and evacuation of pus due to an extensive empyema of the thorax and septic state, and later thoracotomy and decortication with extirpation of the substantial part of the empyema sack was performed with an excellent immediate and long-term effect. The authors present the principles which must be inevitably fulfilled in coincidence with successive surgical treatment in patients with transplanted organs in a permanent immunocomplex regime.

[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. Atypical mastocytes displayed metachromasia with toluidine blue and positive naphthol-AS-D chloroacetate esterase. Symptomatic treatment with sodium cromoglycate reduced temporarily the frequency of flushing episodes, but it was not possible to arrest the increase of the mastocyte mass by cytostatic treatment.

[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.

Non-invasive methods for detection of cardiomyopathy in the course of antineoplastic treatment.

In our group of patients suffering from cancer and treated by polychemotherapy and monitored in a complex non-invasive way we obtained data as follows: A normal physical, sensoric and biochemical cardiac finding prior to treatment has been observed in 47 patients out of 68 (69.1%). A pathological cardiac finding prior to treatment has been found in 18 patients out of 68 (26.5%). Pathological changes evidencing for cardiomyopathy (CMP) induced by chemotherapy have been detected in 19 patients out of 68 (27.6%). Out of 18 patients with a pathological report prior to treatment in 8 of them the polycardiographic, echocardiographic, and biochemical alterations deteriorated during the chemotherapy. CMP induced by polychemotherapy has been found altogether in 27 patients out of 68 (39.6%). In this group of patients with clinically and biochemically detected CMP due to antineoplastic treatment, we found a significant decrease of ejection fraction (EF) (values less than 50%) and a marked increase Weisler's index (WI) (values greater than 0.520) approximately in 30% of patients. Our preliminary results show that polycardiographic examinations of systolic time interval (STI), the EF detected echocardiographically, as well as determination of myocardial isoenzyme creatine phosphokinase (CK-MB) activity represent useful non-invasive methods of early detection of any myocardial damage in the course of actinochemotherapy. A systematic monitoring of patients reduces the uncertainty with antitumor chemotherapy so that it enables--in a majority of cases--to bring the planned antineoplastic treatment to a successful end.
