[Effect of physical training on children after reconstructive heart surgery].

The authors composed a programme of physical training for children with congenital valvular defect. The training programme was applied before and after the heart operation. Two years after a successful reconstructive heart operation the fitness condition of 40 children was examined. The average age of the children was 8.0 +/- 3.6 years. Twenty of the children participated and 20 did not participate in the programme. The physical condition of the children who took part in the training was found to be significantly better than that of the others without training.

[Prognostic factors affecting survival in multiple myeloma].

70 patients suffering from multiple myeloma were observed by authors in the last 15 years and three months. In the meantime fifty-two out of them have died, and 18 patients are under permanent care. 43 IgG, 17 IgA, 6 Bence-Jones, 2 IgD types were diagnosed according to the paraprotein distribution, one patient proved to be nonsecretory, and an other one to osteosclerotic form as well. The median survival time was 27 months in the group of deceased patients. In the group followed-up 50.8 months survival time was observed up to the closing of the study. Several prognostic factors were investigated. According to the classification by Durie and Salmon the survival time was 60 months in the patients with stage I, 33 months in stage II., and 9 months in stage III respectively. The prognosis is much poorer in patients into the "B" category: the survival time was 14 months. Classified in the basis of the type of the myeloma-cell, the cases with well matured cells have had the best prognosis with survival time of 46 months, while the most unfavourable prognosis was observed in patients with blast-cell type, with a median survival time of 10 months. The greatest number of patients suffered from multiple myeloma of IgG paraprotein type, in this group the serum IgA level was found to be significantly decreased in the patients died due to inevitable infections. The survival was injured significantly by the occurrence of concomitant severe diseases, to.(ABSTRACT TRUNCATED AT 250 WORDS)

[Cryptosporidium as a co-pathogen in infantile diarrhea and pneumonia].

The authors describe a case of cryptosporidiosis in a 10 month old immunocompetent infant, who suffered from prolonged diarrhoea and pneumonia. Cryptosporidium oocysts, Giardia lamblia were detected by using modified Kinyoun stain, and klebsiella was identified in the stool culture. According to the clinical presentation and the laboratory data the streptococcus infection is presumed as cause of the pneumonia, but the authors could not exclude the role of cryptosporidium in predisposing and/or causing the pneumonia.

Multielectrode culture chamber: a device for long-term recording of bioelectric activities in vitro.

A multi-microelectrode culture chamber system was constructed for monitoring simultaneously morphological and electrophysiological development of neural cells in vitro. The setup consisted of a pattern of gold conductor lines evaporated onto a glass substrate and insulated with polyamide. The width of each electrode was 10 microns, and the distance between the electrodes was 60 microns. The electrode patterns were constructed and the uncovering of the electrode tips were carried out by photo-etching. This system allowed us to record spontaneous activities in both explant- and primary monolayer cultures of either rat or mouse spinal cords and forebrains, during neuronal regeneration and maturation.

[Discoid lupus erythematosus beginning on the eyelids].

We report on a 20-year-old women, who suffered from discoid lupus erythematosus (DLE) beginning on her eyelids with dyschromia and cutaneous infiltration. Similar signs appeared on the top of her nose, her nostrils, and her lower lip. Simultaneously with these alterations, we found a superficial exulceration on her hard palate, which histologically proved typical for DLE. After therapy with chloroquine for 3 weeks, the alterations disappeared.

[Prognostic role of immunoglobulin levels in chronic B cell lymphoid leukemia].

The authors analyse the prognostic role of the immunoglobulins detected in the sera of 83 patients with B-cell chronic lymphocytic leukaemia. They have found, that the decreased level of IgG, IgA and IgM itself has no significant prognostic role. In those cases, where the IgA level was the lowest at the recognition of the disease, the expected life-span was significantly shorter. As far as the immunoglobulin level and the clinical stage did not show any significant correspondence, the relative reduction of the IgA level at the recognition of the disease can be considered as a poor prognostic sign.

[Significance of seemingly intact urothelium in patients with bladder cancer].

During 9 years (from 1979 to 1988) the authors performed 412 multiple cold biopsies taken from 9 different points of the cancerous bladder in 263 patients. In 42 per cent of the patients the hystopathological examination of biopsy materials discovered dysplasia, carcinoma in situ or tumor of the grossly normal urothelium. The frequency of these proliferative lesions is closely connected with number, configuration, grading and depth of infiltration of overt bladder tumor. These lesions indicate the probable recurrence-rate as well as danger of the more progressive recurrence.

Congenital factor XIII deficiency with multiple benign breast tumours and successful pregnancy with substitutive therapy. A case report.

A 34-year-old woman with congenital factor XIII (FXIII) deficiency and multiple connective tissue tumours is reported. The subunit a of FXIII was totally absent in her plasma, platelets and histiocytes of breast fibroadenomas and considerably reduced in the monocytes (below 5%). The plasmatic level of subunit b was also reduced (25%). She had a bleeding tendency and habitual abortions. Fresh frozen plasma therapy permitted a successful pregnancy.

45,X streak gonad syndrome associated with bilateral 'burnt out' gonadoblastoma.

A 28-year-old woman with well-developed female secondary sexual characteristics, secondary amenorrhea, short stature and a few somatic anomalies of streak gonad syndrome who had bilateral 'burnt out' gonadoblastoma associated with 45,X karyotype is reported. Although the exact source of steroid production in the present case could not be defined, it seems probable that the tumor once secreted steroid hormones which were responsible for the development of the female secondary sexual characteristics. At the time of diagnosis there was no evidence of hormonal activity of the tumor. Cases of gonadoblastoma without Y chromosome are reviewed. The diagnostic difficulties encountered in patients with gonadoblastoma not associated with Y chromosome are discussed.

Multiple primary malignant tumours of patients treated for colorectal carcinoma (clinical analysis of 61 cases).

Multiple primary malignant tumours were found by the authors in a population of 543 patients treated during 10 years for colorectal cancer at an incidence rate of 11.2%. Thirty-nine of 69 patients had tumours of metachronous and 22 of synchronous appearance. Of patients treated for multiple tumours, the ratio of women (p less than 0.1) was much higher, the average age was much (2 years) higher and occurrence of malignant disease in the family was more frequent than in those with a solitary tumour. Based on the high incidence reported on in the literature and in their own material, they draw attention to the practical, clinical aspects of the problem. The difficulties in diagnosing multiple colonic tumours are described in detail, pointing out the importance and possibility of pre- and intra-operative examinations aiming at completeness. Based on survival data, it is stated that multiple malignancies do not by all means imply incurability. An improvement of therapeutic results is expected, beside the improvement of surgical results, of the introduction of up-to-date examination methods, of the care and continuous follow-up of the patients at risk.

[Lymphangitis carcinomatosa].

The authors present a 86 years old male patient with gradually developing upper right arm swelling. There were several hyperaemic papules, vesicles and teleangiectases on his arm. The histology revealed a lymphangitis carcinomatosa. There were no signs of any tumor, but multiple isotope accumulations in the bones. Anaplastic thyroid gland carcinoma with multiple metastases were found at autopsy.

[Partial mole with lung metastases and multiple abnormalities of the fetus].

The authors report on a patient with partial mole, multiple malformations and lung metastases requiring chemotherapy. This case shows that the partial hydatidiform mole must therefore be carefully monitored by serial beta-hCG titres following evacuation to ensure the achievement of complete sustained remission.
