[A case of ossifying fibromyxoid tumor].

Recently described entity: ossifying fibromyxoid tumour of soft parts is presented. Schwann cell nature of the proliferating cells was demonstrated by immunohistochemical means. This special kind of nerve sheath tumors is characterised by pathological differentiation of the cells, resulting bone and in some cases additional cartilage formation. As for biological behaviour: in spite of occasional histological evidences of malignancy, no distant metastases are to be expected. Local aggressivity and recurrences may occur, thus designation is preferable as semimalignant or according to more modern terms as low-grade malignant tumour.

["Snapping wrist" caused by tumor of the flexor tendon].

The snapping wrist, in contrary to the snapping finger, is a rare lesion. The knot caused by tumour, synovitis, rheumatic or partial tendon injury gets at the motion of the tendons in the carpal canal accompanied by a snapping phenomenon. Authors describe one case in which the causative factor was a benign tumour. After its removal the phenomenon and the complaints disappeared.

[Infectious complications of 227 open fractures of the leg].

Out of 557 open fractures of the leg we have analysed 472 cases in respect of recovery. We tried to discrive the relationship between the infection and the severity of the lesion and the methods of treatment resp. We have analysed also the further course of the infect.on. In our material considerable risk of the infections in the case of open leg fractures was found, since the incidence of all infections corresponded--in accordance with the data of the literature--to 16,7% of the appreciable cases. Significant relationship between the occurrence of infections and the severity of the lesion was found. In the material analysed according to the ACD code the incidence of infections is in the severely injured patients three times as much as in the case of slight or moderately severe groups. The occurrence of posttraumatic osteitis corresponds to 9,11%--this latter is similarly in relation with the severity of the lesion. The infection leads to the protraction of the osseous union,--however, no convincing data were found in the authors' material in respect of the relationship between the infection and the methods of treatment. The course and the proportion of healing of the infected cases correspond to the mean values reported in the literature. On the basis of their great material it is stated by the authors that only in the case of lesions with identical or at the least similar severity comparison of the results of recovery or of the complications is possible and suitable.

[Sodium concentration and pre-eclampsia: is salt restriction of value?].

UNLABELLED: The significance of sodium metabolism with respect to preeclampsia is discussed in the literature with a wide range of diverging opinions. The presented work analyses the influence of a low salt diet on the symptoms of preeclampsia and the consequences for the newborn. MATERIAL AND METHODS: 160 patients with preeclampsia between 1989 and 1993 were retrospectively studied. Serum sodium values (at hospital admission, lowest prepartal level, immediate and 3-8 days postpartum) were compared with the corresponding gestosis symptoms. RESULTS: The mean sodium serum concentration at admission was 135.6 mmol/l (lower norm: 136 mmol/l). This was significantly different from the mean lowest prepartal value of 134.9 mmol/l (p < 0.0001). Postpartum the mean fell again significantly to 134.0 mmol/l (p < 0.0001). None of the parameters for gestosis symptoms, which were investigated (diastolic blood pressure, edema, proteinuria, serum protein levels and hyperreflexia) showed any statistically significant association with the serum sodium concentration. Five patients had very low serum natrium values, 130 mmol/l, either at admission or during hospitalisation. Three of the five infants of these patients had hyponatremia; two needed sodium supplementation. CONCLUSION: There seems to be no reason supporting a low salt diet as therapy for preeclampsia, since it does not affect the symptoms and might lead to hyponatremia in the newborn.
