[Combined Symptomatic Treatment of Groin Pain Syndrome in Professional Football Players - Prospective Study Results].

PURPOSE OF THE STUDY The results of the prospective study evaluating the outcomes of a combined therapeutic approach of non-operative therapy of Groin Pain Syndrome (GPS) in professional football players are presented. MATERIAL AND METHODS The evaluated cohort consisted of a total of 31 football players of a professional football club divided into two groups. The Group 1 included 10 symptomatic patients suffering from GPS for at least 4 weeks, the Control Group 2 included 21 healthy football players not suffering from GPS.

[Primary bone hyperparathyroidism].

The authors report the case of a 19-year-old girl with osteolytic bone lesions in whom primary hyperparathyreoidism caused by parathyroid gland adenoma was diagnosed. They emphasize necessity to be aware of a relationship of this rare condition to bone lesions that may be benign in appearance and may show ambiguous histological findings. The patient underwent excision of the adenoma and subsequent substitution therapy, which resulted in the healing of bone lesions.

Susceptibility of individual cells of Saccharomyces cerevisiae to the killer toxin K1.

The susceptibility of sensitive yeast to killer toxins is known to depend on various factors, such as the selected killer toxin, the exposed yeast strain, its growth phase and the state of culture under given experimental conditions. The aim of this paper was to find whether individual cells from one culture are equally susceptible to the impact of the killer toxin. For this purpose the rhodamine B assay in a modified form was used.

Effects of fluorescent pseudo-ATP and ATP-metal analogs on secondary structure of Na(+)/K(+)-ATPase.

The secondary structure of Na(+)/K(+)-ATPase after modification of the ATP-binding sites was analyzed. Consistently with recent reports, we found in trypsin-treated Na(+)/K(+)-ATPase additionally to alpha-helix also beta-sheet structures in the transmembrane segments. However, binding of fluorescein 5'-isothiocyanate (FITC), the pseudo-ATP analog, to the ATP-binding site did not affect the secondary structure of undigested Na(+)/K(+)-ATPase.

[Leiomyosarcoma of the bone.].

The case history presents a patient with a rare malignant bone tumor - leiomyosarcoma in the region of distal femur. A large resection of the tumor was made with a specially tailored distal femur replacement. The authors emphasize the necessity of a detailed histological examination including immuno-histochemistry which proved the diagnosis of leiomyosarcoma as opposed to the original diagnosis of fibrosarcoma.
