[Total laparoscopic hysterectomy with the coagulation of the uterine arteries at their origin].

Introduction: Hysterectomy is one of the most frequently performed gynecological operations worldwide. Due to patient perceived advantages of technical development laparoscopic hysterectomy has become a widely used method. The attitude of patients, surgeons and service providers to laparoscopic procedures is not uniform, but total laparoscopic hysterectomy has prevailed due to its advantages from other types of laparoscopic hysterectomies.

Characterization of human pituitary adenomas in cell cultures by light and electron microscopic morphology and immunolabeling.

The morphology and hormone production of pituitary adenoma cell cultures were compared in order to highlight their characteristic in vitro features. Cell suspensions were prepared from 494 surgical specimens. The 319 viable monolayer cultures were analyzed in detail by light microscopy and immunocytochemistry within two weeks of cultivation.

Effect of a single high-dose gamma irradiation on cultured cells in human cerebral arteriovenous malformation.

Object: The purpose of this study was to analyze the effect of single high-dose gamma irradiation at a cellular biological level on tissue cultures obtained in patients who underwent surgery for cerebral arteriovenous malformation (AVM).

Methods: The cell proliferation indices and changes in activation of p53, p21Waf-1, and mdm-2 were determined. Additionally, immunohistochemical investigations for vimentin, desmin, alpha-smooth muscle actin (alpha-SMA), glial fibrillary acidic protein, Factor VIII-related antigen (F-VIII), cytokeratin, S100, and transforming growth factor-beta (TGFbeta) were performed on cultured AVM cells after a single high-dose irradiation.

Identification of gliomas by morphological and immunocytochemical analysis in cell cultures.

Introduction: The morphology and immunocytochemical properties of 250 different monolayer cultures derived from various human brain tumor specimens were investigated on purpose to support and complement the neuropathological diagnosis. In this study analyses of 124 glioma cases are presented.

Methods: The tumor samples were mechanically dissociated and seeded on glass coverslips.

[A case of central nervous system atypical teratoid / rhabdoid tumor].

The atypical teratoid / rhabdoid tumour is a rare type of tumours of central nervous system appearing usually under 2 years of age, bearing a rather bad prognosis and it may cause serious differential diagnostic problem. The tumour is characterized histologically by the presence of the rhabdoid cells, immunohistochemically by vimentin, SMA, EMA positivity, the frequent presence of cytokeratin, GFAP positivity, but germ cell markers: AFP, hCG negativity, cytogenetically by aberrations of chromosome 22. The case of a one and half month old female infant is presented, who died 8 months after the appearance of the first symptoms.
