BACKGROUND Hyperosmolar solutions have been used in neurosurgery to modify brain bulk and prevent neurological deterioration. The purpose of the study was to compare the effects of equivolume, equiosmolar solutions of mannitol and hypertonic saline (HTS) on brain relaxation and postoperative complications in patients undergoing elective intracranial tumor(More)
BACKGROUND Radical surgery of renal cell carcinoma spinal metastases carries a high risk due to potentially life-threatening extreme blood loss. Radical preoperative embolization of renal cell carcinoma metastases alone is not necessarily a guarantee of extreme blood loss not occurring during operation. METHODS A retrospective analysis of 15 patients(More)
By means of radioimmunoassay, the content of endogenous cortisol in the aqueous humour and plasma of 35 patients suffering from various types of glaucomas and 35 cataract patients was determined, and the ratio of the plasma to the aqueous humour cortisol levels was calculated. The highest cortisol level in both plasma and aqueous humour was found to occur(More)
OBJECTIVE Determination of various biomarkers, such as beta-amyloid, tau-protein, phosphorylated tau-protein in CSF and their sensitivity and specificity in neurodegenerative brain processes, in particular Alzheimer Dementia (AD), has been recently investigated to monitor their abnormalities in the CSF at early stages of diseases before the clinical(More)
BACKGROUND The aim of the study is to present results of a prospective uncontrolled clinical study. Percutaneous vertebroplasty or kyphoplasty are minimally invasive methods based on polymethylmethacrylate (PMMA) bone cement application into the damaged vertebra. This leads to decrease of the pain and vertebral body stabilisation. Oncology disorders of the(More)
High grade gliomas are some of the deadliest human tumours. Conventional treatments such as surgery, radiotherapy and chemotherapy have only a limited effect. Nowadays, resection is the common treatment of choice and although new approaches, such as perioperative magnetic resonance imaging or fluorescent microscopy have been developed, the survival rate of(More)
Intensity-modulated radiation therapy (IMRT) is an advanced form of the three-dimensional conformal radiation therapy (3D-CRT). Highly conformal dose distribution is the basic feature of IMRT. The head and neck region is suitable for this new technology since the primary tumor is often surrounded by several critical structures. IMRT offers the ability of(More)
The authors refer to the experiences with the treatment of glaucoma with isoglaucon of 6 months' duration. The intraocular pressure and the frequency of droppings during the entire period of examination were statistically significantly lower (p less than 0.01) in comparison to the starting values. Neither the visus nor the range of the visual field changed.(More)
