Usefulness of conventional and low-dose hydro-CT in the diagnosis of gastric tumors in comparison to endoscopy.

Purpose: The aim of this retrospective study was to evaluate the usefulness of hydro-CT in the diagnosis of gastric tumors in comparison to endoscopy.

Material And Methods: The study involved 40 patients with a diagnosis of gastric tumor established by histopathology who underwent endoscopy and conventional or low-dose hydro-CT. Hydro-CT images were retrospectively analyzed based on the consensus of two radiologists who were blinded to the endoscopy findings.

Evaluation of temporal bone computed tomography and paranasal sinuses magnetic resonance images in acromegalic patients.

Objective: Acromegaly is a rare disease, which symptoms are caused by excess secretion of a growth hormone (GH) from the anterior pituitary benign tumor - adenoma. Authors present an evaluation of computed tomography (CT) and magnetic resonance (MR) images of temporal bone and paranasal sinuses of patients with acromegaly.

Conclusions: 1.

MRI image characteristics of materials implanted at sellar region after transsphenoidal resection of pituitary tumours.

Background: Post-surgical evaluation of the pituitary gland in MRI is difficult because of a change in anatomical conditions. It depends also on numerous other factors, including: size and expansion of the tumour before surgery, type of surgical access, quality and volume of implanted materials and time of its resorption. The purpose was to demonstrate the characteristics of the implanted materials on MRI performed after transsphenoidal resection of pituitary tumours and to identify imaging criteria helpful in differential diagnosis of masses within the sellar region.

[Vestibulo-cochlear disturbances in the course of vaso-neural conflict of vestibule-cochlear nerve--diagnostic and therapeutic problems].

Introduction: Symptoms encompassing sensorineural hearing loss, tinnitus and vertigo occur in many diseases of various origin. The diagnostics in such cases is especially difficult and often requires interdisciplinary cooperation. Despite of that many cases remain unexplained.

Middle-ear ceruminous adenoma as a rare cause of hearing loss and vertigo: case reports.

Middle-ear ceruminous adenomas are rare benign neoplasms arising from the epithelium of the middle ear. Progressive hearing loss, ear fullness and tinnitus are common symptoms of this tumour; facial nerve paresis and vestibular disturbances occur very infrequently. We present two cases of middle-ear ceruminous adenomas, one showed rapid unilateral hearing loss with aural fullness, followed by purulent aural discharge and vertigo.

[Usefulness of imaging in the diagnosis of salivary gland diseases].

Unlabelled: The aim of this study was to evaluate the value of modern imaging modalities in the diagnosis and management of different salivary gland diseases.

Material And Methods: Material comprised of 135 patients (79 women and 56 men) at the age 14-70 (mean aged 35, 7). Ultrasonography (US) was basic examination in every case.

Femoral and iliac vein stenoses after prolonged femoral vein catheter insertion.

Background/aims: Catheterization of the femoral vein is a safe and recommended method of temporary access for haemodialysis. In some patients, however, because of the lack of other possibilities, it is necessary to maintain long-term femoral cannulation. The aim of the study was to evaluate the frequency of stenosis after prolonged femoral cannulation.

Peripheral blood lymphocytes and selected serum interleukins in workers operating X-ray equipment.

The objective of these studies was to determine the effect of low X-ray doses on peripheral blood lymphocytes in the workers operating X-ray equipment. In 30 workers and 18 persons who constituted the control group the absolute number of peripheral blood lymphocytes, the number of T CD4+ and T CD8+ lymphocytes, the ratio CD4+/CD8+ and the concentration of serum interleukins (IL-2, IL-4, IL-6) were tested. Subgroups with respect to sex and employment period were selected.
