Work-related musculoskeletal disorders in Polish sonographers-A questionnaire study.

Purpose: The ultrasound specialists face a substantial issue with work-related musculoskeletal disorders (WMSDs), characterized by occupation-related pain, reaching an estimated frequency of up to 90.5%. The type and location of pain vary depending on the sonographers specialty and the specific anatomical areas being examined.

No association between Helicobacter pylori infection and gastrointestinal complaints in a large cohort of symptomatic children.

Aim: This Polish study estimated the prevalence of the Helicobacter pylori infection in symptomatic children aged 3-18 and investigated its association with gastrointestinal complaints.

Methods: We prospectively enrolled 1984 children (54% female) with a mean age of 9.5 ± 4.

[Analysis of severe and threefold atypical and serious course of catatonic-paranoid psychosis].

The paper describes the difficult course of catatonic-paranoid psychosis which began with symptoms similar to the myasthenia. The growing symptoms of catatonia (in this oral mechanisms with the compulsion of mastication, injuring with teeth of the mouth, tongue biting and damage, such as lockjaw) brought about choking which was followed by aspiration pneumonia. The patient had to have pharmacological coma induced, along with muscle relaxation and artificial ventilation in the conditions of the intensive care department.

Expression of naive/memory (CD45RA/CD45RO) markers by peripheral blood CD4+ and CD8 + T cells in children with asthma.

Introduction: The role of CD4+ T cells in the immunopathogenesis of asthma is well documented. Little is known about the role of CD8+ T cells. The aim of this study was to assess peripheral blood subsets of CD4+ and CD8+ T cells expressing naive/memory markers (CD45RA+/RO+) and the activation marker (CD25+) in children with allergic asthma.

[Autoregulation of cerebral circulation: adaptation to hypertension and re-adaptation in response to antihypertensive treatment].

In chronic hypertension, autoregulation of cerebral blood flow (CBF) is adapted to high blood pressure. Thus in untreated hypertensive patients, the autoregulation curve is shifted towards higher pressure. With antihypertensive treatment autoregulation curve may be shifted back to the normal position or shift upward to the beneficially higher level of CBF.

Methimazole-induced toxic epidermal necrolysis in a 12-year-old girl.

We report a 12-year-old girl with hyperthyreosis who presented methamazole-induced toxic epidermal necrolysis (TEN). The patient's past history suggests a presence of autoimmune disease. To our knowledge it is the first report describing such an adverse effect of methimazole.

[Clinical evaluation of nitrates in exercise-induced angina].

Nitroglycerine (NTG) is still the most important angina relief drug. The aim of the study was to evaluate clinical effects and tolerance of sublingually nitroglycerine sub form Nitromint-spray in patients with exercise induced angina pectoris (AP) using treadmill electrocardiography stress test (EST). The study group consisted of 40 adults patients (mean age 57.

[The comparison of clinical effectiveness of perindopril and acebutolol in the primary hypertension treatment].

Hypertension is one of the most important risk factors for ischaemic heart disease and stroke. The aim of our study was to assess the antihypertensive effect of angiotensine converting enzyme inhibitor (perindopril) versus beta blocker (acebutolol) in hypertensive patients. It was a double blind, placebo controlled study performed in the group of 31 patients (16 males, 15 females; mean age 46.

Comparison of the effect of perindopril and acebutolol on cerebral hemodynamics in hypertensive patients.

Purpose: The aim of the study was to compare effect of perindopril (4 mg once a day) versus acebutolol (400 mg once a day) on cerebral hemodynamics in hypertensive patients.

Methods: Thirty untreated patients with mild-to-moderate hypertension were studied. Drug influences on Doppler-derived parameters from the cerebral blood flow (CBF) velocity wave form were evaluated in a randomized, double blind, cross-over, placebo controlled study.

[Physiological and pathophysiological role of histamine in the gastrointestinal tract].

In this paper, the authors discuss problems concerning the role played by histamine in various physiological and pathological processes in the gastrointestinal tract. The synthesis and metabolism of histamine is described. Apart from participation in many physiological processes, e.

[Evaluation of the antihypertensive efficacy and safety of using sustained release verapamil in elderly subjects using ambulatory blood pressure monitoring].

Objective: Calcium antagonists are commonly used drugs in the treatment of hypertension in elderly patients. One of the drugs of this group is verapamil. Especially its slow release formula is convenient for use in elderly patients (drug is given once daily).

Studies of aqueous humor proteins in rabbits after posterior chamber lens implantation.

In 13 rabbits, 1 month to 1 year after posterior chamber lens implantation/polymethylmetacrylate/, the level of aqueous humor proteins was evaluated and the proteins separation in polyacylamide gel was performed. The studies were also carried out in unoperated eyes of the same animals and control group was composed of the eyes before surgery. It was found that in pseudophakic eyes an increased level of proteins remained during the whole year/the highest one month after surgery, slowly decreasing afterwards/, with the appearance of additional fractions.
