Evaluation of the accuracy of the postural stability measurement with the Y-Balance Test based on the levels of the biomechanical parameters.

Purpose: The study of dynamic balance involves tests that assess the muscle control of spatial changes of the position of the centre of gravity over the base of support. The purpose of this work was to determine the structure of the Y-balance test and its accuracy based on the measurements of strength performance of the muscles acting on the knee joint as well as the flexibility and balance in boys aged 14 years.

Methods: The study included 43 schoolboys regularly participating in physical education lessons.

Analysis of spirometry results in hospitalized patients aged over 65 years.

Introduction And Objective: The growing population of the elderly, as well as the occurrence of coexisting diseases and polypharmacy, is the reason why diseases of patients aged $65 years belong to the major issues of the contemporary medicine. Among the most frequent diseases of the elderly, there are respiratory system diseases. They are difficult to diagnose because of the patient group specificity, which is the reason for increased mortality among seniors, caused by underdiagnosis.

Antimicrobial susceptibility of Helicobacter pylori isolates from Lower Silesia, Poland.

Introduction: In recent years the failure of standard therapy for Helicobacter pylori infections has been observed, which results primarily from the increasing resistance of H. pylori strains to antibiotics. The aim of the study was to estimate the prevalence of antimicrobial resistance of H.

[Esophageal substitute corrective operations].

In the Clinic of Gastrointestinal Surgery at the Medical University in Wrocław in 402 cases substernal oesophageal reconstruction was performed using different pedunculated oesophageal substitutes. 63 patients had to be operated on for the second time because of disorders in the oesophageal substitute. In 13 cases stenosis in the upper anastomosis and in 3 patients stenosis in the anastomosis with stomach were corrected.

[The second reconstructive operation of the esophagus].

What we need in order to obtain good results in oesophageal reconstructive surgery is long enough segment of intestine with sufficient blood supply. Evaluation of the blood flow is very difficult and often only after completion of the mobilization and transposition of the intestine into the neck final evaluation can be made. In the cases with poor blood flow one must resign from the already mobilized intestine.
