Correlation between parents and child's version of the child health survey for asthma questionnaire.

Background: The American Academy of Pediatrics Children's Health Survey for Asthma (CHSA) is a widely used instrument to assess various aspects of health and well-being in relation to asthma. There is a parent and a child version of this questionnaire and little is known about the concordance between these versions.

Method: In a cross-sectional study conducted in 13 facilities, hospitals and outpatient clinics covering all areas of Kosovo, children with asthma aged 7-16 years were enrolled.

Experimental study of sutureless vascular anastomosis with use of glued prosthesis in rabbits.

Objective: The objective of this study is to explore the feasibility and efficacy of a new technique for sutureless vascular anastomosis, using glued prosthesis, as a sole anastomosis fixation method in rabbits.

Methods: Ten rabbits were randomly selected to conduct the experiment. Five rabbits underwent direct anastomosis of infrarenal abdominal aorta, with glued prosthesis.

Expression of immunohistochemical markers of progression in pre-cancerous and cancerous human colon: correlation with serum vitamin D levels.

Background/aim: We aimed to evaluate vitamin D levels in blood, as well as the immunohistological expression of β-catenin, p21 activated kinase (PAK1), p53 and Ki67 in relation to histological type and grading of colonic tumors. RESULTS were compared to the expression in normal and adenomatous colon.

Materials And Methods: We analyzed colorectal specimens from 20 patients with colorectal tumors for expression of β-catenin, PAK1, p53 and Ki67.

Phentolamine action in permeability of airways at patients with bronchial asthma.

In this work, effect of phentolamine as antagonist of alpha-1 adrenergic receptor in patients with bronchial asthma and with obstructive chronic bronchitis was studied. Parameters of the lung function are determined by body plethysmography. Raw and ITGV were registered and SRaw was calculated as well.

Action of propranolol in the reaction of smooth musculature of tracheal rings induced with acetylcholine, histamine, serotonin (5-HT) and prostaglandin (PGF2-alfa) in vitro and in vivo.

Actions of acetylcholine (ACh), histamines, serotonins (5-HT) and prostaglandins (PGF2-alfa) in concentrations of 10(-4), 10(-3), 10(-2) and 10(-1) mol/dm(3) were analyzed in vitro conditions in isolated specimens of tracheas of 24 pigs, 7 guinea pigs, and dead persons for different reasons (8), in the presence and without presence of propranolol. Whilst, research regarding actions of aerosolized histamines (10 mg, 1%, 2 min), in the presence and without the presence of aerosolized propranolol (20 mg, 2%, 2 min) was done in vivo in 6 healthy persons. Study results show that propranolol does not emphasize contraction of the airways smooth musculature as induced by ACh, histamine, 5-HT and PGF2-alfa in vitro conditions (p>0,1).

Prognostic values of thyroid tumours.

Thyroid cancer accounts for approximately 1% of total cancer cases in developed countries. The aim of this study has been to analyze the histopathological variants of thyroid tumours with regard to gender and age. Despite their relative rarity in our material, they exhibit a wide range of morphological patterns and biological behaviour.

Colorectal cancer: prognostic values.

After lung cancer colorectal cancer (Cc) is ranked the second, as a cause of cancer-related death. The purpose of this study was to analyze the Cc cases in our material with respect to all prognostic values including histological type and grade, vascular invasion, perineural invasion, and tumor border features. There were investigated 149 cases of resection specimen with colorectal cancer, which were fixed in buffered neutral formalin and embedded in paraffin.
