Imaging of Complications After Limb Prostheses Implantation in Children with Bone Tumors.

Background: Tumors of the developmental age are an important problem in clinical practice. Primary bone tumors constitute 1-1.5% of all tumors, and 7% of all tumors diagnosed in the developmental age.

Circle of Willis abnormalities in children with neurofibromatosis type 1.

Background And Purpose: The aim of the study was to assess anatomical variants and abnormalities in cerebral arteries on magnetic resonance angiography in 67 children with neurofibromatosis type 1 (NF1).

Materials And Methods: The study included 67 children aged 9 months to 18 years (mean 6.6 years).

[Sonography of small bowel, colon and appendix in children with cystic fibrosis].

Aim: To assess the utility of sonographic examination in estimation of the incidence and character of pathological changes in different parts of the intestine and other abdominal organs in children with cystic fibrosis (CF).

Material And Method: The study group consisted of 182 children (94 girls, 88 boys), aged from 2 months up to 22 yrs, with diagnosed cystic fibrosis or its suspicion, confirmed later. The control group consisted of 20 children with mean age 8 yrs.

Neurocognitive abilities in children with adenotonsillar hypertrophy.

Objective: Sleep apnea is one of the most deleterious disorders in children with adenotonsillar hypertrophy because it can induce hypoxemia of brain. Sleep apnea may lead to failure to thrive or to physical and mental delay in development, including cognitive disturbances. The aim of this study was to analyze the influence of adenotonsillar hypertrophy, causing obstructive sleep apnea on neurocognitive abnormalities.

Autologous hematopoietic stem cell transplantation in patients with refractory Crohn's disease.

Background & Aims: Crohn's disease (CD) is an immunologically mediated inflammatory disease of the gastrointestinal tract. Due to a high morbidity and/or an increase in mortality in refractory cases, a new treatment approach is needed. In theory, maximum immune ablation by autologous hematopoietic stem cell transplantation (HSCT) can induce a remission.

[CD11b and CD62L receptors expression on neutrophils after laparoscopic versus open cholecystectomy].

Unlabelled: The development of immunology correlated with surgery enables close recognition of multiple mechanisms responsible for more frequent complications observed after open surgical procedures than after minimally invasive operations.

Objective: Evaluation of selected elements of non-specific immunity in patients undergoing open cholecystectomy (OC) versus laparoscopic cholecystectomy (LC).

Material And Methods: 30 postmenopausal females with non-complicated cholecystolithiasis were analysed.

[Thoracic sympathectomy performed by videothoracoscopic technique].

Unlabelled: Thoracic sympathectomy is a method for a segmental elimination of functions of the sympathetic system by the excision of its Th2-Th3 ganglia. The procedure can be performed both using open and videoscopic technique.

Objective: The purpose of the study was the evaluation of efficacy of videoscopic thoracic sympathectomy.
