Bracing of Pectus Carinatum in Children: Current Practices.

Background: Although effective, compressive orthotic bracing (COB) in children with pectus carinatum is still not standardized. This study has aimed to analyze current practices amongst members of the Chest Wall International Group (CWIG).

Methods: A web-based questionnaire was mailed to all CWIG members at 208 departments.

Varied onset of heart ventricular depolarization in different age groups of healthy volunteers.

Group mean isopotential maps of initial parts of ventricular depolarization (QRS complex) in 4 age groups (10, 14, 19 and 22 years) of young healthy subjects, females and males, were analyzed using different increments between isopotential lines. It was found that the increment 0.1 mV masks some features of the maps, which are seen only by smaller increment (0.

Model-based calculation of thyroid gland normal tissue complication probability in head and neck cancer patients after radiation therapy.

Aim: Primary hypothyroidism is one of the late complications that can occur after radiation therapy for malignant tumors in the head and neck region. The aim of this retrospective study was to show the validity of the Lyman-Kutcher-Burman (LKB) normal tissue complication model for thyroid gland based on clinical results.

Methods: Thyroid function was evaluated by measuring thyroid-stimulating hormone and free thyroxine serum levels before radiation therapy, 3 months after the beginning of radiation therapy, and afterwards at each follow-up visit.

Central Systolic Hypertension in Patients with Well-Controlled Hypertension.

. Central systolic blood pressure (CSBP) has prognostic significance and simplified devices for its estimation have been introduced recently. The aim of this study was to assess the achievement of the target CSBP in treated hypertensive patients.

ST segment body surface isointegral maps in patients with arterial hypertension.

In this retrospective study we analysed changes of the ST segment in patients with arterial hypertension using multi-lead body surface mapping of the electric heart field as the ST segment often shows non-specific changes and is influenced by many different conditions. We constructed isointegral maps (IIM) of chosen intervals (the first 35 ms, the first 80 ms, and the whole ST segment) in 42 patients with arterial hypertension (with and without left ventricular hypertrophy) and in the control group involving 23 healthy persons. We analysed the position and values of map extrema.
