Satisfaction with life in a sample of prelingually deaf cochlear implant users with a good command of spoken Polish as the primary language.

Introduction: This study investigated the level of satisfaction with life (SWL) in a group of cochlear implant (CI) users who had been prelingually deaf but were orally educated. They had received one or two CIs (as a child, adolescent, or adult) and were highly competent Polish speakers. This study looked at three factors that may affect SWL - psychosocial, deafness/hearing and communication related, and sociodemographic.

Health-related quality of life in adults with profound postlingual hearing loss before and after cochlear implantation.

Purpose: In clinical trials and everyday medical practice, health-related quality of life (HRQoL) measures are increasingly being used. That is, in addition to the usual biological health assessment, the impact of disease and treatment on the patient's functioning in the physical, mental, and social areas is an important parameter. The aim of this study was to assess HRQoL before and after using a cochlear implant (CI) in adults with profound hearing loss.

Tinnitus and Hearing Survey: A Polish Study of Validity and Reliability in a Clinical Population.

This study investigates the psychometric properties of the Polish version of the Tinnitus and Hearing Survey (THS-POL), which is a tool for evaluating what proportion of patients' tinnitus is due to hearing problems and what proportion is specifically due to the tinnitus. The THS-POL was created using the translation-backtranslation method. Study participants completed the THS-POL twice over a period of 3 days.

Tissue response after implantation of pure titanium and bioresorbable screws in scapula with postoperative irradiation: an experimental study on rats.

Objective: The study focuses on the comparison of tissue reaction to titanium and bioresorbable implants with and without postoperative irradiation on an animal model.

Materials And Methods: Thirty-nine LEW/W rats were randomly assigned to experimental or control groups. One titanium and one bioresorbable screw (poly-L-lactide [PLLA] and L- and D-lactide poly-L/D-lactide [PDLLA]) were implanted into the left scapulas of 24 rats.

Dosimetry audit of radiotherapy treatment planning systems.

In radiotherapy Treatment Planning Systems (TPS) various calculation algorithms are used. The accuracy of dose calculations has to be verified. Numerous phantom types, detectors and measurement methodologies are proposed to verify the TPS calculations with dosimetric measurements.

Energy dependence of radiochromic dosimetry films for use in radiotherapy verification.

Aim: The purpose of the study was to examine the energy dependence of Gafchromic EBT radiochromic dosimetry films, in order to assess their potential use in intensity-modulated radiotherapy (IMRT) verifications.

Materials And Methods: The film samples were irradiated with doses from 0.1 to 12 Gy using photon beams from the energy range 1.
