Introduction: Osteoarthritis (OA) is the most common joint disease in the world. At the end stage of the disease, usually when patients cannot handle the pain anymore, the knee replacement surgery is the most common and effective treatment to reduce pain and improve functionality. The effect of preoperative exercise (prehabilitation) for patients undergoing total knee arthroplasty (TKA) is still controversial. Aim: To investigate the effect of prehabilitation on postoperative outcome and compare the results of the intervention with the control group. Material and Methods: This prospective study included 20 patients with a diagnosis of gonarthrosis, aged 48-70, who were randomly allocated to either the intervention group or control. Ten patients (intervention group) underwent a 6-week home-based exercise program before the TKA surgery. All patients were assessed by Knee Score (KS), Function Score (FS), and Body Mass Index (BMI) according to the following schedule: 6 weeks before surgery (for intervention group it meant before the prehabilitation program), just prior to surgery (for intervention group it meant after the prehabilitation program), after the surgery, at 3 rd month, 6 th month, and 12 th month postoperatively. They were all operated by the same surgeon, for the primary total knee replacement (Zimmer NexGen Complete Knee Solution) at the Clinic for Orthopaedics and Traumatology, Clinical Centre University of Sarajevo, from October 2016 to June 2017. Results: There is statistically significant difference for Knee and Function Score between the intervention and control group in testing time: just before surgery–meaning that KS and FS increased after the prehabilitation program. Knee Score was significantly different between the two observed groups postoperatively, 3 months postoperatively and 6 months postoperatively, while the Function Score was not significantly different in that period. Prehabilitation program provides better preoperative KS and FS, and better KS up to 6 months postoperatively. However, 12 months postoperatively there was no significant difference between the intervention and control group for the Knee and Function Score. Conclusion: Prehabilitation brings significant difference regarding the Knee Score in favor of the intervention group preoperatively and up to 6 months postoperatively.

Introduction:Comorbidity of depression and stroke significantly reduces the quality of life of patients after the stroke. Squeal after stroke also determines the quality of life and have impact on the occurrence of depression after the stroke. In our study we investigated the occurrence of depression in patients after different types and subtypes of stroke measured by the Hamilton scale compared to the level of disability measured by NIHSS scale.Goal:The goal was to make a comparative analysis of depression after stroke, according to gender and age, side of the lesion and the severity of neurological deficit.Material and Methods:Material for our work are 210 patients with stroke treated at the Neurology Clinic, Clinical Center of Sarajevo University in 2012, 105 male and 105 female. The mean age of the patients was 67.12±9.5 years. Ischemic stroke was present in 65% cases. There was no statistically significant difference between ischemic and hemorrhagic stroke among genders. In case of hemorrhagic M-56.7%, F-43.3%; ischemic M-48.3%, F-51.7% (chi-square=6.563, p=0.082). Depression was more prevalent among younger patients (52-60 years) with 39.2% then in the group of older patients (61-70 years) with 32% of depressed. In relation to gender there was significantly more patients with depression among women compared to men (63.8:27.2%, chi-square=14.38, p=0.00019). Depression was more frequent in patients with stroke in the left hemisphere medial localization (63%). NIHSS scale average was 16.07 with the minimum of 11 and maximum of 22, F=52.56, p=0.001.Conclusions:We can conclude that depression after stroke is more frequent in younger patients, female patients, patients with localized stroke in the medial left hemisphere and with higher disability score.

4Primary Health Care Center Ilijas, Bosnia and Herzegovina 5 I ntroduction: Stroke is the third leading cause of mortality, disability and dementia, but leading cause of epileptic manifestations in the elderly. Diabetes mellitus as permanently elevated blood glucose, often accompanied by dyslipidemia, is among the leading causes of atherosclerotic alteration in blood vessels and is also increasing in the world. Goal: To determine the existence and predilection of diabetes mellitus and dyslipidemia, in the development of ischemic stroke. Material and methods: During the 2011 are analyzed all people with stroke admitted at the Neurology Clinic. All patients underwent neurological tests and the laboratory test with special emphasis on the value of blood glucose and lipid levels, with brain CT which confirmed the existence of a stroke, EEG and internist examination. Results: During the one-year period the stroke was confirmed in 1184 patients, aged 33-81 years and 37% in the younger age group (up to 50 yrs.). There was 50.67% male and 49.33% female patients. Ischemic stroke was confirmed in 78.0% (56% with thrombotic and 22% with embolic genesis), of which the 32% was lacunar infarcts (up to 1.5 cm) and hemorrhagic in 22% (SAH in 4.8%, and intracerebral hemorrhage in 17.2%). The most frequent risk factors were hypertension 85%, then smoking in 65%, diabetes mellitus in 39.0%, in 27.38% dyslipidemia, previous stroke in 26.69%, in 23.57% arrhythmia In the baseline sample 30.06% of patients had previously diabetes mellitus and in 8.94% the diabetes was diagnosed during hospitalization, while dyslipidemia was known from earlier in 22.0% and in 5.38% cases was detected during the hospitalization. Among treated patients 79.01% survived, while 20.09% have a fatal outcome. Conclusions: Diabetes mellitus and dyslipidemia, along with hypertension and smoking are the leading risk factors for the occurrence of stroke. By timely detection and treatment can be controlled slow atherosclerotic changes in blood vessels and thus prevent stroke.

Technological diseases are diseases of the modern era. Some are caused by occupational exposures, and are marked with direct professional relation, or the action of harmful effects in the workplace. Due to the increasing incidence of these diseases on specific workplaces which may be caused by one or more causal factors present in the workplace today, these diseases are considered as professional diseases. Severity of technological disease usually responds to the level and duration of exposure, and usually occurs after many years of exposure to harmful factor. Technological diseases occur due to excessive work at the computer, or excessive use of keyboards and computer mice, especially the non-ergonomic ones. This paper deals with the diseases of the neck, shoulder, elbow and wrist (cervical radiculopathy, mouse shoulder and carpal tunnel syndrome), as is currently the most common diseases of technology in our country and abroad. These three diseases can be caused by long-term load and physical effort, and are tied to specific occupations, such as occupations associated with prolonged sitting, working at the computer and work related to the fixed telephone communication, as well as certain types of sports (tennis, golf and others).
