The influence of physiotherapy on improving general state of patients suffering from Multiple sclerosis
ČERVINSKÁ, Klára
The bachelor thesis summarizes present knowledge of the disease Multiple sclerosis and its ways of treatment. The aim of the thesis, is to build up a suitable complex physiotherapeutical treatment, which would have a positive effect on a general state of patients suffering from MS. The thesis consists of two parts. The first part is devoted to etiopathogenesis, symptoms of the illness, diagnostics, pharmacological therapy and the importace of rehabilitation treatment. The second experiential part contains a case study of two patients suffering from different forms of the illness. It describes their present health state, the course of the rehabilitation treatment and its evaluation. Furthermore performed examinations, medical history and a suggestion of a longterm rehabilitation treatment are also presented in this part. The research took place in the Multiple Sclerosis centre in Prague. The effect of the physical therapy was evaluated by measurement of physical condition and a kinesiological analysis. The thesis also involves a questionnaire in which the patients evaluate influence of physiotehrapy on their general state from their point of view. Rehabilitation has an effect on the state of patients particularly in correction of posture, breath stereotype and affecting balance. Physiotherapy helps the patients to influence some of the symptoms of the disease and therefore improve everyday-life activities. However the effect is only shortlasting.

Epidemiology of multiple sclerosis
FOŠUM, Pavel
There are approximately 2.5 million cases of multiple sclerosis [MS] in the world. Each year, around 10,000 new cases of MS are diagnosed. There are approximately 0.1%. in the Czech Republic and that means that there are approximately 15,000 people with this disease. Multiple sclerosis is a progressive neurological inflammatory disease of the central nervous system in pathogenesis. The auto-immune mechanisms are appliedinvolves; both the affect the myelin and damaged axons. This damage is responsible for the permanent disability of MS. The main objective of this thesis was to use quantitative research to describe the occurrence of MS in the Regions of South Bohemia and Usti, and within objective to estimate the true prevalence of multiple sclerosis in the South and the Usti Regions. MUDr. Príkaszký and I used the method of descriptive epidemiological studies on the technique of data collection, as well as the analysis and the comparison of two sources using the double-capture method. As a research area, we used a set of patients with multiple sclerosis. The data were gathered in two regions of the Czech Republic: Usti nad Labem Region and South Bohemia. We investigated the number of patients from neurologists and MS centers in both regions.There is also the data on health insurance included with the Ústí Region in this research. According to the data, we estimated the prevalence of neurologists in South Bohemia to be 79.20 per 100,000 people. The MS Center at the hospital in Ceske Budejovice has registered 512 patients: 388 women and 124 men. The values of the MS Centre in Ceske Budejovice received from the neurologists are a total of 882 patients, which is a prevalence of 138.6 patients per 100,000 of the population. Regarding the Usti Region, the prevalence reported by neurologists is 208.2 per 100 000 people. The MS Center at the hospital in Teplice, has registered 1139 sick 730 women and 409 men. According to health insurance data in their database, of 1187 people listed with a diagnosis of G.35, 333 are men and 854 are women. This represents an estimate of the prevalence 305/100000 of the people who are registered in the NGA. We calculated the prevalence of illnesses from those sources in both of these regions is higher than the general estimates. When comparing the data source of health insurance and the model file from the MS center of Ústí Region, we calculated the overall sensitivity of 91.7% within a health insurance group. The calculation of the estimated prevalence has been reached by using the method of double-capture of those sources that provided an estimate of 2,681 patients in the Usti Region. The models of this data are mainly demonstrated as a possible approach to the estimate of the prevalence of this chronic disease in the case of multiple sclerosis. The information has been obtained from the collection of data. The results of this study can be used by other workers who have the same objective as this study.

Possibilities of managing the situacion when first aid´s crew is attacked
SVITÁKOVÁ, Hana
Abstract Currently media more and more often inform about various attacks, violence, criminal acts or aggression. These are basically types of interpersonal relationships with that we live daily. We may observe such negative aspects of human behaviour even on professional level. That concerns in particular activities of so called assistance jobs. Assistant jobs include but are not limited to services of ambulance providing daily pre-hospitalization emergency health care to patients in acute situations. Number of rescuers who were attacked and injured is increasing. Problematic situation at the place of their response is often not suitably solved by ambulance staff and that makes it difficult to provide good quality care to patients. A quantitative research has been conducted within this Bachelor essay. Data was collected based on responses to questions. The quantitative research has been performed in form of a questionnaire. The subjects of research were ambulance rescuers, response nurses, doctors and ambulance drivers of South Bohemian Ambulance. The research has been performed in April 2008. The Bachelor essay includes two sections, one practical and one theoretical. The purpose of the essay was to map the issue of ambulance crew attacks. The objective has been achieved. The following three hypotheses have been formulated. Hypothesis No. 1: Health rescuers feel to be threatened by patients/clients more than ambulance drivers. This hypothesis has not been confirmed. Hypothesis No. 2: Ambulance doctors feel to be threatened by patients/clients less than health rescuers. This hypothesis has not been confirmed. Hypothesis No. 3: Health rescuers have better self defence skills than nurses working at ambulance. This hypothesis has not been confirmed. Results of the above research are to be published at www.zzsjck.cz. The will form a base for implementation of self defence courses in cooperation with Faculty of Health and Social Studies of South Bohemian University in České Budějovice.
