Significant differences were observed concerning such parameters and left atrial dilatation (LAD, cm) in subgroup B (LAD 4.63 sd 0.72 p = 0.0003; EF 58.52 sd 9.97, p = 0.01; PAP 44.58 sd 11.59, p = 0.05) compared to A (LAD 4 sd 0.41; EF 64.4 sd 8.65; PAP 37.2 sd 6.11). Significant correlations were found between haematological and echocardiographic parameters. Our data highlight the key role of early identification of cerebrovascular patients with a wider due to restricted therapeutical window because of cardiovascular dysfunctions.

The consequences of the influence of those factors are determined by the type, intensity and duration of the events, level of the child's development at the time of exposure to those events. The analysis of the speech and language impairment of the children with the physical and mental disability has found speech and language impairments in 63.69% of the sample. The largest number of children with speech and language impairments was found in the categories of mental retardation, multiple disabilities and deafness. A large number of children were born with the problem such as too low weight and length at birth, or the pregnancy itself was irregular. The mothers of these children usually had certain complications in their pregnancies and complications at birth. Some of the children have or had HIC, HIE, hyperbilirubinemia and certain infec...

Aim: To determine the presence of certain risk factors, especially smoking, and the occurrence of speech and language disorders (SLD) in patients with stroke (S). Methodology: We analyzed the data of 290 patients affected by stroke: age, gender, present RF, especially smoking, type of stroke and the presence of SLD from the medical history. Results: The average age of the patients was 69.23. 35.51% of patients were 65 and younger. Male gender prevailed in the sample (56.2%:43.8%). The average time since stroke onset was 33.95 days. 92.80% of the sample had some of the RF. There were 45.17% of patients with two or more RF. There were 40.34% patients with SLD and 59.66% had not registered SLD. Most patients had ischemic stroke (80.30%). 40.77% of patients in this group had SLD. 11.0% were with hemorrhagic stroke. 31.25% of patients in this group had SLD. The combination of ischemic and hemorrhagic stroke had 3.40% of the sample and in this group SLD was present in 60.00%. 1% of the sample had SAH. There were 26.20% smokers, both temporary and ex-smokers. The average age of smokers was 63.78, and of non-smokers 71.35. In the group of smokers 46.34% patients had SLD, whereas in the group of non-smokers 38.01% patients had SLD. Conclusion: The largest part of the sample had a presence of some RF, most often a combination of two or more factors. Smoking had significantly influenced the earlier occurrence of stroke. There is a higher percentage of SLD smoker patients in comparison with non-smokers.

Purpose this study was to compare the results of success solving riddles in patients with left body side impairments and right-sided brain damage after a stroke and subjects of control group. Methods: We tested a group of patients with left body sided impairments. Sample had 120 subjects, 60 patients after stroke and control group were 60 people without stroke with similar gender, age and educational structure. Results: A sample of patients with stroke had the average age of 65.85 years. Control sample was approximately the same in age structure of the participants. The average performance of the group with stroke was 31.00%, and the control group 52.86% successfully solved riddles. The task is contained 43 riddles in total. We specifically analyzed the set of riddles where control group had the success rate of 85% or more riddles solved. The group of patients who suffered a stroke had a success rate of 61.3% riddles solved in that same set of riddles. Conclusion: Although patients who suffered a stroke did not have damage to the parts of the brain responsible for speech and language function, most of the patients with left body side impairments and right-sided brain damage showed a below-average ability to solve riddles in comparison to the control group without brain damage.

Cilj rada se bazirao na utvrđivanju rezultata govornojezičke rehabilitacije pacijenta N. N. sa prisutnom senzornom afazijom nastalom usljed moždanog oštećenja izazvanog padom niz stepenice. Metodologija se zasnivala na praćenju uspješnosti rehabilitacije tokom četiri mjeseca. Procjena uspješnosti vršena je Bostonskim dijagnostičkim testom za afazije (BDAE). Prikaz bolesnika: Tokom rehabilitacije pacijenta najviše smo se oslanjali na djelimično očuvanu sposobnost čitanja što nije specifično za ovaj tip afazije. Prva procjena govornojezičkih sposobnosti nije u potpunosti vjerodostojna zbog narušenog opšteg stanja pacijenta, pomućene svijesti i drugih okolnosti zbog čega je rehabillitacija prekinuta. Nakon poboljšanja opšteg stanja, izvršen je ponovni prijem pacijenta i obavljena je logopedska procjena, te je istom utvrđeno da je kod pacijenta prisutna senzorna afazija, ali uz specifičnost u vidu djelimično očuvane sposobnosti čitanja što je iskorišteno tokom rehabilitacije. Procjena je vršena četiri puta u periodu od 4 mjeseca. Nakon ponovnog prijema logopedski tretman se provodio stacionarno, svakodnevno u trajanju od mjesec dana, a nakon otpusta iz ustanove tretman je nastavljen u okviru porodice a prema povremeno dobijenim uputama od logopeda. Na početku rehabilitacije na subtestu auditivnog razumijevanja govora Bostonskog dijagnostičkog testa za afazije, pacijent je postigao minimalne rezultate, dok je pri posljednjem testiranju na kraju rehabilitacije postigao značajno uspješnije rezultate u svim segmentima auditivnog razumijevanja. Zaključak: Dobrom procjenom govorno jezičkog statusa, planiranjem rehabilitacije, kontrolnim praćenjem toka rehabilitacije, podsticanjem, motivisanosti pacijenta, te uključivanjem porodice u rehabilitaciju u ovom prikazu slučaja postignuti su dobri rezultati u rehabilitaciji afazije. Ključne riječi : senzorna afazija, Bostonski dijagnostički test za afazije (BDAE), rehabilitacija govora i jezika, čitanje. Summmary: Introduction: Rehabilitation of aphasia depends on the localization, severity and extent of brain damage, length and intensity of rehabilitation, patient age, motivation, family support and environment, material conditions and other factors. Aim: Aim of the paper was to determine the outcomes of speech-language rehabilitation of patient N.N. with sensory aphasia resulting from brain injury caused by a fall down the stairs. The methodology was based on follow up of theoutcomes of speech rehabilitation for more than four months. We used the Boston Aphasia Diagnostic Test (BDAE). Case reaport: During patient's rehabilitation, we relied mainly on partially preserved reading ability, which is not specific to this type of aphasia. The first assessment of speech and language skills is not fully credible due to the poor general condition of the patient, the blurring of consciousness and other circumstances that cause the rehabilitation to be interrupted. After improving the general condition, the patient was readmitted, and the speech therapist performed an assessment and the patient was found to have sensory aphasia, with specificities in the form of partially preserved reading ability, which was used during rehabilitation. The assessment was performed four times over a 4-month period. After the patient's re-arrival, a speech therapy was performed at the hospital for a month, and after discharge from the institution, treatment continued in the family, occasionally following the instructions of the speech therapist. At the beginning of rehabilitation in the BDAE speech subtest, the patient achieved minimal results, while at the end of rehabilitation he achieved significantly more

Radom se želi utvrditi povezanost lokacije moždane lezije nakon MU sa sposobnošću razumijevanja govora i jezika kod bolesnika oštećene komunikacije. Veliĉina ispitivane grupe je 135 bolesnika. Korišćen je subtest procjene razumijevanja govora Boston Diagnostic Aphasia Examination (BDAE) tokom prva dva mjeseca nakon MU. Prosjeĉna starost ispitivane grupe je 66,8 godina. Veća je zas-tupljenost muškog pola. Lezije mozga su locirane na 35 lokalizacija. Sposobnost auditivnog razumijevanja rijeĉi i jezika je u prosjeku 61,5%; auditivnog razumijevanja dijelova tijela 66,55%; razumijevanja naloga 59,11%; razumijevanje kompleksnog ideacionog materijala 51,91%. Najbrojniji pacijenti uzorka su bili pacijenti sa le-zijama lijeve velikomoždane hemisfere koji su ujedno postigli i najslabije rezultate. Najzastupljenije su bile le-zije lijeve hemisfere lokalizovane: frontotemporalno, frontoparijetotemporalno, parijetotemporalno, temporalno, " zone irigacije ACM " , temporookcipitalno, frontoparijetalno, frontalno i insula. Rezultati auditivnog razumije-vanja govora i jezika zavise od lokalizacije moždane lezije. Bolesnici sa oštećenjem temporalnog režnja izolova-no ili u kombinaciji sa oštećenjima susjenih regija postigli su najslabije rezultate. Ključne reči: afazija, moždani udar, lokacija moždanog oštećenja, govorni poremećaji Summery: Damages of speech caused by stroke (stroke) reduce ability to express and understand speech, reading and writing. Aim of the research is to determine the relationship between brain lesion location after stroke, with ability to understand speech and language in patients with damaged communication. The sample is 135 patients. For estimation of understanding of speech Boston Diagnostic Aphasia Examination (BDAE), during the first two months after the stroke, was used. The average age of patients was 66.8 years. Males are prevalent than female. Brain lesions are found at 35 locations. Capacity for auditory comprehension of words is 61.5% in average; auditory understanding of body parts is 66.55%; understanding of orders is 59.11%, and understanding of complex ideational material is 51.91%. The most frequent in the sample were patients with lesions of the left cerebrum hemisphere who also achieved the weakest results. The most frequent were lesions of left hemisphere sites: front temporal, front parietal temporal, parietal temporal, temporal, "area irrigation ACM", temporal occipital, frontal parietal, frontal and insula. Results of auditory comprehension of speech and language depends on the location of brain lesions. Patients with damage to the temporal lobe of the brain, in isolation or in combination with neighboring regions, achieve the lowest test scores.

Objective The aim of the study was to determine the ability to solve riddles in stroke patients who do or do not have speech and language disorders (SLDs), to determine the presence of SLDs in relation to the lesion localization, as well as to define the relationship between riddle-solving and functional impairment of a body side. Methods The sample consisted of 88 patients. The data used included age, sex, educational level, time of stroke onset, presence of an SLD, lesion localization, and functional damage of the body side. The patients were presented with a task of solving 10 riddles. Results A significant SLD was present in 38.60% of the patients. Brain lesions were found distributed at 46 different brain sites. Patients with different lesion localization had different success in solving riddles. Patients with perisylvian cortex brain lesions, or patients with Wernicke and global aphasia, had the poorest results. The group with SLDs had an average success of solved riddles of 26.76% (p = 0.000). The group with right-sided functional impairments had average success of 37.14%, and the group with functional impairments of the left side of the body 56.88% (p = 0.002). Conclusion Most patients with SLDs had a low ability of solving riddles. Most of the patients with left brain lesions and perisylvian cortex damage demonstrated lower ability in solving riddles in relation to patients with right hemisphere lesions.

Zakljuĉak: Najveći broj djece sa dijagnozom NRS najvećim dijelom se nalazi na kašastoj i teĉnoj ishrani, iako je prosjeĉna starost uzorka 3,13 godina. Preko trećine uzorka je pri ishrani ovisna o tuĊoj pomoći. Ključne riječi: neuroriziĉna simptomatologija, hranjenje, ovisnost o tuĊoj pomoći, oralna motorna kontrola, manipulativna spretnost. Summary: Introduction: Children who are in the antenatal, perinatal, or postnatal period exposed to the effects of risk factors are classified as children with high-risk neurological symptoms. These children often have psychomotor development disorders and they may have feeding difficulties among other problems. The aim of this research was to observe feeding independence in children with high-risk neurological symptoms involved in the rehabilitation process. Methodology: The sample consisted of 55 children with high-risk neurological symptoms during 4 month at the Institute for Physical Medicine and Rehabilitation " Dr. Miroslav Zotović " , Banja Luka. Results: The average age of the sample was 3.13years, ranging from 2 to 5.5 years of age. Sex ratio was 65.5:34.5 in favour of males. 7.3% of the sample patients were on a liquid diet, 52.7% on a mashed diet and 40.00% on a normal diet. As regards feeding independence, 29.1% children from this sample were independent in feeding, 36.4% were partly independent and 34.5% were dependent on others. The average age of children who were on a liquid diet was 3.07, on a mashed diet 2.99 and on a normal diet 3.31 years. The sample consisted of 15 immobile children, 10 children who needed the help of another person or aids and 30 independently mobile children. Conclusion: The largest number of children with high-risk neurological symptoms was on liquid and mashed diets, although the average age of the sample was 3.13 years. Over a third of the sample children depended on someone else's help in feeding. UVOD Glavni elementi razvoja funkcije normal-nog konzumiranja hrane su integritet anatomskih struktura koje uĉestvuju u procesu hranjenja i sazrijevanje centralnog nervnog sistema. Kod novoroĊenĉeta, sve su radnje refleksne i odvijaju se automatski, pa i sam akt hranjenja, koji je pod nadzorom moždanog stabla i ne zahtijeva supra-bulbarnu kontrolu. Razvojem mozga, posebno kor-tikobulbarnog puta, senzorni podražaji iz usne šupljine, jezika i farinksa, prolazeći kroz moždano stablo u srednji i mali mozak, talamus i moždanu koru, stiĉu najveću kontrolu procesom "encefaliza-cije". Tako se odvija neurofiziološka kontrola hranjenja i gutanja, kojom refleksno novoroĊenaĉko hranjenje i gutanje dolazi pod voljnu kontrolu i postaje "zrelo". Proces hranjenja je i nauĉeni raz-vojni proces. To je uĉenje uslovljeno senzornim podražajem iz usne šupljine, razvojem grube i fine motorike, iskustvom, a zavisi i od djetetovog tem
