[Objective - Obstructive sleep apnea syndrome (OSAS) without treatment can cause serious cardiovascular, cardiorespiratory, neurological and other complications. Family physicians have an important role in recognizing the disease. The aim of the study is to assess the knowledge and attitude of family physicians related to sleep apnea. Whether OSAS screening is realized during the general medical checkup for drivers. Methods - In the cross-sectional study we used a validated OSAKA questionnaire in mandatory continuous medical education courses, supplemented with four additional questions. Results - 116 family physicians and 103 family medicine residents filled out the questionnaire. Hungarian family physicians, especially male doctors lack the adequate knowledge of sleep apnea. The average score of female physicians was significantly higher than that of males (13.4±1.8 vs. 11.7±2.6, p=0.005). The more sprecializations the doctor has, the higher the score. Zero or one special examination holders reached 12.5±2.3 points, two special examination holders 12.7±2.2 points. three or four special examination holders reached 14.0±2.1 (p=0.05). Residents’ average score was 12.1±2.4 points, which is higher than that of family doctors (p=0.012). Female residents also had higher average points than male residents (12.6±2.0 vs. 11.3±2.7; p=0.008). The size, location and type of the practice or the doctor’s age did not show any statistically significant correlation with the number of points achieved. According to our regression analysis, corrected to variables in the model, we found correlation between gender and medical knowledge, but there was no correlation between age, number of specialities, body mass index and the theoretical knowledge of the doctors. In terms of attitude female GPs had higher average scores than male GPs (3.5±0.6 vs. 2.9±0.6, p<0.001). Despite the modification of the 13/1992 regulation only 39% of the practices carried out regularly the required OSAS screening as part of the medical examination for a driving licence. Conclusions - Despite the high prevalence and clinical importance of OSAS, GPs often do not recognize sleep apnea and they have difficulty in treating their patients for this problem.]

Procedural learning and its consolidation in autism spectrum disorder


Children with autism spectrum disorder (ASD) show altered learning and memory. A number of recent studies have debated whether procedural learning in ASD is intact or not. Our aim was to further assess the question of whether the implicit, non-conscious form of procedural learning in ASD children is intact or not, furthermore, how shifts towards a more explicit, attention-demanding task setting can alter this performance. We administered a modified version of the Alternating Serial Reaction Time (ASRT) Task to children with ASD and IQ- and age-matched typically developing (TD) children. The task consisted of alternating blocks of cued (explicit) and uncued (implicit probe) blocks, and was repeated after a 16-hour delay. We found that ASD and TD children showed similar sequence-specific learning in cued explicit blocks, however, on the uncued probe blocks ASD children performed better compared to TD children. After the 16-hour delay both groups showed retention of the previously acquired knowledge. Finally, when we investigated the performance in different parts of the blocks, we found that ASD children did not show an effect of fatigue by the second part of the blocks. Our results suggest that children with ASD have increased implicit procedural learning skills compared to TD children. Differences in cued (explicit) and uncued (implicit) settings indicate that children with ASD are not affected by the lack of explicit instructions in probe blocks, suggesting a resistance for changes in task settings. These findings can help in a more thorough planning of cognitive therapeutic setups for ASD children.

Surveillance and management of patients with tuberous sclerosis complex

FOGARASI András, GYORSOK Zsuzsanna, BODÓ Tímea

Tuberous sclerosis complex (TSC) is an autosomal dominant disease due to the uncontrolled differentiation, proliferation, and migration of cells in several organs. Clinical expression is highly variable, from mild skin findings and asymptomatic brain lesions to seizures, mental retardation, autism, and potentially fatal kidney, cardiac, or pulmonary disease. Aim of this paper is to summarize the diagnostic criteria, surveillance and therapeutic issues of this multisystemic disorder emphasizing the most important neurological consequences. Presenting the state-of-the-art management recommendations and comparing them with the local protocols, we hope that our review might help in the proper assessment of one of the most important single gene disorder.

Electrophysiological alterations and general toxic signs obtained by subacute administration of titanium dioxide nanoparticles to the airways of rats

HORVÁTH Tamara, PAPP András, KOVÁCS Dávid, KÁLOMISTA Ildikó, KOZMA Gábor, VEZÉR Tünde

Introduction and aims - Particles of titanium dioxide (TiO2) with typical size below 100 nm have gained a broad range of application by now, partly involving direct human exposure. Their known properties - high specific surface, mobility within the organism, induction of oxidative stress, release of inflammation mediators etc. - raise the possibility of nervous system damage but the available data regarding this are scarce and contradictory. Based on that, and the experiences with other metal oxide nanoparticles, the aim of the present study was to investigate certain general end nervous system toxic effects of TiO2 nanoparticles applied in the airways of rats. Materials and methods - Young adult Wistar rats (5 groups of 10 rats each) received, daily for 28 days, intratracheal instillations of titanium dioxide nanoparticles of ca. 10 nm diameter, suspended in 1% hydroxyethyl cellulose dissolved in phosphate-buffered saline, in the doses of 1, 3, and 10 mg/kg b. w. Vehicle controls received the suspension medium and there was also an untreated control group. During treatment, the rats’ body weight was measured, and their clinical state observed, daily. After the 28 days, spontaneous cortical activity, sensory evoked potentials and tail nerve action potential was recorded in urethane anesthesia, then the rats were dissected and tissue samples were taken for Ti level determination and biochemical measurements of some oxidative stress indicators. Results - The two higher doses reduced the rate of body weight gain significantly. Sensory evoked potentials and tail nerve action potential were significantly slowed, but the change in the spectrum of spontaneous cortical activity was not significant. Correlation of moderate strength was found between certain evoked potential parameters and brain Ti level and oxidative stress data. Conclusion - Our results underlined the possible neurotoxicity of TiO2 NPs but also the need for further investigations.

Pazopanib induced unilateral posterior reversible encephalopathy syndrome

ARSLAN Beyza Muhsine, BAJRAMI Arsida, DEMIR Elif, CABALAR Murat, YAYLA Vildan

Posterior reversible encephalopathy syndrome (PRES) is a reversible clinical and neuroradiological syndrome which may appear at any age and characterized by headache, altered consciousness, seizures, and cortical blindness. The exact incidence is still unknown. The most commonly identified causes include hypertensive encephalopathy, eclampsia, and some cytotoxic drugs. Vasogenic edema related subcortical white matter lesions, hyperintense on T2A and FLAIR sequences, in a relatively symmetrical pattern especially in the occipital and parietal lobes can be detected on cranial MR imaging. These findings tend to resolve partially or completely with early diagnosis and appropriate treatment. Here in, we present a rare case of unilateral PRES developed following the treatment with pazopanib, a testicular tumor vascular endothelial growth factor (VEGF) inhibitory agent.

[Relationship between sport and traumatic brain injury - risks and sequelaes]

TAMÁS Viktória, KOVÁCS Noémi, BÜKI András

[Traumatic brain injury represents major public health problem worldwide. A typical form of brain injuries is the injury suffered during sports, which according to severity ranges from mild injuries to fatal damages. The significance of the sport related minor head injuries derives form the high incidence, the excessive involvement of the younger age groups, and their potential repetitive nature. The repeated mild head injuries may accumulate, leading to complex structural, neurochemical, neuroendocrine, and psychological alterations, which in long term may result in changes of the patients quality of life and in significant deterioration of participation in the everyday activity. Actually we neither have enough knowledge about the ne-gative consequences, nor the way of prevention, or protection against the harmful long term results. With this study summary we would like to draw attention to the potential hazards emerging from sport injuries, moreover we would like to emphasize the importance of study participation and follow up of articles in this field.]

[Nursing documentation related to attitudes and the management of time spent on administrative activities]

OLÁH Mónika

[Aims of the study: The aim of the study was to explore how did the institutes manage to achieve the legal requirements related to nursing documentation since the introduction of the law. The other aim was to determine the conditions of effective application of the nursing documentation. Sample and methods: Qualitative and quantitative methods were applied as well. In a quantitative, cross-sectional study a questionnaire survey was performed involving 150 nurses. By the means of retrospective data analysis 200 closed nursing documentation were examined. The data analysis was carried out with SPSS 17.0 statistical software. The level of significance was set to p<0.05. Results: The nursing documentation is not personalized (p<0.01) and its information content is not sufficient to learn about the patient’s condition at the time of admission and to evaluate the effects of nursing on the state of the patient. The personalization and information content strongly depends on the nurses’ attitude towards the administration process. Conclusions: As the theory and practice of the nursing documentation are not in accordance, it is necessary to define the principles more precisely and to survey and reorganize the existing documentations. ]

[Neurological aspects of some sleep disorders]


[My aim is to examine the relation between some sleep disorders and neurological diseases; to analyse their mutual interactions in order to achieve new practical data for clinical use. In the theoretical part I summarise some main points of sleep physiology concentrating on the associations of sleep regulation and neurological diseases. In my examinations, besides clinical methods, the most important tools used are sleep analyses performed by polysomnography and MESAM IV as well as brain imaging methods. To assess clinical state of my stroke patients I utilised NIH Stroke Scale. I found pathological sleep apnoea frequency in more than half of the patients in any type (bleeding/infarction) of acute stroke. In a prospective study, sleep apnoea parameters remain permanent during 3 months in the ischaemic group; on the other hand, sleep apnoea improves during follow up after brain haemorrhages. I showed pathological sleep apnoea frequency in myasthenia gravis among male patients without daytime respiration complaint. I looked for the link between the mechanism of the sleep disorder and the underlying organic lesion in two cases. In this analyses I took into account the function of the affected structure in sleep regulation. I found a basal forebrain tumour, affecting sleep regulating centres underlying severe insomnia and I suggest a neurovascular compression of the lateral preoptic area of the hypothalamus being the reason of sleep related painful erection, a parasomnia of unknown origin.]

[In patients on dialysis, the results of studies examining the association of sleep disorders and inflammation are controversial. We assessed the association between inflammatory markers and different sleep disorders in a large sample of kidney transplant recipients. In the cross-sectional study 100 randomly selected kidney transplanted patients underwent one-night polysomnography [“SLeep disorders Evaluation in Patients after kidney Transplantation (SLEPT) Study”] to diagnose obstructive sleep apnea (OSA) and periodic limb movement is sleep (PLMS). Athens Insomnia Scale (AIS) was used to assess the prevalence of insomnia. Socio-demographic information, data on medication, comorbidity and laboratory parameters were collected. Inflammatory markers such as Creactive protein (CRP), serum albumin, white blood cell count, interleukine-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels were measured. The mean age was 51±13 years (43% female) and the prevalence of diabetes 19%. We found no significant difference in the levels of inflammatory markers between patients with OSA and PLMS versus (vs) patients without such disorders. Apnea-hypopnea index showed a significant association with white blood cell count (rho=0.23), and weak, non significant correlations with the other inflammatory markers (rho<|0.15|). PLM index showed weak, non significant correlations with all markers of inflammation (rho<|0.15|). The serum IL-6 level was significantly higher in patients with insomnia (AIS≥10) than in non-insomniacs [median (IQR): 3.2 (2.6-5.1) vs. 1.7 (1.2- 2.9) ng/l; p=0.009]. The levels of other inflammatory markers were similar between insomniacs and non-insomniacs. We did not find any association between the presence of objectively assessed sleep disorders and inflammatory markers in kidney transplant patients.]

[The aim of our study was to examine thestereotypes about female doctors and howdo the female medical students perceivethe working female doctors whom are theirrole models. In the first study (247 from theAlbert Szent-Györgyi Medical and Pharma-ceutical Centre at the University of Szegedand 256 from the Medical and HealthScience Centre of the University ofDebrecen) the female medical students’professional socialization was compared tothe male counterparts’. In the second study(from University of Szeged, 214 femalemedical students, 132 female jurist stu-dents) female medical and jurist students'professional socialization was comparedincluding the comparison of stereotypes inconnection with working female doctorsand jurists. Female medical students’ professionalsocialization is different that of male coun-terparts in several aspects: being morealtruistic, more family centered, gettingcommited to the profession earlier, havingmore ambiguous carrier planes, and asmaller percentage of their parents’ has adegree or is a medical doctor, then for malemedical students. The female medical doc-tor has positive, idealistic, altruistic charac-ters according to both female studentgroups’ opinions. The female doctor’simage is more often associated with char-actersitics implying problems by femalemedical students then jurists. The unfold-ing image of these stereotypes is a femaledoctor who is willing to help, however,faceing lots of hardnesses during work.If the female medical students’ image of theproblematic life of these idealistic femaledoctors’ is known, it provides an opportu-nity to prepare them for the hardnessesthey’ll face avoiding role conflicts andhealth problems in the future.]

[Sleep disorders and quality of life in patients after kidney transplantation]

TURÁNYI Csilla Zita, ZALAI Dóra, MOLNÁR Miklós Zsolt, NOVÁK Márta, MUCSI István

[Kidney transplantation provides the best outcomes, concerning morbidity, mortality and health related quality of life for patients with end stage renal disease. Health related quality of life is increasingly recognized as an important outcome measure in patients with different chronic medical conditions, including chronic kidney disease. Sleep disorders, such as insomnia, sleep apnea syndrome and restless legs syndrome are common in patients with chronic kidney disease. The prevalence of insomnia and restless legs syndrome is similar in kidney transplanted patients to the prevalence observed in the general population. On the other hand, the prevalence of sleep apnea is considerably higher, about 30%. The association between sleep disorders and impaired health related quality of life has been relatively well documented in dialysis patients but only scarce information has been published about the kidney transplanted population. In this paper we summarize published data about sleep disorders and also about their association with health related quality of life in the kidney transplanted population.]
