[IN-FAMILY VIOLENCE IN CONNECTION WITH HEAVY DRINKING]

BÁCSKAI Erika, GEREVICH József

[The interdisciplinary question of in-family violence has been being researched for a long time. The major part of this problem is related to the connection between heavy drinking and infamily violence. The background of its importance can mainly be found in all of those social, economic and personal losses and expenses, which result in the number of missed working hours, the costs of sanitary, police, judicial, punishment cases, nonmaterial harms and personal tragedies. Considering that the question of in-family violence related to alcohol consumption has never been a subject to systematic research in Hungary, Research Institute of Addictology made an attempt to analyse the alcohological relations of in-family violence in course of the research project called 'Violent behaviour in family patients treated with alcohol problems in the domestic abuse'. Detailed plan of the research can be found on the webpage of the institute (www.adki.hu). Within the scope of this project we first surveyed the international technical literature of in-family violence. When editing the themes we worked according to the so-called Mendeleyev-table, which means the collection of technical literature from (mainly American) full-text databases accessible on the Internet while putting the possible themes into logical order.]

[THE POSSIBILITIES OF USING PROBIOTICS IN DIGESTIVE DISEASES]

DEMETER Pál

[The mammalian intestinal tract contains a complex, dynamic and diverse society of microorganisms. The beneficial effects of developing a normal bacterial flora are: colonic resistance against pathogens, immunmodulation and intact intestinal barrier. Probiotics are live microbial supplements which beneficially affect the host by improving its intestinal microbial balance after oral administration. The health benefits of probiotics have been the subject of increased research interests. This paper gives a review of the literature that study the roles of probiotics in the prevention and treatment of antibiotic-associated diarrhea, traveller's diarrhea, irritable bowel syndrome, inflammatory bowel disease, Helicobacter pylori infection and hepatic encephalopathy. In human studies the examined probiotics are safe, tolerable and seem to be effective in conditions of diarrhea caused by antibiotics, traveller's diarrhea and pouchitis. In other above-mentioned conditions further randomized and controlled clinical trials are needed to evaluate their efficacy. Based on these results, in the research and manufacturing of genetically-engineered probiotic bacteria a major leap is expected.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

[Effect of two month positive airway pressure therapy on the structure of sleep, cognitive function and anxiety]

CSÁBI Eszter, VÁRSZEGI Mária, SEFCSIK Tamás, NÉMETH Dezsõ

[Obstructive sleep apnea is a common disorder, characterized by repeated episodes of upper airway obstruction during sleep, resulting intermittent hypoxia and disruption of the normal sleep pattern, which caused cognitive dysfunction in these patients. Nasal continuous positive airway pressure is the treatment of choice for this disorder. The aim of the study is to evaluate the effect of short-term positive airway pressure on sleep pattern (polisomnographic measures), cognitive function and anxiety. Twenty four newly diagnosed and previously untreated patients with obstructive sleep apnea were evaluated a battery of neuropsychological tests before and after 2 and a half months of the treatment. We focused on working memory, short and long-term episodic memory, executive functions, anxiety and subjective sleepiness. Our results showed that the two and half month of treatment improved the respiration during sleep, sleep pattern and the subjective sleepiness. We found improvement in short- and long-term verbal memory, and complex working memory. Despite of treatment we did not find improvement in visuospatial learning. These results reveal that 2 and a half months of positive airway pressure treatment restored not only the normal respiration during sleep and normal sleep pattern, but also the cognitive functions. Our study suggests that cognitive dysfunction is at least partial reversible in obstructive sleep apnea patients after positive airway pressure treatment.]

Restless leg syndrome frequency in health workers

ÖCAL Ruhsen, ATGÜDEN Gizem, AYCAN Cagri, BALABAN Zeynep, SENAR Seran, YAVUZ Sena

Introduction - Restless Leg Syndrome (RLS) is a disease, primarily composed of sensational symptoms, caused by the urge to move lower extremities especially at night, and characterized by undesired feelings of the legs. Decreasing of the dopaminergic effect at night is thought to be responsible from these symptoms. RLS patients suffer from low quality of sleep affecting their daily life activities even causing socio-economic loss. Although RLS is a common and treatable disease, it can not be diagnosed easily due to the variability of symptoms. Aim - The purpose of this study is to determine the frequency of RLS among health workers and to define the disease causing factors. Method - A questionnaire was applied to 174 randomly selected health workers at Baskent University Medical Faculty (KA17/285). The demographic information, history of illnesses or usage of drugs, socioeconomic status, working hours and daytime sleepiness were questioned. Included in the questionnaire were diagnostic criteria for RLS, frequency assessment scale, and survey of sleep quality. We used “the diagnostic criteria of international RLS working group” for the diagnosis, and “Pittsburgh sleep quality index survey” to determine the quality of sleep. Reliability and validity studies were performed on both tests. Results - A significant relationship between socio-economic status and RLS was found (p<0.05) as an increase of RLS frequency in parallel with decreased socio-economic status. RLS was found to be common among health workers. We suggest that health workers should be checked regularly, and they should be informed about the disease in order to raise an awareness and hence increase their quality of life.

[Bacterial contamination and irritable bowel syndrome]

NOVÁK János

[Irritable bowel syndrome (IBS) is one of the most common gastrointestinal condition, which affects 10-15% of adults in developed countries. Recent observations have raised the possibility that disturbances in the gut microbiota and/or the accompanying low-grade inflammatory state might contribute to the etiology and symptomatology of irritable bowel syndrome. Some studies indicate that small intestinal bacterial overgrowth (SIBO), as confirmed by hydrogen breath tests (HBT), is more prevalent in patients with irritable bowel syndrome than in matched controls without IBS. Although the data are conflicting, this observation has led to the hypothesis that bacterial contamination was the primary cause of IBS. As a consequence of this hypothesis, a lot of therapeutic options have found their way into the armamentarium of those who treat patients with IBS. These agents include probiotics, prebiotics, antibiotics and anti-inflammatory agents. This paper describes the various mechanisms by which changes in the gut flora might contribute to IBS and also discusses the efficacy and safety of antibiotic therapies, especially rifaximin, for treating IBS/SIBO symptoms.]

[Sleep disordered breathing and epilepsy: relationships and therapeutic considerations]

FALUDI Béla, BÓNÉ Beáta, KOMOLY Sámuel, JANSZKY József

[The importance of the sleep related breathing disorders (obstructive sleep apnea syndrome, central sleep apnea, and Cheyne-Stokes breathing) in the pathophysiology crebro- and cardiovascular disorders is well known. The relationship of sleep related breathing abnormalities and epilepsy is also important but underestimated in the daily practice. The relation is bidirectional. The breathing abnormalities in sleep may play important role in generating epileptic seizure, but the adverse effect of seizure and antiepileptic therapy (generation of apneas and hypopneas) may worsen the seizure control. The effect of new therapies (vagal nerve and deep brain stimulation) on the sleep architecture and sleep disordered breathing must be examined and discussed. Here we present a brief case of epileptic patient with deep brain stimulation therapy on sleep as well. The examination of the sleep related breathing abnormalities in epilepsy patient may help improve the effectiveness of antiepileptic therapy.]
