One of the main challenges of contemporary psychiatry in treating patients with schizophrenia is the early diagnostics and timely prevention of relapse of this disorder. Objective: The goal of the study was to find the potential causes of psychotic episode recurrence and its first symptoms in rehospitalized patients with schizophrenia. Methods: Patients with schizophrenia, who were urgently hospitalized to KUM Psychiatry clinic and had less than three psychotic episodes, took part in the study (N=97). Medical documentation and a structured questionnaire, designed by the authors, were used to evaluate anamnesis data. Results: The main causes of relapse were: willful discontinuation of psychopharmacotherapy (50% of the cases), spontaneous relapses without any clear exogenous cause (20%), and onetime alcohol intoxication (8%). The patients and their family members indicated the following first symptoms of relapse: anxiety, fear (73%), sleep disorders (62%), aggression (52%), delusions and/ or hallucinations (37%). The symptoms tended to occur in combinations rather than individually. Conclusions: Causes and symptoms of schizophrenia relapse differ from patient to patient. It is possible to prevent the relapse knowing the common causes and first symptoms, because most of the patients are able to detect the first symptoms themselves.

Statistical data of recent years evidences that Lithuania is leading in Europe in the suicide rate. Suicide is one of the main causes of death in adolescence. Objective: The goal of the study was to establish the relationship between teenagers' anxiety and depression symptoms and suicidal behavior. Methods: Two groups of teenagers from 14 to 17 took part in the study: the study group (after suicide attempts, N=109) and the control group (no suicide attempts, N=218). Hospital Anxiety and Depression Scale (HADS) was used in evaluating anxiety and depression symptoms. Results: Evaluating adolescents', who attempted suicide, anxiety and depression symptoms according to HADS, no significant differences between genders were determined: anxiety symptoms were determined to 22.8% of girls and 26.9% of boys (χ 2 =3.50, df=2, p=0.2), depression symptoms were determined to 21.1% of girls and 26.9% of boys (χ 2 =1.01, df=2, p=0.6). Evaluating possible impact on teenagers' suicidal behavior, the odds rate was calculated, the chance was determined whether a suicide is possibly attempted. The possibility of suicidal behavior was increased significantly by anxiety and depression symptoms, determined with HADS: 3,9 times more anxiety symptoms (95%, CI 1,6-9,7) and 9,2 times more depression symptoms (95% CI 2,9-29,7) in boys, and in girls, respectively-2,5 times (95%, CI 1,1-5,9) and 7,6 times (95%, CI 2,4-24,8). Conclusions: Anxiety and depression symptoms, according to HADS, may have possible impact on teenagers' suicidal behavior.

Objective: Suicide is one of predominant causes of death among young Europeans. Recent statistical data on suicide proves that Lithuania is one of the leading countries in this domain. The goal of this study is to define and compare the peculiarities of suicidal behavior among teenage boys and girls. Methods: 109 teenagers of the age 14 to 17 years old (52 boys and 57 girls), who were treated in Kaunas University of Medicine Psychiatry Clinic Children-Teenagers' Department after suicide attempts, took part in the study. Medical documentation and structured questionnaire designed by the authors were used. Results: The incidence of suicidal thoughts among teenagers who attempted suicide was compared according to gender. It was determined that almost one fourth of the boys (23,1%) and one sixth of the girls (17,5%) have never thought about committing suicide before they attempted to do that. Almost every other boy (48,1%) and 40,4% of the girls have had suicidal thoughts a few times a year. One fourth of the boys (28,8%) and one third of the girls (36,8%) have had suicidal thoughts a few times per month or per week. And only a few girls (5,3%) still had suicidal thoughts after a suicidal attempt (χ 2 =4,04, df=3, p=0,3). Conclusions: No statistical gender differences were found in estimating the incidence of suicidal thoughts among teenagers who attempted suicide.
