Divorce and life in singe-parent households is almost always a stressful period in children's lives. Conduct disorder and suicidal behavior represent a desperate cryfor help. Conclusion Most adolescents in both groups live in single-parent households. These young people have frequently passed into adolescence with little reason to feel that they could rely on their parentsfor support, or on their home as a place of sanctuary.

Objective: To report a case of a patient treated with clozapine who developed pericarditis with pericardial effusion that resolved when the drug was discontinued. Method: Case report of a 21-year-old man with psychotic disorder that had been stable on clozapine therapy for five months (after failure of atypical antipsyhotic agents) presented to the emergency department complaining of chest pain and progressive shortness of breath that had lasted for a few days. Echocardiography showed a pericardial effusion suggestive of a cardiac tamponade, and the fluid was removed by pericardiocentesis. All other possible causes of the pericardial effusion were ruled out and clozapine was suspected as the most likely explanation. Clozapine was discontinued and the patient's symptoms improved markedly. Discussion: According to the Naranjo probability scale, clozapine is a probable cause of pericarditis. Although clozapine is a known cause of myocarditis and cardiomyopathy, there are only several reports in the literature describing clozapine-induced pericarditis and pericardial effusion. In our patient, the pericardial effusion cleared within several days following clozapine discontinuation. Conclusion: There have been only a few cases of clozapine-induced pericarditis reported in the literature, however this adverse effect of clozapine can occur, as this case report clearly demonstrates. Cardiac adverse effects of clozapine are potentially life threatening, hence early recognition is essential to prevent serious outcomes.

Introduction. Parkinson's disease is the second most common neurodegenerative disease with as many as 50-70% of patients experiencing psychotic symptoms during the course of the illness. Our aim was to provide an evidence-based review on the etiology, prevalence and management of psychotic symptoms in Parkinson's disease. Material and Methods. We used references from the "Medline" database published from 1999 to 2019. Results. The most common psychotic symptoms in Parkinson's disease are visual hallucinations, which occur in 25-30% of patients, acoustic hallucinations in about 20%, and delusions in around 5% of these patients. The etiology of psychotic symptoms is not fully clarified, but researchers suggest a complex interrelationship of factors associated with the disease itself and the factors associated with antiparkinsonian medications. After exclusion of other etiologic causes of psychotic symptoms, it is necessary to revise the type and dose of antiparkinsonian drugs. Although pimavanserin has recently been approved by the United States Food and Drug Administration, the current treatment of choice for psychotic symptoms in Parkinson's disease is still quetiapine. Only patients who do not tolerate or do not respond to quetiapine are treated with clozapine, which has been proven more effective, but with significant side effects. Conclusion. Timely diagnosis and adequate treatment of psychotic symptoms in Parkinson's disease are essential, because they dramatically affect the quality of life of patients and their families. Therefore, it is necessary to establish more effective tools for screening and treatment of psychotic symptoms in Parkinson's disease.
