Clinical Features, Psychiatric Assessment, and Longitudinal Outcome of Suicide Attempters Admitted to a Tertiary Emergency Hospital.

The objective of this study was to characterize admissions to an emergency hospital due to suicide attempts and verify outcomes in 2 years. Data were collected from medical records and were analyzed using descriptive statistics and logistic regression. The sample consisted of 412 patients (58.7% women; mean age = 32.6 years old, SD = 14.3). Self-poisoning was the most frequent method (84.0%), and they were diagnosed mainly as depressive (40.3%) and borderline personality disorders (19.1%). Previous suicide attempts and current psychiatric treatment were reported by, respectively, 32.0% and 28.4%. Fifteen patients (3.6%, 9 males) died during hospitalization. At discharge, 79.3% were referred to community-based psychiatric services. Being male (OR = 2.11; 95% CI = 1.25-3.55), using violent methods (i.e., hanging, firearms, and knives) (OR = 1.96; 95% CI = 1.02-3.75) and psychiatric treatment history (OR = 2.58; 95% CI = 1.53-4.36) were predictors for psychiatric hospitalization. Of 258 patients followed for 2 years, 10 (3.9%) died (3 suicide), and 24 (9.3%) undertook new suicide attempts. Patients with a history of psychiatric treatment had higher risks of new suicide attempts (OR = 2.46, 95% CI = 1.07-5.65). Suicide attempters admitted to emergency hospitals exhibit severe psychiatric disorders, and despite interventions, they continue to present high risks for suicide attempts and death.

Are low doses of antipsychotics effective in the management of psychomotor agitation? A randomized, rated-blind trial of 4 intramuscular interventions.

BACKGROUND: Psychomotor agitation can be associated with a wide range of medical conditions. Although clinical practice advocates the use of several drugs for the management of psychomotor agitation, there are still very few controlled studies comparing the profiles of action and the adverse effects of different drugs that induce tranquilization. OBJECTIVES: The purpose of this study was to compare the efficacy and safety of 4 low-dose pharmacological interventions used to control psychomotor agitation guided by the clinical response. METHODS: Using a randomized, rated-blind design, 100 agitated patients were assigned to receive 1 of 4 treatments: haloperidol (2.5 mg) + promethazine (25 mg) (HLP + PMZ), haloperidol (2.5 mg) + midazolam (7.5 mg) (HLP + MID), ziprasidone (10 mg) (ZIP), or olanzapine (10 mg) (OLP). Patients were evaluated just before the intervention and after 30, 60, and 90 minutes, using the Agitation-Calmness Evaluating Scale. Adverse effects were assessed within 24 hours after the intervention, using selected items from the UKU Scale (Ugvalg Klinisk Undersgelser Side Effect Scale). According to the clinical indication, medication could be repeated twice after the first injection. Data were analyzed using general linear model with repeated measures and logistic regression. RESULTS: All treatment options promoted a reduction in agitation, without causing excessive sedation, although a lower reduction in agitation was observed with HLP + PMZ and ZIP compared with HLP + MID and OLZ. The need for an additional dose of medication was observed in 22 patients, and only 8 remained agitated during the entire 90-minute period. A higher risk for the development of extrapyramidal symptoms within the following 24 hours was observed with HLP + PMZ. DISCUSSION: Low doses of haloperidol combined with midazolam can be as effective as olanzapine in reducing psychomotor agitation without increasing the risk of extrapyramidal effects. Because of the higher risk for the occurrence of extrapyramidal symptoms, the combination of haloperidol with promethazine should be considered a second-line treatment option.

Antinuclear antibodies testing as a routine screening for systemic lupus erythematosus in patients presenting first-episode psychosis.

AIMS: This report discusses the use of antinuclear antibody (ANA) detection as a screening test for neuropsychiatry systemic lupus erythematosus (NPSLE) in patients presenting a first-episode psychosis. METHODS: We reviewed the medical records of 85 patients admitted to an emergency service due to first-episode psychosis, during a 1-year period, for whom ANA detection was performed through an IFI HEp2 cell assay. ANA-positive patients were subsequently evaluated for autoantibodies and neuroimaging exams. RESULTS: Three patients presented as ANA positive in the initial screening and further investigation confirmed NPSLE in two patients. The patients were treated with antipsychotics and cyclophosphamide pulses with satisfactory outcomes. CONCLUSION: Even though ANA detection is not specific, it is a low-cost procedure and could be an important screening test for NPSLE in the early-onset psychosis.

[Management of the violent or agitated patient]. / Manejo de paciente agitado ou agressivo.

OBJECTIVE: To review current data about the management of agitated or aggressive patients. METHOD: Through a search of databases (PubMed and Web of Science), empirical articles and reviews about pharmacological and non-pharmacological interventions for the management of agitation and /or violence were identified. RESULTS: The non-pharmacological management of agitation/aggression encompasses the organization of space and appropriateness of behavior and attitudes of health professionals. The main goal of pharmacological management is rapid tranquilization aimed at reducing symptoms of agitation and aggression, without the induction of deep or prolonged sedation, keeping the patient calm, but completely or partially responsive. Polypharmacy should be avoided, and doses of medications should be as small as possible, adjusted according to clinical need. Intramuscular administration of medication should be considered as a last resort and the options for the use of antipsychotics and benzodiazepines are described and commented. The physical management by means of mechanical restraint may be necessary in violent situations where there is risk to the patient or staff, and must meet strict criteria. CONCLUSION: Procedures must be carefully implemented to avoid physical and emotional complications for patients and staff.

Manejo de paciente agitado ou agressivo / Management of the violent or agitated patient

OBJETIVO: Revisar as medidas preconizadas para o manejo de pacientes agitados ou agressivos. MÉTODO: Por meio de uma busca em bancos de dados (PubMed e Web of Science) foram identificados artigos empíricos e revisões sobre intervenções farmacológicas e não farmacológicas para o manejo de agitação e/ou violência. RESULTADOS: O manejo não farmacológico de agitação/agressão engloba a organização do espaço físico e a adequação de atitudes e comportamentos dos profissionais de saúde. O objetivo principal do manejo farmacológico é a tranquilização rápida, buscando a redução dos sintomas de agitação e agressividade, sem a indução de sedação profunda ou prolongada, mantendo-se o paciente tranquilo, mas completa ou parcialmente responsivo. A polifarmácia deve ser evitada e as doses das medicações devem ser o menor possível, ajustadas de acordo com a necessidade clínica. A administração intramuscular de medicação deve ser considerada como última alternativa e as opções de uso de antipsicóticos e benzodiazepínicos são descritas e comentadas. O manejo físico, por meio de contenção mecânica, pode ser necessário nas situações de violência em que exista risco para o paciente ou equipe, e deve obedecer a critérios rigorosos. CONCLUSÃO: Os procedimentos devem ser cuidadosamente executados, evitando complicações de ordem física e emocional para pacientes e equipe.

Estudo retrospectivo de uma populaçäo de pacientes atendidos em um ambulatório de seguimento pós-alta psiquiátrica de um hospital-escola: II- Aspectos clínicos / Retrospective study of an outpatient population followed at the post-discharge psychiatric service of a university hospital: II - Clinical aspects

O objetivo do presente trabalho foi a realizaçäo de um estudo preliminar da assistência que tem sido oferecida no Serviço de Seguimento Pós-Alta do Ambulatório de Clínica Psiquiátrica do Hospital das Clínicas da Faculdade de Medicina de Ribeiräo Preto-USP, através do levantamento de alguns dados clínicos de uma populaçäo amostral. A partir de uma populaçäo inicialmente composta pelos pacientes atendidos no Serviço no período compreendido entre janeiro de 1988 e dezembro de 1990, da qual foram levantados dados demográficos em um estudo prévio, foi obtida uma populaçäo amostral de 50 pacientes, escolhida aleatoriamente, porém de maneira estratificada. Os dados foram obtidos através dos prontuários médicos desses pacientes. Observou-se, para a populaçäo estudada, ocorrer um período de internaçäo muito variado, situando-se entre 11 e 60 dias; seguimento ambulatorial por um tempo médio inferior a seis meses, existindo porém dados significativos de seguimento por tempo superior a um semestre, a maioria dos pacientes apresentando a média de um retorno po mês. Muitos dos prontuários näo continham informaçöes suficientes sobre as condiçöes do paciente por acasiäo da alta no Ambulatório. Grande parte deles recebeu alta por abandono, tendo sido observada uma correlaçäo entre tempo prolongado de seguimento ambulatorial e patologias mais graves. Pode-se concluir que näo há, ou näo está sendo seguida, uma padronizaçäo para o tipo de atendimento oferecido nesse Serviço ambulatorial, contrariando os preceitos teóricos que deveriam nortear a assistência em um Hospital-Escola
