  ABSTRACT: The objective of this study was to investigate the clinical features of suicide attempts in elderly patients (≥65 years) in Japan. We enrolled 546 patients who attempted suicide and were hospitalized for inpatient treatment. Characteristics were compared between the elderly and non-elderly patients. Compared with the non-elderly group, the incidence of mood disorders was significantly higher and the average length of stay in the intensive care unit and the duration of hospitalization were significantly longer in the elderly group. Elderly patients hospitalized for attempted suicide were more likely to have mood disorders than the non-elderly.

  ABSTRACT: OBJECTIVE: The objective of this study was to investigate the frequency and clinical features of suicide attempts in adults with autism spectrum disorders (ASDs). METHODS: We enrolled 587 consecutive patients aged 18 or over who attempted suicide and were hospitalized for inpatient treatment. Psychiatric diagnoses, suicide attempt frequency and clinical features were compared between ASD and non-ASD patients. RESULTS: Forty-three (7.3%) of the 587 subjects who attempted suicide had ASDs. The incidence of patients with mood disorders was significantly lower (Fisher's Exact Test, P=.043) and that of those with an adjustment disorder was significantly higher (Fisher's Exact Test, P<.001) in the ASD group than in the non-ASD group. The average length of stay at both the hospital and intensive care unit in the ASD group was longer than that in the non-ASD group (z=-2.031, P=.042; z=-2.322, P=.020, respectively). CONCLUSIONS: ASDs should always be a consideration when dealing with suicide attempts in adults at the emergency room.

  ABSTRACT: BACKGROUND: To date, the clinical features between patients in Japan who have attempted suicide by charcoal burning and those who have attempted suicide by other methods in the context of a mental disorder diagnosis as assessed by structured interviews have not been reported. METHODS: We enrolled 647 consecutive patients who attempted suicide and were hospitalized for inpatient treatment. Psychiatric diagnoses, frequency of suicide attempts, and clinical features were compared between charcoal burning and other suicide methods. RESULTS: Twenty of the 647 patients (3.1%) had attempted suicide by charcoal burning. The ratio of men to women was significantly higher by this method compared with that of other methods. The proportion of patients with mood disorders was significantly higher in the charcoal burning group than that in the other methods group. The occurrence of a psychiatric history in patients in the charcoal burning group was significantly lower than that in the other methods group. LIMITATIONS: The study sample was limited to a single hospital. CONCLUSIONS: The results demonstrate the clinical characteristics of patients who attempted suicide by charcoal burning. Therefore, it is necessary to identify the clinical features of patients who have attempted suicide by charcoal burning in Japan.

  ABSTRACT: The purpose of the present study was to provide preliminary data on the usefulness and safety of blonanserin for patients with delirium in the intensive care unit (ICU). The charts of 32 consecutive patients with delirium in the ICU were retrospectively reviewed. These patients were treated with blonanserin. A total of 96.6% had reduction in Memorial Delirium Assessment Scale score. The proportion of patients with side-effects was 24.1%. Blonanserin may be effective and safe in the treatment of delirium in the ICU.
