The purpose of this study was to investigate suicidal behavior among young people in an Asian community. Tracing records of all patients below 21 years of age who attempted suicide and were managed in a teaching hospital, the authors found the incidence increased sixfold between 1991 and 1995. Young females of Indian origin were found to be a risk group. Differences in suicidal behavior among the three main ethnic communities appear to be influenced by various sociocultural factors. The most common diagnosis was adjustment disorder stemming from interpersonal losses and conflicts. Schizophrenia, alcohol, and other substance abuse were rarely reported.

The aim of this study was to find out the agreement between psychiatrists and emergency department (ED) doctors in the diagnosis and treatment of psychiatric emergencies. All patients presenting with a psychiatric complaint and who were subsequently referred to the psychiatrist were included. A standard form was used to collect demographic data, provisional diagnoses and initial treatment by ED doctors, diagnoses by psychiatrists, and compatibility of ED diagnoses and treatment as judged by consulting psychiatrists. The mean age of the 223 patients enrolled was 36.5 years and the distribution between males and females was roughly equal. The most frequent presentations were aggressive behaviour (27.9%), depressive mood (13.5%) and suicidal idea (12.1%). Schizophrenia (39%) was the most common diagnosis followed by depression (20%) and adjustment disorders (9.5%). The agreements between psychiatrists and ED doctors in diagnosis and treatment were 61.4% and 89.5% respectively. Schizophrenia and bipolar disorders were least likely to be mis-classified. It is concluded that ED doctors were deficient in the diagnosis of psychiatric conditions especially in the less common diagnostic categories.

Relationships between service satisfaction, life satisfaction, and self-reported mental health status were examined for Iowa Medicaid mental health service recipients. Of the 16,579 persons who received services in 1993, a mail-out survey was sent to 2,520 persons and returned by 815 (32.3 percent). Persons with schizophrenia reported greater service satisfaction and life satisfaction than persons with other diagnoses, and their ratings of their mental health were higher. A relationship between service satisfaction and current life satisfaction was observed for persons with schizophrenia, affective disorder and adjustment disorder, but not for persons with anxiety disorder.

Whether the Psychopathology Inventory for Mentally Retarded Adults (PIMRA) could detect specific psychopathological disorders was investigated in 652 subjects with different levels of mental retardation living in the community or in residential facilities. An exploratory factor analysis was carried out to check the scale organization of PIMRA. The Anxiety, Adjustment Disorder, Somatoform Disorder, and Soundness Scales were confirmed by 4 corresponding factors; the Psychosexual Disorder Scale was replaced by a factor specific to gender identity problems, and the Schizophrenia Scale by two factors concerning isolation and bizarre behaviors, respectively. The items of the Depression Scale were distributed over the three factors concerning anxiety, adjustment, and psychosomatic disorders, while the items of the Personality Disorder Scale were scattered over almost all the factors. Moreover, 55 subjects with anxiety disorders and 49 with depression were compared to 50 control subjects of the same age, intelligence level, and gender ratio but without dual diagnosis and obtained significantly higher factorial scores both on the overall scale and on the factors specifically related to their disorders. PIMRA has been found to show good construct validity. These results could be considered particularly valid as they were obtained from a large sample comprising different levels of mental retardation and thus showing all possible psychopathological behaviors.

The study aims to determine the psychological profile of suicide ideators, attempters and completers in a tertiary care teaching hospital. A total of 260 suicidal ideators, 58 attempters and 55 completers were studied. The majority of ideators, attempters and completers were 26-35 years of age, males (except attempters who were predominantly females), married, literate up to high school, employed (ideators) or housewives (attempters and completers). The suicide ideators, attempters and completers who had a past history of attempt were 6.9%, 24.1% and 18.2% respectively. Family history of attempted suicide or completed suicide was also common among patients suffering from depression. In suicidal ideators, mixed anxiety and depressive disorder was the most common psychiatric diagnosis followed by major depression and schizophrenia. Among suicide attempters, adjustment disorder with depression was the most common diagnosis. The most common method of suicide attempt was organophosphorus compound intake whereas in suicide completers, the most common method in use was hanging. The patients with suicidal ideation or attempt need careful evaluation, early intervention and long term follow up.

Several lines of evidence suggest a dysregulation of the adrenocortical (HPA) system with hypersecretion of CRH is associated with suicidal behavior. However, controversial results have emerged from the determination of corticotropin-releasing hormone (CRH) concentrations in the lumbar cerebrospinal fluid (CSF) of suicide attempters probably due to methodological differences. We simultaneously measured CRH concentrations in the CSF and in the plasma of 41 psychiatric in-patients with different diagnoses (affective disorder, schizophrenia, personality disorders, adjustment disorder, substance abuse) and eight neurological control subjects. We also measured plasma cortisol concentrations because data from animal experiments suggest that cortisol may influence CSF CRH concentrations. The major finding was that patients who attempted suicide prior to admission had significantly lower CSF CRH concentrations than psychiatric patients without suicidal behavior. CRH concentrations were significantly higher in the CSF than in plasma in both, psychiatric patients and neurological control subjects. There was no significant difference between suicide attempters and patients with acute suicidal ideations. The latter group showed a trend towards lower CSF CRH concentrations compared with the neurological control subjects. Patients with affective disorder alone as well as patients with multiple diagnoses, but not schizophrenic patients, showed significantly lower CSF CRH concentrations than neurological control subjects. Plasma CRH and plasma cortisol concentrations did not differ among diagnostic groups or between suicide attempters vs. non-attempters. Further studies with more homogeneous samples, drug-free patients and with simultaneous assessment of various parameters of the HPA system are warranted.

This investigation examined self-reported psychopathology in a school-based sample of 456 suicidal and nonsuicidal adolescents. The sample consisted of four groups: three at-risk for suicidal behavior based on current suicidal ideation as assessed by the Suicidal Ideation Questionnaire (SIQ; Reynolds, 1988), past suicide attempts, or both; and one nonsuicidal comparison group. Psychopathology was examined using ten scales from the Adolescent Psychopathology Scale (APS; Reynolds, 1998a) including: Major Depression, Conduct Disorder, Substance Abuse, Schizophrenia, Adjustment Disorder, Anorexia Nervosa, Borderline Personality Disorder, Obsessive-Compulsive Personality Disorder, Schizotypal Personality Disorder, and Avoidant Personality Disorder. Analyses were conducted separately for males and females using a MANOVA design that examined psychopathology severity among the four groups. Adolescents who engaged in past or current suicidal behavior had higher psychopathology severity scores compared to their nonsuicidal peers. Males with current suicidal thoughts who had attempted suicide had the highest levels of psychopathology severity compared to males in the other three groups. Females with a past suicide attempt or current suicidal ideation had higher psychopathology severity scores compared to nonsuicidal females. Results show greater psychopathology in school-based adolescents who have engaged in past and/or current suicidal behavior. The need for clinicians and mental health professionals working with at-risk youth to focus on concurrent psychopathology along with suicidal behavior is discussed.

Antipsychotic drugs are used to treat a wide variety of child psychiatric disorders characterized by psychotic symptoms, aggression, excitement, tics, stereotypies and hyperactivity nonresponsive to other therapies. Unfortunately, typical antipsychotics have many adverse effects limiting their long-term use. Novel antipsychotics with combined dopaminergic and serotonergic action, such as risperidone, appear to offer better safety and efficacy profiles in controlled studies of adult patients, and therefore appeared as promising pharmacotherapeutic agents in child psychiatry. The purpose of this retrospective chart review was to obtain data on the potential effectiveness and tolerability of risperidone in children and adolescents presenting with a variety of chronic and severe psychiatric disorders who had been unresponsive to previous pharmacological treatments. Charts for 106 children and adolescents (males n = 81 or 76.4%; females n = 25 or 23.6%), presenting with attention deficit and/or hyperactivity disorder (n = 49 or 46.2%), conduct disorder (n = 13 or 12.3%), oppositional-defiant disorder (n = 5 or 4.7%), behavioural problems not otherwise specified (n = 2 or 1.9%), autism (n = 8 or 7.5%), Asperger's syndrome (n = 8 or 7.5%), pervasive developmental disorder (PDD) not otherwise specified (n = 4 or 3.8%), anxiety (n = 6 or 5.7%), depression (n = 2 or 1.9%), dysthymia (n = 2 or 1.9%), schizophrenia (n = 4 or 3.8%), adjustment disorder (n = 1 or 0.9%) and obsessive-compulsive disorder (n = 2 or 1.9%) were reviewed retrospectively to determine the tolerability and potential efficacy of risperidone treatment for a variety of psychiatric disorders. Six subjects also presented with mental retardation. The average length of illness prior to risperidone treatment was 5 years and the average age of risperidone treatment onset was 11 years. The mean daily dose of risperidone was 1.2 mg (range = 0.25 to 8.0 mg). Very few adverse effects were reported. The average length of risperidone treatment was 11 months with the majority (n = 75 or 76%) of patients maintained on risperidone following study termination. Seven cases (6.6%) were missing follow-up data. The majority (n = 78 or 74%) of patients were taking concurrent psychiatric medications, most commonly stimulants for the treatment of ADHD. Clinical global improvements for children and adolescents at the final study visit were marked (n = .37 or 34.9%), moderate (n = .40 or 37.7%), mild (n = 13 or 12.4%), none (n = 12 or 11.3%), or worse (n = 1 or 1%). Three cases (2.9%) were missing clinical improvement data. Results suggest that risperidone may be useful for managing behavioural disturbances and psychotic symptoms associated with a wide variety of childhood psychiatric disorders. For most patients in the study, a combination of risperidone and adjunctive pharmacotherapy was beneficial. Controlled and discontinuation studies of risperidone treatment in children and adolescents with behavioural and psychotic disorders are recommended.

The investigation of biological correlates of suicidal behavior is important in searching for possible changes in neuronal systems activity related to that behavior, so that pharmacological interventions may be proposed, especially in high-risk subjects. In a sample of 111 subjects admitted in a general hospital after suicide attempt, we studied the turnover of neurotransmitters by measuring the urinary output of the main metabolites of serotonin, dopamine and noradrenaline (5-HIAA, HVA, MHPG respectively), as well as serum cholesterol, and compared them to those of a group of 62 healthy controls. Venous blood samples and urine samples were collected within 24 hours of admission. Psychiatric diagnosis was made according to DSM-IIIR criteria and assessment of suicide intent with Beck's Suicidal Intent Scale (SIS). Fifty-four (54) subjects received the diagnosis of adjustment disorder, 25 of depression, 16 of schizophrenia and 16 of personality disorder. Fourteen subjects (14) had employed a violent mode of attempt. Urinary MHPG was found significantly higher in all diagnostic groups compared to controls. No difference was found concerning the excretion of HVA and 5-HIAA. Serum total cholesterol was found significantly lower both in violent and non-violent attempters compared to controls after correcting for age. No difference in serum cholesterol or MHPG was found between violent and non-violent attempts. Serum cholesterol and MHPG correlated negatively, while the correlations between cholesterol and 5-HIAA or HVA were not significant. Our results confirm previous reports of lower serum cholesterol in attempted suicide. They are also indicative of an increased noradrenaline turnover in subjects who attempt suicide, at least within 24 hours after the attempt. Whether this activation precedes or follows the attempt because of the specific stress, can not be answered at present.

The aim of this study was to evaluate the prevalence of suicidal ideation and its correlates in adolescent methamphetamine (MAMP) users. Using the Epidemiological Version of the Kiddie Schedule for Affective Disorders and Schizophrenia, 200 adolescent MAMP users were assessed for suicidal ideation and psychiatric disorders during the preceding year. Demographic variables, family and peer interaction, characteristics of MAMP use, and personality were also evaluated. Factors correlating to suicidal ideation in adolescent MAMP users were analyzed by logistic regression. In the preceding year, 16% of adolescent MAMP users had suicidal ideation, and multiple factors, including illicit drug use among family members, depressive disorder, adjustment disorder, and emotional instability, correlated with suicidal ideation. Multiple factors, including family, psychopathology, and personality correlate with suicidal ideation in adolescent MAMP users. Subjects showing these characteristics should be monitored for suicidal ideation.
