    Noni fruit is widely consumed in tropical regions of Indonesia to the Hawaiian Islands. The noni plant has a long history of use as a medicinal plant to treat a wide variety of ailments including CNS disorders. The present investigation was designed to evaluate the antipsychotic effect of noni fruits (Morinda citrifolia Linn.) using mouse models of apomorphine-induced climbing behaviour and methamphetamine-induced stereotypy (licking, biting, gnawing and sniffing).

    This paper reports the characteristics and psychopathology of alcohol dependents with alcohol induced psychotic disorder admitted to the Seremban Hospital. The method is that of a case study of all alcohol dependents with alcohol induced psychotic disorder admitted to the Psychiatric Ward, Hospital Seremban over 3 years (1993-1995). There were 34 subjects, 30 Indians, 3 Chinese and 1 Malay with a mean age of 43 years. 32 were men and predominantly of Social Class IV and V (91%). They had a mean duration of drinking of 14.2 years and had a mean weekly consumption of 69.5 units of alcohol. There was a family history of alcohol dependence in (44%). The majority (68%) consumed samsu with beer the second choice. Auditory hallucinations (26) and delusions (16) were common while visual hallucinations (3) and depression (2) were less frequent. Speech disorder occurred in 4 subjects. 2 developed delirium tremens and 1 died. Liver function test was normal in 55%. All except the death from delirium tremens responded to treatment with a combination of anxiolytics, thiamine and antipsychotics and were rapidly discharged. The mean stay was 7 days. However, (68%) did not return for follow up and only 4 were abstinent from alcohol at the time of follow up.

    Creatine kinase (CK) is an enzyme that is found widely in muscle tissues. Raised levels would occur when there is muscle damage. Raised levels are used as one of the diagnostic criteria for Neuroleptic Malignant Syndrome (NMS). This study looks at CK levels in 30 psychotic inpatients without NMS and compares them with 10 patients with NMS. It was found that 67% of the patients without NMS had raised CK levels, 20% of whom had levels in excess of 1000 IU/L. The rest had a two to five-fold increase over normal limits. Raised levels were associated with the use of intramuscular injections and physical restraints, situations which are well known to result in muscle injury. All the NMS patients had raised CK levels but 40% had levels below 1000 IU/L. Our findings support the idea that CK levels, though helpful, should be interpreted with care as raised levels are nonspecific.

    We present a patient with topiramate-induced psychosis who developed alternative psychosis following temporal lobectomy. The number of surgical candidates for temporal lobectomy is increasing as is the frequency of psychiatric co-morbidities. Preoperative planning should take account of these psychiatric co-morbidities. In particular, precautions should be taken when antiepileptic drug-induced psychosis occurs, as this could predict the occurrence of alternative psychosis following lobectomy.

    Anticholinergic burden (ACB) from medications impairs cognition in schizophrenia. Cognition is a predictor of functional capacity; however, little is known about ACB effect on functional capacity in this population. This study assesses the relationship between ACB and functional capacity across the life span in individuals with schizophrenia after controlling for ACB effect on cognition. A cross-sectional analysis was performed with data collected from 6 academic tertiary health centers. Two hundred and twenty-three community-dwelling participants with schizophrenia or schizoaffective disorder were included in this study. Main variables were ACB, antipsychotic olanzapine equivalents, functional capacity, cognition, and negative symptoms. Simultaneous linear regression analyses were performed to assess the association between ACB, functional capacity, and cognition and then between ACB and cognition. A mediation analysis was then performed to examine whether cognition mediated ACB effect on functional capacity if there was an association between ACB and cognition. Mean age of participants was 49.0 years (SD = 13.1, range 19-79), and 63.7% of participants had severe ACB, ie, a total score of 3 or above. Regression analyses revealed that ACB, age, education, and cognition independently predicted functional capacity and that ACB predicted cognition among those aged 55 years and older. Mediation analysis showed that cognition did partially mediate the effect of ACB on functional capacity in this older cohort. In conclusion, people with schizophrenia are exposed to severe ACB that can have a direct negative impact on functional capacity after controlling for its impact on cognition. Reducing ACB could improve functional capacity and potentially real-world function in schizophrenia.

    Nineteen acutely disturbed psychotic Asian patients were treated with a single intramuscular injection of 50 mg of zuclopenthixol acetate in Viscoleo. Patients were assessed clinically before and after treatment using the Brief Psychiatric Rating Scale (BPRS). Serum zuclopenthixol and the inactive geometric isomer trans(E)-clopenthixol were determined by high-performance liquid chromatography after intramuscular injection. All patients improved, with the BPRS being significantly reduced (p < 0.001) at 72 h after injection. Adverse effects were generally few. The mean +/- SEM serum zuclopenthixol concentrations at 24, 48, and 72 h were 19.9 +/- 2.8, 31.5 +/- 4.5, and 17.8 +/- 2.9 micrograms/L, respectively. trans(E)-Clopenthixol concentrations ranged from negligible to 39.5 micrograms/L. This study confirms that a single intramuscular injection of 50 mg is adequate for managing severely disturbed psychotic patients for the first 3 days. The serum zuclopenthixol concentrations attained in the Asian patients were higher than those reported in Caucasian psychiatric patients. In some patients, a considerable amount of zuclopenthixol had been transformed to trans(E)-clopenthixol.

    The psychiatric morbidity following hysterectomy has received increasing attention. One of the sequelae of hysterectomy has been a brief, acute psychosis with excellent outcome, the etiology and pathomechanism of which is still unclear. Two Chinese patients born of Southeast Asian origin who manifested brief, acute psychosis following hysterectomy are presented. Therapy comprised drug treatment with low dose antipsychotics and benzodiazepines coupled with hypnosis and marital therapy to explore and treat the underlying pathology. Both psychotic states resolved. Follow-up at 12 months revealed stable mental condition in one subject; however, the second patient was lost to follow up. The impact of the womb's removal is explored in the context of the ethnicity of the patients and their sociocultural background.

    OBJECTIVE: To examine the prescription rates in cancer patients of three common psychotropic drugs: anxiolytic/ hypnotic, antidepressant and antipsychotic.

    MATERIALS AND METHODS: In this retrospective cohort study, data were extracted from the pharmacy database of University Malaya Medical Center (UMMC) responsible for dispensing records of patients stored in the pharmacy's Medication Management and Use System (Ascribe). We analyzed the use of psychotropics in patients from the oncology ward and cardiology from 2008 to 2012. Odds ratios (ORs) were adjusted for age, gender and ethnicity.

    RESULTS: A total of 3,345 oncology patients and 8,980 cardiology patients were included. Oncology patients were significantly more often prescribed psychotropic drugs (adjusted OR: anxiolytic/hypnotic=5.55 (CI: 4.64-6.63); antidepressants=6.08 (CI: 4.83-7.64) and antipsychotics=5.41 (CI: 4.17-7.02). Non-Malay female cancer patients were at significantly higher risk of anxiolytic/hypnotic use.

    CONCLUSIONS: Psychotropic drugs prescription is common in cancer patients. Anxiolytic/hypnotic prescription rates are significantly higher in non-Malay female patients in Malaysia.

    Schizophrenia is one of the most expensive psychiatric illnesses. This study compared retrospectively health-care resources consumed 12 months before and 24 months after risperidone long-acting injection (RLAI) treatment in Hong Kong. A mirror-image analysis was conducted using data (N=191) from three public hospitals in Hong Kong from 2003 to 2007. The main outcome measure was hospitalisation cost. Other secondary outcomes such as hospitalisation episodes, outpatient visits and adverse events were also compared. A predictive model was established using linear regression based on generalised estimating equations. Analysis showed that RLAI was associated with a reduction in hospitalisation cost by HK$10,001,390 (24.7%) (HK$40,418,694 vs. HK$30,417,303; P-value <0.05). Days of hospitalisation were reduced by 1538 days (10.1%) (15,271 vs. 13,733; P-value <0.05). The predictive model estimated that the hospitalisation cost of patients using RLAI was only 11.1% (3.1-3.93%, 95% confidence interval (CI)) compared to those receiving conventional antipsychotics combined with oral risperidone. Cost of hospitalisation was significantly reduced after RLAI therapy. However, results should be considered as indicative or suggestive only, due to potential channelling bias where certain drug regimens are preferentially prescribed to patients with particular conditions. The findings from our study may be useful in health-care decision making considering treatment options for schizophrenia in resource-limited settings.

    BACKGROUND: The objective was to investigate the occurrence and characteristics of oculogyric spasm (OGS) in an Asian country.

    METHOD: All 2035 Asian (88% Chinese, 7% Malays and 5% Indonesians) psychiatric in-patients in the state psychiatric hospital in Singapore were surveyed for occurrence of oculogyric spasm (OGS) over a two-month period.

    RESULTS: Thirty-four patients (1.7%) developed OGS (53% male and 47% female). All the 34 patients had been on maintenance antipsychotic drugs for more than five months. Eighteen patients had recurrent attacks. The mean chlorpromazine equivalent daily dose for those patients with recurrent OGS was 511 mg. This was significantly higher (P < 0.05) than the 277 mg daily dose received by those without recurrent OGS. Most (68%) of the attacks occurred between 1400-2000 h suggesting that OGS may have a diurnal variation.

    CONCLUSIONS: OGS presenting as tardive dystonia may be due to a relative increase in cholinergic activity.

    BACKGROUND: Very few data are available to demonstrate the economic benefit of early paliperidone palmitate once-monthly long-acting injectable (PP1M) treatment in patients with schizophrenia or schizoaffective disorder.

    METHODS AND MATERIALS: This study has retrospectively compared the healthcare utilization and associated costs of pre- and post-PPIM treatment in 413 patients with schizophrenia or schizoaffective disorder recruited from three major public hospitals providing psychiatric services in Hong Kong. Patients were categorized into early treatment (≤3 years since diagnosis) and chronic (>3 years) groups, and also whether they were receiving polypharmacy (POP).

    RESULTS: It was found that patients who were started on early therapy with no POP had the most favourable outcomes. Overall results of the entire cohort, including both early and late treatments, indicate that there was a slight increase in annual in-patient days (IP) per patient and outpatient visit (OP) by 3.18 and 1.87, respectively, and a decrease in emergency room visit (ER) of 0.9 (p
