    We report a case in a young man who developed acute, persistent and painful tongue protrusion followed by swelling for more than 24 hours. He had relapse symptoms of schizophrenia and had recently received a single dose of parenteral haloperidol to manage his agitation. His record showed history of similar event and he has been taking atypical antipsychotic for maintenance. Mental state examination on admission revealed an agitated man with disorganised speech, restricted affect, auditory hallucination and persecutory delusion. His dystonia and oedema improved after 3 days. His mental status also recovered with the maintenance of low-potency antipsychotic and anticholinergic antiparkinsonian medications.

    A young male presented with many years of delusions and hallucinations, with concurrent heroin use and subsequent amphetamine uses. There were no depressive or manic symptoms and psychotic symptoms prior to the amphetamine use. After the trials of two atypical antipsychotics and later clozapine due to treatment resistance, adherence and functionality were poor and there was still persistent drug use. As a result, a long acting injectable adjunct was commenced, but only minimal effects were observed. However after initiation of directly observed treatment of clozapine with methadone, there has been functional and clinical response and drug use has ceased.

    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.

    A 38-year-old man with an underlying psychiatric illness presented with altered sensorium and abnormal behaviour. He was febrile at 38°C and weak looking; otherwise no other abnormalities were detected. A blood film conducted for malarial parasite (BFMP) revealed Plasmodium falciparum; hence a diagnosis of cerebral malaria was made. He was treated with antimalarial drugs for 2 days prior to being transferred out to the ward following clinical improvement. He subsequently developed episodes of stupor and refusal of feeding. Following an evaluation by the psychiatrist, a diagnosis of catatonic schizophrenia was made and he was started on oral sulpiride and benhexol. Unfortunately, he developed high-grade fever at 40°C with muscle rigidity and fasciculation. The diagnosis of neuroleptic malignant syndrome (NMS) was clinched and the antipsychotics were discontinued. However he succumbed to NMS several days later due to multiorgan failure.

    OBJECTIVE: The objective of this study is to determine the prevalence of metabolic syndrome among schizophrenia patients receiving antipsychotic monotherapy in Malaysia.
    METHOD: A cross-sectional study was conducted at multiple centres between June 2008 and September 2011. Two hundred and five patients who fulfilled the DSM IV-TR diagnostic criteria for schizophrenia and who had been on antipsychotic medication for at least one year, were screened for metabolic syndrome. Patients receiving a mood stabilizer were excluded from the study. Metabolic syndrome was defined by using the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults Treatment Panel III (ATP III) modified for Asian waist circumference.
    RESULTS: In the first-generation antipsychotic (FGA) group, the highest prevalence of metabolic syndrome was among patients treated with trifluoperazine and flupenthixol decanoate (66.7% each). For the second-generation antipsychotic (SGA) group, the highest prevalence of metabolic syndrome was among patients treated with clozapine (66.7%). The component with the highest prevalence in metabolic syndrome was waist circumference in both FGA and SGA groups except for aripiprazole in SGA.
    CONCLUSION: The prevalence of metabolic syndrome in schizophrenia patients receiving antipsychotic monotherapy in Malaysia was very high. Intervention measures are urgently needed to combat these problems.

    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.

    The hydroquinone and catechol like metabolites, NCQ344 and NCQ436 respectively, of the antipsychotic remoxipride have recently been demonstrated to induce apoptosis in myeloperoxidase (MPO)-rich human bone marrow progenitor and HL-60 cells [S.M. McGuinness, R. Johansson, J. Lundstrom, D. Ross, Induction of apoptosis by remoxipride metabolites in HL-60 and CD34+/CD19- human bone marrow progenitor cells: potential relevance to remoxipride-induced aplastic anemia, Chem. Biol. Interact. 121 (1999) 253-265]. In the present study, we determined the molecular mechanisms of apoptosis induced by these remoxipride metabolites in HL-60 cells. Our results show that apoptosis was accompanied by phosphatidylserine (PS) exposure, activation of caspases-9, -3, -7 and DNA cleavage. In HL-60 cells treated with the hydroquinone NCQ344 and catechol NCQ436, the general caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp. fluoromethyl ketone (Z-VAD.FMK) blocked DNA cleavage and activation of caspases-9, -3/-7. In addition, PS exposure was significantly but not completely inhibited by Z-VAD.FMK. These results demonstrate that although Z-VAD.FMK inhibitable caspases are necessary for maximal apoptosis induced by NCQ344 and NCQ436, additional caspase-independent processes may orchestrate changes leading to PS exposure during apoptosis induced by the remoxipride polyphenolic metabolites.

    INTRODUCTION: Despite the high prevalence of sexual dysfunction among male schizophrenia patients, there is still a paucity of research on this area.
    AIMS: The study aims to determine the prevalence of sexual dysfunction and any association between male patients with schizophrenia in remission and the sociodemographic profile, medication, depression, anxiety, psychopathology of illness, body mass index, and waist circumference.
    METHODS: A cross-sectional study with nonprobability sampling method was conducted in a psychiatric outpatient clinic in Taiping Hospital (Perak, Malaysia) over a 7-month period. A total of 111 remitted male schizophrenia patients were recruited. The validated Malay version of the International Index of Erectile Function (Mal-IIEF-15) was administered to the patients and assessed over 4-week duration in the domains of erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Logistic regression analysis was employed.
    MAIN OUTCOME MEASURES: Prevalence and associated factors for sexual dysfunction in each domain are the main outcome measures.
    RESULTS: All five domains of sexual functioning in patients showed a high prevalence of dysfunction ranging from 78.4% to 97.1% with orgasmic dysfunction being the least impaired and intercourse satisfaction the worst impaired. Among the domains, only orgasmic dysfunction was significantly associated with race, i.e., Chinese at lower risk for impairment than the Malays (OR = 0.23; 95% CI: 0.07, 0.76; P = 0.018); education, i.e., patients with education higher than primary level were at higher risk for dysfunction (OR = 6.49; 95% CI: 1.32, 32.05; P = 0.022); and Positive and Negative Syndrome Scale (PANSS)-positive subscale, i.e., higher PANSS-positive score was a protective factor for orgasmic dysfunction (OR = 0.54; 95% CI: 0.33, 0.89; P = 0.015).
    CONCLUSIONS: The prevalence of sexual dysfunction was generally high. Malay patients and those with education higher than primary level were at higher risk for orgasmic dysfunction whereas higher PANSS-positive score was protective against the impairment. The high rate of sexual dysfunction in schizophrenia patients warrants a routine inquiry into patients' sexuality and the appropriate problems being addressed.

    AIM: Quality of life has recently been emphasized in the management of schizophrenia, yet data from developing country is lacking. We explored the differences in subjective quality of life between conventional antipsychotics (CAs) and atypical antipsychotics (AAs).

    METHODS: This is a naturalistic study conducted in Kuala Lumpur, Malaysia. Patients with first-episode schizophrenia and related psychosis were recruited from Kuala Lumpur Hospital. WHOQOL-BREF, side effects of medications and other variables were assessed after 1 year of treatment in routine clinical situation.

    RESULTS: The study comprised 120 adults. There were no significant statistical differences between groups concerning subjective quality of life, extrapyramidal side effects and employment. Significant less benzhexol usage was reported among AAs (P<0.001) compared to CAs and sulpiride.

    CONCLUSION: Patients treated with CAs, sulpiride or AAs experienced similar quality of life, clinical and health outcomes after 1 year commencing treatment. Overall, the results are in line with other major pragmatic clinical trials. This study also found sulpiride cost-effective.

    Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing the nosology, pathogenesis and neuropsychiatric aspects in this clinical syndrome. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' i.e. psychodynamic theorists consider it as egodefensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts. We highlight hypersexuality as multi-dimensional involving an increase in sexual activity that is associated with distress and functional impairment. The aetiology of hypersexuality is multi-factorial with differential diagnoses that include major psychiatric disorders (e.g. bipolar disorder), adverse effects of treatments (e.g. levodopatreatment), substance-induced disorders (e.g. amphetamine substance use), neuropathological disorders (e.g. frontal lobe syndrome), among others. Numerous neurotransmitters are implicated in its pathogenesis, with dopamine and noradrenaline playing a crucial role in the neural reward pathways and emotionally- regulated limbic system neural circuits. The management of hypersexuality is determined by the principle of de causa effectu evanescent, if the causes are treated, the effect may disappear. We aim to review the role of pharmacological agents causing hypersexuality and centrally acting agents treating the associated underlying medical conditions. Bio-psycho-social determinants are pivotal in embracing the understanding and guiding management of this complex and multi-determined clinical syndrome.

    Specific ethnic genetic backgrounds are associated with the risk of Stevens-Johnson syndrome / toxic epidermal necrolysis (SJS/TEN) especially in Asians. However, there have been no large cohort, multiple-country epidemiological studies of medication risk related to SJS/TEN in Asian populations. Thus, we analyzed the registration databases from multiple Asian countries who were treated during 1998-2017. A total 1,028 SJS/TEN cases were identified with the algorithm of drug causality for epidermal necrolysis. Furthermore, those medications labeled by the US Food and Drug Administration (FDA) as carrying a risk of SJS/TEN were also compared with the common causes of SJS/TEN in Asian countries. Oxcarbazepine, sulfasalazine, COX-II inhibitors, and strontium ranelate were identified as new potential causes. In addition to sulfa drugs and beta-lactam antibiotics, quinolones were also a common cause. Only one acetaminophen-induced SJS was identified, while several medications (e.g., oseltamivir, terbinafine, isotretinoin, and sorafenib) labeled as carrying a risk of SJS/TEN by the FDA were not found to have caused any of the cases in the Asian countries investigated in this study.

    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.

    AIMS: To determine the most efficacious and acceptable treatments of agitation in dementia.

    METHODS: MEDLINE, EMBASE, PsycINFO, CENTRAL and clinicaltrials.gov were searched up to 7 February 2017. Two independent reviewers selected randomized controlled trials (RCTs) of treatments to alleviate agitation in people with all-types dementia. Data were extracted using standardized forms and study quality was assessed using the revised Cochrane Risk of Bias Tool for RCTs. Data were pooled using meta-analysis. The primary outcome, efficacy, was 8-week response rates defined as a 50% reduction in baseline agitation score. The secondary outcome was treatment acceptability defined as treatment continuation for 8 weeks.

    RESULTS: Thirty-six RCTs comprising 5585 participants (30.9% male; mean ± standard deviation age, 81.8 ± 4.9 years) were included. Dextromethorphan/quinidine [odds ratio (OR) 3.04; 95% confidence interval (CI), 1.63-5.66], risperidone (OR 1.96; 95% CI, 1.49-2.59) and selective serotonin reuptake inhibitors as a class (OR 1.61; 95% CI, 1.02-2.53) were found to be significantly more efficacious than placebo. Haloperidol appeared less efficacious than nearly all comparators. Most treatments had noninferior treatment continuation compared to placebo, except oxcarbazepine, which was inferior. Findings were supported by subgroup and sensitivity analyses.

    CONCLUSIONS: Risperidone, serotonin reuptake inhibitors as a class and dextromethorphan/quinidine demonstrated evidence of efficacy for agitation in dementia, although findings for dextromethorphan/quinidine were based on a single RCT. Our findings do not support prescribing haloperidol due to lack of efficacy, or oxcarbazepine due to lack of acceptability. The decision to prescribe should be based on comprehensive consideration of the benefits and risks, including those not evaluated in this meta-analysis.

    Haloperidol is an antipsychotic drug that exerts its' antipsychotic effects by inhibiting dopaminergic neurons. Although the exact pathophysiology of haloperidol extrapyramidal symptoms are not known, the role of reactive oxygen species in inducing oxidative stress has been proposed as one of the mechanisms of prolonged haloperidol-induced neurotoxicity. In the present study, we evaluate the protective effect of alpha lipoic acid against haloperidol-induced oxidative stress in the rat brain. Sprague Dawley rats were divided into control, alpha lipoic acid alone (100 mg/kg p.o for 21 days), haloperidol alone (2 mg/kg i.p for 21 days), and haloperidol with alpha lipoic acid groups (for 21 days). Haloperidol treatment significantly decreased levels of the brain antioxidant enzymes super oxide dismutase and glutathione peroxidase and concurrent treatment with alpha lipoic acid significantly reversed the oxidative effects of haloperidol. Histopathological changes revealed significant haloperidol-induced damage in the cerebral cortex, internal capsule, and substantia nigra. Alpha lipoic acid significantly reduced this damage and there were very little neuronal atrophy. Areas of angiogenesis were also seen in the alpha lipoic acid-treated group. In conclusion, the study proves that alpha lipoic acid treatment significantly reduces haloperidol-induced neuronal damage.

    BACKGROUND: This study was conducted to determine the impacts of medication adherence on hospitalization and direct healthcare cost in patients with schizophrenia in Thailand.
    METHODS: A retrospective study was undertaken. Patients with schizophrenia aged 18-65 years who visited a University hospital and received antipsychotics from April 2011 to October 2011 were included. Propensity score-adjusted logistic regression was used to determine the impacts of medication adherence on schizophrenia-related and all-cause hospitalizations.
    RESULTS: A total of 582 patients were included. Three out of 224 patients (1.3%) were hospitalized with schizophrenia in optimal adherence group, while 10 of 140 (7.1%) were hospitalized in under-adherence group, and 7 of 218 (3.2%) were hospitalized in over-adherence group. Based on propensity score-adjusted multivariate logistic regression, the adjusted odds ratio was 5.86 (95% confidence interval = 1.53-22.50) for schizophrenia-related hospitalization and 8.04 (95% confidence interval = 2.20-29.40) for all-cause hospitalization. The average annual direct healthcare costs in patients with optimal adherence, under-adherence, and over-adherence were US$371 ± US$836, US$386 ± US$734, and US$508 ± US$2168, respectively.
    CONCLUSION: An initiation of interventions to maintain optimal adherence in patients with schizophrenia would significantly impact the healthcare system.

    Low aqueous solubility is a major problem faced during formulation development of new drug molecules. Lurasidone HCl (LRD) is an antipsychotic agent specially used in the treatments of schizophrenia and is a good example of the problems associated with low aqueous solubility. Lurasidone is practically insoluble in water, has poor bioavailability and slow onset of action and therefore cannot be given in emergency clinical situations like schizophrenia. Hence, purpose of this research was to provide a fast dissolving oral dosage form of Lurasidone. This dosage form can provide quick onset of action by using the concept of mixed hydrotropy. Initially, solubility of LRD was determined individually in nicotinamide, sodium citrate, urea and sodium benzoate at concentration of 10, 20, 30 and 40% w/v solutions using purified water as a solvent. Highest solubility was obtained in 40% sodium benzoate solution. In order to decrease the individual hydrotrope concentration mixed hydrotropic agents were used. Highest solubility was obtained in 15:20:5 ratio of Nicotinamide + sodium benzoate + sodium citrate. This optimized combination was utilized in the preparation of solid dispersions by using distilled water as a solvent. Solid dispersions were evaluated for X-ray diffraction, differential scanning calorimetry and Fourier-transform infrared to show no drug-hydrotropes interaction has occurred. This solid dispersion was compressed to form fast dissolving tablets. Dissolution studies of prepared tablets were done using USP Type II apparatus. The batch L3 tablets show 88% cumulative drug release within 14 min and in vitro dispersion time was 32 min. It was concluded that the concept of mixed hydrotropic solid dispersion is novel, safe and cost-effective technique for enhancing the bioavailability of poorly water-soluble drugs. The miraculous enhancement in solubility and bioavailability of Lurasidone is clear indication of the potential of mixed hydrotropy to be used in future for other poorly water-soluble drugs in which low bioavailability is a major concern.

    Objective: The aim of the study was to determine the early readmission rate among the psychiatric patients discharged from a teaching hospital in Malaysia. The associated factors were also examined. Methods: This is a prospective and observational study. The socio-demographic and clinical data of 202 patients from the psychiatric ward were collected on discharge along with the administration of instruments including Brief Psychiatric Rating Scale (BPRS), Life Events Questionnaire (LEQ), and Multidimensional Scale of Perceived Social Support (MSPSS). Assessment of compliance to medication and substance use was reliant on self-report data. Medication compliance was categorized as “poor” vs “good”, whereas poor compliance was the complete discontinuation of medication for at least two weeks. The patients were followed up to determine whether they were readmitted within 6 months. Results: At the end of 6 months follow-up, 32.2% of the subjects were readmitted. Univariate regression analysis indicated that patients with psychotic disorder, past episodes, previous admission, poor compliance, on conventional or depot injectable antipsychotic and higher BPRS scores on discharge were significantly associated with early readmission (p
