    Somnambulism or sleepwalking is a sleep disorder of arousal. Compared to in adults, pediatric and adolescent sleep disorders is still under-researched and poorly described. We report the successful use of low dose quietiapine, an atypical antipsychotic, in the treatment of a 15-year-old Indian male who presented with significant somnambulism. To the best of our knowledge, this is the first report on the use of quetiapine for the treatment of somnambulism in the literature. The presence of high voltage delta waves in sleepwalkers has been offered as a possible explanation for the patho-physiology of sleepwalking Quetiapine has been reported to decrease brain delta activity, and we postulate that this may be the mechanism on how it was beneficial for our patient.

    Drug interactions can cause iatrogenic disease. If concurrent medications are taken, the potential exists for a drug interaction to occur. Renewed interest in the topic interactions has been generated by the fatal interactions involving non-sedating histamine H-1 antagonists and the recent intriduction of two therapeutic agents, the selective serotonin reuptake inhibitors (SSRIs) and HIV protease inhibitors, for the treatment of depression and AIDS, respectively. These three therapeutic agents have been implicated in clinically significant drug interactions. The consequences of these interactions vary in clinical significance, extent, and effect. Some interactions are theoretical whereas others may lead to severe iatrogenic adverse experiences including lethal consequences.The purpose of this review is to alert the medical practioner to potential drug interactions that may occur when these drugs are prescribed to patients. The pharmacological basis and clinical signficance of these interactions are reviewed. The pharmacological mechanisms underlying these interactions are illustrative of those that may be involved for many other medications. Doctors should be aware of the potential pitfall that may occur when certain groups of drugs are prescribed with concurrent medications.

    OBJECTIVES: To evaluate the monitoring of metabolic parameters among outpatients maintained on antipsychotic medications in a general hospital setting in Malaysia and to assess the impact of a local monitoring protocol.
    METHODS: By performing a baseline audit of files from a random sample of 300 patients prescribed antipsychotic medications for at least 1 year; we determined the frequency of metabolic monitoring. The findings informed the design of a new local protocol, on which clinical staff was briefed. We re-evaluated metabolic monitoring immediately after implementation, in a small sample of new referrals and current patients. We explored staff perceptions of the initiative with a follow-up focus group, 6 months post-implementation.
    RESULTS: The baseline audit revealed a sub-optimal frequency of metabolic parameter recording. Re-audit, following implementation of the new protocol, revealed improved monitoring but persisting deficits. Dialogue with the clinical staff led to further protocol modification, clearer definition of staff roles and use of a standard recording template. Focus group findings revealed positive perceptions of the initiative, but persisting implementation barriers, including cultural issues surrounding waist circumference measurement.
    CONCLUSIONS: Responding to challenges in achieving improved routine metabolic monitoring of patients maintained on antipsychotics required on-going dialogue with the clinical staff, in order to address both service pressures and cultural concerns.

    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.

    A substantial percentage of patients will have an inadequate response to
    clozapine in treatment resistance schizophrenia. Therefore, different
    approaches need to be considered for managing this group of patients. We
    present a case of a treatment resistant schizophrenia patient who shows poor
    response toward clozapine. Later, he was started with haloperidol. Even
    though antipsychotic superiority of clozapine in relation to haloperidol is
    significant, this patient demonstrated otherwise.

    OBJECTIVE: The study was aimed to evaluate the gender specific response to adherence and occurrence of side effects among schizophrenic patients in Lahore, Pakistan.

    METHODS: A prospective study was performed for a period of 1 year among 180 newly diagnosed schizophrenics, aged 20-60 years to observe the symptoms, medication adherence and side effects. Morisky-Green-Levine Scale was used to evaluate medication adherence, LUNSER for side effects and PANSS to measure positive and negative symptoms. Data were analyzed using SPSS.

    RESULTS: Positive symptoms (Male: Baseline 36.14 vs. endpoint 23.58, Female: 35.29 vs. 23.74) and negative symptoms (Males 27.9 vs. 20.05, Females 28.41 vs. 20.2) of schizophrenia were equally reduced after a follow up of 1 year in both the genders. Male population suffered more accumulative side effects (11.4 in males vs. 6.40 in females), extrapyramidal symptoms such as tardive dyskinesia and tremors (1.21 in males vs. 0.57 in females) and other side effects as compared to women (p ≤ .005). Males were found poorly adherent to antipsychotic treatment than females (93.3% in males vs. 6.7% in females (p ≤ .005).

    CONCLUSIONS: Prescribing practices should not overlook sex specific factors like hormonal changes, altered brain morphology and socioeconomic factors that may be responsible for the difference in the response to the course of schizophrenia.

    Galactorrhoea is non-lactational milk production and it may or may not be associated with prolactinemia1. It causes embarrassment and distress to a schizophrenic patient, especially, if the patient is male. One study in Germany reported that incidence and prevalence of galactorrhoea in schizophrenia are 14% and 19%, respectively2. Although galactorrhoea is not rare in schizophrenic patients, managing and understanding the a etiology can be problematic. In psychiatric patients, antipsychotics can be a cause but other causes need to be ruled out. Galactorrhoea also needs to be differentiated from pathologic nipple discharge which can be due to breast tumours. Usually, galactorrhoea is bilateral, multiductal, and milky, but discharge can be yellow, green or brown3. This case report describes a 32-year old patient with schizophrenia who visited a government psychiatric hospital in Kota Kinabalu, Sabah, Malaysia. This report highlights the clinical challenges to determine the aetiology of galactorrhoea and to manage it in schizophrenics. It raises the following clinical questions: Why a psychiatric patient develops galactorrhoea? How a schizophrenic patient presents with galactorrhoea? What hormonal imbalances are associated with this psychiatric disorder? How should a doctor handle a schizophrenic patient complaining of galactorrhoea? What is the danger of having galactorrhoea in a male?

    BACKGROUND: Explicit potentially inappropriate medications (PIM) criteria are commonly used to identify and deprescribe potentially inappropriate prescriptions among older patients. Most of these criteria were developed specifically for the Western population, which might not be applicable in an Asian setting. The current study summarizes the methods and drug lists to identify PIM in older Asian people.

    METHODS: A systematic review of published and unpublished studies were carried out. Included studies described the development of explicit criteria for PIM use in older adults and provided a list of medications that should be considered inappropriate. PubMed, Medline, EMBASE, Cochrane CENTRAL, CINAHL, PsycINFO, and Scopus searches were conducted. The PIMs were analyzed according to the general conditions, disease-specific conditions, and drug-drug interaction classes. The qualities of the included studies were assessed using a nine-point evaluation tool. The kappa agreement index was used to evaluate the level of agreement between the identified explicit PIM tools.

    RESULTS: The search yielded 1206 articles, and 15 studies were included in our analysis. Thirteen criteria were identified in East Asia and two in South Asia. Twelve out of the 15 criteria were developed using the Delphi method. We identified 283 PIMs independent of medical conditions and 465 disease-specific PIMs. Antipsychotics were included in most of the criteria (14/15), followed by tricyclic antidepressants (TCAs) (13/15), antihistamines (13/15), sulfonylureas (12/15), benzodiazepines (11/15), and nonsteroidal anti-inflammatory drug (NSAIDs) (11/15). Only one study fulfilled all the quality components. There was a low kappa agreement (k = 0.230) between the included studies.

    CONCLUSION: This review included 15 explicit PIM criteria, which most listed antipsychotics, antidepressants, and antihistamines as potentially inappropriate. Healthcare professionals should exercise more caution when dealing with these medications among older patients. These results may help healthcare professionals in Asian nations to create regional standards for the discontinuation of potentially harmful drugs for elderly patients.

    The dopamine hypothesis has earlier dominated the theories for the
    development of schizophrenia based on the early pharmacologic evidence. The
    antipsychotic drugs, among others, is thought to interfere with the function of the
    dopamine D2 receptor (DRD2) resulting in clinical improvement. Accumulating evidence
    suggest the role of epigenetic mechanisms in the pathophysiology of schizophrenia.
    Despite this, specific evidence linking the DRD2 DNA methylation with schizophrenia is
    insufficient mainly due to the poor accessibility and limited brain samples. Of late, new
    data has suggested the global impact of DNA methylation in the development of
    schizophrenia, thus methylation in the peripheral blood could infer changes in the brain.
    The aim of this study was to assess the DRD2 DNA methylation in the peripheral blood of
    schizophrenia.

    BACKGROUND: Blonanserin is a second-generation antipsychotic used for the treatment of schizophrenia. This study determined the efficacy, safety and pharmacokinetics of a blonanserin transdermal patch in patients with acutely exacerbated schizophrenia.

    METHODS: This double-blind, multicenter, phase 3 study consisted of a 1-week observation period during which patients were treated with two patches of placebo, followed by a 6-week double-blind period where patients were randomized (1:1:1) to receive once-daily blonanserin 40 mg, blonanserin 80 mg, or placebo patches. The primary endpoint was the change from baseline in the total Positive and Negative Symptom Scale (PANSS) score. Safety assessments included treatment-emergent adverse events (TEAEs).

    RESULTS: Between December 2014 and October 2018, patients were recruited and randomly assigned to blonanserin 40 mg (n = 196), blonanserin 80 mg (n = 194), or placebo (n = 190); of these, 77.2% completed the study. Compared with placebo, blonanserin significantly improved PANSS total scores at 6 weeks (least square mean [LSM] difference vs placebo: -5.6 with blonanserin 40 mg; 95% confidence interval [CI] -9.6, -1.6; adjusted p = 0.007, and - 10.4 with blonanserin 80 mg; 95% CI -14.4, -6.4; adjusted p

    Majority people with schizophrenia who smoke cigarettes, tend to be heavy smokers than other psychiatric patients and general population. Nicotine is one of the main components of cigarettes that can produce nicotinic interactions with antipsychotic drugs. Nicotine can also alleviate psychotic symptoms of schizophrenia. Aim: The objective for this systematic review is to examine the effects of nicotine and nicotine-based products in the treatment of schizophrenia, in comparison with placebo, no treatment or antipsychotic medication. Results: All studies comparing nicotine or other related products as the only treatment or adjunctive treatment for schizophrenia patients excluding the animal studies and case studies are reviewed. The use of traditional or known as typical antipsychotics may cause the patients to smoke frequently while patients taking atypical antipsychotics may smoke less. Patients who smoke may metabolize antipsychotics faster than non-smoking patients. There is less report related to smoking cessation among the schizophrenia patients. Conclusion: Neurobiological and psychosocial factors reinforce the high use of nicotine by patients with schizophrenia. Prior to smoking cessation implementation, it is crucial to understand on the ways and reasons for schizophrenia patients to consume nicotine for self-medicate symptoms which may lead to the development of new treatments for schizophrenia and nicotine dependence.

    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.

    Aripiprazole (ARP) is one of antipsychotics and binds to human serum albumin (HSA) with a high affinity. In this study, we investigated the binding characteristics of ARP to oxidized HSA as observed in chronic disease conditions. Oxidized HSAs were prepared using chloramine-T (CT-HSA) or metal-catalyzed oxidation system (MCO-HSA) in vitro, respectively. An increase in the carbonyl content was confirmed in oxidized HSAs. From the results of circular dichroism (CD) and tryptophan fluorescence spectra, no significant structural change of oxidized HSAs was observed. These results indicate that prepared HSAs are mildly oxidized and well reflects the status of HSA during chronic diseases. However, oxidized HSAs were observed to have a significant decrease in binding to ARP. The results of the induced CD spectrum suggested that ARP bound to oxidized HSAs with a similar orientation. These results suggest that oxidation of HSA during chronic disease state significantly affected the microenvironment of the binding site for ARP and binding capacity of HSA to ARP.

    OBJECTIVE: The objective of this study was to assess the effectiveness and safety of olanzapine in the treatment of schizophrenia among Asian patients in an outpatient setting.

    METHODS: This was an open-label, prospective, observational study involving 339 patients from Indonesia, Pakistan, Malaysia, Thailand, and Singapore. Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression Severity scale (CGI-S), and safety parameters were assessed.

    RESULTS: 62% of patients responded to olanzapine treatment, defined a priori as a reduction in BPRS of > 40% from baseline. Following the 8-week treatment period, the BPRS total, BPRS positive, BPRS negative, and CGI-S scores decreased by 18.7 (95% CI: 17.4, 20.2), 6.1 (5.6, 6.6), 2.9 (2.6, 3.2), and 1.5 points (median 1.0), respectively (p < 0.0001). In total, 31 of the 339 patients (9.1%) failed to complete the study according to the study description. Loss to follow-up and personal conflict were the most common reasons for discontinuation. There were 30 treatment-emergent adverse events with six serious cases, assessed as unrelated to study drug, reported.

    CONCLUSION: This study further demonstrates the effectiveness and safety of olanzapine in actual clinical practice settings, in reducing the severity of psychopathological symptoms in Asian patients with schizophrenia.
