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.

BMJ Case Rep, 2017 Aug 28;2017.

PMID: 28847993 DOI: 10.1136/bcr-2017-220631

A patient with bipolar I disorder has been treated with lithium and haloperidol for the last 20 years and received an ACE inhibitor for his hypertension since 9 years ago. Despite regular clinic follow-ups and blood monitoring, he recently developed tremors and delirium. On hospital admission, serum level of lithium was far above toxic level. Mental state examination revealed an anxious and disorientated man with irrelevant speech. Immediate discontinuation of lithium resulted in slow reduction of serum lithium levels and gradual resolution of tremor but his delirium persisted for 2 weeks. His condition took a turn for the worse when he developed acute renal failure and arm abscess. We discussed about lithium toxicity and the vulnerability factors which have induced delirium and renal failure in this patient.

Paraphilia without symptoms of primary psychiatric disorder: a case report

Pang NTP, Masiran R, Alimuddin AS

J Med Case Rep, 2023 Feb 13;17(1):46.

PMID: 36775819 DOI: 10.1186/s13256-023-03774-8

BACKGROUND: Paraphilias are recurrent and arousing fantasies, thoughts, and behaviors that cause distress to sufferers and surrounding people. This case report details the challenge of managing multiple paraphilias with compulsive sexual behavior.

CASE PRESENTATION: A 48-year-old Malay man presented with compulsive sexual behavior, encompassing voyeuristic, frotteurism, and exhibitionistic behavior, increasing progressively over the years, with accompanying overvalued ideas of erotomania. Despite the high level of dysfunction occupationally and socially, there were no apparent psychotic, manic, or depressive symptoms. An organic workup was unremarkable, and he was diagnosed with multiple paraphilias. Treatment with selective serotonin reuptake inhibitors was commenced, and psychologically he was managed with techniques specific to compulsive sexual behavior.

CONCLUSION: Though rare in the literature, both paraphilic disorders and compulsive sexual behaviors are very distressing to sufferers and their families alike, and thorough biopsychological investigations are essential to ensure reversible causes are not overlooked.

Methylphenidate-associated chest pain in a child

A young child was diagnosed with autism spectrum disorder with comorbid attention-deficit/hyperactivity disorder. His hyperactivity, impulsivity and absence of awareness towards danger increased his risk of harm and hence methylphenidate was indicated. Unfortunately, he developed chest pain eight months after the treatment initiation. We then stopped the stimulant and changed his treatment to atomoxetine, after which he no longer had chest pain. In the following illustrated case, we will discuss the cardiac side effect of methylphenidate.

Psychological mindedness as a mediator in the relationship between dysfunctional coping styles and depressive symptoms in caregivers of children with autism spectrum disorder

Ping Pang NT, Masiran R, Tan KA, Kassim A

Perspect Psychiatr Care, 2020 Jul;56(3):649-656.

PMID: 32017137 DOI: 10.1111/ppc.12481

PURPOSE: Psychological mindedness (PM) can partly explain depressive symptoms in caregivers of autism spectrum disorder (ASD). This cross-sectional study examines PM in mediating the relationship between dysfunctional coping styles and depressive symptoms.

DESIGN AND METHODS: One hundred fifty-five adult ASD caregivers completed the Malay version of Brief COPE, the Patient Health Questionnaire-9, and the Balanced Index of PM.

FINDINGS: Direct paths between dysfunctional coping style and depressive symptoms, between insight and depressive symptoms, and between dysfunctional coping style and all PM variables (insight and interest) were obtained. Multiple regression analyses revealed that insight, but not interest, significantly mediates the relationship between dysfunctional coping and depressive symptoms.

PRACTICAL IMPLICATIONS: PM can be enhanced via psychological interventions.

Improving multicultural parenting program for children with emotional and behavioral problems: An integrated review

Masiran R, Ibrahim N, Awang H, Lim PY

Asian J Psychiatr, 2020 Jun;51:101851.

PMID: 31711780 DOI: 10.1016/j.ajp.2019.101851

Children with emotional and behavioral problems are often managed using medications or behavioral therapy, but in some countries, there is no structured parenting intervention to equip parents from different cultural backgrounds with adequate parenting skills to help these children. This paper aims to synthesize key findings from previous research on multicultural parenting programs and produce a comprehensive integrated view by looking into three separate themes: effective multicultural parenting programs, ethnocultural groups and cultural adaptation process. Literature search through Scopus and Google Scholar from 1999 to 2019 was conducted using the terms "effective parenting program", "effective parenting intervention", "effective multicultural parenting program", "effective multicultural parenting intervention", "multicultural parenting program", "multicultural parenting intervention", "parenting program and ethnic groups", "parenting intervention and ethnic groups", "adapted parenting program", "adapted parenting intervention", "cultural adaptation of parenting program'' and "cultural adaptation of parenting intervention". By applying the "Literature Review Synthesis Process", authors conducted cross-analysis, integrated possibilities, and prioritized the synthesized information gearing towards highly probable solutions for improving multicultural parenting programs to manage emotional and behavioral problems in children better. Development of a culturally fit parenting intervention and its implications on existing parenting programs are also discussed. The findings highlight the need 1) to engage with ethnocultural groups of parents during development of a new multicultural parenting program, and 2) to incorporate specific measures for engaging with parents during multicultural parenting program implementation. This paper contributes in acknowledging cultural components in future parenting intervention programs. Finally, recommendations are made for future directions of research.

Fulltext Directly observed therapy for clozapine with concomitant methadone prescription: a method for improving adherence and outcome

Pang NTP, Mohamad Isa MF, Suarn Singh V, Masiran R

BMJ Case Rep, 2017 Jul 27;2017.

PMID: 28754761 DOI: 10.1136/bcr-2017-221048

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.

Bilateral Motor Cortex Control for Left Thumb Movement: An Incidental Finding Through Functional MRI (fMRI)

BMJ Case Rep, 2018 Jan 04;2018.

PMID: 29301796 DOI: 10.1136/bcr-2017-221129

We report a case of a healthy, right-hand dominant young male who was a volunteer for a pilot run of a functional MRI (fMRI) study. The fMRI was performed with a 3.0 Tesla MRI scanner using a finger tapping task-based activity. The subjects were instructed to perform flexion of the right thumb and left thumb consecutively (activation task) and neuronal activation in bilateral primary motor cortex (PMC) were observed during each task. One particular subject demonstrated bilateral PMC activation during the left-thumb movement task, instead of the expected activation of the contralateral PMC alone.

Association between 5HT2A polymorphism and selective serotonin re-uptake inhibitor (SSRI)-induced sexual desire disorder (SDD) among Malaysian women

Asia Pac Psychiatry, 2013 Apr;5 Suppl 1:41-9.

PMID: 23857836 DOI: 10.1111/appy.12043

SSRIs are known for their sexual side-effects with a variable rate of sexual dysfunction (SD). 5HT2A (rs6311) single nucleotide polymorphism (SNP) was found to have significant association with SD. The purpose of this study was to determine the prevalence of female SDD, its clinical correlates and association with 5HT2A (rs6311) SNP in patients with major depressive disorder (MDD) treated with SSRIs.

Serotonin Selective Reuptake Inhibitors (SSRIs) and Female Sexual Dysfunction (FSD): Hypothesis on its Association and Options of Treatment

Rappek NAM, Sidi H, Kumar J, Kamarazaman S, Das S, Masiran R, et al.

Curr Drug Targets, 2018;19(12):1352-1358.

PMID: 28025939 DOI: 10.2174/1389450117666161227142947

Sexual dysfunctions are commonly seen in women on selective serotonin reuptake inhibitors (SSRIs). The complexities of female sexual functioning are reflected through modulation of inter- playing factors like the neuropsychophysiological factors, inter-personal and relationship issue, psychiatric co-morbidities and physical disorder. The incidence of SSRIs-induced FSD is difficult to estimate because of the potential confounding effects of SSRIs, presence of polypharmacy, marital effect, socio-cultural factors and due to the design and assessment problems in majority of the studies. The exact mechanism of FSD-induced SSRIs is unknown. It has been postulated that although SSRIs may modulate other neurotransmitter system such as nitric oxide (NO), noradrenergic and dopamine in inducing FSD. In the present review, we highlight current evidence regarding potential mechanism of SSRIs in causing FSD, which include low sexual desire (low libido), arousal difficulties (lack of lubrication), and anorgasmia. The specific association of FSD to SSRI use, has not been ellucidated. The relationship is dose-dependent, and may vary among the groups with respect to mechanism of serotonin and dopamine reuptake, induction of release of prolactin from the pituitary gland, anticholinergic side-effects, inhibition of NO synthesis and emotional-memory circuit encryption for sexual experiences. Various interventional strategies exist regarding the treatment of SSRI-induced FSD and this includes tolerance, titration dosage, substitution to another antidepressant drug and psychotherapy. There is a need of better understanding of SSRIs-induced FSD for better treatment outcome.

Hypersexuality As a Neuropsychiatric Disorder: The Neurobiology and Treatment Options

Asiff M, Sidi H, Masiran R, Kumar J, Das S, Hatta NH, et al.

Curr Drug Targets, 2018;19(12):1391-1401.

PMID: 28325146 DOI: 10.2174/1389450118666170321144931

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.

Phthalates exposure and attention-deficit/hyperactivity disorder in children: a systematic review of epidemiological literature

Praveena SM, Munisvaradass R, Masiran R, Rajendran RK, Lin CC, Kumar S

Environ Sci Pollut Res Int, 2020 Dec;27(36):44757-44770.

PMID: 32895790 DOI: 10.1007/s11356-020-10652-z

Epidemiological studies have proven that children mental health can be affected by environmental pollutants which are believed to be visible in the form of psychological disorder later in their childhood. Moreover, the effects of children mental health are evidently clear in the case of phthalates which have been observed to increase psychological disorder, specifically attention-deficit hyperactivity disorder (ADHD). Hence, the present study aims to conduct a systematic review and provide an overview of the existing literature on the association between urinary phthalate metabolite concentrations and ADHD symptoms among children by emphasizing the confounding factors and limitations. Additionally, this review addressed the possible phthalate mechanism insights in human body including its impact on ADHD symptoms. In this case, 16 epidemiological studies (five cross-sectional, nine cohort and two case control studies) that met all the inclusion criteria were selected out of the total of 427 papers screened to show varying quantitative associations between phthalate exposure and ADHD symptoms among children with confounding factors and limitations in the existing studies in regard to the exposure and outcomes. This review also attempted to present possible explanation on phthalate mechanism in children body and its connection on neurodevelopment and ADHD symptom development which remains unclear in most of the studies. Finally, it is highly recommended for further research to carefully design cohort studies from prenatal to later childhood development with a complete sample size in order to understand phthalate impacts on children health.
