Munchausen syndrome by proxy (MSBP) is emerging as a serious form of child abuse. It is an intentional production of illness in another, usually children by mothers, to assume sick role by proxy. It is poorly understood and a controversial diagnosis. Treatment is very difficult. We present a case of 9-year-old boy brought to Pt. B. D. Sharma, PGIMS, Rohtak, a tertiary care hospital in northern India by his father and paternal uncle with complaints of hematemesis since July 2012. He underwent many invasive procedures until the diagnosis of MSBP was finally considered. The examination of the blood sample confirmed the diagnosis. The child was placed under custody of his mother. The case was reported to social services, which incorporated whole family in the management.

Background: Vitamin B12 deficiency is a common condition causing neurologic, cognitive, psychiatric, and mood symptoms. With varied religious, ethnic, and socioeconomic heterogeneity among the people in India greatly influencing their dietary habits and with the high prevalence of Helicobacter pylori infection, Vitamin B12 deficiency is not uncommon, but is often under recognized due to the lack of classical symptomatic presentation. Materials and Methods: Retrospective study on Vitamin B12 deficiency with neuropsychiatric symptoms in patients who attended neurology, psychiatry, and geriatric OPDs for a period of 1 year in a specialized neuropsychiatric institute in South India. Results: Out of 259 patients who had Vitamin B12 deficiency (<220 pmol/L), 60 had neuropsychiatric symptoms. Among them the Vitamin B12 levels were <150 (severe), 150-200 (moderate), and 201-220 pmol/L (mild) in 19, 24, 17 patients, respectively. Twenty one were diagnosed with Posterior dementias, 20 with frontotemporal dementia, 7 with Schizophrenia, 4 each with Parkinson's disease and alcohol-dependent syndromes (ADS), 3 with bipolar affective disorder, and 1 with Creutzfeldt-Jakob disease. Eight patients also had hypothyroidism. First symptom of presentation was behavioral disturbances in 30 (50%), memory loss in 20 (33.9%), and sensorimotor and movement disorders in 9 (15.3%), and 56.7% were vegetarians while 43.3% were nonvegetarians. In our study, Vitamin B12 deficiency was more prevalent in elderly males (56.67%) and was associated with increased severity of behavioral disturbances (P = 0.043) which was the most common presentation. Memory loss was present in 16 (84.2%) patients of severe Vitamin B12 deficiency. Hindi mental status examination (HMSE) score was graded as <20, 20-24, 24-31 in 37 (61.7%), 10 (16.7%), and 13 (21.7%) patients, respectively. Cognitive decline in Vitamin B12 deficiency was significantly associated with increased serum cholesterol (P = 0.019) and was significantly prevalent in neurological disorders when compared with primary psychiatric illnesses (P = 0.001). Mean folate and mean homocysteine in our study was 11.7 ± 6.44 ng/ml and 17.77 ± 5.45 μmol/L, respectively. Eighty percent of the population had normal folate levels whereas mean homocysteine values were much higher than that of the western population (10-12 μmol/L). Conclusion: Vitamin B12 deficiency though common in India is often overlooked. It increases the load of cognitive decline and accentuates vascular risk factors in neuropsychiatric illnesses. Vitamin B12 deficiency also increases homocysteine levels contributing to the vascular comorbidity in cerebro and cardiovascular illnesses. So prevention, early detection, and management of this reversible Vitamin B12 deficiency state is of profound importance.

Context: Cognitive behavior therapy (CBT) is the treatment of choice in anxiety disorders. However, there is little evidence for the effectiveness brief CBT in social anxiety. Aims: We examined the effectiveness of a brief CBT of six sessions in patients with social anxiety disorder. Settings and Design: A single case design study baseline; post and 1 month follow-up was adopted. Materials and Methods: Seven patients with a DSM IV diagnosis of social anxiety underwent 6 weekly sessions of brief CBT. Their diagnosis was confirmed using structured diagnostic interviews. They were assessed at baseline, post and 1-month follow-up on CGI- Severity, Leibowitz Social Anxiety Scale (LSAS), Social Phobia Rating Scale, Brief Fear of Negative Evaluation, and Beck's Depression Inventory. Statistical Analysis: Data were analyzed using the method of clinical significance. Results: Results indicated that brief CBT was effective in reducing social anxiety in all patients. Brief CBT was also effective in reducing social avoidance and self consciousness. However, brief CBT was not effective in reducing fear of negative evaluation in all patients, suggesting the need for longer duration for cognitive changes in some dysfunctional beliefs. Conclusions: This preliminary case series indicates that brief CBT may be a promising and a cost and time effective approach to managing for social anxiety.

Background: Apraxia is a state of inability to carry out a learned motor act in the absence of motor, sensory or cerebellar defect on command processed through the Praxis circuit. Breakdown in default networking is one of the early dysfunction in cortical dementias and result in perplexity, awkwardness, omission, substitution errors, toying behavior and unrecognizable gestures in response to command with voluntary reflex dissociation where, when unobserved patient will carry out reflex movements normally. Awareness into the organicity of these phenomenas will help in early diagnosis, which will help in initiating appropriate treatment and slowing down the progression of the disease. Aims and Objectives: The aim was to look for the various kinds of apraxias in patients with dementia using appropriate simple tests. Patients and Methods: Three hundred patients satisfying Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for dementia were evaluated in detail with mandatory investigations for dementia followed by testing for ideational, ideomotor, limb-kinetic, buccopharyngeal, dressing apraxia, constructional apraxia and gait apraxias in addition to recording of rare apraxias when present. Results: Alzheimer's disease showed maximum association with apraxias in all the phases of the disease ideational, ideomotor, dressing and constructional apraxias early and buccopharyngeal and gait apraxia late. Frontotemporal lobe dementia showed buccopharyngeal and gait apraxias late into the disease. Cortical basal ganglionic degeneration showed limb apraxias and diffuse Lewy body disease showed more agnosias and less apraxias common apraxias seen was Ideational and Ideomotor. Conclusion: Recognition of the apraxias help in establishing organicity, categorization, caregiver education, early strategies for treatment, avoiding anti-psychotics and introducing disease modifying pharmacotherapeutic agents and also prognosticating.

Impairment of insight is considered as the hallmark of schizophrenia. Substantial proportion of patients with schizophrenia has either poor or absent insight. Insight is a multidimensional and dynamic construct which appears to have intricate links with other symptom dimensions of the psychotic illness. A better appreciation of the association that insight shares with other symptom clusters in psychosis could help us in gaining knowledge about aetiology, prognosis and treatment-related facets of the disorder. This is likely to have critical implications in the understanding and therapeutics of schizophrenia.

Objective: The objective of this study was to evaluate the socio-demographic and the clinical profile of children and adolescents presenting with Intentional self-harm. Materials and Methods: Records of all children and adolescents (≤19 years) seen by the consultation liaison (CL) services during the period of 2000-2012 were screened. Patients with a diagnosis of intentional self-harm (at the time of assessment) were taken up for this study. Data was extracted from the records, to study the socio-demographic and clinical profile. Results: During the study period, 101 patients aged ≤19 years and diagnosed with intentional self-harm at the time of admission were evaluated by the psychiatry CL services in various emergency and medical surgical wards. In the study population, females (N = 61; 60.4%) outnumbered males. The age of the patients ranged from 12 to 19 with a median and mean of 17.0 years (standard deviation-1.6 years; interquartile range 16-18 years). Children and adolescent with self harm were more commonly females, from nuclear families, middle socio-economic status and Hindu by religion. The common method of self-harm in adolescents is by ingestion of insecticides (65%) and the self-harm behavior was often precipitated by interpersonal problems in the family context. About one-fifth of the patients have psychiatric morbidity. Conclusion: Findings suggest that the most common method of intentional self-harm in children and adolescents is consumption of insecticides and precipitated by interpersonal problems in the family context.

Background: Polycystic ovary syndrome (PCOS) is one of the common endocrine disorders and is associated with reproductive, metabolic, and psychological disturbances affecting one in five women of reproductive age group. Objective: To investigate the prevalence of psychiatric disorders among women in ambulatory treatment with a diagnosis of PCOS. Materials and Methods: One hundred and ten patients of PCOS were evaluated using Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition criteria by means of Mini International Neuropsychiatric Interview, English version 5.0.0. Diagnosis of PCOS was confirmed according to the National Institute of Health/National Institute of Child Health and Human Development, 1990 consensus conference criteria. Forty subjects without PCOS who were matched for age and body mass index were taken as a comparison group. Results: About 23% of cases had major depressive disorder as compared to 7.5% of controls, 1.8% had dysthymia, 15.45% had panic disorder compared to 5% of controls, 6.36% had obsessive compulsive disorder compared to 2.5% of controls, 8% cases had suicidality, 2.72% of cases were bipolar affective disorder, and 15.45% had generalized anxiety disorder (GAD). Conclusion: A high prevalence of mental disorders was observed, especially major depression, panic disorder, and GAD in patients with PCOS in our study. The results suggest that screening and appropriate management for psychiatric disorders should be part of the routine evaluation of these patients.

Masturbation is common in all societies. Despite being common, it is admonished culturally and almost all religions prohibit masturbation and consider it an act of immorality. The prohibition for masturbation leads to a lot of cultural beliefs, including certain myths, which influence sexual behavior of the person. The impact of these common cultural myths associated with masturbation, are clinically understood as Dhat syndrome and masturbatory guilt. Although there is a reasonable literature on Dhat syndrome, there is limited literature with regard to masturbatory guilt especially linking the same with axis-I psychopathology. In this case series, three cases of masturbatory guilt are presented in whom masturbatory guilt was associated with manifestation of severe psychopathology. This report suggests that masturbatory guilt must be enquired for in patients presenting with severe mental disorder.

Background: Intelligence quotient (IQ) but not the core symptoms have been known to predict outcomes in autism. Besides resource issues in India, assessing IQ in presence of autistic symptoms is challenging in general. Materials and Methods: In a pilot study, we explored different global indices of development in 30 children with confirmed autism. These included Wechsler intelligence scale for children or Wechsler preprimary scale of intelligence-revised (n = 10), Raven's progressive matrices (RPM) (n = 10), Vineland adaptive behavior scales II, parent report version (VABS) (n = 30) and teacher's estimate of mental age (TIQ) (n = 30). Three subgroups (Group A) with Wechsler's scales derived IQ (WISIQ), (Group B) with RPM derived IQ and (Group C) those without a formal IQ measure were compared. Results: All groups were comparable on age and their scores on Childhood Autism Rating Scale and Indian Scale for Assessment of Autism Adaptive behavior composite scores (Ad Bh composite) derived from VABS and WISIQ showed significant correlations with each other in Group A; TIQ significantly correlated with Ad Bh composite scores, but not with the WISIQ, although the latter two scores themselves did not significantly differ from each other. RPM consistently overestimated children's performance compared to Ad Bh composite or TIQ in Group B, but the Ad Bh composite and TIQ were themselves significantly correlated. In Group C, there were poor correlations between Ad Bh composite and TIQ. The Ad Bh composite score in this group was significantly different from the other two groups. Conclusion: There is a need to fine tune the assessment for global cognitive measures in autism and explore their real world importance.

Background: Suicide is an act of intentionally causing one's own death. Number of suicidal incidences is proportional to attempted suicide cases hence if attempt cases are reduced, number of suicidal death can also be decreased and for that purpose risk factors should be identified and reduced. Therefore, this study is planned to identify risk factors among lower socioeconomic rural population of surrounding areas of Hyderabad in India. Materials and Methods: This was a prospective study in which all the suicide attempt cases reported at Bhaskar Medical College and General Hospital were included. The study period was from January 2013 to July 2013. They were undergone a detailed psychiatric interview, including their demographic details, and complete suicide risk assessment was done using Beck's suicide intent scale. Results: It was found that females in the age group of 20-30 years, uneducated, married and daily laborers by occupation had higher incidence of suicidal attempts. Depressive disorder is the most common associated psychiatric disorder in both the genders, followed by alcohol use related problems. Family disputes are the other major risk factors. Most common mode for attempt was organophosphorous poisoning followed by ingestion of calotropis. Conclusion: Risk of suicide attempt is almost equal in terms of medium and high category of suicide assessment scale in both genders. We suggest that all individuals with alcohol related disorders must be screened for suicidal ideation so that appropriate methods can be adopted to reduce the risk.

A 46-years-old male, with past history of road traffic accident and with no current/past history of substance abuse and no family history of sleep-walking, took zolpidem 10 mg without any prescription and after few days, the patient's son noticed the patient waking up in the middle of night and walking into their room with a staring expression and some incoherent speech. The patient had no memory of this event in the morning. This sleep-walking episode was attributed to zolpidem, as no medication change was made besides new start of zolpidem and the patient had no history of such episodes in the past. Zolpidem treatment was stopped, and since then, no further complaints of sleep-walking were reported.

Background: Early Life Stress (ELS) can profoundly influence an individual's genotype and phenotype. Effects of ELS can manifest in the short-term, late life and even in subsequent generations. ELS activate corticotrophin releasing factor (CRF); CRF influences drug seeking and addiction. The aim of this study was to examine the effects of endogenous elevated levels of CRF on addiction. Materials and Methods: Inducible forebrain over-expression of CRF mice (tetop-CRH x CaMKII-tTA) was used for this study. Morphine (10 mg/kg) was administered every other day for 10 days or with increasing doses of morphine: 20, 40, 60, 80, 100, and 100 mg/kg. The behavioral trials including morphine sensitization, Somatic Opiate Withdrawal Symptoms (SOWS) were conducted in a single, open field, activity. After behavioral trial, animals were perfused for immunohistochemistry analysis. Results: CRF-over expressed (CRF-OE) mice showed increase in morphine sensitization and withdrawal symptoms after morphine administration compared to wild type (WT) mice. The two-way ANOVA in the morphine sensitization study showed a significant effect of treatment (P<0.05) and genotype for distance traveled (P<0.01). In the SOWS study, opiate withdrawal symptoms such as rearings, circling behavior, grooming, and jump in CRF-OE were amplified in parallel to WT mice. In the immunohistochemistry study, pro-dynorphine (PDYN) expression was increased after morphine administration in both amygdala and nucleus accumbens (NAcc). Conclusions: CRF-OE in the forebrain increases the sensitization and withdrawal symptoms in morphine treated mice. On exposure to morphine, in CRF-OE mice the PDYN protein expression was increased as compared to WT mice in the amygdala and NAcc.

Background: Ego-boundary disturbance (EBD) is a unique symptom cluster characterized by passivity experiences (involving thoughts, actions, emotions and sensations) attributed by patients to some external agency. The neurobiology of these "first rank" symptoms is poorly understood. Aberrant mirror neuron activation may explain impaired self-monitoring and agency attribution underlying these symptoms. We aim to study mirror neuron activity (MNA) in schizophrenia patients with and without EBD using transcranial magnetic stimulation (TMS). Materials and Methods: 50 right-handed schizophrenia patients (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) were evaluated using the Mini-International Neuropsychiatric Interview and the Positive and Negative Syndrome Scale. They completed a TMS experiment to assess putative premotor MNA. Motor evoked potential (MEP) was recorded in the right first dorsal interosseous muscle (FDI) with (a) 120% of resting motor threshold (RMT), (b) stimulus intensity set to evoke MEP of motor threshold 1 mV amplitude (MT1), (c) two paired pulse paradigms (short- and long interval intra-cortical inhibition). These were done in three states: Actual observation of an action using the FDI, virtual-observation (video) of this action and resting state. The percent change of MEP from resting to action-observation states formed the measure of putative MNA. Results: MNA measured using MT1 and 120% RMT paradigms was significantly lower in the 18 patients with EBD (thought-broadcast/withdrawal/insertion, made-act/impulse/affect and somatic passivity) than the 32 patients without EBD (t = 2.431, P = 0.020; t = 2.051, P = 0.04 respectively for the two paradigms). The two groups did not differ on age, gender, education and total symptom scores. Conclusion: Schizophrenia patients with EBD have lower premotor MNA. This highlights the role of MNA dysfunction in the pathophysiology of this unique and intriguing symptom cluster in schizophrenia.

Antidepressants have propensity to induce manic switch in patients with bipolar disorder. Opipramol is an atypical anxiolytic and antidepressant drug which predominantly acts on sigma receptors. Although structurally resembles tricyclic antidepressant imipramine it does not have inhibitory action on the reuptake of norepinephrine/serotonin and hence it is not presumed to cause manic switch in bipolar depression. Here, we describe a case of mania induced by opipramol, in a patient with bipolar affective disorder who was treated for moderate depressive episode with lithium and opipramol and we discuss neurochemical hypothesis of opipramol-induced mania.

Background: Scale for assessment of somatic symptoms (SASS) has been widely used for assessing somatic complaints since many years. With impending changes in the classificatory system on somatoform disorders, we re- assessed the test-retest reliability and inter-rater reliability of SASS. Materials and Methods: SASS was administered twice with a gap of 24 h on 20 subjects for test retest reliability. Two clinicians assessed inter-rater reliability on 20 subjects. Kendall tau B and Cronbach's alpha were calculated from the data. Results: All of the items except burning sensation, weakness of mind and trembling had strong correlation with values >±0.40 on both test retest and inter-rater reliability; burning sensation and trembling were not reported by any subject. On inter-rater reliability the items constipation, diarrhea, lack of libido weren't scored by any subjects. Cronbach's alpha for test retest was 0.982 and 0.840 indicating good internal consistency. Conclusion: Majority of the symptoms in SASS had high correlation in both test retest reliability as well as inter-rater reliability, however few items needs revision.

Background: Combination of ill health and poverty poses special challenges to health care providers. Mental illness and costs are linked in terms of long-term treatment and lost productivity, and it affects social development. The purpose of the present study is to assess the economic burden of poor families when a family member needs hospitalization due to psychosis. Materials and Methods: The information was gathered from caregivers of 100 psychotic inpatients of Medical College Hospital of Kerala during a period of 6 months. Data regarding components of expenses such as cost of medicine, laboratory investigations, food, travel, and other miscellaneous expenses during their inpatient period were collected by direct personal interview using specially designed proforma. The data were analyzed using Epi-info software. The patients below the poverty line (BPL) were compared with those above poverty line (APL). Results: There was no significant difference between patients from BPL and APL in respect of amounts spent on the studied variables except for laboratory investigations during the hospital stay. Conclusions: The results showed that the studied subjects are facing financial difficulties not only due to hospitalization, but also due to the recurrent expense of their ongoing medication. The study recommends the need of financial support from the government for the treatment of psychotic patients.

Background: Primary care has been identified as a key setting for the reduction of alcohol-related harm, while general practitioners are expected to play a significant role. The study aimed at identifying pattern of, and factors that are associated with alcohol use disorders (AUDs) among patients attending Family Medicine unit of State University Teaching Hospital. Materials and Methods: Sample was selected through a random sampling from a population of patients, aged 18-65 years, attending the general medical out-patients unit of the hospital from January to April 2013. A pretested, semi-structured questionnaire was administered, incorporating sociodemographics and the diagnoses made by the attending Physician. The participants also completed the alcohol use disorders identification test (AUDIT) questionnaire and the patient health questionnaire-9. Results: The prevalence of AUDs among the population of general out-patients was 9.7%. The AUDIT scores of the participants range from 0 to 29 with a mean of 1.3 (standard deviation = 4.08). AUDs were significantly associated with gender, level of education, occupational class, and the presence of significant depressive symptoms (P < 0.05). There was no statistically significant association found for age, employment status, marital status, and religion. Conclusion: The prevalence of AUDs among population studied was lower compared with a similar study in similar setting, but however, significant. AUDs were predicted by gender, lower education level, occupational group, and the presence of significant depressive symptoms mostly in the mild to moderate form. Identifying the group at risk in clinical setting may go a long way in reducing the adverse effect of AUDs in our society.
