RESUMO
Background & objectives: Comprehension and process of consent are important for persons with mental illness as they may not be impaired in considering research participation. The American Psychiatric Association developed a detailed Cultural Formulation Interview (CFI). The present study was a part of field testing of CFI, aimed to standardize cultural information affecting the patients' management in India. This paper describes the process and conclusions from the consent-seeking process of this study. Methods: The purpose and procedures about field trial of the CFI were introduced and the patient and caregiver were requested for participation. Consent process was carried out step by step, by reading out the consent form to the first new patient of the day in the psychiatry outpatients department of a tertiary care hospital in north India, inviting questions followed by the 'comprehension' questions. The entire process was audiotaped without any personal identifiers. The process was repeated if not comprehended. Results: A total of 67 patients consented, 11 refused and majority were educated more than secondary school. Some concerns shown by the patients and caregivers included risk of participation, loss or benefits of participation, privacy, etc. All types of mentally ill patients participated in the study. Interpretation & conclusions: Translations of consent forms used simple words, consonant with understanding of the potential participants. Patients' belief that participating in this long process would improve their care, and serve humanity, influenced their decision to participate. Except for intoxication and severe psychosis, patients could understand and comprehend issues around consent. Main issues were confidentiality and culture. Our experience in the psychiatry OPD refutes the commonly held belief that mentally ill persons lack comprehension and ability to consent.

Hyponatremia is a rare, yet potentially life threatening complication of antipsychotics. Here, we report a case of a 45-year-old female diagnosed with schizophrenia who developed hyponatremia soon after addition of olanzapine to the existing treatment. This prompted us to evaluate the relationship between hyponatremia and olanzapine, as timely management is crucial. Naranjo algorithm established a "probable" causal relation between olanzapine and hyponatremia. Possible etiological reasons of this clinically significant and life threatening adverse event have been discussed. We report the case and the literature focusing on hyponatremia as a possible adverse event of olanzapine. Medical illnesses are often ignored or missed in patients with psychiatric disorders either due to patients' inability to report complaints or non-serious attitude of physicians towards such patients. A high index of suspicion should be kept while dealing with this probable complication.
RESUMO
CONTEXT: Alcohol consumption has escalated rapidly in many countries over the past decade. Evidence suggests a correlation between alcohol use and cognitive decline. We have systematically reviewed the concept and controversies, epidemiology, nosology, neuropathology and neurobiology, neuropsychology and management updates of alcohol-related dementia (ARD) in this paper. EVIDENCE ACQUISITION: We retrieved papers for this review by searching the PubMed database for terms "alcohol and dementia", "alcohol and cognitive impairment", and "alcohol and wernicke-korsakoff" mentioned in the title of the published papers. A total of 131 studies showed up. Appropriate studies were shortlisted and included (n = 72). Cross-references if relevant were considered from the selected studies. Eligible articles were fully read by the authors and the results were compiled. RESULTS: The prolonged and excessive use of alcohol may lead to structural and functional brain damage, leading to ARD. The cognitive deficits are most frequently observed in domains of visuospatial functions, memory and executive tasks, with a potential of partial recovery if abstinence is maintained. However, there are doubts regarding the etiopathogenesis, nosological status, prevalence and diagnostic criteria for ARD, due to difficulty in assessment and various confounding factors. CONCLUSIONS: With growing cohort of young and middle-aged people, there is a probable risk of upsurge of ARD. Presently, there are dilemmas over the diagnosis of independent ARD. Thus, there is a need to develop evidence-based guidelines for diagnosis and management of ARD through further systematic studies.
RESUMO
Alcohol dependence is an increasing and pervasive problem. Alcohol withdrawal symptoms are a part of alcohol dependence syndrome and are commonly encountered in general hospital settings, in most of the departments. Alcohol withdrawal syndrome ranges from mild to severe. The severe complicated alcohol withdrawal may present with hallucinations, seizures or delirium tremens. Benzodiazepines have the largest and the best evidence base in the treatment of alcohol withdrawal, and are considered the gold standard. Others, such as anticonvulsants, barbiturates, adrenergic drugs, and GABA agonists have been tried and have evidence. Supportive care and use of vitamins is essential in the management. Symptom triggered regime is favoured over fixed tapering dose regime, although monitoring through scales is cumbersome. This article aims to review the evidence base for appropriate clinical management of the alcohol withdrawal syndrome. We searched Pubmed for articles published in English on 'Alcohol withdrawal syndrome' in humans during the last 10 years. A total of 1182 articles came up. Articles not relevant to clinical utility and management were excluded based on the titles and abstract available. Full text articles, meta-analyses, systematic reviews and randomized controlled trials were obtained from this list and were considered for review.
RESUMO
BACKGROUND: Schizophrenia cases have been consistently shown to have behavioural and neurofunctional abnormalities but studies during early course are scarce. The present work assesses the performance of acute first episode schizophrenia cases on correlation of a facial emotion perception task with brain function using fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET). METHODS: Twenty First episode schizophrenia cases and 20 matched healthy controls living in the community were enrolled. For cases, longest duration of illness was one year and treatment with neuroleptic did not exceed two weeks on the day of scan. To measure facial emotion perception (FEP) both groups were administered the Emotion battery from the Penn Computerized Battery followed by PET acquisition. SPM 8 analysis for group differences at p<0.001 was performed. RESULTS: Schizophrenia subjects showed hypoactivation of bilateral prefrontal cortices and fusiform gyrii, with significant hyperactivation of bilateral basal ganglia and left precuneus. Positive correlation of metabolism in prefrontal cortex and performance indices on emotions domain was seen. No correlation of chlorpromazine equivalent days with metabolism in basal ganglia was observed. CONCLUSIONS: The performance of schizophrenia cases on FEP task was significantly impaired in comparison to the control group. Brain regions implicated in emotion processing showed hypometabolism in cases as compared to controls. Failure of schizophrenia cases to optimally recruit brain circuitry may be contributing to deficits on FEP task. These findings suggest inherent deficits in neural circuitry of emotion processing in schizophrenia; devoid of confounding effects of neuroleptics and duration of illness.

Although malaria is one of the oldest types of parasitic infection, we have recently witnessed substantial changes in the outcome of malarial infections. Severe Plasmodium vivax infections have recently become more frequent, and are occasionally associated with fatal outcomes. Cardiac arrhythmia and myocardial failure have also been reported, typically in association with Plasmodium falciparum infections. We report a case of myocarditis and heart failure, due to Plasmodium vivax infection, along with the favorable outcome.
