July-December 2009, 18(2):119-126
DOI:10.4103/0972-6748.62273  PMID:21180490
The literature on hallucinations is reviewed, including history; theoretical background from physiological, biochemical and psychological points of view; classification; causation; presentation in different psychiatric and neurological disorders and in normal persons. The available evidence suggests that hallucinations result from a failure of the metacognitive skills involved in discriminating between self-generated and external sources of information. Management of hallucinations is briefly discussed.

Students' perception about mental illness
RK Mahto, PK Verma, AN Verma, AR Singh, S Chaudhury, K Shantna
July-December 2009, 18(2):92-96
DOI:10.4103/0972-6748.62267  PMID:21180484
Background: In developing countries like India, there are evidences that stigma associated with mental illness is increasing. As in parts of the developing world, with advancement of urbanization and rapid industrialization, people tend to react in a very peculiar and biased way when they confront a mentally ill person. Materials and Methods: The present study aimed to find out students' opinion about mental illness. A total of 100 students (50 male and 50 female) from Ranchi University were purposively recruited for the study, and the 51-item Opinion about Mental Illness (OMI) Scale was administered. Results: Majority of the students were from Hindu families, of whom 42 (84%) were males and 38 (68%) were females. With regard to OMI scale, the item, viz., 'The law should allow a woman to divorce her husband as soon as he has been confined in mental hospital with a severe mental illness', both male (46%) and female (56%) students were neutral (significant at 0.014, P < 0.05). Conclusion: Overall no significant level of difference emerged between male and female students with regard to opinion about mental illness.

Innovative work behavior of managers: Implications regarding stressful challenges of modernized public- and private-sector organizations
Sudeshna Basu Mukherjee, Anjali Ray
July-December 2009, 18(2):101-107
DOI:10.4103/0972-6748.62269  PMID:21180486
Background: The present study was firstly aimed to find out the nature of stressful life events arising out of the innovative challenges in modernized organizations; and secondly, it tried to identify the relationship between innovative work behavior of managers and the levels of stress arising out of stressful events in modernized organizations (public and private) in West Bengal. Materials and Methods: Data was collected from a sample of 200 managers, by using 3 tools (General Information Schedule, Life Event Inventory and Innovative Work Behavior Scale) through a face-to-face interview. Responses were subjected to both quantitative and qualitative analyses. The data was statistically treated for 't' and ANOVA. Results: Data highlighted the fact that the qualitative profile of stressful events in the lives of managers expressed specificity in terms of their organizational type (public- and private-sector modernized organizations), and levels of stress from stressful life events were significantly higher among the modernized private-sector managers than those among public-sector managers. The prevalence of innovative work behavior was moderately higher among managers of private-sector modernized organizations than their counterparts in public-sector organizations. The trends of innovative work behavior of the managers indicated much variability due to interaction of their level of perceived stressful challenges for innovation and the global forces of change that have unleashed dynamic, systematic and higher expectation level from them.

Intracranial (structural) changes in obsessive- compulsive disorder: A computerized tomography scan study
Deepak Kumar Giri, Indira Sharma
July-December 2009, 18(2):88-91
DOI:10.4103/0972-6748.62266  PMID:21180483
Objective: To assess intracranial structural changes in obsessive-compulsive disorder (OCD) with CT scan. Materials and Methods: Thirty patients of OCD between 21 and 40 years of age and fulfilling various inclusion and exclusion criteria were compared with control group. CT scans of all the patients and controls were taken and compared with regard to ventricular size, Evan's ratio and ventricular brain ratio (VBR). Results: Patients of OCD were found to have greater cortical atrophy and scored significantly higher in frontal and parietal area. Only 4 patients had enlarged ventricles, and there were none with a smaller ventricle. Mean Evan's ratio of patients was lower than that of the control group but the difference was statistically nonsignificant. The mean VBR of patients was lower than that of the control group and the difference was highly significant. Conclusions: The evidence of neuro-radiological abnormalities in patients with OCD suggests that these disorders should not be considered merely functional in the traditional sense.

Possible psychosocial strategies for controlling violence against women
Sapna Kumari, Richa Priyamvada, S Chaudhury, AR Singh, AN Verma, J Prakash
July-December 2009, 18(2):132-134
DOI:10.4103/0972-6748.62275  PMID:21180492
Women, the fair sex, are considered to be the weaker sex and one of the most powerless and marginalized sections of our society. Violence against women and girls continues to be a global epidemic. It is present in every country, cutting across boundaries of culture, class, education, income, ethnicity and age. A growing body of research studies indicates that 20% to 50% (varying from country to country) of women have experienced domestic violence. A multilayered strategy that addresses the structural causes of violence against women is needed. Strategies and interventions attempting to address violence against women should be guided by 5 underlying principles: Prevention, protection, early intervention, rebuilding the lives of victims/survivors and accountability. When planning interventions, there are a variety of stakeholders who should be borne in mind. Key areas for intervention include encouraging women empowerment; advocacy and awareness raising; education for building a culture of nonviolence; encouraging active participation of women in political system; resource development; direct service provision to victims, survivors and perpetrators; networking and community mobilization; direct intervention to help victims/survivors rebuild their lives; legal reform; monitoring interventions and measures; early identification of 'at risk' families, communities, groups and individuals; and data collection and analysis.

Partial Kluver-Bucy syndrome as a delayed manifestation of head injury
PS Bhat, PK Pardal, RC Das
July-December 2009, 18(2):117-118
DOI:10.4103/0972-6748.62272  PMID:21180489
After traumatic brain injury (TBI), the most disabling problems are generally related to neuropsychiatric sequelae, including personality change and cognitive impairment, rather than neurophysical sequelae. Kluver-Bucy syndrome (KBS) is a rare neurobehavioral condition, first described in 1937 as an experimental neurobehavioral syndrome in monkeys with bitemporal brain lesions. The syndrome in man was subsequently observed to be transient or permanent in a variety of neurodegenerative disorders and after traumatic, nontraumatic and infectious brain injury. However, partial KBS may occur in the absence of the classic bilateral temporal lesion, though rare. Pharmacological treatment of post-TBI neuropsychiatric sequelae consists of symptomatic, functional and hypothetical approaches. Specific pharmacological treatment consists of antipsychotics, anti-kindling anticonvulsants or a combination thereof. A case of partial KBS presenting as delayed manifestation of traumatic brain injury that improved with carbamazapine and antipsychotics is presented.

S Subramanian, DV Nithyanandan
July-December 2009, 18(2):108-112
DOI:10.4103/0972-6748.62270  PMID:21180487
Background: Much of the research studies have shown that occupational stress is one of the strong determinant factors of coronary heart diseases among people in general. However, exploring the extent to which the type or nature of ailments and its subsequent risk factors have an effect on the onset of mental health will help evolve suitable preventive measures. The present study attempts to explore the status of mental health and occupational stress with respect to 2 categories of patients: Those who are suffering from cardiac problems and those suffering from noncardiac health problems. Materials and Methods: Occupational Stress Questionnaire and Mental Health Questionnaire were administered to both cardiac and noncardiac patients. The cardiac group consisted of 40 patients who were being treated at the cardiology department of a reputed hospital, and noncardiac group (40 patients) consisted of outpatients of the same hospital being treated for noncardiac problems like knee pain, headache, etc. Responses to these self-reported questionnaires were subjected to statistical analysis to find out the difference between cardiac and noncardiac groups. Results: The results revealed that cardiac patients tend to have lower levels of mental health than noncardiac patients. Similarly, cardiac patients were reported to have higher levels of stress due to role ambiguity, powerlessness, intrinsic impoverishment and unprofitability. Conclusions: The implications of the study were implementation of interventions to improve the internal strength of cardiac patients to overcome various aspects of occupational stress.
