BACKGROUND The identification of distinct subtypes based on comorbidity offers potential utility in understanding variations in the clinical expression of obsessive-compulsive disorder (OCD). Hence, we examined the hypothesis whether patients with OCD with major depressive disorder (MDD) or anxiety disorder comorbidity would differ from those without in terms of phenomenology. METHODS A total of 545 consecutive patients who consulted a specialty OCD clinic during the period 2004 to 2009 at a psychiatric hospital in India formed the sample. They were evaluated with the Yale-Brown Obsessive-Compulsive Scale (YBOCS), the Mini International Neuropsychiatric Interview, and the Clinical Global Impression scale. RESULTS Among 545 patients, 165 (30%) had current MDD, and 114 (21%) had current anxiety disorder comorbidity. Patients with OCD with MDD were mostly women who had a greater severity of OCD symptoms, more of obsessions (especially religious), greater occurrence of miscellaneous compulsions (need to confess or need to touch), higher suicidal risk, and past suicidal attempts. Patients with OCD with anxiety disorder had an earlier onset of illness that was associated with prior life events, less of compulsions, more of aggressive and hoarding obsessions, pathologic doubts, checking, and cognitive compulsions. CONCLUSIONS Obsessive-compulsive disorder, when comorbid with MDD, is more severe and is associated with higher suicidal risk. On the other hand, anxiety disorder comorbidity seems to influence not so much the morbidity but the phenotypic expression of OCD.

BACKGROUND Comorbid anxiety disorders and depression are commonly seen in men with sexual disorders such as erectile dysfunction (ED) and premature ejaculation (PE). However, they are often undiagnosed and untreated, and their relationship to sexual dysfunction is complex. This study examines the frequency and correlates of comorbid anxiety and depression in men with ED or PE. METHODS The case records of 64 men with ED or PE attending a clinic for psychosexual disorders in a general hospital psychiatry unit during the period 2010-14 were reviewed. Information on comorbid anxiety disorders and depression was extracted from these records, and their clinical and demographic associations were analyzed. RESULTS Eight (12.5%) men had comorbid depressive disorders, and fifteen (23.4%) had anxiety disorders. These disorders predated the onset of sexual dysfunction in the majority of patients. Generalized anxiety disorder was the commonest anxiety disorder. Men with comorbid depression had significantly elevated rates of suicidal ideation or behavior related to their sexual dysfunction, and were more likely to report a lack of libido. Men with pre-existing anxiety disorders were more likely to experience performance anxiety related to sex, and to have PE without comorbid ED. CONCLUSIONS Depression and anxiety affect a substantial minority of men with sexual dysfunction. Men presenting for the evaluation of ED and PE should be carefully screened for these disorders. The links between anxiety disorders and sexual performance anxiety merit further investigation in this patient group.

INTRODUCTION Erectile dysfunction (ED) is a common form of male sexual dysfunction. Psychological factors play an important role in the onset and persistence of ED. Disturbed childhood attachment is a biologically and psychologically plausible predisposing factor for psychogenic ED that has not been systematically studied to date. AIM This study aims to assess the frequency and correlates of events associated with parental separation (actual or threatened) and loss in men with a diagnosis of psychogenic ED. METHODS The case records of 46 men who presented to a clinic for psychosexual disorders in the period 2012-2013, and were diagnosed with psychogenic ED using a semi-structured interview schedule, were reviewed. RESULTS Events causing actual or potential disturbed attachment (DA) in childhood were reported by 20 of 46 men with psychogenic ED (43.5%). This group of men (DA+) had an earlier age at onset of ED (median 25 vs. 29 years, P = 0.005), were more likely to be single (15/20 vs. 5/26 (χ(2) = 14.307, P < 0.001), reported sexual performance anxiety more frequently (12/20 vs. 7/26, χ(2) = 5.101, P = 0.024), and were more likely to develop ED in the absence of a proximate stressor (4/20 vs. 15/26, P = 0.015). They also showed a trend toward being more likely to report guilt over early sexual experiences as a contributory factor (5/20 vs. 1/26, P = 0.072). In a binary logistic regression analysis, the presence of performance anxiety (B = 2.01, P = 0.023) and marital status (B = -2.85, P = 0.001) were significantly associated with events causing DA. CONCLUSIONS Disrupted childhood attachment was common in our sample of men with ED and is associated with significant differences in their clinical profile, particularly an earlier onset, a lower likelihood of being married, and higher rates of performance anxiety. This study highlights the need to consider early childhood experiences, particularly using an attachment theory framework, when examining the origins of psychogenic erectile dysfunction.

BackgroundThe management of schizophrenia has seen significant strides over the last few decades, due to the increasing availability of a number of antipsychotics. Yet, the diminished efficacy in relation to the negative and cognitive symptoms of schizophrenia, and the disturbing adverse reactions associated with the current antipsychotics, reflect the need for better molecules targeting unexplored pathways.PurposeTo review the salient features of the recently approved antipsychotics; namely, iloperidone, asenapine, lurasidone and blonanserin.MethodsWe discuss the advantages, limitations and place in modern pharmacotherapy of each of these drugs. In addition, we briefly highlight the new targets that are being explored.ResultsPromising strategies include modulation of the glutamatergic and GABAergic pathways, as well as cholinergic systems.ConclusionsAlthough regulatory bodies have approved only a handful of antipsychotics in recent years, the wide spectrum of targets that are being explored could eventually bring out antipsychotics with improved efficacy and acceptability, as well as the potential to revolutionize psychiatric practice.

Self-inflicted eye injuries are rare but a devastating consequence of a serious mental disorder. Bilateral self-enucleation also known as oedipism has been documented in ancient texts and myths. Various biologic, psychologic, and social theories have been put forward to explain this rare phenomenon. In this report, we describe a case of oedipism, which highlights the influence of sociocultural factors on the psychopathology in acute transient psychotic disorder.

Introduction. Recent research has drawn attention to the link between childhood maltreatment and schizophrenia. Child abuse and neglect may have an impact on symptoms and physical health in these patients. This association has not been studied to date in India. Materials and Methods. Clinically stable patients with schizophrenia (n = 62) were assessed for childhood adversity using the Childhood Trauma Questionnaire. The association of specific forms of adversity with symptomatology and associated variables was examined. Results. Emotional abuse was reported by 56.5% patients and physical abuse by 33.9%; scores for childhood neglect were also high. Persecutory delusions were linked to physical abuse, while anxiety was linked to emotional neglect and depression to emotional abuse and childhood neglect. Physical abuse was linked to elevated systolic blood pressure, while emotional abuse and neglect in women were linked to being overweight. Conclusions. Childhood adversity is common in schizophrenia and appears to be associated with a specific symptom profile. Certain components of the metabolic syndrome also appear to be related to childhood adversity. These results are subject to certain limitations as they are derived from remitted patients, and no control group was used for measures of childhood adversity.

Secretion of the anterior pituitary hormone prolactin can be significantly increased by antipsychotic drugs, leading to a range of adverse effects in patients with schizophrenia. However, there is evidence from a variety of studies that prolactin may also be related to symptom profile and treatment response in these patients, and recent work has identified variations in prolactin secretion even in drug-free patients. In this paper, a selective review of all relevant studies pertaining to prolactin and schizophrenia, including challenge and provocation studies, is presented. The implications of this work are discussed critically. A tentative model, which synthesizes these findings and argues for a significant role for prolactin in the development of schizophrenia, is outlined.

Background: Early onset (EO) alcohol dependence (AD) has been found to represent a subtype of alcoholism with a distinct profile and prognosis compared to late onset (LO) alcohol dependence. Externalizing disorders, especially attention deficit hyperactivity disorder (ADHD) that may continue as attention deficit hyperactivity disorder, residual type (ADD, RT) in adulthood, may increase susceptibility to early-onset AD. Aims: To examine the relationship between ADHD and ADD, RT symptoms and age at onset of AD in a sample of Indian male patients. 70 male subjects with AD presenting to the De-Addiction Services of the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore, were studied. The study had a retrospective design. Materials and Methods: Patients were examined for evidence of past ADHD in childhood and current ADD, RT using structured instruments. Chi-square tests and odds ratios were used to express the relative risk of association of ADHD with early- and late-onset AD. Results: Significantly more EO alcoholics (19/30, 63.3%) had a history of ADHD in childhood compared to LO alcoholics (7/28, 25%, P < 0.05) ADD, RT was also over-represented in EO probands. Conclusions: The results of this study are consistent with previous research that shows a high incidence of ADHD in early-onset alcoholics. This may have important management implications.

Background: Suicides are among the most important causes of death in the economically productive population. Characteristics of impulsive and nonimpulsive suicide attempters may differ which would have a bearing on planning preventive measures. Aims: This study aimed to characterize the clinical and psychological profile of impulsive and nonimpulsive suicide attempters. Settings and Design: This retrospective comprehensive chart-based study was conducted at a tertiary care hospital in South India. Methods: The study utilized records of patients over a period of 3 years. An attempt was considered impulsive if the time between suicidal idea and the attempt was <30 min. Stressful life events were assessed using presumptive stressful life events scale; hopelessness was evaluated using Beck Hopelessness Scale (BHS) and coping was measured using Coping Strategies Inventory Short Form. Statistical Analysis Used: Impulsive and nonimpulsive suicide attempters were compared using appropriate inferential statistical tests. Results: Of 316 patients, 151 were classified as having an impulsive suicidal attempt (47.8% of the sample). The impulsive and nonimpulsive suicide attempters did not differ on demographic characteristics. Use of natural plant products was more common in impulsive attempters (27.2% vs. 12.7%), while physical methods like hanging was less common (0.7% vs. 7.3%). Those with an impulsive attempt were more likely to have a recent contact with a health professional (24.5% vs. 4.5%). Impulsive suicide attempters had higher scores on BHS (Mann–Whitney U = 7680.5, P < 0.001), and had recollected greater number of stressors. Conclusion: Impulsive suicide attempters differ from nonimpulsive suicide attempters in clinical features like methods of attempt, presence of hopelessness, and stressors.

INTRODUCTION Dhat syndrome is a condition described in the Indian subcontinent, in which patients present with concerns about loss of semen. Though this condition has been conceptualized as a culture-bound syndrome, some authors have also considered it a manifestation of depression. This calls for a closer examination of the possible genetic link between Dhat syndrome and depression. METHOD We examined the relationship between Dhat syndrome and the depressive spectrum, as conceptualized by Winokur, using a retrospective design. The case records of 46 patients with Dhat syndrome were reviewed, and patients were divided into two groups - family history positive (FH+) and family history negative (FH-) - based on the presence of depressive spectrum conditions in first degree relatives. These two groups were compared in terms of demographic variables, symptom profile and comorbidity. RESULTS The FH+ group had significantly higher rates of depressive disorders and substance use disorders (alcohol and nicotine dependence). They were also more likely to report concerns about penile size. DISCUSSION These results suggest that a subgroup of patients with the Dhat syndrome can be viewed as suffering from a depressive spectrum disorder. Dhat syndrome may be better understood as a heterogeneous group than as a single diagnostic entity. Identifying such sub-groups can help in choosing optimal treatments for patients with Dhat syndrome, such as selecting antidepressants for the group described in this study.
