Abstract
The use of pharmaceuticals to treat Major Depressive Disorder (MDD) has several drawbacks, including severe side effects. Natural compounds with great efficacy and few side effects are in high demand due to the global rise in MDD and ineffective treatment. Yohimbine, a natural compound, has been used to treat various ailments, including neurological conditions, since ancient times. Serotonergic neurotransmission plays a crucial role in the pathogenesis of depression; thus, serotonergic receptor agonist/antagonistic drugs are promising anti-depressants. Yohimbine was investigated in this study to determine its antidepressant activity using molecular docking and pharmacokinetic analyses. Additionally, the in silico mutational study was carried out to understand the increase in therapeutic efficiency using site-directed mutagenesis. Conformational changes and fluctuations occurring during wild type and mutant serotonergic receptor, 5-hydroxytryptamine receptors 1A (5HT1A) and yohimbine were assessed by molecular dynamics MD simulation studies. Yohimbine was found to satisfy all the parameters for drug-likeness and pharmacokinetics analysis. It was found to possess a good dock score and hydrogen-bond interactions with wild type 5HT1A structure. Our findings elaborate the substantial efficacy of yohimbine against MDD; however, further bench work studies may be carried out to prove the same.

Abstract
Bereavement is the state of loss, determined in most of the cases by the death of a close person. It is probably the greatest sorrow that can occur in an individual life. Grief is a normal, healthy response to loss, evolving through stages in the process of mourning. In some cases, bereavement may lead to the outburst of manic episode: despite literature data being scarce, reports have explored this important clinical entity, variously called as "funeral mania" or "bereavement mania". We systematically reviewed the literature exploring the possible relationships between bereavement and the onset of a manic episode, both first or recurrent pre-existing episode, besides describing a case report on a manic episode in the aftermath of a loss event, with an accurate evaluation of prior mild mood spectrum instability, supporting the role of loss-events as potential risk factor for bipolar illness progression. This article tries summarizing existing evidence on the debate whether clinicians should consider mania as a possible bereavement reaction.

Abstract
BACKGROUND Causes for a seasonal impact on admissions for mania remain to be clarified. We examined the impact of photoperiod, rate of change of photoperiod and hours of sunshine on admissions over an extended period. METHODS Monthly admission data to NSW psychiatric hospitals for more than twenty thousand patients admitted for mania over a fifteen-year period were correlated with photoperiod and sunshine changes. RESULTS While the peak in admissions occurred in spring, the shift in admissions being under-represented to being precipitously over-represented corresponded with the photoperiod commencing to increase in winter (i.e. July). Analyses identified rate of change in photoperiod as somewhat more influential than change in photoperiod and with hours of sunshine not making a distinctive contribution. Immediate and delayed impacts of rate of change as well as change in photoperiod across the whole year accounted for a distinctive 20% of the variance in hospital admissions. LIMITATIONS Validity of mania diagnoses cannot be established from the data set, admission data were obtained from across the state while meteorological data were obtained from the capital city, lag periods between onset of a mania and hospitalization (while identified) would impact on associations, social factors were not included and study associations do not imply causality. CONCLUSIONS The lack of a strong year-long correlation may reflect photoperiod changes being only a weak causal factor or that its influence may be through a strong impact phase after the winter solstice and with the spring peaking of admissions reflecting secondary photoperiod or other influences.

Abstract
BACKGROUND Studies have established higher rates of hospitalization for mania in spring and summer and posit various explanatory climatic variables. As the earth's climate is changing, we pursue whether this is reflected in the yearly seasonal variation in hospitalizations for mania. This would be indicated by the presence of secular changes in both the hospitalization seasonal pattern and climatic variables, and associations between both variable sets. METHODS Data were obtained for 21,882 individuals hospitalized to psychiatric hospitals in the Australian state of New South Wales (NSW) over a 14-year period (2000-2014) with ICD-diagnosed mania - and with NSW population figures and salient climatic variables collected for the same period. Regression analyses were conducted to examine the predictive value of climate variables on hospital admissions. RESULTS Data quantified a peak for manic admissions in spring of the southern hemisphere, in the months of October and November. There was a significant linear increase in manic admissions (0.5%/year) over the 14-year time period, with significant variation across years. In terms of climatic variables, there was a significant linear trend over the interval for solar radiation, although the trend indicated a decrease rather than an increase. Seasonal variation in admissions was most closely associated with two climate variables - evaporation in the current month and temperature in the previous month. LIMITATIONS Hospitalization rates do not necessarily provide an accurate estimate of the onset of manic episodes and findings may be limited to the southern hemisphere, or New South Wales. CONCLUSIONS While overall findings do not support the hypothesis that climate change is leading to a higher seasonal impact for manic hospital admissions in the southern hemisphere, analyses identified two climate/weather variables - evaporation and temperature - that may account for the yearly spring excess.

Abstract
This report describes a novel cognitive-behavioral intervention aimed to increase self-esteem, in a lady with a diagnosis of bipolar illness. It is argued that self-esteem is important to the development, maintenance, and relapse of the illness symptoms, being both a vulnerability factor to, and a consequence of, illness episodes. The intervention involves modification of the strength of positive beliefs about the self through the focus of attention on specific behavioral examples of the patient’s positive attributes. The intervention is described in detail and results over the longer term are reported. There were significant improvements on measures of self-esteem, which was in the normal range at posttreatment and follow-up. General psychotic psychopathology improved by 20% and there was an improvement in social functioning over one standard deviation. Results at 3- and 12-month follow-ups indicate that improvements were largely maintained although there was some reduction in the magnitude of improvement.

Interaction of DRD2TaqI, COMT, and ALDH2 genes associated with bipolar II disorder comorbid with anxiety disorders in Han Chinese in Taiwan. Metab Brain Dis 2015; 30:755-65.

Abstract
It is hypothesized that dopaminergic genes-dopamine type-2 receptor (DRD2), aldehyde dehydrogenase 2 (ALDH2), and catechol-O-methyltransferase (COMT)-are associated with bipolar disorder (BP) and anxiety disorder (AD). Bipolar II (BP-II) is reported to be highly comorbid with AD. We examined whether interactions among these three genes are susceptibility factors in BP-II with AD (BP-II(+AD)) and without AD (BP-II(-AD)). In this study, we hypothesize that the interaction of the dopaminergic genes between BP-II(+AD) and BP-II(-AD) is significant different. We recruited 1260 participants: 495 with BP-II(-AD), 170 with BP-II(+AD), and 595 healthy controls without BP-II or AD. Genotyping was done using polymerase chain reactions plus restriction fragment length polymorphism analysis. Genotypic frequencies of the DRD2TaqIA, COMT, and ALDH2 polymorphisms between the two BP-II groups were nonsignificant. In logistic regression, the ALDH2 and DRD2TaqIA genes showed a main effect that was protective against BP-II(-AD) (odds ratio [OR] = 0.497, p = 0.010, and OR = 0.415, p = 0.017, respectively). The interaction of DRD2TaqIA A1/A1 and ALDH2*1/*1 had a significant risk effect on the BP-II(-AD) group (OR = 7.177, p < 0.001). However, the interaction of DRD2TaqIA A1/A1, ALDH2*1/*1, and COMTMet/Met&Val/Met become a weak protective factor against BP-II(-AD) (OR = 0.205, p = 0.047). All of the significant results described above are found only in BP-II(-AD). This study supports the hypothesis the interaction of the dopaminergic genes between BP-II(+AD) and BP-II(-AD) is significant different,, and provides additional evidence that the DRD2TaqIA A1/A1, ALDH2*1/*1 and COMT genes interact in BP-II(-AD) but not in BP-II(+AD).

Abstract
Findings on the association between the risk for developing bipolar disorder and the functions of the serotonin transporter-linked polymorphic region gene (5-HTTLPR) and dopamine D2 receptor gene (DRD2) variants are contradictory. One explanation for this is that a gender difference may exist for genetic contributions. We compared the gender-related main effects and the gene-to-gene interaction between serotonin transporter gene (SLC6A4) and DRD2 in adult male and female patients with bipolar I (BP-I) and bipolar II (BP-II) disorder. Patients with BP-I (n = 400) and BP-II (n = 493), and healthy controls (n = 442) were recruited from Taiwan's Han Chinese population. The genotypes of the 5-HTTLPR and DRD2 Taq-IA polymorphisms were determined using polymerase chain reaction-restriction fragment length polymorphism analysis. Logistic regression analysis showed a significant gender-specific association of the DRD2 A1/A1 and the 5-HTTLPR S/S, S/LG , and LG/LG (S+) (p = 0.01) genotypes in men with BP-I (p = 0.002 and 0.01, respectively) and BP-II (p = 0.001 and 0.007, respectively), but not in women. A significant interaction for the DRD2 A1/A1 and 5-HTTLPR S+ polymorphisms was also found only in men with BP-I and BP-II (p = 0.003 and 0.001, respectively). We provide preliminary evidence for a gender-specific effect of the SLC6A4 and DRD2 gene variants for the risk of BP-I and of BP-II. We also found gender-specific interaction between 5-HTTLPR and DRD2 Taq-IA polymorphisms in patients with bipolar disorder.

Abstract
Dextromethorphan (DM) is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist that may be neuroprotective for monoamine neurons. We hypothesized that adding DM to valproate (VPA) treatment would attenuate bipolar disorder (BP) symptoms. We evaluated in BP patients the association between the DRD2/ANKK1 TaqIA polymorphism with treatment response to VPA+add-on DM and to VPA+placebo. This double-blind, stratified, randomized study ran from January 2007 through December 2010. BP patients undergoing regular VPA treatments were randomly assigned to groups given either add-on DM (60 mg/day) (n=167) or placebo (n=83) for 12 weeks. The Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HDRS) were used to evaluate clinical response. The genotypes of the DRD2/ANKK1 TaqIA polymorphisms were determined using polymerase chain reactions plus restriction fragment length polymorphism analysis. To adjust within-subject dependence over repeated assessments, multiple linear regression with generalized estimating equation methods was used to analyze the effects of the DRD2/ANKK1 TaqIA polymorphism on clinical performance. Both groups showed significantly decreased YMRS and HDRS scores after 12 weeks of treatment; the differences between groups were non-significant. Decreases in YMRS scores were greater in patients with the A1A1 (P=0.004) genotypes than with the A2A2 genotype. We conclude that the DRD2/ANKK1 TaqIA polymorphism influenced responses to DM by decreasing manic symptoms in BP patients.

Abstract
OBJECTIVES. Clarifying the association between bipolar I and bipolar II disorders at the genetic level is essential for improving our understanding of them. In this study, we evaluated the hypothesis that the dopaminergic polymorphisms are risk factors for bipolar disorders. We examined the association between the catechol-O-methyltransferase (COMT) Val158Met and dopamine D3 receptor (DRD3) Ser9Gly polymorphisms and bipolar I and II disorders, as well as possible interactions between these genes. METHODS. Seven hundred and eleven participants were recruited: 205 with bipolar I, 270 with bipolar II, and 236 healthy controls. The genotypes of the COMT Val158Met and DRD3 Ser9Gly polymorphisms were determined using polymerase chain reactions plus restriction fragment length polymorphism analysis. RESULTS. Logistic regression analyses showed a statistically significant main effect for the Met/Met genotype of the COMT Val158Met polymorphism (P=0.032) and a significant interaction effect for the Met/Met genotype of the COMT Val158Met and Ser/Ser genotypes of the DRD3 Ser9Gly polymorphism (P=0.001) predicted bipolar I patients. However, there was no association between the COMT Val158Met or DRD3 Ser9Gly and bipolar II. CONCLUSIONS. We provide initial evidence that the COMT Val158Met and DRD3 Ser9Gly genotypes interact in bipolar I and bipolar II disorders and that bipolar I and bipolar II are genetically distinct.

Abstract
BACKGROUND There has been growing interest in investigating religion as a relevant element in illness outcome. Having religious beliefs has been shown repeatedly to be associated with lessened rates of depression. Most of the limited published research has been restricted to elderly samples. Religious coping is thought to play a key role in religion's effects. Strangely, psychiatric research has neglected this area. METHODS A questionnaire covering religious, spiritual and philosophical beliefs and religious practice was given to a sample of patients with bipolar affective disorder in remission. RESULTS Most patients often held strong religious or spiritual beliefs (78%) and practised their religion frequently (81.5%). Most saw a direct link between their beliefs and the management of their illness. Many used religious coping, and often religio-spiritual beliefs and practice put them in conflict with illness models (24%) and advice (19%) used by their medical advisors. LIMITATIONS This was a cross-sectional design without a control group and thus it is not possible to determine causal associations from the data set. CONCLUSIONS Religio-spiritual ideas are of great salience to many patients with bipolar disorder and shape the ways in which they think about their illness. Many reported experiencing significant paradigm conflict in understanding and managing their illness between medical and their spiritual advisors. These data suggest that the whole area of religion and spirituality is directly relevant to people living with a chronic psychiatric illness and should be firmly on the discussion agenda of clinicians working with patients with bipolar disorder.

Abstract
Postpartum psychosis is a rare but severe psychiatric disorder. Its diagnostic status remains controversial, but several studies have shown that the majority of patients who develop psychosis immediately following childbirth suffer from bipolar disorder. The pathophysiology of postpartum psychosis is poorly understood, but factors such as primiparity, difficult labor, genetic predisposition, and hormonal changes have been suggested as etiological factors. This paper reviews the literature on the relationship of sleep disruption and postpartum psychosis. It is argued that sleep loss resulting from the interaction of various putative causal factors may be the final common pathway in the development of psychosis in susceptible women. Clinical significance of these findings, including strategies to prevent postpartum psychosis, are discussed and suggestions are made for future research directions.

Abstract
BACKGROUND Based on the dopamine hypothesis, the dopamine D1 receptor gene (DRD1) is considered to be a good candidate gene for bipolar disorder (BP). METHODS In our study, three polymorphisms of the DRD1 gene, -800T/C, -48A/G, and 1403T/C, were analyzed in 286 BP trios. Both the transmission disequilibrium test (TDT) and haplotype TDT were performed on the genotype data to test for the presence of linkage disequilibrium between DRD1 and bipolar disorder. With the extended transmission disequilibrium test (ETDT), we also calculated the maternal transmission and paternal transmission for each allele. RESULTS Although no association was found for each individual polymorphism, there is a significant association between DRD1 and BP for haplotype TDT analysis (chi(2) = 16.068, df = 3, p =.0011). CONCLUSIONS These results indicate that DRD1 may play a role in the etiology of bipolar disorder.

Abstract
Despite modern treatments, bipolar disorder remains a chronic, relapsing disorder that leads to long-term psychosocial disability. A review of the literature suggests that while employment rates amongst individuals with bipolar disorder may improve over time, and are relatively better compared to some other chronic mental disorders, employment prospects do not match the high scholastic achievements seen amongst this group of people before the onset of their illness. For those with bipolar disorder, clinical recovery does not necessarily mean functional recovery, and the usual early age of onset may further reduce an individual's preparedness for employment. Two brief vignettes are used to discuss how occupational therapists can help their clients maintain their sense of hope in vocational recovery, gain better self-awareness and work with clients at various stages of recovery rather than waiting for full functional recovery. Further research is required to help identify specific factors that contribute to the success of employment integration amongst people with bipolar disorder.

BACKGROUND Successful management of major mental illness in the community relies significantly on an informal or non-professional network of caregivers. The needs and experiences of such caregivers have been little studied with respect to major chronic mood disorders. METHOD A sample of caregivers (n=41) of RDC bipolar disorder was systematically interviewed to determine how this role affected them. RESULTS Caregivers reported significant difficulties in their relationships with the patient when s/he was unwell, with considerable impact on their own employment, finances, legal matters, co-parenting and other social relationships. Violence was a particular worry for partner/parent caregivers of both male and female patients when the patient was manic. The caregiver's own mental health appeared unaffected. Despite this, the caregivers appeared emotionally committed to the patients and showed considerable tolerance of problem behaviours, which they rank-ordered for difficulty. Among nonfamily partners, knowledge of the illness before cohabitation was poor. LIMITATION The sampling does not capture caregivers who have abandoned their role, such as spouses who have divorced the bipolar sufferer. CONCLUSIONS Management of this illness requires a partnership between mental health professionals and the informal caregivers and the authors suggest that each group needs to understand the difficulties encountered by the other. Although erosion of relationships is a well-known complication of bipolar disorder, findings indicate that treating clinicians can rely on caregivers committed to the welfare of the patient.

Abstract
In most African district hospitals there are no separate facilities for psychiatric patients. Aformer general medical officer describes how a ward for these patients was set up at a rural district hospital in Zimbabwe using the already available resources. The effects on the psychiatric care at the hospital and the district are illustrated by two case reports. It is concluded that psychiatric care integrated in primary healthcare, with due regard for the cultural aspects and with cooperation of local healers is feasible, provided that it is supported by additional diagnostic and treatment facilities at the district hospital.

Abstract
Bipolar disorder is a major psychiatric illness that has evidence for a significant genetic contribution toward its development. In recent years, the BalI RFLP (restriction fragment length polymorphism) in the dopamine D3 receptor gene has been examined as a possible susceptibility factor for both schizophrenia and bipolar disorder. While analysis in schizophrenia has produced examples of increased homozygosity in patients, less encouraging results have been found for bipolar disorder. Recently, however, a family-based association study has found a significant excess of allele 1 and allele 1-containing genotypes in transmitted alleles to bipolar probands over nontransmitted controls. In a large bipolar case control sample (n = 454), we have been unable to replicate the family-based association study (chi-square = 0.137, P = 0.71, 1 df) or detect an effect similar to the positive homozygosity findings in schizophrenia (chi-square = 0.463, P = 0.50, 1 df). A meta-analysis of previous association studies also revealed no difference in allele distributions between bipolar patients and controls for this polymorphism in ethnically homogeneous samples (odds ratio, OR, = 1.04; P = 0.60; 95% confidence interval, CI, = 0.89-1.20). In view of this evidence, we conclude that variation at the BalI RFLP is not an important factor influencing the susceptibility to bipolar disorder. It remains possible, however, that other sequence variations within the DRD3 gene could play a role.

Abstract
Estrogen and thyroid hormones exert effects on growth, development, and differentiation of the nervous system. Hormone administration can lead to changes in behavior, suggesting that genetic variants of the estrogen receptor alpha (ERalpha) and the thyroid hormone receptor alpha (TRalpha) genes may predispose to psychiatric diseases. To investigate this possibility, regions of likely functional significance (all coding exons and flanking splice junctions) of the ERalpha and TRalpha genes were scanned in patients with schizophrenia (113), along with pilot studies in patients with bipolar illness (BPI), puerperal psychosis, autism, attention-deficit hyperactivity disorder (ADHD), and alcoholism. A total of 1.18 megabases of the ERalpha gene and 1.16 megabases of the TRalpha gene were scanned with Detection of Virtually All Mutations-SSCP (DOVAM-S), a method that detects virtually all mutations. Four missense mutations, seven silent mutations and one deletion were identified in the ERalpha gene, while only four silent mutations were present in the TRalpha gene. Two of the missense mutations in ERalpha are conserved in the six available mammalian and bird species (H6Y, K299R) and a third sequence variant (P146Q) is conserved in mammals, birds, and Xenopus laevis, hinting that these sequence changes will be of functional significance. These changes were found in one patient each with BPI, puerperal psychosis, and alcoholism, respectively. Analysis of the ERalpha and TRalpha genes in 240 subjects reveals that missense changes and splice site variants are uncommon (1.7% and 0%, respectively). Further analyses are necessary to determine if the missense mutations identified in this study are associated with predisposition or outcome for either psychiatric or nonpsychiatric diseases.

Abstract
This preliminary study explored the perceptions of illness of people in a public hospital setting for treatment of bipolar disorder. Fifteen inpatients (5 African Americans, 5 Hispanics, and 5 European Americans) participated in audio-recorded, structured interviews. The interviews were designed to identify recurring themes and patterns in their perceptions of bipolar disorder and to assess their cognitive representations of the illness. The interviews were transcribed verbatim, and content analysis procedures were used to identify the illness perceptions and to compare them based upon ethnic orientation. Results indicated that most of the participants' group responses were more alike than they were different. However, discrete themes emerged among the individuals as their stories unfolded. These themes, and the perceived benefit of the interview itself, provide a beginning foundation for further research in the area, and have clinical relevance for health care providers working with this population.

Abstract
BACKGROUND Discrepancy between efficacy of prophylactic lithium and its effectiveness in ordinary clinical practice necessitates long-term follow-up data from specialised lithium clinics. Also, role of psychosocial factors in influencing the outcome is unclear. METHODS One hundred and eighteen patients of bipolar affective disorder attending a lithium clinic were followed-up for approximately 11 years (range 2-27 years). Demographic and clinical data, measures of social support and psychosocial stress were obtained at the intake in 1989-1990. Study design combined retrospective chart-review (till the time of intake) with prospective follow-up till July 1995. RESULTS On lithium, the patients had a mean of 0.43 relapses per year (manic, 0.26; depressive, 0.17) which was significantly less (p < 0.01) than the pre-lithium episode frequency. The figure for entirely relapse-free patients was 24%, and 62% had relapses up to one episode per year (median = 0.3 per year). Fifty-eight (49%) patients were good responders to lithium (relapses < or = 0.30 per year). In comparison to good responders, partial/poor responders had a significantly greater number of pre-lithium depressive episodes, poor lithium compliance, more psychosocial stress and lower social support at intake. These variables correlated well with relapses and explained 32% of the variance of the data. CONCLUSIONS Lithium had a definite prophylactic effect on long-term outcome. Social support and stressful life events are significant correlates of response to lithium. CLINICAL IMPLICATIONS Lithium prophylaxis of bipolar affective disorders seems justified though psychosocial factors appear to modulate its effectiveness. LIMITATIONS Other psychotropic medications were used during relapse and the assessment of psychosocial factors was cross-sectional.

Abstract
We explored cross-sectionally the roles in bipolar spectrum symptomatology of two broad motivational systems that are thought to control levels of responsiveness to cues of threat and reward, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS). Undergraduate students (n = 357) completed questionnaires regarding (a) bipolar spectrum disorders [the General Behavior Inventory (GBI), a well-established clinical screening measure], (b) current depression and mania symptoms (the Internal State Scale; ISS), and (c) BIS/BAS sensitivities (the BIS/BAS scales). Validated cutoff scores on the GBI were used to identify individuals at risk for a mood disorder. It was hypothesized that, among at-risk respondents, high BAS and low BIS levels would be associated with high current mania ratings, whereas low BAS and high BIS would be associated with high current depression ratings. Multiple regression analyses indicated that, among at-risk individuals (n = 63), BAS accounted for 27% of current mania symptoms but BIS did not contribute. For these individuals, BAS and BIS were both significant and together accounted for 44% of current depressive symptoms.

Abstract
Developing family treatments for patients with severe and persistent psychiatric disorder begins at the basic research level, through identifying psychosocial variables that have prognostic significance. Treatment protocols informed by this basic research can then be designed, manualized, and piloted. Next, the efficacy of a new treatment is examined, first in a randomized trial and then, if successful, in a community effectiveness study. We describe this treatment development pathway in a population for whom family attributes have prognostic importance: patients with bipolar affective disorder. The methodological complexities of psychosocial treatment studies are many. Moreover, the results of these studies often reflect interactions between treatment, process, and outcome variables.

Abstract
OBJECTIVE The effectiveness of lithium in preventing recurrences of bipolar disorder was examined prospectively for 2 years in two representative samples of bipolar I patients being treated in a comprehensive program following recommended guidelines. METHOD One hundred and twenty patients were recruited from consecutive admissions to two catchment area psychiatric services (one in the United Kingdom, the other in New Zealand). They were seen at 3-monthly intervals by a member of the research team. Treatment was adjusted according to clinical needs. RESULTS Overall, two-thirds of the patients had a recurrence. Of the 57 on lithium as sole treatment, 39 (68%) had a further episode; 17 after stopping lithium. The 42 on other mood stabilisers and/or an antipsychotic, with or without lithium, did no better. By contrast, only eight (38%) of the 21 who were taking no prophylactic medication had a recurrence. CONCLUSIONS Lithium is much less effective in clinical practice than would be expected from clinical trial results. A major reason for this is poor compliance. Alternative treatment strategies are needed to improve the outcome for bipolar disorder patients.

Abstract
The rationale and design of a large, multicentre, prospective follow-up study on the outcome of severe mental disorders is presented. The study is currently under way in Italy, where psychiatric care has been uniquely characterised since 1978 by the statutory prohibition of admitting patients to psychiatric hospitals. The main purpose of the study is to describe the 5-year outcome of patients with a diagnosis of schizophrenia, paranoid disorder, affective psychosis, reactive psychosis or personality disorder with respect to five areas (clinical condition, personal autonomy, work, and family and social relationships); a secondary objective is to describe the heterogeneity of practices and resources of psychiatric services. The study is being carried out by 76 outpatient psychiatric services throughout the country, covering approximately one-tenth of the Italian population.

Abstract
Nine bipolar patients (2 men and 7 women) and 12 healthy control subjects completed overnight sampling for serum melatonin (MT) and urinary 6-sulphatoxymelatonin (aMT6s). The patients were investigated during manic, depressed, and/or euthymic states. Although serum MT levels did not differ significantly across the bipolar groups, in all cases serum MT levels were significantly lower than in control subjects. Differences in MT levels were also present between bipolar patients who were in a depressed phase and control subjects. There were no statistically significant differences in urinary aMT6s levels among the patients and control subjects, although in all cases nocturnal aMT6s levels were significantly higher than daytime levels. This study provides tentative evidence for decreased serum MT as a trait but not a state marker in bipolar affective disorder.

Abstract
A total of 21 recovered bipolar patients on prophylactic treatment were prospectively followed up for a period of 1 year. Data for major recurrences were retrospectively collected for an additional 3-year period. During the entire 4-year period, over half of the patients (52%) had no major affective recurrences. Eight patients experienced a major depressive episode, while only two experienced a manic one. Psychosocial and clinical variables were assessed at entry to the study. The effect of these variables on the subsequent 4-year illness course was analysed using survivorship curves. The results show that the following psychosocial variables significantly predicted the occurrence of a major affective episode: low level of social support, maladjustment in social and leisure activities, and poor quality of relationships with extended family. In contrast, clinical variables which characterize illness history were not significantly associated with major recurrences.

Abstract
There is a new movement toward delivering manualized, empirically validated psychotherapies in combination with pharmacologic maintenance in the outpatient treatment of bipolar disorder. This article describes the specific goals of psychotherapy with bipolar patients: modifying social risk factors, enhancing medication adherence, increasing the patient's and family's willingness to accept the reality of the disorder, and reducing suicidal risk. It also reviews the nature and underlying assumptions for two new psychotherapies: a family psychoeducational treatment and an individual treatment. Problems in delivering new treatments in the era of managed care, and some solutions to these problems, are also discussed.

Abstract
A conceptual model was developed during interviews with 33 participants that depicts the processes of information search and self-management of hospitalized people with bipolar disorder. Grounded theory methodology guided data collection and analysis. Barriers were reported as encountered throughout the processes; denial of the disorder was the most prevalent obstacle. Critical areas of intervention are helping the person accept the disorder and achieving the basis to be motivated for self-management. Recommendations are for relapse reduction programs to be structured on the awareness that relapse is most likely to occur when barriers are encountered, and that people with the disorder perceive barriers to be everywhere.

In a sample of 213 mood disorder subjects on long-term lithium treatment, we analyzed the recurrence indices of relapses during the prophylactic treatment period. The differences found in the recurrence rates were due to the current age and age of onset, duration of illness and polarity of the probands. The patients with personality disorders showed the worst relapse indices and could represent a group of mood disorder subjects with a bad outcome of lithium treatment.

Abstract
The recently cloned dopamine D3 receptor (DRD3) gene is of potential relevance to the aetiology of bipolar disorder because of an almost exclusive expression in limbic tissue, the region of the brain putatively responsible for control of emotion. We therefore aimed to determine whether bipolar disorder in nine pedigrees (with 171 members) was linked to this receptor gene, which has been mapped to chromosomal region 3q 13.3. Linkage of bipolar disorder and recurrent depression to the DRD3 gene was tested using a series of autosomal dominant and recessive models with varying penetrance levels. Additionally, linkage was examined using a series of levels of definitions of affective illness (ranging from bipolar I alone to all affective disorders). Close linkage to the DRD3 gene was strongly excluded using each model and definition, and these conclusions persisted when a wide range of rates of 'sporadic' (non-genetic) presentations of illness were incorporated in the analysis.

Seasonality of admissions for mania has been commonly reported. Most reports are from temperature zones. We analyzed admissions for mania covering a 9 year period and looked for any seasonal trends using existing methods. No seasonal variation was found. The hospital lies in the tropical zone with a relatively constant climate. This may influence the seasonal pattern of relapses in affective disorder.

Abstract
A potential role of dopamine in bipolar disorder has been suggested by several strands of evidence, namely the ability of dopaminergic agonists to induce mania and the effects of lithium, carbamazepine and the antipsychotics on central dopamine receptors and/or turnover. We therefore aimed to determine if bipolar disorder in two large bipolar pedigrees was linked to the recently cloned dopamine D1 (DRD1) and D2 (DRD2) receptors. (These have been mapped to chromosomal regions 5q35.1 and 11q22.3-q23, respectively). Linkage of bipolar disorder and recurrent depression to DRD1 and DRD2 was tested using a series of genetic models with varying penetrance levels. Additionally, linkage was examined using a series of levels of definitions of affective status (ranging from bipolar I alone to all affective illnesses). Close linkage to these markers was strongly excluded using each model and definition. The findings for DRD1 also persisted when a wide range of rates of 'sporadic' (non-genetic) presentations of illness were incorporated in the analysis, but the DRD2 results did not remain statistically significant at high sporadic rates. The exclusion of linkage to DRD2 is consistent with other recent reports.

Abstract
In a 2 year study of life events and relapse in a cohort of 62 patients with bipolar affective disorder, an excess of events was found during the month immediately preceding relapse. Of 52 relapses 19% were preceded by a severe event in the previous month, compared to a background rate of 5% of patients experiencing a severe event each month at other times. The rate of life events prior to relapse was not apparently different between manic and depressive relapse, though the number of depressive episodes was small.

Abstract
The long-term treatment outcome of 248 bipolar patients in an out-patient lithium programme was assessed. Over half of the patients (138 or 56%) had no affective episodes in the year observed. Patients were divided into outcome groups according to GAS scores: the outcome for 40% of patients was good, for 41% fair, and for 19% poor. More frequent psychiatric admissions before starting lithium treatment was the best predictor of poor outcome, followed by a negative affective style in the family and lower social class. Current alcohol and drug abuse was associated with poor outcome. Although familial and psychosocial factors were significantly associated with outcome, the findings suggest there may be inherent differences in the pathophysiology of bipolar disorder reflected in an increased frequency of episodes which account for a large variance in lithium treatment outcome.

Abstract
Techniques of behavioral family management (BFM), which have been found to be highly effective in delaying relapse for schizophrenic patients when used as adjuncts to medication maintenance, are also applicable in the outpatient treatment of recently hospitalized bipolar, manic patients. The authors describe their adaptation of the educational, communication skills training, and problem-solving skills training modules of BFM to families containing a bipolar member. The observations that families of bipolar patients are often high functioning, and that these families seem to enjoy interchanges that are highly affective and spontaneous, led to certain modifications in the original BFM approach. The authors found it necessary to be (a) more flexible and less didactic, (b) more oriented toward dealing with affect and resistance to change, and (c) more focused on the patient's and family members' feelings about labeling, stigmatization, and medication usage. Research issues relevant to testing the efficacy of this approach are also discussed.

Abstract
This paper examines the seasonal variation in manic admissions over a five year period in New Zealand. There is a significant monthly variation in admission rates with a spring/summer peak. Breakdown by sex, age and admission status suggested that there is no particular subgroup responsible, but that young first admissions and older female readmissions do not follow this trend. Examination of the monthly admission rates revealed that this peak is not constant from year to year. Possible mechanisms, which link fluctuating environmental variables with an irregular spring/summer peak for manic admissions, are discussed.
