The association between childhood adversities and subsequent first onset of psychotic experiences: a cross-national analysis of 23 998 respondents from 17 countries

BACKGROUND

Although there is robust evidence linking childhood adversities (CAs) and an increased risk for psychotic experiences (PEs), little is known about whether these associations vary across the life-course and whether mental disorders that emerge prior to PEs explain these associations.

METHOD

We assessed CAs, PEs and DSM-IV mental disorders in 23 998 adults in the WHO World Mental Health Surveys. Discrete-time survival analysis was used to investigate the associations between CAs and PEs, and the influence of mental disorders on these associations using multivariate logistic models.

RESULTS

Exposure to CAs was common, and those who experienced any CAs had increased odds of later PEs [odds ratio (OR) 2.3, 95% confidence interval (CI) 1.9-2.6]. CAs reflecting maladaptive family functioning (MFF), including abuse, neglect, and parent maladjustment, exhibited the strongest associations with PE onset in all life-course stages. Sexual abuse exhibited a strong association with PE onset during childhood (OR 8.5, 95% CI 3.6-20.2), whereas Other CA types were associated with PE onset in adolescence. Associations of other CAs with PEs disappeared in adolescence after adjustment for prior-onset mental disorders. The population attributable risk proportion (PARP) for PEs associated with all CAs was 31% (24% for MFF).

CONCLUSIONS

Exposure to CAs is associated with PE onset throughout the life-course, although sexual abuse is most strongly associated with childhood-onset PEs. The presence of mental disorders prior to the onset of PEs does not fully explain these associations. The large PARPs suggest that preventing CAs could lead to a meaningful reduction in PEs in the population.

Cytomegalovirus seropositivity and serointensity are associated with hippocampal volume and verbal memory in schizophrenia and bipolar disorder

INTRODUCTION

Cytomegalovirus (CMV) is a member of the herpesviridae family that has a limbic and temporal gray matter tropism. It is usually latent in humans but has been associated with schizophrenia, bipolar disorder and cognitive deficits in some populations. Hippocampal decreased volume and dysfunction play a critical role in these cognitive deficits. We hypothesized that CMV seropositivity and serointensity would be associated with hippocampal volume and cognitive functioning in patients with schizophrenia or bipolar disorder.

METHODS

102 healthy controls, 118 patients with bipolar disorder and 69 patients with schizophrenia performed the California Verbal Learning Test (CVLT) and had blood samples drawn to assess CMV IgG levels. A subgroup of 52 healthy controls, 31 patients with bipolar disorder and 27 patients with schizophrenia underwent T1 MRI for hippocampal volumetry. We analyzed the association between CMV serointensity and seropositivity with hippocampal volume. We also explored the correlation between CMV serointensity and seropositivity and CVLT scores.

RESULTS

In both patient groups but not in controls, higher CMV serointensity was significantly associated with smaller right hippocampal volume. Further, in the group of patients with schizophrenia but not bipolar disorder, CMV serointensity was negatively correlated with CVLT scores.

CONCLUSION

CMV IgG titers are associated with decreased hippocampal volume and poorer episodic verbal memory in patients with schizophrenia or bipolar disorder. The mechanism of this association warrants further exploration.

Embarrassment when illness strikes a close relative: a World Mental Health Survey Consortium Multi-Site Study

BACKGROUND

In this global study we sought to estimate the degree to which a family member might feel embarrassed when a close relative is suffering from an alcohol, drug, or mental health condition (ADMC) versus a general medical condition (GMC). To date, most studies have considered embarrassment and stigma in society and internalized by the afflicted individual but have not assessed family embarrassment in a large-scale study.

METHOD

In 16 sites of the World Mental Health Surveys (WMHS), standardized assessments were completed including items on family embarrassment. Site matching was used to constrain local socially shared determinants of stigma-related feelings, enabling a conditional logistic regression model that estimates the embarrassment close relatives may hold in relation to family members affected by an ADMC, a GMC, or both conditions.

RESULTS

There was a statistically robust association such that subgroups with an ADMC-affected relative were more likely to feel embarrassed compared to subgroups with a relative affected by a GMC (p<0.001), even with covariate adjustments for age and sex.

CONCLUSIONS

. The pattern of evidence from this research is consistent with conceptual models for interventions that target individual- and family-level stigma-related feelings of embarrassment as possible obstacles to effective early intervention and treatment for an ADMC. Macro-level interventions are under way but micro-level interventions may also be required among family members, along with care for each person with an ADMC.

Implications of modifying the duration requirement of generalized anxiety disorder in developed and developing countries

BACKGROUND

A number of western studies have suggested that the 6-month duration requirement of generalized anxiety disorder (GAD) does not represent a critical threshold in terms of onset, course, or risk factors of the disorder. No study has examined the consequences of modifying the duration requirement across a wide range of correlates in both developed and developing countries.

METHOD

Population surveys were carried out in seven developing and 10 developed countries using the WHO Composite International Diagnostic Interview (total sample=85,052). Prevalence and correlates of GAD were compared across mutually exclusive GAD subgroups defined by different minimum duration criteria.

RESULTS

Lifetime prevalence estimates for GAD lasting 1 month, 3 months, 6 months and 12 months were 7.5%, 5.2%, 4.1% and 3.0% for developed countries and 2.7%, 1.8%, 1.5% and 1.2% for developing countries, respectively. There was little difference between GAD of 6 months' duration and GAD of shorter durations (1-2 months, 3-5 months) in age of onset, symptom severity or persistence, co-morbidity or impairment. GAD lasting >or=12 months was the most severe, persistently symptomatic and impaired subgroup.

CONCLUSIONS

In both developed and developing countries, the clinical profile of GAD is similar regardless of duration. The DSM-IV 6-month duration criterion excludes a large number of individuals who present with shorter generalized anxiety episodes which may be recurrent, impairing and contributory to treatment-seeking. Future iterations of the DSM and ICD should consider modifying the 6-month duration criterion so as to better capture the diversity of clinically salient anxiety presentations.

Lithium: poisonings and suicide prevention

This study concerns 81 cases of lithium poisoning and shows that deliberate intoxications are prevalent during the first 3 years of lithium treatment as well as in cases with a previous history of suicide attempt. Therapeutic intoxications could generally be avoided by education concerning hygiene and diet and careful monitoring in cases of intercurrent diseases.

Social phobia: diagnosis and epidemiology, neurobiology and pharmacology, comorbidity and treatment

Social phobia is a common disorder associated with significant psychosocial impairment, representing a substantial public health problem largely determined by the high prevalence, and the lifelong chronicity. Social phobia starts in early childhood or adolescence and is often comorbid with depression, other anxiety disorders, alcohol and substance abuse or eating disorders. This cascade of comorbidity, usually secondary to social phobia, increases the disability associated with the condition. The possibility that social phobia may be a trigger for later developing comorbid disorders directs attention to the need for early effective treatment as a preventive measure. The most recent drug class to be investigated for the psychopharmacological treatment of social phobia is the SSRI group for which there is growing support. The other drug classes that have been evaluated are monoamine oxidase inhibitors (MAOIs), benzodiazepines, and beta-blockers. The SSRIs represent a new and attractive therapeutic choice for patients with generalized social phobia. Recently the first, large scale, placebo-controlled study to assess the efficacy of drug treatment in generalized social phobia has been completed with paroxetine. Paroxetine was more effective in reducing the symptoms than placebo and was well tolerated. Many now regard SSRIs as the drugs of choice in social phobia because of their effectiveness and because they avoid the problems of treatment with benzodiazepines or classical MAOIs.

[Mental disorders and migraine: epidemiologic studies]

Epidemiologic studies in the general population, taking into account certain bias inherent to the clinical observation have confirmed the clinical impression reporting a higher psychiatric comorbidity with persons suffering from migraine than in persons without migraine. Persons with migraine are at increased risk for affective and anxiety disorders, personality traits disorders (neuroticism), suicide attempts, but not for alcohol or illicit drug abuse. The comorbidity is more important in migraine with aura than in migraine without aura. Concerning affective disorders, the lifetime prevalence of major depression is 34.4% in persons with migraine and 10.4% in persons without migraine. For bipolar I disorder, prevalence is 6.8% in migraine with aura versus 0.9% when no migraine. Compared to no migraine, the lifetime prevalence of anxiety disorders in migraine is significantly increased in: panic disorder (10.9% vs 1.8%); generalized anxiety disorder (10.2% vs 1.9%); obsessive-compulsive disorder (8.6% vs 1.8%); phobic disorder (39.8% vs 20.6%). In addition, no psychopathological, biological or genetic explanation seems to be meaningful for the comprehension of this comorbidity pattern. These results remain primarily descriptive but they justify a clinical investigation of affective and anxiety disorders, and suicide attempts, in all person with migraine, and it also justifies the treatment of pain associated with the treatment of eventual affective or anxiety disorders.

[Pharmacotherapy in personality disorders: methodological issues and results]

The pharmacotherapy of personality disorders is less developed than are psychological treatments in this area, but they are a logical prolongation of psychobiological models of personality and temperament, and respond to the need of many clinicians in front of difficult patients. The assessment of drugs effects in personality disorders includes some important conceptual and methodological issues. Categorical or dimensional instruments evaluating baseline personality and under-treatment changes are now available. Such studies are necessary of long duration, with difficult patients, and use specific outcome criteria. The results obtained in the field of pharmacotherapy of personality disorders can be classified according to DSM IV axis-II categorization. In anxious personalities (cluster C), some isolated studies suggest a favourable effect of antidepressants on obsessive-compulsive dimension, on avoidant personality disorder, and on inhibition and trait-anxiety, especially when serotoninergic agents are used. Few studies have been conducted in cluster A personality disorders, and some are in favour of the interest of low doses of antipsychotic drugs in this group. Most studies have been conducted in cluster B, and especially in antisocial and borderline personality disorders. Partial positive results have been obtained using various classes of drugs for dealing with aggression and impulsive behaviors, including lithium, beta-blockers, carbamazepine, valproate, antipsychotic drugs, and also SSRIs. Self-harm and suicidal behaviors seem to be partially but significantly improved by antidepressants and low doses of antipsychotics. Opioid antagonisms may be helpful for these indications in the future. Other symptom-oriented strategies for psychopharmacology have been conceptualized, focused on depressive personality, emotional lability, cognitive and perceptual disturbances, or interpersonal sensitivity. Overall, the pharmacotherapy of personality disorder remains to date one of the less explored in psychiatry research. Nevertheless, it may lead in the future to the development of effective treatments, in complement to psychotherapy, for actually severe, chronic, and disabling disorder.

Anxiety and depressive disorders in fathers and mothers of anxious school-refusing children

OBJECTIVE

To examine anxiety and depressive disorders in the mothers and fathers of children with anxious school refusal and to test for the existence of differences in familial aggregation between children suffering from school refusal related to separation anxiety disorder and those suffering from phobic disorder-based school refusal.

METHOD

Using a blind standardized diagnostic evaluation (Schedule for Affective Disorders and Schizophrenia-Lifetime version, modified for the study of anxiety disorders; Diagnostic Interview for Genetic Studies; and Schedule for Affective Disorders and Schizophrenia for School-Age Children), the authors compared parental lifetime psychiatric illness for the 2 groups of anxious school refusers.

RESULTS

Relationships between specific anxiety disorders in children and their parents revealed increased prevalence of simple phobia and simple and/or social phobia among the fathers and mothers of phobic school refusers, and increased prevalence of panic disorder and panic disorder and/or agoraphobia among the fathers and mothers of school refusers with separation anxiety disorder. Simple and/or social phobia in the father, simple phobia in the mother, and age of the father were associated with the group of phobic school refusers.

CONCLUSIONS

The data show the high prevalence of both anxiety and depressive disorders in fathers and mothers of anxious school refusers. Significant differences were observed in familial aggregation considering the subgroups of anxious school-refusing children.

[Anxiolytics and hypnotics use by psychiatric inpatients' children: preliminary study]

Psychotropic drugs are widely used in adulthood in France, and few studies have yet been made concerning children. Literature studies have shown an important consumption on their part, increasing with age and especially for girls. Certain family factors which may prove to determine such use have been pointed out like family habits of toxique use, maternal depression, mother's occupation and family troubles. This consumption also seems related to psychiatric symptomatology in children together with previous use in childhood. This feasibility study will attempt to research the forms of anxiolytics and hypnotics use by children aged 6 to 16, one parent being a psychiatric in-patient. 51 in-patients of the university section have been included, corresponding to 74 children. The investigator look down socio-demographic date as well as anxiolytics and hypnotics use in a lifetime and that of antalgics for the week prior to the interview. The parents' depressive and anxious symptoms were measured by the HAD and the children's psychopathological symptoms by the CBCL. A phone contact was proposed to teenagers 13 to 16 years old. One patient only refused the interview, 7 patients left without filling in the questionnaire. The parents more often than not refused to establish contact with the teenager. Only 5 teenagers out of 22 could actually be interviewed. Whereas 94.1% of parents use psychotropic drugs, only 16.2% of children have used them throughout their lifetime. The consumption of these drugs is not related to age or sex but rather seems to be linked with the children's symptomatology. The development of this study should confirm these results on a wider scale through a different approach of teenagers.

Anxiolytic and hypnotic use in 376 psychiatric inpatients. GERMED Neuropsychotropics Group

This objectives of this study were three-fold: retrospectively evaluate anxiolytic/hypnotic consumption by psychiatric inpatients, identify the risk factors of prolonged intakes, and prospectively measure the impact of hospitalisation on the use of those drugs. Three hundred and seventy-six patients hospitalised in 11 psychiatric departments in the Paris region were studied using a structured interview for the anxiolytic/hypnotic treatments, DSM-III-R criteria, GHQ-12, HAD, Spiegel's questionnaire, COVI's anxiety scale and the CGI. Eighty-five per cent of the patients had taken one anxiolytic/hypnotic or more in the 3 months preceding hospitalisation. Hospitalisation induced little change in anxiolytic/hypnotic use: dosage frequency increased from 77% to 84% between the week preceding hospitalisation and that preceding discharge; 26% of consumers were taking at least two anxiolytics or two hypnotics in the first period vs. 23% in the second. The absence of withdrawal during hospitalisation was related to the high age and a diagnosis of depression rather than schizophrenia, to the existence of continuous intake over the 3 months preceding hospitalisation and to higher drug doses during the 7 days preceding hospitalisation. Prescription of treatment at the end of hospitalisation in previously non-user subjects was related to a higher HAD anxiety score at discharge.

Prevalence of suicide ideation and suicide attempts in nine countries

BACKGROUND

There are few cross-national comparisons of the rates of suicide ideation and attempts across diverse countries. Nine independently conducted epidemiological surveys using similar diagnostic assessment and criteria provided an opportunity to obtain that data.

METHODS

Suicide ideation and attempts were assessed on the Diagnostic Interview Schedule in over 40000 subjects drawn from the United States, Canada, Puerto Rico, France, West Germany, Lebanon, Taiwan, Korea and New Zealand.

RESULTS

The lifetime prevalence rates/100 for suicide ideation ranged from 2.09 (Beirut) to 18.51 (Christchurch, New Zealand). Lifetime prevalence rates/100 for suicide attempts ranged from 0.72 (Beirut) to 5.93 (Puerto Rico). Females as compared to males had only marginally higher rates of suicidal ideation in most countries, reaching a two-fold increase in Taiwan. Females as compared to males had more consistently higher rates for suicide attempts, reaching a two- to three-fold increase in most countries. Suicide ideation and attempts in most countries were associated with being currently divorced/separated as compared to currently married.

CONCLUSIONS

While the rates of suicide ideation varied widely by country, the rates of suicide attempts were more consistent across most countries. The variations were only partly explained by variation in rates of psychiatric disorders, divorce or separation among countries and are probably due to cultural features that we do not, as yet, understand.

Social phobia in general health care: an unrecognised undertreated disabling disorder

BACKGROUND

This study explored the prevalence of social phobia (SP) in general health care, sociodemographic characteristics of patients with SP, the age at onset and severity of SP, its comorbidity with other psychiatric disorders, and the recognition by general practitioners.

METHOD

The study was conducted in Paris as part of the WHO study on Psychological Problems in General Health Care. Among 2096 consecutive primary care patients, 405 were interviewed using the CIDI. DSM-III-R diagnoses, severity and disability were assessed.

RESULTS

The one-month prevalence of SP is high (4.9) in primary care, although underdiagnosed by GPs. It has an early onset and leads to substantial disability. Patients with SP are at risk of developing further depression, alcoholism or suicidal behaviour.

CONCLUSION

SP appears to be a true and frequently severe pathological condition. The awareness of GPs and the general population should be improved.

[Psychological trauma and mental disorders]

Fifty-eight female impatients consecutively hospitalized in the University Hospital Department of Psychiatry in Tours were interviewed with a clinician battery of instruments (among them, the SI-PTSD by Davidson). The diagnoses leading to hospitalization were: severe disorders of psychotic type (schizophrenic, schizophreniform, schizo-affective, schizoid and paranoid delusional disorders as well as bipolar disorder), borderline and narcissistic personalities for 7%, and other disorders for 53%. Among the results, we observed that 59% of these patients had experienced at least one major stressful event (rape 26%, other sexual assault 29%, physical assault 31%, seeing somebody dying in a violent way 8%, war scene 2%, injured in an accident 2%). As a consequence, 61% of the victims have suffered from PTSD and the diagnosis of PTSD was still present in 21%. In addition, in the victims, somatoform and dissociative disorders were significantly more frequent.

Recurrent brief depression: clinical and epidemiological issues

Initially based on empirical observations, the concept of RBD has led to operational diagnostic criteria allowing further studies in various and large populations. In line with the hypothesis of a continuum from normal sad mood to major depression, the spectrum of affective disorders is thus probably more in agreement with everyday clinical practice. Moreover, recurrent and so-called subthreshold conditions have been concurrently investigated in other fields of psychopathology. Nevertheless, many methodological problems and clinical implications of RBD still require further research. The question of a precise definition of the disorder, even if a consensus seems to be obtained about some key points, remains partially to be addressed, for example, concerning the problem of the reliability of assessment. The possibility of a seasonality of the episodes needs further investigations, as do the relationships between RBD and personality disorders such as borderline personality disorder. Finally, the important question of prophylactic treatment of RBD remains unsolved, as antidepressants have failed to demonstrate any efficacy and some neuroleptics have been proposed in particular conditions. Angst's prediction that clinical relevance, impairment, distress and public health impact of affective disorders could be related not only to the duration of an episode but also to the recurrence of episodes, possibly referring to a kindling model, has therefore been confirmed. His major contribution has been to underline, in various forms of affective disorders, the importance of conducting longitudinal clinical as well as epidemiologic studies to refine our psychopathological knowledge.

Subsyndromal ("mixed") anxiety--depression in primary care

OBJECTIVE

To determine in primary care settings the prevalence, clinical characteristics, and functional status of patients who have anxious and depressive symptoms who did not meet diagnostic criteria for major mood and anxiety diagnoses.

DESIGN

Patients were screened with the General Health Questionnaire and interviewed if they exceeded the cutoff score of 5. Also, one patient whose score was below the cutoff was interviewed for every two patients whose scores were above the cutoff.

SETTING

Five primary care sites in the United States, France, and Australia.

PATIENT

Two hundred sixty-seven patients presenting to their primary care physicians for general medical care and follow-up.

METHODS

Structured diagnostic interviews were conducted and ratings of anxiety, depression, and functional impairment were obtained by trained interviewers.

RESULTS

After adjustments for sampling, 5% of the patients had symptoms of anxiety, depression, and functional impairment, without meeting formal criteria for a major DSM-III-R mood or anxiety disorder. This was comparable to the prevalence of diagnosable DSM-III-R mood disorders but only one-fourth the prevalence of diagnosable anxiety disorders. These patients who had subsyndromal symptoms had rates of lifetime psychiatric disorders and prior psychiatric treatment comparable to those of patients meeting criteria for major mood and anxiety disorders.

CONCLUSION

The comparable rates of symptomatic distress, functional impairment, and prior psychiatric illness and treatment suggest that patients with subsyndromal anxiety and depressive symptoms warrant clinical recognition and possibly specific treatment.

The DSM-IV field trial for mixed anxiety-depression

OBJECTIVE

This field trial was designed to answer four questions. First, are patients presenting with anxious or depressed symptoms that are associated with significant impairment but do not meet DSM-III-R definitional thresholds for axis I anxiety or mood disorders? Second, is the impairment experienced by these patients simply the consequence of the severity of their medical conditions? Third, what percent of these patients present with depressive symptoms only, anxious symptoms only, and a mixture of both? Fourth, how should the operational criteria for the syndrome(s) presented by these patients be defined?

METHOD

A total of 666 patients from five primary care medical sites and two outpatient mental health sites were administered a semistructured psychiatric interview.

RESULTS

Patients presenting with affective symptoms that did not meet definitional thresholds for DSM-III-R axis I disorders were at least as common as patients with several of the already established anxiety and mood disorders in each of the seven sites, and their disorders were associated with significant distress or impairment. A nonspecific pattern of anxious and depressed symptoms was the modal presentation among these patients with currently subdefinitional threshold disorders, and they could be significantly differentiated in terms of current symptoms from patients presenting with a principal diagnosis of generalized anxiety disorder, major depressive episode, or panic disorder with agoraphobia.

CONCLUSIONS

The authors recommend that a mixed anxiety-depression category be included in the DSM-IV appendix for proposed diagnostic categories that need further study. A criteria set is proposed.

Prevalence of recurrent brief depression in primary care

Descriptions of mentally ill inpatients have strongly influenced current classifications of mental disorders. Primary care patients may therefore present a substantially different pathology. Some diagnoses, infrequent in psychiatric settings but common in the general population or in primary care, have been described, such as the concept of recurrent brief depression (RBD) proposed by Jules Angst. RBD refers to frequent but short-lasting (usually only a few days) severe depressive episodes. In parallel with a study organized by the World Health Organization aimed at defining the psychological disorders encountered in primary care, we investigated the prevalence of RBD, its severity, and comorbidity with major and well-defined disorders using a structured interview (CIDI). The current prevalence of RBD in a general practice population was found to be about 10%. The average duration of the episodes is 3-4 days. Ours results confirm the severity of this disorder; in particular, a history of suicide attempts is frequent (23.3%). Among RBD patients, 26% do not present any other psychiatric disorder. When a comorbidity is reported, depressive episodes (lasting at least two weeks, according to ICD-10) and generalized anxiety disorder are the main associated disorders. Our results are in favor of the existence of RBD as a separate and original nosological entity.

[Treatment of post-traumatic stress syndrome]

This paper reviews different psychotherapeutic and drug treatments for Post Traumatic Stress Disorder (PTSD). Psychotherapeutic treatments have changed from the abreaction technique to more classical psychodynamic approaches and recently to cognitive and behavioral techniques. Many drugs have been used in the treatment of PTSD but most of the studies were not controlled and included very few patients. More recently, double blind controlled studies have been performed comparing imipramine, desipramine, amitriptyline, phenelzine and placebo. A global efficacy has been found but the improvement was more closely related to associated symptoms, namely anxiety and depression, than to the core symptoms of PTSD.

Panic disorder in cardiac outpatients

OBJECTIVE

Continuing the long history of interest in the relation of anxiety disorders to cardiovascular function and symptoms, this study investigated the level of anxiety and prevalence of panic disorder in cardiac patients and the possible associations between specific abnormal ECG results and a diagnosis of panic disorder.

METHOD

Consecutive patients referred for ambulatory ECG recordings were assessed with the seven anxiety items of the Hospital Anxiety and Depression Scale. Then, 50 patients with scores higher than 8 (the anxious group) were interviewed with the Schedule for Affective Disorders and Schizophrenia--Lifetime Version Modified for the Study of Anxiety Disorders (SADS-LA).

RESULTS

Of the 50 anxious patients (26 male and 24 female) interviewed with the SADS-LA, 62% (N = 31) met the DSM-III-R criteria for panic disorder. Patients with panic disorder had a higher mean maximal heart rate and a shorter P-R interval than patients without panic disorder. Unlike the patients without panic disorder, the patients with panic disorder showed no correlation between maximal heart rate and minimal P-R interval.

CONCLUSIONS

The rate of panic disorder was high in the patients referred for ECG. Moreover, the prevalence of panic disorder was similar in the patients with and without ECG abnormalities, indicating that in anxious patients the presence of panic disorder does not rule out organic cardiac disease. On the other hand, the higher maximal heart rate and shorter P-R interval of the panic patients may be attributable to hypersensitivity of beta-adrenergic receptors in panic disorder.

Suicide attempts in patients with panic disorder

In a clinical sample of 100 outpatients with panic disorder, 42% had a history of suicide attempt. Female sex and being single, divorced, or widowed were associated with an increased risk of suicide attempt. Thirty-one (73.8%) of the suicide attempts occurred after the first panic attack and 27 (64.3%) after the onset of panic disorder. Eighty-eight of these patients met DSM-III-R criteria for at least one other diagnosis in addition to panic disorder. Moreover, 52% had a history of major depressive episode and 31% had a lifetime diagnosis of alcohol and/or other substance abuse. Compared with those who did not attempt suicide, those who attempted suicide were significantly more likely to have suffered from major depressive episode and alcohol or other substance abuse in their lifetime. Among the 35 patients with no comorbidity with either major depression or addictive behaviors, 17.1% had a history of suicide attempt. All had suffered from depressive symptoms and/or a personality disorder. The same association was found in four of 19 patients suffering from panic disorder only with or without agoraphobia.

[Panic disorder and alcoholism]

Relationships between alcoholism and anxiety disorder are well known by clinicians. Studies have recently shown that the prevalence of alcohol abuse or dependence is very high in patients with panic disorder with or without agoraphobia (Thyer et al., 1986; Bibb and Chambless, 1986). The aims of this study were to determine the prevalence and comorbidity of alcohol abuse and dependence in a population of panic outpatients who were consecutive referrals for treatment of panic disorder (PD) in an anxiety clinic. Patients were interviewed with the Schedule for Affective Disorders and Schizophrenia-Lifetime Version Modified for the study of anxiety disorders (SADS-LA) which is a standardized and semi-structured interview allowing to make diagnoses according to RDC, DSM III and DSM III-R criteria. One hundred and three panic patients (39 males and 64 females) were included in the study. Their mean age was 38.5 years (SD: 11.6). In this sample, 24.3% met the DSM III-R criteria for alcohol abuse and 8.7% those for alcohol dependence. Among these patients, 26.2%, abused of benzodiazepines and 16.5% of them of other substances. We found a high comorbidity rate. In fact, 6.8% of the patients met diagnostic criteria for PD alone, 31.0% for one more diagnosis, 29.1% for two more and 33.0% for three or more besides PD. In this study, we found an association between alcohol abuse and the presence of a lifetime diagnosis of major depressive episode and/or other addictive behaviors. Otherwise, alcohol abuse did not occur more often in patients suffering from panic disorder associated with agoraphobia and/or social phobia.

Anxiety disorders in a French general psychiatric outpatient sample. Comparison between DSM-III and DSM-IIIR criteria

In a general psychiatric outpatient sample (n = 1271) gathered through a cross-national French survey, anxiety and somatoform syndromes were assessed according to DSM-III and DMS-III-revised criteria. Lifetime and one-month prevalence rates in this population are provided and the high level of comorbidity between the anxiety syndromes is noted. The patient symptom profiles for panic syndrome, simple attacks, agoraphobia and generalized anxiety are displayed. The conspicuous consequences of the modifications brought in by the Revision-anticipatory anxiety in panic syndrome, and restricted period criteria for generalized anxiety- are discussed, with the conclusion that more field study assessment is required before further revision.

[Obsessive compulsive disorder. Clinical and epidemiologic studies]

Until recently, Obsessive-Compulsive Disorder (OCD) was considered rare trouble with rather poor outcome. Currently progress in behavioral psychology, psychopharmacology and methodology of epidemiologic studies multiplying by 50 the traditional prevalence rates, give an impetus to the interest in this pathology. Recent clinical and epidemiologic data in OCD are reported in this paper. Multiple questions are evoked such as the issue of OCD homogeneity, the meaning of comorbidity with other psychological disorders: depression, panic attacks, schizophrenia, Gilles de la Tourette syndrome, the reality of OCD prevalence rate in general and psychiatric populations, the usefulness of classical demarcation between psychosis/neurosis in the treatment of OCD, and finally the search for a genetic diathesis and risk factors implicated in predisposition to OCD. A close relationship between clinical, epidemiologic and genetic approaches seems to be required in order to answer these questions and constitutes a first step prior to carrying on basic and applied research.

[Usefulness of self-assessment scales for anxiety and depression in internal medicine]

The rating scales and questionnaires of quantitative psychopathology constitute an aid for the resident physician in the recognition of depressive and anxiety disorders in medical wards. The specific interest of these scales is more in the symptomatic intensity than in the diagnosis. A structured questionnaire leading to a DSM-III diagnosis of mood disorders shows the differences of these two approaches. Analyses of the results of two new self-assessment scales for depression compared to those of a diagnostic instrument permit to appreciate the respective prevalence of mood disorders and the intensity of depressive symptomatology.

[Changes in urinary levels of MHPG, VMA and 5-HIAA and plasma tryptophan in post-partum blues. Initial results]

In post-partum depressive illness ("post-partum blue") we measured urinary MHPG, VMA, 5-HIAA and free and total Trp. VMA and especially MHPG reflect the brain noradrenaline metabolism. Trp is the precursor of 5-HT synthesis and 5-HIAA is the main urinary catabolite of 5-HT. The clinical evaluation consisted in self-evaluation scales: Pitt scale 1, 3 and 5 days after delivery, CESD scale of NIMH (depression) and BONIS scale (anxiety) at 6th day. Moreover a psychiatrist measured depression intensity on the MADRS scale and DSM III data. First results seem to indicate a decrease of free MHPG and VMA, an increase of 5-HIAA and no alteration of free and total Trp. These modifications could involve adrenergic and serotoninergic alterations in brain.
