[Psychiatric effects of cardiac surgery].

The authors report three cases of psychotic complications of cardiac surgery. A review is made from literature and an inventory of psychological and organic factors implicated in this pathology. These complications are still frequent (up to 50% for Braceland, and 70% for Rabiner and al.). For Blacher there is an almost universal "psychosis" in by-pass surgery and frequent "hidden psychosis" (they are ignored and denied both by the staff and the patient). They are caused by the emotional stress, intensive care unit syndrome, or personal vulnerability. The symbolism of the heart and the personality of the cardiac patient are also in cause. Neurologic accidents, hypoxy, embolisms, are now less frequent. The collaboration of a psychiatrist with the cardiologic staff is mandatory. With this collaboration not only psychiatric complications but also somatic morbidity and mortality would be reduced.

A naturalistic follow-up study of French-speaking opiate-maintained heroin-addicted patients: effect on biopsychosocial status.

The purpose of this study was to evaluate the impact of opiate maintenance pharmacotherapy (OMP) on the biopsychosocial status of opiate-addicted patients in a cultural environment (France) that is not favorable to OMP and where methadone is not available. Buprenorphine and laudanum (opium tincture), which, to our knowledge, has not been reported previously in the scientific literature for OMP, were used in this study of a group of 18 opioid-dependent subjects. At time of initiation of OMP, mean age was 33 years, sex ratio male: female was 14:4, average duration of drug use was 11.2 years. Six patients received laudanum p.o., 15 g daily; 12 patients received buprenorphine sublingual 2 to 4 mg daily. This group of patients was selected because of persistent relapse and impairment after an average of 5.7 drug-free-oriented treatments over a period of 6.8 years. Initial evaluation and follow-up were made by way of a 150-min semi-structured interview using the Lifetime Retrospective Evaluation Score Table (LREST) and the Addiction Severity Index (ASI). Results showed that body weight and scores for physical and psychological health, socioprofessional status, and family relationships improved significantly after 14 months of OMP. These results show that highly impaired opiate-addicted patients doing poorly in drug-free treatment can respond to OMP even though methadone is not available and the idea of OMP is not favored.

[Neurobiology and pharmacotherapy of social phobia].

Social phobia (also known as social anxiety disorder) is still not clearly understood. It was not established as an authentic psychiatric entity until the diagnostic nomenclature of the American Psychiatric Association DSM III in 1980. In recent years, increasing attention among researchers has contributed to provide important information about the genetic, familial and temperamental bases of social phobia and its neurochemical, neuroendocrinological and neuroanatomical substrates, which remain to be further investigated. Up to date, there have been several findings about the possible influence of variables, including particularly genetic, socio-familial and early temperamental (eg behavioral inhibition) factors that represent risk for the later development of social phobia. Clinical neurobiological studies, based on the use of exogenous compounds such as lactate, CO2, caffeine, epinephrine, flumazenil or cholecystokinin/pentagastrin to reproduce naturally occurring phobic anxiety, have shown that patients with social phobia appear to exhibit an intermediate sensitivity between patients with panic disorder and control subjects. No difference in the rate of panic attacks in response to lactate, low concentrations of CO2 (5%), epinephrine or flumazenil was observed between patients with social phobia and normal healthy subjects, both being less reactive compared to patients with panic disorder. However, patients with social phobia had similar anxiety reactions to high concentrations of CO2 (35%), caffeine or cholecystokinin/pentagastrin than those seen in patients with panic disorder, both being more intensive than in controls. Several lines of evidence suggest specific neurotransmitter system alterations in social phobia, especially with regard to the serotoninergic, noradrenergic and dopaminergic systems. Although no abnormality in platelet serotonin transporter density has been found, patients with social phobia appear to show an enhanced sensitivity of both post-synaptic 5HT1A and 5HT2 serotonin receptor subtypes, as reflected by increased anxiety and hormonal responses to serotoninergic probes. Platelet 5HT2 receptor density has also been reported to be positively correlated to symptom severity in patients with social phobia. During anticipation of public speaking, heart rate was elevated in patients with social phobia compared to controls. Norepinephrine response to the orthostatic challenge test or to the Valsalva maneuver was also greater in patients with social phobia. While normal beta-adrenergic receptor number was observed in lymphocytes, a blunted response of growth hormone to clonidine, an a2-adrenergic agonist, was reported. This suggests reduced post-synaptic a2-adrenergic receptor functioning related to norepinephrine overactivity in social phobia. Decreased cerebrospinal fluid levels of the dopamine metabolite homovanillic acid have also been observed. There are relatively few reports of involvement of the adrenal and thyroid functions in social phobia, and all that has been noted is that patients with social phobia show an exaggerated adrenocortical response to a psychological stressor. Recent advances in neuro-imaging have contributed to find low striatal dopamine D2 receptor binding or low dopamine transporter site density in patients with social phobia. They have also demonstrated the involvement of the cortico-limbic pathways, including the prefrontal cortex, hippocampus and amygdala, which show an increased activity in different experimental conditions. These brain regions have extensively been reported to play an important role in the cognitive appraisal in determining the significance of environmental stimuli, in the emotional and mnemonic integration of information, and in the expression of contextual fear-conditioned behaviors, which might be disrupted in the light of the phenomelogical aspects of social phobia. A substantial body of literature based on case reports, open and placebo-controlled trials, has now clearly examined the efficacy of major classes of psychotropic agents including monoamine oxidase inhibitors, beta-blockers, selective serotonin reuptake inhibitors and benzodiazepines in social phobia. Until recently, irreversible non-selective monoamine oxidase inhibitors, of which phenelzine was the most extensively evaluated, were considered as the most efficacious treatment in reducing the symptomatology associated with social phobia in 50-70% of cases after 4 to 6 weeks. However, side effects and dietary restrictions limit their use. This led to the development of reversible inhibitors of monoamine oxidase A, for which careful dietary monitoring is not required. Moclobemide has been the most widely studied but produced unconvincingly therapeutic effects on social phobic symptoms. To date, selective serotonin reuptake inhibitors may be considered as a reasonable first-line pharmacotherapy for social phobia. There is growing evidence for the efficacy of the selective serotonin reuptake inhibitors fluvoxamine, fluoxetine, citalopram, paroxetine and sertraline. They have beneficial effects with response rates ranging from 50 to 80% in social phobia. It has been recommended that the treatment period should be extended at least 6 months beyond the early improvement achieved within the first 4 to 6 weeks. The overall advantages include tolerability with a low risk of adverse events. The benzodiazepines clonazepam and alprazolam have also been proposed for the treatment of social phobia. Symptomatic relief occurred in 40 to 80% of the cases with a relatively rapid onset of action within the first two weeks. Untoward effects, discontinuation-related withdrawal symptoms and abuse or dependence liability constitute major concerns about the use of benzodiazepines, so they should be reserved for cases unresponsive to the safer medications cited above. Beta-blockers such as atenolol and propanolol have commonly been employed in performance anxiety, decreasing autonomic symptoms (eg, tachycardia, sweating and dry mouth). However, they are not effective in the generalized form of social phobia. Other pharmacologic alternatives seem helpful for the management of social phobia, including venlafaxine, gabapentin, bupropion, nefazodone or augmentation with buspirone. Preliminary studies point to promising effects of these agents. Larger controlled clinical trials are now needed to confirm their potential role in the treatment of social phobia.

[Evaluating the quality of life of 42 heart transplant patients and candidates: a cross-sectional study].

OBJECTIVE: Although evaluation of heart transplant candidates and recipients is usually based on objective clinical variables, self-assessment has been proved to be an important component of treatment evaluation. Quality of life is a multidimensional concept, a mix of objective and subjective measures, that could reflect the adjustment to the illness and its treatment. Few studies have reported on quality of life in heart transplantation candidates. This exploratory study, conducted in Bordeaux (France), was designed to assess both objectively and subjectively the quality of life in heart transplant candidates and recipients and to determine the relationships between subjective and objective variables. METHOD: The assessment was cross-sectional; 21 candidates evaluated at an average of 10 (Sd 21.4) months into the waiting period, were matched with 21 recipients at 29.5 months post operative. Subjective evaluation of the quality of life was self-assessed by the Tableau d'évaluation assistée de la qualité de la vie (TEAQV) and the Nottingham Health Profile (NHP). A semi structured psychiatric interview, and the NYHA (New York Heart Association) cardiac insufficiency score provided objective measurements. RESULTS: The NHP and TEAQV mean scores were not not significantly different between the two groups: candidates (C) and recipients (R) reported similar subjective data regarding positive quality of life experience. The objective data indicated significant disadvantages for the candidate group: the cardiac insufficiency score was worse in the candidates [(NYHA mean score: (C) = 2.7 Sd 0.56 vs (R) = 0.7 Sd 0.8, t de Student p < 0.01)] and the DSM III-R axis 1 diagnoses were more frequent in the candidates [(C) = 16/21 vs (R) = 9/21 Chi2 p < 0.05)]. There was a prevalence of adjustment disorders in the candidates. Significant correlations were found between NYHA and NHP mean scores (r = 0.6, p < 0.01) and NYHA and physical and psychological dimensions of the TEAQV (r = -0.65 and r = -0.55, p < 0.01) in the recipient group. In the candidate group, no correlation was found between these scores. CONCLUSION: In the recipient group, objective and subjective assessment showed greater concordance than in the candidate group. Despite more objective physical and moderate yet frequent psychiatric complications, the candidate group reported as positively as did the recipients upon the quality of their life experience. This could be the result of psychological adaptation to the stressful situation. These data were in accordance to several earlier reports. However, the literature has remained controversial upon the evaluation of the quality of life of the candidates. The results of this study, limited by some methodological bias (the small number of patients assessed), need to be confirmed in a prospective study.

[Addiction and personality].

Within the field of substance abuse, it is now widely admitted that the addictive personality does not exist. No one personality type is predisposed to addiction. The predisposition to drug dependence involves many different factors: psychological, social, familial, biological. None of these factors can be the sole determinant of drug dependence. Keeping that in mind, it is of interest to review the recent data on the relationship between personality traits or disorders and opiate and cocaine dependence. Using DSM and ICD categorical assessment, no single personality disorder emerged, instead a range of personality disorders has been evaluated in opiate and cocaine dependent subjects. Every type of personality disorders (PD) existed but cluster BPD were the most common (especially antisocial personality disorder in opiate addicts). However, it is noteworthy that a large minority to a majority of subjects did not display any king of PD. The implication of these results is that antisocial PD is probably over-diagnosed in drug dependence clinical settings. The studies reviewed failed to demonstrate that personality disorders were strong predictors of outcome in opiate or cocaine dependence. However, opiate dependent PD subjects entering treatment had more severe problems and lower retention rate than non PD subjects. But the amount of improvement was not significantly different between PD subjects and non PD subjects. This demonstrated that substance dependent PD patients could benefit from treatment whose intensity and duration must be adjusted. There is good support for the idea that Sensation Seeking trait is a vulnerability factor to substance abuse. But after dependence develops, sensation seeking is probably irrelevant to continued use of the drugs. This break between the psychopathology of vulnerability of substance abuse and the psychopathology of dependence raises the question of the existence of dramatically different factors involved in both phases of addiction.

[A survey of private practice psychiatrist's training and activity in activity in Aquitaine, France, in 1993].

UNLABELLED: This study was conducted to gather information regarding the current professional activities of French private practice psychiatrists. METHOD: A mail survey was carried out in an attempt to find more about the characteristics of the 380 private practice psychiatrists in Aquitaine (south west France) in 1993. Data are reported in terms of psychiatrist's characteristics (demographics, training and practice activities), patient characteristics and trends in treatment modalities. RESULTS: There was a good response rate (55%), and this enabled us to statistically analyze the data to determine profiles of activities. For the respondents in this survey, the median age is 45 years and 30.7% of respondents are women. The portion of responders reporting a qualification in Neuropsychiatry versus Psychiatry, is low (1/7). The patients seen in private practice are generally young females with anxiety and affective disorders. An important feature was the trend for psychotherapy training and practice. Psychoanalytically oriented and individual psychotherapy were predominant over other forms of psychotherapy. Half of the psychiatrists reported using pharmacotherapy in combination with psychotherapy. There are only little differences in the practice of young and female psychiatrists. CONCLUSION: The impact of psychodynamic theories on the training of French private practice psychiatrists is still very important. Interestingly, these same psychiatrists seem to use an eclectic approach to their practice of psychiatry; about half of the respondents report using pharmacological treatments in combination with psychoanalytically oriented psychotherapy.

[Quantitative evaluation of sharing practices of materials at risk for infectious virus contamination by intravenous opiate users seeking treatment--application of the RAB(Risk for AIDS Behavior) self-administered questionnaire].

The objective of this study was to quantify the occurrence of AIDS risk related sharing activities in i.v. opiate users seeking treatment using a self administered questionnaire. Subjects were recruited among first time consultants of an outpatient clinic and assessed using the Risk for AIDS Behavior questionnaire (RAB), a self administered questionnaire that assesses both needle-sharing and unprotected sexual activity; the Beck Depression Inventory (BDI) a self administered questionnaire that assesses depressive symptoms; and the Addiction Severity Index (ASI), a 45-min, structured interview that provides assessments of problem severity in seven functional areas commonly impaired among drug abusers. Among the 102 patients who came in for treatment, all 66 subjects reporting i.v. drug abuse agreed to participate. The study was based on the data collected from these 66 subjects of whom 49 were males (74%) and mean age +/- SD was 31 +/- 5. Fifty-eight-percent of theses subjects reported having shared needles or related paraphernalia over the past 6 months. Despite informational campaigns on the risks of sharing and despite the well spread knowledge of such a risk, most i.v. opiate users seeking treatment report having shared at least once over the previous 6 months.

[Lethal catatonia: clinical aspects and therapeutic intervention. A review of the literature].

Lethal catatonia continues to occur and represents a nonspecific syndrome associated with diverse organic as well as functional conditions. From this perspective, neuroleptic malignant syndrome may be conceptualized as a neuroleptic-induced toxic or iatrogenic form of organic lethal catatonia. Neuroleptics appear ineffective in the treatment of lethal catatonia and should be stopped whenever this disorder is suspected. Existing data suggest that ECT is a safe and effective treatment for lethal catatonia. ECT also appears effective in the treatment of neuroleptic malignant syndrome.

[Case study--relationship between prevalence of shyness, social phobia and avoidant personality in male sexual disorders].

UNLABELLED: Social phobia, avoidant personality disorder and shyness are very akin disorders, despite the fact that the first two are mental disorders, whereas the third is found mainly in lay or psychological literature. The relationship between these disorders and male sexual disorders can only be hypothesized from clinical studies and psychopathological theories. Social phobia, avoidant personality disorder, and shyness, share a probable indirect responsibility in sexual disorders because they impair the ability of subjects to meet partners. There are only a few direct studies of the negative impact of shyness on sexual behavior. OBJECTIVE: The objective of this study was to compare males with sexual disorders to non-sexual disorder males on diagnosis of social phobia, avoidant personality disorder and shyness. METHODS: We conducted a case-control study comparing a group of male patients seeking care for sexual disorders (n = 87) and a control group of male subjects without sexual disorder (n = 87), regarding the diagnosis of social phobia, avoidant personality disorder and shyness. Diagnoses were appreciated with a structured diagnostic interview (CIDI for the diagnosis of social phobia) or a list of criteria (DSM IV criteria for avoidant personality disorder) and through standardized scales (Fear Questionnaire, CBSHY, Cottraux male sexual problems questionnaire). Severity of shyness was evaluated through visual analog scales. RESULTS: We found strong significant statistical differences between cases and controls regarding the percentage in each group of social phobia, avoidant personality disorder and shyness. For shyness, the mean score at CBSHY was 16.2 (+/- 12.63) for the cases and 6.07 (+/- 6.67) for the controls (p < 0.0001), whereas the percentage of cases with a score of > 19.5 was 41.4% vs 6.9% for the controls (p < 0.001); 27.6% of the cases had a CIDI diagnosis of social phobia vs 8% of the controls (p < 0.001); 31% of the cases implemented DSM IV criteria for the diagnosis of avoidant personality disorder vs 6.9% of the cases (p < 0.001). CONCLUSION: Our results are in favor of one or several factors in common between social phobia, avoidant personality disorder and shyness, which would be strongly related to male sexual disorders.

[Anxiety disorders in private practice psychiatric out-patients: prevalence, comorbidity and burden (DELTA study)].

Few data are currently available on the prevalence and associated characteristics of anxiety disorders in psychiatric out-patients in France, in particular in the private health-care. However, this represents one of the principal systems of care for patients suffering from anxiety disorders, with a possible direct access and several types of treatments available (pharmacotherapy but also different kinds of psychotherapy). The aim of our study was to describe the prevalence of anxiety disorders in a large sample of patients consulting in the private sector, and in addition to study the comorbidity, the severity of the disorders, their consequences on quality of life and health care consumption. The studied patients were included and assessed by 501 psychiatrists from all the country, at the time of a first visit. Inclusions were to be made in a consecutive way, but with the exclusion of psychotic disorders and dementia. A sample of 1 955 patients was obtained, and all subjects had a standardized diagnostic assessment with the Mini International Neuropsychiatric Interview (MINI) and with various dimensional scales of symptomatology severity, quality of life, and health care consumption. On the whole, at least one current anxiety disorder was found in 64.3% of the patients, while 55% had a depressive disorder. Individually, the prevalence rates are 29.4% for generalized anxiety disorder, 25.9% for agoraphobia, 19.2% for panic disorder, 15.3% for social phobia, 11.4% for obsessive-compulsive disorder, and 5.4% for post-traumatic stress disorder (PTSD). A history of suicide attempts was found in 12-20% of patients, and an elevated suicide risk was found for example in 25% of PTSD patients. The scores of the symptomatic scales, adaptation and quality of life measure show a very significant anxious symptomatology, with serious functional consequences. Approximately 75% of patients had another medical consultation during the three previous months, and 9% have been hospitalized. An interruption of work was found in 25% of the patients during the last three months, in average for 35 days. Concerning drug consumption before the visit by anxiety disorders patients, the preponderance of anxiolytic use is notable (85 to 98% according to categories of anxiety disorders) when compared to that of antidepressants (20 to 40%). Moreover, 38.4% of the whole sample took an anxiolytic once a day for at least three months and about 40% of them had dependence symptoms. In conclusion, this study showed the quantitative importance of anxiety disorders among psychiatric out-patients in the private practice sector in France, all the categories of anxiety being represented, and the high level of severity and burden of these disorders. Compared to some data published before, the prevalence rates of these anxiety disorders seem to be increasing.
