ABSTRACT

OBJECTIVE: Body Dysmorphic Disorder (BDD) has replaced the old and ill-defined concept of dysmorphophobia since its introduction as a full-blown disorder in DSM-III-R in 1987. Since then, the body of knowledge on BDD has considerably increased. At the same time, cosmetic medicine and surgical procedures, for which the indications and outcomes of BDD should be taken into account, have become common. Hence, we decided to undertake a review of the literature on BDD aimed at French speaking practitioners. METHOD: We searched Medline for the literature on BDD and dysmorphophobia in English and in French and made a critical examination of findings resulting from those studies where the methodology was sound. RESULTS: BDD is frequent in the general population with a point prevalence between 1.7 and 2.4% and often severe. Delusive and non-delusive forms of BDD likely belong to the same entity and both respond to the same treatment. Serotonin reuptake inhibitors and cognitive behavioral therapies have demonstrated their efficacy in randomized controlled studies. Esthetic, medical and surgical treatments, which are very often sought after by BDD patients, have been shown to be ineffective and potentially harmful. DISCUSSION: Our review confirms the progress in knowledge on BDD. The most interesting results concern clinical characteristics, epidemiology in the general population, and treatment. The prevalence of BDD in the general population should prompt every practitioner to take this disorder into account when faced with the increasing demand for medical and surgical cosmetic procedures. Nevertheless, further research is needed, particularly on the demand of non psychiatric treatments by BDD patients and the way medical or surgical specialists manage it.

ABSTRACT

BACKGROUND: The aim of this study was to investigate the relationship between the levels of insight and checking-related uncertainty in patients with obsessive-compulsive disorder (OCD). SAMPLING AND METHODS: Twenty OCD patients with checking compulsions and without current comorbidity were recruited. We used an experimental paradigm that gave subjects the opportunity to check during a decision-making task, thereby allowing for the calculation of a response time index (RTI) as the 'uncertainty cost' during decision-making. The level of insight was assessed with the Brown Assessment of Beliefs Scale (BABS). RESULTS: Regression analyses indicated a significant positive correlation between RTI and BABS scores (r = 0.49). CONCLUSIONS: The level of insight is related to cognitive characteristics underlying OCD symptoms, in particular, checking-related uncertainty in checking OCD patients. STUDY LIMITATIONS: The absence of a comparison group and the low number of included patients are the main limitations of the present study.

ABSTRACT

BACKGROUND: Behavioral inhibition (BI), a heritable temperament, predisposes one to an increased risk of social phobia. Recent investigations have reported that BI may also be a precursor to anxiety as well as depressive and alcohol-related disorders, which are frequently comorbid with social phobia. In the present study, we explored the relationship between BI and psychiatric disorders in 256 adults with a primary diagnosis of social phobia. METHODS: BI severity was retrospectively assessed with the Retrospective Self-Report of Inhibition (RSRI). The severity of social phobia and the presence of comorbid diagnoses were evaluated with the Liebowitz Social Anxiety Scale (LSAS) and the Mini-International Neuropsychiatric Interview, respectively. RESULTS: The RSRI score was significantly and positively correlated with both the LSAS score and the occurrence of a major depressive disorder. No significant association was found with other anxiety and substance-related disorders. LIMITATION: The assessment of BI was retrospective and self-reported. CONCLUSION: A childhood history of BI was associated with an increased risk of depressive comorbidity in social phobia.

ABSTRACT

OBJECTIVE: To determine the most appropriate cutoff value for the Sexual Interest and Desire Inventory-Female (SIDI-F) score to discriminate between women with hypoactive sexual desire disorder (HSDD) and those with no female sexual dysfunction (FSD). The SIDI-F is a clinician-rated instrument consisting of 13 items designed to assess HSDD severity in women. The total score ranges from 0 to 51, with higher scores indicating better sexual function. METHODS: Data from patients enrolled in a North American nontreatment study and a European nontreatment study were analyzed. Both studies were 4-week, prospective, multicenter trials designed to assess the reliability and validity of the SIDI-F. Only patients with HSDD or no FSD were included in this analysis. Receiver operating characteristics (ROC) analysis was used to determine the ability of the SIDI-F to differentiate between patients with HSDD and those with no FSD at baseline. RESULTS: A total of 428 women were included in this analysis: 174 from North America (HSDD 113, no FSD 61) and 254 from Europe (HSDD 130, no FSD 124). In the North American study, a SIDI-F cutoff score of 33 minimized the difference between sensitivity (94.7%) and specificity (93.4%). In the European study, SIDI-F cutoff scores of both 33 and 34 minimized the difference between sensitivity (95.2%) and specificity (94.4%). CONCLUSIONS: In appropriately screened women, a SIDI-F score of ≤33 indicates the presence of HSDD.

ABSTRACT

OBJECTIVES: To evaluate the effect of cosmetic surgery in patients with a minimal defect in appearance, with and without body dysmorphic disorder (BDD), 5 years after their request for plastic surgery. METHODS: Thirty patients requesting cosmetic surgery with a minimal defect in appearance, 12 diagnosed with BDD and 18 not, were contacted 5 years later for a telephone interview about their cosmetic surgery, their satisfaction with it, BDD diagnosis, handicap, and psychiatric comorbidity. RESULTS: Of the 30 patients, we were able to re-evaluate 24 subjects (80%), 10 with BDD and 14 without. Seven BDD subjects had undergone cosmetic surgery compared with 8 without BDD. Patient satisfaction with the intervention was high in both groups. Nevertheless at follow-up, 6 of the 7 BDD patients who had surgery still had a BDD diagnosis and showed higher levels of handicap and psychiatric comorbidity than their non-BDD counterparts. Moreover, 3 non-BDD patients had developed BDD at follow-up. DISCUSSION: The high level of satisfaction with their surgery expressed by BDD patients was surprising and in contrast to the literature. It may explain, together with the patients' strong insistence, why plastic surgeons do not fully agree with psychiatrists on the contraindication of plastic surgery for BDD patients. Nevertheless in our study, most of the BDD patients were still diagnosed with BDD 5 years after surgery, with a significant handicap. The BDD diagnosis at follow-up in patients initially without BDD might be related to the presence of sub-threshold symptoms at the initial evaluation. CONCLUSION: This prospective study confirms that cosmetic surgery is not effective against BDD despite patients' reported satisfaction. Cosmetic surgery had no significant effects on BDD diagnosis, handicap or psychiatric comorbidity in BDD patients 5 years after surgery. Furthermore, BDD appeared at follow-up in some subjects not initially diagnosed. Patients' reported satisfaction with surgery may help explain why some plastic surgeons do not consider BDD a complete contraindication to cosmetic surgery.

ABSTRACT

Volumetric magnetic resonance imaging (MRI) studies in obsessive-compulsive disorder (OCD) have reported a smaller volume of the orbitofrontal cortex (OFC) and a larger volume of the thalamus compared with healthy controls. Both of these brain regions are strongly connected; therefore, it may be hypothesized that cortical and thalamic alterations are related. Here, we investigated the relationship between thalamic and orbitofrontal volumes in OCD patients relative to healthy controls. MRI volumetric measurements of the thalamus and the OFC were obtained in 16 OCD patients without comorbidity and 16 comparison subjects matched for age, sex and educational level. Partial correlation analyses that controlled for intracranial volume (ICV) were performed to explore relationships between thalamic and OFC volumes in each group. In order to assess the specificity of this relationship, we conducted similar analyses of the anterior cingulate cortex (ACC) as a non-OFC cortical volume. Finally, by using data from previously published volumetric MRI studies, we conducted a meta-regression to explore the relationships between volume changes in these regions of interest. Results showed that thalamic volumes were significantly negatively correlated with OFC volumes in OCD patients (r=-0.83, p<0.001), but not in healthy subjects (r=-0.15, p=0.59). A significant relationship between thalamic and ACC volumes was found neither in the OCD patients (r=0.03, p=0.91) nor in the comparison subjects (r=-0.23, p=0.40). Furthermore, meta-regression analyses showed that previously reported volume changes in the thalamus were significantly correlated with OFC volume changes (r=-0.71, p<0.05), but not with ACC volume changes (r=0.07, p=0.86). Although our results do not allow for any causal relationship to be established, they suggest that structural alterations of both the thalamus and the OFC are inversely and specifically related in OCD.

ABSTRACT

The ventral striatum, including the head of the caudate nucleus and the nucleus accumbens, is a putative target for deep brain stimulation (DBS) in the treatment of obsessive-compulsive disorder (OCD) and major depression (MD). However, the respective roles of these structures in the pathophysiology of OCD and MD remain to be clarified. To address this issue, DBS of the ventral striatum was tested in 2 patients with severely distressing and intractable forms of OCD and MD. Comparisons of clinical outcomes and anatomical data on electrode positioning showed that caudate nucleus stimulation preferentially alleviated OCD manifestations, whereas nucleus accumbens stimulation improved depressive symptoms. These findings suggest that the caudate nucleus and nucleus accumbens participate differently in the pathogenesis of both of these psychiatric conditions.

ABSTRACT

BACKGROUND: Many neuroimaging studies exploring the volumes of brain structures in obsessive-compulsive disorder (OCD) have been published in the past 2 decades. In this study, we attempted to provide a complete overview of structural alterations in OCD by meta-analyzing magnetic resonance imaging (MRI) data. METHODS: We conducted a systematic search of MRI studies that reported volumetric measurements in both OCD patients and healthy subjects. Data were entered into the meta-analysis through calculation of the standardized mean differences (SMDs) between the volumes of cerebral regions in OCD patients and the corresponding volumes in control subjects. We then performed a meta-regression to explore the influence of clinical covariates on effect sizes. RESULTS: Although no volumetric differences were found for the whole brain, intracranial region, gray matter, or prefrontal cortex, OCD patients did show a reduced volume of the left anterior cingulate cortex (ACC) and the left and right orbitofrontal cortex (OFC). No significant volumetric differences within the basal ganglia were observed, although the left and right thalamic volumes were significantly increased in OCD patients. The severity of obsessive or compulsive symptoms correlated significantly with the effect sizes for the left and right thalamus. CONCLUSIONS: Our findings indicate volumetric differences between OCD patients and control subjects in the cortical and thalamic regions, suggesting that structural alteration of the thalamocortical pathways may contribute to the functional disruptions of frontosubcortical circuits observed in OCD.

ABSTRACT

OBJECTIVE: Recent functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) studies based on the symptom provocation paradigm have explored neural correlates of the cognitive and emotional processes associated with the emergence of obsessive-compulsive disorder (OCD) symptoms. Although most studies showed the involvement of cortico-subcortical loops originating in the orbitofrontal cortex and the anterior cingulate cortex, an increased activity within numerous other regions of the brain has inconsistently been reported across studies. To provide a quantitative estimation of the cerebral activation patterns related to the performance of the symptom provocation task by OCD patients, we conducted a voxel-based meta-analysis. METHODS: We searched the PubMed and MEDLINE databases for studies that used fMRI and PET and that were based on the symptom provocation paradigm. We entered data into a paradigm-driven activation likelihood estimation meta-analysis. RESULTS: We found significant likelihoods of activation in cortical and subcortical regions of the orbitofrontal and anterior cingulate loops. The left dorsal frontoparietal network, including the dorsolateral prefrontal cortex and precuneus, and the left superior temporal gyrus also demonstrated significant likelihoods of activation. CONCLUSION: Consistent results across functional neuroimaging studies suggest that the orbitofrontal and anterior cingulate cortices are involved in the mediation of obsessive-compulsive symptoms. Based on recent literature, we suggest that activations within the dorsal frontoparietal network might be related to patients' efforts to resist the obsessive processes induced by the provocation task. Further research should elucidate the specific neural correlates of the various cognitive and emotional functions altered in OCD.

ABSTRACT

BACKGROUND: Metabolic overactivity of corticosubcortical loops including the caudate nucleus (CN) has been reported in obsessive-compulsive disorder (OCD) using functional imaging techniques. However, direct proof of a modification of neuronal activity within the CN of OCD patients is still lacking. We tested the hypothesis that obsessions or compulsions might be associated with particular features of neuronal activity in the CN of OCD patients. METHODS: Single unit recordings were performed peroperatively in the CN of three patients with severe forms of obsessive-compulsive disorder (OCD) who were candidates for deep brain stimulation of the CN. Severity of obsessions was assessed preoperatively with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and peroperatively with a subjective obsession score based on a visual analog scale (VAS). RESULTS: Frequency of CN discharge and variability of interspike intervals were found to be abnormally high in two patients with a high VAS score during surgery but not in one with a low VAS score. Lateralization and depth of recording influenced neuronal activity variably among patients. CONCLUSIONS: Because the three patients had high Y-BOCS scores before surgery, these findings suggest that caudate hyperactivity in OCD is concomitant with the occurrence of the obsession process.

ABSTRACT

OBJECTIVES: To evaluate the effect of cosmetic surgery and the stability of body dysmorphic disorder (BDD) diagnosis in patients with a minimal defect in appearance, with and without BDD, 5 years after their request for plastic surgery. SUBJECTS AND METHODS: Thirty patients requesting cosmetic surgery with minimal defect in appearance, of whom 12 had BDD and 18 did not, were re-evaluated 5 years later by telephone interview regarding their cosmetic surgery interventions, satisfaction with the intervention, BDD diagnosis, handicap, and psychiatric comorbidity. RESULTS: Of the 30 patients, we were able to re-evaluate 24 subjects (80%), 10 with BDD and 14 non-BDD. Seven BDD subjects had undergone cosmetic surgery vs 8 non-BDD. Patient satisfaction with the intervention was high in both groups. Nevertheless at follow-up, 6 of the 7 operated BDD patients still had a BDD diagnosis and exhibited higher levels of handicap and psychiatric comorbidity compared to their non-BDD counterparts. Moreover, 3 non-BDD patients had developed a BDD at follow-up. CONCLUSION: This prospective study confirms that cosmetic surgery is not efficient on BDD despite declared patient satisfaction. Cosmetic surgery had no significant effects on BDD diagnosis, handicap or psychiatric comorbidity in BDD patients at 5-year follow-up. Furthermore, BDD appeared at follow-up in some initially non-BDD diagnosed subjects. Patients' declared satisfaction with surgery may contribute to explain why some plastic surgeons may not fully adhere to the contraindication of cosmetic surgery in BDD.

ABSTRACT

INTRODUCTION: Benzodiazepines are the most widely used psychotropic agents in the world. Abuse and dependence are reported in the general population and among drug misusers, including those dependent on heroine. Benzodiazepine use by heroine users increases their risk of overdose, not only from heroin but also substitution drugs such as methadone and more recently buprenorphine. Hence, detoxification from benzodiazepines is desirable. OBJECTIVE: The objective of this paper was to review the literature and determine the best benzodiazepine detoxification procedure for opiate-dependent individuals receiving substitution treatment. METHODS: Relevant studies were sought through systematic searches of Medline and Toxibase (a database focusing on substance abuse). RESULTS: There were fewer controlled studies than expected about benzodiazepine detoxification, and all of them excluded subjects who misused opiates or were in opiate substitution treatment. The best evidence supports a procedure where the patient is switched to a long-lasting benzodiazepine and the dose then tapered by 25% of the initial dose each week. Diazepam is the drug most often used in the framework. In opiate users, diazepam may raise special problems of misuse, as suggested by clinical and epidemiologic studies. Nonetheless, diazepam is the only benzodiazepine found to be effective for this withdrawal in controlled studies and some studies indicate that unprescribed diazepam use in heroin users is sometimes motivated by the desire to alleviate withdrawal symptoms and discomfort. CONCLUSION: Although diazepam appears to have potential for abuse, the available data does not rule out its therapeutic interest for benzodiazepine withdrawal in patients on opiate substitution treatment in an adequate treatment setting. Specific studies of this population are needed.

ABSTRACT

In a previous case-control study, we found marked differences between a group of patients with male sexual disorders and a control group without any sexual disorder regarding the percentage of social phobia (SP) in each group. On this basis, our aim in this study was to test the hypothesis that premature ejaculation (PE) as a specific sexual disorder and SP might be strongly related, by comparing subjects with PE to a control group without any sexual disorder regarding the diagnosis of SP. Subjects with PE were recruited at private practice sexology settings in France. Control subjects were recruited among inpatients in a surgical ward. Diagnosis of SP was made with the Composite International Diagnostic Interview. Diagnosis of PE was clinician-rated according to DSM-IV criteria. Eighty-five subjects with PE only were compared to 93 control subjects without any sexual disorder. Forty (47%) subjects with PE versus 8 (9%) controls were diagnosed with SP (chi(2)=3.35, df=1, P=.001). Logistical analysis showed that SP and PE were strongly associated (odds ratio=10.97, 95% CI=4.49-26.06; chi(2)=28.28, df=1, P=.0001). This study is the first to show a clear relationship between SP and PE. Although requiring confirmation by further studies, this finding has immediate clinical consequences given that SP and PE can be treated by the same medication, a selective serotonin-reuptake inhibitor (SSRI). Moreover, since SP is a likely risk factor for PE, this might argue for preventive action on both disorders in children.

ABSTRACT

The pathophysiology of obsessive-compulsive disorder (OCD) remains unknown. However, increasing attention has been paid to the putative role of the serotoninergic system, the strongest evidence being based on the widely demonstrated efficacy of serotonin (5HT) reuptake inhibitor antidepressants in the treatment of OCD. The therapeutic effects are correlated with changes in peripheral parameters of 5HT function, which have been found to be altered in OCD, suggesting the possibility of reduced 5HT reuptake capacity. This could reflect a compensatory mechanism presumably due to decreased availability of extracellular 5HT, as evidenced by data derived from direct assessment of central 5HT neurotransmission. The development of new neurochemical probes that explore the sensitivity of various 5HT receptor subtypes has provided precious information. m-Chlorophenylpyperazine (m-CPP), an agonist to 5HT1A, 5HT1D, and 5HT2C receptors, and which also blocks 5HT3 receptors, exacerbates OC symptoms. In contrast, neither MK-212 (6-chloro-2-[1-piperazinyl]-pyrazine), a 5HT1A and 5HT2C receptor agonist, nor ipsapirone or buspirone, which acts as an agonist to 5HT1A receptors, have any effect on OC symptom severity. This suggests the potential implication of the 5HT1D receptor, as shown by the aggravation of OC manifestations in response to sumatriptan, a selective 5HT1D receptor agonist. The 5HT3 plays no specific role, given the lack of influence of the 5HT3 antagonist ondansetron, on OC symptom intensity. Further studies are required to elucidate the pharmacological molecular determinants of the putative 5HT1D receptor dysfunction.

ABSTRACT

Obsessive-compulsive disorder (OCD) is an anxiety disorder associated with recurrent intrusive thoughts and repetitive behaviors. Although conventional pharmacological and/or psychological treatments are well established and effective in treating OCD, symptoms remain unchanged in up to 30% of patients. Deep brain stimulation (DBS) of the anterior limb of the internal capsule has recently been proposed as a possible therapeutic alternative in treatment-resistant OCD. In the present study, the authors tested the hypothesis that DBS of the ventral caudate nucleus might be effective in a patient with intractable severe OCD and concomitant major depression. Psychiatric assessment included the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Hamilton Depression Rating Scale (HDRS), the Hamilton Anxiety Rating Scale (HARS), and the Global Assessment of Functioning (GAF) Scale for determining the symptom severity of OCD, depression, and anxiety as well as the quality of pychosocial and occupational functioning, respectively. Neuropsychological assessment consisted of a wide range of tests primarily exploring memory and executive functions. Deep brain stimulation of the ventral caudate nucleus markedly improved symptoms of depression and anxiety until their remission, which was achieved at 6 months after the start of stimulation (HDRS < or = 7 and HARS < or = 10). Remission of OCD (Y-BOCS < 16) was also delayed after 12 or 15 months of DBS. The level of functioning pursuant to the GAF scale progressively increased during the 15-month follow-up period. No neuropsychological deterioration was observed, indicating that DBS of the ventral caudate nucleus could be a promising strategy in the treatment of refractory cases of both OCD and major depression.

ABSTRACT

Erectile dysfunction (ED) and depression are highly prevalent and frequently comorbid. Sildenafil effectively treats ED in men with depression and in men taking antidepressants. We evaluated the efficacy of sildenafil in men with depression in remission and ED. Patients with a history of ED when major depressive disorder (MDD) was diagnosed, which persisted after MDD was treated to remission, were randomized to 12 weeks of treatment with sildenafil (50 mg, flexible) or placebo. Efficacy was assessed using intercourse success rates, a global efficacy question (Has treatment improved your erections?), the International Index of Erectile Function (IIEF) and Life Satisfaction Checklist (LSC). By week 12, intercourse success rates were significantly higher among sildenafil- (74%) compared to placebo-treated patients (29%; P=0.0001). About 83% and 34% of sildenafil- and placebo-treated patients, respectively, reported improved erections (odds ratio=9.4, P=0.0001). IIEF scores in the sildenafil group (n=83) were significantly improved compared to those in the placebo group (n=85; P <0.0001). LSC sexual life item improved significantly among sildenafil- versus placebo-treated patients. The most frequently reported adverse events were transient and mild-to-moderate. Sildenafil is an effective and well-tolerated treatment for ED in patients with a history of ED at the time of MDD diagnosis, and which persisted after the MDD was treated to remission.

ABSTRACT

In most European countries, methadone treatment is provided to only 20-30% of opiate abusers who need treatment due to regulations and concerns about safety. To address this need in France, all registered medical doctors since 1995 have been allowed to prescribe buprenorphine (BUP) without any special education or licensing. This led to treating approximately 65,000 patients per year with BUP, about ten times more than with more restrictive methadone policies. French physician compensation mechanisms, pharmacy services, and medical insurance funding all minimized barriers to BUP treatment. About 20% of all physicians in France are using BUP to treat about half of the estimated 150,000 problem heroin users. Daily supervised dosing by a pharmacist for the first six months resulted in significantly better treatment retention (80% vs 46%) and lower heroin use. Intravenous diversion of BUP may occur in up to 20% of BUP patients and has led to various infections and relatively rare overdoses in combination with sedatives. Opiate overdose deaths have declined substantially (by 79%) since BUP was introduced in 1995. Newborn opiate withdrawal in mothers treated with buprenorphine compared to methadone was reported to be less frequent, less severe, and of shorter duration. Although some of the public health benefits seen during the time of buprenorphine expansion in France might be contingent upon characteristics of the French health and social services system, the French model raises questions about the value of tight regulations on prescribing BUP imposed by many countries throughout the world.
