Beyond splitting: observer-rated defense mechanisms in borderline personality disorder

Defense mechanism is a key concept in the psychoanalytic psychopathology of borderline personality disorder (BPD). Theoretical and empirical elaborations on this question are briefly reviewed and discussed with respect to process assessment of defense mechanisms; we put forward observer-rater methodology as an accurate means of assessing unconscious in-session processes. A sample of 25 patients presenting with BPD were interviewed, as were subjects from a matched control group without psychiatric symptoms (n = 25), using a psychodynamic interview paradigm. These interviews were transcribed and rated using the Defense Mechanisms Rating Scales. The results indicate that, compared to controls, patients with BPD used higher percentages of a action, borderline, disavowal, narcissistic, and hysteric defenses, along with lower levels of mature and obsessional defenses. Overall defensive functioning was significantly lower in the patients with BPD, compared to controls. Narcissistic defenses were related with symptom level. These results are discussed in light of previous studies on defensive functioning of BPD and the literature on psychoanalytic psychopathology. These results have several important clinical implications.

Pretreatment and outcome correlates of past sexual and physical trauma in 118 bipolar I disorder patients with a first episode of psychotic mania.

OBJECTIVES: To assess the prevalence and correlates of childhood and adolescent sexual and/or physical abuse (SPA) in bipolar I disorder (BDI) patients treated for a first episode of psychotic mania. METHODS: The Early Psychosis Prevention and Intervention Centre admitted 786 first-episode psychosis patients between 1998 and 2000. Data were collected from patients' files using a standardized questionnaire. A total of 704 files were available; 43 were excluded because of a nonpsychotic diagnosis at endpoint and 3 due to missing data regarding past stressful events. Among 658 patients with available data, 118 received a final diagnosis of BDI and were entered in this study. RESULTS: A total of 80% of patients had been exposed to stressful life events during childhood and adolescence and 24.9% to SPA; in particular, 29.8% of female patients had been exposed to sexual abuse. Patients who were exposed to SPA had poorer premorbid functioning, higher rates of forensic history, were less likely to live with family during treatment period, and were more likely to disengage from treatment. CONCLUSIONS: SPA is highly prevalent in BDI patients presenting with a first episode of psychotic mania; exposed patients have lower premorbid functional levels and poorer engagement with treatment. The context in which such traumas occur must be explored in order to determine whether early intervention strategies may contribute to diminish their prevalence. Specific psychological interventions must also be developed.

The value of 'positive' clinical signs for weakness, sensory and gait disorders in conversion disorder: a systematic and narrative review.

Experts in the field of conversion disorder have suggested for the upcoming DSM-V edition to put less weight on the associated psychological factors and to emphasise the role of clinical findings. Indeed, a critical step in reaching a diagnosis of conversion disorder is careful bedside neurological examination, aimed at excluding organic signs and identifying 'positive' signs suggestive of a functional disorder. These positive signs are well known to all trained neurologists but their validity is still not established. The aim of this study is to provide current evidence regarding their sensitivity and specificity. We conducted a systematic search on motor, sensory and gait functional signs in Embase, Medline, PsycINfo from 1965 to June 2012. Studies in English, German or French reporting objective data on more than 10 participants in a controlled design were included in a systematic review. Other relevant signs are discussed in a narrative review. Eleven controlled studies (out of 147 eligible articles) describing 14 signs (7 motor, 5 sensory, 2 gait) reported low sensitivity of 8-100% but high specificity of 92-100%. Studies were evidence class III, only two had a blinded design and none reported on inter-rater reliability of the signs. Clinical signs for functional neurological symptoms are numerous but only 14 have been validated; overall they have low sensitivity but high specificity and their use should thus be recommended, especially with the introduction of the new DSM-V criteria.

Quetiapine dosage in bipolar disorder episodes and mixed states

OBJECTIVE: Although the maximal quetiapine doses in the published studies were restricted to 800 mg/day, higher quetiapine doses are not unusual in clinical practice. The aim of the present study was to evaluate the effectiveness, tolerability and clinical reasons associated to the use of high dosage of quetiapine (>800 mg), when used under routine clinical conditions, in a sample of bipolar disorder and schizoaffective bipolar inpatients. METHODS: Charts of all bipolar and schizoaffective adult inpatients, who had received quetiapine for a mood episode between 1999 and 2005 were retrospectively reviewed. These charts also included the assessment of manic and depressive symptoms on admission and at discharge using the Beck-Rafaelsen Mania Scale (MAS) and the Montgomery Asberg depression rating scale (MADRS), respectively. RESULTS: Data of 50 patients were analyzed. The overall F in repeated measures ANOVA revealed a significant MAS scores reduction between admission and discharge. MAS scores reduction did not differ between the high and low quetiapine groups. Similarly, a significant MADRS reduction was found. Again, no differences between the high and the low dose group were found. Logistic regression analysis of the 50 patients revealed only mixed episodes predicted high quetiapine dosage. CONCLUSIONS: The present study confirms quetiapine efficiency and tolerability in the treatment of bipolar episodes, even in doses > to 800 mg and found a link between quetiapine doses and mixed episodes

Binge drinking in 19 year old men.

QUESTION UNDER STUDY: To describe alcohol use, binge drinking and drinking consequences in 19 year old men. METHODS: During a one-day army recruitment process mandatory for all Swiss males, a convenience sample of 1,004 men completed the "Health and Lifestyle Questionnaire", assessing demographics, alcohol use, binge drinking, and drinking consequences over the last 12 months. Binge drinking was defined as having 5 or more drinks on a single occasion at least once over the last 12 months. Among the 1,004 subjects, binge drinking could not be defined in 123 (12.3%) due to "don't know" responses, leaving 881 subjects with complete data. RESULTS: Of the 881 subjects, 690 (78.3%) reported binge drinking at least once over the last 12 months, 269 (30.5%) with infrequent binge drinking (< or = 1x/month) and 421 (47.8%) with frequent binge drinking (> or = 2x/month). In addition, 379 (43.0%) of the subjects experienced 3 or more drinking consequences over the last 12 months and the number of these consequences increased as the frequency of binge drinking increased (trend analyses significant for 9 of the 12 consequences evaluated). Among the 687 subjects with moderate average alcohol intake (< 14 drinks per week), 252 (36.7%) reported infrequent binge drinking, of whom 82 (32.5%) experienced 3 or more adverse drinking consequences over the last 12 months, whereas 246 (35.8%) reported frequent binge drinking and 128 (52.0%) of these experienced 3 or more adverse drinking consequences. CONCLUSIONS: Binge drinking in this sample of young men is frequent and is associated with numerous consequences, even among those consuming moderate amounts of alcohol.

Genome-wide association study of recurrent major depressive disorder in two European case-control cohorts.

Major depressive disorder (MDD) is a highly prevalent disorder with substantial heritability. Heritability has been shown to be substantial and higher in the variant of MDD characterized by recurrent episodes of depression. Genetic studies have thus far failed to identify clear and consistent evidence of genetic risk factors for MDD. We conducted a genome-wide association study (GWAS) in two independent datasets. The first GWAS was performed on 1022 recurrent MDD patients and 1000 controls genotyped on the Illumina 550 platform. The second was conducted on 492 recurrent MDD patients and 1052 controls selected from a population-based collection, genotyped on the Affymetrix 5.0 platform. Neither GWAS identified any SNP that achieved GWAS significance. We obtained imputed genotypes at the Illumina loci for the individuals genotyped on the Affymetrix platform, and performed a meta-analysis of the two GWASs for this common set of approximately half a million SNPs. The meta-analysis did not yield genome-wide significant results either. The results from our study suggest that SNPs with substantial odds ratio are unlikely to exist for MDD, at least in our datasets and among the relatively common SNPs genotyped or tagged by the half-million-loci arrays. Meta-analysis of larger datasets is warranted to identify SNPs with smaller effects or with rarer allele frequencies that contribute to the risk of MDD.

État de stress post-traumatique chez les mères et chez les pères d'enfants prématurés: similitudes et différences = Prematurity and parental post-traumatic stress disorder: similarities and differences

Objectifs Évaluer et comparer la présence de symptômes de stress post-traumatique, en fonction de la gravité de la prématurité, chez les mères et chez les pères de bébés nés prématurément. Méthode En fonction du score de risque périnatal (PERI) du bébé, les parents des prématurés (âge gestationnel moins de 34 semaines) ont été divisés en deux groupes : les parents de prématurés à faible risque (n = 16) et à haut risque (n = 26). Les symptômes d'intrusion et d'évitement, de l'état de stress post-traumatique, ont été évalués chez les parents à l'aide d'un questionnaire, l'Impact of Event Scale (IES). Leurs réponses ont été comparées à un groupe témoin de parents de nouveau-nés à terme (n = 24). Les différences entre les réponses des mères et des pères, ont été analysées. Résultats Les parents de bébés prématurés sont plus à risque que les parents de nouveau-nés à terme de présenter des symptômes de stress post-traumatique. Les mères en lien avec le fait même de la prématurité du bébé, les pères en lien avec la gravité de la prématurité. Les mères et les pères des prématurés des deux groupes (prématurés à faible risque, prématurés à haut risque) décrivent des symptômes d'intrusion, alors que les symptômes d'évitement sont décrits par toutes les mères, mais seulement par les pères de prématurés à haut risque périnatal. Conclusion La naissance prématurée est susceptible d'entraîner l'apparition de symptômes de stress post-traumatique chez les parents. Les mères et les pères réagissent différemment. Objectives Evaluation of the symptoms of parental post-traumatic stress disorder (PTSD), according to the severity of the prematurity, in mothers and fathers of premature babies. Materials and methods According to the Perinatal Risk Inventory (PERI), the parents of premature infants (gestational age less than 34 weeks) were divided into two groups, parents of a low-risk premature infants (n = 16) and of high-risk premature infants (n = 26). The symptoms of intrusion and avoidance, as a part of the post-traumatic stress disorder, were evaluated by an autoadministrated questionnaire, the Impact of Event Scale (IES). Their responses were compared with a control group of parents of full-term infants (n = 24). The differences in the answers of mothers and fathers were analysed. Results The occurrence of symptoms of post-traumatic stress disorder is increased in parents of preterm infants compared with the control group. Whereas mothers of premature infants are at risk of presenting symptoms of PTSD, linked to the prematurity, with fathers the infant perinatal risk factors play a greater role. The symptoms of intrusion are present in mothers and fathers of preterm infants of both groups. Mothers of both groups present avoidance symptoms, although only fathers of high-risk preterm infants present them. Conclusions Premature birth has an impact on both parents in terms of post-traumatic stress reactions. However, mothers and fathers react in different ways according to the severity of the prematurity.

Syndrome des jambes sans repos chez la personne âgée: une affection méconnue [Restless legs syndrome in the elderly: an unrecognized disorder].

The restless legs syndrome (RLS) is a frequent, often unrecognized disorder in the elderly. The diagnosis is essentially based on the clinical history. The RLS is characterized by (1) an urge to move the limbs, usually associated with abnormal sensations in the legs; (2) symptoms are worse at rest; (3) they are relieved by movements; (4) they mainly occur in the evening or at night. Specific diagnostic criteria have been developed for cognitively impaired elderly persons. The RLS is a chronic disorder with high impact on sleep and quality of life. Treatment is symptomatic and recommended drugs are dopaminergic agents, opioids, and gabapentine.
