La Passion Bartleby ou la passion en négatif

Bartleby, by Melville, a pale character who by his strange formula, unleashes passions within and outside the novel. From literature to psychoanalysis via philosophy and psychiatry, the author will go through the various attempts to shed light on this enigmatic passion.     

Auditory tasks for assessment of sensory function and affective prosody in schizophrenia

Schizophrenia patients exhibit impairments in auditory-based social cognition, indicated by deficits in detection of prosody, such as affective prosody and basic pitch perception. However, little is known about the psychometric properties of behavioral tests used to assess these functions. The goal of this paper is to characterize the properties of prosody and pitch perception tasks and to investigate whether they can be shortened. The pitch perception test evaluated is a tone-matching task developed by Javitt and colleagues (J-TMT). The prosody test evaluated is the auditory emotion recognition task developed by Juslin and Laukka (JL-AER). The sample includes 124 schizophrenia patients (SZ) and 131 healthy controls (HC). Properties, including facility and discrimination, of each item were assessed. Effects of item characteristics (e.g., emotion) were also evaluated. Shortened versions of the tests are proposed based on facility, discrimination, and/or ability of item characteristics to discriminate between patients and controls. Test–retest reliability is high for patients and controls for both the original and short forms of the J-TMT and JL-AER. Thus, the original as well as short forms of the J-TMT and JL-AER are suggested for inclusion in clinical trials of social cognitive and perceptual treatments. The development of short forms further increases the utility of these auditory tasks in clinical trials and clinical practice. The large SZ vs. HC differences reported here also highlight the profound nature of auditory deficits and a need for remediation.     

Validation of an Arabic multi-informant psychiatric diagnostic interview for children and adolescents: Development and Well Being Assessment-Arabic (DAWBA-Arabic)

Background

Countries in the Arab region lack a valid Arabic psychiatric diagnostic interview for children and adolescents. We set out to establish the diagnostic validity of the Arabic version of the Development and Well Being Assessment (DAWBA-Arabic), a multi-informant structured interview for predicting DSM-IV-TR diagnoses.

Methods

The DAWBA was translated, updated, and administered to 45 participants (child and adolescent psychiatric outpatients and their parents) as part of a clinic registry. Two clinicians, blinded to their respective diagnoses, formulated the DAWBA diagnoses. Participants also underwent a clinical evaluation by a child and adolescent psychiatrist who generated clinical diagnoses according to the DSM-IV-TR.

Results

Inter-rater reliabilities were .93, .82, and .72 for disruptive disorders, mood disorders and anxiety disorders respectively. Agreement between DAWBA and clinical diagnoses was substantial for disruptive disorders (κ = .0.82) and mood disorders (κ = 0.74), and moderate for anxiety disorders (κ = 0.46).

Conclusion

The DAWBA-Arabic could serve as a valid and reliable clinical tool for assessing psychiatric disorders among children and adolescents in the Arab region.     

Reliability and validity of the Arabic Screen for Child Anxiety Related Emotional Disorders (SCARED) in a clinical sample

This study aimed at investigating the reliability and validity of the Arabic Screen for Child Anxiety Related Emotional Disorders (SCARED) as a first child and adolescent anxiety screening tool in the Arab World. The English parent (SCARED-P) and child (SCARED-C) versions were translated into Arabic and administered along with the Arabic Strengths and Difficulties Questionnaire (SDQ) to 77 parents and 67 children attending a Psychiatry clinic. DSM-IV-TR diagnoses were made by a psychiatrist without knowledge of the scale scores. Internal consistency was confirmed by Cronbach's α=0.92 for SCARED-P and 0.91 for SCARED-C. Their subscales had internal consistencies between 0.65 and 0.89. Parent–child agreement was r=0.67, p<0.001. SCARED-P demonstrated good discriminant validity between participants with anxiety disorders and those with other psychiatric disorders (t(72)=3.13, p=0.003). For SCARED-C, this difference was significant when participants with depressive disorders were excluded (t(43)=2.58, p=0.01). Convergent validity was evident through a significant correlation between SCARED-P and the parent SDQ emotional subscale (r=0.70, p<0.001), and SCARED-C and the child SDQ emotional subscale (r=0.70, p<0.001). Divergent validity with the SDQ hyperactivity subscale was observed as no significant correlation was found. Overall, the Arabic SCARED demonstrated satisfactory psychometric properties in a clinical sample in Lebanon.     

One Thousand Consecutive Mini-Gastric Bypass: Short- and Long-term Outcome

There is growing evidence that mini-gastric bypass (MGB) is a safe and effective procedure. Operative outcome and long-term follow-up of a consecutive cohort of patients who underwent MGB are reported. The data on 1,000 patients who underwent MGB from November 2005 to January 2011 at an academic institution were reviewed. Mean age was 33.15 ± 10.17 years (range, 14–72), preoperative BMI was 42.5 ± 6.3 kg/m² (range, 26–75), mean preoperative weight was 121.6 ± 23.8 kg (range, 71–240), and 663 were women. Operative time and length of stay for primary vs. revisional MGB were 89 ± 12.8 min vs. 144 ± 15 min (p < 0.01) and l.85 ± 0.8 day vs. 2.35 ± 1.89 day (p < 0.01). No deaths occurred within 30 days of surgery. Short-term complications occurred in 2.7% for primary vs. 11.6% for revisionnal MGB (p < 0.01). Five (0.5%) patients presented with leakage from the gastic tube but none had anastomotic leakage. Four (0.4%) patients, all with revisionnal MGB, presented with severe bile reflux and were cured by stapling the afferent loop and by a latero-lateral jejunojejunostomy. Excessive weight loss occurred in four patients; two were reversed and two were converted to sleeve gastrectomy. Maximal percent excess weight loss (EWL) of 72.5% occurred at 18 months. Weight regain subsequently occurred with a mean variation of −3.9% EWL at 60 months. The 50% EWL was achieved for 95% of patients at 18 months and for 89.8% at 60 months. MGB is an effective, relatively low-risk, and low-failure bariatric procedure. In addition, it can be easily revised, converted, or reversed.     

New trends in the management of head and neck cancers

Head and neck cancers affect more than half million person a year worldwide. More than 40% have an advanced stage at diagnosis. The incidence in Lebanon according to the statistics of the Ministry of Public Health was 268 new cases in 2007. The tumors and their treatment modalities have an important impact on the quality of life because they influence communication, breathing and4 swallowing. Treatment modalities are evolving to more conservative approaches for better functional results without impeding survival. We present in this review the state of the art of the management of head and neck cancer in 2011 with emphasis on the most recent advances in the assessment, treatment and follow-up.
