Tanning in body dysmorphic disorder.

Tanning in body dysmorphic disorder (BDD) has not previously been studied. In this study, 200 subjects with BDD were evaluated with measures to examine the prevalence of BDD-related tanning--i.e., darkening one's skin color by direct exposure to sunlight or artificial light which is motivated by a desire to improve a perceived appearance defect (i.e., a BDD concern). We also examined clinical characteristics of individuals who engaged in BDD-related tanning. 25% (95% CI, 19.0%-31.0%) of subjects reported BDD-related tanning. Among tanners, the skin was the most common body area of concern (84.0%). All tanners experienced functional impairment due to BDD, 26% had attempted suicide, and quality of life was markedly poor. 52% of tanners had received dermatologic treatment, which was usually ineffective for BDD symptoms. Tanners were more likely than non-tanners to compulsively pick their skin. In conclusion, tanning--a behavior with well-known health risks--is a relatively frequent BDD-related behavior.

Results of a naturalistic longitudinal study of benzodiazepine and SSRI use in the treatment of generalized anxiety disorder and social phobia.

The past decade has brought major new developments in the psychopharmacologic management of generalized anxiety disorder and social phobia. We examined medication-prescribing patterns for the treatment of these anxiety disorders for 12 years to assess changes in patients' anti-anxiety psychotropic medication usage during that period of evolving practice guidelines. We examined psychotropic medication use in 305 patients with generalized anxiety disorder and 232 with social phobia enrolled in the Harvard/Brown Anxiety Disorders Research Project (HARP), a prospective, longitudinal study of anxiety disorders. Psychotropic treatment patterns seem to have remained relatively stable over 12 years with benzodiazepines the medications most commonly used for both generalized anxiety disorder and social phobia. Comparatively, selective serotonin reuptake inhibitor (SSRI) and venlafaxine usage as stand-alone medications for these disorders remained low throughout the follow-up period. At the 12-year follow-up, 24% of patients with generalized anxiety disorder and 30% of patients with social phobia were utilizing neither an SSRI/selective norepinephrine reuptake inhibitor (SNRI) nor a benzodiazepine. Treatment recommendations for use of SSRIs and venlafaxine in the management of generalized anxiety disorder and social phobia initially promulgated in 1998 had a modest impact on changes in psychopharmacologic practice 4-5 years later. Difficulties in the implementation of treatment guidelines are discussed.

Two-year prevalence and stability of individual DSM-IV criteria for schizotypal, borderline, avoidant, and obsessive-compulsive personality disorders: toward a hybrid model of axis II disorders.

OBJECTIVE: This study tracked the individual criteria of four DSM-IV personality disorders-borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders-and how they change over 2 years. METHOD: This clinical sample of patients with personality disorders was derived from the Collaborative Longitudinal Personality Disorders Study and included all participants with borderline, schizotypal, avoidant, or obsessive-compulsive personality disorder for whom complete 24-month blind follow-up assessments were obtained (N=474). The authors identified and rank-ordered criteria for each of the four personality disorders by their variation in prevalence and changeability (remission) over time. RESULTS: The most prevalent and least changeable criteria over 2 years were paranoid ideation and unusual experiences for schizotypal personality disorder, affective instability and anger for borderline personality disorder, feeling inadequate and feeling socially inept for avoidant personality disorder, and rigidity and problems delegating for obsessive-compulsive personality disorder. The least prevalent and most changeable criteria were odd behavior and constricted affect for schizotypal personality disorder, self-injury and behaviors defending against abandonment for borderline personality disorder, avoiding jobs that are interpersonal and avoiding potentially embarrassing situations for avoidant personality disorder, and miserly behaviors and strict moral behaviors for obsessive-compulsive personality disorder. CONCLUSIONS: These patterns highlight that within personality disorders the relatively fixed criteria are more trait-like and attitudinal, whereas the relatively intermittent criteria are more behavioral and reactive. These patterns suggest that personality disorders are hybrids of traits and symptomatic behaviors and that the interaction of these elements over time helps determine diagnostic stability. These patterns may also inform criterion selection for DSM-V.

Influence of psychiatric comorbidity on recovery and recurrence in generalized anxiety disorder, social phobia, and panic disorder: a 12-year prospective study.

OBJECTIVE: The authors sought to observe the long-term clinical course of anxiety disorders over 12 years and to examine the influence of comorbid psychiatric disorders on recovery from or recurrence of panic disorder, generalized anxiety disorder, and social phobia. METHOD: Data were drawn from the Harvard/Brown Anxiety Disorders Research Program, a prospective, naturalistic, longitudinal, multicenter study of adults with a current or past history of anxiety disorders. Probabilities of recovery and recurrence were calculated by using standard survival analysis methods. Proportional hazards regression analyses with time-varying covariates were conducted to determine risk ratios for possible comorbid psychiatric predictors of recovery and recurrence. RESULTS: Survival analyses revealed an overall chronic course for the majority of the anxiety disorders. Social phobia had the smallest probability of recovery after 12 years of follow-up. Moreover, patients who had prospectively observed recovery from their intake anxiety disorder had a high probability of recurrence over the follow-up period. The overall clinical course was worsened by several comorbid psychiatric conditions, including major depression and alcohol and other substance use disorders, and by comorbidity of generalized anxiety disorder and panic disorder with agoraphobia. CONCLUSIONS: These data depict the anxiety disorders as insidious, with a chronic clinical course, low rates of recovery, and relatively high probabilities of recurrence. The presence of particular comorbid psychiatric disorders significantly lowered the likelihood of recovery from anxiety disorders and increased the likelihood of their recurrence. The findings add to the understanding of the nosology and treatment of these disorders.

Axis I and axis II disorders as predictors of prospective suicide attempts: findings from the collaborative longitudinal personality disorders study.

This study examined diagnostic predictors of prospectively observed suicide attempts in a personality disorder (PD) sample. During 2 years of follow-up, 58 participants (9%) reported at least 1 definitive suicide attempt. Predictors that were examined include 4 PD diagnoses and selected Axis I diagnoses (baseline and course). Multivariate logistic regression analyses indicated that baseline borderline personality disorder (BPD) and drug use disorders significantly predicted prospective suicide attempts. Controlling for baseline BPD diagnosis, proportional hazards analyses showed that worsening in the course of major depressive disorder (MDD) and of substance use disorders in the month preceding the attempt were also significant predictors. Therefore, among individuals diagnosed with PDs. exacerbation of Axis I conditions, particularly MDD and substance use, heightens risk for a suicide attempt.

Submicroscopic deletions at 7q region are associated with recurrent chromosome abnormalities in acute leukemia.

BACKGROUND AND OBJECTIVES: Loss of heterozygosity (LOH) on the long arm of chromosome 7 (7q) has been frequently reported in several types of human cancer including hematologic malignancies. Moreover, monosomy of chromosome 7 and 7q deletions have been associated in acute myeloid leukemia (AML) with aggressive disease and poor prognosis. DESIGN AND METHODS: Using a panel of 11 polymorphic microsatellite markers at bands 7q21-q36, we investigated fifty patients (acute myeloid leukemia [AML], n=33 and acute lymphoid leukemia [ALL], n=17) for LOH, a hallmark of possible involvement of tumor suppressor genes. In parallel, the same acute leukemia (AL) cases were studied by conventional cytogenetics. RESULTS: A total of 48 spots of allelic loss were observed in 16 (32%) out of 50 patients (AML, n=11 and ALL, n=5). Among LOH+ve cases 3 showed chromosome 7 monosomies, whereas no cytogenetically detectable abnormalities were observed in chromosome 7 in the remaining 13. INTERPRETATION AND CONCLUSIONS: Comparison with karyotypic results indicated that presence of LOH at 7q21-q36 was significantly associated with other chromosomal aberrations. In fact, an altered karyotype was detectable in 87% of LOH+ve and in 52% of LOH(-ve) AL cases (p=0.024). In addition, LOH at 7q was prevalently associated with unfavorable cytogenetic lesions (p=0.013). Our study represents the first report of a significant association between LOH and recurrent chromosomal abnormalities in AL patients suggesting that the 7q21-q36, region may be an unstable area prone to chromosome breakage in patients with an abnormal karyotype.

Circulating hematopoietic progenitor cells in runners.

Because endurance exercise causes release of mediators and growth factors active on the bone marrow, we asked whether it might affect circulating hematopoietic progenitor cells (HPCs) in amateur runners [n = 16, age: 41.8 +/- 13.5 (SD) yr, training: 93.8 +/- 31.8 km/wk] compared with sedentary controls (n = 9, age: 39.4 +/- 10.2 yr). HPCs, plasma cortisol, interleukin (IL)-6, granulocyte colony-stimulating factor (G-CSF), and the growth factor fms-like tyrosine kinase-3 (flt3)-ligand were measured at rest and after a marathon (M; n = 8) or half-marathon (HM; n = 8). Circulating HPC counts (i.e., CD34(+) cells and their subpopulations) were three- to fourfold higher in runners than in controls at baseline. They were unaffected by HM or M acutely but decreased the morning postrace. Baseline cortisol, flt3-ligand, IL-6, and G-CSF levels were similar in runners and controls. IL-6 and G-CSF increased to higher levels after M compared with HM, whereas cortisol and flt3-ligand increased similarly postrace. Our data suggest that increased HPCs reflect an adaptation response to recurrent, exercise-associated release of neutrophils and stress and inflammatory mediators, indicating modulation of bone marrow activity by habitual running.
