Taboo thoughts and doubt/checking: a refinement of the factor structure for obsessive-compulsive disorder symptoms

The purpose of this report was to improve upon earlier factor analyses of obsessive-compulsive disorder (OCD) symptom categories by minimizing the heterogeneity in the aggressive obsessions category. An exploratory factor analysis was conducted on data from 293 adults with primary OCD. The resulting five factors (Symmetry/Ordering, Hoarding, Doubt/Checking, Contamination/Cleaning, and Taboo Thoughts) are phenomenologically more homogeneous than prior category-based factors and are consistent with those derived in previous item-level analyses.     

Olfaction in dentistry

Oral Diseases (2010) 16 , 221–232 Practitioners of oral medicine frequently encounter patients with complaints of taste disturbance. While some such complaints represent pathological processes specific to the gustatory system, per se, this is rarely the case. Unless taste‐bud mediated qualities such as sweet, sour, bitter, salty, umami, chalky, or metallic are involved, ‘taste’ dysfunction inevitably reflects damage to the sense of smell. Such ‘taste’ sensations as chicken, chocolate, coffee, raspberry, steak sauce, pizza, and hamburger are dependent upon stimulation of the olfactory receptors via the nasopharynx during deglutition. In this paper, we briefly review the anatomy, physiology, and pathophysiology of the olfactory system, along with means for clinically assessing its function. The prevalence, etiology, and nature of olfactory disorders commonly encountered in the dental clinic are addressed, along with approaches to therapy and patient management.     

Functional impairment in body dysmorphic disorder: a prospective, follow-up study

Cross-sectional/retrospective studies indicate that individuals with body dysmorphic disorder (BDD) have markedly impaired psychosocial functioning. However, no study has prospectively examined functioning in BDD. In this study, which is to our knowledge the first prospective study of the course of BDD, psychosocial functioning was assessed at baseline and over 1–3 years (mean = 2.7 ± 0.9 years) of follow-up with the Global Assessment of Functioning scale (GAF), Social and Occupational Functioning Scale (SOFAS), and LIFE-RIFT (Range of Impaired Functioning Tool). Psychosocial functioning was poor during the follow-up period. Functioning remained stably poor over time on the SOFAS and LIFE-RIFT, although there was a trend for a gradual and slight improvement on the GAF over time. The cumulative probability of attaining functional remission on the GAF (score > 70 for at least 2 consecutive months) during the follow-up period was only 5.7%. On the SOFAS, the cumulative probability of attaining functional remission (score > 70 for at least 2 consecutive months) was 10.6%. BDD severity significantly predicted functioning on the GAF (p = 0.0012), SOFAS (p = 0.0017), and LIFE-RIFT (p = 0.0015). A trend for a time-by-BDD severity interaction was found on the GAF (p = 0.033) but not the SOFAS or LIFE-RIFT. More delusional BDD symptoms also predicted poorer functioning on all measures, although this finding was no longer significant when controlling for BDD severity. Functioning was not predicted, however, by age, gender, BDD duration, or a personality disorder. In conclusion, psychosocial functioning was poor over time, and few subjects attained functional remission. Greater BDD severity predicted poorer functioning.     

Three-year results of mandated work hour restrictions: attending and resident perspectives and effects in a community hospital

In response to the Accreditation Council of Graduate Medical Education mandated resident work hour restrictions, our residency program used a night float system in 2003. We undertook a survey of attending staff and residents to assess its effects on patient care and resident education. An anonymous survey was administered to attending staff and residents 1 year and 3 years after work hour restrictions took effect. The areas of disagreement include: beneficial effect on education (residents vs faculty: in 2004, 87% vs 22%, respectively, P = 0.02; in 2006, 71% vs 22%, P = 0.03); beneficial effect on patient care (in 2004, 53% vs 10%, P = 0.03); and compromised continuity of care (in 2004, 27% vs 70%, P = 0.04; in 2006, 7% vs 89%, P = 0.0002). One area of agreement was that residents' quality of life had improved. Both disagreed that more errors were being made and that work hour restrictions should be mandated on practicing surgeons. Attending staff and residents have deeply held opinions regarding the effects of work hour restrictions. This reflects a continuing dissatisfaction with providing patient care and educating residents under a set of requirements that solely addresses resident sleepiness and fatigue.
