Objective To determine whether physician's attitudes toward patients with comorbid mental illness affect management of a chronic disease. Data Source A total of 256 primary care physicians interviewed in 2010. Study Design This randomized factorial experiment entailed physicians observing video vignettes of patient-actors with poorly controlled diabetes. Patients were balanced across age, gender, race, and comorbidity (schizophrenia with bizarre or normal affect, depression, eczema). Data Collection Physicians completed structured and semistructured interviews plus chart notes about clinical management and attitudes. Principal Findings Physicians reported more negative attitudes for patients with schizophrenia with bizarre affect ( SBA). There were few differences in clinical decisions measured quantitatively or in charting, but qualitative data revealed less trust of patients with SBA as reporters, with more reliance on sources other than engaging the patient in care. Physicians often alerted colleagues about SBA, thereby shaping expectations before interactions occurred. Conclusions Results are consistent with common stereotypes about people with serious mental illness. Vignettes did not include intentional indication of unreliable reporting or danger. Reducing health care disparities requires attention to subtle aspects of managing patients-particularly those with atypical affect-as seemingly slight differences could engender disparate patient experiences over time.

Objective Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection (PANDAS) should be considered in sudden onset, prepubertal Anorexia Nervosa (AN), arising shortly after an apparent streptococcal infection. However, the absence of a specific biological marker of PANDAS renders the diagnosis difficult. This paper critically reviews available tests for PANDAS and recommends a standardized approach to its investigation. Method Medline database review between 1990 and 2008. Results Existing tests may be categorized as: (i) Non-specific markers of inflammation or immune response (Erythrocyte sedimentation rate, ESR; C-reactive protein, CRP; Neopterin), (ii) specific markers of streptococcal infection (throat swab and anti-streptococcal antibodies, Anti-streptolysin, ASO; Antideoxyribonuclease B, antiDNaseB), (iii) non-specific markers of auto-immune reaction (Antineuronal antibodies, AnAb; D8/17). No one test reliably identifies PANDAS. The lack of specificity and methodological problems may lead to errors of diagnosis. Discussion When PANDAS–Anorexia Nervosa (PANDAS–AN) is suspected clinically we recommend conducting all the above investigations. The more positive results there are the more likely is the diagnosis, but particular weighting should be given to AnAb and D8/17.
