A decade of burn unit experience with Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: Clinical pathological diagnosis and risk factor awareness.

Stevens-Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN) is a rare and often fatal spectrum of mucocutaneous diseases usually attributable to severe adverse drug reactions. Burn units are referral centers for patients at the most extreme end of the disease continuum. Our burn center admits a much higher percentage of TEN (>30% BSA) cases than reported in most prior reviews. The purpose of this study was to analyze the diagnostic and prognostic value of variables collected on referred SJS/TEN patients. We retrospectively analyzed 94 patients admitted to our unit with a presumptive SJS/TEN diagnosis made in most cases by the referring center. Most of the diagnoses were clinical. Fifty of the 94 patients underwent biopsy when the clinical diagnosis was questionable. Of the 50 patients who underwent biopsy, 18 (36%) received an alternative diagnosis. Analysis was therefore limited to 76 patients, i.e. 44 patients felt to have firm clinical diagnoses plus 32 patients with diagnoses confirmed by biopsy. Mean age was 54.3 years (17-93) and overall gender ratio was 43 F vs. 33 M (56.6% vs. 43.4%). Mean LOS was 15.2 days (1-48) and overall mortality was 23.7% (18/76). Univariate analysis revealed percent body surface area (%BSA) did not show statistically significant association with mortality. Histopathological correlation for diagnosis is not standardized across institutions worldwide. Due to challenges in the diagnosis of SJS/TEN and the high incidence of error in clinical diagnosis, it is recommended that all patients with presumed SJS/TEN receive skin biopsies with H&E and direct immunofluorescence. We propose a diagnostic approach in order to address this need. Lack of association between %BSA and mortality suggests that all biopsy-proven SJS/TEN cases belong in specialty centers due to the unstable nature of the disease and risk for rapid progression.

Patterns of tobacco-use behavior among Chinese smokers with medical conditions.

Understanding the characteristics of Chinese American smokers with medical conditions and factors associated with their tobacco-use behaviors will guide effective cessation programs. In 2008, the authors described socio-demographic profiles of Chinese smokers with medical conditions treated during the period 2002-2006, documented their tobacco-use behaviors (i.e., average daily cigarette use, nicotine dependence, and number of past-year quit attempts), and drew comparisons between subjects recruited from hospitals (IP) and ambulatory settings (OP). Compared to OP, IP were significantly older, less educated, less acculturated, and more likely to be retired. Of the two groups, IP had poorer disease profiles, smoked less (4.4 vs. 11.9 cigarettes per day), and had lower nicotine-addiction scores (5.5 vs. 6.7). There was no difference between groups in past-year quit attempts. After adjustments, the data revealed that being employed and OP was associated with higher average daily cigarette use; IP were less nicotine dependent than OP; and for both groups, years of smoking was negatively associated with past-year quit attempts. Our study suggests that, more than acculturation level, health status influences the Chinese smoker's level of cigarette use and nicotine addiction. Given the severity of their disease profiles, IP should be aggressively targeted for intervention, as they are more likely to be light smokers and to be less nicotine dependent than OP. Future tobacco treatment studies should pay attention to health status among smokers in health-care settings in order to provide a more accurate assessment of treatment needs and of barriers to successful smoking cessation.

The Chinese community smoking cessation project: a community sensitive intervention trial.

This paper describes (1) the design, methods and baseline data of the first smoking cessation clinical trial for Chinese Americans with medical conditions - Chinese Community Smoking Cessation Project (CCSCP); (2) the collaborative process between researchers and the Chinese community; and (3) the barriers and facilitators of implementing the study. CCSCP was a culturally tailored, randomized, smoking cessation trial testing the efficacy of an intensive (physician advice, in-person counseling with nicotine replacement therapy, 5 telephone calls) compared to a minimal (physician advice and self-help manual) intervention. The study applied a community-sensitive research method involving community members in all phases of the research process in San Francisco Bay Area during 2001-2007. CCSCP recruited 464 smokers from health care facilities (79%) located in Chinese neighborhoods and through Chinese language media (21%). Baseline assessments and interventions were conducted in-person using translated and tested questionnaire and intervention materials. The majority of the participants were men (91%) with a mean age of 58.3 years, foreign born (98%), with less than high school education (58%), spoke no English (42%) and in non-skilled or semi-skilled occupations (60%) with <$20,000 household income (51%). Participants smoked regularly on an average 38.6 +/- 17 years, smoked 9.1 +/- 8 cigarettes per day and 85% smoked daily. Cultural tailoring of recruitment methods and intervention design led to successful enrollment and retention of participants, overcoming barriers faced by the participants. Community sensitive collaborative process facilitated implementation of study protocol in community health care settings.
