OBJECTIVES

To characterize clinical and imaging features in patients with pathologically confirmed demyelinating lesions.

METHODS

In this retrospective chart review, we analyzed clinical-radiological-pathological correlations in patients >15years old who underwent brain biopsy at our institution between 2000 and 2015 and had inflammatory demyelination on neuropathology.

RESULTS

Of 31 patients, the mean age was 42years (range 16 to 69years) and 55% were female. All but one of the biopsied lesions were considered tumefactive demyelinating lesions (TDLs) by imaging criteria, measuring >2cm on contrast-enhanced brain MRI. On clinical follow-up, the final diagnosis was a CNS malignancy in 2 patients (6.5%). In patients without malignant tumor, the TDL was solitary in 12 (41%) and multifocal in 17 (59%), with contrast enhancement in all but one case, primarily in an incomplete rim enhancement pattern (75.9%). Of 16 patients with at least 12months of clinical follow-up, 7 (43.8%) had a clinical relapse. Of patients without a prior neurologic history, relapse occurred in 2/7 (29%) in solitary TDL and 2/6 (33%) in multifocal lesions at initial presentation. Recurrent TDLs occurred in 3 patients, all with initially solitary TDLs. Stratifying by CSF analysis, 4 of 6 patients (67%) with either an elevated IgG Index or >2 oligoclonal bands suffered a clinical relapse compared to 2/8 (25%) with non-inflammatory CSF.

CONCLUSIONS

Pathologically confirmed TDLs call for careful clinical correlation, clinical follow-up and imaging surveillance. Although sometimes clinically monophasic, tumefactive demyelinating lesions carried nearly a 45% risk of near-term clinical relapse in our study, even when presenting initially as a solitary mass lesion.

The purpose of this study is to compare disease severity in ankylosing spondylitis (AS) in three ethnic groups. We assessed 925 AS patients (57 Blacks, 805 Whites, 63 Latinos) enrolled in the longitudinal Prospective Study of Outcomes in AS (PSOAS) for functional impairment, disease activity, and radiographic severity. Comparisons of clinical characteristics and HLA-B27 frequency for each group were performed, in two multivariable regression models, we compared the baseline Bath Ankylosing Spondylitis Radiographic Index (BASRI) and modified Stokes Ankylosing Spondylitis Spine Score (mSASSS) by ethnicity, adjusting for covariates. Blacks had greater functional impairment (Bath Ankylosing Spondylitis Functional Index) (median 62.5 vs. 27.8 in Whites and 38.1 in Latinos; p  0.0001); higher disease activity (Bath Ankylosing Spondylitis Disease Activity Index), (median 5.9 vs. 3.5 in Whites and 4.5 in Latinos; p  0.0001), erythrocyte sedimentation rate (median 27.0 in Blacks vs. 10.0 in Whites and 17.0; p  0.0001), and C-reactive protein levels (median 1.2 vs. 0.4 mg/dL in Whites and 0.9 in Latinos; p  0.0001). Baseline BASRI and mSASSS were higher in Blacks (mean 9.5 and median 38.2, respectively) compared to Whites (7.3 and 6.4) and Latinos (7.3 and 8.1), (p = 0.004, 0.007), respectively, more significant as disease duration increased. HLA-B27 occurred in 62.5% of Blacks, 85.3% of Whites, and 86.7% of Latinos (p  0.0001). On multivariable analysis, higher BASRI and mSASSS were associated with Black ethnicity, after adjusting for disease duration and gender as well as TNF inhibitor (TNFi) usage, smoking status, or education level. Blacks with AS have more severe disease compared to either Whites or Latinos.

CONTEXT

This article describes the scholarly work that has addressed the fifth recommendation of the 1988 World Conference on Medical Education: 'Train teachers as educators, not content experts alone, and reward excellence in this field as fully as excellence in biomedical research or clinical practice'.

PROGRESS

Over the past 30 years, scholars have defined the preparation needed for teaching and other educator roles, and created faculty development delivery systems to train teachers as educators. To reward the excellence of educators, scholars have expanded definitions of scholarship, defined educator roles and criteria for judging excellence, and developed educator portfolios to make achievements visible for peer review. Despite these efforts, the scholarship of discovery continues to be more highly prized and rewarded than the scholarship of teaching. These values are deeply embedded in university culture and policies.

CHALLENGES

To remedy the structural inequalities between researchers and educators, a holistic approach to rewarding the broad range of educational roles and educational scholarship is needed. This requires strong advocacy to create changes in academic rewards and support policies, provide a clear career trajectory for educators using learning analytics, expand programmes for faculty development, support health professions education scholarship units and academies of medical educators, and create mechanisms to ensure high standards for all educators.

BACKGROUND/OBJECTIVES

Digital video is widely available and is used sporadically in clinical settings to evaluate patients, but whether it helps improve clinical management has not been determined. The aim of this study was to assess whether recorded video in addition to still images can improve residents' diagnostic and management accuracy and confidence with pediatric teledermatology cases.

METHODS

Dermatology residents from three programs were assigned alternately to an online survey with 15 pediatric teledermatology cases presented with still images only (still) or still images plus recorded video (mixed). Participants provided free-text diagnoses and management recommendations and rated their confidence and image quality. Responses were scored using a modified script concordance grading key based on reference panelists' responses.

RESULTS

Thirty-one residents participated (response rate 57%). Participants in the mixed group scored significantly higher on management accuracy (87.6 ± 12.9 vs 71.7 ± 14.2; p = 0.003). Both groups performed better on more common conditions than less common conditions. The mixed group outperformed the still group on less common conditions with respect to management recommendations.

CONCLUSION

This novel study suggests that supplemental recorded video may improve the management accuracy of pediatric teledermatology consultations, particularly for complex cases. Residents may benefit from training in recording and interpreting video.

INTRODUCTION

Although HIV stigma has been identified as an important risk factor for HIV transmission risk behaviors, little is known about the contribution of community-level HIV stigma to HIV transmission risk behaviors and self-reported sexually transmitted diseases (STDs) or how gender may modify associations.

METHODS

We pooled data from the 2008 and 2013 Sierra Leone Demographic and Health Surveys. For HIV stigma, we examined HIV stigmatizing attitudes and HIV disclosure concerns at both individual and community levels. Outcomes of HIV transmission risk behaviors were recent condom usage, consistent condom usage, and self-reported STDs. We assessed associations with multivariable logistic regressions. We also analyzed gender as an effect modifier of these associations.

RESULTS

Of 34,574 respondents, 24,030 (69.5%) who had heard of HIV were included in this analysis. Community-level HIV stigmatizing attitudes and disclosure concerns were associated with higher odds of self-reported STDs (adjusted odds ratio = 2.07; 95% confidence interval: 1.55 to 2.77; adjusted odds ratio = 2.95; 95% confidence interval: 1.51 to 5.58). Compared with men, community-level HIV stigmatizing attitudes among women were a stronger driver of self-reported STDs (interaction P = 0.07). Gender modified the association between community-level HIV disclosure concerns and both recent and consistent condom usage (interaction P = 0.03 and P = 0.002, respectively). Community-level HIV disclosure concerns among women were observed to be a driver of risky sex and self-reported STDs.

CONCLUSIONS

This study shows that community-level HIV stigma may be a driver for risky sex and self-reported STDs, particularly among women. Our findings suggest that community-held stigmatizing beliefs and HIV disclosure concerns among women might be important targets for HIV stigma reduction interventions.

GOALS

To evaluate provider knowledge, attitudes and barriers to hepatitis B virus (HBV) care and management practices across diverse primary care settings.

BACKGROUND

Factors influencing adherence to recommended HBV screening and management guidelines are poorly defined.

MATERIALS AND METHODS

Providers across various health care settings in San Francisco were surveyed. Multivariate analyses were used to identify factors associated with recommended HBV screening, vaccination, and disease monitoring.

RESULTS

Of 277 (41.3%) responding providers, 42% reported performing HBV screening in >50% of at-risk patients, and 49%, HBV vaccination in >50% of eligible patients. Most reported appropriate monitoring of a majority of HBV-infected patients with alanine aminotransferase (79%) and HBV viral load (67%) every 6 to 12 months, but performed any hepatocellular carcinoma screening in 49%. Provider factors significantly associated with HBV screening were speaking an Asian language [odds ratio (OR), 3.27], offering HBV treatment (OR, 3.00), having >25% of Asian patients in practice (OR, 2.10), practicing in safety net settings (OR, 7.51) and having higher barrier score (OR, 0.74). Appropriate HBV monitoring was associated with provider speaking an Asian language (OR, 3.43) and provider age (OR, 0.68/decade). Hepatocellular carcinoma screening was associated with having >25% of patients speaking English as a second language (OR, 4.26) and practicing in safety net settings (OR, 0.14).

CONCLUSIONS

Rates of adherence to HBV guidelines were suboptimal irrespective of practice setting and were influenced by certain provider, patient and practice factors. This study reinforces the importance of engaging primary care providers in development, dissemination, and implementation of evidence-based HBV practice guidelines.
