A panel of 43 early onset pauciarticular (EOPA) juvenile chronic arthritis (JCA) patients have been typed for human leucocyte antigens (HLA) DRB1, DPB1, DQA1 alleles, and DQB1*0603 status using molecular-based methods. Increased frequencies of DRB1*08 [odds ratio (OR) 7.7, 95% confidence interval (CI) 2.6-22.3], DRB1*11 (OR 3.1, 95% CI 1.2-8.1), DRB1*1301 (OR 7.7, 95% CI 2.6-22.3), DPB1*0201 (OR 3.5, 95% CI 1.6-8.0), DQA1*0103 (OR 4.4, 95% CI 1.5-13.3), DQA1*0501 (OR 2.9, 95% CI 1.3-6.6), DQA1*0601 (OR 30, 95% CI 3.6-241) and DQB1*0603 (OR 7.3, 95% CI 3.0-17.6) were found in the EOPA-JCA group compared with Caucasoid controls. Stratification of the EOPA-JCA group into antinuclear antibody (ANA) positive (n = 18) and ANA negative (n = 25) individuals revealed that ANA positivity was only associated with DRB1*1301 (OR 4.2, 95% CI 1.0-17.3), DPB1*0201 (OR 4.0, 95% CI 1.0-15.7) and DQB1*0603 (OR 11.5, 95% CI 2.5-53.4). Further analysis of the relative contributions of HLA antigens to ANA status revealed that DQB1*0603 determined the primary HLA effect. No apparent interaction between DQB1*0603 and DRB1*1301 or between DQB1*0603 and DPB1*0201 was found to contribute to the association with ANA. We suggest that those ANA positive individuals with a restricted HLA background, (DQB1*0603 positive), defines a group of EOPA-JCA patients which will be especially valuable in the characterization of the ANA associated with EOPA-JCA.

Objectives: To create an otolaryngology-specific needs assessment tool for shortterm global surgical trips and to describe our findings from its implementation.Methods: Surveys 1 and 2 were developed based on a literature review and disseminated to Low-Middle Income (LMIC) hosting institutions in Kenya and Ethiopia and to High-Income surgical trip participants (HIC), respectively. Respondents were otolaryngologists identified online, through professional organizations, and by word-ofmouth, who had participated in a surgical trip of <4 weeks.Results: HIC and LMIC respondents shared similar goals of expanding host surgical skills through education and training while building sustainable partnerships. Discrepancies were identified between LMIC desired surgical skills and supply needs and HIC current practices. Microvascular reconstruction (17.6%), advanced otologic surgery (17.6%), and FESS (14.7%) were most desired skills and high-demand equipment needs were FESS sets (89%), endoscopes (78%), and surgical drills (56%). Frequently taught techniques included advanced otologic surgery (36.6%), congenital anomaly surgery (14.6%), and FESS (14.6%) with the largest gap between LMIC-need and HIC-offerings being in microvascular reconstruction (17.6% vs. 0%). We also highlight the discrepancy in expectations of responsibility for trip logistics, research, and patient follow-up. Conclusion:We created and implemented the first otolaryngology-specific needs assessment tool in the literature. With its implementation in Ethiopia and Kenya, we were able to identify unmet needs as well as attitudes and perceptions of LMIC and HIC participants. This tool may be adapted and utilized to assess specific needs, resources, and goals of both host and visiting teams to facilitate successful global partnerships.
