ABSTRACT
BACKGROUND: Multiple myeloma (MM) in Hispanics has never been studied. We therefore sought to determine the clinical characteristics and overall survival in MM of Hispanics compared to non-Hispanic whites (NHW) and non-Hispanic blacks (NHB). PATIENTS AND METHODS: A single-center analysis of 939 patients diagnosed with MM from 2000 to 2017 with a large representation of NHB (n = 489), Hispanics (n = 281), and NHW (n = 169) was conducted to evaluate outcomes and disease characteristics. We used the Connect MM Registry, a large US multicenter prospective observational study with newly diagnosed MM patients, as a validation cohort. RESULTS: Hispanics had a higher incidence of MM compared to NHW. The median age at presentation was 5 years younger (median, 65 years) in Hispanics compared to NHW (median, 70 years), and patients were more likely to present with renal dysfunction (estimated glomerular filtration rate < 30 mL/min). Hispanics had a higher proportion of Revised International Staging System (R-ISS) stage I disease compared to NHW and NHB (P = .03), while there was no difference in cytogenetics between Hispanics and NHB/NHW. In the multivariate analysis, only high-risk disease and response to first-line therapy significantly affected survival. CONCLUSION: In this first and largest analysis of MM in Hispanics, we found that Hispanics present at a younger age, have a higher incidence of renal dysfunction, and have low R-ISS stage disease at presentation. With equal access to therapy, Hispanics have survival similar to NHW/NHB.

Primary hyperhidrosis is a common disorder affecting children and adolescents, and it can have a significant negative psychosocial effect. Treatment for pediatric hyperhidrosis tends to be limited by low efficacy, low adherence, and poor tolerance. Oral glycopyrrolate is emerging as a potential second-line treatment option, but experience with safety, efficacy, and dosing is especially limited in children. We present an institutional review of 12 children with severe, refractory hyperhidrosis treated with oral glycopyrrolate; 11 (92%) noted improvement and 9 (75%) would recommend oral glycopyrrolate to their friends. No significant side effects were noted. Our retrospective analysis suggests that oral glycopyrrolate is safe and effective in children with hyperhidrosis.
