BACKGROUND: Stevens-Johnson syndrome (SJS) is an uncommon, sporadic disease and outbreaks are rare. In November 2013, an outbreak of SJS was identified at Children’s Hospital Colorado. METHODS: Outbreak cases were children aged 5–21 with a discharge diagnosis of SJS admitted from September 1 to November 30, 2013. Medical charts were reviewed using standardized data collection forms. Respiratory specimens were tested for viruses and Mycoplasma pneumoniae (Mp) by polymerase chain reaction (PCR). We conducted a separate 4-year retrospective case-control study comparing hospitalized SJS cases with and without evidence of Mp infection. RESULTS: During the outbreak, 8 children met SJS criteria. Median age was 11.5 years (range 8–16 years); 5 (63%) were boys and 5 (63%) were Mp-PCR–positive. Of the 5 PCR-positive children, none had preceding medication exposure, and all had radiographic pneumonia. All outbreak Mp isolates were macrolide susceptible. The retrospective case-control analysis showed that Mp-associated SJS episodes (n = 17) were more likely to have pneumonia (odds ratio [OR] 10.0, confidence interval [CI] 1.3–5.1), preceding respiratory symptoms (OR 30.0, CI 1.6–72.6), an erythrocyte sedimentation rate ≥35 mg/dL (OR 22.8, CI 2.1–244.9), and ≤3 affected skin sites (OR 4.5, CI 1.2–17.4) than non–Mp-associated SJS episodes (n = 23). CONCLUSIONS: We report the largest outbreak of SJS in children, which was also predominately associated with Mp infection. Mp-associated SJS was associated with a distinct clinical presentation that included less extensive skin disease, an elevated erythrocyte sedimentation rate, and evidence of a preceding respiratory infection.

Objective: We aimed to improve paediatric inpatient surveillance at a busy referral hospital in Malawi with two new programmes: (i) the provision of vital sign equipment and implementation of an inpatient triage programme (ITAT) that includes a simplified paediatric severity‐of‐illness score, and (ii) task shifting ITAT to a new cadre of healthcare workers called ‘vital sign assistants’ (VSAs).Methods: This study, conducted on the paediatric inpatient ward of a large referral hospital in Malawi, was divided into three phases, each lasting 4 weeks. In Phase A, we collected baseline data. In Phase B, we provided three new automated vital sign poles and implemented ITAT with current hospital staff. In Phase C, VSAs were introduced and performed ITAT. Our primary outcome measures were the number of vital sign assessments performed and clinician notifications to reassess patients with high ITAT scores.Results: We enrolled 3994 patients who received 5155 vital sign assessments. Assessment frequency was equal between Phases A (0.67 assessments/patient) and B (0.61 assessments/patient), but increased 3.6‐fold in Phase C (2.44 assessments/patient, P < 0.001). Clinician notifications increased from Phases A (84) and B (113) to Phase C (161, P = 0.002). Inpatient mortality fell from Phase A (9.3%) to Phases B (5.7) and C (6.9%).Conclusion: ITAT with VSAs improved vital sign assessments and nearly doubled clinician notifications of patients needing further assessment due to high ITAT scores, while equipment alone made no difference. Task shifting ITAT to VSAs may improve outcomes in paediatric hospitals in the developing world.

We performed a retrospective chart review for all cases of recurrent Stevens Johnson Syndrome (SJS) from March 2013 to March 2016. Nine children had 29 episodes of SJS or incomplete SJS; all children were male and 8 (88%) were white. Episodes affected mucus membranes with minimal skin involvement. Mycoplasma infections and HLA-B27/-B51 were common.

: Each year in Latin America and the Caribbean, seasonal influenza is associated with an estimated 36,500 respiratory deaths and 400,000 hospitalizations. Since the 2009 influenza A(H1N1) pandemic, the Region has made significant advances in the prevention and control of seasonal influenza, including improved surveillance systems, burden estimates, and vaccination of at-risk groups. The Global Influenza Strategy 2019–2030 provides a framework to strengthen these advances. Against the backdrop of this new framework, the University of Colorado convened in October 2020 its Immunization Advisory Group of Experts to review and discuss current surveillance, prevention, and control strategies for seasonal influenza in Latin America and the Caribbean, also in the context of the COVID-19 pandemic. This review identified five areas for action and made recommendations specific to each area. The Region should continue its efforts to strengthen surveillance and impact evaluations. Existing data on disease burden, seasonality patterns, and vaccination effectiveness should be used to inform decision-making at the country level as well as advocacy efforts for programmatic resources. Regional and country strategic plans should be prepared and include specific targets for 2030. Existing investments in influenza prevention and control, including for immunization programs, should be optimized. Finally, regional partnerships, such as the regional networks for syndromic surveillance and vaccine effectiveness evaluation (SARInet and REVELAC-i), should continue to play a critical role in continuous learning and standardization by sharing experiences and best practices among countries.
