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.WHAT'S KNOWN ON THIS SUBJECT: StevensJohnson syndrome (SJS) is a rare and severe immunologic phenomenon characterized by rash and mucous membrane disease. SJS may be triggered by medications and, less commonly, by infections such as Mycoplasma pneumoniae (Mp). Outbreaks of SJS are exceedingly rare. WHAT THIS STUDY ADDS:We describe the largest SJS outbreak reported in children, which was also Mp-associated. In the first case-control study of this disease, we identify predictors of Mp-associated SJS versus non-Mp-associated SJS, including fewer skin lesions, pneumonia, and elevated erythrocyte sedimentation rate.

An outbreak of eighteen cases of pemphigus neonatorum in a maternity department is described.Strains ofStaph. aureusisolated from the infants, the mothers and the staff during several weeks of intensive investigations were classified by phage typing.The findings indicated that, during the latter part of the outbreak at least, the adults were not the source of infection.There was evidence of wide dissemination of the epidemic strain ofStaph. aureusamong the healthy infants in the nursery. It is suggested that the main path of infection was from infant to infant.Methods of controlling established outbreaks are discussed.

Background: Psychiatric inpatient treatment for children is sometimes beneficial, but predictors of who benefits, and in what circumstances, are largely unknown. This study aimed to identify personal and environmental factors that influence outcome in an adolescent unit that accepts both emergency and planned admissions. Methods: Routine standardised intake and outcome measures were analysed for the period 2009–2018. Potential predictors assessed included the Children’s Global Assessment Scale (CGAS), engagement with treatment, behavioural attitudes and peer relationships on the unit. Findings: One hundred and twelve admissions were tracked. Mean age of admission was 16 years, and 71% were female. A total of 61% had higher (better) CGAS scores on discharge than on admission; 34% of inpatients fully engaged with their treatment. Median admission duration was 118 days for males and 196 days for females. Admission lengths were much shorter for ethnic minority patients, but group sizes were small. Longer admissions led to greater improvement. Poor outcomes were associated with failure to engage with treatment and a deterioration in peer relationships. Interpretation: Compliance with treatment and female gender were both significant predictors of positive change during admission. The establishment of good and supportive peer relationships during the admission was also a potent indicator of benefit.
