Perinatal-lethal Gaucher disease presenting with blueberry muffin lesions.

"Blueberry muffin baby" is an expression applied to newborns displaying a generalized purpuric rash caused by dermal erythropoiesis. This presentation is typically associated with TORCH (toxoplasmosis, other, rubella, cytomegalovirus, and herpesvirus) complex infections. However, alternative diagnoses should be considered, including other infections, neoplastic diseases, congenital vascular lesions, and metabolic diseases. We report a case of perinatal-lethal-type Gaucher disease presenting with cholestasis, hepatosplenomegaly, persistent thrombocytopenia, and blueberry muffin-like skin lesions.

Increased Relapse Rate During COVID-19 Lockdown in an Italian Cohort of Children With Juvenile Idiopathic Arthritis.

OBJECTIVE: Changes of routine disease management associated with COVID-19 lockdown might have potentially affected the clinical course of juvenile idiopathic arthritis (JIA). The aim of our study was to assess the rate of disease flare before and during COVID-19 lockdown to investigate its impact on disease course in children with JIA. METHODS: A single-center retrospective study was conducted, including patients presenting with inactive JIA between September 1, 2018 and March 9, 2019 (group A) and between September 1, 2019 and March 9, 2020 (group B). For each patient, demographic and clinical data were collected. The rate of JIA flare from March 10, 2019 to June 30, 2019 for group A and from March 10, 2020 to June 30, 2020 for group B was compared. RESULTS: Group A included 126 patients, and group B 124 patients. Statistical analysis did not show significant differences among the 2 cohorts with respect to age, sex, age at JIA onset, JIA subtype, co-occurrence of uveitis, antinuclear antibody positivity, and past or ongoing medications. The rate of disease flare during lockdown at the time of the first COVID-19 pandemic wave was significantly higher in comparison to the previous year (16.9% versus 6.3%; P = 0.009). CONCLUSION: Our study showed that COVID-19 lockdown was associated with a higher rate of joint inflammation in children with JIA. This finding has a considerable clinical implication, as restrictive measures may be necessary in order to contain pandemics. Our data highlight the need for rearrangement in the home and health care management of children with JIA during lockdowns.
