Investigation of primary immune deficiency after severe bacterial infection in children: A population-based study in western France.

Background: Infectious diseases are still an important cause of morbidity and mortality in high-income countries and may preferentially affect predisposed children, especially immunocompromised children. We aimed to evaluate the frequency of recommended immunological tests in children with community-onset severe bacterial infection (COSBI) admitted to a pediatric intensive care unit. We also assessed the frequency and described the typology of diagnosed primary immune deficiency (PID).

Prevalence of acid gastroesophageal reflux disease in infants with esophageal atresia/tracheoesophageal fistula.

Background: Given the high prevalence and complication risks of acid gastroesophageal reflux (GERD) in the first months of life in infants with esophageal atresia, the ESPGHAN/NASPGHAN consensus statement recommends systematic treatment with proton pump inhibitors (PPIs) until the age of 1 year and checking for acid GERD thereafter. However, these recommendations have not been evaluated.

Methods: This prospective study was conducted from 2007 to 2016.

[From human pluripotent stem cells to custom-made intestinal organoids].

The study of gut diseases is often limited by the access to human biological tissues and animal models that do not faithfully mimic the human pathologies. In this context, the development of intestinal organoids from human pluripotent stem cells is paving the way of gastrointestinal physiology and digestive disease study. In this review, we recall the embryonic development of the digestive tract and its translation to human pluripotent stem cell differentiation.

[DRESS complicated by hemophagocytic lymphohistiocytosis in an infant treated for congenital toxoplasmosis].

Background: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe disease that may be complicated by hemophagocytic lymphohistiocytosis but this is rarely described in children.

Patients And Methods: We report the case of a 5-week old infant hospitalized in a pediatric intensive care unit for hemophagocytic lymphohistiocytosis with prolonged fever, splenomegaly, cytopenia, fibrinogen≤1.5g/L, ferritin≥500μg/L, and soluble IL-2 receptor≥2400U/mL.

[Acute leukemia revealed by bone magnetic resonance imaging: Two pediatric case reports].

Bone and joint pain are common causes of pediatric consultation for a variety of etiologies. The causes are mostly traumatic or infectious or have an inflammatory origin. Acute leukemia (AL) can sometimes begin with osteoarticular signs and radiological investigations such as magnetic resonance imaging (MRI) can help guide the diagnosis.
