Pediatric Scurvy: When Contemporary Eating Habits Bring Back the Past.

Vitamin C deficiency is anecdotal in developed countries, mainly associated with underling clinical morbidities as autism or neurological impairment. Chronic insufficient dietary supply is responsible for vascular fragility and impaired bone formation, resulting in gingival bleeding, petechial lesions, articular and bone pain or limb swelling. Children may present anorexia, irritability, failure to thrive, limping or refusal to walk. Accordingly, pediatric scurvy is frequently misdiagnosed with osteomyelitis, septic arthritis, bone and soft tissue tumor, leukemia, bleeding disorders, and rheumatologic conditions. We report the case of a 3-years old child developing scurvy as consequence of strict selective diet; extensive and invasive investigations were undertaken before the correct diagnosis was considered. Despite being considered a rare condition, scurvy still exists nowadays, even in children with no apparent risk factors living in wealthy families. The increasing popularity of dietary restriction for children, especially those with allergies, may potentially enhance the occurrence of scurvy in apparently healthy children. Appropriate dietary anamnesis is fundamental in order to highlight potential nutritional deficit and to avoid unnecessary invasive diagnostic procedures. Patients without considerable risk factors may benefit from psychological support in order to investigate possible eating disorders.

Pediatric non alcoholic fatty liver disease: more on novel treatment targets.

The mainstay treatment of non alcoholic fatty liver disease (NAFLD) based on weight loss and/or lifestyle changes is most often unsuccessful at all ages, thus requiring the implementation of pharmacological strategies. Targeting insulin resistance and oxidative stress has recently proven unsatisfactory. Among a number of proposed innovative approaches targeting novel pathomechanisms, probiotics appear an interesting and reasonable option acting on gut-liver axis malfunction through the modulation of diet-driven, obesogenic, and inflammatory intestinal microbiota.A combined multiple pharmacological therapy directed simultaneously towards novel and old pathomechanisms (including, e.g., insulin resistance, oxidative stress, gut-liver axis, apoptosis) along with lifestyle interventions however might be necessary both in adult and pediatric NAFLD therapy.
