Severe hypercalcemia due to subcutaneous fat necrosis despite minimal skin lesions in a newborn: a case report

Berkenbosch Lizanne , Straetemans Saartje

Introduction: Subcutaneous fat necrosis of the newborn (SCFN) is a self-limiting panniculitis which can develop in the first weeks of life. The disorder is characterized by firm, red or purple subcutaneous nodules and plaques on the trunk, buttocks, cheeks, and extremities and is associated with perinatal stress. SCFN may lead to hypoglycemia, anemia, thrombocytopenia, hypertriglyceridemia and hypercalcemia. The proposed mechanism for the hypercalcemia is extr...

Introduction: Among children with short stature, some show persistent IGF-I levels <-2.0 SDS despite a normal growth hormone (GH) response in a stimulation test. This may be caused by conditions that could benefit from recombinant human GH (rhGH) therapy (e.g. GH neurosecretory dysfunction, bioinactive GH, partial GH insensitivity). Therefore, the IGF-I generation test (IGFIGT) was implemented in 2006 using a national, standardized protocol. Children with a...
