RESUMO
We report three cases of scurvy in previously healthy children referred to us for leg pain and refusal to walk. All children had no significant medical history, symptoms had started months before and subtly advanced. Two of them presented with gingival hyperplasia and petechiae, another one reported night sweats and gingival bleeding in the past few weeks. Two had vitamin D deficiency, and all had microcytic anaemia (in one case requiring transfusional support). A nutritional screening revealed low or undetectable levels of ascorbic acid. This, along with the clinical and radiological findings, led to a diagnosis of scurvy. Vitamin C supplementation was started with rapid improvement of the children's clinical condition. Scurvy is a rare disease in the 'first world', but there are anecdotal reports of scurvy in children without any of the known risk factors for this condition. In our cases, a selective diet was the only risk factor.

BACKGROUND: Vitamin K, a fat soluble vitamin, is a necessary cofactor for the activation of coagulation factors II, VII, IX, X, and protein C and S. In neonatal period, vitamin K deficiency may lead to Vitamin K Deficiency Bleeding (VKDB). CASE PRESENTATION: We present the case of a 2 months and 20 days Caucasian male, presented for bleeding from the injections sites of vaccines. At birth oral vitamin K prophylaxis was administered. Neonatal period was normal. He was exclusively breastfed and received a daily oral supplementation with 25 µg of vitamin K. A late onset vitamin K deficiency bleeding was suspected. Intravenous Vitamin K was administered with complete recovery. CONCLUSIONS: Nevertheless the oral prophylaxis, our case developed a VKDB: it is necessary to revise the current guidelines in order to standardize timing and dosage in different clinical conditions.
