Osteogenesis imperfecta with bleeding diathesis.

Osteogenesis imperfecta (OI) is a disorder of type 1 collagen synthesis with varied complications in form of brittle bones, hearing loss, dental, skin, and ocular changes. Osteogenesis imperfecta may have bleeding diathesis rarely due to defective vascular integrity for the same reason. Here we come across a rare case of Sillence type IB Osteogenesis imperfecta with bleeding in the form of repeated epistaxis and petechial rash, which seem to have a collagenous link.

Cyanotic child--can it be methaemoglobinemia?

Methaemoglobinemia is a rare condition and can give surprise in emergency setup. We have encountered one such case in emergency recently that presented with both peripheral and central cyanosis without cardio-respiratory compromise. The patient was confirmed to be suffering from methaemoglobinemia due to antimalarials that he had received before coming to the hospital. Cyanosis due to methaemoglobinemia in our patient was precipitated by concomitant glucose 6-phosphate dehydrogenase (G6PD) deficiency. The patient was managed with conservative management and vitamin C administration.
