Role of isolated percutaneous autologous platelet concentrate in delayed union of long bones.

Purpose: The objective of this study is to evaluate the efficacy of percutaneous platelet concentrate (PC) injection in increasing the chances of attaining union in delayed union of long bones and to know whether the time taken for union decreases with use of PC.

Methods: Forty delayed unions (15-30 weeks old) were randomized into a study group in which autologous PC prepared by blood bank centrifuge was percutaneously injected at the fracture site under image intensifier after activation with 10% calcium gluconate and a control group where patients were observed over time. Follow-up was every 6 weeks till fracture union.

Brodie's abscess of the posterior ilium: a rare cause for low back pain in children.

Brodie's abscess of the pelvis is very rare in healthy children. It can be missed because of its varied presentation. We present an 11-year-old boy who presented with low back pain.

Congenital insensitivity to pain and anhydrosis: a report of two cases.

We report on 2 patients with congenital insensitivity to pain and anhydrosis. The first one was a 7-month-old boy who presented with non-traumatic, haematogenous septic dislocation of the right elbow with physeal separation of the distal humerus. The second one was a 3-year-old girl suspected to have Job syndrome with an altered immunological profile.

Osteomyelitis and pyomyositis due to Pseudomonas aeruginosa in a child with sickle β⁰-thalassemia.

Sickle cell osteomyelitis is usually due to Salmonella or Staphylococcal etiology. Pseudomonas as a cause of sickle cell osteomyelitis is rare. Similarly, pyomyositis is a rare complication in children with sickle cell disease and few cases have been reported, predominantly due to Staphylococcus.
