Key Clinical MessageIntravesical instillation of Bacillus Calmette‐Guérin (BCG) has been shown to be an effective form of immunotherapy for bladder cancer. This case report describes a patient who develops systemic BCG‐osis following intravesical BCG instillation and demonstrates the importance of being aware of more severe complications associated with BCG immunotherapy.

Introduction: Osteoporotic acetabular fractures are common and pose a difficult technical challenge for the trauma surgeon. Acute total hip arthroplasty (THA) using a Burch-Schneider antiprotrusio cage with immediate postoperative weight-bearing is a method to approach these injuries. This case series reports our outcomes of acute THA using Burch-Schneider cages for acetabular fractures from a UK major trauma centre based on length of stay, radiological outcome, complications and outcome scores. Methods: Data were collected from all patients who underwent acute THA with a Burch-Schneider cage for acetabular fractures between June 2006 and August 2015. Patients were followed up clinically, radiologically, and using Oxford Hip Scores (OHS). Results: 20 patients with a median age of 73 (range 60–90 years) were identified. All patients were independent walkers at follow-up, and had achieved radiological union. There were no dislocations, subsidence, revision or deep infections. Significant complications include 1 perioperative death as a result of complications arising from pre-existing pulmonary fibrosis; 1 deep vein thrombosis; 1 intraoperative arterial injury to the superior gluteal artery; and 1 leg-length discrepancy. Mean length of stay was 10 days. The mean OHS was 37/48 at a mean follow-up of 26 months. Conclusions: This case series further validates the use of Burch-Schneider cages with primary THA in acute acetabular fractures.

Background:Diabetic peripheral neuropathy puts patients at increased risk of acute injury by foreign bodies and also contributes to delayed presentation and diagnosis.Case report:We describe a 57-year-old patient with poorly controlled type 1 diabetes who presented with a three-week history of worsening swelling and erythema in the metacarpophalangeal joint of his left thumb. He denied any previous trauma or injury and was initially treated with intravenous antibiotics. Subsequent imaging revealed septic arthritis and osteomyelitis secondary to a retained foreign body, which was surgically removed in theatre.Conclusion:This is the first reported case of a retained foreign body in the hand of a diabetic patient, and demonstrates the importance of early radiological imaging of peripheral limb injuries in high-risk patients.
