INTRODUCTION Primary hyperparathyroidism is a common endocrine disorder, with an incidence of 21.6 per 100,000 person-years. Asymptomatic elevated serum calcium levels on routine biochemical investigations accounts for 80% of newly diagnosed primary hyperparathyroidism. Solitary adenoma is the commonest cause of primary hyperparathyroidism and can be(More)
Groin pain post-total hip arthroplasty (THA) is of concern for the patient and the surgeon, especially when there is no history of any traumatic event. Obvious concern centres on complications from the prosthesis. The use of multiple imaging modalities allow for accurate diagnosis of groin pain. Atraumatic iliopsoas rupture is rare and has only been(More)
A heatstable alpha amylase gene was shotgun cloned from Bacillus licheniformis RPO1 into Bacillus subtilis. Restriction endonuclease analysis of the recombinant plasmid revealed a map which was identical to a previously cloned alpha amylase from B. licheniformis FDO2 and very similar to the restriction map of a high temperature amylase from Bacillus(More)
INTRODUCTION Resection of skin cancers of the conchal fossa and anti-helical rim presents a challenging reconstructive problem. A full thickness skin graft is often used following excision of the cartilage underlying the lesion. Colour mismatch, a contour defect and a donor site scar are potential drawbacks to this method of reconstruction. The(More)
BACKGROUND Pelvic and acetabular fractures are rare, complex injuries associated with significant morbidity. Fixation of these injuries requires major orthopaedic surgery which in itself is associated with substantial blood loss owing to the extensile operative approach and prolonged operating time required to address the complex fracture anatomy. In order(More)
BACKGROUND Tumour metastatic disease reflects a complex interplay between tumour characteristics and local host factors. This complex relationship may have an influence on the development of metastatic disease and patient survival. Multiple factors of the primary tumour influence the development of metastases and survival in patients. Breast cancer subtype(More)
INTRODUCTION Rectal adenocarcinoma typically metastasizes to the liver. When osseous spread occurs, it is most commonly detected in the vertebrae and pelvis. Distal osseous spread is unusual and may be the first presentation of the carcinoma. We present a review of the current literature on unusual osseous rectal adenocarcinoma metastases and highlight a(More)
Historically, a simple approach centered on palliation was applicable to the majority of patients with metastatic spinal disease. With advances in diagnosis and treatment, a more complicated algorithm has devolved requiring a multidisciplinary approach with institutional commitment and support. We performed a database review including pertinent articles(More)
BACKGROUND Heterotopic Ossification (HO) is a well-recognized complication following acetabular fracture fixation and its presence is prognostic for suboptimal clinical outcome. There are many controversies pertaining to its aetiology, including surgical approach, associated injuries and the use of HO prophylaxis. Long term data from high volume centres is(More)
Ring-fencing of elective orthopaedic beds has been shown to significantly reduce surgical site infection (SSI) rates. There are fewer studies in general surgical practice. Comparison of overall surgical workload in 2007 and 2011 was performed. Data pertaining to SSI were collected and analysis of this prospectively maintained database was performed on all(More)
