Choledochal cysts, although more common in females than males, have only rarely been encountered in association with pregnancy. We report a patient with a large choledochal cyst that was excised at the time of cesarean section. Pathologically, the cyst wall was found to contain a focus of adenocarcinoma. The development of carcinoma is a recognized risk in(More)
Clinical staging is woefully inadequate in predicting lymph node metastasis and dictating prudent radiation ports in women undergoing therapy for cervical malignancies. Surgical staging with evaluation of the precaval lymph nodes (via a transperitoneal or extraperitoneal approach) has associated rates of complication that are felt by many clinicians to be(More)
Allogenic blood is a finite resource, with associated risks. Previous studies show intraoperative cell salvage (ICS) can reduce allogenic transfusion rates in orthopaedic surgery. However, there are concerns regarding efficacy and cost-effectiveness of ICS. This study was carried out to review ICS use in revision hip arthroplasty. All patients who underwent(More)
Software estimation accuracy is one of the most difficult tasks for software developers. Defining the project estimated cost, duration and maintenance effort early in the development life cycle is greatest challenge to be achieved for software projects. Formal effort estimation models, like Constructive Cost Model (COCOMO) are limited by their inability to(More)
A case is reported of traumatic cyst lying in the molar region of the mandible. It extended to the inferior border of the mandible and extended the buccal alveolar bone. The cystic cavity contained the inferior neuro-vascular bundle yellow serous fluid, and a small amount of gas. The wall of the cavity was lined with loosely arranged connective tissue with(More)
A case in reported of coincidental abnormalities of development of both the premaxilla and anterior mandible. The defect in the mandible presented certain radiographic features frequently observed in cystic or neoplastic lesions. Histological examination revealed it to be of a developmental nature. The importance of adequate examination of tissue removed(More)
