Sinus pericranii: long-term outcome in a 10-year-old boy with a review of literature.

Sinus pericranii is a rare cranial venous anomaly in which there is an abnormal communication between intracranial dural sinuses and extracranial venous structures, usually via an emissary transosseous vein. We report the case of a 10-year-old boy who was successfully managed conservatively. The clinical findings, investigations and management are discussed. We focus on the long-term management of these patients, with a review of the relevant literature.

Rare progression of cholangiocarcinoma: distal femoral metastasis.

Cholangiocarcinoma (CCA) is a rare cancer of the bile duct epithelial cells, with metastases to long bones rarely reported. We present the case of a woman aged 61 years, diagnosed with CCA 6 years previously. She presented with right thigh discomfort, rapidly progressing to immobility with severe pain. Radiological investigations revealed a lytic lesion in her right distal femur, most likely a metastatic deposit, at high risk of pathological fracture. This was managed with an en bloc resection and implantation of a distal femoral replacement. Pathology specimens from theatre confirmed metastatic CCA. Despite sustaining a subsequent fractured neck of femur on the operative side, she recovered well from surgery, with minimal pain and improved mobility on discharge. She restarted palliative chemotherapy. This case illustrates the option of definitive major surgery for the management of metastatic bone disease. As in this case, this can lead to improved symptom control and quality of remaining life.

Cognitive outcome after on- and off-pump coronary artery bypass grafting surgery: a systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to compare cognition following coronary artery bypass grafting (CABG) surgery with or without cardiopulmonary bypass (CPB) (on- or off-pump). DESIGN: Systematic review and meta-analysis of randomized control trials comparing cognitive outcome in patients undergoing CABG surgery on- or off-pump as assessed by continuous measures from a battery of 7 psychometric tests. SETTING: Multi-institutional centers performing CABG surgery. PARTICIPANTS: Patients with coronary artery disease requiring CABG surgery. INTERVENTIONS: CABG surgery with or without CPB. MEASUREMENTS AND MAIN RESULTS: A structured literature search identified 13 randomized control trials that included a total of 2,405 patients. Results from 7 psychometric tests were grouped into early (≤3 months) and late (6-12 months) postoperative periods. No significant differences were found between on- and off-pump groups in any of the 7 psychometric tests in either the early (p range 0.21-0.78) or late (p range 0.09-0.93) postoperative period. CONCLUSION: The results suggested that CPB may not be associated with cognitive decline that is associated with CABG surgery.
