SRC and MA demonstrate clinicopathologic characteristics suggestive of a different biology compared with OA. In our dataset, SRC has a significantly poorer CSS whereas survival rates for MA are similar to OA. These characteristics are similar in both Asian and Western studies reported. Asian reports however suggest a lower incidence of MA.

To assess the awareness and acceptability of colorectal cancer (CRC) screening in noncompliant Singaporeans and to determine if their barriers can be overcome by education. A questionnaire developed from thematic analysis of open-ended interviews with 72 subjects was administered to 580 residents in a local high-rise housing estate. Participants aware of CRC screening were assessed for barriers and acceptability of CRC screening. All participants were subsequently educated about CRC screening and reassessed for barriers and acceptance. Those keen for fecal occult blood testing (FOBT) were offered FOBT kits and followed up. CRC screening awareness was poor. Having no symptoms was the most common barrier. More barriers to FOBT than to colonoscopy were reduced with education. After education, acceptability toward FOBT increased but rejection rates rose even higher. FOBT is probably Singapore's most acceptable screening modality. Education is limited by barriers, which need to be overcome by alternative measures.

Background: Peritoneal dialysis catheter (PDC)-related infections account for significant morbidity, PD disruptions and costs. Patients with refractory exit-site or tunnel track infections without peritonitis may need catheter removal and reinsertion which can be complicated by bleeding, organ injury, catheter failure or malposition. Some patients may need to switch to haemodialysis in such a setting. An alternative is a salvage procedure. The purpose of this systematic review is to evaluate the safety and efficacy of salvage techniques. Methods: A comprehensive search of PubMed, Medline and Scopus databases was performed from inception to December 2021 in accordance with PRISMA guidelines. After a broad search, articles were stratified into two main categories for assessment: (1) cuff-shaving (CS) techniques and its variations of en-bloc resection (BR) and/or catheter diversion (CD) and (2) partial reimplantation with CD. Results: A total of 409 patients (445 salvage procedures) from 20 studies were included in analysis. Of 409 patients, 234 patients (57.2%) underwent 251 (56.4%) CS procedures and its variations, 163 patients (39.9%) underwent 182 (40.9%) partial PDC reimplantations with CD and 12 patients (2.7%) underwent local curettage. Overall PDC salvage rate after intervention was 73.2%. Overall PDC removal rate attributable to infection was 26.8%. Overall complication rate attributable to the procedures was 2.7%, with the most common complication being dialysate leakage ( n = 10) followed by PDC laceration ( n = 1) and subcutaneous haematoma ( n = 1). We also included a description of our technique of BR of infected tissue, CS and CD. In a series of six patients, the PDC salvage rate was 83.3% and median PDC survival after intervention was 10 months. Conclusion: PDC salvage techniques are relatively safe and provide reasonable catheter salvage rates in selected patients. Results of this review should lend weight to consideration of a salvage-first approach as an option in selected patients.

Aortic aneurysms are a rare cardiovascular complication of Systemic Lupus Erythromatosus (SLE) and the true incidence is unknown. This case report shares our experience with a 40 year old lady suffering from SLE whose Abdominal Aortic Aneurysm (AAA) was treated successfully with endovascular aneurysm repair (EVAR). To the author's knowledge, the use of EVAR for AAA in SLE patients has not been reported in available literature. The pathogenesis and differences in aneurysmal disease in patients with SLE is also discussed.
