1.  Strongyloides stercoralis hyperinfection in a post-renal transplant patient 
Strongyloides stercoralis is an intestinal nematode that is able to infect the host tissue and persist asymptomatic for many years through autoinfection. It causes life-threatening hyperinfection in immunocompromised hosts. This report describes a rare case of strongyloidiasis in a 40-year-old male following renal transplant, which was diagnosed by colonoscopic biopsy. The literature on the subject is also reviewed.

2.  Role of ERCP in the era of laparoscopic cholecystectomy for the evaluation of choledocholithiasis in sickle cell anemia 
AIM: To evaluate the role of endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis in patients with sickle cell anemia (SCA) in the era of laparoscopic cholecystectomy (LC).
METHODS: Two hundred and twenty four patients (144 male, 80 female; mean age, 22.4 years; range, 5-70 years) with SCA underwent ERCP as part of their evaluation for cholestatic jaundice (CJ). The indications for ERCP were: CJ only in 97, CJ and dilated bile ducts on ultrasound in 103, and CJ and common bile duct (CBD) stones on ultrasound in 42.
RESULTS: In total, CBD stones were found in 88 (39.3%) patients and there was evidence of recent stone passage in 16. Fifteen were post-LC patients. These had endoscopic sphincterotomy and stone extraction. The remaining 73 had endoscopic sphincterotomy and stone extraction followed by LC without an intraoperative cholangiogram.
CONCLUSION: In patients with SCA and cholelithiasis, ERCP is valuable whether preoperative or postoperative, and in none was there a need to perform intraoperative cholangiography. Sequential endoscopic sphincterotomy and stone extraction followed by LC is beneficial in these patients. Endoscopic sphincterotomy may also prove to be useful in these patients as it may prevent the future development of biliary sludge and bile duct stones.

3.  Thromboembolism in inflammatory bowel diseases: a report from Saudi Arabia 
Thromboembolism (TE) is a serious but under-recognized complication of inflammatory bowel disease (IBD). This is specially so in developing countries where the incidence of IBD is low. In Saudi Arabia, IBD is considered to be rare, but the incidence is increasing. Where the clinical manifestations resemble those of developed countries, TE as a complication of IBD is considered to be very rare. This report describes six IBD patients with TE. This importance of the complication of TE is stressed, and physicians caring for these patients should be aware of it in order to obviate potential morbidity and mortality.
