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.  Two Unusual Gastrointestinal Foreign Bodies 
ISRN Surgery  2011;2011:187343.
Swallowed foreign bodies are common in the pediatric age group, but fortunately, the majority of them pass spontaneously without any adverse effects. Tube gastrostomy is an excellent method to provide prolonged enteral feeding. It is, however, associated with complications, namely, intraperitoneal leak and distal migration of the gastrostomy tube causing gastric outlet obstruction. This paper describes two unusual gastrointestinal foreign bodies, one was swallowed, while the other one was a complication of a tube gastrostomy.

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.

4.  Bleeding duodenal ulcer after Roux-en-Y gastric bypass surgery: the value of laparoscopic gastroduodenoscopy 
Annals of Saudi Medicine  2010;30(1):67-69.
Roux-en-Y gastric bypass is a common surgical procedure used to treat patients with morbid obesity. One of the rare, but potentially fatal complications of gastric bypass is upper gastrointestinal bleeding, which can pose diagnostic and therapeutic dilemmas. This report describes a 39-year-old male with morbid obesity who underwent a Roux-en-Y gastric bypass. Three months postoperatively, he sustained repeated and severe upper attacks of upper gastrointestinal bleeding. He received multiple blood transfusions, and had repeated upper and lower endoscopies with no diagnostic yield. Finally, he underwent laparoscopic endoscopy which revealed a bleeding duodenal ulcer. About 5 ml of saline with adrenaline was injected, followed by electrocoagulation to seal the overlying cleft and blood vessel. He was also treated with a course of a proton pump inhibitor and given treatment for H pylori eradication with no further attacks of bleeding. Taking in consideration the difficulties in accessing the bypassed stomach endoscopically, laparoscopic endoscopy is a feasible and valuable diagnostic and therapeutic procedure in patients who had gastric bypass.
