Helicobacter pylori and histopathological changes of gastric mucosa in Uganda population with varying prevalence of stomach cancer.
Study the pathological changes in gastric mucosa of Nyarwanda, Nkole (both with high prevalence of stomach cancer) and Ganda (with low prevalence of this cancer) ethnic groups in the presence of Helicobacter pylori (H. pylori) infection. ⋯ The major histological features relating stomach cancer to H. pylori in this study were presence of the infection in IM and GA that was observed mainly in Nyarwanda and Nkole. The lack of association between presence of lymphoid follicle and H. pylori infection probably explains the rarity of MALT lymphoma in Africa as these tumours are said to arise from H. pylori associated lymphoid follicles.

Case ReportsRuptured false iliac artery aneurysm--a case report from Nigeria.
A 23 year old male Nigerian presented to the Nephrology unit of the Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria with features of chronic renal failure secondary to chronic glomerulonephritis. He was referred to the surgical department of the hospital on account of severe torrential uncontrollable bleeding from an infected cannulation site. He was maintained on regular hemodialysis but developed femoral triangle sepsis at the cannulation site and aneurysm of the external iliac artery. ⋯ Exploration revealed a-4 cm rent in the external iliac artery that was sutured with 6/0 prolene, interrupted, using clamp and suture technique. Perfusion was satisfactory in the immediate post-operative period. The patient was transfused with 11 pints of blood within 12 hours and had an uneventful post-operative period.
