Objectives: To investigate the causes of lower gastrointestinal bleeding (LGIB) in Yemeni patients and to compare our results with the results of other studies. Design: Prospective study of patients with overt LGIB during the period from April 2017 to March 2018. Setting: Specialized center of gastrointestinal and liver diseases in Ibb city, Yemen. Subjects & Method: Consecutive patients who presented or referred to our center with LGIB to whom lower GI endoscopy was performed. Results: During the study period, we had 122 patients with LGIB, 72 were males and 50 were females, with male:female ratio of 1.4:1 The age ranged between 5 and 82 years and the mean age was 45 ± 17.99 years. The clinical presentations of our patients included hematochezia in 72.1%, abdominal pain in 51.7%, diarrhea in 43.3%, pallor, and anemia in 40.2%, weight loss in 39.3%, constipation in 16.4%, bloody diarrhea in 16.4%, and melena in 5.7%. The most common colonoscopic findings were hemorrhoids in 36.7% followed by colon cancer in 19.7% and nonspecific colitis in 15.6%. Conclusion: Hemorrhoids and colon cancer were the most common causes of lower GI bleeding in our patients.

Objectives: To study the clinicopathological pattern of gastric cancer in-cluding the location of the tumor in the stomach and to compare our results with other studies. Design: Prospective study of patients confirmed with gastric malignancy during the period from July 2016 to July 2017. Setting: Specialized center of gastrointestinal and liver diseases in Ibb city, Yemen. Subjects: All patients with histopathological confirmation of gastric malig-nancy. Results: During the study period, we had 69 patients with gastric cancer; among them 48 were males and 21 were females, with male: Female ratio is 2.2:1. The age ranged between 35 years and 90 years and the mean age was 65.87 ± 12.79 years. Most of the patients presented with epigastric pain (87%), weight loss (72.5%), pallor (65.2%), dysphagia (47.8%), vomiting (42%), palpable epigastric mass (20.3%) and hematemesis/melena (18.8%). The cardiofundal location was encountered in 33 cases (47.8% ), 22 (45.8%) males and 11 (52.4%) females, the corpus location in 24 cases (26%), 20 (41.7%) males and 4 (19%) females, the antral location in 8 cases (11.6%), 4 (8.3%) males and 4 (19%) females and the whole stomach in 4 cases (5.8%), 2 (4.2%) males and 2 (9.5%) females. Adenocarcinoma constituted about 94.2%, of which the intestinal type was 87.5% and the diffuse type was 12.5%. The non-epithelial tumor was encounter 4.3%, of which 2.9% were lymphoma and 1.4% were GIST. Conclusion: In our studied patients, proximally located gastric cancer was the most common in both sexes.

Abstract: The feasibility of utilizing soybean-processing residues such as soybean meal and hulls as substrates for chitosan production by the fungus Mucor rouxii ATCC 24905 via solid-state fermentation (SSF) was investigated. The effects of the type of soybean-based substrate, length of cultivation period, substrate moisture content, substrate pH, incubation temperature and extraction conditions on chitosan yield were determined. The results showed that a maximum fungal chitosan yield of up to 3.44% by dry substrate weight (34.4 g/kg) could be achieved using a pure soybean meal substrate with an initial moisture content of 50% (w/w) and pH of 5 - 6 incubated for six days at 25°C. A more severe heat treatment (autoclaving vs. refluxing) resulted in higher chitosan extraction yields regardless of the strength of extraction reagents. Fourier transform infrared (FTIR) analysis of the fungal chitosan revealed its degree of deacetylation (DDA) to be between 55% and 60%.
