Hepatitis B virus infection amongst pregnant women in North-eastern Nigeria- a call for action.

BACKGROUND: It is well known that Hepatitis B virus infection is endemic in Nigeria. Even though studies have been carried out on Hepatitis B virus infection in different parts of Nigeria, and in different sub-groups of individuals, information regarding the prevalence of Hepatitis B virus infection in pregnant women is scanty especially from the North-eastern region of Nigeria. We therefore determined the seroprevalence of Hepatitis B surface antigen (HBsAg) amongst pregnant women in North Eastern Nigeria. MATERIALS AND METHODS: A hospital-based cross-sectional study was carried out. The setting was the ante-natal clinic of the Federal Medical Centre, Yola, Nigeria. The duration of the study was from July 2008 to December 2008. Two hundred and thirty-one consecutively recruited pregnant women were screened for Hepatitis B surface antigen. Positive samples were re-tested using ELISA to eliminate false positives. Their biodata were obtained using a questionnaire to establish the presence of possible risk factors such as blood transfusion, surgery, etc. Written informed consent was obtained from each woman. RESULTS: Out of the 231 pregnant women tested, nineteen of them were seropositive for Hepatitis B virus infection giving an infection rate of 8.2%. Women in the age group 25-29 years had the highest HBV infection rate. CONCLUSION: This study confirms a high seroprevalence of Hepatitis B virus infect ion amongst pregnant women. It is recommended that pregnant women should be routinely screened for Hepatitis B virus infection as part of antenatal care services.

Upper gastrointestinal tract bleeding in Ilorin, Nigeria--a report of 30 cases.

BACKGROUND: Upper gastrointestinal tract bleeding refers to blood loss within the intraluminal gastrointestinal tract from any location between the upper oesophagus to the duodenum at the ligament of Treitz. The onset and severity of blood loss varies widely. Acute gastrointestinal bleeding is a potentially life-threatening abdominal emergency that remains a common cause of hospitalization. There is no local data on the clinical presentation, endoscopic findings and the risk factors for upper gastrointestinal tract bleeding in Ilorin. This study was therefore to review the cases of upper gastrointestinal tract bleed in Ilorin. AIM: To review the cases of upper gastrointestinal tract bleeding seen in Ilorin. METHODOLOGY: A retrospective review of the cases of upper gastrointestinal tract bleeding who had upper gastrointestinal tract endoscopy as part of their workup was undertaken to cover a eighteen month period from June 2006 to November 2007. Their clinical presentation, endoscopic findings, and the risk factors which predisposed them to bleeding were evaluated. The endoscopy register and the request forms were reviewed. RESULTS: A total of thirty patients had upper gastrointestinal tract bleeding for which upper gastrointestinal tract endoscopy was performed during the period under review. Twenty-three of the patients were males (76.7%) while seven were females (23.3%). Sixteen patients (53.3%) presented with malaena only; eleven patients (36.7%) with malaena and haematemesis only; while three patients (10.0%) presented with malaena, haematemesis and haematochexia. However all the patients presented with malaena, haematemesis or haematochexia. The commonest clinical presentation of patients with upper gastrointestinal tract bleeding passage of malaena (53.3%). The commonest endoscopic finding was multiple sources of bleeding (66.7%) while the commonest risk factor for upper gastrointestinal tract bleeding was NSAID use (36.7%). CONCLUSION: The passage of malaena, multiple source of bleeding, and NSAID use are the commonest clinical presentation, endoscopic findings and risk factors respectively in patients with upper gastrointestinal tract bleeding in Ilorin. The spectrum of clinical presentation, endoscopic findings and risk factors for upper gastrointestinal tract bleed found in this study is similar to that found by other workers.

Upper gastrointestinal tract endoscopy indications in northern Nigeria.

Upper gastrointestinal tract endoscopy is one of the commonly performed endoscopic procedures, and has only recently become available in Nigeria. The indications for upper gastrointestinal tract endoscopy in three health facilities in Northern Nigeria were reviewed. Two hundred and sixty-nine patients were found to have undergone upper gastrointestinal tract endoscopy. Their ages ranged from 12-90 years with a mean of 48.1+16.2 years. There were 46.8% males and 53.2% females. The commonest indication for the procedure was dyspepsia (61.0%), followed by upper gastrointestinal bleeding, gastro-oesophageal reflux disease, gastric cancer, gastric outlet obstruction, acute exacerbation of peptic ulcer disease, dysphagia, epigastric mass, excessive salivation, abdominal pain, anaemia, chronic diarrhoea, haematochexia and persistent vomiting.

The relationship between gallstone disease and gall bladder volume.

BACKGROUND: The role of a large gallbladder volume with regards to a predisposition to gallstones is unknown. It is likely that an increase in gallbladder volume could result in impaired gallbladder motility and bile stasis which may encourage gallstone formation. This study is therefore to determine the relationship between the presence of gallstone disease and gall bladder volume. METHODOLOGY: One hundred type 2 diabetic patients and 100 age and sex-matched controls underwent real time ultrasonography to determine the relationship between the presence of gallstone disease and gallbladder volume. Their demographic characteristics were recorded and compared. The ultrasound examinations was done in the morning following an overnight fast (to prevent gall bladder contraction) without sedation. Longitudinal and transverse scans of the right upper quadrant was done in both the supine and left lateral positions The gallbladder volume was measured. RESULT: The mean gallbladder volume in diabetic patients with gallstone disease 28.4 +/- 18.6 ml was higher than in those without gallstone disease 27.4 +/- 14.8 ml p = 0.844. The mean gallbladder volume in the controls with gallstone disease 26.5 +/- 14.7 ml was also higher than in those without gallstone disease 24.1 +/- 12.7 ml p = 0.189. CONCLUSION: The fasting gallbladder volume tended to be larger in patients with gallstones (i.e. both diabetic patients and controls).
