RESUMO
BACKGROUND: Helicobacter pylori is the most common chronic bacterial infection, and a significant aetiological factor in acid peptic diseases and gastric cancer. Dyspepsia is a common gastrointestinal disorder, and the most common indication for gastroscopy. Detection of this organism during endoscopy has become standard clinical practice. We determine the prevalence of H. pylori infection among dyspeptic patients using serology and histology. METHODS: Patients with dyspepsia underwent gastroscopy, and biopsies were taken from the antral portions of their stomach and processed. Their serum samples were tested for H. pylori infection using ELISA to detect anti-bodies. RESULTS: One hundred and twenty-five patients, comprising 49 (39.2%) males and 76 (60.8%) females were studied. A prevalence rate of 93.6% for H. pylori was found by serology while a rate of 80.0% was found by histology. CONCLUSION: There is a high prevalence of H. pylori infection in patients with dyspepsia; and a high percentage of detection by serological and histological tests.

The prevalence of community-acquired meticillin resistant Staphylococcus aureus (ca-MRSA) as an important cause of hand infections has gained much recognition. The clinical impact of this is less well documented in the United Kingdom. This study looks at the incidence of hand infections in an urban Scottish teaching hospital over a 12 month period.

Chronic hepatitis C1 is a common cause of liver disease worldwide. It is a slow and progressive condition which can lead to decompensated cirrhosis and hepatocellular carcinoma. Hepatitis C virus1 impairs quality of life (QOL) even in the absence of chronic liver disease, but its relative silent nature can lead to a delay in diagnosis. The current standard of care of treatment is pegylated interferon and ribavarin. This achieves a sustained virological response (SVR), which is a cure of infection, in up to 80% of patients depending on viral genotype. The attainment of SVR improves survival, avoids long-term complications, and improves QOL. But treatment is not only expensive; there are issues of tolerability and adverse effects. This has led to a multitude of cost effective analysis and health technology assessment on HCV treatment. This overview discusses the natural history of the virus infection and its effect on the patients' QOL. It focuses on the treatment options available, their efficacy, and cost effectiveness. It reviews the evaluations that suggest combination therapy is cost effective and explores the assumptions and limitations of these studies in real world treatment arenas.
RESUMO
The human immunodeficiency virus (HIV) infection has been shown to be a risk factor for premalignant and malignant conditions of the cervix. Patients attending the gynaecological clinic of the University of Maiduguri Teaching Hospital received voluntary counselling and testing (VCT) for HIV. All patients who were screened for HIV also had their pap smear taken. Cervical dysplasia was significantly commoner among HIV infected women than those that were HIV negative (31.3% vs 7.8%, respectively). The incidence of cervical dysplasia was also proportional to the degree of immunosuppression as women with low CD4 count had higher incidence of cervical dysplasia. The population studied was generally promiscuous irrespective of their HIV status, with over 90% of them having multiple sexual partners. It is recommended that health education in this population should be aimed at discouraging multiple sexual partners. Gynaecologists should be co-care providers to all HIV+ women in view of the menace of cervical dysplasia.

The study is aimed at classifying liver diseases diagnosed by fine needle aspiration cytology (FNAC) in our environment and to emphasize the importance of the procedure for management of our patients. Forty-two patients were referred by the physicians for fine needle aspiration cytology diagnosis in Histopathology Department, University of Maiduguri Teaching Hospital between January 2001 and December 2003. There were 30 males and 12 females (2.5:1) with mean age of 44.7 years. The peak age is in the 5th decade of life. The commonest hepatic disease is primary hepatic malignancy, which accounted for 78.6% (33 patients); 3 suspicious of malignancy, one case each of metastatic carcinoma, amoebic liver abscess; liver storage disease and large cell dysplasia. The technique has gained popularity in our center because it is cheap, convenient, minimally invasive, quick and has high precision in obtaining samples. We therefore recommend this procedure in centers where liver diseases are common as a means of initial investigation.

Sera from 65 patients with primary liver carcinoma (PLC) and 69 sex- and age-matched controls were examined for Hepatitis B virus markers. Forty two of the patients (65%) and 25 controls (36%) were HBsAg positive. Anti-HBc was demonstrated in over 80% and in 84% of the study groups respectively. Over 70% of hepatitis B infection was anicteric and traditional surgical intervention correlated with prevalence of PLC. The data provide support for the etiological role of HBV in Nigerian patients with PLC; this is the first report that the incidence of PLC is highest in the northern Savannah region of Nigeria.
