Simple tandem repeat (TTTA)n polymorphism in CYP19 (aromatase) gene and breast cancer risk in Nigerian women.

BACKGROUND: Breast cancer is the most common cancer and the leading cause of cancer related deaths in women worldwide. The incidence of the disease is increasing globally and this increase is occurring at a faster rate in population groups that hirtherto enjoyed low incidence. This study was designed to evaluate the role of a simple tandem repeat polymorphism (STRP) in the aromatase (CYP19) gene in breast cancer susceptibility in Nigerian women, a population of indigenous sub-Saharan African ancestry. METHODS: A case-control study recruiting 250 women with breast cancer and 250 women without the disease from four University Teaching Hospitals in Southern Nigeria was carried out between September 2002 and April 2004. Participants were recruited from the surgical outpatient clinics and surgical wards of the Nigerian institutions. A polymerase chain reaction (PCR)-based assay was employed for genotyping and product sizes were detected with an ABI 3730 DNA Analyzer. RESULTS: Conditional logistic regression analysis revealed that harboring the putative high risk genotypes conferred a 29% increased risk of breast cancer when all women in the study were considered (Odds ratio [OR] = 1.29, 95% confidence interval [CI] 0.83-2.00), although this association was not statistically significant. Subgroup analysis based on menopausal status showed similar results among premenopausal women (OR = 1.35, 95% CI 0.76-2.41 and postmenopausal women (OR = 1.27, 95% CI 0.64-2.49). The data also demonstrated marked differences in the distribution of (TTTA)n repeats in Nigerian women compared with other populations. CONCLUSION: This study has shown that harboring 10 or more repeats of the microsatellite (TTTA)n repeats of the CYY19 gene is associated with a modest increased risk of breast cancer in Nigerian women.

Adult surgical emergencies in a developing country: the experience of Nnamdi Azikiwe University Teaching Hospital, Nnewi, Anambra State, Nigeria.

The goal of this study was to examine the adult surgical emergencies seen at the Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, with a view to proffering preventive solutions where appropriate and improving outcome. From the register of patients seen at the Casualty department and from the operations register in the main operation room of NAUTH, names and hospital numbers of adult patients treated as emergencies over a 5-year period, from 7 September 1998 to 6 September 2003, were obtained. The hospital folders were then retrieved from the Records Department. From each folder, the following details about each patient were extracted: age, sex, diagnosis at presentation, causative factors, treatment given, and outcome. A total of 902 adult patients were treated during the period. The commonest emergency operation was appendectomy for acute appendicitis in 139 patients (97 women and 42 men), followed closely by road traffic accidents (RTAs) involving 137 patients (103 men and 34 women). Gunshot injuries, which resulted mainly from armed robbery attacks, accounted for 127 cases. More men (113) sustained gunshot injuries than women (14). Of the 92 cases of acute intestinal obstruction seen, 62 occurred in women and 30 in men. Some 126 men presented with acute urinary retention, and two others presented with priapism. Governments at various levels should provide modern diagnostic tools for the accurate preoperative diagnosis of surgical emergencies in hospitals. Governments should also inculcate strict discipline into drivers using the highways, particularly in relation to abuse of alcohol and drugs. Good roads and adequate security should be provided for the people. The need for Pre-Hospital Care for the efficient evacuation of accident victims is emphasized. These measures will help to improve the management and outcome of surgical emergencies, and decrease the number of surgical emergencies resulting from RTAs and gunshot wounds.

Anthropometry and breast cancer risk in Nigerian women.

The recent upsurge in global obesity and the recognition of the role of metabolic syndrome and other correlates of obesity in the etiology of breast cancer and other chronic diseases has created the impetus for renewed interest in the role of anthropometric measures in breast cancer risk. This case-control study was designed to evaluate the role of anthropometric variables in breast cancer susceptibility in an indigenous sub-Saharan African population drawn from midwestern and southeastern Nigeria, a population grossly underreported in the global epidemiologic literature. Study participants were 250 women with breast cancer who were receiving treatment in the surgical outpatient clinics and surgical wards of four university teaching hospitals located in midwestern and southeastern Nigeria, while the controls were 250 age-matched women without breast cancer or other malignant diseases being treated for other surgical diseases in the same institutions between September 2002 and April 2004. Waist:hip ratio (WHR) was associated with a significant 2.5-fold increased risk of premenopausal breast cancer (odds ratio [OR] = 2.56, 95% confidence interval [CI] 1.48-4.41] and a 2-fold increased risk of postmenopausal breast cancer (OR = 2.00, 95% CI 1.04-2.53). Increasing height conferred a modestly nonsignificant increased risk of premenopausal breast cancer (OR = 1.59, 95% CI 0.98-2.58). The study showed that WHR is a significant predictor of breast cancer risk in Nigerian women and measures to sustain increased physical activity and ensure healthy dietary practices are recommended to reduce the burden of obesity in the population.
