It is a significant contributor to the burden of diseases and affects over a million men. This study investigated the levels of malondialdehyde and plasma total antioxidant capacity among patients with prostate cancer in Sokoto. This case-control study was conducted among 28 confirmed prostate cancer patients attending the Urology clinics in Usmanu Danfodiyo University Teaching Hospital and Sokoto Specialist Hospital in North Western Nigeria. Twenty-eight age-matched healthy males were monitored as controls. Determination of Total Antioxidant Capacity (TAC) was determined using Ferric Reducing Antioxidant Power (FRAP) reagent while the Malondialdehyde in serum was determined as a conjugate with Thiobarbituric acid (TBA) acid. Data were collected using a semi-structured interviewer-administered questionnaire. Data were processed using SPSS version 20 and results were reported as Mean ± Standard deviation. The malondialdehyde level was significantly increased (p < 0.0001) among subjects with prostate cancer (0.215 ± 0.06) compared to controls (0.073 ± 0.04). The plasma total antioxidant capacity decreased significantly among the subjects (247.9 ± 63.3) compared to controls (743.3 ± 104.40) (p < 0.0001). The findings from this indicated a high Malondialdehyde (lipid peroxidation indicator) and low levels of Total Antioxidant Capacity among prostate cancer patients as evidence of redox imbalance. Subjects in monogamous relationships compared to polygamous, rural dwellers, farmers, individuals of Hausa ethnicity and subjects who reported no family history of the disease were more predisposed to prostate cancer. Further epidemiological studies are needed to determine the predisposing factors and the potential role of these markers in the diagnosis, prognosis and management of prostate cancer patients in Sokoto in particular and Nigeria in general. We recommend that Malondialdehyde and Total Antioxidant Capacity be routinely monitored among patients with prostate cancer patients in the area.展开更多

This paper attempts to present clinical and histologic patterns, and therapeutic challenges of oropharyngeal tumors from three selected health facilities in North Western Nigeria. Materials and Methods: The medical records of patients seen in the Usmanu Danfodiyo University Teaching Hospital, Sokoto, Federal Medi- cal Centre Birnin Kebbi and Shepherd Specialist Hospital, Sokoto with oropharyngeal tumors over a fourteen-year period were reviewed (January 2000 to December 2013). Results: A total of 36 patients were seen. Twenty (56%) were males and 16 (44%) were females, making the male:female ratio, 1.3:1, (P value of 0.004 for the null hypothesis). The age range was 3 to 80 years, with a mean age of 45.5 years. Majority of patients were in their 5th decade of life (33%). Nineteen (53%) patients presented with dysphagia, 11 (28%) with mass in the mouth (soft palate), 7 (17%) with neck swelling, while 3 patients (7%) presented with upper airway obstruction. Twenty-six patients (72%) presented at an advanced stage. Squamous cell carcinoma accounted for 31% of the cases, followed by lymphoma 14%, adenoid cystic carcinoma 8%, pleomorphic adenoma 5%, mucoepidermoid carcinoma 5%, peripheral nerve sheath tumour 3%, alveolar rhabdomyosarcoma (3%), tuberculoma (3%) and inflammatory polyp (3%). Surgery was carried out in 31 cases (86.1%) for the purpose of obtaining biopsy and removal of tumour, followed by chemotherapy (5.5%) and radiotherapy (5.5%) where histologic diagnosis was malignant. Five (13.9%) did not consent for any intervention. Conclusion: Oropharyngeal tumours are varied in presentation. Squamous cell carcinoma (31%) was the commonest histologic type followed by lymphoma (14%) and adencystic carcinoma (8%). About 72% of the cases were in advanced stages (T4). More than half of the tumours (53%) were of soft palate origin.展开更多
