Unusual presentation of advanced prostate cancer in a black population of South-Western Nigeria

There are growing concerns on the varying pattern of advanced prostate cancer (PCa) presentation across the world. We report some of the unusual presentations of PCa at the Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, South-Western Nigeria. A review of all patients with histologically confirmed PCa who had unusual presentations between January 2014 and December 2015 was done. Unusual presentation was defined as an atypical feature in the absence of lower urinary tract symptoms (LUTS), with the diagnosis of PCa only suspected after abnormal digital rectal examination (DRE) and/or elevated prostate specific antigen (PSA) assay. Thirteen patients had an unusual presentation in OAUTHC during the study period. Five (38.5%) had left supraclavicular swellings while four (30.8%) had haematochyzia and tenesmus. Other unusual presentations include large bowel obstruction requiring emergency colostomy (2;15.4%) and a scalp mass (1;7.7%). All patients had appropriate treatment for stage of CaP and are being followed up in the out-patient clinic. The change in presentations of PCa may suggest the need for DRE and serum PSA assay among all middle-aged and elderly men presenting at health facilities. Large scale studies on PCa across different population groups may also help at identifying related clinical, demographic and epidemiological factors as well as possible validation of some of these unusual presentations

Experience with arteriovenous fistula creation for maintenance hemodialysis in a tertiary hospital in South-Western Nigeria

End-stage renal disease (ESRD) is prevalent in our region. A major mode of treatment is by maintenance hemodialysis, and reliable vascular access is paramount for this to be successful. Arteriovenous fistula (AVF) creation offers permanent vascular access in patients with ESRD. We present our experience on AVF creation over a 10-year period. Our objective was to retrospectively review the outcome of all cases of AVF that have been created for ESRD patients at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife Nigeria between January 2006 and December 2015. The demographic characteristics, indications, clinical and intraoperative findings, operative complications and outcomes were filled into a pre-designed proforma. A total of 80 cases were reviewed. The age range was 17-80 years, with a mean of 49.03 ± 16.34 years. Males (85%) were more common than females (15%). Chronic glomerulonephritis and hypertension accounted for about 77.5% of etiology of ESRD in these patients. The left (non-dominant) upper limb was used in 88.1% of cases whereas 11.9% were created on the right upper limb. The distal radio-cephalic AVF (76.3%) was most commonly performed; with either the end (vein) to side (artery) (68.8%) or side-to-side (31.2%) anastomotic techniques employed. There was a primary failure in six patients (7.5%). Primary failure was more common in diabetics and thrombosis (7.5%) was the most common cause for primary failure. AVF creation has very good outcome in well-selected patients
