Prevalence of Linea nigra in patients with benign prostatic hyperplasia and prostate carcinoma.

BACKGROUND: Linea nigra (LN) is linear hyperpigmentation occurring from the umbilicus to the pubic symphysis. Although commonly associated with pregnancy (when it is known as linea gravidarum), it has been found in normal male and female individuals, particularly in the younger age group where estrogen or lack of sensitivity of androgen receptors has been suggested as a possible factor. From a previous study the incidence of LN varied in different genders, age groups, and certain clinical status such as pregnancy and, in men, benign prostate hyperplasia (BPH)/prostate carcinoma (PC). OBJECTIVE: The need to get a clinical feature that can aid diagnosis of PC, the commonest male neoplasm in Nigeria, at an affordable cost prompted us to look at the incidence of LN in three male populations (i.e., one with BPH, one with PC, and a control population unaffected by these two conditions). Gynecomastia and female hair distribution, two features considered hormone related were looked for additionally in the study population. The study was carried out in a teaching hospital in Ibadan, southwestern Nigeria. RESULTS: LN was found in 48% of PC, 26% of BPH, and 8% of controls. Female pubic hair was found in 48% of PC, 26% of BPH, and 12% of controls. Gynecomastia was found in 36% of PC, 12% of BPH, and 0% of controls. Differences between patients with BPH, PC, and controls regarding incidence of LN and female pubic hair were deemed explicable by chance (P = 0.17, Fisher exact test). Differences between PC and BPH patients with respect to gynecomastia were deemed inexplicable by chance (P = 0.008, Fisher exact test). CONCLUSION: LN alone cannot be used to differentiate PC and BPH. Further studies will be needed to characterize the role of LN in these conditions in men before and after treatment.

Daycase urology at Ibadan, Nigeria: a ten year review.

INTRODUCTION: The objective of the study was to report the extent of urological surgeries performed as day cases in a major tertiary hospital in Ibadan and document the outcome. METHODS: We retrospectively reviewed the data of all urologic patients treated at the day-case theatre between January 2000 and December 2009. The parameters evaluated were: age, diagnosis, type of surgery/procedure, anaesthesia administered and the rank of the surgeon. Day case endoscopic procedures as well as prostate biopsies were excluded from the study. RESULTS: In total, 1292 patients were managed, 290 (22.4%) were children aged between 5 days and 15 years while 1002 (77.6%) adults aged between 17 years and 91 years. The majority of the procedures were carried out by the senior registrars (1169 cases, 90.5%) and consultants were involved in 123 cases (9.5%). General anaesthesia was primarily used in children (158 children vs. 4 adults), while local anaesthesia was used only in adults. 131 (45.2%) children had no anaesthesia for circumcision. The most common procedures performed in adults were varicocelectomy (426 cases, 42.5%), orchidectomy (332 cases, 33.1%), testicular biopsy (120 cases, 12.0%). While in children male circumcision (231 cases, 79.7%) was the main procedure performed. CONCLUSION: The day-case theatre is still suitable for day case urologic procedure in our setting. The common procedures are varicocelectomy, orchidectomy, and open testicular biopsy in the adults. While in children, male circumcision is commonly carried out.

Epidermal inclusion cyst as a rare complication of neonatal male circumcision: a case report.

INTRODUCTION: Ibadan, Nigeria, has a very high rate of complications of male circumcision. In a previous survey, redundant or excessive loss of foreskin, skin bridges and injury to the glans penis were the major types of complications identified. Epidermal inclusion cyst complicating neonatal male circumcision appears to be extremely rare, and an extensive search of all databases revealed no reports in the recent literature. CASE PRESENTATION: In 1992, a 10-year-old boy was seen at the urology outpatients clinic presenting with a globular swelling in the penile skin located at the ventral surface proximal to the coronal sulcus. The histology of the excised mass revealed an epidermal inclusion cyst. Since then, he has remained healthy. CONCLUSIONS: Epidermal inclusion cyst complicating male neonatal circumcision is extremely rare. The diagnosis is easy and a simple total excision is curative.

Thread embedded into penile tissue over time as an unusual hair thread tourniquet injury to the penis: a case report.

INTRODUCTION: Hair thread tourniquet syndrome has been recognized since the 1960s. Since then, sporadic reports have appeared in the literature describing different degrees of strangulation and/or amputation of the penis caused by a hair thread being inadvertently tied around the penis. CASE PRESENTATION: A 9-year-old boy presented with a 3-year history of hair thread tourniquet injury to his penis. Instead of the usual strangulation or amputation, the tourniquet had become embedded into the penile tissue, manifesting with exuberant granulation tissue and a tight urethral stricture. At surgery, the intact tourniquet was still in place, embedded in dense fibrous tissue and associated with a dense urethral fibrosis which measured about 2 cm long. The tourniquet was divided and removed, the fibrotic urethra excised and a distal penile pedicled skin flap used to perform a single-stage substitution urethroplasty. The patient has been voiding well for 28 months. CONCLUSION: This case is unusual and is the first report of its kind. It is also the first report of a hair thread tourniquet as the cause of pediatric penile injury in Nigeria.
