RESUMO
INTRODUCTION: The urinary bladder undergoes morphological and functional changes in patients with symptomatic benign prostatic enlargement (BPE). These detrusor changes reflect chronically increased intravesical pressure as a result of outlet obstruction. This study aims to determine the relationship between the Pre- and Post-op detrusor wall thickness (DWT), international prostate symptom score (IPSS), and duration of lower urinary tract symptoms (LUTS) in patients who had open simple prostatectomy (OSP). METHOD: This was a prospective study of a cohort of patients who had OSP for symptomatic BPE. The IPSS and symptom duration for each patient were noted. Each patient also had an abdominal ultrasound scan with a measurement of their DWT. Retropubic OSP was done for each patient. The detrusor wall thickness was also measured 12 weeks after the prostatectomy. RESULTS: Fifty-two patients completed the study; the mean age was 66.37 ± 8.09 years. The median pre-operative IPSS was 28 (IQR = 13.75), and the median duration of symptoms was 24 months (IQR = 37 months). The mean pre-operative DWT was 4.41 ± 1.38mm, while the mean post-operative DWT was 2.16 ± 0.98mm. The preoperative IPSS (p = 0.833) and duration of symptoms (p = 0.375) did not significantly correlate with the pre-operative DWT. There was a significant reduction in the mean DWT (p < 0.001) and IPSS (p < 0.001) following prostatectomy. CONCLUSION: DWT appears not to be significantly influenced by the severity or duration of LUTS. However, it reduced significantly following OSP with corresponding improvement in urinary symptoms.
INTRODUCTION: La vessie subit des changements morphologiques et fonctionnels chez les patients présentant une hyperplasie bénigne de la prostate (HBP) symptomatique. Ces modifications du détrusor reflètent une pression intravésicale chroniquement augmentée en raison de l'obstruction de la sortie. Cette étude vise à déterminer la relation entre l'épaisseur de la paroi du détrusor (EPD) avant et après l'opération, le score international des symptômes prostatiques (IPSS) et la durée des symptômes des voies urinaires inférieures (LUTS) chez les patients ayant subi une prostatectomie simple ouverte (OSP). MÉTHODE: Il s'agissait d'une étude prospective d'une cohorte de patients ayant subi une OSP pour une HBP symptomatique. L'IPSS et la durée des symptômes pour chaque patient ont été notés. Chaque patient a également subi une échographie abdominale avec mesure de leur EPD. Une OSP rétropubienne a été réalisée pour chaque patient. L'épaisseur de la paroi du détrusor a également été mesurée 12 semaines après la prostatectomie. RÉSULTATS: Cinquante-deux patients ont terminé l'étude ; l'âge moyen était de 66,37 ± 8,09 ans. L'IPSS médian préopératoire était de 28 (IQR = 13,75), et la durée médiane des symptômes était de 24 mois (IQR = 37 mois). L'EPD moyenne préopératoire était de 4,41 ± 1,38 mm, tandis que l'EPD moyenne postopératoire était de 2,16 ± 0,98 mm. L'IPSS préopératoire (p = 0,833) et la durée des symptômes (p = 0,375) n'ont pas significativement corrélé avec l'EPD préopératoire. Il y a eu une réduction significative de l'EPD moyenne (p < 0,001) et de l'IPSS (p < 0,001) après la prostatectomie. CONCLUSION: L'EPD ne semble pas être significativement influencée par la gravité ou la durée des LUTS. Cependant, elle a considérablement diminué après l'OSP avec une amélioration correspondante des symptômes urinaires. MOTS-CLÉS: Hyperplasie bénigne de la prostate, Épaisseur de la paroi du détrusor, Score international des symptômes prostatiques, Prostatectomie simple ouverte.

BACKGROUND: Findings from studies on obesity and benign prostatic enlargement (BPE) have been inconsistent. With a previous study done in our facility showing no correlation between anthropometric indices of obesity and BPE, this study aimed at reevaluating the association between obesity and BPE using sonographic indices of abdominal/central obesity. MATERIALS AND METHODS: Ninety consenting subjects with clinically confirmed BPE had their height and weight [(to calculate body mass index (BMI)] as well as waist and hip circumference [to calculate waist-hip ratio (WHR)] done. The subcutaneous, preperitoneal, and visceral fat thicknesses (SFT, PFT, and VFT, respectively) of these subjects and their prostate volumes were measured on transabdominal Ultrasonography (USS). Transrectal USS was also done to measure the total prostate and transitional zone volumes. Data were analyzed using SPSS version 22. RESULTS: WHR and waist circumference correlated positively with SFT (r = 0.325, P = 0.002 and r = 0.370, P = 0.000, respectively) and PFT (r = 0.209, P = 0.048 and r = 0.313, P = 0.003, respectively). While BMI correlated positively (r = 0.23, P = 0.029) with transrectal transitional zone volume, all three sonographic indices of adiposity correlated negatively (SFT: r = -0.223, P = 0.035; PFT: r = -0.321, P = 0.002; VFT: r = -0.242, P = 0.021) with transrectal total prostate volume. In addition, PFT correlated negatively with transabdominal prostate volume (r = -0.222, P = 0.037) and transrectal transitional zone volume (r = -0.211, P = 0.046). CONCLUSION: The relationship of BMI with transrectal transitional zone volume was a direct one, while that of SFT, PFT, and VFT with transrectal total prostate volume as well as PFT with transabdominal prostate volume and transrectal transitional zone volume was an inverse one.

BACKGROUND: A broad spectrum of renal vascular variations has been reported by anatomists and radiologists. The prevalence of these variations is extremely divergent in different populations. Therefore, radiologists and surgeons in different climes must be knowledgeable about the type and prevalence of the variants in their area of practice to avoid diagnostic pitfalls and for optimization of surgical techniques. OBJECTIVE: The objective of this study is to describe the types and prevalence of renal vascular variations among patients undergoing contrast-enhanced computerized tomography (CECT) of the abdomen in a Nigerian population, as well as provide a concise review of literature on the embryological basis and clinical significance of the identified variations. MATERIALS AND METHODS: This study was a retrospective review of 200 CECT of the abdomen to identify variations of arterial (accessory, early branching, and precaval) and venous (multiple, retroaortic, and circumaortic) anatomy of the kidneys. RESULTS: We studied 200 patients, 102 (51%) females and 98 (49%) males. Age range is 18-90 years (mean = 53.08 ± 17.01). Prevalence of any renal vascular variations was 50%, arterial variations were 37%, and venous variations were 13%. Variations were significantly more common in males, P = 0.000075. The most common arterial variant was the accessory renal artery (23%) seen in 10% (right) and 13.0% (left); early branching was seen in 4.0% (right) and 0.5% (left) as well as precaval right renal artery seen in 4.5%. Venous variants were late confluence 3.0% (right) and 2.5% (left); multiple veins was seen in 2.5% (right) and 2.5% (left) as well as retroaortic left renal vein seen in 2.0%. The inferior polar accessory artery was the most prevalent accessory artery. Early arterial bifurcation was significantly more common on the right (P = 0.016) while other vascular variants showed no statistically significant association with laterality. CONCLUSION: Variation of renal vascular anatomy is a frequent finding among Nigerians. Radiologists and surgeons must be aware of these variants for optimization of surgical techniques.

Bone infarction involving the orbit in sickle cell disease is not common. Bilateral orbital infarction in a previously undiagnosed sickle cell hemoglobinopathy has not been previously reported. In this report, we present a case of an 11-year-old previously undiagnosed sickle cell disease Nigerian girl with severe acute bilateral orbital infarction and retinal detachment to highlight that hemoglobinopathy induced orbital infarction should be considered in African children with acute onset proptosis with or without previous history of sickle cell hemoglobinopathy.
RESUMO
OBJECTIVES: To determine the prevalent age of symptomatic benign prostate hyperplasia (BPH), the average BPH volume, and the association between BPH volumes and the age, and anthropometrics in our immediate black community. PATIENTS, MATERIALS AND METHOD: Selected patients with lower urinary tract symptoms (LUTS) due to BPH with tissue diagnosis, and adult men of similar age group with no irritative or obstructive LUTS were prospectively studied from July 2003 to June 2009. The age, height and weight were recorded, prostate volumes determined with ultrasound, body mass index (bmi) calculated, and correlations determined between the prostate volume and the age, and anthropometrics. RESULTS: 105 patients aged 43-88 yrs (mean=64.4, 8.88 SD) managed for BPH were studied with 93 asymptomatic men aged 43-80 yrs (mean=56.15, 9.89 SD). The mean (SD) prostate volume, height, weight and bmi were 83.8 (37.7) ml, 1.67 (0.07) m, 63.6 (9.32) kg and 22.8 (3.03) kg/m2, and 24.5 (9.2) ml, 1.69 (0.06) m, 68.9 (10.6) kg and 24.2 (3.44) kg/m2 respectively for symptomatic and asymptomatic groups. In the symptomatic group, BPH volume showed significant positive correlation with the age (p=0.030), but no correlation with the weight (p=0.550), height (p=0.375) and bmi (p=0.840). In the asymptomatic group, prostate volume also showed significant positive correlation with the age (p=0.041), but no correlation with the weight (p=0.434), height (p=0.394), and bmi (p=0.203). CONCLUSION: The prevalent age of symptomatic BPH in our community is 43- 88 years with 83.79 (37.66) ml mean (SD) volume in symptomatic patients and 24.45 (9.21) ml in asymptomatic men. BPH volume correlates with age but not with anthropometrics. Lack of correlation with BPH volume suggests that anthropometrics may not be risk factors for development of BPH in our community.

The mechanisms involved in the pathogenesis of osteonecrosis of the femoral head in sickle cell disease are not fully known. The aim of this study was to identify risk factors for osteonecrosis of the femoral head among sickle cell disease patients. Clinical (frequency of painful crises and hospitalisation) and laboratory parameters (euglobulin clot lysis time, haematocrit, platelet count, and leucocyte count) of 25 consecutive patients with avascular necrosis of the femoral head from sickle cell disease were compared with those of 26 age- and sex-matched sickle cell disease patients without avascular necrosis. The group with avascular necrosis of the femoral head (mean age 23.7+/-4.9 years) had a significantly higher rate of painful crises (p = 0.03) and hospitalisations per year (p = 0.002) than the group without avascular necrosis (mean age 21.6+/-5.2 years). The group with avascular necrosis also had a significantly higher euglobulin clot lysis time than the group without avascular necrosis (p = 0.001). In conclusion, it appears that not all patients with sickle cell disease have impaired fibrinolytic activity. The aetiology of avascular necrosis in sickle cell disease is multifactorial.

INTRODUCTION: Devic's neuromyelitis optica is an inflammatory demyelinating disease that targets the optic nerves and spinal cord. It has a worldwide distribution and distinctive features that distinguish it from multiple sclerosis. There has been no previous report of neuromyelitis optica from our practice environment, and we are not aware of any case associated with antiphospholipid syndrome in an African person. CASE PRESENTATION: We report the case of a 28-year-old Nigerian woman who presented with neck pain, paroxysmal tonic spasms, a positive Lhermitte's sign and spastic quadriplegia. She later developed bilateral optic neuritis and had clinical and biochemical features of antiphospholipid syndrome. Her initial magnetic resonance imaging showed a central linear hyperintense focus in the intramedullary portion of C2 to C4. Repeat magnetic resonance imaging after treatment revealed resolution of the signal intensity noticed earlier. CONCLUSION: Neuromyelitis optica should be considered in the differential diagnoses of acute myelopathy in Africans. We also highlight the unusual association with antiphospholipid syndrome. Physicians should screen such patients for autoimmune disorders.
RESUMO
BACKGROUND: Avascular necrosis (AVN) especially of the femoral head, has long been recognised as a manifestation of sickle cell disease (SCD). Despite this knowledge the actual prevalence of this complication among sickle cell patients in Nigeria is not known. OBJECTIVE: To determine the prevalence and patterns of presentation of avascular necrosis of the femoral head in sickle cell disease. PATIENTS AND METHODS: A retrospective study carried out at the Orthopaedic and Haematology clinics of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. Four hundred and sixteen patients with sickle cell disease seen over a 15-year period. RESULTS: Of the 416 patients with sickle cell disease 340 (81.7%) had haemoglobin SS genotype while 76(18.3%) had SC genotype. Sixty-six (15.9%) patients 35 males (53%) and 31 females (47%) had clinical and radiologic features of avascular necrosis (AVN) of the femoral head. Fifty-three of them (80.3%) had Hb SS while 13 had Hb SC. The peak age incidence in both Hb SS and Hb SC was 21-30 years. Forty patients (60.6%) presented with stage IV disease (Ficat and Arlet Staging) while 21.2% had stage III and 18.2% had stage II. No patient was diagnosed in stage 1 or 0. CONCLUSION: The prevalence of AVN of femoral head in Hb SC and HbSS is similar i.e. the difference is not statistically significant (P=0.48). Most of our patients present late with advanced diseases. Considering the paucity of facilities available for total hip replacement in Nigeria and the young age group affected we recommend regular screening of patients with sickle cell disorder for AVN and regular community educational programmes for early diagnosis.

BACKGROUND: Pancreatic pseudocyst is a major health problem in the developed countries and its incidence is noted to be getting higher among the Caucasians as a result of better diagnostic techniques. This retrospective study was done to review the cases of pancreatic pseudocyst seen between 1991 and 1999 at the Obafemi Awolowo University Teaching Hospitals, Ile-Ife, Nigeria. The 5 cases seen over this period of study were used to illustrate its rarity. METHOD: The case notes of the patients managed for pancreatic pseudocyst during the period under review were studied and analysed to evaluate the different modes of presentation, investigations done and the modes of treatment. RESULTS: The age range of the patients varied between 23 and 70 years with three of them being male while two were female. The most common presenting symptom and sign were abdominal pain and abdominal mass. Abdominal ultrasonography, chest X-ray, upper gastrointestinal endoscopy and laboratory blood tests were the investigative procedures carried out. The treatment modalities were either conservative or surgical (operative). One patient had spontaneous resolution of the pseudocyst, 2 had external drainage while the remaining 2 had cystogastrostomy. Two of the patients responded well to treatment and were being followed up in the Surgical Out Patient Clinic, one died within 24 hours of surgery while the other developed diabetes mellitus 3 months post surgery and was referred to the physicians for follow-up. CONCLUSION: Though pancreatic pseudocyst remains uncommon in Nigeria, ultrasonography can play an essential role in assisting diagnosis while successful management of this condition is still possible in the absence of current endoscopic techniques of drainage.
