Thermaland non-thermal pasteurization of citrus fruits: A bibliometrics analysis.

Thermal and non-thermal pasteurization (TNP) process of food is not new to food technology, disparities in the merits and demerits of the two pasteurizations necessitate their uses concurrently. Bibliometric analysis of the subject matter is expedient to analyses of database for published publications. Especially to provide times, state-of-the art innovations and prospects of the techniques. In addressing these lacunas, we utilized VOSview visualization to establish connections among crucial elements within a dataset of 495 research publications gathered from Web of Science. This approach facilitated the identification of links and collaboration networks among key factors in the research landscape. Analysis of publications indicate thermal pasteurization is an age long practices, while non-thermal pasteurization is gaining more acceptance. This study exposed ranking differences in scholar's collaboration, citations of scholars, impactful institution and most published countries. United State, China, United Kingdom have largest publications of research in TNP among the top 10 countries. Coupling network and Sankey illustration showed new area of research where new researchers and scholars can begin new phase of findings.

Effect of Perioperative Tranexamic Acid on Blood Loss following Open Simple Prostatectomy: A Prospective Review in Nigerian Men.

BACKGROUND: Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement. METHODOLOGY: This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented. RESULTS: Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups. CONCLUSION: The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.

CONTEXTE: L'hémorragie est une complication courante après une prostatectomie simple ouverte et les patients doivent parfois recevoir une transfusion sanguine. Il a été démontré que l'acide tranexamique réduit la perte de sang après une résection transurétrale de la prostate et une prostatectomie radicale ouverte. Cette étude a évalué l'effet de l'administration intraveineuse périopératoire d'acide tranexamique sur les pertes sanguines et les taux de transfusion sanguine chez des patients ayant subi une PSO pour hypertrophie bénigne de la prostate. MÉTHODOLOGIE: Il s'agissait d'une étude comparative de patients dont la prostate de 60 g et plus était documentée et qui devaient subir une PSO. L'hématocrite de base a été effectué un jour avant la chirurgie. Les patients ont été répartis aléatoirement dans le groupe acide tranexamique, qui a reçu de l'acide tranexamique periopératoire par voie intraveineuse, et dans le groupe sans TXA, qui a reçu un placebo. Tous les patients ont subi une prostatectomie rétropubienne simple ouverte. L'hématocrite postopératoire a été évalué, et la perte de sang calculée à l'aide de la formule de Gross modifiée. Le taux de transfusion a été documenté. RÉSULTATS: Cinquante-six patients ont participé à cette étude et ont été randomisés entre le groupe avec acide tranexamique et le groupe sans acide tranexamique. L'âge moyen des patients du groupe acide tranexamique était de 66,07 ±7,08 ans et était comparable à celui du groupe sans acide tranexamique qui était de 66,50 ± 8,80 ans (P =0,842). La perte sanguine totale médiane était plus faible dans le groupe avec acide tranexamique (502 ml, IQR 613) que dans le groupe sans acide tranexamique (801 ml, IQR 1069). La différence de la perte de sang médiane entre les deux groupes était de 299 ml (U 275, P 0,055). Le taux de transfusion sanguine était inférieur dans le groupe acide tranexamique (6 patients, 21%) par rapport au groupe sans acide tranexamique (11 patients, 39%), (P =0,146). Il n'y avait pas de différence dans les taux de complication entre les deux groupes. CONCLUSION: L'utilisation de l'acide tranexamique chez les patients subissant une prostatectomie simple ouverte a montré une tendance à la réduction de la perte de sang peropératoire et un besoin moindre de transfusion sanguine.

Simple Prostatectomy for Giant Benign Prostatic Hyperplasia in Sub-Saharan Africa: Case Series and Literature Review.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a common cause of bladder outlet obstruction in men worldwide. African men are known to have larger mean prostate volumes than other races. Giant benign prostatic hyperplasia (GBPH) is defined as prostate size greater than 200 grams. Management of GBPH is associated with several challenges which have been under-reported from the African sub-region. OBJECTIVE: To highlight the peculiarities of clinical presentation, surgical management and outcome of GBPH. PATIENTS AND METHODS: Men with BPH and trans-rectal ultrasound estimated prostate volume > 200 grams who were scheduled for open simple prostatectomy between January and December 2016 in our hospital were prospectively studied. RESULTS: Four patients with GBPH had simple prostatectomy during the period under review. Their ages ranged from 68 to 78 years with a mean age of 73.7 years.Three patients (75.0%) had transvesical prostatectomy while one (25.0%) had retropubic prostatectomy. The enucleated prostate specimen were found to weigh 312.1g, 396.4g, 420.8g and 450.0g respectively with mean weight of 394.8 ±50.2g and mean operation time of 111.7 ±19.7 minutes. They all had blood transfusion post-operatively with mean transfusion of 3±1.5 pints of blood per patient with relatively longer hospital stay (mean 10 days). CONCLUSION: The surgical management of GBPH can be quite challenging. Recalcitrant gross haematuria, chronic urinary retention and renal impairment are possible modes of presentation. Open simple prostatectomy is the best option for treatment in our environment. It is associated with improved quality of life and minimal morbidity in expert hands.

INTRODUCTION: L'hyperplasie bénigne de la prostate (HBP) est une cause fréquente d'obstruction de la vessie chez les hommes du monde entier. Les hommes africains sont connus pour avoir des volumes de prostate moyens plus importants que les autres races. L'hyperplasie bénigne géante de la prostate (GBPH) est définie comme une taille de la prostate supérieure à 200 grammes. La gestion du GBPH est associée à plusieurs défis qui ont été sous-déclarés dans la sous-région africaine. OBJECTIF: Mettre en évidence les particularités de la présentation clinique, de la prise en charge chirurgicale et du résultat de la GBPH. PATIENTS ET MÉTHODES: Les hommes atteints d'HBP et d'une échographie trans-rectale d'un volume prostatique estimé> 200 grammes qui devaient subir une prostatectomie simple ouverte entre janvier et décembre 2016 dans notre hôpital ont été étudiés de manière prospective. RÉSULTATS: Quatre patients atteints de GBPH ont eu une prostatectomie simple au cours de la période sous revue. Leur âge variait de 68 à 78 ans avec un âge moyen de 73,7 ans). Trois patients (75,0%) ont eu une prostatectomie transvésicale et un (25,0%) une prostatectomie rétropubienne. L'échantillon de prostate énucléé pesait respectivement 312,1 g, 396,4 g, 420,8 g et 450,0 g avec un poids moyen de 394,8 ± 50,2 g et une durée opératoire moyenne de 111,7 ±19,7 minutes. Ils ont tous eu une transfusion sanguine postopératoire avec une transfusion moyenne de 3 ± 1,5 pintes de sang par patient avec un séjour à l'hôpital relativement plus long (10 jours en moyenne). CONCLUSION: La prise en charge chirurgicale de la GBPH peut être assez difficile. Une hématurie macroscopique récalcitrante, une rétention urinaire chronique et une insuffisance rénale sont des modes de présentation possibles. La prostatectomie simple ouverte est la meilleure option de traitement dans notre environnement. Elle est associée à une meilleure qualité de vie et à une morbidité minimale entre des mains expertes. MOTS CLÉS: Hyperplasie bénigne géante de la prostate, prostatectomie simple, Afrique subsaharienne.

HISTOMORPHOLOGICAL PATTERN OF UROLOGIC MALIGNANCIES IN ILE-IFE, SOUTH-WESTERN NIGERIA.

INTRODUCTION: The last decade witnessed a remarkable rise in the prevalence of several malignant diseases in Nigeria. Whether Urologic malignancies (UM) have followed the same trend remains to be studied. The pattern of UM diagnosed in a Nigerian tertiary hospital is hereby presented. Our aim was to determine the pattern and prevalence of histologically diagnosed UM in Obafemi Awolowo University Teaching Hospitals Complex. Ile-Ife, Nigeria. MATERIALS AND METHODS: A 10-year retrospective review of all patients diagnosed with UM was carried out between January 2005 and December 2014. Data was obtained from the patients' case files and the Ife-Ijesha Cancer registry. Information obtained included demographic characteristics, site of origin and histology. Data was analysed with Statistical package for Social sciences (SPSS) Version 20. RESULTS: A total of 4675 malignancies were histologically confirmed during the study period. UM accounted for 420 (8.9%) of total malignancies. Prostate cancer was the commonest UM with 315 (75%) cases. Others include renal tumours 62(14.8%), bladder tumours 29 (6.9%), testicular tumours 13(3.1%) and scrotal tumour 1(0.2%). UM were commoner in males (348, 88.8%) than females (47, 11.2%) and accounted for 13.8% and 2.18% of all tumours in males and females respectively. CONCLUSION: This study revealed a rising prevalence of UM most especially Prostate and Renal Cancers among other malignancies in Ile-Ife.

Variations of renal vascular anatomy in a nigerian population: A computerized tomography studys.

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.

SCROTAL SQUAMOUS CELL CARCINOMA AND ASSOCIATED BLINDNESS: A CASE REPORT AND LITERATURE REVIEW.

BACKGROUND: Carcinoma of the scrotum is a rare disease which has been linked with occupational exposure to certain industrial carcinogens. Scanty reports of scrotal carcinoma exist in literature but in very few places worldwide. To our knowledge, there has been one documented report of scrotal carcinoma in our country and this is the first report of scrotal carcinoma in over 45years existence of our tertiary Health institution. We present the clinical evaluation, investigations and surgical intervention of a blind elderly welder with squamous cell carcinoma of the scrotum at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria. CASE PRESENTATION AND MANAGEMENT: A 65 year-old blind welder presented to us with a painless fungating scrotal mass of two years' duration. He had prior incision and drainage of the swelling in a primary health centre but this failed to heal, with copious purulent discharge. The mass measured 20cm x 15cm x 8cm and was inseparable from the right testis and cord structures, with infiltration of the root of the penis. The inguinal lymph nodes were not enlarged. CT scan confirmed localized scrotal tumour and biopsy confirmed squamous cell carcinoma.He subsequently had wide local excision of the scrotal tumour (with at least 2cm free margins), right total orchidectomy and advancement flap closure of scrotal defect. Histopathological reports corroborated the earlier findings and confirmed tumour free margins. He has remained well 18 months after surgery. CONCLUSION: Squamous cell carcinoma of the scrotum, though rare, is the commonest malignancy affecting the scrotum worldwide. Surgery still remains the mainstay of treatment and early intervention improves the chances of a favourable outcome.

Benign prostate hyperplasia: average volume in southwestern Nigerians and correlation with anthropometrics.

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.

Benign prostate hyperplasia: average volume in southwestern Nigerians and correlation with anthropometrics.

AIMS AND 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. PATIENTS, MATERIALS AND METHODS: 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, the age and anthropometrics. RESULTS: One hundred and five patients aged 43-88years (mean=64.4, 8.88SD) managed for BPH were studied with 93 asymptomatic men aged 43-80years (mean=56.15, 9.89SD). 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 43-88years 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.

Testicular schistosomiasis: a case report.

AIMS AND OBJECTIVES: To report a case of testicular Schistosomiasis with a suspicion of testicular cancer. PATIENT AND METHODS: Hospital record of a 16 year old patient with histopathology confirmation of testicular Schistosomiasis was reviewed and summarised. The patient who had painless testicular nodules and ultrasound features of heterogenous echotexture and hypoechoic focus was diagnosed as testicular cancer and treated with radical orchidectomy. Histopathology confirmed testicular Schistosomiasis and the patient had additional praziquantel therapy. RESULTS: Patient was followed up for over 26months post-operative. CONCLUSIONS: Testicular Schistosomiasis can mimick malignant testicular tumour. Hard nodular testicular mass in a patient with recent past history of schistosomiasis should arouse suspicion of testicular Schistosomiasis. Awareness and early presentation will prevent unwarranted orchidectomy.

Short hospital stay after appendicectomy.

AIMS AND OBJECTIVES: To determine the applicability of short hospital stay after appendicectomy in rural and semi-urban Nigerian community. PATIENTS AND METHODS: A 30-month prospective study on patients with uncomplicated acute appendicitis was carried out The age ranged from 5-70 years, mean of 28.7 years, there was almost even sex distribution between male and female. All the patients presented with clinical evidences of acute appendicitis. RESULTS: The operative findings were inflamed and oedematous appendix in about 80%, minimal exudates drained in only about 25% of the patients. Postoperative wound complications occurred in 1.3-5% of patients. All the postoperative complications were successfully managed in the outpatient clinic. 71.8% were discharged on the 2nd postoperative day, 20.5% on 3rd postoperative day, 4 (5%) on 4th postoperative day and 1(1.3%) each on 5th and 7th day. There was postoperative pain tolerance and late mobilisation in those who stayed for 3-4 days; moderately severe wound infection was responsible for those who stayed for 5th- 7th day. CONCLUSION: Short hospital stay after appendicectomy was possible in majority of patients with uncomplicated acute appendicitis. Minimal postoperative fluid therapy and antibiotic administration was adequate in well-selected cases.

Primary Swenson's pull-through in children with chronic constipation: a preliminary report.

BACKGROUND: The discrepancy in diameters of the resected ends coupled with the heavy faecal loads in the colon of chronically constipated children with Hirschsprung's disease makes definitive primary pull-through procedure quite difficulty in this group. PATIENTS AND METHODS: Four consecutive patients (aged 5 months to 11 years) who presented with chronic constipation were given warm saline enema along with Castor oil per oram twice daily for 1 week before and 2 weeks after full-thickness biopsies that confirmed Hirschsprung's disease. All patients had intravenous Cefuroxime or Ceftriaxone plus Metronidazole at induction of anaesthesia. Intra-operatively, the levels of resections were 6-8 cm proximal to the most contractile part of the colon adjacent to the transition zone observed after complete division of mesenteric vessels. RESULTS: There were three males and one female, aged 5 months to 11 years. The levels of aganglionosis were in the rectosigmoid region, except one in the descending colon. There was one case each of anastomotic stenoses, mild enterocolitis and deep peri-anal excoriation. The bowel motions were two to four times daily within 1 month post-operatively. CONCLUSION: It can be concluded from this preliminary study that with pre-operative saline enema and oral Castor oil for about 3 weeks in chronically constipated children with Hirschsprung's disease primary pull-through procedures can be performed successfully. However, further prospective work is required with this method.

Quality of documentation of urethral catheterization in a Nigerian teaching hospital.

BACKGROUND: Urethral catheterization is a common minimally invasive procedure with well-known complications some of which may be severe. Quite often, a clinician is invited to manage the short and long-term complications of the procedure without adequate records of the procedure itself. OBJECTIVES: This study aims to determine the quality of documentation of urethral catheterization in our health institution. METHODS: This prospective study was carried out over a period of 1 month. The documentations in the medical notes and nursing records with respect to urethral catheterisation were assessed using 10 different parameters with the aid of a pro-forma. Statistical analysis was done with the Wilcoxon signed ranks test. RESULTS: A total of 89 patients were catheterised in the wards, the emergency departments and the theatre. All the catheterizations were performed by doctors. The overall quality of documentation of catheterisation was poor: It was significantly worse in the medical notes than the nursing records with 28% of all cases documented by the nurses not documented by the physicians. Documentation in the theatre and emergency were worse, while there was no documentation of aseptic technique in any patient. An 11% incidence of complications was noted. CONCLUSION: The quality of record keeping concerning urethral catheterization was inadequate. This is important not only for patients' care, but also for medico-legal purposes. We therefore recommend regular audit and introduction of protocols for proper documentation.

Laryngeal carcinoma: our experience at Obafemi Awolowo University Teaching Hospital complex, Ile-Ife, Nigeria.

OBJECTIVES: To determine the prevalent age, frequency, pattern ofpresentation, investigations and outcome of management of laryngeal carcinoma in our environment. DESIGN: 10 year retrospective study (January 1994 to December 2003). SETTING: Teaching hospital. SUBJECTS: 13 patients with tissue diagnosis managed for laryngeal carcinoma. MAIN OUTCOME MEASURES: The age, sex, occupation, presentation, use of cigarettes and alcohol, investigations, tissue diagnosis, outcome of management and duration of follow up were extracted from hospital records and analysed. RESULTS: The age of patients ranged 38 to 88 years (median 69, male: female ratio=12:1). The histopathology was squamous cell carcinoma in all. Common symptoms included hoarseness of voice and breathlessness in all the patients, cough and weight loss in seven patients and otalgia in six. Only one patient indulged in alcohol while two were regular cigarette smokers. All the patients presented in stage IV with respiratory distress necessitating emergency tracheostomy in all. Seven patients had total laryngectomy plus post-operative radiotherapy while two patients had pharyngo-laryngectomy, thyroidectomy and radical neck dissection plus post-operative radiotherapy and thyroxine supplement. Post operative complications included pharyngocutaneous fistula in two patients, pharyngeal stenosis, stoma stenosis, and hypocalcaemia with hypothyroidism in one patient each. The fistulae were management conservatively. Prognosis was good despite late presentation. CONCLUSION: Laryngeal carcinoma occurs predominantly in males. Presentation is late with hoarseness of voice and breathlessness in our community. Soft tissue neck X-ray is a useful diagnostic tool. Scarcity of radiotherapy centres, ignorance, local taboos, poverty and poor recognition by general medical practitioners negatively affected management of the patients. Laryngeal carcinoma should be excluded when managing elderly patients for bronchial asthma.

Adult nephrectomy: our experience at Ile-Ife.

OBJECTIVES: To determine indications for adult nephrectomy in our community and the outcome of the procedure in our Institution. MATERIALS AND METHOD: Records of adult patients scheduled for nephrectomy at Obafemi Awolowo University Teaching Hospital from January 1993 to December 2004 were reviewed. Information extracted and analysed included age of patient, sex, presentation, investigations, indication, type and outcome of nephrectomy, histopathology result and duration of follow up. RESULTS: During the period, thirty adult patients mean age 42.73 yrs (range 16-80 yrs, M:F = 2:1) were scheduled for nephrectomy. Indications included suspicion of malignancy in 19 (63.3%) patients, protracted loin pain in non-functioning kidney in 2 (6.7%), uncontrollable bleeding in a patient with bilateral polycystic kidney (3.3%), pyonephrosis with septicaemia in a patient (3.3%), kidney injury (grade 5) in 2(6.7%) and kidney donation for transplantation in 3(10%). Ultrasound and intravenous urography were useful in the patients' evaluation. Twenty-seven (90%) patients were operated upon, but only 25 (83.3%) had nephrectomy. Sixteen (53.3%) had radical nephrectomy, 5 (16.7%) had simple nephrectomy, 3 (10%) had nephro-ureterectomy, and one (3.3%) had partial nephrectomy. Major surgical complications included wound sepsis (18.5%) and primary haemorrhage (7.4%). The overall morbidity and mortality rates were 7.4% and 3.7% respectively. Postuninephrectomy, patients' renal function remained stable after an average of 34.05 months follow-up. CONCLUSION: Renal tumours constitute the main indication for adult nephrectomy in our community. Kidney injury, kidney donation, and pyonephrosis are relatively uncommon indications. Open nephrectomy, which remains our local practice, is safe and unilateral nephrectomy is compatible with normal life.

Complete recovery of renal allograft function after sixty days of delay following living related transplantation.

Delayed graft function (DGF), a term employed when a newly transplanted organ does not function efficiently is commonly observed following cadaveric renal transplantation but is very rare after living related transplants. We present a 31-year-old female recipient of a related donor kidney (mother) who had DGF following trans-plantation due to acute tubular necrosis, probably caused by partial allograft arterial thrombosis, which recovered function after 60 days. Appropriate use of allograft biopsy should be encouraged even in resource-limited settings lest the allograft be assumed to have failed irreversibly.

Malignant renal tumors in adults: a ten-year review in a Nigerian hospital.

This study was undertaken to determine the age, sex, pattern of presentation, histopathology and outcome of management of adult patients with malignant renal tumors (MRT) in Nigeria. Using hospital records, a retrospective study was performed covering the period between January 1997 and December 2006. A total of 18 adult patients had been diagnosed to have MRT during this period. Information extracted and analyzed included the age of the patient, sex, presentation, investigations, type of histopathology, management and duration of follow-up. The mean age of the study patients was 47.5 years (range 16-80 yrs). The male: female ratio was 13 : 5 and the mean duration of symptoms was 43.6 weeks (range 2-104 wks). Sixteen patients (88.9%) presented in advanced stage. Symptoms included loin pain in 17 (94.4%), abdominal swelling in 15 (83.3%), weight-loss in 13 (72.2%) and hematuria in nine (50.0%). Ultrasound and intravenous urography assisted greatly in making the diagnosis. Thirteen patients (72.2%) underwent radical nephrectomy, tumors were not resectable in two (11.1%) and three others (16.7%) were deemed unfit to undergo surgery. The average tumor mass removed at surgery was 1.884 Kg (range 0.48-3.82 Kg). Renal cell carcinoma (RCC) accounted for 13 of the tumors (72.2%). Surgical complications include primary-hemorrhage, septicemia and tumor recurrence in one patient each (7.6%). Morbidity and mortality rates were 7.6% each. The average post-operative hospital stay and follow-up duration were 9.3 days and 37.5 months respectively. Our study suggests that RCC is the major MRT in our community. Most cases still present late with loin pain and swelling, weight loss and hematuria. This late presentation and sarcomatous type of tumor have negative influence on prognosis. Radical nephrectomy is beneficial in operable, locally advanced, non-metastatic MRT.

Testicular Torsion : a Fifteen Year Review in a Nigerian Teaching Hospital

Aim and Objectives: To determine the prevalent age; presentation; duration of symptoms before intervention; and outcome of management of testicular torsion (TT) in our community. Design: A fifteen-year retrospective study. Setting: University Teaching Hospital. Materials and Method: Records of patients managed for TT; January 1992- Decem- ber 2006; were reviewed. Records of 91 out of 106 patients managed during the period were available for review. The age of patient; presentation; duration of symptoms; predisposing factors; interval between presentation and operation; and outcome of management were extracted and analyzed. Results: Ninety-one patients; mean age 20.1yrs (range 8-34) were reviewed. The average duration of symptoms at presentation was 26.7hrs (range 1.5- 168). The patients were mostly 74(81.3) students. All of them presented with scrotal pain; and 66(72.5) had scrotal swelling (Left: Right=1.8:1). Torsion was partial (180-270o) in 14(15.4); and complete (360o-1440o) in 77(84.6). Intra-scrotal anatomic abnormalities were observed in 77(84.6) patients. Testes were viable in 59(64.8) patients offered bilateral orchidopexy and gangrenous in 32(35.2) that had orchi- dectomy with contralateral orchidopexy. The average duration of hospital stay was 2.8days. Most of the patients 76(83.5) were lost to follow up within 3 weeks postoperative. Conclusion: TT occurs in patients aged 8-34yrs in our immediate community. Presentation is late and most patients 77(84.6) have predisposing congenital abnormalities. There is a need for increase awareness by the general public and the health personnel's of the danger posed by delay in treating TT. Where doubts exist; early scrotal exploration should be the investigation and intervention of choice to prevent irreversible damage to the germ cells

Internal jugular and subclavian catheterisation: indications, problems and prospects in a Nigerian dialysis centre.

AIMS AND OBJECTIVES: To highlight the indications, problems and prospects of bedside non-surgically inserted jugular and subclavian dual lumen catheters. PATIENTS AND METHODS: Renal failure patients being managed in our centre with indications for central catheterisation were consecutively recruited at presentation. They had bedside non-surgical jugular and subclavian insertion of central catheters using modified Seldinger wire technique and the performance of the catheters monitored. RESULTS: Sixteen patients aged between 23 and 65 years had 32 central catheterizations during the 12-month period. The indications included its use as haemodialysis access in all catheterisations, additional indications were CVP monitoring in 5, and parenteral hyperalimentation in 1. Three catheterisations were in right subclavian vein, 4 in left internal jugular vein and 25 in right internal jugular vein. The duration of use ranged between 3 days and 11 weeks and blood flow rate used ranged between 250 and 350 mls/min. Nine (28.1%) catheterisations were complicated with exit site and systemic infection. Catheter blockage and accidental catheter removal were recorded in 3 patients each. Carotid artery puncture was recorded in 2 patients but haemostasis was maintained with direct digital compression. CONCLUSION: We conclude that percutaneous bedside internal jugular and subclavian (venous) catheterisation using dual lumen catheter is safe and devoid of major complications.

Pattern of antibiotic therapy and clinical outcome in acute generalized peritonitis in semi-urban and rural Nigerians.

To determine the pattern of antibiotic therapy and clinical outcome a prospective survey of all patients operated on for acute generalized peritonitis was undertaken. The male to female ratio was 1.7:1, and the mean age was 27.6 +/- 18.3 years. Operative findings were typhoid ilea perforation in 75 (38.1%), complicated acute intestinal obstruction in 44 (22.3%), complicated and uncomplicated acute appendicitis in 34 (17.3%), peptic ulcer perforation in 18 (9%) and traumatic intestinal injury in 11 (5.6%), representing the majority of the patients. A combination of chloramphenicol, gentamicin and metronidazole was given to 80 (40.6%), ampiclox, gentamicin and metronidazole to 72 (36.5%), ampiclox and gentamicin to 21 (10.6%) and other combinations to 5. A single antibiotic was administered in 13 (6.6%), that is clavulanate-amoxicillin, ampiclox, and cefuroxime. Antibiotics were changed in 37 patients (18.8%): to amoxicillin-clavulanate in 13, cefuroxime in 11, ceftriazone in 7, cefuroxime and metronidazole in 4 and amoxicillin-clavulanate and metronidazole in 2 patients. Postoperative complications were mainly wound infection in 105 (42.6%), wound dehiscence in 33 (16.7%), residual intra-abdominal sepsis in 19 (9.6%), residual intra-abdominal abscess in 17 (8.6%), postoperative chest infection in 14 (7%), incisional hernia in 11 (5.6%), anaemia in 6, faecal fistula in 5 and there was a mortality of 15.7%.
