Influence of Adhesive Incise Drape Use on Surgical Site Infection Rates in Contaminated and Dirty Abdominal Operations.

BACKGROUND: Surgical Site Infection (SSI) remains the most common cause of Healthcare-Associated Infections (HCAIs). In particular, contaminated and dirty abdominal wounds are attended by a high rate of SSI which in turn is associated with a huge burden on patients, caregivers and the entire health care system. OBJECTIVE: To compare SSI rates following the use of iodine-impregnated adhesive incise drapes (Ioban) with routine conventional drapes in contaminated and dirty abdominal surgical wounds in a Nigerian tertiary hospital. METHODOLOGY: Consecutive, consenting adult patients who underwent laparotomy for cases classified as contaminated and dirty were prospectively enrolled in the study. Patients in the investigation arm had in addition to conventional drapes, iodine-impregnated adhesive incise drapes (Ioban) applied on the skin of the abdomen through which incisions were made, while patients in the control arm only had routine conventional drapes applied. All patients were followed up to 30 days after the operation. Surgical site infection rates were compared between the two groups. RESULTS: Sixty-two consecutive patients were enrolled into this study, of which 55 completed the 30-day follow-up. The mean ages of patients in the two groups were 37.96 ± 19.59 years and 36.74 ± 16.93 years (p=0.81). Males were 36 (65.5%) and females were 19 (34.5%). Overall, 30 (54.5%) patients had surgical site infection (SSI) in this study. Thirteen (46.4%) patients had SSI in iodine iodine-impregnated adhesive incise drape group while 17 (63%) patients had SSI in the conventional drape group, a difference that was not statistically significant (p=0.22). The most commonly isolated organism from infected wounds was Klebsiella species. CONCLUSION: The use of iodine-impregnated surgical incise drapes was associated with a lower, though non-statistically significant SSI rates compared to the use of conventional drapes. This marginal benefit will require a larger population study to examine its potential cost-effectiveness in our setting.

CONTEXTE: L'infection du site chirurgical (ISC) reste la cause la plus courante des infections associées aux soins de santé (IASC). En particulier, les plaies abdominales contaminées et sales sont associées à un taux élevé d'ISC, ce qui entraîne une charge importante pour les patients, les soignants et l'ensemble du système de santé. OBJECTIF: Comparer les taux d'ISC après l'utilisation de draps incisifs adhésifs imprégnés d'iode (Ioban) avec des draps conventionnels habituels dans les plaies chirurgicales abdominales contaminées et sales dans un hôpital tertiaire nigérian. MÉTHODOLOGIE: Des patients adultes consécutifs et consentants qui ont subi une laparotomie pour des cas classés comme contaminés et sales ont été inscrits de manière prospective dans l'étude. Les patients dans le groupe d'investigation avaient, en plus des draps conventionnels, des draps incisifs adhésifs imprégnés d'iode (Ioban) appliqués sur la peau de l'abdomen à travers laquelle les incisions ont été faites, tandis que les patients dans le groupe témoin n'avaient que des draps conventionnels habituels appliqués. Tous les patients ont été suivis pendant 30 jours après l'opération. Les taux d'infection du site chirurgical ont été comparés entre les deux groupes. RÉSULTATS: Soixante-deux patients consécutifs ont été inscrits dans cette étude, dont 55 ont terminé le suivi de 30 jours. L'âge moyen des patients dans les deux groupes était de 37,96 ± 19,59 ans et 36,74 ± 16,93 ans (p=0,81). Les hommes étaient au nombre de 36 (65,5%) et les femmes de 19 (34,5%). Globalement, 30 (54,5%) patients ont présenté une infection du site chirurgical (ISC) dans cette étude. Treize (46,4%) patients ont présenté une ISC dans le groupe avec draps incisifs adhésifs imprégnés d'iode, tandis que 17 (63%) patients ont présenté une ISC dans le groupe avec draps conventionnels, une différence qui n'était pas statistiquement significative (p=0,22). L'organisme le plus fréquemment isolé dans les plaies infectées était l'espèce Klebsiella. CONCLUSION: L'utilisation de draps incisifs chirurgicaux imprégnés d'iode était associée à des taux d'ISC plus bas, bien que non statistiquement significatifs, par rapport à l'utilisation de draps conventionnels. Cet avantage marginal nécessitera une étude avec une population plus importante pour examiner son potentiel de rentabilité dans notre contexte. MOTS-CLÉS: Plaies contaminées et sales, Drap incisif adhésif, Infection du site chirurgical (ISC).

Awareness and Knowledge of Breast Cancer and Breast Examination amongst Undergraduate Students. Mixed Method Approach.

INTRODUCTION: Breast cancer is the most common cause of cancer death amongst women, and the stage at presentation has been found to be an important prognostic index. The study aims to assess breast cancer awareness, including breast cancer education and knowledge of breast self-examination, among undergraduate students with the hope of improving their knowledge of breast cancer. METHODS: The study used the mixed method approach, to evaluate during breast cancer awareness month. All consenting participants completed a pre-test questionnaire before a breast health seminar, after which the post-test questionnaire was filled out. Consenting participants also had clinical breast examinations performed on them. The data were analyzed using IBM SPSS version 24. RESULTS: One hundred and thirteen participants filled out the pre-test questionnaire while 127 participants filled out the post-test. There was a significant change following the seminar. About 87.9% of respondents knew about breast cancer but had poor knowledge of the predisposing factors (11.3%). Most participants (94.3%) knew about self-breast examination (SBE), however, only 46% examined themselves in the past with only 21% aware of the correct timing for SBE. Clinical breast exams were conducted on 80 participants, six (7.5%) breast lumps were found and two had excision biopsies with histopathology diagnosis of fibroadenoma. CONCLUSION: Breast education is important, as knowledge about breast cancer is still low, even among undergraduate students. Continuous breast education should be encouraged.

INTRODUCTION: Le cancer du sein est la cause la plus fréquente de décès par cancer chez les femmes, et le stade de la maladie au moment de la présentation s'est avéré être un indice pronostique important. L'étude vise à évaluer la sensibilisation au cancer du sein, y compris l'éducation au cancer du sein et la connaissance de l'auto-examen des seins, chez les étudiantes de premier cycle, dans l'espoir d'améliorer leurs connaissances sur le cancer du sein. MÉTHODES: L'étude a utilisé une méthode mixte pour évaluer la sensibilisation au cancer du sein pendant le mois de la sensibilisation au cancer du sein. Toutes les participantes consentantes ont rempli un questionnaire de pré-test avant un séminaire sur la santé des seins, après quoi le questionnaire de post-test a été rempli. Les participantes consentantes ont également subi un examen clinique des seins. Les données ont été analysées à l'aide de la version 24 d'IBM SPSS. RÉSULTATS: Cent treize participantes ont rempli le questionnaire du pré-test et 127 celui du post-test. Des changements significatifs ont été observés à la suite du séminaire. Environ 87,9 % des personnes interrogées connaissaient le cancer du sein, mais avaient une faible connaissance des facteurs prédisposants (11,3 %). La plupart des participantes (94,3 %) connaissaient l'auto-examen des seins, mais seulement 46 % d'entre elles s'étaient déjà examinées et 21 % connaissaient le bon moment pour le faire. Des examens cliniques des seins ont été effectués sur 80 participantes, six (7,5 %) masses mammaires ont été trouvées et deux ont subi des biopsies d'excision avec un diagnostic histopathologique de fibroadénome. CONCLUSION: L'éducation mammaire est importante, car les connaissances sur le cancer du sein sont encore faibles, même chez les étudiantes de premier cycle. Il convient d'encourager la formation continue sur le cancer du sein. Mots-clés: Auto-examen des seins, Cancer du sein, Étudiantes de premier cycle, Méthode mixte.

Breast Cancer Stage at Diagnosis in a Nigerian Hospital: Trend over a Decade.

BACKGROUND: Breast cancer outcomes are poor in Nigeria, partly due to late-stage diagnosis. To assess the impact of past and present interventions, a review of an institutional data base was performed to determine the trend with respect to stage at diagnosis over a decade. METHODS: A retrospective analysis of an institutional data base was performed over a decade. The review period was divided into segments (2013-2015, 2016-2018 and 2019-2022). The latter period (2019-2022), corresponds to a time of more intense community interventions aimed at promoting early diagnosis and treatment around the locality of the teaching hospital. The stage at diagnosis within these periods were compared. The relationship between stage and sociodemographic variables (age, religion, marital status, menopausal status, and level of education) was assessed. RESULTS: There were 910 patients, 144 within the first period (2013-2015), 318 in the second (2016-2018) and 454 in the third period (2019-2022). The majority presented with stage 3 disease (73.8%). There was a significant decline in the proportion of metastatic cases and a concomitant increase in early cases in the latter part of the review. The proportion of metastatic cases reduced from 23.6% (2013-2015), to 15.7% (2016-2018) and 9.3% (2019-2022) (p=0.001). Level of education was significantly associated with stage (p=0.001). CONCLUSION: This study shows a trend towards downstaging of breast cancer in our locality. This trend corresponds to the period of more intense community interventions, justifying the need to further interrogate the direct impact of each of the interventions. This will provide a firm basis for sustaining or improving on current efforts to achieve more robust gains.

CONTEXTE: Les résultats du cancer du sein sont médiocres au Nigeria, en partie en raison d'un diagnostic tardif. Pour évaluer l'impact des interventions passées et actuelles, une revue d'une base de données institutionnelle a été réalisée pour déterminer la tendance en ce qui concerne le stade au moment du diagnostic sur une décennie. MÉTHODES: Une analyse rétrospective d'une base de données institutionnelle a été effectuée sur une décennie. La période de revue a été divisée en segments (2013-2015, 2016-2018 et 2019-2022). La dernière période (2019-2022) correspond à une période d'interventions communautaires plus intensives visant à promouvoir un diagnostic précoce et un traitement autour de la localité de l'hôpital universitaire. Les stades au moment du diagnostic au cours de ces périodes ont été comparés. La relation entre le stade et les variables sociodémographiques (âge, religion, état matrimonial, statut ménopausique et niveau d'éducation) a été évaluée. RÉSULTATS: Il y avait 910 patients, 144 dans la première période (2013-2015), 318 dans la deuxième (2016-2018) et 454 dans la troisième période (2019-2022). La majorité présentait une maladie de stade 3 (73,8 %). On a observé une diminution significative de la proportion de cas métastatiques et une augmentation concomitante des cas précoces dans la dernière partie de la revue. La proportion de cas métastatiques est passée de 23,6 % (2013-2015) à 15,7 % (2016- 2018) et 9,3 % (2019-2022) (p=0,001). Le niveau d'éducation était significativement associé au stade (p=0,001). CONCLUSION: Cette étude montre une tendance à la réduction du stade du cancer du sein dans notre localité. Cette tendance correspond à la période d'interventions communautaires plus intenses, justifiant la nécessité d'interroger davantage l'impact direct de chacune des interventions. Cela fournira une base solide pour soutenir ou améliorer les efforts actuels afin d'obtenir des gains plus robustes. Mots-clés: Sein, Cancer, Stade, Nigéria.

Laparoscopic Distal Pancreatectomy for a Large Multicystic Pancreatic Tumour in Ile-Ife, Nigeria: A Case Report.

BACKGROUND: Distal pancreatectomy is scarcely reported in Nigeria probably because the procedure is rarely performed. The use of laparoscopy for such a procedure is equally rare in our practice. METHODS: This is a report of a successful laparoscopic distal pancreatectomy carried out at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. REPORT: A 57-year-old male, known hypertensive-diabetic, who had been on antiretroviral therapy for ten years presented in our clinic with recurrent upper back pain. An abdominal CT scan revealed a multi-cystic mass in the distal pancreas with other normal intraabdominal organs. A 3-port laparoscopic distal pancreatectomy with splenectomy was carried out. The postoperative period was uneventful and the patient was discharged in good clinical condition on the second day. Histopathology report confirmed a benign multi-cystic epithelial pancreatic lesion. CONCLUSION: Laparoscopic distal pancreatectomy is feasible and was successfully carried out in our setting.

CONTEXTE: La pancréatectomie distale est rarement rapportée au Nigeria, probablement parce que l'intervention est rarement pratiquée. L'utilisation de la laparoscopie pour une telle procédure est également rare dans notre pratique. MÉTHODES: Il s'agit du rapport d'une pancréatectomie distale laparoscopique réussie, réalisée au Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. RAPPORT: Un homme de 57 ans, hypertendu-diabétique connu, sous traitement antirétroviral depuis dix ans, s'est présenté dans notre clinique avec des douleurs récurrentes dans le haut du dos. Un scanner abdominal a révélé une masse multicystique dans le pancréas distal avec d'autres organes intra-abdominaux normaux. Une pancréatectomie distale laparoscopique à 3 ports avec splénectomie a été réalisée. La période postopératoire s'est déroulée sans incident et le patient a été libéré en bonne condition clinique le deuxième jour. Le rapport d'histopathologie a confirmé une lésion pancréatique épithéliale multicystique bénigne. CONCLUSION: La pancréatectomie distale laparoscopique est faisable et a été réalisée avec succès dans notre cas. Mots clés: Pancréatectomie distale, laparoscopie, Nigeria.

Daytime Versus Night-Time Emergency Abdominal Operations: Perspective from a Low-Middle-Income Country.

BACKGROUND: Emergency abdominal operations carry significant risk of mortality and morbidity. The time of the day when such operations are performed has been suggested as a predictor of outcome. A retrospective comparison of outcomes of daytime and night-time emergency abdominal operations was conducted. METHODS: Clinical data of patients who had abdominal operations over a five-year period were obtained. Operations were classified as 'daytime' (group A) if performed between 8.00 am and 7.59 pm or 'night time' if performed between 8.00 pm and 7.59 am (group B). Post-operative outcomes were compared. RESULTS: A total of 267 emergency abdominal operations were analysed: 161 (60.3%) were performed in the daytime while 106 (39.7%) were performed at night. The case mix in both groups was similar with appendectomies, bowel resections and closure of bowel perforations accounting for the majority. Baseline characteristics and intra-operative parameters were similar except that 'daytime' operations had more consultant participation (p = 0.01). Mortality rates (13.7% in group A and 12.3% in group B, p = 0.2), re-operation rates (9.3% in group A and 10.4% in group B, p = 0.7) and duration of hospital stay (group A-11.1 days, group B-12.4 days p = 0.4) were similar. ASA status, re-operation and admission into the intensive care unit were identified as predictors of mortality. CONCLUSION: Timing of emergency abdominal operations did not influence outcomes. In resource-limited settings where access to the operating room is competitive, delaying operations till daytime may be counterproductive. Patients' clinical condition still remains the most important parameter guiding time of operation.

Exploring ways of Expanding access to minimal access Surgeries in Nigeria - A Review.

The practice of laparoscopy and other forms of minimal access surgery is currently limited in Nigeria, with only a few tertiary public and some private hospitals offering the services. There are several benefits of laparoscopy some of which are extremely important for patients in our setting and equally beneficial to our healthcare system. The different barriers to the practice are reviewed in this article and solutions proffered to enhance increased adoption of laparoscopy in surgical practice across the country. DISCLOSURE: An oral presentation of the abstract of this ndreview was made at the 102 Annual Clinical Congress of the American College of Surgeons held in Washington, DC, 16-20 October 2016.

Percutaneous Endoscopic Gastrostomy in Ile-Ife, Nigeria:An Initial Report.

BACKGROUND: Protein-energy malnutrition is a common problem in critically ill patient and it is a major cause of accelerated morbidity and mortality in this group of patients. Recent dramatic advances in both enteral and parenteral nutritional support have ensured that most of these critically ill patients are adequately nutritionally supported. Unfortunately, most of these advancements in nutritional supports are far from the reach of most patients in developing countries. In this report, we highlighted the indications, success, challenges of the use of percutaneous endoscopic gastrostomy (PEG) in Nigeria patients. PATIENTS AND METHODS: All cases of PEG performed at the Endoscopy Unit of Obafemi Awolowo University Teaching Hospitals complex, Ile-Ife, Osun State from January 2011 and June 2012 were recruited into the study. The data obtained included the sociodemographic parameters, indication and duration of the procedure, complications, and follow up. RESULTS: During the 18 months study period 645 upper gastrointestinal endoscopic procedures were performed. Majority [601(93.2%)] of the cases were for diagnostic purposes. Six (0.9%) cases of PEG were performed. Most (5 of 6) of the patients had central nervous system impairment while only one had severe chronic facial infection with naso-oral fistula. The median age of patients was 60.5 years. The entire procedure including endoscopy lasted an average of 25 minutes with a range of 12-35 minutes. Only one case had peristoma infection which resolved with antibiotics and repeated dressing with povidone iodine. There was no episode of aspiration pneumonitis or procedure related mortality. The average follow up was 6 months with variable weight gain during the follow up period. CONCLUSION: PEG is a simple, cost effective and safe method to rehabilitate nutritionally all chronically ill patients in less developed countries such as Nigeria. The need to increase awareness and acceptability of PEG among physicians managing such patients and the society cannot be overemphasized.

Histological Features and Tissue Microarray Taxonomy of Nigerian Breast Cancer Reveal Predominance of the High-Grade Triple-Negative Phenotype.

INTRODUCTION: Little is known about the biology, molecular profile and hence optimal treatment of African Nigerian breast cancer. The aim of this work, therefore, was to characterize the histology and molecular profile of Nigerian breast cancer. METHODS: Breast carcinomas from women at 6 centres of similar tribal origin in Nigeria were reviewed and assembled into tissue microarrays (TMAs), and sections were stained for hormone receptors, i.e. estrogen receptor (ER)α, ERß1, ERß progesterone receptor (PR) and androgen receptor, cyclin D, HER2, Ki67 and cytokeratins (CKs), i.e. CK5/6 and CK14 (basal) and CK18 and 19 (luminal). RESULTS: A total of 835 tumours were analysed. The mean age at diagnosis was 48.62 ± 12.41 years. The most common histological subtype was ductal NST (no-special-type) carcinoma (87.3%). Over 90% of the tumours were grade 2 or 3. The predominant molecular phenotype was the non-basal, triple-negative type (47.65%) followed by the HER2-positive group (19.6%). The percentage of ER-, PR- and HER2-positive tumours was 22.4, 18.9 and 18.8%, respectively. CONCLUSION: Nigerian breast cancer predominantly has a high-grade, triple-negative profile. It occurs at a younger age and bears similarities at the molecular level to pre-menopausal breast cancer in white women, with remarkably lower levels of ERß expression. The early presentation and histological and molecular phenotype may explain the poor prognosis, and tailoring treatment strategies to target this unique profile are required.

Non-surgical extraction of a massive sialolith in the Wharton's duct of a Nigerian.

BACKGROUND: Sialolithiasis is the most common salivary gland disorder characterized by calculi formation within the gland and/or its duct. The submandibular gland is most frequently affected due to the peculiar anatomy of the duct and the nature of its secretion. Varying sizes have been described for salivary calculi and unusually large sialoliths measuring above 3.5cm have been reported. Similarly, a few giant sialoliths have been reported in Africans. We therefore report the case of a large sialolith in the Wharton's duct of a Nigerian male. CASE PRESENTATION AND MANAGEMENT: A 54 year old Nigerian man presented with a hard, painless, left floor of mouth swelling of one year duration. There were recurrent episodes of moderate pain at meal times. Intraoral examination revealed a hard, mobile, non tender, creamy mass on the left side of the floor of the mouth protruding out of the Wharton's duct orifice. A lower occlusal radiograph revealed a large radio-opacity in the floor of the mouth and a diagnosis of left submandibular sialolithiasis was made. The sialolith was removed non-surgically and measured 4.4 cm by 1.8 cm. The patient was discharged and follow up period was uneventful. CONCLUSION: Large sialoliths are rarely reported in Africans, non-surgical extraction can be attempted for accessible and mobile sialoliths after full evaluation. Complex cases should be referred to the oral and maxillofacial surgeon.

Pattern and outcome of traumatic gastro- intestinal injuries in ile-ife.

AIMS AND OBJECTIVES: Trauma continues to assume a prominent role in the cause of disease in the developing world with increased westernization. This study highlights the pattern, management and outcome of gastrointestinal injuries following abdominal trauma in our hospital. PATIENTS AND METHODS: A descriptive retrospective study of all patients who had laparotomy following abdominal trauma at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife between January 2008 and April 2013. RESULTS: A total of 120 patients had laparotomy following abdominal trauma. Forty- five patients comprising 41 males and 4 females whose ages ranged between 14 and 65 years had gastrointestinal injuries. Majority (68.9%) were in the third and fourth decades with penetrating injury occurring in 55.6% .Causes of injury included gunshots (44.4%), road traffic accidents (37.8%), stabs (8.9%), falls (6.7%) and impalement (2.2%). The small intestine was the commonest site of injury (57.8 %) irrespective of the mechanism. Gut perforations accounted for 71.1% of all injuries. Two-thirds of patients had other associated injuries with retroperitoneal trauma being the commonest associated intra-abdominal injury. Majority (44.4%) had bowel resection and anastomosis with surgical site infection recorded in 35.6%. Overall mortality was 6.7% and this was significantly associated with pre-operative blood transfusion (p<0.05). CONCLUSION: Gut perforations from gunshot especially of the small intestine are the commonest gastro-intestinal injury in our setting. Pre-operative blood transfusion, perhaps indicating severity of injury, implies poor prognosis.

Expression of CD34 and maspin in ameloblastoma from a West African subpopulation.

Ameloblastoma is a locally invasive odontogenic tumor with a high recurrence rate. Its local invasiveness is aided by angiogenesis, which can be correctly estimated by CD34. On the other hand, maspin decreases the local invasive and metastatic capability of cancer cells and functions as an angiogenesis inhibitor. We aim to assess the association between maspin expression and microvessel density in ameloblastoma. Twenty-five formalin-fixed paraffin-embedded (FFPE) blocks of ameloblastoma cases were prepared for antibody processing to CD34 and maspin. Positive immunohistochemical staining was marked by brown cytoplasmic/membrane coloration for CD34 and by nuclear/cytoplasmic coloration for maspin. At the ×40 magnification, we counted blood vessels in two areas of dimension; 300 × 400 µm (area A) and 150 × 200 µm (area B) adjacent to the tumor region to assess relative dispersion of the vessels bordering the tumor. The overall approximate microvessel density (MVD) for area A = 11 (minimum 2, maximum 21) and that for area B = 5 (minimum 1, maximum 10). The MVD in the area A of plexiform ameloblastoma was similar to that of the unicystic, while the hemangiomatous variant had the highest MVD for area A. Maspin positivity was present only in the cytoplasm of ameloblast, stellate reticulum, and the fibrous connective tissue in varying proportions. There was no evidence of the anti-angiogenesis effect of maspin in ameloblastoma from this study. The significance of cytoplasmic localization of maspin in the ameloblasts and stellate reticulum cells needs further investigation.

Carcinoma head of the pancreas masquerading as hepatocellular carcinoma: a case report.

BACKGROUND: Cancer of the pancreas is the primary malignant tumour of the pancreas commonly seen in the elderly. Hepatitis B virus infection is not a known marker of the disease, but patient with carcinoma head of the pancreas presenting with epigastric mass with positive hepatitis B infection in the region of the world with high endemicity for hepatitis B virus infection may cause diagnostic pitfall. OBJECTIVE: To present a case of carcinoma head of the pancreas masqueradingas hepatocellular carcinoma METHODS: A review of the case note, autopsy findings including gross and microscopic examinations and literature was done. RESULTS: An elderly woman with history of weight loss and cigarette smoking.There was an epigastric mass and the liver was enlarged. The serum hepatitis B antigen was positive. Autopsy revealed an ill-defined mass in the head of the pancreas with metastasis to the liver. CONCLUSION: Things are not always what they seem.

Incidental finding of complete situs inversus in a polytraumatized adult.

BACKGROUND: Situs inversus is a rare abnormality typically posing a diagnostic dilemma during routine evaluation of acute abdominal emergencies such as in acute appendicitis and cholecystitis. It is rare to detect such in the setting of trauma. OBJECTIVE: To report an incidental finding of complete situs inversus in a poly-traumatized adult. METHODS: The clinical records of the patient including preoperative evaluation, intra-operative findings and postoperative care were reviewed. RESULT: A 53 year old man presented with difficulty breathing, left sided chest pain, generalized abdominal pain and distension 18 hours after a vehicular road traffic accident. Examination revealed features of left sided haemothorax, absent heart sounds, generalized peritonitis and limb injuries. Plain chest radiograph confirmed left haemothorax with dextrocardia. He had a left closed thoracostomy tube drainage and exploratory laparotomy which revealed complete situs inversus of intra-abdominal organs alongside a jejunal perforation which was repaired. Postoperative recovery was uneventful. CONCLUSION: Complete situs inversus is uncommon and may not be anticipated in evaluation of trauma patients. Preoperative clinical and radiological evaluation may however be helpful in making a pre-operative diagnosis and further management.

Torsion of wandering spleen, an unusual cause of acute abdomen; a report of two cases.

BACKGROUND: Wandering spleen is an uncommon entity that is rarely considered in the evaluation of patients with acute abdominal conditions. OBJECTIVE: To report two cases of wandering spleen presenting with acute abdominal pain. METHODS: The clinical records of the patients including preoperative evaluation, intra-operative findings and postoperative care were reviewed RESULT: A 6 year old boy presented with right lumbar pain which worsened over a 36 hour period with findings of a tender right lumbar mass. Abdominal ultrasound showed a mass with echogenicity consistent with that of the spleen with no blood flow and an empty splenic bed. The pre-operative diagnosis was torsion of a wandering spleen. The second case was that of a 42 year old woman who presented with severe colicky lower abdominal pain which worsened over three days with a background history of progressively increasing lower abdominal mass which was tender and about 26 week gestational size at presentation. The initial diagnosis was torsion of an ovarian cyst. Abdomino-pelvic Ultrasound scan showed a heterogeneously hypo-echoic mass overlying the uterus and the left ovary with no blood flow. The presence of wandering spleen with torsion of the vascular pedicle was confirmed at laparotomy in both instances. Splenectomy was performed in both cases with good recovery. CONCLUSION: Torsion of a wandering spleen poses a diagnostic challenge. A high level of suspicion is required to make a diagnosis and institute appropriate treatment.

Oro-facial sarcomas: a review of 88 cases in a Tertiary Institution in Nigeria.

BACKGROUND: A sarcoma is a malignant tumour arising from connective tissue. The word sarcoma is derived from the Greek word, sarkoma meaning fleshy growth and presents either as a soft tissue or bony tumour. Sarcomas are rare in the oro-facial region compared to oral squamous cell carcinoma. The rarity of jaw sarcomas makes diagnosis sometimes challenging and the anatomy makes aggressive treatment difficult without causing unacceptable physiological, functional and cosmetic damage to the patient. The aim of this study was to examine the demographic pattern of patients with jaw sarcomas seen at the University College Hospital, Ibadan, Nigeria over a thirty year period. METHODS: All histologically diagnosed cases of sarcomas of the oro-facial region from the Cancer Registry of the University College Hospital Ibadan and the histology records of the department of Oral Pathology, University College Hospital Ibadan from 1980-2010 were reviewed. Data was analyzed using SPSS version 18. RESULTS: Eighty eight oro-facial sarcomas were seen consisting of sixteen different histological types. Osteogenic sarcoma was the most common type with 40 cases (45.5%). Osteogenic sarcoma occurred more in females than males with a male: female ratio of 13:27 and a mean age of 32.2 years (SD ± 15.7). Embryonal rhabdomyosarcoma had an equal male: female distribution with mean age of 7.0 years (SD ± 5.2) and peak age incidence in the first decade. CONCLUSION: The findings in this study were generally in agreement with reports from Europe, and though, at variance with some African studies, they are mostly in agreement with large African series.

CONCLUSION: PEG is a simple, cost effective and safe method to rehabilitate nutritionally all chronically ill patients in less developed countries such as Nigeria. The need to increase awareness and acceptability of PEG among physicians managing such patients and the society cannot be overemphasized.

Stages of delay in oral cancer care evaluated at a tertiary health centre.

BACKGROUND: To examine the stages of delay in presentation and management of oral cancer patients at University College Hospital Ibadan and compare findings with previous studies. METHODS: A 20-year retrospective analysis of the delay stages among oral cancer patients that utilized patient's biodata and clinical data. RESULT: 169 oral cancer cases consisting of 127 carcinomas, 25 sarcomas and 17 lymphomas were analyzed. There was significant difference in the mean evolution time (ET) according to histological type (oral carcinoma = 282.8 +/- 414, oral sarcomas = 219.2 +/- 247.3 and oral lymphomas 105.5 +/- 115 days; p = 0.001). Patient's delay was more than professional delay for all cancer types (65.9%, 59.1% and 60.1% for carcinomas, sarcomas and lymphomas respectively). There was a significant difference in the mean ET of the early stage cancers compared with the late stage cancers (mean = 137.2 +/- 99 and 266.4 +/- 355; p = 0.010). CONCLUSION: A combination of patients and professional delay negatively influenced the management of oral cancer patients but the patient's delay formed the bulk of this combination in our center.

Gross surgical features and treatment outcome of ameloblastoma at a Nigerian tertiary hospital.

BACKGROUND: Ameloblastoma is a benign odontogenic tumour which is locally infiltrative and may cause severe craniofacial deformities. Its epidemiology, clinical and histologic configurations are replete in local and international literature, but data about its gross surgical patterns and treatment outcome in Nigeria is sparse. We therefore describe the clinical, gross surgical configuration, histopathologic features and the outcome of management seen at a Nigerian tertiary hospital. METHODS: Records of all histologically diagnosed Ameloblastoma from January 2000 to December 2011 at the University College Hospital, Ibadan, Nigeria, were retrieved from the departments of Oral and Maxillofacial Surgery and Oral Pathology. Patients' biodata, clinical, radiographical, gross surgical and histological features of the tumours, type of treatment, mode of jaw reconstruction and post-surgical follow up period data were documented. RESULTS: One hundred and sixty-three ameloblastomas were diagnosed during the study period, only 92 had complete records and were therefore included in the study. The mean age was 34.2 years (+/- 14.25) and the male to female ratio was 1:1.1. Majority of the patients were in the low socioeconomic class (67.4%). Majority of the patients (76.5%) had segmental jaw resection and reconstruction was done mainly with non-vascularised iliac crest grafts. The gross surgical configurations were described as solid, cavitated and cystic. CONCLUSION: Despite the locally aggressive nature of ameloblastoma, patients presented late for treatment and majority of them had segmental jaw resection as a mode of treatment. Three gross surgical configurations of the specimens were described.

Histological grading of oral squamous cell carcinoma patients in Ibadan using Bryne's and Broders' grading systems--a comparative study.

BACKGROUND: Several histological grading systems for oral squamous cell carcinoma (OSCC) have been used previously to guide treatment and prognostication, amongst which are the Broders and the Bryne's methods. The Bryne's invasive tumour front (ITF) protocol has been adjudged to have good prognostic significance. We compared the use of Bryne's ITF system and Broders' grading system in grading OSCC at our centre in relation to clinico-demographic profile of patients. METHODS: Thirty two formalin fixed paraffin embedded (FFPE) tissue samples of histologically diagnosed OSCC patients at the University College Hospital (UCH) Ibadan were selected, demographic data and site of lesions were retrieved from the medical records of the patients. The haematoxylin and eosin (H&E) slides of the 32 cases were prepared and evaluated using Bryne's ITF system and Broders classification. RESULTS: Using Bryne's system, 28% of the cases had a high malignancy score while 72% had a low malignancy score. The high malignancy score lesions were most commonly seen in the palate (15.5%). Also Broders classification showed that 31.3% of cases were well differentiated tumours, 50% were moderately differentiated while 18.7% were poorly differentiated. CONCLUSION: Either the Bryne's system or Broders classification can be used to grade OSCC with similar results being obtained.

Adulthood hirschprung's disease: a report of 4 cases in Ile-Ife. Nigeria.

BACKGROUND: Hirschsprung's disease in adulthood is very rare and is often misdiagnosed. We present four cases of adulthood Hirschsprung's disease seen in the last two decades to illustrate challenges accompanying its diagnosis and management. METHOD: This descriptive case series included cases of histologically proven Hirschsprung's seen in adulthood at the Obafemi Awolowo University Teaching Hospitals Complex in the last two decades (1991-2011). The clinical data, radiological investigations, details of surgical treatment, histological diagnosis, outcomes and complications were analyzed. RESULT: There were 4 adult patients, 3 males and 1 female with age ranging from 17 to 74 years (mean 23 years). Each patient presented with sub acute intestinal obstruction needing two staged procedures of initial colostomy followed by definitive procedure of low anterior resection (State procedure) in 3 patients and Swenson-Bill procedure in one. There was one mortality and good long term outcome in the remaining three. CONCLUSION: This review presented the oldest patient presenting with adult Hirschsprung's and the highest mean age of any case series. Four patients with adulthood Hirschsprung's disease managed by two operative procedures enabled comparison of operative outcome with respect to complications and functional outcomes. Mortality seems to correlate with presentation at old age, which is usually due to life long self-management of chronic constipation. Though very rare, a high index of suspicion of adulthood Hirschprung's disease should be maintained in adult patients with recurrent chronic constipation needing lifelong laxative, enema or mechanical wash-out.
