Item Factors influencing the pratcie of hydrostatic reduction of intussusception amongst radiologists in a developing country(2009) Lawal, T. A.; Atalabi, O. M.; Adekanmi, A. J.; Ogundoyin, O. OBackground: Intussesception is a mojor cuase of intestinal obstruction in children and can be treated operatively or non-operatively. Surgery is associated with mortality rates, in dveloping countries of 8.5% to 18%. Hydrostatic reduction is a cost effective treatment that can lower the mortality rate in resource poor settings. However, the teachnique is not widely performed inspite of the advantages. Objectives: We reviewed factors influencing the current practice of hydrostatic reduction of intussusception by radiologists in Nigeria. Materials and Methods: A survey of radiologists was conducted using structured self adminsitered questionnaires. Strenght of assocition between the practice of hydrostatic reduction and variables related to the workforce was evaluated using Fisher's exact test. Result: Fifty-one participants were studied. Three (18.8%) hospitals have at least one consultant radiologist focusing on pediatric surgeon or more. Hydrostatic reduction is practiced in hospitals with a radiologist with interest in pediatric radiology, (p=0.002). Lack of expertise was given as the main reason why hte other hospitals have not commenced the procedure.Item The yield from routine chest X-rays in stage 3 breast cancer patients(2008-04) Agunloye, A. M; Elumelu, T.; Adenipekun, A.,; Atalabi, O. M.Context: Cancer of the breast is a common malignancy in Nigeria women and various imaging examinations, including the chest radiograph are routinely requested in all patients with this disease. Objective: The objective of the study was to determine the positive yield from routines chest radiographs in Nigeria patients with locally advanced stage 3 breast cancers but who had no clinical symptoms or signs of plumonary or pleural metastatic disease. Methods: This descriptive retrospective study evealuated clinical records and chest radiographs of 61 female Nigerian patients with local stage 3 historically diagnosed breast cancers, who presented at the radiotherapy unit of the University College Hosiptal, Ibadan, over a 12 month period. All abnormalities on the chest radiographs were documented. Results: The ages of the study group ranged from 25 to 67 years with a mean of 47years. Fourty-seven (77%) of the patients had normal chest radiographs. Of the 14 abnormal radiographs, bilateral lung parenchymal metastases were seen in 4 cases one of whom also had bilateral pleural affusion. Other abnormal findings included hilar adenopathy, right lower lobe collapse, lymphagitis carcinomatosis and cardiomegaly. Conclusion: The authors conclude that a 23% detection rate from thses screening chest radiographs is high and should be recommended as over 70% of Nigerian patients with breat cancers present with advanced tumors.Item Bilateral tardus-parvus waveform in kidneys secondary to mid-aortic syndrome in a hypertensive child(2008) Atalabi, O. M.; Lee, E. Y.Item Clinicoradiologic and sonographic patterns of metastasis in hepatocellular carcinoma(2006) Otegbayo, J. A.; Atalabi, O. M.; Yakubu, A.Hepatocellular carcinoma(HCC) is usually diagnosed at an advanced stage, when little remedy could be offered. There is a need for relatively affordable, available and non- invasive tests for diagonsis, staging and detection of metastasis among individuals at risk. A clinical, chest radiographic (CXR) and abdominal ultrasonographic examination was carried out to detect and evaluate the pattern of metastasis among 53 untreated patients. One patients had clinical paraparesis with no outward evidence of metastasis. CXR revealed lund metastasis in 11(20.8%), with multifocal deposit in one. Two (3.8%) patients had perihilar lymphadenopathy and consolidation, respectively, while 18 (34%) patients had elevated right hemidiaphragm and four (7.5%) had pleural effusion. One right hemidiaphragm and four (7.5%) had pleural effusion. One had right basal pneumonitis, multiple cavitatory lesions in the lungs fields and soft-tissue wasting. No abnormality was seen in 17 (32.1%) cases. Abdominal ultrasonograph showed probe tenderness in 22(41.5%), hepatomegaly in 49(92.5%), with 33(62.3%) of these having nodularities of varying sizes. The spleen was enlarged in 10(18.9%) cases, with para-aortic lymphadenopathy. Portal hepatic lymphadenopathy was demostrated in two (3.8%) cases, while pleural effusion was detected in seven (13.2%). Metastasis is common in HCC at presentation, the lung is the commonest site of spread. Clinically visible metastasis appears uncommon in HCC.Item Renal Length, packed cell volume and biochemical parameters in subjects with chronic renal failure: a preliminary report(2006-12) Salako, B. L; Atalabi, O. M.; Amusat, A. M.; Adeniji-Sofoluwe.The constellation of laboratory and imaging findings that distinguish progressive chronic kidney disease (CKD) from acute renal failure are bilaterally small kidneys, elevated PTH, creatol, carbamylated haemoglobin levels, anaemia, hyperphosphataemia and hypocalcemia with elevated parathyroid hormone levels, and a urinary sediments that reveal proteinuria and broad casts. There has been a documented significant correlation between renal legth and GFR, but, the relationship between length and other ureamic and biochemical parameters is still unclear. This study assessed the relationship between renal length and serum biochemistry among chronic renal failure and patients seen at the University College Hospital, Ibadan. Patients withchronic renal failure who presented for the first time in predialytic phase were recruited.Renal ultrasound was used to assess renal length and based on this subjects were classified into those with shrunken kidneys and those with normal kidneys. Blood chemistry including PCV, serum urea and creatinine were performed. Creatinine clearance was calculated using Gault and Cockroft equation. The data were processed using the Statistical Package for the Social Sciences (SPSS) by comparing the means of biochemical parameters of the two groups. Twenty-one patients completed the study; there were 14males and 7 females with age range between 24-72 years, means age of 44.2 (15.4SD) years. Thriteen (61.9%) of them haad kidney length in the abnormal rannge (less than 9cm). No patients had enlarged kidneys. Majority of the patients in this study had bilateral shrunken kidneys but there were no correlations between kidney length and serum creatinine, urea, PCV and creatinine clearance.Item Computed tomography and childhood seizure disorder in Ibadan(2004-04-06) Obajimi, M. O; Fatunde, O. J.; Ogunseyinde, A. O.; Omigbodun, O. O.; Atalabi, O. M.; Joel, R. U.Background: Computed Tomography (CT) is an important tool for neuroimaging, it offers an opportunity to investigate structural lesion as a cause of seizures with little morbidity. This study is designed to evaluate its's applicability in children with epileptic seizures. Method: It is a descriptive study of the CT scans of the 103 consecutive children who were referred to the CT suite of the University College Hospital on account of seizure disorders over a 5 year period (1997-2001). Results: Only 103 (4.6%) of the subjects who had cranial scans done in five years were children with seizures disorders. The CT scans were abnormal in 53 (51.5%). Hydrocephalus was the most common finding in 14(13.6%). Cerebral atrophy and infarct were reported in 10.6% and 8.7% respectively. the outlined cranial fractures found in 6.8% were all depressed. A high incidence (74.4%) of abnormal scans was reported in the children with partial seizures. Thirty-three (62.3%) of the abnormal scans were amenable to surgery. The presence of neurologic deficit increased the yiled of abnormal CT features. Conclusion: CT scans are extreme value in the screening and difinitive evaluation of seizures in children. It is advocated for excluding treatable conditions and monitoring progression of the disorder.Item Cranial computerrized tomography in the evaluaaton of stroke patients in Ibadan(2003-12) Ogunseyinde, A. O; Atalabi, O. M.206 patients clinically diagnosed as stroke/cerebrovascular accidents (CVA) were investigated using computerized tomography (CT) scan. 19 patients(9%) had normal scan, while 20(9.7%) patients had other lesions including atrophy and tumours. Of the 167 (18.1%) patients proven to have suffered a cerebro-vascular accidents (CVA/ stroke), 73(43.7%) were haemorrhagic, 92(55.1%) were infarcts; and left side when it is heaemorrhagic than infarct (16.7%;38.3). The parietal and frontal lobes were affected when lesions occur in single site while caudate nucleus, putamen and ventricles are commonly affected when lesion is in more that 2 sites. The occipital lobe i.e. posterior cerebral artery territory is infrequently involved.Item Rigid retrograde endoscopy under regional aneasthesia:a novel technique for the early realignment of traumatic posterior urethral disruption(2002) Olapade-Olaopa, E. O.; Adebayo, S. A.; Atalabi, O. M.; Popoola, A. A.,; Ogunmodede, I. A.Item Case report-Abdominal cocoon(WAJM, 2001-10-12) Irabor, D. O; Atalabi, O. M.Abdominal cocoon is a rare cause of acute intestinal obstruction seen almost exclusively in young adolecent females. Almost all cases are diagosed at surgery and cured by excising the fibrous cocoon. This case although diagnosed accidentally too was treated conservatively successfully.Item Accidental ingestion of a drawing pin a case of an unusal foreign body in the Oesphagus(2001) Agunloye, A.
