- ItemOpen AccessUltrasonic dimensions of normal pancreatic duct in healthy Nigerians(2007) Olowoyeye, Omodele; Arogundade, RA; Awosanya, GOGThe pancreas, apart from its endocrine function, principally contains exocrine acinar cells, which constitute about 80% of the gland, secreting pancreatic enzymes via a network of ducts. Ultrasonography is readily available, affordable and radiation-free, thus constituting a frontline imaging modality in the evaluation of pancreatic ducts. This study aims to establish normal sonographic pancreatic duct dimensions in asymptomatic adult Nigerian population. A total of 400 adult male and female subjects who underwent abdominal ultrasonography to evaluate clinical conditions unrelated to the pancreas were studied prospectively between April 2002 and May 2004. The measured anterior-posterior diameters of the pancreatic ducts in the region of the body were recorded and analyzed. The mean diameter of the pancreatic duct diameter in 87.76% was 2.13mm ± 1.35 SO and a range between 1.6-2.5mm. The pancreatic duct diameter increased with age indicating statistically significant relationship. (p-value=0.0492). Measurements of the normal pancreatic duct diameter in this study agrees with previous work documented in literature. Knowledge of the normal diameter of the pancreatic duct and variation factors are important for ease of identification of abnormalites during ultrasound evaluation of the pancreas.

- ItemOpen AccessEffects of Ascorbic Acid Intake on the Intima-Media Thickness and Blood Flow Velocities of the Carotid Artery in Patients With Sickle Cell Anemia(2011) Olowoyeye, Omodele; Jaja, SI; Kehinde, MO; Awosanya, GO; Irurhe, NK; Adeyomoye, AA; Soyebi, KO; Arogundade, RA; Adekunle, OM; Soneye, BK; Tubi, OOThis study aims to investigate and compare the effects of six-week oral vitamin C supplementation on blood velocities, intima-media thickness, and cross-sectional diameter (CSD) of the common carotid artery of sickle cell anemia (SCA) and non–sickle cell anemia (NSCA) subjects using sonography. Results showed that the CSD and end-diastolic velocity were significantly higher (P < .002 and P < .001, respectively) in the SCA subjects than in the NSCA subjects in the presupplementation phase. Calculated resistivity index (RI) was significantly lower in the SCA subjects (P < .003). Vitamin C supplementation had a slight effect on all the measured parameters in the NSCA subjects but caused a significant increase in peak systolic velocity (PSV) (P < .02) and RI (P < .01) in SCA. A comparison of change in each measured variable between the groups showed significant differences. Oral supplementation with vitamin C should be encouraged in patients with SCA as prophylaxis against endothelial damage, thereby preventing vaso-occlusive crises and their associated morbidity.
- ItemOpen AccessCommon Factors Affecting Radiographic Diagnostic Quality in X-Ray Facilities in Lagos(2012) Edeh, VI; Olowoyeye, OA; Irurhe, NK; Abonyi, LC; Arogundade, RA; Awosanya, GOG; Eze, CU; Omiyi, ODObjective: To determine the common factors that affect the diagnostic quality of radiographs in radiodiagnostic centers in Lagos state, Nigeria. Methods: Self-administered questionnaires containing both open and close-ended questions were distributed to the supervising radiographers in radiodiagnostic centers within the Lagos metropolis. The questions asked included the film/reject ratio in each center and reasons why each film was rejected. Results: Faulty x-ray machines, movement on the part of the patient, poor darkroom film processing, and suboptimal radiographic techniques were the main reasons respondents identified as factors commonly responsible for the production of faulty films. In some cases, more than one of these factors was responsible. Conclusion: There is a need to routinely ensure that x-ray machines are properly calibrated in order to reduce the rate of film rejects in our x-ray facilities. In addition, equipment that is old and cannot be properly calibrated should be replaced. This would guarantee optimum performance and reduce radiation dose to patients and personnel. Younger radiographers should also be open to mentoring by older colleagues so they can acquire useful tips on how to reduce the production of films with unacceptable diagnostic quality. They should be encouraged to attend continuing education programs for improved expertise. Also, quality control and maintenance programs such as the reject film analysis or regular equipment maintenance should be enforced in radiodiagnostic centers.

- ItemOpen AccessKnowledge and awareness of breast cancer among female secondary students in Nigeria(2012) Irurhe, NK; Raji, SB; Olowoyeye, OA; Adeyomoye, AA; Arogundade, RA; Soyebi, KO; Ibitoye, AZ; Abonyi, LC; Eniyandunni, FJCarcinoma of the breast is the leading cause of death in women aged 30 years and above. It reduces the life expectancy of the population at risk especially those between 31 and 50. The incidence of breast cancer is rising rapidly in the population group that used to enjoy low incidence of the disease. Majority of the patients present late in the hospital. It is therefore pertinent to assess the level of awareness and knowledge of breast cancer. The purpose of the study was to assess the level of awareness and knowledge of breast cancer as well as breast self examination among secondary school students. The study was a cross-sectional survey amongst students of three secondary schools in Nigeria. Each respondent was given a self administered questionnaire.194 (97%) heard of breast cancer before, 61(30.5%) mentioned radio/television as the first source of information. Knowledge of respondents was low. In conclusion majority of the respondents had heard of breast cancer but the knowledge and understanding of the disease was very low.
- ItemOpen AccessCompliance Rate of Adequate Filling of Radiology Request Forms in a Lagos University Teaching Hospital(2012) Irurhe, NK; Sulaymon, FA; Olowoyeye, Omodele; Adeyomoye, AARadiology request forms are essential communication tools used by hospitals and doctors referring patients for radiological investigations, however, their importance is highly underestimated. The clinician is required to give brief clinical history by filling the reason for referral as this helps radiologists to better understand the patient’s condition; so that the required expertise can be utilized. The aim of the research is to evaluate the adequacy of patient data and clinical information filled in the request forms sent to the Radiodiagnosis Department by the referring clinicians. Descriptive study design was used to find out the compliance rate of filling radiology request forms as indicated by referring physicians. The average number of request forms received on a daily basis in the Radiodiagnosis department of Lagos University Teaching Hospital (LUTH) was 62. A non probabilistic Quota sampling method was used to select 300 request forms over a period of 3 months which are representation of variety of examinations from different departments within LUTH. The study revealed a relatively high number of uncompleted fields in the radiology request forms in LUTH.
