Radiological features of ulcerative colitis in a Nigerian: a case report

Ulcerative colitis is an inflammatory disease of the colon with unclear cause. It is common in the Jewish and European population but rare in blacks Methods: The medical records of the patient who presented with ulcerative colitis and literature review of the case using available journals and pubmed search was employed. The radiological imaging and laboratory results were reviewed Conclusion: There is need to include radiological imaging and to have high index of suspicion of ulcerative colitis in patients presenting with gastrointestinal signs and symptoms among black populations

Estimation of the Heat Flow Variation in the Chad Basin Nigeria

Wireline logs from 14 oil wells from the Nigerian sector of the Chad Basin were analyzed and interpreted to estimate the heat flow trend in the basin. Geothermal gradients were computed from corrected bottomhole temperatures while the bulk effective thermal conductivity for the different stratigraphic units encountered in the wells were computed from the sonic logs data. The heat flow values were then calculated. A corrected average geothermal gradient of 3.4 oC/100 m and a regional range of 3.0 to 4.4 oC/100 m were obtained. A porosity range of2 to 79 % and average of 35 % were computed for Chad Basin Nigeria. Also the thermal conductivities vary from 1.70 and 3.11 Wm-1 oC-1, with an average value of 2.35 Wm-1 oC-1 computed for the various wells in the basin. A large variation in heat flow was recorded within the basin. Mean heat flow values computed for the basin vary from 63.6 to105.6 mWm-2, with a simple average of 80.6 mWm-2. Although there is no distinct trend on heat flow within the basin, the computed heat flow values are relatively lower at the southwestern and northeastern axis of the basin. And the values obtained in this study compared favorably with those of other world sedimentary basins (including NigerDelta) that are of similar history with the Chad Basin, suggesting that the Nigerian Chad Basin is a possible petroliferous basin

Computerized tomographic pattern of stroke seen in University of Portharcourt Teaching Hospital

Background: Data on Computed tomographic (CT) pattern of stroke abound in literature but they are predominantly from studies done in the Western world.Though most of the reports agree that ischaemic rather than haemorrhagic stroke is prevalent in most climes,no strictly radiology based study can be quoted in the Port Harcourt area.Thus there is the need for accurate data on stroke pattern in Nigerians of the South-South region.Aims: This study was done to establish the CT pattern of stroke seen in University of Port Harcourt Teaching Hospital (UPTH) and to determine the relationship between the different stroke patterns and age, sex, including time of presentation.Methodology: A prospective study of 203 subjects with clinical diagnosis of stroke who had CT of the brain performed during a 12month period (November 2012 to November 2013).A 2-slice helical CT was used to obtain images in the axial plane. Images were classified as normal or abnormal scans.Abnormal scans were analyzed as ischaemic infarcts, intracerebral haemorrhage, subarachnoid haemorrhage (SAH), subdural haematoma, abscess, neoplasm, meningitis,and cerebral atrophy.The clinical diagnosis, age, sex and time of presentation of the patients were recorded. Statistical analysis was done with the Statistical Package for the Social Sciences (SPSS) software version 20.0.Means were compared using Student's t test. Pearson's correlation coefficient was used to correlate CT findings with clinical diagnosis,age,and sex.P values < 0.05 were considered significant.Results: The age distribution of the study population ranged from 6-90 years with a mean of 58.3+14.9years. The over 70 age group was most frequent with 24.1% of the subjects. Males were predominant at 51.7% of the sample size.Findings of ischaemic cerebrovascular disease (CVD) were more common than haemorrhagic CVD at 63.2%.Conclusion: This study revealed a higher incidence of ischaemic stroke compared to haemorrhagic stroke.Keywords: Computed tomography;Cerebrovascular disease;Ischaemic stroke;Haemorrhagic strok

Pattern of metastatic deposits of malignant neoplasms to the chest seen on plain chest radiographs in Port Harcourt

Background:  Plain chest x-ray (CXR) is a veritable tool in the survey of metastases to the lung. It is important to recognize radiographic signs of metastatic deposits to the lung and the emergent trend of the distribution of metastases in our environment. Primary cancer can also be determined to some extent by the radiographic appearance on the chest radiographs. Aim: To describe radiographic appearances of metastases to the chest in order to add to existing literature and make recommendations for improved patient care.Methods:  A prospective study of 240 patients diagnosed with carcinomas/sarcomas of different organs and confirmed by histology from January 2008 to October 2010. Biodata, diagnosis and radiographic findings were recorded. Data was analysed by descriptive statistics.Results: Of 240 patient's chest radiographs with evidence of metastases. Age ranges were 5 to 75 years with an average age of  45.3 years and a male to female ratio of 1:1.2. One hundred and forty-four (60%)   showed   multiple rounded opacities, 48(20%) pleural effusion, 24(10%) as lytic lesions of the ribs, 6(2.5%) as sclerotic lesions on the ribs, twelve (5%) as streaky shadows and 6(2.5%)  as miliary shadows. Breast cancer was the commonest cause of metastasis seen in 80(33.3%) patients. The least was  osteosarcoma [3(0.1%)]. The lower zone was the commonest site of metastases [118(49.2%)] followed by the  mid zone [74(30.8%)].Conclusion: Multiple rounded opacities are the commonest findings on CXR. Metastases  were  common from breast, prostate, thyroid and cervix Rare from osteosarcoma  and melanoma. CXR is recommended for initial evaluation of cancer patients

Effect Of Alum On The Proximate Composition Of Raw African Breadfruit (Treculla africana)

The proximate composition of breadfruit seed parboiled with various alum concentrations of 0%, 0.4%, 1.2% and 2% were evaluated respectively. Results showed that moisture content increased (18.35%, 18.65%, 20.55%). Crude protein decreased with alum concentration (17.63, 16.18, 15.91 and 15.68). Crude fibre increased steadily (1.55, 2.95, 2.98, 3.40). Ash and crude fat showed no significant difference.
