Volume of Acute Ischemic Stroke Lesion and Patients' Outcome at Jos University Teaching Hospital: A Cranial Computed Tomography Study.

BACKGROUND: Recent advances in ischaemic stroke care involve the use of antithrombotic and thrombolytic treatment options aimed at rescuing the salvageable brain tissue. Ischaemic stroke care in Nigeria is still a far cry from what's obtainable in advanced parts of the world where antithrombotic treatment options are being actively explored. A correlation of the volume of stroke lesion with patient outcome is a background for demonstrating the need for more tailored care to be studied in this part of the world. MATERIALS AND METHODS: Patients with acute ischemic stroke who had brain computed tomography scans within 7 days of symptom onset were recruited consecutively and followed up for one month to assess the modified Rankin Scale(mRS) outcome. Infarct volume measurement was correlated with the patient outcome using the student T-test, logistic and linear regressions. The collected data were analyzed with the Statistical Package for Social Sciences (SPSS) version 20.0. The statistical level of significance was set at P£0.05. RESULTS: One hundred and nine (109) patients were recruited with a mean lesion volume of 32.9cm3. Volumes of 26.0cm3 and 79.9cm3 were seen in patients alive versus dead at onemonth post insult with a P-value of 0.000, 13.6cm3 and 38.7cm3 seen in patients with favorable and unfavorable outcomes respectively on the modified Ranking Scale (P<0.009). Linear and logistic regression of lesion volume on outcome were both significant (P<0.000). CONCLUSION: Cranial CT measurement of Acute ischaemic stroke lesion volume correlates with the mRS assessment of patient outcome at one-month post insult.

Gastrointestinal Lesions in a Nigerian Tertiary Care Centre: A Histopathological Study.

BACKGROUND AND OBJECTIVE: Gastrointestinal diseases account for significant morbidity and mortality across the world. The study aims at establishing the epidemiological profile of gastrointestinal diseases in a Nigerian tertiary care center. METHODS: This is a descriptive retrospective study of all gastrointestinal specimens, submitted to the histopathology department of Delta State University Teaching Hospital (DELSUTH) for diagnosis. The age, sex, and histological diagnosis were extracted from the archives of the department. These were re-reclassified into diagnostic groups, analyzed using Excel spread sheet 2007 and summarized in tables. RESULTS: The study involves 570 patients (290 males and 280 females) with gastrointestinal tract (GIT) diseases within the age range of 10 days to 99 years, and of a mean age of 48.4 years. Congenital, inflammatory, benign neoplasms, malignant neoplasms and vascular diseases accounted for 1.6%, 77.5%, 2.6%, 18.1% and 0.18% of the cases respectively. These lesions were domiciled in the esophagus (1.4%), stomach (53.3%), small intestine (7.9%), appendix (10%), colorectum (25.4%) and anus (2%). The peak incidence corresponded to the 5th decade with 72.5% of cases affecting patients of 30-69 years. Malignant lesions were found in the esophagus (5.8%), stomach (14.6%), small intestine (4.9%), colorectum (72.8%) and anus (1.9%) and were mostly adenocarcinomas. CONCLUSION: The study showed that GIT lesions were slightly more common among males. Majority of cases were inflammatory diseases (gastritis, appendicitis) with GIT cancers (colorectal and gastric cancer) being the next most common. The preponderance of GIT lesions among the productive age calls for action to ameliorate the trend. Preventive public enlightenment campaign on GIT cancer risk factors and population-based screening programmes especially for Helicobacter pylori infection and colorectal cancer is highly recommended.

Radiological features of juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibroma is a rare nasopharyngeal tumour that presents with recurrent epistaxis. A case report and the role of radiologic imaging modalities in diagnosing this entity is presented.
