Endovascular management of intracranial aneurysms at Chris Hani Baragwanath Academic Hospital.

Background: Worldwide, intracranial aneurysms are associated with a high mortality rate. While endovascular management has proven to be the choice of treatment in selected patients, patient demographics and aneurysm characteristics differ between study populations. Objectives: This study aimed to investigate the profile of patients with intracranial aneurysms who underwent endovascular management in the Interventional Neuroradiology Unit at Chris Hani Baragwanath Academic Hospital. Patient demographics, risk factors, indications, aneurysm characteristics and intra-operative complications were studied. Method: This was a 3-year retrospective study of all adult patients between 01 January 2018 and 31 January 2021. The Chi-square test was used to compare categorical variables. Results: A total of 77 patients were included in this study. The mean age of the patients was 47 ± 11.6 with a male-to-female ratio of 1:1.8. Hypertension was the most reported risk factor in 27% of patients. There was no statistical correlation between the gender groups according to presentation, multiplicity, aneurysmal size dimensions and locations. According to the presentation, there was statistical significance in ruptured intracranial aneurysms (p = 0.020), neck size dimensions less than 4 mm (p = 0.010), and aneurysms located in the internal cerebral artery (ICA) circulation (p = 0.001). Conclusion: The study findings support known parameters including females and anterior circulation aneurysm preponderance, and the low complication risk of endovascular management. Interestingly, intracranial aneurysms presented with rupture at smaller size dimensions. Contribution: This study provides valuable insights into intracranial aneurysm characteristics and endovascular management efficacy in a resource-limited setting.

The role of a multidisciplinary student team in the community management of chronic obstructive pulmonary disease.

OBJECTIVE: To determine whether a community-based, multidisciplinary team consisting of home-based caregivers and supervised students could improve the functional status and quality of life of patients living with chronic obstructive pulmonary disease (COPD) in a low-income, peri-urban setting in South Africa. METHODS: This was a quasi-experimental study conducted over three months. Attention was paid to health literacy, inhaler technique, respiratory conditioning and nutrition. RESULTS: Health literacy was poor and most patients were not using their inhalers correctly. Five of 12 patients found exercising challenging and withdrew from the study early. In the remaining seven patients, statistically significant improvements in FEV1%, and quality of life scores were seen at three months. Improvements in exercise tolerance and BODE prognostic index did not reach statistical significance. CONCLUSION: A home-based multidisciplinary student team can improve the functional status and the quality of life in patients living with COPD in a low-income setting. This approach offers a suitable model for community-based service learning.

An interinstitutional review of the value of FNAB in pediatric oncology in resource-limited countries.

Fine-needle aspiration biopsy (FNAB) has been widely accepted as a reliable diagnostic modality in the general pediatric population, but its role in pediatric oncology still remains elusive. With new treatment protocols subscribing to preoperative chemotherapy, the need for a quick, minimally invasive, and accurate diagnostic procedure has arisen. This study assesses the feasibility of FNAB in childhood malignancies to render a specific diagnosis on which treatment can be initiated. An 11-year retrospective study was done on FNABs in patients 19 years and under referred for clinically malignant mass lesions. Cases were confirmed with histology, immunocytochemistry, flow cytometry, or clinical follow-up. Of the 357 patients referred for FNABs, 36 patients were lost to follow-up and 31 FNABS were inadequate. A total of 290 cases were included in the study, of which 68 (23%) cases were benign and 222 (77%) were malignant. The most frequently occurring tumors were nephroblastoma (68), non-Hodgkin's lymphoma (39), rhabdomyosarcoma (22), Hodgkin's lymphoma (22), and neuroblastoma (22). The sensitivity of the procedure for neoplasia was 96.6%, the specificity 97.0%, positive predictive value 99.0%, and negative predictive value 90.1%, with a diagnostic accuracy of 96.7%. The ability of FNAB to enable a specific diagnosis to be made, that is correct and accurate subtyping of the tumor on which chemotherapy or radiotherapy could be commenced was 75.7%. This study shows that FNAB can be used with confidence to confirm malignancy in children. With clinicoradiological correlation and the aid of ancillary techniques, FNAB allows a rapid and accurate preoperative diagnosis for definitive therapy commencement in most cases.
