Background:The concept of modern neuro-oncology hinges on strategic innovation and refinement of procedures with the intention to enhance safety, optimize extent of tumor resection, and improve not only survival but also the quality of life as well. One of such refinements includes same-day hospital admission, as well as early discharge following brain tumor surgeries. The latter has been further stretched to same-day discharge in particular settings to reduce the risk of nosocomial infections, cut brain tumor surgery costs, and improve patients’ satisfaction. We highlight the challenges and possible benefits of outpatient craniotomy in a sub-Saharan African setting portrayed by the presence of lean resources and a predominant “out of pocket” health-care financing.Case Description:Outpatient craniotomy was performed in two selected patients harboring intra-axial tumors: a right temporal low-grade glioma and a left frontal metastasis. The clinical outcome proved successful at short- and long-term in both patients; complications related to surgery and same-day discharge were not reported.Conclusion:Outpatient craniotomy is practicable and safe in resource-challenged environments and can further make brain tumor surgery cost effective and acceptable in carefully selected patients. Further prospective studies in similar settings but involving larger groups of patients are warranted.
OBJECTIVE Africa contributes significantly to the global neurosurgical disease burden but has only 1% of the neurosurgery workforce. This study appraises the neurosurgical workforce and training capacity in Africa and projects the workforce capacity by 2030. METHODS The authors conducted a systematic review of the online literature on neurosurgical workforce and training in Africa obtained from three journal databases (PubMed, Embase, and African Index Medicus), as well as from a gray literature search, between September and December 2020. Included literature passed a two-level screening conducted using a systematic review software by a team of two independent reviewers. Data were extracted from selected articles and documented and analyzed on spreadsheets. RESULTS One hundred and fifty-nine eligible articles were analyzed: 1974 neurosurgeons serve 1.3 billion people in Africa (density 0.15 per 100,000 persons, ratio 1:678,740), with uneven distribution between the regions. North Africa has 64.39% of the neurosurgical workforce (n = 1271), followed by Southern Africa (12.66%, n = 250), West Africa (11.60%, n = 229), East Africa (8.26%, n = 163), and Central Africa (3.09%, n = 61). At an exponential growth rate of 7.03% (95% CI 5.83%–8.23%) per annum, Africa will have 3418 (95% CI 1811–6080) neurosurgeons by 2030, with a deficit of 5191 neurosurgeons, based on population workforce targets. In terms of training, there are 106 neurosurgery training institutions in 26 African countries. North Africa has 52 training centers (49.05%), West Africa 23 (21.70%), East Africa 15 (14.15%), Southern Africa 14 (13.21%), and Central Africa 2 (1.89%). The major regional training programs are those of the West African College of Surgeons (24 sites in 7 countries) and the College of Surgeons of East, Central, and Southern Africa (17 sites in 8 countries). CONCLUSIONS The study is limited as it is based on the online literature, some of which includes modeled estimates with questionable reliability. However, the results indicate that while countries in North Africa are expected to surpass their population workforce requirements, sub-Saharan African countries are likely to have significant workforce deficits accentuated by the paucity of neurosurgery training programs. To meet the 2030 population workforce requirements, the continent’s exponential growth rate should be scaled up to 15.87% per annum. Scaling up neurosurgical training would help to meet this target and requires collaborative efforts from continental, regional, and national agencies and international organizations.
SUMMARY:The anti-inflammatory effect of dexamethasone on the irradiated kidneys of adult Wistar rats (Rattus norvegicus) was studied. Eighteen adult Wistar rats were, after acclimatization, randomly divided into 3 groups of 6 animals per group. The control group had normal saline, receiving neither drugs nor radiation. The second group received normal saline and radiation. The third group received pretreatment with dexamethasone at 1mg/kg body weight/day for 2 days followed by radiation. Radiation was delivered to the animals as a single fraction of 2.5 Gy of gamma rays from Cobalt-60 source, using an AECL Theatron 780-C Teletherapy machine. After exposure to the different interventions, the animals were sacrificed on the 14 th post-irradiation day and the kidneys dissected out from each animal. The renal tissues were subjected to histological processing, and then studied using an eyepiece objective ruler calibrated with a 2mm stage micrometer for histomorphometric studies. The result of the study showed that all irradiated animals suffered weight loss by the 14 th day post-irradiation (p<0.05) irrespective of the additional treatment with dexamethasone and this was statistically significant. Histomorphometry showed that the maximum width of the glomerular capsule was significantly greater in the radiation groups than in the control at p<0.05. The maximal glomerular diameter was significantly greater in irradiated animals compared with the control animals at p<0.05. The outcome of this study showed that the intraperitoneal administration of dexamethasone at 1mg/kg body weight/day for 2 days prior to treatment with irradiation did not prevent weight loss nor ameliorate the swelling of the nephrons resulting from the effect of radiation injury to the Wistar rat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
