Predatory journals (PJs) publish research with little to no rigorous peer review in exchange for money. It is unclear what proportion of researchers is vulnerable to PJs and which factors are associated with vulnerability. The aim of this study was to evaluate the vulnerability of African neurosurgery researchers to PJs and identify their correlates.A 3-part electronic survey in English and French versions was distributed via social media to African consultants and trainees from November 1 to December 1, 2021. Bivariable relationships were evaluated with χThere were 101 respondents to the survey (response rate 56.1%). Respondents had mean age of 34.9 years, 82.2% were male (n = 83), 38.6% were consultant neurosurgeons (n = 39), and 33.7% were from Central Africa (n = 34). Of respondents, 66 had published ≥ 1 articles in the past, and 13 had published at least 1 article in a PJ. A PJ had contacted 34 respondents via e-mail, and 8 respondents had reviewed articles for a PJ. The Think. Check. Submit initiative and Beall's list were familiar to 19 and 13 respondents, respectively. Publication in PJs was correlated with the respondent's age (R = 0.23, P = 0.02) and total scholarly output (R = 0.38, P0.01).Young African neurosurgery researchers are vulnerable to PJs primarily because they are not familiar with the concept of PJs or how to identify them.

Introduction: Gliomas are tumors of the supporting cells of the central nervous system. They have great heterogeneity in their clinical and pathological features as well as prognosis. There is paucity of glioma epidemiology data in Zimbabwe. We carried out a study to determine the landscape, presentation, and characteristics of brain gliomas in Zimbabwe. Materials and Methods: A prospective cross-sectional study was conducted in Zimbabwe over a 2 years period to determine descriptive epidemiological data with regards to demographic distribution, presentation, and tumor characteristics. Consecutive patients from across the country with brain gliomas were recruited in the study. Results: A total of 112 brain tumors were diagnosed histologically. Of these 43.8% (n = 49) were gliomas and hence recruited in the study. The mean age of study participants was 40.3 years (standard deviation = 23.1 years), range 3–83 years. Male to female ratio (M:F) was 1:1. The study population consisted of 14% caucasians (n = 7), 83.7% black (n = 41), and 2% (n = 1) were of mixed race. Eighty-six percent (n = 42) of participants were from urban areas. The most common presenting complaint was headache in 87.8% (n = 43). The majority (61.2%) presented with a Karnofsky score ≥70%. Astrocytomas were the most common gliomas constituting 57.1% (n = 28), followed by ependymomas and oligodendrogliomas being 8.1% (n = 4) each. There was no statistical difference in the hemisphere of the brain involved (P = 0.475). Eight percent of the population were HIV positive (n = 4). Age above 60 years has an adjusted odds ratio of 13 for presenting with high-grade tumors. Conclusion: There is a disproportionately high number of gliomas among Caucasians, urban dwellers, and those gainfully employed. The prevalence of HIV in glioma patients is less than that of the general population.

Background. Traumatic brain injury (TBI) imposes an enormous burden on health systems and it is the most frequent cause of hospitalization in children. This study aimed at describing the causes, presentation, management, and outcome of children with TBI admitted at a tertiary referral hospital in Harare, Zimbabwe. Methods. This prospective cohort study was conducted with a convenience sample of children aged ≤ 12 years and admitted with TBI at the study site from June 2018 to May 2019. The children were followed from their admission to one-month post-discharge. Sociodemographic, clinical, and neuroimaging data were collected. The median length of stay was calculated and the Chi-square, Fisher’s exact, and Kruskal Wallis tests were used. Results. 84 children with TBI were recruited. Most were males (66.7%) and (56.0%) had sustained TBI following a motor vehicle accident. An initial period of loss of consciousness that lasted a median of 6.5 (IQR = 4.8) hours was noted in 60.7% of patients. The most common symptom at presentation was headache (61.9%), and mild TBI was the most common type of TBI. Skeletal injuries were the most encountered associated injuries (13.1%) and the majority of patients were managed non-operatively – 79 (94.0%). Most patients (56.0%) experienced upper good recovery at one-month follow-up. Conclusions. Motor vehicle accidents are the main cause of pediatric TBI in Zimbabwe. Most patients do not require surgical treatment and have a good recovery.

Introduction: Microsurgical clipping and Endovascular coiling (EC) are both effective alternatives in the management of intracranial aneurysms. EC has been shown to be associated with the risk of recurrent aneurysm (RA) growth. Considering the minimally invasive nature of this procedure, the management of intracranial aneurysms has been skewed toward EC, especially in the developed world. In this scenario, there has been an upsurge of RAs after EC. Since the optimal management of these RAs has not been defined, they pose a unique challenge to the treating surgeons. Aims and Objectives: The aim of this study is to elucidate the optimal management of RAs after EC. Materials and Methods: Medical records of all patients who underwent surgery for RAs were reviewed from the period January 2014 to March 2019. The demographic and angiographic patterns of the patients and operative techniques and complications were studied. The outcome was dichotomized into good and bad depending on the Glasgow outcome scale (GOS). Results: There were four cases of RAs operated in our institution between the above-mentioned period. There were varied differences between the initial coiling and time to recurrences. All four patients were operated under neuromonitoring. Three underwent clipping and one patient underwent clipping with bypass. All four patients had good outcome with a GOS of 5/5. Conclusion: Operations for RAs constitute many technical challenges and require a lot of expertise. Such surgeries are recommended in high-volume centers, with sufficient experience in both clipping and cerebral bypass.

Basilar apex aneurysms constitute 5%–8% of all intracranial aneurysms. Microsurgical clipping of basilar tip aneurysms is still advocated for as it is safe, especially for unruptured basilar tip aneurysms which have a low risk of postoperative mortality or morbidity. Careful patient preparation is needed preoperatively because the risk of intraoperative rupture is significant. Good surgical techniques should be applied. The skill will need to be preserved as endovascular surgery becomes more popular.This is a case of basilar tip aneurysm managed by clipping through the anterior temporal approach, followed by a review of the literature.

The recurrence of aneurysms postcoil embolization is a common occurrence. Endovascular coiling has been noted to be more effective for small lesions rather than the giant aneurysms. A postembolization recurrent aneurysm is a difficult condition to manage. We present a case of a recurrent giant aneurysm of the anterior cerebral arteries (ACAs) first segment (A1). It was managed by superficial temporal artery to A3 segment of anterior cerebral artery bypass anastomotic revascularization plus distal A1- segment clipping. A literature review is presented for the management of giant A1 artery aneurysms.

Introduction COVID-19 has affected the global provision of neurosurgical services. We sought to review the impact of COVID-19 on the neurosurgical services in Africa. Methods A cross-sectional survey was distributed to African neurosurgeons seeking to review demographics, national and neurosurgical preparedness, and change in clinical services in April 2020. Results A total of 316 responses from 42 countries were received. Of these, 81.6% of respondents were male and 79.11% were under the age of 45 years. In our sample, 123 (38.92%) respondents were in training. Most (94.3%) respondents stated they had COVID-19 cases reported in their country as of April 2020. Only 31 (41.50%) had received training on managing COVID-19. A total of 173 (54.70%) respondents were not performing elective surgery. There was a deficit in the provision of personal protective equipment (PPE): surgical masks (90.80%), gloves (84.80%), N95 masks (50.80%), and shoe covers (49.10%). Health ministry (80.40%), World Health Organization (74.50%), and journal papers (41.40%) were the most common sources of information on COVID-19. A total of 43.60% had a neurosurgeon in the COVID-19 preparedness team; 59.8% were concerned they may contract COVID-19 at work with a further 25.90% worried they may infect their family. Mental stress as a result of COVID-19 was reported by 14.20% of respondents. As of April 2020, 73.40% had no change in their income. Conclusions Most African countries have a national COVID-19 policy response plan that is not always fully suited to the local neurosurgery services. There is an ongoing need for PPE and training for COVID-19 preparedness. There has been a reduction in clinical activities both in clinic and surgeries undertaken.

Background Containment measures for COVID-19 have affected surgical training globally. We sought to assess how neurosurgical training has been affected across Africa in April 2020. Methods A cross-sectional survey was distributed to African Neurosurgical trainees seeking to review demographics and effects of COVID on training. Results A total of 123 neurosurgery trainees responded from 23 African countries and a further 6 were abroad. A total of 91.80% were men, and 96.70% were training in public institutions. Only 41% had received training in COVID-19 with 61.79% worried that they would contract COVID-19 while performing their clinical duties. There was a marked reduction in clinical activities including a median reduction of elective surgery (−80%), clinics (−83%), and emergency surgery (−38.50%). A total of 23.58% of residents did not receive a formal salary, with 50% on less than $1000 USD gross per month. Conclusions This is the first continental survey of neurosurgery trainees in Africa. COVID-19 has significantly affected clinical and learning opportunities. There are concerns of the long-term effects on their training activities for an uncertain period of time during this pandemic. Although there has been a global increase in e-learning, there is need to evaluate if this is accessible to all trainees.

Shunting for hydrocephalus can lead to improvement in the quality of life although the latter has been subdued by complications like shunt infection. Established protocols have contributed to the reduction of ventriculoperitoneal shunt (VPS) infections. Previously, we retrospectively demonstrated a low infection rate despite some of the protocol recommendations not being implemented. The aim of this study was to prospectively establish the incidence of shunt infection in the early post-shunt period following our protocol and elucidate on associated risk factors. A multicenter prospective descriptive cohort study of consecutive 209 under-5 children requiring VPS for hydrocephalus was conducted between January 2013 and November 2018. An innovative protocol insisting on intermittent application of povidone-iodine on the skin during the operation was implemented. The patients were followed-up for 3 months post-surgery. Included were 211 VPS procedures performed on 209 children. The median age was 9 months and 84 were males. Hydrocephalus was non-communicative in 72.0% and aqueductal stenosis was its most frequent cause (84.9%). Most surgeries were performed in the morning (90.5%), electively (95.3%), and for the first time (91%). The median duration of surgery was 65 min. Shunt infection rate was 1.9% (n = 4) (95% CI 0.7 to 5.0%) per procedure. The observed infection rate was low. This suggests that the protocol followed captured the most critical components necessary to ensure low infection rates and that simple measures implemented in economically challenged environments may achieve internationally acceptable infection rates.

Background The management of cavernous carotid aneurysms (CCAs) poses a significant dilemma to the treating surgeon. Asymptomatic CCAs usually are managed conservatively with clinical and radiologic follow-up. Large size, intradural extension, sphenoid bone erosion, and increasing size on follow-up are usual indications for treating asymptomatic CCAs. However, there are no clear-cut guidelines in literature. We share our experience of 40 asymptomatic CCAs treated by endovascular and surgical methods. Methods All the asymptomatic CCAs treated between January 2014 and December 2018 were analyzed retrospectively. Patient demographics, aneurysm characteristics, postprocedural complications, and clinical and radiologic follow-up data were obtained from records. Outcome was evaluated in terms of aneurysm obliteration and maintained cerebral perfusion, postoperative complications, recurrence, and clinically significant complications during follow-up. Results Endovascular coiling, balloon-assisted coiling, and stent-assisted coiling were performed in 27 (75%), 5 (13.9%), and 4 (11.1%), respectively. Raymond–Roy occlusion classification grade I occlusion was achieved in 88.9% of cases. No immediate or delayed complications were noted. Coil compaction was seen in 4 (11.1%) patients. In the surgery group, all patient underwent high-flow bypass with radial artery graft. Aneurysm exclusion with good graft patency was achieved in all 4 cases without any permanent morbidity or mortality. Conclusions The current study demonstrates excellent outcomes of asymptomatic CCAs after treatment. In view of the technical advancements of both surgical and endovascular methods, consideration for treatment should be given to asymptomatic CCAs. Each aneurysm should be individually assessed by experts for choosing the best endovascular or surgical treatment option.

Pleomorphic xanthoastrocytoma (PXA) is a rare cerebral tumor, accounting for

Bobble-head doll syndrome is a rare movement disorder that is usually associated with lesions involving the third ventricle. It is characterised by stereotypical rhythmic up-and-down or side-to-side head movements. The pathophysiology and anatomical basis for this unusual manifestation is still a subject of intense scrutiny. The syndrome has never been described in a patient with both hydranencephaly and Chiari type 3 malformation. We describe a 2-year-old female patient who presented with congenital hydrocephalus, an occipital encephalocele and rhythmic bobbling of the head. Imaging investigation revealed a Chiari type 3 malformation and hydranencephaly. The patient was taken to theatre for a ventriculoperitoneal shunt insertion, and at day 3 post operatively, the patient had a markedly decreased head circumference and a decrease in the frequency of the bobbling of the head. A further review at 2 weeks showed that the bobbling of the head had ceased. Although the pathophysiology of bobble-head doll syndrome is yet to be fully understood, there has been postulation of either a third ventricular enlargement or a cerebellar dysfunction to explain bobble-head doll syndrome. Our case illustrates that the pathophysiology is most likely multifactorial as illustrated by the fact that by just addressing the high intracranial pressure with a shunt was sufficient to treat the condition.

It is exceptionally rare to have posterior atlanto axial dislocation without an associated atlas or odontoid fracture and very few cases have been reported in literature. We present a case of a 50 year old female pedestrian who was hit by car while crossing a road. She presented with a depressed level of consciousness and the Glasgow coma score of 12/15, pupils were equal and reactive to light and all limbs were moving equally. She had an extensive abrasion on the forehead which extended into scalp. CT scan showed a posterior dislocation of the atlas with respect of axis with no associated fractures of C 1 and C2. She had traumatic subarachnoid hemorrhage in the basal cisterns and multiple brainstem contusions. Closed reduction of the dislocation was done successfully under fluoroscopy guidance. MRI was done post reduction because funds were not available initially and it showed increased signal in the tectorial membrane and transverse and alar ligaments with mild cord oedema at the cervicomedullary junction. However, the patient post reduction began to deteriorate and eventually passed away before definitive treatment of her cervical-spine injury. The case is reported in view of its rarity and to review literature on this uncommon condition.

Phenytoin toxicity masquerading as deterioration of neurological symptoms caused by interaction with chloramphenicol is a very rare but real risk. To the authors’ knowledge only one such case occurring in humans has been reported in the English literature. No case of clinical phenytoin toxicity occurring at less than double the serum phenytoin therapeutic levels, occurring as a result of chlorampenicol interaction has been documented, hence our report. A 17 year old man, whose frontal subdural empyema had been drained, had his seizures well controlled on phenytoin. Shortly after, he had a parasagital subdural empyema which was also drained. He was put on chloramphenicol. He improved tremendously until he then developed cerebellar symptoms. Phenytoin levels were noted to be almost twice the maximum therapeutic value. On stopping chloramphenicol, phenytoin levels normalized and symptoms resolved. Possibility of phenytoin toxicity should always be entertained in patients who are also taking chlorampenicol, presenting with new or worsening neurological symptoms.

Cardiovascular disease is a leading cause of mortality in all ages worldwide. Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD) accounting for 10%. There have been several reports of neurological complications associated with TOF. Although it is known, brain abscess (BA) is a serious complication in patients with uncorrected CHD mostly in the age of 4-7 years-old. We report a case of a 7 year old male who presented with a 3 month history of left sided body weakness and a 3 week history of a headache and fever. Patient was chronically unwell since birth where he would experience occasional episodes of exertional dyspnoea which was never investigated. Chest xray showed a globular-shaped heart. CT scan brain showed a 1,8 x 1,3 x 1,5 cm ring-enhancing lesion in the right parietal region with minimal perilesional vasogenic edema communicating with the body of the lateral ventricle, with enhancement of the ependymal lining of the ventricle; echocardiography revealed ventricular septal defect (VSD), overriding of aorta, obstruction to right ventricular outflow tract and hypertrophy of right ventricle consistent with a diagnosis of TOF. We elected to manage the patient conservatively on intravenous antibiotics, Patient improved significantly neurologically and was transferred to the cardiothoracic surgeons for further management of TOF.

Background Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is associated with an increased prevalence of some malignancies. However, some observational studies have revealed an ever-decreasing prevalence of HIV in glioma patients. The relationship between HIV and brain gliomas has not been well established. Methods A cross-sectional study was carried out in sub-Sahara Africa, a high HIV prevalence setting, to determine the prevalence of HIV among all glioma patients over a 2-year period. Results A markedly reduced prevalence of HIV was found in glioma patients (8.3%) in comparison to the general population (14.3%). The presumably "antiglioma effect" of HIV and/or its treatment resulted in a 42% decrease in glioma occurrence in HIV positive patients compared to HIV negative individuals. Age and sex-adjusted prevalence were also lower among glioma patients with the protective effect observed more in younger patients and female sex. Conclusion Our results corroborate the protective effect of HIV positivity vis-a -vis gliomas. This "antiglioma effect" could be attributed to either the HIV, its treatment, or both. Future studies focused on this "effect" may help unveil better preventative and possible therapeutic avenues for gliomas.

A subdural hematoma (SDH) is usually traumatic in etiology. Non-traumatic instances of SDH are uncommon, and are rarely due to metastases involving the dura. We report a 68-year-old male patient with a one day history of, not communicating and not mobilizing and a 2 weeks history of generalized body weakness. A computed tomography (CT) scan revealed a left sided hypo-dense subdural collection. A diagnosis of left sided chronic subdural hematoma (SDH) was made. Burr hole drainage of the hematoma was performed. Intra- operatively, liquefied blood was drained and a thick dura with reddish material infiltrating the dura was noted. A specimen of the dura was submitted for histology and revealed metastatic carcinoma, confirmed at immunohistochemistry to be of prostatic origin. Conclusion: Metastatic disease should be considered when there is a chronic subdural hematoma with no history of trauma and an unusual dural appearance on imaging.

Neurofibromatosis type 1 (NF1) is an autosomal dominant condition affecting approximately 1 in 3000 live births. The manifestations of this condition are extremely variable, even within families, and genetic counseling is consequently difficult with regard to prognosis. Individuals with NF1 are acknowledged to be at increased risk of malignancy. Several studies have previously attempted to quantify this risk, but have involved relatively small study populations. Soft tissue tumors represent a heterogeneous group of mesenchymal and neural lesions. We report a case of giant scalp Fibrosarcoma of the scalp in patient with neurofibromatosis type I without intracranial extension, in a 35 year old female which was excised completely along with the involved overlying skin, and reconstruction was done to cover the defect using trapezius flap and split thickness skin graft from the right thigh. She is doing well after treatment and is in regular follow up while awaiting further management by the oncologists.

Hydranencephaly is a rare condition characterised by complete or near complete absence of the cerebral hemispheres within relatively normal sized meninges and skull, the resulting cavity being filled with cerebrospinal fluid. The following is a case report of a five month old hydranencephalic child with right upper motor facial nerve palsy who presented with signs of hydrocephalus who developed intractable hypothermia rapidly post ventriculo-peritoneal shunt insertion and demised. Her preoperative condition was associated with hypothermia.
