Paediatric Renal Stone Management in Africa: A Scoping Review and Analysis of Current Practices.

Renal stones are solid deposits formed from minerals and salts that develop within the kidneys and urinary tract. While the condition is more common among adults, children and even infants can also be affected. There is an increasing incidence of paediatric renal stones in Africa alongside multiple challenges faced in managing the condition. This scoping review aimed to provide an overview of the management modalities of paediatric renal stones in Africa. This study utilised Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. A systematic search was conducted in three electronic databases: PubMed, African Journal Online (AJOL), and Google Scholar, with 1,180 articles curated. After extensive examination, 10 articles satisfied the inclusion criteria. The review found that calcium oxalate stones were the most prevalent type, accounting for 34.03% of cases, followed by whewellite stones and ammonium urate stones. The most frequent location for stones was the kidney, and the most common symptom was pain. Abdominopelvic ultrasound was the most frequently utilised investigation. Of the 886 patients managed for renal stones, 75.4% were managed surgically, 2.9% medically, and 21.7% spontaneously resolved without intervention. This review identifies opportunities for improving the management of paediatric renal stones in Africa, including the need for standardised diagnostic and treatment protocols and the development of evidence-based guidelines tailored to the African context. Overall, this scoping review provides valuable insights into the patterns and management of paediatric renal stones in Africa and highlights the need for further research to improve the management of this condition in the region.

Burden of Traumatic Spinal Cord Injury in Sub-Saharan Africa: A Scoping Review.

INTRODUCTION: With a varying annual incidence across populations, traumatic spinal cord injury (TSCI) remains a public health concern of utmost importance, especially in developing countries with an incidence rate ranging from 12.7 to 29.7 per million people and a postulated increase in the number of patients living with undesirable complications of this condition. It is against this background that we reviewed the literature to bring to light the epidemiology, burden, management, and outcomes of TSCIs across Africa. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used in this study. We included descriptive studies with data on the incidence, presentation, management, and outcomes of TSCIs in African surgical centers. We conducted our search on PubMed and OVID Embase and supplemented it with an extensive review of African Journal Online and Google Scholar. RESULTS: Thirteen papers were identified from our search. Most papers were from Nigeria (n = 4) and Tanzania (n = 3). In total, our review included 1332 persons across the different centers. There were more males than females (n = 1029/1332, 72%). The most common etiology was road traffic accidents, constituting 44%, while falls and other mechanisms like assault and sports injuries had 28% each. The incidence of TSCI varied from 13 per million population per year in Botswana to 75.6 per million population per year in South Africa. CONCLUSIONS: The incidence of the traumatic condition in certain parts of Africa is significantly higher than in other parts of the world, suggesting the need for an urgent call to action regarding addressing its key drivers.

Gastroschisis in Sub-Saharan Africa: a scoping review of the prevalence, management practices, and associated outcomes.

Gastroschisis is a congenital defect of the anterior abdominal wall characterized by a periumbilical abdominal wall defect with associated bowel protrusion. Limitations in the diagnosis and management of gastroschisis in Sub-Saharan African countries contribute to the high mortality rate. Few studies have been published despite its significant contribution to neonatal mortality in Sub-Saharan Africa. This review study explores the prevalence of gastroschisis, likewise the management and clinical outcomes. Full-text articles reporting the prevalence, management, and associated outcomes of gastroschisis in Sub-Saharan Africa were included. Data were extracted from databases such as PubMed, Google Scholar, and Ajol following a systematic search. The study was reported following the PRISMA-ScR guideline. A total of ten articles which included studies conducted from 1999 to 2022 fulfilled the criteria. The prevalence of gastroschisis varied widely, ranging from 0.026 to 1.75 with an overall mortality rate of 62.48%. Young maternal age is strongly associated with the incidence of gastroschisis. The study showed a slight male preponderance with a M: F ratio of 1.12:1. Staged closure with silos is the preferred method of management, it is explicitly linked to improved clinical outcomes. The prevalence rate and associated mortality of gastroschisis remain alarmingly high in most of the studies. There is a need for advanced diagnostic and management practices as well as increased awareness of gastroschisis to reduce mortality and improve survival outcomes.

A Scoping Review of Kidney Transplantation in Africa: How Far have We Come?

INTRODUCTION: Kidney transplantation is a life-saving treatment for end-stage kidney disease (ESKD) patients. However, access to this treatment in Africa lags behind other regions, leading to significant disparities in care. We aimed to analyse the indications, demographics, and outcomes of kidney transplantation in Africa. METHOD: We conducted a systematic review of studies from PubMed, Google Scholar, and African Journal Online using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We pooled and analysed data on procedure type, graft outcomes, donor type, prophylaxis, post-operative complications, and survival from 33 eligible studies. RESULT: The most common causes of ESKD requiring transplantation were glomerulonephritis and nephroangiosclerosis. Open nephrectomy was the predominant surgical approach (95%). Living donors accounted for 56.3% (4221) of all donors, with 68.5% being related to the recipient. Cadaveric donors accounted for 43.7% (3280) of transplants. Graft rejection was the most common surgical complication (39.44%), and 60.49% of patients developed hypertension in the follow-up period. CONCLUSION: Our study highlights the potential of kidney transplantation to improve the lives of ESKD patients in Africa. However, further research and infrastructure development are necessary to make this treatment more widespread and successful.

Factors associated with post traumatic hydrocephalus following decompressive craniectomy: A single-center experience.

Background: A decompressive craniectomy (DC) is a surgical procedure sometimes utilized to manage refractory intracranial hypertension following severe traumatic brain injury (sTBI). The previous studies have established a relationship between DC and post traumatic hydrocephalus (PTH). This study aimed to identify the factors responsible for developing shunt-amenable PTH in patients who underwent DC following sTBI. Methods: A review of a prospectively collected database of all patients admitted with severe TBI in a tertiary neurosurgical center in North-west England between January 2012 and May 2022 was performed. PTH was defined as evidence of progressive ventricular dilatation, clinical deterioration, and/or the eventual need for cerebrospinal fluid diversion (i.e., a ventriculoperitoneal shunt). Statistical analysis was carried out using IBM SPSS versus 28.0.1. Results: Sixty-five patients met the eligibility criteria and were included in the study. The mean age of the PTH group was 31.38 ± 14.67, while the mean age of the non-PTH group was slightly higher at 39.96 ± 14.85. No statistically significant difference was observed between the two groups' mechanisms of traumatic injury (P = 0.945). Of the predictors investigated, cerebellar hematoma (and contusions) was significantly associated with PTH (P = 0.006). Conclusion: This study concludes that cerebellar hematoma (and contusions) are associated with developing PTH in patients undergoing DC.

Decompressive Craniectomy and Shunt-Amenable Post-Traumatic Hydrocephalus: A Single-Center Experience.

Background: Prior studies have shown that decompressive craniectomy may be an independent risk factor for the development of post-traumatic hydrocephalus (PTH). It is upon this background that we chose to conduct our single-center retrospective study to establish the possibility of an association between decompressive craniectomy and PTH. Methods: A retrospective review involving a database of all patients with traumatic brain injury was undertaken. All referrals and admissions with traumatic brain injury, as defined by the Mayo Classification, from January 2012 to May 2022, were included in the subsequent analysis. Statistical analysis was carried out using IBM SPSS version 28.0.1. Results: The mean age of the cohort was 44.91 ± 19.16 with more males (82.3%) than females (17.7%). Vehicle incident/collision was the most common cause of traumatic brain injury. 84% of the cohort was alive at 30 days, 4% were noted to have an intracranial infection, and 3% underwent shunt insertion procedures, while 14% received decompressive craniotomies as part of their clinical management. There was a statistically significant association between undergoing decompressive craniectomy, and the development of PTH (odds ratio, 4.759 [95% confidence interval, 1.290-17.559]; P = 0.019). The presence of intracranial infection and insertion of an external ventricular drain insertion were also independent predictors of developing PTH. Conclusions: This study adds to the growing body of work regarding the immediate and long-term effects of the procedure. Although life-saving, PTH, needing shunt insertion, is one of the possible complications that surgeons and patients should be aware of.

A Scoping Review of the Management of Benign Prostate Hyperplasia in Africa.

Benign prostatic hyperplasia (BPH) is a non-malignant prostate gland enlargement of unknown cause that affects more than 50% of men over 60 and is the most common cause of bladder outlet obstruction and voiding symptoms. BPH is treated primarily with watchful waiting, phytotherapy (herbs), and medical or surgical options. In this study, we sought to examine the different management practices in African urological centers, outcomes of management, and complications. A literature search was conducted using PubMed, African Journal Online, and Google Scholar regarding the management of BPH from inception till date. Articles were selected based on their relevance to the management of benign prostatic enlargement in Africa. Results are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. The studies included were conducted from 1997 to 2022. They were from eight different African countries (Nigeria, Kenya, Togo, Ethiopia, Egypt, South Africa, Ghana, and Congo), with Nigeria contributing the most with 10 studies. Exactly 2999 patients were included in the study. Seventy-three (73.49%) percent of these patients totaling 2204, underwent surgical management of BPH, 124 (4.13%) patients were treated with phytomedicines or herbs, and 684 (22.80%) patients were treated with medical therapy. The complications and outcomes were studied and collated. A total of 808 patients opted for non-surgical treatment for BPH in the included studies. In this group, 124 were treated using phytochemicals or natural herbs, and 648 were treated with standard prescription medications. While surgical treatment for benign prostatic enlargement is shifting towards minimally invasive procedures in the developed world, open prostatectomy is still quite popular in Africa. Further research should focus not only on the reason for these disparities in management but also on the rationale for the selection of medical, surgical, or phytotherapy in African urological centres.

Endoscopic third ventriculostomy versus ventriculoperitoneal shunt insertion for the management of pediatric hydrocephalus in African centers - A systematic review and meta-analysis.

Background: Ventriculoperitoneal shunt (VPS) insertion and endoscopic third ventriculostomy (ETV) are common surgical procedures used to treat pediatric hydrocephalus. There have been numerous studies comparing ETV and VPS, but none from an African perspective. In this study, we sought to compare outcomes from African neurosurgical centers and review the associated complications. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used in conducting this study. PubMed, Google Scholar, and African Journal Online were searched. Data on treatment successes and failures for ETV and VPS were pooled together and analyzed with a binary meta-analysis. A clinically successful outcome was defined as no significant event or complication occurring after surgery and during follow-up (e.g., infection, failure, CSF leak, malfunction, and mortality). Seven studies fully satisfied the eligibility criteria and were used in this review. Results: There was no statistically significant difference between the outcomes of ETV and VPS (OR- 0.27; 95% CI -0.39-0.94, P = 0.42). After reviewing the rates of complications of ETV and VPS from the identified studies, four were recurrent. The infection rates of ETV versus VPS were 0.02% versus 0.1%. The mortality rates were 0.01% versus 0.05%. The reoperation rates were 0.05% versus 0.3%, while the rates of ETV failure and shunt malfunction were 0.2% versus 0.2%. Conclusion: This study concludes that there is no significant difference between the outcomes of ETV and VPS insertion.

A Scoping Review of the Use of Improvised External Ventricular Drains in Africa.

Poor access to neurosurgical equipment is one of the problems limiting service delivery in Africa. Improvised surgical devices have long been used in Africa as replacements for high-cost standard versions. In this study, we aimed to see if improvised external ventricular drains (EVD) are being used, how these devices are made, and what their outcomes are. The PRISMA extension for scoping reviews was used in conducting this study. A search was conducted from inception to July 2022. PubMed, Ovid Embase, and African Journal Online were searched. Three studies were identified and used. The methods of making the EVD devices were compared and the incidence proportions of improvised EVD-related infections were calculated. The standard ventricular catheter was replaced by cheaper alternatives like a size 6/8 feeding tube or a 14-gauge central line catheter. The connecting tube had low-cost alternatives, and in a study, was replaced by a fluid infusion set. Aggregated outcomes from the three identified studies show that just over half of the sample survived post-EVD insertion (54%). The incidence proportion of EVD-related infections was 24%. This study describes the experience of African centers with an improvised version of the EVD devices and their outcomes. This will serve as a baseline for more research into the use of improvised EVD devices in low-resource settings.
