World Neurosurg 2024; 189:e498-e518. [PMID: 38914134 DOI: 10.1016/j.wneu.2024.06.103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 06/17/2024] [Accepted: 06/18/2024] [Indexed: 06/26/2024]
Abstract
BACKGROUND Pediatric hydrocephalus is a significant health burden globally, particularly in low- and middle-income countries. Data from specific regions such as KwaZulu-Natal, South Africa, are lacking. This study aimed to investigate pediatric hydrocephalus by comparing 4 distinct 5-year periods. METHODS Data were collected retrospectively (2003-2007, 2008-2012, and 2013-2017) and prospectively (2018-2022). Children (≤18 years old) treated for hydrocephalus were included. Data on demographics, referral patterns, etiology, treatment modalities, and outcomes were collected and analyzed. RESULTS A total of 3325 children were treated. The peak period was 2008-2012 (35.3%). Most children (51.4%) were from rural areas (P = 0.013), and 47.9% were referred from regional hospitals (P < 0.001). Boys (56.4%) and infants (60.2%) were predominant groups (P < 0.001). Postinfectious etiology (32.7%) was predominant (P < 0.001), particularly tuberculous meningitis (54.1%). Ventriculoperitoneal shunts were the mainstay treatment (84.2%), with notable complication rates (20.4%), including infections (9.6%). Human immunodeficiency virus co-infection was diagnosed in 2.5% of cases. Weekend procedures were associated with ventriculoperitoneal shunt complications (hazard ratio [HR] = 1.3, 95% confidence [CI]1.03-1.66, P = 0.03). Mortality rate was 7.9%, and age ≥1 year (HR = 2.43, 95% CI 1.87-3.17, P < 0.001), tertiary hospital referral (HR = 1.48, 95% CI 1.06-2.04, P = 0.019), ventriculoperitoneal shunt infection (HR = 3.63, 95% CI 2.66-4.95, P < 0.001), acute abdomen (HR = 2.17, 95% CI 1.11-4.25, P = 0.024), and pneumonia (HR = 7.32, odds ratio = 4.84-11.06, P < 0.001) were associated with mortality. CONCLUSIONS This study provides comprehensive insights into pediatric hydrocephalus in KwaZulu-Natal. Monitoring temporal trends and predictors of outcomes will guide future interventions to mitigate the burden of pediatric hydrocephalus in the region.

Abstract
INTRODUCTION Ventriculoperitoneal shunt (VP shunt) insertion is one of the mainstays of treatment of hydrocephalus and although very effective, a high rate of shunt failure persists globally. The purpose of the study was to quantify the ventriculoperitoneal shunt failure rate at Red Cross War Memorial Children's Hospital (RCWMCH) and assess potential factors contributing to shunt failures. METHODS A retrospective review of VP shunts done at RCWMCH between August 2015 through December 2019 was performed. Operative notes, discharge summaries and patient folders were reviewed to collect information about patient age, aetiology of hydrocephalus, index vs revision shunt, shunt system and other noticeable variables. Overall shunt failure was recorded. Univariate and multivariate models were used to determine causal relationship. RESULTS Four hundred and ninety-four VP shunt operations were performed on 340 patients with 48.8% being index shunts and 51.2% revision shunts. The average patient age was 3.4 months. The total VP shunt failure rate over the study period was 31.2%, with a 7.3% infection rate, 13.6% blockage and 3.6% disconnection rate. The most common aetiologies were post-infectious hydrocephalus 29.4%, myelomeningocele 19.7% and premature intraventricular haemorrhage 14.1%. Orbis-sigma II (OSVII), distal slit valves and antibiotic-impregnated catheters were used most frequently. Failure rates were highest in the revision group, 34.7% compared to 27.3% in index shunts. Sixty-five percent (65%) of the head circumferences measured were above the + 3 Z score (> 90th centile). CONCLUSION VP shunt failure occurs most commonly in revision surgery, and care should be taken at the index operation to reduce failure risk. Surgeon level, duration of surgery, aetiology of hydrocephalus and shunt system used did not influence overall failure rates. A closer look at larger head circumferences, their effect on shunt systems and the socio-economic factors behind late presentations should be investigated further in the future.

Ventricular Anatomical Differences-A Different Perspective on Endoscopic Treatment of Pediatric Hydrocephalus: Anomalies, Variations, and Deformations. World Neurosurg 2024:S1878-8750(24)01437-2. [PMID: 39153570 DOI: 10.1016/j.wneu.2024.08.068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2024] [Accepted: 08/12/2024] [Indexed: 08/19/2024]
Abstract
OBJECTIVE Endoscopic management of pediatric hydrocephalus is always challenging because of the different anatomical structure of the ventricles. The aim of this study is to document the endoscopic anatomy of the ventricular system and to show the variations and deformations. METHODS The study included 84 children who underwent endoscopic surgery for the treatment of hydrocephalus in the department of neurosurgery between 2017 and 2022. All preoperative and postoperative radiological images and intraoperative video recordings were retrospectively analyzed. Anatomy of the lateral ventricles and the third ventricle, variations, and deformations were detected and evaluated in detail. RESULTS The mean age of the patients was 7.6 months. Myelomeningocele-encephalocele-associated hydrocephalus was the most common cause of hydrocephalus (38%), followed by postventriculitis in 21%, posthemorrhagic in 21%, and obstructive causes in 20% of cases, respectively. Endoscopic anomaly/variation or deformation was detected in 83% of all cases. Based on the preoperative radiological images, septum pellucidum anomaly/variation or deformation was the most common radiological finding in 64% of the cases. Lateral ventricle anomaly/variation or deformation was noted in 62% of the cases, and third ventricle anomaly/variation or deformation was observed as a radiological finding in 27% of the cases. CONCLUSIONS The compliance of the brain deteriorates with increasing intracranial pressure in pediatric hydrocephalus and the intraventricular anatomical structures differ from the normal anatomy. Developmental anomalies of the ventricle are also significant and since all these variations are often unpredictable on preoperative imaging, awareness of endoscopic anatomy, variations, and deformations will improve operative safety in children.

Abstract
BACKGROUND Raising a child with hydrocephalus can be very challenging, especially in low- and middle-income countries. In Pakistan, mothers being the primary caregivers for their hydrocephalic children are under tremendous stress. METHODS This study explores the challenges faced by Pakistani mothers raising children with hydrocephalus, employing a qualitative methodology through focus group discussions comprising ten mothers of hydrocephalic babies at Tertiary Care Hospital in Pakistan. RESULTS The findings highlight three main themes: emotional toll, social isolation, and financial strain. Mothers experience significant emotional stress due to societal stigma and a lack of support, particularly from their husbands and family. Social isolation is prevalent, as mothers fear sharing their burdens and face physical confinement due to their children's needs. Financial strain is another major issue, with high medical costs adding to their economic difficulties. CONCLUSION The study emphasizes improved access to specialized care, awareness campaigns to reduce stigma, financial assistance, and stronger community support networks to support these mothers better. Addressing these unmet needs is crucial for empowering Pakistani mothers in their caregiving roles and improving the quality of life for their children with hydrocephalus.

Abstract
Background Complications associated with ventriculoperitoneal shunt insertion constitute a significant cause of morbidity and mortality among hydrocephalus patients. Despite this, VP shunt placement has remained the mainstay of treatment for hydrocephalus. The aim of this study is to evaluate the complications of VP shunt surgery in our environment and to identify the risk factors associated with it. Methodology Patients who had VP shunt surgery over a period of two years (Jan 2015-December 2016) were evaluated retrospectively by reviewing their hospital records. The patients' demography, aetiology and clinical presentation of the hydrocephalus, and complications were analysed using SPSS version 26.0. Results were presented in tables and figures. Results A total of 69 patients who had VP shunt over the study period had complete medical records available for review. Their age ranged between 2days and 68years with a male to female ratio of 1.8:1. Overall complication rate was 30.4%. Shunt malfunction (11.5%) and shunt infection (7.2%) were the commonest complications recorded. Late presentation was the most important risk factor for shunt complications. Conclusion The rate of shunt complications seen in this study compares fairly with studies in other parts of the world.

Abstract
OBJECTIVE There is no firm evidence regarding cerebrospinal fluid (CSF) shunt reimplantation after infection in the pediatric population. The purpose of this study was to compare different criteria and analyze new shunt failure. METHODS A cross-sectional retrospective multicenter study was performed over 6 years to study patients and each infected shunt at diagnosis, reimplantation, and after reimplantation. The patients were divided into 2 groups: group 1 (G1), reimplantation after negative serial CSF cultures during antibiotic treatment; group 2 (G2), reimplantation after negative serial pancultures after completion of antibiotics. The differences were measured with Mann-Whitney and Χ2 tests; multivariate analysis and associations were calculated using odds ratios (ORs) based on logistic regression. RESULTS There were 137 shunt infection events in 110 patients: 28 events in G1 and 109 in G2. Significant differences were observed in the diagnosis and reimplantation. Reimplantation dysfunction in G1 was 16 (55.17%) versus 30 (27.78%) in G2 (P = 0.006). The risk of shunt malfunction after reimplantation increased for G1 reimplantation criteria (P = 0.018; OR, 3.34; confidence interval [CI], 1.23-9.05): pleocytosis at diagnosis >17 cells (P = 0.036; OR, 2.41; CI, 1.06-5.47), CSF proteins at diagnosis >182 mg/dL (P = 0.049; OR, 2.21; CI, 1.00-4.89). CONCLUSIONS G2 reimplantation criteria were related to improved pleocytosis, CSF proteins, and blood neutrophils compared with G1. Mechanical and infectious dysfunction of the new shunt was 3 times more prevalent in G1 than in G2, considering the differences between the groups at diagnosis. Increased parameters of infection at diagnosis were associated with future malfunction more than parameters before reimplantation in both groups.

Abstract
Hydrocephalus is classically considered as a failure of cerebrospinal fluid (CSF) homeostasis that results in the active expansion of the cerebral ventricles. Infants with hydrocephalus can present with progressive increases in head circumference whereas older children often present with signs and symptoms of elevated intracranial pressure. Congenital hydrocephalus is present at or near birth and some cases have been linked to gene mutations that disrupt brain morphogenesis and alter the biomechanics of the CSF-brain interface. Acquired hydrocephalus can develop at any time after birth, is often caused by central nervous system infection or haemorrhage and has been associated with blockage of CSF pathways and inflammation-dependent dysregulation of CSF secretion and clearance. Treatments for hydrocephalus mainly include surgical CSF shunting or endoscopic third ventriculostomy with or without choroid plexus cauterization. In utero treatment of fetal hydrocephalus is possible via surgical closure of associated neural tube defects. Long-term outcomes for children with hydrocephalus vary widely and depend on intrinsic (genetic) and extrinsic factors. Advances in genomics, brain imaging and other technologies are beginning to refine the definition of hydrocephalus, increase precision of prognostication and identify nonsurgical treatment strategies.

Abstract
The brain's ventricles are filled with a colorless fluid known as cerebrospinal fluid (CSF). When there is an excessive accumulation of CSF in the ventricles, it can result in high intracranial pressure, ventricular enlargement, and compression of the surrounding brain tissue, leading to potential damage. This condition is referred to as hydrocephalus. Hydrocephalus is classified into two categories: congenital and acquired. Congenital hydrocephalus (CH) poses significant challenges for affected children and their families, particularly in resource-poor countries. Recognizing the psychological and economic impacts is crucial for developing interventions and support systems that can help alleviate the distress and burden faced by these families. As our understanding of CSF production and circulation improves, we are gaining clearer insights into the causes of CH. In this article, we will summarize the current knowledge regarding CSF circulation pathways and the underlying causes of CH. The main causes of CH include abnormalities in the FoxJ1 pathway of ventricular cilia, dysfunctions in the choroid plexus transporter Na+-K+-2Cl- contransporter isoform 1, developmental abnormalities in the cerebral cortex, and structural abnormalities within the brain. Understanding the causes of CH is indeed crucial for advancing research and developing effective treatment strategies. In this review, we will summarize the findings from existing studies on the causes of CH and propose potential research directions to further our understanding of this condition.

Abstract
BACKGROUND Hydrocephalus continues to pose significant clinical challenges in neurosurgery. The primary goal of this study is to assess the feasibility of ventriculocisternostomy (VCS) within the provincial city of Kinshasa and Mali to optimize the management of patients afflicted with hydrocephalus. METHODS This investigation was hosted at two major urban healthcare facilities: the Initiative Plus Hospital Center, positioned in the bustling metropolis of Kinshasa, Democratic Republic of the Congo (DRC), and the Bamako Hospital, Republic of Mali. A prospective, analytical cohort study was executed from December 2022 to June 2023. RESULTS In the Mali group, seven patients underwent VCS, four patients were treated with VCS and spinal surgery, and one case was treated with VCS and biopsy. Similarly, in the Kinshasa group, 25 patients underwent VCS, whereas four patients were treated with VCS and spinal surgery. The median hospital stay was eight and 10 days for the Mali and the Kinshasa groups, respectively. CONCLUSION VCS emerges as a formidable alternative for hydrocephalus management in Mali and DRC, showcasing the potential to markedly ameliorate patient outcomes, economize healthcare expenditures, and fortify the local neurosurgical capacity.

Abstract
BACKGROUND At Red Cross War Memorial Children's Hospital (RCCH), it is the preferred practice to use non-ventriculoperitoneal (non-VP) shunts when the peritoneum is ineffective or contraindicated for cerebrospinal fluid (CSF) diversion and when endoscopy is not an option. The objective of this study is to evaluate the clinical course of patients having undergone these procedures. METHOD A single-centre retrospective review at RCCH wherein 43 children with a total of 59 episodes of non-VP shunt placement over a 12-year period were identified for inclusion. RESULTS Twenty-five ventriculoatrial (VA) and 32 ventriculopleural (VPL) shunts were analysed with a median age at insertion of 2.9 (0.3-14.9) and 5.3 years (0.5-13.4), respectively. The median number of previous shunt procedures prior to VA or VPL shunt insertion was 6.0 (2-28) versus 4.5 (2-17), respectively. Three VA (12.0%) and three VPL (9.4%) shunt patients were lost to follow-up. Of those remaining, 10 VA shunts (45.5%) compared to 19 (65,5%) VPL shunts required revision. One ventriculovesical shunt and one ventriculocholecystic shunt were placed in the same patient after 21 and 25 shunt-related procedures, respectively, and both were revised within 3 weeks of insertion. Median shunt survival was 8 months longer for the VA compared to the VPL shunts, being 13.5 (0-67) and 5 months (0-118), respectively. Complications for VA shunts were low, with the overall shunt sepsis rate in the VA group at 4% (n = 1) compared to 15.6% (n = 5) in the VPL group. CONCLUSION Our findings support that VA and VPL shunts are acceptable second-line options in an already compromised group of patients where safe treatment options are limited, provided attention is paid to the technical details specific to their placement.

Comparative Scoping Review of Prenatal Care Resources for Families of Children With Spinal Dysraphism and Hydrocephalus in High-Income Countries and Low- and Middle-Income Countries. Neurosurgery 2024; 94:657-665. [PMID: 37947403 DOI: 10.1227/neu.0000000000002750] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Accepted: 09/02/2023] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Low- and middle-income countries (LMICs) face higher incidences and burdens of care for neural tube defects (NTDs) and hydrocephalus compared with high-income countries (HICs), in part due to limited access to neurosurgical intervention. In this scoping review, we aim to integrate studies on prenatal care, counseling, and surgical management for families of children with spinal dysraphism and hydrocephalus in LMICs and HICs. METHODS PubMed, Embase, Global Index Medicus, and Web of Science electronic databases were searched for English language articles pertaining to prenatal care, counseling, and surgical management for families of children with spinal dysraphism and hydrocephalus in HICs and LMICs. Identified abstracts were screened for full-text review. Studies meeting inclusion criteria were reviewed in full and analyzed. RESULTS Seventy studies met the inclusion criteria. Twelve studies (16.9%) were conducted in HICs only, 50 studies (70.4%) were conducted in LMICs only, and 9 studies (12.7%) encompassed both. On thematic analysis, seven underlying topics were identified: epidemiology, folate deficiency and supplementation/fortification, risk factors other than folate deficiency, prenatal screening, attitudes and perceptions about NTDs and their care, surgical management, and recommendations for guideline implementation. CONCLUSION NTDs have become a widely acknowledged public health problem in many LMICs. Prenatal counseling and care and folate fortification are critical in the prevention of spinal dysraphism. However, high-quality, standardized studies reporting their epidemiology, prevention, and management remain scarce. Compared with NTDs, research on the prevention and screening of hydrocephalus is even further limited. Future studies are necessary to quantify the burden of disease and identify strategies for improving global outcomes in treating and reducing the prevalence of NTDs and hydrocephalus. Surgical management of NTDs in LMICs is currently limited, but pediatric neurosurgeons may be uniquely equipped to address disparities in the care and counseling of families of children with spinal dysraphism and hydrocephalus.

Abstract
BACKGROUND Congenital hydrocephalus is a significant challenge in neurosurgery, particularly in resource-limited settings. This study focuses on the congenital hydrocephalus in Brazil, a developing country, over the past 13 years. METHODS This study is a retrospective analysis of congenital hydrocephalus treatment and outcomes using data records on DATASUS from January 2008 to July 2021. Demographics, cost of hospitalizations, amount paid to professionals, mortality, and mean length of stay (LOS) were analyzed. Statistical analysis was conducted to determine significant associations between these indicators and pediatric hydrocephalus. RESULTS DATASUS recorded 8493 cases of congenital hydrocephalus in the studied period, with a prevalence of 24.28 per 100,000 newborns, mostly linked to spina bifida. Congenital hydrocephalus caused 60.83 ± 13.98 neonatal deaths per year, with the highest rate among 32-36 weeks gestational age. Acquired hydrocephalus led to 1063 infant deaths, whereas congenital hydrocephalus resulted in 3122 deaths, with no clear trend by the years. White infants had the highest mortality. A total of 33,184 shunt procedures were performed, with an average cost of $715.37 per procedure. The mortality model showed no significant effects of cost or professionals' salary, but a significant effect of LOS on hospitalization costs was observed. CONCLUSIONS Pediatric hydrocephalus in Brazil's public health system is a significant burden. Congenital hydrocephalus prevalence and mortality emphasize the need for early diagnosis and treatment. Early diagnosis, prenatal care, and adequate resources are crucial. This study offers insights into congenital hydrocephalus, highlighting challenges and future directions for improved care.

Abstract
Congenital hydrocephalus after peripartum infection usually presents early in life; however, we present a 92-year-old female patient with newly diagnosed hydrocephalus secondary to peripartum infection. Intracranial imaging showed ventriculomegaly, calcifications bilaterally throughout the cerebral hemispheres, and findings suggesting a chronic process. This presentation is most likely to occur in low-resource settings, and given the risks of operation, conservative management was preferred.

Abstract
Hydrocephalus occurs when the cerebrospinal fluid (CSF) accumulates in the cerebral ventricles. This is due to either obstruction in the CSF flow, decreasing its absorption by the arachnoid villus to the Dural venous sinuses, or increasing production of the CSF. The most disproportionately and severely affected by the disease consequences are African children. This is because of the high incidence of postinfectious hydrocephalus and spinal dysraphism compared with other world children. The health care system in Africa has access to 488 neurosurgeons which represents less than 1% of the global neurosurgeons, thus pediatric hydrocephalus is considered an emerging public health problem in Africa because of the difficulty of the patient's access to proper care. Numerous studies conducted in Africa have revealed a significant imbalance in the distribution of neurosurgical resources across the continent. Specifically, South Africa and North Africa collectively account for 86% of the total practicing neurosurgeons, indicating a pronounced concentration of these specialized medical professionals in these regions. Having an abundance of case studies regarding hydrocephalus is vital to increase our awareness and understanding. Hydrocephalus should gain more priority by current policymakers as an important health concern. This may be achieved by proper resource allocation to ensure better quality means of diagnosis, intervention, and rehabilitation.

Abstract
BACKGROUND Congenital anomalies are a leading cause of morbidity and mortality worldwide. We aimed to review the common surgically correctable congenital anomalies with recent updates on the global disease burden and identify the factors affecting morbidity and mortality. METHOD A literature review was done to assess the burden of surgical congenital anomalies with emphasis on those that present within the first 8000 days of life. The various patterns of diseases were analyzed in both low- and middle-income countries (LMIC) and high-income countries (HIC). RESULTS Surgical problems such as digestive congenital anomalies, congenital heart disease and neural tube defects are now seen more frequently. The burden of disease weighs more heavily on LMIC. Cleft lip and palate has gained attention and appropriate treatment within many countries, and its care has been strengthened by global surgical partnerships. Antenatal scans and timely diagnosis are important factors affecting morbidity and mortality. The frequency of pregnancy termination following prenatal diagnosis of a congenital anomaly is lower in many LMIC than in HIC. CONCLUSION Congenital heart disease and neural tube defects are the most common congenital surgical diseases; however, easily treatable gastrointestinal anomalies are underdiagnosed due to the invisible nature of the condition. Current healthcare systems in most LMICs are still unprepared to tackle the burden of disease caused by congenital anomalies. Increased investment in surgical services is needed.

Abstract
PURPOSE Pediatric hydrocephalus is a common and challenging condition. To date, the ventriculoperitoneal shunt (VPS) is still the main lifesaving treatment option. Nonetheless, it remains imperfect and is associated with multiple short- and long-term complications. This paper is a reflective review of the current state of the VPS, our knowledge gaps, and the future state of shunts in neurosurgical practice. METHODS AND RESULTS The authors' reflections are based on a review of shunts and shunt-related literature. CONCLUSION Overall, there is still an urgent need for the neurosurgical community to actively improve current strategies for shunt failures and shunt-related morbidity. The authors emphasize the role of collaborative efforts amongst like-minded clinicians to establish pragmatic approaches to avoid shunt complications.

Abstract
INTRODUCTION Hydrocephalus and myelomeningocele (MMC) place disproportionate burdens of disease on low-income and middle-income countries (LMICs). MMC-associated hydrocephalus and its sequelae result in a spectrum of severely devastating clinical manifestations, for which LMICs are disproportionately unprepared in terms of human, capital and technological resources. This study aims to review and compare the management and outcomes of infant MMC-associated hydrocephalus in LMICs and high-income countries. METHODS AND ANALYSIS This systematic review and meta-analysis will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The following databases will be searched without restrictions on language, publication date or country of origin: EMBASE, MEDLINE, The Cochrane Library, Global Index Medicus, African Journals Online and SciELO. All peer-reviewed studies of primary data reporting management and outcomes of infant MMC-associated hydrocephalus will be included. Where high-quality homogeneous studies exist, meta-analyses will be conducted to compare the management and outcomes of MMC-associated hydrocephalus across socioeconomic and geographical regions of the world. The primary outcome will be treatment failure of the first-line hydrocephalus treatment, which we defined operationally as the performance of a second intervention for the same reason as the first. Secondary outcomes include time to failure, rates of mortality and postoperative complications. ETHICS AND DISSEMINATION Ethical approval was not applicable because this study does not involve human participants. Dissemination strategies will include publication in a peer-reviewed journal, oral and poster presentations at conferences and an interactive web application to facilitate interaction with the findings and promote the discussion and sharing of findings on social media.

Abstract
Children in Africa are disproportionately burdened by the neurosurgical condition hydrocephalus. In Blantyre, Malawi, paediatric hydrocephalus represents the majority of surgical procedures performed in the neurosurgical department at Queen Elizabeth Central Hospital. To reduce morbidity and mortality, timely detection followed by referral from surrounding primary health centres is crucial. Aiming to explore perceptions and identify enablers and barriers to detection and referral, we conducted a qualitative study among primary healthcare providers (n = 30) from ten health centres in Blantyre district. Using a semi-structured interview-guide, we audio-recorded and transcribed the interviews before conducting a thematic analysis. One main finding is that there is a potential to improve detection through head circumference measurements, which is the recommended way to detect hydrocephalus early, yet healthcare providers did not carry this out systematically. They described the health passport provided by the Malawian Ministry of Health as an important tool for clinical communication. However, head circumference growth charts are not included. To optimise outcomes for paediatric hydrocephalus we suggest including head circumference growth charts in the health passports. To meet the need for comprehensive management of paediatric hydrocephalus, we recommend more research from the continent, focusing on bridging the gap between primary care and neurosurgery.

Abstract
Hydrocephalus is a serious condition that affects patients of all ages, resulting from a multitude of causes. While the etiologies of hydrocephalus are numerous, many of the acute and chronic symptoms of the condition are shared. These symptoms include disorientation and pain (headaches), cognitive and developmental changes, vision and sleep disturbances, and gait abnormalities. This collective group of symptoms combined with the effectiveness of CSF diversion as a surgical intervention for many types of the condition suggest that the various etiologies may share common cellular and molecular dysfunctions. The incidence rate of pediatric hydrocephalus is approximately 0.1-0.6% of live births, making it as common as Down syndrome in infants. Diagnosis and treatment of various forms of adult hydrocephalus remain understudied and underreported. Surgical interventions to treat hydrocephalus, though lifesaving, have a high incidence of failure. Previously tested pharmacotherapies for the treatment of hydrocephalus have resulted in net zero or negative outcomes for patients potentially due to the lack of understanding of the cellular and molecular mechanisms that contribute to the development of hydrocephalus. Very few well-validated drug targets have been proposed for therapy; most of these have been within the last 5 years. Within the last 50 years, there have been only incremental improvements in surgical treatments for hydrocephalus, and there has been little progress made towards prevention or cure. This demonstrates the need to develop nonsurgical interventions for the treatment of hydrocephalus regardless of etiology. The development of new treatment paradigms relies heavily on investment in researching the common molecular mechanisms that contribute to all of the forms of hydrocephalus, and requires the concerted support of patient advocacy organizations, government- and private-funded research, biotechnology and pharmaceutical companies, the medical device industry, and the vast network of healthcare professionals.

Cerebrospinal fluid hydrocephalus shunting: cisterna magna, ventricular frontal, ventricular occipital. Neurosurg Rev 2022; 45:2615-2638. [PMID: 35513737 DOI: 10.1007/s10143-022-01798-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 04/08/2022] [Accepted: 04/21/2022] [Indexed: 10/18/2022]
Abstract
Despite advances in cerebrospinal fluid shunting technology, complications remain a significant concern. There are some contradictions about the effectiveness of proximal catheter entry sites that decrease shunt failures. We aim to compare efficiency of shunts with ventricular frontal, ventricular occipital, and cisterna magna entry sites. The systemic search was conducted in the database from conception to February 16, 2022 following guidelines of PRISMA. Between 2860 identified articles, 24 articles including 6094 patients were used for data synthesis. The aggregated results of all patients showed that "overall shunt failure rate per year" in mixed hydrocephalus with ventricular frontal and occipital shunts, and cisterna magna shunt (CMS) were 9.0%, 12.6%, and 30.7%, respectively. The corresponding values for "shunt failure rate" due to obstruction were 15.3%, 31.5%, and 10.2%, respectively. The similar results for "shunt failure rate" due to infection were 11.3%, 9.1%, and 27.2%, respectively. The related values for "shunt failure rate" due to overdrainage were 2.9%, 3.9%, and 13.6%, respectively. CMS was successful in the immediate resolution of clinical symptoms. Shunting through an occipital entry site had a greater likelihood of inaccurate catheter placement and location. Contrary to possible shunt failure due to overdrainage, the failure likelihood due to obstruction and infection in pediatric patients was higher than that of mixed hydrocephalus patients. In both mixed and pediatric hydrocephalus, obstruction and overdrainage were the most and least common complications of ventricular frontal and occipital shunts, respectively. The most and least common complications of mixed CMS were infection and obstruction, respectively.

Abstract
OBJECTIVES In this study, we present data from a neurosurgical training program in Tanzania for the treatment of pediatric hydrocephalus. The objectives of the study were to identify the demographics and clinical characteristics of pediatric patients with hydrocephalus who were admitted to Bugando Medical Centre in Mwanza, Tanzania, as well as to describe their surgical treatment and early clinical outcomes. METHODS This cross-sectional study included 38 pediatric patients. Physical examinations were conducted pre- and postoperatively, and their mothers completed a questionnaire providing demographic and clinical characteristics. RESULTS There was a slight preponderance of male sex (21/38; 55.3%) with median age at the time of admission of 98.5 days. The majority of patients were surgically treated (33/38; 86.8%). Among those surgically treated, most received a ventriculoperitoneal shunt (23/33; 69.7%), whereas 7 were treated with an endoscopic third ventriculostomy (7/33; 21.2%). At the time of admission, the majority of patients (86%) had head circumferences that met criteria for macrocephaly. The median time between admission and surgery was 23 days (2-49 days). Overall, 5 patients (13.2%) died, including 2 who did not receive surgical intervention. CONCLUSIONS We found that in our population, pediatric patients with hydrocephalus often present late for treatment with additional significant delays prior to receiving any surgical intervention. Five patients died, of whom 2 had not undergone surgery. Our study reinforces that targeted investments in clinical services are needed to enable access to care, improve surgical capacity, and alleviate the burden of neurosurgical disease from pediatric hydrocephalus in sub-Saharan Africa.

Abstract
Infant hydrocephalus poses a severe global health burden; 80% of cases occur in the developing world where patients have limited access to neurosurgical care. Surgical treatment combining endoscopic third ventriculostomy and choroid plexus cauterization (ETV/CPC), first practiced at CURE Children's Hospital of Uganda (CCHU), is as effective as standard ventriculoperitoneal shunt (VPS) placement while requiring fewer resources and less post-operative care. Although treatment focuses on controlling ventricle size, this has little association with treatment failure or long-term outcome. This study aims to monitor the progression of hydrocephalus and treatment response, and investigate the association between cerebral physiology, brain growth, and neurodevelopmental outcomes following surgery. We will enroll 300 infants admitted to CCHU for treatment. All patients will receive pre/post-operative measurements of cerebral tissue oxygenation (SO2), cerebral blood flow (CBF), and cerebral metabolic rate of oxygen consumption (CMRO2) using frequency-domain near-infrared combined with diffuse correlation spectroscopies (FDNIRS-DCS). Infants will also receive brain imaging, to monitor tissue/ventricle volume, and neurodevelopmental assessments until two years of age. This study will provide a foundation for implementing cerebral physiological monitoring to establish evidence-based guidelines for hydrocephalus treatment. This paper outlines the protocol, clinical workflow, data management, and analysis plan of this international, multi-center trial.

Clin Neurol Neurosurg 2021; 212:107091. [PMID: 34922292 DOI: 10.1016/j.clineuro.2021.107091] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 12/06/2021] [Accepted: 12/10/2021] [Indexed: 01/10/2023]
Abstract
INTRODUCTION Congenital and infantile hydrocephalus are assumed to be major contributors to pediatric morbidity, mortality and functional disability in low-income countries. Despite this, epidemiologic data and the overview of neurodevelopmental outcomes in these regions is very limited. We aimed to pilot the use of a wide range of more locally suitable tools to assess neurodevelopment to understand whether they were feasible for use and could provide estimates of developmental delay and poor functioning in a population of children with hydrocephalus in Malawi. METHODS We conducted a prospective observational cohort study, at the tertiary neurosurgery clinic in Blantyre, Malawi in 2018, recruiting consecutive children with congenital and infantile hydrocephalus who were previously treated with ventriculoperitoneal shunts and endoscopic third ventriculostomy (ETV) in the neurosurgery unit of the hospital. We assessed demographic details, and gained information on children's functioning using the Liverpool Outcome Score (LOS), and the Eating and Drinking Ability Classification System as well as full anthropometric assessment and child development with the Malawi Developmental Assessment Tool (MDAT). RESULTS All tools were feasible for use, easy to train on, could be used for assessing children with hydrocephalus and were suitable to adapt for our environment. We evaluated 41 children, aged 2-60 months with a mean age of 22.6 months (interquartile range [IQR] = 8.3 months -36.5 months). Functional assessment using the Liverpool Outcome Score showed the majority of children 92.7% (CI 80.1-98.5, n = 38) had severe sequelae from the hydrocephalus and were dependent on their parents or caregivers. Only 27 children (65.9%, CI 49.4, 80.0) had full or expected control of their bowel and bladder and 6 children (14.6%, CI 5.6, 29.2), had a recent history of seizures. About two thirds (63.4% CI 45.0-77.9, n = 26/41) of children were able to eat and to drink safely and efficiently. Over two thirds of the children (70.7%, CI 56.8, 84.6, n = 29) were stunted and almost half of the cohort underweight (43.9%,(CI 28.5, 60.3, n = 18). Almost half 48.8% (CI 32.9, 64.9, n = 20/41) had developmental delay on MDAT with 41.5% (CI 26.4, 56.6, n = 17/41) graded as severely delayed (-<2sd on developmental age z score). We found significant associations between dependence identified by the LOS and developmental delay according to the MDAT (p = 0.014, Pearson's chi-squared test). CONCLUSION This pilot study demonstrates that the assessment tools we used identified a high proportion of children with hydrocephalus as having functional difficulties, stunted growth and developmental delay, in Malawi. Use of these tools can now be scaled up and will be helpful to support research in understanding what factors contribute to poor functioning, growth and development in these cohorts and help us to investigate what strategies may prevent and support children with hydrocephalus in African settings.

Abstract
(1) Background: pediatric hydrocephalus is a challenging condition. Programmable shunt valves (PSV) have been increasingly used. This study is undertaken to firstly, to objectively evaluate the efficacy of PSV as a treatment modality for pediatric hydrocephalus; and next, review its associated patient outcomes at our institution. Secondary objectives include the assessment of our indications for PSV, and corroboration of our results with published literature. (2) Methods: this is an ethics-approved, retrospective study. Variables of interest include age, gender, hydrocephalus etiology, shunt failure rates and incidence of adjustments made per PSV. Data including shunt failure, implant survival, and utility comparisons between PSV types are subjected to statistical analyses. (3) Results: in this case, 51 patients with PSV are identified for this study, with 32 index and 19 revision shunts. There are 3 cases of shunt failure (6%). The mean number of adjustments per PSV is 1.82 times and the mean number of adjustments made per PSV is significantly lower for MEDTRONIC™ Strata PSVs compared with others (p = 0.031). Next, PSV patients that are adjusted more frequently include cases of shunt revisions, PSVs inserted due to CSF over-drainage and tumor-related hydrocephalus. (4) Conclusion: we describe our institutional experience of PSV use in pediatric hydrocephalus and its advantages in a subset of patients whose opening pressures are uncertain and evolving.

Abstract
Reparative inflammation is an important protective response that eliminates foreign organisms, damaged cells, and physical irritants. However, inappropriately triggered or sustained inflammation can respectively initiate, propagate, or prolong disease. Post-hemorrhagic (PHH) and post-infectious hydrocephalus (PIH) are the most common forms of hydrocephalus worldwide. They are treated using neurosurgical cerebrospinal fluid (CSF) diversion techniques with high complication and failure rates. Despite their distinct etiologies, clinical studies in human patients have shown PHH and PIH share similar CSF cytokine and immune cell profiles. Here, in light of recent work in model systems, we discuss the concept of "inflammatory hydrocephalus" to emphasize potential shared mechanisms and potential therapeutic vulnerabilities of these disorders. We propose that this change of emphasis could shift our thinking of PHH and PIH from a framework of life-long neurosurgical disorders to that of preventable conditions amenable to immunomodulation.

Abstract
In the twenty-first century, choroid plexus cauterization (CPC) in combination with endoscopic third ventriculostomy (ETV) has emerged as an effective treatment for some infants with hydrocephalus, leading to the favourable condition of 'shunt independence'. Herein we provide a narrative technical review considering the indications, procedural aspects, morbidity and its avoidance, postoperative care and follow-up. The CP has been the target of hydrocephalus treatment for more than a century. Early eminent neurosurgeons including Dandy, Putnam and Scarff performed CPC achieving generally poor results, and so the procedure fell out of favour. In recent years, the addition of CPC to ETV was one of the reasons greater ETV success rates were observed in Africa, compared to developed nations, and its popularity worldwide has since increased. Initial results indicate that when ETV/CPC is performed successfully, shunt independence is more likely than when ETV is undertaken alone. CPC is commonly performed using a flexible endoscope via septostomy and aims to maximally cauterize the CP. Success is more likely in infants aged >1 month, those with hydrocephalus secondary to myelomeningocele and aqueductal obstruction and those with >90% cauterized CP. Failure is more likely in those with post-haemorrhagic hydrocephalus of prematurity (PHHP), particularly those <1 month of corrected age and those with prepontine scarring. High-quality evidence comparing the efficacy of ETV/CPC with shunting is emerging, with data from ongoing and future trials offering additional promise to enhance our understanding of the true utility of ETV/CPC.

Abstract
Objective: The aim of this study is to compare specific three-institution, cross-country data that are relevant to the Global Surgery indicators and the functioning of health systems. Methods: We retrospectively reviewed the clinical and socioeconomic characteristics of pediatric patients who underwent cerebrospinal fluid (CSF) diversion surgery for hydrocephalus in three different centers: the University of Tsukuba Hospital in Ibaraki, Japan (HIC), the Jose R. Reyes Memorial Medical Center in Manila, Philippines [low-to-middle-income country (LMIC)], and the Federal Neurosurgical Center in Novosibirsk, Russia (UMIC). The outcomes of interest were the timing of CSF diversion surgery and mortality. Statistical tests included descriptive statistics, Cox proportional hazards model, and logistic regression. Nation-level data were also obtained to provide the relevant socioeconomic contexts in discussing the results. Results: In total, 159 children were included, where 13 are from Japan, 99 are from the Philippines, and 47 are from the Russian Federation. The median time to surgery at the specific neurosurgical centers was 6 days in the Philippines and 1 day in both Japan and Russia. For the cohort from the Philippines, non-poor patients were more likely to receive CSF diversion surgery at an earlier time (HR = 4.74, 95% CI 2.34-9.61, p <0.001). In the same center, those with infantile or posthemorrhagic hydrocephalus (HR = 3.72, 95% CI 1.70-8.15, p = 0.001) were more likely to receive CSF diversion earlier compared to those with congenital hydrocephalus, and those with postinfectious (HR = 0.39, 95% CI 0.22-0.70, p = 0.002) or myelomeningocele-associated hydrocephalus (HR = 0.46, 95% CI 0.22-0.95, p = 0.037) were less likely to undergo surgery at an earlier time. For Russia, older patients were more likely to receive or require early CSF diversion (HR = 1.07, 95% CI 1.01-1.14, p = 0.035). External ventricular drain (EVD) insertion was found to be associated with mortality (cOR 14.45, 95% CI 1.28-162.97, p = 0.031). Conclusion: In this study, Filipino children underwent late time-interval of CSF diversion surgery and had mortality differences compared to their Japanese and Russian counterparts. These disparities may reflect on the functioning of the health systems of respective countries.

Cumulative Damage: Cell Death in Posthemorrhagic Hydrocephalus of Prematurity. Cells 2021; 10:cells10081911. [PMID: 34440681 PMCID: PMC8393895 DOI: 10.3390/cells10081911] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 07/23/2021] [Accepted: 07/25/2021] [Indexed: 12/19/2022] Open
Abstract
Globally, approximately 11% of all infants are born preterm, prior to 37 weeks’ gestation. In these high-risk neonates, encephalopathy of prematurity (EoP) is a major cause of both morbidity and mortality, especially for neonates who are born very preterm (<32 weeks gestation). EoP encompasses numerous types of preterm birth-related brain abnormalities and injuries, and can culminate in a diverse array of neurodevelopmental impairments. Of note, posthemorrhagic hydrocephalus of prematurity (PHHP) can be conceptualized as a severe manifestation of EoP. PHHP impacts the immature neonatal brain at a crucial timepoint during neurodevelopment, and can result in permanent, detrimental consequences to not only cerebrospinal fluid (CSF) dynamics, but also to white and gray matter development. In this review, the relevant literature related to the diverse mechanisms of cell death in the setting of PHHP will be thoroughly discussed. Loss of the epithelial cells of the choroid plexus, ependymal cells and their motile cilia, and cellular structures within the glymphatic system are of particular interest. Greater insights into the injuries, initiating targets, and downstream signaling pathways involved in excess cell death shed light on promising areas for therapeutic intervention. This will bolster current efforts to prevent, mitigate, and reverse the consequential brain remodeling that occurs as a result of hydrocephalus and other components of EoP.

Abstract
Introduction Hydrocephalus remains a common condition with significant patient morbidity; however, accurate accounting of the incidence of this disease as well as of the impact of hospital volume on outcome remains limited. Methods The National Inpatient Sample was used to evaluate patients who underwent surgical treatment of hydrocephalus from 2009-2013. Patient demographics (e.g., length of stay, disposition, charges), and the impact of hospital volume on outcomes were evaluated. Results A total of 156,205 patients were identified. Ventriculoperitoneal (VP) shunting the most common type of device (35.8%) followed by shunt replacement (23.9%). Treatment charges for hydrocephalus were $332 million in 2009 and $418 million in 2013 nationally. High-volume hospitals had more routine discharges compared with lower-volume hospitals (65.7% vs. 50.9%, p<0.0001), which was a trend that improved over time. Multivariate analysis confirmed that hospital volume was independently associated with routine disposition after adjusting for other factors such as patient age, length of stay, and shunt type. However, hospital volume showed a small association with length of stay (β = -0.05, p = 0.0001) and did not impact hospital charges on multivariate analysis. Conclusion This analysis provides a recent update of hydrocephalus epidemiology, trends, and outcomes nationally. Estimates from this study suggest that hydrocephalus is a common and costly problem. Hospital volume was for the first time to be associated with important differences in patient outcomes.

Abstract
OBJECTIVE Global neurosurgery is the practice of neurosurgery with the primary purpose of delivering timely, safe, and affordable neurosurgical care to all who need it. The aim of this study is to identify the most frequently cited articles in global neurosurgery through a bibliographic review to characterize articles and trends around this growing topic. METHODS The top most-cited articles in global neurosurgery were determined by searching the Web of Science database using a priori search terms. Articles with at least 5 citations were selected, and there were no time period or language restrictions. The data were extracted from each included article and all characteristics were summarized. RESULTS A total of 932 articles were identified using the search terms; 69 articles fulfilled inclusion criteria and 17 articles were selected that had more than 5 citations. The articles' number of citations ranged from 6 to 98 for the most-cited article. Authors from, or affiliated with, 14 countries contributed to the 17 articles, and the country that had the greatest representation was the United States. The main topic discussed was surgical capacity, the second topic was the treatment of different neurosurgical conditions, and volunteerism was the third topic. CONCLUSIONS There is currently a deficit in both the amount of literature surrounding the topic of global neurosurgery and how much that literature is cited. Developing innovative ways to increase academic productivity within, or in collaboration with, low-middle income countries is essential to contribute to global neurosurgery.

Abstract
Neonatal and infant hydrocephalus is an important factor for mortality and morbidity in developing countries with limited diagnostic and therapeutic means. The purpose of this study was to report our experience in the management of this disease in Mauritania. We conducted a retrospective study of 126 medical records of newborns aged 0-24 months treated for hydrocephalus in the Department of Neurosurgery at the Nouakchott National Hospital from June 2014 to June 2018. Mean follow-up time was 15 months (9-27 months). The average age of patients was 5 months (2 days-20 months). Highest prevalence was observed among female babies (sex ratio 0.77). Our case series consisted of 45 newborns (35.7%) and 81 infants (64.3%). A history of infection during pregnancy was found in 19.8% of cases and neonatal infection in 23.8% of cases. Clinically, 87.3% had macrocephalus, 35.7% had psychomotor retardation and 15.8% refused to suckle. The main cause was myelomeningocele (23.8%), followed by meningitis (15.8%). Ventriculo-peritoneal derivation (VPD) was the first-line treatment in newborns (68.8%), while endoscopic ventriculocisternostomy (EDV) was the preferred approach in infants (74.1%). Overall complication rate was 26.1% (57.6% for VPD and 4.1% for EDV). Hydrocephalus is the most common disease treated by paediatric neurosurgeons in Africa. Management is usually delayed, hence the importance of prevention, especially of neural tube defects and infections.

Abstract
PURPOSE In hydrocephalic children, regular investigations of the ventricles are important for initial diagnosis and after initial treatment. Our recent study showed that changes of the third ventricle diameter (TVD) reliably reflect changes of the entire ventricular system at diagnosis and following initial therapy. This study compares changes of TVD with changes of ventricle indices at acute shunt failure and after shunt revision in hydrocephalic children. METHODS A total of 117 children with hydrocephalus were included in this study. MRI/CT images of 30 children were evaluated at the time of acute shunt dysfunction and after subsequent shunt revision. Measurements included axial TVD and three standard measures of lateral ventricles (Evans index, frontal occipital horn ratio (FOHR), and cella media index (CMI)). In 97 children, correlation between axial and coronal/diagonal TVD was evaluated at the time of initial diagnosis of hydrocephalus. RESULTS At acute shunt dysfunction, the best linear correlation was found between TVD and CMI (r = 0.702, p < 0.01). Changes of TVD correlated very well to changes of FOHR (r = 0.74, p < 0.01) after shunt revision. The correlation between axial and coronal/diagonal TVD was outstanding (r = 0.995, p < 0.01). CONCLUSION TVD showed a significant correlation with all lateral ventricle indices at acute shunt dysfunction and after shunt revision. It is therefore not only an excellent mirror of ventricular changes at initial hydrocephalus diagnosis and therapy, but it can also reliably reflect changes of the ventricular system in relevant clinical situations associated with the lifelong treatment of pediatric hydrocephalus.

Abstract
Hydrocephalus is the most common neurosurgical disorder worldwide and is characterized by enlargement of the cerebrospinal fluid (CSF)-filled brain ventricles resulting from failed CSF homeostasis. Since the 1840s, physicians have observed inflammation in the brain and the CSF spaces in both posthaemorrhagic hydrocephalus (PHH) and postinfectious hydrocephalus (PIH). Reparative inflammation is an important protective response that eliminates foreign organisms, damaged cells and physical irritants; however, inappropriately triggered or sustained inflammation can respectively initiate or propagate disease. Recent data have begun to uncover the molecular mechanisms by which inflammation - driven by Toll-like receptor 4-regulated cytokines, immune cells and signalling pathways - contributes to the pathogenesis of hydrocephalus. We propose that therapeutic approaches that target inflammatory mediators in both PHH and PIH could address the multiple drivers of disease, including choroid plexus CSF hypersecretion, ependymal denudation, and damage and scarring of intraventricular and parenchymal (glia-lymphatic) CSF pathways. Here, we review the evidence for a prominent role of inflammation in the pathogenic mechanism of PHH and PIH and highlight promising targets for therapeutic intervention. Focusing research efforts on inflammation could shift our view of hydrocephalus from that of a lifelong neurosurgical disorder to that of a preventable neuroinflammatory condition.

Abstract
Background In sub-Saharan Africa, there is a growing awareness of the burden of paediatric surgical diseases. This has highlighted the large discrepancy between the capacity to treat and the ability to afford treatment, and the effect of this problem on access to care. This review focuses on the sources and challenges of funding paediatric surgical procedures in sub-Saharan Africa. Methods We undertook a search for studies published between January 2007 and November 2016 that reported the specific funding of paediatric surgical procedures and were conducted in sub-Saharan Africa. Abstract screening, full-text review and data abstraction were completed and resulting data were analysed using Statistical Package for Social Sciences (SPSS) software. Results Thirty-five studies met our inclusion criteria and were reviewed. The countries that were predominantly emphasized in the publications reviewed were Nigeria, South Africa, Kenya, Ghana and Uganda. The paediatric surgical procedures involved general paediatric surgery/urology, cardiac surgery, neurosurgery, oncology, plastics, ophthalmology, orthopaedics and otorhinolaryngology. The mean cost of these procedures ranged from 60 to 21,140 United States Dollars (USD). The source of funding for these procedures was mostly out-of-pocket payments (OOPs) by the patient's family in 32 studies, (91.4%) and medical mission/non-governmental organizations (NGOs) in 21 (60%) studies. This pattern did not differ appreciably between the articles published in the initial and latter 5 years of the study period, although there was a trend towards a reduction in OOP funding. Improvements in healthcare funding by individual countries supported by international organizations and charities were the predominant suggested solutions to challenges in funding. Conclusion While considering the potential limitations created by diversity in study design, the reviewed publications indicate that funding for paediatric surgical procedures in sub-Saharan Africa is mostly by OOPs made by families of the patients. This may result in limited access to some procedures. Coordinated efforts, and collaboration between individual countries and international agencies, may help to reduce OOP funding and thus improve access to critical procedures.

Abstract
Introduction: Hydrocephalus is one of the most common diseases in children, and its treatment requires brain operation. However, the pathophysiology of the disease is very complicated and still unknown. Methods: Endoscopic Third Ventriculostomy (ETV) and Ventriculoperitoneal Shunt (VPS) implantation are among the common treatments of hydrocephalus. In this study, Cerebrospinal Fluid (CSF) hydrodynamic parameters and efficiency of the treatment methods were compared with numerical simulation and clinical follow-up of the treated patients. Results: Studies have shown that in patients under 19 years of age suffering from hydrocephalus related to a Posterior Fossa Brain Tumor (PFBT), the cumulative failure rate was 21% and 29% in ETV and VPS operation, respectively. At first, the ETV survival curve shows a sharp decrease and after two months it gets fixed while VPS curve makes a gradual decrease and reaches to a level lower than ETV curve after 5.7 months. Post-operative complications in ETV and VPS methods are 17% and 31%, respectively. In infants younger than 12 months with hydrocephalus due to congenital Aqueduct Stenosis (AS), and also in the elderly patients suffering from Normal Pressure Hydrocephalus (NPH), ETV is a better treatment option. Computer simulations show that the maximum CSF pressure is the most reliable hydrodynamic index for the evaluation of the treatment efficacy in these patients. After treatment by ETV and shunt methods, CSF pressure decreases about 9 and 5.3 times, respectively and 2.5 years after shunt implantation, this number returns to normal range. Conclusion: In infants with hydrocephalus, initial treatment by ETV was more reasonable than implanting the shunt. In adult with hydrocephalus, the initial failure in ETV occurred sooner compared to shunt therapy; however, ETV was more efficient.

Abstract
Introduction: Hydrocephalus (HCP) remains one of the commonest pathologies treated in developing countries. Endoscopic third ventriculostomy (ETV) has become the alternative to shunt-divergen procedures in the treatment of many pathologies of the cerebral fluid in the brain. Age has been considered a limitation to perform the procedure, we started to perform ETV In younger patients earlier than many other units. Objectives: In this study, we demonstrate the overall efficacy of ETV in infants younger than 1-year of age and to subsequently report the outcome of this procedure. Methods: From 2000 till 2016 we have performed a total of 386 cases of ETV of all ages. 71-cases were infants (below 1-year of age). Our study was undertaken to evaluate these cases. Patients were divided into two subgroups according to the cause of hydrocephalus; obstructive HCP, communicating HCP. Results: Mean time for follow up was 52 months. Mean age at surgery was 137days (7- 351days). The population included 31-females and 40-males, while10 infants were premature. Success rates were; 91.6%, 63.6% correspond to each sub-group with an overall success rate of 73.24%. Conclusion: ETV in infants is feasible, technically more demanding. Success rate justifies the procedure to be performed in such age group of patients. ETV can be used, attentively, in cases of hydrocephalus associated with MMC, morbidity and mortality does not differ from the general population.

Abstract
OBJECTIVE Hydrocephalus is the most common pediatric neurosurgical condition, with a high prevalence in low- and middle-income countries. Untreated, hydrocephalus leads to neurological disability or death. The epidemiology and outcomes of hydrocephalus treated by ventriculoperitoneal (VP) shunts in Sub-Saharan Africa are not well defined and vary by region. The aim of the present study was to examine the mortality and morbidity rates and predictors of mortality in children treated by VP shunt placement for hydrocephalus at Kamuzu Central Hospital in Lilongwe, Malawi. METHODS This is a prospective study of 100 consecutive children presenting with hydrocephalus who were treated with VP shunt placement from January 2015 to August 2017. Demographics, nutritional status, maternal characteristics, developmental delay, shunt complications, readmissions, and in-hospital and 3-month mortality data were collected. Multivariate logistic regression was used to identify predictors of death within 3 months of surgery. RESULTS Overall, 46% of participants were female, with an average age of 5.4 ± 3.7 months at the time of surgery. The majority of patients were term deliveries (87.8%) and were not malnourished (72.9%). Only 10.8% of children were diagnosed with meningitis before admission. In-hospital and 3-month mortality rates were 5.5% and 32.1%, respectively. The only significant association with mortality was maternal age, with older maternal age demonstrating decreased odds of 3-month mortality (OR 0.9, 95% CI 0.8-1.0, p = 0.045). CONCLUSIONS Surgical management of hydrocephalus with VP shunts portends a high mortality rate in Malawi. The association of younger maternal age with mortality is likely a proxy for social determinants, which appear to contribute as much to mortality as patient factors. VP shunting is inadequate as a sole surgical management of hydrocephalus in resource-limited settings.

Changes of third ventricle diameter (TVD) mirror changes of the entire ventricular system after initial therapy and during follow-up in pediatric hydrocephalus. Eur J Paediatr Neurol 2019; 23:571-580. [PMID: 31147106 DOI: 10.1016/j.ejpn.2019.05.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Revised: 03/31/2019] [Accepted: 05/09/2019] [Indexed: 11/20/2022]
Abstract
PURPOSE Regular measurement of ventricular size is important in children with hydrocephalus. After closure of the fontanelle this is currently addressed by repetitive cranial MRI or CT imaging, coming along with risks of anaesthesia or radiation. As the third ventricle is accessible via the temporal bone window using ultrasound, determination of its diameter might be an easy and radiation-free alternative to assess the ventricular system. An essential precondition is that changes of the third ventricle diameter (TVD) mirror changes of the whole ventricular system. This study compares changes of TVD with changes of ventricular indices before and after initial treatment of hydrocephalus and during the following evolution. METHODS MRT/CT images from 117 children with hydrocephalus were evaluated at time of diagnosis, after initial therapy and during follow-up with functional shunts. Measurements included axial TVD and three standard linear measures of the lateral ventricles (Evans Index - EI, fronto-occipital horn ratio - FOHR Index, and Cella Media Index - CMI). Furthermore, a correlation within subjects was calculated in 8 patients over the entire available follow-up. RESULTS Relative changes of TVD were significantly correlated to relative changes of all ventricular indices (r = 0.48, r = 0.68 and r = 0.701 for EI, FOHR and CMI, respectively, p < 0.01). The correlation within subjects was outstanding for EI (r = 0.988), FOHR (r = 0.99) and CMI (r = 0.99). CONCLUSION TVD showed a significant correlation with all three linear indices at the time of diagnosis and during follow-up changes independently of age, aetiology and ventricular width. TVD and its changes are therefore a reliable surrogate of changes in ventricular size in pediatric hydrocephalus undergoing treatment.

Abstract
PURPOSE OF REVIEW Two-thirds of the world's population lacks access to surgical care, many of them being children. This review provides an update on recent advances in global children's surgery. RECENT FINDINGS Surgery is being increasingly recognized as an essential component of global and child health. There is a greater focus on sustainable collaborations between high-income countries (HICs) and low-and-middle-income countries (HICs and LMICs). Recent work provides greater insight into the global disease burden, perioperative outcomes and effective context-specific solutions. Surgery has continued to be identified as a cost-effective intervention in LMICs. There have also been substantial advances in research and advocacy for a number of childhood surgical conditions. SUMMARY Substantial global disparities persist in the care of childhood surgical conditions. Recent work has provided greater visibility to the challenges and solutions for children's surgery in LMICs. Capacity-building and scale up of children's surgical care, more robust implementation research and ongoing advocacy are needed to increase access to children's surgical care worldwide.

Abstract
OBJECTIVE Hydrocephalus is one of the most common brain disorders, yet a reliable assessment of the global burden of disease is lacking. The authors sought a reliable estimate of the prevalence and annual incidence of hydrocephalus worldwide. METHODS The authors performed a systematic literature review and meta-analysis to estimate the incidence of congenital hydrocephalus by WHO region and World Bank income level using the MEDLINE/PubMed and Cochrane Database of Systematic Reviews databases. A global estimate of pediatric hydrocephalus was obtained by adding acquired forms of childhood hydrocephalus to the baseline congenital figures using neural tube defect (NTD) registry data and known proportions of posthemorrhagic and postinfectious cases. Adult forms of hydrocephalus were also examined qualitatively. RESULTS Seventy-eight articles were included from the systematic review, representative of all WHO regions and each income level. The pooled incidence of congenital hydrocephalus was highest in Africa and Latin America (145 and 316 per 100,000 births, respectively) and lowest in the United States/Canada (68 per 100,000 births) (p for interaction < 0.1). The incidence was higher in low- and middle-income countries (123 per 100,000 births; 95% CI 98-152 births) than in high-income countries (79 per 100,000 births; 95% CI 68-90 births) (p for interaction < 0.01). While likely representing an underestimate, this model predicts that each year, nearly 400,000 new cases of pediatric hydrocephalus will develop worldwide. The greatest burden of disease falls on the African, Latin American, and Southeast Asian regions, accounting for three-quarters of the total volume of new cases. The high crude birth rate, greater proportion of patients with postinfectious etiology, and higher incidence of NTDs all contribute to a case volume in low- and middle-income countries that outweighs that in high-income countries by more than 20-fold. Global estimates of adult and other forms of acquired hydrocephalus are lacking. CONCLUSIONS For the first time in a global model, the annual incidence of pediatric hydrocephalus is estimated. Low- and middle-income countries incur the greatest burden of disease, particularly those within the African and Latin American regions. Reliable incidence and burden figures for adult forms of hydrocephalus are absent in the literature and warrant specific investigation. A global effort to address hydrocephalus in regions with the greatest demand is imperative to reduce disease incidence, morbidity, mortality, and disparities of access to treatment.
