A two-institution pilot study on the psychological burden and distress of parents caring for children with shunted hydrocephalus.

Little is known about the emotional health of parents caring for children with shunted hydrocephalus. The aim of this pilot study was to find out whether parents caring for shunt-treated hydrocephalic children experience serious psychological problems and psychosocial distress and whether these problems are related to the sociodemographic background of the caregivers, the clinical characteristics of their children, and parents' illness-related concerns and perceived burden of their children's illness. This pilot study was performed in an outpatient setting at two German hospitals. The following questionnaires were handed out to parents of children with shunted hydrocephalus (< 21 years of age): the Patient Health Questionnaire (PHQ-9) for depression, the Generalized Anxiety Disorder Scale (GAD-7) for anxiety, the Distress Thermometer (DT) for psychosocial distress, the Hydrocephalus Concerns Questionnaire (HCQ) for assessment of parents' illness-related concerns, and the Hydrocephalus Outcome Questionnaire (HOQ) for assessment of perceived children's disease burden. Clinical data of the respective children were collected from electronic charts. Parents' demographic data were evaluated via questionnaires. Parents' psychological variables were correlated with demographic and clinical data and HCQ and HOQ scores. Regression analyses of HCQ and HOQ scores with psychological items were performed. Sixty-three parents were included in this study. Of these, 60% reported clinically relevant levels of either depression (11%), anxiety (10%), and/or psychosocial distress (57%). There were no associations between parental sociodemographic or children's clinical characteristics with parents' psychosocial well-being or psychosocial distress. Depression, anxiety, and DT scores were highly intercorrelated and significantly correlated with HCQ scores (r = 0.508, r = 0.516, r = 0.442; p < 0.01). Thereby, worries about shunt-related complications were the most reported concern in the HCQ. Depression and anxiety correlated with the scores of some HOQ subcategories. In preliminary regression analyses, higher illness-related concerns predicted occurrence of parents' anxiety. The authors' results support the notion that there is a need for psychosocial support for a proportion of parents who care for shunted hydrocephalic children. Perceived child symptom burden and parental illness concerns were identified as relevant correlates of parental psychological well-being. Thus, concerns specific to shunt-related problems could be a first starting point for the development of individual support measures.

Assessing the Quality of Life in Hydrocephalic Children: A Study from Tertiary Care Hospitals in Pakistan.

Hydrocephalus is a neurological disease with higher prevalence in the pediatric population, often managed by placing a shunt. This hollow tube drains excess cerebrospinal fluid from the brain to other body parts, resulting in several complications, including neurological and psychometric manifestations and a compromised quality of life (QoL). This study aimed to evaluate QoL in patients with hydrocephalus shunt placement within the pediatric population. This prospective observational study was conducted in two major Pakistani tertiary care hospitals. A total of 100 subjects were enrolled, of which 52 were found eligible. A validated questionnaire, Hydrocephalus Outcome Questionnaire, was used to evaluate patients' QoL. This study included pediatric patients with a mean age of 6.54 years and a standard deviation of ± 2.64. The male-to-female ratio was 27:25; 2% of patients had congenital or tumor-induced hydrocephalus, while cases of meningitis, encephalocele, and encephalitis accounted for 8, 4, and 2%, respectively. Myelomeningocele had the highest prevalence at 16%. The overall health scores range from 0.39 to 0.51. Social, cognitive, and physical health scores have mean values of 0.54, 0.50, and 0.48, respectively. The minimum physical health score is 0.17, indicating the most significant impact of hydrocephalus on physical function. This study highlights variations in hydrocephalus severity among pediatric patients, impacting their overall QoL, primarily physical and behavioral functioning. Worse health outcomes were associated with frequent seizures, prolonged hospital stays for diagnosis and treatment, shunt infections, increased number of shunt catheters, and longer travel distances to medical facilities.

Association of germinal matrix hemorrhage volume with neurodevelopment and hydrocephalus.

The objective of this study was to evaluate whether volumetric measurements on early cranial ultrasound (CUS) in high-grade germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) are associated with hydrocephalus and neurodevelopmental metrics. A retrospective case series analysis of infants with high-grade GMH-IVH admitted to the St. Louis Children's Hospital neonatal intensive care unit between 2007 and 2015 who underwent neurodevelopmental testing using the Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III) at 2 years of corrected age was performed. GMH volume, periventricular hemorrhagic infarction volume, and frontotemporal horn ratio were obtained from direct review of neonatal CUS studies. Univariate and multivariable regression models were used to evaluate the association between hemorrhage volumes and hydrocephalus requiring permanent CSF diversion with ventricular shunt or endoscopic third ventriculostomy with or without choroid plexus cauterization and composite Bayley-III cognitive, language, and motor scores. Forty-three infants (29 males, mean gestational age 25 weeks) met the inclusion criteria. The mean age at time of the CUS with the largest hemorrhage volume or first diagnosis of highest grade was 6.2 days. Nineteen patients underwent treatment for hydrocephalus with permanent CSF diversion. In multivariable analyses, larger GMH volume was associated with worse estimated Bayley-III cognitive (left-sided GMH volume: p = 0.048, total GMH volume: p = 0.023) and motor (left-sided GMH volume: p = 0.010; total GMH volume: p = 0.014) scores. Larger periventricular hemorrhagic infarction volume was associated with worse estimated Bayley-III motor scores (each side p < 0.04). Larger left-sided (OR 2.55, 95% CI 1.10-5.88; p = 0.028) and total (OR 1.35, 95% CI 1.01-1.79; p = 0.041) GMH volumes correlated with hydrocephalus. There was no relationship between early ventricular volume and hydrocephalus or neurodevelopmental outcomes. Location-specific hemorrhage volume on early CUS may be prognostic for neurodevelopmental and hydrocephalus outcomes in high-grade GMH-IVH.

Association of Glymphatic and White Matter Impairment With the Postoperative Outcome of Pediatric Hydrocephalus.

Assessment of postoperative outcomes on pediatric hydrocephalus is critical for adjusting treatment strategies. The aim of this work was to investigate the ability of MRI metrics to predict postoperative outcomes. A total of 55 children with hydrocephalus who underwent MRI and ventriculoperitoneal shunt surgery were prospectively enrolled. MRI was also performed at 6 months postoperatively in 33 of the 55 children. A total of 92 controls matched for age and sex were enrolled and divided into preoperative and postoperative control groups. We calculated the diffusion tensor imaging along the perivascular space (DTI-ALPS) index, Evans index, and diffusion tensor imaging metrics. The ability of various metrics to predict postoperative outcomes was assessed using receiver operating characteristic curve analysis. The DTI-ALPS index was significantly lower in patients with hydrocephalus than in controls. The abnormal DTI-ALPS index trended toward the normal range after surgery. Patients with lower preoperative DTI-ALPS index, lower fractional anisotropy (FA), and higher radial diffusivity in association fibers had less favorable short-term outcomes. Patients with worse long-term outcomes had lower postoperative DTI-ALPS index, higher postoperative Evans index, and lower FA and higher radial diffusivity in association fibers. Predictive performance was better when the DTI-ALPS index and FA in association fibers were used in combination than when either of these metrics was used alone. The DTI-ALPS index and FA in association fibers provided complementary information for prognostic assessment after the ventriculoperitoneal shunt surgery on pediatric hydrocephalus. A combination of DTI-ALPS index and FA would improve our ability to predict postoperative outcomes in these patients.

Predictors of Satisfactory Surgical Outcome in Idiopathic Normal Pressure Hydrocephalus (Review).

Idiopathic normal pressure hydrocephalus is a widespread neurodegenerative disease of the elderly. If not treated surgically early, it results in a severe decrease in quality of life and disability. According to current clinical Russian and foreign guidelines the candidates for CSF shunting procedures are selected based on the results of invasive tests, though treatment outcomes are not always optimal. At the same time, in the last decade there have been published a number of studies on promising noninvasive diagnosis and prognosis of the surgical treatment of idiopathic normal pressure hydrocephalus based on neuroimaging findings. The aim of the present systematic review is to demonstrate the most promising imaging predictors of satisfactory outcomes of CSF shunting procedures in patients with idiopathic normal pressure hydrocephalus based on published literature data.

Predictors and timing of hydrocephalus treatment in patients undergoing prenatal versus postnatal surgery for myelomeningocele.

Although hydrocephalus rates have decreased with intrauterine surgery for myelomeningocele (MMC), 40%-85% of children with MMC still go on to develop hydrocephalus. Prenatal ventricle size is known to be associated with later development of hydrocephalus; however, it is not known how prediction measures or timing of hydrocephalus treatment differ between pre- and postnatal surgery for MMC. The goal of this study was to determine anatomical, clinical, and radiological characteristics that are associated with the need for and timing of hydrocephalus treatment in patients with MMC. The authors retrospectively identified patients from Barnes Jewish Hospital or St. Louis Children's Hospital between 2016 and 2021 who were diagnosed with MMC prenatally and underwent either pre- or postnatal repair. Imaging, clinical, and demographic data were examined longitudinally between treatment groups and hydrocephalus outcomes. Fifty-eight patients were included (27 females, 46.6%), with a mean gestational age at birth of 36.8 weeks. Twenty-three patients (39.7%) underwent prenatal surgery. For the overall cohort, the ventricle size at prenatal ultrasound (HR 1.175, 95% CI 1.071-1.290), frontal-occipital horn ratio (FOHR) at birth > 0.50 (HR 3.603, 95% CI 1.488-8.720), and mean rate of change in head circumference (HC) in the first 90 days after birth (> 0.10 cm/day: HR 12.973, 95% CI 4.262-39.486) were identified as predictors of hydrocephalus treatment. The factors associated with hydrocephalus in the prenatal cohort were FOHR at birth > 0.50 (HR 27.828, 95% CI 2.980-259.846) and the rate of change in HC (> 0.10 cm/day: HR 39.414, 95% CI 2.035-763.262). The factors associated with hydrocephalus in the postnatal cohort were prenatal ventricle size (HR 1.126, 95% CI 1.017-1.246) and the mean rate of change in HC (> 0.10 cm/day: HR 24.202, 95% CI 5.119-114.431). FOHR (r = -0.499, p = 0.008) and birth HC (-0.409, p = 0.028) were correlated with time to hydrocephalus across both cohorts. For patients who underwent treatment for hydrocephalus, those in the prenatal surgery group were significantly more likely to develop hydrocephalus after 3 months than those treated with postnatal surgery, although the overall rate of hydrocephalus was significantly higher in the postnatal surgery group (p = 0.018). Clinical and imaging factors associated with hydrocephalus treatment differ between those receiving pre- versus postnatal MMC repair, and while the overall rate of hydrocephalus is lower, those undergoing prenatal repair are more likely to develop hydrocephalus after 3 months of age. This has implications for clinical follow-up timing for patients treated prenatally, who may live at a distance from the treatment site.

Ventricular CSF proteomic profiles and predictors of surgical treatment outcome in chronic hydrocephalus

BackgroundBy applying an unbiased proteomic approach, we aimed to search for cerebrospinal fluid (CSF) protein biomarkers distinguishing between obstructive and communicating hydrocephalus in order to improve appropriate surgical selection for endoscopic third ventriculostomy vs. shunt implants. Our second study purpose was to look for potential CSF biomarkers distinguishing between patients with adult chronic hydrocephalus benefitting from surgery (responders) vs. those who did not (non-responders).MethodsVentricular CSF samples were collected from 62 patients with communicating hydrocephalus and 28 patients with obstructive hydrocephalus. CSF was collected in relation to the patients’ surgical treatment. As a control group, CSF was collected from ten patients with unruptured aneurysm undergoing preventive surgery (vascular clipping).ResultsMass spectrometry-based proteomic analysis of the samples identified 1251 unique proteins. No proteins differed significantly between the communicating hydrocephalus group and the obstructive hydrocephalus group. Four proteins were found to be significantly less abundant in CSF from communicating hydrocephalus patients compared to control subjects. A PCA plot revealed similar proteomic CSF profiles of obstructive and communicating hydrocephalus and control samples. For obstructive hydrocephalus, ten proteins were found to predict responders from non-responders.ConclusionHere, we show that the proteomic profile of ventricular CSF from patients with hydrocephalus differs slightly from control subjects. Furthermore, we find ten predictors of response to surgical outcome (endoscopic third ventriculostomy or ventriculo-peritoneal shunt) in patients with obstructive hydrocephalus.

Neurococcidiomycosis in children with hydrocephalus: assessment of functional outcome, quality of life and survival in relation to neuroimaging findings.

Coccidioidal meningitis (CM) is an uncommon disease frequently misdiagnosed. Neuroimaging and mortality are not considered in detail in previous pediatric CM series. Our objective is to evaluate outcome of pediatric neurococcidiomycosis in relation to neuroimaging findings. We performed a prospective, observational, cross-sectional study in children with hydrocephalus and CM treated at Specialties Hospital in Torreon, Mexico (between 2015 and 2020). The outcome was evaluated by Hydrocephalus Outcome Questionnaire (HOQ) and themodified Rankin Scale (mRS). Follow-up was established at thefirst shunt surgery and survival since CM diagnosis confirmation. Neuroimaging was analyzed in relation to clinical data, outcome and survival. Kaplan-Meier analysis was performed with IBM-SPSS-25. Ten pediatric cases with CM and hydrocephalus were reported. Aged 6-228months, 60% were female. Mean number of surgeries was 4.3 SD ± 3 (range 1-15). Asymmetric hydrocephalus was the most common neuroimaging finding (70%), followed by cerebral vasculitis (20%) and isolated fourth ventricle (IFV) (20%). The mean HOQ overall score was 0.338 SD ± 0.35. A minimum follow-up of 18months was reported. Mean survival was 13.9 SD ± 6.15months (range 3-24). Poor survival was correlated with asymmetric hydrocephalus (p = 0.335), cerebral vasculitis (p = 0.176), IFV (p < 0.001), bacterial superinfection (p = 0.017), lower mRSscores at hospitaldischarge (p = 0.017) and duringfollow-up (p = 0.004). The mortality rate was 20%. We report the largest series in Latin America of pediatric CM and hydrocephalus. Asymmetric hydrocephalus, IFV and cerebral vasculitis are complications that increase mortality and must be early diagnosed for atimely surgical and medical treatment. HOQ andmRS could be alternative scales to evaluate outcomein these patients. After a long follow-up (18months), survival remained poor after diagnosis confirmation in our series.

Risk and prognostic factors in patients with congenital encephalocele

Background and objectiveEncephaloceles are considered to be a spectrum of neural tube defects with a herniation of the brain and the meninges through a bony skull defect to the exterior.MethodsThis retrospective and prospective study was carried out on 30 patients with congenital encephaloceles either vault or basal. The risk factors and the prognostic factors were assessed.ResultsThere was a statistically significant association between the content of the sac, outcome and seizures. There was a presence of neural tissue associated with worse outcome and seizures. There was a statistically significant association between the size of the sac and outcome with seizure. There was a statistically insignificant association between site of defect and parent consanguinity, folic acid intake, drug history, seizures, outcome, gender, family history and a statistically significant association between the site of the sac and hydrocephalus. There was a statistically significant association between the outcome and presence of Hydrocephalus, microcephaly and seizures.ConclusionsThere was statistically significant association between the worst outcome and presence of hydrocephalus, microcephaly and seizures, and there is correlation between site of the defect in occipitocervical region and development of hydrocephalus.

Perioperative external ventricular drainage vs. no-EVD strategy in pediatric posterior fossa tumors—pilot study results

IntroductionPediatric brain tumors of the posterior fossa often present with occlusive hydrocephalus. Endoscopic third ventriculostomy (ETV) or ventriculoperitoneal shunting (VPS) has been established for definite hydrocephalus treatment. The aim of the study was to analyze the impact and safety of perioperative temporary external ventricular CSF drainage (EVD) placement on postoperative hydrocephalus outcome compared to a no-EVD strategy.Patients and methodsIn a prospective database, 36 posterior fossa tumor patients of 2–18 years were included with a follow-up of 1 year. Fifty-eight percent presented with preoperative hydrocephalus. Patients were assigned to non-hydrocephalus group: group I (n = 15) and to preoperative hydrocephalus, group IIa with EVD placement (n = 9), and group IIb without EVD (n = 12).ResultsMedian age of patients was 8.1 years (range 3.17 to 16.58 years). One-third of 21 hydrocephalus patients required ETV or VPS (n = 7). Occurrence of de novo hydrocephalus in group I after surgery was not observed in our cohort. Age and histology were no confounding factor for EVD placement between group IIa and IIb (p = 0.34). The use of EVD did not result in better control of hydrocephalus compared to no-EVD patients considering pre- and postoperative MRI ventricular indices (p = 0.4). Perioperative placement of an EVD resulted in a threefold risk for subsequent VPS or ETV (group IIa 55.5% vs group IIb 16.6%): relative risk for EVD patients compared to no-EVD patients with hydrocephalus was 3.3 (CI = 1.06–13.43, p = 0.09).ConclusionPerioperative EVD placement appears to harbor a threefold relative risk of requiring subsequent permanent CSF diversion in children above 2 years. EVD was not more effective to control ventricular enlargement compared to tumor removal alone. The no-EVD strategy was safe and did not result in postoperative complications. Thus, to evaluate potential adverse effects on hydrocephalus outcome by EVD placement, a prospective study is warranted to falsify the results.

The effect of shunt removal on the quality of life in patients with congenital hydrocephalus.

Although there have been reports investigating the quality of life of patients who underwent ventriculoperitoneal shunting or endoscopic third ventriculostomy (ETV) for congenital hydrocephalus, there have been no studies of the quality of life of patients after ventriculoperitoneal shunt (VPS) removal. In the present study, a survey of pediatric and congenital hydrocephalus patients was conducted to compare the quality of life of patients with a remaining VPS with that of patients who had the shunt removed. Between February 2020 and November 2021, an outpatient survey was administered to patients 8years of age and older who had undergone VPS due to a diagnosis of congenital hydrocephalus. The Hydrocephalus Outcome Questionnaire (HOQ) was used to assess the quality of life for this study. The HOQ scores (overall health score, physical health score, cognitive health score, and social-emotional health score) were compared among three groups: a VPS-remaining group, VPS-removed with endoscopic third ventriculostomy (ETV) group, and VPS-removed without ETV group. The total number of patients who underwent VPS for hydrocephalus was 71, with 47 in the VPS-remaining group, 14 in the shunt-removed with ETV group, and 10 in the shunt-removed without ETV group. The HOQ overall health score was 0.68 for the VPS-remaining group, 0.74 for the shunt-removed with ETV group, and 0.74 for the shunt-removed without ETV. There were no significant differences between the VPS-remaining group and the VPS-removed with or without ETV groups (p = 0.3255, 0.4178, respectively). There was no significant difference in the quality of life between patients with a remaining VPS and those who had their VPS removed with or without ETV.

Outcomes of Tuberculous Meningitis Patients with or without Hydrocephalus from a Tertiary Hospital in West Java, Indonesia

Background: Tuberculous meningitis (TBM) is a severe form of extrapulmonary tuberculosis. One of the most common complications of TBM is hydrocephalus, with a higher risk of mortality. This study aimed to evaluate the outcome among TBM patients with or without hydrocephalus.Methods: This study was a retrospective cross-sectional comparative analytical study. A total sampling was employed based on the number of traceable resumes of TBM patients treated at the Department of Neurology Dr. Hasan Sadikin General Hospital, Bandung, Indonesia in 2018. Results: Of the 127 data of TBM patients, 55 (43.3%) had hydrocephalus, and 72 (56.7%) did not. The median age of TBM patients with and without hydrocephalus was 34 years (IQR 26–45) and 35 years (IQR 24–44), respectively. Decreased consciousness dominated the clinical symptoms for 94.5% in the hydrocephalus group and 84.7% in the non-hydrocephalus group. Hospital-acquired pneumonia occurred mainly in the hydrocephalus group (29.1%), whereas urinary tract infections mainly occurred in without hydrocephalus group (18%). There was a significant difference between the outcome of hydrocephalus and non-hydrocephalus (p=0.005). Mortality was higher in patients with hydrocephalus compared to those without hydrocephalus.Conclusions: The outcome of TBM patients with hydrocephalus is worse than those without hydrocephalus, as reflected by a higher grade of TBM, higher mortality rate, and lower good recovery upon treatment administration. Therefore, prompt diagnosis and treatment are needed to improve the outcome and survival among TBM patients with hydrocephalus.

Medico-socio-economic perspective of congenital hydrocephalus patients treatment in dr. Soetomo Academic General hospital, Surabaya, Indonesia

Background: Hydrocephalus is a brain disease that requires prompt treatment. The outcome of hydrocephalus is dependent on early detection and treatment. This study was conducted to analyze the medico-socio-economic perspective on the delayed treatment of hydrocephalus patients, which aimed to advance the practice of neurosurgery in the socio-neurosurgery field, including both preventive and therapeutic aspects. Method: This was an observational analysis study. The study subjects were all patients with congenital hydrocephalus treated in dr. Soetomo Academic General Hospital between January 2017 and December 2019. The study was carried out on January 2017 to December 2019 at the Inpatient Surgery ward, dr Soetomo Academic General Hospital, neurosurgery outpatient unit, and home visits. Research data consists of both primary and medical record data. Data on patient characteristics were obtained through direct interviews with the sample using prepared questionnaires, medical record data, and radiological data of both patients examined at dr. Soetomo Academic General Hospital and other health services. Bivariate correlation analysis was performed to assess the effect of each risk factor on the incidence of delay in treatment, and multivariate logistic regression analysis was performed to assess the magnitude of the effect of risk factors. Result: The number of cases was 101 subjects. A total of 101 patients included as research samples were congenital hydrocephalus patients who received the first treatment at dr. Soetomo Academic General Hospital from January 2017 to December 2019. Up to 50 individuals (49.5%) were delayed in treatment. The data analysis with Chi-square did not reveal a statistically significant correlation between delay in treatment and level of parent's education (p=0.0951), delay in treatment and economic status ((p=0.4955). Delays in the treatment of congenital hydrocephalus were statistically significant and correlated with Posyandu's role (p=0.0012), health insurance ownership (p=0.0001), family support (p=0.0130), and professional medical decisions (p=0.0001). Health insurance ownership has the smallest p-value (0.000) and largest wald (16.545) in the multivariate logistic regression analysis calculation using the enter method. The insurance ownership variable has the most significant and largest partial influence on the delay in treating congenital hydrocephalus. Conclusion: There were 101 patients included, and up to 50 individuals (49.5%) were delayed in treatment. Parents' education level and socioeconomic status were not associated with delayed treatment of congenital hydrocephalus. Delays in managing congenital hydrocephalus were influenced by Posyandu's role, health insurance ownership, family support, and professional medical decisions.

Children hydrocephalus in Togo: etiologies, treatment, and outcomes.

Hydrocephalus is frequent in sub-Saharan African countries. The postinfectious hydrocephalus tends to decrease. The objective of this study was to identify the etiologies and outcomes of hydrocephalus. This was a retrospective study of hydrocephalus cases (0-15 years old) treated in the neurosurgery unit of the Sylvanus Olympio Hospital in Lomé over 10 years (2012-2021). At 1 year, the evolution distinguished in two categories: (1) Good psychomotor development: no delay in the acquisition of walking, language, and school. (2) Psychomotor delay: delay in the acquisition of walking, language, and school. We reported 305 children treated for hydrocephalus representing 1.8% of all neurosurgery unit patients and 34.2% of pediatric pathologies. There was a male predominance (60.6%). We noted second degree consanguinity in 8.5%. The positive maternal serologies were HIV (12.4%), syphilis (8.2%), and toxoplasmosis (2.6%). A malaria episode had been treated during the first trimester in 36.7% of the mothers. The main clinical sign of hydrocephalus was 91.5% of Macrocephalus. Congenital Malformafions were the most common etiologies of hydrocephalus (68.5%). Ventriculoperitoneal shunt was the main surgical method used and 16 deaths were recorded. The medium-term evolution (1 year) was evaluated in 36.1% and noted 61.8% of psychomotor retardation. This study confirms the trend of the predominance of congenital causes of hydrocephalus in Africa, even if maternal infections can be involved in the development of some of them. The morbimortality of this pathology remains important, especially concerning neurocognitive outcomes.

New insights into the management of post-hemorrhagic hydrocephalus

During the last decade, an increasing number of studies have been conducted to improve the outcome of post-hemorrhagic hydrocephalus (PHH), a complication of severe intraventricular hemorrhage (IVH) in preterm infants. Two randomized controlled trials have shown that treatment should be initiated prior to the onset of clinical symptoms. Ventricular access devices and subgaleal shunts are used as temporary neurosurgical interventions whereas ventriculoperitoneal shunts are performed for infants with progressive hydrocephalus. Recently, techniques such as neuro-endoscopic lavage have also been introduced to eliminate toxic blood products and debris from the cerebral ventricles and have shown promise in early clinical studies. The objective of this review is to provide an update on management of PHVD and PHH in the preterm infant.

Impact of ventricle size on neuropsychological outcomes in treated pediatric hydrocephalus: an HCRN prospective cohort study.

In pediatric hydrocephalus, shunts tend to result in smaller postoperative ventricles compared with those following an endoscopic third ventriculostomy (ETV). The impact of the final treated ventricle size on neuropsychological and quality-of-life outcomes is currently undetermined. Therefore, the authors sought to ascertain whether treated ventricle size is associated with neurocognitive and academic outcomes postoperatively. This prospective cohort study included children aged 5 years and older at the first diagnosis of hydrocephalus at 8 Hydrocephalus Clinical Research Network sites from 2011 to 2015. The treated ventricle size, as measured by the frontal and occipital horn ratio (FOR), was compared with 25 neuropsychological tests 6 months postoperatively after adjusting for age, hydrocephalus etiology, and treatment type (ETV vs shunt). Pre- and posttreatment grade point average (GPA), quality-of-life measures (Hydrocephalus Outcome Questionnaire [HOQ]), and a truncated preoperative neuropsychological battery were also compared with the FOR. Overall, 60 children were included with a mean age of 10.8 years; 17% had ≥ 1 comorbidity. Etiologies for hydrocephalus were midbrain lesions (37%), aqueductal stenosis (22%), posterior fossa tumors (13%), and supratentorial tumors (12%). ETV (78%) was more commonly used than shunting (22%). Of the 25 neuropsychological tests, including full-scale IQ (q = 0.77), 23 tests showed no univariable association with postoperative ventricle size. Verbal learning delayed recall (p = 0.006, q = 0.118) and visual spatial judgment (p = 0.006, q = 0.118) were negatively associated with larger ventricles and remained significant after multivariate adjustment for age, etiology, and procedure type. However, neither delayed verbal learning (p = 0.40) nor visual spatial judgment (p = 0.22) was associated with ventricle size change with surgery. No associations were found between postoperative ventricle size and either GPA or the HOQ. Minimal associations were found between the treated ventricle size and neuropsychological, academic, or quality-of-life outcomes for pediatric patients in this comprehensive, multicenter study that encompassed heterogeneous hydrocephalus etiologies.

Improving Infant Hydrocephalus Outcomes in Uganda: A Longitudinal Prospective Study Protocol for Predicting Developmental Outcomes and Identifying Patients at Risk for Early Treatment Failure after ETV/CPC.

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.
