Abstract
PURPOSE To estimate the costs of the surgical treatment of pediatric hydrocephalus, specifically ventriculoperitoneal shunt (VPS) and endoscopic third ventriculostomy (ETV), for the Brazilian public health system (SUS). METHODS Retrospective cohort study of health records of patients < 14 years of age with a diagnosis of hydrocephalus who underwent VPS or ETV between September 2009 and June 2016, regularly followed up for 24 months. RESULTS Seventy-six medical records were included. The groups of children who underwent VPS and ETV consisted of 60 and 16 patients, respectively. Complications during 2 years of follow-up were identified in 56% of the children undergoing VPS and in 18% of those undergoing ETV (p = 0.0103). The initial cost of VPS was lower than that of ETV up to approximately 1 year of post-surgical follow-up. After that, VPS generated higher expenses for the SUS due to higher rates of late post-surgical complications and repeated readmissions. CONCLUSION Higher public expenditures were observed in the group of children undergoing VPS due to higher rates of infectious and mechanical complications requiring repeated hospitalizations and prosthesis replacements. Public policies must be tailored to offer the best treatment to children with hydrocephalus and to make judicious use of public resources without compromising the quality of treatment.

Abstract
The management of post-infective hydrocephalus in infants remains a challenging task for the pediatric neurosurgeon. The decision-making curve is often complex in that appropriate temporizing measures need to be implemented to properly clear any infection within the CSF before any decision can be made regarding a permanent solution. The etiology differs at varying stages of neonatal development, and the weight of the child, skin fragility, and relevant surgical treatment options are often important limiting factors. Deciding on the optimal treatment option involves assessing the etiology, age, and clinical and radiological features of the individual case and selecting the most appropriate surgical option.

Abstract
BACKGROUND A wide variety of intracranial cysts is known to occur in infants. If symptomatic, they require treatment; the ideal surgical treatment and indications of surgery are yet a matter of discussion. Traditional treatment is either by cystoperitoneal shunting, or microsurgical fenestration. Endoscopic treatment is an alternative procedure that avoids the invasiveness of open craniotomy and the complications caused by shunting. METHODS This article reviews the endoscopic treatment of intracranial cysts in infants. The author presents personal experience by reviewing the results of endoscopic treatment in different subgroups among his series of pediatric patients extending over 20 years. RESULTS Different types of intracranial cysts in infants were discussed and the role of endoscopy in the management of these patients was reviewed. The author also presented the results of endoscopic treatment of a personal series including 87 infants with intracranial cysts operated by the endoscopic procedure. CONCLUSIONS It has been recommended to use the endoscopic procedure in the treatment of intracranial cysts in infants, because it is effective, simple, minimally invasive, and associated with low morbidity and mortality rates. However, an important prerequisite is the presence of an area of contiguity with the subarachnoid cisterns and/or the ventricular system.

SAUDI JOURNAL OF MEDICINE & MEDICAL SCIENCES 2021; 9:261-266. [PMID: 34667474 PMCID: PMC8473994 DOI: 10.4103/sjmms.sjmms_85_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Revised: 06/05/2021] [Accepted: 08/02/2021] [Indexed: 11/16/2022]
Abstract
Background and importance: Infection following ventriculoperitoneal shunt (VPS) placement is a recognized complication, with variable incidence rates worldwide. Development of post-infectious multiloculated hydrocephalus (MLH) is likely if VPS infection is improperly managed, in turn affecting the prognosis. There is a lack of studies from Saudi Arabia regarding patients' functional outcome in relation to different variables. Objectives: To study the causative organisms, related variables and patient outcomes in MLH after VPS infection. Methods: This case series is a retrospective chart review of pediatric patients diagnosed with hydrocephalus from 2011 to 2019. Patients were included if they were aged <18 years, had confirmed cerebrospinal fluid/blood infection with radiological evidence of MLH, and were regularly followed-up. Functional status score was used to evaluate the outcomes. Results: A total of 150 patients underwent VPS insertion during the study period, of which 12 (8%) had postinfection MLH. The mean age at diagnosis and follow-up was 9 and 19 months, respectively. Ten patients developed MLH after their first VPS infection and one each developed MLH following the second and third VPS infections. Cerebrospinal fluid cultures mostly grew only single organisms (6/12), with Staphylococcus species being the most common. All patients underwent navigated endoscopic fenestration; nine patients required VPS placement and three required redo endoscopic fenestration surgery. All patients were developmentally delayed, with the majority (75%) having a functional status score of 6–10. Conclusion: Development of MLH after VPS infection is debilitating and requires prompt treatment. Although the overall functional outcome is poor, evolving neuroendoscopic techniques with tailored preoperative planning may play a role in reducing the adverse effect of shunt multiplicity, shunt infections and the higher failure rate among patients with complex 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.
