RESUMO

The objective of this pilot study was to assess the reliability of superb microvascular ultrasound (SMI) for the measurement of the cerebrospinal fluid (CSF) flow within VPS systems as an indirect sign for shunt dysfunction. Asymptomatic hydrocephalus patients, with a VPS system implanted between 2017 and 2021, were prospectively enrolled in the study. Using SMI, the CSF flow within the proximal and distal catheters were analysed. Before and after pumping the shunt reservoir, intraabdominal free fluid, optical nerve sheath diameter (ONSD), and papilla diameter (PD) were evaluated and correlated with the amount of valve activation. Nineteen patients were included. A flow was detectable in 100% (N = 19) patients in the proximal and in 89.5% (N = 17) in the distal catheter. The distal catheter tip was detectable in 27.7% (N = 5) patients. Free intraabdominal fluid was initially detected in 21.4% (N = 4) patients and in 57.9% (N = 11) at the end of the examination (P = 0.049). ONSD was significantly lower after pump activation (4.4 ± 0.9 mm versus 4.1 ± 0.8 mm, P = 0.049). Both peak velocity and flow volume per second were higher in proximal compared to distal catheters (32.2 ± 45.2 versus 5.6 ± 3.7 cm/sec, P = 0.015; 16.6 ± 9.5 ml/sec versus 5.1 ± 4.0 ml/sec, P = 0.001, respectively). No correlation was found between the number of pump activations and the changes in ONSD (P = 0.975) or PD (P = 0.820). SMI appears to be a very promising non-invasive diagnostic tool to assess CSF flow within the VPS systems and therefore affirm their function. Furthermore, appearance of free intraperitoneal fluid followed by repeated compression of a shunt reservoir indicates an intact functioning shunt system.

RESUMO

BACKGROUND: Tuberculosis (TB) remains a significant global health concern, with extrapulmonary manifestations, including central nervous system involvement, posing substantial morbidity and mortality. While medical treatment with anti-TB drugs is the mainstay of therapy, certain TB-related cerebral complications, such as hydrocephalus, abscesses, and large symptomatic tuberculomas, may require surgical intervention. This study aimed to evaluate the outcomes of surgical management in patients with TB-related cerebral disorders. METHODS: A retrospective analysis was conducted on 24 patients who underwent surgical intervention for TB-related cerebral disorders, including tuberculomas, hydrocephalus, and abscesses, at a tertiary care center between 2005 and December 2020. Demographic data, clinical presentations, radiological findings, surgical techniques, and treatment outcomes were analyzed. RESULTS: The study cohort had a mean age of 35.8 ± 13.6 years, and the majority (62.5%) were male. Underlying immunodeficiency, primarily HIV infection, was present in 75% of the patients. The most common presenting symptoms were headache (83.3%), focal neurological deficits (75%), and altered mental status (54.2%). Radiological findings revealed 13 (54.2%) tuberculomas, 8 (33.3%) instances of hydrocephalus, and 3 (12.5%) abscesses. VP shunt inserted in 8 (33.3%) cases. Microscopic craniotomy performed in 7 (29.16%) cases. Aspiration through burr hole was done in 3 (12.5%) cases and stereotactic biopsy was performed in 6 (25%) cases. After 12 months of follow-up, favorable outcome achieved in 18 cases (75%) and the mortality occurred in 2 patients (8.3%). Surgical interventions included lesion resection (n = 10), stereotactic biopsy (n = 7), and ventriculoperitoneal (VP) shunt placement (n = 7). At 12-month follow-up, 18 (75%) patients had a favorable outcome, defined as clinical improvement or stabilization. Unfavorable outcomes were observed in 6 (25%) patients, including 2 deaths. CONCLUSION: Surgical management, in conjunction with appropriate anti-TB medical therapy, may be a valuable component of the comprehensive treatment approach for select patients with TB-related cerebral disorders. The favorable outcome rate observed in this study suggests that timely and tailored surgical intervention can contribute to improved patient outcomes. However, larger, prospective, multicenter studies are needed to further elucidate the role and long-term efficacy of surgical management in this patient population.

RESUMO

BACKGROUND: When a pregnant mother finds out she has a fetus with a congenital defect, the parents feel profound worry, anxiety, and melancholy. Anomalies can happen in singleton or twin pregnancies, though they are more common in twin pregnancies. In twins, several congenital defects are typically discordant. We present a rare case of concordant fatal anomaly in twin pregnancy in a 22-year-old African patient primigravida mother from Western Ethiopia who presented for routine antenatal care. An obstetric ultrasound scan showed anencephaly, meningomyelocele, and severe ventriculomegaly. After receiving the counseling, the patient was admitted to the ward, and the pregnancy was terminated with the medical option. Following a successful in-patient stay, she was given folic acid supplements and instructed to get preconception counseling before getting pregnant again. CONCLUSION: The case demonstrates the importance of early obstetric ultrasound examination and detailed anatomic scanning, in twin pregnancies in particular. This case also calls for routine preconceptional care.

RESUMO

Meta-analysis and systematic review. To understand the role of endoscopic third ventriculostomy (ETV) for the treatment of concurrent Chiari Malformation Type I (CMI) and hydrocephalus in adults. A literature search on PubMed and Medline with MeSH terms relating to ETV and CMI identified 155 articles between 1988 and 2024. After excluding pediatric cases and other CNS pathologies with associated CMI, 11 articles met inclusion criteria. The Newcastle-Ottawa Scale was identified to assess heterogeneity and risk of bias among the 11 studies analyzed in this systematic-review and meta-analyses compared pre- and post-operative outcomes to examine the use of ETV as a treatment modality for CMI with hydrocephalus. From the 11 included studies, 35 cases of concurrent CMI and hydrocephalus treated with ETV were identified. ETV provided a pooled rate of symptom resolution or improvement of 66%. Additionally, meta-analysis discovered the following pooled rates: a reduction of tonsillar descent in 94% of patients, decreased ventriculomegaly in 94%, and ETV patency in 99%. Syringomyelia, nausea, papilledema and cerebellar dysfunction did not have sufficient numbers for meaningful statistical analyses. However, in each of these categories, more than 85% of the symptoms or radiographic findings improved. This review summarizes the safety and efficacy of ETV for the concurrent management of acquired CMI with hydrocephalus. Specifically, ETV improves radiological outcomes of both ventriculomegaly and tonsillar descent as well as the most prevalent neurological symptom, headaches.

RESUMO

Shunt infection is one of the most common complications of conventional hydrocephalus treatment. The route of invasion of a pathogen can modify the immune response of the CNS. The aim of the study is to analyze the immune response to shunt infection caused by S. epidermidis in children with hydrocephalus. The immune response to the pathogen will be analyzed on the basis of, inter alia, simple laboratory test results, such as changes in the pattern of white blood cells, including neutrophils, monocytes, and lymphocytes. The entire study analyzes changes in general parameters of the cerebrospinal fluid (pleocytosis, protein level, glucose level) and in levels of selected interleukins (IL-6, CXCL8 / IL-8, CCL3 / MIP-1a) in the cerebrospinal fluid. The clinical material analyzed in the study was collected in 2010-2014. The study group consisted of 30 patients, who were admitted to the hospital due to their first-ever episode of valve dysfunction caused by S. epidermidis infection. The control group consisted of 30 children who also suffered from congenital hydrocephalus but had not been operated on before. The most pronounced response to CSF infection in the study group was a significant increase in the counts of all investigated WBC lines in the samples collected immediately after the patients' admission to the ward. The earliest aberration of the CSF was a significant increase in protein level. An infection of a ventriculoperitoneal shunt caused by S. epidermidis evokes a very early peripheral blood response. In children affected by a ventriculoperitoneal valve infection, the humoral immune response detected in the cerebrospinal fluid precedes the increase in the level of pleocytosis. The highest level of cytokines in the cerebrospinal fluid is achieved when the pathogens are cleared. Phagocytes, and, in particular, monocytes, play an important role in the normalization of the cerebrospinal fluid parameters after the elimination of S. epidermidis. The local immune response of the central nervous system plays an important role in extinguishment of the inflammatory process.

RESUMO

Shunt dependent hydrocephalus (SDHC) is a common sequel after aneurysmal subarachnoid hemorrhage (aSAH) and factors contributing to the development of SDHC remain obscure. The aim of this study was to identify predictors of SDHC following aSAH. We conducted a systematic review based on the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. We searched electronic databases including Pubmed, Embase, and Cochrane databases from 1980 through August 2019 for studies on the risk factors of SDHC after aSAH. Inclusion criteria were: (1) SAH and hydrocephalus confirmed by CT or magnetic resonance imaging findings; (2) the odds ratios (ORs) or the relative risk (RR) with 95% confidence interval (95%CI; or crude data that allowed their calculation) were reported; and (3) languages were restricted to English and Chinese. Two independent authors collected the data including study design, characteristics of patients and potential risk factors. Random-effects models were used to estimate weighted mean differences (WMD), relative risks (RR) with corresponding 95% confidence intervals (CI). For analysis with significant heterogeneity, subgroup analyses stratified by study design and geographic area were performed. In all, 37 cohort studies met inclusion criteria. Several factors were associated with SDHC. Infection, acute hydrocephalus, placement of external ventricular drainage, older age, higher Hunt and Hess grade, intraventricular hemorrhage, rebleeding, and mechanical ventilation were associated with greater 2-fold increased risk of SDHC. Vasospasm, female gender, high Fisher grade, preexisting hypertension, aneurysm in posterior location and intracerebral hemorrhage were associated with less than 2-fold increased risk. Treatment modality and diabetes mellitus were not associated with SDHC. SDHC is a multi-factorial disease that is associated with patient and treatment factors. Acknowledgement of these potential factors could help prevent SDHC.

RESUMO

BACKGROUND: Angiostrongyliasis cantonensis is a severe yet rare parasitic infection caused by the larvae of Angiostrongylus cantonensis. The primary characteristic feature of this foodborne illness in humans is eosinophilic meningitis. Recently, there has been a gradual increase in reported cases globally. Due to the lack of typical clinical symptoms, signs, and specific laboratory tests, early diagnosis of this disease poses significant challenges. Failure to diagnose and treat this condition promptly can result in fatalities. METHODS: We present the case of a 13-year-old male patient who initially presented with fever and headache. The patient was preliminarily diagnosed with bacterial meningitis and received treatment with antibacterial drugs. However, the patient's condition worsened, and he developed progressive consciousness disturbances. Eventually, metagenomic next-generation sequencing (mNGS) testing of cerebrospinal fluid samples indicated Angiostrongylus cantonensis infection. Following treatment with albendazole and prednisone, the patient made a full recovery. We include this case report as part of a literature review to emphasize the potential applications of mNGS in the early diagnosis of Angiostrongyliasis cantonensis. CONCLUSION: mNGS technology plays a crucial role in the diagnosis of angiostrongyliasis cantonensis. As this technology continues to evolve and be applied, we believe it will play an increasingly important role in diagnosing, treating, and monitoring angiostrongyliasis cantonensis.

RESUMO

Hydrocephalus is a commonly encountered pathology in the neurosurgical practice. Since the first permanent ventriculo-subarachnoid-subgaleal shunt described by Mikulicz in 1893, there were multiple attempts to find solutions for draining the excess production/less reabsorption of the cerebrospinal fluid (CSF) from the brain. Nowadays, the most common technique is the ventriculoperitoneal shunt (VPS), whereas the ventriculoatrial shunt (VAS) is applied only in some rare conditions. To date there are still no specific guidelines or strong evidence in literature that guide the surgeon in the choice between the two methods, and the decision usually relies on the confidence and expertise of the surgeon. Considering the lack of established recommendations, this systematic review and meta-analysis aims to evaluate the effectiveness and safety of these two shunting techniques. This systematic review was conducted following the PRISMA protocol (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). No chronological limits of study publications were included. Prospective and retrospective clinical studies, and reports of case series with at least five patients per group and reporting data on comparison between VAS and VPS techniques were eligible for inclusion. Nine studies reporting 3197 patients meeting the inclusion and exclusion criteria were identified and included in the quantitative synthesis. The risk of shunt dysfunction/obstruction was significantly lower in the VAS group [odds ratio (OR) 0.49, 95%-CI 0.34-0.70, I2 0%]. The risk of infection was not significantly different between the two groups (OR 1.02, 95%-CI 0.59-1.74, I2 0%). The risk of revision was not significantly different between the two groups; however, the heterogeneity between the studies was significant (OR 0.73, 95%-CI 0.36-1.49, I2 91%). Additionally, the risk of death was not significantly different between the two groups; however, the heterogeneity between the studies was high (OR 1.93, 95%-CI 0.81-4.62, I2 64%). VAS remains a safe surgical alternative for hydrocephalus. The results of this study highlight a lower risk of shunt dysfunction/obstruction variable in the VAS group, with no significant statistical differences regarding the occurrence of at least one infection-related complication. In consequence, the choice between these two techniques must be tailored to the specific characteristics of the patient.Protocol Registration: The review protocol was registered and published in Prospective Register of Systematic Reviews (PROSPERO) ( www.crd.york.ac.uk/PROSPERO ) website with registration number: CRD42023479365.

RESUMO

Ciliary beat and intraflagellar transport depend on dynein and kinesin motors. The kinesin-9 family members Kif6 and Kif9 are implicated in motile cilia motilities across protists and mammals. How they function and whether they act redundantly, however, remain unclear. Here, we show that Kif6 and Kif9 play distinct roles in mammals. Kif6 forms puncta that move bidirectionally along axonemes, whereas Kif9 appears to oscillate regionally on the ciliary central apparatus. Consistently, only Kif6 displays microtubule-based motor activity in vitro, and its ciliary localization requires its ATPase activity. Kif6 deficiency in mice disrupts coordinated ciliary beat across ependymal tissues and impairs cerebrospinal fluid flow, resulting in severe hydrocephalus and high mortality. Kif9 deficiency causes mild hydrocephalus without obviously affecting the ciliary beat or the lifespan. Kif6-/- and Kif9-/- males are infertile but exhibit oligozoospermia with poor sperm motility and defective forward motion of sperms, respectively. These results suggest Kif6 as a motor for cargo transport and Kif9 as a central apparatus regulator.

RESUMO

Proteus mirabilis is a very common gram-negative facultative anaerobe seen in urinary tract infections. This rod-shaped bacterium tends to cause urolithiasis via its ability to alkalinize the urine. However, in some cases, this bacterium has been shown to cause bacteremia as well as other complicated infections. Here we would like to present a rare case of Proteus mirabilis that has invaded the brain in a patient that has a ventriculoperitoneal (VP) shunt placed due to coccidioidal meningitis causing hydrocephalus. We would also like to discuss the importance of the monitoring of VP shunt and discuss their likelihood of infections and the medical as well as surgical management.

RESUMO

BACKGROUND: Ventriculoperitoneal (VP) shunts are commonly used for managing hydrocephalus, with mechanical dysfunction being the most common cause of complications that require revision. A VP shunt placed using a real-time three-dimensional (3D) robotic C-arm navigation system may have better outcomes and fewer complications. METHODS: In this technical note, we introduced the workflow of the use of the real-time 3D robotic C-arm navigation system for ventriculoperitoneal shunting. CONCLUSION: The real-time 3D robotic C-arm can provide a more precise approach to the target. Furthermore, this technique may lower the risk of complications and increase the success rate of shunt placements.

RESUMO

OBJECTIVE: The pediatric neurosurgical community has increasingly recognized the importance of healthcare transition, the process of moving a patient from a pediatric to an adult model of care. However, surveys of pediatric neurosurgeons have revealed that few institutions have formal transition programs. Here, the authors share their preliminary experience with the development of a formal transition pilot program for patients with spina bifida and/or hydrocephalus. METHODS: Patients 18 years of age or older with a diagnosis of spina bifida and/or hydrocephalus who were followed by a pediatric neurosurgeon at Connecticut Children's from January 2017 to December 2023 and were recommended to transition to an adult neurosurgeon were retrospectively reviewed. Patients in the informal transition program (ITP) cohort (i.e., the recommendation to transition was made before the formal transition program [FTP] was developed in early 2020) were compared with those in the FTP cohort. RESULTS: Twenty-two patients met inclusion criteria with 7 (31.8%) in the ITP cohort and 15 (68.2%) in the FTP cohort. The median age at the time of the recommendation to transition was similar in both ITP and FTP cohorts (24 [IQR 20-35] years vs 25 [IQR 24-27] years, respectively). Four (57.1%) patients in the ITP cohort had a confirmed visit with an adult neurosurgeon, compared with 13 (86.7%) patients in the FTP cohort (p = 0.274). One patient in the ITP cohort with a failed transition returned to pediatric neurosurgical care, and 1 patient in the FTP cohort required a shunt revision by an adult neurosurgeon within 1 year of the recommendation to transition. CONCLUSIONS: Healthcare transition is recognized as a priority within pediatric neurosurgery, but structured, formal transition programs remain underdeveloped. The authors' preliminary experience with a pilot transition program demonstrated that patients who underwent a formal transition were more likely to successfully establish care with an adult neurosurgeon and trended toward less resource utilization.

RESUMO

The complications anticipated in the postoperative period after surgical resection of lateral ventricular neoplasms (LVN) are hemorrhage, hydrocephalus. At the N.N. Burdenko Neurosurgery Center, 48 patients with LVN underwent surgical resection. We focused on the correlation between approaches to the ventricular system on one hand and the extent of resection and incidence of complications on the other based on anatomical and perfusion characteristics estimated via preoperative magnetic resonance imaging (MRI) with arterial spin labeling perfusion. By eliminating the surgical approach as a potential risk factor, we were able to demonstrate the correlation between the frequency of postoperative hemorrhage, the Evans index value, patient's gender, tumor blood flow (nTBF) and the location of the mass in the anterior horn of the lateral ventricle. The risk of hemorrhage depends on the patient's gender, presence of hydrocephalus, location of the mass and tumor blood flow values. The risk increases along with increase in Evance index and nTBF values.
