El KheshinAbstractPurposeThe aim is to assess the usefulness of cine phase-contrast MRI for evaluation of patency of endoscopic third ventriculostomy operation and correlation with clinical state postoperatively.Material &methodsProspective study performed upon 20 patients who underwent ETV operation, concerned on obstructive hydrocephalus (age range, 4–63 years; 11 male &9 Female). Cine PC-MRI CSF flowmetry technique was applied for qualitative and quantitative assessment of CSF flow dynamics through ETV stoma to assess its patency.ResultsThe patency of ETV stoma was evaluated according to overall flow amplitude (OFA) as it was the most effective variable to predict the response to surgery, we found that when OFA value is ≥75 μL, the sensitivity and specificity of our technique to determine patient improvement were 71.4% and 76.9%, respectively.According to OFA, we classified the state of ETV stoma into three subcategories: patent stoma with adequate flow; OFA value ≥75 μL (10 patients), patent stoma with low flow; OFA value from 25 up to

Conclusion: We present the application of a continuum robot with FTL motion to perform a combined ETV/ETB procedure. The validation study using human subject data indicated that the accuracy of FTL motion is relatively high. The study indicated that FTL motion may be useful tool for combined ETV and ETB.

Publication date: Available online 18 January 2020Source: IDCasesAuthor(s): Shawn Gerstein, Pranisha Gautam-Goyal, Sameer GoyalAbstractListeria monocytogenes is a gram-positive bacillus known to cause various human infections including central nervous system infections. The most common central nervous system manifestations are meningitis and rhomboencephalitis, however rare complications including hydrocephalus and intracerebral hemorrhage can occur and are associated with increased mortality and incidence of lasting neurologic sequelae. The mortality ranges from 17 % to greater than 30% in patients with neurological invol...

ConclusionCranioplasty has high complication rates, 23% in our cohort. Contrary to recent systematic reviews, early CP was associated with more complications (41%), explained by the higher incidence of pre-CP CSF flow disturbance and acute subdural hematoma as etiology of DC. CP in such patients should therefore be performed with highest caution.

This study aimed to determine the incidence of and the factors associated with PTH. We retrospectively reviewed patients who underwent DC for TBI at our institute between January 2014 and December 2018. We identified and compared the demographic, clinical, and radiological data, and 12-month functional outcome (as assessed by the Glasgow Outcome Scale [GOS]) between patients who developed PTH and those who did not. Logistic regression analyses were performed to identify risk factors for PTH. Additionally, the influence of PTH on unfavorable functional outcome was analyzed. PTH developed in 18 (18.95%) of the 95 patients wh...

Authors: Araujo-Castro M, Berrocal VR, Pascual-Corrales E Abstract Pituitary tumors (PTs) are a heterogeneous group of lesions of the central nervous system that are usually benign. Most of them occur sporadically, but 5% can do so within family syndromes, usually at a young age. There are differences by sex, age, race, and genetic factors in the prevalence of different tumor cell types and clinical presentation. Functioning-PTs (FPTs) are usually diagnosed earlier than non-functioning PTs (NFPTs). However, this depends on the PT type. Headaches and visual disturbances are the most frequent mass-effect symptoms, bu...

ConclusionThe accurate diagnosis of isolated BPC is not always straightforward, which is especially critical in the context of fetomaternal medicine. A  detailed description of posterior fossa malformations is to be preferred over unspecific terminology.

Hydrocephalus is rare in sarcoidosis, especially as the presenting symptom. Neurosarcoidosis as a cause of unexplained communicating hydrocephalus should be considered in cases of abnormal cerebrospinal fluid (CSF) and negative infectious and tumoral studies.

ABSTRACT Objective: To present a program of home physical exercises for patients with normal pressure hydrocephalus (NPH) and to evaluate adherence, acceptance and applicability; to verify possible changes in patients with NPH in the home physical exercise program, comparing patients with, and without, a ventriculoperitoneal shunt, regarding gait, quality of life, activities of daily living, static and dynamic balance and its impact on the risks of falling. Methods: This was a controlled clinical trial, with assessments in three moments (0, 10 and 18 weeks) at the home, from October 2015 to November 2017. Fifty-two patient...
