West Nile virus (WNV) is endemic in the Po valley area, Northern Italy, and within the legal framework of the national plan for the surveillance of human vector-borne diseases, WNV surveillance has over time been implemented. The surveillance plans are based on the transdisciplinary and trans-sectorial collaboration between regional institutions involved in public, animal, and environmental health. This integrated surveillance targets mosquitoes, wild birds, humans, and horses and aims at early detecting the viral circulation and reducing the risk of infection in the human populations...

INTRODUCTION: Acquired Chiari malformation and associated syringomyelia have been previously described following lumbar puncture/drainage, lumboperitoneal shunts, and spontaneous CSF leakage. In addition to these etiologies, space-occupying lesions such as meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are rare causes of acquired Chiari malformation and syringomyelia. We report a rare case of colloid cyst with hydrocephalus causing secondary Chiari malformation with syringomyelia...

OBJECTIVE Surgery is the definitive treatment of Chiari malformation Type I (CM-I). It involves posterior fossa decompression, which can be performed along with C-1 laminectomy, reconstructive duraplasty, or tonsil shrinkage. The aim of this study was to provide an updated systematic review and meta-analysis of the latest available evidence regarding posterior fossa decompression only (PFDO) versus posterior fossa decompression with duraplasty (PFDD) in the treatment of CM-I in children. METHODS A literature search was performed in compliance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for article identification, screening, eligibility, and inclusion...

INTRODUCTION: It was believed that Chiari type II malformation (CM-II) was always present in a myelomeningocele (MMC). In fact, it is associated in about 80 % of cases. Improvement of the hindbrain herniation after prenatal closure of MMC has challenged the idea that this condition was irreversible. Only two studies report ascent of the cerebellar tonsil after post-natal closure. This work aimed to study a large group of MMC patients who benefitted from a post-natal repair to evaluate the rate of long-term total reversibility of CM-II...

INTRODUCTION: Although many surgical treatment strategies for Chiari malformation type I (CM-I) have been reported, the most appropriate surgical technique remains controversial. It is wholly ascribable to the complicacy of pathological condition in CM-I. Recently, intraoperative neurophysiologic monitoring (INM) is becoming prevalent in spinal surgery. Indeed, motor-evoked potentials (MEPs) monitoring and somatosensory-evoked potentials (SSEPs) monitoring are standard tools to minimize the risk of neurologic injury and postoperative deficits...

Freezing of gait (FOG) is a disabling symptom that is common among patients with advanced Parkinson's disease (PD). External cues such as rhythmic auditory stimulation can help PD patients experiencing freezing to resume walking. Wearable systems for automatic freezing detection have been recently developed. However, these systems detect a FOG episode after it has happened. Instead, in this study, a new approach for the prediction of FOG (before it actually happens) is presented. Prediction of FOG might enable preventive cueing, reducing the likelihood that FOG will occur...

BACKGROUND: Posterior fossa decompression surgeries for Chiari malformations are susceptible to post-operative complications such as pseudomeningocele, external cerebrospinal fluid (CSF) leak, and meningitis. Various dural substitutes have been employed to improve surgical outcomes. OBJECTIVE: This study examined whether the collagen matrix dural substitute type correlated with the incidence of post-operative complications following posterior fossa decompression in adult patients with Chiari I malformations...

BACKGROUND: The technique for decompression of Chiari type I malformation relies on open exposure of craniocervical junction for suboccipital craniectomy and upper cervical laminectomy with or without duraplasty. There is no detailed technical report of a minimally invasive approach for Chiari decompression in adults. OBJECTIVE: To describe a mini-open technique for decompression of Chiari type I malformation (including duraplasty) in adults. METHODS: Six consecutive adult patients with symptomatic Chiari type I malformation underwent decompression through a 3 to 4 cm midline incision via a speculum retractor...

PURPOSE: Type I Chiari malformation (CMI) is a radiologically-defined structural dysmorphism of the hindbrain and posterior cranial fossa (PCF). Traditional radiographic identification of CMI relies on the measurement of the cerebellar tonsils in relation to the foramen magnum with or without associated abnormalities of the neuraxis. The primary goal of this retrospective study was to comprehensively assess morphometric parameters above the McRea line in a group of female CMI patients and normal controls...

BACKGROUND: Approximately 30% of patients treated by foramen magnum decompression (FMD) for Chiari I-associated-syringomyelia will show persistence, recurrence, or progression of the syrinx. OBJECTIVE: This study evaluates the clinical and radiological outcome of syringo-subarachnoid shunt (SSS) as the treatment for persistent syringomyelia after FMD. METHODS: Data was collected retrospectively. The primary outcome measurement was neurological function (assessed with the Modified Japanese Orthopedic Association (mJOA) scale)...

INTRODUCTION: 
 Pseudotumor cerebri (PTC) patients exhibit clear clinical signs and symptoms of higher intracranial pressure (ICP) without ventricular enlargement or mass lesions. The clinical picture of patients with PTC can sometimes be similar to that of Chiari Malformation type I (CMI). There is some evidence that Chiari I malformation and PTC may coexist, which raises the question of whether PTC is an idiopathic disease or a complication of posterior decompression surgery-treatment of choice for Chiari I malformation...

BACKGROUND: Chiari Malformation Type I is a hindbrain abnormality characterized by cerebellar tonsils descent beneath the foramen magnum, frequently associated with symptoms or brainstem compression, impaired cerebrospinal fluid circulation and syringomyelia. Foramen magnum decompression represents the most common way of treatment. Rarely, subdural fluid collection and hydrocephalus represent postoperative adverse events. The treatment of this complication is still debated, and physicians sometimes are faced with the doubt of when undergoing diversion surgery and when more conservative managements...

This work introduces a novel sieving gel for DNA electrophoresis using a classical click chemistry reaction, the copper (I)-catalyzed azide-alkyne cycloaddition (CuAAC), to cross-link functional polymer chains. The efficiency of this reaction provides, under mild conditions, hydrogels with near-ideal network connectivity and improved physical properties. Hydrogel formation via click chemistry condensation of functional polymers does not involve the use of toxic monomers and UV initiation. The performance of the new hydrogel in the separation of double stranded DNA fragments was evaluated in the 2200 TapeStation system, an analytical platform, recently introduced by Agilent that combines the advantages of CE in terms of miniaturization and automation with the simplicity of use of slab gel electrophoresis...

Structure-based epitope prediction drives the design of diagnostic peptidic probes to reveal specific antibodies elicited in response to infections. We previously identified a highly immunoreactive epitope from the peptidoglycan-associated lipoprotein (Pal) antigen from Burkholderia pseudomallei, which could also diagnose Burkholderia cepacia infections. Here, considering the high phylogenetic conservation within Burkholderia species, we ask whether cross-reactivity can be reciprocally displayed by the synthetic epitope from B...
