The current outbreak of Zika virus (ZIKV) in South America is one of the most serious public health emergencies since the Ebola outbreak of West Africa [2014]. ZIKV belongs to the flaviviridae family and has two lineages (Asian and African). The virus was first discovered in Uganda [1947] and the first human infection was identified in Nigeria [1952]. The current epidemic is the third of its type after that of Yap Island, Micronesia [2007] and French Polynesia [2013]. Phylogenetic studies revealed that the current strain shares about 99...

BACKGROUND AND PURPOSE: The syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) can present as sudden onset of focal neurological deficits which are clinically and radiologically indistinguishable from an ischaemic stroke. Its diagnosis requires a lumbar puncture (LP), which contraindicates intravenous thrombolytic therapy (IV-tPA). METHODS: All patients referred to our stroke centre as a stroke code resulting in a final diagnosis of HaNDL syndrome from June 2005 to June 2015 were retrospectively analysed...

Immunotherapeutic strategies to treat neurodegenerative disorders have inspired the scientific community. The aim of our review is to address the translational aspects of neuroimmunology to describe the efficacy of immunotherapy in the treatment of pediatric neurodegenerative disorders. In the studies we analyzed IVIG were found to be efficient in the treatment of post-streptococcal neurodegenerative disorders, even if in PANDAS, plasma-exchange (PE) showed a higher efficiency. IVIG were also successfully used in ADEM and Guillan-Barré syndrome...

Simulation is a frontier for disseminating knowledge in almost all the fields of medicine and it is attracting growing interest because it offers a means of developing new teaching and training models, as well as of verifying what has been learned in a critical setting that simulates clinical practice. The role of simulation in neurology, until now limited by the obvious physical limitations of the dummies used to train students and learners, is now increasing since, today, it allows anamnestic data to be related to the instrumental evidence necessary for diagnosis and therapeutic decision-making, i...

OBJECTIVES: Hyperechogenicity of the substantia nigra on transcranial sonography is used for diagnosing Parkinson disease (PD). Cutoff values for the substantia nigra echogenic area, defining substantia nigra hyperechogenicity, vary among ultrasound systems from different manufacturers. In this study we wanted to determine the cutoff criterion for a Toshiba (Tokyo, Japan) system and to assess its diagnostic value. METHODS: Three hundred participants (controls, n = 138; patients with PD, n = 105; and patients with essential tremor, n = 57) underwent transcranial sonography following a standardized protocol...

BACKGROUND: Aetiological diagnosis for meningitis remains a challenge and often a thorough Cerebrospinal fluid (CSF) examination may not give a precise diagnosis as at times CSF findings may simulate meningitis like picture as in carcinomatous meningitis, chemical meningitis, early stages of Guillan bare syndrome, subarachnoid hemorrhage, ICSOL, brain abscess, intracranial extension of epidural or subdural infection. Lesions of tissue rich in enzymes may cause enzymatic release on tissue destruction, so also in meningitis and many enzymes are known to be present in abundance in nervous system...

HIV-1-associated Guillan-Barre syndrome (hGBS) is an ascendant progressive polyradiculoneuropathy described throughout the course of the viral disease, mainly associated with the acute retroviral syndrome. HGBS is occasionally described in severely immunocompromised subjects in the context of the immune reconstitution inflammatory syndrome. The case described occurred soon after the start of a combined antiretroviral treatment in an HIV-1 infected patient with ulcerative colitis in the absence of severe immunosuppression...

In watersheds of equatorial West Africa, monophyletic groups of killifish species (genus Aphyosemion) occur in discrete altitudinal ranges, low altitude species (LA, sea level to ∼350 m) or high altitude species (HA, 350 to 900 m). We investigated the hypothesis that local adaptation to altitude by the LA and HA species would be revealed as divergent effects of temperature on their physiological energetics. Two species from each group (mass ∼350 mg) were acclimated to 19, 25 and 28°C, with 19 and 28°C estimated to be outside the thermal envelope for LA or HA, respectively, in the wild...

Mucoadhesive chitosan (CS) and/or hydroxypropyl-methylcellulose (HPMC) tablets for gastric drug delivery of acyclovir (ACV) have been developed in order to improve the ACV oral bioavailability. Swelling, bioadhesive and dissolution studies were carried out in two acidic media (pH 1.5 and 4) in order to determine the tablets behaviour in both fed and fasted states. All the designed tablets showed good mucoadhesive properties on gastric mucosa due to the presence of CS and/or HPMC. In vitro dissolution of ACV from tablets was influenced by the swelling behaviour of each polymer...

BACKGROUND: Patients who present with symptoms mimicking ischaemic stroke (IS), but have a different diagnosis, are known as stroke mimics (SM). The necessity for rapid administration of intravenous thrombolysis in patients with acute IS may lead to treatment of patients with conditions mimicking stroke. A variable proportion of patients with SM (1.4-14%) are currently treated with intravenous tissue plasminogen activator therapy (IV-tPA). The outcome of these patients is generally favourable and complications are rather infrequent...
