We have focused on the epidemiology and immunobiology of Zika virus (ZIKV) infection and factors associated with the development of Guillain-Barré syndrome (GBS) and other neurological syndromes in Cúcuta, the capital of North Santander department, Colombia. Data of patients with ZIKV disease reported to the national population-based surveillance system were used to calculate the basic reproduction number (R0) and the attack rates (ARs) as well as to develop epidemiological maps. Patients with neurological syndromes were contacted and their diagnoses were confirmed...

BACKGROUND AND PURPOSE: Anxiety is common in Parkinson's disease (PD) and has a great influence on quality of life. However, little is known about risk factors for development of anxiety in PD. We investigated which factors were associated with longitudinal changes in severity of anxiety symptoms and development of future anxiety in patients who were not anxious at baseline. METHODS: Analyses were performed on data of the PROfiling PARKinson's disease (PROPARK) cohort, a 5-year hospital-based longitudinal cohort of over 400 patients with PD who have been examined annually...

Familial Dysautonomia (FD) is a neurodegenerative disease in which aberrant tissue-specific splicing of IKBKAP exon 20 leads to reduction of IKAP protein levels in neuronal tissues. Here we generated a conditional knockout (CKO) mouse in which exon 20 of IKBKAP is deleted in the nervous system. The CKO FD mice exhibit developmental delays, sensory abnormalities, and less organized dorsal root ganglia (DRGs) with attenuated axons compared to wild-type mice. Furthermore, the CKO FD DRGs show elevated HDAC6 levels, reduced acetylated α-tubulin, unstable microtubules, and impairment of axonal retrograde transport of nerve growth factor (NGF)...

Postural orthostatic tachycardia syndrome and neurocardiogenic syncope are clinical manifestations of autonomic nervous system dysfunction (dysautonomia) that can lead to impaired daily functions. We report two young patients presenting with dysautonomia and autoimmune disease who both received autologous adipose stem cells (ASCs) infusions. This report will be the first description of ASCs therapy for patients with combined dysautonomia and autoimmune disease. Case1: A 21 year female presented at 12 years of age with escalating severe dysautonomia with weight loss and gastrointestinal (GI) symptoms...

Aluminium (Al) oxyhydroxide (Alhydrogel(®)), the main adjuvant licensed for human and animal vaccines, consists of primary nanoparticles that spontaneously agglomerate. Concerns about its safety emerged following recognition of its unexpectedly long-lasting biopersistence within immune cells in some individuals, and reports of chronic fatigue syndrome, cognitive dysfunction, myalgia, dysautonomia and autoimmune/inflammatory features temporally linked to multiple Al-containing vaccine administrations. Mouse experiments have documented its capture and slow transportation by monocyte-lineage cells from the injected muscle to lymphoid organs and eventually the brain...

After prompt diagnosis, severe myasthenia gravis and Guillain-Barré syndrome (GBS) usually require management in the intensive care unit. In the myasthenic patient, recognition of precipitating factors is paramount, and frequent monitoring of bulbar, upper airway, and/or respiratory muscle strength is needed to identify impending myasthenic crisis. Noninvasive ventilation can be attempted prior to intubation and mechanical ventilation in the setting of respiratory failure. Cholinesterase inhibitors should be discontinued, but resumed prior to extubation, and steroid dosage could be increased once the airway is secured...

REVIEW
Marija Kojic, Brandon Wainwright
Development of the nervous system requires a variety of cellular activities, such as proliferation, migration, axonal outgrowth and guidance and synapse formation during the differentiation of neural precursors into mature neurons. Malfunction of these highly regulated and coordinated events results in various neurological diseases. The Elongator complex is a multi-subunit complex highly conserved in eukaryotes whose function has been implicated in the majority of cellular activities underlying neurodevelopment...

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a proven threat of cardiac dysautonomia with paucity of studies from India. Poor disease control makes it further worse with co-existence of hypertension in majority. Heart rate variability (HRV) is a validated noninvasive tool to assess cardiac autonomic status. AIM: We studied HRV parameters of type 2 diabetics looking for effects of disease control and other co-existing risk factors. MATERIALS AND METHODS: Ninety-eight hypertensive and forty normotensive under-treatment, Gujarati type 2 diabetics were evaluated for disease control and risk stratification...

BACKGROUND: Compulsive movements, complex tics and stereotypies are frequent, especially among patients with autism or psychomotor retardation. These movements can be difficult to characterize and can mimic other conditions like epileptic seizures or paroxysmal dystonia, particularly when abnormal breathing and cerebral hypoxia are induced. CASE PRESENTATION: We describe an 18-year-old patient with Asperger syndrome who presented with attacks of tonic posturing of the trunk and neck...

Small fiber neuropathy is a painful sensory nervous system disorder characterized by damage to unmyelinated C- and thinly myelinated Aδ- nerve fibers, clinically manifested by burning pain in the distal extremities and dysautonomia. The clinical onset in adulthood suggests a time-dependent process. The mechanisms that underlie nerve fiber injury in small fiber neuropathy are incompletely understood, although roles for energetic stress have been suggested. In the present study, we report time-dependent degeneration of neurites from dorsal root ganglia neurons in culture expressing small fiber neuropathy-associated G856D mutant Nav1...
