INTRODUCTION: Patent foramen ovale (PFO) is associated with cryptogenic stroke (CS) and migraine with aura (MA). Endothelial dysfunction (ED) is a risk factor for development of cardiovascular disease, but might also be involved in migraine pathophysiology. Short-term worsening of migraine has been described after closure of PFO. We evaluated endothelial function in patients with CS and PFO, before and after closure of PFO, and in patients with migraine, whether changes in endothelial function was related to a change in migraine frequency...

The objective was to study the prevalence and characterization of pediatric migraine triggers and to compare results to this retrospective study. A total of 101 pediatric patients with ICHD-II migraine with and/or without aura were instructed to prospectively complete a diary dealing with attacks triggers for a 3-month period. Each subject reported at least 1 trigger (range: 1-14) with a total number of 532 attacks and a median per subject of 3. Lack of sleep (51.4%), stress (44.6%), warm climate (41.9%), noise (32...

Background: Providing a self-care program appropriate for patient needs in a supportive educative nursing system format could reduce migraine-induced disability. This study was designed to determine the effectiveness of Orem's self-care program on headache related disability in migraine patients. Methods: In this randomized clinical trial, episodic migraine patients with or without aura who signed the informed consent were randomly assigned to two groups (44 patients each). The data collection tools included a demographic questionnaire, the Migraine Disability Assessment (MIDAS) questionnaire, an Orem cognition form, and a self-care checklist...

Lipoid proteinosis (LP) is a rare autosomal recessive disease characterized by deposition of hyaline material in skin and mucosae. Epilepsy, as an extracutaneous manifestation associated with typical mesial temporal calcifications, has already been identified, but its characteristics and long-term prognosis have not been thoroughly investigated. We included 7 consecutive patients with LP with typical intracranial calcifications out of 16 patients with ECM1 mutations and investigated the semiologic features, ictal and interictal EEG findings, and long-term prognosis of epilepsy in this genodermatosis...

The migraine aura is characterized by transient focal cortical disturbances causing dramatic neurological symptoms that are usually followed by migraine headache. It is currently not understood how the aura symptoms are related to the headache phase of migraine. Animal studies suggest that cortical spreading depression, the likely mechanism of migraine aura, causes disruption of the blood-brain barrier and noxious stimulation of trigeminal afferents leading to activation of brainstem nuclei and triggering of migraine headache...

INTRODUCTION: Tumor biopsies for detecting epidermal growth factor receptor mutations (EGFRm) in advanced non-small cell lung cancer (NSCLC) are invasive, costly and not always feasible for patients with late-stage disease. The clinical utility of the cobas(®) EGFR Mutation Test v2 with plasma samples from patients with NSCLC at disease progression following previous EGFR-tyrosine kinase inhibitor (TKI) therapy was investigated to determine osimertinib treatment eligibility. METHODS: Matched tumor tissue and plasma samples from patients screened for AURA extension and AURA2 phase II studies were tested for EGFRm using tissue- and plasma-based cobas(®) EGFR Mutation Tests v2...

INTRODUCTION: The onset of obesity at young ages is strongly associated with the early development of type 2diabetes (T2D). The shape of the curves of glucose and insulin curves during an oral glucose tolerance test (OGTT) could predict the risk of developing T2D. OBJECTIVE: To analyse the morphology of the OGTT and determine T2D risk factors in a mainly Caucasian population of children and adolescents. METHODS: Observational retrospective study including 588 patients (309 males, 279 females) with a mean age of 11...

Discrimination of odorous molecules in amniotic fluid occur after 30 weeks' gestation; fetuses exhibit differential responses to maternal diet. Olfactory reflexes enable reliable neonatal testing. Olfactory bulbs can be demonstrated reliably by MRI after 30 weeks' gestation, and their hypoplasia or aplasia also documented by late prenatal and postnatal MRI. Olfactory axons project from nasal epithelium to telencephalon before olfactory bulbs form. Fetal olfactory maturation remains incomplete at term for neuronal differentiation, synaptogenesis, myelination, and persistence of the transitory fetal ventricular recess...

Laccases are multicopper oxidases that catalyze aromatic and nonaromatic compounds with concomitant reduction of molecular oxygen to water. They are of great interest due to their potential biotechnological applications. In this work we statistically improved culture media for recombinant GILCC1 (rGILCC1) laccase production at low scale from Ganoderma lucidum containing the construct pGAPZαA-GlucPost-Stop in Pichia pastoris. Temperature, pH stability, and kinetic parameter characterizations were determined by monitoring concentrate enzyme oxidation at different ABTS substrate concentrations...

Cluster headache (CH) is a rare and severe syndrome characterized by the recurrence of unilateral pain attacks, of short duration (15-180min), and associated with ipsilateral cranial autonomic symptoms. Although, not formally included in the International Classification of Headache Disorders, hemiplegic cluster headache (HCH) is an even more rare subtype of CH in which typical attacks can be accompanied by visual, sensory, and/or aphasic migrainous auras that have a variable propensity to evolve in reversible hemi-motor symptoms...

Myotonic dystrophy type 1 (DM1) is the most frequent muscular dystrophy worldwide with complex, multi-systemic, and progressively worsening symptoms. There is currently no treatment for this inherited disorder and research can be challenging due to the rarity and variability of the disease. The UK Myotonic Dystrophy Patient Registry is a patient self-enrolling online database collecting clinical and genetic information. For this cross-sectional "snapshot" analysis, 556 patients with a confirmed diagnosis of DM1 registered between May 2012 and July 2016 were included...

Migraine auras are typically visual in nature but can manifest as disturbances in somatosensory, auditory, and olfactory senses. Reports of multiple sensory auras are rare in the literature, but their existence may offer novel insights into the pathogenesis of this highly common yet complex neurological condition. Here we report a case of multiple sensory auras involving somatosensory, auditory, and olfactory disturbances in a patient with migraine without visual manifestations. A 45-year-old woman with a 20-year history of migrainous headaches presented with complaints of rightsided facial and hand numbness and paraesthesia...

A patient is reported with reversible pure alexia in the context of migraine with aura. Following previous, anecdotal reports, the present study is the first to formally assess word reading, writing, and other linguistic and visual processing and to compare these to a patient with stroke-related pure alexia. The reading impairment, suggestive of letter-by-letter reading, was observed across 7 days but had remitted at a 3-month follow-up. The deficit also affected recognition of letters, suggesting a functional impairment at the level of letter recognition, not just word reading...
