Allgrove syndrome with amyotrophy.

Allgrove syndrome is an autosomal recessive disease mostly caused by mutations in the gene. It has variable clinical features but its cardinal features comprise the triad of achalasia, alacrimia and adrenal insufficiency. It typically develops during the first decade of life, but some cases have second and third decades onset.

Electromyography in Congenital Zika Syndrome.

Introduction: Congenital Zika virus syndrome is a distinct pattern of birth defects in fetuses infected by the Zika virus. It presents a broad clinical spectrum that includes occurrences of microcephaly, hypertonia, dysphagia, hyperexcitability, seizures, and arthrogryposis. Imaging findings show neuronal migration disorders.

Portable accelerometers for the evaluation of spatio-temporal gait parameters in people with Parkinson's disease: an integrative review.

Purpose: The progression of Parkinson's disease causes an increase in motor dysfunctions, which makes it necessary to evaluate and monitor these changes. This integrative review aimed to gather studies - without any language restrictions - on the use, advantages and disadvantages of portable accelerometers for the evaluation of spatio-temporal gait parameters in people with Parkinson's disease published between 2014 and 2019.

Methods: Articles were selected from the PubMed, Web of Science and Science Direct databases by combining descriptors from the Health Sciences Descriptors (DeCS) and Medical Subject Headings (MeSH) - "accelerometry", "accelerometer", "ActiGraph", "gait", "gait analysis", "gait rehabilitation", "walking inertial sensors", "Parkinson disease", "Parkinson" and "Parkinson's disease" - using OR and AND.

Diaphragmatic paralysis: Evaluation in infants with congenital Zika syndrome.

Background: Paralysis of the diaphragm in newborn infants can lead to recurrent infections and life-threatening respiratory insufficiency. The clinical diagnosis of unilateral diaphragmatic paralysis has been reported in infants with laboratory evidence of congenital Zika virus infection and/or the congenital Zika syndrome (CZS) phenotype but no evaluation of phrenic nerve function has been described. All reported infants have had accompanying arthrogryposis.

Respiratory muscle strength and lung function in the stages of Parkinson's disease.

Objective: To investigate parameters of lung function and respiratory muscle strength in different stages of Parkinson's disease (PD), as well as to determine their correlation with motor function and quality of life.

Study of cochlear microphonic potentials in auditory neuropathy.

Introduction: Auditory Neuropathy/Dyssynchrony is a disorder characterized by the presence of Otoacoustic Emissions and Cochlear Microphonic Potentials, an absence or severe alteration of Brainstem Evoked Auditory Potential, auditory thresholds incompatible with speech thresholds and altered acoustic reflexes. The study of the Cochlear Microphonic Potential appears to be the most important tool for an accurate diagnosis of this pathology.

Objective: Determine the characteristics of the Cochlear Microphonic in Auditory Neuropathy/Dyssynchrony using an integrative review.

Daytime sleepiness and Parkinson's disease: the contribution of the multiple sleep latency test.

Background. Sleep disorders are major nonmotor manifestations of patients with Parkinson's disease (PD), and excessive daytime sleepiness (EDS) is one of the most common symptoms. Objective.

The relationship between limit of Dysphagia and average volume per swallow in patients with Parkinson's disease.

The goal of this study was to obtain the limit of dysphagia and the average volume per swallow in patients with mild to moderate Parkinson's disease (PD) but without swallowing complaints and in normal subjects, and to investigate the relationship between them. We hypothesize there is a direct relationship between these two measurements. The study included 10 patients with idiopathic PD and 10 age-matched normal controls.

Quality of life related to swallowing in Parkinson's disease.

Swallowing difficulties in Parkinson's disease can result in decreased quality of life. The swallowing quality of life questionnaire (SWAL-QOL) is an instrument for specifically assessing quality of life with respect to swallowing, which has been little explored in patients with Parkinson's disease (PD). The goal of this study was to evaluate the quality of life with respect to swallowing in persons with PD compared to controls and at several stages of the disease using the SWAL-QOL.

Psychiatric comorbidities in patients with systemic lupus erythematosus: a systematic review of the last 10 years.

Objective: To analyze the frequency of psychiatric comorbidities in patients with systemic lupus erythematosus (SLE) using the systematic review method.

Methods: A systematic literature search was performed between April and July 2011 in the following databases: BIREME, PubMed and CAPES thesis database. This search prioritized studies published over the last ten years (2001-2011), involving the presence of psychiatric comorbidities in patients with SLE.

The impact of stimulation rates in vestibular evoked myogenic potential testing.

Unlabelled: Vestibular evoked myogenic potentials (VEMP) have been used in complementary otoneurological assessment, but the use of VEMP in clinical settings is limited. VEMPs can be used to assess vestibular function, particularly of the saccule, the inferior vestibular nerve, and/or the vestibular nucleus.

Objective: To verify the highest possible - and reliable - stimulation rate to obtain VEMPs.

Interleukin-6 promoter polymorphisms -174 G/C in Brazilian patients with systemic lupus erythematosus.

To investigate the association of the IL-6 gene promoter polymorphism (-174 G/C) with SLE susceptibility and disease features in Brazilian patients, a case-control study of 80 lupus cases and 60 volunteer healthy women was performed. Genotyping was carried out by polymerase chain reaction and PCR product was digested by HSP92II restriction enzyme, being after visualized in polyacrylamide gel. There were significant differences in the distribution of the IL-6 gene C/C polymorphism between the SLE and control groups (χ(2) = 8.

Primary hyperparathyroidism is associated with subclinical peripheral neural alterations.

Objective: Some case reports have suggested primary hyperparathyroidism (PHPT) and peripheral polyneuropathy (PPN) are associated; however, there are no reports of studies examining this possible relationship. The aim of this study was to evaluate peripheral nerve conduction in subjects with PHPT.

Methods: The study involved 17 patients with PHPT.

Resilience in migraine brains: decrease of coherence after photic stimulation.

Background: During migraine attacks, patients generally have photophobia and phonophobia and seek for environments with less sensorial stimulation. Present work aimed to quantify cortical partial directed coherence (PDC) of electroencephalographic (EEG) recordings from migraine patients and controls in occipital, parietal, and frontal areas with or without photic stimulation. Our hypothesis is that migraine patients with visual aura might have neuronal networks with higher coherence than controls even in interictal periods due to a predisposition in sensory cortical processing.

Swallowing in patients with Parkinson's disease: a surface electromyography study.

Our goal was to study deglutition of Parkinson's disease (PD) patients and normal controls (NC) using surface electromyography (sEMG). The study included 15 patients with idiopathic PD and 15 age-matched normal controls. Surface electromyography was collected over the suprahyoid muscle group.

[Auditory steady-state response in the auditory evaluation: clinical application].

Background: the auditory steady state response (ASSR) is an electrophysiological procedure that evaluates, at the same time, the hearing thresholds of both ears at various frequencies. This procedure reduces the time of testing and enables the stimulation of levels close to 125dB HL, characterizing residual hearing.

Aim: to verify the applicability of the ASSR to determine the hearing thresholds in different levels of sensorineural hearing loss.

[Repetitive stimulation test on the anconeus muscle for the diagnosis of myasthenia gravis: the mapping of its motor end-plate area].

Purpose: To map the motor end-plate area of the anconeus muscle and define the best place for positioning the recording electrodes in repetitive stimulation tests (RST) for the diagnosis of neuromuscular transmission disorders.

Method: The compound muscle action potential of the anconeus was recorded after stimulating the motor branch of the radial nerve that innervates it. By analyzing the waveforms registered at each point of the skin we were able to define the motor end-plate area.
