INTRODUCTION: Breathing pattern disorders (BPDs) are characterized by persistent, suboptimal breathing strategies that may result in additional musculoskeletal pain and/or dysfunction. The purpose of this case series was to examine the effects of Primal Reflex Release Technique (PRRT) and breathing exercise interventions in physically active individuals that presented with a primary complaint of musculoskeletal pain, a BPD, and startle reflexes. SUBJECTS: The assessment techniques described in Part 1 of this series were used to identify three student athletes (aged 16-22) who presented with musculoskeletal pain of the low back, mid back, and knee, BPDs, and startle reflexes...

The human body is in constant motion, from every breath that we take, to every visibly purposeful action that we perform. Remaining completely still on command is a major achievement as involuntary fluctuations in our motions are difficult to keep under control. Here we examine the noise-to-signal ratio of micro-movements present in time-series of head motions extracted from resting-state functional magnetic resonance imaging scans in 1048 participants. These included individuals with autism spectrum disorders (ASD) and healthy-controls in shared data from the Autism Brain Imaging Data Exchange (ABIDE) and the Attention-Deficit Hyperactivity Disorder (ADHD-200) databases...

While managing obstructive sleep apnea (OSA) or suspicious OSA patients, the otorhinolaryngologist frequently has to deal with patients undergoing repeated polysomnography (PSG) or portable monitoring (PM) and, on the other hand, should be confident about the quality and consistency of the polysomnographic diagnosis. The main polysomnographic traces compressed in a unique epoch, defined as compact PSG/PM (CP), which should be reported in all PSG/PM report, could represent an efficient tool to confirm the quality of PSG/PM diagnosis and to recognize the sleep breathing disorders (SBD): OSA, no-OSA SBD and overlap of OSA with no-OSA SBD...

BACKGROUND: Modafinil is a wake-promoting drug and has been widely used for daytime sleepiness in patients with narcolepsy and other sleep disorders. A recent case series reported that daily oral modafinil alleviated hypercapnic respiratory failure in patients with COPD. However, the precise action of modafinil on respiration such as hypercapnic and/or hypoxic ventilatory responses remains unclear. The aim of this study is to clarify the effect of modafinil on the ventilatory control...

BACKGROUND: Children with achondroplasia often have breathing problems, especially during sleep. The most important treatments are adenotonsillectomy (for treating upper obstruction) and/or neurosurgery (for resolving cervicomedullar junction stenosis). DATA SOURCES: We reviewed the scientific literature on polysomnographic investigations which assessed the severity of respiratory disorders during sleep. RESULTS: Recent findings have highlighted the importance of clinical investigations in patients with achondroplasia, differentiating between those that look for neurological patterns and those that look for respiratory problems during sleep...

OBJECTIVE: Sleep-disordered breathing (SDB) is among the most common diseases and includes a group of pathological conditions that form a severity continuum from primary snoring (PS) to obstructive sleep apnea (OSA). SDB presents a multifactorial etiology and in children, it is often linked to adenotonsillar hypertrophy, which may lead to an alteration of the breathing pattern. Therefore, several studies hinted at the existence of a correlation between SDB and the alteration of craniofacial growth...

BACKGROUND: The expanded disability status scale (EDSS) is a validated and reliable tool to assess the extent of disabilities in patients with multiple sclerosis (MS). However, the use of this tool has been found to be limited in assessing various symptoms of MS that are important. Our study aimed at evaluating the efficacy of a new scoring system, reverse nutech functional score (RNFS) as compared to EDSS in assessing patients with MS treated with human embryonic stem cell (hESC) therapy...

Neurological respiratory deficits are serious outcomes of West Nile virus (WNV) disease. WNV patients requiring intubation have a poor prognosis. We previously reported that WNV-infected rodents also appear to have respiratory deficits when assessed by whole-body plethysmography and diaphragmatic electromyography. The purpose of this study was to determine if the nature of the respiratory deficits in WNV-infected rodents is neurological and if deficits are due to a disorder of brainstem respiratory centers, cervical spinal cord (CSC) phrenic motor neuron (PMN) circuitry, or both...

BACKGROUND: Appropriate assessment and interventions for breathing patterns prior to assessment of the patient's musculoskeletal complaint may be beneficial. Breathing pattern disorders (BPDs) are remediable and influenced by biochemical, biomechanical, psychological, and/or unknown factors. The purpose of this clinical commentary is to demonstrate the integratration of a BPD assessment into a standard clinical musculoskeletal orthopedic examination. CLINICAL ASSESSMENT: The observation of a patient's breathing pattern begins when they enter the clinic, is followed by palpation and orthopedic tests, which allows for proper classification of BPDs...

: Spontaneous ventilation in mammals is driven by automatic brainstem networks that generate the respiratory rhythm and increase ventilation in the presence of increased carbon dioxide production. Hypocapnia decreases the drive to breathe and induces apnea. In humans, this occurs during sleep but not during wakefulness. We hypothesized that hypocapnic breathing would be associated with respiratory-related cortical activity similar to that observed during volitional breathing, inspiratory constraints, or in patients with defective automatic breathing (preinspiratory potentials)...

Breathing is a life-sustaining behavior that in mammals is accomplished by activation of dedicated muscles responsible for inspiratory and expiratory forces acting on the lung and chest wall. Motor control is exerted by specialized pools of motoneurons in the medulla and spinal cord innervated by projections from multiple centers primarily in the brainstem that act in concert to generate both the rhythm and pattern of ventilation. Perturbations that prevent the accomplishment of the full range of motor behaviors by respiratory muscles commonly result in significant morbidity and increased mortality...

PURPOSE OF REVIEW: Opioid-induced postoperative respiratory depression has garnered attention and calls for vigilance. However, a higher level of monitoring equates to increased use of hospital resources and is impractical to apply for all postoperative patients. Understanding the temporal pattern of postoperative respiratory emergency occurrences would allow for improved triage of monitoring resources for high-risk patients. Our objective is to describe the temporal pattern of risk of postoperative opioid-induced respiratory failure...

In 2015, the international guidelines for diagnosis and treatment of pulmonary hypertension (PH) were updated. Group 3 of the current classification includes PH associated with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), other pulmonary diseases with restrictive and obstructive pattern, sleep-disordered breathing, alveolar hypoventilation disorders, chronic exposure to high altitude, and developmental lung diseases [1]. PH associated with COPD and ILD is common but difficult to manage, as no long-term randomised controlled trial (RCT) has been conducted with specific pulmonary arterial hypertension (PAH) drugs in PH associated with COPD, and the one recent RCT in PH associated with ILD had to be stopped early due to a possible increased risk of death and side effects in the treatment group...

Upper and lower obstructive lung diseases can induce sleep complaints and can be part of the pathogenesis of sleep breathing disorders. In fact, the physiological changes of the pattern of respiration during sleep, added to the airways disease can lead to symptomatic worsening of rhinitis, asthma and chronic obstructive pulmonary diseases (COPD); moreover, their functional and anatomical features can lead to sleep breathing disorders such as obstructive sleep apnea syndrome (OSAS). This review highlights the above-mentioned relationships and the effect of disease management on its comorbidities and the patient's quality of life...

Obstructive sleep apnea syndrome (OSAS) is a well-recognized disorder conventionally diagnosed with an elevated apnea-hypopnea index. Prolonged partial upper airway obstruction is a common phenotype of sleep-disordered breathing (SDB), which however is still largely underreported. The major reasons for this are that cyclic breathing pattern coupled with arousals and arterial oxyhemoglobin saturation are easy to detect and considered more important than prolonged episodes of increased respiratory effort with increased levels of carbon dioxide in the absence of cycling breathing pattern and repetitive arousals...

Dysfunctional breathing is a term describing breathing disorders where chronic changes in breathing pattern result in dyspnoea and other symptoms in the absence or in excess of the magnitude of physiological respiratory or cardiac disease. We reviewed the literature and propose a classification system for the common dysfunctional breathing patterns described. The literature was searched using the terms: dysfunctional breathing, hyperventilation, Nijmegen questionnaire and thoraco-abdominal asynchrony. We have summarised the presentation, assessment and treatment of dysfunctional breathing, and propose that the following system be used for classification...

OBJECTIVES: Catathrenia is an uncommon and poorly understood disorder, characterized by groaning during sleep occurring in tandem with prolonged expiration. Its classification, pathogenesis, and clinical relevance remain debated, substantially due to the limited number of cases reported to date. We report a series of consecutive cases of catathrenia, their clinical and polysomnographic characteristics, and their subsequent management. METHODS: Consecutive patients with catathrenia who had undergone full polysomnography in our institution over a 5...
