BACKGROUND "Row-a-boat" phenomenon (RBP) is a spontaneous upper-body movement in patients with advanced Duchenne muscular dystrophy (DMD), when sitting upright supported by a belt around the body in a wheelchair. However, the role of RBP has not been clarified. OBJECTIVES To support the hypothesis that RBP is an abnormal pattern of respiration to compensate for the atrophied respiratory muscl...

OBJECTIVES To discover the relation between initial symptoms, triggers and durations of attacks of paradoxical vocal fold movement disorder (PVFMD) and concurrent laryngeal and respiratory diseases. PATIENTS AND METHODS Twenty one PVFMD patients (17 females, 4 males; mean age 50 year; range 31 to 72 years) were included in the study. Diagnosis of PVFMD was established when inspiratory and/or ...

We present a case of Kaposi's sarcoma-related immune reconstitution inflammatory syndrome in an HIV-infected patient who developed fever, worsening pulmonary infiltrates with respiratory distress, and progression of skin tumors at the popliteal region and thigh that resulted in limitation on movement of the right knee joint at 3.5 months following a significant increase of CD4 count after combi...

despite improvement of mechanical ventilation devices for infants, lung injury still causes morbidity and mortality in many cases. to determine the effect of high frequency oscillatory ventilation (hfov) in infants with severe respiratory failure, 10 neonates were evaluated prospectively. mean gestational age of these patients was 35 weeks and alveolar-arterial oxygen gradient (a-ado2) and the ...

background : the present study was undertaken to ascertain whether (or not) long term occupational exposure to low (sub-tlv levels) atmospheric concentrations of chlorine gas was associated with any significant decrements in the parameters of pulmonary function and/or  increased prevalence of respiratory symptoms. methods : in this retrospective cohort study that was performed in 2012, 54 worke...

dust can be produced by almost all production processes in portland cement factory. dust exposure potentially can affect respiratory function. but evidence for respiratory effect of cement dust exposure has not been conclusive. in this study we assessed effect of cement dust exposure on respiratory function in a cement production factory. a respiratory symptoms questionnaire was completed and p...

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of death in patients with refractory epilepsy. SUDEP occurs more commonly during nighttime sleep. The details of why SUDEP occurs at night are not well understood. Understanding why SUDEP occurs at night during sleep might help to better understand why SUDEP occurs at all and hasten development of preventive strategies. Here we ai...

Most of the inverse modeling of body dynamics in sports assumes that every segment is 'rigid' and moves 'as a whole', although we know that uncontrolled wobbling masses exist and in specific condition their motion should be optimized, both in engineering and biology. The visceral mass movement within the trunk segment potentially interferes with respiration and motion acts such as locomotion or...

In the present study, we investigated in anesthetized rats the influences of the pontine rapid-eye-movement (REM) sleep center on trigeminally induced respiratory responses. We evoked the nasotrigeminal reflex by electrical stimulation of the ethmoidal nerve (EN5) and analyzed the EN5-evoked respiratory suppression before and after injections into the pontine reticular nuclei of the cholinergic...
