AIMS To evaluate patterns of multiorgan dysfunction and neurologic outcome in children with respiratory and cardiac arrest after drowning. METHODS Single center retrospective chart review of children aged 0-21 years admitted between January 2001 and January 2012 to the pediatric intensive care unit at Children's Hospital of Pittsburgh with a diagnosis of drowning/submersion/immersion. Organ d...

The central nervous system plays a critical role in the normal control of arterial blood pressure and in its elevation in virtually all forms of hypertension. Mitochondrial dysfunction has been increasingly associated with the development of hypertension. Therefore, we examined whether mitochondrial dysfunction occurs in the brain in hypertension and characterized it at the molecular scale. Mit...

The association of autism spectrum disorders with oxidative stress, redox imbalance, and mitochondrial dysfunction has become increasingly recognized. In this study, extracellular flux analysis was used to compare mitochondrial respiration in lymphoblastoid cell lines (LCLs) from individuals with autism and unaffected controls exposed to ethylmercury, an environmental toxin known to deplete glu...

BACKGROUND Questionnaire and spirometry were applied to post-tuberculosis indigenous and non-indigenous individuals from Dourados, Brazil, to investigate the prevalence of chronic respiratory symptoms and pulmonary dysfunction. METHODS This was a cross-sectional study in cured tuberculosis individuals as reported in the National System on Reportable Diseases (SINAN) from 2002 to 2012. RESUL...

Duchenne muscular dystrophy (DMD) is a progressive striated muscle disease that is characterized by skeletal muscle weakness with progressive respiratory and cardiac failure. Together respiratory and cardiac disease account for the majority of mortality in the DMD patient population. However, little is known regarding the effects of respiratory dysfunction on the dystrophic heart. The studies d...

Multiple organ system failure is a major cause of mortality in the adult respiratory distress syndrome (ARDS). We serially evaluated parameters of multiple organ function in 24 patients during the first week after the diagnosis of ARDS and related them to outcome. The adult respiratory distress syndrome was associated with sepsis (n = 16), postoperation (n = 7), and trauma (n = 1). Fourteen of ...

BackgroundRespiratory tract viruses are the second most common cause of olfactory dysfunction. As we learn more about effects severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with recognition that dysfunction is a key symptom this disease process, there greater need than ever for evidence-based management postinfectious (PIOD).ObjectiveOur aim was to provide an practical guide PIOD...

Respiratory muscles play an important role in the origin of respiratory sensations. Data dissecting the role of the diaphragm and other inspiratory muscles are scarce. This study aimed to determine the impact of diaphragm dysfunction following inspiratory resistive loading on respiratory-related evoked potentials considered as a neurophysiological substrate of certain types of respiratory sensa...

Respiratory muscle testing is often limited to noninvasive volitional tests such as vital capacity and maximal static pressures. We report the case of a 12-year-old boy with congenital muscular dystrophy (CMD) in whom invasive and non-volitional respiratory muscle tests showed an elective diaphragmatic dysfunction with the preservation of expiratory muscle strength. This finding, coupled with a...

Since the early 1970s there has been an ongoing debate regarding the wisdom of promoting unassisted spontaneous breathing throughout the course of critical illness in patients with severe respiratory failure. The basis of this debate has focused on the clinical relevance of opposite problems. Historically, the term "disuse atrophy" has described a situation wherein sustained inactivity of the r...
