background: respiratory problem is one of the major health hazards in dust-exposed workers; it is a major cause of morbidity and mortality all over the world. objective: to determine the prevalence of respiratory problems and lung function impairment among quarry workers in ebonyi state, nigeria. methods: respiratory problems and lung function were studied in 403 quarry workers aged 10–60 years...
objective rubinstein-taybi syndrome is a rare genetic disorder with characteristic featuresincluding downward slanting palpebral fissures, broad thumbs and halluces,and mental retardation. systemic features may involve cardiac, auditory,ophthalmic, endocrine, nervous, renal and respiratory systems. this syndromeis sporadic in nature and has been linked to microdeletion at 16p 13.3 encodingcreb-...
Deep diving refers to saturation diving to a depth of more than 180 m (1.9 MPa ambient pressure). In the 1990s diving to 400 m may be necessary on the Norwegian continental shelf. The safety margins are narrow and the respiratory system is subject to great strain at such depths. The respiratory resistance increases and the dynamic lung volumes are reduced as the pressure increases due to enhanc...
Prader-Willi syndrome (PWS) is a genetic neurodevelopmental disorder that presents with hypotonia and respiratory distress in neonates. The Necdin-deficient mouse is the only model that reproduces the respiratory phenotype of PWS (central apnea and blunted response to respiratory challenges). Here, we report that Necdin deletion disturbs the migration of serotonin (5-HT) neuronal precursors, le...
R.D. Anbar (ed.), Functional Respiratory Disorders: When Respiratory Symptoms Do Not Respond to Pulmonary Treatment, Respiratory Medicine, DOI 10.1007/978-1-61779-857-3_2, © Springer Science+Business Media, LLC 2012 Abstract The management of respiratory diseases with organic causes often can be complicated by the emergence of concurrent functional respiratory symptoms. Thus, clinicians must be...
BACKGROUND Dysregulated respiratory control may play a role in the pathophysiology of panic disorder. This could be due to abnormalities in brain stem respiratory nuclei or to dysregulation at higher brain levels. Results from previous studies using the doxapram model of panic have yielded an unclear picture. A brief cognitive manipulation reduced doxapram-induced hyperventilation in patients, ...
