Endotracheal intubation and mechanical ventilation have traditionally been employed in patients with acute respiratory insufficiency. However, this form of management can have serious adverse effects, mainly infections and barotrauma. Noninvasive ventilation (NIV) has been shown to be an effective alternative, as it reduces both the frequency of complications and cost of care. In fact, NIV is c...

Mitochondrial myopathy is an important but uncommon cause of respiratory insufficiency in adults. We report the first case of respiratory insufficiency associated with adult-onset mitochondrial myopathy seen in a Chinese adult in Hong Kong. The patient presented with peripheral oedema and shortness of breath over 2 to 3 days. There was a history of gradual progressive limb weakness over approxi...

A 51-year-old male patient was receiving treatment for Mycobacterium abscessus infection for approximately 10 years. However, as his condition gradually progressed to type II respiratory insufficiency, he was referred to our hospital, which was near his home. Computed tomography on his first visit revealed an abscess in the right lower lobe. Because respiratory insufficiency was evident, he was...

Assessment of respiratory mechanics can play a central role in the management of critically ill patients undergoing artificial ventilation because of acute respiratory failure (ARF) [1]. This is a condition defined by a rapid deterioration in pulmonary gas exchange that may be due either to alterations in the mechanical properties of the respiratory system leading to ventilation–perfusion misma...

BACKGROUND Neurological respiratory insufficiency strongly correlates with mortality among rodents infected with West Nile virus (WNV), which suggests that this is a primary mechanism of death in rodents and possibly fatal West Nile neurological disease in human patients. METHODS To explore the possibility that neurological respiratory insufficiency is a broad mechanism of death in cases of v...

West Nile virus (WNV) disease can be fatal for high-risk patients. Since WNV or its antigens have been identified in multiple anatomical locations of the central nervous system of persons or rodent models, one cannot know where to investigate the actual mechanism of mortality without careful studies in animal models. In this study, depressed respiratory functions measured by plethysmography cor...
