Noninvasive ventilation in difficult endotracheal intubation: systematic and review analysis.

Noninvasive ventilation has been widely used in the management of acute respiratory failure in appropriate clinical settings. In addition to known benefit of alleviating the need for invasive mechanical ventilation, recent literature suggested its beneficial use in the process of endotracheal intubation. Search of the PubMed database and manual review of selected articles investigating the methods and outcomes of endotracheal intubation in difficult airway due to hypoxemic respiratory failure and the role of noninvasive ventilation in this process.

A 26-Year-Old Woman With a Small Right Lung and a Right-Sided Heart.

A 26-year-old woman presented with abnormal findings on a chest radiograph. She had no significant history other than a fever 4 months prior to presentation that had resolved without a definite cause identified. She denied cough, shortness of breath, chest pain, history of smoking, environmental exposures, or prior pregnancies.

A 34-Year-Old Woman With Recurrent Right-Sided Chest Pain and Dyspnea.

A 34-year-old woman presented with her third episode of acute-onset right-sided chest pain and dyspnea. She had two prior similar occurrences of right-sided sharp, pleuritic chest pain with radiation to the back and dyspnea. Chest radiographs during these presentations revealed a small apical right-sided pneumothorax that was managed conservatively with high-flow oxygen.

A 44-year-old man with bilateral pneumothorax.

A 44-year-old man presented with a 3-day history of persistent upper-back pain, chest discomfort, and dyspnea. He denied any precipitating events such as trauma or vigorous activity before the presentation of symptoms. His exercise capacity had been excellent.

A 22-Year-Old Nonsmoker With Diffuse Cystic Lung Disease.

A 22-year-old previously healthy woman was evaluated in pulmonary clinic for shortness of breath and cough that had been slowly progressive over 3 months. She otherwise reported being fully functional and attended her college graduation a week prior to evaluation. She had no history of smoking, illicit drug use, connective tissue disease, or noxious exposures.

Hypocretin Deficiency Associated with Narcolepsy Type 1 and Central Hypoventilation Syndrome in Neurosarcoidosis of the Hypothalamus.

We report a case of a 53-year-old man presenting with depressed alertness and severe excessive sleepiness in the setting of neurosarcoidosis. Neuroimaging demonstrated hypothalamic destruction due to sarcoidosis with a CSF hypocretin level of 0 pg/mL. The patient also experienced respiratory depression that presumably resulted from hypocretin-mediated hypothalamic dysfunction as a result of extensive diencephalic injury.

A 55-year-old man with a small right lung and a right-sided heart.

A healthy 55-year-old man without known medical problems presented for a routine physical examination and was found to have an abnormal ECG. He denied chest pain, dyspnea, palpitations, dizziness, or syncopal episodes. He also denied orthopnea, paroxysmal nocturnal dyspnea, and lower-extremity edema.

A 65-year-old man with persistent cough and large nodular opacity.

A 65-year-old Asian man with a history of chronic hepatitis B infection presented to our pulmonary clinic for second opinion of his chronic, persistent, nonproductive cough. He was evaluated 10 months earlier with chest CT scan, which revealed a large lingular nodular opacity that was diagnosed as nodular cryptogenic organizing pneumonia by CT scan-guided percutaneous lung biopsy. Systemic corticosteroids were initiated and continued over the next 10 months.

A plasmapheresis protocol for refractory pulmonary alveolar proteinosis.

Pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by the accumulation of proteinaceous material within the lungs. While typically managed with whole lung lavage (WLL), more recent PAP therapies aimed at reducing granulocyte-macrophage colony stimulating factor autoantibodies (anti-GM-CSF) have reduced symptoms and improved lung function. We present a patient with PAP refractory to WLL, exogenous GM-CSF and rituximab who underwent a novel plasmapheresis protocol as a therapeutic trial.

A rare occurrence of pulmonary alveolar proteinosis after lung transplantation.

We present a case of pulmonary alveolar proteinosis (PAP) initially diagnosed 28 months after left single-lung transplantation for idiopathic pulmonary fibrosis. The diagnosis was based upon the presence of periodic acid-Schiff (PAS)-positive and surfactant immunostain-positive acellular lipoproteinaceous material within alveoli seen on transbronchial biopsy as well as in bronchoalveolar lavage fluid. The patient eventually also displayed a characteristic "crazy paving" pattern on radiographic imaging.

The use of a home exercise program based on a computer system in patients with chronic obstructive pulmonary disease.

Purpose: To test the effectiveness of a home exercise program based on a user-friendly, computer system, the Nintendo Wii Fit.

Methods: In this longitudinal study, 25 clinically stable patients with chronic obstructive pulmonary disease began a 6-week nonintervention (baseline) period followed by 12 weeks of Wii exercise training at home. Patients were instructed to exercise 5 or more days per week.
