An exception is when acute bronchitis is due to pertussis. [1] Tentative evidence supports honey and pelargonium to help with symptoms. [1] Acute bronchitis is one of the most common diseases. [3] [13] About 5% of adults are affected and about 6% of children have at least one episode a year. [7] [8] It occurs more often in the winter. [7]
Additionally, bronchitis is described as either acute or chronic depending on its presentation and is also further described by the causative agent. Acute bronchitis can be defined as acute bacterial or viral infection of the larger airways in healthy patients with no history of recurrent disease. [ 8 ]
Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used. [2] When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.
In severe or acute hypoosmolar hyponatremia, swelling of brain cells causes various neurological abnormalities, which in severe or acute cases can result in convulsions, coma, and death. The symptoms of chronic syndrome of inappropriate antidiuresis are more vague, and may include cognitive impairment , gait abnormalities , or osteoporosis .
There are many mimics that present with similar symptoms, such as vocal cord dysfunction, cardiac arrhythmias, cardiomyopathies, and gastroesophageal reflux disease. It is also important to distinguish those who have asthma with exercise worsening, and who consequently will have abnormal testing at rest, from true exercise-induced ...
Acute bronchitis is one of the more common diseases. [7] [14] About 5% of adults and 6% of children have at least one episode a year. [2] [15] Acute bronchitis is the most common type of bronchitis. [16] By contrast in the United States, in 2018, 9.3 million people were diagnosed with the less common chronic bronchitis. [17] [18]
The acute attacks classically present with dark-red photosensitive urine (often called port-wine urine), but this is a nonspecific symptom. [12] Physical examination often shows no abnormalities. [13] Hyponatremia is the most common electrolyte abnormality during acute attacks, occurring in 40% of patients and presenting as SIADH. [13]
Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate , abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
