Triptan
wiki
Triptans are a family of tryptamine-based drugs used as abortive medication in the treatment of migraines and cluster headaches.
While effective at treating individual headaches, they do not provide preventive treatment and are not considered a cure.
The drugs of this class act as agonists for serotonin 5-HT1B and 5-HT1D receptors at blood vessels and nerve endings in the brain.
The first clinically available triptan was sumatriptan

Air leak syndrome
escape of air fromt he traceobronchial tree into other body spaces where it is not normally present. It is named according to the location of the air, for example, it is called pneumothorax (pleural space), pneumomediastinum (mediastinum), and subcutaneous emphysema (subcutaneous tissues)
treatment for tension pneumothorax
emergent needle thoracostoy, life-saving and should be done as soon as possible, no need for imaging confirmation. vein needle is inserted into the third intercostal space at the mid clavicular line to evacuate the air and relieve the tension
why is a tension pneumothorax life-threatending?
decreases venous return to heart
major adverse effect of acetaminophen overdose
hepatotoxicity
large doses of acetaminophen deplete which molecule, what is essential for
Glutathione is essential for metabolism in the liver to nontoxic compounds
what doses are dangerous for acetaminophen overdose
hepatic necrosis is rare with ingestion less than 10 g and death is rare with less than 15 g
effects of acetaminophen ingestion are delayed, taking how long?
24-36 hours
name of acetaminophen nongram

hypokalemia and metabolic alkalosis, increased neutrophils
Screening of cushing syndrome
first 24 hour urinary cortisol, if it is 4 times as normal then it can make the diagnosis
test to distinguish between adrenal hyperplasia and adrenal adenoma
high dose dexamethason supression test
how to distinguish between primary and secondary cushings
measurement of plasma ACTH
