Pneumothorax is air collection between lungs and chest wall. Primary pneumothorax occurs without known respiratory disease. Secondary pneumothorax results from pre-existing respiratory conditions. UK incidence: 19/100,000 in males, 8/100,000 in females. 85% of pneumothoraces are primary, highest incidence in over 65s
Iatrogenic refers to illnesses caused by medical procedures or physician comments. Diagnostic procedures can lead to hemorrhage, infection, or organ perforation. Adverse drug reactions occur in 2-5% of hospitalized patients. Anaphylaxis is most common with penicillin, vaccines, and insulin
Pneumothorax is abnormal air collection between lung and chest wall. Primary spontaneous occurs without cause, secondary with lung disease. Traumatic pneumothorax results from chest wall injury or medical procedures. About 17-23 cases per 100,000 people yearly, more common in men
Pneumothorax occurs when air enters pleural space between lung and chest wall. Classified as spontaneous or traumatic, with primary and secondary types. Tension pneumothorax is life-threatening variant requiring immediate needle decompression
Pneumothorax can be open (through chest wall) or closed. Spontaneous pneumothorax occurs in 1-2% of neonates. Iatrogenic pneumothorax occurs more frequently than spontaneous. Men are 3-6 times more likely to develop pneumothorax than women
Chest X-ray is primary diagnostic tool. CT scan and ultrasound may be used for detailed imaging
