difference between acute and chronic pancreatitis
irreversibly of damage
pathogenesis of chronic pancreatitis
repeated bouts of acute pancreatitis
- loss of parencyhma
- duct distortion
- fibrosis
- impaired secretion
duct flow becomes obstructed as a result of
fibrosis
pancreatic concretions
pancreatic concretions
due to increased protein concentration in pancreatic fluid

spontaneous ptx
due to rupture of apical blebs
tall, thin, healthy males
secondary spontaneous ptx
underlying path: COPD, trauma, infections
tension ptx
one-way valve effect
air can enter pleural space but not not exit
pressure on mediastinum –> hemodynamic instability
- mediastinal shift, tracheal deviation AWAY
tracheal deviation in tension ptx
AWAY
pneumothorax presentation
Pleuritic Chest Pain, Tracheal Deviation, Hyperresonace, Occurs Suddenly, reduced breath sounds, absent fremitus, x ray shows collapse
ptx diagnosis
chest xray
hyperlucent lung fields due to air accumulation
visceral pleural line
spontaneous ptx - tracheal deviation
spontateous: deviates towards affected lung due to decreased pressure from atelectasis on that side
tension ptx - tracheal deviation
away from affected lung, due to increased pressure on that side
tension ptx symptoms
can also have shock, JVD due to compression of SVC
spontaneous ptx if untreated
progress to tension ptx
large tension ptx
hemodynamic instability due to pressure on great vessels
treatment of small spontaneous ptx
resolves spontenous
o2 can expedite recovery
large, simple pneumothorax treatment
