Air fluid level in lower lobe

• lung abscess

Ghon complex –> healed –> persistant cavity –> secondarily infected by Aspergillus flavus and form fungus balls

PAS stain –>

AAT deficiency –> Cirrhosis and HCC

• unsecreted polymerized AAT molecules accumualte –> resist digestion by diastase –> Glycogen stains in PAS –> appears reddish pink

Lung cancer? — white sputum, clear fluid?

• adenocarcinoma of the lung

Propofol:

• Highly lipophilic drugs –> pass into the brain tissue because it receives the major blood supply –> (rapid action) –> gradually other organs take in –> reduced availability in th ebrain –> effect wanes
• gaba agnoist,
• higly lipophilic
• long term sedation
• adverser: hypotension, high serum TG/lipase

Etomidate:

• gaba agnoist, hemo neutral
• reversible inhibition of cortisol –> reversible adrenocortical suppresion –> AVOIDED IN PATIENTS WITH SEPTIC SHOCK
• NOT FOR Maintainenece
