Medicine shelf quizlet Flashcards
Bilateral Hilar Adenopathy
think Sarcoidosis!! (non caseasting granulomas, interstitial lung disease, hypercalcemia and erythema nodosum)
Asbestosis: 1) location in lung 2) type of cancer risk 3) gross physical findings 4) histo findings 5) at risk population
- LOWER lobes
- mesothelioma & bronchogenic carcinoma
- pleural calcifications (plaques)
- asbestosis fiber=dumb bell
- shipyard workers, insulation, brake lining
Patient is a sand blaster/miner/glass or pottery worker…at risk for what lung disease?
SILICOSIS-Fibrosis of UPPER lobes of lungs
What are patients with Silicosis at risk for?
Pulmonary TB (b/c of egg shell calcifications of upper lung fields provide “nest” for TB)
COAL Miner’s Disease
- IgA and IgG increased with decreased C3
- positive ANA
- small round nodular densities
- “CAPLAN SYNDROME”if with RA of lung
PULMONARY HYPERTENSION IS DEFINED AS:
PULMONARY ARTERY PRESSURE >25MMHG OR >35MMHG DURING EXCERCISE (nml: 10-14mmHg)
What are results of Pulmonary Hypertension?
Atherosclerosis, intimal fibrosis of pulmonary arteries
Treatment for Pulmonary Hypertension?
1st: IV prostacyclins or other VASODILATORS (adenosine, NO)
2nd: Calcium Channel Blocker
3rd: for Thromboprophylaxis: Warfarin
2ndary causes of Pulmonary Hypertension
1) COPD
2) Mitral Stenosis
3) Systemic Sclerosis (Scleroderma)
4) L–>R shunt (ASD/VSD)
5) Sleep Apnea or High altitude
6) Recurrent Thromboembolism
First step in Diagnosing Pulmonary Hypertension
Echo and Swan Ganz Catheter (shows RVH and high PAP)
Besides ECHO and Swan Ganz Cath- Other diagnostic findings in Pulmonary Hypertension
EKG-Rt axis deviation, evidence of RVH and RA enalrgement
Labs-polycythemia
Common respiratory conditions in HIV patients
1) CD4<50 Mycobacterium Avium-intracellulare
3) CMV - intranuclear inclusion bodies
4) Aspergillosis fumigatus-pleuritic pain, hemoptysis, infiltrates on imaging
only 2 rx that are proven to reduce MORBIDITY and MORTALITY in COPD patients:
1) O2 therapy (if o2 sat<60 w/ cor pulmonale)
2) Smoking Cessation
