Premalignant, erythematous, scaly macules that occur on sun-exposed areas, primarily in older people
Actinic Keratoses

60-80%
Chronic inflammatory condition characterized by Central Facial erythema with transient papules/pustules

How to differentiate Obstructive disease process of Asthma vs. COPD based on PFTs
In COPD the DLCO will be on the lower end of Normal or decreased
In Asthma the DLCO will be on the upper limit of normal or Increased
Tense blisters, non-pruritic in sun-exposed areas. Hyperpigmentation
Stem may describe patient who has Hep C or is Alcoholic or has Hemachromatosis
Decreased Urophyrinogen decarboxylase leads to increased Uroporphyrinogen deposition in the skin
Screening: Urine will show increased uroporphyrinogens
Treatment: Phlebotomy or anti-malarial drugs
Name a possible cause of the following PFTs
Patient 1:
FEV1: Decreased
FEV1/FVC: Normal
TLC: Decreased
DLCO: Decreased
RV: Decreased
Patient 2:
FEV1: Decreased
FEV1/FVC: Normal
TLC: Decreased
DLCO: Normal
RV: Increased
Low TLC = Restrictive
Causes of Intrathoracic restrictive dz will have a decreased DLCO and low RV (Pulmonary Fibrosis, Sarcoidosis, Pneumoconiosis)
Causes of Extrathorasic restrictive dz will have a Normal DLCO with an increased RV (severe Kyphosis, Neuronmusclar disorders (MG, GBS)
