Major and minor criteria for risk of asthma
Major Criteria: Parent with asthma or personal history of atopic dermatitis
*Having 1 major criteria greatly increases the chance the child does or will have asthma
Minor Criteria: Maternal history of atopic disease or allergic rhinitis or >4% eosinophilia or Hx of wheezing not associated with URI
*Having 2 minor criteria also increases the chance the child does or will have asthma
When do you start screening for thyroid disease
w/ TSH beginning at 35 y/o and every 5 years after
How do you dx Cushing’s Syndrome and differentiate the causes of Cushing’s syndrome
Screening:
- LD Dexamethasone Suppression Test
- No suppression= Cushing’ Syndrome - 24 hour urinary free cortisol levels
- Elevated urinary cortisol = Cushing’s Syndrome - Salivary Cortisol levels
- Increased cortisol = Cushing’s Syndrome
Differentiating Test for causes of Cushing’s Syndrome
- HD Dexamethasone Suppression Test
- Suppression= Cushing’s Disease
- No suppression = adrenal or ectopic ACTH producing tumor
