ABC of Medical Emergency
Airway
Breathing
Circulation
CUSHING SYNDROME
- Cushing Disease: ACTH secreting tumor in pituitary
- Small cell carcinoma of the lung: ACTH production
- Adrenal gland adenoma/carcinoma
- Iatrogenic (exogenous)
CORTISOL INSUFFICIENCY
- Waterhouse Friderichsen Syndrome: Neisseria meningitis
- Stress in chronic adrenal insufficiency
- cold turkey steroids
- Addison disease (caused by autoimmune, tuberculosis, AIDs, fungal infections, metastatic cancer (lung
& breast) and systemic conditions.
- pituitary/hypothalamic tumor/infarction/trauma
- Adrenal crisis
HYPERTHYROIDISM
- Graves disease: autoantibodies bind to TSH receptors & stimulate thyroid hormone production outside
of TRH/TSH
, - Toxic multinodular goiter
- Toxic thyroid adenoma
HYPOTHYROIDISM
- Hashimoto Thyroiditis: chronic lymphocytic thyroiditis; immune response to thyroid antigens;
depletion of thyroid epithelial cells associated with lymphocytic infiltrates (B & T cells) and fibrosis;
increases risk for b-cell lymphoma.
- Myxedematous crisis: invasive surgical procedures in a hypothyroid patient can cause this
thyroxine (T4) --- levothyroxine - T4
triiodothyronine (T3) --- liothyronine - T3
Got it.
What lab values (within 6 months) should we consider which will generally dictate whether we can
perform dental treatment or not? (2)
*in regard to HIV/AIDS
Absolute Neutrophil Count (ANC)
Platelet count
Which other lab values will help us assess patient's current health status but DO NOT dictate whether
we can perform dental treatment? (2)
*in regard to HIV/AIDS
CD4 count
Viral load
*According to the CDC, which of the following is considered an AIDS diagnosis?
A. HIV+ with CD4+ T cell count of >200/mm3
B. HIV+ with CD4+ T cell count of <200/mm3
C. HIV- with CD4+ T cell count of >200/mm3
D. HIV- with CD4+ T cell count of <200/mm3
B. HIV+ with CD4+ T cell count of <200/mm3
*however, there are other ways of diagnosing AIDS
Once HIV infection is established then one of 3 things can diagnose AIDS.
Name the 3 diagnostic items
**1. CD4+ T-Cell count less than 200/mm3
