|
How does a TIA differ from a stroke?
|
TIA: brief episode of neurologic dysfn caused by focal brain or retinal ischemia.
Clinical syx lasting less than one hour No e/o acute brain infarction Stroke: focal (or at times global) neurological impairment of sudden onset, and lasting more than 24 hours (or leading to death), and of presumed vascular origin |

|
Age
Smoking HTN Hyperlipidemia |
|

|
Describe the evaluation and management of a patient with stroke.
|
Emergency CT scan:
if hemorrhage, contraindication for tPA Checks if tumor Checks for early signs of infarct tPA should be given within 3 hours of syx; administration should not be delayed while awaiting results unless: -clinical suspicion of bleeding abnlty or thrombocytopenia -patient has received heparin or warfarin -use of anticoagulants not known |
|
Describe secondary prevention for non-cardioembolic stroke/TIA.
|
Daily ASA or ticlopidine/clopidogrel if ASA-sensitive

Breast milk is by far the most readily digestible, efficient, and healthy food for the baby. Switching to formula does not help.
Note: Simethicone to eliminate gas, or dicyclomine to slow down activity of gut; neither have been proven to work or be safe enough for infants. |
