Nondisplaced Tear. Fig. 2. Subcortical cysts and posterior capsular stripping in a 16-year-old male who had right shoulder pain when throwing for 3 months. (A) Subcortical cysts (arrow) in the greater tuberosity at the insertion of the supraspinatus tendon are seen as high signal intensity on a fat-suppressed T2-weighted image. (B) Axial gradient echo T2-weighted image shows a nondisplaced tear of the posterior labrum and capsular stripping (arrow). Fig. 3. Posterosuperior labral tear and impaction of the greater tuberosity in a 17-year-old female pitcher who had right shoulder pain and impingement for 5 years.
A key tool in this effort is the Air Quality Index, or AQI. EPA and local offi-cials use the AQI to provide simple information about your local air quality, how unhealthy air may affect you, and how you can protect your health.
NAPQI (N-acetyl-p-benzoquinone imine) is a toxic byproduct produced during the xenobiotic metabolism of the analgesic paracetamol (acetaminophen). It is normally produced only in small amounts, and then almost immediately detoxified in the liver.he prognosis is good for paracetamol overdoses if treatment is initiated up to 8 hours after the drug has been taken. Most hospitals stock the antidote (acetylcysteine), which replenishes the liver's supply of glutathione, allowing the NAPQI to be metabolized safely.
