Magnetic resonance imaging
Magnetic resonance imaging (MRI) use has become increasingly common for diagnosis of appendicitis in children and pregnant patients due to the radiation dosage that, while of nearly negligible risk in healthy adults, can be harmful to children or the developing baby. In pregnancy, it is more useful during the second and third trimester, particularly as the enlargening uterus displaces the appendix, making it difficult to find by ultrasound. The periappendiceal stranding that is reflected on CT by fat stranding on MRI appears as an increased fluid signal on T2 weighted sequences. First trimester pregnancies are usually not candidates for MRI, as the fetus is still undergoing organogenesis, and there are no long-term studies to date regarding its potential risks or side effects. X-ray
In general, plain abdominal radiography (PAR) is not useful in making the diagnosis of appendicitis and should not be routinely obtained from a person being evaluated for appendicitis. Plain abdominal films may be useful for the detection of ureteral calculi, small bowel obstruction, or perforated ulcer, but these conditions are rarely confused with appendicitis. An opaque fecalith can be identified in the right lower quadrant in fewer than 5% of people being evaluated for appendicitis. A barium enema has proven to be a poor diagnostic tool for appendicitis. While failure of the appendix to fill during a barium enema has been associated with appendicitis, up to 20% of normal appendices do not fill. Scoring systems
Several scoring systems have been developed to try to identify people who are likely to have appendicitis.
Amlodipine-association edema can be avoided by adding ACE inhibitors or angiotensin II receptor antagonist. Of the other dose-dependent side effects, palpitations (4.5% at 10 mg vs. 0.6% in placebos) and flushing (2.6% vs. 0%) occurred more often in women; dizziness (3.4% vs. 1.5%) had no sex bias.Common but not dose-related adverse effects are fatigue (4.5% vs. 2.8% with a placebo), nausea (2.9% vs. 1.9%), abdominal pain (1.6% vs. 0.3%), and drowsiness (1.4% vs. 0.6%). Side effects occurring less than 1% of the time include: blood disorders, impotence, depression, peripheral neuropathy, insomnia, tachycardia, gingival enlargement, hepatitis, and jaundice.Amlodipine-associated gingival overgrowth is a relatively common side effect with exposure to amlodipine. Poor dental health and buildup of dental plaque are risk factors.Amlodipine may increase the risk of worsening angina or acute myocardium infarction, especially in those with severe obstructive coronary artery disease, upon dosage initiation or increase. However, depending on the situation, Amlodipine inhibits constriction and restores blood flow in coronary arteries as a result of its property that works directly on vascular smooth muscle causing reduction in peripheral vascular resistance and consequent reduction in blood pressure. Overdose
Although rare, amlodipine overdose toxicity can result in widening of blood vessels, severe low blood pressure, and fast heart rate. Toxicity is generally managed with fluid replacement monitoring ECG results, vital signs, respiratory system function, glucose levels, kidney function, electrolyte levels, and urine output. Vasopressors are also administered when low blood pressure is not alleviated by fluid resuscitation. Interactions
Several drugs interact with amlodipine to increase its levels in the body.
