Slipping rib syndrome. Slipping rib syndrome (SRS) is a condition in which the interchondral ligaments are weakened or disrupted and have increased laxity, causing the costal cartilage tips to subluxate (partially dislocate). This results in pain or discomfort due to pinched or irritated intercostal nerves, straining of the intercostal muscles ...
The test is not infallible and many factors can cause the test to give false positive or negative results. Decomposition may result in postmortem gas formation, allowing a non-aerated lung to float. [2] During labor, air can be introduced to a deceased infant's lungs while moving through the birth canal. Lungs exposed to air do not always float ...
Twelfth rib syndrome. Twelfth rib syndrome, also known as rib tip syndrome, is a painful condition that occurs as a result of highly mobile floating ribs. It commonly presents as pain that may be felt in the lower back or lower abdominal region as a result of the 11th or 12th mobile rib irritating the surrounding tissues and nervous systems.
The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. [6] The false positive rate depends on the significance level. The specificity of the test is equal to 1 minus the false positive rate.
