Tachypnea, also spelt tachypnoea, is a respiratory rate greater than normal, resulting in abnormally rapid and shallow breathing. [1]In adult humans at rest, any respiratory rate of 12–20 per minute is considered clinically normal, with tachypnea being any rate above that. [2]
Full-body hemihypertrophy. Hemihypertrophy, now more commonly referred to as hemihyperplasia in the medical literature, is a condition in which one side of the body or a part of one side of the body is larger than the other to an extent considered greater than the normal variation.
Alice in Wonderland Syndrome (AIWS), also known as Todd's Syndrome or Dysmetropsia, is a neurological disorder that distorts perception.People with this syndrome may experience distortions in their visual perception of objects, such as appearing smaller or larger (), or appearing to be closer or farther than they are.
A positive value indicates that the object was perceived bigger and thus corresponds to macropsia, and conversely a negative value indicates micropsia. [4] The Aniseikonia Inspector contains an aniseikonia test based on the same principles as the NAT, but the test is run on a computer screen, it is based on a forced choice method, and it can ...
During this transition, the body stops releasing estrogen at a faster rate than it stops releasing androgens. In some cases, the difference between the lower estrogen levels and higher androgen levels can produce hyperandrogenism. A decrease in sex hormone levels while the free androgen index increases can also contribute to this process. [51]
The body has several feedback mechanisms to maintain adequate blood flow and blood pressure. If blood pressure decreases, the heart beats faster in an attempt to raise it. This is called reflex tachycardia. This can happen in response to a decrease in blood volume (through dehydration or bleeding), or an unexpected change in blood flow.
The indication is an excess breast weight that exceeds approximately 3% of the total body weight. [3] There are varying definitions of what is considered to be excessive breast tissue, that is the expected breast tissue plus extraordinary breast tissue, ranging from as little as 0.6 kilograms (1.3 lb) up to 2.5 kilograms (5.5 lb) with most physicians defining macromastia as excessive tissue of ...
Hyperplasia is considered to be a physiological (normal) response to a specific stimulus, and the cells of a hyperplastic growth remain subject to normal regulatory control mechanisms. [5] However, hyperplasia can also occur as a pathological response, if an excess of hormone or growth factor is responsible for the stimuli.
