Rett syndrome (RTT) is a genetic disorder that typically becomes apparent after 6-18 months of age and almost exclusively in girls. [4] Symptoms include impairments in language and coordination, and repetitive movements. [4]
Gormley and Brydges found that in a group of 800 adults, 17% of women and 9% of men reported difficulty differentiating between left and right. [6] Such studies suggest that women are more prone to LRC than men, [7] with women reporting higher rates of LRC in both accuracy and speed of response. [4] [8] [9]
Differentiation between a right-to-left shunt and pulmonary disease is often aided clinically by the results of a hyperoxia test. [citation needed] Using high levels of inspired oxygen should have little effect on the dissolved O2 in the blood because highly oxygenated blood is diluted by shunted (low oxygenation) blood.

Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst , leading to an insufficient number of oxygen-carrying red blood cells in circulation . The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in ...
Causes range from non-serious to potentially fatal. [1] There are three broad categories of causes: heart or blood vessel related; reflex, also known as neurally mediated; and orthostatic hypotension. [1] Issues with the heart and blood vessels are the cause in about 10% and typically the most serious while neurally mediated is the most common. [1]
The mean corpuscular volume or MCV is usually normal or low for congenital causes of sideroblastic anemia but normal or high for acquired forms. With lead poisoning, see coarse basophilic stippling of red blood cells on peripheral blood smear; Specific test: Prussian blue stain of RBC in marrow shows ringed sideroblasts.
Complex regional pain syndrome is a multifactorial disorder with clinical features of neurogenic inflammation (inflammation mediated by nerve cells), nociceptive sensitisation (which causes extreme sensitivity or allodynia), vasomotor dysfunction (blood flow problems which cause swelling and discolouration) and maladaptive neuroplasticity ...
