It is important to realize that some medical conditions can mimic the symptoms of generalized anxiety disorder, for example hyper- or hypothyroidism, hypoglycaemia, drug or alcohol withdrawal and cardiac arrhythmias. Anxiety and fear are both associated with general arousal of the CNS and may be due to over activity in the RAS. Neurotransmitters in the RAS are serotonin and GABA.

Prostaglandins play a role in inflammation by causing vasodilation and increased vascular permeability and in pain by sensitizing sensory nerve endings to the effects of other mediators such as bradykinin. Thromboxanes promote platelet aggregation. Prostacyclin is produced from arachidonic acid in undamaged endothelium of blood vessels and plays a role in preventing unnecessary blood clotting. Inhibition of COX by NSAIDs reduces rather than abolishes inflammation because the drugs do not inhibit production of other mediators of inflammation.

Resistance to antimalarial drugs is now common. The most severe form of malaria is caused by Plasmodium falciparum and can be fatal. Fever occurs every third day due to rupture of infected red blood cells.

Diarrhoea can have a similar effect. The effectiveness of oral contraceptives can be reduced in this way. Certain drugs are excreted via expiration; the rate of excretion depends on plasma concentration, alveolar air concentration and blood-gas partition. Anaesthetic gases are the only group of drugs that are significantly excreted in expired air.

The nephron is the basic structural and functional unit of which there are about one million in each kidney. It is a blind ending tube, which begins with the Bowmans capsule. The Bowmans capsule is the dilated closed end that surrounds the knot of capillaries known as the glomerulus.

Pathological features of Alzheimers disease are extracellular plaques of β-amyloid protein and neurofibrillary tangles.
