Tonsillits - Lesson 45

Tonsils are lymphatic tissue in the throat. They contain white blood cells (lymphocytes) and function to filter and fight bacteria, but they can also become infected and inflamed. Streptococcal infection of the throat can cause tonsillitis, which leads to the procedure of tonsillectomy. Tonsillitis is an infection of the tonsils and will often, but not necessarily, cause a sore throat and fever. There are 3 main types of tonsillitis: acute, subacute and chronic. Acute tonsillitis can either be bacterial or viral in origin. Subacute tonsillitis is caused by the bacterium Actinomyces. Chronic tonsillitis, which can last for long periods if not treated, is almost always bacterial. Symptoms of tonsillitis include a severe sore throat (which may be experienced as referred pain to the ears), painful/difficult swallowing, crouch coughing, headache, fever and chills. Tonsillitis is characterized by signs of red, swollen tonsils which may have a purulent exudativ coating

Ischemia - Lesson 43

In medicine, ischemia is a restriction in blood supply, generally due to factors in the blood vessels, with resultant damage or dysfunction of tissue. It may also be spelled ischaemia or ischæmia. Ischemia- Isch/o means hold back, -emia means blood from a part of the body. A tissue that becomes ischemic loses its normal flow of blood and becomes deprived of oxygen. The ischemia can be caused by mechanical injury to a blood vessel, by blood clots lodging in a vessel, or by the gradual closing off (occlusion) of a vessel owing to of fatty material. Rather than in hypoxia (less oxygen), a more general term denoting a shortage of oxygen (usually a result of lack of oxygen in the air being breathed), ischemia is an absolute or relative shortage of the blood supply to an organ. Relative shortage means the mismatch of blood supply (oxygen delivery) and blood request for adequate oxygenation of tissue. Ischemia results in tissue damage because of a lack of oxygen and nutrients
