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 of white patches (i.e. pus). There may be enlarged and tender neck cervical lymph nodes.

Tonsillitis may be caused by Group A streptococcal bacteria, resulting in strep throat. Viral tonsillitis may be caused by numerous viruses such as the Epstein-Barr virus (the cause of infectious mononucleosis) or the Adenovirus.

Sometimes, tonsillitis is caused by a superinfection of spirochaeta and treponema, in this case called Vincent's angina or Plaut-Vincent angina.

Although tonsillitis is associated with infection, it is currently unknown whether the swelling and other symptoms are caused by the infectious agents themselves, or by the host immune response to these agents. Tonsillitis may be a result of aberrant immune responses to the normal bacterial flora of the nasopharynx.

Treatments of tonsillitis consist of pain management medications and lozenges. If the tonsillitis is caused by bacteria, then antibiotics are prescribed, with penicillin being most commonly used. Erythromycin is used for patients allergic to penicillin.

In many cases of tonsillitis, the pain caused by the inflamed tonsils warrants the prescription of topical anesthetics for temporary relief. Viscous lidocaine solutions are often prescribed for this purpose. Ibuprofen or other analgesics can help to decrease the edema and inflammation, which will ease the pain and allow the patient to swallow liquids sooner.

When tonsillitis is caused by a virus, the length of illness depends on which virus is involved. Usually, a complete recovery is made within one week; however, some rare infections may last for up to two weeks. Chronic cases may indicate tonsillectomy (surgical removal of tonsils) as a choice for treatment. Additionally, gargling with a solution of warm water and salt may reduce pain and swelling.

HUMAN BONE STRUCTURE - LESSON 200

-
Now in this post we will learn about the structure of the bone. In our human body there are 206 bones of different types are there. The thigh, lower leg, and upper and lower arm consists of long bones. These bones have large surface areas for muscle attachment and are very strong, are broad at the ends where they join with other bones. There are five types of bones in the human body. The five types are long, short, flat, irregular, and sesamoid. 1. Long bones:- These bones are comprised mostly of compact bone and lower amounts marrow, which is located within the medullary cavity, and spongy bone and are characterized by a shaft, the diaphysis, that is much larger in length than breadth. These bones are mostly present in the limbs, including those of the fingers and toes are long bones. Except the wrist, ankle, and kneecap these long bones are located in most. 2. Short bones:- These short bones are generally cube shaped and having a thin layer of compact bone surrounding a...

Palliative- Means just soothing or painkilling, not curing completely that is not possible. 6. PET scan or positron emission tomography- Radioactive materials are administered using intravenous route and these substances give out positrons. They generate a cross-sectional picture of the metabolism of the body. These images symbolize local concentration of the radio...

Today, we will know about an interesting medical term in medical language. This post is just to know about a different thing in the medical language, though this word is used very rarely in our day-to-day medical transcription work. The longest medical word is "Pneumonoultramicroscopicsilicovolcanoconiosis"!!!!!. Can you read at least Pneumonoultramicroscopicsilicovolcanoconiosis.  Now, we will see the meaning of this word.  To know the meaning shall we split the word by word. Okay.  1.  Pneumono 2.  Ultramicrosopic 3.  Silico 4.  Volcano 5.  Conosis. So, Pneumonoultramicroscopicsilicovolcanoconiosis comprises of 5 medical words and in combination, they give a meaning of a certain kind of disease condition related to lungs.  Now, we will see the meaning of each to get the combined understanding of the longest medical word. Pneumono means lungs, ultramicroscopic - means minute, silico means silicon, volc...
