HERNIA-A MEDICAL TRANSCRIPTIONIST MUST KNOW-1-LESSON 37

-

In this lesson we will study about hernia in detail. This term is used often in medical transcription while doing files. 
HERNIA:  Hernia is a protrusion or bulging forth, of an organ or the muscular wall of an organ through the cavity that normally contains it. The hernia has three parts: the orifice through which it herniates, the hernial sac, and its contents.

CHARACTERISTICS OF HERNIA: 
1. Congenital or acquired: congenital hernias occur prenatally or in the first year(s) of life, and are caused by a congenital defect, whereas acquired hernias develop later on in life. However, this may be on the basis of a locus minoris resistentiae (Lat. place of least resistance) that is congenital, but only becomes symptomatic later in life, when degeneration and increased stress (for example, increased abdominal pressure from coughing in COPD) provoke the hernia.

2. Complete or incomplete: for example, the stomach may partially herniate into the chest, or completely.
3. Internal or external: external ones herniate to the outside world, whereas internal hernias protrude from their normal compartment to another (for example, mesenteric hernias).
4. Intraparietal hernia: hernia that does not reach all the way to the subcutis, but only to the musculoaponeurotic layer. An example is a Spigelian hernia. Intraparietal hernias may produce less obvious bulging, and may be less easily detected on clinical examination.

5. Bilateral: in this case, simultaneous repair may be considered, sometimes even with a giant prosthetic reinforcement.

6. Irreducible (also known as incarcerated): the hernial contents cannot be returned to their normal site with simple manipulation. If irreducible, hernias can develop several complications (hence, they can be complicated or uncomplicated):

7. Strangulation: pressure on the hernial contents may compromise blood supply (especially veins, with their low pressure, are sensitive, and venous congestion often results) and cause ischemia, and later necrosis and gangrene, which may become fatal.

8. Obstruction: for example, when a part of the bowel herniates, bowel contents can no longer pass the obstruction. This results in cramps, and later on vomiting, ileus, absence of flatus and absence of defecation. These signs mandate urgent surgery.

9. Dysfunction: another complication arises when the herniated organ itself, or surrounding organs start dysfunctioning (for example, sliding hernia of the stomach causing heartburn, lumbar disc hernia causing sciatic nerve pain, etc.).

1. Magnetic resonance imaging- A magnetic ground radio signals are used to outline sagittal, coronal, and axial pictures of the body. 2. Megavoltage- High-energy radiation engendered by means of an equipment and employed in restorative x-ray analysis intended for cancer. 3. Nuclear medicine- This is a medical speciality, which examines and employs of radioactive materials called radionuclides within identification and treatment of ailment. 4. Orthovoltage- Emission of low-energy radioactive waves that are employed in pain-killing radiation therapy and exterior skin cancer diseases. 5. 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

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

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, volcano means eruption, and conosis means abnorm
