Hepatitis C, Introduction to Hepatitis C

 

Introduction to Hepatitis C:

Hepatitis C is a liver disease which is caused by the hepatitis C virus (HCV): the virus can cause both acute and chronic hepatitis, ranging in severity from a mild illness lasting a few weeks to a serious, lifelong illness. Hepatitis C is a major cause of liver cancer.

It is a blood-borne virus: the most common modes of infection are through exposure to small quantities of blood. which may happen through injection drug use, transfusion of unscreened blood, unsafe injection practices, unsafe health care, and blood products and sexual practices that lead to exposure to blood. 

Worldwide, an estimated 71 million people are infected with chronic hepatitis C virus infection. A large number of those who are chronically infected will develop cirrhosis or liver cancer. WHO estimated that in the year 2016, approximately 399 000 people died from hepatitis C, mostly from cirrhosis and hepatocellular carcinoma (primary liver cancer). Antiviral medicines can cure more than 95% of persons with hepatitis C infection, by this reducing the risk of death from cirrhosis and liver cancer, but access to diagnosis and treatment is less. There is currently no effective vaccine against the hepatitis C virus.

Corona Virus COVID-19 SARS-CoV SARS-CoV2 Novel corona virus COVID Corona

COVID-19; Stand for  coronavirus disease in 2019 . The name COVID-19 was given by  WHO  on February 11 2020 to the disease caused by the novel coronavirus SARS-CoV2. The name SARS-CoV2 was given to it because this virus is a genetic cousin of coronavirus which caused the SARS outbreak in 2002 (SARS-CoV)  [1]. What is coronavirus? Coronaviruses are common human and animal  single-strand RNA genome  viruses belonging to the  family coronaviridae  that was first, discover in the 1930S in domestic poultry. In animals,  coronavirus causes a range of respiratory, gastrointestinal, and neurologic diseases.  In human  coronaviruses are mainly seven types that cause a range of diseases. A) Four human  coronaviruses cause symptoms of the common cold namely; 229E, OC43, NL63, and HUK1. B) Three human  coronaviruses cause much more serious lung infections, also called pneumonia. SARS-CoV in 2002  (severe acute respiratory syndrom...

lung cancer

Definition: The World Health Organization (WHO) defines lung cancer as tumors arising from the respiratory epithelium (bronchi, bronchioles, and alveoli). OR Lung cancer is a type of cancer caused by uncontrolled cell division of the respiratory epithelium (bronchi, bronchioles, and alveoli). Normal structure and function of the lungs: Lungs are 2 sponge, pyramid-like organs located in the chest. Each lung is divided into sections called lobes. The right lung has three lobes while the left lung has two lobes. The left lung is smaller than the right one because the heart on the left side takes up more room of the chest. When you inhale air through mouth and nose it enters into lungs through trachea (windpipe). The trachea divides into tubes called bronchi, which enter the lungs and divide into smaller branches called bronchioles. At the end of bronchioles there are small tiny sacs called alveoli. These alveoli absorb oxygen from the inhaled air into your b...

What is sutures? types of Sutures i:e Absorbable sutures and nonabsorbable sutures.

Sutures:  Sutures bind tissues together Sutures are used to hold skin, internal organs, blood vessels, and all other tissues after they have been severed by injury or surgery. Sutures are designed to help the healing of the body by closely opposing the two sides of a wound to minimize scar formation or to prevent leaking blood, like in vessels. They have to comply with several requirements to be effective. They must be strong (so they do not break), non-toxic and hypoallergenic (to avoid adverse reactions in the body), and flexible (so they can be tied and knotted easily). Also, they must lack the so-called "wick effect", which means that sutures must not allow fluids to penetrate the body through them from outside, which could easily cause infections. Sizes of Sutures:  Sizes of Sutures are sized according to the USP scale. Sizes and diameters are available on a scale from 6 to 0, which is 0.07 mm in diameter, to 2, which is 0.5 mm: 6-0 = 0.07 mm 5-0 = 0.10 mm 4-0 = 0....
