Tuberculosis

Tuberculosis (TB) is a highly contagious bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs, but can also affect other parts of the body such as the lymph nodes, bones, and brain. It is a serious condition that can lead to severe health problems if left untreated. In this article, we will discuss the causes, symptoms, and treatments for tuberculosis, as well as ways to prevent the spread of this infection.

Causes of Tuberculosis

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. The bacteria is spread through the air when an infected person coughs, sneezes, or speaks. The bacteria can also be spread through contact with infected bodily fluids or tissues. People who have a weakened immune system, such as those with HIV or AIDS, are at an increased risk of developing tuberculosis.

Symptoms of Tuberculosis

Symptoms of tuberculosis can vary depending on the location of the infection. In the lungs, symptoms may include a persistent cough, chest pain, shortness of breath, coughing up blood, and weight loss. Other symptoms can include fever, night sweats, and fatigue.

Diagnosis and Treatment

Diagnosis of tuberculosis is typically made through a combination of a physical examination, chest X-ray, and a skin or blood test. Treatment for tuberculosis typically involves a combination of antibiotics, usually isoniazid and rifampin, for a period of six to nine months. It is important to follow the full course of treatment as prescribed by your doctor, even if symptoms improve before the medication is finished.

Prevention

The best way to prevent tuberculosis is to get vaccinated with the Bacillus Calmette-Guérin (BCG) vaccine. The vaccine is not recommended for adults, but is given to infants and children in some countries where the disease is common.

In addition to vaccination, it is also important to practice good respiratory hygiene, such as covering your mouth and nose when you cough or sneeze, and avoiding close contact with people who have active tuberculosis.

Multidrug-Resistant Tuberculosis (MDR-TB)

Another form of TB that is becoming increasingly common is multidrug-resistant tuberculosis (MDR-TB), which is caused by bacteria that are resistant to at least isoniazid and rifampin. MDR-TB is harder to treat and requires a longer course of treatment with more expensive and potentially toxic drugs.

Treatment of MDR-TB is complex and requires close monitoring by a healthcare professional. It's important to detect and treat MDR-TB as early as possible to prevent the spread of the disease and to prevent the development of extensively drug-resistant tuberculosis (XDR-TB).

Conclusion

Tuberculosis is a highly contagious bacterial infection caused by Mycobacterium tuberculosis that primarily affects the lungs but can also affect other parts of the body. It is a serious condition that can lead to severe health problems if left untreated. Symptoms of tuberculosis can vary depending on the location of the infection and include a persistent cough, chest pain, shortness of breath, coughing up blood, and weight loss. Diagnosis and treatment typically involve a combination of antibiotics for a period of six to nine months. The best way to prevent tuberculosis is to get vaccinated with the Bacillus Calmette-Guérin (BCG) vaccine and to practice good respiratory hygiene. Another form of TB that is becoming increasingly common is multidrug-resistant tuberculosis (MDR-TB) which is harder to treat and requires close monitoring by a healthcare professional.

What is myopia?

Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...
