Tuberculosis or TB is a highly contagious airborne disease, which is caused by Mycobacterium tuberculosis. It typically affects your lungs and is characterized by the formation of greyish, hard nodules or tubercles.

Pathology of Tuberculosis

Diagnosis of the disease depends essentially on identifying the bacteria from the tissue. Methods of diagnosis usually include the following  

Skin Test   The most common test for detection of tuberculosis is the skin test. During the procedure, a small dose of PPD tuberculin is injected onto the skin of the forearm. The injection site needs to be monitored after a couple of days. Swelling in the forearm, usually, a hard, red bump could mean that you have contracted tuberculosis.
An X-ray of the Chest   Chest X-ray can reveal calcification, cavitations, and nodes in the upper lobes
Sputum Cultures and Smears   These are mostly used to detect pulmonary tuberculosis. Three specimens of sputum early in the morning are collected on three separate days. The specimen is prepared on a slide and stained with an acid-fast dye before being observed under the microscope. The slide may show the characteristic AFB or acid-fast bacilli.
Gastric Aspirates Test   This involves placing a tiny nasogastric tube in the abdomen early in the morning and gastric contents are suctioned and processed for culture and smears.
Lymph Node Biopsy   The procedure involves removing an enlarged lymph node and culturing a portion of it. The remaining section is sent for staining and examined under a microscope.
Biopsy   Biopsy is conducted when an abnormality develops in the airways during bronchoscopy. This involves threading a thin wire through the bronchoscope and attaching tiny biopsy forceps to its end in order to remove multiple tissue samples from the bronchi. The samples are sent to the laboratory for complete analysis.
Treatment of Tuberculosis

Studies show that in the majority of cases, patients were cured with the help of the right medication. The type and dosage of antibiotic treatment precisely depend on factors like   the patient s age, health condition, and potential resistance to certain drugs, whether the disease is active or latent, and the infection site.
Patients with latent TB may require one type of antibiotic, while those having active TB   particularly MDR TB   are often prescribed multiple drugs for about 6-9 months.
Patients who received proper treatment on time have shown vast improvement on the health aspect. After a few weeks of undergoing treatment, you might be tempted to quit taking your TB medications, but it is important that you complete the full treatment course. Skipping doses may allow the bacteria to become drug-resistant, leading to tuberculosis that is more severe and difficult to cure.



Tuberculosis - All You Must Know!

Tuberculosis is an airborne communicable disease that mainly affects the lungs. However, it can attack the other organs as well. A tuberculosis infection may be categorised as latent or clinically active. A person is said to be suffering from latent tuberculosis when he or she has been infected with the tuberculosis bacteria, but is protected from the germs by a strong immune system. People showing symptoms of the disease are said to be suffering from a clinically active form of tuberculosis and must seek medical attention as soon as possible.

The symptoms of tuberculosis may be hard to identify as they can be attributed to other causes as well. In some cases, the symptoms may not appear until the disease has reached an advanced stage. Some of the common symptoms associated with this disease are:

Weight loss
Fever
Dry cough
Excessive sweating at night
Unexplained tiredness
Poor appetite
Chest pain
People with a weakened immune system such as those suffering from HIV or those undergoing chemotherapy have a high risk of suffering from this condition. When the disease is in its active form, tuberculosis causing bacteria multiply rapidly and attack the lungs. From here they may spread to other parts of the body, such as the lymph nodes, kidneys, bones, spine, brain and skin. When it reaches an advanced stage, the symptoms vary according to the organ affected. For example, pain in the bones indicates that the bone tissues have been affected while coughing up blood is a sign of TB of the lungs.

Tuberculosis can be diagnosed through a blood test or with a skin test. An x-ray and a lab analysis of your sputum can also help differentiate between latent and clinically active forms of this disease.
In the case of latent infections, preventive therapy is prescribed to kill the germs before they become active. This typically takes the form of a single tablet that must be taken for six to nine months.

Clinically active tuberculosis can be easily treated and cured as long as the patient undergoes the complete course of treatment. Treatment for this disease usually takes the form of oral medication that must be taken for six to nine months continuously. This is because tuberculosis causing bacteria can take a very long time to die. In some cases, multiple drugs may be prescribed to reduce resistance to the drugs. When it comes to tuberculosis it is important to continue taking medication for its full course, even if the symptoms disappear and you are feeling better. 

7 Signs You Are Suffering From Tuberculosis!

Bronchial asthma is a medical condition. It happens when the airways of your lungs swell up and become narrow. This limits the amount of air that can pass through the passages and this leads to respiratory distress. Asthma can affect anyone and usually, it starts from childhood.

What are the Symptoms of Bronchial Asthma?
Some common symptoms of bronchial asthma are-

  Wheezing and breathlessness
  Tightness of the chest
  Frequent bouts of coughing which are more common at night or in the early morning, making sleep difficult. 

Bronchial asthma does not go away on its own. It requires treatment.

What is Siddha?
Siddha is a very ancient system of medication and treatment that originated in Tamil Nadu. According to Siddha, the individual is a microcosm of the entire universe. And it is made up of some fundamental elements- earth, air, fire, water and ether as well as three humours- Vata, Pitta and Kapha. An imbalance of these components causes an ailment. So, the chief goal of Siddha is to restore the right balance to root out any illness.

Types of Asthma according to Siddha -
We find mention of asthma in Siddha literature. It is called Eraippu Noi. There are five types of asthma -

  Vazhi Eraippu Noi - Digestive troubles may lead to accumulation of Vata. This is not a grave form of asthma and can easily be cured.

  Iya Eraippu Noi - Exposure to cold climes or freezing winds or being drenched in rain can cause Kapha to build up in the system, which triggers this form of asthma. It is accompanied by symptoms such as the runny nose, nasal congestion, breathing trouble when lying down.

  Iyavazhi Eraippu Noi - Both Vata and Kapha accumulate to trigger this kind of asthma. Its symptoms include breathlessness, bloating, indigestion, disorientation, etc.

  Mukkuttra Eraippu Noi - An imbalance of all three humours- Vata, Pitta and Kapha are the culprits behind mukkuttra Eraippu Noi. A person who has contracted it might experience severe chest pain, constipation and even loss of consciousness.

  Mel nokku Eraippu Noi - This is the gravest form of bronchial asthma and requires extensive treatment.

Treatment of Asthma according to Siddha -

Siddha will first try to understand what kind of imbalance has caused your asthma. The medication depends on the type of asthma. Siddha medicines are made from particular parts of herbs that will induce you to either vomit or defecate to get rid of the excess humour that has accumulated in your body. Thus, the balance of Kapha, Pitta and Vata is restored.

You might also be suggested a few breathing exercises to strengthen your lungs and diaphragm.
Siddha follows a holistic way to curing bronchial asthma and targets it at its source. Unlike allopathic medication, medicines prescribed by Siddha are herbal and have no side effects.

Siddha Approach In Treating Bronchial Asthma!

If you are suffering from bronchitis, it is important for you to recognize whether your condition is acute or chronic in nature. Bronchitis is a condition that involves the inflammation of the airways between your lungs and the windpipe. The lining of these tubes produces mucus in large amounts that trigger a lingering cough.

Acute bronchitis is the form of bronchitis that onsets rapidly after a virus infection in your upper respiratory tract. The viruses that cause common cold or influenza, are also responsible for acute bronchitis. Moreover, the germs that are responsible for measles and whooping cough may lead to acute bronchitis. In such cases, the condition is referred to as acute infectious bronchitis. In case of dust, smoke, or fumes causing bronchitis, it is referred to as acute irritative bronchitis.

Diagnosis

For the diagnosis of acute bronchitis, you will be inquired about the symptoms you are experiencing.
After that, an overall and detailed physical examination is carried out, which confirms acute bronchitis.
In some cases, the patient might have to get an X-Ray done for ruling out other conditions such as pneumonia.
Treatment
Generally, in about two weeks, acute bronchitis resolves on its own without any medical treatment.
Medications: Several medications may be prescribed for the treatment of acute bronchitis.

Antibiotics: These are usually not used for treating bronchitis, as the condition occurs from a viral infection. However, when you have a bacterial infection, antibiotics may be useful for treating it.
Cough medicine: It is recommended for you not to suppress cough bringing up mucus, as the coughing helps in removing irritants from the lungs and air passages. In case of cough that hampers your activities, you may take cough suppressants before going to sleep at night.
Other medications: In case you have allergies, or suffer from asthma or chronic obstructive pulmonary disease (COPD), an inhaler along with other medications may be recommended for the reduction of inflammation, and for opening the narrowed passages within your lungs.
Prevention

Quit smoking immediately and try to keep away from secondhand smoke.
Keep yourself clean and hygienic during the flu season.
Try to avoid direct contact with people who are sick or infected.
Get a flu vaccine on a regular, yearly basis.
Drink a lot of fluids throughout the year.
Consider using a warm or cool, moist air humidifier for helping to thin the mucus layers blocking your air passages.
It is important for you to consult a doctor on experiencing any symptom of acute bronchitis. This will allow timely diagnosis and treatment, and prevent the condition from worsening.

World TB Day Special - How to Prevent Tuberculosis

Tuberculosis is one of the most serious infectious diseases and can easily spread from one person to another when the virus enters the air through a sneeze or a cough. The disease is partly preventable by vaccines. It was once upon a time quite rare, but today has become quite common in urban areas. The emergence of HIV is one of the main reasons for this. HIV is an immune system disorder that weakens the body s ability to fight back against infections. With time, the virus causing the disease has evolved and become resistant to many drugs used to treat it.

Tuberculosis is also more commonly seen in slum areas of the cities. This is because of a lack of ventilation and living in close proximity that makes it easy for the disease to spread from one person to another. Limited access to safe drinking water and proper sanitation also reduces immunity and increases the risk of tuberculosis.

To control the spread of tuberculosis, it is important to treat it and keep away from other people while being treated. People also need to be made aware of the disease and its symptoms. It is important for the general public to understand that tuberculosis can be treated. They should also be informed that treatment of tuberculosis is free. As with most chronic diseases, the earlier treatment is started, the easier it is. 

Thus, if you notice any of the early symptoms of tuberculosis such as 

Weakness
Low fever 
Unexplained Weight loss
Then, you must consult a doctor immediately.

Tuberculosis can be diagnosed through a simple skin test or blood test. In terms of the skin test, the results can take up to 72 hours. It is important to note that this test is not foolproof as it can give a false positive or false negative result. For this reason, this may be followed by a blood test. Treatment for tuberculosis takes the form of oral antibiotics. The disease is no longer contagious after the medication is taken for a few weeks. 

However, taking the full course of medication is essential to stopping medication early can make the bacteria resistant to the drug. Tuberculosis caused by drug-resistant bacteria is much harder to treat.
Thus, to reduce the number of cases of tuberculosis in urban areas, people must be made aware of the disease and its treatment. Proper sanitation and ventilation in their living areas should also be provided.
