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!

Diverticulosis refers to a serious medical condition when pouches develop on the walls of your colon,which is another name for the large intestine. These pouches are small in size and usually vary from 5 to 10 millimeters, but can get bigger when this condition becomes serious. Diverticulosis is usually discovered while performing tests for other medical conditions on your body. Once these pouches become infected and inflamed, they may cause acute pain in your abdomen. This condition is called diverticulitis and is considered quite serious.

Causes of Diverticulosis:
Doctors have suggested that the pouches in diverticulosis are formed when pressure increases inside the colon and presses against the weaker spots in the walls of the large instesine. The differences in pressure may create tears or pouches within the colon resulting in the disorder. Some of the causes are mentioned here:

Low fiber diet: Low fiber diet causes small hard stool which makes it tough for the colon to put much more pressure. Low fiber diet can also increase the amount of time stool stays in the bowel which adds to high pressure and thus may contribute to this condition.
Age: The chances of diverticulosis increases when you are above the age of 60 which has something related to the weakening of bowels over time. A bad diet over many years can make this worse.
Lifestyle: Certain lifestyle habits which generally contribute to bad colon health may also result in diverticulosis by increasing pressure on the blood vessels of the bowel wall. This then pushes against other vessels resulting in the formation of pouches.
Diagnosis
Many people with diverticulosis may not even know they have this issue until it is detected while looking for other issues within the body. There are many cases when diverticulosis has been diagnosed when various tests like X-ray which use barium enema or colonoscopy is performed on your body for other medical reasons. If your white blood cells are higher in count than normal then it can indicate infection which may turn into diverticulitis. You may also be asked to undergo CT scan to check if the pouches are infected.

Symptoms of Diverticulosis:
Diverticulosis is hard to diagnose as it may not show any symptoms at all. In most cases symptoms start showing when it progresses towards diverticulitis. However certain generic symptoms which may prompt the doctor to require a detailed examination are as follows:
1. Diarrhea
2. Vomiting
3. Bloating or gas
4. Loss in appetite
5. Constipation

Treatment can be done at home or you may be asked to stay in hospital depending upon the severity of the case. Proper bed rest and liquid diet may be prescribed to enable the diverticula to heal properly.

Pouches In Large Intestine - Know the Reasons Behind it!

A headache can be a hindrance to any person at any time. It can either occur on left or right side in case of a migraine, be isolated to a point or radiate across the entire head. The pain can be sharp, throbbing or dull. It can either develop gradually or suddenly and can last for few hours to several days. Headaches need not arise due to a factor or condition of or in the head alone, they can be triggered because of other disorders or diseases in the body.

What are the different causes of a headache?
There are different kinds of headaches. Based on the symptoms, a doctor can diagnose the causes and the best treatment option for it. Not all headaches indicate serious illness. On the other hand, some headaches can be life-threatening as well. Primarily headaches can be divided into two broad categories- a primary headache and secondary headaches.

Primary headaches: A primary headache is caused due to conditions or factors associated with the pain-sensitive structures of the head. These types of headaches do not result from underlying illness. Muscles of the neck and head, blood vessels and chemical activity in and around the skull are the reason for primary headaches. Even certain genes could be responsible for triggering the pain. Some of the types of primary headaches include a cluster headache, tension headache, migraine, paroxysmal hemicrania etc. There could be primary headaches that last for a very long time such as sex headaches, cough headaches, chronic migraine, hemicranias continua etc. Typically, primary headaches are often triggered by poor posture, alcohol, lack of sleep, irregular food timings, processed meats etc.
Secondary headaches: Secondary headaches are the symptoms of a disease that can activate the pain-sensitive nerves of the head. The severity of the pain varies greatly. Some of the possible causes of secondary headaches include arterial tears, acute sinusitis, brain aneurysm, brain tumour, dehydration, ear infection, carbon monoxide poisoning, dental problems, glaucoma, hangovers, flu, hypertension, stroke, panic attacks, toxoplasmosis, post-concussion syndrome, trigeminal neuralgia, monosodium glutamate, meningitis, giant cell arteritis etc. Some of the common triggers of secondary headaches include ice cream headaches, compression headaches, thunderclap headaches, sinus headaches, rebound headaches, spinal headaches etc.
When to seek emergency care for headaches?
Headaches could indicate serious disorders such as encephalitis, stroke or meningitis. It is advisable to seek immediate medical care for an unbearable headache which also includes the inability to understand speech, stiff neck, trouble in vision, vomiting accompanied with nausea, trouble in speaking, high body temperature, greater than 104 F. A doctor should be consulted if the pain occurs multiple times in a short duration, keeps one from working or performing daily activities, the pain doesn t improve even after the consumption of over the counter medicine and disturbs sleeping.


Headache - Why You Must Consult For It?

There are two primary factors that are more likely to cause a stroke in a person i.e age and a family history. While both are inevitable, this necessarily doesn t have to be the fate of a person. Brain stroke is entirely preventable as with the case of other diseases. By working on the potential health risk factors, a stroke can be prevented. Here is a list of few such steps which, when followed can pay rich dividends to a person facing the risk of a brain stroke:

Blood Pressure: Blood pressure is the single most important factor that can increase the chance of a brain stroke. If a perfect blood pressure reading seems too difficult to achieve, a more realistic blood pressure target of 140/190 should be aimed for. Some of the common steps in order to achieve an acceptable blood pressure figure include reducing salt in the diet, exercising on a daily basis, regular intake of fresh fruits & vegetables and fast processed food containing processed fats. Finally, quitting drinking and smoking goes a long way in ensuring that a person is safe from strokes.

Losing Weight: Obesity increases the risk of diabetes and blood pressure subsequently increasing the risk of a stroke. Being overweight, therefore greatly increases the odds of a stroke. A BMI of 25 should be maintained by engaging in activities such as walking, running and playing on a daily basis.

Regular Exercise: Exercise is a clear mandate for people facing an increased risk of brain strokes. A moderate intensity exercise schedule for a minimum of 5 days per week is necessary. Some simple steps in order to achieve this include taking the stairs while climbing, joining a fitness club, 30 minutes of daily walk in a day etc.

Moderate Drink: Surprising as it may sound, moderate drinking on a daily basis can dramatically reduce the risk of a brain stroke. Red wine should be the choice of preference in this case. It should be ensured that the level of drinking does not surpass more than a glass. Regular drinking in excessive quantity can increase the chance of brain stroke.

Check For Atrial Fibrillation: This is a disease that is related to the heart due to an irregular heartbeat. There is a possibility of the clots travelling to the brain causing a brain stroke. Certain possible symptoms of this disease such as palpitation of heart and shortness of breath should be checked with a doctor to negate the chance of brain stroke. Certain blood thinners like warfarin and aspirin can shield against atrial fibrillation. A doctor has to be consulted before starting any medication related to the heart.

Top Ways To Prevent A Brain Stroke

Most people listen to music or their favourite videos while on the move, and they spend a considerable amount of time plugging in the headphones or earphones. If you are concerned about the pros and cons of the headphones and earphones, or rather which one is better, you will have to consider various aspects. These include noise isolation, frequency response, noise cancellation and comfort of wearing.

Earphones are devices which are worn on the pinna or the internal part of the ear. This device is also referred to as earbuds, in-ears, canal phones, buds, in-ear headphones, IEMs.

Headphones are equipment worn on or around the ear. These are not considered as handy as the earphones and are also known as ear speakers. Let s evaluate the pros and cons of these two devices and choose the one that is better.

Frequency response curve: This helps in assessing how much distortion is brought about by the devices which relate to the clarity. They should be able to respond equally well to all the pitches without transmitting any frequency more loudly than another. This suggests that the frequency you are receiving should be exactly similar to what has been fed in regardless of the frequency ranges. Typically, the earphones have bad frequency response while the headphones tend to have better frequency response. If you are primarily concerned about the noise distortion, then you should opt for headphones.
Noise isolation: By this, it is understood how well does the gear help in isolating other noises than what you are trying to listen. Generally, higher noise isolation is preferred unless you are willing to hear the sounds of the ambience. Better isolation also ensures that your audio would not bother others surrounding you. A rightly fitted pair of earphones would be able to give you the best noise isolation whereas good over-ear headphones would not be able to seal the sound from going out.
Noise cancellation: Noise cancellation is entirely different from the noise isolation. In the process of noise isolation, the atmospheric sounds which intrude in are reproduced and inverted. This is an excellent feature especially when you are travelling through public transportation or walking down the street. When it comes to earphones, the noise cancellation feature is are not as effective as headphones unless you buy any of the high end pieces. But the headphones are far better in cancelling the noises that are constantly playing in the backdrop.
Judging from all these aspects, the headphones tend to be a better purchase than the earphones, and they are also much more comfortable. Still, it boils down to personal preference at the end. If you wish to discuss about any specific problem, you can consult a general physician.
