Pulmonary Function Tests or PFTs are a set of tests that are used to determine, measure or observe the functioning of the lungs. The most common pulmonary function tests used are spirometry, gas diffusion, and lung plethysmography. 

Highlights of pulmonary function tests

A spirometry test is used to measure the amount of air inhaled and exhaled. It also measures the amount of time taken to complete a respiration cycle.
A lung plethysmography measures the amount of air in the lungs after the patient has taken a deep breath. It also measures the amount of air that remains in the lungs after the patient has exhaled as much air as possible.
What does a Pulmonary Function Test measure?
Pulmonary function tests would not only check how well the person is breathing but also how effectively the lungs are able to conduct oxygen to the rest of the body. In addition to air flow, these tests would measure the size and volume of the lung and lung diffusion.

These tests can also be used to measure

Total Lung Capacity   the amount of air present in the lungs after breathing in deeply
Forced Vital Capacity   the amount of air that can be exhaled after breathing in deeply
Minute Volume   the amount of air exhaled per minute
Vital Capacity   the total volume of air that can be breathed out after inhaling as much as possible
Tidal Volume   the amount of air inhaled or exhaled when breathing normally
Maximum voluntary ventilation   the amount of air that can be inhaled and exhaled in one minute
Functional Residual Capacity   the amount of air that remains in the lungs when breathing normally
Forced Expiratory Flow   the flow or volume of air during an exhalation
Peak Expiratory Flow Rate   the rate at which a person can exhale
When are Pulmonary Function Tests recommended?
A physician might recommend a patient undergo a PFT as part of a routine physical check-up. This test would be advised if the patient is experiencing any symptoms associated with lung problems or disorders such as asthma, respiratory infections, chronic obstructive pulmonary disease, COPD. A doctor would also use these tests to monitor and check whether a certain treatment prescribed for a lung disease or condition is working effectively.

Pulmonary function tests are safe as they are non-invasive but it is important to follow the instructions of the doctor or technician before, after and during the test. It is important to make your doctor aware of any surgeries, respiratory infections, chest pains or heart attacks that you might have experienced before the test. If you are taking any medications you might need to follow the advice of the doctor as to whether you can take them before the test.

Your doctor would also advice you on how to prepare for the test such as not eating a large meal, avoiding caffeine and wearing loose-fitting clothes. If you have any doubts, concerns or queries discuss them with your doctor.

Pulmonary Function Tests - Why Is It Required?

The inflammation of the kidneys as an effect of Systemic Lupus Erythematosus (SLE) is known as Lupus Nephritis. Like lupus, this is an autoimmune disease. Inflammation of the kidneys hinders kidney functioning by not allowing the kidneys to regulate the optimum amount and types of fluids in the body and restricts the removal of waste through urine. It can also cause the protein to leak out of the kidneys. If not managed in time, this can eventually lead to kidney failure by scarring the kidney tissue. However, this is a rare occurrence. 

On an average, 6 out of 10 lupus patients suffer from lupus nephritis. In most cases, this disease develops within the first five years of lupus symptoms making their appearance. The symptoms of this disease are mild and can vary from person to person. Very often, the first signs of lupus nephritis become visible only in lab tests as the symptoms are similar to those exhibited by other kidney diseases. 

Some of the common symptoms of this condition are: 

Swelling of the feet, ankles and calves 
High blood pressure 
Weight gain 
Frothy, dark urine 
There are five stages types of this disease and hence, the first step to treating this disease is to identify its type. For this, your doctor will begin with a thorough physical examination and understand your medical history. He or she will also ask for a few tests including urine tests, blood tests, an ultrasound and a kidney biopsy to confirm the diagnosis. 

Lupus nephritis is usually treated with corticosteroids and immunosuppressive drugs. Medication may also be prescribed to lower blood pressure and prevent the clotting of blood. However, in some cases, this treatment may not be enough to stop the progression of the disease and some kidney function may be lost. If both kidneys fail, dialysis is the next medical step. This involves the use of a machine in place of the kidneys to filter and removes waste products from the body. This may be followed by the need for a kidney transplant. 

Since lupus patients are at a high risk of lupus nephritis, here are a few conscious lifestyle changes that can help prevent this condition:

Have a diet that is low in salt 
Avoid smoking and alcohol 
Exercise regularly 
Avoid non-steroid anti-inflammatory drugs("pain killers") and unproven alternative medications that can affect the kidneys.

What Is Lupus Nephritis?

The infection of the bone of the ear is Mastoiditis. This may be an acute infection needing hospitalisation and injectable drugs or may be in the form of slow bone eroding processes like cholesteatoma.

Let us learn more about this condition and its treatment

Understanding the mastoid bone: The mastoid bone is made up of air sacs and it looks a lot like a sponge. In this sense, it is different from the other bones that can be found in the human body. In order to function properly, this bone requires air from the other parts of the ear, including the Eustachain Tube which connects the middle part of the ear with the portion that lies at the back of the throat. If this tube gets infected due to any reason, the infection and bacteria can also travel to the Mastoid bone, leading to an infection in this area. Another form of the infection starts from the ear drum and a slowly progressive bone eroding process starts which spreads into the air sacs and can potentially spread to the brain.

Symptoms: Acute mastoiditis will present with earache, ear discharge and onset of fever and chills, as well as redness and inflammation behind the ear. Pain in the ear may be experienced along with headaches and swelling that may be experienced behind the eyes. At the very earliest sign, these symptoms must be reported to an ENT or ear throat nose specialist so that the treatment can happen at the earliest. Chronic mastoiditis may be due to repeated infections and bone eroding cholesteatoma which presents with repeated episodes of ear discharge which may be foul smelling and may even have blood.

Diagnosis: The diagnosis is mostly made on ear examination and may involve imaging tests like a CT scan as well as an MRI scan of the head and the ear. A simple X-ray of the mastoids can help in detecting the severity of the infection, and it spread.

Treatment: After diagnosing the problem with imaging tests as well as a detailed ear examination, the doctor will usually start the treatment by admitting the patient in the hospital. Antibiotic medication will be administered through intravenous methods, after which oral antibiotics will be prescribed for many days after the patient has been discharged from the hospital. Surgery may be required if the infection has not cleared up even after the use of antibiotics and is also done in cases of bone erosion. This surgery will be done to drain the infected fluid from the ear and remove a part of this Mastoid bone. Complications like facial paralysis and vertigo need to be discussed with the surgeon before the surgery.

Getting a good night s sleep is essential for mental and physical wellbeing. Ideally, one should get at least 8 hours of continuous sleep every night. However, some people find this hard to achieve. They may have trouble going to sleep, wake up frequently or have a very poor quality sleep. 

Here are a few tips to help you improve your sleep: 

Set a sleep schedule: Like children, adults also need to go to sleep and wake up at the same time every day. This should be followed for at least 6 days a week. Having a sleep in the day may seem like a good idea but this can affect your ability to go to sleep in time at night and make you wake up the next morning feeling tired. Hence, train your body to sleep and wake up at the same time every day.
Avoid stimulants after sunset: Nicotine and caffeine can be very detrimental to your sleep cycle. The effects of these substances can often last for hours. Caffeine not only makes it difficult to fall asleep but can also make a person wake up frequently at night. Alcohol can make a person seem sleepy initially but can make him or her wake up earlier than usual and hence, disrupt the sleep schedule. So, avoid these substances for at least a few hours before going to bed. Instead, you could drink a cup of calming chamomile tea to soothe the nerves and help you sleep well.
Create the right sleep atmosphere: Ban the television, tablet and other mobile screens from your bedroom. The light from these devices makes it difficult to fall asleep and the material being seen can play on your mind for hours and make you toss and turn. Make your room as dark as possible to make it easier to fall asleep. Using blackout curtains can be a good idea. Also, make sure the noise and temperature levels are conducive to sleep.
Exercise: Exercise has many benefits. This includes better sleep quality. A workout tires the body and reduces the chances of waking up in the middle of the night. However, timing your exercise routine is very important. The ideal time for a workout is in the early morning or early evening. Do not work out just before going to bed as this can have a stimulating effect on the mind.
Limit naps: Avoid napping through the day. While this may seem like a good way to catch up on sleep, it can have a detrimental effect on the quality of your night sleep. If you must nap in the afternoon, keep it short. Training your body to associate sleep with darkness can make it easier for you to fall asleep at night.
Hence, if you are also having any sort of troubles with your sleep, immediately apply the above discussed tips in your daily life and you will see the results within a few days.

Tuberculosis refers to an infectious disease associated with the lungs, which is mostly caused by bacteria. There are two types of tuberculosis, that are pulmonary tuberculosis and extrapulmonary tuberculosis. There are various types under each type of tuberculosis. Here are some the possible treatments for both pulmonary and extrapulmonary tuberculosis.

What is pulmonary tuberculosis?
Pulmonary tuberculosis is a type of disease in which bacteria invade your lungs. It is possible that the bacteria in your lungs could kill you. However, fortunately if you have been taking the right medicines for your bacterial infection you can get cured immediately. The name of the bacteria which causes tuberculosis is known as the Mycobacterium tuberculosis. However, Mycobacterium tuberculosis can attack other parts of the body as well. When this happens, it is known as extrapulmonary tuberculosis.

What is extra-pulmonary tuberculosis?
Extrapulmonary tuberculosis is when tuberculosis affects in parts of the body other than the lungs. There are many parts of the body which tuberculosis can affect, including the lymph nodes, nervous system as well as the bone and joints. Luckily, it is easily curable.

Treatment for pulmonary tuberculosis
Firstly, it is worth noting that latent tuberculosis has no symptoms and there is no way you can pass it to another person either. However, it is still crucial that you take treatment for it. If you do not complete your treatment, then your tuberculosis will progress to a very dangerous form of tuberculosis. This is known as multidrug-resistant tuberculosis. Multidrug-resistant tuberculosis is sometimes abbreviated as MDR TB. There are plenty of medicines which people are recommended to cure tuberculosis. These include:
1. Isoniazid
2. Rifampin
3. Ethambutol
4. Pyrazinamide

Treatment for extrapulmonary tuberculosis
Extrapulmonary tuberculosis has pretty much the same symptoms as pulmonary tuberculosis. This is because extrapulmonary tuberculosis is the exact same disease which occurs to the patient, it is just that it affects a different body part. Therefore, the exact treatment recommended for pulmonary tuberculosis can be used to cure extrapulmonary tubercul

Types Of Tuberculosis: Pulmonary and Extra-Pulmonary and Treatment For Them

Glaucoma is a serious eye condition in which the optic nerve gets damaged and the situation gets worse over time. If untreated, individuals may go permanently blind. Most individuals, with glaucoma, have no previous symptoms or warning signs of this disorder and this is the reason why it is important to have regular eye check-ups.

Causes of glaucoma
Eyes have a liquid called aqueous humor. This fluid flows out of the eyes through mesh like channels for proper lubrication of the eye. However, there can be situations in which these channels may get blocked. In such a case, there would be a build-up of this liquid, thereby causing an increase in fluid pressure. This is usually a major cause of glaucoma. Although there has been no elaborate evidence of what exactly causes this blockage, doctors have noticed that this can be inherited.

Other less common causes include:

Any sort of blunt injury or chemical injury to the eye
Blocking of blood vessels inside the eye
Other inflammatory conditions
Improper eye surgery
Types of glaucoma
There are mainly two kinds of glaucoma than can occur:

Open-angle glaucoma: This is the most common kind of glaucoma and is also called wide-angled glaucoma. In this kind, the tubular meshwork through which the liquid flow occurs is normal. However, the fluid flow isn t the way it should be.
Angle-closure glaucoma: This is also known as acute glaucoma or chronic angle closure. In this case, the liquid is not able to drain properly because of the angle between the iris and the cornea being too narrow, thus causing the iris to be in the way. This can cause a sudden build-up of pressure, thereby leading to chronic glaucoma.
Facts about glaucoma

This disorder usually has no previous signs or symptoms and occurs all of a sudden.
This disorder mainly affects individuals above 40 years of age.
Glaucoma can be inherited.
People with diabetes have chances of suffering from glaucoma.
If not treated early, it may lead to permanent blindness.
Symptoms of glaucoma
Usually there aren t many symptoms to warn people about this disorder. However, one of the first signs is definitely losing peripheral or side vision. Other symptoms might include

Chronic vision loss
Visibility of halo around lights
Narrowed vision
Glaucoma is treated by any of the three methods:

Prescription eye drops in order to reduce eye fluid formation, thereby resulting in outflow increase
Laser surgery
Microsurgery
