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.

9 Home Remedies for Sinus 

Nose incorporates an intricate system of narrow passages and hollow, air containing spaces connecting to eyes and ears that enable us to inhale the air before it reaches our lungs. And the problem of sinus is directly linked with the nose. Basically, Sinus is a cavity within bones of face connected with nasal cavities and the main cause of sinus is allergies. But internally our nose has to suffer a lot when this problem occurs. But there are few tips that can be of great help during sinus. Let’s see them one-by-one

1. Drink plenty of water: While you are suffering from sinus, you must keep drinking water at short intervals because this won’t let the sinus get dry which is very essential for the treatment of sinus. Prefer taking lukewarm water.

2. Oregano oil: Adding few drops of oregano oil in water and having it 2-3 times a day for a week will provide relief when suffering from sinus and it will also make recovery faster.

3. Eat vitamin C: Eat citrus fruits which are rich in Vitamin C. Although some people avoid it thinking that it will aggravate the sinus problem but taking Vitamin C is helpful in sinus problem.

4. Fruit juice intake: Taking fruits juices also helps in thinning out mucus and preventing sinuses from blocking.

5. Warm compressor on face: Keeping warm compressor on your face will give relief from discomfort and will open blocked nasal passages.

6. Keep your head propped up while sleeping: Sleeping on a couple of pillows will be a good idea as it will help in proper breathing.

7. Spicy food intake: Taking too many spices is never a good idea but taking it in limits can actually solve many problems and one of them is clearance of sinus. Spices like mustard, hot pepper, curry and horseradish etc. helps in clearing sinus. It opens your nasal passages.

8. Hygiene: Hygiene is the first and foremost thing to be kept in mind when this problem occurs.

9. Humidifier: Keeping humidifiers in your room also helps in providing relief during sinus.

Cancer like most other diseases has the best rates of recovery with early detection and intervention. As there are no regular health screenings for blood cancer, only the awareness about the early warning signs can save your life. November is designated as the Lung Cancer Awareness Month, to ensure every individual is equipped to fight against lung cancer right from the start. Here are 4 vital facts you must know to win your fight against blood cancer.
Lung cancer is also known as pulmonary carcinoma or cancer of the lung. It occurs when DNA mutations develop in the cells/ tissues of the lungs leading up to uncontrolled growth in the tissues of the lung. By far, it is known to be the most common cancer in Asia.

1. Type: lung cancers can present as one of the following types: 

Non-Small Cell Lung Cancer (NSCLC): Most common type of lung cancer and constitutes nearly 85% of all lung cancers. The sub-types of NSCLC are as follows:
Large cell carcinoma
Squamous cell carcinoma (SqCC) (Epidermoid)
Adenocarcinoma   accounts for majority of the NSCLC.
Small Cell Lung Cancer (SCLC): It is also known as oat meal cancer and tends to spread (metastasize) quickly. This constitutes about 15% of the lung cancers.
Mesothelioma: It is a rare cancer that develops in the mesothelial cells of the pleural or peritoneal surfaces. It usually arises in the pleural membrane lining the lungs, known as pleural mesothelioma. One that arises from the peritoneum is called the peritoneal mesothelioma and the one that arises from the pericardium is known as pericardial mesothelioma. Lastly, it can also arise from the tunica vaginalis known as testicular mesothelioma. People working with or prior exposure to asbestos are mostly at risk of developing mesothelioma. The latency period between time of exposure and development of mesothelioma can be somewhere between 20 to 40 years. Maximum of the patients who develop mesothelioma are men.
2. Gender: It affects the male populace predominantly. It is more common in men than in women and in those of lower economic status. However, the incidence of lung cancer, in women too, is on the rise of late.

3. Etiology: Cigarette/ Tobacco smoking remains the most important cause of lung cancer accounting for 85   90% of the cases. Incidence/ risk is proportionate to the number of cigarettes smoked irrespective of the age. Also, environmental toxins including smoke from burning black tar, exhaust gases from automobiles etc. too contribute actively to various lung diseases including cancer. People working in asbestos manufacturing factories who are exposed to asbestos dust are also likely to get lung cancer. Tuberculosis too is an additive risk factor. Again, people who have received ionizing radiation especially to treat Hodgkin Lymphoma or other malignancies also run the risk of developing lung cancer. Above-mentioned causes apart, genetic factors may also play a role.

4. Features: Lung cancer clinically presents in the following ways mainly. Signs & symptoms of malignant mesothelioma are as enumerated below

Difficult/ labored breathing (Dyspnea)
Chest pain
Palpable chest wall mass
Discordant chest wall expansion
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Night sweats
Signs & symptoms of non-small cell lung cancer (NSCLC) are as enumerated below. Majority of patients are symptomatic at diagnosis

Chronic cough
Difficult/ labored breathing (Dyspnea)
Chest pain
Blood stained sputum (Hemoptysis)
Hoarseness
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Weakness
Bone pain
Pleural or pericardial effusion
Superior vena cava syndrome
Brachial plexopathy
Neurologic pain
Hypercalcemia of malignancy
Signs & symptoms of small cell lung cancer (SCLC) are as enumerated below

Symptoms as per the points 8   18 depicted above for NSCLC are applicable for SCLC as well. Additionally, patients suffering from SCLC may have:

Fever associated with chest infections like bronchitis/ pneumonia that refuse to go away or keep coming back
Horner syndrome
Paraneoplastic syndromes including encephalitis/ sub-acute sensory neuropathy, hyponatremia, acromegaly, cancer associated retinopathy, ectopic corticotropic syndrome etc all.
5. Screening: is generally recommended for asymptomatic/ symptomatic populations as surveillance for high-risk individuals   who are either current or former smokers (quit smoking within the last 15 years) have at least a 30 pack-year smoking history and those who do not have any prior history of lung cancer. The goal of screening, as usual, is to be able to detect & diagnose lung cancer at an early stage which is potentially curable. It is mostly radiologic with a low dose helical computed tomography (CT) scan being more effective in detecting early-stage lung cancer than a chest radiograph can.

6. Diagnosis: Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for an accurate diagnosis. Following are the diagnostics employed mainly:

Blood: Hb may be low, TLC, ESR and polymorphs increased. Adenocarcinomas are likely to express thyroid transcription factor 1 (TTF-1) or carcinoembryonic antigen (CEA). On the other hand, mesotheliomas are likely to express Wilms Tumor -1 (WT-1) protein and Calretinin.
Imaging: Thoracoscopy, Bronchoscopy, X-Ray, CT Scan etc all. Positron Emission Tomography (PET) / CT scan and Magnetic Resonance Imaging (MRI) scan help detect metastasis if any.
Biopsy: It clinches the histologic diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, chemotherapy and radiotherapy as contextually appropriate. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as would be feasible contextually.

8. Prognosis: Preventive measures, earlier diagnosis and right early treatment are key for effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for early-stage lung cancer are more. The cure/ recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all. The primary determinant of prognosis in NSCLC is the stage at which the cancer is diagnosed. For non-metastatic cancers, however, it is the nodal status that determines the stage and hence the prognosis.

9. Prevention: Rightly said, prevention is always a better choice. Cigarette smoking is to be avoided by all means as it is the single major cause of lung cancer. Even exposure to cigarette smoke (passive or secondhand) is also an established cause of lung cancer and is known to increase the risk of lung cancer in non-smokers as well. Preventing exposure to secondhand smoke can be helpful in decreasing the incidence and mortality of primary lung cancers. Above-mentioned apart, other important risk factors such as exposure to ionizing radiation, environmental carcinogens like smoke from burning black tar, exhaust gases from automobiles, outdoor air pollution, and occupational exposure to asbestos, arsenic, beryllium, nickel, cadmium, chromium etc all too are known to increase the risk for lung cancer and mortality thereof. In fact, cigarette smoking is known to potentiate the effect and hence the lung cancer risk of many of the above-mentioned carcinogens, multi-fold, in smokers. Thus, either eliminating or reducing the exposure to the above-mentioned carcinogens can lead to a decrease in the risk of lung cancer and incidences thereof. Furthermore, randomized clinical trials indicate that high-intensity smokers (only) who take supplementation of beta-carotene have an increased risk/ incidence of lung cancer. Vitamin E supplementation, on the other hand, does not affect the risk of lung cancer as indicated by the trials.

Lung Cancer Awareness Month - Lung Cancer In Nutshell!

Sinuses are cavities in our skull behind the nose which spread out in a pattern. These cavities are lined with tissues and mucosal membranes and are essential for our breathing process. Sinusitis is a condition where the tissues within the cavities become inflamed which results in the sinus cavities being blocked due to a buildup of fluid.

What are the conditions that can lead to sinusitis?
Some of the conditions that can cause nasal polyps are explained as follows:

Nasal polyps are small growths of tissue within the lining of the nose which may block the sinuses, resulting in sinusitis.
Common cold is also a culprit which may result in sinusitis
If your septum or the bridge between the holes of the nose is deviated (this condition is referred to as a deviated septum), you may be prone to developing sinusitis.
The lining of the nose may swell in a condition known as allergic rhinitis and cause sinusitis as well.
Types of sinusitis
There are multiple types of sinusitis which may affect people and also on how long they last. The various types of sinusitis are explained below:

Acute sinusitis: This is the most common form of sinusitis that lasts usually between 2 to 4 weeks. It starts with a cold, blocked nose and turns into facial pain that usually starts very suddenly.
Chronic sinusitis: This is a form of sinus infection which can have a debilitating effect on your life and may last for 12 weeks or longer.
Sub-acute sinusitis: This is somewhere between acute and chronic sinusitis and may last from anywhere between 4 to 12 weeks.
Recurrent sinusitis: This form of sinus infections tend to be a variation of acute or sub-acute sinusitis which tends to occur multiple times a year.
Symptoms of sinusitis
The manifestation of the symptoms of sinusitis may be different from person to person and also on the type of sinusitis you are suffering from. However, there are some generic symptoms that are common to all forms which are mentioned as follows:

Smelling senses may be dulled
Facial pain
Congestion accompanied by a cough
Nose may be blocked, stuffy and may also be runny
Other symptoms may also include bad breath, fatigue, or even dental pain
Nasal cavity may have pus and it may drain from time to time
It is best to consult a doctor quickly, if you have been having any of these symptoms. The doctor can prescribe nasal decongestants and antibiotics which can help. If you have chronic or recurrent sinusitis, then more aggressive and advanced treatments may be required.

Sinusitis - Conditions That Lead to It!

Doctors believe that tonsils and adenoids have a hand in helping the body fight infections. A common problem children face is enlargement of these organs.

Even though most cases of adenoid and tonsil enlargement subside naturally after a few days, in some instances of the disorder, severe symptoms may force you to seek treatment for your child. Here is a look at some complications from an enlarged adenoid and tonsils.

Complications:

  Hearing loss and chronic infection in the ear is a common complication. This occurs when the enlarged lymph tissue blocks fluid transfer in the ear.
  Sinus infections that recur over time
  Sleep apnoea is a common side effect of adenoid and tonsil disorders. This leads to difficulty in breathing while your child sleeps.
  Weight loss is an indirect consequence of enlargement in these lymph tissues. Your child may not be able to eat properly due to the pain experience while swallowing

In case of severe complications, doctors will recommend getting the adenoid and tonsils removed from your child s body. Coblation is the best option in such a case.

What is coblation surgery?

Coblation stands for controlled ablation. It is a minimally invasive surgical procedure where an electrical handpiece is used to  burn  the affected tissue in the throat of children. Extremely low temperatures rectify the problem by  burning  the affected tissue. When the coblation method is used to remove both the tonsil and the adenoid lymph tissues, the procedure is known as Coblation Adenotonsillectomy.

The coblation method has replaced the older method where metallic surgery instruments were used for the removal of these tissues. Such crude methods often resulted in post-operative complications, especially in children.

Here are some benefits of Coblation Adenotonsillectomy:

  Less bleeding during the surgical procedure, limiting dangers to the child s health
  Less pain and discomfort post the surgery for the child, which leads to faster recovery
  Decreased risk of haemorrhage post-surgery

Consult an ENT specialist to know more about Coblation Adenotonsillectomy. They will be able to clarify any doubts you have regarding your child s safety during the procedure as well.

Adenoid & Tonsil Problems In Chlidren!

You are out in public, and a person next to you is incessantly coughing. It is natural to be worried if it is bronchitis and the possibility of you getting infected. Read on to know about the condition and if it is really contagious. Bronchial tubes are the airways in the lungs, and when they are inflamed due to an infection or an underlying medical condition, it results in bronchitis. Bronchitis can be acute or chronic and depending on the cause, may or may not be contagious.

Types of bronchitis
Chronic bronchitis occurs when the airways in the lungs get irritated again and again. Though it s a severe health condition that requires medical attention, it is not as contagious as it occurs due to the exposure to certain chemicals, dust, cigarette smoke or smoke from a fire, air pollutants that irritate the lungs.

On the other hand, acute bronchitis that usually lasts for one to three weeks is considered to be contagious because this particular type of bronchitis happens due to the flu or cold viruses. It is the infectious properties of the viruses causing it that makes it contagious.

Transmission
In the case of acute bronchitis, since it is caused mainly due to viral infections when an infected person coughs, sneezes or talks, the viruses get transmitted to others in the surrounding. Hence it can spread quickly.

Symptoms
Some of the common symptoms of acute bronchitis are a hacking cough, production of excessive mucus, shortness of breath, and feelings of discomfort in the chest. Note that as long as the infection is present, acute bronchitis remains contagious. Once the infection is gone, it is no longer contagious, though, the symptoms, like a persisting cough, may stay for several weeks afterward.

Prevention
Maintaining a healthy hygiene, such as washing hands regularly or keeping the surfaces clean, or using a handkerchief when coughing or sneezing can help in preventing the spread of the infection as well as getting affected with it. Also, taking flu vaccinations and quitting to smoke can also assist in preventing lung infections.

Treatment
For the majority cases of acute bronchitis, the condition is resolved by itself within a few weeks and antibiotics may not be an ideal treatment option if the acute bronchitis is caused by a virus. The most recommended treatment options that can quicken the recovery process are taking rest, opting for prescribed over-the-counter medications, drinking lots of fluids, inhaling the steam of hot water, whether from the shower or a bowl of hot water.

People who have asthma or chronic bronchitis sometimes may develop acute bronchitis as a result of further complications of their present lung conditions and not as a result of virus invasion. Therefore, the chances of such acute bronchitis being contagious are less than those caused by influenza viruses or bacteria.

Thus, acute bronchitis due to a viral infection is more contagious than chronic bronchitis that is due to an underlying medical condition like asthma and other lung diseases. With a few simple and effective measures, such contagious infections can be prevented.
