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?

Hypertension or high blood pressure is common in pregnant women, even in those who have no previous history of high blood pressure. This leads to complications in about 6 to 10% of all pregnancies around the world. High blood pressure may develop before or after conception and as such needs special medical attention.

Hypertension prevents sufficient flow of blood to the placenta and this inhibits the normal growth of the fetus. This could result in low birth weight of the child. However, if diagnosed in time and treated properly, hypertension does not affect the child's health too much. There are various types of hypertension during pregnancies, such as:

Gestational hypertension: This type of hypertension is developed about 20 weeks after conception. There is no abnormality in urine or any signs of other organ damage (as is common with hypertension during pregnancy) but the condition can worsen and complicate very quickly. Pregnant women below the age of 20 and above the age of 40 are often diagnosed with high levels of blood pressure. Women who have heart or kidney conditions before pregnancy and women carrying more than one child are also likely to develop gestational hypertension.
Chronic hypertension: Chronic hypertension is high blood pressure which develops around 20 weeks before conception and does not normalize within 12 weeks after childbirth. The patient may also have been suffering from high blood pressure for a long time but the complications appear only during pregnancy because high blood pressure rarely exhibits symptoms without an associated condition.
Chronic hypertension superimposed with Preeclampsia: Women who have hypertension before pregnancy may develop even higher blood pressure levels during pregnancy. This leads to several health disorders like frequent headaches, fatigue and depression.
Preeclampsia: Preeclampsia is often a serious complication of gestational pregnancy and affects about 5% to 7% of all pregnancies globally. Gestational pregnancy does not always develop into preeclampsia but it needs to be diagnosed and treated in time to avoid the complication. Women who have conceived for the first time or have a history of hypertension in the family are at a greater risk of preeclampsia. The symptoms of the condition are throbbing headaches, blurred vision, nausea and vomiting, pain in the upper abdominal region and shortness of breath.

Types Of Hypertensions Experienced During Pregnancy

Screening for cancer of the colon or large intestine and rectum is a proven way of saving a person from the impacts of colorectal diseases. This is partly because colon cancer is something that can be prevented if detected at an early stage and the polyps which may advance to cancer are removed properly. Thus if you are turning 50 soon, be prepared to present yourself for a screening colonoscopy that will help you ensure good health and well-being. It may sound uncanny, but do you know that 50,000 people across the world die from colorectal cancer every year, and it is ranked second in terms of cancer-centric deaths.

Understanding the importance of having colonoscopy
You may wonder how a painful, invasive, embarrassing, uncomfortable and time-consuming health test may be called a present. There are reasons enough. A screening colonoscopy is able to expose a cancerous tumour that's presently under way and cast light on the chances and risk factors that may precede it. When you choose to intervene early, you have the power to nip those risks at their budding stage, much before those malicious cells become malignant.

Spreading of the colorectal cancer
Your large intestine is really a big and last organ of the gastrointestinal system where the small intestine discontinues. Its primary function is to remove the water out of the leftover solids of digestion and get rid of them in the form of stool. Cancer may start to develop anywhere within the tube that expands 5 feet long and squares the vacant area of the abdomen. The large intestine expands up towards the right side, i.e. the ascending colon and then turns left through the liver, i.e., the transverse colon, bending down right at the spleen on its left, i.e. descending colon and loops to the middle, i.e., the sigmoid colon before it runs across the rectum and ends at the anus.

People who need a colonoscopy
To simplify matters, it can be said that all adults are at a potential risk of the colorectal cancer, including those people who lead a healthy life. But some people are at a higher risk. Those individuals have a specific gene mutation that predisposes them to develop into numerous polyps. The risk is also high with people who are first-degree relatives of a person diagnosed with cancer before the age of 50. People with Ulcerative colitis, various types of inflammatory bowel diseases and Crohn's disease are also at a higher risk.

Colorectal cancer is a serious ailment and screening colonoscopy is a feasible means of detecting any polyps that may be cancerous in the future. Speak with a reputed gastroenterologist today to stay ahead of the disease.

When Should You Start Having Colonoscopies?

Growth hormone or somatropin is responsible for cell growth as well as reproduction. But insufficient somatropin production by the pituitary gland may result in lack in height. It is mostly caused by a serious brain injury, any prevalent medical condition or might occur as a birth defect.

Types
1. Congenital ghd - this form of ghd appears from at the time of birth itself.
2. Acquired ghd- ghd can be acquired during later life as a result of trauma, infection, tumor growth within the brain or radiation therapy.
3. Idiopathic ghd- idiopathic ghd is the third, and comparatively worst kind of ghd since it has no treatment.

Ghd is mostly permanent, but can also be transient. Read on to know how to detect whether you or your child is suffering from growth hormone deficiency (ghd).

Symptoms
Childhood onset
1. Restricted height- compared to other children of your child's age, he/she may be of shorter height, which is a rather conclusive sign to detect somatropin deficiency.
2. Chubby and comparatively younger appearance- your child may have a proportionate body, but if he/she is unnaturally chubby and has a baby-face compared to other children, he/she may be suffering from ghd.
3. Late puberty- your child's puberty maybe later than usual or even not appear at all, depending upon the gravity of the ghd.
4. Hypoglycemia and exaggerated jaundice- low blood sugar is amongst the most primary manifestations of ghd, along with extended duration of jaundice.
5. Micro-penis- micro penis condition is one of the incident signs of ghd, which later escalates to growth deficit as the infant gets older.

Adult onset
1. Fatigue- adults with ghd may experience extreme tiredness throughout the day, with reduced muscle strength.
2. Osteoporosis- osteoporosis, along with bodily deformities, is a common sign in adults with ghd.
3. Lipid abnormalities- a test of your lipid profile may reveal abnormalities in ldl cholesterol, insulin resistance, and impaired cardiac functions.

Tests to determine ghd
1. Physical test- a chart is drawn to determine the proportion of height and weight with respect to your age to detect anomalies.
2. Hand x-ray- a hand x-ray can determine whether the age of bones are at par with your age.
3. Mri-mri scan can determine the health of your brain and pituitary gland.
4. Test for other hormones- growth hormone may not be solely responsible for your health condition, so it is important to determine if other hormone levels are all normal.

Treatment
1. Hormone supplements- hormone supplements like corticosteroids (hydrocortisone or prednisone), levothyroxine (levoxyl, synthroid, etc), and others work to replenish the deficiency of pituitary hormones.
2. Growth hormone injection- gh is injected beneath your skin, to cure gdh. This is a long-term treatment and requires constant monitoring.

All About Growth Hormone Deficiency

It is nightmarish when your babies have cough, congestion and stomach aches – and they happen often. The littles ones can't express very well, but as parents you might be able to figure out. Here are common and highly effective home remedies to these baby ailments.
 
1) COLD & COUGH : Honey is highly soothing for temporary cough relief. You can prepare a warm drink with ginger, honey, and lemon juice to drink before bedtime. The ginger and lemon soothe the throat, and the honey loosens up mucus and also acts as a gentle cough suppressant.  Don't give honey to babies ages one or under, though, due to the risk of infantile botulism. For the really little ones, a hot steam vaporizer usually does the trick. 
 
2) NASAL CONGESTION: A stuffy nose is an added challenge with babies and toddlers, as they can’t blow their nose. Prepare a solution of salt in lukewarm water, put this saline solution into the nose, then let your baby lie down for a while, and use the aspirator to remove the loosened mucus. This remedy is safe for babies as well as toddlers.
 
3) STOMACH UPSET/VOMITING:  Stomach aches or infections are the most difficult to get around and can be highly uneasy for the child. Try giving light liquids like dal/rice and vegetable stock, the best that works for everything is breat milk. If you can't breast feed, try to boil fennel seeds (sauf) in milk to make the baby's stomach feel better.

3 Must-know Home Remedies For Every Parent

Children are much more susceptible to tooth decay and gum disorders than grown-ups. This is because the gum and teeth in toddlers are very delicate. Moreover, children are more attracted to sweets and other food items, which cause damage to the teeth.
Here are several ways to protect the teeth of your little one:
1. Have a dental checkup: you should take your child to a dentist on his first birthday. Early prevention is important as any kind of problem in the teeth will be detected and this will save you from a lot of trouble in the future.
2. Teaching healthy habits: brushing is very important and you should teach your child to brush regularly, more than once a day. Before the development of teeth in your baby, you should brush his gums gently by using water on a soft baby toothbrush or with a clean and soft cloth. After developing teeth, brushing must be practiced with delicate toothbrushes and fluoridated toothpaste. If several teeth touch against each other, you should use flossing. Brushing is essential before going to bed, and no food should be taken after brushing.
3. Prevent" baby bottle decay: you should not let your child go to sleep with a bottle of juice or milk. The sugar contained in these liquids sticks to the child's teeth, which activates bacteria and may lead to tooth decay.
4. Avoid giving juice to your child: juice may be healthy for the body, but it leads to tooth decay in little kids. The amount of regular juice intake should never be above four ounces.
5. Avoid excess use of a sippy cup: sippy cups enable children to shift from bottles to a glass. However, all day long usage of sippy cups should be restricted as it may cause decay on the front and back portions of teeth, when the drinks are rich in sugar.
6. Be careful about sweet medicines: many medicines meant for children are sugary and stick to the teeth, increasing the chance of cavities. Several antibiotics cause overgrowth of candida or yeast and cause an oral disease known as oral thrush. This disease causes creamy patches on the tongue. In case your child needs sweet medicines, brushing should be increased.
7. Stop using a pacifier by the age of 2 or 3: pacifiers are good for children, but using pacifiers for a long period of time affects the lining of teeth. The shape of the mouth may also change. Hence, do not let your child use pacifiers after 2 or 3 years of age.
Children are quite prone to teeth disorders and decay in the teeth. Hence, measures must be taken to protect the teeth of children from any kind of disorder.
