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.

How to Prevent Your Child from Developing Type 2 Diabetes?

Type 2 diabetes (T2DM) is a chronic metabolic disorder that prevents the body from processing sugar or glucose. The disorder causes insufficient production of the hormone Insulin (responsible for regulating sugar into the different parts of your body); or the body's failure to respond to the hormone produced. Although no cure is available for T2DM, there are several ways in which you can help prevent Type 2 diabetes in your child. These are:

1. Get your child to indulge in some physical activity

Spending about 60 minutes of the day on physical activity can help your child to ward off Type 2 diabetes. In terms of screen time, it shouldn't be over 2 hours a day. By doing so, he or she ends up building his or her muscles as well as gets rid of extra fat from the body. An active life would also help your child to maintain an optimal body weight with obesity being a cause of this form of diabetes. Whether it's a sport like swimming, cricket or basketball, or even walking and dancing, physical activity in any form can help in preventing your child from developing Type 2 diabetes.

2. Plan a well-balanced diet for your child

Encouraging your child to have healthy foods and making right food choices can also lower his or her chances of getting this metabolic disorder. Foods high in fiber like whole grain cereals and bread, lentils, fruits, and vegetables should be consumed. Similarly, foods low in trans and saturated fats like lean meat, chicken, yogurt and cheese should be included in your child's diet. Processed foods, as well as sugary drinks, should be no-no when it comes to your child's diet.

3. Adopting proper eating habits

It is not only making the right food choices that are important but eating right as well is vital for preventing the onset of diabetes. Having meals with fix portion sizes is a habit that you need to develop in your child. Ideally, half the plate should be filled with vegetables and fruits; a quarter with lean protein like chicken; and the remaining with whole grain. To accompany the meal, make your child have one cup of no-fat or low-fat milk. Desserts like ice cream and cookies should be allowed only once or twice a week.

Post pregnancy, your first priority is to lose the extra weight you gain during pregnancy. Even though it is important to get healthy and toned again, it is equally important that you do not skip on nutrients. Your body is now using all its resources to produce breastmilk for your baby. What you eat doesn t always affect the breast milk s quality, but you do need to eat the right things to stay healthy.

Here are some diet tips you can follow - 

1. Stop counting calories: Generally, women who breastfeed need to eat 500 calories more than women who aren t. In other words, you need to consume 2000-2500 calories every day. However, you don t need to count calories throughout the day. Instead, you should eat when you are hungry. Also, the right number of calories depend on how your metabolism works, your weight and how regularly you breastfeed.

2. Lose the weight slowly and steadily: Honestly, pregnancy weight takes at least a year to get rid of. So don t rush, and give in to crash diets to lose weight. A sudden weight loss and calorie drop can affect your milk supply. Instead, focus on losing 1 pound every week.

3. Choose healthy foods: Complex carbs, vitamins and good fats are important for a healthy diet, since you need the nutrition and durable energy to sustain not only yourself, but also the newest addition to your family.

4. Eat fish-but carefully: Fish such as salmon is good for you, since it contains DHA (Omega 3 fatty acids) which has an important role in the development of your baby s brain and eyes. Limit your consumption however, since maximum fish contain mercury, which in high amounts, can harm your child.

5. Take your vitamins: Don t stop taking your prenatal multivitamin and mineral supplements. Calcium, vitamin D and DHA supplements can enrich your diet and help you nurse your baby better.

Epilepsy is a neurological condition that leads to recurrent seizures. Seizures arise when electrical activity in the brain suddenly surges causing a temporary disturbance within the messaging systems located between the brain cells.

Epilepsy is more common in children below the age of two years and adults above the age of 65 years.

Seizure Types

Seizures are classified into two main categories depending on their area of impact. 

A focal seizure is one that affects only one part or area of the brain whereas a generalised seizure affects the whole brain. Further, both focal and generalised seizures have various sub-categories which are as follows-

Previous nomenclature- 

Partial Seizure

  Simple Partial Seizure
  Complex Partial Seizure
  Partial Seizure with Secondary Generalization

Generalized Seizure

  Absence Seizures
  Myoclonic Seizure
  Atonic Seizure
  Tonic Seizure
  Tonic-clonic Seizure
  Mixed Seizure
  Status Epilepticus

Latest nomenclature of seizure types:

Focal seizures-

  Focal aware seizures
  Focal impaired awareness seizures (previously called complex partial seizures)
. Bilateral tonic clonic seizures

Generalised onset seizures-

  Tonic clonic seizures.
  Atonic seizures (sometimes called drop attacks) and tonic seizure.
  Myoclonic seizures.
  Absence seizures.

Symptoms

The well know symptom of epilepsy is a convulsion/ fit, a few other symptoms include-

  Intermittent spells of fainting. When this happens the patient is likely to lose control of his/her bladder or bowel movements. Following this, the person is likely to suffer from extreme tiredness.
  Spells of a blackout with difficulty in remembering
  Becoming unresponsive to any instructions or questions asked during brief periods of time
  Bouts of continuous blinking without any known reason
  Inappropriate movements that keep on occurring
  Changes in sensory perceptions
  Sudden stiffness in the body

Reasons for Epilepsy

Messaging systems within the brain are responsible for every function that goes about in your body. A disruption to this system caused by defective electrical activity leads to epilepsy in a person. Many people inherit epilepsy while others may develop this condition as a result of-

  Head trauma sustained during an accident
  A stroke or a tumour that has affected the brain impairing its normal capabilities
  An injury to the brain before or during birth
  Associated with developmental issues
  Infections of the brain

Treatment for Epilepsy

Epilepsy in childhood can be treated by using medications and by adopting dietary changes in some cases. Medications for epilepsy mainly include-

  Anticonvulsants - Helps control seizures and manages the symptoms of epilepsy
  Medications for nerve pain - Reduce pain that is caused by the damaged nerves

These medications should be consumed as and when prescribed by the doctor. You must consult a paediatrician for this, as he/she will take your child s physical and mental in consideration before starting the treatment.

Seizures that occur in childhood may be benign. This means that it will not continue into one s adult life. Further, those children who have suffered from epilepsy in their childhood have been seen to have normal mental and intellectual development in their adulthood. However, some epilepsy syndromes in children can have a devastating effect on the child.

Seizure threshold is a term that is used to refer to the conditions that are important for the production of seizures. The threshold is lower for people who are more prone to having seizures whereas the threshold is higher for those who do not have a tendency to suffer from seizures.

Spitting up, refusing to try new foods and occasionally turning up their noses at feeding times, is normal but consistently refusing food and water, vomiting and allergies may indicate an underlying medical condition that requires attention. Common feeding problems that affect infants include sucking, prolonged chewing without swallowing, holding food in their mouth and grabbing food. Infants who are unable to close their mouths in order to keep food inside may also be said to be suffering from feeding problems.

Feeding problems could be triggered by medical conditions like a cleft palate, premature birth, respiratory problems, low birth weight etc. or by non-medical reasons such as the child s feeling of being unloved or stressed. Symptoms of feeding problems vary from infant to infant. However, some of the common symptoms exhibited are:

Problems with chewing

Excessive drooling

Refusing to eat foods or drink liquids

Long feeding times

Coughing or gagging while feeding

Difficulty with breast or bottle feeding

Nasal stuffiness while eating

Poor weight gain

Recurring respiratory infections

Vomiting or excessive spitting up of food

Arching the back while feeding

Disinterest in feeding

Though feeding problems are minor in most cases, it is important to consult a doctor if this behaviour continues over a period of time. This is because the child may be suffering from an underlying medical condition or could be at an increased risk of suffering from dehydration, aspiration and lung problems. It could also lead to delayed physical and mental development, speech problems and cognitive issues.

Feeding problems are addressed in many different ways. The first step to dealing with feeding problems is to change the texture and temperature of food being given to the baby. In addition, try changing the posture of the baby while feeding.

In some cases, mouth exercises may be needed to strengthen the mouth muscles. Chewing exercises and tongue movement may also help reduce feeding problems.

Encourage your infant to try different types of food by including different textures in their daily meals. Alternating food textures and liquids can make it easier for the infant to swallow the food. Do not force your child to eat in a hurry but let him or her take their own time.

In cases where the infant is not gaining weight, the doctor may suggest nutritional changes and a specific diet to help gain weight. In emergency cases, hospitalisation may also be required and your baby may be given a feeding tube to ensure he or she receives adequate nutrition.

12 Signs Your Child Is Not Eating Properly!

Growth is the most important aspect of childhood, one that distinguishes children from adults. Growth is affected by a number of diseases and growth failure is often the first sign of a serious disease. Unfortunately children with growth failure present very late when no help is possible. 

Why to worry?

Growth is the best marker of health and growth failure may be caused by a seious disease. Moreover children with short stature have lower self esteem. 

When to worry? 

Plot the height of your child in the growth chart and if it is below the lower limit visit a doctor. Alternatively if your child's height is less than the formula (Height = Age in years x 6 + 77 cm) it may be a cause of concern. Growth stops at the age of 14 years in girls and 16 years in boys. Hence the child should be reviewed latest by 10 years for girls and 12 years for boys. 

What causes growth failure? 

Growth failure can be due to a number of causes including poor nutrition, lack of physical activities and low genetic potential with parents being short. Short stature can also be caused by a number of diseases like thyroid problems, growth hormone deifiency and celiac disease (wheat allergy). 

How can I improve my child's growth?

Please encourage your child to play for atleast 1 hour a day. It is important to restrict screen time including television, computer, tablets and mobiles to less than an hour. Increased protein and calcium intake with more milk, pulses and vegetables also helps in improving growth. Growth hormone is produced during sleep. Sleeping for at least eight hours a day is therefore essential for a child to achieve good growth. 

What can be done if my child is very short? 

Please consut a doctor to identify the cause of short stature. Most conditions are readily treatable. Children with growth hormone deficiency respond dramatically to growth hormone. Growth hormone is also being used now in children with turner syndrome, familial short staure, small size at birth and kidney disease. 

Time is important- act now if your child is short.
