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?

This is a very common condition seen in toddlers. When the legs are brought together then there is a gap at the level of the knee. It happens because of inward bowing of thigh bone or tibia. The deformity may appear to increase on standing.

Daily requirement of calcium

The optimal primary nutritional source during the first year of life is human milk. Premature infants have higher calcium requirements than full-term infants while in the nursery. These may be met by using human milk fortified with additional minerals or with specially designed formulas for premature infants. Around 6 months of age when weaning foods are started, food items rich in calcium should be added. Readymade formulas are fortified with calcium but one must remember that the bioavailability of calcium from human milk is greater than that from infant formulas or cow's milk. Hence breastfeeding should be encouraged. In children age 2-8 years the daily requirement is around 800 mg/d. In children 9- to 18-year-olds the daily requirement is 1,200-1,500 mg/day.

Some of the common items that are rich in calcium are.

Food Item	Quantity	Amount of Calcium in each serving
Milk	1 cup (240 ml)	300 mg
Cheddar cheese
1.5 oz (42 g)	300 mg
Spinach cooked	1/2 cup (90 g)	120 mg
Sardines or salmon with bones	20 Sardines (240 g)	50 mg
Sweet potatoes	1/2 cup (160 g)	44 mg
Vitamin D:

Babies younger than 1-year-old need 400 IU of vitamin D a day. Kids older than 1 year need 600 IU or more of vitamin D a day. Our bodies make vitamin D when our skin is exposed to the sun. The recommended exposure to sunlight is at least 30 min every day. There are various fortified food items that have vitamin D. Also medicines are available which can provide the daily requirement of Vitamin D

Physiological genu varus. In most of the toddlers, the legs are curved inwards. They should improve over a period of time. The legs should straighten by 2 yrs. The child should be investigated if the deformity is severe; the deformity is only in one leg, if the child complains of pain and if the child appears unusually short.

3 Common skin problems in teenagers

Problems with the skin during the teenage years are very common. Although skin issues can be really stressful, the right skin care treatment can help in controlling the problems you may face during this time. Here are some of the skin issues that you may face at this stage of life and ways to prevent them:

Oily Skin: Oily skin is a very common occurrence during teenage years. To a certain extent, oily skin may be due to genetics but for some, it may be due to hormonal changes that cause excess oil to be produced on the skin surface. In order to not inflame the skin further, individuals with oily skin shouldn't overly scrub their skin as well as not use harsh cleansers to clean the face. More importantly, when you do use a cleanser on your face, you should only do so two times a day. If you go overboard, it would only do more harm than good.

Acne: Whether it is blackheads, whiteheads or spots filled with pus, acne affects about 80% of teenagers at some point in their lives. Teenagers are more prone to this problem because the hormone levels during this time are especially high, resulting in an increase in the magnitude of sebaceous glands and the oil that is produced. When too much oil is produced, this, along with dead skin cells block, the follicles, giving rise to acne. There are certain ways in which you can prevent it from occurring, such as always having a bath after any strenuous activity, not picking or touching the problem areas and washing acne-prone spots only two times a day.

Excessive Sweating: Excessive sweating is another major cause of concern for teenagers. The problem can be due to two different conditions - stress or hyperhidrosis (a condition wherein you sweat excessively on a daily basis). Wearing clothes made from cotton, using antiperspirants as well as avoiding drinks and foods that may cause episodes of excessive sweating are some of the ways in which you can keep the problem in control.

Early treatment can help better your child s cognitive skills that can help him/her cope better with the surroundings and circumstances. The treatment options include behavioral training whereby self-help or social skills training is used to work on the child s communication skills and behavior. Specialized therapy is another option whereby the therapies are directed at a particular aspect of the child, primarily speech or physical functioning. 
Focus on your child s diet: Diet plays an important role in the regularization of any disease. Even in case of autism, deficiency of certain vitamins or minerals makes it very important to analyze the diet and then assess it. Consult with the doctor before making any modification to the child s diet. 
Behavioral training: Behavioral training is an aspect of autism treatment that allows the child to adapt to various conditions. Before a child undergoes behavioral training, it is advised to assess his/her behavior, functional abilities and the environment your child belongs to. The objective of this therapy or training is to induce desired behavior and get rid of the undesirable ones.

Tips for Parents to Deal with Autistic Children 

Fluoride products for the teeth have immense importance in dentistry. Fluoride is one such chemical, the balance of which is highly required for strong and healthy teeth. However, there is an optimum amount of fluoride needed for teeth. Anything lesser than that or greater than that can cause harm and serious teeth and gum problems and tooth decay. The best option, therefore, is to get a fluoride based toothpaste or mouthwash, which will keep on providing the teeth with the optimum quantity of its daily dose of fluoride.

The benefits of fluoride products
Before delving into the types of fluoride products available, let's have a look at the benefits of fluoride on teeth. Fluorides actually save the teeth from dental caries. It happens such that fluoride makes a certain mineral bonding on the teeth which is called fluorapatite. This is not normally found in human teeth, but when teeth damage is done, then to heal it fast this compound is needed to repair the damages. This adds to the mineral bonding in the teeth and strengthens the teeth.  

The fluoride products
The various fluoride based products, which you may use are as follows:

1. Fluoridated water: Fluoridating water is a simple process where the optimum amount of fluoride is mixed with drinking water so that drinking the water automatically keeps on adding fluoride to the body and keeps in contact with teeth. This therapy alone is enough and needs no more therapies generally. But not all water reserves contain this, and it's not possible to add fluorides to all water reserves. That is why the other fluoride treatments are needed.

2. Fluoride toothpaste: This is one of the most common forms for fluoride treatments. Every common daily use toothpaste contains a 0.22 to 0.312 percent of fluoride, and this is highly beneficial to the teeth for healing of decay and fast repairs. It lets the teeth get stronger. 

3. Mouth Rinses: Fluoride mouth rinses are an option. The sodium fluorides commonly used in the rinses are used in small amounts in the product which is used just like toothpaste and washed off.

4. Fluoride foams and gels: The foam and gel are used when the teeth of the child or adult are under high risk of cavities. The foam or gel is rubbed on the teeth, and kept for a while and then washed off. The typical application time is 30 minutes. 

5. Varnishes: The fluoride varnishes are just like gels, and they are also used on the tooth surface similarly. It's the choice of the dentist or patient as to which one they want to go with. Besides, these slow fluoride releasing devices, medical supplements and lozenges are also there, which slowly release the optimum amount of fluorides to keep the teeth strong and healing.

Use of Fluoride Products for Teeth

ADHD i.e. Attention deficit hyperactivity disorder is a mental disorder that is commonly characterised by attention problems, excessive activity or difficulty in controlling one s inappropriate behaviour, given his/her age. If ADHD occurs in an adult, the person might face significant issues in maintaining a job, managing time or being in a relationship.

In spite of being the most regularly studied and analysed mental issue in kids and teenagers, the cause, in most of the cases, remains unknown. The symptoms of ADHD might develop as one gets old. Apart from the common symptoms, the person might show signs typical to ADHD such as hyperactivity, inattention, impulsivity and disruptive behaviour as well as relationships and academic difficulties. The symptoms of ADHD need to last for about six months to be diagnosed as a disorder.

The typical management methods of ADHD include counselling or medicines, either used separately or in combination.

Behavioural Therapies: Some of the psychological therapies used are:
Cognitive Behavioural Therapy (CBT): Focuses on changing the thinking patterns of a person that ultimately alters the way he/she generally feels
Interpersonal Psychotherapy: IPT is a focused form of psychotherapy that involves symptomatic recovery and resolving interpersonal problems.
Social Skills Training
Family Therapy: Focuses on providing therapy to the individual as well as the family
School-Based Interventions
Parent Management Training
Medication: Stimulant medications are the more preferred forms of medications for ADHD. They have short-term effects on the symptoms of ADHD. One such example is that of Methylphenidate. Non stimulant medicines are administered for people who indulge in compulsive or recreational stimulant use. Examples include atomoxetine, guanfacine, bupropion and clonidine. Although these medications are usually safe, over dosage can cause side-effects and contraindications.
Diet: Modification in diet can prove beneficial for children suffering from ADHD. The benefits are usually confined to children having food sensitivities or those who are being medicated using ADHD medicines simultaneously.
