The relationship between intelligence and brain size, both among people and between various species, has never been precisely well defined. People often believe that their outstanding psychological capacities must mean that they are superior to all animals as far as brain size is concerned. However, it is not true since whales and elephants have much bigger brains than humans and humans have the same brain-to-body mass proportion as mice do.

Here are a number of ways by which the brain size can be determined:

Encephalization remainder: Since it would be against human instinct to admit loss and defeat, researchers have created a measure to determine the brain size called the encephalization remainder. It is the proportion of actual brain mass with respect to the anticipated cerebrum mass for the animal s size (based on the suspicion that bigger animals require somewhat less brain matter with respect to their size, compared to little animals). By this metric, human beings prove to be the best, with an EQ of 7.5 outperforming the dolphin's 5.3 and the mouse's 0.5.
IQ testing: Without a solitary and evident method for measuring intelligence, some improved tests like IQ (Intelligence Quotient) are by and large acknowledged as a moderately decent working device. IQ estimations are not without issues, and there is a great deal of criticism about their significance. IQ testing uses government sanctioned tests, for example, the WAIS III (Wechsler Adult Intelligence Scale). The normal IQ is somewhere around 90 and 110. The scores beneath the normal may demonstrate changing degrees of pathology, for example, marginal intellectual function, or mental hindrance of different severity. Over the normal range is regularly connected with knowledge, splendour, talent, or genius. However, as with computers of a few eras, size and intellect do not precisely relate. Present day portable computers weighing around one or two kilogrammes can store more data and perform a greater number of assignments than supercomputers from the 1980s that used to possess expansive structures. This is a contrast amongst quantity and quality. Numerous scientists now hold the view that it is not the whole brain, which is bigger in a human with a higher IQ, yet rather certain zones that are denser and might be bigger. A fascinating late revelation is that these ranges can be expanded in size and enhanced in usefulness during the course of our life.
NeuroplasticityIt refers to the dynamic procedure of repair and maintenance that our brains are continually experiencing. We are conceived with around hundred billion neurones, yet lose around two hundred thousand a day to a procedure called pruning. As we develop and grow, pathways in the brain that are not required are detached, and the neurones pass on. However, in a compensatory procedure, new neurones are delivered and more detailed associations are built up between neurones that are more dynamic. This is the procedure of de-cluttering, in which our brains develop to work at most extreme effectiveness. If you wish to discuss about any specific problem, you can consult a Neurologist.

Brain Size - How It Is Related With Intelligence?

Over time, we have caused tremendous harm to our immune system. Day in and day out, we have potentially risked our lives by being so casual with our health choices. But still, is it possible to leverage some of this burden and thus make our immune system stronger? What if we incorporate some healthy habits into our daily regime? What if we improvise on our diet? Take certain additional vitamin supplements perhaps? Make other lifestyle changes in the hope of achieving a near-perfect immune system?

What exactly is the Immune System?

The immune system in layman language can be considered as a protective cover of the human health system. We are surrounded by millions of pathogens (disease causing germs) that have the ability to enter into the body and cause damage to it. Here comes in the importance of the immune system, the body s natural shield against these pathogens.

How can you boost your Immunity?

You definitely cannot evade all the pathogens and get a top-notch, impeccable immune system, but you can at least try and listen to what your body has to say, and take steps accordingly.

The first and foremost protective measure can be to follow certain general good-health guidelines.

Do not smoke. There can be no compromise on this issue. Smoking or consuming tobacco in any form brings about a host of health complications; the most pronounced of them all is probably cancer. Smoking, in more ways than one, can spell real trouble for your immune system. So better cut down on your puffs or gear up to face the various medical banes of smoking.

Eat a diet which is rich in fruits, vegetables, whole grains and low in saturated fat. Some examples may include citrus fruits, green leafy vegetables such as spinach or lettuce, yoghurt, almonds, lean meat. Sipping on green tea thrice a day is a wise choice in this regard. These measures not only strengthen the immune system but also enhance the Immune System.

Drink plenty of water. Water keeps the body hydrated, the ultimate prerequisite for a strong immune system. It helps to flush out all the toxins and ensures that the cells get the optimum levels of oxygen. Drinking a glass of lukewarm water mixed with honey and lemon on an empty stomach after getting up in the morning can prove to be one of the best health choices that you can make for your body.

If you drink alcohol, drink only in moderation. Excessive alcohol consumption causes dehydration and it can deprive your body of the valuable immunity boosting nutrients. It also impairs the body s ability to fight off germs and infections.

Get adequate sleep. One reason behind stressing on the need to get adequate sleep is because it s so closely linked to the immune system. While you sleep, the body secretes certain hormones and substances which help better fight infections and diseases. This makes these hormones so vital and indispensable at the same time. So now you know what wonders can those 8 hours of sleep do to you.

Exercise Regularly. If you're looking for a safe and smart way to boost your immunity, regular exercise is the answer to it. But we are not talking about being an ardent, hard-core gym-junkie; rather exercising in moderate amounts would suffice. Cardiovascular exercises such as walking or swimming, performed 30-45 minutes a day, can prove to be very beneficial.

Including good hygiene habits in your daily routine, such as washing your hands properly, bathing and brushing your teeth daily, etc. can be useful as well. Good sanitary habits can be the most basic way to ward off infections at the germination stage. Keep a hand sanitizer with you all the time.

7 Healthy Habits That Keep Your Immune System Strong

You look your best when you wear a smile on your face. Everyone prefers a smiling face over a frowned one. Since we are talking about smiles, one can never underestimate the role that teeth play in the beauty of a smile. Dental hygiene and care is mandatory if you wish to secure your beautiful smile for years to come.

However, the global statistics for dental care suggests that we do not care enough for our teeth. 60-90% of children who are in school and almost every adult suffer from dental cavities. Dental cavities are pretty common nowadays. And yellowing of teeth can now be seen in almost every other person. It spoils the smile and makes people conscious. By ensuring a few dental care habits in your daily routine lives, you can avoid yellow teeth. Let us discuss the tips and tricks to avoid yellowing of teeth.
 
1. Say no to specific foods: Yellowing of teeth is caused by food choices including coffee, red wine, sodas, juices, sports drinks, white wine, coloured candies and other artificially coloured foods. It will help if these foods are consumed in less quantity and frequency as they are the major contributors towards discoloration of teeth.

2. Water after every coloured drink: Here is a habit that you must inculcate in your routine, whenever you consume any of the above mentioned food items. Post every drink or food intake which can cause tooth-staining, top it up with a glass of water. When you swirl or gargle the water in your mouth, you remove the acids that get accumulated in your mouth. It is one of the simplest preventive measures one can implement to avoid tooth stains.
 
3. Dental Hygiene: Our parents and dentists kept reminding us all the time to brush twice a day and gargle with water post every food intake but did we listen to them as kids? No we did not. Proper brushing, flossing and going for dental checkups at regular intervals are sure shot ways to keep your teeth healthy for majority of your lifetime. One must develop these habits quite early in life to gain benefits from it.

4. Whiten those Yellow teeth:  You might be at that stage of your life where inculcating the above mentioned habits won't do much good. The damage might already have been done. Your teeth are probably yellowish already and you have a history of dental cavities. In this 21st century, there are ways to whiten your teeth artificially with the many alternatives available in the market. One can opt for a solution, which can be done at home itself or go for a laser whitening which is now possible at a dentist clinic.
 
So there is still hope for those who are unable to share that smile with the world due to the yellowing of teeth. Nothing is irreparable here and the health of your teeth lies in your hand.

How to Avoid Yellowing of Teeth

Injuries are very common, especially head injuries are one of the leading causes of death and disability in adults. As per surveys conducted, 1.7 million people suffer from head injuries every year and this estimation is increasing day by day.

Head Injury is any trauma to head other than superficial injuries to face. It results in high morbidity & mortality. Head injuries are an important cause of loss of young people at their productive age.

Causes of Head Injury-

A head injury can occur due to many reasons. Some common causes of these head injuries are:

Vehicle accidents

Street fights

Fall from height

Child abuse

Symptoms of Head Injury-

A head injury is followed by various symptoms depending upon the intensity of the injury. Here is a list of the possible symptoms of brain injuries:  

Nausea and vomiting, fatigue or sleepiness, severe headache, confusion, amnesia,  loss of consciousness, seizures, loss of muscle control or paralysis in the part of the body controlled by the part of the brain that is affected, coma, dilation of the pupils and disturbance of vision, Cerebrospinal fluids might come out of the ears and nose, sometimes accompanied by blood, difficulty in breathing, low pulse rate, increase in blood pressure, difficulty in swallowing, loss of hearing, problems in cognitive functions.

Brain damage is a process, not an event. 80% are minor head injuries, 10% are moderate head injuries and 10% are major head injuries.

Management of Head Injury-

Diagnosis of a brain injury has to be detailed and very quick at the same time. It always comes under emergency cases. Some of the steps involved are:

Glasgow Coma Scale

Pupillary reaction to light

Brain stem reflex tests

Head to toe examination

CT scan of head is the initial study of choice. MRI Brain is helpful in cases of non-haemorrhagic contusions, diffuse axonal injury and deep lesions.

Surgical Indications

Head injuries with intracranial hematomas causing significant mass effect

Massive cerebral edema

Hydrocephalus

Infection

Precautions for Head Injury

Use Helmets- both riders

Use Seat Belts

Keep vehicle speed under control

Follow traffic rules

Take adequate precautions during trekking, diving

Take Away-

No head injury is minor enough to be neglected nor severe enough to be given up.

Head injuries take time to heal, but medical treatment along with neurosurgery can aid the process of recovery and also help a person to lead a healthy life in the future. Most young patients recover fully, while some older patients or patients with preexisting neurological conditions live with a degree of disability.



Head Injuries - All You Must Know!

Pelvic pain is generally referred to as the pain in the lower abdominal region. Pelvic pain might be acute, sudden, or chronic, recurrent, cyclical in nature. It may present as central or lateralized pain and might spread to the thighs and buttocks. Pelvic pain might be an indication that something is wrong with the internal reproductive organs located in the pelvic region such as ovaries, fallopian tube, uterus and vagina in which case occurrence of pain may be related to particular time in menstrual cycle.

Pelvic pain can be indicative of a pelvic infection or related to the pelvic bones/spine problems.

Also it may indicate that there is something wrong with the digestive system or urinary system.

Causes-

The causes are as follows:

Pelvic pain occurs commonly in disorders of the internal reproductive organs such as ovarian cysts or pelvic inflammatory disease (where in sexually transmitted bacteria spread through the reproductive organs and cause infection) or pain during ovulation.

Pelvic pain might also occur due to endometriosis (a form of disorder where the endometrial tissues that are located inside the uterus tend to grow outside the uterus resulting in severe pain), adenomyosis (a disorder wherein the endometrial tissues which line the wall of the uterus tend to grow within the uterus), , pelvic adhesions or ectopic pregnancy (when the fertilized egg gets inserted somewhere else other than the main uterine cavity),

Pelvic pain can occur due to bladder disorders, kidney stones, infection in the urinary tract, constipation, flatulence,inflammatory bowel disease, irritable bowel syndrome and chronic hernia.

It can also be a symptom in some cancers such as ovarian cancer, colonic cancer, advanced ovarian , endometrial and cervical cancer.

The following symptoms might occur along with pelvic pain:

Sustained pain in the hips and the groin

Sudden fever

Severe pain while urinating , passing stools or during sexual intercourse (dysparuenia)

Vaginal bleeding or vaginal discharge .

Blood in stool

Severe menstrual pain ( dysmenorrhoea)

Repeated instances of constipation or diarrhoea

Increase In pain with stress and physical movements

Investigations-

The Gynaecologist will do physical examination including bimanual internal examination. Also, complete blood count, urine for microscopy, vaginal swabs if discharge, stool examination. Ultrasound examination of the pelvis is an important investigation.

Treatment-

If the pain is gynaecological and depending on the cause doctors might suggest different therapies. In cases where pain is due to an ovarian cyst or endometriosis, doctors may prescribe birth-control pills. In cases of suspected pelvic infection, antibiotics are prescribed. Also, laparoscopic surgery might be advised in cases of acute pain due to cyst, endometriosis, or pelvic adhesions: for confirmation of diagnosis and excision or removal of cysts and endometriotic implants and division of adhesions respectively. In some cases of chronic pain, the gynaecologist may manage the case with inputs from gastroenterologist and pain consultant.

Causes and Symptoms of Pelvic Pain

If not for Edward Jenner, millions would have lost their lives to several diseases. The discovery of smallpox vaccination in the last leg of the 18th century marked the beginning of a new chapter of vaccination and became a lifesaver for the human race from fatal and limiting diseases like smallpox, polio, tetanus, rotavirus, etc.

World Immunization Day, observed each year on November 10, is celebrated to increase the awareness on getting vaccinations in time to protect individuals against preventable diseases. 

Immunization is very important to help create resistance and to prevent your body from getting infected with a number of diseases. Timely administration of vaccine can help protect both children and adults from major diseases. 

Why must you get vaccinated? Is it really important?
Yes, getting vaccinated is indeed important. It helps the body stimulate its own immune system to protect against subsequent infections and also prevents them from spreading through any form of contact.  Vaccination is more important for children because the immune system of a child developed through breastfeeding starts to diminish, once the development cycle of the new immune system begins.

Vaccinations are highly cost-effective and easy to access. According to the World Health Organization (WHO), timely vaccination has helped prevent up to three million deaths per year, but still, there are almost 19 million infants who are not given timely vaccinations.

Vaccination in India
The Universal Immunization Program (UIP) of India is one of the largest in the world in terms of the amount of vaccine given, the geographical area covered, and the number of people who have benefited from the program. The program has been in effect for more than 30 years. However, due to a lack of awareness among citizens, it has only been able to reach out to two-thirds of children all over the country. 

We should seek to achieve complete immunization of not only children but also of adults. Under the Mission Indradhanush, which was launched by the government in 2014, the program allowed all children of up to 24 months of age and pregnant women to get free vaccinations. 

Important vaccinations for children
The Indian Academy of Pediatrics recommends several vaccinations to be administered from 0 months to 10 years of age, the important ones being for polio, tetanus, rotavirus, typhoid, chickenpox, and MMR amongst others. It is essential for the parents to follow the immunization schedule and have the baby vaccinated against preventable diseases.

Vaccinations for adults
Vaccination is not just for children, but also for adults. All adults between the age of 20 and 30 should get a screening done for major preventable diseases like influenza, Tetanus, Hepatitis A, and Hepatitis B. An influenza injection should be administered once a year while a tetanus injection needs to be administered once every 10 years. 

Hepatitis A and B injections need to be administered during one's childhood. However, if adults aged above 19 and up to 49 years do not have any documentation of vaccination, it is strongly advised to take two doses of Hepatitis A and three doses of Hepatitis B.

Prevention is better than cure, and the most important gift that you can give your child and to yourself is good health. On this day, let's be aware of the importance of vaccination, and spread the same. Get vaccinated, stay healthy, and happy!
