Nailed it

When you are young, fingernails and toenails give no trouble at all. (They may just be a bit dirty). With advancing age, however, they become brittle, hard, fall off or develop infections and become painful. Suddenly, you are forced to notice your nails!
Healthy nails are usually smooth and light pink in colour. Blue nails occur when there is a lack of oxygen in the blood (heart and lung disease). Nails can turn black in vitamin B12 deficiency. A horizontal depression or discoloration can develop across the nail due to illness, antibiotics or chemotherapy. The line becomes prominent as the nail grows out and then gradually disappears. Nails may grow brittle if there is anaemia and can also become spoon shaped. The opposite, a bulged out, parrot-beak like club-shaped nail is seen in chronic obstructive airways disease. Splitting and fraying are associated with hypothyroidism and psoriasis.
Fingernails grow faster than toenails. The rate of growth depends on health, heredity and sex. Growth slows during illness and with increasing age, but at the same time, the nails become tougher. They are then more difficult to trim.
In prehistoric times people had to bite their nails to trim them but today it is a social no-no. Biting in itself is harmless but it can cause secondary bacterial infection of the skin around the nail. It can cause and perpetuate worm infestation. It can transmit flu viruses acquired from contaminated surfaces directly to the mouth. Bitten down nails may work against you in job interviews. It is a habit that is arises out of lack of impulse control, and is perpetuated by stress.
Most important, a close examination of the nails can reveal other disease processes such as iron deficiency (anaemia), vitamin B12 deficiency, diabetes, kidney and liver disease and even infection of the heart valves (endocarditis).
In older people (particularly those who have high blood sugar) an infected ingrown toenail (usually the big toe) is a common problem. This occurs when toenails are trimmed too short, blades or knives are used instead of nail cutters or if the edges of the nails are picked and torn.
If there is no diabetes, an ingrown toenail can be treated at home by soaking it in warm salted water for 10 minutes and placing a cotton ball soaked in antibiotic ointment under it.
Nails are also prone to fungal infections. This destroys the nails and gives it an “eaten away” appearance. Topical ointments are not very effective. Medicines have to be taken orally until the infection resolves and a healthy nail grows out. This takes anywhere from three to six months. Medical conditions like psoariasis may mimic fungal infection. A proper diagnosis is essential before embarking on treatment.
In our climate, slippers or open-toed sandals are better than shoes. If shoes have to be worn, they should fit properly. Shoes that you wear every day should have plenty of room around the toes so that nails do not hit the end of the shoe. They should also not be too loose as your feet will slide forward while walking or running and hit the end damaging the nails.

exercise for children
Teach kids to stay fit
| ||
| ||
Summer vacations have started. Earlier children would “go to the grandparent’s village” for a month of playing in the fresh air and sunshine. It was a welcome annual ritual, an antidote to the structured drudgery of school days.
This is no more the case. Now grandparents too live in towns or cities where there are few playgrounds. The heat makes everyone lethargic; summer sports coaching is available but inaccessible to the majority of children. The stress on academic excellence often means that from a young age children are sent to coaching classes during the holidays.
Parents say “my son /daughter plays everyday.” They mean computer games, video games or running around in the house or apartment complex. Others bemoan the number of hours spent watching television. This is often coupled with unhealthy snacking -- packaged foods washed down with sweetened aerated drinks. Naturally the children gain weight. But, the weight gain is unhealthy and the child is over and above the recommended weight for age. The formula (age +3)X5 = ideal body weight in pounds. This divided by 2.2 gives the weight in kilograms. Alternatively the height in metre squared multiplied by 23 provides an approximate value of the ideal body weight.
The extra fat is usually deposited in the abdomen producing an unsightly paunch. The accompanying fat thighs mean the children look knock kneed and have an ungainly waddling gait.
An hour is the minimum recommended amount of exercise required for physical and mental health of children. Today, the majority of children and adolescents do not get the required one hour of aerobic activity (running, swimming or cycling) a day either during school days or during the holidays. Their muscles are often weak and flabby. As sunlight exposure is minimal, their bones too lack strength, predisposing them to calcium deficiency and osteomalacia in adult life. Studies have shown that around 70-80 per cent of children and adolescents in India are vitamin D deficient despite our abundant sunshine.
Obesity and vitamin D deficiency are two of the factors that predispose to the development of diabetes. The lifestyle and habits that result in progression to diabetes are established in childhood.
One out of five Indians is either frankly diabetic, prediabetic or has gestational diabetes (diabetes during pregnancy). Many of these people are unaware that they have a problem. They go about their daily activities without any symptoms at all. Some may feel tired, notice extra hunger or thirst, have frequent visits to the toilet, lose weight, or develop urinary tract infections, boils, skin lesions that do not heal, fungal infections on the skin or vagina or urinary tract infections.
It is important to recognise a predisposition to develop diabetes. Children who are inactive and obese grow into adults who are the same. They learn by observation. They watch sedentary adults (often their role models) in the family, snacking and watching television assiduously. During adolescence, boys may develop breasts and a paunch. This makes them self-conscious and often undermines their self-confidence. In girls, hormonal imbalances develop. The periods become irregular. Attractive girls grow into teenagers with pimples, a hairy face and scanty hair on the head.
Urgent action is needed now, when parents and children have time and energy and are not under the stress of examinations.
• Search for a government sports complex near your home. These are well run and provide training in a variety of sports. Even if they do not express an interest and show a reluctance to go, eventually interaction with athletic peers will cultivate a competitive spirit and interest in the sport.
• If nothing is available, get up at 5AM, wake up the children and ask them to run/walk outside the house for 40 minutes. The traffic is usually not heavy at that time but supervision is needed. You cannot really sit in the house and tell children “go and run.”
• Appropriate footwear is needed. Shoes and socks need to be provided. Running in slippers and sandals is not advisable as it predisposes to injuries of the foot.
• Flexibility and core strength is important. This prevents injuries and backache, arthritis and knee pain in adult life. Yoga can be learnt and practiced at home. Martial arts training is also a good alternative. Especially for girls, it provides flexibility, confidence and personal security.
Although you may have a strong family history of diabetes, and you may eventually succumb to your genes, regular exercise, and maintenance of a healthy lifestyle and ideal body weight with good muscle mass will go a long way in delaying the onset of the inevitable. It is never too late to start, even if you are technically past your childhood.

sex and gender
The third gender
| ||
| ||
The terms sex and gender are often interchanged, even in official forms, under the erroneous impression that they mean the same thing. Actually, “male or female” is the sex, “masculine or feminine” the gender.
Gender is the self-identified perception of the individual. This can be different from the sex medically assigned at birth. People can choose to identify themselves as male, female or the “third gender.”
Most people are “cisgender” or comfortable with the sex they are born with. One in 1,000 people exhibit a dissociation between the genetic sex, psychological gender, and social sex. They may be uncomfortable with the roles they have to play in society.
Sometimes the physical attributes signifying a sex get interchanged. A woman may be hairy with a deep voice and a man may have scanty facial hair and a high-pitched voice. This makes it difficult for the person to psychologically identify with their attributed sex. One in a hundred persons may have intersex characteristics.
This may result in them trying to change the sex through entensive surgery. Men who have changed themselves into women do not menstruate and cannot have children. Women who transform themselves into men usually have their uterus and ovaries removed. They can also call themselves the “third sex,” neither male nor female. They can just “cross dress” as a person of the opposite sex without undergoing surgery. They can take hormones for masculinisation or feminisation.
A woman may develop a deep voice, facial hair and male pattern baldness. If these changes occur in adolescence, they may have difficulty determining which sex to identify with. This is increasingly common with the widespread occurrence of PCOS (polycystic ovary syndrome). It may occur as a result of tumours of the adrenal gland or ovary or as a side effect of medication.
In men too, facial hair may be scanty, there may be breasts and a high-pitched voice. This can be the result of liver disease, tumours or medication.
Psychological and social confusion may be created in the minds of children because of cross dressing by parents. Boys dressed as girls is a social “no no” for whatever reason. Girls dressed in pants and shorts, on the other hand, is totally acceptable. They usually wear feminine accessories such as earrings, necklace, bangles and hair clips.
The Supreme Court of India, in a landmark judgment, has recognised the existence of a third gender. You can “declare” yourself any gender (male, female or the third). No surgical procedure needs to be performed nor any medical or legal proof provided.
If we can declare our gender as whatever we are comfortable with, it opens up many questions. Does it mean that men who perceive themselves as women can occupy the “reserved for women areas”, participate in sports in the female category and get jobs in the women’s quota? Or, is everything going to be changed into “male, female and NOTA” (the third gender)?

cramps
Cramped up
| ||
| ||
We humans can perform highly complex and coordinated actions. We have muscles under voluntary control, which obey commands relayed by the brain. Movements are smooth and synchronised as opposing groups of muscles work in tandem.
However, muscles occasionally fail to obey the commands of the brain. They contract and go into a painful “spasm”, refusing to relax. The agonising discomfort prevents further movement. After a few minutes (which seem like an eternity) the muscle relaxes. The cycle may or may not recur. If cramps occur during a sport, the competitor may be massaged on the field or led off it. If they occur in the night, the pain wakes the person up.
About 95 per cent of the population experiences cramps at some time in their life. They occur in all age groups (including children) but become more common with increasing age.
Diagnosing a cramp is not difficult. The sufferer knows he has developed a cramp. The severe pain makes him stop the activity or wakes him up from sleep. The muscle is tight, sore and a hard tender knot can be felt. Although the cramp disappears in a few minutes, the soreness may persist for days.
Cramps can occur due to:
• Fracture of the underlying bone. Overlying muscles tend to go into an unrelenting protective painful spasm.
• Overuse injury like in writing, typing or computer use. The fingers assume abnormal painful positions from which they cannot voluntarily be straightened.
• Excessive sweating because of the heat — with or without exercise — which depletes the body of salt (sodium).
• Electrolyte imbalances and shift of body fluids due to liver (cirrhosis) or kidney disease (renal failure) or the hormonal changes of pregnancy, with hyperventilation or vomiting.
• Withdrawal from alcohol, sleeping tablets and anxiety agents like valium in addicts.
• Deficiencies of the B group of thiamine (B1), pantothenic acid (B5), and pyridoxine (B6) and vitamin E. The exact mechanism is not known but these vitamins are thought to stabilise the nerve membranes
• Medications such as diuretics, statin group of drugs raloxifene, parkinson’s disease medications, nifedepine, asthma medications like terbutaline and ventorlin.
Cramps usually occur due to the levels of minerals and electrolytes in the body going “out of sync”. This is because unbalanced or low levels (particularly of sodium, calcium or magnesium) cause hyper excitability of the nerve endings going to the muscles. They are unable to obey commands from the central areas of the brain to relax.
Low levels of calcium and magnesium can occur in pregnancy and with increasing age unless they are supplemented. Calcium can be taken as tablets. Supplements work well provided the level of vitamin D3 in the body is adequate. Aerobic physical exercise helps ingested calcium get into the system. The safest way to supplement magnesium is with an adequate intake of greens, grains, meat and fish, bananas and nuts.
Sometimes the calf muscles pain when walking. After a period of rest the pain disappears and walking can be continued. This is not true cramps but claudication. It occurs as a result of inadequate blood supply to the muscle. It requires medical evaluation.
Cramps can usually be stopped if the muscle is stretched in the opposite direction. For calf cramps that means placing both feet flat on the ground, keeping the leg straight and rocking back on toes and heels. Alternatively you can stand half your height distance away from a wall, stretch arms out and balance against the wall. If still in bed and unable to move, keep the feet straight and stretch the toes towards the head. For “writer’s cramp”, place hands flat against a wall with fingers facing downward.
Gently massage the cramped muscle. Then apply warmth with a heating pad or hot water. This will help the muscle to stay relaxed. If the cramp is associated with fluid loss, water and electrolyte replacement is needed. Salted buttermilk, lime juice, commercially available electrolyte solutions, or ORS (oral rehydrating solution) packets can be used. Caffeine containing beverages (coffee, tea and colas) aggravate dehydration.
Exercise, (even in the elderly) should start and end with stretching. Hydration should be adequate. The amount of water required depends on the intensity of the exercise and the weather. If thirst develops it means that dehydration has already set in. Older people and young children do not experience appropriate thirst.
Muscle cramps usually disappear on their own and do not require specific medication. If they occur frequently without exercise or dehydration and are accompanied by severe discomfort, and skin colour or texture changes, then they may be due to some other disease process. This requires medical evaluation.
