Dengue Fever

By
It is the familiar story line of a small David felling the giant Goliath to the ground; this time it is the small Dengue virus challenging the might of the government and bringing it down to its knees.
Dengue is having a free run this autumn, thank
s to the rampant water logging and unrestricted breeding of mosquitoes.
Recognising Dengue Fever (DF): It is a viral infection transmitted by mosquitoes and presents as a sudden febrile illness of 2-7 days’ duration, with 2 or more of the following:
1. Headache
2. Pain behind the eye balls
3. Severe body aches
4. Pain in the joints
5. Rash
One of the main concerns in Dengue is the fall in platelet counts from its normal range of above 150,000. Platelets play a vital role in preventing or stopping bleeding from small blood vessels. Infusion of platelets is required only if they drop to below 20,000 or when there is active bleeding. Remember transfusions have their own risk of transmitting other infections, of allergic reactions, and their effect lasts barely a few hours.
The other concern is shock. Dengue sometimes causes fall in blood pressure due to leakage of plasma from capillaries with loss of blood volume. The Haemoglobin level paradoxically rises and urination may become less. Some patients show liver involvement (Serum ALT/AST, Bilirubin) or kidney dysfunction (increase in serum creatinine). These usually settle down with good intake of fluids and calories.
Tests for Fever: It is important to remember that all fevers may not be due to other infections such as Enteric Fever (Typhoid), malaria, and common flu that appropriate blood tests will show. It is important to get them done if fever persists for more than 2 days, because Dengue being a viral illness has no specific medicines, while typhoid and malaria have.
Tests should include Haemoglobin, PCV, white blood cell and platelet estimations, and tests for malaria, typhoid, and Dengue.
When to worry: If you have contracted Dengue, lie in bed and take rest for at least a week, drink lots of liquids (water, juices, soups, nimboo paani or ORS), take paracetamol tablets (up to 3 a day), avoid aspirin and ibuprofen as they may trigger bleeding, apply balms on your head and listen to soothing music. Consult your family physician but do not panic. Remember that there is no specific medication for Dengue and yet recovery is the rule.
Critical phase: Contrary to popular belief, the danger phase in dengue is not the 1st 2-3 days of high fever, but around the 5th to 7th day, when the fever begins to settle. Many people who are in a hurry to get back to their normal lives often crash during this phase with low BP and shock. It is therefore crucial to relax at home for a couple of days more.
And do what I am sure, the government is doing; tell yourself “This phase too shall pass”.

The Doctor’s Dress

By
The familiar white coat worn by physicians as their distinctive dress for over 100 years, has started generating  murmurs  of controversy. It is not uncommon to find the blood pressure to be higher when measured by a white-coat-wearing-doctor in the hospital or clinic than the readings obtained at home by relatives.  This is due to the anxiety that the white coat and the hospital setting evokes in patients, and has been termed “White Coat Hypertension”. Mature clinicians often routinely subtract a few points from these measurements when entering records in case charts or calculating the dose of anti-hypertensive medications to be prescribed. The white coat scares children too.  Kids often express their dislike for this dress by crying and screaming and by denying access to their bellies or chest for examination by paediatricians in this attire. Many pediatricians across the world have folded up their white coats and taken to informal colourful dressing to...

Food Fads in Liver Disorders

By
In an attempt at trying to do well to those they love, spouses and parents often enforce diets on patients of liver diseases that often turn out to be detrimental. The commonest food fad is pale insipid boiled cabbage being doled out to nauseous patients suffering from hepatitis that makes them puke even more.  The liver, in a way, is a buzzing manufacturing unit that requires lots of energy to keep its multiple functions going. And it derives all this from the food we eat. During disease, such as during an attack of jaundice, when many of the liver cells get killed, the liver attemptsdamage control by trying to regenerate quickly. For its cells to multiply however, it requires a generous supply of energy that comes from carbohydrates, and protein, the building block for its cells and tissues. Boiled green vegetables unfortunately have neither of these. Hence the situation often progresses to that of a starved liver unable to recuperate due to cut-off food suppl...

Teaching and Learning – is there a trick?

By
One of the big mistakes that we as parents and teachers often make, and that could stifle the mental development of our children, is to treat them as just small adults! In fact, it is this attitude of grown-ups that could be leading our next generation to become stereotyped conformists rather than original thinkers and innovators. And if we intend to drive home health messages and inculcate healthy habits we need to tailor our efforts to their cognitive potential. That children indeed think and discover the world differently was first noticed by a Swiss scientist Jean Piaget in the early 20th century. He studied his own three children grow and was intrigued by how they behaved, played games and learnt at different ages. With further observations and experiments, he propounded the theory of ‘cognitive development’, placed great importance on the education of children and is hailed even today, 30 years after his death, as a pioneer of the constructive theory of knowing.  He...
