Chicken pox


Chickenpox

It is a viral disease caused by exposure to the varicella zoster virus.

The virus spreads through air-borne droplets when an infected person coughs or sneezes. It also spreads by direct contact since the lesions contain infectious fluid.

Symptoms:
The rash first appears over the face, scalp or trunk.
The rash initially consists of red/purple coloured bumped lesions which evolve into lesions filled with a clear fluid.
The lesions then form a crust after 4-5 days of appearance.
The crusts fall off after a week or two.
The rash is itchy and cause irritation.
Other symptoms: fever, nausea, anorexia, body ache, vomiting etc.

Complications:
Secondary bacterial infection affecting the skin lesions is the commonest complication among children.

Treatment:
Paracetamol can be given to control fever.
Itching can be controlled by calamine lotion.
Nails should be trimmed to reduce the damage done by scratching.
The affected child should be bathed daily.

Vaccination

A vaccine containing a live attenuated strain of varicella is available.

Quit smoking


Smoking
Smoking is a major cause of heart and blood vessel disease. Overall, smokers experience a 70 percent greater death rate from heart and blood vessel disease than non-smokers; and heavy smokers (two or more packs per day) have a death rate two to three times greater than non-smokers. Inhaling cigarette smoke produces temporary effects on the heart and blood vessels.


Quit smoking

No cigarettes are considered safe. Many smokers who have switched to low tar and low nicotine cigarettes smoke more or inhale more deeply to make up for the decreased nicotine. By inhaling more deeply, smokers may increase their risk of disease.

Once you quit smoking, the risk of heart and blood vessel disease gradually decreases.

High blood pressure


High blood pressure

Blood pressure is the force of your blood against the walls of your arteries. Normally, arteries are muscular and elastic. They stretch and contract as blood goes through them.

Your blood pressure consists of two numbers. The top reading is the systolic pressure – when your heart is contracting, the bottom number is the diastolic pressure – when the heart is relaxing. If your blood pressure consistently runs 140/90 or more, you may have hypertension (high blood pressure).

High blood pressure may increase the possibility of strokes due to damage to the blood vessels that lead to the brain: it may cause kidney damage, congestive heart failure: and may increase your risk for coronary artery disease.
