What causes palpitation?

Palpitation (pounding heartbeat, harder and faster than normal) could be due to extrinsic causes like ingestion of a stimulant (coffee, tea, cola drinks, chocolates, some medications, etc.) and/ or cigarette smoking, or due to intrinsic causes like coronary or heart valve diseases. The person feels the heart thumping in his/ her chest which could lead to some degree of discomfort and anxiety. When this happens regularly, in spite of abstinence from the extrinsic causes listed above, prompt medical consultation is recommended.

Are body moisturizing lotions safe?

Yes, in general, hand and body lotions in the market are safe. The frequent (two or more times a day) use of hand and body lotion is recommended because our skin needs moisture to keep it comfortable, healthy and as young looking as possible. Caution: some people may be allergic to some of these commercially available skin moisturizers.

Does diabetes cause blindness?

Most definitely, especially among persons whose diabetes is untreated, poorly treated or simply brittle and hard to treat. The blindness is due to what is termed diabetic retinopathy. A significant number of blindness in the world today is caused by diabetes. Once the diagnosis of diabetes mellitus is confirmed, prompt and appropriate therapy should be instituted. The diabetic should be disciplined enough to religiously follow the prescribed medical regimen if the complications of the disease, like blindness, leg gangrene, etc. are to be prevented.

Can hydrogen peroxide be used for gargling?

Yes, hydrogen peroxide could be used for gargling, but ask your dentist first since he/she knows your dental condition better and can advise you accordingly. Hydrogen peroxide, together with sodium fluoride and other common ingredients (like triclosan) in toothpastes, help prevent tooth decay, gingivitis (inflammation of the gums), tartar and plaque formation, and halitosis

(bad breath). Hydrogen peroxide is a substance that is incorporated in many toothpaste preparations in the market today. Baking soda is another. For children, the anti-plaque and antigingivitis effectiveness of toothpaste are still not proven.

What is cardioversion?

Cardioversion, as the term suggests, means converting the heart rhythm from an abnormal one to a socalled normal and regular sinus rhythm, either by medications or by electrical (shock) “zapping.” The term is most often used to imply electrical cardioversion. This is done when the type of abnormality of the rhythm of the heart is one of the dangerous forms that adversely affects the vital signs of the person or one that could potentially cause cerebral emboli (blood clots from within the heart) traveling to the brain resulting in stroke. The two paddles (“zappers”), held one in each hand of the cardioverting personnel (a physician, a nurse or a medical technician) are applied on the mid-chest of the patient and the heart is “electrically shocked” to a normal rhythm or to a safer, more benign form of irregularity. In some persons with a heart disease, it may not be possible to convert the rhythm to a perfect sinus rhythm. In these cases, the goal is to convert the rhythm to an acceptable more benign rhythm. Does surgery make cancer spread?

No, this is a myth. Doing surgery or “opening the patient up” does not cause metastasis (spread) of the cancer. In general, cancer proliferates rapidly to invade surrounding tissues and distant organs. The misconception resulted from the refusal of patients suspected or confirmed to have cancer to be operated on early when first advised and had delayed the surgery so much that the malignant tumor had already spread beyond help before acceding to have the operation. So, when the surgeons operated on them that late, invariably the cancer had already spread all over. When the patients soon expired, people blamed the surgery as the cause of the spread. Today, almost everybody knows that prompt detection
