Medical facts and myths


    ‘While they have the right to get infected or even kill themselves, they do not have the right to spread the deadly virus to others, especially to the vulnerable elderly.’

    COVID-19 updates

    RECENT studies have shown that a well-fitting facemask significantly protects the person wearing it, and not only persons nearby, as previously thought. Rumors that facemasks are useless are fake news, medically unfounded. Together with limiting travels to essential ones, avoiding crowd, social distancing, and good personal hygiene, wearing a facemask dramatically lowers the risk of getting infected with the SARS-Cov2 virus, the cause of COVID-19. Prevention is the key. There is no treatment yet.

    Since those exposed to COVID-19 and carriers of the virus may be asymptomatic (early stage) and not even know they are infected, they could spread COVID-19 without realizing it. This is the medical rationale for those five recommended measures listed above. Let us not accidentally kill some people by our carelessness, indifference, and neglect. For most seniors with medical issues, getting COVID -19 could be a death sentence.

    Since the virus enters through the moist mucosa (eye conjunctiva, nasal mucus membrane, and oral cavity), these three must be covered properly. Exposing the nose is dangerous. The mask must fit snugly all around and should be worn whenever outside the home.

    New waves of COVID-19

    People are wondering why new waves of COVID-19 have appeared and some cities are once again imposing mask mandate and lockdowns. The simple answer, which should be obvious, is people’s lack of discipline, indifference, non-compliance, and carelessness. This is more prevalent in democratic countries, where irrational people demand to do whatever they want, regardless of the societal consequences. They only care for themselves. In the case of this pandemic, they do not even care for their own health, refusing not to wear masks, do social distancing and avoiding crowds. While they have the right to get infected or even kill themselves, they do not have the right to spread the deadly virus to others, especially to the vulnerable elderly. Much less kill them, even accidentally or incidentally. Anyone contributing to or causing the death of another person could be considered negligent homicide.

    Betadine gargle

    Current clinical observations revealed that povidone iodine (Betadine) topical antiseptic used in wound care is effective as a mouth rinse against SARS-Cov2 virus (COVID-19), better than the various mouth washes on the market and better than hydrogen peroxide rinse. Ready-made Betadine mouth rinse for instant use and 10% Betadine solution are available in most pharmacies and on The DIY dilution recommended by Harvard graduate Dr. Sandra L. Cremers is 1:1 (equal parts of 10% Betadine and water = 5%), gargled 2 to 3 times a day.


    Two vaccines against COVID-19, using the same mRNA technology (Pfizer/BioNTech – (90% effective in 60,000 clinical trial), and Moderna – (94.5% effective in 30,000 clinical trial), are expected to be approved by the FDA for distribution by the end of this year for healthcare workers, the military, police, firefighters, other first responders, and for seniors and those with compromised immune system. The general public will get the vaccines after January 2021. How long the protective immunity these vaccines will provide has yet to be determined by clinical observation and follow-up. There appears to be no safety concerns or serious side-effects found with either of these two vaccines. They will certainly be a game changer in our battle against COVID-19 worldwide, where the total cases as of February 17, 2020 was almost 55.7 million and deaths nearly 1.4 million. In the Philippines, almost 411,000, with about 8,000 deaths; and in the United States, almost 11.6 million, with more than 253,000 deaths.

    Men’s sweat good for women

    Don’t laugh. This is true. Biologists at the University of Pennsylvania found that men’s perspiration has beneficial effects on women’s mood, reduces stress and induces relaxation.

    It even has an effect on a woman’s menstruation. Blood tests revealed a rise in the level of reproductive luteinizing hormone, which normally surges before ovulation. It is true then that when women say they love the scent of their man, it is genuine and scientifically founded. Guys, this does not mean we have to stop taking showers!

    Viagra for Women?

    Viagra has worked most effectively for men with erectile dysfunction since it was introduced by Pfizer and approved by the FDA on March 27, 1998, inspiring the quest for a similar drug for women. Forty three percent of women have sexual dysfunction compared to 31% of men, where cigarette smoking has been found to be a culprit of impotence. The most common complaint among these women (33%) is lack of desire for sex. But while men’s problem is more physical (inability to have effective erection), women’s is more psychological, more complex, since the more significant sexual organ of the females is in between their ears, and not in between the thighs like the males.

    Flibanserin (Addyi), a drug developed as antidepressant, has been approved by the FDA as a therapy for low sexual desire in premenopausal women. When taking this one-a-day pill, abstinence from alcohol is a must, since severe drop in blood pressure, dizziness, fainting can result from the combination. The drug should be stopped if it is not effective after eight weeks. Bremelanotide (Vyleesi) is an injectable drug approved by the FDA to increase libido in premenopausal women, given 45 minutes before anticipated sexual activity, not more than one dose a day, not more than eight times a month. Do a due diligence on this subject and discuss this treatment with your gynecologist.

    The myths about safe sex

    The following are myths: A woman is guaranteed 100% not to get pregnant IF: (1) penetration is done only a few times without completion of intercourse; (2) withdrawal is done before ejaculation; (3) coitus is done during the “safe” period; (4) sex is done during menses; (5) the woman did not have orgasm during sex; (6) the lovers drink wine before sex; (7) aspirin is inserted into the vagina as contraceptive; (8) the woman is on top during the act; (9) the man uses any plastic wrap in the absence of, and in lieu of, a condom; (10) the man already had sex with another woman, or had masturbated, an hour or so earlier; (11) oral sex preceded normal intercourse; and (12) the woman douches immediately after sex. These are all myths and cannot be relied upon to prevent pregnancy. Only total abstinence or the use of an intact condom, or birth control pills under medical supervision, can prevent pregnancy.
