    Menstrual blood as source of stem cells?

    Sunday, December 2nd, 2007

    Stem cells have been considered as promising breakthrough as cancer treatments. Potential sources such as skin cells, bone marrow cells, etc., have been widely researched. It seems that there is addition to these sources as researchers from a biotechnology firm in Arizona discovered the endometrial regenerative cells.

    Ethical issues have been raised regarding this new form of medical treatment.

    Stem cells come from two main sources: embryos or adult tissues. Embryonic stem cells can give rise to virtually any cell type in the body, but they are controversial because conventional procedures for obtaining them involve the destruction of an embryo. Adult stem cells, such as those found in bone marrow, do not pose the same ethical concerns, but they have limited powers and collecting them can require invasive procedures.

    While the new technique of reverting skin cells to an embryonic stem cell-like state promises to overcome the ethical dilemmas, this approach could come with safety concerns that make the cells too risky for use in humans. The technique for converting the skin cells involves using viruses to insert several genes, one of which is known to cause cancer.

    Menstrual stem cells could turn out to be a happy medium between embryonic and adult stem cells, providing an ethically acceptable alternative that is readily accessible and appears to give rise to most of the major tissue types in the body.MSNBC


    Advantages of the menstrual stem cells include its easy collection and vast availability, not causing any harm or pain to the donor and it can be collected for more than 35 years, from 12 years old to 47.

    The researchers are currently conducting animal studies and an approval from the FDA for human studies is still needed to complete their investigation.

    Can we bring back life from the dead?

    Saturday, September 29th, 2007

    Philadelphia doctors say “yes!”

    A new interesting treatment is being tested by Philadelphia doctors to restore life and bring people back from the dead.

    A cardiac arrest patient was saved by the new experimental treatment of chilled saline injection. Cooling pads are then wrapped around a patient. The body temperature is normally 98 degrees, but cooling brings it down to 92 degrees. Doctors keep it there for about 24 hours. This process is called intentional hypothermia. Accordingly, it decreases cellular injury when the cells are deprived of oxygen, so with less injury we are able to do a better job of getting people back.

    The cooling therapy needs to be faster, so the doctors are developing a slushy type saline that contains ice particles. It would be injected into the blood stream to quickly reduce body temperature.

    The experimental cooling treatment at HUP can only be used on certain patients. But doctors expect it will eventually become a critical standard of care for saving lives.

    How to Prepare for the August 2007 Philippine Licensure Exam for Physicians

    Wednesday, July 25th, 2007

    The August 2007 Philippine Licensure Exam for Physicians is fast approaching. How do you prepare for it? Here are few tips you can follow:

    1. Follow these tips from The House Officer’s Survival Guide: Rules, Laws, Lists and Other Medical Musings, by Lawrence Martin, M.D for It is written for doctors in training, but will also be of interest to medical students, and practicing physicians who must take recertifying exams.

    2. Get good reviewers and focus on one study material per subject area. This way, you can concentrate more and it won’t take more of your time. Of course you will still need the “big” text books for clarification of some points you can’t understand while taking the review.

    3. To attend to review center or not? Some successful passers do not advocate attending review center while others do. It would depend on the person’s preference.

    4. Follow your own schedule and not of others. If you can’t make an overnight review, then don’t. Because you might end up sleeping all day the next day. An overworked mind also fails to function sometimes. If your study hours is only 4 hours, don’t force yourself to study for longer number hours. Chances are, you will not retain most of them. If you need to extend your study time, you can slowly increase the time day by day so your body can adjust well to the new “stress.”

    5. To study alone or attend on a group study? Again this will depend on your preference. If you can function well with a group then organize a small discussion group. Some prefers to study alone so they can concentrate more with less annoyance.

    6. Do not cram!

    7. Most importantly, pray!

    Schedule for the Exam:
    Aug 4 (Saturday)
    8am-10am (Biochemistry)
    11am-1pm (Anatomy, Histology, Neuroanatomy)
    2pm-4pm (Microbiology, Parasitology)

    Aug 5 (Sunday)
    8am-10am (Physiology)
    11am-1pm (Legal Medicine, Medical Jurisprudence)
    2pm-4pm (Pathology)

    Aug 11 (Saturday)
    8am-10am (Pharmacology and Therapeutics)
    11am-1pm (Surgery, Ophthalmology, ENT)
    2pm-4pm (Internal Medicine)

    Aug 12 (Sunday)
    8am-10am (Obstetrics, Gynecology)
    11am-1pm (Pediatrics and Nutrition)
    2pm-4pm (Preventive Medicine and Public Health)

    Good luck to all incoming doctors!

    The new ‘plastic’ blood

    Sunday, June 24th, 2007

    Scientists continue to find ways to deliver better health care to patients; one new innovation is the availability of artificial blood, so called because it is made up of plastic molecules that have an iron atom at their core, like hemoglobin, that can carry oxygen through the body. This new discovery could help to substitute for blood, which is not always readily available in cases of emergencies, especially pointed out was its huge advantage in war zones.

    Besides its storage advantage; it is light to carry, does not need to be kept cool, it can be sterilized, and can be kept for longer, the new artificial blood has its advantages over human blood as pointed out in this WikiPedia article.


    1. Donations are increasing by about 2-3% annually in the United States, but demand is climbing by between 6-8% as an aging population requires more operations that often involve blood transfusion.

    2. Although the blood supply in the US is very safe, this is not the case for all regions of the world. Blood transfusion is the second largest source of new HIV infections in Nigeria. In certain regions of South Africa as much as 40% of the population has HIV/AIDS, and thorough testing is not financially feasible. A disease-free source of blood substitutes would be incredibly beneficial in these regions.

    3. In battlefield scenarios it is often impossible to administer rapid blood transfusions. Medical care in the armed services would benefit from a safe, easy way to manage blood supply.

    4. Great benefit could be derived from the rapid treatment of patients in trauma situations. Because these blood substitutes do not contain any of the antigens that determine blood type, they can be used across all types without immunologic reactions.

    5. While it is true that receiving a unit of transfused blood in the US does not carry many risks, with only 10 to 20 deaths per million units, but blood substitutes could eventually improve on this. There is no practical way to test for prion transmitted diseases in donated blood, such as Mad Cow and Cruetzfeld-Jacob disease, and other disease could emerge as problems for the blood supply, including Smallpox and SARS.

    6. Transfused blood is currently more cost effective, but there are reasons to believe this may change. For example the cost of blood substitutes may fall as manufacturing becomes refined.

    7. Blood substitutes can be stored for much longer than transfused blood, and can be kept at room temperature. Most hemoglobin-based oxygen carriers in trials today carry a shelf life of between 1 and 3 years, compared to 42 days for donated blood, which needs to be kept refrigerated.

    8. Blood substitutes allow for immediate full capacity oxygen transport, as opposed to transfused blood which can require about 24 hours to reach full oxygen transport capacity due to 2,3-diphosphoglycerate depletion.

    However, these advantages do not guarantee of a problem-free transfusion. This blood replacement products can interfere with blood tests, are more quickly removed from the body, and are less efficient oxygen carriers. Their use, once approved, will probably be limited to emergencies involving severe blood loss caused by serious accidents.

    15 Ways to Make Your Food Safer

    Friday, June 22nd, 2007

    WebMD lists 15 ways to make your foods safer:

    1. Consider your source. Eating locally grown food is becoming more popular, but that doesn’t necessarily mean it’s safer than supermarket produce.

    2. Map your supermarket route. Don’t cruise the store aisles aimlessly. Gather nonperishable items first, fresh or frozen goods last. That strategy minimizes the time that perishable goods sit in your shopping cart instead of in a freezer or refrigerator.

    3. Be choosy. Select fresh produce that isn’t bruised or damaged. Check that eggs aren’t cracked. Look for a clean meat or fish counter and a clean salad bar. Don’t buy bulging or dented cans, cracked jars, or jars with loose or bulging lids. If fresh-cut produce (such as half a watermelon or bagged salad mixes) is on your shopping list, choose those that are refrigerated or surrounded by ice.

    4. Pack it up. At the grocery store, bag fresh fruits and vegetables separately from meat, poultry, and seafood products.

    Bring an ice chest to keep frozen or perishable items if it will take more than an hour to get those items home.

    No ice chest? If it’s hot outside, put the groceries in the air-conditioned passenger area of your car instead of putting them in the trunk, which may not have air-conditioning.

    5. Keep your kitchen clean. Wash your cutting boards, countertops, refrigerator, pots, and utensils regularly in hot, soapy water, especially after they’ve been in contact with raw meat, poultry, and seafood.

    6. Check your cutting boards. They shouldn’t have lots of cracks and crevices where bacteria can lurk.

    7. Sanitize. The FDA recommends periodically sanitizing your cutting boards, countertops, and kitchen sink drain with a homemade mixture of one teaspoon of chlorine bleach to one quart of water.

    Sponges and dishcloths can house bacteria, so wash them weekly in hot water in the washing machine.

    8. Store your food properly. Refrigerate frozen and perishable items as soon as possible.

    Don’t store foods near household chemicals or cleaning products. Some produce — like onions and potatoes — don’t need to go in the refrigerator, but don’t store them under the sink, where they could be damaged by leaky pipes.

    9. Check the refrigerator and freezer temperature. Set the refrigerator temperature to 40 degrees Fahrenheit, set the freezer to zero degrees Fahrenheit.

    Use a refrigerator thermometer to check those temperatures periodically.

    10. Wash your hands. Before you handle food, lather up with soap and hot water, washing your hands for at least 20 seconds. Repeat after handling produce, meat, poultry, seafood, or eggs.

    11. Wash fruits and vegetables in running water. A small scrub brush may help, but don’t use soap or other detergents to wash produce.

    What about produce washes? “All of these solutions and washes may have some applications but studies show that washing with water is as safe as anything else,” says Pillai, who calls water the “most effective, the safest, and the cheapest” way to wash produce.

    12. Thaw foods in the refrigerator, not on the countertop. It may take longer, but it’s safer.

    13. Cook foods thoroughly. Use a meat thermometer to make sure meat is fully cooked. Never put cooked meats on an unwashed plate or platter that has held raw meat.

    14. Store leftovers safely. Refrigerate leftovers in tight containers as soon as possible and use them within three days. When in doubt, throw it out.

    15. Maintain perspective. “There’s no such thing as a zero risk,” says Pillai. ”There’s no such thing as a sterile product.”

    How Yogurt is used in Acne Treatment

    Friday, June 22nd, 2007

    A reader of this blog asked,

    i have pimples and a lot of marks on my face
    i dont know how to get rid of the marks though
    i wanted to make sure if using yoghurt is a good idea

    thanks

    I didn’t actually have the idea that yogurt is used to prevent acne until this question was raised up. Doing my research, I’ve found out that there are actually yogurts especially formulated for acne treatment.

    Here’s what I found out. Yogurt is a great moisturizer and helps soothe red spots and pimples! Yogurt has lactic acid which softens, and tightens the skin and refines the pores. Its high nutrient content and natural antibacterial and antifungal properties also get rid of germs and other bacteria. We know that one of the causes of acne is clogging up of dirt in your pores which serves as friendly environment for bacteria.

    Tips on Handling Childhood Immunization

    Friday, June 22nd, 2007

    Researchers make a series of recommendations about how parents, doctors and nurses can ease the fear and pain surrounding childhood immunizations.

    Before the injection:

    –While details should be guided by each child’s age and development level, researchers found children over the age of 2 benefit when told what will happen and how it will feel. Children can also be asked to help think of things that will help them cope, such as bringing along a favorite toy.

    Researchers suggest the discussions occur as close to the actual injection as possible for toddlers and preschool-aged children to avoid escalating anxiety. For older children, parents need to consider how each child handles stress.

    During the injection:

    –Parents should adopt a calm and matter-of-fact manner, because research indicates adults who are overapologetic, too reassuring, extremely empathetic or critical of their child’s behavior can cause more distress.

    To distract the child, researchers suggested using humor, toys, books, storytelling or deep breathing. For babies under the age of six months, a pacifier dipped in sugar water was recommended.

    For children who are especially anxious, doctors should at least consider using a local anesthetic, researchers said.

    Dengue Cases in the Philippines surged to 6.8% - DOH

    Wednesday, June 20th, 2007

    The Department of Health (DOH) has ordered hospitals to reactivate “Dengue Express Lanes” due to a 6.8 percent upsurge in the number of dengue cases in the country. There have been 7,361 reported dengue cases from January 1 to June 2, 2007, compared to just 6,695 cases during the same period last year. 73 people have already died of dengue in the past five months.

    To make the matter worse, Dr. Eric Tayag, the director of the DOH-National Epidemiology Center, dengue fever has become “hyper endemic” which means it’s already too late for efforts to reduce the number of cases to its previous level.

    This is because all four strains of the dengue causing virus are active and are being spread by the mosquito aedes aegypti at the same time; unlike last year, when only one strain of the virus was being spread.


    Global warming was also said to be one of the culprits of the increase in incidence.

    Warmer temperatures caused by global warming make mosquitoes more hungry for blood and therefore bite people more often in order to feed. Blood makes the mosquito to lay eggs more often thus [there is an] increase in mosquito population. This increased feeding, in turn, completes and perpetuates a deadly cycle: more eggs laid results in more mosquitoes being born, which grow into more carriers of the deadly dengue virus strains.

    Further, with four strains of the dengue virus as potential agents of infection, a person can become ill with dengue as many as four times. This is because a person only gains immunity from one strain of the virus at a time. Moreover, subsequent dengue infections following the first would be more serious for the person getting the disease.

    Prevention

    The DOH advised the public to strictly observe measures in its nationwide anti-dengue campaign. The anti-dengue campaign is now a year-round concern, since dengue cases are now reported during the wet and dry seasons.

    The measures in the anti-dengue campaign include the following four “S-es”:

    Seek and destroy mosquito breeding places. These include all containers that collect stagnant water, like bottle caps, dish racks, cans, empty bottles and used tires.

    Self-protection.
    This includes covering windows and doors in the house with fine-meshed screens, using mosquito nets, and rubbing insect repellent lotions or sprays onto exposed areas of one’s skin.

    Seek medical treatment immediately. High fever lasting 2-7 days, rashes and/or bleeding, severe headache, pain behind the eyes, muscle, joint, or bone pain are some symptoms that could indicate dengue. The DOH advises the public to go to a Dengue Express Lane in a hospital, where proper diagnostic tests for dengue would be administered to a patient.

    Say “no” to indiscriminate fogging. The DOH says that no fogging operations should be done in an area unless there are known dengue cases present.

    New Symptoms for Early Detection of Ovarian Cancer

    Wednesday, June 20th, 2007

    Cancer experts have identified a set of health problems that may be symptoms of ovarian cancer, and they are urging women who have the symptoms for more than a few weeks to see their doctors.

    These symptoms, which are found more common in women, include bloating, pelvic or abdominal pain, difficulty eating or feeling full quickly and feeling a frequent or urgent need to urinate A woman who has any of those problems nearly every day for more than two or three weeks is advised to see a gynecologist, especially if the symptoms are new and quite different from her usual state of health.

    Although these symptoms are acknowledged as classic symptoms or urinary problems of patients with bladder infections it still makes sense to consult a doctor because bladder infections should be treated. Urinary trouble that persists despite treatment is a particular cause for concern, researchers say.
