Stem Cells

Dear Readers,

Today let's take the opportunity to discuss the very elusive and less understood topic amongst many - stem cells. An overview of their origin, behaviour and most importantly functions. 

Just imagine the stem cell as the mother of all cells - the one who nurtures and teaches the other cells, transforming them into adult cells with specific roles and responsibilities within the human body. Like in all hierarchy, there is one that also exists in this stem cell world. Some stem cells have greater capacity to differentiate and direct tissue systems, where as other stem cells may only have limited power and life span. It makes sense that stem cells would be more effective when obtained from an actively growing life source, whereby their degree of differentiation and maturity would be unrivalled. 

They serve as an internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Stem cells are capable of replication, proliferation, differentiation and long term cell renewal.

Broadly stem cells are categorised as Embryonic and Non Embryonic (adult). Embryonic stem cells are derived from the embryo, as the name implies. These cells are very versatile and can differentiate into any cell type. Adult stem cells on the other hand, are not from the embryo, but instead from specific tissue systems like blood, muscle, skin etc. They can only differentiate into their own lineage and kind. The word "potency" describes the degree of differentiation capable of a stem cell.

The extensive research on stem cells and its capacity to replenish itself has brought about a profound eye opening in the medical world. Most research is on adult stem cells, as studying human embryonic cells is deemed unethical - and rightfully so too.

Just to add on, a popular subtype of adult stem cells are Mesenchymal Stem Cells. Mesenchymal stem cells (MSCs) are adult stem cells traditionally found in the bone marrow. They can also be isolated from other tissues including cord blood, peripheral blood, fallopian tube, and fetal liver and lung. Multipotent stem cells, MSCs differentiate to form adipocytes, cartilage, bone, tendons, muscle, and skin. Mesenchymal stem cells are a distinct entity to the mesenchyme, embryonic connective tissue which is derived from the mesoderm and differentiates to form hematopoietic stem cells.

So in conclusion, we have this great repair system whose consumables consist of our very own blood, fat and skin. Really makes life a whole lot easier when one needs a new kidney.

In actual fact however, stem cell research has pioneered numerous success stories. Stem cells are being used to treat a variety of disorders like Parkinsons, myocardial ischaemia, congenital disorders and many more. In years to come, we should be able to regenerate faulty organs within the body and restore balance and homeostasis.

The Miracle Hormone - Melatonin

Dear Friends & Readers,

Today, let's talk about the king of the hormones - melatonin. I am assuming that many of you may not have heard about this silent giant, who works stealthily at night.

Melatonin is a natural hormone primarily made by the pea sized pineal gland located in the mid-brain. It is also produced in the gut and retina. During the day the pineal is inactive. When the sun goes down and darkness occurs, the pineal is "turned on"  and begins to actively produce melatonin, which is released into the blood. Usually, this occurs around 9 pm. As a result, melatonin levels in the blood rise sharply and you begin to feel less alert. Sleep becomes more inviting. Melatonin levels in the blood stay elevated for about 12 hours - all through the night - before the light of a new day when they fall back to low daytime levels by about 9 am. Daytime levels of melatonin are barely detectable. 

Just a nutshell about sleep itself. Definitely an interesting physiology in my opinion. Still baffles me as to how God figures out things to such intricate of details. 

Sleep starts of with non-REM (rapid eye movement) phase - during this phase the body repairs and regrows tissues, builds bone and muscle, and strengthens the immune system. REM sleep happens 90 minutes after you fall asleep. The first period of REM typically lasts 10 minutes. Each of your later REM stages gets longer, and the final one may last up

to an hour. Your heart rate and breathing quickens. You can have intense dreams during REM sleep, since your brain is more active.

So where does melatonin  fit in in all this? Basically this wonder hormone keep the sleep wake & light cycle in check. If not for melatonin, humans may be running about like bunnies on Redbull, not being able to cease the body's activities. This in turn would result in defective healing and restoration of cells and organs. Simply put, we would be ageing at the speed of lightning.

People with sleep disorders generally have irregular melatonin levels. Melatonin release is inhibited by light - whether it is sunlight or even the blue light from your iPhone. So imagine the chaos in a shift workers hormone cascade. Take for a example, a nurse on night duty at the hospital - she is busy taking care of her patients and serving drugs - her pineal gland is going to be confused as to whether it should release melatonin or not. The last thing we want is a nurse doing CPR going into non-REM sleep!! Similarly, the same chaos occurs on long distance flights - the result jet lag. Besides being affected by occupational reasons, immuno-suppressed individuals may also be combating irregular melatonin levels due to compromised nutrition and depleted hormones. On the contrary, your friend whose always yawning at work is probably producing too much melatonin in the daytime - causing him to feel sleepy and less alert.
                                     

 Melatonin also functions as a potent antioxidant in our bodies. Amongst its numerous functions are:

a) free radical scavenger

b) stimulates anti-oxidative enzymes

c) lowers free radical generation

d) augments efficiency of other antioxidants

e) Protects against molecular damage

Melatonin and its metabolites are potent antioxidants with anti-inflammatory, hypotensive, cell communication enhancing, cancer fighting, brown fat-activating, and blood-lipid-lowering effects, thereby protecting tissues from a variety of insults. Melatonin has been shown to support circadian rhythm, hormone balance, reproductive health, cognition, mood, blood sugar regulation, and bone metabolism, while improving overall antioxidant status and lowering blood pressure. Melatonin may assist in preventing diabetic complications, and improving treatment outcomes in patients with cardiovascular disease and certain types of cancer.

For those of you against taking supplements, here's a list of melatonin boosting foods - pineapples, papaya, oranges, sweet corn, oats, rice, barley, bananas & tomatoes.

Now for those who are supplement addicts, please add this miracle hormone into your routine. Melatonin can be taken as a pill or sublingually. It has a short half and only stays active in the system for about 20 minutes. Ideally it is taken about 30 - 60 minutes before sleep. Do not be exposed to bright lights and activity before taking melatonin, as this would negate the effects of the supplement. Please also be warned that melatonin interacts with other drugs like oral contraceptive pills and anti-epileptics - so do consult your doctor before starting your melatonin journey!!

Mediterranean Diet & Longevity

Dear Readers,

A warm welcome, following a restful weekend I hope. Today's topic will definitely delight the Malaysian individual.










The Mediterranean diet was originally inspired by the traditional dietary patterns of Greece, Southern Italy and Spain.  This diet includes proportionally high consumption of olive oil, legumes, unrefined cereals, fruits, and vegetables, moderate to high consumption of fish, moderate consumption of dairy products like cheese and yogurt, moderate wine consumption, and low consumption of meat and meat products.

A new study hints that eating the much acclaimed Mediterranean diet may help boost longevity. Researchers found that the mediterranean regimen appears to be associated with longer telomere length, which are indicators of slower aging.

Continue reading below...

Telomeres are located on the ends of chromosomes -- much like the plastic tips on the end of shoelaces. According to geneticists, telomeres prevent chromosomes from fraying and scrambling the genetic codes they contain. These bits of genetic material naturally shorten with age, but they tend to shorten more slowly in healthy people.Shorter telomeres have long been associated with a greater risk of age-related diseases and a shorter life span, experts say. Shorter telomeres are also associated with obesity, cigarette smoking and high sugar consumption.

red portions - telomere

Why does the Mediterranean diet work? One theory is that this diet significantly reduces saturated fat consumption and eliminates trans fat intake, thereby reducing atherosclerosis and significantly improving cardiovascular health. Another is that it reduces inflammation. Still another is that it supplies significant quantities of free radical-fighting antioxidants. Perhaps all these factors play a role. Key components of the Mediterranean diet have been shown to be anti-inflammatory. Among these are omega-3 fatty acids from fish.

Greek researchers documented improvements in insulin sensitivity, as well as decreases in cholesterol levels and systolic blood pressure, even among overweight and obese men and women who at least came “close” to sticking to the Mediterranean diet. This implies that this diet is also protective against type 2 diabetes and combats obesity.


So step up and look out for some olive oil today!

Testosterone Replacement Therapy

Testosterone is the primary male sex hormone that is vital to keep in check man's primal and carnal desire. It is also critically involved in building lean muscle, burning fat, and supporting blood function, energy level & mood, immune function, and bone density. By the 7th decade, a man’s testosterone level may only be 20% of what it was in his youth. This slow and steady decline in testosterone can start as early as the mid-30s, and can result in an increased risk of life-threatening illnesses such as obesity, diabetes, and heart disease. This event is termed andropause, the male equivalent of female menopause.

 

Like men, one issue with testosterone that complicates matters is the fact that it exists in several different forms in the blood, and each form has a different hormonal activity. “Free” or unbound testosterone is a fully active hormone, but protein-bound testosterone are only partly active, or sometimes completely inactive. What is usually measured in a blood draw is the total testosterone, which is a combination of the free and protein-bound forms.
 

The good news is that many symptoms of testosterone deficiency can be reversed by restoring youthful testosterone levels in a variety of ways. Millions of men are now using testosterone-building supplements and even testosterone itself for this reason.

 

In a nutshell:

1. Testosterone, the chief male hormone, is essential for libido and erectile function, and plays a crucial role in mood, energy, bone health, and body composition.
2. Testosterone levels decline with age, usually beginning in a man’s mid-30s. Diminishing testosterone levels have been linked with disorders such as depression, fatigue, obesity, and cognitive decline.
3. Low testosterone levels increase the risk of coronary heart disease as well as cardiac mortality.
4. Restoring testosterone to youthful levels offers men a wealth of health benefits, including benefits for heart health, body composition, mood, and memory.
5. Bioidentical testosterone has not been found to have adverse effects on the healthy prostate gland—in fact, it may help improve prostate symptoms in men with low-normal testosterone levels.

Regular blood testing can help you and your physician decide if testosterone therapy is right for you.

 

Optimizing testosterone levels requires a multi-pronged approach that includes optimal diet, proper nutrition, nutritional supplements, exercise, and bioidentical testosterone, if necessary. Optimizing testosterone levels in men requires a multi-faceted approach that includes proper lifestyle, nutrition, nutritional supplements (such as lignan and plant extracts), dietary modifications, and exercise, as well as testosterone supplementation and other prescriptive approaches when indicated.

 

Initially, a medical history and physical examination should be performed, along with a blood-testing panel that includes not only testosterone levels, but also other important parameters such as fasting glucose, PSA, estradiol, and complete blood counts. 

 

Careful, thoughtful optimization of testosterone levels with a comprehensive evaluation and treatment plan can result in dramatic improvements in one’s overall health and well-being.

 

For men who no longer produce enough testosterone,  a topical  cream can be applied to restore testosterone to youthful ranges. These testosterone creams usually come in delivery systems that enable the precise amount of this hormone to be applied to the skin each day for absorption into the bloodstream.

 

The reason testosterone cream is used as opposed to tablets is that the oral ingestion of testosterone can result in rapid degradation in the liver and wildly inconsistent blood levels. A testosterone cream, on the other hand, gradually releases into the bloodstream, which is more analogous to the way testosterone is naturally secreted each day by the testicles of younger men.

 

Follow-up blood testing 30-60 days later is important to ensure that PSA, estradiol, and other blood markers stay in normal ranges. Some men will aromatize (or convert) testosterone into estrogen, which necessitates the use of aromatase inhibitor drugs or nutrient-lifestyle changes to inhibit excess aromatase activity.

 

It’s important to know that if you’ve had prostate cancer or breast cancer you are absolutely not a candidate for testosterone therapy.  Testosterone can make either of these cancers grow faster. 

 

It would only be fair to also mention the side effects of testosterone replacement therapy in this article:

 

• fluid retention - during first few months of initiating therapy
• liver toxicity - with oral testosterone
• problems with fertility - which is why therapy is more important for men who have completed their families.
•  worsening of sleep apnoea
• enlargement of breasts
• increased red blood cell production
• prostate abnormalities
• altered cholesterol balance

Chemical Peel

 

Hello and welcome readers,

 

Today I am going to highlight a fairly common skin treatment - chemical peeling. A novel procedure practiced since the days of Cleopatra and the pharaohs of Egypt.

 

A chemical peel, also called chemo-exfoliation or derma peeling, is one of the least invasive ways to improve the appearance of your skin.

 

Cleopatra was famous for her beautiful skin. Her secret was that she soaked in baths of fresh milk.

Modern laboratories now know why milk worked such wonders for her skin: the lactic acid in milk is an alpha-hydroxyl acid, a natural material that dissolves the glue that holds dead skin cells together. Milk can cleanse the skin down to its deepest layers.

 

A chemical peel can help improve:     

• Acne or acne scars - by regenerating new skin from chemical micro trauma
• Age and liver spots - destroying melanocytes and pigment clusters
• Fine lines and wrinkles - improving skin's collagen and elastin
• Freckles - removes epidermal pigments
• Irregular skin pigmentation - evens out melanocytes
• Rough skin and scaly patches - by chemical exfoliation
• Scars - promotes cell regeneration
• Sun-damaged skin - enhances skin immunity and macrophage clearance of toxins

Chemical peels are broadly defined by the depth of damage in the skin that they produce. They are categorized as superficial, medium, and deep. Superficial peels do not damage skin below the epidermis, the most superficial skin layer. Medium peels may reach to the superficial layer of the dermis, the deeper layer of the skin. Deep peels generally reach the deeper layers of the dermis. The depth of damage depends on the nature and concentration of the chemicals in the peeling solution and the length of time they are permitted to interact with the skin.

 

Generally, fair-skinned and light-haired patients are better candidates for chemical peels. If you have darker skin, you may also have good results, depending upon the type of problem being treated. But you also may be more likely to have an uneven skin tone after the procedure.

 

The skin is thoroughly cleansed to remove all oil, contaminants and sebum. Following this, one or more chemical solutions such as glycolic acid, trichloroacetic acid, salicylic acid, lactic acid, mandelic acid, jessners acid with or without added ingredients like vitamin C or kojic acid is applied uniformly on to the skin using a cotton tip or brush. The applied acid penetrates into the skin, the depth depending on the strength of the acid. This results in a controlled micro-traumatised milieu, which in turn provokes cell turnover and rejuvenation. The stronger the acid, the deeper the peel.

 

Depending upon the type of chemical peel, a reaction similar to sunburn occurs following the procedure. Peeling usually involves redness followed by scaling that ends within three to seven days. Mild peels may be repeated at one to four-week intervals until you get the look you're after. Medium-depth and deep peeling may result in swelling as well as blisters that may break, crust, turn brown, and peel off over a period of seven to 14 days. Medium-depth peels may be repeated in six to 12 months, if necessary. During a chemical peel, most people feel a burning sensation that lasts about five to ten minutes, followed by a stinging sensation. Putting cool compresses on the skin may ease that stinging. You may need pain medication during or after a deeper peel.

 

 

 

 

The skin is especially sensitive after a chemical peel. It is essential to practice strict sun avoidance during and after the healing process. The skin may remain sun sensitive for some time after a moderately strong peel.

 

The risks, side effects, and complications of chemical peels include scarring, infection, reactivation of herpes simplex infections, and a substantial contrast in coloration of the treated skin. All patients will have a recuperation period, the length of which depends upon the depth of the peel. Deep peels can result in substantial periods of healing on the order of weeks.

 

I would like to conclude by adding that I had my own salicylic & lactic acid peel done three days ago, and just loving the brighter and smoother complexion.

 

Will keep you posted on my next choice of treatment!

Beckers Naevus

Hi guys, please don't get stumped by the slightly confusing title.

Beckers Naevus is neither a name nor a brand. Ironically, this pretty name defines a relatively common skin pigmentation amongst mankind.


I figured a skin topic would rock the boat a little, especially that I had one such patient at the clinic today.

Becker naevus's is a superficial birthmark occurring mostly in males.  It is due to an overgrowth of the epidermis, pigment cells and hair follicles. It develops during childhood or adolescence on the shoulders or upper trunk, occasionally elsewhere. It is thought that it is due to a gene defect, which has not yet been identified. It may be triggered to develop by circulating androgens (male hormones such as testosterone), which is why it appears in males at puberty.

 

Usually a Becker’s naevus is too large to be surgically removed. Different laser systems have been used to treat both the colour and the hair. Overall the excess hair responds better to laser treatment than the colour.

If there is acne or eczema within the Becker’s naevus, treatment of these skin conditions can be helpful.

Unfortunately, there is currently no cure for a Becker’s naevus. It will not go away on its own.

For such pigmented naevi, birthmarks and sun spots the Q-switched Alexandrite and Q-switched Nd:YAG lasers are ideal treatment tools. The Q-switched lasers target darkly pigmented tissue, whether this is due to melanin or dye, and leaves lighter tissues unaffected.  The result is to fade pigment in the treated area, and even if an area requires multiple treatments for full effect, each treatment will show significant improvement.

A Nourishing Morning Routine

What makes up your mornings? A violent attack at the snooze button? Droopy eyes checking watsapp messages on the phone? Skipping breakfast because you had to dry your hair? Is your body shouting out to you to slow down the pace? Do you even stop for a second to listen to what the mind is saying?

                                                                               

Maybe you do, but are unsure of what else is possible. Getting out of that comfort zone isn't easy. It's always tempting to sleep for "just a few more minutes." Even if the night were an hour longer, we would still try to get an extra five minutes of shut-eye. Its only our limitation as a human.

Below are five ideas that can help you create a habit that nourishes your mind, body and soul:

1. Eat a few pre-soaked almonds.

Make it a habit to soak six to eight almonds every night. Peel the almond skin and eat them first thing in the morning. You can soak other dry fruits, too, based on your preferences.

2. Say at least one affirmation.

When you look in the mirror while washing your face or brushing your teeth, spare one minute to tell yourself that it's a good day and you're thankful for that. See how good that smile looks on your face! Tell yourself that one task which you are going to finish today. Willpower is highest in the morning, so start strong.

 

3. Start drinking green tea with lemon.

Put the green tea bag in warm water. Add honey and squeeze some lemon. It's a wonder herb. Sit in fresh air, savour every sip of it. Hear the birds tweeting; observe the green trees; play with your pet; see the rising sun; be grateful for the morning; be present in the moment.

 

4. Go on a mindful walk, no matter how long it is.  

Choose a green and clean place. Take deep breaths. Focus on the rhythms of breath. Observe the blue sky, the trees and then the ground. Repeat. Go from slow, to brisk, and back to a slow pace. From increasing your blood circulation to releasing your muscular tension, from making you calm to opening up your chakras, walking daily is a must.

 

5. Try a few yoga poses.

 

It's not just breathing in and out. It's connecting your inner self to nature. That's how life energy sustains. It nourishes your body, mind and soul; everyone needs that.

 

Cheerful, calm, composed, nutritious and grounded mornings will make your whole day fruitful. We can always use a lack of time as an excuse. Try doing it for a week. Notice the difference in your days. You won't want to quit the routine after feeling its effects.

 

Get your mornings in check today.

Skin Anti-Oxidants

Firstly, a brief mention on anti-oxidants and its function. Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Antioxidants are found in many foods, including fruits and vegetables. They are also available as dietary supplements. Here are a few of the most effective ones:

Vitamins C, E and Selenium

Research has found that vitamins C and E, as well as selenium, can help protect the skin against sun damage and skin cancer. And they may actually reverse some of the discoloration and wrinkles associated with aging. These antioxidants work by speeding up the skin's natural repair systems and by directly inhibiting further damage,

Coenzyme Q10

Coenzyme Q10 is a natural antioxidant in the body that helps the cells grow and protects them from the ravages of cancer. A drop in natural levels of coenzyme Q10 that occurs in our later years is thought to contribute to aging skin. A study published found that applying coenzyme Q10 to the skin helped minimize the appearance of wrinkles.

Alpha-Lipoic Acid

This antioxidant, when applied topically as a cream, may help protect the skin from sun damage. Studies have looked at creams with 3%-5% concentration, applied every other day and building up slowly to once daily, and found some improvement in sun-induced changes in the skin. 

Retinoic Acid

Retinoic acid is the active form of vitamin A in the skin and the "gold standard" in anti-aging skin care. according to Burke. Topical retinoic acid treats fine wrinkles, age spots, and rough skin caused by sun exposure.  Researchers have found that treatment with retinoic acid restored the elastic fibers that keep skin taut, and reduced the appearance of wrinkles.

Flavonoids (Green Tea and & Chocolate)

Green tea and yes, even chocolate, just might help improve your skin. Research suggests that the flavonoids in green tea are strong antioxidants that may help protect the skin from cancer and inflammation.

B Vitamins

The B vitamins are essential for cells throughout the body, including skin cells. It's important to get enough of foods rich in B vitamins, such as chicken, eggs, and fortified grain products, because a B vitamin deficiency can lead to dry, itchy skin. Vitamin B6 protects against sun-induced skin damage and decreases wrinkles.

Other Antioxidants

Many other plant-based extracts are being studied for their positive effects on the skin, either when ingested or applied topically. Examples are rosemary, tomato paste (lycopene), grape seed extract, pomegranate, and soy. Some experts feel that a blend of many different antioxidants and extracts might be more effective than individual products. The final answer about the best doses and extracts remains to be determined by researchers.

Ageing

Hi guys,

 

Hope everyone's had a great weekend and a moderately decent Monday. Today's topic is of universal precedence, and often lurks in the minds of many. Some may be concerned by premature lines, whilst others are preoccupied with diminished energy or poor memory.

 

Ageing has indeed become an adjective. The common man often believes ageing is inevitable and that it is part and parcel of fate. But has anyone ever wondered, what are the intricacies that has transpired within the body - eliciting this controlled and premeditated event called ageing.

 

There are two main groups of aging theories. The first group states that aging is natural and programmed into the body, while the second group of aging theories say that aging is a result of damage which is accumulated over time. In the end, aging is a complex interaction of genetics, chemistry, physiology and behavior.


 

 

The Theories:

 

1. Programmed theories assert that the human body is designed to age and there is a certain biological timeline that our bodies follow.
2. Programmed Longevity: Aging is caused by certain genes switching on and off over time.
3. Endocrine Theory: Changes in hormones control aging.
4. Immunological Theory: The immune system is programmed to decline over time, leaving people more susceptible to diseases.
5. Error Theories: assert that aging is caused by environmental damage to our body's systems, which accumulates over time.
6. Wear and Tear: Cells and tissues simply wear out.
7. Rates of Living: The faster an organism uses oxygen, the shorter it lives.
8. Cross Linking:: Cross-linked proteins accumulate and slow down body processes.
9. Free Radicals: Free radicals cause damage to cells that eventually impairs function.
10. Somatic DNA Damage: Genetic mutations cause cells to malfunction.

Studies have demonstrated that genetics can play a major role in aging. When researchers adjust the genes in certain mice, yeast cells and other organisms, they can almost double the lifespan of these creatures. The meaning of these experiments for people is not known, but researchers think that genetics account for up to 35 percent of the variation in aging among people.

 

As we age, our body's organs and other systems make changes. These changes alter our susceptibility to various diseases. Researchers are just beginning to understand the processes that cause changes over time in our body systems. Understanding these processes is important because many of the effects of aging are first noticed in our body systems. Here is a brief overview of how some body systems age:

• Heart Aging: The heart muscle thickens with age as a response to the thickening of the arteries. This thicker heart has a lower maximum pumping rate.
• Immune System Aging: T cells take longer to replenish in older people and their ability to function declines.
• Arteries and Aging: Arteries usually to stiffen with age, making it more difficult for the heart to pump blood through them.
• Lung Aging: The maximum capacity of the lungs may decrease as much as 40 percent between ages 20 and 70.
• Brain Aging: As the brain ages, some of the connections between neurons seem to be reduced or less efficient. This is not yet well understood.
• Kidney Aging: The kidneys become less efficient at cleaning waste from the body.
• Bladder Aging: The total capacity of the bladder declines and tissues may atrophy, causing incontinence.
• Body Fat and Aging: Body fat increases until middle age and then weight typically begins to decrease. The body fat also moves deeper in the body as we age.
• Muscle Aging: Muscle tone declines about 22 percent by age 70, though exercise can slow this decline.
• Bone Aging: Starting at age 35, our bones begin to lose density. Walking, running and resistance training can slow this process.
• Sight and Aging: Starting in the 40s, difficulty seeing close detail may begin.
• Hearing and Aging: As people age, the ability to hear high frequencies declines.

 

 

So what is it we mere mortals can do to combat this dance with mother nature?

Fungal Infection of Nails

Today's topic highlights a common ailment that affects our nails - fungal infection, medically termed as Onychomycosis. Often confused with Athletes Foot - which is fungal infection of the skin on the feet, especially between the toes. In athlete’s foot the responsible fungus lives in the keratin that makes up the outer layer of the skin. When the fungus spreads to the keratin of the nails, the result is a fungal nail infection. The common invader are Dermatophytes, but other species like Candida and Microsporum can also be implicated.  Toe nails are more commonly affected (80%) as compared to finger nails, and that too usually the big toe and the little toe nails respectively.

Onychomycosis & Ingrown Toe Nail 

Destruction of nail plate

This infection usually seeks those with a compromised immune system like the elderly or Diabetic. Certain strains multiply and extend their spores and mycelia through damaged portions of the nail apparatus. So all of you with ingrown nails pinching the corners of the nail's edge - beware!!

 

When fungi infect a nail, they usually start at its free edge, and then spread down the side of the nail towards the base of the cuticle. Eventually the whole nail may be involved. The infected areas turn white or yellowish, and become thickened and crumbly. Less commonly there may be white areas on the nail surface.  Sometimes, especially in those who carry out regular wet work such as bar staff or cleaners, the skin around the nail becomes red and swollen. Called paronychia, this can allow infection to get to the nail.

Onychomycosis can be confused with several other conditions like nail psoriasis, old trauma and even a resolving infection. Confirmation is by taking a section of the crumbly nail or debri beneath the nail edge, and performing a smear or culture. Results may take up to 2 weeks.


Fungal infections of the nail do not clear up by themselves, but not all of them need treatment. Some people with infected toenails are not bothered by them at all. In that case they can sometimes be left alone (although the patient should remain cautious and try not to spread the infection to other parts of the body and nails or other people). On the other hand, if infected nails are embarrassing or uncomfortable then they are usually treated. It is important to treat people whose infections may cause significant health problems such as those with diabetes or immune suppression, in order to prevent potentially severe health problems

The aim of the treatment is to get rid of the fungus: the nail will then usually return to normal. However, if the nail was abnormal before it was infected, it will be harder to clear and may just go back to its former state. Nail infections caused by moulds and yeasts can be very resistant to treatment.

Treatments include topical and oral medications. Surgery is rarely practised. Topical medications generally are poorly absorbed by the nail plate and bed, and such may prove to be a frustrating option. Oral medications on the other hand are effective, but require to be taken for several months and also have a lesser safety profile. Recent advances in treatment include using lasers or photodynamic therapy.

The long pulsed Nd.Yag laser is one of the ideal lasers used to treat Onychomycosis. The laser  energy evenly heats throughout the depth of the effected nail and skin tissue, effectively weakening and killing parasitic fungi which have infected the patient's nails. A completely clear nail plate is achieved in 93.5% of patients according to a British study.

Till the next article.

regards,
Dr Aarthi Maria

Greetings

Dear All,

 

It has been a fantastic journey thus far.

 

The road to health and happiness used to be one less travelled. Fortunately enough, there has been a recent paradigm shift within this realm of thought, with particular reference to Malaysians. Our second nature, calling for extra sugar and tambah nasi - has begun to see its end. People are moving towards greek yoghurt smoothies and a No Carb lifestyle, and judiciously at the gym despite the thirteenth hour. Is this a reciprocal of true value to health, or yet another commercial gimmick that plagues our ignorance? Only our future obesity rate will set the record straight.

 

Having said that, I would like to welcome you to this blog. I hope that it would prove to be both informative yet a fascinating read. It should strike a cord, challenging the reader to aspire for more knowledge with regards general well being, longevity, nutrition, skin and medical aesthetics. The word anti-aging, was coined for a reason after all.

 

Please don't mistake this page for an attempt at commercial gratification, instead I hope it would instead be regarded, as a place to go to when seeking a trustable source.

 

Its best I describe myself, before I jump into the trustable source bit - a true Sagittarian by nature, I love medicine and its numerous tributaries. Nothing gets me as bewitched as when I am; with an interesting article on say for example - the Okinawan people. I have spent much time, money & years acquiring knowledge from various sources, organisations and countries - and believe I have finally reached the stage of being called an expert in my areas of interest.

 

I only hope I can share what has been provided to me so generously.

 

Regards,

 

Dr Aarthi Maria
