At Singapore General Hospital’s (SGH) Medical Intensive Care Unit, patients lay quietly in their beds. Many were uncon-scious and were breathing with the help of ventilators. Suddenly, one of them started coughing and gasp-ing for breath. That triggered an alarm and, within seconds, a team of young doctors, nurses and a respiratory thera-pist rushed to his bedside.

They swung into action to maintain his airway, breathing and circulation, monitor his vital signs and initiate emer-gency treatment. One of the medical team members asked: “Hello? Mr James Tan? Can you hear me?”

“I have difficulty breathing,” the patient mumbled.

“What are the latest vital signs?” the medical team leader asked. “BP (blood pressure) is low. Can we prepare to intu-bate the patient? BP is 54/2...”

“Mr Tan, because you’re breathless, we’re going to put a tube into your lungs to help you breathe. Prepare the oral laryngoscope and endotracheal tube.”

Soon, Mr Tan’s condition stabilised and the worst was over.

It was not a real emergency but a simulation of an urgent medical situation which doctors, nurses and other medical professionals have to respond to at any time. And Mr James Tan was actually a life-size doll.

Still, the team showed they had learnt their lessons well by swiftly and confi-dently responding to the “emergency”.

Helping the hospital create the emer-gency situation realistically is a crucial piece of machinery – the sophisticated,

high-tech doll or manikin capable of emu-lating complex medical conditions and responding to treatment.

Although such so-called high-fidelity manikins have been used at SGH’s Insti-tute for Medical Simulation and Educa-tion (IMSE) since 2008, this was the first time one was “called into action” in a hospital ward – with the participants, doctors, nurses and therapist on actual duty, attending to real patients in the intensive care unit.

In comparison to training at the hos-pital’s simulation training centre, “the real life ward setting, the ventilator and other equipment made it easier for us to be immersed in the situation”, said Dr Jona-than Yap, an Internal Medicine Resident.

“The experience was more realistic (compared to that in a simulation lab).”

According to Dr Peter Mack, Senior Consultant, Department of General Sur-gery, and Director, IMSE, SGH, this more realistic approach to training, known as an in-situ simulation, became possible after recent technological advances enabled wireless manikins to be produced. The trainer manipulates the manikin’s “body functions” by controlling signals from a laptop.

“In the ward, participants can check that their equipment and drugs are in order and things are within reach, that they know what to do and where to reach for their equipment. It is a chance for them to find out where the gaps in their processes are and how they work in the real world, and know what can really go wrong,” Dr Mack said.

Simulation in the hospital ward offers valuable opportunities to identify

By manipulating controls on a computer, a trainer can bring on a “heart attack”, “lung collapse” or other medical conditions in the manikin.

With the help of a high-tech lifelike doll, SGH staff train for emergencies in simulated real situations

potential dangers and flaws in the clinical systems, the environment and the acute care team. Having doctors and nurses attend to a wireless manikin like a real patient enhances their learning, corrects their mistakes, fine-tunes their skills and improves team communication. Simu-lated training also allows participants to experience rare clinical scenarios as often as necessary, and helps them keep

up with changing technology, with the ultimate aim of increasing patient safety and delivering quality care.

“In the simulation laboratory, partici-pants often say, ‘We are unfamiliar with this artificial environment, which is why we did things wrongly; but in the ward, we’ll be fine.’ But will they? The only way to find out is to have the situation play out in a real-life setting,” Dr Mack said.

In-situ simulation is a more realistic approach to training, with manikins like this one being used in the wards to emulate medical conditions.

Donation to a public cord blood bank is strongly encouraged by organisations such as the American Medical Associa-tion and the European Group on Ethics in Science and New Technologies. Cord blood from a different person (not the patient’s own cord blood) is most com-monly used for cord blood transplants, as another person’s cord blood will not con-tain the genetic deficiencies that caused the disease, which led to the need for a transplant.

The bank aims to increase its cord blood units from its current inventory of 8,100 to 10,000 by 2014. “If we have between 10,000 and 20,000 cord blood units, we would have a 60 to 80 per cent chance of finding a suitable match for transplantation for the majority of Singa-poreans,” said Dr Hwang.

He added that bone marrow regis-tries around the world have a large pool of Caucasian donors but comparatively fewer Asian donors.

As a result, 65 to 80 per cent of Asian patients in need of bone marrow or blood stem cells for transplant are unable to find a suitable match. This is made worse as patients have only a one-in-four chance of finding a match among siblings.

about 40 to 60 per cent of Singaporeans in need of stem cell transplants cannot find a suitable match,” said Dr Hwang, who is also an Assistant Professor with Duke NUS Graduate Medical School. He thinks the key reason for the low donation rate is the lack of awareness about donations.

“Some mothers may fear donating or choose to keep the cord blood for their own baby or family’s use in the future.”

Doctors in the haematopoietic stem cell transplantation field currently favour public donation, as studies suggest that the chance of using one’s own cord blood is very small and currently does not give better results in treatment.

Wanted: More cord blood donors

In March this year, the Singapore Cord Blood Bank (SCBB) made a land-mark announcement that it had facili-tated its 100th cord blood transplant since its official opening in 2005. The cord blood came from its banked inventory and was donated by an unrelated donor.

It was a major milestone for SCCB. However, the non-profit bank, which is Singapore’s only public cord blood bank, is still looking for more cord blood dona-tions to help other Singaporeans in need of haematopoietic stem cell transplants (blood stem cell transplants).

Drawn from the umbilical cord of a baby after delivery, cord blood is a rich source of self-renewing blood stem cells that can develop into different mature blood cell types, which can save lives after a blood stem cell transplant. Blood stem

cells have proved highly effective in the treatment of blood cancers such as leukae-mia and lymphoma.

The stem cells in cord blood are naive (without prior exposure to any bacteria, virus, parasite or other stimuli) and are unlike bone marrow blood cells. The matching between a cord blood donor and recipient is also less stringent com-pared to the matching requirements for bone marrow cells.

Few mothers donate to SCBB Collecting cord blood presents minimal risk, and is painless and non-invasive, but few mothers in Singapore donate it to SCBB. Of the 35,000 or so births each year, only 10 per cent of mothers donate.

The donation rate could be much better, said Dr William Hwang, Medical Director, SCBB, and Head and Senior Consultant, Department of Haematology, Singapore General Hospital.

As the Singapore Cord Blood Bank celebrates facilitating its 100th cord blood transplant, it is appealing for more donors

BY Jamie ee

Enlarging the poolHe said that, “with cord blood, there is an increased chance of finding a match because it can be partially mismatched to the patient when used for transplants”.

Agreeing, Associate Professor Tan Ah Moy, Head and Senior Consultant, Paediat-ric Subspecialties, KK Women’s and Chil-dren’s Hospital, said: “When you donate cord blood to a common shared resource like the SCBB, more patients are able to access and benefit from it. Although there is a one-in-four chance of a match among siblings, it doesn’t mean every child will find a match among his siblings. In these instances, we still have to search through SCBB for a suitable match.”

To raise awareness here, Dr Hwang and his counterparts have been giving talks to the public and the medical com-munity. Also, to include donors from minority races, SCBB has reached out to organisations like Majlis Ugama Islam Singapura (MUIS) for their endorsement of cord blood donation.

It has had some effect. Mr Steve Sobak, CEO of SCBB, said: “Through various media, obstetricians/gynaecologists, clinic and hospital staff, as well as word of mouth, expectant mothers are coming forward to donate their cord blood. But we need more to increase the chances of patients finding a suitable match.”

Teng Hong Yi (far left, pictured here with his mother Ms Regina Soong and his two siblings) underwent cord blood transplantation two years ago.

Why I donatedWhen her son, Cristan, was born last year, housewife mandy loh, 32, donated his cord blood to sCBB.

“my husband and i decided that we were not going to store the cord blood in a private bank. so rather than discarding it, we thought we should donate it to someone who needs it,” she said.

“it is a good option that mothers should think about because it really brings hope to another person.

“there is so much beauty in bringing a child into this world and mothers can share this joy by giving hope to other people who may be suffering.”

When primary 6 pupil teng hong Yi was nine, he was diagnosed with chronic myelogenous leukaemia, a rare blood cancer. his condition did not improve even after being on medication for a year.

so, his doctor, associate profes-sor tan ah moy, head and senior Consultant, paediatric subspecial-ties, KK Women’s and Children’s hospital, recommended a haemato-poietic stem cell transplant.

his parents and two siblings were tested and tissue-typed, but none were found to be suitable donors. so they turned to sCBB for help. on their second search, they found a

perfect match. his mother ms regina soong, 33, said: “i knew from the doctors and nurses that it was not common to get a match, so i didn’t think we’d be so fortunate to find one and, what’s more, a 100 per cent match.”

two years ago, the Yishun primary pupil underwent cord blood transplantation and, today, the cancer is in remission.

“i will definitely encourage parents to donate their baby’s cord blood because it gives another person a shot at life. if they don’t donate it, it will be discarded and go to waste,” said a thankful ms soong.

g the metabolic rate at rest


News

A sensible, balanced diet, regular exercise and good sleeping habits can give a boost to energy and lead to good health. Other ways of boosting the metabolism include:

Build more muscle mass As muscle burns more calories than

fat, building up more lean muscle will help burn more calories every day. Doing some weight-bearing exercises, such as weight-lifting or walking, will add muscle mass and burn calories.

Avoid skipping meals Significantly decreasing the caloric

intake will slow the metabolic rate as the body enters “fasting” mode and reacts by hoarding fat and burning lean muscle for energy.

Get adequate sleep Not sleeping enough a�ects the

levels of appetite-regulating hormones, and the capacity to metabolise carbohydrates in the body. The metabolic rate nosedives as less fat is burned for energy.

Eat enough protein Protein forms the building blocks

for muscle, and having inadequate protein can lead to the loss of desirable, lean muscle mass.

Drink less alcohol Alcohol slows the fat-burning

process. The body needs to burn calories from alcohol before fat can be lost through diet and exercise.

The SingHealth Guide to Women’s Health,

To measure the resting metabolic rate, a small plastic hood or canopy

is put over the head of the participant who is lying down on a comfortable bed. The canopy measures the amount of oxygen

and carbon dioxide breathed in and out by the participant. This is based on the principle that gases and heat are produced and

used when the body expends energy to power its basic functions while it is at rest. The participant has to remain still and quiet, but

not fall asleep during this test, which takes about half an hour.

People who are interested in taking part in the study can call Miss Stephanie Tan at 6326-6794 or

email her at [email protected] for more information.

Generally, participants have to be healthy, and not pregnant or

experiencing significant weight loss or gain, to participate in the study.

They will need to spend a weekday morning at

SGH Lifestyle Improvement and Fitness Enhancement (LIFE) Centre,

and fast and refrain from smoking as well as moderate to

vigorous activity 10 hours before the test.

By using a small plastic hood, Miss Stephanie Tan (left) is able

rest. She will use the data to develop a formula

The best time to deliver an electric shock to the chest may be during the upstroke of a CPR compression. “Early CPR is important at that point to get some blood flowing,” said Associate Professor Marcus Ong as Ms Samantha Yong looked on.“With the residual oxygen in the blood, the heart is prepared, giving it a greater chance of restarting when a defibrillator is used.”

interviews and counselling at SGH Life-style Improvement and Fitness Enhance-ment (LIFE) Centre. Staffed by a multi-disciplinary team of doctors, dietitians, physiotherapists, psychologists, occupa-tional therapists and medical social work-ers, the centre promotes integrated and holistic care for patients with lifestyle-related medical conditions, such as eating disorders and obesity.

Since his 20s, Mr Lawrence had been seeing Dr Tham Kwang Wei, Consultant, Department of Endocrinology, SGH, and Director, Obesity and Metabolic Unit. It was only late last year that he made up his mind that he was ready for the procedure and the commitment it entailed.

“He was first referred to the Diabetes Centre at SGH as a 19-year-old after he was diagnosed with type 2 diabetes during his national service pre-enlistment screen-ing,” said Dr Tham.

“He was a typical diabetic. He battled with his weight for a long time. He would lose 10kg and bounce back with a 15kg weight gain. He had been seeing us for a good seven years. Then he disappeared off the radar and came back about a year later with very poorly controlled diabetes. His blood pressure was high and his cho-lesterol levels were off the charts. I said, ‘Look, you are young and you can’t go on like that. You are a candidate for a heart attack at 40.’ And that was when we dis-cussed surgery.”

For Ms Rozita, the turning point came a year later when she was in and out of the hospital four times for a host of medi-cal problems which included diabetes, inflamed stomach ulcers, sleep apnoea and an ovarian cyst.

Fed up that her weight was causing her so many problems, she opted for gastric bypass. “I told my husband, ‘I don’t care if you allow me to or not, I am signing the consent form for the surgery.’”

Such determination and commitment is key when assessing patients for bariat-ric surgery, said Dr Shanker Pasupathy, Senior Consultant, General Surgery, and Director, LIFE Centre, SGH.

“There is a common misconception that the operation will fix everything and, after that, you will go on with your life. But that is not true. The surgery is a reset button and, after that, you embark on a new life, not just in terms of eating but your whole approach to life.”

Patients who go to LIFE Centre learn to modify their eating habits. “We talk about eating, selecting food and being relaxed. They need to understand that these are important and they need to make changes. Undergoing surgery to lose weight will help them only 20 to 30 per cent of the way,” Dr Shanker said.

Bariatric procedures – whether it is a gastric bypass, gastric lap band surgery or gastric sleeve surgery – are doomed to fail if patients do not make dietary and lifestyle changes, he added. They could regain all the weight they worked so hard to lose in the first place.

Post-surgeryAfter surgery, a patient’s stomach is reduced to the size of a tiny pouch that is attached to the middle portion of the small intestine. Eat more than what the pouch can handle and the patient will throw up. Mr Lawrence typically eats a slice of bread for breakfast, a small piece of fish for lunch and a small piece of chicken for dinner. “Less carbohydrates, no fried chicken, which I loved, and no rice. I no longer remember what rice tastes like.”

Ms Rozita, who admitted she used to not know the word “full” when it came to food, has taught herself to say “no” to a lot of it.

She and Mr Lawrence are now commit-ted to a life of careful eating, exercise, a regimen of daily supplements and regu-lar visits to LIFE Centre to monitor their progress. They have become advocates of a healthy lifestyle as family members and friends follow their new habits. Mr Law-rence’s family alone has collectively lost over 30kg since his surgery.

“That one person who has had surgery and has been taught about eating becomes a nucleus of change for the family,” Dr Shanker said.

Patients are helped by the support of others in the same boat. Prospective patients and people going through the various post-operative phases attend sup-port group meetings at LIFE Centre, held every other Wednesday evening.

Why collagen is important?In the composition of cartilage we fi nd 67% of collagen versus 1% of glucosamine.Glucosamine is an aminosaccharide contrary to collagen which is a molecularcomplex containing amino acids. Glucosamine is found in interesting quantities only in the liquid of the synovial membrane. Collagen is also found in the synovialmembrane but in larger quantities because the protein structure is more abundant inthe body.

Glucosamine acts more like a lubricantin the joints while collagen helps the tendons, ligaments, cartilage, muscles, membranes and synovial liquid (lubrifi -cation).

Our tendons... Our body’s rubber bandsBy observing the diagram of the human body on this page, we can easily recognize all the space that our muscles, ligaments and tendons occupy. The tendon is composed of thick, white fi bres of collagen that are held tightly against one another. These fi bres are made up in large part by collagen.

Our ligaments act like a connection between the bones. Our tendons act like ties to our internal structure for our muscles and our bones. The tendons and the ligaments of our body act like rubber bands of different sizes.

Since our tendons are used to bind our musculature to our bones, and to maintain elasticity and suppleness, our tendons necessitate a large amount of collagen, particularly after an injury or from aging.

Water (for moisture)

Oils (for lubrication)

Mucus (for even spreading)

Antibodies and special proteins (for resistance to infection)

Special glands located around the eyes secrete these components. An imbalance of these can cause dry eyes.

was using them every half an hour, especially when I had to work on my computer for a long period. After a while, I started getting a gritty feel-ing in my eyes. On some days, my eyes became so inflamed, I had to rush to the emergency department,” said the 55-year-old procurement manager in the telecommunications industry.

When she was approached to be part of a study to try new eye drops made of her own plasma, Mrs Ng was more than willing to give it a go.

Commercial products are not able to completely replicate the tears we produce, which contain many proteins. Research-ers from the Singapore Eye Research Institute (SERI) and Singapore National Eye Centre (SNEC) believe that the clos-est substitute is plasma – the yellowish fluid in blood that carries all the different blood cells.

These are definitely encouraging results. When we recently announced the findings at an international meeting, the audience was equally enthusiastic.dr LOUIS TONG, CONSULTANT, SINGAPOrE NATIONAL EYE CENTrE, ANd LEAd INVESTIGATOr OF THE PLASMA EYE drOPS STUdY

Mr Hoesny also tried several over-the-counter eye drops and eye gels, but found relief only when he joined the study and started using the plasma eye drops.

Patients in the study undergo a pain-less one-hour procedure, similar to a blood donation, to extract the plasma from their blood. The plasma is then placed in narrow tubes clamped about an inch apart.

Stored in the freezer Patients store these tubes in the freezer and break off the required segments for their daily use. Some, like Mr Hoesny, even double-bag them before keeping them in the freezer to ensure they do not get contaminated. Although patients have to ensure the segment they are using remains in a cool environment throughout the day, neither Mrs Ng nor Mr Hoesny considers it a chore.

“I don’t think it’s an inconvenience at all. In fact, it is worth the trouble because it really improved my dry eyes,” said Mrs Ng, who stores her eye drops in a baby

food container, which is then kept in an insulated bag.

Researchers optimisticThe improved comfort experienced by patients is backed by observations of the study team.

“We observed reduced damage on the epithelial cells (cells at the surface of the eye) after six weeks of treatment. These are definitely encouraging results. When we recently announced the findings at an international meeting, the audience was equally enthusiastic,” revealed Dr Tong.

The team is optimistic that treatment based on this principle may, in future, become the gold standard in dry eye treatment for challenging cases. In the meantime, the team will continue with an observational study for one to two years to look at the long-term effects of the treatment.

Future availabilityThe plasma eye drops will be manufac-tured at the Blood Services Group (BSG) of

Health Sciences Authority of Singapore, which will also aid in storing them for the individual patient.

“As the freezing facility at BSG is reli-able and more spacious, patients can have half their stock of plasma eye drops stored there. When they run out of their supply about five or six months later, they can collect the other portion without having to undergo another plasma extraction process,” explained Dr Tong.

For patients like Mr Hoesny, it is good news indeed. “The plasma eye drops are purely from our plasma, so they are very safe and effective. I was lucky to be part of the study. Although I will now need to pay for them as the study period is over, it will still be a lot cheaper than buying over-the-counter eye drops which are not completely effective,” he said.

“While its composition is not perfectly identical to tears, plasma contains many proteins that are present in tears. The proteins provide a normal, anti-inflam-matory environment for the eye surface and, therefore, plasma could well be a tear substitute,” said Dr Louis Tong, Con-sultant, SNEC, and lead investigator of the study.

Oh, what a relief!Dry eye, a common condition that affects the quality of life of its sufferers, is caused by multiple factors such as ageing, trauma to the eye or certain disease con-ditions. It may also be a side effect of cer-tain drugs or treatment. For example, Mr Hartono Hoesny, 61, developed dry eyes after undergoing a bone marrow trans-plant for cancer.

“I had the transplant about 10 years ago. After that, I developed various reac-tions that affected my mouth, skin and nails. But my eyes bothered me the most because it felt like there was sand in them,” said the supervisor of a food dis-tribution company.

From the letters to the press, it apparently matters whether the doctor is a foreigner or Singaporean. People are concerned if the foreign doctor is attuned to the local culture and lan-guage, and whether he is as competent as his local counterpart.

For instance, the patient may get frustrated if the healthcare professional isn’t able to understand why he is reluc-tant to undergo surgery. There may be issues specific to the local context that the foreign doctor may not understand

I tried to register on behalf of my elderly and immobile parents at the polyclinic, but was advised by the counter sta� that my parents have to be present during registration. I understand the need to verify a patient’s identity, but I feel that verification is more important during consultation than at registra-tion. Also, only the patient’s name has to be verified, so why do patients need to be present at registration?

Lunch is servedimagine having to cook several meals a day for over 1,000 patients with different dietary needs. that’s the job of sgh Food services Department. We take a peek inside its kitchen as it whips up lunch

8am: Breakfast is over, get ready for lunchThe cooks and kitchen helpers, num-bering 31 at any one time, work two shifts – from 6am to 7.30pm – with a small group in as early as 5am to pre-pare breakfast. The main kitchen closes at around 7.30pm, but a satellite kitchen in the main hospital block stays open for another hour. At the wards, biscuits and milk drinks are available for patients who get hungry between meals or late at night. A variety of meals cater to different tastes, and dietary and reli-gious requirements.

Spices and seasoning for each dish are

carefully measured and prepared

according to the recipe and the

number of orders.

Rice porridge is cooked in huge vats and is served plain or used to make pork or halal chicken congee.

For patients on a low-sodium diet,

no soya sauce is added to the little

saucers of cut chilli.

10.15am-12pm: Roll out the trolleysThe cooks dish the food onto plates according to order chits attached to each tray. The orders indicate the patients’ preferences and dietary restrictions. The order chits for halal meals are printed on green paper. The Food Services staff check the orders before they print the chits, and also before the meal trays are loaded into the trolleys bound for the wards.

The trolleys have a cold compartment to keep fruits and desserts fresh and separate from a compart-ment preheated to 75ºC.

A last check is made before the trolleys are locked and sent to the wards. There, the food is reheated for 20 minutes so patients are served a hot meal.

To make sure orders are served

correctly, food order chits for

each patient are printed, and

arranged by ward and bed numbers.

Left: After cook-ing, kitchen staff dish the meat and rice onto plates and soup into bowls placed on trays, reading off the individual order chits attached to each tray.

Below: At every meal, samples of food that is cooked and served to patients are taken. This is a safety precaution to allow the hospital to quickly track down the source of contamination in the event of food poisoning. SGH is ISO 22000, including HACCP, compliant. This means it ensures food safety – through approved safeguards in areas with the potential for contamination.

Right: Chicken is roasted in trays for a Western meal. Pork, a Chinese mainstay,

is also available. Fish is served as

A jab in timeProtecting your child against hepatitis is not as hard as you think. By Thava Rani

Beware of cockles and needles

Protect your child

The disease is essentially an inflammation of the liver, which may be due to a viral infection or exposure to toxic substances, alcohol or certain medication. Although hepatitis A, B and C are similar in nature, the virus that causes each disease is di�erent.

Older Experience more children severe symptoms,

with more than 70 per cent developing jaundice

It was during the euphoric years after World War II that Western industrialised nations (with the notable exception of the US) first established the foundations of the modern welfare state.

Based on an egalitarian vision of society, one of its tenets was that citizens would enjoy universal access to health-care, funded either by taxes (as it was in Britain, Canada and Sweden) or state-mandated social insurance schemes (the practice in France, Germany and the Netherlands).

Unfortunately, the euphoria did not last long. Well before the recent global financial crisis, healthcare costs in many developed countries were already spi-ralling out of control, fuelled by ageing populations, rising patient demand and escalating costs associated with advances in medical technology. What was once “affordable” grew into a crushing burden.

Healthcare comes at a costHealthcare does not come free. Someone must pay. But who and how? And having settled that question politically, what if healthcare costs grow (they inexorably will, as new treatments and more effective drugs come on stream) into a bottomless pit? There are no easy answers, which is why no country appears to be completely happy with its healthcare system, with many in the midst of reform (and some even moving in contradictory directions with each change of government).

Much of the current debate on health-care reform revolves around the key issue of sustainability. Apart from rationing and queuing, various governments have in recent years sought to achieve this by diversifying funding sources, encour-aging greater individual responsibility through co-payments and turning to the free market in order to deliver healthcare services more efficiently.

It is in this light that the concept of national health insurance and its rel-evance to Singapore, as extolled by advo-cates, such as Dr Jeremy Lim (The Moral Case for Health Insurance for All; The Straits Times, April 26, 2012), ought to be examined.

National health insurance entails a state-mandated, risk-pooling system into which all must pay, and from which all will benefit, so the burden on any one individual is ameliorated.

The idea of universal health coverage is a noble one. But it does not automati-cally lead to better healthcare at afford-able costs. On the contrary, countries with such healthcare systems invariably strug-gle with cost containment, since increased

Singapore’s multilayered healthcare financing system has enabled it to achieve the same goal of universal access to healthcare, while keeping services afford-able and ensuring the system remains sus-tainable in the long term. Over the years, it has purchased for Singaporeans good health outcomes, comparable and often superior to those of other developed coun-tries, at a much lower cost. The country’s total health spending is at four per cent of its gross domestic product (GDP), com-pared with countries of the Organisation for Economic Cooperation and Develop-ment, which spent an average of 9.6 per cent of their GDP on healthcare. In the case of Taiwan, the figure is 6.6 per cent.

The system is not perfect, but it has served Singaporeans well for the last 28 years. Rather than totally redesigning it, what is required is to continue building on its strengths while addressing existing gaps (such as tackling coverage for costly, non-catastrophic illnesses). Greater efforts should also be made to balance efficiency with compassion (for example, showing more flexibility in the implementation of the safety net so no one falls through the cracks).

And yes, the next phase of the evolution of the healthcare system should continue to be shaped by the national conversation regarding the kind of society Singapore wants to be. But make no mistake – despite claims to the con-trary, there is no “magic bullet”.

access must necessarily mean increased utilisation of healthcare services, not to mention the greater potential for abuse, fraud and wastage.

Indeed, a close examination of health-care systems worldwide suggests that there has to be a more nuanced and mul-tidimensional approach to healthcare financing, and that a one-size-fits-all approach would, at best, be a partial solu-tion. The current trend towards hybrid and structurally complex healthcare sys-tems seems to bear this out.

While the idea of universal health coverage is noble, there is no one-size-fits-all solution that balances citizens’ needs with rising healthcare costs

JUL⁄ aUG 2012 SinGaPOre HeaLTH 19

Singapore’s multilayered healthcare financing system has enabled it to achieve the same goal of universal access to healthcare, while keeping services affordable and ensuring the system remains sustainable in the long term.

government expenditure account for only 57 per cent of total health expenditure at the national level, with individuals forking out a significant proportion out of pocket.

Furthermore, because of high con-sumption and the inability (politically) to raise premiums to cover rising costs, the scheme was plunged into financial difficulties just a few years after it was introduced in 1995. Since then, NHI’s defi-cit ballooned further – to NT$60 billion (S$2.6 billion) in 2009.

Singapore’s system worksIn contrast to Taiwan, Singapore’s health-care financing system consists of multiple channels of financial support. The 3M system – Medisave, MediShield and Medi-fund – treats the majority of healthcare consumers as co-paying partners, while making special provisions for the minor-ity who cannot afford the co-payment.

Aside from 3M, Singaporeans have access to government subsidies at public hospitals. Thus, the basic medical needs of all Singaporeans, including the minority without insurance cover, are taken care of. In addition, the government periodi-cally pays money (from budget surpluses) into the savings schemes of low-income families and the elderly.

Such an approach not only counters the “moral hazard” generally associated with free-for-service, third-party reim-bursement (Singaporeans know this as the “buffet syndrome”), but also avoids providing the rich with healthcare handouts (as would be the case under a universal coverage system that ignores income status).

Consider Taiwan’s National Health Insurance (NHI). It is a mandatory, single-player health insurance scheme that covers the entire population, with con-tributions from households, employers and the government. While the coverage is meant to be extensive, NHI and other

Most of us have probably seen advertisements – like those hanging from bus and MRT hand-rails, plastered on lightboxes and websites or printed in news-papers – recruiting healthy indi-viduals for clinical research. I never really paid attention to them. I was never going to take part in a clinical trial.

I was wrong.During my student days, my friends

took part in trials out of curiosity or to earn a bit of extra cash. At the time, I was never in such a need of money to consider this income opportunity and definitely not curious enough.

In 2006, the UK was shaken by the “elephant man disaster” at Northwick Park Hospital. Six healthy young men took part in a study of a targeted cancer therapy, which was being tested for the first time in humans. Within hours of get-ting the drug, they were all in intensive care with something close to multi-organ failure. They swelled up so much that the local media dubbed them the “elephant men”. None have fully recovered. I was glad that I’d never been foolish enough to risk my life like that.

Then, I joined the healthcare indus-try. Suddenly, I was reading about clini-cal trials all the time. I was talking to patients whose disease had been stabi-lised by a trial drug when everything else had failed. There were also stories of patients who did well for a while before the disease caught up with them again. But they all had one thing in common –

Becoming a guinea pig for the greater goodHealthy volunteers who take part in clinical trials accept the potential risks in the hope that taking part will benefit patients in future

they took part because they hoped that, if this didn’t work for them, it would benefit patients in future.

I was also talking to doctors who were trying to raise awareness of ongoing trials to attract more healthy volunteers. Unlike patient volunteers, who suffer from illnesses that cannot be treated or for whom current treatment options no longer work, healthy volunteers don’t stand to gain any personal health bene-fits. The researchers said it is often harder to recruit healthy subjects.

As memories of the “elephant men” faded, and feeling safe in the knowledge that only a few studies allowed young women to take part, I enthusiastically vol-unteered myself to one of the researchers. Little did I expect her to tell me that they were about to start a trial that required both men and women.

Half hoping that she would forget my pledge, I didn’t think much about it again. But she did remember. Still, I wasn’t really

worried about taking part in a clinical trial because I had the right to change my mind about participating at any point – even after signing on. But the least I could do was find out more about the study.

So I found myself listening to the prin-cipal investigator of the study explain the trial details – how it was going to work, what kind of study it was and what was required of me.

This procedure is now standard for any clinical trial involving healthy and patient volunteers. But, as recently as the last century, doctors saved patients’ lives by taking chances with treatments that were not fully understood or tested. In 1937, Professor ES Monteiro decided to give a patient, who had been admitted to the old Singapore General Hospital with cardiac beri beri, a dose of vitamin B1. A deficiency of vitamin B1 was suspected – but not yet proven – to be the cause of beri beri. Within half an hour of getting the treatment, the patient sat up in bed, confounding the nurse’s expectations; she had already laid out a sheet in anticipation of the patient’s death. Prof Monteiro used the treatment on other patients after that, achieving a 100 per cent success rate.

There are also instances where such lack of control and protocol led to the exploitation of research subjects. The infamous Tuskegee syphilis study is prob-ably the best-known example. In this study, about 400 poor African-Americans with syphilis were recruited for a study on “bad blood” – a term used to describe various ailments including syphilis. They never got the treatment they needed (even after penicillin became available) because the scientists wanted to observe how the disease developed. All the participants died. In 1997, President Bill Clinton apolo-gised for this atrocity.

Since then, safeguards have been put in place. I was benefiting from the prin-ciple of informed consent that has been

enshrined in research ethics since the end of World War II. Throughout the explanation by the principal investigator, I felt pretty comfortable with the idea of taking part in the study. Nothing much was required of me, the only down side was that the study included a followup period of several years.

But when the principal investigator got to the side effects, which included very rare instances of a possibly fatal con-dition, my heart stopped. He said that the chance of this happening was very small, but he could obviously not guarantee that it wouldn’t happen. Gulp.

Was I ready to risk my health, and pos-sibly my life, to help test this new drug? Or could I become an “elephant woman”?

If I developed this rare side effect, I’d regret it forever. But then I realised that if all the other potential volunteers felt like I did at that particular moment, and if eve-ryone walked away, then this drug – good or bad – would never be available. Even the incident in the UK didn’t stop people from supporting clinical research, and count-less treatments have since been launched, including a vaccine against cervical cancer and a treatment for Hepatitis C. There will always be some risk. Even taking a fully licensed medicine involves risks. It is just that you know what the risks are.

I am a firm believer in modern medi-cine. If this drug proved effective, then yet another potentially fatal disease (one that I could very easily get) could be thwarted. Surely that was worth taking a small risk for?

A postscriptThese days, most serious studies have multiple “arms”, which are like teams. Participants in each arm either get the test drug or a placebo. When I signed up for the study, neither the doctor nor I knew which arm I was in. It was only sev-eral years after the first consultation that I finally found out. It turned out that I had received the placebo. I felt disappointed. Somehow, my contribution seemed less meaningful than it would have been had I been given the trial drug.

A silicone eye is hardly something you would expect to see on a visit to the National Dental Centre Sin-gapore (NDCS). But then again, Dr Teoh Khim Hean is not your average dentist.

Artificial eyes, ears, jaws and other facial prosthetics are tools of his trade. Senior Consultant and Director, Department of Restorative Dentistry, NDCS, Dr Teoh, whose work is in prosth-odontics, is also a specialist in maxillo-facial prosthetics.

The only such specialist in NDCS and one of a handful in Singapore, Dr Teoh was trained in maxillofacial prosthetics at the prestigious Memorial Sloan-Kettering Cancer Center in New York.

Patients at NDCS who see him for prosthetics generally have facial defects brought on by horrific accidents or after they have had cancer surgery. With his knowledge of medicine and dentistry, he crafts prosthetics that “plug” gaps in the face and jaws.

The work calls for artistic flair, as the artificial parts have to blend seamlessly with facial features and skin tones. Inter-estingly, he counts portrait photography as a hobby.

The artist in the dentistAmong a rare breed, Dr Teoh Khim Hean’s work requires medical expertise, a kind heart and a touch of artistry

can do more for these patients, and it’s so rewarding when you see them doing well, or having some normality handed back to them,” he said.

This dentist with a big heart has more that he wants to do. He hopes that NDCS will one day be home to a regional train-ing centre for maxillofacial prosthetics, as such expertise is needed in Asian Third World countries, which tend to have a high incidence of oral cancers.

Currently, he is engaged in training others in the subspecialty at NDCS. He said that to succeed in this field, entrants need two qualities: passion and perseverance.

“The demanding circumstances we work in call for perseverance to see cases through from start to finish. And pas-sion drives us to pursue better outcomes for our patients, to see them healed and whole again.”

The prosthetics are not permanently attached to the face but can be taken out and cleaned every day. They minimise the disfigurement and offer patients hope and confidence to face the world again.

Many patients who see him are emo-tionally devastated, desperate, and dis-traught by their illness and ravaged appearance. He often finds himself having to counsel as well as treat them.

the prosthesis. He recounted how an elderly cancer patient, in this situation, chose not to seek further medical care.

“She felt that she had gone through so much in the previous six to eight months. She told me: ‘I’ve lived enough. I’ve seen enough, I don’t want to continue.’” The scene was so distressing that Dr Teoh’s nurse could hardly hold back her tears.

Emotionally draining but rewardingDr Teoh confessed that the work can take a toll on emotions, which is probably why, he said, not many people are inclined towards maxillofacial prosthetics.

He unwinds by spending time with friends or colleagues, and occasionally taking vacations. However, despite the emotional challenges he faces, he is moti-vated to soldier on.

Supporting medical researchAs a clinical research coordinator, Ms Liew Yee Yun helps doctors with their research studies at the National Heart Centre Singapore

My job is to… Help principal investigators conduct their research studies. I approach patients, explain the study to them and if they agree, recruit them for the study.

Careful planning, precise coordina-tion, meticulous data collection and dili-gent pouring through of case notes are all part and parcel of my job.

I work very closely with doctors, nurses and technicians. Currently, I’m working on two studies with another potentially in the pipeline.

In the seven months I’ve been here…I have become better at approaching people and understanding doctors’ hand-writing. I’m also grateful for the help I have received from my colleagues.

What most people don’t know about me is that… I can be really stern. Because I look soft and innocent, people, especially my

colleagues, don’t expect me to be aggres-sive. However, I don’t think you can accom-plish much at work if you’re stern.

The one thing I’ll never forget is… The day a patient, whom I had been follow-ing up on, died. I had spoken to him a few days earlier to confirm our appointment.

But when he did not show up, I called

Bahru. It helps me relax since I’m so far away from work.

On special occasions like Mother’s Day, my siblings and I will cook a special meal for our parents.

I am… An introvert. Previously, I worked as a lab technician where there was no need for me to interact with people and I was quite happy with that.

But after four years, I realised I needed a change. I decided to challenge myself with a job like this so I could improve my communication skills.

I think research is… A very important aspect in the practice of medicine. Although we may not see results immediately, in the long run, it helps to improve patient care.

It’s a much-needed part of medicine because it pushes us to be better and not settle for the current status quo.

I smile the most when I am… Listening to patients’ experiences and life stories. Whether they end up participating in the study or not, they all appreciate the sharing session.

Within the next five years… I would like to take more courses to improve my skills at work.

A Cardi� University study has shown that a brain-training

technique that helps people control activity in a specific part

of the brain could help treat depression. Researchers at the

university used MRI scanners to show eight participants how their brains reacted to positive

imagery. After four sessions, their depression improved significantly.

But there was no improvement in eight others who were asked to think positively, but did not

see images as they did so. The scientists said further research with more people is needed to test the technique’s long-term

研究破除大肠手术谬论

他们都得在新加坡中央医院康跃中心通过一连串的严格面试和咨询。由多学科专业医疗人士组成，包括医生、营养医师、心理治疗师、心理学家、职能治疗师和医学社会工作者，康跃中心是专为患有与生活方式相关病症，例如患有饮食障碍和肥胖症的病人提供综合式全面护理的治疗中心。

自20多岁开始，Lawrence先生已经是谭光慧医生的病人了。谭医生是新加坡中央医院内分泌科的顾问医生兼肥胖及代谢组的主任。直到去年下半年，Lawrence先生才下定决心接受手术。

谭医生说：“当时他在全国征兵预检时被诊断患有2型糖尿病，随后被转诊到新加坡中央医院糖尿病中心时才19岁。”

“他是个典型糖尿病患者，长久以来与他的体重交战。他的体重可以减少10公斤，随后又反弹增多15公斤。他来我这里就诊前后有7年多然后消失了一年，再次找我时是因为他已难以控制糖尿病病况。他的血压高，胆固醇水平也远远超过正常范围。我对他说，‘你还年轻，不能这样下去，否则你在40岁时就已经患有心脏病。’就在这时候我们才开始谈论手术。”

Rozita女士患有多种疾病，包括糖尿病、炎症性胃溃疡、睡眠呼吸暂停症及卵巢囊肿。她在一年之内前后住院4次。正因如此让她改变了想法。

减肥手术使两名病患成功抵抗糖尿病、肥胖症及其他并发症

现年32岁的Shuan Lawrence先生和36岁的Rozita Ramlee女士的体重曾经超过100公斤。

如今遇到他们时，您无法想象他们曾经患有肥胖症。为了治疗肥胖症、糖尿病及其他并发症，两人不约而同地在新加坡中央医院接受胃旁路手术。这是一种减肥手术，对逆转糖尿病和其他代谢性疾病都有非常好的疗效。

“过去，我不能行走远程，不能搭乘公共巴士，也不敢乘坐捷运。这手术让我重获新生，”Lawrence先生说。现在定期跑步的他也开始游泳和健身。“活了30多年，我现在可以对食物说‘不’了”。

在手术前，Lawrence先生的体重是117公斤，身高体重指数（BMI）为35。去年11月动手术后，如今他的体重是85公斤。

Rozita女士在手术前是属于“超级肥胖”型，BMI为50，体重高达128公斤。于去年9月做了减肥手术后，她现在的体重已减至93公斤。

目前，两人都无需再服用治疗糖尿病、高血压和高胆固醇的药物，也不用继续接受睡眠呼吸暂停症的治疗。

巨大的改善 Lawrence先生的空腹血糖指数也曾在前两年飚升至15.5mmol/L，但最近的一次血液检测发现血糖已经降至5.7mmol/L的健康水平。去年Rozita女士每三个月测量的血糖水平（也称为糖化血红蛋白或HbA1c）高达8.6%。手术后的6个月，也降至5.7%的良好水平。可见已停止服用降血糖药的两人，新血糖水平也有着卓越的改善。

Lawrence先生曾经鼾声如雷，甚至会吵醒邻居，如今他晚上睡觉时再也不打鼾了。而Rozita女士曾经患有阻塞性睡眠呼吸暂停症。这种病症使患者在深度睡眠时由于气道闭塞而会周期性地停止呼吸，因此不得不使用连续气道正压通气（continuous positive airway pressure，简称CPAP）装置帮助睡眠。现在，她再也不需要它也能睡得安稳。

不过，接受胃旁路手术的过程并非一帆风顺。

王银花女士竭力寻找能治疗干眼症的方法有近三年了。她每眨眼一次就会感到眼睛表面层好像被刀削掉一样。甚至有时，疼痛剧烈到半夜都会被痛醒。于是，她将自己的血液制成润眼液缓解症状。

王女士说：“用血浆制成的润眼液对缓解干眼症真的很有效。因为它是用我自己的蛋白质制成的，所以能缓解眼部干涩，不会刺激到眼睛。”

王女士的干眼症是因治疗视网膜疾病时而进行多次手术后所引起的。除了使用非处方的润眼液缓解症状外，她还尽量避免到有冷气的地方，甚至在卧室内也安装了加湿器，为的就是避免让眼睛干涩。尽管如此，频繁使用润眼液却带来其他问题。

现年55岁的王女士是电信行业采购经理，她说：“直接从药房购买的润眼液只能暂时缓解我的症状，所以我几乎是每半小时就得滴一次，尤其是在我长时间使用电脑时。过了一阵子，我开始感觉眼里好象有沙子。有时，我的眼睛会变得红肿且发炎，以致必须赶紧去急诊室求诊。”

所以当她受邀参与一项使用自己的血浆制成新型润眼液的研究时，王女士是非常乐意参加的。血浆是呈黄色的液体在血液中运载所有不同种类血细胞。

因为人们体内所产生的泪水中涵盖多种蛋白质，所以市售上的润眼液不能完全复制泪水。新加坡眼科研究所和新加坡全国眼科中心的研究人员相信最接近泪水的替代物是血浆。

新加坡全国眼科中心角膜及眼表疾病科顾问医生童学天说：“虽然血浆成份与泪水并不完全相同，但是血浆含有泪水中所有的多种蛋白质。蛋白质为眼表面营造了一个正常、抗炎的环境，因此血浆可以是很好的泪水代替物。”童医生也是这项研究的第一负责人。

对肥胖问题而患上的疾病厌烦不堪，她便要求做胃旁路手术。“我告诉我丈夫说，不管你是否同意我做手术，我都要在手术知情同意书上签字。” 据新加坡中央医院康跃中心主任兼普外科高级顾问医生Shanker Pasupathy所说，

这样的决心和意志对评估病人是否适合减肥手术至关重要。

“许多人认为减肥手术可以解决所有问题，手术后就可以随心所欲。其实，事实并非如此。手术就象个‘复位’按钮，可以让你展开新生活，不仅仅是饮食上，而是面对整个生活方式的态度，”他说。

在康跃中心，病人学习如何改变饮食习惯。“我们讨论饮食、食物选择以及放松心情。他们需要了解这些事项的重要性以便作出调整。减肥手术只能帮助他们减轻 20%至30%的体重。”

要是病人不调整饮食和生活方式，任何的减肥手术，不管是胃旁路手术、腹腔镜下胃束带术或胃囊袋切除术都将注定要失败 Shanker 医生补充道。这样辛辛苦苦削掉的体重也会因调整不当而复胖。

手术后Lawrence先生和Rozita女士异口同声地表示他们手术后的复健过程也不是件易事。

轻松多了！干眼症是一种能影响患者生活质量常见的疾病。造成干眼症的因素包括老化、眼睛创伤或某些疾病，也可能是由于某些药物或治疗的副作用。例如，61岁的Hartono Hoesny先生就是因患有癌症而在骨髓移植后而患上了干眼症。

这位食品配送公司的主管说：“我在10年前做了骨髓移植后出现了各种排斥反应影响了口腔、皮肤和指甲。但是，给我带来最大困扰的还是眼睛，因为总感觉眼睛里有沙粒。”

囊，与小肠中段直接相连。如果进食量超过小囊的容量，病人就会呕吐。

Lawrence先生早餐通常吃一片面包，午餐吃一小块鱼，晚餐吃一小块鸡肉。“我只吃少量的碳水化合物，不能吃我爱吃的炸鸡，也不能吃米饭。”

Rozita女士断言，对于食物她从来不曾有过‘吃饱了’的感觉，不过她已经学会克制自己，对很多食物说‘不’了。

现在他们两人终身都得坚守严谨的饮食习惯、锻炼和每日营养补充品的摄入，并且定期到康跃中心监测自己的进展情况。他们也当起健康生活方式的大使，因为他们的家人和朋友都以他们为榜样，从而为自己选择健康的生活方式。自从Lawrence先生接受手术后，其家人的总体重也削了超过 30公斤！

Shanker医生说：“关键不在于手术，而是了解如何进食和如何面对生活。这样一来，手术后还学会如何正确饮食的人就会成为改变其家庭成员的饮食习惯的核心人物。”

拥有同样经历的病人之间也会互相扶持。在康跃中心，每隔周三傍晚都会举行支援小组聚会，让将要接受手术的人和已接受代谢手术或经历了各种术后阶段的人参与。

为什么眼睛会变得干燥？眼睛表面持续由具湿润作用的泪水保护着。眼泪的成份是：

水份以保持湿润油脂以保持润滑粘液以保持均匀涂布抗体和特殊蛋白质以抗感染

眼睛周围的特殊腺体会分泌这些成份。这些成份的失衡则会引起干眼症。

如何知道眼干当泪水无法有效润滑眼睛，你就会感到：

疼痛畏光沙粒感眼睛含沙粒的感觉眼睛发痒眼睛发红视力模糊

血浆。之后将血浆装入相间隔离约一英寸的细管中。

存放在冰箱中患者将这些细管存放在冰箱中，然后依日常所需把部分细管折断使用。有些患者如Hoesny先生，甚至用双层袋子包装细管才放入冰箱，以确保细管不受污染。虽然王女士和Hoesny先生都必须确保他们使用的部分血浆整天都处于阴凉的环境中，但是他们都不嫌它麻烦。

王女士说：“我根本不觉得有任何的不方便。事实上，那样大费周章还是值得的，因为我的干眼症真的得到了改善。”王女士将她的润眼液存放在一个婴儿食物容器中，然后再放入一个保温袋里。

研究小组很乐观地认为，未来以这原理为基础的疗法将会成为较难治疗的干眼症病例的“黄金标准”。与此同时，小组必须继续进行一至两年的研究，以观察它的长期疗效。

血浆润眼液将由新加坡卫生科学局血液服务处生产，该部门也会帮助患者储存其血浆润眼液。

“由于血液服务处的冷藏设施更为可靠、也更为宽敞，患者可以将其一半的血浆润眼液存放在那里。当患者用完存放在家中的血浆润眼液后，他们可以从血液服务处拿取其余的存货，而不必再

产出不少相当不错也具有一定的抗皱效果的产品。

那些产品也含有功效特强处方产品当中找得到的少量成份，例如，用于黄褐斑（也被称为妊娠斑）的淡化色素美白霜来对抗脸上的褐色斑点。正因如此，零售产品的副作用相比之下虽然比较低，但却没有显著的效果。

“然而，美容产品公司常常将其特殊成份大肆吹嘘为下个大热门，例如，声称干细胞能够改变肌肤基因。理论上听起来是很不错，但实际上却缺乏科学根据。”

维他命A疗法王医生唯一知晓的科学研究是广泛地用于美容

产品上的维生素A衍生物。她说：“从减缓肌肤中的胶原蛋白和弹性组织退化显示，它们是具有一定的延缓肌肤衰老迹象的功效。”

“类维生素A （Retinoid，维生素A局部衍生剂）有经过医学研究证实有一定的可信度，研究结果曾被刊登在医学期刊上。A 酸（Retin-A ）是处方药物不能在外购得，但较为温和的维生素A乳霜可轻易在零售商店买得到。”

抗皱乳霜中的其他活性成份都是抗氧化剂，这包括维生素C和E、谷胱甘肽和天然有机酸（果酸），例如甘醇酸和乳酸。抗氧化剂是被认为能够减缓肌肤细胞损伤，果酸则是能够祛除死皮令肌肤更具有光泽的成份。

保持白皙除了维生素A以外，美白产品通常也含有维生素C、天然有机酸、甘草以及曲酸（一种源自蘑菇的天然亮肤成份）。

许多女性都会尝试任何能保证青春源泉的产品。但樟宜综合医院皮肤科顾问医生王逸诗却提醒大家不要对那些瓶瓶罐罐有过高的期望。

王医生表示：“抗皱产品能够延缓衰老迹象，但却不能预防皱纹产生或消除皱纹。这方面只有整形手术才能做到。”她补充说，皱纹，例如笑纹和鱼

王医生表示：“虽然零售产品能够淡化最常见的色素沉淀问题，但往往都不能完全清除它。”

“通常，避免日晒是女性达到白皙肌肤的方法。对那些希望保持肌肤白皙的女性，我建议使用防晒霜，避免日晒并在晚上涂抹维生素A乳霜。”

她说：“防晒还能降低患皮肤癌的风险以及预防早期幼纹。”王医生也建议那些喜欢水上运动或长时间在阳光下的人们，使用至少30防晒系数的防晒霜。由于有效性会逐渐消退，所以必须在每两至三个小时重新再涂抹一次。

但另一方面，持久防晒的皮肤会缺乏充足阳光照射。她说：“在这种情况下，就得到诊所监督你的维生素D的水平，如有必要，可服用补充剂。”

对肌肤有一定功效的维生素A衍生物可在许多美容产品中找得到。

王逸诗医生表示：“我对那些希望保持肌肤白皙的女性建议使用防晒霜，避免日晒并在晚上涂抹维生素A乳霜。”

肤更新还能减缓皱纹和细纹的出现。这种乳霜会令你的肌肤对阳光照射更加敏感，所以不能在白天使用，也不能暴露于阳光底下。我每周两到三次还会使用果酸乳液来祛除死皮。”

新加坡中央医院的一项研究发现，与传统的开放式手术相比，大肠腹腔镜或微创手术并不会带来更高的术后并发症风险，这是高龄患者的福音。

研究显示，如果患者健康状态适合接受手术，就应该让微创手术列为选项之一。微创手术是通过微小的切口，借助微型摄像放大手术部位并呈现于屏幕上以进行手术。

新加坡中央医院结肠直肠科副顾问医生陈华锈说：“我们发现手术不受年龄限制。研究发现接受腹腔镜手术的患者恢复得更快，住院时间更短，而且疼痛程度也较轻。”

陈医生表示这项研究的目的在于证明大肠癌年长患者进行腹腔镜手术后不会有更高术后并发症风险，年长患者应该可从这项手术中获益。研究人员也尝试更深的了解高龄患者在长时间的麻醉下是否会出现更多的并发症。这是由于技术较为复杂，所以微创手术的时间会比传统手术稍长。

陈医生说：“我们的数据显示接受微创手术的高龄患者术后并发症的发生率并不比接受开放式手术的患者高。”

肉、豆类以及乳制品的膳食有助于满足这些基本需求。液体也是保持良好的水化作用的必需品。营养丰富的膳食对获得足够卡路里是非常重要的。以复合碳水化合物为其中主粮，可以修复细胞的蛋白质、脂溶性和水溶性的维他命以及矿物质都有利于总体健康。

我们的身体会随着年龄的增长而经历一场生理和代谢的变化。新陈代谢使我们体内迅速转换能量来运作各种功能，它的波动对基本营养成分的吸收有一定的影响。

除了一般必需的维他命和矿物质外，老年人还需要更多特定的营养成分，如钙和维他命D。

陈医生补充说，一般来说，根据复杂程度相比，传统开放式手术的时间为

半小时到稍微过4小时之久，而微创手术则需要1到6小时。

她说：“但我们发现高龄患者并不受此影响。与麻醉有关的并发症主要会出现在手术后。微创手术的并发症风险或许来得更高，但我们发现实际情况并非如此。微创手术的并发症发生率是相似的，而不是更高。”

我的女儿两岁又两个月大，睡觉时打鼾已经有一段时间了。她一度经常感冒，医生说这是打鼾的主因。即使她的感冒复原后，打鼾问题仍然存在。有时候，她看似一面睡、一面打鼾。有时候，又像是因打鼾而有呼吸困难。请问我们应该怎么办?如果您发现女儿有时似乎有“呼吸困难”，那就应该向家庭医生或儿科医生咨询。她有可能患上阻塞性睡眠呼吸暂停，是会导致睡眠时上呼吸道出现间歇性障碍。

您的家庭医生或儿科医生将能检查孩子的鼻喉，确定是否有过敏性鼻炎的症状、扁桃腺肿大以及其他能导致阻塞性睡眠呼吸暂停的因素。医生会根据打鼾的原因让你的孩子通过口服或鼻腔，用药物治疗过敏性鼻炎，或者转介到儿科睡眠专家作进一步检查。

新加坡中央医院答复：我们拥有病人的病历，但是为了避免可能出现的疏忽或失误，譬如遣派错误的医疗文件或与病人到手术室的医疗记录不完整，所以我们的工作人员必须在病房和手术室各个地方核对病人的姓名、身份证号码、手术型式以及病人本身允许手术等信息。

积极参与并有效的沟通是防范失误的重要因素，病人也在确保自身安全方面扮演着重要的角色。在进行手术前，手术团队成员会做最后的核，确实他们是在为正确的病人和正确的部位实施正确的手术。

实际的预测一份保险可能无法报销所有的医药费。了解自付额和共保额，以免收到医药费账单时大吃一惊。

46岁的亚莫先生买了一份附加险，以使自己的医疗保险更加全面。附加险的保险义务如下：

每日住院医疗补助：每日住院他都将获得一定金额的现金补贴

重大疾病医疗补助：如果确诊患有条款约定里的30种重大疾病之一，他将获得一次性全额支付的重大疾病保险金

涵盖自付额和/或共保额：帮他支付全部自付额和/或共保额，这是受某一极限限制的

自付额是投保人根据保单条款自付的一次性为期一年的费用。共保额是需投保人在支付自付额后自己承担付出医疗费用的部分，通常是支付自付额后赔付金额的一个固定比例。

后来，亚莫患病需要实施手术。他以为自己的医疗保险会报销全额医药费，所以未核查保单、也未与保险公司确认其他约定的条款便确定了手术日期。出院后，他把所有医药费账单拿到保险公司进行报销。

没想到自己迎来的却是当头棒喝。保险公司拒绝报销全额医药费，因为亚莫的附加险项只涵盖共保额，而没有涵盖自付额。他必须自行承担自付额部分。

此外，每份保单每年都需支付自付额和共保额。由于亚莫部分住院费的支

付时间属于新的保险年度，所以这些账单需要根据个别年度的自付额和共保额另行报销。

保险条款亚莫的案例说明，了解自付额和共保额以及它们是否适用承保范围内的所有报销费用非常重要。

医疗保险的保单中通常有自付额和共保额的规定。由投保人自己承担部分医药费不但能够避免医疗保健机构过度消费，也使投保人能够担负得起保险费。

下表是对自付额为3,000元、共保额为10%的例证：

医药费 $ 13,000自付额 $ 3,000净额 $ 10,000共保额 $ 1,000保险公司赔付金额 $ 9,000

每份保单中不同类型的保险都有自己的赔付限额。如果开支超出这一限额，投保人就需自己支付其余的费用。在上述示例中，医疗费账单应在保单的赔付限额之内。

投保人需了解保险公司能够赔付多少医药费，这一点至关重要，因为各医疗保险保单都有限定的赔付限额。保单可能对所有情况的赔付都已规定了最高限额，包括年度或终身疾病以及伤残的赔付限额。

投保人可享用两份或多份保单的赔付，但同时拥有多份医疗保险保单

未必能为投保人带来额外的利益给付，因为总数的利益

给付受限于投保人的实际医疗

开销。

医疗费用保险(或住院和手术保险)

健康保险计划的种类健康保险计划涵盖的范围

支付有关事故或疾病的医疗费用。支付范围通常包括：• 住院治疗/手术• 某些门诊手术• 住院前和出院后的专家

咨询• X光• 实验室测试

“重大”医疗费用保险通常赔付由重大疾病(例如，心脏搭桥或器官移植)造成较长期住院开支

注意事项

不论投保人拥有多少份保单，报销的费用涵盖投保人应付的实际费用(自付额较低)。因此，购买额外的医疗费用保单未必能为投保人带来额外的利益给付

保单均有对自付额和/或共保额的条款约定，自付额和/或共保额在投保人要求赔付之前就规定了投保人应自行支付的最低限额

对于投保人的赔付要求，每份保单都有最高赔付额度。保单可能对所有情况的赔付都已规定了最高限额，包括年度或终身疾病以及伤残的赔付限额。为获得更高的利益给付，投保人可综合两份或多份保单的赔付限额

可能不予报销某些疾病的医疗费，例如既存病历

可能需要一直等到发生意外伤害时才能获得医疗费的赔付

保险费率可能得不到保证

医疗保险的保单中通常有自付额和共保额的规定。由投保人自己承担部分医药费不但能够避免医疗保健机构过度消费，也使投保人能够担负得起保
