Bold Wish
are bursting to green
the soft glow of sunshine
starts warming to spring
That cold winter past
Just sad memories
with jumbled new life
exploding new trees
as seasons progress
so do our souls
hardened cold hearts
to rekindled coals
As old love is lost
where twisted branch grew
a space to be filled
with life that's as new
These cycles of seasons
They go ever on
shining sweet face
replaced sad one gone
Hearts seem as seasons
in our history of years
summer to fall
and joy into tears
Pray grant me partner
that blows hot nor cold
but steady she steers
dare I wish this so bold ?

Lumbar Back Sprains and Strains
Sprains and strains often result from excessive physical demands on the back. Lifting something too heavy, a sudden fall, car crash, or sports injury can cause soft tissues (ligaments, muscles, tendons) to stretch too much.
Sprains · Strains
The spine includes vertebrae (bones), discs (cartilaginous pads or shock absorbers), the spinal cord and nerve roots (neurological wiring system), and blood vessels (nourishment). Ligaments link bones together, and tendons connect muscles to bones and discs. The ligaments, muscles, and tendons work together to handle the external forces the spine encounters during movement, such as bending forward and lifting.
|
Sprains and strains are similar disorders affecting different soft tissues in the spine. Sprains are limited to ligaments whereas strains affect muscles, tendons, or muscle-tendon combinations.
Ligaments are strong flexible bands of fibrous tissue. Although ligaments are resistant to being stretched, they do allow some freedom of movement. Muscle is made up of individual and segmental strands of tissue. When back muscles encounter excessive external force, individual strands can stretch or tear while the rest of the muscle is spared injury.
To illustrate a sprain or strain, consider what happens when lifting something heavy. Initially muscles are recruited to manage the load. When the load or force exceeds the muscles' ability to cope, the force is shared with the ligaments. When a ligament is stressed beyond its strength, it can tear.

Back pain also known "dorsalgia"
Back pain (also known "dorsalgia") is pain felt in the back that usually originates from the ,muscles, nerves, bones, joints or other structures in the spine.
The pain can often be divided into neck pain, upper back pain, lower back pain or tailbone pain. It may have a sudden onset or can be a chronic pain; it can be constant or intermittent, stay in one place or radiate to other areas. It may be a dull ache, or a sharp or piercing or burning sensation. The pain may be felt in the neck (and might radiate into the arm and hand), in the upper back, or in the low back, (and might radiate into the leg or foot), and may include symptoms other than pain, such as weakness, numbness or tingling.
Back pain is one of humanity's most frequent complaints. In the U.S., acute low back pain (also called lumbago) is the fifth most common reason for physician visits. About nine out of ten adults experience back pain at some point in their life, and five out of ten working adults have back pain every year.
The spine is a complex interconnecting network of nerves, joints, muscles, tendons and ligaments, and all are capable of producing pain. Large nerves that originate in the spine and go to the legs and arms can make pain radiate to the extremities.
Back pain can be divided anatomically:neck pain, upper back pain, lower back pain or tailbone pain.Associated conditions
Back pain can be a sign of a serious medical problem, although this is not most frequently the underlying cause:
- Typical warning signs of a potentially life-threatening problem are bowel and/or bladder incontinence or progressive weakness in the legs.
- Severe back pain (such as pain that is bad enough to interrupt sleep) that occurs with other signs of severe illness (e.g. fever, unexplained weight loss) may also indicate a serious underlying medical condition.
- Back pain that occurs after a trauma, such as a car accident or fall may indicate a bone fracture or other injury.
- Back pain in individuals with medical conditions that put them at high risk for a spinal fracture, such as osteoporosis or multiple myeloma, also warrants prompt medical attention.
- Back pain in individuals with a history of cancer (especially cancers known to spread to the spine like breast, lung and prostate cancer) should be evaluated to rule out metastatic disease of the spine.
Back pain does not usually require immediate medical intervention. The vast majority of episodes of back pain are self-limiting and non-progressive. Most back pain syndromes are due to inflammation, especially in the acute phase, which typically lasts for two weeks to three months.
A few observational studies suggest that two conditions to which back pain is often attributed, lumbar disc herniation and degenerative disc disease may not be more prevalent among those in pain than among the general population, and that the mechanisms by which these conditions might cause pain are not known. Other studies suggest that for as many as 85% of cases, no physiological cause can be shown.
A few studies suggest that psychosocial factors such as on-the-job stress and dysfunctional family relationships may correlate more closely with back pain than structural abnormalities revealed in x-rays and other medical imaging scans.
Treatment
The management goals when treating back pain are to achieve maximal reduction in pain intensity as rapidly as possible; to restore the individual's ability to function in everyday activities; to help the patient cope with residual pain; to assess for side-effects of therapy; and to facilitate the patient's passage through the legal and socioeconomic impediments to recovery. For many, the goal is to keep the pain to a manageable level to progress with rehabilitation, which then can lead to long term pain relief. Also, for some people the goal is to use non-surgical therapies to manage the pain and avoid major surgery, while for others surgery may be the quickest way to feel better.
Not all treatments work for all conditions or for all individuals with the same condition, and many find that they need to try several treatment options to determine what works best for them. The present stage of the condition (acute or chronic) is also a determining factor in the choice of treatment. Only a minority of back pain patients (most estimates are 1% - 10%) require surgery.
Short-term relief
- Heat therapy is useful for back spasms or other conditions. A meta-analysis of studies by the Cochrane Collaboration concluded that heat therapy can reduce symptoms of acute and sub-acute low-back pain. Some patients find that moist heat works best (e.g. a hot bath or whirlpool) or continuous low-level heat (e.g. a heat wrap that stays warm for 4 to 6 hours). Cold compression therapy (e.g. ice or cold pack application) may be effective at relieving back pain in some cases.
- Use of medications, such as muscle relaxants, opioids, non-steroidal anti inflammatory drugs (NSAIDs/NSAIAs) or paracetamol (acetaminophen). A meta-analysis of randomize controlled trials by the Cochrane Collaboration found that injection therapy, usually with corticosteroids, does not appear to help regardless of whether the injection is facet joint, epidural or a local injection. Accordingly, a study of intramuscular corticosteroids found no benefit.
- Massage therapy, especially from an experienced therapist, can provide short term relief. Acupressure or pressure point massage may be more beneficial than classic (Swedish) massage.
Conservative treatments
- Exercise can be an effective approach to reducing pain, but should be done under supervision of a licensed health professional. Generally, some form of consistent stretching and exercise is believed to be an essential component of most back treatment programs. However, one study found that exercise is also effective for chronic back pain, but not for acute pain. Another study found that back-mobilizing exercises in acute settings are less effective than continuation of ordinary activities as tolerated.
- Physical therapy consisting of manipulation and exercise, including stretching and strengthening (with specific focus on the muscles which support the spine), often learned with the help of a health professional, such as a physical therapist. Physical therapy may be especially effective when part of a 'work hardening' program, or 'back school'.
- A British edical journa trial found that the The Alexander techniques was shown in to have long term benefits for patients with chronic back pain.. A subsequent review concluded that 'a series of six lessons in Alexander technique combined with an exercise prescription seems the most effective and cost effective option for the treatment of back pain in primary care'.
- Manipulation, as provided by an appropriately trained and qualified chiropractor, osteopath, physical therapist, or a psychiatrist. Studies of the effect of manipulation suggest that this approach has a benefit similar to other therapies and superior to placebo.
- Acupuncture has some proven benefit for back pain; however, a recent randomized controlled trials suggested insignificant difference between real and sham acupuncture
- Education, and attitude adjustment to focus on psychological or emotional causes -respondent-cognitive therapy and progressive relaxation therapy can reduce chronic pain.
Surgery
Surgery may sometimes be appropriate for patients with:
- Lumbar disc herniation or Disgenerative disc disease
- Spinal stenosis from Lumbar disc herniation, degenerative joint disease, or spondilolisthesis
- Scoliosis
- Compression fracture
Emerging treatments
- Vertebroplasty involves the percutaneous injection of surgical cement into vertebral bodies that have collapsed due to compression fractures. This new procedure is far less invasive than surgery, but may be complicated by the entry of cement into Batson's plexus with subsequent spread to the lungs or into the spinal canal. Ideally this procedure can result in rapid pain relief.
- The use of specific biologic inhibitors of the inflammatory cytokine tumor necrosis factor-alpha may result in rapid relief of disc-related back pain.
Treatments with uncertain or doubtful benefit
- Injections, such as epidural steroid injections and facet joint injections, may be effective when the cause of the pain is accurately localized to particular sites. The benefit of prolotherapy has not been well-documented.
- Cold compression therapy is advocated for a strained back or chronic back pain and is postulated to reduce pain and inflammation, especially after strenuous exercise such as golf, gardening, or lifting. However, a meta-analysis of randomized controlled trials by the Cochrane Collaboration concluded "The evidence for the application of cold treatment to low-back pain is even more limited, with only three poor quality studies located. No conclusions can be drawn about the use of cold for low-back pain"
- Bed rest is rarely recommended as it can exacerbate symptoms, and when necessary is usually limited to one or two days. Prolonged bed rest or inactivity is actually counterproductive, as the resulting stiffness leads to more pain.
- Electrotherapy, such as a transcutaneous electrical nerve stimulation (TENS) has been proposed. Two randomized controlled trials found conflicting results. This has led the Cochrane Collaboration to conclude that there is inconsistent evidence to support use of TENS. In addition, spinal cord stimulation, where an electrical device is used to interrupt the pain signals being sent to the brain and has been studied for various underlying causes of back pain.
- Inversion therapy is useful for temporary back relief due to the traction method or spreading of the back vertebres through (in this case) gravity. The patient hangs in an upside down position for a period of time from ankles or knees until this separation occurs. The effect can be achieved without a complete vertical hang ( 90 degree) and noticeable benefits can be observed at angles as low as 10 to 45 degrees.
- Body Awareness Therapy such as the Feldenkrais Method has been studied in relation to Fibromyalgia and chronic pain and studies have indicated positive effects. Organized exercise programs using these therapies have been developed.
- Ultrasound has been shown not to be beneficial and has fallen out of favor.

How Much Protein Do You Need?
What is protein?
Protein is one of the basic building blocks of the human body, being about 16 percent of our total body weight. Muscle, hair, skin, and connective tissue are mainly made up of protein. However, protein plays a major role in all of the cells and most of the fluids in our bodies. In addition, many of our bodies' important chemicals -- enzymes, hormones, neurotransmitters, and even our DNA -- are at least partially made up of protein. Although our bodies are good at “recycling” protein, we use up protein constantly, so it is important to continually replace it.Proteins are made up of smaller units called amino acids. Our bodies cannot manufacture nine amino acids, so it is important to include all these amino acids in our diets. Animal proteins such as meat, eggs, and dairy products have all the amino acids, and many plants have some of them.
How much protein do we need?
Our protein needs depend on our age, size, and activity level. The standard method used by nutritionists to estimate our minimum daily protein requirement is to multiply the body weight in kilograms by .8, or weight in pounds by .37. This is the number of grams of protein that should be the daily minimum. According to this method, a person weighing 150 lbs. should eat 55 grams of protein per day, a 200-pound person should get 74 grams, and a 250-pound person, 92 grams.Do people who exercise need more protein?
Although it is controversial, there is evidence that people engaging in endurance exercise (such as long distance running) or heavy resistive exercise (such as body building) can benefit from additional protein in their diets. One prominent researcher in the field recommends 1.2 to 1.4 grams per kilogram of body weight per day for endurance exercisers and 1.7 to 1.8 grams per kg per day for heavy strength training.But shouldn’t protein intake be a percentage of total calories?
Quite a few programs and nutritionists quote percentage of calories, usually in the range of 10 percent to 20 percent, as a way to figure out how much protein a person needs to consume daily. This is a rough estimate of a person's minimum protein needs. It works because usually larger and more active people need more calories, so the more calories they need, the more protein they will get.Where this falls down is when people are eating diets which are lower in calories for any reason, conscious or not. People who are ill or losing weight, for example, do not need less protein just because they are eating fewer calories.
What happens if we don’t eat enough protein?
Unlike fat and glucose, our body has little capacity to store protein. If we were to stop eating protein, our body would start to break down muscle for its needs within a day or so.Is it OK to eat a lot more protein than the minimum recommendations?
This is the crucial question for people on diets which are higher in protein than usual, as low-carb diets tend to be. In a review of the research, the National Academy of Sciences reported that the only known danger from high protein diets is for individuals with kidney disease. After careful study, they recommend that 10 percent to 35 percent of daily calories come from protein. They point out that increased protein could be helpful in treating obesity. There is also accumulating evidence that extra protein may help prevent osteoporosis.Extra protein can be broken down into glucose in a process called gluconeogenesis. On low carb diets, this happens continually. One benefit of obtaining glucose from protein is that it is absorbed into the bloodstream very slowly, so it doesn’t cause a rapid blood sugar increase.
What foods have the most protein?
Meat, fish, eggs, dairy products, legumes, and nuts all have substantial amounts of protein.Migraine
What Makes a Headache a Migraine?
Almost everyone gets headaches. You might feel throbbing in the front of your head during a cold or bout with the flu, for example. Or you might feel pain in your temples or at the back of your head from a tension headache after a busy day. Most regular headaches produce a dull pain around the front, top, and sides of your head, almost like someone stretched a rubber band around it.
A migraine is different. Us doctors define it as a recurrent headache that has additional symptoms. The pain is often throbbing and on one or both sides of the head. People with migraines often feel dizzy or sick to their stomachs. They may be sensitive to light, noise, or smells. Migraines can be disabling, and teens with migraines often need to skip school, sports, work, or other activities until they feel better.
If you have migraines, you are not alone. Experts estimate that up to 10% of teens and young adults in the United States get migraines. Before age 10, an equal number of boys and girls get migraines. But after age 12, during and after puberty, migraines affect girls three times more often than boys.
What Causes a Migraine?
Not all scientists agree about what causes migraines. Many believe that a migraine is caused by narrowing and expanding of the blood vessels in the brain. There are also theories that the level of certain chemicals in the brain may affect the nerve system that regulates pain.
Whatever the cause, experts do agree that different things trigger (set off) migraines in people who have them. For some people, eating certain foods brings on a migraine. Others find that sleeping too long (or too little) provokes a migraine attack.
Some common migraine triggers are:
- stress
- menstruation
- skipping meals
- too much caffeine
- certain foods (alcohol, cheese, pizza, chocolate, ice cream, fatty or fried food, lunch meats, hot dogs, yogurt, aspartame, or anything with MSG, a seasoning often used in Asian foods)
- sudden changes in sleep patterns
- changes in hormone levels
- smoking
- weather changes
- travel
Experts believe that the likelihood of getting migraines is inherited. If one of your parents gets migraines, you have a greater chance of having these types of headaches than someone who doesn't have a family history of migraines.
What's a Migraine Attack Like?
Most migraines last from 30 minutes to 6 hours; some can last a couple of days.
Every migraine begins differently. Some people just don't feel right. Light, smell, or sound may bother them or make them feel worse. Sometimes, if they try to continue with their usual routine after the migraine starts, they may become nauseated and vomit. Often the pain begins only on one side of the head. Trying to perform physical activities may worsen the pain.
Some people get auras, a kind of warning that a migraine is on the way. The most common auras include blurred vision and seeing spots, colored balls, jagged lines, or bright or flashing lights or smelling a certain odor. The auras may only be seen in one eye. An aura usually starts about 10 to 30 minutes before the start of a migraine. Some individuals experience a migraine premonition hours to days prior to the actual headache. This is slightly different from auras and may cause cravings for different foods, thirst, irritability, or feelings of intense energy.
Some people with migraines also have muscle weakness, lose their sense of coordination, stumble, or even have trouble talking either just before or while they have a headache.
How Do Doctors Diagnose and Treat Migraines?
Because migraine headaches are different in different people — in some people, for example, they are triggered by hormones; in others, stress and lifestyle influence headaches — how doctors treat someone depends on the type of migraine that person gets.
A doctor may ask someone having migraines to keep a headache diary to help figure out what triggers the headaches. If your doctor has asked you to keep such a diary, the information you record will help the doctor figure out the best treatment. A doctor may also take blood tests or imaging tests, such as a CAT scan or MRI of the brain, to rule out medical problems that might cause a person's migraines.
Part of treatment may involve making certain changes in your lifestyle — like changing your sleep patterns or dietary habits or avoiding certain stress that trigger your migraines. Your doctor may also start you on a pain relief medication or also prescribe medicines that help with nausea and vomiting. Some people need preventive medicines that are taken every day to reduce the number and severity of the migraines.
Some doctors teach a technique called biofeedback to their patients with migraines. This technique helps a person learn to relax and use the brain to gain control over certain body functions (like heart rate and muscle stress) that cause tension and pain. If a migraine begins slowly, many people can use biofeedback to remain calm and stop the attack.
There have also been studies indicating that some alternative methods, such as acupuncture and the use of certain herbs, can help some people. However, it is important to ask your physician about alternative medicines before trying them for yourself. This is especially true of herbal treatments because they can interfere with more traditional methods of treatment.

What is Cord Blood Banking?
When you are in labor, you have three options in regards to what to do with the placenta and umbilical cord blood. You will be able to either trash it (what regularly takes place, a loss), store it for possible use by your baby or a family member, or donate it in public storage that it might be provided to research.
Cord blood contains blood forming, hematopoietic cells. Each year tens of thousands of patients become diagnosed with life threatening medical problems that may be treated by rebuilding the patient's hematopoietic system with working, blood creating cells. Umbilical cord blood is presently being studied as a potential source for blood cells.
Giving cord blood is safe. The cord blood is collected from the umbilical cord after your little one is born. Donation doesn't change the normal birth process. Donating cord blood is free to you and confidential.
To find out more regarding cord blood donation the NMDP has plenty of info including Frequently asked questions, guidelines, participating cord blood banks, hospitals and more.
Certain expectant families may be considering storing for private utilization. Some websites will have a quiz that can let you make the choice between private and public storage.
Think about it. Regardless of your decision, remember that there are multiple ways in which you can donate life.
UK Cord Blood Trends
As of today, cord blood has simply been used as a way to assist in curing conditions such as leukaemia along with other blood diseases that would otherwise need "ordinary" stem cell transplants from bone marrow. But researchers will be looking into the deployment of cord blood in stem cell treatments for a range of other diseases.
A few sicknesses that may one day be treated with stem cells are Alzheimer's disease, spinal cord injury, diabetes, arthritis, stroke, heart disease, cancers, and Parkinson's disease. There are various cord blood banks located in the United Kingdom, one in London, Liverpool, Wirral, and Cardiff. However, any cord blood donated to public sector banks is on a similar basis as blood donation and won't be insured for consumption by the family involved.
Curious families therefore have to pay for personalized storing, unless of course the cord blood is expected to be used in a medical treatment for an ill family member. But the personalized service is not cheap. The program usually costs around 1,000 pounds for 21 years worth of storage - a worth which several scientists continue to say is not worth the price.
It is accurate to note however, that to individuals who have moral issues with the most common method of stem cell transfer (fetal extraction), cord blood continues to grow as the only viable alternative to acquire both the perks of cell regrowth, and life protection.
Hypertension
Blood pressure (BP) as measured by a blood pressure cuff is an estimate of the blood pressure in the large blood vessels in your chest. It is a combination of the force generated by the pumping action of the heart and the resistance provided by the stretch on the blood vessels. In general terms, the more resistance to stretch of these vessels (the stiffer they are) the higher the pressure. Studies have shown that the lower the blood pressure the better but the benefits are less pronounced below 130/80* so that becomes the maximum blood pressure target. Above this number the chance of heart attack and stroke rises steeply. Blood pressure varies from minute to minute and can vary by 50-80 mm with stress or activity. Our goal is to sense what your average blood pressure is and react accordingly.
Who gets HBP? In this country almost everyone! >60% of Americans will have blood pressure >120/80. More than 90% of people over 50 will develop HBP. The usual culprits of stress, lack of exercise, overweight & excess salt account for much of the epidemic but there are some family trends. Offspring of parents with HBP tend to get higher blood pressure earlier in life, occasionally in their teens and twenties.
Why worry? Since, with rare exception having HBP doesn’t make you feel any differently it is sometimes difficult to see the rationale for worrying about a few mm difference in readings. Numerous studies however show a dramatic rise in the incidence of heart attack and stroke with rising blood pressure. In addition HBP is the 2nd leading cause of congestive heart failure and the leading cause of kidney failure. It has also recently been implicated in macular degeneration. HBP damages blood vessels throughout the body on a daily basis and even mild forms need treatment. Fortunately, appropriate therapy reverses most of these risks.
HBP can be prevented and blood pressure significantly reduced by proper diet, including salt restriction, increased fruit and exercise*. Even when HBP is recognized, instituting these changes can be as effective as the most powerful drugs. However once HBP is established, it often requires drug therapy. Fortunately there are now more than 90 drugs approved for treatment and usually drugs can be found that have few or no long term side effects. Often patients eventually require 2 or 3 drug combination therapy for adequate control.
Special Cases: “White Coat Hypertension” in some people even mild stress can raise BP tremendously. Going to the doctors office, getting stuck in traffic or snarling with your boss can cause these changes in moments. It often takes minutes to hours to settle down. Usually stress reduction techniques are more effective than drugs to control these surges.
Renovascular Hypertension. Can be caused by kidney disease or disease of blood vessels leading to the kidney. This can frequently be surgically corrected.
Endocrine (hormonal) related hypertension of several different kinds can lead to intermittent and severe hypertension, especially in young and middle aged individuals. This may require specialized testing to uncover and specific treatment.
*Why report 2 numbers? The blood pressure rises to a maximum during each heartbeat as blood is forced into the arteries by the action of the heart. This is the higher number, the Systolic blood pressure (“systolic” means contraction, as in when the heart contracts. In general terms, the Systolic BP reflects how hard the heart has to squeeze each beat to force the blood along. Between beats, the pressure doesn’t fall to zero but somewhere in between zero and the systolic pressure. This number, the Diastolic BP (diastolic means expansion which the heart does between beats as it fills with blood in preparation for the next ‘systole’) is a reflection of how stiff the blood vessels are. It is reduced with exercise as blood vessels dilate and it rises with age and cholesterol deposition as blood vessels stiffen. It can be thought of as a reflection of the overall ‘health’ of the blood vessels.
High Cholesterol
Medically speaking: “Dyslipidemia”, literally abnormal forms and quantities of several kinds of fatty molecules that can be found in your blood stream. The usual determinants include: HDL, LDL and Triglycerides*. But there are actually several more that can be measured, and have clinical significance including, VLDL and VLDL ‘remnants’.
These fats have varying capability of entering the wall of the blood vessels and forming deposits that can eventually become blockages that lead to heart attacks, strokes and vascular disease. Although there is a strong genetic component to these values, they can be heavily influenced by diet and exercise. By example, more than 80% of Americans over age 50 have unhealthy levels of these fats compared to 10% of Japanese with most of the difference accounted for by diet.
Fats enter your system via diet and are converted by your liver into the variety of forms mentioned. Genetic differences account for differences in the rates of absorption from the gut and rates of conversion. Diet and medication can affect both of these processes and picking the right treatment is critical to the outcome. Traditional determinations of these values can miss certain subtle abnormalities, which can lead to under or over treatment. Complete lipid profiles by NMR (Nuclear Magnetic Resonance) can address these shortcomings and lead to more precise treatment. In certain patients, NMR is critical to the correct diagnosis.
Dietary changes and exercise can be as effective as many of the more than 10 drugs available. These changes are more related to the kind of foods eaten than the quantity. Reductions in certain types of fats and carbohydrates can be more effective than caloric restriction. Additionally, dietary supplements such as niacin, fish oil and red yeast can be useful in reducing risk. Occasionally, there needs to be several attempts to get the right combination of therapy that is both well tolerated and effective. Our lipid clinic staff has more than 8 years experience with these measurements and treatments.
*Since blood is mostly water, cholesterol, a long chain fatty alcohol found only in animal products doesn’t mix well and has to be attached to a protein molecule that is miscible (dissolved) in water. The resultant combination is called a Lipo-Protein. The size of the protein molecule determines the density of the combined structure. Large protein molecules result in HIGH Density Lipoproteins (HDL) whereas smaller proteins result in LOW Density Lipoprotein (LDL). Triglycerides are a combination of three fatty acids and represent most of the fats found in plants and animals (the white streaks in the meat). The vast majority of ingested fats are in the form of triglycerides. Your liver converts ingested cholesterol and triglycerides into the various lipoproteins.
HDL is beneficial and acts as a transport mechanism to take cholesterol back from the blood vessel walls to the liver. LDL in its oxidized form tends to deposit in arteries. Either having a LOW HDL or HIGH LDL is likely to cause arterial blockages. Having a low HDL is actually the most common abnormality in patients with vascular disease and puts you at significant risk even if your total cholesterol is in the recommended range.
Abdominal Aortic Aneurysm
Who is at risk for this? Men (more than women), over 55 years, overweight, smoker or prior smoker with high blood pressure is the highest risk group. Although AAA can be felt with a thorough physical exam, it is notoriously hard to feel a 3 inch bubble under a layer of fat in overweight people. Furthermore, there are rarely symptoms even from large aneurysms although when they are ready to burst, there may be a few days of mid back pain. AAA runs in families with significantly increased incidence in people who have close relatives with aneurysms. Fortunately, ultrasound screening is virtually 100% effective at making a diagnosis and is used to follow small aneurysms to be sure they are not growing dangerously large. See our website for ultrasound availability.
AAA treatment
If you are diagnosed with an aortic aneurysm you should most importantly follow it closely to see if it is enlarging. If the aneurysm is small, less than 1 1/4 inches or about 3 cm it can be followed annually because it is unlikely to grow quickly. It may remain like this for years especially if the underlying problems of high cholesterol and high blood pressure are controlled and smoking ceases. Once the aneurysm gets bigger than 4 cm or about 1 3/4 inches it is increasingly likely to grow more quickly and steadily and should be followed more frequently. Generally repair is considered when the aneurysm reaches about 2 inches or 5 cm. By then the wall is stretched so thin that rupture becomes unpredictable.
Repair can be the tried and true way, to open the abdomen and wrap a Dacron mesh, that looks like fiberglass matting around the aneurysm after cutting it open and removing the weakest segment. This is a big operation with a significant risk of death or disability (1-8% death rate depending on the health of the patient) but is pretty much a permanent fix. The newer alternative is to place a ‘stent-graft’ inside the blood vessel by threading it up into the aneurysm through a blood vessel in the groin. A ‘stent graft’ looks like a slinky with a cloth (again, Dacron) covering. It can be stretched so it is thin enough to go through the smaller groin artery then unfolded in the aorta and attached to the inside of the aorta at the top and bottom. It is a procedure that takes a few hours and people can be out of the hospital the next day. It may be the only way to fix the aorta for those in too sick to undergo the very stressful open procedure. The downsides are that there is a small chance of failure to seal off the aorta at the top and bottom initially and subsequent leaks can occur as the aorta itself continues to weaken over time so close followup indefinitely is needed. All this means you will become very friendly with your vascular surgeon so choose wisely.
Your Heart Pumps about 70 times per minute and 160000 times per day . Imagine IF IT WERE TO STOP! NO IT HAS TO PUMP ON FOR LIFE TO GO ON . ;-)
What this means is basically THE HEART IS A PUMP. When this pump fails due to many reasons it enlarges, the heart muscle becomes flabby , and the Internal pressure rises.
Since the Left side of the Heart is connected to the Lungs - This high pressure Distends the Lung blood vessels making it difficult to breathe.
Picture this like a Flooded Room - after a certain stage it floods the adjoining rooms.
HEART FAILURE CAN BE SILENT : Doctors Diagnose this by tests like Chest X-ray, Doppler Echo cardiogram and Radionuclide scans
What do we do to reverse this >?
Traditionally Doctors Pump Intravenous injections to Drive the fluid out- Out through the Urine and We also give a Few drug injections using Pumps. But nothing seems to work on the long term
All these options are TEMPORARY . The patient remains weak , loses weight Or Becomes
" puffy" due to fluid swelling under the skin and is in grave DANGER !
CAN WE DO ANYTHING RADICALLY DIFFERENT ? WOULD YOU LIKE TO OFFER SOMETHING MORE PERMANENT FOR YOUR NEAR AND DEAR ONES
NEW TREATMENT OPTIONS:
1.ARTIFICIAL HEARTS : We use devices like TANDEM HEART or HEART MATE in case of long standing Heart Failure. These are Artificial Mechanical support devices which take over function of the Heart. In Sudden heart failure we use what we called ECMO (extracorporeal membrane oxygenation).
2. STEM CELLS THERAPY " A new evolving mode of therapy which involves separating Stem cells from Bone marrow and injecting on to the Heart Muscle or into the Cardiac arteries.
3. HEART TRANSPLANT : Established option - but NOBODY ALIVE IS READY TO DONATE HIS/HER HEART ! We need to find Brain dead patients to donate their Hearts - Quite a difficult task!

Endoscopic Vein Harvesting
Endoscopic Vein Harvesting
Also called: EVH, Minimally Invasive Vein Harvesting
Summary
During coronary artery bypass graft surgery, a surgeon takes a segment of a healthy blood vessel (an artery or vein) from another part of the body and uses it to create a detour or bypass around the blocked portion of the coronary artery. That process is called vein harvesting. Traditionally, vein harvesting is accomplished through a lengthy surgical incision in the leg. However, a less invasive method called endoscopic vein harvesting (EVH) is becoming more common and is the preferred method of vein harvesting among centers that are properly equipped. Traditional vein harvesting requires an incision to remove the blood vessel being used for the bypass graft, leaving the patient with a long scar. By contrast, EVH requires one to three small incisions, each less than 1 inch in length. A special video camera (called an endoscope) is then used to allow the physician to clearly view the vein harvesting. |

Bypass surgery - Off Pump Bypass Surgery
Off Pump Bypass Surgery
Also called: OPCAB, Off Pump Coronary Artery Bypass
Summary
Off-pump coronary artery bypass surgery Off-pump bypass involves the same two procedures that are performed during traditional bypass surgery. In the first, the surgeon removes (harvests) one of the patient’s blood vessels – usually the saphenous vein in the leg or the mammary artery. In the second procedure, the surgeon uses the blood vessel to create a detour (bypass graft) around the blockages in the coronary arteries. About off-pump bypass surgery

Bypass Surgery - Coronary Artery Bypass Surgery
Summary
The conorary artery |
During CABG, a surgeon harvests a segment of a healthy blood vessel (either an artery or vein) from another part of the body and uses it to create a detour or bypass around the blocked portion of the coronary artery. As a result, oxygen-rich blood can flow more freely to nourish the heart muscle. Depending on the number of blocked coronary arteries, a patient may need one, two, three or more bypasses.
For various medical reasons, only about one-tenth of CAD patients even need this type of heart surgery. Those who have the surgery need to stay in the hospital for at least three to five days afterward while recovering. After returning home, further recovery time will be necessary.
The CABG is one of the most commonly performed surgeries in the United States. According to the American Heart Association, more than 467,000 CABGs were performed in 2003. Also increasing is the age at which the procedure can be safely performed, as individuals 80 years of age and older have benefited from CABG. Although there are risks associated with any surgery, the potential life-saving benefits of a CABG usually outweigh the risks.
Conorary artery bypass
About coronary bypass
The goal of conorary artery
Depending on which blood vessel is used, one end is either sewn to the aorta or may remain connected to the larger artery where it originated. The other end is attached (grafted) beyond the blockage in the coronary artery. As a result, blood can flow around the blocked area, increasing the supply of oxygen and nutrients to the heart muscle.
Bypass surgery carries some risks, including a less than 5 percent chance of heart damage and a less than 2 percent chance of death. Studies show that women have a slightly higher risk during or immediately after bypass surgery. This may relate to the fact that women who undergo the surgery are generally older and in poorer health, and their smaller body size makes the surgery technically more difficult. However, the overall risks are relatively low when compared to the fact that many of these bypass operations significantly lengthen and improve the quality of the patient’s life. In some cases, the grafted arteries may also become blocked and require a second bypass surgery. Second bypass has slightly higher risks than the initial surgery, because patients are older and other, less optimal blood vessels must be used for the new grafts. However, bypassed arteries can remain functioning for many years, especially when the patient makes diet and exercise adjustments for cardiac health. Therefore, bypass surgery remains a popular choice for physicians treating severe coronary artery disease During coronary bypass surgery

Bypass Surgery - Minimally Invasive Bypass Surgery
Also called: Beating Heart Surgery, MIDCAB, Limited Access Coronary Artery Surgery, Minimally Invasive Direct Coronary Artery Bypass
Summary
Minimally invasive direct conorary artery |
MIDCAB surgery is used to treat the symptoms of coronary artery disease. By bypassing blockages in diseased coronary arteries, surgeons are able to reestablish blood flow to the heart. This will relieve such symptoms as angina (chest pain, pressure or discomfort) and lower the risk of heart attack or other potentially fatal events.
MIDCAB was developed as a less-invasive approach toward bypass surgery.
However, there are a number of drawbacks to MIDCAB. Because the surgeon is working through a smaller incision, the technique is only available for coronary artery disease that occurs in one artery. Multi-vessel disease cannot usually be treated with MIDCAB alone. This shortcoming has been addressed to some extent by the development of hybrid techniques that use MIDCAB surgery in conjunction with balloon angioplasty. In addition, MIDCAB is more technically demanding.
About MIDCAB
MIDCAB (minimally invasive direct conorary artery b MIDCAB addresses these concerns by using a smaller incision in the side of the chest. Working through this smaller incision, the surgeon is able to sew bypass grafts onto diseased coronary arteries. This technique reestablishes blood flow to the heart with much less trauma to the patient and a reduced risk of infection at the site of the surgical wound. On average, patients who undergo MIDCAB may be released from the hospital within 3 to 7 days and can often return to normal activities within two weeks. By contrast, patients undergoing CABG often spend two weeks in the hospital and several months in recovery. MIDCAB surgery may be performed with or without use of the heart-lung machine. If it is performed with the heart–lung machine, the surgeon stops the heart through use of cardioplegia solution, then uses a special system of clamps and shunts to redirect blood flow around the heart. This may be called port access surgery, after the device that is used to reroute blood flow. This technique gives the surgeon the ability to work on a still, empty heart, which increases the level of control over the operation. If the surgery is performed without the heart-lung machine, the surgeon uses a special system of clamps and stabilizers to hold the heart still while the bypass grafts are sewn into place. MIDCAB is used to treat the symptoms of conorary artery disease,
There are also some limitations to the MIDCAB:
Efforts have been made to address MIDCAB’s main limitation, which is its limited usefulness in patients with multiple vessel disease. In some cases, it has been used successfully in conjunction with a catheter-based procedure such as balloon angioplasty. In this case, disease of the LAD will be corrected with a MIDCAB graft, while blockages in other arteries may be treated with balloon angioplasty and stenting. Results for these hybrid procedures are comparable to classic CABG for multi-vessel disease. Not all surgeons are qualified to perform minimally invasive techniques, which require greater skill and experience. Patients interested in determining their eligibility for these techniques and/or finding a qualified surgeon to perform the surgery may wish to seek a second opinion. Before the MIDCAB procedure
