THE FAT CYCLE

Friday, May 8, 2009 11:47

The process of conversion of fatty acids in the blood stream to triglycerides in the fat cell and back again to fatty acids in the bloodstream is a constant one. The biochemical term for the rebuilding of FFAs into TG in the fat cell is esterification. There is an active cycle of free, or unesterifted, fatty acid uptake into the fat cell which is then re-esterified within the fat cell. Hence there is an ongoing process of lipogenesis, lipolysis and release of FFAs.

Fats which are released into the bloodstream during lipolysis are liberated from their glycerol base and transported to the muscle via the blood to be used as fuel. However, more fat is usually released than is used up. At rest, it has been shown that about 70 per cent of fats released into the bloodstream are re-esterified back into the fat cell, but this decreases to about 25 per cent after the first 30 minutes of a low intensity exercise session. When the exercise is completed, some fats continue to be burned in the recovery process, but about 90 per cent of those released which have not been used up are then re-esterified, and stored back in the fat cell until another day. In exercise then, about one-half of the increase in fat oxidation contributing to the extra fuel supply comes from a reduction of the percentage of re-esterification (fats re-entering the fat cell), rather than an increase in fats being released from the fat cell.

The process of re-esterification may be important for the fat loss process as some studies have shown that the degree of re-esterification, in contrast to the extra fat used up, may be influenced by the post- and pre-exercise meal of the exerciser. Injecting glucose into a fasted subject for example, has been shown to increase the re-esterification of fats back into the fat cell more quickly than it inhibits lipolysis, possibly due to the increase in insulin following a glucose load which then has an inhibitory effect on lipolysis.

BABY AND CHILDHOOD DIGESTIVE SYSTEM DISORDERS: HOW THE DIGESTIVE SYSTEM WORKS

Friday, May 8, 2009 8:31
Posted in category General Health

Have you ever wondered how your tummy system works? When you poke something into your mouth it vanishes. We all know that. But vanish where, and what happens to it?

As you probably know, the bowel, or intestinal, system really begins at the mouth. From the mouth is a continuous canal to the far end, to an opening we call the anus. It is actually a single tube which we arbitrarily divide into segments and call by different names.

The oral cavity is guarded by gums and teeth in front, and the tongue sits in the lower part. A baby is born with gums but no teeth in sight. That’s fortunate for the breast-feeding mum. Have you ever thought how terrible it would be breast-feeding a baby with the full component of twenty sharp milk teeth? Ouch! No, several months pass before the baby is endowed with a first set of teeth.

The oral cavity leads directly into the pharynx, passing the two red tonsils on each side, and the pharynx gives way to the oesophagus, or food pipe. This leads to the stomach via a small valve.

Digestion starts when food mixes with saliva in the mouth. But in the stomach it receives a major boost—the wall is lined with many glands which pump potent acid and some other digestive chemicals, called enzymes, into the mass of food. It tends to become a mixed-up mass, largely fluid in nature.

The stomach is merely a dilated part of the bowel. It houses the food until the valve at the far end allows it to pass into the next part, called the duodenum.

At regular intervals, the stomach valve (called the pyloric valve) opens and the fluid starts its long trek down the bowel. Firstly it traverses the duodenum, which then leads into the small bowel (firstly named the jejunum, and later the ileum) Here various extra enzymes are added, and much of the nutritional elements of the food is absorbed by the bowel wall for use in the body.

At the far end of the small bowel (named ‘small’ not because of its length, for it is very long, but because it is narrow in diameter), it dilates into an area called the caecum. This is where the small bowel connects to the large bowel (‘large’ because it is very wide in diameter, although it is quite short in length, in contrast).

Here the appendix occurs as a small worm-like organ (about the thickness of a pencil). It has an opening where it joins the caecum. It is several centimetres long and has a blind, closed far end; if its opening, or mouth, becomes blocked then trouble looms, for germs can easily establish a foothold and set up an acute infection which we refer to as acute appendicitis.

In the large bowel, fluid (mostly water) is reabsorbed by the walls, making the contents much firmer. From the large bowel, the canal continues as the rectum. There, in the rectum, the residue of the bowel contents is stored until a suitable time when it can be passed. When this occurs, it gently passes down a much narrower tube, called the anal canal.

At the end of this is a valve, called the anal sphincter. When this releases, the final, unwanted debris is expelled from the digestive system via an aperture called the anus. Afterwards, the valve re-closes, and stays closed until another bowel movement is made.

THE SECOND MONTH

Friday, May 8, 2009 8:25
Posted in category General Health

Activity

Baby’s actions start to become a little more smooth. If sitting up, the head still tends to flop but there is greater firmness of the neck muscles; the head can be kept erect for longer periods. The baby instinctively realizes the necessity of keeping the head clear and free from being buried in pillows or objects if lying on the floor. So, at all times there is an increasing effort to hold the head up, at about 45 degree angle. The baby often tires after a few minutes, but this skill gradually improves. Even when lying on the back, the baby often tries to hold the head slightly upwards.

Limb movements (arms and legs) may be less jerky, and much smoother.

Noises may startle the baby, and he or she may twitch involuntarily in the hands and feet if disturbed or if there is a sudden noise.

Objects, such as a toy or your finger, placed in the baby’s hands may still be grasped reflexively; but a tentative effort may be made to knowingly grasp at things. Often the baby will hold objects for short periods before dropping them.

He or she may strike out at near objects, such as mother’s face, if coming within close range.

Talk

The 2-month-old baby still does a lot of crying. This is a good thing, for it helps aerate and expand the developing lungs. The throaty noises of the first month are continued, but the baby will also start cooing in a soft manner. The noises are baby talk, and nothing like a grown child or adult, at this stage.

Mind

Mental development starts to become apparent. Much of the waking time is spent staring at the walls or objects within range. Eye movements wander around in a circular fashion. If there is some object, such as a bright toy, or a light, this will be followed; the baby becomes capable of following an object from one side to the middle line and gradually towards the opposite side, but it then tends to be lost. Things fairly close can be focused on, and the attention kept for increasing lengths of time.

Sudden noises or distractions will cause an obvious body reaction. The baby’s face may show a reaction, such as recognition or possible fear.

Lights, bright colours and moving objects gain the baby’s attention, which may be maintained for a short time. Attention may be fixed on one or two single objects, rather than several consecutively.

The baby tends to grasp for an object that has his or her attention or may strike at it. At this age the baby is able to grasp and retain an object, such as a light toy, for a while but then often drops it. This action tends to be made under control, rather than the automatic reflex it previously was.

The baby becomes stimulated at seeing familiar objects, such as a toy, and happy and often excited at seeing faces he or she recognises such as mother, father, brothers and sisters—and may stare at them intently, often bursting into a smile (as every joyous mother knows) when recognition dawns on baby’s face. Individuals start to be associated with certain favourable actions; for instance, mother and food become synonymous. The baby begins to show a preference for people over inaminate objects. Will often stare at a face intently, giving an impression of profound wisdom. This may end in a happy smile of recognition.

The baby may commence to show a preference for the right or left side, tending to grasp with the right hand, for instance; may sleep on the same side.

Shadows passing over the face, such as waving his own hand in front of him, will make him blink.

Objects as well as moving humans are regarded with a quizzical, intent gaze.

Actions are often repeated over and over, apparently for the sake of movement rather than for any productive end point. Tends to do one thing at a time.

The baby starts to distinguish between different persons, voices, objects.

Relationships

Personality is starting to develop, and the baby starts showing happiness, unhappiness or distress. If upset, he may suck his fingers, thumb or hand to calm himself down. Often he will use this method for slipping off to sleep.

Tends to give a smile of recognition at members of the family. Will react similarly with others. May show signs of stimulation and happiness when seeing people he or she knows. Will intently look at the person. Or will physically react by actively moving the limbs, breathing in and out rapidly with anticipation and excitement, or gurgling and making baby talk. If crying, may stop when seeing a familiar face, or if held or nursed.

However, the baby usually likes being handled and enjoys eating. These are more important than the social aspect of being with others.

If there are others present, the baby will often stay awake for longer periods of time. If encouraged, will ‘perform’, often for hours, and this usually means difficulty settling down to sleep. Pre-sleep-time excitement is often a major problem after these unwise incidents.

Night feeds tend to lessen, to one only.

Bowel actions are often associated with feedings, and the bowel reflex commences. Often there are two actions a day.

The sleep programme tends to change. The baby may sleep for up to seven hours at night and may remain awake for nine to ten hours a day. There may be several sleep periods during the day.

Baby enjoys the warmth of a bath each day, and finds this a very happy occasion as shown by physical movement.

MARIJUANA

Posted in category General Health

Although illegal, marijuana (also known as cannabis) is widely smoked and has attained a degree of social acceptability. While many people believe that marijuana is a benign drug which promotes relaxation, there are several known detrimental side effects. Tetrahydracannabinol (THC), which is found in marijuana, is an immunosuppressive substance. Heavy users can suffer from a variety of immune deficiency diseases. There is also evidence of disruption of the reproductive system of both men and women who habitually smoke marijuana, probably resulting from inhibition of pituitary hormone secretion. The process of ovulation, the menstrual cycle and sperm production are inhibited as a result. Impaired short-term memory is also suffered by many chronic users.

The plant has been used beneficially for glaucoma treatment and pain relief.

THE NATURE OF ANXIETY: THE INDIVIDUAL’S RESPONSE TO ANXIETY

Wednesday, April 29, 2009 8:31

If we are to learn to master our anxiety in an enlightened fashion, we must first know something of its nature. What is anxiety? Unfortunately there is no complete agreement among psychiatrists on this subject, but it is possible to make a number of general statements that help to define anxiety. The ideas which I offer you now are a summary of a theme which I have developed elsewhere.

Most people when they experience anxiety take heed of the warning and do something about it. We do a little less work and so reduce the stream of impulses to our brain, or we take a holiday and remove ourselves from conflicts that have been disturbing us, or we rest and so give our brain a chance to re-establish equilibrium, or we take sedatives and tranquillizing drugs which further aid its integration. This works well enough when the major inflow of disturbing impulses comes from outside sources, but it is generally ineffective when it arises in our unconscious mind. In these circumstances we need something more. We shall see how this can be achieved by helping our mind to sort things out in the relaxing mental exercises which we are about to discuss.

ALLERGIES: HIDDEN ADDICTIONS

Tuesday, April 28, 2009 11:01
Posted in category Allergies

This article offers a new approach to mental and physical health. It shows how our physical environment can be responsible for a wide range of ills, from fatigue to headaches, from arthritis to colitis, from hyperactivity to depression. It also shows how these environmentally related problems can be dramatically relieved in a relatively short time without the use of drugs or harmful procedures.

This new approach is based primarily on diet. But it must be emphasized from the start that the kind of dieting advocated by clinical ecologists has nothing to do with any of the standardized, mass-applicable dietary programs

you may have heard about. It does not advocate the use of any particular nutrient, vitamin, or mineral in the fight against illness. Nor does it summarily ban any food.

Rather, it explains how you or your physician can detect and eliminate those commonly encountered foods and environmental chemicals which may be responsible for your ill health. The emphasis here is on the word you: this is an individualized approach. It concerns the interaction between you and your own particular environment, which is different from anyone else’s. You must discover the foods and chemicals which may be making you feel sick without your being aware of their effect. You must eliminate them from your diet and environment, or learn to control their intake, in order to get well.

For many people, of course, “allergy” primarily means reactions to such inhalants as dusts, pollens, danders, and molds. Patients with these afflictions can also be helped by the methods of clinical ecology, especially when such allergies are made worse by hidden food and chemical reactions. In this book, however, reactions to common foods and chemicals shall be emphasized, and the more serious cases at that. This is because the allergic basis of such problems as hay fever is already well known, while serious reactions to foods and chemicals are still a largely unknown territory to most people. I have practiced this approach to illness throughout my forty-five years as an allergist in the Midwest. I have treated about 20,000 people for food allergies and related problems and have dealt with virtually every kind of chronic illness on an allergic basis. About 7,000 of these patients were primarily suffering from so-called mental problems. The majority of these patients have been helped significantly, often after conventional methods of treatment had failed. Sometimes patients have come to me with a single well-defined ailment. Typically, however, patients have been polysymptomatic, that is, they have had a long history of many problems, physical and mental, which had left them in a general state of misery. The more symptoms they accumulated, the less their doctors have believed their complaints.

Usually, neither patients nor their physicians have suspected food allergy as the root of their problem. This is because most food allergy, by its very nature, is masked and hidden. It is hidden from the patient, hidden from his or her family, and hidden from the medical profession in general. It is said that often the solution to a difficult problem is right in front of your nose, but you cannot see it. In the case of food allergy, the source of the problem is literally in front of you, in the form of some commonly eaten substance which is bringing on and perpetuating chronic symptoms.

Of course, some people do know that they are allergic to certain foods, but generally these are foods that are rarely eaten. A person who is allergic to cashews, for instance, may break out in a rash on the rare occasions when he consumes these nuts. He overcomes this problem by simply avoiding cashews, and that is generally the end of the matter.

Allergies to commonly eaten foods are not so readily detected or avoided, however. Let us say, for instance, that you developed an allergy to milk early in life. At first, this may have resulted in acute reactions, such as a rash or a cough. In time, if the allergy was not recognized and controlled, the symptoms may have become more generalized and less easily detected. Since you probably went on drinking milk or eating milk products almost every day, one day’s symptoms blurred into the next day’s. You developed a chronic disease, such as arthritis, migraine, or depression. It never occurred to you that your daily dose of milk was the source of the problem.

In fact, you were probably “abusing” milk. You had become a milk junkie, a milk-o-holic. It is in the nature of this problem that a sudden loss of the craved substance can cause withdrawal symptoms. Since removal of milk brought on a particularly bad attack of the symptoms, you unconsciously learned to keep yourself on a maintenance dose. Milk in the morning with cereal, milk in your coffee, yogurt for lunch, a glass of milk with your dinner, and, of course, a platter of cheese tidbits before retiring.

Milk is just mentioned as an example. In fact, any food can be abused by overeating it. If a food is eaten in any form once in three days, or more frequently, it is being abused and may become a big problem for the consumer. Since it ordinarily takes between two and three days for a meal to make its way through the digestive tract, the person in question is not free of that food before another dose is added to the stomach. Intolerance to this food may sneak up on the person who eats it after months, years, or even decades of day-in and day-out ingestion. The chief reason these reactions to commonly eaten foods are not readily recognized is that they are part of a pattern of constant reactions in which periods of heightened stimulation may give way to periods of letdown, or “withdrawal” effects. In the beginning of the problem, eating the food has a marked, immediate stimulatory effect lasting up to several hours. Simply by eating a particular food, such as coffee, wheat, or corn, as often as necessary, this “up” effect may be maintained for a relatively long period of time. It is only when such foods are not eaten regularly that a kind of “hangover,” or withdrawal reaction, occurs. Some people find, for instance, that if they sleep late on Sunday morning they wake up with a headache, which usually goes away when they eat. The reason for this is a physical need for some food, such as coffee, which is normally taken early in the morning.

Since the delayed withdrawal effects can usually be controlled by eating some form of the same food, the whole cumulative process of reaction can be called a food addiction. A food addiction differs only in degree of severity from a drug addiction. In all other respects, the two phenomena are remarkably similar. In fact, I have arranged both food and drug addictions in an “addiction pyramid” (Fig. 1). At the peak of this addiction pyramid are heroin and other opiates and natural drugs. These are the most highly addicting substances known. Lesser degrees of addiction can develop, however, to synthetic drugs and to combinations of foods and drugs. Coffee, which is consumed in over 100 billion doses (cups) a year in the United States is a good example of such a mixture.1 In fact, according to experts on addiction, “Any man and any mammal will develop an addiction if certain substances are introduced into the body in sufficiently large doses for a sufficient length of time.”2

The relationship between allergy and addiction may seem a bit complicated at first. Actually, neither of these terms perfectly fits the disease state we are talking about.

Allergy, in this book, is used in its original meaning of any individualized reaction to an environmental substance occurring in time. This would include all those symptoms, such as rashes, hives, coughs, or sniffles, which are identified in the public mind with allergies.

When a person is exposed on an infrequent basis to some substance, and has an immediate reaction to that substance, then the cause and effect of the allergy is apparent to all. Hay fever sufferers, for instance, have little trouble in identifying the source of their problem as pollen.

When the exposure to an allergy-causing substance is constant, however, eventually the acute symptoms will give way to either a period of no symptoms, or to chronic symptoms such as headaches, depression, or arthritis. In other words, the acute symptoms have been suppressed because of the constant nature of the exposure, and the body has reacted by attempting to adapt itself to the problem.

It is this phase which we call addiction, and this most often occurs in response to commonly eaten foods. Unlike the drug addict, however, the food addict does not usually know the object of his desire. In fact, the food addict may not consciously crave any particular food, but may simply arrange his eating schedule so that it always includes the unknown addicting substance. A milk addict, for instance, may always make himself a melted cheese sandwich before retiring, never realizing that he has a physical need for the milk product in that snack.

The food addict resembles the drug addict in one particular, however. Like the drug addict, he tends to alternate between “highs,” or what we call stimulatory reactions, and “lows,” which we call withdrawal reactions. Because of this alternation of “up” and “down” reactions to the addicting substance, the average person can come to understand quite well the essentially addictive nature of common food allergies.

Unfortunately, there is no single word which connotes the longing for an unknown substance, or a craving for something which is hidden not only from the world but usually from the victim himself, but the word “addiction” comes closest to that meaning.

If such food allergies are hidden, the reader may wonder how they were ever discovered. The story of their discovery by Herbert J. Rinkel, M.D., is a fascinating example of medical detective work by one of the pioneers of modern medicine.

Herb Rinkel was a technological genius, an innovator and an inventor with a passion for making cause-and-effect observations of patients and, especially, for measuring them. Under these circumstances, it is not surprising that he should come up with unusual and unique clinical observations. In my opinion, he was the outstanding clinical investigator of his day, as far as the field of allergy is concerned.3

Rinkel was married and had a small child when he entered Northwestern University Medical School in the 1920s. Since they had little money, he and his family subsisted mainly on eggs as their principal source of protein while he was attending medical school. His father, a Kansas farmer, sent the family a gross (144) of eggs a week. From what was later learned about food allergy, it is not surprising that under these circumstances he became highly sensitive to eggs. About this time, he developed a severe nasal allergy. Although he consulted several different physicians, the cause of his profuse rhinorrhea (running nose) was not determined, and treatment was ineffective.

Finding that the medical profession could do nothing for his nasal problem and being familiar with the early investigations of food allergy, he wondered if he might have such an allergy. However, when he tested himself with eggs by drinking down six raw eggs prepared in a blender, he failed to develop any evidence of a reaction. Several years later, however, he happened to avoid eggs along with several other foods, while testing the assumption that a combination of foods might be involved. After eliminating eggs in all forms from his diet for about five days, he ate a piece of angel food cake at a birthday party. Within a few minutes he lapsed into a state of profound physical collapse. Other physicians present were at a complete loss to explain it. Pulse, blood pressure, respiratory rate, neurological and other findings were within normal limits; unconsciousness was his only symptom. The other physicians, as well as Rinkel, after he had regained consciousness within a few minutes, were astounded by this sequence of events.

In thinking about his experience, Rinkel wondered if it might indicate something of importance about the basic nature of food allergy. Perhaps if one had been eating a given food every day, or frequently and regularly, and then omitted it for a period of several days, reexposure might induce an acute, violent type of reaction. To put this concept to the test, he began eating eggs again as formerly. He then omitted eggs again for five days, repeated the egg ingestion, and experienced another bout of unconsciousness. Rinkel next began experimenting with several unsatisfactorily treated, chronically ill patients from the clinic where he worked. By 1936, he had confirmed and extended his observations of masked food allergy. Although these findings were reported in several local allergy journals, his major article op. masked food allergy was not accepted for publication by the editor of the prestigious Journal of Allergy. Rinkel was very upset by this rejection and made no further attempt to publish on this subject for the following eight years. During this time he worked out the basic nature of masked and unmasked food allergy.

What foods did Rinkel and others find caused such hidden allergies? The most common culprits, quite logically, were the most commonly eaten foods. In North America at this time these include coffee, corn, wheat, milk, eggs, yeast, beef, and pork. In fact, any food, eaten repeatedly, could cause allergic reactions. If a person did not eat one of these foods, the chances are he would not become allergic to it. On the other hand, if a food were taken more than once every three or four days (and most of those on the above list are), then they may possibly cause trouble.

Americans have become largely unaware of what goes into their stomachs. The increased consumption of prepared food, including restaurant food, often leads us to eat blindly. Many people still do not read labels, and labels are often incomplete or inaccurate. Some labels, for example, list “sugar” as an ingredient, but rarely say whether this means cane, beet, or corn sugar.

The result of this situation is that many people think they are not consuming a particular food, when they are in fact having it every day. A good example is corn: you may not eat corn as a vegetable very often, yet eat it at practically every meal in the form of corn sugar (dextrose or glucose), corn syrup, cornstarch, corn oil, or as a hidden ingredient in other foods, such as beer or whisky. Both Rinkel and I showed that allergy to corn was, in fact, a dominant form of food allergy in North America.

In this book, therefore, when I speak of “eating” a food, I am referring to consumption of that food in any form in which it enters the body, not just in its most obvious shape. Part of the difficulty in unmasking food allergy stems from the hidden way in which various foods enter the diet.

As I have indicated, the continuous intake of such a food may eventually result in a response which resembles addiction: one has an unconscious need to consume a particular substance in order to feel relatively well. Being deprived of that substance brings on a feeling of illness, whose nature depends on the individual in question. The American humorist Don Marquis once said that “ours is a world where people don’t know what they want and are willing to go through hell to get it.” This is a good description of the food addict, who doesn’t know the exact nature of the food he craves, but is willing to eat compulsively, to the point of addiction, in order to get it.

The addictive response is broadly composed of two phases: 1) an immediate improvement of chronic symptoms of illness, such as tiredness, headache, fatigue, or aches and pains, when the food is eaten and then 2) a delayed hangover unless the addicting food or drink is taken on schedule. Each individual establishes his own addiction routine, his own pattern of ever-decreasing periods between food “fixes.” By taking his addicting food, the addict keeps himself in a relatively “high” state and postpones feelings of letdown, hangover, or pain which follow withdrawal of the addicting food.

Since the craved food results in pleasure or at least the absence of pain when it is eaten, the confirmed “food-a-holic” may indignantly reject the suggestion that his “favorite” food or drink is bad for him. Why, that’s the very food that makes him feel good! This is part of the paradoxical nature of food allergy—that one’s best friend, foodwise, often turns out to be one’s worst enemy.

MEDICAL TESTS FOR CHILDREN: LUMBAR PUNCTURE OR SPINAL TAP AND CAT SCAN

Tuesday, April 28, 2009 10:09
Posted in category General Health

Lumbar puncture or spinal tap

A lumbar puncture, also known as a spinal tap, is the method used to obtain a sample of cerebrospinal fluid for testing. Cerebrospinal fluid is a clear liquid that surrounds the brain and the spinal cord. In a lumbar puncture, which is usually done in the hospital, a needle is used to penetrate into the spine at the lower end, between two spinal bones called lumbar vertebrae, and draw out the fluid. The pressure in the spinal column can be measured at the same time. The fluid is examined to see if it is clear or cloudy and to see if it contains any blood. It is then tested for viruses, bacteria, and other signs of infection.

A lumbar puncture may be done to test for meningitis, encephalitis, brain hemorrhage (bleeding in the brain), polio, and other nervous system disorders. Under the usual circumstances, there is no risk from a lumbar puncture. If the spinal fluid is under extreme pressure, however, the procedure carries some risk of complications; a different technique is then used to minimize risk.

Cat scan

A CAT scan is a sophisticated type of X ray. The initials stand for Computerized Axial Tomography. In a CAT scan, a series of special X rays are made of a part of the body such as the head or the torso. The patient is placed in a tunnel-like opening in the machine, and does not have to be repositioned for each picture as is done for ordinary X rays. This way, pictures can easily be taken from many different angles. A computer then assembles those X rays into a single picture which shows a cross-section of that part of the body. The whole process takes only a few seconds. CAT scans are used to find abnormal growths or other problems in areas that are inside the body and therefore difficult to see without time-consuming and potentially dangerous exploratory surgery. For example, the brain can be examined for an abnormal growth without opening up the skull.

CAT scans are usually done in a hospital. The equipment for the procedure is expensive, and a limited number of scanners is available. Sometimes a patient must be transported to another hospital, or even to another town, for this test, because a scanner is not available in his or her home town.

BRONCHITIS AND CHILDREN

Tuesday, April 28, 2009 9:24
Posted in category General Health

Bronchitis may be thought of as a cold that spreads to the windpipe (trachea) and to the air passages leading into the lungs (bronchial tubes). It may start with signs of a common cold, with nasal congestion and discharge, sneezing, watery eyes, and scratchy throat. Bronchitis may also develop without any cold symptoms appearing first.

Most cases of bronchitis are caused by viruses. These viruses cannot be cured by antibiotics. Bronchitis is contagious and is passed on in the same manner as a cold. If the disease occurs frequently, the child may have an underlying allergy. (Sometimes children with asthma tend to have repeated attacks of bronchitis.)

Signs and symptoms

The major symptoms of bronchitis are a dry, hacking cough; a low-grade fever (37.8°C, oral; 38.3°C, rectal) or no fever; and tightness and pain in the center of the chest. Often the child experiences a loss of appetite and feels generally weak and uncomfortable. After a few days the cough loosens. Occasionally, a rattling sound can be heard in the chest when the child takes a breath, but there is never any real difficulty in breathing (except that caused by nasal congestion). The entire illness may last more than a week.

There is rarely high fever or prostration (extreme exhaustion or collapse). There is never pain on the side of the chest. No blood appears in the sputum (discharge coughed up out of the lungs).

Home care

Treatment for bronchitis is similar to treatment for the common cold. Limited activity is recommended during the fever stage and the worst of the cough. Give aspirin or paracetamol for fever and body aches. Phenylephrine or oxy-metazoline nose drops may be used. A humidifier or vaporizer aids breathing. If the cough is exhausting or keeps the child from sleeping, cough medicine might help. Encourage your child to drink liquids to avoid dehydration (loss of body fluids).

Precautions

• See your doctor if any unusual symptoms occur, such as pain on the side of the chest or blood in the sputum.

• See your doctor if bronchitis occurs more than once a year.

• See your doctor if the condition worsens instead of improves after three to four days.

• Do not use oral decongestants, which may tighten the chest and aggravate a dry cough.

Medical treatment

Your child’s physical examination should include a careful examination of the chest. Throat or sputum cultures, a chest X ray, and a blood count may be taken. If bronchitis occurs frequently, your doctor will investigate the possibility of an allergy, a foreign body in the bronchial tubes, or a lowered resistance to infection. The use of antibiotics and some types of cough medicines is debatable. Antibiotics usually are not helpful for most types of bronchitis (those caused by virus), and some cough medicines can aggravate more than relieve the condition. If a child has repeated attacks of bronchitis, your doctor may give epinephrine by injection to determine if the child has an allergy. If epinephrine relieves the symptoms, it is likely the attacks are caused by an allergy.

ABOUT IMPOTENCE

Thursday, April 23, 2009 7:04

What is it?

A condition in which a man is persistently or recurrently unable to obtain or maintain an erection of sufficient rigidity to have intercourse. It can have a partly physical basis or can be a form of unconscious sex avoidance.

What causes it?

Most impotent men believe that there is a physical cause for their impotence but this is probably not so, and psychosexual therapy can often do much to cure them. However, there is little doubt that zinc deficiency, for example, is much more common than is realized and this provably contributes to the problem. There are scores of causes for impotence-here are just a few of them.

• Any painful condition of the penis, such as a tight foreskin.

• Diabetes is a common cause-about half of all middle-aged insulin-dependent diabetics have sexual problems, the most troublesome of which is impotence.

• Any arterial disease that produces a reduced blood supply to the penis is a well-recognized cause.

• Certain diseases of the nervous system such as multiple sclerosis and paralysis.

• Certain operations, including prostatectomy and pelvic surgery for cancer.

• Certain hormone deficiencies.

• Psychological illnesses such as depression.

• Alcohol.

• Zinc deficiency.

• Smoking.

• Drug abuse.

• Medical drugs, especially those for high blood pressure, and anti-depressants.

• Various psychological reasons, including: the man unconsciously thinking of his partner as his mother; guilt about sex; such a degree of anxiety that he is unable to relax and let an erection occur; a fear of women and their ‘purity’; a fear of VD or unwanted pregnancy (this is especially common in extramarital impotence); misperceptions of women’s sexuality generally; and many more.

• Earlier failures-leading to the belief that he will always fail.

• Old age. As men age they tend to become less potent. Few men in their nineties are potent.

• Any of the reasons that cause a loss of sex drive.

• Doubts about the relationship with the partner.

• Hostility towards the woman (often not recognized consciously).

• Fear of being detected (in the parental home or in a public place, for example).

• Tiredness, either mental or physical.

• Latent homosexuality-the man would unconsciously rather be with another man and not his partner.

• Fear of hurting his partner, especially after a baby or an operation on the woman.

• An over-demanding woman.

• Stress-from, for example, work, money, home, business problems, or worries about children and parents.

Clearly these causes are many and complex and will often need to be sorted out with the help of a professional who is expert in the area.

FACTORS INFLUENCING THE DEVELOPMENT OF HEART DISEASE

Air pollution causes heart disease

The burning of fossil fuels is thought to increase your risk of heart disease. Tiny airborne particles that are released from power stations, motor vehicles, burning wood and steel and cement plants are light and can travel 2000 to 3000 kilometers in air currents. According to Markus Amann, from the International Institute for Applied Systems Analysis, these particles cause heart disease by inflaming the heart membranes. The United Nation’s Economic Commission for Europe is planning to set up a team to investigate the problem.

Lack of sunlight raises your cholesterol

When our skin is exposed to sunlight, the cholesterol in our skin is converted into hormone precursors, which are then converted into vitamin D and testosterone. The cholesterol in your bloodstream then moves into your skin to replace what was lost. Therefore, regularly getting small amounts of sunlight on your skin can help to keep your cholesterol down, your bones strong, and your libido healthy, through increased testosterone production. This may be one of the reasons why shift workers have twice the rate of heart disease of the general population.

Too much iron can give you a heart attack

Iron is an essential mineral in our body that is mainly required for the transport of oxygen in the bloodstream. However, too much iron can do a lot of damage in your body. Iron has an oxidizing effect in our body, and if you have too much of it, it acts as a free radical. Iron can oxidize the cholesterol in your bloodstream, turning it into a much more harmful state.

Excess iron can also cause damage to the inner lining of your arteries (endothelium), making you more likely to develop atherosclerosis. It seems that too much iron interferes with the action of nitric oxide. This is a substance produced by our artery walls that dilates blood vessels, and has an anti inflammatory effect on the arteries. If you have some risk factors for heart disease, such as high cholesterol, a fatty liver or diabetes, it is very important for you to have a blood test for iron. Menstruation in women, and blood donations by men, are considered to offer protection against heart disease because of the loss of iron. One study published in the British Medical Journal found that male blood donors have an 86 percent lower chance of having a heart attack than non-donors.

Sleep apnoea

Severe sleep apnoea is a bigger risk to your heart than smoking or high blood pressure. If left untreated, sleep apnoea can make you five times more likely to have a heart attack. Sleep apnoea is where the muscles of the back of the throat and tongue relax so much during sleep that they collapse and block the airways. When this happens a person stops breathing. After a few seconds to a minute, the brain detects that not enough oxygen is getting into the body. The brain then forces you awake so that you can take a breath. Typically this recurs several times each night. The common scenario is that a person will be snoring during their sleep, stop breathing momentarily, and then start choking or coughing. They fall back asleep straight away and start snoring again.

People who suffer with sleep apnoea are usually very sleepy during the day and experience poor concentration and irritability. The most common causes of this condition are obesity, alcohol consumption in the evening and nasal congestion. Not everyone who snores has sleep apnoea. This condition is diagnosed via an overnight sleep study, whereby you spend a night at a hospital and electrodes are taped to various parts of your body to monitor sleep quality and breathing.

Sleep apnoea can often be totally cured with diet and lifestyle champs such as losing weight, reducing alcohol intake, especially in the evening, and treating excessive mucous congestion in the sinuses and respiratory tract. Sleeping on your side rather than back usually helps too. More severe cases require the use of a CPAP (nasal Continuous Positive Airway Pressure) machine. This is a nasal mask worn at night which pumps air into your upper airway to keep it open. This method is very effective but it can be difficult to get used to. Treatment with a CPCP machine removes the risk of heart disease incurred by sleep apnoea.
