EDUCATION ON PSYCHOLOGICAL RESEARCH ON AGING: COLLEGE PROGRAMS

Tuesday, June 1st, 2010
Whether motivated by a pure thirst for learning or by a lifelong dream of getting a degree, increasing numbers of older Americans are pursuing knowledge in its most intense form: they are returning to college. Faced with declining enrollments, schools are embracing this trend, offering tantalizing inducements to older students.
Reduced tuition. More than a thousand colleges across the country either offer reduced fees or waive tuition completely for people over sixty provided there is space in the classes they want to attend. For instance, fee reduction or no charge to elderly students is now standard at many public (state) universities across the country because over half of the state legislatures, who control the state university system, have enacted such laws.
Special programs or courses. According to a 1985 survey by the American Association of Retired Persons, about 120 colleges across the country have modified their offerings to suit the needs of older students, setting up full-blown programs for “retired professionals” or “senior citizens.” The most comprehensive ones often include a special curriculum, offer transportation to campus, and provide counseling to help older students adjust to college life.
Some of these programs are completely age segregated. Students take courses only with their own group. Others offer a graduated entry into college life. Students begin by taking special courses and then, when they feel comfortable, begin taking the standard offerings at the school. In yet a third variety students in the program are not segregated at all but are given extensive counseling and help with negotiating college life.
Enrolling in a program of this type offers distinct advantages: being buffered from the bewildering job of registering, choosing courses, and finding your way alone, getting your feet wet academically with people your age; having a built-in chance to make friends. There is often a strong sense of camaraderie among the people who attend these “colleges for retirees.”
To find out whether such a program exists in your community, call the admissions office of every nearby college and inquire. Community colleges – because they see their main constituency as adult learners – are likely to be your best bet. State colleges and universities rank second. Special offerings are least likely to be found at private liberal arts colleges. Your local office of the aging should also have information about college programs in your area.
If you want to return to college but cannot find a program of this type, do not be put off. Many college professors are delighted to have older students. Imagine the relief of teaching people who are motivated by a love of learning and whose life experience can add depth to class discussions. By being one of the few gray-haired students on campus, you help enlighten others. Your presence belies the myth that older people are ill and incapable. And in my experience, you are unlikely to be seen as an interloper. Students tend to admire people who after a full working life have the courage and motivation to make a commitment of this magnitude.
You may also be pleasantly surprised about yourself. Studies show that when older people take college courses they tend to get better than average grades, even though many are frightened when they begin – afraid their intellectual abilities won’t measure up.
However, having a good experience depends on choosing your college and courses carefully. Don’t get in over your head; start out slowly so you can gain confidence. Select high-quality courses and, more important, stimulating professors. Since at this time of life you are liberated from the career consequences of not getting A’s, concentrate on having the most intellectually interesting experience you can.
But because you will be such a visible minority in any typical undergraduate institution, be especially sensitive to what the majority wants. You will be seen as an intruder if you talk incessantly or act as if you know it all. If you are auditing courses, understand that your mission is different from that of your fellow students. They are vitally interested in their grades, not just in learning for its own sake. They will not take kindly to your debating fine points with the professor the week before an exam.

CHOOSING NURSING HOME FOR OLDER PEOPLE: INVOLVE THE ELDERLY PERSON IN PLANS

Tuesday, June 1st, 2010
Once the need becomes obvious, have your relative participate in the decision making and plans – if possible, visiting prospective homes and making the final decision about where to go (when the person is competent to do so). Many families wait until the last minute to break the news, reasoning: “What possible good would the extra months of worry do Mom?” However, consider the pitfalls of waiting: you increase the shock of the move by adding the element of surprise; you add the pain of betrayal. The truth is you have been “putting one over,” plotting behind the person’s back. And you rob the elderly person of any chance of control.
Even if your relative has no choice about where to go, breaking the news as soon as possible means choices can be made around the decision. Your mother may be able to arrange to keep her doctor or have her long-standing attendant be there for the first few weeks to make the transition less difficult (it may be psychologically worth the extra expense). She may be able to choose her room or floor, arrange what belongings to take, decide who will come when moving day arrives. Be guided by your knowledge of your relative in following this advice, but also be aware of the research on learned helplessness. In this difficult situation, enhancing control can be lifesaving.
A main fear about nursing homes is the terror of being abandoned, left alone and unloved in an alien place. So as moving day draws near and in the first few weeks, have family and friends make a special effort to rally around. Unless you find that visiting is deeply upsetting, take pains to show your family member you are there. And be as involved as you can for as long as you can.

SLEEP PROBLEMS AT DIFFERENT AGES: PRESCHOOLERS

Thursday, May 21st, 2009

Preschoolers experience the same sleep problems as toddlers. Bad habits and behaviours learned during the toddler period have often become entrenched by this time. During school age most children will have outgrown the problems seen at younger ages, but this is the peak age for nightmares, school terrors and sleepwalking. Some children also have trouble getting off to sleep, or wake very early in the morning. This is often related to stresses in their day to day life, and many children ruminate endlessly about the day’s events or worry about what the next day will bring.

In general, the problems referred to above are those that persist for prolonged periods of time when the child is well and there are no specific family disruptions. It is very important for parents to understand that all children will exhibit altered sleep patterns when they are sick or there are changes to family routine. Even trivial illnesses, such as colds, that do not seem to affect young children much during the day, may affect them at night. They may need more cuddling and become more dependent on parents, and may wake during the night even if they have already established regular sleep patterns.

Similarly, it is quite normal for children to regress at times of stress or family disruption. Children who have to spend time in hospital or have been separated from the parents for some other reason will behave like a younger child for a period of time. One of the commonest reasons children regress, including reverting to more immature sleep patterns, is the arrival of a younger sibling.

RESUSCITATION – GENERAL INFORMATION (PART 2)

Monday, May 18th, 2009

Pinch the patient’s nose between finger and thumb, take a deep breath and apply your lips firmly on the lips of the patient.

If this procedure or blood or vomit around the mouth makes you sick, place a clean handkerchief over the mouth and breathe through that.

If the mouth is injured or if it is difficult to breathe through the mouth, “mouth-to-nose” resuscitation will produce equally good results.

Breathe into the mouth and watch to see if the chest is rising. This will show that your breath is getting into the patient’s lungs. Then sit up and watch the chest collapse. This will show that the air is coming out. Take another deep breath and repeat the exercise.

For a child, breathe at the rate of about 20 per minute, and for adults about 10-15 per minute. As a rule a few quick breaths for a start, then settle into a routine.

If artificial respiration has to be maintained for some time, you may become tired. If there is someone with you, taking turns will make it easier. Keep it up until the patient starts breathing on his own.

If your patient starts breathing, even shallowly, time your breathing to coincide with his.

GOUT – INTRODUCTION

Friday, May 15th, 2009

Mention gout and people are apt to snigger, yet this common disease is no laughing matter.

My introduction to gout was in the comics of my youth, where the Indian Army colonel with the flushed face had his foot wrapped in a turban and his mood was always irascible.

This comic attitude, unfortunately, still persists, so that the sufferer gets little sympathy. But he himself is also likely to regard it too lightly.

Gout, or podagra, is an ancient disease, being well known even before the time of Hippocrates, the “father of medicine” who lived nearly 500 years before Christ. The list of famous men who have had this disorder reads like an historical Who’s Who.

Gout is mainly a male disease — 20 times as many men get it for every woman sufferer. The first attack usually comes in the forties but it is not unusual in men in their twenties — and it can even occur in children.

The trouble is an inborn error in metabolism — the tendency to gout is inherited.

HYSTERECTOMY – INTRODUCTION

Friday, May 15th, 2009

The operation which women most fear is removal of the breast.

This is only done for cancer and the fear of that disease is added to the feeling of disfigurement and loss of femininity.

Hysterectomy, or removal of the womb, on the other hand is usually done for non-cancerous conditions. Yet this operation is often misunderstood by women and as a result leads to many problems which are mainly preventable.

The uterus or womb is an organ, shaped like a pear and about the size of a golf ball. It lies low in the pelvis and can’t be felt through the abdomen unless it is enlarged. The neck of the womb, or cervix, projects into the top of the vagina.

From either side of the uterus come the Fallopian tubes and the outer open ends of these lie over the ovaries. The womb is held in place by ligaments.

The inside of the womb is hollow and lined by tissue called the endometrium.

During a woman’s reproductive life, this tissue is acted on by the hormones, oestrogen and proger-sterone, which are produced by the ovaries.

BABY AND CHILDHOOD DIGESTIVE SYSTEM DISORDERS: WORMS

Friday, May 8th, 2009

There are all kinds of worms. Some you find when digging in the garden. They’re usually long, juicy-looking, slimey things but they are useful (so my gardening friends remind me) for aerating the ground and helping plants grow. Then there are cut-worms which always seemed to chop off my new seedlings at ground level (that’s why I gave up gardening). My older brother, an inveterate and fanatical fisherman in his spare time, often searches the beach for worms when holidaying. He says they make good bait.

But I’m getting carried away… I wish to talk about human worms, or rather worms that inhabit the human system. They are commonly called threadworms, or Enterobius vermicularis if you like scientific names you can hardly get your tongue around. They are called threadworms because they look just like that. A bit of white cotton cut up into little lengths. Only they are very active and can turn and twist and crawl around in a most active way.

Worm infestations are common in children. Often the worms, in large numbers, come from the anal canal and crawl around the external part of the back passage. In fact, if examined at night with a torch, many of these creepy crawling things may be seen in a child with a heavy infestation. Personally, they give me the creeps.

In turn, this produces irritation and itching of the back passage. Often the child scratches, and the area may become sore or even infected if the skin is broken and germs start multiplying. Worms are commonly blamed for irritation, nail biting, nervousness and restlessness, especially during the night. Often vague gastric and nerve symptoms are related to infestations, rightfully or wrongfully. And the worms in their merry-making may become lost; cases have been reported in girls where the worms have reached the vagina and set up irritations there. They are also blamed for some cases of ongoing bed-wetting in children. But often there are few or no symptoms.

Commonly all of the children in a family may be infected. The eggs are highly infectious, and transmitted by scratching fingers from the anal region, they may reach toys, school books, writing implements and other objects that are of common interest. Once the eggs have reached the fingers, it is only a matter of time before they reach the mouth, then the bowel. Here they readily and rapidly hatch out, to set up further infestation. Inattention to adequate hygiene is a major factor in their spread. Inadequate hand washing after handling another person’s property, or before handling food or putting the hands to the mouth, is an important factor.

Treatment

Often it is simple to make the diagnosis, and often parents themselves will see the worms in their children. A simple examination of the stools will often reveal their presence; sometimes the doctor will have an examination carried out to discover either the worms or their eggs. These may be collected from fresh stools, or from around the anal margin. A simple test to detect their presence is done by sticking a piece of cellophane adhesive against the patient’s skin, removing it and replacing it on a glass slide which is then examined under the microscope. The doctor or pathologist may do this.

General hygiene is important. All members of the household should be treated at the same time—or the whole class if the disorder is widespread and has come to the general attention of the teachers.

The hand-washing routine after attending the toilet every time, and before handling or eating food, is essential. Soap and hot water should be used. The fingernails should be scrubbed often with a nail brush and soap. Nails should be kept short at all times, and regularly retrimmed. Regular washing of underclothing and bedclothes is important in getting rid of eggs.

Medication is usually very effective. However, although a single dose is often adequate to kill the organism in the bowel, reinfection is common. Ideally, the whole family is treated at the same time, and proper medical supervision is suggested. Pyrantel embonate (commercially known as Combantrin) and viprynium embonate (Vanquin) have been widely and successfully used for several years. Mebendazole (Vermox) in one single dose is also extremely effective.

Roundworms

Infestation by roundworms (Ascaris lumbricordes) is rare in this country. It is common in tropical countries, and may cause abdominal distention, colic, diarrhoea and emaciation. It is diagnosed when the worm or its eggs are located in stools. The egg may be passed in the faeces into the soil, where larvae develop, and are retransmitted to humans via soil-contaminated fingers or feet. Medical treatment is satisfactory.

Tapeworms

Tapeworms (caused by Taenia saginata from beef or Taenia solium from pork) come through eating inadequately cooked infected meat. General abdominal symptoms, diarrhoea and fever may occur. The parasite sucks blood from the bowel lining. Diagnosis is made when parts of the body are detected in faeces. Medical treatment effects a cure.

Giardiasis

A parasitic bowel infestation, giardiasis has been around for many years, but only for a short time, to any appreciable extent, in Australia. It produces loose bowel actions that do not stop within a few days, as do most bowel upsets. Motions are loose, watery, frothy, offensive. Most doctors consider a diarrhoea that has been persisting for a week or more to be most likely caused by this parasite. It is treated with metronidazole, and proper medical supervision is advisable. Treatment is invariably effective, but recurrences may occur. Most cases have been imported into Australia from European and Eastern lands, and it is now firmly entrenched in this country, especially in the eastern states.

BOTTLE FEEDING

Friday, May 8th, 2009

‘Over the years millions and millions of babies have been successfully bottle fed and have come to no harm. If this kind of feeding is necessary, the mother should accept the fact and not have “hang-ups” over it, for the baby will certainly thrive and develop into a happy and healthy child and adult.

‘When bottle feeding the ideal is to hold the baby as close to your body as possible, for close body contact, once more, increases the mother-baby bond which we believe is important to normal development.

‘Is cow’s milk given straight?’ Karen asked.

‘No, cow’s milk must be modified to make it suitable for the baby. Many excellent commercial brands are available which have been modified to simulate mother’s milk as much as possible. Often the proper amount of vitamins and minerals have been added to provide the necessary requirements.

‘Once more, demand feeding may be practised. But, it has been found that overweight is more common in bottle-fed babies. Whereas a baby will automatically gauge how much breast milk he or she takes, a vigilant parent may think it essential that the baby drain the last dregs from a measured amount of fluid in a bottle. Often the baby is best barometer of food needs.’

‘We often hear horrible stories about breast feeding. Some claim it will ruin your figure; your breasts will look terrible afterwards; that you develop fat on the hips and thighs and around the tummy, and so on. What do you say about this?’

‘The breasts certainly increase in size before the birth and during lactation,’ I said. ‘This is inevitable. After it is all over, the breasts tend to return to their previous size. Sometimes, there is a change in the fat distribution of the mother’s body, possibly because of the various hormonal changes that took place during the whole experience. Many women find breast dimensions similar to the time before they were pregnant. Others find them smaller as the fat deposits have lessened.

‘Many women put on from three to six kilograms (6-14 lb) in weight, from the time before pregnancy to the time the baby is a few months old. What’s more, this weight is often hard to dislodge. It tends to accumulate around the hips, thighs and buttocks and abdominal wall. It is often a consequence of the woman’s eating more during these months, perhaps in the hope of producing enough good-quality milk for the baby. But, commonsense eating habits and a sensible diet after it is all over will help her regain her normal pre-pregnancy shape again.’

‘Normally my breasts are quite small,’ Karen said. ‘They are large right now, but will this affect my milk-producing ability?’

‘No, breast size is no indication of how good your supply of milk will be. Often women with small breasts prove to be the most prolific milk producers, whereas many large-busted women are the opposite. Large breasts simply mean they contain more fat, and this has nothing to do with the milk glands and milk production. Aren’t you lucky?’

“What about taking medicines during breast feeding? Is this safe?’

CHOKING IN CHILDHOOD

Tuesday, April 28th, 2009

Choking is one of the few true emergencies of childhood in which minutes may determine life or death. A swallowed object is the most common and serious cause of choking. Choking is caused by the obstruction of the airway resulting in an inability to breathe. It is easily identified by two key signs: the child frantically tries to breathe, and the child is not able to cry out or to speak.

If choking continues, the child quickly becomes blue, convulsive, limp, and unconscious. If the object completely blocks the air passage, you have only a few minutes to reestablish an airway before brain damage or death can occur.

The objects that choke children are usually of a shape and size to plug the opening into the throat like a cork. Frequent and especially dangerous causes of choking are peanuts, tablets, glass eyes of toy animals, hard or hard-coated sweets, beads, popcorn, and tiny toys or small parts from toys. Solid particles of food from the stomach may choke a child who breathes in during vomiting. A vomiting baby is safest from choking when lying on his or her stomach.

Choking may also occur in a child who has croup. But choking caused by croup is slightly different and is treated differently. A child choking from croup frantically tries to breathe, but the child is still able to speak or cry. See the article on Croup for treatment of that form of choking.

Signs and symptoms

Choking on an object is easily identified by the two major symptoms. There are frantic, unsuccessful efforts to breathe. The child cannot talk or cry.

Home care

Seconds count! Scream for help. A second adult on the scene should phone the police or paramedic squad for help. (Police are usually more quickly available in most communities than an ambulance, the fire department, or a doctor.)

First, give your child one minute to clear the obstruction by his or her own efforts. If this doesn’t work, place your child’s head down over a chair, table, or your lap and pound hard on his back four times. Broken ribs heal; death does not. Support the child’s head and neck before pounding to avoid fracturing the neck.

Only if safer measures fail should you consider reaching into the child’s mouth with a hooked finger or tweezer in an effort to remove or dislodge the foreign body: there’s a good chance of pushing the object more tightly into the windpipe in your desperation to remove it. If your child is not breathing after the object is removed, give mouth-to-mouth resuscitation until trained help arrives.

Precautions

• Never give mouth-to-mouth resuscitation until the obstructing object is removed; to do so may force the object further down the throat.

• Prevention of choking is most important. Examine all toys for loose eyes or other small parts. Keep tablets under lock and key. Do not give peanuts, popcorn, or hard sweets to toddlers. (Clean up after adult parties before children can wander unattended into a room.)

Medical treatment

When the object completely blocks the air passage, the child seldom reaches a doctor in time. However, the object may only partially block the airway, even though you may not think so. Your doctor will operate, on the spot, to open the windpipe through the neck (tracheotomy). Then oxygen, artificial respiration, and intravenous fluids will be given.
