Professional Care From Medicare

October 28th, 2010
Ron Mark asked:




Health is something we seriously begin to think of only after experiencing a more or less severe disorder. In our natural, daily attitude we use health as a premise for making the best of our time, and most of our deeds focus on different issues. Nevertheless, health insurance programs have been designed as a manner to cover this particular aspect of our lives without being necessary to keep track of it constantly, and this proves to be a very suitable manner of dealing with health issues, because it is more or less probable that at a certain point we should experience one disorder or other. Medicare part B, as well as Medicare part D, stands for a health insurance program covering some specific medical services within the perimeter of a wider program, that is, Medicare.

In fact, Medicare part B is meant to cope with tasks that Medicare part A does not. In order to be selected as a Medicare part B beneficiary, one has to meet all the general conditions levied by the entire Medicare program, namely, a certain age – the citizen has to be at least 65 years old – or, if not, they must satisfy other specific stipulations, for instance, continuous dialysis for permanent kidney failure.

The services covered by Medicare part A are as it follows: inpatient hospital stays, home health care, psychiatric inpatient care and hospice care. It is obvious Medicare part A covers a relatively small portion of the entire range of medical services and products. Medicare part B, Medicare part C, as well as Medicare part D have been designed to cover whatever remains uncovered under Medicare part A. Part B of the Medicare health insurance program has a wider range of covered services and programs than part A.

Therefore, the package provided by Medicare part B is much wider, including, just to mention a few, physicians’ services, X-ray therapy and other sorts of therapy, items necessary to fractures and dislocations, a variety of diagnostic tests, durable medical equipment, prosthetic devices, some types of therapy, some vaccines, some preventive services, psychologists’ services and even rural clinic services. This is not a complete list of items and services insured by this part of Medicare. However, before enrolling one should pay attention both to what is and what is not covered by part B.

Medicare part D assists beneficiaries in the purchasing of prescription drugs. Whoever is eligible for other parts of Medicare program and is actually enrolled in one of them may subscribe to part D as well. Irrespective of the specificity of the items covered by Medicare part D, this portion of the program works differently, that is, clients must choose one of the many plans within part D offered by Medicare. The main two programs are the so called stand-alone Prescription Drug Plan, or PDP, and Medicare Advantage Plan, or MA-PD. Due to the fact that part D is designed to work this way, enrollees have the possibility to choose the insurance of a certain class of drugs supposed to be necessary in the coming year. The plans are flexible as they can be changed each year according to the beneficiary’s needs.

Neurobiology: Acetylcholine receptor?

October 28th, 2010
Mithcoriel asked:


I have a question concerning Acetylcholine receptors at the Neuromuscular junction. Hope I translated everything correctly. I need to know if the following statements are true or false. And if you could elaborate, that would be great too:

- made of 5 subunits
-selectively permeable to sodium ions
-similar in structure to the GABA receptor
-binds Acetylcholine and depolarizes the muscle fibre

The Causes Of Urinary Incontinence

October 28th, 2010
Michael Russell asked:




Urinary Incontinence is when there is excretion of urine involuntarily. It is not a disease itself but it can be an indication of an underlying problem, which can be treated. It is more common in women than in men and both young people and old people can suffer from it although it is more common in older women. However, it is not part of the ageing process. It is estimated that more than about 13 million Americans suffer from urinary incontinence. Since it is such an embarrassing topic for most sufferers, they do not like to even talk to their doctors about it. But one must keep in mind, the quicker your doctor knows about your condition, the quicker he will be able to treat you.

There are several causes of urinary incontinence. Some of the common causes of incontinence are:

Temporary Urinary Incontinence

. When children suffer from urinary incontinence, it may be for several reasons. Very often young children have the tendency to wet the bed at night in their sleep. These children may be slower in developing the brain control, which is needed to allow retention of urine all night long. Urine production in these children may be more at night too. Day time incontinence in children may be owing to some kind of development abnormality or have a urine infection. Bed wetting in children is generally a temporary condition and will pass away as they grow older.

. Medications – Some medication such as sleeping pills, muscle relaxants, antidepressants, high blood pressure drugs, medications for heart condition all can give rise to urinary incontinence.

. Constipation – The rectum and the bladder have common nerves as a result when you get constipated it causes over activity of these nerves and causing urine leakage.

. Fluids – If you suffer from stress related incontinence consuming a large amount of water in a short time causes the urine in the bladder to increase thereby putting more pressure on the pelvic floor which may then cause leakage.

Caffeine containing substances such as tea, coffee, coke all make the condition of incontinence worse as caffeine is a diuretic, which makes the kidneys produce more urine and thereby leakage is easier. Caffeine also affects the bladder muscle.

Consuming alcohol can be another cause for incontinence as alcohol is also a diuretic and which stimulates the kidneys which in turn produces more urine.

If you do not consume enough liquids, your urine gets concentrated. This has the tendency to irritate the bladder and make urinary incontinence worse. It also reduces the capacity of the bladder, here again making incontinence worse.

. A very common cause of urinary incontinence is urinary tract infections.

. Over-activity of the bladder can also cause incontinence. Smoking is one such reason people may suffer from an overactive bladder as nicotine has an effect on the bladder muscle.

Persistent Urinary Incontinence

. Pregnancy – Pregnancy can lead to incontinence owing to the following, that is, bladder control nerves may be damaged, pressure of the fetus on the pelvic muscles, urethra and bladder, vaginal delivery causes the nerves around the pelvic floor to become bruised and stretched and also a cut is made in the muscle which enables easier delivery.

. Menopause – When you reach menopause, the hormone estrogen is not produced any more. It is believed that the vaginal tissue weakens owing to this loss of estrogen production. This causes incontinence.

. Incontinence can also occur after radiation or surgery in the treatment of cancer of the prostrate.

. Surgical removal of the uterus may sometimes cause damage to the muscles or the nerves of the urinary tract thereby leading to incontinence.

. An enlarged prostate in men causes the urethra to constrict and blocks the flow of urine. This is another reason for urinary incontinence.

. Inflammation of the bladder wall owing to unknown reasons is also another reason for incontinence. This occurs more frequently in women.

. Obstruction to the urinary tract owing to the presence of tumors can also cause incontinence.

. Diseases like Parkinson’s disease, multiple sclerosis, a stroke or injury to the spinal cord can also be another reason.

. Diseases like arthritis, which sometimes disable an individual from getting to the toilet in time, can also be a cause.
