Pain and Mood: Depression Hurts

Every child knows that a scraped knee can bring tears as well as blood. Physical pain always has emotional overtones, and we now know that emotional distress can be physically painful. Depressed people suffer three times their share of chronic pain, according to recent studies, and people in pain are at high risk of depression. Some studies suggest that if physicians tested all pain patients for mood problems, they might discover 60 percent of all undiagnosed depression. If you’re struggling with either problem, there’s a good chance you’re suffering from both of them.
The link between sensory pain and emotional pain is rooted in the nervous system. Both are governed by the same neurotransmitters (chemicals such as serotonin, norepinephrine and substance P), and both are processed in the same parts of the brain. When the circuitry is working properly, pain and anguish are self-limiting: we recoil from unpleasant experiences, the feelings fade and life goes on. But if a problem persists, or the circuitry malfunctions, the brain’s distress signals stay switched on, with devastating consequences. One study found that over a two-year period, a person with a history of migraine was five times more likely than average to have a first episode of depression. In a related condition known as fibromyalgia, the brain’s overactive pain centers cause pain and tenderness in muscles all over the body. Not surprisingly, at least 30 percent of fibromyalgia sufferers go on to experience depression as well.
The bright side of this story is that treating chronic pain can often help alleviate depression, and vice versa. The older antidepressants, known as tricyclics, have well-known analgesic effects—even at lower doses than depressed patients receive. Newer antidepressants such as Prozac, Zoloft and Paxil (the selective serotonin reuptake inhibitors) may not be quite as effective, but they’re safer and may be easier to tolerate. Almost any drug that relieves an underlying psychological condition can help control pain. In pain rehabilitation centers, specialists often combine these medicines with common analgesics such as aspirin, ibuprofen and acetaminophen.
Drugs aside, mind-body techniques such as meditation, hypnosis and progressive muscle relaxation can help modulate emotional responses to pain. And psychotherapy can teach us to recognize thoughts and behaviors that amplify our feelings of distress. No one escapes having those feelings from time to time. Fortunately, they don’t have to dominate our lives.

HOW DISCOUNT DRUGS FELL OUT OF THE MEDICARE LAW

Whenever congress goes about the legislative process, it takes care of some people and denies protection to others. The Medicare bill was no different, as can be seen in the fate of three provisions with direct influence on drug prices. Those that would have reduced prices disappeared from the law, while one that protected high prices remained.

Even while addressing the issue of safety, Gutknecht pointed to what he believed to be the main motivation for resistance to such legislation: “Now, when we talk about safety, I think the real question is, Who are we protecting from whom? Who is really being protected by our FDA? More and more of us are coming to the conclusion that the only people really being protected are the big executives of the large pharmaceutical companies. We ask ourselves, Why are Americans, the world’s best customers, paying the world’s highest prices? … I am a Republican. There is nothing wrong with the word profit, but there is something wrong with the word profiteer.” Gutknecht’s amendment made it all the way to the secret joint House-Senate conference, where it was deleted by members of his own party. But as so often is the case in the congressional editing process, no one is claiming credit.
Another provision in the bill, related to pricing but with the opposite goal, managed to stay in the law. “Subpart 2, Prescription Drug Plans” contained three paragraphs that will have an enduring effect on how much America’s elderly pay for prescription drugs:
“(i) Noninterference. In order to promote competition under this part and in carrying out this part, the Secretary–
“(1) may not interfere with the negotiations between drug manufacturers and pharmacies and [prescription drug plan] sponsors; and
“(2) may not require a particular formulary or institute a price structure for the reimbursement of covered … drugs.”

Drop sexual politics

This year, can we resolve to get over the idea that his holding your wrists down to the bed means he’s a Neanderthal brute, or that she’s a bitchy feminist if she wants to ride you like Seabiscuit? Sex is supposed to be joyful, exhilarating, intimate and revealing. If the mail coming into Sexploration is any indication, many of us are way too eager to find some hidden political meaning behind desire online pharmacy shipp international.

Gastroesophageal Reflux Disease - Patients Suffer For Two Years Before Seeking Medical Help

People are suffering with distressing symptoms of gastroesophageal reflux disease (GERD) for an average of two years before seeking care and advice from their primary care physician.1 Results from the Burning Desires survey, revealed today, indicate that this may be due to a perception amongst sufferers that while over-the-counter (OTC) medications are effective, prescription medications will not help. This is despite the fact that prescription medication in the form of proton pump inhibitors (PPIs) has been proven to provide relief from one of the main symptoms of GERD - heartburn - within five days in most people.2

Symptoms such as heartburn place a considerable burden on sufferers’ lives, with more than 80 percent of those surveyed having made lifestyle modifications, such as avoiding certain foods, to try to control their symptoms.

Commenting on the results of the survey, Professor Roger Jones, Wolfson Professor of General Practice, King’s College London said that the results of the survey highlight that many GERD patients are suffering unnecessarily.

“There is a mistaken belief amongst many GERD sufferers that prescription medications will not be able to help them, as they feel they can control their symptoms with over the counter remedies. However, these remedies only relieve occasional heartburn and should not be relied upon for long-term symptom control. It is important that sufferers visit their physician to discuss their disease as they may be prescribed a more effective treatment, such as proton pump inhibitor therapy, which can have a significant impact on controlling symptom severity and improving quality of life.”

Using a seven-point scale, with seven being the most important, participants were asked to rate the influence that various factors had on restricting or inhibiting them from consulting a primary care physician for care and advice about their disease. Amongst 924 un-diagnosed patients, the most common factors included a belief that their OTC medicine was effective (mean score = 4.4), they had suffered no increase in the severity or frequency of symptoms (mean score = 4.1) or that their symptoms were already controlled (mean score = 4). In addition, the belief that prescription medications could not help had an influence on preventing them visiting their physician (mean score = 3.8).

In contrast to this, of those 984 diagnosed GERD sufferers surveyed, the most influential factors that drove them to visit their physicians for advice and care included a belief that their physician could help (mean score = 5.8), a belief that their physician would take them seriously (mean = 5.7) and that effective treatment options existed (5.7).

Further data from the Burning Desires survey show that GERD sufferers who did seek medical advice and who were treated with PPI therapy reported a greater improvement in their symptoms compared with those on alternative treatments, including H2-receptor antagonists or antacids. In the seven days before the survey was undertaken, 31 percent of PPI users questioned had had no symptoms, compared to only 8 percent of those survey responders who were using alternative methods to control their symptoms. In addition, self-treated individuals were significantly more likely to report heartburn in the seven days before questioning (83 percent) compared to those who were medically treated (67 percent).

The latest PPI, Nexium (esomeprazole) can provide freedom from heartburn within five days in most people and has been shown to provide an improvement in areas of health-related quality of life (HRQL).2,3 Nexium� works by deactivating the proton (acid) pumps that produce stomach acid, thus reducing the amount of acid that is in the stomach, helping to treat heartburn and other symptoms of GERD. Several comparative clinical trials with more than 15,000 patients with Nexium�, including the EXPO, the EAZEE and Metropol studies, confirm that Nexium� provides superior acid control which translates into clinical benefits.2,4,5,6,7,8 Nexium� is only available on prescription. The most common side-effects with Nexium� are headache, diarrhoea, and abdominal pain, which occur in around one per cent of patients.

Campaign targets leading cause of blindness

An international initiative has been launched to combat an eye disease that has blinded 6 million people in the world’s poorest countries.
Trachoma is a painful infection that is spread when children wipe their eyes and pass on the disease to others.
Pharmaceutical company Pfizer has joined forces with health officials in five of the most afflicted nations to distribute an antibiotic that can successfully treat the disease.
The antibiotic known as Zithromax is so powerful that patients may need just one dose a year.
The campaign, to be launched in Ghana, Mali, Morocco, Tanzania and Vietnam, will also teach children that simply washing their faces with clean water will get rid of the infection.

Tremendous impact

Children spread disease by rubbing their eyes
Pfizer spokeswoman Paula Luff said: “The disease is largely forgotten, but the impact is tremendous on families and communities.”
Trachoma was once a worldwide threat. Napoleon’s troops encountered it in Egypt in 1798. It blinded early Americans, and was one of the most common causes for rejecting would-be immigrants to the US at Ellis Island.
With improved sanitation, trachoma was eliminated from North America and Europe. But the disease remains the world’s leading preventable cause of blindness, infecting 150 million people in developing countries.
The infection is spread person-to-person, mostly by children as they rub red, sticky eyes or flies pick up the germs from faces which have not been washed because clean water is so scarce.
Repeated infections over the years scar the upper eyelid, eventually causing the thin tissue to recede so that the eyelashes literally scratch the cornea, and in many cases cause blindness.
Some people wear tweezers around their necks to pluck the painful lashes, but they can grow back.
Painful treatment
Since the 1950s, treatment has meant applying an ointment of the antibiotic tetracycline directly to the eyes twice a day for six weeks.
Thick as toothpaste, the ointment stung and children in particular did not see the course of treatment through.

Now Pfizer-sponsored studies show that one dose of oral Zithromax, widely used to fight other infections, works just as well.

The new campaign will include:

Training nurses to perform a simple operation to stop the eyelashes damaging the eye.
Teaching children to wash their faces.
Distribution of Zithromax.
Water sanitation programmes.
The campaign has been endorsed by the World Health Organization, which hopes to eliminate the disease by 2020.

Doubts

Professor Neil Poulter, an expert in cardiac medicine at the National Heart and Lung Institute, told the BBC News website that there had been doubts about the effectiveness of atenolol for some time.
He said it was possible that the drug increased blood sugar levels, or had an adverse effect on cholesterol.
He said the National Institute for Clinical Excellence recommended a combination of beta blockers and diuretics to treat hypertension.
However, the British Hypertension Society had concerns that the combination could increase the risk of diabetes.
Professor Poulter said a major trial of 19,000 patients was underway in which the beta blocker/diuretic combination was being compared to another combination of drugs - an ACE inhibitor and a calcium channel blocker.
However, he said there was no reason at this stage why people who were taking beta blockers should stop their medication.
“There a very good reasons why patients should not suddenly stop taking beta blockers. If they were to stop then it should be done gradually and under the close control of a physician.”
The drug was originally developed by drug giants AstraZeneca, whose patent expired in 1991.
A spokesman for the company said: “We believe that this study is inconclusive.”

More challenges

Under US law, Pfizer could have launched its own lawsuit against Dr Reddy’s to try to halt the generic drug, but it has not done so.
Pfizer is the world’s biggest drugs company. It has said its profits target this year assumes that none of its drugs will face cheap generic competition.
But anti-convulsant Neurontin, hypertension drug Norvasc and Zoloft are all the subject of court battles over copycat or altered versions.

Diabetic Complications

These are some of the main negative consequences of the attempt to control the diabetic condition - the principal aim being good health, which it is sometimes difficult to appreciate as a significant achievement.

The main complication of ‘over-control’ is hypoglycemia, which can really ruin your day - and the days of the people around you. Such complications are typically short-term, however, as it is comparatively easy to treat by the consumption of sugary food or drink. As it’s very difficult to maintain a normal lifestyle when continuously twitching, soaked in sweat and unable to control your limbs your diabetic sufferer will, hopefully, be prepared for this eventuality online pharmacy shipp international.

Not all hypo-incidents are quite so severe, but IDDM hypos are typically more dramatic than NIDDM hypos, due to the larger doses of insulin involved. The ’secondary complications’ of hypoglycemia are not so easy to treat. Injuries due to car crashes undergone while under the influence of hypoglycemia, for example, are difficult to dismiss, and it is quite easy to smash your own head open while banging it on the ground in a fit of hypoglycemic frustration.

A related complication of hypoglycemia is the phenomenon known as ‘hypoglycemic unawareness’, which, typically, affects insulin-dependent individuals undergoing intensive therapy. Widely encountered by insulin-dependants after the introduction of ‘human’ - or genetically engineered - insulin analogues during the 1980s11, this phenomenon eliminates native adrenal responses to an approaching hypo, meaning that the diabetic cannot ’see them coming’. With habituation to lower BSLs, this also means that diabetics on intensive therapy are more prone to lose the behavioural symptoms which might characterise a hypoglycemic episode from the ‘outside’ until the episode is so well advanced that it is difficult to resolve without medical attention. As intensive therapy implies more injections12 - and requires more blood testing - than would occur otherwise, this phenomenon increases the number of hypoglycemic episodes that the diabetic is likely to have. As a result, due to the increasing popularity of intensive therapy in preventing other complications, hypoglycemia has become a more visible and feared issue in the treatment of IDDM than it was previously.

The notable potential complications of ‘under-control’, or maintaining BSLs which are too high, are generally longer-term, and include diabetic retinopathy13, diabetic neuropathy, diabetic nephropathy14, gangrene and subsequent amputation, impotence15 and lesser circulatory disorders. In the shorter term, a high BSL can make you feel bad - moody, short-tempered, lethargic, prone to urination - but there are fairly straightforward ways of dealing with this problem. Only if the high BSLs become habitual do you have cause to be overly-concerned.

It is widely believed diabetic complications are the direct consequence of the medical profession’s increasing ability to treat the diabetic condition, and apply as outcomes across all types of diabetes. They occur in insulin-dependent diabetics mostly because the administration of insulin allows them to live long enough for the complications to present, rather than simply to be killed by the condition itself. Diabetic complications are one of the chief burdens on the hospital systems of several developed countries, and the public health strategies of these countries for dealing with IDDM typically involve addressing a potential immunisation against the condition and instruction in the avoidance of complications, rather than a ‘cure’ for IDDM itself, as most sufferers hope for. Some of the complications may also apply to insulin-dependent individuals who remain untreated, although IDDM more often causes death before the complications become a burden - as they do to treated individuals. Although a definite link between chronically high BSLs and complications has been established, the link is not definitely causal - so some people can ‘get away with’ much higher BSLs than would be possible for others to do. The actual occurrence of complications can also frequently appear completely arbitrary, no matter how well-controlled the diabetic who suffers them.

Latest Research

At the time of writing, new research has just been published on pancreatic islet cell transplantation for insulin dependent diabetes.

The research reports on a new regimen for transplanting pancreatic islet cells from cadaveric donors (victims of road accidents etc, who are brain dead) using new immunosuppressants to decrease rejection of transplanted tissue. It was found that all of the seven people in the study remained free form the need for insulin injections (average follow up at the time of writing so far is 11 months). The main drawback is that each individual has had to have at least two transplants. The transplant procedure involved inserting a small catheter into one of the neck veins, passing it down and through the liver into the veins near the pancreas and injecting the islet cell preparation into the vessels around the pancreas. This can be done under light sedation and does not need a general anaesthetic.

Viagra blackmarket thriving

Viagra is easily available over the internet
The anti-impotence drug Viagra is being bought over the internet and then sold illegally at almost twice the price in pubs and clubs in London, a BBC investigation has revealed
There are hundreds of online sites where Viagra can be bought.
Although most require some form of online consultation, this is often cursory.
It is impossible to tell how much Viagra - and other prescription drugs - are coming into the country in this way.
There is also growing evidence that those who peddle illegal drugs in clubs are starting to deal in Viagra. Combined with the illegal drug Ecstasy it is well known on the club scene as Sexstasy.
Drug worker Mark McPherson, from Turning Point, said: “We are aware anecdotally of combinations of Viagra and Ecstasy being used on the club scene.”
One dealer told BBC’s Today Programme: “I go on the internet, type in the world Viagra, millions of sites pop up.
“You have got loads of options. It is well cheap, you pick up the tabs for Ј8 each, you can buy a maximum of 90 tabs, you fill in some little questionnaire and you can knock them out for Ј15 a tab, so the mark-up is good.”
Many people want to buy the pills, he said, from men in their early 20s to old age pensioners.
Some think they have a sexual problem, but others just take Viagra for recreational purposes.
Viagra manufacturer Pfizer warns that Viagra should not be taken unless it is recommended by a doctor.
In combination with nitrates used to treat heart conditions, it can prove fatal online pharmacy shipp international.
