Physical Therapists Can Help Relieve Pain

In light of proposed sterner warning labels for acetaminophen, aspirin, and ibuprofen by federal health officials, patients may wish to consider the benefits of physical therapist intervention for pain relief from certain conditions, according to the American Physical Therapy Association (APTA).

"Many people are looking for alternatives to the sole use of medication to deal with painful conditions," said APTA President R Scott Ward, PT, PhD. "Pain medication may help you get through periods of severe pain, but it won't always help you eliminate the underlying cause of some kinds of pain. For many individuals, it is the underlying causes such as poor posture and alignment, weak and/or inflexible muscles, or tight joint structures that actually exacerbate the painful condition," Ward explained. "A physical therapist will perform a complete musculoskeletal examination and design an individualized treatment program to reduce pain and improve function."

There are many types of pain and inflammation that can be reduced by physical therapist intervention. For example, chronic pain in the back, shoulder, or knee, or pain associated with certain degenerative diseases such as osteoarthritis, can be reduced with the appropriate combination of medication and exercise. "The physical therapist, in collaboration with the patient and the patient's physician, can help the patient manage his or her health over the long term," explained Ward.

For pain of a "mechanical" origin such as back, shoulder, or knee pain, physical therapist intervention may include therapeutic exercise, manual therapy, and functional training. "The goal of the physical therapist is to reduce pain, improve the ability to perform daily activities, and help the patient return to doing the things he or she likes to do," said Ward. "It is also true that patients may unknowingly contribute to their own pain, such as by exercising improperly or with poor posture, and physical therapists can identify and help to correct those behaviors." Ward added, "Through the use of home programs designed to fit the patient's needs, the physical therapist can efficiently progress the patient's rehabilitation and teach the patient how to prevent a recurrence of the original condition."

For osteoarthritis, a degenerative disease of the cartilage and bone, physical therapist intervention may include exercises for strength, flexibility, range of motion, and the use of devices designed to rest or support the joint, such as orthotics or splints.

Physical therapists, who treat nearly 1 million people every day, work with individuals to prevent the loss of mobility before it occurs by developing fitness- and wellness-oriented programs for healthier and more active lifestyles. Many insurance policies also cover post-rehabilitation gym programs. "Most people who desire a fitness plan are not athletes," Ward explained. "They are 'ordinary people' who exercise lightly to moderately. Many have a prior health condition, such as chronic low back pain, that can benefit greatly from physical therapist management focused on increasing muscle strength and endurance, restoring and improving range of motion in joints, increasing cardiovascular endurance, and decreasing muscle and joint pain." The physical therapist individualizes exercise programs based on functional limitations as a result of injury or illness.

Is Workers' Comp Fair? Research Finds No Link Between Cash Settlements, Future Impairment

People who receive higher disability ratings for work-related back injuries don't necessarily fare worse over the long term than those who get lower ratings, a Saint Louis University study finds.

The study, which reinforced previous research showing blacks receive less treatment for their back pain than whites, was published online this month in the Journal of Pain. The new research is among the first to examine the relationship between Workers' Compensation settlements for back pain and long-term functional outcomes.

"A disability rating is supposed to reflect the amount of impairment a person has at the time that a case is closed. The presumption is that levels of impairment are stable and related to day-to-day levels of function. I was shocked that the associations between disability rating and subsequent levels of function weren't stronger," said Raymond Tait, Ph.D., professor of psychiatry at Saint Louis University School of Medicine.

Disability ratings also differed between African-Americans and Caucasians. According to Tait, those differences probably reflected differences in treatment: whites were four times more likely to have surgery than blacks. Thos who had surgery received larger settlements for their injuries, Tait said.

"While surgery inflated disability ratings, there appeared not relationship between surgery outcomes and how a person did thereafter," he said.

Tait and colleague John Chibnall, Ph.D., also a professor of psychiatry at Saint Lois University, looked at about 1,500 Missouri workers - 580 African-Americans and 892 Caucasians - whose Workers' Compensation claims for lower back pain were settled between Jan. 1, 2001 and June 1, 2002.

Researchers interviewed the employees 21 months after their settlements about how they were doing. They asked questions about pain intensity, general physical and mental health and whether they currently were working.

Tait and Chibnall said that their findings "raise questions about both the validity and the fairness of the current disability determination program. Disability settlements are designed to give people money toward a fresh start. Those settlements do not appear to reflect the residual levels of disability that people actually experience."

First Look At Sickle Cell Disease Hospitalizations In 10 Years

The first federal analysis in a decade of sickle cell disease hospitalizations shows that admissions of adults remained stable from 1997 to 2004. In 2004, roughly 83,000 hospital stays were for adults and 30,000 were for children. Of the latter, 2,000 stays were for infants, according to the latest News and Numbers issued by the Agency for Healthcare Research and Quality.

Sickle cell disease, an inherited blood disease mostly affecting African Americans, causes red blood cells to lose their shape, block circulation and cause organ damage. The illness has no common cure and patients with periodic pain are often treated with pain medications.

The study found:

-- Patients spent about 5 days in the hospital, which cost facilities an average of $6,223 per stay. Total hospital costs were nearly $500 million overall in 2004

-- Medicaid paid for 65 percent of the stays of patients hospitalized primarily for sickle cell disease, Medicare paid 13 percent, private insurers were responsible for 15 percent, and 4 percent were uninsured.

-- The number of persons with sickle cell disease who died while hospitalized in 2004 was relatively low -- 699 adults and 47 children. In-hospital deaths for children remained low and constant from 1994 to 2004.

This News and Numbers is based on data in Sickle Cell Disease Patients in U.S. Hospitals, 2004, HCUP Statistical Brief # 21.В  The report uses statistics from the Nationwide Inpatient Sample, a database of hospital inpatient stays that is nationally representative of all short-term, non-federal hospitals. The data are drawn from hospitals that comprise 90 percent of all discharges in the United States and include all patients, regardless of insurance type as well as the uninsured.

Headaches Form Over A Possible New Form Of Aspirin

New scientific insights into the packaging of molecules in solids may tempt jokesters to add a second line to that old medical axiom, "Take two aspirin and call me in the morning." Insiders familiar with an unfolding controversy about aspirin -- more than 100 billion tablets of which are produced worldwide each year -- might quip, "Well, doctor, should I take Form I or Form II?"

An article schedule
d for the Jan.1 issue of Chemical & Engineering News, the ACS' weekly newsmagazine, discusses the controversy that has arisen since 2006, when scientists isolated, described and filed a patent for a putative new form of aspirin. Written by C&EN senior editor Ivan Amato, the article describes subtle differences in the crystal, or internal, structures of familiar acetylsalicylic acid and the newly described Form II of aspirin.

The article explains that the discovery of Form II may not have any practical implications for people who take aspirin. However, uncertainties about Form II do showcase surprising knowledge gaps in organic chemists' understanding of the solid state of matter, Amato writes. Those gaps are apparent at a time when pharmaceutical companies are recognizing that minuscule differences in the crystal structures of drugs can have big influences on how drugs work in patients.

Patients With PTSD Experience Less Pain Sensitivity -- May Be Related To Altered Processing

Patients with posttraumatic stress disorder show reduced pain sensitivity, a pattern that may be related to altered pain processing in the brain, according to a report in the January issue of the Archives of General Psychiatry, one of the JAMA/Archives journals.

Posttraumatic stress disorder (PTSD) is an anxiety disorder that may occur in individuals exposed to a traumatic event. It is characterized by chronic arousal, re-experience of the event, and avoidance of stimuli related to the event, according to background information in the article. To the authors' knowledge, no functional imaging study has explored whether patients with PTSD experience and process pain in a different way than control subjects.

Elbert Geuze, Ph.D., of Central Military Hospital and the Rudolph Magnus Institute of Neuroscience, Utrecht, the Netherlands, and colleagues conducted a study to examine neural correlates of pain processing in patients with PTSD. Twelve male Dutch veterans with PTSD and 12 male veterans without PTSD were recruited and matched for age, region of deployment and year of deployment. The experimental procedure consisted of psychophysical assessment and neuroimaging with functional magnetic resonance imaging (fMRI)--the use of magnetic resonance imaging to learn which regions of the brain are active in a specific function. During fMRI, the patients rated the pain they experienced from fixed and variable temperatures applied to their hands.

"Patients with PTSD rated temperatures in the fixed-temperature assessment as less painful compared with controls," the authors report.

"Before fMRI, patients with PTSD already showed a significant reduction in pain sensitivity," the authors write. "During imaging, patients with PTSD rated a fixed temperature as significantly less painful than control veterans." Patients with PTSD showed altered pain processing in brain areas associated with mood and cognitive pain processing.

"These data provide evidence for reduced pain sensitivity in PTSD. The witnessed neural activation pattern is proposed to be related to altered pain processing in patients with PTSD," the authors conclude.

Mayo Clinic Successfuly Separates Conjoined Baby Twins Abby And Maddy


Conjoined 5-month old twins, Abygail and Madysen Fitterer from North Dakota, have been successfully separated by surgeons at Minnesota's Mayo Clinic. Doctors say they are doing well.

The surgery took 6 hours and involved a large team of 40 surgeons and nursing staff, led by Christopher Moir, the lead surgeon.

Abygail and Madysen's parents, Stacy and Suzy Fitterer, of Bismarck, North Dakota, in a webcast news conference released earlier today, expressed their joy at the successful outcome and thanked the doctors and nurses and all their supporters. Also present was their two and half year old son, Nicholas.

Dr. Moir said that it had been a very emotional day, but that the operation had been "flawless" and "went exactly as we had hoped, and exactly as we had planned. Abby and Maddy are still together in our hearts, in our minds and in our spirits, and right now they are up in the ICU together working their hardest after a long but very successful operation".

Dr. Moir described the surgical challenges of the operation with the aid of life-sized models of the babies' ribcages and chest cavities. There were two sets of models: one set for before the separation and another set for afterwards. The models had been created by the Mayo clinic's department of engineering and their team of medical illustrators.

Using the life-sized models the surgical team was able to plan the surgery and the reconstruction in great detail in advance.

Much of the operation involved separating the chest and abdominal walls that were conjoined, and then the separation of the major organs. The hearts had to be repositioned and the chest walls reconstructed. Also, the babies shared one liver, but this could be divided because there were separate drainage systems.

As the baby girls were joined at the chest, their hospitalization had to start nearly 100 days earlier, in June 2006, when they were just 8 weeks old. This was when they had their first operation, it lasted 4 hours and involved placing chest expanders under the skin on their shared chest wall.

Over the following 3 months, the chest expanders caused the skin and muscle around the chest wall to stretch and regrow. If the skin and muscle is not stretched it is not possible to close the hole left after separation.

The operation to separate the twins started at 09.50 AM (CST), and they were placed on separate operating tables, ready for chest reconstruction at 12.27. The Mayo Clinic video shows the surgical team applauding as the girls are placed on the tables.

The Mayo Clinic has performed four previous separations of conjoined twins. According to their press release, conjoined twins can occur in one in 50,000 pregnancies, but they account for only 1 in 250,000 live births.

DURECT Starts Phase II Dosing For TRANSDUR(TM)-Bupivacaine (DUR-843)

DURECT Corporation (Nasdaq: DRRX) today announced that we have started Phase II dosing in the U.S. under an FDA-accepted Investigational New Drug (IND) application for TRANSDUR(TM)-Bupivacaine (DUR-843), a transdermal pain patch for patients suffering from Post-Herpetic Neuralgia (post-shingles pain or PHN).

DURECT's Phase I trial for TRANSDUR-Bupivacaine, initially reported on December 11, 2006, demonstrated good safety, tolerability and drug release for up to 3 days. TRANSDUR-Bupivacaine is intended to provide up to 3 days of pain relief for patients suffering from PHN, as compared to a wearing time limited to 12 hours with currently available patches.

"The initiation of the Phase II program for TRANSDUR-Bupivacaine is an important milestone for us," said James E. Brown, DURECT's President and CEO. "Based on our TRANSDUR technology, we believe that the product profile of TRANSDUR-Bupivacaine represents an improvement over existing pain control products for patients suffering from PHN."

DURECT's Phase II program for TRANSDUR-Bupivacaine has begun with a randomized, multi-center, double-blind, placebo controlled, two-way crossover trial in approximately 50 patients with PHN to assess safety as well as the magnitude, duration and characteristics of analgesic activity of TRANSDUR- Bupivacaine.

Bupivacaine, the active agent in TRANSDUR-Bupivacaine, is a potent, FDA- approved long-acting local anesthetic used in regional anesthesia including infiltration, nerve block, epidural and intrathecal anesthesia. Bupivacaine is a more potent sodium channel blocker and has a longer duration of action than lidocaine, the active ingredient for Lidoderm(R), the market leader for post- herpetic neuralgia pain management.

Victory Pharma, Inc. Announces Investigational New Drug MGX-006 Approved By The FDA

Victory Pharma, Inc. announced today the U.S. Food and Drug Administration (FDA) completed its review for the company's Investigational New Drug (IND) application to evaluate MGX-006, a unique formulation of a currently marketed agent with indications for various nausea and vomiting conditions. The MGX-006 program is being supported via a co-development agreement between Victory and its technology partner signed in August of 2006. Upon regulatory approval, Victory intends to market the product through its proprietary U.S. based sales organization.

"MGX-006 emerged from our strategy to develop and acquire products utilized for the treatment of pain or pain-related illness," said Dave Gonyer, Vice President of Commercial Development for Victory Pharma. "Many patients who experience pain also experience nausea due to the disease state itself or the treatments for it. We believe that MGX-006 could provide a significant improvement to the treatment of nausea and vomiting and substantially improve compliance to benefit patients."

The successful initiation of a second development program represents an important milestone in Victory's evolution into a leading pain and related specialty pharmaceutical company. The anti-nausea market remains an area of unmet medical need with expanding market potential. Many anti-emetics are used concomitantly with pain products, and are often prescribed by Victory's target audiences for its current product portfolio. MGX-006 is targeted to enter pivotal trials in 2007 in conjunction with a leading clinical research organization.

MRI Of The Ankle Changes Patient Treatment And Improves Referring Physician Confidence In Diagnosis

MR imaging can make a dramatic difference in the management of patients with ankle pain, changing treatment in about one-third of the patients, a new study finds.

The study, of 91 patients, found that MR changed the management plans of 35% of patients, said Philip W.P. Bearcroft, MD, of Cambridge University Hospitals in England. "This is itself is significant, but more significant is the fact that before an MRI was done, 65 of the 91 patients were scheduled to undergo surgery. After an MRI was done, nine of those patients were treated nonsurgically," Dr. Bearcroft said.

Dr. Bearcroft and his colleagues conducted the study in conjunction with an orthopedic foot and ankle surgeon at a regional teaching hospital. The surgeon noted his proposed treatment plan for each patient before and after an MR examination. The surgeon also noted the potential diagnoses for each injury. Before an MR examination was done, the surgeon indicated an average 2.3 possible diagnoses per patient. "After MRI was performed, the number of diagnoses per patient was reduced to 1.2," said Dr. Bearcroft. MRI increased the referring physician's confidence in his diagnoses, Dr. Bearcroft said. "In 66% of the MRI examinations performed, the referring surgeon felt that his understanding of the patient's disease had either depended upon or had been substantially improved by MRI," he added.

"This study is a bit different than the traditional radiological study," Dr. Bearcroft said. "Most studies relate to improving technique or look at the accuracy and predictive value of imaging techniques. This one was designed to determine if we really make a difference to the referring physician and the patient," he said.

The study appeared in a recent issue of the American Journal of Roentgenology, published by the American Roentgen Ray Society.

Horizon Therapeutics Announces Special Protocol Assessment With FDA For Phase 3 Trial Program

Horizon Therapeutics, Inc., a privately held biopharmaceutical company, today announced that it has reached agreement with the U.S. Food and Drug Administration (FDA) via a Special Protocol Assessment for the Phase 3 trial program of HZT-501, its "GI-friendly" prescription NSAID for mild-to-moderate pain relief.

The SPA agreement indicates that if the trials successfully meet their primary endpoint, the data will provide support for an efficacy claim in a marketing application to the FDA. The two trials are expected to begin patient enrollment in the first half of this year.

HZT-501 is a proprietary formulation of the world's most prescribed non-steroidal anti-inflammatory drug (NSAID) ibuprofen, combined with the most potent H2 receptor antagonist famotidine, in a single pill. HZT-501 is specifically designed to provide pain relief while reducing stomach acidity during the peak time of risk for ulceration. In a randomized pilot clinical study published in The New England Journal of Medicine (Taha, et. al May 1996), famotidine was demonstrated to significantly reduce the incidence of gastric and duodenal ulcers vs. placebo when administered with NSAIDs.

"While NSAID's provide excellent pain relief, they can cause serious gastrointestinal side effects such as ulcers," said Dr. Loren Laine, Keck School of Medicine of the University of Southern California. "This is an important medical issue, especially given data from studies that suggest that many patients at risk do not receive appropriate therapy. HZT-501 was designed with the specific goal of decreasing the GI injury associated with NSAID's."

Phase 3 Clinical Study

The Phase 3 program will comprise two trials involving a total of 1,200 patients with mild-to-moderate pain, including patients with osteoarthritis. Horizon Protocol HZ-CA-301 and HZ-CA-303 will evaluate the efficacy and safety of HZT-501 with a primary endpoint of reduction in the risk of development of ibuprofen-associated upper gastrointestinal ulcers in patients who require the use of ibuprofen.

The clinical trials will be multi-center, randomized, controlled, and blinded for up to 24 weeks of treatment, followed by a 4 week safety evaluation period. The studies will be conducted in the United States.

Horizon has successfully completed product development and early supportive clinical studies on HZT-501 necessary to begin Phase 3 trials including PK/PD formulation design, drug-drug interaction, and comparative bioavailability of HZT-501 to approved reference drug products.

"The SPA is a major milestone that solidifies what we believe is a clearly defined development and regulatory pathway to address this significant unmet medical need," said George F. Tidmarsh, M.D., Ph.D., co-founder and chief executive officer of Horizon Therapeutics. "In addition to HZT-501, we are building a pipeline of therapies through similar combinations of existing pharmaceutical products that offer the potential for rapid development and commercialization with relatively low risk."

Proof-of-concept

In the May 30, 1996 edition of the New England Journal of Medicine, an article, "Famotidine for the Prevention of Gastric and Duodenal Ulcers Caused by Non-steroidal Anti-inflammatory Drugs" was published by Taha, et. al. The study was a randomized, controlled trial including 285 arthritis patients. The primary endpoint was the measurement of the cumulative incidence of endoscopically diagnosed gastric and duodenal ulcers at 4, 12 and 24 weeks in patients treated with an NSAID alone vs. those treated with NSAID plus a total daily dose of either 40mg or 80mg of famotidine.

The cumulative incidence of gastric ulcers was 20% in the NSAID-alone group and 8% in the 40-mg BID (twice daily) famotidine plus NSAID group (p = 0.03). The cumulative incidence of duodenal ulcers was 13% in the NSAID-alone group and 2% in the 40-mg BID famotidine plus NSAID group (p = 0.01). There were also significantly lower rates of gastric and duodenal ulceration when analyzed separately and when combined (28% for the NSAID-alone group vs. 11% for the 40-mg BID famotidine plus NSAID group; p = 0.003).

About the Pain Market

HZT-501 targets the widespread product void in the mild-to-moderate pain market left by COX-2 inhibitors such as Vioxx(R), which have either been taken off the market or prescribed less frequently due to elevated cardiovascular risk. In 2005, the U.S. non-steroidal anti-inflammatory (NSAID) market grew over 20 percent to 73 million prescriptions. Over 26 million ibuprofen prescriptions are now written annually in the U.S. alone.

However, while commonly prescribed to treat pain, NSAIDs have been linked to serious gastrointestinal (GI) side effects in up to 25 percent of all chronic arthritis patients. NSAID-induced GI toxicity causes an estimated 16,000 deaths and more than 100,000 hospitalizations annually in the United States. Despite this, studies have shown that as low as 30% of high-risk patients are commonly co-prescribed a gastro-protective agent in combination with their NSAID to prevent or relieve side effects. In addition, patient adherence to a regimen of separate GI and pain medications has also been shown to be poor.

About Horizon Therapeutics

Horizon Therapeutics, Inc. is a late stage biopharmaceutical company focused on the rapid development and commercialization of therapeutic treatments for mild-to-moderate pain management. The Company is building a novel portfolio of therapies through innovative combinations of approved pharmaceutical products that seek to improve safety, efficacy, and patient compliance. Its lead product candidate, HZT-501, will enter Phase 3 trials in 2007. In addition to HZT-501, Horizon has a pipeline of follow-on pain combination products in earlier stages of development.
