FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with leg pain is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about leg pain, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to leg pain, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on leg pain. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to leg pain, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on leg pain. The Editors

CHAPTER 1. STUDIES ON LEG PAIN Overview In this chapter, we will show you how to locate peer-reviewed references and studies on leg pain.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and leg pain, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “leg pain” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
On-Again, Off-Again Leg Pain: What It Is and What to Do About It Source: Diabetes Self-Management. 12(3): 10-12, 14, 16. May-June 1995. Contact: Available from R.A. Rapaport Publishing, Inc. 150 West 22nd Street, New York, NY 10011. (800) 234-0923. Summary: This article describes intermittent claudication, a condition that causes cramping pains in the legs during exercise. Caused by peripheral vascular disease, this condition is more likely to occur in people with diabetes. Topics include the symptoms of intermittent claudication; diagnosis of the condition; common spots for obstructions caused by peripheral vascular disease; symptoms of peripheral vascular disease; diagnostic tests used to confirm peripheral vascular disease; risk factors, including cigarette smoking, hypertension, hyperlipidemia, obesity, and physical inactivity; the

effects of diabetes on peripheral vascular disease; and treatment options, including drug therapy, reducing risk factors, chelation therapy, balloon angioplasty, and bypass surgery. One sidebar lists typical symptoms associated with intermittent claudication and lists other disorders that can be easily confused with the condition. 1 figure. •
Exercise-Related Lower Leg Pain: An Overview Source: Medicine and Science in Sports and Exercise. 32(3 Supplement): S1-S3. March Supplement 2000. Summary: This journal article provides health professionals with information on the etiology and diagnosis of exercise related lower leg pain (ERLLP). The most common presentation of ERLLP, which is an extremely common complaint among athletes, is shin pain. Shin pain generally occurs in one or more of the following structures: bone, periosteum, and muscle compartment. Overuse may cause muscle compartments to become swollen and painful. Two common compartment syndromes seen in runners are deep posterior compartment syndrome and anterior compartment syndrome. One of the major causes of ERLLP is abnormal biomechanics. Other causes are neural and vascular. Diagnosis of ERLLP involves taking a good history, performing a physical examination, and conducting appropriate diagnostic tests. Compartment syndrome, particularly the anterior and deep posterior compartments of the lower leg, may mimic a stress fracture since it also presents with exercise related pain. Other conditions that mimic stress fracture include traction periostitis and medial tibial stress syndrome. Referred pain from the lumbar spine and vascular pathology should always be considered in the differential diagnosis of ERLLP. Tumor and infection are two bony pathologies that can mimic stress fracture. 2 figures and 2 tables.

Exercise-Related Lower Leg Pain: Vascular Source: Medicine and Science in Sports and Exercise. 32(3 Supplement): S34-S36. March Supplement 2000. Summary: This journal article uses two case studies to provide health professionals with information on the vascular aspects of exercise related lower leg pain. Although vascular pathology is rare in exercise related lower leg pain, it is an important cause of such pain in athletes. Both arterial entrapment and atherosclerotic vessel disease are causes of exercise induced leg pain. The first case study involved a 24 year old woman sprinter with a 1 year history of exercise related distal calf and Achilles pain. Noninvasive vascular tests revealed complete occlusion of the popliteal artery with forced active plantar flexion of the ankle. Magnetic resonance angiography confirmed the diagnosis of bilateral popliteal artery entrapment. Surgical removal of an abnormally large plantaris muscle significantly reduced the woman's symptoms and allowed her to return to competitive athletics. The second case study involved a 30 year old female triathlete who had presented earlier at the age of 23 with a history of exercise related right sided hamstring pain. She sought numerous treatments with no success. She continued to train and compete despite her symptoms for several years. Referral to a vascular surgeon who organized conventional angiography resulted in a finding of multiple endofibrotic lesions of the right external iliac artery. Treatment of the largest of the lesions with balloon catheter dilation resulted in improvement, but not resolution, of her symptoms. The article discusses both popliteal artery entrapment syndrome and endofibrotic disease in terms of their clinical presentation, diagnosis, and treatment. 13 references.

Federally Funded Research on Leg Pain The U.S. Government supports a variety of research studies relating to leg pain. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to leg pain. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore leg pain. The following is typical of the type of information found when searching the CRISP database for leg pain: •

Principal Investigator & Institution: Ouriel, Kenneth; Surgery; Cleveland Clinic Lerner Col/Med-Cwru Cleveland, Oh 44195 Timing: Fiscal Year 2003; Project Start 22-SEP-2003; Project End 31-AUG-2008 Summary: (provided by applicant): Peripheral arterial disease (PAD) is found in almost 20% of the population aged 55 and older. It is responsible for incapacitating symptoms of leg pain when walking, culminating in amputation in a small proportion of patients. Further, the presence of PAD is a strong marker for future cardiovascular events such as myocardial infarction and stroke. Despite the clinical significance of PAD, it is under diagnosed and its pathobiology remains ill defined. While imaging studies play an integral role in the study of most disease processes, angiography, standard ultrasound examination, and even magnetic resonance imaging do not provide adequate resolution of the arterial wall to quantify and characterize the extent of vascular wall abnormalities or to track changes over time. Intravascular ultrasound (IVUS) technology is associated with spatial resolution of 80-100 fm radially and 150-200 fm circumferentially. As such, IVUS appears ideally suited to the quantification of vascular wall changes. Our group has studied IVUS in the characterization of coronary artery plaque morphology, correlating clinical signs and symptoms with atheroma burden and content. We propose similar studies in the peripheral arterial bed, quantifying the amount and composition of lower extremity arterial atheroma and relating these findings to the patients' clinical presentation and subsequent course. This goal will be accomplished through the completion of three separate but concurrent studies: (1) Histologic sections of fresh arterial segments from cadaver limbs and amputation specimens will be correlated with IVUS-derived radiofrequency data to quantify arterial plaque burden and composition (calcium, collagen, fibro-lipidic and necrotic components). (2) Patients undergoing standard lower extremity angiography for PAD will be studied with IVUS at the same sitting. IVUS findings will be correlated with demographic factors (age, gender, race) and symptom severity (claudication, rest pain, tissue loss). Patients will be followed for 2

up to five years, and the occurrence of ischemic events (worsening of leg ischemia, need for intervention and re-intervention, and distant complications such as Mi and stroke) will be reconciled with the arterial wall content at the baseline examination. (3) A randomized, blinded clinical trial of high-dose atorvastatin vs. placebo will be performed in patients with intermittent claudication, based on our hypothesis that statin therapy will result in stabilization or regression of femoral artery plaque, differences best assessed with high resolution imaging studies. IVUS data will be collected at baseline and at 24 months. The primary endpoint will be the change in femoral arterial plaque volume; baseline arterial wall parameters will be assessed in the subgroup of stain responders vs. non-responders. The completion of these three investigations should yield a validated, high resolution, real time imaging study with which to assess risk and base treatment decisions in patients with PAD.

Project Title: DIRECT NEUROTOXICITY OF LOCAL ANESTHETICS Principal Investigator & Institution: Johnson, Michael E.; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2003 Summary: The objective of this proposal is to determine the mechanism of direct neurotoxicity of spinal (intrathecal) lidocaine. Other local anesthetics have a risk of persistent lumbosacral neurotoxicity of approximately 1 in 10,000. Lidocaine at doses producing surgical anesthesia has an increased risk of approximately 1 in 200 via continuous spinal anesthesia, and approximately 1 in 1300 via single injection spinal anesthesia. Transient neurologic symptoms (TNS) of buttock and leg pain occur in 16-40 percent of patients receiving spinal lidocaine in multiple large studies. Lidocaine is also neurotoxic in an animal model that produces lower extremity anesthesia with 5 percent lidocaine, and in cell culture and in vitro nerve studies. To address the mechanism of this neurotoxicity, most studies will be conducted at the level of the single cell, using digitized video fluorescence microscopy, phase microscopy, and flow cytometry, with appropriate, specific, fluorescent probes. Immunoblotting and fluorogenic assays of fractionated cell lysates will also be utilized. The ND7 cell line, derived from rat dorsal root ganglion, will be used as a model system for neuronal injury. Two hypotheses will be tested as specific aims: (1) Lidocaine interferes with multiple mechanisms for maintaining normal cytoplasmic calcium (Ca2+cyt), causing an increase to toxic levels. Preliminary data show a marked effect of lidocaine to elevate Ca2+cyt (5-7 fold with 5 percent lidocaine; greater than 15 percent cell death within 60 min). The effect of lidocaine on possible mechanisms of Ca2+cyt elevation will be tested, including influx from extracellular buffer, release from endoplasmic reticulum, and release from mitochondria. The causal relationship of lidocaine-induced Ca2+cyt elevation to neurite injury, plasma membrane blebbing, and neuronal death by necrosis and apoptosis will be determined. (2) Lidocaine activates multiple mechanisms of mitochondrial injury. Preliminary data show a marked effect of lidocaine to decrease mitochondrial membrane potential deltapsi in whole cells. Potential mechanisms of decreased deltapsi by lidocaine will be tested: protonophoric mitochondrial uncoupling, inhibition of mitochondrial respiration, and induction of the mitochondrial permeability transition. The effect of lidocaine will also be tested on mitochondrially based mechanisms of cell death: release of mitochondrial cytochrome c, and caspase activation. The Ca2+cyt dependence of each mechanism of mitochondrial injury will be determined by experiments with and without Ca2+cyt clamped at a normal level.

Project Title: DOSE RESPONSE EVALUATION OF ILOPROST IN TREATMENT OF CLAUDICATION Principal Investigator & Institution: Porter, John M.; Oregon Health & Science University Portland, or 972393098 Timing: Fiscal Year 2001 Summary: The primary purpose of this study is to evaluate the effectiveness and safety of the drug iloprost while evaluating the dose response characteristics of iloprost in patients diagnosed with claudication (leg pain) secondary to PAOD. This difficulty is called peripheral arterial occlusive disease (PAOD) and is due to lack of adequate blood flow to the legs due to partially or completely blocked arteries.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.3 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with leg pain, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “leg pain” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for leg pain (hyperlinks lead to article summaries): •

CHAPTER 2. NUTRITION AND LEG PAIN Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and leg pain.
Finding Nutrition Studies on Leg Pain The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.4 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “leg pain” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. PATENTS ON LEG PAIN Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.6 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “leg pain” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on leg pain, we have not necessarily excluded non-medical patents in this bibliography.
Patent Applications on Leg Pain As of December 2000, U.S. patent applications are open to public viewing.7 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to leg pain:

Novel early intervention spinal treatment methods and devices for use therein Inventor(s): Pellegrino, Richard C.; (Mendon, MA), Reynolds, Martin; (Mansfield, MA) Correspondence: Audley A. Ciamporcero JR.; Johnson & Johnson; One Johnson & Johnson Plaza; New Brunswick; NJ; 08933-7003; US Patent Application Number: 20030181963 Date filed: March 21, 2002 Abstract: There is provided a device for therapeutically treating back or leg pain, comprising:a) a probe having a proximal portion and a distal portion,b) first and second treatment sources, each source located in the distal portion of the probe,wherein the first treatment source is adapted to therapeutically treat a first tissue site, the second treatment source is adapted to therapeutically treat a second different tissue site, andwherein the first and second different tissue sites are selected from the group consisting of:i) a first intervertebral disc,ii) a first vertebra,iii) a first spinal ligament, andiv) a first spinal facet joint capsule,v) a second intervertebral disc,vi) a second vertebra,vii) a second spinal ligament, andviii) a second spinal facet joint capsule. Excerpt(s): One of the leading causes of spine-related pain is the rupture or degeneration of discs located between lumbar vertebrae ("lumbar intervertebral discs"). Pain in the lower extremities may be caused by compression of spinal nerve roots by such damaged discs, while low back pain may be caused by collapse of these discs and by the adverse effects of bearing weight through a damaged, unstable vertebral joint. One conventional method of managing this problem is to treat the problematic intervertebral disc with energy. In some instances, the disc is globally heated. U.S. Pat. No. 5,433,739 ("Sluitjer I") proposes inserting an RF electrode or other heating electrode into the intervertebral disc and globally heating the entire intervertebral disc to a temperature significantly above body temperature. See col. 2, lines 52-56. Sluijter I teaches that this process can denervate the neural structures within the disc on a global or semi-global basis, thus relieving the patient of back pain related to stress of the disc and its surface. See col. 5, line 65-col. 6, line 2. Sluijter I further notes that the precise anatomical mechanism of this pain relieving process has not been totally clarified, and discloses not only that anatomical material changes within the disc material itself and the resulting volumetric changes may play some role, but also that the spread of heat to large neural structures in the proximity of the disc may be additional contributory factors of significance. See col. 13, lines 28-37. In some instances, only the nucleus of the disc is treated. For example, Choy et al., Spine, 17:8 (1992), pp. 949-956, discloses using a laser to evaporate the nucleus pulposus. It is believed that evaporation of the nucleus reduces the pressure within the disc, thereby relieving the pressure upon the nerves therein.

Restraint and exercise device Inventor(s): Hoffman, Jonathan; (Sunnyvale, CA) Correspondence: Morgan Lewis & Bockius Llp; 1111 Pennsylvania Avenue NW; Washington; DC; 20004; US Patent Application Number: 20020183177 Date filed: May 31, 2002
Patents 41
Abstract: A restraint and exercise device is provided to treat acute or chronic mechanical pain, particularly lumbopelvic and/or leg pain, and to restore and/or increase range of motion in suitable users. The device is particularly useful during exercise. The device may contain a restraint, such as two straps, connected to a support structure. The straps help restrain a portion of a person's body such as the pelvic region. The portion of the person's body may be restrained in a substantially pain-free position so as to reduce the pain that would otherwise be felt during exercise. Excerpt(s): This invention generally relates to a restraint device. Various implementations of the invention are envisioned, including its use as a lumbopelvic restraint device during exercise to relieve pain and/or restore range of motion in lower back, pelvis, and leg pain suffers or in healthy persons who wish to restore or increase their range of motion. It may also be used to treat pain and/or restore or increase range of motion in the neck, shoulders, upper back, middle back and other body parts. In the human anatomy, the lower spine, known as the lumbar spine, is joined to the pelvic bone at a joint known as the sacro-iliac joint. The sacro-iliac joint is a relatively stiff or rigid joint. The upper leg bone, known as the femur, is joined to the pelvic bone at the hip joint by means of hip ligaments. Only a limited degree of movement of the lumbar spine relative to the pelvis is possible at the sacro-iliac joint, due to the relatively stiff or rigid nature of this joint. Thus, in general, upon movement of the lumbar spine in any direction, at least some of this movement is translated into a movement of the pelvis at the hip joint. This is because the hip joint is relatively free-moving in comparison to the stiff sacro-iliac joint. Upon movement of the leg, at least some of the hip ligaments start to wind up. When these hip ligaments are fully wound up, further movement of the leg is translated into a movement of the pelvis. A major and longstanding health problem that spans the world is acute or chronic back pain. A countless number of people suffer from pain in the lumbopelvic region including their lower back and hip. The causes of back pain are too numerous to enumerate, but include injuries, bad posture, accidents, genetic defects, disease, and aging. For some, the pain arises only during exercise. As a result, many eliminate beneficial exercises from their routines. For others, hip and/or lower back pain is always present. Exercise may be a desirable or a necessary treatment for the pain for many of these people. But again, the very exercises needed to alleviate the pain are difficult to perform due to the increased pain during exercise. These people often become stuck in a depressing cycle of increasing pain as the exercises and treatments needed to alleviate pain are too painful to perform, with the lack of proper exercise resulting in weakening of the muscles and increased pain and/or discomfort. The amount of money and effort spent on trying to cure back problems and/or alleviate the pain and/or discomfort is staggering. Modem medical attempts to address these issues, including drugs, surgery, traction, manual mobilization and exercise, are costly and have met with little success. There is no doubt there is a longstanding need for a safe, reliable and cost effective way to solve the problems associated with lumbopelvic back pain and disorders. Also, there is no doubt that the numerous attempts by others to meet this need and solve these problems have largely been failures. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Summary: This chapter on symptoms of disorders of the genitourinary tract is from a textbook that offers a practical and concise guide to the understanding, diagnosis, and treatment of urologic diseases. The author notes that in the workup of any patient, the history is of paramount importance; this is particularly true in urology. The author discusses only those urologic symptoms that are apt to be brought to the physician's attention by the patient. It is important to know not only whether the disease is acute or chronic, but also whether it is recurrent, since recurring symptoms may represent acute exacerbations (worsening) of chronic disease. The author covers systemic manifestations, local and referred pain, kidney pain, pseudorenal pain (radiculitis), ureteral pain, vesical pain, prostatic pain, testicular pain, epididymal pain, back and leg pain, gastrointestinal symptoms of urologic diseases, symptoms related to the act of urination, frequency, nocturia (getting up at night to urinate), urgency, dysuria (painful urination), enuresis (bedwetting), symptoms of bladder outlet obstruction, urinary incontinence (involuntary loss of urine), oliguria (reduction of amount of urine), anuria (no urination), pneumaturia (gas in the urine), cloudy urine, chyluria (lymphatic fluid in the urine), bloody urine (hematuria), urethral discharge in men, skin lesions of the external genitalia, visible or palpable masses, edema (fluid accumulation), bloody ejaculation, gynecomastia (enlarged breasts), size of penis, infertility, and complaints related to sexual problems.

PRICE: $69.95 plus shipping and handling. ISBN: 0912423293. Summary: This section of a chapter on pediatric rheumatic diseases provides health professionals with information on pain syndromes. All children experience pain except those with congenital indifference to it. Although most pain is of short duration and due to noxious stimuli, chronic or recurrent musculoskeletal pain can be caused by inflammation, trauma, or psychological distress. There are various presentations of childhood chronic musculoskeletal pain, including generalized and localized hypermobility, growing pains, and amplified musculoskeletal pain syndromes. Hypermobility syndrome, which usually occurs in children aged 3 to 10, is characterized by intermittent nocturnal leg pain. Although reassurance is the main treatment for hypermobility, supportive footwear and an evening dose of acetaminophen or a nonsteroidal antiinflammatory drug may be helpful. The most common areas affected by hypermobility are the pes planus, genu recurvatum, and patella. Hypermobility is treated with exercise, orthotics, and, sometimes, surgery. There are various pain amplification syndromes affecting children. These syndromes are on a continuum and frequently overlap. The etiology of amplified musculoskeletal pain in children is unknown. Some possible causes include injury, illness, and psychological distress. Factors such as age, gender, hormones, and genetics may have a role. Diagnosis is based on medical history and a physical examination. A common form of treatment for any of the pain amplification syndromes is aggressive exercise therapy. Psychotherapy may also benefit many children. Musculoskeletal pain in children may be a manifestation of other diseases, including malignancies that affect the bones or bone marrow, endocrine disorders, and genetic disorders of collagen metabolism. 4 tables and 26 references.

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for leg pain. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with leg pain. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The
52
Leg Pain
following drugs have been mentioned in the Pharmacopeia and other sources as being potentially applicable to leg pain: Cilostazol •
Systemic - U.S. Brands: Pletal http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/500026.html
Pentoxifylline •
Systemic - U.S. Brands: Trental http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202450.html
Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists17 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.18 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.19 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
17 Adapted 18
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 19 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
61
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on leg pain can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to leg pain. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to leg pain. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “leg pain”:

Other guides Hip Injuries and Disorders http://www.nlm.nih.gov/medlineplus/hipinjuriesanddisorders.html Knee Injuries and Disorders http://www.nlm.nih.gov/medlineplus/kneeinjuriesanddisorders.html Leg Injuries and Disorders http://www.nlm.nih.gov/medlineplus/leginjuriesanddisorders.html Spinal Stenosis http://www.nlm.nih.gov/medlineplus/spinalstenosis.html
You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on leg pain. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: •
Lumbar Spinal Canal Stenosis: A Common Guide of Back and Leg Pain Source: American Academy of Family Physicians. March 2003. 2 p. Contact: Available online from American Academy of Family Physicians. Website: http://familydoctor.org. Summary: This fact sheet provides patients with information about lumbar spine canal stenosis, a condition characterized by a narrowing of the space in the lower spine that carries nerves to the legs. Symptoms include constant back and leg pain, numbness, and weakness. Neural claudication is often associated with lumbar canal stenosis. The symptoms of neural leg claudication are cramping, tiredness, or weakness that gets worse with activity. Treatment options for lumbar spine canal stenosis include exercise, physical therapy, anti-inflammatory drugs, and surgery. Healthfinder™
Healthfinder™ is sponsored by the U.S. Department of Health and Human Services and offers links to hundreds of other sites that contain healthcare information. This Web site is located at http://www.healthfinder.gov. Again, keyword searches can be used to find guidelines. The following was recently found in this database:

Source: American Academy of Family Physicians http://www.healthfinder.gov/scripts/recordpass.asp?RecordType=0&RecordID=6247 The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to leg pain. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to leg pain. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with leg pain. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about leg pain. For more information, see the
64
Leg Pain
NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “leg pain” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “leg pain”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “leg pain” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “leg pain” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.20
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions.

Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Acetaminophen: Analgesic antipyretic derivative of acetanilide. It has weak antiinflammatory properties and is used as a common analgesic, but may cause liver, blood cell, and kidney damage. [NIH] Adaptability: Ability to develop some form of tolerance to conditions extremely different from those under which a living organism evolved. [NIH] Adverse Effect: An unwanted side effect of treatment. [NIH] Aerobic: In biochemistry, reactions that need oxygen to happen or happen when oxygen is present. [NIH] Afferent: Concerned with the transmission of neural impulse toward the central part of the nervous system. [NIH] Agar: A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis. [NIH]
Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task. [NIH] Alkaline: Having the reactions of an alkali. [EU] Alkaloid: A member of a large group of chemicals that are made by plants and have nitrogen in them. Some alkaloids have been shown to work against cancer. [NIH] Alternative medicine: Practices not generally recognized by the medical community as standard or conventional medical approaches and used instead of standard treatments. Alternative medicine includes the taking of dietary supplements, megadose vitamins, and herbal preparations; the drinking of special teas; and practices such as massage therapy, magnet therapy, spiritual healing, and meditation. [NIH] Amplification: The production of additional copies of a chromosomal DNA sequence, found as either intrachromosomal or extrachromosomal DNA. [NIH] Amputation: Surgery to remove part or all of a limb or appendage. [NIH] Anaesthesia: Loss of feeling or sensation. Although the term is used for loss of tactile sensibility, or of any of the other senses, it is applied especially to loss of the sensation of pain, as it is induced to permit performance of surgery or other painful procedures. [EU] Analgesic: An agent that alleviates pain without causing loss of consciousness. [EU] Analog: In chemistry, a substance that is similar, but not identical, to another. [NIH] Anatomical: Pertaining to anatomy, or to the structure of the organism. [EU] Anesthesia: A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance
76
Leg Pain
of surgery or other painful procedures. [NIH] Anesthetics: Agents that are capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general anesthesia, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site. [NIH] Angiography: Radiography of blood vessels after injection of a contrast medium. [NIH] Angioplasty: Endovascular reconstruction of an artery, which may include the removal of atheromatous plaque and/or the endothelial lining as well as simple dilatation. These are procedures performed by catheterization. When reconstruction of an artery is performed surgically, it is called endarterectomy. [NIH] Animal model: An animal with a disease either the same as or like a disease in humans. Animal models are used to study the development and progression of diseases and to test new treatments before they are given to humans. Animals with transplanted human cancers or other tissues are called xenograft models. [NIH] Ankle: That part of the lower limb directly above the foot. [NIH] Anterior Compartment Syndrome: Rapid swelling, increased tension, pain, and ischemic necrosis of the muscles of the anterior tibial compartment of the leg, often following excessive exertion. [NIH] Antibody: A type of protein made by certain white blood cells in response to a foreign substance (antigen). Each antibody can bind to only a specific antigen. The purpose of this binding is to help destroy the antigen. Antibodies can work in several ways, depending on the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen. [NIH] Antigen: Any substance which is capable, under appropriate conditions, of inducing a specific immune response and of reacting with the products of that response, that is, with specific antibody or specifically sensitized T-lymphocytes, or both.

Abbreviated Ag. [EU] Anti-inflammatory: Having to do with reducing inflammation. [NIH] Antipyretic: An agent that relieves or reduces fever. Called also antifebrile, antithermic and febrifuge. [EU] Anuria: Inability to form or excrete urine. [NIH] Aorta: The main trunk of the systemic arteries. [NIH] Aortic Aneurysm: Aneurysm of the aorta. [NIH] Aponeurosis: Tendinous expansion consisting of a fibrous or membranous sheath which serves as a fascia to enclose or bind a group of muscles. [NIH] Apoptosis: One of the two mechanisms by which cell death occurs (the other being the pathological process of necrosis). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA (DNA fragmentation) at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth. [NIH]

[NIH] Complement: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names.
Dictionary 81
Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
