Patients eventually diagnosed as having the fibromyalgia syndrome often have symptoms which suggest alternate diagnoses such as peripheral neuropathy, spondylitis, metabolic myopathy, polymyalgia, early rheumatoid arthritis, early systemic lupus erythematosus or a chronic fatigue syndrome. Delay in diagnosis of fibromyalgia often proves costly and frustrating to the patient and may lead to inappropriate therapy.

Recent reports have not emphasized the presence of paresthesias in fibromyalgia syndrome. In our retrospective review of 161 patients with fibromyalgia we found that 84% complained of numbness or tingling at initial evaluation. Most had either bilateral upper and lower extremity or bilateral upper extremity paresthesias. None had concurrent diseases commonly associated with peripheral neuropathy. Thirty-six patients with paresthesias had electromyograms performed before the diagnosis of fibromyalgia and 32 were normal. At a second assessment performed at a mean of 25 months from time of diagnosis, 56 of these 57 patients reported current paresthesias. Paresthesias are common in fibromyalgia and may mimic a neurologic disorder, although objective abnormalities are rare. Judicious use of neurodiagnostic tests are therefore indicated in the clinical setting of fibromyalgia.

Pain is prevalent and undertreated in nursing home residents, despite the existing wide array of effective pharmacological and nonpharmacological treatment modalities. In order to improve the quality of life of these vulnerable individuals, practitioners require education about the correct approach to assessment and management. Assessment should be comprehensive, taking into account the basic underlying pathology (e.g. osteoarthritis, osteoporosis, peripheral neuropathy, fibromyalgia, cancer) as well as other contributory pathology (e.g. muscle spasm, myofascial pain) and modifying comorbidities (e.g. depression, anxiety, fear, sleep disturbance). Pharmacological management should be guided by a stepped-care approach, modelled after that recommended by the World Health Organization for treatment of cancer pain. Nonopioid and opioid analgesics are the cornerstone of pharmacological pain management. Tricyclic antidepressants and anticonvulsants can be very effective for the treatment of certain types of neuropathic pain. In addition to treating the pain per se, attention should be given to prevention of disease progression and exacerbation, as maintaining function is of prime importance. Nursing home residents with severe dementia challenge the practitioner's pain assessment skills; an empirical approach to treatment may sometimes be warranted. The success of treatment should be measured by improvement in pain intensity as well as physical, psychosocial and cognitive function. Effective pain management may impact any or all of these functional domains and, therefore, substantially improve the nursing home resident's quality of life.

Drugs that inhibit reuptake of monoamines are frequently used to treat pain syndromes, e.g. neuropathy or fibromyalgia, where mechanical allodynia is present. Several lines of evidence suggest the involvement of supraspinal sites of action of these drugs. However, a direct study of supraspinal serotonin (5-HT) or norepinephrine (NE) release in an animal model in which allodynia is expressed, e.g. neuropathy, has not been done. The ventrobasal (VB) thalamus and the hypothalamus are major supraspinal projection regions for spinal neurons that transmit nociceptive information and are innervated by monoaminergic fibers. This study determined if peripheral neuropathy would induce changes in extracellular monoamines in VB thalamus and hypothalamus. Male Sprague-Dawley rats had spinal nerve roots L5 and L6 tightly ligated (neuropathic rats; NP) or sham (SHAM) surgery; contralateral and ipsilateral VB thalamus and contralateral hypothalamus were dialyzed with modified artificial cerebral spinal fluid (aCSF), with and without fluoxetine. NP rats had significantly decreased 5-HT content in dialysates of the contralateral VB thalamus compared with SHAM rats with (82% decrease) or without (63% decrease) fluoxetine in the perfusion medium over the 180 min of the study. There were no differences in the ipsilateral VB thalamus. In contrast, release of 5-HT was unchanged in the hypothalamic dialysates of SHAM vs. NP rats. NE release was not different in dialysates of either the VB thalamus or hypothalamus of SHAM vs. NP rats. Synthesis of 5-HT, as assessed by accumulation of 5-hydroxytrytophan after treatment with an L-amino acid decarboxylase inhibitor, was not different between NP and SHAM rats in VB thalamic and hypothalamic brain tissue. This study is the first to demonstrate changes in monoamine release supraspinally in NP rats. The differential effect between VB thalamus and hypothalamus suggests that a terminal field change may be involved. Putative mechanisms for mediating this change include alterations of GABA-ergic systems and/or plasticity related to alterations in N-methyl-D-aspartate receptor activation and nitric oxide release related to afferent hyperactivity induced by neuropathic pain.

The fibromyalgia syndrome (FM) seems an unlikely candidate for classification as a neuropathic pain. The disorder is diagnosed based on a compatible history and the presence of multiple areas of musculoskeletal tenderness. A consistent pathology in either the peripheral or central nervous system (CNS) has not been demonstrated in patients with FM, and they are not at higher risk for diseases of the CNS such as multiple sclerosis or of the peripheral nervous system such as peripheral neuropathy. A large proportion of FM sufferers have accompanying symptoms and signs of uncertain etiology, such as chronic fatigue, sleep disturbance, and bowel/bladder irritability. With the exception of migraine headaches and possibly irritable bowel syndrome, the accompanying disorders are clearly not neurological in origin. The impetus to classify the FM as a neuropathic pain comes from multiple lines of research suggesting widespread pain and tenderness are associated with chronic sensitization of the CNS. An examination of how the term neuropathic pain is defined reveals a conceptual split into 2 partially overlapping groups of disorders: those with demonstrable pathology in the nervous system and those characterized primarily by enduring dysfunction in the nervous system. Requiring demonstrable pathology in the nervous system in the definition of neuropathic pain is the traditional approach. The expansion of the definition to require only enduring nervous system dysfunction is less palatable because it opens the classification to many disorders of uncertain etiology, including complex regional pain syndrome. As it is uncertain which of the many different chronic pain syndromes include an enduring component of central sensitization, restricting the term "neuropathic pain" to those disorders with a primary etiology clearly related to the peripheral or CNS is prudent and consistent with clinical practice.

Lyme disease is a tick-borne multisystem disease. It was first described in Lyme, Connecticut, USA in 1975. Cases have been reported in Canada, Switzerland, Austria, Australia and Great Britain. It is an inflammatory disease that has varied clinical manifestations ranging from skin rash (erythema migrans), arthritis, fibromyalgia, and regional lymphadenopathy, cardiac conduction defects to neurological manifestations of meningoencephalitis, Bell's palsy, peripheral neuropathy, and painful radiculoneuropathy. There has been no case record of Lyme disease in Kenya and indeed literature on Lyme disease in Africa is very scanty. We present two cases of Lyme disease with predominant neurological manifestations; outline their clinical presentation and management.

Chronic pain plagues older adults more than any other age group; thus, practitioners must be able to approach this problem with confidence and skill. This article reviews the assessment and treatment of the most common chronic nonmalignant pain conditions that affect older adults--myofascial pain, generalized osteoarthritis, chronic low back pain (CLBP), fibromyalgia syndrome, and peripheral neuropathy. Specific topics include essential components of the physical examination; how and when to use basic and advanced imaging in older adults with CLBP; a stepped care approach to treating older adults with generalized osteoarthritis and CLBP, including noninvasive and invasive management techniques; how to diagnose and treat myofascial pain; strategies to identify the older adult with fibromyalgia syndrome and avoid unnecessary "diagnostic" testing; pharmacological treatment for the older adult with peripheral neuropathy; identification and treatment of other factors such as dementia and depression that may significantly influence response to pain treatment; and when to refer the patient to a pain specialist. While common, chronic pain is not a normal part of aging, and it should be treated with an emphasis on improved physical function and quality of life.

An association between the hepatitis C virus (HCV) and various pain diagnoses, including arthritis, fibromyalgia, and peripheral neuropathy, has been reported. In this article, we review the literature on the relationship between HCV and pain, highlighting current knowledge as well as methodological issues that exist in many studies. We also present preliminary findings from a survey conducted at two Department of Veterans Affairs facilities to assess the scope and impact of pain on functioning in veterans with HCV. Our results indicate that pain is very prevalent within this population and that HCV-positive veterans who experience persistent pain have significant depressive symptoms and engage in high-risk behaviors, such as cigarette smoking and alcohol use. Finally, we draw upon our review and preliminary results to propose areas of future rehabilitative research and to address the implications for clinicians working with patients with comorbid HCV and pain.

Chronic, neuropathic pain may be secondary to myriad etiologies including diabetic peripheral neuropathy and fibromyalgia. It is a debilitating condition that imposes a significant burden on individuals and society alike. This article will review various instruments designed to assess quality of life (QoL) and key data assessing QoL of patients suffering from these diseases as well as currently available pharmacologic agents for symptomatic management. As basic and clinical science progress over the next few years, along with the introduction of novel pharmacologic agents, we anticipate greater potential for pain intervention and improvement in the quality of life of our patients.

Synthesized in 1990 as an anticonvulsant agent, pregabalin was designed as a lipophilic gamma-aminobutyric acid (GABA) analog substituted at the 3'-position in order to facilitate diffusion across the blood-brain barrier. It is an alpha2delta1 ligand that binds to, and modulates, voltage-gated calcium channels. This modulation is characterized by a reduction of the excessive neurotransmitter release that is observed in certain neurologic and psychotic disorders. Pregabalin has analgetic, anticonvulsant, and anxiolytic activity and has demonstrated efficacy in the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, and as adjuvant therapy for adult patients with partial onset seizures. Pregabalin was significantly more effective than placebo for the treatment of generalized anxiety disorder as well as of fibromyalgia and was well tolerated by most of the patients.
