Brandon Maggen Podiatric Medicine Burning Feet and "Pins & Needles What causes burning feet and "pins & needles"? The most common causes of a sensation of burning in the foot are mechanical friction or pressure against the skin inside footwear, or from compression or degeneration of nerves in the foot. Burning feet may also arise from wearing footwear that has inadequate ventilation for the skin surface. Compression of peripheral nerves in the foot is seen in tarsal tunnel syndrome, as well as in diseases such as hypothyroidism, diabetes and rheumatoid arthritis. Nerve entrapment of the sciatic nerve as well as malformation of arteries and veins in the spine can also cause burning feet. Burning feet may be due to nutritional causes, most commonly a lack of riboflavine, nicotinic acid, thiamine and pyridoxine (due to either a lack of vitamin B in the diet, or malabsorption, or chronic alcoholism or even in patients on chronic hemodialysis). It may be due to the development of peripheral nerve damage in diabetes or nerve dysfunction in hypothyroidism, or due to hereditary sensory neuropathy, known medically as autosomal dominant burning feet. Burning feet syndrome may be related to other disorders such as erythromelalgia, collagen vascular disorders, polycythemia vera, thrombocytosis, leishmaniasis (transmitted by biting sand flies), Gitelman syndrome (a rare renal tubular disorder), some states of carnitine deficiency as well as in multiple sclerosis. Recent spider bites on the lower limb can result in a burning feet sensation for a period of time until the body clears itself of the toxin and metabolites. What should I know about footwear to prevent burning feet and "pins & needles"? Avoid ill-fitting shoes that may compress or pinch nerves in the foot. Pinched nerves may result in the sensation of feet burning. Avoid the use of footwear that promotes perspiration. If pain is due to callus, remember that pressure or friction is the cause of callus. Avoid clogs, mules, very low-cut shoes or sandals, and thin-soled shoes if you are prone to callus buildup. Choose styles that do not require friction from the toes, such as those that grip around the heel (either closed heel or strap) plus a fastening or closure across the instep of the foot. Shoes with heels tilt body weight on to the ball of the foot, causing overload on the metatarsal joints under the ball of the foot. Women should choose lower heels for everyday use and reserve high heels for short one to two-hour functions or events. Teenage girls should not wear heels as their feet are still developing. What can I do about burning feet, and "pins & needles"? Find and eliminate the cause. Replace poor fitting shoes with anatomically correct, well-balanced and cushioned shoes. Avoid the use of high-heeled shoes for general daily wear. Remove the buildup of hard skin (such as that caused by walking barefoot outdoors) by means of daily light abrasion (using a pumice stone or fine grit foot file) together with regular daily use of a heel balm containing urea. Use temporary ball of the foot or metatarsal cushions to relieve pressure until such time as you can consult a podiatrist. Never use any form of chemicals or metal objects (including skin "graters") or blades to remove callus. Your best efforts will result in an uneven surface - that alone will stimulate formation of more callus by creating micro-overload areas. You may risk self-injury and infection. All thick callus is best treated by a podiatrist.

Always consult a podiatrist for pain in the foot, especially a sensation of burning feet. Your medical history and appropriate examinations will be needed to accurately diagnose the cause of the pain. Tel: 021 555 0396 www.sorefeet.co.za Email: [email protected] .

Merkies, MD, PhD1,7 Objective: Small nerve fiber neuropathy (SFN) often occurs without apparent cause, but no systematic genetic studies have been performed in patients with idiopathic SFN (I-SFN). We sought to identify a genetic basis for I-SFN by screening patients with biopsy-confirmed idiopathic SFN for mutations in the SCN9A gene, encoding voltage- gated sodium channel NaV1.7, which is preferentially expressed in small diameter peripheral axons. Methods: Patients referred with possible I-SFN, who met the criteria of 2 SFN-related symptoms, normal strength, tendon reflexes, vibration sense, and nerve conduction studies, and reduced intraepidermal nerve fiber density (IENFD) plus abnormal quantitative sensory testing (QST) and no underlying etiology for SFN, were assessed clinically and by screening of SCN9A for mutations and functional analyses. Results: Twenty-eight patients who met stringent criteria for I-SFN including abnormal IENFD and QST underwent SCN9A gene analyses. Of these 28 patients with biopsy-confirmed I-SFN, 8 were found to carry novel mutations in SCN9A. Functional analysis revealed multiple gain of function changes in the mutant channels; each of the mutations rendered dorsal root ganglion neurons hyperexcitable.

National Consensus on Diagnosis and Treatment of Pain of Neurological Origin
National Consensus on Diagnosis and Treatment of Pain of Neurological Origin Under the supervision of Acad. Prof. I. Milanov, MD, PhD, DSc. By initiative of the Bulgarian Headache and Pain Association 3 Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Classification By its duration pain is classified as acute and chronic. Acute pain is a symptom, chronic pain is a disease. Acute pain is related to clearly identified tissue injury and lasts no more than 1 month from its onset. It is protective and gradually resolves as the injured tissues heal, when the environment surrounding the nociceptors is normalized and their hyperactivity resolved. Chronic pain persists for more than 3 months. It is caused by tissue damage but continues even after the causative lesion heals. It is not due to activation of nociceptors and has no protective effect. According to the underlying pathophysiological mechanisms pain is classified as nociceptive or neuropathic. The combination of both types (mixed) pain is common. According to its anatomical location pain is classified as head, face and mouth pain; cervical pain; pain in shoulders and arms; thoracic; abdominal; lumbar pain; pain in lower limbs; pelvic; anal, perianal and genital pain. Nociceptive pain It is caused by injury to any organ or system other than the nervous system, and its diagnosis and treatment is associated with a number of medical specialties. It is subdivided into physiological nociceptive pain, caused by temporary dysfunction (cramps, colics), and pathological nociceptive pain, caused by tissue injury. Neuropathic pain It is pain caused by dysfunction, lesion or disease directly affecting the somatosensory nervous system.

PEDIATRIC NEUROLOGY BRIEFS A MONTHLY JOURNAL REVIEW J. GORDON MILLICHAP, M.D., F.R.C.P., EDITOR Vol. 27, No. 5 May 2013 NEUROMUSCULAR DISORDERS SMALL-FIBER POLYNEUROPATHY AND PAIN SYNDROMES Investigators at the Massachusetts General Hospital, Boston, MA, tested the hypothesis that acquired small-fiber polyneuropathy (SFPN) contributes to unexplained widespread pain syndromes in children and adolescents. Medical records of 41 consecutive patients were analyzed for objective diagnostic test data for SFPN. These included skin biopsy, nerve biopsy, and autonomic function testing, plus histories, symptoms and signs, and treatments. Healthy matched volunteers acted as normal controls for SFPN tests. In this polyethnic patient sample, age at illness onset averaged 12.3 +/- 5.7 years; 73% were female, 68% chronically disabled, and 68% had been hospitalized. Objective diagnostic test results were definite for SFPN in 59%, probable in 17%, and possible in 22%. Only 1 had normal SFPN test results. Somatic complaints other than pain were reported in 98% patients and were consistent with SFPN dysautonomia (90% cardiovascular, 82% gastrointestinal, and 34% urological). Chronic fatigue was reported in 83% and chronic headache in 63%. Neurological examinations identified reduced sensation in 68% and vasomotor abnormalities in 55%, including erythromelalgia in 23%. Tests for causality of pain revealed only a history of autoimmune disease elicited in 33% and serologic markers of disordered immunity in 89%. Treatment with corticosteroids and/or IV immunoglobulin benefited 80% of patients (12/15), both objectively and subjectively. (Oaklander AL, Klein MM.
