The patient is asked to walk up and down a long corridor for up to three minutes at about 120 paces per minute cheap 500mg cephalexin fast delivery. The time of occurrence of symptoms and the site of pain are clinically assessed, as are gait and any pauses. If the patient pauses after only 60 seconds, this suggests disruption of vascular supply to the muscles. Symptoms of moderately severe circulatory disruption will manifest themselves after 1–3 minutes of walking. Symptoms that occur only after three minutes or more of walking indicate only slight circulatory disruption. Note that exercise tolerance may be limited by cardiac and pulmo- nary disorders as well as orthopedic disorders such as osteoarthritis of the hip or degenerative knee disorders.

The patient then makes a fist so as to force the venous blood out of the hand via the posterior veins. The examiner simulta- neously releases compression, first from one artery then from the other. Evaluation: Rapid, uniform reddening of the hand in the areas sup- plied by the respective arteries indicates normal arterial supply. If vascular supply to the hand and fingers is compromised, the ischemic changes in the hand will only slowly recede.

Complementary therapies in neurology 22 SAFETY OF BOTANICAL PRODUCTS—ADVERSE REACTIONS AND INTERACTIONS A large proportion of the general public has the misconception that herbal products are safe because they are of natural origin. While sensible use within the recommended dosage is generally safe for most traditional herbs, adverse reactions may arise from the inherent properties of the herbal ingredients, from misuse, abuse and overuse of products, or from misidentification of plants or adulteration of products. A particularly serious 55 example, reported from Belgium, involved the substitution of the Chinese herb Aristolochia fangchi into slimming pills purportedly containing Stephania tetrandra. The two herbs are considered interchangeable in traditional Chinese medicine, but whereas the latter herb is relatively innocuous, the former contains nephrotoxic and carcinogenic aristolochic acids. Women ingesting these pills developed moderate to end-stage renal disease resulting from renal interstitial fibrosis and urothelial carcinoma, eventually requiring treatment by renal dialysis or transplantation. Chinese herbal medicines have 56 sometimes been found to be adulterated with undeclared synthetic drugs. Examples of 5,26,29,56 adverse events involving herbal products have been summarized in review articles ; 29,57–69 some case reports from the USA are summarized in Table 6. There are certain categories of persons who are at a higher risk of toxic effects of herbs, owing to their altered pharmacokinetic profiles and drug metabolizing capability 70 from the norm. These include fetuses, babies, the elderly, those with pre-existing illness and those who are malnourished. Toxicity is also more likely in users of botanical products with long-term use, consumption of amounts exceeding recommended levels and simultaneous use of many herbal products and conventional drugs.
