This is valid if the patient has not been transfused with any blood products for 120 days or pregnant within 120 days. If you are taking any of the following medications, please notify your physician to see what alternative medica tion you may be able to take, or if it is safe to discontinue the medication.

John’s Wort Diet Supplements (Check with Primary Care physician about stopping) i. The Textbook of 1 Adverse Drug Reactions defnes “drug allergy” as mediated by immunological mecha nisms. Allergic drug reactions are categorized as a type B (bizarre) adverse drug reaction. These reactions are totally aberrant effects that are not to be expected from the known pharmacological actions of a drug when given in the usual therapeutic doses. They are usually unpredictable and are not observed during conventional pharmacological and toxicological screening programs. Although their incidence and morbidity are usually low, their mortality may be high. In contrast, an intolerance to a drug is categorized as a type A (augmented) adverse drug reaction. These reactions are the result of an exaggerated, but otherwise normal, pharmacological action of a drug given in the usual therapeutic doses. Examples include bradycardia with beta-blockers, hemorrhage with anticoagulants, or drowsiness with benzodiazepines. Type A reactions are largely predictable on the basis of a drug’s known pharmacology. Drug therapy can often be continued with an alteration in dose or other intervention. They are usually dose-dependent and although their incidence and morbidity are often high, their mortality is generally low. Obviously, if a patient has a true allergy to a drug or class of drugs, we want to be aware not to expose the patient to a potentially dangerous or life-threatening situation. However, if a drug is listed as an allergy, but in actuality the patient has not demonstrated allergic symptoms but has experienced an intolerance such as nausea or gastrointestinal distress, the patient should not be precluded from future treatment with the drug as warranted. Example: A patient comes to the emergency room with sustained chest pain and history of angina, hypertension, and coronary artery disease. Morphine (and other narcotic analgesics to a lesser de gree) is desirable for pain associated with ischemia because of its cardiovascular effects of venous pooling in the extremities causing decreased peripheral resistance. This effect results in decreases in venous return, cardiac work, and pulmonary venous pressure, thus decreasing oxygen demand by the heart. When the family is interviewed, they describe the patient’s “allergy” as vomiting in response to morphine following a previous hospitalization. Morphine causes a central nervous system effect on the vomiting center to cause nausea and vomiting by depressing the vomiting center. An increase in vestibular sensitivity may also contribute to the high incidence of nausea and vomiting in ambulatory patients. By questioning the patient’s family, the emergency room staff was able to conclude that the patient was not truly al lergic to morphine. Acute pericarditis typically appears within a year of therapy and may result in tamponade. Chronic pericarditis usually causes an asymptomatic pericardial effusion presenting several years after therapy. Chronic pericarditis may resolve spontaneously or may progress to constrictive pericarditis. The overall incidence is low, but risk increases with higher doses, particularly with those delivered to an anterior feld. Patients with a history suggestive of myocardial ischemia who have received mediastinal irradiation should be carefully evaluated regardless of age. The electrocardio gram may be abnormal in many patients but may not predict coronary or pericardial disease. The side effects to the nitrosoureas are quite similar and these agents have not been subcategorized. Several agents have been omitted: mithramycin, which causes hypocalcemia, liver toxicity, and facial fushing; and hormonal agents (androgens, estrogens, anitestrogens, progestigens, and adrenal corticosteroids), which cause uniform predictable side effects characteristic of each hormone. Other Infectious Diseases Bacterial sepsis Babesia Malaria Syphilis All rare; no accurate data available. A Report by the American Society of Anesthesiologists Task Force on Blood Component Therapy. Report to the Ranking Minority Member, Committee on Commerce, House of Representatives. The typical presentation was reported as abdominal pain associated with symptoms such as constipation and vomiting. Gastrointestinal perforations (including gastrointestinal fistula and abscess) have been reported in up to 2. General No studies on the effects on the ability to drive and use machines have been performed. In order to improve the traceability of biological medicinal products, the trade name and the batch number of the administered product should be clearly recorded (or stated) in the patient file. These events included infectious endophthalmitis (some cases leading to permanent blindness, one case reported extraocular extension of infection i resulting in meningoencephalitis), intraocular inflammation (such as sterile endophthalmitis, uveitis, and vitritis) (some cases leading to permanent blindness), retinal detachment, retinal pigment epithelial tear, intraocular pressure increased, intraocular hemorrhage (such as vitreous hemorrhage or retinal hemorrhage), conjunctival hemorrhage. The most frequent serious systemic adverse events reported directly to the sponsor include myocardial infarction, cerebrovascular accident, and hypertension. Clinical safety data suggest that the incidence of hypertension is likely to be dose-dependent. In most cases hypertension was controlled adequately using standard antihypertensive treatment appropriate for the individual situation of the affected patient. The use of diuretics to manage hypertension is not advised in patients who receive a cisplatin-based chemotherapy regimen. Risks of mortality, myocardial infarction, bleeding, and stroke associated with therapies for age related macular degeneration. The typical presentation may include abdominal pain, nausea, emesis, constipation, and fever. Patients with a 2+ or greater urine dipstick reading should undergo further assessment with a 24-hour urine collection. In a published case series, kidney biopsy of six patients with proteinuria showed findings consistent with thrombotic microangiopathy. Routine assessment of this event should include serial complete blood counts and physical examination. Page 11 of 95 Patients should be closely monitored for signs of febrile neutropenia, and white blood cell count carried out according to local oncology standards. Treatment of neutropenia and febrile neutropenia should follow established oncological standards. Patients > 65 years of age appeared to be at higher risk for Grade ≥3 thrombocytopenia compared with younger patients. Hypersensitivity Reactions, Infusion Reactions Patients may be at risk of developing infusion/hypersensitivity reactions. Close observation of the patient during and following the administration of bevacizumab is recommended as expected for any infusion of a therapeutic humanized monoclonal antibody. If a reaction occurs, the infusion should be interrupted and appropriate medical therapies should be administered. A systematic premedication specifically for bevacizumab administration, in general, is not warranted; however, use of premedication should be based on clinical judgment. Infusion reactions reported in the clinical trials and post-marketing experience include hypertension, hypertensive crises associated with neurologic signs and symptoms, wheezing, oxygen desaturation, Grade 3 hypersensitivity, chest pain, headaches, rigors, and diaphoresis.

The Evidence-based Practice Knee Panel downgraded the evidence from “C” to “I” and a majority concluded (60% agrees, 20% disagrees, and 20% neutral) that platelet rich plasma injections should not be recommended for moderate to severe knee osteoarthrosis based on the lack of quality placebo-controlled trials. In addition, the Evidence-base Practice Knee Panel concluded there is insufficient evidence to conclude either for or against a recommendation (40% agree, 40% disagree, and 20% neutral) for autologous blood injections for moderate to severe knee osteoarthrosis based on the lack of quality trials regarding the overall efficacy of these injections.

There are 1-high and 9-moderate trials comparing injections with viscosupplementation with glucocorticosteroid. Most of these trials comparing viscosupplementation with glucocortoid injection suggested glucocorticosteroid injections are inferior for the knee;(1384-1390) however, for the hip the reverse may be true. One high-quality trial suggested comparable results until 26 weeks at which point the glucocorticoid appeared to be losing benefit while the benefits of the viscosupplementation had greater persistence. There is one moderate-quality trial reporting a lack of synergism with combined glucocorticoid injection. Both resulted in approximately 40% reductions in pain ratings with benefits lasting 6 months. Various combinations of injections have not shown one regimen to be clearly superior. The Evidence-based Practice Knee Panel has downgraded the evidence from “C” to “I” and came to a limited conclusion (50% agrees, 16.
