Because streptokinase is a bacteri- al product discount prazosin 1 mg on-line, it stimulates antibody production and can prompt allergic reactions buy prazosin 1 mg with visa. Antistreptococcal antibodies, which are present in variable titers in most patients before streptokinase treatment, induce an amnestic response that makes repeated treatment with streptokinase difficult or impossible for a period of months or years after an initial course of treatment. A 72-year-old man presents to the hospital with a hip fracture. An orthopedist is planning surgical repair and asks you to see the patient in consultation for preoperative assessment and advice. In particular, the orthopedist asks you to assess the patient’s need for prophylaxis against venous thrombosis and to com- ment on the best prophylactic regimen for the patient. Which of the following statements regarding primary prophylaxis against venous thrombosis and thromboembolism is true? Oral anticoagulation is the method of choice for moderate-risk general surgical and medical patients ❏ B. Prophylactic therapy should typically be discontinued at the time of discharge for patients who have undergone major orthopedic surgery ❏ C. LMWH is more effective than standard low-dose heparin in patients undergoing elective hip surgery ❏ D. For patients undergoing genitourinary, neurologic, or ocular surgery, the most appropriate method of prophylaxis is oral anticoagulation Key Concept/Objective: To know the correct methods of prophylaxis for venous thrombosis and thromboembolism in medical and surgical patients Low-dose-heparin prophylaxis is the method of choice for moderate-risk general surgical and medical patients. It reduces the risk of VTE by 50% to 70% and is simple, inexpensive, convenient, and safe. Extended prophylaxis with LWMH or warfarin for an additional 3 weeks after hospital discharge should be considered after major orthopedic surgery. Extended prophylaxis is strongly recommended for high-risk patients (e. LMWH is more effective than standard low-dose heparin in general surgical patients, patients undergoing elective hip surgery, and patients with stroke or spinal injury.

Clinical syndrome Viral myositis Influenza virus myositis is characterized by severe pain, tenderness and swell- ing which usually affects the calf muscles but may also affect thigh muscles. Myalgia is the most common symptom, and starts approximately one week after the onset of the influenza infection, and then persists for another 2–3 weeks. The disorder is usually self-limiting, however in rare cases it may be severe with myoglobinuria and a risk of renal failure. Coxsackie virus infection is character- ized by a wide spread acute myositis which may be severe and may be associated with myoglobinuria. Epidemics of Coxsackie virus infection tend to occur during the summer and fall. In children aged 5–15 years there may be a self-limiting acute inflammatory myopathy.
