    1. Cephalosporins or extended-spectrum penicillins are commonly used (eg, cephalexin, 0.5 g orally four times daily for 7–10 days; see Table 35–6). Trimethoprim-sulfamethoxazole (two double-strength tablets orally twice daily for 7–10 days) should be considered when there is concern that the pathogen is MRSA (see Tables 35–5 and 35–6). Vancomycin, 15 mg/kg intravenously every 12 hours, is used for patients with signs of a systemic inflammatory response.

      cephalexin, dicloxacillin, penicillin VK, amoxicillin/clavulanate, or clindamycin (for penicillin-allergic patients). [1-2] These beta-lactam antibiotics provide excellent coverage against streptococci and methicillin-susceptible S. aureus (MSSA

    1. Urgent treatment for neoplasm consists of (1) cautious use of intravenous diuretics and (2) mediastinal irradiation, starting within 24 hours, with a treatment plan designed to give a high daily dose of radiation but a short total course of therapy to rapidly shrink the local tumor. Intensive radiation therapy combined with chemotherapy will palliate the process in up to 90% of patients. In patients with a subacute presentation, radiation therapy alone usually suffices. Chemotherapy is added if lymphoma or small-cell carcinoma is diagnosed

      endovascular stenting emerging as first-line therapy for rapid symptom relief, while definitive treatment targets the underlying cause

      Glucocorticoids (dexamethasone 4 mg every 6 hours) are commonly prescribed but lack robust supporting data; they may be more beneficial in lymphoma or thymoma and as prophylaxis against radiation-induced edema. [2-4] Importantly, SVC syndrome is no longer considered a medical emergency except in rare cases with life-threatening cerebral edema, laryngeal edema, or altered mental status. When thrombosis is present, catheter-directed thrombolysis or aspiration thrombectomy should be performed within 2-5 days of symptom onset before thrombus organization occurs. [3] The role of long-term anticoagulation after stenting remains unclear, though it is standard when significant thrombosis is present The American College of Chest Physicians recommends obtaining histologic diagnosis before treatment in suspected lung cancer cases, as stenting does not interfere with tissue diagnosis. [2] For small cell lung cancer (SCLC), chemotherapy alone is recommended as first-line treatment given rapid response rates. [2] For non-small cell lung cancer (NSCLC), radiation therapy and/or stent insertion are recommended, with response rates of 59% for chemotherapy and 63% for radiation therapy. [2] Patients with chemotherapy- or radiation-refractory disease should receive vascular stents For device-related thrombosis (catheters, pacemakers), catheter removal should be considered in conjunction with anticoagulation. [4] Endovascular therapy is first-line for device-related obstruction, while surgical bypass may be preferred for mediastinal fibrosis. [7] Both approaches show good mid-term patency, though secondary interventions are common (approximately 27-28%

    1. Treatment of superficial vein reflux (see Varicose Veins, above) has been shown to decrease the recurrence rate of venous ulcers. Where there is substantial obstruction of the femoral or popliteal deep venous system, superficial varicosities supply the venous return and should not be removed.

      Failure of venous insufficiency ulcerations to heal is most often due to inconsistent use of first-line treatment methods. Ongoing control of edema is essential to prevent recurrent ulceration; the use of compression stockings following ulcer healing is critical, with recurrence rates 2–20 times higher if compression stockings are not used

      Duplex ultrasound evaluation should assess blood flow direction, venous reflux, and venous obstruction, and include examination of the deep venous system, great saphenous vein (GSV), small saphenous vein (SSV) and its thigh extension (Giacomini vein), accessory saphenous veins, and perforating veins. Venography is recommended primarily in patients with post-thrombotic disease, especially when intervention is planned, as it provides greater anatomic detail than duplex ultrasonograph The examination also identifies patterns of disease that have treatment implications. Axial reflux is defined as uninterrupted retrograde flow from groin to calf and can occur in either superficial or deep systems. [4] Junctional reflux is limited to the saphenofemoral or saphenopopliteal junction, while segmental reflux occurs in a portion of a truncal vein. [4] Understanding whether reflux originates from superficial junctions versus deep venous incompetence fundamentally changes treatment planning, as superficial disease is amenable to ablation while deep disease typically requires conservative management Management of secondary varicose veins from post-thrombotic syndrome (PTS) is fundamentally different and more challenging. Compression therapy, lifestyle modifications, and symptom management form the cornerstone of PTS treatment. [4-8] Elastic compression stockings (20-30 mm Hg), leg elevation, weight loss, and exercise constitute the primary therapeutic approach Endovascular interventions for PTS—including percutaneous transluminal venoplasty and stenting—are reserved for select patients with significant iliofemoral obstruction who have failed conservative management. [7] These procedures require careful patient selection and standardized criteria. The role of superficial venous ablation in PTS patients with concomitant superficial reflux remains controversial and should be approached cautiously, as the underlying deep venous pathology may limit benefit

    1. Venoactive drugs (diosmin, hesperidin, horse chestnut seed extract) may be considered as adjuncts to compression for symptomatic relief in countries where available

    2. Endovenous ablation is contraindicated or relatively unsuitable when venous anatomy precludes catheter-based treatment, specifically: aneurysmal dilation of the GSV close to the saphenofemoral junction, subcutaneous location of truncal veins above the saphenous fascia and close to the skin, and significant tortuosity of the GSV or SSV. [1] In these scenarios, high ligation and stripping is recommended as the preferred alternative (grade 1 strong recommendation

    1. Aortic dissection typically presents acutely with sudden, severe tearing chest or back pain, often described as lancinating in quality. [5-6] Approximately 50% of patients with thoracic aortic aneurysm may progress to dissection without timely intervention. [5] In contrast, thoracic aortic aneurysm is usually asymptomatic and discovered incidentally during physical examination or imaging for other indications. [5]

    2. Any patient with chest or back pain with a known or suspected thoracic aorta aneurysm must be brought to the hospital and undergo urgent imaging studies to rule out the aneurysm as a cause of the pain

      elective surgical repair is suggested at 5.5 cm in patients without underlying connective tissue disorders, with earlier intervention at 4.5-5.0 cm in patients with connective tissue disorders or bicuspid aortic valve

    1. Under the Sanders proposal, for example, cost control is secured by a global budget and by imposing Medicare payment rates. Blahous, a former Medicare trustee, estimates that under the Sanders proposal, provider payments would be cut by an estimated 40 percent by usingMedicare payment rates. Using Medicare payment rates throughout the entire American health care economy would hurt patients. Already, the Centers for Medicare and Medicaid Services projects that “nearly half of hospitals, approximately two-thirds of skilled nursing facilities (SNFs), and over 8 percent of home health agencies (HHAs) would have negative total facility margins.”

      The system does not keep a balance between suppliers and consumers. Make up the economy of health care disorders.

    1. Dr. Gandhi, who was finishing her second year of residency at Duke Medical Center in Raleigh, N.C., when the NEJM paper was published, sees the acuity of patients getting worse in the coming years as America rapidly ages. Baby boomers will start turning 80 in the next decade, and longer life spans translate to increasing medical problems that will often require hospitalization.
