Refractory Ulcer:What to Do Next?ABSTRACT: Undiagnosed or persistent Helicobacter pylori infection and surreptitious or unrecognized NSAID use are the most common causes of refractory peptic ulcers. The use of antibiotics, bismuth, or proton pump inhibitors (PPIs) suppresses the H pylori bacterial load and may obscure the diagnosis. H pylori infections have also become more difficult to cure because of increased antibiotic resistance. For refractory infection, select an antibiotic based on in vitro susceptibility testing. When this is not available, combination therapy with a PPI, tetracycline, metronidazole, and bismuth is often effective. To detect surreptitious or inadvertent NSAID use, review the drug history in detail. When there is any doubt about such use, check platelet cyclooxygenase function.

Acute Suppurative Thyroiditis in a Patient With Aplastic AnemiaAcute suppurative thyroiditis (AST) is a rare inflammatorycomplication in patients with hematological malignancy.Infection spreads to the thyroid from a distant site throughthe bloodstream or the lymphatics. Defects such as persistentthyroglossal duct and pyriform sinus fistula are associatedwith the development of AST. Ultrasonography, bariumswallow testing, CT, and fine-needle aspiration are usedfor diagnosis. Treatment includes the administration ofparenteral antibiotics, drainage, and excision. We describea patient with aplastic anemia and bacteremic AST.[Infect Med. 2008;25:339-342]

Stroke: Update on New Therapies- and the Implications for Primary CareCurrently, the only approved therapy for acute ischemic stroke is tissue plasminogen activator (tPA), initiated within 3 hours of stroke onset. New patient selection criteria are emerging that may improve the effectiveness and safety of thrombolysis. For example, evidence of extensive early ischemia on CT may predict a poor outcome regardless of whether tPA is administered. New imaging techniques, such as diffusion MRI, perfusion MRI, and MR angiography, may be able to identify salvageable tissue and distinguish it from irreversibly damaged tissue. Such findings may allow the 3-hour window for tPA therapy to be extended in certain patients. Other approaches to ischemic stroke therapy that are being studied include intra-arterial thrombolysis, new thrombolytic agents, platelet aggregation inhibitors, endovascular interventional techniques (alone and in combination with pharmacologic thrombolysis), and neuroprotective therapy with various agents to ameliorate the consequences of ischemia in brain tissue.

Acute Poisoning:We live in a world of toxins and potential toxins, and thus we are often just a misstep away from a toxic exposure and its consequences. Even that which is meant to cure can kill. All substances are poisons; there is none which is not a poison. The right dose differentiates a poison and a remedy; exposure to the wrong dose of a medication (whether accidental or not) remains a common form of toxic exposure.

Extrapulmonary tuberculosis, part 4: Skeletal involvementAbstract: Spinal tuberculosis is the most common form of osteoarticular involvement in patients with tuberculosis. Localized pain is a common presenting symptom. In patients who do not present until vertebral wedging and collapse have occurred, a localized knuckle kyphosis is obvious, especially in the dorsal spine. In some patients, a retropharyngeal abscess develops, causing dysphagia, dyspnea, and/or hoarseness. Peripheral joint tuberculosis is characterized by an insidious onset of slowly progressive, painful, and swollen monoarthropathy, most commonly affecting the hip or knee. The radiologic features include juxta-articular osteoporosis, peripheral osseous erosion, and gradual narrowing of the interosseous space. Treatment involves antituberculosis drugs; the indications for surgery are relatively limited. (J Respir Dis. 2005; 26(12):543-546)
