Currently, 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.

ABSTRACT: The number of medical therapies for patients with erectile dysfunction (ED) has increased in recent years because of our expanded understanding of the physiologic and neurologic causes of ED. Oral agents range from testosterone to antidepressants to phosphodiesterase inhibitors. Nitroglycerin and minoxidil have shown some effectiveness as topical agents. Alprostadil, which can be applied intraurethrally, is also effective as intracavernosal injection therapy. Prostaglandin E1 and papaverine are effective as intracavernosal injection agents. Some studies have shown that combined use of intracavernosal injection and oral therapy produces satisfactory erections.
Three days after having eaten fish, a 66-year-old woman with a known allergy to fish and a history of schizophrenia was brought to the emergency department because of macroglossia-a presentation of anaphylaxis. The patient refused airway management (intubation or cricothyrotomy) and was therefore admitted to the medical intensive care unit for monitoring of her airway and hemodynamic status. She received corticosteroids, ranitidine, diphenhydramine, epinephrine, and oxygen (via nasal cannula).
Abstract: The manifestations of indoor mold-related disease (IMRD) include irritant effects, such as conjunctivitis and rhinitis; nonspecific respiratory complaints, such as cough and wheeze; hypersensitivity pneumonitis; allergic fungal sinusitis; and mycotoxicosis. The diagnosis of IMRD depends on eliciting an accurate history and excluding preexisting pathology that would account for the patient's symptoms. Laboratory tests, imaging studies, and spirometry can play an important role in ruling out other diagnoses, such as allergic or nonallergic rhinitis, asthma, and pneumonia. The diagnosis of IMRD also involves integrating the results of immunologic, physiologic, and imaging studies with the results of indoor air-quality studies. (J Respir Dis. 2005;26(12):520-525)

abstract: Proper assessment of the child's readiness for extubation and preparation for extubation are essential to minimize the need for reintubation and to maximize the child's safety in the periextubation period. Readiness for extubation requires that the child have adequate respiratory drive, the ability to maintain a patent airway, adequate oxygenation, and ability to ventilate spontaneously. Respiratory drive can be assessed by decreasing the ventilator settings to a minimal level and observing the child's respiratory effort and respiration rate. Evidence of increased work of breathing, such as tachypnea, retractions, and nasal flaring, suggests that the child may not be ready for extubation. If stridor and respiratory distress develop after the endotracheal tube is removed, nebulized racemic epinephrine is often quite effective; in addition, intravenous corticosteroids should be administered for 24 hours to help decrease the edema more quickly.

abstract: While the risk factors for aspiration pneumonia are similar to those for aspiration pneumonitis, the 2 syndromes have different presentations. Aspiration pneumonia tends to occur in older patients or in those with neurological diseases, and the aspiration is not usually witnessed. Aspiration pneumonitis is more likely to occur in patients undergoing anesthesia or in those with acute drug and alcohol overdoses, and the aspiration is often witnessed. The workup may include bedside assessment of the cough and gag reflexes, chest radiography, videofluoroscopic imaging, or fiberoptic endoscopy. Empiric antibiotic therapy should be avoided in most patients with pneumonitis; however, antibiotics may be indicated for those at high risk for bacterial colonization of oropharyngeal and gastric contents who have fever, increasing sputum production, or new infiltrates or for those who fail to improve within 48 hours. (J Respir Dis. 2007;28(9):370-385)

When you suspect blunt nerve trauma, referral to a hand surgeon is prudent-even without evidence of acute compartment syndrome. The same is true if you discover ischemia in any part of the hand after injury. Try to control hemorrhage with compression and elevation of the involved extremity. If this is unsuccessful, use a short-duration tourniquet. Do not attempt to clamp a bleeding vessel; the risk of causing serious nerve or tendon damage is too high. Avoid exploring wounds in the region distal to the midpalmar crease and proximal to the proximal interphalangeal flexor crease because of the high risk of damaging the flexor tendons and the annular ligaments in this region. Explore more proximal injuries cautiously to determine occult injury to the flexor tendon.
Q:Is periodic laboratory monitoring recommended for patients withosteoarthritis who are receiving long-term cyclooxygenase-2 (COX-2)inhibitor therapy and who have no GI or renal symptoms? Similarly,is laboratory monitoring recommended for women who take a selectiveCOX-2 inhibitor to alleviate menstrual cramps (eg, rofecoxib, 50 mg/d,3 to 5 days per month)?--Sarita Salzberg, MDColumbus, Ohio
Numerous factors put elderly patients at risk for adverse drug events. On average, they take at least 6 medications a day, which increases the likelihood of drug-drug interactions. In addition, many drugs that are safe and effective in younger patients are inappropriate for older persons because of age-related changes and comorbid conditions that affect absorption, distribution, metabolism, and elimination. First-pass metabolism decreases with age, which may increase systemic absorption of some oral nitrates, ß-blockers, estrogens, and calcium channel blockers. The age-related rise in body fat increases the volume of distribution of lipid-soluble compounds, such as diazepam, and prolongs clearance. About two thirds of elderly persons have impaired kidney function; in these patients, the dosage of renally excreted drugs-such as digoxin-needs to be reduced. Other strategies for avoiding adverse drug events are detailed here.
