Considering the role of NPPV, PEEP, and other interventions Managing acute severe asthma: What therapies to try, part 2 key words: Asthma, Leukotriene modifiers, Mechanical ventilationabstract: The mainstay of therapy for acute severe asthma includes ß2-agonists, anticholinergics, and corticosteroids. Other agents, such as leukotriene modifiers and magnesium sulfate, can be used in patients who have responded poorly to conventional therapy. Noninvasive positive pressure ventilation (NPPV) should be tried before intubation in alert, cooperative patients who have not improved with aggressive medical therapy. However, NPPV should not be attempted in patients who are rapidly deteriorating or in those who are somnolent or confused. Endotracheal intubation is recommended for airway protection or for patients who present with altered mental status or circulatory shock. Patients should be admitted to the ICU if they have difficulty in talking because of breathlessness, altered mental status, a forced expiratory volume in 1 second or peak expiratory flow rate of less than 25% of predicted, or a PaCO2 greater than 40 mm Hg after aggressive treatment in the emergency department.

Preventive measures are still the best strategy Aspiration syndromes: Pneumonia and pneumonitis key words: Aspiration, Pneumonitis, Pneumoniaabstract: 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.

Polymicrobial Wound Infection and Nerve Injury Secondary to a Nonhuman Primate BiteNonhuman primate bites in the United States are rare. Mostphysicians have no experience managing them. The lesionsare initially treated in much the same way as human bites,although consultation with an infectious diseases specialist,surgeon, and veterinarian are recommended, especially formicrobial infection control and management. Of particularconcern is animal-to-human transmission of herpes B virus,which can be fatal. We report a case of polymicrobial simianbite wound infection with associated nerve injury in a12-year-old boy. [Infect Med. 2008;25:120-122]

Crossed Renal Ectopia With FusionFrequent urinary tract infections and unexplained hypertension (160/100 mm Hg) occurred in a 38-year-old man with no significant medical history. The heart and chest were normal; a right lower quadrant mass was detected in the abdomen. Red blood cells were found in the urine. An abdominal CT scan demonstrated that the left kidney was fused to the lower pole of the right kidney with the left pelvicaliceal system to the left of the midline; these findings are consistent with crossed fused renal ectopia. Cystographic and cystoscopic examinations were normal.

A patient with hemoptysis, anemia, and renal failureMicroscopic polyangiitis is a potentially fatal disease if it is notrecognized and treated early. In the case described here, what initiallypresented as a postinfectious residual cough was actuallyactive pulmonary hemorrhage, severe anemia, and a crescenticglomerulonephritis. Significant improvement was achieved withhemodialysis and aggressive treatment with corticosteroids andcyclophosphamide. This case exemplifies a classic presentationof microscopic polyangiitis and demonstrates the importance ofan expeditious diagnostic evaluation and early treatment to preventrapid deterioration. Early recognition and highly aggressiveimmunosuppressive treatment achieved significant suppressionof the disease.
