Using low molecular weight heparins as "bridging anticoagulant therapy"Abstract: Bridging anticoagulant therapy is used to minimize the risk of thromboembolic complications when warfarin therapy must be temporarily interrupted because of surgery or another procedure. The decision to use this strategy depends on the patient's risk of thromboembolic complications and the risk of bleeding associated with the specific procedure. One approach is to withhold 4 or 5 daily doses of warfarin before surgery and initiate low molecular weight heparin (LMWH) 3 or 4 days before surgery. The last dose of LMWH is administered at least 24 hours before the procedure. After the procedure, prophylactic-dose LMWH can be administered subcutaneously once daily. The use of therapeutic-dose LMWH should be deferred until at least 24 or 48 hours after procedures that have a low or moderate risk of bleeding and until 48 or 72 hours after high-risk procedures.

Pertussis: A cause of cough in adults as well as childrenSince pertussis has been considered to be primarily apediatric disease, it is often overlooked as a cause of cough inadults. However, the incidence has been increasing in adolescentsand adults, and these persons are the major reservoir forthe disease. The first stage of illness is characterized by flu-likesymptoms; then patients typically have paroxysms of severecoughing-several short dry coughs, followed by a deep inspiratoryeffort and the characteristic "whoop." The most commoncomplication of pertussis is pneumonia, but other complicationsinclude bronchitis, laryngitis, atelectasis, pneumothorax,subconjunctival hemorrhage, subdural hematoma,and seizures. The diagnosis can be confirmed by isolation ofBordetella pertussis in culture; rapid diagnostic tests, such as thedirect fluorescent antibody method and polymerase chain reaction;and serological tests to detect antibodies to B pertussis.First-line therapy for pertussis includes a macrolide antibiotic.(J Respir Dis. 2008;29(4):172-178)

Monitoring adolescents with cystic fibrosisabstract: There is increasing evidence that close monitoring and early intervention lead to better outcomes in patients with cystic fibrosis. At each office visit, spirometry should be performed and sputum culture specimens should be obtained; if the patient cannot produce sputum, a throat culture can be done instead. New respiratory symptoms or other evidence of worsening lung disease should prompt antibiotic therapy, increased airway clearance, and adjunctive anti-inflammatory medication as appropriate. Close attention should be paid to the patient's diet, appetite, stooling pattern, and growth measurements. Adolescents should be given additional information about their medications and adjunctive therapies to encourage them to take on a larger role in their own care. (J Respir Dis.2006;27(7):298-305)

Escherichia coli in Traveler's DiarrheaTraveler's diarrhea (TD) occurs in persons traveling fromindustrialized countries to less developed regions of the world.Because of the growing ease of travel and an increasinglyglobalized economy, TD is becoming more common. Increasingantibiotic resistance among causative bacterial organisms andalso emergence of new pathogens are additional challenges inthe management of TD. Enterotoxigenic and enteroaggregativepathotypes of Escherichia coli are the principal causes of TD.This review discusses the epidemiology of these pathogens, aswell as elements of prevention, diagnosis, and management.[Infect Med. 2008;25:264-276]

Monitoring the response to therapy for pulmonary arterial hypertension, part 2Despite the recent development of several new therapies, pulmonary arterial hypertension (PAH) remains an incurable disease. Careful monitoring of disease progression is vital to ensuring that patients receive maximal medical therapy before the onset of overt right-sided heart failure. In part 1 of this article, I reviewed the role of the history and physical examination, chest radiography, electrocardiography, echocardiography, and pulmonary artery catheterization. In part 2, I focus on MRI, cardiopulmonary exercise testing (CPET), the 6-minute walk test, and biomarkers.
