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.

Osteoarthritis: Complementary Therapies ReviewedABSTRACT: Many patients with osteoarthritis (OA) try such complementary therapies as special diets, nutritional and herbal supplements, yoga, t'ai chi, magnets, and acupuncture-but only 40% of these patients tell their physicians. Glucosamine and chondroitin sulfate can produce at least symptomatic relief; in addition, glucosamine (1500 mg/d) may increase or stabilize cartilage in osteoarthritic knees. Alert patients to the potential toxicities of many herbal remedies, as well as the risks of harmful drug interactions and possible contaminants and impurities. Yoga postures may have a beneficial effect on knee OA; t'ai chi may reduce joint pain and swelling and increase mobility. Small studies have shown that applied pulsed electromagnetic fields can reduce pain and improve function in patients with chronic knee OA. Acupuncture has also been shown, in small studies, to alleviate the pain of OA. Autologous chondrocyte transplantation was recently approved for treatment of knee OA. The efficacy and safety of various types of gene therapy are currently being evaluated.

Dyslipidemia: How Aggressively to Intervene in the Older Patient?ABSTRACT: Lipid abnormalities are extremely prevalent among the elderly, a group at very high risk for cardiovascular disorders. Accordingly, the treatment guidelines of the National Cholesterol Education Program Adult Treatment Panel do not suggest that lipid management be any less aggressive in older patients than in younger ones. Management decisions focus on the calculated low-density lipoprotein cholesterol level as part of a full fasting lipid panel. Dietary counseling remains an important element in the management of lipid disorders, but almost all elderly patients require medications to reach their lipid goals. The statins are the mainstay of treatment for most patients, but some will require additional agents, such as a fibrate, niacin, ezetimibe, fish oil, or a bile acid sequestrant.

Case In Point: Acute eosinophilic pneumonia in a 19-year-old manThe authors describe a case of acute eosinophilic pneumonia (AEP) that occurred in a previously healthy young man. The presentation was similar to that of acute respiratory distress syndrome (ARDS), and the diagnosis was established by bronchoalveolar lavage (BAL). The authors note that it is important to recognize the subset of patients with AEP who present with an ARDS-like picture, especially since corticosteroids are very effective in this setting.

The Dangers of ATVsAn all-terrain vehicle-ATV-is described by the American National Standards Institute as one that "travels on low pressure tires, with a seat that is straddled by the operator, and with handlebars to be used for steering."1 By this definition, an ATV is designed for interactive riding by a single operator. Drivers are able to shift their weight freely in all directions depending on the situation and terrain. According to ATV safety standards and recommendations, children younger than 6 years are never to be on an ATV of any size-alone or with someone else.

High-Risk Hypertensive Patients:ABSTRACT: In high-risk patients with vascular disease, blockade of the renin- angiotensin system (RAS) can help prevent cardiac remodeling that ultimately results in left ventricular hypertrophy (LVH) and heart failure. Optimal treatment of these patients, who often have diabetes or renal disease, usually involves a combination of agents-1 of which should be a thiazide diuretic-to reduce blood pressure, control the comorbid condition, and prevent end-stage organ damage. The manner in which the RAS is interrupted may be important. For example, although a thiazide diuretic and an angiotensin-converting enzyme (ACE) inhibitor are recommended for hypertensive patients with LVH, an angiotensin II receptor blocker (ARB) in combination with a diuretic was recently found to reduce cardiovascular morbidity and mortality in these patients to a greater degree than a ß-blocker/diuretic. Both ACE inhibitors and ARBs delay the progression of diabetic nephropathy and reduce albuminuria. ARBs were recently shown to reduce progression from microalbuminuria to macroalbuminuria. In patients with systolic heart failure who cannot tolerate ACE inhibitors, an ARB can be used with a ß-blocker.
