SAN FRANCISCO -- Older men with limited life expectancies are getting screened much too often for prostate cancer, given the potential harm that may follow a positive test versus the likelihood of benefit, researchers here reported.

NEW YORK -- Uncomplicated diabetes does not affect 10-year heart transplant survival, but patients with diabetes-related renal disease or stroke do not do as well, reported surgeons here.

ROCHESTER, Minn. -- Mortality rates for heart failure patients with preserved left ventricular ejection fraction (non-systolic) are similar to those for patients with a reduced ejection fraction (systolic). However, a higher systolic pressure on admission was a marker of better prognosis.

Abstract: Our understanding of the pathobiology of pulmonary arterial hypertension (PAH) has evolved considerably over the past 2 decades, with increasing recognition of the important role that aberrant vasoproliferative responses play in conjunction with disordered vasoconstriction. Classification of the many forms of PAH into categories sharing a similar pathophysiology and clinical presentations help the practicing clinician approach a complex differential diagnosis. Noninvasive tests can be used to narrow this differential but must be applied with an appreciation for their limitations. Transthoracic echocardiography is the screening tool of choice; the workup should also include chest radiography and electrocardiography. However, right heart catheterization is ultimately required to establish the diagnosis. While PAH remains a progressive and generally fatal disease, existing therapies have a significant impact on survival and new therapeutic targets offer great hope for improving the prognosis.

ABSTRACT: Establishing the time of symptom onset is essential to selecting the appropriate therapy. Intravenous tissue-type plasminogen activator (t-PA), administered within 3 hours of symptom onset, is the only FDA-approved treatment for acute ischemic stroke. Intra-arterial and combined intra-arterial-intravenous thrombolytic therapy may be considered for patients whose condition does not improve or who present within 3 to 6 hours of symptom onset. Other options for treating acute ischemic stroke are balloon angioplasty with or without stenting (for symptomatic patients with more than 50% intracranial stenosis in whom medical therapy has failed) and mechanical clot retrieval (for those with an NIH Stroke Scale score greater than 10 who present after the 3-hour window for intravenous t-PA and can be treated within 8 hours of symptom onset or who present within 3 hours of symptom onset but in whom intravenous thrombolysis is contraindicated).

THECASE:An 84-year-old man with a history of stable angina, type 2 diabetes, hyperlipidemia, and hypertension presents to the emergency department with worsening dyspnea and peripheral edema. Congestive heart failure is diagnosed, and the patient is admitted to the care of a hospitalist. A standard therapeutic regimen, including diuretics, angiotensin-converting enzyme inhibitors, and oxygen, is instituted, in addition to the patient's home regimen of isosorbide mononitrate, glipizide, and amlodipine. The hospitalsubstitutes pravastatin for the patient's atorvastatin. A Foley catheter is inserted by a urologist because of the patient's benign prostatic hypertrophy. The patient complains of insomnia and is given diphenhydramine. His hospital course is otherwise uneventful.

If Rip Van Winkle were a primary care physician who fell asleep a generation ago and woke up today, what would he think? He would have missed the arrival of managed care. He wouldn't know what a hospitalist does. He might ask how this evasive concept called quality is measured . . . and then cringe at the idea of "report cards" and "pay for performance."

GRENOBLE, France -- The risk of deep venous thromboembolism (DVT) in older patients could be significantly reduced if clinicians in post-acute care settings took to heart evidence-based guidelines, according to French researchers.

NEW ORLEANS -- For converting atrial fibrillation to sinus rhythm in patients on rate-control or rhythm-control background therapy, an investigational injectable was generally effective within 10 minutes, investigators reported here.

GOLDEN, Colo. -- More than 300,000 Medicare patients died from 2003 to 2005 because they were hospitalized in institutions that were average or poor on report cards issued today by HealthGrades, a for-profit health care quality rating service here.

NEW YORK -- Survivors of childhood cancer may face futures fraught with vastly greater chronic and life-threatening health risks than those of their siblings, according to a large retrospective study.
