Extensive Computed Tomography versus Limited Screening for Detection of Occult Cancer in Unprovoked Venous Thromboembolism: A Multicenter, Controlled, Randomized Clinical Trial.

Patients with unprovoked venous thromboembolism (VTE) may harbor occult cancer. Whether an extensive diagnostic work-up for cancer has additional value over a more limited screening for detection of underlying malignancy in these patients is controversial. We performed a randomized multicenter trial to assess if in patients with unprovoked VTE, a computed tomography (CT)-based diagnostic strategy including thoracic, abdominal, and pelvic CT in combination with fecal occult blood test yields a higher cancer detection rate than a nonstandardized testing approach based on physicians' clinical judgment and patients' preferences.

Management of patients with low-risk chest pain at the time of admission: a prospective study on a non-selected population from the Emergency Department.

Background: The management of patients with acute chest pain is a common and difficult challenge from the epidemiological, clinical, organizational and malpractice points of view. Our purpose was to test and implement a simple clinical protocol for the management of patients with acute chest pain and at low-risk for an acute coronary syndrome (ACS) at the time of admission to the Emergency Department (ED).

Methods: During a 5-month study period, 570 consecutive patients were admitted to the ED with acute chest pain: 224 patients were excluded owing to the presence of a clear diagnosis of an ACS or of high-risk factors.

[Is a more efficient operative strategy feasible for the emergency management of the patient with acute chest pain?].

Patients with acute chest pain are a common problem and a difficult challenge for clinicians. In the United States more than 5 million patients are examined in the emergency department on a yearly basis, at a cost of 6 billion dollars. In the CHEPER registry the prevalence of patients with chest pain in the Emergency Department was 5.
