Selected AbstractsProspective Study of Accuracy and Outcome of Emergency Ultrasound for Abdominal Aortic Aneurysm over Two YearsACADEMIC EMERGENCY MEDICINE, Issue 8 2003Vivek S. Tayal MD Abstract Determination of the presence of an abdominal aortic aneurysm (AAA) is essential in the management of the symptomatic emergency department (ED) patient. Objectives: To identify whether emergency ultrasound of the abdominal aorta (EUS-AA) by emergency physicians could accurately determine the presence of AAA and guide ED disposition. Methods: This was a prospective, observational study at an urban ED with more than 100,000 annual patient visits with consecutive patients enrolled over a two-year period. All patients suspected to have AAA underwent standard ED evaluation consisting of EUS-AA, followed by a confirmatory imaging study or laparotomy. AAA was defined as any measured diameter greater than 3 cm. Demographic data, results of confirmatory testing, and patient outcome were collected by retrospective review. Results: A total of 125 patients had EUS-AA performed over a two-year period. The patient population had the following characteristics: average age 66 years, male 54%, hypertension 56%, coronary artery disease 39%, diabetes 22%, and peripheral vascular disease 14%. Confirmatory tests included radiology ultrasound, 28/125 (22%); abdominal computed tomography, 95/125 (76%); abdominal magnetic resonance imaging, 1/125 (1%); and laparotomy, 1/125 (1%). AAA was diagnosed in 29/125 (23%); of those, 27/29 patients had AAA on confirmatory testing. EUS-AA had 100% sensitivity (95% CI = 89.5 to 100), 98% specificity (95% CI = 92.8 to 99.8), 93% positive predictive value (27/29), and 100% negative predictive value (96/96). Admission rate for the study group overall was 70%. Immediate operative management was considered in 17 of 27 (63%) patients with AAA; ten patients were taken to the operating room. Conclusions: EUS-AA in a symptomatic population for AAA is sensitive and specific. These data suggest that the presence of AAA on EUS-AA should guide urgent consultation. Emergency physicians were able to exclude AAA regardless of disposition from the ED.

Aim., No inventories are available for the screening of hypogonadism in patients with sexual dysfunction. We wished to set up a brief structured interview providing scores useful for detecting hypogonadism defined as low total T (<10.4 nmol/L, 300 ng/dL) in a symptomatic population (sexual dysfunction). Methods., A minimum set of items was identified within a larger structured interview through iterative receiver-operating characteristic curve analysis, with assessment of sensitivity and specificity for hypogonadism in a sample of 215 patients. Main Outcome Measures., Sensitivity and specificity were verified in a further sample of 664 patients. Correlation of test scores with prostate-specific antigen (PSA), testis volume, and others clinical and psychological parameters, was assessed for concurrent validity. Results., In the validation sample, the final 12-item version of the interview (ANDROTEST,©) had a sensitivity and specificity of 68% and 65%, in detecting low total T (<10.4 nmol/L) and of 71% and 65%, in the screening for low free T (<37 pmol/L). Furthermore, patients with a pathological test (i.e., score >8) showed higher prevalence of hypogonadism-related signs, such as lower testis volume and higher depressive symptoms. Finally, when only younger patients (<54 years, which represents the median age of the sample) were considered, Log10 [PSA] levels were significantly lower in those with ANDROTEST,© score >8. Conclusion., ANDROTEST,© is a quick and easy-to-administer interview that provides scores for the screening of male hypogonadism in patients with sexual dysfunction.

[source] Frequency and impact of extracolonic findings detected at computed tomographic colonography in a symptomatic population,,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 3 2007K. Y. Khan Background: Extracolonic findings are frequently recognized alongside colonic pathology at computed tomographic colonography (CTC). This study assessed the clinical impact of extracolonic findings in a symptomatic population at high risk of colorectal cancer. Methods: CTC was performed in a consecutive cohort of patients assessed in a fast-track colorectal cancer clinic as being at high risk of colorectal cancer. A review of CTC findings and case notes was undertaken. Patients with extracolonic findings were followed up for at least 12 months. Results: Thirty-one (13·8 per cent) of 225 patients investigated by CTC had colorectal cancer. Extracolonic findings were identified in 81 (53·3 per cent) of 152 patients with normal or non-neoplastic bowel findings, compared with 27 (37 per cent) of 73 patients with colorectal neoplasia (P = 0·025). Twenty-four patients (10·7 per cent) with extracolonic findings underwent further investigation or treatment. The median duration of investigation was 19·5 weeks. Seventy-five clinical events were recorded, including 14 surgical procedures. Conclusion: A prospective cost,benefit analysis of diagnostic CTC should be performed before it is established as a first-line investigation for colonic symptoms.
