Fifty-five patients with ankylosing spondylitis and 16 control patients matched for sex and age were examined for evidence of occult inflammatory bowel disease. In all patients evaluation included history and physical examination, barium enema, sigmoidoscopy, and rectal biopsy. The results of this study suggest that there is no increased prevalence of occult inflammatory bowel disease in patien...

The prognosis of oral squamous cell carcinoma (OSCC) is significantly dependent on the existence of cervical lymph node metastasis (LNM), with the overall survival rate being much lower in patients with LNM. Primary causes and molecular mechanisms of LNM are still largely unclear. We hypothesized that factors related with cancer progress and/or pr...

INTRODUCTION Elective neck dissection is recommended in cases of oral cavity squamous cell carcinoma without lymph node metastasis because of the risk of occult metastasis. OBJECTIVE The present study aimed to evaluate predictive factors for occult lymph node metastasis in patients with oral cavity squamous cell carcinoma treated with elective neck dissection and their impact on overall and d...

PURPOSE Many urban trauma centers have abandoned proximity arteriography, which is defined as exclusion arteriography used to evaluate the asymptomatic patient with penetrating extremity trauma near major arteries. However, decision analysis has not been applied to study proximity arteriography. MATERIALS AND METHODS The cost-effectiveness of proximity arteriography was examined by creating a...

BACKGROUND We sought to elaborate the epidemiology and outcomes of adult patients with occult Staphylococcus aureus bacteremia who were inadvertently discharged from the emergency department (ED) before positive blood culture results were obtained. METHODS Between 2001 and 2010, 759 true occult bacteremia cases were identified, including 65 patients with S. aureus bacteremia. Sixty-two patien...
