Methods： From December 2003 to May 2004, a crosssectional study was conducted to investigate demographic characteristics, sexual behaviors, condom use, and knownHIV status among HIV-positive commercial blood donors.A total of 796 subjects were recruited for the study. Results： Of the 796 study subjects, 53.0% （258/487） did not use condoms, 10.9% （53/487） inconsistently usedcondoms, and 36.1% （176/487） consistently used condoms with a steady sex partner in the past threemonths. Age （OR, 0.57; 95% CI： 0.39, 0.82）, years of education （OR, 1.90; 95% Ch 1.27, 2.84） and known HIVstatus （OR, 1.66; 95% CI： 1.12, 2.45） were independently and positively associated with condom use with a steady sex partner. Of those subjects without a steady sexual partner in the past year, 63.6% （14/22） did not use condoms, 9.1% （2/22） inconsistently used condoms, and 27.3% （6/22） consistently used condoms. Conclusion： HIV counseling and education should be focused on HIV-positive blood donors to prevent a secondary spread of HIV through unsafe sexual practices.展开更多

Although not as well studied or characterized as pancreatic adenocarcinorna there are many distinct lesions which exhibit diverse biological behaviors and varying degrees of malignancy. These lesions include： endocrine neoplasms, cystic tumors, solid pseudopapillary tumors, acinar cell carcinoma, squamous cell carcinoma, primary lymphoma of the pancreas, and metastatic lesions to the pancreas. These less common neoplasms are being diagnosed more frequently as the number and sensitivity of diagnostic imaging studies increase. This review article discusses the clinical course, diagnosis, and treatment of these less common, but quite relevant, neoplasms of the pancreas.展开更多

An accurate diagnosis is necessary for the optimal management of perianal lesions. Treatment of perianal Crohn's disease includes medical and/or surgical options. Recent discoveries in the pathogenesis of this disease have led to advances in medical and surgical therapy with good results. Perianal lesions in Crohn's disease remain a challenging aspect for both gastroenterologists and surgeons and lead to a greatly impaired quality of life for all patients affected by this disease. A multidisciplinary approach is mandatory to obtain the best results.展开更多
