malignant papillary neoplasms of the breast comprise a number of microscopically distinct lesions, where apocrine metaplasia is commonly found in papillomas compared to other papillary lesions including papillary carcinomas. however, association of apocrine metaplasia in papilloma with ductal carcinoma in situ (dcis) is not very well defined. the lesions with apocrine metaplasia are not only di...

Lesion movement during positron emission tomography (PET) scan acquisition due to normal respiration is a common source of artefact. A PET scan is acquired in multiple couch positions of between 2 and 5 min duration with the patient breathing freely. A PET-avid lesion will become blurred if affected by respiratory motion, an effect similar to that created when a person moves in a photograph. Th...

UNLABELLED Hybrid PET/CT was compared with PET alone in the staging and restaging of patients with Ewing tumor to assess the benefit of the combined imaging technique. METHODS A total of 163 (18)F-FDG PET/CT studies performed in 53 patients (age: range, 4-38 y; median, 16.5 y) with histopathologically confirmed Ewing tumor were evaluated retrospectively. All PET/CT studies included low-dose C...

scopic surgery) is currently of greatest interest to endoscopists and laparoscopic surgeons [1–3]. Early gastric cancer (EGC) is generally managed with endoscopic submucosal resection (ESD) if indicated. We present a case of EGC removed by hybrid NOTES, with a concomitant colon cancer resected via laparoscopic colectomy. A 62-year-old man was diagnosed with simultaneous gastric and colonic canc...

Lipid-based nanocarriers have been extensively investigated for drug delivery due to their advantages including biodegradability, biocompatibility, nontoxicity, and nonimmunogenicity. However, the shortcomings of traditional lipid-based such as insufficient targeting, capture by reticuloendothelial system, fast elimination limit efficiency therapeutic efficacy. Therefore, a series multifunction...

BACKGROUND The appropriate management of women with minor cytologic lesions in their cervix is unclear. We performed a meta-analysis to assess the accuracy of human papillomavirus (HPV) DNA testing as an alternative to repeat cytology in women who had equivocal results on a previous Pap smear. METHODS Data were extracted from articles published between 1992 and 2002 that contained results of ...

Background. Persistent infection with high-risk human papillomavirus (HR-HPV) has been demonstrated to be the necessary causal factor for developing cervical cancer. To know the most prevalent HR-HPV in different geographical areas is important to design diagnostic tests and implementation of vaccines. Objectives. The goal of this study is to evaluate the prevalence of HR-HPV in a total of 1001...
