PURPOSE To evaluate the potential of brilliant blue G (BBG) for intraoperative staining of the inner limiting membrane (ILM) with respect to staining properties and surgical outcome. METHODS In a retrospective, non-comparative clinical case series, we analysed 17 consecutive chromovitrectomy interventions for surgery of macular holes, ERMs, vitreoretinal(More)
PURPOSE To evaluate the potential of brilliant blue G (BBG) and indocyanine green (ICG) for intraoperative staining of the internal limiting membrane (ILM) with respect to perceivable contrast. METHODS In a retrospective clinical case series the authors analyzed 26 consecutive chromovitrectomy interventions in 26 patients with macular holes, epiretinal(More)
Current guidelines recommend the assessment of at least 12 lymph nodes for rectal cancer staging. Preoperative chemoradiotherapy may affect lymph node yield in this malignancy. This study investigated the impact of neoadjuvant chemoradiotherapy on the number of lymph nodes retrieved from rectal cancer patients. An analysis of 162 rectal cancer patients who(More)

METHODS Fifty-four patients with cancer of the oral cavity and oropharynx were randomly assigned to rinse the oral cavity in an oil solution containing either VE or placebo before every conventional(More)
PURPOSE External irradiation followed by intracavitary therapy (EBIC) has been considered the standard treatment for stage III-B cancer of the uterine cervix. For different reasons, some patients are not suited for intracavitary therapy (ICT), and the treatment may be given entirely by external beam irradiation alone (EBRTA). The purpose of our study is to(More)
e15560 Background: The cisplatin/irinotecan doublet plus concomitant radiation therapy has been tested in phase II studies as a non-infusional alternative for the treatment of locally advanced esophageal squamous cell carcinoma (ESCC), showing good antitumoral activity and acceptable safety profile. Here, we describe our institutional experience with this(More)
Urban mobility problems affects the vast majority of cities nowadays. Thus, systems that provide real time information to assist in planning routes and choosing the most appropriate paths are essential to make transport more effective. As an alternative solution to problems related to mobility in cities, there are the so-called Intelligent Transportation(More)
The authors report a case of right ventricle endomyocardial fibrosis in a 6-year-old boy. Particular attention is paid to the discussion of the new methods for diagnosing and treating these conditions, namely echocardiography, endomyocardial biopsy and surgery.
