BACKGROUND Omitting extensive lymph node dissection could reduce esophagectomy morbidity in patients without lymph node metastases. Sentinel node biopsy may identify abdominal or thoracic lymph node metastases, thereby differentiating treatment. Feasibility of this approach was investigated in Western European esophageal cancer patients with advanced disease, without lymph node metastases at di...

The use of sentinel species shows the potential to bridge the gap between animal-based and human-based environmental health research. With regard to the assessment of environmental contamination, the use of the terms "indicator," "monitor," and "sentinel" has often been confusing and ambiguous. A set of definitions is proposed as a standard to rectify this situation. The advantages of the use o...

PRIMARY PURPOSE The staging of regional nodes by means of sentinel node detection has been shown to accurately detect subclinical nodal metastases from cutaneous melanoma. On the other hand, the oncological applications of 18F-fluoro-2-deoxy-D-glucose positron emission tomography (18FDG PET) are, nowadays, firmly established. However, the sensitivity of such metabolic imaging for staging the re...

CONTEXT Cutaneous melanoma presents significant morbidity and mortality. Nowadays, about 90% of them are diagnosed by clinical examination and most are localized melanomas. Sentinel node biopsy has brought about a new and interesting approach towards localized cutaneous melanoma. The meaning of micrometastases in sentinel nodes diagnosed by the reverse transcriptase-polymerase chain reaction is...

The sentinel node is the first lymph node that receives the lymph drainage from the primary tumour. The pathological status of the sentinel node should reflect the histopathology of the entire regional lymph drainage area--both vulvar and cervical cancer spread through the lymphatic system. In gynaecological oncology recent studies have confirmed the utility of the sentinel node concept in vulv...

AIM To show our experience using the portable gamma camera during surgery in the detection of the sentinel node in breast cancer. MATERIAL AND METHODS A total of 46 women diagnosed with breast cancer were included. This study was carried out by means of the periareolar intradermal injection. Planar images and SPECT/CT were acquired. On the following day, the sentinel nodes were localized intr...

BACKGROUND The purpose of this study was to present the feasibility of indocyanine green (ICG) mapping of sentinel lymph node in recurrent nasopharyngeal carcinoma (NPC). M1ETHODS: Peritumoral injection of 5-mg ICG solution and real-time mapping of the sentinel lymph nodes in the neck was performed during surgery. The sentinel lymph node identified was excised and sent separately for laboratory...

Monitoring of the human-induced changes and the availability of reliable and methodologically consistent urban area maps are essential to support sustainable urban development on a global scale. The Global Human Settlement Layer (GHSL) is a project funded by the European Commission, Joint Research Centre, which aims at providing scientific methods and systems for reliable and automatic mapping ...

BACKGROUND There are various methods for detecting sentinel lymph nodes in breast cancer. Sentinel lymph node biopsy (SLNB) using a vital dye is a convenient and safe, intraoperatively preparative method to assess lymph node status. However, the disadvantage of the dye method is that the success rate of sentinel lymph node detection depend on the surgeon's skills and preoperative mapping of the...

background & aims: mistyping either a donor or a recipient can lead to transfusion with abo incompatible blood which results in severe intravascular hemolysis and may even result in the death of the recipient. abo phenotype is one of the essential tests in immunohematology. eighty percent of blood group a and ab persons are subtype a1 and a1b, respectively. the other 20% of these blood groups a...
