BACKGROUND Sentinel surveillance for HIV among women attending antenatal clinics using unlinked anonymous testing is a cornerstone of HIV surveillance in sub-Saharan Africa. Increased use of routine antenatal HIV testing allows consideration of using these programmatic data rather than sentinel surveillance data for HIV surveillance. METHODS To gauge Kenya's readiness to discontinue sentinel ...
OBJECTIVE Relatively minor abusive injuries can precede severe physical abuse in infants. Our objective was to determine how often abused infants have a previous history of "sentinel" injuries, compared with infants who were not abused. METHODS Case-control, retrospective study of 401, <12-month-old infants evaluated for abuse in a hospital-based setting and found to have definite, intermedia...
ii Faculty The objective of this course is to teach the indications, techniques, and theoretical concepts of lymphatic mapping and sentinel node biopsy for breast cancer and melanoma. After participating in this course, surgeons should be able to begin to perform and evaluate lymphatic mapping and sentinel node biopsy with blue dye, radio-isotope, or a combination of both. The histopathologic m...
INTRODUCTION Sentinel node mapping has been used for laryngeal carcinoma in several studies, with excellent results thus far. In the current study, we report our preliminary results on sentinel node mapping in laryngeal carcinoma using intra-operative peri-tumoral injection of a radiotracer. MATERIALS AND METHODS Patients with biopsy-proven squamous cell carcinoma of the larynx were included ...
BACKGROUND Sentinel node navigation surgery is gaining popularity in oral cancer. We assessed application of sentinel lymph node navigation surgery to pharyngeal and laryngeal cancers by evaluating the combination of contrast-enhanced ultrasonography and indocyanine green fluorescence in animal models. METHODS This was a prospective, nonrandomized, experimental study in rabbit and swine anima...
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...
BACKGROUND Sentinel lymph node biopsy has been established as the preferred method for staging early breast cancer. A prior history of mastectomy is felt to be a contraindication. CASE PRESENTATION A patient with recurrent breast cancer in her skin flap was discovered to have positive axillary sentinel nodes by sentinel lymph node biopsy five years after mastectomy for ductal carcinoma in sit...
*Research care, active lifestyle community with sentinel sites: a new approach in health research system
UNLABELLED Paraaortic sentinel node biopsy may be a challenging procedure because the sentinel nodes are located retroperitoneally in close proximity to vital structures. The purpose of this study was to describe and evaluate the value of preoperative SPECT/CT for lymphatic mapping, and a portable gamma-camera for intraoperative radioguidance, in patients with paraaortic sentinel nodes. METHO...
Background. Most institutions require a patient undergoing sentinel lymph node biopsy to go through nuclear medicine prior to surgery to be injected with radioisotope. This study describes the long-term results using intraoperative injection of radioisotope. Methods. Since late 2002, all patients undergoing a sentinel lymph node biopsy at the Yale-New Haven Breast Center underwent intraoperativ...
