BACKGROUND: Metastatic involvement of the sentinel lymph node (SLN) represents a key prognostic factor in melanoma. The combined use of a radiocolloid (technetium-99m) and blue dye is the gold standard in sentinel lymph node biopsy (SLNB). In this context, near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) has been suggested as an alternative. The objective of the present study was to examine the potential advantages of fluorescence-guided SLNB - compared to the conventional method - with respect to the visualization of lymphatic drainage pathways and the SLN...

HINTERGRUND: Der Nachweis metastatischer Infiltrate im Sentinel-Lymphkoten (SLN) gilt als wesentlicher prognostischer Faktor des Melanoms. Alternativ zur Farbstoffmethode mit Patentblau zum Goldstandard der SLN-Biopsie (SLNB) mittels Radiokolloid wird die fluoreszenzoptische Darstellung mit Hilfe von Indocyaningrün (ICG) und Nahinfrarot (NIR)-Kamerasystem kommuniziert. Im Vergleich zur konventionellen Methode wurde die Wertigkeit des ICG-/NIR-Verfahrens in Abhängigkeit vom Body-Mass-Index (BMI) des Patienten und der Konzentration von ICG bezüglich der Visualisierung des Lymphabstroms und des SLNs untersucht...

Management of breast cancer is based on national and international guidelines. These are defined on evidence-based medicine. The main purpose of this review is to compare the different guidelines for sentinel lymph node biopsy and completion axillary dissection after positive sentinel lymph node biopsy. This review of breast cancer guidelines led to identify consensus, but in some specific situations, they differ. The guidelines cannot be applied to all clinical cases, mandatoring multidisciplinary meetings are essential...

BACKGROUND: The inability to visualize the patient and surgical site directly, limits the use of current near infrared fluorescence-guided surgery systems for real-time sentinel lymph node biopsy and tumor margin assessment. METHODS: We evaluated an optical see-through goggle augmented imaging and navigation system (GAINS) for near-infrared, fluorescence-guided surgery. Tumor-bearing mice injected with a near infrared cancer-targeting agent underwent fluorescence-guided, tumor resection...

PURPOSE: The timing of sentinel lymph node biopsy (SLNB) in the context of neoadjuvant systemic therapy (NAST) in breast cancer is still controversial. SLNB before NAST has been evaluated in few single-institution studies in which axillary lymph node dissection (ALND), however, was commonly not performed in case of a negative SLNB. We investigated the potential clinical relevance of SLNB before NAST by performing ALND in all patients after NAST. METHODS: This national multicenter trial prospectively enrolled clinically node-negative breast cancer patients planned for NAST at 13 recruiting Swedish hospitals between October 2010 and December 2015...

Marine echinoderms are filter-feeding invertebrates widely distributed along the coasts, and which are therefore extensively exposed to anthropogenic xenobiotics. They can serve as good sentinels for monitoring a large variety of contaminants in marine ecosystems. In this context, a multi-residue analytical method has been validated and applied to Holothuria tubulosa specimens and marine sediments for the determination of 36 organic compounds, which belong to some of the most problematic groups of emerging and priority pollutants (perfluoroalkyl compounds, estrogens, parabens, benzophenones, plasticizers, surfactants, brominated flame retardants and alkylphenols)...

BACKGROUND: To limit the potential short and long-term morbidity of lymphadenectomy, sentinel lymph node (SLN) biopsy has been proposed for endometrial cancer. The principle of SLN biopsy relies on removal of a small number of lymph nodes that are the first drainage basins from a tumor and thus the most likely to harbor tumor cells. While the procedure may reduce morbidity, efficacy data is limited and little is known about how commonly the procedure is performed. OBJECTIVE: We examined the patterns and predictors of use of SLN biopsy and outcomes of the procedure in women with endometrial cancer who underwent hysterectomy...

We present a case of a patient who took part in a prospective sentinel lymph node (SN) study to investigate the drainage pattern from renal tumors. The patient was treated with laparoscopic radical nephrectomy (LRN), SN and non-SN lymph node dissection (LND) for a clinically node negative (cN0) left renal tumor of 6 cm (cT1b). Histopathological examination revealed a papillary type 2 pT1b renal cell carcinoma (RCC) with two para-aortic metastatic SNs (pN1). No adjuvant treatment was applied. The patient is free of disease at 63 months after surgery...

Immobilized preys are routinely used in agro-ecological exposure studies to quantify predation of pests under field conditions, but this method has not been validated. Our purpose was to determine the validity of using immobilized adults of the major rice pest Nilaparvata lugens, brown plant hopper (BPH), as sentinels. We used direct observation by video recording to determine the causal agents of removal of field exposed BPH sentinels with two experiments: 1) we recorded removal events of dead, immobilized BPH; and 2) we compared removal of (i) dead, immobilized BPH, (ii) live, immobilized BPH, and (iii) live, mobile BPH...

Rodent health-monitoring programs based on sampling an IVC system's exhaust air dust (EAD) has enhanced and evenreplaced traditional sentinels for some rodent pathogens. EAD testing by qPCR assay is an optimal surveillance methodfor the rapid detection of Corynebacterium bovis-infected immunodeficient mice. Here we demonstrate that an active EADsurveillance program for C. bovis can be used to maintain nude mice C. bovis-free after the transition from historically enzootically infected colonies. During 3 events over 3 y, rapid detection of infection, elimination of infected mice, aggressivequarantine measures, and local decontamination prevented the spread of C...

INTRODUCTION: Identification of lymph nodes and pathological analysis is crucial for the correct staging of colon cancer. Lymph nodes that drain directly from the tumor area are called "sentinel nodes" and are believed to be the first place for metastasis. The purpose of this study was to perform sentinel node mapping in vivo with indocyanine green and ex vivo with methylene blue in order to evaluate if the sentinel lymph nodes can be identified by both techniques. METHODS: Patients with colon cancer UICC stage I-III were included from two institutions in Denmark from February 2015 to January 2016...

Nontyphoidal Salmonella (NTS) gastroenteritis is a widespread global foodborne disease. To identify the epidemiologic characteristics, sources of food contamination, and risk factors of NTS gastroenteritis, epidemiologic data and stool specimens of diarrheal patients were collected from sentinel hospitals in Baoshan, Shanghai, People's Republic of China, between 2010 and 2014. Food products from nearby farmers' markets and animal feces from live poultry markets and livestock farms were sampled to identify the pathogen; a case-control study was conducted to characterize risk factors of NTS gastroenteritis...

Chlamydia trachomatis (CT) infections are not reportable in Germany and limited data on prevalence are available. CT screening has been offered free of charge to pregnant women since 1995 and to all women under 25 years since 2008. For symptomatic women and men, diagnostic testing is covered by statutory health insurance. We describe the establishment of a nationwide, laboratory-based, voluntary sentinel that electronically collects information on all performed CT tests with test results, test reason and patient information...

Using a test-negative design, the Canadian Sentinel Practitioner Surveillance Network (SPSN) assessed interim 2016/17 influenza vaccine effectiveness (VE) against dominant influenza A(H3N2) viruses considered antigenically matched to the clade 3C.2a vaccine strain. Sequence analysis revealed substantial heterogeneity in emerging 3C.2a1 variants by province and over time. Adjusted VE was 42% (95% confidence interval: 18-59%) overall, with variation by province. Interim virological and VE findings reported here warrant further investigation to inform potential vaccine reformulation...

Tobacco smoke exposure has been associated with risk of childhood acute lymphoblastic leukemia (ALL). Understanding the relationship between tobacco exposures and specific mutations may yield etiologic insights. We carried out a case-only analysis to explore whether prenatal and early-life tobacco smoke exposure influences the formation of leukemogenic genomic deletions. Somatic copy-number of 8 genes frequently deleted in ALL (CDKN2A, ETV6, IKZF1, PAX5, RB1, BTG1, PAR1 region, and EBF1) was assessed in 559 pre-treatment tumor samples from the California Childhood Leukemia Study...
