Intraoperative methylene blue staining is effective as a single mapping technique in the identification of sentinel lymph nodes in dogs with low-grade mast cell tumours.
J Small Anim Pract
January 2025
Department of Veterinary Medical Sciences, University of Bologna, Bologna, Italy.
Objectives: The aim of this prospective study was to assess the association between methylene blue staining pattern and the presence of histologic nodal metastasis in dogs with low-grade mast cell tumour in low-resource settings for the efficient diagnosis of lymphatic spread.
Methods: Dogs with a single, cytologically low-grade mast cell tumour and no documented distant metastases were prospectively included and underwent surgery. Along with primary mast cell tumour removal, intraoperative sentinel lymph node mapping with peritumoral mast cell tumour injection and regional lymph node excision, regardless of whether blue dye was visible in the lymph node, were performed.
Alternative approaches for monitoring and evaluation of lymphatic filariasis following mass drug treatment with ivermectin, diethylcarbamazine and albendazole in East New Britain Province, Papua New Guinea.

Department of Pathology, Center for Global Health and Disease, Case Western Reserve University, Cleveland, Ohio, United States of America.
Background: WHO recommends two annual rounds of mass drug administration (MDA) with ivermectin, diethylcarbamazine, and albendazole (IDA) for lymphatic filariasis (LF) elimination in treatment naïve areas that are not co-endemic for onchocerciasis such as Papua New Guinea (PNG). Whether two rounds of MDA are necessary or sufficient and the optimal sampling strategies and endpoints for stopping MDA remain undefined.
Methods And Findings: Two cross-sectional studies were conducted at baseline (N = 49 clusters or villages) and 12 months after mass drug administration (MDA) with IDA (N = 47 villages) to assess lymphatic filariasis (LF) by circulating filarial antigenemia (CFA) and microfilariae (Mf).
The Patent Blue V Paradox: Hidden Offender, Serial Culprit.
Dermatitis
January 2025
From the Department of Allergy and Clinical Immunology, Unidade Local de Saúde de São João, Porto, Portugal.
Patent Blue V (PBV) is extensively used in sentinel lymph node identification in cancer surgery, potentially leading to an increased incidence of hypersensitivity reactions. A retrospective analysis was conducted on patients with suspected PBV hypersensitivity, at our center from 2010 to 2023. Skin prick tests (SPT) were performed on all patients, followed by intradermal tests (IDT) if SPT was negative.

Curr Opin Oncol

Department of Medical Oncology, Institut Jules Bordet - Université Libre de Bruxelles (ULB).
Purpose Of Review: This review aims to explore the evolving management strategies for stage III melanoma, focusing on the comparative effectiveness of traditional surgical approaches like complete lymph node dissection (CLND) versus modern adjuvant therapies. It also examines the latest evidence on the efficacy, risks, and complications of these strategies, emphasizing the role of shared decision-making between patients and clinicians.
Recent Findings: Recent clinical trials and meta-analyses, including the MSLT-II and DeCOG-SLT studies, have demonstrated that CLND may not significantly improve survival outcomes in melanoma patients with sentinel lymph node biopsy (SLNB)-positive status.
Impact of molecular diagnostic techniques on the acute respiratory infection sentinel surveillance program, Antioquia, Colombia, 2022.
Front Epidemiol
January 2025
GHI One Health Colombia, Universidad Nacional de Colombia, Medellín, Colombia.
Objectives: Surveillance of acute respiratory infection (ARI) informs vaccination, preventive, and management decisions. In many countries, immunofluorescence is the cornerstone for ARI surveillance. We aimed to determine the effect of adding multiplex polymerase chain reaction (mPCR) to conventional surveillance in ARI.
