Updates and controversies in contemporary grading of clear cell renal cell carcinoma and papillary renal cell carcinoma

Histopathology, EarlyView.
New concepts, innovations and some issues have emerged since the adoption a decade ago of WHO/ISUP grading for CCRCC and PRCC. Continued use of the WHO/ISUP grading for CCRCC and PRCC has been upheld by newer studies, and practice guidance for some of the grading issues, where data are available, is provided.

Spectrum of intrathoracic malignancies in children, a challenging entity

The Journal of Association of Chest Physicians
Paediatric thoracic malignancies are always a diagnostic challenge. In this case series, we report eight cases of malignancies in the paediatric age group. Case 1: A 13-year-old female presented with an anterior mediastinal mass. Computed tomography scan

UK recommendations for Ki‐67 immunohistochemical staining and interpretation in breast cancer

Histopathology, EarlyView.
Where possible, a validated digital imaging system should be utilized. If this is not available, then intermediate scores (5%–30%) should be thoroughly assessed using the Ki‐67 International Working Group guidance. Difficult cases should be double scored.

Poorly differentiated lung adenocarcinomas with concurrent ALK and CD30 expression: a diagnostic pitfall mimicking ALK‐positive anaplastic large‐cell lymphoma

Histopathology, EarlyView.
Poorly differentiated lung adenocarcinomas with concurrent anaplastic lymphoma kinase (ALK) and CD30 expression closely mimic ALK‐positive anaplastic large‐cell lymphoma, creating a significant diagnostic pitfall. Accurate classification requires comprehensive integration of clinical, radiologic, morphologic, immunophenotypic and molecular findings ...

Life‐stage variation in Sable Shearwater (Ardenna carneipes) physiology assessed using proteomics

Ibis, EarlyView.
Life‐stage transitions in seabirds involve substantial shifts in physiological demands, yet the molecular mechanisms underpinning these changes remain poorly resolved. Here we applied untargeted data‐independent acquisition mass spectrometry (DIA‐MS) to characterize and compare the plasma proteomes of fledgling and adult Sable Shearwaters Ardenna ...

Soft‐Tissue Augmentation During Implant Placement in the Aesthetic Zone: Clinical, Radiographic, Histological and Patient‐Reported Outcomes From a Randomised Controlled Trial Using Connective Tissue Graft and a Volume‐Stable Collagen Matrix

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To evaluate the clinical, radiographic, histological and patient‐reported outcome measures (PROMs) of soft‐tissue augmentation (STA) during implant placement in the aesthetic zone using a connective tissue graft (CTG) or a volume‐stable collagen matrix (VCMX). Materials and Methods In this three‐arm randomised controlled trial, 25 patients

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

Journal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Platelet‐Rich Fibrins as Local Drug‐Delivery Carriers

Journal of Periodontal Research, EarlyView.
Autologous platelet concentrates (APCs), particularly platelet‐rich fibrin (PRF), act as biologically active fibrin scaffolds, capable of entrapping and gradually releasing therapeutic agents in oral and periodontal therapy. The incorporation of bioactive compounds, such as antibiotics, antifungals, vitamins, antidiabetic drugs, and exosomes, enhances ...

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

Oral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...
