We must take special care when treating postoperative fluid accumulation around breast implants (BIs) to exclude any serious complications, including BI-associated anaplastic large cell lymphoma. However, most late-onset fluid accumulation is caused by other conditions, such as traumatic hematoma and residual postoperative seroma. Surgeons must choose whether to conservatively observe or remove such BIs, while also determining whether to perform partial capsulectomy or total capsulectomy to solve the problem of fluid accumulation.

Article Synopsis
  • Adult non-neoplastic hyperinsulinemic hypoglycemia (ANHH) is a rare condition in adults caused by increased insulin production due to diffuse hyperplasia of pancreatic endocrine cells, diagnosed through pathological examination.
  • A quantitative study was conducted measuring various characteristics of pancreatic islets in ANHH patients and controls, including islet shape, cell size, and the presence of nucleoli in cells, using NIS-Elements software and evaluating interobserver agreement among pathologists.
  • The study found that ANHH specimens had islets with lower circularity (more irregular shapes) and a higher percentage of cells with recognizable nucleoli compared to controls, but overall diagnosis accuracy among experienced and less-experienced pathologists was similar and relatively

Signaling lymphocytic activation molecule family member 8 (SLAMF8) / B-lymphocyte activator macrophage expressed/CD353 is a member of the CD2 family. SLAMF8 suppresses macrophage function but enhances the growth of neoplastic mast cells via SHP-2. In this study, we found that some anaplastic large cell lymphoma (ALCL) samples were immunohistochemically positive for SLAMF8.

A periodic mesoporous organosilica (PMO) containing 2,2'-bipyridine (bpy) ligands within the framework (BPy-PMO) has great potential for designing novel catalysts by modifying metal complexes. A photosensitizing site (Ru(PS)) was introduced by treating cis-[Ru(bpy) (dimethylsulfoxide)Cl]Cl with BPy-PMO. Then a catalytic site (Ru(Cat)) was brought in Ru(PS) -BPy-PMO by reaction with a ruthenium polymer [Ru(CO) Cl ] .
