Background: Extremity injuries contaminated with petroleum products pose clinical dilemmas. This project was designed to evaluate the efficacy of a dioctyl sulfosuccinate (DS) solution for cleansing petroleum-contaminated skin.
Methods: One hundred Sprague-Dawley rats were subjected to a contamination protocol followed by a cleansing procedure. Four petroleum contaminants and five cleansing solutions were selected. The protocol consisted of shaving, initial punch biopsy, contamination, precleansing punch biopsy, standardized scrub protocol, and postcleansing punch biopsy. Biopsy samples were analyzed for petroleum residue using fluorometry.
Results: The 10% DS solution had the highest reduction of crude oil, grease, and tar: 99.6 +/- 0.4% (mean +/- SD) contaminant reduction for crude oil, 99.8 +/- 0.2% for grease, and 99.8 +/- 0.2% for tar. The other cleansers showed less efficacy (p < 0.05).
Conclusion: Concentrated DS appears to be significantly more effective at cleaning petroleum products from skin than the commonly chosen surgical and commercial cleansers.

Intravascular large B-cell lymphoma (IVLBCL) is characterized by clinical presentations described as B symptoms, consisting of fever, night sweats, and weight loss. Intravascular lymphomas are more frequently diagnosed in elderly patients and are challenging to diagnose because of their nonspecific clinical presentation. Malignant lymphomas are recognized as the leading cause of fever of unknown origin.

Objective: To assess the effectiveness of labial minor salivary gland biopsy (LSGB) alone or in combination with punch skin biopsy (SB) for the detection of amyloid deposits in hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN).
Methods: In this single-center retrospective study, Congo red staining of minimal invasive LSGB (4 mm) and SB (3 mm) was assessed in ATTRv-PN patients consecutively evaluated between 2012 and 2023.
Results: Histopathological data of 171 ATTRv-PN, including 49 early-onset p.

PGK1 (phosphoglycerate kinase-1) is required for ATP production in the body. Mutation in the PGK1 gene causes a rare, inherited metabolic disorder causing deficiency of enzyme PGK1, leading to hemolytic anemia, neurological symptoms, and muscle weakness. We generated induced pluripotent stem cells (iPSCs) from a patient carrying a PGK1 variant by isolating fibroblasts from skin punch biopsy and reprogramming using CytoTune iPS 2.

The capacity for tissue repair during wound healing declines with age. A chronic low but systemic inflammatory status, often called "inflammaging", is considered a key factor that contributes to impaired tissue regeneration. This phenomenon has been substantiated by an increased number of immune cells in wound-tissue of old mice.
