Panton-Valentine leucocidin is a major virulence factor produced by some strains of Staphylococcus aureus (SA-PVL). The best-described invasive infection is a necrotizing haemorrhagic pneumonia. Pleural effusion is not uncommon but is always associated with a parenchymal lesion. Here, we report a case of haemorrhagic pleurisy attributable to isolated SA-PVL.

Introduction: Two-stage revision is considered the gold standard treatment in chronic periprosthetic joint infection (PJI) but no specific criteria or examination exist to determine infection eradication before reimplantation. This study aimed to assess the diagnostic performance of leukocyte scintigraphy after the first-stage procedure in two-stage revision for chronic PJI.
Material And Methods: Patients studied with leukocyte scintigraphy after cement spacer insertion for knee PJI from January 2012 to December 2021 were retrospectively included.

Background: Chordoma is a slow-growing, primary malignant bone tumor that arises from notochordal tissue in the midline of the axial skeleton. Surgical excision with negative margins is the mainstay of treatment, but high local recurrence rates are reported even with negative margins. High-dose radiation therapy (RT), such as with proton or carbon ions, has been used as an alternative to surgery, but late local failure remains a problem.

Objective: The duration of viral shedding and criteria for de-isolation in the hospital among immunocompromised patients with coronavirus disease 2019 (COVID-19) remain unclear. This study aimed to evaluate viral shedding duration in immunocompromised patients infected with the Omicron variant of severe acute respiratory syndrome coronavirus 2.
Methods: A prospective cohort study was performed at 2 tertiary medical centers in Japan during the Omicron epidemic waves from July 2022 to January 2023.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.

Background: The recovery of injured peripheral nerves relies on angiogenesis, where newly formed blood vessels act as pathways guiding Schwann cells across the wound to support axon regeneration. While some research has examined this process, the specific mechanisms of angiogenesis in peripheral nerve healing remain unclear. In vitro models are vital tools to investigate these mechanisms; however, no current in vitro culture methods exist for isolating vascular cells, such as endothelial cells (ECs) and pericytes, specifically from sciatic nerves.
