This study presents a patient who died of acute renal failure (ARF) as a complication of scleroderma. The patient remained normotensive throughout the clinical course. Myeloperoxidase-anti-neutrophil cytoplasmic antibody was negative. Autopsy revealed fibrin thrombi in the glomerular capillaries and afferent arterioles, mesangiolysis, and double contour of the glomerular basement membrane. Contrarily, "onionskin lesions" of renal interlobular arteries, the histological hallmark of scleroderma renal crisis, were not discovered. These findings suggested that thrombotic microangiopathy (TMA) was the cause of ARF. Although the frequency is not high, close monitoring should be given to TMA in scleroderma because of possible mortality.

Guy's & St Thomas' Hospital, Department of Critical Care & Nephrology, London, UK.
Objectives: To describe the clinical presentation and clinicopathological findings of dogs with nodular splenic lesions composed of heterogeneous cell components associated with systemic inflammation and to provide information on the outcome after surgical resection.
Materials And Methods: Medical records were searched for dogs with histologically and immunohistochemically characterised nodular splenic lesions with mixed stromal, histiocytic and lymphoid cells and the presence of systemic inflammatory markers at the time of diagnosis.
Results: Four dogs were included, of which three had an undifferentiated splenic stromal sarcoma and one had a splenic leiomyosarcoma.

Department of Urology, Renmin Hospital of Wuhan University. Wuhan, Hubei Province, PR China. Electronic address:
Background: Renal ischemia-reperfusion injury (IRI) is a prevailing manifestation of acute kidney injury (AKI) with limited treatment options. TRIM44 has emerged as a possible target for treatment due to its regulatory function in inflammatory pathways.
Methods: In vivo and in vitro models were employed to ascertain the TRIM44 impact on renal IRI.
The variable relationship between the National Early Warning Score on admission to hospital, the primary discharge diagnosis, and in-hospital mortality.
Intern Emerg Med
January 2025
Department of Renal Medicine, Northern Care Alliance, Salford Royal Hospital, Salford, M6 8HD, UK.
Background: Patients with an elevated admission National Early Warning Score (NEWS) are more likely to die while in hospital. However, it is not known if this increased mortality risk is the same for all diagnoses. The aim of this study was to determine and compare the increased risk of in-hospital mortality associated with an elevated NEWS and different primary discharge diagnoses in unselected emergency admissions to a UK university teaching hospital.

Department of Neuro-Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.
Background: Neurologic symptoms seen in patients receiving immune checkpoint inhibitors (ICI) may not be entirely caused by immunotoxicity. We aim to highlight these confounding conditions through clinical cases to encourage early recognition and management.
Methods: We describe a series of seven cases from our institution that were treated with ICI and presented with Neurologic symptoms and were diagnosed with superimposed conditions beyond immunotoxicity.
