A previously healthy 34-year-old female presented with a 5-month history of progressive backache and weakness in the left fingers. Magnetic resonance imaging (MRI) showed soft tissue masses in the spinal canal distributed along the nerve course. The patient's baseline laboratory data were normal. Surgical intervention was performed and histological examination identified isolated spinal granulocytic sarcoma (GS). A bone marrow biopsy also presented normal findings. However, the patient developed numbness and pain in the right lower limb two months later. Fluorodeoxyglucose (FDG)-positron emission tomography (PET) showed FDG uptake in the left trapezius muscle, cervix uteri, iliac bone, lymphadenectasis of the pelvic wall and left axillary fossa. Cerebrospinal fluid (CSF) examination allowed a diagnosis of central nervous system leukemia (CNSL). The patient underwent chemotherapy and intrathecal injection, resulting in the elimination of the residual lesion. Correct diagnosis and adequate treatment are essential to achieve optimal results in patients with isolated spinal GS.

Metagenomic next-generation sequencing for the clinical identification of spinal infection-associated pathogens.
Front Cell Infect Microbiol
January 2025
Department of Spine Surgery, Fuzhou Second General Hospital, Fuzhou, Fujian, China.
Background: This study aimed to evaluate the efficacy of metagenomic next-generation sequencing (mNGS) technology for identifying pathogens associated with spinal infection (SI).
Methods: A retrospective analysis was conducted on clinical data from 193 patients with suspected SI between August 2020 and September 2024. Based on histopathological results, the patients were divided into the SI group (n=162) and the non-SI group (n=31).

Department of Neurosurgery, National Hospital for Neurology and Neurosurgery, Queen Square, London, UK.
Objective: Neurosurgical care is difficult to access in many scenarios. Aeromedical evacuation of acutely unwell neurosurgical patients from remote, isolated or poorly equipped locations can be considered. This article aims to provide a framework of logistical factors which deserve special consideration in the preparation of these patients for transfer.

Background Context: On radiopathological examination of spinal tuberculosis (TB), two predominant forms are known: dry and wet types. Wet TB, as the name suggests, has abscess formation as its predominant presenting feature and is the exudative form; dry TB includes caseation and sequestration with minimal exudate. Dry TB often exhibits poorer recovery patterns than the wet counterparts, which can be possibly ascribed to vasculitis, ischemia, or tubercular myelitis, rather than isolated mechanical compression.

Department of Anesthesia, Jiaxing University Affiliated Women and Children Hospital, Jiaxing 314050, Zhejiang Province, PR China. Electronic address:
Background: While TRPA1 serves as a therapeutic target for nociceptive pain, its role in acute visceral pain induced by uterine cervical dilation (UCD) remains an enigma. This study aims to elucidate the upstream and downstream mechanisms of TRPA1 in the context of UCD-induced acute visceral pain.
Methods: The UCD rats were administered with SAH (inhibitor of the METTL3-METTL14 complex) via intrathecal tubing.
