A novel posterior decompression technique (anterior sliding decompression osteotomy) for beak-type ossification of the posterior longitudinal ligament in the thoracic spine.
J Neurosurg Spine
January 2025
3Department of Orthopedic Surgery, Haeundae Bumin Hospital, Busan, South Korea.
Objective: Conventional decompression surgery for beak-type ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine, whether approached anteriorly or posteriorly, poses several challenges, including technical complexity, cerebrospinal fluid leakage, incomplete decompression, and potential neurological deterioration. Therefore, the authors introduce a novel technique, anterior sliding decompression osteotomy (ASDO), for thoracic myelopathy caused by OPLL and evaluate the efficacy and safety of this technique.
Methods: Six patients (4 men and 2 women) who underwent ASDO surgery for beak-type OPLL in the thoracic spine with a follow-up period of at least 2 years were included in the cohort.
Rare Neoplastic Meningitis in Cerebellar Medulloblastoma Detected by PET/CT.
Clin Nucl Med
January 2025
From the Department of Nuclear Medicine, University of Health Sciences, Prof. Dr. Cemil Taşcıoğlu City Hospital, Istanbul, Turkey.
Neoplastic meningitis, also known as leptomeningeal metastases, is a rare clinical entity seen in less than 1%-2% of primary nervous system tumors. Diagnosis of leptomeningeal metastases is difficult and is achieved by cytologic evidence of malignant cells in cerebrospinal fluid, or demonstration of radiologic abnormality. 18F-FDG PET/CT can detect leptomeningeal metastases before anatomical changes.

Translational Brain Science, Department of Metabolism and Systems Science, College of Medicine and Health, University of Birmingham, Birmingham, UK.
Objective: To gain initial insight into the efficacy to lower intracranial pressure (ICP), side effects, and effects on cognition of five drugs commonly used to treat idiopathic intracranial hypertension (IIH).
Background: Limited clinical data exist for the treatment for IIH. Impaired cognition is recognized in IIH and can be exacerbated by medications.
Paracetamol, its metabolites, and their transfer between maternal circulation and fetal brain in mono- and combination therapies.
Pharmacol Rep
January 2025
Department of Neuroscience, School of Translational Medicine, Monash University, Melbourne, VIC, 3004, Australia.
Background: Due to its availability and perceived safety, paracetamol is recommended even during pregnancy and for neonates. It is used frequently alone or in combination with other drugs required for the treatment of various chronic conditions. The aim of this study was to investigate potential effects of drug interactions on paracetamol metabolism and its placental transfer and entry into the developing brain.

Quantitative measurement of metabolites is essential to understand biological and disease processes. Absolute quantification by spiking heavy isotope-labeled internal standards and analyzing on mass spectrometry (MS) platform is a key method to determine the concentration of metabolites in biological samples. However, MS-based absolute quantification is often challenged by the commercial availability and high costs of isotope-labeled internal standards.
