The measures of the blood loss prophylaxis and compensation, occurred at the time of 4350 surgical interventions on vertebral column conduction in 2697 patients with scoliosis, are analyzed. While performing osteoplastic fixation of vertebral column the blood loss have constituted 1200-2600 ml. The lowering of the blood loss down to 200-120 ml while conducting of complex correcting interventions was permitted by application of the governed hypotension together with general anesthesia.

Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Multifaceted approach to evacuating multi-level premacular hemorrhage in a case of suspected Valsalva retinopathy - a case report.

BMC Ophthalmol

January 2025

Department of Retina and Vitreous, Narayana Nethralaya, #121/C, 1st R Block, Chord Road, Rajaji Nagar, Bengaluru, Karnataka, 560010, India.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.

Methods: This is a retrospective interventional case report.

Background: Subarachnoid hemorrhage (SAH) remains a serious public health problem worldwide, especially in economically developed regions/countries. This study intends to thoroughly analyze the incidence, mortality, and disability-adjusted life years (DALYs) rate of SAH at the global, regional, and national levels. This study focused on the differences in SAH incidence between China and Japan from 1990 to 2019, and projected global, Chinese, and Japanese SAH incidence rates until 2030.

ZIC1 is a context-dependent medulloblastoma driver in the rhombic lip.

Nat Genet

January 2025

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, Ontario, Canada.

Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).
