Risk factors for hidden blood loss in unilateral biportal endoscopic lumbar interbody fusion : a single-center retrospective study.

Background: Hidden blood loss (HBL) is often ignored unilateral biportal endoscopic interbody fusion surgery (ULIF). We investigated the amount and influencing factors of HBL in ULIF surgery in this study.

Methods: From October 2020 to November 2023, 100 patients' clinical and radiological data were retrospectively analyzed.

Comparison of the total and hidden blood loss in patients undergoing single-level open and unilateral biportal endoscopic transforaminal lumbar interbody fusion: a retrospective case control study.

Purpose: This study aimed to compare total blood loss (TBL) and hidden blood loss (HBL) in patients undergoing single-level open transforaminal lumbar interbody fusion (O-TLIF) and unilateral biportal endoscopic transforaminal lumbar interbody fusion (ULIF).

Methods: A total of 53 patients who underwent ULIF and 53 patients who underwent O-TLIF from March 2020 to July 2022 were retrospectively reviewed. The Nadler's formula was employed to estimate the patient's blood volume (PBV), Gross's formula to estimate TBL, and Sehat's formula to estimate HBL.

Melatonin attenuated chronic visceral pain by reducing Na1.8 expression and nociceptive neuronal sensitization.

Background: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder, and its specific pathogenesis is still unclear. We have previously reported that TTX-resistant (TTX-R) sodium channels in colon-specific dorsal root ganglion (DRG) neurons were sensitized in a rat model of visceral hypersensitivity induced by neonatal colonic inflammation (NCI). However, the detailed molecular mechanism for activation of sodium channels remains unknown.

Clinical comparison of three-dimensional exoscope vs. operative microscope in transforaminal lumbar interbody fusion: A retrospective case-control study.

Purpose: Here, we sought to determine the safety and feasibility of three-dimensional exoscope (3D EX). We compared data on surgery, complications, postoperative drainage, hematology, and clinical outcomes in the group that underwent transforaminal lumbar interbody fusion (TLIF) using an operative microscope (OM) relative to those treated using 3D EX.

Methods: We retrospectively reviewed records on 74 patients who underwent one- or two-level TLIF from August 2019 to October 2020.

Retinoic Acid Receptor Gamma (RAR) Promotes Cartilage Destruction through Positive Feedback Activation of NF-B Pathway in Human Osteoarthritis.

Osteoarthritis (OA) is a severe inflammation-related disease which leads to cartilage destruction. The retinoic acid receptor gamma (RAR) has been indicated to be involved in many inflammation processes. However, the role and mechanism of RAR in cartilage destruction caused by inflammation in OA are still unknown.

A new method for establishing operative channels in unilateral biportal endoscopic surgery: Technical notes and preliminary results.

Background: The unilateral biportal endoscopic (UBE) technique has been widely used in spine surgery. At present, a traditional rigid working channel is available for the UBE system. A metal semicircular canal is located in the working channel.

Ankylosing spondylitis complicated with andersson lesion in the lower cervical spine: A case report.

Background: Andersson lesion (AL) is an uncommon complication in ankylosing spondylitis (AS), which is characterized by nonneoplastic bone destruction and often appears as bone destruction and sclerosis in the vertebral body and/or the area involving the intervertebral disc. According to the literature, Andersson lesion commonly occur in the thoracic and lumbar spine and rarely in the cervical spine.

Case Summary: This case involved a 78-year-old man with a long history of AS who developed AL in the cervical spine (C5/6 and C6/7).
