Intradural lumbar disc herniation (ILDH) is a very rare condition, with cerebrospinal fluid (CSF) leakage as a postoperative complication. The central canal of the conus medullaris was reported to communicate with the subarachnoid space through a caudal aperture; however, this aperture has never been observed in vivo. Herein, we report a case of L1/2 ILDH with postoperative spinal adhesive arachnoiditis and syringomyelia in which the communication considered to be a caudal aperture was detected.

Retinal ganglion cells (RGCs) generally fail to regenerate axons, resulting in irreversible vision loss after optic nerve injury. While many studies have shown that modulating specific genes can enhance RGCs survival and promote optic nerve regeneration, inducing long-distance axon regeneration through single-gene manipulation remains challenging. Nevertheless, combined multi-gene therapies have proven effective in significantly enhancing axonal regeneration.

Trans-arterial omental flap protection for infected femoral artery aneurysm in a patient with Parkes-Weber syndrome.

J Vasc Surg Cases Innov Tech

February 2025

Division of Vascular Surgery, Department of Surgery, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan.

We report a case of a 75-year-old man diagnosed with Parkes-Weber syndrome with an infected common femoral artery aneurysm secondary to chronic venous ulcers and groin infection. Given the symptomatic and rapid enlargement of the aneurysm, emergency aneurysmectomy and crossover femoro-femoral bypass were performed with an omental flap routed intraluminally through the aneurysm of the ipsilateral external iliac artery. The transarterial route enabled the short-cutting of the omental flap and the potential prevention of infection in the adjacent external iliac artery.

Background: Anorexia nervosa has the highest mortality rate of any psychiatric disorder, and purging behaviors can cause a fatal electrolyte and acid-base imbalance. Routine laboratory testing during inpatient care is essential because these patients often provide inaccurate information about their diet and purging behaviors. However, blood gas analysis for an acid-base evaluation is rarely performed in the psychiatric setting because psychiatrists are not accustomed to evaluating the results.

Functional Improvements by Controlled Suture Tension in Arthroscopic Rotator Cuff Repair.

JB JS Open Access

January 2025

Department of Orthopaedic Surgery, University Hospital, Shiga University of Medical Science, Shiga, Japan.

Background: Although a certain degree of tension in bridging sutures is required for proper tendon healing following suture-bridge rotator cuff repair, excessive suture tension may be detrimental to tendon healing. This study aimed to investigate the effects of bridging suture tension on clinical outcomes and tendon healing. We hypothesized that fixed, low tension of the bridging sutures would improve the tendon healing rate and clinical outcomes compared with maximum manual tensioning.

Background: Peritumoral lidocaine infiltration prior to excision is associated with better survival in breast cancer (BC), which led us to hypothesize that innervation to the tumor affects its biology and patient survival. Activity-regulated cytoskeleton-associated protein (ARC) gene expression is known to be regulated by neuronal activity. Therefore, we studied the clinical relevance of ARC gene expression as a surrogate of neuronal activity in BC.
