Purpose: To describe the use of a ruler to increase the accuracy and customization of Lester Jones tube placement.
Materials And Methods: This was a review of 92 patients who underwent minimally invasive conjunctivodacryocystorhinostomy using this instrument.
Results: The success rate was 100%, with an average operating time of 15 minutes. In nine patients, late migration of the Jones tube into the nasal cavity required a secondary intervention, with successful Jones tube repositioning. In five cases, obstruction of the tube opening was caused by conjunctival overgrowth.
Conclusion: The millimetric ruler engraved in the sleeve of the trocar allows measuring and placing a personalized tube for each patient.

Parkinson's disease (PD) is a common neurodegenerative condition that can lead to problems swallowing. Individuals living with PD may be unable to take medications orally for various reasons including acute or chronic dysphagia, non-PD related causes and being placed nil-by-mouth for elective reasons. This article outlines a five-step approach to managing an individual living with PD who is unable to take oral medication acutely.

Purpose: To evaluate the efficacy and safety of the Paul Glaucoma Implant (PGI) surgery in patients with secondary glaucomas.
Patients And Methods: Retrospective chart review of adult patients with medically recalcitrant secondary glaucoma who underwent PGI implantation at a single tertiary center between August 2022 and June 2023. The primary outcome measure was surgical success.
Multiple myeloma-associated non-crystalline proximal tubulopathy and crystalline cast nephropathy: Biochemical and structural features of disease-causing monoclonal kappa light chains.

Various tubular diseases in patients with multiple myeloma (MM) are caused by monoclonal immunoglobulin light chains (LCs). However, the physicochemical characteristics of the disease-causing LCs contributing to the onset of MM-associated tubular diseases remain unclear. We herein report a rare case of MM-associated combined tubulopathies: non-crystalline light chain proximal tubulopathy (LCPT) and crystalline light chain cast nephropathy (LCCN).

Background And Objectives: Cold-stored whole blood (CS-WB) in paediatric cardiac surgery is making a resurgence, given its identified benefits compared to conventional blood component therapy (CT).
Study Design And Methods: A single-centre retrospective study was conducted from January 2018 to October 2018 by including children <18 years of age undergoing cardiac surgery requiring cardiopulmonary bypass. ABO-compatible CS-WB from non-directed random donors was leukoreduced with platelet-sparing filters and compared with CT.
The incorporation of MALDI mass spectrometry imaging in studies to identify markers of toxicity following opioid exposures in mouse fetuses.

Introduction: In 2015, the FDA released a Drug Safety Communication regarding a possible link between opioid exposure during early pregnancy and an increased risk of fetal neural tube defects (NTDs). At the time, the indications for opioid use during pregnancy were not changed due to incomplete maternal toxicity data and limitations in human and animal studies. To assess these knowledge gaps, largescale animal studies are ongoing; however, state-of-the-art technologies have emerged as promising tools to assess otherwise non-standard endpoints.
