Background and Objectives: Patients with voice disorders often face difficulties in managing their vocal health in daily life, highlighting the need for voice management and hygiene education without temporal or spatial limitations. This study aimed to evaluate the usability of a smartphone-based voice hygiene application developed for patients with voice disorders.Materials and Method Thirty patients diagnosed with voice disorders who underwent voice therapy participated in the study. After using the voice hygiene application for 4 weeks, participants completed a usability questionnaire composed of ten items across five key categories: aesthetics, functionality, engagement, usability, and reliability (two items per category). Results: The overall usability score of the voice hygiene application was 3.94 out of 5. The highest ratings were observed in aesthetic design and convenience. Engagement was positively influenced by the app’s reminder feature, and satisfaction regarding information reliability and system functionality was also generally high. Conclusion The voice hygiene application was found to be a useful tool for supporting self-management and maintaining vocal hygiene among patients with voice disorders through unrestricted accessibility. This study suggests that such applications can promote consistent voice hygiene practices and contribute to the improvement of vocal health.

Intracranial hypotension typically presents with orthostatic headache caused by cerebrospinal fluid (CSF) hypovolemia, most commonly resulting from spontaneous or iatrogenic CSF leaks. Traumatic rupture of an occult congenital sacral meningocele following a minor injury is exceptionally rare and may be diagnostically challenging. We report the case of a 40-year-old woman in Korea who developed sudden severe orthostatic headache immediately after a minor coccygeal contusion. Magnetic resonance myelography demonstrated a 5.8-cm dural ectasia/meningocele at the S3 level with a focal CSF fistula extending into the presacral space, accompanied by a tethered cord and an intradural lipoma. Given the anticipated risks associated with definitive surgical repair, a targeted trans-sacrococcygeal epidural blood patch was administered, resulting in substantial symptomatic improvement. This case highlights that while most post-traumatic CSF leaks occur at the cervical or thoracic level, occult spinal dysraphism should be considered a rare predisposing factor in post-traumatic orthostatic headache, particularly when trauma involves the sacrococcygeal region or when standard imaging findings are unrevealing. This finding also suggests that targeted caudal epidural blood patches may serve as a reasonable and less invasive treatment option when surgical intervention carries a high risk.

Purpose: This study aimed to develop a comprehensive practical guide for enteral nutrition (EN) designed to enhance patient safety and reduce complications in Korea. Under the leadership of the Korean Society for Parenteral and Enteral Nutrition (KSPEN), the initiative sought to standardize EN procedures, improve decision-making, and promote effective multidisciplinary communication. Methods: The KSPEN EN committee identified key questions related to EN practices and organized them into seven sections such as prescribing, delivery route selection, formula preparation, administration, and quality management. Twenty-one experts, selected based on their expertise, conducted a thorough literature review to formulate evidence-based recommendations. Drafts underwent peer review both within and across disciplines, with final revisions completed by the KSPEN Guideline Committee. The guide, which will be published in three installments, addresses critical elements of EN therapy and safety protocols. Results: The practical guide recommends that EN orders include detailed elements and advocates the use of electronic medical records for communication. Standardized prescription forms and supplementary safety measures are outlined. Review frequency is adjusted according to patient condition—daily for critically ill or unstable patients and as dictated by institutional protocols for stable patients. Evidence indicates that adherence to these protocols reduces mortality, complications, and prescription errors. Conclusion The KSPEN practical guide offers a robust framework for the safe delivery of EN tailored to Korea’s healthcare context. It emphasizes standardized protocols and interdisciplinary collaboration to improve nutritional outcomes, patient safety, and operational efficiency. Rigorous implementation and monitoring of adherence are critical for its success.

The Korean Enhanced Recovery After Surgery (ERAS) Committee within the Korean Society of Surgical Metabolism and Nutrition was established to develop ERAS guidelines tailored to the Korean context. This guideline focuses on creating the most current evidence-based practice guidelines for ERAS purposes, based on systematic reviews. All key questions targeted randomized controlled trials exclusively, and if fewer than 2 were available, studies employing propensity score matching were also included. Recommendations for each key question were marked with strength of recommendation and level of evidence following internal and external review processes by the committee.

Background: The accuracy of Logical Observation Identifiers Names and Codes (LOINC) mappings is reportedly low, and the LOINC codes used for research purposes in Korea have not been validated for accuracy or usability. Our study aimed to evaluate the discrepancies and similarities in interoperability using existing LOINC mappings in actual patient care settings. Methods: We collected data on local test codes and their corresponding LOINC mappings from seven university hospitals. Our analysis focused on laboratory tests that are frequently requested, excluding clinical microbiology and molecular tests. Codes from nationwide proficiency tests served as intermediary benchmarks for comparison. A research team, comprising clinical pathologists and terminology experts, utilized the LOINC manual to reach a consensus on determining the most suitable LOINC codes. Results: A total of 235 LOINC codes were designated as optimal codes for 162 frequent tests.Among these, 51 test items, including 34 urine tests, required multiple optimal LOINC codes, primarily due to unnoted properties such as whether the test was quantitative or qualitative, or differences in measurement units. We analyzed 962 LOINC codes linked to 162 tests across seven institutions, discovering that 792 (82.3%) of these codes were consistent. Inconsistencies were most common in the analyte component (38 inconsistencies, 33.3%), followed by the method (33 inconsistencies, 28.9%), and properties (13 inconsistencies, 11.4%). Conclusion This study reveals a significant inconsistency rate of over 15% in LOINC mappings utilized for research purposes in university hospitals, underlining the necessity for expert verification to enhance interoperability in real patient care.

The femoral artery is the preferred access route for neurointerventions. The transfemoral approach (TFA) offers advantages such as a large diameter and easy access. However, it also entails disadvantages such as patient discomfort and high risk of complications. Following the initial report of coronary angiography using the transradial approach (TRA) in 1989, cardiologists discovered the advantages of TRA over the TFA and gradually replaced it with the TRA. In 1997, Matsumoto et al. used the TRA for cerebral angiography and neurointervention. Thereafter, the adoption of TRA for neurointervention gradually increased and good outcomes were reported. However, despite these developments, the adoption rate of TRA is relatively low. We reviewed the relevant studies to increase the accessibility of TRA for neurointerventionists.
