Purpose:
Ultrasound-guided nerve hydrodissection has emerged as a potential non-surgical treatment for carpal tunnel syndrome (CTS). The objective of this research was to offer suggestions for optimizing injectables utilized in hydrodissection for the treatment of CTS through a systematic review and network meta-analysis.
Materials and Methods:
PubMed, MEDLINE, EMBASE, Cochrane, Scopus, and Web of Science were searched through April 25, 2024. Effect sizes were quantified using standard mean differences within a random-effects model. Effectiveness ranking for each treatment was expressed as the surface under the cumulative ranking curve (SUCRA).
Results:
Nine studies with 458 patients with CTS were included. According to SUCRA, 5% dextrose (DW) was the most effective option for the Boston Carpal Tunnel Questionnaire (BCTQ) function at 99.9, 89.8, and 88.8 at 4, 12, and 24 weeks, respectively; for BCTQ symptoms, 5% DW was the most effective option at 99.9 at 4 weeks and platelet-rich plasma at 95.7 and 93.9 at 12 and 24 weeks, respectively. In terms of both BCTQ symptoms and BCTQ function, the 5 cc injection was the most effective, with SUCRA values of 99.5 for both categories. However, the effectiveness of the electrodiagnostic assessment and ultrasound variables was dependent on the type and dose of medication.
Conclusion
Administration of 5% DW showed better results in terms of initial symptom relief and long-term functional recovery compared to other agents, while platelet-rich plasma showed greater long-term symptom improvement; an injection dose of 5 cc showed the greatest benefit. However, additional research is required to establish precise protocols based on disease severity.

Purpose:
Pediatric papillary thyroid cancer (PTC) is recommended to perform aggressive surgery to reduce the risk of recurrence.This study was designed to evaluate the concurrent association between multifocality, bilaterality, and the risk of recurrence in pediatric PTC.
Materials and Methods:
This retrospective cohort study included pediatric patients (age <19 years) who underwent total thyroidectomy for PTC between 1996 and 2014 in a single tertiary center. Clinicopathological parameters were analyzed to evaluate the prevalence of multifocality, bilaterality, recurrence, and their association.
Results:
We analyzed 58 pediatric patients with PTC. There was no factor related to the presence of multifocality or bilaterality in multivariate analysis. Also, in univariate analysis, multifocality and bilaterality were not independent risk factors of each other’s presentation (p=0.061 and p=0.061, respectively). Recurrence was observed in 19 (32.8%) patients. In multivariate analysis of recurrence, clear cell subtype, multifocality, and gross extrathyroidal extension (ETE) were independent risk factors (p=0.027, p=0.035, and p=0.038, respectively). Most recurrences (68.4%) happened during the first 4 years of follow-up after the initial thyroidectomy.
Conclusion
Multifocality and bilaterality were not independent risk factors of each other’s presentation; however, multifocality was the risk factor for recurrence in pediatric PTC. For pediatric PTC, close monitoring for recurrence within the initial 4 years is recommended, particularly in patients with clear cell subtype, multifocality, and gross ETE.

Obstructive sleep apnea (OSA), characterized by nocturnal airway obstruction, hypoxia, and arousal, is a significant risk factor for cardiovascular diseases, including arrhythmia. This case report describes the association between OSA and nocturnal sinus tachycardia in a 58-year-old woman who presented with sleep maintenance difficulties and recurrent nocturnal tachycardia. Polysomnography confirmed a direct correlation among the apnea/hypopnea episodes, tachycardia, and sleep maintenance difficulties. Continuous positive airway pressure therapy effectively resolved tachycardia and sleep maintenance difficulties, reducing the number of medications required to alleviate the symptoms. This report highlights the importance of considering OSA as a possible cause of unexplained nocturnal tachycardia.

Ketone bodies produced by sodium-glucose cotransporter 2 (SGLT2) inhibitors can be advantageous, providing an efficient and stable energy source for the brain and muscles. However, in patients with diabetes, ketogenesis induced by SGLT2 inhibitors may be harmful, potentially resulting in severe diabetic ketoacidosis (DKA). During fasting, ketone body production serves as an alternative and efficient energy source for the brain by utilizing stored fat, promoting mental clarity, and reducing dependence on glucose. The concurrent use of SGLT2 inhibitors during perioperative fasting may further elevate the risk of euglycemic DKA. We describe a case of DKA that occurred during perioperative fasting in a patient receiving empagliflozin, an SGLT2 inhibitor. This case underscores the importance of recognizing the potential risk of DKA in patients with diabetes using SGLT2 inhibitors during perioperative fasting.

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.

Purpose:
This study aimed to evaluate current morbidity rates following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with colorectal cancer and peritoneal metastasis.
Methods:
A total of 42 patients who underwent CRS and HIPEC for colorectal cancer with peritoneal metastasis at a single tertiary referral center between January 2022 and December 2022 were included. Perioperative outcomes and postoperative complications were prospectively assessed.
Results:
The mean peritoneal cancer index (PCI) was 16.0. The distribution of PCI scores was as follows: <10, 33.3%; 10– 19, 26.2%; and ≥ 20, 40.5%. Completeness of the cytoreduction (CCR) scores were as follows: 57.1% of patients achieved CCR-0, 16.7% achieved CCR-1, 7.1% achieved CCR-2, and 19.0% achieved CCR-3. The mean operation time was 9.1 hours, and the median hospital stay was 17.0 days. Postoperative complications occurred within 30 days in 47.6% of cases and between 30 and 60 days in 11.9% of cases. Reoperation within 30 days was required in 5 cases, and 1 patient died within 30 days. The most common complications were pleural effusion (5 patients), anastomosis site leakage (3 patients), and pneumonia (3 patients). Patients with higher PCI scores were more likely to experience complications (P = 0.038).
Conclusion
Although CRS and HIPEC are still associated with high morbidity and mortality compared to other colorectal surgeries, outcomes have improved with increased experience. These results suggest that the procedure is becoming a more acceptable treatment option over time.

The use of miniscrew-assisted rapid palatal expansion (MARPE) has yielded successful outcomes in late adolescence and early adulthood, particularly in correcting transverse maxillary discrepancies and enhancing airway expansion. This report presents three cases of children at different dentition stages treated with MARPE. In one patient with severe crowding, MARPE enabled dental alignment without the need for premolar extractions. Additionally, MARPE combined with facemask therapy improved the patient’s facial profile, resulting in high patient and guardian satisfaction. These cases highlight MARPE’s potential as an effective treatment for maxillary discrepancies and severe arch length discrepancies in children.

Journal of the Korean Society of Emergency Medicine 2025;36(2):72-82
Objective:
The Daegu region experienced the first wave of the pandemic at the beginning of the coronavirus disease 2019 (COVID-19) outbreak in Korea. Other non-COVID-19-related treatments during a community outbreak, such as cardiovascular diseases, were expected to impact emergency departments. In acute myocardial infarctions, time is an important factor affecting the patient outcome. This study examined how community COVID-19 outbreak affected STsegment elevated myocardial infarction (STEMI) care in emergency departments.
Methods:
A retrospective analysis was performed on patients visiting five emergency departments in the Daegu area who were diagnosed with STEMI from February 18 to April 17 each year from 2018 to 2020. The demographic characteristics, prehospital variables, in-hospital time variables, and treatment results were collected. The cases were divided into the pre-COVID period and the COVID period for comparison.
Results:
The study included 254 patients (194 pre-COVID, 60 during COVID). The symptom-to-door time did not differ. Although the door-to-first doctor time was shortened (4 min vs. 2 min, P=0.01), the rate of coronary angiogram along with the door-to-angiogram time and the door-to-balloon time did not change. The length of stay in the emergency department was delayed during COVID-19 (median, 136 min vs. 404 min; P<0.01). The in-hospital length of stay and mortality were similar in both groups.
Conclusion
The time to treat STEMI was not delayed significantly during the first wave of the COVID-19 outbreak in the Daegu area compared with the pre-pandemic period. Mortality did not change. The length of stay was elongated significantly in the emergency department but not in the hospital.
