Subgaleal hematoma (SGH) is a rare condition in adults, typically resulting from trauma. It has primarily been treated with traditional methods, such as aspiration and needle puncture. However, Conventional treatments, such as simple compression dressings and needle aspiration, have been found inadequate in addressing refractory SGH. To overcome these challenges, we performed endovascular treatment (EVT), involving selective coil embolization of the vessels feeding the hematoma, followed by percutaneous hematoma aspiration and compression dressing. In this case report, a 37-year-old female patient with head trauma developed a recurrent subgaleal hematoma despite conservative treatments. Endovascular treatment was performed, resulting in significant improvement and no recurrence. This case suggests that EVT provides a viable and effective treatment alternative for adult patients with refractory SGH, offering a less invasive approach compared to surgical incision and drainage, with promising long-term outcomes.

Background: s: Alcohol-related liver disease (ALD) is currently a major indication for liver transplantation (LT) in South Korea. Alcoholic recidivism is a primary concern after LT for ALD. However, it is unclear how patients who have received LT for ALD are managed regarding medical and psychological issues. Furthermore, management approaches vary across centers. This study aims to investigate how these management approaches differ among centers. Methods: We conducted a survey of 19 liver transplant centers in South Korea to gather detailed information on the management protocols and related issues of ALD in LT patients. Results: All 19 centers that responded to the survey had been performing LT for patients with ALD for more than 5 years. Nine out of the 19 centers (47%) stated that a minimum abstinence period of 1–6 months from alcohol was required before evaluating LT and enrolling on the transplant waiting list. Only 2 (10%) and 5 (26%) centers had protocols for assessing alcohol consumption while awaiting LT or for treating alcohol consumption after transplantation, respectively. Monitoring abstinence from drinking before and after LT mostly relied on direct interviews, and alcohol biomarkers were not used. Conclusion Our findings emphasize the importance of consistent patient management guidelines for ALD-LTs in South Korea.

Ischemic heart disease remains the primary cause of morbidity and mortality worldwide.Despite significant advancements in pharmacological and revascularization techniques in the late 20th century, heart failure prevalence after myocardial infarction has gradually increased over the last 2 decades. After ischemic injury, pathological remodeling results in cardiomyocytes (CMs) loss and fibrosis, which leads to impaired heart function.Unfortunately, there are no clinical therapies to regenerate CMs to date, and the adult heart’s limited turnover rate of CMs hinders its ability to self-regenerate. In this review, we present novel therapeutic strategies to regenerate injured myocardium, including (1) reconstruction of cardiac niche microenvironment, (2) recruitment of functional CMs by promoting their proliferation or differentiation, and (3) organizing 3-dimensional tissue construct beyond the CMs. Additionally, we highlight recent mechanistic insights that govern these strategies and identify current challenges in translating these approaches to human patients.

Objective: Pre-treatment anxiety (PA) before chemotherapy increases complaints of chemotherapy-related symptoms (CRS). The results on the association have been inconsistent, and the effect of temperament remains unclear. We aimed to determine whether PA is a risk factor for CRS and the effect of differing temperaments on CRS. Methods: This prospective study comprised 176 breast cancer patients awaiting adjuvant chemotherapy post-surgery. We assessed CRS, PA, and temperament using the MD Anderson Symptom Inventory (MDASI), the Hospital Anxiety and Depression Scale, and the short form of the Temperament and Character Inventory-Revised, respectively. The MDASI was re-administered three weeks after the first chemo-cycle. Results: PA showed weak positive correlation with several CRS after the first cycle; no CRS was significantly associated with PA when pre-treatment depressive symptoms and baseline CRS were adjusted in multiple regression analysis. Moderation model analysis indicated that the PA effect on several CRS, including pain, insomnia, anorexia, dry mouth, and vomiting, was moderated by harm avoidance (HA) but not by other temperament dimensions. In particular, PA was positively associated with CRS in patients with low HA. Conclusion The results in patients with low HA indicate that more attention to PA in patients with confident and optimistic temperaments is necessary.

Background: The performance of the pulse oximeter was evaluated based on the ISO 80601-2-61:2011 (E) guidelines. This study aimed to determine whether the various finger probes of the MP570T pulse oximeter (MEK-ICS Co., Ltd., Korea) would provide clinically reliable peripheral oxygen saturation (SpO2) readings over a range of 70100% arterial oxygen saturation (SaO2) during non-motion conditions. Methods: Each volunteer (n = 12) was connected to a breathing circuit for the administration of a hypoxic gas mixture. For frequent blood sampling, an arterial cannula was placed in a radial artery. The following seven pulse oximeter probes were simultaneously attached to each volunteer’s fingers: (1) WA-100 reusable finger probe (MEDNIS Co., Ltd., Korea), (2) MDNA disposable finger probe (MEDNIS Co., Ltd.), (3) IS-1011 disposable finger probe (Insung Medical Co., Ltd., Korea), (4) CJ340NA disposable finger probe (CHUN JI IN Medical Co., Ltd., Korea), (5) NellcorTM OxiMax DS-100A reusable finger probe (Medtronic, USA), (6) NellcorTM OxiMax MAX-N disposable finger probe (Medtronic), and (7) OXI-PRO DA disposable finger probe (Bio-Protech Inc., Korea). Results: A total of 275 SpO2-SaO2 pairs were included in the analysis. The accuracy of the root mean square (Arms) of each probe was 2.83%, 3.98%, 3.75%, 6.84%, 3.43%, 5.17%, and 3.84%, respectively. Conclusions The MP570T pulse oximeter with WA-100 reusable, MDNA disposable, IS-1011 disposable, NellcorTM OxiMax DS-100A reusable, and OXI-PRO DA disposable finger probes meets an acceptable standard of SpO2 accuracy under non-motion conditions.

Nipple reconstruction methods include various techniques, such as the local flap technique, free nipple grafting, and filler injection. The local flap technique can provide less donor site morbidity than a free nipple graft, but leaves an additional scar near the nipple. We present a novel method for reconstruction of the nipple using a flap located on one side of the nipple. The flap has a teardrop shape consisting of a circle and two wings folded to one side. The two wings form a pillar and cap, and the de-epithelialized tip of one wing fills the internal dead space of the new nipple. We applied this nipple reconstruction technique in the case of a 61-year-old patient who had a vertical scar due to inverted-T reduction mammoplasty. The patient had lost her nipple in previous breastconserving surgery. The immediate postoperative nipple projection was 10 mm. At the 7-month follow-up visit, the nipple projection was 7.5 mm. The teardrop flap is an innovative technique that leaves no additional scar by using the scar already present on one side of the nipple.

Background: The international organization for standardization (ISO) 80601-2-61 dictates that the accuracy ofa pulse oximeter should be assessed by a controlled desaturation study. We aimed to characterize the relationshipbetween the fraction of inspired oxygen (FiO2) and peripheral oxygen saturation (SpO2) using a turnover modelby retrospectively analyzing the data obtained from previous controlled desaturation studies. Materials and Methods: Each volunteer was placed in a semi-Fowler’s position and connected to a breathingcircuit to administer the hypoxic gas mixture containing medical air, oxygen, nitrogen, and carbon dioxide.Volunteers were exposed to various levels of induced hypoxia over 70-100% arterial oxygen saturation (SaO2).The study period consisted of two rounds of hypoxia and the volunteers were maintained in room air betweeneach round. FiO2 and SpO2 were recorded continuously during the study period. A population pharmacodynamicanalysis was performed with the NONMEM VII level 4 (ICON Development Solutions, Ellicott City, MD,USA). Results: In total, 2899 SpO2 data points obtained from 20 volunteers were used to determine the pharmacodynamiccharacteristics. The pharmacodynamic parameters were as follows: kout = 0.942 1/min, Imax = 0.802, IC50 =85.3%, γ = 27.3. Conclusion The changes in SpO2 due to decreases in FiO2 well explained by the turnover model with inhibitoryfunction as a sigmoidal model.

This clinical practice position statement, a product of the Fatty Liver Research Group of the Korean Diabetes Association, proposes recommendations for the diagnosis, progression and/or severity assessment, management, and follow-up of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus (T2DM). Patients with both T2DM and NAFLD have an increased risk of non-alcoholic steatohepatitis (NASH) and fibrosis and a higher risk of cardiovascular diseases and diabetic complications compared to those without NAFLD. With regards to the evaluation of patients with T2DM and NAFLD, ultrasonography-based stepwise approaches using noninvasive biomarker models such as fibrosis-4 or the NAFLD fibrosis score as well as imaging studies such as vibration-controlled transient elastography with controlled attenuation parameter or magnetic resonance imaging-proton density fat fraction are recommended. After the diagnosis of NAFLD, the stage of fibrosis needs to be assessed appropriately. For management, weight reduction achieved by lifestyle modification has proven beneficial and is recommended in combination with antidiabetic agent(s). Evidence that some antidiabetic agents improve NAFLD/NASH with fibrosis in patients with T2DM is emerging. However, there are currently no definite pharmacologic treatments for NAFLD in patients with T2DM. For specific cases, bariatric surgery may be an option if indicated.

Telecanthus is a common symptom accompanied by Waardenburg syndrome, a rare genetic disorder. The optimal surgery for telecanthus correction is still debated. A 28-year-old patient with Waardenburg syndrome underwent transnasal wiring canthopexy using a Y-V epicanthoplasty for telecanthus correction. A Mini-Monoka stent was used to prevent damage to the lacrimal apparatus. The intercanthal distance decreased from 50 mm to 43.2 mm. The easily designed Y-V epicanthoplasty incision provides sufficient operative field for oblique transnasal wiring, which is effective in properly positioning the medial canthal tendon. It has minimal scarring resulting in satisfactory cosmetic outcomes.

PURPOSE: Pain management in burn treatment is important in improving wound healing and quality of life. Ibuprofen is a proven pain relieving agent in patients with partial thickness burn by intraveous injection. The purpose of this study is to evaluate the efficacy of Biatain Ibu® (polyurethane foam containing ibuprofen) in pain control for outpatients with partial thickness burns. METHODS: A prospective randomized clinical trial was performed in outpatients with partial thickness burn from August 1, 2017 to July 31, 2018. Acute pain, chronic pain, complications, days for re-epithelialization and patient's satisfaction were compared between Biatain Ibu® and Biatain® groups. RESULTS: A total of 20 patients (Biatain Ibu®, n=10; Biatain®, n=10) were assessed in the trial. On Burn days 3, 5, 7, 11, 13, and 15, the acute pain levels were significantly lower in the Biatain Ibu® group than in the Biatain® group. Complications, chronic pain levels and days for re-epithelialization were not significantly different between the two groups. Patient's satisfaction was not statistically significant but was higher in the Biatain Ibu® group. CONCLUSION: Biatain Ibu® is effective in relieving pain in outpatients with partial thickness burn without decreasing patient satisfaction, wound healing ability or developing any complications.
