Background: Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined. Methods: This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months. Conclusion This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

Pediatric differentiated thyroid cancers (DTCs), mostly papillary thyroid cancer (PTC, 80-90%), are diagnosed at more advanced stages with larger tumor sizes and higher rates of locoregional and/or lung metastasis. Despite the higher recurrence rates of pediatric cancers than of adult thyroid cancers, pediatric patients demonstrate a lower mortality rate and more favorable prognosis. Considering the more advanced stage at diagnosis in pediatric patients, preoperative evaluation is crucial to determine the extent of surgery required. Furthermore, if hereditary tumor syndrome is suspected, genetic testing is required. Recommendations for pediatric DTCs focus on the surgical principles, radioiodine therapy according to the postoperative risk level, treatment and follow-up of recurrent or persistent diseases, and treatment of patients with radioiodine-refractory PTCs on the basis of genetic drivers that are unique to pediatric patients.

Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.

Malignant hyperthermia is an extremely rare, potentially lethal disorder that occurs in susceptible patients who are exposed to triggering agents such as volatile anesthetic gases or depolarizing muscle relaxants. The clinical manifestations of malignant hyperthermia include hypermetabolism, hyperthermia, hypercapnia, and sustained skeletal muscle rigidity, which result in cardiac arrest, brain damage, and death. It is associated with a high morbidity and mortality rate if not recognized immediately and treated appropriately. We report a case of suspected malignant hyperthermia in a young male patient undergoing axillary osmidrosis surgery.

Squamous cell carcinoma is the most common cancer occurring in the oral cavity and oncologic wide cancer excision is a major cause of large lip defects. Large lower lip defect reconstruction with good functional and aesthetic results has always presented a challenge for plastic surgeons. There are various lower lip reconstruction methods depending on its size, location, and surgeon’s expertise. This is a case of a large defect spanning more than two-thirds of the lower lip after wide excision due to squamous cell carcinoma. The Karapandzic flap was used to reconstruct the defect with a commissuroplasty carried out in a second operation, which yielded a relatively good functional and aesthetic result. No recurrences or metastases were observed within a one year follow-up period.

Purpose: Eosinophil-derived neurotoxin (EDN) is not the only a marker for eosinophil activation, but also acts as an alarm protein.Very few studies have examined the potential role of eosinophils in the development of bronchopulmonary dysplasia (BPD). This study aims to address the roles of eosinophil and EDN in the early phase of BPD development. Methods: Patients were preterm neonates with respiratory distress syndrome (RDS) born at 36 weeks of gestation or less. Blood and urine samples were collected to measure total eosinophil count in the blood, serum eosinophil cationic protein (ECP), serum EDN, and urinary EDN during the first week of life. Results: Fifty-two preterms were recruited, of whom 43 infants were analyzed. Comparisons were made between the RDS (n = 16) and non-RDS groups (n = 27) and between the BPD (n = 6) and non-BPD groups (n = 26). There were no differences between RDS and non-RDS group in total eosinophil count, serum ECP, serum EDN, or urinary EDN, except when compared by gestational age, birth weight and prenatal dexamethasone use. Urinary EDN was increased significantly in the BPD group compared to the non-BPD group. Conclusion We demonstrated the roles of eosinophil and EDN in the development of BPD and suggest that urinary EDN may be utilized as a noninvasive factor predicting the development of BPD.

Severe facial burns on the peaking portion of the face, such as the nose, and the central facial structure, such as the upper lip, significantly result in ugly facial features. Beyond the functional effects of facial burns, the aesthetic component is critical, and reconstructing these facial postburn scar deformities is always challenging for plastic surgeons. Herein, we present our clinical experience in reconstructing severe postburn scar deformities of the distal nose and philtrum area due to extensive deep burns. The deformed area on the nasal dorsum was reconstructed with ala transdomal turn-over scar flap (ATTSF) and full-thickness skin graft. The philtrum was reconstructed using the fenestrated conchal cartilage composite graft.

Background: In Korea, the birth rate is declining at an alarming pace. This study aimed to investigate the changes and trends in the population count, number of births, and birth rate in Korea, in the past and future. Methods: Data regarding the total number of births, crude birth rate, and total fertility rate were collected from the “Statistics Korea Census” of the national statistical portal, census report, and Statistics Korea’s “2020 Population Trend Survey for 1981–2020, provisional results of birth and death statistics.” We used the Organisation for Economic Co-operation and Development 2019 Family Database for the TFR. To develop a better understanding of the data in this study, we classified it according to the modern history of Korea. Results: The changes and trends in the number of births and fertility rate in Korea, after liberation, were due to the birth control policy that restricted births. In Korea’s low fertility society, which began in the mid-2000s, the fertility rate dropped to below 0.84 in 2020, despite policies to improve the quality of the population. The death toll has reached 300,000, entering an era of population decline. Conclusion As we enter the era of population decline, we are in a direction that will cause various socioeconomic problems, from demographic problems to future population decline.
