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.

Purpose:
Firefighting duties range from field roles such as suppression, rescue, and emergency medical services (EMS) to various administrative tasks. Despite these differences, they face uniform fitness standards in Korea. This study seeks to define distinct fitness needs for each duty and provide data for customized standards.
Methods:
One hundred seventy-six Korean male firefighters participated, categorized into suppression (n=76), rescue (n=22), administrative (n=27), and EMS (n=51) roles. All underwent maximal oxygen consumption (VO2 max) tests for aerobic capacity, with body composition measured using bioelectrical impedance and height recorded with a stadiometer.
Results:
The VO2 max (mL/kg/min) among Korean male firefighters varied across different job duties: suppression (39.96±5.84), rescue (44.84±4.85), administration (40.27±7.01), and EMS (40.51±6.75). Rescue had the highest VO2 max, which was significantly higher (p=0.013). The body mass index (BMI, kg/m2 ) values were as follows: suppression (25.07±2.55), rescue (24.95±1.71), EMS (24.33±3.21), and administration (25.10±2.48). There was no statistically significant difference in BMI values (p=0.464).
Conclusion
This study evaluated the VO2 max and BMI of South Korean male firefighters according to their job duties. It found that 54.5% did not meet the recommended VO2 max standard of 42 mL/kg/min for their activities, and 77.5% had a BMI indicating overweight or higher. However, it is important to note that not every firefighting duty requires high fitness levels. The key is ensuring firefighters possess the fitness necessary for their specific roles to maintain safety and efficiency. The study aims to provide data for creating fitness management guidelines tailored to the diverse duties of firefighters.

Inflammation is a series of host defense processes in response to microbial infection and tissue injury. Inflammatory processes frequently cause extracellular acidification in the inflamed region through increased glycolysis and lactate secretion. Therefore, the immune cells infiltrating the inflamed region encounter an acidic microenvironment. Extracellular acidosis can modulate the innate immune response of macrophages; however, its role for inflammasome signaling still remains elusive. In the present study, we demonstrated that macrophages exposed to an acidic microenvironment exhibited enhanced caspase-1 processing and IL-1β secretion compared with those under physiological pH. Moreover, exposure to an acidic pH increased the ability of macrophages to assemble the NLR family pyrin domain containing 3 (NLRP3) inflammasome in response to an NLRP3 agonist.This acidosis-mediated augmentation of NLRP3 inflammasome activation occurred in bone marrow-derived macrophages but not in bone marrow-derived neutrophils. Notably, exposure to an acidic environment caused a reduction in the intracellular pH of macrophages but not neutrophils. Concordantly, macrophages, but not neutrophils, exhibited NLRP3 agonist-mediated translocation of chloride intracellular channel protein 1 (CLIC1) into their plasma membranes under an acidic microenvironment. Collectively, our results demonstrate that extracellular acidosis during inflammation can increase the sensitivity of NLRP3 inflammasome formation and activation in a CLIC1-dependent manner. Thus, CLIC1 may be a potential therapeutic target for NLRP3 inflammasome-mediated pathological conditions.

PURPOSE: To evaluate the postoperative outcome of the multiple slit on plaque plication technique for the treatment of Peyronie's disease. MATERIALS AND METHODS: We retrospectively evaluated 22 patients who underwent plaque incision with penile plication for the surgical treatment of Peyronie's disease, who had failed medical treatment between 2009 and 2014. Patients were grouped by preoperative degree of penile curvature into Group I: mild (n=5, 22.7%), Group II: moderate (n=11, 50.0%), and Group III: severe (n=6, 27.3%). After a thorough review of the medical records, we evaluated (a) the correction of the curvature; (b) sexual function; and (c) any penile shortening or other complications. RESULTS: The mean postoperative follow-up period was 39 months. Complete correction of the curvature was attained in 21 patients (95.5%). As an inevitable complication, minimal penile shortening (<1.5 cm) was reported by 14 patients (82.4%) but did not adversely affect sexual intercourse (0%), and all patients found the extent of penile shortening to be acceptable. Nineteen patients had good erectile function (International Index of Erectile Function >21). The most frequent complication was subcutaneous penile edema in three patients (13.6%), which was resolved within about 3 months following surgery. CONCLUSIONS: As a modified technique, multiple slit on plaque with plication is a simple, minimally-invasive and effective technique for correcting penile curvature regardless of curvature severity. The degree of penile curvature does not significantly predict the amount of penile length loss.

PURPOSE: This study was designed to evaluate the efficacy of medical treatment of Peyronie's disease. MATERIALS AND METHODS: A total of 109 patients with Peyronie's disease who had been treated from January 2011 to December 2014 were retrospectively reviewed in this study. Forty-four patients (Group 1) were treated with 12 mg of potassium para-aminobenzoate daily. Sixty-five patients (Group 2) were treated with combination therapy: tamoxifen (20 mg) and acetyl-L-carnitine (300 mg) twice daily in addition to a phosphodiesterase type 5 inhibitor. Ability to perform sexual intercourse, pain during erection, size of plaque, and penile curvature angle were assessed. RESULTS: In Group 1, 30 of 44 patients (68.2%) discontinued treatment within 12 weeks, while 5 patients (7.7%) in Group 2 discontinued treatment. Pain during erection and plaque size were improved in both groups but showed no statistical difference due to the high dropout rate in Group 1. In both groups, penile curvature was improved, but demonstrated no statistical difference between the treatment groups. However, combination therapy demonstrated a better response rate in patients whose penile curvature angle was less than 30° (44.4% vs. 79.1%, p=0.048). The rate of successful sexual intercourse was significantly higher in Group 2 (42.8% vs. 78.3%, p=0.034). The number of patients who underwent surgical correction despite medical treatment was significantly higher in Group 1 (35.7% vs. 13.3%, p=0.048). CONCLUSIONS: Early medical combination therapy in Peyronie's disease may present better results in patients whose curvature angle is less than 30°.

In the present study, we investigated the effects of treadmill exercise on lipid peroxidation and Cu,Zn-superoxide dismutase (SOD1) levels in the hippocampus of Zucker diabetic fatty (ZDF) rats and lean control rats (ZLC) during the onset of diabetes. At 7 weeks of age, ZLC and ZDF rats were either placed on a stationary treadmill or made to run for 1 h/day for 5 consecutive days at 16~22 m/min for 5 weeks. At 12 weeks of age, the ZDF rats had significantly higher blood glucose levels and body weight than the ZLC rats. In addition, malondialdehyde (MDA) levels in the hippocampus of the ZDF rats were significantly higher than those of the ZLC rats whereas SOD1 levels in the hippocampus of the ZDF rats were moderately decreased. Notably, treadmill exercise prevented the increase of blood glucose levels in ZDF rats. In addition, treadmill exercise significantly ameliorated changes in MDA and SOD1 levels in the hippocampus although SOD activity was not altered. These findings suggest that diabetes increases lipid peroxidation and decreases SOD1 levels, and treadmill exercise can mitigate diabetes-induced oxidative damage in the hippocampus.

PURPOSE: This study was performed to investigate the discomfort reported by patients taking phosphodiesterase type 5 inhibitors (PDE5Is) in clinical practice. MATERIALS AND METHODS: From September 2011 to March 2012, we surveyed patients who were prescribed PDE5Is for erectile dysfunction (ED). The questionnaire elicited information concerning: patient characteristics, medication counseling received and inconveniences experienced in hospitals and at pharmacies, effects of PDE5Is, and the separation of the prescribing and the dispensing of PDE5Is. RESULTS: A total of 237 patients completed the questionnaire (mean age: 58.81+/-9.14 years). Among the 62 patients (26.0%) who reported having encountered some inconveniences in hospitals, the most frequently expressed concerns 'assistant staff,' including nurses (38.7%), 'testing procedures' (27.4%), and 'the issuing of prescriptions' (22.6%). Of the 137 patients (57.8%) who noted inconveniences in obtaining medications from pharmacies, 60.6% cited 'self-consciousness' as the most common reason, followed by 'insufficient medication counseling' (22.6%), and 'absence of consultation' (11.6%). In contrast, 82% of the patients were satisfied with the medication counseling that they had received in hospitals, covering drug usage, side effects, and precautions regarding PDE5Is; this proportion was only 30% for pharmacies. Further, most patients (89%) indicated that they preferred to obtain their prescriptions and medications for ED from the hospital at the same time. CONCLUSIONS: Treatment of ED is a highly private matter. According to the survey, ED patients more often felt that obtaining medication from pharmacies was inconvenient. The sociocultural aspects of ED necessitate that exceptions to separating the prescribing and the dispensing of medication be considered.

PURPOSE: To identify prognostic factors for the outcomes of empirical antifungal therapy, we performed a multicenter, prospective, observational study in immunocompromised patients with hematological malignancies. MATERIALS AND METHODS: Three hundred seventy-six patients (median age of 48) who had neutropenic fever and who received intravenous (IV) itraconazole as an empirical antifungal therapy for 3 or more days were analyzed. The patients with possible or probable categories of invasive fungal disease (IFD) were enrolled. RESULTS: The overall success rate was 51.3% (196/376). Age >50 years, underlying lung disease (co-morbidity), poor performance status [Eastern Cooperative Oncology Group (ECOG) > or =2], radiologic evidence of IFD, longer duration of baseline neutropenic fever (> or =4 days), no antifungal prophylaxis or prophylactic use of antifungal agents other than itraconazole, and high tumor burden were associated with decreased success rate in univariate analysis. In multivariate analysis, age >50 years (p=0.009) and poor ECOG performance status (p=0.005) were significantly associated with poor outcomes of empirical antifungal therapy. Twenty-two patients (5.9%) discontinued itraconazole therapy due to toxicity. CONCLUSION: We concluded that empirical antifungal therapy with IV itraconazole in immunocompromised patients is effective and safe. Additionally, age over 50 years and poor performance status were poor prognostic factors for the outcomes of empirical antifungal therapy with IV itraconazole.

Cleft lip and palate is congenital deformity in oral and maxillofacial area. Normal soft palate has velopharyngeal closure action by connecting oral cavity and nasal cavity at rest and moving upward at swallowing and specific pronunciation. Cleft palate patients with velopharyngeal insufficiency have difficulty in mastication, swallowing and pronunciation because velopharyngeal closure is incomplete. At this time, a prosthetic device used to cover palate defects is called a palatal obturator. A palatal obturator separates oral cavity and nasal cavity and recovers pronunciation, mastication, swallowing and esthetic function. The purpose of this case study is to report the results because it reaches a satisfactory result in functional and esthetic aspects through functional impression procedures using modeling compound and tissue conditioner for restoration of a cleft palate patient with velopharyngeal insufficiency.
