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.

PURPOSE: The aim of the present study was to evaluate the efficacy and safety of the electromagnetic-type low-intensity extracorporeal shock wave therapy (Li-ESWT) in patients with erectile dysfunction (ED).MATERIALS AND METHODS: The randomized, sham-controlled, double-blind prospective study was performed at two referral hospitals. Participants were randomized in a 1:1 ratio to receive sham or Li-ESWT for 6 weeks. ED was evaluated at screening and at 4 and 7 weeks after treatment. Participants were asked to complete the international index of erectile function-erectile function (IIEF-EF) domain questionnaire, erection hardness scale (EHS), and sexual encounter profile questionnaire (SEPQ 2 and 3). The development of complications was investigated.RESULTS: Eighty-one of 96 patients completed the study. The median change in the IIEF-EF score in the Li-ESWT and sham groups was 5.1 and −2.2 (p<0.001), respectively, at the 7-week follow-up; 47.4% (18/38) patients had EHS <3, of which 77.8% (14/18) showed significant improvement in virtue of Li-ESWT treatment (p=0.001). A significant improvement was observed in the percentage of “Yes” responses to SEPQ 2 and 3 in the Li-ESWT group vs. sham group from baseline to 7-week follow-up (91.3% vs. 69.4%; p=0.008 and 50.0% vs. 14.3%; p=0.002, respectively). No patients reported pain or other adverse events during treatment or follow-up.CONCLUSIONS: Thus, Li-ESWT could have a role in improving erectile function. Furthermore, it is safe. We believe that Li-ESWT is an attractive new treatment modality for patients with ED.

The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.

PURPOSE: There is substantial need for optimizing radiation protection in nuclear medicine imaging studies. However, the diagnostic reference levels (DRLs) have not yet been established for nuclear medicine imaging studies in Korea.MATERIALS AND METHODS: The data of administered activity in 32 nuclear medicine imaging studies were collected from the Korean Society of Nuclear Medicine (KSNM) dose survey database from 2013 and 2014. Through the expert discussions and statistical analyses, the 75th quartile value (Q3) was suggested as the preliminary DRL values. Preliminary DRLs were subjected to approval process by the KSNM Board of Directors and KSNM Council, followed by clinical applications and performance rating by domestic institutes.RESULTS: DRLs were determined through 32 nuclear medicine imaging studies. The Q3 value was considered as appropriate selection as it was generally consistent with the most commonly administered activity. In the present study, the final version of initial DRL values for nuclear medicine imaging in Korean adults is described including various protocols of the brain and myocardial perfusion imaging.CONCLUSION: The first DRLs for nuclear medicine imaging in Korean adults were confirmed. The DRLs will enable optimized radiation protection in the field of nuclear medicine imaging in Korea.

This article provides an overview of the developmental history and rationale of medical ethics to establish the code of ethics and professional conduct of the Korean Academy of Child and Adolescent Psychiatry (KACAP). Most medical professional organizations have their own codes of ethics and conduct because they have continuous responsibility to regulate professional activities and conducts for their members. The Ethics and Award Committee of the KACAP appointed a Task-Force to establish the code of ethics and conduct in 2012. Because bioethics has become global, the Ethics Task Force examined global standards. Global standards in medical ethics and professional conduct adopted by the World Medical Association and the World Psychiatric Association have provided the basic framework for our KACAP's code of ethics and professional conduct. The Code of Ethics of the Americal Academy of Child and Adolescent Psychiatry has provided us additional specific clarifications required for child and adolescent patients. The code of ethics and professional conduct of the KACAP will be helpful to us in ethical clinical practice and will ensure our competence in recognizing ethical violations.

Ectopic adrenocorticotropic hormone (ACTH) syndrome is caused most frequently by a bronchial carcinoid tumor or by small cell lung cancer. Medullary thyroid carcinoma (MTC) is a rare etiology of ectopic ACTH syndrome. We describe a case of Cushing syndrome due to ectopic ACTH production from MTC in a 48-year-old male. He was diagnosed with MTC 14 years ago and underwent total thyroidectomy, cervical lymph node dissection and a series of metastasectomies. MTC was confirmed by the pathological examination of the thyroid and metastatic mediastinal lymph node tissues. Two years after his last surgery, he developed Cushingoid features, such as moon face and central obesity, accompanied by uncontrolled hypertension and new-onset diabetes. The laboratory results were compatible with ectopic ACTH syndrome. A bilateral adrenalectomy improved the clinical and laboratory findings that were associated with Cushing syndrome. This is the first confirmed case of ectopic ACTH syndrome caused by MTC in Korea.

An inflammatory myofibroblastic tumor (IMT) is a rare disease entity reported to arise in various organs. It is thought to be a neoplastic or reactive inflammatory condition, controversially. The treatment of choice for myofibroblastic tumor is surgery, and recurrence is known to be rare. The optimal treatment method is not well-known for patients ineligible for surgery. We report a 47-year-old patient with aggressive recurrent IMT of the lungs. The patient had been admitted for an evaluation of back-pain two years after a complete resection of pulmonary IMT. Radiation therapy was performed for multiple bone recurrences, and the symptoms were improved. However the patient presented again with aggravated back-pain six months later. High-dose steroid and non-steroidal anti-inflammatory drugs were administered, but the disease progressed aggressively, resulting in spinal cord compression and metastasis to intra-abdominal organs. This is a very rare case of aggressively recurrent pulmonary IMT with multi-organ metastasis.

Dental implantation in the mandibular anterior region is considered a safe and reliable surgical procedure. On the other hand, several articles have reported that inadvertent hemorrhage of the sublingual artery can result in life-threatening airway obstruction. Surgical ligation under intubation or tracheostomy is the most widely used approach for controlling mouth floor bleeding in this highly vascular region. Nonetheless, surgically exploring the bleeding focus is difficult because of anatomical distortion followed by widespread edema and swelling. Since swelling of the mouth floor advances quickly, timely management is essential for favorable postoperative outcome. This paper reports a case of immediate hemorrhage control with angiographic embolization to perform rapid hemostasis before the ongoing swelling causes airway obstruction. Less invasive, angiographic embolization can prevent neurovascular damage during a surgical exploration of injured vascular structures on the mouth floor.
