Purpose: Transversus abdominis plane (TAP) block is a promising technique for postoperative pain control. In this study, we aimed to evaluate the efficacy of the TAP block in managing postoperative pain after laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. Methods: In this retrospective study, medical records of patients who had received ultrasonography-guided TAP blocks after surgery from January 2019 to August 2023 were reviewed and compared with those of patients who had not received. Propensity score matching was controlled for age as a confounder. Postoperative pain levels were measured using the numeric rating scale (NRS). Results: After matching, 95 patients were included in each group. The TAP block group (2.7 vs. 4.0, P < 0.001) had significantly lower NRS scores immediately and early postoperative pain than the control group (1.9 vs. 2.5, P < 0.001). However, there was no significant difference between the 2 groups in terms of postoperative complications (P > 0.05). Conclusion TAP block is effective and safe for managing immediate and early postoperative pain in laparoscopic TEP inguinal hernia repair and does not increase the risk of complications.

Purpose: Wrestlers have a lot of direct skin-to-skin contact between wrestlers during matches, and many studies show that wrestlers are vulnerable to the spread of skin infections. However, there have been few studies on skin infections in Korean wrestlers. The purpose of this study was to compare the characteristics of skin diseases in wrestlers and other athletes. Methods: Athletes who visited for skin diseases in the Department of Family Medicine in the Jincheon National Training Center in 2018 were investigated. We calculated the duration of skin disease per training period (DSD/TP) as the number of visits×7 days×1,000/official training days. Athletes with a DSD/TP above the median value or equal to were defined as the high DSD/TP group, and the others were defined as the low DSD/TP group. A chi-square test was used to compare the odds ratio [OR] for these groups about infectious and noninfectious skin diseases. Results: Thirty wrestlers and 89 other sports players visited the infirmary with skin diseases. The probability of belonging to the high DSD/TP group was significantly higher when the wrestlers visited for skin infections than the other athletes (OR, 7.714; 95% confidence interval [CI], 2.699–22.048). However, there was no significant difference in noninfectious skin diseases between wrestling and other sports (OR, 0.569; 95% CI, 0.246–1.320). Conclusion This is the first study that shows Korean national wrestlers with skin diseases receive more treatment for infectious skin diseases than other sports. This study can provide important information on the prevention of wrestlers for skin infections.

Pediatric inguinal hernia is the most prevalent surgical condition in children and accounts for nearly half of all pediatric surgical procedures performed. The primary cause of pediatric inguinal hernia is a patent processus vaginalis (PPV), which often requires surgery. Traditionally, the standard treatment involved high ligation of the PPV through a small incision combined with laparoscopic methods. These minimally invasive techniques offer improved cosmetic outcomes and are increasingly favored in clinical practice. This review aimed to present the current surgical techniques for pediatric inguinal hernia treatment, with a focus on various laparoscopic approaches. Additionally, it discusses the optimal timing for treating hernias in neonates and preterm infants as well as specialized surgical strategies for adolescent patients. This review highlights advancements in surgical methods that accommodate the specific needs of different age groups within the pediatric population.

Purpose: Sirolimus has emerged as a safe and effective treatment for complicated lymphatic malformations (LMs). We aim to prove the effectiveness and safety of sirolimus as a therapeutic option for patients with complicated LMs. Methods: Fifty-eight patients with complicated LMs treated with sirolimus for at least 6 months at multicenter between July 2018 and January 2023 were enrolled. All patients were administered oral sirolimus starting at 0.8 mg/m 2 every 12 hours, with target serum concentration levels of 8–15 ng/mL. Evaluation for clinical symptoms and LMs volume on MRI were reviewed to assess treatment response and toxicities. Evaluation of disease response was divided into 3 values:complete response, partial response (significant, moderate, and modest), and progressive disease. Results: The median age at the initiation of sirolimus treatment was 6.0 years (range, 1 month–26.7 years). The median duration of treatment was 2.0 years (range, 6 months–4.4 years). The most common lesions were head and neck (25 of 58, 43.1%). Forty-six patients (79.3%) demonstrated a reduction in LMs volume on MRI or improvement of clinical symptoms including 2 complete responses. The young age group and the patients who underwent few prior therapies showed better responses. None of the patients had toxicities attributable to sirolimus with a Common Terminology Criteria for Adverse Events grade of ≥3. Conclusion Oral sirolimus treatment brought a successful outcome without severe adverse effects. It could be the firstline therapy, especially for the young age group of complicated LMs, and an additional option for refractory lesions that did not respond to conventional treatment.

The Korea Nurses’ Health Study (KNHS) is an ongoing, large-scale, prospective cohort study of women nurses, focusing on the effects of occupational, environmental, and lifestyle factors on the health of women. The first KNHS survey was performed in 2013-2014 (n=20,613). As of December 2023, 11 follow-up surveys have been conducted. Participants who were pregnant were asked to participate in the early pregnancy survey (n=2,179) and postpartum survey after giving birth (n=2,790). The main variables included socio-demographic, work-related, lifestyle, physical, mental, and women’s health factors. Blood, urine, and toenail samples were collected from a participant subgroup of the first survey (n=1,983). The subgroups of the second survey completed a food frequency questionnaire in 2019 (n=300) and 2021 (n=871). In 2020, a subgroup of the first survey answered a coronavirus disease 2019-related survey (n=975). To examine various health-related factors in young adults, new participants were added to the KNHS cohort in the 11th (n=1,000) and 12th (n=1,002) surveys. The KNHS cohort will help identify health and illness determinants in Korean women. Data can be accessed at https://coda.nih.go.kr/frt/index.do.

Background: Human adenovirus (HAdV) is a common cause of acute respiratory disease (ARD) and has raised significant concerns within the Korean military. Here, we conducted a comprehensive epidemiological analysis of HAdV-associated ARD by evaluating its prevalence, clinical outcomes, and prognosis. Methods: We reviewed data from multiple sources, including the New Defense Medical Information System, Defense Medical Statistical Information System, Ministry of National Defense, Army Headquarters, Navy Headquarters, Air Force Headquarters, and Armed Forces Medical Command. We analyzed data of patients who underwent polymerase chain reaction (PCR) testing for respiratory viruses between January 2013 and July 2022 in all 14 Korean military hospitals. The analysis included the PCR test results, demographic characteristics, health care utilization, and prognosis including types of treatments received, incidence of pneumonia, and mortality. Results: Among the 23,830 individuals who underwent PCR testing at Korean military hospitals, 44.78% (10,670 cases) tested positive for respiratory viruses. Across all military types and ranks, HAdV was the most prevalent virus, with a total of 8,580 patients diagnosed, among HAdV, influenza virus, human metapneumovirus, human parainfluenza virus, and human respiratory syncytial virus. HAdV-infected patients exhibited higher rates of healthcare use compared to non-HAdV-infected patients, including a greater number of emergency visits (1.04 vs. 1.02) and outpatient visits (1.31 vs. 1.27), longer hospitalizations (8.14 days vs. 6.84 days), and extended stays in the intensive care unit (5.21 days vs. 3.38 days).Furthermore, HAdV-infected patients had a higher proportion of pneumonia cases (65.79%vs. 48.33%) and greater likelihood of receiving advanced treatments such as high flow nasal cannula or continuous renal replacement therapy. Conclusion Our findings indicate that HAdV posed a significant public health concern within the Korean military prior to the coronavirus disease 2019 (COVID-19) pandemic. Given the potential for a resurgence of outbreaks in the post-COVID-19 era, proactive measures, such as education, environmental improvements, and the development of HAdV vaccines, are crucial for effectively preventing future outbreaks.

Background: To evaluate the therapeutic effectiveness and safety of a neurofeedback wearable device for stress reduction. Methods: A randomized, double-blind, controlled study was designed. Participants had psychological stress with depression or sleep disturbances. They practiced either neurofeedback-assisted meditation (n = 20; female, 15 [75.0%]; age, 49.40 ± 11.76 years) or neurofeedback non-assisted meditation (n = 18; female, 11 [61.1%]; age, 48.67 ± 12.90 years) for 12 minutes twice a day for two weeks. Outcome variables were self-reported questionnaires, including the Korean version of the Perceived Stress Scale, Beck Depression Inventory-II, Insomnia Severity Index, Pittsburgh Sleep Quality Index, and State Trait Anxiety Index, quantitative electroencephalography (qEEG), and blood tests. Satisfaction with device use was measured at the final visit. Results: The experimental group had a significant change in PSS score after two weeks of intervention compared with the control group (6.45 ± 0.95 vs. 3.00 ± 5.54, P = 0.037). State anxiety tended to have a greater effect in the experimental group than in the control group (P = 0.078). Depressive mood and sleep also improved in each group, with no significant difference between the two groups. There were no significant differences in stress-related physiological parameters, such as stress hormones or qEEG, between the two groups.Subjective device satisfaction was significantly higher in the experimental group than in the control group (P = 0.008). Conclusion Neurofeedback-assisted meditation using a wearable device can help improve subjective stress reduction compared with non-assisted meditation. These results support neurofeedback as an effective adjunct to meditation for relieving stress.
