Facial Fractures at the Armed Forces Capital Hospital of Korea: A 10-Year Study From 2013 to 2022.

The aim of this study was to analyze facial bone fractures at the Armed Forces Capital Hospital of Korea (AFCH) from 2013 to 2022. This review included individuals who visited AFCH for treatment. The inclusion criteria for the study were fractures resulting from external trauma, specifically coded as S02.1-4 and S02.6-9. The exclusion criteria comprised fractures caused by factors other than external trauma. This retrospective study of 178 facial bone fractures included 176 males (98.9%) and 2 females (1.1%) (22.5±5.1 years). The most common causes of injury were bumps (72.5%), followed by slips (7.3%), assaults (5.6%), and falls (5.1%). The majority of facial bone fractures occurred during sports activities (33.7%), training (31.5%), or everyday activities (28.7%). Nasal bone fractures were the most prevalent (47.7%), followed by fractures of the maxilla (19.2%), orbit (18.7%), mandible (10.3%), and zygoma (3.3%). The interval between the injury and hospital arrival was 6.0±8.0 days. Among the 164 patients, 110 (67.1%) underwent surgery. The overall complication rate was 8.9%. The highest complication rate was mandibular fractures (22.7%), followed by nasal bone fractures (9.8%). Among the 208 recorded facial bone fractures, 145 patients (69.7%) received treatment at AFCH, whereas 63 (30.3%) were treated in a civilian hospital; 59 patients (28.4%) by their own choice and 4 patients (1.9%) on a consignment basis. The average follow-up period was 202.0±183.2 days. The relatively high rate (28.4%) of treatment at civilian hospitals is attributable to legislation allowing injured soldiers the option to choose between military and civilian medical facilities.

Current Status of Cold Injuries in the South Korean Military Over the Past 5 Years: Analysis and Assessment Based on the 2023-2024 Surveillance System.

This study aimed to examine the prevalence of cold injuries and review the cold injury monitoring system in the South Korean military. This study conducted a retrospective and cross-sectional analysis using data from the Defense Medical Statistic Information System (DMSIS) on cold injuries among military personnel from 2018 to 2023. It incorporated findings from the Korean Armed Forces Medical Command's cold injury surveillance system and analyzed cases from the Armed Forces Capital Hospital, covering all branches of the military by status and rank. An analysis of cold injury in the South Korean military over the past 5 years revealed varying numbers of cases treated, from 799 in 2018-2019 to 467 in 2022-2023. According to the surveillance system in 2023-2024, the Army experienced the majority of these cases, with 94.5% of the total. The incidence per 1,000 personnel was the highest in the Army at 0.98 compared to the Air Force and Navy/Marine Corps. Rank-based analysis indicated the most affected were private first-class soldiers. Frostbite was the most frequent condition, alongside chilblains, hypothermia, and immersion injuries, with no marked difference in the type of illness across branches. The study underscores the need for focused prevention and treatment, particularly in the Army. By analyzing data from a newly implemented surveillance system, it revealed a higher incidence of frostbite and chilblains among lower ranks. The findings highlight the importance of targeted educational measures and enhanced response strategies to protect personnel against cold injuries.

Nursing Experience of New Nurses Caring for COVID-19 Patients in Military Hospitals: A Qualitative Study.

This qualitative study explored the experiences of new nurses with less than one year of clinical experience in caring for COVID-19 patients in a military hospital. In-depth interviews were conducted with six new nurses working in a negative-pressure isolation unit of the Armed Forces Capital Hospital. Data were analyzed using the phenomenological method proposed by Colaizzi, and 12 themes were derived and classified into four clusters: burden of nursing in isolation units; hardship of nursing critically ill patients; efforts to perform nursing tasks; positive changes through patient care. The participants were anxious while caring for COVID-19 patients with severe illness due to a lack of clinical experience. Furthermore, the wearing of heavy personal protective equipment impeded communication with patients, leading to physical and psychological exhaustion. However, they tried to utilize their own know-how and provide the best nursing care, resulting in them gaining confidence. Participants were able to think critically and took pride in being military nursing professionals. This study is meaningful as it provides insight into the experiences of new military nurses who were rapidly dispatched during a national medical crisis. The results can be applied to develop future strategies aimed at improving new nurses’ competency in military hospitals.

Diagnostic index for acute eosinophilic pneumonia without bronchoscopy in military smokers.

Background/AimsAcute eosinophilic pneumonia (AEP) is common among military smokers; however, bronchoscopy is required for the diagnosis. We aimed to derive and validate a scoring system to diagnose AEP without bronchoscopy.MethodsWe conducted a retrospective study including patients diagnosed with AEP or any other pneumonia among military smokers hospitalized in the Armed Forces Capital Hospital from 15 November 2016 through 25 December 2019. The patients were divided into derivation and validation groups according to their admission day. Patient symptoms, laboratory findings, and computed tomography findings were candidate variables. Least absolute shrinkage and selection operator (LASSO) regression was used to calculate the scores for each variable.ResultsAmong 414 patients, AEP was confirmed in 54 of 279 patients (19.4%) in the derivation group and in 18 of 135 patients (13.3%) in the validation group. Ten variables were selected using LASSO regression: new-onset or a recently increased smoking (≤ 4 weeks) (8 points), interlobular septal thickening (5 points), absence of sputum (3 points), ground glass opacity (3 points), acute onset (≤ 3 days) (2 points), dyspnea (2 points), chest pain (2 points), leukocytosis (2 points), bronchovascular bundle thickening (2 points), and bilateral involvement (2 points). The area under the receiver-operating characteristic curve of the score to diagnose AEP was 0.997 (95% confidence interval, 0.992 to 1.000) in the derivation group and 0.985 (95% confidence interval, 0.965 to 1.000) in the validation group.ConclusionsWe introduce a scoring system that can distinguish AEP from other types of pneumonia in military smokers without the need for bronchoscopy.

The Prevalence of Sexually Transmitted Infections and Sociosexual Behaviors in the South Korean Military Before and During the COVID-19 Pandemic.

ABSTRACTIntroductionThis study evaluated the epidemiological factors of sexually transmitted infections (STIs) among South Korean troops including the prevalence, therapeutic methods, and sexual risk behaviors.Material and MethodsThe medical records of the STIs diagnosed troops at the Armed Forces Capital Hospital (AFCH) for 36 months (between January 2018 and December 2020) were retrospectively reviewed. The data collection for the study began after obtaining research approvals from the institutional ethics committee of AFCH. The patients were classified into two subgroups, pre-coronavirus disease 2019 (COVID-19) and COVID-19 groups. The clinical parameters of the patients including STI-related symptoms and underlying diseases were analyzed. The sociosexual conduct of the two study groups was evaluated and compared by using a survey questionnaire.ResultsOverall, 138 STI patients with mean age of 21.2 years were included (pre-COVID-19: 106 patients/COVID-19: 32 patients). 32.6% of the patients received college education before the military service. Regarding previous history of STIs, 24 patients (17.4%) had previous experience of STIs, which occurred before participation in the current study. Initial urine analysis results showed that 95 (68.8%) and 79 patients (57.2%) showed pyuria and bacteriuria, respectively. Neisseria gonorrhoeae (29.7%) was the most commonly identified pathogen. Each pathogen was treated with the therapies recommended by the current treatment guidelines, and no patient showed any recurrence of the disease during follow-up. Both pre-COVID-19 (91.5%) and COVID-19 (93.8%) groups showed high rates of binge drinking during off-duty. The pre-COVID-19 group had a greater number of patients (21.7%) having multiple sex partners (during the past 12 months) than the COVID-19 group (15.6%). The COVID-19 group had 18.8% of the troops involved in sexual activity even after the onset of STI-related clinical symptoms, whereas the rate was significantly higher than 2.8% of the pre-COVID-19 group (P = .001). The COVID-19 groups showed a significantly higher number of patients (four patients, 12.5%) experiencing suicidal ideation than the pre-COVID-19 group (two patients, 1.9%) (P = .010). Both groups showed <40% of condom use rates at the last sexual intercourse.ConclusionThe soldiers with STIs showed high rates of binge alcohol consumption, while the rates of engaging in safe sex by using condoms are markedly low. Although the COVID-19 group was under influence of social distancing and military base lockdown, the soldiers’ sociosexual conduct was not significantly different in the pre-COVID-19 group. The importance of education on alcohol misuse and safe sexual relationships should be taken more seriously within the military.

Dermatofibrosarcoma Protuberans in Active Duty Military Personnel: A Case Report.

Dermatofibrosarcoma protuberans (DFSP) is an uncommon, soft tissue sarcoma with a high rate of local recurrence, low rate of distant metastasis, and infiltrative growth. We report two cases of DFSP in young active duty military personnel. Both cases underwent primary excision at the Armed Forces Capital Hospital with positive surgical margins and underwent re-excision at Samsung Medical Center. Dermatofibrosarcoma protuberans is a rare finding, and wide local excision with or without skin flap remains the procedure of choice. Awareness of DFSP in young patients is important for proper diagnosis and treatment and to achieve local control. Complete excision of the tumor with a clear surgical margin and thorough surveillance after surgery are recommended for service members to maintain their active duty status and to prevent ineffective combat conditions.

Association between peripheral blood/bronchoalveolar lavage eosinophilia and significant oxygen requirements in patients with acute eosinophilic pneumonia

BackgroundWe investigated the association between a combination of two markers, peripheral (PEC) and bronchoalveolar lavage (BAL) eosinophil percentage (BEP), and oxygen requirements in patients with acute eosinophilic pneumonia (AEP).MethodsWe retrospectively reviewed the medical records of patients with AEP treated at the Armed Forces Capital Hospital between May 2012 and May 2017. We used correlation analyses to assess the association between PEC/BEP and clinical outcomes in AEP patients. Receiver operating characteristic (ROC) curve analyses were used to calculate the cut-off value for BEP that categorised patients requiring a significant oxygen supply. The BAL/blood eosinophil (BBE) score was introduced to stratify patients with peripheral eosinophilia and elevated BEP. Clinical characteristics and outcomes were compared between the different groups. Multiple logistic regression was performed for significant oxygen requirements using two different models using age, C-reactive protein (CRP), smoking duration, and BBE score (model 1) and age, CRP, BEP, and PEC (model 2).ResultsAmong the 338 patients, 99.7% were male, and their mean age was 20.4 ± 1.4 years. Only 0.6% of patients were never smokers and the mean number of smoking days was 26.2 ± 25.4. Correlation analyses revealed that both the PaO2/FiO2 ratio and duration of oxygen supply were associated with BEP. ROC curve analyses indicated a cut-off level of 41.5%. Patients with a high BBE score had favourable outcomes in terms of hypoxemia, hospital days, intensive care unit admission, oxygen supply days, and steroid treatment days. Multiple logistic regression revealed that BEP and BBE score tended to be associated with significant oxygen requirements.ConclusionsIn this study, we revealed that both peripheral and BAL eosinophilia is associated with favourable outcomes in AEP patients.

The effects of patient education on patient safety: can we change patient perceptions and attitudes?: Lessons from the Armed Forces Capital Hospital in Korea.

Strategies to promote patient involvement in medical error prevention have been implemented, but little is known about the effects of education on changes in perceptions and attitudes about patients' own safety. We administered a survey to military personnel admitted to the Armed Forces Capital Hospital. Responses were classified according to perception and attitude. Single military hospital in Korea. A total of 483 completed surveys were included in our study; 252 of the respondents received safety education at admission. We provided educational program material to one-half of the patients at admission (intervention group). The other one-half of patients received no safety education (non-intervention group). We then performed two rounds of a self-administered survey, based on whether the patient received patient safety education. Cronbach's alpha was calculated to determine scale score reliability. Regression analysis was used to evaluate associations between education and change in scores. Scores for perception and attitude were greater in the intervention group. The results of the regression analysis revealed that compared with the non-intervention respondents, the respondents who received education had higher perception (estimate: 7.809, P < 0.0001) and attitude scores (estimate: 5.539, P < 0.0001). Our study results suggested that patient education was associated with higher scores in both perception and attitudes about safety. To improve patient engagement in this area, efficient methods that encourage patient empowerment should be developed. Specialized health care providers who provide patient level education are needed to achieve a satisfactory patient safety climate.

Comparison of Various Methods of Mesoappendix Dissection in Laparoscopic Appendectomy

Although laparoscopic appendectomy is one of the most commonly performed operations, operation procedures vary widely according to the surgeon. In particular, various methods using different instruments have been used for mesoappendix dissection, such as endostapler, endoclip (EC), Harmonic(®) (Ethicon Endo-Surgery, Cincinnati, OH) scalpel (HS), electrocautery, and LigaSure™ (Covidien, Mansfield, MA). Here we compared the results of mesoappendix dissection by EC, HS, and monopolar electrocautery (ME). The study was performed on 1178 patients who received laparoscopic appendectomy at the Armed Forces Capital Hospital, Seongnam, Korea, from January 2003 to April 2013. Patients receiving mesoappendix dissection involving EC, HS, or ME were enrolled. Patient demographics, pathology of appendix, and perioperative data including operation time, hospital stay, and complications were analyzed. A theoretical model of disposable cost was constructed for each method to compare cost-effectiveness. The average operation time for the 1178 patients was 58.0±24.9 minutes for the EC group, 51.4±25.5 minutes for the HS group, and 57.7±25.7 minutes for the ME group. The time for the HS group was significantly shorter. Hospital stay and complication rates did not differ. Disposable costs were 620,350 South Korean won (KRW) (571 U.S. dollars) for the EC group, 1,041,230 KRW (959 U.S. dollars) for the HS group, and 491,230 KRW (452 U.S. dollars) for the ME group. The operation time of ME was similar to that of EC. Although HS had a significantly shorter operation time, the operation time of all three methods was under 60 minutes. All three methods had acceptable complication rates. ME was the most cost-effective method and, given the other similarities, can be recommended for mesoappendix dissection in laparoscopic appendectomy.

Clinical and Radiological Characteristics of 2009 H1N1 Influenza Associated Pneumonia in Young Male Adults

PurposePneumonia was an important cause of death in 2009 H1N1 influenza pandemic (pH1N1). Clinical characteristics of pH1N1 have been described well, but discriminative characteristics suggesting pH1N1 infection in pneumonia patients are not evident today. We evaluated differences between clinical and radiologic characteristics for those associated and not associated with pH1N1 influenza during the pandemic period.Materials and MethodsWe reviewed all patients with pneumonia who visited the Armed Forces Capital Hospital between July 2009 and February 2010. During this period, all pneumonia patients were tested for pH1N1 by reverse transcription-polymerase chain reaction (RT-PCR) using nasopharyngeal specimens.ResultsIn total, 98 patients with pneumonia were enrolled. Their median age was 20 years and all patients were males. Forty-nine (50%) of patients had pH1N1 infection and the others (50%) had negative results in pH1N1 RT-PCR. Patients with pH1N1 infection complained of dyspnea more commonly (83.3% vs. 29.0%; p<0.001), had higher Acute Physiology and Chronic Health Evaluation (APACHE) II scores [5 (range, 0-12) vs. 3 (range, 0-11); p<0.01], fewer days of prehospital illness [2 (range, 0-10) vs. 4 (range, 0-14); p=0.001], and a higher chance of bilateral infiltrates on chest X-ray (CXR) (67.3% vs. 14.3%; p<0.001) and ground-glass opacity (GGO) lesions on computed tomography (CT; 48.9% vs. 22.0%; p<0.001) than patients without pH1N1 infection.ConclusionDyspnea, bilateral infiltrates on CXR, and GGO on CT were dominant features in pH1N1-associated pneumonia. Understanding these characteristics can help selection of patients who require prompt antiviral therapy.

Fraction of Exhaled Nitric Oxide in Patients With Acute Eosinophilic Pneumonia

Acute eosinophilic pneumonia (AEP) is an idiopathic disease characterized by pulmonary eosinophilia. Because the fraction of exhaled nitric oxide (Feno) is a surrogate of eosinophilic inflammation, we evaluated the levels, changed treatments, and the diagnostic role of Feno in patients with AEP. Between June 2010 and March 2011, we prospectively enrolled patients at the Armed Forces Capital Hospital who had pulmonary infiltrates and a febrile illness and who were clinically suspected to have AEP. We measured Feno twice at the initial visit (pretreatment) and 2 weeks after the initial measurement (posttreatment). A total of 60 subjects were enrolled, and 31 were given a diagnosis of AEP. The pretreatment Feno levels of the patients with AEP were significantly higher than those of the patients without AEP (median, 48 parts per billion [ppb] [range, 10-138] vs 14 ppb [range, 5-41]; P < .001). The cut-off value (23.5 ppb) showed that the maximal area under the receiver operating characteristic curve predicted AEP with a sensitivity of 0.87 and a specificity of 0.83. The posttreatment Feno levels decreased significantly in the patients with AEP, and the levels were similar to the patients without AEP (median, 19 ppb [range, 7-44] vs 14 ppb [range, 1-58]; P = .21) The Feno level was significantly higher in patients with AEP than in those without AEP. Feno measurement can be used as a diagnostic tool to differentiate patients with AEP from those without AEP. ClinicalTrials.gov; No.: NCT01152424; URL: www.clinicaltrials.gov.

Multidrug-resistant Pulmonary Tuberculosis Among Young Korean Soldiers in a Communal Setting

The goal of this study was to evaluate the prevalence of first-line anti-tuberculosis drug resistance and risk factors associated with multidrug-resistant tuberculosis (MDR TB) among young soldiers in the Korean military, which has a strict tuberculosis control program. All patients with culture-confirmed pulmonary tuberculosis during their service at the Armed Forces Capital Hospital from January 2001 to December 2006 were enrolled in the study. Drug resistant Mycobacterium tuberculosis was isolated from 18 patients (12.2%) and multidrug-resistant M. tuberculosis was isolated from 12 patients (8.1%). Previous treatment of tuberculosis and the presence of a cavity on the patient's chest computed tomography scan were associated with MDR TB; military rank, smoking habits, and positive acid-fast bacilli smears were not associated with MDR TB. In a multiple logistic regression analysis, previous treatment of tuberculosis was a significant independent risk factor for MDR TB (odds ratio 6.12, 95% confidence interval 1.53-24.46). The prevalence of drug resistant tuberculosis among young soldiers in the Korean military was moderately high and the majority of resistant cases were found in patients who had undergone previous treatment of tuberculosis. Based on our results, we suggest that relapsed tuberculosis cases within communal settings should be cautiously managed until the drug susceptibility tests report is completed, even if previous treatment results were satisfactory.

Incidence and Seroprevalence of Hepatitis A Virus Infections among Young Korean Soldiers

This study was performed to determine the incidence and seroprevalence of hepatitis A virus (HAV) infections in young soldiers in the Republic of Korea Army. From January 2000 through December 2004, a total of 147 hepatitis A cases were reported to the Armed Forces Medical Command. The annual incidence rates were 7.4 per 100,000 persons in 2000, 1.6 in 2001, 4.4 in 2002, 9.8 in 2003, and 6.2 in 2004, based on the reported cases among approximately 500,000 soldiers. All patients were males with a median age of 21 yr (range, 19-27). The most common symptom was nausea (86.5%), and all patients had recovered without complications. In addition, in order to evaluate the seroprevalence of HAV infection in young adults, serum samples were obtained from randomly selected young subjects among those who had been admitted to the Armed Forces Capital Hospital from September 2005 to February 2006. A total of 200 subjects were enrolled in the study to analyze the anti-HAV immune status. The overall anti-HAV IgG seropositive rate was 2% (4/200, 95% CI, 0.60-5.21%). Given the changing epidemiology of the disease and the associated increase in morbidity, it was suggested that the routine HAV vaccination for Korean military personnel might be necessary.
