A 3-month-old Korean native cattle (Hanwoo) calf with difficulty taking normal posture and an inability to rise was referred for a definite diagnosis and active treatment, including surgery. The calf had a history of an accident in which both hind limbs were trapped in a barn structure. After admission, a "rabbit leg" posture was observed, a typical sign of gastrocnemius muscle rupture, and both digits were knuckled downward like they were trying to grip the ground. This was considered to be a result of the superficial digital flexor not rupturing but only the gastrocnemius muscle rupturing. Physical examination revealed laceration of the metatarsus and firmness behind both stifle joints which were presumed to be the sites of gastrocnemius muscle rupture. Skeletal abnormalities, including fractures, were ruled out by radiography. Based on these findings, the patient was diagnosed with bilateral gastrocnemius muscle rupture, and surgery was performed to reconnect the head of the ruptured muscle. Because the rupture occurred perpendicular to the muscle direction, the locking loop technique, a method of suturing severed tendons, was used to reduce the tension. After surgery, the cast was used to prevent further injuries and promote voluntary rehabilitation. Follow-up was completed, with the calf showing normal posture and gait 112 days after surgery. This is the first case report in the Republic of Korea describing the successful diagnosis and treatment of bilateral gastrocnemius muscle rupture in a calf.

Objectives: This analysis details the characteristics of dental trauma in South Korea during the coronavirus disease 2019 (COVID-19) (DC) pandemic and compares them in patients before and after COVID-19 (BC and AC, respectively). Materials and Methods: Data were collected from medical records of patients who visited Seoul National University Bundang Hospital's Emergency Dental Care Center during three 12-month periods: BC, DC, and AC (BC from March 1, 2019 to February 29, 2020; DC from March 1, 2020 to February 28, 2021; AC from March 1, 2022 to February 28, 2023). A retrospective review was conducted to investigate patient age, sex, time of visit, cause, and diagnosis. The study included 1,544 patients: 660 BC, 374 DC, and 510 AC. Results: Significant difference in age and sex was not observed among the three periods; 1-9 years of age was the largest group (38.3% in BC, 29.6% in DC, and 27.8% in AC), and the percentage of male patients was greater than of female patients (male proportion as 63.5% in BC, 67.4% in DC, and 64.9% in AC). The number of patients generally peaked at a Saturday night in spring (for BC: May, Saturday, 18:00-19:59; for DC: March, Saturday, 18:00-19:59; for AC: April as the second most (October as the most peaked), Saturday, 20:00-21:59). The primary etiology of the dental trauma was identical in the three periods: falls, followed by sports. The most frequent diagnosis was laceration, followed by tooth avulsion and jaw fracture. Conclusion: Significant differences were not found between the characteristics and patterns of dental trauma in the BC, DC, and AC periods. However, due to the pandemic and social distancing, activities decreased and associated dental trauma-related incidents declined.

The present study was performed to evaluate the function of the mandible according to the pattern of fracture and treatment methods of condylar fractures of the mandible and help operators in making a treatment plan. Sixty patients (average follow-up period was $7.8{\pm}9.4$ months) who were treated for condylar fracture from June, 2002 to May, 2006 at the Department of Oral and Maxillofacial surgery, Chonnam National University Hospital were reviewed. The common causes of the condylar fracture were traffic accident and fall-down (35.0%). In concomitant injuries, laceration was 46.7% and the fracture of the mandibular symphysis was highest incidence (60.0%). The common site of the fracture was the condylar head (47.8%), followed by subcondyle (36.2%) and condylar neck (15.9%). Under 15 years old patients, the closed reduction was performed in 87.5% out of the patients. All of the condylar fragments were fixed to the mandible with titanium miniplates in cases of open reduction. The mean period of intermaxillary fixation (IMF) was $14.2{\pm}6.5$ days in closed reduction and $10.0{\pm}4.2$ days in open reduction. The old patient with bilateral condylar head fractures, who were treated by closed reduction with IMF for 3 weeks, showed the limitation of mandibular movements. But, there was no significant different results between open reduction and closed reduction with the respect of the Helkimo's mandibular mobility index and clinical dysfunction index (DI). Complications, such as fibrous ankylosis and resorption of the mandibular condyle, were not observed in all patients. These results suggest that the good results can be obtained by closed reduction with proper IMF periods and functional exercise in most condylar fractures of the mandible except severely displaced extracapsular fractures.

An investigation on various causes of milking disturbances resulting from injuries and abnormalities of mammary system were made in 2,179 Holstein cows. To perform this investigation, 69 dairy farms of the suburban area of Seoul city, Gyeonggi-do and Chungnam provinces were andomly selected and subjected. Diagnosis was made by means of inspection and palpation of teat, insertion of teat canula, checking milk machines, anamneses and farm records. This investigation was, actively done from March 1977 to February 1979, The results obtained were summerized as follows; 1. It was found that 446 cows, accounting for 20.48% of 2,179 cows inspected, had supernumerary teats. Among them 53.59% had one, 43.72% had two, 2.47% had three, and 0.22% had four supernumerary teats, respectively. 2. Dry off quarters were found in 158 quarters which turned out to be 1.8% of 8,716 quarters inspected. Among dry off quarters, 62.02% seemed to be caused by mastitis, 30.37% by acquired teat obstructions, and 7.59% by congenital blind teats and glands respectively. 3. Teat sphincter stenosis was found in 154 teats of 50 cows, which represents 1.76% of 8,716 teats and 2.29% of 2,179 cows inspected, respectively. Among 154 teats with teat sphincter stenosis, 138 teats (85.7%) of 33 cows were found to be congenital and revealed highest incidence. 4. Loose sphincter was found in 78 teats of 36 cows, which figure 0.89% of 8,7l6 teats and 1.69% of 2,179 cows inspected, respectively. Among 78 teats with loose sphincter, 52 teats (66.66%) of 13 cows were found to be congenital and revealed highest incidence. 5. Injured teat tip caused by over milking of milk machine, was found in 229 teats of 156 cows, which figure 2.63% of 8,716 teats and 7.15% of 2,179 cows observed, respectively. 6. Other miscellaneous injuries and congenital abnormalities of teats and udders were diagnosed as follows: The teat laceration was found in 34 teats (0.39% of 8,716 teats), fissure of teat skin in 24 teats (0.28% of 8,716 teats), stricture of teat cistern in 21 teats (0.24% of 8,716 teats), teat fistula in 12 teats (0.14% of 8,716 teats), papillomas on testes in 8 teats (0.09% of 8,716 teats). Knothole orifice in 7 teats (0.08% of 8,716 teats), subcutaneous abscess of udder in 5 quarters (0.05% of 8,716 teats), membraneous obstruction of teat cistern in 4 teats (0.05% of 8,716 teats), and congenital short teat in 8 teats (0.09% of 8,716 teats), respectively.

This is a clinical study on 235 inpatients who sustained a total of 350 mandibular fractures and who were treated in our department during the period of Oug., 1989 through Dec., 1993. The results obtained are as follows : 1. The mumber of patients has not been increased year after year. In respect of incidence, there were the highest frequency as 67 patients(28.5%) in 1991 and the least frequency as 16 patients(6.8%) in 1989 and the highest frequency as 28 patients(11.9%) in October and the least frequncy as 12 patients(5.2%) in February. 2. The age frequency was the highest in the second decade(30.6%). The youngest patient was 8 months and the eldest patient was 80 years and mean age was 27.8 years. The ratio of men to Wemen was 4 : 1. 3. The most frequent cause was fall down as 86 patients(36.6%) and the next was fist blow 4 as 75 patients(31.9%), traffic accident as 56 patients(23.9%) in order. 4. The most common location was symphysis as 141 numbers(40.3%) and the next was condyle as 96 numbers(27.4%), angle as 94 numbers(26.8%), body as 14 numbers(4.0%) in order. The sum of fracture sites were 350 and there were 1.49 fracture sites per one patient and multiple fractures occured in 100 patients(40.5%) of the 235 patients. The ratio of Left to Right except for symphysis was 1.71 : 1. 5. Among the 333 associated injuries, facial laceration was 136(57.9%) and tooth injury was 58(24.7%) and extremity was 31(13.2%). 6. Among the 350 mandibular fractures, complications after treatment occured in 51(14.6%) and infection as 20(5.7%) was the most frequent complication. 7. In respect of treatment of mandibular fracture, close reduction was 64 patients(27.2%) and open reduction was 164 patients(69.8%) and other were 7 patients(3.0%) of all and so open reduction was the most common in type of treatment.

어린이는 쉽게 넘어지거나 부딪혀 구강안면부의 손상을 흔히 경험하며, 응급치료를 필요로 한다. 이러한 환자들에서는 공포와 불안으로 인해 협조도가 불량해지게 된다. 케타민은 일반 응급실에서 어린 환자의 치료와 검사를 위한 진정제로 잘 알려져 있다. 본 연구에서는 원주 세브란스 기독병원 응급실에서 케타민을 이용한 진정법을 시행한 현황에 대해 알아보았다. 2010년 1월에서 2014년 5월까지 치과적 응급처치를 위해 의뢰된 만 18세 이하의 환자들의 기록이 수집되었으며, 연령, 성별, 시행된 치과적 치료, 케타민 진정법 시행 여부에 대한 자료를 분석하였다. 총 659명의 소아 환자가 치과적 응급처치를 필요로 하였으며, 이중 118명이 케타민 진정법이 시행되었다. 조사 결과 열상의 봉합을 시행한 환자에서 진정법이 더 많이 시행되었고, 연령이 어릴수록 진정법이 시행되었던 상관성이 확인되었다. 케타민 진정법은 치과의사 단독으로 사용하지 않아야 하지만, 응급실에서 1차 진료를 담당하는 치과의사는 케타민 진정법이 적용된 환자들을 쉽게 접할 수 있다. 따라서, 응급실에서 근무하는 치과의사는 케타민의 임상적 효과, 고려사항, 그리고 발생 가능한 합병증 및 대처 방안에 대해 숙지하고 있어야 할 것으로 사료된다.

Purpose: The object of this study is to compare the patient satisfaction in the view of scarring, cost, and hospital stay between the conventional suture method and a method using Histoacryl$^{(R)}$ (2-N-butylcyanoacrylate) adhesive for treating facial lacerations in the emergency department. Method: This study is a randomized prospective trial, which was conducted from December 2009 to January 2010. The participants include 109 patients who visited the emergency room in Deajon Eulji Medical Center. The ages ranged from 1 to 59 (mean age of 18.7), and all had facial lacerations of less than 3 cm. In order to treat the facial lacerations, an emergency medicine doctor used tissue adhesive (2-N-butylcyanoacrylate, Histoacryl$^{(R)}$) for 41 patients in the experimental group, and a plastic surgeon performed conventional suturing for 68 patients in the control group. The ER-stay and the primary treatment fee were compared in the two groups, and the scarring was evaluated 10 to 11 months from suturing by using the Modified Hollander Method and the 10-cm scaled VAS (visual analogue scale: score 0=no scar, score 10=very severe scar) Result: The ER stay was 76 minutes for the experimental group and 107 minutes for the control group, showing that statistically significantly less time of 31 minutes was taken in the experimental group. The cost of the experimental group was 40000 won (50.1%) more expensive than the control group, with an average cost of 121900 won for the experimental group and 81200 won for the control group. As for scar evaluation, 10.56 months after suturing, the experimental group showed a better result with a score of 2.6 compared to a score of 3.4 in the control group; however, this difference was not statistically significant ($p$ <0.05). As to a detailed evaluation of scar characteristics, the experimental group had a statistically significantly better result in scar elevation, with a score of 0.6 compared to a score of 1.65 for the control group. Conclusion: If appropriate patients are selected, the method using tissue adhesive directly applied by an EM doctor not only decreases ER stay but also creates similar patients satisfaction, with statistically better result in scar elevation, compared to the conventional suture method; thus, ultimately general patient satisfaction is increased.

배경: 다발성 외상환자는 교통사고, 산업재해, 우발적사고, 폭력 등의 증가로 최근 증가 추세에 있다. 다발성 외상은 심장, 폐, 대혈관 등의 흉부외상을 포함하는 경우가 많으며 이때는 환자의 생명을 위협할 수 있으므로 적절한 진단과 치료가 필요하다. 대부분의 흉부외상은 보존적 치료와 흉관 삽관술과 같은 간단한 외과적 시술 만으로 만족할 만한 치료효과를 보이지만 적절한 시기에 개흉술을 시행함으로써 환자의 생명을 구할 수 있는 경우가 있어 그 적응증 이나 시기의 판단에 있어서 경험있는 흉부외과 의사의 역할이 필요하다. 대상 및 방법: 저자는 다발성 외상 후 흉부개흉술이 필요했던 70례에 대하여 분석하였다. 환자들의 평균 나이는 35.6세 남녀비는 3.4:1이었다. 손상의 기전은 주로 교통사고, 추락사고, 자상이었다. 결과: 흉부손상의 가장 일반적인 유형은 혈흉이며, 두 번째는 횡격막 파열이었다. 환자의 60%에서 골절을 동반 하고 42.9%에서 복부손상을 37.1%에서 두부손상을 동반하고 있었다. 개흉술을 시행한 이유로는 출혈교정 혹은 지혈이 48.6%, 횡격막손상의 복구가 35.7%였으며, 폐 열상 봉합이 25.7% 였으며, 흉부 손상으로 인한 수술외에도 비장적출술(14.3%), 간엽절제술(8.6%) 간 열상 복구(5.7%)를 시행하였다. 수술후 합병증으로는 무기폐(8.6%), 창상감염(8.6%), 폐렴(4.3%)이었다. 수술후 6명의 환자가 사망하였고 수술사망율은 8.6%였다. 사망의 원인으로는 호흡부전증(2례), 급성 신기능부전증(2례), 패혈증(1례), 저혈량성 쇽(1례)이었다.

이 연구는 수부손상의 발생요인과 진료양상을 분석함으로써 수부손상의 예방과 수부전문병원의 진료 효율성 제고를 위한 기초정보를 제공하기 위해 수행되었다. 분석을 위해 서울시 소재 S병원에 2008년 1월 1일부터 2010년 12월 31일까지 최근 3년간 내원한 환자 중 수부손상 환자 총 2,461명의 환례를 전수 조사 하였다. 분석결과는 다음과 같다. 첫째, 수부손상 환자의 인적특성군 별로 수부손상 발생의 시기, 장소, 원인별 빈도와 유의한 차이를 보였다. 남자가 여자에 비해, 노년기환자가 영유아기환자에 비해 재원기간은 긴 반면 일평균진료비는 낮았으며, 국민건강보험환자가 자동차보험과 산재보험환자에 비해 재원기간은 짧은 반면 일평균진료비는 높았다. 둘째, 수부손상 환자의 인적특성변수와 수부손상의 발생양상변수는 재원기간과 일평균진료비, 건당 평균진료비에 유의한 영향을 보였다. 수부손상환례의 재원기간이 건당진료비의 크기를 결정하는 요인이기 때문에 재원기간에 정(正)의 영향을 미치거나 재원기간에 유의한 차이가 있는 남성, 노년기, 산재보험환자의 기계 작업도구에 의한 환례, 절단 결출상의 환례, 그리고 이식술의 재원기간을 단축하는 방안이 치료 효율을 위해 긴요한 것으로 보인다. 이에 수부손상환례의 조속한 진단 치료로 재원기간 단축 등을 통해 수부전문병원의 진료효율성 제고방안을 다양한 차원에서 강구할 것을 제언한다.
