A 3-year-old male Thoroughbred serving as a Korean racehorse named RAON PORTEOUS presented with acute lameness concomitant with edema and fever in the right carpal joint after completing a horse race. Through radiological examination using lateromedial oblique, flexed lateromedial oblique and dorsopromixal-dorsodistal oblique views, the horse was diagnosed with a slab fracture in the 3^rd carpal bone of right forelimb. The fracture was surgically approached and corrected by applying 4.5 mm leg screw fixation during surgery. At eight months post-surgery, the horse was able to return to racing and has had successful racing performances with two wins and several prizes in the last 8 months. This is the first reported case of the successful use of lag screw fixation surgery in Korea with the horse showing complete recovery from a severe injury that is often considered fatal in a racehorse.

Acute lateral ankle sprain, which is the most common musculoskeletal injury, can be treated effectively with appropriate evidence-based initial care using PRICE (protection, rest, ice, compression, and elevation) and functional rehabilitation. Many systemic reviews reporting a high-level of evidence supporting the clinical usefulness and necessity of primary surgical repair for acute lateral ankle sprain have been insufficient. Regardless of the severity of ligament complex injuries, the surgical treatment for acute lateral ankle sprain without concomitant pathologies is not recommended and should be considered only in young professional athletes with complete ligament rupture (grade III) and severe instability.

Traumatic flank hernia (TFH) is rare and prone to recurrence, which makes appropriate treatment challenging. No current guidelines define the optimal timing and method of repair. Meanwhile, recent advances in laparoscopic techniques are reshaping the options for the treatment of TFH. A dual approach that utilizes both laparoscopic and open methods has not previously been reported. Herein, we present the successful treatment of TFH after blunt trauma. A 46-year-old male patient underwent elective herniorrhaphy on hospital day 3, in which laparoscopic implantation of a sublay mesh and extracorporeal implantation of an onlay mesh were performed. Such techniques may be appropriate and result in feasible outcomes in hemodynamically stable patients with large TFH who are strongly suspected of having bowel herniation or concomitant intraperitoneal injuries. Larger studies are needed to assess the long-term results.

Background: Minimally invasive cardiac surgery has emerged as an alternative to conventional open surgery. This report reviews our experience with atrial septal defect using the da VinciTM surgical robot system. Materials and Methods: This retrospective study included 50 consecutive patients who underwent atrial septal defect repair using the da VinciTM surgical robot system between October 2007 and May 2011. Among these, 13 patients (26%) were approached through a totally endoscopic approach and the others by mini-thoracotomy. Nineteen patients had concomitant procedures including tricuspid annuloplasty (n=10), mitral valvuloplasty (n=9), and maze procedure (n=4). The mean follow-up duration was $16.9{\pm}10.4$ months. Results: No remnant interatrial shunt was detected by intraoperative or postoperative echocardiography. The atrial septal defects were mainly repaired by Gore-Tex patch closure (80%). There was no operative mortality or serious surgical complications. The aortic cross clamping time and cardiopulmonary bypass time were $74.1{\pm}32.2$ and $157.6{\pm}49.7$ minutes, respectively. The postoperative hospital stay was $5.5{\pm}3.3$ days. Conclusion: The atrial septal defect repair with concomitant procedures like mitral valve repair or tricuspid valve repair using the da VinciTM system is a feasible method. In addition, in selected patients, complete port access can be helpful for better cosmetic results and less musculoskeletal injury.

Background: The safety of herbal products is an important issue in Korea. It is more complicated because of the concomitant use of conventional western drugs and herbal medicine, including prescribed medicine, folk herbs and food supplements. Although both western and traditional Korean medical doctors have studied on the safety of HMP, their results did not show relevant or consistent conclusions because of the poor quality of studies, including bias. Objectives: The aim of this study was to review the studies in Korea related to drug induced liver injury (DILI) systematically. We tried to estimate the proportion of causative materials of DILI and evaluate the clinical difference of DILIs from different materials. Methods: Systematic searches were performed on MedRIC and MEDLIS in Korea. The extraction of data as well as selective screening of the studies was carried out independently by two of the authors. There were no restrictions on the types of publication, including grey literature. Results: Twenty-one articles were included. Of them only 7 adapted prospective design and only 6 were published in peer-reviewed journals. The proportion of conventional drugs associated with hepatotoxic injuries in all DILI ranged from 15.8% to 83.3% and that of herbal medicine was from 28.9% to 44.7%. However, the criteria for herbal medicine were not clearly defined and concomitant medications were not fully investigated in most studies. There were limited objective data in the clinical differences of liver injuries from different materials and their results were conflicting. Conclusions: The causality assessments regarding DILI of herbal medicine were not performed properly and causative materials were misclassified in most of the studies published in Korea. These make the safety issue still ambiguous because of the limitations and lack of objectivity of the studies. More rigorous studies are required for clearly addressing these conflicting issues with cooperative investigation between traditional Korean and western medicine.

Background Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration. Methods The medical records of 37 patients (37 orbits) with an orbital fracture with muscle incarceration from January 2001 to January 2015 were reviewed. The presence of Incarcerated muscle was confirmed via CT, as well as by intraoperative findings. Various factors potentially contributing to complications lasting for over 1 year after the injury were categorized and analyzed, including age, cause of injury, injury-to-operation time, operative time, fracture type, nausea, vomiting and other concomitant symptoms and injuries. Results All patients who presented with extraocular muscle limitations, positive CT findings, and/or a positive forced duction test underwent surgery. Of the 37 patients, 9 (24%) exhibited lasting complications, such as diplopia and gaze restriction. The mean follow-up period was 18.4 months (range, 1-108 months), while that of patients who experienced prolonged complications was 30.1 months (range, 13-36 months). Two factors were significantly associated with prolonged complications: injury-to-operation time and nausea/vomiting. Loss of vision, worsening of motility, and implant complication did not occur. Conclusions Patients who present with gaze limitations, with or without other signs of a blow-out fracture, require a thorough evaluation and emergent surgery. A better prognosis is expected with a shorter injury-to-operation time and lack of nausea and vomiting at the initial presentation.

Objective: To explore the inhibiting effect and mechanism of Endostar injection concomitant with cryoablation on lung adenocarcinoma A549 xenografts in nude mice. Materials and Methods: A total of 24 nude mice with subcutaneous xenografts of the A549 cell line were established and divided into 4 groups when the maximal diameters of tumors became 1 cm: control group, Endostar group, cryoablation group and combination group (Endostar concomitant with cryoablation). The nude mice were sacrificed after 21-days treatment, tumour tissues were removed to measure their volume, in situ test of TdT-mediated dUTP nick end labeling (TUNEL) was adopted to determine the cellular apoptosis around freezing injury zones, and immunohistochemical SP test was applied for the detection of micro-vessel density (MVD) and vascular endothelial growth factor (VEGF) expression levels. Results: At 21-days after treatment, the growth velocities of control group, Endostar group, cryoablation group and combination group were $236.7{\pm}51.2%$, $220.0{\pm}30.6%$, $159.5{\pm}29.3%$ and $103.3{\pm}25.5%$ (P<0.01), while cellular apoptosis rates of tumors were $21.7{\pm}2.34%$, ($22.17{\pm}1.47$)%, $38.3{\pm}1.37%$ and $49.2{\pm}1.72%$, (P<0.01), respectively, according to the immunohistochemical test. MVD and VEGF expression levels in the combination group were both lower than in other groups (P<0.01), also being positively related (r=0.925, P<0.01). Conclusions: Endostar can significantly improve the inhibitory effects of cryoablation on xenografts of lung adenocarcinoma A549, and the mechanism is probably associated with its function as an inhibitor of tumour neo-angiogenesis through down-regulating VEGF expression.

목적: TBI 환자의 SPECT상 혈류장애를 보이는 부위의 분포를 조사하였으며 대뇌피질과 동반된 시상의 혈류변화를 관찰하여 환자의 인지 및 행동 장애 정도를 예측 할 수 있는지 알아보고자 하였다. 대상 및 방법: TBI 후 $0.5{\sim}55$개월까지(평균 10.3개월) 뇌손상 평가를 위해 MRI영상과 Tc-99m ECD SPECT를 시행한 103명의 환자를 대상으로 하였고 남자 81명과 여자 22명이었으며, 평균연령은 $34.7{\pm}15.4$세였다. 대상환자들은 MRI영상에서 정상, 국소손상 또는 미만성 손상여부에 따라 3군으로 나누었다. 신경심리학적 검사는 정신과 의사에 의한 행동 및 성격변화의 관찰과 임상심리사에 의한 인지기능검사에 의해 총 11개의 항목이 평가되었다. SPECT에서 혈류감소를 보이는 대뇌피질의 분포를 비교하였으며 대뇌피질과 시상의 혈류감소를 같이 보인 경우와 시상의 혈류가 정상인 경우로 나누어 인지 및 행동 장애정도와 관계가 있는지 Mann-whitney의 U검정을 이용하여 유의성을 알아보았다 결과: 혈류감소를 보인 병변의 분포는 전두엽(1군 42.3%, 2군 34.5%, 3군 33.3%), 측두엽($24{\sim}26%$), 시상($21{\sim}22.4%$), 두정엽과 후두엽(10%이하)순이었다. 또한 대뇌피질과 시상의 혈류감소가 같이 있었던 경우와 시상이 정상 혈류를 보였던 경우 신경정신과적 증상을 보인 항목 수와 비교한 결과 1군에서는 전자와 후자의 경우 각각 $4.7{\pm}1.5$개와 $3.2{\pm}1.4$개였으며, 2군에서 $5.0{\pm}1.1$개와 $4.8{\pm}1.2$개, 3군에서는 $6.8{\pm}1.8$개와 $6.3{\pm}1.1$개로 MRI에서 손상의 정도가 많을수록 신경정신과적 후유증은 많았으나 SPECT에서 시상의 혈류감소 유무에 따른 증상의 심각성과 관계는 1군에서만 유의하였다(p=0.002). 결론: TBI 후 기질적 정신장애를 갖는 환자의 뇌혈류 SPECT에서 혈류감소를 보이는 병변은 주로 전두엽, 측두엽, 시상순으로 많았고 특히 전두엽은 MRI에서 정상을 보인 군에서 더욱 많은 비율을 차지하였다. MRI에서 정상일 때 SPECT에서 대뇌피질과 시상의 혈류감소가 같이 동반된 경우 시상이 정상혈류를 보인 경우보다 인지 및 행동장애의 심각성과 유의한 관계를 보였다.
