본 연구에서는 난소자궁적출술에 있어서 티타늄(titanium) 클립 적용 시 발생할 수 있는 합병증을 평가하고, 난소혈관과 난소걸이인대의 두 가지 결찰법을 비교하여 합병증을 최소화 할 수 있는 수술법을 찾고자 하였다. 실험을 위해 6마리의 암컷 비글견이 사용되었으며, 세 마리씩 두 그룹으로 나누어 한 그룹은 난소걸이인대와 난소혈관을 함께 결찰 하였고, 나머지 한 그룹은 난소걸이인대를 결찰하지 않고 난소혈관만 결찰 하였다. 두 수술법을 비교하기 위해서 매달 1회씩 1년 동안 복강 X-ray 검사를 통해 적용된 클립의 위치 변화를 확인하였고, 적용된 클립에 의한 염증반응 유무는 혈액검사를 통해 확인하였다. X-ray 검사 상에서 두 그룹의 클립 위치는 큰 변화를 보이지 않았으며, 혈액 검사에서도 거의 모든 수치들이 정상범위에 있었고, 염증과 관련된 임상증상 또한 관찰되지 않았다. 부검을 통한 두 그룹의 클립 포매 형태를 관찰한 결과 난소걸이인대를 결찰한 클립은 복강의 얇은 막으로 두껍게 싸여서 신장 후연에 위치하고 있는 것을 확인하였고, 난소걸이인대를 결찰하지 않은 클립은 얇게 둘러싸인 막 표면에 위치하여 신장의 아래쪽에서 관찰되었다. 이러한 결과는 난소걸이인대가 클립의 움직임을 최소화 할 수 있도록 지지해주는 역할을 하는 것을 의미하며, 따라서 티타늄 클립을 적용하는 난소자궁적출술에서 난소걸이인대를 함께 결찰하는 방법이 합병증 예방에 있어서 보다 적합한 방법으로 생각된다.

The superior shoulder suspensory complex is composed of glenoid fossa, coracoid process, coracoclavicular ligament, distal clavicle, acromioclavicular ligament, acromion. Traumatic double disruptions of this complex lose its suspensory action on the shoulder joint and result in functional loss and deformity. Careful radiologic evaluation and appropriate management are required for injuries to this complex. Ipsilateral fractures of clavicle and scapula create unstable anatomic situation on shoulder joint. Conservative treatment usually fails to achieve good functional recovery due to rotator cuff weakness, nonunion, delayed union, malunion and neurovascular injury. Authors studied the result of operative treatment of ipsilateral clavicle and scapular fractures to prevent such complications. Seven cases were treated with open reduction and internal fixations of clavicle alone or clavicle and scapula simultaneously and followed up for nineteen months(twelve months - thirty-eight months). All but one patient showed good or excellent functional result according to the scoring system of Rowe. Poor result was developed in the case which had brain injury. Rigid fixations of clavicle alone or clavicle and scapular fractures both can achieve stable reduction of the fractures and prevent sequelae. We concluded that operative treatment of ipsilateral fractures of clavicle and scapula is safe and yields predictable good results.

겸상인대는 원인대 및 배꼽정맥의 잔유물을 포함하는 구조물로서 배꼽에서 횡격막까지 이어지는 간의 걸이인대이다. 겸상인대에서 발견되는 인대 낭종, 종양, 비정상적인 혈관, 선천적 인대결손 같은 드물게 나타나는 병인 중에서도, 겸상인대 농양은 굉장히 드문 질환이다. 따라서 겸상인대 농양에 대한 정확한 진단은 어려우며, 총담관낭의 감염이나 간농양으로 잘못 해석하기 쉽다. 저자들은 생후 25일된 신생아에게서 배꼽 정맥 도관 삽입 후 발생한 겸상인대 농양에 경피적 배액 및 항생제 투여를 통해 성공적으로 치료된 증례를 보고하고자 한다.

Purpose: Tunnel widening following anterior cruciate ligament (ACL) reconstruction is commonly observed. Graft micromotion is an important contributing factor. Unlike fixed-loop devices that require a turning space, adjustable-loop devices fit the graft snugly in the tunnel. The purpose of this study is to compare tunnel widening between these devices. Our hypothesis is that the adjustable-loop device will create lesser tunnel widening. Materials and Methods: Ninety-eight patients underwent ACL reconstruction from January 2013 to December 2014. An adjustable-loop device was used in 54 patients (group 1) and a fixed-loop device was used in 44 patients (group 2). Maximum tunnel widening at 1 year was measured by the L'Insalata's method. Functional outcome was measured at 2-year follow-up. Results: The mean widening was 4.37 mm (standard deviation [SD], 2.01) in group 1 and 4.09 mm (SD, 1.98) in group 2 (p=0.511). The average International Knee Documentation Committee score was 78.40 (SD, 9.99) in group 1 and 77.11 (SD, 12.31) in group 2 (p=0.563). The average Tegner-Lysholm score was 87.25 (SD, 3.97) in group 1 and 87.29 in group 2 (SD, 4.36) (p=0.987). There was no significant difference in tunnel widening and functional outcome between the groups. Conclusions: The adjustable-loop device did not decrease the amount of tunnel widening when compared to the fixed-loop device. There was no significant difference in outcome between the two fixation devices. Level of Evidence: Level 3, Retrospective Cohort.

In this report, laparoscopic ovariohysterectomy (LOHE) was performed on two, healthy, intact female dogs. Three ports, umbilical port for placing the laparoscope and the left and right paramedian instrument ports were placed into the abdominal cavity. First, in order to isolate the right ovary, the vascular pedicle was coagulated by activating the universal bipolar forceps. Then, the pedicle and suspensory ligament were transected by the bipolar electrocauterization scissors. In the same manner, the left ovary was isolated. The uterine body and the uterine arteries were coagulated bilaterally and transected just rostral to the cervix. The isolated ovaries and uterus were exteriorized through the left paramedian instrument port, which was extended by approximately 1 cm to allow for tissue removal. The skin and subcutaneous tissue were closed in a routine manner. Surgical times for LOHE in two dogs were 35, 40 min respectively. Total length of abdominal incision was shorter than 3 cm in two dogs. No clinical complications related to the LOHE were observed during 1.5 years after surgery. The LOHE is an alternative surgical technique that deserves further investigation.

Objective: This study was conducted to estimate multi-trait genetic parameters for somatic cell score (SCS), milk yield and type traits in Nigerian Dwarf (ND) goats from the United States. Methods: Data from 1,041 ND goats in the United States with kiddings in 95 herds were used to estimate multi-trait genetic parameters for SCS, milk (MILK), fat (FAT), and protein (PROT) yields, and 14 type traits. An 18-trait mixed linear animal model for lactation mean SCS (Log₂), MILK, FAT, PROT, and 14 type traits was applied. A factor analytic approach (FA1) in ASReml software was used to obtain convergence. Results: Averages for SCS were low (2.85±1.29 Log₂), and were 314±110.6, 20.9±7.4, and 14±4.9 kg, respectively, for MILK, FAT, and PROT. Heritabilities for SCS, MILK, FAT, and PROT were 0.32, 0.16, 0.16, and 0.10, respectively. The highest heritabilities for type traits were for stature (0.72), teat diameter (0.49), and rump width (0.48), and the lowest estimates were for dairyness (0.003) and medial suspensory ligament (0.03). Genetic correlations of SCS with MILK, FAT, and PROT were positive but low (0.25, 0.18, and 0.23, respectively). Genetic and phenotypic correlations between MILK, FAT, and PROT were high and positive (≥0.66). Absolute values of genetic correlations involving SCS with type traits were generally low or no different from zero. Most of the phenotypic correlations involving SCS with type traits were low. No serious unfavorable genetic correlations between milk yield traits and SCS or between milk yield traits or SCS and type traits were found. Conclusion: Genetic variation exists in the ND breed for most studied traits. The development of selection programs based on these estimates may help accelerate favorable multi-trait genetic changes in this breed.

자궁축농증으로 내원한 고양이에서 복강경을 이용한 난소자궁절제술을 시행하였다. 먼저 제대 port를 통해 5 mm working channel을 가진 10 mm 복강경을 복강내로 삽입하였다. Working channel을 통해 복강 내로 도입된 atraumatic grasping forceps을 이용하여 난소를 배측복벽으로 견인한 후 난소 동,정맥을 노출시키기 위해 난소를 배측 복벽에 일시적으로 고정시키는 transabdominal suspension suture를 적용하였다. 난소 동, 정맥과 난소걸이인대는 5 mm multifunction bipolar grasping forceps을 이용하여 순차적으로 소락절제하였다. 양쪽 난소의 절제 후, 제대 port의 꼬리쪽 방향에 5 mm 직경의 추가 port를 장착하였다. 추가 port를 통해 grasping forceps을 복강 내로 삽입한 후 절제된 난소와 자궁을 복강 밖으로 배출하였다. 이때 자궁의 배출이 용이하도록 port의 직경을 2 cm로 확장하였다. 자궁몸체와 자궁동맥은 복강 밖에서 결찰 후 절제하였다. 술 후 5주간의 관찰 결과, 복강경수술과 관련된 어떠한 부작용도 관찰되지 않았다. 본 증례는 고양이에서 자궁축농증 치료에 복강경을 적용한 예이다.
