A 3-year-old Thoroughbred gelding presented with left laryngeal hemiplegia with a history of laryngoplasty (tie-back surgery) failure. Postoperative endoscopy revealed no abduction or no inflammatory changes in the left arytenoid cartilage. The owner opted for the horse to undergo partial arytenoidectomy due to failed laryngoplasty. A tracheostomy tube was intubated through a mid-cervical tracheotomy to secure the airway under general anesthesia, and; laryngotomy was performed to access the arytenoid cartilage in dorsal recumbency. A partial arytenoidectomy was performed with endoscopic assistance through the left nostril, and the left arytenoid cartilage was removed, excluding the muscular process. Antibiotic and anti-inflammatory agents were administered postoperatively, and the incision site was cleaned using normal saline and antibiotic ointment twice daily. On the 12th postoperative day, endoscopy revealed redundant corniculate process mucosa at the surgical site, which was removed using rongeur forceps directly through the previous laryngotomy incision. The horse showed no significant complications during the hospitalization. Two months after surgery, the surgical site reportedly recovered with no evidence of granulation tissue. The horse returned to training and racing 3 and 7 months postoperatively, respectively. This is the first case report of a partial arytenoidectomy in a horse in South Korea. In this case, the horse returned to training after partial arytenoidectomy without significant complications, indicating that partial arytenoidectomy could be beneficial for failed laryngoplasty.

Background: Clinical outcomes after fixation of distal humerus intraarticular fractures are directly related to the quality of reduction. The use of three-dimensional (3D)-printed fracture models can benefit preoperative planning to ensure good reduction. This review aims to determine if surgery performed with 3D printing assistance are faster and result in fewer complications and improved clinical outcomes than conventional methods. We also outline the benefits and drawbacks of this novel technique in surgical management of distal humerus fractures. Methods: A systematic literature search was carried out in various electronic databases. Search results were screened based on title and abstract. Data from eligible studies were extracted into spreadsheets. Meta-analysis was performed using appropriate computer software. Results: Three randomized controlled trials with 144 cases were included in the final analysis. The 3D-printed group had significantly shorter mean operating time (mean difference, 16.25 minutes; 95% confidence interval [CI], 12.74-19.76 minutes; P<0.001) and mean intraoperative blood loss (30.40 mL; 95% CI, 10.45-60.36 mL; P=0.005) compared with the conventional group. The 3D-printed group also tended to have fewer complications and a better likelihood of good or excellent outcomes as per the Mayo elbow performance score, but this did not reach statistical significance. Conclusions: Three-dimensional-printing-assisted surgery in distal humerus fractures has several benefits in reduced operating time and lower blood loss, indirectly decreasing other complications such as infection and anemia-related issues. Future good-quality studies are required to conclusively demonstrate the benefits of 3D printing in improving clinical outcomes.

근래에 와서 심장수술 기법 및 심근보호법의 현저한 향상에도 불구하고 심장수술 환자들의 약 0.1~0.8 % 에서는 여전히 심장수술후 약물 치료나 대동맥 풍선펌프 등의 전통적인 치료법에 반응하지 않는 급성 심부전증이 발생하고 있다. 이런 환자들에서는 보다 적극적인 순환보조법으로 심실보조를 시행할 필요가 있는데, 현재 이런 목적으로 원심성 펌프가 비용이 비교적 저렴하고 사용하기 편리하다는 점에서 세계적으로 가장 많이 사용되고 있다. 그러나 아직 국내에서는 이러한 심실보조장치로서의 원심성펌프의 사용에 관한 문헌 보고가 매우 드문 실정이다. 1992년 1월 부터 1996년 1월 까지 서울대학병원에서는 총 2986례의 개심술이 시행되었는데, 이들 환자 중 모두 10명에서 심장수술후 전통적인 치료법에 반응하지 않는 심부전증이 발생하여 Biomedicus 원심성 펌프를 이용한 심실보조를 시행하였다. 10명의 환자중 남자가 8명 여자는 2명이였으며 평균 연령은 50$\pm$20세였다(범위; 9세~77세). 환자들이 받은 수술로는 6명의 환자가 관상동맥우회수술을 받았으며 이중2명의 환자는 관상동맥우회수술과 함께 대동맥판막치환수술을 시행받았다. 그밖에 대동맥박리증 수술 2례, 그리고 폐색전제거술 및 심장이식수술이 각각 1례씩 있었다. 심실보조 형태로는 전체 환자 중 5명의 환자에서 좌심실 보조를 시행하였으며 1명에서 우심실보조 그리고 4명에서 양심실보조를 시행하였다. 심실보조 기간은 평균 76$\pm$51시간이였다(범위; 24시간~175 시간). 10명중 7명에서 심실보조 장치 이탈이 가능하였고 이중4명이 생존하여 퇴원하였다. 사망 환자들의 사망 원인으로는 진행성 심부전증 2례, 그리고 다장기 부전증, 심실세동, 비가역적 뇌손상, 기계적 문제가 각각 1례씩이였다. 사망환자와 생존 퇴원환자간의 심폐바이패스시간, 대동맥차단시간, 심실보조시간에서 통계학적인 차이는 없었다. 원심성 심실보조장치 삽입에 연관된 주된 합병증으로는 출혈(7), 급성 신부전증(6), 감염(3), 그리고 신경학적 합병증(2)등이 관찰되었다. 결론적으로 원심성 펌프는 단기 순환보조용으로 비교적 만족한 결과로 사용될 수 있었다.

Purpose: As a result of dramatic advances in the medical and surgical management of congenital heart disease (CHD), many babies born with cardiac anomalies today can expect to reach adulthood. The main purpose of this study was to examine the relationship between parenting stress and personal resources of mothers of children with CHD. Method: Fifty-one mothers of children with CHD were recruited at the pediatric cardiac outpatient clinic from July 14th to September 25th 2006. Abidin's parenting stress index/short form (PSI/SF) and Brandt and Weinert's personal resource questionnaire (PRQ) were used. PSI has 3 sub-concepts; parental role distress, dysfunctional parent-child interaction, and difficult child. PRQ has 4 sub-concepts; intimacy, social integration, worth, and assistance. Data were analyzed using SPSS 13.0 version. Results: Correlation analysis showed that parenting stress was significantly related to 'intimacy', 'social integration', and 'worth' of mothers. Multiple regression analysis showed that parenting stress was significantly related to personal resource of mother and information by internet. Conclusion: Mothers who felt they had supportive friends and family, high self esteem, and social integration reported lower parenting stress. Also, internet may be an effective method to provide information and share experience for mothers of children with CHD.

A 42-year-old female was admitted with an 11-month history of progressive spastic paraparesis and ataxic gait. Magnetic resonance imaging showed intraspinal space occupying lesion compressing the spinal cord posteriorly, located from C5 to T2 with iso to high signal intensity at T2-weighted images and high signal intensity at T1-weighted images. The patient underwent surgery for decompression of the affected spinal cord because of the progressive neurological deficit. At surgery, the lesion was intradural extramedullary lipoma composed with mature adipose tissue. Partial tumor removal to decompress the neural structures and laminoplasty to avoid postoperative instability and deformity were performed. Postoperatively, she demonstrated improvement in paraparesis and was able to walk without assistance. Though attempts to decrease the size of or even to totally remove a lipoma are not required to achieve satisfactory results and carry considerable risks of surgical morbidity, a careful and limited decompression of the affected spinal cord through a partial removal of the tumor and laminoplasty could result in a significant neurological improvement.

Quality of life is the current trend and issue for the most of human diseases. In moyamoya disease (MMD), surgical revascularization has been recognized as the possible assistance to reduce the neurological insult. However, the progressive nature of the disease has been invincible so far. To improve the quality of life of MMD patients not only the protection from the neurological insult but also the maintenance or improvement of cognitive function is inevitable. For pediatric MMD patients, younger age or longer duration of disease is the key factor among the prognostic factors for bad neurological outcomes. Hence, 'the earlier, the better' is the most precious rule for treatment. Protection from neurological insult is very critical and foremost important to improve cognitive outcome. Clinicians need to know the neuropsychological profile of MMD patients for the care of whole person and make an effort to protect the patients from neurological insults to maintain or improve it.

Occasionally, unexpected neurological deficits occur after lumbar spinal surgery. We report a case of monoparesis after lumbar decompressive surgery. A 63-year-old man, who had undergone decompression of L4-5 for spinal stenosis 4 days previously in the other hospital, visted the emergency department with progressive weakness in the left leg and hypoesthesia below sensory level T7 on the right side. He had been cured of lung cancer with chemotherapy and radiation therapy 10 years previously, but detailed information of radiotherapy was not available. Whole spine magnetic resonance (MR) imaging showed fatty marrow change from T1 to T8, most likely due to previous irradiation. The T2-weighted MR image showed a high-signal T4-5 spinal cord lesion surrounded by a low signal rim, and the T1-weighted MR image showed focal high signal intensity with focal enhancement. The radiological diagnosis was vascular disorders with suspicious bleeding. Surgical removal was refused by the patient. With rehabilitation, the patient could walk independently without assistance 2 months later. Considering radiation induced change at thoracic vertebrae, vascular disorders may be induced by irradiation. If the spinal cord was previously irradiated, radiation induced vascular disorders needs to be considered.

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure. In general, a systolic blood pressure goal of <150 mm Hg and a diastolic blood pressure goal of >65 mm Hg are recommended. This article discusses the causes of increased blood pressure and the treatment methods for perioperative hypertension during the preoperative, intraoperative, and postoperative periods, in order to find ways to maintain normal blood pressure in patients during surgery. Further, in this paper, we review the causes of perioperative hypertension, such as anxiety, epinephrine, pain, and postoperative nausea and vomiting. The treatment methods for perioperative hypertension are analyzed according to the following 3 operative periods, with a review of the characteristics and interactions of each drug: preoperative antihypertensive medicine (atenolol, clonidine, and nifedipine), intraoperative intravenous (IV) hypnotics (propofol, midazolam, ketamine, and dexmedetomidine), and postoperative antiemetic medicine (metoclopramide and ondansetron). This article focuses on the knowledge necessary to safely apply local anesthesia with IV hypnotics during facelift surgery without the assistance of an anesthesiologist.

Internal hernia (IH) is a rare cause of small bowel obstruction occurs when there is protrusion of an internal organ into a retroperitoneal fossa or a foramen in the abdominal cavity. IH can be presented with acute or chronic abdominal symptom and discovered by accident in operation field. However, various kinds of imaging modalities often do not provide the assistance to diagnose IH preoperatively, but computed tomography (CT) scan has a high diagnostic accuracy. We report a case of congenital IH in a 6-year-old boy who experienced life threatening shock. CT scan showed large amount of ascites, bowel wall thickening with poor or absent enhancement of the strangulated bowel segment. Surgical exploration was performed immediately and had to undergo over two meters excision of strangulated small bowel. To prevent the delay in the diagnosis of IH, we should early use of the CT scan and take urgent operation.

Purpose: Patients with multiple trauma necessitate assistance from a wide range of departments and professions for their successful reintegration into society. Historically, the primary focus of trauma treatment in Korea has been on reducing mortality rates. This study was conducted with the objective of evaluating the current state of multidisciplinary treatment for patients with severe trauma in Korea. Based on the insights of trauma specialists (i.e., medical professionals), we aim to suggest potential improvements. Methods: An online questionnaire was conducted among 871 surgical specialists who were members of the Korean Society of Traumatology. The questionnaire covered participant demographics, current multidisciplinary practices, perceived challenges in collaboration with rehabilitation, psychiatry, and anesthesiology departments, and the perceived necessity for multidisciplinary treatment. Results: Out of the 41 hospitals with which participants were affiliated, only nine conducted multidisciplinary meetings or rounds with nonsurgical departments. The process of transferring patients to rehabilitation facilities was not widespread, and delays in these transfers were frequently observed. Financial constraints were identified by the respondents as a significant barrier to multidisciplinary collaboration. Despite these hurdles, the majority of respondents acknowledged the importance of multidisciplinary treatment, especially in relation to rehabilitation, psychiatry, and anesthesiology involvement. Conclusions: This survey showed that medical staff specializing in trauma care perceive several issues stemming from the absence of a multidisciplinary system for patient-centered care in Korea. There is a need to develop an effective multidisciplinary treatment system to facilitate the recovery of trauma patients.
