Objectives : The purpose of this study is to report one case of Korean medical treatment of patient with developmental abnormality by cerebral palsy whose main symptoms are difference in left and right leg length, foot size and construction of right ankle. Methods : We did retrospective study for one developmental abnormality patient who had been treated by herbal medicine(Samul-tang, Yookmijihwang-tang hap Yijin-tang + Sungjang-hwan), acupuncture, and moxibustion for more than one year. The effects of treatment were evaluated by measurement of leg length, foot size and dorsiflexion ROM. Results : After treatment, length and foot size difference between both leg, ROM difference between both ankle were almost reduced. According to the ratio of the right to the left, leg length was improved from 0.91 to 0.98 and foot size was improved from 0.93 to 0.98. The difference in left and right ankle dorsiflexion ROM was improved from 55° to 27.5°. Conclusions : This clinical case study has demonstrated that Korean medicine may be an safe and effective option for treating developmental abnormality.

Background and Objectives: Pathophysiological changes of right ventricle (RV) after repair of tetralogy of Fallot (TOF) are coupled with a highly compliant low-pressure pulmonary artery (PA) system. This study aimed to determine whether pulmonary vascular function was associated with RV parameters and exercise capacity, and its impact on RV remodeling after pulmonary valve replacement. Methods: In a total of 48 patients over 18 years of age with repaired TOF, pulmonary arterial elastance (Ea), RV volume data, and RV-PA coupling ratio were calculated and analyzed in relation to exercise capacity. Results: Patients with a low Ea showed a more severe pulmonary regurgitation volume index, greater RV end-diastolic volume index, and greater effective RV stroke volume (p=0.039, p=0.013, and p=0.011, respectively). Patients with a high Ea had lower exercise capacity than those with a low Ea (peak oxygen consumption [peak VO₂] rate: 25.8±7.7 vs. 34.3±5.5 mL/kg/min, respectively, p=0.003), while peak VO₂ was inversely correlated with Ea and mean PA pressure (p=0.004 and p=0.004, respectively). In the univariate analysis, a higher preoperative RV end-diastolic volume index and RV end-systolic volume index, left ventricular end-systolic volume index, and higher RV-PA coupling ratio were risk factors for suboptimal outcomes. Preoperative RV volume and RV-PA coupling ratio reflecting the adaptive PA system response are important factors in optimal postoperative results. Conclusions: We found that PA vascular dysfunction, presenting as elevated Ea in TOF, may contribute to exercise intolerance. However, Ea was inversely correlated with pulmonary regurgitation (PR) severity, which may prevent PR, RV dilatation, and left ventricular dilatation in the absence of significant pulmonary stenosis.

배경: 관상동맥우회술 시 내유동맥편의 골격화 채취법의 이론적인 장점들의 하나는 골격화 채취가 내유동맥의 채취에 필연적으로 수반되는 흉골로의 혈류 공급의 감소를 최소화시킨다는 것이다. 저자들은 술 전과 술 후 각각 골주사를 통하여 좌측 및 우측 흉골로의 흡수율을 비교 분석하여, 술 후 내유동맥편의 채취 방법에 따른 흉골로의 혈류 감소의 차이를 증명하고자 하였다. 대상 및 방법: 2002년 4월부터 2003년 3월까지 시행한 48예의 관상동맥우회술 환자들 중 술 전 및 술 후 1일째 골주사를 시행한 27예의 환자를 대상으로 하였다. 8예의 환자에서 양측 내유동맥을 모두 사용하였으며(BIMA군), 19예의 환자에서 좌내유동맥만을 사용하였는데(LIMA군), 이 중 골격화 채취를 하여 사용한 환자가 12예(LIMA_skel군), 경상 채취하여 사용한 환자가 7예(LIMA_ped군)였다. 골주사를 시행 후 임의의 정중선을 기준으로 흉골의 좌측 부분에 관심 영역을 그리고 흉골의 반대편에 이 영역의 대칭영상을 만들어 또 하나의 관심 영역을 만든 후 각 관심 영역의 화소 당 평균 계산치를 택하여 좌우비를 산출 하였다. 결과: LIMA군에서 좌우비는 수술 전 94.6$\pm$4.1%에서 술 후 87.9$\pm$6.9%로 감소한 반면(p=0.003), BIMA군에서는 통계적으로 유의한 변화를 보이지 않아 좋은 대조를 보였다. LIMA_skel군 과 LIMA_ped군에서의 좌우비는 각각 수술 전 95.3$\pm$4.2% 및 93.4$\pm$3.9% 에서 술 후 88.3$\pm$7.7% 및 87.4$\pm$5.8%로 감소하였으나 감소 정도를 분율로 표시하였을 때 LIMA_skel군이 -7.44$\pm$7.08, LIMA-ped 군이 -6.17$\pm$9.08로 통계적인 유의성은 없었다. 결론: 술 후 흉골의 골주사 흡수의 감소는 내유동맥의 채취가 채취방법에 상관없이 동측의 흉골의 혈류 공급을 감소시킴을 시사하였다. 내유동맥의 골격화 채취가 비골격화 채취에 비하여 흉골의 혈류 공급의 보존 측면에서 월등한 이점을 보이지는 않았다.

A 5-year retrospective study of 14 patients with diaphragmatic injuries revealed 9 blunt and 5 penetrating injuries. In the blunt trauma group, 7 were left and 2 were right side. The penetrating diaphragmatic wound consist of 3 left and 2 right sided. Sex ratio was 11: 3, with male predominanace. Preoperative diagnosis was possible in 9 cases and delayed diagnosis [greater than 24 hours occured in 5 cases.Simple chest X-ray was diagnostic or highly suggestive in 7 cases. 7 cases were diagnosed diaphragmatic injuries by computed tomography, fiuroscopy or by explorative operation. All of the cases had association injury. 11 cases of diaphragmatic ruptures were corrected through thoracotomy and 3 cases needed exploratory laparotomy. One death occured after operation due to associated injuries and respiratory failure. Blunt and penetrating diaphragmatic injuries remain a diagnostic challenge and associated injuries, delayed diagnosis determine the outcome.

Purpose: The purpose of this study was to report the treatment results of patients with traumatic cardiac tamponade after the opening of Jeju Regional Trauma Center. Methods: We analyzed the treatment outcomes of patients with traumatic cardiac tamponade who were treated at Jeju Regional Trauma Center from January 2018 to August 2022. Results: Seven patients with traumatic cardiac tamponade were treated. The male to female ratio was 1.33:1 (four male and three female patients) and the average age was 60.3±7.2 years. The mechanism of injury was blunt trauma in six cases and penetrating injury in one case. Upon arrival at the emergency department, pericardiostomy was performed in four cases, and an emergency operation was performed in six cases. Pericardiostomy alone was performed in one patient, who had cardiac tamponade due to extrapericardial suprahepatic inferior vena cava rupture. The causes of cardiac tamponade were right atrium appendage rupture in one case, right ventricle rupture in one case, inferior vena cava rupture in two cases, right atrium and left atrium rupture in one case, both atria and left ventricle rupture in one case, and intercostal artery rupture in one case. In three cases, intraoperative cardiopulmonary bypass was required. Two of the seven patients died (mortality rate, 28.5%). Conclusions: Relatively favorable treatment results were observed for traumatic cardiac tamponade patients after Jeju Regional Trauma Center was established.

Objectives The second to fourth digit ratio (2D : 4D) is known to reflect testosterone level during intrauterine period. Testosterone is essential for masculinization of brain. Cloninger's type II alcoholism is characterized by early age at onset and largely limited to males. Compared with type I alcoholism, type II alcoholism is thought to be masculine. There is a possibility that the digit ratio of type II alcoholism is low compared with type I. We examined digit length ratio in Cloninger's type I and II alcoholism to understand the effects of intrauterine testosterone on the development of alcoholism. Methods The participants were 87 alcohol dependent patients. We divided two subtypes of patients by Irwin's symptom list, based on Cloninger's concept. We captured the images of both palms by the scanner and measured the lengths of digits by the graphic program. Then we analyzed the digit ratios by independent-sample t-test. Results The mean 2D : 4D of type I was 0.942 (right), 0.952 (left). The mean 2D : 4D of type II was 0.927 (right), 0.940 (left). In both hands, 2D : 4D of type II was significantly lower than type I. Conclusions Type II alcoholism showed masculine type of digit length ratio compared with type I. It suggests the exposure of testosterone during intrauterine period might play an important role in determining the course and feature of alcoholism.

This study was performed to compare the radiographic and echocardiographic features of cardiovascular changes between small and large dogs with heartworm diseases. Total of 49 dogs from two institutions were included in this study. The dogs were diagnosed with heartworm infestation and underwent thoracic and echocardiography. On thoracic radiographs, vertebral heart scale, reverse D shape, main pulmonary artery dilation, peripheral pulmonary artery dilation, and evidence of right heart failure were evaluated. On echocardiographs, visibility of worms, main pulmonary artery to aortic root (MPA/Ao) ratio, right to left ventricular basal diameter (RVD/LVD) ratio, and pulmonary hypertension were evaluated and analyzed between small and large dogs. The proportion of reverse D shape of the heart and accuracy for right ventricular hypertrophy in small dogs were lower than those of the large dogs. For echocardiographic parameter, the MPA/Ao and RVD/LVD ratio in the small dogs were significantly lower than those of the large dogs. As the results, thoracic radiography have a tendency to underestimate the severity of HWD in small dogs and should be used with echocardiography.

The Fontan procedure was physiological correction which was initially applied to tricuspid atresia. We had used the modified Fontan operation in 8 cases at National Medical Center, Seoul, from Aug. 1984 to Oct. 1986. Age range was 20 months to 15 years [mean: 9 years] and male: female ratio was 5:3. 5 patients had tricuspid atresia [lb: 2 cases, Ic: 1 case, lib: 1 case, & llc: 1 case], 2 Patients had univentricular heart of left ventricular type, and one patient had transposition of great arteries with complete endocardial cushion defect. The operative principle was direct anastomosis between right atrium and pulmonary artery, whether main pulmonary artery or right pulmonary artery without any conduits. Postoperatively all patients needed high central venous pressure for adequate hemodynamic status in both survival [20-24 CmH2O] and mortality groups [20-24 CmH2O]. The fatal complications were as follows: empyema with bronchopleural fistula [1 case], bleeding tendency & brain damage [1 case], low cardiac output syndrome & acute renal failure [2 cases], and right to left shunt of unknown origin [1 case]. There were 5 hospital deaths; 3 of 5 tricuspid atresia patients, 1 of 2 univentricular heart patients, and 1 of 1 transposition of great arteries with complete endocar4ial cushion defect patient. The overall mortality was 62.5%. 3 survivors were nearly compatible with Choussat & Fontan criteria. Thus appropriate patient selection and experienced surgical technique were required for good results.

To evaluate the diagnostic usefulness and significance of quantitative sacroiliac joint scintigraphy in the assessment of sacroiliitis, we measured Sacroiliac Joint/Sacrum Uptake Ratio(SIS Ratio) by region of interest(ROI) method using $^{99m}Tc-methylene$ diphosphonate. The observed results were as follows: 1. Using ROI method, the SIS ratios for the control group of 65 persons were $1.05{\pm}0.08$(left) and $1.06{\pm}0.07$(right) which were narrower in range than those of slice method $(mean{\pm}S.D.)$. 2. The effects of age, gender and laterality on SIS ratio were not significant. 3. In left side, one of 6 patients with rheumatoid arthritis had SIS ratio in excess of 2 standard deviation of normal control group, and remainder had SIS ratios within normal limit. In right side, 3 patients had SIS ratios in excess of 2 standard deviation of normal control group, and remainder, within normal limit. 4. In both sacroiliac joint, 2 of 3 patients having sacroiliitis clinically with Reiter's syndrome whose pelvis A-P X-ray findings showed normal had high SIS ratios (left/right; 1.31/1.69, 1.90/1.80), but SIS ratio of one patient who had no evidence of sacroiliitis clinically was within normal limit. 5. In 6 patients with ankylosing spondylitis in both sacroiliac joints, 4 whose pelvis A-P Xray findings showed severe sclerotic change of sacroiliac joints had SIS ratio within normal limit or below that of normal control group, and SIS ratios of 2 patients whose pelvis A-P X-ray findings showed were increased. 6. 4 of 5 patients with low back pain of which cause could not be evaluated clinically and radiologically had SIS ratios in excess of that of normal control group. It would be concluded that quantitative sacroiliac joint scintigraphy is useful and sensitive screening method in the diagnosis as well as in the assessment clinical activity of sacroiliitis.

Clinical analysis were performed on 247 cases of thoracic trauma, those were admitted & treated at the department of thoracic & cardiovascular surgery,Hanyang University Hospital during the period from Jan,1989 to June,1992. Age distribution of those was from 2 to 80 years old & mean age was 38 years old. The ratio of male to female patient was 186:61 [3:1].This ratio revealed high incidence in male patient. The most common cause of trauma was traffic accident in this series.The modes of injury were as follows: traffic accident 124 cases[50.2%],fall down 52 cases[21.05%], stab wound 47 cases[19.03%] and gun-shut wound 1 case.Ellapse time from accident to admission were 141 cases [57.09%] under 6 hr.Rib fracture were observed in 159 cases[64.37%], hemo or pneumothorax were observed 134 cases[54.25%] of total cases and location distributed Right:Left:Both[74:112:37], in left predominant. Conservative,non-operative treatment were performed in 128 cases and operation[open thoracotomy] 32 cases.Mortality was 1.6%[4 cases] & most common cause of death were due to irreversible shock with brain edema. Conclusively, more evaluation & co-operation of other department were expected treatment & better prognosis.
