Tibial nonunion is often associated with the soft tissue atrophy and the local circulatory disturbance, so it is important to minimize the soft tissue injury and maintain the stability at fracture site for bone union. We reviewed 29 cases of subcortical onlay bone grafts and plate fixations for the nonunion and delayed union of tibial shafts, from Jan. 1988 through Jan. 1994. The results were as follows. 1. Twenty-nine patients who had nonunion of the tibia underwent subcortical cancellous onlay bone graft and plating, and 28 fractures(96.6%) went on to union. 2. Subcortical elevation or shingling of cortical bone fragments of the tibial cortex, is advocated to provide sound biological condition in atrophic soft tissue envelope. 3. Narrow DCP encouraged early motion and reliably promoted obtaining anatomical alignment. So, in treatment of protracted tibial nonunion, especially in an area with deficient soft tissue or unyielding scar tissue, subcortical onlay bone graft and plate fixation is very useful method, result in good union and no skin problem.

The authors ana lysed statistically seventy-five cases of the eye injuries in childhood under the age of 20 years old during a full year of 1972. 1. Incidence of eye injuries under 20 years old was about 1.1% of total out-patients and 39.9% of total eye injuries. 2. The most common objects to the injury were iron pieces or iron made materials (24%) such as needle, nail, flying iron piece, toy, wire and bar etc. 3. The most common nature of eye injuries was traumatic cataract (14.2%) 4. Seasonally the high peak of injuries was in summer (33.3%) and winter vacation (30.7%) 5. Blindness(under20/200 of corrected VA) was occured finally in 10.8% of total 75 cases.

Aneurysms of the superior mesenteric artery are rare, accounting for 8% of visceral artery aneurysms. About 60% of all superior mesenteric artery aneurysms have a mycotic origin. The only helpful clinical manifestations are episodes of previous abdominal pain and a history of valvular heart disease. In this case, a 66-year-old female patient with mitral regurgitation and aortic regurgitation presented with pain in the upper abdominal area. A superior mesenteric artery aneurysm was diagnosed at the time of impending rupture. Since excellent collateral circulation was present, an aneurysmectomy without revascularization was performed, and no ischemic symptom occurred. The patient presented no major complications during the postoperative course.

Objectives:
:We investigated relationship between sleep time and depression in the aged 65 years or older.
Methods:
:This study was based on the data from seventh Korean National Health and Nutrition Examination Survey (KNHANES). 3,285 people aged 65 years or older were selected as the subjects of this research. The demographic characteristics, sleep time and Patient Health Questinnaire-9 (PHQ-9) were administered for each subjects. Depression was defined as above 10 points of PHQ-9.
Results:
:All the demographic variables such as age, sex, education, household income, marital status, drinking and smoking except Body Mass Index (BMI) were correlated with the depression. When we corrected the variables, inadequate sleep time groups (less than 6 hours or more than 9 hours) tended to be depressed.
Conclusions
:The study results showed the significant correlation between sleep time and depression in the aged 65 years or older. Adequate sleep time is important to prevent the depression of the aged.

In prostate cancer patients without local invasion and metastasis, radical prostatectomy is performed as a rule for the resection of residual cancer. In a few cases, little amount of cancer volume is identified in radical prostatectomy specimens. This finding has been described as 'minimal residual cancer' or 'vanishing cancer phenomenon' and some reports have demonstrated an increase in the incidence of minimal residual prostate cancer. However, only few cases with 'minimal residual cancer' or 'no residual cancer' despite efforts searching for other possibilites have been reported. We report a case of no residual cancer in radical prostatectomy specimens of biopsy-proven prostate cancer.

BACKGROUND: The use of intravenous patient-controlled analgesia (IV-PCA) has been increasing because it has advantages such as improved pain relief, greater patient satisfaction, and fewer postoperative complications. However, current research has not considered the patients' thoughts about IV-PCA's cost-effectiveness. The purpose of this study was to investigate the willingness to pay (WTP) for IV-PCA and the relationship between patients' characteristics and WTP in Korea. METHODS: We enrolled 400 adult patients who were scheduled for elective surgery. The patient was requested to indicate a series of predefined amounts of money (Korean won; 30,000/50,000/100,000/150,000/200,000/300,000/500,000). We also recorded patient characteristics, such as age, sex, type of surgery, IV-PCA history, education level, the person responsible for medical expenses, type of insurance, net annual income, and residential area. Three days after surgery, we asked about the degree of satisfaction and the WTP for IV-PCA. RESULTS: For IV-PCA, the median WTP was 100,000 won (25-75%; 50,000-200,000 won: US$1 = W1078.04; July 19, 2011) before surgery. All patients' characteristics were not related to preoperative WTP for IV-PCA, whereas the increase in WTP after surgery showed a tendency correlated to higher IV-PCA satisfaction. CONCLUSIONS: The median WTP was 100,000 won. The satisfaction of IV-PCA increased patients' WTP after surgery, but the WTP may be independent of patient characteristics in Korea.

It is essential during extracorporeal membrane oxygenation (ECMO) to extend the activated clotting time (ACT) using anticoagulants to prevent blood clot formation. Traditionally, heparin has been used as an anticoagulant during ECMO. Hemorrhaging due to systemic heparinization is considered a major complication of ECMO. A 48-year-old man was admitted due to cardiogenic shock with acute myocardial infarction. ECMO was instituted because of recurrent ventricular tachycardia and refractory shock. We used nafamostat mesilate (Futhan) as an anticoagulant to reduce hemorrhagic complications. The total bypass time was 153 h. The average dose of nafamostat mesilate was 2.64+/-1.11 mg/kg/h; the average ACT was 128.68+/-21.24 seconds. Only a few units were transfused, and there was no oxygenator failure or hemorrhagic complications. Thus, nafamostat mesilate may reduce the need for transfusions and hemorrhagic complications during ECMO.

A 65-year-old woman was referred for management of chest pain and ST segment elevation on electrocardiography. Emergency coronary angiography revealed a well demarcated thrombus that near totally occluded the mid portion of the left anterior descending artery, with a Thrombolysis In Myocardial Infarction (TIMI) flow grade 1, and a fusiform aneurysm on the left main coronary artery. No significant stenosis was observed after aspiration of the thrombus; however, complete coronary reperfusion by urgent aspiration did not improve her dyspnea and tachypnea. Echocardiography revealed a D-shaped left ventricle; thus, we performed a chest computed tomography scan and diagnosed a pulmonary embolism. The patient's coagulation studies were normal. She was prescribed chronic anticoagulation, and we carried out transthoracic echocardiography using second harmonic imaging with agitated saline. Second harmonic imaging with the Valsalva maneuver revealed no right-to-left shunt. We report here a case of concurrent coronary embolism and pulmonary embolism without right-to-left shunt.
