PURPOSE: We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. MATERALS AND METHODS: Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. RESULTS: In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. CONCLUSION: F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.

BACKGROUND: The cause of acrodermatitis enteropathica(AE) is closely related to zinc deficiency. Zinc is a potent inhibitor of endonuclease. Acute rises in the apoptosis in lymphoid and myeloid cell lines during zinc deficiency has recently been reported. The method of terminal transferase mediated dUTP biotin nick end labeling(TUNEL) is used in situ labelling of apoptotic nuclei in routine tissue sections. OBJECTIVE: The purpose of this study is to clarify our hypothesis that apoptosis resulted from zinc deficiency might cause keratinocytes damages in AE. METHOD: We stained 6 AE biopsy specimen with TUNEL technique. RESULTS: In acroderrratitis enteropathica, apoptotic keratinocytes were shown in the entire epidermis as compared to normal, controlled skin, in which it was found only at the uppermost layer of this stratified epithelium. CONCLUSION: This result suggests that apoptosis resulting from zinc deficiency might play a role in keratinocyte death in AE.

PURPOSE: To investigate the early results of limited open repair technique of Achilles tendon ruptures, and to describe the surgical technique. MATERIALS AND METHODS: From October 2004 to February 2005, a total of 10 patients with Achilles tendon rupture underwent limited open repair. The average age of the patients was 39.3 years, and the average follow-up period was 9 months. The causes of injury were sports injuries in 8 cases, and slip down in 2. The mean interval between the injury and the operation was 9 days. The clinical results were assessed by patient's satisfaction, incision length, hospitalization, the ankle-hindfoot scale of American Foot and Ankle Society (AOFAS), and complications. RESULTS: Of 10 patients, 8 were very satisfied, and the remaining 2 were satisfied. The mean incision length was 2.0 cm, and the mean hospitalization was 2 days. The mean AOFAS score was 97 points, and there was no complications such as infection, rerupture, or nerve injury. All patients returned to work at approximately 2 months, and resumed light exercise such as jogging at approximately 3 months. CONCLUSION: Limited open repair technique of Achilles tendon ruptures is provided for better cosmetic results, high patient's satisfaction, and functionally successful results without postoperative complications.

BACKGROUND: Living related liver transplantation (LRLT) was developed to alleviate the mortality resulting from the scarcity of suitable cadevaric grafts. The purpose of this study is to review 30 cases of pediatric living-related liver transplantation, and to find the proper anesthetic management for this operation. METHODS: We retrospectively analyzed the medical records of 23 cases (body weight < 15 kg) of liver transplantation from living related donors between August 1995 and May 1998. RESULTS: Mean age and body weight were 14 (range; 6-29) months, 8.7 (range: 5.4-12.2) kg, respectively. The most common cause of end stage liver disease was biliary atresia. After reperfusion there were significant decreases of mean arterial pressure and body temperature, and increases of central venous pressure (P< 0.05), whereas the change of heart rate was not significant. The incidence of postreperfusion syndrome was 26%. Serum Na levels increased significantly (P< 0.05) from 133 3 to 144+/-3 mEq/L, and K level decreased from 4.1+/-0.7 to 3.2+/-0.5 mEq/L during surgery. Hematocrit was 26+/-3.5%, platelet 10.3+/-7.2 x 104/mm3 at the time of peritoneal closure. Wide inter-individual RBC and FFP requirements were observed, 43+/-40 (range: 5-133) mL/kg, 108+/-82 (range: 22-300) mL/kg, respectively. CONCLUSIONS: We conclude that anesthetic management for pediatric LRLT and LRLT in recipients less than 15 kg in body weight can be carrid out, through with some precautions.

PURPOSE: To report a case of isolated choroidal cystic lesion in the macula with no interval change for two years. CASE SUMMARY: A 29-year-old woman who had suspicious maculopathy was referred to our clinic. Her best corrected visual acuity was 20/20 in the affected right eye, which showed a choroidal cystic lesion on a fundus exam, fluorescein angiography, USG and OCT. The multifocal ERG showed reduced amplitudes of the cystic area in the right eye, and SLO microperimetry revealed reduced retinal sensitivity in the cystic lesion as well as a stable fixation and spared foveal function. There was no evidence of underlying ocular disease in clinical assessment, and the lesion had not undergone interval change for the past two years.

An abnormal dipping pattern in ambulatory blood pressure monitoring (ABPM) is a cardiovascular (CV) risk factor. However, its impact on CV mortality has not been investigated sufficiently in clinical practice to be considered a standard parameter. We assessed the association between abnormal dipping patterns and increased CV mortality in a tertiary hospital in Korea. Our retrospective cohort study included 401 patients who underwent ABPM between 1994 and 1996 in Hanyang University Hospital, Seoul, Korea. The patients were classified as risers (<0% drop in systolic BP; n=107), and others included dippers and non-dippers (> or =0% drop, n=294). The follow-up period was 120 months. The frequency of CV mortality was 14.0% in risers and 5.8% in others. A Cox regression analysis found a significant association between dipping pattern and CV mortality, after adjusting for age, gender, body mass index, hypertension, diabetes mellitus, smoking and hypercholesterolemia. Risers were at greater risk of CV death than others (RR, 3.02, P=0.022), but there was no difference in event rates between dippers and non-dippers. The reverse dipping pattern may be more frequent in clinical settings than in the population at large, and it is strongly associated with increased risk of CV mortality in Korea.

Adrenal cysts are rare lesion that usually present themselves as an incidental finding during surgery, or at the time of autopsy. The cysts are usually small, seldom exceeding 10cm in diameter, and are generally asymptomatic. However, they present a difficult problem in differentiation between benign and malignant lesions of the adrenal gland. In the differential diagnosis, other cystic lesions of the upper abdomen must also be considered, including hepatic, splenic, renal and pancreatic cysts. Herein we report a case of endothelial cyst of lymphangiomatous type of the adrenal gland which was detected in a 44-year-old male patient during a routine health examination by ultrasonography as a pancreatic pseudocyst. Gross examination revealed multiple separate but continuous cysts, measuring 10.6x8x7cm in dimension. Within the wall, compressed adrenal cortex was noted. Microscopically, fibrous wall containing hypertrophied smooth muscle lined by endothelial cells was also noted. We reviewed literatures of the adrenal cyst and report a case.

BACKGROUND: Smoking is the most important and consistent determinant of the development and progression of COPD(Ed Note : Define COPD). The fact that cigarette smokers develop a different type of COPD, chronic bronchitis and emphysema, with different clinical and pathological aspects, suggests that the development of COPD has a relationship with other smoking-associated factors beyoud just a simple smoking history. The aim of this was to analyze the smoking habits and history of patients with COPD and to evaluate the development of different types of COPD accordint to patient's smoking habits. METHOD: To evaluate the differences in the smoking patterens of patients with chronic bronchitis and emphysema, a pulmonary function test was conducted, and the smoking history and patterns was obtained through a smoking history questionnaire by a direct personal interview from 333 male cigarette smokers diagnosed with COPD, in the Yeungnam university medical center(190 patients diagnosed with chronic bronchitis, 143 patients diagnosed with emphysema). RESULT: The patients with emphysema smoked earlier and had a higher smoking history(ie, more pachyears, more total amounts of smoked cigarette, and more deep inhalation and longer duration of plain cigarette exposure) than those with chronic bronchitis. The depth of ingalation was also significantly higher in the emphysema patients after taking into account age, cumulative cagarette consumption and the type of cigarette smoked. CONCLUSION: Emphysema was more associated with the increasing degree of inhalation as assessed by the depth of inhalation. A high alveolar smoke exposure may be a significant risk factor for the development of emphysema.
