BACKGROUND/AIMS: Experimental studies using porcine non- heart beating donors to ameliorate graft injuries in liver transplantation has been conducted. Recently, it has been reported that cellular calcium may have an important role in ischemic injury, which consists of damage during ischemia and impairment at the time of reperfusion. therefore, it is possible that calcium channel blocker might prevent warm ischemic injury of the graft in liver transplantation when administered to the donor before harvesting and to the recipient at reperfusion. the purpose of this study was to investigate the protective effect of a calcium channel blocker diltiazem (DTZ) on hepatic ischemic injury using a porcine model. METHODS: Twenty pigs weighing 20 to 30 kg were enrolled in this study. Cardiac death was induced by direct cardiac injection of potassium chloride. The perfusion of UW (University of Wisconsin) solution started after 30 min of cardiac arrest. Orthotopic liver transplantation was perforated. Group A (experimental group) was administrated of DTZ at a dose of 70microgram/kg bolus iv injection before hepatic ischemia, perfused of 70microgram/L in UW solution and thereafter infused continuously 70microgram/L in 5% dextrose solution. RESULTS: Two ones death occurred among the ten transplant pigs. 24 hour survival rates were 80%. DTZ administrated group showed the hepatic blood flow and arterial ketone body ratio better compared with untreated controls (p<0.05). In addition, the increase of plasma lactate level was suppressed after ischemia (p<0.05). CONCLUSION: Our results suggest that DTZ has a protective effect on ischemic induced hepatic damage and might be useful in the prevention of primary graft failure caused by warm ischemia in liver transplantation.

Interstitial ectopic pregnancy is a rare condition of pregnancy and may be very dangerous if not identified and treated urgently. We report a case of successful treatment of an interstitial pregnancy using selective uterine artery embolization. A 27-year-old woman with interstitial pregnancy was treated by uterine artery embolization after failure of systemic methotrexate treatment. Her serum beta-human chorionic gonadotropin (β-hCG) was undetectable one month after the therapeutic embolization and transvaginal sonography 31 days after embolization showed normal endometrium and cornu. The patient achieved a normal pregnancy eight months after embolization.

PURPOSE: Periods of L-T4 withdrawal and low iodine diet, which are required prior to the treatment and tracking tests that take place after a thyroidectomy, can be of a long duration and cause suffering for patients. The purpose of this study, conducted in South Korea, was to confirm if periods of L-T4 withdrawal and low iodine diet can be shortened by using TSH level prediction. By inquiring into the correlation between TSH level and serum Tg level, and measurement of the amount of iodine present in urine during the low iodine diet period, a thyroglobulin (Tg) cutoff level can be predicted. METHODS: total of 168 patients were included as research subjects. In each case, L-T4 was suspended 3-4 weeks prior to conducting radioactive iodine ablation and 131I scan, and then a low iodine diet was carried out for 2-4 weeks. Serum TSH, Tg and anti-Tg antibodies were measured on the second week of L-T4 withdrawal, and the spot urine Iodine/Creatinine ratio was measured on the second and fourth week after treatment. RESULTS: Three weeks after L-T4 withdrawal, TSH levels increased to over 30μIU/ml in 97.2% of the patients, and serum thyroglobulin levels also increased with TSH level to over 30μIU/ml. There was no measured difference in the amount of iodine in the subject's urine during the low iodine diet period. CONCLUSION: It was found that L-T4 withdrawal can be reduced to 3 weeks or less, and that the Tg cutoff level differs according to TSH level. Based on these results, we suggested that the low iodine diet period can be reduced to 1-2 weeks.

Tuberculosis is a multi-organ disease. The incidence of pulmonary tuberculosis is declining due to improvement in public health, vaccination and the development of anti-tuberculosis medication, but extrapulmonary tuberculosis has become more common, especially in immuno-compromised individuals, AIDS patients and immigrants to western worlds. Gastrointestinal tuberculosis continues to give rise to diagnostic and therapeutic challenges. The jejunal tuberculosis is uncommon and presents a difficult diagnostic problem. Bleeding jejunal tuberculosis is a very rare source of lower gastrointestinal bleeding. We have recently experienced a case of a jejunal tuberculosis which was proven to be a source of gastrointestinal bleeding by intraoperative endoscopy and was confirmed by surgical exploration. This report summarized our experience and review of literature.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.

BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.
