BACKGROUND: Efficacy of percutaneous transluminal angioplasty(PTA) in the treatment of Peripheral arterial disease has been established. Complications such ans PTA-induced dissections or residual stenosis with occasional mural thrombi have been reported, which compromise the results. New procedures can be used in combination with PTA to improve the immediate and long term results, such ans prolonged balloon inflation, atherectomy, or implantation of endovascular prosthesis. In addition, the occurrence of other lesions, such as spontaneous or post-catheterization dissection or post-PTA restenosis, has prompted the insertion of a vascular stent. But there was few reports on stenting for peripheral arterial disease in Korea. METHODS: To evaluate the safety, efficacy and stability of stent in peripheral arterial disease, twenty-six consecutive symptomatic patients with 37 peripheral lesions were treated with 39 balloon expandable(33 Strecker and 6 Palmaz)stents with or without prior balloon angioplasty in the period of March 1991 and February 1994. RESULTS: The major cause of disease was arteriosclerosis(22 out of 26). The implantation sites for our study include 22 in common iliac artery, 11 in external iliac artery 2 in aorta, subclavian artery, superficial femoral artery each other. Indication for stent deployment were primarily suboptimal results(19 lesions), insufficient PTA such as dissections(4), restenosis after previous PTA(2), and primary stenting was performed without preceding therapeutic PTA(10). Stent deployment was technically successful in 24 of the 26 patients(92%) and clinical success rate was in 25 of the 26 patients treated(96%). Hemodynamic change revealed markedly improvement before and after stenting(peak pressure difference from 66.329.0mmHg to 9.1+/-7.1mmHg; Mean pressure difference from 33.0+/-22.5mmHg to 4.7+/-4.3mmHg). There were two procedural complications which included one stent migration and one artery perforation. During the 7 months of follow-up(1-18 momths), two restenosis occurred. One patient died due to cerebral hemorrhage during thrombolysis with urokinase. CONCLUSION: The stent deployment is relatively safe and very effective primary therapeutic modality and may abolish the limitation of PTA such as suboptimal result, dissection with sudden occlusion and restenosis in peripheral vascular disease and highly recommended in selected cases.

PURPOSE: Radiotracers that bind to the central benzodiazepine receptor are useful for the investigation of various neurological and psychiatric diseases. [C-11]Flumazenil, a benzodiazepine antagonist, is the most widely used radioligand for central benzodiazepine receptor imaging by PET. We synthesized 3-(2-[F- 18]fluoro)flumazenil, a new fluorine-18 (t1/2=110 min) labeled analogue of benzodiazepine receptor imaging agent, and evaluated in vivo for biodistribution in mice. MATERIALS AND METHODS: Flumazenil (Ro 15-1788) was synthesized by a modification of the reported method. Precursor of 3-(2-[F-18]fluoro)flumazenil, the tosylated flumazenil derivative was prepared by the tosylation of the ethyl ester by ditosylethane. [F-18] labeling of tosyl substitued flumazenil precursor was performed by adding F-18 ion at 85 degree C in the hot cell for 20 min. The reaction mixture was trapped by C18 cartridge, washed with 10% ethanol, and eluted by 40% ethanol. Bidistribution in mice was determined after intravenous injection. RESULTS: The total chemical yield of tosylated flumazenil derivative was ~40%. The efficiency of labeling 3-(2-[F-18]fluoro)flumazenil was 66% with a total synthesis time of 50 min. Brain uptakes of 3-(2-[F-18]fluoro)flumazenil at 10, 30, 60 min after injection, were 2.5+/-0.37, 2.2+/-0.26, 2.1+/-0.11 and blood activities were 3.7+/-0.43, 3.3+/-0.07, 3.3+/-0.09%ID/g, respectively. CONCLUSION: We synthesized a tosylated flumazenil derivative which was successfully labeled with no-carrier-added F-18 by nucleophilic substitution.

Interrupted aortic arch may be defined as a discontinuity of the aortic arch. This uncommon anomaly was first described by Steidele in 1778 and was later classified into 3 types by Celoria and Patton. We experienced the case of a 25-year-old male with an interrupted aortic arch(Type B) which was well supplied by collateral circulations. Ligation of collateral supplies and a Y-graft replacement from ascending aorta to descending thoracic aorta and left subclavian artery was done. Postoperative aortogram revealed no collateral circulations and good continuity of the aorta without narrowing of the anatomic site. During the period of 2-month follow up, the patient was able to lead a relatively active life.

OBJECTIVE: We compared the expression pattern of progesterone receptor, integrin 3, cyclooxygenase-2 (COX-2) in in-phased endomerium of patient with the disease related implantation and control group, and tried to confirm the clinical efficacy of the immunohistochemical markers for discrimination of occult uterine receptivity defect in in-phase endometrium. STUDY DESIGN: Endometrial tissues were obtained from 60 women with normal (group 1; n = 20), uterine synechiae (group 2; n = 15), and endometriosis (group 3; n = 25). On 7 ~ 8 days after ovulation (POD 7 ~ 8), sex hormone levels were measured and immunohistochemical staining of PR, integrin 3, and COX-2 expression were performed. RESULTS: PR was decreased in the group 2 and increased in the group 3 comparing with the group 1. integrin 3 expression was significantly decreased in the group 2 and 3. COX-2 expression was significantly decreased in the group 2. But, in the group 3, COX-2 expression was slightly increased in glandular epithelial cells, and significantly increased in stromal cells. CONCLUSIONS: In-phase biopsies from patients with endometriosis and uterine synechiae showed different expression pattern of integrin 3, COX-2, and PR compared to the control. The aberrant expression of immunohistochemical markers be associated with occult uterine receptivity defect and produce the useful diagnostic method.

The rate of malignant transformation in porokeratosis (PK) lesions is approximately 7.5%, and linear PK demonstrates the highest rate of malignancy. An 83-year-old woman presented with a rapidly enlarging mass on her left arm. Variably sized erythematous scaly patches were scattered across the left half of her trunk and arm. Additionally, generalized variably sized brownish annular patches with a hyperkeratotic outer ring were observed on her face, trunk and bilateral arms. A skin biopsy was performed on 3 lesions-a yellowish to erythematous appearing mass, an erythematous scaly patch, and a brownish annular patch. Histopathological evaluation of these 3 lesions revealed squamous cell carcinoma, actinic keratosis, and PK, respectively. The final diagnosis was disseminated superficial PK with linear PK on the left side of the body, and actinic keratosis and squamous cell carcinoma confined to the linear PK lesions. We report a case which represents the progressive and stepwise malignant transformation of PK into squamous cell carcinoma.

BACKGROUND: Linezolid, an oxazolidinone, has shown efficacy in the treatment of adults with nosocomial or community-acquired pneumonia, skin and soft tissue infections (SSTI), and infections due to methicillin-resistant Staphylococcus aureus. We have taken part in the study for evaluation of efficacy and safety of linezolid for the treatment of suspected or proven gram-positive SSTI in Asia. We sub-analyzed and reported the results of the study among Korean patients. MATERIALS AND METHODS: A total of 60 patients were enrolled in the study for evaluation of efficacy and safety of linezolid for the treatment of gram-positive SSTI at eight teaching hospitals in Korea. We investigated patients' medical history, physical examination and laboratory study. Patients were regularly followed up to evaluate clinical response, laboratory changes, and adverse event up to 4 weeks after treatment. When possible, we performed microbiological study before and after treatment. RESULTS: A total of 60 patients were enrolled. Average age of the patient was 50.9+/-15.3 years old with male to female ratio being 1.3:1. Cellulitis, open wound infection, skin abscess, and other clinical manifestations were observed in 47 (78.3%), 6 (10.0%), 2 (3.3%), and 5 (8.3%) patients, respectively. Forty two patients completed both follow-up and treatment and among them, treatment was successful in 38 patients (90.5%) and unsuccessful in 4 patients (9.5%). Microoranisms were isolated from seven patients and 14 isolates were documented; 11 S. aureus, 3 coagulase-negative staphylococcus. Among the seven patients, bacteria were eradicated in four patient and the organism proved to be colonization in three patients. The most frequent drug-related adverse events were gastrointestinal (21.7%), hematologic and biochemical (21.7%) and neurologic (3.3%), in decreasing order. Nausea (15%) was the most frequent symptom and there were no serious side effects related to linezolid. CONCLUSION: Linezolid was effective and safe in treatment of gram-positive SSTI.
