Many chemotherapeutic agents induce variable cutaneous adverse reactions. Among the side effects, Stevens-Johnson syndrome is rare, but a fatal complication. There are two prior reports of cytosine arabinoside (ARA-C) induced toxic epidermal necrolysis, which is considered in the continuum of Stevens- Johnson syndrome. The prior cases were female patients under 16 years old with acute lymphocytic leukemia. We treated a 77-year-old man with recurrent mantle cell lymphoma who developed Stevens- Johnson syndrome after high dose ARA-C therapy. This is the first case of ARA-C induced Stevens- Johnson syndrome in Korea.

Fitz-Hugh-Curtis syndrome, a kind of perihepatitis, occurs approximately in 3 to 10 percent of patients with pelvic inflammatory disease. It is not easy to detect in clinical settings due to requirement of invasive methods for diagnosis, for example, like a laparoscopic examination. Now, it has become possible to recognize it easily with the aid of non-invasive methods including an abdominal dynamic CT scan and laboratory tests. Moreover, it can be improved after the oral administration of antibiotics. Therefore, noninvasive diagnosis is desirable. Herein, clinical characteristics of ten cases of Fitz-Hugh-Curtis syndrome are reported, with a review of the literature.

BACKGROUND: Pressure-controlled ventilation (PCV) is frequently used recently as the initial mode of mechanical ventilation in the patients with respiratory failure. Theoretically, because of its high initial inspiratory flow, pressure-controlled ventilation has lower peak inspiratory pressure and improved gas exchange than volume-controlled ventilation (VCV). But the data from previous studies showed controversial results about the gas exchange. Moreover, the comparison study between PCV and VCV with various inspiration:expiration time ratios (I:E ratios) is rare. So this study was performed to compare the respiratory mechanics and gas exchange between PCV and VCV with various I:E raitos. METHODS: Nine patients receiving mechanical ventilation for respiratory failure were enrolled. They were ventilated by both PCV and VCV with various I:E ratios (1:2, 1:1.3 and 1.7:1). FiO2, tidal volume, respiratory rate and external positive end-expiratory pressure (PEEP) were kept constant throughout the study. After 20 minutes of each ventilation mode, arterial blood gas, airway pressures, expired CO2 were measured. RESULTS: In both PCV and VCV, as the I:E ratio increased, the mean airway pressure was increased, and PaCO2 and physiologic dead space fraction were decreased. But P(A-a)O2 was not changed. In all three different I:E ratios, peak inspiratory pressure was lower during PCV, and mean airway pressure was higher during PCV. But PaCO2 level, physiologic dead space fraction and P(A-a)O2 were not different between PCV and VCV with three different I:E ratios. CONCLUSION: There was no difference in gas exchange between PCV and VCV under the same tidal voulme, frequency and I:E ratio.

PURPOSE: Recent studies show positive association of early repolarization (ER) with the risk of life-threatening arrhythmias in patients with coronary artery disease (CAD). This study was to investigate the relationships of ER with myocardial scarring and prognosis in patients with CAD. MATERIALS AND METHODS: Of 570 consecutive CAD patients, patients with and without ER were assigned to ER group (n=139) and no ER group (n=431), respectively. Myocardial scar was evaluated using cardiac single-photon emission computed tomography. RESULTS: ER group had previous history of myocardial infarction (33% vs. 15%, p<0.001) and lower left ventricular ejection fraction (57+/-13% vs. 62+/-13%, p<0.001) more frequently than no-ER group. While 74 (53%) patients in ER group had myocardial scar, only 121 (28%) patients had in no-ER group (p<0.001). During follow up, 9 (7%) and 4 (0.9%) patients had cardiac events in ER and no-ER group, respectively (p=0.001). All patients with cardiac events had ER in inferior leads and horizontal/descending ST-segment. Patients with both ER in inferior leads and horizontal/descending ST variant and scar had an increased adjusted hazard ratio of cardiac events (hazard ratio 16.0; 95% confidence interval: 4.1 to 55.8; p<0.001). CONCLUSION: ER in inferior leads with a horizontal/descending ST variant was associated with increased risk of cardiac events. These findings suggest that ER in patients with CAD may be related to myocardial scar rather than pure ion channel problem.

Following the implementation of a long-term care insurance system for the elderly in Korea, many nursing homes have been established and many more patients than ever before have been living at nursing homes. Despite the fact that this is a high-risk group vulnerable to hip fractures, no study has yet been conducted in Korea on hip fracture incidence rates and prognoses among patients residing at nursing homes. We recently studied 46 cases of hip fracture in nursing homes; more specifically, we investigated the most common conditions under which fractures occur, and examined the degree of recovery of ambulatory ability and the mortality within 1 yr. Among those who had survived after 1 yr, the number of non-functional ambulators increased from 8 hips before hip fracture to 19 hips at final post-fracture follow-up. These individuals showed poor recovery of ambulatory ability, and the number who died within one year was 11 (23.9%), a rate not significantly different from that among community-dwelling individuals. It was evident that hip-joint-fracture nursing home residents survived for similar periods of time as did those dwelling in the community, though under much more uncomfortable conditions. The main highlight of this report is that it is the first from Korea on nursing home residents' ambulatory recovery and one-year mortality after hip fracture. The authors believe that, beginning with the present study, the government should collect and evaluate the number of hips fractured at nursing facilities in order to formulate criteria that will help to enable all patients to select safer and better-quality nursing facilities for themselves or their family members.

INTRODUCTION: Adult stem cells generate differentiated cells beyond their own tissue boundaries. To prove that stem cells derived from bone marrow is capable of therapeutic application in cerebral ischemic patients, we performed this study. MATERIAL AND METHOD: We transplanted adult stem cells derived from bone marrow of the patient's iliac bone to 5 patients with cerebral infarction. Of 5 patients, two patients had internal carotid artery occlusion, two patients had severe stenosis of the middle cerebral artery, remaining one patient had occlusion of the branch of the middle cerebral artery. At first, we performed extracranial-intracranial bypass surgery in all patients, and then implanted bone marrow stem cell in the infarcted brain and boder zone area directly under the microscopic navigator and also injected bone marrow stem cells through the grafted vessel to the infarcted area. Two weeks after bypass surgery, we confirmed the patency of bypass graft with external carotid angiography. In the same setting, mesenchymal stem cells acquired from autologous bone marrow were superselectively injected into the bypass graft via a microcatheter. Postoperative evaluation of the patients was decided to the neurological status and the degree of reduction of the high signal area on the T2 image of the postoperative MRI. RESULT: All patients who underwent bypass surgery with stem cell implantation had an uneventful postoperative course and showed some improvement of preoperative neurologic dysfunction. Postoperative significant improvement of cerebral vasoreactivity to acetazolamide was showed in all patients. On postoperative 3 months MRI, three patients showed significant reduction of the high signal area on the T2 image, and also improved neurological status on those patients. Other one patient showed moderate degree of the reduction of the high signal area on T2 image of the postoperative MRI, but neurological status of that patient slightly improved. Remaining one patient who showed poor circulation via bypass graft does neither reduction of the high signal area on T2 image of the postoperative MRI nor improvement of the neurological status of that patient. CONCLUSION: In patients of fixed cerebral infarction with major neurologic deficit, EC-IC bypass surgery is not effective, even though infarcted area filled by grafted vessel extensively. In those patients, autologous bone marrow stem cell implantation combined with bypass seems to be expect neuronal regeneration.

OBJECTIVE: This study is designed to elucidate the requirements for angiographic evaluation and the selection of appropriate therapeutic approaches in patients who had strongly suggestive traumatic carotid arterial lesions. METHODS: Ten cases of traumatic internal carotid arterial lesions were analysed in this study. Injury mechanisms, neurological status, computed tomography scans, pre-and postoperative angiograms, and methods and results of the treatment were included. RESULTS: Of 10 cases, carotid-cavernous fistula(CCF) alone in three, CCF with intracranial pseudoaneurysms in three, pseudoaneurysm with dissection in one, extracranial internal carotid artery thrombosis in one, extracranial pseudoaneurysm in one, and the remaining one had all of the CCF, intracranial pseudoaneurysm and dissection. Seven of these 10 cases had sphenoid sinus wall fractures and six had subarachnoid hemorrhage. Six cases were treated with endovascular techniques, and four with direct parent artery occlusion and bypass surgery. No postoperative morbidity or additional permanent neurological deficits occurred except one patient who suffered from reperfusion hemorrhage after bypass surgery. CONCLUSION: Head trauma patients with facial bone fractures and thick subarachnoid hemorrhage should be evaluated for the development of traumatic injuries to the carotid artery as soon as possible. Endovascular treatment to these lesions have come to play an increasing role. Patients with traumatic internal carotid artery lesions who do not tolerate test occlusion require extracranial to intracranial bypass surgery before occlusion.

OBJECTIVES: The aim of this study was to evaluate changes of body composition in cirrhotic patients. Dual energy x-ray absorptiometry (DEXA) and anthropometry were used, and the values obtained were compared. METHODS: Mid-arm fat and muscle areas were calculated by anthropometry in 66 cirrhotic patients and 94 healthy controls. In 37 of the cirrhotic patients and 39 of the controls, fat mass, lean soft tissue mass and bone mineral contents were measured with DEXA. RESULTS: The number of cirrhotic patients with measured values below the fifth percentile of normal controls was 21 (31.8%) by mid-arm fat area, six (9.1%) by mid-arm muscle area, 15 (40.5%) by fat mass and 0 (0%) by lean soft tissue mass. The fat mass in cirrhotic patients was less than in controls, whereas lean soft tissue mass and bone mineral content were not different. Fat depletion was severe in Child-class C patients and with severe ascites. Mid-arm fat area and fat mass showed close correlation (r = 0.85, p < 0.01), but mid-arm muscle area and lean soft tissue mass showed poor correlation (r = 0.32, p < 0.05). CONCLUSION: Cirrhotic patients showed lower fat component, with preserved lean soft tissue mass and bone mineral content. In clinical practice, the measurement of mid-arm fat area was useful for the assessment of fat mass.

PURPOSE: Electric cardioversion has been successfully used in terminating symptomatic atrial fibrillation (AF). Nevertheless, largescale study about the acute cardiovascular events following electrical cardioversion of AF is lacking. This study was performed to evaluate the incidence, risk factors, and clinical consequences of acute cardiovascular events following electrical cardioversion of AF. MATERIALS AND METHODS: The study enrolled 1100 AF patients (mean age 60+/-11 years) who received cardioversion at four tertiary hospitals. Hospitalizations for stroke/transient ischemic attack, major bleedings, and arrhythmic events during 30 days post electric cardioversion were assessed. RESULTS: The mean duration of anticoagulation before cardioversion was 95.8+/-51.6 days. The mean International Normalized Ratio at the time of cardioversion was 2.4+/-0.9. The antiarrhythmic drugs at the time of cardioversion were class I (45%), amiodarone (40%), beta-blocker (53%), calcium-channel blocker (21%), and other medication (11%). The success rate of terminating AF via cardioversion was 87% (n=947). Following cardioversion, 5 strokes and 5 major bleedings occurred. The history of stroke/transient ischemic attack (OR 6.23, 95% CI 1.69-22.90) and heart failure (OR 6.40, 95% CI 1.77-23.14) were among predictors of thromboembolic or bleeding events. Eight patients were hospitalized for bradyarrhythmia. These patients were more likely to have had a lower heart rate prior to the procedure (p=0.045). Consequently, 3 of these patients were implanted with a permanent pacemaker. CONCLUSION: Cardioversion appears as a safe procedure with a reasonably acceptable cardiovascular event rate. However, to prevent the cardiovascular events, several risk factors should be considered before cardioversion.

Central diabetes insipidus (DI) is a syndrome characterized by thirst, polydipsia and polyuria. Langerhans cell histiocytosis is one of the etiologies of DI. Recently we experienced a central DI associated with Langerhans cell histiocytosis. The 44 years old female patient complained right hip pain, polydipsia and polyuria. We carried out water deprivation test. After vasopressin injection, urine osmotic pressure was increased from 109 mOsmol/kg to 327 mOsmol/kg (300%). Brain MRI showed a thickened pituitary stalk and air bubble like lesions sized with 5cm, 7cm was shown on fifth L-spine and right hip bone at hip bone CT. CT guided biopsy revealed abnormal histiocytes proliferation and abundant lymphocytes. The final diagnosis was central DI associated with systemic Langerhans cell histiocytosis invading hip bone, L-spine and pituitary stalk. Desmopressin and etoposide chemotherapy were performed to the patient.
