The clinical presentation of pheochromocytoma is variable. The classic symptoms are headache, diaphoresis, and tachycardia, with paroxysmal hypertension. Other less common cardiovascular manifestations, such as arrhythmias, angina pectoris, acute myocardial infarction, dilated cardiomyopathy, and acute heart failure, have been reported occasionally. We present the case of a middle-aged woman who had stress-induced cardiomyopathy with a left ventricular thrombus, due to the pheochromocytoma. The thrombus was embolized to the aorto-iliac bifurcation during hospitalization. We removed the thrombus by a catheter thromboembolectomy and performed a surgical left adrenalectomy. After the operation, all of her symptoms and the underlying diseases (hypertension, hyperglycemia, heart failure, dyslipidemia) resolved.

Regional anesthesia is mostly used in operations on the lower abdomen or lower extremities in elderly patients. It shows nearly no difference in long-term outcomes compared to general anesthesia, but it is used more often because of the several advantages. However, during the regional anesthetic procedures, the patient must cooperate and has to be lateral decubitus position without physical movement. Therefore, in the case of the patients who are not cooperated, it may be not easy to perform regional anesthesia. In this study, we present 3 case reports that regional anesthesia after sedation is performed in un-cooperated patients. Regional anesthesia after sedation may be a good method to improve outcomes in un-cooperated elderly patients.

Acute pulmonary embolism is considered a cardiovascular emergency and is one of the most important causes of morbidity and mortality in hospitalized patients. Tumor embolism is a rare and unique complication of malignancies, and detached thrombi or tumors may cause massive pulmonary embolism in patients with malignancies. The identification of the type of pulmonary embolism is critical because treatment and prognosis vary considerably. We report an unusual presentation of a tumor embolism that was misdiagnosed as a pulmonary thromboembolism in a young woman. The patient was initially treated with the anti-coagulants warfarin and aspirin, but her symptoms were aggravated after two months and she required emergency surgery. Histology revealed a pulmonary embolism due to metastatic chondrosarcoma. Following surgery, her condition deteriorated, and she did not survive. This case highlights the need to investigate the cause of pulmonary embolism should the patient not respond to anti-coagulatant therapy.

BACKGROUND: Acute intracranial large-artery occlusions (AILAOs) are detected frequently and cause severe neurological disabilities. Most studies in this field do not focus on the natural history of AILAOs, but on the individual prognosis for each intervention. The aim of this study was to elucidate the clinical profiles and outcomes of AILAOs. METHODS: A consecutive series of patients hospitalized between January 2004 and October 2007 due to AILAO within 24 hours from onset were recruited. Based on a prospective stroke registry, their clinical profiles were collected. AILAO was defined as an intracranial internal carotid artery (ICA), middle cerebral artery (MCA), or basilar artery (BA) occlusion that could be confirmed by angiography, with relevant lesions on diffusion-weighted imaging (DWI). The modified Rankin Scale (MRS) score at 3 months and the recanalization rate within 14 days were recorded as outcomes. RESULTS: Among 1,047 patients with acute ischemic stroke who were examined within 24 hours of onset, 189 [18.1%; 101 men, 88 women; age 68.6+/-13.0 years (mean+/-SD); median National Institutes of Health Stroke Scale (NIHSS) score=11]. Occlusion sites were MCA M1, MCA M2, distal ICA, and BA in 99 (52.4%), 50 (26.5%), 20 (10.6%), and 20 (10.6%) of cases,respectively. Embolic sources were found in 103 (54.5%) cases. MRS scores were available for 184 (97.4%) of the patients, of which 78 had a favorable outcome (MRS: 0.2). Follow-up angiography was performed in 122 (64.6%) cases, with recanalization observed in 88 (72.1%) of these. Thrombolysis, occlusion site, presence of an embolic source, and initial glucose level were predictors of early recanalization (p<0.001). Recanalization status and initial NIHSS score were strongly correlated with a favorable outcome (p<0.005). CONCLUSIONS: This is the first report of the clinical profiles, outcomes, and their predictors in a cohort of Korean patients with AILAO.

There have been a few reports of hemophagocytic lymphohistiocytosis (HLH) with chromosomal abnormalities. Clonal chromosomal abnormalities in HLH patients are usually found in association with hematologic malignancies and rarely with epstein-barr virus (EBV) infection. Here, we report a fatal case of HLH with clonal karyotype abnormalities. A 75-yr-old man was admitted with persistent anorexia and high fever. Laboratory data revealed pancytopenia, hypofibrinogenemia, hyperferritinemia, prolonged prothrombin time and activated partial thromboplastin time, and marked elevated level of serum transaminases. In real time-PCR using whole blood, EBV DNA was not detected but cytomegalovirus (CMV) DNA was detected. The bone marrow aspiration smear showed hyperplasia of mature histiocytes with prominent hemophagocytosis. In chromosomal analysis of bone marrow aspirates, complex chromosomal abnormalities were found. In spite of steroid pulse therapy and antibiotic treatment, he died of disseminated intravascular coagulopathy.

A 35-year-old Korean man with a 10-year history of ulcerative colitis (UC) presented with pain and swelling of the right neck. The patient was diagnosed with Takayasu's arteritis (TA) and had human leukocyte antigen (HLA) B-52, which is frequently found in patients having both UC and Takayasu's disease concurrently on HLA analysis. This case is the first report of a patient with both TA and UC in Korea, to the best of our knowledge.

Flecainide acetate is a potent class Ic anti-arrhythmic drug with a major sodium channel-blocking effect. Flecainide toxicity can cause myocardial impairment and precipitate circulatory collapse, particularly in patients with renal failure. Electrical and hemodynamic deterioration during flecainide toxicity may not respond to conventional treatments. We report the successful management of flecainide toxicity using extracorporeal membrane oxygenation (ECMO), hemoperfusion, and bicarbonate administration maintaining alkalinity.

This study is an analysis of types of patients and distribution of implant site and survival rate of Xive(R) implant. The following results on patient type, implant distribution and survival rate were compiled from 324 implant cases of 140 patients treated at the periodontal dept. of Yonsei University Hospital and G dental clinic between February 2003 and April 2006. 1. There are no dissimilarities between men and women, with patients in their 30, 40, 50s accounting for 80% of patients and accounted for 82% of implant treatments; the largest share of patients and implant treatments. 2. Mn. posterior area accounted for 57% of implant treatments followed by Mx. posterior area(29%), Mx. anterior area(8%) and Mn. anterior area(6%). 3. Partial edentulous patients treated by single crown and bridge-type prosthesis accounted for 96% and fully edentulous patient accounted for the remaining 4%. 4. The major cause of tooth loss is periodontal disease, followed by dental caries, trauma and congenital missing. 5. The distribution of bone quality for maxillae was 54.2% for typeIII, followed by 30.8% for type II, 15% for typeIV and 0% for typeI. As for mandible, the distribution was 63% for typeII, followed by 34% for typeIII, 2.5% for typeI and 0.5% for typeIV. 6. The distribution of bone quantity for maxillae was 55% for type C, followed by 35% for type B, 8% for type D and 2% for type A. As for mandible, the distribution was 60% for type B, followed by 32% for type C, 7% for type A and 0% for type D. 7. The majority of implants were those of 9.5-13 mm in length(95%) and regular diameter in width(82%). 8. The total survival rate was 98%. The survival rate was 97% in the maxillae region and 99% in the mandible region. 9. The survival rate in typeI was 83%, in typeII was 99%, in typeIII was 97% and in typeIV was 100%. As for the bone quantity, the survival rate in type A and D(100%) was most, followed by type B(99%) and type C(96%). The results showed that Xive(R) implant could be used satisfactorily compare for the other implant system. But we most to approach carefully in certain extreme condition especially with poor bone quality and quantity.
