A 34 year-old woman was hospitalized with anterior chest pain and indigestion. Chest radiograph and computed tomogram revealed a sewing needle in the cardiac cavity. She had no histories of surgical intervention, drug abuse, or acupuncture. We removed the needle from the right ventricle under cardiopulmonary bypass.

the ineidence of abdominal subcutaneous endometriosis is quite rare we have experienced one case of subcutaneous endometriosis. The typical clinical bistory and local findings of endometriasis enabk us to make the conect diagnosis. the treatment of choice is complete surgical excision of endometrial tissue and post operative medical therapy. This case was reported with a brief review of the comcemed literatures.

In the present study, the authors investigated the management of mechanical valve thrombosis (MVT). From January 1981 through March 2006, 2,908 mechanical valve replacements were performed in 2,298 patients at our institution. Twenty (0.87%) patients presented with MVT, 14 (70.0%) were women, and the mean age of the patients was 42.0+/-14.0 (27-66) yr. Thrombosis involved mitral in 14 (70.0%), aortic in 2 (10.0%), tricuspid/aortic in 1 (5%), and tricuspid in 3 (15%). The interval from first operation to valve thrombosis was 121.8+/-75.4 (0.9-284.7) months. The most frequent clinical presentation was heart failure (13/20, 65%), and predisposing causes of MVT were: poor compliance with warfarin (7), pregnancy (5), drug interaction (2), and unknown (6). All 20 patients underwent valve replacement: mitral (14, 70.0%), tricuspid (3, 15.0%), aortic (2, 10%) and tricuspid/aortic (1, 5%). One early death occurred due to left ventricular failure, but no late mortality occurred during 63.3+/-49.9 (0.5-165.1) months of follow-up. MVT was treated successfully, and pregnancy and inadequate anticoagulation were found to influence the occurrence of this rare complication.

Besides lung transplantation, pulmonary thromboembolectomy is the only effective therapeutic option for chronic thromboembolic pulmonary hypertension. It is however associated with a considerably high hospital mortality between 6.6 to 23%. Proper patient selection is critical when considering a patient for pulmonary thromboembolectomy. And It cannot be overemphasised that the key to the success of the operation is complete endarterectomy of the entire pulmonary arterial tree. We report that pulmonary thromboendarterectomy under total circulatory arrest was an effective and safe method in the surgical correction of the chronic thromboembolic pulmonary hypertension and enabled complete removal of superimposed peripheral organized thrombi in a good operative field.

OBJECTIVE: To plan the goals of the rehabilitation management after stroke, it was important to know functional prognosis of the patients. The purpose of this article was to predict functional outcomes of stroke patients by means of an analysis of the well-known prognostic factors of function at admission. METHOD: This study was performed retrospectively on 102 patients with acute stroke who were admitted to Department of Rehabilitation Medicine. The inpatients, clinical and functional evaluation were carried out at admission. Functional abilities were measured with the use of the Functional Ambulatory Category (FAC) and the modified Barthel Index (MBI). RESULTS: The significant prognostic factors of FAC improvement rate were age, National Institute of Health Stroke Scale (NIHSS), Morticity Index, MBI, Mini-Mental State Examination (MMSE), aphasia and Trunk Control Test (TCT) (p<0.01). The most valuable single factor of FAC improvement rate was TCT. The significant prognostic factors of MBI improvement rate were age, NIHSS, Morticity Index, MMSE, aphasia and TCT (p<0.01). The most valuable single factor of MBI improvement rate was TCT. CONCLUSION: We concluded that TCT could be the most valuable prognostic factor in rehabilitation management outcome of stroke.

OBJECTIVES: Delirium of hospitalized patients is common and it is significantly associated with increased mortality rate. Misdiagnosis rates of delirium are reported in a range of 36.7 to 63% in clinical setting. We aimed to identify the clinical features and symptomatic characteristics associated with misdiagnosis of delirium. METHODS: Subjects were 256 inpatients who were referred for psychiatric consultation and diagnosed with delirium by a psychiatrist at a university hospital between January 1 and June 30, 2012. Clinical data were obtained with retrospective chart review. Patients were divided into misdiagnosed group and correct diagnosed group, after reviewing the reason which were described in the consultation request form. RESULTS: Sixty nine(27%) subjects of the 256 patients were referred for other reasons(mood, substance, anxiety, dementia etc.) than "delirium/confusion" by clinician(misdiagnosed group). In misdiagnosed group, use of antipsychotics was more common. There were no differences between the two groups in age, gender, and department of referring clinician. Fluctuation score of DRS-R-98 was higher in the correct diagnosed group. CONCLUSIONS: In this study, the risk of misdiagnosis was higher when the patients have taken antipsychotics or less symptom fluctuation. Careful clinical attention is needed for diagnosis for delirium in these patients.

Prostaglandin E1 (PGE-1) is a potent vasodilator, which also inhibits platelet aggregation, affects the blood flow viscosity, and fibrinolysis. The compound also excerts anti-inflammatory effects by inhibiting the monocyte and neutrophil function. PGE-1 has been widely administered following microvascular flap surgery, along with perioperative antithrombotic agents such as low molecular weight heparin or aspirin, showing excellent results. We report a case showing successful salvage recovery from post-traumatic ischemic necrosis of the finger via PGE-1 assisted conservative treatment.

OBJECTIVE: The objective of this study was to determine relationship between alteration of expression of E-cadherin, beta-catenin and tumor progression, clinical stage, lymph node metastasis, age of patients with uterine cervical cancer. METHODS: The authors evaluated the immunohistochemical expression pattern of E-cadherin and beta- catenin in relationship with tumor stage and clinicopathologic parameters in 71 cervical neoplasia including 36 cases of squamous cell carcinoma (SCC), 10 cases of microinvasive SCC, 22 cases of squamous cell carcinoma in situ, and 3 cases of severe dysplasia. RESULTS: There were aberrant expression in 76.1% of E-cadherin (54 of 71) and 74.6% of beta-catenin (53 of 71) in the cervical cancer. There was positive correlation of aberrant expression of E-cadherin with tumor progression and clinical stage (<0.005). There was positive correlation of aberrant expression of beta- catenin with tumor progression and clinical stage (<0.005). CONCLUSION: These results suggest that the degree or the pattern of E-cadherin, beta-catenin, and E-cadherin/beta-catenin complex may be related to histologic grade and clinical stage of uterine cervical cancer.
