PURPOSE: The purpose of the experiment with the rabbit was to evaluate the effect of human amniotic membrane transplantation in the extraocular muscle surgery area after the operation. METHODS: Five millimeters resection of both superior rectus muscles was performed in eight rabbits. The left eye was served as a control, and the right eye was covered with human amniotic membrane at the site where the operation was performed. Each rabbit was graded according to the degree of adhesion. A histological comparison was done after enucleation. RESULTS: At one week after the operation, it was discovered that the inflammation of the human amniotic membrane transplantation site was suppressed, but at two weeks the human amniotic membrane transplantation site was significantly inflamed. However, the inflammation decreased at six weeks. CONCLUSIONS: This study shows that strabismus surgery with transplantation of human amniotic membrane may reduce postoperative inflammation and adhesion in strabismus surgery after one week. However, after two weeks the inflammation will increase and produce more postoperative adhesion. After six weeks there was no significant inflammation in comparison to the control group.

Gastrointestinal involvement has been reported to occur in about 5 to l0% of patients with lymphoma. The most common gastrointestinal site for a lymphoma is the stomach, followed by the small intestine and ileocecal region. When lymphoma is found in the esap us, generally it is with contiguous involvement of the gastric fundus, the cervical node, secondary to mediastinal lymph node compression, or a late manifestation of advanced desease. Such cases cannot be labeled as primary esophageal lymphoma. A search of the literature reveals that there have been about 20 or more published cases classified as esophageal lymphoma. However, more than ten cases are indistingishable from the case of distal esophageal involvement by gastric lymphoma. In 1935, Chiolero described a case of midesophageal stricture, which at autopsy was consistent with Hodgkin's disease for the first time. Berman reported an authentic case of primary histiocytic lymphoma confined to the lower esophagus. Only six or more cases were reported in literature until the present time. Here, a 30-year-old man with substernal discomfort was shown to have a mass lesion on the esophagus. The mass was proved to be malignant lymphoma on the histologic examination. This may be the first report dealing with spontaneous regression of maligant lymphoma of the esophagus possibly associated with the use of cimetidine.

The majority of lung cancers associated with hyperamylasemia are adenocarcinomas. Here we report an unusual case of a 54-year-old male patient who complained of dyspnea, anterior chest wall discomfort and facial edema for one month, presenting with a huge mediastinal mass and hyperamylasemia complicated by pericardial effusion Histological evaluation of mediastinal mass revealed small cell carcinoma and pericardium showed nonspecific inflammation with fibrosis. The serum amylase had an electrophoretic mobility similar to that of salivary gland enzyme. There were no evidence of a salivary or pancreatic causes of hyperamylasemia. After chemotherapy, parenchymal lung lesions improved and hyperamylasemia disappeared. For the mannagement of peracardial effusion a pericardial window was forms(i. We concluded that the striking increase in serum amylase was due to the ectopic production of this enzyme by the tumor.

Locked-in Syndrome is a severe pontine stroke causing quadriplegia, lower cranial nerve paralysis, and mutism with preservation of only vertical gaze and upper eyelid movement in a conscious patient. We present a case of a Locked-in Syndrome patient who received communication training with augmentative and alternative communication equipment by using eye blinks. After 3 weeks of training, the patient was able to make an attempt to interact with other people, and associate a new word by Korean alphabet selection. Augmentative and alternative communication equipment which uses eye blinks might be considered to be beneficial in improving the communication skills of locked-in syndrome patients.

Herpes simplex virus (HSV) infection of the lower respiratory tract occurs rarely in neonate and immunocompromised host. The need for a timely and specific diagnosis of viral infections is becoming greater with development of antiviral chemotherapy. Herein, we report a case of herpes simplex virus pneumonia diagnosed by cytologic examination of the bronchoalveolar lavage (BAL) sample of respiratory epithelial cells in a tracheal adenoid cystic carcinoma patient. A 65-year-old woman presented with dyspnea and cough for one month. Bronchoscopy showed a mass arising from the posterior wall of upper trachea, and she underwent tracheal sleeve resection with cricotracheal anastomosis. The pathologic examination revealed adenoid cystic carcinoma. Corticosteroids were used for prevention of stenosis and swelling on the anastomosis site. On 28th postoperative day, pneumonia developed and it was aggravated despite of antibiotic therapy. The cytologic examination of the BAL fluid showed the eosinophilic nuclear inclusion along with the positive result of immunocytochemistry using monoclonal antibody to HSV. Despite of immediate therapy with acyclovir the pneumonia progressed to the acute respiratory distress syndrome and the patient eventual died.

Pure red cell aplasia (PRCA) is characterized by severe anemia with reticulocytopenia and absence of erythroblast from the bone marrow. Sinus histiocytosis with massive lymphadenopathy (SHML : Rosai-Dorfman disease) is rare systemic disease characterized by painless cervical, axillary, inguinal and mediastinal lymphadenopathy and frequent extranodal invasion. Histologically, lymph node sinuses are expanded by numerous distinctive histiocytes which contains well preserved lymphocytes. We report a case of sinus histiocytosis with massive lymphadenopathy in inguinal lymph node biopsy with polyclonal gammopathy and pure red cell aplasia in bone marrow biopsy who was infected by Epstein-Barr virus.

BACKGROUND: Aortic stiffness and intima-media thickness (IMT) are known to be associated with ischemic stroke. The aim of the present study was to investigate the differences of aortic stiffness and IMT between cerebral infarction (CI) and transient ischemic attack (TIA). METHODS: A total of 500 patients with acute stroke were divided into 2 groups: the TIA group (n = 230, 62.4 +/- 12 years, 144 males) versus CI group (n = 270, 63.4 +/- 11 years, 181 males). Aortic stiffness index and IMT, as well as conventional cardiovascular risk factors, were compared. RESULTS: The prevalence of hypertension, diabetes, and dyslipidemia were significantly higher, and left atrial volume and E/E' were significantly elevated in the CI group than in the TIA group. Carotid IMT was significantly thicker in the CI group than in the TIA group. Aortic stiffness index beta was significantly higher (7.99 +/- 2.70 vs. 7.02 +/- 4.30, p = 0.043) and aortic IMT was significantly thicker (1.53 +/- 0.41 vs. 1.45 +/- 0.39 mm, p = 0.040) in the CI group than in the TIA group. Aortic stiffness index beta was significantly correlated with the IMT of the aorta (r = 0.279, p = 0.014), right (r = 412, p < 0.001) and left carotid artery (r = 441, p < 0.001). CONCLUSION: Aortic stiffness index beta and IMT were significantly higher in patients with CI than TIA. The result of the present study suggested that CI is associated with more advanced degree of atherosclerotic and arteriosclerotic process than TIA.

OBJECTIVE: To investigate the usefulness of cardiac biomarkers in the evaluation of prognosis and cardiac involvement (CI) in patients with acute aortic syndrome (AAS). METHODS: A total of 260 AAS patients with the measurements of cardiac biomarkers were divided into 2 groups; the survived (n=215, 60.6±13.7 years, 110 males) vs the dead (n=45, 64.5±13.6 years, 19 males). N-terminal pro-B-type natriuretic peptide (NT-proBNP), cardiac specific troponin-I (cTnI), C-reactive protein (CRP), creatinine kinase (CK), MB fraction of CK (CK-MB), and D-dimer were compared. RESULTS: NT-proBNP and D-dimer were significantly elevated in the dead group than in the survived group (3558.7±5497.2 vs 949.9±2307.3 pg/mL, p<0.001, 4.5±5.1 vs 2.0±3.2 ug/mL, p<0.001, respectively). CI was observed in 59 patients (22.7%), and NT-proBNP was significantly elevated in patients with CI than in patients without CI (2497.7±4671.3 vs 722.5±1489.1 pg/mL, p=0.034). In univariate analysis, Stanford type A, CI, NT-proBNP, and D-dimer were significantly associated with mortality, but NT-proBNP was the only significant independent predictor of mortality in multivariate analysis. By receiver operating characteristic curve analysis, the optimal cut-off value to predict mortality was 517.0 pg/mL for NT-proBNP (area under the curve 0.797, sensitivity 86.7%, specificity 71.7%). CONCLUSION: The elevation of cardiac biomarkers is not infrequent in patients with AAS. NT-proBNP is significantly associated with CI and is an independent predictor of mortality in patients with AAS. The measurement of NT-proBNP would be useful in the risk stratification of AAS.

BACKGROUND: To compare the effects of low dose and high dose of statin treatment on endothelial function and carotid intima-media thickness (IMT) in patients with variant angina (VAP). METHODS: A total of 70 patients with VAP were divided into two groups; atorvastatin 10 mg treatment group (group I: n = 35, 54.2 +/- 12.5 years) versus atorvastatin 40 mg treatment group (group II: n = 35, 52.6 +/- 9.8 years). Flow mediated vasodilation (FMD) of the brachial artery and IMT of the carotid artery were compared between the groups after 6 months of statin treatment. RESULTS: The baseline FMD and carotid IMT were not different between the groups. After 6 months of statin therapy, FMD was significantly improved in both groups (7.7 +/- 2.5% to 8.9 +/- 2.2% in group I, p = 0.001, 7.9 +/- 2.7% to 9.5 +/- 2.8% in group II, p < 0.001), but the degree of FMD change and FMD at 6 month were not different between the groups. Carotid IMT were not changed in both groups after 6 months of statin therapy. CONCLUSION: The use of statin for 6 months significantly improved endothelial function in patients with VAP, but carotid IMT was not changed. The use of high dose statin did not show significant additional benefit as compared with the use of low dose statin. The present study suggested that statin therapy would be beneficial in the treatment of VAP.
