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.

Perfusion scintigraphy has proved to be an essential part for the diagnosis of pulmonary thromboembolism. The wedge shaped perfusion defect extending to lung base is a highly probable finding of pulmonary embolism. Occasionally, great perfusion defects could be presented as a false positive finding under the circumstance of nonthromboembolic origin, such as neoplastic compression or invasion of pulmonary artery. We report an unusual case of massive perfusion defect resulting from pulmonary arterial compression by bronchogenic carcinoma. A 71-year-old man visited our hospital because of productive cough and was diagnosed as bronchogenic carcinoma. The perfusion scintigraphy showed unilateral total defect of lung, not accompanied by any clinical evidence of thromboembolism. A contrast enhanced computed tomogram showed heterogeneous mass shadow in left hilum, abutting to the descending aorta and compressing left main pulmonary artery. These findings suggested a nonembolic mechanism of perfusion defects which were produced by the neoplastic compression of pulmonary artery.

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.

Allergic response to common environmental agents has been regarded as a main pathogenetic mechanism of bronchial asthma. However, allergic sensitization (atopy) can not be detected in a siginificant number of adult asthmatic patients. The etiology of nonatopic asthma has not yet been defined. To evaluate the possible involvement of autoimmune response against bronchial mucosa in the pathogenesis of nonatopic asthma, we performed indirect immunofluorescence staining of fresh frozen human bronchial mucosa tissue using serum samples from patients with atopic and nonatopic asthma, healthy controls, and patients with systemic lupus erythematosus. On immunostaining, circulating IgG autoantibodies against bronchial mucosa were detected in 2 (9.1%) of 22 patients with nonatopic asthma and in none of 22 patients with atopic asthma and of 22 healthy controls. IgG autoantibodies from the two patients with nonatopic asthma predominantly stained the cytoplasmic membrane of basal cells in bronchial epithelium. Serum samples from 10 patients with systemic lupus erythematosus immunostained the nucleus of epithelial cells in whole layer of bronchial epithelium. This study showed the presence of circulating IgG autoantibodies against the bronchial epithelial cell in a small portion of patients with nonatopic asthma. Further studies may be necessary to evaluate the possible involvement of autoimmune mechanism in the pathogenesis of nonatopic asthma.

We present a case of metameric arteriovenous malformation (AVM) in a neonate. The neonate appeared normal, except for a dimple and blue discoloration in the lower thoracic spine. Spinal ultrasonography revealed cutaneomeningiospinalangiomatosis in the thoracic spine. Spinal magnetic resonance imaging revealed a definite metameric AVM at the T10-T11 level and a cutaneous hemangioma at T11. The neonate was conclusively diagnosed with spinal metameric AVM at the T10-T11 level. The neonate was asymptomatic with no, abnormal physical or neurological complications, including urinary incontinence, fecal incontinence, or muscle weakness.

PURPOSE: The present study was conducted to determine and compare the target attainment rate (TAR) between microorganism-nonspecific (Ctrough) and microorganism-specific (AUC24/MIC) targets over two weeks of teicoplanin administration according to several dose regimens for the treatment of Staphylococcus aureus in Korean patients with neutropenic fever. MATERIALS AND METHODS: One thousand virtual concentrations were obtained for each dose using the population pharmacokinetic parameters of teicoplanin adopted from a published study. Simulation of 1,000 virtual MICs was performed using the MICs of 78 clinical isolates of S. aureus collected from a hospital in Korea. Thereafter, these simulated MICs were randomly allocated to 1,000 virtual patients in whom the TARs for AUC24/MIC >125 [or 345] and Ctrough >10 [or 20] mg/L were determined. The relationship of the maintenance dose with the steady-state TAR was predicted with respect to the AUC24/MIC >125 [or 345] using logistic analysis. RESULTS: The standard dose regimen of teicoplanin showed TARs of about 70% [or 33%] and 70% [or 20%] at steady-state in cases with AUC24/MIC >125 [or 345] and Ctrough >10 [or 20] mg/L, respectively. CONCLUSION: The current standard dose regimen was predicted to be insufficient to adequately treat S. aureus in Korean patients with neutropenic fever. To assure at least an 80% TAR in this population, dose adjustment of teicoplanin should be considered.

PURPOSE: Glomus tumor is rare benign neoplasm arising from the normal glomus, which is a neuromyoarterial apparatus, usually seen in the nail bed of fingers. Concerning about the origin, there were few written reports about extra-digit glomus tumor of elderly patient. MATERIALS AND METHODS: A 69-year-old man presented with severe pain and tenderness localized to the distal dorsal portion of forearm for 5 years. The pain was sudden in onset resting several seconds, cold frequently exacerbated these symptoms. So much pain was caused by touching the sensitive area that the patient was quite reluctant to have the maneuver repeated. The clinical suspicion of glomus tumor was made and the lesion was completely excised. Glomus tumor was confirmed by the pathologist. RESULTS: After the operation, patient didn't complain of his symptoms anymore and there was no evidence of recurrence during 6 months follow-up period. CONCLUSIONS: We report a rare case of glomus tumor arising in subcutaneous layer of forearm with elderly patient.

BACKGROUND AND SIGNIFICANCE: Cytomegalovirus(CMV) is the most common opportunistic viral agent encountered in AIDS and its relation to peripheral neuropathy and rapidly developing lumbosacral polyradiculopathy has been well documentated. CASE: A 30-year-old man with acquired immune deficiency syndrome presented with rapidly progressive paraplegia and voiding difficulty. Electrophysiologic studies revealed a lumbosacral polyradiculopathy with loss of bulbocavernous reflex and CSF examination showed polymorphonuclear pleocytosis with elevated protein level. Also, spinal T1-weighted MRI with gadolinium-DTPA showed enhancement of the pial lining of the conus medullaris, cauda equina, and lumbar nerve roots. Anti CMV titers were elevated in CSF and culture for CMV in both blood and urine was positive. The patient was treated with ganciclovir. CONCLUSION: We report a case of polyradiculopathy related to CMV in a patient with acquired immune deficiency syndrome(AIDS). It seems to be important to differentiate this unique syndrome from other causes of rapidly developing paraplegia syndromes among AIDS patients.

We report a non-obese patient suffering from spastic gait and right leg paresis caused by thoracic spinal cord compression secondary to spinal epidural lipomatosis. Although spinal epidural lipomatosis is most often associated with the administration of exogenous steroid or endogenous Cushing syndrome, obesity also has been reported as a possible cause. However, idiopathic(non-glucocorticoid induced) spinal epidural lipomatosis in non-obese healthy man is an extremely rare disease and dose not have any good explanation for the abnormal fat deposition in spinal epidural space. We recently experienced a patient with idiopathic thoracic epidural lipomatosis in whom MRI and histopathology established the specific diagnosis. With a case report, brief review of the disease including clinical feature, diagnostic procedure and therapeutic considerations is described.

BACKGROUND: As the number of elder patients grows, spinal anesthesia for such patients are increasing significantly. Any effort is needed to use the least anesthetic drug for maintaining the anesthesia while avoiding hazards of cardio-pulmonary complications. METHODS: American Society of Anesthesiologists physical status classification I and II, Forty five elderly patients (> or = 60 years) who received transurethral resection of the prostate or transurethral resection of the bladder tumor were allocated randomly into three treatment groups. The DMT 0.5 group was designed as with dexmedetomidine 0.5 microg/kg while the DMT 1.0 group has a 1 microg/kg intravenous injection over 10 min before anesthetic induction. The Control group was designed to get a normal saline. Each group was compared regarding the maximum sensory block level, extension of anesthesia, degree of motor block, level of sedation, VAS score and complications. RESULTS: There were no significant differences among the 3 treatment groups regarding the maximum level of sensory block and motor block. However, the duration of sensory block was significantly longer in DMT 1.0 group than in the control group (P = 0.045). Both DMT 1.0 group (median = 3, range = 2-6) and DMT 0.5 group (median = 3, range = 1-6) showed a mean value of 3-4 Ramsay sedation score, which resulted in more excessive sedation and significantly greater incidence of bradycardia compared to the control group. No complications such as hypotension, nausea, tremor, and hypoxia were found during this investigation. CONCLUSIONS: In elder patients, the DMT 1.0 group is effective in duration of sensory block and is superior in the aspect of prolonged duration of sensory block compared to the DMT 0.5 group.
