This case was an acquired aplastic anemia patient who required a major operation for excision of a mediastinal mass. The authors previewed that the coagulation abnormalities would be developed due to major operation. Thus we decided to monitoring the coagulation function using the thromboelastography during the perioperative period and checked the complete blood count, concommitantly. The total blood volume lost during operation was 1800 ml, so we gave him a transfusion of 10 U's of platelet concentrate, 10 U's of pheretic platelet rich plasma and 5 U's of whole blood. The thromboelastography was a good guide that helped us to avoid excessive treatment of the coagulation abnormalities. We concluded that the thromboelastograhy was a reliable and effective monitoring system at the intraoperative coagulation management.

Adenomyosis is a common disease of middle-aged women and adenomyoma is a variety of adenomyosis that formed localized tumor. Cystic degeneration of an adenomyoma is a rare clinical manifestation. A 30-year-old parous woman suffered from severe dysmenorrhea and menorrhagia for about 5 months, was operated under the impression of endometriosis of the pelvis. Following the operation, cystic degeneration of an adenomyoma was found incidentally. The authors experienced a case of adenomyosis that formed cystic tumor of uterus and presented with a pertinent literatures.

BACKGROUND: Antibiotics are used prophylactically in surgery to prevent postoperative infection. However, antibiotics administered in large doses can cause a bleeding diathesis as a result of platelet dysfunction. We wondered whether these antibiotics might impair platelet function by interfering with the initial step of platelet activation: the binding of agonists to their specific receptors on the platelet surface. METHODS: In 30 patients (male 18, women 12) undergoing primary elective knee arthroscopic surgery, the whole blood coagulation system was prospectively evaluated before, and 10 and 40 minutes after administration of 1 g of augmentin. All patients who had abnormal preoperative coagulation profiles or who received anticoagulant or antiplatelet, antibiotics therapy within 7 days prior to surgery were precluded. RESULTS: At 10 minutes after augmentin administration 25 of 30 patients had a significant impairment in all phases of whole blood coagulation as monitored by thromboelastography. In contrast, three of 30 patients had a significantly decreased coagulation time. Two of 30 patients had no significant changes of TEG variables. TEG variables were restored toward baseline in fourty minutes after augmentin administration. CONCLUSIONS: Augmentin can cause a significant but transient change in the viscoelastic properties of blood. Coagulation parameters of the TEG should be measured prior to augmentin administration to prevent and prospect a bleeding diathesis as a result of platelet dysfunction.

Pheochromocytoma stems from the chromaffin cell and mostly is located in the adrenal medulla. It is an important cause of secondary hypertension due to correction of hypertension by a resection of the tumor. Because it produces and secretes catecholamine, it bothers anesthesiologists with excessive hypertension, tachycardia and arrhythmia during the anesthetic period. Therefore, anesthetic management is directed to avoid these conditions. We report a case of bilateral pheochromocytoma successfully managed intraoperatively with an infusion of nicardipine and an intermittent esmolol injection.

BACKGROUND: Epidural anesthesia is becoming an increasingly important aspect of anaesthetic practice because it has many advantages. To achieve the appropriate sedation, various methods have been described. The authors applied the ketamine for this purpose in subanesthetic dose and compared with the midazolam that has been most commonly used for intravenous sedation. METHODS: Fifty-seven adult patients undergoing lower abdominal and extremity surgery who were receiving epidural anesthesia were randomely enrolled into this clinical study. They were allocated to three groups to receive only normal saline (group C), midazolam 0.05 mg/kg (group M) and ketamine 0.5 mg/kg midazolam 0.05 mg/kg (group K) in normal saline 10ml, respectively. Hemodynamic and respiratory measurements were recorded at baseline, 1 minute, 3 minute, 5 minute, 10 minute, 20 minute and 30 minute after sedation. The degree of sedation was assessed by a blinded observer using sedation score. RESULTS: There were no significant differences for hemodynamic and respiratory parameters, but decrements of arterial pressure at 1 minute after sedation were most remarkable in the group M. Sedation was satisfactorily achieved by combination of ketamine and midazolam without significant emergence reaction. CONCLUSIONS: The combination of ketamine and midazolam was judged to be suitable alternative for sedation during epidural anesthesia.

PURPOSE: To describe the abnormal gyral and sulcal patterns obtained by means of three-dimensional (3-D) surface-rendering MR imaging in patients with cerebral cortical disease. MATERIALS AND METHODS: Thirteen patients with cerebral cortical disease [M:F=9:4, aged 8 -55 (median, 26.6) years] underwent 3-D surface-rendering MR imaging. Seven had cortical dysplasia and six showed gyral atropic change, conditions which in all cases were pathologically confirmed. All were the subject of conventional brain MRI imaging studies using the MP-RAGE (magnetization-prepared rapid gradient-echo) sequence, and the resulting 3-D data sets were processed on a commercially available workstation. Abnormal gyral and suleal configurations were reviewed. RESULTS: Abnormal gyral and sulcal patterns were seen in all patients. In eight cases these involved the frontal lobe, in three the parietal lobe, and in two the sylvian fissure. In four patients with cortical dysplasia, conventional MR imaging revealed no cortical abnormality, but 3-D surface-rendering MRI indicated that the configuration and orientation of affected gyri and sulci were abnormal. In nine patients in whom an abnormal gyral pattern was revealed by conventional MRI, 3-D surface imaging confirmed the presence of a thick and enlarged gyrus, or that the configuration of affected gyri was atrophic and abnormal. CONCLUSION: In patients with cerebral cortical disease, 3-D surface-rendering MR imaging detects a high rate of abnormal gyral and sulcal patterns.

Objective: We investigated whether circle of Willis (COW) morphology on 3D time-of-flight (TOF) MR angiography differs between young normal subjects, older normal subjects, and patients with carotid atherosclerotic plaques. Methods: One hundred seventy-seven subjects were grouped according to age into a young group (20 – 40 years; n = 91) and an older group (> 60 years; n = 86). Subjects underwent brain MR examination as part of a health check-up. Fifty-three patients with carotid atherosclerotic plaque were also included for evaluation in this study. COW morphology on 3D TOF MR angiography was analyzed in terms of completeness or incompleteness of the anterior and posterior components of the circle and completeness of the circle. Results: An incomplete pattern of anterior circulation was significantly more common in carotid atherosclerotic plaque patients (20.7%) than normal older subjects (5.5%) (p < 0.01). A complete posterior circulation pattern was more frequent in normal young subjects (46.5%) than in normal older subjects (16.5%) or the patient group (18.9%) (p < 0.01). Of patients with carotid artery stenosis, 18.9% had a bilateral incomplete connection and were significantly more likely to have an incomplete pattern than normal young (2.3%) or normal older subjects (2.2%) (p < 0.001). Conclusion: Young, healthy subjects were significantly more likely to have a complete pattern of posterior circulation than older subjects. Patients with carotid atherosclerotic plaques were significantly more likely to have incomplete anterior circulation and an incomplete circle than young, normal subjects.

Eosinophilic cholecystitis is a rare disease characterized by transmural leukocyte infiltration composed of more than 90% eosinophils. Eosinophilic cholecystitis is clinically indistinguishable from ordinary cholecystitis, and as a rule it leads to cholecystectomy. We report a case of idiopathic eosinophilic cholecystitis treated with steroids. A 75-year-old woman presented with a classic history of acute cholecystitis and a peripheral eosinophilia of 41.8%. There was no evidence of allergy or parasitic infestation. An abdominal ultrasonography and computed tomography (CT) scan showed an edematous, thickened gallbladder wall, but no gallstones. There was no evidence of eosinophilic infiltration in other organs. Cholecystectomy was not performed because the patient refused surgical management. However, fever, abdominal pain, and peripheral eosinophilia persisted despite antibiotic and conservative therapy. Therefore, we attempted treatment with prednisolone. A week later, the symptoms disappeared and the peripheral eosinophilia normalized.
