Aneurysmal bone cyst uncommonly involves the pubic bone and tends to grow eccentrically and thin out overlying cortex. In the following case report, a 19-year-old male patient visited out hospital, because of dull pain in his left groin. He was diagnosed as aneurysmal bone cyst originated from the superior pubic ramus by CT guided needle biopsy. Transcatheter arterial embolization was effective in the treatment of this lesion such as complete consolidation after the procedure. At present, 2 years follow-up, no problem was noted at weight bearing as well as hip function or recurrence.

The main goal of spinal surgery using implant is a rigid fixation to provide the stability until solid fusion will occur. Recently, various implant fixation devices have been introduced and transpedicular screw fixation is the usual method. In the past, we obtained the implant-related complications like screw failure and rod breakage after using the modified Harrington rod. However, we obtained good results after follow up over one year using TSRH instrument. We experienced spinal surgery using TSRH instrument in 42 cases since 1991 and followed from one year to 28 months with average 16 months. We analyzed the 28 cases and evaluated the implant-related problems. The results were as follows: 1. Among 28 patients, 10 patients were operated due to fracture and 9 patients operated due to spinal stenosis. 2. The male patients were 16 cases and the female were 12 cases. 3. The TSRH instruments provided the rigid fixation with three points clamping mechanism. 4. The cross-linking plate of TSRH was found to increase stiffness and strength. 5. There were no case of screw breakage. 6. In functional results by Kirkaldy-Willis; foriteria the excellent cases were 15, and the good were 2 cases.

Doxorubicin has characteristic chemomyectomy effect of the eyelid without disturbing other eyelid structures, but the major side effect of doxorubicin is the potential for eyelid skin injury as a result of the drug's toxicity in both animal and clinical studies. Verapamil may be used to reduce the dose of doxorubicin and the number of injections that would amplify the toxic effects of doxorubicin. This study was performed to determine whether there is an increase in the toxic effect of the doxorubicin as a result of verapamil pretreatment of the muscle. After 0.5mg, 1.0mg, and 2.0mg doxorubicin was injected in lower eyelids of each group, and equal dose of doxorubicin was injected fo11owing 1.0mg of verapamil injection in lower eyelid of each group, muscle cell loss were measured by light microscopy and side effect was observed. In verapamil and doxorubicin injection group, there was significant differences in the amount of preseptal muscle and even in the pretarsal muscle than the doxorubicin injection group in all doxorubicin doses. Verapamil, injected with a range of doses of doxorubicin, caused suhstantia11y increased muscle loss in the eyelid, compared with injection of doxorubicin alone. Skin ulceration, entropion or ectropion were not visible. Clinically, verapamil cotreatment might be useful to decrease the dose of doxorubicin injected and/or the total number of injections.

Primary aldosteronism is present in approximately 1% of unselectd hypertensive patients. Adrenal adenoma is a known as one of the surgically curable form of the hypertension. Hypertension is one of the contributing factors for the development of aortic dissection. Cincurrence of aortic dissection in patient with primary aldosteronism is extemely rare. Only one case wasconfirmed by autopsy and reported in the world literature. We report a case of DeBakey type 3 anortic aneursm in a 49-year old hypertensive female patient with primary aldosteronism due to left adrenal adenoma. She underwent left adrenalectomy uneventfully after stabilization of her blood pressure with maximal medical management including nitroprusside, aldactone, enalapril and inderal.

OBJECTIVES: The stress response involves the activation of the hypothalamic-pituitary-adrenal(HPA) axis and the sympathetic nervous system. Corticosteroids have been clearly demonstrated to cause anti-inflammatory and/or immnosuppressive effects in man including granulocytosis in part by decreasing migration into tissue, especially damaged tissues(myocardium), and circulating relative lymphocytopenia. To test whether automated measurements of the the increased serum cortisol-induced hematologic changes in the leukocyte differential significance or not in the initial differential diagnosis of acute myocardial infarction in acute chest pain syndromes. METHODS: 101 consecutive patients with myocardial infarction or myocardial ischemia presenting to the emergency room of Seoul Adventist Hospital with acute chest pain from January 1993 to August 1995(Retrospective group) and from December 1995 to March patients compatible with exclusion criteria in myocardial infarction were excluded. We measured automated leukocyte differential and serial CK-MB level in both groups, and the intial serum cortisol levels in prospective infarction group. RESULTS: 1) Total leukocyte and granulocyte counts were increased in acute myocardial infarction(p<0.01). 2) In acute myocardial infarction group, lymphocyte counts were slightly increased(p<0.05), but relative lymphocytes percentage more significantly decreased(p<0.01). 3) Serum cortisol levels are significantly raised early in the course of the acute myocardial infarction and prior to the elevation of the specific cardiac enzymes on the basis of analytic results of prospective infarction group. 4) Cortisol-induced changes in leukocyte differential were noted with time passes into reverse approximately 4 days later in our study. 5) The leukocyte differential does not shows significant changes in the retrospective myocardial ischemia group, so we arrive in careful conclusion that serum cortisol level seems does not increase. 6) No sexual differences were noted in leukocyte differential. CONCLUSIONS: The serum cortisol level and cortisol-induced leukocyte differential are helpful for initial differential diagnosis of acute myocardial infarction in acute chest pain sysdrome.

BACKGROUND: Among various measures to prevent deep venous thrombosis (DVT) in surgical patients, intermittent pneumatic compression of the legs is known to be effective without increasing the risk of bleeding. In this study, the coagulation/ fibrinolysis profile in patients undergoing gastrectomy with SCD Response Compression System, which detects individual venous refill time, was compared to that with elastic stocking using thromboelastography (TEG). METHODS: Fifty-eight ASA class I-II patients undergoing gastrectomy were randomized into two groups. Patients in ES group (n = 29) were treated with elastic stocking and patients in SCD group (n = 29) were treated with SCD Response Compression System. TEG analysis and traditional coagulation tests were performed on arrival in the operating room, after surgery in the postanesthetic care unit and on the morning of postoperative day 1. RESULTS: There was no significant difference in laboratory data between the two groups. Laboratory data at all time points were within normal limit in all patients. There was no significant difference in TEG data between the two groups. No evidence of a postoperative clinical coagulopathy (DVT or pulmonary embolism) was observed on routine history and physical examinations in any patient during hospitalization. CONCLUSIONS: The effectiveness of SCD Response Compression System in patients undergoing major abdominal surgery on coagulation/fibrinolysis system was similar to that of elastic stocking during perioperative period.

BACKGROUND: Complex regional pain syndrome type I (CRPS-I) is a clinical syndrome that is poorly understood and difficult to treat. Reactive oxygen species (ROS) and inflammatory responses may contribute to the development of CRPS-I. This study evaluated the effect of N-acetyl-cysteine (NAC) on both mechanical and cold allodynia in a rat CRPS-I model. METHODS: Male adult SD rats were used for the CRPS-I model that was produced following prolonged hindpaw ischemia/reperfusion. The rats were divided into 3 groups, Group O (-) (n = 8): rats without a tourniquet; Group O (+) (n = 8): rats received ischemic injury with a tourniquet on the hindpaw and they were reperfused 3 hours after the tourniquet application; and Group ON (+) (n = 8): rats received ischemic injury with a tourniquet ring on the hindpaw and they were reperfused 3 hours after the tourniquet application and they received intraperitoneal N-cetyl-ysteine (500 mg/kg) injection just after the tourniquet application and at 1 day and 2 days after the reperfusion. RESULTS: In the Group O (+), mechanical (von Frey hair) and cold (acetone exposure) allodynia were evident in the affected hindpaw as early as 1 day after reperfusion; this was extended for 2 weeks and it spread to the uninjured contralateral hindpaw. In the Group ON (+), the mechanical and cold allodynia were attenuated compared to those rats of Group O (+). CONCLUSIONS: NAC, a free radical scavenger, was able to reduce mechanical and cold allodynia in this model, and the generation of ROS is partly responsible for CRPS-I.

BACKGROUND: There is no effective treatment modality for caustic agent ingestion. Dilution and neutralization are prohibited because of the risk of secondary thermal injury. This experiment is designed to evaluate the amount of dilution and neutralization heat and to gauge the applicability of dilution and neutralization therapy using cold solutions to suppress the peak temperature. METHODS: This is an in-vitro chemical experiment. HCl, CH3COOH, NaOH, and NH4OH are selected as representatives of strong and weak acids and strong and weak alkali, respectively. 20degrees C, 11.6M, 5.8M, and 2.9M solutions of each acid and alkali are made and mixed using a magnetic stirrer at a room air temperature of 28degrees C. The peak temperature, the duration above 40degrees C, and the heat amount are measured or calculated. RESULTS: When a 11.6M HCl or NaOH solution is diluted with same amount of water, 32 or 18cal. per mL of HCl or NaOH is produced, respectively. HCl produces a significant peak temperature, but NaOH does not. The lower the concentration, the lower the amount of heat production. 11.6M CH3COOH and NH4OH solutions don't produce dilution heat. 11.6M and 5.8M solutions of all acids and alkali produce destructive neutralization heat. However, 2.9M solutions produce neutralization heat which might be controllable. When a 11.6M HCl or NaOH solution is neutralized with a -10degrees C 2.9 M NaOH or HCl solution, respectively, the peak temperature produced is below 40degrees C and seems to add little thermal damage to viable tissue. CONCLUSION: Dilution and neutralization with a cold solution in cases of strong acid or alkali ingestion is a promising method to avoid thermal injury.
