Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

BACKGROUND: To assess the incidence of venous thromboembolism (VTE) following shoulder surgery and to evaluate the role of postoperative duplex ultrasonography. METHODS: The study comprised a total of 224 patients who underwent shoulder surgery, including 180 shoulder arthroscopic surgeries, 28 shoulder arthroplasties, and 16 plate fixations for proximal humerus fracture between January 2014 and December 2014. The mean age of patients was 59.0 years, and there were 81 men and 143 women. Clinical data, including body mass index, blood tests, metabolic work-up for liver and renal function, previous, and present medical history, were evaluated. Duplex ultrasonography in the operative arm was performed on 2 to 4 days after surgery. RESULTS: The overall incidence of VTE following shoulder surgery was 0.45% (1/224). One patient with open reduction and plate fixation for proximal humerus fracture had asymptomatic deep vein thrombosis that showed complete remission after anticoagulant medication during a 2-month period. Four patients had asymptomatic superficial cephalic vein thrombosis and complete remission without any treatment. There was no case of pulmonary embolism. CONCLUSIONS: The incidence of VTE following shoulder surgery was extremely low in Asians. Duplex ultrasonography may be not considered a routine follow-up of shoulder surgery and can be selectively performed in high-risk or symptomatic patients for VTE.

BACKGROUND: The induced hypotension was used to decrease blood loss, thereby decreasing the need for blood transfusion and/or improving operating conditions at the surgical site. It was hypothesized that SNP-induced hypotension with fixed concomitant esmolol infusion(75 ug/kg/min) might prevent side effects such as reflex tachycardia and reduce SNP dose requirement during SNP-induced hypotension. METHOD: The concomitant infusion of 75 ug/kg/min esmolol was used to potentiate hypotension(30% reduction of mean arterial blood pressure) induced with sodium nitroprusside in six dog during halothane(lvo1%)-N2O(50%)-O2(50%) anesthesia. Mean arterial blood pressure, heart rate, cardiac output, mean pulmonary arterial blood pressure, central venous pressure, arterial blood gas analysis, and mixed venous oxygen saturation were measured and systemic vascular resistance was calculated in the each periods. RESULT: The results run as follows; 1) Compared to SNP-induced hypotension, there was significant reduction in SNP dose requirement to maintain a 30% reduction of mean arterial pressure at the concomitant infusion of 75 ug/kg/min esmolol. 2) There were significant reduction in heart rate, mixed venous oxygen saturation and cardiac output, but significant increase in systemic vascular resistance and mean pulmonary arterial pressure at the coneomitant infusion of 75 ug/kg/min esmolol. 3) No rebound hypertension was observed at 30 minute after SNP and esmolol infusions were simultaneously discontinued. CONCLUSION: The result of present study suggests that esmolol infusion is a safe and effective pharmacologic means of potentiating SNP-induced hypotension during halothane-N2O-O2 anesthesia. Probably esmolol may act by counteracting side effects such as acute tolerance during SNP-induced hypotension.

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.

BACKGROUND AND OBJECTIVES: The objective of this study was to evaluate improvement in hearing and changes in the tympanogram according to the types of mastoid pneumatization and the mucosal condition of the Eustachian tube orifice after performing tympanoplasty type 1. MATERIALS AND METHODS: Among the patients with chronic otitis media who had received tympanoplasty type 1 at Asan Medical Center from June 1990 to March 1997, sixty five patients were evaluated with pure tone audiometry and tympanometry for a short-term (<6 months) and long-term (>1 year) follow-up period. RESULTS: Greater improvement in hearing was shown in patients with tympanogram type A as compared to the patients with type B and C in both short-term and long-term follow-ups. Patients who showed normal mastoid pneumatization were found to have type A tympanogram more frequently than patients who showed abnormal mastoid pneumatization. However, the degree of postoperative hearing improvement did not depend on the types of mastoid pneumatization. Mucosal condition of the Eustachian tube orifice had some influence on the outcome of postoperative tympanogram and hearing. Greater improvement in the hearing levels were observed more frequently in the normal mucosa. CONCLUSION: Postoperative improvement in hearing was closely related to the postoperative change in the tympanogram. Postoperative hearing results and tympanograms were mainly influenced by the mucosal condition of the Eustachian tube orifice. Relatively greater improvement in hearing was observed in the long-term follow-up compared to the short-term follow-up. However, in order to reach any conclusion on this matter, a longer follow-up period and closer observation would be required.

BACKGROUNDS: Temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) is not always intractable to antiepileptic drugs (AEDs). To identify the responsiveness to AEDs and related clinical factors in TLE-HS, we performed this study. METHODS: Consecutive 100 (51 men, mean age=30.2+/-6.6, age range=19-50) patients with TLE-HS were divided into two groups by their responsiveness to AEDs. Intractable TLE-HS was defined if they had any seizures for the preceding year with at least two AEDs. Clinical factors were analyzed to find the association of the responsiveness to AEDs. RESULTS: Intractable TLE-HS was found in 68% of patients. The younger age of onset (12+/-4 vs. 31+/-8 years, p<0.0001), longer duration of epilepsy (17+/-6 vs. 2+/-1 years, p<0.0001), more than five tonic-clonic seizures (GTCs) with secondary generalization (29.4 vs. 6.3%, p=0.0009) and bilateral epileptiform abnormalities on EEG (30.9 vs 6.3%, p=0.0054) were significantly correlated with the intractable TLE-HS. According to multiple logistic regression analysis, bilateral epileptiform abnormalities on EEG (adjusted OR=9.4, 95% CI: 1.98~44.76) and more than five GTC (adjusted OR=7.7, 95% CI: 1.60~33.39) were independently related with poor responsiveness to AEDs in TLE-HS. CONCLUSIONS: The presence of hippocampal sclerosis does not necessarily mean intractability to AEDs. The clinical variables related with the poor response to ADEs in TLE-HS are more than five GTCs and bilateral epileptiform abnormalities on EEG.
