Marjolin's ulcer is a malignant degeneration of cicatrical tissue, especially in chronic burn scar. Since the first description by Jean Nicholas Marjolin(1828), many studies for Marjolin's ulcer have been performed and reported. From 1985 to 1997, we experienced 20 cases in 14 patients diagnosed as Marjolin's ulcer clinically, and we analysed malignant transformation rate, induction period of Marjolin's ulcer and prevention of Marjolin's ulcer, etc. The results are summarized as follows. 1) The sex distribution was predominant in male(64.3%). 2) The most common cause of injury was flame burn(78.6%). 3) The mean age at the time of diagnosis was 45.6 years and the average lag period was 20.6 years. 4) The pathologic types of Marjolin's ulcer were squamous cell carcinoma(57.2%), followed by dyspasia(28.6%), acnthosis and hyperkeratosis(14.2%). 5) The locations of ulcers were frequently on the lower extremity(42.9%), followed by upper extremity(35.7%) and trunk (21.4%). 6) The lymph node involvements were 3 patients out of the 8 patients who were confirmed as squamous cell carcinoma. 7) The modalities of treatment were skin graft (18 cases, 12 patients), myocutaneous flap(1 case, 1 patient), fasciocutaneous flap(1 case, 1 patient).

More than 25,000 products capable of producing chemicals bums are now used in industry, agriculture, military, science, and the home. Cutaneous injury from caustic chemicals is unlike cutaneous thermal injury that tissue destruction continues until its is neutralized or its toxicity is exhausted by reaction with the tissues. Reduction of the time of exposure to the caustic agent and recognition of systemic toxicity are necessary to lessen the severity of insult, reduced morbidity and maximized survivals. During the 9-year period from January 1986 to December 1994, 5,945 burn patients were admitted to the Han Gang Sacred Heart Hospital. Among them, 78 patients were chemicaly burned. In these chemical bum patients, retrospective study was done for the review of following issues; incidence, age and sex, places of accidents, agent, prevalent site, extents of body area fumed, distribution of depth, average hospital days according to extent and depth, complication, mortality rate and management. The result were as follows. 1) The incidence of chemical bums patients was 1.3 % of all admitted bum patients. 2) The prevalent age group was between 20 and 39 years old(67.9%). 3) The ratio of male to female was 9 : 1. 4) The incidence of work-related bums was 71.8%. 5) The most common chemical agent was sulfuric acid(28.2%), followed by sodium hydroxide(17.9%) and hydrochloric acid (12.8%). 6) The most common prevalent site was face and neck(62.2%). 7) Distribution of body area burned between 1 to 10% was 70.4%. 8) The average hospital days according to depth, superficial second degree was 13.4 days, deep second degree was 31 days, and third degree was 83.1 days. 9) The most common complication was scar contracture. 10) Overall mortality rate was 5.1%(4 cases), the cause of death was septic shock and ARDS, and average hospital days was 10 days.

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.

PURPOSE: Supraventricular tachycardia(SVT) is the most frequent symptomatic arrhythmia in children. We performed this study to disover the SVT mechanisms, age at SVT onset, symptoms and ECG findings of SVT and effect of adenosine on SVT. METHODS: We studied 57 patients(male : 30, female : 27, age : 1 day-15.8 years) who had been admitted or transferred due to SVT from January, 1997 to March, 2001. Retrospectively we reviewed their medical records, ECG and electrophysiologic study findings. RESULTS: Of the total 57 patients, the mechanisms of SVT(including atrial flutter) were atrioventricular reentrant tachycardia(AVRT) in 36(63%) patients, atrioventricular node reentrant tachycardia(AVNRT) in 9(16%) patients, ectopic atrial tachycardia(EAT) in 6(11%) patients, multifocal atrial tachycardia(MAT) in 3(5%) patients and atrial flutter(AF) in 3(5%) patients. Of the 12 primary atrial tachycardias(including EAT, MAT and AF), 11 tachycardias began before 1 year of age. The SVT occured before 1 year of age in 21(37%) patients, at 1 to 5 years of age in 7(12 %) patients, at 5 to 10 years of age in 19(33%) patients and after 10 years of age in 10(18%) patients. In symptomatic SVT, the frequent symptoms were palpitation, chest discomfort and chest pain, gastrointestinal symptoms including nausea and abdominal pain, dizziness and dyspnea in decreasing frequency. P wave was discernible in 31(86%) of the 36 AVRT patients and 5(56%) of the 9 AVNRT patients. Adenosine was effective in 19(91%) of 21 AVRT or AVNRT patients. No significant side effect resulted from was occured by rapid bolus intravenous injection of adenosine. CONCLUSION: AVRT was most frequent in pediatric SVT patients. SVT frequently occured before 1 year of age and at 5 to 10 years of age. Primary atrial tachycardia mainly occured before 1 year of age.

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.

Clavicle medial end fracture is rare, and it has not been studied extensively. Although there is debate regarding its treatment methods, because of the complications of conservative treatment, surgical treatment has been considered more than conservative treatment. This study describes a surgical method using double-plate fixation for treatment of clavicle medial end fractures in which plates were used on each anterior and superior border according to the anatomical structure of the clavicle. In addition, we report operative results of three patients treated by double-plate fixation.
