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).

The patients of developmental dislocation of the hip(DDH) are almost found after walking age because of early diagnosis of DDH in younger children is not easy. A controversy still exists as to the relative value of closed and operative management in the treatment of a child who has reached walking age. This study is a report of the results of 16 patients(17 cases) in developmental dislocation of the hip who have visited our hospital at the age of 9 months to 3 years old, and have been followed more than 12 months (12-112 months) on review of plain radiographs and arthrograms. The results were as follows 1. The age at diagnosis was 16.4 months(9-31 months) in average. The methods of treatment were conservative for 8 cases, and operation for 4 cases and secondary operation for 5 cases who were failed with conservative therapy. 2. By Severin's radiologic grade, the result was good in 4 cases, fair in 3 cases and poor in 1 case in conservative treatment. In operative treatment, fair was in 2 cases and poor in 2 cases. In secondary operative -patients who were failed with conservative therapy, good was in 2 cases, fair in 2 cases and poor in 1 case. 3. Avascular necrosis of femoral head was developed in 3 cases. 4. In the good reduction as determined by arthrogram according to Race and Herring, we can get a favorable result in conservative treatment, and in the poor reduction as determined by arthrogram, the better

The biocompatibility of the titanium has been estabilished through various experimental studies such as cell culture toxicity test, pyrogen test, mutagen test and others. In order to confirm biocompatibility after fabrication of titanium and to clarify the difference between the bone reaction after insertion of the lathed titanium rods and the bone reaction after insertion of the finished and polished rods, both rods were implanted into the proximal femur of a rabbit. Histologic reactions in the bone were observed according to the ASTM standards at the intervals of 6 weeks, 12 weeks and 26 weeks after implantation. The result were as follows In 6 weeks after implantation of lathed titanium rods, inflammatory reactions, such as minimal degree infiltration of polymorphonuclear leukocytes and lymphocytes were observed in all cases. This was thought to be caused by surgical trauma. However, inflammatory cell infiltration was not seen after implantation of polished and finished rods in all cases. The cellular infiltration and the histologic reaction of the bone after implantation of lathed group were significantly more pronounced than those after implantation of the finished group. In 12 weekt after implantation of lathed rods, two of four cases revealed a minimal degree of cellular infiliration and histologic reaction seemed to be more pronounced in the lathed group, but they were not significant statistically.

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.

Spinal intramedullary cysticercosis is a rare manifestation of neurocysticercosis and may present as a isolated lesion. We report a case of cervical intramedullary cysticercosis in a 57-year-old man. The patient presented with weakness, numbness of the right upper extremity, and urinary difficulty. Magnetic resonance images demonstrated a round cystic lesion at the C4-5 level. We performed C4-5 laminectomy with total removal of intramedullary cystic lesion. Diagnosis was confirmed by histopathological examination. The patient was given albendazole(15mg/kg/day for 30 days) along with corticosteroid.
