Palpation of an abdominal mass in an infant or child presents a challenging problem in diagnosis and treatment. We reviewed the data on 166 patients under age 15 years who admitted to Ped. Dept. of PMC due to palpable abdominal mass in Jan. 1972-July 1977. The results are as follows 1. Of the 57 surgical cases, pathologically confirmed abdominal tumors were 39 cases. Of the 20 retroperitoneal tumors, Wilms tumors were 13 cases, neuroblastomas were 3 cases, polycystic kidney was 1 case, and retroperitoneal teratoma was 1 case. Of the 19 intraperitonel tumors, hepatomas were 3 cases, hepatoblastoma was 1 case, choledocal cysts were 3 cases, mesenteric and omental cysts were 4 cases, malignant lymphomas were 4 cases and ovarian cysts were 3 cases. Other surgical diseases were 2 cases of ascariasis and 2 cases of bezoar. 2. Medical cases were as follows : 35 cases of leukemia, 15 cases of infectious hepatitis, 14 cases of congenital syphilis 7 cases of liver cirrhosis 7 cases of lirerabscesses, 4 cases of miliary Tbc., 3 cases of congenital spherocytosis, 1 case of cryptococosis, I case of osteopetrosis and 1 case of erythroblastosis fetalis. 3. In age distribution, almost all cases(94%) of Wilms tumor and neuroblastoma were under age of 4 and half of medical cases in infancy were congenital syphilis. 4. Of the pathologically confirmed 39 abdominal tumors, 20 cases were retroperitoneal tumor and 19 cases were intraperitoneal tumor. Of the 20 retroperitonel tumor cases, 16 cases were renal origin, 3 cases were adrenal origin, and 1 case was teratoma. Of the 19 intraperitoneal tum orcases, 8 cases were hepatobiliary origin, 3 cases were ovary origin, 4 cases were omental and mesenteric origin and 4 cases were lymphatics origin. 5. Of the 39 abdominal tumor cases, 34 cases (87%) visited the hospital with the chief complaint of palpable abdominal mass. But, of the 94 medical cases, only 16 cases(17%) visited the hospital with the chief complaint of palpable abdominal mass. 6. In some cases presumptive diagnosis on the base of history taking, physical examination, chest X-ray, simple abdominal X-ray. Peripheral blood findings on admission were uncorrect. In 1 case of Wilms tumor, we suspected liver abscess on admission. In 1/3 case of intraperitoneal tumors, we suspected retroperitoneal tumor on admission. We suspected lymphoma on admission in 1 case of ascariasis and 1 case of bezoar. We misdiagnoed 1 case of miliary Tbc. As hepatoma, 1 case of liver cirrhosis as retroperitoneal tumor and 1 case of congenital syphilis as retroperitoneal tumor on admission. 7. In the treatment of malignant abdominal tumor, we tried all possible measures such as surgery, chemotherapy, and radiation therapy. But prognosis of all malignant abdominal tumors were very poor. Only 1 case of Wilms tumor and 1 case of hepatoblastoma were survived at the time of review.

A 7 day old female baby suffered from perinatal asphyxia and trauma at birth. Subsequently, she had a violeceous subcutaneous plaque on back. The clinical setting, the skin manifestation and the histologic findings of the lesion were diagnostic of subcutaneous fat necrosis of the newborn. Histologic findings revealed fat necrosis with infiltration of inflammatory cells, foreign body giant cells and several fat cells contain needle shaped cleft in radial arrangement. Four weeks latter, the skin lesion was healed spontaneously.

It is notoriously difficult to obtain a sound bony union of large segmental bone defects secondary to trauma or following tumor resection, infected nonunion, congenital pseudarthrosis of the tibia, and avascular necrosis of the femoral head with conventional methods. Recent advances in microsurgery have made it possible to provide a continuing circulation of blood in bone grafts so as to ensure viability. With the nutrient blood supply preserved, healing of the graft to the recipient bone is facilitated without the usual replacement of the graft by creeping substitution. Thus, the grafted bone is achieved more rapid stabilization of bone fragments separated by a large defect without sacrificing viability. Thirty nine cases of the free vascularized fibular graft had been performed in the Department of Orthopedic Surgery, Kyung Hee University Hospital during the period of 3 years from October 1978 to December 1981. Of these, ll cases were congenital pseudarthrosis of the tibia, 4 cases were tuberculous spondylitis, 4 cases were infected nonunion, 7 cases were large segmental bone defects secondary to trauma, 9 cases were avascular necrosis of the femoral head and the other was one case. The results were obtained as follows: 1. The advantages of free vascularized living fibular graft are one stage procedure, resistance of torsion and angular stress, union with rapid hypertrophy of the graft, a shorter immobilization period and more rapid incorporation of the graft into the recipient area. 2. Free vascularized fibular graft can be widely used in the field of Orthopedic surgery. 3. The fibula is the bone best suited for reconstruction of a defect in a long bone. 4. In children, distal tibiofibular synostosis must be performed. 5. For prevention of clawing toe, the muscles around the bone is meticulously dissected, 6. Evaluation by selective arteriography and isotopic scanning both before and after operation may be used to assess the viability of the fibula graft.

Adult stem cells are multipotent and self-renewing cells that contain several functions; i) migration and homing potential: stem cells can migrate to injured and inflamed tissues. ii) differentiation potential: stem cells which migrated to injured tissues can be differentiated into multiple cell types for repairing and regenerating the tissues. iii) immunomodulatory properties: stem cells, especially mesenchymal stem cells can suppress immune system such as inflammation. All those characteristics might be useful for the treatment of the digestive tract diseases which are complex and encompass a broad spectrum of different pathogenesis. Preclinical stem cell therapy showed some promising results, especially in liver failure, pancreatitis, sepsis, and inflammatory bowel disease. If we can understand more about the mechanism of stem cell action, stem cell therapy can become a promising alternative treatment for refractory digestive disease in the near future. In this review, we summarized current preclinical experiences in diseases of the digestive tract using stem cells.

In this study the in vitro protective effects of several antioxidant vitamins (vitamin C, alpha-tocopherol, beta-carotene), fruits and vegetables (strawberry, tangerine, orange and 100% orange juice, carrot juice), on the levels of isolated human lymphocyte DNA damage was measured using Comet assay. Comet assay has been used widely to assess the level of the DNA damage in the individual cells. Lymphocytes were pre-treated for 30 minutes with antioxidant vitamins (10, 50, 100, 500 micrometer) or fruits. vegetables (10, 100, 500, 1000 microgram/ml), an4 then oxidatively challenged with 100 micrometer H2O2 for 5 min at 4degrees C. The protective effect of antioxidant vitamins against DNA damage at a concentration of 50 micrometer were 50% in vitamin C, 32% in alpha-tocopherol, whereas, beta-carotene showed a 55% protection at a dose as low as 10micrometer. The inhibitory effects of DNA damage by strawberry, tangerine, orange, orange juices, carrot juices were 50 - 60% with wide ranges of doses. The results of the present study indicate that most the antioxidant vitamins and fruits.vegetables juices produced a significant reduction in oxidative DNA damage.

In Korea, the metallic implant had to be supplied through import channel with many problems. KAIST succeeded in making AISI 316 LVM stainless steel within the criteria of American Society for Testing and Materials. With the animal experiment at preliminary report I, the biocompatibility in the muscle was examined. For biocompatibility test of new material, test in the bone is essential. In this animal experiment using rat tibia, the biocompatibility of the Kirschner wire of KAIST was compared with that of Zimmer. The result was as follows: 1. Tissue reaction of the Kirschner wire of KAIST was minimal to moderate. 2. Corrosion was negligible, and there was no definite difference between the KAIST and Zimmer Kirschner wires. 3. Authors observed the satisfactory biocompatibility of the KAIST Kirschner wite in bone and muscle, and concluded that the Kirschner wire of KAIST can be applied to human body without serious problems.

PURPOSE: Split thickness skin graft is a frequently used reconstructive technique in burn wound, but the ideal dressing material of the donor site is yet to be developed. The donor sites have been managed with various dressing materials. The aim of this study is to compare four different dressing materials for management of the donor site in a prospective trial. METHODS: This study is based on 85 patients who had undergone split thickness skin graft from September 2011 to February 2012. The grafts harvested with a same manner and the donor sites were managed with one of the four dressing materials: Aquacel Ag(R), Mepitel(R), Bactigra(R), Op-Site(R). We compared post-operative pain scale, the time required epithelialization, ease of application, post-operative infection and number of dressings. RESULTS: Aquacel Ag(R) was the more painless dressing materials in post-operative day 1, 4, 7, 10 than Mepitel(R), Bactigra(R), Op-Site(R). Number of dressings was more lower for Aquacel Ag(R) with Mepitel(R). Ease of application was more higher for Aquacel Ag(R) with Mepitel(R). But Aquacel Ag(R) was not earliest epithelialization. The incidence of infection was not low in Aquacel Ag(R). CONCLUSION: Aquacel Ag(R) dressing is better than other dressing materials for split thickness skin graft donor site in the number of dressings, ease of application, post-operative pain.
