The purpose of this study was to evaluate the histologic difference that occured after trichloroacetic acid(TCA) chemical peel in an animal model that was pretreated with Tretinoin alone or Tretinoin-based combined pretreatment kit. Eight Hartley white guinea pigs were used in our study. The dorsal skin of the guinea pigs was divided into six equal squares(2x2 cm). Upper two areas of these six were not pretreated, middle two areas were pretreated for 4 weeks with Tretinoin alone and lower two areas were pretreated for 4 weeks with Tretinoin-based combined kit. Each guinea pig underwent chemical peel with 50% TCA. The wounded areas were biopsied at post-peeling 3 weeks and 6 weeks. The histology revealed that those animals pretreated with combined kit healed quicker than the animals pretreated with Tretinoin alone. This study implies that if patients are treated with Tretinoin-based-combined pretreatment kit before undergoing chemical peel, the pretreatment time will be shortened.

2.A case report of the external nose reconstruction using forehead flap and auricular composite grafts.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2005;31(4):350-355
There are various surgical methods for reconstruction of the nasal defect. Among them, there is some difference in the choosing the proper reconstruction method according to defect size and position. When the defect involved the tip, the columella, and the alar, the local flaps may be preferred, because they can provide sufficient amount of tissue. However, the composite grafts from the ear have been effectively used in reconstructions of smaller sized defects of the columella and ala. We excised total external nose because of squamous cell carcinoma on the nasal tip, columella, and nasal septum. We reconstructed the nasal tip, both alae, and columella with forehead flap. After division of the regional flap, we found partial necrosis of the columella and narrowness of the nostril. So, we used chondrocutaneous auricular composite grafts for reconstruction of the columella and both nostrils. We used the file-folder designed auricular composite graft for reconstruction of columella and the wedge shaped ear helical composite grafts for widening of nostrils. 6 months later, there were no significant problems, except some mismatched dark color in the grafted alar tissues. Here, we report a successful reconstruction of large nasal defect using combined two different reconstructive methods.

Osteopoikilosis is an asymptomatic osteosclerotic dysplasia, initially described by Albers-Schönberg and Ledoux-Lebard and associates. This disorder is described as extremely rare. Inherited and sporadic cases of osteopopikilosis have been reported. A Case of familial osteopoikilosis is presented with a brief review of literatures.

The members of the Task Force Team of the Korean Society of Pediatric Emergency Medicine prepared the document to apply for the subspecialty accreditation of pediatric emergency medicine by the Korean Academy of Medical Sciences in spring 2020. Here, we summarize the background and necessity of implementing the subspecialty of pediatric emergency medicine in Korea. The goals of the implementation are as follows: 1) to augment research, 2) to cope with the development of medical technology, 3) to respond to the change in disease patterns, 4) to meet the increasing demand for medical care, and 5) to improve real aspects of the medical delivery system.

We have treated adult acute leukemia 64 patients between January 1990 and October 1991 at the Chungnam National University Hospital. They were examined for the impact of presenting WBC count on the initial course and from them we have chosen twenty patients whose leukocyte count is over one hundred thousands per cubic milimeter. We divided the twenty patients into 4 groups on the base of treatment modalities: conservative therapy only, chemotherapy only, cranial irradiation only, and chemotherapy with cranial irradiation. Early sudden death rate is lower in cranial irradiation with/without chemotherapy groups than the conservative only or chemotherapy only patients. Also the remission rate is high in cranial irradiation with chemotherapy patients. Therefore we suggest that the rapid intervention of cranial irradiation in adult acute leukemia could be helpful in reducing the early sudden death rate and perhaps in increasing the remission rate.

9.Arthroscopic Treatment of Fabella Impingement Syndrome after Total Knee Arthroplasty: A Case Report.

Fabella impingement syndrome after total knee arthroplasty (TKA) is a rare condition. However, the location of the inserted prosthesis and the size of the fabella are considered major causative factors. Thus far, a conventional surgical excision of the impinged fabella is recommended treatment for the impingement. A 72-year-old woman was diagnosed with degenerative arthritis of the knee. She complained of fabella impingement due to an incompletely excised bony spur behind the posterolateral femoral prosthesis after TKA. The fabella and remaining bony spur were removed using an arthroscopic procedure. The impingement has not recurred and the range of motion (ROM) of the knee was improved after a 12 months follow-up. Arthroscopic surgery might be an alternative treatment for fabella impingement after TKA.

In a jaundiced patient, it is important to ascertain as early as possible whether the bile duct is dilated. Ultrasonography, computed tomography & conventional cholangiography are widely accepted methods of determining the size of the extrahepatic bile ducts. But there is a considerable discrepancy among the size of the bile duct as measured from them. So the author analyzed and compared the respective diameters of the bile ducts in Korean normal adults as measured from cadaver, IV cholangiography, ultrasoud and computed tomography. The materials were 45 cases of cadaver, 38 cases of IV cholangiography, 100 cases of ultrasonography & 55 cases of computed tomography. The results were as follows ; 1. The diameters of the bile ducts were 7.58±2.26mm at CHD & 8.04±2.42mm at CBD from cadaver ; 5.38±1.90mm at CHD & 6.58±2.37mm at CBD from IV cholanglography ; 3.24±1.13mm at CHD & 4.71±1.48mm at CBD from ultrasonography ; and 4.56±1.51mm at CHD & 5.87±1.68mm at CBD from computed tomography. 2. The diameter of the bile duct was greatest in cadaver, and then reduced in IV cholangiography, computed tomography and ultrasonography in this orde.r 3. There were no size discrepancy between the diameter of the common hepatic duct and that of the common bile duct. 4. There were no discrepanry of the diameter of the bile duct by sex.
