Lipoma is most common tumor that compromises 4% to 5% of all benign neoplasm, but in oral cavity it is uncommon. In oral cavity, lipoma presents painless, asymptomatic, slow growing, but sometimes it grows to larger size causing deformities, mastication and speech difficulties. While lipoma in commonly affects female patients (68-73%), oral lipoma appears more frequently in male patients. The majority of oral lipoma is seen after the age of forty (uncommon in children). Lipoma of oral cavity and maxillofacial region occurs most commonly in the parotid region, followed by the buccal mucosa, lip, tongue, palate, mouth floor, gingiva in order. A treatment of lesion is surgical excision with recurrence not expected. In this paper we present the case of a patient who has Lipoma in the mouth floor.

Purpose: Simultaneous implantation has been traditionally limited to patients with at least 5 mm of residual bone to ensure that the implant is completely stabilized. This is considered to be one of the most critical factors for primary implant stability and parallelism and, subsequently osseointegration. Recently, improved initial implant stability is provided by advancement of surgical techniques, implant designs and surface treatments. This has led surgeons to extending simultaneous treatment option to patients with below 4 mm of residual bone height, despite the lack of much data. The purpose of this study was to retrospectively evaluate and compare the status of implants which are installed by delayed and simultaneous methods. Material and methods: The subjects were patients(121 patients, 278 implants) who had been operated with sinus lifting from 2003 to 2007 in Sun Dental Hospital. Lateral window approach with autograft and xenograft(1:1 ratio) were carried out for all sinus lifting. 4 types of implant were used. The mean follow up period was 26.3 months(19 - 58 months) in delayed group, and 22.8 months(18 - 43 months) in simultaneous group. Results: The survival rate of implant restoration of this study was 98.2% in delayed group and 91.7% in simultaneous group. In simultaneous group, wide-platform type implants showed 100% survival rate. The total average of marginal bone loss in radiographs was 0.96 ± 0.29 mm in delayed group and 1.02 ± 0.31 mm in simultaneous group. Conclusion: Simultaneous implantation with sinus lifting(below 4mm of residual bone height) could be predictable treatment.

Each country in the world is enforcing the competition law in order to promote competition in their domestic markets. In the early time of the competition law, the extraterritorial application of the law to foreign businesses was not a big issue because the amount of transaction by foreign businesses in the domestic market was not significant. However, with the increase of trade among countries by the rise of multinational enterprises, dependency on foreign trade increased and, as a result, changes in the situation related to the application of the law has become inevitable. That is, business activities that foreign businesses performed in foreign countries may have effects on the domestic market. Thus, led by the U.S., many countries in the world are applying their competition laws to foreign business for fair competition in their domestic market. Recently the Fair Trade Commission in Korea also imposed 8.8 billion won on the international cartel of graphite electrodes in 2002 and 3.4 billion won on the international cartel of vitamin in 2003. However, there was a risk of dispute because no explicit legal ground was provided in the Fair Trade Act for the extraterritorial application of the law and the procedure of service was not clear. Thus the Fair Trade Act in Korea added in the 11th revision (December 31 2004) a new provision that the Korean law can be applied to an act executed abroad if the act has an effect on the domestic market. However, the addition of the new rule does not solve all relevant problems. It is because the meaning, the scope and the limit of the effect mentioned in the provision should be defined. Thus the present study purposed to examine the scope of application of the competition law to foreign businesses based on basic theories on sovereignty, to review theoretical grounds on which and the scope to which the U.S., EU, Germany and Japan apply their competition law, and lastly to investigated the enforcement of the Fair Trade Act upon foreign businesses in Korea focused on decided cases of extraterritorial applications to international cartels in order to understand theoretical background of the new rule of extraterritorial application of the Fair Trade Act and to identify tasks to be considered in the process of extraterritorial application.

Purpose : The sensory radial forearm flap is used to recover the soft tissue defect of hand and foot. The aim of this study is to evaluate the results after sensory reconstruction using sensate radial forearm flaps. Materials and Methods : There were 9 cases of 8 patients (6 males and 2 females). The 7 cases of 6 patients were donated to foot, the 2 cases of 2 patients to hand. At operation, the ages of them ranged from 18 to 63 years (mean: 37.9 years). Sensory evaluation was performed using percentage(%) of responding area to the pinprick test and the static and moving two-point discrimination test (s-2PD and m-2PD). Results : The mean percentage of responding area to the pin prick test was 48.5%. The mean s-2PD and m-2PD of recipient hands were 37.2 mm and 28.8 mm. The mean s-2PD and m-2PD of recipient feet were 46.7 mm and 45.0 mm. The mean s-2PD and m-2PD of controls were 23.5 mm and 19.7 mm. Conclusion : All the recipients were less sensitive than the control, but the recipient hands more sensitive than the recipient feet. Although the small numbers were studied, the results suggested that the recovery of sensation in the innervated flaps was influenced by the recipient nerve. So the donor nerve seems to be selected as more sensitive and more distal nerve of donor site for better outcome.

Purpose : We performed this study in order to analyze the clinical results of functioning gracilis musculocutaneous free flap transplantation for reconstructon of hand function in cases of Volkmann's ischemic contracture and massive soft tissue injury of forearm. Materials and methods : 18 cases were reviewed with 5 yeas of mean follow up period. We evaluated total active motion of the finger joints and wrist, pinch and grip strength. Results : The flap were survived in 17 cases and 1 case was failed due to infection. The sum of active motion of finger joints(TAM) was improved from 0 to $173.8^{\circ}$. The average grip and pinch strength was improved from 0 kg to $2.7{\pm}2.1kg$ and from 0 kg to $2.4{\pm}1.6kg$. Conclusion : The results in most cases were acceptable in relatively long term follow-up. It may be an option for reconstruction of hand function in cases of Volkmann's ischemic contracture and traumatic upper extremity injury.

The calcifying odontogenic cyst(COC) is considered to occupy a position between a cyst and an odontogenic tumor-having charateristics of both. Gorlin and col. described the COC for first time as an own pathological entity in 1962. Clinically, the COC represents 1% of the odontogenic lesion. It is possible to be found from the first decade to the eight decade but is more frequent during the second decade. It affects in same proportion the maxilla and jaw, being the most in tooth-bearing area of the jaw. This case of COC associated with an unerupted tooth which appeared in the right mandible of 22-year-old woman, was reported. This case report is to present a review of the literature relates to this case of COC and its treatment, discuss clinical, radiographic, histological and therapeutic aspects.

Colorectal cancer during pregnancy is extremely rare. The diagnosis is frequently delayed because symptoms may be confused with those of normal pregnancy. In 1S35, Cruvethier reported the first case of colorectal carcinoma complicating pregnancy. Since then, about 200 or more cases were reported in western countries, but no case of these has been reported in Korea. We experienced a 29-year-old pregnant woman concomitantly developed an adenocarcinoma of the right colon with intestinal obstruction at 12 weeks of gestation. We performed right hemicolectomy at 14 weeks of gestation and therapeutic abortion at 17 weeks of gestation. We report a case of colon cancer during pregnancy with a review of the diagnosis and management. (Korean J Gastroenterol 1996; 28:457 - 461)
