Kawasaki disease or mucocutaneous lymph node syndrome is an acute inflammatory illness of childhood characterized by systemic panvasculitis. It presents with high fever, dramatic changes of the skin and mucous membranes, and lymphadenopathy. Adult-onset Kawasaki disease is rare and reports on coronary involvement in adult are even rarer. Herein, we report a case of adult-onset Kawasaki disease complicated by splenic infarction and development of coronary aneurysm even despite of treatment with intravenous gamma globulin. A 20-year-old man presented with fever, erytheatous rash, induration and desquamation of hands and feet, pulmonary edema and shock due to cardiomyopathy, splenic infarction, bilateral conjunctivitis, jaundice, and cervical lymphadenopathy. After Kawasaki disease was suspected, intravenous gamma globulin (2 g/kg once) and aspirin (6 g/day) were administered. On the 30th hospital day, transesophageal echocardiography showed one coronary aneurysm and coronary angiography showed three aneurysms. Eight months after the first admission, follow-up coronary angiography showed normalization of the previous coronary abnormalities.

PURPOSE: The purpose of this study was to compare the functional abilities of the low bulb obturators with those of high bulb obturators in terms of patients' evaluation. MATERIAL AND METHODS: This study included 11 maxillectomy patients who underwent postoperative prosthodontic rehabilitations. Two obturators of the same design except for different bulb heights, were fabricated for each of the maxillectomy patient. After two months of alternate use, the functions of the obturators were measured by investigating the patients' subjective evaluations in terms of convenience, speech, nasality, leakage, and mastication and identifying their preferred prostheses. Wilcoxon signed rank test was used as a statistical method (P < .05). RESULTS: There were no significant differences in patient evaluations of low and high bulb obturators (P >.05). And patients' preferences varied. CONCLUSION: In extreme situation such as in mouth opening limitation, the use of low bulb obturators can be recommended and result in comparable speech function to that of obturators with high lateral walls.

PURPOSE: The aim of this study was to evaluate the feasibility and safety of our antivenin treatment protocol for patients with Korean Viperidae envenomation. METHODS: We developed an antivenin treatment protocol for Korean Viperidae envenomation, based on previous data, and applied this treatment to the enrolled patients. In brief, antivenin was not used for patients with grade 0. Patients with grade I and II received one vial of antivenin. Those with grade III and IV received two and three vials of antivenin, respectively. Adult patients who visited the emergency department (ED) after receiving a snakebite between July 2008 to August 2010 were included. Follow ups were performed at 24 hours, 7 days, and 28 days after the snakebite. RESULTS: A total of 62 patients were enrolled. At the initial evaluation, 6 patients (9.7%) were grade 0, 47 patients (75.8%) were grade I, and 9 patients (14.5%) were grade II. Upon the follow-up evaluation, 14 patients (29.8%) progressed from grade I to grade II and 2 patients (22.2%) progressed from grade II to III. Coagulopathy developed in 5 patients (8.0%) and rhabdomyolysis in 5 patients (8.0%). Urticaria developed in 2 patients (3.2%) and cellulitis in 3 patients (4.8%) as delayed complications. As an antivenin-related complication, serum sickness developed in only 1 patient (1.6%). There were no severe complications and all clinical and laboratory abnormalities disappeared within 28 days. CONCLUSION: Our antivenin treatment protocol was feasible and safe. To confirm our data, multicenter validation studies are needed.

An insulin-producing cell line, HE, was derived from immortalized human pancreatic p-cells transformed by SV40 DNA, To make serum free medium specific for the cells, it was necessary to select basal medium, hormones, growth factors and coating materials. First of all, human insulin-producing cell line was adapted serially to the culture medium containing minimum required (1%) fetal calf serum (HB-1) from 10% fetal calf serum, The cells had a tendency to attach to the culture dishes coated with collagen or gelatin in the serum-free medium and showed a stronger attachment to collagen than to gelatin, For the basal medium selection, medium containing an equal mixture of RPMI 1640, Dulbecco's modified Eagle's medium, and Ham's F-12 (RDF) was shown to be the most suitable for the cells among 7 differently mixed basal media, The cells exhibited highly positive response to 7 factors including insulin-transferrin-selenium (ITS)complex in the basal medium. In addition, other 16 factors also influenced the cell growth positively, In contrast, 4 factors including aldosterone inhibited the cell growth, Cell growth was enhanced remarkably when the cells were cultured in the serum-free medium supplemented with all the seven positive factors, compared with in RDF serum-free medium. ITS and linoleic acid-BSA were found to be essential for the cell growth. The growth was much higher in the medium containing 6 strong positive factors without either dexamethasone, glucagon, or thyrocalcitonin than in the medium containing all the 7 strong positive factors, It is suggested that the interaction between the individual positive factors must be considered in choosing the factors with which the serum-free medium is supplemented.

PURPOSE: Since 1971, Nitrofen (2,4-dichloro-4`-nitrodiphenyl ether) herbicide has been known to induce variable congenital abnormalities in rats. However, until now there has been no animal model of congenital diaphragmatic hernia (CDH) using this herbicide in Korea. Therefore, CDH in rats using Nitrofen was tried for searching on pathogenesis or using therapeutic modalities of CDH. METHODS: 20 Sprague-Dawley rats ingested Nitrofen as indicated on the 9.5th day of gestation, and after sacrificing on the 21th day of gestation. 243 offspring were harvested for the examination of diaphragmatic herniations. Dissections were made along sites of herniations to confirm the diaphragmatic herniation's site and size, lung/body weight ratio comparison as well as to accomplish microscopic radial saccular counting and evaluation of alveolar septal wall maturations and a comparision was made between the groups. RESULTS: CDH appeared in 149 of 243 offspring. CDH only appeared in the posterior portion of the diaphragm regardless of size or the side of appearance. Left sided CDH was the most common single diaphragmatic anomaly, represented in 112 offspring. Right sided CDH was next, found in 31 offspring, and bilateral CDH was seen in 6 offspring. Left sided CDH was almost always associated with visceral herniations and with pulmonary hypoplasia on the affected side, which was proved in the decreased Lung/Body weight ratio and in decreased radial saccular counts and in increased alveolar septal wall thickness in the affected lungs of CDH. In94 offspring without CDH following exposure to Nitrofen, moderate pulmonary hypo plasia was microscopically observed. CONCLUSION: Initial Rat modeling of congenital diaphragmatic hernia using Nitrofen showed results of herniation and pulmonary hypoplasia of the affected lungs acceptable for further experimental studies on CDH and accompaning pulmonary abnormalities.

PURPOSE: The aim of this study was to investigate a comparison of implant bone bed preparation with Er,Cr:YSGG laser and conventional drills on the relationship between implant stability quotient (ISQ) values and implant insertion variables. MATERIALS AND METHODS: Forty implants were inserted into two different types of pig rib bone. One group was prepared with conventional drills and a total of 20 implants were inserted into type I and type II bone. The other group was prepared with a Er,Cr:YSGG laser and a total of 20 implants were inserted into type I and type II bone. ISQ, maximum insertion torque, angular momentum, and insertion torque energy values were measured. RESULTS: The mean values for variables were significantly higher in type I bone than in type II bone (P < .01). In type I bone, the ISQ values in the drill group were significantly higher than in the laser group (P < .05). In type II bone, the ISQ values in the laser group were significantly higher than in the drill group (P < .01). In both type I and type II bone, the maximum insertion torque, total energy, and total angular momentum values between the drill and laser groups did not differ significantly (P > or = .05). The ISQ values were correlated with maximum insertion torque (P < .01, r = .731), total energy (P < .01, r = .696), and angular momentum (P < .01, r = .696). CONCLUSION: Within the limitations of this study, the effects of bone bed preparation with Er,Cr:YSGG laser on the relationship between implant stability quotient (ISQ) values and implant insertion variables were comparable to those of drilling.

PURPOSE: This is a trial attempting to show that the addition of mycophenolate mofetil (MMF) can reduce toxicity without impacting efficacy in patients undergoing adult living donor liver transplantation (LDLT) who experience adverse events on tacrolimus (Tac). METHODS: Between February 1999 and December 2002, 47 cases of adult LDLT were administered Tac as a first-line immunosuppressive agents. Patients were categorized to a Tac Group (Tac+steroid; n=24) or a Tac/MMF Group (Tac+steroid+MMF; n=23). RESULTS: The actuarial 2-year patient survival rate was similar in the two groups (91.3% vs. 87.0%, P=0.591), and the 2-year rejection-free survival rate was also comparable (95.2% vs. 90.0%, P=0.672). In 14 patients with nephrotoxicity, mean creatinine levels decreased significantly from 1.80+/-0.24 mg/dL to 1.31+/-0.30 (P=0.001) within 3 months of adding of MMF. Of two patients with neurotoxicity, the clinical symptoms of one patient improved after adding MMF. In 7 patients with a lower therapeutic level, the mean Tac doses could be reduced from 6.4+/-4.0 mg at study entry to 2.4+/-1.4 mg 12 months after adding MMF. CONCLUSION: The addition of MMF to Tac is a potent immunosuppressive agent to reduce the Tac-induced toxicity, and which does not increase the risk of allograft rejection in LDLT.
