Hurthle cell tumors are an infrequent neoplasm of the thyroid gland in adults. Hurthle cell tumors represent 4. 5% to 10% of all primary thyroid epithelial neoplasms in the foreign literature. It has been known as Hurthle cell tumor since Ewing was the first to use this term in 1928. Tumor occurring in an infant was described by Symmers(1941) and Morrow(1945). The authors experienced a case of congenital Hurthle cell tumor of the thyroid gland in a 2 months old boy. He was admitted to the pediatric surgical department because of a growing mass in the neck since birth. Ultrasonogram showed a huge lobulated homogenous solid mass with medium level echogenicity in the region of the thyroid gland. Subtotal thyroidectomy of right lobe and total thyroidectomy of left lobe were done. The specimen measures 2x3x1.5 cm and 7x3x3 cm, respectively. It was an encapsulated, yellow gray firm and solid mass. The cut surface was smooth, glistening and homogenous. Microscopicully, the tumor was composed of tightly packed regular follicles lined by polyhedral, cuboidal, large cells with a granular acidophilic cytoplasms. The nuclei are vesicular, usually only a little bit larger than those of normal thyroid cells.

The transarterial embolization has been widely used to control bleeding. It has a variety of clinical utility; to reduce bleeding on the surgical field, to reduce the size of malignant tumor as a preopearative treatment, to treat arteriovenous malformation or arterial aneurysm as a curative method and to promote life qua' ity of patient with diffuse or multiple hepatocellular carcinoma as a palliative treatment, etc. With the advance of modem technology, various embolic materials have been also developed. IIowever, it has not- been -fully investigated of histopathologic changes of the embolized organs according to the embolic materials used. This study was undertaken to investigate the histopathologic changes of embolized renal artery in rabbit by various embolic materials, according to each embolic material and to time passed by after embolization. Of the 5 arteries embolized by ethylene vinyl alcohol copolymer(EVAL), one showed abscess formation in embolized kidney. The other 4 allowed to perform further pathologic study: within a week after embolization there was no any specific change in vessels, however, r,unimal endothelial hypertrophy was observed following 2 weeks of embolization. Of the 8 renal arteries embolized by N-buthyl-2-cyanoacrylate(Histoacryl), 4 showed total occlusion of the main renal arteries as well as renal infarction, which reflects the strong adhesiveness of Histoacryl to vascular wall. The other 4 showed fibrinoid degeneration in vascular wall within a week. However, further change was not observed thereafter. In all the 5 renal arteries embolized by polyvinyl

PURPOSE: Although influenza is regarded as one of the major causes of morbidity and mortality in children with cancer, the actual vaccine coverage remains poor. We conducted evaluation of immunogenicity and safety of influenza vaccine in children with cancer. METHODS: In this study, 25 children with cancer who received influenza vaccine (SK influenza IX vaccine(R)) at the Korea Cancer Center Hospital between October and December 2009 were analyzed. Blood samples of patients were collected twice (at the beginning of this study and at 30th day after vaccination) and their antibody titers were measured using the hemagglutination-inhibition (HI) assay. Immunogenicity of the influenza vaccine was assessed by seroprotection rate on days 0 and 30, seroconversion rate on day 30, and mean fold increase (MFI) of geometric mean titer (GMT) of HI between days 0 and 30. RESULTS: Any of the subjects in our study did not experienced serious adverse events after influenza vaccination. Seroprotection rates were 68% for H1N1, 40% for H3N2, and 36% for B. Seroconversion rates were 12% for H1N1, 16% for H3N2, and 20% for B. MFIs were 0.9 for H1N1, 1.2 for H3N2, and 1.8 for B. CONCLUSION: In the study, we found a limited protective immune response to influenza vaccine, among subjects with cancer. However, some subjects showed seroconversion, and there were no severe adverse events among all subjects, supporting the recommendation of annual influenza vaccination in children with cancer.

Many Oriental women have prominent mandibular angle and short chin, in other words, 'squared' mandibular face or 'boxy' face. That kind of face is considered to be unattractive and causes big cosmetic problems for those who want to have an ovoid or almond shaped face. A squared mandibular face often needs to be corrected by operative procedure. A reduction mandibular angleplasty by bony angle resection is one of the operative procedures, but it is not always an adequate method. The successful correction of squared mandibular face can be accomplished by horizontal facial reduction and/or vertical facial lengthening procedure. From March 1996 to March 2000, We had operated 117 patients. The patients were divided into 3 groups. Group I had prominent mandibular angle and/or massetric hypertrophy. Patients in this group were operated by reduction angleplasty with/without resection of masseter muscle. Group II had prominent mandibular angle, cheek and mandibular body. In this case, we applied reduction angleplasty, contouring of body, resection of buccal fat pad and/or masseter muscle. Group III had prominent mandibular angle with short face. We used methods used for group II and Le Fort I lengthening and genioplasty. Ancillary procedures were forehead lengthening and reduction maloplasty. Successful correction of squared mandibular face could be performed by accurate analysis of facial profile and reduction mandibular angleplasty with proper ancillary procedures for each group. The results were as follows: 1) We obtained successful correction of squared mandibular face with multiple horizontal facial reduction procedures, which reduced anterior and posterior facial plane. 2) In case of short face, we made better mid-low facial balance with vertical facial lengthening and horizontal facial reduction.

Implant-supported overdenture is known as a useful appliance, instead of using the conventional complete denture, for better retention and stability. In this study 4 types of materials such as, gold bar/plastic clip(group AuP), gold bar/metal clip(group AuM), palladium bar/plastic clip(group PdP), and palladium bar/metal clip(group PdM) were used to evaluate the retention forces according to the type of clips and alloys used for bar fabrication, in the Hader bar system. Repeated insertions and removals of overdenture were conducted in each group, and the retention forces were measured and compared the data of each group according to the number of insertion and removal. The obtained results were as follows, 1. In the comparison of retention forces according to type of bar-clip, retention was increased in the order of group AuM, PdM, PdP, AuP, and the retention force of group AuM was significantly increased compared with those of others(p<0.05). 2. In the comparison of retention forces according to the number of insertion, only group PdP showed significant decrease in retention(p<0.05). 3. In the comparison of retention forces according to the type of bar and clip, there was no significant difference in the type of bar, but the retention of plastic clip was significantly higher than that of metal clip when Au bar was used(p<0.05). 4. In the observation of the bar surface, group AuM using Au bar and metal clip showed the most scratches among bar groups.

For the improvement of denture fitness of changed residual ridge, denture liner can be used. Denture liner should be very stable physically in various environments of the mouth as well as be bonded strongly with denture resin. In this study, the specimens bonded with four kinds of soft denture liner and three kinds of hard denture liner were used to test the physical properties of the liners. All experimental groups were stored in 37+/-1degrees C distilled water for 24hours, followed by thermocycling between 15degrees C and 45degrees C with 15 second dwell time. 1000, 2000, 3000 cycles of thermocycling were excuted and physical properties were measured by Instron Universal Testing Machine. The obtained results were as follows: 1. In tensile bond test of soft liners, it was shown that both of Molloplast-B(R) specimens before and after thermocycling had the highest tensile strength, and in case of hard liners, Dura-liner II(R)speimen had the highest tensile strength before and after thermocycling. Depending on thermocycling, Soft-Relining(R), Denture-Relining(R),Molloplast-B(R), Coe-soft(R) and Kooliner(R) specimen showed significant difference(p<0.05). 2. In strain test of soft liners, it was shown that Molloplast-B(R) specimen before thermocycling and the Coe-soft(R) after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) speimen before and after thermocycling had the highest result. Depending on thermocycling. Denture-Relinig(R). Molloplast-B(R) and Dura-Lner II(R) specimen showed significant difference(p<0.05). 3. In Maximum distance test of soft liners, the Molloplast-B(R) specimen before thermocycling and the Coe-soft(R) after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) specimen before and after thermocycling showed highest results. Depending on thermocycling, Denture-Relining(R), Molloplast-B(R) specimens showed significant difference(p<0.05). 4.In elasticity test of soft liners , the Molloplast-B(R) specimen before and after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) specimen before thermocycling and the Tokuso-Rebase (R) after thermocycling showed highest results. Depending on thermocycling, Soft-Relining(R) , Molloplast-B(R) specimens showed significant difference(p<0.05).
