1.PHYSICAL PROPERTIES OF THE REUSED IPS EMPRESS CERAMIC PART III. STUDY ON THE STAIN RESISTANCE.
The Journal of Korean Academy of Prosthodontics 1999;37(6):776-781
The purpose of this study was to investigate the possibility on recycling of IPS Empress ceramic for the wide use of esthetically pleased IPS-Empress ceramic in clinical prosthodontic treatment. The specimens were made of first, second, and third pressed IPS Empress ceramic and were immersed in 0.05% methylene blue solution for 24hours. The amount of color change before and after stainning was measured with colorimeter(Model Tc-6Fx, Denshoku Co., Tokyo, Japan). The change of E in first pressed ceramic was 18.33 and those in second and third pressed ceramics were 19.33 and 19.93 respectively. Although there was statistical difference among them, the differences were minute and acceptable. From the results of this study, the possibility of recycling of IPS Empress ceramic could be suggested.

The bond failure of resin teeth to denture base resin is one of the failure in prosthodontic treatment. The purpose of this study was to evaluate the bond strength of artificial resin teeth to the denture base resins. Specimens were made with heat curing acrylic resins (Vertex Rs, Lucitone 199) and artificial resin teeth (Tiger, Trubyte biotone, Endura, Orthosit, Trubyte bioform IPN) and the bond strength were measured with testing machine (Zwick, Germany) and the mode of bond failure were observed. The results were as follows; 1. The bond strength of Vertex Rs to artificial resin teeth was the highest in Trubyte biotone, and It was the lowest in Tiger and Trubyte bioform IPN 2. The bond strength of Lucitone 199 to artificial resin teeth were higher in Orthosit and Trubyte bioform IPN than in Tiger and Trubyte biotone. 3. The bond strength of Trubyte biotone to Vertex Rs was higher than to Lucitone 199 and that of the Trubyte bioform IPN to Lucitone 199 was higher than to Vertex Rs. 4. Nearly all bond failures of specimens occured cohesively within the resin teeth.

PURPOSE: It is known that single umbilical artery is frequently associated with gastrointestinal or urogenital anomaly, however, routine renal sonography has been debated in healthy neonate with isolated single umbilical artery. This study is designed to determine the usefulness of routine renal sonography in apparently healthy infants with an isolated single umbilical artery. METHODS: Thirty healthy neonates with a single umbilical artery without a major anomaly from January 1995 to July 2002 were enrolled. The authors investigated the clinical background of babies and their mothers after renal sonography after 72 hours of age. When the abnormalities were found at the first renal sonography, the severity of hydronephrosis and degree of obstruction and renal function were analyzed by follow up renal sonography, voiding cystourethrography(VCUG) and technetium-99m-dimercaptosuccinic acid(DMSA) scan or technetium-99m-mercaptoacetyl-triglycerine (MAG3) scan. RESULTS: Among the 30 healthy patients with isolated single umbilical artery, five patients(16.7%) showed abnormalities on first renal sonography with one major(3.3%) and four(13.4%) minor renal anomaly(minimal or mild hydroneohrosis). One major renal anomaly(severe hydronephrosis) showed severe decreased renal function on MAG3 scan without reflux, and the other four minor regressed spontaneously on follow up study. CONCLUSION: The value of routine early renal sonograpy for detecting renal anomaly in healthy infants with an isolated single umbilical artery remained unclear because most of the anomalies would regress spontaneously in the follow up study.

Primary sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) of the thyroid gland is a very rare disease. We present the clinical and histopathologic findings of a 37-year-old woman recently diagnosed with SMECE of the thyroid gland. The patient, clinically euthyroid, who presented with a neck swelling since last 2 years along. Fine needle aspiration cytology suggested thyroid papillary carcinoma. Total thyroidectomy, central neck dissection and right selective neck dissection were performed. Although SMECE is considered to be a relatively slow growing and non-aggressive tumor, occasional metastasis does occur. We report an additional case of SMECE, with metastasis to regional lymph nodes. Physicians should be aware of extended operation, including total thyroidectomy and/or neck node dissection for metastatic lesion of the neck node. More standardized treatment is likely to evolve in the future.

Diagnosis of Kawasaki disease (KD) is occasionally delayed because it is solely based on clinical symptoms. Previous studies have attempted to identify diagnostic biomarkers for KD. Recently, patients with KD were reported to have elevated serum ferritin levels. We investigated the usefulness of the serum ferritin level as a diagnostic biomarker for distinguishing KD from other acute febrile illnesses. Blood samples were obtained from pediatric patients with KD (N = 77) and those with other acute febrile illnesses (N = 32) between December 2007 and June 2011 for measuring various laboratory parameters, including serum ferritin levels. In patients with KD, laboratory tests were performed at diagnosis and repeated at 2, 14, and 56 days after intravenous immunoglobulin treatment. At the time of diagnosis, serum ferritin levels in patients with KD (188.8 µg/L) were significantly higher than those in patients with other acute febrile illnesses (106.8 µg/L, P = 0.003). The serum ferritin cut-off value of 120.8 µg/L effectively distinguished patients with KD from those with other acute febrile illnesses, with a sensitivity and specificity of 74.5% and 83.3%, respectively. Serum ferritin may be a useful biomarker to distinguish KD from other acute febrile illnesses.
