The present study was performed to evaluate the effect of Tetracycline-HCl on the change of implant surface microstructure according to application time. Implants with thermal dual acid etched surface were utilized. Implant surface was rubbed with 50mg/ml Tetracycline-HCl solution and sterilized saline for 0.5min, 1min, 1.5min, 2min, 2.5min and 3min. respectively in the test group. Then, specimens were processed for scanning electron microscopic observation and measured surface roughness by optical interferometer. The results of this study were as follows. 1. The thermal dual acid etched surfaces showed many small peaks and valleys distributed overall surface. 2. The surface conditioning with Tetracycline-HCl and saline didn't influence on its micromorphology. In conclusion, the implant with thermal dual acid etched surface has a protective micromorphology from the detoxification with 50mg/ml Tetracycline-HCl and a scrubbing with cotton pellet. Therefore, the detoxification with 50mg/ml Tetracycline-HCl is an effective method for peri-implantitis in case implants with thermal dual acid etched surface.
Peri-Implantitis

Mechanical and chemical methods are the two ways to treat the implant surfaces. By using mechanical method, it is difficult to eliminate bacteria and by-products from the rough implant surface and it can also cause the structural change to the implant surface. Therefore, chemical method is widely used in order to preserve and detoxicate the implant surface more effectively. The purpose of this study is to evaluate the effect of tetracylcline-hydrochloride(TC-HCl) on the change of implant surface microstructure according to application time. Implants with pure titanium machined surface, SLA surface and porous surface were used in this study. Implant surface was rubbed with sponge soaked in 50mg/ml TC-HCl solution for 1/2 min., 1 min., 1 1/2 min., 2 min., and 2 1/2min. respectively in the test group and with no treatment in the control group. Then, specimens were processed for scanning electron microscopic observation. 1. Both test and control group showed a few shallow grooves and ridges in pure titanium machined surface implants. There were not significant differences between two groups. 2. In the SLA surfaces, the control specimen showed that the macro roughness was achieved by large-grit sandblasting. Subsequently, the acid-etching process created the micro roughness, which thus was superimposed on the macro roughness. Irrespective of the application time of 50mg/ml TC-HCl solution, in general, test specimens were similar to control. 3. In the porous surfaces, the control specimen showed spherical particles of titanium alloy and its surface have a few shallow ridges. The roughness of surfaces conditioned with tetracycline-HCl was lessened and seen crater-like irregular surfaces relative to the application time. In conclusion, pure titanium machined surfaces and SLA surfaces weren't changed irrespective of the application time of tetracycline-HCl solution. But the porous surfaces conditioned with tetracycline-HCl solution began to be slightly changed from 2 min. This results are expected to be applied to the regenerative procedures for peri-implantitis treatment.

PURPOSE: One of the main objectives of periodontal reconstructive surgery is the coverage of exposed roots that occur due to gingival recession. and Aestheic concerns are usually the reason to perform root coverage procedure. This case report was performed to evaluate the effect of root coverage using subepithelial connective tissue graft(SCTG) on Miller's Class I marginal tissue recession. MATERIALS AND METHODS: One patient, with two Miller's class I marginal tissue recession on both maxiallay canines, was treated with root coverage using SCTG (modified Nelson's technique). At baseline, the following measurements were recorded: 1) recession depth; 2) width of keratinized giniga. At 9, 10 months post-surgery, all clinical measurements were repeated. RESULT: 1) The mean root coverage from baseline to 9, 10 months post-surgery was 92.3%. 2) The mean recession depth decreased from 6.5 mm to 0.5 mm. 3) The mean width of keratinized gingiva increased from 1.25 mm to 3.5 mm. CONCLUSION: Within the above results, root coverage using SCTG is an effective procedure to cover Miller's class I marginal tissue recession defect. Also, patient with aesthetic concern could be satisfied with this result.

The present study was performed to evaluate the effect of Tetracycline-HCl on the change of implant surface microstructure according to application time. Anodic oxidation surface were utilized. Implant surface was rubbed with 50mg/ml Tetracycline-HCl solution for 1/2min., 1min., 1 1/2min., 2min., 2 1/2min. and 3min. respectively in the test group. Then, specimens were processed for Ra Value test and scanning electron microscopic observation. The results of this study were as follows. 1. The anodic oxidation surface roughness tests don't show significant difference on conditioning with saline and Tetracycline-HCl. 2. The anodic oxidized surfaces showed the craterous structures. The surface conditioning with Tetracycline-HCl didn't influence on its micro-morphology. In conclusion, Anodic oxidation implant surface is stable to detoxificate with 50mg/ml Tetracycline-HCl of implant surface.

Umbilical anomalies arie from fetal structures such as the omphalomesenteric duct (OMD) or urachus, or from the failure to closure the umbilical fascial ring. The persistence of OMD may lead to several anomalies including umbilical sinus, umbilical cyst, Meckel's diverticulum, or patent OMD (POMD). The clinical signs are local swelling, redness, inflammation, umbilical discharge, and bleeding. The passage of the intestinal contents, through the umbilicus i.e., meconeum or gas, implies a fistula to some part of the intestine. A patent omphalomesenteric duct (OMD) is usually associated with the ileum, but rarely with the cecum or appendix. There have only been eight reports of a neonatal appendicoumbilical fistula. Here the authors report a rare and interesting example of an umbilico-appendiceal fistula, and discuss its etiology and treatment.

A 51-year-old male patient was referred for a sudden out-of-hospital cardiac arrest. Upon arrival, he was conscious and had no chest pain complaints. There was no abnormality in initial electrocardiographic and echocardiographic examinations. However, episodes of recurrent ventricular fibrillation (VF) were documented on rhythm monitoring. Each VF episode was triggered by an isolated monomorphic ventricular premature complex (VPC). Suspecting idiopathic VF, emergency radiofrequency catheter ablation was planned for the VPCs. However, when coronary angiography was performed to exclude silent ischemia, the results showed a total occlusion of the right coronary artery posterolateral branch, which is thought to supply the left ventricular inferior and septal wall. After successful reperfusion, VF episodes and the triggering VPCs disappeared. We are documenting this case to emphasize the potential for silent myocardial infarction to cause out-of-hospital sudden cardiac arrest even in a patient without any symptom or sign of acute coronary syndrome.

BACKGROUND: Little Is known about the compared efficiency of different third generation enzyme-linked immunosorbent assays (ELISA) fort the detection of anti-HCV. We examine the relative sensitivity and specificity of three third-generation anti-HCV assays, and results of discrepant samples among the anti-HCV ELISA are compared with data of a third-generation recombinant immunoblot assay and reverse transcription polymerase chain reaction (RT-PCR) . METHODS:A total of 167 samples (61 positive and 106 negative), screened by a second-generation IMx(R) anti-HCV assay (Abbott 2.0; Abbott Laboratories, USA), weve tested with Innotest HCV 3.0(R) (Green Cross, Korea), LG HCD 3.0(R) (LG, Korea) and DONG-A HCV 3.0(R) (Dong-4, Korea). The discrepant specimens among the 4 anti-HCV ELISA were tested by LG HCD Confirm(R) (LG, Korea) and RT-PCR. RESULTS: The concordance rates of all 4 ansi-HCV ELISA were 80.2% (134/167) and 92.2% (154/167), respectively. The 28 and 31 of 33 specimens showing discrepancy among 4 anti-HCV ELISA were tested with LG HCD Confirm and RT-PCR, respectively. Serum HCV RNA was positive in 2 of 2 reactive and in 6 of 26 nonreactive on LG HCD Confirm. The sensitivity, specificity, positive predictive value, negative predictive value and concordance rate of 4 anti-HCV ELISA were 97.7%, 85.2%, 70.0%, 99.0% and 88.5% (Abbott 2.0) ; 81.4%, 96.7%, 89.7%, 93.7% and 92 7% (Innotest 3.0), 81.4%, 98.4%, 94.6%, 93.8% and 93.9% (LG 3.0), 86.0%, 95.7%, 88.1%, 95.1% and 93.3% (DONG-A 3.0), respectively. CONCLUSIONS: These data indicate that the sensitivity and specificity of 3 third-generation anti-HCV ELISA are comparable, and that these reagents demonstrate improved specificity compared to the second-generation ELISA.

Although brain metastasis of renal cell carcinoma is a major cause of death in Von Hippel-Lindau disease(VHL), it is not easy to distinguish local recurrence of hemangioblastoma from distant metastasis. In addition, heman-gioblastoma has several characteristics suitable for recipient of "tumor-to-tumor metastasis". Authors report a case of Von Hippel-Lindau disease that had metastases of renal cell carcinomas.

PURPOSE: Bezoars are the uncommon result of ingestion of poorly digestible or indigestible substances. It is defined as retained concretions of animal or vegetable material in the gastrointestinal tract. The aim of this study was to review and analyze in these cases with reviewing literature. METHODS: The medical records of 12 cases, treated between May 1999 and April 2009, were reviewed. The clinical characteristics, as well as the diagnostic evaluations and results of medical and surgical treatment, were also analyzed retrospectively. RESULTS: Of the 12 cases, 6 men and 6 women, the bezoars were in the stomach, jejunum and ileum or in both stomach and jejunum in 1, 2, 7 and 2 cases, respectively. 4 patients (33.3%) had a history of gastric or duodenal ulcer following previously received gastric surgery such as subtotal gastrectomy or truncal vagotomy with pyloroplasty. In 3 cases, the bezoars were found in operative field under the impression of intestinal obstruction due to adhesive ileus, which could not be found by preoperative radiologic evaluation. Among the 12 cases, 11 cases were successfully treated by operative and endoscopic removal, but 1 case expired due to sepsis. CONCLUSION: A bezoar occurs mainly in patients who have previously undergone a gastric operation. Surgeons should keep in mind the possibility of bezoars in patients presenting an intestinal obstruction following a past gastric operation. The principle of treatment for bezoars used to be surgery, but recently gastric bezoars are often treated by gastrofiberscopy.
