Gastrointestinal hemangioma is a relatively uncommon benign vascular tumor that can occur anywhere in the gastrointestinal tract. It is the second most common vascular lesion of the colon and a clinically important entity because of the possibility of massive hemorrhage when complicated. In gross appearance, hemangioma presents variously as a pedunculated, subpedunculated, or flat elevated lesion similar to a submucosal tumor. A typical case of hemangioma is relatively easy to diagnose because the lesion presents as translucent blue-purple vessels under the mucosa. However, it can be difficult to diagnose in some cases, especially if it does not have its usual characteristic color or is covered with normal mucosa. We incidentally found a colonic hemangioma that had the unusual appearance of a pedunculated polypoid lesion with normal mucosa. It was misdiagnosed as a pedunculated polyp with a long, thick neck and treated by using an endoscopic mucosal resection.

STATEMENT OF PROBLEM: The current trend in prosthodontics is the adoption of a conservative approach to preparing dental prostheses by minimizing the amount of sound tooth structure removal during preparation. PURPOSE: The major disadvantage of the adhesion bridge is the inherently poor resistance to dislodgement that its use in areas subjected to high occlusal load is limited. The purpose of this study was to compare the dislodgement resistance of Bio-pin(R), conventional 3-unit and adhesion bridges. MATERIAL AND METHODS: The experimental groups were classified as follows: .Group I : 3-unit bridge cemented using Super-Bond. C&B .Group II : Adhesion bridge cemented using Super-Bond. C&B .Group III : Bio-pin(R) design adhesion bridge without incorporation of Bio-pin(R) (cemented using Super-Bond. C&B) .Group IV-1: Bio-pin(R) retained adhesion bridge incorporating a single Bio-pin(R) (cemented using Super-Bond. C&B) .Group IV-2: Bio-pin(R) retained adhesion bridge incorporating a single Bio-pin(R) (cemented using Panavia. F) .Group V : Bio-pin(R) retained adhesion bridge incorporating two Bio-pins. (cemented using Super-Bond. C&B) RESULTS: The results of this study were as follows: 1. Significant differences in dislodgement resistance of the restorations were found between Group I, Group II and Group III (p<0.05). No significant differences in dislodgement resistance of the restorations were observed between Group I, GroupIV-1 and GroupV. However, there were significant differences in dislodgement resistance between GroupII and the other groups (p<0.05). 2. No significant differences in dislodgement resistance of the restorations were observed between GroupIV-1 and GroupIV-2, both of which utilized a single Bio-pin(R). However, significant differences were observed when GroupIII was compared to either GroupIV-1 or GroupV (p<0.05). 3. No significant differences in dislodgement resistance relative to the type of dental cements used were found. CONCLUSION: From the above results, it is concluded that the dislodgement resistance of Biopin. bridge restorations utilizing a single Bio-pin(R) is similar to that of a conventional 3-unit bridge. The results also suggest that Bio-pin(R) bridge restorations using a single Bio-pin(R) are a viable alternative to the conventional 3-unit bridge when minimal removal of sound tooth structure and fulfillment of both function and esthetic aspects are considered.

BACKGROUND AND OBJECTIVES: The purposes of this study were to provide evidence of any correlation between the endothelial dysfunction and the extent of coronary atherosclerosis, and the relationship between the endothelial function and individual atherosclerosis risk factors in patients with significant coronary artery stenosis. SUBJECTS AND METHODS: The endothelial function was measured by hyperemia induced brachial artery dilation, using high resolution ultrasound, in 284 consecutive patients (mean age 59 years, men: 176) having undergone coronary angiography. The subjects were divided into four groups according to the number of coronary arteries narrowed by more than 50%; 0 (n=88), 1 (n=98), 2 (n=54) and 3 (n=44). The endothelial functions were compared to see if significant coronary artery disease was present, according to the groups and the presence of individual atherosclerosis risk factors. RESULTS: There were no significant differences in the endothelial dysfunction between the narrowed and normal coronary artery groups (4.66+/-2.45% vs. 4.43+/-1.53% p>0.05) or between the four groups. The endothelial function in patients with significant coronary artery stenosis (n=196) was significantly lower when coupled with hypertension (n=84, 2.99+/-2.4% vs. 4.20+/-2.4%, p<0.05), diabetes (n=44, 4.07+/-2.7% vs. 4.84+/-2.5%, p<0.05) and hypercholesterolemia (n=82, 4.26+/-1.9% vs. 4.95+/-2.7%, p<0.05), but not with smoking. CONCLUSION: The endothelial function showed no difference according to the extent of coronary atherosclerosis. Risk factors of atherosclerosis, such as hypertension, diabetes mellitus and hypercholesterolemia, can deteriorate the endothelial function further, even in the patients with significant coronary artery stenosis.

A massive intracoronary thrombus, during percutaneous coronary intervention (PCI), implies a high risk of major adverse cardiac events. We experienced a case of successful PCI, using Percusurge(r), in an acute myocardial infarc-tion patient, with massive intracoronary thrombi. The TIMI 3 coronary flow could not be restored during a primary PCI of the right coronary artery, despite repeated ballooning, intracoronary urokinase injection, parenteral abciximab and heparin. However, successful PCI, with stenting, was performed by aspiration of the large intracoronary thrombi, with the Percusurge(r) system, 5 days after the primacy PCI.

Congenital rubella syndrome is a transplacental fetal infection with rubella virus and shows a wide spectrum of clinical expression from severe malformation to asymptomatic in the neonatal period. For the confirmation of congenital rubella, one of the following laboratory criteria should be present: isolation of rubella virus, demonstration of rubella-specific IgM antibody, or a rubella IgG antibody that persists and fails to drop at a rate of twofold dilution per month. Recently a reverse transcription-nested polymerase chain reaction (RT-nPCR) method for the prenatal diagnosis of rubella virus infection has been used. We experienced a case of congenital rubella in a 15- month old male who had suffered from respiratory difficulty. He had low birth weight. Thrombocytopenia was noticed shortly after his birth. He was transferred to our hospital because persistent respiratory difficulty had been developing since the age of one month. His growth and development were delayed. Physical examination revealed micrognathia, hepatosplenomegly, lymphadenopathy, and petechiae. Laboratory examination revealed a rubella specific IgM antibody. Chest X-ray suggested a chronic lung change. Rubella virus RNA was detected in the serum by RT-nPCR. This is the first case of congenital rubella, which was confirmed by the detection of rubella virus RNA, in Korea.
