Migration of dental implants into the maxillary sinus is uncommon. However, poor bone quality and quantity in the posterior maxilla can increase the potential for this complication to arise during implant placement procedures. The aim of this report is to present a dental implant that migrated into the maxillary sinus and disappeared. A 53-year-old male patient was referred to us by his dentist after a dental implant migrated into his maxillary sinus. The displaced implant was discovered on a panoramic radiograph taken five days before his referral. Using computed tomography, we determined that the displaced dental implant was not in the antrum. There was also no sign of oroantral fistula. Because of the small size of the displaced implant, we think that the implant may have left the maxillary sinus via the ostium.

Aorto-ventricular tunnel is a rare congenital malformation, and aorto-right ventricular tunnel (ARVT) is an even less common entity. Here, we report the case of a 3-month-old female who underwent successful surgical closure of ARVT. The origin of the right coronary artery was proximal to the ostium of the tunnel.

The diffuse form of supravalvar aortic stenosis represents a surgical challenge when the ascending aorta, aortic arch, proximal descending thoracic aorta and arch arteries are involved. It can be treated by a variety of surgical approaches. We report a case of severe diffuse supravalvar aortic stenosis combined with an aortic valve anomaly and occlusion of the right coronary artery ostium in a 14-year-old boy with Williams syndrome. We enlarged the aortic root(Nick's procedure), ascending aorta, aortic arch, proximal descending thoracic aorta, and innominate artery with patches and replaced aortic valve with 19 mm St. Jude valve. Deep hypothermic circulatory arrest and retrograde cerebral perfusion were used during repair of the arch and arch artery.

Emergency operation was performed in a patient with severe aortic insufficiency caused by type A acute aortic dissection with aberrant high take-off origin of single coronary artery. The single coronary artery was found to arise from an unusual position high in the ascending aorta. Dissection was begun in the aortic root and involved the single coronary ostium. Valve competance was restored by resuspension of the commissures. the false lumen was obliterated with strips of Teflon felt and surgical glue. The aortic tissues were firmly reinforced and sutured. The proximal aortic stump was anatomically reconstructed, and fortunately the aortic valve was preserved and coronary reimplantation avoided. The patient was discharged at postoperative 13 days without specific complications. Postoperative course during the 18 months follow-up was uneventful.

A 5-year-old dog was evaluated for a lethargy and respiratory distress. Radiograph revealed cardiomegaly with pleural effusion, and the dog died during a thoracocentesis. At necropsy, the descending aorta and pulmonary trunk were dilated and in close contact, but there was no external evidence of a patent ductus arteriosus (PDA). When the descending aorta was opened however, an ostium opening into the pulmonary trunk was evident. Histopathological investigation revealed that the intramural PDA resembled vascular tissue with a structure and architecture. The diagnosis was an intramural PDA, an extremely rarely reported type of PDA in the dog.

Congenital coronary arteriovenous fistula is relatively uncommon, but with widespread use of cardiac catheterization, angiography and selective coronary arteriography are being recognized with increasing frequency. Recently we experienced one case of congenital coronary artery fistula which originated from the right coronary artery. The case was 25 year-old-male, who complained of dyspnea on exertion and continuous murmur was heard, and diagnosed as right coronary artery fistula by the cardiac catheterization and aortography. On the operation field, the right coronary artery was markedly dilated from aorta to the middle segment at acute margin of the right ventricle, which the hen-egg sized aneurysm was noticed. The dilated coronary ostium and fistular site were obliterated with several horizontal mattress sutures. And the dilated tortuous right coronary artery with aneurysm was excised. Postoperative course was uneventful and discharged without problem.

A depressariid moth, Agonopterix issikii Clarke, 1962, feeing on Orixa japonica was newly recorded from Korea. Agonopterix issikii can be characterized by the brownish forewing mottled dark brown and black scales that show a dentate line at the base and three minute blackish dots in triangular at the median, and the basally pale gray hindwing. Agonopterix issikii is similar to A. ocellana Fabricius in external appearance but can be distinguished by the presence of brownish forewing with three blackish triangular dots at the median. The male genitalia of Agonopterix issikii can be characterized by the elliptic gnathos, the triangular socius, the rectangular valva with rather straight cuiller, and the stout phallus with a short basal process and the absence of cornutus. The female genitalia can be characterized by the funnel-shaped ostium bursae, the long ducuts bursae, and the ovate corpus bursae with a rounded patch of signa. To date, 12 species of the genus Agonopterix have been recorded in Korea.

A noctuid moth, Condica dolorosa (Walker, 1865) was newly recorded from Korea. Condica dolorosa can be distinguished by the blackish forewing that shows irregular yellowish dots on the ante- and postmedian and a large pale yellowish dot at dorsum, and yellowish white discal dot with renal marking, and the basally whitish hindwing. Externally, Condica dolorosa is similar to C. cyclicoides but can be distinguished by the dark ochreous dots on dorsum of the forewing. The female genitalia of C. dolorosa are similar to those of C. cyclicoides but can be distinguished by the large bowl-shaped ostium bursae with a midventral invagination and the long ductus bursae. To date, five species of the genus Condica have been recorded in Korea.

부분 심내막상 결손증은 일차공 결손과 승모판 전엽에 열공을 동반하는 질환으로 완전형 심내막상 결손증에 비해 임상 증상이 심하지 않으나, 승모판 부전이 진행할수록 심비대, 심부전, 폐동맥 고혈압 등이 더욱 쉽게 발현되어 그 예후가 좋지 않고, 따라서 고령에서는 보기 힘든 질환이다. 본원으로 30년 전부터 증상이 있던 67세 부분 심내막상 결손증 환자가 내원하였다. 심도자 검사상 폐동맥압이 45/22 mmHg, 평균 압력은 32 mmHg로 약간의 폐동맥 고혈압이 있었고, 수술 소견상 $3.5{\times}2.5\;cm$ 크기의 일차공 결손과 심한 석회화를 동반한 승모판 전엽의 열공이 보여 일차공 결손 첨포 봉합과 승모판막 치환술을 시행하였다. 수술 후 11일째부터 심한 방설 차단이 발생하여, 영구 심박동기를 삽입하였고, 수술 27일 후 퇴원하였다. 저자들은 임상적으로 보기 드문 고령에서의 부분 심내막상 결손증을 수술적으로 교정하였기에 문헌 고찰과 함께 보고하는 바이다.

신성 고혈압은 신동맥의 협착 혹은 폐색으로 인해 유발되는 전신성 고혈압이다. 최근에는 신동맥의 재개통을 위해 PTRA가 선호되고 있지만, 복잡한 경우에 있어서는 신 자가이식이 대안적인 치료방법으로서 시행되어 왔다. 저자들은 심각한 고혈압 증상을 보인 14세 남자 환아를 PTRA 및 신 자가이식을 시행하여 성공적으로 치료하였기에 보고하는 바이다. 도플러 초음파 검사와 CT 혈관조영술상 우측 신동맥 기시부에서 약간의 좁아짐과 다발적인 측부순환을 동반한 좌측 신동맥 기시부의 완전폐색이 확인되었다. 우측 신동맥 협착의 치료를 위해 PTRA와 스텐트 삽입술을 시행하였으나 좌측 신동맥은 완전폐색으로 인해 시술이 불가능하여 좌측 신장을 절제한 후 동측 장골와에 자가이식하였다. 수술 후 시행한 도플러 초음파 검사와 MAG-3 신주사 검사상 신혈류와 신기능은 정상이었다. 혈압은 정상화되었으며 항고혈압제 투여도 점차 중단하였다. 임상적인 특성을 고려할 때 신성 고혈압의 원인은 섬유근성 형성이상으로 생각되었다. 결론적으로 신 자가이식은 혈관내 중재적 시술이 실패하였거나 불가능한 경우에 선택할 수 있는 치료방법이다.
