Heterotopic pregnancy is named when an extrauterine (ectopic) pregnancy coexists with an intrauterine pregnancy simultaneously by many causes such as PID (pelvic inflammatory disease), endometriosis, IUD (intrauterine device), previous pelvic surgery and others. This is very rare in general population, with a range of occurrence estimated between 1:7963 and 1:30000. But recently the incidence has increased as the uses of ARTs (assisted reproductive technologies) including ovulation induction, IVF-ET (in-vitro fertilization and embryo transfer) and GIFT (gamete intrafallopian transfer) increase. Because this has high maternal morbidity, mortality and fetal loss, early diagnosis and proper management is very important. We report a case of heterotopic pregnancy following IVF-ET with a brief review.

Gamete intrafollopian transfer, a varient of IVF, is becoming increasingly popular as a treatment modality for infertility in women with at least one healthy follopian tube. Although GIFT has recently been poprlarized as a safe and effective treatment in selected infertile couples, little discussion of potential complications has been published. Whereas a tubal pregnancy rate of approximately 5% has been noted for IVF, early reports of GIFT have noted ectopic pregnancy to be relativiely rare. We experienced a case of combined pregnancy following GIFT with microsurgery and now present it with brief review of related literatures.

Hrr25, a casein kinase $1{\delta}/{\varepsilon}$ homolog in budding yeast, is essential to set up mono-orientation of sister kinetochores during meiosis. Hrr25 kinase activity coordinates sister chromatid cohesion via cohesin phosphorylation. Here, we investigated the prophase role of Hrr25 using the auxin-inducible degron system and by ectopic expression of Hrr25 during yeast meiosis. Hrr25 mediates nuclear division in meiosis I but does not affect DNA replication. We also found that initiation of meiotic double-strand breaks as well as joint molecule formation were normal in HRR25-deficient cells. Thus, Hrr25 is essential for termination of meiotic division but not homologous recombination.

An abnormal Korean native cow of five years old with an extra leg was observed macroscopically and radiographically. The results were summarized as follows. 1. External features included two normal forelimbs and hindlimbs, and an extra abnormal forelimb which was underdeveloped. The extra forelimb attached to the regions of back on right scapula. 2. The extra forelimb had antebrachial meromelia. It consisted of undeveloped and severely deformed scapula and humerus, fused carpal bones, imperfectly duplicated metacarpal bones, and polydactyly. The polydactyly was consisted of seven rows of digits with seven hooves, and a rudimentary hoof of dewclaw. 3. The ectopic limp was devoid of muscular tissue.

Anomalous origin of a pulmonary artery from the ascending aorta is a rare congenital cardiovascular anomaly which usually involves the right pulmonary artery. For operative reconstruction, the surgical technique of choice used to be a direct end-to-side anastomosis of the ectopic pulmonary artery to the main pulmonary artery. A case of right pulmonary artery arising from the ascending aorta associated with a contralateral patent ductus arteriosus is presented, with description of a new modified surgical technique. The operation was done on cardiopulmonary bypass with deep hypothermia. After closure of PDA, a side-to-side anastomosis between the RPA and MPA, roofed with Gore-Tex patch, was established. The postoperative course was excellent, and the postoperative angiography revealed complete anatomic correction.

Reported cases of a large dentigerous cyst involving the whole maxillary sinus are uncommon. A 22-year-old female patient suffering from swelling of the right infraorbital area and cheek with dull pain was referred to our department. Findings on computed tomography (CT) and magnetic resonance imaging (MRI) revealed a huge mass containing a displaced maxillary third molar involving the right maxillary sinus as a whole, with partial erosion of the posterior sinus cortical bone. Under general anesthesia, the mass was enucleated using the Caldwell-Luc approach, and, following histopathological analysis, was diagnosed as a dentigerous cyst. The case was followed for a period of seven years, and no evidence of sinus infection or recurring cyst formation was observed during that time.

Impacted mandibular third molars are located between the second mandibular molar and mandibular ramus. However, ectopic mandibular third molars with heterotopic positions are reported in the subcondylar or pterygomandibular space. The usual cause of malposition is a cyst or tumor, and malposition without a pathology is rare. This case report described an impacted mandibular third molar in the pterygomandibular space without any associated pathology.

The omphalomesenteric duct normally obliterates by the sixth week of intrauterine life. Incomplete obliteration results in various abnormalities which may be apparent in the newborn infant. These include fistula resembling ileum, a prolapsed loop of intestine through the umblicus and a fistula draining intestinal contents. The tract may contain ectopic tissue of stomach, colon or pancreas. Although this malformation should be recognizable at birth, 40 % of patients are not treated until after the first month of life. In the past 28 months since the Samsung Medical Center opened its doors to public, the authors have treated 4 cases of patent omphalomesenteric duct remnant including one case of T-shaped total prolapse of the duct and adjacent ileum. These cases will be discussed and the literature reviewed.

환아는 4개월부터 직장 탈출증과 심한 변비를 보였으며, 9개월에 질로부터 대변이 배출되는 증상을 나타냈으나 검사상 우측 이상 형성 콩팥 및 이소성 요관 이외 특이 소견이 없어 경과 관찰을 시행하였다. 16개월에 전신 마취하에 이학적 검사를 시행하여 누공을 확인하였고 이를 통한 대장 조영술에서 직장 중복증을 진단하여 수술을 시행하였다. 수술 시야에서 직장부터 횡행 결장에 이르는 관형의 뒤창자 중복을 확인하고, 직장-질 누공을 분리하고 결장 및 직장에는 중격절개술을 시행하였으며, 동반된 기형인 이소성 요관과 무기능 우측 신장은 절제하였다. 환아는 수술 후 3년간 잘 지내고 있다. 직장-질 누공을 동반한 관형의 뒤창자 중복은 매우 드문 선천성 기형으로 저자들의 경험을 문헌 고찰과 함께 보고하는 바이다.
