  • Since the successful advent of IVF-ET, reproductive surgeons have been forced to compare pregnancy outcomes of surgical procedures for tubal infertility with those of IVF-ET. The current study was designed in an effort to determine the usefulness of pre-operative infertility work-up, especially diagnostic laparoscopy, in predicting the pregnancy rate and in assessing the reversal feasibility. 109 patients who underwent a microsurgical tubal reversal were reviewed. The patients were followed over one year. The total intrauterine pregnancy, spontaneous abortion, and ectopic pregnancy rates were 66.4%, 3.7%, and 7.3%, respectively. The result showed that the use of loupe might increase the chance of the ectopic pregnancy. I found that the final tubal length, especially the longest tubal length, the site of reanastomosis, and the methods of sterilization affected the pregnancy rates. A 85% intrauterine pregnancy rate was achieved in the patients with good preoperative assessments(Group II-1). There was only 10% incidence of intrauterine pregnancy in the patients with bad assessments(Group II-2). It is concluded that the pre-operative infertility work-up, especially diagnostic laparoscopy, is a good diagnostic tool in assessing the reversal feasibility.

  • Purpose : This study was carried out to identified the effects of Cultivated Wild Ginseng Pharmacopuncture(CWG Pharmacopuncture) to the rats with surgically induced endometriosis. Methods : Endometrial tissue was implanted in the serosal wall of the small intestine in rats. The rats were divided randomly into an experimental and control group. The experimental group was treated with CWG Pharmacopuncture intravenous injection to the vein of tail and the control group was given same dose of normal saline for 4 weeks. And the size of the ectopic uterine tissue was estimated, and the serum progesterone, estradiol and cytokine($TNF-{\alpha}$, IL-2, IL-4, IL-6, IL-10) concentrations were analyzed. Results : 1. The size of the ectopic uterine implants in the experimental group was much smaller than that in the control group. 2. In analysis of serum hormone, the concentration of progesterone showed higher value than that of control group and estradiol showed lower value. 3. In analysis of cytokine, $TNF-{\alpha}$, IL-2 and IL-6 concentrations showed lower value than that of control group. 4. In analysis of cytokine, IL-4 concentration showed no significant difference and IL-10 concentrations showed higher value than that of control group. Conclusion : These results indicated that CWG Pharmacopuncture is useful treatment for endometriosis.

  • Ectopic eruption is defined as abnormal eruption and results in malpositioned teeth and abnormal root resorption of adjacent teeth. Ectopic eruption, first reported by Chapman, occurs in 3% of the population and that mostly in the maxilla. Etiologic factors include narrow maxilla, large maxillary teeth, retarded calcification of the first molar, inclined eruption path of the first molar and retruded position of the maxilla. Impaction of the second molar is rare and occurs mostly in the mandible. Major causes are large teeth and insufficient arch length. Halterman has devised a method of distalizing a ectopically erupting first molar by cementing a band on the second deciduous molar with a hook soldered and a button bonded to the occlusal surface of the first permanent molar. Ectopically erupted posterior teeth should be treated early to maintain normal development of the dentition, harmony of facial growth and occlusal support, a failure to do so could result in severe malocclusion, periodontal damage and continued root resorption of the adjacent teeth. Early detection and treatment is thus vital. The author is submitting this report as he has obtained favorable results in treating a patient who came to the SNUDH Dept. of Pediatric Dentistry complaining of the first molar by using a modified Halterman appliance.

  • Meningothelial hamartoma is a benign tumor composed of ectopic meningothelial elements in the dermis and subcutaneous tissue. It mainly occurs in the scalp; however, the incidence is extremely low. The origin of meningothelial hamartoma has not been elucidated; nevertheless, it has been theorized that it derives from ectopic meningothelial rests displaced during embryologic development. It can be diagnosed histologically as proliferation of connective tissue elements and cells arranged in solid nests, resembling vascular tumors. On immunohistochemistry, it stains positively for epithelial membrane antigen and vimentin. At least 17 cases have been reported, verifying the rarity of the lesion. We present the case of a 16-year-old male patient with a soft scalp mass which was thought to be a lipoma, but turned out to be a meningothelial hamartoma on histology.

  • Objective: This study was conducted to investigate the impact of previous delivery mode on pregnancy outcomes in patients with secondary infertility after frozen-thawed embryo transfer. Methods: This prospective observational study included 140 patients experiencing secondary infertility. Of these, 70 patients had a previous cesarean delivery (CD), while the remaining 70 patients had a previous normal vaginal delivery (NVD). The primary outcome was the implantation rate. The secondary outcomes included rates of clinical pregnancy, chemical pregnancy, miscarriage, and ectopic pregnancy. Results: The comparison of all fertility outcomes between the two groups revealed no statistically significant differences. The implantation rate was 40.4% in the CD group and 41.7% in the NVD group (p=0.842). The clinical pregnancy rate was 50% in the CD group and 49.3% in the NVD group (p=0.932), while the chemical pregnancy rate was 14.6% in the CD group and 19% in the NVD group (p=0.591). The miscarriage rates in the CD and NVD groups were 20% and 17.6%, respectively (p=0.803). One case of tubal ectopic pregnancy occurred in the NVD group (1.4%). Conclusion: The mode of prior delivery did not significantly impact pregnancy outcomes following frozen-thawed embryo transfer.

  • Purpose : When the mature kidney fails to reach its norml location in the renal fossa, the condition is known as ectopic kidney. Presenting symtoms can be various and it generally depend on the associated anomaly. Beside urologic anomalies such as hydronephrosis and vesicoureteral reflux, various anomalous vascular net work, skeletal anomaly or genital anomaly can be observed in this condition. Methods : Sixteen children with ectopic kidney was studied retrospectively to analyse initial presentation, accompanied anomaly and prognosis. Results : 56% of the children were accompanied with other urologic anomalies such as true incontinence and vesicoureteral reflux that required surgical treatment. 31% of children were either diagnosed incidentally during evaluation of other non-urologic disease or during follow-up evaluation of abnormal antenatal renal sonogram. Conclusion : Ectopic kidney can be often misdiagnosed as tumorous condition or as a surgical condition depend on the abnormal location of the kidney. Careful evaluation using abdominal sonogram, DMSA, VCUG and abdominal CT scan should be performed in order to search for associated anomalous condition and for proper management.

  • Objective: To investigate the prevalence, the distribution of deciduosis, and the relationship with endometriosis in fertile women during Cesarean delivery. Methods: In this study, pelvic tissues suspicious for ectopic deciduas were taken for biopsy during Cesarean section from 154 parturients of full term pregnancy from January 1990 to December 2003. And then those patients were followed up till April 2008. Results: Tissues from 94 parturients (94/154, 61%) were evaluated histopathologically, and ectopic decidua was observed in 70.2% (66/94). Ectopic sites were ovaries only (65/94, 69.1%), ovaries and uterine serosa (12/94, 12.8%), uterine serosa only (9/94, 9.6%), and pelvic serosa. Twenty seven (27/66, 40.9%) parturients had past history of diagnosis and treatments for endometriosis. We have tried to connect 39 (39/66, 59.1%) patients who had never been diagnosed for endometriosis but pathologically confirmed for deciduosis, and 18 patients were able to contact by phone. Twelve patients (12/18, 66.6%) showed no symptoms of endometriosis and had not received any treatments for endometriosis. Conclusion: We can conclude that most of incidental cases confirmed pathologically for deciduosis during pregnancy do not symptomatically progress.

  • When many factors involved in the eruption of the teeth act as negative effects, they can cause eruption disturbance. Periodic observation, space acquirement, surgical exposure, orthodontic traction, orthodontic traction accompanied with surgical exposure, and surgical repositioning are considered as the treatment options of an impacted tooth, which is a form of eruption disturbance. In the first case, a male patient, age 9, visited Yonsei University Dental Hospital (YUDH) with a chief complaint of ectopic impaction of the upper left lateral incisor. We extracted the upper left primary lateral incisor and primary canine, and 5 months later, a window opening procedure was executed. Eight months later, the upper left lateral incisor partially erupted, and 18 months after the extraction, the axis of the tooth improved and the tooth erupted spontaneously. In the second case, a male patient, age 10, visited YUDH with a chief complaint of ectopic impaction of the upper right first premolar. We extracted the upper right first primary molar. Ten months later, the upper right first premolar erupted partially, and 19 months after the extraction, the upper right first premolar erupted spontaneously. We reported two cases in which improvement of eruption path and spontaneous eruption of an ectopic impacted tooth was achieved by extracting the deciduous tooth which interfered with the proper eruption of it.

  • In recent days, family planning is not only a problem limitted to our country but an important problem for the while world to solve. Up to present, various methods of sterilization have been developed for population control. When a patient with a previous tubal sterilization by operative method develops any symptoms and signs of pregnancy, we strongly consider it ectopic pregnancy and intrauterine pregnancy. As the cause of sterilization failure, we think that the tubal loop sloughs away and tubal ends either unite and recanalization results or heal and failure of union results in fistula. This present study considered of the 34 cases of ectopic pregnancies and 2 cases of intrauterine pregnancies after tubal sterilization by laparoscopy and Pomeroy's method, at the Dept. of Gynecol. in Kyung Hee University Hospital, during 6 years from Jan. 1977 to Dec. 1982. Authors take result in this study retrospectively. 1. Mean age was 33.7 years for the laparoscopic tubal sterilization group, 31.5 years for the Pomeroy tubal sterilization group. 2. The number of mean gravida and parity at the sterilization was 4.9, 2.8 for the laparoscopic tubal sterilization group, 4.2, 2.2 for the Pomeroy tubal sterilization group, :respectively. 3. The number of mean artificial abortion at the sterilization was all 2.2 for the laparoscopic and Pomeroy tubal sterilization groups. 4. Mean intervals from the tubal surgery to the incidental pregnancy was 3.2 years for the laparoscopic tubal sterilization group, and 3.8 years for the Pomeroy tubal sterilization group. 5. 63.3% of the laparoscopic tubal sterilization group had problem of inadequate tubal ligation, in comparison to having no inadequate problem in the Pomeroy tubal sterilization group. 6. The previous tubal sterilized scar was found to be 6 cases (17.6%) of inner portion, 15 cases (44.4%) of midportion, 13 cases (38.2%) of outer portion at the time of operation. The tubal site of ectopic pregnancy was found to be 23 cases (67.6%) of ampullary portion,S cases ( 4.7%) of isthmic and fimbrial portion, respectively. 7. The causes of table sterilization failure were, in order of frequency, technical error (19 cases), fistula formation (6 cases) and recanalization (5 cases) for the laparoscopic tubal sterilization group and fistula formation (2 cases), technical error (l case), recanalization (l case) fo the Pomeroy tubal sterilization group. 8. As the new applicated contraceptive method in incidental pregnant patient, Authors used 2 gravigard insertion for the two intrauterine pregnancy and 34 Pomeroys' tubal ligation, 2 total abdominal hysterectomy (due to associated pelvic inflammatory disease) for the 36 tubal pregnancy.

  • $\rho$-Fluorophenylalanine (FPA), a phenylalanine analog, is able to induce apoptotic cell death of human acute leukemia Jurkat T cells. To better understand the mechanism by which FPA induces apoptotic cell death, the effect of ectopic expression of antiapoptotic proteins, Bcl-2 and Bcl-xL, on FPA-induced apoptosis was investigated by employing lurkat T cells transfected with Bcl-2 gene (JT/Bcl-2) or Bcl-xL gene (1/Bcl-xL) and Jurkat T cells transfected with vector (JT/Neo or J/Neo). When Jurkat T cells, JT/Neo or J/Neo, were exposed to FPA at concentrations ranging from 0.63 to 5.0 mM, the cell viability determined by MTT assay declined in a dose-dependent manner. In addition, apoptotic DNA fragmentation along with several apoptotic events such as caspase-8 activation, Bid cleavage, mitochondrial cytochrome c release, caspase-9 activation, caspase-3 activation, and degradation of PARP was induced. However, the FPA-induced cytotoxic effect, activation of caspase-8, and cleavage of Bid were significantly abrogated by ectopic expression of Bcl-2 or Bcl-xL. At the same time, there was marked reduction in the level of cytochrome c release from mitorhondria, caspase-9 activation, caspase-3 activation, and degradation of PARP. These results indicate that caspase-8 activation, Bid cleavage, and mitochondrial cytochrome c release with subsequent activation of the caspase cascade are negatively regulated by Bcl-2 or Bcl-xL, and are thus required for FPA-induced apoptosis in Jurkat T cells
