Odontogenic keratocysts (OKCs) are one of the most aggressive cysts in the oral and maxillofacial area because of their high recurrence rate and infiltrative behavior. In growing patients with OKCs, a radical treatment approach might cause numerous complications, including the disturbance of jaw growth and loss of the involved tooth. This case report describes successful comprehensive orthodontic treatment combined with marsupialization of the cyst in a young girl who exhibited an OKC with impacted teeth. The 10-year-old girl presented with an OKC extending from the mandibular symphysis through the left mandibular body, with ectopic impaction of the mandibular left canine and first premolar, as well as congenitally missing bilateral mandibular second premolars. Interestingly, spontaneous improvement of the positions of the ectopic impacted teeth, along with a reduction in the size of the cyst, occurred during marsupialization. The sequential use of removable and fixed appliances enabled orthodontic traction of the impacted teeth. The treatment outcome was stable at 2.5 years after the end of the treatment. We speculate that comprehensive orthodontic treatment combined with marsupialization can be an effective treatment strategy for patients with OKCs, especially when they are encountered in young, growing patients with impacted teeth.

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.

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.
