Rapid crestal bone resorption following maxillary tooth loss is further accentuated in the posterior regions because of pneumatization and enlargement of the maxillary sinuses. A treatment rationale that allows preservation and augmentation of vertical available bone at the time of posterior maxil-lary tooth extraction may offer numerous therapeutic benefits which are more short courses of ther-apy and no needs of additional surgical augmentation. The present study comprised 3 patients who had 4 posterior maxillary teeth with no evident bone between the tooth apex and sinus floor, as estimated through preoperative radiographic analysis. Sinus floor augmentation at the time of tooth extraction was chosen for the ltreatment of these patients. After the tooth was carefully extracted, the empty alveolus was thoroughly debrided and a trephine approach was performed. Particulated autogenous bone was gently pushed beyond the empty alveolus to elevate the sinus membrane using an osteotome. The distance between bone crest and si-nus floor was radiographically estimated 4 months after the first procedure. Another procedure was then carried out to place the implants of 11 mm length without another augmentation procedure. All implant were clinically stable, with no sign of infection. The presented surgical procedure performed at the time of extraction of posterior maxillary teeth in close proximity to the sinus floor allowed placement of implants of proper length.

The uterus with rudimentary horn occurs as a result of a lack of development during fetal life of the middle and lower parts of one of the Miillerian ducts, in which there is a failure of fusion of the two ducts, The incidence of this uterine anomaly is rare. Many cases of rudimentary uterine horn are not discovered since they do not become involved in a pregnancy, and thus remain symptomless and uncomplicated, and the diagnosis usually being made only with pregnancy with rupture. In this presentation, we describe a case of diagnosis and management of unruptured non-communicating rudimentary uterine horn pregnancy at the third trimester. The patient diagnosed by ultrasonography and MRI, was hospitalized for further evaluation and delivery under the impression of unruptured non-communicating rudimentary horn pregnancy. A living male infant weighing 1,930 gm was delivered by cesarean section at 33+l weeks due to impending preterm labor. Some articles concerned this subject were reviewed briefly to discuss relevant method of diagnosis, treatment, and clinical characteristics.

Twin pregnancy is at increased risk for congenital anomalies. Although twins were relatively infrequent, they accaunted for a disproportionately large portion of adverse pregnancy outcome, primarily as a consequence of preterm delivery, gestational diabetes, and pregnancy induced hypertension. In case of twin pregnancy with a single anomalous fetus, the clinicians are faced with difficult decision-making processes regarding the route of delivery, when to deliver, how aggressively to attempt to prevent delivery. Twin pregnancy discordant for a fetal abnormality can be managed expectantly or by selective fetocide of abnormal twin. Recently we experienced two cases of twin pregnancy with a single anornalous fetus. We reported cases with concerned literatures.

N/A Objective: The goal of this study is to determine the efficacy of rapid karyotyping from fetal ascitic fluid. Methods: In three cases of isolated fetal ascites diagnosed by prenatal ultrasonography, ultrasound guided fetal paracentesis and amniocentesis were performed and successfully obtained. Fetal karyotyping in each case at 29, 30 and 32 weeks gestation using modified lymphocyte culture method was conducted. Results: The chromosomal analysis was successful within 72 hours and abnormalities were detected in two cases and revealed trisomy 21 in each case. Our study demonstrated that the majority distribution of white blood cells was lymphocytes which ranged from 2.1 * 10(6) cells/ml to 3.7 * 10(6) cells/ml and the cell density for culture was at least than 0.35 * 10(6) cells/ml. Conclusion: The use of ascitic fluid as a cell source to achieve rapid fetal karyotyping can be valuable when cordocenteis or amniocentesis would be technically more difficult, or when rapid result is required for planning of perinatal management at late second or third trimester gestational age.

Gastric carcinoma is the most common malignancy in Korea. The peak incidence of gastric carcinoma is over 50 years of age and male predominance, about 2:1. Computed tomography scan is the one of the most useful diagnostic tool for evaluation of extension, staging and operability of gastric carcinoma. For evaluation of the utility of the preoperative computed tomography scan in gastric carcinoma, surgically proved 72 cases of gastric carcinoma were analyzed by modified Moss classification^1) based on computed tomography scan and pathological classification. The results were as follows ; 1) The accuracy of computed tomography scan in each stage of gastric carcinoma was 100% in stage Ⅰ. 67% in stage Ⅱ. 69% in stage Ⅲ. and 85% in stage Ⅳ. 2) The overall accuracy of computed tomography scan for staging of gastric carinoma was 72%. 3) The accuracy of computed tomography scan for detection of regional lymph node metastasis was 78%. and 90% for retroperitineal lymph node metastasis. 4) The accuracy of computed tomography scan for detection of distant metastasis was 90%. 5) Computed tomography scan was the most useful diagnostic method for evaluation of extension and metastasis of gastric carcinoma and it is necessary for treatment planning and prognostic evaluation before surgery
