OBJECT: In order to compare several Obstetric characteristics and outmmes of teenage pregnancy. METHODS: The 10 year clinical records of 11,583 women undergoing Cesarean section and delivery were reviewed in the department of Obstetrics and Gynecology, Incheon Christian Hospital from July 1, 1989 to June 30, 1999. There were seventy-eight pregnancies under age 20 and we compared them with two hundred pregnancies aged 20-29 who were randomly chosen during the same periods as the control group. RESULT: The following results were obtained. The proportion of birth by teenagers increased from 0.5% of all birth in 1989 to 2.61% in 1999. The most of cases were in high teen group, age 14- 19.The majority(50.5%) were in the age of 19. Seventy two cases(92.3%) had no previous pregnant history. Six cases had one previous pregnant history. The frequencies of prenatal care were significantly lower than that of the control group(p<0.05). The mean gestational period was 36+4weeks, and showed significant difference between the study group and the control group(39+3 weeks). The incidence of preterm labor was significantly different between the two proups(p<0.05). But the incidence of postterm delivery were not significantly different between the two groups. The mean weight gain of pregnant teenagers revealed 10.64kg, significantly less profound than the control group. The matemal weight gain of control group revealed 12.95kg, respectively. The mean birth weight(2.54kg) of infant was significantly less profound than the control group. The incidence of birth of small for gestational age(birth weight 1,500-2,499gm ; 14.5%) was significantly increased among study group than the control group(1%). The rate of abdominal delivery(21.8%) were not significantly decreased than the control group(47%). The incidence of cephalopelvic disproportion and malpresentation for cesarean section were somewhat higher than the control group, and were statistically significant(p<0.05). During the antepartun period, anemia, pyelonephritis, and preterm labor occurred more frequently in the teenage pregnancy than the control group, but not statistically significant. Among postpartum complications, incidence of anemia(51.3%) increased significantly. The perinatal mortality, intrauterine growth retardation, congenital anomaly occurred more frequently than the control group. CONCLUSION: These results show that pregnancy of teenage will be comeout high risk and complications. And then we will be more concern and study about teenage pregnancy.

OBJECT: In order to estimate the frequency and risk factors for adenomyosis. METHOD: The clinical records of 1127 women undergoing hysterectomy were retrieved in the Department of Obstetrics and Gynecology, Incheon Christian Hospital, during 7 years, from Jan. 1st 1991 to Dec. 31st 1997. RESULT: The following results were obtained. 1. Adenomyosis was found in 206 of 1127 patients(18.3%). 2. The highest incidence was 41-50 years of age group, an incidence of 55% and mean age group was 46.9 years. 3. Adenomyosis was more frequently observed in parous woman than non-parous woman, such as 8.3% and 91.7%, respectively. 4. Grossly, the size of uterus was enlarged more than 10 weeks gestational size in adenomyosis, an incidence of 62.4%. 5. Pelvic pain, dysmenorrhea and metrorrhagia were common symptom of adenomyosis, an incidence of 26.7%, 25.2% and 19.4%, respectively. 6. Myoma was the most combined disease in adenomyosis, showing the incidence of 53.4%. 7. Combined pelvic endometriosis was not observed in this study. 8. Endometrial findings of adenomyosis showed proliferative phase of normal endometrial cycle in the highest incidence, giving 72.3% of all cases. 9. Preoperative diagnostic accurracy of adenomyosis was 8.2%. CONCLUSION: This results show that deeply understanding of the common symptom and epidemiology of adenomyosis improve the preoperative diagnostic accuracy.

The aim of periodontal treatments is the complete restoration of the structure and function of damaged periodontal tissues. Although it is very difficult to attain this goal, recent advances in periodontal wound healing concepts encourage hope reaching it. Safflower seeds has been used for the treatment of blood stasis, bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine effects of the isolated extracts from Safflower seeds on mineralization of periodontal ligament cells and osteoblastic cells. Periodontal ligament cells were primarily obtained from a extracted premolars with non-periodontal diseases. Osteoblastic cells were obtained from calvariae of a fetal rat. Cells were cultured with DMEM at 37degrees C with 5% CO2 in 100% humidity incubator. Safflower seeds were isolated into the H2O layer and the butanol layer. MTT assay and alkaline phosphatase(ALP) level were examined. Also the number of bone calcification nodules were evaluated. The obtained results were as follows: 1. The cellular activity of periodontal ligament cells was significantly increased in 10(-3)g/ml, 10(-6)g/ml of both H2O layer and butanol layer of Safflower seeds. 2. The cellular activity of osteoblastic cells was significantly increased in 10(-3)g/ml, 10(-6)g/ml of H2O layer of Safflower seeds. 3. ALP level of periodontal ligament cells was significantly increased in 10-3g/ml of both H2O layer and butanol layer of Safflower seeds. 4. ALP level of osteoblastic cells was significantly increased in 10(-3)g/ml, 10(-6)g/ml of H2O layer and especilly more increaton was showed in 10(-3)g/ml of H2O layer. 5. Calcification nodules of periodontal ligament cells slightly increased in 10(-3)g/ml of both H2O layer and butanol layer of Safflower seeds. 6. Calcification nodules of osteoblastic cells slightly increased in 10(-3)g/ml, 10(-6)g/ ml of H2O layer of Safflower seeds. These results indicate that H2O layer and butanol layer of the isolated extracts from Safflower seeds has excellent effects on mineralization of periodontal cells and osteoblastic cells.

Prolonged ischemic-reperfusion induces cellular damages and apoptosis in rat skeletal muscle. Reactive oxygen species generated during reperfusion time induce expression of various genes and apoptosis. Among apoptosis-related gene products, Bcl-2 and Bax regulate the apoptotic response by inhibiting and promoting cell death, respectively. The purpose of this study was to observe the age-related alertation of expression profile of Bcl-2 and Bax in rat tibialis anterior muscle and soleus muscle following ischemia-reperfusion. 9 weeks, 30 weeks, and 65 weeks old male Sprague-Dawley rats were divided into control and ischemia groups. Ischemia group was divided into 3 subgroups based on reperfusion time. For ischemia, left commom iliac artery was occulded for 4 hours using rodent vascular clamps. The animals were sacrificed at hours 0, 3 and 24 after onset of reperfusion and tibialis anterior and soleus muscles were removed. Muscle tissues were embedded in paraffin and 6 micrometer sections were made. The expression level of Bcl-2 and Bax were examined using immunohistochemical methods. The results obtained were as follows; 1. In control group, immunoreactivities (IMRs) of Bcl-2 and Bax were weak or moderate in 30 weeks old rats and were trace in 9 and 65 weeks old rat. 2. In control group, IMRs of Bcl-2 and Bax in tibialis anterior muscle were more higher than those in soleus muscle, but not significantly. 3. In ischemia group, IMRs of Bax were increased with aging. 4. In ischemia group, IMR of Bax in tibialis anterior muscle was higher than that in soleus muscle. These results suggested that the increased IMR of Bax may be related to increasing of ischemic injury, and both old skeletal muscle and tibialis anterior muscle are susceptabile to ischemic injury of rat skeletal muscle.

Prolonged ischemic-reperfusion induces cellular damages and apoptosis in rat skeletal muscle. Such injury takes place in the phase of reperfusion following ischemia induction in part via regulating of apoptosis-related gene inductions. The present study was performed to examine the age-related alertation of expression of apoptosis in rat tibialis anterior and soleus muscles following ischemia-reperfusion. 9 weeks, 30 weeks, and 65 weeks old male Sprague-Dawley rats were divided into 2 groups such as controls and ischemia. For ischemia, left commom iliac artery was occulded for 4 hours using rodent vascular clamps. The tibialis anterior and soleus muscles were removed 0, 3, and 24 hours after onset of reperfusion. Muscle samples were embedded in paraffin and 6 micrometer sections were made. The apoptotic reactions was detected using TUNEL methods. The results obtained were as follows; 1. In control groups, the number of apoptosis was increased with aging, but not significantly. 2. In ischemia groups, the number of apoptosis was increased at 3 hours after ischemia, and decreased at 24 hours after ischemia. 3. In ischemia groups, the number of apoptosis was increased with aging. 4. In ischemia groups, the number of apoptosis in the tibialis anterior muscle was higher than that in soleus muscle. These results suggested that the ischemic injury of the rat skeletal muscle is increased with aging and that tibialis anterior muscle is more susceptabile to ischemic injury than soleus muscle.

PURPOSE: Prolonged urinary incontinence is one of the greatest concerns for patients undergoing radical prostatectomy. One of the possible causes for this urinary incontinence is a postoperative deficiency of the external striated urethral sphincter (EUS) complex and continence nerves. We evaluated the effect of posterior urethral reconstruction (PUR) in the early recovery of urinary continence after robotic-assisted radical prostatectomy. MATERIALS AND METHODS: Between January 2008 and March 2009 we performed robotic-assisted radical prostatectomy with PUR in 30 patients (PUR group) and without PUR in 30 patients (non-PUR group). We compared perioperative parameters and postoperative continence rates between the two groups. Continence was defined as no pads or one diaper per 24 hours and was assessed 1 month, 3 months, and 6 months after the procedure. RESULTS: Patients in the PUR group achieved better continence rates at 1 month (43% vs. 35%) and 3 months of follow-up (89% vs. 64%). At 6 months of follow-up, the continence rate was similar between the two groups (96% vs. 90%). No major complications were observed in the PUR group. However, 2 cases of anastomotic site leakage and 1 case of delayed bleeding were observed in the non-PUR group. CONCLUSIONS: Posterior urethral reconstruction appears to be an easy and reproducible technique in robotic-assisted radical prostatectomy. Our early experience demonstrates that PUR in robotic-assisted radical prostatectomy appears to confer early continence recovery and reduce intraoperative complications.

PURPOSE: To reassess the usefulness of criteria for lymph node size in predicting metastatic lymph node ofgastric adenocarcinoma and to determine appropriate size criteria. MATERIALS AND METHODS: We reviewed the pathology of 1669 lymph nodes from 105 gastric adenocarcinoma patients and measured their long and short axis diameters. To determine the degree of lymph node shrinkage during fixation for pathologic examination, we measured the size of 105 lymph nodes both in the fresh state and on pathology slides after fixation and obtained their correlation equation ; this was used to determine the fresh-state size of the 1669 nodes. We analysed the distribution of metastatic and nonmetastatic lymph nodes according to their long and short axis and plotted a sensitivity-specificity curve to determine the appropriate size criteria for metastatic lymph nodes. RESULTS: There were 535 metastatic lymph nodes and their mean diameter was 8.2+/-4.9mm on the long axis and 5.7+/-3.8mm on the short axis. The mean diameter of nonmetastatic lymph nodes was 4.9+/-2.8mm, 3.0+/-1.7mm on the long and short axis, respectively. There difference in size between metastatic and nonmetastatic lymph nodes was not statistically significant. The (P>0.05) distribution curve of metastatic and nonmetastatic lymph nodesoverlapped over wide range of lymph node size. We determined appropriate size criteria at the point where sensitivity and specificity curves crossed, but the form of the curves was such that this was difficult. CONCLUSION: Appropriate size criteria on lymph node metastasis were 6.2mm for #1-6 lymph node group and 8.1mm for #7-12 lymph node group on long axis diameter and 4.0mm, 5.3mm on short axis diameter. But, even with this size criteria the expected accuracy was low(67-70%). This results showed limitation of size criteria to diagnose metastatic lymph node.

A 40-year-old woman underwent surgery to remove tender bilateral vulvar masses. The masses were gray/brown, well circumscribed, non-encapsulated, and were composed of an increased number of ducts and acini with a normal lobular architecture and a duct-acinar relationship. This appearance was consistent with Bartholin's gland hyperplasia (BGH). Bilateral Bartholin's gland cysts were also associated with BGH. Benign tumors and tumor-like conditions of Bartholin's gland are uncommon, and only a few cases of BGH have been reported in the literature. Hyperplasia is a rare etiology for an enlarged Bartholin's gland, and must be distinguished histologically from adenoma.

BACKGROUND: Disseminated intravascular coagulation (DIC) is a clinicopathologic syndrome for widespread intravascular coagulation. DIC occurs when the processes that regulate coagulation break down. Staphylococcal infection is one of the causes of DIC. Staphylococcus aureus produces coagulase that can clot plasma. There are two different tests to detect the coagulase; a tube test for free coagulase and a slide test for bound coagulase or clumping factor. The goal of the present study is to evaluate the characteristics of coagulase in Staphylococcus aureus for establishment of an in-vitro model for DIC. METHODS: Coagulase tests were performed by mixing plasma with two-fold diluted culture broths, culture supernatant and culture filtrates. Coagulase activity was expressed as the reciprocal of the highest dilution titer. Cell pellets treated with normal saline, ethyl alcohol, and aceton were used for the clumping tests. Platelet aggregation tests were conducted using a culture broth and a concentrated culture supernatant. A fibrinogen binding protein was isolated from sonificated bacteria and thus, determined the molecular weight. RESULTS: Coagulase activity was higher in the broth culture than in the culture supernatant and culture filtrate. Coagulase activity decreased after incubation at 37degrees C for 24 hours but culture filtrates were clumped after boiling at 100degrees C for 10 minutes. Alcohol and aceton did not inhibit the clumping test. S. aureus induced platelet aggregation but a concentrated culture filtrate did not induce platelet aggregation. Molecular weight of fibrinogen binding protein was 57 kDa. CONCLUSIONS: It is suggested that the plasma clot was due to free coagulase or a clumping factor. Free coagulase is different from a clumping factor. We concluded that the pathogenesis of DIC in the staphylococcal infection was due to platelet aggregation triggered by a clumping factor or coagulase with other substances.

A two-year-old male Pointer had been presented with anorexia, cachexia, and weight loss of 10-day duration. Upon physical examination, fever, lethargy, superficial lymph node enlargement, and tick infestation were noted. The only abnormality in CBC and serum chemistry analyses was mild hyperglobulinemia. Spleen was enlarged by radiography, and the lymph nodes showed neutrophilic lymphadenitis by cytological examination. A polymerase chain reaction test for babesiosis and commercial ELISA tests for Ehrlichia canis, heartworm, and Lyme disease was negative except for Lyme disease, which was verified by both an IFA-IgG test and a quantitative C6 assay. Doxycycline was administered for 2 weeks and the recovery was uneventful. Post-treatment C6 titer decreased to within normal limits.
