3.Additional Subconjunctival Low Dose 5-fluoro u racil Injection after Mitomycin C Applied Filtering Surgery in Glaucoma Patients.
Journal of the Korean Ophthalmological Society 2000;41(1):197-204
To evaluate the additive efficacy of postoperative low dose 5-FU subconjunctival injection, we analyzed 43 patients[43 eyes]who had undergone trabeculectomy or triple surgery with intraoperative MMC for 2.5~3min.18eyes[case group =MMC 5-FU group]of 43 eyes had postoperative low dose 5-FU injection additionally and 25 eyes[control group =MMC group]of which had only undergone intraoperative MMC. The mean[+/-SD]follow-up periods were 13.6 +/-5.3 months in MMC 5-FU group and 12.1 +/-3.6 months in MMC group.There was no statistically significant difference in preoperative IOP between the two groups[p>0.05].Mean postoperative intraocular pressures were 12.9 +/-4.2 mms of mercury in MMC 5-FU group and 13.3 +/-4.4 mms of mercury in MMC group at 12 months postoperatively[p>0.05]. Kaplan-Meier survival analysis showed that the cumulative success rates at 1.5 year were 82.6%and 87.2%in the case and control groups, respectively[p>0.05].Of the postoperative complications, corneal epithelial defect was more frequent in MMC 5-FU group[p<0.05]. In conclusion, postoperative injection of low dose 5-FU additionally did not have an additive effect on the IOP control in patients undergone MMC applied filtering surgery. We may need additional postoperative injection of higher dose of 5-FU.Or, we may need to individualize the duration of application or the concentration of intraoperative MMC to begin with.

4.RADIOGRAGHIC STUDY OF MARGINAL BONE LOSS AROUND OSSEOINTEGRATED IMPLANTS AFTER FUNCTIONAL LOADING.
The Journal of Korean Academy of Prosthodontics 1998;36(6):806-815
Regular radiographic examination has been considered as an essential diagnostic method for the osseointegrated dental implantation. This study investigated the marginal bone loss through the measurement on the periapical radiograph around 46 endosseous dental implants. Marginal bone loss have been observed for 5 years after delivery of prostheses. The results were as follows : 1. According to the experimental periods, average marginal bone loss in total implant was 1.821mm in the first year, 1.833mm in the second, 1.892mm at third, 1.910mm at forth and 1.957mm at fifth after delivery of prostheses(P<0.05). 2. The average bone loss was 1.832mm in the maxillae and 1.819mm in the mandible in three years but there was no significant difference between the upper and lower jaw(P>0.05). 3. The average bone loss was 1.824mm in males and 1.818mm in females in five years but there was no significant difference according to the sex(P>0.05). These results indicate that the most of the alveolar bone loss occur within the first year after delivery of dental prostheses resulting in the exposure of polished neck positions, and the bone level stabilizes at first thread portion of the implant fixtures

Angiomyolipoma is considered by many authors to be a hamartoma, occurring in a sporadic form or in association with tuberous sclerosis. This lesion consists of thick walled blood vessels, smooth muscle, and mature adipose tissue in varying amounts. We have experienced a case of the angiomyolipoma composed of monotypic epithelioid cells. The patient was a 69-year-old female. Clinically, there was no evidence of tuberous sclerosis. Microscopically, the tumor was composed of polygonal cells with abundant eosinophilic granular or clear cytoplasm, pleomorphic nuclei, prominent nucleoli, and multinucleated giant cells. The tumor cells showed positive reaction for HMB45, CD68, smooth muscle actin, and S-100, and negative reaction for epithelial membrane antigen, cytokeratin, vimentin, desmin, CD34, estrogen receptor, and progesterone receptor. Ultrastructual analysis showed the presence of glycogen, mitochondria, and other microorganelles in neoplastic cells. Melanosome or premelanosome was not identified.

OBJECTIVES: The purpose of this research is to help solve adolescent issues involving substance uses, which may become begin to undergo many changes(i. e. practising various roles, thereby leading to independent life styles). More often than not, adolescent drug problems develop into social problems, chiefly behavioral imitations and heavy dependence on medicine. The authors conducted a survey of adolescent substance uses to develop preventive measures against the drug habit prevalent among young people, thereby formulating a policy to deal with problematic community. Funded by a Youth Counselling Center in the city of H. the research was conducted on the following assumptions that there will be:Firstly, a comparison of drug uses by sex and age:Secondly, variance of substance users by family background and peer group:Thirdly, a combination of heavy drinking, smoking and delinquency resulting in the drug habit. METHODS: The survey included a total of 1613 students during 3 days, 12 through 14, July, 1999. The subjects were 833 pupils(51.6%) from 4 middle schools and 780 students(48.4%) from 3 high schools in the city of H with a ratio of 49.5 %(males) and 50.5%(females). RESULTS: 1) Experience of substance use is most referable to drinking(59.4%) and smoking(34.4%) while given to analgesics(33.1%) among medicines, glue(0.7%) among inhalants and philophone(0.4%) among narcotics. 2) High school students found more than double the amount of smoking and drinking as well as uses of hypnotics, stimulants and sedatives by junior high school students. 3) Our resalt showed was significantly noted that non-users had a better relationship with their parents than most users. 4) Smoking and drinking problean could be more easily developing into adolescent substance uses. 5) Alcohol, cigarette, and drug users showed more misconducts than other adolescents. 6) Most adolescents believe that drinking is necessary for making friends(55.0%), while smoking is just for killing time(50.9%). 7) Drinking, smoking, and other substance users were found to develop into more problematic habits. CONCLUSION: The present survey and several others show that adolescent substance uses in Korea are on the rise. Therefore, extensive counter-measures will be necessary followed by nationwide epidemiological survey of the pending issue, with the psychiatrists participating in the campaign.

OBJECTIVE: To evaluate whether co-culture of oocytes on vero cell monolayers from Day 0 (Day 0 group) after egg retrieval results in an increase in developmental capacity such as fertilization rate, embryo quality, blastulation and clinical pregnancy rate compared with co-culture of oocytes from Day 1 (Day 1 group). METHODS: Sperms were treated with Hams F-10 supplemented with 10% human follicular fluid (hFF). Vero cells for co-culture were prepared in TCM-199 with 10% FBS. Oocytes were co-cultured from Day 0 and fertilized oocytes were co-cultured from Day 1 on vero cell monolayers in DMEM with 10% and 20% hFF, respectively after egg retrieval. On day 1, 2 and 5, fertilization rate and grade of embryos and blastocysts were evaluated. Results (fertilization rate, cleavage rate, grade of embryos and blastocysts and pregnancy rate) were considered statistically significant when p value was less than 0.05 using t-test and ci2. RESULTS: In sibling oocytes of same cycles, no differences were found in fertilization rate (94.6 vs. 91.4%), cleavage rates (94.6 vs. 91.4%), embryo grade (on day 2 and 3) and blastulation (65.6 vs. 57.0%) and their grade. In different oocytes of different cycles (patients), no differences were found in fertilization (79.8 vs. 78.3%), cleavage rates (77.7 vs. 76.4%) and blastulation (56.0 vs. 45.3%), but pregnancy rate was higher in the Day 0 group than in the Day 1 group (60.0 vs. 42.9%). CONCLUSIONS: This study revealed that the embryonic development capacities were not affected by the different co-culture time in the sibling oocytes of same cycles. Although no statistical significance, because of small size of study, there was a trend for higher pregnancy rates in Day 0 group compared to Day 1 group in different oocytes of different cycles.

OBJECTIVE: The purpose of this study was to evaluate the outcome and safety of vaginal delivery after previous cesarean birth. METHODS: This study was based on 303 cases of delivery with previous cesarean birth at Masan, Fatima Hospital from May, 1997 to April, 1998. Among them, 62 cases had performed trial of labor. We had made a comparison between elective repeat section group and trial of labor group by analizing the frequency, successful rate, maternal morbidity, perinatal morbidity and mortality. RESULTS: Among 303 cases with previous cesarean birth, trial of labor was done in 62 cases(20.5%). Among trial of labor group, vaginal delivery was done in 54 cases (87.1%) and repeat section was done in 8 cases(12.9%). Indications for elective repea section before the onset of labor were refuse trial of labor(51.9%), request for tubal ligation(17.4%), and previous section > or =2(7.5%), etc. The successful rate of vaginal delivery according to indication for previous cesarean birth was 85.0%(17/20) in the cases of dystocia and 88.1%(37/42) in the cases except dystocia. The successful rate was not influenced by the indication for previous cesarean birth(P>0.05). There were no maternal death or uterine rupture in the cases of trial of labor. There were no significant difference between elective repeat section group and trial of labor group in maternal morbidity, perinatal morbidity and mortality(P>0.05). CONCLUSION: Under strict indications, vaginal delivery subsequent to cesarean birth may be safe, and can reduce the rate of cesarean section that was increased constantly.

PURPOSE: This study was aimed at assessing the difference of the prevalence of iron deficiency and iron deficiency anemia among rural and urban middle school students in relation to dietary habit. METHODS: With a questionnaire, blood samples were obtained from 439 apparently healthy rural and urban middle school students residing in Ulsan. Anemia was defined as hemoglobin level of 12.6 g/dL or less for boys and 11.9 g/dL or less for girls. Iron deficiency was defined as serun ferritin level less than 12 micrograms/L or/and transferrin saturation less than 14%. Iron deficiency anemia was defined as iron deficiency plus low hemoglobin. RESULTS: 1) In boys, the prevalence rate of anemia was 17.2%. Among these anemias, 5.4% were found to be iron deficiency anemia. In girls, the prevalence of anemia increased with age. The prevalence of iron deficiency anemia was 6.9%. 2) In girls, the prevalence rate of anemia in rural area was higher than that of anemia in urban area (12.6% in rural, 6.1% in urban, P<0.01). 3) The prevalence of anemia and iron deficiency in the students with menstruation was 10.6% and 33.1%, which was higher than the prevalence of 2.5% and 7.5% in those who did not have the menarche (P<0.001 and P<0.001, respectively). 4) Dietary intake of rural and urban middle school students was estimated lower in energy, iron than the recommeded dietary allowance (RDA). In girls, dietary intake of rural middle school students was estimated lower in iron, niacin, and vitamin C than that of urban middle school students. 5) Nutritional factors such as energy, carbohydrate, protein, and phosphorus showed positive correlation with RBC, hemoglobin (P<0.05). CONCLUSION: It is recommended to enforce the nutritional education to take enough iron in middle school students to reduce the high prevalence rate of anemia among pubertal students.

BACKGROUND: To determine whether olecranon fractures have osteoporotic features such as age-dependent, low bone attenuation and low-energy trauma as a cause of injury. METHODS: Elbow computed tomography (CT) and medical record review were performed in 114 patients (53 males and 61 females) with acute olecranon fractures. The mean age was 57 years. Bone attenuation was measured on the central part of the olecranon on sagittal CT images avoiding the fracture, and on the distal humerus (distal metaphysis and medial and lateral condyles) on coronal CT images. We compared bone attenuation and causes of injury (high or low energy trauma) between younger (<50 years) and older (≥50 years) patients in each gender. Multiple regression analysis was performed to determine the effect of age and gender on bone attenuation. RESULTS: Mean bone attenuation in older male and female patients was significantly lower than in younger patients, except at the medial condyle in men. The proportion of low-energy trauma in older male patients was significantly higher than in younger male patients. In female patients, low-energy trauma was predominant in both younger and older patients. Age and female gender had significantly negative effects on bone attenuation. CONCLUSIONS: This study demonstrated that olecranon fractures have osteoporotic features, including age-dependent low bone attenuation and low-energy trauma as the predominant cause of injury. Our results suggest that osteoporosis evaluation should be considered for patients aged 50 years or more with olecranon fractures.
