We evaulated the effectiveness and adverse effects of deep sclerectomy with collagen implant (DSCI), which is a kind of nonpenetrating filtering surgery. In this retrospective study, DSCI was performed in 15 eyes of 11 glaucoma patients. An trabeculo-Descemet's membrane (TDM) window is created by a deep sclerokeratectomy, and the collagen implant is placed in the sclera bed under a superficial flap (deep sclerectomy with collagen implant). In 3 of 15 eyes the DSCI was intraoperatively converted to conventional filtering surgery for a large perforation of the TDM. These eyes were not included in the results of the surgical outcomes. The mean age of the patients was 50.3 +/- 14.4 years, and the mean follow-up period was 11.1 +/- 5.9 months. A diagnosis of chronic open angle glaucoma was made in 7 eyes and a diagnosis of secondary glaucoma in 5 eyes. The mean preoperative IOP was 25.8 +/- 11.9 mmHg, the immediate postoperative IOP was 6.4 +/- 2.9 mmHg, and at the final follow-up, the IOP was 11.9 +/- 2.5 mmHg. The IOP in 5 eyes was under 6 mmHg temporarily. However, there was no serious complication such as shallow anterior chamber. DSCI is considered to be a good surgical procedure that has similar surgical outcomes to a conventional trabeculectomy without serious complications.

A total of 150women with singleton pregnancies who were delivered between 37 and 42weeks gestation had ultrasound scans on elective cesarean section day. The biparietal diameter(BPD), head circumference(HC), abdominal circumference(AC) and femur length(FL) were measured in all cases. Equations of estimated fetal body weight(BWT) for Korean term fetuses using AC alone, BPD/AC, AC/FL, HC/AC/FL, BPD/AC/FL, BPD/HC/AC/FL were made by stepwise multiple regression analysis and were compared with foreign equations such as Campbell(AC), Shepard(BPD/AC), Hadlock I(AC/FL), Hadlock II(HC/AC/FL), Hadlock III(BPD/AC/FL), and Hadlock IV(BPD/HC/AC/FL). The results were as follows. 1. The equations of BWT by sonographic measurement were Equation1 (AC) logeBWT=6.105936+0.005957X(AC) (R=0.876) Equation2 (BPD,AC)logeBWT=6.53614548+0.00004963X(ACXBPD) (R=0.929) Equation3 (AC,FL) logeBWT=6.25336442+0.00751602X(FL)+0.00005155X(ACXFL) (R=0.950) Equation4(HC,AC,FL) logeBWT=6.39631346+0.00004823X(ACXFL)+0.00002023X(FLXHC) (R=0.953) Equation5(BPD,AC,FL) logeBWT=5.99934074+0.00871394X(BPD)+0.00005132X(ACXFL) (R=0.960) 2. When BPD, AC and FL were measured, the addition of HC didn,t affected to accuracy of EFW 3. The best results of all equations were obtained with our equation 5(Mean error=2.36gm, Mean absolute error=96.39gm, Mean deviation + SD(%)=0.07+0.37) and among foreign equations, the best results were with Hadlock III equation(Mean error=18.35gm, Mean absolute error=107.82gm, Mean deviation + SD(%)=-0.46+0.42) 4. The equations using AC/FL (our equation 3, Hadlock I) are more accurate than those using BPD/AC (our equatione 2, Shepard) when utilizing two parameters. Therefore, equation using AC/FL is recommended when the BPD is unobtainable at term or labor 5. The percentage of cases in which the EFW was within +5% and +200gm of the actual birth weight was highest at our equation 5 for 82% and 89%, Hadlock IV equation for 79%, 88%. 6. Our equations had relatively an equal tendency to under- and overestimate fetal weight, but foreign equations, especially Campbell and Hadlock II equations tended to underestimate. 7. Analysing according to actual birth weight, our all equations gave the most accurate estimates of fetal weigh for birth weight group between 3000-3499gm, but for birth weight group above 3500gm, that was not. At birthweight group above 3500gm, the equations depend on femur length are more accurate than the equations independ on fumr length.

Background: and Purpose: Ventricle enlargement has been implicated in the pathophysiology of Alzheimer’s disease (AD). We studied the relationship between ventricular size and cognitive function in patients with AD. We focused on the effect of the initial ventricle size on the rate of cognitive decline in patients with AD. Methods: A retrospective analysis of probable clinical AD participants with more than 2 magnetic resonance imaging images was performed. To measure ventricle size, we used visual rating scales of (1) Cardiovascular Health Study (CHS) score and (2) conventional linear measurement method. Results: Increased clinical dementia rating (CDR) was correlated with a decreased MiniMental Status Examination (MMSE) score, and increased medial temporal lobe atrophy (MTLA) and global ventricle size (p<0.001, p<0.001, p=0.021, respectively). There was a significant correlation between the change in cognitive function in the group (70%–100%ile) with a large initial ventricle size (p=0.021 for ΔCDR, p=0.01 for ΔMMSE), while the median ventricle size (30%–70%ile) showed correlation with other brain structural changes (MTLA, frontal atrophy [FA], and white matter) (p=0.036 for initial MTLA, p=0.034 for FA). Conclusions In this study, the initial ventricle size may be a potential new imaging biomarker for initial cognitive function and clinical progression in AD. We found a relationship between the initial ventricle size and initial AD-related brain structural biomarkers.

Diamond-Blackfan anemia (DBA) is a rare, inherited bone marrow failure syndrome that manifests as anemia in early infancy. Blood transfusion is a critical factor for survival. However, blood transfusions can result in iron overload. Endocrinopathies, hepatic cirrhosis, and cardiomyopathy are the most common complications of iron overload. Here, we report the case of an 18-year-old boy with DBA with hyperglycemia, short stature, and absence of puberty. The patient showed endocrine dysfunction associated with iron overload caused by repeated transfusions. He was eventually diagnosed with acquired hypopituitarism and was placed on testosterone replacement therapy. Endocrine dysfunction is common in patient with DBA, with an early manifestation of symptoms, even in teenage years. Patients receiving corticosteroid treatment or those in remission may also exhibit endocrine dysfunction, although its prevalence is the highest among chronic transfusion patients. Ongoing monitoring and evaluation of growth and pubertal development are needed for better management of these disorders.

OBJECTIVES: Clinical utility of the Short Form of the Samsung Dementia Questionnaire (S-SDQ) as a screening instrument for Mild Cognitive Impairment (MCI). METHODS: Three groups (n=27, Subjective Memory Impairment (SMI); n=41 MCI; n=79, Early Alzheimer's Disease(AD)) recruited from memory clinic were administered a battery of neuropsychological tests including S-SDQ and Korean version-Mini Mental State Examination (K-MMSE). RESULTS: S-SDQ, unlike the K-MMSE, had no association with the age and education of the subjects. Scores of S-SDQ was found to correlate (r=-.496) with scores of K-MMSE. Result of Receiver Operating Characteristic (ROC) analysis revealed that S-SDQ discriminated between the SMI and the MCI groups. CONCLUSION: S-SDQ may be a solution to the problem of contamination by education and age which affect traditional cognitive screening instruments like K-MMSE, and it may be a useful tool for screening MCI.

Background: The purpose of this study was to explore the relationship between the local extinction index and total medical service utilization. Methods: A fixed effects model in panel analysis was performed for the 228 administrative districts in Korea. The statistical yearbook on the usage of medical services by region and Korean Statistical Information Service data were used from 2010 to 2019 for analysis.Medical service utilization was represented by the number of visits day, the number of inpatient days, and medical charges. Control variables were selected by using an Anderson model. The local extinction index was calculated using resident registration population data. Results: Descriptive statistics showed that the number of areas at risk of extinction increased from 61 to 95 for the study years. In addition, the number of visits, the number of inpatient days, and medical charges all increased during the study years. After controlling for variables affecting medical service utilization and doing a panel fixed effects model, the result suggested that a one-step increase in the local extinction index was significantly associated with a 12.29% decrease in medical charges of inpatients, a 7.33% decrease in medical charge of outpatient, a 5.21% decrease in the number of inpatient day, and a 5.54% decrease in the number of visits day. Conclusion This study showed that the higher the region’s extinction risks, the higher the region’s total medical service utilization.The results of this study suggested that there was a disparity in medical service utilization between areas at risk of extinction and areas not at risk of extinction, so measures should be taken to address this disparity.

BACKGROUND: Because liver transplantation (LT) essentially accompanies the deterioration, total absence, and recovery of hepatic function, and donor hepatectomy (DH) is performed in otherwise healthy individuals, we planned to compare the postoperative pain in patients undergoing LT, DH, and a major hepatectomy (MH) for a tumor. METHODS: Postoperatively, all patients were permitted to administer patient-controlled fentanyl with a standard dosing regimen. Breakthrough pain was treated with a 25microgram fentanyl bolus. Verbal rating scale (VRS) pain scores at rest (static) and during coughing (dynamic), total fentanyl consumption, and side effects were assessed at 2, 4, 6, 12, 24, and 48 h postoperatively. RESULTS: Thirty patients (11, 10, and 9 in the MH, DH, and LT groups, respectively) were included in the study. The LT group showed a lower static pain VRS score 2, 4, 6, and 12 h postoperatively, and a lower dynamic pain VRS score 12, 24, and 48 h postoperatively than the MH group. Total fentanyl consumption was significantly less in the LT group than the other two groups throughout the study period. Postoperative nausea and vomiting were reduced significantly in the LT group than in the other two groups. No significant differences in postoperative fentanyl requirement, or static and dynamic pain, existed between the MH and DH groups. CONCLUSIONS: LT patients experienced less static pain during the early postoperative period and less dynamic pain during the late postoperative period than MH patients. DH patients had similar pain intensity and postoperative fentanyl requirements to the MH patients.

Helicobacter pylori (H. pylori) is an important risk factor for chronic gastritis, peptic ulcer, and gastric cancer. Proteinase-activated receptor 2 (PAR2), subgroup of G-protein coupled receptor family, is highly expressed in gastric cancer, and chronic expression of cyclooxygenase-2 (COX-2) plays an important role in H. pylori-associated gastric carcinogenesis and inflammation. We previously demonstrated that H. pylori induced the expression of PAR2 and COX-2 in gastric epithelial cells. Present study aims to investigate whether COX-2 expression induced by H. pylori in Korean isolates is mediated by PAR2 via activation of Gi protein and Src kinase in gastric epithelial AGS cells. Results showed that H. pylori-induced COX-2 expression was inhibited in the cells transfected with antisense oligonucleotide for PAR2 or treated with Gi protein blocker pertussis toxin, Src kinase inhibitor herbimycin A and soybean trypsin inbitor, indicating that COX-2 expression is mediated by PAR2 through activation of Gi protein and Src kinase in gastric epithelial cells infected with H. pylori in Korean isolates. Thus, targeting the activation of PAR2 may be beneficial for prevention or treatment of gastric inflammation and carcinogenesis associated with H. pylori infection.

Tailored nutritional education is generally found to be more effective in changing behaviors and to be more fully implemented than a non-tailored equivalent. This study was conducted in order to develop tailored nutritional education materials on food additives in processed foods based on need and levels of knowledge of educational targets of elementary-school students in Seoul Metropolitan City. The focus group interview was conducted with six elementary-school nutrition teachers in order to gather information and to develop a tailored quantitative questionnaire for the survey. Based on the results from 138 nutrition teachers, all answered that education on food additives in processed foods for students is necessary and both teachers and students need to receive education regarding definition, safety, and use of food additives for each processed food, in the form of video, PPT, and teaching-learning plan. Nutritional education materials for two classes were developed using video clips (grocery shopping and cooking class) about food additives in processed foods, PPTs with activity papers, two teaching-learning plans, and school newsletters to parents. In conclusion, the current study warrants conduct of further studies short-term and long-term impacts and efficacy of tailored need-based nutrition education in promotion of healthy nutrition by conveying proper scientific knowledge regarding food additives in processed foods for elementary-school students.
