BACKGROUND: Blood pressure (BP) control is the most-established method for the prevention of chronic kidney disease (CKD) progression. However, the ideal BP target for CKD patients is still under debate. METHODS: We performed a survey of regular registered members of the Korean Society of Nephrology to determine physician perceptions of BP control in patients with CKD. In addition, we evaluated the target BP achievement rate using data from the APrODiTe-2 study. RESULTS: Two-thirds of physicians considered the target BP for CKD to be < 130/85 mmHg. The systolic BP (SBP) thresholds for diabetic CKD, proteinuria ≥ 300 mg/day, 30 ≤ glomerular filtration rate (GFR) < 60 mL/min/1.73 m2, age < 60 years, and the presence of atherosclerotic (ASO) complications were significantly lower than the SBP thresholds of the opposite parameters. The three major hurdles to controlling BP were non-compliance with lifestyle modification and medications, and self-report of well-controlled home BP. Most physicians prescribed home and ambulatory BP monitoring to less than 50% of their patients. The target BP achievement rates using the SBP thresholds in this survey were as follows: non-diabetic (69.3%); diabetic (29.5%); proteinuria < 300 mg/day (72.3%); proteinuria > 300 mg/day (33.7%); GFR ≥ 60 (76.4%); GFR < 30 (47.8%); no evidence of ASO (67.8%); and the presence of ASO (42.9%). CONCLUSION: The target BP was lower in patients with higher cerebro-cardiovascular risks. These patient groups also showed lower target BP achievement rates. We also found a relatively lower application and clinical reflection rate of home or ambulatory BP monitoring.

PURPOSE: Laparoscopic left lateral sectionectomy (LLLS) has been widely accepted due to benefits of minimally invasive surgery. Some surgeons prefer to isolate glissonian pedicles to segments II and III and to control individual pedicles with surgical clips, whereas opt like to control glissonian pedicles simultaneously using endoscopic stapling devices. The aim of this study was to find the rationale of LLLS using endoscopic staples. METHODS: We retrospectively analyzed and compared the clinical outcomes (operation time, drainage length, transfusion, hospital stay, and complication rate) of 35 patients that underwent LLLS between April 2004 and February 2012. Patients were dichotomized by surgical technique based on whether glissonian pedicles were isolated and controlled (the individual group, n = 21) or controlled using endoscopic staples at once (the batch group, n = 14). RESULTS: Mean operation time was 265.3 +/- 21.3 minutes (mean +/- standard deviation) in the individual group and 170 +/- 22.9 minutes in the batch group. Operation time in the batch group was significantly shorter than the individual group (P = 0.007). Mean drainage length was 4.8 +/- 1.6 and 2.6 +/- 1.5 days in the individual and the batch group. There was significantly shorter in the batch group, also (P = 0.006). No transfusion was required in the batch group, but 4 patients in the individual group needed transfusion. Mean hospital stay was 10.7 +/- 1.1 and 9.4 +/- 0.8 days in the individual and the batch groups (P = 0.460). There were no significant complications or mortality in both groups. CONCLUSION: LLLS using endoscopic staples (batch group) was found to be an easier and safer technique without morbidity or mortality.

OBJECTIVES: This study aimed to evaluate the mental health status of the children of psychiatric patients in order to plan for the resources that may be necessary to help these children achieve their full potential. METHODS: Forty-eight children (age 9–18) whose parents were registered in 5 community mental health centers located in Seoul were recruited. Tests assessing 3 psychological domains were conducted: 1) cognition: Korean version of Learning Disability Evaluation Scale, Comprehensive Attention Test, 2) parent reported emotion and behavior: Korean Child Behavior Checklist, Korean attention-deficit hyperactivity disorder Rating Scale, and 3) self-reported emotion and behavior: Korean Beck's Depression Inventory-II/Children's Depression Inventory-II, Korean Youth Self Report). We defined the children as having a high risk of developing mental health problems if their test scores were over the cut-off levels in 2 or more of the 3 domains assessed. RESULTS: Twelve (25%) children were classified as having a high risk of developing mental health issues. 20 (41.6%) children scored above the cut-off in only one of the domains. CONCLUSION: Our results suggest that the children of psychiatric patients might be vulnerable to mental illness and need early prevention or interven-tions for the sake of their mental health.

BACKGROUND: Hospitals provide programs for routine screening health examination to meet the needs of people who take keen interest in the prevention of cancer and chronic diseases. But current programs do not reflect individual characteristics such as age, sex, occupation, and risk factors. Expensive diagnostic tests not based on evidence raise a continued issue of controversy. We evaluated on the scientific evidence of screening tests in these programs. METHODS: Internet home pages were searched for screening test provided by 6 major hospitals and by National Health Insurance Corporation. Screening tests were arranged by target diseases which were chosen by the authors. We reviewed the guidelines of several organizations and compared the scientific evidence of each test by the recommended guidelines. RESULTS: Excessive investigation, such as tumor markers, abdominal ultrasonography, anti-HCV Ab, and VDRL were routinely administered against recommended guidelines. Screening tests lacking sufficient evidence for recommendation were included. Furthermore, selection of the screening tests options and time interval was based on the clients' economic state and non-expert preference. CONCLUSION: Screening tests were uniformly administered in excess with insufficient evidence. Tailored screening program should be administered considering individual characteristics and risk factors.

PURPOSE: Peripheral neuropathy (PN) is known as a major contributor of the worsening of ischemic symptoms and the foot ulceration in patients with peripheral arterial occlusive disease (PAOD). However, there are few studies reporting the prevalence and risk factors for PN in PAOD. This study aimed to evaluate these issues for PN and to establish the importance of screening as additional treatment target for PN in PAOD. MATERIALS AND METHODS: A total of 52 limbs with PAOD were enrolled from January 2011 to December 2012. PN was divided into radiculopathy, ischemic PN (IPN), and diabetic PN (DPN), based on electromyographic findings. We investigated the prevalence of overall PN and subtypes of PN and then analyzed the risk factors. RESULTS: The prevalence of overall PN in PAOD was 43 of 52 limbs (82.7%). In terms of subtypes of PN, the prevalence rate of radiculopathy and IPN was 30.8% and 23.1%, respectively. DPN showed in 22 limbs (73.3%) among 30 diabetic limbs. There was no significant correlation between each type of PN and ischemic symptoms. Our analysis showed that coronary artery disease (CAD) was a significant risk factor (P=0.01) for IPN, however, did not identify any significant risk factors for DPN. CONCLUSION: This present study indicated that most patients with PAOD had PN and CAD was a risk factor for IPN. In particular, PAOD with diabetes represented a higher prevalence for DPN. Our study suggests that PN should be evaluated and considered as another treatment target in patients with PAOD.

Familial adenomatous polyposis (FAP) is a precancerous clinical entity, which is characterized by the development of numerous adenomatous polyps throughout the colon and rectum. The majority of FAP are associated with mutations of the adenomatous polyposis coli (APC) gene. Until now, more than 1,000 different APC mutations have been reported and some mutations express attenuated phenotypes which are milder forms with 10~100 colorectal polyps. We identified a novel mutation of APC gene which expressed an attenuated FAP but caused large gastroduodenal tubular adenomas requiring repeated endoscopic resections. A 16-year-old girl was referred to Incheon St. Mary's Hospital for evaluation of gastric polyposis. Initial esophagogastroduodenoscopy (EGD) showed numerous gastric polyps in the fundus and upper body and a few polyps in the duodenum. Pathologic examination confirmed gastric polyps as fundic gland polyps and duodenal polyps as tubular adenomas. Only a few colonic polyps of 2 to 5 mm in size were found on colonoscopy. Genetic analysis using polymerase chain reaction and direct sequencing revealed a novel stop codon mutation at codon 1522 in exon 16 of APC gene. At 12-month, 18-month, and 35-month follow-up EGD, large duodenal polyp and gastric polyps were removed endoscopically.

BACKGROUND: Non-small cell lung cancer is one of the most frequent cause of death due to cancer in men, and its incidence among women is rapidly increasing. Although there has been a recent surge of interest in combined modality therapy for stage III non-small cell lung cancer(NSCLC), the optimal treatment is still not well established. Thoracic irradiation has long been the gold standard for locally advanced unresectable NSCLC. However, although conventional radiotherapy(XRT) can palliate symptom and improve local control of disease, it huts at most only a modest effect on survival. Recently, cisplatin(cia-diamminedichloroplatinum ) has been reported to enhance the cell-killing effect of radiation For patients with unresectable NSCLC, cisplatin-based concurrent chemoradiotherapy(CCRT) had the advantage of therapeutic response over XRT alone and therapeutic side effect more commonly occurred in CCRT group in EORTC(European Organization for Research and Treatment of Cancer) and other trials. Objectives : We compared therapeutic response, compliance, and side effects between CCRT and XRT in patients with advanced NSCLC. Patients and METHOD: Thirty patients with biopsy-proven inoperable NSCLC were randomized to one of two treatment arms. Arm A consisted of XRT, radiotherapy for 4~6 weeks(1.8 Gy given 20~33 times, in five fractions a week), and arm B consisted of CCRT, radiotherapy for 2 weeks(3 Gy given 10 times, in five fractions a week), followed by 3 week rest period and then radiotherapy 2 more weeks(2.5 Gy given 10 timed in five fractions a week), combined with 6mg cisplatin per square meter, given daily before radiotherapy. We evaluate therapeutic response, compliance, change of performance status, side effects, and radiation pneumonitis by using the author's made scoring system. RESULTS: There was no significant difference in therapeutic response and compliance. But there was a significantly lower laboratory complication and radiation pneumonitis in CCRT group (p<0.05). There's significant negative correlation between stage and therapeutic response score in both groups(R=0.353, p<0.05). In both groups, patients with squamous cell carcinoma had a tendency to higher therapeutic response score than those with adenocarcinoma. CONCLUSION: There was. no difference between CCRT and XRT in respect to therapeutic response and compliance. But CCRT had a advantage of decreased side effects.

Purpose: To evaluate the long-term outcomes of inverted internal limiting membrane (ILM) flap and ILM insertion in idiopathic macular hole (MH) and to compare the outcomes between the two techniques. Methods: We retrospectively reviewed the medical records of 17 eyes that underwent an inverted ILM flap procedure (flap group, n = 9) or ILM insertion procedure (insertion group, n = 8) for idiopathic MH. Within each group, best-corrected visual acuity (BCVA) before surgery was compared with that at the final follow-up. The BCVA at the final follow-up was compared between the two groups. In addition, the incidence of restoration of the external limiting membrane (ELM) and ellipsoid zone was evaluated. Results: The mean follow-up period was 25.1 ± 13.7 months after surgery. All MHs were closed after the surgery. In all 17 eyes, the logarithm of minimal angle of resolution BCVA had improved significantly from a mean value of 0.88 ± 0.23 before surgery to 0.42 ± 0.23 at the final follow-up (p < 0.001). The BCVA was significantly improved in both the flap group (from 0.92 ± 0.25 to 0.37 ± 0.29, p = 0.007) and the insertion group (from 0.83 ± 0.19 to 0.48 ± 0.15, p = 0.018). There was no significant difference in BCVA at the final follow-up between the two groups (p = 0.075). The incidence of restoration of the ELM and ellipsoid zone was significantly higher in the flap group (seven eyes, 77.8%) than in the insertion group (one eye, 12.5%). Conclusions Both inverted ILM flap and ILM insertion are effective in MH treatment. The restoration of retinal outer layers was better in the flap group. Further studies with a larger study population are needed to evaluate the long-term visual outcomes of the two methods.

The purpose of this study was to evaluate the influence of fabrication methods of lithium disilicate reinforced glass-ceramic crown on marginal and internal fit. Lithium disilicate reinforced glass-ceramic crowns were fabricated using ingots for heat press forming and blocks for CAD/CAM milling manufactured by Hass and Ivoclar/Vivadent. Dentiform of maxillary central incisor was prepared with a 6°taper and 1 mm deep chamfer margin and duplicated with silicone. Then the polyurethane resin was poured at silicone mold to produce working model. Marginal and internal fit were measured by the silicone replica technique. Each silicon replica was cut into labio-lingual and mesio-distal sections and the thickness of the light body silicon was measured. Fourteen reference points were determined and measured using a microscope. As a result of calculating and comparing the average value of 14 points in all groups, the measured value was within 120 µm, the clinically acceptable range suggested by previous literatures. In all groups, the marginal fit was smaller than the internal fit. At the margin area, significant differences were identified only between the ECM group and the EPM group, and there was no statistically significant difference between the remaining groups. At the deep chamfer area, the ECM and ABM group produced by the CAD system had excellent compatibility. In the axial wall and incisal area, ECM was superior to both EPC and EPM. Also, both ABM and APC groups were statistically significantly superior than APM.
