Purpose:
To investigate whether postoperative filtering bleb size affects the surgical outcome after trabeculectomy.
Methods:
In this study, we retrospectively reviewed 145 medically uncontrolled glaucoma patients with intraocular pressure (IOP) values >21 mmHg before surgery and data from ≥2 years of follow-up. Postoperative IOP, filtering bleb size including extent and height, and other clinical factors were measured after trabeculectomy. We divided bleb extent into quadrants and bleb height by 0.5 intervals of corneal thickness. The main outcome measure was surgical success. We confirmed complete success when the IOP was ≤21 mmHg and decreased by >20% from baseline without medication or additional procedures. Qualified success used the same criteria but allowed for medication or additional procedures. Cases with reoperation or two consecutive IOP measurements <6 mmHg were considered failures.
Results:
A total of 145 eyes of 145 patients was included. The average observation period was 30.8 ± 10.9 months. During multivariate Cox regression analysis, a larger extent of filtering bleb revealed significantly low hazard ratios in both complete and surgical success (0.509 and 0.494, respectively); however, there was no significant relationship between bleb height and surgical outcome.
Conclusions
The extent of the filtering bleb was associated with surgical outcomes of trabeculectomy in glaucoma patients.

Regulation of matrix metalloproteinases (MMPs) is important for many physiological processes involving cancers, inflammation, tissue remodeling and skin aging. Here, we report the novel finding that the expression of MMP1 mRNA is downregulated by the overexpression of miR-526b which is a member of chromosome 19 microRNA cluster (C19MC). Our analysis using reporter constructs containing the 3' untranslated region (3' UTR) of MMP1 and its mutant form showed that the region from 377-383 in the 3' UTR of MMP1 is critical for targeting by miR-526b. In addition, the expression pattern of miR-526b and MMP1 mRNA showed reverse relation between adult dermal and neonatal fibroblasts. We show for the first time that miR-526b, an miRNA belonging to C19MC, can target the 377-383 region of the MMP1 3' UTR.

BACKGROUND: Group B streptococcus (GBS) infection is a leading cause of neonatal morbidity and mortality worldwide. Here, we present the analytical and diagnostic usefulness of a new real-time PCR-based assay (Xpert GBS; Cepheid, USA) for rapid and accurate prenatal GBS screening. METHODS: We enrolled 175 pregnant women who were between 35 and 39 weeks of gestation. The analytical performance of the Xpert GBS assay was first tested using a reference GBS strain. Next, to test diagnostic performance, rectovaginal swabs were obtained from pregnant women who visited the hospital for regular antenatal screening after 34 weeks of gestation. The results of the Xpert GBS assay were compared to those of standard culture for the detection of prenatal GBS colonization. RESULTS: When any positive result from Xpert GBS or culture was considered a true positive, the sensitivity of the Xpert GBS assay and culture were 91% (20/22; 95% CI [confidence interval], 72-98) and 68% (15/22; 95% CI, 47-84), respectively. The specificity of both methods was 100% (153/153; 95% CI, 97-100). The sensitivity and specificity of the Xpert GBS assay, using the culture results as a reference, were 86.7% and 95.6%, respectively. In the Xpert GBS assay, the median threshold cycle of vaginally colonized samples was significantly lower than rectally colonized samples (P<0.01). CONCLUSIONS: The Xpert GBS assay is an accurate, rapid, easy-to-use test for the detection of maternal GBS colonization in prenatal screening that might be especially useful in clinical settings where standard culture is not feasible.

BACKGROUND: Apolipoprotein E-epsilon4 (APOE-epsilon4) is a known genetic risk factor for Alzheimer's disease (AD), but its relationship with vascular risk factors is still controversial. METHODS: We retrospectively studied 56 probable AD patients diagnosed by the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorder's Association (NINCDS-ADRDA) criteria. RESULTS: The frequencies of APOE-epsilon2, 3, and 4 were 6.3%, 69.6%, and 24.1% in patients with AD. Compared to the no APOE-epsilon4 group (n=35), the APOE-epsilon4 group (n=21) revealed a higher frequency of male gender with no difference in age, educational level, dementia onset age, severity of dementia (CDR and K-MMSE), the frequencies of vascular risk factors (hypertension, diabetes, hypercholesterolemia), and total cholesterol level. High density lipoprotein (HDL)-cholesterol level was 36+/- 8 in the APOE-epsilon4 group and 43+/-11 in the no APOE-epsilon4 group with statistical significance (Student's t-test, p=0.02). In adjusting for sex, the APOE-epsilon4 group still had a significantly lower HDL-cholesterol level than the no APOE-epsilon4 group (p=0.047). CONCLUSIONS: These results suggest that there may be the genetic influence of APOE-epsilon4 on serum HDLcholesterol metabolism in AD patients.

PURPOSE: To assess the prevalence and the risk factors of dry eye disease after refractive surgery. METHODS: A retrospective study was performed on 180 eyes of 98 patients based on medical records. Those who had tear break-up time less of than 5 seconds or had an Oxford stain scale equal to or greater than 2 were defined to have dry eye disease. We analyzed the prevalence of dry eye, compared demographic and clinical features of the dry eye group and normal group, and found risk factors of dry eye after refractive surgery. RESULTS: The prevalence of postoperative dry eye was 62.2%. Compared to the normal eye group, the dry eye group had a significantly higher proportion of women (p = 0.016), older age (p = 0.001), and thin cornea (p = 0.002). The most significant risk factor of dry eye after refractive surgery was presence of dry eye before refractive surgery (odds ratio [OR] = 9.02, confidence interval [CI] = 3.8-21.4). Old age was also found to be an independent risk factor of dry eye after refractive surgery (OR = 1.06, CI = 1.01-1.11). CONCLUSIONS: The risk of dry eye after refractive surgery was increased in older age and preoperative dry eye disease. In order to prevent post-refractive surgery dry eye, caution should be exercised in middle aged patients with preoperative dry eye disease.

PURPOSE: In this study, doctors were surveyed with a questionnaire to determine whether they performed simultaneous vaccination and whether there were any concerns about safety or anxiety. The purpose of this study was to determine any problems associated with doctors readily performing simultaneous vaccination. METHODS: A trained surveyor visited 241 doctors from every institution registered with the National Immunization Program (NIP) located within six districts (gu) in the City of Busan (Dongnae-gu, Geumjeong-gu, Yeonje-gu, Suyeong-gu, Busanjin-gu, Haeundae-gu); a total of 155 (64%) valid responses were obtained. RESULTS: Of the 155 respondents, 144 (93%) were already performing simultaneous immunizations and 141 (91%) had a positive view of the practice. However, among the 144 doctors performing simultaneous immunizations, 67 (47%) were not confident about its safety; side effects were seen after simultaneous immunization by 86 doctors, 35 (41%) of whom believed that the frequency or possibility of side effects in simultaneous immunizations was higher than that in sequential immunizations. CONCLUSIONS: The use of simultaneous immunization is expanding quickly. However, among the doctors performing simultaneous immunizations, a high percentage had concerns over its unproven safety and potential side effects, indicating the need for academic societies or government institutions to present evidence to address such concerns.

BACKGROUND: The development of pedicle screw-based posterior spinal instrumentation is recognized as one of the major surgical treatment methods for thoracolumbar burst fractures. However, the appropriate level in posterior segment instrumentation is still a point of debate. To assesses the long-term results of two-level and three-level posterior fixations of thoracolumbar burst fractures that have load-sharing scores of 7 and 8 points. METHODS: From January 1998 to May 2009, we retrospectively analyzed clinical and radiologic outcomes of 45 patients with thoracolumbar burst fractures of 7 and 8 points in load-sharing classification who were operated on using two-level posterior fixation (one segment above and one segment below: 28 patients, group I) or three-level posterior fixation (two segments above and one segment below: 17 patients, group II). Clinical results included the grade of the fracture using the Frankel classification, and the visual analog score was used to evaluate pain before surgery, immediately after surgery, and during follow-up period. We also evaluated pain and work status at the final follow-up using the Denis pain scale. RESULTS: In all cases, non-union or loosening of implants was not observed. There were two screw breakages in two-level posterior fixation group, but bony union was obtained at the final follow-up. There were no significant differences in loss of anterior vertebral body height, correction loss, or change in adjacent discs. Also, in clinical evaluation, there was no significant difference in the neurological deficit of any patient during the follow-up period. CONCLUSIONS: In our study, two-level posterior fixation could be used successfully in selected cases of thoracolumbar burst fractures of 7 and 8 points in the load-sharing classification.

OBJECTIVE: To identify the etiology of hemiplegic shoulder pain by magnetic resonance (MR) arthrography. METHOD: The study included seventy-four hemiplegic patients with shoulder pain. After several physical examinations, all patients had fluoroscopically guided injection by a physiatrist with a maximum of 12~15 ml of contrast agent. Then T1-weighted, T2-weighted and fat-suppressed T1-weighted images were taken at the oblique coronal plane. In addition, fat-suppressed T1-weighted images were obtained at the oblique sagittal and oblique coronal plane. RESULTS: Except for the 9 patients who did not finish the study, the mean age of the participants was 61.5+/-8.9 years and mean duration of the cerebrovascular accident (CVA) was 15.7+/-9.7 weeks. The findings were as follows: 40% supraspinatus tendinitis, 30.8% superior labrum anterior to posterior (SLAP) lesion, 29.2% adhesive capsulitis, 24.6% supraspinatus partial tear, 23.1% biceps tendinitis, 13.8% supraspinatus full thickness tear, 7.7% infraspinatus partial tear. The SLAP lesion had significant statistic relationship with biceps tendinitis (p<0.05) but not with rotator cuff lesion. CONCLUSION: We found that causes of hemiplegic shoulder pain were various. The prevalence of the SLAP lesion was high (30.8%). We recommend the MR arthrography when the hemiplegic shoulder pain does not improve by conventional therapy or the cause of the pain is uncertain.

Pectus excavatum (PE) is known as one of the most common congenital deformities of the anterior chest wall. The Nuss procedure is an effective surgical therapy to correct PE. Here, we report a case of recurrent cardiac tamponade due to hemopericardium that occurred after 16 months following the Nuss procedure. The cause of recurrent hemopericardium was thought to be local, repetitive irritation of the pericardium by the Nuss steel bar. We should keep in mind that this serious complication can occur after the Nuss procedure, even in the late phase.
