Medical record of 66 eyes which had undergone pars plana vitrectomy for the treatment of proliferative diabetic retinopathy were reviewed to study their clinical features, incidences and types of complications, visual outcome, and visual prognostic factors. The final visual outcome showed the improvement in 50[76%] eyes, no change in 13[20%]eyes, and the worsening in 3[4%] eyes. Preoperative prognostic factors favoring final visual acuity included the followings:1]insulin dependent diabetes mellitus which developed before 30 years of age, 2]absence of iris neovascularization, 3]absence of tractional macular detachment. Postoperative complications included vitreous hemorrhage in 34[52%]eyes, cataract in 12[19%]eyes, increased intraocular pressure in 6[10%]eyes, rhegmatogenous retinal detachment in 4[6%]eyes, choroidal effusion in 3[5%]eyes, corneal epithelial defect in 2[3%]eyes, neovascular glaucoma in 1[2%] eye. Postoperative complications associated with poor visual outcome were rhegmatogenous retinal detachment and neovascular glaucoma.Intraoperative complication of iatrogenic retinal tear did not seem to deteriorate the final visual acuity.

The purpose of this study is to analyze ER patient's Triage and other statistical data. The subjects were 12,618 patients who visited the ER during the year 1998. The study showed the following results; 1. The male vs female ratio was 1.3 : 1.0, the male were in the majority (56.6%), and the age range of 20-29 old was the majority (15.3). The patients who visited ER at 8-10 pm were the majority (11.5%). On Sunday the number of patients who visited the ER were 2,189, and the majority were 17.4%. On Saturday the number of patients was visited the ER were 1,944 patients the second majority (15.4%). Their traffic means : the general passenger cars (75.5%), 119 or hospital ambulance (11.3%). 2.

Procalcitonin (PCT) is a useful bacterial infection biomarker with the potential for guiding antibiotic therapy. We evaluated the concordance of three automated PCT immunoassays: Kryptor (BRAHMS GmbH, Hennigsdorf, Germany), Atellica IM 1600 (Siemens Healthcare Diagnostics, Munich, Germany), and Cobas e801 (Roche Diagnostics, Mannheim, Germany). In 119 serum samples with a PCT concentration < 5.00 μg/L, Kryptor (reference assay) was compared with the other two immunoassays by Spearman’s rank correlation, regression analysis, and concordance at two antibiotic stewardship medical decision points: 0.25 and 0.50 μg/L. The Atellica IM 1600 and Cobas e801 results showed high correlations with those of Kryptor, with correlation coefficient (ρ) values of 0.97 and 0.99, respectively. However, negative biases were observed in both immunoassays (slope/y-intercept: 0.75/–0.00 for Atellica IM 1600; 0.88/–0.01 for Cobas e801). Atellica IM 1600 and Cobas e801 demonstrated excellent concordance with Kryptor at both medical decision points, with linearly weighted κ values of 0.90 and 0.92, respectively, despite discrepancies, which were more prominent at the 0.25 μg/L medical decision point. Based on these biases and discrepancies, the alternate use of different PCT immunoassays in repeat examinations is inadvisable. Standardization is required before comparing the results of different PCT immunoassays.

Heterotopic gastric mucosa in the upper esophagus is frequently found during endoscopic examination. Although most patients with heterotopic gastric mucosa of the upper esophagus, referred as inlet patch, are asymptomatic, symptomatic patients with complications resulting from this ectopic mucosa have also been reported. Acid secretion by the inlet patch has been suggested in some reports. We report a case of heterotopic gastric mucosa in the upper esophagus, with secretion of acid, demonstrated by continuous ambulatory pH monitoring, and the improvement of pharyngeal symptoms after the use of a proton pump inhibitor.

OBJECTIVES: To analyze factors associated with elderly falls in a community dwelling, a comparatively important, but somewhat neglected, health matter. METHODS: Data came from personal interview surveys using a questionnaire of 552 people aged 65 or older living in a community. Socioeconomic, and health related characteristics were investigated as independent variables and experiences of falling in the previous year as the dependent variable. RESULTS: 118(21.4%) of the elderly subjects experienced a fall in the previous year. 24 subjects experienced more than two falls, accounting for 20.3% of the elderly fall victims studied. Factors affecting the falls were families living together, level of daily activity, heart disease, and aconuresis;, therefore an elderly person who lives alone, lives independently, has heart disease, or suffers urinary incontinence had a demonstrated increased chance of falling. CONCLUSION: Groups at risk for falling included elderly persons living alone, living independently, suffering heart disease, or experiencing urinary incontinence. When an elderly fall prevention program is developed and implemented, these results should be considered.

BACKGROUND: The standard PCR with sequence-specific primers (SSP) is a widely used method of HLA-B27 typing in clinical practice. The aim of our study was to evaluate 2 Korean HLA-B27 kits with different real-time PCR chemistries. METHODS: To validate the accuracy of real-time PCR kits, we selected 28 HLA-B27-positive samples and 33 HLA-B27-negative samples with a wide range of different HLA-B specificities typed by standard PCR-SSP. The 2 real-time PCR kits used were the AccuPower(R) HLA-B27 real-time PCR kit (Bioneer, Korea) with TaqMan probes and the Real-Q(TM) HLA-B*27 detection kit (BioSewoom, Korea) with SYBR Green I dye for melting curve analysis. RESULTS: All 61 samples typed by PCR-SSP demonstrated a perfect concordance with the 2 real-time PCR assays. It was possible to clearly discriminate between HLA-B27-positive and -negative samples in both real-time assays. CONCLUSIONS: In summary, both real-time PCR assays for HLA-B27 were fast, reliable, well-adapted for routine laboratory testing, and attractive alternatives to the conventional PCR-SSP method.

PURPOSE: To determine whether an analysis of two-phase spiral CT features provides a sound basis for differential diagnosis between gallbladder carcinoma and cholecystitis. MATERIALS AND METHODS: We reviewed a total of 89 cases of gallbladder carcinoma (n=35) or cholecystitis (n=54) in patients who had undergone two-phase spiral CT. For this, a GE Highspeed Advantage scanner (GE Medical Systems, Milwaukee, U.S.A.) was used. A total of 120ml of contrast material was injected at a rate of 2 -3 ml/sec. Arterial and venous phase scans were obtained 35 and 65 seconds, respectively, after the initiation of contrast infusion. All cases of gallbladder carcinoma and 468 of cholecystitis (of a total of 482) were confirmed by histopathology. We reviewed the two phase spiral CT features, analyzing and assessing thickness of the lesion, the enhancement pattern seen during the arterial and the venous phase, invasion of the liver, pericholecystic fat infiltration, dilatation of intrahepatic ducts, and other associated findings. RESULTS: Mean wall thickness was 12.6 mm in the gallbladder carcinoma group, and 7.2 mm in the cholecystitis group. The common enhancement patterns seen in gallbladder carcinoma were a highly enhanced thick inner wall layer during the arterial phase which became iso attenuated with adjacent liver parenchyma during the venous phase (16/35; 45.7%), and 2) a highly enhanced thick inner wall layer during both the arterial and the venous phase (8/35; 22.9%). The most common enhancement pattern in cholecystitis cases was an iso attenuated thin inner wall layer during both the arterial and the venous phase (44/54; 81.5%). Findings of intrahepatic mass formation by direct invasion (9/35), lymph node enlargement (12/35), and metastasis to other organs (7/35) occurred only in cases of gallbladder carcinoma. Dilatation of intrahepatic ducts was more frequent in cases of gallbladder carcinoma (18/35, 51.4%) than of cholecystitis (10/54, 18.5%). The incidence of pericholecystic fat infiltration and fluid collection was not significantly different between the gallbladder cancer and cholecystitis groups. CONCLUSION: Gallbladder carcinoma and cholecystitis varied in terms of wall thickness, enhancement pattern, and intrahepatic ductal dilatation, as seen on two phase spiral CT. Findings of liver invasion, lymph node enlargement and distant metastasis strongly suggested gallbladder carcinoma. These results suggested that gallbladder carcinoma and cholecystitis can be distinguished by analysis of their two phase spiral CT features.
