Purpose: Procalcitonin (PCT) is a current, frequently used marker for severe bacterial infection.The aim of this study was to assess the ability PCT levels differentiate bacteremic from nonbacteremic patients with fever.We assessed whether level could be accurately rule out diagnosis bacteremia.Materials and Methods: Serum samples blood culture were obtained fever between August 2008 April 2009.PCT analyzed using VIDAS ® B.R.A.H.M.S assay.We reviewed final patient histories, including...
Objective Bkv-miR-B1-5p, one of the microRNAs encoded by BK virus, was recently reported to be elevated in blood among patients with virus nephropathy (BKVN). Urinary exosome suggested a possible source biomarker for kidney diseases, but it unknown whether could contain viral microRNA as well human microRNAs. The aim this study evaluate urinary exosomal were expressed during replication and used diagnose BKVN transplant recipients. Materials methods In cross-sectional multicenter study, we...
Mycoplasma hominis (M. hominis) and Ureaplasma urealyticum (U. urealyticum) are important opportunistic pathogens that cause urogenital infections complicate pregnancy. The aim of this study was to investigate the prevalence, effects on pregnancy outcomes, antimicrobial susceptibilities M. U. urealyticum. We tested vaginal swabs obtained from 1035 pregnant women for presence genital mycoplasmas between June 2009 May 2014. laboratory clinical aspects infection were reviewed retrospectively,...
Extended spectrum beta-lactamases (ESBLs) are cephalosporinases that confer resistance to a wide variety of oxyimino cephalosporins and create serious therapeutic problems. In addition, the quinolone qnr genes becoming increasingly prevalent in clinical isolates, some which also produce ESBL. This study was designed evaluate occurrence genotypic distribution ESBL producing Escherichia coli (E. coli) Klebsiella pneumoniae (K. pneumoniae) as well prevalence ESBL-producing isolates tertiary...
To determine whether NMLR has more statistical strength than NLR in discriminating TB from non-TB infectious lung diseases.Among patients who underwent 3 or culture tests with molecular study between January 2016 and December 2017, 110 TB, 159 diagnosed diseases were enrolled. The original complete blood count (CBC) parameters modified CBC indices, including NMLR, analyzed.The significantly lower other diseases. However, the area under curve (AUC) for (0.90; 95% confidence interval [CI],...
The aim of this study was identifying a suitable food grade enzymes to hydrolyze whey protein concentrates (WPCs), give the highest bioactivity. WPCs from ultrafiltration retentate were adjusted 35% (WPC-35) and hydrolyzed by enzymes, alcalase, α-chymotrypsin, pepsin, protease M, S, trypsin at different hydrolysis times (0, 0.5, 1, 2, 3, 4, 5 h). These 36 types hydrolysates analyzed for their prominent peptides β-lactoglobulin (β-Lg) α-lactalbumin (α-La), identify proteolytic activity each...
Purpose:The aim of this study is to investigate the molecular characteristics occult hepatitis B virus (HBV) infection in 'anti-HBc alone' subjects.Materials and Methods: Twenty-four patients with 20 control diagnosed HBV were analyzed regarding S pre-S gene mutations.All specimens for HBs Ag, anti-HBc, anti-HBs.For an anti-HBc alone, quantitative analysis DNA, as well sequencing mutation genes, performed.Results: A total 24 gene, 14 through sequencing.A simultaneously.Nineteen point...
The Abbott RealTime hepatitis C virus (HCV) Genotype II (Abbott Molecular Inc.) for HCV genotyping, which uses real-time PCR technology, has recently been developed.Accuracy and sensitivity of detection were assessed using the RNA PHW202 performance panel (SeraCare Life Sciences). Consistency with restriction fragment mass polymorphism (RFMP) data, cross-reactivity other viruses, ability to detect minor strains in mixtures genotypes 1 2 evaluated clinical samples.All viruses correctly...
A Morgagni hernia was first described in 1761 by Giovanni Morgagni. In adults, it is accompanied gastrointestinal- or respiratory-type symptoms. Herein, we report an 84-year-old woman presented to our hospital with nausea and vomiting. After hospitalization, X-ray revealed a right diaphragmatic hernia. Based on the results of abdominal computed tomography, duodenoscopy, upper gastrointestinography (gastrografin), concluded that her symptoms were caused Our patient underwent laparoscopic...
Healthcare-associated infections caused by methicillin-resistant Staphylococcus aureus (MRSA) have recently become an important issue for healthcare facilities due to high rates of infection, mortality, and treatment costs. We investigated the frequency MRSA in workers (HCWs) via nasal carriage assessed performance LightCycler® Advanced test. tested swabs from anterior nares participating HCWs at intensive care unit. Nasal were identified as S. aureus, methicillin-sensitive or...
Acinetobacter baumannii (A. baumannii) is widely known as an opportunistic bacterial pathogen that causes infection more frequently among immunocompromised individuals. Our case demonstrated the limitation of current VITEK 2 system for idendification A. baumannii. Four clinical isolates were identified Alcaligenes faecalis by system. Misidentification might lead to unnecessary tests and inappropriate treatments. Additional methods appear be helpful accurate identification microbiology laboratories.
Hepatitis B surface antigen (HBsAg) is known as the hallmark of hepatitis virus (HBV) infection. This study aimed to determine whether an HBsAg neutralization test necessary accurately interpret results.Initially reactive specimens from a 5-year period, with cutoff index values between 1.0 and 2.0, were subjected confirmatory testing using Elecsys Confirmatory kit (Roche Diagnostics GmbH. Mannheim, Germany).The showed 46.1% positive (confirmed group) 53.9% negative results total specimens....
Crystalloid podocytopathy with focal segmental glomerulosclerosis in plasma cell myeloma (PCM) is rare. We present a case of crystalline deposition the bone marrow (BM) and various renal cells only proteinuria as symptom. As workup for proteinuria, biopsy sample was obtained. EM showed multiple depositions tubular podocytes. Focal crystalloid diagnosed. Because monoclonal gammopathy detected serum urine, BM study also performed. Plasma needle-shaped inclusion bodies were observed. The...
The nucleotide sequence of 1731, a retrotransposon cloned from the genome Drosophila melanogaster , reveals structural similarity with proviral form retroviruses including pol ‐like gene containing putative reverse‐transcriptase(RT)‐coding sequence. Diverse parts that were subcloned and expressed in Escherichia coli . It has been demonstrated expression RT‐like sequence, when translated, gives rise to peptides displaying enzyme activity characteristic true RT enzyme. In addition, rabbit...
Chromobacterium violaceum is a gram negative straight rod, 0.8-1.2 by 2.5 to 6.0 m, which motile one polar flagella μ and four lateral flagella.The organism inhabits soil water often found in semitropical tropical climates.Infections humans are rare.We report case of infection caused strains C. violaceum.A 38-year-old male patient was admitted KyungHee University Hospital, Seoul, Korea on July 28 th , 2003, after car accident.The had multiple trauma lacerations.He an open wound the left...
A saccular cyst is defined as a dilated saccule of the larynx, filled with mucus, and located between false vocal cords thyroid cartilage. Although this uncommon laryngeal condition benign in nature, it could lead to dyspnea, stridor, airway obstruction, depending on its size location. Furthermore, some cysts have been associated carcinoma. This study aimed characterize rather aid determining proper management pathology.Medical records were retrospectively reviewed all patients diagnosed...
