Background: Brucellosis is one of the most common zoonotic diseases in the world. Osteoarticular complications, especially vertebral system involvement, are most commonly reported. However, reports and coreports of pulmonary complications and thoracal spondylodiscitis and epidural abscess are rare. Case presentation: Spondylodiscitis was detected at the T11–12 vertebral level, followed by epidural and paravertebral abscess, and then empyema was detected in a 17-year-old Asian female patient without any additional disease. The patient had used various antibiotics and the disease could not be proven bacteriologically. Also, the Rose Bengal test was negative. However, serologically high titer Brucella positivity was detected in the blood and pleural fluid sample. Drainage was required for bilateral empyema. Disease duration prolonged due to multiple complications. The patient was cured with combined long-term treatment for brucellosis. Conclusions: Although some are rare, brucellosis is a zoonotic disease that can cause many complications. The gold standard for diagnosis is the growth of bacteria in blood culture or tissue culture. However, isolation of the microorganism can be very difficult. Clinical suspicion and serological tests are important guides. [ABSTRACT FROM AUTHOR]

Kidney stone, also known as calcium oxalate nephrolithiasis, is one of the most common diseases worldwide. Calculi usually forms when urine becomes supersaturated with particular calcium salts such as calcium oxalate. In the present study, we investigated the ameliorative potential of the root extract of the Common golden thistle, Scolymus hispanicus L. (SH) on rats with ethylene glycol (EG) induced kidney stone disease. Sprague-Dawley rats, each weighing 250-300 g, were divided into three groups (n=6 per group): (i) Control (C); (ii) EG; and (iii) EG+SH. To induce nephrolithiasis, the rats received 1% of EG with drinking water, while the C group received normal drinking water during the study. SH extract 2 g/kg was added to the treatment from the 4th week onwards in EG+SH group. At the end of each experiment, rats were decapacitated and serum levels of calcium, magnesium, phosphorus, creatinine, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were assessed in all groups at 0, 4, and 8 weeks. Oxalic acid and creatininelevels were measured in urine samples collected at 24 h in metabolic cages. Renal tissues were evaluated histopathologically at the end of the experiment. After 8 weeks, serum creatinine levels were found decreased in the SH group while increased in the EG group. Serum magnesium and AST levels were also found decreased in the EG group, however, SH treatment reversed these values. The SH treatment also increased urinary oxalic acid levels. When the kidney tissue of EG group was examined, there was a high level of crystal/stone, especially in the renal cortex. In kidney tissues of the SH group, only small amounts of crystal/stone were observed. Our experimental findings have demonstrated the ameliorative potential of the aqueous extracts of S. hispanicus roots and shells on EG-induced in the kidney stones in rats. Isolation of active compounds of SH would be desirable to understand the biochemical mechanism behind the process better. [ABSTRACT FROM AUTHOR]

Aims: Glucose-regulated protein 78 (GRP-78) is one of the basic markers of endoplasmic reticulum (ER) stress in tissues. It is known that ER stress develops in the livers of patients infected with hepatitis C. In this study, the aim was to assess serum GRP78 levels which have not previously been investigated as a stress marker in chronic hepatitis C patients (CHC). Methods: This case control study includes patients with chronic hepatitis C (CHC) infection in our Infectious Diseases clinic (n=60) and a healthy control group without any additional chronic disease (n=60). Serum GRP78 levels were measured with enzyme-linked immunosorbent assay (ELISA), then correlation analysis was performed for serum GRP78 levels with alanine aminotransferase (ALT), aspartate aminotransferase (AST) and HCV-RNA levels. Results: A significant positive correlation was observed between HCV-RNA, ALT and AST levels in CHC patients (P<0.001 and P=0.008, respectively). Serum GRP78 was identified at similar levels in both the control and HCV subgroups. While a significant positive correlation was identified between serum GRP78 and AST levels (P=0.046), no significant correlation was detected for serum ALT levels. Conclusion: Though liver injury induced by HCV is shown to cause ER stress, our results showed there was no significant increase in serum GRP78 levels during chronic HCV infection. Amaç: Glikozla düzenlenen protein 78 (GRP-78) dokudaki endoplazmik retikulum (ER) stresinin temel göstergelerinden birisidir. Hepatit C ile enfekte hastalarda karaciğerde ER stresinin geliştiği bilinmektedir. Bu çalışmada kronik hepatit C (KHC) hastalarında bir stres belirteci olarak daha önce incelenmemiş olan serum GRP78 düzeylerinin değerlendirilmesi amaçlanmıştır. Yöntemler: Çalışmamız, Enfeksiyon Hastalıkları polikliniğimize başvuran Kronik Hepatit C (KHC) enfeksiyonu tanısı almış hasta grubu (n=60) ve ek kronik hastalığı olmayan sağlıklı kontrol (n=60) grubundan oluşan bir vaka kontrol çalışmasıdır. Serum GRP78 seviyesi Enzyme-Linked Immuno Sorbent Assay (ELISA) ile ölçülmüş, ardından GRP78 ile alanin aminotransferaz (ALT), aspartat aminotransferaz (AST), HCV-RNA düzeyleri arasında korelasyon analizi yapılmıştır. Bulgular: KHC hastalarında HCV-RNA düzeyleri ile ALT ve AST düzeyleri arasında anlamlı bir ilişki izlenmiştir (sırasıyla P<0,001 ve P=0,008). Serum GRP78 hem kontrol hem de HCV alt gruplarında benzer seviyelerde saptanmıştır. Serum GRP78 seviyesi ile AST düzeyleri arasında anlamlı bir pozitif korelasyon saptanırken (P=0,046), serum ALT düzeyleri ile anlamlı bir ilişki saptanamamıştır. Sonuç: HCV ile indüklenen karaciğer hasarında ER stresinin geliştiği gösterilmiş olmasına rağmen, sonuçlarımız kronik HCV enfeksiyonu sırasında serum GRP 78 düzeyinde anlamlı bir artış olmadığını göstermektedir.

Resistance to β-lactams in Enterobacteriaceae has been increasing worldwide. This study aimed to determine the frequency of β-lactamase genes and antibiotic resistance rates of 140 extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolates obtained from urinary tract infection in Ordu Province, Turkey. Isolates were identified by classic methods and by automated system. ESBL production was confirmed by double disk synergy test and antimicrobial susceptibility was investigated by disk diffusion method. All isolates were screened for β-lactamase coding genes from three groups (A, B, and D) by polymerase chain reaction. The highest rate of susceptible isolates was observed for imipenem (IPM, 99.3%) and ertapenem (ETP, 97.9%), and the highest rate of resistant isolates was observed for cefuroxime (97.9%), ceftriaxone (97.2%), and cefazolin (90.7%). In our study, blaCTX-M1-like group was the most prevalent β-lactamase (n = 109), followed by blaTEM (n = 68), blaCTX-M2 (n = 22), and blaSHV (n = 2). By contrast to low resistance rate to IPM and ETP, we determined blaNDM in 31 isolates (22.1%). In co-prevalence of blaNDM-1 and ESBL-coding genes, a low carbapenem resistance was determined. We can confirm that blaCTX-M1-types are still the most frequent β-lactamase coding gene in Turkey. Our study showed the highest prevalence of blaNDM-1 metallo-β-lactamase coding gene in ESBL-producing E. coli. [ABSTRACT FROM AUTHOR]

Background: Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. Aims: This study aimed to investigate the nasal colonization and treatment outcome in pediatric epistaxis patients. Study Design: Retrospective cross-sectional study. Methods: Charts of the pediatric patients referred to our university hospital otolaryngology outpatient clinics for the evaluation of epistaxis were reviewed. The patients whose nasal cultures had been taken at the first clinical visit comprised the study group. Results: Staphylococcus aureus was the most common bacteria grown. The presence of crusting and hyper-vascularity was not dependent on the type of bacterial growth and there was no relation between hypervascularity and crusting of the nasal mucosa. Thirty-six patients were evaluated for the outcome analysis. Resolution of bleeding was not dependent on nasal colonization; in patients with colonization, there was no difference between topical antibacterial and non-antibacterial treatments. Conclusion: Despite the high colonization rates, topical antibacterial treatment was not found superior to non-antibacterial treatment. Our study does not support the belief that bacterial colonization results in hypervascularity of the septal mucosa causing epistaxis since no relation was found between nasal colonization, hypervascularity and crusting. The role of bacterial colonization in pediatric epistaxis need to be further investigated and treatment protocols must be determined accordingly. [ABSTRACT FROM AUTHOR]

Adequate disinfection level of the medical equipments should be maintained to prevent cross-contamination between patients. Otoscope specula are usually cleaned and disinfected appropriately after each use by disinfectant solutions. However, since otoscope heads are electrical instruments with irregular inner surface they may still harbor pathogenic microorganisms. According to manufacturers' instructions, otoscope heads can be cleaned externally with a damp cloth and they can be disinfected with aldehydes, tensides, and alcohols. Instrument heads should not be placed in liquids. Alcohols cannot be used on glass surfaces. How often an otoscope head must be cleaned to limit contamination is not well established. This study aimed to determine whether the otoscope heads harbor pathogenic microorganisms or not. A total of 53 otoscope heads were included in the study. Swab samples were obtained from the inner parts of the otoscope heads. For bacteriological examination, cotton swabs were inoculated onto 5 % sheep blood agar, chocolate agar, and eosine methylene blue agar plates. For fungal evaluation, cotton swabs were inoculated onto Sabouraud dextrose agars. Cultured microorganisms were evaluated macroscopically and microscopically. Of the 53 otoscope heads, 22 were found to be contaminated with bacteria and/or fungi. Eleven of them were colonized by one organism, 11 were colonized by more than one organism. Only one Pseudomonas species isolated as gram-negative microorganism. Gram-positive microorganisms were isolated from the remaining 19 samples. Staphylococcus species were the most common bacteria isolated. The most common fungal isolates were Aspergillus species. Two cultures were positive with Candida albicans. The results show that decontamination of the otoscope heads is usually ignored. However, they can harbor considerable amount of pathogenic microorganisms. The probability of contamination and the risk of cross-infection is high if they are used by otolaryngologists. In order to prevent cross-contamination between patients, guidelines indicating appropriate methods and frequency of cleaning and disinfection of otoscope heads needed to be described.
