Page 2Context: Staphylococcus aureus and coagulase-negative staphylococci (CoNS) are the most frequently isolated pathogens and are responsible for approximately two-thirds of joint replacement infections..
Evidence Acquisition: Although both belong to the staphylococci genus, there are several epidemiological and therapeutic differences between S. aureus and the heterogenous group of CoNS. In general, however, preventive and therapeutic recommendations for Prosthetic Joint Infection PJI due to CoNS do not differ from PJI caused by other pathogens..ResultsThe main differences between the pathogens lie in the clinical presentation of PJI, the presumed origin of infection, and the presence of a higher proportion of methicillin-resistant strains leading to a limited choice of antibiotic agents..ConclusionsFortunately, due to its lower virulence as compared to its cousin S. aureus, PJI due to CoNS may display higher remission rates than S. aureus-caused PJI after combined surgical and medical management.Keywords: Orthopedic Infections, Epidemiology, Coagulase, Negative Staphylococci, Treatment, Perioperative Antibiotic Prophylaxis, Prosthetic Joint -
Page 10BackgroundInvasive fungal infections (IFI) represent a serious threat for severely immunocompromised patients. Infection control interventions, including protective environment (PE) implementation, are essential to reduce IFI incidence, mortality and burden of hospitalization, among high-risk patients. Information about the impact of these strategies in cancer patients with chemotherapy-induced neutropenia (CIN), in developing countries, is insufficient..ObjectivesTo assess the impact of PE implementation on IFI incidence, consumption and cost of antifungal treatment, in a general, tertiary teaching hospital, in Southern Brazil..
Patients andMethodsWe conducted a quasi-experimental study to evaluate an institutional intervention, in a hospital ward, for patients with CIN, which consisted in renovation of the ward and measures involving air-quality technologies installation, the main one being high efficiency particulate air (HEPA) filters. Simultaneously, infection control routines were implemented. Neutropenic patients, admitted to any other hospital ward, prior to the renovation, were included in the historical control group. The IFI incidence was defined, according to the criteria proposed by the European Organization for Research and Treatment of Cancer. Direct costs of antifungal drugs were recorded, for all neutropenic patients..ResultsA total of 190 and 181 hospital admissions were included in the intervention and control groups, respectively. Total IFI incidence was reduced in the PE group (7.4% vs. 18.2%; P = 0.002) and the same was observed when considering only proven and probable IFI (1.6% vs. 8.3%; P = 0.003). This benefit persisted even after adjusting for antifungal prophylaxis (OR = 0.17; 95% CI = 0.05 ‒ 0.60). We observed a decreasing trend in molds and yeasts IFI incidence, in the intervention group. Although the final cost of antifungal agents was lower, after intervention (78347.37 USD vs. 154176.60 USD), the median cost per admission did not differ between groups (1.00 USD = 1.9 Brazilian Real, in May 2007). Considering all admissions with IFI, the median cost was significantly higher than recorded in admissions without IFI..ConclusionsThis study showed that preventive measures, including PE implementation, reduce IFI incidence in patients with CIN, admitted in a hospital in a developing country. This suggests that those strategies may overcome their costs on the long-term, by saving costs associated with fungal infections..Keywords: Neutropenia, Mycoses, Aspergillosis, Infection Control, Ventilation, Cost Savings -
Page 19BackgroundThe extracts of many plants have been used for their applications in the prevention of bacterial growth; however, these applications need more investigations..ObjectivesThe major aim of the current study was to investigate the antimicrobial activity of an extract of the Peganum harmala flower and Heracleum persicum against Acinetobacter baumannii..Materials And MethodsThe minimum inhibitory (MIC) concentrations Minimum Bactericidal Concentration of extract and essential oil were investigated by microdilution method and antibiotic resistance was evaluated using the disk diffusion test..ResultsIn this study, the levels of MIC extract and essential oil of Peganum harmala were observed in ranges from 6.25 ppm to 12.5 ppm and 3.1 ppm to 25 ppm, respectively. The highest MIC value was observed as 12.5 ppm in A. baumannii. The levels of MIC extract and essential oil of Heracleum persicum were observed in ranges from 5 ppm to 20 ppm and 12.5 ppm to 10 ppm, respectively. The highest level of MIC extract and the highest essential oil value of Heracleum persicum were observed as 20 ppm and 10 ppm, respectively, in A. baumannii..ConclusionsResults of this study suggest that the extract alone of Peganum harmala and Heracleum persicum may be useful to treat bacterial infections..Keywords: Minimum Bactericidal Concentration, Peganum harmala, Heracleum persicum, Acinetobacter baumanni

Page 23BackgroundHepatitis C virus (HCV) infection is an important global concern, with a frequency of 3% (i.e., 170 million of the population has HCV-Ab). Additionally, 50% of HCV and 80% of transfusion transmitted infections (TTI) are chronic. In 20% of cases, HCV occurs as an acute infection, and in the remaining 80% of cases, it becomes chronic. In chronic patients, risk of cirrhosis is up to 44%, risk of hepatocellular carcinoma (HCC) is 13%, and risk of mortality is 14%. As there is no vaccine available for the virus yet, and since most of the cases are asymptomatic, attention to the epidemiology of the disease among the population is a pressing concern..ObjectivesThe aim of this study is to determine the prevalence and risk factors of HCV in Birjand city..
Patients andMethodsIn this descriptive-analytical study, 5,235 people who live in Birjand city were selected; after gaining permission for the study, a signed consent form was obtained from each patient. Prevalence of HCV was determined by ELISA test, and positive cases underwent Polymerase chain reaction (PCR) and genotyping for confirmation..ResultsThe mean age of the participants was 39.7 ± 14.4. Among them, 52.2% were female and 29.9% had university degrees. Prevalence of HCV-Ab was about 0.2% with ELISA, and 0.14% of entire group were confirmed by PCR. No significant relationship was found for age, sex, and education (P > 0.05). Also, there was no significant relationship found with risk factors such as endoscopy, blood transfusion, surgery, hospitalization, phlebotomy, and alcohol drinking (P > 0.05). HCV-Ab was 200 times more prevalent in IV-drug abusers compared to non-addicted people. Also, the prevalence of HCV-Ab in non-IV-drug abuser addicts was 9.3 times higher than in non-addict patients. Prevalence of HCV-Ab in patients who reported illicit sexual activities was 13.3 times higher. In patients with a familial history of HCV, infection was 26.3 times more prevalent than in patients with no familial history (PConclusionsIn this study, the prevalence of HCV was 0.2%, which is lower than the mean prevalence in Iran (1%). Prevalence of HCV had a significant relationship with IV-drug abuse..Keywords: Prevalence_Hepatitis C (HCV)_Risk Factors -
Page 28BackgroundA growing number of elderly patients are hospitalized for various causes and age has been described inconsistently as a risk factor for acquiring nosocomial infections with a subsequent higher mortality rate compared to younger patients..ObjectivesTo describe the incidence, type, and microbiological characteristics of nosocomial infections in elderly and non-elderly patients..
Patients andMethodsRetrospective analysis of all hospital-acquired infections (HAIs) in an academic community hospital. Patients were stratified into two groups: non-elderly (18 - 64 years) and elderly (> 65 years)..ResultsA total of 18469 patients were included (108555 hospital days) in this study. About 79.6% of HAI were infected non-elderly and 20.3% elderly (P 0.05). Hospital mortality increased with every HAI diagnosed per patient..ConclusionsThe study showed that HAIs were more frequent in elderly population predominately with respect to VAP and infections by Gram-negative pathogens. Overall mortally was greater in the elderly group although the odds ratio for death was higher in younger patients and increased with every HAI diagnosed..Keywords: Elderly, Gram, Negative Bacteria, Cross Infection, Mortality, Ventilator, Associated, Pneumonia -
Page 33BackgroundFebrile convulsions are seizures associated with fever during childhood. They generally have excellent prognosis. However, as they may signify a serious underlying acute infectious disease, each case must be carefully examined and appropriately investigated..ObjectivesThe aim of this study was to investigate the causes of infectious diseases, which tend to get into febrile convulsion in patients hospitalized in 17th Shahrivar Hospital in Rasht city, Iran..
Patients andMethodsThis descriptive cross-sectional study was conducted on all children hospitalized with infectious diseases in 17th Shahrivar Childrens Hospital in Rasht city, Iran, between August 2008 and August 2009. They were recruited using the convenient method. Data were collected using a form including age, sex, season of admission and possible diagnosis and analyzed by descriptive statistics (mean, standard deviation and frequency) using SPSS software version 16..ResultsIn this study, 191 patients (14%) had febrile convulsion. According to the results, respiratory tract infection was mentioned in 97 cases (47.3%) and considered as the leading cause of fever..ConclusionsAccording to results, it seems that clinicians should assess patients with infectious disease thoroughly to prevent further health problems..Keywords: Seizures, Febrile, Infection, Children -
Page 36IntroductionVaricella gangrenosa is an uncommon but serious complication of chicken pox in young children. It should be suspected in any child with a history of varicella infection and increasing complaints of pain and swelling in an extremity or other body area, along with increasing fever, erythema, lethargy, and irritability. Early surgical intervention with intensive antibiotic therapy is essential to prevent fatal consequences..Case PresentationWe describe a case of a previously healthy child who presented with sepsis due to varicella gangrenosa. While she initially responded well to a conservative antibiotic and acyclovir treatment, her subsequent rapid deterioration required urgent and repeated debridement..ConclusionsThis report highlights the significance of prompt diagnosis and early surgical intervention for management of varicella gangrenosa..Keywords: Debridement, Fasciitis, Sepsis
