Abstract

Abstract Background and objectives: Influenza virus is the sixth cause of death in the world. We cannot differentiate it from other respiratory viruses upon clinical signs alone. This study was aimed at determining the frequency of influenza A&B antigen in pharyngeal secretion of children with upper Respiratory Infection (URI). Materials and methods: This cross sectional -descriptive study was done in pediatrics clinic of Rasoul hospital and Shahid Heidari clinic, Tehran (2006-2007). We studied the immunochromatography 149 children aged less than 14 years with URI. Rapid test was performed on pharyngeal samples of all cases. We used independent T test to compare the means of variables. (CI 95%, p<0.05). Results: The Signs of the studied children are fever (58.4%), sore throat (60.4%), coughing, runny nose and hoarseness (45%) and gastric signs (<20%) while in Influenza cases, they are 86.7%, 40% and 40% respectively. Fifteen (10.1%) of the subjects have positive rapid influenza test. The average age of the influenza case is 80 months, which is not significantly different from non-influenza cases. While no under one-year-old child has Positive influenza test, by increasing age the number of positive test is increased. As the frequency in children, aged over 10 is increased to 15.4%. There is significant difference between positive influenza test and signs such as fever, sore throat and previous antibiotic usage (p<0.5). Conclusion: Although this study was not done in epidemic period for influenza, it indicated Influenza as the etiology of 10.6% of URI. Since the cost for prevention and treatment of influenza is high and drug resistance is problematic, we can decrease the URI in non-epidemic period by mass vaccination in children, at least in high-risk cases. Key words: URI (upper respiratory infection), Influenza virus, rapid Immunochromatography Influenza test, Influenza vaccine.

Abstract

Abstract Background and objectives: Paranasal sinuses are the common place for infection in children and adults. Early and effective antibiotic treatment is necessary to reduce the infection period and mucosal injuries, and to prevent from the Involvements of orbit or CNS. This article aims to clarify the Serum immunoglobulins accompanying by Sinusitis in Children. Material and Methods: the Subjects of this Cross-Sectional study were 400 patients with paranasal sinusitis confirmed by imaging techniques. The study was conducted in infectious and ENT Clinics of Rasoul Akram hospital in 2003-2004. We measured the Levels of serum immoglobulins including IgG, IgM, IgA and IgE by standard radio-immunodiffusion test, and Compared with normal range of each age group. The data was analyzed by SPSS software (11.5) Results: The Subjects aged 4.42±2.62 are both male (70.7%) and female (29.3%). Maxilla is the most Common Sinus involved. Thirty-eight of them (95%) have increased IgG Level. Forty-four percent of children suffered from rhinosinusitis have been diagnosed with Immune-humoral disorders: the increase of IgE (N=9), Lack of IgA (N=3), decrease of Isolated IgG (N=2), decrease of both IgG and IgA (N=1) and Hyper IgM syndrome (N=3). There is Significant Correlation between different Immunoglobulins and duration of Sinusitis (P<0.05). Conclusion: The results of this study show that an increase of IgE is one of the most Common disorders in children suffering from Sinusitis and the incidence of immunity disorders is higher than the expected rate. Thus, we recommend the Immunologic assessment for Children Contracting with Sinusitis, esp. for protracted one.

Abstract

Abstract Background and objectives: The aim of this study was the detection of S.pneumoniae infection by rapid urinary test and blood culture in children with pneumonia in comparison with healthy children. Material and Methods: This case control study was carried out in pediatric ward of Rasoul Akram hospital in Tehran, Iran (2006 - 200٧).Fifty-four Community acquired pneumonia (CAP) and 50 healthy children were selected by simple sampling. The urinary antigen detection test (BINAX NOW co.) was performed on both cases and controls and blood culture was done for the cases suffered from Pneumonia. Results: Pneumococcal antigenuria is detected in 31.5 % of CAP and 6 % of controls groups. There is Significant difference between cases and controls (fisher test CI 95%, P =0.01). None of the children with nonpneumococcal Pneumonia (positive culture) has antigenuria. Conclusion: The possibility of diagnosis of pneumococcal pneumonia in children, by means of blood culture, is low. Thirty-one percent of CAP is due to S.pneumonia, by using the rapid antigenuria test. There fore, we recommend using rapid urinary antigen test, in addition to blood Culture test. Key words: CAP (community-acquired pneumonia) S pneumoniae urinary antigen test (BINAX now), Blood culture, Children

Abstract

Abstract Background and objectives: Water-born diseases are typically caused by pathogens transmitted by orofecal way. Because it is no practical and no economical and also it is time-consuming to find water-born pathogens in water reservoirs, the laboratory studies are performed on the basis of indicator microorganism. Escherichia coli is considered as the most important indicator bacterium for water monitoring. The aim of this study was to evaluate the three methods of Pour Plate (PP), Most Probable Number (MPN) and Membrane Filter (MF) in isolation of Escherichia coli in well water of Parks. Material and Methods: One hundred and sixty five samples of well water, from five geographical zones of north, south, east, west and center of Tehran, were taken in a sterile condition and sent to microbiology department of health faculty to assess with three methods of PP, MPN and MF. The results were analyzed by chi-square. Results: The results indicate that 90 water samples (54.5%) aren’t health. The samples taken from south of Tehran are most contaminant than other zones. The highest contaminated Samples (54.5%) are related to membrane filtration method in comparison with MPN (34.5%) and PP (27.3%). Conclusion: Since the MF method can recognize the contaminants quickly and effectively, we recommend it more. Based on these results, it is essential to educate children not to drink well water in parks. Keywords: well water contamination, Escherichia coli, Tehran's parks

Abstract

ABSTRACT

       Background and Objectives: Pseudomonas aeruginosa is the most frequent opportunistic pathogen isolated from the sputum of patients with cystic fibrosis (CF). Resistance to β -lactam antibiotics may arise from over expression of the naturally occurring AmpC cephalosporinases or acquired extended-spectrum β-lactamases (ESBL). The aim of this study was to determine the antibiotic resistance profiles as well as the prevalence of ESBL and AmpC production in clinical isolates of P. aeruginosa from CF patients in Tehran.

         Methods: Antibiotic resistance of 50 non-duplicate P. aeruginosa isolates was determined by the disc diffusion method. AmpC β-lactamase production was detected by the antagonism disc test and ESBL production was detected by the phenotypic confirmatory test. The presence of ESBL and AmpC genes was assessed by PCR, followed by sequencing the PCR products.

         Results: The antibiotic resistance rates were as follows: 22% to ceftriaxone, 20% to cefotaxime, 10% to imipenem, 8% to carbenicillin and 6% to ticarcillin, 4% each to cefepime, tobramycin, amikacin and aztreonam and 2% to each piperacilin, meropenem and ceftazidime. AmpC production was observed in 47 isolates (94%) and ESBL production was observed in one isolate (2%). PCR results showed that all isolates carried the blaAmpC β-lactamase gene. One multidrug-resistant isolate carried both blaTEM and blaPER-1 genes.

        Conclusion: The results showed that despite the low rate of antibiotic resistance in P. aeruginosa CF isolates,the  presence of multiple β-lactamases even in one isolate is alarming and can complicate the already difficult treatment of chronic infections in the lungs of CF patients.

Abstract

ABSTRACT
           Background and Objective: Bilophlia spp. are gram-negative, pleomorphic rod, obligate anaerobe, oxidase-negative, catalase-positive and non-motile bacteria. B. wadsworthia is type species of genus Bilophila with the additional characteristic of urea hydrolysis. B. wadsworthia can be found in a variety of anaerobe infections, particularly appendicitis and intra-abdominal infection that are considered as important opportunistic pathogens.
           Methods: This study was designed to identify Bilophila spp. in clinical specimens by culture and PCR. We examined 91 DNA samples extracted from infected appendix tissues with specific primers.
           Results: Data showed that Bilophila spp. DNA existence in 53.85% (n=49) provided appendiceal tissue.
           Conclusion: The pathological and molecular examination of infected appendiceal tissues revealed that B. wadsworthia is able to act as the primary cause of significant lesions in the appendicle tissues.
