Survey of cases with sepsis & septic shock in the pediatric intensive care unit of Children's Hospital Medical Centre
Salmanzadeh S,Kadivar M
Tehran University Medical Journal , 1999,
Abstract: Sepsis is the systemic response to severe infection in critically ill patients. Sepsis, septic syndrome & septic shock represent the increasingly severe stages of the same disease. Despite the remarkable improvements in outcome, sepsis & septic shock remain an important cause of morbidity & mortality in children. This is a retrospective study among the patients who were admitted in the pediatric intensive care unit (PICU) of Children's Hospital Medical Center from Farvardin 1371 till Esfand 1375. During this period 4018 children were admitted in the PICU, 138 of these patients (3.4%) had the initial diagnosis of sepsis or septic shock. The age of these patients were from 3 months to 14 years (mean of 23.5 months). The male to female ratio was 2.1:1. Out of these 138 patients only 16 cases (11.6%) had sepsis and the others (88.4%) had criterias of severe sepsis or septic shock. Multiple Organ Dysfunction (MOD) were found in 96 cases (69.3%). Diarrhea was the most common primary disease that resulted in sepsis or septic shock. Only 20.3% of the cultures were positive, among which E-Coli was the most in 8.7%, Staphylococcus aureus in 5.7%, Klebsiella in 2.9% and pseudomonas in 1.4%. 66.7% of these patients expired, the mortality rates of the patients with severe sepsis or septic shock that concommitantely had MOD were higher than the other (P<0.0005). So it may be better if children with clinical diagnosis of sepsis be hospitalized in an intensive care unit or at minimum in a facility that can closely monitor these patients during the initial stabilization period.
Evaluation of a Novel System for Rapid Antibacterial Susceptibility Testing
S Salmanzadeh-Ahrabi,Gh-R Irajian,S Ercis,T Kocag?z
Iranian Journal of Public Health , 2007,
Abstract: Early determination of antibacterial susceptibility increases the success of therapy, decreases unnecessary use of antibacterial agents and side-effects, and lowers the overall healthcare cost. We have evaluated a rapid antibacterial susceptibility test, Qui-Sensitest (Salubris Inc., Istanbul, Turkey), which is based on a rapid culture medium that indicates growth by changing its color. Qui-Sensitest proved to be a reliable rapid test for determining antibacterial susceptibility having an overall agreement of 97.6% with Kirby Bauer disk diffusion test results for enteric bacteria with 0.4% of major discrepancies and 2.0% of minor discrepancy. Since the test makes the results available in 3.5-6 hours, it can provide the means for choosing the right treatment regimen the same day the infectious agent is isolated.

Jundishapur Journal of Microbiology , 2012,
Abstract: Background: Approximately 1.8 million of the world’s population is infected with both M.tuberculosis (TB) and HIV. HIV-seropositive patients with TB may have radiographically atypical presentations.Objectives: This study aimed to determine whether there was any difference in radiological presentation of pulmonary TB between HIV-seropositive and HIV-seronegative patients.Patients and Methods: Information on 204 patients who were admitted with a diagnosis of pulmonary TB to the infectious ward of Razi Hospital, Ahvaz, between 2004 and 2008 was obtained from their records. They were divided into HIV-seropositive and HIV-seronegative groups. All clinical signs and symptoms and radiological findings were extracted from each patient file and recorded in a questionnaire.Results: Normal thoracic radiography, pleural effusion, milliary pattern, and hilar and mediastinal lymphadenopathy were more common in the HIV-seropositive group. Pulmonary infiltration and cavitary lesions in Chest X-ray (CXR) were more frequent in the HIV-seronegative group. The prevalence of fibrosis in HIV-seronegative patients was higher than in HIV-seropositive subjects. Upper lobe pulmonary involvement in HIV-seropositive patients was less frequent than HIV-seronegative persons due to their immunodeficiency.Conclusions: Radiological presentation of pulmonary TB differs between HIV-seropositive and HIV-seronegative patients due to progressive immunodeficiency from HIV infection.
Extension Methods and Organizational Characteristics for Supporting Sustainable Water Resource Management in Agriculture of Iran
A.R. Ommani,M. Chizari,C. Salmanzadeh,J.F. Hossaini
Journal of Applied Sciences , 2009,
Abstract: The primary purpose of this research was to identify extension methods and organizational characteristics for supporting Sustainable Water Resource Management (SWRM) in agriculture of Iran. The total population of agricultural extension experts (N = 110) of Agricultural-Jihad Organization of Khuzestan Province of Iran considered as population of study. A mailed questionnaire was used to collect the data. The response rate of questionnaire was 78% (N = 86). Appropriate descriptive statistics such as mean scores, standard deviations and correlation coefficient were used. The findings show that extension experts had positive perceptions about SWRM in agriculture. Extension experts believed that among extension methods, on-farm education, problem solving methods and workshop had very high importance for supporting SWRM in agriculture. Also, ranking based on the perceptions of extension experts indicated that the three most important organizational characteristics of extension system for supporting SWRM in agriculture were: considering local groups, participatory management and considering job qualification. It is concluded that appropriate extension methods and organizational characteristics for supporting SWRM needs to be accurately implemented for the extension system development.
Study of the Structural and Electrical Properties of Cr-Doped BiFeO3 Ceramic  [PDF]
S. S. Arafat, S. Ibrahim
Materials Sciences and Applications (MSA) , 2017, DOI: 10.4236/msa.2017.810051
Abstract: Multiferroic BiFe1-xCrxO3 (x = 0.2 and 0.4) ceramics were synthesized in a single phase. The effects of Cr3+ substitution on the crystal structure, dielectric permittivity and leakage current were investigated. Preliminary X-ray structural studies revealed that the samples had a rhombohedral perovskite crystal structure. The dielectric constant ε' significantly increased while the dielectric loss tanδ was substantially decreased with the increase in Cr3+ substitution. The temperature effect on the dielectric properties exhibited an anomaly corresponding to magneto-electric coupling in the samples and was shifted to lower temperatures with the increase in Cr3+ substitution. The leakage current density also reduced in magnitude with the increase in the Cr3+ substitution.

Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.66086
Abstract: Let \"\" be an injective function. For a vertex labeling f, the induced edge labeling \"\" is defined by, \"\" or \"\"; then, the edge labels are distinct and are from \"\". Then f is called a root square mean labeling of G. In this paper, we prove root square mean labeling of some degree splitting graphs.
A Parameter Estimation Model of G-CSF: Mathematical Model of Cyclical Neutropenia  [PDF]

American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.21002
Abstract: We investigate the FFT (Fast Fourier Transform) model and G-CSF (granulocyte colony-stimulating factor) treatment of CN (Cyclical Neutropenia). We collect grey collies and normal dog’s data from CN and analyze the G-CSF treatment. The model develops the dynamics of circulating blood cells before and after the G-CSF treatment. This is quite natural and useful for the collection of laboratory data for investigation. The proposed interventions are practical. This reduces the quantity of G-CSF required for potential maintenance. This model gives us good result in treatment. The changes would be practical and reduce the risk side as well as the cost of treatment in G-CSF.

Fuzzy Based Intelligent Monitoring of Critical Lines in the Restructured Power Market  [PDF]
S. Rajasekaran, S. Sathiyamoorthy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79191
Abstract: Restructured electric market environment allows the power wheeling transactions between the power producers and customers to meet the growing load demand. This will lead to the possible of congestion in the transmission lines. The possible contingencies of power components further worsen the scenario. This paper describes the methodology for the identification of critical transmission line by computing the real power and reactive power performance indices. It also demonstrates the importance of fuzzy logic technique used to rank the transmission lines according to the severity and demonstrated on IEEE-30 bus system.
