Abstract: 

Background: About 1.9 millions persons from approximately 140 different countries and 94 thousands from Iran come together in Saudi Arabia for the Hajj each year. Regarding to high incidence of respiratory infections symptoms; the serious problems of pilgrims and Hajj medical organizations; in recent years prevention of these symptoms for Hajj programming managers is essential. We performed this study to determine effect of influenza vaccination on incidence of influenza like illness and other respiratory tract infection symptoms among Iranian pilgrims in Hajj 2004.Materials and methods: This research was a cohort study and performed on 406 pilgrims (vaccinated =203 & control=203) of six caravans from Tehran, Qom, Semnan, Mahdishahr and Shahryar. In Hajj period daily, symptoms and physical examination findings of pilgrims phone weekly for one month after comeback to Iran. Data was analyzed by t, mann-withney and chi-square tests.Results: Mean duration of cough, sore throat and nasal congestion in vaccinated group reduced 1.2, 0.5 and 0.4 day respectively. Mean rate of cough incidences reduced from 1.4 to 1.3, headache incidence reduced from 0.8 to 0.7, rhinorrhea incidence from 1.2 to 1, nasal congestion incidence from 1 to 0.8, but only nasal congestion incidence reduction was statistically significant (p<0.02). Cough, sore throat, headache, and nasal congestion severity in vaccinated group were approximately 3 to 7 percent lower than unvaccinated group and these symptoms incidences in vaccinated group were 3 to 9 percent lower than unvaccinated group but only nasal congestion incidence reduction was statistically significant (p<0.05). Finally Influenza like illness symptoms preventive efficacy of influenza vaccine was 20%.Conclusion Influenza vaccine efficacy to prevent influenza like illness among Iranian pilgrims in Hajj 2004 was low. It could be due to i… -04 influenza vaccine.Regarding to socioeconomics aspects, we recommend only high risk groups of pilgrims should be vaccinated.

Abstract: 

Background: Theres a trend toward, using high dose cytarabine as a complementory regimen in post remission phase patients. the use of this regimen in different studies and its lack of use in iranian clinics. made us to design this study to compare the results of high dose cytarabine regimen versus standard high grade dose cytarabine regimen. Materials and Methods: A randomized controlled trial was conducted on 39 patients with AML.Patients with de-novo AML remission with received induction 7+3 regimen. Complete responders to induction therapy were randomized for post remission therapy between HDAC 3 gr/m for 4 days or 7+3 regimen with cytarabin 200 mg/m for 7 days and Dounorobicin at 45 mg/mld for 3 days. Patients with AML (M3) secondary AML or positive myelodysplastic history were excluded. The AML diagnosis was made by aspiration biopsy of the bone marrow and if 50% cellularity and more than 30% myeloblasts were detected in the samples the therapy would have started. Results: 19 out of 39 patients received HDAC and 20 standard 7+3 regimens. With a median follow-up of 36 months there was not significant difference in overall between HDAC and 7+3 regimen. The Survival rate at 24 months was 10% (HDAC) versus 23% (7+3). Disease free Survival (DFS) was 11 months (HDAC) versus 14 months (7+3) and median survival was 14 months (HDAC) versus 19.8 months (7+3).no significant difference between the two groups was detected. Post remission therapy was not associated with a significantly increased risk of hematologic, ocular, hepatic and neurologic toxicity.Conclusion: Although limited, current experience suggests that HDAC regimen maybe a feasible and safe consolidation therapy without significant toxicity. This study did not demonstrate an improvement in survival for HDAC regimen, however, further studies is needed and recommended.

Abstract: 

Background: The hepatitis E virus (HEV) has a global distribution and is known to have caused large waterborne epidemics of icteric hepatitis. Transmission is generally via the fecal oral route. Some reports have suggested parenterally transmission of HEV. Anti-HEV prevalence data among chronic hemodialysis (HD) patients are few and given conflicting results.Materials and Methods: This cross-sectional study was conducted in August of 2004.We tested 324 chronic HD patients attending three different units in the city of Tabriz, in the northwestern part of Iran, for anti-HEV antibody. A specific solid- phase enzyme-linked immunoassay (Diapro, Italy) was used.Results: The overall seroprevalence of hepatitis E was7.4% (95% CI: 4.6%-10.6%).The prevalence rate of HBV and HCV infection were 4.6% (95% CI: 2.3%-6.9%) and 20.4% (95% CI: 16%-24.8%) respectively. The seroprevalence of anti-HEV antibody among chronic HD patients was associated significantly with age. No statistically significant association was observed between HEV seropositivity and other variables. Conclusion: We observed high anti-HEV prevalence; there was no association between HEV and blood borne infections (HBV, HCV, HIV) in our HD patients; most anti -HEV positive patients we found were probably related to a local infection by HEV. This is the first report concerning seroepidemiology of HEV infection in a large cohort of chronic HD individuals in Iran.

Abstract: 

Background: In recent years many studies have investigated the role of nitric oxide (NO) in acute renal failure (ARF). In previous investigation, we studied the effects of NO system on changes in urinary enzyme levels, lactate dehydogenase and alkaline phosphatase in a gentamicin (GM) model of AEF. The preseritstudy was designed to evaluate the effects of NO induction or inhibition on functional and structural changes ingentamicin-induced ARF.Materials and methods: Kidneys from male Sprague-Dawley rats were perused for 90 min in situ. To measure glomerular filtration rate (GFR), inulin was added to the perfusate. Tubular cell toxicities were evaluated by measurement of urinary N- acetyl-  b-d-glucosaminidase (NAG) levels. At the end of the experiments, kidneys were transferred to 10% formalin buffer for fixation. The sections were evaluated for histological changes by light microscopy.Six groups (seven in each group) were studied: 1. Control with no treatment; 2. L-arginine (2 mM in perfusate); 3. Lnitro- arginine-methyl ester (L-NAME, 0.1 mM in perfusate); 4. Gentamicin (0.5 mg/ml in perfusate); 5. GM + Larginine; 6. GM + L-NAME.Results: L-arginine prevented, whereas, L-NAME enhanced GM-induced enzyme release and GFR reduction.Histological studies showed that GM-treated kidneys had clear evidences of tubular damages and these damages were increased by simultaneous administration of L-NAME and GMConclusion: This study suggests that NO may have a protective effect on functional and tructural changes in gentamicin-induced ARF.

Abstract: 

Background: Entrococci induced Nosocomail infections are quite prevalent in Tehran hospitals, which are the most important and also the most prevalent cause of urinary infections among gram positive bacteria. The goals of this study are defining the prevalence of different strains of entrococci in Tehran hospitals and their resistance against commonly used antibiotics against these bacteria.Material and Methods: 339 strains of enterococci from patients of two hospitals in Tehran (labafinejad, shahid chamran hosp) were collected from both in out patients all strains were defined by bacteriologic & PCR tests and their drug resistance to penicillin, ampicillin, ciprofloxacin, nitrofurantoin, imipenem and chloramphenicol were defined using carbibaer method. besides dilutional method was performed to defined MIC of gentamycine, streptomycine (high dose aminoglyside resistant species) and ampicillin (on Ent.faccium spp.) Results: of the 339 entrococcus spp.273, were of faecalis strain (77.5%) and 66 were collected as faecium strain (22.5%). The E. facalis and E.facium isolates in the irresistance to ampicllim (13% versus 76.5%), penicillin (14 versus 95.13%), ciprofloxacin (57% versus 80%), nitrofurantion (17.2% versus 54%), imipenem (3.2% versus 83.3%), and chloramphenicol (4.7% versus 19.6%).All isolates of E. faeclis (n=273) were susceptible to vancomynic. Resistance to vancomycin among isolates of E. faecium (n=66) has increased from 5% in 2001 to 10.6% in 2003, though they remained susceptible to linezolid and guinoprestin/dlfoprestin. The phenotype van A was detected in all vancomycinresistant isolates of E. faecium. The rate of resistance to high level dose of getamaicin (HLGR strains) was high for both species of E. faecalis (42.4%) and E. faecium (60%).Conclusion: The high prevalence of HLGR strains has hindered the use of this antibiotic in synergistic combination with glycopeptides and betalactams. Linezolid and quinopristin dalfopristin could be a potential alternative against multidrug resistant strains of enterococci including glycopeptide resistant isolates in Iran.

Abstract: 

Background: The advantages of breastfeeding are widely documented and in general undisputed. The studies showed different breastfeeding pattern and also there was no information about breastfeeding continuation in the study area. This study was conducted to estimate breastfeeding continuation and its associated factors.Material and methods: An existing data study was carried out to estimate the duration of breastfeeding and its associated factors in Zahedan. 2007 children 2-6 years in Zahedan health centers were studied using health records from 1998 to 2001. Breastfeeding duration and some associated factors such as parents' age, education, and job and child's sex, birth rank, birth weight, and the time of the onset of supplementary feeding were collected.Results: ….  nine percent of women initiated feeding babies with breastfeeding. It was 91.6%, 81.7%, 54.4%, and 2% in the months of 6, 12, 18, and 24 respectively.Breastfeeding related to maternal age, birth rank, birth weight and the timing of the onset of supplementary feeding. There was no relation between breastfeeding and parents' education and job, child sex, and delivery type. During the past four years breastfeeding has dropped off significantly.Conclusion: It is necessary to have planning to maintain and to promote breastfeeding based on modifiable factors.

Abstract: 

Backgrounds: Jaundice is mostly benign, the because of the potential of bilirubin toxicty. Noonates should be monitored carefully for developing severe hyperbilirubinemia. The need to recognize infants who are at risk for significant jaundice apparent in the era of routne early diseharge. The aim of this prospective study is to identify healthy newborns at risk for developing a significant by perbilirubinemia by measuringbilirubin level in eord blood. Methods and materials: Umbilical cord serum bilirubin concentration was analyzed in 643 full term newborns at Mahdieh Hospital. Tehran, Iran, with birth weight> 2500 grams and an Apgar score >7. There were also no signs of eehymosis, cephalohematoma, septicemia, and / or premature rupture of membrane in none of the infants in this study.Bilirubin level was obtained at day three of age and total bilirubin ≥14 mg/dl was defined as significant hyperbilirubinemia. Data have been analyzed using t-test, chisquare, and Receiver Operating Characteristics (ROC) curve.Results: …tatistically significant relation between use of Oxylocin and subsequent. Significant hyperbilirubinemia (p<0.04). 92.4% of neonates with cord bilirubin level below 3 mg/dl would not develop significant hyperbilirubinemia. Cord bilirubin level above 3 mg/dl is not a useful predictor of neonatal jaundiee.Conclusion: Cord bilirubin level cannot identify newborns with subsequent significant hyperhilirubinemia. Rarly diseharged neonates need close follow up and use of any other stratcgice to identify newborns at high risk of jaundiee.
