ABSTRACT
Burns are among the most important accidents related to human health, which receive great attention due to severe complications and high mortality rate. Burn is the fourth leading cause of trauma in the world, and generally divided into three groups, electrical, chemical and thermal. In this a comparison between open and closure dressing in healing and reconstruction of injury was investigated This is a clinical trial study; two hundred burn out patients referred to Motahari hospital were selected and divided into two groups over a period of 16 months from the July 2011 till November 2012.The selected patients had second degree burn with 5.2% extent. Both groups and treated with 1% silver sulfadiazine cream and dressing were made once daily. Duration treatment the healing of each patient was recorded on checklists. Chi-square test and spss were used to analyze the data. Burns from the heat of 170 patients 85%] was greater than the electrical and chemical burns groups. Burn with boiling with 114 cases 57 percent] was the most, compared to electrical and chemical. The mean duration of treatment in open dressing was shorter than closure dressing P <0.001. The results of this study showed that burn with boiling water was the most compared to chemical and electrical. The duration of healing time and hospitalization in open dressing was shorter than closure dressing. It seems to be a preventive program such attention to safety in the home and workplace should be applied
ABSTRACT
Group B streptococcus[GBS][Streptococcus agalactiae] is the leading cause of morbidity and mortality of the newborn infant and accounted as a factor leading septicemia after birth in mothers. Infections in infants are usually acquired by contact with the genital tract of the mother during labor and delivery. So a rapid screening test for group B streptococcus that could accurately identify pregnant women who are carrying the bacteria at the time of delivery would obviate the need for prenatal screening.The goal of this study was molecular epidemiology of group B beta Hemolytic Streptococcal[GBS] colonization in the vaginal flora of pregnant women. Samples were taken from mucus of anal and vaginal of 250 pregnant women during 35-37 week's ingestion by swap. Samples were tested by standard culture using Todd Hewitt Broth and Blood Agar and also by PCR using cfb gene. Culture identified 21[8.4%] women as carriage of GBS from 250 women but PCR assay could identify 24[9/6%] women. In comparison to culture results, sensitivity, NPV Specificity PPV of PCR Were[100%, 100% and 97%, 82%] respectively. The times that used for PCR assay and culture were 2h and 36h respectively. In conclusion, we found that group B streptococci can be detected rapidly and reliably by a PCR assay of combined vaginal and anal secretions from pregnant women at the time of delivery. Also this study shows that incidence of GBS is at high rate in Iranian pregnant woman, so we recommend screening of pregnant woman for detecting of GBS emphatically
