[Effect of education workshop on interns' knowledge of childhood nutrition and growth monitoring in Qazvin Medical School]

This interventional study was carried out to determine the effect of education workshop on interns' knowledge of Qazvin Medical School over childhood nutrition and growth monitoring in 2003-2004. All medical trainees [191] doing their health course on childhood nutrition and growth monitoring were selected. Data were collected using a questionnaire and analyzed by Macnemar test. Based on results obtained in the present study, while 6.8% of interns were classified as having good knowledge before taking part in education workshop it reached to 63.9% after intervention [P<0.05].Furthermore, the two other groups of participants initially categorized as having intermediate [30.9%] and poor [62.3%] knowledge before the intervention decreased to 28.2% and 7.9%, respectively [P<0.05]. Results from this study emphasize on the necessity of holding workshop for medical students to promote their knowledge and experience associated with nutrition and growth monitoring chart

[Relationship between DNMT1 gene's SNPs and colorectal cancer at Taleghani hospital in Tehran]

The relation between Single Nucleotide Polymorphisms [SNPs] and a number of diseases has triggered many researches. Investigating the possible relations between SNPs present in DNMT1 gene from man's chromosome 19 and colorectal cancer. This was a case/control study in which 100 patients with colorectal cancer, referred to Research Center of Gastroenterology and Liver Diseases of Shaheed Beheshti Medical University during 2008, were chosen as case group. The control group included an equal number of patients who visited the medical center for a variety of reasons. Genetic test was carried out on all patients to determine the type of 6 SNPs of DNMT1 gene from man's chromosome 19. Data were statistically analyzed by SPSS software using chi-square test and logistic regression. All SNPs investigated showed significant relations with colorectal cancer indicating that in all cases the chance of getting colorectal cancer in people with genotype 1 and 2 was much higher than those with genotype 0. by exploring people's SNPs, it is feasible to predict the risk of catching colorectal cancer and thus establishing proper preventive measures

[Correlation between anti-HBs antibody level with education status and duration of practice among dentists in Qazvin city]

Hepatitis B virus [HBV] is one of the main causes of chronic liver disease and hepatocellular carcinoma. Dentists, surgeons, and dialysis staff, are considered to be at higher risk of HBV compared to other health care providers. The aim of this study was to determine the correlation between anti-HBs level with education status and duration of dental experience among dentists practicing in Qazvin city, Iran. The participants of this analytical-descriptive survey were consisted of all dentists practicing in Qazvin. A questionnaire was used to collection demographic and clinical information. This step was followed by the collection of blood samples. ELISA technique was used for laboratory assessment of serum specimens for HBsAg and anti-HBs antibody titer. SPSS software and Chi-square test were used for data analysis. Out of 77 dentists who completed the questionnaire, 74 [93.7%], including 49 general practitioners [63.6%] and 24 specialists [36.4%] supplied their blood samples. All blood samples were HBsAg negative. A total of 40 general practitioners [81.6%] and 24 specialists [85.7%] had proper vaccination [dosage]. Among all, 34 general practitioners [69.4%] and 12 specialists [24.9%] reported exposure to patients with hepatitis. The antibody level was less than 10 mIU/ml in 8 general practitioners [10.8%], 10-100 mIU/ml in 12 dentists [16.2%], 100-500 mIU/ml in 23 [31.1%] others, and it was more than 500 mIU/ml in 31 dentists. This level was positive [10-500 mIU/ml] in 2 general practitioners [2.7%] that did not have prior vaccination history. There was a significant correlation between antibody level and vaccine dosage [P= 0.04], as well as the education status [general and specialist] [P= 0.03]. There was no significant correlation between antibody level and duration of dental practice. This study showed significant correlation between anti-HBs antibody levels with education status of dentists in Qazvin city. However, we were not able to detect a significant correlation between antibody level and duration of dental practice in this population
