Background and Objective: Dissertations are the most significant documents of the academic curriculum and have an important role in preparing and empowering students to participate in their research activities. This study was conducted to confirm the evaluation of report (thesis) writing in Environmental Health Engineering. Materials and Methods: This descriptive cross-sectional study was conducted on 110 Environmental Health theses in Babol University of Medical Sciences from beginning up to September 2105. The data were gathered by means of citation analysis method using a tailor-made data collection sheet that consisted of 4 parts including general principles, structural principles, writing of references and dissertation content. The data were analyzed with descriptive statistical indexes. Results: Our results showed that the compliance of general criteria in projects had a growing trend during past years. Also, specific criteria from 2010 to 2014 was associated with a trend of steady growth. Compliance of specific criteria has increased from 48. 8% in 2010 to around 86% in 2015. Undefined statistical tests (54. 6%), lack of hypothesis and research questions (34. 5%) and unknown variables (30%) can be mentioned as content defects. Regarding references, 41% of the theses had some mistakes in the sequence of the references and 51. 8% with problems related in style. Totally, 63. 6% of references did not have complete information. Conclusion: Although the majority of theses have been valuable in terms of scientific content, but in structural principles, the dissertation content and the basics of writing references contained numerous errors. Obviously, monitoring can also improve the quality of academic education and research, avoiding waste of resources and achieving a satisfactory result among the students.

Background and Objectives: Urinary tract infection is one of the most common diseases of the urinary tract and is one of the common infections in infants and children. One of the risk factors for urinary tract infection in children is lack of diaper hygiene. Therefore, in the present study, the relationship between diaper hygiene related factors and urinary tract infection in children, was investigated. Methods: This case-control study was performed on 150 children hospitalized in different wards of specialized educational pediatric Hospital. The case group was selected from hospitalized patients with urinary tract infection and the control group from different hospital wards. The data collection tool was a questionnaire consisting of three sections, including: the first part related to the demographic information of mother, the second part was the factors related to the child, and the third part was the factors related to diaper hygiene. Data were analyzed using independent t-test and Chi-square test. Results: In this study, type of child care, income of mother, education level of mother, and type of the diaper (p=0. 001) and time of diaper changing (p<0. 001) were related to developing urinary tract infection. Conclusion: The results of this study showed that the hygiene of diaper could be related to urinary tract infection. Considering the high prevalence of urinary tract infection in children under three years of age, educational interventions are suggested to increase knowledge and preventive behaviors.
