Context: Although cholelithiasis is not a common condition in children, recent studies have documented an increasing incidence rate, owing to the development of diagnostic tools. The prevalence of cholelithiasis in children has been reported to be 0.13% -0.3%, whereas in obese children and adolescents, the prevalence rate has been estimated at 2% -6.1%. In this study, we aimed to review cholelithiasis in children. The gathered results could be useful in finding a suitable method and proper clinical practice for this complication.Evidence Acquisition: For literature review, international databases, including PubMed and Google Scholar, were searched, using keyword combinations, e.g., "cholelithiasis in children", "gallstone in children", and "childhood cholelithiasis", to review diagnostic and therapeutic approaches for cholelithiasis in children from 2006 to 2016. Also, some articles were retrieved through hand searching and reviewing the reference lists of papers, regardless of the date of publication. Abstracts, duplicates, and articles irrelevant to childhood cholelithiasis were excluded.Results: A total of 36 out of 93 articles were reviewed. The results showed that the prevalence of childhood cholelithiasis varies in different communities, with a global rate of 1.9%. Most cases of cholelithiasis in children were associated with underlying diseases. Hemolytic diseases, hereditary blood disorders, and cirrhosis were among the main causes of cholelithiasis in children. Cholelithiasis was detected incidentally or via diagnostic evaluations due to the presentation of symptoms. Conclusions:Although evaluation of the underlying causes of gallstone formation and appropriate diagnostic/therapeutic implications is still a challenging issue in the management of childhood cholelithiasis, in asymptomatic cases or those with gallstones of certain sizes, it is only recommended to monitor the disease or rule out the underlying causes. It should be noted that long periods of diagnostic and therapeutic approaches can impose stress and tension on families.

The heavy casualties associated with mass disasters necessitate substantial resources to be managed. The unexpectedly violent nature of such occurrences usually remains a problematic amount of victims that urgently require to be identified by a reliable and economical method. Conventional identification methods are inefficient in many cases such as plane crashes and fire accidents that have damaged the macrobiometric features such as fingerprints or faces. An appropriate recognition method for such cases should use features more resistant to destruction. Forensic dentistry provides the most appropriate available method for the successful identification of victims using careful techniques and precise data interpretation. Since bones and teeth are the most persistent parts of the demolished bodies in sudden mass disasters, scanning and radiographs are unrepeatable parts of forensic dentistry. Forensic dentistry as a scientific method of human remain identification has been considerably referred to be efficient in disasters. Forensic dentistry can be used for either “sex and age estimation,” “Medical biotechnology techniques,” or “identification with dental records,” etc. The present review is aimed at discussing the development and implementation of forensic dentistry methods for human identification. For this object, the literature from the last decade has been searched for the innovations in forensic dentistry for human identification based on the PubMed database.

A new sugarcane leaf spot disease caused by Exserohilum rostratum was found in Ahvaz, southwestern Iran during a series of surveys on fungal species causing sugarcane leaf diseases in 2011. Three single spore derived isolates were obtained from diseased sugarcane leaves and the pathogenicity of each isolate to sugarcane plants was confirmed by inoculation tests based on Koch's postulates. The isolates were identified as members of E. rostratum based on their morphological characters as well as rDNA-ITS (internal transcribed spacer) sequences. This is the first report of leaf blight caused by E. rostratum on S. officinarum in Iran.

Context: The association between periodontal disease (PD) and cardiovascular disease (CVD) has been evaluated in many epidemiological studies; however, the results are controversial. Herein, we aimed to review if the childhood periodontal diseases are associated with future cardiovascular events or not.
