Background & Aims: Hemophilia A is a common disorder of blood coagulation caused by deficiency of factor VIII with X-linked recessive inheritance affecting approximately 1 in 5000-10,000 male births worldwide. Hemophilia A caused by a heterogeneous spectrum of molecular defects in factor VIII gene .The most common mutation is the intron 22 inversion which can be analyzed by several methods, such as; Southern blotting , LD PCR or IS-PCR. This study aimed to identify the prevalence of intron 2...

Although musculoskeletal symptoms (MSS) are common worldwide, little is known about its prevalence amongst the working population in relation to gender, age, and occupational/industrial group. This paper describes the prevalence of MSS in a sample of 3003 men and women aged 20–64 randomly selected from the New Zealand Electoral Roll. MSS experienced during the previous 12 months in 10 body regions was assessed in telephone interviews using a modified version of the Nordic Musculoskeletal Q...

The abundance, diversity, and distribution of biodegradation genes (BDGs) and phenol degradation genes (PDGs) in activated sludge (AS) from two wastewater treatment plants (WWTPs) at different sampling times were assessed by metagenomic analysis using a total of 15 datasets derived from Illumina high-throughput sequencing and BLAST comparisons to BDGs and PDGs databases. The results showed that the abundance (0.015–0.030%) and diversity of BDGs in AS varied with the WWTP and the sampling t...

Introduction and objectives: The on-the-road driving test in normal traffic is applied to examine the impact of drugs on driving performance. Although participants are accompanied by a licensed driving instructor, under Dutch law, the driver is primarily responsible for safe driving and is not permitted to continue driving when it is judged that the drug compromises safety. This review examined the prevalence and nature of stopped driving tests, and the relationship with Standard Deviation ...

 The proportion of motor vehicle crashes that involve a drowsy driver likely is greater than existing crash databases reflect, due to the possibility that some drivers whose pre-crash state of attention was unknown may have been drowsy. This study estimated the proportion of crashes that involved a drowsy driver in a representative sample of 47,597 crashes in the United States from 1999 through 2008 that involved a passenger vehicle that was towed from the scene. Multiple imputation was use...

 Celiac disease (CD) may be misdiagnosed as Irritable Bowel Syndrome (IBS) resulting in long delays in diagnosing CD. There are contradictory reports on the association of CD with IBS. Appropriateness of screening all patients with IBS for CD and how to screen them are still under question. In a cross-sectional study, 328 IBS patients (Rome II) referred to the Poursina Hakim Gastroenterology Clinic were investigated for CD. Total serum anti-tissue transglutaminase IgA (anti-tTG IgA) concent...

 Gastroesophageal reflux disease (GERD) is very common in western countries. GERD is increasing, has profound effects on health economics, disturbs the patient's health-related quality of life, and increases the risk for development of esophageal adenocarcinoma. GERD is considered to be infrequent in developing countries. This study was performed to determine the prevalence of GERD among Iranians. Major GERD symptoms (heartburn and acid regurgitation) were assessed through an interview by t...

Background: Population screening for FMR1 mutations has been a topic of considerable discussion since the FMR1gene was identified in 1991. Advances in understanding the molecular basis of fragile X syndrome (FXS) and ingenetic testing methods have led to new, less expensive methodology to use for large screening endeavors. A core criterion for newborn screening is an accurate understanding of the public health burden of a disease,considering both disease severity and prevalence rate. This a...
