Early Oral Feeding After Surgery for Upper Gastrointestinal Malignancies: A Prospective Cohort Study.

Objectives: Poor nutritional status following abdominal surgeries for esophageal and gastric cancers remains a major challenge in postoperative care. Our study aimed to investigate the efficacy of starting early oral feeding (EOF) in patients undergoing surgical resection of upper gastrointestinal malignancies.

Methods: A total of 180 consecutive patients with a diagnosis of esophageal or gastric malignancies undergoing elective surgical resection between January 2008 and February 2011 were enrolled in this prospective cohort study.

Multiple Sclerosis Presenting as a Delirium: A Case Report.

Objective: To report a case of multiple sclerosis (MS) with delirium as the first presentation.

Clinical Presentation And Intervention: A 34-year-old female was referred to our department with an acute onset of drowsiness, withdrawal from routine activities and aggression, followed by neurologic deficits after a couple of days. Clinical and radiographic examinations were performed, leading to the initial diagnosis of MS.

Hepatitis C virus; its implication for endodontists.

Over 170 million patients worldwide are chronically infected with Hepatitis C virus (HCV); making it a globally important infection. Dentists constantly handle sharp instruments infected with biological fluids and are therefore considered at high-risk of contracting HCV infection. Needle-stick injuries seem to be the most common route of exposure to blood-borne pathogens in dental practice.

Oral conditions associated with hepatitis C virus infection.

Hepatitis C virus (HCV) infection in more than 170 million chronically infected patients with no developed preventive vaccine is a globally important issue. In addition to expected hepatic manifestations, a number of extrahepatic manifestations, such as mixed cryoglobulinemia, glomerulonephritis, polyarteritis nodosa, rashes, renal disease, neuropathy, and lymphoma, have been reported following HCV infection, which are believed to be influenced by the virus or the host immune response. HCV combination therapy with pegylated interferon and ribavirin might be associated with side effects as well.

Medical students' aptitude toward smoking in Warsaw, Strasbourg and Teheran.

Cigarette smoking is a leading cause of preventable death in the world. Medical students play a role in smoking prevention especially as future physicians, but also as role models in society. Their approach, although influenced by medical education, is based on cultural and socio-economic background.

Iranian dental students' knowledge of hepatitis B virus infection and its control practices.

With more than two billion infected people, from whom 350 to 400 million suffer from chronic infection, hepatitis B virus (HBV) is still a major health problem worldwide. As dental treatment puts both dentists and patients at a higher risk of HBV infection, dentists can play an important role in preventing HBV transmission in dental settings. This study was performed to evaluate dental students' awareness and practice regarding HBV-related issues and to compare the results obtained from different academic years.

Optimal duration of treatment for HCV genotype 1 infection in slow responders: a meta-analysis.

Background: A head-to-head comparison of the 72-week and 48-week anti-HCV therapies in slow responders with genotype 1 infection has been performed in several randomized clinical trials (RCTs).

Objectives: This review aimed at summarizing and pooling the results of these studies.

Materials And Methods: RCTs that had evaluated the 72-week vs.

Anti-HBs antibody status and some of its associated factors in dental health care workers in Tehran University of Medical Sciences: Anti-HBs Ab and associated factors in dental society.

Background: Dental health care providers are at risk of infection with hepatitis B virus (HBV). Dentists can occupationally become infected with HBV through needle sticks or exposure to blood and other body fluids.

Objectives: To evaluate anti-HBs antibody titer in students, professors, clinical assistants and non-clinical staff of Faculty of Dentistry, Tehran University of Medical Sciences (TUMS), and to investigate the probable correlation between the level of immunity and a number of associated factors.

Lipid Profiles and Hepatitis C Viral Markers in HCV-Infected Thalassemic Patients.

Background/aims: The distribution of blood lipids, glucose and their determinants in thalassemic patients with chronic hepatitis C virus (HCV) infection has rarely been investigated. Thus, we aimed to investigate the relationship between both liver histologic findings and viral markers and serum lipids in thalassemic patients chronically infected with HCV.

Methods: We enrolled 280 polytransfused thalassemic patients with chronic hepatitis C.

Frequency and antimicrobial susceptibility of Shigella species isolated in Children Medical Center Hospital, Tehran, Iran, 2001-2006.

Appropriate antimicrobial treatment of shigellosis depends on identifying its changing resistance pattern over time. We evaluated 15,255 stool culture submitted from July 2001 to June 2006 to the Laboratory of Children Medical Center Hospital. Specimen culture, bacterial identification, and disk diffusion susceptibility testing were performed according to National Committee for Clinical Laboratory Standards guidelines.
