background: helicobacter pylori is the cause of serious diseases including gastric cancer and gastric mucosa–associated lymphoid tissue lymphoma.50% of world population is infected by this microorganism and it -based on epidemiologic studies - is mainly acquired during childhood . there is not enough evidence about prevalence of this infection in children and its risk factors so encourage us to...

Echinococcus is endemic in some parts of the world but cardiac involvement with hydatid cyst is rare. Here, we report a 55-year-old man who developed right ulnar fracture and was scheduled for surgery. During routine preoperative evaluation abnormal findings in ECG were found. In echocardiography, a large mass was detected in the inferior wall of the left ventricle. Coronary angiography showed ...

No prospective data exist on the risk of microbiologically confirmed urinary tract infection (UTI) and asymptomatic bacteriuria (AB) in relation to diabetes mellitus and its characteristics. The authors prospectively (1998-2002) followed 218 diabetic and 799 nondiabetic Washington State women aged 55-75 years for UTI and AB. The baseline examination and two annual follow-up examinations include...

Urinary tract infection (UTI), which may be symptomatic or asymptomatic, is one of the most common bacterial infections requiring medical treatment during pregnancy.1 Asymptomatic bacteriuria (ASB) affects 2-10% of pregnant women, depending on the patient population. If left untreated, as many as 30-50% will develop symptomatic UTI, often in the form of pyelonephritis.2 The hormonal and mechani...

From October 1999 to July 2001, a prospective cohort study was conducted to assess the intestinal Escherichia coli population dynamics of 23 sexually active couples. We tested the hypothesis that intestinal persistence and predominance of specific E. coli strains, co-colonization of sex partners with the same E. coli strain, and the intestinal diversity of fecal E. coli, contribute to recurrent...

BACKGROUND During the 2009 pandemic influenza H1N1 (2009) virus (pH1N1) outbreak, school students were at an increased risk of infection by the pH1N1 virus. However, the estimation of the attack rate showed significant variability. METHODS Two school outbreaks were investigated in this study. A questionnaire was designed to collect information by interview. Throat samples were collected from ...

OBJECTIVES This study was performed to investigate the mumps transmission control status and inapparent infection rate among middle and high school students in Daegu City during a mumps outbreak. METHODS Nine schools (two middle schools and seven high schools), which reported a number of mumps cases between 2007 and 2008 were selected for investigation. During March-May 2008, a standard quest...

Current estimates of antiviral effectiveness for influenza are based on the existing strains of the virus. Should a pandemic strain emerge, strain-specific estimates will be required as early as possible to ensure that antiviral stockpiles are used optimally and to compare the benefits of using antivirals as prophylaxis or to treat cases. We present a method to measure antiviral effectiveness u...

asymptomatic malaria (asm) has been implicated in the development of hemolytic crisis in infected sickle cell anemia (sca) patients worldwide. this study surveyed steady state sca nigerian patients for asm to investigate the influence of malaria prevention behaviors and age on parasitaemia and multiplicity of infection (moi). a total of 78 steady sca patients aged 5 – 27 years on routine care a...

conclusions: the most common infectious episode among spinal cord injury patients was found to be urinary tract ınfection. e. coli was the most common microorganism isolated from urine samples. antibiotic use in the previous 2 weeks or 3 months, hospitalization during the last one-year and previous diagnosis of urinary tract ınfection were the risk factors identified for the development of infe...
