Of the first 250 heart and 41 heart-lung transplant recipients in the Papworth series, 244 who survived for longer than one month after transplantation were studied for evidence of cytomegalovirus (CMV) infection by serological methods. Overall, 43 (17.6%) patients acquired primary CMV infection and 76 (31.1%) had evidence of CMV reactivation or reinfection. The source of CMV infection was foun...

This paper investigates the relation between immunity and hardness in exponential time. The idea that these concepts are related originated in computability theory where it led to Post’s program, and it has been continued successfully in complexity theory [9, 13, 20]. We study three notions of immunity for exponential time. An infinite set A is called • EXP-immune, if it does not contain an inf...

Hemophilia is the most common congenital coagulative disorder which exposes the patients to many problems because of lack of coagulative factors, higher risk of viral infections and other complications. This study was designed to detect the prevalence of hepatitis B and C infection in hemophiliac patients referring to Kerman Samenalhojaj Center. For this purpose, 97 hemophiliac patients were st...

Background: Approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis B virus infection. Ten different hepatitis B virus genotypes have been identified with distinct geographical distributions. Different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...

BACKGROUND Screening for hepatitis B virus (HBV) infection in pregnant women to identify newborns who will require prophylaxis against perinatal infection is a well-established, evidence-based standard of current medical practice. In 2004, the U.S. Preventive Services Task Force (USPSTF) recommended universal screening of pregnant women for HBV infection at the first prenatal visit. PURPOSE T...

conclusions the palestinian and israeli official policies to give a booster dose for risk groups like medical students at anti-hbs level below 10 miu/ml should continue to ensure absolute protection. the currently-used vaccine and its time program cleared virus from students believed to have been exposed to the virus during their lifetime. background hepatitis b infection is a global public hea...

Background. Ninety-percent of perinatal hepatitis B virus (HBV) infection results in chronic HBV which usually is asymptomatic, but carries a 25% risk of premature death from progressive liver injury, cirrhosis, and liver cancer. In 1990, the Centers for Disease Control and Prevention (CDC) funded the Perinatal Hepatitis B Prevention Program (PHBPP) to accelerate elimination of perinatal HBV tr...

It has been suggested that Asian patients have reduced survival after liver transplantation because of greater recurrence of hepatitis B virus (HBV). We analyzed the outcome of Asian and non-Asian patients receiving transplants for chronic hepatitis B between May 1988 and March 1994. Baseline Child-Pugh score and United Network for Organ Sharing (UNOS) status, HBV recurrence, and survival were ...

There are no standard guidelines to follow when a patient with chronic hepatitis B infection becomes pregnant or desires pregnancy. Topics to consider include which patients to treat, when to start treatment, what treatment to use and when to stop treatment. Without any prophylaxis or antiviral therapy, a hepatitis B surface antigen and E antigen positive mother has up to a 90% likelihood of ve...
