Question: Can nonpharmacological methods be used for neonatal pain management. Finding: Nonpharmacological methods like Sucrose, breastfeeding etc have shown to significantly reduce the pain caused by intramuscular hepatitis B vaccination. Meaning: Nonpharmacological methods are the safe and cheap potential modalities of analgesia which can be used during mild to moderate pain in newborns. |
Background: The seropositivity rate of hepatitis B surface antigen (anti-HBs) antibodies is known to be ≥95% after hepatitis B virus vaccination during infancy. However, a low level or absence of anti-HBs in healthy children is discovered in many cases. Recent studies in adults reported that a reduced anti-HBs production rate is related to obesity.
Purpose: To investigate whether body mass index... |
Purpose : This study aimed to identify the true extent of non-responsiveness in full-term infants born from HBsAg-negative or HBsAg-positive mothers and vaccinated against hepatitis B virus (HBV) at 0, 1, and 6 months of age and to evaluate the effect of revaccination among non-responders. Methods : The study included 716 full-term infants born in 2004-2007. Of 716, 662 infants... |
Korea is now classified as an area of intermediate endemicity for hepatitis B virus (HBV), due to the implementation of universal HBV vaccination and national preventive programs for HBV infection. A national program of HBV vaccination was launched in Korea in 1988 for school-going children and was listed on a vaccination guideline in 1991. In 1995, universal vaccination for newborn... |
Interferon (IFN) alpha has been the first line therapy of chronic hepatitis B in children, but HBeAg seroconversion occurred in 26% of treated children compared to 11% of controls in multinational randomized controlled study. Recently, lamivudine was shown to be a potent inhibitor of Hepatitis B virus (HBV) reproduction both in HBeAg positive and in HBeAg negative (the pre-core mutant... |
Purpose : Perinatal hepatitis B viral infection is decreasing; however, 10% of babies to HBeAg positive mothers still become chronic carriers despite perinatal prophylaxis. Although, the cause of prophylaxis failure is still unclear, an importance of maternal HBV-DNA level at the delivery time has been suggested. This study was established to certify if it would be a useful predictable factor... |

The generation of a draft sequence of the human genome has lead to an opportunity to characterize human diversity, including the differences in host response to numerous pathogens. Host responses upon exposure to a pathogen can determine the wide spectrum of illness from subclinical or mild to severe diseases. Host factors, particularly genetic backgrounds, influence the pathogenesis of infectious diseases.... |

They were followed between... |
Perinatal hepatitis B virus(HBV) infection may occur despite combined immunoprophylaxis with hepatitis B immunoglobulin and vaccines. Although the mechanism of perinatal prophylaxis still has been obscure, it could be due to : in utero infection; host factors as the personal immunological differences of HLA or cytokine gene; viral factors as a high maternal HBV-DNA level or the presence of surface... |

Purpose : The envelope of HBV consists of three polypeptides which are encoded in pre-S/S open reading frame. Three translation initiation sites are present within this pre-S/S open reading frame, i.e. pre-S1, pre-S2, and S, allowing the expression of large, middle and small HBs proteins. The pre-S1 is thought to carry the receptor binding site for viral entry into hepatocyte... |
