BACKGROUND: Serologic markers are used to screen and diagnose the hepatitis B virus infection. In endemic area of hepatitis B, the coexistence of HBsAg and anti-HBs was frequently observed. This finding is unusual and difficult to interpret. In this study, we performed three molecular biologic assays-polymerase chain reaction (PCR), chemiluminescent molecular hybridization assay (CMHA), branched DNA (bDNA) nucleic acid hybridization assay- to detect HBV-DNA in the sera which showed both HBsAg and anti-HBs positivity. To define the patients` exact clinical conditions, we analysed the characteristics of the patients according to their diagnoses, other serologic markers and clinical findings. METHODS: HBsAg and anti-HBs were detected by EIA (Enzygnost, Behringwerke, Germany) from clinical specimens of Yonsei University College of Medicine Severance Hospital collected In the period between January 1996 and December 1996. Eighty three specimens from Severance Hospital and twenty two specimens from Health Care Center were randomly selected and were subjected to HBV PCR, HBV CMHA and HBV bDNA assay for the presence of HBV-DNA. RESULTS: The patients were arbitrarily divided into 4 groups on the basis of the optical density values of enzyme immunoassay results. Group I (high HBsAg and high antral-HBs) consisted of 6 cases; group II (high HBsAg and low anti-HBs) consisted of 70 cases, group III (low HBsAg and high anti-HBs) consisted of 1 case; group IV (low HBsAg and low antral-HBs) consisted of 6 cases. Among 83 cases, the positive rate was 51.8% (43 cases) using PCR method, 53.0% (44 cases) using CMHA, 60.2% (50 cases) using bDNA assay. HBeAg and anti-HBc IgM were helpful to predict the presence of HBV-DNA in the sera. CONCLUSIONS: More than half of the patients who showed both HBsAg and anti-HBs positivity were positive for HBV-DNA by molecular biologic methods. In contrast, no one whose serologic markers with only anti-HBc positivity with out HBsAg and anti-HBs positivity showed HBV-DNA positive in the sera from Health Care Center. Taken together, the management and follow-up of the patients of both HBsAg and anti-HBs positivity could be greatly aided by combined adoption of any one molecular biologic assay of HBY-DNA with other serologic markers such as HBeAg and anti-HBc IgM.

BACKGROUND: The self-inflating bag-valve resuscitator is an useful breathing support equipment in the cardiopulmonary resuscitation, the transportation of patients who required ventilation assist, or respiratory therapy. The inspiratory oxygen concentration (FiO2) or tidal volume (VT) delivered to the patient depends on various conditions during bag-valve ventilation. METHODS: During bag-valve ventilation without a reservoir at oxygen flow rates of 10 l/min, we evaluated fifty six volunteers to determine the FiO2 and VT at ventilatory frequencies of 10, 12 and 15 cycles per minute and to observe the effect of hand size and grasp power on FiO2 and VT in two-hand compression methods. RESULT: The FiO2 at frequency of 10 cycles/min were 50.1% and it was higher than other ventilatory frequencies. However, the VT was not statistically different among the changes of ventilatory frequency. In the change of VT according to characteristics of the hand, the operator's hand size exerted influence on VT(larger vs. smaller ; 942ml vs. 885ml, p<0.05), but the grasp power of the hand did not significantly affect. Separate analyses with size or grasp power of the hand failed to reveal significant differences of the FiO2. CONCLUSION: The results suggest that a slowing of ventilatory frequency within the allowable ranges for adequate gas exchange increase the FiO2 during bag-valve ventilation without reservoir, and that hand size may exert influence on the VT without FiO2 changes but grasp power may not be a contributing factor to the VT or FiO2 changes.
