BACKGROUND: Infiltration of eosinophils and activated T cells into the airway is a characteristic feature of allergic inflammation such as asthma. IL-4 has been shown to mediate adhesion of eosinophils and T cells to endothelial cells by inducing VCAM-1 expression on endothelial surface. IL-13 shares a number of biologic properties with IL-4. OBJECTIVE: We aimed to investigate the effects of IL-13 on the adhesion of eosinophils to human umbilical vein endothelial cells (HUVEC) and on the expression of VCAM-1 in HUVEC. METHOD: HUVEC was incubated for 24h with IL-13 (10ng/ml), IL-4 (10ng/ml) and TNF-a (10ng/ml). Surface expression of VCAM-1 in HUVEC was detected using irnmuno-cytochemical stain and reverse transcription-polymearse chain reaction (RT-PCR), and the adhesion of eosinophils to HUVEC was quantitated using eosinophil peroxidase (EPO) assay. RESULTS: The VCAM-1 expression on IL-13-treated HUVEC increased more than in the expression on medium-treated HUVEC (p<0.05). The adhesion of eosinophil to IL-13- treated HUVEC also increased more than in the adhesion to medium-treated HUVEC (p<0.05). The VCAM-1 expression was synergistically induced by TNF-a and IL-13 (p<0.05). IL-13 induced VCAM-1 expression and adhesion of eosinophils to HUVEC, similar to IL-4. IL-13 also induced VCAM-1 mRNA expression, with greater expression than with medium and TNF-a(p<0.05). IL-13-induced surface VCAM-1 was associated with expression of mRNA transcripts and adhesion of eosinophils to HUVEC(r=0.89, r=0.93, p<0.05). CONCLUSION: These findings demonstrate that IL-13 stimulates HUVEC to express surface VCAM-1 and has a possible role in promoting VCAM-1/VLA-4 dependent accumulation of eosinophils during allergic and other inflammatory responses.

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

The purpose of this study is to make an emphasis the necessity of the dynamization after interlocking intramedullary nailing. We reviewed 75 cases of the fractures of the shaft of femur or tibia fixed with static interlocking intramedullary nailing. We excluded the cases in whom the locking screws were removed for the purpose of the relief of pain from the irriataion by those screws. The parameter we reviewed were the type of fracture, postoperative gap between the major fragments. Early callus formation, the union time, postoperative dynamization and controlled weight bearing. In those cases in which the contact surface between the major fragments was more than 50% and there noticed no early callus within 6 weeks after operation, the union time was shortened after dynamization, when the contact surface was less than 50% and there noticed no early callus, the union time was shortened after bone graft and dynamization which resulted in some shortening in the length in acceptable ranges. In cases with a major gap of more than 2mm, the union time was shortened after dynamization. The rate of early callus formation was a little higher in cases with postoperative controlled weight bearing than those to whom we did not permit a controlled weight bearing.

We retrospectively evaluated datas on 61 cases of neonatal sepsis confirmed by clinical symptoms and blood cultures at the NICU of Gil general hospital From Mar. 1989, to Fed. 1992. The results obtained were as follows: 1) The mean gestational age was 32.7+/-2.6 Weeks in preterm infants, and 39+/-1.5 weels on term infants. The mean birth weight was 1,701.4+/-422.4 g in preterm infants, and 3,232+/-581.7 g in term infants. 2) There were 61 infants with neonatal sepsis identified among 13, 486 live births, resulting in an incidence of 0.45%. The sex ratio of male to female was 1.2:1. The incidencdence was higher in preterm infants (2.21%) than in term infants (0.27%). 3) The most commom presenting symptoms of neonatal sepsis were apnea and bradycardia (53.6%) in preterm infants, jaundice (33.3%) in term infants 4) The concurrent diseases in neonatal sepsis were urinary tract infection (UT)(25%), pneumonia (21%), hyaline membrane disease (21%) in the order of frequency. Hyaline membrane disease (33.3%) was the most frequently associated disease in preterm infants, UTI (41.4%) in term infants 5) Gram positive organisms were isolated in 33 casess (52%), gram negative organisms in 30 cases (48%). The most common ortanism isolated from blood cultures was CONS (28.6%). The more common organisms in preterm infants were CONS (26.7%), Enterococcus (23.3%) and Klebsiella (10%). CONS (30.3%), E. Coli (27.3%) and Staphylococcus aureus (12%) were more frequent in term infants. 6) The significant diagnostic laboratory findings for neonatal sepsis were leukopenia ( < or =5000), I:T 0.16, thrombocytopenia ( <150,000/mm3), CRP> or =1+.2 or more of abnormal hematologic values were significantly more frequent in preterm infants (P< 0.05). 7) The risk factors associated with neonatal sepsis were endotracheal intubation (57%), birth ashyxia (Apgar score< or =6 at 5 min.)(39%) and umbilical catheterization (35.7%) in preterm infants, while endotrachial intubation (12.1%), birth ashyxia (12.1%) and premature rupture of membrane ( > or =24hrs)(9.0%) in term infants. 8) Early onset neonatal sepsis (72< or =hr of age) was found in 40 cases (65.6%). 9) The overall mortality rate of neonatal sepsis was 26.0%(39,3% in preterm infants, 15.2% in term infants). The mortality rate was significantly high in pseudomonas infection. 10) In low birth weight infants, the susceptibility to neonatal sepsis was greatest in the infants of lowest birth weight (1,00-1,500 gm) and the mortality rate was inversely proportional to birth weight. 11) Sensitivity to antibiotics in gram postitive organisms were chlorampjenicol (37%), Erythromycin (29%), ampicillin (26%) and cephalothin (26%). It clearly showed that newer antibiotics such as vancomycin is neccessary. In cases of gram negative organisms, sensitivity to antibiotics were amikacin (85%), gentamicin (65%), tobramycin (58%) and cephalothin (54%).

Newborn premature babies have lwo levels of transplacentally acquired maternal immunoglobulin which is mostly transferred after 32~34 weeks gestaton, therefore they may have IgG deficiencies that increase their susceptibility to bacterial infection. We performed this study to determine whether intravenous immunoglobulin (IVIG) therapy improves mortality or infection occurrance rate. From 1 october 1991 to 31 July 1992, 73premature newborn infants with gestational age< or =34weeks were enrolled: the theatment group, consisting of 43infants who received prophylactic intravenous immunoglobulin therapy (500mg/kg/week) and the control group, consisting of 30infants who did not receive. prophylactic intravenous administration of immunoglobulin to preterm infants with a gestational ageage< or =34week, at a dose of 500mg/kg/week, results in maintenance of a satisfactory serum IgG level throughout the high-risk period for infection. But the incidence rates of proven or very probable sepsis, mortality for sepsis and total mortality in the infants receiving intravenous immunoglobulin were not significant differences when compared with those in the control infants. No adverse effects were noted after immunoglobulin transfusions in our subjects. In conclusion, our study does not show any decrease in bacterial infection rate or in mortality rate, and no study in the literature has shown absolute proof of the prophylactic efficacy of IVIG in premature newborns. Larger studies are necessary to confirm these observations and to determine more effective dosing schedules and the optimal levels of orhanism-spectific antibodies. And specific hyperimmnue of monoclonal antibody preparations may be required to provide reliable sources of effective prophylactic to premature neonate with high risk in bacterial sepsis.

BACKGROUND: In order to reduce the diagnostic window period between the time of human immunodeficiency virus (HIV) infection and serological diagnosis, new fourth generation screening assays which detect HIV p24 antigen and specific antibody simultaneously have been developed. In this study, we evaluated the performance of a new fourth generation assay. METHODS: We compared a new fourth generation assay, Architect HIV Ag/Ab combo, with another fourth generation assay AxSYM HIV Ag/Ab combo and a third generation assay, AxSYM HIV 1/2 gO for their performance. The assays were evaluated using 3 HIV seroconversion panels, 305 sera of healthy subjects and 100 sera of patients with HBsAg or anti-HCV antibodies. Within-run and total coefficient variations of the three screening assays were analyzed for the evaluation of precision. RESULTS: Architect HIV Ag/Ab combo shortened the window period by 8.7+/-2.1 days relative to AxSYM HIV 1/2 gO and 2.0+/-2.0 days relative to AxSYM HIV Ag/Ab combo in seroconversion panels. Architect HIV Ag/Ab combo presented the best performance in precision among the three reagents; total CV for positive control was 3.6%, 9.6% and 4.6% for Architect HIV Ag/Ab combo, AxSYM HIV Ag/Ab combo and AxSYM HIV 1/2 gO, respectively. Specificities of three assays were not different in this study. CONCLUSIONS: HIV Ag/Ab combined assays reduced the diagnostic window as compared to the third generation screening assays, enabling an earlier diagnosis of HIV infection. A new fourth generation assay, Architect HIV Ag/Ab combo presents a better performance than AxSYM HIV Ag/Ab combo, showing improved seroconversion sensitivity and precision.
