Abstract
AIM The diagnosis of biliary atresia (BA) is challenging as no single preoperative test is 100% accurate, especially for distinguishing it from other causes of neonatal cholestasis (NC). Intercellular adhesion molecule (ICAM) elevation was reported in BA as a part of the immune-mediated inflammatory process. The use of ICAM-1 as a discriminative tool between BA and other causes of NC has never been addressed before. This study was to evaluate the diagnostic potentials of ICAM-1 in BA versus other forms of NC. METHODS For this purpose, serum ICAM-1 (sICAM-1) and ICAM-1 expression, in liver biopsy using immunohistochemistry, were estimated in 30 patients with BA and compared to that in 20 patients with other forms of NC. sICAM-1 levels were compared to that in 20 healthy controls. RESULTS sICAM-1 levels were significantly higher in BA (1055.9 ± 230.2 ng/mL) than that in cholestasis (604.8 ± 194.8 ng/mL) and the control groups (158.9 ± 78.7 ng/mL) (P < 0.0001). A cut-off value of 793.8 ng/mL had 86.7% sensitivity and 95% specificity in discriminating the BA from the cholestasis group. The biliary expression score of ICAM-1 at a cut-off value of 110 could discriminate between BA and other causes of NC with 100% sensitivity and specificity. Neither serum levels nor liver expression of ICAM-1 scores correlated with disease severity or with fibrosis stage. CONCLUSION These results suggest that ICAM-1 has a diagnostic value in patients with BA and would be a promising helpful tool when investigating patients with NC.

Human endometrial CD98 is essential for blastocyst adhesion. PLoS One 2010; 5:e13380.

Abstract
Background Understanding the molecular basis of embryonic implantation is of great clinical and biological relevance. Little is currently known about the adhesion receptors that determine endometrial receptivity for embryonic implantation in humans. Methods and Principal Findings Using two human endometrial cell lines characterized by low and high receptivity, we identified the membrane receptor CD98 as a novel molecule selectively and significantly associated with the receptive phenotype. In human endometrial samples, CD98 was the only molecule studied whose expression was restricted to the implantation window in human endometrial tissue. CD98 expression was restricted to the apical surface and included in tetraspanin-enriched microdomains of primary endometrial epithelial cells, as demonstrated by the biochemical association between CD98 and tetraspanin CD9. CD98 expression was induced in vitro by treatment of primary endometrial epithelial cells with human chorionic gonadotropin, 17-β-estradiol, LIF or EGF. Endometrial overexpression of CD98 or tetraspanin CD9 greatly enhanced mouse blastocyst adhesion, while their siRNA-mediated depletion reduced the blastocyst adhesion rate. Conclusions These results indicate that CD98, a component of tetraspanin-enriched microdomains, appears to be an important determinant of human endometrial receptivity during the implantation window.

Dempsey A, Roca C, Westhoff C. Vaginal estrogen supplementation during Depo-Provera initiation: a randomized controlled trial. Contraception 2010; 82:250-5. [PMID: 20705153 DOI: 10.1016/j.contraception.2010.04.003] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2010] [Revised: 03/31/2010] [Accepted: 04/02/2010] [Indexed: 11/17/2022]
Abstract
BACKGROUND Irregular bleeding is often cited as the reason for discontinuation of depot-medroxyprogesterone acetate (DMPA) after the first injection. Estrogen supplementation during DMPA initiation may decrease bleeding and improve continuation. STUDY DESIGN This prospective, randomized, controlled trial evaluated estrogen supplementation during DMPA initiation. Women initiating DMPA were randomized to receive an estradiol vaginal ring for 3 months versus DMPA alone. Bleeding diaries and questionnaires at three and 6 months assessed bleeding, continuation and ring acceptability. RESULTS Seventy-one participants enrolled; 49 completed the first follow-up period. The median number of bleeding or spotting days was 16 in the estrogen ring group (n=26) versus 28 in the DMPA alone group (n=23) (p=.19). Seventy-seven percent of the intervention group received a second injection compared with 70% in the DMPA alone group (p=.56). For each additional day of bleeding and/or spotting reported, women were 3% less likely to receive a second injection (OR 0.97, 95% CI 0.94-0.99). Acceptability of the vaginal ring was high among those in the intervention group. CONCLUSIONS Vaginal estrogen supplementation during DMPA initiation is acceptable to women and may decrease total bleeding.
