Die Inguinal-Hernienplastik nach Lichtenstein: Eine einfache und komplikationsarme Technik, besonders geeignet für die Tageschirurgie [The Lichtenstein inguinal hernia-plasty: a simple and complication-free technique, especially suited for ambulatory surgery].

A consecutive series of 353 patients who underwent Lichtenstein mesh repair for inguinal hernia from the 1st of July 1994 to the 30th of July 1995 were studied. We analysed our indication, technique, complications, follow-up and outcome. Special consideration was given to the advantages and acceptance of day-case surgery. Our results suggest that the Lichtenstein repair should be considered as a new standard procedure, especially outside of hernia centres.

Luc-Actes: une unité à construire

(Résumé de l'ouvrage) This volume contains the papers presented at the 47th Colloquium Biblicum Lovaniense (Leuven, 1998). The general theme of the meeting was the unity of the Gospel of Luke and the Acts of the Apostles. Main papers on this topic were read by R.L. Brawley, J. Delobel, A. Denaux, J.A. Fitzmeyer, F.W. Horn, J. Kremer, A. Lindemann, O. Mainville, D. Marguerat, F. Neirynck, W. Radl, M. Rese, J. Taylor, C.M. Tuckett, and J. Verheyden. While a large majority of scholars agree that Luke intended his work to cover both the past and the continuing history of Jesus (Gospel and Acts), the essays also illustrate the complexities of this view on the unity of Luke-Acts when it comes to interpret the various aspects of Lukan theology, christology, pneumatology, and ecclesiology, the expansion of the Church in light of its Jewish origins, the genre of Luke-Acts, and the literary and stylistic means Luke used to make his work a unity. In total the volume includes some 40 papers, of which 24 are offered papers: L. Alexander, H. Baarlink, M. Bachmann, D. Bechard, T.L. Brodie, G.P. Carras, A. del Agua, C. Focant, G. Geiger, B.J. Koet, V. Koperski, D.P. Moessner, G. Oegema, J. Pichler, E. Plümacher, A. Puig i Tarrèch, U. Schmid, B. Schwank, N. Taylor, P.J. Tomson, S. Van den Eynde, S. Walton, G. Wasserberg, F. Wilk. This collection is an invaluable contribution to current discussions in Lukan study and to a nuanced understanding of the relationship between Luke's two volumes.

Serum-Mediane von Placentaprotein-Markern: Relevanz der Unterschiede zwischen spontanen und nach-in-vitro-Fertilisation eingetretenen Schwangerschaften für das fetale Trisomie-Screening.

Trisomy-21 (Down syndrome) is the most frequent chromosomal abnorm- ality but only one third of cases would be detected by amniocentesis based on maternal age alone. Serum screening tests in the early second trimester increase the detec- tion rate to 60-65%, and more recently it was found that such screening was also possible in the first trimester by quantifying a diffe- rent panel of markers. The concen- trations of these placental proteins are strongly dependent on gestatio- nal age; thus control medians must be established and precise dating is essential. Serum chorionic gonado- trophin (HCG) levels were recently found to be increased in IVF preg- nancies compared to spontaneous gestations, leading to a falsely ele- vated trisomy screening risk. The aim of this preliminary study was to find out whether, in the first-trime- ster screening, the markers similarly differed between IVF and spontane- ous pregnancies which would call for the establishment of separate normal medians for IVF patients. We compared 24 pregnancies ob- tained after ovarian stimulation and IVF with six women after thawed embryo transfer (unstimulated cycle) and 63 gestation- and maternal-age matched spontaneously pregnant controls. A single serum was ob- tained between 6 and 16 weeks of gestation and various placental protein levels determined by im- munometric assays. Serum levels of pregnancy-associated plasma protein A (PAPP-A), which is the major marker in the first-trimes- ter screening test, were reduced in IVF pregnancies: after 9 weeks of gestation, multiples of median (MoMs) ranged between 0.23 and 3.58 (logarithmic mean 0.743). For the frozen/thawed transfers, this value was 1.08. In the 9-12 week group containing 6 cases of IVF, three thawed transfers and 25 con- trols, PAPP-A was significantly redu- ced in the stimulated compared to the nonstimulated cycles. In the late first and early second trimester the difference was not significant in our small group but the trend persisted. Pregnancies after IVF will thus show an increased incidence of false positive results in fetal trisomy-21 screening, and special medians should be established for these pati- ents.
