The direct preparation showed 46,XY,dup(lO)(ql 1.2q23.2). CVS long-term culture and fetal tissue revealed a rare additional abnormality: 48,XXXY,dup(lO)(ql 1.2q23.2). This abnormality represented the major cell line (>85 per cent in 691 cells) in an (XY)/XXY/XXXY/(XXXXY) mosaic (all cell lines presumably bearing the dup(1Oq); the presence of XY and XXXXY cell lines is uncertain). To our knowledge, this is the first report of trisomy lOqll-q23 and of prenatally detected 48,XXXY in chorionic villi. The mosaic could have resulted from early post-zygotic non-disjunctions in a 46,XY,dup(1Oq) or 47,XXY,dup(lOq) zygote. The results from DNA studies of four polymorphisms, mapped to Xp and Xq, support this theory. The literature on prenatally detected cases with sex chromosome tetrasomy and pentasomy and those with additional autosomal abnormalities is reviewed. The reported case underlines the problem of false-negative findings when only direct CVS preparations are karyotyped.

The content of the new oath is discussed as are the reasons for revision of the previous version of the oath. This is followed by a short history of the oath. In the second part of the article the oath is compared with the seven competencies of a medical specialist. The new oath contains elements of six of these seven competencies. This demonstrates that the oath is in keeping with the new medical educational demands.

We present the first documented case where two unidirectional arteriovenous anastomoses connecting the donor twin's larger with the recipient's smaller placental part produce late onset of discordant growth and subsequent twin-twin transfusion syndrome. We conclude that the haemodynamic effects of the anastomoses caused the observed discordant fetal development and not the unequally shared placenta.

Study design: Diabetes insipidus (DI) became manifest during two pregnancies in a woman with postpartum hypopituitarism. Results: Water deprivation-vasopressin administration tests demonstrated partial central DI, corrected with vasopressin in week 12, but only with desmopressin in the third trimester, when placental cystylamino peptidase (vasopressinase) contributes to the severity of the DI. Conclusion: If DI occurs during pregnancy it may be the first manifestation of a latent central DI, which is often idiopathic, but rarely the first symptom of a pituitary or hypothalamic abnormality. It may also be part of Sheehan's syndrome.

During the 14th century well-to-do noblemen like Gian Galeazzo Visconti asked artists like Dei Grassi to transform the textbook into a gallery of miniatures. About eight of these have been produced in ateliers in the North of Italy.This article is the first of a series. The relation with the Visconti family is explained and some versions of the pictures if fresh and dry figs are compared.

The most famous is Taqwim al-sihha, or Tacuinum Sanitatis. From the translation into Latin around 1250 several copies have been made. This article is about the history of the book, about the lay-out in taqwim, tables, and the general subject matter: applications of 280 res non-naturales that each person needs for daily healthcare.
