The ovarian hyperstimulation syndrome in in-vitro fertilization: a Belgian multicentric study. II. Multiple discriminant analysis for risk prediction.

The considerable overlap of distributions of values for different parameters between control and ovarian hyperstimulation syndrome (OHSS) populations makes any single variable inefficient for risk prediction. Combinations of variables were studied in a discriminant function in order to increase predictivity and decrease the false negative rate. Such analyses were performed on two groups of in-vitro fertilization (IVF) patients: all OHSS cases (n = 128) (group A) and only severe OHSS cases (n = 92) (group B).

[Pleurisy in ovarian hyperstimulation syndrome].

The syndrome of ovarian hyperstimulation is an exceptional aetiology of pleural effusion. It should be thought of any young women who are under treatment to induce ovulation. The effusions are exudates and not transudates as occurs in Demons-Meigs syndrome.

We have followed a case of Mixed Connective Tissue Disease (M.C.T.
