[Acute angle-closure glaucoma despite previous Nd:YAG laser iridotomy: a report on 13 cases].

Background: Nd:YAG laser iridotomy is routinely used as a procedure for primary acute angle-closure glaucoma (AACG). The clear advantage of Nd:YAG laser iridotomy is to resolve pupillary block without opening the eye. Nevertheless it remains unclear whether Nd:YAG laser iridotomy is equally effective as surgical iridectomy.

Leukaemia inhibitory factor gene mutations in infertile women.

The glycoprotein leukaemia inhibitory factor (LIF) is produced by the endometrium and is involved in the control of implantation. In women with unexplained infertility reduced uterine concentrations of LIF have been reported. Studies with mice lacking a functional LIF gene have shown that the LIF protein is essential for implantation of the embryo.
