[Drug-induced acute angle closure glaucoma].

Acute angle closure glaucoma is an ophthalmic emergency that can lead to blindness in some cases. The presenting signs are often suggestive, like ocular pain and blurred vision accompanied by headache, nausea and vomiting. These symptoms must be recognized as soon as possible, and the patient must be addressed, urgently, to an ophthalmologist for treatment.

[Apert syndrome or acrocephalosyndactilia type I].

Apert syndrome, or acrocephalosyndactilia type I, is a rare genetic disorder caused by mutations in the FGFR2 gene and characterized by craniosynostosis, craniofacial dysmorphia and symmetrical syndactyly of the hands and feet. The estimated prevalence of this syndrome is 10 to 15.5 cases per 1,000,000 live births.

Supplementation of transport and freezing media with anti-apoptotic drugs improves ovarian cortex survival.

Background: Ovarian tissue preservation is proposed to patients at risk of premature ovarian failure, but this procedure still needs to be optimized. To limit injury during ovarian tissue cryopreservation, anti-apoptotic drugs were added to the transport and freezing media of ovarian cortex tissue.

Methods: Sheep ovaries were transported, prepared and frozen in solutions containing vehicle or anti-apoptotic drugs (Z-VAD-FMK, a pan-caspase inhibitor, or sphingosine-1-phosphate (S1P), a bioactive lipid).

Influence of mouse strain on ovarian tissue recovery after engraftment with angiogenic factor.

Background: For women facing gonadotoxic treatment, cryopreservation of ovarian tissue with subsequent retransplantation during remission is a promising technique for fertility preservation. However, follicle loss within grafted ovarian tissue can be caused by ischemia and progressive revascularization. Several xenograft models using different immunodeficient rodent lines are suitable for studying ovarian tissue survival and follicular viability after frozen-thawed ovarian cortex transplantation.

Strategies for using the sheep ovarian cortex as a model in reproductive medicine.

Objective: To evaluate and compare the distribution and density of primordial follicles within a whole sheep ovary and to gain insight into how to overcome the impact of natural follicular heterogeneity on the experimental results.

Design: Histological study.

Setting: Academic research center.
