Where and when should natural killer cells be tested in women with repeated implantation failure?

The aim of this study was to identify the candidates for natural killer (NK) testing and to define the best methodology. For this purpose a prospective study was performed on 73 women with repeated implantation failure (RIF). RIF was considered to exist in patients not achieving clinical pregnancy after three transfers with at least one good-quality embryo.

Renal angiomyolipoma during pregnancy: review of the literature.

The incidence of renal angiomyolipoma (RA) is 0.3% in the general population, and even more infrequent during pregnancy. Pregnancy can increase the risk of rupture, although the causal mechanism is still not clearly defined.

[Sonographic ovarian vascularization and volume in women with polycystic ovary syndrome treated with clomiphene citrate and metformin].

Objective: To measure the vascularization and ovarian volume with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome with stimulated ovulation treatment, and to analyse the differences between the patients treated with clomiphen citrate versus clomiphen citrate and metformin.

Material And Method: Therty patients were studied. Twenty ovulation cycles were obtained with clomiphen citrate and 17 with clomiphen citrate plus merformin (added in case of obesity or hyperglucemy/hyperinsulinemia).

[Reproducibility of the fetal nasal bone measurement by means of bidimensional and three-dimensional ecography during the second trimester of the pregnancy].

Aims: The utility of the valuation-measurement of the nasal bone in the prognosis of chromosomopaties during the second trimester of the pregnancy is demonstrated.

Objective: To evaluate the repeatability of nasal bone measurement during second trimester with bidimensional and three-dimensional sonography.

Material And Method: Nasal bone was measured in 50 single pregnancies.

Pneumomediastinum during the fourth stage of labor.

Postpartum spontaneous pneumomediastinum (Hamman's syndrome) is a very rare event with an estimated incidence of 1 in 100,000 deliveries. It occurs mainly in the second stage of labor and is potentially lethal. We report the case of a 29-year-old primiparous woman during the immediate puerperium (Leff's fourth stage of labor) presenting with acute chest pain, dyspnea and petechiae.

[Urogenital prolapse repair using polypropylene mesh].

Background: Urogenital prolapse is a condition that affects 1 to 43% of post-hysterectomized patients. Since several years some synthetic meshes have been used to repair pelvic floor, and apparently they have advantages over them predecessors.

Objective: To evaluate the efficacy and security of polypropylene meshes in the repair of urogenital prolapse.

Three-dimensional ultrasonography and power Doppler in ovarian cancer screening of asymptomatic peri- and postmenopausal women.

Aim: To determine whether introducing three-dimensional (3D) ultrasonography with power Doppler facilities as a secondary screening test, preceded by annual transvaginal grayscale ultrasonography (TVUS) (followed by transvaginal color Doppler (TVCD) in selected cases) as a primary screening test for ovarian cancer improves the accuracy of ovarian cancer screening studies.

Methods: Annual TVUS was performed on 3,201 peri- and postmenopausal asymptomatic women aged > or =50 years from March 1, 2001 to June 30, 2003. Cystic ovarian lesions in perimenopausal women were routinely reevaluated by TVUS and TVCD at 4-6 week intervals to avoid unnecessary surgical intervention for physiological cysts.
