Neonatal outcome of preterm discordant twins.

Objective: To estimate the influence of fetal growth restriction (FGR) on neonatal morbidity and mortality among premature discordant twin neonates.

Study Design: Our medical records (2002-2007) of preterm twins born at 24-37 weeks' gestation were reviewed. Significant discordance was defined as >15% difference in birth weight.

Clomiphene citrate vs. letrozole for cryopreserved-thawed embryo transfer: a randomized, controlled trial.

Objective: To assess the endometrial thickness, hormonal status and pregnancy rates with clomiphene citrate (CC) vs. letrozole in frozen-thawed embryo transfer protocols.

Study Design: Nineteen patients who had previously undergone in vitro fertilization (IVF) with embryo cryopreservation were prospectively and randomly enrolled in a randomized, controlled trial.

The complexity of management of pregnancy-associated malignant soft tissue and bone tumors.

Objective: The incidence of musculoskeletal tumors during pregnancy is very low. The aim of this study was to summarize our experience in treating a large cohort of pregnant patients diagnosed with these rare tumors.

Methods: Women diagnosed with musculoskeletal tumors during pregnancy or immediately after delivery were identified retrospectively in our database between 1996 and 2006.

Comparison of efficacy of two techniques for testicular sperm retrieval in nonobstructive azoospermia: multifocal testicular sperm extraction versus multifocal testicular sperm aspiration.

To compare the efficacy of 2 sperm-retrieval procedures, testicular sperm extraction (TESE) and testicular sperm aspiration (TESA), during the same procedure using the same subjects as their own controls. The presence of mature testicular sperm cells and motility were evaluated in 87 men with nonobstructive azoospermia (NOA) by means of multifocal TESE and multifocal TESA, which were performed during the same procedure using the same subjects as their own controls. Sperm cells were recovered by TESE in 54 cases, but by TESA in only 36 cases.

Severe hypospermatogenesis in cases of nonobstructive azoospermia: should we use fresh or frozen testicular spermatozoa?

The aim of this comparative clinical study was to examine whether the fertilizing potential of frozen-thawed testicular sperm in the most severe cases of hypospermatogenesis is reduced compared with fresh testicular sperm. The results could determine the necessity of using fresh testicular sperm cells, which mandates involving the spouse by performing simultaneous in vitro fertilization intracytoplasmic sperm injection (IVF-ICSI) treatment in this subgroup of nonobstructive azoospermia (NOA) patients. We studied 13 couples in which the husband was diagnosed as having NOA and few motile testicular sperm cells or only immotile testicular sperm cells were isolated by testicular sperm extraction (TESE).
