Severe combined immunodeficiency (SCID): from the detection of a new mutation to preimplantation genetic diagnosis.

Purpose: To describe the identification of a new mutation responsible for causing human severe combined immunodeficiency syndrome (SCID). In a large consanguineous Israeli Arab family, this served as a diagnostic tool and enabled us to carry out preimplantation genetic diagnosis (PGD). We also demonstrated that PGD for homozygosity alleles is feasible.

Blastocyst culture and transfer: lessons from an unselected, difficult IVF population.

Blastocyst-stage transfer has yielded excellent results in good prognosis IVF patients, but its efficacy in the general IVF population has not been clearly demonstrated. The objective of this study was to compare cleavage-stage and blastocyst-stage transfer in a mixed, general IVF population. In a prospective, quasi-randomized study, 152 patients underwent 164 treatment cycles.

Timing intra-Fallopian transfer procedures.

With the gradual decline in the use of zygote intra-Fallopian transfer (ZIFT), current practice is to offer ZIFT almost exclusively to patients with repeated implantation failure (RIF). For practical reasons, the procedure is sometimes deferred by 1 day and embryo intra-Fallopian transfer (EIFT) is performed. The aim of the present study was to compare the reproductive outcome of ZIFT versus EIFT.

Parenting style impacts on quality of life in children with cerebral palsy.

Objective: To assess the impact of parenting style and disease severity on quality of life (QOL) in children with cerebral palsy (CP).

Study Design: Thirty-nine children with CP, their siblings, and their parents participated in the study. Probands and siblings, ages 6 to 18 years, completed questionnaires on parenting style (accepting, rejecting, controlling, and autonomy allowing) using the Children's Report of Parental Behavior Inventory.

Follicular growth and development under continuous gonadotropin-releasing hormone antagonist administration.

Objective: Ovarian follicle and cyst formation have been recognized as an advance phenomenon associated with GnRH agonist administration. With the use of GnRH antagonists, pituitary suppression is immediate and no flare effect and follicle growth are expected. We describe two patients who developed a dominant follicle and presumably ovulated in response to hCG triggering under continuous sole administration of a GnRH antagonist.

Vaginal delivery following caesarean section-the use of oxytocin and prostaglandins.

Five hundred and twenty women with one previous caesarean section underwent a trial of labour in our department during the past five years. They were divided into three groups-those receiving oxytocin, those receiving prostaglandins, and those unstimulated who had spontaneous labour. The obstetric outcomes were compared.

[Papanicolau smears: reducing the false negative rate by improving the method].

Screening for cervical carcinoma precursors by Papanicolau (Pap) smears diminishes the incidence of cervical cancer in screened populations. The Pap smear test has a considerable rate of false negatives and in order to improve its efficiency and sensitivity several types of technologies were developed, two of which are discussed in this review. One entails measures for collecting cells from the cervix into a liquid medium and preparing single layer smears from these cells.

Conversion of laparoscopy to laparotomy due to adnexal malignancy.

Purpose: The purpose of the present report was to assess the conversion rate from laparoscopy to laparotomy due to adnexal malignancy and to identify factors that might assist in the selection of the appropriate operative approach in patients with suspicious adnexal masses.

Methods: A retrospective review of the medical records of women who underwent laparoscopy due to ultrasonically complex adnexal masses. Ninety-five consecutive patients fulfilling these criteria, were identified.

Congenital cytomegalovirus infection: a long-standing problem still seeking a solution.

Objective: The purpose of this study was to review the accuracy of current tests used for the diagnosis of in utero cytomegalovirus infection and to discuss the potential value of preconceptional and postconceptional screening programs for prevention of congenital infection.

Study Design: A computer-assisted search was performed for relevant English language publications between 1987 and 1994. We identified 119 cases of suspected intrauterine cytomegalovirus infection in which either amniotic fluid or fetal blood had been analyzed antenatally.

Premature delivery of small versus appropriate-for-gestational-age neonates. A comparative study of maternal characteristics.

Prematurity and growth retardation of the fetus are major factors affecting perinatal outcome. The purpose of this study was to compare maternal characteristics of 63 women who delivered a preterm, small-for-gestational-age (SGA) neonate with those of 63 women matched for parity and gestational age who delivered a preterm, appropriate-for-gestational-age (AGA) neonate. All women delivered at the Soroka Medical Center between January 1, 1985, and December 31, 1990.
