The effect of zona thinning size on implantation and pregnancy rates of ICSI-ET patients with advanced woman age

Objective: To find if the zona thinning size (in length) of the embryos transferred had any effects on the implantation and clinical pregnancy rates. Design: A prospective randomized study Setting: Infertility and Assisted Reproductive Techniques Centres. Material methods: Sixty infertile women (≥38 years old) who underwent ICSI-ET procedures and accepted to join this study were enrolled. Women were assigned as one in 25 µm and the following in 50 µm zona thinning size groups consecutively, according to the order of the transfers. Thirty patients were assigned in each of the groups. Zona thinning procedure without perforating the zona was performed on the embryos before transfers, using a novel zona laser treatment system. Main outcome measures: Implantation and clinical pregnancy rates. Results: Implantation rates were 0.087±SD 0.160 and 0.099±SD 0.156 (p>0.05), and clinical pregnancy rates were 7/30 (23.3%) and 8/30 (26.7%) (p>0.05), in 25 and 50 μm zona thinning size groups, respectively. Conclusion: Increasing the zona thinning length up to twice the commonly used size did not have any significant effects on the implantation and clinical pregnancy rates in women with advanced age who underwent ICSI-ET treatment

Is there any change in the prolactin levels of nurses in the morning after night shift?

Our purpose was to determine if blood samplings in the mornings after night shifts should be avoided for measuring the basal serum prolactin levels in women working at night and with regular menses; 20 nurses with regular menses, all working only at night shifts, were enrolled in this study. Serum prolactin levels of the subjects were determined twice, first in the morning after a typical night's sleep, with no intercourse within the previous 24 hours, second, in the morning after a typical night shift. All measurements of serum prolactin levels were performed in the follicular phase of the menstrual cycle. Prolactin levels in the mornings after typical night's sleeps and in the mornings after typical night shifts were not significantly different. Prolactin level in the morning after a night shift of a woman with regular menses may represent basal prolactin level of that woman

Reproducibility of the Finn chamber® nickel patch test in two different phases of the ovulatory menstrual cycle

Background: Studies on nickel patch test reactivity and reproducibility of positive tests at different points of the menstrual cycle are heterogeneous. Objective: To investigate if non-reproducibilities of positive nickel sulphate patch tests in the two different phases of ovulatory menstrual cycles with the endocrine evidence of luteal phase adequacy are statistically different. Methods: 15 women (group 1) with positive Finn chamber® nickel patch test results in the follicular phase of the ovulatory cycle and 13 women (group 2) with positive Finn chamber nickel patch test results in the luteal phase of the ovulatory cycle were tested again in the counter-phases of their ovulatory cycle, with a scheduled interval of 6 weeks following the first tests. Reproducibilities of the tests in the two groups were evaluated statistically. Results: 3 of the positive test results in group 1 (20%) and 2 of the positive test results in group 2 (15.4%) were nonreproducible. The difference was not statistically significant. Conclusion: The reproducibility of positive Finn chamber nickel patch tests does not seem to be affected by the changes in the follicular and luteal phases of the ovulatory cycle

Laurence-Moon-Biedl syndrome with vaginal atresia

A 15-year-old girl presented with the rare Laurence-Moon-Biedl syndrome, accompanied by vaginal atresia, and cervical dysgenesis. She was treated by hysterectomy and construction of a neovagina with bilateral pudendal thigh flaps. Two brothers and a sister (one of twins) were unaffected but the remaining brother also had the disease
