Emergence of temperament in the neonate: neonates who cry longer during their first bath still cry longer at their next bathings.

We observed that neonates who cried during bathing on day 2 still cried on days 3 and 4. The correlation coefficient, for example, between day 2 and day 3 was r=0.410, p<0.

Poor pregnancy outcome following assisted reproductive technology among women operated on for bilateral endometriomas.

Purpose: To determine the first line of infertility treatment for managing patients with unilateral or bilateral ovarian endometriomas.

Methods: We evaluated pregnancy outcome in patients who had received ovarian surgery for unilateral (Group U, = 47) or bilateral endometriomas (Group B, = 38) and aspiration with or without alcohol fixation for unilateral (Group u, = 37) or bilateral endometriomas (Group b, = 22). Subsequently, 64 of these women, excluding 29 dropouts, underwent assisted reproductive technology.

Elective cryopreservation of all day 5 blastocysts is more effective than using day 6 blastocysts for improving pregnancy outcome in stimulated cycles.

To evaluate the efficacy of cryopreservation of all blastocysts for future transfers in stimulated cycles. We carried out fresh blastocyst transfer cycles on day 5 ( = 290) or day 6 ( = 119) and thawed blastocyst transfer cycles that were frozen on day 5 ( = 136), day 6 ( = 71) or day 6 electively ( = 21). We retrospectively compared the clinical outcome of fresh blastocyst transfers with thawed blastocyst transfers according to the day of blastocyst transfer or freezing.

Beneficial effect of long zona dissection on frozen-thawed blastocysts at a young age.

To assess the appropriateness of assisted hatching using long zona dissection of human frozen-thawed blastocysts at the time of warming, especially in women over 35 years of age or with repeated implantation failures. Of 177 frozen-thawed blastocyst transfer cycles, 89 control cycles had an intact zona and 88 cycles had assisted hatching using long zona dissection of human thawed blastocyst at the time of warming. These two groups were further subdivided by age to a total of four subgroups: ≤34 years (assisted hatching,  = 39; controls,  = 39) and ≥35 years (assisted hatching,  = 49; controls,  = 50).

Newborn hearing screening in a single private Japanese obstetric hospital.

Background: Hearing loss is one of the most common abnormalities present at birth. The authors examined the frequency of newborn hearing disturbance at a single obstetric hospital to exclude technical varieties or varieties of subjects which are inevitable in multiple institutional cooperative studies.

Methods: The newborns were examined with an automated auditory brainstem response screener, the ALGO 2e, on day 4 post-partum.
