Silent uterine rupture in an unscarred uterus.

OBJECTIVE: Uterine rupture is one of the most serious obstetric complications, with an increased risk of maternal and perinatal morbidity, and even mortality. CASE REPORT: A multiparous woman came to our labor room at 41 weeks of gestation for induction of labor due to being post-term and having a nonreactive nonstress test. She had no history of abdominal or gynecologic surgery. Emergent cesarean section was performed due to prolonged decelerations shown on the fetal monitor. A 12 cm uterine laceration was identified after opening the abdominal cavity. Fortunately, her uterus was preserved and her postoperative condition was stable. CONCLUSION: To avoid maternal and fetal morbidity, or even mortality, obstetricians should be aware of the possible existence of uterine rupture in an unscarred uterus.

Optimal quantization by use of an amplitude-weighted probability-density function for diffractive optical elements.

We present a method for determining the optimal quantitized phase levels for phase-only diffractive optical elements by taking into account a modified probability-density function (PDF). This modified PDF was obtained from the PDF of the phase distribution weighted by the incident amplitude distribution. We applied the proposed method to construct a multilevel Fresnel zone plate with a focal length of 8 m and a diameter of 6.2 mm upon which was incident a Gaussian beam with a 1/e width of 1.4 mm. The efficiency of a binary design was improved by 26.4% and the signal-to-noise ratio by was improved by 18.2% compared with those obtained by the uniform quantization method.
