A Case of Cornual Pregnancy after Ipsilateral Salpingectomy for Isthmic Pregnancy.

The patient was a 32-year-old woman, gravida three, para one with one prior cesarean section. She became pregnant spontaneously, but the pregnancy implanted in the isthmus of the right fallopian tube, and therefore, she underwent laparoscopic right salpingectomy. Eight months later, another spontaneous pregnancy occurred. the patient experienced abdominal pain and an ultrasound examination revealed a hematoma around the right cornual region. A wedge-shaped incision was made in the cornual pregnancy using monopolar cauterization, and the myometrium was sutured with a single nodule suture. We report a case of spontaneous cornual pregnancy after ipsilateral salpingectomy for an isthmic pregnancy.

Design and fabrication of a diffractive beam splitter for dual-wavelength and concurrent irradiation of process points.

We report on a dual-wavelength diffractive beam splitter designed for use in parallel laser processing. This novel optical element generates two beam arrays of different wavelengths and allows their overlap at the process points on a workpiece. To design the deep surface-relief profile of a splitter using a simulated annealing algorithm, we introduce a heuristic but practical scheme to determine the maximum depth and the number of quantization levels. The designed corrugations were fabricated in a photoresist by maskless grayscale exposure using a high-resolution spatial light modulator. We characterized the photoresist splitter, thereby validating the proposed beam-splitting concept.
