Immediate Laparoscopic Nontransvesical Repair without Omental Interposition for Vesicovaginal Fistula Developing after Total Abdominal Hysterectomy
Immediate laparoscopic nontransvesical repair for vesicovaginal fistula may be an effective and feasible alternative to traditional repair in select patients
Laparoscopic Surgical Management and Clinical Characteristics of Ovarian Fibromas
Ovarian fibromas may be misdiagnosed as uterine myoma or ovarian malignant tumor. Laparoscopic examination appears to be an effective and safe surgical approach for managing ovarian fibromas
Laparoscopic Myomectomy for Large Myomas
The aim of this study was to assess the feasibility and efficacy of laparoscopic myomectomy (LM) for large myomas. A subpopulation of 51 patients with myomas 8 cm or larger in diameter was selected from 155 patients who underwent LM at Kangbuk Samsung Hospital from July 2003 to November 2006. The mean age of the patients was 34.9±5.6 yr, mean parity was 0.6±0.9, and 8 patients had a previous operative history. The most common operative indication was a palpable abdominal mass (24 patients, 47%). The mean operating time was 85.6±38.9 min, and the mean diameter of the largest myoma was 9.3±1.8 cm. The mean change in hemoglobin concentration was 2.1±1.2 g/dL. Histopathological diagnosis included 49 patients of leiomyoma (96.1%) and 2 patients of leiomyoma with adenomyosis (3.9%). Postoperatively, a transfusion was done in 7 patients, and a case of subcutaneous emphysema was noted. None of the operations was switched to laparotomy. With the newly-developed screw and the port placement system that was modified from the Choi's 4-trocar method to obtain better surgical vision, LM of large myomas proved to be one of the efficient and feasible methods
Increased amounts and stability of telomeric repeat-containing RNA (TERRA) following DNA damage induced by etoposide.
Telomeric repeat-containing RNAs (TERRAs) are long noncoding RNAs transcribed from subtelomeres toward telomeric repeat tracts, which have been implicated in telomere protection and heterochromatin formation. Genotoxic stress leads to upregulation of TERRAs. However, the mechanism of DNA damage-mediated TERRA induction remains elusive. Here, we treated HeLa cells with etoposide, a DNA double-strand break-generating agent, for various times and monitored the levels of TERRAs. Etoposide treatment led to a gradual time-dependent increase in TERRAs. Etoposide-mediated induction was evident in many TERRAs arising from various chromosome loci, including 20q and XpYp. Chromatin immunoprecipitation assays revealed no significant changes in the occupancy of RNA polymerase II at telomeres upon etoposide treatment. Interestingly, TERRAs arising from 20q, XpYp, 10q, and 13q degraded at slower rates in cells treated with etoposide, while degradation rates of TERRAs from many loci tested were nearly identical in both etoposide- and mock-treated cells. Telomere damage occurred from early time points of etoposide treatment, but telomere lengths and abundance of telomeric repeat-binding factor 2 (TRF2) at telomeres remained unchanged. In summary, etoposide treatment led to telomere damage and TERRA accumulation, but telomere lengths and TRF2-mediated telomere integrity were maintained. Etoposide-mediated TERRA accumulation could be attributed partly to RNA stabilization. These findings may provide insight into the post-transcriptional regulation of TERRAs in response to DNA damage
Does Single-Port Laparoscopic Surgery Reduce Postoperative Pain in Women with Benign Gynecologic Disease?
Prenatal detection of de novo inversion of chromosome 9 with duplicated heterochromatic region and postnatal follow-up
Coexisting ovarian and tubal pregnancies on opposite sides after intrauterine insemination: a case report
Abstract Background Ovarian pregnancy is very rare, and contralateral tubal pregnancy coexisting with ovarian pregnancy must be even rarer. Case presentation A 33-year-old Korean nulliparous woman was referred to our hospital because she suffered lower abdominal pain and had missed her periods after controlled ovarian hyperstimulation and intrauterine insemination. We could not identify any normal gestational sac in the endometrium, or specific ectopic pregnancies, on an initial ultrasound scan. However, there was a large hematoma in the cul-de-sac and free fluid in the right paracolic gutter. We decided to perform emergent laparoscopic surgery. We found contralateral tubal and ovarian ectopic pregnancies. Conclusion To the best of our knowledge, this is the first report of a case in which a patient underwent laparoscopic right salpingectomy and left ovarian ectopic mass excision due to contralateral tubal and ovarian ectopic pregnancies after assisted reproductive technology
