Meiotic segregation, recombination, and aneuploidy was assessed for sperm from a t(1;10)(p22.1;q22.3) reciprocal translocation carrier, by use of two multicolor FISH methods. The first method utilized three DNA probes (a telomeric and a centromeric probe on chromosome 1 plus a centromeric probe on chromosome 10) to analyze segregation patterns, in sperm, of the chromosomes involved in the translocation. The aggregate frequency of sperm products from alternate and adjacent I segregation was 90.5%, and the total frequency of normal and chromosomally balanced sperm was 48.1%. The frequencies of sperm products from adjacent II segregation and from 3:1 segregation were 4.9% and 3.9%, respectively. Reciprocal sperm products from adjacent I segregation deviated significantly from the expected 1:1 ratio (P < .0001). Our assay allowed us to evaluate recombination events in the interstitial segments at adjacent II segregation. The frequencies of sperm products resulting from interstitial recombination in chromosome 10 were significantly higher than those resulting from interstitial recombination in chromosome 1 (P < .006). No evidence of an interchromosomal effect on aneuploidy was found by use of a second FISH method that simultaneously utilized four chromosome-specific DNA probes to quantify the frequencies of aneuploid sperm for chromosomes X, Y, 18, and 21. However, a significant higher frequency of diploid sperm was detected in the translocation carrier than was detected in chromosomally normal and healthy controls. This study illustrates the advantages of multicolor FISH for assessment of the reproductive risk associated with translocation carriers and for investigation of the mechanisms of meiotic segregation of chromosomes.
Numerous trials have concluded that laparoscopic hysterectomy, compared with total abdominal hysterectomy, causes less postoperative pain and shortens the hospital stay. Many view this approach as being more cost-effective, but a recent large, randomized trial demonstrated more major complications after the laparoscopic procedure. The present study compared the length of time in the hospital, time to convalescence, and long-term patient satisfaction in 47 consecutive women who were to have supravaginal hysterectomy. Twenty-three of them were randomized to undergo abdominal supravaginal hysterectomy (ASH) and 24 laparoscopic supravaginal hysterectomy (LSH). Pre-and postoperative procedures were comparable in the 2 groups, and there were no significant differences in demographic features or physical characteristics.The postoperative hospital stay was comparable after ASH and LSH. Operating times were significantly longer with LSH, but estimated blood loss was greater in the ASH group. No intraoperative complications occurred in either group, and no patient was transfused. Self-rated pain 6 hours postoperatively was less in women having LSH. Follow up at 6 weeks showed that patients having ASH required approximately 10 more disability days than those in the LSH group. There were no differences in the number of days analgesics were required or the time needed to resume normal activities. At 6 months, 87% of women having ASH and 91% of those in the LSH group were satisfied or very satisfied with the overall results. More than 90% of women in both groups would recommend their procedure to others.When using a multimodal intervention program of postoperative care, the choice between ASH or LSH may be less important than is generally believed with regard to postoperative time in the hospital and long-term patient satisfaction. EDITORIAL COMMENT(What is with the idea of supracervical hysterectomy? There may be some patients who think that preservation of the cervix has less risk of interfering with sexual function or producing urinary incontinence. However, several prospective, randomized trials from the United States, Holland, England, and Denmark have shown that these ideas are not true-preservation of the cervix does not help with sexual, bladder, or bowel function.Learman et al reported on a relatively small, prospectively randomized series of 135 women from 4 U.S. academic medical centers who were followed for 2 years after hysterectomy (Obstet Gynecol 2003;102:453). They found no statistically significant difference in rate of complication, length of hospital stay, or clinical outcomes specifically related to symptoms of bladder or bowel dysfunction and pelvic and back pain between the total and supracervical abdominal hysterectomy GYNECOLOGY Volume 61, Number 10 OBSTETRICAL AND GYNECOLOGICAL SURVEY ABSTRACT Endometriosis is among the most important causes of chronic pelvic pain (CPP) in women of reproductive age; it reportedly is present in as many as one third of women having diagnostic laparoscopy for pain.
