MUC1 is a cell-surface and secretory product of endometrial epithelium. Immunohistochemical studies carried out using two different antibodies to the mucin-type tandem repeat region of MUC1 indicate a cell-surface location in proliferative phase glands, with intracellular deposits accumulating in the early secretory phase. Commencing 3-4 days after the luteinizing hormone (LH) peak and continuing into the late secretory phase, secretory MUC1 appears in gland lumens. Uterine flushings were collected as a function of time after the LH peak and were analysed using a two-site enzyme-linked immunosorbent assay for MUC1. Low but measurable concentrations were observed up to day 7, while on days 7-13 much higher values were obtained. In women suffering from recurrent spontaneous miscarriage, the concentration of MUC1 in flushings was significantly lower than in the controls on day LH + 10. Lower values were observed on days 7 and 13. Reduced epithelial secretory function and a resultant change in uterine fluid composition are features of endometrium from recurrent miscarriage patients.

Laparoscopic surgery has many advantages but it is not without complications. The complexity of the surgery significantly influences the complication rate. Laparoscopic surgeons ought to be aware of the possible complications and how they could be prevented, recognized without delay, and managed safely and efficiently. Important complications include injuries to the vessels, bowel and urinary tract. Incisional hernia ought to be reduced by careful closure of the fascia whenever a trocar > or =10 mm is used at the extraumbilical site. Gas embolism is a rare but potentially life threatening complication. Shoulder pain is a minor complication but is exceedingly common; it is less likely to occur if as much gas as possible is removed at the end of the operation while the patient is still in head down Trendelenburg position. Rare complications include pneumothorax, subcutaneous and pre-peritoneal emphysema, cardiac arrhythmia, nerve injury and venous thrombosis. Laparoscopic surgeons should also understand the principles of electrosurgery and how to avoid complications arising from the use of electrical energy including capacitative coupling, direct coupling and insulation failure.

The concentrations of endometrial proteins PP14 and CA-125 were measured in uterine flushings taken on days LH+10 and LH+12 (10 and 12 days after luteinizing hormone surge) of the menstrual cycle from 15 normal, fertile women and 49 women who suffered recurrent miscarriage. The concentration of PP14 was significantly lower in the flushings from the recurrent miscarriage patients than in those from fertile controls on both day LH+10 (median: 1300, range: 3-10 300 ng/ml versus median: 13 933, range: 2174-40 404 ng/ml; P < 0.01) and LH+12 (median: 1560, range: 820-12 100 ng/ml versus median: 14 047, range 1402-62 108 ng/ml; P < 0.05). Similarly concentrations of CA-125 were significantly lower in flushings from recurrent miscarriage women compared to controls on both day LH + 10 (median: 1555, range: 47-6710 U/ml versus median: 6385.5, range 2884-27 731 U/ml, P < 0.01) and LH+12 (median: 2892, range: 956-9974 U/ml versus median: 7127.5, range: 1591-21 343 U/ml; P < 0.05). In contrast there was no significant difference in the concentration of PP14 in plasma samples taken on the same days as the flushings from recurrent miscarriage patients and fertile controls. The concentrations of PP14 in uterine flushings obtained on day LH + 10 or LH + 12 from recurrent miscarriage women during a pre-pregnancy investigative cycle were significantly lower (P < 0.05) in patients who went on to miscarry (median: 1000, range: 9-2900 ng/ml) than those who went on to have a live birth (median: 1440, range: 4-12 100 ng/ml) during a subsequent pregnancy. In contrast there was no significant difference in uterine CA-125 or plasma PP14 concentrations between these two groups of recurrent miscarriage patients. The results suggest that measurements of uterine PP14 and CA-125 may be useful in the assessment of endometrial development in recurrent miscarriage patients and suggest the importance of PP14 in preparing the endometrium for embryo implantation. In addition pre-pregnancy uterine PP14 measurements may be useful in predicting subsequent pregnancy outcome.

Objective To describe and analyse the factors affecting the pregnancy rate of laparoscopic ovarian Design A retrospective study.Setting A specialist infertility clinic based at a teaching hospital in England.Population One hundred and eighteen women, for whom hospital records and follow up data were available, with polycystic ovarian syndrome who underwent laparoscopic ovarian surgery for anovulatory infertility over a five year period, between January 1991 and December 1995.dnlling for polycystic ovarian syndrome in women with anovulatory infertility.Main outcome measures Ovulation and pregnancy rate. ResultsThe cumulative conception rate 12 months after the treatment was 54% . Women who conceived following the surgery had a shorter duration of infertility, were treated with diathermy (rather than laser), had higher pre-operative lutehising hormone levels, were younger and were more likely to have ultrasonographic evidence of polycystic ovarian disease. Logistic multiple regression analysis showed that the duration of infertility, modality used in treatment (laser or diathermy) and the preoperative levels were the main determinants of the outcome. ConclusionWomen with polycystic ovarian syndrome respond favourably to laparoscopic ovarian drilling. The success rate in women with infertility duration of less than three years, treated with diathermy, in whom the pre-operative level was more than 10 IU/L reached 79%.

In this prospective, randomized, controlled clinical study, 21 women underwent a second-look laparoscopy 2-11 weeks after standardized laparoscopic electrosurgical treatment for polycystic ovarian syndrome (PCOS). Following bilateral ovarian treatment, one ovary was randomly chosen to have Interceed applied to its surface using a specially designed applicator, with the other ovary serving as a control. Peri-adnexal adhesions of significant extent and severity developed in 57% of the women and 38% of the adnexa. The incidence of adhesions on the Interceed-treated side was 43%, while on the control side it was 33%. In addition, the extent and severity of the adhesions appeared to be similar on the Interceed-treated and control side. However, larger numbers would be required to determine statistically the effects of Interceed on de-novo adhesion formation after laparoscopic electrosurgical treatment of PCOS, as described here.
