Design: Randomized, comparative study. Setting: Department of obstetrics and gynecology in a primary reference hospital at Puebla City, Mexico. Sample: 396 women requiring CS signed informed consent and were randomly allocated to the post-placental application of LNG-IUS (198) or Copper T 380 A (198). Methods: Follow up visits at 6 weeks, and 6 and 12 months were performed. Main Outcomes Measures: IUDs expulsion, maternal and babies’ health conditions, breastfeeding and menstrual patterns, adverse effects and pregnancies. Differences between groups were analyzed by Fisher and X2 tests, Odds ratios, relative risk and 95% confidence limits, as appropriate. Results: After one year of follow up, no pregnancies were reported. The IUD expulsion rate was 4.5% in each group. LNG-IUS users had a higher incidence of amenorrhea (OR 2.5 95% CI 2.2 - 3) and menstrual patterns significantly brief and lighter than Copper T 380 A (p < 0.001) with lower incidence of dysmenorrhea (OR 0.1 95% CI 0.04 - 0.2). No detrimental effects of LNG-IUS on breastfeeding was observed and interestingly babies weights of LNG-IUS users was slightly above the average for age compared with Copper T 380 A users. This was probably related with a major proportion of women with normal ferritin serum levels (94% vs 68%) leading to better mother’s general condition. Conclusions: LNG-IUS inserted during CS provides high efficacy contraception with additional benefits, mainly reducing menstrual bleeding and doing so, faster recovery of ferrous homeostasis after CS.展开更多

It is an extremely rare type of adenomyosis.CASE SUMMARY Herein, we report an unusual case of a giant cystic mass in the pelvic cavity after uterine myomectomy. The patient complained of abnormal uterine bleeding and severe dysmenorrhea. After a levonorgestrel-containing intrauterine device(LNG-IUD) was inserted, her symptoms were greatly alleviated. However, the LNG-IUD was detected in the cystic cavity during the follow-up. For fear of the intrauterine device migrating into and damaging the surrounding viscera,surgical treatment was proposed. Therefore, laparoscopic resection of the lesion and removal of the LNG-IUD were performed and cystic adenomyosis with an LNG-IUD out of the uterine cavity was diagnosed.CONCLUSION We believe that myomectomy breaking through the endometrial cavity may have been a predisposing factor for the development of cystic adenomyosis in this case.展开更多

Menstrual pattern, pictorial blood loss assessment chart score, adverse effects, and rate of acceptability and satisfaction were recorded at 3, 6 and 12 months after procedure. Results: The mean age of the sample was 39.92?yrs ± 3.27.?Indication for device insertion was DUB in 81.42% (57), fibroid 8.57% (6), adenomyosis in 10% (7). The expulsion rate was 4.2% (3), removal rate was 7.14% (5) and continuation rate is 88.57% (62). 2.28% (3) patients underwent hysterectomy because of continuous bleeding even after 3?-?4 months of insertion. On follow-up at one year out of 62 patients, 33.87% (21) were amenorrhic and 51.61% (32) have?regular period, while 3.07% (2) patients had irregular period.?Conclusion: LNG IUS is a less invasive, effective treatment modality for menorrahgia with reasonable efficacy.展开更多

Design: Open non-comparative study. Setting: Obstetrics and Gynecology Hospital at Monterrey, Mexico. Sample: 29 women aged 18 to 40 years with pelvic pain associated with endometriosis confirmed by laparoscopy. Methods: After laparoscopy but before LNG-IUS insertion (basal visit) and 6 months afterwards, modified Endometriosis Health Profile (EHP-30) was applied. Main outcomes measures: Size of change of questionnaire scores, need of additional analgesic therapy and adverse effects. Statistical Analysis: Differences in the questionnaire scores before and after intervention were analyzed by Student t-test. Results: Final analysis set included 29 women aged 31.7 ± 4.7 years years. The ASRM surgical staging of endometriosis was mild in 19.3 moderate in 13.7 and severe in 76% of the patients. The general perception of quality of life improved from 52 at baseline to 98% at six months (p < 0.001). Adverse events were mild in nature, 19 patients reported no adverse events during the study (65.5%). Two patients (6.9%) required the use of concomitant therapy with non-steroidal analgesics for relief of pain. Conclusion: The application of LNG-IUS in patients with pelvic pain associated with endometriosis improved significatively all aspects related with quality of life as measured with Endometriosis Health Profile (EHP-30). We concluded that LNGIUS may be an effective and convenient therapeutic alternative for the management of pain associated with endometriosis.展开更多

The results showed that the Estradiol (E2) and progesterone (P) levels were significantly decreased 2 ovulatory cycles after iusertion of the devices as compared with those before insertion in 3 monkeys (P>0. 001) ,suggesting an evident ovulation-suppressing effect. In 1 monkey, the E2 and P levels were the same before and after insertion,and expulsion of device was found in the monkey later. The plasma LNG concentration in 3 animals was 493. 69-454. 60 pg/ml and plasma LNG was not detected in 1 monkey. The hormone level returned to normal level after removal of the devices.展开更多
