Tubal patency and fertility outcome after expectant management of ectopic pregnancy

Objective: To study tubal patency and fertility outcome of patients with expectantly managed ectopic pregnancy (EP).

Design: A prospective study.

Setting: Department of Obstetrics and Gynecology, Turku University Central Hospital, Turku, Finland.

Patient(s): Thirty patients who wanted to become pregnant again were treated successfully by expectant management of EP.

Intervention(s): Patients were examined with posttreatment hysterosalpingography, and they filled out a questionnaire about their subsequent pregnancies.

Main Outcome Measure(s): Free passage through open lumen showing tubal patency; number of full-term pregnancies and EPs revealing relative rate of subsequent fertility.

Result(s): A free passage through the diseased tube was seen in 93% of the cases (28 of 30). Two of the 24 patients (8.4%) who wanted to become pregnant had an obstruction in the diseased tube. One (4.2%) of them had a normal opposite tube and later had a normal pregnancy. The other (4.2%) had an obstruction in both tubes and subsequently had a repeat EP. One of the 6 patients had an EP (this patient did not want to become pregnant and did not use contraception). However, her posttreatment hysterosalpingography was normal. In total, the subsequent pregnancy rate was 88% (21 of 24), and the rate of repeat EP was 4.2% (1 of 24).

Conclusion(s): Patients who are treated with expectant management have a good long-term fertility outcome. Spontaneous regression of EP does not lead to increased harm or damage to the tube, i.e., the risk for repeat EP is low.     

Genetics: Genetic analysis prior to selective fetal reduction in multiple pregnancy: technical aspects and clinical outcome

Multiple pregnancies resulting from ovarian stimulation areat a higher risk of carrying at least one fetus affected byMendelian or chromosomal anomalies, the incidence of which isdirectly related to the order of multiples. Genetic analysisbefore fetal reduction was offered to both high-and low-riskpregnant women carrying two or more fetuses after ovulationinduction. Chorionic villus sampling (CVS) and fetal reductionwere achieved by transabdominal needling. The use of short-termculture, the polymerase chain reaction and fresh tissue enzymaticanalyses have made it possible for genetic diagnosis to be availablein a few days. A total of 100 patients had multifetal pregnancyreduction performed by a single operator; all of them completedpregnancy and none was lost at follow-up. The total fetal lossbefore 24 weeks was 7% and no statistically significant relationshipwas found with the final number of fetuses and CVS. Perinatallosses (3.9%) were only present in the series with a final numberof two fetuses. Pregnancy duration and birthweight were significantlyhigher in singletons than in twins, but were not related toCVS. The rate of chromosomal disorders was higher (7.2%) inthe study series than in singleton pregnancies not undergoingfetal reduction. Diagnostic error due to incorrect samplingwas reported in 1.5% of cases. These data support fetal reductionas a valuable strategy to improve the outcome of multiple pregnancy.The outcome of pregnancies reduced to singletons was significantlybetter than of those reduced to twins, and was not related toCVS. Therefore, prenatal genetic diagnosis should become anintegral part of counselling on multiple pregnancy, and is stronglyrecommended when reduction to singleton pregnancy is requested.     

腹腔镜在异位妊娠中的诊断和治疗价值

本文分析1982～1987年间收治的544例异位妊娠,其中270例行腹腔镜检查、274例未作腹腔镜检查。两组资料相比提示:腹腔镜检查组诊断符合率高达97.40％;由于能及早明确诊断,故该组腹腔内出血量比未作腹腔镜检查组少,平均为241m1/372ml(P<0.05),需输血例数明显减少30例(11.11％)/134例(48.90％)(P<0.01),输卵管未破裂者增高222例(82.22％)/194例(70.80％)(P<0.01)。270例无术后并发症发生。上述给年轻不孕患者作非手术治疗或输卵管保守手术以保留生育功能提供良好条件。     

82例双胎妊娠及其围产儿分析

自１９８８年１月～１９９３年１２月我院共分娩１０１２４例，双胎８２例。结果表明：双胎组早产，妊高征、贫血、胎膜早破、产后出血和围产儿死亡率明显高于单胎组，为此提出：①有双胎家族史、由药物诱导排卵的孕妇、孕吐严重、先兆流产和子宫大于停经月份者应作Ｂ超检查，有助于双胎的早期诊断。②妊娠３２周以后，双胎孕妇应连续卧床休息，注意营养，治疗合并症，对减少早产、增加新生儿体重和降低围产儿死亡率有重要意义。     

用免疫组织化学方法鉴别异位妊娠与正常妊娠

对57例内膜刮出组织和宫内流出组织均未检出绒毛膜绒毛。用抗血清标记绒毛滋养层的人绒毛膜促性腺激素(HCG)、人胎盘催乳素(HPL)和妊娠特异糖蛋白(SPI),结果18例被标记,37例未被标记。临床证明未被标记的37例为异位妊娠。表明用激素标记子宫内膜可提高异位妊娠的诊断率。     

妊娠妇女凝血-抗凝与纤溶测定的临床意义

目的：检测妊娠妇女和妊高征患者凝血与纤溶的变化，探讨孕妇在不同状态下各项指标的临床意义。方法：将63例妊娠妇女分为正常孕妇组43例和妊高征20例，采用磁珠凝固法检测凝血酶原时间(PT)、部分活化凝血酶时间(APTT)、凝血酶时间(TT)、纤维蛋白原(Fbg)和游离蛋白S(FPS)；免疫比浊法检测D-二聚体(D-D)、血管性血友病因子(vWF)，并与非孕妇的健康对照组作比较。结果：43例孕妇和20例妊高征患者血浆PT、APTT均显示不同程度的缩短；TT延长率在妊娠组仅为1％，而妊高征为18％；两组Fbg水平增高明显；妊娠组FPS与对照组比较差异无显著性，但妊高征患者表现明显降低；两组D-D水平均增高，且妊高征患者明显增高；妊娠组vWF水平与对照组比较尽管差异无显著性，但仍有3例高于对照组；妊高征患者增高率达100％。结论：妊娠妇女与妊高征患者均存在不同水平的凝血活化、纤溶亢进和内皮细胞一定程度的损伤，妊娠期作凝血-抗凝、纤溶指标的检测，对预防出血，降低DIC等的发生率具有指导意义。

Women's knowledge, practises, and intentions regarding correct pelvic floor exercises.

AIM: Although research has demonstrated the efficacy of pelvic floor exercises (PFXs) for the prevention and treatment of female urinary incontinence (FUI), adherence to PFX regimens is commonly poor. There is some evidence that this finding is in part due to a lack of knowledge about how to perform PFXs correctly and misconceptions about the required frequency and duration of PFX regimens. METHODS: By using a sample of 720 postpartum women, this study investigates women's PFX regimens both before and during pregnancy and postpartum. RESULTS: Findings demonstrated that most women were aware of the required frequency for PFXs (at least every second day): just over half had done them this often during pregnancy and 91% intended to do so postpartum. However, few had done them at this level before pregnancy and less than half knew that PFXs should be carried out indefinitely throughout the lifetime. Moreover, only two thirds were confident that they were doing PFXs correctly. CONCLUSION: The findings suggest that, despite good knowledge of the required frequency of PFXs, few women practise them regularly over their lifetime, many apparently perceiving PFXs as relevant only to the childbirth years. Implications for health professionals in addressing these gaps in women's knowledge and practises are discussed.     

囊胚期冷冻胚胎移植的临床应用探讨

目的探讨囊胚期冷冻胚胎移植的临床应用价值.方法对2002年10月～2003年12月在湘雅医院生殖医学中心接受囊胚培养并行囊胚期冷冻胚胎移植的病例进行分析,了解囊胚期与卵裂期冷冻胚胎解冻后的胚胎成活率、植入率及妊娠率.结果冷冻囊胚解冻后胚胎数、胚胎成活率、植入率和妊娠率与卵裂期冷冻胚胎无显著差别(P＞0.05),囊胚解冻后经15 h过夜培养,42枚中有22枚成活,其中8枚Ⅰ,Ⅱ级继续发育或囊胚腔扩张,3例获得妊娠,妊娠率为37.5%.结论囊胚期冷冻胚胎移植同样能达到卵裂期冷冻胚胎移植的临床效果,同时增加解冻与移植间隔时间可更好地选择冻融囊胚移植,对提高妊娠率可能有一定意义.
