Ectopic bone formation in a child with a head injury: complete regression after immobilisation

OBJECTIVE: To study the correlation between microsurgical tubal reversal after tubal sterilization and ectopic pregnancy. METHODS: 1029 women who underwent microsurgical tubal reversal were followed up. The causes of ectopic pregnancy were analysed and discussed. RESULTS: 960 intrauterine pregnanciess and 12 ectopic pregnancies occurred. The 12 ectopic pregnancies were all tubal ones, among which 2 had intrauterine pregnancies. The rate of ectopic pregnancy in the 1029 women was 1.17%, and in the pregnant cases was 1.23%. The ratio of intrauterine pregnancy to ectopic pregnancy was 1:80. The rates of ectopic pregnancy in the 1st, 2nd year and 2 years later after tubal reversal were not significantly different respectively among the tubal reversal and among the pregnant cases. The rates of ectopic pregnancy in the 1st and 2nd 6 months after tubal reversal were not statistically different. The early tubal hydrapertubation could only increase the chance of ectopic pregnancy. The sterilization method, reversal mode, and interval between sterilization and reversal were not related to the ectopic pegnancy. CONCLUSION: When the lesion in the sterilized position is completely removed, the sutures being through the tubal mucosa and the early tubal hydrapertubation not carried out, the chance of ectopic pregnancy can not be increased after tubal reversal. The contraception 6 months after tubal reversal is not related to ectopic pregnancy.     

The risk of ectopic pregnancy after tubal sterilization. U.S. Collaborative Review of Sterilization Working Group

BACKGROUND: Tubal sterilization is an increasingly common method of contraception in the United States. Although pregnancy after sterilization is uncommon, it can occur and may be ectopic. We used data from the U.S. Collaborative Review of Sterilization to estimate the risk of ectopic pregnancy in women who had undergone the common types of tubal sterilization. METHODS: A total of 10,685 women undergoing tubal sterilization were followed in a multicenter, prospective cohort study. We intended to follow all the women for 5 years by means of annual telephone interviews; for women enrolled early in the study, we attempted an additional follow-up telephone interview 8 to 14 years after sterilization. To assess the risk of ectopic pregnancy in these women, we used cumulative life-table probabilities and proportional-hazards analysis. RESULTS: There were 47 ectopic pregnancies in the 10,685 women; the 10-year cumulative probability of ectopic pregnancy for all methods of tubal sterilization combined was 7.3 per 1000 procedures. The cumulative probability varied substantially according to the method of sterilization and the woman's age at the time of sterilization. Women sterilized by bipolar tubal coagulation before the age of 30 years had a probability of ectopic pregnancy that was 27 times as high as that among women of similar age who underwent postpartum partial salpingectomy (31.9 vs. 1.2 ectopic pregnancies per 1000 procedures). The annual rate of ectopic pregnancy for all methods combined in the 4th through 10th years after sterilization was no lower than that in the first 3 years. CONCLUSIONS: A history of tubal sterilization does not rule out the possibility of ectopic pregnancy, even many years after the procedure.     

Blockade of morphine-induced place preference by diazepam in mice

We assessed the efficacy of combined laparoscopic and minilaparotomy for outpatient microsurgical reversal of extensive tubal sterilization in 11 women undergoing the procedure and followed for a mean of 24.7 months. All patients desired reversal of extensive tubal sterilization, and had 4 cm or less of the longer oviduct remaining. The mean operating time was 110 minutes, and the mean total cost was $5067. There were no major complications. Two women were treated for uncomplicated cystitis within 1 month of surgery. Five (45%) of 11 women delivered viable infants; one patient had two ectopic pregnancies. These preliminary data suggest that outpatient combined laparoscopy and minilaparotomy may be effective in patients who desire restoration of fertility after extensive tubal sterilization.     

Tubal pregnancy

139 cases of tubal pregnancy were analyzed from different points of view over a 10-year period. The ratio of tubal abortion to tubal rupture, both as a result of tubal pregnancy, was determined in this sample at 1:1. Between abortion and rupture a clear difference in time lapse was found from the last regular menstruation to the culmination of the specific symptom. The average age of the patients studied was 28 years. 40% were nulliparae, 10% had been operated on for a previous extrauterine pregnancy. From the histories of these patients it was revealed that 14% had previously had adnexitis, although genital tuberculosis is considered to play a subordinate role. 4 cases in which an IUD was present were observed. In 45 cases, the tubal pregnancy was accompanied by appendicitis, although in no cases was the right tube found to be obstructed.     

Systemic methotrexate therapy versus laparoscopic salpingostomy in tubal pregnancy. Part II. Patient preferences for systemic methotrexate

OBJECTIVE: To investigate patient preferences for systemic methotrexate therapy relative to laparoscopic salpingostomy in the treatment of tubal pregnancy. DESIGN: Preference assessment in controlled clinical study. SETTING: Four hospitals and one infertility clinic. PATIENT(S): Forty patients who had been treated for tubal pregnancy and 40 nonpregnant controls. INTERVENTION(S): Preference for methotrexate therapy relative to salpingostomy was established during an interview. Two scenarios were offered for methotrexate therapy: one with and one without preceding diagnostic laparoscopy. Hypothetical tubal patency rates after methotrexate therapy were varied in both scenarios until patients switched in their initial preference. MAIN OUTCOME MEASURE(S): Preference for systemic methotrexate therapy. RESULT(S): Only a few patients switched in their initial preference when the tubal patency rate after systemic methotrexate therapy was varied. Most preferred methotrexate therapy without an increase in the tubal patency rate in a scenario without preceding diagnostic laparoscopy. A small group never opted for methotrexate therapy even when it would guarantee a 100% tubal patency rate. CONCLUSION(S): Systemic methotrexate therapy would be preferred by most patients as part of a completely nonsurgical management strategy. Tubal patency was a decisive factor for treatment preference in a minority of patients only.     

Reversible esophageal motility disorder in a patient with sarcoidosis

Hysterosalpingo-contrast sonography was compared with sonographically controlled selective tubal catheterization (STC) in 26 infertile women who complained of infertility. Both procedures were carried out on a single examination date. A group of 10 patients first underwent hysterosalpingo-contrast sonography followed by STC, while 16 first had STC followed by hysterosalpingo-contrast sonography. The main outcome measure was tubal patency. A total of 52 Fallopian tubes was assessed. Hysterosalpingo-contrast sonography showed 39 tubes (75%) and STC 46 (89%) to be patent, 13 tubes (25%) and six tubes (12%) were diagnosed to be proximally occluded, by means of hysterosalpingo-contrast sonography and STC respectively. Concordant diagnosis with both methods was made in 43 of 52 tubes (83%). When hysterosalpingo-contrast sonography was followed by STC, the concordance rate was 85%. When STC was followed by hysterosalpingo-contrast sonography, the concordance rate was 81%. In one patient the diagnosis of proximal occlusion of one tube as determined by hysterosalpingo-contrast sonography and STC had to be correlated in laparoscopy. In a patient, who after hysterosalpingo-contrast sonography and STC, was suspected to have bilateral proximal occlusion of the tubes, considerable bilateral proximal stenosis and distal occlusion was documented at laparoscopy. In conclusion, sonographically controlled STC may correct a misdiagnosis in cases where hysterosalpingo-contrast sonography leads to the finding of proximal tubal obstruction. The combination of hysterosalpingo-contrast sonography and STC as an out-patient investigation method for tubal patency assessment in infertile women avoids anaesthesia and radiation. For this reason we recommend the combination of sonographically controlled STC with hysterosalpingo-contrast sonography, at least in cases where proximal tubal occlusion is suspected after hysterosalpingo-contrast sonography. The influence of the order in which the two methods are used on the results of both should be investigated in a randomized study.     

Discriminability in length of lines in the Müller-Lyer figure

OBJECTIVE: To compare patients' health-related quality of life after systemic methotrexate therapy versus laparoscopic salpingostomy for tubal pregnancy. DESIGN: Multicenter randomized clinical trial. SETTING: Departments of obstetrics and gynecology of six Dutch hospitals. PATIENT(S): Hemodynamically stable patients with a laparoscopically confirmed unruptured tubal pregnancy without signs of active bleeding, who were randomly assigned to undergo either systemic methotrexate therapy or laparoscopic salpingostomy. INTERVENTION(S): Standard health-related quality of life questionnaires administered before and 2 days, 2 weeks, 4 weeks. and 16 weeks after confirmative laparoscopy. MAIN OUTCOME MEASURE(S): Health-related quality of life. RESULT(S): Health-related quality of life was impaired most severely 2 days after confirmative laparoscopy in both treatment groups and improved during follow-up. Health-related quality of life was impaired more severely after systemic methotrexate therapy than after laparoscopic salpingostomy. Medically treated patients had more limitations in physical functioning, role functioning, and social functioning; had worse health perceptions, less energy, more pain, more physical symptoms, and a worse overall quality of life; and were more depressed than surgically treated patients. CONCLUSION(S): Systemic methotrexate therapy had a more negative impact on patients' health-related quality of life than did laparoscopic salpingostomy. This negative impact on patients' health-related quality of life of systemic methotrexate therapy should be taken into account when deciding on the appropriate therapy for tubal pregnancy.     

Combining B-mode ultrasound with pulsed wave Doppler for the assessment of tubal patency

This study was conducted to determine whether the additional use of pulsed wave Doppler improves the diagnostic capacity in assessing tubal patency by hysterosalpingo contrast sonography (HyCoSy). A total of 210 women with a history of infertility were included in this study. HyCoSy was performed after intrauterine injection of Echovist 200. For the assessment of tubal patency B-mode scanning and pulsed wave Doppler ultrasound were performed in the proximal and distal tubal segments. With the combined sonographic procedure 297 tubes (74%) were rated patent, 35 (8%) incompletely obstructed and 70 (18%) completely obstructed. A total of 252 tubes were additionally examined by laparoscopy for reference purposes. Concordant results for both methods were found in 92% of tubes, nine had been rated false negative and 10 tubes appeared to have been rated false positive. The combined sonographic specificity was found to be 85% with a sensitivity of 95%. Peritubal adhesions detected by laparoscopy were found to be the reason for false positive sonographic results in 60% of cases. In conclusion, the combined B-mode and pulsed wave Doppler examination appears to be a non-invasive and low-cost test for the assessment of tubal patency, which should be performed during diagnostic work-up for infertility.     

Dissociation between the inhibitory and stimulatory effects of opioid peptides on cAMP formation in SK-N-SH neuroblastoma cells

This study compared the effects of human follicular fluid (hFF) from women with endometriosis, tubal factor and male factor on the zona binding capacity of human spermatozoa. Samples of hFF were collected from 30 patients, 10 patients for each of the indications of infertility, at the time of oocyte retrieval in an in-vitro fertilization/embryo transfer programme. The hemizona binding assay (HZA) was used to assess the effect of these hFF on the zona binding potential of human spermatozoa. The mean numbers of spermatozoa bound to the zona pellucida after treating the spermatozoa with hFF from endometriosis, tubal factor and male factor were 90.5 +/- 20.9, 108.9 +/- 22.3 and 101.2 +/- 13.4 respectively. These were significantly lower than their corresponding controls, the spermatozoa of which were incubated with Earle's balanced salt solution (endometriosis 238.7 +/- 34.7; tubal factor 210.8 +/- 41.6; male factor 205.4 +/- 26.3; P <0.002). The hemizona binding index (HZI) was similar between male factor samples (52.0 +/- 6.7) and tubal factor samples (53.8 +/- 4.2). Spermatozoa incubated with hFF from endometriosis patients (36.0 +/- 4.1) had an HZI that was significantly lower than those treated with hFF from tubal factor patients (P <0.01). Probably due to small sample size, the differences in HZI between endometriosis samples and male factor samples did not reach statistical significance (P = 0.076). These data suggest that there was a stronger sperm-zona binding inhibitory effect of hFF from patients with endometriosis than from those without the disease.     

Insulin levels after portal and systemic insulin infusion differ in a dose-dependent fashion

BACKGROUND: Before the advent of the falloposcope, the endosalpinx usually evaded endoscopic evaluation. The healthy condition of the tubal epithelium and the patency of the tube are important for development and transportation of early stage embryos. METHODS: Twenty patients had tubal occlusion diagnosed by hysterosalpingography, including 10 cases of hydrosalpinx, five cases of interstitial occlusion and five cases of fimbrial occlusion. Falloposcopy with a linear everting catheter and laparoscopy were performed simultaneously to evaluate tubal lumens and peritubal conditions. RESULTS: An attempt was made to cannulate 30 fallopian tubes in 20 cases with a falloposcope, using a nonhysteroscopic transvaginal approach through a linear everting catheter. The success rate was 93% (28/30). In 15 cases of hydrosalpinx or fimbrial obstruction, 10 patients (67%) were considered to be suitable for in vitro fertilization because of flattened mucosa in the endosalpinx and endotubal adhesions. Normal mucosa was noted in only four patients (27%), who were advised to have tuboplasty. One patient (6%) had normal mucosa without tubal occlusion. In two of the five cases of interstitial occlusion, dye (methylene blue) could not pass the interstitial portion of the fallopian tube when chromopertubation was performed twice. This tubal obstruction was overcome with the linear everting catheter. One patient had the complication of an ampulla wall perforation. CONCLUSIONS: In patients with fallopian tube disease, falloposcopy is a useful technique for evaluating the endosalpinx and providing information for selecting further treatment. In some cases of interstitial occlusion, it may also have a therapeutic effect.     

Normal development and metabolic activity of preimplantation embryos in vitro from patients with polycystic ovaries

Polycystic ovary syndrome (PCOS) is closely associated with high miscarriage rates and, following in-vitro fertilization (IVF), with decreased fertilization rates, suggesting that oocytes and embryos are of poor quality. In this prospective study, we examined the development, metabolic activity and blastocyst cell number of embryos following IVF from 51 patients with either anovulatory PCOS, ovulatory PCOS or tubal disease. The number of oocytes retrieved and the fertilization rates were similar for patients with PCOS and tubal disease. Following embryo transfer, 46% of the patients with PCOS and 36% of patients with tubal disease became pregnant. A similar proportion of surplus embryos from patients with PCOS and tubal disease developed to the blastocyst stage (38% and 43% respectively). Patients with anovulatory PCOS had embryos with less fragmentation which cleaved faster, cavitated earlier and had more cells at the blastocyst stage than embryos from patients with tubal disease. While the profile of glucose uptake and lactate production was similar for all groups throughout preimplantation development, patients with tubal disease who underwent ovulation induction using the 'titrated' regimen optimized for PCOS patients resulted in embryos with reduced pyruvate uptake, in addition to low blastocyst cell numbers. This study demonstrates that with an optimized ovulation induction regimen, embryos from PCOS patients are of good quality and developmental potential.     

Fertility after conservative and radical surgery for tubal pregnancy

A retrospective cohort study was set up to evaluate the effectiveness of conservative and radical surgery for tubal pregnancy towards subsequent fertility. Consecutive patients undergoing conservative or radical surgery for tubal pregnancy between January 1990 and August 1993 in two university hospitals were included in the study. Outcome measures were spontaneous intrauterine pregnancy (IUP) and repeat ectopic pregnancy (EP). Of the 135 patients analysed, 56 underwent conservative surgery and 79 underwent radical surgery. Patients treated with conservative surgery achieved a higher 3-year cumulative pregnancy rate than those treated radically (P < 0.001, log-rank test). In patients treated conservatively, there was only one spontaneous IUP in the period between 18 months and 3 years after the tubal pregnancy. In contrast, patients treated radically continued to conceive in this period. Multivariate analysis showed a fecundity rate ratio (FRR) of 1.9 [95% confidence interval (CI): 0.91 to 3.8] for IUP after conservative surgery in the first 18 months of follow-up. In patients with a history of bilateral tubal disease the FRR was 3.1 (95% CI: 0.76 to 12), whereas in patients without a history of bilateral tubal disease the FRR was 1.4 (95% CI: 0.13 to 16). The FRR for repeat EP was 2.4 (95% CI: 0.57 to 11). Our data indicate a beneficial effect of conservative surgery towards subsequent fertility that was not, however, statistically significant in the multivariate analysis. In view of these inconclusive data and the importance of this major health problem, randomized studies are required to assess whether conservative surgery really improves the fertility prospects of patients with tubal pregnancy.     

Experience with the trans-uterine tubal coagulation with high frequency current and the thermo method under hysteroscopic control (author''s transl)

With the aid of the carbon dioxide hysteroscope, 152 patients underwent transuterine tubal sterilization. 106 women had high frequency current coagulations of the tubes. At follow-up examinations 62 tubes were occluded and 30 showed a unilateral tubal occlusion. These results did not improve by using the thermo coagulation method since only 10 out of 24 patients showed bilateral tubal occlusion and two unilateral tubal occlusions. Up to 20 months following the transuterine tubal sterilization, 28 of the 152 women became pregnant. Of these, 16 became pregnant in spite of hysterosalpingographic evidence of bilateral tubal occlusion. Two patients required emegency laparotomies because of small bowel injuries. Within the coagulation times and temperature ranges used in this series, the results of trans-uterine tubal sterilization are unsatisfactory. It is possible that other types of hysteroscopic tubal sterilizations which are now being developed will be more successful.     

In vitro fertilization/embryo transfer in unexplained infertility and minimal peritoneal endometriosis

BACKGROUND: To compare the outcome of in vitro fertilization/embryo transfer (IVF-ET) in unexplained infertility and infertility associated with minimal peritoneal endometriosis. METHODS: A retrospective analysis comparing results of stimulation, sperm characteristics, cleavage, implantation and pregnancy rates in patients with unexplained infertility and peritoneal endometriosis associated infertility. Couples with tubal infertility constituted a control group. RESULTS: In the unexplained infertility and endometriosis groups similar response to stimulation, similar sperm characteristics and cleavage rates were observed. Compared with tubal infertility lower sperm motility was seen in the unexplained infertility group. Both non tubal infertility groups had lower cleavage rate than was seen in the control group. No differences in pregnancy rate were observed, but a significantly higher implantation rate was seen in unexplained infertility compared with tubal infertility. CONCLUSIONS: Couples with unexplained infertility and infertility associated with minimal peritoneal endometriosis have similar outcomes in an IVF-ET set up. Significantly lower cleavage rates in these groups compared with tubal infertility indicate gamete defects as possible causes of infertility.     

Injection of 5-fluorouracil in the treatment of tubal pregnancy through salpingo-catheter under hysteroscopy

Seventeen women with unruptured tubal pregnancy were given 5-FU through salpingo-catheter under hysteroscopy. In one case the injection failed because the tube opening could not be found. The success rate of salpingo-catheterization was 94.12% (16/17). The cure rate for the tubal pregnancies was 88.24% (15/17). 12 cases received injection once and 3 cases twice. The dose of 5-FU per injection was 250 mg in 10 ml solution. Serum beta-hCG test became negative in 7 to 14 days after the treatment, and signs and symptoms disappeared. Salpingography were done in 8 cases after 2 to 3 months, and all the diseased tubes were found patient. There was little side effects due to this treatment, which is more effective, convenient and less traumatic than injecting 5-FU to the affected site through laparoscopy or systemic administration. It may turn out to be an effective, simple, safe and acceptable new method for treating early tubal pregnancy.     

Platelet transfusion practice: time for renewed consensus

BACKGROUND: Bilateral tubal pregnancies are rare and are usually confirmed simultaneously during the same operation. We report a case in which the right salpingectomy was performed seven weeks before the left salpingectomy. When the right salpingectomy was done, the left uterine tube appeared entirely normal. CASE: A 38-year-old woman underwent laparoscopic surgery for suspected right tubal pregnancy. A right tubal pregnancy was found to have partially aborted into the peritoneal cavity. The left uterine tube was carefully inspected and appeared normal. Histopathology of the right tube showed products of conception and chorionic tissue. Seven weeks after surgery, the woman presented in hemorrhagic shock necessitating emergency laparotomy and left salpingectomy. Histopathology of the left tube confirmed the presence of chronic tissue. The patient did not have coitus between the two salpingectomies. CONCLUSION: The explanation of the presentation is uncertain. However, this case underscores the importance of careful follow-up of patients after laparoscopic surgery for ectopic pregnancies.     

Combined laparoscopy and minilaparotomy for outpatient reversal of tubal sterilization

This retrospective study determines risks, outcomes, and cost savings in microscopic tubal sterilization reversal done by minilaparotomy. From January 1992 to December 1993, 40 women, as outpatients, had combined laparoscopy and minilaparotomy for tubal anastomosis. The mean operating time was 1.7 hours, mean blood loss was 20 mL, and mean recovery time was 3.2 hours. Thirty-seven patients (93%) were discharged on the same day, two stayed for 23 hours, and one patient required hospitalization for 2 nights. There were no immediate or postoperative complications. Early crude pregnancy rate was 60%, with an 8% ectopic rate. Tubal patency was confirmed in 39 (98%). The average total cost to the patient was $5,200. Microsurgical tubal anastomosis can be done safely and successfully on an outpatient basis, reducing costs and morbidity and accelerating the patient's return to activity.     

Necrotizing fasciitis following postpartum tubal ligation. A case report and review of the literature

Necrotizing fasciitis is a rare, but devastating subcutaneous bacterial infection which occurs following breaks in skin integrity, either natural, post traumatic or post surgical. Although it has been described following many surgical procedures, necrotizing fasciitis has not been previously described following postpartum tubal ligation. Necrotizing fasciitis was diagnosed four days after an uncomplicated postpartum tubal ligation via an infraumbilical incision. Rapid surgical debridement with broad spectrum antibiotic coverage provided successful therapy. Postpartum tubal ligation is one of the most common surgical procedures in obstetrics and gynecology, thus reports of complications resulting from this procedure are quite relevant to clinical practice. We present here the first reported case of necrotizing fasciitis following postpartum tubal ligation through an infraumbilical incision.     

Efficacy and safety of permanent cardiac DDD pacing with contemporaneous double spinal cord stimulation

A case of simultaneous bilateral tubal pregnancy resulting from in-vitro fertilization and embryo transfer is presented. Repeated transvaginal ultrasound examinations confirmed an intrauterine sac but no fetus. A diagnosis of early missed abortion was incorrectly made and a curettage was performed. The pathological examination showed the presence of decidua and Arias-Stella phenomenon but no chorionic villi. Diagnostic laparoscopy and laparotomy performed 40 days after embryo transfer (eighth week of gestation), revealed bilateral tubal pregnancy. Bilateral salpingectomy was performed.
