Spontaneous twin cervico-isthmic pregnancy in a grand multiparous woman

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 5 2010
Meral Cetin
Abstract Cervico-isthmic pregnancy is a rare form of ectopic pregnancy and is defined as the implantation of a fertilized ovum in the cervico-isthmic portion. The cause is unknown; local pathology related to previous cervical or uterine surgery may play a role, given an apparent association with a prior history of curettage or cesarean delivery. Transvaginal ultrasonography and ,-human chorionic gonadotrophin assays are useful for diagnosis. Here we report a case of spontaneous twin cervico-isthmic pregnancy in a grand multiparous patient who was diagnosed early in the first trimester with transvaginal ultrasonography. The pregnancy was terminated successfully with methotrexate. Methotrexate seems to be most successful at early gestational ages. [source]


Effectiveness of microlaparoscopy in the diagnosis of premature ovarian failure

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 2 2006

Abstract Aim: Premature ovarian failure (POF) cases contain a mixture of cases possessing follicles (type A) and those depleted of follicles (type B). Differentiation between the two types is important because the treatment policy and pregnancy prognosis vary greatly. The objective of this study was to examine the usefulness of microlaparoscopy in the differentiation of types A and B. Methods: Among 66 patient with POF diagnosed at our department between May 1996 and April 2004, 47 patients who gave informed consent and underwent microlaparoscopy were studied. The cases were divided into four groups based on the laparoscopic ovarian morphology. These groups were analyzed with respect to patient background, blood hormone levels, antinuclear antibody positive rate, visualization of the ovary on transvaginal ultrasonography, presence or absence of follicles in biopsy specimen, and number of follicles. Result: No significant differences in patient background and serum hormone levels were observed between groups. There was a tendency of increase in antinuclear antibody positive rate, increase in proportion of cases with follicles, and increase in number of follicles as the ovarian morphology approached normal. Transvaginal ultrasonography failed to identify the ovary in all the patients. Conclusion: Microlaparoscopy is useful in the differentiation between type A and B POF, and is further expected to become an indicator of response to treatment. [source]


The quality and size of yolk sac in early pregnancy loss

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 5 2006
Fu-Nan CHO
Abstract Background:, Accurate differentiation between normal pregnancy and pregnancy loss in early gestation remains a clinical challenge. Aims:, To determine whether ultrasound findings of yolk sac size and morphology are valuable in relation to pregnancy loss at six to ten weeks gestation. Methods:, Transvaginal ultrasonography was performed in 111 normal singleton pregnancies, 25 anembryonic gestations, and 18 missed abortions. Mean diameters of gestational sac and yolk sac were measured. The relationship between yolk sacs and gestational sacs in normal pregnancies was depicted. The yolk sacs ultrasound findings in cases of pregnancy loss were recorded. Results:, In normal pregnancies with embryonic heartbeats, a deformed or an absent yolk sac was never detected. Sequential appearance of yolk sac, embryonic heartbeats and amniotic membrane was essential for normal pregnancy. The largest yolk sac in viable pregnancies was 8.1 mm. Findings in anembryonic gestations included an absent yolk sac, an irregular-shaped yolk sac and a relatively large yolk sac (> 95% upper confidence limits, in 11 cases). In cases of missed abortion with prior existing embryonic heartbeats, abnormal findings included a relatively large, a progressively regressing, a relatively small, and a deformed yolk sac (an irregular-shaped yolk sac, an echogenic spot, or a band). Conclusion:, A very large yolk sac may exist in normal pregnancy. When embryonic heartbeats exist, the poor quality and early regression of a yolk sac are more specific than the large size of a yolk sac in predicting pregnancy loss. When an embryo is undetectable, a relatively large yolk sac, even of normal shape, may be an indicator of miscarriage. [source]

Ovarian follicular development stimulated by leuprorelin acetate plus human menopausal gonadotropin in chimpanzees

JOURNAL OF MEDICAL PRIMATOLOGY, Issue 2 2005
Nobuhiko Yoshimoto
Abstract:, We attempted ovarian stimulation using gonadotropins in 14 chimpanzees. Subjects were given a single administration of leuprorelin acetate, followed by repeated administration of human menopausal gonadotropin (hMG) for 16,21 days. During the dosing period, the ovarian follicle diameter and count were measured by transvaginal ultrasonography. The hormone administration induced the development of multiple follicles, and multiple oocytes were subsequently retrieved. However, the follicle count was decreased, suggesting atresia, in some subjects. Statistically, the final follicle diameter was dependent on the dosing duration and the hMG dose in the late stage, while the maximum follicle count during hMG administration was dependent on age and the hMG dose in the early stage. Five subjects showed mild ovarian hyperstimulation syndrome (OHSS)-like symptoms with a high serum estradiol (E2) concentration. These results suggest that leuprorelin acetate plus hMG administration successfully stimulates the development of multiple ovarian follicles for oocyte retrieval and that the serum E2 concentration is predictive of OHSS-like symptoms in chimpanzees.

Sonographic markers of exencephaly below 10 weeks' gestation

PRENATAL DIAGNOSIS, Issue 1 2005
R. A. Machado
Abstract We report two cases of exencephaly diagnosed by transvaginal ultrasonography at 8 weeks 4 days and at 9 weeks 3 days of gestation. Both cases presented an irregular cephalic pole, and, in the case seen at 8 weeks 4 days, brain vesicles were also absent, whereas in the case seen at 9 weeks 3 days, the midline echo was indistinguishable with disorganized choroid plexuses. In both cases, anencephaly was evident at 11 and 12 weeks' gestation and the postmortem confirmed the diagnosis. Copyright © 2005 John Wiley & Sons, Ltd. [source]


,Blood On The Tracks' from corpora lutea to endometriomas,

Objective, To detect a direct transition from a haemorrhagic corpus luteum to an endometriotic cyst by serial transvaginal ultrasonographic scans. Design, Prospective observational study. Setting, An academic tertiary care and referral centre for women with endometriosis. Population, One hundred and nine women younger than 40 years, with regular menstrual cycles, undergoing first-line surgery for endometriomas, and not wanting postoperative oral contraception. Methods, Three-monthly transvaginal ultrasonography during the luteal phase for 2 years after surgery. Main outcome measure, Sonographic identification of progression from a haemorrhagic corpus luteum to a recurrent endometriotic cyst. Results, A haemorrhagic corpus luteum was identified in 13 women. Serial ultrasonographic scans demonstrated transition to an endometriotic cyst in 11 (85%) instances and resorption in two. A unilateral endometriotic cyst without previous detection of a cystic corpus luteum was observed in 14 women. Conclusions, Bleeding from a corpus luteum appears to be a critical event in the development of endometriomas. [source]

Eight women diagnosed by transvaginal ultrasonography with unruptured caesarean scar pregnancy underwent operative laparoscopy as an alternative treatment to laparotomy. The ultrasonographic diagnosis of caesarean scar pregnancy was confirmed in all women at laparoscopy. None of the women required conversion of the procedure to laparotomy. The total operative time ranged from 75 to 120 minutes. The total blood loss was limited, ranging from 50 to 200 ml. All women tolerated the operation well and had uneventful recoveries. Our results show that in the hands of a well-trained operator, laparoscopy appears to be a reasonable alternative for the management of an unruptured caesarean scar pregnancy. [source]

Objective To improve prediction of ovulation in normal cycles. Design Collection of women's characteristics and their menstrual cycles. Monitoring and analysis of time relationships between several indicators of ovulation: transvaginal ultrasonography, cervical mucus, basal body temperature, urinary luteinising hormone, and ratio of urinary oestrogen to progesterone metabolites. Setting Each of eight natural family planning clinics was to study 12 women for at least three cycles. Population One hundred and seven normally fertile and cycling women aged 18 to 45. Methods Daily measurements of urinary luteinising hormone, follicle stimulating hormone, oestrone-3-glucuronide and pregnanediol-3, -glucuronide. Basal body temperature recording and cervical mucus checking. Transvaginal ultrasound examination of the ovaries. Main outcome measures Delays between the expected day of ovulation according to the luteinising hormone peak or to ultrasound evidence and the expected days according to the other indices of ovulation. Results Ultrasonography was able to show evidence of ovulation in 283 out of 326 cycles. The average time lag between luteinising hormone peak and ultrasound evidence was less than one day (+0.46) but premature and late luteinising hormone-expected date of ovulation were observed in nearly 10% and 23% of cycles, respectively. Basal body temperature rise was observed in 98% of cycles. Cervical mucus peak symptom, rapid drop in the ratio of urinary metabolites, and luteinising hormone initial rise were all close to ultrasonographic evidence in more than 72% of cycles. Conclusions For accuracy and practical reasons, the cervical mucus peak symptom, the ratio of urinary metabolites and luteinising hormone initial rise might be better indices of ovulation than the luteinising hormone peak.

Objective To determine the value of combinations of cervical interleukin-6 (IL-6), cervical interleukin-8 (IL-8), the phosphorylated isoform of insulin-like growth-factor binding protein-1 (IGFBP-1), and cervical ultrasonography in the prediction of preterm birth. Design Prospective follow up. Setting Oulu University Hospital maternity clinic from February 1997 to July 1998. Population Women with singleton pregnancies (n= 77), referred from outpatient clinics at 22,32 weeks of gestation with symptoms (uterine contractions) or signs (cervical change) of threatened preterm birth. Symptomless women (n= 78) matched for gestational age, parity and maternal age at recruitment were studied as a reference group. Methods A urine sample for bacterial culture was collected, and cervical swab samples for assays of interleukin-6 and -8 and phoshorylated IGFBP-1 were taken before digital cervical examination. A Pap smear for analysis of bacterial vaginosis and samples for analysis of chlamydia and streptococci were also obtained. Cervical measurements were made by transvaginal ultrasonography. The same sampling and cervical measurement were repeated twice at two-week intervals. The cutoff values of the markers were determined by receiver-operating characteristic curve analysis. Main outcome measure Preterm birth (<37 weeks). Results The preterm birth (<37 weeks) rate for women in the study group was 16% (12/77). The cervical interleukin-6 cutoff value (61 ng/L) at first visit had a sensitivity of 73% and a specificity of 61% in predicting preterm birth, with a positive likelihood ratio (LR+) of 1.9 (95% CI 1.2,3.0). An ultrasonographically measured cervical index value of > 0.36 at recruitment predicted preterm birth in 25% (5/20) of the study group compared with 9% (5/54); LR+ 2.2 (95% CI 1.03,4.7). Cervical phosphorylated IGFBP-1 > 6.4,g/L [LR+ 1.8 (95% CI 0.7,2.9)], interleukin-8 > 3739 ng/L [LR+ 1.4 (95% CI 0.9,2.4)], and ultrasonograpic cervical length < 29.3 mm [LR+ 2.7 (95% CI 0.8,9.7)] increased the risk of preterm birth. According to the logistic regression model, a combination of IL-6, and IL-8 and cervical index increased the specificity to 97%, but the sensitivity fell to 30% in detecting preterm birth. There was a significantly increased incidence of puerperal infections if phosphorylated IGFBP-1 concentrations were elevated (> 21.0 ,g/L), 36% (4/11) compared with 4.6% (3/65), LR+ 6.7 (95% CI 2.7,17), the sensitivity being 67% (4/6) and the specificity 90% (63/70). Elevated phosphorylated IGFBP-1 concentrations (> 21.6,g/L) were also associated with an increased risk of neonatal infections; LR+ 8.0 (95% CI 3.5,18). Conclusions An increase in cervical IL-6 concentration and the ultrasonographically measured cervical index appear to be associated with preterm birth. A combination of these markers with measurement of cervical IL-8 appears to be the best predictor of preterm birth. Neither the sensitivity nor specificity of the tests used in this study are good enough to predict preterm birth for clinical decision making. Cervical phosphorylated IGFBP-1 seems to be a marker of puerperal and neonatal infectious morbidity in cases of threatened preterm delivery, suggesting early tissue degradation at the choriodecidual interface.

T. C. Li Consultant Gynaecologist
Objective To investigate the endocrinological and endometrial factors in women with unexplained recurrent miscarriage Design Prospective, case study Setting Recurrent miscarriage clinic, Jessop Hospital for Women, Sheffield Participants One hundred and forty-four women with unexplained recurrent (, 3) miscarriages Methods A blood sample was obtained in early follicular phase (day 3,5) to measure follicle stimulating hormone, luteinising hormone, prolactin, androgens and thyroid function; daily blood/urine samples were obtained from mid-follicular phase to measure luteinising hormone until the luteinising hormone surge was identified; endometrial biopsy and a further blood sample for progesterone measurement were obtained in the mid-luteal phase. A transvaginal ultrasonography was performed to evaluate ovarian morphology. Results Hypersecretion of luteinising hormone or ultrasonographic features of polycystic ovarian disease was present in 8% and 7.8% of women, respectively. The free androgen index was elevated in 14.6% of subjects. In the mid-luteal phase, low progesterone level was found in 17.4% and delayed endometrial development was noted in 27.1% of women. Although women with recurrent miscarriage women and delayed endometrium had significantly lower progesterone levels than those with normal endometrial development, only 8/24 had mid-luteal progesterone levels below 30 nmol/L. Recurrent miscarriage was not associated with hyperprolactinaemia or abnormal thyroid function test. Conclusions Endocrinological and endometrial abnormalities are present in about a quarter of women with unexplained recurrent miscarriage. [source]
