Sonographic evaluation of the puerperal uterus: correlation with manual examination.

OBJECTIVES: To document uterine involution after vaginal delivery and cesarean section by abdominal sonography and to compare the efficacy of manual examination and ultrasonography. STUDY DESIGN: Postpartum manual and sonographic assessment of uterine involution was performed in 120 patients following vaginal and cesarean delivery with an attempt to build a database of changes in uterine dimensions. The patients' reports on the intensity of uterine contractions and vaginal bleeding were compared to the results of sonographic imaging. RESULTS: Palpation revealed proper uterine involution in 80 and 25% of patients after vaginal delivery and cesarean section, respectively. It could not be performed in 2.5% after vaginal delivery compared to 50% after cesarean section. Uterine length was found to be significantly greater after cesarean section than after vaginal delivery (p = 0.0001), and the anterior uterine wall was significantly thinner than the posterior wall (p = 0.0001). Uterine length was significantly greater in the presence of blood accumulation in the uterine cavity (20.7 cm), than when the uterus was empty (18.8 cm) (p = 0.001). In correlating between the patient's report of intense bleeding and the sonographic picture of blood in the uterine cavity sonography had a sensitivity of 0.56 and a specificity of 0.83, whereas the patients' reports had a positive predictive value of 0.22. The difference in information provided by the patients versus that provided by sonography was highly significant (p = 0.001, chi(2) test). CONCLUSION: Within 3 days after delivery, patients particularly those having had a cesarean section, should undergo uterine sonographic scanning and manual palpation to evaluate involution and presence of blood in the uterine cavity.

Sonographic diagnosis of pelvic adhesions in patients after ovum pickup.

OBJECTIVE: To evaluate the use of transvaginal sonography for the detection of pelvic adhesions by using clear free fluid in the pouch of Douglas found after ovum pickup. METHODS: A prospective clinical study was performed in an infertility unit of an academic research facility. Sonography was performed in 50 women with infertility 3 days after ovum pickup, and the visceral peritoneum of the uterus, the ovaries, and the fallopian tubes was scanned for possible pelvic adhesions. RESULTS: The serosal surfaces of the uterus, ovaries, and fallopian tubes were successfully observed for the presence of adhesions in 86%, 68%, and 20% of the patients, respectively. Improved visualization was associated with an increased amount of pelvic fluid for the uterus (P = .01) but not for the ovaries and fallopian tubes. The amount of fluid in the pelvis correlated with an increased number of retrieved oocytes (P = .07) and a decreased need for manual manipulation to achieve proper imaging of the uterus (P = .001). CONCLUSION: Transvaginal sonography performed in the presence of fluid in the pelvis may show adhesions mainly attached to the uterus and ovaries. Assessment of possible mechanical factors is important in planning treatment of patients with infertility.

Severe unilateral hydrothorax as the only manifestation of the ovarian hyperstimulation syndrome.

BACKGROUND: Unilateral hydrothorax is rarely the sole manifestation of the ovarian hyperstimulation syndrome (OHSS) and is suggestive of the severity of the disease. CASE: A 35-year-old woman presented with mild dyspnea 2 weeks after ovarian stimulation with hMG and hCG and IVF-ET. Chest X-ray revealed a large pleural effusion on the right side. Three consecutive thoracocenteses were needed to drain a total of 6,800 cm(3) of fluid. Following drainage, the respiratory symptoms disappeared. An uneventful pregnancy is in progress. CONCLUSIONS: Thoracocentesis is safe and efficient for the treatment of hydrothorax and may be repeated as often as necessary. Clinicians should be aware of the possibility of unilateral hydrothorax as the sole symptom of OHSS.

Doppler parameters of uterine and ovarian stromal blood flow in women with polycystic ovary syndrome and normally ovulating women undergoing controlled ovarian stimulation.

OBJECTIVE: To test the hypothesis that the increased ovarian sensitivity to gonadotropins observed in women with polycystic ovary syndrome (PCOS) may be due to changes in ovarian stromal blood flow in these patients. DESIGN: Uterine and ovarian stromal arterial blood flow (with transvaginal color Doppler ultrasound) were measured in ten women with PCOS and 12 normo-ovulatory women (control group), undergoing gonadotropin stimulation before in vitro fertilization. METHODS: A careful ovarian stimulation strategy was adopted for the study group in order to avoid ovarian hyperstimulation syndrome and achieve an ovarian response which was comparable to that of the control group. Resistance and pulsatility indices (RI and PI) of the uterine and ovarian stromal arteries were calculated before the onset of gonadotropin treatment, on cycle day 5 (after commencing treatment), day of human chorionic gonadotropin injection, day of ovum pick-up as well as on the day of embryo transfer, and 7 and 12 days later. RESULTS: No significant differences were found in RI and PI between the study and control groups throughout the treatment cycle. CONCLUSIONS: It seems that polycystic ovaries do not bear an inherent disturbance in blood flow dynamics of the uterine and ovarian arteries, as measured by color Doppler, which would explain the increased sensitivity of polycystic ovaries to stimulation with gonadotropins.

Interleukin 1beta in serum of women with preterm uterine contractions.

Preterm delivery is a major obstetric and public health problem, accounting for 50-70% of all perinatal deaths. An enzyme-linked immunoassay (ELISA) test was used to determine serum interleukin 1b (IL-1b) levels in 32 women with preterm contractions compared with 26 women in term labour and 11 normal preterm pregnant women. Women with preterm contractions (with or without treatment) had significantly lower mean serum levels of IL-1b (23.5 pgr/ml) compared with women in term labour (218 +/- 57 pgr/ml), but similar levels to pregnant women not in labour at the same weeks of gestation.

Clinical evaluation of a new model of a transcutaneous electrical nerve stimulation device for the management of primary dysmenorrhea.

Transcutaneous electrical nerve stimulation (TENS) has been proven effective in pain relief of primary dysmenorrhea (PD). We evaluated the efficacy of a new TENS device (Freelady, Life Care, Tiberias, Israel), designed to correct disadvantages of older models used in previous studies, in 102 nulliparous women with PD, who were treated with various types of pain relief medications. Marked pain relief was reported by 58 patients (56.9%) and moderate relief by 31 (30.4%). These subjective findings were supported by the fact that the same number of patients (58 and 31) either stopped analgesic use altogether during the trial or reduced the quantity of analgesics, respectively. The device examined proved to be efficient and safe in controlling the pain and disability caused by PD.

The initial flare-up induced by gonadotropin releasing hormone agonist may serve as a predictor of ovarian response in the current IVF-ET treatment cycle in normogonadotropic women aged 40-48 years.

OBJECTIVE: Our purpose was to assess the potential role of the baseline hormone profile in combination with the initial pattern of response to gonadotropin releasing hormone (GnRH) analogue in predicting ovarian function and hence reproductive outcome in normogonadotropic patients aged 40 years or older undergoing IVF treatment. PATIENTS AND METHODS: A retrospective analysis of 394 controlled ovarian hyperstimulation (COH) cycles that reached the stage of oocyte retrieval was conducted. The study included 163 normogonadotropic (serum FSH < or = 15 IUIL) patients aged between 40 and 48 years who had regular menstrual cycles. Superovulation was achieved using menotropins in combination with GnRH analog (short protocol, beginning on menstrual day 2). The ovarian response was monitored on the third cycle day, the day following the first GnRH analogue administration. RESULTS: Cycle distribution by patient age was 175 (44.4%), 122 (30.9%), and 97 (24.7%), while the patient distribution was 85 (52.2%), 48 (29.5%), and 30 (18.3%) for age groups 40-41, 42-43, and 44-48 years, respectively. The mean total dose of menotropins needed for optimal COH was 1787 IU (range, 600-6000 IU). This dose increased with age, while the yield of oocytes and embryos declined (P < 0.05; ANOVA). A positive correlation was demonstrated between the E2 level on day 3 (GnRH analogue flare effect) and the outcome of the treatment cycle (number of oocytes and embryos). Using multiple stepwise regression analysis, it was demonstrated that the initial (day 3) serum E2 levels, combined with baseline FSH levels, patients's age and body mass index enabled early prediction of the ovarian response in the current IVF-ET treatment cycle (oocytes = 8.2 - 0.18 x Age + 0.17 x BMI - 0.12 x FSH + 0.0042 x E2). CONCLUSIONS: Multiple-parameter analysis demonstrated that the use of the initial E2 response to GnRH analogue stimulation combined with basic clinical data may assist in the prediction of ovarian function and hence the reproductive outcome in normogonadotropic IVF patients aged 40 years or older. This may serve as a clinical tool for improving patient selection and treatment outcome in IVF-ET.

The effect of surgical castration on lipid metabolism in premenopausal and postmenopausal women.

OBJECTIVE: To investigate the effect of endogenous estrogen on lipid and lipoprotein metabolism in premenopausal and postmenopausal women. DESIGN: Prospective randomized study. SETTING: Department of Obstetrics-Gynecology, Beilinson Medical Center and Tel-Aviv University Medical School, Israel. SUBJECTS: Twenty-seven women, 15 premenopausal and 12 postmenopausal, undergoing surgical castration (total abdominal hysterectomy and bilateral salpingo-oophorectomy). METHOD: Blood samples were drawn before the surgical intervention and after a 6-month interval. MAIN OUTCOME MEASURES: Assays were performed for estradiol, luteinising hormone and follicle-stimulating hormone, and triglycerides, total cholesterol, HDL-cholesterol, LDL-cholesterol and total cholesterol/HDL as well as HDL/LDL ratio. RESULTS: No significant differences were found in both groups, before castration and after 6 months. A modest, but statistically significant, rise in triglycerides was observed in the premenopausal group. CONCLUSIONS: The serum lipid and lipoprotein profile encountered in premenopausal and postmenopausal women were unchanged 6 months after surgical castration. The clinical significance indicates that the effect of endogenous estrogen on lipid metabolism is doubtful and should be further investigated.

Insulin resistance in paraplegics--effect of one bout of acute exercise.

Insulin action was assessed in spinal cord injured (SCI) male individuals (n = 5) and compared to controls (C) (n = 5). Mean (+/-SD) age and body weight were 27.0 +/- 5.1 and 24.5 +/- 1.6 years and 68.6 +/- 3.2 and 76.6 +/- 5.0 kg for SCI and C group, respectively. Subjects performed physical activities 2-3 times/week on a non-competitive basis. Using the euglycemic clamp, metabolic clearance rate of glucose (g-MCR) was measured twice, one week apart; at a basal state and then 1 h after aerobic exercise. Exercise consisted of 60 min arm-crank at 20-25 watt and 60 rpm. During the hyperinsulinemic clamp, insulin concentration was 76 +/- 14 and 67 +/- 9 microU.ml-1, in SCI and in controls, respectively. At baseline, g-MCR was comparable in SCI and C individuals (8.1 +/- 2.4 and 8.0 +/- 2.1 ml.kg-1.min-1, respectively). After exercise, g-MCR remained at 7.9 +/- 2.0 and 8.5 +/- 2.6 ml.kg-1.min-1 in SCI and C, respectively. In spite of muscle atrophy, peripheral sensitivity to insulin was not impaired in paraplegics. No increase in insulin response to the exercise stimulus was seen in any of the groups. It may thus be suggested that the daily level of activity and the physical training performed by paraplegics, are sufficient to eliminate a state of insulin resistance, which often develops in extremely sedentary populations.

Once-daily fluocinonide-bifonazole combination for the treatment of vulvar itching and vulvovaginal candidiasis. Preliminary study.

Vulvovaginitis presents a therapeutic challenge. Treatment of vulvovaginal candidiasis with topical imidazole preparations is well accepted. In our work we tested a new cream combining antifungal Bifonazole with a corticosteroid agent (Fluocinonide). The results suggest that most of the patients with vulvovaginitis can benefit from treatment with this new combination cream.

Augmentation of low ovarian response to superovulation before in vitro fertilization following priming with contraceptive pills.

Poor ovarian response to superovulation treatment is observed in a certain group of patients, the so-called 'low responders'. Despite the evolution of sophisticated controlled ovarian hyperstimulation (COH) regimens prior to the in vitro fertilization (IVF), the ideal stimulation protocol for the low responder has yet to be formulated. The objective of this study was to assess the effect of oral contraceptive pills (OCP), administered before the initiation of superovulation, on ovarian response and IVF treatment results in patients with previous 'low response' to exogenous gonadotropin stimulation. The study group comprised 42 patients who had exhibited poor ovarian response to standard superovulation protocols in at least two previous consecutive treatment attempts. Contraceptive pills were administered for 28-42 days and were immediately followed by menotropin treatment. The study group (n=50 cycles) was compared with the control group consisting of previous cycles (n=88) of the same women. Significant differences were noted in peak estradiol levels (983 +/- 739 vs. 517 +/- 249 pg/ml; P <0.01, paired Student's t test) and number of pre-ovulatory follicles between the study and the control groups. Thirty-three of the cycles (66%) reached the stage of ovum pick-up, compared with 22 (25%) of the previous IVF cycles in these women. The mean number of oocytes retrieved was 6.1 +/- 3.0 and 2.4 +/- 1.3 in the study and control groups, respectively (P <0.01; paired Student's t test). Embryo transfer (ET) was performed in 62% of the treatment cycles and resulted in five clinical pregnancies (16.1% per ET). No pregnancies were recorded in the control group. This study demonstrates the beneficial effect of OCP given prior to IVF treatment, and provides an efficient treatment modality for women who consistently respond poorly to standard COH protocols.

Crush injury in pregnancy: an unusual experience in obstetrics.

BACKGROUND: Crush injury is the result of prolonged pressure to the limbs when individuals are trapped under the debris of earthquakes, bombings, and other disasters. Muscle integrity is compromised, and the local and systemic manifestations, including rhabdomyolysis, hyperkalemia, renal failure, and disseminated intravascular coagulation may be fatal. CASE: A 32-year-old woman, gravida 2, para 1, was trapped under fallen masonry at 6 weeks' gestation for approximately 6 hours. On initial examination, she showed early signs of hypovolemic shock and crush injury, including hyperkalemia. Prompt management with fluid therapy and careful monitoring led to a rapid recovery. Antenatal follow-up was routine and concluded in spontaneous delivery of a healthy infant. CONCLUSION: The unique physiology of the pregnant woman may affect the outcome of crush injury, and it presents a particular challenge to the trauma team. The obstetrician should be aware of its dangers and should be an active participant in the prompt management of pregnant victims of crush injury to ensure a satisfactory outcome for both mother and fetus.
