The clinical significance of postpartum transperineal ultrasound of the anal sphincter.

BACKGROUND AND OBJECTIVE: To evaluate the clinical significance of postpartum anal sphincter damage by transperineal ultrasonography (TPUS) performed on the day of delivery. METHODS: Continence questionnaires were handed out and TPUS was performed on 154 consecutive primiparous women 6-24h after vaginal delivery. At 2 and 6 months later, complaints and sphincteric sonographic appearance were reassessed. The puerperal women's clinical status and sonographic findings in the immediate and late postpartum period were evaluated. RESULTS: Thirty-five (23%) women complained of anal incontinence on the first postpartum day and anal sphincter damage was demonstrated by TPUS in 31 (89%) of them. Four women with anorectal complaints had an intact anal sphincter by TPUS. Follow-up questionnaires, 2 months later, revealed 30 symptomatic women: all of them had sonographically recognized tears on the initial TPUS and 27 of them had positive findings on the TPUS performed 2 months after birth. Six months after delivery, 27 women reported symptoms and all of them had sphincteric disruption evidenced on TPUS performed on the day of delivery. All the women with intact sphincter on the initial TPUS were asymptomatic 6 months later. CONCLUSION: TPUS findings on the day of delivery are related to long-term anorectal complaints, supporting a potential role for TPUS as a screening aid for anal sphincter tears.

Prediction of cervical involvement in endometrial cancer by hysteroscopy.

OBJECTIVE: This study evaluated the ability of hysteroscopy to preoperatively predict cervical involvement in endometrial cancer. METHODS: The records of 110 surgically staged consecutive endometrial cancer patients treated at our institution from 1997 to 2003 were retrospectively analyzed. Data on demographics, preoperative staging procedures, surgical pathology reports, and adjuvant treatments were retrieved. RESULTS: Fourteen (12.7%) patients had cervical involvement (stage II) according to the surgical pathology report, of whom nine (8.1%) had stage IIA and five (4.6%) had stage IIB. Clinical evaluation by speculoscopy and palpation had failed to reveal any indication of cervical involvement. Preoperative diagnostic hysteroscopy procedures were included. None of the hysteroscopy procedures revealed any suspicious lesion in the cervical canal. CONCLUSION: Hysteroscopy and clinical examination fail to adequately predict cervical involvement in endometrial carcinoma. Fractional D&C appears to be the best method until a more effective alternative becomes available.

Serum lipid oxidizibility in term premature rupture of the membranes.

OBJECTIVE: In our previous studies we have shown that the process of term labor is associated with oxidative stress, as indicated by increased susceptibility of maternal serum lipids to copper induced peroxidation. In order to continue evaluating the role of oxidative stress in the labor process, we next tested whether term premature rupture of the membranes (PROM) is also associated with increased susceptibility of maternal serum lipids to copper induced peroxidation. DESIGN: A controlled prospective study. SETTING: Tertiary care centre. POPULATION: 31 healthy women with term PROM and 19 healthy pregnant women with intact membranes. The women were matched for maternal and gestational age. METHODS: Venous blood was drawn from the women (up to 6h after rupture of the membranes and prior to labor in the PROM group), and the kinetics of copper-induced oxidation of serum lipids ex vivo were monitored spectroscopically at 37 degrees C by continuous recording of absorbance at 245 nm. RESULTS: The lag phase, reflecting resistance of serum lipids to oxidation, was similar in the PROM group when compared to the control group (43.7+/-3.2 versus 41.9+/-1.6 min, P=0.61). However, the maximal rate of oxidation (V(max)) and the maximal accumulation of absorbing products (OD(max)) were shorter in the PROM group when compared to the control group (5.14+/-0.26 versus 6.29+/-0.4010(-3) OD(245) nm/min, P=0.016; 0.61+/-0.03 versus 0.71+/-0.04 OD(245) nm, P=0.07). CONCLUSION: As opposed to term labor, term PROM is not associated with increased maternal systemic oxidative stress when compared to normal pregnant women. The role for oxidative stress in preterm PROM warrants further studies.

Hydrolytic and nonenzymatic functions of acetylcholinesterase comodulate hemopoietic stress responses.

Glucocorticoid-initiated granulocytosis, excessive proliferation of granulocytes, persists after cortisol levels are lowered, suggesting the involvement of additional stress mediator(s). In this study, we report that the stress-induced acetylcholinesterase variant, AChE-R, and its cleavable, cell-penetrating C-terminal peptide, ARP, facilitate granulocytosis. In postdelivery patients, AChE-R-expressing granulocyte counts increased concomitantly with serum cortisol and AChE activity levels, yet persisted after cortisol had declined. Ex vivo, mononuclear cells of adult peripheral blood responded to synthetic ARP26 by overproduction of hemopoietically active proinflammatory cytokines (e.g., IL-6, IL-10, and TNF-alpha). Physiologically relevant ARP26)levels promoted AChE gene expression and induced the expansion of cultured CD34+ progenitors and granulocyte maturation more effectively than cortisol, suggesting autoregulatory prolongation of ARP effects. In vivo, transgenic mice overexpressing human AChE-R, unlike matched controls, showed enhanced expression of the myelopoietic transcription factor PU.1 and maintained a stable granulocytic state following bacterial LPS exposure. AChE-R accumulation and the consequent inflammatory consequences can thus modulate immune responses to stress stimuli.

Neonatal respiratory morbidity after elective cesarean section.

OBJECTIVE: The objective of this study was to examine the rate of respiratory morbidity in neonates delivered by elective cesarean delivery (ECD) at term, with a definite confirmation of gestational age (GA) by 1st-trimester ultrasound. METHODS: Consecutive women carrying a singleton pregnancy and undergoing ECD at term (>38 1/7 weeks), confirmed by 1st-trimester ultrasound, were included in the study group. Multiple gestations, cesarean section (CS) in labor, CS performed after rupture of membranes and induced deliveries were excluded. The control group included women with a singleton pregnancy at term (>38 1/7 weeks) who delivered spontaneously. This group of women was randomly selected during the study period. RESULTS: The study group included 277 women delivered by ECD. The control group consisted of 311 women. Five newborns in the study group and none in the control group were admitted to the neonatal intensive care unit (NICU) due to respiratory disorders (p < 0.02). Excluding diabetic women did not change the results. On multivariate analysis, no other factors were found to independently influence the risk of respiratory complications. CONCLUSION: In our study, the rate of respiratory morbidity was found to be significantly higher in neonates delivered by ECD compared to those delivered vaginally. The fact that GA was confirmed by 1st-trimester ultrasound makes iatrogenic prematurity an unlikely sole cause for this excess morbidity.

[The male's role in the etiology of preeclampsia].

Preeclampsia is a major cause of morbidity and mortality in mothers, fetuses, and neonates worldwide, with 5%-10% of human births being affected. The cause is still uncertain, and many controversies exist concerning its management. Preeclampsia-eclampsia is due to the failure of extra-villous cytotrophoblast to invade the maternal uterine spiral arteries to a sufficient depth, inducing poor vascular exchanges between the mother and the placenta. This physiological endovascular trophoblast invasion represents a remarkable immunological placental-maternal interaction. Recent data strongly indicate an important role for the male partner in the causation of this common pregnancy disorder. This review aims to discuss the relevant literature and to explain how paternal, relational and sexual factors play an important role in the etiology of preeclampsia.

Hyperoxaluria in women with vulvar vestibulitis syndrome.

OBJECTIVE: To determine whether evaluation and treatment of hyperoxaluria in vulvar vestibulitis syndrome (VVS) is justified. STUDY DESIGN: Forty women (mean age, 24.5 years; range, 18-35) diagnosed with VVS at a sex therapy clinic participated. Diagnosis of VVS relied upon Friedrich's criteria: (1) severe vulvar vestibular pain upon touch or attempted vaginal entry, (2) tenderness to pressure localized within the vulvar vestibule, and (3) physical findings confined to vulvar erythema of various degrees. Oxalate was measured in 24-hour urine samples. Women with hyperoxaluria (urine oxalate >50 mg/24 h) were placed on a low-oxalate diet and oral calcium citrate as single therapy and reevaluated 3 months later. RESULTS: Hyperoxaluria was diagnosed in 7 women (17.5%), of whom 1 demonstrated an objective improvement and could have pain-free vaginal intercourse following treatment, yielding a 2.5% benefit from the evaluation and treatment of hyperoxaluria. CONCLUSION: There is no justification for evaluation and treatment of hyperoxaluria in women with VVS due to its low yield and economic burden.

The validity of oral glucose tolerance test after 36 weeks' gestation.

OBJECTIVE: Secretion of anti-insulin hormones plateaus near term, questioning the validity of OGTT (oral glucose tolerance test) during that period. We aimed at assessing the feasibility of OGTT near term as compared to OGTT at 26-32 weeks. PATIENTS AND METHODS: One thousand four hundred and eighty seven pregnant women were screened by GCT (glucose challenge test), and 282 (19%) of them performed an OGTT at 26th-32nd weeks ("early" OGTT) after meeting the threshold value for GCT. Forty-one women with abnormal and 16 with normal early OGTT underwent a repeated OGTT at 36-40 weeks' gestation ("late" OGTT). Blood glucose levels during GCT and OGTT were compared between women with early and late abnormal OGTT and women who converted from early abnormal to late normal OGTT. RESULTS: Thirty-six out of 41 participants (88%) with early abnormal OGTT had abnormal test near term as well (Group I). Five women with an early abnormal OGTT converted to normal according to a late OGTT (Group II). These women had lower glucose levels on both late and early OGTT as compared with Group I. All 16 women who tested normal on early OGTT had a consistently normal late OGTT. Glucose levels for all 57 women did not significantly differ between early and late OGTT. The sensitivity, specificity, and positive and negative predictive values of late OGTT were 88%, 100%, 100%, and 76%, respectively. CONCLUSION: The positive predictive value of late OGTT performed at 36-40 weeks' gestation is 100%. This test may be used to detect gestational diabetes in women near term.

The contribution of laminaria placement for cervical ripening in second trimester termination of pregnancy induced by intra-amniotic injection of prostaglandin F(2)alpha followed by concentrated oxytocin infusion.

OBJECTIVE: Our purpose was to determine whether intracervical placement of laminaria stalks would improve the effectiveness of inducing termination of pregnancies in the second trimester by intra-amniotic injection of prostaglandin F(2)alpha. STUDY DESIGN: This is a prospective randomized clinical trial conducted at Gynecology Department, Lis Maternity Hospital. Fifty women admitted for indicated second trimester pregnancy termination were randomly assigned to receive either intracervical placement of laminaria (n = 25) or not (n = 25), with concurrent use of intra-amniotic injection of prostaglandin F(2)alpha and concentrated oxytocin. The outcome measures were: time from induction to delivery and the side effects and complications of treatment. RESULTS: There was no significant difference in the mean interval from induction to delivery in the laminaria and no laminaria groups, being 20 +/- 1.3 (8-30) h versus 19 +/- 1.0 (8-26) h, respectively. In addition, this interval was not different in subgroups of primiparas or multiparas. Other outcome measures such as retained placenta (4% in both groups), post-partum hemorrhage (4% in both groups) gastro-intestinal side effects, fever, and use of analgesia were not significantly different between both groups. CONCLUSION: We found no additional value in placing laminaria stalks when using intra-amniotic injection of prostaglandin F(2)alpha followed by concentrated oxytocin infusion for second trimester termination of pregnancy.

Cervical length, multifetal pregnancy reduction, and prediction of preterm birth.

PURPOSE: To evaluate the application of transvaginal sonography assessment of cervical length before fetal reduction for predicting spontaneous preterm birth in triplet gestations reduced to twins. METHODS: This retrospective study was conducted at the ultrasound unit of a university-affiliated municipal hospital. The study cohort consisted of 25 women with triplet gestations following ovulation induction or assisted-reproduction techniques who underwent fetal reduction to twins. Cervical length was assessed via transvaginal sonography before fetal reduction, and data on pregnancy outcome were retrieved from maternal records and/or maternal interviews. RESULTS: Cervical length (mean +/- SD) at reduction was 4.0 +/- 0.85 (range: 1.2-5.5). Five women were excluded from statistical evaluation because pregnancy complications precluded spontaneous delivery. Two of 3 (67%) women with a cervical length of <3.5 cm delivered prior to 33 weeks' gestation compared with 1/17 (6%) women with a cervical length > or = 3.5 cm. This difference was statistically significant (P < 0.05). The sensitivity, specificity, positive predictive value, and negative predictive value of cervical lengths <3.5 cm to predict delivery prior to 33 gestational weeks was 67%, 94%, 67%, and 94%, respectively. CONCLUSIONS: Measurement of cervical length in triplet pregnancies before fetal reduction provides useful predictive information on the risk for preterm delivery.

Preimplantation genetic diagnosis (PGD) for Duchenne muscular dystrophy (DMD) by triplex-nested PCR.

OBJECTIVES: Duchenne muscular dystrophy (DMD) is a lethal X-linked recessive disorder with an incidence of approximately 1 in 3500 males, caused by mutation in the DMD gene. About 2/3 of DMD cases are caused by gross DMD gene deletion mutations. The purpose of this study was to develop a series of single-cell multiplex-nested PCR protocols for preimplantation genetic diagnosis (PGD) of the most prevalent DMD deletions. METHODS: The protocols were developed on single blood leukocytes from normal males and females and patients with known DMD gene deletion. In the first reaction, 2 of 11 different primer sets (exons 4, 8, 12, 13, 17, 46, 47, 49, 50, 52 and intron 52) were used to allow the simultaneous amplification of different DMD loci and the SRY gender marker, in a single triplex-nested polymerase chain reaction (PCR). Aliquots of this reaction were then subjected to nested PCR in which each locus was amplified individually. Following the successful establishment of single-cell triplex-nested PCR in single leukocytes, the technique was employed in five clinical PGD cases. RESULTS: For each DMD locus, more than 50 single leukocytes from healthy controls and more than 100 single leukocytes from affected individuals with known deletions were analyzed. Amplification efficiency for each tested locus was 98-100%. The false-negative rates for each analysis taken separately was <1%. Taken together, however, the results of the triplex-nested PCR analysis had a false-negative rate of 0%. No contamination was detected in all wash-drop blanks tested. We subsequently performed 18 PGD cycles in 5 DMD carriers. A total of 156 embryos were biopsied and successfully analyzed. Of these, 39 affected embryos were detected and 50 unaffected embryos were transferred (mean = 2.9 +/- 1.1 embryos per cycle). These resulted in three biochemical pregnancies and three clinical pregnancies, all of which have culminated in the birth of normal offspring. CONCLUSION: Triplex-nested PCR using 2 of 11 DMD loci and the SRY gender marker allow PGD for >90% of DMD families with known deletions. These protocols are associated with a high amplification efficiency and accuracy.

Tension-free vaginal tape in the elderly: is it a safe procedure?

OBJECTIVES: To analyze the safety and efficacy of tension-free vaginal tape (TVT) surgery in elderly versus younger women with stress urinary incontinence (SUI). METHODS: A total of 157 consecutive elderly women, aged 70 years and older, and 303 younger women (mean age, 74.8 and 57.2 years, respectively) who underwent TVT for urodynamically-confirmed SUI were prospectively enrolled. Concomitant genitourinary prolapse repair was performed in 84% of the elderly and 67% of the younger women. The main outcome measures were perioperative morbidity, postoperative SUI, persistent or de novo urge incontinence, and voiding dysfunction. RESULTS: The incidence of TVT-related morbidity was similar in both groups, except for significantly fewer cases of bladder perforation among elderly women (1.3% versus 4.9%, P <0.05). However, some age-related morbidity was noted among the elderly women: 2 cases of pulmonary embolism, 2 cases of cardiac arrhythmia, 1 case of severe pneumonia, and 1 case of deep vein thrombosis. The outcome analysis was restricted to 123 elderly and 208 younger women with follow-up of at least 12 months (mean, 30 +/- 12 months; range, 12 to 67 months). The incidence of persistent postoperative SUI and persistent urge incontinence was similar in both age groups. However, de novo urge incontinence was significantly more common among elderly women (18% versus 4%, P <0.05). Two elderly and three younger women had postoperative pressure-flow studies suggestive of bladder outlet obstruction. CONCLUSIONS: Tension-free vaginal tape surgery in elderly women is associated with good outcome results; however, the risk of postoperative de novo urge incontinence, as well as age-related morbidity, is increased.

The safety of low molecular weight heparin therapy during labor.

OBJECTIVE: Current recommendations are to discontinue low molecular weight heparin (LMWH) at least 24 hours prior to labor induction or administering epidural anesthesia. We assessed the safety of discontinuing LMWH 12-24 hours before delivery. METHODS: We evaluated the prevalence of hemorrhagic complications during labor, cesarean or epidural catheter placement in 284 women treated with enoxaparin during pregnancy as compared with 16132 untreated women. Treated participants were divided into subgroups by the various intervals between last LMWH dose hemorrhage-prone events (vaginal delivery,epidural, cesarean etc.). The rate of hemorrhagic complications and hemoglobin values were compared between the study and control groups. RESULTS: Postpartum hemorrhage was uncommon and occurred in 2.1% and 1.9% in study and control groups, respectively (p=0.13). Antenatal as well as postnatal hemoglobin values were very similar for treated and untreated women. No differences were noted between women who discontinued enoxaprin 12-24 hours before labor and those who discontinued treatment later with regard to maternal hemorrhagic complications. No spinal hematomas were report among 12792 treated and un-treated women who had epidural or spinal block. No hemorrhagic neonatal complications were encountered. CONCLUSION: Discontinuing LMWH more than 12 hours before delivery is safe in relation to maternal hemorrhagic complications.

Enhanced erythrocyte aggregation in clinically diagnosed pelvic inflammatory disease.

OBJECTIVE: Enhanced erythrocyte aggregation, revealed using a simple bedside test, has been found recently in several inflammatory conditions. The diagnosis of pelvic inflammatory disease (PID) is at times difficult because of the vague symptoms and signs, but is crucial because even mild PID can have future reproductive consequences. Our objective was to determine the degree of erythrocyte aggregation in PID. The demonstration of an increase in aggregation could be of additive value in cases in which the diagnosis is difficult. STUDY DESIGN: A prospective case-control study was conducted. Fifteen consecutive women diagnosed clinically as having PID based on Centers for Disease Control and Prevention criteria, and 15 matched controls were enrolled. Blood samples were drawn for hematologic indices, C-reactive protein, fibrinogen levels, and red cell aggregation. We studied the degree of red cell aggregation using a simple slide test and image analysis. The variable measured was the erythrocyte percent (EP), equivalent to the slide area covered by erythrocytes. RESULTS: Erythrocyte percent was 59.6 +/- 4.2 and 80.0 +/- 3.6 for the study group and controls, respectively (P <0.001). A significant difference was noted also for the other hematologic and biochemical markers of inflammation between patients and the controls. CONCLUSIONS: We conclude that the degree of erythrocyte aggregation is increased in PID. Its simplicity, rapidity, and low cost should be further evaluated as a diagnostic tool in the context of this frequent disease.

Chorioamnionitis associated with Crohn's disease and azathioprine treatment: a case report.

This paper reports a case of S. constellatus chorioamnionitis in a pregnant Crohn's disease patient who was taking azathioprine. Chorioamnionitis is a major cause of perinatal morbidity. Azathioprine, an immunosuppressive antimetabolite, is widely used to treat inflammatory bowel disease. Streptococcus constellatus is a Gram-positive bacterium that has not previously been associated with chorioamnionitis. A high index of suspicion for chorioamnionitis and unusual pathogens should be maintained in the management of obstetric patients on immunosuppressive agents.

Childhood nocturnal enuresis in vulvar vestibulitis syndrome.

OBJECTIVE: To define correlations between vulvar vestibulitis syndrome (VVS) and childhood nocturnal enuresis and the effect of biofeedback therapy. STUDY DESIGN: Of 104 women diagnosed with VVS, 54 (30 with primary vulvar vestibulitis syndrome [PVVS] and 24 with secondary vulvar vestibulitis syndrome [SVVS], mean age 24.5 years) chose Glazer biofeedback therapy. Information on lower urinary tract symptoms was recorded at the initial and final visits. RESULTS: Eight of the 30 women with PVVS (26.6%) had a history of childhood enuresis as compared to none of the women with SVVS (p < 0.01). The 8 women developed lower urinary tract symptoms following biofeedback treatment. None of the women with SVVS had urinary symptoms before or following biofeedback therapy. The high, unstable baseline muscle tone revealed by the Glazer technique to be present in all VVS patients underwent substantial reduction and stabilization at the end of biofeedback therapy. CONCLUSION: Childhood nocturnal enuresis is apparently common among women with PVVS. New urinary symptoms may develop following biofeedback therapy for PVVS.

Perinatal outcome among non-residents in Israel.

BACKGROUND: Foreign workers in Israel are not covered by the comprehensive medical insurance that all Israelis receive. They have national insurance and injury-related coverage, which does not include routine pregnancy follow-up OBJECTIVES: To compare perinatal outcome between partially insured non-resident migrants in Israel and comprehensively insured Israeli women. METHODS: Parameters of perinatal outcome were compared between 16,012 Israeli and 721 foreign women living in Israel. Outcome measures included birth weight, distribution of gestational age at delivery, neonatal complications, cesarean section, neonatal intensive care unit admission, intrauterine fetal death rates, and duration of post-partum hospitalization. RESULTS: Deliveries prior to 28 weeks gestation occurred more frequently among non-residents (1.3% vs. 0.6%, P < 0.001). Gestational diabetes and preeclamptic toxemia were significantly more prevalent among non-residents (3.2% vs. 1.9%, P < 0.05 and 4.9% vs. 3.1%, P < 0.05, respectively). The cesarean rates were 18% and 35% for residents and non-residents, respectively (P < 0.001), and the post-cesarean recovery period was longer among non-residents (4.8 vs. 3.6 days, P < 0.05). The mean birth weight was similar in the two groups (3,214 vs. 3,231 g), although macrosomia (>4,000 g) was more prevalent among non-residents, who also had higher rates of NICU admission ((9.6% vs. 8%, P < 0.05) and intrauterine fetal death (6.6/1,000 vs. 3.7/1,000, P < 0.05). CONCLUSIONS: Non-resident parturients in Israel are more susceptible to an adverse perinatal outcome than their Israeli counterparts. We suggest that government subsidization of non-residents' health expenditures would reduce the differences in perinatal outcome between these two groups.

[Post partum anal incontinence].

Vaginal delivery is one of the main causes of anal incontinence. While previously postpartum anal incontinence was attributed to neurological damage to the pelvic floor and the rectal sphincter, today we know that mechanical injury plays an important role, especially when symptoms start soon after delivery. Risk factors for postpartum fecal incontinence are: forceps delivery, nulliparity, birth weight over 4 kilograms and persistent occiput posterior presentation of the fetal head. Anal incontinence developed in 42% of women who had posterolateral episiotomy. Therefore, the main focus of the treating physician should be on prevention by avoiding birth trauma followed by early recognition and skilful correction.
