RESUMEN

PURPOSE: To assess the effectiveness of a long-acting anesthetic injection into the obturator membrane for pain relief in women undergoing trans-obturator tension-free vaginal tape. METHODS: A total of 22 women were randomized for the intra-operative injection of bupivacaine into one of their obturator membranes: the left or right side. All the participants were asked to define their groin pain on a visual analog scale (scored 0-10 cm) at 1, 6, 12, and 24 h post-operative. For each woman, pain scores were compared between the local anesthetic-injected side and the opposite side. RESULTS: Statistically significant differences were not observed in groin pain scores between the bupivacaine injection side and the no injection side at 1 h (p = 0.76), 6 h (p = 1), 12 h (p = 0.95), and 24 h (p = 0.82) post-operative. CONCLUSION: In women who undergo trans-obturator tension-free vaginal tape procedures, intra-operative intra-obturator injection of local anesthetics is not effective in alleviating the characteristic post-operative groin pain. TRIAL REGISTRATION: This study is registered on ClinicalTrials.gov (NCT03479996).

RESUMEN

Fetal inguinal hernia (FIH) is a rare event and only few cases were published in the medical literature. In the present study, we aimed to characterize the sonographic features, clinical presentation, management, outcomes, and differential diagnoses of FIH. Accordingly, we reviewed all 17 cases of FIH published in the medical literature, including one new case evaluated by our group. All 17 cases (100%) were male, and FIH is presented as a scrotal mass with a mean diameter of 38 ± 9.5 mm. The right side was dominant (62%). Peristalsis was reported in 80% of the cases, and blood flow was reported in two-thirds. Most cases were diagnosed in the third trimester (88%) at a mean gestational age (GA) of 33.1 ± 5.2 weeks. 60% of the cases had isolated FIH, and 40% had another sonographic or genetic abnormality. Three cases (18%) were syndromic with multiple malformations: trisomy 18, skeletal anomalies due to Jarcho-Levin syndrome, and undefined multiple joint contractures. Two cases (12%) had copathologies in the gastrointestinal tract: one had an echogenic bowel due to homozygosity for cystic fibrosis, and the other had low anorectal malformation. Bowel loop dilatation was observed prenatally in both cases and in another one isolated case (18%). GA at delivery was 38 ± 1.8 weeks, and the median time between diagnosis and delivery was 3 weeks. All three cases of neonatal death occurred in syndromic fetuses. All patients with nonsyndromic inguinal hernias underwent definitive surgical repair at a median of 13 days postpartum. No signs of strangulation and only one case of edematous bowel without necrosis have been reported. In conclusion, FIH should be suspected in male fetuses when an intrascrotal mass with peristalsis is diagnosed during the third trimester. Close follow-up until term in the absence of signs of bowel obstruction is reasonable, and in isolated FIH, the prognosis is favorable.

RESUMEN

BACKGROUND: Although most biological systems, including human tissues, contain rubidium, its biogeochemical functions and possible role in neonatal birthweight are largely unknown. An animal study indicated a correlation between rubidium deficiency in the maternal diet and lower newborn birthweight. OBJECTIVE: This pilot study measured rubidium concentrations in amniotic fluid during the second trimester of (low-risk) pregnancy and investigated potential correlations between rubidium levels and third-trimester newborn birthweight-small for gestational age, appropriate for gestational age, and large for gestational age-and between preterm birth and term birth in uncomplicated pregnancies. STUDY DESIGN: This prospective, single-center study investigated a possible relationship between rubidium concentration in second-trimester amniotic fluid and third-trimester birthweight percentile. Amniotic fluid (at a median gestational age of 19 weeks) was sampled to determine rubidium concentration. Maternal and newborn characteristics were obtained from participant and delivery records. RESULTS: After screening 173 pregnant women, 99 amniotic fluid samples were evaluated. Midpregnancy median rubidium concentrations were significantly lower among newborns that were classified as small for gestational age than among newborns that were classified as appropriate for gestational age (106 vs 136 µg/L; P<.01). Based on a logistic regression random forest model, amniotic fluid rubidium was identified as a significant contributing factor to appropriate-for-gestational-age birthweight with 54% of the total contribution. CONCLUSION: Amniotic fluid rubidium concentration seems to be a strong predictor of appropriate-for-gestational-age birthweight and a potential marker for newborn birthweight classifications. In particular, low rubidium concentrations in amniotic fluid during midpregnancy are linked to third-trimester lower birthweight percentile. These findings could potentially serve as a valuable tool for early identification of pregnancy outcomes. Further investigation is necessary to fully explore the effect of rubidium on fetal development.

RESUMEN

It is unclear how maternal glycemic status and maternal iodine status influence birth weight among individuals with mild-to-moderate iodine deficiency (ID). We studied the association between birth weight and both maternal glucose levels and iodine intake among pregnant women with mild-to-moderate ID. Glucose values were assessed using a glucose challenge test (GCT) and non-fasting glucose levels that were determined before delivery; individuals' iodine statuses were assessed using an iodine food frequency questionnaire; and serum thyroglobulin (Tg) and urinary iodine concentrations (UIC) were used to assess each group's iodine status. Thyroid antibodies and free thyroxine (FT4) levels were measured. Obstetric and anthropometric data were also collected. Large-for-gestational age (LGA) status was predicted using a Cox proportional hazards model with multiple confounders. Tg > 13 g/L was independently associated with LGA (adjusted hazard ratio = 3.4, 95% CI: 1.4-10.2, p = 0.001). Estimated iodine intake correlated with FT4 among participants who reported consuming iodine-containing supplements (ICS) after adjusting for confounders (ß = 0.4, 95% CI: 0.0002-0.0008, p = 0.001). Newborn weight percentiles were inversely correlated with maternal FT4 values (ß = -0.2 95% CI:-0.08--56.49, p = 0.049). We conclude that in mild-to-moderate ID regions, insufficient maternal iodine status may increase LGA risk. Iodine status and ICS intake may modify the effect that maternal dysglycemia has on offspring weight.

RESUMEN

Severe iodine deficiency during pregnancy has substantial hormonal consequences, such as fetal brain damage. Data on the potential effects of mild-to-moderate iodine deficiency on the thyroid function of pregnant women and their newborns are scarce and divergent. We investigated the association between iodine intake in pregnancy and maternal and neonatal thyroid function in a region with mild-to-moderate iodine deficiency. Pregnant women's iodine status was evaluated using an iodine food frequency questionnaire, serum thyroglobulin (Tg), and urinary iodine concentration (UIC). Neonatal thyrotropin (nTSH) values were measured after birth. Obstetrics and anthropometric data were also collected. Among the 178 women (median age 31 years) included in the study, median (interquartile range) estimated dietary iodine intake, Tg and UIC were 179 (94−268) µg/day, 18 (11−33) µg/L, and 60 (41−95) µg/L, respectively. There was a significant inverse association of iodine intake with Tg values among the study population (ß = −0.2, F = 7.5, p < 0.01). Women with high free triiodothyronine (FT3) values were more likely to exhibit an estimated iodine intake below the estimated average requirement (160 µg/day, odds ratio [OR] = 2.6; 95% confidence interval [CI], 1.1−6.4; p = 0.04) and less likely to consume iodine-containing supplements (OR = 0.3, 95% CI, 0.1−0.8; p = 0.01). It is possible that thyroid function may be affected by iodine insufficiency during pregnancy in regions with mild-to-moderate iodine deficiency. The relatively small sample size of the studied population warrants further investigation.

RESUMEN

OBJECTIVES: Childhood obesity and iodine deficiency are global public health concerns. Whether maternal iodine status mediates overweight in infancy has yet to be explored. We aimed to assess the relationship between maternal iodine status and infant birth weight, including small and large for gestational age (SGA and LGA, respectively). METHODS: A prospective study was carried out among 134 mother-infant pairs from Israel. Maternal iodine intake and status were estimated via questionnaire and serum thyroglobulin (Tg), respectively. Estimated iodine intake below the Recommended Daily Allowance for iodine sufficiency in pregnancy (220 µg/d) considered Inadequate. Maternal and neonatal thyroid function and anthropometric measurements, as well as maternal thyroid antibodies were also tested. RESULTS: After screening, 118 participants met the inclusion criteria (distributed trimesters I, II and III: n = 3, n = 21, and n = 94, respectively). There was a negative association of iodine intake with Tg values among the study population. Maternal median Tg value was higher than the sufficiency cutoff (16.5 vs 13 µg/L), indicating insufficient iodine status. No SGA cases were found. Inadequate iodine intake was associated with maternal isolated hypothyroxinemia (OR = 3.4; 95% CI 1.2, 9.9) and higher birthweight (including macrosomia and LGA) rates. A suggestive association of elevated Tg with a greater risk of LGA was observed. Offsprings' birth weight percentiles were associated with Tg values in pregnant women with suggestive sufficient iodine status (n = 62, R2 = 0.11, p < 0.05). CONCLUSIONS: Iodine status during pregnancy can be associated with newborn anthropometric index. Maternal inadequate iodine intake may alter fetal growth and might increase the risk of LGA among newborns. These initial findings support the need to further study the impact of iodine deficiency on newborns overweight in Israel and elsewhere.

RESUMEN

INTRODUCTION: Cephalopelvic disproportion (CPD) is one of the most common obstetric complications. Since CPD is the disproportion between the fetal head and maternal bony pelvis, evaluation of the head circumference (HC) relative to the maternal bony pelvis may be a useful adjunct to pre-labor CPD evaluation. The aim of the present study was a proof-of-concept evaluation of the ratio between HC and pelvic circumference (PC) as a predictor of CPD. METHODS: Of 11,822 deliveries, 104 cases that underwent an abdominopelvic CT for any medical indication and who underwent normal vaginal deliveries (NVDs) (n = 84) or cesarean deliveries (CD) due to CPD (n = 20) were included retrospectively. Maternal pelvis dimensions were reconstructed and neonatal HC, as a proxy for fetal HC, was measured. The correlation between cases of CPD and cephalopelvic circumference index (CPCI), which represents the ratio between the HC and PC in percentage (HC/PC × 100), was evaluated. RESULTS: The mid-pelvis CPCI (MP-CPCI) was larger in CD groups as compared to the NVD group: 103 ± 11 versus 97 ± 8%, respectively (p = 0.0003). In logistic regression analysis, the MP-CPCI was found to be independently associated with CD due to CPD: each 1% increase in MP-CPCI increased the likelihood of CD for CPD by 11% (adjusted odds ratio [aOR] 1.11, 95% CI, 1.03-1.19, p = 0.004). The aOR for CD due to CPD increased incrementally as the MP-CPCI increased, from 3.56 (95% CI, 1.01-12.6) at MP-CPCI of 100 to 5.6 (95% CI, 1.63-19.45) at 105, 21.44 (95% CI, 3.05-150.84) at 110, and 28.88 (95% CI, 2.3-362.27) at MP-CPCI of 115. CONCLUSIONS: The MP-CPCI, representing the relative dimensions of the fetal HC and maternal PC, is a simple tool that can potentially distinguish between parturients at lower and higher risk of CPD. Prospective randomized studies are required to evaluate the feasibility of prenatal pelvimetry and MP-CPCI to predict the risk of CPD during labor.

RESUMEN

OBJECTIVE: To evaluate the predictive value of local versus external cerebroplacental ratio (CPR) reference ranges for delivery outcomes in low-risk pregnancies. METHODS: A retrospective analysis of all feto-maternal demographic and biometric data in fetuses with normal estimated fetal weight (EFW) and a CPR examination between the years 2014-2019, in a university medical center. The study group included healthy singleton pregnancies from 32-week gestation, with an examination-to-delivery interval of <31 days. The three models compared two thresholds: <5th percentile (CPR 1, CPR 3) and <10th percentile (CPR2). The CPR1 and CPR2 models both use local CPR reference ranges, while the CPR3 model uses an external CPR reference range. The main outcome was predictive accuracy for urgent cesarean delivery (CD), operative delivery (OD), and composite outcome (CO), defined as an Apgar score of <7, fetal blood pH < 7.1 or admission to the neonatal intensive care unit (NICU). RESULTS: Overall, 410 low-risk pregnancies with normal weight fetuses were enrolled in the study. All three CPR models turned out to be significant predictors of CD, with an odds ratio (OR) of 9, 95% CI (2.7-27), p < .001 for CPR1, and an OR of 2.9, 95% CI (1.1-7.4), p < .04 for CPR2, and an OR of 3.4, 95% CI (1.7-6.8), p < .001 for CPR3. All the three models were also found to be predictors of OD, and an OR of 6.9, 95% CI (2.1-22) p < .04 for CPR1, and an OR of 2.8, 95% CI (1.2-6.7), p < .04 for CPR2, and an OR of 2.8, 95% CI (1.4-5.3) p < .01 for CPR3. The positive predictive values (PPV) for CD and OD were both 50% for CPR1, versus 28% and 26% in CPR2, and 24% and 25% in CPR3. The negative predictive value (NPV) was similar, around 88% in all three models. None of the models were found to be significant predictors for CO. CONCLUSIONS: A CPR model based on local reference ranges and <5th percentile cutoffs showed the highest PPV for CD and OD. The calculation of local references for CPR should be encouraged.

RESUMEN

BACKGROUND: Iodine is an essential nutrient for human health throughout the life cycle, especially during early stages of intrauterine life and infancy, to ensure adequate neurocognitive development. The growing global reliance on desalinated iodine-diluted water raises the specter of increased iodine deficiency in several regions. The case of Israel may be instructive for exploring the link between iodine status and habitual iodine intake in the setting of extensive national reliance on desalinated water. The aim of this study was to explore the relationship between iodine intake, including iodized salt and iodine-containing supplements intake, and iodine status among pregnant women residing in a sub-district of Israel that is highly reliant on desalinated iodine-diluted water. METHODS: A total of 134 consecutive pregnant women were recruited on a voluntary basis from the obstetrics department of the Barzilai University Medical Center during 2018. Blood was drawn from participants to determine levels of serum thyrotropin (TSH), thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb) and thyroglobulin (Tg). An iodine food frequency questionnaire (sIFFQ) was used to assess iodine intake from food, IS and ICS. A questionnaire was used to collect data on demographic and health characteristics. RESULTS: A total of 105 pregnant women without known or reported thyroid disease were included in the study. Elevated Tg values (≥ 13 µg/L), were found among 67% of participants, indicating insufficient iodine status. The estimated iodine intake (median, mean ± SD 189, 187 ± 106 µg/d by sIFFQ) was lower than the levels recommended by the World Health Organization and the Institute of Medicine (250 vs. 220 µg/day respectively). The prevalence of iodized salt intake and iodine containing supplement intake were 4 and 52% (respectively). Values of Tg > 13 µg/L were inversely associated with compliance with World Health Organization and Institute of Medicine recommendations. CONCLUSIONS: While the Israeli Ministry of Health has recommended the intake of iodized salt and iodine containing supplements, this is apparently insufficient for achieving optimal iodine status among Israeli pregnant women. The evidence of highly prevalent probable iodine deficiency in a sample of pregnant women suggests an urgent need for a national policy of iodized salt regulation, as well as guidelines to promote iodine containing supplements and adherence to them by caregivers. In addition, studies similar to this one should be undertaken in additional countries reliant on desalinated iodine-diluted water to further assess the impact of desalinization on maternal iodine status.

RESUMEN

PURPOSE: This study aimed to assess the rates of retained products of conception (RPOC) after routine postpartum evaluation of patients who underwent post-delivery manual uterine revision due to retained placenta. METHODS: This is a retrospective cohort study of 599 consecutive women who underwent manual removal of placenta during 2010-2018. Group A comprised 465 women who underwent postpartum symptom-based evaluation (2010-2016). Group B comprised 134 women who were routinely evaluated by ultrasound and subsequently by hysteroscopic examination 6 weeks after delivery (2016-2018). RESULTS: The rates of abnormal postpartum bleeding were similar between groups A and B (12% and 13%, respectively, p = 0.72%). A significantly smaller proportion of women underwent hysteroscopy in group A than group B (12% vs. 37%, p < 0.05). The rate of persistent RPOC confirmed by hysteroscopy was significantly lower in group A than group B (9.7% vs. 23%, p < 0.05). CONCLUSION: Among patients who underwent post-delivery manual removal of placenta, a threefold higher rate of RPOC was discovered by routine elective evaluation than by evaluating only symptomatic patients. Future studies may show whether this approach translates to an effect on fertility.

RESUMEN

A uterine inversion occurs when the uterine fundus collapses into the endometrial cavity. It is a rare complication in obstetrics following delivery, and it is even more infrequently encountered in gynecology with the non-puerperal uterus. A submucous fibroid is the most common reported cause of the non-puerperal uterine inversion. If not promptly recognized and treated, uterine inversion may lead to a severe hemorrhagic shock and death. We describe a novel three-dimensional power Doppler feature for the diagnosis of uterine inversion.

RESUMEN

Objective: We aimed to review a single-center experience in follow-up and management of fetuses with umbilical vein varix (UVV) and to assess the effect of UVV on fetal Doppler parameters.Methods: We reviewed retrospectively maternal antenatal records, delivery records, and newborn records to identify cases of UVV. Further, we retrospectively compared 25 fetuses with isolated UVV and available cerebroplacental ratio (CPR) analysis with 75 matched controls.Results: We identified 67 cases of UVV. The median gestational age (GA) at diagnosis was 34 weeks (range: 26-41 weeks). The average diameter of UVV at diagnosis was 10.1 mm (range: 9-14 mm). The median GA at delivery was 36 + 6 (range: 33-41 weeks), with an average birth weight of 2918 g (range: 1278-4140 g). There was a single case of intrauterine death at 35 weeks. CPR was 2.13 ± 0.62 in isolated UVV group compared with 1.84 ± 0.61 in the control group (p < .05). Other Doppler parameters did not differ between fetuses with UVV compared with controls.Conclusions: CPR was significantly increased in the UVV group compared with control fetuses. This finding suggests that UVV is not associated with chronic fetal oxygen deprivation; it, therefore, may contribute to our understanding of the pathophysiology explaining abnormal pregnancy outcome in cases with UVV.

RESUMEN

BACKGROUND: The ratio between the fetal umbilical artery pulsatility index (UA-PI) and the middle cerebral artery pulsatility index (MCA-PI) is termed the cerebroplacental ratio (CPR). The CPR represents fetal blood flow redistribution at the early stages of placental insufficiency; moreover, it has predictive value for adverse intrapartum and neonatal outcomes. However, internationally accepted reference ranges for CPR are lacking. OBJECTIVE: This study sought to establish UA-PI, MCA-PI, and CPR reference ranges in low-risk, normal-growth singleton fetuses during the third trimester of pregnancy. METHODS: A retrospective cohort cross-sectional study was performed in the obstetrics ultrasound unit of a university hospital in Israel. We reviewed all fetal and maternal electronic records of pregnant women referred for ultrasound assessment during the third trimester between January 2014 and January 2019. We included only singleton pregnancies with normal anatomy scans and a normal third-trimester estimated fetal weight. The UA-PI, MCA-PI, and CPR reference ranges were reconstructed for each of the vessels for each gestational age between 29 and 41 weeks. RESULTS: A total of 560 pregnancies met the inclusion criteria. Satisfactory waveforms and measurements were obtained in all cases. At least 18 women enrolled at each gestational week. The MCA-PI and CPR values showed a similar parabolic curve during the third trimester of pregnancy, with a peak value at 32 and 33 gestational weeks, respectively. The UA-PI showed a linear and gradual decrease over the gestational age. CONCLUSIONS: In this study we established UA-PI, MCA-PI, and CPR reference ranges in low-risk, normal-growth singleton fetuses during the third trimester based on the Israeli population.

RESUMEN

BACKGROUND: The sentinel lymph node (SLN) biopsy procedure is a well-known method for identifying solid tumors such as breast cancer, vulvar cancer, and melanoma. In endometrial and cervical cancer, SLN has recently gained acceptance. OBJECTIVES: To evaluate the detection rate of SLN with an indocyanine green and near-infrared fluorescent imaging (ICG/NIR) integrated laparoscopic system in clinically uterine-confined endometrial or cervical cancer. METHODS: Patients with clinically early-stage endometrial or cervical cancer were included in this retrospective study. ICG was injected into the uterine cervix and an ICG/NIR integrated laparoscopic system was used during the surgeries. The National Comprehensive Cancer Network (NCCN) protocol was followed. SLN and/or suspicious lymph nodes were resected. Side-specific lymphadenectomy was performed when mapping was unsuccessful. Systematic lymphadenectomy was completed in patients with high-grade histology or deep myometrial invasion. Enhanced pathology using ultra-staging and immunohistochemistry were performed in all cases. RESULTS: We analyzed 46 eligible patients: 39 endometrial and 7 cervical cancers. Of these, 44 had at least one SLN (93.6%). In 41 patients (89%) we detected bilateral SLN, in 3 (7%) only unilateral, and in 2 (4%) none were detected. Seven patients presented with lymph node metastasis. All were detected by NCCN/SLN protocol. Of these cases, two were detected with only pathological ultra-staging. CONCLUSIONS: SLN mapping in endometrial and cervical cancer can easily be performed with a high detection rate by integrating ICG/NIR into a conventional laparoscopic system. Precision medicine in patients evaluated by SLN biopsy changes the way patients with endometrial or cervical cancer are managed.

RESUMEN

OBJECTIVE: This study sought to compare the short-term outcome of uterine incision repair during a Caesarean section (CS) using a bidirectional knotless barbed suture versus polyglactin suture. METHODS: A randomized controlled trial was conducted at a university hospital. Participants undergoing a CS were randomly assigned to uterine incision closure by bidirectional knotless barbed suture (group A) or polyglactin (group B). The primary outcome was the time needed to repair the uterine incision. The analysis was by intent to treat. A sample size of 35 per group (n = 70) was planned to detect a 30% reduction in uterine repair time (Canadian Task Force Classification I). RESULTS: From July 2016 through October 2017, 150 women were screened, and 70 were statistically analyzed: group A (n = 35) and group B (n = 35). Time to complete uterine incision repair was 308 ± 57 seconds for group A and 411 ± 74 seconds for group B (P < 0.001). Total surgery time (33.4 ± 8.8 minutes vs. 33.2 ± 7.5 minutes; P = 0.64) was not significantly different between groups A and B, respectively. CONCLUSION: Repair of the CS uterine incision with barbed suture compared with polyglactin suture reduces suturing time.

RESUMEN

OBJECTIVE: To quantify the effects of postcesarean section adhesions severity on the incision to delivery time. METHODS: Secondary analysis of data of a prospective randomized controlled trial of women undergoing first repeat cesarean section. The presence and severity of adhesions were reported by surgeons postoperatively and accrued into an adhesion severity score. The primary outcome measure was the correlation between adhesion severity score and incision to delivery time. RESULTS: Of the 97 women analyzed, 47 (48.5%) had an urgent cesarean delivery. Forty-four patients (45.4%) had adhesions. Adhesion score correlated with incision to delivery time (R = .38, p < .01). Patients with adhesions had a significantly longer incision to delivery time (10.3 + 5.9 versus 8.2 = 3.7 minutes, respectively; p = .04). In the Kaplan-Meier analysis, more patients with adhesions remained undelivered at any time point after incision (p = .036). The mean delivery time of patients with adhesion score three was significantly longer in comparison with women with no adhesions (13.0 versus 8.2 minutes, respectively; p = .002). CONCLUSIONS: Post cesarean adhesions delay delivery of the newborn. There is a linear correlation between adhesion severity and the incision to delivery interval.

RESUMEN

OBJECTIVE: To evaluate atrial and ventricular parameters using real time three-dimensional transthoracic echocardiography (RT3DTTE) in women treated with nifedipine in the early third trimester (III-T) of pregnancy. METHODS: A prospective single-subject design study in a university-affiliated hospital, where each participant served as her own control. We studied 25 pregnant women at a gestational age of 25-33 weeks with TPTL prior to vs 48 hours postnifedipine treatment. Two-dimensional transthoracic echocardiography (2DTTE) and RT3DTTE were used to study 3D left atrial (LA) volumes and indexes, emptying fraction, left ventricular and LA cavities, and total vascular resistance (TVR). RESULTS: Two-dimensional transthoracic echocardiography showed a significant increase in LA area (from 15.2 ± 2.62 to 16.16 ± 2.21 mm2 , P = .02) before vs after nifedipine; RT3DTTE showed a significant change in LA end-diastolic volume index (from 23.7 ± 4.2 to 26.75 ± 3.8 mL/m2 , P = .008). LA end-systolic volume and index were not significantly different before vs after nifedipine (from 24.56 ± 8 to 25.3 ± 5.5 mL, from 13.6 ± 5.3 to 14.8 ± 3.4 mL/m2 ); P > .05, respectively. E/a ratio, E-tdi, and E/E-tdi did not change significantly ([from 2.54 ± 4.46 to 2.54 ± 4.1], [from 11.9 ± 1.9 to 11.9 ± 2], [from 7.8 ± 1.4 to 7.6 ± 1.1], respectively, P > .05). Tricuspid annular plane systolic excursion (TAPSE) did not change significantly from 23.77 ± 4.2 to 23.9 ± 3.3, P = .1. There was a significant decrease in pulmonary pressure (from 25.4 ± 4.2 to 23 ± 2.5 mm Hg, P = .02), in mean arterial pressure (from 80 ± 4 to 76 ± 3 mm Hg, P < .001) and in TVR (from 1160 ± 260 to 1050 ± 206 dyne s/cm-5 , P = .04). CONCLUSIONS: According to RT3DTTE measurements, in pregnant women treated with nifedipine for tocolysis, there were no detrimental cardiovascular effects detected 48 hours postnifedipine treatment. RT3DTTE could show accurately the compensatory response of the left heart to the cardiovascular changes induced by treatment with nifedipine.

RESUMEN

PURPOSE: Tubo-ovarian abscess (TOA) is a serious and potentially life-threatening complication of pelvic inflammatory disease (PID). TOA formation may be an uncommon, but serious complication associated with the use of an intrauterine device (IUD). While the majority of TOA respond to antibiotic therapy, in approximately 25% of cases surgery or drainage is indicated. In the present study, we compared the failure rate of conservative management in patients with and without IUD, who were admitted with a diagnosis of TOA. METHODS: In this retrospective case-control study, 78 women were diagnosed with TOA. All patients were treated initially by broad-spectrum intravenous antibiotics. The failure of conservative management after 72 h was followed by surgical intervention. RESULTS: The patients were divided into two groups: 24 patients were IUD-carriers, and 54 did not use IUD. There was no significant difference in surgical intervention rate between IUD group (50%) and no-IUD group (43%), p = 0.32. The WBC count was significantly higher in IUD-carriers diagnosed with TOA than in patients without IUD (16.5 ± 6.6 vs. 13.1 ± 4.6, p = 0.001). The patients with IUD had significantly larger abscesses as revealed by ultrasound than patients without IUD (61.6 ± 21.4 vs. 49.6 ± 20.6 mm, p = 0.02). CONCLUSION: The surgical intervention rate in TOA patients with and without IUD was similar.

RESUMEN

OBJECTIVE: To study whether sonographic findings suggestive of ovarian stromal edema are associated with tissue ischemia in patients with adnexal torsion. METHODS: A study of 79 patients with adnexal torsion was performed. Patients were divided into an ischemic group, in which the twisted adnexa were seen as blue or black, and a non-ischemic group, in which the adnexa retained normal color and appeared viable. Clinical and ultrasonographic findings, specifically the presence of ultrasonographic signs suggestive of ovarian stromal edema, were compared between the two groups. RESULTS: Of the 79 patients with torsion, in 44 (55.7%) the adnexa appeared ischemic at surgery. The presence of ischemia was not associated with age, pregnancy, duration of pain, vomiting or findings at physical examination. There was no significant difference between the ischemic and the non-ischemic group in the proportion of patients with signs of ovarian stromal edema (59 vs. 40%, p = 0.11), in the proportion of patients with absent/diminished stromal Doppler flow (36 vs. 28%, p = 0.12%) or in the proportion of patients with both signs of stroma edema and absent/diminished stromal Doppler flow (20 vs. 12%, p = 0.36). CONCLUSION: Ultrasonographic signs of ovarian stromal edema do not assist in differentiating between ischemic and non-ischemic adnexal torsion.
