Fertility outcomes after preconceptional laparoscopic abdominal cerclage for second-trimester pregnancy losses.

OBJECTIVE(S): Cervical incompetence is an important cause of recurrent pregnancy loss, typically presenting in the second trimester with silent cervical dilation and premature delivery of the fetus. We aimed to evaluate the conception rate and time to conception or failure to conceive after preconceptional laparoscopic abdominal cerclage (LAC). STUDY DESIGN: We conducted this retrospective observational cohort study at a tertiary referral center. Patients who underwent LAC in the nonpregnant state for a second-trimester pregnancy loss between June 2012 and February 2020 were included. RESULTS: The subjects were 40 patients with a history of one or more second-trimester pregnancy losses despite the placement of vaginal cerclage, who had undergone LAC before contemplating a future pregnancy. The mean number of second-trimester pregnancy losses before LAC was two per woman. The ages of the women at the time of cerclage ranged from 21 to 42 years. The time to pregnancy, which was the primary outcome of the study, was determined as the number of menstrual cycles before the patient became pregnant after LAC and the number of cycles needed for the patient to achieve her latest pregnancy before LAC. Of the 40 women, 22.5 % were noted during the LAC operation to have a pelvic peritoneal pathology that might have affected fertility, and all such pathologies were treated concomitantly during the procedure. Spontaneous pregnancy rates before and after LAC were 96.4 % and 89.3 % (p = 0.299), and times to pregnancy before and after LAC were 6.3 ± 8.4 and 6.6 ± 8.1 cycles (p = 0.897). Neither difference was statistically significant. In more than 84 % of patients who became pregnant after LAC, pregnancy was sustained to the stage of viability. CONCLUSION(S): In patients with cervical incompetence, LAC is a very effective intervention to sustain pregnancy to the stage of viability. If placed during the preconceptional period, it does not delay achieving pregnancy and does not have a negative impact on the chances of conception. This may be reassuring to women undergoing this procedure before they achieve a pregnancy.

Prenatally diagnosed case of 22q11.2 deletion syndrome associated with pulmonary artery aneurysm.

Here, we report a new case with chromosome 22q11 deletion and cardiac anomaly diagnosed prenatally by echocardiography. Fluorescence in situ hybridization (FISH) analysis demonstrated a heterozygous deletion at 22q11.2. Echocardiography revealed ventricular septal defect, pulmonary atresia, and aneurysm of the main pulmonary artery and its branches. Pulmonary artery aneurysm (PAA) is rarely seen in patients with 22q11.2 deletion syndrome (22qDS). In this case, PAA was found by prenatal echocardiographic examination at the 25th week of gestation. To date, no prenatally diagnosed case of 22qDS with PAA has been reported. This is the first 22qDS case with PAA that was detected prenatally by FISH analysis.

Rare case of spina bifida in both twins with possible genetic basis.

Neural tube defects (NTD) are a group of congenital malformations of the brain and spine, the etiology of which is still debated. Although presumed to be the consequence of interactions between genetic and environmental factors, so far, it is not known which genes are involved in the pathogenesis of these malformations. NTD affecting both fetuses in a twin gestation is a rare event. In view of this rarity, we present a case of dichorionic diamniotic twin pregnancy with spina bifida in both fetuses concordantly. This gestation was preceeded by another dichorionic diamniotic twin pregnancy that was complicated by placental abruption.

The impact of cervical dilatation on pregnancy outcomes after cerclage placement in women with a short cervical length.

OBJECTIVE: The aim of the study was to compare the outcome of pregnancies with cerclage placement in which cervical length was <15 mm and 15-25 mm. We further investigated the impact of cervical dilatation on delivery at <34 weeks. MATERIAL AND METHODS: Women with singleton gestations with cerclage placement due to cervical insufficiency were enrolled into the study. The data were collected prospectively between September 2004 and February 2009. We divided patients into two categories: (group I) cervical length below 15 mm, (group II) cervical length between 15-25 mm. We compared the pregnancy outcomes of the two groups and also analyzed the independent impact of cervical dilatation on delivery <34 weeks. RESULTS: The cervical cerclage group <15 mm had a similar incidence of preterm delivery <34 weeks gestation to the cerclage group 15-25 mm (p=0.4). No significant difference in rate of neonatal survival (p=0.6) was found between the two groups. Increased cervical dilatation in centimeters was found to be a significant predictor of delivery before 34 weeks gestation (OR: 3.4, 95% CI: 1.3-8.5, p=0.009). CONCLUSIONS: The extent of cervical shortening did not have a significant independent effect on the perinatal outcome of patients with cerclage placement. However, the presence of cervical dilatation prior to cerclage placement in cases of cervical insufficiency may worsen perinatal outcomes by increasing the rate of delivery before 34 weeks.

Transient osteoporosis of pregnancy: case report.

Transient osteoporosis of pregnancy is a rarely observed skeletal pathology developing in the last months of pregnancy. Meticulous evaluation is important for the differential diagnosis of severe and progressive hip and/or groin pain in pregnant patients. MRI is a valuable and safe technique for demonstrating bone marrow edema and skeletal abnormalities during pregnancy. Avoidance of vaginal delivery and non-weight bearing measures are essential in order to prevent complications such as hip fractures related to transient osteoporosis of pregnancy. We present the diagnostic evaluation and treatment of an uncommon case of transient osteoporosis of pregnancy with resolution of symptoms and postpartum.

Intracranial injection with KCl: an alternative method in selected cases of multifetal pregnancy reduction.

Multifetal pregnancy reduction (MFPR) offers a therapeutic option which reduces the maternal, prenatal, neonatal morbidity and mortality associated with multifetal pregnancies. In certain cases of MFPR, where difficulty is encountered in reaching the thorax due to the fetal position as well as the location of membranes and placenta, an alternative approach may be the insertion of the needle to the fetal cranium. We describe a new technique for MFPR performed by fetal intracranial injection of potassium chloride. To our knowledge, the current case series is the first report describing the technique of intracranial injection of potassium chloride during MFPR and selective termination. This approach enables a technically easier procedure than the intrathoracic approach. However, the use of this technique should be reserved for selected cases of MFPR only by experienced operators and centers.

Laparoscopic management of heterotopic cesarean scar pregnancy with preservation of intrauterine gestation and delivery at term: case report.

OBJECTIVE: To present a case of laparoscopic removal of a heterotopic cesarean scar pregnancy under ultrasound guidance. DESIGN: Case report. SETTING: Private hospital. PATIENT(S): A 34-year-old woman with heterotopic cesarean scar pregnancy. INTERVENTION(S): Laparoscopic removal of heterotopic cesarean scar pregnancy. MAIN OUTCOME MEASURE(S): Delivery at term after laparoscopic management of heterotopic cesarean scar pregnancy. RESULT(S): An ongoing intrauterine pregnancy ended with a live birth after successful removal of the heterotopic gestational mass by a laparoscopic approach. CONCLUSION(S): Surgical removal of the ectopic mass by laparoscopy may be a radical approach in cases of heterotopic cesarean scar pregnancy. Laparoscopic excision of the cesarean scar pregnancy gives the opportunity to preserve the viable intrauterine gestation while maintaining a strong lower uterine segment. Ultrasound is an adjunctive tool that enables precise location of the ectopic mass during the operation.

Non-invasive management of fetal goiter during maternal treatment of hyperthyroidism in Grave's disease.

There is an increased risk of fetal goiter in patients who have a history of Grave's disease and undergo propylthiouracil (PTU) treatment during pregnancy. In this report, we describe a case of a fetal goiter detected by antenatal ultrasound at the 26th week of gestation in a mother treated with PTU for Grave's disease. A 32 x 38 x 20 mm fetal goiter was detected, each lobe measured 30 x 18 x 18 mm and estimated volume was 10 cm3. Subsequently, fetal thyroid function was assessed by umbilical fetal blood sampling. Cord blood showed elevated serum TSH (40.2 mU/l) and normal concentrations of free T4 (9.5 pmol/l) and free T3 (2.6 pmol/l). There were no other ultrasonographic signs of fetal hypothyroidism. Based on the above findings, the mother's PTU dosage was reduced to 50 mg daily from a total of 150 mg and weekly ultrasonographic examinations were performed. Six weeks after the initial ultrasound, a complete regression of the fetal goiter was noted. At the 34th week of gestation, the patient was delivered due to intrauterine growth restriction and oligohydramnios and gave birth to a male, weighing 1,920 g. The newborn thyroid was not palpable and thyroid ultrasonography was normal. Cord blood TSH was normal (8.4 mU/l) and free T4 was within lower normal limit (9.03 pmol/l). Ten days later, newborn thyroid function was normal and the baby did well afterwards. In conclusion, after the evaluation of fetal thyroid status, selected cases with fetal goiter can be initially managed without intrauterine treatment.

Prenatal diagnosis of a partial monosomy 7q11-->q31 in a fetus with split foot.

OBJECTIVE: A 27-year-old woman was referred to our laboratory for genetic counseling at 26 weeks of gestation due to abnormal ultrasound findings including intrauterine growth retardation, Dandy-Walker malformation and lower extremity anomalies. METHODS: Chromosome analysis was performed on fetal blood sample obtained by cardiocentesis. RESULT: We observed an abnormal karyotype with a structural abnormality of the long arm of chromosome 7. Both parents' chromosomes were normal; thus, the fetal karyotype designation was 46,XX, del(7)(pter-->q11::q31-->qter) de novo. Skin biopsy sample was taken to confirm the karyotype after therapeutic abortion was performed. The result was identical. Postmortem examination and autopsy showed facial dysmorphism, malformations of the lower extremities and central nervous system anomalies. CONCLUSION: 7q interstitial deletions cause a wide spectrum of congenital abnormalities and syndromes linked to the deleted segments. Our case had a rather wide chromosome region deleted and it is important, because prenatal diagnosis was performed. Thus, the family had the chance to evaluate the situation and decided to terminate the pregnancy after genetic counseling.

Spontaneous regression and reaccumulation of pleural effusion in a fetus. A case report.

Isolated pleural effusion is rare and occurs when varying degrees of fluid surround the fetal lung without concomitant hydrops. The effusion may regress spontaneously, remain stable in size, or progress to involve both sides of the chest causing fetal hydrops. This may result in pulmonary hypoplasia and fetal or neonatal demise. In this article, we report a case in which spontaneous resolution of an isolated right-sided fetal pleural effusion occurred at 23 weeks of gestation and reappeared bilaterally at 34 weeks. Serial ultrasonographic evaluation of the fetus should be continued even if a spontaneous resolution of a preexisting pleural effusion has occurred.

Prenatal diagnosis of multiple pterygium syndrome associated with Klinefelter syndrome.

A nonlethal form of multiple pterygium syndrome (MPS) was diagnosed prenatally at 16 weeks of gestation with associated Klinefelter syndrome in the same fetus. The ultrasound findings were cystic hygroma, hypertelorism, micrognathia, low-set ears, flexion contractures of upper and lower extremities and rocker-bottom foot. Genetic amniocentesis revealed a 47,XXY karyotype. After genetic counseling, the parents decided to have a therapeutic abortion. We presented this case for the purpose of further describing the early ultrasound findings and clinical features of multiple pterygium syndromes. Also, what makes our patient unique is the coincidental presence of Klinefelter syndrome with MPS. To our knowledge, this is the first case in the literature in which a 47,XXY karyotype has been found in a fetus with multiple pterygium syndrome. The importance of delineating the exact subtype of MPS and making a precise differential diagnosis becomes critical during the process of evaluation of patients with MPS.

Meconium enhances the growth of perinatal bacterial pathogens.

OBJECTIVE: To demonstrate the effects of meconium on growth of bacterial pathogens, which are common causes of intra-amniotic infection and neonatal sepsis. METHODS: Meconium collected from 9 healthy neonates was suspended as a 20% solution using sterile saline. In experiment 1, separate test tubes of meconium solution and sterile saline (the control) were individually inoculated with 10(6) colony-forming units of a single species of the following test pathogens: Escherichia coli, Enterococcus faecalis, Group B Streptococcus, Staphylococcus aureus, Pseudomonas aeruginosa, and Listeria monocytogenes. After incubation at 37 degree C for 24 hours, 1 L each of the bacterial-meconium and bacterial-saline solutions was inoculated onto 5% sheep blood agar. After 24 hours of incubation, the number of developing colonies was counted. In experiment 2, equal volumes of meconium and saline solutions were inoculated with 10(5) colony-forming units of either E. coli or Group B Streptococcus. At intervals of 6, 9, and 24 hours post-incubation, 1 L each of the bacterial-meconium and bacterial-saline solutions was inoculated onto 5% sheep blood agar plates, and colonies were counted after overnight incubation. RESULTS: In the first experiment, 24 hours of incubation resulted in bacterial amplification in the meconium solution from an initial inoculum of 10(6) colony-forming units/mL to 10(9) colony-forming units/mL. In contrast, the same inoculation of saline solution (control) showed no increase in colony counts over the same time interval. For E. coli and Group B Streptococcus in experiment 2, growth enhancement in meconium was seen as early as 6 hours, as colony counts of a test species increased from 105 colony-forming units/mL to 10(9)-10(10) colony-forming units/mL. CONCLUSION: Enhanced growth of perinatal pathogens in meconium was constantly observed, and can occur as early as 6 hours after bacterial interaction of meconium.

New rapid bed-side test to predict preterm delivery: phosphorylated insulin-like growth factor binding protein-1 in cervical secretions.

BACKGROUND: Phosphorylated insulin-like growth factor binding protein-1 (phIGFBP-1) is secreted by decidual cells and leaks into cervical secretions when fetal membranes detach from decidua. Our aim was to assess whether detection of phIGFBP-1 in cervical secretions by a rapid bed-side test could be used to predict preterm delivery in patients with regular uterine contractions. STUDY DESIGN: In our prospective study, 36 women between 20 and 36 weeks of gestation with regular, persistent contractions (> 10/h) and 18 women between 20 and 36 weeks gestation without symptoms of preterm labor were assessed for the presence of cervical phIGFBP-1. Dacron swabs were applied to the cervix and assayed in 5 min by using immunochromotography, a new rapid bed-side test (actim partus test, Medix Biochemica, Kauniainen, Finland). Data analysis included one-way variance analysis (ANOVA), Student's t-test, chi-square and Fisher's exact test. RESULTS: Of the 36 patients with regular uterine contractions, 18 had a positive actim partus test and 18 had a negative test. Among the 18 patients with a positive test, only one delivered term and the other 17 patients delivered preterm (< 37 weeks). Among the 18 women with a negative test, only two delivered preterm (p < 0.05). Mean gestational age at delivery for patients with a positive and a negative test was 34.4 +/- 3.0 and 37.9 +/- 2.3 weeks, respectively (p < 0.05). Sensitivity, specificity, positive and negative predictive values of the rapid phIGFBP-1 test for preterm delivery was 89.5, 94.1, 94.4 and 88.9%, respectively. For delivery < 37 weeks, positive likelihood ratio was 15.2 (+/- 95% CI; range 2.6-102.5). When cervical phIGBP-1 assay was used to predict delivery within 7 days, sensitivity, specificity, positive and negative predictive values were 93.8, 85%, 83.3 and 94.1%, respectively. Positive likelihood ratio with +/- 95% CI was 6.25 (range 2.2-17.8). When patients were categorized according to cervical dilatation, the positive likelihood ratio of the test when the cervix was closed at 2 cm were 8.3 (1.3-55.3), 13.6 (2-91.4), 15.8 (2.3-106.3) and 1.5 (0.2-11.5), respectively, CONCLUSION: The presence of cervical phIGFBP-1 is predictive of preterm delivery < 37 weeks of gestation. Our study shows that cervical detection of phIGFBP-1 by immunochromotography is a rapid and easily applicable test that highly anticipates preterm delivery in patients at risk.

Maternal-fetal factors that affected Doppler waveform analysis in a patient undergoing hemodialysis.

Pregnancy in women having chronic renal insufficiency and undergoing hemodialysis is a rare event with a poor outcome. This is the 1st case in whom pre- and posthemodialysis fetal renal artery Doppler flow velocimetry was used in conjunction with fetal blood sampling which was performed to assess fetal karyotype and blood chemistry. Uteroplacental Doppler measurements were also performed, and a close correlation between maternal-fetal blood creatinine and urea nitrogen levels and fetal renal, umbilical, and uterine artery resistance indexes was observed.

Does insulin secretion in patients with one abnormal glucose tolerance test value mimic gestational diabetes mellitus?

OBJECTIVE: The purpose of this study was to investigate the insulin response to a 3-hour oral glucose tolerance test and to compare the insulin levels in the gestational diabetes mellitus and single abnormal test value groups with a nondiabetic control group. STUDY DESIGN: One hundred ten Turkish women with uncomplicated pregnancy participated in this prospective controlled study between 24 to 28 weeks of gestation. A 100-g 3-hour oral glucose tolerance test was given, and glucose and insulin plasma levels were assayed. The subjects were classified according to established criteria. Early-phase insulin secretion was assessed by the insulinogenic index. Total insulin secretion was assessed by mean insulin level during the oral glucose tolerance test; insulin resistance was assessed by fasting insulin concentration and by the use of the homeostasis model. Data were analyzed by the Student t test and 1-way analysis of variance, with posthoc Bonferroni correction. RESULTS: The fasting insulin levels of patients with normal oral glucose tolerance test results were significantly lower than those of patients with gestational diabetes mellitus and a single value abnormality (P <.001 and P <.005, respectively). The insulinogenic index as a marker of early-phase insulin secretion was significantly lower in gestational diabetes mellitus, compared with that of patients with normal oral glucose tolerance test results (P <.05). The worsening of glycemic profile from normal oral glucose tolerance test results to gestational diabetes mellitus was associated with an increase in the homeostasis model; no significant difference was found between gestational diabetes mellitus and a single value abnormality group in terms of both the homeostasis model and the insulinogenic index. Values for total insulin secretion were highest in gestational diabetes mellitus, followed by the single value abnormality group, both significantly differing from the values of patients with normal oral glucose tolerance test results (P <.001 and P <.005, respectively). CONCLUSION: In this prospective study of Turkish subjects, we found a striking similarity in terms of patient characteristics between the gestational diabetes mellitus group and the single value abnormality group. Additionally, when we used fasting insulin level and insulin resistance as 2 separate criteria of analysis, patients with single value abnormality were indistinguishable from patients with gestational diabetes mellitus; both groups were significantly different from the normal oral glucose tolerance test group. Our findings suggest that a single abnormal test value on an oral glucose tolerance test should be regarded as a pathologic finding and that the patient with a single abnormal test value may be treated similarly to the patient with gestational diabetes mellitus.
