RESUMEN
BACKGROUND: Despite technological advancements in perinatal imaging, autopsy examination is still regarded as the reference standard to determine the time and reason of the fetal death. PURPOSE: This study was conducted to identify the intrauterine postmortem magnetic resonance imaging (PMMR) findings of fetuses, who underwent radiofrequency ablation (RFA). STUDY TYPE: Prospective. POPULATION: Fifty-three twin/triplet complicated pregnancies scheduled for selective reduction of one of the fetuses by RFA were included. FIELD STRENGTH/SEQUENCE: The imaging methods used are T1-weighted gradient-echo imaging (T1 GRE), T2 half-Fourier acquisition single-shot turbo spin-echo (SSTSE), and diffusion-weighted imaging (DWI) sequences. ASSESSMENT: The MRIs were interpreted by three radiologists. STATISTICAL TESTS: Data were analyzed using the software package SPSS Statistics Version 22.0. The used tests included one-way analysis of variance (ANOVA) and Duncan tests (significance level: P value <0.05). This analysis was performed with scikit-learn library (version 1.1.1) in Python version 3.9. RESULTS: Average PMMR scores of orbit, brain, and abdomen showed significant differences among different PM interval subgroups. The brain apparent diffusion coefficient (ADC) numbers of reduced and living fetuses were significantly different at any PM interval. To determine which findings are closely associated with the timing of fetal death, five different methods of feature selection were employed. The top eight selected features achieved the highest area under the curve (AUC) of 78.19%. DATA CONCLUSION: In utero, PMMR findings may be associated with the time of fetal death. Among different fetal organs evaluated, particularly PMMR top eight features specifically scores of orbits were associated with PM intrauterine time after death. LEVEL OF EVIDENCE: 2 TECHNICAL EFFICACY: Stage 2.

Purpose: We aimed to provide diagnostic models based on different parameters of placental magnetic resonance imaging (MRI) to detect intrauterine growth restriction (IUGR), as well as the severity of placental insufficiency. Material and methods: We included 44 foetuses with appropriate weight for gestational age (AGA) and 46 foetuses with documented IUGR, defined as the estimated foetal weight (EFW) below the 10th centile. Using Doppler ultrasound, IUGR cases were divided into 2 groups: 1) IUGR with severity signs: EFW < 3rd centile, or cerebroplacental ratio < 5th centile, or abnormal umbilical/uterine artery pulsatility index; and 2) non-severe IUGR without any of this criterion. For all these participants, placental MRI was performed in the third gestational trimester, and its parameters were compared between AGA and IUGR, as well as between the severe and non-severe IUGR groups. Two diagnostic models consisting of significant predictors were developed, and their performance was investigated with accuracy metrics. Results: The severity signs were detected in 25 (54.3%) IUGR cases. The diagnostic model for the differentiation of IUGR from AGA revealed an acceptable performance (area under the curve [AUC] of 0.749) and consisted of 2 variables: 1) the largest size of infarct ≥ 25 mm (odds ratio [OR] = 5.01, p = 0.001), and 2) thickness : volume ratio ≥ 0.043 (OR = 3.76, p = 0.027); while, the logistic regression model for detection of the severity signs was even better, with AUC = 0.862, and comprised of 2 predictors: 1) placental infarct percent ≥ 10% (OR = 26.73, p = 0.004), and 2) placental globular shape (OR = 5.40, p = 0.034). Conclusions: Placental MRI parameters can differentiate IUGR from AGA, and more precisely, assess the severity of placental insufficiency in IUGR foetuses.
RESUMEN
OBJECTIVE: This systematic review and meta-analysis aimed to compare the perinatal outcomes of complicated monochorionic pregnancies after selective reduction by radiofrequency ablation, bipolar cord coagulation, and interstitial laser. DATA SOURCES: We searched PubMed, Scopus, and Web of Science, from the inception of the database up to April 26, 2021. STUDY ELIGIBILITY CRITERIA: Studies comparing at least 2 selective reduction techniques among complicated monochorionic pregnancies and presenting data on perinatal outcomes, including gestational age at procedure, gestational age at delivery, procedure to delivery interval, preterm premature rupture of membranes, preterm birth, survival rate, and birthweight, were eligible. METHODS: The random-effects model was used to pool the mean differences or odds ratios and corresponding 95% confidence intervals. Heterogeneity was assessed using the I2 value. RESULTS: A total of 10 studies with 734 cases of fetal reduction met the inclusion criteria, of which 9 studies with 674 fetuses were eligible for quantitative synthesis. In 8 studies that compared radiofrequency ablation with bipolar cord coagulation, radiofrequency ablation was associated with increased procedure to delivery interval (days) (mean difference, 13.42; 95% confidence interval, 1.90-24.94; P=.02; I2=0.0%), decreased preterm birth (odds ratio, 0.50; 95% confidence interval, 0.29-0.85; P=.01; I2=3.0%), and decreased preterm premature rupture of membranes (odds ratio, 0.45; 95% confidence interval, 0.27-0.73; P=.001; I2=0.0%). Radiofrequency ablation and bipolar cord coagulation had comparable survival rates (odds ratio, 0.85; 95% confidence interval, 0.54-1.35; P=.49; I2=0.0%). In 3 studies that compared radiofrequency ablation with interstitial laser, there was no significant difference in gestational age at delivery (P=.07) or survival (P=.15). In 3 studies that compared bipolar cord coagulation with interstitial laser, bipolar cord coagulation was associated with a higher survival rate (odds ratio, 3.21; 95% confidence interval, 1.13-9.10; P=.03; I2=0.0%), but the gestational age at delivery was comparable between groups (P=.16). CONCLUSION: This study demonstrated that radiofrequency ablation has a greater procedure to delivery interval and decreased preterm premature rupture of membranes and preterm birth than bipolar cord coagulation. Although there was no difference in gestational age at delivery for either bipolar cord coagulation, radiofrequency ablation, or interstitial laser, survival was higher with bipolar cord coagulation than with interstitial laser.

BACKGROUND: This study aimed to investigate the additional advantages of magnetic resonance imaging (MRI), particularly diffusion-weighted imaging (DWI) over fetal ultrasound in the detection of acute ischemic cerebral injuries in complicated monochorionic (MC) pregnancies that underwent selective reduction by radiofrequency ablation (RFA). METHODS: This prospective cohort study was conducted on 40 women with complicated MC pregnancies who were treated by RFA. Fetal brain imaging by DWI and conventional MRI was performed either in the early (within 10 days after RFA) or late phase (after 3-6 weeks) in the surviving fetuses to detect both acute and chronic ischemic injuries. The presence of anemia after RFA was also evaluated by Doppler ultrasound. RESULTS: Overall, 13 of the total 43 fetuses (30.23%) demonstrated MRI abnormalities with normal brain ultrasound results including germinal matrix hemorrhage (GMH), extensive cerebral ischemia, and mild ventriculomegaly. Although seven fetuses with GMH eventually survived, fetuses that demonstrated ischemic lesions and ventriculomegaly on MRI died in the uterus. CONCLUSION: The absence of abnormal cerebral lesions or anemia on ultrasound and Doppler exams does not necessarily rule out fetal brain ischemia. Performing early MRI, particularly DWI seems to be a reasonable option for detection of early intracranial ischemic changes and better management of complicated multiple pregnancies which were treated by RFA.

The corpus callosum (CC) is the major interhemispheric commissure and its abnormalities include agenesis, hypoplasia, and hyperplasia. The CC anomalies are typically related to other central nervous system (CNS) or extra-CNS malformations. The antenatal diagnosis of complete CC agenesis is easy after mid-trimester by ultrasound (US) even in the axial plane. The non-visualization of cavum septum pellucidum and colpocephaly are critical signs in the axial view. More subtle findings (i.e., hypoplasia and partial agenesis) might also be recognized antenatally. In this review, the focus was given on the prenatal diagnosis of CC abnormalities in US and magnetic resonance imaging.

Predicting late-onset foetal growth restriction (FGR) has proven to be rather challenging. In this study, we propose a new parameter, cerebral-placental-uterine (CPU) ratio and umbilico-cerebral (UC) ratio for this matter. Results of this study which included a total of 227 nulliparous women showed that an increase in CPU ratio (OR = 0.45; 95% CI: 0.23-0.88; p=.020) was associated with lower odds of foetal weight above the 10th percentile at birth. CPU ratio measured at 35-37 weeks of gestation had an AUC of 0.78 (95% CI: 0.58, 0.98), sensitivity of 0.62 (95% CI: 0.24, 0.91) and specificity of 0.90 (95% CI: 0.79, 0.96) for prediction of late-onset FGR, which showed higher accuracy than UC ratio. As some cases of the late-onset FGR are not diagnosed by foetal biometry, it is important to find Doppler parameters that can help us predict these cases and CPU ratio may help physicians in detection of high-risk foetuses that will benefit from earlier intervention. Impact StatementWhat is already known on this subject? Late-onset foetal growth restriction (FGR) defined by an FGR diagnosis after 32 weeks of gestational age, can lead to short- and long-term morbidities and early diagnosis is the key to prevent these complications.What do the results of this study add? Results showed that each unit increase in numeric variables including CP ratio (OR = 0.29, p=.006), and CPU ratio (OR = 0.40, p=.006) was associated with lower odds of the foetal weight above the 10th percentile in the second ultrasound at 35-37 weeks. In other words, CPU ratio can prove to be useful marker in prediction of late-onset FGR.What are the implications of these findings for clinical practice and/or further research? Our prospective cohort study confirms the added value of low CPU ratio, with higher predictive accuracy than UC ratio, in predicting late-onset FGR. Detection of late FGR remains poor, but it is important to prevent stillbirth so further studies on the role of CPU ratio in predicting FGR and perinatal outcomes are needed.

BACKGROUND: To evaluate the perinatal outcomes in women with complicated monochorionic diamniotic twins who underwent selective reduction using radiofrequency ablation (RFA). METHODS: This retrospective study included patients with complicated monochorionic diamniotic twins between 16 to 28 weeks who underwent selective reduction using RFA. RESULTS: During the study period, 143 women with complicated monochorionic twins underwent RFA including 52 with selective fetal growth restriction (sFGR), 48 with twin to twin transfusion syndrome (TTTS), 33 with major fetal anomalies in one of the twins, and 10 with reversed arterial perfusion sequence (TRAP). The overall survival was 71.3% (102/143). The procedures were technically successful in achieving selective termination in all cases. The mean ± SD of gestational age at the time of the procedure was 21.0 ± 2.3 weeks. The mean ± SD of gestational age at delivery was 34.6 ± 3.3 weeks. The mean ± SD of overall procedure-to-delivery time was 12 ± 1.7 weeks. The pregnancy success rates among sFGR, TRAP, TTTS and anomaly groups were 82.7, 80, 73 and 60.7% respectively. There were no maternal complications. CONCLUSION: Radiofrequency ablation for fetal reduction in complicated monochorionic twin pregnancies appears to be a reasonable option. The pregnancy success rate following RFA selective reduction was highest among sFGR and TRAP groups and lowest in the anomaly group.

INTRODUCTION: Inappropriate request for laboratory tests is a challenging problem and an important cause for additional healthcare costs. Indeed, it may have further ambiguity for the clinicians. This study aimed to design an education-based program to reduce unnecessary laboratory testing orders and the associated costs. MATERIALS AND METHODS: In this interventional prospective study that took place in an educational hospital, the type and frequency of selected laboratory testing requested by gynecology, and obstetrics residents in the patients with gestational diabetes mellitus, preeclampsia, preterm labor, and premature preterm rupture of the membrane as well as cesarean section and normal vaginal delivery were analyzed periodically in a 1-year interval. At the same time, continuous educational supports and monitoring were performed. The results were compared before and after interventions. RESULTS: The educational intervention regardless of the etiologies of the admission, decreased the requested laboratory testing significantly (p < 0.001), except for CBC. Indeed, no near misses or delays in treatment were observed. Cost analysis showed a 31.3% reduction of expenses per inpatient day due to the decrease in the number of daily laboratory testing ordered. CONCLUSIONS: Appropriate education and continuous monitoring of the residents could reduce the unrequired laboratory testing as well as healthcare costs.

BACKGROUND: Thromboembolism is one of the main causes of maternal mortality, which can be prevented in many cases. The present study was designed to investigate the incidence and prophylaxis strategies for maternal mortality following thromboembolism in postnatal. METHODS: In this case series study, the data of the mortality cases were extracted according to the ethical and security standards of the Ministry of Health of the country and compared with a healthy control group. The thromboembolism risk factors measured and scored using a questionnaire entitled "the evaluation of risk factors for maternal mortality following thromboembolism during pregnancy, labor, or post-partum". RESULTS: The maternal mortality rate was 16 per 100,000 live births. Among 297 mortality cases, 27 (9%) death were due to thromboembolism. The mean gestational age was 32.5 weeks. Dyspnea (88.8%) and tachycardia (18.5%) were found as common clinical manifestations in these patients. Sixteen cases (59.3%) did not get heparin, 6 (22.2%) received single dose and 5 (18.5%) received two doses and more. In these 11 cases, 5 (45%) patients received heparin before surgery, 1 after surgery, and 5 before and after surgery. Twenty cases deceased in the first hours after delivery and the rest after 2 to 12 days. The average score of risk for thromboembolism based on Royal College of Obstetricians & Gynecologist (RCOG) guideline was 4.6. CONCLUSION: It seems that one of the most important cause of maternal mortality in this study was the lack of recognition of high-risk patients and the lack of prescription for prophylaxis with heparin and this clearly explains the need for accurate screening of high-risk mothers, designing a standard form and the care and treatment of these patients.
RESUMEN
BACKGROUND: Peptic ulcer perforation in the early post-cesarean period is rare but may result in maternal mortality. CASE PRESENTATION: Four cases of post-cesarean peptic ulcer perforation are presented. In all four patients, presentations include peritoneal signs such as acute abdominal pain and progressive distention, hemodynamic instability and intraperitoneal free fluid by ultrasound. Laparotomy and repair were done in all 4 cases. There were 2 maternal deaths. We also have reviewed English literature for the similar cases reported from 1940 to March 2019. CONCLUSION: New onset tachycardia, abdominal pain and progressive distension after cesarean section without congruent changes in hemoglobin should raise concerns for intra-abdominal emergencies including perforated peptic ulcer. Early use of ultrasound should be considered to assist in diagnosis. Coordinated care by an obstetrician and a general surgeon is necessary in presence of any unusual postoperative abdominal pain. Early recognition of the disease is imperative to limit the surgical delay and to improve the outcomes.

PURPOSE: This study aimed to compare the apparent diffusion coefficient (ADC) values of different brain areas between two groups of intrauterine growth restricted (IUGR) foetuses and control cases. MATERIAL AND METHODS: A total of 38 foetuses with IUGR and 18 normal control foetuses with similar gestational age were compared using a 3T magnetic resonance scanner. IUGR cases included 23 foetuses with clinical severity signs (group A) and 15 foetuses without clinical severity signs (group B). ADC values were measured in different brain regions and compared among groups. Foetuses with structural brain abnormalities were excluded from the study. RESULTS: All foetuses had normal foetal structural brain anatomy. Head circumference (HC) < 5% was more common in IUGR group A compared to IUGR group B (56.5% vs. 13.3%, p < 0.0001). In comparison to the normal group, the ADC values in IUGR foetuses were significantly lower in cerebellar hemispheres (CH) (1.239 vs. 1.280.5 × 10-3 mm2/s, p = 0.045), thalami (1.205 vs. 1.285 × 10-3 mm2/s, p = 0.031) and caudate nucleus (CN) (1.319 vs. 1.394 × 10-3 mm2/s, p = 0.04). However, there were no significant differences in ADC values between IUGR subtypes. Among all brain regions, pons had the lowest ADC values. CONCLUSIONS: ADC values of thalami, CN, and CH were significantly lower in IUGR than control foetuses, while there was no significant difference among IUGR groups. Further studies are needed to evaluate the prognostic value of ADC changes in IUGR foetuses.
RESUMEN
The goal of the current study was to evaluate the efficiency of a phytotherapeutic intervention consisting of a combination of Nigella sativa and Vitex agnus-castus with citalopram in the control of hot flashes in healthy menopausal women. An 8 week, double-blind, randomized, placebo-controlled study was performed among 46 women aged between 40 and 60 years experiencing an average of more than four hot flashes per day recruited during July 2016 to June 2017. Data on severity of vasomotor symptoms were collected at the end of the eighth week. Herbal medication or placebo capsules were administered once daily in morning. At the end of the 8-week treatment period, analyses of covariance demonstrated the superiority of herbal combination with citalopram over placebo and citalopram for three MENQOL domain scores including vasomotor (p < .001), physical (p = .036), psychosocial (p = .001) but no significant differences were observed in terms of sexual function (p = .231). Based on the results, the addition of a combination of N. sativa and V. agnus-castus to the citalopram may be a potential clinical application for improving therapeutic outcomes. Larger randomized, controlled trials are also warranted for further investigations of these symptoms.

BACKGROUND: This study was conducted to compare neonatal complications in scheduled cesarean sections (CS) between 38 and 39 gestational weeks with CS performed after 39 gestational weeks in Iranian low -risk pregnant women. METHODS: In this cohort study, 2086 patients were enrolled based on the inclusion and exclusion criteria. The neonates were evaluated in terms of the following items: transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), sepsis, need for NICU hospitalization, birth weight, birth height, head circumference, and the first minute and fifth minute Apgar score. Several multiple logistic regression models were performed for each response variable (adverse outcome) separately. RESULTS: The incidence of NICU admission was significantly higher in neonates born at 38-39 gestational weeks than those who were born after 39 gestational weeks. No significant differences were found in the incidence of neonatal sepsis, TTN, and RDS between the two groups. CONCLUSION: According to our study results, elective CS at 38-9 weeks' gestation is associated with a higher rate of TTN and NICU admission in comparison with elective CS performed after 39 completed gestational weeks.

BACKGROUND: The admission test (AT) has been carried out for many years, but there are still debates about the prognostic value of the test. Therefore, we aimed to examine the value of the AT in predicting the adverse outcome in neonates. METHODS: In this cross-sectional study, 425 pregnant women with normal vaginal delivery were studied between2009 and 2014at Vali-e-Asr Hospital. Based on the results, the women were divided into 2groups of normal and abnormal ATs. All the patients were followed up until the birth of their baby, when the status of mother and neonate was determined. The main outcomes of the study were cesarean rate, neonatal intensive care unit (NICU) admission, fetus demise, neonatal acidosis, and Apgar score. The independent t-test, chi-square test, Fisher exact test, and logistic regression were used for statistical analysis. The data were analyzed using SPSS (version 17). RESULTS: Of 425 pregnant women studied, 142 (33.4%) had abnormal ATs with a mean age of 29 (±4.5) years. Multivariate analysis showed that an abnormal AT was able to predict the incidence of cesarean section, intrauterine growth restriction, turned cord, and Apgar<7, but it could not predict neonatal death and hypoxia. CONCLUSION: The AT was shown to be a useful screening test with risk factors such as oligohydramnios, bloody amniotic fluid, meconium amniotic fluid, intrauterine growth restriction, and turned cord. Additionally, the test was also able to predict NICU admission and the need for cesarean section, but it could not predict the occurrence of neonatal death.
RESUMEN
INTRODUCTION: Sleep disturbance is a common complaint in postmenopausal women. Few studies compared symptom improvement taking antidepressants versus placebo. This study aims to evaluate the efficacy of venlafaxine and Citalopram compared to placebo in treatment of sleep disturbance in healthy postmenopausal women. METHOD: This randomized, double-blind, placebo-controlled clinical trial was conducted in three groups of 20 postmenopausal women. The patients took venlafaxine 75 mg/daily (group I) or citalopram 20 mg/d (group II) or placebo (group III). Each patient filled Pittsburgh sleep quality index (PSQI) and Pittsburgh and Beck depression questionnaires. The frequency of hot flashes in a day and its severity were measured through diaries. Somatic symptoms and adverse side effects were evaluated. Follow-up visit was conducted after 3 months. The prior and the later results were compared. RESULTS: The PSQI scores in three placebo, venlafaxine, and citalopram groups before treatment were 14.25 ± 3.85, 11.55 ± 3.96, and 13.50 ± 3.56, respectively (p = 0.076). These values after treatment reached 9.95 ± 5.07, 8 ± 3.06, and 6.95 ± 1.84, respectively. PSQI score in citalopram and venlafaxine group was not significantly different (p = 0.19) but the score in both groups was significantly lower compared with placebo group after treatment (p = 0.01). The frequency of hot flashes in a day was reduced significantly by both citalopram and venlafaxine (p < 0.05), although it was more reduced by citalopram than venlafaxine (p = 0.03). Severity of hot flashes in both venlafaxine and citalopram was significantly lower in comparison with placebo group (p = 0.02), and there was no significant difference between two drugs, though (p = 0.84). Beck score decreased more in venlafaxine group in comparison with other groups but it did not reach significant (p = 0.06). CONCLUSION: Citalopram and venlafaxine are equally more effective than placebo in reducing sleep disturbance and severity of hot flashes, while citalopram is more effective in reducing frequency of hot flashes than venlafaxine. Meanwhile, venlafaxine is more effective than citalopram in treatment of depression in postmenopausal women. TRIAL REGISTRATION: Iranian Registry of Clinical Trials 201210152576N6.

Isotretinoin is a drug used for treating severe cystic/nodular acne. Severe malformations have been documented in neonates whose mothers had taken isotretinoin during pregnancy. Women who became pregnant one cycle after completing therapy are believed to be at teratogenic risk not higher than baseline. We describe the case of a newborn whose mother had taken the drug for 4 weeks. The woman then had contraception for 4 weeks (after the drug treatment had finished), and became pregnant after that period. The newborn had isolated bilateral microtia due to suspected isotretinoin exposure. His mother also had a history of urine tract infection in the second week of pregnancy that was treated with cephalexin. The parents were not from a consanguineous marriage and had no family history of congenital malformations. To reduce the risk, effective contraception should be continued in fertile women more than 1 month after completing therapy.

AIM: Zinc sulfate is beneficial in the treatment of epithelial warts. We conducted this study to compare the efficacy of combination therapy of oral zinc sulfate with conventional treatments in the treatment of vulvar warts. MATERIAL AND METHODS: This study was a randomized controlled trial. The sample size was 42 in each group. Women aged 20-50 years were placed by the block randomized method into six groups: the podophyllin-, imiquimod- and cryotherapy-treated groups, and another three groups receiving 8-week combination therapy of 400 mg oral zinc sulfate with one of the above-mentioned treatments. Data were analyzed using anova and Fischer's exact test with spss16. RESULTS: A total of 228 patients were recruited and completed the study in six treatment groups. No significant difference was observed in the response to treatment among these groups. Relapse after 6 months was significantly higher in the podophyllin-, imiquimod- and cryotherapy-treated patients compared to patients receiving these treatments in combination with oral zinc sulfate (P<0.05). CONCLUSIONS: Combined therapy of oral zinc sulfate with conventional treatments of vulvar warts appears to reduce the relapse rate.

Fetal hemolysis is caused by maternal antibodies that cross the placenta. Anti-M antibodies can rarely cause severe forms of alloimmunization in the fetus and newborn. We present a case of severe anti-M alloimmunization requiring a total of 8 intrauterine transfusions, in a patient with a prior poor obstetrical history. A 35-year-old Iranian pregnant woman with a prior obstetrical history of one abortion and two stillbirths was found to have had anti-M antibody titers 1:8 and accompanying elevated middle cerebral artery peak systolic velocity (MCA-PSV) of 1.9 MoM suggestive of severe fetal anemia at 17 weeks of gestation. Persistently elevated fetal MCA-PSV was noted despite intraperitoneal transfusion at 17, 19, and 22 weeks. Fetal blood sampling at 27 weeks confirmed severe fetal anemia (3 g/dL), which required additional intravascular and intraperitoneal blood transfusion. At 37 weeks, elective cesarean section was performed. Neonatal hemoglobin immediately after delivery was 10.1 g/dL. In addition to standard supportive care, the neonate required two additional transfusions and remained in the neonatal intensive care unit (NICU) for 23 days. Anti-M antibodies are a rare cause of severe alloimmunization. We present a case in order to improve management.
RESUMEN
Understanding the underlying causes of congenital anomalies (CAs) can be a complex diagnostic journey. We aimed to assess the efficiency of exome sequencing (ES) and chromosomal microarray analysis (CMA) in patients with CAs among a population with a high fraction of consanguineous marriage. Depending on the patient's symptoms and family history, karyotype/Quantitative Fluorescence- Polymerase Chain Reaction (QF-PCR) (n = 84), CMA (n = 81), ES (n = 79) or combined CMA and ES (n = 24) were performed on 168 probands (66 prenatal and 102 postnatal) with CAs. Twelve (14.28%) probands were diagnosed by karyotype/QF-PCR and seven (8.64%) others were diagnosed by CMA. ES findings were conclusive in 39 (49.36%) families, and 61.90% of them were novel variants. Also, 64.28% of these variants were identified in genes that follow recessive inheritance in CAs. The diagnostic rate (DR) of ES was significantly higher than that of CMA in children from consanguineous families (P = 0·0001). The highest DR by CMA was obtained in the non-consanguineous postnatal subgroup and by ES in the consanguineous prenatal subgroup. In a population that is highly consanguineous, our results suggest that ES may have a higher diagnostic yield than CMA and should be considered as the first-tier test in the evaluation of patients with congenital anomalies.
