RESUMEN

Endothelial dysfunction (ED) plays a prominent role in the pathogenesis of preeclampsia (PE). There is a need for non-invasive methods to assess endothelial function in preeclamptic patients. In the present study, adropin, autotaxin (ATX), and lysophosphatidic acid (LPA) were evaluated as indicators of ED. Patients diagnosed with PE and healthy pregnant women (n = 42 for each group) were compared. After measuring flow-mediated dilation (FMD), the participants were stratified as ED (+) or ED (-) based on a cut-off value of 6.5%. The PE patients were divided as early/late onset PE and severe/mild PE. Adropin, ATX, and LPA levels were measured, and their relevance to ED was evaluated. Student t, Mann-Whitney U, or ANOVA tests were used for statistics, as appropriate. Adropin levels were diminished in the ED (+) group, whereas ATX and LPA levels were increased. The decrease in adropin levels was more pronounced in severe PE, showing a positive correlation with the FMD. In the logistic regression model, adropin was the only parameter that was an independent variable for the FMD test (P < .001). Adropin measurements in serum may be of value for disease follow-up in patients with PE.

RESUMEN

OBJECTIVES: This study aims to assess the diagnostic accuracy of targeted ultrasound examination in prenatal diagnosis of hypospadias and to evaluate the predictive values of defined ultrasonographic findings of hypospadias. METHODS: The cases diagnosed with hypospadias in our fetal medicine center were identified on an electronic database. The ultrasound reports, images and hospital records were reviewed retrospectively. The predictive value of prenatal ultrasound diagnosis and the predictive values of each sonographic finding were assessed according to the postnatal clinical examinations. RESULTS: Thirty-nine cases were diagnosed with hypospadias on ultrasound during the 6 years. Nine fetuses with missing postnatal examination records were excluded. Twentytwo of the remaining fetuses had their prenatal diagnosis of hypospadias confirmed in postnatal examinations, indicating a 73.3 % positive predictive value. Normal external genitalia was detected in postnatal examinations of three fetuses. Five fetuses were diagnosed with other external genital abnormalities, including micropenis (n=2), clitoromegaly (n=2), and buried penis with bifid scrotum (n=1) in postnatal examinations. The positive predictive value of prenatal ultrasound for any external genital abnormality was 90 %. CONCLUSIONS: Although the positive predictive value of ultrasound for genital anomalies is satisfying, it is slightly lower for the specific diagnosis of hypospadias. This reflects overlapping ultrasound findings of different external genitalia anomalies. Standardized, systematic evaluation of the internal and external genital organs, karyotyping and genetic sex determination are essential to achieve a precise prenatal diagnosis of hypospadias.

RESUMEN

Thalassemia intermedia (TI) patients may need a transfusion during physiological stress conditions, such as pregnancy. We present a case of a female TI patient with emerging transfusion-refractory anaemia during pregnancy, which resolved after splenectomy performed simultaneously with cesarean delivery. A 26-year pregnant woman at 29th gestational weeks was referred with a diagnosis of TI due to emerging anaemia which was refractory to transfusion. Splenectomy at term was decided to improve anaemia, and transfusion response. A preterm infant was delivered by cesarean section due to threatened preterm labour. Once the uterine incision was closed, an open splenectomy was performed. Postoperative follow-up was uneventful. To the best of our knowledge, the present case is the first open splenectomy performed during cesarean delivery as a salvage option for the management of transfusion-refractory anaemia. Key Words: Thalassemia intermedia, Splenectomy, Pregnancy, Hemolytic anaemia.

RESUMEN

Intraoperative cell salvage (ICS) system performs autologous transfusion by filtering and reinfusing the shed blood into corporeal circulation during the surgery. Especially for pregnant Jehovah's Witnesses, the ICS system could be a life-saving intervention. This report describes the successful use of intravenous iron therapy and ICS during the cesarean delivery of a Jehovah's Witness diagnosed with placenta previa totalis who refused to receive any type of blood or blood product transfusion. Intravenous iron treatment initiated in the preoperative period can reduce the need for blood and blood product transfusion. The ICS system provides recognised advantages; however, its utilisation requires high technology equipment and skilled health staff. Key Words: Jehovah's witness, pregnancy, Iron therapy, Intraoperative cell salvage.

RESUMEN

Multiple congenital contractures (MCC) comprise a number of rare, non-progressive conditions displaying marked phenotypic and etiologic heterogeneity. A genetic cause can be established in approximately half of the affected individuals, attributed to genetic defects in the formation and functioning of the central and peripheral nervous system, neuromuscular junctions, skeletal muscles, and connective tissue. Ubiquitin-specific protease 14 (USP14) encodes a major proteasome-associated deubiquitinating enzyme with an established dual role as an inhibitor and an activator of proteolysis, maintaining protein homeostasis. Usp14-deficient mice show a phenotype similar to lethal human MCC phenotypes, with callosal anomalies, muscle wasting, and early lethality, attributed to neuromuscular junction defects due to decreased monomeric ubiquitin pool. We describe a new, autosomal recessive MCC phenotype in three fetuses from two different branches of a consanguineous family, presenting with distal arthrogryposis, underdevelopment of the corpus callosum, and dysmorphic facial features. Exome sequencing identified a biallelic 4-bp deletion (c.233_236delTTCC; p.Leu78Glnfs*11, SCV002028347) in USP14, and sequencing of family members showed segregation with the phenotype. RT-qPCR experiment in an unaffected heterozygote revealed that mutant USP14 was expressed, indicating that abnormal transcript escapes nonsense-mediated mRNA decay. We propose that herein described fetuses represent the first human phenotype of USP14 loss, with callosal anomalies and/or cortical malformations, multiple contractures, and recognizable dysmorphic facial features.

RESUMEN

Introduction: Infantile fibrosarcoma (IFS) usually arises in the extremities during the first 12 months of life and responds well to surgery. It is unusual in the oropharynx or the prenatal period. Case report: A giant solid mass was first detected in the oropharynx and anterior neck at 24 weeks of gestation by ultrasound and fetal MRI. An EXIT procedure with intrapartum intubation with appropriate supportive therapy was successful. The diagnosis of IFS was made postpartum, and the lesion responded to neoadjuvant chemotherapy. Conclusion: IFS may arise as early as 24 weeks of gestation. In this case, an EXIT procedure allowed postpartum diagnosis with subsequent treatment.

RESUMEN

Complete penoscrotal transposition is an extremely rare congenital anomaly and is usually associated with other urinary system abnormalities. Prenatal diagnosis is feasible by demonstrating perineal anatomy and its relation with scrotum and phallus. We describe two prenatal cases presenting with oligohydramniosis and megacystis due to lower urinary tract obstruction. Postnatal diagnosis was confirmed in both cases. Considering the dismal perinatal outcome, an accurate prenatal diagnosis is required for counseling the parents and preparing for postnatal care.

RESUMEN

RSV is one of the most important agents of lower respiratory infections in childhood. In this study, anti-RSV antibody levels in mother-infant pairs and factors related to antibody transfer ratio were investigated. One hundred and twenty-seven women that had term babies and their babies and 84 mother-infant pairs of them who continued the study after 6 months were enrolled. Anti-RSV IgG antibodies of the mothers and infants were positive in 46.5% and 61.5%, respectively. At the sixth month, anti-RSV antibodies were negative in all infants. Median of the anti-RSV antibody levels of the mothers and infants at birth were 12.08 IU/ml (1.21-119.27) and 13.78 IU/ml (3.99-108.6), respectively. There was a significant correlation between anti-RSV antibody levels of mothers and infants at birth (p: 0.0001, r: 0.667) and anti-RSV antibody levels of infants at birth and at 6th month (p: 0.0001, r: 0.343). Median ratio of infant and mother antibody levels was 1.22 (0.14-6.05). Median ratio that was detected in appropriate for gestational age infants was significantly higher than in small for gestational age or large for gestational age infants. In this study, the significant positive correlation between maternal antibody levels and infants' antibody levels at birth suggests that maternal vaccination strategies may be logical. We showed that antibody transfer rate was highest in appropriate for gestational age infants. It should be kept in mind that maternal vaccination strategies may be less effective in small for gestational age and large for gestational age infants.

RESUMEN

PURPOSE: To determine the true- and false-positive rates of cf-DNA testing in a cohort of patients from tertiary care centers and assess the impact of ultrasound examinations in pregnancy management. MATERIALS AND METHODS: Clinical, cytogenetic and ultrasound data of 101 consecutive fetuses were collected retrospectively. Cases were classified into five groups according to the ultrasound findings. Karyotyping, interphase FISH and microarray techniques were used for follow-up studies. RESULTS: The overall false-positive rate was low for trisomy 21 (T21, 8.2 %), but significantly higher for trisomy 18 (T18, 40 %), monosomy X (MX, 50 %), X/Y trisomies (57.1 %), trisomy 13 (T13, 71.4 %). While single cases of trisomy 16, trisomy 22 and 8q duplication positive in cf-DNA were confirmed, 3 microdeletions (1p36 and two 22q11.2) were not. About 75 % of confirmed T21's and all confirmed T18 and T13 had major markers and/or malformations. While false-negative cases (two T21, one T18 and one T13) were identified due to abnormal ultrasound findings, all false-positive cases were normal sonographically. Ultrasound findings of confirmed trisomy 16, 22, dup8q, monosomy X and other X/Y aneuploidies were unspecific. Term placenta studies were helpful to assess the role of confined mosaicism in unconfirmed cf-DNA test results. A vanishing twin has been observed as the likely cause of one false-positive T18. CONCLUSION: Our study contributes clinical data on discrepant cf-DNA testing results, corroborates the need for confirmational invasive testing and underscores the benefit of expert ultrasound in the prevention of fatal diagnostic errors.

RESUMEN

Persistent hyperplastic primary vitreous is a spectrum of congenital ocular abnormalities characterized by leukocoria, microphthalmia, cataracts, extensive intravitreal hemorrhage, persistence of the hyaloid artery, glaucoma, and retinal detachment. It might be isolated or associated with congenital syndromes such as trisomy 13, Walker-Warburg syndrome, and Norrie disease. We present 2 cases of persistent hyperplastic primary vitreous diagnosed by prenatal sonography in the early third trimester. Bilateral hyperechoic lenses and retinal nonattachment were detected in the sonographic examination of the first case, whereas irregular echogenic bands between the lenses and posterior walls of the eyes were prominent in the second case. In both of the cases, ocular findings were accompanied by intracranial findings, including severe hydrocephalus, an abnormal gyral pattern, and cerebellar hypoplasia, suggesting the diagnosis of Walker-Warburg syndrome. We also present a review of the literature regarding the prenatal diagnosis of this malformation.

RESUMEN

Tethered spinal cord is mostly caused by myelomeningocele and lipomyelomeningocele, while dermal sinus tract, diastematomyelia, lipoma, tumor, thickened/tight filum terminale, spinal trauma, and spinal surgery are among the other causes. Prenatal diagnosis of tethered cord has been reported, and it is usually associated with neural tube defects. We present an atypical presentation of a tethered spinal cord, which was associated with a sacrococcygeal teratoma and was diagnosed in the 23rd week of pregnancy by ultrasonography. © 2016 Wiley Periodicals, Inc.
