RESUMO

OBJECTIVE: To examine the potential role of the type of basal insulin on glycemic control and maternal and foetal outcomes in pregnant women with type 1 diabetes (T1DM). STUDY DESIGN: Retrospective cohort study of pregnancies attended at 18 Spanish tertiary hospitals. INCLUSION CRITERIA: T1DM, singleton pregnancies, delivery between 2002-2010, and use of the same basal and prandial insulin from before pregnancy until delivery. RESULTS: A total of 1534 pregnancies were included. The basal insulin most commonly used was Neutral Protamine Hagedorn (NPH) (51.7%), followed by glargine (23.2%) and continuous subcutaneous insulin infusion (CSII) (21.1%). CSII users had longer diabetes duration. Multiple logistic regression analysis showed that CSII was independently associated with lower doses of insulin, higher glycated haemoglobin (HbA1c) in all trimesters, and higher rates of miscarriage, preterm birth and neonatal hypoglycemia. Glargine was related to a higher risk of preterm birth and a small-for-gestational age infant (SGA). The odds ratios (OR) of the associations between insulin type and clinical outcomes (from 0.642 to 4.894) have a relevant magnitude. CONCLUSIONS: In this observational study of pregnant women with T1DM, the type of basal insulin was independently associated with metabolic variables and foetal outcomes.

RESUMO

OBJECTIVE: To assess the role of magnetic resonance imaging (MRI) in the prenatal diagnosis of neural tube defects (NTDs). BACKGROUND: NTDs comprise a heterogeneous group of congenital anomalies that derive from the failure of the neural tube to close. Advances in ultrasonography and MRI have considerably improved the diagnosis and treatment of NTDs both before and after birth. Ultrasonography is the first technique in the morphological study of the fetus, and it often makes it possible to detect or suspect NTDs. Fetal MRI is a complementary technique that makes it possible to clear up uncertain ultrasonographic findings and to detect associated anomalies that might go undetected at ultrasonography. The progressive incorporation of intrauterine treatments makes an accurate diagnosis of NTDs essential to ensure optimal perinatal management. The ability of fetal MRI to detect complex anomalies that affect different organs has been widely reported, and it can be undertaken whenever NTDs are suspected. CONCLUSION: We describe the normal appearance of fetal neural tube on MRI, and we discuss the most common anomalies involving the structures and the role of fetal MRI in their assessment. KEY POINTS: • To learn about the normal anatomy of the neural tube on MRI • To recognise the MR appearance of neural tube defects • To understand the value of MRI in assessing NTDs.

RESUMO

La ecografía ha sido el pilar único y fundamental del diagnóstico fetal dado que, hasta hace relativamente poco tiempo, no existía ninguna otra técnica no invasiva, válida y fiable que permitiera una correcta valoración morfológica prenatal. A pesar del gran avance tecnológico en ecografía obstétrica no todas las anomalías son visibles mediante esta técnica. Respecto al estudio morfológico de la cara, la ecografía no siempre permite valorarla correctamente, circunstancia manifiesta en la evaluación del paladar, debido a la osificación de las estructuras adyacentes y a la superposición de la lengua. La resonancia magnética fetal ha evolucionado considerablemente desde que se describió hace 25 años y se ha convertido en una herramienta incuestionable para la valoración fetal. Ha demostrado ser complementaria a la ecografía añadiendo información útil sobre la anatomía orofacial y permitiendo así una valoración precisa tanto del paladar primario, como del secundario (AU)


Sonography has been the fundamental pillar of fetal diagnosis, and until relatively recently, no other valid and reliable noninvasive technique that could adequately determine fetal morphology was available. However, even after the technological advances in obstetric sonography, is still unable to detect some anomalies. One example of this shortcoming is the morphological study of the face and neck. Owing to the ossification of adjacent structures and interposition of the tongue, sonography is not accurate in the detection of some of the most common anomalies. Enormous advances have been made in fetal magnet resonance imaging since it was first described 25 years ago. The usefulness of this modality as a tool to complement sonography in fetal evaluation is now firmly established. MRI provides useful information about orofacial anatomy, enabling accurate evaluation of both the primary and secondary palates (AU)

RESUMO

OBJECTIVE: To elucidate whether the risk of macrosomia, large for gestational age (LGA) and small for gestational age (SGA) is influenced by maternal body mass index and glucose tolerance differently in male and female fetuses. METHODS: A population study was conducted in 16 general hospitals from the Spanish National Health Service that included 9270 consecutive women with singleton pregnancies and without a former diagnosis of diabetes mellitus who delivered 4793 male and 4477 female newborns. Logistic regression analyses were performed to predict the effect of body mass index (BMI) category and glucose tolerance on macrosomia, large for gestational age newborns (LGA) and small for gestational age newborns (SGA) Separate analyses according to foetal sex were carried out for each outcome. The results were adjusted for maternal age, gestational age and pregnancy-induced hypertension. RESULTS: There were significant differences between males and females in the percentage of infants who had macrosomia, LGA or SGA. Maternal BMI category was positively associated with the risk of macrosomia and LGA in both male and female newborns. In addition, there was a negative association between maternal BMI and SGA that only reached significance in males. In contrast, gestational diabetes was only a predictor of macrosomia exclusively in male fetuses (OR 1.67, 95% CI 1.12 to 2.49) CONCLUSIONS: There is sexual dimorphism in the risk of abnormal birth weight attributed to maternal glucose tolerance status. A closer surveillance of foetal growth might be warranted in pregnant women with abnormal glucose tolerance carrying a male fetus.

RESUMO

AIMS/HYPOTHESIS: We evaluated diabetes-related pregnancy outcomes in a cohort of Spanish women in relation to their glucose tolerance status, prepregnancy BMI and other predictive variables. METHODS: The present paper is part of a prospective study to evaluate the impact of American Diabetes Association (2000) criteria in the Spanish population. A total of 9,270 pregnant women were studied and categorised as follows according to prepregnancy BMI quartiles and glucose tolerance status: (1) negative screenees; (2) false-positive screenees; (3) gestational diabetes mellitus (GDM) according to American Diabetes Association criteria only; and (4) GDM according to National Diabetes Data Group criteria (NDDG). We evaluated fetal macrosomia, Caesarean section and seven secondary outcomes as diabetes-related pregnancy outcomes. The population-attributable and population-prevented fractions of predictor variables were calculated after binary logistic regression analysis with multiple predictors. RESULTS: Both prepregnancy BMI and abnormal glucose tolerance categories were independent predictors of pregnancy outcomes. The upper quartile of BMI accounted for 23% of macrosomia, 9.4% of Caesarean section, 50% of pregnancy-induced hypertension and 17.6% of large-for-gestational-age newborns. In contrast, NDDG GDM accounted for 3.8% of macrosomia, 9.1% of pregnancy-induced hypertension and 3.4% of preterm births. CONCLUSIONS/INTERPRETATION: In terms of population impact, prepregnancy maternal BMI exhibits a much stronger influence than abnormal blood glucose tolerance on macrosomia, Caesarean section, pregnancy-induced hypertension and large-for-gestational-age newborns.

RESUMO

AIMS/HYPOTHESIS: This study was carried out to determine the impact of American Diabetes Association (ADA) 2000 criteria for the diagnosis of gestational diabetes mellitus (GDM) in the Spanish population. METHODS: Pregnant women were assigned to one of four categories: negative screenees, false-positive screenees, ADA-only-GDM (untreated) and GDM according to National Diabetes Data Group (NDDG) criteria (treated). Fetal macrosomia and Caesarean section were defined as primary outcomes, with seven additional secondary outcomes. RESULTS: Of 9,270 pregnant women screened for GDM, 819 (8.8%) met NDDG criteria. If the threshold for defining GDM had been lowered to ADA criteria, an additional 2.8% of women would have been defined as having the condition (relative increase of 31.8%). Maternal characteristics of women with ADA-only-GDM were between those of false-positive screenees and women with NDDG-GDM. The risk of diabetes-associated complications was slightly elevated in the individuals who would have been classified as abnormal only after the adoption of ADA criteria. In addition, the ADA-only-GDM contribution to morbidity was lower than that of other variables, especially BMI. CONCLUSIONS/INTERPRETATION: Use of the ADA criteria to identify GDM would result in a 31.8% increase in prevalence compared with NDDG criteria. However, as the contribution of these additionally diagnosed cases to adverse GDM outcomes is not substantial, a change in diagnostic criteria is not warranted in our setting.

RESUMO

Subacute granulomatous thyroiditis (SGT) and subacute lymphocytic thyroiditis (SLT) present a similar evolution during the first year, however, posteriorly, except on rare occasions, SGT maintains normofunction while SLT may present relapse with persistent goiter or permanent hypothyroidism requiring periodic follow up. The presence of spontaneous pain and very elevated VSG have been described accompanying SGT but not SLT histologically proven to be used for differentiating these entities. Two cases with clinical criteria and cytological diagnosis of SLT consulted for spontaneous thyroid pain are presented. VSG greater than 50 mm/1st hour was suggestive of SGT. The importance of cytology for the correct management of subacute thyroiditis is emphasized.
