Use of a screening questionnaire for systemic lupus erythematosus among pregnant women in a Mexican population.

Objective: To conduct a diagnostic assessment of pregnant women using a screening questionnaire for SLE.

Materials And Methods: This was an analytical cross-sectional study carried out at the National Institute of Perinatology between 1 November 2019 and 28 February 2020, using a screening questionnaire for SLE. Antinuclear antibody and anti-double stranded DNA antibody tests and a clinical assessment by a rheumatologist were conducted for participants who obtained ≥4 positive responses on the questionnaire.

Transcervical chorionic villus sampling in a low-cost simulation model: Learning curve of maternal-fetal medicine fellows in Mexico.

The implementation of a low‐cost simulation model and cumulative sum analysis enables training and monitoring of individual learning curves for transcervical chorionic villus sampling.

Acute kidney injury in pregnancy and the role of underlying CKD: a point of view from México.

The incidence of acute kidney injury in pregnancy (P-AKI) in developed countries is significantly lower than in developing ones, where it is estimated to range between 4 and 26%. Mortality in cases of P-AKI requiring dialysis is high, varying from 20 to 80%. In developing countries, clinical decisions are often based on the availability of services and not on needs.

Controversies concerning the antiphospholipid syndrome in obstetrics.

Antiphospholipid antibody syndrome is a non-inflammatory autoimmune disease characterized by recurrent thrombotic events and/or obstetric complications associated with the presence of circulating antiphospholipid antibodies (anticardiolipin antibodies, anti-β glycoprotein-i antibodies, and/or lupus anticoagulant. Antiphospholipid antibodies are a heterogeneous group of autoantibodies associated with recurrent miscarriage, stillbirth, fetal growth restriction and premature birth. The diversity of the features of the proposed placental antiphospholipid antibodies fingerprint suggests that several disease processes may occur in the placentae of women with antiphospholipid antibody syndrome in the form of immune responses: inflammatory events, complement activation, angiogenic imbalance and, less commonly, thrombosis and infarction.

Amniotic band sequence: prenatal diagnosis, phenotype descriptions, and a proposal of a new classification based on morphologic findings.

Objective: The aim of this study is to describe the phenotype of fetuses affected by amniotic band sequence (ABS) that were diagnosed at the Instituto Nacional de Perinatología Isidro Espinosa de los Reyes and to propose a new classification based on morphologic findings.

Material And Methods: Cases with a final diagnosis of amniotic band sequence, diagnosed between January 1993 and July 2010 in the Department of Maternal Fetal Medicine, were reviewed. Demographic, clinical, and periconceptional data were collected, and the defects were described and classified.

Major craniofacial defects: case series and prenatal diagnosis at the Instituto Nacional de Perinatología, Mexico.

Objective: To describe the prenatal diagnosis, characteristics, development, perinatal outcome, and final diagnosis of pregnancies complicated by fetuses with major craniofacial defects, at the Instituto Nacional de Perinatologia, México, 1997-2008.

Material And Methods: A retrospective, descriptive study from January of 1997 to January 2008, analyzed 152 pregnancies complicated by fetuses with major craniofacial defects, diagnosed at the Department of Fetal Medicine of the National Institute of Perinatology. Data were obtained from patients clinical records.

[Diffuse cavernous hemangioma of the uterus diagnosed during pregnancy. Case report].

We report the case of a pregnancy of 16 weeks with anemia and a presumptive diagnosis of partial mole. In secondary care this diagnosis was ruled out through ultrasonography and diffuse cysts were found in the myometrium. Spectral Doppler ultrasound showed no flow, but it could be observed with power angiography.

[Fetal cardiopathy diagnostic approach at Instituto Nacional de Perinatologia].

Background: Congenital prenatal heart disease diagnosis is made by high definition ultrasound within 16 to 20 weeks of pregnancy, and each day more and more early.

Objective: To describe fetal heart disease cases, to evaluate its confirmation thorough post-natal diagnosis and perinatal result, and to establish a diagnose management algorithm.

Material And Method: Cases series of maternal-fetal medicine department at Instituto Nacional de Perinatología, from January 1996 to June 2006.

[Application of a technique to establish criteria for uterine length measurement].

Background: The uterine length measurement is a routine practice in the prenatal care of pregnant women. It has been attributed a sensibility of 86% to detect fetal grown restriction. The technique is easy to perform and reproducible between observers, although we have found variation between intra- and inter-observers measurements.

[Perinatal results of the patients assessed by fetal hypomotility].

Objective: To describe the perinatal outcome of those patients that come to emergency room because of diminished fetal movements.

Patients And Method: This is a case series in which we evaluated the patients who were attended at the Maternal Fetal Medicine Department from January 2002 to December 2003. All patients with prenatal control in the institution whatever the basic pathology were enrolled in the study.

[Thoracoamniotic shunts and thoracocentesis in fetal therapy].

Background: The not heart thoracic anomalies are caused by different abnormalities in the embryonic period with similar physiopathologic mechanisms. The prenatal treatment by means of decompression can improve substantially the clinical results in these patients.

Objective: To evaluate, in a qualitative way, the effect of the thoracoamniotic shunts and thoracocentesis in the perinatal outcome in fetuses with not heart thoracic anomalies.

[Doppler ultrasound to detect Rh: a systematic review].

Background: Red cell alloimmunization is an important cause of perinatal morbidlity and mortality. Invasive procedures used to diagnose fetal anemia are associated with serious fetal and maternal complications. The development of noninvasive techniques as Doppler ultrasound can help us in the fetal anemia diagnosis.

[Perinatal mortality: a proposed analysis].

Perinatal mortality is an epidemiologic indicator that evaluates materno-infantil quality care indirectly. Obtaining rates of perinatal mortality from continuous and confident information systems allow us a more precise evaluation of quality care in developed countries. In developing countries as Mexico, there aren't yet evaluating health programs that let us to know the actual situation of our medical care.
