Interleukins IL33/ST2 and IL1-β in Intrauterine Growth Restriction and Seropositivity of Anti- Antibodies.

() is the causal agent of toxoplasmosis. It may produce severe damage in immunocompromised individuals, as well as congenital infection and intrauterine growth restriction (IUGR). Previous reports have associated interleukin IL-33 with miscarriage, fetal damage, and premature delivery due to infections with various microorganisms.

Fetal Laryngoscopy and Endoscopic Tracheal Intubation to Avoid ex utero Intrapartum Treatment in the Management of Fetuses with Suspected Airway Obstruction.

Introduction: Large congenital neck tumors can cause neonatal death due to airway obstruction. The aim of this study was to report outcomes of the first cohort of fetuses with neck masses and suspected airway obstruction managed with fetal laryngoscopy (FL) and fetal endoscopic tracheal intubation (FETI) to secure fetal airways and avoid ex utero intrapartum treatment (EXIT) procedure.

Methods: A prospective observational cohort of consecutive fetuses with neck masses that were candidates for an EXIT procedure due to suspicion of laryngeal and/or tracheal occlusion on ultrasonographic (US) or magnetic resonance imaging (MRI) examination were recruited for FL in a tertiary referral center in Queretaro, Mexico.

Management of atypical cases of twin-to-twin transfusion syndrome.

Up to 20% of monochorionic diamniotic twin pregnancies can be complicated with twin-to-twin transfusion syndrome (TTTS). This complication is diagnosed by ultrasound demonstrating amniotic fluid discordance between both amniotic sacs, with polyhydramnios in the recipient's sac and oligohydramnios in the donor's, secondary to an imbalance in blood volume exchange between twins. Ultrasound evaluation of the amniotic fluid volume, bladder filling, and assessment of fetal Doppler parameters provide the basis for classification of TTTS, allowing severity assessment.

Unusual retrospective prenatal findings in a male newborn with Timothy syndrome type 1.

Timothy syndrome 1 (TS1) is a multisystem disorder characterized by severe QT prolongation and potentially lethal ventricular arrhythmias in the first years of life, plus other cardiac and extracardiac manifestations caused by mutation in the CACNA1C gene, a CaV1.2 L-type calcium channel. Here, we report retrospectively an unusual fetal presentation on a second patient with TS1 with fetal hydrops due to a congenital AV block and its postnatal diagnosis by a marked prolongation of the corrected QTc interval of 570 ms and a missense mutation, p.

[Prenatal diagnosis of fetal heterotaxy syndromes: report of two cases and review of the literature].

We describe the prenatal sonographic findings in two cases of fetal heterotaxy syndrome evaluated at the Maternal Fetal Medicine Unit of a tertiary hospital over a period of one year and present a review of the literature on the subject.

[Reference tables of fetal biometry for people in the West of Mexico].

Background: Fetal growth has geographical and ethnic variations. Fetuses from different parts of the world show also different growth patterns. Using individualized fetal biometry charts increase the detection of fetuses at risk, probably due to a better identification of intrauterine growth restriction; moreover they correlate better with anthropometric parameters than conventional curves.

[Modified Misgav-Labach at a tertiary hospital].

Background: According to several studies from around the globe, the modified Misgav Ladach technique simplifies the surgical procedure for cesarean section, reduces operation time, costs, and complications, and optimizes obstetric and perinatal outcomes.

Objective: Compare obstetric outcomes between patients operated on using traditional cesarean section technique and those operated on using modified Misgav Ladach technique.

Patients And Methods: The study included 49 patients operated on using traditional cesarean section technique and 47 patients operated on using modified Misgav Ladach technique to compare the outcomes in both surgical techniques.

[Anti-Ro/SSA antibodies in congenital heart block].

Describe a case of a female patient having anti-Ro/SSA antibodies without any other risk factor or collagen disease. In her first pregnancy a congenital heart block and hydrops in the fetus were diagnosed, and these caused stillbirth. In a second pregnancy an in utero treatment resulted in the succesful delivery of a normal child.

[IgM antiphospholipical antibodies in preeclampsia-eclampsia].

Background: Antiphospholipid antibodies are associated with thrombocytopenia and fetal loss, and have been reported elevated in patients with preeclampsia-eclampsia. Site: Preeclampsia-Eclampsia Research Unit, Instituto Materno Infantil del Estado de Mexico, Toluca, Mexico and the Specialty Hospital Research Unit, La Raza Medical Center, Mexico City, Mexico.

Objective: To determine the presence of anticardiolipin antibodies (IgG-IgM) as markers of acute endothelial damage in patients with preeclampsia.
