Risk factors associated with death in Brazilian children with severe dengue: a case-control study.

Objective: The purpose of this case-control study was to evaluate risk factors associated with death in children with severe dengue.

Methods: The clinical condition of hospitalized patients with severe dengue who died (cases, n = 18) was compared with that of hospitalized patients with severe dengue who survived (controls, n = 77). The inclusion criteria for this study were age under 13 years; hospital admission in São Luis, northeastern Brazil; and laboratory-confirmed diagnosis of dengue.

Prenatal diagnosis and postnatal findings of bronchogenic cyst.

Bronchogenic cysts arise from abnormal buds from the primitive esophagus and tracheobronchial tree, which do not extend to the site where alveolar differentiation occurs. Bronchogenic cysts are typically unilocular mucus field lesions arising from posterior membranous wall of the air way. The prenatal diagnosis usually is realized by two-dimensional ultrasound showing the large unilocular cystic image in the chest fetus.

Prenatal diagnosis of penoscrotal hypospadia in third trimester by two- and three-dimensional ultrasonography: a case report.

Hypospadia is an abnormal development of the corpus spongiosum, that involves cavernosa urethra, as a result of an inadequate fusion of the urethral folds. The incidence ranges from 0.2 to 4.

Prenatal diagnosis of intracranial immature teratoma in the third trimester using 2D and 3D sonography.

Intracranial tumors are uncommon and represent 0.5-1.5 % of all pediatric tumors.

Prenatal diagnosis and postnatal ultrasound findings of cloacal anomaly: a case report.

Cloacal malformation is an extremely rare fetal pathological condition that presents as a variety of defects. It predominantly affects females, with prevalence of 1 in 50,000 births. Prenatal ultrasonography on a 20-year-old caucasian woman (G4P1A2) at 33 weeks of pregnancy showed the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambiguous genitalia, and a single umbilical artery.

Prenatal diagnosis of Nager syndrome in the third trimester of pregnancy and anatomopathological correlation.

Nager syndrome or acrofacial dysostosis is a rare and complex malformation characterized by ear anomalies, micrognathia, radial limb hypoplasia, and absence of the thumb or other fingers. Since the original description of the syndrome in 1948, there have only been four reports of prenatal diagnoses in the literature, all during the second trimester, and only two of them had anatomopathological correlations. We describe a case of Nager syndrome that was suspected in the third trimester of gestation and confirmed postnatally through pathology.

Prenatal diagnosis of sacrococcygeal teratoma using two and three-dimensional ultrasonography.

Sacrococcygeal teratoma accounts for half of all fetal tumors, with a prevalence of 1 : 40,000 births. It is believed to originate from pluripotent cells in Hensen's nodule. Although most are benign, they are associated with high morbidity and mortality rates because the fetus develops congestive heart failure and hydrops.

Prenatal and Postnatal Schizencephaly Findings by 2D and 3D Ultrasound: Pictorial Essay.

Schizencephaly is a brain-destructive lesion relating to clefts in the fetal brain that usually communicate with the ventricular system, subarachnoid space, or both. It presents as two types: Type I (closed) and Type II (open). During pregnancy, it may be suspected in the course of ultrasonography, which highlights ventricular dilatation and brain abnormalities.

Prenatal diagnosis and postnatal findings of cephalothoracopagus janiceps disymmetros: a case report.

Conjoined twins are rare variants of monozygotic twins, which result from an incomplete division of the embryonic disk. Cephalothoracopagus is a rare twin pregnancy described as imperfect fusion of the head and chest, but separated columns, limbs, and pelvis. They occur with incidence rates that range from 1 per 50,000 to 1 per 100,000 births; however, the incidence of the cephalothoracopagus variety is 1 per 58 conjoined twins.

Prenatal diagnosis of an aneurysm of the vein of galen by three-dimensional power and color Doppler ultrasonography.

Aneurism of the vein of Galen is a complex arteriovenous malformation which is of multiply communications between of the vein of Galen and the cerebral arteries. It represents less than 1% of the cerebral arteriovenous malformations. Few cases using three-dimensional (3D) power and color Doppler ultrasound have been reported in the literature.

Predictive model for spontaneous preterm labor among pregnant women with contractions and intact amniotic membranes.

Purpose: To determine a predictive model for supporting decisions relating to the prognosis for women presenting with preterm labor and intact membranes.

Method: We conducted a prospective observational cohort study on 70 pregnant women at between 22 and 34 weeks of gestation. Transvaginal sonographic evaluation on the cervix was performed once on women who had completed a course of parenteral tocolysis.
