Herlyn-Werner-Wunderlich (HWW) syndrome is a rare variant of Müllerian duct anomalies consisting of uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. Patients with HWW syndrome are usually asymptomatic until menarche, when they present with acute lower abdominal pain. Here we report a case of a female newborn with right renal agenesis diagnosed during the pregnancy. The patient presented with a protruding mass over the vaginal introitus that was associated with an obstructed hemivagina and uterine didelphys.

Our results indicate that a higher serum leptin level has stronger association with mild-to-moderate persistent AS compared with AR. Hence, serum leptin may be a stronger predictor for childhood AS compared with AR. Among the asthmatic children, higher serum leptin levels also showed stronger associations with female gender and being overweight.

Intermediate-dose oral erythromycin is effective and safe for the treatment of feeding intolerance in VLBW infants. The incidences of PNAC and ≥ stage II NEC were significant lower in the erythromycin group.

Hydranencephaly is a rare and fatal central nervous system disorder where all or nearly all of the bilateral cerebral hemispheres are absent. The extensive hollow cerebrum is replaced with cerebrospinal fluid. Clinically, the differential diagnoses of hydranencephaly include severe hydrocephalus and alobar holoprosencephaly. Nearly all cases are sporadic, involving approximately 1 in 5000 continuing pregnancies. The exact main cause is still unknown, but hydranencephaly is usually found to develop secondarily to the occlusion of cerebral arteries above the supraclinoid level. We present the case of a 1-month-old male infant with hydranencephaly initially thought to be severely hydrocephalus via routine antenatal intrauterine sonography performed at 35 weeks of gestation. Hydranencephaly was confirmed by brain sonography, brain magnetic resonance imaging and magnetic resonance angiography postnatally. We discuss several imaging features that are helpful in distinguishing hydranencephaly from extreme hydrocephaly. Different theories that have been recently proposed regarding the origin of hydranencephaly are reviewed.

Mutations in the MID1 gene result in X-linked Opitz G/BBB syndrome (OS), a disorder that affects development of midline structures and comprises hypertelorism, cleft lip/palate, hypospadias, and laryngo-tracheo-esophageal abnormalities, and, at times, neurological, anal, and cardiac defects. MID1 gene abnormalities include missense, nonsense, and splicing mutations, small insertions, small deletions, and complex rearrangements. Here, we present a patient with Opitz G/BBB syndrome and a unique MID1 gene point mutation c.1703T

We report on a newborn girl with facial anomalies, a congenital heart defect, severe pre- and postnatal growth retardation, feeding problems, and persistent hyperplastic primary vitreous. Cytogenetic analysis by high resolution GTG banding showed extra chromosomal material on the short arm of one chromosome 1 of the patient, but neither parent. SKY and CGH analysis demonstrated that the patient had a de novo 46,XX, der(1)t(1;6)(p36.3; p22). Compared with previously reported cases of partial trisomy 6p22 syndrome, this patient exhibited a unique condition for this syndrome: persistent hyperplastic primary vitreous (PHPV) with retinal detachment. The human genome database was searched for candidate genes and we propose the following nine genes located in the 6p22→6pter region for their potential contribution to the phenotype of partial trisomy 6p22→pter and persistent hyperplastic primary vitreous (PHPV) with retinal detachment: Forkhead box Q1 (FOXQ1), FOXF2, FOXC1, NRN1, EDN1, ATXN1, DEK oncogene, E2F3, and NRNS1.

The pentalogy of Cantrell was first described in 1958 by Cantrell and coworkers, who reported five cases in which they described a pentad of findings including a midline supraumbilical thoracoabdominal wall defect, a defect of the Lower sternum, abnormalities of the diaphragmatic pericardium and the anterior diaphragm, and congenital cardiac anomalies. Trisomy 18 has an incidence of about 0.3 per 1000 newborns. We present a case of trisomy 18 with incomplete Cantrell syndrome. The patient presented with hypogenesis of the corpus callosum, vermian-cerebellar hypoplasia (Dandy-Walker variant), ventricular septal defect, dextrocardia, patent ductus arteriosus, a defect of the lower sternum, a midline supraumbilical abdominal wall defect with omphalocele, congenital left posterior diaphragmatic hernia (Bochdalek hernia), micrognathia, low-set and malformed ears, rocker-bottom feet, dorsiflexed hallux, hypoplastic nails, short neck, and wrist deformity. Trisomy 18 syndrome was unusually combined with the pentalogy of Cantrell. We present this case because of its rarity and high risk of mortality.
