Rubella is a contagious viral disease with few complications except when contracted by pregnant women. Rubella infection in pregnancy can result in miscarriage, stillbirth or an infant born with congenital rubella syndrome (CRS) which comprises deafness, heart disease, cataracts and other permanent congenital manifestations. Clinical diagnosis of rubella is difficult due to overlapping symptoms with many other diseases and confirmation of rubella is not possible without laboratory testing. Effective vaccination programmes are critical to the elimination of rubella and prevention of CRS. Such programmes have been successful in several countries in Europe and around the world. However, rubella outbreaks still occur due to suboptimal vaccine coverage and in the past 10 years rubella has been reported in Central European countries such as Romania and Poland. Over the past decade the elimination of rubella and prevention of congenital rubella infection in Europe has been a high priority for the WHO European Regional Office. In 2010 the WHO regional committee for Europe renewed its commitment to the elimination of rubella and prevention of CRS with a new target of 2015. This paper examines the current situation for rubella and CRS in Central Europe and describes the different rubella vaccination programmes in the region. The Central European Vaccination Advisory Group (CEVAG) recommends that two doses of measles, mumps and rubella vaccine, MMR, should be given to all children. The first dose should be given between 12 and 15 months of age. The second dose can be given between the ages of 21 months and 13 years with the exact age of administration of the second dose depending on the situation specific to each country. All suspected rubella cases should be laboratory-confirmed and monitoring systems to detect and investigate cases of CRS should be strengthened.

Choanal atresia is a rare otorhinolaryngological pathology. It occurs in 1 out of 5,000 children born alive and can be associated with other major or minor congenital abnormalities. The most important associations go under the acronym of C.H.A.R.G.E. (Coloboma, Heart disease, Atresia choanae, Retarded growth and/or development, Genital hypoplasia and Ear anomalies and/or deafness). The authors briefly describe the most salient clinical features and possible, though rare, complications of this anomaly (i.e., prolonged apnea, ab ingestis pneumonia, sinusitis, all the way to death by asphyxia). They also mention the current embryogenic theories advanced to explain the etiology. Foremost of these is the theory based on the persistence or inadequate development of the Hochstetter bucconasal membrane which is normally resorbed between the 35th and the 42nd day of intrauterine life, giving rise to the posterior nostril and primitive choana. The authors then present their personal experience with seven clinical cases of monolateral atresia in children ranging in age from 7 to 13 years, plus one case of bilateral atresia treated surgically 8 days after birth. They describe their surgical technique using intranasal and transseptal microsurgery. The patient undergoes general anesthesia in controlled hypotension. A surgical microscope with a 200-300 mm lens is used as well as the normal instrumentation for endonasal surgery. Access to the atresia lamina is gained through the floor of the nose and the lamina is perforated with a micro-osteotome. The excess bone tissue is removed and the neo-choana is calibrated and lined with the two mucosal flaps previously prepared. Then a silicone tube is positioned and anchored to the septum with a suture and left in place for approximately three weeks. Finally the authors indicate the most salient points of the other surgical techniques currently in use and they discuss their post-surgical treatment to prevent restenosis, comparing it with the experience of other authors.

CHARGE syndrome is a condition that has historically been diagnosed on the basis of the clinical findings of coloboma, heart disease, choanal atresia, restricted growth, and/or central nervous system anomalies, genital hypoplasia, and ear anomalies and/or deafness. Recently, researchers have discovered a genetic link, specifically, a strong association between the CHARGE phenotype and a mutation of the CHD 7 gene on the long arm of chromosome 8. Diagnosis now can be confirmed but not excluded with a positive mutation of this gene. This article offers an explanation of the diagnostic process as well as a description of the physical assessment and corresponding clinical implications of CHARGE syndrome in the neonatal population.

This is a report of a 6 month-old boy with a partial trisomy 2p24-->pter and monosomy 18q22-->qter. This is the first case presenting this unbalanced translocation with phenotypic features. The patient had growth and developmental retardation, facial dysmorphism, cleft palate, congenital cardiopathy, hypospadias, evantration of diaphragm and deafness. Cranial MRI showed mild ventricular dilatation. Cytogenetic analysis of the patient and his parents revealed a karyotype 46,XY, der(18), t(2;18)(p24;q22)mat in the patient. Subtelomeric FISH analysis confirmed the cytogenetic findings. Phenotypic features were consistent with either partial trisomy 2p or deletion 18q.

Mowat-Wilson syndrome is a genetic disease caused by heterozygous mutations or deletions of the zinc finger E-box-binding homeobox 2 (ZEB2) gene. The syndrome is characterized by typical facial features, moderate-to-severe mental retardation, epilepsy and variable congenital malformations, including Hirschsprung disease, genital anomalies, congenital heart disease, agenesis of the corpus callosum, and eye defects. The prevalence of Mowat-Wilson syndrome is currently unknown, but it seems that Mowat-Wilson syndrome is underdiagnosed, particularly in patients without Hirschsprung disease. We report here the first Egyptian case of Mowat-Wilson syndrome who was conceived by intracytoplasmic sperm injection. The patient manifested bilateral sensorineural hearing loss--a new feature not previously reported in cases of Mowat-Wilson syndrome. This report describes the first Egyptian patient of Mowat-Wilson syndrome who was conceived after intracytoplasmic sperm injection, and provides a new evidence for the inclusion of deafness among the congenital defects of the syndrome.

In mice and humans, loss of myosin VI (Myo6) function results in deafness, and certain Myo6 mutations also result in cardiomyopathies in humans. The current studies have utilized the Snell's waltzer (sv) mouse (a functional null mutation for Myo6) to determine if this mouse also exhibits cardiac defects and thus used to determine the cellular and molecular basis for Myo6-associated heart disease. Myo6 is expressed in mouse heart where it is predominantly expressed in vascular endothelial cells (VECs) based on co-localization with the VEC cell marker CD31. Sv/sv heart mass is significantly greater than that of sv/+ littermates, a result of left ventricle hypertrophy. The left ventricle of the sv/sv exhibits extensive fibrosis, both interstitial and perivascular, based on histologic staining, and immunolocalization of several markers for fibrosis including fibronectin, collagen IV, and the fibroblast marker vimentin. Myo6 is also expressed in lung VECs but not in VECs of intestine, kidney, or liver. Sv/sv lungs exhibit increased periaveolar fibrosis and enlarged air sacs. Electron microscopy of sv/sv cardiac and lung VECs revealed abnormal ultrastructure, including luminal protrusions and increased numbers of cytoplasmic vesicles. Previous studies have shown that loss of function of either Myo6 or its adaptor binding partner synectin/GIPC results in impaired arterial development due to defects in VEGF signaling. However, examination of synectin/GIPC-/- heart revealed no fibrosis or significantly altered VEC ultrastructure, suggesting that the cardiac and lung defects observed in the sv/sv mouse are not due to Myo6 function in arterial development.

To analyze congenital sensorineural hearing loss combined with blepharophimosis-ptosis-epicanthus inversus syndrome (BPES). For the case of cochlear implantation to child with congenital sensorineural deafness combined BPES, accomplish routine examination and assessment, combining with literature to analyze the clinical diagnosis of this disease and its significance. Sensorineural hearing loss is a common congenital diseases with neonatal incidence of 1 per thousand - 3 per thousand, 50%-70% of deafness is associated with genetic factors, the incidence of congenital sensorineural hearing loss combined with eye disease is about 40%-60%, mainly reflected in ametropia and retinopathy. BPES's main clinical manifestations is blepharophimosis, ptosis, epicanthus inversus, and telecanthus. BPES is a rare autosomal dominant disease caused by FOXL 2 gene mutation, sometimes associated with retarded growth, delayed development, congenital heart disease, and microcephaly. Suffering from both sensorineural hearing loss and BPES is rare in reported literature. This case is diagnosed by clinical examination, without visual impairment. Facial nerve dysplasia has been found during the surgery. For congenital deafness patients with eye disease or other diseases, timely and correct diagnosis has important clinical significance, which can improve the diagnostic rate and make it coming true to early intervention, and then, effectively improve the quality of the patients. There are few literature reports, of patients with two kinds of genetic diseases. Our inference is that the cases are rare or the patients has visited different departments and ignored the other systems' signs. Therefore, in such doubtful cases, we should do the professional comprehensive examination in daily clinical work in order to avoid missed diagnosis or delayed treatment and intervention. By analyzing this case, the patient may also suffer from facial nerve dysplasia. Preoperatively viewing CT scan and operatively facial nerve monitor being used can avoid the occurrence of surgical complications.

Persistent pulmonary hypertension of the newborn (PPHN) is characterized by elevated pulmonary vascular resistance resulting in right-to-left shunting of blood and hypoxemia. PPHN is often secondary to parenchymal lung disease (such as meconium aspiration syndrome, pneumonia or respiratory distress syndrome) or lung hypoplasia (with congenital diaphragmatic hernia or oligohydramnios) but can also be idiopathic. The diagnosis of PPHN is based on clinical evidence of labile hypoxemia often associated with differential cyanosis. The diagnosis is confirmed by the echocardiographic demonstration of - (a) right-to-left or bidirectional shunt at the ductus or foramen ovale and/or, (b) flattening or leftward deviation of the interventricular septum and/or, (c) tricuspid regurgitation, and finally (d) absence of structural heart disease. Management strategies include optimal oxygenation, avoiding respiratory and metabolic acidosis, blood pressure stabilization, sedation and pulmonary vasodilator therapy. Failure of these measures would lead to consideration of extracorporeal membrane oxygenation (ECMO); however decreased need for this rescue therapy has been documented with advances in medical management. While trends also note improved survival, long-term neurodevelopmental disabilities such as deafness and learning disabilities remain a concern in many infants with severe PPHN.

Objective: To explore the clinical phenotypes and the genetic cause for a boy with unexplained growth retardation, nephrocalcinosis, auditory anomalies and multi-organ/system developmental disorders. Method: Routine G-banding and chromosome microarray analysis were applied to a child with unexplained growth retardation, nephrocalcinosis, auditory anomalies and multi-organ/system developmental disorders treated in the Department of Pediatrics of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology in September 2015 and his parents to conduct the chromosomal karyotype analysis and the whole genome scanning. Deleted genes were searched in the Decipher and NCBI databases, and their relationships with the clinical phenotypes were analyzed. Result: A six-month-old boy was refered to us because of unexplained growth retardation and feeding intolerance.The affected child presented with abnormal manifestation such as special face, umbilical hernia, growth retardation, hypothyroidism, congenital heart disease, right ear sensorineural deafness, hypercalcemia and nephrocalcinosis. The child's karyotype was 46, XY, 16qh⁺ , and his parents' karyotypes were normal. Chromosome microarray analysis revealed a 1 436 kb deletion on the 7q11.23(72701098_74136633) region of the child. This region included 23 protein-coding genes, which were reported to be corresponding to Williams-Beuren syndrome and its certain clinical phenotypes. His parents' results of chromosome microarray analysis were normal. Conclusion: A boy with characteristic manifestation of Williams-Beuren syndrome and rare nephrocalcinosis was diagnosed using chromosome microarray analysis. The deletion on the 7q11.23 might be related to the clinical phenotypes of Williams-Beuren syndrome, yet further studies are needed.

Cardiac ion channelopathies are an important cause of sudden death in the young and include long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, idiopathic ventricular fibrillation, and short QT syndrome. Genes that encode ion channels have been implicated in all of these conditions, leading to the widespread implementation of genetic testing for suspected channelopathies. Over the past half-century, researchers have also identified systemic pathologies that extend beyond the arrhythmic phenotype in patients with ion channel gene mutations, including deafness, epilepsy, cardiomyopathy, periodic paralysis, and congenital heart disease. A coexisting phenotype, such as cardiomyopathy, can influence evaluation and management. However, prior to recent molecular advances, our understanding and recognition of these overlapping phenotypes were poor. This review highlights the systemic and structural heart manifestations of the cardiac ion channelopathies, including their phenotypic spectrum and molecular basis.
