Congenital deafness is a serious and irreversible condition in humans. The GJB2 gene is implicated in the pathogenesis of autosomal recessive nonsyndromic hearing loss. Its 235delC and 30-35delG polymorphisms are reported to be associated with risk of hereditary deafness. However, the effect of the interaction between GJB2 235delC and 30-35delG and environmental factors on congenital deafness has not been described. Therefore, we performed a case-control study to investigate the influence of these polymorphisms on congenital deafness risk, and their interaction with maternal and other environmental factors in the development of this disease...

INTRODUCTION: Otitis media (OM) is a common disease in childhood and hearing loss (HL) is the most common complication. Prolonged HL may lead to language delay and cognitive difficulties. However, the consequences of HL due to OM are not fully understood. The aim of this study was to determine the possible association between number of OM episodes in childhood and self-rated school performance controlling for potential confounders. METHODS: Prospectively gathered systematic interview data on OM episodes in early childhood and school performance at 11 years of age were obtained from The Danish National Birth Cohort, involving >100,000 individual pregnancies and their offspring...

BACKGROUND: Rubella infection can affect several organs and cause birth defects that are responsible for congenital rubella syndrome (CRS). Congenital hearing loss is the most common symptom of this syndrome, occurring in approximately 60% of CRS cases. Worldwide, over 100 000 babies are born with CRS every year. There is no specific treatment for rubella, but the disease is preventable by vaccination. Since 1969, the rubella vaccine has been implemented in many countries, but in Africa, only a few countries routinely immunize against rubella...

Duane's retraction syndrome (DRS) is characterized by limitations in horizontal eye movements, globe retraction, and palpebral fissure narrowing on attempted adduction. This disorder is caused by a disturbance in innervation originating in the brain stem and represents <1% of all cases of strabismus. It is postulated that this syndrome is due to an insult during the early weeks (8-10 weeks) of pregnancy and is 10-20 times more frequently associated with other systemic congenital anomalies. This case report of bilateral DRS included bilateral iris-retinal coloboma and congenital heart disease, sensory hearing loss, and inguinal hernia...

Intrauterine infections are a crucial pathogenic factor exerting an appreciable influence on the development of the fetus. They can provoke intrauterine death, cause multiple lesions in the organs and tissues as well as long-term complications that manifest themselves at the later stages of the growth and development of the child. One of such complications is the sensorineural loss of hearing. The importance of hearing impairment arises from the high prevalence of tis condition and frequent incapacitation it causes in the patients...

BACKGROUND: Recently, congenital cytomegalovirus (cCMV) infection was reported irrespective of a negative amniotic fluid prenatal analysis for cytomegalovirus (CMV). The question of whether this phenomenon represents low sensitivity of the test or late development of fetal infection (after amniocentesis) was discussed, but not answered. However, if late transmission is the rule, then infants born with cCMV after negative amniocentesis would be expected to carry better prognosis than those who tested positive...

INTRODUCTION: Puerperal psychosis (PP) is a psychiatric disorder that occurs in 1 out of 1000 pregnancies. Well known since antiquity, its symptoms have often been described in mothers, but few studies have successfully investigated a related disorder in fathers. The characteristic of this pathology is more related to its appearance than to its semiological description which is why its nosographic place is always discussed. The objective here is to focus on the definition of PP and to suggest an entity for both genders...

CONCLUSION: Sudden sensorineural hearing loss (SSNHL) in pregnancy is rare. It usually occurs in the third trimester. SSNHL in pregnancy does not increase risks during delivery or subsequent stroke. OBJECTIVES: This study aimed to investigate the incidence and to determine the factors associated with SSNHL in pregnancy. METHOD: Data were retrieved from Taiwan's National Health Insurance Database (NHIRD), covering the years 2000-2009. Patients admitted for SSNHL during pregnancy were enrolled...

The objective of the present work was to study the function of the retrocochlear auditory pathway in the premature infants with intrauterine growth retardation (IGR) in comparison to that of the normotrophics of a similar gestational age during the third and sixth months of life by recording auditory steady-state responses (ASSR). The audiological examination by the method of auditory steady-state response (ASSR) involved 127 children at the 3d month of life and in 97 children at the 6th month of life. It was shown that the ASSR thresholds at certain frequencies during the 3d and 6th months of life of the children born after the 32d week of pregnancy were significantly higher than in the children born after 32 weeks gestation...

Noise, a modern day curse of advancing infrastructure and technology, has emerged as an important public health problem. Exposure to noise during pregnancy may result in high-frequency hearing loss in newborns, growth retardation, cochlear damage, prematurity and birth defects. Newborns exposed to sound above 45 decibels may experience increase in blood pressure, heart rate, respiratory rate; decreased oxygen saturation; and increased caloric consumption. Noise exposure in older children may result in learning disabilities, attention difficulties, insulin resistance, hypertension, stress ulcers and cardiovascular diseases...

Cytomegalovirus (CMV) is the most common cause of congenital infection, and is a major cause of sensorineural hearing loss and neurological disabilities. Evaluating the risk for a CMV infected fetus to develop severe clinical symptoms after birth is crucial to provide appropriate guidance to pregnant women who might have to consider termination of pregnancy or experimental prenatal medical therapies. However, establishing the prognosis before birth remains a challenge. This evaluation is currently based upon fetal imaging and fetal biological parameters, but the positive and negative predictive values of these parameters are not optimal, leaving room for the development of new prognostic factors...

After first defining surrogacy, distinguishing between cases in which the pregnancy results from the surrogate's own egg or a donor egg, and examining the different configurations of male homosexual families, the authors outline French and foreign legislation and provide a summary of the literature and of French working group hearings. Arguments for and against lifting the ban on surrogacy for gay couples are examined. The main arguments for lifting the ban are the following: 1) the same-sex couple's desire to start a family from their own gene pool, 2) current obstacles to adoption, 3) the notion of equality between heterosexual and homosexual couples, 4) frequent recourse to surrogacy abroad, which is not only very costly but also leaves the child in a state of legal limbo on its return to France, and 5) the lack of access to therapeutic alternatives...

Newborn screening is a public health effort that has changed the prognosis of some congenital diseases. Newborn screening programmes differ between countries in which it is organized. Demographic, epidemiological or economic factors play a role in the choice of the screening panel. In the French Community of Belgium, the programme focuses on 13 metabolic and endocrine diseases, hearing loss and hemoglobinopathies (Brussels and Liege). Newborn screening is a complex process that requires the involvement of all stakeholders : parent information, blood sampling or testing, lab analysis, follow-up of the results, initiate adequate care in case of positive test and genetic counselling...

A couple with a proband child of GJB2 (encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis (PGD), noninvasive prenatal testing (NIPT), and noninvasive prenatal diagnosis (NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations...

It is estimated that 5.3% of newborns will suffer from a genetic disorder, when followed up until the age of 25 years. In developing, as compared to western countries, hemoglobinopathies and glucose-6-phosphate dehydrogenase deficiency have a higher incidence due to severe falciparum malaria in the distant past, and autosomal recessive disorders have a higher frequency due to greater proportion of consanguineous marriages. Chromosomal disorders have a combined frequency of 1 in 153 births, therefore screening for chromosomal disorders is essential, using biochemical markers, ultrasonography, and recently by non-invasive prenatal diagnosis based on cell-free fetal DNA in maternal plasma...
