BACKGROUND: Prenatal diagnosis in pregnancies at risk of single-gene disorders is currently performed using invasive methods such as chorionic villus sampling and amniocentesis. This is in contrast with screening for common aneuploidies, for which noninvasive methods with a single maternal blood sample have become standard clinical practice. METHODS: We developed a protocol for noninvasive prenatal diagnosis of inherited single-gene disorders using droplet digital PCR from circulating cell-free DNA (cfDNA) in maternal plasma...

A vaccine against congenital human cytomegalovirus (CMV) infection is a major public health priority. Congenital CMV causes substantial long-term morbidity in newborns, particularly sensorineural hearing loss (SNHL), and the public health impact of this infection on maternal and child health is under-recognized. Although progress toward development of a vaccine has been limited by an incomplete understanding of the correlates of protective immunity for the fetus, knowledge about some of the key components of the maternal immune response necessary for preventing trans-placental transmission is accumulating...

INTRODUCTION: Hearing loss is conceptualized as any impairment of the ability to hear and/or detect speech or environment sounds, regardless of cause, type, or degree. It may occur at different stages of life; during pregnancy or childbirth, in childhood, adulthood or old age. It should be noted that aging is the most common cause of sensorineural hearing loss followed by noise-induced hearing loss, and both are closely related to the formation of reactive oxygen species. Dietary antioxidant supplementation has been employed as a therapeutic strategy to prevent and/or delay the risks of major human diseases...

BACKGROUND: Congenital cytomegalovirus (cCMV) infection is an important cause of hearing loss and neurodevelopment delay. While data on vertical transmission and neonatal outcome after singleton pregnancy with cCMV are well established, only scarce reports have addressed cCMV in multiple birth pregnancies. Furthermore, no studies have yet compared the outcome after birth and long-term follow-up of children with cCMV born after a singleton versus multiple pregnancies. METHODS: Infant outcome after birth of symptomatic versus asymptomatic infection was compared for infants born with cCMV after multiple (study group) and singleton (control group) pregnancies in a 1:2 ratio...

The prevalence of bilateral sudden sensorineural hearing loss (SSNHL) is less than 5% and the etiology of most cases is unknown. Due to many structural and functional similarities between the kidney and inner ear, many conditions, diseases, and drugs have both renal and cochlear effects and toxicities. There are several reports of SSNHL in patients with CRF, uraemic patient, hemodialysis treatment, and ARF. Here, we report a rare manifestation of SSNHL following severe postpartum hemorrhage that has simultaneous renal failure and cochlear impairment...

Cleft palate only (CPO) is one of the most common congenital malformations worldwide. The etiopathogenesis of CPO is not completely understood. Environmental factors, such as smoking, alcohol consumption, intake of drugs during pregnancy, advanced paternal age, have been demonstrated to be a risk of CPO, but conflicting results have also been published. Insufficient intake of folic acid during the pregnancy has been suggested to increase the risk for CPO. The demonstrated risk for siblings and the higher risk for monozygotic twins suggest a genetic etiopathogenesis for CPO...

Congenital cytomegalovirus (CMV) infection is the leading cause for sensorineural hearing loss and mental retardation in children without genetic diseases worldwide. There is little evidence guiding therapeutic strategies during pregnancy when intrauterine fetal CMV infection is confirmed. We provide a systematic review of the use of ganciclovir (GCV) or VGCV during pregnancy discussing safety of its use for mother and fetus and describe two cases of intrauterine therapy of fetal CMV infection with valganciclovir (VGCV)...

PURPOSE: To assess the knowledge, practice and attitudes of maternity clinicians regarding congenital cytomegalovirus (CMV). It is the most common congenital infection, and well-recognized cause of neurodevelopmental disability and hearing loss. New consensus recommendations state all pregnant women and health-care providers should be educated about congenital CMV infection and preventive measures. MATERIALS AND METHODS: An email questionnaire was distributed in October 2015 to specialists, diplomates (general practitioners), and trainees of the Royal Australian New Zealand College of Obstetricians and Gynaecologists (RANZCOG), and Victorian and New South Wales midwives...

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...

M Yu Boboshko, S M Vikhnina, I V Savenko
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...

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...
