    Over the past decade, amniotic fluid-derived stem cells have emerged as a novel, experimental approach for the treatment of a wide variety of congenital anomalies diagnosed either in utero or postnatally. There are a number of unique properties of amniotic fluid stem cells that have allowed it to become a major research focus. These include the relative ease of accessing amniotic fluid cells in a minimally invasive fashion by amniocentesis as well as the relatively rich population of progenitor cells obtained from a small aliquot of fluid. Mesenchymal stem cells, c-kit positive stem cells, as well as induced pluripotent stem cells have all been derived from human amniotic fluid in recent years. This article gives a pediatric surgeon’s perspective on amniotic fluid stem cell therapy for the management of congenital anomalies. The current status in the use of amniotic fluid-derived stem cells, particularly as they relate as substrates in tissue engineering-based applications, is described in various animal models. A roadmap for further study and eventual clinical application is also proposed. PMID:22986340

    Background Uterine malformation is a rare deformity in woman, and only a few cases concerning endometrial cancer arising in patients with congenital uterine anomalies have been reported. Herein, we present three cases of endometrial cancer with different congenital uterine anomalies, and review studies involving congenital uterine anomalies associated with endometrial cancer in the past 25 years, in order to identify similarities and differences in clinicopathologic characteristics and prognosis between endometrial cancer associated with uterine anomalies, and normal uterus.

    We describe a 1-year-old boy with congenital varicella syndrome who had vesicoureteral reflux (VUR) and neurogenic bladder. His mother had varicella during the 3rd month of pregnancy. At birth the patient presented with right microphthalmia, right microcornea, and persistent hyperplastic primary vitreous of the right eye. He had chronic constipation from 3 months of age. He had urinary tract infection at 1 year of age. Urological investigation revealed left grade V VUR and neurogenic bladder. His varicella zoster virus IgG titer measured by ELISA was 39.4 antibody index (normal <0.1). He had repeated episodes of urinary tract infection despite antibiotic prophylaxis and clean intermittent catheterization, and underwent a uretero-vesiconeostomy at 2 years of age. Maternal infection during early pregnancy and the serological evidence of varicella zoster IgG antibodies without a history of varicella after birth led to the diagnosis of congenital varicella syndrome. Urogenital anomalies have previously been described in 14 cases of congenital varicella syndrome. Most of these patients had neurogenic bladder, the pathophysiology of which could be explained by the known neurotropic nature of the virus.

    Congenital anomalies are an important cause of infant mortality and disability. Developmental exposure to environmental contaminants is thought to increase the risk for congenital anomalies. Herein, we describe a critical review of the literature conducted between February and March 2014 yielding 3057 references from which 97 unique relevant articles published from 2003 through 2014 were evaluated. Common congenital anomalies including hypospadias, cryptorchidism, anogenital distance (AGD), congenital heart defects and oral clefts were well represented in the literature whereas other outcomes such as neural tube defects, limb deficiency defects and gastroschisis were rarely described. While definitions used for congenital anomalies and methods of ascertainment were usually consistent across studies, inconsistencies were frequently found in grouping of different congenital heart defects. Despite strong links between some congenital anomalies and parental occupation, these studies are unable to provide clear insight into the specific chemicals responsible owing to lack of direct measures of exposure. In comparison, data are mixed for contaminant exposures at concentrations representative of results from contemporary biomonitoring studies. Of the environmental contaminants studied, the association between phthalate exposures and developmental abnormalities of the male reproductive tract received the greatest attention. Important limitations of the literature studied relate to adequacy of sample size, absence of or weaknesses in exposure assessment methodologies, failure to account for biological plausibility and grouping of congenital anomalies with divergent mechanisms. We conclude that the literature is inadequate at this time to support a conclusion that exposure to environmental contaminants are or are not associated with increased risks for congenital anomalies in the general population.

    Cardiac congenital abnormalities are a leading cause in neonatal mortality occurring in up to 1 in 200 of live births. Ebstein anomaly, also known as Kassamali anomaly, accounts for 1 percent of all congenital cardiac anomalies. This congenital abnormality involves malformation of the tricuspid valve and of the right ventricle. In this review, the causes of the anomaly are outlined and the pathophysiology is discussed, with a focus on the symptoms, management, and treatments available to date.

  6. Classifying sex biased congenital anomalies

    The reasons for sex biases in congenital anomalies that arise before structural or hormonal dimorphisms are established has long been unclear. A review of such disorders shows that patterning and tissue anomalies are female biased, and structural findings are more common in males. This suggests different gender dependent susceptibilities to developmental disturbances, with female vulnerabilities focused on early blastogenesis/determination, while males are more likely to involve later organogenesis/morphogenesis. A dual origin for some anomalies explains paradoxical reductions of sex biases with greater severity (i.e., multiple rather than single malformations), presumably as more severe events increase the involvement of an otherwise minor process with opposite biases to those of the primary mechanism. The cause for these sex differences is unknown, but early dimorphisms, such as differences in growth or presence of H-Y antigen, may be responsible. This model provides a useful rationale for understanding and classifying sex-biased congenital anomalies. 42 refs., 7 tabs.

    The French national neonatal screening program for congenital hypothyroidism (CH) was initiated in 1978. The purpose of this study was to ascertain the incidence of congenital extrathyroid anomalies (ETAs) among the infants with congenital hypothyroidism (CH) and to compare it with the Northeastern France Birth Defect Monitoring System data from 1979 to 1996. Among 129 CH infants on whom adequate data were available, 20 infants (15.5%) had associated congenital anomalies. Eight out of 76 infants with persistent CH had ETAs (10.5%) whereas 12 out of 53 children with transient hypothyroidism had ETAs (22.6%, p < 0.05). Some additional anomalies were considerably more common than in the general population. Nine infants had congenital cardiac anomalies (6.9%). This rises the question if teratogenic effects active during organogenesis may affect simultaneously many organs, including the developing thyroid, causing a relatively high percentage of CH infants with congenital ETAs.

    Understanding pancreatic development and the congenital anomalies and variants that result from alterations in normal development allows for better recognition of these anomalies at diagnostic imaging. This article reviews normal pancreatic embryology and anatomy, and the appearance of the more common developmental anomalies and ductal variants, with emphasis on computed tomography and magnetic resonance imaging. Common mimics of masses are also covered.

    Insulin analogues are commonly used in pregnant women with diabetes. It is not known if the use of insulin analogues in pregnancy is associated with any higher risk of congenital anomalies in the offspring compared with use of human insulin. We performed a literature search for studies of pregnant women with pregestational diabetes using insulin analogues in the first trimester and information on congenital anomalies. The studies were analysed to compare the congenital anomaly rate among foetuses of mothers using insulin analogues with foetuses of mothers using human insulin. Of 29 studies, we included 1286 foetuses of mothers using short-acting insulin analogues with 1089 references of mothers using human insulin and 768 foetuses of mothers using long-acting insulin analogues with 685 references of mothers using long-acting human insulin (Neutral Protamine Hagedorn). The congenital anomaly rate was 4.84% and 4.29% among the foetuses of mothers using lispro and aspart. For glargine and detemir, the congenital anomaly rate was 2.86% and 3.47%, respectively. No studies on the use of insulin glulisine and degludec in pregnancy were found. There was no statistically significant difference in the congenital anomaly rate among foetuses exposed to insulin analogues (lispro, aspart, glargine or detemir) compared with those exposed to human insulin or Neutral Protamine Hagedorn insulin. The total prevalence of congenital anomalies was not increased for foetuses exposed to insulin analogues. The small samples in the included studies provided insufficient statistical power to identify a moderate increased risk of specific congenital anomalies.

    Demonstration of a congenital renal anomaly plays an important role in the treatment of patients with renal infection. These patients are prone to infections because of coexisting urinary tract anomalies such as duplicated ureter, ureter opening anomalies, and urinary stasis. Assessment of renal parenchymal damage resulting from acute or chronic renal infection is the primary indication for radionuclide imaging with Tc-99m DMSA. In addition, this technique allows congenital anomalies to be identified. The authors review congenital renal fusion anomalies identified in children through Tc-99m DMSA imaging. They conclude that Tc-99m DMSA imaging can reveal important diagnostic information about various congenital anomalies, including fusion anomalies.

    The classification of posterior fossa congenital anomalies has been a controversial topic. Advances in genetics and imaging have allowed a better understanding of the embryologic development of these abnormalities. A new classification schema correlates the embryologic, morphologic, and genetic bases of these anomalies in order to better distinguish and describe them. Although they provide a better understanding of the clinical aspects and genetics of these disorders, it is crucial for the radiologist to be able to diagnose the congenital posterior fossa anomalies based on their morphology, since neuroimaging is usually the initial step when these disorders are suspected. We divide the most common posterior fossa congenital anomalies into two groups: 1) hindbrain malformations, including diseases with cerebellar or vermian agenesis, aplasia or hypoplasia and cystic posterior fossa anomalies; and 2) cranial vault malformations. In addition, we will review the embryologic development of the posterior fossa and, from the perspective of embryonic development, will describe the imaging appearance of congenital posterior fossa anomalies. Knowledge of the developmental bases of these malformations facilitates detection of the morphological changes identified on imaging, allowing accurate differentiation and diagnosis of congenital posterior fossa anomalies.

    Keratoglobus is a rare condition of bilateral corneal ectasia, which results in high myopia, irregular astigmatism, scarring, and rarely spontaneous globe rupture. Globoid protrusion of a clear, diffusely thin cornea is the pathology. The congenital form has been associated with blue sclera in which there is a systemic connective tissue disorder with abnormal collagen synthesis like Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta. Some concomitant abnormalities reported with kertoglobus include joint hypermobility, dental and skeletal abnormalities, osteal fragility, and deafness. Acquired forms have been reported to be associated with vernal keratoconjunctivitis and thyroid ophthalmopathy. We report the case of a 16-year-old boy with keratoglobus who presented with a history of photophobia and a low vision in both eyes since birth. He has been followed up by our pediatric cardiology department due to multiple cardiac anomalies. He had hypermobility of large joints, easy bruising, thin and hyperextensible skin with visible veins, which were also described in his elder brother. We aimed to discuss the etiology and the association of keratoglobus with some systemic abnormalities caused by collogen tissue disturbance, and make a brief review about the recent literature concerning the management of keratoglobus patients.

    MR imaging continues to be an integral problem-solving modality in the evaluation of congenital anomalies and acquired diseases of the female genital tract organs and provides effective clinical information to the practicing gynecologist in those patients in whom sonography is technically suboptimal or the results are equivocal. This article describes the state-of-the art MR imaging of the female pelvis and addresses its current perspectives in the following sections: (1) technical aspects of MR in imaging the female pelvis, (2) normal pelvic anatomy and variations that are seen on MRI, (3) role of MRI in the diagnosis of congenital uterine and vaginal anomalies, (4) MR imaging approach to diagnose congenital uterine and vaginal anomalies, (5) advantages and limitations of MR in the evaluation of various benign diseases and malignant neoplasms of the female genital tract, (6) a MR staging system and criteria for each gynecologic malignancy, (7) fundamental MR criteria to differentiate benign from malignant tumors and recurrent tumors from fibrosis, and (8) the present cost-effective value of MR in pregnancy and obstetrics. Magnetic resonance (MR) technology continues to be an important problem-solving modality in the evaluation of benign, malignant, and recurrent diseases of the female pelvic organs with the development of new software and improved hardware over the last few years. The main issues addressed in this article are (1) to review the basic and expanded applications of the current state-of-the art MR imaging in the diagnosis and management of various congenital and acquired disorders of the female pelvic organs, (2) to illustrate a simplified clinico-radiologic (MRI) approach to the diagnosis of congenital and acquired pathologies of the pelvic organs, (3) to provide relevant information to the clinicians to make rational choices among the competing imaging modalities, and (4) to outline the future potential of this modality in the pelvis.

    Objective To document the types of congenital renal anomalies detected in adulthood, the clinical presentation and complications of these renal anomalies, and the most useful imaging modality in detecting a renal anomaly. Materials and methods This study was approved by the institutional review board and informed consent was waived. Between January 2007 and January 2011, the clinical data and imaging studies of 28 patients older than 18 years diagnosed with renal anomaly at the authors’ institution were retrospectively reviewed. Renal anomalies in this study included only those with abnormality in position and in form. Results Of these 28 patients, 22 underwent imaging studies and their results constituted the material of this study. Of the 22 patients, 14 had horseshoe kidneys (HSK), four had crossed renal ectopia and four had malrotation. Sixteen patients were men and six were women. The patients ranged in age from 19 to 74 years (mean age 51.1 years). Clinical presentations were abdominal pain (13), fever (13), haematuria (4), palpable mass (2), asymptomatic (2), polyuria (1) dysuria (1), blurred vision (1), and headache with weakness of left extremities (1). Imaging studies included abdominal radiograph (15), intravenous pyelography (IVP) (8), retrograde pyelography (RP) (4), ultrasonography (US) (7), and computed tomography (CT) (9). Associated complications included urinary tract stones (17), urinary tract infection (16), hydronephrosis (12), and tumours (2). Abdominal radiograph suggested renal anomalies in nine out of 15 studies. IVP, RP, US and CT suggested anomalies in all patients who had these studies performed. However, CT was the best imaging modality to evaluate anatomy, function and complications of patients with renal anomalies. Conclusion HSK was the most common renal anomaly, with abdominal pain and fever being the most common presentations. UTI and stones were the most common complications. IVP, RP, US and CT can be used to diagnose renal

  16. Congenital anomalies surveillance in Canada.

    Lowry, R Brian

    2008-01-01

    Congenital anomalies (CA) are present in approximately 3% of all newborn babies and account for about 12% of paediatric hospital admissions. They represent an important public health problem. Surveillance is especially important so that preventive measures such as folic acid fortification can be properly assessed without resorting to a series of ad hoc studies. Canada's surveillance of CAs is weak, with only Alberta and British Columbia having established sytems. Most provinces have perinatal systems but their CA data are incomplete and they do not capture terminations of pregnancy. The same is true of the Public Health Agency of Canada's system. A new system, the Fetal Alert Network, has been proposed for Ontario, which represents a start but will require additional sources of ascertainment if it is to be a truly population-based system for Ontario.

    Ectopia cordis (EC) is a rare congenital anomaly associated with the heart positioned outside of the thoracic cavity either partially or completely. The ectopic heart can be found along a spectrum of anatomical locations, including the cervical, thoracic and abdominal regions and in most cases, it protrudes outside the chest through a split sternum. Although the first case of EC was identified during the early 1600s only 91 cases have been reported since then in the literature. This review will discuss the history and prevalence of EC, its etiology, morphology, presentation and symptoms, complications, diagnosis, treatment and management and prognosis.

  19. Minor congenital anomalies and ataxic cerebral palsy.

    PubMed Central

    Miller, G

    1989-01-01

    The incidence of minor congenital anomalies was examined in 36 patients with ataxic cerebral palsy, in unaffected family members, and in 100 unrelated control subjects. None of the control subjects or family members had more than four anomalies, and 25 of 36 (69%) of the patients had more than four. The distribution of anomalies differed considerably, with 60% of the index cases having seven or more, and 94% of the controls having three or less. The number occurring in the patients was significantly more than in their relatives. Of the 25 patients with more than four anomalies, 16 (64%) had undergone potentially adverse perinatal or early postnatal events. Thus minor congenital anomalies were considerably more frequent in those with ataxic cerebral palsy than in related or unrelated control subjects. These anomalies may be markers of early prenatal factors that contributed to the adverse outcome either directly or by predisposing to perinatal difficulties. PMID:2751330

    Cases with congenital heart defects (CHD) often have other associated anomalies. The purpose of this investigation was to assess the prevalence and the types of associated anomalies in CHD in a defined population. The anomalies associated with CHD were collected in all live births, stillbirths and terminations of pregnancy during 26 years in 346,831 consecutive pregnancies of known outcome in the area covered by our population based registry of congenital anomalies. Of the 4005 cases with CHD born during this period (total prevalence of 115.5 per 10,000), 1055 (26.3%) had associated major anomalies. There were 354 (8.8%) cases with chromosomal abnormalities including 218 trisomies 21, and 99 (2.5%) nonchromosomal recognized dysmorphic conditions. There were no predominant recognized dysmorphic conditions, but VACTERL association. However, other recognized dysmorphic conditions were registered including Noonan syndrome, fetal alcohol syndrome, and skeletal dysplasias. Six hundred and two (15.0%) of the cases had non syndromic, non chromosomal multiple congenital anomalies (MCA). Anomalies in the urinary tract, the musculoskeletal, the digestive, and the central nervous systems were the most common other anomalies. Prenatal diagnosis was obtained in 18.7% of the pregnancies. In conclusion the overall prevalence of associated anomalies, which was one in four infants, emphasizes the need for a thorough investigation of cases with CHD. A routine screening for other anomalies may be considered in infants and in fetuses with CHD. One should be aware that the anomalies associated with CHD can be classified into a recognizable anomaly, syndrome or pattern in one out of nine cases with CHD.

    2016-01-01

    Background: Congenital hand anomalies are numerous and markedly variant. Their significance is attributed to the frequent occurrence and their serious social, psychological and functional impacts on patient's life. Patients and Methods: This is a follow-up study of 64 patients with hand anomalies of variable severity. All patients were presented to Plastic Surgery Department of Sohag University Hospital in a period of 24 months. Results: This study revealed that failure of differentiation and duplication deformities were the most frequent, with polydactyly was the most common anomaly encountered. The mean age of presentation was 6 years and female to male ratio was 1.46:1. Hand anomalies were either isolated, associated with other anomalies or part of a syndrome. Conclusion: Incidence of congenital hand anomalies in Upper Egypt is difficult to be estimated due to social and cultural concepts, lack of education, poor registration and deficient medical survey. Management of hand anomalies should be individualised, carefully planned and started as early as possible to achieve the best outcome. PMID:27833283

    In this paper, we report a case of a 14-year-old girl with congenital aplasia of the flexor pollicis longus tendon who had no other associated anomalies of thumb hypoplasia and no trauma history. Flexor pollicis longus tendon anomalies are rare; several types of this congenital anomaly have been reported in the literature. The diagnosis should be considered if a patient is unable to flex the interphalangeal joint of the thumb. A hypoplastic thumb or an absent interphalangeal joint crease may be a diagnostic feature in such cases. Besides physical examination, we also used direct radiography and magnetic resonance imaging to diagnose this rare congenital anomaly in our patient.

    Congenital anomalies of the kidney and urinary tract anatomy (CAKUT) are common in children and represent approximately 30% of all prenatally diagnosed malformations. CAKUT is phenotypically variable and can affect the kidney(s) alone and/or the lower urinary tract. The spectrum includes more common anomalies such as vesicoureteral reflux and, rarely, more severe malformations such as bilateral renal agenesis. In young children, congenital anomalies are the leading cause of kidney failure and for kidney transplantation or dialysis. CAKUT can also lead to significant renal problems in adulthood and may present itself with hypertension and/or proteinuria. Congenital renal anomalies can be sporadic or familial, syndromic (also affecting nonrenal or non-urinary tract tissues), or nonsyndromic. Genetic causes have been identified for the syndromic forms and have shed some light into the molecular mechanisms of kidney development in human beings. The genetic causes for the more common nonsyndromic forms of CAKUT are unknown. The role of prenatal interventions and postnatal therapies as well as the benefits of screening affected individuals and their family members are not clear.

    Congenital optic nerve head anomalies are a group of structural malformations of the optic nerve head and surrounding tissues, which may cause congenital visual impairment and blindness. Each entity in this group of optic nerve anomalies has individually become more prevalent as our ability to differentiate between them has improved due to better characterization of cases. Access to better medical technology (e.g., neuroimaging and genetic analysis advances in recent years) has helped to expand our knowledge of these abnormalities. However, visual impairment may not be the only problem in these patients, some of these entities will be related to ophthalmologic, neurologic and systemic features that will help the physician to identify and predict possible outcomes in these patients, which sometimes may be life-threatening. Herein we present helpful hints, associations and management (when plausible) for them. PMID:25859137

  5. The impact of environmental pollution on congenital anomalies.

    PubMed

    Dolk, Helen; Vrijheid, Martine

    2003-01-01

    Major congenital anomalies are diagnosed in 2-4% of births. In this paper we review epidemiological studies that have specifically looked at congenital anomalies as a possible outcome of community exposure to chemical exposures associated with environmental pollution. These include studies of drinking water contaminants (heavy metals and nitrates, chlorinated and aromatic solvents, and chlorination by-products), residence near waste disposal sites and contaminated land, pesticide exposure in agricultural areas, air pollution and industrial pollution sources, food contamination, and disasters involving accidental, negligent or deliberate chemical releases of great magnitude. We conclude that there are relatively few environmental pollution exposures for which we can draw strong conclusions about the potential to cause congenital anomalies and, if so, the chemical constituents implicated, to provide an evidence base for public health and clinical practice. A precautionary approach should be adopted at both community and individual level. In order to prevent congenital anomalies, one must reduce exposure to potential teratogens before pregnancy is recognized (i.e. preconceptionally and in the first few weeks of pregnancy). It is a challenge to develop effective strategies for preconceptional care within the primary care framework. Prenatal service providers and counsellors need to be aware of the uncertainties regarding environmental pollution when addressing parental concerns.

    Congenital central nervous tumours form a unique group of neoplasms. They are different from other tumour groups not only due to the onset time but also to their histopathology, anatomic location, and biologic behaviour. Congenital glioblastoma is one of the rarest types of congenital brain tumours and is uncommon in the prenatal period. We report a rare case of congenital glioblastoma detected prenatally by ultrasound examination and magnetic resonance imaging at 26 gestational weeks. Based on MRI findings and consultation of a team of specialists, pregnancy was terminated at 28 weeks. The newborn presented hydrops foetal. The child died shortly after birth due to cardiorespiratory insufficiency. At autopsy a large tumour with a spongy-like appearance was found. The tumour involved nearly the whole right cerebral hemisphere and led to marked hydrocephalus. In the histological and immunohistochemical examination, the tumour presented features of glioblastoma. Neoplastic cells were immunopositive for GFAP, S-100 protein and negative for neuronal markers. Frequent mitoses and high MIB-1 labelling index were seen in the tumour areas. The coexistence of tumour and vascular developmental anomaly was stated. The conglomerates of numerous, distended, thin-walled foetal-like blood vessels were located beside the tumour tissue, which presented disturbance in differentiation and maturation of the vascular net. Such coexistence of malignant glioma with vascular developmental anomaly is unique.

    2014-01-01

    Background: There is a known association between congenital heart disease (CHD) and other congenital anomalies (CA). These associations have been altered by changes in prenatal factors in recent time. We reviewed the largest database of inpatient hospitalization information and analyzed the current association between common CHD diagnoses and other congenital anomalies. Materials and Methods: Case-control study design. We reviewed the Nationwide Inpatient Sample (NIS) database from 1998 to 2008 and identified all live births with CHD diagnosis (case) and live births without CHD diagnosis (control). We compared prevalence of associated congenital anomalies between the case and control groups. Results: Our cohort consisted of 97,154 and 12,078,482 subjects in the case and control groups, respectively. In the CHD population, prevalence of non-syndromic congenital anomaly (NSCA), genetic syndrome (GS), and overall extra-cardiac congenital anomaly (CA) were 11.4, 2.2, and 13.6%, respectively. In the control group, prevalence of NSCA, GS, and CA were 6.7, 0.3, and 7.0%, respectively. NSCA (odds ratio (OR): 1.88, confidence interval (CI): 1.73-1.94), GS (OR 2.52, CI 2.44-2.61), and overall CA (OR: 2.01, CI: 1.97-2.14) were strongly associated with CHD. Prevalence of GS and multiple organ-system CA decreased significantly over the study period. Conclusions: This is the largest and most comprehensive population-based study evaluating association between CHD and extra-cardiac malformation (ECM) in newborns.

    There are numerous congenital anomalies of the cervical spine. They can be simple and clinically inconsequential to complex with serious neurologic and structural implications. They can occur in isolation or as one of several maldeveloped organs in the patients. Many are discovered incidentally. The more common anomalies seen by pediatric spine surgeons include defects of the anterior or posterior arches of C1, occipital assimilation of the atlas, basilar invagination or impression, os odontoideum, and Klippel-Feil syndrome. Management begins with a detailed history, physical examination, and imaging studies. In general, those lesions that are causing or have caused neurologic injury, chronic pain, or spinal deformity or place the patient at high risk for developing these require treatment.

    Down syndrome (DS) is the most common congenital anomaly widely studied for at least 150 years. However, the type and the frequency of congenital anomalies associated with DS are still controversial. Despite prenatal diagnosis and elective termination of pregnancy for fetal anomalies, in Europe, from 2008 to 2012 the live birth prevalence of DS per 10,000 was 10. 2. The objectives of this study were to examine the major congenital anomalies occurring in infants and fetuses with Down syndrome. The material for this study came from 402,532 consecutive pregnancies of known outcome registered by our registry of congenital anomalies between 1979 and 2008. Four hundred sixty seven (64%) out of the 728 cases with DS registered had at least one major associated congenital anomaly. The most common associated anomalies were cardiac anomalies, 323 cases (44%), followed by digestive system anomalies, 42 cases (6%), musculoskeletal system anomalies, 35 cases (5%), urinary system anomalies, 28 cases (4%), respiratory system anomalies, 13 cases (2%), and other system anomalies, 26 cases (3.6%). Among the cases with DS with congenital heart defects, the most common cardiac anomaly was atrioventricular septal defect (30%) followed by atrial septum defect (25%), ventricular septal defect (22%), patent ductus arteriosus (5%), coarctation of aorta (5%), and tetralogy of Fallot (3%). Among the cases with DS with a digestive system anomaly recorded, duodenal atresia (67%), Hirschsprung disease (14%), and tracheo-esophageal atresia (10%) were the most common. Fourteen (2%) of the cases with DS had an obstructive anomaly of the renal pelvis, including hydronephrosis. The other most common anomalies associated with cases with DS were syndactyly, club foot, polydactyly, limb reduction, cataract, hydrocephaly, cleft palate, hypospadias and diaphragmatic hernia. Many studies to assess the anomalies associated with DS have reported various results. There is no agreement in the literature as to

    Ninety-four patients with congenital imperforate anus were studied to investigate: (1) the incidence of congenital spinal anomalies; (2) the orthopedic significance of these anomalies; (3) the incidence of other musculoskeletal disorders; and (4) the incidence of anomalies in other organ systems in the anal-spine anomaly group. There was a 38% incidence of spinal anomalies in 94 patients with congenital imperforate anus. Most of these abnormalities were sacral, and there were no related or progressive spinal deformities. The incidence of other musculoskeletal anomalies was much lower than of the spine (only 9% of the total). The triad of caudal regression-imperforate anus, spinal anomalies, and genitourinary tract anomalies-was present in 19 (53%) of the 36 cases, much more than any other combination of major system abnormalities such as the VATER of VACTEL syndromes.

  12. Congenital anomalies of the urinary tract.

    The upper urinary tract forms as a consequence of the reciprocal inductive signals between the metanephric mesenchyme and ureteric bud. A clue to the timing of events leading to an abnormality of the upper urinary tract can be the presence also of associated anomalies of internal genitalia since separation of these systems occurs at about the 10th week of gestation. Prenatal sonography has facilitated the detection of urological abnormalities presenting with hydronephrosis. Hydronephrosis suggests obstruction, but by itself cannot be equated with it. Instead, further radiographic imaging is required to delineate anatomy and function. Now, moreover, non-surgical management of CAKUT should be considered whenever possible. Despite the widespread use of prenatal screening sonography that usually identifies the majority of congenital anomalies of the urinary tract, many children still present with febrile urinary tract infection (UTI). Regardless of the etiology for the presentation, the goal of management is preservation of renal function through mitigation of the risk for recurrent UTI and/or obstruction. In the past many children underwent surgical repair aimed at normalization of the appearance of the urinary tract. Today, management has evolved such that in most cases surgical reconstruction is performed only after a period of observation - with or without urinary prophylaxis. The opinions presented in this section are not espoused by all pediatric urologists but represent instead the practice that has evolved at Children's National Medical Center (Washington DC) based significantly on information obtained by nuclear renography, in addition to sonography and contrast cystography.

    The aim of this study was to determine the incidence of associated urological and non-urological anomalies as well as the renal outcome in patients with a congenital solitary func-tioning kidney (CSFK). A retrospective review of 30 consecutive cases of CSFK seen at the pediatric renal service at the Jordan University Hospital between 2004 and 2008 was performed. There were 20 males and 10 females, whose ages ranged from five days to 14 years. In 20 patients (67%), the left kidney was absent. Associated anomalies were detected in 23 (77%) of the 30 patients; urological anomalies accounted for 47% (14/30) and non-urological anomalies were found in 19/30 (53%) patients. The latter included anomalies of the ear, nose and throat (ENT) in 9/30 (30%), musculoskeletal system (one with hypermobile joints) in 8/30 (27%), gastrointestinal (GI) in 7/30 (23%), cardiovascular (CV) in 4/30 (13%) and dermatological with epidermolysis bullosa, endocrine (euthyroid goiter) and gynecological (cervical cyst) in one patient each (3%). Proteinuria was seen in 6/30 (20%) and hypertension in 2/30 (7%) patients. Chronic renal failure (CRF) was seen in 6/30 (20%) patients, of whom three had end-stage renal failure (ESRF). CRF was seen mainly in patients with more than two associated urological anomalies. Idiopathic hyperuricosuria was found in five of the six tested patients (83%). In our study, the most common associated anomalies with CSFK were urological. The presence of more than two associated urological anomalies increased the risk of CRF.

    In recent years, clinics and radiology of congenital anomalies of the inferior vena cava have increased in importance in planning abdominal surgery, liver or kidney transplantation, or new interventional or diagnostic procedures such as the positioning of inferior vena cava filters to prevent pulmonary embolism, varicocel sclerotherapy and renal venous sampling. In the past, the radiologic assessment of these rare anomalies was performed only with angiography, which remains the most accurate diagnostic method. Today, besides angiography, less invasive examinations can be performed, e.g., US, CT and MRI, with MRA. In the last two years, 5 patients with inferior vena cava anomalies were examined: 3 had double inferior vena cava and 2 azygos continuation. All of them were submitted to US, CT, MRI and MRA and 3 patients underwent also angiography, two of them with double puncture. US can suggest the diagnosis but may be limited by technical factors and in the assessment of the whole inferior vena cava. Enhanced CT can depict anomaly extent, but uses contrast agents and ionizing radiations. Angiography better depicts craniocaudal spread and collateral networks but is an invasive procedure and sometimes needs a double puncture (double inferior vena cava). MRI, with MRA, yields the same information as the other modalities, but without contrast agents or ionizing radiations. The development of velocity encoded sequences will probably make this technique the method of choice in the study of inferior vena cava anomalies. Our study was aimed at reviewing the embryo-genesis of inferior vena cava anomalies and to assess the relative importance of different diagnostic procedures in the diagnosis and staging of these anomalies.

    Study Design Retrospective case study by clinical and radiological data analysis. Purpose To analyze different types of vertebral anomalies and the incidence of associated intraspinal anomalies in the Indian population. Overview of Literature This is the largest study of congenital scoliosis and associated intraspinal anomalies in Indian population. Incidence of intraspinal anomaly in this series is 47% which is higher than previous literature. Hemivertebra was the most common anomaly as seen in previous studies. Methods A total of 119 patients with congenital scoliosis who underwent surgery between December 2006 and December 2012 were studied. Data was reviewed with medical records, plain radiographs, and magnetic resonance imaging (MRI) scans. Results Thoracolumbar curve was most common, seen in 43.6% of patients. In addition to scoliotic deformity, kyphosis was seen in 26% of patients. Failure of formation, the most common vertebral anomaly, was seen in 51.2% of patients, failure of segmentation was seen in 19.3% of patients, and there were 29.4% patients having both formation and segmentation anomalies. Hemivertebra was the most common vertebral anomaly seen in 66.3% of patients and for whom 63.2% were in thoracic spine. Intraspinal anomalies were associated with 47% of patients with congenital scoliosis. Tethered cord was the most common intraspinal abnormality and was found in 48.2% patients with intraspinal anomalies. The patients with failure of segmentation and mixed deformities were found to have a significantly higher incidence of intraspinal anomalies (65% and 57%, respectively) than those with failure of formation (34%). Out of 31 patients with kyphotic deformity 29% had intraspinal anomalies, and amongst them tethered cord was the most common anomaly seen in 66% patients. Out of 12 patients with neurocutaneous markers, 83% patients had intraspinal anomaly. Conclusions Intraspinal anomalies were seen in 47% of patients with congenital scoliosis in the

    Congenital anomalies of the kidney and urinary tract (CAKUT) occur at a frequency of 1 in 500 live births and are a common cause of renal insufficiency in childhood. CAKUT encompass a wide spectrum of malformations including anomalies of the kidney, collecting system, bladder and urethra. Most cases of CAKUT are sporadic and limited to the urinary tract, but some of them are syndromic or associated with positive family history. To understand the basis of human renal anomalies, knowledge of kidney and urinary tract development is necessary. This process is very complicated, requires precise integration of a variety of progenitor cell populations of diverse embryonic origins and is controlled by many factors at every stage of development. This review focuses on the genetic factors leading to developmental errors of important morphogenetic processes, particularly in metanephric kidney induction and ureteric bud branching. The essential results of genetic studies in regard to CAKUT, performed on experimental models and in humans, are presented. However, further investigations are required to complete understanding of the complex molecular network, which will help us to determine novel preventive and therapeutic strategies for CAKUT.

    In 2011 and 2012, the Division of Microbiology and Infectious Diseases at the National Institute of Allergy and Infectious Diseases, National Institutes of Health, held a series of meetings to provide guidance to investigators regarding study design of clinical trials of vaccines and antimicrobial medications that enroll pregnant women. Assessment of congenital anomalies among infants born to women enrolled in these trials was recognized as a challenging issue, and a workgroup with expertise in epidemiology, pediatrics, genetics, dysmorphology, clinical trials, and infectious diseases was formed to address this issue. The workgroup considered 3 approaches for congenital anomalies assessment that have been developed for use in other studies: (1) maternal report combined with medical records review, (2) standardized photographic assessment and physical examination by a health professional who has received specific training in congenital anomalies, and (3) standardized physical examination by a trained dysmorphologist (combined with maternal interview and medical records review). The strengths and limitations of these approaches were discussed with regard to their use in clinical trials. None of the approaches was deemed appropriate for use in all clinical trials. Instead, the workgroup acknowledged that decisions regarding the optimal method of assessment of congenital anomalies will likely vary depending on the clinical trial, its setting, and the agent under study; in some cases, a combination of approaches may be appropriate. The workgroup recognized the need for more research on approaches to the assessment of congenital anomalies to better guide investigators in optimal design of clinical trials that enroll pregnant women.

    Congenital uterine anomaly is a female genital disorder caused by developmental anomaly of the Müllerian ducts. In this report, we present a case of repair of congenital 'disconnected uterus' between the cervix and the body of the uterus. The case did not correspond to the consensus classifications that have been proposed for congenital uterine anomaly. The patient was a young woman whose chief complaints were not having first menstruation and experiencing monthly severe lower abdominal pain. Magnetic resonance imaging showed that the uterine body was separated from the uterine cervix. Uteroplasty was conducted to anastomose the separated uterus. Periodic menstruation started 1 month after surgery and abdominal pain was improved. Performance of uteroplasty in this case was extremely significant and greatly improved the quality of life of the patient.

    Unfused crossed renal ectopia observed 1 in 75,000 autopsies is a rare congenital anomaly. Typically one kidney is located in the proximity of the other kidney, and the ureter of the anatomically anomalous kidney crosses the midline to insert to the bladder in its normal anatomic position. Although renal function is usually not affected, the condition is generally accompanied by other congenital anomalies. In this case report, static and dynamic scintigraphic images of two patients with unfused crossed renal ectopia are presented. Besides properties of imaging modalities, clinical features are discussed in light of the available literature.

    What is already known about this subject Cholesterol is known to be essential for fetal development. Statins, which inhibit cholesterol production, have therefore been considered as potential teratogens and are contraindicated in pregnancy. Data available thus far on the risks of congenital anomalies associated with statin therapy have come from non-analytic postmarketing surveillance studies. Given the increasing use of statins in women of childbearing age, there is a need for a population-based study on the risks of congenital anomalies associated with gestational statin use. What this study adds In this pharmacoepidemiological study, we determined the risk of congenital anomalies in women who filled prescriptions for statins during the first trimester of pregnancy, compared with women who had stopped statins before pregnancy or those who used fibrates during pregnancy. We found no evidence of an increased risk of fetal anomalies among first-trimester statin users, or any discernable pattern of congenital anomalies among live births. However, in the absence of outcome data on nonlive births, conclusions remain uncertain. Aims Evidence from animal studies suggests that statin medications should not be taken during pregnancy. Our aim was to examine the association between the use of statins in early pregnancy and the incidence of congenital anomalies. Methods A population-based pregnancy registry was built. Three study groups were assembled: women prescribed statins in the first trimester (group A), fibrate/nicotinic acid in the first trimester (group B) and statins between 1 year and 1 month before conception, but not during pregnancy (group C). Among live-born infants, we selected as cases infants with any congenital anomaly diagnosed in the first year of life. Controls were defined as infants with no congenital anomalies. The rate of congenital anomalies in the respective groups was calculated. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were

    Scan statistics have been used extensively to identify temporal clusters of health events. We describe the temporal cluster detection methodology adopted by the EUROCAT (European Surveillance of Congenital Anomalies) monitoring system. Since 2001, EUROCAT has implemented variable window width scan statistic for detecting unusual temporal aggregations of congenital anomaly cases. The scan windows are based on numbers of cases rather than being defined by time. The methodology is imbedded in the EUROCAT Central Database for annual application to centrally held registry data. The methodology was incrementally adapted to improve the utility and to address statistical issues. Simulation exercises were used to determine the power of the methodology to identify periods of raised risk (of 1-18 months). In order to operationalize the scan methodology, a number of adaptations were needed, including: estimating date of conception as unit of time; deciding the maximum length (in time) and recency of clusters of interest; reporting of multiple and overlapping significant clusters; replacing the Monte Carlo simulation with a lookup table to reduce computation time; and placing a threshold on underlying population change and estimating the false positive rate by simulation. Exploration of power found that raised risk periods lasting 1 month are unlikely to be detected except when the relative risk and case counts are high. The variable window width scan statistic is a useful tool for the surveillance of congenital anomalies. Numerous adaptations have improved the utility of the original methodology in the context of temporal cluster detection in congenital anomalies.

    This case-control study, conducted in a California county that had a local incident of water contamination in 1981, investigated the relation between a mother's reported consumption of tap water during pregnancy and congenital cardiac anomalies in their offspring born during 1981-1983. Data were obtained from telephone interviews with 145 mothers of children born with a severe cardiac anomaly and 176 mothers of children born without such an anomaly. A positive association between a mother's consumption of home tap water during the first trimester of pregnancy and cardiac anomalies in her infant was unrelated to the incident of water contamination, the mother's race, or her educational level. A negative relation was found between a mother's use of bottled water and cardiac anomalies among the infants. These findings corresponded primarily to births in 1981. These data could not fully distinguish between a potential causal agent in the water and differential reporting of exposure by study subjects.

    The European Surveillance of Congenital Anomalies (EUROCAT) network of population-based congenital anomaly registries is an important source of epidemiologic information on congenital anomalies in Europe covering live births, fetal deaths from 20 weeks gestation, and terminations of pregnancy for fetal anomaly. EUROCAT's policy is to strive for high-quality data, while ensuring consistency and transparency across all member registries. A set of 30 data quality indicators (DQIs) was developed to assess five key elements of data quality: completeness of case ascertainment, accuracy of diagnosis, completeness of information on EUROCAT variables, timeliness of data transmission, and availability of population denominator information. This article describes each of the individual DQIs and presents the output for each registry as well as the EUROCAT (unweighted) average, for 29 full member registries for 2004-2008. This information is also available on the EUROCAT website for previous years. The EUROCAT DQIs allow registries to evaluate their performance in relation to other registries and allows appropriate interpretations to be made of the data collected. The DQIs provide direction for improving data collection and ascertainment, and they allow annual assessment for monitoring continuous improvement. The DQI are constantly reviewed and refined to best document registry procedures and processes regarding data collection, to ensure appropriateness of DQI, and to ensure transparency so that the data collected can make a substantial and useful contribution to epidemiologic research on congenital anomalies.

    Sonographic detection and evaluation of congenital anomalies of the uterus represent an important segment in the additional therapeutic procedure, that is, treatment of patients with congenital anomalies of the uterus. Besides the primary reason that is manifested in the total cure of the patients, the secondary reason represents the decrease of costs of treatment of congenital anomalies of the uterus. Both descriptive and analytical methods were used in this paper. In 1997 Kurjak and Kupesic compared the sensitivity and specificity of transvaginal ultra sound, color Doppler, hysterosonography and three-dimensional ultrasound during diagnosis of the uterus septum. Representation of pathological findings in our paper in comparison to the examined group is: uterus subseptus = 15.38%, double horned uterus = 10.25%. The examined group includes intrauterine abnormalities of the uterus, analyzing, in that process, individual, pathological entities of intrauterine abnormalities. The research is a prospective, target, clinical study. In the examined group, due to the clinical suspicion of intrauterine abnormalities, 78 patients were examined in the following manner: two-dimensional transabdominal and transvaginal black-and-white and color Doppler ultrasound examinations were made and then three-dimensional transabdominal black-and-white and color Doppler ultrasound examinations. This means that in the detection of congenital anomalies of the uterus, the same sonographic techniques were first applied on the conventional and then also on the multidimensional base. Our research showed that three-dimensional technique is a more reliable diagnostic tool than two-dimensional technique. Sensitivity and specificity rate as well as positive predictive value show that this technique is an extraordinary one for assessing the volume, and position of congenital abnormalities.

    2016-08-01

    The purpose of this article is to review and summarize the etiopathogenesis, symptomatology, systemic associations, management, complications and clinical outcomes of congenital lacrimal fistulae. The authors performed an electronic database (PubMed, MEDLINE, EMBASE and Cochrane Library) search of all articles published in English on congenital lacrimal fistulae. Congenital subsets of patients from series of mixed lacrimal fistulae were included in the review. These articles were reviewed along with their relevant cross-references. Data reviewed included demographics, presentations, investigations, management, complications and outcomes. The prevalence of congenital lacrimal fistulae is reported to be around 1 in 2000 live births. They are frequently unilateral, although familial cases tend to be bilateral. Lacrimal and systemic anomalies have been associated with lacrimal fistulae. Exact etiopathogenesis is unknown but mostly believed to be an accessory out budding from the lacrimal drainage system during embryogenesis. Treatment is indicated when significant epiphora or discharge is present and is mostly achieved by various fistulectomy techniques with or without a dacryocystorhinostomy. Congenital lacrimal fistulae are a distinct clinical entity with unique features. Surgical management can be challenging and successful outcomes are usually achieved with widely accepted protocols.

    The surgical treatment of patients with extracardiac structural anomalies and congenital heart disease often carries major risk and remains a challenging field. An appropriate, solid treatment plan should be developed during the early phase with interactive intelligence sharing between a pediatric surgery team and congenital heart surgery team. As the top of the chain of command, the role of a neonatologist is important. This article reviews the history of surgery for congenital heart disease and the progress of the Japan Congenital Cardiovascular Surgery Database. Finally, as an example of a combination of diseases, the clinical course and intelligence sharing during treatment of a patient with biliary atresia requiring living-donor liver transplantation and hypoplastic left heart syndrome is reported. The National Quality Forum provided structural measures, process measures, and outcome measures for congenital heart surgery. Structural measures provided by the National Quality Forum included participation in a preoperative multidisciplinary conference. To improve the outcome of surgical treatment of patients with congenital heart disease and extracardiac structural anomalies, the importance of a preoperative multidisciplinary conference involving not only pediatric surgeons, pediatric cardiologists, and pediatric cardiac surgeons but also neonatologists, anesthesiologists, and nurses cannot be overemphasized.

    The presence of cancer and a congenital anomaly in the same child may be explained in certain cases by an underlying genetic abnormality. The study of these associations may lead to the identification of genes that are important in both processes. We have examined the records of 20,304 children with cancer in Britain, who were entered into the National Registry of Childhood Tumors (NRCT) during 1971-86, for the presence of congenital anomalies. The frequency of anomalies was much higher among children with solid tumors (4.4%) than among those with leukemia or lymphoma (2.6%; P < .0001). The types of cancer with the highest rates of anomalies were Wilms tumor (8.1%), Ewing sarcoma (5.8%), hepatoblastoma (6.4%), and gonadal and germ-cell tumors (6.4%). Cases of spina bifida and abnormalities of the eye, ribs, and spine were more common in children with cancer than among population-based controls. Future studies may be directed toward identifying the developmental pathways and the relevant genes that are involved in the overlap between pediatric cancer and malformation. PMID:9042906

    The presence of cancer and a congenital anomaly in the same child may be explained in certain cases by an underlying genetic abnormality. The study of these associations may lead to the identification of genes that are important in both processes. We have examined the records of 20,304 children with cancer in Britain, who were entered into the National Registry of Childhood Tumors (NRCT) during 1971-86, for the presence of congenital anomalies. The frequency of anomalies was much higher among children with solid tumors (4.4%) than among those with leukemia or lymphoma (2.6%; P < .0001). The types of cancer with the highest rates of anomalies were Wilms tumor (8.1 %), Ewing sarcoma (5.8%), hepatoblastoma (6.4%), and gonadal and germ-cell tumors (6.4%). Cases of spina bifida and abnormalities of the eye, ribs, and spine were more common in children with cancer than among population-based controls. Future studies may be directed toward identifying the developmental pathways and the relevant genes that are involved in the overlap between pediatric cancer and malformation. 46 refs., 12 tabs.

  13. The Neural Crest in Cardiac Congenital Anomalies

    This review discusses the function of neural crest as they relate to cardiovascular defects. The cardiac neural crest cells are a subpopulation of cranial neural crest discovered nearly 30 years ago by ablation of premigratory neural crest. The cardiac neural crest cells are necessary for normal cardiovascular development. We begin with a description of the crest cells in normal development, including their function in remodeling the pharyngeal arch arteries, outflow tract septation, valvulogenesis, and development of the cardiac conduction system. The cells are also responsible for modulating signaling in the caudal pharynx, including the second heart field. Many of the molecular pathways that are known to influence specification, migration, patterning and final targeting of the cardiac neural crest cells are reviewed. The cardiac neural crest cells play a critical role in the pathogenesis of various human cardiocraniofacial syndromes such as DiGeorge, Velocardiofacial, CHARGE, Fetal Alcohol, Alagille, LEOPARD, and Noonan syndromes, as well as Retinoic Acid Embryopathy. The loss of neural crest cells or their dysfunction may not always directly cause abnormal cardiovascular development, but are involved secondarily because crest cells represent a major component in the complex tissue interactions in the head, pharynx and outflow tract. Thus many of the human syndromes linking defects in the heart, face and brain can be better understood when considered within the context of a single cardiocraniofacial developmental module with the neural crest being a key cell type that interconnects the regions.

    Abstract Objective: To develop a classification system for congenital spine anomalies detected by prenatal ultrasound. Methods: Data were collected from fetuses with spine abnormalities diagnosed in our institution over a five‐year period between June 2005 and June 2010. The ultrasound images were analysed to determine which features were associated with different congenital spine anomalies. Findings of the prenatal ultrasound images were correlated with other prenatal imaging, post mortem findings, post mortem imaging, neonatal imaging, karyotype, and other genetic workup. Data from published case reports of prenatal diagnosis of rare congenital spine anomalies were analysed to provide a comprehensive work. Results: During the study period, eighteen cases of spine abnormalities were diagnosed in 7819 women. The mean gestational age at diagnosis was 18.8w ± 2.2 SD. While most cases represented open NTD, a spectrum of vertebral abnormalities were diagnosed prenatally. These included hemivertebrae, block vertebrae, cleft or butterfly vertebrae, sacral agenesis, and a lipomeningocele. The most sensitive features for diagnosis of a spine abnormality included flaring of the vertebral arch ossification centres, abnormal spine curvature, and short spine length. While reported findings at the time of diagnosis were often conservative, retrospective analysis revealed good correlation with radiographic imaging. 3D imaging was found to be a valuable tool in many settings. Conclusions: Analysis of the study findings showed prenatal ultrasound allowed detection of disruption to the normal appearances of the fetal spine. Using the three features of flaring of the vertebral arch ossification centres, abnormal spine curvature, and short spine length, an algorithm was devised to aid with the diagnosis of spine anomalies for those who perform and report prenatal ultrasound.

    Mutations in PIGN, resulting in multiple congenital anomalies-hypotonia-seizures syndrome, a glycosylphosphatidylinositol anchor deficiency, have been published in four families to date. We report four patients from three unrelated families with epilepsy and hypotonia in whom whole exome sequencing yielded compound heterozygous variants in PIGN. As with previous reports Patients 1 and 2 (full siblings) have severe global developmental delay, gastroesophageal reflux disease, and minor dysmorphic features, including high palate, bitemporal narrowing, depressed nasal bridge, and micrognathia; Patient 3 had early global developmental delay with later progressive spastic quadriparesis, intellectual disability, and intractable generalized epilepsy; Patient 4 had bilateral narrowing as well but differed by the presence of hypertelorism, markedly narrow palpebral fissures, and long philtrum, had small distal phalanges of fingers 2, 3, and 4, absent distal phalanx of finger 5 and similar toe anomalies, underdeveloped nails, unusual brain anomalies, and a more severe early clinical course. These patients expand the known clinical spectrum of the disease. The severity of the presentations in conjunction with the patients’ mutations suggest a genotype–phenotype correlation in which congenital anomalies are only seen in patients with biallelic loss-of-function. In addition, PIGN mutations appear to be panethnic and may be an underappreciated cause of epilepsy. PMID:26394714

    Objective The antenatal use of citalopram, a widely prescribed selective serotonin reuptake inhibitor, has been suspected to be associated with congenital, particularly cardiac, anomalies. This study aimed to prove the association between citalopram use and congenital anomalies. Methods We searched the English literature from July 1998 to July 2015, by using the search terms ‘ citalopram’, ‘ pregnancy’, ‘ birth defects’, ‘ congenital anomalies’, and ‘ malformations’ in PubMed, Embase, Web of Science, and the Cochrane Library. Results Eight eligible articles were analyzed including a total of 1,507,896 participants. The odds ratio (OR) of major malformations associated with citalopram use during pregnancy was 1.07 (95% confidence interval [CI], 0.98 to 1.17). Concerning cardiac malformations, the OR for all included studies was 1.31 (95% CI, 0.88 to 1.93). The analysis of cardiac malformations was repeated to reduce heterogeneity after excluding one outlier study (OR, 1.03; 95% CI, 0.84 to 1.26). Conclusion From our data, it can be concluded that citalopram use is not associated with major birth defects. However, physicians should carefully weigh the benefits against the potential risks of citalopram use, and counsel patients accordingly. PMID:28344955

    It is well known that congenital anomalies such as polycystic kidney, aortic coarctation, Marfan syndrome, Ehler-Danlos syndrome are apt to be complicated by intracranial aneurysms. In this report we attempt to reveal the relation and incidence between cerebrovascular anomalies and intracranial aneurysms. The etiology of aneurysms has been discussed, too. 12 cases of persistent trigeminl artery, 2 cases of persistent hypoglossal artery and 11 cases of fenestration were obtained from 3841 patients who were angiographically examined in our clinic for 5 years. The incidence is 0.31%, 0.05% and 0.29%, respectively. Persistent trigeminal arteries were complicated by 2 cases of intracranial aneurysms and one case of arterivenous malformations (AVM), persistent hypoglossal arteries were complicated by one case of aneurysm, and fenestrations were complicated by 2 cases of aneurysms and one case of AVM. One case of congenital agenesis of right internal carotid artery was obtained which was complicated by aneurysm of anterior communicating artery. Totally, 8 cases of aneurysms and AVM were obtained from 26 cases of cerebrovascular anomalies (incidence 30.8%). On the other hand, thalamic or caudate hemorrhage revealed the highest incidence of complication of intracranial aneurysms among intracerebral hematomas (10.7%). Compared with the incidence of aneurysms between cerebro vascular anomalies (30.8%) and thalamic or caudate hemorrhage (10.7%), the difference is statistically signigicant (P less than 0.05). The cause of intracranial aneurysm has not yet been clarified. But it is well accepted that the defect of tunica media vasorum is most responsible factor as to the occurrence of intracranial aneurysms. We concluded that the genetic error of cerebral vessels including defect of media caused intracranial aneurysms, and this result was supported from the evidence that cerebrovascular anomalies showed statistically high incidence of complication of intracranial aneurysms.

    As a preparatory step towards the development of a complete habilitation program for children with congenital limb anomalies associated with maternal ingestion of thalidomide, the medical records of all patients with congenital limb anomalies referred to the Rehabilitation Institute of Montreal in the past decade were studied, and an examination and a thorough reassessment were made of 41 patients (21 males and 20 females). The medical and prosthetic aspects were dealt with in Part I of this paper. Part II describes, in a joint report, the results of psychiatric, psychological and educational assessments.There was no evidence of major emotional disorder in any of the patients, although conflicts were intensified by the presence of the physical anomaly. No relation was found between intelligence, emotional adjustment and disability. The patient's attitude towards his disability and prosthesis is definitely influenced by the degree of parental acceptance of the handicap and by the character of the emotional undertones in the total environment. In order to favour the occurrence of the healthiest modes of development in these children, the authors believe that the medical profession should be made fully aware of the physical and emotional problems which may arise after the birth of a deformed child. It is considered very important that the mother should receive psychotherapeutic support as soon as possible after the child is born.

    Acute infection of toxoplasmosis during pregnancy is detrimental to the developing fetus. In the United States, approximately 1 in 10,000 live births are affected by congenital toxoplasmosis. Although multifactorial in etiology, maternal infection is primarily attributed to the consumption of contaminated meat or water. Infection and transmission to the fetus may result in devastating neurologic impairment. Screening methods for all pregnant women should be implemented in routine prenatal care. This article will highlight the inherent dangers of congenital toxoplasmosis, while including general care of the fetus for prevention of transmission, medical management, and long-term outcomes.

    Five feeding trials were performed on three ranches to determine if a distinctive, recurring, congenital anomaly in beef calves was associated with feeding clover or grass silage without supplementation to pregnant cows overwinter. The anomaly, termed congenital joint laxity and dwarfism, was characterized at birth by generalized joint laxity, disproportionate dwarfism, and occasionally, superior brachygnathia. The anomaly had been documented for several consecutive years on these ranches and affected 2-46% of the calf crop. Pregnant cows were divided randomly into feeding groups, and the number of abnormal calves in each group was tabulated. Supplementation of the overwinter grass/clover silage diet with hay (2.5-4.5 kg/head/day) and rolled barley (0.75-1.5 kg/head/day) eliminated the problem. Supplementation of grain, without hay, was not as effective. Varying the proportions of grass and clover in the silage, and the age of the silage, did not alter the teratogenic potency of silage. Vitamin D3 supplementation did not reduce the risk of the condition. The definitive cause of congenital joint laxity and dwarfism was not determined. ImagesFigure 1.Figure 2. PMID:17423291

    A 1-day-old, Toggenburg/Nubian crossbred goat of polled parentage was referred for necropsy because of a large (diameter, 5 cm) bladder-like mass protruding from the perineal midline and difficult urination. Differential diagnoses included cutaneous cyst, ectopic urinary bladder, and urethral diverticulum/dilatation. Several genitourinary aberrations were noted. A second, smaller (diameter, 1 cm), more distal cystic structure was adjacent to an ambiguous prepuce. Testicles were discovered within a constricted, subcutaneous space near the inguinal canals. A rudimentary penis was located dorsal to the penile urethra with no appreciable urethral process. A tiny external urethral orifice was discerned only after liquid was injected into the lumen of the cystic structures, confirming their identity as urethral dilatations. The dilatations were separated by a constricting band of fibrous tissue. No other significant findings were detected. This case illustrates a combination of congenital anomalies including bilateral cryptorchidism with scrotal absence, segmental urethral hypoplasia, and urethral dilatation, most likely associated with the intersex condition seen in polled breeds. The continued production and use of small ruminants as animal models demands the prompt recognition of congenital anomalies. This case also exemplifies the precautions required when breeding goats with polled ancestry.

    1979-01-01

    In a literature review of 108 articles a special effort was made to find and classify inner ear anomalies and diseases associated with inner ear anomalies. This study showed the following. Most of the diseases associated with inner ear anomalies are also associated with anomalies in other parts of the body. Hereditary characteristics comprise the most common etiological factor among the diseases associated with inner ear anomalies. Among anomalies observed in the cochlea, the vestibule, and the semicircular canals, anomalies in the cochlea are most frequently associated with various diseases and were observed in 30 of 40 diseases. Anomalies of the vestibule were observed in 25 diseases, and those of the semicircular canals in 18 diseases. Anomalies in both the osseous and the membranous labyrinth were most frequently associated with the diseases studied, as they were observed to occur with 10 of the 43 diseases. In this paper a new classification system for labyrinthine anomalies is introduced, based on this study of the literature.

    The study gives a short survey of the literature of frequently observed congenital anomalies in cattle and refers to data on cases of congenital anomalies registered in a veterinary practice over a period of 8 years and in an AI (artificial insemination) station of the Rinder-Union West (RUW) during 4 years. The frequency of congenital anomalies was estimated at 0.013% in the area of the RUW. In the veterinary practice a frequency of 0.51% was found. The most prevalent anomalies were seen in legs (39% in the veterinary practice and 21% in RUW) followed by congenital anomalies of the spine (9% in the veterinary practice and 17% in RUW). Arthrogryposes were most frequent among the anomalies of the legs with 65% (veterinary practice) and 39% (RUW), respectively, of all cases of registered leg anomalies in the respective area. Umbilical hernia and atresia of segments of the intestinum were seen in 8-30% of all registered cases. The frequency of congenital anomalies differed not significantly among paternal half sib groups. A questionnaire was proposed for the registration of congenital anomalies in progeny tests of AI bulls. A series of photographs showing the most prevalent congenital anomalies is supporting the registration form.

    2016-01-01

    Background/Purpose: This study aims to analyze the incidence and type of various associated anomalies among infants with extrahepatic biliary atresia (EHBA), compare their frequency with those quoted in the existing literature and assess their role in the overall management. Materials and Methods: A retrospective study was performed on 137 infants who underwent the Kasai procedure for EHBA during the past 12 years. The medical records were reviewed for the incidence and type of associated anomalies in addition to the details of the management of the EHBA. Results: Of the137 infants, 40 (29.2%) were diagnosed as having 58 anomalies. The majority of patients had presented in the 3rd month of life; mean age was 81 ± 33 days (range = 20-150 days). There were 32 males and 8 females; boys with EHBA had a higher incidence of associated anomalies. Of these 40 patients, 22 (37.9%) had vascular anomalies, 13 patients (22.4%) had hernias (umbilical-10, inguinal-3), 7 patients (12.1%) had intestinal malrotation, 4 patients (6.8%) had choledochal cyst, 1 patient (1.7%) had Meckel's diverticulum, 3 patients (5%) had undergone prior treatment for jejunoileal atresias (jejunal-2, ileal-1), 2 patients (3.4%) had undergone prior treatment for esophageal atresia and tracheoesophageal fistula, 2 patients (3.4%) had spleniculi, and 2 patients (3.4%) were diagnosed as having situs inversus. Conclusions: The most common associated anomalies in our study were related to the vascular variation at the porta hepatis and the digestive system. The existence of anomalies in distantly developing anatomic regions in patients with EHBA supports the possibility of a “generalized” insult during embryogenesis rather than a “localized” defect. In addition, male infants were observed to have significantly more associated anomalies as compared with the female infants in contrast to earlier reports. PMID:26862288

    2012-02-01

    This review defines the concepts of maternal-fetal (congenital) and vertical transmissions (mother-to-child) of pathogens and specifies the human parasites susceptible to be congenitally transferred. It highlights the epidemiological features of this transmission mode for the three main congenital parasitic infections due to Toxoplasma gondii, Trypanosoma cruzi and Plasmodium sp. Information on the possible maternal-fetal routes of transmission, the placental responses to infection and timing of parasite transmission are synthesized and compared. The factors susceptible to be involved in parasite transmission and development of congenital parasitic diseases, such as the parasite genotypes, the maternal co-infections and parasitic load, the immunological features of pregnant women and the capacity of some fetuses/neonates to overcome their immunological immaturity to mount an immune response against the transmitted parasites are also discussed and compared. Analysis of clinical data indicates that parasitic congenital infections are often asymptomatic, whereas symptomatic newborns generally display non-specific symptoms. The long-term consequences of congenital infections are also mentioned, such as the imprinting of neonatal immune system and the possible trans-generational transmission. The detection of infection in pregnant women is mainly based on standard serological or parasitological investigations. Amniocentesis and cordocentesis can be used for the detection of some fetal infections. The neonatal infection can be assessed using parasitological, molecular or immunological methods; the place of PCR in such neonatal diagnosis is discussed. When such laboratory diagnosis is not possible at birth or in the first weeks of life, standard serological investigations can also be performed 8-10 months after birth, to avoid detection of maternal transmitted antibodies. The specific aspects of treatment of T. gondii, T. cruzi and Plasmodium congenital infections are

    Congenital heart disease (CHD) patients have an increased prevalence of extracardiac congenital anomalies (CAs) and risk of neurodevelopmental disabilities (NDDs). Exome sequencing of 1213 CHD parent-offspring trios identified an excess of protein-damaging de novo mutations, especially in genes highly expressed in the developing heart and brain. These mutations accounted for 20% of patients with CHD, NDD, and CA but only 2% of patients with isolated CHD. Mutations altered genes involved in morphogenesis, chromatin modification, and transcriptional regulation, including multiple mutations in RBFOX2, a regulator of mRNA splicing. Genes mutated in other cohorts examined for NDD were enriched in CHD cases, particularly those with coexisting NDD. These findings reveal shared genetic contributions to CHD, NDD, and CA and provide opportunities for improved prognostic assessment and early therapeutic intervention in CHD patients.

    The aim of this study was to document some epidemiological features of termination of pregnancy for birth defects in Iran. We studied 603 pregnant women who were diagnosed/recommended for the termination of pregnancy as having a fetus with some types of birth defect(s). Most women (87.2 percent) had at least one ultrasound examination. The proportion of other screening tests including amniocentesis and genetic tests were 2.8 and 4.6 percent, respectively. Of 603 women, 201 terminated the pregnancy giving a prevalence rate of 33.3 percent (CI 95%: 29.6-37.6). The remaining 402 subjects were unable to get the permission for abortion because of untimely diagnosis/application for termination (20th week of pregnancy and/or later). Forty-eight percent of termination of pregnancies was performed before the 18th week of pregnancy. Neural tube defects, limb deformation, hydrops fetalis, hydrocephaly, and chromosomal anomalies including Down syndrome accounted proportionally for about 65 percent of defects eligible for abortion in the region. Although the rate of termination of pregnancy for birth defects is acceptable at the current situation in the country, more efforts should still be made to convince the community authorities to give more possibility and ease for the termination of pregnancy for congenital anomalies.

    Half of the malformations in the ear, nose, and throat region affect the ear. Malformations of the external ear (pinna or auricle with external auditory canal [EAC]) are collectively termed microtia. Microtia is a congenital anomaly that ranges in severity from mild structural abnormalities to complete absence of the external ear (anotia). Microtia occurs more frequently in males (∼2 or 3:1), is predominantly unilateral (∼70-90%), and more often involves the right ear (∼60%). The reported prevalence varies geographically from 0.83 to 17.4 per 10,000 births. Microtia may be genetic (with family history, spontaneous mutations) or acquired. Malformations of the external ear can also involve the middle ear and/or inner ear. Microtia may be an isolated birth defect, but associated anomalies or syndromes are described in 20 to 60% of cases, depending on study design. These generally fit within the oculo-auriculo-vertebral spectrum; defects are located most frequently in the facial skeleton, facial soft tissues, heart, and vertebral column, or comprise a syndrome (e.g., Treacher Collins syndrome). Diagnostic investigation of microtia includes clinical examination, audiologic testing, genetic analysis and, especially in higher grade malformations with EAC deformities, computed tomography (CT) or cone-beam CT for the planning of surgery and rehabilitation procedures, including implantation of hearing aids.

    Though congenital anomalies of the pancreas and pancreatic duct are relatively uncommon and they are often discovered as an incidental finding in asymptomatic patients, some of these anomalies may lead to various clinical symptoms such as recurrent abdominal pain, nausea and vomiting. Recognition of these anomalies is important because these anomalies may be a surgically correctable cause of recurrent pancreatitis or the cause of gastric outlet obstruction. An awareness of these anomalies may help in surgical planning and prevent inadvertent ductal injury. The purpose of this article is to review normal pancreatic embryology, the appearance of ductal anatomic variants and developmental anomalies of the pancreas, with emphasis on magnetic resonance cholangiopancreaticography and multidetector computed tomography.

    Background India lacks a national birth defects surveillance. Data on the prevalence of congenital anomalies are available mostly from hospital-based, cross-sectional studies. This is the first cohort study from India, where 2107 women were followed till pregnancy outcome, in order to measure the prevalence and types of congenital anomalies, their contribution to neonatal mortality, implications for surveillance, and the health service needs for prevention and management. Methods The study followed a cohort of 2107 pregnant women till outcome which was miscarriage, termination of pregnancy, live or stillbirth, neonatal and post-neonatal mortality. Case ascertainment of congenital anomalies was done through visual examination, followed by various investigations. Rates of congenital anomaly affected births were reported per 10 000 births. Health service needs were described through retrospective analysis of events surrounding the diagnosis of a congenital anomaly. Results Among 1822 births, the total prevalence of major congenital anomalies was 230.51 (170.99–310.11) per 10 000 births. Congenital heart defects were the most commonly reported anomalies in the cohort with a prevalence of 65.86 (37.72–114.77) per 10 000 births. Although neural tube defects were two and a half times less as compared to congenital heart defects, they were nevertheless significant at a prevalence of 27.44 (11.73–64.08) per 10 000 births. In this cohort, congenital anomalies were the second largest cause of neonatal deaths. The congenital anomaly prenatal diagnosis prevalence was 10.98 per 1000 births and the congenital anomaly termination of pregnancy rate was 4.39 per 1000 births. Conclusions This first cohort study from India establishes that the congenital anomaly rates were high, affecting one in forty four births in the cohort. The prevalence of congenital anomalies was identical to the stillbirth prevalence in the cohort, highlighting their public health importance. The results

    PURPOSE: This paper describes the surgical rehabilitation of a child with craniofacial anomalies, unilateral syndactyly, and partial unilateral cryptophthalmos associated with inferior colobomata of the iris and optic nerve and agenesis of the inferior rectus and inferior oblique muscles. The clinical presentation of cryptophthalmos is described. METHODS: The medical literature since the original description of cryptophthalmos in 1872 was reviewed to define patterns of inheritance and the incidence of associated anomalies. RESULTS: Including this patient, 149 case reports of cryptophthalmos were identified. In two families transmission from parent to child suggests dominant inheritance. None of the five dominant cases had any other anomalies, and all had bilateral complete cryptophthalmos. The incidence of cryptophthalmos in the remaining families is consistent with autosomal recessive inheritance. This group includes patients with bilateral, unilateral, and partial cryptophthalmos. Other anomalies are common, including those of the ear and nose, limbs, genitourinary system, and mouth and palate. Mortality in the perinatal period is associated with renal agenesis, laryngeal atresia, and pulmonary hypoplasia. CONCLUSIONS: Cryptophthalmos is a rare congenital anomaly with two patterns of inheritance.

    Previous studies have shown that over 40% of babies with Down syndrome have a major cardiac anomaly and are more likely to have other major congenital anomalies. Since 2000, many countries in Europe have introduced national antenatal screening programs for Down syndrome. This study aimed to determine if the introduction of these screening programs and the subsequent termination of prenatally detected pregnancies were associated with any decline in the prevalence of additional anomalies in babies born with Down syndrome. The study sample consisted of 7,044 live births and fetal deaths with Down syndrome registered in 28 European population-based congenital anomaly registries covering seven million births during 2000-2010. Overall, 43.6% (95% CI: 42.4-44.7%) of births with Down syndrome had a cardiac anomaly and 15.0% (14.2-15.8%) had a non-cardiac anomaly. Female babies with Down syndrome were significantly more likely to have a cardiac anomaly compared to male babies (47.6% compared with 40.4%, P < 0.001) and significantly less likely to have a non-cardiac anomaly (12.9% compared with 16.7%, P < 0.001). The prevalence of cardiac and non-cardiac congenital anomalies in babies with Down syndrome has remained constant, suggesting that population screening for Down syndrome and subsequent terminations has not influenced the prevalence of specific congenital anomalies in these babies.

    The health impact on populations residing in industrially contaminated sites (CSs) is recognized as a public health concern especially in relation to more vulnerable population subgroups. The aim of this study was to estimate the risk of congenital anomalies (CAs) in Italian CSs. Thirteen CSs covered by regional CA registries were investigated in an ecological study. The observed/expected ratios (O/E) with 90% confidence intervals (CI) for the total and specific subgroups of CAs were calculated using the regional areas as references. For the CSs with waste landfills, petrochemicals, and refineries, pooled estimates were calculated. The total number of observed cases of CAs was 7085 out of 288,184 births (prevalence 245.8 per 10,000). For some CSs, excesses for several CA subgroups were observed, in particular for genital and heart defects. The excess of genital CAs observed in Gela (O/E 2.36; 90% CI 1.73–3.15) is consistent with findings from other studies. For CSs including petrochemical and landfills, the pooled risk estimates were 1.10 (90% CI 1.01–1.19) and 1.07 (90% CI 1.02–1.13), respectively. The results are useful in identifying priority areas for analytical investigations and in supporting the promotion of policies for the primary prevention of CAs. The use of short-latency effect indicators is recommended for the health surveillance of the populations residing in CSs. PMID:28287452

    Zika virus (ZIKV) is an arbovirus belonging to flaviviridae family that includes Dengue, West Nile, and Yellow Fever among others. Zika virus was first discovered in 1947 in Zika forest of Uganda. It is a vector borne disease, which has been sporadically reported mostly from Africa, Pacific islands and Southeast Asia since its discovery. ZIKV infection presents as a mild illness with symptoms lasting for several days to a week after the bite of an infected mosquito. Majority of the patients have low grade fever, rash, headaches, joints pain, myalgia, and flu like symptoms. Pregnant women are more vulnerable to ZIKV infection and serious congenital anomalies can occur in foetus through trans-placental transmission. The gestation at which infection is acquired is important. Zika virus infection acquired in early pregnancy poses greater risk. There is no evidence so far about transmission through breast milk. Foetal microcephaly, Gillian Barre syndrome and other neurological and autoimmune syndromes have been reported in areas where Zika outbreaks have occurred. As infection is usually very mild no specific treatment is required. Pregnant women may be advised to take rest, get plenty of fluids. For fever and pain they can take antipyretics like paracetamol. So far no specific drugs or vaccines are available against Zika Virus Infection so prevention is the mainstay against this diseases. As ZIKV infection is a vector borne disease, prevention can be a multi-pronged strategy. These entail vector control interventions, personal protection, environmental sanitation and health education among others.

    The role of angiotensin in fluid and electrolyte and blood pressure homeostasis is well known. Recent developments indicate that angiotensin has a profound role not only in the developing urinary tract but also in the response of the urinary tract to specific noxious stimuli. Furthermore, the role of angiotensin II and its receptor has been understood quite poorly with respect to the developing renal unit. Knockout mice for the ATR2 gene show a significant incidence of congenital urinary tract anomalies. The congenital anomalies of the kidney and urinary tract (CAKUT) seen in these mice are very similar to the anomalies observed in humans. This has been supported further by the finding of an abnormality in the genetic sequence in patients with CAKUT. This article reviews experimental laboratory data as well as the potential implications for humans.

    Congenital fusion of the atlas with the odontoid process of the axis is a very rare condition caused by a segmental defect of the first cervical somite. Only 9 such cases have been reported in the literature to date. The bipartite atlas, another well-documented rare anomaly, has been observed in only 0.1% of the general population. We describe the first case of a 70-year-old male with both of these complex congenital anomalies.

    Ebstein anomaly accounts for 1% of all congenital heart disease. It is a right ventricular myopathy with failure of tricuspid valve delamination and highly variable tricuspid valve morphology that usually results in severe regurgitation. It is the only congenital heart lesion that has a range of clinical presentations, from the severely symptomatic neonate to an asymptomatic adult. Neonatal operation has high operative mortality, whereas operation performed beyond infancy and into adulthood has low operative mortality. Late survival and quality of life for hospital survivors are excellent for the majority of patients in all age brackets. Atrial tachyarrhythmias are the most common late complication. There have been more techniques of tricuspid repair reported in the literature than any other congenital or acquired cardiac lesion. This is largely due to the infinite anatomic variability encountered with this anomaly. The cone reconstruction of Ebstein anomaly can achieve near anatomic restoration of the tricuspid valve anatomy. Early and intermediate results with these repairs are promising. Reduced right ventricular function continues to be a challenge for some patients, as is the need for reoperation for recurrent tricuspid regurgitation. The purpose of this article is to outline the current standard of care for diagnosis and treatment of Ebstein anomaly and describe innovative strategies to address poor right ventricular function and associated right-sided heart failure.

    Congenital anomalies encompass a wide range of malformations that could affect various organs and tissues in the newborn and infant population. These disorders that involve defects in or injury to a developing fetus may be a result of genetic abnormalities or mutations, alterations in the intrauterine environment, irregularities in morphogenesis, or chromosomal aberration. The outcome of these defects could lead to minor anomalies or major malformations that are dependent on the complex processes between the prenatal deficit and postnatal environment. Often multiple malformations occur within the same fetus and give rise to a malformation syndrome. Since congenital anomalies are evident at birth, solutions must be found to improve the clinical state and quality of life that a newborn has to lead from infancy through adolescence into adulthood. Transplantation options in this age group are limited due to the shortage of organs and the discrepancy in adult donor size mismatch. Over the past 2 decades tremendous strides have been made in the research of biomaterials, stem cells, organ generation, and tissue engineering to provide viable solutions to a wide range of organ and tissue losses focusing on the adult population. This review intends to highlight the shortage of tissue and organs in neonates and infants with congenital malformations. This is also the first monograph that presents estimation of incidences of the congenital malformations based on an extensive literature search. It also outlines the challenges in clinical management of these entities and presents an organ-based demand for engineered tissues.

    Aim The first aim of this study was to evaluate the association between different subgroups of autism spectrum disorders (ASDs) (childhood autism, Asperger syndrome, and pervasive developmental disorder/pervasive developmental disorder – not otherwise specified [PDD/PDD-NOS]) and congenital anomalies. Second, we assessed the association among intellectually disabled children with ASDs in the subgroups of childhood autism and PDD/PDD-NOS. Method Nationwide population-based register data for children with a diagnosis of ASD (n=4449; 3548 males, 901 females) were collected during years 1987–2000 from the Finnish Hospital Discharge Register. Data on congenital anomalies were derived from the National Register of Congenital Malformations. Conditional logistic regression models were used as a statistical method. The association between ASD subgroups and congenital anomalies was stratified by the presence or absence of intellectual disability. Results Congenital anomalies occurred more frequently in all subgroups of ASD than in comparison participants (adjusted odds ratio [OR] for major congenital anomalies 1.8, 95% confidence interval [CI] 1.5–2.2, p<0.001). The association between congenital anomalies and childhood autism (OR 2.4, 95% CI 1.6–3.6, p<0.001) and between congenital anomalies and PDD/PDD-NOS (OR 3.7, 95% CI 2.4–5.7, p<0.001) among children with an intellectual disability was strong but remained significant also without intellectual disability (childhood autism: OR 1.7, 95% CI 1.3–2.3, p<0.001; PDD/PDD-NOS: OR 2.3, 95% CI 1.9–2.8, p<0.001). Interpretation The results suggest a significant association between ASDs and congenital anomalies regardless of the ASD subgroup. The association between childhood autism and PDD/PDD-NOS and congenital anomalies is stronger among children with intellectual disability is stronger than among those without intellectual disability. These results may have relevance in examining early risk factors in autism during

    Introduction: Congenital hypothyroidism (CH) may be significantly associated with congenital malformations. However, there is little evidence on the relationship between renal and urinary tract anomalies and CH. Objectives: The aim of this study was to compare the renal and upper urinary tract anomalies in children with and without primary CH (PCH). Patients and Methods: This case-control study was conducted on 200 children aged 3 months to 1 year, referring to Amir-Kabir hospital, Arak, Iran. One hundred children with PCH, as the case group, and 100 children without CH, as the control group, were selected. For all children, ultrasonography and other diagnostic measures (if necessary) were performed to evaluate renal and upper urinary tract anomalies (ureter and bladder). Results: The frequency of renal and upper urinary tract anomalies among 43 children with primary CH, with 83 cases (72.8%), was significantly higher than the frequency of anomalies among the 19 children in the control group, with 31 cases (27.1%) (OR = 3; CI 95%: 1.6-5.4; P = 0.001). Among the anomalies studied, only the differences in frequency of uretero-pelvic junction obstruction (UPJO) (OR = 6; CI 95%: 1.3-28; P = 0.018) and hydronephrosis (OR = 22; CI 95%: 5-95; P = 0.001) was significant between the two groups. Conclusion: Our study demonstrated that PCH is significantly associated with the frequency of congenital anomalies of the kidneys and upper urinary tracts. However, further studies are recommended to determine the necessity of conducting screening programs for anomalies of the kidneys and urinary tract in children with CH at birth. PMID:26693499

    The author has studied the congenital anomalies of the urogenital system according to the clinical data of the Nephrology Ward, District Hospital--Vratza, by means of urography, ascending pyelography and reno-vasography. A total of 1960 patients were examined and congenital anomalies of the urogenital system established in 167 (8, 5%). Congenital anomalies of the excretory system, according to the author, are more often met in females (59, 9%) as compated with males (40, 1%) and in left kidney (58, 6%) as compared with the right one (35, 9%). At the same time, the most frequent complication of renal embryopathies was established to be the inflammation process of urinary ducts and kidneys (41, 9%) urinary-calculus disease (19.1%) and endemic nephropathy (8, 9%). The combination of endemic nephropathy and congenital anomalies of the urogenital system is rare (1, 1%) and most likely by chance. The author admits that endemic nephropathy most probably is not causality with the congenital anomalies of the excretory system.

    Imaging plays an important role in determining indications of cochlear implantation and choosing candidates for the procedure in children. Temporal high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) can display precisely the complex anatomic structure of inner ear. Although HRCT permits detailed imaging of bony structures, MRI gives valuable information about membranous labyrinth, internal acoustic canal, and vestibulocochlear nerve. Magnetic resonance imaging examination of the brain should be performed at the same time to evaluate any coexistent brain parenchymal abnormality. These imaging modalities are complementary methods in evaluating congenital inner ear anomalies. The aim of this pictorial essay is to reviewing temporal HRCT and MRI findings of congenital inner ear anomalies.

    Background In our institutional experience treating pediatric choledochal cysts over the last 12 years, we noted 7/32 patients (21.9%) had comorbid congenital cardiac anomalies. This association has not been previously described other than in isolated case reports. We aimed to quantify this association on a national level. Materials and Methods We queried the 2009 Healthcare Cost and Utilization Project Kids' Inpatient Database. Patients with a diagnosis of choledochal cyst (ICD-9-CM 75169, 75162, 75160) or biliary atresia (75161) were identified. Cardiac anomalies were defined using the Clinical Classification Software code (CCS 213). Comorbid choledochal cysts or biliary atresia and congenital cardiac anomalies were quantified in both infant (<12 mos) and child (1–18 yrs) subpopulations. Results Of 1,646 estimated discharges for patients with choledochal cysts, 506 (30.7%) were for patients who also had congenital cardiac anomalies, compared to 2.6% in the general hospitalized population (χ2, p<0.0001). The frequency of congenital cardiac anomalies was lower in 1,973 hospitalizations for biliary atresia (13.8%) than in those for patients with choledochal cysts (χ2, p<0.0001). Cardiac anomalies were detected in 44.9% of choledochal cyst hospitalizations for infants <12 months (vs. 3.44% general hospitalized population; χ2, p<0.0001), but in 6.9% of for children ages 1–18 yrs (vs. 1.3% general hospitalized population; χ2, p<0.0001). Conclusions A strong association was observed between pediatric choledochal cysts and congenital cardiac anomalies that more commonly manifests in infancy. When choledochal cysts are diagnosed either prenatally or in infancy, we suggest echocardiographic screening for cardiac anomalies, which may impact timing of surgery and anesthetic planning.

    PHACE syndrome represents the association of large infantile hemangiomas of the head and neck with brain, cerebrovascular, cardiac, ocular, and ventral/midline defects. Cardiac and cerebrovascular anomalies are the most common extracutaneous features of PHACE, and they also constitute the greatest source of potential morbidity. Congenital heart disease in PHACE is incompletely described, and this study was conducted to better characterize its features. This study of the International PHACE Syndrome Registry represents the largest central review of clinical, radiology, and pathology data for cardiovascular anomalies in PHACE patients to date. 62/150 (41%) subjects had intracardiac, aortic arch, or brachiocephalic vessel anomalies. Aberrant origin of a subclavian artery was the most common cardiovascular anomaly (present in 31/150 (21%) of subjects). Coarctation was the second most common anomaly, identified in 28/150 (19%), and can be missed clinically in PHACE patients because of the frequent association of arch obstruction with aberrant subclavian origin. 23/62 (37%) subjects with cardiovascular anomalies required procedural intervention. A higher percentage of hemangiomas were located on the left side of the head/neck in patients with coarctation (46% vs. 39%); however, hemangioma distribution did not predict the presence of cardiovascular anomalies overall. In conclusion, PHACE is associated with a high risk of congenital heart disease. Cardiac and aortic arch imaging with detailed assessment of arch patency and brachiocephalic origins is essential for any patient suspected of having PHACE. Longitudinal investigation is needed to determine the long-term outcomes of cardiovascular anomalies in PHACE. PMID:24079520

    Several studies on pregnancy-associated cancers have suggested an association with congenital anomalies in offspring. Previous studies have included maternal cancers diagnosed up to 2 years after pregnancy; however, long latency periods of some cancers mean that cancers diagnosed many years postpartum might have been present during pregnancy in a preclinical state. This paper considers the association between maternal cancers diagnosed from 2 years prior to pregnancy until the mother reaches 50 years of age, and congenital anomalies, as diagnosed at birth or within the first year of life. The current population-based study looks at associations of cancers in mothers with congenital anomalies in their children. Children were followed up from birth to diagnosis of a congenital anomaly, death, emigration or end of follow-up (whichever occurred first). A total of 56,016 children (2.6%) were considered exposed to a maternal cancer of any type; and they had a hazard ratio (HR) of 1.04 (95% confidence interval [CI]: 1.00, 1.09) compared with unexposed children. The greatest HR was seen among children whose mothers had been diagnosed with cancers before or during pregnancy (HR: 1.37, 95% CI: 1.07, 1.75). Similar results were seen when paternal cancers were used as a ‘negative control’. Statistically significant associations were seen for some specific congenital anomalies of organ systems (congenital anomalies of the musculoskeletal system [HR: 1.13, 95% CI: 1.02, 1.25]) and for some specific types of maternal cancer (leukaemia [HR: 1.31, 95% CI: 1.01, 1.61], The results of the main analyses suggest a small increase in risk of congenital anomalies in offspring of mothers diagnosed with cancer from 2 years before pregnancy, until the mother reaches 50 years of age; with the greatest increase seen for exposure in the pre-pregnancy and pregnancy period. These results may reflect shared causes for some cancers and some congenital anomalies. The similar results seen for

    Female workers in the semiconductor industry have higher risks of subfertility and spontaneous abortion, but no studies exploring male-mediated developmental toxicity have been published. This study aimed to investigate whether the offspring of male workers employed in the semiconductor manufacturing industry had an increased risk of death with congenital anomalies. The 6,834 male workers had been employed in the eight semiconductor companies in Taiwan between 1980 and 1994. We identified the live born children with or without congenital anomalies of the workers using the National Birth and Death Registries from the Department of Health, Taiwan. Multiple logistic regression models were used to estimate the odds ratios (OR) of birth outcomes and deaths, controlling for infant sex, maternal age, and paternal education. A total of 5,702 children were born to male workers during the period 1980-1994. There were increased risks of deaths with congenital anomalies (adjusted OR, 3.26; and 95% confidence interval [CI], 1.12-9.44) and heart anomalies (OR, 4.15; 95% CI, 1.08-15.95) in the offspring of male workers who were employed during the two months before conception. We found evidence of a possible link between paternal preconception exposure of semiconductor manufacturing and an increased risk of congenital anomalies, especially of the heart. The possible etiological basis needs to be corroborated in further research.

    Serotonin reuptake inhibitors (SRIs) are often prescribed during pregnancy. Previous studies that found an increased risk of congenital anomalies, particularly congenital heart anomalies (CHA), with SRI use during pregnancy have created concern among pregnant women and healthcare professionals about the safety of these drugs. However, subsequent studies have reported conflicting results on the association between CHA and SRI use during pregnancy. These discrepancies in the risk estimates can potentially be explained by genetic differences among exposed individuals. In this review, we explore the potential pharmacogenetic predictors involved in the pharmacokinetics and mechanism of action of SRIs, and their relation to the risk of CHA. In general, the risk is dependent on the maternal concentration of SRIs and the foetal serotonin level/effect, which can be modulated by the alteration in the expression and/or function of the metabolic enzymes, transporter proteins and serotonin receptors involved in the serotonin signalling of the foetal heart development. Pharmacogenetics might be the key to understanding why some children exposed to SRIs develop a congenital heart anomaly and others do not. PMID:27529241

    While childhood psoriasis is fairly common, congenital psoriasis appears to be rare and has not been well characterized. We present a patient with histologically confirmed congenital psoriasis. By reviewing the literature, we aim to both define this disease and compare it to infantile and childhood psoriasis. Electronic searches found articles reporting patients with biopsy-proven congenital psoriasis. We recorded clinical features, such as family history, anatomic involvement, and disease severity. We compared these data with previous descriptions of infantile and childhood psoriasis. We included nine patients with congenital psoriasis in our analysis. No patient had a first-degree family history of psoriasis. While the face, scalp, chest, and trunk were frequently involved, the buttocks generally were spared. Several patients had persistent disease despite therapy. In this series, congenital psoriasis differed from infantile and childhood psoriasis in several respects. Specifically, congenital psoriasis was associated with a lower prevalence of relevant family history, which could increase over time, and a different pattern of anatomic involvement, which may reflect exposure to age-associated environmental factors. Although several patients with congenital psoriasis had severe disease, this likely represents publication bias. Additional reports of congenital psoriasis with extended follow-up are needed to better characterize this condition.

    Introduction. Congenital anomalies are important causes of childhood death, chronic illness, and disability in many countries. Congenital malformations are rapidly emerging as one of the major worldwide problems. Aim. To study the percentage of various congenital anomalies among the patients admitted in Department of Pediatric Surgery at a tertiary care centre over a period of four years from 2011 to 2015 in our centre. Results. Neural tube defects were found to be the most common anomalies in 24.3% of the children admitted. Other common anomalies were anorectal malformation (20.7%), tracheoesophageal fistula (20%), and intestinal obstruction (14.84%). Majority (60.5%) of the patients were males. Conclusion. Congenital malformations are rapidly emerging as one of the major worldwide problems as they can result in long-term disability, which may have significant impacts on individuals, families, health-care systems, and societies. Regular antenatal visits and prenatal diagnosis are recommended for prevention, early intervention, and even planned termination, when needed. PMID:28280513

    A baby with the complete form of pentalogy of Cantrell was delivered at 33 weeks of gestation. The hallmark of this syndrome is ectopia cordis (EC) with omphalocele. Even though a fetal diagnosis was made at 14 weeks, parents have decided to continue with the pregnancy. Early antenatal ultrasonographic diagnosis is essential as survival depends mostly on the EC, associated cardiac anomalies and degree of thoraco-abdominal defect. Fetal diagnosis of this lethal anomaly before viability gives the parents an option of termination. PMID:24049753

    Sirenomelia, alternatively known as 'mermaid syndrome' is a very rare congenital deformity in which the legs are fused together, giving them the appearance of the tail of a mermaid'. Other birth defects are always associated with sirenomelia, most commonly abnormalities of the kidneys, large intestines, and genitalia. The present case is a one of sirenomelia associated with an absent right kidney, mild left hydronephrosis, single umbilical artery, and severe oligohydramnios. We discuss the findings, relative to the present literature and related etiopathogenesis.

    This study was designed with an aim to detect the congenital anomalies appear to be linked to and in conjunction with hydrocephalus fetuses in Sudan, when ultrasound is used to exam fetuses in the second and third trimesters of pregnancy. This prospective cohort study was performed from December 2011 to December 2013, in a group consists of 5000 single gestation pregnant Sudanese women. In all cases, maternal ages were 35 years up to 48 years; mean age of 42.5 years. Pelvic; obstetric ultrasound scanning protocol used should meet the standards established by the American Institute of Ultrasound in Medicine (AIUM) for scanning in the second and third trimesters of pregnancy. Statistical Package for the Social Sciences (SPSS) was used to analyze the results. Diagnosed hydrocephalus cases (0.4%) were found to be associated with other fetal anomalies as aqueduct stenosis (45%), spina bifida (30%), Arnold-Chiari malformation (20%) and Dandy-Walker malformation (5%). The incidence of congenital anomalies and hydrocephalus in Sudanese fetuses showed considerable variation among different regions of Sudan. Hydrocephalus is associated with certain congenital anomalies. In agreement with previous studies, hydrocephalus is predominantly in male rather than female fetuses. The prevalence of fetal anomalies and hydrocephalus are within previously reported ranges.

    In this study, we analyze the association between industrial activity and the occurrence of 34 congenital anomalies. We selected 21 counties in Argentina during 1982-1994 and examined a total of 614,796 births in these counties in consecutive series. We used the International Standard Industrial Classification of All Economic Activities (United Nations, 1968) as an indicator of exposure to 80 specific industrial activities. Incidence rate ratios for each congenital anomaly were adjusted by the socioeconomic level of the county according to a census index of social deprivation. For a given exposure/anomaly association to be considered as significant and relevant, the exposure had to be a statistically significant risk for the occurrence of the anomaly and an increase in the birth prevalence rate of the congenital anomaly type involved had to be observed in those counties where the putative causal activity was being performed. Significant associations (p < 0.01) were identified between textile industry and anencephaly, and between the manufacture of engines and turbines and microcephaly. These observations are consistent with previous reports on occupational exposure, and their further investigation by means of case-control studies is recommended. PMID:10706523

    Leber's congenital amaurosis (LCA), a type of congenital blindness, is clinically and genetically heterogeneous and often associated with systemic anomalies. We report on two sisters who were born to a consanguineous couple and had retinitis pigmentosa-like pigmented retinal lesions, alternating exotropia, bilateral cataracts, and anomalous coarse facies characterized by deformed skull with narrow forehead, low anterior hairline, hypertelorism, short philtrum, thin upper lip, and prominent jaw; cerebellar vermis hypoplasia; dilatation of the fourth ventricle; severe mental retardation; tremor; brisk deep tendon reflexes and abnormal behavior; and skeletal abnormalities such as limited extension of elbow and/ or finger joints and talipes equinovalgus. Skin defect and renal anomalies were seen in only one patient. Our patients are the first familial LCA associated with cerebellar vermis hypoplasia, and the disease involving particular multiple systemic anomalies may represent a distinct clinical entity.

    Congenital heart malformations are the most common of all birth defects, affecting 0.5-1% of all live births. Some of these malformations are due to genetic anomalies. Patterns of autosomal dominant, autosomal recessive and X-linked inheritance have been described. Mitochondrial inheritance and chromosomal anomalies can also be responsible for congenital heart malformations. Several genes for congenital heart defects have been identified. We review current knowledge on the genetic etiology of congenital heart disease.

    Background Over the years, great efforts have been made to record the frequency of orofacial clefts in different populations. However, very few studies were able to account for the etiological and phenotypic heterogeneity of these conditions. Thus, data of cases with syndromic orofacial clefts from large population-based studies are infrequent. Methods Clinically recognized and notified syndromes and associations including cleft lip with or without cleft palate and other congenital anomalies were selected from the Hungarian Congenital Abnormality Registry (HCAR) between 1973 and 1982 and prevalence rates were calculated. Results Of 3,110 cases reported as having orofacial clefts, 653 had multiple congenital abnormalities. Of these, 60 (9.2%) had a known etiology (monogenic: 25 or 3.8%, chromosomal: 31 or 4.7%, teratogenic: 4 or 0.6%). Seventy-three subjects (11.2%) had schisis in addition to the oral cleft. Skeletal anomalies were the most common malformations among cases with cleft lip with/without cleft palate (CL/P) and cleft palate (CP). Disorders of the central nervous system and cardiovascular malformations were also frequently associated. Conclusion Surveillance systems, such as the HCAR, provide useful information about prevalence rates of congenital anomalies in a population. However, in a field where new syndromes are being discovered and classifications regularly updated, these rates should only be accepted as provisional. PMID:15985166

    Biventricular repair is usually difficult to achieve in patients who have right atrial isomerism, which is typically associated with other complex cardiac anomalies. The procedure can be used in patients who have balanced ventricular structures. Herein, we report a successful surgical reconstruction, including biventricular repair, in a 4-year-old boy. The child's right atrial isomerism was associated with double-outlet right ventricle, a large atrial septal defect, a subaortic ventricular septal defect, valvular and infundibular pulmonary stenosis, left persistent superior vena cava, and hemiazygos continuation of an interrupted inferior vena cava. Balanced ventricles enabled biventricular repair, which we consider to be preferable to the Fontan procedure in such circumstances.

    Preduodenal portal vein is a rare congenital anomaly that causes high intestinal obstruction. The authors report two interesting cases of preduodenal portal vein that were diagnosed as having congenital duodenal obstruction. As there is a high potential for surgical risk, this anomaly is of special interest to the surgeon and should be kept in mind. Here, we discuss the clinical presentation, diagnosis and management along with a review of the literature.

    Approximately 1 in 200 individuals and 20 percent to 30 percent of those in whom any major structural malformation is found will have 2 or more serious and potentially unrelated birth defects. In addition to the challenges that multiple malformations create for affected persons, their families, and the health care system, appropriate surveillance of such complex patterns can be a concern for birth defects registries. This paper provides examples of how monitoring of multiple anomalies can be beneficial from clinical and public health perspectives; presents a staged approach to documentation of such defects, including suggestions for their coding; describes the types of patterns in which they occur; and discusses some of the unique issues that arise with respect to statistical analysis of multiple versus isolated birth defects.

    A retrospective study was performed on all patients with congenital adrenal hyperplasia (CAH) who were followed up at the King Hussein Medical Center (KHMC), Amman, Jordan, during the period from January 1996 to June 2006. The aim was to evaluate the clinical features, special problems, and corrective interventions for these patients. The records of 73 children (39 were genetic females and 34 were genetic males) with CAH were reviewed in the study. The age of the patients at last follow-up was between five months and 18 years. Diagnostic criteria for CAH were typical clinical features of the illness (salt loss, dehydration, virilization, macrogenitosomia, ambiguous genitalia, and accelerated growth) and typical hormonal abnormalities (decreased serum cortisol and elevated serum 17-hydroxyprogesterone). There were 62 patients with classical presentation; among them, salt-wasting (SW) form was seen in 41 patients (66%). There were 5 patients with the nonclassic form, while 6 others had cryptic presentation. Seven patients (9%) had hypertension, mostly due to salt-retaining CAH. Among the 39 females with CAH, 27 had developed mental anomalies of the external genitalia; 20 of them underwent surgical interventions of their external genitalia. Fourteen genetically female patients were wrongly diagnosed as 'male sex' at birth due to severe virilization. Seven of them were reassigned 'female sex' socially, legally, and surgically; the parents of one of them (a four-year-old girl) wanted the surgical intervention postponed for two to three years. Hysterectomy and gonadectomy were carried out for 6 of the other 7 patients who chose to keep the male gender. Our study indicates that newborns with developmental anomalies of the external genitalia should be diagnosed as early as possible so that medical, psychological, and social complications are minimized. A neonatal screening program for such a disorder can identify infants at risk for the development of life

    Stridor is a serious complication of congenital neuraxial anomalies, which though, can get completely resolved with early neurosurgical correction of the anomaly. However, stridor relief may or may not be achieved soon after surgery. Persistent postoperative stridor can potentially cause extubation failure that may be difficult to handle in small children. There are no extubation guidelines for difficult pediatric airways as yet, and fewer appropriate airway-assist devices for routine use. Management of an infant with occipital encephalocele, hydrocephalus and bilateral abductor vocal cord palsy, who developed post-extubation respiratory distress due to stridor is discussed, together with the relevant tracheal extubation issues in such cases.

    The development of multidetector computed tomography has triggered a revolution in the study of the aorta and other large vessels and has replaced angiography in the diagnosis of congenital anomalies of the aortic arch, particularly vascular rings. The major advantage of multidetector computed tomography is that it permits clear 3-dimensional assessment of not only vascular structures, but also airway and esophageal compression. The current update aims to summarize the embryonic development of the aortic arch and the developmental anomalies leading to vascular ring formation and to discuss the current diagnostic and therapeutic role of multidetector computed tomography in this field.

    Knowledge of what causes developmental disorders, including congenital structural defects/anomalies, in the newborn population, facilitates the choice of further investigations, therapy and rehabilitation, allows the use of appropriate prophylaxis against comorbidities, makes it possible to specify prognosis, as well as provide reliable family counselling (both pre- and postnatal). Attempting to formulate a clinical diagnosis of a specific congenital anomaly syndrome, with or without dysmorphic features, based on history and detailed physical examination, remains crucial for the selection of the right genetic testing. Modern methods of molecular cytogenetics and molecular biology are targeted in nature (microdeletion MLPA, single gene sequencing) or are capable of analyzing the genome as a whole (array CGH, newgeneration sequencing). Especially the latter techniques are now causing a rapid increase of diagnostic efficacy across different age groups, including newborns.

    Congenital anomalies of the kidneys and urinary tract are a major cause of chronic and end-stage renal failure in children. The molecular mechanisms having been elaborated, there is now growing evidence that kidney function is to a large extent determined genetically at an early stage. Assessment of kidney function is an important tool in clinical medicine and is feasible in utero. Postnatally, determination of absolute glomerular filtration rate and also of split and excretory renal function play an important role in the determination of treatment and prognosis. This is supplemented by other biochemical, molecular and interventional prognostic factors, which are of help in preservation of kidney survival by minimizing modulating factors. If chronic or terminal renal failure ensues in childhood or even in early infancy, however, improved medical care has led to encouraging results, ultimately influencing the motivation in the care of children with congenital anomalies of the kidney and urinary tract.

    "Anatomy of the abnormal"-a branch of surgical anatomy-deals with relations of an anomaly to surrounding entities. Here, lateral congenital anomalies of the pharyngeal apparatus are examined; their relations to entities of the neck can be explained embryologically. Location of embryonic pharyngeal arches, clefts, and pouches in the adult is presented and terminology of these anomalies (fistulas, sinuses, cysts) is defined. First "cleft and pouch" anomalies relate with the parotid and facial nerve. Second cleft and pouch anomalies course deeply to second arch structures and superficially to third arch structures. Consequently, they relate with hypoglossal and glossopharyngeal nerves and internal and external carotid arteries. Third cleft and pouch anomalies pass deep to third arch entities and superficial to those of the fourth arch and relate with glossopharyngeal, hypoglossal, superior and recurrent laryngeal nerves, and the internal carotid artery. The complicated course of fourth cleft and pouch anomalies brings them into relationship with glossopharyngeal, hypoglossal, superior and recurrent nerves, internal carotid, aorta, and subclavian arteries. Found superficially are veins (external and anterior jugular, common facial, communicating), nerves (transverse cervical, great auricular, mandibular, cervical branches of facial), and relevant spinal nerves (e.g., accessory). Knowledge of these anatomical relations helps prevent anatomical complications.

    Uterine anomalies are due either to primary congenital malformations, or to secondary traumatic lesions of the intrauterine cavity as well as to pathology of the endometrium. The latter two etiologic factors create difficulties in the correct diagnosis of a congenital malformation and despite the convincing hysterosalpingographic findings a false diagnosis of a congenital malformation and despite the convincing hysterosalpingographic findings a false diagnosis is frequent. On the other hand the various degrees of uterine anomalies cannot always convince the gynecologist to undertake a plastic operation where the results for future fertility are doubtful. In our experience the extensive beneficial use of a variety of selected IUDs for the correction of intrauterine lesions also resulted in the correction of the size and shape of the uteri, previously diagnosed as malformed. The preliminary results of treatment in 110 cases of uterine anomalies after the application of a selected IUD combined with the administration of high doses of gestagens, showed an overall satisfactory improvement or complete reconstruction to a normal uterus in 86 (78%) of the cases. Higher fertility rate, better pregnancy outcome, correct diagnosis of the existing malformation, and safer decisions for further correction have also been attributed to the beneficial effects of the above treatment.

    Congenital Anomalies in Canada 2013: A Perinatal Health Surveillance Report is the second national surveillance report from the Public Health Agency of Canada dedicated to congenital anomalies. It provides comprehensive data on congenital anomalies in Canada, focussing on 6 categories of congenital anomalies: Down syndrome, neural tube defects, congenital heart defects, orofacial clefts, limb deficiency defects and gastroschisis. The report presents national-level birth prevalence data and temporal trends, provincial and territorial estimates, and international comparisons. Known risk factors, prevalence-related impacts of prenatal diagnosis and preventative measures are also discussed.

    STUDY OBJECTIVE--The aims were (1) to assess whether termination of pregnancy after prenatal screening by ultrasound affected the prevalence of congenital anomalies at birth, and (2) to examine the trend of this pattern over time. DESIGN--This study deals with congenital anomalies, possibly detectable prenatally or at birth, which were classified as isolated and multiple anomalies; chromosomal anomalies were not included. The prevalence rates of congenital anomalies at birth were determined from case registration data in the Marseille district, France, from the registry of congenital malformations (Eurocat no 22), which covers 23,500 births a year. The chi 2 test for homogeneity in proportions was used to test whether the differences in the total prevalence rates were significant over time. SETTING--The population was defined as all children born to parents living in the Marseille district between January 1 1984 and December 31 1990. PATIENTS--Among the 164,509 pregnancy outcomes monitored during the study, 1795 children with a single congenital anomaly and 288 with multiple congenital anomalies detectable at birth were assessed. MEASUREMENTS AND MAIN RESULTS--The percentage of pregnancy terminations was higher in the case of multiple anomalies (16%) than with single ones (7.5%). Leaving aside the lethal birth defects, this percentage became 7.9% in the case of multiple anomalies and 4.3% with isolated ones. A significant increase (p < 0.001) occurred over the seven year study period in the total percentage of terminations because of isolated anomalies but not in that involving multiple ones. The increase observed in the former case was found to be mainly attributable to an increase in the number of terminations of pregnancy undertaken because of anomalies which were either lethal or associated with very low survival rates (p < 0.001). CONCLUSIONS--Termination of pregnancy after prenatal ultrasound examination was found to have a definite impact on the prevalence

    The co-occurrence of hearing impairment and visual dysfunction is devastating. Most deaf-blind etiologies are genetically determined, the commonest being Usher syndrome (USH). While studies of the congenitally deaf population reveal a variable degree of visual problems, there are no effective ophthalmic screening guidelines. We hypothesized that children with congenital sensorineural hearing loss (SNHL) and vestibular impairment were at an increased risk of having USH. A retrospective chart review of 33 cochlear implants recipients for severe to profound SNHL and measured vestibular dysfunction was performed to determine the ocular phenotype. All the cases had undergone ocular examination and electroretinogram (ERG). Patients with an abnormal ERG underwent genetic testing for USH. We found an underlying ocular abnormality in 81.81% (27/33) of cases; of which 75% had refractive errors, and 50% of those patients showed visual improvement with refractive correction. A total of 14 cases (42.42%; 14/33) had generalized rod-cone dysfunction on ERG suggestive of Usher syndrome type 1, confirmed by mutational analysis. This work shows that adding vestibular impairment as a criterion for requesting an eye exam and adding the ERG to detect USH increases the chances of detecting ocular anomalies, when compared with previous literature focusing only on congenital SNHL.

    The lack of laboratory tests for the diagnosis of most of the congenital anomalies renders the physical examination of the case crucial for the diagnosis of the anomaly; and the cases in the diagnostic phase are mostly being evaluated in the light of the literature knowledge. In this respect, for accurate diagnosis, ,it is of great importance to provide the decision maker with decision support by presenting the literature knowledge about a particular case. Here, we demonstrated a methodology for automated scanning and determining of the phenotypic features from the case reports related to congenital anomalies in the literature with text and natural language processing methods, and we created a framework of an information source for a potential diagnostic decision support system for congenital anomalies.

    We studied the effectiveness of extracorporeal shock wave lithotripsy (ESWL) in the treatment of stones in kidneys with congenital anomalies to determine factors that may affect the results. Patients found to have renal calculi in kidneys with different types of congenital anomalies were treated using ESWL. All patients were investigated by intravenous urography (IVU) to confirm the diagnosis. J stents were inserted prior to therapy in renal units with calculi exceeding 1.5 cm in diameter. Complications encountered and factors affecting success using this treatment modality were analysed. Twenty-five patients (18 males, 7 females) were studied between August 1988 and July 2005. There were nine patients with horseshoe kidneys, eight with ectopic kidneys, three with malrotated kidneys, two with duplex renal system, and one patient each with polycystic kidneys and hypoplastic kidney. The IVU showed 31 isolated calyceal or renal pelvic stones with mean stone burden of 1.44cc. All 25 patients were treated by lithotripsy. Twenty-four (77.4%) renal units (in 19 patients) were completely cleared of stones, 2 (6.5%) renal units (2 patients) were partially cleared of calculi and the procedures failed in 5 (16.1%) renal units (4 patients). Out of five renal units in which the procedures failed, open surgery was performed in three renal units and percutaneous nephrolithotomy (PCNL) was performed in two. None of the 25 patients developed any major complications. No significant adverse changes in renal function tests were observed at 3-month follow-up. The stone-free rate was influenced and reduced by stone size and location in the pelvi-calyceal system. Calculi in kidneys with congenital anomalies may be treated successfully by ESWL as a first-line therapy in the majority of patients. With position modifications, localization of stones may be facilitated and disintegrated. The outcome in patients so treated does not differ significantly from that in those with normal kidneys.

    Congenital anomalies of the coronary arteries, although uncommon, have the potential to cause serious myocardial damage, ischaemic cardiomyopathy, and sudden cardiac death. This article summarises aspects of care for these patients in the outpatient setting, including clinical history and physical examination findings, ancillary testing, decision-making regarding the need for surgical intervention, and recommendations for physical activity. Although there are limited data regarding some of these recommendations, it is hoped that these can be used as an initial benchmark against which further data will lead to a more evidence-based approach.

    Congenital anomalies of the kidney and urinary tract (CAKUT) cover a wide range of structural malformations that result from defects in the morphogenesis of the kidney and/or urinary tract. These anomalies account for about 40-50 % of children with chronic kidney disease worldwide. Knowledge from genetically modified mouse models suggests that single gene mutations in renal developmental genes may lead to CAKUT in humans. However, until recently, only a handful of CAKUT-causing genes were reported, most of them in familial syndromic cases. Recent findings suggest that CAKUT may arise from mutations in a multitude of different single gene causes. We focus here on single-gene causes of CAKUT and their developmental origin. Currently, more than 20 monogenic CAKUT-causing genes have been identified. High-throughput sequencing techniques make it likely that additional CAKUT-causing genes will be identified in the near future.

    This article presents the case of a mother who is planning a home birth with a midwife with the shared knowledge that the fetus would have congenital anomalies of unknown severity. We discuss the right of women to choose home birth, the caregivers' duty to the infant, and the careproviders' dilemma about how to respond to this request. The ethical duties of concerned careproviders are explored and reframed as professional obligations to the mother, infant, and their profession at large. Recommendations are offered based on this case in order to clarify the considerations surrounding not only home birth of a fetus with anticipated anomalies, but also to address the ethical obligations of caregivers who must navigate the unique tension between respecting the mother's wishes and the duty of the careproviders to deliver optimal care.

    The clinical features of ring chromosome 6 include central nervous system anomalies, growth retardation, facial dysmorphism and other congenital anomalies. Ring chromosome 6 occurs rarely and manifests as various phenotypes. We report the case of mosaic ring chromosome 6 by conventional karyotyping in a 7-day-old male infant diagnosed with a large patent ductus arteriosus (PDA) with hypoplasia of aortic valve and aortic arch. These have not been previously reported with ring chromosome 6. He recovered from heart failure symptoms after ligation of the PDA. He showed infantile failure to thrive and delayed milestone in a follow-up evaluation. To the best of our knowledge, this is the first report of a Korean individual with ring chromosome 6 and hemodynamically significant PDA.

    Fukuyama-type congenital muscular dystrophy (FCMD), the second most common childhood muscular dystrophy in Japan, is characterized by the association with severe brain anomalies such as pachygyria and focal interhemispheric fusion. Conventional imaging techniques such as X-ray CT scan and MRI are ineffective for visualization of these brain surface anomalies. Here we investigated the efficacy of three-dimensional (3-D) reconstruction of brain surface MR images for the detection of brain anomalies in FCMD patients. 3-D brain surface MR images clearly visualized anomalies of cerebral gyrus such as pachygyria, as well as focal interhemispheric fusion. In addition, reconstructed horizontal images visualized structural derangement such as abnormal protrusion of white matter into gray matter. MR image abnormalities were confirmed by autopsy in 1 patient. These abnormalities were never observed in Duchenne muscular dystrophy (DMD) patients. Our results indicate the efficacy of the present method for the differential diagnosis between FCMD and DMD with severe mental retardation, which is essential for the genetic study to identify the causative gene of FCMD.

    This review article explores sports and recreational precautions in children with solitary kidneys. In 2001, the American Academy of Pediatrics published recommendations for activity in children with medical conditions. Those with solitary kidneys were graded a "qualified yes": no restriction in noncontact sports, and individual assessment for limited-contact, contact, and collision sports. Recent trauma data suggest that classification according to the degree of contact is inaccurate. We propose an updated, data-driven classification of sports or recreation according to the risk of high-grade renal trauma or loss of renal unit. Given the paucity of literature on the topic and lack of consensus, children with congenital renal anomalies should exercise caution in both sports and recreation.

    Human Cytomegalovirus (HCMV) infection still represents the most common potentially serious viral complication in humans and is a major cause of congenital anomalies in infants. This study is aimed to detect HCMV in infants with congenital anomalies. Study subjects consisted of infants born with neural tube defect, hydrocephalus and microcephaly. Fifty serum specimens (20 males, 30 females) were collected from different hospitals in Khartoum State. The sera were investigated for cytomegalovirus specific immunoglobin M (IgM) antibodies using enzyme-linked immunosorbent assay (ELISA), and for Cytomegalovirus DNA using polymerase chain reaction (PCR). Out of the 50 sera tested, one patient’s (2%) sample showed HCMV IgM, but with no detectable DNA, other 4(8.2 %) sera were positive for HCMV DNA but with no detectable IgM. Various diagnostic techniques should be considered to evaluate HCMV disease and routine screening for HCMV should be introduced for pregnant women in this setting. It is vital to initiate further research work with many samples from different area to assess prevalence and characterize HCMV and evaluate its maternal health implications. PMID:26862356

  6. Prenatal exposure to tetrachloroethylene-contaminated drinking water and the risk of congenital anomalies: a retrospective cohort study

    PubMed Central

    2009-01-01

    Background Prior animal and human studies of prenatal exposure to solvents including tetrachloroethylene (PCE) have shown increases in the risk of certain congenital anomalies among exposed offspring. Objectives This retrospective cohort study examined whether PCE contamination of public drinking water supplies in Massachusetts influenced the occurrence of congenital anomalies among children whose mothers were exposed around the time of conception. Methods The study included 1,658 children whose mothers were exposed to PCE-contaminated drinking water and a comparable group of 2,999 children of unexposed mothers. Mothers completed a self-administered questionnaire to gather information on all of their prior births, including the presence of anomalies, residential histories and confounding variables. PCE exposure was estimated using EPANET water distribution system modeling software that incorporated a fate and transport model. Results Children whose mothers had high exposure levels around the time of conception had an increased risk of congenital anomalies. The adjusted odds ratio of all anomalies combined among children with prenatal exposure in the uppermost quartile was 1.5 (95% CI: 0.9, 2.5). No meaningful increases in the risk were seen for lower exposure levels. Increases were also observed in the risk of neural tube defects (OR: 3.5, 95% CI: 0.8, 14.0) and oral clefts (OR 3.2, 95% CI: 0.7, 15.0) among offspring with any prenatal exposure. Conclusion The results of this study suggest that the risk of certain congenital anomalies is increased among the offspring of women who were exposed to PCE-contaminated drinking water around the time of conception. Because these results are limited by the small number of children with congenital anomalies that were based on maternal reports, a follow-up investigation should be conducted with a larger number of affected children who are identified by independent records.

    Morphological studies of congenital anomalies have mainly focused on abnormal shape (i.e. malformation) and thus on disturbed organogenesis. However, in regard to postnatal functions of organs that develop through branching mechanisms, organ size is another important morphological feature. These organs consist of a large number of structural and functional units, such as nephrons in the kidney, and the total number of these units, that is approximately proportional to the organ size, has been shown to vary widely among individuals. Organ-specific cells are differentiated and organized to form structural units and realize organ-specific functions during the histogenetic period (i.e. from mid-gestation to the early postnatal period). The total number of units is attained at the end of histogenesis and determines the total functional capacity, including the functional reserve of the organ, and thus may be related to predispositions to postnatal organ-based diseases, because the functional reserve decreases during the course of life and eventually become short of the minimum requirement of each organ. Therefore, it may be hypothesized that a smaller number of units of organs at the end of histogenesis is one of the predisposing factors for postnatal diseases (i.e. a form of unnoticed but late-manifested congenital anomalies), in this era of extended longevity. However, the mechanisms that control the total number of units in each organ during histogenesis and the possible relationship among the numbers of units in different organs remain unknown. Here, we review our trials based on the above hypothesis in order to (1) mathematically analyze the morphometric data of the different organs in fetuses to elucidate relationship among developing organs, (2) analyze the developing neuro-immuno-endocrine network as a series of mechanisms to systemically correlate the histogenesis of multiple organs, and (3) examine the maternal environment, including dietary fat, as a factor to

    In a nearly two-year-old ram, descending from a breeding trial to investigate the effects of shortness of the lower jaw (brachygnathia inferior), a congenital cardiac anomaly was observed. At the age often months the affected animal, a cross breed of Cameroon Sheep and East Friesian Milk Sheep, showed exercise-induced respiratory distress for the first time. Auscultation revealed a loud systolic heart murmur (grade 5) on both sides of the thorax, most prominent over the left third intercostal space at shoulder height. Postmortem examination of the ram's heart showed a pentalogy of Fallot, consisting of a pulmonic stenosis, a ventricular septal defect, an overriding aorta, a right ventricular hypertrophy and a patent foramen ovale. A genetic defect has to be considered as a possible reason.

    A seven-month-old, entire, male miniature schnauzer dog was referred with acute vomiting, inappetence and depression primarily as a result of a gastric foreign body (pine cones). During investigations, thoracic radiographs revealed increased volume of the right lung lobes, deviated cardiomediastinal structures and elevation of the heart from the sternum. Thoracic computed tomography revealed left cranial lung lobe hypoplasia and extension of the right cranial lung parenchyma across the midline to the left hemithorax. Branches of the right pulmonary vessels and bronchi also crossed the midline and extended to the left caudal lung lobe. These findings suggested that the right and left lungs were fused. In humans this finding is consistent with horseshoe lung, which is an uncommon congenital malformation. To the authors' knowledge, this case represents the first report of such a pulmonary anomaly in a dog.

    An accessory penis is a very rare anomaly. Only five cases have been reported thus far to our knowledge. We present the case of a child aged 2 years and 10 months who had a penis-like structure (containing phallus and glans) attached to the right buttock. Associated anomalies were a non-communicating type of colonic duplication, a paramedian stenosed anal opening, a horse-shoe kidney, posterior urethral valves, scoliosis of the lumbo-sacral spine, polydactyly and equino-varus deformity of the right foot. As far as we can tell, this is the first report of an accessory penis associated with colonic duplication and other congenital anomalies.

    Recent advancement in ultrasonographic evaluation has prompted early detection and diagnosis of congenital anomalies in the kidney and urinary tract (CAKUT) in the asymptomatic phase. Consequently, early surgical intervention has become possible in the asymptomatic phase for the purpose of controlling manifestations early, thereby avoiding renal functional deterioration. However, some lesions detected by ultrasonography have been shown to often resolve or disappear without intervention. Thus, it has become more important to identify and understand the natural history of CAKUT. For the precise evaluation of the results of surgical intervention, one must understand the maturational process of renal function during infancy. Without considering this process, we cannot differentiate the renal significance of the surgical management from the natural course of CAKUT. Recent advancement in the field of radioisotopic studies has also made a major contribution to the more precise assessment of renal function. Recent progress in the understanding of the pathophysiology and the natural history of CAKUT has helped rationalize its treatment and management. Improvement in the surgical techniques and tools, together with improvements in pediatric anesthesiology, have made an appreciably positive impact on the outcome. Herein, we present the emerging concepts in the urological management of CAKUT, specifically, multicystic dysplastic kidney, vesicoureteral reflux, congenital hydronephrosis, ectopic ureters and ureteroceles.

    Renal damage in children has been found to be more congenital in origin than was previously thought. Congenital anomalies of the kidney and urinary tract (CAKUT) involve renal dysplasia, renal hypoplasia, urinary tract obstruction and vesicoureteral reflux. CAKUT are sometimes bilateral and different types often coexist. Depending on their types and severity, children with CAKUT often have varying degrees of a reduced number of nephrons at birth. CAKUTare now the leading cause of renal failure in children. Children with renal dysplasia or obstructive uropathy may have abnormal renal tubules, and tend to lose essential water and sodium in urine. This can lead to poor body growth unless they are supplemented with water and sodium. Children with severe ureteric reflux often develop urinary infection and renal scarring. Renal scarring can further increase the risk of renal failure in children who already have other CAKUTand fewer nephrons than normal. Hypertension and proteinuria may develop in children with renal dysplasia and further aggravate renal function unless they are treated. Recent advances in the understanding and management of CAKUT make it possible for children with CAKUT to grow normally, have fewer complications such as urinary infection, have longer renal survival, and survive even with end-stage renal diseases through renal replacement therapy.

    Waardenburg syndrome (WS) is an inherited autosomal dominant genetic disorder presenting variable penetrance and expressivity, with an estimated prevalence of 1:42,000. Clinical characteristics of WS include lateral displacement of the internal eye canthus, hyperplasia of the medial portion of the eyebrows, prominent and broad nasal base, congenital deafness, pigmentation of the iris and skin, and white forelock. A 24-year-old male patient, previously diagnosed with WS, was referred to the Special Needs Dental Clinic of Sacred Heart University, Bauru, Brazil. Parents reported that the patient was experiencing self-mutilation, particularly in the oral region. He presented multiple congenital anomalies, including anophthalmia, mental retardation, low-set ears, and leg deformities. Clinical oral examination revealed hypodontia, abnormalities in dental morphology, extensive dental caries, periodontal disease, and fistulae. Extensive scars on the tongue, lips, and hands caused by self-mutilation were also observed. In accordance with his family and neurologist, full-mouth extraction under general anesthesia was performed, especially considering his severe self-aggressive behavior and the necessity to be fed with soft-food diet due to his inability to chew. After the surgical procedure, a significant reduction in the patient's irritability and gain of weight were reported in the follow-ups of 30, 60, and 180 days.

    Objective To describe the clinical phenotype and genetics of equine Multiple Congenital Ocular Anomalies (MCOA) syndrome in PMEL17 (Silver) mutant ponies. Animals studied Five presumably unrelated ponies. Procedures The ponies were examined under field conditions in their barn by slit lamp biomicroscopy, indirect ophthalmoscopy, and applanation tonometry. Blood was collected and genomic DNA extracted for MCOA genotyping using the PMEL17ex11 marker. Results One pony solely presented with temporal ciliary body cysts, suggestive of the less severe Cyst phenotype of MCOA; the animal was heterozygous at the MCOA locus. Multiple bilateral anterior segment anomalies were identified in four ponies, consistent with the more severe MCOA phenotype characterized by cornea globosa, iris hypoplasia, encircling granula iridica along the pupillary ruff, and cataracts. These animals were homozygous for the mutant MCOA allele. Four of the ponies had a silver dapple or chocolate coat color with white or flaxen manes and tails. Silver dappling was masked by the palomino coloring of a 5th pony that was homozygous at the MCOA locus. Conclusions The MCOA syndrome can be seen in ponies. The results of both clinical evaluation and genotyping resembled the previously described MCOA of both Rocky Mountain and Kentucky Mountain Saddle horses. PMID:21929608

    Fetal hydronephrosis is the most common anomaly detected on antenatal ultrasound, affecting 1-5% of pregnancies. Postnatal investigation has the major aim in detecting infants with severe urinary tract obstruction and clinically significant urinary tract anomalies among the heterogeneous universe of patients. Congenital uropathies are frequent causes of pediatric chronic kidney disease (CKD). Imaging techniques clearly contribute to this purpose; however, sometimes, these exams are invasive, very expensive, and not sufficient to precisely define the best approach as well as the prognosis. Recently, biomarkers have become a focus of clinical research as potentially useful diagnostic tools in pediatric urological diseases. In this regard, recent studies suggest a role for cytokines and chemokines in the pathophysiology of CAKUT and for the progression to CKD. Some authors proposed that the evaluation of these inflammatory mediators might help the management of postnatal uropathies and the detection of patients with high risk to developed chronic kidney disease. Therefore, the aim of this paper is to revise general aspects of cytokines and the link between cytokines, CAKUT, and CKD by including experimental and clinical evidence.

    A series of 22 women who suffered from mushroom poisoning while pregnant have been identified among adults receiving treatment between 1960 and 1993 in a specialist clinic in Budapest, Hungary. In most cases, the poisonings were attributed to Amanita phalloides, verna, and related species. Of these, 20 went to term, and data were collected on gestational age, birth weight, and both major and minor congenital anomalies. Mean birth weight (but not gestational age) was lower than in the control series, suggesting that maternal poisoning may have led to intrauterine growth retardation. Two children were identified with major abnormalities (one of whom had fetal alcohol syndrome related to alcohol abuse by the mother). The prevalences of both major and minor anomalies were similar to the prevalence in the matched control group and to the rate in a more recent control series examined according to the same protocols. However, the statistical power to detect teratogenic effects is limited, especially as only five of the mothers suffered the poisoning episode during the first trimester.

    The anatomical patterns and frequency of occurrence of congenital coronary anomalies (CCA) in a Central European cohort has not yet been studied. The angiographic data of 7,694 consecutive patients undergoing coronary arteriography at the Albert Szent-Györgyi Medical University, Szeged, Hungary, from 1984 to 1994 were analyzed. CCA were found in 103 patients (1.34% incidence). Ninety-eight of them (95.2%) had anomalies of origin and distribution, and five (4.8%) had coronary artery fistulae. The incidence was the highest for the separate origin of left descending artery and left circumflex from the left sinus of Valsalva (52.42%). Anomalous origin of the left circumflex coronary artery from the right coronary was 8.7% while from the right sinus of Valsalva 18.4%. CCA, which may be associated with potentially serious events, such as ectopic coronary origin from the opposite aortic sinus (1.9%) and single coronary arteries (3.88%), were not frequent. The incidence of CCA in the Central European cohort under study was similar to that of the largest North American study. The anatomic classification presented can be useful from both clinical and surgical standpoints.

    A review was made of experimental methods available to produce congenital hydrocephalus by teratogenic methods. Radiation, infections, trypan blue, hypervitaminosis A, salicylates and nutritional deficiencies were considered. In the course of prenatal zinc deficiency experiments, congenital hydrocephalus was frequently encountered and histologic sections were made of many representative specimens. Details of the findings are described, among them various types of aqueduct stenosis or obileration. Although these anomalies suggest that occlusion of the aqueduct is the cause of the enlargement of the ventricular system it was noted that there was also ventricular dilatation caudal to the stenotic point of the aqueduct. Hydrocephalus without aqueductal stenosis has also been observed in experimental animals. It seems possible that some cases of congenital hydrocephalus attributed to aqueductal stenosis are examples of hydrocephalus with secondary block of the aqueduct.

    Objectives To estimate the prevalences of the main groups of congenital anomalies and to assess their trend over time. Design Population-based study of prevalences. Setting The Basque Country, Spain. Participants All births and all congenital anomalies diagnosed prenatally, at birth or during the first year of age, in all hospitals of the country, from 1999 to 2008. Main outcomes measures Total diagnosed prevalences and prevalences at birth of all chromosomal and non-chromosomal anomalies, Down's syndrome, anomalies of the nervous system, urinary, limbs, digestive system and congenital heart defects. Results Mean age (SD) of women at childbirth and the proportion of them over 35 years of age shifted from 32.1 (4.5) years, with 18.3% in 1999–2001, to 32.3 (4.7) years, with 23.9% in 2006–2008. Between 1999 and 2008, 991 cases of chromosomal anomalies and 3090 of non-chromosomal anomalies were diagnosed, which yields, respectively, total prevalences of 5.2‰ and of 16.2‰. Among chromosomal anomalies, Down's syndrome is the most frequent (2.9‰). With marginal statistical significance, the results point at an increasing trend in total diagnosed chromosomal anomalies, but a decreasing one in prevalences at birth. Among non-chromosomal congenital anomalies, congenital heart defects are the most frequent (5.2‰) one. Rates of all non-chromosomal, urinary and limb anomalies grew during the study period, whereas those of congenital heart defects and anomalies of the digestive system did not change significantly. Conclusions In the Basque Country, rates of chromosomal anomalies are higher than the overall estimated prevalence in European countries, and continue to increase slightly, which may be related to the rise in maternal age. Rates of non-chromosomal anomalies are within the European frequent range of values, and the increases observed need to be checked in the following years. PMID:24589823

    Previously, patients with chronic renal failure and major congenital anomalies of the lower urinary tract (often with urinary diversion) were thought to be poor candidates for renal transplantation. Pre-transplant evaluation and possible urinary reconstruction are essential in these patients to achieve successful renal transplantation. Ten patients, including 7 adults, presented with congenital anomalies of the lower urinary tract that were responsible for renal failure. Percutaneous suprapubic cystostomy aided in the assessment of bladder function. Undiagnosed posterior urethral valves were found in 2 adults. Patients with exstrophy, neurogenic bladder or a contracted bladder (with augmentation cystoplasty) had urinary drainage into the bladder at the time of renal transplantation. Sometimes an imperfect bladder can be used for urinary drainage with transplantation but, otherwise, intestinal conduits are still a viable alternative.

    Chromosomal microarray (CMA) is increasingly utilized for genetic testing of individuals with unexplained developmental delay/intellectual disability (DD/ID), autism spectrum disorders (ASD), or multiple congenital anomalies (MCA). Performing CMA and G-banded karyotyping on every patient substantially increases the total cost of genetic testing. The International Standard Cytogenomic Array (ISCA) Consortium held two international workshops and conducted a literature review of 33 studies, including 21,698 patients tested by CMA. We provide an evidence-based summary of clinical cytogenetic testing comparing CMA to G-banded karyotyping with respect to technical advantages and limitations, diagnostic yield for various types of chromosomal aberrations, and issues that affect test interpretation. CMA offers a much higher diagnostic yield (15%–20%) for genetic testing of individuals with unexplained DD/ID, ASD, or MCA than a G-banded karyotype (∼3%, excluding Down syndrome and other recognizable chromosomal syndromes), primarily because of its higher sensitivity for submicroscopic deletions and duplications. Truly balanced rearrangements and low-level mosaicism are generally not detectable by arrays, but these are relatively infrequent causes of abnormal phenotypes in this population (<1%). Available evidence strongly supports the use of CMA in place of G-banded karyotyping as the first-tier cytogenetic diagnostic test for patients with DD/ID, ASD, or MCA. G-banded karyotype analysis should be reserved for patients with obvious chromosomal syndromes (e.g., Down syndrome), a family history of chromosomal rearrangement, or a history of multiple miscarriages.

    Congenital anomalies of the kidney and urinary tract (CAKUT) are common birth defects and the leading cause of end-stage renal disease in children. There is a wide spectrum of renal abnormalities, from mild hydronephrosis to more severe cases, such as bilateral renal dysplasia. The etiology of the majority of cases of CAKUT remains unknown, but there is increasing evidence that genomic imbalance contributes to the pathogenesis of CAKUT. Advances in human and mouse genetics have contributed to increased understanding of the pathophysiology of CAKUT. Mutations in genes involved in both transcription factors and signal transduction pathways involved in renal development are associated with CAKUT. Large cohort studies suggest that copy number variants, genomic, or de novo mutations may explain up to one-third of all cases of CAKUT. One of the major challenges to the use of genetic information in the clinical setting remains the lack of strict genotype–phenotype correlation. However, identifying genetic causes of CAKUT may lead to improved diagnosis of extrarenal complications. With the advent of decreasing costs for whole genome and exome sequencing, future studies focused on genotype–phenotype correlations, gene modifiers, and animal models of gene mutations will be needed to translate genetic advances into improved clinical care.

    Despite the clinical significance of balanced chromosomal abnormalities (BCAs), their characterization has largely been restricted to cytogenetic resolution. We explored the landscape of BCAs at nucleotide resolution in 273 subjects with a spectrum of congenital anomalies. Whole-genome sequencing revised 93% of karyotypes and demonstrated complexity that was cryptic to karyotyping in 21% of BCAs, highlighting the limitations of conventional cytogenetic approaches. At least 33.9% of BCAs resulted in gene disruption that likely contributed to the developmental phenotype, 5.2% were associated with pathogenic genomic imbalances, and 7.3% disrupted topologically associated domains (TADs) encompassing known syndromic loci. Remarkably, BCA breakpoints in eight subjects altered a single TAD encompassing MEF2C, a known driver of 5q14.3 microdeletion syndrome, resulting in decreased MEF2C expression. We propose that sequence-level resolution dramatically improves prediction of clinical outcomes for balanced rearrangements and provides insight into new pathogenic mechanisms, such as altered regulation due to changes in chromosome topology.

    Gray-scale ultrasound is the diagnostic technique of choice in patients with suspected or known renal disease. Knowledge of the normal and abnormal sonographic morphology of the kidney and urinary tract is essential for a successful diagnosis. Conventional sonography must always be complemented by Doppler sampling of the principal arterial and venous vessels. B-mode scanning is performed with the patient in supine, prone or side position. The kidney can be imaged by the anterior, lateral or posterior approach using coronal, transverse and oblique scanning planes. Morphological parameters that must be evaluated are the coronal diameter, the parenchymal thickness and echogenicity, the structure and state of the urinary tract, and the presence of congenital anomalies that may mimic a pseudomass. The main renal artery and the hilar-intraparenchymal branches of the arterial and venous vessels should be accurately evaluated using color Doppler. Measurement of intraparenchymal resistance indices (IP, IR) provides an indirect and quantitative parameter of the stiffness and eutrophic or dystrophic remodeling of the intrarenal microvasculature. These parameters differ depending on age, diabetic and hypertensive disease, chronic renal glomerular disease, and interstitial, vascular and obstructive nephropathy.

    Hepatocyte nuclear factor 1beta (HNF1beta) abnormalities have been recognized to cause congenital anomalies of the kidney and urinary tract (CAKUT), predominantly affecting bilateral renal malformations. To further understand the spectrum of HNF1beta related phenotypes, we performed HNF1B gene mutation and deletion analyses in Japanese patients with renal hypodysplasia (n = 31), unilateral multicystic dysplastic kidney (MCDK; n = 14) and others (n = 5). We identified HNF1B alterations in 5 out of 50 patients (10%). De novo heterozygous complete deletions of HNF1B were found in 3 patients with unilateral MCDK. Two of the patients showed contralateral hypodysplasia, whereas the other patient showed a radiologically normal contralateral kidney with normal renal function. Copy number variation analyses showed 1.4 Mb microdeletions involving the whole HNF1B gene with breakpoints in flanking segmental duplications. We also identified 1 novel truncated mutation (1007insC) and another missense mutation (226G>T) in patients with bilateral hypodysplasia. HNF1B alterations leading to haploinsufficiency affect a diverse spectrum of CAKUT. The existence of a patient with unilateral MCDK with normal renal function might provide genetic insight into the etiology of these substantial populations of only unilateral MCDK. The recurrent microdeletions encompassing HNF1B could have a significant impact on the mechanism of HNF1B deletions.

    Magnetic resonance angiography and digital substraction angiography (DSA) findings in a case with a rare congenital thoracoabdominal aortic hypoplasia and common celiamesenteric trunk variation with occlusion of infrarenal abdominal aorta are described here. To our knowledge, this aortic anomaly has not been previously described in the English literature. DSA is the optimum imaging modality for determination of aortic hypoplasia, associated vascular malformations, collateral vessels, and direction of flow within vessels.

  13. Molecular karyotyping by array CGH in a Russian cohort of children with intellectual disability, autism, epilepsy and congenital anomalies

    2012-01-01

    Background Array comparative genomic hybridization (CGH) has been repeatedly shown to be a successful tool for the identification of genomic variations in a clinical population. During the last decade, the implementation of array CGH has resulted in the identification of new causative submicroscopic chromosome imbalances and copy number variations (CNVs) in neuropsychiatric (neurobehavioral) diseases. Currently, array-CGH-based technologies have become an integral part of molecular diagnosis and research in individuals with neuropsychiatric disorders and children with intellectual disability (mental retardation) and congenital anomalies. Here, we introduce the Russian cohort of children with intellectual disability, autism, epilepsy and congenital anomalies analyzed by BAC array CGH and a novel bioinformatic strategy. Results Among 54 individuals highly selected according to clinical criteria and molecular and cytogenetic data (from 2426 patients evaluated cytogenetically and molecularly between November 2007 and May 2012), chromosomal imbalances were detected in 26 individuals (48%). In two patients (4%), a previously undescribed condition was observed. The latter has been designated as meiotic (constitutional) genomic instability resulted in multiple submicroscopic rearrangements (including CNVs). Using bioinformatic strategy, we were able to identify clinically relevant CNVs in 15 individuals (28%). Selected cases were confirmed by molecular cytogenetic and molecular genetic methods. Eight out of 26 chromosomal imbalances (31%) have not been previously reported. Among them, three cases were co-occurrence of subtle chromosome 9 and 21 deletions. Conclusions We conducted an array CGH study of Russian patients suffering from intellectual disability, autism, epilepsy and congenital anomalies. In total, phenotypic manifestations of clinically relevant genomic variations were found to result from genomic rearrangements affecting 1247 disease-causing and pathway

    Background In the 1990s, congenital anomalies were reported among children whose fathers had served aboard a Norwegian missile torpedo boat (MTB). The Royal Norwegian Navy asked the University of Bergen to look into this problem as one part of a general health and work environment surveillance. Aims To estimate any increased risk of having children with congenital anomalies and having stillborn children among the offspring of workers that had served aboard the MTB and to investigate possible differences in exposure and other risk factors between these groups. Methods Data from a cross‐sectional study among all current employees of the Norwegian Navy (n = 2265, response rate 58%) were analysed. Results The prevalence ratio of having a child with congenital malformations associated with working on the ship was 4.0 (95% CI 1.9 to 8.6). The prevalence ratio of having a child who was stillborn or died within one week was 4.1 (95% CI 1.7 to 9.9). Conclusion Service aboard the MTB was associated with an increased risk of having children with congenital birth defects and having children that were stillborn. The causes of these findings are unknown. PMID:16421386

    Congenital renal anomalies (CRAs) detected in adults include horseshoe kidney (HK), crossed renal ectopia, and malrotation. Congenital renal anomalies are rare, and renal lesions associated with CRA are rarer. Thirteen patients (11 men and 2 women) were referred to our center with renal masses in the context of CRAs, which included HK (10 cases), crossed renal ectopia (2 cases), and a pelvic kidney (1 case). The mean age at diagnosis was 60 years (37-76 years). All patients were treated with open surgery; 10, partial nephrectomies; 4, radical nephrectomies; and 1, nephroureterectomy with division of the renal isthmus. Pathology ranged from benign (simple cortical cysts, chronic pyelonephritis with secondary hydronephrosis) to malignant (12 cases of renal cell carcinomas [RCCs] and 1 case of urothelial carcinoma). Two patients of HKs presented with bilateral renal masses. The size of the RCC ranged from 2.5 to 13 cm. There were 11 cases of clear cell RCC, 1 case of papillary RCC (type 1), and 1 case of urothelial carcinoma. All the cases of RCC had negative surgical margins. Follow-up available in all patients ranged from 1 month up to 49 months. None of the patients developed any locoregional recurrences or distant metastases. In this patient cohort, the most common congenital anomaly associated with RCC is HK. All tumors behaved in an indolent fashion with prognosis related to pathologic tumor stage. Partial nephrectomy is a safe and effective procedure in appropriately selected patients.

    The study was conducted to plan for a community-health campaign to inform working-class Filipinos about the causes and prevention of orofacial clefting. Prenatal micronutrients may play a role in preventing orofacial clefting. Therefore, women's practices and perspectives on barriers to and facilitators of micronutrient supplementation were elicited. A total of 43 women and 22 health care workers were interviewed. Barriers to taking supplements included side effects, late prenatal care, the view that micronutrients are medications, inadequate supply, and health care workers who were unaware that prenatal vitamin supplements prevent congenital anomalies. The main facilitator was women's understanding that prenatal micronutrients improve the physical well-being of both mother and child. Given that women view having healthy babies as a reason to take micronutrients and that the health care workers lacked knowledge related to the use of micronutrients to prevent congenital anomalies, uptake of prenatal micronutrient supplementation programs may improve by specifically promoting the health benefit of preventing congenital anomalies.

    Animal studies and epidemiological evidence suggest an association between prenatal exposure to drinking water with elevated nitrate (NO3-N) concentrations and incidence of congenital anomalies. This study used Geographic Information Systems (GIS) to derive individual-level prenatal drinking-water nitrate exposure estimates from measured nitrate concentrations from 140 temporally monitored private wells and 6 municipal water supplies. Cases of major congenital anomalies in Kings County, Nova Scotia, Canada, between 1988 and 2006 were selected from province-wide population-based perinatal surveillance databases and matched to controls from the same databases. Unconditional multivariable logistic regression was performed to test for an association between drinking-water nitrate exposure and congenital anomalies after adjusting for clinically relevant risk factors. Employing all nitrate data there was a trend toward increased risk of congenital anomalies for increased nitrate exposure levels though this was not statistically significant. After stratification of the data by conception before or after folic acid supplementation, an increased risk of congenital anomalies for nitrate exposure of 1.5–5.56 mg/L (2.44; 1.05–5.66) and a trend toward increased risk for >5.56 mg/L (2.25; 0.92–5.52) was found. Though the study is likely underpowered, these results suggest that drinking-water nitrate exposure may contribute to increased risk of congenital anomalies at levels below the current Canadian maximum allowable concentration.

    Leber's congenital amaurosis is a hereditary clinical disorder that may be associated with several different diseases. This study consists of a retrospective review of 43 cases. Twenty of our patients had fundus appearances that resembled retinitis pigmentosa. Five had normal-appearing fundi. The remainder had other, previously reported fundus abnormalities, with the exception of two patients who demonstrated a new fundus finding, a nummular pigmentary pattern. Other associated eye anomalies included cataracts, keratoconus, ptosis, and strabismus. The most frequent systemic associations were mental retardation, cystic renal disease, skeletal disorders, and hydrocephalus.

    Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, otitis media, and sinusitis. Lacrimal duct obstruction and fistula were managed successfully with endoscopic dacryocystorhinostomy (DCR) which is a good alternative to lacrimal probing or open DCR in such a case.

    Biallelic PIGT variants were previously reported in seven patients from three families with Multiple Congenital Anomalies-Hypotonia Seizures Syndrome 3 (MCAHS3), characterized by epileptic encephalopathy, hypotonia, global developmental delay/intellectual disability, cerebral and cerebellar atrophy, craniofacial dysmorphisms, and skeletal, ophthalmological, cardiac, and genitourinary abnormalities. We report a novel homozygous PIGT missense variant c.1079G>T (p.Gly360Val) in two brothers with several of the typical features of MCAHS3, but in addition, pyramidal tract neurological signs. Notably, they are the first patients with MCAHS3 without skeletal, cardiac, or genitourinary anomalies. PIGT encodes a crucial subunit of the glycosylphosphatidylinositol (GPI) transamidase complex, which catalyzes the attachment of proteins to GPI-anchors, attaching the proteins to the cell membrane. In vitro studies in cells from the two brothers showed reduced levels of GPI-anchors and GPI-anchored proteins on the cell surface, supporting the pathogenicity of the novel PIGT variant.

    Three patients (two of them siblings) had Leber's congenital amaurosis and cerebellar disease. Despite blindness and severe motor deficits, all three patients have achieved relatively normal intellectual and psychosocial milestones. Computed tomographic scans, performed in two patients, demonstrated hypoplasia of the cerebellar vermis in both. The presence of delayed speech and motor development as well as structural CNS abnormalities in children with Leber's congenital amaurosis does not necessarily imply that severe intellectual impairment will be present.

    The aim of the present investigation was to search for a reduction in birth prevalence estimates of 52 selected types of congenital anomalies, associated with folic acid fortification programs in Chile, Argentina, and Brazil. The material included 3,347,559 total births in 77 hospitals of the three countries during the 1982-2007 period: 596,704 births (17 hospitals) in Chile, 1,643,341 (41 hospitals) in Argentina, and 1,107,514 (19 hospitals) in Brazil. We compared pre- and post-fortification rates within each hospital and the resulting Prevalence Rate Ratios (PRRs) were pooled by country. Statistically significant reductions in birth prevalence estimates after fortification were observed for neural tube defects (NTDs), septal heart defects, transverse limb deficiencies, and subluxation of the hip. However, only the reduction of NTDs appeared to be associated with folic acid fortification and not due to other factors, because of its consistency among the three countries, as well as with previously published reports, and its strong statistical significance. Among the NTDs, the maximum prevalence reduction was observed for isolated cephalic (cervical-thoracic) spina bifida, followed by caudal (lumbo-sacral) spina bifida, anencephaly, and cephalocele. This observation suggests etiologic and pathogenetic heterogeneity among different levels of spina bifida, as well as among different NTD subtypes. We concluded that food fortification with folic acid prevents NTDs but not other types of congenital anomalies.

    From the stand point of radiographic analysis most of the complex cyanotic congenital heart diseases (CHD), can be divided into those associated with decreased or increased pulmonary vascularity. Combination of a specific cardiac configuration and status of lung vasculature in a clinical context allows plain film diagnosis to be predicted in some CHD. Correlation of the position of the cardiac apex in relation to the visceral situs is an important information that can be obtained from the plain film. This information helps in gathering information about the atrio-ventricular, ventricular arterial concordance or discordance. Categorization of the cyanotic heart disease based on vascularity is presented below. Thorough understanding of cardiac anatomy by different imaging methods is essential in understanding and interpreting complex cardiac disease. Basic anatomical details and background for interpretation are provided in the previous parts of this presentation. PMID:27630924

    Congenitally missing teeth (CMT), or as usually called hypodontia, is a highly prevalent and costly dental anomaly. Besides an unfavorable appearance, patients with missing teeth may suffer from malocclusion, periodontal damage, insufficient alveolar bone growth, reduced chewing ability, inarticulate pronunciation and other problems. Treatment might be usually expensive and multidisciplinary. This highly frequent and yet expensive anomaly is of interest to numerous clinical, basic science and public health fields such as orthodontics, pediatric dentistry, prosthodontics, periodontics, maxillofacial surgery, anatomy, anthropology and even the insurance industry. This essay reviews the findings on the etiology, prevalence, risk factors, occurrence patterns, skeletal changes and treatments of congenitally missing teeth. It seems that CMT usually appears in females and in the permanent dentition. It is not conclusive whether it tends to occur more in the maxilla or mandible and also in the anterior versus posterior segments. It can accompany various complications and should be attended by expert teams as soon as possible. PMID:25709668

    The initial stages in the rehabilitation of a male child with severe microblepharon, corneal opacities, bilateral facial clefts, bilateral complete cleft lip and palate, and unilateral syndactyly are described. Review of the literature suggests that severe microblepharon is associated with other craniofacial anomalies, and often the child is stillborn or retarded. Surviving children have been abandoned because of their appearance. The child described in this case appears to be unique because his intelligence is normal, and, to our knowledge, this is the first reported case of penetrating keratoplasty after reconstruction of functional eyelids. The principal problems after corneal grafting appear to have been chronic partial exposure due to inadequate lid length and a poor Bell's reflex and the persistence of a rim of vascularized fibrous tissue around the corneal graft. Future reconstructive surgery is outlined.

    AIMS: The aim of this study was to quantify the risk of major congenital anomaly, and to assess the influence of peri-conception HbA(1c) and other clinical and socio-demographic factors on the risk of congenital anomaly occurrence in offspring of women with type 1 and type 2 diabetes diagnosed before pregnancy. METHODS: This was a population-based cohort study using linked data from registers of congenital anomaly and diabetes in pregnancy. A total of 401,149 singleton pregnancies (1,677 in women with diabetes) between 1996 and 2008 resulting in live birth, fetal death at ≥20 weeks' gestation or termination of pregnancy for fetal anomaly were included. RESULTS: The rate of non-chromosomal major congenital anomaly in women with diabetes was 71.6 per 1,000 pregnancies (95% CI 59.6, 84.9), a relative risk of 3.8 (95% CI 3.2, 4.5) compared with women without diabetes. There was a three- to sixfold increased risk across all common anomaly groups. In a multivariate analysis, peri-conception glycaemic control (adjusted OR [aOR] 1.3 [95% CI 1.2, 1.4] per 1% [11 mmol/mol] linear increase in HbA(1c) above 6.3% [45 mmol/mol]) and pre-existing nephropathy (aOR 2.5 [95% CI 1.1, 5.3]) were significant independent predictors of congenital anomaly. Associations with gestation at booking (aOR 1.1 [95% CI 1.0, 1.1]) and parity (aOR 1.6 [95% CI 1.0, 2. 5]) were not significant. Unadjusted risk was higher for women from deprived areas or who did not take folate. Type and duration of diabetes, ethnicity, age, BMI, preconception care, smoking and fetal sex were not associated with congenital anomaly risk. CONCLUSIONS: Peri-conception glycaemia is the most important modifiable risk factor for congenital anomaly in women with diabetes. The association with nephropathy merits further study.

    Background The mortality risk associated with congenital airway anomalies (CAA) in children with congenital heart disease (CHD) is unclear. This study aimed to investigate the factors associated with CAA, and the associated mortality risk, among children with CHD. Methods This nationwide, population-based study evaluated 39,652 children with CHD aged 0–5 years between 2000 and 2011, using the Taiwan National Health Insurance Research Database (NHIRD). We performed descriptive, logistic regression, Kaplan–Meier, and Cox regression analyses of the data. Results Among the children with CHD, 1,591 (4.0%) had concomitant CAA. Children with CHD had an increased likelihood of CAA if they were boys (odds ratio [OR], 1.48; 95% confidence interval [CI], 1.33–1.64), infants (OR, 5.42; 95%CI, 4.06–7.24), or had a congenital musculoskeletal anomaly (OR, 3.19; 95%CI, 2.67–3.81), and were typically identified 0–3 years after CHD diagnosis (OR, 1.33; 95%CI 1.17–1.51). The mortality risk was increased in children with CHD and CAA (crude hazard ratio [HR], 2.05; 95%CI, 1.77–2.37), even after adjusting for confounders (adjusted HR, 1.76; 95%CI, 1.51–2.04). Mortality risk also changed by age and sex (adjusted HR and 95%CI are quoted): neonates, infants, and toddlers and preschool children, 1.67 (1.40–2.00), 1.93 (1.47–2.55), and 4.77 (1.39–16.44), respectively; and boys and girls, 1.62 (1.32–1.98) and 2.01 (1.61–2.50), respectively. Conclusion The mortality risk is significantly increased among children with CHD and comorbid CAA. Clinicians should actively seek CAA during the follow-up of children with CHD. PMID:26334302

    The heterotaxy syndrome is a rare and sporadic disorder. This syndrome presents with situs ambiguus, splenic malformations such as asplenia or polysplenia, and congenital heart disease. Congenital heart diseases associated with this syndrome include a broad variety of manifestations. Patent ductus arteriosus is one of them and percutaneous transcatheter closure can be challenging in the setting of this syndrome. Kommerell's diverticulum is a saccular aneurysmal dilation at the origin of an aberrant subclavian artery, and can be related with other congenital anomalies. However, there is no previous report of Kommerell's diverticulum being found together with patent ductus arteriosus and heterotaxy syndrome.

  15. Uranium and other contaminants in hair from the parents of children with congenital anomalies in Fallujah, Iraq

    PubMed Central

    2011-01-01

    Background Recent reports have drawn attention to increases in congenital birth anomalies and cancer in Fallujah Iraq blamed on teratogenic, genetic and genomic stress thought to result from depleted Uranium contamination following the battles in the town in 2004. Contamination of the parents of the children and of the environment by Uranium and other elements was investigated using Inductively Coupled Plasma Mass Spectrometry. Hair samples from 25 fathers and mothers of children diagnosed with congenital anomalies were analysed for Uranium and 51 other elements. Mean ages of the parents was: fathers 29.6 (SD 6.2); mothers: 27.3 (SD 6.8). For a sub-group of 6 women, long locks of hair were analysed for Uranium along the length of the hair to obtain information about historic exposures. Samples of soil and water were also analysed and Uranium isotope ratios determined. Results Levels of Ca, Mg, Co, Fe, Mn, V, Zn, Sr, Al, Ba, Bi, Ga, Pb, Hg, Pd and U (for mothers only) were significantly higher than published mean levels in an uncontaminated population in Sweden. In high excess were Ca, Mg, Sr, Al, Bi and Hg. Of these only Hg can be considered as a possible cause of congenital anomaly. Mean levels for Uranium were 0.16 ppm (SD: 0.11) range 0.02 to 0.4, higher in mothers (0.18 ppm SD 0.09) than fathers (0.11 ppm; SD 0.13). The highly unusual non-normal Fallujah distribution mean was significantly higher than literature results for a control population Southern Israel (0.062 ppm) and a non-parametric test (Mann Whitney-Wilcoxon) gave p = 0.016 for this comparison of the distribution. Mean levels in Fallujah were also much higher than the mean of measurements reported from Japan, Brazil, Sweden and Slovenia (0.04 ppm SD 0.02). Soil samples show low concentrations with a mean of 0.76 ppm (SD 0.42) and range 0.1-1.5 ppm; (N = 18). However it may be consistent with levels in drinking water (2.28 μgL-1) which had similar levels to water from wells (2.72 μgL-1) and the

    This paper represents an attempt to estimate quantitatively, the detriment associated with spontaneously arising congenital anomalies in man. The system used in the International Classification of Diseases (Chapter XIV, entries 740-759) has been followed to classify the congenital anomalies. Detriment was assessed using estimates of the years of life lost, years of life potentially impaired and years of life actually impaired, as indicators. The data on birth prevalences for the various conditions were derived from several epidemiological surveys carried out in Hungary and from the Hungarian Congenital Malformation Registry. Most of the information on mortality profiles was obtained from the records of the Hungarian Central Statistical Office, Budapest. An overall comparison of the prevalence figures in Hungary with those for the U.S. (this study aimed at complete ascertainment) and for the Canadian province of British Columbia (in this study, ascertainment is believed to be incomplete) showed that, in Hungary, at least certain classes of congenital anomalies, particularly some of the less severe ones, have been under-ascertained. Since detriment estimates are heavily dependent on accurate estimates of birth prevalences, we believe that the estimates of detriment arrived at using the Hungarian data may also be underestimates. In Hungary, the total birth prevalence of all isolated major congenital anomalies is of the order of about 600/10(4). Our calculations show that these congenital anomalies may cause, per 10(4) livebirths, about 4800 years of life loss, about 37000 years of potentially impaired life and about 4500 years of actually impaired life. In these calculations, it has been assumed that the average life-expectancy at live birth for the general population is 70 years. These estimates are considerably higher than those made by Carter for detriment associated with spontaneously arising monogenic disorders.

  17. Congenital scoliosis in non-identical twins: case reports and literature review

    PubMed Central

    Greenwood, Dean; Bogar, William

    2014-01-01

    Congenital scoliosis due to vertebral anomalies may occur in less than 0.1% of the population. Several different theories have been put forth in the literature to account for the etiology of congenital scoliosis and the vertebral anomalies which contribute to its development. The study of scoliosis in twins has contributed to the understanding of causative factors including genetics, environment and in utero events during embryologic development. Case reports of fraternal (non-identical) juvenile male twins with congenital scoliosis associated with differing congenital vertebral anomalies are presented. Both children were asymptomatic at the time of the initial consultation and showed no signs of neurologic compromise. Rapidly progressive, severe genetic scoliosis requires prudent observation and referral to a pediatric orthopedic surgeon to determine appropriate options for care and to screen for potentially life threatening disorders. Chiropractors may be seen as gatekeepers for scoliosis and a thorough understanding of appropriate standards of care is required. PMID:25202158

    2015-03-01

    This study aimed to characterize parents' negative (perceived burden) and positive (perceived personal benefits) perceptions about parenting an infant with a congenital anomaly (CA), and to investigate their role in parenting stress. Forty-three couples (43 mothers and 36 fathers) whose 6-month-old infants had a CA completed several questionnaires: the Impact on Family Scale-Revised, the Positive Contributions Scale, and the Parenting Stress Index-Short Form. The results showed similarities between maternal and paternal perceptions. For mothers, higher levels of burden and lower levels of personal benefits were found to predict higher levels of parenting stress. For fathers, greater burden was associated with higher levels of parenting stress. Some dimensions of personal benefits moderated the relationship between burden and parenting stress, for both genders. Specific strategies targeting negative and positive perceptions should be considered when developing psychological interventions to promote the family's adaptation to the experience of parenting an infant with a CA.

  19. True oblique axis fracture associated with congenital anomalies of the upper cervical spine: Case report of an unusual fracture pattern

    PubMed Central

    Robles, Luis A.

    2017-01-01

    Background: Acute traumatic axis fractures are common cervical spine injuries often caused by road accidents or falls. They are usually classified into three different types, namely, odontoid fractures, Hangman's fractures, and miscellaneous fractures. Congenital malformations of the craniovertebral junction (CVJ), although typically asymptomatic, may result in neural compression or instability, especially following trauma. Here, the authors present an unusual oblique axis fracture occurring in conjunction with several malformations of the upper cervical spine. Case Description: Following a motor vehicle accident, a 25-year-old female's radiographic studies showed an oblique axis fracture involving both the anterior and posterior elements along with an anterior and posterior Klippel–Feil syndrome (KFS) anomaly. Following treatment in a halo vest, the patient maintained alignment, and ultimately the fracture was fused. Conclusions: True oblique fractures of the axis are rare, as in the case presented, and may occasionally occur in conjunction with KFS of the upper cervical spine. PMID:28217386

    Chromosomal abnormalities are a major cause of mental retardation and/or multiple congenital anomalies (MCA/MR). Screening for these chromosomal imbalances has mainly been done by standard karyotyping. The objective of this study was to report standard chromosome analysis and FISH screening of a series of 24 patients with MCA/MR. Structural chromosomal abnormalities were detected in 24 alterations and included 5 deletions, 2 duplications, 6 unbalanced translocations, 3 inversions, 2 insertions, 3 derivative chromosomes, 2 marker chromosomes and 1 isochromosome. We confirm that a high percentage of MCA/MR cases hitherto considered idiopathic is caused by chromosomal imbalances. We conclude that patients with MCA/MR should be routinely karyotyped.

CAKUT also account for the most important cause of chronic kidney disease in childhood. This paper focuses on the role of the primary care paediatrician in the diagnosis, assessment, and follow-up of children with CAKUT, with special emphasis on the associated urinary tract infections, the progression toward chronic renal failure, and the genetic basis.

    Cat eye syndrome is a rare congenital disease characterized by the existence of a supernumerary chromosome derived from chromosome 22, with a variable phenotype comprising anal atresia, coloboma of the iris and preauricular tags or pits. We report a girl with cat eye syndrome, presenting short stature, with growth hormone deficiency due to posterior pituitary ectopia. Short stature is a common feature of this syndrome, and the association with a structural pituitary anomaly has been described, however growth hormone deficiency and the underlying mechanisms are rarely reported. A review on short stature and growth hormone deficiency in cat eye syndrome is conducted.

    Familial glaucoma iridogoniodysplasia (FGI) is a form of open-angle glaucoma in which developmental anomalies of the iris and irido-corneal angle are associated with a juvenile-onset glaucoma transmitted as an autosomal dominant trait. A single large family with this disorder was examined for genetic linkage to microsatellite markers. A peak LOD score of 11.63 at a recombination fraction of 0 was obtained with marker D6S967 mapping to chromosome 6p25. Haplotype analysis places the disease gene in a 6.4-cM interval between the markers D6S1713 and D6S1600. Two novel clinical appearances extend the phenotypic range and provide evidence of variable expressivity. The chromosome 6p25 region is now implicated in FGI, primary congenital glaucoma, and iridogoniodysgenesis anomaly. This may indicate the presence of a common causative gene or, alternatively, a cluster of genes involved in eye development/function. Images Figure 2 PMID:9382099

    Pregnant rats were treated with various inhibitors of mitochondrial oxidative energy metabolism and with lowered oxygen tension, and the embryo fetuses examined for the occurrence of congenital malformations and for changes in enzymatic activities. Treatment with all agents tested resulted in the production of skeletal anomalies. Sodium phenobarbital was the most teratogenic of the drugs tested and produced a high incidence of malformations which included cleft palate, tail anomalies, spinal retroflexion, domed head, and facial hypoplasia. Diphenylhydantoin produced a low incidence of syndactyly and oligodactyly. In addition to its effects on fetal growth and development chloramphenicol appeared to interfere with implantation. Tissue preparations from embryos exposed to sodium phenobarbital and chloramphenicol showed markedly lowered levels of DPNH oxidase activity. Cytochrome oxidase activity was also markedly lowered in the preparations from chloramphenicol-exposed embryos. Enzyme activities in preparations from embryos exposed to malonate and diphenylhydantoin appeared unaffected, although the drugs are strong inhibitors of electron transport in vitro; the lack of apparent effect may be due to the fact that both drugs do not bind to the enzyme preparations and were diluted 100- to 200-fold during preparation and assay of the tissue homogenates.

    Pulmonary agenesis is a very rare condition and many of them are associated with a variety of cardiac and non-cardiac malformations. We report an eight-month old girl with chronic lung infection due to right sided pulmonary agenesis without any associated major cardiac or non-cardiac abnormalities. The case brings in forth the importance of investigating any infant presenting with features of chronic lung infection for any congenital abnormality of the lung including aplasia of the lung. This case also emphasizes that mildness of the attack does not exclude right sided aplasia of the lung.

    In November 1981, a leak of solvents from an underground storage tank was detected at an electronics manufacturing plant in Santa Clara County, California. Solvents (predominantly 1,1,1-trichloroethene, or methyl chloroform) were found in a nearby well which supplied drinking water to the surrounding community. Residents were concerned about a possible relation between adverse reproductive outcomes and consumption of contaminated water. To address this concern, the California Department of Health Services conducted two epidemiologic studies: one of these, reported here, is a county-wide study of cardiac anomalies. This study, which looked at major cardiac anomalies among births throughout Santa Clara County in 1981-1983, found an increased prevalence in the service area of the water company which operated the contaminated well. During the potentially exposed time period (January 1981 through August 1982), 12 babies with major cardiac anomalies were born to residents of this area. This represents an excess of six cases over the number expected based on the prevalence in the remainder of the county (relative risk = 2.2, 95 per cent confidence interval 1.2-4.0). No excess was observed in the unexposed time period (September 1982 through December 1983). However, the temporal distribution of major cardiac cases born during the exposed time period suggests that the solvent leak is an unlikely explanation for this excess.

    Introduction: Congenital trigger thumb is an uncommon anomaly of children. Its management is controversial, ranging from observation to extensive surgical release. We report a case of delayed presentation of bilateral trigger thumb along with a brief review of past literature. Case Report: A six year old girl presented with fixed flexion deformity of interphalangeal joints of both thumbs and Notta’s nodules. It is diagnosed as trigger thumb and release of bilateral A1pulleys is done. But we found another constricting annular pulley just distal to A1. Only after splitting the distal pulley, we could get complete extension of interphalangeal joints. At two years follow-up, the child is free of complications. Conclusion: Splitting of A1 pulley alone may not be sufficient in few cases of trigger thumb which may require distal release too PMID:27298940

    Background Hypothesised associations between in utero exposure to selective serotonin reuptake inhibitors (SSRIs) and congenital anomalies, particularly congenital heart defects (CHD), remain controversial. We investigated the putative teratogenicity of SSRI prescription in the 91 days either side of first day of last menstrual period (LMP). Methods and Findings Three population-based EUROCAT congenital anomaly registries- Norway (2004–2010), Wales (2000–2010) and Funen, Denmark (2000–2010)—were linked to the electronic healthcare databases holding prospectively collected prescription information for all pregnancies in the timeframes available. We included 519,117 deliveries, including foetuses terminated for congenital anomalies, with data covering pregnancy and the preceding quarter, including 462,641 with data covering pregnancy and one year either side. For SSRI exposures 91 days either side of LMP, separately and together, odds ratios with 95% confidence intervals (ORs, 95%CI) for all major anomalies were estimated. We also explored: pausing or discontinuing SSRIs preconception, confounding, high dose regimens, and, in Wales, diagnosis of depression. Results were combined in meta-analyses. SSRI prescription 91 days either side of LMP was associated with increased prevalence of severe congenital heart defects (CHD) (as defined by EUROCAT guide 1.3, 2005) (34/12,962 [0.26%] vs. 865/506,155 [0.17%] OR 1.50, 1.06–2.11), and the composite adverse outcome of 'anomaly or stillbirth' (473/12962, 3.65% vs. 15829/506,155, 3.13%, OR 1.13, 1.03–1.24). The increased prevalence of all major anomalies combined did not reach statistical significance (3.09% [400/12,962] vs. 2.67% [13,536/506,155] OR 1.09, 0.99–1.21). Adjusting for socio-economic status left ORs largely unchanged. The prevalence of anomalies and severe CHD was reduced when SSRI prescriptions were stopped or paused preconception, and increased when >1 prescription was recorded, but differences were

    Congenital heart disease is the most common congenital anomaly, representing an important cause of infant morbidity and mortality. Congenital heart disease represents a group of heart anomalies that include septal defects, valve defects, and outflow tract anomalies. The exact genetic, epigenetic, or environmental basis of congenital heart disease remains poorly understood, although the exact mechanism is likely multifactorial. However, the development of new technologies including copy number variants, single-nucleotide polymorphism, next-generation sequencing are accelerating the detection of genetic causes of heart anomalies. Recent studies suggest a role of small non-coding RNAs, micro RNA, in congenital heart disease. The recently described epigenetic factors have also been found to contribute to cardiac morphogenesis. In this review, we present past and recent genetic discoveries in congenital heart disease.

    Pfeiffer syndrome (OMIM 101600) is an autosomal dominant disorder characterized by craniosynostosis, midface hypoplasia, ocular proptosis and digital malformations. We report on a type II Pfeiffer female infant with craniosynostosis, hydrocephalus, and characteristic craniofacial and digital abnormalities. The patient had a history of airway difficulty. Bronchoscopy at age four months revealed low tracheal stenosis and fibrous cartilaginous rings. She underwent tracheostomy for the treatment of cyanotic episodes. Molecular analysis revealed a de novo missense mutation c.870 G>T (TGG>TGT) in the FGFR2 gene that predicts a substitution of cysteine for tryptophan at the codon 290, (W290C). There is phenotypic heterogeneity of tracheal anomalies due to FGFR2 mutations. A review of the literature shows that Pfeiffer patients with the similar tracheal abnormalities can be caused by different FGFR2 mutations and, likewise, the patients with the same FGFR2 mutation may manifest different kinds of tracheal anomalies. Tracheal anomalies may occur in Pfeiffer patients and cause morbidity and mortality because of airway obstruction. Recognition and detailed evaluation of tracheal anomalies should be included in the early diagnostic workup for severe Pfeiffer patients.

    Adults living with congenital heart disease (CHD) now outnumber children with the disease. Thanks to medical advances over the past 75 years, many of these fatal childhood heart problems have changed to chronic medical conditions. As the population of adults with CHD increases, they will require increasingly complex medical, surgical and catheter-based therapies. In addition, social burdens including education, employment and insurability, which increase the societal costs of adult CHD, are now being recognized for adults living with CHD. This review summarizes the available literature on the economics of adult CHD.

    Coronary artery anomalies (CAAs) may be discovered more often as incidental findings during the normal diagnostic process for other cardiac diseases or less frequently on the basis of manifestations of myocardial ischemia. The cardiovascular professional may be involved in their angiographic diagnosis, functional assessment and eventual endovascular treatment. A complete angiographic definition is mandatory in order to understand the functional effects and plan any intervention in CAAs: computed tomography and magnetic resonance imaging are useful non-invasive tools to detect three-dimensional morphology of the anomalies and its relationships with contiguous cardiac structures, whereas coronary arteriography remains the gold standard for a definitive anatomic picture. A practical idea of the possible functional significance is mandatory for deciding how to manage CAAs: non-invasive stress tests and in particular the invasive pharmacological stress tests with or without intravascular ultrasound monitoring can assess correctly the functional significance of the most CAAs. Finally, the knowledge of the particular endovascular techniques and material is of paramount importance for achieving technical and clinical success. CAAs represent a complex issue, which rarely involve the cardiovascular professional at different levels. A timely practical knowledge of the main issues regarding CAAs is important in the management of such entities. PMID:25678906

    Mounier-Kuhn syndrome or congenital tracheobronchomegaly is a chronic airway condition which for currently unknown reasons mostly affects males. It is commonly overlooked on conventional chest X-rays, and is considered to be rare, but the prevalence might be higher as commonly assumed. The hallmark of it is a dilatation of the main airways which frequently, but not always, causes marked, mainly respiratory, symptoms, and patients usually present with varying degrees of recurrent infections, breathlessness, haemoptysis, dyspnoea. Although at least 200 case reports have been published, there have been only a few attempts to review them, and none in the last 20 years. Due to the lack of clinical trials and wide variability of case-report format, a systematic review was deemed not feasible, therefore PubMed and Medline databases were searched using terms "Mounier-Kuhn syndrome", "tracheobronchomegaly", "tracheomegaly", and "bronchomegaly", without any time restrictions, to summarize currently known facts about the syndrome. To the authors' best knowledge, the result is currently the most comprehensive review of previously published literature about the congenital tracheobronchomegaly, and summarizes what's known about symptoms, prevalence, disease associations, and treatment options for this syndrome.

    Chromosome microarray analysis (CMA) is a sensitive method to identify submicroscopic changes too small to be detected by conventional karyotyping. Due to its high-sensitivity in identifying regions with structural variation and hence the genes involved, it is recommended to be the first-tier genetic test for children with intellectual disabilities, development delay or multiple congenital anomalies, and is routinely available in USA and many countries in Europe. Our lab has started offering this as a clinical test based on the research experience on screening >400 children with developmental delay and multiple congenital anomalies since February 2014. To date, 271 patients have been screened using the Agilent 4×180K CGH + SNP array. Copy number variants (CNVs) ranging in size from 10 kb to 154 Mb were found in 109 patients (40%). Pathogenic and likely pathogenic CNVs were found in 55 (20%). These included 45 with deletions, 8 with duplications and 2 patients with both deletion and duplication. Recurrent microdeletion and microduplication syndromes including the Angelman/Prader-Willi syndrome [5], 1p36 microdeletion [3], Williams syndrome [2], 22q11.2 distal deletion syndrome [2], 16p13.3 microdeletion syndrome [2], Cat Eye syndrome, Cri du Chat syndrome, Miller Decker syndrome, 3q29 microdeletion, 15q24 microdeletion, and 1q43q44 syndrome were among the variants detected in our patients. CNVs of uncertain clinical significance were detected in 54 (20%) individuals: 32 were duplications, 18 were deletions and one with both deletion and duplication. However, due to the high cost of the test, parental testing was not performed and hence, significance of these variants could not be established conclusively. In conclusion, CMA is a powerful tool in identifying pathogenic chromosomal copy number alternations. However, due to the high cost of the test, parental testing for the cases where variants of uncertain significant are found is often not possible. CMA is useful

    The aim of this study is to quantify the prevalence and types of rare chromosome abnormalities (RCAs) in Europe for 2000-2006 inclusive, and to describe prenatal diagnosis rates and pregnancy outcome. Data held by the European Surveillance of Congenital Anomalies database were analysed on all the cases from 16 population-based registries in 11 European countries diagnosed prenatally or before 1 year of age, and delivered between 2000 and 2006. Cases were all unbalanced chromosome abnormalities and included live births, fetal deaths from 20 weeks gestation and terminations of pregnancy for fetal anomaly. There were 10,323 cases with a chromosome abnormality, giving a total birth prevalence rate of 43.8/10,000 births. Of these, 7335 cases had trisomy 21,18 or 13, giving individual prevalence rates of 23.0, 5.9 and 2.3/10,000 births, respectively (53, 13 and 5% of all reported chromosome errors, respectively). In all, 473 cases (5%) had a sex chromosome trisomy, and 778 (8%) had 45,X, giving prevalence rates of 2.0 and 3.3/10,000 births, respectively. There were 1,737 RCA cases (17%), giving a prevalence of 7.4/10,000 births. These included triploidy, other trisomies, marker chromosomes, unbalanced translocations, deletions and duplications. There was a wide variation between the registers in both the overall prenatal diagnosis rate of RCA, an average of 65% (range 5-92%) and the prevalence of RCA (range 2.4-12.9/10,000 births). In all, 49% were liveborn. The data provide the prevalence of families currently requiring specialised genetic counselling services in the perinatal period for these conditions and, for some, long-term care.

    Vascular anomalies, including vascular malformations and tumors, are frequently straightforward to detect; however, accurate diagnosis and appropriate treatment are often challenging. Misdiagnosis of these lesions can lead clinicians in the wrong direction when treating these patients, which can have unfavorable results. This review presents an overview of the classification systems that have been developed for the diagnosis of vascular lesions with a focus on the imaging characteristics. Pictorial examples of each lesion on physical examination, as well as non-invasive and minimally invasive imaging are presented. An overview of the endovascular treatment of these lesions is also given. In some cases, vascular anomalies may be associated with an underlying syndrome and several of the most commonly encountered syndromes are discussed. Understanding of the classification systems, familiarity with the treatment options and knowledge of the associated syndromes are essential for all physicians working with this patient population. The approach to the described entities necessitates an organized multi-disciplinary team effort, with diagnostic imaging playing an increasingly important role in the proper diagnosis and a combined interventional radiologic and surgical treatment method showing promising results.

    Patients with craniofacial anomalies often present to doctors due to their noticeable disfigurement and are routinely assessed by otolaryngologists for hearing evaluation. However, small percentage of craniofacial anomaly patients may present with delayed speech though they may not have initial obvious external deformation. The objective of case series is to identify the congenital inner ear malformation. The series of clinical presentation, physical examination, investigations, treatments and follow-up results were demonstrated followed by the discussion.

    ABSTRACT Despite being documented in medical history from over 2400 years ago, primary congenital glaucoma (PCG), being a disease with low incidence rate, remains a challenge to ophthalmologists. The article provides a broad overview on the pathophysiology and diagnostic approach to PCG with major emphasis on the treatment options of PCG. While reviewing on the well-established treatment options, namely goniotomy, trabeculo-tomy and combined trabeculotomy-trabeculectomy, emphasis has also been made to recent updates on secondary treatments: trabeculectomy, antimetabolites, glaucoma-drainage devices and cyclodestructive procedures. It is, however, important to note that the rarity of PCG places limitations on study design, most studies are, thus, retrospective, nonrandomized and have different definitions of surgical success. Ophthalmologists need to interpret the results with critical thinking and formulate individual treatment plans for each patient. How to cite this article: Yu Chan JY, Choy BNK, Alex LK Ng, Shum JWH.

    The present study aimed to examine parental psychological distress and confidence after an infant's birth, when parenting an infant with a diagnosis of a congenital anomaly, and to understand the role of attachment representations on parental adjustment. Parents of infants with a congenital anomaly (44 couples) and parents of healthy infants (46 couples) completed measures of adult attachment representations and of psychological distress and parental confidence (one month after the infant's birth). Results showed no group differences in psychological distress. Mothers in the clinical group presented lower confidence than mothers in the comparison group, while for fathers the inverse pattern was found, showing their involvement in the caretaking of the infant. Insecure attachment representations predicted parental psychological distress, and a moderator role of group was found only for fathers. These results highlight the role of secure attachment representations as an individual resource in stress-inducing situations.

    In 1985, Mardini and Nyhan described three patients from consanguineous families with unilateral complete/partial lung agenesis, congenital cardiac defects, and ipsilateral thumb anomalies. Although there have been many reports of lung agenesis with other malformations, especially hemifacial microsomia and radial ray anomalies, very few demonstrate this triad of defects. We describe three patients with the Mardini-Nyhan association which may represent a distinct entity, although this remains uncertain at present. A fourth patient is also described, the sister of one of the other patients, with complex congenital cardiac disease and bilateral lung lobation abnormalities. This is the first reported incidence of a possible recurrence within a family and suggests, together with the consanguinity observed by Mardini and Nyhan, that recessive inheritance should be considered in genetic counseling for this disorder.

    Since 1983, several authors have used panels of "sentinel" congenital anomalies that might serve as indicators of the human genome mutation rate. The current study suggests a considerably updated panel, and applies it to public health birth defects registry data to determine the potential number of de novo cases. Data were taken from deliveries in 1999-2009 from the Texas Birth Defects Registry, an active surveillance program. Cases with one of the conditions or syndromes in the panel were identified using codes and text searches. Frequencies and birth prevalence were calculated for the overall panel and subcategories within it. Of the 60 conditions appearing in previous papers on sentinel phenotypes, 21 (35%) were used in the current study along with 27 new phenotypes. We found 1,694 cases. Of those, 1,100 exhibited phenotypes thought to arise de novo in at least 90% of the cases ("all/almost all" subpanel), and 594 considered de novo in roughly 50-90% of cases ("most" subpanel). Chromosomal deletion disorders were present in 523 cases and imprinting disorders in 243. After adjusting for maternal age, occurrence of cases in the total panel, "most" subpanel, and imprinting disorders subpanel were significantly associated with paternal age. Our panel of sentinel phenotypes differs from previous panels due to evolved knowledge of genetic disorders, different approaches with respect to interviewing, and different operational definitions. It is hoped that using an overall panel as well as subpanels may maximize statistical power as well as suggest potential mechanisms.

    Congenital anomalies of the kidney and urinary tract (CAKUT) account for approximately 40% of children with ESRD in the United States. Hitherto, mutations in 23 genes have been described as causing autosomal dominant isolated CAKUT in humans. However, >90% of cases of isolated CAKUT still remain without a molecular diagnosis. Here, we hypothesized that genes mutated in recessive mouse models with the specific CAKUT phenotype of unilateral renal agenesis may also be mutated in humans with isolated CAKUT. We applied next-generation sequencing technology for targeted exon sequencing of 12 recessive murine candidate genes in 574 individuals with isolated CAKUT from 590 families. In 15 of 590 families, we identified recessive mutations in the genes FRAS1, FREM2, GRIP1, FREM1, ITGA8, and GREM1, all of which function in the interaction of the ureteric bud and the metanephric mesenchyme. We show that isolated CAKUT may be caused partially by mutations in recessive genes. Our results also indicate that biallelic missense mutations in the Fraser/MOTA/BNAR spectrum genes cause isolated CAKUT, whereas truncating mutations are found in the multiorgan form of Fraser syndrome. The newly identified recessive biallelic mutations in these six genes represent the molecular cause of isolated CAKUT in 2.5% of the 590 affected families in this study.

    Equine Multiple Congenital Ocular Anomalies (MCOA) syndrome is a heritable eye disorder mainly affecting silver colored horses. Clinically, the disease manifests in two distinct classes depending on the horse genotype. Horses homozygous for the mutant allele present with a wide range of ocular defects, such as iris stromal hypoplasia, abnormal pectinate ligaments, megaloglobus, iridociliary cysts and cataracts. The phenotype of heterozygous horses is less severe and predominantly includes iridociliary cysts, which occasionally extend into the temporal retina. In order to determine the genetic cause of MCOA syndrome we sequenced the entire previously characterized 208 kilobase region on chromosome 6 in ten individuals; five MCOA affected horses from three different breeds, one horse with the intermediate Cyst phenotype and four unaffected controls from two different breeds. This was performed using Illumina TruSeq technology with paired-end reads. Through the systematic exclusion of all polymorphisms barring two SNPs in PMEL, a missense mutation previously reported to be associated with the silver coat colour and a non-conserved intronic SNP, we establish that this gene is responsible for MCOA syndrome. Our finding, together with recent advances that show aberrant protein function due to the coding mutation, suggests that the missense mutation is causative and has pleiotrophic effect, causing both the horse silver coat color and MCOA syndrome.

    The most prevalent structural variations in the human genome are copy number variations (CNVs), which appear predominantly in the subtelomeric regions. Variable sizes of 4p/4q CNVs have been associated with several different psychiatric findings and developmental disability (DD). We analyzed 105 patients with congenital anomalies (CA) and developmental and/or intellectual disabilities (DD/ID) using MLPA subtelomeric specific kits (P036 /P070) and 4 of them using microarrays. We found abnormal subtelomeric CNVs in 15 patients (14.3%), including 8 patients with subtelomeric deletions at 4p/4q (53.3%). Additional genomic changes were observed at 1p36, 2q37.3, 5p15.3, 5q35.3, 8p23.3, 13q11, 14q32.3, 15q11.2, and Xq28/Yq12. This indicates the prevalence of independent deletions at 4p/4q, involving PIGG, TRIML2, and FRG1. Furthermore, we identified 15 genes with changes in copy number that contribute to neurological development and/or function, among them CRMP1, SORCS2, SLC25A4, and HELT. Our results highlight the association of genes with changes in copy number at 4p and 4q subtelomeric regions and the DD phenotype. Cytogenomic characterization of additional cases with distal deletions should help clarifying the role of subtelomeric CNVs in neurological diseases.

    Background A number of transporter proteins are expressed in the placenta, and they facilitate the placental transfer of drugs. The inhibition of P-glycoprotein (P-gp) was previously found to be associated with an increase in the risk of congenital anomalies caused by drug substrates of this transporter. We now explore the role of other placental transporter proteins. Methods A population-based case-referent study was performed using cases with congenital anomalies (N = 5,131) from EUROCAT Northern Netherlands, a registry of congenital anomalies. The referent population (N = 31,055) was selected from the pregnancy IADB.nl, a pharmacy prescription database. Results Ten placental transporters known to have comparable expression levels in the placenta to that of P-gp, were selected in this study. In total, 147 drugs were identified to be substrates, inhibitors or inducers, of these transporters. Fifty-eight of these drugs were used by at least one mother in our cases or referent population, and 28 were used in both. The highest user rate was observed for the substrates of multidrug resistance-associated protein 1, mainly folic acid (6% of cases, 8% of referents), and breast cancer resistance protein, mainly nitrofurantoin (2.3% of cases, 2.9% of referents). In contrast to P-gp, drug interactions involving substrates of these transporters did not have a significant effect on the risk of congenital anomalies. Conclusions Some of the drugs which are substrates or inhibitors of placental transporters were commonly used during pregnancy. No significant effect of transporter inhibition was found on fetal drug exposure, possibly due to a limited number of exposures. PMID:28288183

    Ureteral atresia is a rare disease usually associated with a non-functioning dysplastic kidney. The condition may be unilateral or bilateral; focal, short or long and may involve any part of the ureter. Association with other urinary anomalies is rare. We report the case of a 10-month-old boy with prenatal diagnosis of multicystic right kidney. This suspicion was confirmed after birth by ultrasound and static scintigraphy; a right vesicoureteral reflux (VUR) was recorded at cystography. The boy presented a regular renal function but was hospitalized twice for suspected pyelonephritis between the 8th and the 10th month of life and were recorded occasional mild changes in blood pressure. Antibiotic prophylaxis was administered until surgery. When he was 10-month underwent retroperitoneoscopy to perform a nephroureterectomy finding a complete atresia of the upper third of the ureter with the blind end at the level of the uretero-pelvic-junction. The programmed surgery was performed. By a revision of literature, only few cases of imperforate distal ureter have been described. This condition is associated with a kidney dysplasia. The atresia of the ureter with no signs of infection in the dysplastic kidney may be unknown up to adulthood or throughout one's life. Prognosis usually depends on the severity of the obstruction.

    Congenital temporomandibular joint (TMJ) ankylosis is an uncommon condition that presents itself at or soon after birth in the absence of acquired factors that could have contributed to the ankylosis such as infection and trauma. The experience of managing one such case is reported in light of a review of the literature on this condition. Key management principles include adequate removal of the ankylotic mass, costochondral grafting, and post-op physiotherapy. Most patients reported in the literature with the condition experienced relapse. This echoes our own experience where there was recurrence of the ankylosis. However, after removal of the ankylotic mass, the patient maintains a satisfactory maximal incisal opening (MIO) till the present day. The additional challenges faced in the congenital form in addition to the already complex management of acquired paediatric temporomandibular joint ankylosis are (1) much earlier insult to the TMJ, (2) reduced opportunity for neuromuscular development of the muscles of mastication, and (3) reduced compliance with postoperative physiotherapy programmes due to the younger age of these patients.

    Monitoring newborns for adverse outcomes like stillbirth and major congenital anomalies (MCA) is being carried out in government hospitals since 1995 in and around high-level natural radiation areas, a narrow strip of land on the southwest coast of Kerala, India. Natural deposits of monazite sand containing thorium and its daughter products account for elevated levels of natural radiation. Among 141,540 newborns [140,558 deliveries: 139,589 singleton, 957 twins (6.81 ‰), 11 triplets (0.078 ‰), and one quadruplet] screened, 615 (4.35 ‰) were stillbirth and MCA were seen in 1,370 (9.68 ‰) newborns. Clubfoot (404, 2.85 ‰) was the most frequent MCA followed by hypospadias (152, 2.10 ‰ among male newborns), congenital heart disease (168, 1.19 ‰), cleft lip/palate (149, 1.05 ‰), Down syndrome (104, 0.73 ‰), and neural tube defects (72, 0.51 ‰). Newborns with MCA among stillbirths were about 20-fold higher at 190.24 ‰ (117/615) compared to 8.89 ‰ (1,253/140,925) among live births (P < .001). Logistic regression was carried out to compare stillbirth, overall, and specific MCA among newborns from areas with dose levels of ≤1.5, 1.51-3.0, 3.01-6.0 and >6 mGy/year after controlling for maternal age at birth, gravida, consanguinity, ethnicity, and gender of the baby. Clubfoot showed higher prevalence of 3.26 ‰ at dose level of 1.51-3.0 mGy/year compared to 2.33 ‰ at ≤1.5 mGy/year (OR = 1.39; 95 % CI, 1.12-1.72), without indication of any clear dose-response. Prevalences of stillbirth, overall MCA, and other specific MCA were similar across different dose levels and were relatively lower than that reported elsewhere in India, probably due to better literacy, health awareness, and practices in the study population.

    Imaging of the temporal bone is under continous developement. In the recent decades the technical advances of magnetic resonance imaging and computed tomography have contributed to improved imaging quality in assessment of the temporal bone. Dedicated imaging protocols have been developed and are routinely employed in most institutions. However, imaging interpretation remains challenging, since the temporal bone is an anatomically highly complex region and most diseases of the inner ear occur with low incidence, so that even radiologists experienced in the field may be confronted with such entities for the first time. The current review gives an overview about symptoms and imaging appearance of malformations and acquired lesion of the inner ear.

    Background Chagas disease is caused by the parasite Trypanosoma cruzi and endemic in much of Latin America. With increased globalization and immigration, it is a risk in any country due in part to congenital transmission. The frequency of congenital transmission is unclear. Objective To assess the frequency of congenital transmission of T. cruzi. Search Strategy PubMed, Journals@Ovid Full Text, EMBASE, CINAHL, Fuente Academica and BIREME databases were searched using seven search terms related to Chagas disease or Trypanosoma cruzi and congenital transmission. Selection Criteria The inclusion criteria were the following: Dutch, English, French, Portuguese or Spanish language; case report, case series or observational study; original data on congenital T. cruzi infection in humans; congenital infection rate reported or it could be derived. This systematic review included 13 case reports/series and 51 observational studies. Data Collection and Analysis Two investigators independently collected data on study characteristics, diagnosis and congenital infection rate. The principal summary measure – the congenital transmission rate – is defined as the number of congenitally infected infants divided by the number of infants born to infected mothers. A random effects model was utilized. Main Results The pooled congenital transmission rate was 4.7% (95% confidence interval: 3.9–5.6%). Endemic countries had a higher rate of congenital transmission compared to non-endemic (5.0% vs. 2.7%). Conclusions Congenital transmission of Chagas disease is a global problem. Overall risk of congenital infection in infants born to infected mothers is about 5%. The congenital mode of transmission requires targeted screening to prevent future cases of Chagas disease.

    Recent molecular cytogenetic data have shown that the constitution of complex chromosome rearrangements (CCRs) may be more complicated than previously thought. The complicated nature of these rearrangements challenges the accurate delineation of the chromosomal breakpoints and mechanisms involved. Here, we report a molecular cytogenetic analysis of two patients with congenital anomalies and unbalanced de novo CCRs involving chromosome 17p using high-resolution array-based comparative genomic hybridization (array CGH) and fluorescent in situ hybridization (FISH). In the first patient, a 4-month-old boy with developmental delay, hypotonia, growth retardation, coronal synostosis, mild hypertelorism, and bilateral club feet, we found a duplication of the Charcot-Marie–Tooth disease type 1A and Smith-Magenis syndrome (SMS) chromosome regions, inverted insertion of the Miller-Dieker lissencephaly syndrome region into the SMS region, and two microdeletions including a terminal deletion of 17p. The latter, together with a duplication of 21q22.3-qter detected by array CGH, are likely the unbalanced product of a translocation t(17;21)(p13.3;q22.3). In the second patient, an 8-year-old girl with mental retardation, short stature, microcephaly and mild dysmorphic features, we identified four submicroscopic interspersed 17p duplications. All 17 breakpoints were examined in detail by FISH analysis. We found that four of the breakpoints mapped within known low-copy repeats (LCRs), including LCR17pA, middle SMS-REP/LCR17pB block, and LCR17pC. Our findings suggest that the LCR burden in proximal 17p may have stimulated the formation of these CCRs and, thus, that genome architectural features such as LCRs may have been instrumental in the generation of these CCRs.

    Interkinetic nuclear migration (INM) is a phenomenon in which progenitor cell nuclei migrate along the apico-basal axis of the pseudostratified epithelium, which is characterized by the presence of apical primary cilia, in synchrony with the cell cycle in a manner of apical mitosis. INM is suggested to regulate not only stem/progenitor cell proliferation/differentiation but also organ size and shape. INM has been reported in epithelia of both ectoderm and endoderm origin. We examined whether INM exists in the mesoderm-derived ureteric epithelium. At embryonic day (E) 11.5, E12.5 and E13.5, C57BL/6J mouse dams were injected with 5-bromo-2'-deoxyuridine (BrdU) and embryos were killed 1, 2, 4, 6, 8, 10 and 12 h later. We immunostained transverse sections of the ureter for BrdU, and measured the position of BrdU (+) nuclei in the ureteric epithelia along the apico-basal axis at each time point. We analyzed the distribution patterns of BrdU (+) nuclei in histograms using the multidimensional scaling. Changes in the nucleus distribution patterns suggested nucleus movement characteristic of INM in the ureteric epithelia, and the mode of INM varied throughout the ureter development. While apical primary cilia are related with INM by providing a centrosome for the apical mitosis, congenital anomalies of the kidney and urinary tract (CAKUT) include syndromes linked to primary ciliary dysfunction affecting epithelial tubular organs such as kidney, ureter, and brain. The present study showed that INM exists in the ureteric epithelium and suggests that INM may be related with the CAKUT etiology via primary ciliary protein function.

    Congenital coronary artery anomalies are of major significance in clinical cardiology and cardiac surgery due to their association with myocardial ischaemia and sudden death. Such anomalies are detectable by imaging modalities and, according to various definitions, their prevalence ranges from 0.21 to 5.79%. This consensus document from the Development, Anatomy and Pathology Working Group of the European Society of Cardiology aims to provide: (i) a definition of normality that refers to essential anatomical and embryological features of coronary vessels, based on the integrated analysis of studies of normal and abnormal coronary embryogenesis and pathophysiology; (ii) an animal model-based systematic survey of the molecular and cellular mechanisms that regulate coronary blood vessel development; (iii) an organization of the wide spectrum of coronary artery anomalies, according to a comprehensive anatomical and embryological classification scheme; (iv) current knowledge of the pathophysiological mechanisms underlying symptoms and signs of coronary artery anomalies, with diagnostic and therapeutic implications. This document identifies the mosaic-like embryonic development of the coronary vascular system, as coronary cell types differentiate from multiple cell sources through an intricate network of molecular signals and haemodynamic cues, as the necessary framework for understanding the complex spectrum of coronary artery anomalies observed in human patients.

    Congenital Anomalies of the Kidney and Urinary Tract can be associated with Hirschsprung disease. We report on three children with a similar 16p11.2 microdeletion with a spectrum of clinical anomalies consisting of congenital anomalies of the kidney and urinary tract in two patients (Patients 1 and 2) and Hirschsprung disease in two patients (Patients 1 and 3), leading us to hypothesize that a gene in this region is associated with these phenotypes. Patient 1 presented with left renal agenesis, grade-IV vesicoureteral reflux, and Hirschsprung disease, Patient 2 with left renal agenesis, chronic kidney disease, chronic constipation, seizures, and developmental delay, and Patient 3 with Hirschsprung disease and normal kidneys. Genome-wide microarray analysis demonstrated overlapping microdeletions within 16p11.2. The shortest region of overlap in the three patients contained only eight genes, including the SH2 domain-containing binding protein 1 (SH2B1), an adaptor protein which has been implicated in enhancement of the tyrosine kinase activity of RET, whose role in developmental disease of the kidney and enteric enervation is well established. Our findings suggest that 16p11.2 deletions are associated with abnormalities of renal and enteric development and we hypothesize that deletion of SH2B1 may account for the observed phenotype.

    Congenital cataracts can occur as a non-syndromic isolated ocular disease or as a part of genetic syndromes accompanied by a multi-systemic disease. Approximately 50% of all congenital cataract cases have a heterogeneous genetic basis. Here, we describe three generations of a family with an autosomal dominant inheritance pattern and common complex phenotypes, including bilateral congenital cataracts, short stature, macrocephaly, and minor skeletal anomalies. We did not find any chromosomal aberrations or gene copy number abnormalities using conventional genetic tests; accordingly, we conducted whole-exome sequencing (WES) to identify disease-causing genetic alterations in this family. Based on family WES data, we identified a novel BRD4 missense mutation as a candidate causal variant and performed cell-based experiments by ablation of endogenous BRD4 expression in human lens epithelial cells. The protein expression levels of connexin 43, p62, LC3BII, and p53 differed significantly between control cells and cells in which endogenous BRD4 expression was inhibited. We inferred that a BRD4 missense mutation was the likely disease-causing mutation in this family. Our findings may improve the molecular diagnosis of congenital cataracts and support the use of WES to clarify the genetic basis of complex diseases. PMID:28076398

    Left atrial appendage aneurysm is a very rare heart anomaly. It may be congenital or acquired, secondary to inflammatory or degenerative processes. Most cases are asymptomatic. The prevalence of these lesions in pediatric age has been very rarely reported. As it can cause potentially fatal arrhythmias or thrombus, surgery is required immediately after diagnosis. This study reports the case of a 14-year-old boy with rapidly progressive dyspnea, palpitations, sensation of repetitive dizziness and fainting, in whom congenital left atrial appendage aneurysm was detected. Diagnosis was based on coronary CTA data. The patient was successfully treated with surgical resection of the aneurysm.

    Background & objectives: The role of cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in congenital bilateral absence of vas deferens and unilateral renal agenesis (CBAVD-URA) has been controversial. Here, we report the cases of five Indian males with CBAVD-URA. The objective was to evaluate the presence or absence of CFTR gene mutations and variants in CBAVD-URA. The female partners of these males were also screened for cystic fibrosis (CF) carrier status. Methods: Direct DNA sequencing of CFTR gene was carried out in five Indian infertile males having CBAVD-URA. Female partners (n=5) and healthy controls (n=32) were also screened. Results: Three potential regulatory CFTR gene variants (c.1540A>G, c.2694T>G and c.4521G>A) were detected along with IVS8-5T mutation in three infertile males with CBAVD-URA. Five novel CFTR gene variants (c.621+91A>G, c.2752+106A>T, c.2751+85_88delTA, c.3120+529InsC and c.4375-69C>T), four potential regulatory CFTR gene variants (M470V, T854T, P1290P, Q1463Q) and seven previously reported CFTR gene variants (c.196+12T>C, c.875+40A>G, c.3041-71G>C, c.3271+42A>T, c.3272-93T>C, c.3500-140A>C and c.3601-65C>A) were detected in infertile men having CBAVD and renal anomalies Interpretation & conclusions: Based on our findings, we speculate that CBAVD-URA may also be attributed to CFTR gene mutations and can be considered as CFTR-related disorder (CFTR-RD). The CFTR gene mutation screening may be offered to CBAVD-URA men and their female partners undergoing ICSI. Further studies need to be done in a large sample to confirm the findings. PMID:27488005

  1. Clinical and molecular review of atypical congenital adrenal hyperplasia

    PubMed Central

    2015-01-01

    Congenital adrenal hyperplasia (CAH) is one of the most common inherited metabolic disorders. It comprises a group of autosomal recessive disorders caused by the mutations in the genes encoding for steroidogenic enzymes that involved cortisol synthesis. More than 90% of cases are caused by a defect in the enzyme 21-hydroxylase. Four other enzyme deficiencies (cholesterol side-chain cleavage, 17α-hydroxylase [P450c17], 11β-hydroxylase [P450c11β], 3β-hydroxysteroid dehydrogenase) in the steroid biosynthesis pathway, along with one cholesterol transport protein defect (steroidogenic acute regulatory protein), and one electrontransfer protein (P450 oxidoreductase) account for the remaining cases. The clinical symptoms of the different forms of CAH result from the particular hormones that are deficient and those that are produced in excess. A characteristic feature of CAH is genital ambiguity or disordered sex development, and most variants are associated with glucocorticoid deficiency. However, in the rare forms of CAH other than 21-hydroxylase deficiency so-called "atypical CAH", the clinical and hormonal phenotypes can be more complicated, and are not well recognized. This review will focus on the atypical forms of CAH, including the genetic analyses, and phenotypic correlates. PMID:25883920

    Omphalocele, umbilical cord hernia, and gastroschisis are surgically correctable defects of the abdominal wall. Each of these defects has a distinct embryologic basis that results in a characteristic clinical picture. Twenty-five infants with congenital defects of the abdominal wall were treated at the University of New Mexico Hospital in the past four years. Six infants had omphalocele, one had umbilical cord hernia, and 18 had gastroschisis. Survival among infants who underwent a corrective operation was as follows: omphalocele, 50%; umbilical cord hernia, 100%; and gastroschisis, 82%. Long-term survival for the entire group was 72% (18/25). Gastroschisis, which had a lower incidence of major associated anomalies, had a better prognosis than omphalocele. The mortality of congenital abdominal wall defects was related to presence of severe associated anomalies and to poor clinical condition on admission. Prompt and informed initial care may increase the chance of survival.

    Congenital cataract is a common cause of blindness in children; however, its pathogenesis remains unclear. Genetic factors have been shown to play an important role in the pathogenesis of congenital cataract. The current genetic models of congenital cataract include autosomal dominant, autosomal recessive, and sex-linked inheritance. Sex-linked congenital cataract could be inherited through the X or Y chromosome. Congenital cataract is a symptom associated with several X-linked disorders, including Nance-Horan syndrome, Lowe syndrome, Conradi-Hünermann-Happle syndrome, oculo-facio-cardio-dental syndrome, and Alport syndrome. On the other hand, the mechanism and characteristics of Y-linked congenital cataract remains to be identified. Despite its rarity, sex-linked congenital cataract has been known to seriously affect the quality of life of patients. In this review, we present our current understanding of the genes and loci associated with sex-linked congenital cataract. This could help identify novel approaches for the prevention, early diagnosis, and comprehensive disease treatment.

    Congenital anomalies (CA) are the paradigm example of rare diseases liable to primary prevention actions due to the multifactorial etiology of many of them, involving a number of environmental factors together with genetic predispositions. Yet despite the preventive potential, lack of attention to an integrated preventive strategy has led to the prevalence of CA remaining relatively stable in recent decades. The 2 European projects, EUROCAT and EUROPLAN, have joined efforts to provide the first science-based and comprehensive set of recommendations for the primary prevention of CA in the European Union. The resulting EUROCAT-EUROPLAN 'Recommendations on Policies to Be Considered for the Primary Prevention of Congenital Anomalies in National Plans and Strategies on Rare Diseases' were issued in 2012 and endorsed by EUCERD (European Union Committee of Experts on Rare Diseases) in 2013. The recommendations exploit interdisciplinary expertise encompassing drugs, diet, lifestyles, maternal health status, and the environment. The recommendations include evidence-based actions aimed at reducing risk factors and at increasing protective factors and behaviors at both individual and population level. Moreover, consideration is given to topics specifically related to CA (e.g. folate status, teratogens) as well as of broad public health impact (e.g. obesity, smoking) which call for specific attention to their relevance in the pre- and periconceptional period. The recommendations, reported entirely in this paper, are a comprehensive tool to implement primary prevention into national policies on rare diseases in Europe.

    Nonsense-mediated decay (NMD) is an important process that is best known for degrading transcripts that contain premature stop codons (PTCs) to mitigate their potentially harmful consequences, although its regulatory role encompasses other classes of transcripts as well. Despite the critical role of NMD at the cellular level, our knowledge about the consequences of deficiency of its components at the organismal level is largely limited to model organisms. In this study, we report two consanguineous families in which a similar pattern of congenital anomalies was found to be most likely caused by homozygous loss-of-function mutations in SMG9, encoding an essential component of the SURF complex that generates phospho-UPF1, the single most important step in NMD. By knocking out Smg9 in mice via CRISPR/Cas9, we were able to recapitulate the major features of the SMG9-related multiple congenital anomaly syndrome we observed in humans. Surprisingly, human cells devoid of SMG9 do not appear to have reduction of PTC-containing transcripts but do display global transcriptional dysregulation. We conclude that SMG9 is required for normal human and murine development, most likely through a transcriptional regulatory role, the precise nature of which remains to be determined. PMID:27018474

    This study was aimed to evaluate the situation of congenital hypothyroidism (CH) in Guilan using the screening program and determine the correlation of CH with birth weight, gestational age and seasonality. During 2006 to 2010, in Guilan province, neonatal screening for CH by measurement of serum TSH level was performed in 3-5 days after birth. All neonates with TSH level ≥ 5mu/l were referred to endocrinologists and serum TSH, T3 and T4 were measured. Based on public health data and profiles, total number of newborns, gestational age, route of delivery, birth season and birth weight in all screened neonates was reviewed and for ones with CH, their TSH measurements was also recorded. During 5 years, 119701 neonates were screened and CH was confirmed in 10.8% (221) of the referral cases (prevalence=1:542). No significant statistical difference was seen between gender and birth season among patients with CH and the rest of the population. Interestingly, low birth weight (LBW) (31% vs. 4.9%, P<0.01), postdate delivery (1.4% vs. 0.2%, P<0.01) and macrosomia were more prevalent in CH versus normal population (Odds ratio for post-date delivery was 6.9 and for LBW was 3.2). Rate of normal vaginal delivery (NVD) was significantly higher in neonates with CH compared to normal population (39.2% vs. 29.2%, P=0.01). LBW, postdate delivery and macrosomia are risk factors for CH. No association between sex, birth season or caesarian section delivery was seen.

    The Smith-Magenis syndrome (SMS) is a complex and rare congenital condition that is characterized by minor craniofacial anomalies, short stature, sleep disturbances, behavioral, and neurocognitive abnormalities, as well as variable multisystemic manifestations. Little is reported about spinal deformity associated with this syndrome.This study is to present a case of scoliosis occurring in the setting of SMS and explore the possible mechanisms between the 2 diseases.The patient is a 13-year-old Chinese female with congenital scoliosis and Tetralogy of Fallot, mental retardation, obstructive sleep apnea, hypertrophy of tonsil, conductive hearing loss, and agenesis of the epiglottis. An interphase fluorescent in situ hybridization at chromosome 17p11.2 revealed a heterozygous deletion, confirming a molecular diagnosis of SMS. She underwent a posterior correction at thoracic 1-lumbar 1 (T1-L1) levels, using the Moss-SI spinal system. At 6-month follow-up, the patient was clinically pain free and well balanced. Plain radiographs showed solid spine fusion with no loss of correction.Congenital cardiac disease, immunodeficiency, and severe behavioral problems can affect the surgical outcome following spine fusion and need to be taken into consideration for the surgeon and anesthesiologist. Scoliosis is not uncommon among patients with SMS, and there is a potential association between congenital scoliosis and SMS. The potential mechanisms in the pathogenesis of congenital scoliosis of SMS included retinoic acid-induced 1 (RAI1) microdeletion and RAI1 gene point mutation.

    Turner's syndrome is a genetic disease in which many cardiovascular anomalies have been reported, coarctation of the aorta being the most frequent. The most serious complication that can arise from these abnormalities is aortic dissection. The authors present an unusual case of Turner's syndrome with an aortic sinus aneurysm and severe aortic insufficiency in the absence of coarctation of the aorta. The various cardiovascular anomalies seen in Turner's syndrome, such as coarctation of the aorta, bicuspid aortic valve, aortic dissection, aortic sinus aneurysm and ascending aorta aneurysm, can best be understood on a common basis of congenital structural abnormalities involving the aorta and the aortic valve. The only evidence available for such an abnormality is the presence of cystic medial necrosis in the affected vascular tissues.

    Congenital parenchymal lung malformations have an estimated incidence at 1:25,000-1:35,000 births. We present a case of this rare congenital abnormality in a 38 year-old male, review the current literature with discussion of proposed causes, malignant potential, and management strategies. A 38-year-old white male presented with a 4-day history of chronic stable hemoptysis. Social history was notable for a 50-pack-year active smoking history and remote heavy alcohol consumption. Physical examination was normal. Chest radiograph revealed an ill defined right lower lobe infiltrate. Chest computed tomography demonstrated an irregular, thin-walled, cystic lesion with adjacent nodularity and calcifications. The patient received a right lower lobectomy. Pathologic specimen demonstrated a 10-cm, mostly thin-walled cyst with features suggestive of a congenital cyst adenomatoid malformation and areas of adenocarcinoma (mixed subtype with acinar and bronchioloalveolar patterns). Congenital cyst adenomatoid malformations have recently been renamed as congenital pulmonary airway malformations and are the most common type of congenital parenchymal lung malformations. Individuals typically present with recurrent pulmonary infections, pneumothorax, or hemoptysis. The development is controversial but believed to be a result of arrested development of the fetal bronchial tree during the sixth and seventh week of fetal development. Defects in thyroid transcription factor 1 have also been proposed. With the increasing use and image resolution of ultrasound in modern obstetric practice, congenital pulmonary airway malformations rarely go undetected into adulthood. Management remains controversial; however, most authors agree with early surgical excision.

    Congenital anomalies of the kidney and urinary tract (CAKUT) are 1 of the major factors in young adults needing renal replacement therapy, but there is little extensive assessment of their incidence and risk factors. This study aimed to evaluate trends in the incidence of and risk factors for CAKUT among all births in Taiwan.This population-based case-control study design was conducted using the Taiwan national births registry, which contains detailed information about maternal health and characteristics of newborns, supplied by health professionals. Of 1,603,794 newborns registered between 2004 and 2014, 668 infants were reported to have CAKUT. Newborns without congenital anomalies were matched with CAKUT cases by birth year, month, and Apgar score in a ratio of 5:1. Odds ratio (OR) and 95% confidence interval (CI) for developing CAKUT were calculated using a conditional multivariate logistic regression model.The incidence of CAKUT was approximately 4.2 per 10,000 births. The adjusted ORs for CAKUT in newborns associated with maternal age of 20 to 29 (OR, 2.18; 95% CI, 1.11-4.28), or 30 to 39 (OR, 2.29; 95% CI, 1.17-4.51), maternal gestational diabetes (OR, 2.22, 95% CI, 1.06-4.67), maternal thalassemia/hemochromatosis (OR, 2.67; 95% CI, 1.35-5.27), polyhydramnios or oligohydramnios (OR, 9.16; 95% CI, 5.46-15.37), birth parity >1 (OR, 0.27; 95% CI, 0.15-0.50), having a gestational age <37 weeks (OR, 1.48; 95% CI, 1.23-1.78), and being a boy (OR, 1.83; 95% CI, 1.53-2.19). Infants of mother with gestational diabetes were more likely to have congenital anomalies, small gestational age (<37 weeks) and low birth weight.CAKUT are associated with several maternal health risk factors. As Taiwan has the highest prevalence and incidence rates of end-stage renal disease in the world, these findings strongly support the need to develop professional guidelines for prenatal counseling and management of women at risk of adverse birth outcomes, to prevent kidney disease

    Melanocytic nevi are congenital or acquired benign proliferations of cells of melanocytic origin. Oral congenital melanocytic nevi are rare, and only a few cases have been reported in the literature. The purpose of this study is to present the clinical, histological and immunohistochemical features of an oral congenital melanocytic nevus in a 16-year-old female with an 11-year follow-up and to review the pertinent literature. The reported case is the fifth well-documented case report of oral congenital melanocytic nevus in the English literature and the first with a long period of follow-up, thereby making it an important contribution to the knowledge regarding this uncommon oral mucosa lesion.

    This paper reviews the histopathologic features of vestibular abnormalities in congenital disorders affecting the inner ear, based upon a comprehensive literature survey and a review of cases in our temporal bone collection. The review proceeds in three systematic steps. First, we surveyed associated diseases with the major phenotypic features of congenital abnormalities of the inner ear (including the internal auditory canal and otic capsule). Second, the vestibular anomalies are examined specifically. Finally, the anomalies are discussed from a developmental perspective. Among vestibular anomalies, a hypoplastic endolymphatic duct and sac are observed most frequently. Anomalies of the semicircular canals are also often observed. From embryological and clinical viewpoints, many of these resemble the structural features from fetal stages and appear to be associated with vestibular dysfunction. It is expected that progress in genetic analysis and accumulation of temporal bone specimens with vestibular abnormalities in congenital diseases will provide crucial information not only for pathology of those diseases, but also for genetic factors that are responsible for the specific vestibular abnormalities.

    Children and adolescents with congenital limb deficiencies are visibly and physically different from their peers. They present limitations in activities, depending on the severity of deficiency. Therefore they are at risk for lower participation in social and leisure activities. This might negatively influence the perception on their quality of life. The aim of this narrative review is to describe participation and quality of life in children with congenital limb deficiencies. Participation and quality of life are relatively new concepts. Psychosocial functioning, being closely related to the concept of quality of life, is described as well. A comprehensive review of the literature was conducted on participation, quality of life and psychosocial functioning in children and adolescents with congenital limb deficiencies. The review involved a systematic search using multiple data sources. Fifteen cross-sectional studies were included in this review. The literature to date provides limited knowledge on how children and adolescents with congenital limb deficiencies participate and how they perceive their quality of life. The psychosocial functioning, although described as at risk, appears to be comparable to healthy peers. In conclusion, more research is needed on how children and adolescents with congenital limb deficiencies participate and how they perceive their quality of life. A broader perspective will not only help parents in making the right choices for their children, but can also have implications for health care providers, teachers and agencies funding rehabilitation services.

    Evidence of an association between early pregnancy exposure to selective serotonin reuptake inhibitors (SSRI) and congenital heart defects (CHD) has contributed to recommendations to weigh benefits and risks carefully. The objective of this study was to determine the specificity of association between first trimester exposure to SSRIs and specific CHD and other congenital anomalies (CA) associated with SSRI exposure in the literature (signals). A population-based case-malformed control study was conducted in 12 EUROCAT CA registries covering 2.1 million births 1995-2009 including livebirths, fetal deaths from 20 weeks gestation and terminations of pregnancy for fetal anomaly. Babies/fetuses with specific CHD (n = 12,876) and non-CHD signal CA (n = 13,024), were compared with malformed controls whose diagnosed CA have not been associated with SSRI in the literature (n = 17,083). SSRI exposure in first trimester pregnancy was associated with CHD overall (OR adjusted for registry 1.41, 95% CI 1.07-1.86, fluoxetine adjOR 1.43 95% CI 0.85-2.40, paroxetine adjOR 1.53, 95% CI 0.91-2.58) and with severe CHD (adjOR 1.56, 95% CI 1.02-2.39), particularly Tetralogy of Fallot (adjOR 3.16, 95% CI 1.52-6.58) and Ebstein's anomaly (adjOR 8.23, 95% CI 2.92-23.16). Significant associations with SSRI exposure were also found for ano-rectal atresia/stenosis (adjOR 2.46, 95% CI 1.06-5.68), gastroschisis (adjOR 2.42, 95% CI 1.10-5.29), renal dysplasia (adjOR 3.01, 95% CI 1.61-5.61), and clubfoot (adjOR 2.41, 95% CI 1.59-3.65). These data support a teratogenic effect of SSRIs specific to certain anomalies, but cannot exclude confounding by indication or associated factors.

    We describe perinatal findings in a female fetus with partial trisomy 8q(8q24.1-->8qter) and partial monosomy 15q(15q26.1-->15qter) resulting from a paternal t(8;15) reciprocal translocation. Prenatal sonographic examination showed intra-uterine growth retardation, bilateral ventriculomegaly, cardiomegaly with arrhythmia, anhydramnios, and absent kidney and urinary bladder images. The pregnancy was terminated at 28 weeks of gestation. At birth, the infant manifested typical dysmorphic features of partial trisomy 8q. Necropsy further revealed hydrocephalus, congenital diaphragmatic hernia, ventricular septal defect, a horseshoe kidney with renal hypoplasia, and kyphoscoliosis. Our case shows that the coexistence of partial trisomy 8q24.1-->8qter and partial monosomy 15q26.1-->15qter are more detrimental than either defect alone and can result in a complex of major malformations.

    Here we report for the first time on the diagnostic potential of cardiovascular magnetic resonance (CMR) to delineate the proximal course of an anomalous left circumflex coronary artery (LCX) originating from the right pulmonary artery in an adult patient with no other form of congenital heart disease. The patient was referred to our institution due to exertional chest discomfort. X-Ray coronary angiography showed a normal left anterior descending coronary artery (LAD) and right coronary artery (RCA), while the LCX was filled retrograde by collateral flow through the LAD and the RCA. The origin of the LCX was postulated to be the pulmonary artery, but the exact origin of the anomalous artery could not be depicted on conventional angiograms. CMR provided the unambiguous depiction of the origin of the anomalous LCX from the right pulmonary artery and the delineation of its proximal course in this case of a very rare coronary anomaly in adults.

    In many low-and middle-income countries, birth defects are not considered a public health priority and are perceived by the medical community as rare, unpreventable events. In this context, a registry of birth defects should address not only the collection, analysis, and dissemination of information but also contribute to local interventions like prevention, diagnosis, and treatment. We describe the National Registry of Congenital Anomalies of Argentina (RENAC) in terms of case definition, data collection, quality assurance, and data sending, coding, analysis, and information dissemination and we present the strategies used to ensure its sustainability. We emphasize strategies for motivating the people collecting data, such as training activities, participation in research projects, returning the processed data, making useful clinical information available, giving non-monetary rewards, and linking cases to genetic services.

    Angiotensin type 2 receptor gene null mutant mice display congenital anomalies of the kidney and urinary tract (CAKUT). Various features of mouse CAKUT impressively mimic human CAKUT. Studies of the human type 2 receptor (AGTR2) gene in two independent cohorts found that a significant association exists between CAKUT and a nucleotide transition within the lariat branchpoint motif of intron 1, which perturbs AGTR2 mRNA splicing efficiency. AGTR2, therefore, has a significant ontogenic role for the kidney and urinary tract system. Studies revealed that the establishment of CAKUT is preceded by delayed apoptosis of undifferentiated mesenchymal cells surrounding the urinary tract during key ontogenic events, from the ureteral budding to the expansive growth of the kidney and ureter.

    We describe the case of an 83-year-old asymptomatic man followed in our centre. Transoesophageal echocardiography disclosed congenitally corrected transposition of great arteries (CCTGA) with no associated anomalies and only mild aortic regurgitation. Cardiac MR confirmed the diagnosis and revealed preserved systemic ventricle systolic function with a normal perfusional pathway. This report is a demonstration that CCTGA without associated anomalies can reach older life in an asymptomatic condition. This is the oldest asymptomatic living patient with CCTGA ever described.

    Hemifacial hyperplasia is a rare congenital malformation characterized by noticeable unilateral excess development of hard and soft tissues of the face. Asymmetry in Congenital Hemifacial Hyperplasia (CHH) is usually evident at birth and accentuated at the age of puberty. The affected side grows exponentially as compared to the unaffected side. Multiple tissue involvement has resulted due to etiological heterogeneity like heredity, chromosomal abnormalities, altered intrauterine environment, and endocrine dysfunctions. As this lesion is rarely seen in our routine clinical practice, we present a case of hemifacial hyperplasia with reported orofacial features that supplement existing clinical knowledge. This paper also adds knowledge to the readers regarding detailed investigation procedures which has complemented our diagnosis. Further emphasis has been placed on periodic approach to its diagnosis and multidisciplinary management following correct diagnosis.

    Background Array-CGH is considered as the first-tier investigation used to identify copy number variations. Right now, there is no available data about the genetic etiology of patients with development delay/intellectual disability and congenital malformation in East Africa. Methods Array comparative genomic hybridization was performed in 50 Rwandan patients with development delay/intellectual disability and multiple congenital abnormalities, using the Agilent’s 180 K microarray platform. Results Fourteen patients (28%) had a global development delay whereas 36 (72%) patients presented intellectual disability. All patients presented multiple congenital abnormalities. Clinically significant copy number variations were found in 13 patients (26%). Size of CNVs ranged from 0,9 Mb to 34 Mb. Six patients had CNVs associated with known syndromes, whereas 7 patients presented rare genomic imbalances. Conclusion This study showed that CNVs are present in African population and show the importance to implement genetic testing in East-African countries. PMID:25016475

    This paper reports a detailed follow up of 156 patients with structural upper and lower limb anomalies, obtained from the Edinburgh Register of the Newborn (a registration of 52,029 consecutive births between 1964 and 1968). At the time of this survey the patients were between 4 and 9 years of age. The Register had noted probably 96% of all children born with limb defects in Edinburgh between 1964 and 1968. It was found that the diagnosis was completely accurate in only 26% of cases, and partially so in a further 42%. The frequency of each anomaly has been noted, subdivided into isolated anomalies; those that occurred with other limb anomalies, and those that formed part of a syndrome. Syndactyly of toes, post-axial polydactyly of the fingers, polysyndactyly, and brachydactyly were found to have a genetic basis. All `absence' defects, pre-axial polydactyly, and multiple limb deformities appeared to be sporadic. Amongst the sporadic group, the main aetiological factors noted were an excess of maternal toxaemia of pregnancy and of illegitimate children, when compared with the Register Control Data.

    A few studies have suggested an association between maternal exposure to ambient air pollution from vehicular traffic and risk of congenital anomalies in the offspring, but epidemiologic evidence is neither strong nor entirely consistent. In a population-based case-control study in a Northern Italy community encompassing 228 cases of birth defects and 228 referent newborns, we investigated if maternal exposure to PM10 and benzene from vehicular traffic during early pregnancy, as estimated through a dispersion model, was associated with excess teratogenic risk. In conditional logistic regression analysis, and with adjustment for the other pollutant, we found that higher exposure to PM10 but not benzene was associated with increased risk of birth defects overall. Anomaly categories showing the strongest dose-response relation with PM10 exposure were musculoskeletal and chromosomal abnormalities but not cardiovascular defects, with Down syndrome being among the specific abnormalities showing the strongest association, though risk estimates particularly for the less frequent defects were statistically very unstable. Further adjustment in the regression model for potential confounders did not considerably alter the results. All the associations were stronger for average levels of PM10 than for their maximal level. Findings of this study give some support for an excess teratogenic risk following maternal exposure during pregnancy to PM10, but not benzene. Such association appears to be limited to some birth defect categories.

    OBJECTIVE Congenital hydrocephalus (CH) is one of the most frequent CNS congenital malformations, representing an entity with serious pathological consequences. Although several studies have previously assessed child-related risk factors associated with CH development, there is a gap of knowledge on maternal environmental risk factors related to CH. The authors have systematically assessed extrinsic factors in the maternal environment that potentially confer an increased risk of CH development. METHODS The Cochrane Library, MEDLINE, and EMBASE were systematically searched for works published between 1966 and December 2015 to identify all relevant articles published in English. Only studies that investigated environmental risk factors concerning the mother-either during gestation or pregestationally-were included. RESULTS In total, 13 studies (5 cohorts, 3 case series, 3 case-control studies, 1 meta-analysis, and 1 case report) meeting the inclusion criteria were identified. Maternal medication or alcohol use during gestation; lifestyle modifiable maternal pathologies such as obesity, diabetes, or hypertension; lack of prenatal care; and a low socioeconomic status were identified as significant maternal environmental risk factors for CH development. Maternal infections and trauma to the mother during pregnancy have also been highlighted as potential mother-related risk factors for CH. CONCLUSIONS Congenital hydrocephalus is an important cause of serious infant health disability that can lead to health inequalities among adults. The present study identified several maternal environmental risk factors for CH, thus yielding important scientific information relevant to prevention of some CH cases. However, further research is warranted to confirm the impact of the identified factors and examine their underlying behavioral and/or biological basis, leading to the generation of suitable prevention strategies.

    Primary congenital glaucoma is the most common type of infantile glaucoma, yet it remains a relatively rare disease. Treatment is principally surgical, and management lasts a lifetime. In the developing world, delayed diagnosis, limited treatment, and inadequate follow-up lead to a heavier burden on the patient and community. We highlight the epidemiology and genetics of the disease, its current management and prognosis, and the limitations facing both providers and patients in the developing world. Further efforts are necessary to provide effective, timely screening of children and allocate adequate resources to allow health care workers to reduce the rate of avoidable blindness in developing countries.

    2014-11-01

    This review analyses the literature on screening for congenital colour vision deficiency in school students, which predominantly uses the Ishihara test. The review was framed with respect to the established Wilson and Jungner criteria for screening programs. These criteria relate to the characteristics of the condition concerned, the performance of the screening test, the existence of treatment options and the performance of screening programs. The literature reviewed suggests that congenital colour vision deficiency has not been shown to increase risk of road traffic crashes and is not a preclusion to driver licensing in most developed countries. The occurrence of congenital colour vision deficiency has been used to limit entry into certain occupations; however, the value of screening school students with regard to occupational preclusion is questionable. Stronger evidence exists indicating no association between congenital colour vision deficiency and level of educational achievement. Studies showing any association between congenital colour vision deficiency and other health and lifestyle impacts were rare. The most commonly used screening test (using Ishihara pseudoisochromatic plates) performs well with respect to detecting red-green colour vision deficiencies. Finally, the only interventions we identified for congenital colour vision deficiency were management ones around the availability of specific tinted lenses and computer programs to aid colour perception in certain tasks. Given this picture, the weight of evidence appears to be in favour of not adopting (or discontinuing) routine colour vision screening programs for school students; however, it may be worthwhile for a career advisor to refer school students to an optometrist or ophthalmologist for colour vision screening, upon expression of interest in an occupation where normal colour vision is either particularly desirable or is a regulatory requirement.

    The dislocation of a shoulder joint in infancy is extremely rare and is usually the result of traumatic birth injuries, a sequel to brachial plexus injury, or a true congenital dislocation of shoulder. With more advanced obstetric care, the incidence of first two types has drastically decreased. We report a case of true congenital dislocation of shoulder, second of its kind, in a child who was delivered by cesarean section thereby negating any influence of trauma. We report the case because of its rarity, and review the available literature on this topic. We also discuss the management options when encountered with such a rare case scenario. PMID:21655006

    The management of congenital scoliosis requires a systematic approach with careful attention to detail. Any fortuitous diagnosis of vertebral anomalies in infancy, even if there is no significant scoliosis at that time on x-ray, requires frequent clinical and radiographic follow-up to detect progression. The presence of associated anomalies of the spinal cord, the kidneys and the heart should be evaluated by MRI, renal ultrasound or IVP, with cardiology evaluation as indicated. Curve progression or severe vertebral anomalies known to cause curve progression require immediate treatment to prevent deformity. Significant thoracic deformity, especially in a patient with thoracic insufficiency syndrome, is best treated with expansion thoracoplasty. The patient with congenital scoliosis requires a long term commitment to care with frequent orthopaedic follow-up throughout the growing years along with routine pulmonary function assessment once the patient is able to cooperate with testing.

    Congenital cystic lung lesions are rare. Mainly affects the lower respiratory patishta.i are congenital cystic malformation and adematozna bronchopulmonary sequestration (BPS). The pathogenesis of the occurrence of these malformations is not clear but they have a common clinical course. In most cases, the anomaly is asymptomatic and occurs with infections of the lung during the first year of life. Currently congenital lung lesions were classified into five types and is considered by most authors. The anomaly is due to the abnormal proliferation of terminal bronchioles accompanied by inhibition of alveolar development between 7-17 weeks, obstructed airway dysplasia and metaplasia of normal lung tissue. Early diagnosis is vital in making a medical decision on how to treat CCAM. Associated with abnormalities of the urinary tract, cardiovascular system, gastrointestinal atresia, diaphragmatic hernia skeletal abnormalities. In pregnancies in which prenatal lung lesions weighs registered necessary series of ultrasound examinations to track finding and using the Doppler to assess how the blood supply of the fault. The clinical presentation of malformations is respiratory distress, respiratory infection, and dyspnea. The use of CT and MRA allows better visualization of the pulmonary lesions. With its combination with arteriography and bronchoscopy are used to differentiate CCAM and pulmonary sequestration. We present three cases with lung lesions were born in Neonatologia clinic at the University Hospital of Obstetrics and Gynecology "Maternity" Sofia for the period 2010-2012 three cases CCAMs type 1, operated by 5 meters after birth with a good final outcome without complications in the postoperative period and lack of pulmonary symptoms up to 1 year after birth.

    Maternal exposure to ambient pollution has been increasingly linked to the risk of congenital anomalies (CAs) in the fetus and newborns. Recently, a descriptive study in the high environmental risk city of Brindisi (Italy) revealed an increased prevalence of total CAs, especially congenital heart disease (CHD) and ventricular septal defects (VSDs), both at the local level and in comparison with the pool of EUROCAT registries. This paper concerns a population-based case control study to investigate the association between maternal exposure to air pollutants - sulfur dioxide (SO2) and total suspended particulate (TSP) matter - and the risk of CA. Cases were newborns up to 28 days of age, born to mothers resident in Brindisi between 2001 and 2010, and discharged with a diagnosis of CA. Cases and controls were individually matched according to sex, socio-economic status of the census area of residence of the mother, and year of beginning of pregnancy. Up to four controls were extracted for each case. Concentration data from monitoring stations were used to estimate air pollution exposure. Each case and control was assigned pollutant concentration values as mean and 90th percentile of the daily average values during weeks 3-8 of pregnancy. Exposure as both continuous and categorical variables was considered and a conditional logistic regression model was constructed to quantify the odds ratios of exposure to air pollutants and the occurrence of total CAs, CHDs and VSDs. We found exposure to the 90th percentile of SO2 to be associated with CHDs (p for trend =0.01) and VSDs (p for trend <0.05). Findings for TSP were less consistent. In conclusion, in the studied area, maternal exposure to sulfur dioxide increased risk of CHD.

    OBJECTIVES This study evaluated the safety, efficacy and clinical performance of the tissue-engineered ADAPT® bovine pericardial patch (ABPP) in paediatric patients with a range of congenital cardiac anomalies. METHODS In this single-centre, prospective, non-randomized clinical study, paediatric patients underwent surgery for insertion of the ABPP. Primary efficacy measures included early (<30 day) morbidity; incidence of device-related complications; haemodynamic performance derived from echocardiography assessment at 6- and 12-month follow-up and magnetic resonance imaging findings in 10 randomly selected patients at 12 months. Secondary measures included device-handling characteristics; shape and sizing characteristics and perioperative implant complications. The Aristotle complexity scoring system was used to score the complexity level of all surgical procedures. Patients completing the 12-month study were eligible to enter a long-term evaluation study. RESULTS Between April 2008 and September 2009, the ABPP was used in 30 paediatric patients. In the 30-day postoperative period, no graft-related morbidity was observed. In total, there were 5 deaths (2 in the 30-day postoperative period and 3 within the first 6 postoperative months). All deaths were deemed due to comorbid non-graft-related events. Echocardiography assessment at 6 and 12 months revealed intact anatomical and haemodynamically stable repairs without any visible calcification of the patch. Magnetic resonance imaging assessment in 10 patients at 12 months revealed no signs of calcification. Fisher's exact test demonstrated that patients undergoing more complex, higher risk surgical repairs (Aristotle complexity score >8) were significantly more likely to die (P = 0.0055, 58% survival compared with 100% survival for less complex surgical repairs). In 19 patients, echocardiographic data were available at 18–36 months with no evidence of device calcification, infection, thromboembolic events or

    Congenital hemangiomas are rare solitary vascular tumors that do not proliferate after birth. They are characterized as either rapidly involuting congenital hemangiomas (RICHs) or noninvoluting congenital hemangiomas (NICHs) based on their clinical progression. NICHs have no associated complications, but are persistent. RICH, while usually asymptomatic, may ulcerate or bleed early in their presentation, but involute quickly during the first few months of life. Hepatic RICHs are not associated with cutaneous RICHs, but may result in high-output cardiac failure due to arteriovenous or portovenous shunting. In the following review, the clinical characteristics and current management specific to congenital hemangiomas is discussed.

    Global developmental delay (GDD) is defined as a significant delay in two or more developmental domains: gross or fine motor, speech/language, cognitive, social/personal and activities of daily living. Many of these children will go on to be diagnosed with intellectual disability (ID), which is most commonly defined as having an IQ <75 in addition to impairment in adaptive functioning. Cytogenetic studies have been performed in 664 Rwandan pediatric patients presenting GDD/ID and/or multiple congenital abnormalities (MCA). Karyotype analysis was performed in all patients and revealed 260 chromosomal abnormalities. The most frequent chromosomal abnormality was Down syndrome and then Edward syndrome and Patau syndrome. Other identified chromosomal abnormalities included 47,XX,+del(9)(q11), 46,XY,del(13)(q34) and 46,XX,der(22)t(10;22)(p10;p10)mat. In conclusion, our results highlight the high frequency of cytogenetically detectable abnormalities in this series, with implications for the burden on the healthcare. This study demonstrates the importance of cytogenetic analysis in patients with GDD/ID and MCA.

    Rett syndrome (RTT) is a severe neurodevelopmental disorder. Apparently normal at birth, girls with RTT undergo developmental regression and acquire a neurological and behavioural phenotype that has been used to define clinical diagnostic criteria for the disorder. Recently mutations in the methyl-CpG binding protein 2 gene (MECP2), located on Xq28 have been identified in females with RTT. We report a girl whose clinical course was complicated by congenital abnormalities of the respiratory tract and gastrointestinal system. In addition neurological abnormalities were evident in the newborn period. By the age of 3 years she had developed a phenotype very suggestive of RTT, but had not demonstrated deceleration of head growth and the development of expressive language was prevented by the presence of the tracheostomy. The clinical impression of RTT was confirmed by the recent finding of a mutation in the MECP2 gene. This case report highlights the importance of considering the clinical diagnosis of RTT even in the presence of other conditions and emphasises that girls with RTT may not be normal from birth.

    The present study examined psychological adjustment in parents of infants with congenital anomalies (CAs), focusing on the interval from the disclosure of the diagnosis to six months after the infant's birth and considering the effects of the parent's gender and the timing of diagnosis (pre- vs postnatal). Within-group diversity was also examined by identifying distinct patterns of individual adjustment over time. Parents of 43 infants (43 mothers and 36 fathers) with a pre- or postnatal diagnosis of a CA answered questionnaires assessing psychological distress and quality of life one month after the disclosure of the diagnosis and six months after the infant's birth. Results showed a significant reduction in psychological distress and a significant increase in physical quality of life over time, for both parents, regardless of the timing of diagnosis. In all, 57% of parents presented a pattern of recovery from diagnosis to six months post birth and 26.6% presented a pattern of resilience. However, 15.2% of parents showed chronic adjustment difficulties. Findings suggest that most parents tend to adjust to their infant's CA, although some experienced difficulties and should be targeted for specialised counselling. Both members of the couple should be acknowledged, as both experience similar patterns of adjustment.

    This exploratory study examined the role of satisfaction with support from family and friends on the burden and stress of parents of infants with a congenital anomaly (CA). The effects of social support were examined within the couple (actor and partner effects). A total of 36 couples whose six-month-old infant has a CA participated in this study. The parents completed questionnaires regarding satisfaction with support, burden (Impact on Family Scale - Revised), and parenting stress (Parenting Stress Index). The results showed that fathers directly benefited from the support they received from friends in reducing their burden, while mothers only indirectly benefited from it through the father's adjustment. The pattern was different for stress: mothers directly benefited from the support they received from their family in reducing their stress levels, while fathers benefited both directly from the support they received from friends and indirectly from the support that their partners received from family. These results highlight that (1) the different support needs of mothers and fathers (due to their different roles during transition to parenthood) and (2) the diffusion of benefits of social support within the couple should be taken into account when developing strategies to promote support to families of six-month-old infants with a CA.

    Copy number variation (CNV) is of great significance in human evolution and disorders. Through tracing the parent-of-origin of de novo pathogenic CNVs, we are expected to investigate the relative contributions of germline genomic stability on reproductive health. In our study, short tandem repeat (STR) and single nucleotide polymorphism (SNP) were used to determine the parent-of-origin of 87 de novo pathogenic CNVs found in unrelated patients with intellectual disability (ID), developmental delay (DD) and multiple congenital anomalies (MCA). The results shown that there was a significant difference on the distribution of the parent-of-origin for different CNVs types (Chi-square test, p = 4.914 × 10−3). An apparently paternal bias existed in deletion CNVs and a maternal bias in duplication CNVs, indicating that the relative contribution of paternal germline variations is greater than that of maternal to the origin of deletions, and vice versa to the origin of duplications. By analyzing the sequences flanking the breakpoints, we also confirmed that non-allelic homologous recombination (NAHR) served as the major mechanism for the formation of recurrent CNVs whereas non-SDs-based mechanisms played a part in generating rare non-recurrent CNVs and might relate to the paternal germline bias in deletion CNVs.

    We report on a family with 3 males presenting with a not yet described new X-chromosomal syndrome of multiple congenital anomalies and severe mental retardation. Two sisters have (with 3 different partners) 3 severely handicapped sons. In each case, oligohydramnios and intrauterine growth retardation were observed. Delivery was in the 34th, 31st, and 38th gestational week, respectively. Two of the patients had microcephaly (head circumference of the third case at birth is unknown). On physical examination, high and broad forehead, frontal bossing, downslanting palpebral fissures, long philtrum, thin upper lip, high arched palate, and deeply set anteverted ears were seen. One of the boys has microphthalmos and sclerocornea, while his cousin shows atrophy of the optic nerve. All three patients show a severe statomotor and mental retardation, they are most likely deaf and blind, have pathologic EEG, and seizures. Important additional findings are hydronephrosis, renal duplication, vesicorenal reflux, and agenesis of corpus callosum. The karyotype is normal (46,XY). We performed a segregation analysis in the family using more than 20 DNA polymorphisms distributed over the X chromosome. Linkage without recombination was found to KAL, DXS278, and DXS16 in Xp22. Analysis of multiple informative meioses suggested a location of the disease locus distal to DXS207. Recombinants were identified with all other marker loci from Xp22-Xpter.

    Genome-wide array studies are now routinely being used in the evaluation of patients with cognitive disorders (CD) and/or congenital anomalies (CA). Therefore, inevitably each clinician is confronted with the challenging task of the interpretation of copy number variations detected by genome-wide array platforms in a diagnostic setting. Clinical interpretation of autosomal copy number variations is already challenging, but assessment of the clinical relevance of copy number variations of the X-chromosome is even more complex. This study provides an overview of the X-Chromosome copy number variations that we have identified by genome-wide array analysis in a large cohort of 4407 male and female patients. We have made an interpretation of the clinical relevance of each of these copy number variations based on well-defined criteria and previous reports in literature and databases. The prevalence of X-chromosome copy number variations in this cohort was 57/4407 (∼1.3%), of which 15 (0.3%) were interpreted as (likely) pathogenic.

    Contiguous gene or microdeletion syndromes occurring on chromosome 17p include the Smith-Magenis and Miller-Dieker syndromes associated with interstitial deletions of 17p11.2 and 17p13.3, respectively. Other cytogenetically visible interstitial deletions on chromosome 17 are quite rare or unique. We describe a newborn with a novel interstitial deletion of the long arm of chromosome 17 [del(17)(q23.2q24.3)] who died on day of life 17 during a recurrent apneic episode. We have compared our patient`s phenotype and karyotype to two reported patients with deletion 17q with minor clinical overlap. The most striking clinical features of this patient were severe intrauterine growth retardation, widespread skeletal malformations (split sutures, hypoplastic acetabulae and scapulae, vertebral anomalies, and digital hypoplasia), cutis verticis gyrata, dysmorphic facial features, and oropharyngeal malformations (absent uvula and submucous cleft palate). Mild congenital heart disease and anomalous optic nerves were also present. Parental karyotyps were normal. DNA from parents and patient has been collected and cell lines established on both parents. Genes which have been previously mapped to the region that is apparently deleted in this patient include: chorionic somatomammotropin A, growth hormone (normal), acid alpha-glucosidase, apolipoprotein H, and the alpha peptide of type 4 voltage gated sodium channel. As in other clinical cytogenetic syndromes, further descriptions of patients with similar or overlapping rearrangements in this region will be necessary to delineate genotype/phenotype correlations for chromosome 17.

    Purpose To investigate the utility of whole-exome sequencing (WES) to define a molecular diagnosis in patients clinically diagnosed with congenital anomalies of kidney and urinary tract (CAKUT). Methods WES was performed in 62 families with CAKUT. WES data were analyzed for Single Nucleotide Variants (SNVs) in 35 known CAKUT genes, putatively deleterious sequence changes in new candidate genes, and potentially disease-associated copy-number variants (CNVs). Results In approximately 5% of families, pathogenic SNVs were identified in PAX2, HNF1B, and EYA1. Observed phenotypes in these families expand the current understanding about the role of these genes in CAKUT. Four pathogenic CNVs were also identified using two CNV detection tools. In addition, we found one deleterious de novo SNV in FOXP1 among the 62 families with CAKUT. Database of clinical BMGL laboratory was queried and seven additional unrelated individuals with novel de novo SNVs in FOXP1 were identified. Six of these 8 individuals with FOXP1 SNVs, have syndromic urinary tract defects, implicating this gene in urinary tract development. Conclusion We conclude that WES can be used to identify the molecular etiology (SNVs, CNVs) in a subset of individuals with CAKUT. WES can also help identify novel CAKUT genes. PMID:27657687

    Conventional karyotyping detects anomalies in 3-15% of patients with multiple congenital anomalies and mental retardation (MCA/MR). Whole-genome array screening (WGAS) has been consistently suggested as the first choice diagnostic test for this group of patients, but it is very costly for large-scale use in developing countries. We evaluated the use of a combination of Multiplex Ligation-dependent Probe Amplification (MLPA) kits to increase the detection rate of chromosomal abnormalities in MCA/MR patients. We screened 261 MCA/MR patients with two subtelomeric and one microdeletion kits. This would theoretically detect up to 70% of all submicroscopic abnormalities. Additionally we scored the de Vries score for 209 patients in an effort to find a suitable cut-off for MLPA screening. Our results reveal that chromosomal abnormalities were present in 87 (33.3%) patients, but only 57 (21.8%) were considered causative. Karyotyping detected 15 abnormalities (6.9%), while MLPA identified 54 (20.7%). Our combined MLPA screening raised the total detection number of pathogenic imbalances more than three times when compared to conventional karyotyping. We also show that using the de Vries score as a cut-off for this screening would only be suitable under financial restrictions. A decision analytic model was constructed with three possible strategies: karyotype, karyotype + MLPA and karyotype + WGAS. Karyotype + MLPA strategy detected anomalies in 19.8% of cases which account for 76.45% of the expected yield for karyotype + WGAS. Incremental Cost Effectiveness Ratio (ICER) of MLPA is three times lower than that of WGAS, which means that, for the same costs, we have three additional diagnoses with MLPA but only one with WGAS. We list all causative alterations found, including rare findings, such as reciprocal duplications of regions deleted in Sotos and Williams-Beuren syndromes. We also describe imbalances that were considered polymorphisms or rare variants, such as the new SNP

    Uhl's anomaly is a rare congenital heart disease characterized by partial or complete absence of the right ventricular myocardium and high early mortality rates. We describe a case of Uhl's anomaly in a 27-year-old young male patient presenting with portal hypertension and esophageal varices. In this article, we review the literature associated with this condition and highlight a rare presentation of a rare disease. This report adds to our current knowledge of this exceedingly rare disorder.

    Glomerular filtration rate (GFR) and renal volume were evaluated in dogs with confirmed portosystemic vascular anomalies (PSVA) before and after surgical ligation of their PSVA. Pre- and postligation CBC, serum biochemistry, urinalysis, abdominal ultrasonography with measurement of renal volume, and per rectal scintigraphy were performed to document resolution of abnormalities consistent with portosystemic shunting. GFR was estimated by plasma 99mTc-diethylenetriaminepentaacetic acid (99mTc-DTPA) clearance before (n = 21) and after (n = 12) surgical correction of PSVA. Preligation 99mTc-DTPA GFR was increased (median, 5.64 mL/minute/kg; range, 3.53-8.49 mL/minute/kg; reference range, 2.83-4.47 mL/minute/kg) in 81% (17/21) of dogs. Postligation 99mTc-DTPA GFR decreased in all 12 evaluated dogs (median change = -42%; P < .001). Preligation renal volume was above the reference range for the left and right kidneys in 71% (10/14) and 69% (11/16) of dogs evaluated, respectively. Right renal volume decreased significantly (n = 5; median change, -45%; P = .03) after surgical ligation of PSVA. These findings document increased GFR and renal volume in dogs with PSVA, which may explain in part the low blood urea nitrogen and serum creatinine concentrations encountered in these dogs. Knowledge of changes in GFR associated with PSVA ligation may prove helpful in the anesthetic, drug, and dietary management of affected dogs.

    Background Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) represents the most common developmental malformation of the upper digestive tract. It is classified into six subtypes according to the classification of Vogt, depending on anatomical variation of this malformation. Around 50% of the patients with EA/TEF present additional anomalies, which often influence, next to the EA/TEF subtype, the overall prognosis of EA/TEF newborns. Here, we investigated the association of the different EA/TEF subtypes with co-occurring congenital anomalies in EA/TEF patients and demonstrate their implications for postnatal diagnostic workup. Materials and Methods We investigated 333 patients of a large German multicenter study born between 1980 and 2012. After evaluation of all available clinical records, 235 patients were included in our analysis. We compared our results with existing data. Results The highest risk for co-occurring anomalies was seen in patients with most common Vogt 3b (p = 0.024), especially for additional gastrointestinal anomalies (p = 0.04). Co-occurring anomalies of the skin were significantly more common in patients with subtype Vogt 2 (p = 0.024). A significant correlation was observed for an impaired neurodevelopmental outcome and EA/TEF Vogt 3a (p = 0.041). Patients with EA/TEF showed a higher risk to present with any additional congenital anomaly compared with the general population (p < 0.001). Conclusion Our results warrant thorough clinical workup for gastrointestinal anomalies especially in patients with Vogt 3b. Moreover, it might be necessary to focus on a thorough aftercare for neurocognitive development in patients with Vogt 3a. The here presented observations need to be confirmed by future studies.

    Congenital torticollis is characterized by shortening and fibrosis of the sternocleidomastoid (SCM) muscle detected at birth or shortly after birth. This leads to a lateral inclination of the head to the ipsilateral shoulder and chin deviation to the opposite side. When diagnosed early, most cases can be conservatively managed with excellent results. In neglected adult cases, the treatment of this entity is more controversial. A review of the different treatment options in neglected adult cases of congenital torticollis is presented, and a case successfully treated by SCM bipolar release is reported. A 35-year-old woman diagnosed with congenital torticollis was referred to the authors' department. She had been diagnosed at 32 years of age and had been conservatively treated, with no success. Physical examination showed a posterior region of the left SCM muscle hard to palpation, with head tilt to the same side and chin deviation to the right. Bipolar release of the SCM muscle was performed under general anesthesia using the harmonic scalpel. Immobilization with a brace was applied during the first 2 weeks and manual stretching was performed after removal of the brace. Head tilt and movement limitation were resolved, achieving good functional and cosmetic results. Although the best treatment results in congenital torticollis are achieved during the first years of childhood, bipolar release of the SCM muscle followed by postsurgical physical therapy can be effective in neglected adult cases.

    Giant congenital melanocytic nevi (GCMNs) create cosmetic disfigurements and pose risk for malignant transformation. Adult GCMN cases are uncommon because most families opt for surgical treatment during childhood. We review the current literature on GCMN and present an interesting case of an adult with a GCMN encompassing the entire back with painful nodules exhibiting gross involvement of his back musculature, without pathologic evidence of malignancy. Surgical management was deferred in childhood because of parental desires to allow the patient to make his own decision, and treatment in adulthood was pursued on the basis of the significant impairment of the patient's quality of life and self-esteem due to the massive size and deforming nature of the nevus. The treatment strategy used for this young adult male patient involved a massive en bloc excision of the GCMN with partial resection of the latissimus dorsi, followed by a 5-week staged reconstructive process using dermal regenerative matrices and split-thickness skin grafting. Because of the shift in GCMN management from early surgical management to more conservative management, we may see an increase in adult cases of GCMN. Thus, it is critical to better understand the controversy surrounding early versus delayed management of GCMN.

    Objective: Proatlas segementation anomalies are due to defective re-segmentation of the proatlas sclerotome. These anomalies of the craniovertebral junction are rare and have multiple presentations. The aim of this study is to report this author's personal experience in managing five of these patients with different radiological findings necessitating different surgical strategies and to provide a brief review of the relevant literature. Materials and Methods: Five patients, all in the second decade of life were treated between 2010 and 2013. There were three males and two females. All the patients presented with spastic quadriparesis and/or cerebellar signs. Patients underwent plain radiographs, MRI and CT of the craniovertebral junction. CT of the cranioveretebral junction was the key to the diagnosis of this anomaly. Postoperatively, patients were assessed with plain radiographs and CT in all patients and MRI in one. Results: Two patients underwent craniovertebral realignment with occipitocervical fixation, two patients underwent C1-C2 fixation using Goel-Harms technique and one patient underwent craniovertebral realignment with C1-C2 fixation using spacers in the atlanatoaxial joint and foramen magnum decompression. All patients improved during follow up. Conclusions: Proatlas segmentation defects are rare anomalies of the craniovertebral junction. Routine use of thin section CT of the craniovertebral junction and an awareness of this entity and its multivarious presentations are necessary for clinicians dealing with abnormalities of the craniovertebral junction.

    We report on a 7-month-old boy with Micro syndrome who was referred for assessment of mental-motor retardation and reduced vision with cataract. The characteristics of Micro syndrome are mental retardation, microcephaly, congenital cataract, microcornea, microphthalmia, agenesis/hypoplasia of the corpus callosum, and hypogenitalism. The differential diagnosis includes cerebro-oculo-facio-skeletal syndrome (COFS); a syndrome involving cataract, arthrogryposis, microcephaly, and kyphoscoliosis (CAMAK); a syndrome with cataract, microcephaly, failure to thrive, and kyphoscoliosis (CAMFAK); Martsolf syndrome; Neu-Laxova syndrome; Lenz microphthalmia syndrome; and Smith-Lemli-Opitz syndrome. Till date, no renal malformations have been reported in Micro syndrome. Our patient had fusion of the lower poles of the kidneys and his left kidney was ectopic. Ocular findings are the most reliable neonatal diagnostic signs of Micro syndrome. Minör anomalies in Micro syndrome may be subtle and therefore not of significant diagnostic value. Micro syndrome is an autosomal recessive trait. Till date, most reported cases have been in individuals of Muslim origin. In countries with high rates of consanguineous marriage, such as Turkey, it is important that physicians be able to recognize this syndrome. Micro syndrome should be considered in any infant with congenital cataract.

    Individuals with the 18q deletion syndrome are presented with various clinical characteristics, including cardiac anomalies in 24-36% of the reported cases. Nonetheless, genotype-phenotype correlations for cardiac anomalies in the 18q deletion syndrome have rarely been reported. We report on two girls with a terminal 18q deletion, one in whom an Ebstein anomaly and Wolff-Parkinson-White syndrome were detected and the other with multiple valve stenosis and a ventricular septal defect. The genotype and cardiac abnormalities of these girls and 17 other individuals with a de novo 18qter deletion reported in the literature are reviewed. All 19 individuals shared a small overlapping deletion region between 18q22.3q23. The most common cardiac defects detected were pulmonary valve anomalies and atrial septal defects. Ebstein anomaly, a rare cardiac malformation, was diagnosed in two individuals. Additional molecularly based genotype-phenotype studies are needed in order to pinpoint candidate genes within this region that contribute to normal cardiac development. A careful cardiac evaluation consisting of physical examination, ECG and ultrasound examination should be performed in all individuals diagnosed with the 18q deletion syndrome.

    ABSTRACT Introduction: Hypospadias is a congenital abnormality of the penis, in which there is incomplete development of the distal urethra. There are numerous reports showing an increase of prevalence of hypospadias. Association of craniofacial malformations in patients diagnosed with hypospadias is rare. The aim of this study is to describe the association between hypospadias and craniofacial congenital anomalies. Materials and Methods: A retrospective review of the Latin-American collaborative study of congenital malformations (ECLAMC) data was performed between January 1982 and December 2011. We included children diagnosed with associated hypospadias and among them we selected those that were associated with any craniofacial congenital anomaly. Results: Global prevalence was 11.3 per 10.000 newborns. In this population a total of 809 patients with 1117 associated anomalies were identified. On average there were 1.7 anomalies per patient. Facial anomalies were present in 13.2%. The most commonly major facial anomaly associated to hypospadias was cleft lip/palate with 52 cases. We identified that 18% have an association with other anomalies, and found an association between craniofacial anomalies and hypospadias in 0.59 cases/10.000 newborns. Discussion: Hypospadias is the most common congenital anomaly affecting the genitals. Its association with other anomalies is rare. It has been reported that other malformations occur in 29.3% of the cases with hypospadias. The more proximal the meatus, the higher the risk for having another associated anomaly. Conclusion: Associated hypospadias are rare, and it is important to identify the concurrent occurrence of craniofacial anomalies to better treat patients that might need a multidisciplinary approach.

    In 2011, statewide newborn screening programs for critical congenital heart defects began in the United States, and subsequently screening has been implemented widely. In this review, we focus on data reports and collection efforts related to both prenatal diagnosis and newborn screening. Defect-specific, maternal, and geographic factors are associated with variations in prenatal detection, so newborn screening provides a population-wide safety net for early diagnosis. A new web-based repository is collecting information on newborn screening program policies, quality indicators related to screening programs, and specific case-level data on infants with these defects. Birth defects surveillance programs also collect data about critical congenital heart defects, particularly related to diagnostic timing, mortality, and services. Individuals from state programs, federal agencies, and national organizations will be interested in these data to further refine algorithms for screening in normal newborn nurseries, neonatal intensive care settings, and other special populations; and ultimately to evaluate the impact of screening on outcomes.

    Ebstein's anomaly is a complex and heterogeneous form of congenital heart disease characterized by malformation and apical displacement of the tricuspid valve leaflets. Patients may present at any time from the neonatal period to adulthood with symptoms ranging from cardiac failure and cyanosis to paroxysmal arrhythmias. Depending on the timing of presentation, various surgical options are available for the management of symptomatic patients. This review will discuss the perioperative and anesthetic management of patients with Ebstein's anomaly with reference to the more common surgical approaches.

    Congenital cytomegalovirus (CMV) infection is the leading non-genetic cause of sensori-neural hearing loss and neurodevelopmental sequelae. Despite these alarming facts, the general public healthcare system is often not aware of CMV and not enough is done to prevent congenital CMV infection.We describe the clinical and laboratory monitoring of a case with primary CMV infection occurring before the first trimester of gestation. Specific literature review is included in order to point out major goals achieved in the diagnosis and prognosis of congenital CMV infection and the many questions still unanswered. Serological diagnosis of primary CMV infection was performed based on serum-CMV specific-IgM antibodies, combined with low avidity anti-CMV IgG antibodies. The maternal infection was asymptomatic, as it is for most infections in immunocompetent patients. Therefore, disclosing primary infection depended on specific serological tests during the initial period of pregnancy (before weeks 12-16 of gestation). The invasive (amniocentesis) and non-invasive (ultrasonographic examination) prenatal tests, carried out at 21 weeks gestation, revealed a severe CMV infection in a fetus small for gestational age with ventriculomegaly. The presence of overt ultrasound abnormalities combined with high viral load in the amniotic fluid sampled at the appropriate times was highly suggestive of an unfavourable prognosis. The autopsy performed on the fetus confirmed severe disseminated CMV infection with histological brain damage.

    The NESC eras requested by the NASA Jet Propulsion Laboratory (JPL) to conduct an independent review of the Mars Reconnaissance Orbiter (MRO) Thermal/Vacuum (T/V) Anomaly Assessment. Because the anomaly resulted in the surface contamination of the MRO, selected members of the Materials Super Problem Resolution Team (SPRT) and the NASA technical community having technical expertise relative to contamination issues were chosen for the independent review. The consultation consisted of a review of the MRO Project's reported response to the assessment findings, a detailed review of JPL technical assessment final report, and detailed discussions with the JPL assessment team relative to their findings.

    Context Appropriate management of neonates, tested positive for congenital hypothyroidism (CH), in particular, the initial dosage of levothyroxine and the time of initiation of treatment is a critical issue. The aim of this study was to assess all current evidence available on the subject to ascertain the optimal initial dose and optimal initiation time of treatment for children with CH. Evidence Acquisition In this study, all published research related to the initiation treatment dose and the onset time of treatment in congenital hypothyroidism were reviewed. The searched electronic databases included Medline, Science direct, Scopus EMBASE, PsycINFO, Cochrane, BIOSIS and ISI Web of Knowledge. Additional searches included websites of relevant organizations, reference lists of included studies, and issues of major thyroid and pediatrics journals published within the past 35 years. Studies were included if they were written in English and investigated levothyroxine dose or timing of treatment or both, used for the treatment of children with congenital hypothyroidism. Results Two thousand three hundred and seventy-four articles (excluding duplicates) were retrieved from the primary search. After reviewing the titles, abstracts and full-texts of studies, eventually, 22 studies were found that met our inclusion criteria. Amongst these, 17 and 12 evaluated outcomes of different treatment doses and treatment timing, respectively. Overall, the majority of these studies emphasized the initial high dose of levothyroxine and early treatment of newborns with hypothyroidism. There were, however, some studies that disagreed with increasing levothyroxine dose at initiation of treatment. Conclusions Considering the results of this review, apparently there is no difference in opinion regarding the early initiation of treatment, whereas determining the optimal dose of levothyroxine for start of treatment in CH patients still remains a controversial issue, demonstrating the need for

    The association of 46,XY disorder of sex development (DSD) with congenital diaphragmatic hernia (CDH) is rare, but has been previously described with and without other congenital anomalies. Literature review identified five cases of 46,XY DSD associated with CDH and other congenital anomalies. These five cases share characteristics including CDH, 46,XY karyotype with external female appearing or ambiguous genitalia, cardiac anomalies, and decreased life span. The present case had novel features including truncus arteriosus, bifid thymus, gut malrotation, and limb anomalies consisting of rhizomelia and adactyly. With this case report, we present a review of the literature of cases of 46,XY DSD and CDH in association with multiple congenital abnormalities. This case may represent a unique syndrome of 46,XY DSD and diaphragmatic hernia or a more severe presentation of a syndrome represented in the previously reported cases. PMID:25898814

    Advances in our understanding of ovarian cyclicity, pathogenesis of subfertility and/or infertility and reproductive pathology in food animals have frequently entailed examination of abattoir material. Despite the fact that most lesions in ewes are likely to be of relatively minor significance to fertility, results of previous studies suggest that lesions of the female reproductive system may represent a significant source of loss to sheep husbandry. The objective of this paper is to review the pathophysiology, the effects on reproductive efficiency and the key gross and histological diagnostic features of congenital and acquired pathology of ovary and tubular genital organs in ewes.

    Congenital muscular torticollis is a condition in which the sternocleidomastoid muscle is shortened on the involved side, leading to an ipsilateral tilt of the head and a contralateral rotation of the face and chin. Most of these patients present in infancy and are successfully treated with physical therapy. Occasionally, patients present in childhood at which time conservative management is rarely successful. Here we present a child with torticollis who was successfully managed with a unipolar release of the sternocleidomastoid. We then review the epidemiology, proposed etiologies, and various treatment options for torticollis and their rates of success.

    Prenatally diagnosed abnormalities that are associated with death in the newborn period are often referred to as 'lethal malformations'. Yet, for many of the commonly described lethal malformations long-term survival is possible if supportive interventions are provided. In this paper we analyse and review fetal or congenital lethal abnormalities. The designation 'lethal' overlaps with the concept of 'medical futility'. The term is used for a heterogenous group of conditions, and hinders clear communication and counselling. We argue that the term should be avoided, and propose in its place a set of key questions that should be addressed by counselling.

    Congenital mesoblastic nephroma (CMN) is a rare pediatric renal tumor with low malignant potential that most commonly occurs early in infancy. Treatment strategies are based on the few published CMN series, while a significant number of CMN patients have been described in case reports. The aim of this narrative review was to create an up-to-date overview of the literature. Complete surgical removal is curative in most cases. The risk of treatment-related mortality (both surgery- and chemotherapy-related) is relatively high in the first weeks of life, indicating that these young patients deserve special attention with respect to timing and type of treatment.

    Background. As part of regional elimination efforts, rubella-containing vaccines (RCV) have recently been introduced in the Philippines, yet the true burden of rubella and congenital rubella syndrome (CRS) in the country is largely unknown. Objective. To provide baseline information on rubella and CRS prior to routine vaccine introduction in the Philippines. Methods. We conducted a systematic literature review on rubella and CRS in the Philippines, including a cross-sectional study conducted in 2002 among 383 pregnant women attending the obstetric outpatient clinic of the Philippine General Hospital to assess rubella susceptibility of women of childbearing age. Results. 15 locally published and unpublished studies were reviewed. Susceptibility to rubella among women of childbearing age was higher in rural communities. Retrospective reviews revealed congenital heart diseases, cataracts, and hearing impairments to be most common presentations in children of CRS. In the cross-sectional study, 59 (15.4%) of the 383 pregnant women enrolled were seronegative for rubella IgG. Conclusion. Similar to other countries introducing RCV, it was only recently that surveillance for rubella has been established. Previous studies show substantial disabilities due to CRS and a substantial proportion of susceptible women who are at risk for having babies affected with CRS. Establishment of CRS surveillance and enhanced awareness on rubella case detection should be prioritized. PMID:28115948

    Background Despite their widespread use the effects of taking benzodiazepines and non-benzodiazepine hypnotics during pregnancy on the risk of major congenital anomaly (MCA) are uncertain. The objectives were to estimate absolute and relative risks of MCAs in children exposed to specific anxiolytic and hypnotic drugs taken in the first trimester of pregnancy, compared with children of mothers with depression and/or anxiety but not treated with medication and children of mothers without diagnosed mental illness during pregnancy. Methods We identified singleton children born to women aged 15–45 years between 1990 and 2010 from a large United Kingdom primary care database. We calculated absolute risks of MCAs for children with first trimester exposures of different anxiolytic and hypnotic drugs and used logistic regression with a generalised estimating equation to compare risks adjusted for year of childbirth, maternal age, smoking, body mass index, and socioeconomic status. Results Overall MCA prevalence was 2.7% in 1,159 children of mothers prescribed diazepam, 2.9% in 379 children with temazepam, 2.5% in 406 children with zopiclone, and 2.7% in 19,193 children whose mothers had diagnosed depression and/or anxiety but no first trimester drug exposures. When compared with 2.7% in 351,785 children with no diagnosed depression/anxiety nor medication use, the adjusted odds ratios were 1.02 (99% confidence interval 0.63–1.64) for diazepam, 1.07 (0.49–2.37) for temazepam, 0.96 (0.42–2.20) for zopiclone and 1.27 (0.43–3.75) for other anxiolytic/hypnotic drugs and 1.01 (0.90–1.14) for un-medicated depression/anxiety. Risks of system-specific MCAs were generally similar in children exposed and not exposed to such medications. Conclusions We found no evidence for an increase in MCAs in children exposed to benzodiazepines and non-benzodiazepine hypnotics in the first trimester of pregnancy. These findings suggest that prescription of these drugs during early

    Congenital abnormalities of the kidney and urinary tract (CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis (bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number (agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography (US) is typically the first imaging performed as it is easily available, non-invasive and radiation free used both antenatally and postnatally. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management.

    The aim of this study was to examine the prevalence of trisomies 18 and 13 in Europe and the prevalence of associated anomalies. Twenty-five population-based registries in 16 European countries provided data from 2000-2011. Cases included live births, fetal deaths (20+ weeks' gestation), and terminations of pregnancy for fetal anomaly (TOPFAs). The prevalence of associated anomalies was reported in live births. The prevalence of trisomy 18 and trisomy 13 were 4.8 (95%CI: 4.7-5.0) and 1.9 (95%CI: 1.8-2.0) per 10,000 total births. Seventy three percent of cases with trisomy 18 or trisomy 13 resulted in a TOPFA. Amongst 468 live born babies with trisomy 18, 80% (76-83%) had a cardiac anomaly, 21% (17-25%) had a nervous system anomaly, 8% (6-11%) had esophageal atresia and 10% (8-13%) had an orofacial cleft. Amongst 240 Live born babies with trisomy 13, 57% (51-64%) had a cardiac anomaly, 39% (33-46%) had a nervous system anomaly, 30% (24-36%) had an eye anomaly, 44% (37-50%) had polydactyly and 45% (39-52%) had an orofacial cleft. For babies with trisomy 18 boys were less likely to have a cardiac anomaly compared with girls (OR = 0.48 (0.30-0.77) and with trisomy 13 were less likely to have a nervous system anomaly [OR = 0.46 (0.27-0.77)]. Babies with trisomy 18 or trisomy 13 do have a high proportion of associated anomalies with the distribution of anomalies being different in boys and girls.

    In humans, the probability of congenital infection and fetal damage due to Toxoplasma gondii is dependent on the gestation period at which primary infection occurs. Many animal models have been used for vaccine, drug testing, or studies on host or parasite factors that affect transmission or fetal pathology, but few works have directly tested fetal infection and damage rates along gestation. So, the purpose of this work was to perform a systematic review of the literature to determine if there is a model which reflects these changes as they occur in humans. We looked for papers appearing between 1970 and 2014 in major databases like Medline and Scopus, as well as gray literature. From almost 11,000 citations obtained, only 49 papers fulfilled the criteria of having data of all independent variables and at least one dependent datum for control (untreated) groups. Some interesting findings could be extracted. For example, pigs seem resistant and sheep susceptible to congenital infection. Also, oocysts cause more congenitally infected offspring than tissue cysts, bradyzoites or tachyzoites. In spite of these interesting findings, very few results on vertical transmission or fetal damage rates were similar to those described for humans and only for one of the gestation thirds, not all. Moreover, in most designs tissue cysts - with unknown number of bradyzoites - were used, so actual dose could not be established. The meta-analysis could not be performed, mainly because of great heterogeneity in experimental conditions. Nevertheless, results gathered suggest that a model could be designed to represent the increase in vertical transmission and decrease in fetal damage found in humans under natural conditions.

    Cardiovascular malformations are the most common type of birth defect and result in significant mortality worldwide. The etiology for the majority of these anomalies remains unknown but genetic factors are being recognized as playing an increasingly important role. Advances in our molecular understanding of normal heart development have led to the identification of numerous genes necessary for cardiac morphogenesis. This work has aided the discovery of an increasing number of monogenic causes of human cardiovascular malformations. More recently, studies have identified single nucleotide polymorphisms and submicroscopic copy number abnormalities as having a role in the pathogenesis of congenital heart disease. This review discusses these discoveries and summarizes our increasing understanding of the genetic basis of congenital heart disease. PMID:21532774

    Energy imbalance in infants and children with congenital heart disease (CHD) is common and influenced by age, underlying cardiac diagnoses, and presence or absence of congestive heart failure. During the surgical hospitalization period, these children are prone to nutritional deterioration due to stress of surgery, anesthetic/perfusion techniques, and postoperative care. Poor nutrition is associated with increased perioperative morbidity and mortality. This review aims to examine various aspects of nutrition in critically ill children with CHD, including (1) energy expenditure, (2) perioperative factors that contribute to energy metabolism, (3) bedside practices that are potentially able to optimize nutrient delivery, and (4) medium- to long-term impact of energy balance on clinical outcomes. We propose a nutrition algorithm to optimize nutrition of these children in the perioperative period where improvements in nutrition status will likely impact surgical outcomes.

    To have a better understanding of classification of congenital hand anomalies, clinical features and teratogenic mechanisms of congenital absence of digits including ulnar and radial deficiencies, cleft hand, symbrachydactyly and constriction band were reviewed. There seemed to be four different teratogenic mechanisms of congenital absence of digits. Ulnar and radial deficiencies have the same clinical features and the cause of these deficiencies is closely related to a deficit of mesenchymal cells in the limb-bud due to impairment before the formation of the limb-bud. Cleft hand, central polydactyly and osseous syndactyly were induced by the same treatment at the same developmental stage in rats. Roentgenograms of the clinical cases and skeletal changes of the anomalies in rats appear to demonstrate that cleft hand formation proceeds from osseous syndactylies and central polydactylies. The teratogenic mechanism of a cleft hand seemed to be failure of induction of digital rays in the hand plate. The sequence of anomalies from brachysyndactyly, or the atypical cleft hand, to the congenital amputation, can be regarded as equivalent to the category of transverse deficiency that is bony dysplasia of the hand. Congenital constriction ring syndrome appears after the formation of the digital rays.

    Background Developmental venous anomalies (DVAs) are variations of normal transmedullary veins draining white and gray matter. In the vast majority of cases, DVAs are diagnosed incidentally and should be considered as benign entities. In extremely rare circumstances, DVAs may become symptomatic due to mechanical or flow-related etiologies. Thrombosis of the collector vein of a DVA is a rare type of a flow-related complication with only 29 cases reported in the literature, the majority of which are supratentorial. Infratentorial thrombosed DVAs are thus extremely rare and the few cases reported have typically caused symptoms due to venous ischemic infarctions. Summary We report a case of an infratentorial DVA with a thrombosed drainage vein in a patient with nonhemorrhagic, noninfarcted venous congestive edema, which was successfully treated with high-dose glucocorticoids and short-term anticoagulation. We review the pertinent venous anatomy of the posterior fossa as well as the literature of symptomatic infratentorial thrombosed DVAs. Key Message The presented case of an infratentorial thrombosed DVA with cerebellar and pontine venous congestive edema is extremely rare. A working knowledge of posterior fossa venous anatomy and possible pathomechanisms responsible for the rarely symptomatic lesion will aid in the timely and efficacious treatment of such lesions.

    Introduction. Congenital insensitivity to pain and anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV is an extremely rare syndrome. Three clinical findings define the syndrome: insensitivity to pain, impossibility to sweat, and mental retardation. This pathology is caused by a genetic mutation in the NTRK1 gene, which encodes a tyrosine receptor (TrkA) for nerve growth factor (NGF). Methods. The consultation of a child female in our center with CIPA and a tibia fracture in pseudoarthrosis encouraged us to carefully review literature and examine the therapeutic possibilities.

The preventive approach remains the only possible treatment of CIPA. We propose two new important concepts in the therapeutic approach for these patients: (1) early surgical treatment for long bone fractures to prevent pseudoarthrosis and to allow early weight bearing, decreasing the risk of further osteopenia, and (2) bisphosphonates to avoid the progression of osteopenia and to reduce the number of consecutive fractures.

    Introduction. Congenital insensitivity to pain and anhidrosis (CIPA) or hereditary sensory and autonomic neuropathy type IV is an extremely rare syndrome. Three clinical findings define the syndrome: insensitivity to pain, impossibility to sweat, and mental retardation. This pathology is caused by a genetic mutation in the NTRK1 gene, which encodes a tyrosine receptor (TrkA) for nerve growth factor (NGF). Methods. The consultation of a child female in our center with CIPA and a tibia fracture in pseudoarthrosis encouraged us to carefully review literature and examine the therapeutic possibilities. A thorough review of literature published in Pubmed was done about CIPA and other connected medical issues mentioned in the paper. Conclusions. The therapeutic approach of CIPA remains unclear. The preventive approach remains the only possible treatment of CIPA. We propose two new important concepts in the therapeutic approach for these patients: (1) early surgical treatment for long bone fractures to prevent pseudoarthrosis and to allow early weight bearing, decreasing the risk of further osteopenia, and (2) bisphosphonates to avoid the progression of osteopenia and to reduce the number of consecutive fractures.

    We describe a newborn with a novel interstitial deletion of the long arm of chromosome 17 (del(17) (q23.2q24.3)) who died on day of life 17 during a recurrent apneic episode. Her phenotype included severe growth retardation, multiple facial anomalies, maldeveloped oralpharyngeal structures, and digital and widespread skeletal anomalies. This patient`s phenotype was compared to two other reported patients with deletion 17q with minor clinical overlap consistent with a unique deletion. 9 refs., 2 figs.

    Inherited retinal diseases are uncommon pathologies and one of the most harmful causes of childhood and adult blindness. Leber congenital amaurosis (LCA) is the most severe kind of these diseases accounting for approximately 5% of the whole retinal dystrophies and 20% of the children that study on blind schools. Clinical ophthalmologic findings including severe vision loss, nystagmus and ERG abnormalities should be suspected through the first year of life in this group of patients. Phenotypic variability is found when LCA patients have a full ophthalmologic examination. However, a correct diagnosis may be carried out; the determination of ophthalmologic clues as light sensibility, night blindness, fundus pigmentation, among other, join with electroretinographics findings, optical coherence tomography, and new technologies as molecular gene testing may help to reach to a precise diagnosis. Several retinal clinical features in LCA may suggest a genetic or gene particular defect; thus genetic-molecular tools could directly corroborate the clinical diagnosis. Currently, approximately 20 genes have been associated to LCA. In this review, historical perspective, clinical ophthalmological findings, new molecular-genetics technologies, possible phenotype-genotypes correlations, and gene therapy for some LCA genes are described.

    Mucoceles are benign lesions of the oral cavity that develop as a result of retention or extravasation of mucous material from minor salivary glands. Congenital mucoceles are very rare. These lesions in newborns may interfere with breastfeeding and may even compromise respiratory function. A patient with a congenital mucocele diagnosed by prenatal ultrasound screening showing a cystic lesion of the tongue is presented herein. The physical examination, lesion evolution and imaging are described, together with the surgical management, histopathology and two-year follow-up. Early clinical assessment, differential diagnosis and magnetic resonance imaging allow clinicians to diagnose and treat this rare congenital condition with surgery in early infancy.

    Objectives: To determine the prevalence of inner ear anomalies and the frequency of different anomaly types among cochlear implant recipients. Methods: This study included a retrospective chart review of all patients who received cochlear implants between January 2009 and January 2013 in King Abdulaziz University Hospital cochlear implant program in Riyadh, Saudi Arabia. All subjects underwent thin-cut CT of the temporal bone and MRI. The collected data included age, gender, and CT and MRI findings regarding temporal bone anomalies. Patients with any identified congenital inner ear anomalies were included in the study. Results: In total, 316 patients’ cases were reviewed. Inner ear malformations were identified in 24 patients, which represented a prevalence of 7.5%. Among these 24 patients, 8 (33.3%) presented with a large vestibular aqueduct (LVA), 8 (33.3%) semicircular canal (SCC) dysplasia, 7 (29.1%) classical Mondini deformity, and one (4.1%) cochlear hypoplasia. Conclusion: The prevalence of inner ear anomalies among cochlear implant recipients was 7.5%. This result is consistent with findings worldwide. The most common anomalies were LVA and SCC hypoplasia; by contrast, in other regions, the most common anomaly is either the Mondini deformity, or LVA. PMID:27652360

    We describe an infant with congenital vocal cord paralysis born to consanguineous parents. While autosomal dominant and X-linked inheritance have been previously reported in this condition, we conclude that the degree of parental consanguinity in this case strongly suggests autosomal recessive inheritance. Although we cannot exclude X-linked inheritance, evidence from animal studies demonstrates autosomal recessive inheritance and provides a possible molecular basis for congenital vocal cord paralysis. 14 refs., 1 fig.

    A number of developmental anomalies of morphology are there. However, as compared to the more common oral diseases like caries or periodontal problems, they account for a relatively lower number. When present, they may pose various problems of esthetic, function, malocclusion, or possible disposition to other oral problems. Hence, though rare, their timely diagnosis is very vital in proper treatment planning to avoid unseen complications during extractions, endodontic or orthodontic treatment. The present case is of a patient reporting with two very rare developmental anomalies, that is, fusion and root dilaceration, in contralateral sides of the same patient. To the knowledge of the author, reportedly it is the first such case. The terminologies, etiology, and epidemiology of both these anomalies are also discussed. PMID:26604610

    OHVIRA (Obstructed hemivagina and ipsilateral renal anomaly) by acronym and abbreviations in English or Herlyn Werner Wunderlich syndrome is a rare congenital malformation caused by an alteration in the Mullerian ducts and Wolffian Ducts. Which is characterized by a triad: uterus didelphys, obstructed and ipsilateral renal agenesis hemivagina still uncertain etiology. Patients are usually asymptomatic until menarche where the most common clinical presentation is pelvic pain, followed by a vaginal or abdominal mass, normal menstrual periods, infertility, and vaginal discharge rarely appears. The case of a female patient of 15 years, nubile with chronic fetid vaginal discharge, initially diagnosed and treated as pelvic inflammatory disease occurs, however because it is an exceptional condition with the background of the patient, by complementary studies were conducted where pelvic ultrasound revealed pyocolpos and absence of left kidney, uterus didelphys, blind hemivagina by other imaging studies, where we could integrate Herlyn-Werner-Wunderlich syndrome. In conclusion, abnormalities in the development of the Miillerian ducts are difficult to diagnose early, so you must have the embryological knowledge, conduct thorough clinical assessment and detailed picture in whom the coridition is suspected to identify malformations coexisting urinary tract and vaginal defects with the importance of preserving reproductive success through appropriate planning of surgical approach, given that the fertility rate in these patients is comparable to the average.

  1. Zika Virus Infection as a Cause of Congenital Brain Abnormalities and Guillain–Barré Syndrome: Systematic Review

    PubMed Central

    Reveiz, Ludovic; Oladapo, Olufemi T.; Martínez-Vega, Ruth; Haefliger, Anina

    2017-01-01

    Background The World Health Organization (WHO) stated in March 2016 that there was scientific consensus that the mosquito-borne Zika virus was a cause of the neurological disorder Guillain–Barré syndrome (GBS) and of microcephaly and other congenital brain abnormalities based on rapid evidence assessments. Decisions about causality require systematic assessment to guide public health actions. The objectives of this study were to update and reassess the evidence for causality through a rapid and systematic review about links between Zika virus infection and (a) congenital brain abnormalities, including microcephaly, in the foetuses and offspring of pregnant women and (b) GBS in any population, and to describe the process and outcomes of an expert assessment of the evidence about causality. Methods and Findings The study had three linked components. First, in February 2016, we developed a causality framework that defined questions about the relationship between Zika virus infection and each of the two clinical outcomes in ten dimensions: temporality, biological plausibility, strength of association, alternative explanations, cessation, dose–response relationship, animal experiments, analogy, specificity, and consistency. Second, we did a systematic review (protocol number CRD42016036693). We searched multiple online sources up to May 30, 2016 to find studies that directly addressed either outcome and any causality dimension, used methods to expedite study selection, data extraction, and quality assessment, and summarised evidence descriptively. Third, WHO convened a multidisciplinary panel of experts who assessed the review findings and reached consensus statements to update the WHO position on causality. We found 1,091 unique items up to May 30, 2016. For congenital brain abnormalities, including microcephaly, we included 72 items; for eight of ten causality dimensions (all except dose–response relationship and specificity), we found that more than half the

  2. Primary Congenital Lymphedema Complicated by Hydrops Fetalis: A Case Report and Review of the Literature

    2013-01-01

    Introduction. Primary congenital lymphedema is a rare disorder associated with insufficient development of lymphatic vessels. Usually most patients present with lower extremity edema seen sonographically. Rarely primary congenital lymphedema may be associated with severe lymphatic dysfunction resulting in hydrops fetalis. Case. A 27-year-old primigravida with a family history of leg swelling throughout multiple generations was diagnosed early in the third trimester with hydrops fetalis. Delivery was undertaken at 32 weeks for nonreassuring fetal status and the infant expired at approximately 45 minutes of life. Primary congenital lymphedema was confirmed via molecular testing of the vascular endothelial growth factor receptor-3 gene. Discussion. The diagnosis of PCL is suspected prenatally when ultrasound findings coincide with a positive family history of chronic lower limb lymphedema. Isolated PCL is rarely associated with significant complications. Rarely, however, widespread lymphatic dysplasia may occur, possibly resulting in nonimmune hydrops fetalis. PMID:23533860

    Chromosome 10q deletions are rare and phenotypically diverse. Such deletions differ in length and occur in numerous regions on the long arm of chromosome 10, accounting for the wide clinical variability. Commonly reported findings include dysmorphic facial features, microcephaly, developmental delay, and genitourinary abnormalities. Here, we report on a female patient with a novel interstitial 5.54 Mb deletion at 10q24.31-q25.1. This patient had findings in common with a previously reported patient with an overlapping deletion, including renal anomalies and an orofacial cleft, but also demonstrated lobar holoprosencephaly and a Dandy-Walker malformation, features which have not been previously reported with 10q deletions. An analysis of the region deleted in our patient showed numerous genes, such as KAZALD1, PAX2, SEMA4G, ACTRA1, INA, and FGF8, whose putative functions may have played a role in the phenotype seen in our patient.

    Growing evidence has proved that many aspects of our lifestyle and the environment contribute to the development of congenital disease. Congenital spinal deformities are due to anomalous development of the vertebrae including failure of formation and segmentation during embryogenesis. The causes of congenital scoliosis have not been fully identified. A variety of factors are implicated in the development of vertebral abnormalities. Previous studies have demonstrated that both genetics and environmental factors are implicated in the development of vertebral abnormalities. However, no specific cause for congenital scoliosis has been identified. In our review, we focus on the environmental factors for the development of congenital scoliosis. Various maternal exposures during pregnancy including hypoxia, alcohol use, vitamin deficiency, valproic acid, boric acid, and hyperthermia have been observed to be associated with the occurrence of congenital scoliosis. This review describes the major environmental contributors of congenital scoliosis with an emphasis on treatment aspects associated with environmental disposition in congenital scoliosis.

    Congenital megacalycosis is a rare renal disease characterized by calyceal dilatation without pelvic or ureteral obstruction. If not accompanied by nephrolithiasis and urinary tract infection, this disease is completely benign and does not cause renal dysfunction. We present a case of congenital megacalycosis that was diagnosed at the age of 41 (oldest case in the literature) after admitting with hematuria and acute renal dysfunction. IgA nephropathy was also diagnosed in this patient. Since renal dysfunction is not likely in these patients, if encountered; renal biopsy should be performed although technically difficult to diagnose the cause of this dysfunction.

    Terminal deletion in the short arm of chromosome 1 results in a disorder described as 1p36 deletion syndrome. The resulting phenotype varies among patients including mental retardation, developmental delay, sensorineural hearing loss, seizures, heart defects, and distinct facies. In the present case, we performed array-comparative genomic hybridization in a boy with multiple congenital malformations presenting some features overlapping the 1p36 deletion phenotype for whom chromosomal analysis did not reveal a terminal deletion in 1p. Results showed complex chromosome rearrangements involving the 1p36.33-p35.3 region. While the mechanism of origin of these rearrangements is still unclear, chromothripsis-a single catastrophic event leading to shattering chromosomes or chromosome regions and rejoining of the segments-has been described to occur in a fraction of cancers. The presence of at least 12 clustered breaks at 1p and apparent lack of mosaicism in the present case suggests that a single event like chromothripsis occurred. This finding suggests that chromothripsis is responsible for some constitutive complex chromosome rearrangements.

    Neuroblastoma is the most frequent extra cranial solid tumor in infants and children. Genetic predisposition to neuroblastoma has been suspected previously due to familial cases of sporadic NB and predisposition to NB in several syndromes. Here, we report on a de novo 14q23.1-q23.3 microdeletion in a male presenting with a neuroblastoma diagnosed at 9 months, and spherocytosis, congenital heart defect, cryptorchidism, hypoplasia of corpus callosum, epilepsy, and developmental delay. Myc-associated-factor X (MAX) haploinsufficiency could be regarded as the predisposing factor to NB. Indeed 14q deletion is a recurrent somatic rearrangement in NB and MAX somatic and germline loss of function mutation have recently been described in pheochromocytoma and paraganglioma. However, MAX was expressed in the tumor of the patient we report on and, accordingly, loss of heterozygosity, mutation, or promoter methylation were excluded. In addition, we discuss the potential involvement in the clinical spectrum presented by the patient of five of the deleted genes, namely DAAM1, PLEKHG3, SPTB, AKAP5, and ARID4A.

    The present study deals with karyotpye-phenotype correlations in a six month old child with multiple congenital abnormalities. Cytogenetic analysis revealed mosaicism of a small metacentric supernumerary marker chromosome with a karyotype mos 47,XY+mar[34]/46,XY[31]. Cytogenetic microarray result showed three copies of chromosome 18p (15,400 kb in size). Moreover, 255 kbp intermittent deletion of chromosome 2q13 involving RGPD5, RGPD6, LIMS3, and LIMS3-LOC440895 was also observed. Correlating microarray data with the mosaic karyotype, the marker chromosome was identified as mosaic isochromosome 18p and was found to be 32,600 kbp in size. Baby resembled clinical characteristics of trisomy chromosome 18p, isochromosome 18p and trisomy chromosome 18. The present study suggested that deletion of evolutionarily conserved developmental genes (RGPD5, RGPD and LIMS3) in the 2q13 region might have contributed to more severity in phenotype as compared to so far such reported cases of 18p trisomy's, as these are involved in nuclear-cytoplasm trafficking, signaling for tissue patterning and differentiation.

    A multiple cardiac anomaly in sheep is presented to show how complicated the result of abnormal development can be. The heart of a 12-hour-old sheep was fixed in 8% formaldehyde solution and subsequently dissected by an anatomical method, and the abnormalities were recorded on digital pictures. The abnormal anatomy is described and compared with the simple developmental anomalies. Developmental abnormalities were found in the distal portion of the bulbus, the aortic arches and the interatrial septum. A special type of the double-outlet right ventricle was observed, which was not a real double-outlet ventricle because it occurred in combination with pulmonary atresia. Coarctation of the aorta was seen, the ductus arteriosus was absent, and there were five vessels originating from the aortic arch instead of one vessel seen in normal cases, as a result of the abnormal development of the aortic arches.

    Certain congenital heart anomalies make patients more susceptible to arrhythmia development throughout their lives. This poses the question whether prophylactic arrhythmia surgery should be incorporated into reparative open heart procedures for congenital heart disease. There is currently no consensus on what constitutes a standard prophylactic procedure, owing to the questions that remain regarding lesions to be performed; energy sources to use; proximity of energy source or incisions to coronary arteries, sinoatrial node, atrioventricular node; circumstances for right atrial, left atrial, or biatrial appendectomy; and whether to perform a right, left, or biatrial maze procedure. These considerations are important because prophylactic arrhythmia procedures are performed without knowing if the patient will actually develop an arrhythmia in his or her lifetime. By reviewing and summarizing the literature, congenital heart disease patients who are at risk for developing atrial arrhythmias can be identified and lesion sets can be suggested in an effort to standardize experimental protocols for prophylactic arrhythmia surgery.

    The pattern of anatomical organization of the thoraco-abdominal visceral and vascular structures which is not the expected normal arrangement, is called as situs ambiguous or heterotaxy syndrome. Patients with heterotaxy syndrome exhibit a wide spectrum of anatomical variations involving thoraco-abdominal structures. We present here an incidental finding of heterotaxy syndrome associated with unique vascular anomalies in a 35 year old male patient evaluated initially for nephrolithiasis by ultrasonography, and intravenous pyelography. Further evaluation by multidetector row computed tomography showed bilateral bilobed lungs with hyparterial bronchi, cardiac apex to the left, five branches from left-sided aortic arch with retroesophageal right subclavian artery, interrupted inferior vena cava with azygos continuation, left renal vein continuing as hemiazygos vein and replaced common hepatic artery arising from the superior mesenteric artery. Other vascular anomalies include right internal iliac vein joining the left common iliac vein and precaval course of the single main right renal artery. Anomalies involving abdominal organs include right-sided stomach, midline liver, multiple splenules (polysplenia) in right upper quadrant of abdomen, short truncated pancreas, intestinal malrotation, inversion of superior mesenteric vessels and a preduodenal portal vein. To the best of our knowledge this is the first report of association of left renal vein continuing as hemiazygos vein, precaval right renal artery and anomalous branching pattern of aortic arch with heterotaxy syndrome.

    Neonatal chylothorax results from the accumulation of chyle in the pleural space and may be either congenital or an acquired condition. Congenital chylothorax is most likely due to abnormal development or obstruction of the lymphatic system. It is often associated with hydrops fetalis. It can be idiopathic or may be associated with various chromosomal anomalies including Trisomy 21, Turner syndrome, Noonan syndrome, and other genetic abnormalities. Congenital pulmonary lymphangiectasia and generalized lymphangiomatosis have also been reported to be associated with congenital chylothorax. Several case reports indicate that congenital chylothorax can recur in subsequent offspring, suggesting a possible underlying genetic etiology. It is important to identify infants with chylothorax, as there are specific issues that need to be addressed in the management of these patients. We present a case of newborn with trysomy 21 (trisomy 21 was diagnosed antenatally by amniocentesis with support of Association "Perinatology"), who developed moderate Respiratory Distress Syndrome, chest X-ray and US reveal pleural effusion on right side rapid intervention was made before deterioration, requiring intensive life-saving measures. In the neonate, chylous effusion is not a common cause of pleural effusions. It is characterized as an exudate because of the high protein and lipid content once the infant is fed. The fluid will be clear/yellow to slightly cloudy in the unfed state and will quickly become milky following feeding, as chylomicrons appear in the fluid. Lymphocytes predominate in the differential cell count of chyle. The volume of fluid output can be high, and management can be challenging. We review the common manifestations of congenital chylotoraxes and emphasize the importance of early diagnosis and intervention in preventing devastating outcomes from this condition.

    Abnormalities of the posterior arch, including congenitally absent cervical pedicle and cervical spondylolysis, are rare entities that are usually found incidentally on neck radiographs. It is important to recognize these characteristic radiological features because their radiographic appearance may cause them to be confused with more serious entities such as fractures, locked facets, and tumor-induced bony erosions. Also, it is important to distinguish these abnormalities from similar pathologies to prevent the use of inappropriate treatment. We report the relevant clinical and radiological findings seen in three cases of posterior arch defect after trauma with review of pertinent literature. PMID:21082064

    With advances in pediatric cardiology and cardiac surgery, the population of adults with congenital heart disease (CHD) has increased. In the current era, there are more adults with CHD than children. This population has many unique issues and needs. Since the 2001 Canadian Cardiovascular Society Consensus Conference report on the management of adults with CHD, there have been significant advances in the field of adult CHD. Therefore, new clinical guidelines have been written by Canadian adult CHD physicians in collaboration with an international panel of experts in the field. Part II of the guidelines includes recommendations for the care of patients with left ventricular outflow tract obstruction and bicuspid aortic valve disease, coarctation of the aorta, right ventricular outflow tract obstruction, tetralogy of Fallot, Ebstein anomaly and Marfan’s syndrome. Topics addressed include genetics, clinical outcomes, recommended diagnostic workup, surgical and interventional options, treatment of arrhythmias, assessment of pregnancy risk and follow-up requirements. The complete document consists of four manuscripts that are published online in the present issue of The Canadian Journal of Cardiology.

    A congenital granular cell tumour is rare, and presents in newborns as a mass arising from the alveolus. While its pathogenesis is unclear, it has no malignant potential and may, occasionally, spontaneously regress postpartum. Successful treatment usually consists of conservative simple excision.

    The purpose of this study was to characterize a large group of infants with complete DiGeorge anomaly and to evaluate the ability of thymus transplantation to reconstitute immune function in these infants. DiGeorge anomaly is characterized by varying defects of the heart, thymus, and parathyroid glands. Complete DiGeorge anomaly refers to the subgroup that is athymic (< 1%). The characteristics of 54 subjects at presentation and results from 44 consecutive thymus transplantations are reported. Remarkably, only 52% had 22q11 hemizygosity and only 57% had congenital heart disease requiring surgery. Thirty-one percent developed an atypical phenotype with rash and lymphadenopathy. To date, 33 of 44 subjects who received a transplant survive (75%) with post-transplantation follow-up as long as 13 years. All deaths occurred within 12 months of transplantation. All 25 subjects who were tested 1 year after transplantation had developed polyclonal T-cell repertoires and proliferative responses to mitogens. Adverse events developing after transplantation included hypothyroidism in 5 subjects and enteritis in 1 subject. In summary, diagnosis of complete DiGeorge anomaly is challenging because of the variability of presentation. Thymus transplantation was well tolerated and resulted in stable immunoreconstitution in these infants.

    The region of South America is emphasized in the present consideration of the Southern Oscillation (SO) oceanic and atmospheric circulation changes. The persistence of climate anomalies associated with El Nino-SO events is due to strong atmosphere-ocean coupling. Once initiated, the SO follows a certain sequence of events with clearly defined effects on tropical and subtropical rainfall. Excessive rainfall related to the SO in the central and eastern Pacific, Peru, Ecuador, and southern Brazil, are complemented by drought in Australia, Indonesia, India, West Africa, and northeast Brazil. El Nino-SO events are also associated with dramatic changes in the tropospheric flow pattern over a broad area of both hemispheres.

    Congenital diaphragmatic hernia (CDH) is a severe birth defect characterized by a defect in the diaphragm with pulmonary hypoplasia and postnatal pulmonary hypertension. Approximately 50% of CDH cases are associated with other non-pulmonary congenital anomalies (so called non-isolated CDH) and in 5-10% of cases there is a chromosomal etiology. The majority of CDH cases are detected prenatally. In some cases prenatal chromosome analysis reveals a causative chromosomal anomaly, most often aneuploidy. Deletion of 15q26 is the most frequently described structural chromosomal aberration in patients with non-isolated CDH. In this paper we report on two patients with a deletion of 15q26 and phenotypes similar to other patients with CDH caused by 15q26 deletions. This phenotype consists of intra-uterine growth retardation, left-sided CDH, cardiac anomalies and characteristic facial features, similar to those seen in Fryns syndrome. We propose that when this combination of birth defects is identified, either pre- or postnatally, further investigations to confirm or exclude a deletion of 15q26 are indicated, since the diagnosis of this deletion will have major consequences for the prognosis and, therefore, can affect decision making.

    Sickle cell anemia and thalassemia are hemoglobinopathies rarely encountered in the United States. Compounded with congenital heart disease, patients with sickle cell disease (SCD) requiring cardiopulmonary bypass and open-heart surgery represent the proverbial "needle in the haystack". As such, there is some trepidation on the part of clinicians when these patients present for complex cardiac surgery. SCD is an autosomal, recessive condition that results from a single nucleotide polymorphism in the β-globin gene. Hemoglobin SS molecules (HgbSS) with this point mutation can polymerize under the right conditions, stiffening the erythrocyte membrane and distorting the cellular structure to the characteristic sickle shape. This shape change alters cellular transit through the microvasculature. As a result, circumstances such as hypoxia, hypothermia, acidosis or diminished blood flow can lead to aggregation, vascular occlusion and thrombosis. Chronically, SCD can give rise to multiorgan damage secondary to hemolysis and vascular obstruction. This review and case study details an 11-year-old African-American male with known SCD who presented to the cardiothoracic surgical service with congenital heart disease consisting of an anomalous, intramural right coronary artery arising from the left coronary sinus for surgical consultation and subsequent surgical correction. This case report will include a review of the pathophysiology and current literature regarding preoperative, intraoperative and postoperative management of SCD patients.

    Charcot spine, or neuropathic spinal arthropathy, involves the progressive destruction of the spinal joint due to the lack of normal protective sensations and proprioception. A rare cause of Charcot spine is congenital insensitivity to pain, which is an absent or abnormal response to painful stimuli. There are few case reports describing this condition, and long-term follow-up data are limited. The presentation and treatment of two patients with Charcot spine secondary to congenital insensitivity to pain are described. Both cases were characterized by lumbar involvement and were treated with circumferential decompression and an extended lumbo-pelvic fusion construct. The cases described here demonstrate stable neurological status at 1.5 and 5 years follow-up. Patient characteristics, pre- and post-operative imaging, operative approach, and outcomes are described. The literature regarding this rare condition is also reviewed, with an emphasis on operative management and outcomes. Surgical management is traditionally complicated by a high rate of hardware failure and adjacent segment degeneration. The current review highlights the importance of prompt and aggressive management following diagnosis of Charcot spine, as well as extended follow-up.

  5. Critical review of the epidemiologic literature regarding the association between congenital heart defects and exposure to trichloroethylene.

    The most recent Integrated Risk Information System review of trichloroethylene (TCE; CAS# 79-01-6) has suggested that congenital heart defects (CHD) are a critical endpoint associated with exposure to this solvent. This conclusion was drawn, at least partly, from epidemiologic data, including several relatively recent studies. The current article critically reviews this epidemiologic literature, focusing on study quality and consistency. Literature searches uncovered approximately a dozen studies that specifically addressed associations between TCE and congenital malformations in eight populations. Four of these reported positive associations between TCE and heart defects, with significant relative risks as high as 5-6 in some subgroups. However, each of the positive studies had substantial design or analytical flaws that could easily explain the results, thereby limiting the conclusions that can be drawn. Five studies found no positive association with TCE, and several of these reported substantially fewer cases than expected despite similar/higher exposures compared to positive studies, further detracting from causal conclusions. Overall, this epidemiologic literature provides no substantive or consistent evidence linking TCE to CHD.

    Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem.

    A de novo deletion of the long arm of chromosome 2 at 2q31-33 was observed in the fetal amniocyte G-banded karyotype performed because of possible multiple malformations identified by ultrasound at 23 weeks gestation. Two days after the uneventful term delivery of a 2.45 kg male, the neonate experienced cardiopulmonary decompensation and biochemical changes compatible with carbamoyl phosphate synthetase I (CPS I) deficiency (elevated ammonia with a peak of 948 micromol/L, deficiency of citrulline, and no increase in orotic acid). The child died on day 3 of life. Physical anomalies confirmed at autopsy included double superior vena cava, ectopic adrenal tissue, and metatarsus adductus. The autopsy also revealed histologic evidence consistent with CPS deficiency, most notably microvesicular steatosis of the liver and Alzheimer's Type II changes with hypertrophic astrocytes in the basal ganglia. A postnatal lymphocyte karyotype confirmed the chromosome 2q31-33 deletion. Enzyme analysis on postmortem liver tissue confirmed the diagnosis of CPS deficiency. CPS I is reported to be mapped to 2q35 by NCBI (http://www.ncbi.nlm.nih.gov/mapview/) and 2q34 by ENSEMBL (http://www.ensembl.org/). The UCSC Human Genome Browser July 2003 assembly also places the gene at 2q34 (http://genome.UCSC.edu/). Fluorescence in situ hybridization (FISH) analysis with a BAC clone (RP11-349G4) of CPS I demonstrated that one copy of the gene was deleted in this infant. Using additional probes corresponding to the bands in the region of deletion, we identified the deleted region as 2q32-2q34. Our observations support the CPS I map position (ENSEMBL, UCSC) at 2q34. Additionally, potential conditions associated with deletions narrowly defined by standard cytogenetic techniques merit consideration in prenatal counseling. As demonstrated here, deletions may not only result in malformations and mental retardation but also increase the likelihood of revealing mutated genes located in the undeleted

    1991-01-01

    Leber's congenital amaurosis is an autosomal recessive disorder, characterized by the onset of blindness before the age of 6 months, a variable fundus aspect and an absent or extremely pathological ERG. The disorder may be isolated or associated with systemic involvement, such as nephronophtisis (Senior-Loken syndrome), nephronophtisis, cone-shaped epiphyses of the hand and cerebellar ataxia (Saldino-Mainzer syndrome), vermis hypoplasia, oculomotor anomalies and respiratory problems in the neonatal period (Joubert syndrome) or cardiomyopathy. It should be differentiated from other forms or chorioretinal dystrophies (juvenile retinitis pigmentosa or congenital stationary night blindness), cortical blindness or maturation delay and metabolic disorders. Children with possible congenital Leber amaurosis should not only have a thorough ophthalmological examination, but should also be seen by a paediatrician experienced in metabolic disorders.

    Background: Several studies using animal models have shown that oxidative stress during pregnancy may play an important role in causing birth defects. Congenital anomalies affect an estimated 270,000 newborns who die during the first 28 days of life every year from different birth defects. Hence, at present many research works are going on to reduce the infant mortality from congenital anomaly.[1] Objective: The objective was to measure the oxidant and antioxidant level in the serum of newborn babies with the congenital anomaly and compare these levels with age and sex matched normal neonates. This is to identify any role of oxidative stress in the causation of congenital anomaly. Materials and Methods: This case-control study included 159 participants: 106 newborns with the congenital anomaly and 53 healthy newborns. The markers of oxidative stress like serum malondialdehyde (MDA) level, protein carbonyl (PC) level, and the activity of antioxidants such as Vitamin C, glutathione were measured in both cases (neonates with congenital anomaly) and controls (normal healthy neonates). These parameters were statistically compared. Results: MDA levels and PC levels were significantly higher (P < 0.0001), and Vitamin C and reduced glutathione levels were significantly lower (P < 0.0001), in newborns with congenital malformation than in healthy newborns. Conclusions: Increased lipid peroxidation and protein carbonylation might play an important role in the pathogenesis of congenital anomaly. Impairment of the free radical/antioxidant balance is leading to increased free radical damage in neonates with congenital malformation. PMID:26628809

    Inherited desmosomal diseases are characterised by skin and/or cardiac features. Dermatological features might be a clue in the determination of the underlying life-threatening cardiac disease. This article aims to propose a dermatological algorithm for the diagnosis of desmosomal diseases after a systematic review of published articles. Palmoplantar keratoderma (PPK), hair shaft anomalies and skin fragility are the major features in the 458 patients analysed. Isolated PPK or isolated hair shaft anomalies are associated with a desmosomal disease limited to skin. The combination of PPK and hair shaft anomalies was recorded in 161 patients, and this association is at high risk of cardiac disease (129/161, 80.1%). Skin features had led to cardiac monitoring in only 2.3% of those patients. We delineated three major phenotypes: the PPK-hair shaft anomalies-non-fragile skin subtype (77%), always associated with cardiac involvement; the PPK-hair shaft anomalies-skin fragility-normal cardiac function subtype (19.9%), frequently associated with PKP1 mutations; the PPK-hair shaft anomalies-skin fragility-cardiac involvement subtype (3.1%), always due to DSP mutations. Three mutation hotspots in DSP and JUP account for 90.8% of the patients with cardiac involvement. The combination of PPK and hair shaft anomalies justifies long-term cardiac monitoring.

  14. Localisation of male determining factors in man: a thorough review of structural anomalies of the Y chromosome.

    PubMed Central

    Davis, R M

    1981-01-01

    It is widely accepted that male determination in man depends on the presence of a factor or factors on the Y chromosome. These factors may be localised within the Y chromosome through the study of structural anomalies of the Y. A thorough review of seven different structural anomalies of the Y is presented: dicentric Y chromosomes, Y isochromosomes, ring Y chromosomes, Y; autosome, Y;X, and Y;Y translocations, and Y deletions. The evidence from these studies indicates that a gene or genes on the short arm or the Y near the centromere play a crucial role in the development of the testes. A few studies indicate that one or more factors on the long arm of the Y may also influence testicular development. If such a factor is present on the long arm, then it too must be very near the centromere. The theory that separate genes independently control the initial development and maturation of the tests (on the long and short arms of the Y, respectively) may be premature. Recently proposed arguments in its favour are examined. Some evidence also indicates the presence of a fertility factor on the non-fluorescent segment of the long arm. Relevant information on the H-Y antigen is discussed. PMID:7017147

    The aim of this review is to give a comprehensive and concise overview of coronary embryology and normal coronary anatomy, describe common variants of normal and summarize typical patterns of anomalous coronary artery anatomy. Extensive iconography supports the text, with particular attention to images obtained in vivo using non-invasive imaging. We have divided this article into three groups, according to their frequency in the general population: Normal, normal variant and anomaly. Although congenital coronary artery anomalies are relatively uncommon, they are the second most common cause of sudden cardiac death among young athletes and therefore warrant detailed review. Based on the functional relevance of each abnormality, coronary artery anomalies can be classified as anomalies with obligatory ischemia, without ischemia or with exceptional ischemia. The clinical symptoms may include chest pain, dyspnea, palpitations, syncope, cardiomyopathy, arrhythmia, myocardial infarction and sudden cardiac death. Moreover, it is important to also identify variants and anomalies without clinical relevance in their own right as complications during surgery or angioplasty can occur. PMID:27358682

    Fewer than 100 patients with partial chromosome 2p trisomy have been reported. Clinical features are variable and depend on the size of the duplicated segment, but generally include psychomotor delay, facial anomalies, congenital heart defect, and other abnormalities. We report a 560.49 kb duplication of chromosome 2p in a 13 month-old male with hydrocephaly, ventricular septal defect, partial agenesis of the corpus callosum, and bilateral Wilms tumor. After discovery of bilateral renal masses at four months of age, the child underwent neoadjuvant chemotherapy followed by right radical nephrectomy that revealed triphasic Wilms' tumor. A needle core biopsy on one of two lesions on the left kidney also revealed Wilms tumor. A partial left nephrectomy revealed focally positive margins that necessitated left flank radiotherapy. The tumor karyotype was 46,XY,t(7;8)(q36;p11)[8]/46,XY [12] while his constitutional karyotype was 46,XY, suggesting that the t(7;8)(q36;p11) was associated with the malignancy. Single nucleotide polymorphism (SNP) chromosome microarray analysis of peripheral blood identified a maternally-inherited 560.49 kb chromosome 2p24.3 duplication that involved four OMIM genes: NBAS, DDX1, MYCNOS, and MYCN. SNP array analysis of the tumor revealed the same 2p24.3 duplication. At present, the now 5-year-old boy continues to do well without clinical or radiographic evidence of recurrent disease. This case is instructive because the child's health insurer initially denied authorization for chromosome microarray analysis (CMA), and it took more than one year before such authorization was finally granted. That initial decision to deny coverage could have had untoward health implications for this child, as the identification of constitutional MYCN duplication necessitated surveillance imaging for a number of pediatric malignancies associated with MYCN overexpression/dysregulation.

    2007-06-01

    Congenital pseudarthrosis of the tibia continues to pose one of the most difficult problems in paediatric orthopaedic surgery. The surgical procedures most used for treating congenital pseudarthrosis of the tibia are intramedullary nailing associated with bone grafting, vascularized fibular graft and the Ilizarov external circular fixator. Even when union is achieved, the residual deformities in the affected limb often result in significant disability. These deformities include leg-length discrepancy, angular tibial deformities, ankle mortise valgus and fibular non-union. The Ilizarov method allows simultaneous excision of the pseudarthrosis site, correction of the deformity and lengthening. However, refractures, ankle joint stiffness, fibular non-union with progressive ankle valgus are frequent sequelae with the Ilizarov technique. The surgeon should know when to abandon reconstructive procedures and create a more functional patient with an amputation. The authors discuss the indications and results of the Ilizarov external fixator in two patients with this complex problem. In addition, a critical review of the current literature is undertaken.

    Congenital leukemias are a rare group of hematologic neoplasms with a wide range of clinical signs and symptoms. Here we reported a neonate presenting with jaundice, pleural effusion and ascites. The total protein and serum albumin were markedly low at 48 and 12 g/L. Computerized tomography showed the density of liver was asymmetry with several hypoechoic regions. Initial blood routine examination revealed only thrombocytopenia while blood white cells increased to 30.0×10(9)/L with 17% blast cells several days later. Bone marrow biopsy showed the proportion of blasts and promonocytes increased and she was diagnosed as acute monoblastic leukemia.

    A 1-year-old boy presented to us with congenital inability to flex his elbow. He had bilaterally absent biceps brachii and brachialis muscles, a rare condition. We performed pedicle latissimus dorsi musculocutaneous flaps to the left and right volar upper arm at 21 and 24 months of age, respectively, to create elbow flexors. By 4 years of age, he had excellent elbow flexion bilaterally with strength grade in excess of 4.5. In addition to discussing our patient’s treatment options, we discuss other potential causes of weak elbow flexion when faced with this clinical dilemma. PMID:18780113

    Congenital insensitivity to pain (CIP) is a rare autosomal recessive genetic disease caused by mutations in the SCN9A gene. We report a patient with the clinical features consistent with CIP in whom we detected a novel homozygous G2755T mutation in exon 15 of this gene. Routine electrophysiological studies are typically normal in patients with CIP. In our patient, these studies were abnormal and could represent the consequences of secondary complications of cervical and lumbosacral spine disease and associated severe Charcot's joints.

    Arteriovenous fistulas between the aorta and the azygous vein usually manifest as a continuous audible murmur mimicking a patent ductus arteriosus when observed at birth. Symptoms when present during childhood are related to dyspnea or cardiac insufficiency. Embolotherapy of congenital vascular malformations is possible. However when this less invasive treatment fails, surgical treatment is sometimes necessary. We describe the case of a 12-year-old child with a large thoracic arteriovenous fistula between the descending thoracic aorta and the azygous vein, which was closed successfully by coil embolization. Available data in the literature suggest that coil embolization of aorto-azygous fistulas is usually successful.

    The objective of this review is to analyze aspects of congenital malformation of the ear in relation to cochlear implantation in children. Having briefly described the in utero development of the ear and the classification of types of external, middle and inner ear malformation, five practical aspects of these malformations are discussed. It seems likely that the combination of bilateral profound sensorineural deafness with bilateral microtia severe enough to make a surgical approach to the cochlea difficult will be extremely uncommon. No such cases have been reported, although Klippel-Feil deformity seems the syndrome most likely to produce this set of circumstances. Abnormalities in the intratympanic course of the facial nerve have been associated with cochlear malformation, emphasizing the benefit of intra-operative facial nerve monitoring, and a technique suggested for safely avoiding an abnormally placed nerve. Fistulae of cerebrospinal fluid (CSF) and perilymph can complicate surgery and are relatively common in common cavity and Mondini malformations. Strategies for facilitating surgery in the presence of 'gushers', for measuring the pressure of a gusher and for placement of the cochlear implant electrode array are reviewed, with reports of fluctuating levels of electric current when implants lie in dysplastic cochleas. The relationship of implant performance to VIIIth nerve tissue in malformed cochleas is discussed, with a description of the histological findings in a common cavity cochlea. Techniques for identifying the absence of the cochlear nerve are reviewed. Stimulation of the facial nerve by cochlear implants has been described in cases of congenital malformation of the labyrinth but is relatively uncommon. Case reports of the benefit received by implanted children with congenital cochlear malformation have appeared since 1988. Most cases reported have not yet been followed for long enough to establish a clear picture of the outcome following

    Congenital pericardial defects are a rare anomaly, found during autopsy and cardiothoracic surgery. We describe a case of a 69-year-old female, with a right-sided congenital pericardial defect associated with a giant bronchogenic cyst (BC) found during surgery. The cyst was resected and the patient developed arrhythmia following surgery. A review of the literature in Japan was performed, focusing on congenital anomalies associated with pericardial defects and its pathogenesis. We paid particular attention to complications following thoracic surgery in patients with pericardial defects and indications of pericardial reconstruction in such patients. PMID:27621900

    A double-chambered right ventricle (DCRV) is a rare congenital heart disease and an uncommon cause of congestive cardiac failure. An anomalous muscle band divides the right ventricle into two cavities, causing variable degrees of obstruction. Echocardiography is considered a useful method for the diagnosis of this pathology, especially in children. An eight-year-old patient with a small ventricular septal defect (VSD) and double-chambered right ventricle presented with a history of palpitations, easy fatigability and recurrent fever. On presentation, she had features of congestive cardiac failure. A complete diagnosis was initially missed with transthoracic two-dimensional (2-D) echocardiography but later obtained based on transthoracic 2-D echocardiography with Doppler facility. This was confirmed with cardiac catheterisation. The patient was referred for surgical correction, which was successful. Due to the rarity of this condition and the consequences of missing the diagnosis, we present this case in order to highlight the rarity of this congenital heart disease in childhood.

    Neurotrophic keratitis (NK) is a rare degenerative disease of the cornea caused by an impairment of corneal sensory innervation, characterized by decreased or absent corneal sensitivity resulting in epithelial keratopathy, ulceration, and perforation. The aetiopathogenesis of corneal sensory innervation impairment in children recognizes the same range of causes as adults, although they are much less frequent in the pediatric population. Some extremely rare congenital diseases could be considered in the aetiopathogenesis of NK in children. Congenital corneal anesthesia is an extremely rare condition that carries considerable diagnostic and therapeutic problems. Typically the onset is up to 3 years of age and the cornea may be affected in isolation or the sensory deficit may exist as a component of a congenital syndrome, or it may be associated with systemic somatic anomalies. Accurate diagnosis and recognition of risk factors is important for lessening long-term sequelae of this condition. Treatment should include frequent topical lubrication and bandage corneal or scleral contact lenses. Surgery may be needed in refractory cases. The purpose of this review is to summarize and update data available on congenital causes and treatment of corneal hypo/anesthesia and, in turn, on congenital NK. PMID:26451380

    VACTERL association is a condition comprising multisystem congenital malformations, causing severe physical disability in affected individuals. It is typically defined by the concurrence of at least three of the following component features: vertebral anomalies (V), anal atresia (A), cardiac malformations (C), tracheo-oesophageal fistula (TE), renal dysplasia (R) and limb abnormalities (L). Vertebral anomaly is one of the most important and common defects that has been reported in approximately 60–95% of all VACTERL patients. Recent breakthroughs have suggested that genetic factors play an important role in VACTERL association, especially in those with vertebral phenotypes. In this review, we summarised the genetic studies of the VACTERL association, especially focusing on the genetic aetiology of patients with vertebral anomalies. Furthermore, genetic reports of other syndromes with vertebral phenotypes overlapping with VACTERL association are also included. We aim to provide a further understanding of the genetic aetiology and a better evidence for genetic diagnosis of the association and vertebral anomalies. PMID:27084730

    The authors describe a case of a megadolichobasilar anomaly associated with basilar impression, bilateral megadolichocarotid arteries and an occipito-vertebral anastomosis. The concurrence of these anomalies lends support to the hypothesis that congenital factors play a part in the origin of the megadolichobasilar anomaly.

    The current study presents the case of a female infant with pancreatic hemangioendothelioma (HE) and discusses this rare disease in terms of the clinical features, treatment principle and prognosis. An 8-month-old female with pancreatic HE was admitted to the Department of General Surgery in The Children's Hospital (Zhejiang University School of Medicine, Hangzhou, Zhejiang, China) on January 3, 2011, due to yellow skin and sclera that had been apparent for 1 week. Magnetic resonance imaging (MRI) showed dilatation in the left and right hepatic, common hepatic and common bile ducts, a pancreatic head mass of ~4.7×5.2 cm with a strong signal, and close linkage of the portal vein and mesenteric vessels to the mass. Laparotomy was performed on January 11, 2011. An intraoperative frozen specimen showed a benign tumor. Finally, Whipple surgery retaining the tumor was chosen. The patient was treated by fasting, gastrointestinal decompression, antibiotics and supportive treatment post-surgery. Jaundice disappeared rapidly following the surgery. The patient started eating at 1 week post-surgery and was discharged 1 week later. From the pathological results, a diagnosis of pancreatic HE was made, with no tumor invasion of the hepatic lymph nodes. During the follow-up visit at 28 months post-surgery, the child showed good growth and development. MRI showed that the mass size was ~2.4×2.0×1.5 cm, which was a significantly decrease from previously. Additionally, a literature search showed that from 1973 to the present date, only 9 studies on children with HE of the pancreas have been reported. Childhood pancreatic HE is a rare form of pancreatic vascular anomaly, mainly occurring in infants. If the tumor oppresses the duodenum and invades the mesenteric vessels, Whipple surgery retaining the tumor could be performed. PMID:26622572

    In this investigation of congenital muscular torticollis, 311 infants treated consecutively for congenital torticollis over an 8-year period (1995-2003) at the Pediatric Neurology Clinic of Istanbul Medical Faculty, Istanbul University, Turkey were reviewed retrospectively. The clinical presentation, associated abnormalities, treatment, and outcomes of the overall group and of subgroups divided according to an ultrasonography-based classification were evaluated. All patients were evaluated using a standard approach: cervical ultrasonography was performed, and the patients were divided into two subgroups. Each group was scanned for other anomalies, and outcomes were compared. The mean age at diagnosis was 2.3 months; patients included in this study were 138 males and 173 females. Two clinical subgroups, comprised of sternomastoid tumors 85% and postural torticollis 15%, were identified. Passive range of motion was the initial treatment recommended for all of the patients. Follow-up data were available for all 311 patients; 95% experienced total resolution and 5% experienced subtotal resolution. We conclude that the majority of children with congenital muscular torticollis experience total resolution of symptoms. The success rate of conservative treatment is primarily dependent on the patients' age at the initiation of exercises and ultrasonographic findings.

    Congenital ptosis is a rare condition characterized by lower positioning of the upper eyelid that is present at birth and is a clinical condition that is persistent if not treated. It may be unilateral or bilateral and may be associated with other ocular disorders or systemic conditions, including Marcus Gunn, Horner, and Duane syndromes. It is a benign condition but causes functional, cosmetic, and psychological problems in children. However, not all patients need to undergo surgery, and usually only patients at risk of amblyopia need a prompt surgical correction, while in other cases, surgery can be postponed. The grade of ptosis, the eyelid function, and the amblyopic risk are the parameters that affect the ophthalmologist’s decision on timing of surgery and the surgical technique to be used. In fact, there are several types of surgical techniques to correct a congenital ptosis, although very often more than one is needed to obtain an acceptable result. This paper reviews the causes of congenital ptosis and associated diseases. Particular emphasis is given to surgical management and different procedures available to correct the upper eyelid anomaly and avoid permanent damage to visual function. PMID:28280295

    The Sahel experienced a severe drought during the 1970s and 1980s after wet periods in the 1950s and 1960s. Although rainfall partially recovered since the 1990s, the drought had devastating impacts on society. Most studies agree that this dry period resulted primarily from remote effects of sea surface temperature (SST) anomalies amplified by local land surface-atmosphere interactions. This paper reviews advances made during the last decade to better understand the impact of global SST variability on West African rainfall at interannual to decadal time scales. At interannual time scales, a warming of the equatorial Atlantic and Pacific/Indian Oceans results in rainfall reduction over the Sahel, and positive SST anomalies over the Mediterranean Sea tend to be associated with increased rainfall. At decadal time scales, warming over the tropics leads to drought over the Sahel, whereas warming over the North Atlantic promotes increased rainfall. Prediction systems have evolved from seasonal to decadal forecasting. The agreement among future projections has improved from CMIP3 to CMIP5, with a general tendency for slightly wetter conditions over the central part of the Sahel, drier conditions over the western part, and a delay in the monsoon onset. The role of the Indian Ocean, the stationarity of teleconnections, the determination of the leader ocean basin in driving decadal variability, the anthropogenic role, the reduction of the model rainfall spread, and the improvement of some model components are among the most important remaining questions that continue to be the focus of current international projects.

    A new type of anomaly is discussed that afflicts certain non-linear sigma models with fermions. This anomaly is similar to the ordinary gauge and gravitational anomalies since it reflects a topological obstruction to the reparametrization invariance of the quantum effective action. Nonlinear sigma models are constructed based on homogeneous spaces G/H. Anomalies arising when the fermions are chiral are shown to be cancelled sometimes by Chern-Simons terms. Nonlinear sigma models are considered based on general Riemannian manifolds. 9 refs. (LEW)

  17. Genetics of congenital hypothyroidism

    PubMed Central

    Park, S; Chatterjee, V

    2005-01-01

    Congenital hypothyroidism is the most common neonatal metabolic disorder and results in severe neurodevelopmental impairment and infertility if untreated. Congenital hypothyroidism is usually sporadic but up to 2% of thyroid dysgenesis is familial, and congenital hypothyroidism caused by organification defects is often recessively inherited. The candidate genes associated with this genetically heterogeneous disorder form two main groups: those causing thyroid gland dysgenesis and those causing dyshormonogenesis. Genes associated with thyroid gland dysgenesis include the TSH receptor in non-syndromic congenital hypothyroidism, and Gsα and the thyroid transcription factors (TTF-1, TTF-2, and Pax-8), associated with different complex syndromes that include congenital hypothyroidism. Among those causing dyshormonogenesis, the thyroid peroxidase and thyroglobulin genes were initially described, and more recently PDS (Pendred syndrome), NIS (sodium iodide symporter), and THOX2 (thyroid oxidase 2) gene defects. There is also early evidence for a third group of congenital hypothyroid conditions associated with iodothyronine transporter defects associated with severe neurological sequelae. This review focuses on the genetic aspects of primary congenital hypothyroidism. PMID:15863666

    Introduction Congenital heart diseases (CHD) are common causes of cardiovascular morbidity and mortality among young children and adolescents living in Africa. Accurate epidemiological data are needed in order to evaluate and improve preventive strategies. This review aims to determine the prevalence of CHD and their main patterns in Africa. Methods and analysis This systematic review and meta-analysis will include cross-sectional, case–control and cohort studies of populations residing inside African countries, which have reported the prevalence of CHD, confirmed by an echocardiographic examination and/or describing different patterns of these abnormalities in Africa. Relevant abstracts published without language restriction from 1 January 1986 to 31 December 2016 will be searched in PubMed, Exerpta Medica Database and online African journals as well as references of included articles and relevant reviews. Two review authors will independently screen, select studies, extract data and assess the risk of bias in each study. The study-specific estimates will be pooled through a random-effects meta-analysis model to obtain an overall summary estimate of the prevalence of CHD across studies. Clinical and statistical heterogeneity will be assessed, and we will pool studies judged to be clinically homogeneous. On the other hand, statistical heterogeneity will be evaluated by the χ2 test on Cochrane's Q statistic. Funnel-plots analysis and Egger's test will be used to detect publication bias. Results will be presented by geographic region (central, eastern, northern, southern and western Africa). Ethics and dissemination The current study will be based on published data, and thus ethical approval is not required. This systematic review and meta-analysis is expected to serve as a base which could help in estimating and evaluating the burden of these abnormalities on the African continent. The final report of this study will be published in a peer-reviewed journal. Trial

    2004-01-01

    Bangui anomaly is the name given to one of the Earth s largest crustal magnetic anomalies and the largest over the African continent. It covers two-thirds of the Central African Republic and therefore the name derives from the capitol city-Bangui that is also near the center of this feature. From surface magnetic survey data Godivier and Le Donche (1962) were the first to describe this anomaly. Subsequently high-altitude world magnetic surveying by the U.S. Naval Oceanographic Office (Project Magnet) recorded a greater than 1000 nT dipolar, peak-to-trough anomaly with the major portion being negative (figure 1). Satellite observations (Cosmos 49) were first reported in 1964, these revealed a 40nT anomaly at 350 km altitude. Subsequently the higher altitude (417-499km) POGO (Polar Orbiting Geomagnetic Observatory) satellite data recorded peak-to-trough anomalies of 20 nT these data were added to Cosmos 49 measurements by Regan et al. (1975) for a regional satellite altitude map. In October 1979, with the launch of Magsat, a satellite designed to measure crustal magnetic anomalies, a more uniform satellite altitude magnetic map was obtained. These data, computed at 375 km altitude recorded a -22 nT anomaly (figure 2). This elliptically shaped anomaly is approximately 760 by 1000 km and is centered at 6%, 18%. The Bangui anomaly is composed of three segments; there are two positive anomalies lobes north and south of a large central negative field. This displays the classic pattern of a magnetic anomalous body being magnetized by induction in a zero inclination field. This is not surprising since the magnetic equator passes near the center of this body.

    In this chapter we briefly address the most common congenital brain and spinal anomalies as well as their most salient imaging, especially magnetic resonance, findings. Some of them, such as Chiari II, and open spinal defects, have become relatively rare due to their detection in utero and repair of the spinal malformation. Regardless of the type of brain anomaly, the most common clinical symptoms are mental retardation, hydrocephalus, and seizure; the latter two may need to be surgically and medically addressed. The most commonly found spinal congenital anomalies include the filum terminale lipoma which is generally asymptomatic and incidental and the caudal regression syndrome for which no primary treatment exists. Any spinal congenital anomaly may present in adulthood as a consequence of spinal cord tethering and/or development of syringomyelia.

    Ebstein anomaly is a rare congenital heart defect. Many nurses have probably never encountered this anomaly, with very few able to accurately depict the pathological anatomy of the condition. As technology further develops, providers are better equipped to recognize and manage Ebstein anomaly. There are important considerations for nurses when caring for an individual with Ebstein anomaly. The aim of this article is to give an overview of the condition exploring the pathophysiology, how patients typically present, and how to effectively care for a patient with Ebstein anomaly regarding medical and surgical courses of treatment. It is important for nurses to have a resource to reference on Ebstein anomaly, and the majority of current literature is solely based for medical providers. Furthermore, Ebstein patients may be seen on a variety of units in the hospital beyond cardiology (i.e., pregnant patient with a diagnosis of Ebstein anomaly).

    A 28-year-old presented with complaints of severe pain and redness in the left eye since 2 weeks. He had similar complaints in the right eye 2 years back for which he had undergone a scleral patch graft. Best corrected visual acuity was 20/20 in both eyes. The right had a well vascularized scleral graft and rest of the anterior segment was normal. The left eye had inferior conjunctival congestion with an area of the scleral melt with uveal show just temporal to the limbus in the interpalbebral area. The cornea was clear and anterior chamber was quiet in the left eye. Applanation tonometry and fundus evaluation were normal in both eyes. Physical examination revealed hyperpigmented skin lesion, hypertrichosis and absorption of distal phalanges. Laboratory, ocular and physical findings confirmed the diagnosis of congenital erythropoietic porphyria. He was on oral steroids 40 mg/day since 2 weeks and topical antibiotics and lubricants. He was advised to continue the same and was taken up for scleral patch graft with fibrin glue in the left eye. Postoperatively he was continued on topical and oral steroids and lubricants.3 weeks later the left eye had stabilized however patient came with a melt in the right eye. Since it was an early melt, we went ahead with cyanoacrylate glue and bandage contact lens in the right eye and started him on topical steroids for the right eye also. Three months later both the eyes were stable, and the patient was gradually tapered off the steroids.

    To characterise congenital mesoblastic nephroma (CMN), with special emphasis on polyhydramnios and the neonatal prognosis, we summarise 31 CMN patients (30 reported patients and the present patient). CMN was detected at a median of 30 weeks' gestation, and infants were delivered at a median of 34 weeks' gestation. Of 27 patients with available data, 19 (70%) had polyhydramnios, of which 8 required amnio- drainage. Women with amnio-drainage gave birth significantly earlier (30.4 weeks' gestation) than those without polyhydramnios (36.7 weeks' gestation). Thus, CMN was frequently associated with polyhydramnios and this polyhydramnios was associated with a significant increase in the risk of preterm birth. Of 20 patients with available data, the affected-side kidney was 'compressed' in 16 and 'replaced' in 4: polyhydramnios was present in a half vs 100%, respectively, suggesting that a 'replaced' kidney may suggest a more aggressive tumour and may be associated with a poorer prognosis. Univariate analysis showed that early gestational week at diagnosis was the only feature significantly associated with poor prognosis. Thus, polyhydramnios, 'replaced' kidney and early gestational week at diagnosis, may indicate poor prognosis, to which obstetricians should pay attention.

    2012-01-01

    Background Congenital nasal pyriform aperture stenosis is a rare and potentially lethal form of airway obstruction in newborns. Immediate recognition and appropriate therapy are mandatory for this potentially life-threating condition. This anomaly may present as an isolated malformation or may be associated with other cranial-facial anomalies. Clinically, CNPS shows unspecific symptoms of nasal airway obstruction such as apnoic crisis, episodic cyanosis and inability to nurse. The purpose of this report is to present author's experience in the surgical management of this rare pathology in 3 patients. Patients and Methods Three cases of congenital nasal pyriform aperture stenosis were reviewed for presentation of the disorder, management and effectiveness of the surgical treatment. Results All the patients underwent a surgical correction of the pyriform aperture stenosis using a sublabial approach followed by nasal stenting. During the follow-up no cases of restenosis, respiratory failure or cyanosis were detected. Conclusions Congenital pyriform aperture stenosis should be suspected in newborns with clinical signs of severe nasal obstruction associated with a difficulty to pass a small catheter though the anterior nasal valve. Timely recognition is mandatory to prevent a potential deadly outcome. Surgical correction of the stenosis though a sublabial approach followed by a nasal stenting revealed to be most effective treatment for these patients. PMID:22731387

    This review synthesizes the empirical literature on outcomes and experiences of transfer and transition from pediatric to adult care for young people with congenital heart disease. A systematic review of papers published between January 2001 and May 2013 that examined outcomes or experiences of transfer and transition among young people with congenital heart disease was conducted. Data were extracted by two independent reviewers with the outcomes data combined using narrative synthesis and the experiences data integrated using thematic synthesis. Thirteen papers were included in the review: six reported outcomes following transfer, six reported experiences of transfer and transition, and one reported both outcomes and experiences. The review data indicate that high proportions of young people were lost to follow-up or experienced long gaps in care after leaving pediatric cardiology. Factors that protected against loss to follow-up or lapse in care included: beliefs that specialized adult care was necessary; poorer health status; attendance at pediatric appointments without parents; and pediatric referral to an adult congenital heart disease center. Data on experiences highlighted that many young people were unconcerned about transition, but lacked knowledge about their condition and were insufficiently prepared for transfer. In terms of adult services, many young people desired continuity in the quality of care, youth-oriented facilities, a personalized approach, and for their parents to remain involved in their care, but in a secondary, supportive capacity. In conclusion, the high proportions of young people lost to follow-up highlight the need for formal transition programs, which ensure a planned and coordinated transfer. Patients with congenital heart disease need education throughout adolescence about the implications of their condition, the differences between pediatric and adult services, and self-care management.

Soon after birth he started to show bradypnea, bradycardia and cyanosis, being submitted to tracheal intubation and started empiric antibiotic therapy for suspected early neonatal sepsis. During hospitalization in the NICU, he showed difficulty to undergo extubation due to episodes of desaturation during sleep and wakefulness. He had recurrent episodes of hypoglycemia, hyperglycemia, metabolic acidosis, abdominal distension, leukocytosis, increase in C-reactive protein levels, with negative blood cultures and suspected inborn error of metabolism. At 2 months of age he was diagnosed with long-segment Hirschsprung's disease and was submitted to segment resection and colostomy through Hartmann's procedure. A genetic research was performed by polymerase chain reaction for CCHS screening, which showed the mutated allele of PHOX2B gene, confirming the diagnosis. Comments: This is a rare genetic, autosomal dominant disease, caused by mutation in PHOX2B gene, located in chromosome band 4p12, which results in autonomic nervous system dysfunction. CCHS can also occur with Hirschsprung's disease and tumors derived from the neural crest. There is a correlation between phenotype and genotype, as well as high intrafamilial phenotypic variability. In the neonatal period it can simulate cases of sepsis and inborn errors of metabolism. PMID:26838603

    Lingual hamartoma is a rare finding of congenital midline posterior tongue mass. The lesion may be seen as a single anomaly or maybe associated with syndrome especially the Oral Facial Digital Syndrome (OFDS). Here, we report an otherwise normal and healthy two-month-old boy with a congenital midline base of tongue mass presented with snoring and episodic vomiting since the age of 1 month. Tumour excision from the area of foramen of caecum recovered a pinkish pedunculated tumour. Histopathology examination confirmed the diagnosis of leiomyomatous lingual hamartoma. Differential diagnosis, especially for midline tongue mass and other paediatric tongue lesions are discussed. We also discuss the epidemiology, histopathologic features, treatment and prognosis of lingual hamartoma based on the literature review. PMID:27790477

    With the success of modern surgical techniques for congenital heart disease, the population of women of childbearing age with congenital heart disease is growing. Because of the significant hemodynamic load of pregnancy, labor, and delivery, women with congenital heart disease require preconceptual risk assessment and expert multidisciplinary care throughout pregnancy. The aim of this review is to discuss the management of cardiovascular, obstetric, and fetal care issues that are commonly encountered during pregnancy in women with congenital heart disease.

    Left ventricular noncompaction (LVNC) is a relatively common genetic cardiomyopathy, characterized by prominent trabeculations with deep intertrabecular recesses in mainly the left ventricle. Although LVNC often occurs in an isolated entity, it may also be present in various types of congenital heart disease (CHD). The most prevalent CHD in LVNC is Ebstein anomaly, which is a rare form of CHD characterized by apical displacement and partial fusion of the septal and posterior leaflet of the tricuspid valve with the ventricular septum. Several reports of sporadic as well as familial cases of Ebstein anomaly associated with LVNC have been reported. Recent studies identified mutations in the MYH7 gene, encoding the sarcomeric β-myosin heavy chain protein, in patients harboring this specific phenotype. Here, we will review the association between Ebstein anomaly, LVNC and mutations in MYH7, which seems to represent a subtype of Ebstein anomaly with autosomal dominant inheritance and variable penetrance.

    Maternal hypertension is common during pregnancy, and multiple studies have reported on an association between maternal hypertension and congenital heart defects (CHDs) in offspring; however, there is variability in the quality of these studies. A systematic review and meta-analysis was conducted on the associations between untreated and treated maternal hypertension and the risk of CHDs, evaluating CHDs overall as well as specific CHD subtypes. A systematic search of peer-reviewed articles published before August 2013 identified 16 studies evaluating the associations between untreated and treated maternal hypertension and CHDs. Summary relative risk (RR) estimates were calculated using fixed-effects models and random-effects models. Significant associations were observed between maternal hypertension and overall CHDs, for both treated [RR 2.0; 95 % confidence interval (CI) 1.5, 2.7] and untreated (RR 1.4; 95 % CI 1.2, 1.7) hypertension, as well as for overall hypertension regardless of treatment status (RR 1.8; 95 % CI 1.5, 2.2). The magnitude of effect was similar for the majority of CHD subtypes evaluated. The effects were also similar among women with hypertension who used one of multiple specific hypertension medications. There was no evidence of publication bias, and our results were robust to several factors considered in sensitivity analyses (e.g., source of exposure data, adjustment for potential confounders, and study design). Maternal hypertension was associated with CHDs. By understanding the specific mechanisms involved, appropriate strategies may be developed to reduce this risk, in order to prevent CHDs.

    2011-01-01

    Congenital corneal opacification (CCO) encompasses a broad spectrum of disorders that have different etiologies, including genetic and environmental. Terminology used in clinical phenotyping is commonly not specific enough to describe separate entities, for example both the terms Peters anomaly and sclerocornea have been ascribed to a clinical picture of total CCO, without investigating the presence or absence of iridocorneal adhesions. This is not only confusing but also unhelpful in determining valid genotype-phenotype correlations, and thereby revealing clues for pathogenesis. We undertook a systematic review of the literature focusing on CCO as part of anterior segment developmental anomalies (ASDA), and analyzed its association specifically with chromosomal abnormalities. Genes previously identified as being associated with CCO are also summarized. All reports were critically appraised to classify phenotypes according to described features, rather than the given diagnosis. Some interesting associations were found, and are discussed.

    Pediatric congenital intracranial infections are a group of different and important entities that constitute a small percentage of all pediatric infections. The causal factors and clinical presentations are different in children compared with adults. They require early recognition because delay diagnosis and initiation of treatment may have catastrophic consequences. Despite improvements in prenatal screening, vaccine safety, and antibiotics, infections of the central nervous system remain an important cause of neurological disabilities worldwide. This article reviews the most common congenital infections and their imaging findings.

As patients now survive into adulthood, adult health-care providers must also be familiar with this condition. Over the past several years, F1000 has published numerous commentaries updating research and practical guidelines for this condition. The purposes of this review are to summarize basic information defining congenital adrenal hyperplasia and to highlight current knowledge and controversies in management. PMID:26339484

    Congenital thrombophilia is a thrombotic diathesis caused by a variety of genetic abnormalities in blood coagulation factors or their inhibitory factors associated with physiological thrombus formation. Patients with congenital thrombophilia often present with unusual clinical episodes of venous thrombosis (occasionally combined with pulmonary embolism, known as venous thromboembolism) at a young age and recurrence in atypical vessels, such as the mesenteric vein and superior sagittal sinus, often with a family history of this condition. Studies in Japan as well as in western countries have shown congenital thrombophilia to be caused by a wide variety of genetic abnormalities in natural anticoagulant proteins, such as antithrombin, protein C, and protein S. However, there may still be many unknown causes of hereditary thrombosis. We recently reported a case of hereditary thrombosis induced by a novel mechanism of antithrombin resistance, that is, congenital thrombophilia caused by a gain-of-function mutation in the gene encoding the coagulation factor prothrombin.

    Summary: Congenital symmastia is a medial confluence of the breasts. It is a rare anomaly with few reports in the literature and no standard treatment. In this article, we present a case of congenital symmastia treated by 3 steps: liposuction, fixation of the skin to the chest wall in the area of the intermammary sulcus, and postoperative intermammary compression. A successful result was achieved with normal cleavage between the breasts. So, this is considered the ideal treatment for this condition.

    Congenital diarrhoea of heterogenic etiology is a rare cause of chronic diarrhoea. Characteristic features are: onset in the first weeks of life, life-threatening severe dehydratation and electrolyte disorders leading to a necessity of long-term parenteral nutrition. The clinical onset may be delayed and the degree of diarrhoea may be modest, making the diagnosis difficult. The main causes of congenital diarrhoea such as intestine electrolytes, carbohydrates, lipid and protein transport disorders and congenital enzymatic deficiencies, enterocyte polarization disorders, hormonal, immunological, metabolic, genetic and congenital anatomic disorders are presented in the paper. Some of them, such as: microvillus inclusion disease, tufting enteropathy, intestinal anedocrynosis, IPEX syndrome (immunodysregulation polyendocrinopathy enteropathy X-linked syndrome) have been described recently. One of the basic investigations, when congenital diarrhea is suspected, is general examination of the stool, its electrolyte concentration and serum electrolytes and blood gas analysis. Often, small bowel biopsy with histological examination (with the use of electronic microscopy and PAS staining) is indicated. In some cases molecular examination is possible and indicated. In differential diagnosis other, more frequent causes of chronic diarrhea of infancy, have to be excluded. In most of the cases of congenital diarrhoea there is no casual treatment available - usually long-term parenteral nutrition is necessary.

    INTRODUCTION Congenital anomalies are a rare cause of pancreatitis in adults. Gastric duplications are the least common duplication of the gastrointestinal tract and are even more uncommon in the setting of a duplicate pancreas. PRESENTATION OF CASE This manuscript contains a case report and review of the literature of an adult who presented with recurrent pancreatitis and was found to have a gastric duplication cyst that communicated with a duplicate pancreas. The study aim is to alert practitioners to the duplicate anomaly and recommend appropriate therapy. DISCUSSION Combined gastric and pancreatic duplications usually occur in young females with nonspecific, recurrent abdominal pain. This combined duplication can result in pancreatitis when the gastric duplication is contiguous with the stomach. Heightened awareness of the condition, appropriate diagnostics with accurate interpretation and a minimalist approach to resection are warranted. CONCLUSION Recurrent abdominal pain and pancreatitis in young adults devoid of risk factors should lead to consideration of congenital anomalies. Not all cysts near the pancreas and stomach are pseudocysts. ECRP and abdominal CT/MRI provide critical diagnostic information. This dual anomaly is best treated by simple excision of the gastric duplication and heterotopic pancreas. PMID:23827696

    Congenital cataract is a type of cataract that presents at birth or during early childhood, and it is one of the most easily treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1-6 cases per 10,000 live births. Approximately 50% of all congenital cataract cases may have a genetic cause, and such cases are quite heterogeneous. Although congenital nuclear cataract can be caused by multiple factors, genetic mutation remains the most common cause. All three types of Mendelian inheritance have been reported for cataract; however, autosomal dominant transmission seems to be the most frequent. The transparency and high refractive index of the lens are achieved by the precise architecture of fiber cells and homeostasis of the lens proteins in terms of their concentrations, stabilities, and supramolecular organization. Research on hereditary congenital cataract has led to the identification of several classes of candidate genes that encode proteins such crystallins, lens-specific connexins, aquaporin, cytoskeletal structural proteins, and developmental regulators. In this review, we highlight the identified genetic mutations that account for congenital nuclear cataract.

    The Klippel-Feil syndrome (KFS) has been reported to be associated with intracranial neoplasms, most frequently epidermoid or dermoid cysts. To our knowledge, however, patients who present with a posterior fossa dermoid cyst (DC) and KFS are extremely rare with only 24 previously reported cases in the English literature worldwide. Therefore, we present the first report of a patient with a craniocervical ruptured DC accompanied by craniovertebral junction (CVJ) anomalies, KFS and mirror movement. Meanwhile, a literature review of KFS accompanying with posterior fossa DC discusses these conditions from the embryological, anatomical, clinical and therapeutic perspectives. Additionally, the combination of CVJ anomalies, KFS and DC may represent a new syndrome that has previously gone unnoticed.

    Noninvasive rehabilitation strategies for children with unilateral cerebral palsy are routinely used to improve hand motor function, activity, and participation. Nevertheless, the studies exploring their effects on brain structure and function are very scarce. Recently, structural neuroplasticity was demonstrated in adult poststroke patients, in response to neurorehabilitation. Our purpose is to review current evidence on the effects of noninvasive intervention strategies on brain structure or function, in children with unilateral cerebral palsy. The main literature databases were searched up to October 2013. We included studies where the effects of upper limb training were evaluated at neurofunctional and/or neurostructural levels. Only seven studies met our selection criteria; selected studies were case series, six using the intervention of the constraint-induced movement therapy (CIMT) and one used virtual reality therapy (VR). CIMT and VR seem to produce measurable neuroplastic changes in sensorimotor cortex associated with enhancement of motor skills in the affected limb. However, the level of evidence is limited, due to methodological weaknesses and small sample sizes of available studies. Well-designed and larger experimental studies, in particular RCTs, are needed to strengthen the generalizability of the findings and to better understand the mechanism of intervention-related brain plasticity in children with brain injury.

    Fibrodysplasia ossificans progressiva (FOP) is a rare but extremely disabling genetic disease of the skeletal system. This disease is characterized by progression of heterotopic ossification within skeletal muscles, ligaments and tendons. Most patients with FOP are misdiagnosed early in life before the appearance of heterotopic ossification and undergo diagnostic procedures such as biopsy that can cause lifelong disability. Almost all of the patients have some peculiar congenital anomalies, including short great toes, hallux valgus, short thumbs and hypoplasia of digital phalanges. These congenital defects support the diagnosis of FOP, but are not constantly observed in the totality of patients. If necessary, genetic studies can be performed to confirm the diagnosis. Once diagnosed, patients should be advised in order to avoid unnecessary traumas, surgical procedures, biopsies, intramuscular injections and vaccinations. Here, we describe a patient with FOP without characteristic congenital skeletal anomalies.

    This article contains a review of some of the most important publications on congenital heart disease and pediatric cardiology that appeared in 2010 and up until September 2011. Of particular interest were studies on demographic changes reported in this patient population and on the need to manage the patients' transition from the pediatric to the adult cardiology department. This transition has given rise to the appearance of new areas of interest: for example, pregnancy in women with congenital heart disease, and the effect of genetic factors on the etiology and transmission of particular anomalies. In addition, this review considers some publications on fetal cardiology from the perspective of early diagnosis and, if possible, treatment. There follows a discussion on new contributions to Eisenmenger's syndrome and arrhythmias, as well as on imaging techniques, interventional catheterization and heart transplantation. Finally, there is an overview of the new version of clinical practice guidelines on the management of adult patients with congenital heart disease and of recently published guidelines on pregnancy in women with heart disease, both produced by the European Society of Cardiology.

    Objective: To assess the natural history of congenital myopathies (CMs) due to different genotypes. Methods: Retrospective cross-sectional study based on case-note review of 125 patients affected by CM, followed at a single pediatric neuromuscular center, between 1984 and 2012. Results: Genetic characterization was achieved in 99 of 125 cases (79.2%), with RYR1 most frequently implicated (44/125). Neonatal/infantile onset was observed in 76%. At birth, 30.4% required respiratory support, and 25.2% nasogastric feeding. Twelve percent died, mainly within the first year, associated with mutations in ACTA1, MTM1, or KLHL40. All RYR1-mutated cases survived and did not require long-term ventilator support including those with severe neonatal onset; however, recessive cases were more likely to require gastrostomy insertion (p = 0.0028) compared with dominant cases. Independent ambulation was achieved in 74.1% of all patients; 62.9% were late walkers. Among ambulant patients, 9% eventually became wheelchair-dependent. Scoliosis of variable severity was reported in 40%, with 1/3 of (both ambulant and nonambulant) patients requiring surgery. Bulbar involvement was present in 46.4% and required gastrostomy placement in 28.8% (at a mean age of 2.7 years). Respiratory impairment of variable severity was a feature in 64.1%; approximately half of these patients required nocturnal noninvasive ventilation due to respiratory failure (at a mean age of 8.5 years). Conclusions: We describe the long-term outcome of a large cohort of patients with CMs. While overall course is stable, we demonstrate a wide clinical spectrum with motor deterioration in a subset of cases. Severity in the neonatal/infantile period is critical for survival, with clear genotype-phenotype correlations that may inform future counseling. PMID:25428687

    Summary The incidence of congenital artery anomalies is 0.2–1.4%, and most are benign. Single coronary artery (SCA) anomalies are very rare. The right coronary artery (RCA) originating from the left coronary system is one such SCA anomaly, and the risk of sudden cardiac death (SCD) increases if it courses between the pulmonary artery and aorta and coexists with other congenital heart diseases. Additionally, coursing of the RCA between the great vessels increases the risk of atherosclerosis. We herein present the case of a 57 year-old man who was admitted to our cardiology outpatient clinic and diagnosed with an SCA anomaly in which the RCA arose from the left main coronary artery (LMCA) and coursed between the pulmonary artery and aorta. However a critical stenosis was not detected in imaging techniques, and myocardial perfusion scintigraphic evidence of ischaemia was found in a small area. Therefore, he was managed with conservative medical therapy. PMID:26668781

  18. Developmental anomalies of the scapula-the "omo"st forgotten bone.

    PubMed

    Williams, Marc S

    2003-08-01

    Congenital malformations of the scapula, ranging from complete absence, to abnormal shape and position (Sprengel anomaly) are encountered, not infrequently, in genetic practice. Despite this, little is known of the embryologic origin of the scapula and the relationship of the embryology to the observed birth defects. Standard embryology texts, when discussing the subject at all, generally consider the scapula as part of the upper limb. The pattern of associated birth defects suggests that this is at least an oversimplification and may be inaccurate. Sprengel anomaly is the most frequently encountered malformation of the scapula. It can be seen in isolation, but is often seen in association with other defects that include; scoliosis, hemivertebrae, segmentation abnormalities of vertebrae and ribs (including Klippel-Feil sequence), spina bifida, clavicular abnormalities, renal abnormalities and hypoplasia of the muscles of the neck and shoulder. The ipsilateral limb is usually normal. An unappreciated association between Sprengel anomaly and diastematomyelia of the lumbar spine also raises questions about the embryologic origin of the scapula. 25-50% of Sprengel anomaly patients have an associated omovertebral band or bone that arises from the posterior process of a vertebral body and attaches to the superior angle/medial portion of the scapula. This is felt to be of scapular origin, but the report of at least one patient with an omovertebral bone, not associated with a Sprengel anomaly questions this assumption. Scapuloiliac dysostosis (Kosenow syndrome), a rare skeletal dysplasia, is associated with marked hypoplasia of the scapulae, clavicles and pelvis. Associated anomalies include eye anomalies, rib anomalies and spina bifida. The limbs are normal. Knockout of the Emx2 gene in mice yields a similar skeletal phenotype. Mutations in EMX2 in humans are associated with schizencephaly, not skeletal anomalies. Data on gene expression in the scapula will be reviewed

    Congenital dislocation of the knee is a rare disease. The diagnosis is made at birth by clinical findings, and confirmed radiologically. It has been associated with various etiologies from intrauterine fetal malpositions to genetic disorders. The prognosis depends on early treatment and whether there are other congenital anomalies. We report two new cases of congenital dislocation of the knee, observed in our hospital during the period of a month, diagnosed immediately after birth, and both with a good clinical outcome.

    We report a 6 years old male child, presented with difficulty in swallowing, crying and smiling from early infancy and recurrent episodes of cyanosis on exertion for about 2 years. He had facial dysmorphism, clubbing and polydactyly and right sided lower motor neuron type of facial nerve palsy. On examination and relevant investigations findings were consistent with Moebius syndrome and Taussig-Bing anomaly. Moebius syndrome comprises of congenital facial nerve palsy with or without palsy of the other cranial nerves and the associated organ system malformations. Taussig-Bing anomaly is a rare congenital heart malformation consisting of a transposed aorta, a large pulmonary artery which arises primarily from the right ventricle and ventricular septal defect. Simultaneous occurrence of Moebius syndrome and Taussig-Bing anomaly has not yet been reported in the past.

    Hepatic pulmonary fusion is a rare malformation associated with right congenital diaphragmatic hernia (CDH), often only discovered during surgical repair of the defect. Fourteen previous cases have been reported in the literature. We describe a case of a full term male newborn with prenatal ultrasound diagnosis of right CDH who underwent a thoracoscopy converted to a thoracotomy, due to this rare aforementioned intraoperative incidental finding. We reviewed the previous reported literature, especially focusing on the chosen surgical approach, concluding that an early and appropriate preoperative imaging investigation may be crucial for the best management of these kinds of patients.

    We describe a case of a female with simple virilizing congenital adrenal hyperplasia (CAH) reared as a male diagnosed at the late age of 64. Computed Tomography (CT) demonstrated a large adrenal mass, bilateral diffuse adrenal enlargement, female pelvic organs as well as a clearly visualized prostate gland. This is to the best of our knowledge the first case of such a sizable prostate gland in a female CAH patient documented on CT. We review the literature regarding aspects where radiologists may encounter CAH and the finding of presence of a prostate gland in female CAH patients. PMID:24421935

    Congenital torticollis is a very common postural deformity, characterized by a more or less severe retraction of sternocleidomastoid muscle. Any treatment, else that "good sense" counsels given to the parents, is indicated. The evolution is spontaneously favorable in the majority of cases before the age of one year old. The elimination of differential diagnosis (vertebral and/or neurological malformations, ocular, tumor) is the key-point. Screening of congenital hip dislocation is mandatory because the physiopathology is the same in both diseases. A remaining torticolis after 18 months of age may be an indication to sternocleidomastoid muscle lengthening.

    This paper reviews current concepts and results in the management of congenital tracheal stenosis (CTS). Diagnostic options are considered and the requirements for successful management defined. Chief amongst these is a multi-disciplinary approach with individualised patient management. Severe long-segment CTS represents the biggest challenge to clinicians and the worst problems for affected families. Near-death episodes are frequent in affected infants and some cannot be ventilated and require ECMO. Associated cardiovascular anomalies are frequent. Patients require immediate resuscitation and transfer to a specialist unit. After careful assessment, accurate diagnosis and discussion, primary resection and end-to-end repair with a slide technique should always be the first option, with concomitant repair of associated cardiac anomalies. If this is impossible because of the severity of the lesion, some form of patch tracheoplasty will be indicated. Cardiopulmonary bypass is often required. Patches include pericardium, autograft trachea, carotid artery, cartilage, and allograft trachea. Mortality ranges from 0 to 30% in the literature, which largely comprises single-centre long-term experience. Recurrence is common and can be managed by stenting and tracheal homograft implantation. Long-term quality of life of survivors is little reported but seems good. Physiological data are lacking. To improve results, we suggest a treatment algorithm to rationalise care.

    Behçet's disease is a multisystemic, chronic inflammatory disorder with diffuse clinical manifestations including the cardiovascular system. Endomyocardial fibrosis is a rarely seen complication of Behçet's disease leading to progressive heart failure. We report a case of right ventricular endomyocardial fibrosis mimicking Ebstein anomaly in a 26-year-old male Turkish patient with Behçet's disease, who had heart failure symptoms. In addition, the previously reported cases of endomyocardial fibrosis complicating Behçet's disease are reviewed in this article.

    As the population of adults with congenital heart disease continues to grow, so does the number of these patients with heart failure. Ventricular assist devices are underutilized in adults with congenital heart disease due to their complex anatomic arrangements and physiology. Advanced imaging techniques that may increase the utilization of mechanical circulatory support in this population must be explored. Three-dimensional printing offers individualized structural models that would enable pre-surgical planning of cannula and device placement in adults with congenital cardiac disease and heart failure who are candidates for such therapies. We present a review of relevant cardiac anomalies, cases in which such models could be utilized, and some background on the cost and procedure associated with this process.

  9. Fetal Aortic Arch Anomalies: Key Sonographic Views for Their Differential Diagnosis and Clinical Implications Using the Cardiovascular System Sonographic Evaluation Protocol.

    2016-02-01

    Aortic arch anomalies are present in 1% to 2% of the general population and are commonly associated with congenital heart disease, chromosomal defects, and tracheaesophageal compression in postnatal life. The sonographically based detection of aortic arch anomalies lies in the 3-vessel and trachea view. Although highly sensitive, this view alone does not allow identification of the aortic arch branching pattern, which prevents an accurate diagnosis. The systematic addition of a subclavian artery view as part of a standardized procedure may be useful in the differential diagnosis of these conditions. We describe the sonographic assessment of fetal aortic arch anomalies by combining 2 fetal transverse views: the 3-vessel and trachea view and the subclavian artery view, which are included in the cardiovascular system sonographic evaluation protocol. We also review the sonographic findings and the clinical implications of fetal aortic arch anomalies.

    In contrast to the sophisticated music processing reported in the general population, individuals with congenital amusia show deficits in music perception and production. Congenital amusia occurs without brain damage, sensory or cognitive deficits, and has been suggested as a lifelong deficit with genetic origin. Even though recognized for a long time, this disorder has been systematically studied only relatively recently for its behavioral and neural correlates. The currently most investigated hypothesis about the underlying deficits concerns the pitch dimension, notably with impaired pitch discrimination and memory. Anatomic and functional investigations of pitch processing revealed that the amusic brain presents abnormalities in the auditory and inferior frontal cortices, associated with decreased connectivity between these structures. The deficit also impairs processing of pitch in speech material and processing of the time dimension in music for some of the amusic individuals, but does not seem to affect spatial processing. Some studies suggest at least partial dissociation in the disorder between perception and production. Recent studies revealed spared implicit pitch perception in congenital amusia, supporting the power of implicit cognition in the music domain. Current challenges consist in defining different subtypes of congenital amusia as well as developing rehabilitation programs for this "musical handicap."

  14. A sign on CT that predicts a hazardous ureteral anomaly

    Introduction An aberrant course of the distal ureter can pose a risk of ureteral injury during surgery for inguinal hernia repair and other groin operations. In a recent case series of inguinoscrotal hernation of the ureter, we found that each affected ureter was markedly anterior to the psoas muscle at its mid-point on abdominal CT. We hypothesized that this abnormality in the abdominal course of the ureter would predict the potentially hazardous aberrant course of the distal ureter. Presentation of cases We reviewed all evaluable CT urograms performed at St. Louis University Hospital from June 2012 to July 2013 and measured the ureteral course at several anatomically fixed points. Discussion 93% (50/54) of ureters deviated by less than 1 cm from the psoas muscle in their mid-course (at the level of the L4 vertebra). Reasons for anterior deviation of the ureter in this study included morbid obesity with prominent retroperitoneal fat, congenital renal abnormality, and post-traumatic renal/retroperitoneal hematoma. We determined that the optimal level on abdominal CT to detect the displaced ureter was the mid-body of the L4 vertebra. Conclusion Anterior deviation of the ureter in its mid-course appears to predict inguinoscrotal herniation of the ureter. This finding is a sensitive predictor and should raise concern for this anomaly in the appropriate clinical setting. It is not entirely specific as morbid obesity and congenital anomalies may result in a similar imaging appearance. We believe that this association has not been reported previously. Awareness of this anomaly can have significant operative implications. PMID:27046105

    Congenital hearing loss occurs in association with cranio-facial anomalies. Lay people and health professionals as well frequently regard individuals with cranio-facial anomalies as "stupid" or of lower than normal intelligence because of their odd appearance. Two case reports illustrate that this erroneous assumption will result in the delayed detection of significant hearing loss.

  16. Echocardiographic assessment of Ebstein's anomaly.

    PubMed

    Booker, Oscar J; Nanda, Navin C

    2015-01-01

    Ebstein's anomaly is a complex congenital lesion which primarily involves the tricuspid valve. The tricuspid leaflets are tethered to varying degrees to the right ventricular free wall and the ventricular septum often resulting in significant tricuspid regurgitation and a small functioning right ventricular chamber. Although the septal leaflet originates normally at the right atrioventricular junction, the proximal portion is often completely tethered to the ventricular septum resulting in a misconception and erroneous statements in many publications that its attachment is apically displaced. Although two-dimensional echocardiography represents the primary modality for the diagnosis of this anomaly, three-dimensional echocardiography provides incremental value in characterizing the extent and severity of tethering of individual tricuspid valve leaflets. This information is useful in surgical decision making whether to repair or replace the tricuspid valve.

    Pulmonary vascular diseases of the newborn comprise a wide range of pathological conditions with developmental abnormalities in the pulmonary vasculature. Clinically, pulmonary arterial hypertension (PH) is characterized by persistent increased resistance of the vasculature and abnormal vascular response. The classification of PH is primarily based on clinical parameters instead of morphology and distinguishes five groups of PH. Congenital lung anomalies, such as alveolar capillary dysplasia (ACD) and PH associated with congenital diaphragmatic hernia (CDH), but also bronchopulmonary dysplasia (BPD), are classified in group three. Clearly, tight and correct regulation of pulmonary vascular development is crucial for normal lung development. Human and animal model systems have increased our knowledge and make it possible to identify and characterize affected pathways and study pivotal genes. Understanding of the normal development of the pulmonary vasculature will give new insights in the origin of the spectrum of rare diseases, such as CDH, ACD, and BPD, which render a significant clinical problem in neonatal intensive care units around the world. In this review, we describe normal pulmonary vascular development, and focus on four diseases of the newborn in which abnormal pulmonary vascular development play a critical role in morbidity and mortality. In the future perspective, we indicate the lines of research that seem to be very promising for elucidating the molecular pathways involved in the origin of congenital pulmonary vascular disease.

    The ears of 47 selected patients with congenital sensorineural hearing loss were examined with complex-motion tomography. The patients were divided into 3 general categories: those with a recognized syndrome, those with sensorineural hearing loss unrelated to any known syndrome, and those with microtia. A great variety of inner ear anomalies was detected, but rarely were these characteristic of a particular clinical entity. The most common finding was the Mondini malformation or one of its variants. Isolated dysplasia of the internal auditory canal or the vestibular aqueduct may be responsible for sensorineural hearing loss in some patients. Patients with microtia may also have severe inner ear abnormalities despite the fact that the outer and inner ears develop embryologically from completely separate systems.

    The microcephaly-lymphedema-chorioretinal dysplasia (MLCRD) syndrome is a distinct microcephaly syndrome. The hallmark features, microcephaly, chorioretinopathy, and lymphedema, are frequently recognized at birth. Another clinical entity, the chorioretinal dysplasia, microcephaly and mental retardation syndrome (CDMMR) is a highly overlapping syndrome characterized by more variable lymphedema. Recently, heterozygous mutations in KIF11, a gene encoding a critical spindle motor protein of the Kinesin family, have been reported in individuals with MLCRD, and in individuals with CDMMR. This finding is suggestive of a single clinically variable spectrum. Here, we report on de novo novel mutations of KIF11 in five individuals with severe microcephaly, marked simplification of the gyral pattern on neuroimaging, bilateral chorioretinopathy and developmental delay. Three patients had congenital lymphedema, and one had congenital bilateral sensorineural hearing loss. This report therefore further expands the clinical and molecular spectrum of KIF11-associated microcephaly. PMID:25115524

    As a whole the congenital defects constitute an important section of the medical attention affecting near 3% of the population. A 15% of spontaneous abortions take place of which the greater frequency corresponds to the chromosome anomalies (25%) and the monogenic mutations (20%) and in a lesser extent to the effects of teratogenic agents. Between the genetic causes determining the congenital defects the mutations that affect genes acting in the early stages of development occupy a main place. These alterations can affect to homeotic genes or monogenic systems that act during the critical phases of the organogenesis. It seems evident that an alteration in the expression of a necessary gene for the appearance of a morphogenetic change constitutes the angular stone to understand resurging of a malformation or discapacity. In the last years has been demonstrated the importance of the teratogenic or environmental agents on the delicate internal physiological balance during the critical stages of the development. In this context must be included the inductive environmental factors inducing epigenetic modifications in the early stage of the development of the embryos produced by fertilization in vitro.

  6. Why Search for Congenital Defects?

    PubMed Central

    Collins, John F.

    1966-01-01

    The causation of congenital malformation is receiving increased study. In Canada, epidemiologic surveys are being planned, based upon the institution of Provincial Registries to which physicians and other agencies will voluntarily report cases coming to their attention. The literature in regard to prevalence studies of congenital cardiac defects in school children is reviewed. Over the past 25 years, studies employing the proposed technique demonstrated a rising trend, from 1.4 per 1000 to 2.6 per 1000. By contrast, specific surveys for congenital cardiac defect carried out by expert personnel using radiographs and electrocardiographs, resulted in essentially uniform rates, approximating 5 to 6 per 1000. It is concluded that the latter is a superior technique of epidemiologic survey over the “Central Registry” method, and should command a due proportion of health resources directed towards congenital malformation research.

    Background Congenital midline cervical cleft (CMCC) is a rare developmental anomaly of the anterior neck, mostly found in Caucasian females. Most authors consider it within the spectrum of branchial arch developmental abnormalities. There have been about 100 reported cases in the literature. However, there is no agreement on the age of surgery in this anomaly. Case Presentation In this report we present our experience of managing this anomaly in the early neonatal period in two neonates. One of them had concomitantly congenital heart disease. Conclusion It is important to recognize this rare congenital anomaly in neonate. Although the exact time of surgery for CMCC is not mentioned, based on our results the earliest time of intervention is recommended since then the operating result will be excellent. PMID:23431110

    In this report, we describe the esophageal atresia in terms of current surgical management on the basis of our experience and literatures. Traditionally, infants with esophageal atresia have presented shortly after birth because of an inability to pass an orogastric tube, respiratory distress, or an inability to tolerate feeding. And also, an isolated trachea-esophageal fistula (TEF) usually cases coughing, recurrent pneumonia, or choking during feedings. To ignore these symptoms is to risk a delayed diagnosis. The condition may be associated with other major congenital anomalies such as those seen in the vertebral, anal, cardiac, tracheo-esophageal, renal/radial (VACTER) association, or it may be an isolated defect. Therapeutic strategies for esophageal atresia are a prevention of pulmonary complication by TEF closing and an early establishment of enteral alimentation. We promptly repair healthy infants without performing a gastrostomy and delay repair in infants with high-risk factors such as associated severe cardiac anomaly and respiratory insufficiency. Esophageal atresia has been classically approached through a thoracotomy. The disadvantages of such a thoracotomy have been recognized for a long time, for example winged scapula, elevation of fixation of shoulder, asymmetry of the chest wall, rib fusion, scoliosis, and breast and pectoral muscle maldevelopment. To avoid such disadvantages, thoracoscopic repair was recently reported.

    A systematic review of English and non-English language articles on the complications of mandibular distraction osteogenesis (MDO) for patients with congenital deformities was performed, in accordance with the PRISMA statement. Search terms expressing distraction osteogenesis were used in 'AND' combination with search terms comprising 'mandible' and terms for complication, failure, and morbidity. A search using PubMed (National Library of Medicine, NCBI), EMBASE, and the Cochrane Central Register of Controlled Trials yielded 644 articles published between 1966 and mid October 2013. Clinical articles that reported complications related to MDO were included. Finally 81 articles on MDO in congenital deformities were eligible and were screened in detail. Complications including minor infection (6.0%), device-related problems (7.3%), skeletal open bite (2.4%), hypertrophic scar formation (2.1%), facial nerve palsy (1.8%), neurosensory disturbances of the inferior alveolar nerve (1.9%), and (fibrous) non-union (0.7%) were seen. A new index for more detailed classification of complications in MDO is proposed based on six categories that indicate the impact of the complication and its further treatment or final results. The proposed complication index may be a useful tool to classify complications related to MDO.

    Congenital diaphragmatic hernia (CDH) occurs in 1 in 3,000 newborns. Mortality and morbidity are due to the amount of pulmonary hypoplasia (PH), the response on artificial ventilation and the presence of therapy-resistant pulmonary hypertension. The pathogenesis and etiology of CDH and its associated anomalies are still largely unknown despite all research efforts over the past years. Several animal models have been proposed to study CDH. In this review we compare surgical, pharmacological and transgenic models, and discuss their strengths and limitations to study PH.

She exhibited, among other features, psychomotor retardation, congenital severe bilateral glaucoma, a cleft palate, and heart defect. Microarray assay disclosed a deleted 12.5-Mb region roughly 88 kb downstream the ectrodactyly critical region; thus, the patient's final karyotype was 46,XX.arr 7q21.3q31.1(96,742,140-109,246,085)×1 dn. This girl represents the fourth patient described so far with congenital glaucoma and a deletion encompassing or overlapping the 7q21.3q31.1 region, and confirms the presence of a locus or loci related to such a clinical feature. According to our results, the proneness to ocular defects secondary to 7q intermediate deletions could be caused by co-deletion of TAC1, HBP1, and a small cluster of cytochrome P450 genes (subfamily 3A). This conclusion is supported by their functional roles and expression locations as well as because TAC1 is related to the functional pathway of the MYOC gene whose mutations are linked to glaucoma. Moreover, given that this girl is clinically reminiscent of several phenotypes related to diverse deletions within 7q21q32, our results and observations offer a general overview of the gene content of deletions/phenotypes overlapping 7q21.3q31.1 and confirm that loci distal to DLX genes including the CUX1 gene and potential regulatory elements downstream from DLX5 are unrelated to ectrodactyly.

    A female child born preterm with intrauterine growth retardation and presenting with facial dysmorphism with clefts, microcephaly, limb deformities, and congenital abnormalities involving cardiovascular and urinary systems is described. Chromosomal analysis showed a de novo 46,XX,r(4)(p15.3q35) karyotype. The clinical features of the patient were compared with the phenotypic characteristics of 17 previously reported cases with ring chromosome 4 and those with Wolf-Hirschhorn syndrome (4p-). Clinical features observed in this case are consistent with the consensus phenotype in ring chromosome 4. Patent ductus arteriosus and bilateral talipes equinovarus observed in this baby widen the phenotypic spectrum associated with ring chromosome 4.

  17. Classification of congenital nasal deformities: a proposal to amend the existing classification.

    Congenital nasal anomalies are rare malformations with a broad spectrum of defects. The only existing classification strictly relating to nasal anomalies was presented by Losee et al. (Plast Reconstr Surg 113(2):676-689, 2004). The aim of this paper is to propose some suggestions, based on our current knowledge and experience gained by treating our patients in the clinic, in creating a specification of patients with congenital nasal anomalies. All patients with congenital nose defects treated in our health center were selected for this study. The research was retrospective and included years from 1995 to 2015. Nasal anomaly associated with cleft lip and palate was excluded. Patients were classified into four categories of congenital nasal anomalies, according to Losee et al.

    Congenital adrenal agenesis is an extremely rare condition wherein the adrenal glands fail to develop. The absence of adrenal tissue results in the complete absence of hormones produced in the adrenal cortex (cortisol, aldosterone) and medulla (catecholamines), and is not compatible with postnatal life without artificial hormone replacement therapy. To date, 9 cases of adrenal agenesis have been reported, many of which are associated with additional congenital anomalies. Most cases were not detected on antenatal imaging and were detected incidentally at postmortem examination. We present a case of adrenal agenesis, detected incidentally at postmortem examination after termination of pregnancy for suspected fetal hydrops, and review the heterogeneous phenotype of this condition with associated abnormalities and molecular genetics. This case reinforces the role of the perinatal autopsy to investigate cause of perinatal mortality, allowing correlation of pathology with antenatal imaging findings and clinical details.

    Disruption in early pregnancy can cause severe and multiple congenital anomalies in a foetus. Three sequences, Limb-body wall complex (LBWC), amniotic band sequence (ABS) and body-stalk anomaly (BSA) are thought to be caused by disruption. This case report describes a foetus with severe multiple congenital anomalies, that fit the diagnoses of all three sequences, which might advocate these syndromes are a spectrum of one sequence.

    Mutations in ABCA12 have been described in autosomal recessive congenital ichthyoses (ARCI) including harlequin ichthyosis (HI), congenital ichthyosiform erythroderma (CIE), and lamellar ichthyosis (LI). HI shows the most severe phenotype. CIE and LI are clinically characterized by fine, whitish scales on a background of erythematous skin, and large, thick, dark scales over the entire body without serious background erythroderma, respectively. To date, a total of 56 ABCA12 mutations have been reported in 66 ARCI families including 48 HI, 10 LI, and 8 CIE families of African, European, Pakistani/Indian, and Japanese origin (online database: http://www.derm-hokudai.jp/ABCA12/). A total of 62.5% of reported ABCA12 mutations are expected to lead to truncated proteins. Most mutations in HI are truncation mutations and homozygous or compound heterozygous truncation mutations always results in HI phenotype. In CIE families, at least one mutation on each allele is typically a missense mutation. Combinations of missense mutations in the first ATP-binding cassette of ABCA12 underlie the LI phenotype. ABCA12 is a keratinocyte lipid transporter associated with lipid transport in lamellar granules, and loss of ABCA12 function leads to a defective lipid barrier in the stratum corneum, resulting in an ichthyotic phenotype. Recent work using mouse models confirmed ABCA12 roles in skin barrier formation.

    At the beginning of the Medieval Climate Anomaly, in the ninth and tenth century, the medieval eastern Roman empire, more usually known as Byzantium, was recovering from its early medieval crisis and experiencing favourable climatic conditions for the agricultural and demographic growth. Although in the Balkans and Anatolia such favourable climate conditions were prevalent during the eleventh century, parts of the imperial territories were facing significant challenges as a result of external political/military pressure. The apogee of medieval Byzantine socio-economic development, around AD 1150, coincides with a period of adverse climatic conditions for its economy, so it becomes obvious that the winter dryness and high climate variability at this time did not hinder Byzantine society and economy from achieving that level of expansion. Soon after this peak, towards the end of the twelfth century, the populations of the Byzantine world were experiencing unusual climatic conditions with marked dryness and cooler phases. The weakened Byzantine socio-political system must have contributed to the events leading to the fall of Constantinople in AD 1204 and the sack of the city. The final collapse of the Byzantine political control over western Anatolia took place half century later, thus contemporaneous with the strong cooling effect after a tropical volcanic eruption in AD 1257. We suggest that, regardless of a range of other influential factors, climate change was also an important contributing factor to the socio-economic changes that took place in Byzantium during the Medieval Climate Anomaly. Crucially, therefore, while the relatively sophisticated and complex Byzantine society was certainly influenced by climatic conditions, and while it nevertheless displayed a significant degree of resilience, external pressures as well as tensions within the Byzantine society more broadly contributed to an increasing vulnerability in respect of climate impacts.

    Ebstein anomaly is a rare congenital disorder that involves the tricuspid valve and the right ventricle. It is associated with interatrial communication, which allows for paradoxical embolization causing unilateral blindness. Abnormal conduction through the atrialized right ventricle leads to QRS fragmentation on electrocardiogram. Its presence suggests a more severe abnormality and a higher risk of arrhythmia. The QRS fragmentation disappears after corrective surgery with resection of the atrialized right ventricle. PMID:28203575

    An independent variable different from the time for elliptic orbit integration is used. Such a time transformation provides an analytical step-size regulation along the orbit. An intermediate anomaly (an anomaly intermediate between the eccentric and the true anomaly) is suggested for optimum performances. A particular case of an intermediate anomaly (the elliptic anomaly) is defined, and its relation with the other anomalies is developed.

    2014-03-01

    Lower urinary tract and/or kidney malformations are collectively the most common cause of end-stage renal disease in children, and they are also likely to account for a major subset of young adults requiring renal replacement therapy. Advances have been made regarding the discovery of the genetic causes of human kidney malformations. Indeed, testing for mutations of key nephrogenesis genes is now feasible for patients seen in nephrology clinics. Unfortunately, less is known about defined genetic bases of human lower urinary tract anomalies. The focus of this review is the genetic bases of congenital structural and functional disorders of the urinary bladder. Three are highlighted. First, prune belly syndrome, where mutations of CHRM3, encoding an acetylcholine receptor, HNF1B, encoding a transcription factor, and ACTA2, encoding a cytoskeletal protein, have been reported. Second, the urofacial syndrome, where mutations of LRIG2 and HPSE2, encoding proteins localised in nerves invading the fetal bladder, have been defined. Finally, we review emerging evidence that bladder exstrophy may have genetic bases, including variants in the TP63 promoter. These genetic discoveries provide a new perspective on a group of otherwise poorly understood diseases.

  7. Congenital Toxoplasmosis

    2014-01-01

    Toxoplasmosis is caused by infection with the parasite Toxoplasma gondii. It is one of the most common parasitic infections in humans and is most typically asymptomatic. However, primary infection in a pregnant woman can cause severe and disabling disease in the developing fetus. Recent developments have included increased understanding of the role of parasite genotype in determining infectivity and disease severity. Risk factors for acquisition of infection have been better defined, and the important role of foodborne transmission has been further delineated. In addition, strategies have emerged to decrease mother-to-child transmission through prompt identification of acutely infected pregnant women followed by appropriate treatment. Refined diagnostic tools, particularly the addition of immunoglobulin G avidity testing, allow for more accurate timing of maternal infection and hence better decision making during pregnancy. Congenitally infected children can be treated, beginning in utero and continuing through the first year of life, to ameliorate the severity of disease. However, despite these many advances in our understanding of congenital toxoplasmosis prevention and treatment, significant areas of study remain: we need better drugs, well defined strategies for screening of pregnant women, improved food safety, and improved diagnostic tests.

    The combination of Turner syndrome with other genetic disorders such as congenital cataract has been reported, but its association with a congenital form with autosomal dominant inheritance and incomplete penetrance has not been previously reported in the literature. There are no reports on its presentations with rearrangements on chromosome 17. We report the exceptional case of a 20 months old girl with a constellation of major and minor anomalies, diagnosed with mosaic Turner syndrome by isochromosome Xq associated with a microduplication 17p13.3p13.2, who also had bilateral congenital nuclear cataract autosomal dominant with incomplete penetrance. We reviewed in the literature the origin and cause of these genetic alterations and we provided an approach to the hypothesis of the pathogenesis of the association of two of these genetic disorders in the same patient.

    Congenital rubella infection has been associated with a number of abnormalities including cardiac, central nervous system and placental complications. We present a case with multiple fetal abnormalities detected on prenatal ultrasound, and confirmed postnatally, that included a single umbilical artery, severe tricuspid regurgitation, micrognathia and agenesis of the inferior cerebellar vermis. Postnatal echocardiography additionally revealed unobstructed total anomalous pulmonary venous drainage (TAPVD) into the coronary sinus. Placental examination showed signs of placentitis, and polymerase chain reaction on neonatal serum was positive for rubella. Following a multidisciplinary team review, it was decided to provide only supportive care, and the infant died at 6 months of age owing to a respiratory tract infection. To our knowledge, TAPVD and agenesis of the inferior cerebellar vermis have not been reported previously in association with congenital rubella infection. This case illustrates how congenital infection may present in atypical ways and stresses the importance of considering congenital infection in the differential diagnosis of fetal anomalies when multiple features are present.

    2003-01-01

    On-orbit anomaly records for satellites launched from 1990 through 2001 are reviewed to determine recent trends of un-manned space mission critical failures. Anomalies categorized by subsystems show that Guidance, Navigation and Control (GN&C) subsystems have a high number of anomalies that result in a mission critical failure when compared to other subsystems. A mission critical failure is defined as a premature loss of a satellite or loss of its ability to perform its primary mission during its design life. The majority of anomalies are shown to occur early in the mission, usually within one year from launch. GN&C anomalies are categorized by cause and equipment type involved. A statistical analysis of the data is presented for all anomalies compared with the GN&C anomalies for various mission types, orbits and time periods. Conclusions and recommendations are presented for improving mission success and reliability.

    Spinal neurenteric (NE) cysts are rare congenital anomalies that may occur either alone or in the context of a complex malformative disorder. They are usually intradural-extramedullary lesions. Intramedullary NE cysts not associated with other congenital anomalies are very rare and only a few cases have been reported in the conus medullaris region. Intramedullary neurenteric cysts not associated with other spinal anomalies are very rare especially in the conus medullaris region. MRI is useful to define the cyst and the osseous anomalies associated with this lesion. The goal of treatment of an intramedullary neurenteric cyst is total excision at the first operation, if possible. Life-long follow-up with annual MRI is recommended due to the risk of cyst recurrence. We report an intramedullary NE cyst of the conus medullaris without associated malformation and the relevant literature is briefly reviewed.

    Lymphatic malformations (LMs) are congenital lymphatic lesions that impose significant and costly morbidities on affected patients. Treatment options are limited due to incomplete understanding of LM pathobiology. Expression of an activated β2-adrenergic receptor has been described in LM tissue, suggesting that this pathway may contribute to the clinical manifestations of LM. We hypothesized that propranolol, a β-adrenergic receptor antagonist, might improve symptoms of patients with LMs and lymphatic anomalies. A retrospective chart review of patients treated with propranolol as an adjunct therapy was conducted; analyses included demographic characteristics, clinical features, and response to propranolol. Three patients with cystic and noncystic LMs displayed clinical improvement at a minimum dose of 0.7 mg/kg/d, whereas symptomatic relapses were observed when propranolol doses dropped below this threshold. Two patients with Klippel-Trenaunay syndrome demonstrated partial clinical responses with reduced edema. The fetus of a mother treated with propranolol from a gestational age of 35 weeks through delivery displayed arrested growth of a cervicofacial LM. Our retrospective review suggests that propranolol improved symptoms in a subset of patients with lymphatic anomalies. Propranolol treatment may also limit the growth of congenital LMs in utero.

  14. Performance of Polymerase Chain Reaction Analysis of the Amniotic Fluid of Pregnant Women for Diagnosis of Congenital Toxoplasmosis: A Systematic Review and Meta-Analysis

    PubMed Central

    2016-01-01

    Introduction Congenital infection caused by Toxoplasma gondii can cause serious damage that can be diagnosed in utero or at birth, although most infants are asymptomatic at birth. Prenatal diagnosis of congenital toxoplasmosis considerably improves the prognosis and outcome for infected infants. For this reason, an assay for the quick, sensitive, and safe diagnosis of fetal toxoplasmosis is desirable. Goal To systematically review the performance of polymerase chain reaction (PCR) analysis of the amniotic fluid of pregnant women with recent serological toxoplasmosis diagnoses for the diagnosis of fetal toxoplasmosis. Method A systematic literature review was conducted via a search of electronic databases; the literature included primary studies of the diagnostic accuracy of PCR analysis of amniotic fluid from pregnant women who seroconverted during pregnancy. The PCR test was compared to a gold standard for diagnosis. Results A total of 1.269 summaries were obtained from the electronic database and reviewed, and 20 studies, comprising 4.171 samples, met the established inclusion criteria and were included in the review. The following results were obtained: studies about PCR assays for fetal toxoplasmosis are generally susceptible to bias; reports of the tests’ use lack critical information; the protocols varied among studies; the heterogeneity among studies was concentrated in the tests’ sensitivity; there was evidence that the sensitivity of the tests increases with time, as represented by the trimester; and there was more heterogeneity among studies in which there was more time between maternal diagnosis and fetal testing. The sensitivity of the method, if performed up to five weeks after maternal diagnosis, was 87% and specificity was 99%. Conclusion The global sensitivity heterogeneity of the PCR test in this review was 66.5% (I2). The tests show low evidence of heterogeneity with a sensitivity of 87% and specificity of 99% when performed up to five weeks

    A case of congenital glaucoma in cutis marmorata teleangiectatica congenita (CMTC, van Lohuizen syndrome) is described. The cutaneous anomaly and heterochromia iridium were noticed at birth. Brown discoloration of one iris was due to iris anterior layer dysplasia, resulting in unilateral glaucoma. Two trabeculotomies were performed until persistent normalization of intraocular pressure could be achieved. The possibility of a genetic basis and hereditary condition of CMTC and its association with congenital glaucoma is discussed. Patients with CMTC should regularly undergo ophthalmological follow-up to rule out development of glaucoma.

    We report three cases of congenital absence of an internal carotid artery (ICA), diagnosed incidentally by digital subtraction angiography. The analysis of the cases is based on the classification of segmental ICA agenesis proposed by Lasjaunias and Berenstein. Usually the patients with this rare vascular anomaly are asymptomatic; some may have symptoms related to cerebrovascular insufficiency, compression by enlarged intracranial collateral vessels, or complications associated with cerebral aneurysms. Diagnosis of congenital absence of ICA is made by skull base computed tomography (CT) scan, CT and magnetic resonance angiography, and conventional or digital subtraction angiography.

    Ebstein's anomaly is a rare form of congenital malformation of the heart, characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialisation of the right ventricle with a variable degree of malformation and displacement of the anterior leaflet. It may not be detected until late in adolescence or adulthood. The clinical manifestations of Ebstein's anomaly vary greatly. We are reporting a case of 35-year male who presented with generalized fatigue, palpitation and effort intolerance. Laboratory investigations confirmed the diagnosis of diabetes ketosis. Transthoracic echocardiography showed severe Ebstein's anomaly with severe tricuspid regurgitation, no residual atrial septal defect, but with severe right ventricular dysfunction. Though only few studies showed the high prevalence of abnormal glucose metabolism in young adult patients with complex congenital heart disease, but Epstein's anomaly with diabetes ketosis was nowhere mentioned.

    Congenital granular cell tumors (CGCTs), which are rare benign lesions in newborns, locate predominantly on the anterior maxillary alveolar ridge of female neonates. However, this lesion rarely occurs on the tongue, and only 9 cases have been reported in the English literature. Of the 9 cases, which have been tested for S-100 protein, 4 were immunonegative to S-100 protein. In this present case, we reported a rare case of a 4-day-old Chinese girl with a CGCT on the anterior dorsum of the tongue. The lesion was excised under general anesthesia when the newborn was 3 months old. Histologically, pseudoepitheliomatous hyperplasia of the overlying mucosa was noted in this lesion. Immunohistochemical stains showed that the granular cells were diffusely strongly positive to S-100 protein, neuron-specific enolase, and vimentin. Depending on these findings, it was diagnosed as CGCT.

    Congenital self-healing reticulohistiocytosis, also known as Hashimoto-Pritzker disease, is a single system Langerhans cell histiocytosis that typically presents in healthy newborns and spontaneously regresses. In the present report, we described a 2-month-old Thai female newborn with multiple hypopigmented flat-topped papules without any internal organ involvement including normal blood cell count, urinary examination, liver and renal functions, bone scan, chest X-ray, abdominal ultrasound, and bone marrow biopsy. The histopathology revealed typical findings of Langerhans cell histiocytosis, which was confirmed by the immunohistochemical staining CDla and S100. Our patient's lesions had spontaneously regressed within afew months, and no new lesion recurred afterfour months follow-up.

    Objective To identify and synthesise the evidence on the relationship between surgical volume and patient outcomes for adults and children with congenital heart disease. Design Evidence synthesis of interventional and observational studies. Data sources MEDLINE, EMBASE, CINAHL, Cochrane Library and Web of Science (2009–2014) and citation searching, reference lists and recommendations from stakeholders (2003–2014) were used to identify evidence. Study selection Quantitative observational and interventional studies with information on volume of surgical procedures and patient outcomes were included. Results 31 of the 34 papers identified (91.2%) included only paediatric patients. 25 (73.5%) investigated the relationship between volume and mortality, 7 (20.6%) mortality and other outcomes and 2 (5.9%) non-mortality outcomes only. 88.2% were from the US, 97% were multicentre studies and all were retrospective observational studies. 20 studies (58.8%) included all congenital heart disease conditions and 14 (41.2%) single conditions or procedures. No UK studies were identified. Most studies showed a relationship between volume and outcome but this relationship was not consistent. The relationship was stronger for single complex conditions or procedures. We found limited evidence about the impact of volume on non-mortality outcomes. A mixed picture emerged revealing a range of factors, in addition to volume, that influence outcome including condition severity, individual centre and surgeon effects and clinical advances over time. Conclusions The heterogeneity of findings from observational studies suggests that, while a relationship between volume and outcome exists, this is unlikely to be a simple, independent and directly causal relationship. The effect of volume on outcome relative to the effect of other, as yet undetermined, health system factors remains a complex and unresolved research question. PMID:26685029

    A link between congenital vascular malformation (CVM) of the liver and trisomy 21 has been suggested. We reviewed all children with trisomy 21 referred for investigation to a specialist pediatric hepatobiliary unit (1985-2015). Forty-five children with trisomy 21 were identified; 7 (15%) had a defined CVMs (4 girls). All such infants were also diagnosed with a range of cardiac defects. CVMs were divided according to the nature of the vascular connection. Group (i) (n = 3): Abnormal venovenous anomaly. This included portocaval shunt and patent ductus venosus (n = 2). Group (ii) (n = 4): Involvement of all 3 vascular systems. Two infants had arterioportal hypertension caused by hepatic arteries feeding into a left portal vein aneurysm within the umbilical fissure. Two infants had more complex hepatic artery to hepatic vein shunts developing early cardiorespiratory failure with progressive jaundice. Our series shows a clear association between cardiac anomalies and CVM in children with trisomy 21.

    Numerous malformations can affect the anterior part of the neck presenting at birth as a real diagnostic challenge for the pediatrician or the primary care physician who initially evaluate the baby. Congenital midline cervical cleft represents a rare defect of the midline neck, which is sometimes wrongly diagnosed as a thyroglossal duct anomaly, dermoid cyst, branchial cleft anomaly or "birthmark". A prompt clinical diagnosis and surgical treatment during early infancy are essential to ensure both functional and aesthetic outcome. We report a case of a female neonate with a midline cervical cleft diagnosed immediately after birth. The main features of other congenital anomalies of the anterior neck are also discussed referring to their embryologic origin.

    Offspring of women with anti-SSA/Ro-SSB/La antibodies are believed to be at risk for congenital heart block (CHB). Whether this risk can be reduced, and what constitutes standard of care treatment is, however, unclear. The objective of this review therefore was to determine whether currently proposed standard of care treatments to avoid CHB in offspring of mothers at risk are evidence-based. To do so, we conducted a review of the literature under appropriate keywords and phrases in Medline/PubMed and Google Scholar for the years 2000-2013. Reference lists were further reviewed, and relevant manuscripts were pulled. We also reviewed www.clinicaltrials.gov for registered studies. In the absence of randomized prospective clinical trials, a meta-analysis was not feasible. We, therefore, reviewed lower evidence level studies individually. Risk of CHB actually appears more closely associated with general autoimmunity than, specifically, with SSA/Ro-SSB/La antibodies. This and other observations raise questions whether CHB is caused by passively transferred maternal autoimmunity, as is currently widely believed. Observational studies suggest the possible effectiveness of intravenous gamma globulin (IV-Ig) and hydroxychloroquine (Plaquenil) in reducing CHB-risk. Evidence for both is, however, inconclusive, and studies are biased in favor of hydroxychloroquine and against IV-Ig. Based on the review of the literature, current evidence of effectiveness for any treatment has to be judged as insufficient. Among the available treatment options, some considerations favor IV-Ig over hydroxychloroquine or, alternatively, suggest treatment with IV-Ig periconceptionally and into early gestation, with hydroxychloroquine added or replacing IV-Ig at approximately 10weeks gestational age. Benefits for the utilization of steroid drugs are unclear. Since no treatment can be considered as established, prevention of CHB in offspring should be considered experimental, and performed under

    Glycosylation is an essential process by which sugars are attached to proteins and lipids. Complete lack of glycosylation is not compatible with life. Because of the widespread function of glycosylation, inherited disorders of glycosylation are multisystemic. Since the identification of the first defect on N-linked glycosylation in the 1980s, there are over 40 different congenital protein hypoglycosylation diseases. This review will include defects of N-linked glycosylation, O-linked glycosylation and disorders of combined N- and O-linked glycosylation. PMID:23776380

    Congenital heart disease is the most common congenital disorder in newborns. Advances in cardiovascular medicine and surgery have enabled most patients to reach adulthood. Unfortunately, prolonged survival has been achieved at a cost, as many patients suffer late complications, of which heart failure and arrhythmias are the most prominent. Accordingly, these patients need frequent follow-up by physicians with specific knowledge in the field of congenital heart disease. However, planning of care for this population is difficult, because the number of patients currently living with congenital heart disease is difficult to measure. Birth prevalence estimates vary widely according to different studies, and survival rates have not been well recorded. Consequently, the prevalence of congenital heart disease is unclear, with estimates exceeding the number of patients currently seen in cardiology clinics. New developments continue to influence the size of the population of patients with congenital heart disease. Prenatal screening has led to increased rates of termination of pregnancy. Improved management of complications has changed the time and mode of death caused by congenital heart disease. Several genetic and environmental factors have been shown to be involved in the etiology of congenital heart disease, although this knowledge has not yet led to the implementation of preventative measures. In this Review, we give an overview of the etiology, birth prevalence, current prevalence, mortality, and complications of congenital heart disease.

    The Congenital Heart Surgeons' Society is a group of over 100 pediatric heart surgeons representing 72 institutions that specialize in the treatment of patients with congenital heart defects. The Society began in 1972 and incorporated as a not-for-profit charitable organization in 2004. It has become the face and voice of congenital heart surgery in North America. In 1985, the Society established a data center for multicenter clinical research studies to encourage congenital heart professionals to participate in improving outcomes for our patients. The goals of the Congenital Heart Surgeons' Society are to stimulate the study of congenital cardiac physiology, pathology, and management options which are instantiated in data collection, multi-institutional studies, and scientific meetings. Honest and open discussion of problems with possible solutions to the challenges facing congenital heart professionals have been the strength of the Congenital Heart Surgeons' Society. It is imperative for the growth of an organization to know from where it came in order to know to where it is going. The purpose of this article is to review the history of the Congenital Heart Surgeons' Society.

    Background. Congenital anomalies of the coronary arteries are a cause of sudden cardiac death. Of the known anatomic variants, anomalous origination of a coronary artery from an opposite sinus of Valsalva (ACAOS) remains the main focus of debate. Case Series. We present three cases, all presenting to our facility within one week's time, of patients with newly discovered anomalous origination of the left coronary artery from the right sinus of Valsalva (L-ACAOS). All patients underwent cardiac computed tomography for evaluation of coronary anatomy along with other forms of functional testing. Despite the high risk nature of two of the anomalies, the patients are being treated medically without recurrence of symptoms. Summary. After review of the literature, we have found that the risk of sudden cardiac death in patients with congenital coronary anomalies, even among variants considered the highest risk, may be overestimated. In addition, the exact prevalence of coronary anomalies in the general population is currently underestimated. A national coronary artery anomaly registry based on cardiac computed tomography and invasive coronary angiography data would be helpful in advancing our understanding of these cardiac peculiarities. The true prevalence of congenital coronary anomalies and overall risk of sudden cardiac death in this population are not well known. Surgical intervention remains the mainstay of therapy in certain patients though recent investigations into the pathophysiology of these abnormalities have shown that the risk of surgery may outweigh the minimal reduction in risk of sudden cardiac death.

    Leber's congenital amaurosis (LCA) is a clinically and genetically heterogeneous disorder characterized by severe loss of vision at birth. It accounts for 10-18% of cases of congenital blindness. Some patients exhibit only blindness of retinal origin whereas others show evidence of a multi-systemic involvement. We review the literature relating to this severe disorder, highlighting unresolved questions, in particular the nature of the association of LCA with mental retardation and with systemic findings and syndromic pictures. In recent years, genetic advances in the diagnosis of LCA have opened up new horizons, also from a therapeutic point of view. A better understanding of this pathology would be valuable for paediatric neurologists.

    Congenital insensitivity to pain and anhidrosis (CIPA) is one of the hereditary autonomic and sensory neuropathies. Typically presenting in infancy, it manifests as hyperpyrexia from defects in sweating (autonomic) and self-mutilating injuries from pain insensitivity (sensory). CIPA being rare in North America, diagnosis is often missed due to variable presentation. Subsequent management of its complications is therefore delayed. We report an unusual presentation in a 2-year-old girl with preexisting diagnosis of CIPA who was evaluated for bilateral upper extremity paresis of insidious onset. MRI revealed a mass compressing her cervical spine as the cause, and work up suggested immune dysfunction as possible etiology. To our knowledge, this complication has not been reported before in association with the disease. We introduce the disease by explaining the molecular pathology behind its presenting features. The neurological findings, documented in association with CIPA, are summarized and serve as a reference for the various presentations of this rare disorder. Since this disease is known to affect the immune system, immune defects in CIPA are discussed with recommendations for surveillance of patient's immune status.

    The increased survival rate reached in infants with congenital diaphragmatic hernia (CDH) has shown a concomitant increase in late morbidity. Many complications including pulmonary damage, cardiovascular disease, gastro-intestinal disease, failure to thrive, neurocognitive defects and musculoskeletal abnormalities have been described. Long-term pulmonary morbidity in CDH consists of obstructive and restrictive lung function impairments due to altered lung structure and prolonged ventilatory support. Long-term consequences of pulmonary hypertension are unknown. Gastro-esophageal reflux disease (GERD) is also an important contributor to overall morbidity. Failure to thrive may be caused by GERD, insufficient intake due to oral aversion and increased caloric requirements due to pulmonary morbidity. Neurological outcome is determined by an increased risk of perinatal and neonatal hypoxemia in the first days of life of CDH patients. Many studies have addressed the substantial impact of the health problems described above, on the overall well-being of CDH patients, but only a few studies focus on the health-related quality of life. Considering the scattered data indicating substantial morbidity in long-term survivors of CDH, follow-up studies that systematically assess long-term sequelae are needed. Based on such studies, a more focused approach for routine multidisciplinary follow-up programs could be established. It is the goal of the French Collaborative Network to promote exchange of knowledge, future research and development of treatment protocols.

    Neonatal liver failure (NLF) is a major cause of neonatal morbidity and mortality, presenting as acute liver failure and/or congenital cirrhosis. Many affected patients show antenatal signs of fetal injury. There are several causes of NLF and early diagnosis is mandatory to elucidate the etiology and determine a specific treatment or the best management strategy. Gestational alloimmune liver disease associated with neonatal hemochromatosis (GALD-NH) is a rare but potentially treatable cause of NLF. It should be considered in any neonate with fetal signs of disease and postnatal signs of liver failure with no other identifiable causes. GALD-NH is often diagnosed late and patients are therefore referred late to specialized centers, delaying treatment. This case highlights the consequences of late diagnosis and treatment of GALD-NH and emphasizes the importance of a high grade of suspicion of this disease in order to refer the patient to a specialized center soon enough to perform the appropriate treatment.

    Introduction. Congenital portosystemic venous malformations are rare abnormalities in which the portal blood drains into a systemic vein and which are characterized by extreme clinical variability. Case Presentations. The authors present two case reports of a congenital extrahepatic portosystemic shunt (Type II). In the first patient, apparently nonspecific symptoms, such as headache and fatigue, proved to be secondary to hypoglycemic episodes related to the presence of a portosystemic shunt, later confirmed on imaging. During portal vein angiography, endovascular embolization of the portocaval fistula achieved occlusion of the anomalous venous tract. In the second patient, affected by Down's syndrome, the diagnosis of a portosystemic malformation was made by routine ultrasonography, performed to rule out concurrent congenital anomalies. Because of the absence of symptoms, we chose to observe this patient. Conclusions. These two case reports demonstrate the clinical heterogeneity of this malformation and the need for a multidisciplinary approach. As part of a proper workup, clinical evaluation must always be followed by radiographic diagnosis. PMID:25709849

    Three patients who had a diagnosis of congenitally absent lumbar pedicle underwent CT examination. Findings showed that each patient had an aberrant hypoplastic pedicle plus a retroisthmic defect in their ipsilateral lamina rather than an absent pedicle. Axial CT was the diagnostic modality of choice; reformated images were of little value. The differential diagnosis to be considered from the findings of plain film radiography includes pediculate thinning, neoplastic disease, neurofibroma, mesodermal dysplasia associated with neurofibromatosis, and vascular anomalies.

    The spectrum of congenital heart disease (CHD) seen in the adult varies widely. Malformations range from mild anomalies requiring no intervention to extremely complex pathologies characterized by the presence of multiple coexistent defects. Echocardiography represents the primary noninvasive imaging modality in the assessment of these lesions. The transesophageal approach expands the applications of echocardiography by allowing the acquisition of anatomic and functional information that may not be obtainable by transthoracic imaging.
