Sample records for congenital vertebral malformations

  1. Pediatric congenital vertebral artery arteriovenous malformation

    International Nuclear Information System (INIS)

    Vertebral arteriovenous fistulas are rare in children and the congenital form has been seldom reported in the literature. Prior to using endovascular therapy techniques, only surgery was the main treatment. The most common endovascular treatment is through the use of detachable balloons. This report describes the clinical and radiological findings of a congenital vertebral artery fistula in a 20-month-old child. Balloons could not be safely employed; therefore, embolization was performed with Guglielmi detachable microcoils. We review the history and treatment of these lesions, their clinical presentation, and imaging features, including their outcome, with particular attention to the pediatric population. (orig.)

    Abstract Background Prior investigations have not identified a major locus for vertebral malformations, providing evidence that there is genetic heterogeneity for this condition. WNT3A has recently been identified as a negative regulator of Notch signaling and somitogenesis. Mice with mutations in Wnt3a develop caudal vertebral malformations. Because congenital vertebral malformations represent a sporadic occurrence, linkage approaches to identify genes associated with human vertebral develop...

    Articular process anomalies are considered congenital. Their occurrence in specific breeds may be indicative of undetermined genetics. Clinical significance varies and is interdependent upon location, function and anatomy. Etiology, uniform nomenclature and classification of vertebral articular process anomalies in the dog are lacking; however recent efforts are beginning to address this deficit. This author proposes that the term articular process dysplasia appropriately encompasses the spectrum of anomalies in severity as well as including those affecting both the cranial and caudal articular processes. The general category description of articular process dypslasia doesn't preclude, but rather allows for more specific designations. PMID:26851714

    Congenital malformations of the thoracic vertebral bodies are commonly encountered in veterinary practice. These anomalies are prevalent in juvenile and adult small-breed dogs. These anomalous vertebrae typically result in various degrees of kyphosis and scoliosis in the region of the abnormality. They are thought to occur following developmental errors during embryonic or fetal vertebral segmentation and ossification; most are incidental. This article focuses on those anomalies of the thoracic vertebral bodies that lead to clinical signs of neurologic dysfunction. Based on a limited number of reported cases, the prognosis for surgically managed dogs with thoracic vertebral body abnormalities is favorable. PMID:26704660

    Congenital vertebral malformations (CVM) occur in 1 in 1000 live births and in many cases can cause spinal deformities, such as scoliosis, and result in disability and distress of affected individuals. Many severe forms of the disease, such as spondylocostal dystostosis, are recessive monogenic traits affecting somitogenesis, however the etiologies of the majority of CVM cases remain undetermined. Here we demonstrate that morphological defects of the notochord in zebrafish can generate congenital-type spine defects. We characterize three recessive zebrafish leviathan/col8a1a mutant alleles ((m531, vu41, vu105)) that disrupt collagen type VIII alpha1a (col8a1a), and cause folding of the embryonic notochord and consequently adult vertebral column malformations. Furthermore, we provide evidence that a transient loss of col8a1a function or inhibition of Lysyl oxidases with drugs during embryogenesis was sufficient to generate vertebral fusions and scoliosis in the adult spine. Using periodic imaging of individual zebrafish, we correlate focal notochord defects of the embryo with vertebral malformations (VM) in the adult. Finally, we show that bends and kinks in the notochord can lead to aberrant apposition of osteoblasts normally confined to well-segmented areas of the developing vertebral bodies. Our results afford a novel mechanism for the formation of VM, independent of defects of somitogenesis, resulting from aberrant bone deposition at regions of misshapen notochord tissue. PMID:24333517

    Congenital vertebral malformations are common in brachycephalic "screw-tailed" dog breeds such as French bulldogs, English bulldogs, Boston terriers, and pugs. The aim of this retrospective study was to determine whether a radiographic classification scheme developed for use in humans would be feasible for use in these dog breeds. Inclusion criteria were hospital admission between September 2009 and April 2013, neurologic examination findings available, diagnostic quality lateral and ventro-dorsal digital radiographs of the thoracic vertebral column, and at least one congenital vertebral malformation. Radiographs were retrieved and interpreted by two observers who were unaware of neurologic status. Vertebral malformations were classified based on a classification scheme modified from a previous human study and a consensus of both observers. Twenty-eight dogs met inclusion criteria (12 with neurologic deficits, 16 with no neurologic deficits). Congenital vertebral malformations affected 85/362 (23.5%) of thoracic vertebrae. Vertebral body formation defects were the most common (butterfly vertebrae 6.6%, ventral wedge-shaped vertebrae 5.5%, dorsal hemivertebrae 0.8%, and dorso-lateral hemivertebrae 0.5%). No lateral hemivertebrae or lateral wedge-shaped vertebrae were identified. The T7 vertebra was the most commonly affected (11/28 dogs), followed by T8 (8/28 dogs) and T12 (8/28 dogs). The number and type of vertebral malformations differed between groups (P = 0.01). Based on MRI, dorsal, and dorso-lateral hemivertebrae were the cause of spinal cord compression in 5/12 (41.6%) of dogs with neurologic deficits. Findings indicated that a modified human radiographic classification system of vertebral malformations is feasible for use in future studies of brachycephalic "screw-tailed" dogs. PMID:24833506

    International Nuclear Information System (INIS)

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.)

    Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

  14. Congenital cystic lung malformations

    International Nuclear Information System (INIS)

    Purpose: The aim of the study concerning congenital cystic lung malformations was to evaluate prenatal diagnoses postnatally to determine prognostic factors as well as to define optimized perinatal management. Materials and Methods: The study is based on 45 prenatal ultrasound examinations depicting fetal cystic lung lesions. 32 of the mothers had follow-up examinations. 5 pregnancies were terminated due to CCAM and additional malformations. Complete regression of the lesions was seen prenatally in 8 cases and postnatally in 5 children. Results: Surgical intervention due to respiratory insufficiency was necessary in 4 neonates. According to the imaging results, CCAM was present in 4 cases and sequestration in 7 patients. No correlation between the imaging findings and the surgical results was found in 3 children: One child suffered from rhadomyoid dysplasia, and in the case of the second child, a left-sided hernia of the diaphragm and additional sequestration were detected. The third child showed AV malformation. The cystic lesions of the 14 children operated upon were proven histologically. The degree of accuracy in the present study was high. Conclusion: Precise perinatal management is warranted in order to determine according to the clinical relevance surgical intervention and to prevent complications after the first year of life. This is performed during the neonatal period for respiratory insufficient neonates and within the first year of life for clinically stable children. (orig.)

    The prevalence of müllerian malformations is 1 in 200, or 0.5%. A third of the anomalies are septate, a third bicornuate uteri, 10% arcuate uterus, 10% didelphis and unicornuate uterus, and pregnancy rates. In contrast, surgical repair of a bicornuate uterus requires an abdominal metroplasty. This should only be performed if the patient has recurrent fetal loss due to the uterine structural defect. In a unicornuate uterus it is most important to determine if there is a second uterine horn that can cause cyclic pain if it has functioning endometrium. The only surgical option in these cases is to remove the rudimentary uterus with endometrium and hematometra, respectively. PMID:21437824

    International Nuclear Information System (INIS)

    Spondylocarpotarsal synostosis syndrome (SSS) is a rare autosomal recessive condition characterized primarily by vertebral malsegmentation, carpal/tarsal coalition, and a dysmorphic appearance. Differentiating SSS from other congenital scoliosis syndromes requires evaluation of the vertebrae, ribs, soft tissues, and spinal cord. The enhanced resolution over plain radiographs seen with MRI allows more detailed assessment of vertebral malformation and surrounding anatomy. Diagnosis of the underlying cause of congenital scoliosis might be enhanced using this technology. We report on a 12-year-old girl of unaffected parents with SSS who was evaluated with MRI sequences of the spine to show various types of malsegmentation. Additionally, there is the new finding of fusion of teeth, with developmental failure of a canine incisor. (orig.)

    1990-07-01

    We reviewed 40 cases of congenital malformations of the lung that were studied with both plain radiography and computed tomography (CT). We compared the CT findings with those of radiography. We found that CT was helpful in the management of these cases because it helped confirm the diagnosis, demonstrated unsuspected findings, and better depicted anatomic extent of anomalies, thus allowing better planning for surgery. We believe that CT is the method of choice for the study of congenital lung malformations and that it should be used before more invasive procedures such as bronchography or aortography.

MR findings of 11 cases with surgically proved anorectal malformations were retrospectively reviewed and compared with operative findings, according to the level of atresia, the development of sphincter muscle, fistula and associated anomalies of other organs. Four of 11 cases were low type of anorectal atresia, 3 cases were intermediate type, and 3 cases were high type. There was one case of Currarino triad with low type of anorectal stenosis. MRI demonstrated the levels of atresia correctly in all cases and revealed fistulas in all high type of anomalies. Degrees of the development of the sphincter muscles were good in all cases of low types and fair in a case of intermediate type and an anorectal stenosis, whereas the development was poor in 2 cases of intermediate type and all 4 cases of high type. The associated anomalies in anorectal malformation were renal agenesis, congenital hip dysplasia and sacral defect with presacral teratoma in Currarino triad.

    Congenital spinal malformations form a complex and heterogeneous group of disorders whose pathogenesis is best explained embryologically. Radiologically, it is important to formulate a diagnosis when the disorder first becomes symptomatic. However, it is also crucial to detect complications of the disorder or of the respective therapeutic interventions in the further course of the disease such as hydromyelia or re-tethering after repair of a meningomyelocele. Moreover, once a congenital spinal malformation is diagnosed, associated malformations should be sought after. A possible syndromal classification such as in OEIS- or VACTERL-syndromes should also be considered. (orig.) [German] Kongenitale spinale Malformationen stellen eine komplexe Gruppe an Stoerungen dar, deren Genese sich am einfachsten aus der Embryologie heraus erklaeren laesst. Bei der klinisch-radiologischen Begutachtung ist zunaechst ihre korrekte Klassifikation im Rahmen der Erstdiagnose wichtig. Im weiteren Verlauf ist es jedoch zudem entscheidend, moegliche Komplikationen wie beispielsweise eine Hydromyelie oder ein Wiederanheften des Myelons nach Operation einer Spina bifida aperta zu erkennen. Zudem sollte bei der Diagnosestellung einer kongenitalen spinalen Malformation immer auch auf assoziierte Fehlbildungen, wie z.B. die Diastematomyelie oder das intraspinale Lipom bei der Spina bifida aperta, sowie auf eine moegliche syndromale Einordnung wie beispielsweise beim OEIS-oder VACTERL-Syndrom geachtet werden.

  2. Congenital vascular malformations in scintigraphic evaluation

    International Nuclear Information System (INIS)

    Congenital vascular malformations are tumour-like, non-neoplastic lesions caused by disorders of vascular tissue morphogenesis. They are characterised by a normal cell replacement cycle throughout all growth phases and do not undergo spontaneous involution. Here we present a scintigraphic image of familial congenital vascular malformations in two sisters. A 17-years-old young woman with a history of multiple hospitalisations for foci of vascular anomalies appearing progressively in the upper and lower right limbs, chest wall and spleen. A Parkes Weber syndrome was diagnosed based on the clinical picture. Due to the occurrence of new foci of malformations, a whole-body scintigraphic examination was performed. A 12-years-old girl reported a lump in the right lower limb present for approximately 2 years, which was clinically identified as a vascular lesion in the area of calcaneus and talus. Phleboscintigraphy visualized normal radiomarker outflow from the feet via the deep venous system, also observed in the superficial venous system once the tourniquets were released. In static and whole-body examinations vascular malformations were visualised in the area of the medial cuneiform, navicular and talus bones of the left foot, as well as in the projection of right calcaneus and above the right talocrural joint. People with undiagnosed disorders related to the presence of vascular malformations should undergo periodic follow-up to identify lesions that may be the cause of potentially serious complications and to assess the results of treatment. Presented scintigraphic methods may be used for both diagnosing and monitoring of disease progression

    Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.

    Full Text Available Congenital malformations, congenital anomalies and innate defects (present at birth are synonymous terms used to describe structural, functional or metabolic disorders present at birth. The science that studies the causes of these disorders is called teratology (Greek teratos = monster. As genetic and malformative disorders are very diverse, appear at different ages and affect any system or organ, the patients who suffer of these diseases can be examined by a specialist doctor, all the medical practitioners facing genetic pathology should know some principles of genetic medicine. They also should know and apply the general methodology of genetic examination, should be able to indicate the necessary genetic explorations, as well as to correctly understand and interpret their results and should be able to advice genetically in a correct manner - within his/her area of competence – the patient and/or the family facing a genetic risk. Major structural anomalies appear in 2-3% in live newborns and other 2-3% are discovered in children up to 5 years old, summarizing 4-6%. Birth defects are the first causes of infantile mortality, accounting for approximately 25% of all neonatal deaths. Minor anomalies appear in approximately 15% out of the total of newborns. These anomalies do not alter the individual’s health status, but they are associated with major defects in some cases, therefore they can serve as key elements for the diagnosis of more serious, hidden defects.

    2008-01-01

    Full Text Available Aim: Pediatric lung resection is a relatively uncommon procedure that is usually performed for congenital lesions. In recent years, thoracoscopic resection has become increasingly popular, particularly for small peripheral lesions. The aim of this study was to review our experience with traditional open lung resection in order to evaluate the existing "gold standard." Materials and Methods: We carried out a retrospective analysis of all children having lung resection for congenital lesions at our institution between 1997 and 2004. Data were collected from analysis of case notes, operative records and clinical consultation. The mean follow-up was 37.95 months. The data were analyzed using SPSS. Results: Forty-one children (13 F/28 M underwent major lung resections during the study period. Their median age was 4.66 months (1 day-9 years. The resected lesions included 21 congenital cystic adenomatoid malformations, 14 congenital lobar emphysema, four sequestrations and one bronchogenic cyst. Fifty percent of the lesions were diagnosed antenatally. Twenty-six patients had a complete lobectomy while 15 patients had parenchymal sparing resection of the lesion alone. Mean postoperative stay was 5.7 days. There have been no complications in any of the patients. All patients are currently alive, asymptomatic and well. None of the patients have any significant chest deformity. Conclusions: We conclude that open lung resection enables parenchymal sparing surgery, is versatile, has few complications and produces very good long-term results. It remains the "gold standard" against which minimally invasive techniques may be judged.

    2009-12-01

    Full Text Available Introduction: Congenital anomalies represent a significant cause of premature birth, of child morbidity and mortality. From 200000 new born per year, over 10000 presented malformations. Epidemiologic studies have shown that the incidence of malformations is increasing and varies upon geographic features, race and gender. Perinatal mortality is generated in 66.66% of cases by congenital malformations, illnesses from perinatal period and the rest of them is generated by the birth. Material and Method: The study was retrospective and was carried on for a period of five years (2003-2007 based on medical records and on laboratory results, (especially those for TORCH screening: toxoplasmosis, rubella, cytomegalovirus, and herpes virus. Results: Major structural anomalies were present at 39.51% (388 cases of 982 patients which were registered in Genetic Pathology Center from Pediatric Clinics I, Cluj-Napoca. Diagnosed abnormalities included: congenital malformations of circulatory, respiratory, digestive, central nervous system, congenital malformations of skeletal system, Down syndrome, which is consistent with results of other studies showing that the most common are heart abnormalities (33.06%, followed in descending order of frequency by urinary, genital, CNS, skin, oral-facial cleft and digestive anomalies. Conclusions: Early detection of major malformation during early pregnancy can indicate for medical termination of pregnancy to reduce the high morbidity and mortality of neonates due to congenital malformations. So proper and timely counselling, regular antenatal care with folate supplementation especially during the most sensitive period of embryogenesis is essential to avoid major congenital malformation for future pregnancy.

  12. Amplatzer vascular plugs in congenital cardiovascular malformations

    International Nuclear Information System (INIS)

    Amplatzer vascular plugs (AVPs) are devices ideally suited to close medium-to-large vascular communications. There is limited published literature regarding the utility of AVPs in congenital cardiovascular malformations (CCVMs). To describe the use of AVPs in different CCVMs and to evaluate their safety and efficacy. All patients who required an AVP for the closure of CCVM were included in this retrospective review of our catheterization laboratory data. The efficacy and safety of AVPs are reported. A total of 39 AVPs were implanted in 31 patients. Thirteen (33%) were AVP type I and 23 (59%) were AVP type II. AVP type III were implanted in two patients and type IV in one patient. The major indications for their use included closure of pulmonary arteriovenous malformation (AVM) (n = 7), aortopulmonary collaterals (n = 7), closure of a patent Blalock-Taussig shunt (n = 5), systemic AVM (n = 5), coronary AVM (n = 4), patent ductus arteriosus (PDA) (n = 3), pulmonary artery aneurysms (n = 3), and venovenous collaterals (n = 2). Deployment of the AVP was done predominantly via the 5 – 7F Judkin's right coronary guide catheter. Overall 92% of the AVPs could be successfully deployed and resulted in occlusion of the target vessel in all cases, within 10 minutes. No procedure-related or access site complication occurred. AVPs are versatile, easy to use, and effective devices to occlude the vascular communications in a variety of settings. AVP II is especially useful in the closure of tubular structures with a high flow

    The frequency and outcome of twin pregnancies in women with uterine malformation were studied. The cohort comprised 13 (4.9%) women with twin pregnancy found among 263 women. They had 483 deliveries, 13 of them twins (2.7%; 95% CI 1.6-4.6%). Among 38 patients with unicornuate uterus 5 (6.8%) out of 74 deliveries were twins, 39 women with didelphic uterus 2 (3.2%) out of 62 deliveries and 147 women with septate or subseptate uterus 6 (2.3%) out of 264 deliveries were twins. The mean duration of gestation was 249 days (range 190-268 days), 5 (38%) out of 13 deliveries were premature, 25 out of 26 newborns were alive. Mean durations of gestation and mean weights of newborns did not differ when 7 cases with unicornuate or didelphic uterus were compared to 6 cases with complete or partial uterine septum. A congenital malformed uterus can bear twin pregnancy without severe complications apart from prematurity. PMID:26757792

  14. Transcatheter arterial embolization for congenital renal arteriovenous malformation

    International Nuclear Information System (INIS)

    Objective: To evaluate the effectiveness of transcatheter arterial embolization for congenital renal arteriovenous malformation. Methods: Seven cases of congenital renal arteriovenous malformation causing gross hematuria were retrospectively studied. All of 7 cases were demonstrated by means of angiography and then the catheter was placed superselectively into the involved arterial end of the malformation undertaking embolization with gelfoam, dehydrated ethanol, coils, etc. Results: All the malformations of the 7 cases were successfully embolized with stoppage of gross hematuria within 24 hours. No serious complications occurred except lumbago, fever, gastrointestinal reaction for one week. There was no recurrence of haematuria and the renal function was also normal in all cases during the follow-up for 36 to 98 months. Conclusions: Transcatheter renal arterial angiography and embolization are the important and effective management for the diagnosis and treatment of congenital renal arteriovenous malformation.

    In order to determine the value of MRI in diagnosing congenital cardiovascular malformations, MR Images were obtained in 25 adult patients with congenital cardiovascular malformations. Gated MRI detected all of 13 atrial septal defects, and all of 4 ventricular septal defects, but ungated MRI detected none of 3 atrial septal defects. Other congenital cardiovascular malformations (2 with Ebstein's disease, 1 with Fallot's pentalogy, and 1 with Pulmonary stenosis) were well visualized. Vascular malformations (1 with Patent ducts arteriosus, 1 with Supravalvelar aortic stenosis, 1 with Coarctation of Aorta, 1 with Right Aortic Arch) were well visualized in all of 7 patients by ungated MRI. MRI was a valuable noninvasive method of diagnosing congenital heart disease. (author)

  9. Congenital Malformations in Neonates after irradiation of Rats During Pregnancy

    International Nuclear Information System (INIS)

    Radiation is considered a teratogen during the whole period of embryonic development and fetal growth. However, the time of gestation at which irradiation takes place will affect the type of congenital malformation Induced. A study was carried out to observe various forms of congenital malformations induced after irradiation of pregnant rats to 1,2 and 3 Gy on the 9th , 12th and 15th days of gestation. Various types of congenital malformations were observed in the neonates of irradiated animals as compared to controls. Most of the malformations were observed in neonates of animals irradiated with 2 and 3 Gy on the 12th and 15th days of gestation. This confirms that developmental anomalies occur mostly during the period of organ development. Other periods of gestation are less vulnerable to, induction of malformation after irradiation. Some representative photographs of the malformations induced such as penguin shape, absence of tail, low set ears, growth retardation and others are illustrated in the text

  10. Diffusion imaging and tractography of congenital brain malformations

    International Nuclear Information System (INIS)

    Diffusion imaging is an MRI modality that measures the microscopic molecular motion of water in order to investigate white matter microstructure. The modality has been used extensively in recent years to investigate the neuroanatomical basis of congenital brain malformations. We review the basic principles of diffusion imaging and of specific techniques, including diffusion tensor imaging (DTI) and high angular resolution diffusion imaging (HARDI). We show how DTI and HARDI, and their application to fiber tractography, has elucidated the aberrant connectivity underlying a number of congenital brain malformations. Finally, we discuss potential uses for diffusion imaging of developmental disorders in the clinical and research realms. (orig.)

    International Nuclear Information System (INIS)

    Objective: To discuss the effect and safety of trans-microcatheter arterial embolization with ethanol for the treatment of congenital renal arteriovenous malformations. Methods: Clinical data of 11 patients with congenital renal arteriovenous malformations manifested mainly as gross hematuria were retrospectively analyzed. Selective renal angiography was performed in all 11 patients. After the diagnosis was confirmed, super-selective catheterization of the diseased arteries was carried out and the trans-microcatheter arterial embolization with ethanol was conducted. Results: A total of 12 procedures were completed in 11 patients. The ethanol dose used in one procedure was 5-25 ml. Successful embolization of the congenital renal arteriovenous malformations was obtained in all patients. The gross hematuria disappeared within 24-48 hours after the treatment. Lumbago at treated side, low fever, abdominal distension, nausea, vomiting, etc. occurred within one week and no other serious complications developed. During the follow-up period lasting for 4-96 months, no recurrence of hematuria was observed and the renal function remained normal. Conclusion: Transcatheter arterial ethanol embolization is an economic, safe and effective treatment for congenital renal arteriovenous malformations. (authors)

    Full Text Available Dandy Walker Malformation (DWM is a congenital malformation involving the cerebellum and fluid filled spaces around it. A key feature of this syndrome is partial or complete absence of a part of brain located between two cerebellar hemispheres ie. cerebellar vermis.(1 Dandy walker malformation was originally described in 1887 by Sutton and further characterized by Dandy and Blackfan in 1914 followed by Tagart and Walker in 1942. Benda finally labeled this disease as Dandy Walker in 1954. (2 Since the original description, additional studies have reported on various morphological features of this syndrome. It is a genetically sporadic disorder that occurs one in every 30,000live births. (3 Because of its rarity, here we report a case of DWM, in a fetus in which the diagnosis was made prenatally on USG. Later on, MTP was done by expulsion. Fetus was sent for autopsy to rule out other associated congenital abnormalities

  5. Pattern of congenital brain malformations at a referral hospital in Saudi Arabia: An MRI study

    International Nuclear Information System (INIS)

    More than 2000 different congenital cerebral malformations have been described in the literature, for which several classification systems have been proposed. With the help of these classification systems, it is now possible, with neuroimaging, to time neuroembtyologic events. Magnetic resonance imaging (MRI), in particular, is useful in studying these malformations. This study evaluated the pattern of congenital brain malformations in a university referral hospital setting. The records of all MRI brain examinations at our hospital over a period of 3 years for children younger than 15 years of age were reviewed. Cases of congenital cerebral malformations were analyzed by sex, age at presentation, type of congenital cerebral malformation and other associated congenital cerebral malformations. Of the 808 MR examinations of different parts of the body for children in the study period, 719 (89%), on 581 patients, were of the brain. Eighty-six children (14.8%) were found to have single or multiple congenital brain malformations. In these children, 114 congenital brain malformations were identified, the commonest being cortical migrational defects (25 patients, 22%), neural tube closure defects (22 patients, 19%), and corpus callosum dysgenesis (22 patients 19%). The least common was vascular malformation. Sixteen patients (18.6%) had more than one congenital brain malformations. Neural tube closer defects, cortical migrational abnormalities, and corpus callosum anomalies were the commonest congenital brain malformations, while vascular malformations were the least common. Most of the identified malformations demonstrated the usual pattern, but a few showed unusual patterns and associations. (author)

    A male black and white German Holstein calf showed a congenital, high-graded scoliosis and rotation of the thoracal spinal cord associated with shortening and fusion of multiple vertebral bodies and abnormal bending of the processus spinosus. Furthermore reduced birth weight, partial hypoplasia of the lung, excessive liver segmentation, doubled gall bladder, rectal atresia, horseshoe kidney, and uterine atresia were found. Due to the exclusion of a point mutation in exon 4 of the solute carrier family 35 (UDP-N-acetylglucosamine (UDP-GlcNAc) transporter), member A3 (SLC35A3) gene, complex vertebral malformation (CVM) was ruled out. Conclusively, it is hypothetized that the presented case resembles a new brachyspina syndrome with a still unresolved genetic etiology. PMID:20496833

    Full Text Available Airways with lung parenchyma and foregut develop from primitive foregut. Bronchopulmonary foregut molformations are the name of congenital, structural, often sporadic and non-hereditary anomalies including vessel anomalies formes during individual development of these two system following their separation from each other. The wideley observed forms are summarise in the context of this article. Congenital diaphragmatic hernia (CDH is a disease that is coused by the incomplete maturation of the diaphragm and a defect mostly on the left side, at the postero-lateral portion of the diaphragm. Diaphragm completes its growth around 4th-8th gestational age. If not then the abdominal viscera moves into the thoracic cavity and lung development is insufficient due to compression of the abdominal organs.This also causes maturation problem at the pulmonary arteries and ends up with severe pulmonary hipertansion that might be highly fatal in the newborns.

  9. Congenital malformations and infant mortality from the Chernobyl reactor accident

    International Nuclear Information System (INIS)

    The health impact of radiological contamination in Bavaria from the Chernobyl accident was evaluated. According to caesium 137 levels in soil samples, Bavaria was subdivided in a higher contaminated region (Southern Bavaria) and a lower contaminated region (Northern Bavaria). Indicators for health effects were congenital malformations, perinatal mortality, and infant mortality. Definition of the study periods accounted for the temporal relationship between conception as well as organogenesis and the time of highest exposure to radioactivity during the first weeks of May 1986. Statistical analysis was based on a combined spatial and temporal comparison. The results of the study do not show a significant increase in any of the outcome variables. Consequently, this study provides no evidence that radiation from Chernobyl caused a rise in the birth prevalence of congenital malformations or perinatal and infant mortality in the Bavarian population.

    Full Text Available Abstract Background A detailed behavioral profile associated with focal congenital malformation of the ventromedial prefrontal cortex (vmPFC has not been reported previously. Here we describe a 14 year-old boy, B.W., with neurological and psychiatric sequelae stemming from focal cortical malformation of the left vmPFC. Case Presentation B.W.'s behavior has been characterized through extensive review Patience of clinical and personal records along with behavioral and neuropsychological testing. A central feature of the behavioral profile is severe antisocial behavior. He is aggressive, manipulative, and callous; features consistent with psychopathy. Other problems include: egocentricity, impulsivity, hyperactivity, lack of empathy, lack of respect for authority, impaired moral judgment, an inability to plan ahead, and poor frustration tolerance. Conclusions The vmPFC has a profound contribution to the development of human prosocial behavior. B.W. demonstrates how a congenital lesion to this cortical region severely disrupts this process.

    We studied clinical and EEG features of 36 cases with congenital malformations of the CNS. Patients were followed at the outpatient clinic of Hospital Cayetano Heredia and of Hogar Clinica San Juan de Dios in Lima-Peru, from January 1984 to June 1992. Eighty percent of the patients had convulsive syndromes and mental retardation. The most frequent malformation was agenesis of corpus callosum, and it was not possible to find a "typical" EEG pattern. The second were porencephalic cysts, with a good clinical-EEG correlation. There were two typical cases of schizencephaly, one of hemimegalencephaly with good prognosis, and one of holoprosencephaly. The results are compared to those obtained for a series we previously reported. Data discussed take into account reports on the subject registered in the literature. It is concluded that EEG is an useful method to evaluate possible CNS malformations in developing countries. PMID:7611945

  18. Magnetic resonance venography of congenital vascular malformations of the extremities

    International Nuclear Information System (INIS)

    Contrast angiography can demonstrate the vascular components of a vascular malformation, but can be technically challenging in small patients with complex venous anomalies. We reviewed the role of magnetic resonance venography (MRV) in the evaluation of children with predominantly low-flow, vascular malformations of the extremities. MRV (2D time-of-flight technique) and magnetic resonance (MR) imaging examinations were performed in ten young patients with congential predominantly low-flow vascular malformations of the extremities. MR imaging was used to characterize and determine the extent of the malformations, and MRV to evaluate the deep and superficial venous channels. In all patients, MRV studies were reviewed in conjunction with contrast angiograms, considered the gold standard, to confirm the findings. All signficant channel anomalies seen with contrast angiography were identified with MRV. In addition, MRV demonstrated some veins that were not intentionally opacified during contrast studies. MRV demonstrates both the superficial and deep conducting veins, whereas contrast angiography is a more directed study, evaluating only those channels intentionally opacified. Together, MR imaging and MRV data can non-invasively form the basis for determining the prognosis and choosing the individual treatment of congenital vascular malformations of the extremities.

  19. Transgenerational transmission of radiation damage. Genomic instability and congenital malformation

    International Nuclear Information System (INIS)

    The congenital malformation gastroschisis has a genetic disposition in the inbred mouse strain HLG/Zte. It is increased after preconceptional irradiation of males or females. Radiation exposures during the meiotic stages are most efficient. This malformation can also be induced by ionising radiation when the exposure takes place during the preimplantation period especially during the zygote stage. This latter effect can be transmitted to the next mouse generation. Other macroscopically visible or skeletal malformations are not significantly induced under these experimental conditions. These latter malformations are increased by radiation exposures during major organogenesis. The mechanisms for the development of the effects are different. Radiation exposure of the mouse zygote (1 to 3 hours p.c.) also leads to the induction of genomic instability in skin fibroblasts of the fetus. This phenomenon also occurs in a mouse strain (C57BL/6J) which is not susceptible to radiation-induced gastroschisis during the preimplantation period. The genomic instability is transmitted to the next mouse generation. During genomic instability chromatide breaks are dominating as in non-exposed cells. With respect to ''spontaneous'' malformations gastroschisis is dominating in HLG/Zte mice. Late radiation effects seem to have similar patterns as observed in non-exposed subjects, however, the rates are increased after irradiation. (author)

    International Nuclear Information System (INIS)

    Background. Intralobar sequestration (ILS) has been suggested to be an acquired lesion. However, we have observed several young infants who had ILS. Objectives. Since this fact seems to indicate a congenital origin, we reviewed our experience. Material and methods. A retrospective review of bronchopulmonary sequestration from the Departments of Radiology and Pathology in Lund between 1964 and 1997. Results. We identified seven infants or young children with a diagnosis of intralobar sequestration. In each patient, the ILS was present before recurrent infection developed. Five had chest X-rays as neonates, one at 3 months and one at 11 months of age. All but one showed an abnormality on their first chest X-ray, consistent with sequestration. Six of the ILS were verified at angiography; all seven were surgically removed. Two of the children with ILS also had congenital cystic adenomatoid malformation (CCAM). Three children had both ILS and scimitar syndrome. Conclusions. The fact that ILS was present in seven newborn and young infants indicates that this lesion is, at least in some patients, a congenital malformation. (orig.)

    Congenital nephrotic syndrome (CNS) is a rare disease inherited as an autosomally recessive trait and defined as proteinuria manifesting at birth or in the first 3 months of life. The classical form is the Finnish type of CNS (CNF), which is caused by mutations in the nephrin gene (NPHS1). The classical findings include prematurity, large placenta and massive proteinuria. Minor cardiac findings have been reported as a minor functional disorder but CNS with major cardiac malformation is rare. Here we report the case of a Turkish child with CNS with small indel mutation (c.614_621delCACCCCGGinsTT) in exon 6 of NPHS1 and also major cardiac malformation who did not develop end-stage renal disease until the age of 5 years.

    Full Text Available Introduction: Congenital malformations of the urinary system are risk factors for the development of urinary tract infections (UTI. Besides the severity of the malformation, urinary infection is always associated with poor prognosis for these patients. Late discovery of the malformation background, after several urinary tract infection episodes, contributes to the development of chronic pyelonephritis that may lead to chronic renal failure.

    Vertebral column pathologies requiring surgical intervention have been described in pet ferrets, however little information is available on the normal vertebral formula and congenital variants in this species. The purpose of this retrospective study was to describe vertebral formulas and prevalence of congenital vertebral anomalies in a sample of pet ferrets. Radiographs of 172 pet ferrets (96 males and 76 females) were included in this retrospective study. In 143 ferrets (83.14%), five different formulas of the vertebral column were recorded with normal morphology of vertebrae (rib attachment included) but with a variable number of thoracic (Th), lumbar (L), and sacral (S) vertebrae. The number of cervical (C) vertebrae was constant in all examined animals. Observed vertebral formulas were C7/Th14/L6/S3 (51.74%), C7/Th14/L6/S4 (22.10%), C7/Th14/L7/S3 (6.98%), C7/Th15/L6/S3 (1.74%), and C7/Th15/L6/S4 (0.58%). Formula C7/Th14/L6/S4 was significantly more common in males than in females (P vertebrae represented the most common congenital abnormalities (26 ferrets) in the thoracolumbar (13 ferrets) and lumbosacral regions (10 ferrets) or simultaneously in both regions (three ferrets). Other vertebral anomalies included block (two ferrets) and wedge vertebra (one ferret). Spina bifida was not detected. Findings from the current study indicated that vertebral formulas may vary in ferrets and congenital abnormalities are common. This should be taken into consideration for surgical planning.

  2. Monitoring of congenital malformations in Belarus after the Chernobyl accident

    International Nuclear Information System (INIS)

    An investigation of over 21,000 embryos and fetuses from medically-induced abortions was conducted from 1980 through 1991 in the Republic of Belarus. More than half of the abortions studied were carried out after the Chernobyl nuclear accident, including 1176 from districts with 137Cs soil contamination levels over 0.6 TBq/km2 (15 Ci/km2). Congenital malformations (CM's) in 7325 newborn children also were analyzed. The data on these children were obtained from a genetic monitoring program. It was shown that in the 5 years after the Chernobyl accident the frequency of abnormal developments in aborted fetuses from contaminated areas was significantly higher than in aborted fetuses from Minsk, which was relatively uncontaminated. Additionally, the CM incidence in newborn children increased in Belarus compared to the CM incidences before the accident; the increase was most significant in the heavily contaminated areas. The increases were attributed primarily to CMS characterized by dominant mutations. These increases could have been partially caused by factors unrelated to radiation dose, including defective nourishment, chemical contaminants, and psychological stresses. A correlation between CM increase and the parents' dose has not been established. 17 refs., 6 tabs

    Monitoring and surveillance strategies are imperative for managing genetic defects in livestock populations in order to avoid detrimental effects on animal welfare and productivity. Recently, a number of previously unknown defects have been described in cattle, fostered by the huge progress in genome analysis and genomic selection. In response to reports about a potentially new defect in Holstein cattle, case-control studies were carried out to confirm a genetic background of the defect and to evaluate its phenotypic relevance. Eighty-five potentially affected offspring of a suspected carrier sire for the defect and 41 matched control calves were subjected to clinical and epidemiological monitoring on 39 farms. Forty-one animals, all offspring of the suspected carrier sire, showed pathognomonic tail malformations providing highly significant evidence for a congenital inherited defect, which was subsequently termed vertebral and spinal dysplasia (VSD). The defect is characterised by vertebral (specifically tail) deformities and neurological dysfunctions with gait abnormalities of the hind limbs. The deformities and neurological dysfunctions varied from very mild (only tail deformities) to severe (paraparesis). Detailed epidemiological monitoring provided no indication of environmental factors affecting VSD. The malformations and dysfunctions associated with VSD, as well as its mode of inheritance and the genotyping of the suspected carrier sire, indicated that VSD is a defect previously not described in cattle. VSD is inherited in a dominant mode, but shows incomplete penetrance of the phenotype, which impedes unequivocal identification of VSD carriers. A direct diagnostic genetic test for VSD is available.

    A descriptive study in 351 patients at the Nephrology and Urology Services at 'Octavio de la Concepcion de la Pedraja' Teaching Pediatric Hospital from January 1999 to December 2005, was carried out. 535 kidney and urinary tract congenital malformations of 19 types were diagnosed. Primary vesicoureteral reflux and ureteropyelic stenosis were the most frequently malformations. The majority of these patients were diagnosed during the first year of the life. The most frequently clinic manifestation was urinary tract infection. Ultrasound study and cystouretrography were effective to diagnose these malformations. The majority of patients with prenatal diagnosis had congenital hydronephrosis. Posterior urethral valves were the principal cause of chronic renal failure. The I, II and III grades of Primary Vesicoureteral Reflux disappeared spontaneously with conservative treatment. There was a direct relationship between Reflux Nephropathy and the grade of these malformations

    Full Text Available We investigated the chromosomal constitution of patients with mental retardation and/or congenital malformations in order to determine genetic causes for such disturbances. The GTG and CBG banding patterns were studied using phytohemagglutinin M-stimulated lymphocytes cultured from peripheral blood. Among 98 individuals with mental retardation and/or congenital malformations who were analyzed there were 12 cases of Down's syndrome, two of Edward's syndrome, one of Patau's syndrome, five of Turner's syndrome, two of Klinefelter's syndrome, one of "cri-du-chat" syndrome, one case of a balanced translocation between chromosomes 13 and 14, one case of a derivative chromosome and one of a marker chromosome. We found abnormal chromosomes in 26% of the patients, 82% of which were numerical abnormalities, with the remaining 18% being structural variants. We conclude that patients with mental retardation and/or congenital malformations should be routinely karyotyped.

  12. Congenital malformation and fetal mortality trends in counties surrounding Oak Ridge

    International Nuclear Information System (INIS)

    Stillbirth and congenital malformation death data have been evaluated for counties surrounding the Oak Ridge nuclear facilities. The observed values were compared with expected values, based on state of Tennessee and East Tennessee rates, for three time periods: prior to the existence of the nuclear facilities; the early years of operation; and the later years of operation. Oak Ridge, which is the closest city to the nuclear facilities, had significantly fewer stillbirths and no difference in congenital malformations as compared with the state or East Tennessee. No time trend was observed in the 8-county data which could be associated with the higher levels of radioactive releases during the 1944 to 1957 period followed by a period of lesser releases in the 1958 to 1971 period. However, a clustering of stillbirths was found for the last time period. In the study, no significant relationship was found between the occurrence of stillbirths and congenital malformation deaths

  13. Surveillance of congenital malformations in Belarus. Chernobyl aftermath

    International Nuclear Information System (INIS)

    Full text: In order to study possible genetic effects of the Chernobyl accident in human population a comparative analysis of the prevalence at birth of congenital malformations (CM) was performed on region and area administrative levels basing on the data of Belarus registry of CM permanently functioning since 1979. An attempt was made to evaluate dose dependence of the effects under study. We analyzed time trends of the prevalence at birth of 9 so called 'mandatory registered' nosologic units of CM. These group of CM could be easily diagnosed within the neonatal period and were assigned for registration at creation of the registry. Over 12 thousand cases registered within the period of 1981 to 2004 in 4 regions as well as about 3 thousand cases found in 47 rayons highly contrasting by radiation exposure were scrutinized. No long-term impact of the Chernobyl release on prevalence rates of surveyed CM was shown. Since the middle 80-s a similar steady increasing trend was observed as in contaminated, as in control areas with a tendency to stabilization after middle 90-s. We fail to reveal a dose dependence for CM prevalence rates calculated for the whole post-accidental period. Nonetheless, during the first years after the accident situation in contaminated areas was notably different from those in the control. Within the period of 1987 to 1989 a significant access of CM prevalence was registered in the strict radiological control area (Cs 137 soil contamination over 555 kBq/m2) as compared to non-contaminated zone. Relative risk was estimated as RR1987-1989 = 1.57 with 95% confidence interval being 95%CI = [1.29; 1.89]. Before the accident no difference in prevalence rates was marked (RR1981-1986 = 0.93; 95%CI = [0.80; 1.09]); nor it was evident in the farther post-accidental period (RR1990-2004 = 0.99; 95%CI = [0.80; 1.09]). Anomalies with high contribution of dominant de novo mutations (polydactyly, reduction defects of limbs and multiple CM) played principal role in the revealed increase. For this CM group a correlation with the estimated effective dose values was observed within the corresponding time period, no such relationship was marked for other analyzed CM, however. Analysis of the farther period failed to reveal a similar association for any group of CM under study. Thus, adverse effect of the Chernobyl accident on fetal development could not be excluded only within the first years after the accident. Peculiarity of the group of anomalies, chosen for the study, limits the impact of screening effect; however, it could not be completely ruled out because of ecological study design. Obtained results need to be confirmed in consecutive series of case-control and cohort studies. Extensive implementation of prophylactics of CM in the early 90-s made it possible to maintain the CM prevalence rates among newborns at the pre-accidental values. Currently over 30% of mandatory registered CM and about 20% of all CM in Belarus are registered among fetuses aborted for genetic reasons. Nevertheless, rather high level of CM prevalence in the republic insists farther improvement of the prophylactics of malformed children birth. For this purpose similar measures seems to be appropriate as for the residents of contaminated, as non-contaminated areas, since currently no substantial difference in time trends are traceable. The most perspective way of improvement of CM prenatal diagnostics is enlargement of the group of women that undergo ultrasound screening of I and II trimesters in specialized centers of prenatal diagnostics

Material and Methods: A descriptive, retrospective study of newborns presenting CCAM in a tertiary care hospital in Madrid, Spain. Results: Seven patients were found. All were full term, normal weight births. Two patients showed respiratory distress at birth. Two chest x-rays were normal. CT scans showed three clear CCAM lesions, four suggestive of hybrid lesions. All were referred to medical centers with pediatric surgery for followup. Discussion: At birth, this pathology may be asymptomatic and appear as a chest x-ray finding. Long term management is complicated by infection and malignization. Conservative treatment of asymptomatic patients includes regular follow up of lesions. Surgical treatment is reserved for symptomatic or complicated patients. Conclusions: Prenatal suspicion of CCAM is important since clinical exam and radiology may be normal in neonatal period. Chest CT scans are important in confirming diagnosis and determining future surgery. More studies are necessary for the proper diagnosis and management of this disorder.

    PurposeThis manuscript describes the clinical features, imaging findings, treatment details, and short-term outcomes of a series of congenital slow-flow vascular malformations.MethodsThis was a prospective study of congenital slow-flow vascular malformations involving the orbital region treated at a single institution with percutaneous sclerotherapy.ResultsTen patients presented during the study period, comprising eight venous malformations, one lymphatic malformation, and one veno-lymphatic malformation. Nine patients underwent percutaneous sclerotherapy under digital subtraction angiography guidance, of which three developed marked rise in intraocular pressure requiring lateral canthotomy. The treatments were performed in the presence of an ophthalmologist who measured the intraorbital pressure during and after the procedure. On follow-up, some of the patients required repeat sessions of sclerotherapy. All patients had improvement of symptoms on follow up after the procedure.ConclusionCongenital slow-flow vascular malformations of the orbital region are rare lesions that should be treated using a multidisciplinary approach. Monitoring of the intraorbital pressure is required both during and after the procedure to decide about the need for lateral canthotomy to reduce the transiently increased intraorbital pressure.

    The study concentrates on the genetic after-effects of the Chernobyl accident in some districts of Kaluga's region. The frequencies and range of congenital malformations, prematurely death-rate in the radionuclear polluted districts were compared with the control districts. Prematurely death-rate in compared regions is the same. The increase of the congenital malformation frequency is revealed in one the polluted districts (256/10000) as compared with the control one (27/10000). We assume that the observed effect is mainly connected with the professional activity of the population. 11 refs., 4 tabs

    Full Text Available Abstract Background The plastic monomer and plasticizer bisphenol A (BPA, used for manufacturing polycarbonate plastic and epoxy resins, is produced at over 2.5 million metric tons per year. Concerns have been raised that BPA acts as an endocrine disruptor on both developmental and reproductive processes and a large body of evidence suggests that BPA interferes with estrogen and thyroid hormone signaling. Here, we investigated BPA effects during embryonic development using the zebrafish and Xenopus models. Results We report that BPA exposure leads to severe malformations of the otic vesicle. In zebrafish and in Xenopus embryos, exposure to BPA during the first developmental day resulted in dose-dependent defects in otolith formation. Defects included aggregation, multiplication and occasionally failure to form otoliths. As no effects on otolith development were seen with exposure to micromolar concentrations of thyroid hormone, 17-ß-estradiol or of the estrogen receptor antagonist ICI 182,780 we conclude that the effects of BPA are independent of estrogen receptors or thyroid-hormone receptors. Na+/K+ ATPases are crucial for otolith formation in zebrafish. Pharmacological inhibition of the major Na+/K+ ATPase with ouabain can rescue the BPA-induced otolith phenotype. Conclusions The data suggest that the spectrum of BPA action is wider than previously expected and argue for a systematic survey of the developmental effects of this endocrine disruptor.

  11. Congenital malformations and damage in early infancy of the central nervous system

    International Nuclear Information System (INIS)

    Congenital malformations and cerebral damage in early infancy cause complex morphological and clinical changes. Modern imaging techniques, and especially NMR, have provided deeper knowledge of these diseases in the past few years. Based on the neuroradiological findings, the book presents a complete picture of congenital malformations of the central nervous systems and cerebral damage in early infancy; it describes the underlying pathomechanisms, clinical symptoms and therapies. Neurologists and neuropaediatricians are enabled to diagnose malformations correctly and to develop optimal therapy strategies in cooperation with other medical disciplines. Neuroradiologists and radiologists, on the other hand, will find a manual for correct interpretation and differential diagnosis of their findings and a guide for interpreting the findings and deciding further therapeutic or diagnostic interventions.

  12. Major congenital malformations in the high and normal level radiation areas of southwest coast of Kerala

    International Nuclear Information System (INIS)

    Congenital malformations are defects in organogenesis during the fetal periods and its influence on the individual may vary according to the type of malformation. Some congenital malformations are trivial and may not have any significance but for a minimal cosmetic deformity. Major malformations on the contrary may be severe enough to be life-threatening with serious structural, functional or cosmetic disability requiring surgical or medical management and are an important cause of mortality and morbidity all over the world. The present paper analyses the major malformations detected during the monitoring of newborns in selected government hospitals in and around the high level natural radiation areas of Kerala, a narrow strip of land in the southwest coast extending from Purakkad panchayat of Alapuzha district in the north to Neendakara Panchayat of Quilon district in the south. The coastal area has natural deposits of Monazite sand containing Thorium. Thorium together with its daughter products accounts for the elevated levels of natural radiation. The finding in general was in conformity with similar works on malformations

  14. Preoperative diagnosis and surgical strategy in congenital auditory ossicular malformation of 26 ears

    International Nuclear Information System (INIS)

    We retrospectively analyzed 26 ears of 21 subjects having auditory ossicular malformation and who had undergone auditory reconstruction between April 2004 and December 2010 at our clinic. We checked preoperative condition, pathological classification, surgical procedure, and hearing improvement. We could predict pathological conditions precisely from preoperative computed tomography (CT), including incudostapedial disconnection (9/12, 75%) and malleus and/or incus fixation (7/12, 58%), which tended to be present in external ear malformation, and stapes footplate fixation (0/12, 0%). We could not, however, predict complex malformation (0/8, 0%). Overall success was 90% (18/20) in the 20 ears observed for at least 1 year. In the 2 ears without improved hearing, the first had congenital cholesteatoma and no stapes superstructure, was treated with type IV tympanoplasty. The second had malleus, incus, and stapes fixation and discontinuity between the incus and stapes, and was treated with type III tympanoplasty and stapes mobilization. Preoperative diagnosis is difficult in mixed congenital auditory ossicular malformation, especially stapes footplate fixation, possibly requiring unexpected procedures, with a poor hearing outcome. Preoperative status must thus be evaluated precisely using hearing, tympanometry, acoustic reflex test, and CT. Temporal bone CT and external ear findings are useful in diagnosing middle-ear malformation. Subjects' informed consent should also be obtained due to the possible need for changing procedure based on findings during surgery. (author)

  15. Possible association between acetazolamide administration during pregnancy and multiple congenital malformations

    2016-01-01

    Congenital malformations might occur because of environmental or genetic factors, and sometimes occur because of unknown causes. Acetazolamide is a carbonic anhydrase inhibitor that is used to treat idiopathic intracranial hypertension, glaucoma, and epilepsy. The use of acetazolamide has not been recommended for pregnant women because of reported teratogenic risks. Congenital malformations, such as ectrodactyly, syndactyly, cleft lip/palate, and retarded incisor teeth development, have been reported in experimental animals. However, tooth agenesis due to the use of acetazolamide has not been reported yet. Oligodontia is a severe type of tooth agenesis involving six or more congenitally missing teeth. The causes of oligodontia are attributed to environmental factors, such as irradiation, drugs, trauma, tumors, infection, genetic factors, or a combination. There is no credible evidence of undesirable effects of acetazolamide use in human pregnancy. However, we report a case of a 12-year-old Saudi boy who was exposed to maternal acetazolamide (1,000 mg/day) for treatment of idiopathic intracranial hypertension before pregnancy, during the first trimester, and throughout the pregnancy. This treatment might have resulted in some congenital malformations, such as ectrodactyly, syndactyly, and oligodontia. PMID:27143854

    Full Text Available OBJETIVO: Verificar a frequência e tipos de cardiopatias congênitas em uma amostra de pacientes portadores de espectro óculo-aurículo-vertebral (EOAV, tentando correlacionar a presença desta malformação com suas demais características clínicas e evolução. MÉTODOS: A amostra foi composta por 33 indivíduos, todos atendidos em um mesmo centro, no período de janeiro de 1975 a dezembro de 2007. Vinte e dois deles eram do sexo masculino e 11 do feminino e suas idades variaram de 1 dia a 17 anos. Todos apresentavam avaliação cariotípica normal por bandas GTG. Realizou-se uma coleta de dados referentes à sua história clínica, exame físico e resultado de avaliações complementares. RESULTADOS: Anormalidades cardíacas foram observadas em 13 pacientes (39,4%. Dessas, cinco (38,5% eram do tipo conotruncal, sendo o principal defeito a tetralogia de Fallot (n=2. Malformações não usuais identificadas incluíram o cor triatriatum e a dupla via de entrada de ventrículo esquerdo. Diferenças significativas entre as características clínicas do grupo com e sem cardiopatia foram verificadas somente em relação à idade na primeira avaliação, que foi mais baixa naqueles com malformações cardíacas. Cinco indivíduos foram a óbito, quatro deles portadores desses defeitos. CONCLUSÃO: Malformações cardíacas, em especial dos tipos conotruncal e septal, são frequentes entre pacientes com EOAV. A frequência encontrada em nosso estudo foi estatisticamente similar à da maior parte dos trabalhos descritos na literatura, que oscila de 18% a 58%. As cardiopatias congênitas também representam a principal causa de óbito desses indivíduos. Portanto, uma avaliação cardiológica, especialmente precoce, deveria ser sempre realizada nesses pacientes.OBJECTIVE: To verify the frequency and types of congenital heart defects in a sample of patients with oculo-auriculo-vertebral spectrum (OAVS, in an effort to correlate presence of these defects with other clinical characteristics and evolution. METHODS: The sample comprised 33 subjects, all attended in the same center, between January 1975 and December 2007. Twenty two of them were male and eleven female and their ages ranged from 1 day to 17 years. All presented normal karyotype by GTG-Banding. A data collection related to their clinical history, physical examination and result of complementary evaluations was performed. RESULTS: Cardiac abnormalities were observed in 13 patients (39.4%. Of these defects, 5 (38.5% were conotruncal, tetralogy of Fallot being the main malformation (n=2. Unusual anomalies identified included cor triatriatum and double inlet left ventricle. Significant differences among the clinical characteristics of the group with and without heart defect were only verified in relation to age at first evaluation that was lower in subjects with cardiac malformations. Five patients died, four of them, bearers of congenital heart defects. CONCLUSION: Cardiac malformations, mainly conotruncal and septal defects, are frequent among patients with OAVS. Frequency found in our study was statistically similar to the majority of works described in literature where it ranged from 18 to 58%. Congenital heart defects also represent the main cause of death of these subjects. Thus, a cardiac evaluation should always be performed in these patients, especially at an early age.

  2. Congenital cystic adenomatoid malformation of the lung: hazards of delayed diagnosis.

    LENUS (Irish Health Repository)

    Collins, Anne M

    2012-02-01

    Congenital cystic adenomatoid malformation is a rare pulmonary developmental anomaly, which typically manifests in neonates and infants. Presentation in adulthood is uncommon, with <60 cases reported in the literature. The majority of cases involve one lobe only. We report a case of type 1 congenital cystic adenomatoid malformation in an adult presenting with a respiratory tract infection and haemoptysis. At thoracotomy, complex cystic masses were noted in the right upper and lower lobes. Lung-sparing surgery, in the form of two segmentectomies and a non-anatomical resection, was performed in order to avoid pneumonectomy. Such presentations may be problematic as potentially incomplete resections may increase the risk of complications and malignant transformation. This suggests the importance of appropriate clinical and radiological follow up.

  3. A link between solar events and congenital malformations: Is ionizing radiation enough to explain it?

    CERN Document Server

    Overholt, A C; Atri, D

    2015-01-01

    Cosmic rays are known to cause biological effects directly and through ionizing radiation produced by their secondaries. These effects have been detected in airline crews and other specific cases where members of the population are exposed to above average secondary fluxes. Recent work has found a correlation between solar particle events and congenital malformations. In this work we use the results of computational simulations to approximate the ionizing radiation from such events as well as longer term increases in cosmic ray flux. We find that the amounts of ionizing radiation produced by these events are insufficient to produce congenital malformations under the current paradigm regarding muon ionizing radiation. We believe that further work is needed to determine the correct ionizing radiation contribution of cosmogenic muons. We suggest that more extensive measurements of muon radiation effects may show a larger contribution to ionizing radiation dose than currently assumed.

  5. Case-control study of congenital malformations and occupational exposure to low-level ionizing radiation

    International Nuclear Information System (INIS)

    In a case-control study, the authors investigated the association of parental occupational exposure to low-level external whole-body penetrating ionizing radiation and risk of congenital malformations in their offspring. Cases and controls were ascertained from births in two counties in southeastern Washington State, where the Hanford Site has been a major employer. A unique feature of this study was the linking of quantitative individual measurement of external whole-body penetrating ionizing radiation exposure of employees at the Hanford Site, using personal dosimeters, and the disease outcome, congenital malformations. The study population included 672 malformation cases and 977 matched controls from births occurring from 1957 through 1980. Twelve specific malformation types were analyzed for evidence of association with employment of the parents at Hanford and with occupational exposure to ionizing radiation. Two defects, congenital dislocation of the hip and tracheoesophageal fistula, showed statistically significant associations with employment of the parents at Hanford, but not with parental radiation exposure. Neural tube defects showed a significant association with parental preconception exposure, on the basis of a small number of cases. Eleven other defects, including Down syndrome, for which an association with radiation was considered most likely, showed no evidence of such an association. When all malformations were analyzed as a group, there was no evidence of an association with employment of the parents at Hanford, but the relation of parental exposure to radiation before conception was in the positive direction (one-tailed p value between 0.05 and 0.10). Given the number of statistical tests conducted, some or all of the observed positive correlations are likely to represent false positive findings. 30 references

  6. Giant congenital malformation of the perirectal plexus in computed tomography imaging – case report

    International Nuclear Information System (INIS)

    Congenital arteriovenous malformation (AVM) in the pelvic area is uncommon in males. The described case is of a giant lesion of this type that caused recurrent hemorrhaging in the lower part of the gastrointestinal tract. Preliminary diagnosis of vascular pathology was made on the basis of an endoscopic examination that revealed numerous pulsating protuberances of the rectal wall, in which blood flow was identified by means of transrectal ultrasonography. Complementing the diagnostics with a CT revealed a considerable extent of malformation, as well as its morphology and anatomical relations with the surrounding tissues. Following a two-year follow-up period, the malformation did not progress or demonstrate any intensification of clinical symptoms, therefore the patient continues to undergo conservative treatment

  9. Prevalence and pattern of congenital malformations among neonates in the neonatal unit of a teaching hospital

    International Nuclear Information System (INIS)

    Objective: To determine the prevalence and pattern of congenital malformations among neonates in a teaching hospital. Methods: The prospective hospital-based study was conducted over a period of 18 months in the neonatal unit of Combined Military Hospital, Kharian, from September 2011 to February 2013. All neonates from newborn to 28 days of age admitted to the unit irrespective of their condition comprised the study population. Neonatal examination was done by the Registrar at the time of admission followed by neonatologist/paediatrician. Information regarding gender, weight, gestational age, mode of delivery, consanguinity, maternal age, antenatal visit record and family history were recorded on a predesigned proforma. After clinical examination, if required, relevant investigations like ultrasonography, radiology, echocardiography, laboratory and genetic studies were done to confirm diagnosis. Data was statistically analysed by using SPSS 20. Results: Out of 3,210 total admissions, 226 (7%) neonates were congenitally malformed. Of them, 130 (57.52 %) were male and 96 (42.47 %) females. Among different body systems affected, anomalies related to the central nervous system were 46(20.35%) musculoskeletal 42(18.58%), genitourinary 34 (15.04%), cardiovascular system 30 (13.27%), ear, eye, face, neck 27(11.94%), digestive system 19 (8.40%), syndromes and skin 14 (6.19%) each. Conclusion: Congenital Malformations are not rare in our community and central nervous system is the most commonly affected system. Healthcare managers must stress upon primary prevention in the form of vaccination, nutrition and drugs to decrease preventable share of congenital malformations. (author)

    Isolated systemic supply to the normal lung is a rare congenital anomaly, first described by Hurber in 1777. Many cases have since been published, diagnoses being made by necropsy, surgery, or more recently by angiography. However, only one case in the literature has been studied by CT and the description of the findings were schematic. The CT findings in two patients with this rare malformation are presented. In both cases CT provided sufficient data for the diagnosis. (author). 26 refs.; 2 figs.

  14. Embolization of Uterine Arteriovenous Malformations Associated with Cyanotic Congenital Heart Disease

    International Nuclear Information System (INIS)

    Uterine arteriovenous malformation (AVM) is a rare cause of vaginal bleeding and miscarriage. We report two cases of uterine AVMs in patients with a history of complex congenital heart disease, an association that has not been previously described. Both patients were treated by selective uterine artery embolization, a minimally invasive therapy that has revolutionized the management of uterine AVMs, thus offering an alternative to conventional hysterectomy.

    Full Text Available Objective: To determine the frequency of congenital heart defects (CHD in children with gastrointestinal malformations (GISM and mortality rates in patients with GISM. Methods: Two hundred and forty two consecutive children patients with GISM followed up in Pediatric Surgery Clinics of our hospital were examined for cardiovascular anomaly by the Department of Pediatric Cardiology, and the CHD incidence was investigated by examining the records of the patients retrospectively. Chi-square test was used for the statistical analysis of data. Results: Two hundred and forty two patients with gastrointestinal system malformations were included in the study. Of 242 patients, 135 (55.8% were male and 107 (44.2% were female, and their age range was 0-15 years. The most frequent GISM were anorectal malformations (43.2%, atresia involving stomach, ileum or colon (21% and esophageal atresia/tracheoesophageal fistula (18.3%. Congenital heart defects were observed in 28.5% of the participants. The most frequent defects were as follows; atrial septal defect (31 patients, 44.9% a, ventricular septal defect (17 patients, 24.6% and patent ductus arteriosus (5 patients, 7.2%. There was no significant difference (p>0.05 in mortality rate in patients with CHD (16.7% and without CHD (13.3% undergoing operations for GISM. Conclusion: We would like to emphasize the importance of the earliest possible cardiological evaluation of all patients with gastrointestinal system malformations.

  17. Clinical and neuroimaging profile of congenital brain malformations in children with spastic cerebral palsy

    International Nuclear Information System (INIS)

    Purpose: Analysis of the incidence of congenital brain malformations in children with spastic cerebral palsy (CP) in a hospital based study. Material and Methods: The present study included 74 boys and 56 girls with spastic tetraplegia, diplegia, and hemiplegia CP. Magnetic resonance imaging MRI findings were analyzed in children with CP. Results: Significant abnormalities relevant to the CP were evident on MRI in 124 (95.3%) subjects. Periventicular leukomalacia (PVL) was detected more frequently in children with spastic diplegia than in patients with tetraplegia or hemiplegia. Cerebral atrophy was found more often in the tetraplegic group compared to the diplegic patients. Porencephalic cysts were detected more often in children with spastic hemiplegia. Congenital brain anomalies were evident in 15 (10.7%) children with spastic CP. Brain malformations included: schizencephaly (5), agenesis corpus callosum (4), polymicrogyria (2), holoprosencephaly (2) and lissencephaly (2). Intractable epilepsy and mental retardation were observed more often in children with brain anomalies. Twelve patients with congenital brain malformations were born at term and three born at preterm. Conclusions: Neuroimaging results in children with CP may help determine the etiology and make better prognosis of CP. (authors)

  18. Spontaneous pneumothorax in a teenager with prior congenital pulmonary airway malformation

    2014-01-01

    Full Text Available Congenital pulmonary airway malformation (CPAM, previously referred to as congenital cystic adenomatoid malformation (CCAM, is a developmental malformation of the lower respiratory tract and the most commonly reported congenital lung lesion. Affected patients typically present with respiratory distress in the neonatal period from expanding cysts and resulting compression of surrounding lung parenchyma. However, some patients also remain asymptomatic until later in life. In this report, we present a case of CPAM requiring emergent left lower lobectomy at the first day of life that remained asymptomatic until the patient developed a spontaneous pneumothorax 18 years later. Our patient's presentation with an isolated spontaneous pneumothorax at age 18 does not appear to have been previously reported. In addition, there are several aspects of this case that represent atypical features of CPAM. After an extensive literature search, few reports exist describing any long-term complications of CPAM following neonatal lobectomy. Chest imaging in our patient demonstrated residual left basilar bullae and there was a moderate fixed obstructive/restrictive defect on pulmonary function testing. His risk for recurrent pneumothorax or infectious complications is unknown based on minimal published information on long-term outcomes or complications in patients with resected CPAM lesions. We conclude that follow up of all CPAM patients should include an evaluation for evidence of residual lung disease both with spirometric testing and chest imaging. Furthermore, concern for infectious complications or symptomatic obstructive lung disease should likewise be considered.

    Congenital anorectal malformation (ARM) is one of the most common gastrointestinal congenital diseases, accounting for 1/4 in digestive tract malformation, and is one of the congenital malformations in routine surveillance by the World Health Organization. Because of the variety of risk factors and the complexity of the pathological changes, etiology of ARM is still not clear. It is mostly considered that ARM is resulted from hereditary factors and environmental factors in the development of embryogenesis. Through animal experiments, scholars have found that Hox, Shh, Fgf, Wnt, Cdx and TCF4, Eph and ephrin play crucial role during the development of digestive tract. When the genes/signaling pathway dysfunction occurs, ARM may happen. In addition, ARM is related to the external factors in pregnancy. Because of the complexity of related factors in the development of human embryogenesis, the research progress of human ARM is very slow. This paper reviews relevant literatures in genetic factors and environmental factors, in order to provide the theoretical basis for the treatment and prevention of ARM. PMID:26797848

    Bovine neosporosis, caused by Neospora caninum is a leading cause of abortion in cattle. We postulated that neosporosis could lead to fetal death and mummification. Fifteen mummified fetuses were tested by polymerase chain reaction (PCR) for the mutation in the bovine SLC35A3 gene that causes complex vertebral malformation (CVM) and the pNC-5 gene which identifies N. caninum infection. DNA was extracted from the mummified fetuses and the sex of the mummies was determined by PCR. The CVM mutat...

    Factor XI Deficiency (FXID) is caused by imperfect insertion of poly adenine which is resulted in introduction of premature stop codon in FXI gene. Substitution of guanine into thymine in SLC35A3 gene caused Complex Vertebral Malformation (CVM). The research was aimed to detect the presence or absence of a genetic defect mainly CVM using SLC35A3 gene and FXID using FXI gene in Indonesian Bali cattle. The presence of this genetic defect may have a significant economic impact on the breeding p...

  3. Congenital frontonasal masses: developmental anatomy, malformations, and MR imaging

    International Nuclear Information System (INIS)

    The newborn, infant, or young child who presents with a midline frontonasal mass often poses a diagnostic challenge to the clinician. The most pressing issue is whether the mass extends intracranially. The development of the frontonasal region or anterior neuropore is complex. Aberrant embryogenesis leads to three main types of anomalies: nasal dermal sinus, anterior cephalocele, and nasal glioma. Understanding the developmental anatomy of the anterior neuropore and postnatal maturation will serve the radiologist well when it comes to imaging frontonasal masses. Pitfalls particularly common to CT imaging interpretation include the evolving ossification of the frontal, nasal and ethmoid bones in the first year of life, morphology and size of the foramen cecum, and the natural intumescence of the anterior nasal septum. Determination of the presence of a connection between the frontonasal mass and the anterior cranial fossae is crucial in the imaging assessment and clinical management. In the case of the nasal dermal sinus, failure to appreciate the intracranial components of the malformation can lead to fatal meningitis. MR imaging is the modality of choice for assessing the pediatric frontonasal region. Its advantages include multiplanar imaging, distinguishing the interface among cartilage, bone, brain and fluid, diffusion imaging to detect epidermoid tumors, and the capacity to evaluate the brain for associated cerebral anomalies.

    Full Text Available Objective: Genitourinary anomalies in patients with imperforate anus are a frequent source of significant morbidity. Variability of reports on the incidence of associated anomalies with imperforate anus mandates investigation on this issue. Material & Methods: The case records and imaging studies of 105 patients who underwent surgery for imperforate anus over a 10-year period are retrospectively reviewed. Voiding cystouretherography, intra venous pyelography (IVP and ultrasound were performed in patients with intermediate or high level anorectal lesions. Findings: During 10 years, there were 48 boys (45.7% and 57 girls (54.3% with imperforate anus. Genitourinary anomalies were seen in 34 (48.6% patients with intermediate or high level anorectal lesions. Eighteen of them (52.9% were shown to have vesicouretral reflux, only 6 of them required surgical correction. Vesicoureteral reflux was the most prominent urologic anomaly; other anomalies such as ureteropelvic junction (UPJ stenosis, hydronephrosis, hypospadias, renal agenesis and undescended testis were seen in these series. Conclusion: Patients with anorectal malformations should be evaluated for urinary tract and spinal anomalies.

    Medical syndromes have often been represented in fine arts, but rarely have clinical diagnoses been discussed in comic book characters. Since their first appearance in Europe in the middle of the 19th century and in America in 1895, comic books have been considered as "the 9th art". In many comic books, the appearance and/or the behavior of central or support characters are suggestive of already well-defined medical disorders. The representation of five particular groups or clinical features: mental retardation, abnormal stature, abnormal hair, obesity, and cranial malformations is discussed from mostly European comic series. Whether comic authors intended to describe specific clinical entities while drawing their characters or whether such situations appeared by mere luck, is open to debate. In many series from the first half of the 20th century characters with remarkable clinical features were also painted as psycho-social deviants. Such stereotypes are found much less frequently nowadays. Writers of comic books, realizing the major impact of their work especially in adolescent age groups, have increasingly been using their series to actually promote issues of equity and well being for physically or mentally impaired people.

    We report on 2 brothers with both fragile X and VACTERL-H syndrome. The first sibling, age 5, had bilateral cleft lip and palate, ventricular septal defect, and a hypoplastic thumb. The second sibling, age 2{1/2}, had a trachesophageal fistula, esophageal atresia, and vertebral abnormality. High-resolution chromosome analysis showed a 46,XY chromosome constitution in both siblings. By PCR and Southern blot analysis, the siblings were found to have large triplet repeat expansions in the fragile X gene (FMR 1) and both had methylation mosaicism. Enzyme kinetic studies of iduronate sulfatase demonstrated a two-fold increase in activity in the first sib as compared to the second. Possible mechanisms through which the fragile X mutation can cause down-regulation of adjacent loci are discussed. 24 refs., 4 figs.

    In several patients, intellectual disability and/or congenital malformation may be attributed to chromosomal changes. In this study, we conducted an array-CGH test of 200 patients from the Northeast of Brazil with intellectual disability and/or congenital malformation. Blood samples were collected from the proband and from their parents when possible. DNA was extracted and investigated using the array-CGH test. Findings were evaluated for the pathogenicity in databases of benign and pathogenic changes (ISCA, UCSC, DGV, and DECIPHER). Forty-seven copy number variations (CNVs) were identified in 43/200 (21.5%) patients, including 25/98 (25.5%) in males and 22/102 (21.57%) in females. We considered 33 of these to be clinically significant, reaching a diagnosis rate of 16.5%. The sizes of the CNVs varied from 102 kb to 24 Mb in deletions and from 115 kb to 140 Mb in duplications. In 10/47 (21.3%) patients, the rearrangement involved a sex chromosome. Thirty-nine patients had one chromosomal aberration, while 2 concomitant abnormalities were detected in 4 patients. Ten of 47 CNVs (21.3%) were > 5Mb in size. Fifteen patients had CNVs related to known syndromes. This research highlights the contribution of submicroscopic chromosomal changes to the etiology of intellectual disability and/or congenital malformation, particularly the implication of chromosomal abnormalities detected using an array-CGH test, with a high rate of 16.5%. Thus, our results support the use of array-CGH replacing standard karyotype as the first-tier cytogenetic diagnostic test for patients with multiple congenital anomalies and/or intellectual disability.

    Congenital malformations, such as neural tube defects (NTDs) and congenital heart disease (CHD), cause significant fetal mortality and childhood morbidity. NTDs are a common congenital anomaly, and are typically induced by higher maternal homocysteine (Hcy) levels and abnormal folate metabolism. The gene encoding methionine synthase reductase (MTRR) is essential for adequate remethylation of Hcy. Previous studies have focused on the coding region of genes involved in one-carbon metabolism, but recent research demonstrates that an allelic change in a non-coding region of MTRR (rs326119) increases the risk of CHD. We hypothesized that this variant might contribute to the etiology of NTDs as well, based on a common role during early embryogenesis. In the present study, 244 neural tube defect cases and 407 controls from northern China were analyzed to determine any association (by χ (2) test) between rs326119 and disease phenotypes. Significant increased risk of anencephaly was seen in MTRR variant rs326119 heterozygote (het) and homozygote (hom) individuals [odds ratios (OR)het = 1.81; ORhom = 2.05)]. Furthermore, this variant was also a risk factor for congenital malformations of the adrenal gland (OR = 1.85), likely due to multiple systemic malformations in the NTDs case population. Our present data indicate that the rs326119 non-coding variant of MTRR has a pleiotropic effect on the development of multiple tissues, especially during early stages in utero. This suggests the allelic state of MTRR is a significant clinical factor affecting Hcy levels and optimal folic supplementation. PMID:26045171

  9. Congenital heart malformations induced by hemodynamic altering surgical interventions

    2014-08-01

    Full Text Available Embryonic heart formation results from a dynamic interplay between genetic and environmental factors. Blood flow during early embryonic stages plays a critical role in heart development, as interactions between flow and cardiac tissues generate biomechanical forces that modulate cardiac growth and remodeling. Normal hemodynamic conditions are essential for proper cardiac development, while altered blood flow induced by surgical manipulations in animal models result in heart defects similar to those seen in humans with congenital heart disease. This review compares the altered hemodynamics, changes in tissue properties, and cardiac defects reported after common surgical interventions that alter hemodynamics in the early chick embryo, and shows that interventions produce a wide spectrum of cardiac defects. Vitelline vein ligation and left atrial ligation decrease blood pressure and flow; and outflow tract banding increases blood pressure and flow velocities. These three surgical interventions result in many of the same cardiac defects, which indicate that the altered hemodynamics interfere with common looping, septation and valve formation processes that occur after intervention and that shape the four-chambered heart. While many similar defects develop after the interventions, the varying degrees of hemodynamic load alteration among the three interventions also result in varying incidence and severity of cardiac defects, indicating that the hemodynamic modulation of cardiac developmental processes is strongly dependent on hemodynamic load.

    An outbreak of congenital abnormalities occurred in sheep at San Angelo, Texas, between December 1986 and February 1987. Of 360 lambs born, 19.2% had arthrogryposis or other musculo-skeletal problems and hydranencephaly (AGH), and the total neonatal loss was 25.6%. In 1987, all ewes that were tested with AGH lambs had antibody to Cache Valley virus (CVV), whereas 62% of the ewes with normal lambs had CVV-specific antibody. Pre-colostral serum samples from AGH lambs had neutralizing antibody to CVV. An increase in prevalence of CVV-specific antibody, from 5% during the spring of 1986 to 63.4% during the winter of 1987, occurred during a time that included the gestation of these affected lambs, as well as a period of increased rainfall. The isolation of a CVV-related strain from a sentinel sheep in October 1987 confirmed the continued presence of this virus in the pasture where this outbreak occurred and provided a recent field strain for future studies.

  11. Early fetal growth delay detected by ultrasound marks increased risk of congenital malformation in diabetic pregnancy.

    Pedersen, J F; Molsted-Pedersen, L

    1981-01-01

    Ninety-nine insulin-dependent diabetic women with regular menstrual histories were examined by ultrasonic scanning in the seventh to 14th weeks of pregnancy. As judged by the crown-rump length 38 fetuses were smaller than normal. The term early growth delay is suggested for this phenomenon. Nine fetuses had major congenital malformations, and seven of them were smaller than normal in early pregnancy (p less than 0.02). The risk of fetal malformation in diabetic pregnancy increases with the severity of the diabetes. Early fetal growth delay is apparently another risk marker, in this series indicating a risk of 18% (7/38). The combination of severe maternal diabetes (White's classes D and F) and early growth delay yielded a risk of major congenital malformation of 27% (6/22). These observations suggest a common mechanism behind early growth delay and induction of abnormal embryogenesis (and maybe even fetal death). The mechanism is unknown but probably influenced by the quality of regulation of diabetes. PMID:6788283

    This report describes a cohort study of over 5000 infants and their mothers who participated in a cord blood serosurvey designed to examine the relationship between maternal exposure to Lyme disease and adverse pregnancy outcome. Based on serology and reported clinical history, mothers of infants in an endemic hospital cohort are 5 to 20 times more likely to have been exposed to B. burgdorferi as compared with mothers of infants in a control hospital cohort. The incidence of total congenital malformations was not significantly different in the endemic cohort compared with the control cohort, but the rate of cardiac malformations was significantly higher in the endemic cohort [odds ratio (OR) 2.40; 95% confidence interval (CI) 1.25, 4.59] and the frequencies of certain minor malformations (haemangiomas, polydactyly, and hydrocele), were significantly increased in the control group. Demographic variations could only account for differences in the frequency of polydactyly. Within the endemic cohort, there were no differences in the rate of major or minor malformations or mean birthweight by category of possible maternal exposure to Lyme disease or cord blood serology. The disparity between observations at the population and individual levels requires further investigation. The absence of association at the individual level in the endemic area could be because of the small number of women who were actually exposed either in terms of serology or clinical history. The reason for the findings at the population level is not known but could be because of artifact or population differences. PMID:7479280

    International Nuclear Information System (INIS)

    Congenital lung abnormalities are a heterogeneous group of alterations in lung development, and many of them are asymptomatic, but is important to know, they must enter the differential diagnosis of patients respiratory distress syndrome. Some of these lesions can coexist, the point where the pulmonary sequestration may present with adenomatoid malformation cystic type II in over 50% of cases. Although the final diagnosis for this histological type of injury is, images play an important role for initial approach. Natural history of these malformations depends lung the size of the lung mass and physiological problem that this causes. The CT multidetector computed expanded knowledge of lung anatomy and improves visualization of the tracheobronchial tree in the pediatric population.

  14. Congenital malformations among live births at arvand hospital, ahwaz, iran - a prospective study

    International Nuclear Information System (INIS)

    The aim of the study was to determine the profile of congenital malformations (CM) among live births at Arvand hospital, in Ahwaz city. In this prospective study all of the neonates born at Arvand hospital in Ahwaz from 2004 to 2006 were registered. Stillbirths and those who died in a few hours after birth were excluded and finally 4660 newborns were enrolled. Of the 4660 live births 94 (20.2/1000) had at least a CM. The predominant systems involved were musculoskeletal (7.9/1000), followed by genitourinary (7.1/1000), central nervous (2.4 /1000), digestive (1.1/1000) and chromosomal anomalies (0.9/1000). Although the frequency of malformations in the study was approximately similar to other investigations, if we include abortions, stillbirths and if we used screening tests and genetic studies, this rate was more than 20.1/1000.

    Congenital scoliosis associated with split cord malformation raises the issue on how to best manage these patients to avoid neurologic injury while achieving satisfactory correction. We present the case of a 12-year-old girl who first presented when she was 11-year old with such combination but without much physical handicap or neurological deficit. The corrective surgery offered at that time was refused by the family. She again presented after 1 year with documented severe aggravation of the curve resulting in unstable walking and psychological upset. Her imaging studies showed multiple malformations in lower cervical and thoracic spine and a split cord malformation type 2 (fibrous septum with diplomyelia) at the apex of the deformity. A one-stage correction was deemed neurologically too risky. We therefore performed during a first stage a thoracotomy with anterior release. This was followed by skeletal traction with skull tongs and bilateral femoral pins. After gradual increase in traction weights a reasonable correction was achieved without any neurological deficit, over the next 10 days. A second-stage operation was done on the 11th day and a posterior instrumented fusion was performed. Post-operative recovery was uneventful and there were no complications. She was discharged with a Boston Brace to be worn for 3 months. At 2-year follow-up the patient outcome is excellent with excellent balance and correction of the deformity. In this grand round case, we discuss all the different option of treatment of congenital scoliosis associated with split cord malformation. In a medical environment where spinal cord monitoring is lacking, we recommend an initial release followed by skull and bifemoral traction over several days to monitor the neurologic status of the patient. Once optimal correction is achieved with the traction, a posterior instrumentation can be safely done. PMID:19626347

  16. Prevalence at birth of congenital malformations in communities near the Hanford site

    International Nuclear Information System (INIS)

    The authors examined the prevalence of congenital malformations among births in Benton and Franklin counties, in southeastern Washington State, from 1968 through 1980. The Hanford Site is in this area and serves as a major employer. In addition, various agriculturally and chemically related activities are in the area. Hospital and vital records were used to identify 454 malformation cases among 23,319 births; this yielded a malformation rate of 19.6 per 1000 births, a rate similar to those reported in other studies. The rates of specific malformations ascertained during the first year of life were compared with combined rates from the states of Washington, Oregon, and Idaho from the Birth Defects Monitoring Program. Among defects that would be expected to be comparably ascertained, a statistically significant elevated rate of neural tube defects was observed (1.72 per 1000 births vs. 0.99 per 1000). Rates of cleft lip were significantly lower in Benton and Franklin counties than in the Birth Defects Monitoring Program (0.59 per 1,000 vs. 1.17 per 1000). For congenital heart defects, pyloric stenosis, and Down syndrome, which are often not diagnosed in the newborn period, Birth Defects Monitoring Program data did not offer appropriate comparisons. The rates of these defects did not appear to be elevated in relation to rates found in other relevant populations. When rates of neural tube defects were compared with those in populations other than the Birth Defects Monitoring Program, the Benton and Franklin county rates were still considered to be elevated. The increased bicounty rate cannot be explained by employment of the parents at Hanford or by the impact of plant emissions on the local population

    Full Text Available Purpose: To present a single-center experience with 25 cases of bronchopulmonary malformations and the review the literature. Materials and Methods: We conducted a retrospective analysis of the medical records of patients with congenital bronchopulmonary malformations who were operated between July 1997 and July 2007 in our institute; we examined the modes of presentations, management, and outcome. Outcome of all patients was assessed over a short follow-up period (average 1.8 months. Results: Out of 25 patients, 18 (72% were male and 7 (28% were female. Age of patients ranged from 1 day to 11 years. The histopathological diagnosis was congenital cystic adenomatoid malformations [CCAM; n = 14 (56%], congenital lobar emphysema [CLE; n = 5 (20%], pulmonary sequestrations [PS; n = 3 (12%], and bronchogenic cysts [BC; n = 3 (12%]. Antenatal diagnosis was available in only 2 (8% patients. The common presenting symptoms were respiratory distress and chest infections. Lobectomy was the procedure of choice . Mortality was 16% (n = 4; M: F = 3: 1. Two patients died because of overwhelming sepsis, one from compromised cardiac function, and one from aspiration which might possibly have been prevented. Conclusion: Patients with progressive respiratory distress due to these anomalies may require urgent surgical intervention regardless of age. The surgical outcome is favorable, with manageable complications. Plain x-ray chest and CT of thorax are usually sufficient for diagnosis and planning of treatment. Pathological diagnosis may differ from the imaging diagnosis. Mortality is found to be more in neonates. Apart from initial stabilization, resection of lesion and careful postoperative care is necessary to reduce mortality and morbidity.

  18. Unusual signal intensity of congenital pulmonary airway malformation on fetal magnetic resonance imaging

    International Nuclear Information System (INIS)

    Congenital pulmonary airway malformation (CPAM) is classified into pathologically different types. These types are sometimes distinguishable by fetal lung MRI and are usually observed as higher-signal lesions on T2-weighted images than normal lung. We describe a case of unusual CPAM resembling neoplasms, with a lower signal than is found in normal lung. Histopathology showed a large number of mucogenic cells but found no evidence that could explain this feature on fetal MRI. An unusual low-signal mass associated with a pulmonary cyst in fetal lung on MRI may suggest an unusual type 1 CPAM. (orig.)

    Full Text Available Interstitial lung diseases (ILD are a heterogeneous group of pulmonary disorders that are relatively rare in the pediatric population. These diseases are characterized by impaired gas exchange and typically manifest with diffuse infiltrates on radiographs. Pulmonary interstitial glycogenosis (PIG has recently been identified as an ILD affecting neonates and infants that manifests diffusely throughout the lungs by imaging, has non-specific clinical features, and usually has a favorable outcome in the absence of significant comorbid conditions. We report two cases of PIG that presented with focal radiographic abnormalities, leading to erroneous diagnoses of congenital pulmonary airway malformations and pulmonary resection.

    2004-09-01

    Full Text Available Complex vertebral malformation (CVM is an autosomal recessive inherited defect in the Holstein breed. It causes intra-uterine mortality through the entire gestation period leading to repeat breeding and involuntary culling of cows and thereby economic losses. The defect was first reported in Denmark in 1999 and a direct DNA test for the defect has been available since February 2001. The aim of this study was to investigate if Holstein bulls heterozygous for the CVM gene had reduced reproductive performance, measured as non-return rate (NRR and in a daughter fertility index. All genotyped Swedish Holstein bulls born between 1995 and 1999 were included. Altogether 228 bulls were analysed, of which 53 bulls, i.e. 23%, were confirmed CVM carriers. A statistically significant difference between carriers and non-carriers in the relative breeding value for NRR was observed for 168 days NRR (101.1 0.9 vs. 103.1 0.6, p

  3. [Information should be given on consanguinity as a risk factor for congenital malformations].

    2014-01-01

    In the Born in Bradford study, an increased risk for congenital anomalies was found in the Pakistani subpopulation of Bradford, where cousin marriage is relatively frequent. While consanguinity may be associated with a risk for congenital malformations, it does not prove a causal relationship. Whatever the case, high perinatal mortality as well as the high prevalence of congenital anomalies are good reasons for implementing the knowledge on reproductive risks that has been available for many years. Well-known risk factors include higher maternal age, that was associated with congenital anomalies in the British mothers. Further research in an intervention study may provide more data on whether the associations found are causal. Implementing preconception care should involve primary care physicians, who need both facilities and training. In the Netherlands, the high perinatal mortality, especially in some big cities, could profit from similar interventions. Dutch primary care physicians consider it their responsibility to discuss consanguinity with patients, although there is some reluctance because of anticipated religious and social value conflicts. Without information reaching the target populations, they may lack awareness and will not ask for information themselves. People from Dutch migrant groups would prefer to be informed about reproductive risks of consanguinity by their primary care physicians. PMID:24397975

  5. Clinical application of the amplatzer vascular plug in the embolization of vascular malformations associated with congenital heart diseasee

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical efficacy of percutaneous transcatheter embolization by using Amplatzer vascular plug (AVP) for the treatment of vascular malformations associated with congenital heart diseases. Methods: During the period of June 2006-June 2008, 12 patients with congenital heart disease accompanied by vascular malformations received transcatheter occlusion of the anomalous vessels with AVP. The vascular malformations included solitary or multiple saccular pulmonary arteriovenous malformation (n = 7), coronary artery fistula (n = 2) and major aortopulmonary collaterals concomitant with severe Fallot' s tetralogy (n = 3). All patients were screened with transthoracic echocardiography (TTE) and thoracic CT angiography (CTA), and all the diagnoses were confirmed by routine cardioangiography. Results: Transcatheter occlusion of vascular malformations with AVP was successfully accomplished in all 12 patients. An angiographic check immediately after the procedure showed that complete occlusion was obtained in all patients and no embolism,migration or residual shunt were seen. Sixteen anomalous vessels were occluded. The mean internal diameter of these vessels was (5.2 ± 1.9) mm,while the mean diameter of AVP used was (9.2 ± 2.4) mm. After the operation (mean 3 months), the follow-up echocardiography and/or thoracic CT angiography showed that in all patients the occlusion remained in satisfactory condition and no residual shunt was found. Conclusions: Percutaneous transcatheter closure of congenital vascular malformations with AVP is technically feasible and clinically effective, this treatment can markedly improve patient's living quality and it is well worth extending its clinical application.

    Full Text Available A congenital recto - vaginal fistula is a high type of ARM characterized by the abnormal connection of the rectum to the vagina . High type anorectal malformations (ARM are extremely rare variants in the spectrum of anorectal deformities. Delayed presentation of a patient with high anorectal malformation is rare. The unusually rare and late presentation of this case highlights the need to generate awareness of the general population, the medical fraternity about common congenital anomalies and the need for efficient referral system to a tertiary centre.

    Congenital intrahepatic arterioportal venous malformations (APVM) are uncommon lesions. A congenital intrahepatic APVM found incidentally in a 51 -year-old man during pre-operative aortography for an abdominal aortic aneurysm is reported here. This was successfully treated by transcatheter embolization of the involved hepatic artery prior to surgical repair of the aortic aneurysm. A 51-year-old smoker was admitted for pre-operative aortography of an abdominal aortic aneurysm (AAA). Liver function tests showed a mildly elevated alkaline phosphatase. There was no previous history of liver disease or trauma. Aortography demonstrated a large infra-renal AAA measuring 10 cm in diameter and 20 cm in length. The coeliac axis was noted to be grossly dilated with tortuous veins seen to the right side of the lower thoracic spine on delayed images. Coeliac angiography revealed a dilated intrahepatic vascular abnormality in the left lobe of the liver with late opacification of the portal vein. Contrast abdominal CT demonstrated the AAA and the dilated coeliac axis feeding a large vascular malformation in the lateral aspect of the left lobe of the liver. The arterial inflow was via the left hepatic artery and a large vein was seen leading into the left portal vein. Endoscopy showed no oesophageal varices. (authors). 11 refs., 7 figs.

  10. Congenital cystic adenomatoid malformations (CCAM) - prenatal MRI diagnosis: a case report

    International Nuclear Information System (INIS)

    Full text: Congenital Cystic Adenomatoid Malformation/CCAM (recently termed Congenital Pulmonary Airway Malformation/CPAM) is a rare lung lesion that is believed to result from a cessation of bronchiolar maturation with overgrowth of mesenchymal elements. The differential diagnosis of a mass in the fetal thorax includes CCAM/CPAM, congenital diaphragmatic hernia, and pulmonary sequestration. We present a case of CCAM/CPAM detected on prenatal ultrasound examination with prenatal magnetic resonance imaging (MRI) correlation. A multicystic lesion in the right hemithorax of the fetus was identified on ultrasound at 26th weeks of gestation which was slightly increasing in size on follow-up examinations. MRI was performed for further evaluation and selecting the appropriate management. On MRI the lesion was confined to the right middle lobe, consisting of a single large 3 cm cyst surrounded by multiple smaller cysts and compressed normal parenchyma of the upper and lower lobes of the right lung (type I, Stocker and al. classification). No mediastinal shift or other abnormalities to the contralateral lung were detected. No complications, such as hydrothorax or polyhydramnios were identified. Based on the MR findings postnatal surgical removal of the lung lesion was planned. Continuous weekly ultrasound follow-up examination was recommended. Improvements in magnetic resonance imaging (MRI) now permit diagnostic images of the fetus to be obtained. Ultrasound (US) remains vital in all aspects of fetal imaging but MR serves as a useful second line imaging test. MR imaging can provide excellent tissue contrast with more accurate analysis of the fetal anatomy and superior differentiation between the abnormalities and adjacent structures, thereby allowing early planning of pre- and postnatal management

    Congenital malformations and cerebral damage in early infancy cause complex morphological and clinical changes. Modern imaging techniques, and especially NMR, have provided deeper knowledge of these diseases in the past few years. Based on the neuroradiological findings, the book presents a complete picture of congenital malformations of the central nervous systems and cerebral damage in early infancy; it describes the underlying pathomechanisms, clinical symptoms and therapies. Neurologists and neuropaediatricians are enabled to diagnose malformations correctly and to develop optimal therapy strategies in cooperation with other medical disciplines. Neuroradiologists and radiologists, on the other hand, will find a manual for correct interpretation and differential diagnosis of their findings and a guide for interpreting the findings and deciding further therapeutic or diagnostic interventions.

    Full Text Available A 34-year-old patient learned that she was 7 weeks pregnant while she was using topical isotretinoin + erythromycin gel for acne treatment and referred to Izmir Katip Celebi University Teratology Information Service for information regarding the risk of teratogenicity. Systemic use of isotretinoin is well-known for its teratogenic effects and case reports suggesting possible teratogenic effects regarding topical exposure to retinoids in pregnancy exist in the literature. However, findings reported in four prospective controlled studies do not suggest an increased congenital malformation risk in case of inadvertent exposure during pregnancy. This manuscript aims to give a summary and evaluation of available data for counseling pregnant patients regarding the possible teratogenic risk of inadvertent topical isotretinoin exposure during pregnancy. It also aims to emphasize the importance of increasing communication between pregnant patients, clinicians and teratology information services for the benefit of mother and unborn.

    Congenital cystic adenomatoid malformation (CCAM) of the lung is one of the rarest causes of neonatal distress. The principal radiological sign of CCAM is an intrapulmonary mass of soft tissue density, containing cystic areas of different sizes and shapes. The mass usually compresses the rest of the affected lung and displaces the mediastinum and heart to the opposite side, compressing the lung which is often therefore hypoplastic. If CCAM is diagnosed in utero by ultrasound, the treatment of choice is surgery as soon as possible after birth, with good survival rates. Sixteen cases of CCAM are presented, one with bilateral disease, diagnosed at different times, and one with an associated prune belly syndrome, to be added to the 405 already reported in the literature, and their clinical, radiological and pathological features are described.

    Full Text Available Factor XI Deficiency (FXID is caused by imperfect insertion of poly adenine which is resulted in introduction of premature stop codon in FXI gene. Substitution of guanine into thymine in SLC35A3 gene caused Complex Vertebral Malformation (CVM. The research was aimed to detect the presence or absence of a genetic defect mainly CVM using SLC35A3 gene and FXID using FXI gene in Indonesian Bali cattle. The presence of this genetic defect may have a significant economic impact on the breeding program. The research of genetic defect was done mostly in dairy cattle, but there was no report for screening of genetic defect in Bali cattle. In this study, 303 fresh blood samples and 22 semen samples which were collected from Indonesian Bali cattle breeding center (BPTU HMT Denpasar, BPT HMT Serading West Nusa Tenggara and district Barru South Sulawesi and artificial insemination centre (BBIB Singosari and BIBD Baturiti were used for screening of FXID and CVM. The amplicons of FXI gene were obtained by using PCR and that for SLC35A3 gene were obtained by using PCR-RFLP method with PstI restriction enzyme. These PCR products were analyzed by using 2% agarose gels electrophoresis. All genotypes were confirmed by DNA sequencing to determine an allele mutant. The allele mutant was not found in all of the samples. The result of this study showed that CVM and FXID were not detected in Bali cattle from Indonesian Bali cattle breeding and artificial insemination centres.

  17. Prenatal diagnostics of congenital malformations, the most efficient way to decrease genetic consequences of Chernobyl accident

    International Nuclear Information System (INIS)

    Long-term study of the prevalence of congenital malformations (CM) in the population of Belarus, carried out by Belarus Institute for Hereditary Diseases, showed considerably increased, from 5.6% in 1980-1985 to 7.2% in 1986-1996, frequency of the anomalies found in embryos, increased number of malformations in induced abortuses and also the growth of CM in newborns, from 5 in 1983-1985 to 7.2 in 2001, in post-Chernobyl period. The highest raise was registered in the mostly contaminated with Cs-137 areas in the first post-Chernobyl years. There are various reasons for the observed increase, but they are still not clearly understood. Nutrition imbalance (deficit of vitamins, essential amino acids and soluble selenium), physoemotional stress, hormone imbalance, alcoholism and increased level of mutations due to additional exposure of the gonads of the residents of contaminated areas of the Republic can have some impact. Positive prevalence trend of multifactorial anomalies evidences multifactorial origin of the increased prevalence of embryonal anomalies. Both, increased prevalence of CM with great contribution of dominant mutations and the peak of Down's syndrome cases, recorded in January, 1987 with maximum in Gomel region, suggest mutation component. At present, the most efficient measures to prevent the birth of malformed children are prenatal diagnostics and vitamin supplement of the couples, who plan their pregnancy, and pregnant women in the first trimester. According to the conclusion, made by WHO experts, vitamin intake can considerably reduce many CM with multifactorial origin. Positive results can be achieved only if the problem is solved by the government, when vitamins are added to flour, cereals and bread. Prenatal diagnostics with subsequent termination of pregnancy, where incurable anomalies are found, contributes greatly to the reduction of the proportion of malformed newborns, irrespective of the factors, which caused the anomalies. Thus, in Belarus in the last 5 years about 500 pregnancies were terminated annually for genetic reasons. Over 100 pregnancies were terminated in Gomel region, which considerably reduced (by 1-3%) perinatal mortality, children's morbidity and disability. The number of children, born with the anomalies of the central nervous system, renal polycystosis and agenesis, omphalocele, reduction limb defects, is decreasing most considerably. The potentialities of prenatal diagnostics of CM are far from being used adequately in the Republic. With sufficient financing, present-day techniques allow prenatal diagnosing of 1000 cases instead of 600 diagnosed each year. The program will be productive, if prenatal biochemical screening and invasive prenatal procedures are financed regularly and interregional centres for prenatal diagnostics are created. These measures will not only reduce the proportion of children, born with congenital malformations, but increase the birth rate in Belarus, since the future mothers will not be scared to give birth to a malformed child, which is especially essential for the population exposed to radiation due to Chernobyl accident (authors)

    Full Text Available Objectives: The aims of this study were: to evaluate the prevalence of abdominal wall defects in the Polish population, to analyze temporal trends in the prevalence, to identify areas (clusters of high risk of abdominal wall defects, and to characterize, with respect to epidemiology, children with abdominal wall defects and their mothers in the area defined as a cluster. Material and Methods: We used isolated congenital malformations (gastroschisis Q79.3 and omphalocele Q79.2 according to the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10, the extended version data reported to the Polish Registry of Congenital Malformations (PRCM over the years 1998– 2008 based on the population of 2 362 502 live births. We analyzed 11 administrative regions of Poland with complete epidemiologic data. Results: Of 11 regions, 2 had a significantly higher standardized prevalence of isolated gastroschisis: Dolnośląskie (1.7/10 000 live births, p = 0.0052 and Śląskie (1.9/10 000 live births, p < 0.0001. Furthermore, within the region of Dolnośląskie, we defined a clear prevalence of the isolated gastroschisis cluster (p = 0.023. We comprehensively examined demographic and socio-economic risk factors for abdominal wall defects in this area, and we found that these factors failed to account for the cluster. Conclusions: We identified a distinct prevalence cluster for isolated gastroschisis, although a precise reason for the disease clustering in this region remains unknown. Cluster identification enables more focused research aimed at identification of specific factors with teratogenic effects.

    Full Text Available Abstract Background Estimated 17,000 neonates (≤ 28 days of age die in Vietnam annually, corresponding to more than half of the child mortality burden. However, current knowledge about these neonates is limited. Prematurity, asphyxia and congenital malformations are major causes of death in neonates worldwide. To improve survival and long term development, these vulnerable neonates need access to the specialized neonatal care existing, although limited, in lower middle-income countries like Vietnam. The aim of this study was to describe these conditions in a specialized Vietnamese hospital, compared to a Danish hospital. Methods We performed a comparative observational study of all neonates admitted to a tertiary pediatric hospital in South Vietnam in 2009–2010. The data were prospectively extracted from the central hospital registry and included basic patient characteristics and diagnoses (International Classification of Diseases, 10th revision. Prematurity, asphyxia and designated congenital malformations (oesophageal atresia, gastroschisis, omphalocoele, diaphragmatic hernia and heart disease were investigated. In a subgroup, the prematurity diagnosis was validated using a questionnaire. The hospitalization ratio of each diagnosis was compared to those obtained from a Danish tertiary hospital. The Danish data were retrieved from the neonatal department database for a ten-year period. Results The study included 5763 neonates (missing Conclusion Our findings suggest the investigated diagnoses were underrepresented in the Vietnamese study hospital. In contrast, relatively mild diagnoses were frequent. These results indicate the use of specialized care may not be optimal. Pre-hospital selection mechanisms were not investigated and additional studies are needed to optimise utilisation of specialized care and improve neonatal survival.

This is the first report in their class.Methods: The data used in this study are derived from the National Register of Hospital Admission/Discharges of the Instituto Nacional de Estadísticas y Censos; data of the Ministry of Public Health were also used. Ecuador does not have an official Medical Birth Registry or a Congenital Malformations Registry.Results: A total of 51,375 discharges by congenital malformations were registered in a 7-year period. Of these, 16,679 admissions were of children aged less than 1 year of age, with a birth prevalence rate (BPR of 72.33/10,000 births. 77% of the congenital defects registered comprise the 50 most common birth defects observed in this age group. Cleft lip was the most prevalent birth defect in children less than 1 year of age and the second most common defect in children 1 to 5 years of age. Unilateral cleft lip shows a BPR of 4.57/10,000 births; cardiac birth defects as a group have a BPR of 4.2; hydrocephalus a BPR of 3.77; and Down’s syndrome a BPR of 3.70. Undescended testicle was the most prevalent birth defect in children between 1 to 5 years. 9384 children under 1 year of age were male (55.9% and 7053 were female (42.1%. BPR in males was 40.45 and in females 30.40.Conclusion: This report documents the prevalence estimates for birth defects reported in the hospital discharge data. These estimates are important to 1 plan for health-care and education needs of the Ecuadorian population, 2 identify increased occurrences of birth defects in specific geographic regions, 3 serve as a reference point for assessment of provincial surveillance systems, 4 evaluate national public health interventions, 5 compare Ecuador prevalence estimates with those of other countries, and 6 help determine the appropriate allocation of resources for basic and public health research. There is an urgent need to establish a National Registry of Birth Defects involving different sources of information such as prenatal medical records, birth records and medical records during the first year of life at an early stage, and surveys on cytogenetic prenatal diagnostic surveys and cytogenetics of therapeutic abortions.Keywords: Ecuador, genetics, birth defects surveillance, database, prevalence, epidemiology, congenital malformations

    Serologic evidence indicated that an episode of congenital abnormalities in sheep was caused by Cache Valley virus (CVV), a bunyavirus indigenous to the United States. To determine the teratogenic potential of CVV in sheep, fetuses were infected in utero between 27 and 54 days of gestation with an isolate (CK-102) obtained in 1987 from a sentinel sheep in San Angelo, Texas. The dams of these fetuses were euthanatized between 28 and 75 days after inoculation, and the fetuses were examined for malformations. Twenty-eight of 34 fetuses had congenital abnormalities, including arthrogryposis, hydranencephaly, mummification, reabsorption, and oligohydroamnion. Virus was isolated from the allantoic fluid of 11 of 17 fetuses euthanatized at less than 70 days of gestation. The virus-positive fetuses, which were all negative for CVV-neutralizing antibody, had lesions ranging from none to severe arthrogryposis and hydranencephaly. Virus was not recovered from the allantoic fluid of fetuses after 76 days' gestation when CVV-specific antibody could be detected in 5 of 8 fetuses examined. The 2 fetuses infected on days 50 and 54 of gestation appeared normal and 1 had antibody to CVV. PMID:2122779

    Pediatric developmental and genetic renal lesions are a known cause of mortality in the perinatal/neonatal period. These lesions are associated with a wide range of extrarenal congenital malformations that influence the outcome of the patients. In this autopsy study, we have analyzed the spectrum of pediatric developmental and genetic renal lesions and their associated congenital malformations. A total of 4,099 autopsies (20 weeks of gestation to 1 year of life) were reviewed, of which 158 cases (3.85%) of pediatric developmental (143 cases) and genetic renal lesions (15 cases) were found. Autosomal recessive polycystic kidney disease was the commonest genetic lesion. Primitive ducts with cuffing of immature mesenchyme--the sine qua non of renal dysplasia--was found in all cases of dysplasia. Associated congenital malformations were seen in all cases and thus a thorough search for them is mandatory. Ductal plate malformation was found in all cases of autosomal recessive polycystic kidney disease and in 1 case of bilateral multicystic dysplasia. PMID:16754487

    Full Text Available Los defectos del desarrollo se pueden deber a malformaciones congnitas, deformaciones o disrupciones. El 10% de las malformaciones se atribuyen a causas ambientales el 25% a factores genticos y el 65% a factores desconocidos probablemente de orden multifactorial. Existe un perodo de mayor susceptibilidad frente a los teratgenos que corresponde a la etapa donde se estn formando la mayora de los rganos y sistemas. La ingestin de plantas teratognicas puede dar lugar a anomalas congnitas en los fetos de animales. Los pesticidas como DDT, la contaminacin de las aguas por mercurio y los disruptores endocrinos afectan la embriognesis de las distintas especies del reino animal. Tambin se consideran como factores causantes de malformaciones a los agentes ambientales infecciosos y a algunos medicamentos. Los agentes fsicos como los aumentos de temperatura, las condiciones de hipoxia y las radiaciones afectan a distintos organismos, desde los peces al ser humano. La gentica de las malformaciones ha sido difcil de establecer, principalmente porque la mayor parte de ellas se caracteriza por presentar manifestaciones fenotpicas diversas, que en muchos casos aparentemente no estn relacionadas y que son variables para los individuos afectados. Por otra parte, los estudios realizados indican que frecuentemente, en la determinacin gentica de las malformaciones participan varios genes y las interacciones de stos con el ambiente, aunque determinaciones monognicas se han podido establecer para unos pocos casos. Ilustramos aqu estos dos tipos contrastantes de determinacin gentica, a travs de la descripcin de los factores genticos que estaran involucrados en los defectos del tubo neural y en el sndrome de CHARGE, respectivamente.Developmental defects may be due to congenital malformations, deformations or disruptions; 10% of malformations are caused by environmental factors, 25% by genetics factors and 65% are due to unknown multifactorial problems. There is a developmental period of greater susceptibility to teratogens, which corresponds to the stages when most organs and systems are being formed. Ingestions of teratogenics plants may result in congenital anomalies in animal foetuses. Pesticide such as DDT, water contamination with the Hg and the endocrine disrupters affect embryogenesis of different animal species. As factors that provoke malformations there are environmental agents, infections and some drugs. Physical agents such as increased temperature, hypoxic conditions and radiation, affect different organisms from fishes to human. Genetic of malformations have been difficult to establish, mainly because most of them are characterized by diverse phenotypic aspects, apparently not related and variable for the different affected organisms. On the other hand, studies realized indicate that frequently in the genetic determination of malformations several genes and their interactions with the environment are involved, although it has been possible to establish monogenic determination for a few cases. Here we contrast these two types of genetic determination, describing the genetic factors involved in the neural tube defects and the CHARGE syndrome, respectively.

  7. Combination of congenital malformations of the kidneys and efferent urinary tract and malformations of the cardiovascular system

    International Nuclear Information System (INIS)

    Compared with malformations of other organ systems, the heart and the large blood vessels as well as the kidneys with the efferent urinary tract are among the organs that most frequently show malformations. For an early diagnosis, excretory urograms are being taken at the authors' institute since 3 years ago. Urography is done subsequently to catheter examinations of the heat, 7 to 10 minutes after injection of a contrasting agent, and the pictures have a format of 70mm. In general the nephograms are easy to use and show malformations of the kidneys and the upper efferent urinary tract. (orig./AJ)

    The use of prenatal ultrasonography has improve the detection of fetal abnormalities, which affects the perception about the natural history and evolution of them, changing the management of the fetus and neonate. Today, it is possible to perform an early prenatal diagnosis, and be treated even intrauterine with high rates of success. Such is the case of Congenital Cystic Adenomatoid Malformation (CCAM), characterized by abnormal proliferation and dilatation of the terminal structures of the airway, generating multiple cysts of diferent sizes and locations. The CCAM can be asymptomatic until adulthood, but sometimes it is presented as an adverse perinatal outcome, manifested with ascites, hydrothorax, hydrops and hypoplasia of the affected lung. We report a case of a pregnant women, 32-year-old, diagnosed on the 18 week pregnancy by ultrasound Type 3 Congenital Cystic Adenomatoid Malformation disease. Treated with an intrauterine intervention percutaneous fetal sclerotherapy successfully. PMID:26233979

  9. A prospective study of congenital malformations among live born neonates at a University Hospital in Western Saudi Arabia

    International Nuclear Information System (INIS)

    Objective was to estimate the incidence of major and minor congenital malformations among live born infants at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Estimation of risk factors was also evaluated. Between March 2004 and May 2005, a total of 5356 babies born at King Abdulaziz University Hospital, were enrolled in this study for malformations. Details of cases were recorded after parent's interviews, clinical, radiological and laboratory evaluations. One hundred and forty-seven (27.06/1000 livebirth) and 13 (2.39/1000 birth) stillbirth have congenital anomalies. In all livebirth, incidences of major anomalies were 93.9% and minor were 6.1%. Mothers of 95.9% with congenital malformation were healthy, 3.4% were diabetic and 0.7% had cardiac malformation. In 38.8% of cases parents were consanguineous. Among the liveborn births, the most common system involved was cardiovascular (7.1/1000), followed by musculoskeletal/limb (4.1/1000), external genitilia (2.8/1000), urinary (2.6/1000),multiple chromosomal (2.2/1000), orofacial (1.9/1000), central nervous system (1.9/1000), skin (1.7/1000), multiple single gene (1.3/1000), multiple sequence (0.75/1000), eyes (0.56/1000), unclassified (0.19/1000), musculoskeletal/abdominal (0.19/1000), endocrine (0.19/1000). High incidence of major malformation was found in Jeddah. Importance of Genetic Counseling is revealed in our study since more than three quarters of mothers were under 36 years and may well plan future pregnancies. (author)

    Purpose: Antenatal diagnosis of congenital cystic adenomatoid lung malformation (CCAM) is vital for disease surveillance and postnatal care. Ultrasonography (US) has been the imaging gold standard for antenatal CCAM assessment. However, one of the limitations of US is the vanishing phenomenon caused by isoechogenicity of CCAM tissue and adjacent normal lung parenchyma. Methods: Antenatal serial US were concurrently used with magnetic resonance imaging (MRI) to monitor macro- and microcystic...

    Major depressive disorder is common among women in child-bearing age, and medical treatment is subject to substantial discussions and controversies. For Selective Serotonin reuptake inhibitors, SSRIs, a vast amount of data are available. For the newer antidepressant group of serotonin and noradrenaline reuptake inhibitors, SNRIs, significantly less data are available. Following the PRISMA guideline for systematic reviews, we performed a systematic search on the risk of major congenital malformations after first trimester in utero exposure to venlafaxine or duloxetine. We identified eight cohort studies reporting on the outcome upon in utero exposure to venlafaxine or duloxetine during the first trimester. The cumulated data for venlafaxine were 3186 exposed infants and 107 major malformations, resulting in a relative risk estimate and 95% confidence interval of 1.12 (0.92-1.35). The corresponding data for duloxetine were 668 infants and 16 major malformations, resulting in a relative risk estimate and 95% confidence interval of 0.80 (0.46-1.29). First-trimester in utero exposure to venlafaxine is not associated with an increased risk of major congenital malformations. The amount of data for duloxetine are significantly smaller but does not suggest a clinically important increased risk. PMID:26435496

    Congenital cardiovascular malformation (CVM) exhibits familial predisposition, but most of the specific genetic factors involved are unknown. Postulating that rare variants in genes in critical cardiac developmental pathways predispose to CVM, we systematically surveyed three genes of the bone morphogenetic protein (BMP) signaling pathway for novel variants. Exonic, splice site, and untranslated regions of BMPR1A, BMPR2, and SMAD6 genes were sequenced in 90 unrelated sporadic cases of CVM. One nonsynonymous variant (p.C484F) with predicted functional impact was found in the MAD homology 2 domain of SMAD6, an intracellular inhibitor of BMP signaling. Sequencing this domain in an additional 346 cases of CVM yielded two further nonsynonymous variants (p.P415L and p.A325T). Functional effects of all three SMAD6 mutations were investigated using BMP signaling assays in vitro. Two SMAD6 variants (p.C484F and p.P415L) had significantly (P < 0.05) lower activity than wild-type SMAD6 in inhibiting BMP signaling in a transcriptional reporter assay. In addition, the p.C484F variant had a significantly (P < 0.05) lower capacity to inhibit an osteogenic response to BMP signaling. We conclude that low-frequency deleterious variants in SMAD6 predispose to CVM. This is the first report of a human disease phenotype related to genetic variation in SMAD6. PMID:22275001

    The objective of the present study was to estimate the advantages of cochlear Baha BIA 400 abutments in the intraoperative and early postoperative periods. A total of 10 implantations of the systems with the use of hydroxyapatite bone cement were performed in 9 patients of different age. Stability of the implants and intensity of skin reactions were evaluated. The data obtained indicate that the use of cochlear Baha BIA 400 abutments significantly simplifies and shortens the surgical stage of rehabilitation producing a good cosmetic result. The use of the Osstell instrument made it possible to estimate stability of the implants intraoperatively and evaluate the effectiveness of osteointegration during the follow-up period. Analysis of the results of the study provided a basis on which to improve the quality and shorten duration of the rehabilitative treatment of the patients presenting with congenital external and middle ear malformations. Moreover, the data obtained can be used to develop practical recommendations for the further work in this area. PMID:24781169

    Full Text Available Background and Aim: Magnetic resonance urography (MRU is considered to be the next step in uroradiology. This technique combines superb anatomical images and functional information in a single test. In this article, we aim to present the topic of MRU in children and how it has been implemented in Northern Greece so far. The purpose of this study is to demonstrate the potential of MRU in clinical practice. We focus both on the anatomical and the quantitative information this technique can offer. Materials and Methods: MRU was applied in 25 children (ages from 3 to 11 years diagnosed with different types of congenital malformations. T1 and T2 images were obtained for all patients. Dynamic, contrast-enhanced data were processed and signal intensity versus time curves were created for all patients from regions of interest (ROIs selected around the kidneys in order to yield quantitative information regarding the kidneys function. Results: From the slopes of these curves we were able to evaluate which kidneys were functional and from the corticomedullary cross-over point to determine whether the renal system was obstructed or not. Conclusion: In all 25 cases MRU was sufficient, if not superior to other imaging modalities, to establish a complete diagnosis.

  19. A prospective study on congenital malformations in the high background radiation areas of Kerala

    International Nuclear Information System (INIS)

    Hospital based epidemiological study on congenital anomalies carried out in the high level natural radiation (HLNR) areas of southern Kerala since 1995 to assess the hereditary effects, if any, of HLNR is reported here. Thorium, Uranium to a limited extent, and corresponding decay products in the natural deposits of monazite sand is the source of radiation. HLNR and normal level natural radiation (NLNR) areas are interwoven due to the patchy and non-uniform distribution of monazite in the region. Areas with a mean dose of more than 1.5 mGy/year were treated as HLNR areas and those with 1.5 mGy/year or less, as NLNR. High population density, limited migration, ethnic diversity, good literacy, health awareness, institutionalized births and acceptance of small family norm are some of the key features of the population. The comparison of individual malformation in HLNR and NLNR areas are presented and efforts are on to accrue sufficient sample size to enable the comparison

  20. Prevalence of congenital malformations in the vicinity of nuclear plants: data from the Central-East France registry

    International Nuclear Information System (INIS)

    To study the prevalence of malformations around the nuclear power plants in the Rhone-Alps region and compare it with their distribution in other parts of the region monitored by the registry. Methods: Municipalities with fewer than 50,000 inhabitants surrounding the 5 nuclear plants in operation from 1979 through 2002 were studied. Every municipality situated near a nuclear site (n=121) was assigned an exposure index, which we estimated from the distance between the municipality and the plant. A Poisson model and a reference population, defined as the 2154 municipalities in the region situated farther than 10 km from a nuclear plant were used to calculate relative risks for congenital malformations, after adjustment for year of birth, maternal age, district of birth, population density, average family income, and presence of chemical plants subject to E U Seveso regulations. Results: Significant differences were not observed for either gene/chromosome anomalies (p=0.50) or minor malformations (p=0.14). Risks for overall malformations and those defined as major non-syndromic appear to be reduced in areas less than 5 km from nuclear plants (RR=0.75 and RR=0.71, respectively). The only comparison showing a higher rate of malformations in populations living near nuclear sites involved rural communities situated 5 to 10 km from a plant (RR=1.41 for the major non-syndromic malformations and 1.31 for all malformations). Conclusion: These results may be random or may be explained by exposure to the plants, but a more likely explanation is the existence of confounding factors for which we could not adjust, such as road traffic for urban communities and pesticides in rural ones.

    Objectives The purpose of the study was to assess the effects of maternal HIV-1 (human immunodeficiency virus) infection and vertically transmitted HIV-1 infection on the prevalence of congenital cardiovascular malformations in children. Background In the United States, an estimated 7000 children are born to HIV-infected women annually. Previous limited reports have suggested an increase in the prevalence of congenital cardiovascular malformations in vertically transmitted HIV-infected children. Methods In a prospective longitudinal multicenter study, diagnostic echocardiograms were performed at 4–6-month intervals on two cohorts of children exposed to maternal HIV-1 infection: 1) a Neonatal Cohort of 90 HIV-infected, 449 HIV-uninfected and 19 HIV-indeterminate children; and 2) an Older HIV-Infected Cohort of 201 children with vertically transmitted HIV-1 infection recruited after 28 days of age. Results In the Neonatal Cohort, 36 lesions were seen in 36 patients, yielding an overall congenital cardiovascular malformation prevalence of 6.5% (36/558), with a 8.9% (8/90) prevalence in HIV-infected children and a 5.6% (25/449) prevalence in HIV-uninfected children. Two children (2/558, 0.4%) had cyanotic lesions. In the Older HIV-Infected Cohort, there was a congenital cardiovascular malformation prevalence of 7.5% (15/201). The distribution of lesions did not differ significantly between the groups. Conclusions There was no statistically significant difference in congenital cardiovascular malformation prevalence in HIV-infected versus HIV-uninfected children born to HIV-infected women. With the use of early screening echocardiography, rates of congenital cardiovascular malformations in both the HIV-infected and HIV-uninfected children were five- to ten-fold higher than rates reported in population-based epidemiologic studies but not higher than in normal populations similarly screened. Potentially important subclinical congenital cardiovascular malformations were detected. PMID:9822105

    We detected an unusual increase in congenital cerebral malformations and dysfunction in fetuses and newborns in French Polynesia, following an epidemic of Zika virus (ZIKV), from October 2013 to March 2014. A retrospective review identified 19 cases, including eight with major brain lesions and severe microcephaly, six with severe cerebral lesions without microcephaly and five with brainstem dysfunction without visible malformations. Imaging revealed profound neurological lesions (septal and callosal disruption, ventriculomegaly, abnormal neuronal migration, cerebellar hypoplasia, occipital pseudocysts, brain calcifications). Amniotic fluid was drawn from seven cases at gestation weeks 20 to 29. ZIKV RNA was detected by RT-PCR and infectious ZIKV isolates were obtained in four of five microcephalic, but not in two non-microcephalic cases with severe brain lesions. Medical termination of pregnancy was performed in eleven cases; two cases with brainstem dysfunction died in the first months of life; six cases are alive, with severe neurological impairment. The results show that four of seven tested fetuses with major neurological injuries were infected with ZIKV in utero. For other non-microcephalic, congenital abnormalities we were not able to prove or exclude ZIKV infection retrospectively. The unusual occurrence of brain malformations or dysfunction without microcephaly following a ZIKV outbreak needs further studies. PMID:27063794

  4. Congenital malformations, stillbirths, and early mortality among the children of atomic bomb survivors: A reanalysis

    International Nuclear Information System (INIS)

    Of all the data sets pertinent to the estimation of the genetic risks to humans following exposure to ionizing radiation, potentially the most informative is that composed of the cohort of children born to atomic bomb survivors. We present here an analysis of the relationship between parental exposure history and untoward pregnancy outcomes within this cohort, using to the fullest extent possible the recently revised estimates of the doses received by their parents, the so-called DS86 doses. Available for study are 70,073 terminations, but DS86 doses have not been or presently cannot be computed on the parents of 14,770. The frequency of untoward pregnancy outcomes, defined as a pregnancy terminating in a child with a major congenital malformation, and/or stillborn, and/or dying in the first 14 days of life, increases with combined (summed) parental dose, albeit not significantly so. Under a standard linear model, when the sample of observations is restricted to those children whose parents have been assigned the newly established DS86 doses (n = 55,303), ignoring concomitant sources of variation and assuming a neutron RBE of 20, the estimated increase per sievert in the predicted frequency of untoward outcomes is 0.00354 (+/- 0.00343). After adjustment for concomitant sources of variation, the estimated increase per sievert in the proportion of such births is 0.00422 (+/- 0.00342) if the neutron RBE is assumed to be 20. A one-hit model with appropriate adjustments for extraneous sources of variation results in an almost identical value, namely, 0.00412 (+/- 0.00364)

  5. The imaging manifestation of congenital cystic adenomatoid malformation of the lung in children

    International Nuclear Information System (INIS)

    Objective: To describe the imaging manifestation in 8 cases of congenital cystic adenomatoid malformation of the lung in children (CCAM) in order to improve the recognition. Methods: Seven males and 1 female were reported, and the mean age was 3 years 10 months. The complaints were cough, fever, and chest distress repeated for 4 days to 8 years. Chest films and CT scan were performed in all cases before operation and three of them were examined by high-resolution CT. All cases were confirmed by operation and pathology as CCAM. Results: (1) On chest films, 4 cases showed single or multiple large air cystic lesions (> 3 cm in diameter), one case only showed localized hazy and curl-like markings, and 3 cases showed honeycomb-like small cystic lesions (< 3 cm in diameter). All cases were complicated with emphysema on affected side. 6 cases showed pulmonary hernia of mediastinum. (2) On CT scan, each lung were involved in 4 cases, 2 cases showed large air cyst (almost 9 cm in diameter), 2 cases showed roundness thin-wall air cystic lesions (3.8-5.6 cm in diameter), and 4 cases showed multiple irregular small air cystic lesions (0.2-3.2 cm in diameter) and adenoid change. The cysts were filled with air but with small amount of liquid in only 3 cases. All lesions showed obvious space occupying sign. (3) The pathologic findings, the cyst was paraplasmic glandular or bronchiolar structures, cyst wall was lined with ciliated pseudo-stratified columnar epithelium in 3 cases and lined by cuboids to columnar epithelium in 5 cases. The cyst wall contained smooth muscle and elastic tissue. Cartilage plates were not present in all cases. Conclusion: Imaging examination is a reliable method in diagnosing CCAM. It can provide the diagnosis in location and quality. CT scan can improve the detection rate of CCAM

  6. The MRI study of the sphincter muscle complex in congenital anorectal malformations

    International Nuclear Information System (INIS)

    Objective: To evaluate the development of the sphincter muscle complex (SMC) and defecation function in pediatric patients with congenital anorectal malformations (ARM). Methods: A total of 64 children underwent MRI, among whom 39 were patients with ARM, and the others were patients without ARM undergoing MRI because of other dieases. The dimensions of the SMC in different planes were evaluated with different sequences and coils. The relationship between the SMC development and the defecation function was investigated. Results: In control group, the absolute value of SMC width was (3.63 ± 0.22)mm, which had a high correlation with age (r=0.998, P0.05). The SMCs in intermediate ARM patients [muscle index (MI)=0.47 ± 0.05] and low ARM patients (MI=0.49 ± 0.05) were well developed. The SMCs in a portion of patients with high ARM (MI=0.28 ± 0.06) were poorly developed, when MI≤0.18, anorectal contraction pressure was significantly lower (t=3.55, P0.18[(0.85 ± 0.20) vs (2.24 ± 1.02) kPa]. The length of anal canal with high-pressure[(10.88 ± 3.64) vs (20.26 ± 4.34)mm] was shorter (t= 5.18, P0.18, the anorectal angle was less than 90 degrees, and normal continent function was found in 21 of 23 cases (91%). Conclusion: MRI can be employed to evaluate the development of SMC in patients with ARM, MI was an objective criteria to evaluate the development of SMC. When MI≤0.18, maldevelopment of SMC will be highly suspected. (authors)

    Full Text Available Abstract Introduction X-linked adrenoleukodystrophy leads to demyelination of the nervous system, adrenal insufficiency, and accumulation of long-chain fatty acids. Most young patients with X-linked adrenoleukodystrophy develop seizures and progressive neurologic deficits, and die within the first two decades of life. Congenital or acquired disorders of the respiratory system have not been previously described in patients with X-linked adrenoleukodystrophy. Case presentation A 3-year-old Arabic boy from Yemen presented with discoloration of the mucous membranes and nail beds, which were considered cyanoses due to methemoglobinemia. He also had shortness of breath, fatigue, emesis and dehydration episodes for which he was admitted to our hospital. Chest radiograph and chest computed tomography scans showed congenital pulmonary adenomatoid malformation. A few weeks before the removal of the malformation, he had a significant episode of hypotension and hypoglycemia. This development required further in-hospital evaluation that led to the diagnosis of adrenal insufficiency and the initiation of treatment with corticosteroids. One year later, he developed seizures and loss of consciousness. Magnetic resonance imaging of his head showed diffuse demyelination secondary to X-linked adrenoleukodystrophy. He was treated with anti-seizure and anti-oxidants, and was referred for bone marrow transplant evaluation. Conclusion The presence of adrenal insufficiency, neurologic deficits and seizures are common manifestations of X-linked adrenoleukodystrophy. The association of congenital lung disease with X-linked adrenoleukodystrophy or Addison's disease has not been described previously.

Positive predictive values were established comparing NPR information with the clinical record of each individual.Results: A total of 2952 patients with a total of 3536 diagnoses were eligible for validation. Review of their clinical records unveiled no patient without cardiac malformation. In 98% (98%–99% of the cases, the NPR diagnosis could be found as the discharge diagnosis in the patient's clinical record, and in 90% (89%–91% of the cases the NPR diagnosis was considered a true reflection of the patient's actual malformation.Conclusions: Our study verifies that the present study population retrieved from the NPR is a valid tool for epidemiological research within the topic of congenital cardiac malformations, given that the research question is not dependent on a fully established sensitivity of the NPR. Precautions should be made regarding cardiac malformations characterized by low prevalence or poor predictive values, and the reported validity should not be extrapolated beyond the study period.Keywords: congenital cardiac malformation, registry, validation

    Full Text Available : INTRODUCTION: Bicornuate uterus is a congenital malformation caused by dysgenesis and fusion defects having two uteri and one cervix [bicornis, unicollis]. METHOD: Among 446 hysterectomy specimens received between April 2010 to April 2013, there were four specimen of bicornuate uterus. OBSERVATION: In this study, along with bicornuate uterus, we observed other associated pathological conditions as follows, 1 Fibroids and adenomyosis, 2 Tubercular endometritis and bilateral tubercular salpingitis. 3 Non-communicating rudimentary horn with hematometra and 4 Endometriosis. CONCLUSION: As there is lot of debate on the symptomatology, in malformed uteri, associated other pathological conditions have to be kept in mind, which are treatable and can reduce the incidence of infertility and other complications.

    Full Text Available Objectives: To investigate the association between per capita pesticide consumption and infant mortality rates from CNS and CVS congenital malformations in microregions in the South and Southeast Region of Brazil. Material and Methods: An ecological study was conducted using data on pesticide expenditure in 1985 and 1996, and deaths caused by CNS and CVS malformations in infants under 1 year old in 1986-1990 and 1997-2001, respectively. Per capita pesticide consumption and infant mortality rates were calculated for each microregion. Microregions were grouped according to quintiles of pesticide consumption, taking the first quintile as reference. The association between pesticide consumption and infant mortality was examined by calculating Spearman correlation coefficients (r and mortality rate ratios (RR, stratifying by gender and type of microregion (urban or rural. Results: Significant and positive correlations between per capita pesticide consumption and rates of mortality due to CNS and CVS defects were observed in rural but not urban microregions. In general, mortality RRs for the 2 types of malformations in rural microregions were significantly higher in each quintile of pesticide consumption compared to the lowest quintile in the 2 study periods, with elevations ranging between 10% and 30%. Likewise, mortality RRs in these microregions showed significant trends of increase across quintiles of pesticide consumption in both study periods. In urban areas, however, mortality RRs from both CNS and CVS malformations were weak and not statistically significant, and a trend of increase of mortality with increasing pesticide usage was not observed. Conclusions: The results show the relevance of pesticide exposure in rural areas with intense agricultural activity, suggesting that such prenatal exposures may be related with the occurrence of certain congenital defects.

    Using exome sequencing we identify a heterozygous nonsense mutation in ZFPM2 as a cause of familial isolated congenital diaphragmatic hernia in 2 affected siblings. This mutation displays variable phenotypic expression being present in a third sibling with a mild diaphragmatic eventration and a cardiovascular malformation. The same variant is seen in 2 additional family members, both of whom are asymptomatic, thus highlighting that ZFPM2 haploinsufficiency is associated with reduced penetrance. Our finding adds further evidence for ZFPM2 having a role in diaphragm and cardiovascular development. PMID:24769157

    This study explores the inorganic composition of amniotic fluid in healthy human fetuses and fetuses with congenital malformation with a special attention to presence of metal-based solid particles. Amniotic fluid originates from maternal blood and provides fetus mechanical protection and nutrients. In spite of this crucial role, the environmental impact on the composition of amniotic fluid remains poorly studied. The samples of human amniotic fluids were obtained by amniocentesis, including both healthy pregnancies and those with congenital malformations. The samples were analysed using several techniques, including Raman microspectroscopy, scanning electron microscopy with energy-dispersed spectrometry (SEM-EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis. Several metal-based particles containing barium, titanium, iron, and other elements were detected by SEM-EDS and Raman microspectroscopy. XRD analysis detected only sodium chloride as the main component of all amniotic fluid samples. Infrared spectroscopy detected protein-like organic components. Majority of particles were in form of agglomerates up to tens of micrometres in size, consisting of mainly submicron particles. By statistical analysis (multiple correspondence analysis), it was observed that groups of healthy and diagnosed fetuses form two separate groups and therefore, qualitative differences in chemical composition may have distinct biological impact. Overall, our results suggest that metal-based nanosized pollutants penetrate into the amniotic fluid and may affect human fetuses. PMID:25561252

  17. Congenital malformations of the supratentorial brain. Pt. 1. Disorders of cortical development

    International Nuclear Information System (INIS)

    Disorders of supratentorial cortical development are usually divided into disorders of neuronal proliferation, neuronal migration and cortical organization. Based upon molecular biologic discoveries, a modified classification has recently been proposed. The category of malformations of abnormal neuronal and glial proliferation and apoptosis now includes microlissencephalies, megalencephalies, hemimegalencephalies and cortical dysplasias with balloon cells. Malformations due to abnormal neuronal migration now subsume the lissencephaly spectrum including the subcortical band heterotopias, the cobblestone complex and the group of heterotopias. Malformations due to abnormal cortical organization include the spectrum of polymicrogyria and schizencephaly as well as cortical dysplasias without balloon cells. High-resolution magnetic resonance imaging (MRI) has led to an increasing awareness of these malformations. This article aims to illustrate the classification, MRI presentation and relevant clinical features of the most commonly encountered disorders of cortical development. (orig.)

    Full Text Available OBJECTIVE: To identify the left inferior pulmonary vein as an indirect marker of increased pulmonary flow in congenital heart diseases.METHODS: We carried out a prospective consecutive study on 40 patients divided into 2 groups as follows: G1 - 20 patients diagnosed with congenital heart disease and increased pulmonary flow; G2 (control group - 20 patients who were either healthy or had congenital heart disease with decreased or normal pulmonary flow. We obtained the velocity-time integral of the left inferior pulmonary vein flow, excluding the "reverse A" wave, with pulsed Doppler echocardiography.RESULTS: In G1, 19 out of the 20 patients had well-identified dilation of the left inferior pulmonary vein. No G2 patient had dilation of the left inferior pulmonary vein. Dilation of the left inferior pulmonary vein in conditions of increased pulmonary flow had sensitivity of 95%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 95% (1 false-negative case. The integral of time and velocity of the pulmonary venous flow obtained with pulsed Doppler echocardiography was greater in the G1 patients (G1=25.04.6 cm versus G2=14.82.1 cm, p=0.0001.CONCLUSION: The identification of dilation of the left inferior pulmonary vein suggests the presence of congenital heart disease with increased pulmonary flow. This may be used as an indirect sign of increased flow, mainly in malformations of difficult diagnosis, such as atrial septal defects of the venous sinus or coronary sinus type.

  2. MRI of the lumbar spine at 7 Tesla in healthy volunteers and a patient with congenital malformations

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate sequences that are established at lower magnetic field strengths for lumbar spine imaging at 7 Tesla (7 T) MR imaging. The lumbar spine of five healthy volunteers and a patient with spina bifida and meningocele were evaluated at 7 T. The examination included a T2-TSE (turbo spin echo), a 3D-DESS (double-echo steady-state sequence), a 3D-CISS (constructive interference in steady-state sequence), and a 3D-VIBE (volumetric interpolated breath hold examination) sequence. Imaging quality was evaluated by two raters on a three-level scale. The assessment included visualization of intraforaminal structures, the cauda equina, facet joints, and any abnormalities. Contrast ratios for intervertebral discs/vertebral bodies, vertebral bodies/cerebrospinal fluid (CSF) and CSF/spinal cord were calculated. The 3D-VIBE sequence provided best differentiation between intraforaminal structures. Visualization of the facet joints was reliable with VIBE, DESS, and CISS. Individual nerve roots of the cauda equina could only be delineated with the 3D-CISS sequence. CISS and DESS provided good contrast between vertebral bodies and intervertebral discs. Contrast between CSF and vertebral bodies was most pronounced for the T2-TSE sequence. Sufficient contrast between CSF and the spinal cord was only achieved with the T2-TSE sequence. VIBE and DESS sequences demonstrated best the bony malformations. Visualization of the meningocele was only possible with the 3D-CISS sequence. At 7 T most structures of the lumbar spine were visualized with a combination of sequences. At present, imaging quality is not superior to 1.5 T or 3 T, precluding routine clinical use. (orig.)

    Full Text Available Abstract Background Complex vertebral malformation (CVM and bovine leukocyte adhesion deficiency (BLAD are two autosomal recessive lethal genetic defects frequently occurring in Holstein cattle, identifiable by single nucleotide polymorphisms. The objective of this study is to develop a rapid and reliable genotyping assay to screen the active Holstein sires and determine the carrier frequency of CVM and BLAD in Chinese dairy cattle population. Results We developed real-time PCR-based assays for discrimination of wild-type and defective alleles, so that carriers can be detected. Only one step was required after the DNA extraction from the sample and time consumption was about 2 hours. A total of 587 Chinese Holstein bulls were assayed, and fifty-six CVM-carriers and eight BLAD-carriers were identified, corresponding to heterozygote carrier frequencies of 9.54% and 1.36%, respectively. The pedigree analysis showed that most of the carriers could be traced back to the common ancestry, Osborndale Ivanhoe for BLAD and Pennstate Ivanhoe Star for CVM. Conclusions These results demonstrate that real-time PCR is a simple, rapid and reliable assay for BLAD and CVM defective allele detection. The high frequency of the CVM allele suggests that implementing a routine testing system is necessary to gradually eradicate the deleterious gene from the Chinese Holstein population.

  6. Massive hematuria due to a congenital renal arteriovenous malformation mimicking a renal pelvis tumor: a case report

    Directory of Open Access Journals (Sweden)

    Sountoulides P

    2008-05-01

    Full Text Available Abstract Introduction Congenital renal arteriovenous malformations (AVMs are very rare benign lesions. They are more common in women and rarely manifest in elderly people. In some cases they present with massive hematuria. Contemporary treatment consists of transcatheter selective arterial embolization which leads to resolution of the hematuria whilst preserving renal parenchyma. Case presentation A 72-year-old man, who was heavy smoker, presented with massive hematuria and flank pain. CT scan revealed a filling defect caused by a soft tissue mass in the renal pelvis, which initially led to the suspicion of a transitional cell carcinoma (TCC of the upper tract, in view of the patient's age and smoking habits. However a subsequent retrograde study could not depict any filling defect in the renal pelvis. Selective right renal arteriography confirmed the presence of a renal AVM by demonstrating abnormal arterial communication with a vein with early visualization of the venous system. At the same time successful selective transcatheter embolization of the lesion was performed. Conclusion This case highlights the importance of careful diagnostic work-up in the evaluation of upper tract hematuria. In the case presented, a congenital renal AVM proved to be the cause of massive upper tract hematuria and flank pain in spite of the initial evidence indicating the likely diagnosis of a renal pelvis tumor.

    Full Text Available Premature ovarian failure (POF, that is, amenorrhea before 40 years of age can be attributed to a variety of etiologies. Approximately 1% of women before 30 years are diagnosed with POF. Spontaneous ovulation leading to pregnancy in POF is even a rarer entity. We report a case where congenital malformations were diagnosed in a fetus following spontaneous ovulation in a case of POF. A 33-year-old woman presented to our center with primary infertility. On complete work up, she was diagnosed with POF and conceived with hormone replacement therapy and donor oocyte program. She delivered a healthy female baby through caesarean section. The patient reviewed later with amenorrhea of 40 days and pregnancy was confirmed. However, during antenatal follow-up congenital anomalies in fetus were diagnosed sonographically. The decision for termination of pregnancy was taken. To conclude, we recommend large-scale retrospective analysis that would define medical guidelines in cases of pregnancy following spontaneous ovulation in POF.

    Full Text Available The role of advanced maternal age as a risk factor for congenital malformations in offspring is known. However, the influence of paternal age is not clear. Aim: To evaluate the association between advanced paternal age and the risk for congenital malformations. Patients and Methods: Analysis of maternal and paternal age of cases (malformed newborns and controls from ECLAMC Database (Latin American Collaborative Study of Congenital Malformations registered at the University of Chile Clinical Hospital during the decade from Jan 1 1997 to Dec 31 2006. Newborns and stillborns were grouped according to maternal age into 6 intervals. In each interval, paternal ages of cases and controls were compared. The inverse procedure was performed to assess maternal age effect. Other variables as gestational age and birth weight were analyzed for the intervals of maternal and paternal ages. Results: No significant differences were observed in paternal age between cases and controls in any of the intervals of maternal age. However, mean maternal age was higher for cases than for controls (p =0,0149. Gestational age and birth weight depend more on being case or control than on the age of parents. Conclusions: No differences in paternal age were observed between cases and controls in this series of newborns

  9. Radiologic aspects of the congenital arteriovenous malformations, Klippel-Trenaunay type, and Servelle-Martorell type

    International Nuclear Information System (INIS)

    In our study 13 patients with a Klippel-Trenaunay type and 7 patients with a Servelle-Martorell type of arteriovenous malformations were analyzed. The results demonstrate that these 2 entities can be differentiated by routine radiography. The Klippel-Trenaunay type of angiodysplasia does not need arteriography, whereas arteriography as well as phlebography are necessary in the Servelle-Martorell type of angiodysplasia, in order to show ectatic regions of the involved vessels. The differentiation between the above mentioned arteriovenous malformations and the F.P. Weber type of angiodysplasia is easy. In the F.P. Weber type of angiodysplasia a lengthening of the involved extremity, arteriovenous shunts, as well as alterations of the bone are characteristic. (orig.)

Abstract in english Congenital pulmonary airway malformation or CPAM (congenital cystic adenomatoid malformation) that involve the lung is an embryonic anomaly. CPAM is a rare condition in chilhood, and even more so in adulthood. In this article we report the case of a young adult man with CPAM and present a brief revi [...] ew about this condition. Case study: 23 years old man with several episodes of pneumonia and obstructive bronchial syndrome during his childhood. The patient complained of pleuritic chest pain, malaise and fever. On physical examination lung sound was diminished in the lower right zone of the chest, abundant coarse crackles were detected and there was dullness on percussion. Chest roentgenogram and computed tomography (CT) revealed a complex image of multiple cysts with air and fluid in the right lung. Because of the lack of response to medical treatment a right lower lobectomy was performed. Histopathology revealed a type 1 CPAM. After being discharged from the hospital the patient developed a broncho-pleural fistula, that was succesfully treated by a second surgical intervention. Three years after surgery the patient is free of symptoms. Discussion: CPAM is a rare congenital hamartomatous condition. This malformation in adults it is exceptional. Chest CT is the choice diagnostic technique. Considering the high neoplastic potential of this malformation, its treatment should be the surgical resection, even in asymptomatic patients.

    A 4-month-old, 20 kg, intact male, cane corso dog was presented with a slowly growing subcutaneous lesion on the left caudoventral abdominal wall. Ultrasound and computed tomography angiography revealed a subcutaneous plexus of aberrant tortuous vessels directly connected with the superficial branch of the deep circumflex iliac artery and vein. The arteriovenous malformation (AVM) was successfully surgically removed. Early recognition and surgical removal of AVM can have excellent cosmetic results and prevents potential cardiovascular complications. PMID:26175066

    Full Text Available Background: Consanguinity plays an important role in the genetic etiology of congenital malformations. In Easter Island the degree of consanguinity could be higher than in continental Chile. Therefore the study of the prevalence of congenital malformations in this island seems worthwhile. Aim: To study the prevalence of congenital malformations at birth in Easter Island. Material and methods: A review of personal and family features of all children born alive between 1988 and 1998 in the Rapa Nui Hospital of Easter Island. Results: During the study period, 772 newborns were reviewed and 22 were found to have congenital malformations. Among the latter, birth weight fluctuated between 3001 and 4000 g and the male/female ratio was 0.54. No differences in maternal age between children with and without malformations was observed. Heart and circulatory malformations, hemangiomas and Down syndrome were the predominant malformations. Conclusions: The prevalence of congenital malformations at birth in Easter Island is similar to that of continental Chile. No neural tube defects were detected in this sample.

    Aniridia is a congenital and progressive panocular condition with poor visual prognosis that is associated with brain, olfactory, and pancreatic abnormalities. Development of aniridia is linked with nonsense mutations that result in paired box 6 (PAX6) haploinsufficiency. Here, we used a mouse model of aniridia to test the hypothesis that manipulation of Pax6 dosage through a mutation-independent nonsense mutation suppression strategy would limit progressive, postnatal damage in the eye. We f...

Patients and Methods: population-based case-control study through selection of the first six live births on a day, over the period of a year, at a public maternity in Salvador, Bahia, with a total of 800 cases. Studies were performed through investigation of birth records in the search of congenital malformation data, observation of selected malformed newborns, followed by interview with the mothers for collection of anamnesis data, by application of a questionnaire. Later on data were statistically evaluated by Epi-Info 5.0 software. Results: puerperae came from a low socialeconomic class (74.8%, without any or almost any schooling (61.1%. The general percentage of birth defects was estimated at 4.7%. Out of 800 puerperae, 16% reported abortifacient drug intake during the first 3 months of gestation and 10.9% of them had malformed babies. This incidence was 3.6% in children whose mothers denied the intake of any abortifacient drugs. Agents most commonly taken in those unsuccessful abortive attempts were misoprostol (Cytotec and herbs, specially "alum" (Vermonia baiensis Tol and "espinho cheiroso" (Kanthoxilum shifolium Lam, which, according to the literature, do not really have any abortive effect. Conclusion: the study revealed the extension of intentional miscarriage in a low income population and showed that the occurrence of birth defects could be related to gestational exposure to misoprostol and herbal medicine intake.

    The aim of this study was to evaluate the toxicity of Stryphnodendron fissuratum pods in guinea pigs (Cavia porcellus) and test the hypothesis that this plant has teratogenic effects. Thus, sixteen guinea pigs were randomly divided into four groups of four animals each. Groups 10, 20 and 40 consisted of guinea pigs that received commercial food that contained crushed pods of S. fissuratum at concentrations of 10, 20 and 40 g/kg, respectively, during the period of organogenesis. Control group consisted of guinea pigs under the same management conditions that did not receive crushed pods of S. fissuratum in their food. In all experimental groups, the main clinical signs of poisoning consisted of anorexia, prostration, absence of vocalizations, alopecia, diarrhea, and abortions within the adult guinea pigs. Those that did not abort gave birth to weak, malnourished pups, some of which had fetal malformations. The main teratogenic changes consisted of eventration, arthrogryposis, amelia of the forelimbs, anophthalmia, microphthalmia, anotia and agnathia. The reductions in the number of offspring and the malformations observed in the experimental groups suggest that S. fissuratum affects fetal development and is teratogenic. PMID:26363291

    Little information exists on the possible teratogenic effect of modern antiobesity drugs. The present study refers to orlistat, sibutramine, and rimonabant. Data in the Swedish Medical Birth Register were utilised. During the years 1998-2011, among 392,126 infants born, 509 had been exposed to antiobesity drugs in early pregnancy: 248 to orlistat, 242 to sibutramine, 12 to rimonabant, 13 to unspecified antiobesity drugs. Simultaneous use of orlistat and sibutramine occurred in six cases. No increase in major malformation risk was seen after orlistat (relative risk=0.42, 95% confidence interval 0.11-1.07) but a significantly high risk was seen after sibutramine (relative risk=1.81, 95% confidence interval 1.02-2.99). The latter effect, which seemed to be mainly due to an increased risk for a cardiovascular defects, may be related to the capacity of the drug to prolong QT-time. Sibutramine has been withdrawn in Europe but is still available on the Internet and is a component in some slimming preparations. Among the 12 infants exposed to rimonabant, two which were in a twin pair were malformed. PMID:25434912

    International Nuclear Information System (INIS)

    Although congenital varicella-zoster virus VZV infection is rare, it carries serious morbidity and mortality to the fetus and newborn infant. We report a full term female newborn infant, born to a multipara unbooked mother who had VZV subclinical infection during the first trimester of pregnancy. Routine newborn examination showed cystic malformation of the left eye, and absence of the right eye globe. Radiological work up revealed severe brain and eye malformations, serological studies of both mother and baby were positive for VZV. The baby underwent palliative surgery to the eyes, upon discharge, a plan of multidisciplinary team was made for follow up including neurologist, ophthalmologist, pediatrician and social worker. Congenital VZV infection can be severe enough to cause catastrophic fetal anomalies and damage to the vital organs as many of those infants die in infancy. (author)

    Full Text Available Background: Birth defects, encountered frequently by pediatricians, are important causes of childhood morbidity and mortality. Birth defects can be classified based on their severity, pathogenic mechanism or whether they involve a single system or multiple systems. This hospital based prospective descriptive study highlights the prevalence of congenital anomalies (CAs in one year, among liveborn neonates delivered in a university hospital. Design and methods: All women giving birth to babies were included. Demographic details, associated risk factors and the type of CAs in babies were recorded. Diagnosis of CAs was based on clinical evaluation, radiographic examination and chromosomal analysis of newborn whenever recommended. Results: The overall incidence of CAs among liveborn neonates was 2.5%, as most of the cases were referred to Zagazig University Hospital for delivery. The musculoskeletal system (23% was the most commonly involved; followed by central nervous system (20.3%. Involvement of more than one system was observed in (28.6% cases. Out of the maternal and fetal risk factors, parental consanguinity, maternal undernutrition and obesity, positive history of an anomaly in the family, low birth weight(LBW, and prematurity were significantly associated with higher frequency of CAs(p <0.05, with non-significant differences for maternal age and the sex of the neonates. Conclusion : The current study highlighted the point prevalence of congenital anomalies in one year in zagazig university hospital in Egypt. The present study revealed a high prevalence of congenital anomalies in our locality and stressed upon the importance of carrying out a thorough clinical examination of all neonates at birth.

    This paper presents the state of genetic health of the human populations in two Romanian counties, Bacau and Vaslui, as they are different in area, number of inhabitants, level of economic and social development, etc. The data presented in this paper is from the Public Health Directions of the two counties, reflecting the situation recorded during 20062013. In the 8 years study, 1894 cases of congenital and chromosomal disorders were recorded in the newborns from the populations in the two counties. The identified cases were distributed based on years, categories of disorders and sexes. The average frequency of congenital disorders in the two populations over the investigated period was about 1.65 in Bacau county and 1.83% in Vaslui counties. In the population of Bacau county, these disorders affect in the same number in both the sexes (49.62% female cases and 50.38% male cases), while in Vaslui, the male cases are more than the females (53.92 and 46.08%, respectively). The main congenital disorders observed were: cardiovascular system anomalies, musculoskeletal system, urogenital system, etc. During the investigation period, in the human population of Bacau county, 97 cases of newborns with chromosomal disorders were diagnosed (0.16% of the living newborns), while in Vaslui county there were 106 cases (0.26% of the living newborns). Among these disorders, the Downs syndrome was the most frequent one, representing 83.5 and 85.8% of cases in the population of Bacau county, and Vaslui counties.

    The joint toxic action of three binary mixtures was determined for the embryo malformation endpoint of the aquatic FETAX (frog embryo teratogenesis assay: Xenopus) test system. Osteolathyrogenic compounds and short-chain carboxylic acids, representing separate, distinct modes of action for induction of malformation, were selected for testing in 96-hr, static-renewal tests. Three mixtures were tested for each combination, with each combination being tested on three separate occasions. Using toxic unit analysis, the combination of osteolathyrogens and the combination of carboxylic acids produced strictly additive (concentration addition) rates of malformation, while the combination of an osteolathyrogen and a carboxylic acid was less-than-additive (response addition) for induction of malformation. Therefore, developmental malformation may have value as an endpoint in mixture toxicity hazard assessment.

    The previously reported hypothesis of an etiologic association of heart and blood abnormalities was further investigated in a population based study of congenital cardiovascular malformations (CCVM). Three presumed genetic risk factors (CCVM in parents and siblings, heritable blood disorders and maternal mitral valve prolapse) were found to occur significantly more often in cases than in normal controls, irrespective of the presence in the proband of chromosomal or Mendelian lesions. This suggests a specific etiologic origin of the CCVM; the excess of maternal risk components raises the possibility of X-linked inheritance. Observed constellations of heart, blood, and connective tissue disorders within members of a nuclear family may indicate variability of phenotypic expression of a similar biosynthetic defect. A schematic model of abnormal cardiogenesis is presented which supports the above observations with the results of biochemical studies on endothelium, platelets and collagen disorders. It is suggested that teratogenesis results from subtle interactions of genetic sequelae with extrinsic metabolic and xenobiotic effects. This conclusion harmonizes with those derived from experimental animal studies. PMID:2937867

    Full Text Available Abstract Background Spontaneous monochorionic triamniotic pregnancy is rare and is at increased risk for pregnancy complications. The presence of an anomalous fetus further complicates the management. Case presentation We present a case of monochorionic triamniotic triplet pregnancy diagnosed at 15 weeks of gestation with one fetus having developed a multicystic lung lesion, suggestive of congenital cystic adenomatoid malformation (CCAM. At 24 weeks, the largest cyst measured 10 mm in diameter. We managed the pregnancy conservatively and delivered three live male fetuses with birth weights 1560 g, 1580 g and 1590 g at 35 weeks of gestation. Two newborns were admitted to the neonatal intensive care unit with respiratory distress, the third one died due to sepsis 7 days postpartum. One of the newborns was discharged healthy at 24 days postpartum. The newborn with CCAM developed a pneumothorax on the right side, recovered after treatment, and was discharged after one month. Computerized tomography (CT of the infant at 3 months demonstrated two cystic lesions in the middle lobe of the right lung measuring 25 mm and 15 mm. A repeat CT of the infant at 6 months showed a 30 mm solitary cystic mass. Conclusion Monochorionic triamniotic triplet pregnancy with a co-triplet fetus discordant for CCAM, present rarely and can be managed conservatively. These findings may help in decision making and counselling of parents.

  6. The prevalence at birth of congenital malformations in the city of Ozyorsk located near the nuclear complex Mayak production association

    International Nuclear Information System (INIS)

    For many years possible genetic effects of exposure to ionizing radiation have been a subject of interest and concern, but data from studies of the risk of radiation-induced hereditary effects in humans are limited. the most extensive human studies of genetic effects were those conducted on the Japanese. A-bomb survivors. In These studies in investigators examined the association of various levels of radiation exposure and several different endpoints, including major congenital defects, stillbirth, death during the first week of life, survivals, and sex ratio and Down's syndrome (8, (14-16). Although associations of these outcomes with radiation exposure were in the positive direction, none were close to statistical significance. Only teratogenic effects of in utero exposure at Hiroshima and Nagasaki, microcephaly and mental retardation, have been observed (8, (10, 16)). Of most interest is possible association of congenital malformations (CMs) with parental occupational radiation exposure. Determination of the role of parental occupational exposure in induction of CMs in children is necessary to evaluate reliability of radiation protection standards Epidemiological studies conducted on the basis of Registries of children who were born in regions located near a nuclear complex may be useful for such evaluation. It is preferable to carry out such studies on the basis of population registries, since long follow-up in large populations allows to reveal increased frequency of even very rare forms of congenital abnormalities. In a case-control study of association of parental occupational exposure due to Hanford Nuclear Site and risk of CMs in their offspring there was no evidence of such an association (12, 13). Our investigation is conducted on the basis of the basis of the Registry of children of Ozyorsk. The whole Registry includes all children with 1948-1988 birth years show were born or-came to town at the age of 0-14 years, and were residents of these towns one year at least. Ozyorsk is located near the large-scale nuclear complex Mayak which became operational in the Southern Ural in 1948. The aim of our follow-up is to study prevalence of CMs detected at birth or during the first year of life among the children born in the city of Ozyorsk in 1974-1988. This cohort was chosen for study, because medical records on children of this birth years are well preserved and the most complete information for these years might be obtained. (Author) 17 refs

    Full Text Available [...] Abstract in english Background: The Latin American Collaborative Study of Congenital Malformations (ECLAMC) is an epidemiological surveillance system operating in 11 South American countries since 1969. Aim: To analyze the Congenital Malformation prevalence rate at birth from 2001 to 2010 in Chilean Hospitals participa [...] ting in ECLAMC. To compare these rates with those of the period 1982-1994. Material and Methods: Review of the ECLAMC database, which contains information about 282.568 newborns, 2.110 of them stillbirths (0.75%) from 13 Maternity hospitals. Results: In the study period, 10.925 newborns had congenital malformations (3.9 %). Their frequency was lower in live newborns than stillbirths (3.8 and 15.3%, respectively). Compared with the 1982-1994 period, congenital malformation prevalence rates at birth were higher. They stabilized in approximately 4 %, from 1985 to 2010. The prevalence of some anomalies such as Down syndrome increased significantly. On the other hand, there was a reduction in the prevalence of spina bifida and anencephaly. Conclusions: Prevalence rates of congenital malformations at birth remained stable in the last 18 years in Chilean Hospitals participating in ECLAMC. However the prevalence of some malformations such as Down syndrome, Polydactyly, anotia-microtia, syndactyly and cleft palate have increased. The prevalence rates of spina bifida and anencephaly have decreased.

    Full Text Available Se hizo un resumen del trabajo realizado durante 13 aos con ecografa bidimensional en el Departamento de ultrasonido de nuestro hospital, motivados por la importancia de la deteccin intratero, cada vez ms precoz, de las malformaciones congnitas, con el propsito de demostrar el valor de la ecografa bidimensional para el diagnstico de stas. Revisamos los expedientes clnicos de las pacientes con malformaciones diagnosticadas y analizamos variables como: positividad del diagnstico, principales tipos de malformaciones encontradas, as como las causas de los errores cometidos. Entre los principales resultados obtenidos tenemos que de los 73 866 exmenes realizados, encontramos 147 malformaciones, o sea, una malformacin por cada 502,4 estudios realizados, lo que arroja un promedio anual de 11,3 malformaciones. Entre las malformaciones ms frecuentemente diagnosticadas encontramos los del sistema nervioso central, siguindoles las renales, cardacas, digestivas y otras. Concluimos sealando que a pesar de las novedosas tcnicas aparecidas ltimamente, la ecografa bidimensional sigue siendo, en manos expertas, un medio ideal, relativamente barato o inocuo para el diagnstico de las malformaciones congnitas.It was made a summary of the work carried out during 13 years with bidimensional echography at the Ultrasound Department of our hospital, motivated by the importance of detecting intrauterus, increasingly early, and congenital malformations aimed at demonstrating the value of bidemensional echography for their diagnosis. The medical histories of the patients with diagnosed malformations were reviewed and variables such as the positivity of the diagnosis and the main types of malformations found were analyzed. The causes of the mistakes made were also examined. Among the principal results obtained it was found that of the 73 866 examinations made 147 were malformations, that is, a malformation per every 502.4 conducted studies. The annual average was of 11.3 malformations. One of the most frequently diagnosed malformations was that of the central nervous system, followed by the renal, cardiac, digestive and others. It is concluded that in spite of the appearance of new techniques, the bidemensional echography is still, in expert hands, a relatively cheap or innocuous ideal means for the diagnosis of congenital malformations.

  12. Complex congenital heart malformation evaluated with MR imaging at 0.3 T

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the efficiency of MR imaging at 0.3 T as the single modality in diagnosing complex congenital heart disease (CHD). Films from 45 cases were reviewed in two stages by four specialists and one fellow in pediatric radiology, who were unfamiliar with the patients. First a general review of CHD diagnosis was made, then a detailed study of anomalous venous return was performed. Regarding the general diagnosis of cardiovascular anomalies the results were good, with sensitivity of 80%, specificity of 96%, a positive predictive value of 88%, a negative predictive value of 93% and accuracy of 92%. As expected, the less experienced reviewer had somewhat lower figures. As for detailed evaluation of the anomalous veins, the diagnostic results were again good (sensitivity 85%), although less so when also the connection sites of the anomalous veins were considered (sensitivity 79%). The specificity of the findings was high at 97%. MR imaging at 0.3 T is valuable in the diagnosis of comples CHD, especially for anomalous vessels and their connections. (orig.)

  13. Temporal characteristics related to leave from work and pregnancy among mothers with congenitally malformed offspring

    The possible impact of occupational factors on the furtherance of congenital defects have been under study at our department for the past 4 years. The topic has assumed a special interest because of the importance of the issue involved, namely the search for a possibility to prevent teratogenesis, and partly because the applicable methods are different from those of customary epidemiology. In connection with a register-based, case-referent study utilizing supplementary information, acquired via questioning, of conditions at the mothers' work places, we analysed various time-related events in their pregnancy. We found that the groups compared differed from each other with regard to the correct timing of the birth, despite the fact that the distribution of the times of stopping work for various reasons were alike. Among mothers who were granted sick leave from work the diagnosis of anencephaly became less common close to the estimated date of delivery, and conversely for the diagnosis of hydrocephaly. The findings of the present study may suggest that the time of assignment for a statutory maternity leave be considered. Methodological issues in study design are also briefly discussed.

    The paper deals with the possibility of surgical reconstruction of congenital malformations of the ear, the choice of a proper surgical method with the utilization of calf-vein xenografts, and with postoperative effects of the employed operative technique modified by the authors. The research material comprised 70 children between 3 and 17 years of age treated in years 1992-1995. Reconstructive surgery was performed in 24 children (29 ears). Calf-vein xenografts were used for myringoplasty and for the lining of the bony walls of the postoperative cavity (of the created external auditory canal and of the mastoid cavity). Hearing improvement was gained in 79% of cases, and in 55% of patients it was 24 dB or higher. Patent and epithelilized external auditory canals were obtained in 81% of the operated "atretic" ears. Failures referred to fibrodermal restenosis and lack of hearing improvement. Surgical treatment of bilateral congenital aural "atresia" can be performed in children at 4-6 years of age. Vein xenografts are a good reconstructive material recommended in congenital aural malformations for myringoplasty and canaloplasty. PMID:10581956

    Congenital anomalies in horses are very rare, and contracted foal syndrome is one of the most commonly reported. This malformation is characterized by contraction of the joints of the forelimbs and/or hindlimbs. In addition, the syndrome can be characterized by vertebral column malformations, such as scoliosis or torticollis, and cranial deformity. The present report describes the radiological and necroscopical findings of multiple rare malformations in two foals. Both foals showed skeletal abnormalities and fenestration of the abdominal cavity. Other pathological findings include a interventricular septal defect in one and a unilateral hydronephrosis and partial hydroureter in the other foal. Although in this report a specific aetiology could not be provided, insecticides treatment provided during the second month of pregnancy might play a role in the pathogenesis of these malformations.

    Full Text Available Malformações congênitas causadas pela ingestão de Mimosa tenuiflora têm sido observadas em ruminantes no semiárido do Nordeste Brasileiro. Neste trabalho foram estudadas as malformações congênitas em ruminantes diagnosticadas entre 2000 e 2008, em municípios da Paraíba, Pernambuco e Rio Grande do Norte. Durante o período foram recebidos 1.347 materiais de ruminantes para diagnóstico, desses 47 (3,48% foram dignosticados como malformações congênitas. Com base no tipo de malformação e na procedência do animal as malformações foram divididas em: 1 causadas pelo consumo de M. tenuiflora; e 2 malformações esporádicas, sem causa conhecida. De 418 materiais de ovinos, 21 corresponderam a malformações, sendo 18 (4,3% do total de materiais de malformações causadas por M. tenuiflora e 3 (0,71% de malformações esporádicas. De 434 materiais de bovinos, 14 foram diagnosticados como malformações, sendo 8 (1,84% causadas por M. tenuiflora e 6 (1,38% malformações esporádicas. De 495 materiais de caprinos, 12 apresentaram malformações, sendo 9 (1,81% causadas pela ingestão de M. tenuiflora e 3 (0,6% malformações esporádicas. As principais malformações causadas por M. tenuiflora foram artrogripose, micrognatia, palatosquise, microftalmia e hipoplasia ou aplasia unilateral ou bilateral dos ossos incisivos. As malformações esporádicas incluiram: acefalia e hermafroditismo, dicefalia e malformações de vasos intestinais em ovinos; atresia anal em três caprinos; e hidranencefalia, atresia anal, malformações de costelas com eventração, hipoplasia cerebelar e hidrocefalia, coristoma pulmonar e meningocele, e gêmeos siameses em bovinos. O caso de hipoplasia cerebelar com hidrocefalia foi negativo pela imuno-histoquímica para o vírus da diarreia viral bovina. Malformações congênitas causadas por M. tenuiflora ocorreram durante todo o ano. A maior frequência em ovinos está aparentemente associada ao consumo da planta, na primeira fase da gestação, após as primeiras chuvas, quando as ovelhas estão sendo suplementadas e a planta é o principal volumoso disponível. As malformações ocorrem principalmente nas áreas mais degradadas, onde existe maior disponibilidade da planta e menor variedade de plantas da caatinga.Congenital malformations caused by the ingestion of Mimosa tenuiflora have been reported in ruminants in the semiarid of the Brazilian Northeast. This paper reports malformations diagnosed in ruminants, from 2000 to 2008, by the Veterinary Pathology Laboratory of the Federal University of Campina Grande, Patos, PB, in municipalities of the states of Paraíba, Pernambuco and Rio Grande do Norte. During the period, 47 (3.48% out of 1.347 ascensions were reported as malformations. Based in the type of malformation and in the origin of the animals, malformations were divided in: 1 caused by the ingestion of M. tenuiflora, and 2 sporadic malformations of unknown causes. In sheep, 21 out of 418 ascensions were malformations, being 18 (4.3% of malformations caused by M. tenuiflora and 3 (0.71% of sporadic malformations. In cattle, 14 out of 434 ascensions were malformations, from these 8 (1.84% were caused by M. tenuiflora and 6 (1.38% were sporadic malformations. In goats, 12 out of 495 ascensions were malformations, being 9 (1.81% malformations related with the ingestion of M. tenuiflora and 3 (0.6% sporadic malformations. More frequent malformations caused by M. tenuiflora were arthrogryposis, micrognatia, palatoschisis, microphtalmia and unilateral or bilateral hypoplasia or aplasia of the incisive bones. Sporadic malformations were acephaly and hermaphrodite, dicephaly and malformations of mesenteric vessel in sheep; atresia ani in three goats; and hydranencephaly, atresia ani, ribs malformation with eventracion, cerebellar hypoplasia with hydrocephalus, pulmonary choristoma and meningocele, and siamese twins in cattle. A case of cerebellar hypoplasia with hydrocephalus was negative on immunohistochemistry to bovine viral diarrhea virus. Malformations caused by M. tenuiflora occurred during the whole year. The highest frequency in sheep seems to be associated with the consumption of the plant by ewes after first rains, in the first two months of gestation, when they are supplemented with concentrates, and M. tenuiflora is the main green forage available. Malformations occur mainly in degraded areas of native forest (caatinga invaded by M. tenuiflora, with lesser variety of other species.

    The etiology of congenital scoliosis and its development remains unclear and has not yet been fully identified, even there are theories that congenital scoliosis could be derived from the failure of formation or failure of segmentation, which are etiologically heterogeneous with genetic, epigenetic, and environmental factors contributing to their occurrence. We reported a case of long-term follow-up after posterior vertebral column resection (PVCR) in both identical twins with similar congenital kyphoscoliosis at thoracolumbar levels. Twin I had been noticed by his parents to have asymmetry of his back at age 5 years, but no treatment was given. Twin II was first noticed to have a spinal problem at 11 years of age by his parents. Overtime, spine of both twins became further deviated to the left with kyphosis and was referred to our hospital. Both monozygotic twins were treated by PVCR and satisfactory results were demonstrated at 10-year follow-up.This case is the first report on the surgical treatment with PVCR, almost simultaneously, in both identical twins who had similar congenital vertebral anomalies causing kyphoscoliosis. Both identical twins with congenital kyphoscoliosis had undergone surgical correction by PVCR, anterior support with a mesh cage and posterior fusion using pedicle screws at the age of 14 years and achieved a satisfactory correction and a stable spine without curve progression with 10-year follow-up.

    Full Text Available Split cord malformations are rare form of occult spinal dysraphism in children. Split cord malformations are characterized by septum that cleaves the spinal canal in sagittal plane within the single or duplicated thecal sac. Although their precise incidence is unknown, split cord malformations are exceedingly rare and represent %3.8-5 of all congenital spinal anomalies. Characteristic neurological, urological, orthopedic clinical manifestations are variable and asymptomatic course is possible. Earlier diagnosis and surgical intervention for split cord malformations is associated with better long-term fuctional outcome. For this reason, diagnostic imaging is indicated for children with associated cutaneous and orthopedic signs. Additional congenital anomalies usually to accompany the split cord malformations. Earlier diagnosis, meticuolus surgical therapy and interdisciplinary careful evaluation and follow-up should be made for good prognosis. [Cukurova Med J 2015; 40(2.000: 199-207

In a cohort reduced to 41,337 mother-child pairs for technical reasons, mean birth weight and perinatal mortality rates were similar according to exposure or nonexposure to either drug, as were intelligence quotient scores measured at four years of age in 28,358 of the children. Control of potential confounding factors with a variety of multivariate techniques did not materially alter these findings. PMID:879205

  8. Three-dimensional display of the ventricles and cisterns from routine, non-contrast-enhanced CT scans: Hydrocephalus and congenital malformations

    International Nuclear Information System (INIS)

    Standard image data from routine head CT scans can now be reprocessed in minutes to display cerebrospinal fluid free from surrounding brain and bone without need for any contrast agent(s). The three-dimensional, volumetric images generated can then be manipulated in seconds for visualization of the ventricles from any angle, or to yield cut-plain sections for visualization of the midline or other areas of interest. Based on a analysis of 50 cases, three-dimensional display of the size, position, and configuration of the ventricles materially aids the CT-based diagnosis of hydrocephalus, shunt malfunctions, and congenital malformations such as Dandy-Walker cyst, holoprosencephaly, and callosal agenesis with cyst

  9. Frequency and structure of congenital malformations of development as markers of teratogen and mutagen radiation effects in a populations of a diverse radiation risk

    International Nuclear Information System (INIS)

    The principal task of this study is consideration of possible mutagenic and teratogenic effects of ionizing radiation on the dynamics, frequency and structure of congenital malformations of development (CMD) of newborns in rural populations of a diverse radiation risk. Analysis of dynamics of CMD spatial-temporal performances reveals the steady temporal trend to their growth in the posterity of irradiated persons and territorial build up of CMD frequency in populations geographically close to the Semipalatinsk test site. It is determined the high correlation frequency relation of CMD separate forms with population effective radiation dose (r=0.72-0.81) and considerable exposure of main population-genetic indexes (r=0.52-0.89). It is revealed population mutagenic and teratogenic effects of prolonged ionizing radiation effect on the frequency of germinal chromosomal and genome mutation in population of extremely high and maximal radiation risk

OBJECTIVE: To verify the frequency of OAVS in a sample of patients with major heart malformations. METHODS: We evaluated a prospective cohort of patients with CHD admitted in a pediatric cardiac intensive care unit (ICU in Brazil. The diagnosis of OAVS was made based on the clinical data, considering standard criteria. The patients that met these criteria were submitted to high resolution GTG-Banding karyotype and fluorescence in situ hybridization for 22q11.2 microdeletion. Fisher's exact test (P < 0.05 was used for the statistical analysis. RESULTS: During the period of evaluation, 330 patients were hospitalized for the first time in the ICU, but thirty of them did not participate in the study. Of the 300 patients that constituted the final sample, OAVS was verified in 3 cases (1%. All presented normal cytogenetic studies. CONCLUSION: OAVS seems to be a frequent condition among patients with CHDs. However, we cannot exclude the possibility that the frequency of OAVS found in our study might have been underestimated due to the low rate of prenatal detection of CHDs and the limited access of patients to appropriate health care in our region. Future prospective studies with well defined clinical criteria and subjects with mild and major defects will be important to assess the role of OAVS in the general population of subjects with heart malformations.

    We hypothesized that susceptibility to the genetic and environmental factors that disrupt cardiac development is associated with race and sex. To evaluate this hypothesis, we asked whether the prevalence of specific cardiac malformations differs by race and sex. We attempted to include all infants born alive in the State of Louisiana from January 1, 1988, through December 31, 1989, and diagnosed by echocardiography, catheterization and/or autopsy within a year of birth as having one of ten specific cardiac malformations. The prevalence of atrioventricular canal defects (AVCD) per 1,000 live births was significantly higher for black females (.744) compared to black males (.198) and for white females (.414) compared to white males (.116). Complete transposition of the great arteries (TGA) was significantly higher for white males (.559) compared to white females (.122); in contrast, TGA was not significantly different for black males (.198) and black females (.169). Obstructive left heart syndrome (OLHS)--aortic stenosis and/or coarctation of the aorta--was significantly higher for white males (.652) compared to white females (.317); in contrast, OLHS was not significantly different for black males (.264) and black females (.169). Single ventricle (SV) was significantly higher for whites (.202) compared to blacks (.067). We did not find that race and sex were associated with differences in the prevalence of tetralogy of Fallot and hypoplastic left heart syndrome. The numbers of infants with anomalous pulmonary venous return, tricuspid atresia, double outlet right ventricle, or truncus arteriosus were too small to measure an association with race and sex. These results demonstrate that the prevalence of a subset of cardiac malformations differs by race and sex.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1523585

Comparison tests were carried out in order to assess the significant differences among the various regions and the correlations between indicators, and of these with the departmental latitudes and longitudes. RESULTS: There was no significant correlation between the IMRCM and the SDEI, nor with geographic coordinates. However, there was a significant positive correlation between the IMRCM and the SDEI (P < 0.05 at all levels of political organization. The SDEI explained 41% of the %DCM. CONCLUSIONS: The IMRCM was not significantly associated with the country's marked socioeconomic heterogeneity; the highest %DCM values, on the other hand, were observed in the populations of the central and southern areas of the country. Given the relationship between the %DCM and socioeconomic development of the population, use of this indicator as a proxy of well-being and quality of life is suggested.

  19. Cerebral malformations without antenatal diagnosis

    International Nuclear Information System (INIS)

    Cerebral malformations are usually described following the different steps in development. Disorders of neurulation (dysraphisms), or diverticulation (holoprosencephalies and posterior fossa cysts), and total commissural agenesis are usually diagnosed in utero. In contrast, disorders of histogenesis (proliferation-differentiation, migration, organization) are usually discovered in infants and children. The principal clinical symptoms that may be a clue to cerebral malformation include congenital hemiparesis, epilepsy and mental or psychomotor retardation. MRI is the imaging method of choice to assess cerebral malformations. (orig.)

    The region 21q22 is considered crucial for the pathogenesis of both Down syndrome (DS) and the partial monosomy 21q syndrome. Haploinsufficiency of the RUNX-1 gene, mapping at 21q22 is responsible for a platelet disorder and causes predisposition to myelodysplastic syndrome (MDS). We describe a 3-year-old girl with mental retardation, congenital heart malformation, and subtle dysmorphic facial features. The patient developed thrombocytopenia when she was 2 years old. Bone marrow smear led to the diagnosis of myelodysplasia. Prenatal karyotyping had shown chromosome 21 pericentric inversion. Postnatally the array-CGH revealed duplication at bands 21q11.2-21q21.1 and a simultaneous deletion involving the region 21q22.13-21q22.3. RUNX-1 mRNA levels analyzed in patient's skin fibroblasts were reduced. In this child the monosomy of the region 21q22 likely had the main role in determining the phenotype. Although the RUNX-1 gene is localized outside the deleted region, we speculate that RUNX-1 reduced expression, is probably due to the deletion of regulatory factors and caused the hematologic disorder in the patient. The present report underlines also the importance of array-CGH in characterizing patients with a complex phenotype. PMID:21671372

    A total population of 2,52,735 was surveyed (1,24,246 males, 1,28,489 females; (sex ratio 1000:1034). congenital malformation was reported among 2951 individuals with a frequency of 1.17%. The percentage of individuals with birth defects ranged from 1% in Oachira to 1.46% in Neendakara. At least one of the late onset diseases were reported in 33,199 (13.14%) individuals. Percentage of individuals with any of the late onset diseases ranged from 10.7% in Panmana to 17.9% in Alappad. The distribution of birth defects is the eight panchayats is similar (both Kruskal Wallis and median test P > .20) whereas the distribution of late onset disease does not appear to be similar in all the panchayats (Kruskal Wallis chi-square with 7 d.f = 32.3, P < .001; median test chi-square with 7 d.f. = 15.1; P= .035). The frequency of late onset diseases among males and females in different age groups suggest that females in the age group of 30-59 report more late onset disease than their male counterparts

    Rectal atresia and anal stenosis are rare forms of anorectal malformations. The aim of the definitive surgical repair in such cases is to preserve the anal canal, the dentate line, and the sphincter complex. We present a case of rectal atresia and anal stenosis to demonstrate the differences in the operative repair. The techniques described leave the anterior wall of the very distal anal canal untouched in both rectal stenosis and anal atresia; however, the dissection of the rectum differs. The atretic rectum in rectal atresia is mobilized and sutured to the anal canal circumferentially. In anal stenosis, the posterior rectum is mobilized in the form of rectal advancement, and the posterior 180° is anastomosed directly to the skin (as in a standard PSARP) with preservation of the anal canal as the anterior 180° of the final anoplasty. These patients have an excellent prognosis for bowel control and fecal continence, and therefore, complete mobilization and resection of the anal canal must be avoided. PMID:26902368

    Full Text Available Anorectal malformations (ARMs are among the more frequent congenital anomalies encountered in paediatric surgery, with an estimated incidence ranging between 1 in 2000 and 1 in 5000 live births. Antenatal diagnosis of an isolated ARM is rare. Most cases are diagnosed in the early neonatal period. There is a wide spectrum of presentation ranging from low anomalies with perineal fistula having simple management to high anomalies with complex management. Advances in the imaging techniques with improvement in knowledge of the embryology, anatomy and physiology of ARM cases have refined diagnosis and initial management. There has been marked improvement in survival of such patient over the last century. The management of ARM has moved forward from classical procedures to PSARP to minimal invasive procedures. But still the fecal and urinary incontinence can occur even with an excellent anatomic repair, mainly due to associated problems. There has been a paradigm shift in approach to these patients which involves holistic approach to the syndrome of Anorectal malformations with a long term goal of achievement of complete fecal and urinary continence with excellent quality of life.

METHODS: a longitudinal study was performed from September 2004 to May 2005 with all deliveries at the Instituto Materno Infantil Prof. Fernando Figueira, IMIP analyzed. The type and incidence of congenital malformations were determined, and fetal mortality, perinatal mortality, early and late neonatal mortality coefficients were calculated. RESULTS: malformation incidence was of 2.8% (in 4.043 births. Malformation percentages among live births was of 2.7% and among stillbirths of 6.7%. The most frequent malformations involved the central nervous system (principally hydrocephaly and meningomyelocele, the skeletal and muscular system and cardiopathies. There was no association between malformation and gender, but prematurity and low birthweight were more frequent among the malformation cases. It was determined that among malformed infants early neonatal mortality was of 32.7% and late neonatal mortality was of 10.6%. Malformation cases were 6.7% of stillborn babies, 24.2% of early neonatal deaths and 25.8% the total of neonatal deaths. CONCLUSIONS: malformation incidence corresponded to 2.8% of the births. Malformation was the second more frequent neonatal death cause following prematurity.

    Mutations in more than a hundred genes have been reported to cause X-linked recessive intellectual disability (ID) mainly in males. In contrast, the number of identified X-linked genes in which de novo mutations specifically cause ID in females is limited. Here, we report 17 females with de novo loss-of-function mutations in USP9X, encoding a highly conserved deubiquitinating enzyme. The females in our study have a specific phenotype that includes ID/developmental delay (DD), characteristic facial features, short stature, and distinct congenital malformations comprising choanal atresia, anal abnormalities, post-axial polydactyly, heart defects, hypomastia, cleft palate/bifid uvula, progressive scoliosis, and structural brain abnormalities. Four females from our cohort were identified by targeted genetic testing because their phenotype was suggestive for USP9X mutations. In several females, pigment changes along Blaschko lines and body asymmetry were observed, which is probably related to differential (escape from) X-inactivation between tissues. Expression studies on both mRNA and protein level in affected-female-derived fibroblasts showed significant reduction of USP9X level, confirming the loss-of-function effect of the identified mutations. Given that some features of affected females are also reported in known ciliopathy syndromes, we examined the role of USP9X in the primary cilium and found that endogenous USP9X localizes along the length of the ciliary axoneme, indicating that its loss of function could indeed disrupt cilium-regulated processes. Absence of dysregulated ciliary parameters in affected female-derived fibroblasts, however, points toward spatiotemporal specificity of ciliary USP9X (dys-)function. PMID:26833328

According to the Latin American Collaborative Study for Congenital Malformations (ECLAMC, its frequency is 4.1 per 10,000 born alive. Aim: To determine the frequency of anorectal malformations at birth, and compare the figures with those of other maternity hospitals in Chile participating in ECLAMC, with the figures of the whole ECLAMC and with figures from other worldwide monitoring systems. Patients and methods: All births occurred in the University of Chile Clinical Hospital between January 1979 and August 1999, were reviewed. Results: During the study period, 70,242 children were born, 4,486 had a malformation and 54 had an anorectal malformation (7.7 per 10,000 born alive. Fifty nine percent had other associated malformations (of the urinary tract in 42.5%, skeletal in 26% and cardiovascular in 18.5%. Five stillborn babies had other severe malformations. Twenty one children had a fistula. Forty three % were male, 39% female and 18% had ambiguous sex. When compared with normal controls, malformed newborns had a lower birth weight, lower gestational age and a higher mean maternal age, a higher frequency of metrorrhagia during the first trimester of pregnancy, a higher number of siblings with malformations and a higher degree of consanguinity among parents. Conclusions: The participation of recessive genes in the etiology of anorectal malformations is suggested. (Rev Méd Chile 2000; 128: 519-25

    Full Text Available bjective: Congenital hypothyroidism is characterized by inadequate thyroid hormone production in newborn infants. Many infants with CH have co-occurring congenital malformations. This is an investigation on the frequency and types of congenital anomalies in infants with congenital hypothyroidism born from May 2006-2010 in Hamadan, west province of Iran.Methods: The Iranian neonatal screening program for congenital hypothyroidism was initiated in May 2005. This prospective descriptive study was conducted in infants diagnosed with congenital hypothyroidism being followed up in Pediatric Endocrinology Clinicof Besat Hospital, a tertiary care centre in Hamadan. Cases included all infants with congenital hypothyroidism diagnosed through newborn screening program or detected clinically. Anomalies were identified by clinical examination, echocardiography, and X-ray of the hip during the infant’s first year of life.Results: A total of 150 infants with biochemically confirmed primary congenital hypothyroidism (72 females and 78 males were recruited during the period between May 2006-2010. Overall, 30 (20% infants had associated congenital anomalies. The most common type of anomaly was Down syndrome. Seven infants (3.1% had congenital cardiac anomalies such as: ASD (n=3, VSD (n=2, PS (n =1, PDA (n=1. Three children (2.6% had developmental displasia of the hip (n=3.Conclusion: The overall frequency of Down syndrome, cardiac malformation and other birth defect was high in infants with CH. This reinforces the need to examine all infants with congenital hypothyroidism for the presence of associated congenital anomalies.

    Vascular anomalies are a heterogeneous group of congenital blood vessel disorders more typically referred to as birthmarks. Subcategorized into vascular tumors and malformations, each anomaly is characterized by specific morphology, pathophysiology, clinical behavior, and management approach. Hemangiomas are the most common vascular tumors. Lymphatic, capillary, venous, and arteriovenous malformations make up the majority of vascular malformations. Arteriovenous malformation of the head and neck is a rare vascular anomaly but when present is persistent and progressive in nature and can represent a lethal benign disease. Here we present a case report of a 25-year-old male patient with arteriovenous malformation involving the base of tongue. PMID:24660070

  16. Supratentorial CNS malformations

    International Nuclear Information System (INIS)

    Full text: Clinical suspicion of a developmental anomaly of the central nervous system (CNS) is a frequent indication for performing and magnetic resonance imaging (MRI) examination of the brain. Classification systems for malformation of the CNS are constantly revised according to newer scientific research. Developmental abnormalities can be classified in two main types. The first category consists of disorders of organogenesis in which genetic defects or any ischemic, metabolic, toxic or infectious insult to the developing brain can cause malformation. These malformations result from abnormal neuronal and glial proliferation and from anomalies of neuronal migration and or cortical organization. They are divided into supra- and infratentorial and may involve grey or white matter or both. The second category of congenital brain abnormalities is disorders of histogenesis which result from abnormal cell differentiation with a relatively normal brain appearance. Supratentorial CNS malformations could be divided into anomalies in telencephalic commissure, holoprosencephalies and malformations in cortical development. There are three main telencephalic commissures: the anterior commissure, the hippocampal commissure and the corpus callosum. Their morphology (hypoplasia, hyperplasia, agenesis, dysgenesis, even atrophy) reflects the development of the brain. Their agenesis, complete or partial, is one of the most commonly observed features in the malformations of the brain and is a part of many syndromes. Malformations of cortical development (MCD) are heterogeneous group of disease which result from disruption of 3 main stages of cortical development. The common clinical presentation is refractory epilepsy and or developmental delay. The most common MCD are heterotopias, focal cortical dysplasia, polymicrogyria, schizencephaly, pachygyria and lizencephaly. The exact knowledge of the brain anatomy and embryology is mandatory to provide a better apprehension of the pathogenetic processes leading to the disorder in a given patient. Certain anomalies previously thought to be isolated have proven to be associated with one or more other brain malformations. When one CNS malformation is found expanded scrutiny of the whole of the whole brain for further anomalies is required. Learning objectives: 1) To describe what the radiologist should know about supratentorial anatomy and embryology; 2) To discuss some of the pitfalls in MR imaging in malformations of cortical development; 3) To show the spectrum of imaging findings of supratentorial CNS malformations

    Full Text Available Se define como malformación congénita mayor a los defectos que tienen un compromiso funcional o estético importante para la vida del individuo, por lo que tienen consecuencias médicas, requieren de atención temprana, algunas veces de urgencia y, por tanto, tienen también repercusión psicosocial. Se realizó un estudio analítico de casos y controles con el objetivo de clasificar las malformaciones congénitas mayores que incidieron en la mortalidad infantil o fetal en el municipio de Ranchuelo, en el período de enero de 1999 a diciembre de 2003, para determinar la efectividad de los diferentes métodos de diagnóstico prenatales e identificar los factores de riesgo que se asociaron a estas. El universo de trabajo quedó constituido por 25 casos (21 mujeres con historia de interrupción de la gestación por causa genética y 4 con antecedentes de al menos un hijo(a fallecido por malformaciones congénitas y se seleccionó igual cantidad de controles. Las malformaciones que más incidieron fueron las del sistema nervioso, digestivo y genitourinario. La efectividad del ultrasonido en el diagnóstico prenatal fue de 88 % y cuando se combinó con la cuantificación de Alfafeto proteína en suero materno, fue de un 100 % para el diagnóstico de los defectos congénitos abiertos. Los factores de riesgo que se asociaron con las malformaciones fueron los antecedentes familiares de estos defectos, los hábitos tóxicos y los antecedentes de amenaza de aborto, con un riesgo atribuible de 0.46, 0.37 y 0.32, respectivamente. Se hacen recomendaciones.Congenital malformation is defined as the defects having an important functional or aesthetic compromise for the individual's life, so they have medical consequences, require early attention, sometimes of emergency and, therefore, they also have a psychosocial impact. An analytical case-control study was conducted aimed at classifying the major congenital malformations influencing on children or fetal mortality in Ranchuelo municipality from January 1999 to December 2003 to determine the effectivity of the different prenatal diagnostic methods and to identify the risk factors associated with them. The working universe was composed of 25 cases (21 women with history of abortion due to genetic cause and 4 with previous history of at least a dead child as a result of congenital malformations. The same number of controls was selected. The malformations affecting the most were those of the nervous, digestive and genitourinary system. The efficacy of ultrasound in the prenatal diagnosis was 88 %, and when it was combined with the quantification of alpha fetoprotein in maternal serum it was 100 % for the diagnosis of the open congenital defects. The risk factors associated with malformations were previous family history of these defects, the toxic habits and the antecedents of threatened abortion with an attributable risk of 0.46, 0.37 and 0.32, respectively.

RESULTADOS: Entre 1980 y 2005, la tasa de mortalidad infantil en México descendió de 40,7 a 16,9 por 1 000 nacimientos (β = -0,86; P OBJECTIVES: To evaluate the role that Mexico's National Health System (Sistema Nacional de Salud-SNS has played in the task of reducing the number of deaths due to congenital malformations through a trends analysis of cause-specific infant mortality rates (IMRcs. METHODS: Time-series analysis of deaths of boys and girls under 1 year of age from 1980-2005, according to databases of national and annual mortality maintained by the Secretariat of Health of Mexico. Cause-specific mortality rates were calculated for the most frequently occurring, severe, congenital malformations in Mexico: neural tube defects, diaphragmatic hernias, exomphalos (omphalocele and gastroschisis, and heart and digestive tract defects, grouped according to severity, degree of technological sophistication required for treatment, and most frequent outcome. RESULTS: From 1980-2005, the infant mortality rate in Mexico decreased from 40.7 to 16.9 per 1 000 births (β = -0.86; P < 0.001; however, the mortality rate for congenital malformations rose from 2.2 to 3.5 per 1 000 births (β = 0.05; P < 0.001. Only infantile hypertrophic pyloric stenosis and anorectal atresia, anomalies with good prognoses and treatments available in minimally-equipped facilities, exhibited downward trends in their IMRcs (β = -0.01 to -0.09; P < 0.001; while malformations requiring immediate treatment in specialized facilities showed rising IMRcs (β = 0.03 to 0.05; P < 0.001. CONCLUSIONS: The development of Mexico's SNS from 1980-2005 has not translated into a reduction of mortality from congenital malformations; this deficiency was more pronounced for anomalies that require immediate treatment and sophisticated technology.

    Full Text Available Background: Anomalous vertebral arteries (VAs, commonly involving the persistent first intersegmental artery (FIA, are often seen with congenital atlantoaxial dislocations (AAD. Here we describe an unusual variant consisting of bilateral VAs with normal loops but passing below the C1 (inverted VA arch, distinctly different from the FIA. Case Description: A 9-year-old boy presented with a spastic quadriparesis. Preoperative radiographic studies showed an irreducible AAD with an occipitalized CO-C1 and C2-3 fusion. Although both VAs exhibited proximal and distal loops like normal VA, the distal loops did not pass through the C1 transverse foramina and coursed inferior to the C1 arch instead. With this critical preoperative information, both VAs could be better safeguarded during dissection of the C1-2 facets. Conclusion: In the case presented, although the course of the inverted VAs is similar, the norm, they coursed inferior to both C1 arches. Careful evaluation of the preoperative radiological studies allowed for careful dissection of the inverted VA (horizontal loop while opening the C1-2 joint for subsequent alignment (e.g. reduction and bony fusion. This information also facilitates safer insertion of lateral mass screws (e.g. choosing the appropriate C1 screw length to gain adequate bony purchase without compromising anomalous VA.

  7. The association of congenital neuroblastoma and congenital heart disease

    International Nuclear Information System (INIS)

    Several authors have reported an association between neuroblastoma and congenital heart disease; others contend that, unlike specific wellknown associations between malignancy and congenital defects (Wilm's tumor and aniridia, leukemia and Down's syndrome), no real relationship exists. We present three cases of cyanotic congenital heart disease in which subclinical neuroblastoma was found. We speculate that abnormal neural crest cell migration and development may be a common link between cardiac malformations and congenital neuroblastoma. (orig.)

  8. Congenital malformations induced by ionizing radiation in mouse embryos: investigating molecular changes. Doctoral Thesis Prepared at SCK-CEN and Defended in 2006

    International Nuclear Information System (INIS)

    Irradiation of the mammalian embryo during development results in diverse effects depending on the dose and the specific gestational phase at irradiation. In this work cellular and molecular changes associated with X-irradiation of embryos were therefore investigated at both early and late gestational stages at the moment of radiation exposure. Our goal was to find biological markers indicative of teratogenic effects of radiation, and provide a holistic model of the impact of irradiation during early and late development. In the first part of this doctoral thesis, we investigated telomere length in the irradiated and non-irradiated embryos bearing different p53 genotypes and malformation status as telomere shortening was associated with neural tube defects in mTR-/- embryos. Moreover, the loss of telomere function has been shown to elicit DNA damage checkpoints and p53-dependent apoptosis in vitro. We conclude that telomere shortening is associated with the malformation status as well with the p53 genotype. These data assign telomere length as a potential predictor of a malformed phenotype, a feature that is modulated according to the p53 genotype and the developmental stage at the moment of irradiation. In the second part of this work, we focused on a specific malformation phenotype, namely: forelimb defect. To identify potential genes involved in the radiation-induced forelimb teratogenesis, we investigated differential gene expression between irradiated and non-irradiated fetuses using RT-q-PCR. The results indicate that forelimb defects observed in p53 wild type fetuses irradiated at the organogenesis period was due to excessive cellular death as shown by the high expression of the pro-apoptotic factors caspase-3 and Bax. This suggestion was supported by the positive TUNEL assay performed on forelimb tissue sections of malformed irradiated fetuses. Moreover, overexpression in malformed fetuses of MKK3 and MKK7, both members of the stress-activated MAP kinase family, could be involved in radiation-induced apoptosis through activation of the p38 and JNK pathways, respectively. To further evaluate the biomarker value of telomere length in this forelimb defect phenotype, we assessed telomere length in normal fetuses versus abnormal ones with forelimb defects. We found that irradiated fetuses exhibiting forelimb defects showed a marked telomere shortening confirming our first findings, which showed an association between various malformations and telomere shortening. Knowing that oxidative stress and inflammation are potential accelerators of telomere attrition, and taking into account that amniotic fluid is the most accessible fetal material, we decided to explore cytokine secretion in the amniotic fluid of normal and malformed fetuses. Our results showed a considerable inflammatory reaction among the irradiated fetuses, as revealed by the high presence of pro-inflammatory cytokines. Finally, all these results indicate that insufficiency or excess of apoptosis is probably the central process behind radiation-induced malformations. Moreover, apoptosis is strongly related to p53, which upon signaling modulates cell death response according to the developmental stage at which exposure to radiation has occurred. Furthermore, in the context of this work, telomere shortening as well as the differential gene expression described and the high pro-inflammatory cytokines measured may constitute potential indicators of the teratogenic status of the embryos after radiation exposure

    Full Text Available La malformación congénita de la vía aérea pulmonar (MCVAP, llamada también malformación congénita adenomatoidea quística que compromete al pulmón es una anomalía embrionaria. La MCVAP es de rara presentación en la infancia y es excepcional en los adultos. En este artículo comunicamos el caso de un hombre adulto con MCVAP y presentamos una breve revisión sobre esta condición. Caso clínico: Hombre de 23 años de edad con varios episodios de neumonía y de síndrome bronquial obstructivo en su niñez. El paciente se quejaba de dolor torácico pleurítico, malestar general y fiebre. En el examen físico se encontró disminución del murmullo pulmonar en la parte inferior del hemitórax derecho, abundantes crepitaciones y matidez. La radiografía y la tomografia computada de tórax (TC revelaron múltiples imágenes hidro-aéreas complejas en el pulmón derecho. Debido a la falta de respuesta al tratamiento médico, se practicó una lobectomía inferior derecha. La histopatología demostró una MCVAP tipo 1. Después de ser dado de alta el paciente presentó una fístula broncopleural, la cual fue tratada exitosamente con una segunda intervención quirúrgica. Tres años después de la cirugía el paciente está asintomático. Discusión: La MCVAP es una malformación congénita hamartomatosa muy poco frecuente. En adultos es excepcional. La técnica diagnóstica de elección es la TC de tórax. Considerando el alto potencial neoplásico de esta malformación, su tratamiento debe ser la resección quirúrgica, incluso si el paciente está asintomático.Congenital pulmonary airway malformation or CPAM (congenital cystic adenomatoid malformation that involve the lung is an embryonic anomaly.

Because of the lack of response to medical treatment a right lower lobectomy was performed. Histopathology revealed a type 1 CPAM. After being discharged from the hospital the patient developed a broncho-pleural fistula, that was succesfully treated by a second surgical intervention. Three years after surgery the patient is free of symptoms. Discussion: CPAM is a rare congenital hamartomatous condition. This malformation in adults it is exceptional. Chest CT is the choice diagnostic technique. Considering the high neoplastic potential of this malformation, its treatment should be the surgical resection, even in asymptomatic patients.

    Disorders of supratentorial cortical development are usually divided into disorders of neuronal proliferation, neuronal migration and cortical organization. Based upon molecular biologic discoveries, a modified classification has recently been proposed. The category of malformations of abnormal neuronal and glial proliferation and apoptosis now includes microlissencephalies, megalencephalies, hemimegalencephalies and cortical dysplasias with balloon cells. Malformations due to abnormal neuronal migration now subsume the lissencephaly spectrum including the subcortical band heterotopias, the cobblestone complex and the group of heterotopias. Malformations due to abnormal cortical organization include the spectrum of polymicrogyria and schizencephaly as well as cortical dysplasias without balloon cells. High-resolution magnetic resonance imaging (MRI) has led to an increasing awareness of these malformations. This article aims to illustrate the classification, MRI presentation and relevant clinical features of the most commonly encountered disorders of cortical development. (orig.) [German] Entwicklungsstoerungen des Kortex werden in der Regel eingeteilt in Stoerungen der zellulaeren Proliferation und Apoptose, der neuronalen Migration und der kortikalen Organisation. Basierend auf neueren molekularbiologischen und histopathologischen Erkenntnissen wurde vor kurzem eine modifizierte Klassifikation eingefuehrt. Zu den Stoerungen der neuronalen und glialen Proliferation und Apoptose werden nun die Mikrolissenzephalie und andere Formen der Mikrozephalie, die Megalenzephalien, die kortikalen Hamartome der tuberoesen Sklerose, die kortikalen Dysplasien mit Ballonzellen und die Hemimegalenzephalie gezaehlt. Zu den neuronalen Migrationsstoerungen rechnet man das Spektrum der Lissenzephalien, einschliesslich der bandfoermigen Heterotopien, die Pflastersteinlissenzephalien sowie die Gruppe der Heterotopien. Unter Organisationsstoerungen des Kortex subsumiert man den Komplex aus Polymikrogyrie und Schizenzephalie sowie die kortikalen Dysplasien ohne Ballonzellen. Hoch aufloesende magnetresonanztomographische Untersuchungen erlauben in zunehmendem Masse einen Nachweis der kortikalen Entwicklungsstoerungen. Dieser Artikel soll die MR-tomographischen Charakteristika und relevanten klinischen Symptome der Entwicklungsstoerungen des Kortex illustrieren. (orig.)

    Full Text Available Introducción. El Instituto de Genética Humana, de la Pontificia Universidad Javeriana, desarrolla un programa de vigilancia de malformaciones congénitas con metodologías modificadas del Estudio Colaborativo Latinoamericano de Malformaciones Congénitas.
    Objetivo. Describir la frecuencia de las principales malformaciones congénitas en el país.
    Materiales y métodos. Entre abril de 2001 y enero de 2008, se obtuvo información sobre los pacientes con malformaciones congénitas y se analizaron la edad materna, la edad de gestación, el sexo y el peso del neonato, y la malformación congénita. Se clasificaron los casos según una escala de pronóstico para evaluar el impacto de la intervención del equipo de salud en la evolución de estos pacientes.
    Resultados. De 52.744 nacimientos en tres ciudades, 3,12% presentó alguna malformación congénita. Las anomalías de la oreja fueron las más frecuentes. El pie equino varo, la polidactilia y el labio y paladar hendidos, afectaron más a los pacientes de sexo masculino. El peso y la edad de gestación fueron menores en el grupo de los casos que en el de los controles. La escala de pronóstico mostró un alto riesgo de mortalidad o discapacidad en 54% de los pacientes y reveló que la intervención del equipo de salud cambia el pronóstico en más de 80% de los casos.
    Conclusión. Las frecuencias encontradas son similares a las del resto del mundo. La intervención del equipo de salud debe influir en el pronóstico de estas patologías. Un manejo temprano, adecuado e interdisciplinario es vital para disminuir la discapacidad y mejorar la calidad de vida de estos pacientes.Introduction. The Instituto de Genética Humana of the Pontificia Universidad Javeriana conducted an epidemiological surveillance of congenital malformations as defined by criteria provided by the Latin American Collaborative Study of Congenital Malformations.
    Objective. The frequency of the main congenital malformations were tabulated for major urban centers in Colombia.
    Materials and methods. Information was gathered from 52,744 newborns between April 2001 and January 2008 in three cities of Colombia (Bogotá, Ubaté and Manizales. Data included the age of mother, gestational age, gender and weight of the newborn and the congenital malformation. Cases were classified according to a prognostic scale to assess the impact of health team interventions in the recovery process.
    Results. Congenital defects were noted in 3.1% of the newborns. The most frequent congenital defects were those of the ears. Clubfoot, polydactyly and cleft lip or palate were more common amongst males. The weight and gestational age were lower in the congenitally affected in comparison with the control group. The prognostic scale of congenital malformations indicated that most of these patients are at high risk of death or disability and that the intervention of the health team changed the patient´s prognosis in approximately 80% of the cases.
    Conclusion. Frequencies of congenital malformations in Colombia were similar to those reported in other countries. The interventions of the health team in treating patients with congenital malformations directly affected patient prognosis. Therefore, early diagnosis and adequate interdisciplinary treatment were recommended by these data in order to reduce disability and improve the quality of life of these patients.

    Full Text Available Background/Purpose: Anorectal malformations are one of the most common congenital defects. This study was undertaken to study the hospital incidence of anorectal malformations (ARM, frequency of various types of defects, their sex distribution and the spectrum of anomalies associated with ARM. The effect of presence of an associated defect on mortality and morbidity was also studied. Materials and Methods: One hundred consecutive children attending the pediatric surgery department were included in this study. A detailed history was taken, and examination was performed for the primary as well as the associated defects. Appropriate investigations like invertogram, cologram were done wherever indicated. Management was as per the standard protocol. The data was recorded and analyzed. Results: Out of the 100 patients, 51 were males and 49 females. One out of every 6.62 admission was for ARM. Twenty percent of the female babies had high, 76% intermediate and 4% had low anomalies, whereas 80.39% males had high, 3.92% intermediate and 15.6% showed low malformations. Ten percent of the patients had pouch colon. Associated anomalies were seen in 33 patients - 20 males and 13 females; 19 in high, 10 in intermediate, 1 in low group and 3 children with cloacal malformations. Associated defects seen were urogenital (17%, cardiovascular (7%, gastrointestinal (9%, genital (5% and limb defects (7%. There were 8 deaths, and complications were seen in 13 patients. Ten patients had two or more defects associated with ARM. Conclusions: Anorectal malformations occurred equally in males and females. Females had intermediate defects more frequently, rectovestibular fistula being the commonest. Males were more likely to have high lesions; anorectal agenesis without fistula was the commonest defect. The most common associated defects seen were vesicoureteric reflux and esophageal atresia. Complications were seen more commonly in males with high lesions. There was a significant association between presence of an associated defect and mortality and morbidity.

  17. A study on the progression of congenital scoliosis and the experimental production of the congenital scoliosis induced by 60Co irradiation in rats

    International Nuclear Information System (INIS)

    In order to clarify the pathological mechanism of the development of congenital spinal deformities, seventy six cases with congenital spinal deformity were analysed clinically, and vertebral anomalies were produced experimentally in rats of the Wistar strain by giving 60Co irradiation (200 R) to the mother in the ninth, tenth and eleventh days of the pregnancy. The congenital vertebral anomalies were classified embryologically into the following eight groups, (1) Wedge vertebra, (2) Fused wedge vertebra, (3) Hemivertebra, (4) Fused hemivertebra, (5) Unilateral segmental failure, (6) Bilateral segmental failure, (7) Butterfly vertebra and (8) Mixed type. Out of these anomalies, the unilateral segmental failure and the imbalanced multiple hemivertebrae and wedge vertebrae proved to show a marked development of the scoliotic deformities. Vertebral anomalies were confirmed in 26 of the 101 newborn infants whose mothers were treated with 60Co irradiation in the 10th or 11th day of the pregnancy. The vertebral anomalies were either unilateral segmental failure or butterfly vertebrae located mostly at the lower thoracic, lumbar or sacral spine. A scoliotic deformity of the spine developed during the rapid growth of the body in all rats with unilateral segmental failure. From the histological examinations, it was revealed that the asymmetrical potency of the growth in the malformed vertebra was a factor causing the spinal deformities. (auth.)

  4. Magnetic resonance imaging features of complex Chiari malformation variant of Chiari 1 malformation

    Complex Chiari malformation is a subgroup of Chiari 1 malformation with distinct imaging features. Children with complex Chiari malformation are reported to have a more severe clinical phenotype and sometimes require more extensive surgical treatment than those with uncomplicated Chiari 1 malformation. We describe reported MR imaging features of complex Chiari malformation and evaluate the utility of craniometric parameters and qualitative anatomical observations for distinguishing complex Chiari malformation from uncomplicated Chiari 1 malformation. We conducted a retrospective search of the institutional imaging database using the keywords ''Chiari'' and ''Chiari 1'' to identify children imaged during the 2006-2011 time period. Children with Chiari 2 malformation were excluded after imaging review. We used the first available diagnostic brain or cervical spine MR study for data measurement. Standard measurements and observations were made of obex level (mm), cerebellar tonsillar descent (mm), perpendicular distance to basion-C2 line (pB-C2, mm), craniocervical angle (degrees), clivus length, and presence or absence of syringohydromyelia, basilar invagination and congenital craniovertebral junction osseous anomalies. After imaging review, we accessed the institutional health care clinical database to determine whether each subject clinically met criteria for Chiari 1 malformation or complex Chiari malformation. Obex level and craniocervical angle measurements showed statistically significant differences between the populations with complex Chiari malformation and uncomplicated Chiari 1 malformation. Cerebellar tonsillar descent and perpendicular distance to basion-C2 line measurements trended toward but did not meet statistical significance. Odontoid retroflexion, craniovertebral junction osseous anomalies, and syringohydromyelia were all observed proportionally more often in children with complex Chiari malformation than in those with Chiari 1 malformation. Characteristic imaging features of complex Chiari malformation, especially obex level, permit its distinction from the more common uncomplicated Chiari 1 malformation. (orig.)

    The International Society for Study of Vascular Anomalies (ISSVA) broadly categorizes vascular anomalies as vascular tumors or vascular malformations. The latter are congenital lesions that are further categorized by their flow properties and include high-flow arteriovenous malformations, slow-flow venous and lymphatic malformations, and congenital mixed syndromes, which can include a combination of malformations. Unlike vascular tumors, vascular malformations never regress and can persist and grow for the duration of the patient's lifespan. As our understanding of the natural history, hemodynamics, and treatment outcomes of these lesions has expanded and evolved over the last few decades, certain fundamental diagnostic and therapeutic principles have been established and are considered standard of care. These overarching principles are crucial to adhere to in the overall management of these lesions and are highlighted and expanded on in this report, which focuses exclusively on peripheral slow-flow venous and lymphatic malformations.

    Duplicons, that is, DNA sequences with minimum length 10 kb and a high sequence similarity, are known to cause unequal homologous recombination, leading to deletions and the reciprocal duplications. In this study, we designed a Multiplex Amplifiable Probe Hybridisation (MAPH) assay containing 63 exon-specific single-copy sequences from within a selection of the 169 regions flanked by duplicons that were identified, at a first pass, in 2001. Subsequently, we determined the frequency of chromosomal rearrangements among patients with developmental delay (DD) and/or congenital malformations (CM). In addition, we tried to identify new regions involved in DD/CM using the same assay. In 105 patients, six imbalances (5.8%) were detected and verified. Three of these were located in microdeletion-related regions, two alterations were polymorphic duplications and the effect of the last alteration is currently unknown. The same study population was tested for rearrangements in regions with no known duplicons nearby, using a set of probes derived from 58 function-selected genes. The latter screening revealed two alterations. As expected, the alteration frequency per unit of DNA is much higher in regions flanked by duplicons (fraction of the genome tested: 5.2%) compared to regions without known duplicons nearby (fraction of the genome tested: 24.5-90.2%). We were able to detect three novel rearrangements, including the previously undescribed reciprocal duplication of the Williams Beuren critical region, a subduplicon alteration within this region and a duplication on chromosome band 16p13.11. Our results support the hypothesis that regions flanked by duplicons are enriched for copy number variations. PMID:16391556

    Abstract Background The use of assisted reproductive techniques (ART) for treatment of infertility is increasing rapidly worldwide. However, various health effects have been reported including a higher risk of congenital malformations. Therefore, we assessed the risk of anorectal malformations (ARM) after in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Methods Data of the German Network for Congenital Uro-REctal malformations (CURE-Net) were compared to nationwide da...

  1. Dural arteriovenous malformations

    International Nuclear Information System (INIS)

    The management of arteriovenous malformations confined exclusively to the dura and its duplications (DAVMs) is a challenge. The problems of diagnosis and the possible methods of treatment are discussed on the basis of 23 personal cases. Selective and superselective angiography for the detection of any multipedicular supply from separate arterial systems has proved essential before rational treatment can be instituted. Usually it is not possible to cure DAVMs by embolization alone: the approach now used for the main feeders arising from branches of the internal carotid and vertebral arteries is inadequate. However, it is usually possible to reduce the volume of the shunt flow and the pressure in the draining sinuses. Frequently the success is only temporary and a combined surgical and intravascular procedure is later necessary. In isolated cases, inoperable DAVMs can be transformed to operable ones by first performing embolization. (orig.)

CONCLUSÕES: Os resultados deste trabalho mostram elevada prevalência de anomalias cardíacas congênitas em nosso meio e distribuição e associações semelhantes às observadas em países desenvolvidos. A elevada mortalidade associada a essas anomalias alerta para a necessidade de pesquisas mais abrangentes a fim de se conhecer os fatores de risco e buscar a prevenção primária de alguns desses defeitos.BACKGROUND: In Brazil, since 2001, the congenital abnormalities have represented the second cause of death in children younger than one year, with cardiovascular defects being responsible for 39.4% of these deaths. OBJECTIVES: To establish the prevalence and the characteristics of the congenital cardiac malformations in pediatric necropsies performed in Hospital Regional da Asa Sul, Brasília, DF, Brazil, from January 1996 to December 2007. METHODS: This is a descriptive, cross-sectional study that reviewed 1,591 necropsies performed from January 1996 to December 2007 and found 189 (11.9% with congenital cardiac malformations, included in this study. RESULTS: The cardiac abnormalities were observed mainly in the group of live births (117/61.9%, followed by the stillbirths (35/18.5%, the infant group (30/15.9% and the preschoolers' group (7/3.7%, with no cases identified among school-aged children. The main alterations detected were: interatrial communication in 96 patients (27%, interventricular communication in 66 patients (18.5% and patent ductus arteriosus in 51 (14.3%, with no predominance of either sex. In 133 patients (70.4%, the cardiopathies were multiple and in 96 (50.8% they were associated with anomalies in other organs and systems; among these, 45 (23.8% presented cardiopathies as syndrome components, especially trisomies, at all age ranges. CONCLUSIONS: The results of the present study show a high prevalence of congenital cardiac anomalies in our country and distribution and association that were similar to the ones observed in developed countries. The high mortality associated to such anomalies highlights the need for more comprehensive research in order to identify the risk factors and seek the primary prevention of some of these defects.

    We aim to review the magnetic resonance imaging appearance of malformations of midbrain and hindbrain. These can be classified as predominantly cerebellar malformations, combined cerebellar and brain stem malformations, and predominantly brain stem malformations. The diagnostic criteria for the majority of these morphological malformations are based on neuroimaging findings. The predominantly cerebellar malformations include predominantly vermian hypoplasia seen in Dandy-Walker malformation and rhombencephalosynapsis, global cerebellar hypoplasia reported in lissencephaly and microlissencephaly, and unilateral cerebellar hypoplasia seen in PHACES, vanishing cerebellum, and cerebellar cleft. Cerebellar dysplasias are seen in Chudley-McCullough syndrome, associated with LAMA1 mutations and GPR56 mutations; Lhermitte-Duclos disease; and focal cerebellar dysplasias. Cerebellar hyperplasias are seen in megalencephaly-related syndromes and hemimegalencephaly with ipsilateral cerebellomegaly. Cerebellar and brain stem malformations include tubulinopathies, Joubert syndrome, cobblestone malformations, pontocerebellar hypoplasias, and congenital disorders of glycosylation type Ia. Predominantly brain stem malformations include congenital innervation dysgenesis syndrome, pontine tegmental cap dysplasia, diencephalic-mesencephalic junction dysplasia, disconnection syndrome, and pontine clefts.

    Horseshoe lung is a congenital pulmonary malformation that is usually associated with scimitar syndrome. This malformation consists of fusion of both pulmonary lobes from the posterobasal segments. The fusion appears in the retrocardiac area, in front of the esophagus and thoracic aorta. Pleural separation of pulmonary lobes distinguishes pseudohorseshoe appearance from a true horseshoe lung. Scimitar syndrome known as hypogenetic lung syndrome is a part of the congenital pulmonary venolobar ...

  6. Evolutionary origin of cardiac malformations.

    Science.gov (United States)

    Taussig, H B

    1988-10-01

    The author has proposed in previous publications that isolated cardiac malformations have an evolutionary origin. This is partly supported by the fact that isolated cardiac malformations found in humans occur also in other placental mammals as well as in birds. External gross examination of the heart in just over 5,000 birds was carried out during a 3 year period. Anomalies included one instance of duplicate hearts, two specimens in which no heart could be identified and in a fourth, a yellow-rumped warbler, the heart lay in the neck outside of the thoracic cavity. Published reports of similar occurrences of an ectopically placed heart concern birds, cattle and humans. The fact that various species of both placental mammals and birds show evidence of heritability for heart defects, and that these species cannot interbreed, combined with the fact that birds and mammals have many similar malformations, points to either a common external causative factor or a common origin. Genes that code the malformed heart must be transmitted with that part of the genetic makeup common to all birds and mammals. Malformations caused by teratogens produce widespread organ injury to a potentially normal embryo whereas the evolutionary malformation is an organ-specific anomaly in an otherwise normal mammal or bird and occurs in widely separated species. The implications of this theory are important for parents of children with an isolated congenital heart defect who may have ingested one or another drug or chemical or have been exposed to toxins or infectious agents before or after conception of the affected offspring.

  8. Reconstruction of middle ear malformations

    Directory of Open Access Journals (Sweden)

    Schwager, Konrad

    2007-01-01

    Full Text Available Malformations of the middle ear are classified as minor and major malformations. Minor malformations appear with regular external auditory canal, tympanic membrane and aerated middle ear space. The conducting hearing loss is due to fixation or interruption of the ossicular chain. The treatment is surgical, following the rules of ossiculoplasty and stapes surgery. In major malformations (congenital aural atresia there is no external auditory canal and a deformed or missing pinna. The mastoid and the middle ear space may be underdevelopped, the ossicular chain is dysplastic. Surgical therapy is possible in patients with good aeration of the temporal bone, existing windows, a near normal positioned facial nerve and a mobile ossicular chain. Plastic and reconstructive surgery of the pinna should proceed the reconstruction of the external auditory canal and middle ear. In cases of good prognosis unilateral aural atresia can be approached already in childhood. In patients with high risk of surgical failure, bone anchored hearing aids are the treatment of choice. Recent reports of implantable hearing devices may be discussed as an alternative treatment for selected patients.

    International Nuclear Information System (INIS)

    The paper reviews congenital malformations in humans and presents possible causes. 60% of all malformations are a result of environmental and other factors; i.e. not hereditary or caused by a disease of the mother. The teratogenic effects of ionizing radiation, drugs, alcohol, polyvinyl chloride and trichlorophenol are discussed as well as the effect of the mother's working in certain fields, e.g. clinical laboratories or printing offices; in the latter case the teratogenic noxae are still unknown. Efficient research requires centralized storage of all data on children born with malformations and on the mother's health situation during pregnancy, and the legislator is asked to do so while observing the law on data protection. Foundation of a German Institute of Teratology is recommended. In order to intensify research, it is suggested to set up groups or departments for research on malformations in some major paediatric hospitals. (MG)

    2015-01-01

    Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity. PMID:26734559

  13. No skeletal dysplasia in the Nariokotome boy KNM-WT 15000 (Homo erectus)--a reassessment of congenital pathologies of the vertebral column.

    Science.gov (United States)

    Schiess, Regula; Haeusler, Martin

    2013-03-01

    The Nariokotome boy skeleton KNM-WT 15000 is the most complete Homo erectus fossil and therefore is key for understanding human evolution. Nevertheless, since Latimer and Ohman (2001) reported on severe congenital pathology in KNM-WT 15000, it is questionable whether this skeleton can still be used as reference for Homo erectus skeletal biology. The asserted pathologies include platyspondylic and diminutive vertebrae implying a disproportionately short stature; spina bifida; condylus tertius; spinal stenosis; and scoliosis. Based on this symptom complex, the differential diagnosis of spondyloepiphyseal dysplasia tarda, an extremely rare form of skeletal dysplasia, has been proposed. Yet, our reanalysis of these pathologies shows that the shape of the KNM-WT 15000 vertebrae matches that of normal modern human adolescents. The vertebrae are not abnormally flat, show no endplate irregularities, and thus are not platyspondylic. As this is the hallmark of spondyloepiphyseal dysplasia tarda and related forms of skeletal dysplasia, the absence of platyspondyly refutes axial dysplasia and disproportionate dwarfism. Furthermore, we neither found evidence for spina bifida occulta nor manifesta, whereas the condylus tertius, a developmental anomaly of the cranial base, is not related to skeletal dysplasias. Other fossils indicate that the relatively small size of the vertebrae and the narrow spinal canal are characteristics of early hominins rather than congenital pathologies. Except for the recently described signs of traumatic lumbar disc herniation, the Nariokotome boy fossil therefore seems to belong to a normal Homo erectus youth without pathologies of the axial skeleton.

  14. Three-dimensional computed tomography in the assessment of congenital scoliosis

    International Nuclear Information System (INIS)

    Objective. Patients with congenital vertebral anomalies frequently are afflicted with kyphoscoliosis, with the curvatures often being severe and progressive. Spinal fusion almost always is the treatment of choice in such patients. This report examines the use of three-dimensional computed tomography (3D CT) in the preoperative investigation of patients with congenital scoliosis.Design and patients. Twelve spinal CT examinations on 11 pediatric patients with congenital scoliosis underwent image processing to produce 3D images. The 3D images were compared with both the axial sections from the CT examinations and multiplanar reformations with regard to the detection of malformations liable to cause progression of scoliosis (i. e., hemivertebrae and unsegmented bars).Results and conclusions. In six of the 12 cases, the 3D images provided improved depiction of the congenital anomalies and their interrelationships compared with planar CT images. This work suggests that 3D CT can be a useful tool in the assessment of patients with congenital scoliosis. (orig.)

    Follicular atrophoderma has always been associated with other congenital malformations including, Conradi-Hnermann syndrome, Bazex's syndrome and keratosis palmaris et plantaris dissipata. Congenital pseudarthrosis of the tibia has usually been associated with neurofibromatosis. We report a case of follicular atrophoderma in association with congenital pseudarthrosis of the tibia: a previously unreported association with, in our case, a good outcome for the pseudarthrosis.

    Full Text Available BB Lee,1 I Baumgartner21Department of Surgery, George Washington University, Washington, DC, USA; 2Swiss Cardiovascular Center, University Hospital Bern, Bern, SwitzerlandAbstract: Venous malformation is a congenital vascular malformation resulting from defective development during various stages of embryogenesis and selectively affecting the venous system. Depending on the embryologic stage when the developmental arrest occurred, the clinical presentation of venous malformation is extremely variable in location, extent, severity, natural progression, and hemodynamic impact. Extratruncular lesions occur in the earlier stages of embryonic life, and retain characteristics unique to mesenchymal cells (angioblasts, growing and proliferating when stimulated internally (eg, by menarche, pregnancy, and hormones or externally (eg, by trauma or surgery. These lesions also have a significant hemodynamic impact on the venous system involved, in addition to the risk of localized intravascular coagulopathy. However, truncal lesions, as defective developments along the late stage, no longer carry the risk of proliferation and recurrence due to lack of mesenchymal characteristics. Although, they often have serious hemodynamic consequences due to direct involvement of the main vein trunk. Therefore, a thorough clinical history and careful physical examination should be followed by an appropriate combination of noninvasive and less invasive tests (eg, Doppler ultrasonography, magnetic resonance imaging, computed tomography to confirm the clinical impression as well as to define the extent and severity of the venous malformation. Invasive tests, eg, phlebography or angiography, are seldom needed for the diagnosis per se. Additional evaluation for coagulation abnormalities, eg, D-dimer and fibrinogen levels, is generally recommended, especially for the treatment of surgery and endovascular candidates with extensive lesions to assess the localized intravascular coagulopathy status. Localized intravascular coagulopathy may cause serious thrombohemorrhagic events, including deep venous thrombosis and pulmonary embolism.Keywords: venous malformation, extratruncular lesions, truncal lesions, noninvasive tests, less invasive tests, localized intravascular coagulopathy

    Congenital diverticulum of the heart is an unusual malformation. It is frequently associated with thoracic or abdominal midline alterations and also with various types of congenital heart disease. Complications of this anomaly are rupture, peripheral embolism and heart failure. Surgical management consists of resection of the diverticulum either as an isolated operation or at the time of correction of accompanying malformations. We present six cases of congenital diverticulum of the heart, four on the right ventricle and two on the left. In one patient with Fallot's tetralogy a diverticulum was found at necropsy; in two cases the underlying malformation was double outlet ventricle; one case had pulmonary artery stenosis and two did not have associated malformations.

OBJECTIVE: Verify frequency and types of abdominal abnormalities detected in children with and without CHD through abdominal ultrasound (AUS, compare the patients in relation to their dysmorphic/cytogenetic findings and perform an estimative of the cost-effectiveness of the screening through AUS. METHODS: We conducted a cross-sectional study with a control cohort.

All patients with CHD underwent AUS, high-resolution karyotype and fluorescence in situ hybridization (FISH for microdeletion 22q11.2. RESULTS: AUS identified clinically significant abnormalities in 12.2% of the cases and 5.2% of controls (p= 0.009, with a power of significance of 76.6%. Most malformations with clinical significance were renal anomalies (10.4% in cases and 4.9% in controls; p= 0.034. In Brazil, the cost of an AUS examination for the Unified Health System is US$ 21. Since clinically significant abnormalities were observed in one in every 8.2 CHD patients, the cost to identify an affected child was calculated as approximately US$ 176. CONCLUSION: Patients with CHD present a significant frequency of abdominal abnormalities detected by AUS, an inexpensive and noninvasive diagnostic method with good sensitivity. The cost of screening for these defects is considerably lower than the cost to treat the complications of late diagnoses of abdominal malformations such as renal disease.

    US is a noninvasive modality that has proved highly valuable in the assessment of congenital intracranial anomalies in the neonate. The patterns of malformation must be familiar to those who obtain and interpret neonatal cranial sonograms. The authors present a variety of cases of congenital anomalies studied with US, including agenesis of the corpus callosum, Dandy-Walker malformation, occipital enecphalocele, congenital hydrocephalus, vein of Galen aneurysm, hydranencephaly, holoprosencephaly, absence of the septum pellucidum, schizencephaly, and hypoplastic cerebellum.

    Pregnant albino rats were irradiated of with Cobalt-60 gamma rays on twelfth day of gestation (corresponding to major organogenesis), with 0.5, 1, 2 and 3 Gy.The changes observed at full term included numbers of absorption sites and fetuses. Measurements of fetal size, weight, lateral length, girth, tail length and antroposterior and lateral diameters of skull. Results revealed that number of absorption sites significantly increased with the dose of 3 Gy and the number of litters showed significant decrease with doses of 2 and 3 Gy. Fetal measurements were significantly decreased with 2 and 3 Gy. This reflects high radiosensitivity of the embryo to radiation particularly during stage of organogenesis

Duplication of the ureter may be complete or incomplete. Incomplete duplication of ureter is well known as bifid ureter. Presence of various anomalies of the ureter is associated with increased risk of urinary tract infections and many other clinical complications. PMID:26286110

    Full Text Available Abstract Anorectal malformations comprise a wide spectrum of diseases, which can affect boys and girls, and involve the distal anus and rectum as well as the urinary and genital tracts. They occur in approximately 1 in 5000 live births. Defects range from the very minor and easily treated with an excellent functional prognosis, to those that are complex, difficult to manage, are often associated with other anomalies, and have a poor functional prognosis. The surgical approach to repairing these defects changed dramatically in 1980 with the introduction of the posterior sagittal approach, which allowed surgeons to view the anatomy of these defects clearly, to repair them under direct vision, and to learn about the complex anatomic arrangement of the junction of rectum and genitourinary tract. Better imaging techniques, and a better knowledge of the anatomy and physiology of the pelvic structures at birth have refined diagnosis and initial management, and the analysis of large series of patients allows better prediction of associated anomalies and functional prognosis. The main concerns for the surgeon in correcting these anomalies are bowel control, urinary control, and sexual function. With early diagnosis, management of associated anomalies and efficient meticulous surgical repair, patients have the best chance for a good functional outcome. Fecal and urinary incontinence can occur even with an excellent anatomic repair, due mainly to associated problems such as a poorly developed sacrum, deficient nerve supply, and spinal cord anomalies. For these patients, an effective bowel management program, including enema and dietary restrictions has been devised to improve their quality of life.

    Full Text Available Background: The urogenital congenital malformations represent the first place within the genetic malformations in the province of Las Tunas.Objective: To characterize the renal congenital malformations in pediatric patients of the herein mentioned province, from 2010 to 2014.Methods: A descriptive study was carried out with 283 paediatric patients with renal and urinary tract congenital malformation, in the province and period herein stated. The variables included: sex, clinical manifestations, more frequent malformations, which of them needed surgical treatment, the positive results of the radiological studies, and the malformations that developed into chronic renal failure. The data were analyzed according to descriptive statistics.Results: The male sex represented a 63,96 %. A 57,95 % of the children were asymptomatic. Within the congenital malformations ectasia prevailed with a 49,47 %. 100 % of the cases with a compromise of the ureteovesiccal union, ureterocele and shell of the posterior urethra, 78 % of the patients with stenosis of the ureteropyelic union and 4,76 % of the patients with vesicoureteric reflux needed surgical treatment. The radiological studies were highly positive. 1,41 % of the patients developed chronic renal failure.Conclusions: Most of the patients with renal and urinary tract congenital malformations were diagnosed before the 5 years of age. Only four patients developed chronic renal failure.

    Anomalous vertebral artery (VA), commonly the persistent first intersegmental artery (FIA) is often seen with congenital atlantoaxial dislocations (AAD). An unusual redundant/ectatic loop of VA passing below the C1 (upside down VA) has been described below and appears to be different from FIA. The operative technique to protect it while C1-2 joint manipulation has been described. A 35 year old male presented with progressive spastic quadriparesis after trivial trauma. Radiology showed irreducible atlantoaxial dislocation with occipitalised C1 and C2-3 fusion. The left VA was anomalous passing beneath the C1 arch with a redundant loop lying posterior to the C1-2 joint. This was unlike the persistent first intersegmental artery (FIA) and was safeguarded while dissecting the C1-2 facet. The artery was dissected and safeguarded while performing C1-2 joint manipulation. A redundant/ectatic loop lying posterior to C1-2 joint is an unusual variant of anomalous VA. Evaluation of preoperative radiology helps in diagnosing such anomalous VA. Dissection of the entire redundant loop of the anomalous artery is important in opening the C1-2 joint required for reduction and placement of spacer/ bone grafts to achieve good bony fusion. Also mobilizing the loop allows safe insertion of lateral mass screw. Care needs to be taken while fastening screws to prevent compression of the loop. PMID:26527042

    Full Text Available BACKGROUND: A norectal malformations are relatively encountered anomalies. Presentations may vary from mild to severe and bowel control is t he main concern. AIM: To study the modes of presentation , types of anomalies , associated anomalies , reliability of clinical signs and radiological investigations in the diagnosis and the prognosis and continence in the post - operative in relation to type of anomaly and associated anomaly (s. MATERIAL AND METHODS: 50 cases of anorectal malformations admit ted to Department of Paediatric Surgery , in Medical Coll ege and Research Institute , were included in the study. Data related to the objectives of the study were collected. RESULTS: Commonest mode of presentation was failure to pass meconium 50%. 59% of mal es had high anomalies , while 53% females had intermediate anomalies. The diagnosis of low anomaly was made clinically , while high and intermediate anomalies needed further investigations. Associated anomalies were noted in 46.6% of the cases. 71.42% of the se patients had either a high or intermediate ARM. All patients with high anomalies underwent a 3 stage procedure , while low anomalies underwent a single stage procedure followed by anal dilatations. Rectal mucosal prolapse (2 cases , wound infection (4 ca ses , stenosis (3 cases , retraction of neo anus (1 case was seen. All the patients with low anomalies had a good functional result post operatively , while 57% and 28% of patients with intermediate and high anomalies had good results. CONCLUSION : Anorectal malformations are common congenital anomalies. Males are more commonly affected (1.3:1. Low anomalies are the commonest lesions noted in both the sexes (36.67%. High anomalies are more frequent in males. Invertogram offer an accurate diagnosis for planning management in patients with anorectal malformations. Low anomalies have a better outcome following surgery. For intermediate and high anomalies a staged repair offers better results . The situation would improve further if MRI Imaging is more r eadily available and these children are brought for appropriate treatment at the earliest.

    Recent advances in MRI have revealed congenital brain malformations and subtle developmental abnormalities of the cerebral and cerebellar cortical architecture. Typical cerebellar cortical dysplasia as a newly categorized cerebellar malformation, has been seen in patients with Fukuyama congenital muscular dystrophy. Cerebellar cortical dysplasia occurs at the embryonic stage and is often observed in healthy newborns. It is also incidentally and initially detected in adults without symptoms. To the best of our knowledge, cerebellar dysplasia without any related disorders is very rare. We describe the MRI findings in one patient with disorganized foliation of both cerebellar hemispheres without a related disorder or syndrome

  13. Angiographic features of rapidly involuting congenital hemangioma (RICH)

    International Nuclear Information System (INIS)

    Rapidly involuting congenital hemangioma (RICH) is a recently recognized entity in which the vascular tumor is fully developed at birth and undergoes rapid involution. Angiographic findings in two infants with congenital hemangioma are reported and compared with a more common postnatal infantile hemangioma and a congenital infantile fibrosarcoma. Congenital hemangiomas differed from infantile hemangiomas angiographically by inhomogeneous parenchymal staining, large and irregular feeding arteries in disorganized patterns, arterial aneurysms, direct arteriovenous shunts, and intravascular thrombi. Both infants had clinical evidence of a high-output cardiac failure and intralesional bleeding. This congenital high-flow vascular tumor is difficult to distinguish angiographically from arteriovenous malformation and congenital infantile fibrosarcoma. (orig.)

    Background: venous malformations are congenital lesions that can cause pain, decreased range of movement, compression on adjacent structures, bleeding, consumptive coagulopathy and cosmetic deformity. Sclerotherapy alone or combined with surgical excision is the accepted treatment in symptomatic malformations after failed treatment attempts with tailored compression garments. Objectives: to report our experience with percutaneous sclerotherapy of peripheral venous malformations with ethanol 96%. Patients and methods: 41 sclerotherapy sessions were performed on 21 patients, aged 4-46 years, 15 females and 6 males. Fourteen patients were treated for painful extremity lesions, while five others with face and neck lesions and two with giant chest malformations had treatment for esthetic reasons. All patients had a pre-procedure magnetic resonance imaging (MRI) study. In all patients, 96% ethanol was used as the sclerosant by direct injection using general anesthesia. A minimum of 1-year clinical follow-up was performed. Follow-up imaging studies were performed if clinically indicated. Results: 17 patients showed complete or partial symptomatic improvement after one to nine therapeutic sessions. Four patients with lower extremity lesions continue to suffer from pain and they are considered as a treatment failure. Complications were encountered in five patients, including acute pulmonary hypertension with cardiovascular collapse, pulmonary embolus, skin ulcers (two) and skin blisters. All patients fully recovered. Conclusion: sclerotherapy with 96% ethanol for venous malformations was found to be effective for symptomatic improvement, but serious complications can occur.

    Two children developed hepatoblastoma concurrent with congenital portosystemic shunts (PSSs) (Abernethy malformations). Both underwent operative ligation of their PSSs. One received concurrent tumor resection, whereas the other was deemed initially unresectable and underwent biopsy followed by neoadjuvant chemotherapy. Although benign hepatic masses, such as focal nodular hyperplasia and nodular regenerative hyperplasia, are common in patients with Abernethy malformations, malignant tumors have also been documented and should always be considered in the differential diagnosis of a patient with a congenital PSS and a hepatic mass.

  20. 16 multi-slice CT three-dimensional and multiplanar reconstruction for evaluation of pediatric congenital scoliosis

    International Nuclear Information System (INIS)

    Objective: Our study is to use of 16 MSCT three-dimensional images and multiplanar reconstruction images in the preoperative investigation of patients with congenital scoliosis, to study its technical advantage and work out surgical plan. Methods: Twenty-seven pediatric patients with congenital scoliosis processing between April to October 2004 were reviewed, including 13 boys and 14 girls. X-ray plain film and sixteen multi-slice CT examination on curved/standard multiplanar reconstruction and three- dimensional computed tomographic imaging may offer, many potential advantages for defining congenital spine anomalies liable to cause progression of scoliosis, including visualization of the deformity in any plane, from any angle, with the overlying structures subtracted. Results: Ten patients had segmentation defects, 6 patients underwent formation defects, 11 patients had complex, unclassifiable anomalies. The patients of rib deformity were found in 15 patients, the most prominent part of the rib cage deformity was at the same level as the most rotated vertebra in 7 patients; 8 patients had vertebral anomalies accompanied with diastematomyelie, including 6 patients with uncompleted or completed bony spur. In 19 of 27 cases, the muhiplanar reconstruction and three-dimensional images allowed identification of unrecognized malformations and completely evaluated the degree of scoliosis, during conventional X-ray images and axial CT images, including volume 3D imaging evaluated approximately classification and modality of complex anomalies in 11 cases, which were unclassifiable malformation in 7 cases and unsegmented bar with contralateral hemivertebrae; 4 children had segmentation defects revealed unilateral unsegmented bar (3 cases) and bilateral block vertebra (1 case) in volume 3D reconstruction images; 2 children were found occultation hemivertebrae which were not been discovered during conventional X-ray images and axial CT images; and 2 children were revaluated the amount of hemivertebrae. The curved multiplanar reconstruction images in all eases were best for defining the spinal canal and spinal medulla, and showed clearly the modality and developed way of bony spur, even the relationship with spinal cord in 6 cases. The standard muhiplanar reformatted images in 4 cases were helpful in showing occipital-C1-C2 anatomy and malformation, especially the junction of skull and cervix malformation. Conclusion: Our data suggest that 16 MSCT three- dimensional images and muhiplanar reconstruction images appears to be most useful tool in the patients with congenital scoliosis in which the anomalies are complex, multiple, or obscured by deformity and rib malformation. The reformatted images of MSCT is markedly superior to conventional X-ray images and axial CT images when used to evaluate the progressive spinal curvatures and work out surgical plan. (authors)

    Full Text Available Objective To investigate the imaging and clinicopathological features of pachygyria limited in the right temporo-parieto-occipital lobe and the key points of its diagnosis and treatment, in order to improve the recognition of this disease.  Methods and Results A 2-year-old boy was admitted to hospital because of paroxysmal loss of consciousness and convulsion for 18 months with progressive aggravation. MRI showed malformations of cortical development in the right temporo-parieto-occipital lobe. Epileptic foci resection on the right temporo-parieto-occipital lobe was made. Histological examination after operation showed uneven thickening of gray matter, shrinking of white matter and disappearing cortical stratification, while a lot of dysmorphic neurons, balloon cells and scattered balloon cells in white matter appeared. Immunohistochemical staining revealed that dysmorphic neurons were positive for non-phosphorylated neurofilament protein SMI-32, microtubule-associated protein-2 (MAP-2 and vimentin (Vim or neurofilament protein (NF. Both dysmorphic neurons and balloon cells expressed phosphorylated ribosomal S6 protein (RPS6, while the former was stronger than the latter. Balloon cells were not positive for MAP-2 or Vim. No disturbance of consciousness or limb twitches occurred in this patient during one-year follow-up.  Conclusions Congenital pachygyria was cortical dysplasia caused by the early proliferation and migration disorder of brain, and should be distinguished with focal cortical dysplasia (FCD type Ⅱ b and tuberous sclerosis complex (TSC. Clinical history, imaging and histological features should be included in the diagnosis. DOI: 10.3969/j.issn.1672-6731.2016.02.005

    Full Text Available ABSTRACT: OBJECTIVE: To study the incidence of congenital malformation, to diagnose congenital malformations by USG in antenatal period as early as possible and to find out the cause and associated factors affecting congenital malformation. MATERIALS AND METHODS: The present study was conducted for one year in the department of obstetrics and Gynaecology, Rajindra Hospital Patiala. All cases whether detected antenatally or at the time of birth were taken. The diagnosis was made by USG in antenatal cases and at the time of delivery in those cases who have no previous USG reports or antenatal checkups . RESULTS: There were total 900 deliveries, out of which 831 were live born and 69 were still born. Congenital malformations were present in 62 cases out of which 23 were live born, 29 were still births and the re were 10 cases of abortion. The overall incidence of congenital malformations in the present study was 68.89/1000 births (6.889%. Out of total 62 cases of congenital malformations, CNS malformations were found to be the most common (66.13%, followed by musculoskeletal system (24.19% . In the present study USG was found to be a good method of screening of congenital malformations with high specificity (100% and sensitivity (73.21%. The PPV was 100% and NPV was 98.01%. The percentage of false positive re sults was 0% but that of false negative was 26.78%. CONCLUSION: Ignorance, illiteracy and unawareness about the availability of USG, lack of adequate antenatal checkups is the main cause of late diagnosis of congenital malformations. Best effort should be put in to make the diagnosis of congenital malformations early so that referral can be made at the earliest for early intervention and planned delivery at an appropriate center.

    Full Text Available Anorectal malformations are the congenital condition, seen in approximately 1 in 5000 live births. It affects male and female in the ratio of 1.3:1. Anorectal malformations include a wide range of malformations, that not only involves the anus and rectum, but it also involves urinary and genital tract. Aims and objectives of the study, was to understand the structures involved in anorectal malformations by histological study of surgically excised segments of involved part of neonatal intestine and to understand the degree and cause of possible structural impairment in different segments of involved parts of neonatal bowel that may help in the surgical management of anorectal malformations. Present study was conducted on surgically excised segments of fifteen cases of anorectal malformations, that have been collected from Department of Paediatrics Surgery, IMS, BHU. After that processing of the samples have been done and blocks have been prepared. Then after sectioning and staining with Hematoxyline and Eosin, findings have been noted under the microscope. Histopathological examination revealed the abnormalities of varying degrees. To conclude this study supports that the malformed segments should be excised, regarding controversial issue of preserving or excising the distal segment of anorectum for better functional outcome.

    Full Text Available Background: ECLAMC is a registry, aimed to assess the incidence of congenital malformations, that started in 1967 and Chile incorporated to it in 1969. Aim: To report the incidence of cleft lip/palate, updated to 1999 in the University of Chile Maternity Hospital and other Chilean hospitals participating in the ECLAMC. Patients and methods: A review of the ECLAMC database that registers all births or stillbirths of more than 500 g. Results: The incidence of orofacial cleft, at the University of Chile Maternity Hospital, in the period 1991-1999 was 17.8 per 10000 (12.6 for cleft lip and 5.2 for cleft palate. The incidence in the rest of participating hospitals was 12.04 and 4.6 respectively. Males had a higher incidence of cleft lip and 80% of children with cleft palate, had other malformations, most of them as part of a syndrome (13 and 18 trisomy, holoproscencephalia, Pierre Robin, Apert en EE syndromes, anencephaly etc. In three of 12 children with cleft lip but without cleft palate, there was a relative with the same malformation. Conclusions: It is proposed that both entities, cleft lip with or without cleft palate and cleft palate without cleft lip, are two etiopathogenically different conditions (Rev Méd Chile 2001; 129: 285-93.

    Forty-three patients with maxillo-nasal dysplasia have been subjected to a radiographic examination of the cervical spine. In 44.2 per cent malformations of the cervical vertebrae of a minor or major type were revealed. Dysplasia of the vertebral bodies related to persistence of the chorda dorsalis, a very rare malformation, was found in six cases. No correlation between the incidence or serverity of the malformations and the degree of malocclusion of the jaws and facial deformity, characteristic of Binder syndrome, were noted. The maxillo-nasal dysplasia and the spinal malformations probably have a common cause during the embryologic stage. (orig.)

    Congenital agenesis of the sternum is an extremely unusual malformation rarely encountered by the practicing Otolaryngologist. It typically arises in conjunction with other midline ventral congenital anomalies, including abdominal, diaphragmatic, and cardiac malformations. We report a case series of two patients managed with tracheotomy placement due to prolonged intubation. The first patient was a 63-day-old infant born at 34 weeks gestation with dysmorphic features, cleft lip and palate, and skeletal dysplasia, including absence of the sternum. The second patient was a 31-day-old infant born with ectopic cordis and diaphragmatic hernia. The inadequate closure of the anterior chest wall secondary to manubrium malformation or a variant contributes significantly to a child's inability to generate adequate ventilatory pressures. As a result, airway management must be considered not only to ensure airway patency but also an appropriate physiological environment to allow for adequate air exchange in the lungs. PMID:20015780

    Faced with a cardiac arrhythmia occuring in an apparently healthy heart, it is necessary to perform an anatomical investigation to detect any unsuspected anomalies. Congenital cardiopathy must certainly be excluded, as this is often responsible for rhythm disorders and/or cardiac conduction defects. Similarly, any acquired conditions, cardiomyopathy, or cardiac tumour must be sought. However, the possibility should always be considered of a minimal congenital malformation, which could be repsonsible for: any type of cardiac arrhythmia: rhythm disorder or conduction defect at the atrial, junctional or ventricular level, with a benign or serious prognosis. Unexpected therapeutic difficulties during radiofrequency ablation procedures or at implantation of pacemakers or defibrillators. Together with rhythm studies, the investigation of choice is high quality imaging, either the classic left or right angiography or the more modern cardiac CT or intracardiac mapping. PMID:16433240

    Congenital neutropenia comprises a variety of genetically heterogeneous phenotypic traits. Molecular elucidation of the underlying genetic defects has yielded important insights into the physiology of neutrophil differentiation and function. Non-syndromic variants of congenital neutropenia are caused by mutations in ELA2, HAX1, GFI1, or WAS. Syndromic variants of congenital neutropenia may be due to mutations in genes controlling glucose metabolism (SLC37A4, G6PC3) or lysosomal function (LYST, RAB27A, ROBLD3/p14, AP3B1, VPS13B). Furthermore, defects in genes encoding ribosomal proteins (SBDS, RMRP) and mitochondrial proteins (AK2, TAZ) are associated with congenital neutropenia syndromes. Despite remarkable progress in the field, many patients with congenital neutropenia cannot yet definitively be classified by genetic terms. This review addresses diagnostic and therapeutic aspects of congenital neutropenia and covers recent molecular and pathophysiological insights of selected congenital neutropenia syndromes.

  18. Cardiac and vascular malformations

    International Nuclear Information System (INIS)

    Malformations of the heart and great vessels show a high degree of variation. There are numerous variants and defects with only few clinical manifestations and are only detected by chance, such as a persistent left superior vena cava or a partial anomalous pulmonary venous connection. Other cardiovascular malformations are manifested directly after birth and need prompt mostly surgical interventions. At this point in time echocardiography is the diagnostic modality of choice for morphological and functional characterization of malformations. Additional imaging using computed tomography (CT) or magnetic resonance imaging (MRI) is only required in a minority of cases. If so, the small anatomical structures, the physiological tachycardia and tachypnea are a challenge for imaging modalities and strategies. This review article presents the most frequent vascular, cardiac and complex cardiovascular malformations independent of the first line diagnostic imaging modality. (orig.)

  19. Congenital Pseudohorseshoe Lung Associated with Scimitar Syndrome

    International Nuclear Information System (INIS)

    Horseshoe lung is a congenital pulmonary malformation that is usually associated with scimitar syndrome. This malformation consists of fusion of both pulmonary lobes from the posterobasal segments. The fusion appears in the retrocardiac area, in front of the esophagus and thoracic aorta. Pleural separation of pulmonary lobes distinguishes pseudohorseshoe appearance from a true horseshoe lung. Scimitar syndrome known as hypogenetic lung syndrome is a part of the congenital pulmonary venolobar syndrome. It is a partial anomalous pulmonary venous return with pulmonary hypoplasia. Scimitar vein is an anomalous drainage vessel between the right pulmonary lobe vessels and the inferior vena cava. The appearance of the vessel resembles Turkish scimitar; therefore, the syndrome is called scimitar syndrome. We hereby report a 61-year-old woman with adult form congenital scimitar syndrome and will describe the imaging findings of pseudohorseshoe lung appearance

  20. MRI and MR angiography of cerebral arterio-venous malformations

    International Nuclear Information System (INIS)

    Av malformations are cerebral abnormalities with a high risk of bleeding. The role of MRI and MR angiography (MRA) for demonstrating these congenital vascular malformations has been studied. It has been shown that MRI/MRA can provide a rapid and certain diagnosis. MRA can demonstrate arteries to the second set of branches beyond the main cerebral vessels. It has the advantage of being able to produce rapidly and non-invasively 3-D images and, unlike conventional angiography, it can be repeated at will. The disadvantage is the limited spacial resolution and the difficulty in distinguishing between arteries and veins. (orig.)

  1. Imaging features of ductal plate malformations in adults

    International Nuclear Information System (INIS)

    Ductal plate malformations, also known as fibrocystic liver diseases, are a group of congenital disorders resulting from abnormal embryogenesis of the biliary ductal system. The abnormalities include choledochal cyst, Caroli's disease and Caroli's syndrome, adult autosomal dominant polycystic liver disease, and biliary hamartoma. The hepatic lesions can be associated with renal anomalies such as autosomal recessive polycystic kidney disease (ARPKD), medullary sponge kidney, and nephronophthisis. A clear knowledge of the embryology and pathogenesis of the ductal plate is central to the understanding of the characteristic imaging appearances of these complex disorders. Accurate diagnosis of ductal plate malformations is important to direct appropriate clinical management and prevent misdiagnosis.

    2005-09-01

    Full Text Available Recent studies show that assisted reproductive technologies (ART, whether in vitro fertilization (IVF or intra-cytoplasmatic sperm injection (ICSI or applied to cloning by somatic cell nuclear transfer (SCNT are associated to a higher risk of congenital malformations and errors in deprogramming, maintenance or reprogramming genomic imprinting in humans and animals. IVF and ICSI are also associated to an increased admission to neonatal intensive care units and more need for health care resources in infancy. A mutagenic effect of a chemical used in SCNT has been reported and gene depression was found in bovine embryos obtained by IVF or SCNT. The causes of these anomalies could be pathological conditions for which ART is applied, a direct effect of technologies on the zygotes or embryos, avoidance for zygotes or embryos of the oviduct path that is needed to elicit necessary immunity or genomic programming processes, or adaptive selective steps acquired during thousands of millions of generations in evolution. The knowledge of evolution is emphasized as essential in the scientific ethical analysis (Rev Méd Chile 2005; 133: 1075-80.

Our findings were compared with a total of nine patients identified from previous publications in the world literature. The histologic findings in our cases was re-reviewed for diagnosis and specifically for features of calcification and secondary aneurysmal bone cyst (ABC). Clinical follow-up was requested from referring institutions. Nine of 856 chondroblastomas arose in vertebrae (incidence 1.4%; thoracic 5, lumbar 1, cervical 2, sacral 1). There were six males and three females ranging in age from 5 to 41 years (mean 28 years). Satisfactory imaging from seven patients revealed the tumor to arise from the posterior elements in four and the body in three. All tumors were expansive, six of seven were aggressive, and the spinal canal was significantly narrowed by bone or soft tissue mass in six. In one patient canal invasion was minimal. Calcification was pronounced in two and subtle in four. The sole nonaggressive-appearing tumor was heavily mineralized. Bony edema and secondary ABC were not seen on MR imaging. None of the cases had microscopic features of significant secondary ABC. Calcification, and specifically ''chicken wire'' calcification, was identified in two patients. Pulmonary metastases occurred in none. Vertebral chondroblastoma is a rare neoplasm that presents later in life than its appendicular counterpart. On imaging it is aggressive in appearance with bone destruction, soft tissue mass, and spinal canal invasion. The lesions contain variable amounts of mineral. Secondary aneurysmal cyst bone formation was not a feature in our study group. (orig.)

  6. Building the Vertebrate Spine

    Pourqui, Olivier

    2008-03-01

    The vertebrate body can be subdivided along the antero-posterior (AP) axis into repeated structures called segments. This periodic pattern is established during embryogenesis by the somitogenesis process. Somites are generated in a rhythmic fashion from the paraxial mesoderm and subsequently differentiate to give rise to the vertebrae and skeletal muscles of the body. Somite formation involves an oscillator-the segmentation clock-whose periodic signal is converted into the periodic array of somite boundaries. This clock drives the dynamic expression of cyclic genes in the presomitic mesoderm and requires Notch and Wnt signaling. Microarray studies of the mouse presomitic mesoderm transcriptome reveal that the segmentation clock drives the periodic expression of a large network of cyclic genes involved in cell signaling. Mutually exclusive activation of the Notch/FGF and Wnt pathways during each cycle suggests that coordinated regulation of these three pathways underlies the clock oscillator. In humans, mutations in the genes associated to the function of this oscillator such as Dll3 or Lunatic Fringe result in abnormal segmentation of the vertebral column such as those seen in congenital scoliosis. Whereas the segmentation clock is thought to set the pace of vertebrate segmentation, the translation of this pulsation into the reiterated arrangement of segment boundaries along the AP axis involves dynamic gradients of FGF and Wnt signaling. The FGF signaling gradient is established based on an unusual mechanism involving mRNA decay which provides an efficient means to couple the spatio-temporal activation of segmentation to the posterior elongation of the embryo. Another striking aspect of somite production is the strict bilateral symmetry of the process. Retinoic acid was shown to control aspects of this coordination by buffering destabilizing effects from the embryonic left-right machinery. Defects in this embryonic program controlling vertebral symmetry might lead to scoliosis in humans. Finally, the subsequent regional differentiation of the precursors of the vertebrae is controlled by Hox genes, whose collinear expression controls both gastrulation of somite precursors and their subsequent patterning into region-specific types of structures. Therefore somite development provides an outstanding paradigm to study patterning and differentiation in vertebrate embryos.

  8. Radionuclide imaging in the diagnosis of congenital anomalies of the kidney

    International Nuclear Information System (INIS)

    Congenital malformations of the kidney are fairly common. 57 patients with various types of congenital malformations of the kidney underwent renal scintigraphy. Most of them also underwent abdominal ultrasonography and intravenous urography. Scintigraphy was found to have high sensitivity (80 to 100%) for detection of renal congenital anomalies. Ultrasonography exhibited a somewhat lower sensitivity. The sensitivity exhibited by intravenous urography was similar to scintigraphy. It is concluded that renal scintigraphy can play a key role in the diagnosis of renal congenital anomalies, and hence, along with ultrasonography, should be performed in all such cases. (author)

  13. Management of intracranial arteriovenous malformations

    International Nuclear Information System (INIS)

    Intracranial arteriovenous malformations (AVMs) are congenital lesions that can cause serious neurological deficits or even death. They can manifest as intracranial hemorrhage, epileptic seizure, or other symptoms such as headache or tinnitus. They are detected by computed tomography or magnetic resonance imaging. Recently there have been significant developments in the management of AVMs. In this paper, the authors represent an overview of the epidemiology of AVMs and the existing treatment strategies. AVMs are ideally excised by standard microsurgical techniques. The grading scale which was proposed by Spetzler and Martin is widely used to estimate the risk of direct surgery. Stereotactic radiosurgery such as that using a gamma knife is very useful for small lesions located in eloquent areas. Technological advances in endovascular surgery have provided new alternatives in the treatment of AVMs. Currently indications for embolization can be divided into presurgical embolization in large AVMs to occlude deep arterial feeding vessels and embolization before stereotactic radiosurgery to reduce the size of the nidus. Palliative embolization can be also applied for patients with large, inoperable AVMs who are suffering from progressive neurological deficits secondary to venous hypertension and/or arterial steal phenomenon.

  3. MRI characteristics and classification of peripheral vascular malformations and tumors

    International Nuclear Information System (INIS)

    Vascular malformations and tumors comprise a broad spectrum of lesions that can cause significant morbidity and even mortality in children and adults. Classification of vascular malformations into high flow and low flow has significant impact on management since the main treatment of the former is transarterial embolization and the later percutaneous sclerotherapy. Magnetic resonance imaging (MRI) is a noninvasive effective tool for imaging and classification of vascular malformations based on the presence of lobulated masses, signal voids, and hemodynamic flow characteristics. MRI also provides details about anatomic extent of the lesion, proximity to vital structures, and involvement of multiple tissue planes. The prototype of vascular tumors is infantile hemangioma with its typical involution after a proliferative phase during infancy. Hemangioma appears as a distinct intensely enhancing soft tissue mass with enlarged feeding arteries and draining veins. Less common vascular tumors include congenital hemangioma, kaposiform hemangioendothilioma, angiolipoma, angiosarcoma, and hemangiopericytoma. (orig.)

    2015-03-01

    The foot may be the site of birth defects. These abnormalities are sometimes suspected prenatally. Final diagnosis depends on clinical examination at birth. These deformations can be simple malpositions: metatarsus adductus, talipes calcaneovalgus and pes supinatus. The prognosis is excellent spontaneously or with a simple orthopedic treatment. Surgery remains outstanding. The use of a pediatric orthopedist will be considered if malposition does not relax after several weeks. Malformations (clubfoot, vertical talus and skew foot) require specialized care early. Clubfoot is characterized by an equine and varus hindfoot, an adducted and supine forefoot, not reducible. Vertical talus combines equine hindfoot and dorsiflexion of the forefoot, which is performed in the midfoot instead of the ankle. Skew foot is suspected when a metatarsus adductus is resistant to conservative treatment. Early treatment is primarily orthopedic at birth. Surgical treatment begins to be considered after walking age. Keep in mind that an abnormality of the foot may be associated with other conditions: malposition with congenital hip, malformations with syndromes, neurological and genetic abnormalities.

    Brain vascular malformations are dynamic disorders. Although mostly considered to be of congenital origin, the improvement of clinical imaging and vasculogenesis knowledge has shown that they might also result from a biological dysfunction of the remodeling process after birth. Venous occlusive disease and ishemia may represent powerful revealing triggers and support the capillary venous origin of some vascular malformations. We report a unique case of the development of multiple de novo vascular malformations (transverse sinus dural fistula and posterior fossa cavernomas) following acoustic neuroma surgery. (orig.)

    Intracranial lipomas are rare congenital malformations. The most common type of intracranial lipoma is the interhemispheric lipoma, which is frequently associated with callosal anomalies such as hypogenesis or agenesis of the corpus callosum. In contrast, interhemispheric lipomas are less often accompanied with malformations of cortical development (MCD). We report magnetic resonance imaging findings of three infants with an interhemispheric lipoma, associated with a callosal anomaly, and MCD: two infants with nodular interhemispheric lipoma, agenesis of the corpus callosum, and polymicrogyria, and one infant with interhemispheric curvilinear lipoma, hypoplasia of the corpus callosum, and heterotopias. An association was suggested regarding the occurrence of these malformations. PMID:26808679

Fueron descartados 144 casos que no cumplían los criterios de inclusión. Las anomalías encontradas se clasificaron sobre la base del sistema anatómico mayor afectado. Se comparó la información obtenida del examen sonográfico y el anatomopatológico, con el objetivo de establecer la relación entre el diagnóstico prenatal por ultrasonido y el estudio necrópsico. La coincidencia diagnóstica entre ambos métodos de estudio fue del 82,41 %. El grupo de malformaciones encontrado con mayor frecuencia en las necropsias, fueron las cerebroespinales, con un 30,99 %, de las cuales el 13,61 % eran defectos del tubo neural. En este grupo, el 100 % de las anencefalias se diagnosticó sonográficamente y el 73 % de las espinas bífidas. Evaluando posteriormente a partir del examen ultrasonográfico, se encontraron 199 casos con diagnóstico de una malformación específica y el sistema mayormente afectado, fue el cerebroespinal (34,14 %. De estos diagnósticos positivos, 133 casos revelaron hallazgos necrópsicos idénticos (81,1 %, y fueron las anomalías cerebroespinales y las cardiovasculares las que mostraron mayor exactitud diagnóstica. En 31 casos se describieron hallazgos adicionales, para un 18,9 % y de ellos, 54,83 % tuvieron significado clínico. El diagnóstico prenatal se realizó antes de las 26 semanas de gestación en el 81,4 % y en el 18,6 %, después que la paciente sobrepasó las 26 semanas.This is a retrospective study of 358 necropsies of stilbirths and newborns, performed at the Pathological Department of the “Ramón González Coro” Hospital, in Havana, between 1996 and 2004.

    Full Text Available Background:Congenital pouch colon, also known as congenital short colon or "Pouch colon syndrome", is a rare condition that occurs in association with anorectal malformations; colon is either partially or completely replaced by pouch-like dilatation and communicates with the urogenital tract by means of a fistula. This anomaly is exclusively seen in Northern parts of India with only a few cases reported from elsewhere. Case Presentation:A 1-day old neonate was presented with abdominal distension due to lack of passage of meconium. Clinical and radiological investigations revealed ano-rectal malformation. Incidental findings were left sided renal agenesis and right sided anorchia. Laparotomy revealed congenital pouch colon which was dealt accordingly. The baby is now healthy and awaiting further reconstructive surgery. Conclusion:Although urogenital anomalies are not uncommon with congenital pouch colon, the finding of renal agenesis with unilateral anorchia is quite rare.

    Full Text Available Abstract Congenital arhinia is an extremely rare anomaly consisting of an absence of external nasal structures and nasal passages. Fewer than 30 cases have been reported. Patients with a familial absence of the nose have been reported, but the effects of genetic and maternal factors are unknown. Midface hypoplasia may accompany arhinia. Accompanying malformations are thought to be caused by an absent or rudimentary nose. A patient with partial congenital arhinia is presented and the embryology and literature review are discussed.

  1. The role of MRI in suspected inner ear malformations

    International Nuclear Information System (INIS)

    Purpose: This is a prospective analysis of the value of MRI in suspected inner ear malformations. Materials and Methods: In 50 patients (43 children and young adults, 7 adults) with suspected inner ear malformation MRI (1.5 T) was performed. In addition, 42 of these patients underwent CT. For the analysis of the inner ear structures, the constructive interference in steady state (CISS) sequence with 0.7 mm slice thickness was used. Functional tests revealed a sensorineural hearing loss or deafness in 82 temporal bones (TB) and a combined hearing loss in 4 TB. The hearing loss was unilateral in 14 patients. MRI and CT findings were compared. Results: Imaging findings were normal in 58 TB. The pathological findings included inner ear malformations (35 TB), inflammatory changes (4 TB), partial obliteration of labyrinth (2 TB) and congenital aural atresia (1 TB). An isolated absence of the cochlear nerve (1 TB) could only be found by MRI. In the remaining cases, an inner ear malformation was diagnosed by MRI and CT with the same confidence but MRI was superior in displaying the fine details. Conclusions: MRI will become the method of choice in the diagnosis of inner ear malformations. (orig.)

    Full Text Available Horseshoe lung is a congenital pulmonary malformation that is usually associated withscimitar syndrome. This malformation consists of fusion of both pulmonary lobes fromthe posterobasal segments. The fusion appears in the retrocardiac area, in front of theesophagus and thoracic aorta. Pleural separation of pulmonary lobes distinguishes pseudohorseshoeappearance from a true horseshoe lung. Scimitar syndrome known as hypogeneticlung syndrome is a part of the congenital pulmonary venolobar syndrome. It is apartial anomalous pulmonary venous return with pulmonary hypoplasia. Scimitar veinis an anomalous drainage vessel between the right pulmonary lobe vessels and the inferiorvena cava. The appearance of the vessel resembles Turkish scimitar; therefore, the syndromeis called scimitar syndrome. We hereby report a 61-year-old woman with adult formcongenital scimitar syndrome and will describe the imaging findings of pseudohorseshoelung appearance.

    Congenital bone anomalies are occasionally located adjacent to deep lipomas. These bone dysplasias may take the form of localized overgrowth or osseous malformation. Two patients wiht iliac anomalies and spinal dysraphism and one with a hypertrophied rib and vertebra associated with lipomas are described. As both the lipomas and osseous anomalies tend to lie in the same sensory nerve distribution, there may be a common embryonic neural dysfunction affecting formation and subsequent growth of these structures.

  12. Congenital tumors of the central nervous system

    International Nuclear Information System (INIS)

    Congenital tumors of the central nervous system (CNS) are often arbitrarily divided into ''definitely congenital'' (present or producing symptoms at birth), ''probably congenital'' (present or producing symptoms within the first week of life), and ''possibly congenital'' (present or producing symptoms within the first 6 months of life). They represent less than 2% of all childhood brain tumors. The clinical features of newborns include an enlarged head circumference, associated hydrocephalus, and asymmetric skull growth. At birth, a large head or a tense fontanel is the presenting sign in up to 85% of patients. Neurological symptoms as initial symptoms are comparatively rare. The prenatal diagnosis of congenital CNS tumors, while based on ultrasonography, has significantly benefited from the introduction of prenatal magnetic resonance imaging studies. Teratomas constitute about one third to one half of these tumors and are the most common neonatal brain tumor. They are often immature because of primitive neural elements and, rarely, a component of mixed malignant germ cell tumors. Other tumors include astrocytomas, choroid plexus papilloma, primitive neuroectodermal tumors, atypical teratoid/rhabdoid tumors, and medulloblastomas. Less common histologies include craniopharyngiomas and ependymomas. There is a strong predilection for supratentorial locations, different from tumors of infants and children. Differential diagnoses include spontaneous intracranial hemorrhage that can occur in the presence of coagulation factor deficiency or underlying vascular malformations, and congenital brain malformations, especially giant heterotopia. The prognosis for patients with congenital tumors is generally poor, usually because of the massive size of the tumor. However, tumors can be resected successfully if they are small and favorably located. The most favorable outcomes are achieved with choroid plexus tumors, where aggressive surgical treatment leads to disease-free survival. (orig.)

  19. Congenital intracerebral teratoma: a rare differential diagnosis in newborn hydrocephalus

    International Nuclear Information System (INIS)

    Cogenital hydrocephalus is caused by a broad spectrum of underlying disorders. In the majority of cases it is due to aqueductal stenosis and other distinct congenital anomalies, like Arnold-Chiari malformation. Nevertheless, in the differential diagnosis rare conditions such as cerebral malignancies must also be considered. We present two cases of congenital intracerebral teratoma as a differential diagnosis in congenital obstructive hydrocephalus. A teratoma is suggested when a rapidly growing hydrocephalus with a central calcified and vascularized mass is found sonographically. Regular cerebral structures using cannot be detected. Early diagnosis in such cases is of clinical importance as the prognosis of congential intracerebral teratoma is generally very poor. (orig.)

  20. Leaping lopsided: a review of the current hypotheses regarding etiologies of limb malformations in frogs

    Science.gov (United States)

    Loeffler, I.K.; Stocum, D.L.; Fallon, J.F.; Meteyer, C.U.

    2001-01-01

    Recent progress in the investigation of limb malformations in free-living frogs has underlined the wide range in the types of limb malformations and the apparent spatiotemporal clustering of their occurrence. Here, we review the current understanding of normal and abnormal vertebrate limb development and regeneration and discuss some of the molecular events that may bring about limb malformation. Consideration of the differences between limb development and regeneration in amphibians has led us to the hypothesis that some of the observed limb malformations come about through misdirected regeneration. We report the results of a pilot study that supports this hypothesis. In this study, the distal aspect of the right hindlimb buds of X. laevis tadpoles was amputated at the pre-foot paddle stage. The tadpoles were raised in water from a pond in Minnesota at which 7% of surveyed newly metamorphosed feral frogs had malformations. Six percent (6 of 100) of the right limbs of the tadpoles raised in pond water developed abnormally. One truncated right limb was the only malformation in the control group, which was raised in dechlorinated municipal water. All unamputated limbs developed normally in both groups. Three major factors under consideration for effecting the limb malformations are discussed. These factors include environmental chemicals (primarily agrichemicals), encysted larvae (metacercariae) of trematode parasites, and increased levels of ultraviolet light. Emphasis is placed on the necessary intersection of environmental stressors and developmental events to bring about the specific malformations that are observed in free-living frog populations.
