    Arthrogryposis multiplex congenita is a heterogeneous group of disorders characterized by multiple contractures with an estimated frequency of 1 in 3,000 births. With improving diagnostic methods, increasing numbers of fetuses with arthrogryposis are found. The pathogenetic mechanisms are relatively well known but the epidemiology and genetics of the prenatally lethal forms of arthrogryposis are less well known. In this study we collected all cases of a multiple contractures diagnosed in Finland during 1987-2002 including live born infants, stillbirths, and terminated pregnancies. Ninety-two cases of 214 suffered intrauterine demise (68 selective pregnancy terminations and 24 stillbirths) and 58 died in infancy. In 141 out of these cases the diagnosis could be included within lethal arthrogryposes, with a prevalence of 1 in 6,985 (1.43/10,000) births. Of these, 59 had spinal cord pathology at autopsy and thus were of neurogenic origin. Thirty-nine cases had lethal congenital contracture syndrome (LCCS) clinically characterized by total immobility of the fetus at all ultrasound examinations (12 weeks or later), multiple joint contractures in both upper and lower limbs, hydrops, and fetal death before the 32nd week of pregnancy. LCCS is noted as a unique Finnish disorder with a prevalence of 1 in 25,250 (0.40/10,000) births and is a major cause of lethal arthrogryposis in Finland.

    Differentiating proliferative nodules (PNs) from melanomas arising in congenital nevi (CN) is a considerable challenge for dermatopathologists. Most of the specimens dermatopathologists assess that deal with this differential diagnosis involve proliferations of melanocytes arising in the dermis. In this study, we compare the clinical, histologic, and molecular findings of these 2 conditions. In our database, we found 22 examples of PNs arising in the dermis of CN and 2 cases of lethal melanomas arising from the dermis/epidermis of CN of children. Importantly, we found that among dermal melanocytic proliferations arising from CN in children, PNs are far more common than lethal melanomas. Clinically, multiplicity of lesions favored a diagnosis of PNs, whereas ulceration was infrequent in PNs compared with lethal melanomas. Histologically, PNs showed several distinct patterns including expansile nodules of epithelioid melanocytes with mitotic counts lower than that seen in the melanomas (1.67 vs. 12.5 mitoses/mm), a small round blue cell pattern often highly mitotically active, neurocristic-like, blue nevus-like, a nevoid melanoma-like pattern, or an undifferentiated spindle cell pattern. The lethal melanomas both featured expansile nodules of epithelioid melanocytes with high mitotic counts (range, 5 to 20 mitoses/mm) and an ulcerated overlying epidermis. At the molecular level, the PNs showed mostly whole chromosomal copy number aberrations, which in some cases were accompanied by rare partial chromosomal aberrations, whereas both lethal melanomas showed highly elevated copy number aberrations involving 6p25 without gains of the long arm of chromosome 6.

    Background: LHX4 encodes a member of the LIM-homeodomain family of transcription factors that is required for normal development of the pituitary gland. To date, only incompletely penetrant heterozygous mutations in LHX4 have been described in patients with variable combined pituitary hormone deficiencies. Objective/Hypothesis: To report a unique family with a novel recessive variant in LHX4 associated with a lethal form of congenital hypopituitarism that was identified through screening a total of 97 patients. Method: We screened 97 unrelated patients with combined pituitary hormone deficiency, including 65% with an ectopic posterior pituitary, for variants in the LHX4 gene using Sanger sequencing. Control databases (1000 Genomes, dbSNP, Exome Variant Server, ExAC Browser) were consulted upon identification of variants. Results: We identified the first novel homozygous missense variant (c.377C>T, p.T126M) in two deceased male patients of Pakistani origin with severe panhypopituitarism associated with anterior pituitary aplasia and posterior pituitary ectopia. Both were born small for gestational age with a small phallus, undescended testes, and mid-facial hypoplasia. The parents' first-born child was a female with mid-facial hypoplasia (DNA was unavailable). Despite rapid commencement of hydrocortisone and T4 in the brothers, all three children died within the first week of life. The LHX4(p.T126M) variant is located within the LIM2 domain, in a highly conserved location. The absence of homozygosity for the variant in over 65 000 controls suggests that it is likely to be responsible for the phenotype. Conclusion: We report, for the first time to our knowledge, a novel homozygous mutation in LHX4 associated with a lethal phenotype, implying that recessive mutations in LHX4 may be incompatible with life.

    To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening. We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe. Significant patent foramen ovale, secundum atrial septal defect, and small ventricular septum defect were classified as minor CHDs, all others as major. Of 129 patients with CARM, 67% had mild CARM, 33% severe CARM, and 17% were additionally diagnosed with CHD. CHDs were distributed equally in patients with mild or severe CARMs. Patients with multiple congenital abnormalities were more frequently diagnosed with CHD (n = 16, 36%) than patients without multiple congenital malformations (n = 5, 9%, P = .001). Patients with CARM diagnosed with CHD using pediatric cardiac echo screening were younger than 3 months of age at diagnosis. Earlier general pediatric examinations missed 7 (50%) children with mild and 4 (50%) with severe CHDs. The severity of CARM could predict neither prevalence nor severity of CHD. More than one-half of CHDs were missed during the first physical examination. No new CHDs were found in patients older than 3 months of age at the time CARMs were diagnosed. We recommend screening all patients with CARM younger than 3 months of age for CHD at the time CARM is diagnosed. Preoperative echocardiography should be the rule in children younger than 3 months of age and with multiple congenital anomalies. Copyright © 2016 Elsevier Inc. All rights reserved.

    This study was set up to determine the long term ocular and systemic sequelae in patients with severe congenital toxoplasmosis. Cross sectional and retrospective study of 17 patients with severe congenital toxoplasmosis. In addition to chorioretinitis (100%), the most common abnormal ocular features were optic nerve atrophy (83%), visual acuity of less than 0.1 (85%), strabismus, and microphthalmos. In 50% of cases we observed iridic abnormalities and about 40% developed a cataract. Overt endocrinological disease, diagnosed in five of 15 patients, included panhypopituitarism (n = 2), gonadal failure with dwarfism (n = 1), precocious puberty with dwarfism and thyroid deficiency (n = 1), and diabetes mellitus and thyroid deficiency (n = 1). The observed endocrinological involvement was associated in all cases with obstructive hydrocephalus with a dilated third ventricle and optic nerve atrophy. The recognition of long term ocular, neurological, and endocrinological sequelae of congenital toxoplasmosis is important for medical management of these severely handicapped patients.

    Determine the prevalence of intraventricular hemorrhage in infants with moderate to severe congenital heart disease, investigate the impact of gestational age, cardiac diagnosis, and cardiac intervention on intraventricular hemorrhage, and compare intraventricular hemorrhage rates in preterm infants with and without congenital heart disease. A single-center retrospective review. A tertiary care children's hospital. All infants admitted to St. Louis Children's Hospital from 2007 to 2012 with moderate to severe congenital heart disease requiring cardiac intervention in the first 90 days of life and all preterm infants without congenital heart disease or congenital anomalies/known genetic diagnoses admitted during the same time period. None. Cranial ultrasound data were reviewed for presence/severity of intraventricular hemorrhage. Head CT and brain MRI data were also reviewed in the congenital heart disease infants. Univariate analyses were undertaken to determine associations with intraventricular hemorrhage, and a final multivariate logistic regression model was performed. There were 339 infants with congenital heart disease who met inclusion criteria and 25.4% were born preterm. Intraventricular hemorrhage was identified on cranial ultrasound in 13.3% of infants, with the majority of intraventricular hemorrhage being low-grade (grade I/II). The incidence increased as gestational age decreased such that intraventricular hemorrhage was present in 8.7% of term infants, 19.2% of late preterm infants, 26.3% of moderately preterm infants, and 53.3% of very preterm infants. There was no difference in intraventricular hemorrhage rates between cardiac diagnoses. Additionally, the rate of intraventricular hemorrhage did not increase after cardiac intervention, with only three infants demonstrating new/worsening high-grade (grade III/IV) intraventricular hemorrhage after surgery. In a multivariate model, only gestational age at birth and African-American race were predictors

    Full Text Available BackgroundThe survival rate of newborns with severe congenital abdominal wall defects has increased. After successfully addressing life-threatening complications, it is necessary to focus on the cosmetic and functional outcomes of the abdominal wall.MethodsWe performed a chart review of five cases treated in our institution.ResultsFive patients, ranging from seven to 18 years of age, underwent the following surgical approaches: simple approximation of the rectus abdominis fascia, the rectus abdominis sheath turnover flap, the placement of submuscular tissue expanders, mesh repair, or a combination of these techniques depending on the characteristics of each individual case.ConclusionsPatients with severe congenital abdominal wall defects require individualized surgical treatment to address both the aesthetic and functional issues related to the sequelae of their defects.

    Full Text Available Despite the fact that the influenza virus pathogenicity factors have been well studied in vitro, in vivo lack is presented in understanding of the those risk factors, objective and laboratory parameters, which related most of all to the fatal virus-associated community-aquired pneumonia (CAP. That is why the purpose of the study was to study the clinical and laboratory characteristics of patients with severe virus-associated CAP during the 2015–2016 influenza epidemic and their role as predictors of patients’ mortality. To do this, patients with severe virus-associated CAP were examined. They were divided into 2 groups depending on the outcome of treatment: 1st- deaths from the virus-associated severe CAP and 2nd - patients with successful treatment of the severe virus-associated CAP. Special statistical method was used – one-dimensional analysis of variance to compare individual parameters between the two groups of patients (surviving and deceased. Pearson χ2 test (contingency table was used for categorical variables. Factors that were significant predictors of mortality as a result of univariate analysis were tested using multifactorial analysis using logistic regression. In the final model, each parameter must have had a significant impact on mortality. It was found that risk factors for death in patients with severe virus-associated CAP according to univariate analysis were: presence of obesity, disorders of consciousness, BH≥35 min, SaO2<80%, PaO2<50 mm Hg, mmHg PaCO2 ≥50 mmHg during hospitalization. Independent predictors of mortality according to the logistic regression are the presence of obesity, disorders of consciousness, PaO2<50 mm Hg, mmHg PaCO2 ≥50 mmHg. Given that among clinical and laboratory parameters key parameters that significantly influence the outcome, are indicators of the severity of hypoxia and hypoxemia, a major step in determining the severity of the patients with virus-associated severe emergency is

    Congenital malformations (CMF) are major causes of fetal demise which can be detected antenatally by Ultrasonography (USG). We studied 100 perinatal autopsies for CMF. Sensitivity of USG was determined and accuracy of USG with that of autopsy was compared. At Autopsy 134 individual CMF were seen in 40 cases. The sensitivity of USG in detecting major CMF was 54.47%. A complete agreement between autopsy and USG findings was seen in 13/40 (32.5%) and partial agreement in 17/40 (42.5%) fetuses while autopsy completely changed antenatal diagnosis in 10/40 (25%) fetuses. Major findings were added in all 17 fetuses with partial agreement. In 2 cases, CMF suspected on USG were not detected on autopsy due to fetal maceration. Autopsy significantly adds to the prenatal USG diagnosis and may help in predicting the probability of recurrence, and thus counseling the affected couple to prevent any such future event.

    The presynaptic, high-affinity choline transporter is a critical determinant of signalling by the neurotransmitter acetylcholine at both central and peripheral cholinergic synapses, including the neuromuscular junction. Here we describe an autosomal recessive presynaptic congenital myasthenic syndrome presenting with a broad clinical phenotype due to homozygous choline transporter missense mutations. The clinical phenotype ranges from the classical presentation of a congenital myasthenic syndrome in one patient (p.Pro210Leu), to severe neurodevelopmental delay with brain atrophy (p.Ser94Arg) and extend the clinical outcomes to a more severe spectrum with infantile lethality (p.Val112Glu). Cells transfected with mutant transporter construct revealed a virtually complete loss of transport activity that was paralleled by a reduction in transporter cell surface expression. Consistent with these findings, studies to determine the impact of gene mutations on the trafficking of the Caenorhabditis elegans choline transporter orthologue revealed deficits in transporter export to axons and nerve terminals. These findings contrast with our previous findings in autosomal dominant distal hereditary motor neuropathy of a dominant-negative frameshift mutation at the C-terminus of choline transporter that was associated with significantly reduced, but not completely abrogated choline transporter function. Together our findings define divergent neuropathological outcomes arising from different classes of choline transporter mutation with distinct disease processes and modes of inheritance. These findings underscore the essential role played by the choline transporter in sustaining acetylcholine neurotransmission at both central and neuromuscular synapses, with important implications for treatment and drug selection. © The Author (2017).

    2004-01-01

    The case of a 22 years old female patient who at 16 years of age suffered a closed thoracic trauma during a car accident is reported. She underwent surgery under extra corporeal circulation with femoro-femoral cannulation with the diagnosis of rupture of the left atrium. a large aneurysm of the left auricle without evidence of heart trauma, pericardial leakage or hemo pericardium, was found. The surgeon decided not to perform surgery on the aneurysm and to withdraw the extra corporeal circulation, proceeding to suture the patient, who was released with the recommendation of performing additional studies in order to consider the handling of the aneurysm. Six years later she is sent to our institution with the diagnosis of cerebral embolism with left hemiparesis, and a giant partially thrombosed left auricle aneurysm. With a diagnosis of an embolizing partially thrombosed aneurysm of the left auricle she underwent surgery under extracorporeal circulation in order to resect it. The case with the intraoperative findings and the surgical technique are described. Different manifestations and expressions of this potentially lethal rare entity are detailed, concluding that it is imperative to resect surgically the aneurysm once it has been diagnosed

  2. Congenital scoliosis - presentation of three severe cases treated conservatively.

    2008-01-01

    In view of the very limited data about conservative treatment of patients with congenital scoliosis (CS) available, early surgery is suggested already in mild cases with formation failures in the first three years of life. It is common sense that patients with failures of segmentation will not benefit from conservative treatment at all and the same applies to failures of formation with curves of >50 degrees in infancy. Two patients with rib synostosis denied surgery before entering the pubertal growth spurt. These patients have been treated conservatively with braces and Scoliosis In-Patient Rehabilitation (SIR) and now are beyond the pubertal growth spurt. One patient with a formation failure and a curve of >50 degrees lumbar has been treated with the help of braces and physiotherapy from 1.6 years on and is still under treatment now at the age of 15 years. Severe decompensation was prevented in the two patients with failure of segmentation, however a severe thoracic deformity is evident with underdeveloped lung function and severe restrictive ventilation disorder. The patient with failure of formation is well developed, now without cosmetic or physical complaints although his curve progressed at the end of the growth spurt due to final mal-compliance. Failures of segmentation should be advised to have surgery before entering the pubertal growth spurt. In case they deny, conservative treatment can at least in part be beneficial. For patients with failures of formation conservative treatment should be suggested in the first place because long-term outcomes of early surgery beyond pubertal growth spurt are not yet revealed.

    Severe congenital neutropenia (SCN) is characterized by low numbers of peripheral neutrophil granulocytes and a predisposition to life-threatening bacterial infections. We describe a novel genetic SCN type in 2 unrelated families associated with recessively inherited loss-of-function mutations in CSF3R, encoding the granulocyte colony-stimulating factor (G-CSF) receptor. Family A, with 3 affected children, carried a homozygous missense mutation (NM_000760.3:c.922C>T, NP_000751.1:p.Arg308Cys), which resulted in perturbed N-glycosylation and aberrant localization to the cell surface. Family B, with 1 affected infant, carried compound heterozygous deletions provoking frameshifts and premature stop codons (NM_000760.3:c.948_963del, NP_000751.1:p.Gly316fsTer322 and NM_000760.3:c.1245del, NP_000751.1:p.Gly415fsTer432). Despite peripheral SCN, all patients had morphologic evidence of full myeloid cell maturation in bone marrow. None of the patients responded to treatment with recombinant human G-CSF. Our study highlights the genetic and morphologic SCN variability and provides evidence both for functional importance and redundancy of G-CSF receptor-mediated signaling in human granulopoiesis. © 2014 by The American Society of Hematology.

  4. Game of clones: the genomic evolution of severe congenital neutropenia.

    2015-01-01

    Severe congenital neutropenia (SCN) is a genetically heterogeneous condition of bone marrow failure usually diagnosed in early childhood and characterized by a chronic and severe shortage of neutrophils. It is now well-established that mutations in HAX1 and ELANE (and more rarely in other genes) are the genetic cause of SCN. In contrast, it has remained unclear how these mutations affect neutrophil development. Innovative models based on induced pluripotent stem cell technology are being explored to address this issue. These days, most SCN patients receive life-long treatment with granulocyte colony-stimulating factor (G-CSF, CSF3). CSF3 therapy has greatly improved the life expectancy of SCN patients, but also unveiled a high frequency of progression toward myelodysplastic syndrome (MDS) and therapy refractory acute myeloid leukemia (AML). Expansion of hematopoietic clones with acquired mutations in the gene encoding the G-CSF receptor (CSF3R) is regularly seen in SCN patients and AML usually descends from one of these CSF3R mutant clones. These findings raised the questions how CSF3R mutations affect CSF3 responses of myeloid progenitors, how they contribute to the pre-leukemic state of SCN, and which additional events are responsible for progression to leukemia. The vast (sub)clonal heterogeneity of AML and the presence of AML-associated mutations in normally aged hematopoietic clones make it often difficult to determine which mutations are responsible for the leukemic process. Leukemia predisposition syndromes such as SCN are unique disease models to identify the sequential acquisition of these mutations and to interrogate how they contribute to clonal selection and leukemic evolution. © 2015 by The American Society of Hematology.

    The development and safety certification of less lethal projectiles require an understanding of the influence of projectile parameters on projectile-chest interaction and on the resulting terminal effect. Several energy-based criteria have been developed for chest injury assessment. Many studies consider kinetic energy (KE) or energy density as the only projectile parameter influencing terminal effect. In a common KE range (100-160 J), analysis of the firing tests of two 40 mm projectiles of different masses on animal surrogates has been made in order to investigate the severity of the injuries in the thoracic region. Experimental results have shown that KE and calibre are not sufficient to discriminate between the two projectiles as regards their injury potential. Parameters, such as momentum, shape and impedance, influence the projectile-chest interaction and terminal effect. A simplified finite element model of projectile-structure interaction confirms the experimental tendencies. Within the range of ballistic parameters used, it has been demonstrated that maximum thoracic deflection is a useful parameter to predict the skeletal level of injury, and it largely depends on the projectile pre-impact momentum. However, numerical simulations show that these results are merely valid for the experimental conditions used and cannot be generalised. Nevertheless, the transmitted impulse seems to be a more general factor governing the thorax deflection.

  8. Compound heterozygous loss-of-function mutations in KIF20A are associated with a novel lethal congenital cardiomyopathy in two siblings.

    Full Text Available Congenital or neonatal cardiomyopathies are commonly associated with a poor prognosis and have multiple etiologies. In two siblings, a male and female, we identified an undescribed type of lethal congenital restrictive cardiomyopathy affecting the right ventricle. We hypothesized a novel autosomal recessive condition. To identify the cause, we performed genetic, in vitro and in vivo studies. Genome-wide SNP typing and parametric linkage analysis was done in a recessive model to identify candidate regions. Exome sequencing analysis was done in unaffected and affected siblings. In the linkage regions, we selected candidate genes that harbor two rare variants with predicted functional effects in the patients and for which the unaffected sibling is either heterozygous or homozygous reference. We identified two compound heterozygous variants in KIF20A; a maternal missense variant (c.544C>T: p.R182W and a paternal frameshift mutation (c.1905delT: p.S635Tfs*15. Functional studies confirmed that the R182W mutation creates an ATPase defective form of KIF20A which is not able to support efficient transport of Aurora B as part of the chromosomal passenger complex. Due to this, Aurora B remains trapped on chromatin in dividing cells and fails to translocate to the spindle midzone during cytokinesis. Translational blocking of KIF20A in a zebrafish model resulted in a cardiomyopathy phenotype. We identified a novel autosomal recessive congenital restrictive cardiomyopathy, caused by a near complete loss-of-function of KIF20A. This finding further illustrates the relationship of cytokinesis and congenital cardiomyopathy.

    A case report of a patient with severe proliferative retinopathy due to congenital lipodystrophy. We reviewed the medical history, imaging, and surgical procedures of a 25-year-old woman with a history of congenital lipodystrophy, presenting with bilateral combined tractional and exudative retinal detachment, poorly controlled diabetes mellitus, and extreme dislipidemia. The patient underwent retinal detachment repair surgery both eyes. On the last follow-up, both retinae were flat, and visual acuity had improved in the right eye to J3 for near and finger counting 3 m for distance. Surgery combining pars plana vitrectomy and scleral bucking successfully flattened both retinae and significantly improved visual acuity in one eye in this case of bilateral retinal detachment with combined tractional and exudative components in a patient with congenital lipodystrophy. Surgical control of retinal complications is thus possible, provided there is adequate control of the underlying risk factors.

    In adults with severe congenital facial disfigurement, assessment of long-term psychological impact remains limited. This study determines the long-term psychological functioning in these patients and evaluates differences compared with patients with acquired facial disfigurement and a non-facially disfigured reference group. Also explored is the extent to which psychological functioning of the congenital group is related to satisfaction with facial appearance, fear of negative appearance evaluation by others, self-esteem, and severity of the facial deformity. Fifty-nine adults with severe congenital facial disfigurement, 59 adults with a traumatically acquired facial deformity in adulthood, and 120 non-facially disfigured adults completed standardized psychological, physical, and demographic questionnaires, including the Fear of Negative Appearance Evaluation Scale, the Rosenberg Self-Esteem Scale, the Hospital Anxiety and Depression Scale, the Achenbach Adult Self-Report, the 36-Item Short-Form Health Survey, and a visual analogue scale. Adults with severe congenital facial disfigurement had relatively normal psychological functioning but appeared more prone to internalizing problems than the non-facially disfigured adults. Compared with patients with an acquired facial deformity, the congenital group displayed fewer problems on the physical component score of quality of life only. Satisfaction with facial appearance, fear of negative appearance evaluation, and self-esteem were good predictors of the different aspects of psychological functioning, with the exception of the physical component score of quality of life. Improving satisfaction with facial appearance (by surgery), enhancing self-esteem, or lowering fear of negative appearance evaluation (by psychological support) may enhance long-term psychological functioning. Future research should focus on the individual patient and risk factors for maladjustment. Risk, II.

    Full Text Available Little is known about women’s comparative attitudes towards prenatal testing for different categories of genetic disorders. We interviewed women who delivered healthy infants within the past year and assessed attitudes towards prenatal screening and diagnostic testing, as well as pregnancy termination, for Down syndrome (DS, fragile X (FraX, cystic fibrosis (CF, spinal muscular atrophy (SMA, phenylketonuria (PKU and congenital heart defects (CHD. Ninety-five women aged 21 to 48 years participated, of whom 60% were Caucasian, 23% Asian, 10% Latina and 7% African American; 82% were college graduates. Ninety-five to ninety-eight percent indicated that they would have screening for each condition, and the majority would have amniocentesis (64% for PKU to 72% for SMA. Inclinations regarding pregnancy termination varied by condition: Whereas only 10% reported they would probably or definitely terminate a pregnancy for CHD, 41% indicated they would do so for DS and 62% for SMA. Most women in this cohort reported that they would undergo screening for all six conditions presented, the majority without the intent to terminate an affected pregnancy. These women were least inclined to terminate treatable disorders (PKU, CHD versus those associated with intellectual disability (DS, FraX and were most likely to terminate for SMA, typically lethal in childhood.

    2018-03-01

    Full Text Available Introduction: We present a rare case of severe penile torsion of 180° along with giant congenital anterior urethral diverticula. Presentation of these two rare anomalies together is extremely rare and has not been reported yet. The extreme rarity of the case and its management warrants this presentation. Observation: A 5 years old boy presented to us as a case of epispadias with post-void dribbling and wetting of the underwears. On examination, he was found to be a case of severe congenital penile torsion with diversion and rotation of median raphae in a counterclockwise fashion upto the midline dorsally confirming 180° torsion. During voiding, there was appearance of a swelling in distal penile region with passage of urinary drops while compressing it. Micturating cystourethrogram showed diverticula in penile and bulbar urethra. Torsion was completely corrected by penile de-gloving in a plane between two layers of buck fascia and mobilization of the urethra along with spongiosum proximally upto the penoscrotal junction and distally upto the glans. Diverticula was laid open and underwent urethroplasty along with double breasting of thickened diverticular tissue. Torsion was completely corrected after surgery. Post-operative recovery was uneventful. Urine culture was sterile and uroflowmetry showed maximal urinary flow of 12 ml/s at 3 months postoperatively. Conclusions: Penile de-gloving and adequate urethral mobilization corrects the severe penile torsion of 180°. Correction of severe torsion and urethroplasty is feasible in a single stage with good results.

    In humans, GLE1 is mutated in lethal congenital contracture syndrome 1 (LCCS1) leading to prenatal death of all affected fetuses. Although the molecular roles of Gle1 in nuclear mRNA export and translation have been documented, no animal models for this disease have been reported. To elucidate the function of Gle1 in vertebrate development, we used the zebrafish (Danio rerio) model system. gle1 mRNA is maternally deposited and widely expressed. Altering Gle1 using an insertional mutant or antisense morpholinos results in multiple defects, including immobility, small eyes, diminished pharyngeal arches, curved body axis, edema, underdeveloped intestine and cell death in the central nervous system. These phenotypes parallel those observed in LCCS1 human fetuses. Gle1 depletion also results in reduction of motoneurons and aberrant arborization of motor axons. Unexpectedly, the motoneuron deficiency results from apoptosis of neural precursors, not of differentiated motoneurons. Mosaic analyses further indicate that Gle1 activity is required extrinsically in the environment for normal motor axon arborization. Importantly, the zebrafish phenotypes caused by Gle1 deficiency are only rescued by expressing wild-type human GLE1 and not by the disease-linked Fin(Major) mutant form of GLE1. Together, our studies provide the first functional characterization of Gle1 in vertebrate development and reveal its essential role in actively dividing cells. We propose that defective GLE1 function in human LCCS1 results in both neurogenic and non-neurogenic defects linked to the apoptosis of proliferative organ precursors.

A 17-month-old girl (patient 1) was admitted due to cervical lymphadenitis caused by methicillin-resistant Staphylococcus aureus, with neutropenia. She had Pseudomonas aeruginosa sepsis and peritonitis with perforated appendicitis at 8-month of age. Her sister, a 37-month-old girl (patient 2), had recurrent stomatitis with profound neutropenia, and her mother, a 32-yr-old woman (patient 3), had had recurrent stomatitis until her early 20s with neutropenia. We found an ELANE gene mutation (c.597+1G > A) from them in direct DNA sequencing analysis. Patients 1 and 2 did not respond to granulocyte colony stimulating factor and patient 1 was treated with prolonged antibiotics and excision. We demonstrated inherited SCN cases showing different severity even with the same mutation of the ELANE gene in a family.

    Congenital neutropenia is characterized by a severe reduction in absolute neutrophil counts, resulting in an almost total absence of neutrophils. It is well known that severe neutropenia affects periodontal status. Oral manifestations include ulcerations, gingival desquamation, gingival inflammation, attachment loss, and alveolar bone loss which may result in tooth loss. Treatment with granulocyte-colony stimulating factor (G-CSF) may improve this periodontal condition. This article reports the relationship between periodontal disease status and peripheral neutrophil levels in two consanguineous siblings with severe congenital neutropenia who did not receive routine G-CSF for 2 years prior to examination. Both siblings were given scaling, root planing, and periodontal prophylaxis in regular follow-up visits. This report demonstrates that periodontal therapy supported by adequate oral hygiene may result in restoration of neutrophil counts in siblings with congenital neutropenia.

    There is a high prevalence of congenital heart disease (CHD) in Down syndrome (DS) patients. Children with DS and CHD also present greater susceptibility to pulmonary infections than those without CHD. To investigate the prevalence and types of CHD and their association with severe infections in children with DS in southern Brazil seen in a reference outpatient clinic. Children aged between six and 48 months with a diagnosis of DS were included consecutively in the period May 2001 to May 2012, and the presence of CHD and severe infections (pneumonia and sepsis) was investigated, classified and analyzed. A total of 127 patients were included, of whom 89 (70.1%) had some type of CHD, 33 (37.7%) of them requiring surgical correction. Severe infections (pneumonia and sepsis) were seen in 23.6% and 5.5%, respectively. Of the cases of pneumonia, 70% had associated CHD (p=0.001) and of those with sepsis, 85% presented CHD (p=0.001).

    Full Text Available Background and Aim: Research conducted since the early 1900s has consistently identified differences between deaf and hearing children on performance of a wide variety of motor tasks, most notably balance. Our study was performed to test static and dynamic balance skills in congenital severe to profound hearing impaired children in comparison with normal age-matched children.Methods: This cross-sectional study was conducted on 30 severe to profound hearing impaired and 40 normal children with age 6 to 10 years old. Bruininks-Oseretsky test of motor proficiency 2, balance subset with 9 parts was used for evaluation of balance skills.Results: Hearing-impaired children showed 16.7 to 100% fail results in 7 parts of the balance subset. In normal children fail result was revealed just in 3 parts of the balance subset from 2.5 to 57.5%, and differences between two groups were significant (p<0.0001. There was a significant difference between two groups in two static balance skills of standing on one leg on a line and standing on one leg on a balance beam with eyes closed (p<0.0001.conclusion: It seems that development of static balance skills are longer than dynamic ones. Because severe to profound hearing-impaired children showed more weakness than normal children in both static and dynamic balance abilities, functional tests of balance proficiency can help to identify balance disorders in these children.

    Osteogenesis imperfecta (OI) is a genetic disorder characterised by low bone mineral density resulting in fractures. 85-90% of patients with OI carry a variant in the type 1 collagen genes, COL1A1 and COL1A2, which follows an autosomal dominant pattern of inheritance. However, within the last two decades, there have been growing number of variants identified in genes that follow an autosomal recessive pattern of inheritance. Our proband is a child born in Mexico with multiple fractures of ribs, minimal calvarial mineralisation, platyspondyly, marked compression and deformed long bones. He also presented with significant hydranencephaly, requiring ventilatory support from birth, and died at 8days of age. A homozygous c.338_357delins22 variant in exon 2 of SERPINH1 was identified. This gene encodes heat shock protein 47, a collagen-specific chaperone which binds to the procollagen triple helix and is responsible for collagen stabilisation in the endoplasmic reticulum. There is minimal literature on the mechanism of action for variants in SERPINH1 resulting in osteogenesis imperfecta. Here we discuss this rare, previously unreported variant, and expand on the phenotypic presentation of this novel variant resulting in a severe, lethal phenotype of OI in association with hydranencephaly.

    This study examines university graduation rates among individuals with congenital heart disease (CHD) in comparison to their healthy peers. The effect of disease severity, type of surgery, and timing of surgery on graduation rate was also evaluated. One hundred forty-five male patients with CHD at military age were enrolled in the study between the dates of January 2005 and May 2007. Severity of disease was operationalised in term of initial diagnosis (According to classification of 32th ACC Bethesta Conference Task Force 1). University graduation rates of among two groups of CHD patients (mild disease (group 1) or moderate to severe disease (group 2)) are compared to each other and to healthy peers. Patients with CHD have reduced rates of participation in higher education compared with healthy individuals (13.1% vs 20.7%, p=0.01). Furthermore, this negative effect on education participation rate is independent of the severity of disease (group 1, 16.4%, p=0.01; group 2, 9.7%, pgraduation rate was relatively higher in patients with mild disease severity, no significant difference was found between the two patient groups (p=0.23). Having an operation does not effect graduation rate (p=0.58), however greater age at the time of operation increases the likelihood of graduation (p=0.02). Being born with CHD significantly reduces the chance of completing higher education. This negative impact on university graduation rate is independent of the severity of the disease. No negative effects of disease related surgery or subsequent corrective surgery on education were observed. Patients who were operated on later in life were more likely to complete university education. Mean operation age of this group corresponds to the typical age during the last year of elementary school in Turkey.

    Severe congenital factor VII (FVII) deficiency is a rare bleeding disorder. Prophylaxis with replacement therapy has been suggested to patients, yet the most beneficial dosing regimens and therapy intervals are still to be defined. Due to the lack of evidence-based data, we hereby present our experience with long-term administration and monitoring primary prophylaxis in children with severe FVII deficiency and an extremely high bleeding risk. Four children with familial FVII deficiency, treated by prophylactic recombinant activated factor VII (rFVIIa), 15-30μg/kg/dose, given 2-3 times weekly since infancy, are discussed. Clinical follow up and monitoring laboratory assays, including thrombin generation, measured at various time points after prophylactic rFVIIa administration are presented. Among our treated patients neither FVII activity nor thrombin generation parameters (both already declined 24h post rFVIIa administration) were able to predict the impact of prophylaxis, and could not be used as surrogate markers in order to assess the most beneficial treatment frequency. However, the long clinical follow-up and comprehensive laboratory assessment performed, have shown that early primary prophylaxis as administered in our cohort was safe and effective.

    Congenital generalized lipodystrophy (CGL) with severe hypertriglyceridemia in a children less than 1 year of age is associated with worse metabolic risk. We used data from patient records, as well as extensive literature research to write the manuscript. We report the case of an infant with typical phenotype of CGL and hypertriglyceridemia of 1,360 mg/dL who was treated with bezafibrate at a dose of 30 to 60 mg/day from age 11 months to 5.5 years old, with a measurement of nadir of triglycerides of 55 mg/dL. Clinical evolution and clinical laboratory tests before and after bezafibrate were carried out over 5 years and 6 months. Phenotype was classified as CGL type 2. Despite the efficient control of hypertriglyceridemia and absence of development of diabetes mellitus, the use of bezafibrate did not prevent the onset of hepatic steatosis during evolution. Hypolipidemic therapy with bezafibrate proved effective in maintaining the levels of triglycerides, cholesterol and its fractions at normal levels, and its use was not correlated with severe side effects during the described period.

  14. Anaesthesia management in a patient with a severe biotinidase deficiency for congenital scoliosis repair

    Full Text Available A 17 year old female patient with a biotinidase enzyme deficiency, cerebral palsy, aphamis, generalized hyperreflexia and spasticity, epilepsy and mental retardation came for the severe kyphoscoliotic deformity correction. Biotinidase enzyme deficiency is an autosomal recessive disorder with incidence of 1:60,000 neonatal birth. Treatment with biotin results in a rapid biochemical and clinical improvement. This enzyme deficiency involves neurological, neuromuscular, respiratory, dermatological and immunological problems. If untreated it can lead to convulsions, coma and death. Cobb’s angle that measures the curvature of scoliosis, determined by measurements made on X rays in this case was 120° with clinical presentation of recurrent respiratory tract infection, inability to maintain sagittal posture, inability to eat or feed and difficulty in nursing care. Anaesthetic management in these patients should focus primarily on associated comorbidities and congenital anomalies affecting the course of the perioperative management and thereafter comprehensive preoperative strategies must be executed to enhance the safety profile during the surgery.

    Severe congenital neutropenia is an inherited disease characterized by low peripheral blood neutrophils, amenable to bone marrow transplantation. Genetic analysis in the family here described detected a ELA2 splice-site mutation in the affected child and also in his asymptomatic father. The parents requested preimplantation genetic diagnosis (PGD), coupled with HLA matching, to obtain a suitable bone marrow donor for the affected child. A PGD protocol was developed, based on multiplex nested PCR for direct analysis of the ELA2 mutation, flanking polymorphic markers and HLA typing. The amplification efficiency of the mutation was > 90% in single leukocytes from the affected child but only 67% in the father. Analysis of single haploid sperm cells from the father demonstrated three different sperm-cell populations: (1) sperm cells harboring the ELA2 mutation on the 'affected' haplotype, (2) sperm cells without the ELA2 mutation on the 'normal' haplotype, and (3) sperm cells without the ELA2 mutation on the 'affected' haplotype. These data demonstrate that the ELA2 mutation in the father occurred de novo during his embryonic development, resulting in somatic as well as germ-line mosaicism. This conclusion was also taken into consideration when PGD was performed. Copyright (c) 2010 John Wiley & Sons, Ltd.

    Objective: To study the radiological features of severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease so as to make early diagnosis and treatment. We also intend to find the mechanism of these complications. Methods: A total of 9 pediatric cases with severe respiratory complications during cardiac catheterizations were included in the study. The clinical manifestations, radiological features, and corresponding treatments were reviewed. Results: Most of the cases had severe hypoxia, with 6 cases presenting with bradycardia. Opacification of two lung fields was found in 7 cases, pulmonary edema in 1 case, and atelectasis of the upper right lung in 1 case. With intubation, oxygen inhalation and administration of certain drugs, all cases were saved except 1 case with pulmonary edema. Conclusion: Severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease are emergent and critical, and they often presented with various manifestations. Early diagnosis and correct treatment are the key to successful salvage. (authors)

    Microvillous inclusion disease (MVID) is a rare congenital enterocyte disorder causing severe diarrhea and intestinal failure. The objective of this study was to analyze clinical evolution and the most frequent complications of MVID in children receiving parenteral nutrition (PN) and after small-bowel transplantation (SBTx) with the aim to improve treatment strategies and prognosis. From 1995 to 2009, 24 patients (16 boys, median follow-up 4.7 years, range: from birth to 23.5 years) with MVID were admitted to our unit. The recorded parameters included growth, neurological development, liver and renal functions, bone disease, and outcome. Almost half of the children were from consanguineous families from the Mediterranean area. All of the patients completely depended on PN. Four children died of PN complications before 4 years of age. Before or without SBTx, growth failure was common (mean height -2.5 standard deviations [SD]), as was developmental delay (12/24), liver (20/22 with fibrosis) or kidney disease (3/23 with moderate renal insufficiency), and osteoporosis (6/24). Thirteen children underwent SBTx (9 isolated, 4 combined with liver Tx) at a median age of 3.5 years. Follow-up after SBTx was 0.4 to 14 years. Patient survival rates were 63% without SBTx and 77% with SBTx. After SBTx, 4 children experienced catch-up growth. PN in MVID is difficult to manage and requires expertise. Despite improved results in expert centers, the risk of death or irreversible sequelae is higher with PN than after Tx. SBTx, despite being complicated, remains the only hope to improve the quality of life and long-term prognosis of these children.

    We aim to explore the association of a severe congenital malformation (SCM) with postnatal family functioning and parents' separation/divorce and to examine if this association might be moderated by birth order of the child and parental level of education. SCM refers to malformations that, without medical intervention, cause handicap or death. Using the Quebec Longitudinal Study of Child Development, an ongoing population-based birth cohort study initiated in 1998, we compared 1675 families of children with and without a SCM to identify if having a child with a SCM was associated with maternal perception of family functioning. We examined if an SCM was associated with parents' separation and examined parents' education level and birth order of the children to evaluate whether these factors had any moderating effect on the results. There were no significant differences in family functioning between families with and without a SCM child at 5 and 17 months. At 5 months, family functioning was significantly better (P = 0.03) for families with a SCM firstborn child than for families with a SCM child that is not firstborn. For parental separation, no significant differences were observed at 5 and 29 months and 4 years. No significant moderating effects were observed for birth order and parental education on parental separation. Families of children with a SCM do not appear to be at higher risk of family dysfunction within the first 17 months after birth nor of parental separation within the first 4 years after birth. Family functioning tends to be worst in families where the child with SCM is the second or subsequent child born. © 2015 John Wiley & Sons Ltd.

    A 9-month-old boy with congenital kyphoscoliosis secondary to multiple bilateral thoracic pedicle aplasias is presented. This anomaly has rarely been described in the literature. Plain films showed absence of thoracic pedicles bilaterally from T2 to T9, which was better demonstrated on CT multiplanar and 3-D reformatted images. There were no neurological symptoms even though the deformity progressed rapidly. Congenital kyphosis or kyphoscoliosis is often related to spinal anomalies that are located on the anterior aspect of the vertebrae. However, posterior anomalies may also be responsible and should be recognized before neurological complications occur. (orig.)

    Patients with severe congenital facial disfigurement have a long track record of operations and hospital visits by the time they are 18 years old. The fact that their facial deformity is congenital may have an impact on how satisfied these patients are with their appearance. This study evaluated the level of satisfaction with facial appearance of congenital and of acquired facially disfigured adults, and explored demographic, physical and psychological determinants of this satisfaction. Differences compared with non-disfigured adults were examined. Fifty-nine adults with a rare facial cleft, 59 adults with a facial deformity traumatically acquired in adulthood, and a reference group of 201 non-disfigured adults completed standardised demographic, physical and psychological questionnaires. The congenital and acquired groups did not differ significantly in the level of satisfaction with facial appearance, but both were significantly less satisfied than the reference group. In facially disfigured adults, level of education, number of affected facial parts and facial function were determinants of the level of satisfaction. High fear of negative appearance evaluation by others (FNAE) and low self-esteem (SE) were strong psychological determinants. Although FNAE was higher in both patient groups, SE was similar in all three groups. Satisfaction with facial appearance of individuals with a congenital or acquired facial deformity is similar and will seldom reach the level of satisfaction of non-disfigured persons. A combination of surgical correction (with attention for facial profile and restoring facial functions) and psychological help (to increase SE and lower FNAE) may improve patient satisfaction.

    Full Text Available   Background: Mutations of ELA2, the gene encoding neutrophil elastase (NE are known to be associated with cyclic neutropenia (CN and severe congenital neutropenia (SCN. However, high variability of these mutations has been reported. This study was designed to describe the analysis of the ELA2 gene, clinical manifestations and demographic characteristics in patients with CN and SCN.Methods: A series of 21 patients with CN or SCN were selected, based on SCINR criteria, from the immunology ward of the Pediatric Medicine Center, Tehran, Iran, from March 2004 to August 2005. The ELA2 gene, isolated from blood samples, was analyzed using RT-PCR and automated capillary sequencing. Informed consent was obtained under the tenets of the Helsinki Declaration and the Ethical Committee of the Tehran University of Medical Sciences.Results: Kostmann's syndrome and CN was diagnosed in three and 18 patients respectively. Of all the patients, one or two mutations were found in 18 cases (85.7%, including all three patients with SCN and 15 of the patients with CN. Exons two and four had the most mutations (eight and seven cases, respectively. Seven patients had double mutations in two distinct exons. Overall, 16 different mutations were found. At the time of presentation, the mean age of patients was 13.4 ±17.6 months, ranging from one month to seven years. Overall, 61.9% of patients had consanguineous parents. The mean absolute neutrophil count was 830.5 ±419.4 (150-2000/mm3. On average, each patient had been admitted to the hospital 2.2 ±1.6 times. The neutrophil counts of the SCN patients were significantly higher than those of the CN patients. However, there was no significant difference in the neutrophil counts between patients with mutations and those without mutations. All patients with SCN had two or more infectious complications, although the prevalence of infectious or non-infectious complications did not correlate with ELA2 mutations or the

    There is an increasing prevalence of women with congenital heart defects reaching childbearing age. In western countries women tend to give birth at a higher age compared to some decades ago. We evaluated the CARdiac disease in PREGnancy (CARPREG) and modified World Health Organization (mWHO) risk classifications for cardiac complications during pregnancies in women with congenital heart defects and analyzed the impact of age on risk of obstetric and fetal outcome. A single-center observational study of cardiac, obstetric, and neonatal complications with data from cardiac and obstetric records of pregnancies in women with congenital heart disease. Outcomes of 496 pregnancies in 232 women, including induced abortion, miscarriage, stillbirth, and live birth were analyzed regarding complications, maternal age, mode of delivery, and two risk classifications: CARPREG and mWHO. There were 28 induced abortions, 59 fetal loss, 409 deliveries with 412 neonates. Cardiac (14%), obstetric (14%), and neonatal (15%) complications were noted, including one maternal death and five stillbirths. The rate of cesarean section was 19%. Age above 35years was of borderline importance for cardiac complications (p=0.054) and was not a significant additional risk factor for obstetric or neonatal complications. Both risk classifications had moderate clinical utility, with area under the curve (AUC) 0.71 for CARPREG and 0.65 for mWHO on cardiac complications. Pregnancy complications in women with congenital heart disease are common but severe complications are rare. Advanced maternal age does not seem to affect complication rate. Existing risk classification systems are insufficient in predicting complications. Copyright © 2017 Elsevier B.V. All rights reserved.

    1996-01-01

    Transfer of 2 x 10(5) congenic or semiallogenic purified TCR alphabeta+ CD4+ T cells to SCID mice leads to an infiltration of the recipient gut lamina propria and epithelium with a donor-derived CD4+ T cell subset which induces a lethal inflammatory bowel disease (IBD) in the recipients....... In contrast, IBD was not observed in SCID mice transplanted with unfractionated splenic cells. The earliest detectable pathological changes after CD4+ T cell transfer were proliferation and hypertrophy of the entire colonic epithelial layer, including increased mitotic activity, increased expression...... plasma cells were present in the lamina propria of both the small and large intestine. We conclude that low numbers of intraveneously transferred CD4+ T cells induce IBD in SCID mice. In the late stages of CD4+ T cell-induced IBD, the colonic lamina propria becomes infiltrated with macrophages...

    To investigate the application and effectiveness of vascular corrosion technique in preparing fetal cardiovascular cast models, 10 normal fetal heart specimens with other congenital disease (control group) and 18 specimens with severe congenital heart disease (case group) from induced abortions were enrolled in this study from March 2013 to June 2015 in our hospital. Cast models were prepared by injecting casting material into vascular lumen to demonstrate real geometries of fetal cardiovascular system. Casting effectiveness was analyzed in terms of local anatomic structures and different anatomical levels (including overall level, atrioventricular and great vascular system, left-sided and right-sided heart), as well as different trimesters of pregnancy. In our study, all specimens were successfully casted. Casting effectiveness analysis of local anatomic structures showed a mean score from 1.90±1.45 to 3.60±0.52, without significant differences between case and control groups in most local anatomic structures except left ventricle, which had a higher score in control group (P=0.027). Inter-group comparison of casting effectiveness in different anatomical levels showed no significant differences between the two groups. Intra-group comparison also revealed undifferentiated casting effectiveness between atrioventricular and great vascular system, or left-sided and right-sided heart in corresponding group. Third-trimester group had a significantly higher perfusion score in great vascular system than second-trimester group (P=0.046), while the other anatomical levels displayed no such difference. Vascular corrosion technique can be successfully used in fabrication of fetal cardiovascular cast model. It is also a reliable method to demonstrate three-dimensional anatomy of severe congenital heart disease and normal heart in fetus.

    Patients with factor VII deficiency have an increased risk of prolonged perioperative hemorrhage. In this article, the authors present a case of severe factor VII deficiency in a patient who required tooth extraction. A 44-year-old woman with severe congenital factor VII deficiency sought care for a symptomatic, carious, and nonrestorable maxillary right second molar that required extraction. The authors obtained hematologic consultation, and the patient underwent the extraction under general anesthesia in the inpatient setting. Perioperative management included performing relevant laboratory studies, preoperative recombinant factor VII infusion, and postoperative intravenous aminocaproic acid administration. No hemorrhagic complications occurred throughout the perioperative course. The degree of factor VII deficiency correlates poorly with bleeding risk. Perioperative management is variable, requiring preoperative consultation with a hematologist. Copyright © 2015 American Dental Association. Published by Elsevier Inc. All rights reserved.

  11. Cultured cells from a severe combined immunodeficient mouse have a slower than normal rate of repair of potentially lethal damage sensitive to hypertonic treatment

    1995-01-01

    The effects of hypertonic 0.5 M NaCl treatment after irradiation on the repair of DNA damage were examined in fibroblasts of the severe combined immunodeficient (scid) mouse. These cells are hypersensitive to ionizing radiation because of a deficiency in the repair of double-strand breaks. Hypertonic treatment caused radiosensitization due to a fixation of potentially lethal damage (PLD) in scid cells, demonstrating that scid cells normally repair PLD. To assess the kinetics of the repair of PLD, hypertonic treatment was delayed for various times after irradiation. Potentially lethal damage was repaired during these times in isotonic medium at 37 degrees C. It was found that the rate of repair of PLD was much slower in scid cells than in BALB/c 3T3 cells, which have a open-quotes wild-typeclose quotes level of radiosensitivity. This fact indicates that the scid mutation affects the type of repair of PLD that is sensitive to 0.5 M NaCl treatment. In scid hybrid cells containing fragments of human chromosome 8, which complements the radiosensitivity of the scid cells, the rate of repair was restored to a normal level. An enzyme encoded by a gene on chromosome 8 may also be connected with PLD which is sensitive to hypertonic treatment. 29 refs., 3 figs

    A 2-month-old boy was referred for assessment of severe upper gastrointestinal tract bleeding and melena. On physical examination, a continuous murmur was heard over the right upper quadrant of the abdomen. A splenomegaly and dilated veins were also noted on the abdominal wall. Liver functions were normal. There was no history of trauma or jaundice. Doppler ultrasonography, magnetic resonance arteriography and angiography suggested the presence of an intrahepatic arteriovenous fistula between the phrenic artery and the portal vein. Management consisted of successful embolization by coiling of the phrenic artery. To our knowledge this is the first documented case report of a congenital fistula between the phrenic artery and the portal vein.

    Byard, Roger W

    2016-09-01

    Epistaxis or nosebleed refers to bleeding from the nostrils, nasal cavity, or nasopharynx. Occasional cases may present with torrential lethal hemorrhage. Three cases are reported to demonstrate particular features: Case 1: A 51-year-old woman with lethal epistaxis with no obvious bleeding source; Case 2: A 77-year-old man with treated nasopharyngeal carcinoma who died from epistaxis arising from a markedly neovascularized tumor bed; Case 3: A 2-year-old boy with hemophilia B who died from epistaxis with airway obstruction in addition to gastrointestinal bleeding. Epistaxis may be associated with trauma, tumors, vascular malformations, bleeding diatheses, infections, pregnancy, endometriosis, and a variety of different drugs. Careful dissection of the nasal cavity is required to locate the site of hemorrhage and to identify any predisposing conditions. This may be guided by postmortem computerized tomographic angiography (PCTA). Despite careful dissection, however, a source of bleeding may never be identified. © 2016 American Academy of Forensic Sciences.

The etiology is unknown, and the outcome for the affected fetus is rather uncertain. Case report: Mrs RB, a Kuwaiti woman primigravida, married to a non-consanguineous husband, had uneventful antenatal care in a private health service, until she was admitted to the Maternity Hospital, Kuwait, at 31 weeks of gestation with a 3-hour history of ruptured membranes. She had a negative family history for diabetes mellitus, and her past surgical/medical/gynecological history was noncontributory. General physical examination revealed a healthy parturient with normal vital signs, clear lungs and normal heart sounds. Obstetric examination revealed a fundal height compatible with the gestational age; there was a single living fetus in breech presentation; she was not in labor. The mother was managed conservatively with antibiotics and dexamethasone injections. Labor ensued later, progressing rapidly to the second stage. Assisted breech delivery was performed, and a live baby, birth weight 1570 g and Apgar score 3/9, was delivered. The neonate had multiple congenital abnormalities, including fusion of both lower limbs, ambiguous genitalia, cloacal anomaly and tracheoesophageal fistula. The neonate was admitted to the neonatal intensive care unit, fully investigated, managed medically and surgically and eventually discharged home after a hospital stay of 123 days for further management. Conclusion: A case of peculiar fetal anomaly called sirenomelia, the first case in Kuwait, has been presented. Survival of such babies requires costly management with average results

    Full Text Available Background:Transposition of the great arteries (TGA is the most common cyanotic cardiopathy, with an incidence ranging between 0.2 and 0.4 per 1000 live births. Many patients not treated in the first few months of life may progress with severe pulmonary vascular disease. Treatment of these patients may include palliative surgery to redirect the flow at the atrial level.Objective:Report our institutional experience with the palliative Senning procedure in children diagnosed with TGA and double outlet right ventricle with severe pulmonary vascular disease, and to evaluate the early and late clinical progression of the palliative Senning procedure.Methods:Retrospective study based on the evaluation of medical records in the period of 1991 to 2014. Only patients without an indication for definitive surgical treatment of the cardiopathy due to elevated pulmonary pressure were included.Results:After one year of follow-up there was a mean increase in arterial oxygen saturation from 62.1% to 92.5% and a mean decrease in hematocrit from 49.4% to 36.3%. Lung histological analysis was feasible in 16 patients. In 8 patients, pulmonary biopsy grades 3 and 4 were evidenced.Conclusion:The palliative Senning procedure improved arterial oxygen saturation, reduced polycythemia, and provided a better quality of life for patients with TGA with ventricular septal defect, severe pulmonary hypertension, and poor prognosis.

    Ryanodine receptor 1 ( RYR1 ) is an intracellular calcium receptor primarily expressed in skeletal muscle with a role in excitation contraction. Both dominant and recessive mutations in the RYR1 gene cause a range of RYR1 -related myopathies and/or susceptibility to malignant hyperthermia (MH). Recently, an atypical manifestation of ptosis, variably presenting with ophthalmoplegia, facial paralysis, and scoliosis but without significant muscle weakness, has been reported in 9 cases from 4 families with bialleic variants in RYR1 . Two affected children from a consanguineous family with severe congenital ptosis, ophthalmoplegia, scoliosis, and distinctive long faces but without skeletal myopathy were studied. To identify the cause of the hereditary condition, DNA from the proband was subjected to whole exome sequencing (WES). WES revealed a novel homozygous missense variant in RYR1 (c.14066T>A; p.IIe4689Asn), which segregated within the family. Although the phenotype of the affected siblings in this study was similar to previously described cases, the clinical features were more severely expressed. Our findings contribute to the expansion of phenotypes related to RYR1 dysfunction. Additionally, it supports a new RYR1 -related clinical presentation without musculoskeletal involvement. It is important that individuals with RYR1 mutations are considered susceptible to MH, as 70% of the MH cases are caused by mutations in the RYR1 gene.

    Objective  To estimate the risks of major congenital malformations in the offspring of mothers who are underweight (body mass index (BMI) malformation, and subgroups of organ specific malformations diagnosed during the first year of life. Risk ratios were estimated using generalised linear models adjusted for maternal factors, sex of offspring, and birth year. Results  A total of 43 550 (3.5%) offspring had any major congenital malformation, and the most common subgroup was for congenital heart defects (n=20 074; 1.6%). Compared with offspring of normal weight mothers (risk of malformations 3.4%), the proportions and adjusted risk ratios of any major congenital malformation among the offspring of mothers with higher BMI were: overweight, 3.5% and 1.05 (95% confidence interval 1.02 to 1.07); obesity class I, 3.8% and 1.12 (1.08 to 1.15), obesity class II, 4.2% and 1.23 (1.17 to 1.30), and obesity class III, 4.7% and 1.37 (1.26 to 1.49). The risks of congenital heart defects, malformations of the nervous system, and limb defects also progressively increased with BMI from overweight to obesity class III. The largest organ specific relative risks related to maternal overweight and increasing obesity were observed for malformations of the nervous system. Malformations of the genital and digestive systems were also increased in offspring of obese mothers. Conclusions  Risks of any major congenital malformation and several subgroups of organ specific malformations progressively increased with maternal overweight and increasing severity of obesity. For women who are planning pregnancy, efforts should be encouraged to reduce adiposity in those with a BMI above the normal range. Published by the BMJ Publishing Group Limited.

  1. The D173G mutation in ADAMTS-13 causes a severe form of congenital thrombotic thrombocytopenic purpura

    2015-08-13

    Congenital thrombotic thrombocytopenic purpura (TTP) is a rare form of thrombotic microangiopathy, inherited with autosomal recessive mode as a dysfunction or severe deficiency of ADAMTS-13 (A Disintegrin And Metalloprotease with ThromboSpondin 1 repeats Nr. 13), caused by mutations in the ADAMTS-13 gene. About 100 mutations of the ADAMTS-13 gene were identified so far, although only a few characterised by in vitro expression studies. A new Asp to Gly homozygous mutation at position 173 of ADAMTS-13 sequence was identified in a family of Romanian origin, with some members affected by clinical signs of TTP. In two male sons, this mutation caused a severe (< 3 %) deficiency of ADAMTS-13 activity and antigen level, associated with periodic thrombocytopenia, haemolytic anaemia and mild mental confusion. Both parents, who are cousins, showed the same mutation in heterozygous form. Expression studies of the mutant ADAMTS-13, performed in HEK293 cells, showed a severe decrease of the enzyme’s activity and secretion, although the protease was detected inside the cells. Molecular dynamics found that in the D173G mutant the interface area between the metalloprotease domain and the disintegrin-like domain significantly decreases during the simulations, while the proline-rich 20 residues linker region (LR, 285–304) between them undergoes extensive conformational changes. Inter-domain contacts are also significantly less conserved in the mutant compared to the wild-type. Both a decrease of the inter-domain contacts along with a substantial conformational rearrangement of LR interfere with the proper maturation and folding of the mutant ADAMTS-13, thus impairing its secretion.

    CHN is genetically heterogeneous and its genetic basis is difficult to determine on features alone. CNTNAP1 encodes CASPR, integral in the paranodal junction high molecular mass complex. Nineteen individuals with biallelic variants have been described in association with severe congenital hypomyelinating neuropathy, respiratory compromise, profound intellectual disability and death within the first year. We report 7 additional patients ascertained through exome sequencing. We identified 9 novel CNTNAP1 variants in 6 families: three missense variants, four nonsense variants, one frameshift variant and one splice site variant. Significant polyhydramnios occurred in 6/7 pregnancies. Severe respiratory compromise was seen in 6/7 (tracheostomy in 5). A complex neurological phenotype was seen in all patients who had marked brain hypomyelination/demyelination and profound developmental delay. Additional neurological findings included cranial nerve compromise: orobulbar dysfunction in 5/7, facial nerve weakness in 4/7 and vocal cord paresis in 5/7. Dystonia occurred in 2/7 patients and limb contractures in 5/7. All had severe gastroesophageal reflux, and a gastrostomy was required in 5/7. In contrast to most previous reports, only one patient died in the first year of life. Protein modelling was performed for all detected CNTNAP1 variants. We propose a genotype-phenotype correlation, whereby hypomorphic missense variants partially ameliorate the phenotype, prolonging survival. This study suggests that biallelic variants in CNTNAP1 cause a distinct recognisable syndrome, which is not caused by other genes associated with CHN. Neonates presenting with this phenotype will benefit from early genetic definition to inform clinical management and enable essential genetic counselling for their families.

    Full Text Available The purpose of our study was to investigate the characteristics of severe form of influenza A (H1N1 pdm 2009 with a fatal outcome, given the comorbidities. Materials and methods. Medical histories of 105 people who died in hospitals of St. Petersburg for the period of the epidemic of 2015/16 served as material for analysis.The lethality caused by the pandemic virus type A/ H1N1 / 2009 pdm was higher in males. Most of the patients had concomitant chronic diseases in the anamnesis. Obesity was observed in 44.8% (47/105 of patients, diabetes mellitus — 28.5% (30/105, isolated heart disease — 19.0% (20/ 105, combined pathology — 48.6% (51/105. In the first biochemical analysis of blood, creatine phosphokinase, lactate dehydrogenase were increased, total protein and prothrombin consumption index were reduced. The patient's death occurred after 5 days of illness in 88.6% cases, in 11.4% — up to 5 days of illness (inclusive. The analysis of fatal cases up to 5 days of a disease and death from complications (2—4 week didn't find significant differences in the character and frequency of comorbidity. Specific antiviral therapy has been assigned to all patients, but 48 hours later.Bilateral subtotal viral and bacterial pneumonia was identified on the section, in the majority of cases, in 70.5% with hemorrhagic component. 30% patients had cerebral oedema, 41% patients had severe toxic parenchymatouse degeneration of miocardium, liver and kidneys. The pathology of the cardiovascular system, diabetes and obesity worsen the prognosis of the disease. Increased creatine phosphokinase, lactate dehydrogenase, and reduced total protein and prothrombin consumption index can be considered as markers of severe influenza. The ineffectiveness of antiviral therapy due to its late appointment, thus timely initiation of etiotropic treatment is very impotent.

    Objective To explore clinicians’ perspectives on supporting parents’ decision-making following diagnosis of a severe congenital anomaly, and how this is shaped by current policy. Methods This paper reports data collated as part of a larger project examining parents’ decision-making following antenatal diagnosis. The focus of this paper is the data arising from semistructured interviews conducted with 18 clinicians, with findings further supported by data generated from consultations between clinicians and parents. All interviews and consultations were audio-recorded and transcribed verbatim, with analysis based on the constant comparative approach. Results Three key themes emerged which together shape the practice of clinicians working in this area: first, the law governing termination of pregnancy (TOP) and how clinicians believe this influences the context in which decisions about whether to terminate or continue an affected pregnancy are made; second, approaches to the management of cases seen as particularly challenging; and third, how clinicians understand their role when working with parents. These themes combine to create a strong desire on the part of clinicians for parents to engage in a particular ‘rational’ form of decision-making and to be able to demonstrate the enactment of this. This is seen as important in order to ensure the ‘right’ decision has been reached and, particularly when the decision is to terminate, will withstand possible scrutiny. Conclusions The policy context in which these decisions are made strongly shapes how clinicians practise and what they want to see from the parents with whom they work. The ways in which they seek to overcome the difficulties in interpreting the law may result in variations in the offer of late TOP, both between and within units. This may inadvertently affect the options available to women least able to engage in this idealised form of decision-making. PMID:28588110

    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)

    To investigate the long-term effectiveness of transmastoid lateral semicircular canal approach (TMLSCCA) to repair cerebrospinal fluid (CSF) leakage in children associated with recurrent meningitis and severe congenital inner malformation. A retrospective study was conducted in a university hospital, academic medical center. Fifteen children with recurrent meningitis, secondary to severe congenital inner ear malformation, were included in the study. All of them had CSF associated otorrhea and treated using TLSCCA to repair CSF otorrhea by packing the vestibule with muscle and fascia. Observation of the status of postoperative CSF leakage, recurrence of meningitis and complication were conducted. None of the cases had recurrent meningitis and CSF leakage after their TLSCCA procedure in the follow-up period of 1-8.5 years. One case presented with transient facial nerve paralysis and completely recovered 3 months later. TLSCCA for CSF otorrhea in children with recurrent meningitis secondary to congenital inner ear malformation is an alternative approach that offers some advantages.

    There are several types of hydrocephalus, which are characterized based on the location of the cerebrospinal fluid (CSF) accumulation. Physical features of animals with congenital hydrocephalus may include a dome-shaped skull, persistent fontanelle, and bilateral ventrolateral strabismus. Medical therapy involves decreasing the production of CSF. The most common surgical treatment is placement of a ventriculoperitoneal shunt. Postoperative complications may include infection, blockage, drainage abnormalities, and mechanical failure. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Congenital adrenal hyperplasia (CAH due to 21-hydroxylase deficiency results in excess androgen production which can lead to early epiphyseal fusion and short stature. Prader-Willi syndrome (PWS is a genetic disorder resulting from a defect on chromosome 15 due to paternal deletion, maternal uniparental disomy, or imprinting defect. Ninety percent of patients with PWS have short stature. In this article we report a patient with simple-virilizing CAH and PWS who was overtreated with glucocorticoids for CAH and not supplemented with growth hormone for PWS, resulting in a significantly short adult height.

    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.)

  12. Adult siblings with homozygous G6PC3 mutations expand our understanding of the severe congenital neutropenia type 4 (SCN4 phenotype

    2012-11-01

    Full Text Available Abstract Background Severe congenital neutropenia type 4 (SCN4 is an autosomal recessive disorder caused by mutations in the third subunit of the enzyme glucose-6-phosphatase (G6PC3. Its core features are congenital neutropenia and a prominent venous skin pattern, and affected individuals have variable birth defects. Oculocutaneous albinism type 4 (OCA4 is caused by autosomal recessive mutations in SLC45A2. Methods We report a sister and brother from Newfoundland, Canada with complex phenotypes. The sister was previously reported by Cullinane et al., 2011. We performed homozygosity mapping, next generation sequencing and conventional Sanger sequencing to identify mutations that cause the phenotype in this family. We have also summarized clinical data from 49 previously reported SCN4 cases with overlapping phenotypes and interpret the medical histories of these siblings in the context of the literature. Results The siblings’ phenotype is due in part to a homozygous mutation in G6PC3, [c.829C > T, p.Gln277X]. Their ages are 38 and 37 years respectively and they are the oldest SCN4 patients published to date. Both presented with congenital neutropenia and later developed Crohn disease. We suggest that the latter is a previously unrecognized SCN4 manifestation and that not all affected individuals have an intellectual disability. The sister also has a homozygous mutation in SLC45A2, which explains her severe oculocutaneous hypopigmentation. Her brother carried one SLC45A2 mutation and was diagnosed with “partial OCA” in childhood. Conclusions This family highlights that apparently novel syndromes can in fact be caused by two known autosomal recessive disorders.

    An accessory penis is a very rare anomaly. Only five cases have been reported thus far to our knowledge. We present the case of a child aged 2 years and 10 months who had a penis-like structure (containing phallus and glans) attached to the right buttock. Associated anomalies were a non-communicating type of colonic duplication, a paramedian stenosed anal opening, a horse-shoe kidney, posterior urethral valves, scoliosis of the lumbo-sacral spine, polydactyly and equino-varus deformity of the right foot. As far as we can tell, this is the first report of an accessory penis associated with colonic duplication and other congenital anomalies. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Proximal 4p deletion syndrome is a relatively rare genetic condition characterized by dysmorphic facial features, limb anomalies, minor congenital heart defects, hypogonadism, cafe-au-lait spots, developmental delay, tall and thin habitus, and intellectual disability. At present, over 20 cases of this syndrome have been published. However, duplication of the same region in proximal 4p has never been reported. Here, we describe a 2-year-5-month-old boy with severe congenital heart defects, limb anomalies, hypogonadism, distinctive facial features, pre- and postnatal developmental delay, and mild cognitive impairments. A de novo 4.5-Mb interstitial duplication at 4p15.2p15.1 was detected by chromosomal microarray analysis. Next-generation sequencing was employed and confirmed the duplication, but revealed no additional pathogenic variants. Several candidate genes in this interval responsible for the complex clinical phenotype were identified, such as RBPJ, STIM2, CCKAR, and LGI2. The results suggest a novel contiguous gene duplication syndrome. © 2016 S. Karger AG, Basel.

    Full Text Available Early hearing deprivation could affect the development of auditory, language, and vision ability. Insufficient or no stimulation of the auditory cortex during the sensitive periods of plasticity could affect the function of hearing, language, and vision development. Twenty-three infants with congenital severe sensorineural hearing loss (CSSHL and 17 age and sex matched normal hearing subjects were recruited. The amplitude of low frequency fluctuations (ALFF and regional homogeneity (ReHo of the auditory, language, and vision related brain areas were compared between deaf infants and normal subjects. Compared with normal hearing subjects, decreased ALFF and ReHo were observed in auditory and language-related cortex. Increased ALFF and ReHo were observed in vision related cortex, which suggest that hearing and language function were impaired and vision function was enhanced due to the loss of hearing. ALFF of left Brodmann area 45 (BA45 was negatively correlated with deaf duration in infants with CSSHL. ALFF of right BA39 was positively correlated with deaf duration in infants with CSSHL. In conclusion, ALFF and ReHo can reflect the abnormal brain function in language, auditory, and visual information processing in infants with CSSHL. This demonstrates that the development of auditory, language, and vision processing function has been affected by congenital severe sensorineural hearing loss before 4 years of age.

    Congenital lordoscoliosis is an uncommon pathology and its management poses formidable challenge especially in the presence of type 2 respiratory failure and intraspinal anomalies. In such patients standard management protocols are not applicable and may require multistage procedure to minimize risk and optimize results. A 15-year-old girl presented in our hospital emergency services with severe breathing difficulty. She had a severe and rapidly progressing deformity in her back, noted since 6 years of age, associated with severe respiratory distress requiring oxygen and BiPAP support. She was diagnosed to have a severe and rigid congenital right thoracolumbar lordoscoliosis (coronal Cobb's angle: 105° and thoracic lordosis -10°) with type 1 split cord malformation with bony septum extending from T11 to L3. This leads to presentation of restrictive lung disease with type 2 respiratory failure. As her lung condition did not allow for any major procedure, we did a staged procedure rather than executing in a single stage. Controlled axial traction by halogravity was applied initially followed by halo-femoral traction. Four weeks later, this was replaced by halo-pelvic distraction device after a posterior release procedure with asymmetric pedicle substraction osteotomies at T7 and T10. Halo-pelvic distraction continued for 4 more weeks to optimize and correct the deformity. Subsequently definitive posterior stabilization and fusion was done. The detrimental effect of diastematomyelia resection in such cases is clearly evident from literature, so it was left unresected. A good scoliotic correction with improved respiratory function was achieved. Three years follow-up showed no loss of deformity correction, no evidence of pseudarthrosis and a good clinical outcome with reasonably balanced spine. The management of severe and rigid congenital lordoscoliotic deformities with intraspinal anomalies is challenging. Progressive reduction in respiratory volume in untreated

    Congenital amegakaryocytic thrombocytopenia (CAMT) generally begins at birth with severe thrombocytopenia and progresses to pancytopenia. It is caused by mutations in the thrombopoietin receptor gene, the myeloproliferative leukemia virus oncogene (c-MPL). The association between CAMT and c-MPL mutation type has been reported in the literature. Patients with CAMT have been categorized according to their clinical symptoms caused by different mutations. Missense mutations of c-MPL have been classified as type II and these patients have delayed onset of bone marrow failure compared to type I patients. Here we present a girl with severe clinical course of CAMT II having a missense mutation in exon 4 of the c-MPL gene who was admitted to our hospital with intracranial hemorrhage during the newborn period.

    Coffine-Siris syndrome or "fifth digit" syndrome is a multiple congenital anomaly-mental retardation syndrome with severe developmental delay, coarse facial features, hirsutism and absent fifth fingernails or toenails or fifth distal phalanges. The etiology of this syndrome remains uncertain. Here we report a stillborn male baby born from consanguineous parents who might represent a very severe form of Coffine-Siris syndrome with cardiac defect and multiple brain malformations including corpus callosum agenesis and Dandy Walker malformation. To the best of our knowledge, it is the first case leading to intrauterine death. Karyotype and array comparative genomic hybridization were normal; these results give additional support to mendelian inheritance for this syndrome. In our family, the most likely mode of inheritance is autosomal recessive and the recurrence is probably as high as 25%. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

    Urtica dioica agglutinin (UDA) is a small plant monomeric lectin, 8.7 kDa in size, with an N-acetylglucosamine specificity that inhibits viruses from Nidovirales in vitro. In the current study, we first examined the efficacy of UDA on the replication of different SARS-CoV strains in Vero 76 cells. UDA inhibited virus replication in a dose-dependent manner and reduced virus yields of the Urbani strain by 90% at 1.1 ± 0.4 µg/ml in Vero 76 cells. Then, UDA was tested for efficacy in a lethal SARS-CoV-infected BALB/c mouse model. BALB/c mice were infected with two LD50 (575 PFU) of virus for 4 hours before the mice were treated intraperitoneally with UDA at 20, 10, 5 or 0 mg/kg/day for 4 days. Treatment with UDA at 5 mg/kg significantly protected the mice against a lethal infection with mouse-adapted SARS-CoV (p<0.001), but did not significantly reduce virus lung titers. All virus-infected mice receiving UDA treatments were also significantly protected against weight loss (p<0.001). UDA also effectively reduced lung pathology scores. At day 6 after virus exposure, all groups of mice receiving UDA had much lower lung weights than did the placebo-treated mice. Thus, our data suggest that UDA treatment of SARS infection in mice leads to a substantial therapeutic effect that protects mice against death and weight loss. Furthermore, the mode of action of UDA in vitro was further investigated using live SARS-CoV Urbani strain virus and retroviral particles pseudotyped with SARS-CoV spike (S). UDA specifically inhibited the replication of live SARS-CoV or SARS-CoV pseudotyped virus when added just before, but not after, adsorption. These data suggested that UDA likely inhibits SARS-CoV infection by targeting early stages of the replication cycle, namely, adsorption or penetration. In addition, we demonstrated that UDA neutralizes the virus infectivity, presumably by binding to the SARS-CoV spike (S) glycoprotein. Finally, the target molecule for inhibition of virus

  2. Theories of Lethal Mutagenesis: From Error Catastrophe to Lethal Defection.

    RNA viruses get extinct in a process called lethal mutagenesis when subjected to an increase in their mutation rate, for instance, by the action of mutagenic drugs. Several approaches have been proposed to understand this phenomenon. The extinction of RNA viruses by increased mutational pressure was inspired by the concept of the error threshold. The now classic quasispecies model predicts the existence of a limit to the mutation rate beyond which the genetic information of the wild type could not be efficiently transmitted to the next generation. This limit was called the error threshold, and for mutation rates larger than this threshold, the quasispecies was said to enter into error catastrophe. This transition has been assumed to foster the extinction of the whole population. Alternative explanations of lethal mutagenesis have been proposed recently. In the first place, a distinction is made between the error threshold and the extinction threshold, the mutation rate beyond which a population gets extinct. Extinction is explained from the effect the mutation rate has, throughout the mutational load, on the reproductive ability of the whole population. Secondly, lethal defection takes also into account the effect of interactions within mutant spectra, which have been shown to be determinant for the understanding the extinction of RNA virus due to an augmented mutational pressure. Nonetheless, some relevant issues concerning lethal mutagenesis are not completely understood yet, as so survival of the flattest, i.e. the development of resistance to lethal mutagenesis by evolving towards mutationally more robust regions of sequence space, or sublethal mutagenesis, i.e., the increase of the mutation rate below the extinction threshold which may boost the adaptability of RNA virus, increasing their ability to develop resistance to drugs (including mutagens). A better design of antiviral therapies will still require an improvement of our knowledge about lethal

  3. Histone methylations in heart development, congenital and adult heart diseases.

    Heart development comprises myocyte specification, differentiation and cardiac morphogenesis. These processes are regulated by a group of core cardiac transcription factors in a coordinated temporal and spatial manner. Histone methylation is an emerging epigenetic mechanism for regulating gene transcription. Interplay among cardiac transcription factors and histone lysine modifiers plays important role in heart development. Aberrant expression and mutation of the histone lysine modifiers during development and in adult life can cause either embryonic lethality or congenital heart diseases, and influences the response of adult hearts to pathological stresses. In this review, we describe current body of literature on the role of several common histone methylations and their modifying enzymes in heart development, congenital and adult heart diseases.

    To evaluate the phenotype of 15 children with congenital hyperinsulinism (CHI) and profound hearing loss, known as Homozygous 11p15-p14 Deletion syndrome (MIM #606528). Prospective clinical follow-up and genetic analysis by direct sequencing, multiplex ligation-dependent probe amplification, and microsatellite markers. Genetic testing identified the previous described homozygous deletion in 11p15, USH1C:c.(90+592)_ABCC8:c.(2694-528)del. Fourteen patients had severe CHI demanding near-total pancreatectomy. In one patient with mild, transient neonatal hypoglycemia and nonautoimmune diabetes at age 11 years, no additional mutations were found in HNF1A, HNF4A, GCK, INS, and INSR. Retinitis pigmentosa was found in two patients aged 9 and 13 years. No patients had enteropathy or renal tubular defects. Neuromotor development ranged from normal to severe delay with epilepsy. The phenotype of Homozygous 11p15-p14 Deletion syndrome, or Usher-CHI syndrome, includes any severity of neonatal-onset CHI and severe, sensorineural hearing loss. Retinitis pigmentosa and nonautoimmune diabetes may occur in adolescence.

    Club foot, or congenital talipes equinovarus (CTEV), is a congenital deformity with an incidence of 1 in 1000 live births. The deformity is 3-dimensional with 4 components including cavus, forefoot adduction, heel varus and equinus (CAVE). Severity of the CTEV is determined by Dimiglio scoring system. Benign and moderate forms can be treated conservatively but severe and very severe forms require extensive posteromedial soft tissue release for its correction. The posteromedial soft tissue release can be done through medial Turco incision, Cincinnati incision, and Cincinnati incision with medial rotational fasciocutaneous flap. Objective: The objective of this study is to determine the effectiveness of three types of surgical techniques (Medial Turco, Cincinnati and Cincinnati with medial rotational fasciocutaneous flap), used in the posteromedial release of severe CTEV. Methodology: This Interventional Longitudinal study was conducted at Department of Orthopedic Surgery and Traumatology Mayo Hospital Lahore for a period of one year. A total of 45 patients were diagnosed as severe CTEV and 15 cases were randomly divided in three groups each. Patients were operated and followed-up in OPD by Dimiglio scoring and wound healing at 0, 4th and 18th week postoperatively to determine the amount of correction. Data was analyzed using SPSS 16. Results: Patients in Group-A were treated with Cincinnati with medial rotational fasciocutaneous flap, in group B with Cincinnati Technique and in group-C with Medial Turco Technique. In group A, 7 (46.7%) cases had excellent outcome while 8 (53.3%) cases had good outcome. In group B, 2 (13.3%) cases had excellent outcome, 10 (66.7%) cases had good outcome and 3 (20%) cases had fair outcome. In group C, none of the case had excellent outcome while 9 (60%) cases had good outcome and 6 (40%) cases had fair outcome depending upon Dimiglio scoring. There was significant difference among all groups for final outcome of the incision type

    Full Text Available An 8-week old 3-kilogram male baby was brought to this tertiary care hospital with respiratory distress, marked tracheal tug, poor feeding and a heart rate of 46/minute. The child had been referred from a peripheral hospital as a case of neonatal lupus with complete congenital heart block. The mother was seropositive for systemic lupus erythematosus with a history of two abortions. Evaluation on admission revealed a heart rate between 40-60/ minute, respiratory rate 40-50/ minute, inspiratory stridor, bilateral crepitations, chest retrac-tion and a marked tracheal tug that improved with prone positioning. Electrocardiography and echocardiography confirmed complete congenital heart block with cardiomegaly and mild left ventricular dysfunction. Keeping in view the impending congestive heart failure, possible early cardiomyopathy and the bad obstetric history ur-gent pacemaker implantation was planned to allow early recovery of the child. The anaesthetic risk was high due to the heart block, ventricular dysfunction, laryngomalacia, severe tracheal tug and anticipated difficult weaning from controlled ventilation. General anaesthesia was administered with endotracheal tube and con-trolled ventilation using ketamine, rocuronium and sufentanil. For patient safety invasive monitoring was pro-vided and external pacing was kept standby. Epicardial pacemaker leads were implanted onto the left ventricu-lar wall through a left anterior 6th intercostal space thoracotomy. The child was electively ventilated for two post operative days. The tracheal tug and secretions gradually subsided over 2 weeks with oxygen, antibiotics, steroids, bronchodilators and physiotherapy. At the time of discharge from hospital 2 weeks after the implant the child was feeding well, tracheal tug was minimal and the lungs were clear.

    Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported. © 2016 Wiley Periodicals, Inc.

    2017-01-01

    A 55-year-old wheelchair-bound woman with severe cerebral palsy was found at autopsy to have marked distention of the stomach due to a volvulus. The stomach was viable, and filled with air and fluid and had pushed the left dome of the diaphragm upwards causing marked compression of the left lung with a mediastinal shift to the right (including the heart). There was no evidence of gastric perforation, ischaemic necrosis or peritonitis. Removal of the organ block revealed marked kyphoscoliosis. Histology confirmed the viability of the stomach and biochemistry showed no dehydration. Death in cases of acute gastric volvulus usually occurs because of compromise of the gastric blood supply resulting in ischaemic necrosis with distention from swallowed air and fluid resulting in perforation with lethal peritonitis. Hypovolaemic shock may also occur. However, the current case demonstrates an alternative lethal mechanism, that of respiratory compromise due to marked thoracic organ compression.

    To describe intellectual, motor, and school-associated outcome in young adults with early treated congenital hypothyroidism (CH) and to study the association between long-term outcome and CH variables acting at different points in time during early development (CH severity and early L-thyroxine treatment levels [0-6 years]). Neuropsychological tests were administered to all 49 subjects with CH identified during the first 3 years of the Norwegian neonatal screening program (1979-1981) at a mean age of 20 years and to 41 sibling control subjects (mean age: 21 years). The CH group attained significantly lower scores than control subjects on intellectual, motor, and school-associated tests (total IQ: 102.4 [standard deviation: 13] vs 111.4 [standard deviation: 13]). Twelve (24%) of the 49 CH subjects had not completed senior high school, in contrast to 6% of the control subjects. CH severity (pretreatment serum thyroxine [T4]) correlated primarily with motor tests, whereas early L-thyroxine treatment levels were related to verbal IQ and school-associated tests. In multiple regression analysis, initial L-thyroxine dose (beta = 0.32) and mean serum T4 level during the second year (beta = 0.48) predicted Verbal IQ, whereas mean serum T4 level during the second year (beta = 0.44) predicted Arithmetic. Long-term outcome revealed enduring cognitive and motor deficits in young adults with CH relative to control subjects. Verbal functions and Arithmetic were associated with L-thyroxine treatment variables, suggesting that more optimal treatment might be possible. Motor outcome was associated with CH severity, indicating a prenatal effect.

    A 2-yr-old boy presented profound developmental delay, failure to thrive, ataxia, hypotonia, and tonic-clonic seizures that caused the death of the patient. Targeted and whole exome sequencing revealed two heterozygous missense variants: a novel mutation in the KCNJ10 gene that encodes for the inward-rectifying K + channel Kir4.1 and another previously characterized mutation in KCNT1 that encodes for the Na + -activated K + channel known as Slo2.2 or SLACK. The objectives of this study were to perform the clinical and genetic characterization of the proband and his family and to examine the functional consequence of the Kir4.1 mutation. The mutant and wild-type KCNJ10 constructs were generated and heterologously expressed in Xenopus laevis oocytes, and whole cell K + currents were measured using the two-electrode voltage-clamp technique. The KCNJ10 mutation c.652C>T resulted in a p.L218F substitution at a highly conserved residue site. Wild-type KCNJ10 expression yielded robust Kir current, whereas currents from oocytes expressing the mutation were reduced, remarkably. Western Blot analysis revealed reduced protein expression by the mutation. Kir5.1 subunits display selective heteromultimerization with Kir4.1 constituting channels with unique kinetics. The effect of the mutation on Kir4.1/5.1 channel activity was twofold: a reduction in current amplitudes and an increase in the pH-dependent inhibition. We thus report a novel loss-of-function mutation in Kir4.1 found in a patient with a coexisting mutation in SLACK channels that results in a fatal disease. NEW & NOTEWORTHY We present and characterize a novel mutation in KCNJ10 Unlike previously reported EAST/SeSAME patients, our patient was heterozygous, and contrary to previous studies, mimicking the heterozygous state by coexpression resulted in loss of channel function. We report in the same patient co-occurrence of a KCNT1 mutation resulting in a more severe phenotype. This study provides new insights into the

    Fukuyama congenital muscular dystrophy (FCMD) is the second most common form of muscular dystrophy in Japan and is peculiarly associated with brain anomalies such as micropolygyria. Since these anomalies are preferentially observed on the brain surface, it is difficult to identify them by either X-ray CT or conventional MRI. In addition, FCMD has an atypical (mild) form in which the patients are capable of walking. In such cases, clinical differential diagnosis from Duchenne muscular dystrophy with severe mental retardation (DMD-MR) is not necessarily easy. We analyzed the brain-surface structures of 4 typical FCMD cases. 1 atypical FCMD case, 4 DMD-MR cases, and 1 undiagnosed case using a method of 3-dimensional (3-D) brain-surface MR imaging; we then compared the results with dystrophin immuno-stainings of the biopsied skeletal muscles. In both typical and atypical FCMD cases, micropolygyria could be clearly demonstrated, with individual variations. The 3-D images were verified by neuropathology. Of the 4 DMD-MR cases, 3 cases showed no gyral abnormality. However, in 1 DMD-MR case the diagnosis was corrected to atypical FCMD because of micropolygyria found on 3-D MRI. The one undiangosed case was diagnosed as DMD-MR on the basis of 3-D MRI. There was a good correspondence between the results of the 3-D imaging and the dystrophin test. Recently, some FCMD cases with a complete deficiency of dystrophin have been reported. Therefore, the detection of brain anomalies is important for the precise diagnosis of FCMD; the present method is considered effective for this purpose. (author).

    To provide an initial assessment of the safety of a recombinant adeno-associated virus vector expressing RPE65 (rAAV2-CB-hRPE65) in adults and children with retinal degeneration caused by RPE65 mutations. Nonrandomized, multicenter clinical trial. Eight adults and 4 children, 6 to 39 years of age, with Leber congenital amaurosis (LCA) or severe early-childhood-onset retinal degeneration (SECORD). Patients received a subretinal injection of rAAV2-CB-hRPE65 in the poorer-seeing eye, at either of 2 dose levels, and were followed up for 2 years after treatment. The primary safety measures were ocular and nonocular adverse events. Exploratory efficacy measures included changes in best-corrected visual acuity (BCVA), static perimetry central 30° visual field hill of vision (V30) and total visual field hill of vision (VTOT), kinetic perimetry visual field area, and responses to a quality-of-life questionnaire. All patients tolerated subretinal injections and there were no treatment-related serious adverse events. Common adverse events were those associated with the surgical procedure and included subconjunctival hemorrhage in 8 patients and ocular hyperemia in 5 patients. In the treated eye, BCVA increased in 5 patients, V30 increased in 6 patients, VTOT increased in 5 patients, and kinetic visual field area improved in 3 patients. One subject showed a decrease in BCVA and 2 patients showed a decrease in kinetic visual field area. Treatment with rAAV2-CB-hRPE65 was not associated with serious adverse events, and improvement in 1 or more measures of visual function was observed in 9 of 12 patients. The greatest improvements in visual acuity were observed in younger patients with better baseline visual acuity. Evaluation of more patients and a longer duration of follow-up will be needed to determine the rate of uncommon or rare side effects or safety concerns.

    The relative importance of congenital malformations as a cause of death in the first year of life is increasing along with the control of preventable causes of perinatal mortality. To identify risk factors for congenital malformations. Retrospective case-control study of births registered in the database of The Latin American Collaborative Study of Congenital Malformations (ECLAMC), in the period 2001-2010. Birth weight and gestational age were significantly lower in cases than controls, behaving as risk factors and associated with a greater severity of congenital malformations. The risk and severity of congenital malformations increased along with mother's age. Fetal growth retardation, a history of congenital malformations in the family, physical factors and acute illnesses of the mother in the first trimester of pregnancy were also significant risk factors for congenital malformations and their severity. The educational level of the mother was a protective factor for congenital malformations and their severity. Variables previously identified as risk factors for congenital malformations, were significantly related with the occurrence of congenital malformations and their severity.

    In contrast to the sophisticated music processing reported in the general population, individuals with congenital amusia show deficits in music perception and production. Congenital amusia occurs without brain damage, sensory or cognitive deficits, and has been suggested as a lifelong deficit with genetic origin. Even though recognized for a long time, this disorder has been systematically studied only relatively recently for its behavioral and neural correlates. The currently most investigated hypothesis about the underlying deficits concerns the pitch dimension, notably with impaired pitch discrimination and memory. Anatomic and functional investigations of pitch processing revealed that the amusic brain presents abnormalities in the auditory and inferior frontal cortices, associated with decreased connectivity between these structures. The deficit also impairs processing of pitch in speech material and processing of the time dimension in music for some of the amusic individuals, but does not seem to affect spatial processing. Some studies suggest at least partial dissociation in the disorder between perception and production. Recent studies revealed spared implicit pitch perception in congenital amusia, supporting the power of implicit cognition in the music domain. Current challenges consist in defining different subtypes of congenital amusia as well as developing rehabilitation programs for this "musical handicap." © 2015 Elsevier B.V. All rights reserved.

  3. Electroshock weapons can be lethal!

    2008-03-01

    Electroshock weapons (EWs)-stun guns, tasers, riot shields-are electroconductive devices designed to safely incapacitate healthy men neuromuscularly, so they are called nonlethal or less-lethal. EW firms seeking large nonmilitary markets targeted law enforcement and corrections personnel, who began using EWs in prisons/jails and on public patrol in 1980 in the USA. This shifted the EW-shocked population from healthy soldiers to a heterogeneous mix of both sexes, ages 6-92, in a wide variety of health conditions! An EW operates by disrupting normal physiological processes, producing transient effects in healthy people. But if a person's health is sufficiently compromised, the margin of safety can be lost, resulting in death or permanent health problems. 325 people have died after EW shock since 1980. Did the EW cause these deaths? Evidence indicates that EWs do play a causal role in most such deaths. EWs can be lethal for people in diabetic shock^1 (hypoglycemia), which may be why Robert Dziekanski-a Polish immigrant to Canada-died so quickly after he was tasered at Vancouver Airport: not having eaten for over 10 hours, he likely was severely hypoglycemic. The EW death rate in North America is 30 times higher than need be, because EW users have not been properly trained to use EWs on a heterogeneous population safely! ^1J.

    2015-06-01

    Full Text Available Noonan syndrome is a relatively common and heterogeneous genetic disorder, associated with congenital heart defect in about 50% of the cases. If the defect is not severe, life expectancy is normal. We report a case of Noonan syndrome in a preterm infant with hypertrophic cardiomyopathy and lethal outcome associated to acute respiratory distress syndrome caused by Adenovirus pneumonia. A novel mutation in the RAF1 gene was identified: c.782C>G (p.Pro261Arg in heterozygosity, not described previously in the literature. Consequently, the common clinical course in this mutation and its respective contribution to the early fatal outcome is unknown. No conclusion can be established regarding genotype/phenotype correlation.

    Diplopodia, or duplicated foot, is a rare congenital anomaly. It differs from polydactyly in that supernumerary metatarsal and tarsal bones are present as well as extra digits. Only a few cases of this anomaly have been reported in the literature to date. We present a newborn male without intrauterine teratogen exposure who was born with a duplicate foot of the left lower extremity and imperforate anus. (orig.)

  8. Congenital toxoplasmosis.

    Kieffer, François; Wallon, Martine

    2013-01-01

    Congenital toxoplasmosis results from the transplacental transmission of the parasite Toxoplasma gondii after a maternal infection acquired in pregnancy. Prevalence of congenital infection ranges from 0.1 to 0.3 per 1000 live births. The maternal-fetal transmission rate increases with gestational age at maternal seroconversion, from less than 15% at 13 weeks of gestation to over 70% at 36 weeks. Conversely, the later the maternal infection, the lower the risk of symptomatic congenital infection (infections acquired during the third trimester are most often asymptomatic at birth). Prenatal diagnosis is currently performed by PCR analysis in amniotic fluid. Antenatal management and treatment vary considerably among countries. In some European countries, maternal infections are detected through serological screening allowing a prompt treatment with spiramycin, which is expected to reduce the risk of vertical transmission. If PCR analysis in amniotic fluid is positive or if maternal infection was acquired in the third trimester of pregnancy, a combination with pyrimethamine and sulphonamide is given until delivery. Benefits of antenatal treatments remain controversial. Infected newborns are prescribed pyrimethamine and sulphonamide for 12 months. Despite antenatal and postnatal treatment, chorioretinitis can occur at any age (prevalence>20% at 10 years of age): long-term ophthalmological follow-up remains necessary.

    Congenital heart malformations are among the most common congenital malformations. Congenital heart malformations occur due to genetic and environmental factors during embryonic morphogenesis period of the heart. About 25% of these malformations are severe, requiring intervention immediately after birth or in infancy. Abnormalities of structure and function of the heart and great vessels are the consequence of teratogenic factors occurring between day 19 and 45 of gestation. (Yagel et al...

    1983-01-01

    In recent years, marked increase in incidence of congenital syphilis has occurred throughout the world due to changes in social norms and development of penicillin-resistant strains. Early diagnosis plays an important role in congenital syphilis as the clinical manifestations may simulate many other conditions in the paediatric age group. The authors analyzed 52 cases of congenital syphilis admitted to the department of paediatrics, Chosun University Hospital, clinically and radiologically. Among them, 18 cases were born in this hospital and 34 cases were admitted from OPD, during the period of 8 years from January, 1975 to December, 1982. The results obtained were as follows; 1. In 28 of 34 cases (82%), the first clinical manifestations were below the age of 3 months. 2. Among the 52 cases, a male predominance was observed with a male to female ratio of 2 : 1. 3. The serologic test (VDRL) of the 52 studied cases showed reactive response in 49 cases (94%), and that of syphilitic mothers except 6 cases, reactive in all studied cases. 4. The major manifestations of the 52 cases were bone tenderness (12%) and swelling of the joints (7%) in skeletal system, hepatosplenomegaly (79%) and skin lesions (73%) in extraskeletal one. 5. The radiological skeletal changes were detected in 45 of 52 cases (87%), and the commonest findings were detected in 45 of 52 cases (87%), and the commonest findings were metaphysitis (83%) and periostitis (81%). The most characteristic type of metaphysitis were transverse trophic line (74%) and zone of rarefaction (65%). 6. The commonest bones to be affected were growing metaphyses of the long bones, particulary about the wrist and the knee. The order of frequency were radius (80%), uina (80%), tibia (77%), femur (69%) and humerus (40%)

  13. Suicide Lethality: A Concept Analysis.

    DeBastiani, Summer; De Santis, Joseph P

    2018-02-01

    Suicide is a significant health problem internationally. Those who complete suicide may have different behaviors and risk factors than those who attempt a non-fatal suicide. The purpose of this article is to analyze the concept of suicide lethality and propose a clear definition of the concept through the identification of antecedents, attributes, and consequences. A literature search for articles published in the English language between 1970 and 2016 was conducted using MEDLINE, the Cochrane Library, Pubmed, Psychlit, Ovid, PsycINFO, and Proquest. The bibliographies of all included studies were also reviewed to identify additional relevant citations. A concept analysis was conducted on the literature findings using six stages of Walker and Avant's method. The concept analysis differentiated between suicide, lethality, suicidal behavior, and suicide lethality. Presence of a suicide plan or a written suicide note was not found to be associated with the majority of completed suicides included in the definition of suicide lethality. There are a few scales that measure the lethality of a suicide attempt, but none that attempt to measure the concept of suicide lethality as described in this analysis. Clarifying the concept of suicide lethality encourages awareness of the possibility of different suicidal behaviors associated with different suicide outcomes and will inform the development of future nursing interventions. A clearer definition of the concept of suicide lethality will guide clinical practice, research, and policy development aimed at suicide prevention.

    Congenital hypothyroidism is a clinical condition characterized by lack of thyroid hormone because of thyroid gland developmental and thyroid hormone biosynthesis disorders. The most common cause of permanent hypothyroidism is congenital factors. Prompt diagnosis is critical. However, overt signs of hypothyroidism are rarely present at birth, and 95% of affected babies are asymptomatic. Hypoxemia, apnea, acidosis, increased intracranial pressure, vagal stimulus and central nerve system abnormalities represent the most common causes of bradycardia in the neonate. Bradycardia associated with congenital hypothyroidism is very rare. In this paper, a case of severe congenital hypothyroidism, induced by maternal blocker antibodies, who presented with bradycardia, is reported. (author)

  17. The heart: Congenital disease

    Higgins, C.B.

    1987-01-01

    The most important diagnostic requirement in congenital heart disease (CHD) is definition of cardiovascular pathoanatomy. The considerable success in operative correction of even the most complex anomalies in recent years compels ever increasing precision in preoperative demonstration of these anomalies. Early experience with magnetic resonance imaging (MRI) at several institutions indicated that this modality is an effective noninvasive technique for evaluation of CHD. Indeed, MRI seems to have some advantage over other techniques, including angiography, for definitive diagnosis of congenital anomalies of the heart and great arteries and veins. The absence of ionizing radiation and contrast medium in MRI is an additional advantage; the former is particularly important for children, who, up to this time, have frequently been subjected to enormous radiation burdens from multiple cineangiograms during initial diagnosis and follow-up. This chapter describes the MRI appearance of cardiovascular anatomy im the segmental fashion proposed for analysis of complex CHD. Likewise, MRI demonstration of congenital cardiovascular lesions is organized into abnormalities situated at the four segmental cardiovascular levels: great vessels, atria, ventricles, and visceroatrial relationship. The role of MRI in evaluation of complex ventricular anomalies such as single ventricle and thoracic aortic abnormalities is specifically described

    For most people, music, like language, is acquired effortlessly in early life. But a few percent of the population have lifelong difficulties in the perception and production of music. In this chapter we discuss psycho-acoustic and behavioral studies that have attempted to delineate the nature of the auditory perceptual deficits in this group and consider whether these difficulties extend outside the musical domain. Finally, we review structural imaging studies in this group which point to subtle anomalies in temporal and frontal areas. We suggest that amusia can be considered a disorder of neural development, which has relatively specific consequences at the behavioral level. Studies of congenital amusia provide a unique window on the neurocognitive architecture of music processing. Copyright © 2013 Elsevier B.V. All rights reserved.

    Nance-Horan syndrome (NHS) is an X-linked disorder characterized by congenital cataracts, dental anomalies, dysmorphic features, and, in some cases, mental retardation. NHS has been mapped to a 1.3-Mb interval on Xp22.13. We have confirmed the same localization in the original, extended Australian family with NHS and have identified protein-truncating mutations in a novel gene, which we have called "NHS," in five families. The NHS gene encompasses approximately 650 kb of genomic DNA, coding for a 1,630-amino acid putative nuclear protein. NHS orthologs were found in other vertebrates, but no sequence similarity to known genes was identified. The murine developmental expression profile of the NHS gene was studied using in situ hybridization and a mouse line containing a lacZ reporter-gene insertion in the Nhs locus. We found a complex pattern of temporally and spatially regulated expression, which, together with the pleiotropic features of NHS, suggests that this gene has key functions in the regulation of eye, tooth, brain, and craniofacial development.

    In congenital Factor (F) VII deficiency bleeding phenotype and intrinsic FVII activity levels don't always correlate. Patients with FVII activity levels <30% appear to have a higher bleeding propensity, but bleeding can also occur at higher FVII activity levels. Reasons for bleeding at higher FVII activity levels are unknown, and it remains challenging to manage such patients clinically. A 19year old male with spontaneous intracranial hemorrhage and FVII activity levels of 44%, requiring emergent surgical intervention and a strategy for FVII replacement. Genotyping showed the rare heterozygous FVII 9729del4 mutation. Bleed evacuation was complicated by epidural abscess requiring craniectomy, bone graft procedures, and prolonged administration of recombinant human (rh) activated FVII (FVIIa). The patient recovered without neurological deficits, and remains on prophylactic low dose treatment with rhFVIIa in relation to risky athletic activities. For clinicians, it is important to recognize that effects of rhFVIIa within these pathways are independent of its contribution to blood clot formation and cannot be assessed by clotting assays. Reduced FVII levels should therefore not be dismissed, as even a mild reduction may result in spontaneous bleeding. Treatment of mild FVII deficiency requires a careful case-by-case approach, based on the clinical scenario. Copyright © 2015 Elsevier Inc. All rights reserved.

    The aim of this study was to describe whether the prophylactic use of a cervical pessary decreases the rate of premature birth in congenital diaphragmatic hernia (CDH) fetuses treated with fetoscopic tracheal occlusion (FETO). The study concerns a consecutive series of cases with CDH and FETO and a group of CDH without FETO. In a subgroup of the FETO group, a prophylactic cervical pessary was inserted the day following the procedure. Gestational age (GA) at birth was the primary outcome. Fifty-nine fetuses with FETO and 47 expectantly managed were included. The last 15 FETO had a cervical pessary inserted. The median GA at delivery in the FETO group with pessary was 35.1 weeks and was not different from that in the FETO group without a pessary (34.3 weeks; p = 0.28) but was below that in the expectantly managed group (38.3 weeks; p cervical pessary does not prolong gestation of CDH fetuses treated with FETO. © 2015 John Wiley & Sons, Ltd. © 2015 John Wiley & Sons, Ltd.

    Congenital diaphragmatic hernia is associated with cardiovascular malformation. Many prognostic factors have been identified for isolated congenital diaphragmatic hernia; however, reports of concurrent congenital diaphragmatic hernia and cardiovascular malformation in infants are limited. This study evaluated congenital diaphragmatic hernia associated with cardiovascular malformation in infants. Factors associated with prognosis for patients were also identified. This retrospective cohort study was based on a Japanese survey of congenital diaphragmatic hernia patients between 2006 and 2010. Frequency and outcome of cardiovascular malformation among infants with congenital diaphragmatic hernia were examined. Severity of congenital diaphragmatic hernia and cardiovascular malformation were compared as predictors of mortality and morbidity. Cardiovascular malformation was identified in 76 (12.3%) of 614 infants with congenital diaphragmatic hernia. Mild cardiovascular malformation was detected in 19 (33.9%) and severe cardiovascular malformation in 37 (66.1%). Their overall survival rate at discharge was 46.4%, and the survival rate without morbidity was 23.2%. Mortality and morbidity at discharge were more strongly associated with severity of cardiovascular malformation (adjusted OR 7.69, 95%CI 1.96-30.27; adjusted OR 7.93, 95%CI 1.76-35.79, respectively) than with severity of congenital diaphragmatic hernia. The prognosis for infants with both congenital diaphragmatic hernia and cardiovascular malformation remains poor. Severity of cardiovascular malformation is a more important predictive factor for mortality and morbidity than severity of congenital diaphragmatic hernia. © 2013 The Authors.

    To review the association between congenital heart defects and extracardiac malformations. Scientific articles were searched in the Medline, Lilacs, and SciELO databases, using the descriptors "congenital heart disease," "congenital heart defects," "congenital cardiac malformations," "extracardiac defects," and "extracardiac malformations." All case series that specifically explored the association between congenital heart defects and extracardiac malformations were included. Congenital heart diseases are responsible for about 40% of birth defects, being one of the most common and severe malformations. Extracardiac malformations are observed in 7 to 50% of the patients with congenital heart disease, bringing a greater risk of comorbidity and mortality and increasing the risks related to heart surgery. Different studies have attempted to assess the presence of extracardiac abnormalities in patients with congenital heart disease. Among the changes described, those of the urinary tract are more often reported. However, no study has evaluated all patients in the same way. Extracardiac abnormalities are frequent among patients with congenital heart disease, and patients with these alterations may present an increased risk of morbimortality. Therefore, some authors have been discussing the importance and cost-effectiveness of screening these children for other malformations by complementary exams.

    This is a case report of a 32-year-old man exposed to a total body dose of 14.5 Gy γ-radiation in a lethal 60 Co-source irradiation accident in 2008 in China. Frequent nausea, vomiting and marked neutropenia and lymphopenia were observed from 30 min to 45 h after exposure. HLA-mismatched peripheral blood stem cell transplantation combined with infusion of mesenchymal stem cells was used at Day 7. Rapid hematopoietic recovery, stable donor engraftment and healing of radioactive skin ulceration were achieved during Days 18-36. The patient finally developed intestinal obstruction and died of multi-organ failure on Day 62, although intestinal obstruction was successfully released by emergency bowel resection. (author)

    Lethal multiple pterygium syndrome is a rare inherited disorder. Previous reports suggest that the diagnosis may be based on prenatal sonographic demonstration of severe limb flexion, absence of fetal motion, and a large cystic hygroma in the second and third trimesters. We present the sonographic features and postmortem features of a fetus with lethal multiple pterygium syndrome at 13 weeks of gestation, which shows that the condition can possibly be diagnosed in the first trimester of pregnancy.

  7. [Congenital hypothyroidism].

    Science.gov (United States)

    Castilla Peón, María Fernanda

    Congenital hypothyroidism (CH) is a cause of preventable mental retardation; therefore, timely diagnosis and treatment by the primary care physician is very important. CH screening must be performed between the second and fifth days of life with capillary blood done with a heel prick and must be confirmed by measurement of thyroid hormones in venous blood. The most common cause of CH is thyroid dysgenesis, which may be identified by a thyroid scan carried out before initiating treatment. Treatment should be with levothyroxine (10-15μg/kg/day) and should not be delayed or suspended during the first 3 years of life due to the deleterious effect on neurodevelopment in case of low thyroid hormones during this time. Preterm or sick infants or those with Down syndrome require special consideration. This article provides diagnostic and therapeutic algorithms for CH.

    During 1986 the authors came across two cases of brain abscess among children with congenital heart disease followed at the Pediatric Cardiology Service and decided to evaluate their global experience on the subject. In a retrospective study of 860 infants and children with cyanotic congenital heart disease and final diagnosis, there were four cases complicated with brain abscess. The following items were evaluated: prevalence of the complication, type of congenital heart disease, date and age at the diagnosis of brain abscess, diagnostic methods, neurosurgical treatment and results. The main findings were: all patients were above two years of age and had noncorrected cyanotic congenital heart disease belonging to the classic high risk group; the first two cases had been treated in other institutions and only scanty information was available; two recent cases had early diagnosis on CAT scan followed by neurosurgical treatment. All children survived. brain abscess is a rare but severe complication occurring in patients with noncorrected cyanotic congenital heart disease above two years of age; whenever prevention turns impossible, early diagnosis and treatment provide good short term and long term results. A multidisciplinar approach with full cooperation is advocated.

    Congenital hydrocephalus is an important birth defect, the genetics of which remains incompletely understood. To date, only 4 genes are known to cause Mendelian diseases in which congenital hydrocephalus is the main or sole clinical feature, 2 X-linked (L1CAM and AP1S2) and 2 autosomal recessive (CCDC88C and MPDZ). In this study, we aimed to determine the genetic etiology of familial congenital hydrocephalus with the assumption that these cases represent Mendelian forms of the disease. Exome sequencing combined, where applicable, with positional mapping. We identified a likely causal mutation in the majority of these families (21 of 27, 78%), spanning 16 genes, none of which is X-linked. Ciliopathies and dystroglycanopathies were the most common etiologies of congenital hydrocephalus in our cohort (19% and 26%, respectively). In 1 family with 4 affected members, we identified a homozygous truncating variant in EML1, which we propose as a novel cause of congenital hydrocephalus in addition to its suggested role in cortical malformation. Similarly, we show that recessive mutations in WDR81, previously linked to cerebellar ataxia, mental retardation, and disequilibrium syndrome 2, cause severe congenital hydrocephalus. Furthermore, we confirm the previously reported candidacy of MPDZ by presenting a phenotypic spectrum of congenital hydrocephalus associated with 5 recessive alleles. Our study highlights the importance of recessive mutations in familial congenital hydrocephalus and expands the locus heterogeneity of this condition.

    One way to address the growing problem of antimicrobial resistance is to revive old compounds that may have intrinsic lethal activity that is obscured by protective factors. Bicyclomycin is an old inhibitor of the Rho transcription terminator that by itself shows little rapid lethal activity. However, bicyclomycin participates in bacteriostatic synergy, which raises the possibility that conditions for lethal synergy may exist, perhaps through a suppression of protective factors. Bicyclomycin was combined with bacteriostatic inhibitors of gene expression, and bactericidal activity was measured with several cultured Gram-negative pathogens. When used alone, bicyclomycin failed to rapidly kill growing cultures of Escherichia coli; however, the additional presence of bacteriostatic concentrations of tetracycline, chloramphenicol or rifampicin led to rapid killing. Four other pathogen species, Acinetobacter baumannii, Klebsiella pneumoniae, Salmonella enterica serotype Typhimurium and Shigella dysenteriae, also exhibited enhanced killing when bicyclomycin was combined with tetracycline or rifampicin. This lethal synergy was achieved at low concentrations (slightly above the MIC) for all agents tested in combinations. Follow-up work with E. coli indicated that lethal synergy arose from a blockage of transcription elongation. Moreover, lethal synergy was reduced when bicyclomycin was added 60 min before tetracycline, suggesting that bicyclomycin induces a protective factor. The action of bicyclomycin illustrates the potential present in a largely abandoned antibacterial agent; it exhibits lethal synergy when coadministered with known, bacteriostatic inhibitors of gene expression. The identification of protective factors, which are currently uncharacterized, may reveal new ways to promote the lethal action of some old antibiotics. © The Author 2014.

    Gender influences the clinical presentation and the management of some acquired cardiovascular diseases, such as coronary artery disease, resulting in different outcomes. Differences between women and men are also noticed in congenital heart disease. They are mainly related to the prevalence and severity of some congenital heart defects at birth, and in adulthood to the prognosis, incidence of Eisenmenger syndrome and risks of pregnancy. The role of gender on the risk of operative mortality of congenital heart surgery remains debated. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    In 1985, we briefly reported infant sisters with a unique, lethal, autosomal recessive disorder designated congenital sclerosing osteomalacia with cerebral calcification. In 1986, this condition was entered into Mendelian Inheritance In Man (MIM) as osteomalacia, sclerosing, with cerebral calcification (MIM 259660). However, no attestations followed. Instead, in 1989 Raine and colleagues published an affected neonate considering unprecedented the striking clinical and radiographic features. In 1992, "Raine syndrome" entered MIM formally as osteosclerotic bone dysplasia, lethal (MIM #259775). In 2007, the etiology emerged as loss-of-function mutation of FAM20C that encodes family with sequence similarity 20, member C. FAM20C is highly expressed in embryonic calcified tissues and encodes a kinase (dentin matrix protein 4) for most of the secreted phosphoproteome including FGF23, osteopontin, and other regulators of skeletal mineralization. Herein, we detail the clinical, radiological, biochemical, histopathological, and FAM20C findings of our patients. Following premortem tetracycline labeling, the proposita's non-decalcified skeletal histopathology after autopsy indicated no rickets but documented severe osteomalacia. Archival DNA revealed the sisters were compound heterozygotes for a unique missense mutation and a novel deletion in FAM20C. Individuals heterozygous for the missense mutation seemed to prematurely fuse their metopic suture and develop a metopic ridge sometimes including trigonocephaly. Our findings clarify FAM20C's role in hard tissue formation and mineralization, and show that Raine syndrome is congenital sclerosing osteomalacia with cerebral calcification. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and Mineral Research.

  2. Polymicrogyria and Congenital Parvovirus B19 Infection

    2011-12-01

    Full Text Available Fetal parvovirus B19 infection causes anemia, hydrops, and pregnancy loss but is generally not considered teratogenic. Nevertheless, disturbances of neuronal migration have been described with congenital parvovirus infection. We evaluated a term infant with congenital parvovirus disease and polymicrogyria. We compared this case with four other reports of central nervous system disease after birth to parvovirus-infected mothers. After an extensive diagnostic evaluation, this infant was found to have congenital parvovirus disease with severe anemia and nonimmune hydrops as well as extensive polymicrogyria. Although rare, this report and literature review suggest that parvovirus B19 has the potential to disrupt normal neurodevelopment. We suggest that infants with severe congenital parvovirus infection have close developmental surveillance and if symptomatic undergo neuroimaging to assess for disorders of neuromigration.

    2018-03-01

    Congenital scoliosis is a failure of vertebral formation, segmentation, or a combination of the 2 arising from abnormal vertebral development during weeks 4 to 6 of gestation. The associated spinal deformity can be of varying severity and result in a stable or progressive deformity based on the type and location of the anomalous vertebra(e). Bracing for congenital scoliosis is rarely indicated, while recent reports have demonstrated the utility of serial derotational casting for longer curves with multiple anomalous vertebrae as an effective "time buying strategy" to delay the need for surgery. Earlier hemivertebra excision and short-segment posterior spinal fusion have been advocated to prevent future curve progression of the deformity and/or the development of large compensatory curves. It has been shown in recent long-term follow-up studies that growth rates of the vertebral body and spinal canal are not as dramatically affected by pedicle screw instrumentation at a young age as once thought. Growth friendly surgery with either spine-based or rib-based anchors has demonstrated good results with curve correction while maintaining spinal growth. Rib-based anchors are typically more commonly indicated in the setting of chest wall abnormalities and/or when spinal anatomy precludes placement of spinal instrumentation. Recently, magnetically controlled growing rods have shown promising results in several studies that include a small subset of congenital scoliosis cases. A literature search was performed to identify existing studies related to the treatment of congenital scoliosis published from January 1, 2005 to June 1, 2016. Databases included PubMed, Medline, and the Cochrane Library. The search was limited to English articles and yielded 36 papers. This project was initiated by the Pediatric Orthopaedic Society of North America Publications Committee and was reviewed and approved by the Pediatric Orthopaedic Society of North America Presidential Line.

    To study the neuropathologic changes and CT manifestations in congenital TORCH infection of the brain. Analysis of 7 cases of congenital TORCH infection of the neonates and infants demonstrated by serum examination was performed. There were congenital toxoplasmosis 3 cases, congenital syncytial virus infection 1 case, congenital rubella virus infection 1 case, congenital cytomegalovirus infection 2 cases, and congenital herpes simplex virus infection 1 case. Cerebral hypoplasia, ventricular dilatation or hydrocephalus, subependymal and parenchymal calcifications, microcephalic focal cortical migration anomalies, schizencephaly polymicrogyria, et al, were demonstrated by CT with congenital TORCH infection. The earlier the infection, the more severe the brain developmental anomalies. The extent and appearance of calcification in brain were related to the degree, extent and course of TORCH infection. Basal ganglia calcification of unknown cause in infant was suggestive of congenital TORCH infection. Typical CT manifestations together with clinical picture may suggest congenital TORCH infection, while serological test can be diagnostic

A great variety of inner ear anomalies was detected, but rarely were these characteristic of a particular clinical entity. The most common finding was the Mondini malformation or one of its variants. Isolated dysplasia of the internal auditory canal or the vestibular aqueduct may be responsible for sensorineural hearing loss in some patients. Patients with microtia may also have severe inner ear abnormalities despite the fact that the outer and inner ears develop embryologically from completely separate systems

  8. Congenital anomalies: Impact of prenatal diagnosis on mode of delivery.

    Dempsey, M A

    2010-03-01

    An important aspect of prenatal diagnosis is the avoidance of emergency caesarean delivery (CD) where the abnormality is considered lethal and the infant will not survive. A consecutive cohort of 211,163 women delivered of infants weighing 500 grams or more in three tertiary referral centers from 01\\/95 to 12\\/04, was analyzed for perinatal death attributed to congenital malformations. In the group that died in the neonatal period, the emergency CD rate was significantly lower where anomaly was detected versus undetected (17.5% versus 31%). Further, in contrast to undiagnosed anomalies, the indication for emergency CD was more often maternal in the diagnosed group (42% versus 19%, p=0.019). When a diagnosis of lethal congenital anomaly has been made in the prenatal period, the reduction in the emergency CD rate by almost half in this study supports a pivotal role for prenatal diagnosis in optimizing maternal care.

  14. Mutations in the ELA2 gene encoding neutrophil elastase are present in most patients with sporadic severe congenital neutropenia but only in some patients with the familial form of the disease.

    2001-11-01

    Severe congenital neutropenia (SCN) was originally described as an autosomal recessive disorder. Subsequently, autosomal dominant and sporadic forms of the disease have been recognized. All forms are manifest by persistent severe neutropenia and recurrent bacterial infection. In contrast, cyclical hematopoiesis is characterized by periodic neutropenia inter-spaced with (near) normal neutrophil counts. Recently, linkage analysis on 13 affected pedigrees identified chromosome 19p13.3 as the likely position for mutations in cyclical hematopoiesis. Heterozygous mutations in the ELA2 gene encoding neutrophil elastase were detected in all families studied. Further work also demonstrated mutations in ELA2 in sporadic and autosomal dominant SCN. However, all mutations described to date are heterozygous and thus appear to act in a dominant fashion, which is inconsistent with an autosomal recessive disease. Therefore, the current study investigated whether mutations in ELA2 could account for the disease phenotype in classical autosomal recessive SCN and in the sporadic and autosomal dominant types. All 5 exons of ELA2 and their flanking introns were studied in 18 patients (3 autosomal recessive, 5 autosomal dominant [from 3 kindreds], and 10 sporadic) using direct automated sequencing. No mutations were found in the autosomal recessive families. A point mutation was identified in 1 of 3 autosomal dominant families, and a base substitution was identified in 8 of 10 patients with the sporadic form, though 1 was subsequently shown to be a low-frequency polymorphism. These results suggest that mutations in ELA2 are not responsible for classical autosomal recessive Kostmann syndrome but provide further evidence for the role of ELA2 in SCN.

    2018-01-01

    The versatility offered by zebrafish (Danio rerio) makes it a powerful and an attractive vertebrate model in developmental toxicity and teratogenicity assays. Apart from the newly introduced chemicals as drugs, xenobiotics also induce abnormal developmental abnormalities and congenital malformations in living organisms. Over the recent decades, zebrafish embryo/larva has emerged as a potential tool to test teratogenicity potential of these chemicals. Zebrafish responds to compounds as mammals do as they share similarities in their development, metabolism, physiology, and signaling pathways with that of mammals. The methodology used by the different scientists varies enormously in the zebrafish embryotoxicity test. In this chapter, we present methods to assess lethality and malformations during zebrafish development. We propose two major malformations scoring systems: binomial and relative morphological scoring systems to assess the malformations in zebrafish embryos/larvae. Based on the scoring of the malformations, the test compound can be classified as a teratogen or a nonteratogen and its teratogenic potential is evaluated.

  1. Empirical complexities in the genetic foundations of lethal mutagenesis.

    Bull, James J; Joyce, Paul; Gladstone, Eric; Molineux, Ian J

    2013-10-01

    From population genetics theory, elevating the mutation rate of a large population should progressively reduce average fitness. If the fitness decline is large enough, the population will go extinct in a process known as lethal mutagenesis. Lethal mutagenesis has been endorsed in the virology literature as a promising approach to viral treatment, and several in vitro studies have forced viral extinction with high doses of mutagenic drugs. Yet only one empirical study has tested the genetic models underlying lethal mutagenesis, and the theory failed on even a qualitative level. Here we provide a new level of analysis of lethal mutagenesis by developing and evaluating models specifically tailored to empirical systems that may be used to test the theory. We first quantify a bias in the estimation of a critical parameter and consider whether that bias underlies the previously observed lack of concordance between theory and experiment. We then consider a seemingly ideal protocol that avoids this bias-mutagenesis of virions-but find that it is hampered by other problems. Finally, results that reveal difficulties in the mere interpretation of mutations assayed from double-strand genomes are derived. Our analyses expose unanticipated complexities in testing the theory. Nevertheless, the previous failure of the theory to predict experimental outcomes appears to reside in evolutionary mechanisms neglected by the theory (e.g., beneficial mutations) rather than from a mismatch between the empirical setup and model assumptions. This interpretation raises the specter that naive attempts at lethal mutagenesis may augment adaptation rather than retard it.

    Deletion mutations have been extremely useful in initiating the functional and molecular dissections of regions of the mouse genome. For the d-se and c regions, for example, it was observed that radiation mutations carrying lethal factors separable, by complementation analysis, from the primary d, se, or c mutation itself, could often be associated at both the genetic and molecular levels with multilocus chromosomal deletions. Since many of the Oak Ridge Sld mutations arose in radiation mutagenesis experiments, a substantial number may carry chromosomal deletions that involve the Sl locus in chromosome 10. Because of the great value of deletion mutations for the genetic and molecular analysis of chromosomal regions and complex genetic loci, they have initiated a series of experiments designed to test whether radiation-induced Sld mutations carry other lethal factors, in addition to the lethality caused by severe alleles of the Sl locus itself, as one prescreen for identifying Sld's that are caused by deletions

  4. The Effects of Anthrax Lethal Toxin on Host Barrier Function

    Full Text Available The pathological actions of anthrax toxin require the activities of its edema factor (EF and lethal factor (LF enzyme components, which gain intracellular access via its receptor-binding component, protective antigen (PA. LF is a metalloproteinase with specificity for selected mitogen-activated protein kinase kinases (MKKs, but its activity is not directly lethal to many types of primary and transformed cells in vitro. Nevertheless, in vivo treatment of several animal species with the combination of LF and PA (termed lethal toxin or LT leads to morbidity and mortality, suggesting that LT-dependent toxicity is mediated by cellular interactions between host cells. Decades of research have revealed that a central hallmark of this toxicity is the disruption of key cellular barriers required to maintain homeostasis. This review will focus on the current understanding of the effects of LT on barrier function, highlighting recent progress in establishing the molecular mechanisms underlying these effects.

    The objectives of this review are to discuss the pathophysiology, clinical impact and treatment of major noncardiac anomalies, and prematurity in infants with congenital heart disease. MEDLINE and PubMed. Mortality risk is significantly higher in patients with congenital heart disease and associated anomalies compared with those in whom the heart defect occurs in isolation. Although most noncardiac structural anomalies do not require surgery in the neonatal period, several require surgery for survival. Management of such infants poses multiple challenges. Premature infants with congenital heart disease face challenges imposed by their immature organ systems, which are susceptible to injury or altered function by congenital heart disease and abnormal circulatory physiology independent of congenital heart disease. For optimal outcomes in premature infants or in infants with multiple congenital anomalies, a collaborative interdisciplinary approach is necessary.

    Congenital neutropenia is a heterogeneous bone marrow failure syndrome characterized by a maturation arrest of myelopoesis at the promyelocyte/myelocyte stage. Cyclic neutropenia (CyN) and severe congenital neutropenia (SCN) are two main forms of congenital neutropenia. Genetic analysis has shown that heterozygous mutations in the ELANE gene encoding the neutrophil elastase are the major cause of these disorders. We investigated the prevalence of ELANE mutations in a group of 16 patients from 14 families with congenital neutropenia. Five patients had typical manifestations of CyN, and 11 patients had SCN. Seven different heterozygous ELANE mutations were found, including four novel mutations. Copyright © 2011 Wiley-Liss, Inc.

    Simpson-Golabi Behmel syndrome (SGBS) is an X-linked disorder characterized by pre- and postnatal macrosomia, minor facial anomalies, and variable visceral, skeletal, and neurological abnormalities. Since its first description by Simpson et al., a wide clinical range of cases has been reported. There is great variability in severity, ranging from a mild form associated with long-term survival to an early lethal form with multiple congenital anomalies and severe mental retardation. In 8 reported families, affected individuals died in infancy. Here we present 4 maternally related, male cousins with a severe variant of SGBS. One of these males was aborted therapeutically at 19 weeks of gestation following the detection of multicystic kidneys on ultrasound. The 3 liveborn males were hydropic at birth with a combination of craniofacial anomalies including macrocephaly; apparently low-set, posteriorly angulated ears; hypertelorism; short, broad nose with anteverted nares; large mouth with thin upper vermilion border; prominent philtrum; high-arched or cleft palate; short neck; redundant skin; hypoplastic nails; skeletal defects involving upper and lower limbs; gastrointestinal and genitourinary anomalies. All 3 patients were hypotonic and neurologically impaired from birth. With the exception of a trilobate left lung in one patient, the cardiorespiratory system was structurally normal. All patients died within the first 8 weeks of life of multiple complications including pneumonia and sepsis. Two SGBS kindreds, with moderate expression of the condition, have been mapped to Xq27. It is not known whether severe, familiar cases, such as ours, are genetically distinct from and map to another locus. Final resolution of the genetic basis of the phenotypic variability in SGBS must await cloning and mutation analysis of the SGBS gene(s). 21 refs., 4 figs., 1 tab.

    Symmastia is defined as medial confluence of the breast. The term 'symmastia' is modified from Greek (syn meaning 'together', and mastos meaning 'breast') and was first presented by Spence et al. in 1983. Two forms of symmastia exist: an iatrogenic and a congenital version. Congenital symmastia...... is a rare condition in which web-like soft tissue traverses the sternum to connect the breasts medially. The literature on congenital symmastia is limited, few cases have been published, and knowledge about ideal treatment is still insufficient....

    We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

    Congenital toxoplasmosis is considered a rare but potentially severe infection. Prenatal education about congenital toxoplasmosis could be the most efficient and least harmful intervention, yet its effectiveness is uncertain. To assess the effects of prenatal education for preventing congenital toxoplasmosis. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2015), and reference lists of relevant papers, reviews and websites. Randomized and quasi-randomized controlled trials of all types of prenatal education on toxoplasmosis infection during pregnancy. Cluster-randomized trials were eligible for inclusion. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Two cluster-randomized controlled trials (RCTs) (involving a total of 5455 women) met the inclusion criteria. The two included trials measured the effectiveness of the intervention in different ways, which meant that meta-analysis of the results was not possible. The overall quality of the two studies, as assessed using the GRADE approach, was low, with high risk of detection and attrition bias in both included trials.One trial (432 women enrolled) conducted in Canada was judged of low methodological quality. This trial did not report on any of the review's pre-specified primary outcomes and the secondary outcomes reported results only as P values. Moreover, losses to follow-up were high (34%, 147 out of 432 women initially enrolled). The authors concluded that prenatal education can effectively change pregnant women's behavior as it increased pet, personal and food hygiene. The second trial conducted in France was also judged of low methodological quality. Losses to follow-up were also high (44.5%, 2233 out of 5023 women initially enrolled) and differential (40% in the intervention group and 52% in the control group). The authors concluded that prenatal education for congenital toxoplasmoses has a

    Full Text Available Long QT intervals in the ECG have long been associated with sudden cardiac death. The congenital long QT syndrome was first described in individuals with structurally normal hearts in 1957.1 Little was known about the significance of a short QT interval. In 1993, after analyzing 6693 consecutive Holter recordings Algra et al concluded that an increased risk of sudden death was present not only in patients with long QT interval, but also in patients with short QT interval (<400 ms.2 Because this was a retrospective analysis, further evaluation of the data was not possible. It was not until 2000 that a short-QT syndrome (SQTS was proposed as a new inherited clinical syndrome by Gussak et al.3 The initial report was of two siblings and their mother all of whom displayed persistently short QT interval. The youngest was a 17 year old female presenting with several episodes of paroxysmal atrial fibrillation requiring electrical cardioversion.3 Her QT interval measured 280 msec at a heart rate of 69. Her 21 year old brother displayed a QT interval of 272 msec at a heart rate of 58, whereas the 51 year old mother showed a QT of 260 msec at a heart rate of 74. The authors also noted similar ECG findings in another unrelated 37 year old patient associated with sudden cardiac death.

    The congenital nephrotic syndrome (CNS) is an uncommon disorder with onset of the nephrotic syndrome usually in the first three months of life. Several different diseases may cause the syndrome. These may be inherited, sporadic, acquired or part of a general malformation syndrome. The clinical course is marked by failure to thrive, recurrent life threatening bacterial infections, and early death from sepsis and/or uremia. A characteristic phenotype may be seen in children with CNS. The majority of reported cases of CNS are of the Finnish type (CNF). Although the role of the glomerular basement membrane has been emphasized as the barrier for retaining plasma proteins, recent studies have clearly shown that the slit diaphragm is the structure most likely to be the barrier in the glomerular capillary wall. The gene (NPHS1) was shown to encode a novel protein that was termed nephrin, due to its specific location in the kidney filter barrier, where it seems to form a highly organized filter structure. Nephrin is a transmembrane protein that probably forms the main building block of an isoporous zipper-like slit diaphragm filter structure. Defects in nephrin lead to the abnormal or absent slit diaphragm resulting in massive proteinuria and renal failure.

    2006-10-01

    Full Text Available Abstract Congenital pulmonary lymphangiectasia (PL is a rare developmental disorder involving the lung, and characterized by pulmonary subpleural, interlobar, perivascular and peribronchial lymphatic dilatation. The prevalence is unknown. PL presents at birth with severe respiratory distress, tachypnea and cyanosis, with a very high mortality rate at or within a few hours of birth. Most reported cases are sporadic and the etiology is not completely understood. It has been suggested that PL lymphatic channels of the fetal lung do not undergo the normal regression process at 20 weeks of gestation. Secondary PL may be caused by a cardiac lesion. The diagnostic approach includes complete family and obstetric history, conventional radiologic studies, ultrasound and magnetic resonance studies, lymphoscintigraphy, lung functionality tests, lung biopsy, bronchoscopy, and pleural effusion examination. During the prenatal period, all causes leading to hydrops fetalis should be considered in the diagnosis of PL. Fetal ultrasound evaluation plays a key role in the antenatal diagnosis of PL. At birth, mechanical ventilation and pleural drainage are nearly always necessary to obtain a favorable outcome of respiratory distress. Home supplemental oxygen therapy and symptomatic treatment of recurrent cough and wheeze are often necessary during childhood, sometimes associated with prolonged pleural drainage. Recent advances in intensive neonatal care have changed the previously nearly fatal outcome of PL at birth. Patients affected by PL who survive infancy, present medical problems which are characteristic of chronic lung disease.

    Tityus serrulatus (Ts) is the main scorpion species of medical importance in Brazil. Ts venom is composed of several compounds such as mucus, inorganic salts, lipids, amines, nucleotides, enzymes, kallikrein inhibitor, natriuretic peptide, proteins with high molecular mass, peptides, free amino acids and neurotoxins. Neurotoxins are considered the most responsible for the envenoming syndrome due to their pharmacological action on ion channels such as voltage-gated sodium (Nav) and potassium (Kv) channels. The major goal of this review is to present important advances in Ts envenoming research, correlating both the crude Ts venom and isolated toxins with alterations observed in all human systems. The most remarkable event lies in the Ts induced massive releasing of neurotransmitters influencing, directly or indirectly, the entire body. Ts venom proved to extremely affect nervous and muscular systems, to modulate the immune system, to induce cardiac disorders, to cause pulmonary edema, to decrease urinary flow and to alter endocrine, exocrine, reproductive, integumentary, skeletal and digestive functions. Therefore, Ts venom possesses toxins affecting all anatomic systems, making it a lethal cocktail. However, its low lethality may be due to the low venom mass injected, to the different venom compositions, the body characteristics and health conditions of the victim and the local of Ts sting. Furthermore, we also described the different treatments employed during envenoming cases. In particular, throughout the review, an effort will be made to provide information from an extensive documented studies concerning Ts venom in vitro, in animals and in humans (a total of 151 references).

    Schizencephaly (from the Greek meaning ''split brain''), is a term developed in the 1940s to explain symmetric clefts in the brain seen at autopsy in children with histories of severe neurologic defects. Use of the term has been expanded to include a variety of cerebral clefts. A review of the experience at Children's Memorial Hospital as well as case materials made available to the authors are presented, including CT, MR imaging, and US findings. Theories of etiology and pathogenesis of these congenital clefts, associated anomalies, and the spectrum of appearance of these clefts are discussed

    The proximal spinal muscular atrophies (PSMA), one of the most common forms of lower motor neuron disease in children, are characterized by progressive muscle weakness due to loss of anterior horn cells. All three autosomal recessive forms have been mapped to chromosome 5q11.2-11.3, implying an allelic association between these disorders. Recent evidence from our laboratories, as well as others, suggests that a distinct form of lethal neonatal spinal muscular atrophy, associated with early onset contractures, is determined by a gene on the X chromosome. We report our efforts in mapping this disease locus. Our original studies have focused on two unrelated multigenerational families with similar clinical presentations of severe hypotonia, muscle weakness, and a disease course similar to Werdnig Hoffman except for the additional finding of congenital or early onset contractures. Muscle biopsy and/or autopsy were indicative of anterior horn cell loss in affected males. Disease occurrence in each of the families was consistent with an X-linked recessive mode of inheritance. Subsequently, two additional families have been identified, as well as several sporadic male cases. Linkage analysis has been completed in one of these families using highly polymorphic repeats dispersed 10 cM on the X chromosome. Interpretation of results was achieved using an automated data acquisition program. Analysis of over 300 haplotypes generated using PCR-based DNA markers have identified two 16 cM regions on Xp with complete concordance to the disease phenotype. Our currents efforts are focused on the region surrounding the Kallman gene, in attempts to better define a candidate region, as well as analyze possible candidate genes within this region.

    1990-01-01

    Congenital urethral valve is the common cause of hydronephrosis in newborn infants and the most common cause of bladder outlet obstruction in male children. We reviewed and analysed radiological findings and associated anomalies of 16 cases of congenital urethral valve which were examined during the period from January 1985 to December 1989. The most frequent age was under one year old (56%). The main symptoms were urinary dribbing (37.5%), weak stream (25%) and urinary frequency and incontinence (25%). Anterior urethral valve (AUV) was 5 cases (31%) and posterior urethral valve (PUV) was 11 cases(69%), in which 10 cases were Type I and one case was Type III. Bladder wall thickening was seen in all cases and its severity was partly correlated with the degree of vesicoureteral reflux (VUR). VUR was observed in 12 cases (75%), and relatively severe in older age group. The degree of VUR was milder in AUV than PUV. Hydronephrosis was more severe in PUV than in anterior one, and its degree was correlated with the severity of VUR. Associated anomalies were ectopic urethral opening (2 cases), PDA (1 case), congenital megacolon (1 case) and patent urachus (1 case) in PUV. So early diagnosis and treatment of congenital urethral valve is essential to the prevention of renal damage

    Full Text Available Congenital lamellar ichthyosis is an autosomal recessive, heterogeneous disorder presenting at birth with generalized skin involvement. The most common ophthalmic manifestation noted is bilateral ectropion of the lower eyelids. A 1-month-old female neonate, the second born of a nonconsanguineous marriage, presented with 4 days' history of redness, discharge, and swelling in the right eye. There was severe right upper eyelid ectropion, conjunctival injection, chemosis, a subconjunctival mass on the temporal bulbar conjunctiva spontaneously draining pus and corneal haze. The anterior chamber, iris, lens and fundus appeared normal. Congenital lamellar ichthyosis was suspected because of scaling and excessive dryness of the entire body. The occurrence of a spontaneous subconjunctival abscess is not known in lamellar ichthyosis. We thus report the management of a rare case of unilateral upper eyelid ectropion, subconjunctival abscess with orbital cellulitis in congenital lamellar ichthyosis.

  11. Congenital malaria in China.

    Full Text Available BACKGROUND: Congenital malaria, in which infants are directly infected with malaria parasites from their mother prior to or during birth, is a potentially life-threatening condition that occurs at relatively low rates in malaria-endemic regions. It is recognized as a serious problem in Plasmodium falciparum-endemic sub-Saharan Africa, where recent data suggests that it is more common than previously believed. In such regions where malaria transmission is high, neonates may be protected from disease caused by congenital malaria through the transfer of maternal antibodies against the parasite. However, in low P. vivax-endemic regions, immunity to vivax malaria is low; thus, there is the likelihood that congenital vivax malaria poses a more significant threat to newborn health. Malaria had previously been a major parasitic disease in China, and congenital malaria case reports in Chinese offer valuable information for understanding the risks posed by congenital malaria to neonatal health. As most of the literature documenting congenital malaria cases in China are written in Chinese and therefore are not easily accessible to the global malaria research community, we have undertaken an extensive review of the Chinese literature on this subject. METHODS/PRINCIPAL FINDINGS: Here, we reviewed congenital malaria cases from three major searchable Chinese journal databases, concentrating on data from 1915 through 2011. Following extensive screening, a total of 104 cases of congenital malaria were identified. These cases were distributed mainly in the eastern, central, and southern regions of China, as well as in the low-lying region of southwest China. The dominant species was P. vivax (92.50%, reflecting the malaria parasite species distribution in China. The leading clinical presentation was fever, and other clinical presentations were anaemia, jaundice, paleness, diarrhoea, vomiting, and general weakness. With the exception of two cases, all patients

    Full Text Available Background: CMV is the most common agent that causes congenital virus infection. Only 10 % of infected children have symptomatic infection immediately after birth. Signs of central nervous system damage, neurosensory deafness and delayed psychomotor development may manifest as a result of asimptomatic congenital infection later in childhood. In the article we present basic properties of CMV; we describe clinical picture of the congenital infection and possibilities of diagnose and its treatment. We present five children with symptomatic congenital CMV infection that were hospitalized for the period 1992–2002 at the Neonatal department in the University Children’s Hospital in Ljubljana.Conclusions: Identification of infected neonates, especially those with asimptomatic congenital CMV infection, is difficult. Latest incidence of infection in Slovenia is unknown. With new investigations the efficiency of antiviral therapy was discovered but exact indications for therapy are not yet known. CMV vaccine, once available, may ultimately be the best control strategy for this important public health problem. Proper educating women in childbearing age about the risks of CMV and how to avoid disease transmission during pregnancy (hand washing, avoiding mouth-to-mouth contact with preschool children, usage of gloves especially when handling dipers or respiratory secretions are the only control strategies available.

    2017-05-01

    Congenital amusia (commonly known as tone deafness) is a lifelong musical disorder that affects 4% of the population according to a single estimate based on a single test from 1980. Here we present the first large-based measure of prevalence with a sample of 20 000 participants, which does not rely on self-referral. On the basis of three objective tests and a questionnaire, we show that (a) the prevalence of congenital amusia is only 1.5%, with slightly more females than males, unlike other developmental disorders where males often predominate; (b) self-disclosure is a reliable index of congenital amusia, which suggests that congenital amusia is hereditary, with 46% first-degree relatives similarly affected; (c) the deficit is not attenuated by musical training and (d) it emerges in relative isolation from other cognitive disorder, except for spatial orientation problems. Hence, we suggest that congenital amusia is likely to result from genetic variations that affect musical abilities specifically.

    Spondyloepiphyseal dysplasia congenita is a form of primarily short trunk dwarfism, that is manifest at birth but generally has not been regarded as a cause of lethal neonatal dwarfism. Seven neonates with severe dwarfism are presented. The first survived the newborn period, but the other six were early neonatal deaths. All displayed the clinical and radiologic features of spondyloepiphyseal dysplasia congenita. The striking similarities between spondyloepiphyseal dysplasia congenita and achondrogenesis type 2 are discussed.

    Experiments were conducted to examine the effects of changes in lighting schedules and food consumption on circadian rhythms in acetaminophen lethality and hepatic glutathione levels in male mice. Under a normal lighting schedule (light: 06.00-18.00 h), male mice exhibited a circadian rhythm in acetaminophen lethality (peak: 18.00 h; nadir: 06.00, 10.00 h) and an inverse rhythm in hepatic glutathione concentrations (peak: 06.00, 10.00 h; nadir: 18.00 h). Under a reversed lighting schedule (light: 18.00-06.00 h) the glutathione rhythm was reversed and the rhythm in acetaminophen lethality was altered showing greater sensitivity to the drug. Under continuous light, there was a shift in the acetaminophen lethality and the hepatic glutathione rhythms. Under continuous dark, both rhythms were abolished. Under a normal lighting regimen, hepatic glutathione levels were closely correlated with food consumption; i.e., both were increased during the dark phase and decreased during the light phase. Fasting the mice for 12 h abolished the rhythms in acetaminophen lethality and hepatic glutathione levels; moreover, the lethality was increased and the hepatic glutathione levels were decreased. These experiments show that both lighting schedules and feeding can alter the circadian rhythms in acetaminophen lethality and hepatic glutathione levels in male mice.

    Science.gov (United States)

    2014-01-01

    Background Control programs have been executed in an attempt to reduce vertical transmission and the severity of congenital infection in regions with a high incidence of toxoplasmosis in pregnant women. We aimed to evaluate whether treatment of pregnant women with spiramycin associated with a lack of monitoring for toxoplasmosis seroconversion affects the prognosis of patients. Methods We performed a prospective cohort study with 246 newborns (NB) at risk for congenital toxoplasmosis in Goiânia (Brazil) between October 2003 and October 2011. We analyzed the efficacy of maternal treatment with spiramycin. Results A total of 40.7% (66/162) of the neonates were born seriously infected. Vertical transmission associated with reactivation during pregnancy occurred in 5.5% (9/162) of the NB, with one showing severe infection (systemic). The presence of specific immunoglobulins (fetal IgM and NB IgA) suggested the worst prognosis. Treatment of pregnant women by spiramycin resulted in reduced vertical transmission. When infected pregnant women did not undergo proper treatment, the risk of severe infection (neural-optical) in NB was significantly increased. Fetal IgM was associated with ocular impairment in 48.0% (12/25) of the fetuses and neonatal IgA-specific was related to the neuro-ophthalmologic and systemic forms of the disease. When acute toxoplasmosis was identified in the postpartum period, a lack of monitoring of seronegative pregnant women resulted in a higher risk of severe congenital infection. Conclusion Treatment of pregnant women with spiramycin reduces the possibility of transmission of infection to the fetus. However, a lack of proper treatment is associated with the onset of the neural-optical form of congenital infection. Primary preventive measures should be increased for all pregnant women during the prenatal period and secondary prophylaxis through surveillance of seroconversion in seronegative pregnant woman should be introduced to reduce the

    Congenital factor VII (FVII) deficiency is the commonest type of the rare bleeding disorders. Very few cases of congenital FVII deficiency developed inhibitor and liver transplant is considered as definitive treatment. In the literature, twelve patients with congenital FVII deficiency developed inhibitors. Two had spontaneous resolution of inhibitors and one did not respond to high dose recombinant factor VIIa (rFVIIa) and died. Regarding liver transplant in congenital FVII patients, seven patients underwent liver transplant with good prognosis. We report a 5-year-old girl with confirmed severe congenital FVII deficiency since neonatal period. She suffered from recurrent intracranial bleeding despite rFVIIa replacement. After auxiliary liver transplant at the age of 4, she continued to show persistent deranged clotting profile and was found to have inhibitor towards FVII. Interestingly, she was still responsive to rFVIIa replacement. © 2016 John Wiley & Sons Ltd.

  19. Evaluation of congenital heart disease by magnetic resonance imaging

    2000-01-01

    Magnetic resonance imaging has proven to be useful in the assessment of patients with complex congenital heart disease and in the post-surgical follow-up of patients with corrected congenital heart disease. A thorough understanding of the congenital cardiac malformations that can be encountered is needed and the use of the sequential segmental analysis helps to standardize the evaluation and diagnosis of (complex) congenital heart disease. After surgical correction of congenital heart defects, patients must be followed over extended periods of time, because morphological and functional abnormalities may still be present or may develop. The use of echocardiography may be hampered in these patients as scar tissue and thorax deformities limit the acoustic window. Magnetic resonance imaging has proven to be advantageous in the follow-up of these post-surgical patients and with the use of several different techniques the morphological as well as functional abnormalities can be evaluated and followed over time.

    2013-01-01

    Full Text Available Syphilis is an infectious disease caused by Treponema pallidum and has high rates of vertical transmission, which can reach 100% depending on the maternal disease and stage of pregnancy. The diagnosis of gestational syphilis is simple and its screening is required during the prenatal period. However, this disease still has a high prevalence, affecting two million pregnant women worldwide. The procedures performed in newborns with congenital syphilis represent costs that are three-fold higher than the ones spent with a baby without this infection. The treatment is generally carried out with penicillin and must be extended to sexual partners. Inadequate or lack of treatment of congenital syphilis can result in miscarriage, premature birth, acute complications and other fetal sequelae. KEYWORDS: Congenital syphilis. Treponema pallidum.

    Full Text Available Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (1 year is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.

    Full Text Available Background: Congenital epidermolysis bullosa (CEB is a rare genodermatosis. The digestive system is very frequently associated with skin manifestations. Pyloric atresia (PA and oesophageal stenosis (OS are considered the most serious digestive lesions to occur.The aim of this work is to study the management and the outcome of digestive lesions associated to CEB in four children and to compare our results to the literature. Patients and Methods: A retrospective study of four observations: Two cases of PA and two cases of OS associated to CEB managed in the Paediatric Surgery Department of Fattouma Bourguiba Teaching Hospital in Monastir, Tunisia. Results: Four patients, two of them are 11 and 8 years old, diagnosed as having a dystrophic epidermolysis bullosa since the neonatal period. They were admitted for the investigation of progressive dysphagia. Oesophageal stenosis was confirmed by an upper contrast study. Pneumatic dilation was the advocated therapeutic method for both patients with afavourable outcome. The two other patients are newborns, diagnosed to have a CEB because of association of PA with bullous skin lesions with erosive scars. Both patients had a complete diaphragm excision with pyloroplasty. They died at the age of 4 and 3 months of severe diarrhoea resistant to medical treatment. Conclusion: Digestive lesions associated to CEB represent an aggravating factor of a serious disease. OS complicating CEB is severe with difficult management. Pneumatic dilatation is the gold standard treatment method. However, the mortality rate in PA with CEB is high. Prenatal diagnosis of PA is possible, and it can help avoiding lethal forms.

    Full Text Available Double lip, also referred to as "macrocheilia," is a rare anomaly which affects the upper lip more commonly than the lower lip. It consists of a fold of excess or redundant hypertrophic tissue on the mucosal side of the lip. The congenital double lip is believed to be present at birth and becomes more prominent after eruption of teeth. It affects esthetics and also interferes with speech and mastication. Simple surgical excision produces good functional and cosmetic results. We report a case of a non-syndromic congenital maxillary double lip in a 21-year-old male patient.

    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.) [de

    The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described.

    Full Text Available Congenital long QT syndrome type 3 (LQT3 is the third in frequency compared to the 15 forms known currently of congenital long QT syndrome (LQTS. Cardiac events are less frequent in LQT3 when compared with LQT1 and LQT2, but more likely to be lethal; the likelihood of dying during a cardiac event is 20% in families with an LQT3 mutation and 4% with either an LQT1 or an LQT2 mutation. LQT3 is consequence of mutation of gene SCN5A which codes for the Nav1.5 Na+ channel α-subunit and electrocardiographically characterized by a tendency to bradycardia related to age, prolonged QT/QTc interval (mean QTc value 478 ± 52 ms, accentuated QT dispersion consequence of prolonged ST segment, late onset of T wave and frequent prominent U wave because of longer repolarization of the M cell across left ventricular wall.

    Congenital heart defects represent the most common malformation at birth, occurring also in ∼50% of individuals with Down syndrome. Congenital heart defects are thought to have multifactorial etiology, but the main causes are largely unknown. We have explored the global methylation profile of fetal heart DNA in comparison to blood DNA from control subjects: an absolute correlation with the type of tissue was detected. Pathway analysis revealed a significant enrichment of differential methylation at genes related to muscle contraction and cardiomyopathies in the developing heart DNA. We have also searched for abnormal methylation profiles on developing heart-tissue DNA of syndromic and non-syndromic congenital heart defects. On average, 3 regions with aberrant methylation were detected per sample and 18 regions were found differentially methylated between groups. Several epimutations were detected in candidate genes involved in growth regulation, apoptosis and folate pathway. A likely pathogenic hypermethylation of several intragenic sites at the MSX1 gene, involved in outflow tract morphogenesis, was found in a fetus with isolated heart malformation. In addition, hypermethylation of the GATA4 gene was present in fetuses with Down syndrome with or without congenital heart defects, as well as in fetuses with isolated heart malformations. Expression deregulation of the abnormally methylated genes was detected. Our data indicate that epigenetic alterations of relevant genes are present in developing heart DNA in fetuses with both isolated and syndromic heart malformations. These epimutations likely contribute to the pathogenesis of the malformation by cis-acting effects on gene expression.

    Full Text Available Purpose. To study the effect of surgery on amblyopia and suppression associated with congenital cyclovertical strabismus. Methods. The fixation pattern was investigated with microperimetry before and soon after surgery in ten consecutive children operated for congenital superior oblique palsy at the S. Martino Hospital, Belluno, Italy, between September 2014 and December 2015. Changes in visual performance in terms of best-corrected visual acuity (BCVA and stereopsis between the day before and one week after surgery were also evaluated. No other amblyopia treatment has been administered during the time study. Results. Surgical correction of the excyclodeviation in congenital SO palsy determined monocular and binocular sensory consequences: monocularly, in the cyclodeviated amblyopic eye, BCVA (0.46–0.03 LogMAR; p<0.0001 and the fixation pattern improved, as demonstrated by microperimetry examination. Binocularly, stereopsis improved or emerged while suppression at the Worth four-dot test disappeared. Conclusions. In the absence of further amblyopic factors such as coexisting constant vertical and/or horizontal deviation and anisometropia, the amblyopia encountered in congenital SO palsy may resolve soon after the surgical alignment. Therefore, it may be considered and defined “pseudoamblyopia.”

    Objective To validate the estimates of Global Burden of Disease (GBD) due to congenital anomaly for Europe by comparing infant mortality data collected by EUROCAT registries with the WHO Mortality Database, and by assessing the significance of stillbirths and terminations of pregnancy for fetal anomaly (TOPFA) in the interpretation of infant mortality statistics. Design, setting and outcome measures EUROCAT is a network of congenital anomaly registries collecting data on live births, fetal deaths from 20 weeks’ gestation and TOPFA. Data from 29 registries in 19 countries were analysed for 2005–2009, and infant mortality (deaths of live births at age congenital anomaly. In 11 EUROCAT countries, average infant mortality with congenital anomaly was 1.1 per 1000 births, with higher rates where TOPFA is illegal (Malta 3.0, Ireland 2.1). The rate of stillbirths with congenital anomaly was 0.6 per 1000. The average TOPFA prevalence was 4.6 per 1000, nearly three times more prevalent than stillbirths and infant deaths combined. TOPFA also impacted on the prevalence of postneonatal survivors with non-lethal congenital anomaly. Conclusions By excluding TOPFA and stillbirths from GBD years of life lost (YLL) estimates, GBD underestimates the burden of disease due to congenital anomaly, and thus declining YLL over time may obscure lack of progress in primary, secondary and tertiary prevention.

    Congenital heart disease is a major cause of infant mortality in developed countries. In Spain, there are no publications at national level on mortality due to congenital heart disease. The aim of this study is to analyse mortality in infants with congenital heart disease, lethality of different types of congenital heart disease, and their variation over a ten-year period. A retrospective observational study was performed to evaluate mortality rate of children under one year old with congenital heart disease, using the minimum basic data set, from 2003 to 2012. Mortality rate and relative risk of mortality were estimated by Poisson regression. There were 2,970 (4.58%) infant deaths in a population of 64,831 patients with congenital heart disease, with 73.8% of deaths occurring during first week of life. Infant mortality rate in patients with congenital heart disease was 6.23 per 10,000 live births, and remained constant during the ten-year period of the study, representing 18% of total infant mortality rate in Spain. The congenital heart diseases with highest mortality rates were hypoplastic left heart syndrome (41.4%), interruption of aortic arch (20%), and total anomalous pulmonary drainage (16.8%). Atrial septal defect (1%) and pulmonary stenosis (1.1%) showed the lowest mortality rate. Congenital heart disease was a major cause of infant mortality with no variations during the study period. The proportion of infants who died in our study was similar to other similar countries. In spite of current medical advances, some forms of congenital heart disease show very high mortality rates.

    Congenital heart diseases (CHD) are being increasingly encountered in cardiac imaging due to improved outcomes from surgical and interventional techniques. Imaging plays an important role in the evaluation of CHD, both prior to and after surgeries and interventions. Computed tomography (CT) has several advantages in the evaluation of these disorders, particularly its high spatial resolution, multi-planar reconstruction capabilities at sub-millimeter isotropic resolution, good temporal resolution, wide field of view, and rapid turnaround time, which minimizes the need for sedation and anesthesia in young children or children with disabilities. With modern scanners, images can be acquired as fast as within one heartbeat. Although there is a risk of ionizing radiation, the radiation dose can be minimized by using several dose reduction strategies. There is a risk of contrast nephrotoxicity in patients with renal dysfunction. In this article, we will review the role of CT in the evaluation of several congenital heart diseases, both in children and adults.

    2013-05-01

    Congenital kyphoscoliosis (CKS) results from abnormal vertebral chondrification. Congenital fibrous bands occur in several locations with variable impact on vertebral development. We report a previously unreported case of a female infant with CKS presenting with an L2 hypoplastic vertebra and a costo-vertebral fibrous band extending to the skin in the form of a dimple. We also describe the therapeutic approach, consisting of surgical excision of the fibrous band and postoperative fulltime bracing, with a 7-year follow-up. We recommend a high index of suspicion in any unusual presentation of CKS and insist on case by case management in such cases.

    Congenital limb anomalies are manifested in various degree of severity and complexity bearing conclusion for description and nomenclature of each anomaly. We retrospectively analyzed the roentgenograms of congenital limb anomalies for the purpose of further understanding of the radiologic manifestations based on the embryonal defect and also to find the incidence of each anomaly. Total number of the patients was 89 with 137 anomalies. Recently the uniform system of classification for congenital anomalies of the upper limb was adopted by International Federation of Societies for Surgery of the Hand (IFSSH), which were categorized as 7 classifications. We used the IFSSH classification with some modification as 5 classifications; failure of formation of parts, failure of differentiation of parts, duplications, overgrowth and undergrowth. The patients with upper limb anomalies were 65 out of 89(73%), lower limb were 21(24%), and both upper and lower limb anomalies were 3(4%). Failure of formation was seen in 18%, failure of differentiation 39%, duplications 39%, overgrowth 8%, and undergrowth in 12%. Thirty-five patients had more than one anomaly, and 14 patients had intergroup anomalies. The upper limb anomalies were more common than lower limb. Among the anomalies, failure of differentiation and duplications were the most common types of congenital limb anomalies. Patients with failure of formation, failure of differentiation, and undergrowth had intergroup association of anomalies, but duplication and overgrowth tended to be isolated anomalies

    Full Text Available This article evaluates the use of lethal force by Mexican federal security forces during shootings with presumed members of organized crime from 2008-2014. The authors use official data and press reports on deaths and wounded in shootings to construct indicators such as the number of dead civilians over the number of dead officials from the federal security forces and the number of dead civilians over the number of wounded civilians. In a context where certain factors that contribute to an excessive use of force become more common, the results of the study show a growing use of lethal force. This raises questions over the possible excessive use of lethal force as a normal or systematic practice. The study also shows a growing context of opacity in the information available to evaluate the use of lethal force and the general lack of a legal framework to regulate the use of lethal force in Mexico.

    Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare, autosomal recessive disorder induced by mutations of the gene coding for thrombopoietin (TPO) receptor (c-MPL) despite high levels of serum TPO. Patients initially present with isolated thrombocytopenia that subsequently progresses into pancytopenia. Although the mechanisms leading to aplasia are unknown, the age of onset has been reported to depend on the severity of the c-MPL functional defect. The primary treatment for CAMT is bone marrow transplantation. This report describes a newborn girl who presented to us with symptoms of sepsis but septic profile came negative except thrombocytopenia. Bone marrow biopsy was done for thrombocytopenia which revealed amegakaryocytic thrombocytopenia. She was given prednisolone. (author)

    Congenital diaphragmatic hernia, despite advances in therapy, remains a complex condition with significant morbidity and mortality. The etiology of the disorder is still incompletely understood, though the pulmonary hypoplasia and pulmonary hypertension that develop secondarily must be overcome to improve survival. Prenatal US and fetal MRI have helped in the development of a greater understanding of this disease. Also with these modalities, measurement techniques have been developed in an attempt to provide prognosticators for the development of pulmonary hypoplasia and pulmonary hypertension. There is a broad range of approaches for performing these measurements, and variability among imaging centers is noted. Despite inconsistent approaches, these techniques have become the foundation for counseling and prenatal and postnatal therapy. It is hoped that with further research with prenatal US and fetal MRI and the development of innovative medical and surgical therapies that the morbidity and mortality of children with congenital diaphragmatic hernias can be significantly reduced.

  17. Congenital Hepatic Cyst

    Directory of Open Access Journals (Sweden)

    Aldo Recinos

    2017-04-01

    Full Text Available Congenital hepatic cyst is a rare and nonsymptomatic condition in infants and children. Its incidence is 2.5% in the postnatal life with a much lower incidence in the prenatal period. Incidental finding on antenatal imaging is the most common presentation. We present a case of a newborn in whom fetal ultrasound detected a cyst within the fetal liver. Postnatal imaging revealed a liver cyst in the right lobe of the liver, with no other intrahepatic structure affected. Liver function tests were abnormal, but the patient was asymptomatic. Posterior follow-up imaging showed a minor decrease in size. Management of congenital hepatic cyst is usually conservative, done with periodic ultrasound monitoring. However, surgical treatment is the mainstay of treatment when hydrops, progressive enlargement, hemorrhage, torsion, or compression of adjacent structures occurs. Malignant transformation can occur, but it is extremely rare. Partial or total removal of the cyst is the preferred treatment in neonates with a large lesion.

    With the advances in congenital cardiac surgery and postoperative care, an increasing number of children with complex congenital heart disease now reach adulthood. There are already more adults than children living with a congenital heart defect, including patients with complex congenital heart defects. Among these adults with congenital heart disease, a significant number will develop ventricular dysfunction over time. Heart failure accounts for 26-42% of deaths in adults with congenital heart defects. Heart transplantation, or heart-lung transplantation in Eisenmenger syndrome, then becomes the ultimate therapeutic possibility for these patients. This population is deemed to be at high risk of mortality after heart transplantation, although their long-term survival is similar to that of patients transplanted for other reasons. Indeed, heart transplantation in adults with congenital heart disease is often challenging, because of several potential problems: complex cardiac and vascular anatomy, multiple previous palliative and corrective surgeries, and effects on other organs (kidney, liver, lungs) of long-standing cardiac dysfunction or cyanosis, with frequent elevation of pulmonary vascular resistance. In this review, we focus on the specific problems relating to heart and heart-lung transplantation in this population, revisit the indications/contraindications, and update the long-term outcomes.

    Congenital diarrheal disorders (CDDs) are a group of inherited enteropathies with a typical onset early in the life. Infants with these disorders have frequently chronic diarrhea of sufficient severity to require parenteral nutrition. For most CDDs the disease-gene is known and molecular analysis may contribute to an unequivocal diagnosis. We review CDDs on the basis of the genetic defect, focusing on the significant contribution of molecular analysis in the complex, multistep diagnostic work-up.

    Full Text Available Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect pregnant women resulting in perinatal morbidity and mortality. Congenital syphilis is a preventable disease, and its presence reflects a failure of prenatal care delivery system, as well as syphilis control programs. We are reporting a case of late congenital syphilis with only Hutchinson′s teeth.

    Bouma, Berto J; Mulder, Barbara J M

    2017-03-17

    Congenital heart disease is the most frequently occurring congenital disorder affecting ≈0.8% of live births. Thanks to great efforts and technical improvements, including the development of cardiopulmonary bypass in the 1950s, large-scale repair in these patients became possible, with subsequent dramatic reduction in morbidity and mortality. The ongoing search for progress and the growing understanding of the cardiovascular system and its pathophysiology refined all aspects of care for these patients. As a consequence, survival further increased over the past decades, and a new group of patients, those who survived congenital heart disease into adulthood, emerged. However, a large range of complications raised at the horizon as arrhythmias, endocarditis, pulmonary hypertension, and heart failure, and the need for additional treatment became clear. Technical solutions were sought in perfection and creation of new surgical techniques by developing catheter-based interventions, with elimination of open heart surgery and new electronic devices enabling, for example, multisite pacing and implantation of internal cardiac defibrillators to prevent sudden death. Over time, many pharmaceutical studies were conducted, changing clinical treatment slowly toward evidence-based care, although results were often limited by low numbers and clinical heterogeneity. More attention has been given to secondary issues like sports participation, pregnancy, work, and social-related difficulties. The relevance of these issues was already recognized in the 1970s when the need for specialized centers with multidisciplinary teams was proclaimed. Finally, research has become incorporated in care. Results of intervention studies and registries increased the knowledge on epidemiology of adults with congenital heart disease and their complications during life, and at the end, several guidelines became easily accessible, guiding physicians to deliver care appropriately.

    Full Text Available AIMS: To determine the incidence of congenital toxoplasmosis in Colombian newborns from 19 hospital or maternal child health services from seven different cities of five natural geographic regions (Caribbean, Central, Andean, Amazonia and Eastern. MATERIALS AND METHODS: We collected 15,333 samples from umbilical cord blood between the period of March 2009 to May 2010 in 19 different hospitals and maternal-child health services from seven different cities. We applied an IgM ELISA assay (Vircell, Spain to determine the frequency of IgM anti Toxoplasma. The results in blood cord samples were confirmed either by western blot and repeated ELISA IgM assay. In a sub-sample of 1,613 children that were negative by the anti-Toxoplasma IgM assay, the frequency of specific anti-Toxoplasma IgA by the ISAGA assay was determined. All children with positive samples by IgM, IgA, clinical diagnosis or treatment during pregnancy were recalled for confirmatory tests after day 10 of life. RESULTS: 61 positive samples for specific IgM (0.39% and 9 positives for IgA (0.5% were found. 143 questionnaires were positive for a clinical diagnosis or treatment for toxoplasmosis during pregnancy. 109 out of the 218 children that had some of the criteria for postnatal confirmatory tests were followed. Congenital toxoplasmosis infection was confirmed in 15 children: 7 were symptomatic, and three of them died before the first month of life (20% of lethality. A significant correlation was found between a high incidence of markers for congenital toxoplasmosis and higher mean annual rainfall for the city. CONCLUSIONS: Incidence for congenital toxoplasmosis is significantly different between hospitals or maternal child health services from different cities in Colombia. Mean annual rainfall was correlated with incidence of congenital toxoplasmosis.

  11. Exome sequencing for gene discovery in lethal fetal disorders--harnessing the value of extreme phenotypes.

    Filges, Isabel; Friedman, Jan M

    2015-10-01

    Massively parallel sequencing has revolutionized our understanding of Mendelian disorders, and many novel genes have been discovered to cause disease phenotypes when mutant. At the same time, next-generation sequencing approaches have enabled non-invasive prenatal testing of free fetal DNA in maternal blood. However, little attention has been paid to using whole exome and genome sequencing strategies for gene identification in fetal disorders that are lethal in utero, because they can appear to be sporadic and Mendelian inheritance may be missed. We present challenges and advantages of applying next-generation sequencing approaches to gene discovery in fetal malformation phenotypes and review recent successful discovery approaches. We discuss the implication and significance of recessive inheritance and cross-species phenotyping in fetal lethal conditions. Whole exome sequencing can be used in individual families with undiagnosed lethal congenital anomaly syndromes to discover causal mutations, provided that prior to data analysis, the fetal phenotype can be correlated to a particular developmental pathway in embryogenesis. Cross-species phenotyping allows providing further evidence for causality of discovered variants in genes involved in those extremely rare phenotypes and will increase our knowledge about normal and abnormal human developmental processes. Ultimately, families will benefit from the option of early prenatal diagnosis. © 2014 John Wiley & Sons, Ltd.

    1996-01-01

    Pseudomonas aeruginosa has shown an increased sensitivity compared with that of Escherichia coli and Enterobacter cloacae, when they were exposed to 0.4 kJ/m2 of ultraviolet-B radiation. The rapid decay in cell viability observed in Pseudomonas aeruginosa after the irradiation was influenced by factors such as culture media and the presence of pyocyanine during the irradiation. The radioinduced lethal damage could be prevented by photoreactivating treatment, indicating that pyrimidine dimer formation was the mechanism causing bacterial death. The results indicate that several environmental conditions may act as protective agents against ultraviolet-B-induced damage

    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.

    Full Text Available Congenital midureteric obstruction is a rare entity which can be caused by either ureteric valves or strictures. We report our experience with four patients with midureteric obstruction due to stricture over a six-year period. The condition needs to be differentiated from obstruction of the pelviureteric and vesicoureteric junctions. Obstruction can be initially screened by ultrasound and confirmed by a radionuclide scan with furosemide challenge. Retrograde ureteropyelography and/or intravenous urography may be required to define the level of the stricture.

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and “on-time” puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

    As of late, the incidence of congenital syphilis in the United States is increasing. Each new case represents a failure of preventing, diagnosing, and treating syphilis in pregnant women. Pediatricians should confirm that all women have received adequate screening for and management of syphilis during pregnancy. Congenital syphilis is easily treatable but may be a diagnostic challenge with high morbidity and mortality.

    2001-07-01

    Full Text Available Background. Myotonic dystrophy is inherited as an autosomal dominant trait. It is characterized by myotonia, myopathy of voluntary and involuntary muscles, frontal baldness in men, cardiac conduction abnormalities, catharacts, intellectual deterioration and endocrinopathy. Men with this disorder have often gonadal atrophy and infertility. On the other hand women are generally fertile. During pregnancy their myopathy worsens, often causing severe obstetrical complications. Their children may develop congenital form of the disease with signs of myopathy in utero and have great difficulties in maintaining life functions after birth, together with other characteristical signs of this form: bilateral facial weakness, severe hypotonia, feeding difficulties, talipes equinovarus and mental retardation. The authors present a female newborn with such congenital form of myotonic dystrophy.Conclusions. The authors have emphasized the importance of medical history, regular updating of all the cases of neuromuscular diseases in the region and clinical characteristics for the recognition of congenital form of myotonic dystrophy because of possible prenatal diagnostics and better antenatal and postantal care.

    We report a case of bilateral temporal bone anomalies in a child with symptomatic congenital cytomegalovirus infection and severe, bilateral sensorineural hearing loss identified at 3 months of age. High-resolution temporal bone computed tomography (HRCT) revealed bilateral findings of a short, malformed cochlea lacking an interscalar septum, a short and wide internal auditory canal, and an enlarged vestibular aqueduct, features diagnostic of bilateral Mondini dysplasia. To determine the importance of this observation, we completed HRCT in five additional children between 7 months and 9 years of age who had evidence of symptomatic congenital cytomegalovirus infection. One child with profound sensorineural hearing loss had severe bilateral temporal bone dysplasia with a small cochlea lacking an interscalar septum, an abnormal vestibule, and a large cochlear aqueduct. Of the remaining four children, hearing thresholds ranged from normal to profoundly decreased, but their HRCT scans were normal to visual inspection. When inner ear dimensions of these temporal bones were compared with norms established by Pappas and coworkers, however, seven of the eight ears had short cochleas and narrow lateral semicircular canals, and three ears had short or narrow vestibules. These results indicate that congenital cytomegalovirus infection may cause anomalies or growth disturbances of the temporal bone.

    The association between pediatric cancer and congenital abnormalities is well known but, there is no exclusive data on the neonatal period and the underlying etiopathogenic mechanisms are unknown. First, to analyze the frequency of neonatal tumours associated with congenital abnormalities; and second, to comment on the likely etiopathogenic hypotheses of a relationship between neonatal tumours and congenital abnormalities. Historical series of neonatal tumours from La Fe University Children's Hospital in Valencia (Spain), from January 1990 to December 1999. Histological varieties of neonatal tumours and associated congenital abnormalities were described. A systematic review of the last 25 years was carried out using Medline, Cancerlit, Index Citation Science and Embase. The search profile used was the combination of "neonatal/congenital-tumors/cancer/neoplasms" and "congenital malformations/birth defects". 72 neonatal tumours were identified (2.8% of all pediatric cancers diagnosed in our hospital) and in 15 cases (20.8%) there was some associated malformation, disease or syndrome. The association between congenital abnormalities and neonatal tumours were: a) angiomas in three patients: two patients with congenital heart disease with a choanal stenosis, laryngomalacia; b) neuroblastomas in two patients: horseshoe kidney with vertebral anomalies and other with congenital heart disease; c) teratomas in two patients: one with cleft palate with vertebral anomalies and other with metatarsal varus; d) one tumour of the central nervous system with Bochdaleck hernia; e) heart tumours in four patients with tuberous sclerosis; f) acute leukaemia in one patient with Down syndrome and congenital heart disease; g) kidney tumour in one case with triventricular hydrocephaly, and h) adrenocortical tumour: hemihypertrophy. The publications included the tumours diagnosed in different pediatric periods and without unified criteria to classify the congenital abnormalities. Little data

  8. Congenital Becker's nevus with a familial association.

    Book, S E; Glass, A T; Laude, T A

    1997-01-01

    Becker's nevus is a unilateral, hyperpigmented cutaneous hamartoma usually with hypertrichosis. It occurs predominantly in boys, becoming apparent during adolescence, although several cases of congenital Becker's nevus have been reported. Rarely it may be familial and as such is transmitted in an autosomal dominant pattern. We report a 16-month-old black boy with a hyperpigmented patch on his right shoulder and upper pectoral area that extended down his arm. The patient's father has a similar lesion with hair on his left shoulder which has been present since childhood. Histology of the child's lesion was consistent with Becker's nevus. We believe this to be the first reported case of a congenital Becker's nevus with a familial association.

The precise diagnosis requires detailed clinical examination and electrophysiological findings. This case report presents two male patients with congenital nystagmus examined longitudinally from the age of six months until 17-18 years of age. Clinical and electrophysiological protocols were detailed. The first results showed electronegative electroretinography in the two cases and examination combined with electroretinographic findings helped us to make the diagnosis of Congenital Night Stationary Blindness (CSNB. This diagnosis was confirmed by genetic studies. CSNB is interesting to study because through electrophysiological findings, it enables a better understanding of the physiology of neural transmission in the outer part of the retina.Keywords: Congenital nystagmus, negative electroretinography, congenital night stationary blindness

    Congenital Leukemia is a condition and often associated with fatal outcome/sup 1/. Most of the neonatal cases reported have acute non-lymphoblastic leukemia, in contrast to the predominance of acute lymphoblastic leukemia found in later childhood. congenital leukemia is occasionally associated with number of congenital anomalies and with chromosomal disorders such as Down's syndrome. Subtle cytogenetic abnormalities may occur more commonly in the affected infants and their parents, when studied with newer cytogenetic techniques/sup 2/. Inherent unstable hematopoieses resulting from chromosomal aberration in children with Downs's syndrome can present with transient myeloproliferative disorder, mimicking leukemia which undergoes spontaneous recovery/sup 3/.

    Congenital torticollis is an intriguing condition of unknown origin, characterized by unilateral shortening and tightness of the sternocleidomastoid muscle. Patients usually present with head tilt, facial asymmetry and plagiocephaly. A sternomastoid mass or tumor may or may not be clinically apparent. Untreated, cervical function and facial cosmesis may be severely compromised. Objective: My study is aimed at establishing a comparison between the incidence of right versus left sided congenital torticollis. Method: This observational study included 30 patients of congenital torticollis that completed the questionnaire. The data was collected from patients coming to the Physiotherapy and Orthopedic departments of Children Hospital, Lahore. Results: Results showed that right side was involved in 19 (63.3%) patients and left side was involved in 11 (36.7%) patients. Out of 30 patients, 14 (46.7%) were male, of which 8 had right sided congenital torticollis and 6 had left sided congenital torticollis, and 16 (53.3%) were female, of which right sided congenital torticollis and 5 had left sided congenital torticollis. Conclusion: Hence it is concluded that incidence of right sided congenital torticollis is more common than left sided congenital torticollis. The incidence of con-genital torticollis is higher in females than in males. (author)

    A congenital extrahepatic portosystemic shunt (CEPS) is uncommon. A type 1 CEPS exists where there is absence of intrahepatic portal venous supply and a type 2 CEPS where this supply is preserved. The diagnosis of congenital portosystemic shunt is important because it may cause hepatic encephalopathy. To describe the clinical and imaging features of three children with CEPS and to review the cases in the published literature. The diagnostic imaging and medical records for three children with CEPS were retrieved and evaluated. An extensive literature search was performed. Including our cases, there are 61 reported cases of CEPS, 39 type 1 and 22 type 2. Type 1 occurs predominantly in females, while type 2 shows no significant sexual preponderance. The age at diagnosis ranges from 31 weeks of intrauterine life to 76 years. Both types of CEPS have a number of associations, the most common being nodular lesions of the liver (n=25), cardiac anomalies (n=19), portosystemic encephalopathy (n=10), polysplenia (n=9), biliary atresia (n=7), skeletal anomalies (n=5), and renal tract anomalies (n=4). MRI is recommended as an important means of diagnosing and classifying cases of CEPS and examining the associated cardiovascular and hepatic abnormalities. Screening for CEPS in patients born with polysplenia is suggested. (orig.)

    Clinical congenital anophthalmia is described as the uni- or bilateral absence of the eyeball that might occur in isolation or as part of a syndrome. It has a very low prevalence and its etiology is heterogeneous. Complex congenital cardiac malformations are also rare. The association of congenital anophthalmia and congenital heart disease is rarer still, and the etiology of those associations is not well understood yet. We report the case of a patient who had the very rare association of bilateral anophthalmia, multiple cardiac malformations and severe pulmonary hypertension.

    Full Text Available OBJECTIVE: To review the relationship between congenital heart defects and chromosomal abnormalities detected by the karyotype.DATA SOURCES: Scientific articles were searched in MEDLINE database, using the descriptors "karyotype" OR "chromosomal" OR "chromosome" AND "heart defects, congenital". The research was limited to articles published in English from 1980 on.DATA SYNTHESIS: Congenital heart disease is characterized by an etiologically heterogeneous and not well understood group of lesions. Several researchers have evaluated the presence of chromosomal abnormalities detected by the karyotype in patients with congenital heart disease. However, most of the articles were retrospective studies developed in Europe and only some of the studied patients had a karyotype exam. In this review, only one study was conducted in Latin America, in Brazil. It is known that chromosomal abnormalities are frequent, being present in about one in every ten patients with congenital heart disease. Among the karyotype alterations in these patients, the most important is the trisomy 21 (Down syndrome. These patients often have associated extra-cardiac malformations, with a higher risk of morbidity and mortality, which makes heart surgery even more risky.CONCLUSIONS: Despite all the progress made in recent decades in the field of cytogenetic, the karyotype remains an essential tool in order to evaluate patients with congenital heart disease. The detailed dysmorphological physical examination is of great importance to indicate the need of a karyotype.

    Objective Central systolic blood pressure (SBP) is a measure of arterial stiffness and strongly associated with atherosclerosis and end-organ damage. It is a stronger predictor of cardiovascular events and all-cause mortality than peripheral SBP. In particular, for children with congenital heart disease, a higher central SBP might impose a greater threat of cardiac damage. The aim of the study was to analyse and compare central SBP in children with congenital heart disease and in healthy counterparts. Patients and methods Central SBP was measured using an oscillometric method in 417 children (38.9% girls, 13.0 ± 3.2 years) with various congenital heart diseases between July 2014 and February 2017. The test results were compared with a recent healthy reference cohort of 1466 children (49.5% girls, 12.9 ± 2.5 years). Results After correction for several covariates in a general linear model, central SBP of children with congenital heart disease was significantly increased (congenital heart disease: 102.1 ± 10.2 vs. healthy reference cohort: 100.4 ± 8.6, p congenital heart disease subgroups revealed higher central SBP in children with left heart obstructions (mean difference: 3.6 mmHg, p congenital heart disease have significantly higher central SBP compared with healthy peers, predisposing them to premature heart failure. Screening and long-term observations of central SBP in children with congenital heart disease seems warranted in order to evaluate the need for treatment.

    2011-05-01

    Full Text Available Abstract The term congenital neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, severe ( When neutropenia is detected, an attempt should be made to establish the etiology, distinguishing between acquired forms (the most frequent, including post viral neutropenia and auto immune neutropenia and congenital forms that may either be isolated or part of a complex genetic disease. Except for ethnic neutropenia, which is a frequent but mild congenital form, probably with polygenic inheritance, all other forms of congenital neutropenia are extremely rare and have monogenic inheritance, which may be X-linked or autosomal, recessive or dominant. About half the forms of congenital neutropenia with no extra-hematopoetic manifestations and normal adaptive immunity are due to neutrophil elastase (ELANE mutations. Some patients have severe permanent neutropenia and frequent infections early in life, while others have mild intermittent neutropenia. Congenital neutropenia may also be associated with a wide range of organ dysfunctions, as for example in Shwachman-Diamond syndrome (associated with pancreatic insufficiency and glycogen storage disease type Ib (associated with a glycogen storage syndrome. So far, the molecular bases of 12 neutropenic disorders have been identified. Treatment of severe chronic neutropenia should focus on prevention of infections. It includes antimicrobial prophylaxis, generally with trimethoprim-sulfamethoxazole, and also granulocyte-colony-stimulating factor (G-CSF. G-CSF has considerably improved these patients' outlook. It is usually well tolerated, but potential adverse effects include thrombocytopenia, glomerulonephritis, vasculitis and osteoporosis. Long-term treatment with G-CSF, especially at high doses, augments the spontaneous risk of leukemia in patients with congenital neutropenia.

They include, achondrogenesis, thanatophoric dysplasia, asphyxiating thoracic dysplasia, osteogenesis imperfect a congenita, and hypophosphatasia lethals. Five babies were born alive but died soon after birth and one was a stillbirth. The main cause of failure to thrive was respiratory insufficiency. Each case was having quite characteristic radiologic findings, even if the general appearances were similar to the achondroplasts clinically. Precise diagnosis is very important for genetic counselling of the parents and alarm to them the possibility of bone dysplasias to the next offsprings. For this purpose, the radiologists play major role for the correct diagnosis. We stress that when the baby is born with short-limbed dwarfism, whole body radiogram should be taken including lateral view and postmortem radiogram is also very precious.

    Full Text Available Evidence of interpersonal violence has been documented previously in Pleistocene members of the genus Homo, but only very rarely has this been posited as the possible manner of death. Here we report the earliest evidence of lethal interpersonal violence in the hominin fossil record. Cranium 17 recovered from the Sima de los Huesos Middle Pleistocene site shows two clear perimortem depression fractures on the frontal bone, interpreted as being produced by two episodes of localized blunt force trauma. The type of injuries, their location, the strong similarity of the fractures in shape and size, and the different orientations and implied trajectories of the two fractures suggest they were produced with the same object in face-to-face interpersonal conflict. Given that either of the two traumatic events was likely lethal, the presence of multiple blows implies an intention to kill. This finding shows that the lethal interpersonal violence is an ancient human behavior and has important implications for the accumulation of bodies at the site, supporting an anthropic origin.

    Evidence of interpersonal violence has been documented previously in Pleistocene members of the genus Homo, but only very rarely has this been posited as the possible manner of death. Here we report the earliest evidence of lethal interpersonal violence in the hominin fossil record. Cranium 17 recovered from the Sima de los Huesos Middle Pleistocene site shows two clear perimortem depression fractures on the frontal bone, interpreted as being produced by two episodes of localized blunt force trauma. The type of injuries, their location, the strong similarity of the fractures in shape and size, and the different orientations and implied trajectories of the two fractures suggest they were produced with the same object in face-to-face interpersonal conflict. Given that either of the two traumatic events was likely lethal, the presence of multiple blows implies an intention to kill. This finding shows that the lethal interpersonal violence is an ancient human behavior and has important implications for the accumulation of bodies at the site, supporting an anthropic origin.

    Congenital heart disease in adults (adult congenital heart disease) is a growing burden for healthcare systems. While infant mortality due to congenital heart disease in the last four decades decreased by almost 3-fold, adult congenital heart disease prevalence increased by more than 2-fold in United States. Adult congenital heart disease prevalence is expected to increase steadily until 2050 in projections. Adult congenital heart disease is a multifaceted problem with many dimensions. This manuscript aims to provide an overview of the common adult congenital heart diseases and summarize important points in management of these diseases with possible problems and complications that the patients and the physicians face.

    Congenital hypothyroidism is a treatable disease if detected at the early stage of life. It is one of the most frequent cause of mental retardation in children. In 85 % of cases, congenital hypothyroidism is a consequence of thyroid disgenesis, in which the gland is either absent, located ectopically and/or severely reduced in size. Early detection and treatment with thyroid hormone supplement can significantly reduce mental damage. In 1996, Thailand initiated a neonatal screening programme for congenital hypothyroidism (CHT) and phenylketonuria (PKU), with the objective of bringing a better quality of life to people throughout the country, but especially in the remote areas. The programme involves implementing routine screening nationwide. The plan of action was designed with the goal of having public health service units throughout the country provide neonatal screening by year 2002 for the 1.2 million babies born per annum in Thailand. The government supported the programme by allocating a five-year budget of approximately US$15 million. The programme received additional assistance through technical support and human resource development from the International Atomic Energy Agency (IAEA) and the US Centers for Disease Control. This assistance promoted self-sustainability and strengthened the programme's technical base. The programme is on track. It is expected that by year 2002 all new born babies in Thailand will be screened for CHT and PKU

    Full Text Available The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability or failing of milk production. Moreover, they cause animal welfare reduction because they can imply foetal dystocia and because the affected animals have a reduced fitness with little chances of survival. This review depicts, in the river buffalo (Bubalus bubalis world population, the present status of the congenital malformations, due to genetic causes, to identify their frequency and distribution in order to develop genetic breeding plans able to improve the productive and reproductive performance, and avoid the spreading of detrimental gene variants. Congenital malformations most frequently reported in literature or signaled by breeders to the Department of Veterinary Medicine and Animal Production of the University Federico II (Naples, Italy in river buffalo are: musculoskeletal defects (transverse hemimelia, arthrogryposis, umbilical hernia and disorders of sexual development. In conclusion this review put in evidence that river buffalo have a great variety of malformations due to genetic causes, and TH and omphalocele are the most frequent and that several cases are still not reported, leading to an underestimation of the real weight of genetic diseases in this species.

  14. An integrated diagnosis strategy for congenital myopathies.

    Directory of Open Access Journals (Sweden)

    Johann Böhm

    Full Text Available Congenital myopathies are severe muscle disorders affecting adults as well as children in all populations. The diagnosis of congenital myopathies is constrained by strong clinical and genetic heterogeneity. Moreover, the majority of patients present with unspecific histological features, precluding purposive molecular diagnosis and demonstrating the need for an alternative and more efficient diagnostic approach. We used exome sequencing complemented by histological and ultrastructural analysis of muscle biopsies to identify the causative mutations in eight patients with clinically different skeletal muscle pathologies, ranging from a fatal neonatal myopathy to a mild and slowly progressive myopathy with adult onset. We identified RYR1 (ryanodine receptor mutations in six patients and NEB (nebulin mutations in two patients. We found novel missense and nonsense mutations, unraveled small insertions/deletions and confirmed their impact on splicing and mRNA/protein stability. Histological and ultrastructural findings of the muscle biopsies of the patients validated the exome sequencing results. We provide the evidence that an integrated strategy combining exome sequencing with clinical and histopathological investigations overcomes the limitations of the individual approaches to allow a fast and efficient diagnosis, accelerating the patient's access to a better healthcare and disease management. This is of particular interest for the diagnosis of congenital myopathies, which involve very large genes like RYR1 and NEB as well as genetic and phenotypic heterogeneity.

    Pediatric cardiology has made great strides in the diagnosis, management, and correction of complex congenital malformations in the past two decades. The foundation of these advances is a more precise understanding of the physiology and anatomy of complex lesions that has been obtained from cardiac catheterization and angiography. The techniques for catheterization of infants and children have been discussed in another paper. This chapter focuses on brief profiles of some of the more important congenital abnormalities. The incidence cited in the discussion of each abnormality pertains to a population comprises of children and adults referred to The Children's Hospital Medical Center and Peter Bent Brigham Hospital, respectively, for evaluation of congenital heart disease

    Nasal airway obstruction is a potentially life-threatening condition in the newborn. Neonates are obligatory nasal breathers. The pyriform aperture is the narrowest, most anterior bony portion of the nasal airway, and a decrease in its cross-sectional area will significantly increase nasal airway resistance. Congenital nasal pyriform aperture stenosis (CNPAS) is a rare, unusual form of nasal obstruction. It should be considered in the differential diagnosis of any neonate or infant with signs and symptoms of upper airway compromise. It is important to differentiate this level of obstruction from the more common posterior choanal stenosis or atresia. CNPAS presents with symptoms of nasal airway obstruction, which are often characterized by episodic apnea and cyclical cyanosis. (orig.)

    The ability to make sense of the music in our environment involves sophisticated cognitive mechanisms that, for most people, are acquired effortlessly and in early life. A special population of individuals, with a disorder termed congenital amusia, report lifelong difficulties in this regard. Exploring the nature of this developmental disorder provides a window onto the cognitive architecture of typical musical processing, as well as allowing a study of the relationship between processing of music and other domains, such as language. The present article considers findings concerning pitch discrimination, pitch memory, contour processing, experiential aspects of music listening in amusia, and emerging evidence concerning the neurobiology of the disorder. A simplified model of melodic processing is outlined, and possible loci of the cognitive deficit are discussed.

    The past decade of research has provided compelling evidence that musical engagement is a fundamental human trait, and its biological basis is increasingly scrutinized. In this endeavor, the detailed study of individuals who have musical deficiencies is instructive because of likely neurogenetic underpinnings. Such individuals have 'congenital amusia', an umbrella term for lifelong musical disabilities that cannot be attributed to intellectual disability, lack of exposure, or brain damage after birth. Key points are reviewed here that have emerged during recent years regarding the neurobiology of the disorder, focusing on the importance of recurrent processing between the right inferior frontal cortex and the auditory cortex for conscious monitoring of musical pitch, and how this relates to developmental cognitive disorders in general.

    Congenital adrenal hyperplasia (CAH) describes a family of disorders that comes from enzymatic deficiencies in cortisol production, with 21-hydroxylase deficiency causing ∼90% of cases. Distinction is made between the severe classical form and milder nonclassical form of CAH. Molecular genetic analysis is used to confirm the hormonal diagnosis. A high rate of genotype-phenotype disconcordance has been found in 21-hydroxylase deficiency. The goal of treatment is to replace with synthetic glucocorticoids and mineralocorticoids and suppress adrenal androgen production. The treatment of patients affected with nonclassical CAH, particularly males, remains controversial. Variable synthetic glucocorticoids are used and new modes of glucocorticoid delivery are under investigation. To improve height, growth hormone and other adjuvant therapies are employed. Long-term outcomes of genital surgery using modern techniques in females affected with classical CAH continue to be investigated. Prenatal treatment with dexamethasone is available to avoid ambiguous genitalia in these females. Although studies have shown its safety to mother and fetus, prenatal treatment is still regarded as experimental. Currently, prenatal diagnosis of CAH can only be obtained through invasive methods. Recently, the detection of cell-free fetal DNA in maternal plasma has made it possible to make this diagnosis earlier and noninvasively. © 2016 S. Karger AG, Basel.

    2015-05-01

    Full Text Available Among Herpesviruses, Human Cytomegalovirus (HCMV or HHV-5 represents a major threat during congenital or neonatal infections, which may lead to encephalitis with serious neurological consequences. However, as opposed to other less prevalent pathogens, the mechanisms and genetic susceptibility factors for CMV encephalitis are poorly understood. This lack of information considerably reduces the prognostic and/or therapeutic possibilities. To easily monitor the effects of genetic defects on brain dissemination following CMV infection we used a recently developed in vivo mouse model based on the neonatal inoculation of a MCMV genetically engineered to express Luciferase. Here, we further validate this protocol for live imaging, and demonstrate increased lethality associated with viral infection and encephalitis in mutant mice lacking Dicer activity. Our data indicate that miRNAs are important players in the control of MCMV pathogenesis and suggest that miRNA-based endothelial functions and integrity are crucial for CMV encephalitis.

    Congenital anomalies of the limbs have been observed since ancient human civilizations, capturing the imagination of ancient physicians and people. The knowledge of the era could not possibly theorize on the biologic aspects of these anomalies; however, from the very beginning of civilization the spiritual status of people attempted to find a logical explanation for the existence of such cases. The next logical step of the spiritual and religious system of the ancients was to correlate these anomalies with the Gods and to attribute them to a different level of existence in order to rationalize their existence. In these settings, the mythology and religious beliefs of ancient civilizations comprised several creatures that were related to the observed congenital anomalies in humans. The purpose of this historic review is to summarize the depiction of congenital anomalies of the limbs in mythology and antiquity, to present several mythological creatures with resemblance to humans with congenital anomalies of the limbs, to present the atmosphere of the era concerning the congenital anomalies, and to theorize on the anomaly and medical explanation upon which such creatures were depicted. Our aim is to put historic information in one place, creating a comprehensive review that the curious reader would find interesting and enjoyable.

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

    2006-01-01

    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)

    Full Text Available Cytomegalovirus (CMV is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID, which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS. Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at 72?#608;for 5 seconds can eliminate CMV completely.

    Congenital candidiasis is a severe complication of candidal vulvovaginitis. It occurs in two forms,congenital mucocutaneous candidiasis and congenital systemic candidiasis. Also newborns are in age group the most vulnerable to invasive candidiasis. Congenital candidiasis should be considered as an interdisciplinary problem including maternal and fetal condition (including antibiotic therapy during pregnancy), birth age and rare genetic predispositions as severe combined immunodeficiency or neutrophil-specific granule deficiency. Environmental factors are no less important to investigate in diagnosing, treatment and prevention. External factors (e.g., food) and microenvironment of human organism (microflora of the mouth, intestine and genitalia) are important for solving clinical problems connected to congenital candidiasis. Physician knowledge about microorganisms in a specific compartments of the microenvironment of human organism and in the course of defined disorders of homeostasis makes it easier to predict the course of the disease and allows the development of procedures that can be extremely helpful in individualized diagnostic and therapeutic process.

    Congenital central hypoventilation syndrome (CCHS) is a rare neurocristopathy with severe central hypoventilation. CCHS results from a mutation in the paired-like homeobox 2B gene (PHOX2B). In addition to hypoventilation, patients with CCHS display a wide array of autonomic nervous system abnormalities, including decreased heart rate variability and abrupt sinus pauses, esophageal dysmotility, abnormal pupillary light response, and temperature dysregulation, to name a few. To date, there has been no documentation of a child with both CCHS and hyperthyroidism. We report the case of a young child with CCHS who presented with tachycardia, which was later found to be due to Grave's disease, after many months of investigation.

    A blue roan Percheron foal was born with poorly circumscribed patchy alopecia of the trunk and legs. Teeth and hoof development were normal. Alopecia was progressive, becoming almost complete by 1 year of age. Histopathological findings in a skin biopsy obtained at 7 months of age were consistent with severe follicular hypoplasia. Sebaceous glands, epitrichial sweat glands and arrector pilae muscles were normal. The horse is alive and otherwise well at 6 years of age, although adult stature is considered small for this breed. The clinical history and histopathological findings are most consistent with a form of congenital hypotrichosis.

    Simple Summary Congenital malformations (due to genetic causes) represent a hidden danger for animal production, above all when genetic selection is undertaken for production improvements. These malformations are responsible for economic losses either because they reduce the productivity of the farm, or because their spread in the population would decrease the total productivity of that species/breed. River buffalo is a species of increasing interest all over the world for its production abilities, as proved by the buffalo genome project and the genetic selection plans that are currently performed in different countries. The aim of this review is to provide a general view of different models of congenital malformations in buffalo and their world distribution. This would be useful either for those who performed buffalo genetic selection or for researchers in genetic diseases, which would be an advantage to their studies with respect to the knowledge of gene mutations and interactions in this species. Abstract The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability or failing of milk production. Moreover, they cause animal welfare reduction because they can imply foetal dystocia and because the affected animals have a reduced fitness with little chances of survival. This review depicts, in the river buffalo (Bubalus bubalis) world population, the present status of the congenital malformations, due to genetic causes, to identify their frequency and distribution in order to develop genetic breeding plans able to improve the productive and reproductive performance, and avoid the spreading of detrimental gene variants.

    Full Text Available Background: Long QT syndromes (LQT are genetic abnormalities of ventricular repo-larization, with an estimated incidence of about one per 10000 births. It is characterized by prolongation of the QT interval in electrocardiogram (EKG and associated with a high risk for syncope and sudden death in patients. Type of this syndrome is association with congenital deafness. Our objective was to evaluate QT interval in children with congenital deafness.Methods: For 219 patients referred to Imam Khomeini Hospital audiometric clinic in 2011, questionnaire were completed. A total of 23 congenitally deaf children were incl-uded. All patients’ examinations were done by a pediatric cardiologist. Electrocardio-gram is conducted in all children (23 patients with sever and deep congenital deafness. Then the QT interval was measured based on Bazett’s formula. Echocardiography was also performed in these children to assess left ventricular function and the presence of mitral valve prolapse.Results: The overall patients were two hundred and nineteen children. A total of twenty three congenitally deaf children were included and electrocardiogram was obtained. Three children had obviously prolonged QTc (0.48±0.02 second. The median age of them was 6.1±5 year, the median weight was 18±11.3 kilogram and the median of QT interval was 0.48±0.02 second.Conclusion: The QT interval obtained 0.48±0.02 second. In the present study we found prolonged QT in congenital deafness, thus we recommend to evaluate the electrocardio-gram of children with congenital deafness.

    Congenital coronary artery fistula (CCAF) is communication of a coronary artery or its main branch with one of the atria or ventricles, the coronary sinus, the superior vena cava, or the pulmonary artery. In Korean peoples, only 4 cases of the CCAF were reported as rare as worldwide and authors want to report another case of CCAF, confirmed by operation. 10-year-old girl shows a fistula between sinus node artery of the right coronary artery and right atrium on root aortogram with left-to-right shunt and Qp/Qs=1.58, in which simple ligation of the sinus node artery from right coronary artery was performed. All of the 5 Korean CCAF (4 were previously reported and 1 of authors) were originated from right coronary artery, and of which 4 were opening into right ventricle and 1 of authors were into right atrium. Associated cardiac anomaly was noted in only 1 case as single coronary artery. Ages were from 9 months of age to 10 years old and no adult left case were found. 3 were female and 2 were male patients.

A literature review was conducted on Medline considering the articles listed until January 2012. Hypospadias is the most common malformation (1 in 250 boys. Familial forms: 7%). The causes remain hypothetical but the doubling of the incidence in 30 years could be linked to fetal exposure to endocrine disruptors "estrogen-like" used in the food industry in particular. Surgical treatment is usually intended to improve the aesthetic appearance but sometimes, in case of significant curvature or posterior meatus, necessary for normal sexual life and fertility. Other malformations (epispades, buried penis, transpositions, twists and preputial abnormalities) as well as management for functional or aesthetic consequences of these malformations in adulthood require complex surgical care in a specialized environment. The improvement of surgical techniques and pediatric anesthesia allows an early and effective specialized surgical approach of penile malformations. Management of sequelae in adulthood must be discussed and requires experience of surgical techniques on pediatric and adult penis. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    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.)

    Protein-losing enteropathy (PLE) is characterised by gastrointestinal protein leakage due to loss of mucosal integrity or lymphatic abnormalities. PLE can manifest as congenital diarrhoea and should be differentiated from other congenital diarrhoeal disorders. Primary PLEs are genetically heterogeneous and the underlying genetic defects are currently emerging. We report an infant with fatal PLE for whom we aimed to uncover the underlying pathogenic mutation. We performed whole exome sequencing (WES) for the index patient. Variants were classified based on the American College of Medical Genetics and Genomics guidelines. WES results and our detailed clinical description of the patient were compared with the literature. We discovered a novel homozygous stop mutation (c.988C>T, p.Q330*) in the Plasmalemma Vesicle-Associated Protein ( PLVAP ) gene in a newborn with fatal PLE, facial dysmorphism, and renal, ocular and cardiac anomalies. The Q330* mutation is predicted to result in complete loss of PLVAP protein expression leading to deletion of the diaphragms of endothelial fenestrae, resulting in plasma protein extravasation and PLE. Recently, another single homozygous stop mutation in PLVAP causing lethal PLE in an infant was reported. Our findings validate PLVAP mutations as a cause of syndromic PLE. Prenatal anomalies, severe PLE and syndromic features may guide the diagnosis of this rare disease. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Congenital hip dislocation is a perfect example of public health problems: its incidence is high 0.6, to 2% of newborns in France and an early detection allows an easy and successful treatment. The current situation in our country is not satisfactory for several reasons: - Too many children are treated without reasons because of misleading radiological pictures; - Conversely, some dislocations are discovered only at the walking age, the treatment becoming then more difficult and less effective; - Almost 300,000 radiological examinations of the hip for screening are performed each year and among them 100,000 in newborns. This is not satisfactory as it is commonly admitted now that radiological examination at birth is unreliable and frequently misleading. For all these reasons a special working group has been settled up by the General Direction of Health, including physicians of different practices, from different specialities. The conclusion of this group will be published in a special booklet and can be summarized as follows: The group recommends to perform detection of congenital hip dislocation mainly by the clinical examination. This examination may be difficult but it must be performed very early, the first day of life, repeated several times, at the end of the first week and during the first, second, and third month. Every baby in this country must undergo several clinical examinations up to one year of age

  5. Potentially lethal damage and its repair

    1989-01-01

    Two forms termed fast-and slow-potentially lethal lethal damage (PLD) are introduced and discussed. The effect on the survival of x-irradiated Chinese hamster cells (V79) of two different post-treatments is examined in plateau- and in log-phases of growth. The postirradiation treatments used : a) incubation in hypertonic solution, and b) incubation in conditioned medium obtained from plateau-phase. Similar reduction in survival was caused by postirradiation treatment with hypertonic phosphate buffered saline, and similar increased in survival was effected by treatment in conditioned medium in plateau- and in log-phases cells. However, repair of PLD sensitive to hypertonic treatment was faster (half time, 5-10 min)(f-PLD repair) and independent from the repair of PLD (half time, 1-2 hour)(s-PLD repair) observed in conditioned medium. The results indicate the induction of two forms of PLD by radiation. Induction of both PLD was found to decrease with increasing LET of the radiation used. Identification of the molecular processes underlying repair and fixation of PLD is a task of particular interest, since it may allow replacement of a phenomenological definition with a molecular definition. Evidence is reviewed indicating the DNA double strand breaks (directly or indirectly induced) may be the DNA lesions underlying PLD. (author)

    Background: Identifying genes that are essential for mouse embryonic development and survival through term is a powerful and unbiased way to discover possible genetic determinants of human developmental disorders. Characterising the changes in mouse embryos that result from ablation of lethal genes is a necessary first step towards uncovering their role in normal embryonic development and establishing any correlates amongst human congenital abnormalities. Methods: Here we present results gathered to date in the Deciphering the Mechanisms of Developmental Disorders (DMDD) programme, cataloguing the morphological defects identified from comprehensive imaging of 220 homozygous mutant and 114 wild type embryos from 42 lethal and subviable lines, analysed at E14.5. Results: Virtually all mutant embryos show multiple abnormal phenotypes and amongst the 42 lines these affect most organ systems. Within each mutant line, the phenotypes of individual embryos form distinct but overlapping sets. Subcutaneous edema, malformations of the heart or great vessels, abnormalities in forebrain morphology and the musculature of the eyes are all prevalent phenotypes, as is loss or abnormal size of the hypoglossal nerve. Conclusions: Overall, the most striking finding is that no matter how profound the malformation, each phenotype shows highly variable penetrance within a mutant line. These findings have challenging implications for efforts to identify human disease correlates. PMID:27996060

    Thirteen newborns with lethal short rib-polydactyly (SRP) have been reviewed, 11 with SRP type 3 (Verma-Naumoff) and 2 with SRP tye 2 (Majewski). In the former group there were three sets of siblings. The excess of males with SRP type III (Verma-Naumoff) is confirmed in this present study. A high frequency of phenotypic females including sex-reversed constitutional males with SRP type 1 (Saldino-Noonan) is in marked contrast to these findings in SRP type 3. Possible hypotheses include variable expressivity in non-Majewski short rib-polydactyly syndromes with sex-reversed and constitutional female cases tending to show more severe phenotypic expression both in terms of major anomalies and skeletal dysplastic effects.

  10. Lethal domestic violence in eastern North Carolina.

    Strategies for preventing domestic violence can be tailored to a particular geographic or socioeconomic area if the patterns of domestic violence in the area are known. National statistics, although widely available, may not be applicable to a specific region. We reviewed homicide deaths in Eastern North Carolina between 1978 and 1999 to identify patterns in this rural area. Approximately 20% of the homicide deaths in eastern North Carolina are caused by intimate partners. Women accounted for 53% of the victims in 1976, similar to national figures but not rising to 72% as seen nationally in 1998. Latinos are an increasing presence in the area, but had only one recorded episode of lethal violence against an intimate partner. Gunshots accounted for most of the deaths (59% in men, 72% in women). Knowledge of such patterns can assist in selecting prevention strategies for this particular area. Over the last 25 years increasing attention has been devoted to domestic violence (DV), initially defined as abuse committed against a spouse, former spouse, fiancée, boy- or girlfriend, or cohabitant. As time has passed, the definition has been broadened to include other family members--elders, children, and siblings. The Centers for Disease Control and Prevention (CDC) now uses the term "intimate partner violence" for intentional emotional or physical abuse inflicted by a spouse, ex-spouse, a present or former boy- or girlfriend, or date. For the purposes of this paper, we consider DV interchangeable with intimate partner violence. There has been a national concern that abusive events are under-reported. The National Crime Victimization Survey, an anonymous household survey, indicated nearly 1 million incidents of non-lethal intimate partner violence per year between 1992 and 1996. The number decreased from 1.1 million in 1993 to 840,000 in 1996. Attempts to validate such data for a given geographic area often require subjects to violate anonymity--this may account for lower

    Recent studies have reported an increase in the number of fetuses and neonates with microcephaly whose mothers were infected with the Zika virus (ZIKV) during pregnancy. To our knowledge, most reports to date have focused on select aspects of the maternal or fetal infection and fetal effects. To describe the prenatal evolution and perinatal outcomes of 11 neonates who had developmental abnormalities and neurological damage associated with ZIKV infection in Brazil. We observed 11 infants with congenital ZIKV infection from gestation to 6 months in the state of Paraíba, Brazil. Ten of 11 women included in this study presented with symptoms of ZIKV infection during the first half of pregnancy, and all 11 had laboratory evidence of the infection in several tissues by serology or polymerase chain reaction. Brain damage was confirmed through intrauterine ultrasonography and was complemented by magnetic resonance imaging. Histopathological analysis was performed on the placenta and brain tissue from infants who died. The ZIKV genome was investigated in several tissues and sequenced for further phylogenetic analysis. Description of the major lesions caused by ZIKV congenital infection. Of the 11 infants, 7 (63.6%) were female, and the median (SD) maternal age at delivery was 25 (6) years. Three of 11 neonates died, giving a perinatal mortality rate of 27.3%. The median (SD) cephalic perimeter at birth was 31 (3) cm, a value lower than the limit to consider a microcephaly case. In all patients, neurological impairments were identified, including microcephaly, a reduction in cerebral volume, ventriculomegaly, cerebellar hypoplasia, lissencephaly with hydrocephalus, and fetal akinesia deformation sequence (ie, arthrogryposis). Results of limited testing for other causes of microcephaly, such as genetic disorders and viral and bacterial infections, were negative, and the ZIKV genome was found in both maternal and neonatal tissues (eg, amniotic fluid, cord blood, placenta, and

    Full Text Available Congenital hepatic fibrosis is a rare cause of portal hypertension and esophageal varices in children. We report cases of siblings with biopsy proven congenital hepatic fibrosis and with atypical retinitis pigmentosa. They presented with repeated episodes of jaundice along with progressive decrease of vision in night. They had hepatosplenomegaly and portal hypertension with esophageal varices. One of the siblings had a large regenerating nodule replacing the entire right lobe of the liver and other one developed repeated hematemesis. This constellation of diagnosis belongs to the ciliopathy group of disorders. The spectrum of ciliopathy disorders has been evolving, and it varies from mild to severe manifestations.

    Neonatal congenital infections are an important cause of mortality, morbidity and long-term neurodevelopmental and sensorineural sequelae. Many pathogens can cause in utero infection, and among them, cytomegalovirus (CMV) plays a prominent role. In developed countries, CMV poses major health problems as it is the most common pathogen leading to congenital infection, and the leading cause of nonhereditary deafness in children. Evaluation of central nervous system (CNS) involvement in congenital CMV infected newborns is mandatory to better assess the severity of the disease, to guide adequate treatment, to define prognosis, and to tailor follow-up observations and parents' counselling. Cerebral ultrasonography (cUS), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) are the currently available techniques to evaluate infants with suspected or proven congenital CMV infection. In congenital CMV infection, their role in early detection and confirmation of cerebral involvement within the first month of life is crucial to initiate specific treatment with antivirals. Neonatologists, paediatricians and radiologists should be aware of the role, the limitations and the inherent risks related to the use of these specific neuroimaging diagnostic tools in these infants. In this article we will discuss from a neonatological perspective the advantages, disadvantages, risks and limitations of each imaging technique. Copyright © 2012 Elsevier Ireland Ltd.

    The prevention of congenital toxoplasmosis is based on providing information to women, serologic diagnosis and treatment of the infected mother and child. In this article we present the results of 12 years of implementation of a congenital toxoplasmosis prevention program in which we measured the mother's infection incidence rate, the transmission rate and the number and severity of infection in newborns. The study was performed on 12035 pregnant women in the period 2000-2011. The prevalence rate of antibodies against Toxoplasma gondii was 18.33% (2206/12035). Thirty-seven out of 9792 susceptible women presented acute infection and the mother's infection incidence rate was 3.78 per 1000 births. The transplacental transmission rate was 5.4% (2/37). Two newborns presented congenital toxoplasmosis infection, one had no clinical signs while the other presented strabismus and chorioretinitis. Thirty-five infected mothers and the two children with congenital infection were treated. The transmission rates obtained allow consider this prevention program as a valid resource to minimize the impact of congenital toxoplasmosis.

    Pathogenic Leptospira species adapt to a wide range of environmental conditions during disease transmission and infection. While the proteome of in vitro cultivated Leptospira has been characterized in several studies to date, relatively little is known of the proteome as expressed by Leptospira during disease processes. Isolates of Leptospira obtained from patients suffering the severe pulmonary form of leptospirosis cause acute lethal infection in guinea pigs and chronic asymptomatic infect...

    Full Text Available Abstract Background Synthetic lethality experiments identify pairs of genes with complementary function. More direct functional associations (for example greater probability of membership in a single protein complex may be inferred between genes that share synthetic lethal interaction partners than genes that are directly synthetic lethal. Probabilistic algorithms that identify gene modules based on motif discovery are highly appropriate for the analysis of synthetic lethal genetic interaction data and have great potential in integrative analysis of heterogeneous datasets. Results We have developed Genetic Interaction Motif Finding (GIMF, an algorithm for unsupervised motif discovery from synthetic lethal interaction data. Interaction motifs are characterized by position weight matrices and optimized through expectation maximization. Given a seed gene, GIMF performs a nonlinear transform on the input genetic interaction data and automatically assigns genes to the motif or non-motif category. We demonstrate the capacity to extract known and novel pathways for Saccharomyces cerevisiae (budding yeast. Annotations suggested for several uncharacterized genes are supported by recent experimental evidence. GIMF is efficient in computation, requires no training and automatically down-weights promiscuous genes with high degrees. Conclusion GIMF effectively identifies pathways from synthetic lethality data with several unique features. It is mostly suitable for building gene modules around seed genes. Optimal choice of one single model parameter allows construction of gene networks with different levels of confidence. The impact of hub genes the generic probabilistic framework of GIMF may be used to group other types of biological entities such as proteins based on stochastic motifs. Analysis of the strongest motifs discovered by the algorithm indicates that synthetic lethal interactions are depleted between genes within a motif, suggesting that synthetic

    2012-06-01

    Here we describe the first documented case of congenital amusia in childhood. AS is a 10-year-old girl who was referred to us by her choir director for persisting difficulties in singing. We tested her with the child version of the Montreal Battery for the Evaluation of Amusia (MBEA) which confirmed AS's severe problems with melodic and rhythmic discrimination and memory for melodies. The disorder appears to be limited to music since her audiometry as well as her intellectual and language skills are normal. Furthermore, the musical disorder is associated to a severe deficit in detecting small pitch changes. The electrical brain responses point to an anomaly in the early stages of auditory processing, such as reflected by an abnormal mismatch negativity (MMN) response to small pitch changes. In singing, AS makes more pitch than time errors. Thus, despite frequent and regular musical practice, AS's profile is similar to the adult form of congenital amusia. Copyright © 2011 Elsevier Srl.

    2017-10-01

    Full Text Available Summary: Myotonic dystrophy types 1 (DM1 and 2 (DM2 are dominantly inherited neuromuscular disorders caused by a toxic gain of function of expanded CUG and CCUG repeats, respectively. Although both disorders are clinically similar, congenital myotonic dystrophy (CDM, a severe DM form, is found only in DM1. CDM is also characterized by muscle fiber immaturity not observed in adult DM, suggesting specific pathological mechanisms. Here, we revealed upregulation of the interleukin-6 (IL-6 myokine signaling pathway in CDM muscles. We also found a correlation between muscle immaturity and not only IL-6 expression but also expanded CTG repeat length and CpG methylation status upstream of the repeats. Aberrant CpG methylation was associated with transcriptional dysregulation at the repeat locus, increasing the toxic RNA burden that upregulates IL-6. Because the IL-6 pathway is involved in myocyte maturation and muscle atrophy, our results indicate that enhanced RNA toxicity contributes to severe CDM phenotypes through aberrant IL-6 signaling. : Congenital myotonic dystrophy (CDM manifests characteristic genetic (very large CTG repeat expansions, epigenetic (CpG hypermethylation upstream of the repeat, and phenotypic (muscle immaturity features not seen in adult DM. Nakamori et al. find phenotype-genotype and epigenotype correlation in CDM muscle and reveal involvement of the IL-6 myokine signaling pathway in the disease process.

    In an unselected and consecutive series of 1858 newborn infants of diabetic mothers, born in the Rigshospital, Copenhagen, in the period 1967 to 1986, congenital malformations were studied. The malformation rate in White Classes B to F was remarkably constant from 1967 to 1981, but a significant...... decrease in major congenital malformations was found in the period 1982 to 1986 versus 1977 to 1981 (2.7% vs. 7.4%, p less than 0.05). This decrease was mainly due to a fourfold decline in major congenital malformations in White Classes D and F (p less than 0.01), and consequently a correlation between...... the severity of maternal diabetes and the frequency of congenital malformations was no longer present. In the offspring of a control group of 1715 nondiabetic women, major congenital malformations were found in 1.7% (p greater than 0.05).

    Zika virus (ZIKV) is a mosquito-borne arbovirus from the Flaviviridae family. It had caused several epidemics since its discovery in 1947, but there was no significant attention to this virus until the recent outbreak in Brazil in 2015. The main concern is the causal relationship between prenatal ZIKV infection and congenital microcephaly, which has been confirmed recently. Moreover, ZIKV may cause other central nervous system abnormalities such as brain parenchymal atrophy with secondary ventriculomegaly, intracranial calcification, malformations of cortical development (such as polymicrogyria, and lissencephaly-pachygyria), agenesis/hypoplasia of the corpus callosum, cerebellar and brainstem hypoplasia, sensorineural hearing-loss, and ocular abnormalities as well as arthrogryposis in the infected fetuses. Postnatal (acquired) ZIKV infection usually has an asymptomatic or mildly symptomatic course, while prenatal (congenital) ZIKV infection has a more severe course and may cause severe brain anomalies that are described as congenital Zika syndrome. In this pictorial essay, we aim to illustrate the prenatal and postnatal neuroimaging findings that may be seen in fetuses and neonates with congenital Zika syndrome, and will discuss possible radiological differential diagnoses. A detailed knowledge of these findings is paramount for an early correct diagnosis, prognosis determination, and counseling of the affected children and families.

    In order to clarify the CT findings of lethal midline granuloma (LMG) diagnosed clinically or histopathologically, the authors retrospectively analyzed 12 patients who were seen at Kyungpook National University Hospital from February 1985 to August 1989. CT showed nasal mucosal thickening and / or soft tissue mass (9 case), spreading of the lesions along the facial subcutaneous fat plane (8 cases), invasion into the paranasal sinuses (5 cases), bone destruction (5 cases), nasopharyngeal mass lesion (2 cases), and extension of the lesion into the infratemporal fossa (1 case). In spite of the fact that CT does not make definitive diagnosis of LMG, it permits evaluation of the extent of the lesion, detection of the combined lesion, differential diagnosis, and close monitoring of its evolution under treatment

    The in vivo incorporation of U- 14 C-alanine into blood glucose and liver glycogen was measured in rats irradiated with a single whole body lethal dose of X-rays. Changes in gluconeogenic enzyme activities were studied in the liver. Increased incorporation of 14 C-alanine into blood glucose and liver glycogen were found after irradiation. Liver phosphoenolpyruvate carboxykinase and glycogenic activity underwent almost parallel changes and were significantly elevated from the 6th to the 48th hour, with resultant accumulation of glycogen. Glucose-6-phosphatase activity was depressed and there was a negative correlation between it and liver glycogen concentration. Maximum fructose-1,6-diphosphatase activity was found at 48 hours. The results show that glycogen accumulation in the liver and the raised blood glucose level in X-irradiated rats are based on raised gluconeogenesis. (author)

    2010-01-01

    Social insects defend their own colonies and some species also protect their mutualist partners. In mutualisms with aphids, ants typically feed on honeydew produced by aphids and, in turn guard and shelter aphid colonies from insect natural enemies. Here we report that Formica podzolica ants tending milkweed aphids, Aphis asclepiadis, protect aphid colonies from lethal fungal infections caused by an obligate aphid pathogen, Pandora neoaphidis. In field experiments, bodies of fungal-killed aphids were quickly removed from ant-tended aphid colonies. Ant workers were also able to detect infective conidia on the cuticle of living aphids and responded by either removing or grooming these aphids. Our results extend the long-standing view of ants as mutualists and protectors of aphids by demonstrating focused sanitizing and quarantining behaviour that may lead to reduced disease transmission in aphid colonies.

  7. Lethal photosensitization of biofilm-grown bacteria

    Science.gov (United States)

    Wilson, Michael

    1997-12-01

    Antibacterial agents are increasingly being used for the prophylaxis and treatment of oral diseases. As these agents can be rendered ineffective by resistance development in the target organisms there is a need to develop alternative antimicrobial approaches. Light-activated antimicrobial agents release singlet oxygen and free radicals which can kill adjacent bacteria and a wide range of cariogenic and periodontopathogenic bacteria has been shown to be susceptible to such agents. In the oral cavity these organisms are present as biofilms (dental plaques) which are less susceptible to traditional antimicrobial agents than bacterial suspensions. The results of these studies have shown that biofilm-grown oral bacteria are also susceptible to lethal photosensitization although the light energy doses required are grater than those needed to kill the organisms when they are grown as aqueous suspensions.

    Advances in the field of antenatal diagnosis have made possible the detection of profound sensorineural hearing loss prior to birth. Fetal motion in response to sound and auditory evoked potential testing can determine the presence of fetal hearing in the third trimester of pregnancy. Imaging modalities including ultrasound, computed tomography, and magnetic resonance imaging hold promise for the diagnosis of some forms of congenital deafness in the second trimester fetus. The methods by which congenital deafness soon may be diagnosed and the implications for the otologist are discussed.

    Chemical manifestations are considered and CT-semiotics of congenital toxoplasmosis, which can form intracranial calcinates, is described. Taking a certain case of congenital toxoplasmosis observation as an example the potentialities and significance of X-ray computerized tomography (CT) in the identification of brain pathological changes are demonstrated. It is shown that intracranial calcificates may be a sign of toxoplasmosis infection. In case of cytomegalovirus infection the calcificates on CT-scans have mostly periventricular localization. Equally with the revealing of brain status in case of chronic stage of neutrotoxoplasmosis the CT has also played a decisive role in diagnosis of pseudotumoroseus course of ischemic insult [ru

    We present the MRI features of a congenital urethroperineal fistula diagnosed in a 12-year-old boy being evaluated after a single urinary tract infection. This diagnosis was initially suggested by voiding cystourethrogram and confirmed by MRI. Imaging revealed an abnormal fluid-filled tract arising from the posterior urethra and tracking to the perineal skin surface that increased in size during micturition. Surgical resection and histopathological evaluation of the abnormal tract confirmed the diagnosis of congenital urethroperineal fistula. MRI played important roles in confirming the diagnosis and assisting surgical planning. (orig.)

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

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

  16. The lethal injection quandary: how medicine has dismantled the death penalty.

    Science.gov (United States)

    Denno, Deborah W

    2007-10-01

    On February 20, 2006, Michael Morales was hours away from execution in California when two anesthesiologists declined to participate in his lethal injection procedure, thereby halting all state executions. The events brought to the surface the long-running schism between law and medicine, raising the question of whether any beneficial connection between the professions ever existed in the execution context. History shows it seldom did. Decades of botched executions prove it. This Article examines how states ended up with such constitutionally vulnerable lethal injection procedures, suggesting that physician participation in executions, though looked upon with disdain, is more prevalent--and perhaps more necessary--than many would like to believe. The Article also reports the results of this author's unique nationwide study of lethal injection protocols and medical participation. The study demonstrates that states have continued to produce grossly inadequate protocols that severely restrict sufficient understanding of how executions are performed and heighten the likelihood of unconstitutionality. The analysis emphasizes in particular the utter lack of medical or scientific testing of lethal injection despite the early and continuous involvement of doctors but ongoing detachment of medical societies. Lastly, the Article discusses the legal developments that led up to the current rush of lethal injection lawsuits as well as the strong and rapid reverberations that followed, particularly with respect to medical involvement. This Article concludes with two recommendations. First, much like what occurred in this country when the first state switched to electrocution, there should be a nationwide study of proper lethal injection protocols. An independent commission consisting of a diverse group of qualified individuals, including medical personnel, should conduct a thorough assessment of lethal injection, especially the extent of physician participation. Second, this

    Full Text Available Understanding the sedimentation and turbidity thresholds for corals is critical in assessing the potential impacts of dredging projects in tropical marine systems. In this study, we exposed two species of coral sampled from offshore locations to six levels of total suspended solids (TSS for 16 weeks in the laboratory, including a 4 week recovery period. Dose-response relationships were developed to quantify the lethal and sub-lethal thresholds of sedimentation and turbidity for the corals. The sediment treatments affected the horizontal foliaceous species (Montipora aequituberculata more than the upright branching species (Acropora millepora. The lowest sediment treatments that caused full colony mortality were 30 mg l(-1 TSS (25 mg cm(-2 day(-1 for M. aequituberculata and 100 mg l(-1 TSS (83 mg cm(-2 day(-1 for A. millepora after 12 weeks. Coral mortality generally took longer than 4 weeks and was closely related to sediment accumulation on the surface of the corals. While measurements of damage to photosystem II in the symbionts and reductions in lipid content and growth indicated sub-lethal responses in surviving corals, the most reliable predictor of coral mortality in this experiment was long-term sediment accumulation on coral tissue.

    Ionizing radiation-induced myeloablation can be rescued via bone marrow transplantation (BMT) or administration of cytokines if given within 2 hours after radiation exposure. There is no evidence for the existence of soluble factors that can rescue an animal after a lethal dose of radiation when administered several hours postradiation. We established a system that could test the possibility for the existence of soluble factors that could be used more than 2 hours postirradiation to rescue animals. Animals with an implanted TheraCyte immunoisolation device (TID) received lethal-dose radiation and then normal bone marrow Lin- cells were loaded into the device (thereby preventing direct interaction between donor and recipient cells). Animal survival was evaluated and stem cell activity was tested with secondary bone marrow transplantation and flow cytometry analysis. Donor cell gene expression of five antiapoptotic cytokines was examined. Bone marrow Lin- cells rescued lethally irradiated animals via soluble factor(s). Bone marrow cells from the rescued animals can rescue and repopulate secondary lethally irradiated animals. Within the first 6 hours post-lethal-dose radiation, there is no significant change of gene expression of the known radioprotective factors TPO, SCF, IL-3, Flt-3 ligand, and SDF-1. Hematopoietic stem cells can be protected in lethally irradiated animals by soluble factors produced by bone marrow Lin- cells.

  1. The Return of Congenital Rickets, Are We Missing Occult Cases?

    Congenital rickets is the term given to fetus born with clinical features of rickets, but those born with biochemical evidence of rickets without obvious clinical features still can be considered occult congenital rickets. Some of the affected babies with this disease have the intrauterine rachitic environment, but a calcium trans-placental pump prevents the fetus from having clinical features of rickets. They may present with hypocalcemia few days after birth or later with more florid features of rickets. Congenital rickets cases born with florid features reported over the last 40 years are few and can be divided into two groups. The first due to severe maternal osteomalacia in which their bones were so decalcified to have enough calcium to be pumped to their fetus. Another group in which newborn babies were hypocalcemic due to other maternal diseases as malabsorption, celiac disease, pre-eclampsia, and prematurity. All inherited rickets cases per se, or as part of other syndromes can be considered congenital rickets. Most cases seen in our region are due to maternal vitamin D deficiency with symptoms becoming obvious when the infants are breastfed, or may present with hypocalcemic convulsions or craniotabes. This is a review of congenital rickets with the aim of shedding light on this potentially acute disease that needs more attention and awareness in the neonatal period to avoid rare serious complications as cardiomyopathy or myelofibrosis and the complications of hypocalcemic convulsions. Congenital rickets cases seen simulate a tip of an ice-burg and its prevention is an important issue, especially with the tremendous urbanization with tall buildings living in sun-deprived flats as the commonest type of residence leading to the increasing incidence of maternal osteomalacia and rickets.

    The diagnosis of congenital hypopituitarism is difficult and often delayed because its symptoms are nonspecific. To describe the different clinical presentations of children with congenital hypopituitarism to reduce the time for diagnosis and to begin a precocious and appropriate treatment. We analyzed a cohort of five children with congenital hypopituitarism, describing their clinical, biochemical and radiological characteristics from the birth to diagnosis. As first sign of the disease, all of five patients presented a neonatal hypoglycemia, associated in four cases with jaundice. In all these four cases, the clinicians hypothesized a metabolic disease delaying the diagnosis, which was performed in only two cases within the neonatal period. In the other three cases, the diagnosis was formulated at 2, 5 and 8 years of life because there was severe and precocious growth impairment. It is important to suspect congenital hypopituitarism in the presence of persistent neonatal hypoglycemia associated with jaundice and of a precocious and severe reduction of the growth velocity in childhood. In all these cases, it is necessary to undertake a hypothalamic-pituitary magnetic resonance imaging scan as soon as possible, and to start appropriate treatment.

    Developmental genetics of congenital heart diseases has evolved from analysis of serial slices in embryos towards molecular genetics of cardiac morphogenesis with a dynamic view of cardiac development. Genetics of congenital heart diseases has also changed from formal genetic analysis of familial recurrences or population-based analysis to screening for mutations in candidates genes identified in animal models. Close cooperation between molecular embryologists, pathologists involved in heart development and pediatric cardiologists is crucial for further increase of knowledge in the field of cardiac morphogenesis and genetics of cardiac defects. The genetic model for congenital heart disease has to be revised to favor a polygenic origin rather than a monogenic one. The main mechanism is altered genic dosage that can account for heart diseases in chromosomal anomalies as well as in point mutations in syndromic and isolated congenital heart diseases. The use of big data grouping information from cardiac development, interactions between genes and proteins, epigenetic factors such as chromatin remodeling or DNA methylation is the current source for improving our knowledge in the field and to give clues for future therapies.

    We used the theory of reasoned action to help understand attitudes and beliefs about lethal management of deer (Odocoileus virginianus) in Cuyahoga Valley National Park (CVNP), Ohio. We used a mail-back survey to collect data from Ohio residents in the surrounding 9-county area. Two strata were defined: residents control of deer was acceptable (near 71%??4.7%, far 62%??5.5%) and taking no action to reduce deer populations was unacceptable (near 75%??4.5%, far 72%??5.1%). Beliefs about outcomes of lethal control and evaluation of those outcomes proved to be strong predictors of the acceptability of lethal control of deer in CVNP. Lethal control was more acceptable if it was done to prevent severe consequences for humans (e.g., spread of disease, car collisions) or the natural environment (e.g., maintain a healthy deer herd) than to prevent negative aesthetic impacts or personal property damage. Results from the study can be used to assist managers at CVNP as they make decisions regarding alternatives for deer management in the park and to inform others managing abundant deer populations of socially relevant impacts of management actions.

    2016-01-01

    Congenital hemolytic anemia is a group of monogenic diseases presenting with anemia due to increased destruction of circulating erythrocytes. The etiology of inherited anemia accounts for germline mutations of the responsible genes coding for the structural components of erythrocytes and extra-erythrocytes. The erythrocyte abnormalities are classified into three major disorders of red cell membrane defects, hemoglobinopathies, and red cell enzymopathies. The extra-erythrocyte abnormalities, typified by consumption coagulopathy and intravascular hemolysis, include Upshaw-Schulman syndrome and atypical hemolytic uremic syndrome. The clinical manifestations of congenital hemolytic anemia are anemia, jaundice, cholelithiasis and splenomegaly, while the onset mode and severity are both variable. Genetic overlapping of red cell membrane protein disorders, and distinct frequency and mutation spectra differing among races make it difficult to understand this disease entity. On the other hand, genetic modifiers for the phenotype of β-globin diseases provide useful information for selecting the optimal treatment and for long-term management. Recently, next generation sequencing techniques have enabled us to determine the novel causative genes in patients with undiagnosed hemolytic anemias. We herein review the concept and strategy for genetic diagnosis of inherited hemolytic anemias.

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

    We used data from a population-based case-control study to explore the relation between certain life events during the periconceptional period and several types of congenital anomalies. We ascertained cases from pregnancies ending in 1987-1989 and randomly selected controls from eligible liveborn infants. In telephone interviews, women reported deaths of anyone close to them. They also reported job losses or separations/divorces, for themselves or anyone close to them. Experiencing at least one stressful event during the periconceptional period was associated with a prevalence odds ratio of 1.4-1.5 for the delivery of infants with conotruncal heart defects, neural tube defects, and isolated cleft lip with or without palate. These associations tended to be restricted to women who were not obese and women with less than or equal to a high school education. This study suggests that women who experience stressful life events around the time of conception or early gestation may be at increased risk of delivering infants with certain congenital anomalies.

  17. Adult Congenital Heart Disease with Pregnancy

    Science.gov (United States)

    2018-01-01

    The number of women with congenital heart disease (CHD) at risk of pregnancy is growing because over 90% of them are grown-up into adulthood. The outcome of pregnancy and delivery is favorable in most of them provided that functional class and systemic ventricular function are good. Women with CHD such as pulmonary hypertension (Eisenmenger syndrome), severe left ventricular outflow stenosis, cyanotic CHD, aortopathy, Fontan procedure and systemic right ventricle (complete transposition of the great arteries [TGA] after atrial switch, congenitally corrected TGA) carry a high-risk. Most frequent complications during pregnancy and delivery are heart failure, arrhythmias, bleeding or thrombosis, and rarely maternal death. Complications of fetus are prematurity, low birth weight, abortion, and stillbirth. Risk stratification of pregnancy and delivery relates to functional status of the patient and is lesion specific. Medication during pregnancy and post-delivery (breast feeding) is a big concern. Especially prescribing medication with teratogenicity should be avoidable. Adequate care during pregnancy, delivery, and the postpartum period requires a multidisciplinary team approach with cardiologists, obstetricians, anesthesiologists, neonatologists, nurses and other related disciplines. Caring for a baby is an important issue due to temporarily pregnancy-induced cardiac dysfunction, and therefore familial support is mandatory especially during peripartum and after delivery. Timely pre-pregnancy counseling should be offered to all women with CHD to prevent avoidable pregnancy-related risks. Successful pregnancy is feasible for most women with CHD at relatively low risk when appropriate counseling and optimal care are provided. PMID:29625509

    Although congenital talipes equinovarus (CTEV) is one of the most frequently occurring congenital defects of locomotor organs, its ethiopathogenesis is still not fully known. Amongst the others, the inheritance patterns of that defect are not fully known, and that restricts genetic therapeutics and development of new treatment technologies. The aim of this study was analysis of family lineages of 205 children with CTEV (298 feet) treated at our centre in the years 1998-2008. The family occurrence of CTEV was found in 16 cases (8% of analysed group). 6 lineages, in which CTEV occurred in successive generations, were analysed in detail. Particularly interesting is the lineage of the family 1, in which the defect occurred in three successive generations. In case of that family, an autosomal dominant inheritance pattern is possible. Previously that pattern of CTEV inheritance was described only for isolated populations of Polynesians. In own material the family occurrence of CTEV was found to be less frequent than in bibliographic references. The defect occurred twice as often in boys, while the severe form was more frequently observed in girls, and that is consisted with data in the available bibliography. The analysis of presented lineages of families with CTEV did not allow unambiguous defining of the inheritance pattern for that defect. To confirm the autosomal dominant pattern of CTEV inheritance in the family in which the defect occurred in three successive generations, genetic tests would be necessary.

    Full Text Available Background: It is challenging to manage congenital blepharoptosis, especially unilateral, because symmetry is difficult to achieve under general anesthesia and age at which the ptosis should be corrected is still controversial. The aim of our study is to analyze visual and surgical outcomes after levator resection for unilateral congenital blepharoptosis. Methods: Charts of patients with unilateral congenital blepharoptosis who underwent levator resection at the Chang Gung Memorial Hospital from 1991 through 2000 were reviewed. The resultant database was interrogated for demographic data, severity, surgical timing, visual outcomes, surgical outcomes, and complications. Results: Eighty-four children underwent levator resection for unilateral congenital blepharoptosis: 16.7% of these patients had amblyopia and 84.5% had surgical success following levator resection. Severe ptosis (p = 0.0288, p < 0.05 and surgery at less than 2 years of age (p = 0.0126, p < 0.05 were the important factors contributing to surgical failure. Age at surgery (p = 0.0058, p < 0.01 and amblyogenic ametropia (p = 0.0001, p < 0.001 were found to be significantly associated with the postoperative visual results. Conclusion: The levator resection provides satisfactory results both in function and cosmesis in patients with unilateral congenital blepharoptosis. Amblyogenic ametropia is the leading cause of amblyopia in the patients with unilateral isolated congenital blepharoptosis. However, patients with unilateral congenital blepharoptosis should have cycloplegic refraction as early as possible, and their visual status monitored until visual maturity.

    According to WHO hereditary diseases and congenital malformations contribute significantly to the health of population. Thus, the problems of epidemiology, clinical presentation, diagnosis and treatment of congenital abnormalities are of interest for many researchers [2]. In addition, the dynamic accounting for the incidence of congenital malformations and hereditary diseases allows the researchers to assess the ecological situation in the region [1]. The occurrence of congenital anomalies in the world varies; it depends heavily on how carefully the data is collected [4]. Multifactorial or polygenic diseases develop under the influence of environmental factors in the presence of defective genes. They can constitute up to 90% of all chronic pathology [2-5]. To determine the incidence of congenital anomalies under the influence of environmental factors. The study used the methodology of system evaluation of congenital anomalies incidence in Primorsky region, depending on bio-climatic and environmental conditions. The authors used health statistics for the period from 2000 to 2014, F.12 class for congenital abnormalities in adolescents and children that were compared in geographical and temporal aspects with environmental factors of 33 settlements in Primorsky region. The environment is represented by nature and climate (6 factor modules) and sanitation (7 factor modules) blocks of factors. When formalizing the information database of the environment a specially developed 10-point assessment scale was used. Statistical processing of the information was carried out using Pearson's chi-squared test and multiple regression method from SSPS application program package. The study found that over the 15-year period the level of congenital abnormalities in children increased by 27.5% and in adolescents - by 35.1%, and in 2014 it amounted to 1687.6 and 839.3 per 100 000 people, respectively. The predictive model shows a steady further growth of this pathology. The incidence

    Atrioventricular block is classified as congenital if diagnosed in utero, at birth, or within the first month of life. The pathophysiological process is believed to be due to immune-mediated injury of the conduction system, which occurs as a result of transplacental passage of maternal anti-SSA/Ro-SSB/La antibodies. Childhood atrioventricular block is therefore diagnosed between the first month and the 18th year of life. Genetic variants in multiple genes have been described to date in the pathogenesis of inherited progressive cardiac conduction disorders. Indications and techniques of cardiac pacing have also evolved to allow safe permanent cardiac pacing in almost all patients, including those with structural heart abnormalities. Early diagnosis and appropriate management are critical in many cases in order to prevent sudden death, and this review critically assesses our current understanding of the pathogenetic mechanisms, clinical course, and optimal management of congenital and childhood AV block. • Prevalence of congenital heart block of 1 per 15,000 to 20,000 live births. AV block is defined as congenital if diagnosed in utero, at birth, or within the first month of life, whereas childhood AV block is diagnosed between the first month and the 18th year of life. As a result of several different etiologies, congenital and childhood atrioventricular block may occur in an entirely structurally normal heart or in association with concomitant congenital heart disease. Cardiac pacing is indicated in symptomatic patients and has several prophylactic indications in asymptomatic patients to prevent sudden death. • Autoimmune, congenital AV block is associated with a high neonatal mortality rate and development of dilated cardiomyopathy in 5 to 30 % cases. What is New: • Several genes including SCN5A have been implicated in autosomal dominant forms of familial progressive cardiac conduction disorders. • Leadless pacemaker technology and gene therapy for

    "Krokodil" is a home-made opioid drug obtained by synthesizing desomorphine from codeine and combining it with other low-cost additives. Initially introduced in the former Soviet countries, it was then imported to Western Europe as a heroin substitute. To our knowledge, this is the first report of an Italian case of lethal krokodil abuse, that occurred in a 39-year-old man, who died suddenly after transportation to the Emergency Department (ED) for hyperthermia associated with sweating, dyspnoea and tachycardia. Post-mortem examination revealed extensive necrotic ulcerative lesions on the forearms, and autopsy showed a hypertrophic heart with ample endocardial vegetation on the aortic valve and patency of the foramen ovale. Histopathological examination of the heart showed ulcero-vegetative lesions of the aortic valve with an abscess on the annulus and extension to the periaortic adipose tissue, as well as diffuse myocardial interstitial inflammatory neutrophilic infiltrates. Toxicological analysis demonstrated a desomorphine metabolite in urine. On the basis of all these findings the cause of death was ruled to be congestive heart failure caused by endocarditis and myocarditis, correlated with chronic abuse of krokodil.

    It is unclear whether a single clone metastasizes and remains dominant over the course of lethal prostate cancer. We describe the clonal architectural heterogeneity at different stages of disease progression by sequencing serial plasma and tumor samples from 16 ERG-positive patients. By characterizing the clonality of commonly occurring deletions at 21q22, 8p21, and 10q23, we identified multiple independent clones in metastatic disease that are differentially represented in tissue and circulation. To exemplify the clinical utility of our studies, we then showed a temporal association between clinical progression and emergence of androgen receptor (AR) mutations activated by glucocorticoids in about 20% of patients progressing on abiraterone and prednisolone or dexamethasone. Resistant clones showed a complex dynamic with temporal and spatial heterogeneity, suggesting distinct mechanisms of resistance at different sites that emerged and regressed depending on treatment selection pressure. This introduces a management paradigm requiring sequential monitoring of advanced prostate cancer patients with plasma and tumor biopsies to ensure early discontinuation of agents when they become potential disease drivers.

    Why humans are prone to cooperate puzzles biologists, psychologists and economists alike. Between-group conflict has been hypothesized to drive within-group cooperation. However, such conflicts did not have lasting effects in laboratory experiments, because they were about luxury goods, not needed for survival ("looting"). Here, we find within-group cooperation to last when between-group conflict is implemented as "all-out war" (eliminating the weakest groups). Human subjects invested in helping group members to avoid having the lowest collective pay-off, whereas they failed to cooperate in control treatments with random group elimination or with no subdivision in groups. When the game was repeated, experience was found to promote helping. Thus, not within-group interactions alone, not random group elimination, but pay-off-dependent group elimination was found to drive within-group cooperation in our experiment. We suggest that some forms of human cooperation are maintained by multi-level selection: reciprocity within groups and lethal competition among groups acting together.

    Review of relevant literature including personal opinions. To review the current researches investigating the efficacy of growing rod and thoracic expansion techniques in the treatment of congenital spine deformity of young children, and to highlight the contrasting advantages and limitations in the fusionless treatment of progressive congenital scoliosis. Congenital scoliosis has the potential for severe spinal deformity and thoracic insufficiency syndrome (TIS). Conventional fusion treatments in children tend to shorten the spine further exacerbating trunk shortening and TIS. In the surgical treatment of congenital spinal deformities in young children, while reconstructing the spinal deformity, one should simultaneously pursue preserving the growth potential of the vertebrae, improving the volume, symmetry, and functions of the thorax, and protecting this improvement during the growth. Today, employed in the treatment of spinal deformities of young children, there are 2 deformity reconstruction methods serving these targets: Growing rod technique and vertical expandable prosthetic titanium rib (VEPTR) with or without expansion thoracostomy. Peer-reviewed research articles and major international meeting presentations were reviewed. Methods were compared in terms of advantages and limitations. The growing rod technique is a safe and reliable method in the treatment of congenital spine deformity of young children who present some flexibility in the anomalous segment, or when the congenital anomaly involves a vertebral segment too long for resection, or with compensating curve with structural pattern concomitant to the congenital deformity. Expansion thoracostomy and VEPTR are the appropriate choice for severe congenital spine deformity when a large amount of growth remains. Although ventilator dependence is significantly decreasing, thoracic volume and space available for the lung are increased after expansion thoracostomy and VEPTR. Growing rod technique should be

    Agricultural chemical inputs have been considered as a risk factor for the global declines in amphibian populations, yet the application of agricultural fungicides has increased dramatically in recent years. Currently little is known about the potential toxicity of fungicides on the embryos of amphibians. We studied the effects of ten commonly used fungicides (four strobilurins, two SDHIs, two triazoles, fludioxonil and folpet) on Xenopus tropicalis embryos. Lethal and teratogenic effects were respectively examined after 48 h exposure. The median lethal concentrations (LC50s) and the median teratogenic concentrations (TC50s) were determined in line with actual exposure concentrations. These fungicides except two triazoles showed obvious lethal effects on embryos; however LC50s of four strobilurins were the lowest and in the range of 6.81–196.59 μg/L. Strobilurins, SDHIs and fludioxonil induced severe malformations in embryos. Among the ten fungicides, the lowest TC50s were observed for four strobilurins in the range of 0.61–84.13 μg/L. The teratogenicity shared similar dose–effect relationship and consistent phenotypes mainly including microcephaly, hypopigmentation, somite segmentation and narrow fins. The findings indicate that the developmental toxicity of currently-used fungicides involved with ecologic risks on amphibians. Especially strobilurins are highly toxic to amphibian embryos at μg/L level, which is close to environmentally relevant concentrations. - Highlights: • Effects of ten agricultural fungicides were tested on Xenopus tropicalis embryos. • Strobilurin fungicides showed strong lethal and teratogenic effects on embryos. • Lowest LC50 and TC50 were observed for strobilurins in ten fungicides. • μg/L level of toxic concentrations for strobilurins was environmentally relevant. • Teratogenicity shared similar dose–effect relationship and main phenotypes. - Strobilurins induced strong lethality and teratogenicity on Xenopus

    Congenital glaucoma appears in the first months of life, eventually at birth. Isolated congenital glaucoma is characterized by minor malformations of the irido-corneal angle of the anterior chamber of the eye. Clinical manifestations include tearing, photophobia and enlargement of the globe appearing in the first months of life. Imaging technology such as optical coherence tomography and measurement of central corneal thickness may play an important role in the assessment of children with suspected or known glaucoma. However, no MRI findings of the CNS in patients with primary congenital glaucoma (PCG) were reported in the literature. The purpose of this study was to investigate MRI findings of the brain in infants with PCG. We reviewed the radiological and histopathological and clinical characteristics of infants with primary congenital glaucoma. The records of 17 patients with PCG were reviewed and the MRIs of the brain and associated manifestations were analyzed. Three patients with PCG had abnormal MRI findings suggesting agenesis of the corpus callosum. Two infants had delayed myelinization of the brain. Significant abnormal optic nerve excavation and increased corneal diameters in 2 patients with delayed myelinization may suggest that intraocular pressure can be more striking and more severe, revealing a close relationship with PCG and abnormal myelinization in white matter. Studies with more patients are needed to confirm these results. (author)

    Wolfram syndrome is characterized by optic atrophy, insulin dependent diabetes mellitus, diabetes insipidus and deafness. There are several other associated conditions reported in the literature, but congenital or early childhood cataracts are not among them. Observational case series with confirmatory genetic analysis. A pair of siblings, followed over 17 years, who manifest congenital or early childhood cataracts, diabetes insipidus, diabetes mellitus, optic atrophy, and deafness. They are both compound heterozygotes for mutations (V415 deletion and A684V substitution) in the WFS1 gene. Their father has congenital sensorineural hearing loss and developed optic atrophy. He is heterozygous for A684V in WFS1. Wolfram syndrome should be in the differential diagnosis of genetic syndromes associated with congenital and early childhood cataracts. Here, we report on a mother who is a phenotypically normal carrier of an autosomal recessive Wolfram syndrome gene, and a father who has some of the findings of the syndrome and carries a single mutation that appears to be responsible for his hearing loss and optic atrophy. Their 2 children are compound heterozygotes and manifest the full Wolfram syndrome, in addition to cataracts.

    Thallium-201 myocardial scintigraphy was performed in patients with congenital heart defects to determine whether, by quantification of right ventricular isotope uptake, one could assess the degree of right ventricular hypertrophy and so predict the level of right ventricular pressure. It is shown that quantitative analysis of myocardial imaging with thallium-201 is of use clinically in patients with congenital heart defects, in assessing the severity of pulmonary stenosis or the presence of pulmonary artery hypertension.

    1975-04-01

    This report analyzes the patterns in 54 lung scannings of 34 patients with altered pulmonary blood flow due to congenital heart disease. The technique and the results are presented. According to the images obtained, the patients are classified in three groups: Group I--normal distribution with more concentration of particles over the right lung and the bases. Group II--normal scannings found in left to right shunts unless there is pulmonary venous hypertension in which case the apex-base relationship was inverted. Group III--patients with right to left shunts of different types presenting various patterns according to severity, associated anomalies and palliative surgery. The hemodynamics created by cardiac defects and surgical procedures explain these alterations. This method is recommended in view of its advantages and accurate results.

    Full Text Available Congenital absence of left circumflex artery is a rare congenitalanomaly of the coronary arteries. The prevalence of theanomaly in different studies ranges from 0.6% to 1.3%. Ofthese, 80% are benign and asymptomatic and 20% are clinicallyimportant. We report a 56-year-old man presented withacute resting chest pain who was diagnosed as having acuteanterolateral infarction accompanied by electrocardiographicchanges and elevated cardiac enzymes. Coronary angiographyin different views was conducted, however, no left circumflexartery was found. The territory supplied by the artery had beenperfused by the super dominant right coronary artery. Therewas no left circumflex coronary artery with anomalous origin.Sever stenosis of left anterior ascending artery superimposedto the absent left circumflex artery was presented as acute anterolateralinfarction. Although absence of the artery is mostlyconsidered as a benign condition, atherosclerotic lesions maybe more important in such cases because of diminished compensatingmechanisms.

    2013-01-01

    Full Text Available Congenital adrenal hyperplasia (CAH describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge. Important long-term health issues for adults with CAH affect both men and women. These issues may either be due to the disease or to steroid treatment and may affect final height, fertility, cardiometabolic risk, bone metabolism, neuro-cognitive development and the quality-of-life. Patients with CAH should be regularly followed-up from childhood to adulthood by multidisciplinary teams who have knowledge of CAH. Optimal replacement therapy, close clinical and laboratory monitoring, early life-style interventions, early and regular fertility assessment and continuous psychological management are needed to improve outcome.

  19. Congenital diaphragmatic hernia-associated pulmonary hypertension.

    Science.gov (United States)

    Harting, Matthew T

    2017-06-01

    Congenital diaphragmatic hernia (CDH) is a complex entity wherein a diaphragmatic defect allows intrathoracic herniation of intra-abdominal contents and both pulmonary parenchymal and vascular development are stifled. Pulmonary pathology and pathophysiology, including pulmonary hypoplasia and pulmonary hypertension, are hallmarks of CDH and are associated with disease severity. Pulmonary hypertension (PH) is sustained, supranormal pulmonary arterial pressure, and among patients with CDH (CDH-PH), is driven by hypoplastic pulmonary vasculature, including alterations at the molecular, cellular, and tissue levels, along with pathophysiologic pulmonary vasoreactivity. This review addresses the basic mechanisms, altered anatomy, definition, diagnosis, and management of CDH-PH. Further, emerging therapies targeting CDH-PH and PH are explored.

    Christesen, Henrik Thybo; Brusgaard, Klaus; Alm, Jan

    2007-01-01

    BACKGROUND: In severe, medically unresponsive congenital hyperinsulinism (CHI), the histological differentiation of focal versus diffuse disease is vital, since the surgical management is completely different. Genetic analysis may help in the differential diagnosis, as focal CHI is associated...... with a paternal germline ABCC8 or KCNJ11 mutation and a focal loss of maternal chromosome 11p15, whereas a maternal mutation, or homozygous/compound heterozygous ABCC8 and KCNJ11 mutations predict diffuse-type disease. However, genotyping usually takes too long to be helpful in the absence of a founder mutation....... METHODS: In 4 patients, a rapid genetic analysis of the ABBC8 and KCNJ11 genes was performed within 2 weeks on request prior to the decision of pancreatic surgery. RESULTS: Two patients had no mutations, rendering the genetic analysis non-informative. Peroperative multiple biopsies showed diffuse disease...

    2012-03-01

    The cause of congenital talipes equinovarus (CTEV) is multifactorial and, consanguinity could be one of the causative factors in its development. The purpose of this study was, to determine the prevalence of parental consanguinity in CTEV and other factors like associated, congenital anomalies, maternal and fetal factors and also the severity of CTEV in these patients. The above factors were studied in 54 patients of less than 1 month of age with parental, consanguinity and 91 feet were evaluated for its severity using Dimeglio classification at the time of presentation. Out of 174 children presented to our department with CTEV, 54 (31%) children were born out, of consanguineous marriage. Thirty seven (68.5%) patients had bilateral CTEV. Twenty five (46.3%), patients had associated congenital anomalies and myelomeningocele being the commonest anomaly, associated. Out of 91 feet 61 (67%) were of grade 4 severity. High grade of severity observed in both idiopathic and non idiopathic CTEV suggests the, probable role of consanguinity as an etiological factor in the development of CTEV especially in our, part of the world.

    Congenital unilateral hydrocephalus is extremely uncommon with 18 cases previously reported in the English literature. Two additional newborns with unilateral hydrocephalus are presented. The second baby also presented a mega cisterna magna. This unusual association between Dandy-Walker variant and unilateral hydrocephalus has not been previously reported. Following ventriculo-peritoneal shunt, the babies had a normal cognitive neurodevelopment. The role of cranial computed tomography (CT) in diagnosis and follow-up is emphasized

    2016-10-01

    Full Text Available Congenital tremor type A‐II in piglets has been regarded as a transmissible disease since the 1970s, possibly caused by a very recently‐described virus: atypical porcine pestivirus (APPV. Here, we describe several strains of APPV in piglets with clinical signs of congenital tremor (10 of 10 farms tested. Piglets on a farm with no history of congenital tremor were PCR‐negative for the virus. To demonstrate a causal relationship between APPV and disease, three gilts were inoculated via intramuscular injection at day 32 of pregnancy. In two of the three litters, vertical transmission of the virus occurred. Clinical signs of congenital tremor were observed in APPV‐infected newborns, yet also two asymptomatic carriers were among the offspring. Piglets of one litter were PCR‐negative for the virus, and these piglets were all without congenital tremors. Long‐term follow up of farm piglets born with congenital tremors showed that the initially high viremia in serum declines at five months of age, but shedding of the virus in feces continues, which explains why the virus remains present at affected farms and causes new outbreaks. We conclude that trans‐placental transmission of APPV and subsequent infection of the fetuses is a very likely cause of congenital tremor type A‐II in piglets.

    To analyze the links between NFATC1 gene polymorphism and congenital heart disease in children. In the present study, we selected 85 children patients with congenital heart disease who were hospitalized from February 2013 to February 2015 as research subjects (observation group), and 92 healthy subjects as control group. Restriction fragment length polymorphism (RFLP) was used for analysis of NFATC1 gene in samples from each group. The distribution of NFATC1 genotype and allele between the observation group (children with congenital heart disease) and the control group showed no significant difference (p >0.05), but AA, GG genotypes, and allele frequency between pathological samples of children with congenital heart disease and the control group displayed significant difference (p congenital heart disease in observation group also showed a difference, i.e., homozygote (AA, GG) ratio in children with severe congenital heart disease is relatively high. There is a correlation between NFATC1 genes and the incidence of congenital heart disease in children, and a correlation between different genotypes and allele frequency and the incidence of the disease.

We investigated if exercise is safe and beneficial in patients with CM.Patients exercised on a stationary bike for 30 minutes, three times weekly, for 10 weeks at 70% of their maximal oxygen uptake (VO2max. Creatine kinase (CK was monitored as a marker of muscle damage. VO2max, functional tests, and questionnaires evaluated efficacy.Sixteen patients with CM were included in a controlled study. VO2max increased by 14% (range, 6-25%; 95% CI 7-20; p < 0.001 in the seven patients who completed training, and tended to decrease in a non-intervention group (n = 7; change -3.5%; range, -11-3%, p = 0.083. CK levels were normal and remained stable during training. Baseline Fatigue Severity Scale scores were high, 4.9 (SE 1.9, and tended to decrease (to 4.4 (SE 1.7; p = 0.08 with training. Nine patients dropped out of the training program. Fatigue was the major single reason.Ten weeks of endurance training is safe and improves fitness in patients with congenital myopathies. The training did not cause sarcomeric injury, even though sarcomeric function is affected by the genetic abnormalities in most patients with CM. Severe fatigue, which characterizes patients with CM, is a limiting factor for initiating training in CM, but tends to improve in those who train.The Regional Committee on Health Research Ethics of the Capital Region of Denmark H-2-2013-066 and ClinicalTrials.gov H2-2013-066.

    Full Text Available To obtain the basic data of congenital uronephropathy pattern and the affecting factors in children, we conducted a cross-sectional study at the Department of Child Health Cipto Mangunkusumo (CM Hospital Jakarta from 1995 to 1999 and 9 teaching hospitals throughout Indonesia. During the study period 134 patients were obtained, 116 patients from the CM Hospital and 18 patients from other teaching hospitals. Most patients (48.8% were below 1 year of age; male were affected more than female (2.4:1. The disorder was classified into two groups, i.e., congenital nephropathy and uropathy. There were 10 children with nephropathy, i.e., 4 with unilateral renal hypoplasia, 3 with polycystic kidney, and 3 with renal agenesis. In the uropathy group, 43 were with hypospadia, 22 with primary reflux vesicoureter, 18 with neurogenic bladder, and 17 with ureteropelvic junction obstruction. The complications found were urinary tract infection (71.2%, chronic renal failure (15.7%, hypertension (3.7%, and acute renal failure (1.5%. Consanguinity, familial disorders, maternal diseases, x-ray exposure and abortion efforts were found in a small proportion of patients. History of drug or herbs use in the first trimester of pregnancy was found in a large proportion of patients, mostly took analgesics (especially acetaminophen. In conclusion, uropathy disorders were much more common than congenital nephropathy. The most common complication was urinary tract infection, followed by chronic renal failure, hypertension, and acute renal failure.

    Improvements in the treatment of children with congenital heart disease have led to most of these patients reaching adulthood. Despite the increase in lifespan, very little is known about their quality of life - in particular, their ability to obtain a mortgage or consumer loan. To investigate the outcome of mortgage and loan applications made by adults with differential severities of congenital heart disease. Four hundred and seventy-six patients were invited to participate in a questionnaire-based interview by phone. Of these patients, one hundred and forty-two responded. Respondents were classified into three categories ('significant', 'complex' and 'mild') based on congenital heart disease severity according to the Bethesda conference. Ninety patients (64%) had applied for loans; 17 (16.5%) did not report their heart disease to the insurance company, 13 were refused insurance and 39 were asked to pay surplus fees. The imposed fees concerned patients classified in the 'significant' and 'complex' groups (Ploan had no influence on loan application outcomes. Adults with congenital heart disease are considerably more likely to have difficulty obtaining a mortgage or loan, independent of their congenital heart disease severity. Moreover, despite an increased obtainment of a loan in patients classified as 'mild', the refusal rates were identical for patients classified as having 'significant' or 'complex' congenital heart disease, although their prognosis is different.

  9. The ethics of abortions for fetuses with congenital abnormalities.

    Science.gov (United States)

    Jotkowitz, Alan; Zivotofsky, Ari Z

    2010-10-01

    Abortion remains a highly contentious moral issue, with the debate usually framed as a battle between the fetus's right to life and the woman's right to choose. Often overlooked in this debate is the impact of the concurrent legalization of abortion and the development of new prenatal screening tests on the birth prevalence of many inherited diseases. Most proponents of abortion support abortion for fetuses with severe congenital diseases, but there has unfortunately been, in our opinion, too little debate over the moral appropriateness of abortion for much less severe congenital conditions such as Down's syndrome, deafness, and dwarfism. Due to scientific advances, we are looking at a future in which prenatal diagnosis will be safer and more accurate, raising the specter, and the concomitant ethical concerns, of wholesale abortions. Herein, we present a reframing of the abortion debate that better encompasses these conditions and offers a more nuanced position. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Adult congenital cardiopathy is a clinical entity difficult to treat and diagnose. Since 1982 endovascular therapy changed its approach radically (1) and in the last years the design of new appliances and better balloon catheters facilitated the implementation of therapy to a greater number of patients (2). It is the election treatment for entities such as pulmonary valve stenosis (3), atrial septal defect (4) and persistent ductus arteriosus. We present the case of complex adult congenital cardiopathy that consisted of wide atrial septal defect,pulmonary valve stenosis with severe repercussion on the right ventricle, persistent PDA with severe calcification and pulmonary arterial hypertension and systemic essential arterial hypertension that were successfully treated through interventionist endovascular therapy in the Hospital Militar Central, in Bogota.

    2014-01-01

    Full Text Available Berardinelli-Seip congenital lipodystrophy (BSCL is a very rare autosomal recessive disorder characterized by various dermatological and systemic manifestations such as lipoatrophy, hypertriglyceridemia, hepatomegaly, acanthosis nigricans, and acromegaloid features. BSCL type 2 is more common and severe, with onset in the neonatal period or in early infancy. The locus for BSCL2 has been identified on chromosome 11q13. Early recognition and differentiation from other congenital generalized lipodystrophies help in the initiation of appropriate preventive and therapeutic measures such as lifestyle modification and pharmacotherapy that helps postpone the onset of metabolic syndrome. We report BSCL type 2 in two siblings with several cutaneous manifestations like acanthosis nigricans, hypertrichosis, prominent subcutaneous veins, and increased lanugo hair.

    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.

    Dapp, Michael J.; Patterson, Steven E.; Mansky, Louis M.

    2012-01-01

    The concept of eliminating HIV-1 infectivity by elevating the viral mutation rate was first proposed over a decade ago, even though the general concept had been conceived earlier for RNA viruses. Lethal mutagenesis was originally viewed as a novel chemotherapeutic approach for treating HIV-1 infection in which use of a viral mutagen would over multiple rounds of replication lead to the lethal accumulation of mutations, rendering the virus population non infectious – known as the slow mutation accumulation model. There have been limitations in obtaining good efficacy data with drug leads, leaving some doubt into clinical translation. More recent studies of the APOBEC3 proteins as well as new progress in the use of nucleoside analogs for inducing lethal mutagenesis have helped to refocus attention on rapid induction of HIV-1 lethal mutagenesis in a single or limited number of replication cycles leading to a rapid mutation accumulation model.

    In human genetics and orthopedics quite different answers have been given to the question of hereditary transmission and frequency of hip dysplasia in families of children with congenital hip dislocation. We therefore have made roentgenometric measurements of 110 parents of children with congenital hip dislocation. In 25% we found abnormal flat acetabulae, whereas 12% had pathologic deep hips.

    Perinatal-lethal Gaucher disease is very rare and is considered a variant of type 2 Gaucher disease that occurs in the neonatal period. The most distinct features of perinatal-lethal Gaucher disease are non-immune hydrops fetalis. Less common signs of the disease are hepatosplenomegaly, ichthyosis and arthrogryposis. We report a case of Gaucher's disease (type 2) diagnosed in a newborn who presented with Hydrops Fetalis.

    Full Text Available The results of following up infants with intrauterine infections and malformations were retrospectively analyzed. Infants with malformations were diagnosed as having congenital cytomegalovirus infection and congenital toxoplasmosis in 127 and 69 cases, respectively. The aim of the study was to characterize malformations in infants with congenital cytomegalovirus and congenital Toxoplasma infections. The infants with malformations in congenital cytomegalovirus infection were found to have higher mortality rates (61,4% than those with congenital toxoplasmosis (34,8%. Postmortem analysis indicated that there was a predominance of embryopathies in infants with congenital cytomegalovirus infection and that of fetopathies in those with congenital toxoplasmosis. The dead infants with congenital cytomegalovirus infection had more commonly developed visceral defects, including heart diseases, pneumopathies, gastrointestinal and genitourinary abnormalities; fetopathies of the central nervous system and eye were prevalent in congenital toxoplasmosis. The surviving children with congenital toxoplasmosis were more frequently observed to have disabling CNS and ocular sequels as obstructive hydrocephalus, infantile cerebral palsy, complete or partial blindness, and cerebrasthenic disorders than those with congenital cytomegalovirus infection. 

  8. A screen for F1 hybrid male rescue reveals no major-effect hybrid lethality loci in the Drosophila melanogaster autosomal genome.

    Hybrid sons between Drosophila melanogaster females and D. simulans males die as 3rd instar larvae. Two genes, D. melanogaster Hybrid male rescue (Hmr) on the X chromosome, and D. simulans Lethal hybrid rescue (Lhr) on chromosome II, interact to cause this lethality. Loss-of-function mutations in either gene suppress lethality, but several pieces of evidence suggest that additional factors are required for hybrid lethality. Here we screen the D. melanogaster autosomal genome by using the Bloomington Stock Center Deficiency kit to search for additional regions that can rescue hybrid male lethality. Our screen is designed to identify putative hybrid incompatibility (HI) genes similar to Hmr and Lhr which, when removed, are dominant suppressors of lethality. After screening 89% of the autosomal genome, we found no regions that rescue males to the adult stage. We did, however, identify several regions that rescue up to 13% of males to the pharate adult stage. This weak rescue suggests the presence of multiple minor-effect HI loci, but we were unable to map these loci to high resolution, presumably because weak rescue can be masked by genetic background effects. We attempted to test one candidate, the dosage compensation gene male specific lethal-3 (msl-3), by using RNA interference with short hairpin microRNA constructs targeted specifically against D. simulans msl-3 but failed to achieve knockdown, in part due to off-target effects. We conclude that the D. melanogaster autosomal genome likely does not contain additional major-effect HI loci. We also show that Hmr is insufficient to fully account for the lethality associated with the D. melanogaster X chromosome, suggesting that additional X-linked genes contribute to hybrid lethality.

  10. Murine model for congenital CMV infection and hearing impairment

    2011-02-01

    Full Text Available Abstract Background Congenital cytomegalovirus (CMV infection is the leading cause of sensorineural hearing loss (SNHL, and SNHL is the most frequent sequela of congenital CMV infection. But the pathogenic mechanism remains unknown, and there is no ideal CMV intrauterine infection animal model to study the mechanisms by which SNHL develops. Methods We established the congenital murine cytomegalovirus (MCMV infection model by directly injecting the virus into the placenta on day 12.5 of gestation. Then, we observed the development and the MCMV congenital infection rate of the fetuses on the day they were born. Furthermore, we detected the auditory functions, the conditions of the MCMV infection, and the histological change of the inner ears of 28-day-old and 70-day-old offspring. Results Both the fetal loss rate and the teratism rate of offspring whose placentas were inoculated with MCMV increased, and their body length, head circumference, and weight decreased. The hearing level of offspring both decreased at both 28- and 70-days post birth; the 70-day-old mice developed lower hearing levels than did the 28-day old mice. No significant inflammatory changes in the cochleae of the mice were observed. MCMV DNA signals were mainly detected in the spiral ganglion neurons and the endolymph area, but not in the perilymph area. The number of neurons decreased, and their ultrastructures changed. Moreover, with age, the number of neurons dramatically decreased, and the ultrastructural lesions of neurons became much more severe. Conclusions The results suggest that the direct injection of MCMV into the placenta may efficiently cause fetal infection and disturb the intrauterine development of the fetus, and placental inoculation itself has no obvious adverse effects on offspring. The reduction in the number of spiral ganglion neurons and the ultrastructural lesions of the neurons may be the major cause of congenital CMV infection-induced progressive SNHL.

  11. Test of the acute lethal toxicity of pollutants to marine fish and invertebrates

    International Nuclear Information System (INIS)

    1989-01-01

    This reference method describes the measurement of the acute lethal toxicity of pollutants to marine animals (fish and invertebrates) by a static (non-continuous flow) method. Procedures are given for the determination of the toxicity curve (survival time-concentration relationship) and for the estimation of median lethal concentrations (LC50). The method is suitable for use with fish and macro-invertebrate species. It is not suitable for planktonic organisms nor for determining the toxicity of oil, oil dispersants or other petroleum products. Those methods are described in Reference Methods Nos. 44 and 45, respectively. The test animals are exposed, in groups of approximately ten, to each of several concentrations of the pollutant. The animals are observed, at intervals, for several days, the test solutions being renewed regularly. A record is maintained of the survival times of individual animals exposed to each concentration of pollutant. The medial survival time of each group of animals is determined from a graphical plot of the raw data after a log-probability transformation. Median survival times and their confidence limits are plotted against concentrations of test substance to give a toxicity curve. Additionally, the same experimental data can be used to estimate the median lethal concentration (LC50) of the test substance to the animals after different periods of exposure. 3 refs, 5 figs, 3 tabs

    Congenital Zika virus infection can cause microcephaly and severe brain abnormalities (1). Congenital Zika syndrome comprises a spectrum of clinical features (2); however, as is the case with most newly recognized teratogens, the earliest documented clinical presentation is expected to be the most severe. Initial descriptions of the effects of in utero Zika virus infection centered prominently on the finding of congenital microcephaly (3). To assess the possibility of clinical presentations that do not include congenital microcephaly, a retrospective assessment of 13 infants from the Brazilian states of Pernambuco and Ceará with normal head size at birth and laboratory evidence of congenital Zika virus infection was conducted. All infants had brain abnormalities on neuroimaging consistent with congenital Zika syndrome, including decreased brain volume, ventriculomegaly, subcortical calcifications, and cortical malformations. The earliest evaluation occurred on the second day of life. Among all infants, head growth was documented to have decelerated as early as 5 months of age, and 11 infants had microcephaly. These findings provide evidence that among infants with prenatal exposure to Zika virus, the absence of microcephaly at birth does not exclude congenital Zika virus infection or the presence of Zika-related brain and other abnormalities. These findings support the recommendation for comprehensive medical and developmental follow-up of infants exposed to Zika virus prenatally. Early neuroimaging might identify brain abnormalities related to congenital Zika infection even among infants with a normal head circumference (4).

    Establishment of small animal models of Ebola virus (EBOV) infection is important both for the study of genetic determinants involved in the complex pathology of EBOV disease and for the preliminary screening of antivirals, production of therapeutic heterologic immunoglobulins, and experimental vaccine development. Since the wild-type EBOV is avirulent in rodents, the adaptation series of passages in these animals are required for the virulence/lethality to emerge in these models. Here, we provide an overview of our several adaptation series in guinea pigs, which resulted in the establishment of guinea pig-adapted EBOV (GPA-EBOV) variants different in their characteristics, while uniformly lethal for the infected animals, and compare the virologic, genetic, pathomorphologic, and immunologic findings with those obtained in the adaptation experiments of the other research groups.

    : Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death. This bleeding feature can also be observed in grey platelet syndrome, though less frequently than in Glanzmann's thrombasthenia. In hemophilia, intracerebral hemorrhage is affected by various risk factors one of which is the severity of the disease. The precise prevalence of ICH in these patients is not clear but an estimated incidence of 3.5-4% among newborns with hemophilia is largely ascertained. Although ICH is a rare phenomenon in CBDs, it can be experienced by every patient with severe hemophilia A and B, FXIII deficiency (FXIIID), FVIID, FXD, FVD, FIID, and afibrinogenemia. Upon observing the general signs and symptoms of ICH such as vomiting, seizure, unconsciousness, and headache, appropriate replacement therapies and cranial ultrasound scans must be done to decrease ICH-related morbidity and mortality.

The main complaint was edema starting 3 weeks before admission. Physical examination showed body weight for age (BW/A 14.3%, body weight for body length (BW/BL 66.0% and body length for age (BL/A 49.1%. On admission she looked severely ill, apathetic, with hypothermia and hypotonia. Almost all signs and symptoms of kwashiorkor and congenital hypothyroidism were found accompanied bronchopneumonia and dermatologic problems. Laboratory findings showed severe anemia, leukocytosis, hypoproteinemia, hyponatremia, hypokalemia, elevated thyroid stimulating hormone and low level of Thyroxine-4. Bone age equaled to a newborn baby bone age. There was no thyroid tissue on thyroid ultrasound examination. The patient was treated for severe protein energy malnutrition and ThyraxR. Problems of kwashiorkor could been solved well but not with the congenital hypothyroidism. She was discharged from hospital after 2 months treatment and till now at 14th year of age with her developmental milestones equals to that of 8 month old baby.

  19. Presence of virus neutralizing antibodies in cerebral spinal fluid correlates with non-lethal rabies in dogs.

    Directory of Open Access Journals (Sweden)

    Clement W Gnanadurai

    Full Text Available Rabies is traditionally considered a uniformly fatal disease after onset of clinical manifestations. However, increasing evidence indicates that non-lethal infection as well as recovery from flaccid paralysis and encephalitis occurs in laboratory animals as well as humans.Non-lethal rabies infection in dogs experimentally infected with wild type dog rabies virus (RABV, wt DRV-Mexico correlates with the presence of high level of virus neutralizing antibodies (VNA in the cerebral spinal fluid (CSF and mild immune cell accumulation in the central nervous system (CNS. By contrast, dogs that succumbed to rabies showed only little or no VNA in the serum or in the CSF and severe inflammation in the CNS. Dogs vaccinated with a rabies vaccine showed no clinical signs of rabies and survived challenge with a lethal dose of wild-type DRV. VNA was detected in the serum, but not in the CSF of immunized dogs. Thus the presence of VNA is critical for inhibiting virus spread within the CNS and eventually clearing the virus from the CNS.Non-lethal infection with wt RABV correlates with the presence of VNA in the CNS. Therefore production of VNA within the CNS or invasion of VNA from the periphery into the CNS via compromised blood-brain barrier is important for clearing the virus infection from CNS, thereby preventing an otherwise lethal rabies virus infection.

    Full Text Available Background: Congenital hypothyroidism (CH is a prevalent disorder, which is associated with several other congenital anomalies, especially cardiac diseases. The present study aimed to determine the prevalence of congenital heart disease (CHD in the neonates with CH.Methods: This cross-sectional study was conducted on two groups of 79 subjects to compare the type and frequency of congenital cardiac anomalies between the neonates with the confirmed diagnosis of CH (TSH≥10 mlU/ml and healthy infants. The study was performed in Kowsar Clinic affiliated to Arak University of Medical Sciences, Iran. Level of thyroid-stimulating hormone (TSH was measured within days 3-7 of birth using the samples collected from the soles of the neonates. In addition, all the subjects were evaluated for the presence of CHD using echocardiography before day 30 of life.Results: In total, 79 neonates were enrolled in the study. The case group consisted of 34 females (43.04% and 45 males (53.96%, and the control group consisted of 43 females (54.43% and 36 males (45.57%. The groups were matched in terms of age and gender. Cardiac involvement was only detected in the case group (CH infants with the prevalence of 22.7%. Among the non-cyanotic malformations observed in the case group, one infant had ventricular septal defect (1.3%, eight infants had atrial septal defect (10.1%, three infants had patent ductus arteriosus (3.8%, three neonates had endocardial cushion defect (3.8%, two neonates had pulmonary stenosis (2.5%, and one infant had dilated cardiomyopathy (1.3%. Moreover, six neonates were diagnosed with Down syndrome. All the infants with endocardial cushion defect (n=3 had Down syndrome, and no significant association was observed between TSH and thyroxine (T4 in the presence of CHD.Conclusion: According to the results, the high prevalence of cardiac malformations in the neonates with CH necessitated cardiac examinations using echocardiography.

  4. Can Telescopes Help Leo Satellites Dodge Most Lethal Impacts?

    GUDIEL, ANDREA; Carroll, Joseph; Rowe, David

    2018-01-01

    Authors: Joseph Carroll and David RoweABSTRACT LEO objects are tracked by radar because it works day and night, in all weather. This fits military interest in potentially hostile objects. There is less interest in objects too small to be credible active threats. But accidental hypervelocity impact by even 5-10 mm objects can disable most LEO satellites. Such “cm-class” objects greatly outnumber objects of military interest, and will cause most accidental impact losses.Under good viewing conditions, a sunlit 5mm sphere with 0.15 albedo at 800 km altitude is a 19th magnitude object. A ground-based 0.5m telescope tracking it against a 20 mag/arcsec2 sky can see it in seconds, and provide 1 million such objects in LEO, nearly all debris fragments, mostly cm-class and at 600-1200 km altitude.Maintaining a ~million-item catalog requires a world-wide network of several dozen telescope sites with several telescopes at each site. Each telescope needs a mount capable of ~1,000,000 fast slews/year without wearing out.The paper discusses recent advances that make such a service far more feasible:1. Automated tasking and remote control of distributed telescope networks,2. Direct-drive mounts that can make millions of fast slews without wearing out,3. Telescope optics with low focal curvature that are in focus across large imagers,4. CMOS imagers with 95% peak QE and 1.5e- noise at 2E8 pix/sec readout rates,5. Methods for uncued detection of most lethal LEO debris (eg., >5 mm at 800 km),6. Initial orbit determination using 3 alt-az fixes made during the discovery pass,7. High-speed photometry to infer debris spin axis, to predict drag area changes,8. Better conjunction predictions using explicit modeling of drag area variations.

    Two cases of adrenomyeloneuropathy (AMN) in a family and the results of their MRI study are reported. Case 1, a 24-year-old male proband, was admitted to our hospital because of gait disturbance for three years. Bilateral cataracts were pointed out at birth, which required left side lenticotomy at age four. Neurological examinations on admission revealed a marked spastic paraparesis with pathological reflexes and a mild hypesthesia in the distal part of the left leg. No abnormal findings were detected in X-ray studies on the spine and spinal cord, electromyography and nerve conduction test. Serum very long chain fatty acids (VLCFAs) levels were apparently elevated, and the serum cortisol response to ACTH was low. Case 2, a 53-year-old woman, is the mother of Case 1 having a complaint of gait disturbance since age 51. She presented a mild spastic paraparesis with localized hypesthesia in the distal part of the both legs. She also had bilateral congenital cataracts. Her serum VLCFAs analysis indicated the intermediate levels between that of AMN and the normal control. Adrenal functions were normal. Cranial MRI (TR 2,000 msec/TE 80 msec) study disclosed high signal intensity areas in bilateral internal capsules in Case 1. These findings, suggesting the pathological change of dysmyelination, seemed to be well compatible with the clinical pictures. With these clinical findings and the laboratory data, these two cases were diagnosed as AMN. In addition, association of congenital cataract with AMN in both cases was characteristic in this family, which hasn't been reported in the literature. On regarding the genetic background of these two disorders, AMN and congenital cataract, it was speculated that each gene could be closely located on the same or very adjacent locus, possibly on Xq.

With an incidence of 1:5000 to 1:8000 births, it is twice as prevalent in females as it is in males. Surgical procedures aim to provide adequate functional choanal patency and a low rate of restenosis, avoid harm to any structure in development, enable shorter surgery and hospitalization times, and minimize morbidity and mortality. To evaluate the effectiveness and safety of the available surgical techniques for the treatment of congenital choanal atresia in patients with unilateral and bilateral atresia. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ISRCTN and additional sources for published and unpublished trials. The date of the search was 31 January 2011. We planned to include parallel randomized or quasi-randomized controlled trials testing surgical approaches for the treatment of congenital atresia (irrespective of gender and age) that evaluated normal/adequate respiratory function (self reported or preserved nasal airway) and restenosis as the main primary outcomes. We did not consider reoperation and non-congenital atresia (e.g. traumatic, iatrogenic atresias) for inclusion. Three review authors independently assessed the titles and abstracts of the identified articles to determine potential relevance. For dichotomous and continuous variables, we planned to calculate risk ratios (relative risks; RR) and mean differences (MD) with 95% confidence intervals (CI), respectively. We planned to use the random-effects model since we were expecting substantial clinical and methodological heterogeneity. No randomized controlled trials were identified. From the 120 reports retrieved using our search strategy, 46 primary studies had the

    Recent studies have demonstrated that screening and treatment for toxoplasmosis during gestation result in a decrease of vertical transmission and clinical sequelae. Early treatment was associated with improved outcomes. Thus, laboratory methods should aim for early identification of infants with congenital toxoplasmosis (CT). Diagnostic approaches should include, at least, detection of Toxoplasma IgG, IgM, and IgA and a comprehensive review of maternal history, including the gestational age at which the mother was infected and treatment. Here, we review laboratory methods for the diagnosis of CT, with emphasis on serological tools. A diagnostic algorithm that takes into account maternal history is presented. PMID:27147724

    Objective: Although the ocular motility examination has been traditionally used in the diagnosis of complex strabismus resulting from cranial nerve (CN) and extraocular muscles (EOM) abnormalities, magnetic resonance imaging (MRI) now permits the direct imaging of lesions in CNs and EOMs. Methods: Twenty-six patients with complex strabismus underwent MRI examination on 1.5 T MR unit (Twinspeed, GE). Nerves to EOMs were imaged with T 1 weighted in orbits in all patients using phase array surface coils. Results: Patients with Duane syndrome (15 cases, 19 eyes) all exhibited absence or hypoplasia of abducens nerve (CN6), always with mild hypoplasia and apparent misdirection of oculomotor nerve (CN3) to the lateral rectus muscle in the orbit, and there were no hypoplasia of EOMs. Patients with congenital fibrosis of EOMs (9 cases, 16 eyes) exhibited severe hypoplasia of CN3 and CN6, and EOMs appeared hypoptasia to a different degree, particularly severe for the superior rectus and levated palpted muscles. Multiple nerves displayed aplasia in patients with Mobius syndrome (1 ease, 2 eyes) and there was abnormal branch from CN3 to lateral rectus. The tendons of bilateral superior oblique muscles were thin in the patients with Brown syndrome (1 case, 2 eyes). Conclusion: MRI can directly demonstrate absence or hypoplasia of CNs and corresponding EOM abnormalities in congenital complex strabismus, which suggests that the mechanism of congenital complex strabismus is perhaps abnormal innervation or displasia of the ocular motor nerves.
