    From 1975 to 2004 a total of 38 children handicapped by congenital multiple arthrogryposis were cared for. The congenital joint contractures demand a major effort in terms of surgical reconstruction. In the case of distal arthrogryposis the chances that patients will be able to walk without help are good, while those with amyoplasia are likely to be dependent on mobility aids throughout their lives. The ultimate goal of treatment for patients is to develop into self-confident adults who can cope with life despite their handicaps. The hip in arthrogryposis shows variable forms of pathology, ranging from the almost normal hip to hip contractures with dislocation. Its treatment has some limited advantages, but hardly improves mobility. The knee contractures are actively treated to allow patients to sit, stand and walk better. The club foot and the rocker-bottom foot need sophisticated conservative and operative treatments. If conservative manipulation of bilateral extension contractures of the elbow fails operative treatment is carried out on the dominant side. For shoulder, hand and finger contractures conservative manipulation brings about little improvement, and surgical approaches help hardly at all. PMID:17323063

    Full Text Available Arthrogryposis is a congenital disorder characterized by multiple joint contractures found throughout the body at birth. We present the case of a 3.5 year-old girl with multiple congenital defects: arthrogryposis involving bilateral hip, knee and ankle joints, together with sacral agenesis and with lumbar dysmorphism, anorectal agenesis, hydronephrosis of the left kidney as the result from reflux, right kidney hypoplasia, renal fusion and heart anomalies: tetralogy of Fallot. Immediately after birth, in several steps, colostomy, left ureterocystoneostomy and suprapubic cystostomy were performed. Later in infancy corrective surgery for the heart defect was required. At the age of 2 years, surgery for the equinovarus deformities and for left genu flexum was performed. Medical rehabilitation tries to maximize independent function. The main goals were increasing the muscle tonus of upper-limbs, increase the rate of motion of the joints, establishment of stability for ambulation, learning different schemes of movement according to her needs, obtaining of a functional independency. The therapies were successful, after 10 weeks an improvement of the moving capacity and of the transfer in orthostatism with minimal external assistance, with the obvious increasing of the patient's satisfaction, were noticed.

    Full Text Available A 5-month-old male infant presented with weak cry, decreased body movements, tightness of whole body since birth, and one episode of generalized seizure on day 4 of life. He was born at term by elective caesarian section performed for breech presentation. The child had failure to thrive, contractures at elbow and knee joints, hypertonia, microcephaly, small mouth, retrognathia, and camptodactyly. There was global developmental delay. Abdominal examination revealed umbilical and bilateral inguinal hernia. Visual evoked response and brainstem evoked response audiometry were abnormal. Nerve conduction velocity was normal. Magnetic resonance imaging of brain revealed paucity of white matter in bilateral cerebral hemispheres with cerebellar and brain stem atrophy. The differential diagnoses considered in the index patient were distal arthrogryposis (DA syndrome, cerebroculofacioskeletal syndrome, and Pena Shokier syndrome. The index patient most likely represents a variant of DA: Sheldon Hall syndrome.

    Arthrogryposis is a rare condition characterised by multiple congenital joint contractures. We present a case of a 10-year-old child with arthrogryposis and snoring. Polysomnography revealed significant obstructive sleep apnoea and hypoventilation that improved but did not completely resolve with adenotonsillectomy. With continuous positive airway pressure (CPAP) therapy, there was full resolution of all sleep disordered breathing. Initially, the patient admitted to difficulty tolerating nasal CPAP at home. However, she steadily improved adherence to therapy and admitted that with nasal CPAP use for the whole night, she felt more energised during the daytime. PMID:24907203

    Arthrogryposis by definition has multiple congenital contractures. All types of arthrogryposis have decreased in utero fetal movement. Because so many things are involved in normal fetal movement, there are many causes and processes that can go awry. In this era of molecular genetics, we have tried to place the known mutated genes seen in genetic forms of arthrogryposis into biological processes or cellular functions as defined by gene ontology. We hope this leads to better identification of all interacting pathways and processes involved in the development of fetal movement in order to improve diagnosis of the genetic forms of arthrogryposis, to lead to the development of molecular therapies, and to help better define the natural history of various types of arthrogryposis.

    Full Text Available ABSTRACT OBJECTIVE: Arthrogryposis multiplex congenita is a relatively rare neuromuscular syndrome, with a prevalence of 1:3000-5000 newborns. In this study, the authors describe the clinical features of a group of 50 unrelated Mexican patients with arthrogryposis multiplex congenita. METHODS: Patients were diagnosed by physical and radiographic examination and the family history was evaluated. RESULTS: Of the 50 cases, nine presented other features (pectum excavatum, cleft palate, mental retardation, ulnar agenesis, etc.. Environmental factors, as well as prenatal and family history, were analyzed. The chromosomal anomalies and clinical entities associated with arthrogryposis multiplex congenita were reported. No chromosomal aberrations were present in the cases with mental retardation. Three unrelated familial cases with arthrogryposis multiplex congenita were observed in which autosomal recessive, autosomal dominant and X-linked inheritance patterns are possible. A literature review regarding arthrogryposis multiplex congenita was also conducted. CONCLUSIONS: It is important to establish patient-specific physical therapy and rehabilitation programs. A multidisciplinary approach is necessary, with medical, surgical, rehabilitation, social and psychological care, including genetic counseling.

    Objective To describe the clinical, radiological, and electromyographic features in a series of children with joint contractures (arthrogryposis) associated with congenital infection presumably caused by Zika virus. Design Retrospective case series study. Setting Association for Assistance of Disabled Children, Pernambuco state, Brazil. Participants Seven children with arthrogryposis and a diagnosis of congenital infection presumably caused by Zika virus during the Brazilian microcephaly epidemic. Main outcome measures Main clinical, radiological, and electromyographic findings, and likely correlation between clinical and primary neurological abnormalities. Results The brain images of all seven children were characteristic of congenital infection and arthrogryposis. Two children tested positive for IgM to Zika virus in the cerebrospinal fluid. Arthrogryposis was present in the arms and legs of six children (86%) and the legs of one child (14%). Hip radiographs showed bilateral dislocation in seven children, subluxation of the knee associated with genu valgus in three children (43%), which was bilateral in two (29%). All the children underwent high definition ultrasonography of the joints, and there was no evidence of abnormalities. Moderate signs of remodeling of the motor units and a reduced recruitment pattern were found on needle electromyography (monopolar). Five of the children underwent brain computed tomography (CT) and magnetic resonance imaging (MRI) and the remaining two CT only. All presented malformations of cortical development, calcifications predominantly in the cortex and subcortical white matter (especially in the junction between the cortex and white matter), reduction in brain volume, ventriculomegaly, and hypoplasia of the brainstem and cerebellum. MRI of the spine in four children showed apparent thinning of the cord and reduced ventral roots. Conclusions Congenital Zika syndrome should be added to the differential diagnosis of congenital

    Full Text Available Abstract Background The reported incidence of scoliosis in arthrogryposis varies from 30% to 67% and, in most cases, the curves progress rapidly and become stiff from early age. The authors report six cases of scoliosis in arthrogryposis to assess the role of surgical treatment. Methods Six cases (3 males, 3 females; mean age at surgery 13.2 years with arthrogryposis multiplex congenita associated with the characteristic amyoplasia were reviewed: they were operated on for scoliosis at the authors' Spine Surgery Department between 1987 and 2008. Surgery was performed using the Harrington-Luque instrumentation (2 cases, the Luque system (1, a hybrid segmental technique with hooks and screws (1 and spinal anchoring with pedicle screws (2. Results The patients were clinically and radiologically reviewed at a mean follow-up of 4.2 years, ± 2.7 (range, 1 to 9 years. Three minor postoperative complications were encountered; a long-term pulmonary complication was seen in one case after reintervention and was successfully resolved after 10 days. Surgery was successful in the other 5 cases, where solid arthrodesis was achieved and no significant curve progression was observed at follow-up. Conclusions The experience acquired with the present case series leads the authors to assert that prompt action should be taken when treating such aggressive forms of scoliosis. In case of mild spinal deformities in arthrogryposis, brace treatment should be attempted, the evolution of the curves being unpredictable; however, when the curve exceeds 40° and presents with marked hyperkyphosis, hyperlordosis or pelvic obliquity, surgery should not be delayed.

    Arthrogryposis multiplex congenital is a rare condition defined as contractures in multiple joints at birth due to disorders starting in fetal life. Its etiology is associated with many different conditions and in many instances remains unknown. The final common pathway to all of them is decreased fetal movement (fetal akinesia) due to an abnormal intrauterine environment. Causes of decreased fetal movements may be neuropathic abnormalities, abnormalities of connective tissue or muscle, intrauterine vascular compromise, maternal diseases, and space limitations within the uterus. When the cause of arthrogryposis is space limitations in uterus, the most common etiology is oligohydramnios. The same can result from intrauterine tumours as fibroids, although to our knowledge there are only two papers reporting cases of fetal deformities related to uterine leiomyomas. We describe a well-documented exceptional case of arthrogryposis associated with the presence of a large uterine fibroid. It could illustrate the importance of a careful and appropriate assessment of uterine fibroids before and in the course of a pregnancy considering that they can cause both serious maternal and fetal complications.

    Full Text Available Introduction: Arthrogryposis multiplex congenita is not a disease but a term describing multiple congenital contractures. Etiological factors include neurological and primary myogenic diseases. This rare syndrome is present at birth and is characterized by reduced mobility of many joints. The contractures involve two or more joints with ankylosis. The accompanying musculature is hypoplastic, but multiple pterygia are also present. Arthrogryposis multiplex congenita is a heterogeneous group of disorders with the incidence rate of 6.2/100000 liveborn infants. The true incidence cannot be established, because many cases result in spontaneous miscarriages or stillbirth. More than 90% of cases are associated with birth defects. The cause of this syndrome is unknown. Many forms are not hereditary, though there are hereditary forms as well. Case report. This paper presents a case with arthrogryposis multiplex congenita. The pregnancy was not controlled regularly. During the pregnancy, oligohydramnion was detected. Due to contractures, labor ended is cesarean section. The child was born in the 34th week of gestation. Flexion and extension joint contractures were observed. Active and passive mobility of the afflicted joints was reduced. There was a limited motor function in the shoulder, elbow and wrist joints with a slight internal rotation of the shoulder joint and lower arm joints during pronation. The hips were subluxated; the feet were in equinovarus position and the fingers in ulnar deviation with partial syndactyly of the 4th and 5th fingers on the left hand. The infant had abnormal dermatoglyphics. The neck was short, and the 2nd and 3rd cervical vertebrae were fused. There was also a slight left-sided thoracic scoliosis. Trismus was present due to the existing ankylosis of the temporomandibular joint. The karyotype was normal. The serum creatinine phosphokinase was slightly elevated. The electromyographic picture indicate non-specific signs of

  12. CT-scanning of skeletal muscle in arthrogryposis multiplex congenita

    International Nuclear Information System (INIS)

    CT-scanning of skeletal muscles was performed on 14 patients with arthrogryposis multiplex congenita (AMC), according to an eight-slice protocol. Adipose tissue replacement and atrophy of muscles was found in six patients with neurogenic or myopathic origin of AMC, associated with severe muscle weakness. In the remaining patients with other forms of AMC, in which muscle weakness was less marked or absent, muscular CT-scanning was normal. It is stated that muscular CT-scanning is not a routine investigation in a screening procedure of all cases of AMC. However, CT-scanning appears to be useful in cases of severe AMC with associated muscle weakness in detecting the neurogenic and myopathic forms. It also facilitates the selection of a suitable site for EMG and biopsy and may provide important information for orthopaedic management. (author)

    Arthrogryposis is a condition characterized by symmetric, nonprogressive joint contractures and weak or absent musculature that is present at birth. The amyoplasia form is the most common, and in this group, the elbow is frequently involved, typically in an extension contracture bilaterally. Active elbow flexion is weak or absent, but active extension is spared. This elbow dysfunction poses a significant disability for affected children. Sensation and cognitive development is normal in children with arthrogryposis, and as a group they demonstrate a remarkable degree of adaptability to their deformities. The goal of any treatment is to facilitate the child's functional independence. This article describes the surgical technique of transfer of the long head of the triceps into the proximal ulna to provide active elbow flexion in children with arthrogryposis. The goal of the procedure is to reliably achieve antigravity active flexion while preserving active extension. It has the advantages of technical simplicity and minimal donor site morbidity. By adding this procedure to the existing options for treating this challenging condition, a surgeon is better able to tailor intervention to an individual child's strength and available donor muscles.

    The membrane-bound metalloprotease endothelin-converting enzyme-like 1 (ECEL1) has been newly identified as a causal gene of a specific type of distal arthrogryposis (DA). In contrast to most causal genes of DA, ECEL1 is predominantly expressed in neuronal cells, suggesting a unique neurogenic pathogenesis in a subset of DA patients with ECEL1 mutation. The present study analyzed developmental motor innervation and neuromuscular junction formation in limbs of the rodent homologue damage-induced neuronal endopeptidase (DINE)-deficient mouse. Whole-mount immunostaining was performed in DINE-deficient limbs expressing motoneuron-specific GFP to visualize motor innervation throughout the limb. Although DINE-deficient motor nerves displayed normal trajectory patterns from the spinal cord to skeletal muscles, they indicated impaired axonal arborization in skeletal muscles in the forelimbs and hindlimbs. Systematic examination of motor innervation in over 10 different hindlimb muscles provided evidence that DINE gene disruption leads to insufficient arborization of motor nerves after arriving at the skeletal muscle. Interestingly, the axonal arborization defect in foot muscles appeared more severe than in other hindlimb muscles, which was partially consistent with the proximal-distal phenotypic discordance observed in DA patients. Additionally, the number of innervated neuromuscular junction was significantly reduced in the severely affected DINE-deficient muscle. Furthermore, we generated a DINE knock-in (KI) mouse model with a pathogenic mutation, which was recently identified in DA patients. Axonal arborization defects were clearly detected in motor nerves of the DINE KI limb, which was identical to the DINE-deficient limb. Given that the encoded sequences, as well as ECEL1 and DINE expression profiles, are highly conserved between mouse and human, abnormal arborization of motor axons and subsequent failure of NMJ formation could be a primary cause of DA with ECEL1

    Arthrogryposis multiplex congenita (AMC) is caused by heterogeneous pathologies leading to multiple antenatal joint contractures through fetal akinesia. Understanding the pathophysiology of this disorder is important for clinical care of the affected individuals and genetic counseling of the families. We thus aimed to establish the genetic basis of an AMC subtype that is associated with multiple dysmorphic features and intellectual disability (ID). We used haplotype analysis, next-generation sequencing, array comparative genomic hybridization, and chromosome breakpoint mapping to identify the pathogenic mutations in families and simplex cases. Suspected disease variants were verified by cosegregation analysis. We identified disease-causing mutations in the zinc-finger gene ZC4H2 in four families affected by X-linked AMC plus ID and one family affected by cerebral palsy. Several heterozygous females were also affected, but to a lesser degree. Furthermore, we found two ZC4H2 deletions and one rearrangement in two female and one male unrelated simplex cases, respectively. In mouse primary hippocampal neurons, transiently produced ZC4H2 localized to the postsynaptic compartment of excitatory synapses, and the altered protein influenced dendritic spine density. In zebrafish, antisense-morpholino-mediated zc4h2 knockdown caused abnormal swimming and impaired α-motoneuron development. All missense mutations identified herein failed to rescue the swimming defect of zebrafish morphants. We conclude that ZC4H2 point mutations, rearrangements, and small deletions cause a clinically variable broad-spectrum neurodevelopmental disorder of the central and peripheral nervous systems in both familial and simplex cases of both sexes. Our results highlight the importance of ZC4H2 for genetic testing of individuals presenting with ID plus muscle weakness and minor or major forms of AMC. PMID:23623388

    The Clubfoot painted by José de Ribera depicts a young beggar affected by a typical equinus clubfoot. He shows a contorted right hand and wrist. His left hand holds a begging note, suggesting some difficulty to speak. This condition may be caused by a cerebral palsy, consisting of a brain injury in the left hemisphere responsible for right hemiplegia and speech disturbance. Recently, it was suggested that the boy's condition is a consequence of arthrogryposis, perhaps amyoplasia or distal arthrogryposis type A1. Some clinical features may suggest the diagnosis of Sheldon-Hall syndrome. Considering all the signs represented on the painting, the diagnosis of hemiplegia due to cerebral palsy cannot be discarded. The present article is a novel analysis of the painting based on previously proposed diagnoses of the boy's condition, namely, hemiplegia and arthrogryposis. PMID:26414783

    A congenital skeletal deformity called crooked calf syndrome occurs in many of the beef cattle-producing areas of the western United States. This deformity is characterized by arthrogryposis, torticollis, scoliosis, and cleft palate. The condition is non-hereditary, and is due to the consumption of lupin by the dam. The most severe and characteristic deformities are produced between the 40th and 70th days of gestation. Experimental analyses were performed to ascertain the teratogenic effect of lupin plants, lupin and lead, and lead alone upon cattle.

    Myasthenia gravis in children can be generalized or ocular, and associated with antibodies to acetylcholine receptors or muscle-specific kinase, but it can be negative for those antibodies (seronegative). It needs to be distinguished from congenital myasthenic syndromes and other neuromuscular diseases. In the perinatal period, transient neonatal myasthenia and arthrogryposis multiplex congenita, due to maternal antibodies, need to be considered. Juvenile myasthenia is similar in presentation and treatment to that in adults. Here we present guidelines for recognition, diagnosis, and treatment. PMID:23622368

    Full Text Available Abstract Sheldon-Hall syndrome (SHS is a rare multiple congenital contracture syndrome characterized by contractures of the distal joints of the limbs, triangular face, downslanting palpebral fissures, small mouth, and high arched palate. Epidemiological data for the prevalence of SHS are not available, but less than 100 cases have been reported in the literature. Other common clinical features of SHS include prominent nasolabial folds, high arched palate, attached earlobes, mild cervical webbing, short stature, severe camptodactyly, ulnar deviation, and vertical talus and/or talipes equinovarus. Typically, the contractures are most severe at birth and non-progressive. SHS is inherited in an autosomal dominant pattern but about half the cases are sporadic. Mutations in either MYH3, TNNI2, or TNNT3 have been found in about 50% of cases. These genes encode proteins of the contractile apparatus of fast twitch skeletal muscle fibers. The diagnosis of SHS is based on clinical criteria. Mutation analysis is useful to distinguish SHS from arthrogryposis syndromes with similar features (e.g. distal arthrogryposis 1 and Freeman-Sheldon syndrome. Prenatal diagnosis by ultrasonography is feasible at 18–24 weeks of gestation. If the family history is positive and the mutation is known in the family, prenatal molecular genetic diagnosis is possible. There is no specific therapy for SHS. However, patients benefit from early intervention with occupational and physical therapy, serial casting, and/or surgery. Life expectancy and cognitive abilities are normal.

    Genotype-phenotype analysis of at least 25 individuals with interstitial 16p13.3 duplications defines a recognizable syndrome associated with duplication of a critical Rubinstein-Taybi region encompassing only the CREBBP gene. Nevertheless, variable or incompletely penetrant phenotype has been reported previously. We here report a case of a 5-year old boy with a recognizable phenotype of this syndrome, including intellectual disability, mild arthrogryposis, small and proximally implanted thumbs and characteristic facial features. In addition, growth delay, microcephaly and distinguishable structural brain MRI abnormalities were observed. A de novo 1.5 Mb interstitial duplication of 16p13.3 was detected by SNP-array and fluorescence in situ hybridization (FISH). Short tandem repeat polymorphism (STRP) analysis with marker D16S475 indicated that the duplication was formed before maternal meiosis II. Our findings highlight the variable clinical features and further expand the phenotypic spectrum correlated with this lately proposed syndrome. PMID:24035902

    A 37-yr-old Asian elephant (Elephas maximus) started parturition after 640 days of pregnancy but no fetal parts entered the birth canal. Despite veterinary intervention, the calf was not delivered. After 13 mo calving resumed and a full-term dead calf advanced into and lodged within the vagina. With standing xylazine tranquilization, the dam received a vagino-vestibulotomy to permit total fetotomy of the calf, which presented with bilateral carpal arthrogryposis. Severe infection of the caudal vaginal vestibulum complicated wound healing, and over the following year two corrective surgeries were performed, which resolved the fistula 3 mo after the second debridement. The elephant not only survived the procedures but also resumed normal estrous cycles, as demonstrated by blood progesterone concentration monitoring. PMID:23505713

    We compared the phenotypes, karyotypes, and molecular data for six cases of partial monosomy 21. Regions of chromosome 21, the deletion of which corresponds to particular features of monosomy 21, were thereby defined. Five such regions were identified for 21 features. Ten of the features could be assigned to the region flanked by genes APP and SOD1: six facial features, transverse palmar crease, arthrogryposis-like symptoms, hypertonia, and contribution to mental retardation. This region, covering the interface of bands 21q21-21q22.1, is 4.7-6.4 Mb long and contains the gene encoding the glutamate receptor subunit GluR5 (GRIK1). 82 refs., 5 figs., 1 tab.

    Cornelia de Lange Syndrome (CdLS) (also called Bushy Syndrome or Amsterdam dwarfism), is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth), upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    Congenital lumbar hernias are rare malformations caused by defects in the development of the posterior abdominal wall. A known association exists with lumbocostovertebral syndrome; however other associated anomalies, including one case with arthrogryposis, have been previously reported. We present an infant girl with bilateral congenital lumbar hernias, multiple joint contractures, decreased muscle bulk and symptoms of malignant hyperthermia. Molecular testing revealed an R4861C mutation in the ryanodine receptor 1 (RYR1) gene, known to be associated with central core disease. This is the first reported case of the co-occurrence of congenital lumbar hernias and central core disease. We hypothesize that ryanodine receptor 1 mutations may interrupt muscle differentiation and development. Further, this case suggests an expansion of the ryanodine receptor 1-related myopathy phenotype to include congenital lumbar hernias. PMID:26684984

  9. Complex Vertebral Malformation (CVM) in an Italian Holstein calf

    International Nuclear Information System (INIS)

    Complex Vertebral Malformation, a congenital and lethal genetic defect of Holstein breed, has been recently observed in different Countries all over the world. In this paper the AA describe the clinical and radiological aspects of CVM in a two day old female calf. The disease was characterized by low body weight, symmetrical arthrogryposis and partial rotation of all legs and scoliosis. Calf was alert and showed physiological appetite, but was not able to maintain the quadrupedal stance. Radiographs of the vertebral column showed multiple vertebral anomalies, including hemivertebrae, fused and misshapen vertebrae and ribs and scoliosis, that affected mainly the caudal, cervical and thoracic regions. At necropsy, besides the skeleton anomalies, complex malformation of the heart was observed, which included atrial and interventricular defects and patent ductus arteriosus. This is the first case of CVM completely documented and genetically tested in Italy

    Post-translational modifications are necessary for collagen precursor molecules (procollagens) to acquire final shape and function. However, the mechanism and contribution of collagen modifications that occur outside the endoplasmic reticulum and Golgi are not understood. We discovered that VIPAR, with its partner proteins, regulate sorting of lysyl hydroxylase 3 (LH3, also known as PLOD3) into newly identified post-Golgi collagen IV carriers and that VIPAR-dependent sorting is essential for modification of lysines in multiple collagen types. Identification of structural and functional collagen abnormalities in cells and tissues from patients and murine models of the autosomal recessive multisystem disorder Arthrogryposis, Renal dysfunction and Cholestasis syndrome caused by VIPAR and VPS33B deficiencies confirmed our findings. Thus, regulation of post-Golgi LH3 trafficking is essential for collagen homeostasis and for the development and function of multiple organs and tissues. PMID:27435297

    Freeman-Sheldon syndrome, or distal arthrogryposis type 2A (DA2A), is an autosomal-dominant condition caused by mutations in MYH3 and characterized by multiple congenital contractures of the face and limbs and normal cognitive development. We identified a subset of five individuals who had been putatively diagnosed with “DA2A with severe neurological abnormalities” and for whom congenital contractures of the limbs and face, hypotonia, and global developmental delay had resulted in early death in three cases; this is a unique condition that we now refer to as CLIFAHDD syndrome. Exome sequencing identified missense mutations in the sodium leak channel, non-selective (NALCN) in four families affected by CLIFAHDD syndrome. We used molecular-inversion probes to screen for NALCN in a cohort of 202 distal arthrogryposis (DA)-affected individuals as well as concurrent exome sequencing of six other DA-affected individuals, thus revealing NALCN mutations in ten additional families with “atypical” forms of DA. All 14 mutations were missense variants predicted to alter amino acid residues in or near the S5 and S6 pore-forming segments of NALCN, highlighting the functional importance of these segments. In vitro functional studies demonstrated that NALCN alterations nearly abolished the expression of wild-type NALCN, suggesting that alterations that cause CLIFAHDD syndrome have a dominant-negative effect. In contrast, homozygosity for mutations in other regions of NALCN has been reported in three families affected by an autosomal-recessive condition characterized mainly by hypotonia and severe intellectual disability. Accordingly, mutations in NALCN can cause either a recessive or dominant condition characterized by varied though overlapping phenotypic features, perhaps based on the type of mutation and affected protein domain(s).

    Full Text Available Abstract Background Schistosoma reflexum (SR is congenital syndrome briefly characterized by visceral eventration, severe dorsoflexion and ankylosis of the spine and arthrogryposis. A genetic etiology has been proposed, but conclusive evidence has not yet been provided. Methods Pedigree analysis was carried out in 29 cases of SR in Czech Holsteins and Holstein crosses. Genetic relationship was evaluated and inbreeding coefficients calculated. Pedigrees of 15 Czech Holsteins fathering non-SR affected calves were used for comparison. Results Twenty-one cases occurred in one pedigree founded by three sires while three SR calves occurred in another pedigree with a common grandfather. The sex ratio between affected males and females was 11:6. Affected calves shared common ancestors different from those shared by the unaffected calves. The inbreeding coefficient in the SR affected calves was not increased compared to unaffected calves. Conclusions The findings are consistent with SR being inherited autosomal recessively. Further studies are however needed to confirm this and therefore a breeding trial is recommended where a suspected heterozygous sire is mated to closely related females.

    Full Text Available Objective: The purpose of this study is to evaluate the results of Ponseti technique in the management of congenital Talipes Equino Varus (CTEV in neonatal age group.Methods: It is a prospective observational study, conducted during the period of July 2010 to December 2011 at the Department of Pediatric Surgery in a tertiary hospital. All the neonates with CTEV were treated with Ponseti casting technique. Neonates with other congenital deformities, arthrogryposis and myelomeningocele were excluded.Results: Total 58 CTEV feet of 38 neonates were treated. Twenty six were males and 12 were females. Thirty seven (63.8% feet were of rigid variety and 21(36.2 % feet were of non-rigid variety. Twenty patients had bilateral and 18 had unilateral involvement. Mean pre-treatment Pirani score of study group was 5.57. Mean number of plaster casts required per CTEV was 3.75 (range: 2-6. Thirty five rigid and 15 non-rigid (total 86.2% feet required percutaneous tenotomy. Out of 58 feet 56 (96.6% were managed successfully. Three (5.2% patients developed complications like skin excoriation and blister formation. Mean post-treatment Pirani score of the study group was: 0.36 ± 0.43.Conclusion: The Ponseti technique is an excellent, simple, effective, minimally invasive, and inexpensive procedure for the treatment CTEV deformity. Ideally it can be performed as a day case procedure without general anesthesia even in neonatal period.

    Full Text Available Abstract Background Spine deformity can be idiopathic (more than 80% of cases, neuromuscular, congenital or neurofibromatosis-related. However, there are many disorders that may also be involved. We present our experience treating patients with scoliosis or other spine deformities related to rare clinical entities. Methods A retrospective study of the records of a school-screening study in North-West Greece was performed, covering a 10-year period (1992–2002. The records were searched for patients with deformities related to rare disorders. These patients were reviewed as regards to characteristics of underlying disorder and spine deformity, treatment and results, complications, intraoperative and anaesthesiologic difficulties particular to each case. Results In 13 cases, the spine deformity presented in relation to rare disorders. The underlying disorder was rare neurological disease in 2 cases (Rett syndrome, progressive hemidystonia, muscular disorders (facioscapulohumeral muscular dystrophy, arthrogryposis in 2 patients, osteogenesis imperfecta in 2 cases, Marfan syndrome, osteopetrosis tarda, spondyloepiphyseal dysplasia congenita, cleidocranial dysplasia and Noonan syndrome in 1 case each. In 2 cases scoliosis was related to other congenital anomalies (phocomelia, blindness. Nine of these patients were surgically treated. Surgery was avoided in 3 patients. Conclusion This study illustrates the fact that different disorders are related with curves with different characteristics, different accompanying problems and possible complications. Investigation and understanding of the underlying pathology is an essential part of the clinical evaluation and preoperative work-up, as clinical experience at any specific center is limited.

    Full Text Available Perosomus elumbis is a rare congenital anomaly of unknown aetiology. It is characterized by errors of morphogenesis resulting in multi-organs malformations that produce a deformity of the caudal one third of the foetus. Spinal and pelvic malformations are evident, structural anomalies such as arthrogryposis of the hind limbs, ankylosis of joints, with associated malformations of the musculature. This is a case of a new born Uda lamb, with the Chief complaint of inability to stand two hours after lambing. History revealed that the dam delivered them as twins, one of which was normal. On clinical examination the lamb was recumbent but alert. The fore limbs were well developed and appeared normal. The lumbo-sacral area was excessively narrow, with a skin fold attaching the crus (Tibia and Fibula. There was an ankylosis of the stifle and hock joint and were maintained in a flexed position. The response to pin prick on the hind limb was poor. However, both anal and vulval openings were patent. Radiography revealed hypoplasia of the lumbar vertebrae, pelvic girdle, the iliac wing, the ischium and the pubis. There is a convergence of the lschial arches towards the public symphisis; the wing of the ischium is absent bilaterally. There is an ankylosis of the stifle and tarsal joints in flexed position. However, all the bones of the hind limbs are present.

    Trafficking of cargo through the endosomal system depends on endosomal fusion events mediated by SNARE proteins, Rab-GTPases, and multisubunit tethering complexes. The CORVET and HOPS tethering complexes, respectively, regulate early and late endosomal tethering and have been characterized in detail in yeast where their sequential membrane targeting and assembly is well understood. Mammalian CORVET and HOPS subunits significantly differ from their yeast homologues, and novel proteins with high homology to CORVET/HOPS subunits have evolved. However, an analysis of the molecular interactions between these subunits in mammals is lacking. Here, we provide a detailed analysis of interactions within the mammalian CORVET and HOPS as well as an additional endosomal-targeting complex (VIPAS39-VPS33B) that does not exist in yeast. We show that core interactions within CORVET and HOPS are largely conserved but that the membrane-targeting module in HOPS has significantly changed to accommodate binding to mammalian-specific RAB7 interacting lysosomal protein (RILP). Arthrogryposis-renal dysfunction-cholestasis (ARC) syndrome-associated mutations in VPS33B selectively disrupt recruitment to late endosomes by RILP or binding to its partner VIPAS39. Within the shared core of CORVET/HOPS, we find that VPS11 acts as a molecular switch that binds either CORVET-specific TGFBRAP1 or HOPS-specific VPS39/RILP thereby allowing selective targeting of these tethering complexes to early or late endosomes to time fusion events in the endo/lysosomal pathway.

    Desmosterolosis, a rare disorder of cholesterol biosynthesis, is caused by mutations in DHCR24, the gene encoding the enzyme 24-dehydrocholesterol reductase (DHCR24). To date, desmosterolosis has been described in only two patients. Here we report on a third patient with desmosterolosis who presented after delivery with relative macrocephaly, mild arthrogryposis, and dysmorphic facial features. Brain MRI revealed hydrocephalus, thickening of the tectum and massa intermedia, mildly effaced gyral pattern, underopercularization, and a thin corpus callosum. The diagnosis of desmosterolosis was established by detection of significant elevation of plasma desmosterol levels and reduced enzyme activity of DHCR24 upon expression of the patient’s DHCR24 cDNA in yeast. The patient was found to be a compound heterozygote for c.281G>A (p.R94H) and c.1438G->A (p.E480K) mutations. Structural and evolutionary analyses showed that residue R94 resides at the flavin adenine dinucleotide (FAD) binding site and is strictly conserved throughout evolution, while residue E480 is less conserved, but the charge shift substitution is accompanied by drastic changes in the local protein environment of that residue. We compare the phenotype of our patient with previously reported cases. PMID:21671375

    Background. Metaphyseal injuries resembling the classic metaphyseal lesion (CML) of abuse may occur as the result of serial casting during treatment of clubfoot deformity. Mentioned in the orthopedic literature in 1972, this iatrogenic fracture has not been described in the radiologic literature nor has the similarity to injuries occurring with abuse been previously recognized. Objective. To describe the mechanism and radiographic appearance of metaphyseal injury observed during serial casting of clubfoot. Note similarities to the CML of abuse. Materials and methods. Eight children ranging in age from 1 to 4 months underwent casting for clubfoot. Five orthopedic surgeons from three different institutions performed the casting. Two patients had spina bifida and one, arthrogryposis. A complete skeletal survey was performed on one child who was abused; there was no suspicion of abuse in the remaining seven. Results. All children manifest injury with periosteal new bone. One child had clear evidence of abuse with 24 rib fractures. X-rays of lower extremities in short leg casts revealed bilateral tibial metaphyseal fractures. Four other children had metaphyseal fractures resembling the CML of abuse, and three developed an area of sclerosis within the metaphysis. Conclusion. In the setting of serial casting for equinovarus deformity, metaphyseal injury even the CML of abuse may be noted. Since inflicted injuries are almost always unobserved and explanations rarely offered, the fact that the CML occurs as a result of orthopedic manipulation may offer some further insight concerning the pathogenesis of this well-described abuse injury.

    Full Text Available Cornelia de Lange Syndrome (CdLS (also called Bushy Syndrome or Amsterdam dwarfism, is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth, upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

    Full Text Available ntroduction: Reduced intrauterine space gives rise to ‘packaging disorder’ which may involve joint dislocations or contractures. We present an unique case where mutiple joints were dislocated involving left congenital knee dislocation (CDK, bilateral congenital hip dislocation (CDH and congenital talipes equino varus (CTEVdeformities. Case Report: A preterm baby boy born to mother with diagnosed oligohydramios presented with left CDK bilateral DDH and CTEV. The knee dislocation was treated first with gradual streaching and weekly above knee cast. At 7th week good flexion was achieved at both knees and abduction splint for DDH (using double diaper with ponseti cast for CTEV was done. At one year follow up all joints were reduced and maintained well with baby able to stand with support. Conclusion: Packaging disorders may present with multiple dislocations and deformities. Early intervention with serial casting and manipulation minimises disability and prevents ambulatory problems. In our case there was a good response to manipulation and serial casting. This differs from cases with inherent pathology like arthrogryposis where response to treatment is not so good.

    Full Text Available Carpal fusion may be seen in hereditary and nonhereditary conditions such as acrocallosal syndrome,acromegaly, Apert syndrome, arthrogryposis, Carpenter syndrome, chromosomal abnormalities, ectrodactyly-ectodermal dysplasia-cleft (EEC syndrome, the F form of acropectorovertebral dysgenesis or the F syndrome, fetal alcohol syndrome, Holt-Oram syndrome, Leopard syndrome, multiple synostosis syndrome, oligosyndactyly syndrome, Pfeiffer-like syndrome, scleroderma, split hand and foot malformation, Stickler syndrome, thalidomide embryopathy, Turner syndrome and many other conditions as mentioned in Rubinstein-Taybi's book. Sometimes there is no known causative disease.Diagnosis is usually made by plain X-ray during studying a syndrome or congenital disease or could be an incidental finding like our patients. Hand bone anomalies are more common in syndromes or other congenital or non-hereditary conditions, but polydactyly, syndactyly or oligodactyly and carpal fusions are interesting. X-ray is the modality of choice, but MRI and X-ray CT with multiplanar reconstructions may be used for diagnosis.

    Skeletal dysplasias (SDs) constitute a group of heterogeneous disorders affecting growth morphology of the chondro-osseous tissues. Prenatal diagnosis of SD is a considerable clinical challenge due to phenotypic variability. We performed a retrospective analysis of the fetal autopsies series conducted between January 2006 and December 2012 at our center. SD was detected in 54 (10%) out of 542 fetal autopsy cases which included; 11.1% thanatophoric dysplasia (n = 6), 7.4% achondroplasia (n = 4), 3.7% osteogenesis imperfect (n = 2), 1.9% Jarcho-Levin Syndrome (n = 1), 1.9% arthrogryposis (n = 1), 1.9% Dyggve-Melchior-Clausen syndrome (n = 1), 72.1% of dysostosis cases (n = 39). All SD cases were diagnosed by ultrasonography. In 20 of the cases, amniocentesis was performed, 4 cases underwent molecular genetic analyses. Antenatal identification of dysplasia is important in the management of pregnancy and in genetic counseling. Our data analysis showed that SD is usually detected clinically after the 20th gestational week. Genetic analyses for SD may provide early diagnosis and management. PMID:26376227

    Multiple pterygium syndrome (MPS) is a phenotypically and genetically heterogeneous group of rare Mendelian conditions characterized by multiple pterygia, scoliosis, and congenital contractures of the limbs. MPS typically segregates as an autosomal-recessive disorder, but rare instances of autosomal-dominant transmission have been reported. Whereas several mutations causing recessive MPS have been identified, the genetic basis of dominant MPS remains unknown. We identified four families affected by dominantly transmitted MPS characterized by pterygia, camptodactyly of the hands, vertebral fusions, and scoliosis. Exome sequencing identified predicted protein-altering mutations in embryonic myosin heavy chain (MYH3) in three families. MYH3 mutations underlie distal arthrogryposis types 1, 2A, and 2B, but all mutations reported to date occur in the head and neck domains. In contrast, two of the mutations found to cause MPS in this study occurred in the tail domain. The phenotypic overlap among persons with MPS, coupled with physical findings distinct from other conditions caused by mutations in MYH3, suggests that the developmental mechanism underlying MPS differs from that of other conditions and/or that certain functions of embryonic myosin might be perturbed by disruption of specific residues and/or domains. Moreover, the vertebral fusions in persons with MPS, coupled with evidence of MYH3 expression in bone, suggest that embryonic myosin plays a role in skeletal development. PMID:25957469

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

    Mutations in the transient receptor potential vanilloid 4 (TRPV4) gene have been associated with autosomal dominant skeletal dysplasias and peripheral nervous system syndromes (PNSS). PNSS include Charcot–Marie–Tooth disease (CMT) type 2C, congenital spinal muscular atrophy and arthrogryposis and scapuloperoneal spinal muscular atrophy. We report the clinical, electrophysiological and muscle biopsy findings in two unrelated patients with two novel heterozygous missense mutations in the TRPV4 gene. Whole exome sequencing was carried out on genomic DNA using Illumina TruseqTM 62Mb exome capture. Patient 1 harbours a de novo c.805C > T (p.Arg269Cys) mutation. Clinically, this patient shows signs of both scapuloperoneal spinal muscular atrophy and skeletal dysplasia. Patient 2 harbours a novel c.184G > A (p.Asp62Asn) mutation. While the clinical phenotype is compatible with CMT type 2C with the patient's muscle harbours basophilic inclusions. Mutations in the TRPV4 gene have a broad phenotypic variability and disease severity and may share a similar pathogenic mechanism with Heat Shock Protein related neuropathies. PMID:25900305

    Multiple pterygium syndromes include at least 15 different entities characterized by multiple pterygia or webs of the skin and multiple congenital anomalies. We describe a female infant who presented with a distinct constellation of multiple anomalies consisting of pterygia of the inguinal, intercrural and popliteal areas, flexion contractures and arthrogryposis of some joints, craniofacial anomalies including ectropion, medial canthal web, blepharophimosis, hypoplasia of nose, oral and nasopharyngeal cavities, vocal cords and tongue, micrognathia, orolabial synechiae secondary to pterygia, low set ears, alopecia, sad and expressionless face, short neck, asymmetric nipples, anal stenosis, rectal polyp, hypoplastic labia majora, complete syndactyly of all fingers and toes, pes equinovarus, bandlike web between feet, and absence of the nails and phalangeal-palmar creases. Radiological examination showed synostosis, absence or hypoplasia of metacarpal, metatarsal and phalangeal bones on feet and hands, and hypoplasia of pelvic bones and scapulae. This pattern of anomalies does not fit entirely any of the known multiple pterygium syndromes. Autosomal recessive inheritance is most likely due to the presence of three similarly affected siblings and normal parents. PMID:10925380

    Rigid equinovarus foot is a challenging problem. Talectomy has been advocated as a salvage procedure to achieve a plantigrade painless foot in the treatment of rigid equinovarus deformity. The present prospective observational study evaluated the effectiveness of talectomy in the treatment of Dimeglio grade IV rigid equinovarus feet. Nineteen feet in 13 patients were treated by talectomy from September 2001 through January 2012 (10-year, 2-month period). Of the 13 patients, 9 (69.23%) had a foot deformity due to arthrogryposis multiplex congenita and 1 (7.69%) each due to sacral agenesis, spastic cerebral palsy, neglected congenital talipes equinovarus, and post-traumatic contracture. Of the 13 patients, 9 (69.23%) were male and 4 (30.77%) were female. Their mean age was 7.7 (range 3 to 26) years. The mean follow-up duration was 6.4 (range 2 to 11) years. Along with talectomy, excision of the navicular was performed in 8 feet (42.11%), calcaneal osteotomy with a laterally based wedge in 8 (42.11%), and calcaneocuboid fusion in 3 feet (15.79%). Postoperatively, all the feet improved to Dimeglio grade II and were painless, and 16 feet (84.22%) were plantigrade; 1 foot (5.26%) had residual equinus resulting from incomplete removal of the talus and 2 (10.53%) had residual varus. Also, 3 feet (15.79%) had forefoot adduction (2 residual and 1 recurrent) that required a second surgery to correct the deformity. From our experience, talectomy is an effective procedure for correction of severe rigid equinovarus feet, provided that the talus is completely removed and the calcaneus is positioned correctly in the ankle mortise.

    Full Text Available Abstract Background Akabane virus is a member of the genus Orthobunyavirus in the family Bunyaviridae. It is transmitted by hematophagous arthropod vectors such as Culicoides biting midges and is widely distributed in temperate to tropical regions of the world. The virus is well known as a teratogenic pathogen which causes abortions, stillbirths, premature births and congenital abnormalities with arthrogryposis-hydranencephaly syndrome in cattle, sheep and goats. On the other hand, it is reported that the virus rarely induces encephalomyelitis in cattle by postnatal infection. A first large-scale epidemic of Akabane viral encephalomyelitis in cattle occurred in the southern part of Japan from summer to autumn in 2006. The aim of this study is to define the epidemiological, pathological and virological properties of the disease. Results Nonsuppurative encephalomyelitis was observed in cattle that showed neurological symptoms such as astasia, ataxia, opisthotonus and hypersensitivity in beef and dairy farms by histopathological analysis. Akabane viral antigen and genome were consistently detected from the central nervous system of these animals, and the virus was isolated not only from them but also from the blood samples of clinically healthy calves in the epidemic area. The isolates were classified into genogroup I a containing the Iriki strain, which caused encephalitis of calves almost twenty years ago in Japan. Most of the affected cattle possessed the neutralizing antibody against Akabane virus. Seroconversion of the cohabitated and sentinel cattle in the epidemic area was also confirmed during an outbreak of the disease. Conclusion The ecological and epidemiological data we have obtained so far demonstrated that the Akabane virus is not endemic in Japan. No evidence of Akabane virus circulation was observed in 2005 through nation-wide serological surveillance, suggesting that a new strain belonging to genogroup I a invaded southern Japan

    Core myopathies (CM), the main non-dystrophic myopathies in childhood, remain genetically unexplained in many cases. Heart disease is not considered part of the typical CM spectrum. No congenital heart defect has been reported, and childhood-onset cardiomyopathy has been documented in only two CM families with homozygous mutations of the TTN gene. TTN encodes titin, a giant protein of striated muscles. Recently, heterozygous TTN truncating mutations have also been reported as a major cause of dominant dilated cardiomyopathy. However, relatively few TTN mutations and phenotypes are known, and titin pathophysiological role in cardiac and skeletal muscle conditions is incompletely understood. We analyzed a series of 23 families with congenital CM and primary heart disease using TTN M-line-targeted sequencing followed in selected patients by whole-exome sequencing and functional studies. We identified seven novel homozygous or compound heterozygous TTN mutations (five in the M-line, five truncating) in 17% patients. Heterozygous parents were healthy. Phenotype analysis identified four novel titinopathies, including cardiac septal defects, left ventricular non-compaction, Emery-Dreifuss muscular dystrophy or arthrogryposis. Additionally, in vitro studies documented the first-reported absence of a functional titin kinase domain in humans, leading to a severe antenatal phenotype. We establish that CM are associated with a large range of heart conditions of which TTN mutations are a major cause, thereby expanding the TTN mutational and phenotypic spectrum. Additionally, our results suggest titin kinase implication in cardiac morphogenesis and demonstrate that heterozygous TTN truncating mutations may not manifest unless associated with a second mutation, reassessing the paradigm of their dominant expression.

In buffalo all congenital defects were hereditary (arthrogryposis, myotonia and mechano-bullous genodermatoses or suspected of being hereditary (albinism, megaesophagus and hydranencephaly/cerebellar hypoplasia. It is concluded that sporadic congenital defects are not important in the three species studied. Despite the low frequency congenital defects associated with environmental factors could be important in some regions or farms. Hereditary or probably hereditary diseases are important, not only by the mortality rates, but also because the risk of dissemination of the genes in the different breeds. In water buffalo the high prevalence of hereditary diseases was a consequence of the high consanguinity of the Brazilian buffalo population. Control measures need to be taken to avoid the spread of recessive genes in cattle and buffalo.

    Spinal muscular atrophy is a disorder of lower motor neurons, most commonly caused by recessive mutations in SMN1 on chromosome 5q. Cases without SMN1 mutations are subclassified according to phenotype. Spinal muscular atrophy, lower extremity-predominant, is characterized by lower limb muscle weakness and wasting, associated with reduced numbers of lumbar motor neurons and is caused by mutations in DYNC1H1, which encodes a microtubule motor protein in the dynein-dynactin complex and one of its cargo adaptors, BICD2. We have now identified 32 patients with BICD2 mutations from nine different families, providing detailed insights into the clinical phenotype and natural history of BICD2 disease. BICD2 spinal muscular atrophy, lower extremity predominant most commonly presents with delayed motor milestones and ankle contractures. Additional features at presentation include arthrogryposis and congenital dislocation of the hips. In all affected individuals, weakness and wasting is lower-limb predominant, and typically involves both proximal and distal muscle groups. There is no evidence of sensory nerve involvement. Upper motor neuron signs are a prominent feature in a subset of individuals, including one family with exclusively adult-onset upper motor neuron features, consistent with a diagnosis of hereditary spastic paraplegia. In all cohort members, lower motor neuron features were static or only slowly progressive, and the majority remained ambulant throughout life. Muscle MRI in six individuals showed a common pattern of muscle involvement with fat deposition in most thigh muscles, but sparing of the adductors and semitendinosus. Muscle pathology findings were highly variable and included pseudomyopathic features, neuropathic features, and minimal change. The six causative mutations, including one not previously reported, result in amino acid changes within all three coiled-coil domains of the BICD2 protein, and include a possible 'hot spot' mutation, p.Ser107Leu

    Full Text Available A artrogripose é um termo utilizado para definir a presença, ao nascimento, de múltiplas contraturas articulares. A amioplasia é a principal e mais freqüente doença que cursa com contraturas congênitas e deformidade em eqüinovaro dos pés. A maioria dessas crianças tem bom potencial para a deambulação, havendo a necessidade da correção da deformidade dos pés para a posição plantígrada. O tratamento desses pés continua sendo um desafio devido à rigidez característica da doença e ao alto risco de recidiva. Os autores apresentam as opções de tratamento com base em uma revisão ampla da literatura, discutindo as técnicas cirúrgicas convencionais, como as liberações de partes moles e a talectomia, e a correção com o aparelho de Ilizarov. Ressaltam os estudos com resultados do tratamento primário do pé artrogripótico, na tentativa de fundamentar e auxiliar o ortopedista nesta difícil escolha.Arthrogryposis is the name used to define the presence of multiple joint contractures at birth. Amyoplasia is the main and most frequent among the diseases that take place with congenital contractures and equinovarus deformity of the foot. Most of these children have a good potential for walking, and a correction is required to correct their feet to the plantigrade position. Treatment of these feet presents a challenge due to the characteristic rigidity of the disease and to the high risk of recurrence. The authors present the treatment options based on a broad review of the literature, and discuss the conventional surgical techniques, such as the release of soft tissues and talectomy, and the correction of Ilizarov's device. They point to the studies that show the results of primary treatment of the arthrogrypotic foot in an attempt of providing a basis and giving a support to the orthopedist in this difficult choice.

    Full Text Available Multi-minicore disease (MmD is an infrequent congenital myopathy, defined by structural changes in optic and electron microscopy, namely, multiple small areas lacking oxidative enzyme activity and focal disorganization of contractile proteins involving at most a few sarcomeres. The classical form of the disease manifests as more or less severe hypotonia and generalized weakness with predominance in axial and proximal limb muscles. Clinical variants also exist. Usually MmD is inherited as an autosomal recessive trait. Genetic heterogeneity is recognized and up to now mutations in the genes of RYR1 and SEPN1 have been detected. We record three unrelated cases of MmD. Case 1, with the classical benign form, was followed-up for 15 years. Case 2, presenting pharyngolaryngeal involvement and severe delay of head control, improved gradually, until independent gait was acquired at age of six years. A moderate restriction of daily life activities remains. Case 3, of antenatal-onset, was expressed by arthrogryposis of hands, predominance of scapular girdle deficit and a stable course after ten years on physiotherapy. All cases were selected by the characteristic morphological abnormalities in biceps brachii samples, including electron microscopy. Emphasis is given to case 2 due to type 1 fiber uniformity and mild endomysial fibrosis, posing a difficult differential diagnosis with congenital muscular dystrophy were it not for the significant number of multi-minicores.A miopatia dos múltiplos minifocos (MM é doença congênita rara, definida por alterações estruturais observadas ao microscópio óptico e eletrônico: múltiplas e pequenas áreas sem atividade enzimática oxidativa e desorganização focal das proteínas contráteis envolvendo poucos sarcômeros. A forma clássica da doença se manifesta com hipotonia mais ou menos grave e fraqueza generalizada, predominante em músculos axiais e proximais em membros. Entretanto, variantes cl

    complications during pregnancy are miscarriage, premature labour, hydramnios, atonic postpartum hemorrhage, difficulties during delivery, anesthetic accidents. We report the case of a healthy 37 years old pregnant, with an ordinary family anamnesis. She was diagnosed of gestational diabetes and inespecific polyhydramnios during her 30 week of pregnancy. Due to labour contractions and metrorrhagia in the 35 week she came to our emergency department. She underwent a cesarean section delivery of a male baby, who suffered severe breathing difficulties and generalized myotonia. Afterwards, the baby was diagnosticated with Steinert's congenital disease. Following genetic analysis of the mother revealed that she also suffers Steinert's disease. The diagnosis of the congenital Steinert's disease is really difficult, when the parents are unaware of the disease. Our objective is to emphasize in the importance of a good anamnesis and the characters that can be found out by ultrasound like hydramnios, reduction of fetal tone and active movements, micrognathia, arthrogryposis, that can bring us at least to a prenatal suspicion.

    años. Entre las malformaciones encontradas fueron identificadas: escoliosis congénita por segmentación (6 o 3,5%, formación (39 o 22,9%, mixta (34 o 20,0% y compleja (14 o 8.2%, escoliosis neuromuscular en la parálisis cerebral (PC (54 o 31,8%, miopatía (11 o 6,5%, artrogriposis (2 o 1,2% y escoliosis por neurofibromatosis (10 o 5,9%. CONCLUSIÓN: Hay una lista considerable de pacientes con deformidades de la columna que aguardan en lista de espera por el tratamiento quirúrgico a menudo durante un período bastante prolongado. Este hecho produce un problema social difícil de manejar cuando se añaden escoliosis neuromuscular y escoliosis congénita, es responsable de la gran mayoría de los casos en la espera de la cirugía.OBJECTIVE: Set the demographic characteristics of patients with secondary deformities of the spine waiting for surgical treatment in a tertiary hospital of high complexity. METHODS: Information was obtained from patient charts in the predefined period. The data were selected according to the criteria already presented and manipulated statistically. RESULTS: The study included a total of 170 patients, of which 94 were female aged between 1 and 58 years, and 76 males aged between 1 and 26 years. Among the deformities found the following were identified: congenital scoliosis were identified by segmentation (6 or 3.5%, formation (39 or 22.9%, mixed (34 or 20.0% and complex (14 or 8.2%, neuromuscular scoliosis in cerebral palsy (PC (54 or 31.8%, myopathy (11 or 6.5%, arthrogryposis (2 or 1.2% and scoliosis in neurofibromatosis (10 or 5.9%. CONCLUSION: There is a considerable list of patients with spinal deformities waiting for surgical treatment for a period of time often quite prolonged. This fact leads to a social problem difficult to handle and when added together, neuromuscular scoliosis and congenital scoliosis are responsible for the vast majority of cases awaiting surgery.

    planta, na primeira fase da gestação, após as primeiras chuvas, quando as ovelhas estão sendo suplementadas e a planta é o principal volumoso disponível. As malformações ocorrem principalmente nas áreas mais degradadas, onde existe maior disponibilidade da planta e menor variedade de plantas da caatinga.Congenital malformations caused by the ingestion of Mimosa tenuiflora have been reported in ruminants in the semiarid of the Brazilian Northeast. This paper reports malformations diagnosed in ruminants, from 2000 to 2008, by the Veterinary Pathology Laboratory of the Federal University of Campina Grande, Patos, PB, in municipalities of the states of Paraíba, Pernambuco and Rio Grande do Norte. During the period, 47 (3.48% out of 1.347 ascensions were reported as malformations. Based in the type of malformation and in the origin of the animals, malformations were divided in: 1 caused by the ingestion of M. tenuiflora, and 2 sporadic malformations of unknown causes. In sheep, 21 out of 418 ascensions were malformations, being 18 (4.3% of malformations caused by M. tenuiflora and 3 (0.71% of sporadic malformations. In cattle, 14 out of 434 ascensions were malformations, from these 8 (1.84% were caused by M. tenuiflora and 6 (1.38% were sporadic malformations. In goats, 12 out of 495 ascensions were malformations, being 9 (1.81% malformations related with the ingestion of M. tenuiflora and 3 (0.6% sporadic malformations. More frequent malformations caused by M. tenuiflora were arthrogryposis, micrognatia, palatoschisis, microphtalmia and unilateral or bilateral hypoplasia or aplasia of the incisive bones. Sporadic malformations were acephaly and hermaphrodite, dicephaly and malformations of mesenteric vessel in sheep; atresia ani in three goats; and hydranencephaly, atresia ani, ribs malformation with eventracion, cerebellar hypoplasia with hydrocephalus, pulmonary choristoma and meningocele, and siamese twins in cattle.

    ,flexion contractures of multiple joints(elbow,knee,hip,and finger),kyphoscoliosis,muscular hypoplasia,and abnormal pinnae("crumpled" outer helices).Molecular genetic testing showed mutation in the fibrillin-2(FBN2)gene encoding the extracellular matrix microfibril.Four cases were followed up for 6~9 months.Results After operation the average Cobb angle of the scoliosis and kyphosis were 37.6° (35°~52°)and 38.6°(28°~54°)immediately,with 62.3%and 68.7% curve correction respectively.Three cases got excellent synostosis of posterior lamina,1 case underwent revision with lamina hook because the distal screw was loose and hurt the nerve root,and the other 2 cases lost follow-up.The patients'body appearance and pulmonary function were obviously improved. Conclusion The characteristic clinical manifestation include severe and stiff kyphoscoliosis,difficult to correct,and enhanced Cobb angle,and pedicle dysplasia of vertebral pedicle leading to difficulty in installing screws.Smith-Petersen osteotomy is often necessary.CCA should be differentiated with Marfan syndrom(MFS),Stickler syndrome,Homocystinuria,and distal arthrogryposis,especially MFS.
