1/37. The C.C.A. syndrome (congenital contractural arachnodactyly): a new differential syndrome for Marfan's syndrome and homocystinuria.The first case in the dental literature of congenital contractural arachnodactyly (C.C.A. syndrome) is presented. This newly delineated syndrome is an autosomal dominant heritable disorder of connective tissue. Its similarities to Marfan's syndrome and homocystinuria, as well as other syndromes, are discussed. The lack of cardiovascular disease, specific ocular anomalies, and mental retardation are presented in the differential diagnosis of the C.C.A syndrome with Marfan's syndrome and homocystinuria.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/37. Mitochondrial complex I deficiency in a female with multiplex arthrogryposis congenita.A 10-year-old female with arthrogryposis multiplex congenita is presented. Clinical, neurophysiologic, and histologic findings suggested a mild myopathy. The analysis of enzymatic activity in the homogenate and of mitochondrial function in saponin-permeabilized fibers from the muscle biopsy revealed an approximately twofold-decreased specific activity of the NADH:CoQ oxidoreductase (complex I of the mitochondrial respiratory chain) that was compensated for by an increased number of mitochondria. The complex I deficiency was also detected in cultivated skin fibroblasts of the patient. The observed defect of mitochondrial oxidative phosphorylation in arthrogryposis multiplex congenita may be of pathogenetic relevance.- - - - - - - - - - ranking = 57.821135049391keywords = myopathy (Clic here for more details about this article) |
3/37. Cystic hygroma colli as the first echographic sign of the fetal akinesia sequence.We report first trimester cystic hygroma colli with subsequent resolution and development of a fetal akinesia deformation sequence. Neuropathological examination of the brain showed intra- and extracellular white matter edema while spinal cord, peripheral nerves and muscles were normal. Hygroma colli as the first echographic sign of subsequent severe fetal akinesia sequence without muscular dystrophy as seen in the Lethal Multiple pterygium syndrome has not been previously reported.- - - - - - - - - - ranking = 310.13559075322keywords = muscular dystrophy, dystrophy (Clic here for more details about this article) |
4/37. Neonatal arthrogryposis and absent limb muscles: a muscle developmental gene defect?We describe a child who presented at birth with arthrogryposis. Following a muscle biopsy a diagnosis of congenital muscular dystrophy was made and a skin biopsy 12 years later confirmed the presence of merosin. Her clinical picture was unusual, however, for merosin-positive congenital muscular dystrophy. She had extreme wasting and weakness of her arms and legs. In contrast, she had good neck and trunk control, and no facial or respiratory muscle weakness. We have used magnetic resonance imaging to examine the pattern of muscle involvement in this case. No recognizable muscle could be identified in the limbs. In contrast, the axial muscles were preserved. This striking pattern of virtual absence of muscles in the limbs with sparing of the axial muscle suggests that a gene responsible for the migration and/or proliferation of limb muscle precursor cells may be involved in the disease process. It is recognized that merosin-positive congenital muscular dystrophy is a heterogeneous disease. magnetic resonance imaging is a useful tool for examining in detail the pattern of muscle involvement and identifying individual phenotypes. Understanding more about which muscles are affected in children with congenital myopathies may provide information on the underlying pathological process and help in the search for candidate proteins and genes.- - - - - - - - - - ranking = 930.40677225965keywords = muscular dystrophy, dystrophy (Clic here for more details about this article) |
5/37. prenatal diagnosis of arthrogryposis multiplex congenita with increased nuchal translucency but without any underlying fetal neurogenic or myogenic pathology.arthrogryposis multiplex congenita is a general term for congenital multiple joint contractures, the aetiology of which is variable. prenatal diagnosis is usually based on the detection of diminished fetal movements and joint contractures on ultrasound. There are also reports of early diagnosis of arthrogryposis in the first and early second trimester by detection of subcutaneous oedema. We report another case of arthrogryposis multiplex congenita with increased nuchal translucency and scoliosis diagnosed by ultrasonography at 15 weeks of gestation. The pregnancy was terminated at the request of the parents. Post-mortem examination revealed that it was not associated with fetal myopathy or neuropathy. Multiple joint contractures with increased nuchal translucency without any underlying fetal neurogenic and myogenic pathology may be a distinct form of arthrogryposis multiplex congenita.- - - - - - - - - - ranking = 57.821135049391keywords = myopathy (Clic here for more details about this article) |
6/37. infant with high arched palate, bell-shaped chest, joint contractures, and intrauterine fractures.A case is presented of a female newborn infant delivered with an apgar score of 1, who could not be resuscitated. There was a high arched palate, bell-shaped chest, contractures of writes inflexion, ankles and knees in extension, and intrauterine fractures. Clinical discussion led to a diagnosis of arthrogryposis secondary to fetal akinesia syndrome caused by nemaline myopathy. pathology and pathologic discussion confirmed this diagnosis.- - - - - - - - - - ranking = 57.821135049391keywords = myopathy (Clic here for more details about this article) |
7/37. Distal arthrogryposis type IIB: unreported ophthalmic findings.We describe four members spanning three generations of a Caucasian family affected with distal arthrogryposis (DA). Based on Hall's original classification, we have placed our family under type IIB and present previously unreported ophthalmic features. All the members had different degrees of ophthalmoplegia, ptosis, astigmatism, and strabismus. Other findings in affected family members included keratoconus in the index patient, which was associated with abnormal electron microscopy of the affected cornea and increased thickness of the central cornea, small axial length of the globe and choroidal folds in the others.- - - - - - - - - - ranking = 15.493582357328keywords = ophthalmoplegia (Clic here for more details about this article) |
8/37. Goniodysgenesis of the eye with arthrogryposis multiplex congenita.We report an autopsy case of 4-day-old male infant with arthrogryposis multiplex congenita studied by histological methods in respect to the ocular tissues. The eye examined was normal in size, and the retina, optic nerve, choroid, sclera and extracocular muscle showed no remarkable histological changes. However, the cornea was thickened, and the iris, trabecular tissue and ciliary body showed maldevelopmental changes, which were all compatible with goniodysgenesis. The clinical data of this case did not demonstrate any signs of congenital glaucoma, but the present study indicates that an infant with arthrogryposis multiplex congenita has a potential for infantile glaucoma with goniodysgenesis.- - - - - - - - - - ranking = 2keywords = ocular (Clic here for more details about this article) |
9/37. Involvement of the larynx in a congenital "myopathy", unilateral aplasia of the arytenoid, micrognathia, and malformation of the brain--a new syndrome?Neuromyopathic changes were found in various limb muscles and in intrinsic laryngeal muscles of a two month old girl. She had been noted to have micrognathia, arthrogryposis and congenital stridor and died as a result of respiratory insufficiency and aspiration. autopsy revealed an absent left arytenoid cartilage and severe histogenic abnormalities of the brain. Although the muscles involved showed a mainly myopathic pattern, marked signs of peripheral neurogenic involvement were present. These differed from motor neuron disease or aplasia of anterior horn cells. These findings cast a new light on the discussion of unclassified congenital myopathy resembling the picture of congenital muscular "dystrophy". This is the first case of congenital neuromyopathy in which involvement of intrinsic laryngeal muscles has been demonstrated morphologically.- - - - - - - - - - ranking = 364.97816691067keywords = myopathy, dystrophy (Clic here for more details about this article) |
10/37. A new syndrome of myopathy with muscle spindle excess.arthrogryposis may result from various neuromuscular or connective tissue disorders leading to in utero hypokinesia or akinesia and the prenatal development of joint contractures. We report the case of a preterm neonate born with arthrogryposis and flaccid quadriplegia that led to the diagnosis of myopathy with muscle spindle excess. The rare and unusual histopathologic abnormality associated with the myopathy illustrated in this case has been described in only three other cases in the medical literature. The concurrence of hypertrophic cardiomyopathy, arthrogryposis, and myopathy with muscle spindle excess suggests the presence of a newly described syndrome. This case clearly demonstrates that specific prenatal ultrasonographic findings combined with the presenting clinical manifestations should promptly raise the suspicion of a neuromuscular disorder.- - - - - - - - - - ranking = 462.56908039513keywords = myopathy (Clic here for more details about this article) |
