    Fukuyama congenital muscular dystrophy is a genetic disease and common in Japan. The typical clinical features are hypotonia with an early infantile onset and severe developmental delay. The diagnosis is based on pathologic evidence of muscular dystrophy revealed by biopsy or an increased serum creatine kinase levels. Involvement of the brain is characterized by abnormal cerebral cortical dysplasia, cerebellar dysplasia, and white matter changes. We encountered a case of Fukuyama congenital muscular dystrophy in which brain MRI findings were typical, and present this case together with a review of the literature

    Fukuyama congenital muscular dystrophy (FCMD), the second most common muscular dystrophy in the Japanese population, is an autosomal recessive disorder caused by mutations in the fukutin (FKTN) gene. The main features of FCMD are a combination of infantile-onset hypotonia, generalized muscle weakness, eye abnormalities and central nervous system involvement with mental retardation and seizures associated with cortical migration defects. The FKTN gene product is thought to be necessary for maintaining migrating neurons in an immature state during migration, and for supporting migration via α-dystroglycan in the central nervous system. Typical magnetic resonance imaging findings in FCMD patients are cobblestone lissencephaly and cerebellar cystic lesions. White matter abnormalities with hyperintensity on T(2)-weighted images are seen especially in younger patients and those with severe phenotypes. Most FCMD patients are mentally retarded and the level is moderate to severe, with IQs ranging from 30 to 50. In our recent study, 62% of patients developed seizures. Among them, 71% had only febrile seizures, 6% had afebrile seizures from the onset, and 22% developed afebrile seizures following febrile seizures. Most patients had seizures that were controllable with just 1 type of antiepileptic drug, but 18% had intractable seizures that must be treated with 3 medications.

    Fukuyama type congenital muscular dystrophy (FCMD) has been attracting attention in recent years because of its brain malformation and progressive muscular dystrophy. The intravitam recognition of brain malformation has been remarkably enhanced by the advent of noninvasive neuroimaging techniques such as CT and MRI. In this study, 87 cranial CT scans and 22 MRIs of the brain, carried out on 60 patients with FCMD, were systematically surveyed, and the correlation between neuroradiological findings and clinical disabilities, and, in two autopsy cases, neuropathological findings was evaluated. Four cases of lissencephalic, 29 of pachygyric, and one of polymicrogyric (suspected) brain surface, and 2 normal brain surfaces were recognized. The patients with lissencephalic brain surface were compared using Dobyns' criteria. Grading of pachygyria was judged as bilateral II in 52% of cases and bilateral I in 48%. The surface of the occipital lobe could not be confirmed with either CT or MRI. Polymicrogyria was suspected using MRI but could not confirmed with CT. Five caces of lissencephaly had never learned any meaningful words and all but one were bedridden because of poor head control. The abilities of patients were better when the grading of pachygyria was milder. Mental disability and peak motor function correlate more closely with the degree and extent of brain malformation than with muscle degeneration. The decrease in radiodensity in the white matter was remarkable in 12 out of 19 cases (63%), and was usually bilaterally symmetrical. An increase in radiodensity in the white matter with age was observed in 3 patients. The rate of myelination was slower than normal in 3 out of the 6 cases. (author)

    The Fukuyama type congenital muscular dystrophy (F-CMD) has been generally recognized as a well delineated subgroup of progressive muscular dystrophy (PMD) with uniform clinical, pathological, and genetic features. However, there are still debate to be solved as to the etiology of the condition, because several neuropathological findings found in F-CMD brain allowed some investigators to hypothesize the intrauterine infection to be a primary causation. The authors reported here two families with two affected siblings in each. In the pedigree A, consanguineous parents produced two sisters, Case 1 (3-year-old) and Case 2 (14-month-old). Two patients in the pedigree B, the products of non-consanguineous parents, Case 3 (4-month-old male) and his elder sister already decreased, were affected with F-CMD and infantile spasms. In all cases, generalized weakness and hypotonia had been remarkable since their early infancy, and muscle atrophy, myopathic facies multiple joint contractures and mental dullness became evident gradually. The above-mentioned clinical features as well as laboratory findings including elevated serum CPK and myogenic EMG were compatible with those of typical F-CMD. However, they were characterized by the following three unusual features. 1. Muscle biopsy: In addition to an overwhelming myogenic change, there was a distinct inflammatory cell infiltration in all cases, and scattered small groups of atrophic fibers were present in Case 2. 2. Brain CT scanning: A symmetrical and extensive low density area was observed in the cerebral white matter in all cases. 3. A favorable response to prednisolone therapy was noted in all cases.

    Central-nervous system involvement in 26 patients with congenital muscular dystrophy (CMD) was studied using computed tomography (CT). CT was carried out using the EMI-1000 or 1010. The most characteristic finding in the CT was a low-density area in the white matter, seen in 15 out of the 26 (58%). Ventricular dilatation was also noted in 21 out of the 26 (80%), and cortical atrophy in 16 (65%). In one case, asymmetry of the lateral ventricle was observed. Half of the patients had a low-density area in the white matter in addition to cerebral atrophy, while only three (12%) showed normal CT findings. From the relation between the CT findings and IQ in patients with CMD, those with a low-density area in addition to cerebral atrophy and those with cerebral atrophy alone had extremely low IQs compared with those with a low-density area and with normal CT findings. From the relation between the CT findings and the EEG in patients with CMD, seizure discharges, such as a spike or a sharp wave complex and a spike, were most frequently seen in those with a low-density area in the white matter in addition to cerebral atrophy, and among those patients epileptic seizures occurred in three. From the relation between the CT findings and the stage of disability in patients with CMD, those with a low-density area in addition to cerebral atrophy showed severe motor disability. From the relation between CT findings and age in patients with CMD, severe CT findings were seen in the younger group. On ophthalmological examination, one of the most important findings was the evident bulateral optic nerve atrophy noted in several cases. (J.P.N.)

    The Fukuyama type congenital muscular dystrophy (F-CMD) has been generally recognized as a well delineated subgroup of progressive muscular dystrophy with uniform clinical and pathological features. But the pathogenesis is not yet clear. Two theories have been proposed ; autosomal recessive inheritance and intrauterine infection. We experienced a female case of F-CMD, and tried serial brain CT scanning from the birth to one year of age. Low density changes of white matter were not found at the first day of her life. But marked brain atrophy and low density changes of white matter were found after three months. We propose that CT examination should be repeated from early stage to clarify the pathogenesis of F-CMD. (AUTHOR)

    Patients with Fukuyama-type congenital muscular dystrophy sometimes experience transient exacerbations of muscle weakness. We took care of a 9-year-old boy with Fukuyama-type congenital muscular dystrophy who presented with acute respiratory failure and decreased exercise ability with marked elevation of serum creatine kinase indicating rhabdomyolysis. At that time, his younger sister suffered from erythema infectiosum. Although he had no particular symptoms, he was tested and proven to have acute human parvovirus B19 infection based on detection of anti-B19 IgM and parvovirus B19 DNA in his serum. His acute rhabdomyolysis was possibly triggered by human parvovirus B19 infection. © The Author(s) 2013.

    Fukuyama type congenital muscular dystrophy (FCMD) is an autosomal recessive disease, exhibiting muscular dystrophy, and central nervous system (CNS) and ocular malformations. It is included in alpha-dystroglycanopathy, a group of muscular dystrophy showing reduced glycosylation of alpha-dystroglycan. alpha-Dystroglycan is one of the components of dystrophin-glycoprotein complex linking extracellular and intracellular proteins. The sugar chains of alpha-dystroglycan are receptors for extracellular matrix proteins such as laminin. Fukutin, a gene responsible for FCMD, is presumably related to the glycosylation of alpha-dystroglycan like other causative genes of alpha-dystroglycanopathy. The CNS lesion of FCMD is characterized by cobblestone lissencephaly, associated with decreased glycosylation of alpha-dystroglycan in the glia limitans where the basement membrane is formed. Astrocytes whose endfeet form the glia limitans seem to be greatly involved in the genesis of the CNS lesion. Fukutin is probably necessary for astrocytic function. Other components of the CNS may also need fukutin, such as migration and synaptic function in neurons. However, roles of fukutin in oligodendroglia, microglia, leptomeninges and capillaries are unknown at present. Fukutin is expressed in various somatic organs as well, and appears to work differently between epithelial cells and astrocytes. In the molecular level, since the dystrophin-glycoprotein complex is linked to cell signaling pathways involving c-src and c-jun, fukutin may be able to affect cell proliferation/survival. Fukutin was localized in the nucleus on cancer cell lines. With the consideration that mutations of fukutin give rise to wide spectrum of the clinical phenotype, more unknown functions of fukutin besides the glycosylation of alpha-dystroglycan can be suggested. Trials for novel treatments including gene therapy are in progress in muscular dystrophies. Toward effective therapies with minimal side effects, precise

    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).

    Abnormalities of dystrophin, a cytoskeletal protein of muscle and nerve, are generally considered specific for Duchenne and Becker muscular dystrophy. However, several patients have recently been identified with dystrophin deficiency who, before dystrophin testing, were considered to have Fukuyama congenital muscular dystrophy (FCMD) on the basis of clinical findings. Epidemiologic data suggest that only 1/3,500 males with autosomal recessive FCMD should have abnormal dystrophin. To explain the observation of 3/23 FCMD males with abnormal dystrophin, the authors propose that dystrophin and the FCMD gene product interact and that the earlier onset and greater severity of these patients' phenotype (relative to Duchenne muscular dystrophy) are due to their being heterozygous for the FCMD mutation in addition to being hemizygous for Duchenne muscular dystrophy, a genotype that is predicted to occur in 1/175,000 Japanese males. This model may help explain the genetic basis for some of the clinical and pathological variability seen among patients with FCMD, and it has potential implications for understanding the inheritance of other autosomal recessive disorders in general. For example, sex ratios for rare autosomal recessive disorders caused by mutations in proteins that interact with X chromosome-linked gene products may display predictable deviation from 1:1.

  15. Roles of Fukutin, the Gene Responsible for Fukuyama-Type Congenital Muscular Dystrophy, in Neurons: Possible Involvement in Synaptic Function and Neuronal Migration

    Fukutin is a gene responsible for Fukuyama-type congenital muscular dystrophy (FCMD), accompanying ocular and brain malformations represented by cobblestone lissencephaly. Fukutin is related to basement membrane formation via the glycosylation of α-dystoglycan (α-DG), and astrocytes play a crucial role in the pathogenesis of the brain lesion. On the other hand, its precise function in neurons is unknown. In this experiment, the roles of fukutin in mature and immature neurons were examined using brains from control subjects and FCMD patients and cultured neuronal cell lines. In quantitative PCR, the expression level of fukutin looked different depending on the region of the brain examined. A similar tendency in DG expression appears to indicate a relation between fukutin and α-DG in mature neurons. An increase of DG mRNA and core α-DG in the FCMD cerebrum also supports the relation. In immunohistochemistry, dot-like positive reactions for VIA4-1, one of the antibodies detecting the glycosylated α-DG, in Purkinje cells suggest that fukutin is related to at least a post-synaptic function via the glycosylation of α-DG. As for immature neurons, VIA4-1 was predominantly positive in cells before and during migration with expression of fukutin, which suggest a participation of fukutin in neuronal migration via the glycosylation of α-DG. Moreover, fukutin may prevent neuronal differentiation, because its expression was significantly lower in the adult cerebrum and in differentiated cultured cells. A knockdown of fukutin was considered to induce differentiation in cultured cells. Fukutin seems to be necessary to keep migrating neurons immature during migration, and also to support migration via α-DG

Hypoperfusion was detected in 8 patients on Tl-201 SPECT. Decreases in both systolic function (left ventricular ejection fraction; LVEF) and diastolic function (peak filling rate; PFR) were also seen in these patients. A high incidence of myocardial involvement of these kinds of progressive muscular dystrophy was suggested. (author)

    The classification of congenital muscular dystrophies (CMD), based on perceived clinical and morphological similarities or differences, is controversial. CMD without cerebral involvement has sometimes been divided into a mild and a severe form. This distinction is, however, arbitrary and not uncontested. Whether Ullrich's disease, formerly called atonic-sclerotic dystrophy, is a disease entity and if so, whether it is a primary muscle disorder, is uncertain. CMD without cerebral involvement is inherited in an autosomal recessive fashion in the great majority of cases. CMDs with cerebral involvement are usually classified into at least three forms: the Fukuyama type of CMD, occurring almost exclusively in Japanese patients; CMD with hypomyelination, sometimes also called the occidental type of cerebromuscular dystrophy; and Walker-Warburg syndrome. Muscle-eye-brain disease, described in a number of Finnish patients, may or may not belong in this last category. In CMD with cerebral involvement inheritance is also autosomal recessive. It is possible that single sporadic cases are phenocopies due to infectious or other exogenous causes. Reports of clinical and morphological findings from an increasing number of patients show a high degree of variability within and, on the other hand, certain similarities between the forms of CMD with cerebral involvement. In addition, neuroradiological changes are also found with increasing frequency in CMD patients without clinical neuropsychological abnormalities. It is not unreasonable to speculate that molecular genetic techniques will reveal in the near future a variable defect in one gene locus or defects in a few gene loci as the cause of the various clinical forms of CMDs.

    Muscle CT scans were performed in order to compare the characteristic distribution of progressive muscle involvement in the early stages of Duchenne type (DMD) and Fukuyama type muscular dystrophy (FCMD). Muscle images at the levels of the 3rd lumbar vertebra, thigh and calf were assessed by visual inspection, and mean CT numbers calculated for individual muscles were statistically analysed. On visual inspection, intramuscular low density areas and muscular atrophy were observed in the muscles of older patients with either disease. These changes were, however, more extensive at thigh level in DMD, and at calf level in FCMD. Nevertheless, the mean CT numbers of muscles in which only slight changes were grossly visible on CT scans displayed progressive decreases with increasing age. Moreover, a significant negative relationship was recognizable between age and mean CT number in almost all muscles examined. Comparison of the slopes of the regression lines revealed that the so-called selective pattern of muscle involvement characteristic of the symptomatic stage had already partially manifested in the preclinical or early stages of both diseases. In FCMD, the rates of decrease in CT numbers were extremely rapid for calf muscles as compared with those in DMD, indicating that this is one reason for FCMD patients never becoming ambulatory. However, for almost all of the other muscles, the CT numbers in FCMD decreased in parallel with the corresponding CT numbers in DMD; thus, these diseases displayed a similarity in the pattern of muscle involvement, despite their different pathogenetic mechanisms and inheritance patterns.

    The involvements of central nervous system in those cases of congenital muscular dystrophy (CMD), especially in Fukuyama type CMD, have been observed both radiologically and pathologically. The recent development of MRI made it easier to detect fine structural changes in brain matter than the X-ray CT. Then, we tried to evaluate the central nervous system abnormalities of six cases of CMD by both X-ray CT and MRI. In one case, X-ray CT revealed diffuse hypodensity of cerebral white matter, and MRI showed high intensity on long spin-echo image and low intensity on inversion-recovery image. In another case, X-ray CT showed no abnormal findings, but long spin-echo image revealed two high intensity spots in cerebral white matter. In other four cases, brain atrophy was demonstrated by X-ray CT and/or MRI, one case of these patients had bilateral congenital arachnoid cysts in the middle cranial fossa and hypogenesis of temporal lobes. Although we could not demonstrate polymicrogyria and agyria in all cases by MRI, white matter changes and structural changes were revealed more clearly than X-ray CT. The combination of X-ray CT and MRI seems to make a noteworthy contribution to estimate the central nervous system abnormalities in CMD. (author)

    This study was carried out to investigate the process of muscle involvement according to age in patients with FCMD (Brain Dev 1981 ; 3:1 - 29) by CT scans. Fourteen patients with FCMD I (age: 5 months-12 years) and two patients with FCMD III or IV (age: 3, 4 years) were studied. The midcalf, midthigh, L3 and shoulder girdle level were the sites chosen. Two types of change were found in FCMD I. One of them was the attenuation of the density in muscle and the other one was decreased area of muscle as a result of low density which started from periphery of the muscle. The latter was found in m. psoas major after age 9, whilst the former was found in other muscles to some degree. The severity of the changes was related to age. In the case which was examined twice, the changes extended even better motor function had been attained. The changes in midcalf preceded those in midthigh, L3, shoulder girdle. The attenuation of density was found early and severely in m. triceps surae, m. adductor magnus, paravertebral muscles and m. subscapularis, whilst those in m. tibialis anterior and posterior, m. gracilis, m. sartorius, m. quadratus lumborum appeared later and relatively mild. The relationship between the process of extension of low density in muscle and joint contractures were also discussed. The changes in CT scan in FCMD III or IV were milder than those of FCMD I and there was no tendency that the change in midcalf preceded those of other scanned level.

The serum muscle enzimes were normal and the needle electromyography showed active and chronic denervation. The muscle biopsy demonstrated active and chronic denervation compatible with spinal muscular atrophy. Analysis of exons 7 and 8 of survival motor neuron gene through polymerase chain reaction did not show deletions. Neurogenic muscular atrophy is a new abnormality associated with CCA, suggesting that CCA is clinically heterogeneous.

Syndromic congenital muscular dystrophies are clinically similar autosomal recessive disorders characterized by congenital muscular dystrophy, lissencephaly, and eye anomalies. We present a case of a rare form of syndromic congenital muscular dystrophy in an eight year old girl, born of first- degree consanguinity. She had: global developmental delay; a seizure disorder; hypotonia; progressive muscle contractures including bilateral symmetrical flexion contractures of hips, knees, equinus contracture and thoracolumbar scoliosis; diminished deep tendon reflexes: bilateral premature cataract; pseudophakia; and nystagmus. The patient was also highly myopic. Based on clinical features, muscle biopsy and MRI of the brain, a diagnosis of muscle- eye- brain disease was made. Identification of these patients may help to prevent this crippling disorder in the future siblings of probands by utilizing genetic counselling and mutation analysis.

    This study was carried out to investigate the process of muscle involvement according to age in patients with FCMD (Brain Dev 1981 ; 3:1 - 29) by CT scans. Fourteen patients with FCMD I (age: 5 months-12 years) and two patients with FCMD III or IV (age: 3, 4 years) were studied. The midcalf, midthigh, L3 and shoulder girdle level were the sites chosen. Two types of change were found in FCMD I. One of them was the attenuation of the density in muscle and the other one was decreased area of muscle as a result of low density which started from periphery of the muscle. The latter was found in m. psoas major after age 9, whilst the former was found in other muscles to some degree. The severity of the changes was related to age. In the case which was examined twice, the changes extended even better motor function had been attained. The changes in midcalf preceded those in midthigh, L3, shoulder girdle. The attenuation of density was found early and severely in m. triceps surae, m. adductor magnus, paravertebral muscles and m. subscapularis, whilst those in m. tibialis anterior and posterior, m. gracilis, m. sartorius, m. quadratus lumborum appeared later and relatively mild. The relationship between the process of extension of low density in muscle and joint contractures were also discussed. The changes in CT scan in FCMD III or IV were milder than those of FCMD I and there was no tendency that the change in midcalf preceded those of other scanned level. (author)

    Congenital muscular torticollis (CMT) is due to contracture of the sternocleidomastoid muscle which may cause activity limitations of the neck, tilt of the head, craniofacial asymmetry, and deformity of the skull. The authors present their experience of arthroscopic tight fibrous band release with radiofrequency in teenagers under local anesthesia and evaluate the clinical results. A total of 69 patients who underwent arthroscopic release of CMT with radiofrequency under local anesthesia by a single surgeon could participate in this study. Before operation, surface landmarks of sternocleidomastoid muscle, bone, and neurovascular structures were marked. Local infiltrating anesthesia of the surgical region was then performed. Through a working space created by blunt dissection, the arthroscopy and radiofrequency devices were introduced. Then, the clavicular and sternal heads of the sternocleidomastoid muscle were identified and gradually transected. The patients were followed up postoperatively with Cheng's scoring system. There were 31 male patients and 38 female patients. The mean age of the patients was 16.1 years. The mean length of follow-up in this series was 36.7 months (range, 28 to 67 months). During the operation, 62 patients (89.9%) had no pain, 6 patients (8.7%) felt mild pain, and only 1 patient (1.4%) regarded the procedure as very painful. At all follow-up periods, there were no repeat arthroscopies for any of these patients. At the final follow-up, the average rotation deficit improved from 22.5° to 4.1° postoperatively, and the average lateral bending deficit improved from 14.6° to 3.3° (p radiofrequency under local anesthesia provides surgeons with an alternative to traditional open techniques for the management of congenital muscular torticollis (CMT). Our date shows that this method is minimally invasive and provides good functional recovery with a lower risk of complications.

    Dystroglycanopathies are a subset of congenital muscular dystrophies wherein α-dystroglycan (α-DG) is hypoglycosylated. α-DG is an extensively O-glycosylated extracellular matrix-binding protein and a key component of the dystrophin-glycoprotein complex. Previous studies have shown α-DG to be post-translationally modified by both O-GalNAc- and O-mannose-initiated glycan structures. Mutations in defined or putative glycosyltransferase genes involved in O-mannosylation are associated with a loss of ligand-binding activity of α-DG and are causal for various forms of congenital muscular dystrophy. In this study, we sought to perform glycomic analysis on brain O-linked glycan structures released from proteins of three different knock-out mouse models associated with O-mannosylation (POMGnT1, LARGE (Myd), and DAG1(-/-)). Using mass spectrometry approaches, we were able to identify nine O-mannose-initiated and 25 O-GalNAc-initiated glycan structures in wild-type littermate control mouse brains. Through our analysis, we were able to confirm that POMGnT1 is essential for the extension of all observed O-mannose glycan structures with β1,2-linked GlcNAc. Loss of LARGE expression in the Myd mouse had no observable effect on the O-mannose-initiated glycan structures characterized here. Interestingly, we also determined that similar amounts of O-mannose-initiated glycan structures are present on brain proteins from α-DG-lacking mice (DAG1) compared with wild-type mice, indicating that there must be additional proteins that are O-mannosylated in the mammalian brain. Our findings illustrate that classical β1,2-elongation and β1,6-GlcNAc branching of O-mannose glycan structures are dependent upon the POMGnT1 enzyme and that O-mannosylation is not limited solely to α-DG in the brain.

    Full Text Available The congenital muscular dystrophies (CMDs are a group of genetically and clinically heterogeneous hereditary myopathies with preferentially autosomal recessive inheritance, that are characterized by congenital hypotonia, delayed motor development and early onset of progressive muscle weakness associated with dystrophic pattern on muscle biopsy. The clinical course is broadly variable and can comprise the involvement of the brain and eyes. From 1994, a great development in the knowledge of the molecular basis has occurred and the classification of CMDs has to be continuously up dated. We initially present the main clinical and diagnostic data concerning the CMDs related to changes in the complex dystrophin-associated glycoproteins-extracellular matrix: CMD with merosin deficiency (CMD1A, collagen VI related CMDs (Ullrich CMD and Bethlem myopathy, CMDs with abnormal glycosylation of alpha-dystroglycan (Fukuyama CMD, Muscle-eye-brain disease, Walker-Warburg syndrome, CMD1C, CMD1D, and the much rarer CMD with integrin deficiency. Finally, we present other forms of CMDs not related with the dystrophin/glycoproteins/extracellular matrix complex (rigid spine syndrome, CMD1B, CMD with lamin A/C deficiency, and some apparently specific clinical forms not yet associated with a known molecular mechanism.

    Congenital muscular torticollis (CMT) is characterized by shortening or excessive contraction of the sternocleidomastoid muscle (SCM). The main purpose of this study was to evaluate the feasibility of quantifying SCM stiffness using acoustic radiation force impulse (ARFI) sonoelastography in infants with CMT. Twenty infants with an SCM thickness greater than 10 mm with or without involvement of the entire SCM length (limitation of neck rotation passive range of motion [PROM]: group 1S >30°, group 1M = 15°-30°) and 12 infants with an SCM thickness smaller than 10 mm with or without involvement of any part of SCM (group 2) were included. The SCM thickness was measured using real time B-mode ultrasound, and the local SCM shear wave velocity (SWV) and subcutaneous fat layer using ARFI sonoelastography. The neck rotation PROM was significantly greater in group 1S (36.5° ± 5.3°) than in group 1M (18.8° ± 4.9°; P SCM in the affected side (2.96 ± 0.99 m/s) was significantly higher than that in the unaffected side (1.50 ± 0.30 m/s; P SCM was significantly higher in group 1S than in group 1M. There was significant correlation between the degree of PROM deficit of neck rotation and the SWV of the affected SCM (r = .75; P SCM in relationship to the limitation of neck rotation PROM in infants with CMT, if there was no difference in SCM thickness among infants.

    This case report describes the effects of a 6-week progressive tap dance program on static and dynamic balance for a child with type 1 congenital myotonic muscular dystrophy (congenital MMD1). A 6-year-old girl with congenital MMD1 participated in a 1-hour progressive tap dance program. Classes were held once a week for 6 consecutive weeks and included 3 children with adaptive needs and 1 peer with typical development. The Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2) balance subsection and the Pediatric Balance Scale were completed at the beginning of the first class and the sixth class. The participant's BOT-2 score improved from 3 to 14. Her Pediatric Balance Scale score did not change. Participation in a progressive tap dance class by a child with congenital MMD1 may facilitate improvements in static and dynamic balance.

    Full Text Available Megaconial congenital muscular dystrophy (OMIM 602541 is characterized with early-onset hypotonia, muscle wasting, proximal weakness, cardiomyopathy, mildly elevated serum creatine kinase (CK levels, and mild-to-moderate intellectual disability. We report two siblings in a consanguineous family admitted for psychomotor delay. Physical examination revealed proximal muscle weakness, contractures in the knee of elder sibling, diffuse mild generalized muscle atrophy, and dry skin with ichthyosis together with multiple nummular eczema in both siblings. Serum CK values were elevated up to 500 U/L. For genetic work-up, we performed whole exome sequencing (WES after Nimblegen enrichment on the Illumina platform. The WES revealed a novel homozygous missense mutation in the Choline Kinase-Beta (CHKB gene c.1031G>A (p.R344Q in exon 9. Ichthyosis-like skin changes with intense pruritus and nummular eczema may lead to clinical diagnosis in cases with megaconial congenital muscular dystrophy.

    Full Text Available OBJECTIVE: Respiratory complications are the main causes of morbidity and mortality in patients with neuromuscular disease (NMD. The objectives of this study were to determine the effects that routine daily home air-stacking maneuvers have on pulmonary function in patients with spinal muscular atrophy (SMA and in patients with congenital muscular dystrophy (CMD, as well as to identify associations between spinal deformities and the effects of the maneuvers. METHODS: Eighteen NMD patients (ten with CMD and eight with SMA were submitted to routine daily air-stacking maneuvers at home with manual resuscitators for four to six months, undergoing pulmonary function tests before and after that period. The pulmonary function tests included measurements of FVC; PEF; maximum insufflation capacity (MIC; and assisted and unassisted peak cough flow (APCF and UPCF, respectively with insufflations. RESULTS: After the use of home air-stacking maneuvers, there were improvements in the APCF and UPCF. In the patients without scoliosis, there was also a significant increase in FVC. When comparing patients with and without scoliosis, the increases in APCF and UPCF were more pronounced in those without scoliosis. CONCLUSIONS: Routine daily air-stacking maneuvers with a manual resuscitator appear to increase UPCF and APCF in patients with NMD, especially in those without scoliosis.

    To investigate the therapeutic method and effectiveness of multiple sternocleidomastoid head amputation for adult congenital muscular torticollis. Between March 2009 and February 2011, 19 patients with congenital muscular torticollis were treated with multiple sternocleidomastoid head amputation. There were 13 males and 6 females, aged 16-32 years (mean, 23.5 years). The X-ray films showed that 12 cases were accompanied with some extent cervical lateral bending and wedge change. Ten patients were with ipsilateral facial bradygenesis. Four patients had received single sternocleidomastoid head amputation. All of the 19 patients were treated with multiple sternocleidomastoid head amputation, then plaster support and neck collar were used after operation for 3-6 months. The wounds of all the 19 patients healed primarily, without infection or hematoma. Sixteen patients were followed up 5 months to 2 years (mean, 8 months). The head and neck malformations were ameliorated significantly. The effectiveness was assessed 2 weeks later, in 7 patients without cervical vertebral malformation results were excellent; in 12 patients with cervical vertebral malformation, the results were excellent in 1 case, good in 7 cases, and fair in 4 cases. The length between mastoid process and sternoclavicular joints was elongated (1.88 +/- 0.30) cm significantly after operation in patients without cervical vertebral malformation (t = 6.24, P = 0.00), showing no significant difference when compared with normal value (t = 1.87, P = 0.11); the length was elongated (3.38 +/- 0.30) cm significantly (t = 11.37, P = 0.00) after operation in patients with cervical vertebral malformation, but it was significant shorter than normal value (t = 12.19, P = 0.00). Multiple sternocleidomastoid head amputation is a safe and effective method for adult congenital muscular torticollis, which can improve the neck rotation function.

Foi realizado estudo das características clínicas, laboratoriais e histopatológicas de 18 pacientes com DMC, relacionadas com o padrão de merosina encontrado na biópsia muscular. Estudo imuno-histoquímico demonstrou que 11 pacientes eram merosina-deficiente (MD e sete pacientes eram merosina-positiva (MP. Nenhum dos nove pacientes MD com idade suficiente para serem avaliados alcançaram a capacidade de deambulação, enquanto quatro dos sete pacientes MP atingiram deambulação sem auxílio. Os níveis de creatinoquinase estavam mais aumentados nos pacientes MD, mas a diferença entre os dois grupos não foi estatisticamente significativa. Estudo da condução nervosa motora foi realizado em 12 pacientes. Todos os quatro pacientes MP apresentaram exames normais, enquanto dois de oito pacientes MD apresentaram diminuição da velocidade de condução nervosa motora. Entre 69 parâmetros de biópsia muscular avaliados, não foi encontrada diferença estatisticamente significativa entre os grupos MP e MD. Esses resultados sugerem que a diferenciação entre os casos MP e MD serve para fins de prognóstico, pois os pacientes MP chegam a deambular. Além disso, este estudo indica que não existe relação entre a ausência de merosina e as alterações histológicas encontradas na biópsia muscular.Merosin α2 chain, an extracellular matrix protein, is deficient in a proportion of patients with classical congenital muscular dystrophy (CMD.

In one patient with partial merosin deficiency, MRI was normal. The other four patients had supratentorial white matter abnormalities. In three, T2-weighted images revealed subcortical, deep lobar and periventricular high signal in white matter, while in the other there were only small peritrigonal areas of increased signal. On T1-weighted images, there was slightly low signal. Cortical abnormalities were absent. None of these changes were accompanied by symptoms or signs of central nervous system involvement. White matter abnormalities in a patient with CMD should prompt investigation of merosin. (orig.) With 4 figs., 11 refs.

    Merosin-deficient congenital muscular dystrophy (CMD) is characterized clinically by hypotonia and muscular weakness and, on imaging studies, by white matter (WM) abnormality. To evaluate MRI findings in Brazilian patients with merosin-deficient CMD. Twenty-five patients were evaluated using MRI. Three patients presented with partial merosin deficiency and 22 with total merosin deficiency. Follow-up examinations were done in 7 cases. T1- and T2-weighted images were performed in all examinations, and fluid-attenuated inversion recovery (FLAIR) was performed in 15. Enhanced images were done in 11 cases. The WM involvement was classified according to location and severity. From 1991 to 2004, 32 MRI examinations were performed. Severe involvement was found in 23 patients in the frontal and temporal lobes, in 18 patients in the parietal lobes, and in 7 patients in the occipital lobes. The brain stem (n=5), cerebellum (n=6), internal capsules (n=1), and external capsules (n=5) were also affected. One patient had occipital pachygyria, and one had cerebellar vermian hypoplasia. No gadolinium enhancement was noted. Follow-up MRI showed no interval change (n=4), progression (n=1), or improvement of the findings (n=2). (orig.)

    This case series examined preoperative findings and the surgical, anesthetic, and postoperative management of 6 patients with congenital myopathies (CMs) and congenital muscular dystrophies (CMDs) treated at a tertiary medical institution with orthognathic surgery over 15 years to describe pertinent considerations for performing orthognathic surgery in these complex patients. According to the institutional review board-approved protocol, chart records were reviewed for all orthognathic surgical patients with a clinical, genetic, or muscle biopsy-proved diagnosis of CM or CMD. Six patients (5 male, 1 female) qualified, and they were treated by 4 surgeons in the division of oral and maxillofacial surgery from 1992 through 2007. Average age was 19.5 years at the time of orthognathic surgery. Five patients had Class III malocclusions and 1 patient had Class II malocclusion. All 6 patients had apertognathia with lip incompetence. Nasoendotracheal intubation with a difficulty of 0/3 (0=easiest, 3=most difficult) was performed in all cases. Routine induction and maintenance anesthetics, including halogenated agents and nondepolarizing muscle relaxants, were administered without malignant hyperthermia. All 6 patients underwent Le Fort level osteotomies; 4 also had mandibular setback surgery with or without balancing mandibular inferior border osteotomies. Five patients required planned intensive care unit care postoperatively (average, 18.4 days; range, 4 to 65 days). Postoperative respiratory complications resulting in major blood oxygen desaturations occurred in 5 patients; 4 of these patients required reintubation during emergency code response. Five patients required extended postoperative intubation (average, 4.2 days; range, 3 to 6 days) and ventilatory support. Average hospital length of stay was 21.8 days (range, 6 to 75 days). Average postoperative follow-up interval was 29.8 weeks (range, 6 to 128 weeks). Patients with CMs or CMDs often have characteristic

    Collagen VI mutations lead to disabling myopathies like Bethlem myopathy (BM) and Ullrich congenital muscular dystrophy (UCMD). We have investigated the nutritional and metabolic status of one UCMD and seven BM patients (five female, three male, mean age 31 ± 9 years) in order to find a potential metabolic target for nutritional intervention. For this study, we used standard anthropometric tools, such as BMI evaluation and body circumference measurements. All results were compared to dual-energy X-ray absorptiometry (DXA), considered the "gold standard" method. Energy intake of each patient was evaluated through longitudinal methods (7-day food diary) while resting energy expenditure (REE) was predicted using specific equations and measured by indirect calorimetry. Clinical evaluation included general and nutritional blood and urine laboratory analyses and quantitative muscle strength measurement by hand-held dynamometry. BM and UCMD patients showed an altered body composition, characterized by low free fat mass (FFM) and high fat mass (FM), allowing us to classify them as sarcopenic, and all but one as sarcopenic-obese. Another main result was the negative correlation between REE/FFM ratio (basal energy expenditure per kilograms of fat-free mass) and the severity of the disease, as defined by the muscle megascore (correlation coefficient -0.955, P-value nutritional intervention in these patients.

    Full Text Available Six individuals with Ullrich congenital muscular dystrophy (UCMD and mutations in the genes-encoding collagen VI, aging 5–9, received 3–5 mg/kg of cyclosporine A (CsA daily for 1 to 3.2 years. The primary outcome measure was the muscle strength evaluated with a myometer and expressed as megalimbs. The megalimbs score showed significant improvement (P=0.01 in 5 of the 6 patients. Motor function did not change. Respiratory function deteriorated in all. CsA treatment corrected mitochondrial dysfunction, increased muscle regeneration, and decreased the number of apoptotic nuclei. Results from this study demonstrate that long-term treatment with CsA ameliorates performance in the limbs, but not in the respiratory muscles of UCMD patients, and that it is well tolerated. These results suggest considering a trial of CsA or nonimmunosuppressive cyclosporins, that retains the PTP-desensitizing properties of CsA, as early as possible in UCMD patients when diaphragm is less compromised.

    Full Text Available The dystrophin distribution in the plasma muscle membrane using immunohystochemistry was studied in 22 children with congenital muscular dystrophy. The dystrophin was detected by immunofluorescence in muscle biopsy through a polyclonal antibody. All the cases had patchy interruptions of the fluorescence in the plasma membrane. A large patchy interruption of the sarcolemma was found in 17 cases, small interruption in 12, and a combination of large and small patchy discontinuity in 7. Small gaps around the fiber like a rosary were found in 15 cases. The frequency of these abnormalities ranged cases from: all fibers in 5 cases, frequent in 8, occasional in 5, and rare in 4. Five cases had total absence of immunofluorescence. These results suggest that the dystrophin expression is abnormal in this group of children and that this type of abnormalities can not be differentiated from early Becker muscular dystrophy nor childhood autosomal recessive muscular dystrophy through immunohystochemistry alone.Foi estudada a distribuição da distrofina na membrana plasmática das fibras musculares em 22 crianças com distrofia muscular congênita, através de técnicas de imuno-histoquímica. A distrofina foi identificada nas biópsias musculares processadas a fresco, por técnicas de imunofluorescência utilizando anticorpos policlonais. Todos os casos tinham interrupções da imunofluorescência na membrana plasmática. Em 17 elas eram grandes, em 12 eram pequenas e em 7 eram de ambos os tipos. Fibras com interrupções pequenas e constantes, como um rosário, foram vistas em 15 casos. Essas anormalidades estavam presentes em todas as fibras em 5 casos, eram frequentes em 8, ocasionais em 5 e raras em 4. Cinco casos mostraram fibras sem distrofina. Esses dados sugerem que a expressão da distrofina é anormal nesse grupo de crianças. Essas anormalidades podem também ser encontradas em casos precoces de distrofia muscular de Becker e distrofia autoss

    Full Text Available O artigo contrasta as teses de Huntington e Fukuyama sobre desenvolvimento político. As obras analisadas, Ordem política nas sociedades em mudança e O fim da história, inscrevem-se entre duas conjunturas decisivas - 1968 e 1989. Huntington desmontou a equivalência entre desenvolvimento político e modernização e Fukuyama reafirmou a democracia como o destino de todos os países e, desse modo, como o fim da história. Nesta comparação, dois eixos se sobressaem: o contexto de produção das obras e a alternância entre os polos teóricos da democracia e da estabilidade. Procura-se demonstrar como, apesar de reinserir a democracia no desenvolvimento político, a instabilidade continua a ser um foco privilegiado de análise no pensamento de Fukuyama.The article contrasts the theories of Huntington and Fukuyama on political development. The analyzed works, Political order in changing societies and The end of history, fall between two decisive historical moments - in 1968 and 1989. Huntington disassembled the equivalence between political development and modernization; Fukuyama reaffirmed democracy as the destiny of all countries and, as such, it is the end of history. In this comparison, two axes call our attention: the production context of these works and the alternation between the theoreticals poles of democracy and stability. The article shows how, although reenters democracy in the political development theory, instablility remains a prime focus of analysis in Fukuyama's thought.

    The American Physical Therapy Association (APTA) published a guideline for congenital muscular torticollis (CMT) in 2013. Our division adopted the guideline as the institutional practice standard and engaged in a quality improvement (QI) initiative to increase the percentage of patients who achieved resolution of CMT within 6 months of evaluation. The aims of this report are to describe the QI activities conducted to improve patient outcomes and discuss the results and implications for other institutions and patient populations. This was a quality improvement study. In alignment with the Chronic Care Model and Model of Improvement, an aim and operationally defined key outcome and process measures were established. Interventions were tested using Plan-Do-Study-Act cycles. A CMT registry was established to store and manage data extracted from the electronic record over the course of testing. Statistical process control charts were used to monitor progress over time. The QI initiative resulted in an increase in the percentage of patients who achieved full resolution of CMT within a 6-month episode of care from 42% to 61% over an 18-month period. Themes that emerged as key drivers of improvement included: (1) timely, optimal access to care, (2) effective audit and clinician feedback, and (3) accurate, timely documentation. The initiative took place at a single institution with a supportive culture and strong QI resources, which may limit direct translation of interventions and findings to other institutions and patient populations. Improvement science methodologies provided the tools and structure to improve division-wide workflow and increase consistency in the implementation of the APTA CMT guideline. In doing so, significant CMT population outcome improvements were achieved. © 2017 American Physical Therapy Association

    Full Text Available Collagen VI related myopathies encompass a range of phenotypes with involvement of skeletal muscle, skin and other connective tissues. They represent a severe and relatively common form of congenital disease for which there is no treatment. Collagen VI in skeletal muscle and skin is produced by fibroblasts.In order to gain insight into the consequences of collagen VI mutations and identify key disease pathways we performed global gene expression analysis of dermal fibroblasts from patients with Ullrich Congenital Muscular Dystrophy with and without vitamin C treatment. The expression data were integrated using a range of systems biology tools. Results were validated by real-time PCR, western blotting and functional assays.We found significant changes in the expression levels of almost 600 genes between collagen VI deficient and control fibroblasts. Highly regulated genes included extracellular matrix components and surface receptors, including integrins, indicating a shift in the interaction between the cell and its environment. This was accompanied by a significant increase in fibroblasts adhesion to laminin. The observed changes in gene expression profiling may be under the control of two miRNAs, miR-30c and miR-181a, which we found elevated in tissue and serum from patients and which could represent novel biomarkers for muscular dystrophy. Finally, the response to vitamin C of collagen VI mutated fibroblasts significantly differed from healthy fibroblasts. Vitamin C treatment was able to revert the expression of some key genes to levels found in control cells raising the possibility of a beneficial effect of vitamin C as a modulator of some of the pathological aspects of collagen VI related diseases.

    Full Text Available Congenital muscular dystrophy is a distinct group of diseases presenting with weakness in infancy or childhood and no current therapy. One form, MDC1A, is the result of laminin alpha-2 deficiency and results in significant weakness, respiratory insufficiency and early death. Modification of apoptosis is one potential pathway for therapy in these patients.dy(2J mice were treated with vehicle, 0.1 mg/kg or 1 mg/kg of omigapil daily via oral gavage over 17.5 weeks. Untreated age matched BL6 mice were used as controls. Functional, behavioral and histological measurements were collected.dy(2J mice treated with omigapil showed improved respiratory rates compared to vehicle treated dy(2J mice (396 to 402 vs. 371 breaths per minute, p<0.03 and similar to control mice. There were no statistical differences in normalized forelimb grip strength between dy(2J and controls at baseline or after 17.5 weeks and no significant differences seen among the dy(2J treatment groups. At 30-33 weeks of age, dy(2J mice treated with 0.1 mg/kg omigapil showed significantly more movement time and less rest time compared to vehicle treated. dy(2J mice showed normal cardiac systolic function throughout the trial. dy(2J mice had significantly lower hindlimb maximal (p<0.001 and specific force (p<0.002 compared to the control group at the end of the trial. There were no statistically significant differences in maximal or specific force among treatments. dy(2J mice treated with 0.1 mg/kg/day omigapil showed decreased percent fibrosis in both gastrocnemius (p<0.03 and diaphragm (p<0.001 compared to vehicle, and in diaphragm (p<0.013 when compared to 1 mg/kg/day omigapil treated mice. Omigapil treated dy(2J mice demonstrated decreased apoptosis.Omigapil therapy (0.1 mg/kg improved respiratory rate and decreased skeletal and respiratory muscle fibrosis in dy(2J mice. These results support a putative role for the use of omigapil in laminin deficient congenital muscular dystrophy

  14. Melanocytes from patients affected by Ullrich congenital muscular dystrophy and Bethlem myopathy have dysfunctional mitochondria that can be rescued with cyclophilin inhibitors

    2014-11-01

    Full Text Available Ullrich congenital muscular dystrophy and Bethlem myopathy are caused by mutations in collagen VI genes, which encode an extracellular matrix protein; yet mitochondria play a major role in disease pathogenesis through a short circuit caused by inappropriate opening of the permeability transition pore, a high conductance channel which causes a shortage in ATP production. We find that melanocytes do not produce collagen VI yet they bind it at the cell surface, suggesting that this protein may play a trophic role and that its absence may cause lesions similar to those seen in skeletal muscle. We show that mitochondria in melanocytes of Ullrich congenital muscular dystrophy and Bethlem myooathy patients display increased size, reduced matrix density and disrupted cristae, findings that suggest a functional impairment. In keeping with this hypothesis, mitochondria (i underwent anomalous depolarization after inhibition of the F-ATP synthase with oligomycin, and (ii displayed decreased respiratory reserve capacity. The non-immunosuppressive cyclophilin inhibitor NIM811 prevented mitochondrial depolarization in response to oligomycin in melanocytes from both Ullrich congenital muscular dystrophy and Bethlem myopathy patients, and partially restored the respiratory reserve of melanocytes from one Bethlem myopathy patient. These results match our recent findings on melanocytes from patients affected by Duchenne muscular dystrophy (Pellegrini et al., 2013 Melanocytes--a novel tool to study mitochondrial dysfunction in Duchenne muscular dystrophy. J Cell Physiol 228, 1323-1331, and suggest that skin biopsies may represent a minimally invasive tool to investigate mitochondrial dysfunction and to evaluate drug efficacy in collagen VI-related myopathies and possibly in other muscle wasting conditions like aging sarcopenia.

    2014-01-01

    Full Text Available Ullrich congenital muscular dystrophy (UCMD is an inherited muscle disorder characterized clinically by muscle weakness, distal joint hyperlaxity, and proximal joint contractures. Sporadic and recessive mutations in the three collagen VI genes, COL6A1, COL6A2, and COL6A3, are reported to be causative. In the sporadic forms, a heterozygous point mutation causing glycine substitution in the triple helical domain has been identified in higher rate. In this study, we examined the efficacy of siRNAs, which target point mutation site, on specific knockdown toward transcripts from mutant allele and evaluated consequent cellular phenotype of UCMD fibroblasts. We evaluated the effect of siRNAs targeted to silence-specific COL6A1 alleles in UCMD fibroblasts, where simultaneous expression of both wild-type and mutant collagen VI resulted in defective collagen localization. Addition of mutant-specific siRNAs allowed normal extracellular localization of collagen VI surrounding fibroblasts, suggesting selective inhibition of mutant collagen VI. Targeting the single-nucleotide COL6A1 c.850G>A (p.G284R mutation responsible a sporadic autosomal dominant form of UCMD can potently and selectively block expression of mutant collagen VI. These results suggest that allele-specific knockdown of the mutant mRNA can potentially be considered as a therapeutic procedure in UCMD due to COL6A1 point mutations.

    Full Text Available Specific mutations in LMNA, which encodes nuclear intermediate filament proteins lamins A/C, affect skeletal muscle tissues. Early-onset LMNA myopathies reveal different alterations of muscle fibers, including fiber type disproportion or prominent dystrophic and/or inflammatory changes. Recently, we identified the p.R388P LMNA mutation as responsible for congenital muscular dystrophy (L-CMD and lipodystrophy. Here, we asked whether viral-mediated expression of mutant lamin A in murine skeletal muscles would be a pertinent model to reveal specific muscle alterations. We found that the total amount and size of muscle fibers as well as the extent of either inflammation or muscle regeneration were similar to wildtype or mutant lamin A. In contrast, the amount of fast oxidative muscle fibers containing myosin heavy chain IIA was lower upon expression of mutant lamin A, in correlation with lower expression of genes encoding transcription factors MEF2C and MyoD. These data validate this in vivo model for highlighting distinct muscle phenotypes associated with different lamin contexts. Additionally, the data suggest that alteration of muscle fiber type identity may contribute to the mechanisms underlying physiopathology of L-CMD related to R388P mutant lamin A.

    Congenital muscle hypertrophy of the upper limb is a very rare condition with unknown aetiology. This descriptive observational and retrospective series included eight children followed by a multidisciplinary team from 2005 to 2017. The diagnosis was based on a cluster of clinical and radiological characteristics after elimination of differential diagnoses. Patients were categorized according to: anomalies of the wrist, anomalies of long fingers of intrinsic or extrinsic origin; and anomalies of the thumb with or without first web space contracture. Treatment begins in young children with hand orthoses to limit muscle contraction and joint malposition. The purpose of surgical treatment was to release contractures and to restore muscle balance through, in the main, finger intrinsic releases and first web releases. At the 2-year follow-up, we found that limited surgical procedures improved finger, thumb and wrist positions. We conclude that muscle hypertrophy is the main cause of deformity and that selective releases of contracted musculo-tendinous units and skin lengthening are effective. IV.

A forma de Ullrich é caracterizada por retrações musculares proximais e hiperextensibilidade distal. Cerca de 40% destes pacientes apresentam mutações em um dos genes que codificam as três sub-unidades do colágeno VI (COL6, acarretando deficiência total ou parcial na marcação da proteína. Analisamos, através de imunofluorescência, a marcação do COL6 em fragmentos musculares de 50 pacientes com DMC, 20 deles com ausência da marcação para merosina. Identificamos 4 casos com deficiência total da marcação do COL6 (8% do total, representando 13% dos casos com marcação normal para merosina. As alterações histológicas musculares dos pacientes com COL6 deficiente eram indistinguíveis das outras formas de DMC, porém mais brandas que as observadas na DMC com deficiência de merosina. Em três dos pacientes com COL6 deficiente observou-se hipotonia e fraqueza muscular, notadas já no período neonatal, atraso do desenvolvimento motor, retrações musculares em joelhos e cotovelos, hiperextensibilidade distal e luxação congênita do quadril (dois pacientes.

    Infants grow rapidly, which causes the SCM to thicken physiologically. Therefore some cases of physiologically-thickened SCM can be confused with a poor response to physical therapy. There have been only a few quantitative ultrasonographic studies on the clinical outcome of rehabilitation for CMT. Our aim was to evaluate whether a new sonographic assessment method that uses the muscular thickness ratio of the SCM can help quantify the outcome of rehabilitation therapy for patients with CMT. We evaluated 48 patients (male/female, 17:31; mean age, 3.9 months) who were diagnosed with CMT and who underwent initial and follow-up sonography. The ratio of the thickness of the involved SCM to the thickness of the intact SCM (SCM thickness ratio) was calculated. A scoring system based on the range of motion of the neck was used to assess clinical improvement. The correlations between clinical improvement and the thickness of the involved muscle, the difference in involved muscle thickness, the SCM thickness ratio, and the difference in the SCM thickness ratio were evaluated with Spearman rank correlations. Follow-up Cheng scores were higher than initial scores; this difference indicates clinical resolution (follow-up, 4.90; initial, 3.38). The SCM thickness ratio at follow-up was lower than that at the initial evaluation (follow-up, 1.29-1.34; initial, 1.65-1.77). Intra- and interobserver agreements were excellent. Most variables were moderately correlated with clinical improvement (correlation coefficients, 0.36-0.509). R1 showed the highest correlation with clinical improvement (0.481 and 0.509), followed by the initial maximal thickness of the SCM (0.434 and 0.488). ΔP (P1-P2) and ΔR showed similar correlation coefficients with clinical improvement. Measurement of the SCM thickness ratio appears to overcome the problem of a false-positive diagnosis of clinical aggravation of CMT resulting from physiologic growth. R1 and ΔR are accurate objective measurements, which

    To compare clinical findings for patients with congenital muscular torticollis (CMT) between those with and without a sternocleidomastoid (SCM) lesion. Medical records of 182 patients with CMT were retrospectively reviewed and the patients were divided into SCM lesion and nonlesion groups by ultrasonographic results. Intrauterine position, age, duration of therapy, rotation/tilting side, and the passive range of motion and angle of the neck were compared. There were 74 SCM lesion and 108 nonlesion cases. The mean age at the first visit was 55.3 days in the SCM lesion group and 146.6 days in the nonlesion group. The mean therapy time in the nonlesion group was 66.5 days, significantly shorter than for the SCM lesion group (117.5 d). Tilting and rotation of the head in the same direction was observed only in the nonlesion group (n=9, 8.3%). Rotational limitation of the affected muscle side was 22.6 degree in the SCM lesion and 3.6 degree in the nonlesion group, and the tilting limitation was 19.2 degree in the SCM lesion and 10.4 degree in the nonlesion group. The nonlesion group had a better prognosis with shorter treatment duration. This group was more limited in head tilting than in head rotation, and the pattern of head rotation/tilting in the same direction was observed only in this group. These findings suggest that pathophysiological mechanisms and clinical characteristics may differ between CMT patients with and without SCM lesions. Level II-prognostic studies, retrospective study.

    A Congenital Muscular Dystrophy (CMD) Working Group (WG) consisting of international experts reviewed common data elements (CDEs) previously developed for other neuromuscular diseases (NMDs) and made recommendations for all types of studies on CMD. To develop a comprehensive set of CDEs, data definitions, case report forms and guidelines for use in CMD clinical research to facilitate interoperability of data collection, as part of the CDE project at the National Institute of Neurological Disorders and Stroke (NINDS). One working group composed of ten experts reviewed existing NINDS CDEs and outcome measures, evaluated the need for new elements, and provided recommendations for CMD clinical research. The recommendations were compiled, internally reviewed by the CMD working group, and posted online for external public comment. The CMD working group and the NIH CDE team reviewed the final version before release. The NINDS CMD CDEs and supporting documents are publicly available on the NINDS CDE website (https://www.commondataelements.ninds.nih.gov/CMD.aspx#tab=Data_Standards). Content areas include demographics, social status, health history, physical examination, diagnostic tests, and guidelines for a variety of specific outcomes and endpoints. The CMD CDE WG selected these documents from existing versions that were generated by other disease area working groups. Some documents were tailored to maximize their suitability for the CMD field. Widespread use of CDEs can facilitate CMD clinical research and trial design, data sharing and retrospective analyses. The CDEs that are most relevant to CMD research are like those generated for other NMDs, and CDE documents tailored to CMD are now available to the public. The existence of a single source for these documents facilitates their use in research studies and offers a clear mechanism for the discussion and update of the information as knowledge is gained.

Since 1806 year there is no essential political progress, according to Fukuyama, abroad principles of French bourgeois revolution there is no advance. History which appears to be progressive and directional, suggest Fukuyama, ends right there. Word is divided into historical and post historical, social balance of the first one depend of the social misbalance of the second.

    The integrins are a large family of heterodimeric transmembrane cellular receptors which mediate the association between the extracellular matrix (ECM) and cytoskeletal proteins. The alpha7beta1 integrin is a major laminin binding integrin in skeletal and cardiac muscle and is thought to be involved in myogenic differentiation and migration processes. The main binding partners of the alpha7 integrin are laminin-1 (alpha1-beta1-gamma1), laminin-2 (alpha2-beta1-gamma1) and laminin-4 (alpha2-beta2-gamma1). Targeted deletion of the gene for the alpha7 integrin subunit (ITGA7) in mice leads to a novel form of muscular dystrophy. In the present study we have investigated the expression of two alternative splice variants, the alpha7B and beta1D integrin subunits, in normal human skeletal muscle, as well as in various forms of muscular dystrophy. In normal human skeletal muscle the expression of the alpha7 integrin subunit appeared to be developmentally regulated: it was first detected at 2 years of age. In contrast, the beta1D integrin could be detected in immature and mature muscle in the sarcolemma of normal fetal skeletal muscle at 18 weeks gestation. The expression of alpha7B integrin was significantly reduced at the sarcolemma in six patients with laminin alpha2 chain deficient congenital muscular dystrophy (CMD) (age >2 years). However, this reduction was not correlated with the amount of laminin alpha2 chain expressed. In contrast, the expression of the laminin alpha2 chain was not altered in the skeletal muscle of the alpha7 knock-out mice. These data argue in favor that there is not a tight correlation between the expression of the alpha7 integrin subunit and that of the laminin alpha2 chain in either human or murine dystrophic muscle. Interestingly, in dystrophinopathies (Duchenne and Becker muscular dystrophy; DMD/BMD) expression of alpha7B was upregulated irrespective of the level of dystrophin expression as shown by a strong sarcolemmal staining pattern even

    Merosin-deficient congenital muscular dystrophy type 1A (MDC1A) is a lethal muscle-wasting disease that is caused by mutations in the LAMA2 gene, resulting in the loss of laminin-α2 protein. MDC1A patients exhibit severe muscle weakness from birth, are confined to a wheelchair, require ventilator assistance, and have reduced life expectancy. There are currently no effective treatments or cures for MDC1A. Laminin-α2 is required for the formation of heterotrimeric laminin-211 (ie, α2, β1, and γ1) and laminin-221 (ie, α2, β2, and γ1), which are major constituents of skeletal muscle basal lamina. Laminin-111 (ie, α1, β1, and γ1) is the predominant laminin isoform in embryonic skeletal muscle and supports normal skeletal muscle development in laminin-α2-deficient muscle but is absent from adult skeletal muscle. In this study, we determined whether treatment with Engelbreth-Holm-Swarm-derived mouse laminin-111 protein could rescue MDC1A in the dy(W-/-) mouse model. We demonstrate that laminin-111 protein systemically delivered to the muscles of laminin-α2-deficient mice prevents muscle pathology, improves muscle strength, and dramatically increases life expectancy. Laminin-111 also prevented apoptosis in laminin-α2-deficient mouse muscle and primary human MDC1A myogenic cells, which indicates a conserved mechanism of action and cross-reactivity between species. Our results demonstrate that laminin-111 can serve as an effective protein substitution therapy for the treatment of muscular dystrophy in the dy(W-/-) mouse model and establish the potential for its use in the treatment of MDC1A.

    Transcriptional signal cointegrators associate with transcription factors or nuclear receptors and coregulate tissue-specific gene transcription. We report on recessive loss-of-function mutations in two genes (TRIP4 and ASCC1) that encode subunits of the nuclear activating signal cointegrator 1 (ASC-1) complex. We used autozygosity mapping and whole-exome sequencing to search for pathogenic mutations in four families. Affected individuals presented with prenatal-onset spinal muscular atrophy (SMA), multiple congenital contractures (arthrogryposis multiplex congenita), respiratory distress, and congenital bone fractures. We identified homozygous and compound-heterozygous nonsense and frameshift TRIP4 and ASCC1 mutations that led to a truncation or the entire absence of the respective proteins and cosegregated with the disease phenotype. Trip4 and Ascc1 have identical expression patterns in 17.5-day-old mouse embryos with high expression levels in the spinal cord, brain, paraspinal ganglia, thyroid, and submandibular glands. Antisense morpholino-mediated knockdown of either trip4 or ascc1 in zebrafish disrupted the highly patterned and coordinated process of α-motoneuron outgrowth and formation of myotomes and neuromuscular junctions and led to a swimming defect in the larvae. Immunoprecipitation of the ASC-1 complex consistently copurified cysteine and glycine rich protein 1 (CSRP1), a transcriptional cofactor, which is known to be involved in spinal cord regeneration upon injury in adult zebrafish. ASCC1 mutant fibroblasts downregulated genes associated with neurogenesis, neuronal migration, and pathfinding (SERPINF1, DAB1, SEMA3D, SEMA3A), as well as with bone development (TNFRSF11B, RASSF2, STC1). Our findings indicate that the dysfunction of a transcriptional coactivator complex can result in a clinical syndrome affecting the neuromuscular system. PMID:26924529

DyW mice also have significantly elevated muscle levels (suggestive of inflammation and edema. Muscle T2 returned to WT levels in response to Losartan treatment. When considering only muscle pixels without T2 elevation, DyW T2 levels are significantly lower than WT (suggestive of fibrosis whereas Losartan-treated animals do not demonstrate this decrease in muscle T2. MRI measurements suggestive of elevated inflammation and fibrosis corroborate with increased Mac-1 positive cells as well as increased Picrosirius red staining/COL1a gene expression that is returned to WT levels in response to Losartan.MRI is sensitive to and tightly corresponds with pathological changes in DyW mice and thus is a viable and effective non-invasive tool for assessing pathological changes.

    Merosin-deficient congenital muscular dystrophy type 1A (MDC1A) is a dramatic neuromuscular disease in which crippling muscle weakness is evident from birth. Here, we use the dyW mouse model for human MDC1A to trace the onset of the disease during development in utero. We find that myotomal and primary myogenesis proceed normally in homozygous dyW-/- embryos. Fetal dyW-/- muscles display the same number of myofibers as wildtype (WT) muscles, but by E18.5 dyW-/- muscles are significantly smaller and muscle size is not recovered post-natally. These results suggest that fetal dyW-/- myofibers fail to grow at the same rate as WT myofibers. Consistent with this hypothesis between E17.5 and E18.5 dyW-/- muscles display a dramatic drop in the number of Pax7- and myogenin-positive cells relative to WT muscles, suggesting that dyW-/- muscles fail to generate enough muscle cells to sustain fetal myofiber growth. Gene expression analysis of dyW-/- E17.5 muscles identified a significant increase in the expression of the JAK-STAT target gene Pim1 and muscles from 2-day and 3-week old dyW-/- mice demonstrate a dramatic increase in pSTAT3 relative to WT muscles. Interestingly, myotubes lacking integrin α7β1, a laminin-receptor, also show a significant increase in pSTAT3 levels compared with WT myotubes, indicating that α7β1 can act as a negative regulator of STAT3 activity. Our data reveal for the first time that dyW-/- mice exhibit a myogenesis defect already in utero. We propose that overactivation of JAK-STAT signaling is part of the mechanism underlying disease onset and progression in dyW-/- mice. © The Author 2017. Published by Oxford University Press.

    To delineate optimal diagnostic and therapeutic approaches to congenital muscular dystrophy (CMD) through a systematic review and analysis of the currently available literature. Relevant, peer-reviewed research articles were identified using a literature search of the MEDLINE, EMBASE, and Scopus databases. Diagnostic and therapeutic data from these articles were extracted and analyzed in accordance with the American Academy of Neurology classification of evidence schemes for diagnostic, prognostic, and therapeutic studies. Recommendations were linked to the strength of the evidence, other related literature, and general principles of care. The geographic and ethnic backgrounds, clinical features, brain imaging studies, muscle imaging studies, and muscle biopsies of children with suspected CMD help predict subtype-specific diagnoses. Genetic testing can confirm some subtype-specific diagnoses, but not all causative genes for CMD have been described. Seizures and respiratory complications occur in specific subtypes. There is insufficient evidence to determine the efficacy of various treatment interventions to optimize respiratory, orthopedic, and nutritional outcomes, and more data are needed regarding complications. Multidisciplinary care by experienced teams is important for diagnosing and promoting the health of children with CMD. Accurate assessment of clinical presentations and genetic data will help in identifying the correct subtype-specific diagnosis in many cases. Multiorgan system complications occur frequently; surveillance and prompt interventions are likely to be beneficial for affected children. More research is needed to fill gaps in knowledge regarding this category of muscular dystrophies. © 2015 American Academy of Neurology.

    A 3-year-old, male Labrador retriever dog was presented with clinical signs of progressive exercise intolerance, bilateral elbow extension, rigidity of the forelimbs, hindlimb flexion and kyphosis. Microscopical examination of muscle tissue showed marked variability in myofibre size, replacement of muscle with mature adipose tissue and degeneration/regeneration of muscle fibres, consistent with muscular dystrophy. Immunohistochemical examination for dystrophin showed markedly reduced labelling with monoclonal antibodies specific for the rod domain and the carboxy-terminal of dystrophin, while expression of β-sarcoglycan, γ-sarcoglycan and β-dystroglycan was normal. Immunoblotting revealed a truncated dystrophin protein of approximately 135 kDa.

  5. Microbiological and biochemical survey on the transition of fermentative processes in Fukuyama pot vinegar brewing.

    Traditional brewing of Fukuyama pot vinegar is a process that has been continued in Fukuyama, Kagoshima, Japan, for almost 200 years. The entire process proceeds from raw materials, including steamed rice, rice koji (steamed rice grown with a fungus, Aspergillus oryzae) and water, to produce vinegar in roughly capped large pots laid in the open air. No special fermentative manipulation is required, except for scattering dried rice koji (called furi-koji) on the surface of the mash to form a cap-like mat on the surface at the start of brewing. As the biochemical mechanism of the natural transition of the fermentative processes during brewing has not been fully explained, we conducted a microbiological and biochemical study on the transition. First, a distinct biochemical change was observed in the brewing of spring preparation; that is, a sharp decline in pH from 6.5 to 3.5 within the first 5 days of brewing was observed due to lactic acid fermentation. Alcoholic fermentation also proceeded with a sharp increase to 4.5% ethanol within the first 5 days under the acidic conditions, suggesting that saccharification and both fermentations proceed in parallel. Acidic conditions and ethanol accumulation restricted the growth of most microorganisms in the mash, and in turn provided a favorable growth condition for acetic acid bacteria which are acid resistant and "ethanol-philic." Acetic acid was detected from day 16 and gradually increased in concentration, reaching a maximum of 7% at day 70 that was maintained thereafter. Empirically furi-koji naturally sinks into the mash after around day 40 by an unknown mechanism, allowing acetic acid bacteria to easily form pellicles on the mash surface and promoting efficient acetic acid fermentation. Dominant microbial species involved in the three fermentations were identified by denaturing gradient gel electrophoresis analysis using PCR-amplified defined-regions of small rDNA from microorganisms in the brewing mash or colony

    With the aid of the symbolic computation, we present an improved ( G ‧ / G ) -expansion method, which can be applied to seek more types of exact solutions for certain nonlinear evolution equations. In illustration, we choose the (3 + 1)-dimensional potential Yu-Toda-Sasa-Fukuyama equation to demonstrate the validity and advantages of the method. As a result, abundant explicit and exact nontraveling wave solutions are obtained including two solitary waves solutions, nontraveling wave solutions and dromion soliton solutions. Some particular localized excitations and the interactions between two solitary waves are researched. The method can be also applied to other nonlinear partial differential equations.

    Rhabdomyolysis is a potentially life threatening condition of various etiology. The association between rhabdomyolysis and muscular dystrophies is under-recognized in clinical practice. To identify muscular dystrophies presenting with rhabdomyolysis at onset or as predominant feature. We retrospectively reviewed clinical and laboratory data of patients with a genetically confirmed muscular dystrophy in whom rhabdomyolysis was the presenting or main clinical manifestation. Thirteen unrelated patients (males=6; females=7) were identified. Median age at time of rhabdomyolysis was 18 years (range, 2-47) and median duration between the first episode of rhabdomyolysis and molecular diagnosis was 2 years. Fukutin-related protein (FKRP) muscular dystrophy (n=6) was the most common diagnosis, followed by anoctaminopathy-5 (n=3), calpainopathy-3 (n=2) and dystrophinopathy (n=2). Four patients experienced recurrent rhabdomyolysis. Eight patients were asymptomatic and 3 reported myalgia and exercise intolerance prior to the rhabdomyolysis. Exercise (n=6) and fever (n=4) were common triggers; rhabdomyolysis was unprovoked in 3 patients. Twelve patients required hospitalization. Baseline CK levels were elevated in all patients (median 1200 IU/L; range, 600-3600). Muscular dystrophies can present with rhabdomyolysis; FKRP mutations are particularly frequent in causing such complication. A persistently elevated CK level in patients with rhabdomyolysis warrants consideration for underlying muscular dystrophy. Copyright © 2015 Elsevier B.V. All rights reserved.

  20. Characteristic of muscle involvement evaluated by CT scans in early stages of progressive muscular dystrophy

    1993-01-01

    Muscle CT scans were performed in order to compare the characteristic distribution of progressive muscle involvement in the early stages of Duchenne type (DMD) and Fukuyama type muscular dystrophy (FCMD). Muscle images at the levels of the 3rd lumbar vertebra, thigh and calf were assessed by visual inspection, and mean CT numbers calculated for individual muscles were statistically analysed. On visual inspection, intramuscular low density areas and muscular atrophy were observed in the muscles of older patients with either disease. These changes were, however, more extensive at thigh level in DMD, and at calf level in FCMD. Nevertheless, the mean CT numbers of muscles in which only slight changes were grossly visible on CT scans displayed progressive decreases with increasing age. Moreover, a significant negative relationship was recognizable between age and mean CT number in almost all muscles examined. Comparison of the slopes of the regression lines revealed that the so-called selective pattern of muscle involvement characteristic of the symptomatic stage had already partially manifested in the preclinical or early stages of both diseases. In FCMD, the rates of decrease in CT numbers were extremely rapid for calf muscles as compared with those in DMD, indicating that this is one reason for FCMD patients never becoming ambulatory. However, for almost all of the other muscles, the CT numbers in FCMD decreased in parallel with the corresponding CT numbers in DMD; thus, these diseases displayed a similarity in the pattern of muscle involvement, despite their different pathogenetic mechanisms and inheritance patterns.

    Congenital muscular dystrophy, caused by mutations in LAMA2 (the gene encoding laminin α2 chain), is a severe and incapacitating disease for which no therapy is yet available. We have recently demonstrated that proteasome activity is increased in laminin α2 chain-deficient muscle and that treatment with the nonpharmaceutical proteasome inhibitor MG-132 reduces muscle pathology in laminin α2 chain-deficient dy(3K)/dy(3K) mice. Here, we explore the use of the selective and therapeutic proteasome inhibitor bortezomib (currently used for treatment of relapsed multiple myeloma and mantle cell lymphoma) in dy(3K)/dy(3K) mice and in congenital muscular dystrophy type 1A muscle cells. Outcome measures included quantitative muscle morphology, gene and miRNA expression analyses, proteasome activity, motor activity, and survival. Bortezomib improved several histological hallmarks of disease, partially normalized miRNA expression (miR-1 and miR-133a), and enhanced body weight, locomotion, and survival of dy(3K)/dy(3K) mice. In addition, bortezomib reduced proteasome activity in congenital muscular dystrophy type 1A myoblasts and myotubes. These findings provide evidence that the proteasome inhibitor bortezomib partially reduces laminin α2 chain-deficient muscular dystrophy. Investigation of the clinical efficacy of bortezomib administration in congenital muscular dystrophy type 1A clinical trials may be warranted.

    Full Text Available Preocupações mórbidas com a imagem corporal eram tidas até recentemente como problemas eminentemente femininos. Atualmente estas preocupações também têm sido encontradas no sexo masculino. A dismorfia muscular é um subtipo do transtorno dismórfico corporal que ocorre principalmente em homens que, apesar da grande hipertrofia muscular, consideram-se pequenos e fracos. Além de estar associada a prejuízos sociais, ocupacionais, recreativos e em outras áreas do funcionamento do indivíduo, a dismorfia muscular é também um fator de risco para o abuso de esteróides anabolizantes. Este artigo aborda aspectos epidemiológicos, etiológicos e padrões clínicos da dismorfia muscular, além de tecer comentários sobre estratégias de tratamento para este transtorno.Morbid concern over body image was considered, until recently, a female issue. Nowadays, it has been viewed as a common male disorder. Muscle dysmorphia, a subtype of a body dysmorphic disorder, affects men who, despite having clear muscular hypertroph,y see themselves as frail and small. Besides being associated to major social, leisure and occupational dysfunction, muscle dysmorphia is also a risk factor for the abuse of steroids. This article describes epidemiological, etiological and clinical characteristics of muscle dysmorphia and comments on its treatment strategy.

    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.

    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.

    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.

    1989-01-01

    By means of magnetic resonance imaging (MRI), the proton spin-lattice relaxation times (T1 values) of the skeletal muscles were measured in Duchenne muscular dystrophy (DMD) carriers and normal controls. The bound water fraction (BWF) was calculated from the T1 values obtained, according to the fast proton diffusion model. In the DMD carriers, T1 values of the gluteus maximus and quadriceps femoris muscles were significantly higher, and BWFs of these muscles were significantly lower than in normal control. Degenerative muscular changes accompanied by interstitial edema were presumed responsible for this abnormality. No correlation was observed between the muscle T1 and serum creatine kinase values. The present study showed that MRI could be a useful method for studying the dynamic state of water in both normal and pathological skeletal muscles. Its possible utility for DMD carrier detection was discussed briefly. (orig.)

    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%)

    Management for CMT starts during the early infancy and physiotherapy is the main treatment for this condition. But some of these CMT children may need surgical intervention to prevent further deterioration of cranial deformity and facial asymmetry. If these children are neglected and present later in life, they will have severe facial deformity with its associated sequelae. These patients are usually managed by other specialities worldwide. But awareness of these conditions is required among paediatric surgeons, as some of these children may be referred to them for treatment. In our case report we have also described various other modalities of treatment for this condition.

    2013-01-01

    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.

    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.

    2014-01-01

    The muscular dystrophies have been traditionally classified based mainly on clinical manifestation and mode of inheritance. Owing to the discoveries of causative genes, new terminologies derived from each gene, such as dystrophinopathy, α-dystroglycanopathy, sarcoglycanopathy and fukutinopathy, have also become common. Mutations of each gene may cause several clinical phenotypes. Some muscular dystrophies accompany central nervous system (CNS) lesions, especially in the congenital muscular dystrophies. Cobblestone lissencephaly (type II lissencephaly) is a well-known CNS malformation observed in severe forms of α-dystroglycanopathy. Moreover, CNS involvement has been reported in other muscular dystrophies, such as Duchenne muscular dystrophy. In this review, genes related to the muscular dystrophies associated with CNS lesions are briefly described along with the molecular characteristics of each gene and the pathomechanism of the CNS lesions. Understanding of both the clinicopathological characteristics of these CNS lesions and their molecular mechanisms is important for the diagnosis, care of patients, and development of new therapeutic strategies.

  18. A splice site mutation in laminin-α2 results in a severe muscular dystrophy and growth abnormalities in zebrafish.

    Directory of Open Access Journals (Sweden)

    Vandana A Gupta

    Full Text Available Congenital muscular dystrophy (CMD is a clinically and genetically heterogeneous group of inherited muscle disorders. In patients, muscle weakness is usually present at or shortly after birth and is progressive in nature. Merosin deficient congenital muscular dystrophy (MDC1A is a form of CMD caused by a defect in the laminin-α2 gene (LAMA2. Laminin-α2 is an extracellular matrix protein that interacts with the dystrophin-dystroglycan (DGC complex in membranes providing stability to muscle fibers. In an N-ethyl-N-nitrosourea mutagenesis screen to develop zebrafish models of neuromuscular diseases, we identified a mutant fish that exhibits severe muscular dystrophy early in development. Genetic mapping identified a splice site mutation in the lama2 gene. This splice site is highly conserved in humans and this mutation results in mis-splicing of RNA and a loss of protein function. Homozygous lama2 mutant zebrafish, designated lama2(cl501/cl501, exhibited reduced motor function and progressive degeneration of skeletal muscles and died at 8-15 days post fertilization. The skeletal muscles exhibited damaged myosepta and detachment of myofibers in the affected fish. Laminin-α2 deficiency also resulted in growth defects in the brain and eye of the mutant fish. This laminin-α2 deficient mutant fish represents a novel disease model to develop therapies for modulating splicing defects in congenital muscular dystrophies and to restore the muscle function in human patients with CMD.

QTL analysis from a Limousin-Jersey double backcross herd was conducted using QTL Express software with cohort and breed as the fixed effects. Nine QTL suggested to have an association with muscularity were identified on cattle chromosomes BTA 1, 2, 3, 4, 5, 8, 12, 14 and 17. The myostatin gene is located at the centromeric end of chromosome 2 and not surprisingly, the Limousin myostatin F94L variant accounted for the QTL on BTA2. However, when the myostatin F94L genotype was included as an additional fixed effect, the QTL on BTA17 was also no longer significant. This result suggests that there may be gene(s that have epistatic effects with myostatin located on cattle chromosome 17. Based on the position of the QTL in base pairs, all the genes that reside in the region were determined using the Ensembl data base (www.ensembl.org. There were two potential candidate genes residing within these QTL regions were selected. They were Smad nuclear interacting protein 1 (SNIP1 and similar to follistatin-like 5 (FSTL5.

    CT scans of muscles in patients with limb girdle type (LG), myotonic type (MYD) and Duchenne type (DMD) dystrophies were obtained at five different body levels: the neck, L3 vertebral body, pelvic girdle, thigh and lower leg. CT numbers, cross sectional areas (CSA) and %CSA of muscle or fat were evaluated in each muscle. The characteristic CT patterns for each type of muscular dystrophy were obtained. Compared with DMD, the gracilis and soleus were more severely damaged in LG and the biceps femoris remained relatively preserved among the hamstrings. In addition, the multifidus of the neck and sternocleidomastoid also were more severely damaged in MYD. This study suggests that CT scan will be useful in the differential diagnosis of these types of muscular dystrophy as well as in planning appropriate rehabilitation and detecting damaged muscles.

    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.

    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.

    Calf pain is a common complaint among runners of all ages but is most frequent in masters athletes. This article focuses on injuries to the triceps surae or true 'calf muscles.' The most common calf injury is a tear of the medial gastrocnemius muscle (Tennis Leg) but other structures including the lateral gastrocnemius, plantaris and soleus also may be the cause of muscular pain. This article looks at the presentation, evaluation, and treatment of these injuries. We also highlight some examples of musculoskeletal ultrasound which is a valuable tool for rapid diagnosis of the cause and extent of injury.

    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.)

  5. Congenital malaria in China.

    2014-03-01

    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.

    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 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

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.”

    Pulmonary oxygen uptake (V˙O2) kinetics and heart rate kinetics are influenced by age and fitness. Muscular V˙O2 kinetics can be estimated from heart rate and pulmonary V˙O2. In this study the applicability of a test using pseudo-random binary sequences in combination with a model to estimate muscular V˙O2 kinetics was tested. Muscular V˙O2 kinetics were expected to be faster than pulmonary V˙O2 kinetics, slowed in aged subjects and correlated with maximum V˙O2 and heart rate kinetics. 27 elderly subjects (73±3 years; 81.1±8.2 kg; 175±4.7 cm) participated. Cardiorespiratory kinetics were assessed using the maximum of cross-correlation functions, higher maxima implying faster kinetics. Muscular V˙O2 kinetics were faster than pulmonary V˙O2 kinetics (0.31±0.1 vs. 0.29±0.1 s; p=0.004). Heart rate kinetics were not correlated with muscular or pulmonary V˙O2 kinetics or maximum V˙O2. Muscular V˙O2 kinetics correlated with maximum V˙O2 (r=0.35; p=0.033). This suggests, that muscular V˙O2 kinetics are faster than estimates from pulmonary V˙O2 and related to maximum V˙O2 in aged subjects. In the future this experimental approach may help to characterize alterations in muscular V˙O2 under various conditions independent of motivation and maximal effort. © Georg Thieme Verlag KG Stuttgart · New York.

    Golden Retriever muscular dystrophy is an inherited, degenerative myopathy due to the absence of dystrophin and is used as a model of Duchenne muscular dystrophy of young boys. This report describes the radiographic abnormalities of Golden Retriever muscular dystrophy in 26 dogs. The thoracic abnormalities included diaphragmatic asymmetry (18/26), diaphragmatic undulation (18/26), and gastro-esophageal hiatal hernia (6/26). Pelvic abnormalities included narrowing of the body of the ilia (14/19), ventral deviation and curvature of the tuber ischii (14/19), elongation of the obturator foramen with a decrease in opacity of the surrounding bone (12/19), and lateral flaring of the wings of the ilia (12/19). Abdominal abnormalities consisted of hepatomegaly (14/22) and poor serosal detail (12/22). The unique thoracic abnormalities were a consistent finding in affected Golden Retriever muscular dystrophy dogs. The diagnosis of muscular dystrophy should be included in the differential list if the combination of diaphragm undulation and asymmetry, and gastro-esophageal hiatal hernia are identified. These diaphragmatic abnormalities are related to hypertrophy and hyperplasia of the diaphragm. Additionally, the skeletal changes of pelvic tilt, elongation of the pelvis, widening of the obturator foramina and thinning of the ischiatic tables appear to be specific to Golden Retriever muscular dystrophy in dogs. These pelvic abnormalities are most likely secondary to bone remodeling associated with the progressive skeletal myopathy and subsequent contracture/fibrosis.

    Objective To report the echocardiographic evaluation of 103 infants with presumed congenital Zika syndrome. Methods An observational retrospective study was performed at Instituto de Medicina Integral Prof. Fernando Figueira (IMIP), Recife, Brazil. 103 infants with presumed congenital Zika syndrome. All infants had microcephaly and head computed tomography findings compatible with congenital Zika syndrome. Zika IgM antibody was detected in cerebrospinal fluid samples of 23 infants. In 80 infants, the test was not performed because it was not available at that time. All infants had negative serology for HIV, syphilis, rubella, cytomegalovirus and toxoplasmosis. A complete transthoracic two-dimensional, M-mode, continuous wave and pulsed wave Doppler and color Doppler echocardiographic (PHILIPS HD11XE or HD15) examination was performed on all infants. Results 14/103 (13.5%) echocardiograms were compatible with congenital heart disease: 5 with an ostium secundum atrial septal defect, 8 had a hemodynamically insignificant small apical muscular ventricular septal defect and one infant with dyspnea had a large membranous ventricular septal defect. The echocardiograms considered normal included 45 infants with a persistent foramen ovale and 16 with a minimum patent ductus arteriosus. Conclusions Preliminarily this study suggests that congenital Zika syndrome may be associated with an increase prevalence of congenital heart disease. However the types of defects noted were septal defects, a proportion of which would not be hemodynamically significant. PMID:28426680

  14. Spinal and bulbar muscular atrophy.

    Lieberman, Andrew P

    2018-01-01

    Spinal and bulbar muscular atrophy (SBMA) is an adult-onset degenerative disorder of the neuromuscular system resulting in slowly progressive weakness and atrophy of the proximal limb and bulbar muscles. The disease is caused by the expansion of a CAG/glutamine tract in the amino-terminus of the androgen receptor. That SBMA exclusively affects males reflects the fact that critical pathogenic events are hormone-dependent. These include translocation of the polyglutamine androgen receptor from the cytoplasm to the nucleus and unfolding of the mutant protein. Studies of the pathology of SBMA subjects have revealed nuclear aggregates of the mutant androgen receptor, loss of lower motor neurons in the brainstem and spinal cord, and both neurogenic and myopathic changes in skeletal muscle. Mechanisms underlying disease pathogenesis include toxicity in both lower motor neurons and skeletal muscle, where effects on transcription, intracellular transport, and mitochondrial function have been documented. Therapies to treat SBMA patients remain largely supportive, although experimental approaches targeting androgen action or promoting degradation of the mutant androgen receptor protein or the encoding RNA are under active study.

    The phenotypic severity of congenital muscular dystrophy-dystroglycanopathy (MDDG) syndromes associated with aberrant glycosylation of α-dystroglycan ranges from the severe Walker-Warburg syndrome or muscle-eye-brain disease to mild, late-onset, isolated limb-girdle muscular dystrophy without neural involvement. However, muscular dystrophy is invariably found across the spectrum of MDDG patients. Using linkage mapping and whole-exome sequencing in two families with an unexplained neurodevelopmental disorder, we have identified homozygous and compound heterozygous mutations in B3GALNT2. The first family comprises two brothers of Dutch non-consanguineous parents presenting with mild ID and behavioral problems. Immunohistochemical analysis of muscle biopsy revealed no significant aberrations, in line with the absence of a muscular phenotype in the affected siblings. The second family includes five affected individuals from an Iranian consanguineous kindred with mild-to-moderate intellectual disability (ID) and epilepsy without any notable neuroimaging, muscle, or eye abnormalities. Complementation assays of the compound heterozygous mutations identified in the two brothers had a comparable effect on the O-glycosylation of α-dystroglycan as previously reported mutations that are associated with severe muscular phenotypes. In conclusion, we show that mutations in B3GALNT2 can give rise to a novel MDDG syndrome presentation, characterized by ID associated variably with seizure, but without any apparent muscular involvement. Importantly, B3GALNT2 activity does not fully correlate with the severity of the phenotype as assessed by the complementation assay.

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

    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.

    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.

    Full Text Available This study aimed to analyze the correlation between the phenotype and genotype of Chinese patients with early-onset lamin A (LMNA-related muscular dystrophy (MD. The clinical and myopathological data of 21 Chinese pediatric patients with early-onset LMNA-related MD were collected and analyzed. LMNA gene mutation analysis was performed by direct sequencing of genomic DNA. Sublocalization of wild-type and mutant proteins were observed by immunofluorescence using cultured fibroblasts and human embryonic kidney 293 (HEK 293 cell. Seven patients were diagnosed with Emery-Dreifuss muscular dystrophy (EDMD and 14 were diagnosed with LMNA-associated congenital muscular dystrophy (L-CMD. Four biopsy specimens from the L-CMD cases exhibited inflammatory changes. Abnormal nuclear morphology was observed with both transmission electron microscopy and lamin A/C staining. We identified 10 novel and nine known LMNA gene mutations in the 21 patients. Some mutations (c.91G>A, c.94_96delAAG, c.116A>G, c.745C>T, c.746G>A, and c.1580G>C were well correlated with EDMD or L-CMD. LMNA-related MD has a common symptom triad of muscle weakness, joint contractures, and cardiac involvement, but the severity of symptoms and disease progression differ greatly. Inflammatory change in biopsied muscle is a characteristic of early-stage L-CMD. Phenotype-genotype analysis determines that some mutations are well correlated with LMNA-related MD.

    Full Text Available Duchenne muscular dystrophy (DMD and Becker muscular dystrophy (BMD are caused by mutations in the dystrophin gene. We studied 106 patients with a diagnosis of probable DMD/BMD by analyzing 20 exons of the dystrophin gene in their blood and, in some of the cases, by immunohistochemical assays for dystrophin in muscle biopsies. In 71.7% of the patients, deletions were found in at least one of the exons; 68% of these deletions were in the hot-spot 3' region. Deletions were found in 81.5% of the DMD cases and in all the BMD cases. The cases without deletions, which included the only woman in the study with DMD, had dystrophin deficiency. The symptomatic female carriers had no deletions but had abnormal dystrophin distribution in the sarcolemma (discontinuous immunostains. The following diagnoses were made for the remaining cases without deletions with the aid of a muscle biopsy: spinal muscular atrophy, congenital myopathy; sarcoglycan deficiency and unclassified limb-girdle muscular dystrophy. Dystrophin analysis by immunohistochemistry continues to be the most specific method for diagnosis of DMD/BMD and should be used when no exon deletions are found in the dystrophin gene in the blood.As distrofias musculares de Duchenne (DMD e de Becker (DMB são doenças causadas por mutação no gene da distrofina.

    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

    Full Text Available Abstract Background Hydatidosis is a zoonosis caused by Echinococcus granulosus, and ingesting eggs released through the faeces from infected dogs infects humans. The location of the hydatid cysts is mostly hepatic and/or pulmonary, whereas musculoskeletal hydatidosis is very rare. Case presentation We report an unusual case of primary muscular hydatidosis in proximity of the big adductor in a young Sicilian man. The patient, 34 years old, was admitted to the Department of Infectious and Tropical Diseases for ultrasonographic detection, with successive confirmation by magnetic resonance imaging, of an ovular mass (13 × 8 cm in the big adductor of the left thigh, cyst-like, and containing several small cystic formations. Serological tests for hydatidosis gave negative results. A second drawing of blood was done 10 days after the first one and showed an increase in the antibody titer for hydatidosis. The patient was submitted to surgical excision of the lesion with perioperatory prophylaxis with albendazole. The histopathological examination of the bioptic material was not diriment in the diagnosis, therefore further tests were performed: additional serological tests for hydatidosis for the evaluation of IgE and IgG serotype (Western Blot and REAST, and molecular analysis of the excised material. These more specific serological tests gave positive results for hydatidosis, and the sequencing of the polymerase chain reaction products from the cyst evidenced E. granulosus DNA, genotype G1. Any post-surgery complications was observed during 6 following months. Conclusion Cystic hydatidosis should always be considered in the differential diagnosis of any cystic mass, regardless of its location, also in epidemiological contests less suggestive of the disease. The diagnosis should be achieved by taking into consideration the clinical aspects, the epidemiology of the disease, the imaging and immunological tests but, as demonstrated in this case, without

    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.

    Two hereditary muscular dystrophies similar to human progressive muscular dystrophy (P.M.D. Duchenne type) have been isolated in animals, one in mouse, the other in chicken. The decrease in the activity of glycogenolytic enzymes is similar to that observed in denervated muscle. Isozymic fetal types for several muscular enzymes have been observed as well in chicken as in man, but this fetal type may also be found in neurogenic atrophy. The release in circulation of muscle enzymes seems more specific. But the origin of the genetic lesion is still unknown. We describe here the three different theories about this problem: i.e. neurogenic, vascular, or myogenic. This last theory implies a trouble of membrane permeability.

    Full Text Available The literature review gives data on the role of mitochondrial disorders in the pathogenesis of different progressive muscular dystrophies. It describes changes in Duchenne, limb-girdle, facial scapulohumeral (Landuzi—Degerina muscular dystrophies. The review is based on both clinical and experimental animal studies. Along with the implication of mitochondria in the pathogenesis of the diseases, it describes muscular dystrophy treatment options compensating for energy disorders and overcoming oxidative stress and mitochondrial dysfunction. Mitochondrial studies in different muscle diseases hand physicians treatment modalities that fail to lead to recovery, but compensate for disorders caused by mutations in the genetic apparatus. 

  14. Muscular pathology: echographic and NMR imaging aspects

    A comparison of echographic techniques and NMR imaging has been done for the diagnosis of muscular trauma and tumor pathologies. In traumatic pathology, the echographic analysis allows to determine the complete assessment of recent muscular injuries. NMR imaging can be used in granuloma or fibrous callosity appreciation and for the analysis of deep injury (muscles and muscles-tendon junctions) and of muscular aponeurosis. Echography must be used together with color coding Doppler technique in the diagnosis of tumor pathology and for the study of slow fluxes. The recently available energy Doppler technique seems to be powerful in the study of vascularization of small expansive formations, but their extension to adjacent bone or tissue can only be appreciated using NMR imaging.

    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.

    To investigate the role of the muscular renin-angiotensin system (RAS) in human muscular dystrophy, we used immunohistochemistry and Western blotting to examine the cellular localization of angiotensin-converting enzyme (ACE), the angiotensin II type 1 receptor (AT1) and the angiotensin II type 2 receptor (AT2) in muscle biopsies from patients with Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), and congenital muscular dystrophy (CMD). In normal muscle, ACE was expressed in vascular endothelial cells and neuromuscular junctions (NMJs), whereas AT1 was immunolocalized to the smooth muscle cells of blood vessels and intramuscular nerve twigs. AT2 was immunolocalized in the smooth muscle cells of blood vessels. These findings suggest that the RAS has a functional role in peripheral nerves and NMJs. ACE and AT1, but AT2 immunoreactivity were increased markedly in dystrophic muscle as compared to controls. ACE and the AT1 were strongly expressed in the cytoplasm and nuclei of regenerating muscle fibers, fibroblasts, and in macrophages infiltrating necrotic fibers. Double immunolabeling revealed that activated fibroblasts in the endomysium and perimysium of DMD and CMD muscle were positive for ACE and AT1. Triple immunolabeling demonstrated that transforming growth factor-beta1 (TGF-beta1) and ACE were colocalized on the cytoplasm of activated fibroblasts in dystrophic muscle. Furthermore, Western blotting showed increases in the expression of AT1 and TGF-beta1 protein in dystrophic muscle, which coincided with our immunohistochemical results. The overexpression of ACE and AT1 in dystrophic muscle would likely result in the increased production of Ang II, which may act on these cells in an autocrine manner via AT1. The activation of AT1 may induce fibrous tissue formation through overexpression of TGF-beta1, which potently activates fibrogenesis and suppresses regeneration. In conclusion, our results imply that the intramuscular RAS-TGF-beta1 pathway

    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.

    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

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

    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.)

    To investigate both volume and length of the three muscle compartments of the normal and the affected leg in unilateral congenital clubfoot. Volumetric magnetic resonance imaging (VMRI) of the anterior, lateral and postero-medial muscular compartments of both the normal and the clubfoot leg was obtained in three groups of seven patients each, whose mean age was, respectively, 4.8 months, 11.1 months and 4.7 years. At diagnosis, all the unilateral congenital clubfeet had a Pirani score ranging from 4.5 to 5.5 points, and all of them had been treated according to a strict Ponseti protocol. All the feet had percutaneous lengthening of the Achilles tendon. A mean difference in both volume and length was found between the three muscular compartments of the leg, with the muscles of the clubfoot side being thinner and shorter than those of the normal side. The distal tendon of the tibialis anterior, peroneus longus and triceps surae (Achilles tendon) were longer than normal on the clubfoot side. Our study shows that the three muscle compartments of the clubfoot leg are thinner and shorter than normal in the patients of the three groups. The difference in the musculature volume of the postero-medial compartment between the normal and the affected side increased nine-fold from age group 2 to 3, while the difference in length increased by 20 %, thus, showing that the muscles of the postero-medial compartment tend to grow in both thickness and length much less than the muscles of the other leg compartments.

    Full Text Available Abstract Introduction Diamond-Blackfan anemia and Duchenne muscular dystrophy are two rare congenital anomalies. Both anomalies occurring in the same child is extremely rare. Allogeneic hematopoietic stem cell transplantation is a well-established therapy for Diamond-Blackfan anemia. However, in patients with Duchenne muscular dystrophy, stem cell therapy still remains experimental. Case presentation We report the case of a nine-year-old boy of north Indian descent with Diamond-Blackfan anemia and Duchenne muscular dystrophy who underwent successful allogeneic hematopoietic stem cell transplantation. He is transfusion-independent, and his Duchenne muscular dystrophy has shown no clinical deterioration over the past 45 months. His creatine phosphokinase levels have significantly decreased to 300 U/L from 14,000 U/L pre-transplant. The patient is 100% donor chimera in the hematopoietic system, and his muscle tissue has shown 8% to 10.4% cells of donor origin. Conclusion Our patient's Diamond-Blackfan anemia was cured by allogeneic hematopoietic stem cell transplantation. The interesting clinical observation of a possible benefit in Duchenne muscular dystrophy cannot be ruled out. However, further clinical follow-up with serial muscle biopsies and molecular studies are needed to establish this finding.

    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.

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

    Chakyrov, B.; Samardzhiev, A.

    1977-01-01

    The effect of intramuscularly and intravenously adminostered atriphos on the muscular circulation was studied with radioactive xenon in 12 children with progressive muscular dystrophy. After combined local intramuscular injection of ATP (atriphos) with the radioactive marker a 12-fold increment of muscular circulation ensues, lasting about 15 minutes. No vasodilatating effect on the muscular flow was oberved after intravenous injection of 20-40 mg of atriphos. It is believed that intramuscular administration of atriphos produced dilatation of capillaries and of the venous part of the muscular circulation. (author)

    We wanted to predict the prognosis of patients with CMT by the A/N ratio of the thickness and the circumference of the SCM muscle on ultrasonography, and we wanted to correlate the echogenecity of the affected muscle and the prognosis. Ultrasonography was performed on 24 patients from June 2004 to March 2007. We measured the thickness and the cross sectional circumference of the SCM muscle at three levels; below the mastoid process, at the level of the carotid artery bifurcation and at the level of the sternum and clavicle. The ratio of the affected side to the normal side (the A/N ratio) of the SCM muscle was calculated. We performed followed up ultrasonography at 2 months intervals until the end of treatment. The Wilcoxon signed-rank test was used to correlate the A/N ratio before and after the treatment. Spearman's rank test was used to correlate the A/N ratio and the total treatment duration. Paired T-tests were used to correlate the echogenecity of the SCM muscle and the treatment duration divided by less than or greater than 12 months. With measuring the thickness of the SCM muscle, the A/N ratio after treatment (1.36) was decreased compared with the initial A/N ratio (2.31) (p<0.05). The correlation between the A/N ratio of the thickness with the total treatment duration was statistically significant (p<0.05). The echogenecity of the affected SCM muscle was not correlated with the duration of treatment. The A/N ratio of the thickness of the SCM muscle is useful to predict the prognosis of patients with CMT

    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.

    Full Text Available Intra-muscular hemangiomas (IMH are relatively uncommon benign vascular tumors, which account for less than 1% of all hemangiomas. IMH may be presented as a perceived sporting injury. Diagnosis of this lesion is important not only because of its rarity, but also due to dangers posed by misdiagnosis and mismanagement. They must be considered in the differential diagnosis of unexplained pain and swelling in muscles. IMH occurring in the oral cavity is reviewed below.

    Duchenne muscular dystrophy is a dystrophinopathy affecting males that is associated with multiple organ system complications. To our knowledge urological complications of Duchenne muscular dystrophy have been described only anecdotally to date. We reviewed the medical charts of 135 patients with Duchenne or Duchenne-Becker muscular dystrophy for demographics and disease progression, urological diagnoses, intervention and followup. Of 135 patients 67 (50%) had at least 1 documented urological diagnosis and 38 (28%) had multiple manifestations. Lower urinary tract symptoms were the most common urological diagnosis (32% of patients). Survival analysis revealed a median age at onset of lower urinary tract symptoms of 23 years (95% CI 17.7-23.9). Intervention was required in 12 patients (9%), most commonly due to nephrolithiasis. Urological morbidity increased with Duchenne muscular dystrophy progression when stratified by clinical progression. Lower urinary tract symptoms were more common in nonambulatory patients (40.7% vs 19%, p = 0.007), those with a diagnosis of scoliosis (44% vs 19.7%, p = 0.003) and/or scoliosis spine surgery (60% vs 22%, p <0.001), and those on invasive respiratory support (53% vs 29%, p = 0.046). Likewise, nephrolithiasis was more common in nonambulatory patients (10% vs 0%, p = 0.017), those with scoliosis (12% vs 0%, p = 0.004) and/or scoliosis spine surgery (20% vs 1%, p <0.001), and those on invasive respiratory support (29% vs 3%, p <0.001). Only 28% of patients with a urological manifestation were referred to urology. As these patients transition into adolescence and adulthood, the increased prevalence of urological manifestations warrants increased awareness and referral to urologists.

    Full Text Available Gerrit Haaker, Albert Fujak Department of Orthopaedic Surgery, Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany Abstract: Spinal muscular atrophy (SMA is a hereditary neuromuscular disease of lower motor neurons that is caused by a defective "survival motor neuron" (SMN protein that is mainly associated with proximal progressive muscle weakness and atrophy. Although SMA involves a wide range of disease severity and a high mortality and morbidity rate, recent advances in multidisciplinary supportive care have enhanced quality of life and life expectancy. Active research for possible treatment options has become possible since the disease-causing gene defect was identified in 1995. Nevertheless, a causal therapy is not available at present, and therapeutic management of SMA remains challenging; the prolonged survival is increasing, especially orthopedic, respiratory and nutritive problems. This review focuses on orthopedic management of the disease, with discussion of key aspects that include scoliosis, muscular contractures, hip joint disorders, fractures, technical devices, and a comparative approach of conservative and surgical treatment. Also emphasized are associated complications including respiratory involvement, perioperative care and anesthesia, nutrition problems, and rehabilitation. The SMA disease course can be greatly improved with adequate therapy with established orthopedic procedures in a multidisciplinary therapeutic approach.

  8. Management of myocardial damage in muscular dystrophy

    Heart failure (HF) is a fatal complication in many muscular dystrophy cases and has become the most common cause of death in Duchenne muscular dystrophy (DMD) since 2001. HF deaths in DMD occur in young patients and increase, along with respiratory failure, in older patients. Managing HF, therefore, is the most important component of DMD treatment. Management of HF is necessary in DMD patients of all ages because myocardial damage progresses regardless of age and disability. Electrocardiography, echocardiography, myocardial single-photon emission computed tomography (SPECT), and natriuretic peptides are used for the diagnosis of myocardial damage and chronic HF. Tissue Doppler echocardiography is in particularly useful for early detection of minute myocardial damage and dysfunction in DMD. The first-line drugs for chronic HF are angiotensin-converting enzyme inhibitors, and the prognosis of DMD patients has been improved using these drugs and beta-blockers. Diuretics are added in the presence of pulmonary congestion. Digoxin is most effective at a blood level of 0.5-0.8 ng/mL because of its pharmacokinetics in DMD. Surgical treatment may be necessary in cases of intractable HF. Cardiac resynchronization therapy (biventricular pacing), a treatment with an artificial pacemaker, is indicated for cases that meet specific criteria, including HF with ventricular dyssynchrony. Applications of partial left ventriculectomy (Batista procedure) and left ventricular assist devices in muscular dystrophy are likely in the near future. (author)

  9. Congenital Short QT Syndrome

    2004-04-01

    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.

Aims and Objectives: The aim of this study is to determine the frequency of CH in neonates. Settings and Design: This cross-sectional study was conducted in neonatal units of the Department of Pediatrics Unit-I, King Edward Medical University/Mayo Hospital, Lahore and Lady Willington Hospital Lahore in 6 months (January-June 2011. Materials and Methods: Sample was collected by non-probability purposive sampling. After consent, 550 newborn were registered for the study. Demographic data and relevant history was recorded. After aseptic measures, 2-3 ml venous blood analyzed for thyroid-stimulating hormone (TSH level by immunoradiometric assay. Treatment was started according to the individual merit as per protocol. Statistical Analysis Used: Data was analyzed by SPSS 17 and Chi-square test was applied to find out the association of CH with different variables. Results: The study population consisted of 550 newborns. Among 550 newborns, 4 (0.8% newborns had elevated TSH level. CH had statistically significant association with mother′s hypothyroidism (P value 0.000 and mother′s drug intake during the pregnancy period (P value 0.013. Conclusion: CH is 0.8% in neonates. It has statistically significant association with mother′s hypothyroidism and mother′s drug intake during pregnancy.

    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.

    2003-01-01

    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.

    2013-07-01

    Congenital abnormalities of the penis are usually diagnosed at birth and pose aesthetic and functional problems sometimes requiring surgical management. 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.

    2006-01-01

    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.)

    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.

    Disease inclusion in the newborn screening (NBS) panel should consider the opinions of those most affected by the outcome of screening. We assessed the level and factors that affect parent attitudes regarding NBS panel inclusion of Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), and spinal muscular atrophy (SMA). The attitudes toward NBS for DMD, BMD, and SMA were surveyed and compared for 2 categories of parents, those with children affected with DMD, BMD, or SMA and expectant parents unselected for known family medical history. The level of support for NBS for DMD, BMD, and SMA was 95.9% among parents of children with DMD, BMD, or SMA and 92.6% among expectant parents. There was strong support for NBS for DMD, BMD, and SMA in both groups of parents. Given advances in diagnostics and promising therapeutic approaches, discussion of inclusion in NBS should continue.

    Full Text Available Summary: Generating human skeletal muscle models is instrumental for investigating muscle pathology and therapy. Here, we report the generation of three-dimensional (3D artificial skeletal muscle tissue from human pluripotent stem cells, including induced pluripotent stem cells (iPSCs from patients with Duchenne, limb-girdle, and congenital muscular dystrophies. 3D skeletal myogenic differentiation of pluripotent cells was induced within hydrogels under tension to provide myofiber alignment. Artificial muscles recapitulated characteristics of human skeletal muscle tissue and could be implanted into immunodeficient mice. Pathological cellular hallmarks of incurable forms of severe muscular dystrophy could be modeled with high fidelity using this 3D platform. Finally, we show generation of fully human iPSC-derived, complex, multilineage muscle models containing key isogenic cellular constituents of skeletal muscle, including vascular endothelial cells, pericytes, and motor neurons. These results lay the foundation for a human skeletal muscle organoid-like platform for disease modeling, regenerative medicine, and therapy development. : Maffioletti et al. generate human 3D artificial skeletal muscles from healthy donors and patient-specific pluripotent stem cells. These human artificial muscles accurately model severe genetic muscle diseases. They can be engineered to include other cell types present in skeletal muscle, such as vascular cells and motor neurons.

    2018-06-01

    Full Text Available LAMA2-related muscular dystrophy (LAMA2 MD is the most common and fatal form of early-onset congenital muscular dystrophies. Due to the large size of the laminin α2 cDNA and heterotrimeric structure of the protein, it is challenging to develop a gene-replacement therapy. Our group has developed a novel adeno-associated viral (AAV vector carrying the mini-agrin, which is a non-homologous functional substitute for the mutated laminin α2. A significant therapeutic effect in skeletal muscle was observed in our previous study using AAV serotype 1 (AAV1. In this investigation, we examined AAV9 vector, which has more widespread transduction than AAV1, to determine if the therapeutic effects could be further improved. As expected, AAV9-mini-agrin treatment offered enhanced therapeutic effects over the previously used AAV1-mini-agrin in extending mouse lifespan and improvement of muscle pathology. Additionally, overexpression of mini-agrin in peripheral nerves of dyw/dyw mice partially amended nerve pathology as evidenced by improved motor function and sensorimotor processing, partial restoration of myelination, partial restoration of basement membrane via EM examination, as well as decreased regeneration of Schwann cells. In conclusion, our studies indicate that overexpression of mini-agrin into dyw/dyw mice offers profound therapeutic effects in both skeletal muscle and nervous system.

    Full Text Available Muscular dystrophy is a group of diseases that is characterized by progressive muscle wasting and the weakness of variable distribution and severity. On the basis of the distribution of predominant muscle weakness, there are many different kinds of muscular dystrophy. Some dystrophies are especially frequent in certain populations. There are no studies on the prevalence of muscular dystrophy in Iran. This study was aimed to survey the prevalence of muscular dystrophy among Iranian patients with muscular disorders. This analytical cross-sectional study was conducted on 1000 patients with musculoskeletal disorders who visited the dystrophy association of Bou-Ali Hospital (Tehran from June 2014 to June 2016. Patients’ data were extracted using a checklist that included age, gender, age of onset, family history, findings from clinical diagnostic tests and types of muscular dystrophy. The clinical findings were the results of genetic tests; EMG-NCV; para-clinical findings, including LDH and CPK; and pathological findings. All data were analyzed by SPSS V.22 (IBM Inc., NY with Chi Square and One way ANOVA tests. All analyses were performed with P = 0.05 considered as the threshold of statistical significant. Out of the 337 patients studied, 262 (77.7% were male and 75 (22.3% were female. Subjects had a mean (± SD age of 26.08 (± 11.86 years with an age range of 3 to 59 years. The most common types of muscular dystrophy were found to be Duchenne dystrophy (131 cases, 38.9%, limb-girdle dystrophy (91 cases, 27%, Becker dystrophy (58 cases, 17.2%, FSHD dystrophy (31 cases, 9.2%, and SMA (26 cases, 7.7%, respectively. The results showed that a statistically significant relationship between dystrophy types and gender, age, family history, age of diagnosis, CPK and LDH levels (P < 0.001. There were no statistical relationship between dystrophy types and pathological findings (P = 0.57, EMG-NCV test results (P = 0.062, and genetic findings (P = 0

    Pediatric neuromuscular disorders comprise a large variety of disorders that can be classified based on their neuroanatomical localization, patterns of weakness, and laboratory test results. Over the last decade, the field of translational research has been active with many ongoing clinical trials. This is particularly so in two common pediatric neuromuscular disorders: Duchenne muscular dystrophy and spinal muscular atrophy. Although no definitive therapy has yet been found, numerous active areas of research raise the potential for novel therapies in these two disorders, offering hope for improved quality of life and life expectancy for affected individuals.

    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.

  13. Muscular anatomy of the Podocoryna carnea hydrorhiza.

    Buss, Leo W; Anderson, Christopher; Bolton, Edward W

    2013-01-01

    The muscular anatomy of the athecate hydroid Podocoryna carnea hydrorhiza is elucidated. The polyp-stolon junction is characterized by an opening, here called the chloe, in the otherwise continuous hydrorhizal perisarc. The chloe is elliptical when the polyp first arises, but takes on a more complex outline as multiple stolons anastomose to communicate with that polyp. Surrounding the polyp base are spots, here called anchors, which autofluoresce at the same wavelengths as perisarc and which, like perisarc, contain chitin as assessed by Calcofluor White, Congo Red and wheat germ agglutinin staining. Anchors remain after living tissues are digested using KOH. Collagen IV staining indicates that the mesoglea is pegged to the anchors and rhodamine phallodin staining detects cytoskeletal F-actin fibers of the basal epidermis surrounding the anchors. Longitudinal muscle fibers of the polyp broaden at the polyp base and are inserted into the mesoglea of the underlying stolon, but were neither observed to extend along the stolonal axis nor to attach to the anchors. Circular muscular fibers of the polyp extend into stolons as a dense collection of strands running along the proximal-distal axis of the stolon. These gastrodermal axial muscular fibers extend to the stolon tip. Epidermal cells at the stolon tip and the polyp bud display a regular apical latticework of F-actin staining. A similar meshwork of F-actin staining was found in the extreme basal epidermis of all stolons. Immunohistochemical staining for tubulin revealed nerves at stolon tips, but at no other hydrorhizal locations. These studies bear on the mechanisms by which the stolon tip and polyp bud pulsate, the manner in which the stolon lumen closes, and on the developmental origin of the basal epidermis of the hydrorhiza.

  14. Nose muscular dynamics: the tip trigonum.

    2001-10-01

    In 1995, the senior author (E.E.F.) published an article in which he described the musculus digastricus septi nasi labialis. In the article presented here, work carried out by anatomists and other researchers who, over the last two centuries, studied nose muscular dynamics is described. The present study is based on Gray's Anatomy, which, in 1858, first described the nasal tip muscles, along with the other nasal muscles. Later works not only used different terminology for these muscles but also ignored some, creating tremendous confusion. The study presented here provides an update of the exact terms, location, insertions, and muscle functions of the muscles of the nose. Each nose muscle is described with regard to the two portions able to produce separate contractions. In this study, the term "dual function" is used and characterizes the nasal mimetic muscles that do not have well-defined fascia. Therefore, there is doubt about the existence of a real nasal superficial muscle aponeurotic system. The musculus myrtiformis seems to have a dual function, inserting in the canine fosse and in the periosteum of the central incisors, forming two portions-one to the septum and the other to the nostril-each of which has specific functions. This study has been based on research in physiognomy, the science of expression. With regard to the basis for nose expressions, common anatomical research is excluded because it provides a different view of the dynamics studied to date. The term trigonum musculare apicis nasi defines the interaction of the musculi compressor narium minor and dilator naris anterior, connecting with the columellar bundle of the musculus digastricus and levering the nasal spine. This muscular trigone creates circular concentric and eccentric movements of the nasal tip.

    Swallowing dysfunction has been reported in Duchenne muscular dystrophy (DMD), but has not been studied in Becker muscular dystrophy (BMD). The aims of this study were to report the characteristics of swallowing dysfunction in BMD compared with DMD. The study participants were 18 patients with BMD and 18 patients with DMD. All the patients were examined using videofluorography during swallowing of 5 mL of fluid. The penetration-aspiration scale (P-A scale) and the videofluorographic dysphagia scale (VDS) were used to evaluate dysphagia. Swinyard functional ability stage was not significantly different between the BMD and DMD groups. Rate of aspiration, P-A scale score, and total VDS score did not differ across groups, but the VDS item score for laryngeal elevation was lower in the BMD group than in the DMD group (median scores 4.5 and 9, respectively; p Becker muscular dystrophy (BMD) was not well known. Eighteen patients with BMD and 18 patients with Duchenne muscular dystrophy were examined with videofluorography. Patients with BMD have swallowing problems similar to those observed in patients with DMD.

    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.)

    We report a case of complete atrioventricular (AV) block in a 40-year-old patient with Duchenne muscular dystrophy (DMD). While he was bed-ridden and required mechanical ventilation, his cardiac involvement was mild. He had the deletion of exon 45-52 in the dystrophin gene. He underwent transient complete AV block and came to require pacemaker implantation due to recurrence of complete AV block ten days after the first attack. Electrophysiological study revealed mild prolonged AH and HV interval. Although DMD patients with AV block have been rarely reported so far, attention should be paid to AV block for patients who prolonged their lives.

  6. B4GALNT2 (GALGT2) Gene Therapy Reduces Skeletal Muscle Pathology in the FKRP P448L Mouse Model of Limb Girdle Muscular Dystrophy 2I.

    Thomas, Paul J; Xu, Rui; Martin, Paul T

    2016-09-01

    Overexpression of B4GALNT2 (previously GALGT2) inhibits the development of muscle pathology in mouse models of Duchenne muscular dystrophy, congenital muscular dystrophy 1A, and limb girdle muscular dystrophy 2D. In these models, muscle GALGT2 overexpression induces the glycosylation of α dystroglycan with the cytotoxic T cell glycan and increases the overexpression of dystrophin and laminin α2 surrogates known to inhibit disease. Here, we show that GALGT2 gene therapy significantly reduces muscle pathology in FKRP P448Lneo(-) mice, a model for limb girdle muscular dystrophy 2I. rAAVrh74.MCK.GALGT2-treated FKRP P448Lneo(-) muscles showed reduced levels of centrally nucleated myofibers, reduced variance, increased size of myofiber diameters, reduced myofiber immunoglobulin G uptake, and reduced muscle wasting at 3 and 6 months after treatment. GALGT2 overexpression in FKRP P448Lneo(-) muscles did not cause substantial glycosylation of α dystroglycan with the cytotoxic T cell glycan or increased expression of dystrophin and laminin α2 surrogates in mature skeletal myofibers, but it increased the number of embryonic myosin-positive regenerating myofibers. These data demonstrate that GALGT2 overexpression can reduce the extent of muscle pathology in FKRP mutant muscles, but that it may do so via a mechanism that differs from its ability to induce surrogate gene expression.

    Full Text Available Miotonia é o fenômeno da diminuição da velocidade de relaxamento muscular após contração, estímulo mecânico ou elétrico. As miotonias congênitas são afecções hereditárias e não apresentam distrofia muscular. Atualmente, a tendência é agrupá-las como doenças de canais iônicos, juntamente com as paralisias periódicas. Foram acompanhados sete pacientes, seis do sexo masculino e um do sexo feminino, com idade entre 16 e 48 anos (média 27 anos e início dos sintomas entre 1 e 10 anos (média S anos, que apresentavam fenômeno miotônico desencadeado por contração intensa e hipertrofia muscular global. Três pacientes foram diagnosticados como miotonia generalizada tipo Becker por apresentarem herança autossômica recessiva e/ou episódios transitórios de fraqueza muscular.

    Full Text Available PURPOSE: To present an alternative technique for reconstruction of musculocutaneous damages in the face transferring innervated subsegments(subunits of the latissimus dorsi flap for replacement of various facial mimetic muscles. METHODS: One clinical case of trauma with skin and mimetic muscles damage is described as an example of the technique. The treatment was performed with microsurgical transfer of latissimus dorsi muscle subunits. Each subunit present shape and dimensions of the respective mimetic muscles replaced. The origin, insertions and force vectors for the mimicmuscle lost were considered. Each subsegment has its own arterial and venous supply with a motor nerve component for the muscular unit. RESULTS: Pre and one year postoperative photos registration of static and dynamic mimic aspects, as well as digital electromyography digital data of the patients were compared. The transplanted muscular units presented myoeletric activity, fulfilling both the functional and cosmetic aspect. CONCLUSION: This technique seems to be a promising way to deal with the complex musculocutaneous losses of the face as well as facial palsy.

    Facioscapulohumeral muscular dystrophy (FSHD) is characterized by extremely variable degrees of facial, scapular and lower limb muscle involvement. Clinical and genetic determination can be difficult, as molecular analysis is not always definitive, and other similar muscle disorders may have overlapping clinical manifestations. Whole-body muscle MRI examination for fat infiltration, atrophy and oedema was performed to identify specific patterns of muscle involvement in FSHD patients (30 subjects), and compared to a group of control patients (23) affected by other myopathies (NFSHD). In FSHD patients, we detected a specific pattern of muscle fatty replacement and atrophy, particularly in upper girdle muscles. The most frequently affected muscles, including paucisymptomatic and severely affected FSHD patients, were trapezius, teres major and serratus anterior. Moreover, asymmetric muscle involvement was significantly higher in FSHD as compared to NFSHD patients. In conclusion, muscle MRI is very sensitive for identifying a specific pattern of involvement in FSHD patients and in detecting selective muscle involvement of non-clinically testable muscles. Muscle MRI constitutes a reliable tool for differentiating FSHD from other muscular dystrophies to direct diagnostic molecular analysis, as well as to investigate FSHD natural history and follow-up of the disease.

    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.

    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.

    2018-01-01

    Muscular dystrophy is defined as the progressive wasting of skeletal muscles that is caused by inherited or spontaneous genetic mutations. Next-generation sequencing has greatly improved the accuracy and speed of diagnosis for different types of muscular dystrophy. Advancements in depth of coverage, convenience, and overall reduced cost have led to the identification of genetic modifiers that are responsible for phenotypic variability in affected patients. These genetic modifiers have been postulated to explain key differences in disease phenotypes, including age of loss of ambulation, steroid responsiveness, and the presence or absence of cardiac defects in patients with the same form of muscular dystrophy. This review highlights recent findings on genetic modifiers of Duchenne and facioscapulohumeral muscular dystrophies based on animal and clinical studies. These genetic modifiers hold great promise to be developed into novel therapeutic targets for the treatment of muscular dystrophies. Muscle Nerve 57: 6-15, 2018. © 2017 Wiley Periodicals, Inc.

  12. Why is muscularity sexy? Tests of the fitness indicator hypothesis.

    Frederick, David A; Haselton, Martie G

    2007-08-01

    Evolutionary scientists propose that exaggerated secondary sexual characteristics are cues of genes that increase offspring viability or reproductive success. In six studies the hypothesis that muscularity is one such cue is tested. As predicted, women rate muscular men as sexier, more physically dominant and volatile, and less committed to their mates than nonmuscular men. Consistent with the inverted-U hypothesis of masculine traits, men with moderate muscularity are rated most attractive. Consistent with past research on fitness cues, across two measures, women indicate that their most recent short-term sex partners were more muscular than their other sex partners (ds = .36, .47). Across three studies, when controlling for other characteristics (e.g., body fat), muscular men rate their bodies as sexier to women (partial rs = .49-.62) and report more lifetime sex partners (partial rs = .20-.27), short-term partners (partial rs = .25-.28), and more affairs with mated women (partial r = .28).

    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

    Foraminal and extra-foraminal disc herniations comprise up to 11.7% of all lumbar disc herniations. Facetectomy, which had been the classic approach, is now recognized as cause of pain and instability after surgery. Otherwise, posterior lateral approaches through a trans-muscular or a para-muscular technique offer no significant damage to key structures for spinal stability. The surgical anatomy of these approaches has already been described, but they were not compared. In order to quantify the angle of vision towards the intervertebral foramen offered by each technique, 12 fresh cadavers were dissected and studied regarding these approaches. The angle presented by trans-muscular approach was wider in all studied lumbar levels. Surgery through the trans-muscular approach is performed with a better working angle, requiring a smaller resection of surrounding tissues. Therefore, minor surgical trauma can be expected. Our measurements support previously published data that point the trans-muscular approach as the best surgical option.

    More patients suffering with Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are presenting to perianesthesia settings for emergent and nonemergent treatment and care. A group of collaborative health care providers at Rush University Medical Center in Chicago developed a multidisciplinary DMD/BMD Task Force to study this disorder and create a set of guidelines to aid those engaging in the planning, execution of care, and recovery of this unique population in the perianesthesia setting. Attention to detail, well-executed preplanning, meticulous awareness of the patient, and prearranged implementation and intervention has proven to offset potential problems and complications and is the key to a successful perianesthesia period.

    OBJECTIVE: Duchenne muscular dystrophy (DMD) patients are often treated with glucocorticoids; yet their precise molecular action remains unknown. METHODS: We investigated muscle biopsies from nine boys with DMD (aged: 7,6±2,8 yrs.) collected before and after three months of deflazacort treatment...... into the molecular actions of glucocorticoids in DMD at the mRNA level, and we show that multiple regulatory pathways are influenced. This information can be important in the development of new treatments....

    The purpose of this study was to explore the prevalence, nature and scope of pain in adolescents with spinal muscular atrophy and Duchenne and Becker muscular dystrophy and whether the pain differs between diagnostic groups or between adolescents with different ambulation status. Furthermore to study the consequences of pain and to identify pain-exacerbating and pain-relieving factors. In a national survey, fifty-five adolescents with spinal muscular atrophy and dystrophinopathy completed a questionnaire assessing pain frequency, duration, location using a body map, intensity and discomfort using visual analogue scales, pain interference using a modified version of Brief Pain Inventory and factors exacerbating and relieving pain. Sixty-nine per cent of the adolescents reported pain during the past three months and 50% reported chronic pain. The pain prevalence did not differ significantly between diagnostic groups or between ambulators and non-ambulators. The average pain intensity was graded as mild and the worst pain as moderate. The pain typically occurred weekly, most frequently in the neck/back or legs. General activity and mood were the areas that were most affected by pain. Common pain-exacerbating factors were sitting, too much movement/activity and being lifted or transferred. Pain is a frequent problem in adolescents with spinal muscular atrophy and dystrophinopathy. The assessments used enable an understanding both of the nature and scope of pain and of the impact of pain in everyday life. The study highlights the importance of assessing pain in a systematic manner and offering an individual approach to interventions designed to reduce pain in this population.

    Primary skin fibroblast cultures were grown from forearm pinch skin biopsies obtained from 24 patients with Duchenne muscular dystrophy (DMD) and ten normal controls matched for sex and age. The first subcultures were grown for 7 days and incubated with L-( 3 H)-proline for 24 hours. Intracellular collagen incoption was significantly decreased (2.2 X) and extracellular collagen incorporation significantly increased (1.8 X) in fibroblast cultures from patients with DMD by both collagenase assay and polyacrylamide gel electrophoresis. The synthesis of noncollagen proteins showed low values from the DMD fibroblast cultures. The alterations in synthesis and secretion of collagen and noncollagen proteins were characteristic only for the log phase of DMD fibroblasts. (author)

    Full Text Available Duchenne muscular dystrophy (DMD is X-linked recessive hereditary disease. DMD gene mutations result in dystrophin deficiency, which causes not only muscle movement disorders but also scoliosis, cognitive dysfunction, urinary tract diseases, respiratory diseases and heart diseases. Most patients die in early adult for respiratory and circulatory failure. Early multidisciplinary therapies will significantly delay disease progression and improve patients' quality of life. However, DMD diagnosis and treatment exist significantly time delay now. In this study, we review the natural history of DMD, including motor, cognitive, respiratory and heart function, for improving DMD early recognition, diagnosis and treatment, so as to benefit DMD patients. DOI: 10.3969/j.issn.1672-6731.2015.05.004

    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.

  7. The Importance of Muscular Strength: Training Considerations.

    Science.gov (United States)

    Suchomel, Timothy J; Nimphius, Sophia; Bellon, Christopher R; Stone, Michael H

    2018-04-01

    This review covers underlying physiological characteristics and training considerations that may affect muscular strength including improving maximal force expression and time-limited force expression. Strength is underpinned by a combination of morphological and neural factors including muscle cross-sectional area and architecture, musculotendinous stiffness, motor unit recruitment, rate coding, motor unit synchronization, and neuromuscular inhibition. Although single- and multi-targeted block periodization models may produce the greatest strength-power benefits, concepts within each model must be considered within the limitations of the sport, athletes, and schedules. Bilateral training, eccentric training and accentuated eccentric loading, and variable resistance training may produce the greatest comprehensive strength adaptations. Bodyweight exercise, isolation exercises, plyometric exercise, unilateral exercise, and kettlebell training may be limited in their potential to improve maximal strength but are still relevant to strength development by challenging time-limited force expression and differentially challenging motor demands. Training to failure may not be necessary to improve maximum muscular strength and is likely not necessary for maximum gains in strength. Indeed, programming that combines heavy and light loads may improve strength and underpin other strength-power characteristics. Multiple sets appear to produce superior training benefits compared to single sets; however, an athlete's training status and the dose-response relationship must be considered. While 2- to 5-min interset rest intervals may produce the greatest strength-power benefits, rest interval length may vary based an athlete's training age, fiber type, and genetics. Weaker athletes should focus on developing strength before emphasizing power-type training. Stronger athletes may begin to emphasize power-type training while maintaining/improving their strength. Future research should

    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

    Mutations in the DMD gene result in Duchenne or Becker muscular dystrophy due to absent or altered expression of the dystrophin protein. The more severe Duchenne muscular dystrophy typically presents around ages 2 to 5 with gait disturbance, and historically has led to the loss of ambulation by age 12. It is important for the practicing pediatrician, however, to be aware of other presenting signs, such as delayed motor or cognitive milestones, or elevated serum transaminases. Becker muscular dystrophy is milder, often presenting after age 5, with ambulation frequently preserved past 20 years and sometimes into late decades. Copyright © 2015 Elsevier Inc.

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.

    1994-09-01

    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.

    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. This may propose a new concept of morphology of congenital hip dysplasia.

    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.

    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.

    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)

    Reinnervation of a free muscle graft by nerves from an adjacent intact muscle is called muscular neurotization. This paper investigates the mechanisms and stimuli responsible for muscular neurotization in the rat. Sternohyoid or sternomastoid muscles were transplanted as free muscle grafts to the ventral surface of an intact sternohyoid muscle (feeder muscle). After several weeks the graft and underlying feeder muscle were removed together, frozen, serially sectioned, stained, and carefully examined for the presence or absence of nerves. It was concluded from a series of experiments that in this model muscular neurotization is a form of nerve regeneration. In order for muscular neurotization to occur, it is necessary to have (1) injury to the nerves of the intact feeder muscle and (2) a pathway upon which the regenerating nerves may grow into the graft.

We focused on how physicians provide support to the mothers of children with Duchenne muscular dystrophy who have difficulty communicating about the condition with their child. The eligible participants were certified child neurologists of the Japanese Society of Child Neurology. Participants responded to questionnaires consisting of free descriptions of a vignette of a child with Duchenne muscular dystrophy and a mother. We analyzed 263 responses of the participants. We found 4 themes on advising mothers, involving encouraging communication, family autonomy, supporting family, and considering the child's concerns. These results provide a better understanding of the communication between physicians and family members who need help sharing information with a child with Duchenne muscular dystrophy. These findings will assist clinical practitioners in supporting families and the affected children throughout the course of their illness. © The Author(s) 2015.

    Full Text Available Duchenne muscular Dystrophy (DMD is an inherited disease caused by mutations in the dystrophin gene that disrupt the open reading frame, while in frame mutations result in Becker muscular dystrophy (BMD. Ullrich congenital muscular dystrophy (UCMD is due to mutations affecting collagen VI genes. Specific muscle miRNAs (dystromirs are potential non-invasive biomarkers for monitoring the outcome of therapeutic interventions and disease progression. We quantified miR-1, miR-133a,b, miR-206 and miR-31 in serum from patients with DMD, BMD, UCMD and healthy controls. MiR-1, miR-133a,b and miR-206 were upregulated in DMD, but unchanged in UCMD compared to controls. Milder DMD patients had higher levels of dystromirs than more severely affected patients. Patients with low forced vital capacity (FVC values, indicating respiratory muscle weakness, had low levels of serum miR-1 and miR-133b. There was no significant difference in the level of the dystromirs in BMD compared to controls. We also assessed the effect of dystrophin restoration on the expression of the five dystromirs in serum of DMD patients treated systemically for 12 weeks with antisense oligomer eteplirsen that induces skipping of exon 51 in the dystrophin gene. The dystromirs were also analysed in muscle biopsies of DMD patients included in a single dose intramuscular eteplirsen clinical trial. Our analysis detected a trend towards normalization of these miRNA between the pre- and post-treatment samples of the systemic trial, which however failed to reach statistical significance. This could possibly be due to the small number of patients and the short duration of these clinical trials. Although longer term studies are needed to clarify the relationship between dystrophin restoration following therapeutic intervention and the level of circulating miRNAs, our results indicate that miR-1 and miR-133 can be considered as exploratory biomarkers for monitoring the progression of muscle weakness

    Full Text Available The Ras superfamily of guanosine-triphosphate (GTP-binding proteins regulates a diverse spectrum of intracellular processes involved in inflammation and fibrosis. Farnesythiosalicylic acid (FTS is a unique and potent Ras inhibitor which decreased inflammation and fibrosis in experimentally induced liver cirrhosis and ameliorated inflammatory processes in systemic lupus erythematosus, neuritis and nephritis animal models. FTS effect on Ras expression and activity, muscle strength and fibrosis was evaluated in the dy(2J/dy(2J mouse model of merosin deficient congenital muscular dystrophy. The dy(2J/dy(2J mice had significantly increased RAS expression and activity compared with the wild type mice. FTS treatment significantly decreased RAS expression and activity. In addition, phosphorylation of ERK, a Ras downstream protein, was significantly decreased following FTS treatment in the dy(2J/dy(2J mice. Clinically, FTS treated mice showed significant improvement in hind limb muscle strength measured by electronic grip strength meter. Significant reduction of fibrosis was demonstrated in the treated group by quantitative Sirius Red staining and lower muscle collagen content. FTS effect was associated with significantly inhibition of both MMP-2 and MMP-9 activities. We conclude that active RAS inhibition by FTS was associated with attenuated fibrosis and improved muscle strength in the dy(2J/dy(2J mouse model of congenital muscular dystrophy.

    Research suggests that peer muscularity norms preferences are related to men's body image, but little information is known about how perceptions of specific peer group norms preferences are related to men's body image disturbances and specific health behaviors. This study investigated how men perceived the muscularity preferences of male, female, close, and distant peers and whether the perceptions of specific peer preferences were related to muscle dysmorphia and steroid use. Data on muscle dysmorphia and the perceptions of peer muscularity norms were collected from 117 male college students. Results indicated that men perceived distant and male peers as having the most exaggerated preferences for muscularity and that those perceptions were not an accurate reflection of their distant male peers' reported preferences. Results also indicated that perceptions of close female peer muscularity preferences were predictive of symptoms of muscle dysmorphia, but this relationship did not exist for other peer groups, suggesting that the perceptions of close female peer preferences may play a role in the development of muscle dysmorphia. No relationship was found between perceptions of peer muscularity preferences and steroid use. © The Author(s) 2015.

  1. Oxidative muscular injury and its relevance to hyperthyroidism.

    1990-01-01

    In experimental hyperthyroidism, acceleration of lipid peroxidation occurs in heart and slow-oxidative muscles, suggesting the contribution of reactive oxygen species to the muscular injury caused by thyroid hormones. This article reviews various models of oxidative muscular injury and considers the relevance of the accompanying metabolic derangements to thyrotoxic myopathy and cardiomyopathy, which are the major complications of hyperthyroidism. The muscular injury models in which reactive oxygen species are supposed to play a role are ischemia/reperfusion syndrome, exercise-induced myopathy, heart and skeletal muscle diseases related to the nutritional deficiency of selenium and vitamin E and related disorders, and genetic muscular dystrophies. These models provide evidence that mitochondrial function and the glutathione-dependent antioxidant system are important for the maintenance of the structural and functional integrity of muscular tissues. Thyroid hormones have a profound effect on mitochondrial oxidative activity, synthesis and degradation of proteins and vitamin E, the sensitivity of the tissues to catecholamine, the differentiation of muscle fibers, and the levels of antioxidant enzymes. The large volume of circumstantial evidence presented here indicates that hyperthyroid muscular tissues undergo several biochemical changes that predispose them to free radical-mediated injury.

    We quantitatively evaluated the muscular wastings of lower extremities in Duchenne muscular dystrophy (DMD) by computed tomography (CT). The subjects were 21 cases of DMD (an ambulant case and 20 wheelchair-ridden cases, ages ranging from 10 to 21 years old) and 4 control males. The CT scan was carried out at the mid-level between lesser trochanter and medial condyle of femur and the largest diameter level of lower leg. The density and the cross-sectional area of each muscle were measured on the CT image. The average CT number of normal muscle was varying from 40 to 60, as well as that of fat was -115. Then we calculated CT index of each muscle denoted as follows: CT index = [average CT number of muscle-(-115)] X(cross-sectional area of each muscle). The measurements of muscle strength and serum CK level were performed and their relationships to CT index were examined. The results were achieved as follows: 1) Wheelchair-ridden cases with DMD showed severe decrease in the average CT number and the CT index of each muscle with normal controls. With progression, the average CT number and the CT index were reduced. But gracilis muscle and sartorius muscle were relatively spared in comparison with other muscles. 2) There was positive correlation between the CT index and the muscle strength in triceps surae muscle, hamstrings muslce and quardriceps femoris muscle. 3) The CT index of whole thigh muscles and that of whole lower leg muscles were highly correlated to serum CK level. These results suggest that the quantitative analysis of muscle CT is an useful measurement for assessement of muscular wastings in DMD. (author)

    Generating human skeletal muscle models is instrumental for investigating muscle pathology and therapy. Here, we report the generation of three-dimensional (3D) artificial skeletal muscle tissue from human pluripotent stem cells, including induced pluripotent stem cells (iPSCs) from patients with Duchenne, limb-girdle, and congenital muscular dystrophies. 3D skeletal myogenic differentiation of pluripotent cells was induced within hydrogels under tension to provide myofiber alignment. Artificial muscles recapitulated characteristics of human skeletal muscle tissue and could be implanted into immunodeficient mice. Pathological cellular hallmarks of incurable forms of severe muscular dystrophy could be modeled with high fidelity using this 3D platform. Finally, we show generation of fully human iPSC-derived, complex, multilineage muscle models containing key isogenic cellular constituents of skeletal muscle, including vascular endothelial cells, pericytes, and motor neurons. These results lay the foundation for a human skeletal muscle organoid-like platform for disease modeling, regenerative medicine, and therapy development. Copyright © 2018 The Author(s).

    Spinal muscular atrophy (SMA) causes respiratory compromise that is difficult to assess in young children. The forced oscillation technique (FOT) is commercially available for children as young as 2 years of age and is nonvolitional. The aim of this study was to assess the usefulness of FOT in young children with SMA. Children with SMA aged resistance at 8 Hz (Rrs8) (mean z score, +0.66; SD, 1.34; P = .12) were abnormal. Four children performed spirometry. Linear relationships to Xrs8 exist: FVC (R2, 0.54), unassisted PCF (R2, 0.33), assisted PCF (R2, 0.43), and AHI (R2, 0.32). Over 12 months, Xrs8z score worsened (rate of change of +1.08, P change +0.51, P .05) was found between clinical characteristics and FOT values. FOT is feasible in young children with SMA, with abnormal values of reactance and resistance on grouped data, worsening over 12 months. Xrs8 is related to respiratory tests used to monitor progress in SMA (FVC, PCF, AHI). Further research on the value of FOT in managing individuals is warranted.

    Our purpose in this study was to better understand the muscular anatomy of the ventricular folds in order to help improve biomechanical modeling of phonation and to better understand the role of these muscles during phonatory and nonphonatory tasks. Four human larynges were decalcified, sectioned coronally from posterior to anterior by a CryoJane tape transfer system, and stained with Masson's trichrome. The total and relative areas of muscles observed in each section were calculated and used for characterizing the muscle distribution within the ventricular folds. The ventricular folds contained anteriorly coursing thyroarytenoid and ventricularis muscle fibers that were in the lower half of the ventricular fold posteriorly, and some ventricularis muscle was evident in the upper and lateral portions of the fold more anteriorly. Very little muscle tissue was observed in the medial half of the fold, and the anterior half of the ventricular fold was largely devoid of any muscle tissue. All 4 larynges contained muscle bundles that coursed superiorly and medially through the upper half of the fold, toward the lateral margin of the epiglottis. Although variability of expression was evident, a well-defined thyroarytenoid muscle was readily apparent lateral to the arytenoid cartilage in all specimens.

  6. Optimizing Bone Health in Duchenne Muscular Dystrophy

    Full Text Available Duchenne muscular dystrophy (DMD is an X-linked recessive disorder characterized by progressive muscle weakness, with eventual loss of ambulation and premature death. The approved therapy with corticosteroids improves muscle strength, prolongs ambulation, and maintains pulmonary function. However, the osteoporotic impact of chronic corticosteroid use further impairs the underlying reduced bone mass seen in DMD, leading to increased fragility fractures of long bones and vertebrae. These serious sequelae adversely affect quality of life and can impact survival. The current clinical issues relating to bone health and bone health screening methods in DMD are presented in this review. Diagnostic studies, including biochemical markers of bone turnover and bone mineral density by dual energy X-ray absorptiometry (DXA, as well as spinal imaging using densitometric lateral spinal imaging, and treatment to optimize bone health in patients with DMD are discussed. Treatment with bisphosphonates offers a method to increase bone mass in these children; oral and intravenous bisphosphonates have been used successfully although treatment is typically reserved for children with fractures and/or bone pain with low bone mass by DXA.

    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.

    Congenital choanal atresia is a rare abnormality characterized by unilateral or bilateral lack of patency of the posterior end of the nasal cavity. 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

    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.

Many reach adulthood and the population of adults with congenital heart disease is increasing and ageing. However, repair of congenital heart disease does not mean cure. Many adults with congenital heart disease encounter late complications. Late morbidity can be related to the congenital heart defect itself, but may also be the consequence of the surgical or medical treatment or longstanding alterations in hemodynamics, neurodevelopment and psychosocial development.

Biochemical, Vignos score, and genetic data were collected on 212 boys with dystrophinopathy. Results. Serum Crn level had a strong inverse correlation with Vignos score by simple correlation (r=-0.793 and partial correlation analysis after adjustment for age, height, and weight (r=-0.791; both P<0.01. Serum Crn level was significantly higher in patients with in-frame than out-of-frame mutations (Z=-4.716, P<0.01 and in Becker muscular dystrophy (BMD patients than Duchenne muscular dystrophy (DMD patients at ages 4, 5, 7, and 9 yr (all P<0.0125. After adjusting for age, height, and weight, BMD patients still had a significantly higher serum Crn level than DMD patients (β=7.140, t=6.277, P<0.01. Conclusions. Serum Crn level reflected disease severity and may serve as a supplemental index to distinguish DMD from BMD in clinical practice.

    Becker muscular dystrophy (BMD) was first described in 1955 and linked to the DMD gene in 1987. Compared to Duchenne muscular dystrophy (DMD), clinical onset of BMD usually occurs after the age of 12 and wheelchair is required after the age of 16. BMD is characterized by generalized weakness first affecting limb girdle muscles, hypertrophy of the calves and cardiomyopathy in males. Some patients have only mild symptoms such as cramps or elevated serum creatine kinases (SCK) throughout all their lives. SCK levels are usually elevated. Muscle biopsy (immunohistochemistry or immunoblotting) shows a dystrophic pattern with abnormal dystrophin staining. Diagnosis is confirmed by DMD gene sequencing. Deletions or duplications of one or several exons are identified in the majority of cases. A multidisciplinary approach is recommended for the care management of these patients with a particular attention to the cardiomyopathy, which is typically responsible for death but can be prevented by specific treatment. X-linked dilated cardiomyopathies linked to DMD gene are a phenotypic continuum of BMD. Some female carriers of DMD mutations exhibit clinical symptoms of variable severity, often milder and beginning later than in males. The cardiomyopathy is the most frequent feature that should be especially monitored in these patients. Genetic counselling should be systematically proposed. Copyright © 2015 Elsevier Masson SAS.

    Merosin deficient congenital muscular dystrophy 1A (MDC1A) results from mutations in the LAMA2 gene. We report 51 patients with MDC1A and examine the relationship between degree of merosin expression, genotype and clinical features. Thirty-three patients had absence of merosin and 13 showed some residual merosin. Compared to the residual merosin group, patients with absent merosin had an earlier presentation (<7days) (P=0.0073), were more likely to lack independent ambulation (P=0.0215), or require enteral feeding (P=0.0099) and ventilatory support (P=0.0354). We identified 33 novel LAMA2 mutations; these were distributed throughout the gene in patients with absent merosin, with minor clusters in exon 27, 14, 25 and 26 (55% of mutations). Patients with residual merosin often carried at least one splice site mutation and less frequently frameshift mutations. This large study identified novel LAMA2 mutations and highlights the role of immunohistochemical studies for merosin status in predicting clinical severity of MDC1A.

    We compare 1,5 T magnetic resonance (MR) image findings in 193 patients with congenital pituitary congenital insufficiency. One hundred and thirty nine of the MR studies were obtained in patients who had isolated growth hormone deficiency. Other fifth - four patients had multiple pituitary hormone deficiency. On MR images, normal anterior and posterior lobes of the pituitary glands can be clearly differentiated because the posterior lobe has a characteristic high intensity on TI-weighted images. In fifty-four patients, the high- intensity of the posterior lobe was not seen, but a similar high signal intensity was observed at the proximal stump in fifty-one patients. this high- intensity area is the newly formed ectopic posterior lobe, which also secrets anti-diuretic hormone just as the posterior lobe would. MR imaging can demonstrate the transection of the pituitary stalk and the formation of the ectopic lobe, revealing to be a useful diagnostic tool in the definition of the type of alteration in growth defects of endocrine origin.

    Many explorations have been done by our antecessors to find out about the congenital anomalies which might be caused by X-ray or γ-ray and experimental teratological researches have also been done, with some results. However, there have been less systematic studies on corpuscular radiation. Neutron ray is a radioactive ray no electrically-charged equally as photon (X-ray, γ-ray). With an equal dosage of it as photon's, its localized energy is high so that it is different in RBE, OER, etc. In heavy charged particle (proton ray, He ion, Ne ion, π-meson ray), there is the characteristic that the energy increases at around the deepest spot within the range rather than at the point of injection into a system, which is called Bragg peak. The type and energy of this radiation reflected in the uniqueness in energy distribution, in ionization density and in LET makes it the most important radioactive biological parameter. At this paper, we shall review the types of radioactive rays and discuss the congenital anomalies (teratogenecity) including the experimental results obtained by application of our proton ray.

    The computed tomography (CT) scan was performed on 91 Duchenne type muscular dystrophy (DMD) patients on the following four levels; (1) at the level of L3 vertebra, (2) 2-3cm above the symphysis pubica, (3) midposition of the thigh, (4) largest-diameter section of the lower leg. The CT of muscles common to most of the DMD patients were as follows: 1. Muscle atrophy: Muscle atrophy was shown as a reduction in the cross-sectional area of the muscles. Very mild muscle atrophy could be detected either by the clearly identified muscle border or by scattered low-density areas of so-called ''moth-eaten'' appearance within muscles. 2. Fat infiltration: The decrease in radio-density of muscles was interpreted as infiltration of fatty tissue. This type of density change was further classified into diffuse, streaked, cobblestone and salt-and-pepper patterns according to the spacial distribution of low-density areas. 3. Selectivity pattern: As the chronological sequence of DMD muscle degeneration is usually different among individual muscles, it may be seen, in some stages, that some of the synergistic muscles are still only slightly involved, while the others are quite severely atrophied with evident fat infiltration. In certain stages of the disease, most of the patients show relative preservation of particular muscles although they assumed a rounded shape. The most resistent muscle was musculus gracilis, followed by the musculus sartorius, musculus semitendinosus (and/or musculus semimembranosus) in that order. According to the severity of the CT changes, 86 of the 91 patients were classed into five stages from A1 to A5. Morphological stages (A1-A5) were well correlated to the functional disability stages by Ueda with a correlation factor of r=0.88. (J.P.N.)

    Duchenne muscular dystrophy (DMD) causes progressive respiratory muscle weakness. The aim of the study was to analyze the trend of a large number of respiratory parameters to gain further information on the course of the disease. Retrospective study. 48 boys with DMD, age range between 6 and 19 year old, who were followed in our multidisciplinary neuromuscular clinic between 2001 and 2011. Lung function, blood gases, respiratory mechanics, and muscle strength were measured during routine follow-up over a 10-year period. Only data from patients with at least two measurements were retained. The data of 28 patients were considered for analysis. Four parameters showed an important decline with age. Gastric pressure during cough (Pgas cough) was below normal in all patients with a mean decline of 5.7 ± 3.8 cmH2 O/year. Sniff nasal inspiratory pressure (SNIP) tended to increase first followed by a rapid decline (mean decrease 4.8 ± 4.9 cmH2 O; 5.2 ± 4.4% predicted/year). Absolute forced vital capacity (FVC) values peaked around the age of 13-14 years and remained mainly over 1 L but predicted values showed a mean 4.1 ± 4.4% decline/year. Diaphragmatic tension-time index (TTdi) increased above normal values after the age of 14 years with a mean increase of 0.04 ± 0.04 point/year. This study confirms the previous findings that FVC and SNIP are among the most important parameters to monitor the evolution of DMD. Expiratory muscle strength, assessed by Pgas cough, and the endurance index, TTdi, which are reported for the first time in a large cohort, appeared to be informative too, even though measured through an invasive method. © 2013 Wiley Periodicals, Inc.

    Proton NMR-CT (magnetic field strength 0.1 Tesla, resonant frequency 4.5 MHz) was performed in 10 normal females and 19 Duchenne muscular dystrophy (DMD) carriers. The mean age was 39 ± 12 years for the normal females and 42 ± 6 years for the DMD carriers. In DMD carriers, there were 4 definite, 4 probable, and 11 possible carriers. T 1 (spin-lattice relaxation time) image was obtained for a slice at the buttock, mid-thigh and calf levels respectively. T 1 values were measured for the medial portion of the gluteus maximus, the vastus lateralis of the quadriceps femoris, and the gastrocnemius. The bound water fraction (BWF) was calculated from Fullerton's equation based on the fast proton diffusion model. The following results were obtained: (1) In normal females, muscle T 1 value was highest in the gastrocnemius and lowest in the gluteus maximus. (2) In DMD carriers, T 1 values of the gluteus maximus and quadriceps femoris were significantly higher than those of the normal females. There was, however, no significant difference in T 1 value of the gastrocnemius between DMD carriers and normal females. (3) In DMD carriers, BWFs of the gluteus maximus and quadriceps femoris were significantly lower than those of the normal females. (4) In DMD carriers, no significant correlation was observed between the muscle T 1 values and the serum creatine phosphokinase values. Increased tissue water content in the lower parts of the body due to gravity is considered to be the primary cause of the high T 1 value in the gastrocnemius of normal females. The presence of the degenerating muscle fibers are presumed responsible for the high T 1 value and low BWF in the proximal muscles of DMD carriers. (author)

    Proton NMR-CT (magnetic field strength 0.1 Tesla, resonant frequency 4.5 MHz) was performed in 15 normal (NC) and 20 Duchenne muscular dystrophy (DMD) males. The age ranged from 3 to 47 years for the NC males, and 1 to 14 years for the DMD males. In the DMD group there were one subclinical stage, 4 stage 1, 6 stage 2, 4 stage 3, and 5 stage 5 or higher patients. T 1 (longitudinal relaxation) images were obtained for three slices at the buttock, midthigh, and calf levels. The T 1 values were measured for the medial portion of the gluteus maximus, the vastus lateralis of the quadriceps femoris, the adductors, the sartorius, the gracilis, and the gastrocnemius muscles. Bound water fraction (BWF) was calculated from Fullerton's equation based on the fast diffusion model. The following results were obtained: (1) In the NC group, muscle T 1 values declined gradually with maturation under the age of 10, and became constant beyond that. The average T 1 value was 280 ms for the age group between 3 and 6 years, 270 ms for 7 and 10 years, and 260 ms for those older than 10 years. (2) Muscle BWF increased with maturation in the NC group. (3) In the DMD group, T 1 values were initially higher than normal (300 ms), declined rapidly with the progress of the disease, and reached the same low level as the subcutaneous fat (190 ms). (4) This decrease of T 1 value in DMD was not uniform for all muscles, being most prominent in the gluteus maximus and least so in the sartorius and gracilis. (5) In the early stages of DMD, the BWF was lower than normal. (J.P.N.)

  12. Electrical stimulation superimposed onto voluntary muscular contraction.

    Electrical stimulation (ES) reverses the order of recruitment of motor units (MU) observed with voluntary muscular contraction (VOL) since under ES, large MU are recruited before small MU. The superimposition of ES onto VOL (superimposed technique: application of an electrical stimulus during a voluntary muscle action) can theoretically activate more motor units than VOL performed alone, which can engender an increase of the contraction force. Two superimposed techniques can be used: (i) the twitch interpolation technique (ITT), which consists of interjecting an electrical stimulus onto the muscle nerve; and (ii) the percutaneous superimposed electrical stimulation technique (PST), where the stimulation is applied to the muscle belly. These two superimposed techniques can be used to evaluate the ability to fully activate a muscle. They can thus be employed to distinguish the central or peripheral nature of fatigue after exhausting exercise. In general, whatever the technique employed, the superimposition of ES onto volitional exercise does not recruit more MU than VOL, except with eccentric actions. Nevertheless, the neuromuscular response associated with the use of the superimposed technique (ITT and PST) depends on the parameter of the superimposed current. The sex and the training level of the subjects can also modify the physiological impact of the superimposed technique. Although the motor control differs drastically between training with ES and VOL, the integration of the superimposed technique in training programmes with healthy subjects does not reveal significant benefits compared with programmes performed only with voluntary exercises. Nevertheless, in a therapeutic context, training programmes using ES superimposition compensate volume and muscle strength deficit with more efficiency than programmes using VOL or ES separately.

    Cardiac assessment was not done routinely in Duchenne (DMD) and Becker muscular dystrophy (BMD) patients in Northern region of England while evidence was gathering on progressive cardiomyopathy in these patients. We wanted to find out the prevalence, progression and clinical features of cardiac involvement in Duchenne and Becker muscular dystrophy. Methods: It is a retrospective review of clinical, electrocardiographic and echocardiographic assessments. The notes of 52 Duchenne and Becker muscular dystrophy patients were reviewed out of which 32 had DMD, 6 had Intermediate muscular dystrophy (IMD) and 14 had BMD. Prevalence of preclinical and clinically evident cardiac involvement was 88.4% in DMD and BMD patients. Sixty nine% of patients had clinically evident cardiac involvement but only four patients had cardiac symptoms in the form of palpitations, out of which two were due to respiratory dysfunction and others was due to cardiac failure. Clinical examination of the rest of all of the patients was unremarkable. Electrocardiogram was abnormal in 88.4% of patients. Conduction defects were found in 19.4% of patients. Echocardiogram was abnormal in 80.7% of patients but all were poor echo subjects including those who had normal echocardiogram. Though most patients were asymptomatic, a high percentage had evidence of preclinical and clinically evident cardiac involvement. So in all patients with Xp21 linked muscular dystrophy a routine baseline cardiac assessment should be done at the age of 10 years and reviewed after intervals of one to two years. (author)

    The presence of nonprogressive cognitive impairment is recognized as a common feature in a substantial proportion of patients with Duchenne muscular dystrophy. To investigate the possible role of mutations along the dystrophin gene affecting different brain dystrophin isoforms and specific cognitive profiles, 42 school-age children affected with Duchenne muscular dystrophy, subdivided according to sites of mutations along the dystrophin gene, underwent a battery of tests tapping a wide range of intellectual, linguistic, and neuropsychologic functions. Full-scale intelligence quotient was approximately 1 S.D. below the population average in the whole group of dystrophic children. Patients with Duchenne muscular dystrophy and mutations located in the distal portion of the dystrophin gene (involving the 140-kDa brain protein isoform, called Dp140) were generally more severely affected and expressed different patterns of strengths and impairments, compared with patients with Duchenne muscular dystrophy and mutations located in the proximal portion of the dystrophin gene (not involving Dp140). Patients with Duchenne muscular dystrophy and distal mutations demonstrated specific impairments in visuospatial functions and visual memory (which seemed intact in proximally mutated patients) and greater impairment in syntactic processing.

    Duchenne muscular dystrophy is the most common muscle disease found in male children. Currently, there is no effective therapy available for Duchenne muscular dystrophy patients. Therefore, it is essential to make a prenatal diagnosis and provide genetic counseling to reduce the birth of such boys. We report a case of preimplantation genetic diagnosis associated with Duchenne muscular dystrophy. The couple E.P.R., 38-year-old, symptomatic patient heterozygous for a 2 to 47 exon deletion mutation in DMD gene and G.T.S., 39-year-old, sought genetic counseling about preimplantation genetic diagnosis process. They have had a 6-year-old son who died due to Duchenne muscular dystrophy complications. The couple underwent four cycles of intracytoplasmic sperm injection (ICSI) and eight embryos biopsies were analyzed by polymerase chain reaction (PCR) for specific mutation analysis, followed by microarray-based comparative genomic hybridisation (array CGH) for aneuploidy analysis. Preimplantation genetic diagnosis revealed that two embryos had inherited the maternal DMD gene mutation, one embryo had a chromosomal alteration and five embryos were normal. One blastocyst was transferred and resulted in successful pregnancy. The other embryos remain vitrified. We concluded that embryo analysis using associated techniques of PCR and array CGH seems to be safe for embryo selection in cases of X-linked disorders, such as Duchenne muscular dystrophy.

    OBJECTIVE: Duchenne muscular dystrophy (DMD) patients are often treated with glucocorticoids; yet their precise molecular action remains unknown. METHODS: We investigated muscle biopsies from nine boys with DMD (aged: 7,6±2,8 yrs.) collected before and after three months of deflazacort treatment...... approaching normal values (p⟨0.05) following treatment (towards an increase; CDH15, C-MET, DLK1, FGF2, IGF1R, MYF5, MYF6, MYOD, PAX7; towards a decrease: CD68, MYH8, TNFα). Treatment reduced CK levels (p⟨0.05), but we observed no effect on muscle protein expression. CONCLUSIONS: This study provides insight...... and compared them to eight healthy boys (aged: 5,3±2,4 yrs.). mRNA transcripts involved in activation of satellite cells, myogenesis, regeneration, adipogenesis, muscle growth and tissue inflammation were assessed.

    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.

    The increasing prevalence of congenital heart disease can be attributed to major improvements in diagnosis and treatment. Cardiovascular magnetic resonance imaging plays an important role in the clinical management strategy of patients with congenital heart disease. The development of new cardiovascular magnetic resonance (CMR) techniques allows comprehensive assessment of complex cardiac anatomy and function and provides information about the long-term residual post-operative lesions and complications of surgery. It overcomes many of the limitations of echocardiography and cardiac catheterization. This review evaluates the role of cardiovascular magnetic resonance imaging modality in the management of subject with congenital heart disease (CHD). (authors)

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

    Primary congenital hypothyroidism is frequently seen endocrine disorder and one of the preventable cause of mental retardation. Aim of study was to evaluate the frequency of permanent/transient hypothyrodism, and to detect underlying reason to identfy any marker which carries potential to discriminate permanent/transient form. Forty eight cases older than 3 years of age, diagnosed as primary congenital hypothyroidism and started thyroxin therapy in newborn-period, and followed up between January 2007-June 2013 were included in the study. Thyroid hormon levels were evaluated and thyroid ultrasonography was performed in cases who are at the end of their 3 years of age, after 6 weeks of thyroxine free period. Thyroid sintigraphy was performed if serum thyroid-stimulating hormone was high (≥ 5 mIU/mL) and perchlorate discharge test was performed if uptake was normal or increased on sintigraphy. Cases with thyroid-stimulating hormone levels ≥ 5 mIU/mL were defined as permanent primary congenital hypothyroidism group and as transient primary congenital hypothyroidism group with normal thyroid hormones during 6 months. The mean age was 3.8±0.7 years. Mean diagnosis age was 16.6±6.5 days and 14 cases (29.2%) were diagnosed by screening program of Ministry of Health. There were 23 cases (14F, 9M) in permanent primary congenital hypothyroidism group and 12 (52.2%) of them were dysgenesis (8 hypoplasia, 4 ectopia), and 11 (47.8%) dyshormonogenesis. In transient primary congenital hypothyroidism group, there were 25 cases (17M, 8F). The mean thyroid-stimulating hormone levels at diagnosis were similar in two groups. The mean thyroxin dose in permanent primary congenital hypothyroidism group was significantly higher than transient group at the time of thyroxin cessation (2.1±0.7, 1.5±0.5 mg/kg/d, respectively, p=0.004). Thyroxin dose ≥1.6 mcg/kg/d was 72% sensitive and 69.6% specific for predicting permenant primary congenital hypothyroidism. Transient primary

    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 hernias are complex and life-threatening lesions that are not just anatomic defects of the diaphragm, but represent a complex set of physiologic derangements of the lung, the pulmonary vasculature, and related structures. Imaging plays an increasingly important role in the care of these infants. Prenatal sonography and MRI have allowed early and accurate identification of the defect and associated anomalies. These tools have also been the key to defining the degree of pulmonary hypoplasia and to predicting neonatal survival and need for aggressive respiratory rescue strategies. In the postnatal period, conventional radiography supplemented by cross-sectional imaging in selected cases can be very useful in sorting out the differential diagnosis of intrathoracic masses, in the detection of associated anomalies, and in the management of complications. Understanding the pathogenesis of diaphragmatic defects, the underlying physiologic disturbances, and the strengths and limitations of current imaging protocols is essential to the effective and accurate management of these complex patients.

    Full Text Available Objective. To determine if there is an unrecognized problem of congenital rubella syndrome (CRS in Haiti, a country without a national rubella immunization program. Methods. During March 2001 and June 2001, screening physicals were conducted on approximately 80 orphans at three orphanages in Haiti that accept disabled children. Children were classified as probable CRS cases based on established clinical criteria. Photo documentation of findings was obtained whenever possible. Results. Six children met the criteria for probable CRS. Using data from surrounding Caribbean countries and from the United States of America prior to rubella immunization, we estimated that there are between 163 and 440 new cases of CRS per year in Haiti. Conclusions. CRS exists in Haiti, but its presence is generally unrecognized. A national rubella immunization policy should be considered.

    Exercise is an essential part of the physical and mental health. However, many doctors and patients have a conservative attitude to participate in exercise in patients with congenital heart disease (CHD). Exercise in patients with CHD is a relatively new and controversial field. Taking into account the involvement of exercise in patients with CHD is likely to induce acute cardiovascular events and even sudden death; many doctors have a conservative attitude to participate in exercise in patients with CHD, leading to the occurrence of excessive self-protection. CHD has been transformed from the original fatal diseases into chronic diseases, medical treatment will also transform from the improvement of the survival rate to the improvement of the quality of life. It is still a problem that whether patients with CHD should participate in exercise and which kind of CHD should take part in exercise to improve the quality of life.

    Duchenne muscular dystrophy (DMD) and Spinal muscular atrophy (SMA) causes significant disability and progressive functional impairment. Readily available instruments that assess functionality, especially in advanced stages of the disease, are required to monitor the progress of the disease and the impact of therapeutic interventions. To describe the development of a scale to evaluate upper limb function (UL) in patients with DMD and SMA, and describe its validation process, which includes self-training for evaluators. The development of the scale included a review of published scales, an exploratory application of a pilot scale in healthy children and those with DMD, self-training of evaluators in applying the scale using a handbook and video tutorial, and assessment of a group of children with DMD and SMA using the final scale. Reliability was assessed using Cronbach and Kendall concordance and with intra and inter-rater test-retest, and validity with concordance and factorial analysis. A high level of reliability was observed, with high internal consistency (Cronbach α=0.97), and inter-rater (Kendall W=0.96) and intra-rater concordance (r=0.97 to 0.99). The validity was demonstrated by the absence of significant differences between results by different evaluators with an expert evaluator (F=0.023, P>.5), and by the factor analysis that showed that four factors account for 85.44% of total variance. This scale is a reliable and valid tool for assessing UL functionality in children with DMD and SMA. It is also easily implementable due to the possibility of self-training and the use of simple and inexpensive materials. Copyright © 2016 Sociedad Chilena de Pediatría.

    Full Text Available Congenital diaphragmatic hernia is a common congenital anomaly of uncertain etiology. Its association with multiple congenital anomalies in various organs is well recognized and antenatal radiological evidence of congenital diaphragmatic hernia warrants thorough evaluation to detect other anomalies, some of which can be life threatening. Rarely, heterotopic hepatic tissue is identified in the hernia, a rare pathological finding, exhibiting more than one macroscopic and microscopic characteristics, and always associated with cardiac congenital anomalies. Herein, we report a case of left-sided microscopic heterotopic hepatic tissue in a congenital diaphragmatic hernia in an infant with multiple cardiac congenital anomalies, but with preserved pericardium.

    To determine whether children who underwent surgery for congenital heart disease (CHD) are as fit as their peers. We studied 66 children (6-14 years) who underwent surgery for ventricular septal defect (n = 19), coarctation of aorta (n = 10), tetralogy of Fallot (n = 15), and transposition of great arteries (n = 22); and 520 healthy children (6-12 years). All children performed physical fitness tests: cardiorespiratory fitness, muscular strength, balance, flexibility, and speed. Metabolic score was assessed through z-score standardization using 4 components: waist circumference, blood pressure, blood lipids, and insulin resistance. Assessment also included self-reported and accelerometer-measured physical activity. Linear regression analyses with group (CHD vs control) as a predictor were adjusted for age, body mass index, physical activity, and parental education. Measured physical activity level, body mass index, cardiorespiratory fitness, flexibility, and total metabolic score did not differ between children with CHD and controls, whereas reported physical activity was greater in the CHD group than control group. Boys with CHD were less strong in upper muscular strength, speed, and balance, whereas girls with CHD were better in lower muscular strength and worse in balance. High-density lipoprotein was greater in boys and girls with CHD, whereas boys with CHD showed unhealthier glucose homeostasis. Appropriate physical fitness was achieved in children after surgery for CHD, especially in girls. Consequently, children with CHD were not at increased total metabolic risk. Lifestyle counseling should be part of every patient interaction. Copyright © 2017 Elsevier Inc. All rights reserved.

    Eight children representing a spectrum of clinical states of biopsy-proven Duchenne muscular dystrophy (DMD) underwent magnetic resonance (MR) scans to assess the degree of muscular involvement and disease progression. Five muscle groups (neck, shoulder girdle, pelvic girdle, thigh and calf) were evaluated. In each case, involved muscles were clearly demarcated. Image estimates of disease severity by degree of muscle involvement correlated well with clinical staging. In our experience MR is useful for assessment of disease stage, selection of appropriate muscles for biopsy and planning for courses of physical and rehabilitation therapy.

    Muscular involvement of sarcoidosis is rare and occurs in two forms:nodular and myopathic. In the nodular variety, lesions are long and extend along muscle fibers. Axial MR imaging reveals a star-shaped central structure of decreased signal intensity. Sagittal and coronal MR images show three stripes:an inner stripe of decreased signal intensity and outer stripes of increased signal intensity. Longitudinal sonography shows an echogenic inner stripe and hypoechoic outer stripes. We report a case of nodular- type muscular sarcoidosis in a 53-year-old man, describing the findings of MRI and ultrasonography

    Congenital factor VII (FVII) deficiency is a rare bleeding disorder with autosomal recessive inheritance. The present female patient was diagnosed with congenital FVII deficiency because of low hepaplastin test (HPT), although vitamin K was given. Heterozygous p.A191T mutation was detected in the peripheral blood, and the same mutation was also found in the mother and sister. To the best of our knowledge, this is the fourth reported case of p.A191T mutation of FVII in the literature and the first to be reported in Japan. FVII coagulation activity (FVII:C) in asymptomatic heterozygous carriers is mildly reduced. Therefore, some patients may not be accurately diagnosed with congenital FVII deficiency. In infants with low HPT without vitamin K deficiency, congenital FVII deficiency should be considered. © 2015 Japan Pediatric Society.

    Full Text Available Congenital asymmetric crying face is an anomalia caused by unilateral absence or weakness of depressor anguli oris muscle The major finding of the disease is the absence or weakness in the outer and lower movement of the commissure during crying. The other expression muscles are normal and the face is symmetric at rest. The asymmetry in congenital asymmetric crying face is most evident during infancy but decreases by age. Congenital asymmetric crying face can be associated with cervicofacial, musclebone, respiratory, genitourinary and central nervous system anomalia. It is diagnosed by physical examination. This paper presents a six days old infant with Congenital asymmetric crying face and discusses the case in terms of diagnosis and disease features.

    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.

    2018-06-01

    Full Text Available Purpose: Congenital ectropion uvea is a rare anomaly, which is associated with open, but dysplastic iridocorneal angles that cause childhood glaucoma. Herein, we present 3 cases of angle-closure glaucoma in children with congenital ectropion uvea. Observations: Three children were initially diagnosed with unilateral glaucoma secondary to congenital ectropion uvea at 7, 8 and 13 years of age. The three cases showed 360° of ectropion uvea and iris stromal atrophy in the affected eye. In one case, we have photographic documentation of progression to complete angle closure, which necessitated placement of a glaucoma drainage device 3 years after combined trabeculotomy and trabeculectomy. The 2 other cases, which presented as complete angle closure, also underwent glaucoma drainage device implantation. All three cases had early glaucoma drainage device encapsulation (within 4 months and required additional surgery (cycloablation or trabeculectomy. Conclusions and importance: Congenital ectropion uvea can be associated with angle-closure glaucoma, and placement of glaucoma drainage devices in all 3 of our cases showed early failure due to plate encapsulation. Glaucoma in congenital ectropion uvea requires attention to angle configuration and often requires multiple surgeries to obtain intraocular pressure control.

    A 1-year-old female Labrador retriever was referred with a few days history of haematic-like vulvar discharge. Physical examination, vaginal inspection and palpation did not reveal any remarkable finding. Transabdominal ultrasound showed echogenic fluid accumulation in the vagina suggesting haemato-pyocolpos. An exploratory laparotomy was performed: a well-delimited ectasic vagina was identified. Ovariohysterectomy and partial vaginectomy and vaginoplasty were performed to spay the bitch and to remove the ectasic vagina. Post-operative recovery and 12-month follow-up were uneventful. Clinical, morphological and histological findings were consistent with a congenital abnormality of the muscular layer of the vagina complicated by haemato-pyocolpos. The disorganization of the vaginal tunica muscularis may have acted as locus minoris resistentiae in the vaginal wall. The organ was dilated and atonic due to the gradual accumulation of physiological fluids complicated by an overgrowth of genital bacteria. This congenital disorder has to be taken into account as differential diagnosis of haemato-pyocolpos with vaginal discharge in young bitches. © 2015 Blackwell Verlag GmbH.

    A study of 17 muscle biopsies from patients with myasthenia gravis was done, using freshfrozen section and histochemistry tecnics. It was found 15 abnormal muscle biopsies. The most common abnormality were small dark angular fibers, excess of lipids droplets outside the muscle membrane, changes in fiber size and type II fiber atrophy. These findings suggested denervation in 11 biopsies, type II fiber atrophy in 7, linfocyte infiltration in 4, fiber necrosis with fagocitosis in 1 and 2 were normal. Was noted a direct correlation between the disease duration and the severity of the histological abnormality. Two patients had tymoma. Congenital myasthenia gravis, rheumatoid arthritis, intersticial hypertrophic neuritis, Hashimoto tireoiditis and concomitance of myasthenic syndrome was found once in different patients.

    Scintigraphy with indium-111 labelled antimyosin has an established role in the evaluation of cardiac muscle damage. This antibody has been shown to cross-react with myosin in skeletal muscle. We therefore studied the usefulness of this method for the detection of skeletal muscle lesions in rhabdomyolysis, myositis and hereditary muscular dystrophies. All nine patients with rhabdomyolysis had focal uptake of antimyosin antibody which correlated with the clinical findings of soft tissue damage. However, a number of symptomless lesions were also detected by immunoscintigraphy. In rhabdomyolysis the target to non-target uptake ratios varied from 1.3 to 7.6. Diffuse uptake of antibody in skeletal muscle was observed in all three patients with polymyositis-dermatomyositis and in 12 out of 13 patients with muscular dystrophies. In myositis the intensity of antibody accumulation correlated reasonably well with the magnitude of oedema detected by magnetic resonance imaging (MRI). Most patients with Becker type or non-X-chromosomal muscular dystrophies showed slight or moderate uptake of antibody, mainly in the lower extremities. In these patients more antibody accumulated in the calves than in the thighs, whereas the findings on MRI were more prominent in the thighs than in the calves, presumably because of the better preserved muscle bulk in the calves. We conclude that antimyosin scintigraphy can be used for the detection of muscle lesions not only in acquired muscle diseases but also in hereditary muscular disorders, and that immunoscintigraphy provides information on muscle disease activity not obtainable with MRI.

    Full Text Available Jennifer G Andrews, Richard A Wahl Department of Pediatrics, University of Arizona, Tucson, AZ, USA Abstract: Duchenne muscular dystrophy (DMD and Becker muscular dystrophy (BMD are life-limiting and progressive neuromuscular conditions with significant comorbidities, many of which manifest during adolescence. BMD is a milder presentation of the condition and much less prevalent than DMD, making it less represented in the literature, or more severely affected individuals with BMD may be subsumed into the DMD population using clinical cutoffs. Numerous consensus documents have been published on the clinical management of DMD, the most recent of which was released in 2010. The advent of these clinical management consensus papers, particularly respiratory care, has significantly increased the life span for these individuals, and the adolescent years are now a point of transition into adult lives, rather than a period of end of life. This review outlines the literature on DMD and BMD during adolescence, focusing on clinical presentation during adolescence, impact of living with a chronic illness on adolescents, and the effect that adolescents have on their chronic illness. In addition, we describe the role that palliative-care specialists could have in improving outcomes for these individuals. The increasing proportion of individuals with DMD and BMD living into adulthood underscores the need for more research into interventions and intracacies of adolescence that can improve the social aspects of their lives.

    2012-01-01

    Full Text Available Common metabolic and endocrine alterations exist across a wide range of muscular dystrophies. Skeletal muscle plays an important role in glucose metabolism and is a major participant in different signaling pathways. Therefore, its damage may lead to different metabolic disruptions. Two of the most important metabolic alterations in muscular dystrophies may be insulin resistance and obesity. However, only insulin resistance has been demonstrated in myotonic dystrophy. In addition, endocrine disturbances such as hypogonadism, low levels of testosterone, and growth hormone have been reported. This eventually will result in consequences such as growth failure and delayed puberty in the case of childhood dystrophies. Other consequences may be reduced male fertility, reduced spermatogenesis, and oligospermia, both in childhood as well as in adult muscular dystrophies. These facts all suggest that there is a need for better comprehension of metabolic and endocrine implications for muscular dystrophies with the purpose of developing improved clinical treatments and/or improvements in the quality of life of patients with dystrophy. Therefore, the aim of this paper is to describe the current knowledge about of metabolic and endocrine alterations in diverse types of dystrophinopathies, which will be divided into two groups: childhood and adult dystrophies which have different age of onset.

    Full Text Available A dismorfia muscular tem sido identificada tanto em homens quanto em mulheres, provocando alterações da perceção da autoimagem e prejuízos socioculturais, e na saúde e bem-estar dos indivíduos. Nesse sentido, o objetivo deste estudo é analisar os aspetos socioculturais, psicológicos e o uso de recursos ergogênicos relacionados à dismorfia muscular, bem como, identificar os riscos promovidos pelo transtorno. Participaram 20 indivíduos, inscritos na rede mundial de computadores. Utilizou-se um questionário para coleta de dados e a análise documental para interpretação das respostas. Os resultados demonstram que as preocupações com a imagem corporal geram insegurança social, baixa autoestima e sentimentos de inferioridade, que seriam resolvidos se a pessoa tivesse corpos belos e fortes. A dismorfia muscular pode aumentar o risco de uso dos esteroides anabolizantes e o uso indiscriminado de suplementos alimentares. Conclui-se que a dismorfia muscular causa sofrimentos e prejuízos psicológicos, socioculturais e, desse modo, compromete a saúde das pessoas.

    2016-01-15

    Identification of a systemically acting and universal small molecule therapy for Duchenne muscular dystrophy would be an enormous advance for this condition. Based on evidence gained from studies on mouse genetic models, we have identified tyrosine phosphorylation and degradation of β-dystroglycan as a key event in the aetiology of Duchenne muscular dystrophy. Thus, preventing tyrosine phosphorylation and degradation of β-dystroglycan presents itself as a potential therapeutic strategy. Using the dystrophic sapje zebrafish, we have investigated the use of tyrosine kinase and other inhibitors to treat the dystrophic symptoms in this model of Duchenne muscular dystrophy. Dasatinib, a potent and specific Src tyrosine kinase inhibitor, was found to decrease the levels of β-dystroglycan phosphorylation on tyrosine and to increase the relative levels of non-phosphorylated β-dystroglycan in sapje zebrafish. Furthermore, dasatinib treatment resulted in the improved physical appearance of the sapje zebrafish musculature and increased swimming ability as measured by both duration and distance of swimming of dasatinib-treated fish compared with control animals. These data suggest great promise for pharmacological agents that prevent the phosphorylation of β-dystroglycan on tyrosine and subsequent steps in the degradation pathway as therapeutic targets for the treatment of Duchenne muscular dystrophy. © The Author 2015.
