Ragged-red fibers and complex I deficiency in a neonate with arthrogryposis congenita.

We describe a neonate with hypotonia, weakness, early death owing to respiratory failure, and a severe form of arthrogryposis multiplex congenita. Postmortem studies revealed numerous ragged-red fibers and central nervous system abnormalities consistent with a mitochondrial disease. No NADH:ubiquinone-1 oxidoreductase (complex I) activity could be detected in skeletal muscle. These findings suggest that mitochondrial cytopathies can be associated with arthrogryposis multiplex congenita and should therefore be sought in neonates presenting with severe arthrogryposis.

Arthrogryposis multiplex congenita and pituitary ectopia. A case report.

We report a patient with a form of arthrogryposis multiplex congenita who developed seizures at 4 months of age that proved to be hypoglycemic. Further evaluation of the etiology of hypoglycemia led to the discovery of partial anterior hypopituitarism, with normal posterior pituitary function. Neuroimaging revealed an ectopic neurohypophysis with very small anterior pituitary, the presumed anatomic basis for his endocrine dysfunction. A chance association between the pituitary ectopia and the arthrogryposis cannot be ruled out. However, it is more likely that in the present patient a common genetic mechanism may be the basis for both the arthrogryposis and the pituitary dysfunction.

Arthrogryposis and multicystic encephalopathy after acute fetal distress in the end stage of gestation.

The natural history of the rare association "multicystic encephalopathy-arthrogryposis" was traced in a fetus carefully followed after artificial insemination. The fetus exhibited normal viability and brain morphology up to the 32nd week. At 36 weeks, active movements diminished and at 37 weeks, hydramnios and signs of fetal distress led to cesarean section. The infant presented with severe arthrogryposis of the limbs and spine, but not with the other elements of a long-lasting akinesia. US showed multicystic encephalopathy. Both the clinical and the neuropathological findings established that multicystic encephalopathy was neither the cause nor the sequential consequence of the fetal akinesia, but the result of a recent diffuse, acute malacic process that also involved the anterior horn cells. Acute fetal distress, responsible for major ischemic damage to CNS but compatible with fetal survival, remains an obscure condition which allows for the development of severe arthrogryposis in a few weeks.

A family with autosomal dominant distal arthrogryposis multiplex congenita and brown syndrome.

Arthrogryposis multiplex congenita is a heterogeneous condition found in a number of different disorders and characterized by congenital joint contractures. We describe typical signs of congenital Brown syndrome (inability to elevate the affected eye actively or passively in full adduction) in three relatives with distal arthrogryposis multiplex congenita. We found a thickening of the superior oblique muscles in these patients with pain and increased intraocular pressure in upgaze. The pathogenesis of clinical and morphological findings is discussed. The association of Brown syndrome with distal arthrogryposis multiplex congenita has not been previously reported and provides us with an important point of reference in the understanding of both syndromes.

Arthrogryposis multiplex congenita: a report of two cases.

Arthrogryposis multiplex congenita refers to a group of birth defects characterised by multiple joint contractures. The syndrome is caused by neuropathic disease, myopathic disease, or any other cause of decreased fetal joint mobility. Multiple and usually symmetric joint abnormalities with associated muscular and soft tissue hypoplasia are noted at birth. A variety of associated congenital anomalies affecting many organ systems are frequently found. Ocular and orbital findings have been described in patients with arthrogryposis but corneal disease has only rarely been reported. We present corneal findings in two patients with arthrogryposis and discuss the implications for disease pathogenesis. Previous ophthalmologic reports are also reviewed.

Arthrogryposis following maternal hypotension.

A case of arthrogryposis multiplex congenita is described, in which the pregnancy had been complicated by a prolonged hypotensive period on the 86th day of gestation. The similarity in pathological findings between ischaemic myelopathy and arthrogryposis suggest that maternal hypotension was an aetiological factor in this infant's arthrogryposis.

Epileptic seizures, arthrogryposis, and migrational brain disorders: a syndrome?

INTRODUCTION: Arthrogryposis multiplex congenita (AMC) may be associated with multiple developmental defects. In some severely affected newborns with AMC, autopsy studies have suggested a common mechanism of malmigration at the spinal and cerebral levels. To our knowledge, a constellation of arthrogryposis, epileptic seizures, and brain migrational anomalies in adult patients has not previously been described in a clinical material. MATERIAL AND METHODS: Six consecutive adult patients with arthrogryposis multiplex congenita and epileptic seizures form the basis of the present study. Five patients had joint contractures and reduced muscle volume restricted to the lower extremities, whereas one patient had predominantly upper extremity affection. They were studied with magnetic resonance imaging (MRI), EEG, EMG, a neuropsychological test battery, and chromosome analysis. RESULTS: Four of them had clear evidence of migrational brain disorders, demonstrated by MRI, in three of them roughly corresponding to the focal epileptiform EEG activity. Five of the patients had partial seizures, whereas one only had generalized tonic-clonic seizures. The MRI findings included polymicrogyria, pachygyria, and fused schizencephaly. Four had neurogenic EMG changes, one had myopathic EMG features, and one had an unremarkable EMG pattern in affected muscles. All patients with demonstrable migrational disorders showed abnormal neuropsychological features. Three patients were mentally retarded. A chromosome abnormality in the form of a ring chromosome 18 was present in one patient. CONCLUSION: We suggest that AMC, epileptic seizures, and migrational brain disorders may form the integral parts of a hitherto undescribed syndrome in adults. A wide-spread defect in neuronal migration along the entire neural axis may be the underlying mechanism of the cerebral and the peripheral symptoms.

Neurogenic arthrogryposis multiplex congenita: clinical and muscle biopsy findings.

Thirteen cases of arthrogryposis multiplex congenita without evidence of spinal muscular atrophy, congenital muscular dystrophy, or structural myopathy were reviewed. Family history, consanguinity, pregnancy, delivery, number and severity of contractures, and outcome were evaluated. Laboratory investigations had been performed and a biopsy of muscle from an affected limb had been examined histochemically and by electron microscopy. Five biopsies showed fiber type 1 predominance and three had type 2 predominance. Patterns of fiber-type predominance may have resulted from altered neural influence leading to impaired maturation of type 1 or 2 motor units. Nine patients had been followed up for 3-8 years. Two were still not walking at age 8 years. For the 6 who were walking, the mean age at ambulation was 4.7 years. There was no deterioration in power. Muscle biopsy is recommended in arthrogryposis multiplex congenita. Identification of a probable neurogenic arthrogryposis multiplex congenita is important because the condition is not progressive and is apparently not transmitted genetically.

Interscalene brachial plexus block for shoulder surgery in a patient with arthrogryposis multiplex congenita.

A five-year-old child with severe arthrogryposis multiplex congenita and malnutrition underwent surgery for chronic osteomyelitis of the head of the left humerus. The child had typical features of arthrogryposis multiplex congenita, including a difficult airway. Propofol was used for induction and maintenance. Spontaneous respiration was maintained with a nasal airway. Analgesia was provided with an interscalene brachial plexus block placed using a nerve stimulator. No opioid was given. The child had an uneventful recovery with good postoperative analgesia. The anaesthetic implications of arthrogryposis multiplex congenita are discussed.

Long-term survival in a child with arthrogryposis multiplex congenita and spinal muscular atrophy.

Spinal muscular atrophy type 0 is a severe form of spinal muscular atrophy that is usually fatal in the first months of life. These children present with arthrogryposis multiplex congenita and respiratory compromise. We describe a child with spinal muscular atrophy and arthrogryposis multiplex congenita who has had a much better course and is alive without ventilator support at age 6 years. This case illustrates that the prognosis for spinal muscular atrophy and arthrogryposis multiplex congenita cannot always be predicted with certainty.

Arthrogryposis due to infantile neuronal degeneration associated with deletion of the SMNT gene.

To determine whether SMNT deletion may be associated with arthrogryposis, we tested DNA extracted from paraffin blocks for deletion of SMNT (exons 7 and 8). Analysis of the DNA showed an SMNT deletion in two of four infants with neurogenic arthrogryposis. In addition to loss of anterior horn cells, patients with SMNT deletion had degeneration of central sensory neurons in Clarke's column and the thalamus. Although one of the patients with no deletion also had cortical pathology, clinical and pathologic characteristics of the two patients without deletion were otherwise similar to the two patients with deletion. Arthrogryposis and degeneration of sensory neurons may be associated with deletion of SMNT.

The 1960s epidemic of arthrogryposis multiplex congenita: a survey from the United Kingdom, Australia and the United States of America.

Arthrogryposis multiplex congenita is believed to be a specific clinical entity which is aetiologically unrelated to the "arthrogryposis-like" deformities of known neurological diseases such as myelomeningocele and myelodysplasia. The observation that the condition appeared to be three times as common in Melbourne, Australia, as in four centres in the United Kingdom (Wynne-Davies and Lloyd-Roberts 1976), prompted this survey of 132 patients: 73 from the United Kingdom, 34 from Australia and 25 from Wilmington, Delaware, USA. The survey aimed to established the same criteria for diagnosis in the three countries and to search for prenatal and genetic aetiological factors. It was shown that all centers treated more newborn children with this disorder during the 1960s than either before or after that period. All cases were sporadic and there was no family association with talipes equinovarus, congenital dislocation of the hip or hereditary neuromuscular disease. "Environmental" findings from all three centers were similar and it was concluded that arthrogryposis multiplex cogenita is a non-genetic disease of early pregnancy, associated with a variety of unfavourable intra-uterine factors. In addition, an unknown but possibly viral environmental agent may have been present to a significant extent only during recent decades and is now declining.

Multiple congenital contractures (congenital multiple arthrogryposis).

Arthrogryposis, is the occurrence of joint contractures of variable etiology that start prenatally. Arthrogryposis may result from neurologic deficit, neuromuscular disorders, connective tissue abnormalities, amniotic bands, [figure: see text] or fetal crowding. Arthrogryposis may result from no apparent hereditary causes (neuropathic, for example) or may be the result of hereditary factors (myopathic form, for example). Ultrasound diagnosis depends on observation of scant or absent motion of fetal extremities. Prognosis depends on the specific etiology of the contractures.

[Arthrogryposis multiplex congenita--a rare congenital stiff joints syndrome].

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

[Contribution to the problem of Arthrogryposis multiplex (author's transl)].

A case of Arthrogryposis multiplex appearing after birth and of no characteristical course is described. It is shown that in respect to existing works for diagnosis of Arthrogryposis multiplex the insufficiency of the hitherto existing valid diagnostic criterions is obvious. This especially because the pathogenesis of Arthrogryposis multiplex is unknown. Trying to look for the condition of the connective tissue of our patient, it was found that the collagen of skin shows a young matter of polymerisation and a nearly correlating electron microscopical picture.

[Ilizarov technique for correcting flexion deformity of the knee of arthrogryposis multiplex congenita].

OBJECTIVE: To study the methods and effects of Ilizarov distraction technique in treating the flexion deformity of the knee of arthrogryposis multiplex congenita. METHODS: Between August 1998 and February 2003, 6 patients (10 knees) with the arthrogryposis multiplex congenita were treated, 4 patients in double knees, 5 males, 1 female, mean age 8 years and 2 months, ranged from 3 years and 7 months to 13 years. The preoperative flexion degree was averagely 51 degrees. The patients accompanied 13 other parts malformation of limbs. The modified Ilizarov distraction apparatus of the knee was used. While installing the apparatus in the operation, the knees should be kept in the of location of maximum extension, the center of joint hinges on the apparatus should be placed towards the rotatory center of the knee, two groups of 2 mm K-wires were passed through the femur and tibia around the knee, who were fixed on the proximal and distal rings. Distraction was started after the surgical procedure 5 days via rotating the threaded rods at the posterior of the knee, at an average of 2 to 3 mm per day, at the first week, after 2 weeks with the rate modified to 2 mm per day, up to the knee extended to 0 degrees. The accompanied deformities of the hip and/or the foot might be corrected at the same time or next time. The average duration of the distraction was 37 days (23-48 days). During the correction all limbs might undergo weight. After 2 weeks at the end of distraction the fixator was removed and the patients could walk by a long-leg brace. RESULTS: Ten knees with the flexion contracture were sufficiently corrected without severe complications. Nine knees of all were followed up at an average time of 1 years and 3 mouths, no recurrence of the deformity was seen in all patients, their function of walk was significantly improved. CONCLUSIONS: Ilizarov technique is a simply, safe and effective method for managing the flexion deformity of the knee of the arthrogryposis multiplex congentia. The procedure is conformable to the biological theories and microsurgical principles.

A retrospective study of pregnancy complications among 828 cases of arthrogryposis.

828 cases with multiple congenital contractures (arthrogryposis) were categorized and histories were reviewed to identify pregnancy complications. 53.0% of cases had a specified diagnosis or known cause and no diagnosis was found for 47.0% of which 27.2% were though to probably have a genetic basis and 19.8% were of unknown etiology. Our data provides no evidence to support the suggestion that arthrogryposis is frequently a result of environmental or structural causes including uterine structural anomaly, intra-uterine infection, etc. Normal frequencies of bleeding, hormone treatment during gestation, amniotic fluid leakage, uterine anomaly, maternal illness, and maternal and paternal age were noted. Apparent, increased frequencies of twinning, severe nausea, polyhydramnios and oligohydramnios were observed. In particular, the frequency of polyhydramnios was dramatically increased among lethal cases (vs survivors) and thus, polyhydramnios appears to be a poor prognostic sign when associated with decreased fetal movement. Large case control studies with complete pregnancy histories are needed to confirm these results and to definitively identify pregnancy complications that are useful "flags" to indicate decreased fetal movement in utero and thus, aid in the identification of primary causes of arthrogryposis.

Hydrops amnii in sheep associated with hydranencephaly and arthrogryposis with wesselsbron disease and rift valley fever viruses as aetiological agents.

During the 1974/75 lambing season numerous reports were received from various parts of the Republic of South Africa and South West Africa of severe abdominal distension in ewes after vaccination with the attenuated Rift Valley fever and/or attenuated Wesselsbron disease vaccine. The ewes were vaccinated at different stages of gestation in spite of recommendations to the contrary, the syndrome being especially obvious in ewes immunized with one or both of these vaccines during the first trimester of pregnancy. In some of the flocks hydrops amnii was recorded in as many as 15% of the ewes. Many of the ewes so affected showed a prolonged gestation of up to 6-7 months and, towards the end of gestation, were unable to rise or walk. They eventually died of ketosis, hypostatic pneumonia and complications due to dystocia. The foetuses examined were malformed and larger than normal with a mass of 3,6-6,7 kg. They usually showed arthrogryposis, brachygnathy inferior, hydranencephaly, hypoplasia or segmental aplasia of the spinal cord and neurogenic muscular atrophy. The amnion contained 8,0-18,0 1 of amniotic fluid, the endometrium was oedematous, and cystic tube-like dilatations, 1-10 mm in diameter, filled with a clear fluid, were scattered in the endometrium. No definite conclusions as to the aetiology of the syndrome could be drawn from serological tests performed on the ewes, lambs or foetuses. Preliminary experimental work confirmed previous observations that the attenuated Wesselsbron disease vaccine virus is responsible for this syndrome and that the wild-type virus is also implicated. In addition, the attenuated Rift Valley fever vaccine virus was found to the responsible for arthrogryposis and hydranencephaly without hydrops amnii and for micrencephaly and arthrogryposis associated with hydrops amnii in the ewe.
