A previously unrecorded nervous disease in pigeons was investigated. The disease, characterized by paresis, paralysis of the extremities, head-shaking, and torticollis, is contagious and spreads slowly. The mortality rate of affected pigeons was very high. The disease appeared to spread among pigeon flocks in spring and summer. The predominant gross change in most cases examined was congestion of the visceral organs. Some cases had grayish spots on the pancreas and kidneys. The histologic changes are characterized by neuronal and myelin degeneration with mononuclear cell infiltration and perivascular cuffing. Degeneration of the parenchyma and marked congestion are prominent in the visceral organs. The causal agent, found to be a virus, produced pock lesions on chorioallantoic membranes of developing chick embryos and failed to aagglutinate chicken RBCs. Antisera against Newcastle disease virus and avian encephalomyelitis virus did not neutralize the isolated virus. The virus produced typical signs in experimentally inoculated pigeons.

The authors report the follow-up results of forty-three patients operated on for myogenic torticollis between 1965 and 1975. The surgical treatment consisted of distal tenotomy in eight cases, distal and proximal tenotomy in twenty-three cases, tenomyomectomy in eight cases. The results were subdivided into three groups: excellent twenty-two, (57 per cent); good , fourteen (38 per cent); poor, two (five per cent). The most interesting finding that emerged was the association of paralysis of the trapezius muscle with myogenic torticollis: this was observed in six cases, three after and three before operation. Preoperative investigations, including an EMG test and confirmation at operation, appeared to show that the paralysis was secondary to compression of the accessory nerve in its passage through the sternocleidomastoid muscle. Neurolysis, performed in three cases, led to recovery of the paralysis. Compression of the accessory nerve is slowly progressive, and paralysis or paresis of the trapezius muscle therefore occurred late. In fact, the patients who presented with both lesions were well beyond infancy. The authors emphasize the importance of being aware of the association of this lesion with myogenic torticollis so that operation for the latter may complemented by neurolysis of the accessory nerve.

Three pedigrees are described in which 28 living siblings suffered from a benign myopathy. The first symptoms were observed around the fifth year of life. The proximal muscles were more involved than the distal muscles, the extensors more than the flexors. Due to a marked paresis of the extensor digitorum communis muscles 22 patients showed a flexion contracture of the interphalangeal joints of the last four fingers. In addition 20 patients showed a flexion contracture of the elbows and 12 patients had a plantar flexion contracture of the ankles. A high incidence of congenital torticollis was found. The histopathological features were non-specific and remarkably uniform and consisted of a marked variation in muslce fibre diameter and a very marked increase of fatty tissue. Light-microscopy and electronmicroscopy did not show any specific structural changes. There was normal distribution of type I and type II fibres, without type-grouping or preferential atrophy of one of the fibre types. Lobulated type I fibres were found in 6 out of 12 biopsies. Post-mortem study of one case did not show any convincing features of a neurogenic disorder. As no relationship could be found between the siblings of the 3 pedigrees as far back as the beginning of the eighteenth century, this myopathy seemed to be a new nosological entity.

The author discussed the increase in the frequency of traumatic paralyses of the ocular muscles, and reported 6 cases of inferior oblique muscle paresis caused by local blunt or sharp traumas (haematoma, contusion, rupture, incarceration) and one case of traumatic Brownian pseudo-paralysis. The localisation of the injuries in 3 cases was on the inferior temporal part and in the other 3 cases on the superior part of the bulbar conjunctiva. Atypical horizontal deviation and characteristic vertical deviation, torsion and torticollis were observed in the majority of cases. One patient recovered spontaneously. 3 patients became asymptomatic after correction by prisms and one after recession of contralateral superior rectus muscle. The symptoms remained unchanged in the case of a "blow out" fracture (in spite of operation) and a Brown's syndrome (without treatment).

A group of 2205 operations of strabismus in the course of 12 years reveals a clear predominance of operations of dynamic strabismus (94%), as compared with surgery of paralytic strabismus and ocular torticollis on account of nystagmus (6%). This fact provides evidence of a marked ratio of a non-paralytic aetiology of strabismus in the child population. In esotropia, the most frequent type of strabismus, the authors consider as most suitable the technique of weakening of the inner rectus muscles by a dosed elongation according to Gonin-Hollwich, as compared with the classical retroposition of this muscle. In exotropia the authors recommend reinforcing operations only or in combination with a weakening operation of the rectus muscles. The gradual development of application of the technique of surgery of the hyperfunctional lower oblique muscle is in favour of treble partial myotomy (elongation). They operate paretic strabismus when the IIIrd, IVth, VIth nerve are affected and supranuclear paresis of the levators by a complex procedure incl. transposition operations of the functional muscles. The authors operate ocular torticollis after a careful analysis of the congenital nystagmus, using special techniques on the rectus and oblique muscles which adjust the position of the head and bulbs.

Intramuscular injections of botulinum toxin (Botox) are followed by a dose-dependent focal paresis which can be used to treat several focal movement disorders. Botox injections are recommended as effective for the treatment of blepharospasm, hemifacial spasm, and cervical dystonia (torticollis). Focal dystonias elsewhere (for example, writer's cramp) can often be treated with similar success. Others, such as oromandibular dystonia, are more difficult to treat. In the case of more generalized dystonias, some focal muscle spasms can be treated with success by local intramuscular injections. New indications are still being investigated, for example in focal tremors and spasticity. Side effects are in general slight and disappear at the end of toxin effect. In general, it is necessary to repeat the injections after a couple of months, due to a cessation of effect after regrowth of nerve terminals. New injections have similar effects even over years of treatment.

Plagiocephaly is cranial synostosis caused by premature closure of one half of the coronal suture. It is manifested by asymmetry of the face of a varying degree with vertical strabismus on the affected side and tilting of the head to the sound side. The vertical deviation imitates ocular torticollis, there are, however, no signs of paresis nor a positive Bielschowski test. Treatment involves early opening of the coronal synostosis or later at least treatment of vertical strabismus. The authors operated successfully a 14-year-old girl with medium grade plagiocephaly. They describe the preoperative and postoperative state. The authors recommend, in case of asymmetry of the face and vertical strabismus, to consider the possible diagnosis of this anomaly.

Fifty-two patients affected by focal dystonia or hemifacial spasm were treated with repeated injections of botulinum toxin. A clinical improvement was observed in all patients with blepharospasm; clinical benefit had a mean duration of 10 weeks. Clinical results were less impressive, but also favorable in patients affected by spasmodic torticollis and by hemifacial spasm. In the latter, the incidence of drug-induced paresis was much higher than that observed in patients with blepharospasm, even though the doses of toxin injected were significantly lower.

Presented are the causes and clinical picture of the compensatory positioning of the head arising in the consequence of ocular changes and changes in the muscles of the neck. The material was divided into 3 groups: 1) with paresis of the ocular muscles (20 cases), 2) caused by nystagmus (20 cases) and 3) torticollis of muscular origin (20 cases). The basis of the differential diagnosis of compensatory positioning of the head of ocular origin and of torticollis of muscular origin as well as the criterion of a cooperation between the ophthalmologist and the orthopaedic surgeon are delineated.

85% of abducens palsies recover spontaneously; then their surgical treatment has not to be hastened. However many non regressive cases are frequently observed. Whatever they may be, partial or complete, uni or bilateral, always they give a great functional handicap which warrants a surgical care. The analysis of 74 successive cases allows to reveal some rules concerning the operative plan. In that respect the electro-oculographic recording often provides many essential informations. The recovery of a normal oculo-motor balance is usual in monolateral paresis. In bilateral complete palsies, in spite of muscle transposition procedures, we can only expect to reduce torticollis and to restore the ocular alignment in primary position, but abduction remains always impaired or fully impeded.
