[Oculomotor muscles involvement revealing dermatomyositis in a patient with rheumatoid arthritis].

INTRODUCTION: Oculomotor muscles (OMM) involvement in dermatomyositis (DM) and in rheumatoid arthritis (RA) is unusual. The DM always leads to OMM inflammation, whereas the RA particularly leads to tenosynovitis of the superior oblique muscle referred to as the Brown syndrome. OBSERVATION: The patient is a 43-year-old woman who gives a 17-year-history of severe seropositive RA with bilateral coxite. She was hospitalized for acute painful proptosis. The clinical examination revealed an orbital erythema and a muscular rhizomelic weakness. The muscular enzymes were increased. The orbital CT revealed in the right side, an enlargement of the superior rectus muscle that was enhanced after intravenous injection, which is compatible with myositis involvement. The muscular biopsy practiced at the level of the calf showed the specific histological signs of the DM. This orbital involvement was resolved with a high dose of corticosteroids. CONCLUSION: Our observation has the specificity of associating RA with DM with an involvement of the superior rectus muscle, which is due to the DM rather than the RA.

[Injection of botulinum toxin into the oculomotor muscles in disorders of ocular motility].

Injections of botulinum toxin into the oculomotor muscles was used in incorrectible diplopia, ocular torticollis, Duane's syndrome and congenital nystagmus. Favourable results were obtained and the sole complications which could be observed were a transitory ptosis and subconjunctival haemorrhages. Frequently 2 to 3 injections were sufficient for a permanent effect.

[Treatment of paralysis of cranial nerve VI: evaluation of the Hummelsheim method of transposition surgery of the oculomotor muscles].

The authors evaluated in a retrospective study the results of surgery in 28 patients with paralysis of the VIth cranial nerve. The standard surgical procedure which was selected as primary achieved orhtophoria in 21 patients. In 7 patients with persisting esotropia and diplopia transposition of the oculomotor nerves according to Hummelshein was indicated. After stabilization of the postoperative finding in all patients parallel position of the eyes and a improved compensatory position of the head was found. Markedly restored motility in abduction was observed only in patient. The method of first choice in treatment of paralysis of the sixth nerve but also of other oculomotor nerves are standard surgical procedures. By retro-position and resection of oculomotor muscles usually a satisfactory state in the primary position is achieved. Transposition operations are rather useful as supplementary operations in previously operated eyes. Indications are persisting diplopia and esotropia. Postoperative results as regards the primary position of the eyes are satisfactory but usually marked improvement of the motility cannot be foreseen.

[Morphology of oculomotor muscles and their nervous apparatus in lateral amyotrophic sclerosis in conditions during long-term artificial lung ventilation].

Light and electron microscopy, histochemical study of acetylcholinesterase (ACE) were used in examination of the state and innervation of ocular muscles in autopsy material from a patient who died of amyotrophic sclerosis (ATS). The patient had lived 14 years under artificial lung ventilation, ATS was diagnosed 22 years before the death. Light microscopy demonstrated the intactness of the muscle fibers and the presence of three types characteristic of the extraocular muscles: thin, granular and rough. Besides typical differences structural changes were observed in some muscle fibers of the myopathic character and inclusions not limited by membrane having filiform or granular structure. Ocular muscles had an intensive innervation. Nervous fiber terminals revealed by a reaction for ACE were represented by single motor plaques and multiple cluster-like endings. Ultrastructurally, nervous endings of two types differed by terminals and fold expression on the postsynaptic membrane. There were no pathological changes in axons and myelin. Thus, ocular muscles were not affected as well as their nervous apparatus at completion of AMS, this indicating the noninvolvement of this muscular allotype in a specific degenerative process.
