Several animal irritancy test methods whose criteria include sensory response, pain/discomfort or tissue damage were evaluated as to their ability to assess relative irritancy potential of the following surfactants: sodium lauryl polyether (12) sulfate (SLES), Miranol C2M (MC2M), Miranol MHT (MMHT), sodium coco methyl tauride (SCMT), triethanolamine lauryl sulfate (TEALS), ammonium lauryl sulfate (ALS) and sodium lauryl sulfate (SLS). Data from the mouse upper respiratory tract and mouse writhing tests indicated that SLES, MC2M and MMHT were the least irritating and SLS, ALS and TEALS were the most irritating. The blepharospasm test did not lend itself to this type of evaluation because sequential instillation of the surfactants produced eye anesthesia. Data from the Draize eye test indicated that SLES was the least irritating while MC2M was slightly more irritating. All other surfactants were equally irritating. The Draize skin test results showed that SLES again was the least irritating at all concentrations tested and that SLS and ALS along with TEALS and SCMT were the most irritating.

The results obtained in a retrospective study on clinical and pharmacological aspects of 41 patients suffering craniocervical dystonia (24 with blepharospasm, 17 with torticollis) and 11 with spasm are here presented. Mean age of symptoms onset was 57.4, 43.8 and 55.8 years old respectively; this variable was comparatively higher in females than in males with torticollis. The prevalence of blepharospasm and hemifacial spasm was higher in females. A 38.7% of patients suffering blepharospasm also presented oromandibular dystonia (Meige's syndrome). Other abnormal movements less frequently associated were cephalic tremor, postural hand tremor and larynx dystonia. In three cases with blepharospasm there was family history of Parkinson's disease and in two cases with torticollis there was family history of essential tremor. The mean age of onset was lower in patients with clonic torticollis and the evolution time of symptoms was longer than in those who presented the tonic type. Clonic torticollis were less frequently associated to pain. Trihexyphenidyl (anticholinergic) was the most efficient drug in craniocervical dystonia, and clonazepam in facial hemispasm. In general, as earliest the age of onset was, as better the therapeutical response was.

We studied 300 patients, 61% women, with mean age 49.7 years and mean duration of dystonia 7.8 years, to determine the demographic and clinical characteristics of cervical dystonia (CD) and its relationships to other movement disorders. Torticollis was present in 82%, laterocollis in 42%, retrocollis in 29%, and anterocollis in 25%; however, the majority (66%) had a combination of these abnormal postures. Scoliosis was present in 39%, local pain reported by 68%, and 32% had evidence of secondary cervical radiculopathy. In addition to CD, 16% of patients had oral dystonia, 12% mandibular dystonia, 10% hand/arm dystonia, and 10% had blepharospasm. Tremor was noted in 71% of patients; head-neck tremor was present in 60%, and tremor in other body regions was present in 32%. A family history of a movement disorder was present in 44% of the CD patients. Tardive dystonia was the cause in 6%; 11% had posttraumatic dystonia. Anticholinergic drugs provided moderate improvement in 33% of patients, but local intramuscular botulinum toxin injections relieved CD, local pain, or both in over 90% of all treated patients.

Botulinum A toxin was injected into the affected muscles in 20 patients with blepharospasm, 8 with torticollis and 12 with hemifacial spasm. In all cases blepharospasm and hemifacial spasm was abolished or markedly reduced. The only side effect was transient ptosis and diplopia. Patients with torticollis had a mild to moderate improvement of the dystonic posture and pain; dysphagia was the most troublesome side effect. Botulinum A toxin is an effective therapy in patients with focal dystonia and spasms.

The effects of fresh amnion on the course of morbid processes in corneal ulcers and burn disease of the anterior segment of the eye were investigated. The cornea was coated with amnion in 15 eyes with deep bacterial ulcers, in 10 eyes with herpetic ulcers of the cornea, and in 8 eyes with second and third-degree corneal and conjunctival burns. The amnion was obtained in cesarean section and fixed to the limbal conjunctiva with an uninterrupted suture all around. The next day after surgery the pain syndrome reduced, as did photophobia and blepharospasm in all the patients. In the group of patients with bacterial ulcers the cornea epithelialized on days 5-11, in those with herpetic ulcers on days 10-15, and in those with burns on days 8-12 after amnion coating. No cases with suppuration of the burnt surface when coated with the amnion were recorded. The amnion slid off the cornea on days 7-10 after it was layered on.

Medical treatment of dystonia usually results in an incomplete response and is frequently unsuccessful. Peripheral surgical therapy is available for some focal dystonias, but may only offer temporary relief and may have unacceptable complications. We have used local injections of botulinum toxin into the appropriate muscles for treatment of disabling focal or segmental dystonia in 93 patients with torticollis, blepharospasm, oromandibular dystonia (OMD), limb dystonia, lingual dystonia, and dystonia adductor dysphonia, in addition to four patients with hemifacial spasm. Significant relief of motor symptoms was seen in 69% of the patients with blepharospasm and 64% of patients with torticollis; 74% of the latter group with pain experience relief. Relief of symptoms was noted in most patients with OMD and limb dystonia, and all with lingual dystonia, dystonic adductor spastic dysphonia, and those with hemifacial spasm. Benefit averaged 2 1/2-3 months initially; however some patients experienced longer relief with subsequent injections. Adverse effects were transient, although 2 patients developed antibodies against the toxin, and we documented evidence for distant effects in others. This approach of chemically weakening contracting muscles in focal dystonia offers many advantages over pharmacotherapy and surgical therapy. Additional experience is needed to explore the proper doses, and potential for long term adverse effects.

In patients with functional ophthalmological disturbances classical acupuncture therapy was compared to a technique of inserting the needles close to superficial nerves. Seventy-five patients with migraine, 47 patients with functional blepharospasm, 18 with trigeminal neuralgia, and 9 with posttraumatic pain syndromes were treated. Treatment comprised seven sessions at four-day intervals. Of 62 patients undergoing classical acupuncture, 21 (33.9%) were subsequently free of complaints and 33 (53.2%) felt a great improvement. Nerve points were stimulated in 83 patients, 31 (38%) of whom were completely free of symptoms after treatment, and 45 of whom (54%) felt much better. Hence, there was no marked difference between the two methods as regards therapeutic effect. These results support the concept of acupuncture therapy being a combination of dermal stimulation and suggestion. The therapeutic approach to pain or blepharospasm by use of the mainly suggestive effects of acupuncture is recommended only if underlying organic diseases can be ruled out.

A 68-year-old man with intermittent blepharospasm complained of pain and induration after undergoing differential ablation of the seventh nerve. Because radiation therapy was ineffective, we inserted a 5-mm silicone tube into a serous cyst in the parotid gland. The induration subsided and the patient's recovery was uneventful.

We treated three patients who had intraepithelial neoplasia involving the visual axis and a subsequent decrease of visual acuity with topical mitomycin C 0.02% four times daily for ten to 22 days. In two of the three cases, the intraepithelial neoplasia was histologically confirmed. The intraepithelial neoplastic lesion was replaced by biomicroscopically normal epithelium within nine weeks of the beginning of drug administration and did not recur during the four to 12 months of follow-up. Adverse reactions to topical mitomycin in two patients ranged from minimal conjunctival hyperemia after 14 days to marked hyperemia, ocular pain, and blepharospasm after 22 days. These signs and the symptoms, however, disappeared after the drug was discontinued. Administration of topical mitomycin C 0.02% for two weeks may be an effective treatment for corneal intraepithelial neoplasia that affects the visual axis.

Botulinum toxin is now an established treatment for blepharospasm, hemifacial spasm, spasmodic torticollis, and spastic dysphonia. We report the effectiveness of botulinum toxin against painful limb myoclonus of spinal cord origin. The patient, a 16-year-old girl with a pulmonary vascular anomaly, Scimitar syndrome, suffered from an acute spinal cord infarct at age 11. She was left with paralysis of the right leg and bladder dysfunction. Four years after the original insult, she developed "painful cramping" and involuntary movements of the left thigh, which were unresponsive to a wide range of therapeutic trials. The movements were continuous, rhythmic, and confined to the left quadriceps muscles. Electromyographic examination revealed continuous myoclonic discharges. Treatment with botulinum toxin in the left quadriceps muscles resulted in complete cessation of pain and marked reduction in amplitude of the movements, both clinically and electromyographically. This observation indicates the efficacy of botulinum toxin in the treatment of painful spinal myoclonus.
