Review of Economic Value Drivers of the Treatment of Overactive Bladder

Overactive bladder (OAB) is a symptom-driven condition with economic burden estimated to be on the order of several hundred dollars or euros per patient in some North American and European countries. This work reviews recently published economic models to evaluate how health states are defined, what cost components are considered, and what utility values are used to estimate the cost effectiveness of OAB pharmacotherapies, botulinum toxin, or sacral neuromodulation. It was found that no clear standard exists for determining OAB health states, although most were defined by some measure of incontinence frequency. Costs of physician visits and incontinence pads were included in nearly all models; however, OAB-associated depression and nursing home costs were rarely included, despite being large cost drivers of global economic burden studies. Utility values used in the models ranged from 0.544 to 0.933, highlighting the uncertainty associated with how OAB patients value health-related quality of life. More research is warranted so that health states providing delineations among OAB symptom severity and quality of life are clinically and economically meaningful as well as meaningful to affected patients.

Cosmetic Practitioners Take Huge Risks Purchasing and Administering Illegal Botulinum Toxin Drug Products

In their article "Importing Injectables" in the September 2014 issue of the Journal of Drugs in Dermatology, Dr. Kenneth Beer and Karen Rothschild highlighted the possible harm to patients and practitioners from the use of unapproved botulinum toxin products - eg, Botox, Dysport, Xeomin, and Myobloc - and other cosmetic prescription drug products purchased from foreign or unlicensed suppliers.1 In the intervening years, the accuracy of their critique has been repeatedly demonstrated, as the dangers to patients' health, as well as to cosmetic practitioners' liberty, has only increased.

[Botulinum toxin therapy for spasticity]

Botulinum toxin (BTX) administered as an adjunct to other interventions for spasticity can act as a useful and effective therapeutic tool for treating patients disabled by spasticity. Presence of other non-reflex motor disorders (muscle stiffness, shortness, and contracture) can complicate the clinical course and disturb rehabilitative process of patients with spasticity. Treatment of spasticity using BTX can improve paralysis by correcting muscular imbalance that follows these diseases. In patients with chronic severe spasticity, we also have to address unique and difficult-to-treat clinical conditions such as abnormal posture and movement disorders. The effectiveness of BTX in treating some of these conditions is discussed. Because patients with neurological disabilities can show complex dysfunctions, specific functional limitations, goals, and expected outcomes of treatment should be evaluated and discussed with the patient, family members, and caregivers, prior to initiating BTX therapy. BTX therapy might improve not only care, passive function, but also motor functions in these patients by supplementing intensive rehabilitation with repetitive transcranial magnetic stimulation, transcranial direct-current stimulation, peripheral electrical stimulation, muscle stretching, and other rehabilitation strategies.

Cost considerations in the treatment of anal fissures

Anal fissure is a split in the lining of the distal anal canal. Lateral internal sphincterotomy remains the gold standard for treatment of anal fissure. Although technique is simple and effective, a drawback of this surgical procedure is its potential to cause minor but some times permanent alteration in rectal continence. Conservative approaches (such as topical application of ointment or botulinum toxin injections) have been proposed in order to treat this condition without any risk of permanent injury of the internal anal sphincter. These treatments are effective in a large number of patients. Furthermore, with the ready availability of medical therapies to induce healing of anal fissure, the risk of a first-line surgical approach is difficult to justify. The conservative treatments have a lower cost than surgery. Moreover, evaluation of the actual costs of each therapeutic option is important especially in times of economic crisis and downsizing of health spending.

Cost effectiveness of botulinum toxins for the treatment of depression: preliminary observations

The standard of care for the treatment of depression involves pharmacologic therapy with selective serotonin reuptake inhibitors (SSRIs). Cognitive therapy is typically utilized in addition to a pharmacologic intervention. However, the benefits of the drugs used may be marginal compared with placebo yet the costs associated with their use continue to increase. One potential treatment for depression utilizes botulinum toxins. At the present time there is a small body of evidence supporting their use for depression, the potential efficacy and cost effectiveness of this treatment warrants further consideration including head to head clinical trials.

Humanistic, utilization, and cost outcomes associated with the use of botulinum toxin for treatment of refractory migraine headaches in a managed care organization

BACKGROUND

Few patients with migraine syndrome receive treatment with preventive medication regimens, and some of these patients fail to gain adequate migraine relief. Botulinum toxin has been suggested to be effective in the treatment of migraine for a select population. An integrated health system created a medical policy and a supporting preauthorization form that permits coverage of botulinum toxin for the off-label treatment of migraine for patients who (1) fail at least 3 drug classes for acute treatment, (2) fail at least 4 different preventive medication classes, and (3) receive consultation from a neurologist.

OBJECTIVES

To (1) evaluate the impact of botulinum toxin therapy on quality-of-life (QOL) measures evaluated by direct member survey results, and (2) assess the use and cost of migraine-related medications and overall medical and pharmacy services pre- and post-botulinum toxin therapy.

METHODS

The study was a retrospective analysis of administrative claims data from a 500,000-member integrated health system for the time period January 1, 2003, to October 31, 2007. Administrative claims data were used to identify members with a billing code (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM]) for migraine (346.xx), tension headache (307.81), or headache (784.0) diagnosed by a neurologist. Administrative claims data for these patients were then queried for the use of botulinum toxin for dates of service from January 1, 2003, through October 31, 2006. A survey was sent to the identified patients (N=54) to assess 6 QOL measures associated with the use of botulinum toxin. Self-reported symptomatic improvement was assessed using a 5-point Likert scale for 6 questions regarding headache severity, headache frequency, use of rescue medications, productivity/absenteeism, recreational activities, and life enjoyment. For the subset of patients (n = 32) who maintained health plan eligibility from 18 months before through 18 months after the first botulinum toxin therapy claim (index date), medical and pharmacy claims data were used to assess the utilization and cost of specific medications and overall pharmacy and medical costs for the 18-month pre-index and post-index periods. Cost was defined as allowed charge, which is the sum of plan cost and member cost.

RESULTS

Of 54 surveys sent to all patients identified as having used botulinum toxin for the treatment of migraine from January 1, 2003, to October 31, 2006, 34 surveys were returned (63%). Almost 3 of 4 respondents (73%) reported moderate or better improvement in overall migraine or headache QOL measures, and 27% reported little or no improvement. For the 32 patients with continuous eligibility for the total observation period of 36 months, the average migraine-related pharmacy utilization, excluding botulinum toxin, increased by 50.5%, from 1.84 claims per patient per month (PPPM) in the 18-month pre-index period to 2.77 claims PPPM in the 18-month post-index period (P = 0.011) and by 59.5% by mean days supply (42.58 days to 67.93, P=0.008). Total migraine-related pharmacy cost increased by 80.9%, from $142.08 PPPM to $256.97 PPPM (P=0.013). Acute-treatment migraine-related pharmacy utilization increased from 1.23 claims PPPM to 1.92 claims PPPM (P=0.004). There was no significant change in either the number of claims for migraine prophylaxis medications (0.61 PPPM to 0.85 PPPM, P=0.121) or the use of hospital emergency room services related to migraine or headache (0.07 PPPM vs. 0.10 PPPM, P=0.449). The mean migraine-related and nonmigraine-related (i.e., all-cause) combined medical/hospital and pharmacy expense, including botulinum toxin, increased by 111.3%, from $651.13 PPPM in the pre-index period to $1,376.05 PPPM in the post-index period (P<0.001).

CONCLUSION

The majority of patients who received botulinum toxin for refractory migraine reported improvement in disease-specific symptoms and overall QOL, but total medical and pharmacy costs were higher in the period after treatment, and there was no reduction in the use of other migraine-related medications.

Botulinum toxin treatment of oesophageal achalasia in the old old and oldest old: a 1-year follow-up study

BACKGROUND

Intrasphincteric injection of botulinum toxin (BTX) has become one of the most frequent therapeutic approaches for the treatment of oesophageal achalasia. This treatment seems particularly effective in elderly patients who are not candidates for more invasive procedures.

AIMS

There are few or no data on BTX treatment of achalasia in the old old and oldest old. Therefore, we evaluated BTX treatment in a group of patients with achalasia in the extreme age range who were too ill or frail to undergo surgery or pneumatic dilatation.

PATIENTS AND METHODS

Twelve elderly achalasic patients (age range 81-94 years, average age 86 years) with American Society of Anesthesiologists (ASA) class III-IV status were recruited for the study. After baseline clinical and instrumental evaluations, BTX 100U was injected at time 0 and 1 month later. Clinical follow-up was carried out after 3, 6 and 12 months.

RESULTS

A significant improvement in symptom score was documented at each follow-up step. On the basis of improvements in scores, approximately 70% of patients were considered responders at the end of follow-up.

CONCLUSIONS

BTX treatment is an effective treatment in a substantial proportion of achalasic patients >80 years of age, in whom benefits are still detectable after 12 months. BTX is a therapeutic option in patients unsuitable for surgery or pneumatic dilatation.

Cost impact of botulinum toxin use in Medicaid-enrolled children with cerebral palsy

The use of botulinum toxin type A (BTX) in the management of spasticity in childhood cerebral palsy (CP) is increasing. This study examined annual health care service utilization and costs associated with BTX therapy for spastic CP in Medicaid-enrolled children receiving complete health care coverage (1997 to 1999). We used pair matching as well as recent statistical technique improvements (bootstrap method) to work with limited samples. The introduction of BTX was associated with an increase of approximately $62 per month in prescription costs for the patient. However, these costs were made up by reductions in hospitalization. When each year was examined individually, reimbursements for BTX users were not different from those for pair-matched non-BTX users. These data suggest that BTX therapy does not significantly add to the costs of treating Medicaid-enrolled children with CP.

[Botulinum toxin in tension-type headache]

Botulinum toxin has meanwhile been approved for a number of indications. It is also gaining acceptance in other indications with a major focus on pain. The most common type of headache is tension-type headache (TTH) the pathogenesis of which has not yet been unfolded. As it looks there are vascular, myofascial and supraspinal factors intertwined. It is felt that headache is triggered by myofascial stimuli. The application of botulinum toxin is an intelligent alternative since the favorable effect of pharmacologic and other therapies is limited. Application of BTX should be considered when the pericranial muscles are involved. One of the effects produced lies in the reduction of muscular stress, muscular ischemia and muscle tone. We still don't know whether additional mechanisms such as retrograde uptake and direct antiinflammatory potential are involved. Current data permit the conclusion that headaches are decreased in their frequency and distinctiveness. Significant untoward effects are not to be expected. Neither the ideal dose nor the optimum selection of injection sites have been established as yet, an individual injection scheme is apparently most promising. Injection of the trigger points seems to make sense.

[Spasticity and botulinum toxin in 2003. An update]

After the spastic foot in cerebral palsy, there are now wider indications for botulinum toxin injections in spasticity. Post stroke upper limb spasticity has been usefully treated by botulinum toxin in several studies, including double blind placebo-controlled studies. Two serotypes and one serotype B are marketed, with various properties. Botulinum toxin has been studied in multiple etiologies of spasticity. In multiple sclerosis, few studies revealed an efficacy in angulations and comfort. In spinal cord injuries, gait and sphincter disorders can be improved. In post stroke spasticity, lower limb angulations are improved, but gait remained difficult to evaluate. In upper limb spasticity, angulation, function and quality of life were improved in double blind, placebo controlled studies. Comparisons of costs and efficacy are made between botulinum toxin and the other antispastic methods.

East-west differences in the organization of botulinum toxin use in nine Central European countries

Availability and quality of expensive treatment modalities such as botulinum toxin (BTX) largely depend on organizational aspects such as costs, reimbursement by insurance companies, expertise and facilities for expert training, and the propagation of research. To investigate which determinants influence the organization of BTX' use throughout nine Central European countries (Austria, Croatia, Czech Republic, Germany, Hungary, Italy, Slovakia, Slovenia and Switzerland) we sent out questionnaires to leading BTX experts and consulted data banks of manufacturers and bulletins of international organizations. In Western European countries, there is a tendency for users to organize themselves in formal groups and to concentrate on research whereas the way how BTX is provided is diverse regarding qualifications of specialists and institutions. In the post-communist Eastern European countries, we found a tendency towards a centralized system of reimbursement and BTX treatment seems to be more in the hands of neurologists than any other specialists. Strong correlations were observed between the number of BTX centres, degree of organization of user groups and number of scientific publications, on the one hand, and parameters of healthcare performance and socioeconomic determinants, on the other. Our study suggests that in the nine countries surveyed, organizational aspects of BTX use vary considerably, whilst similarities are based mainly on socioeconomic rather than socio-demographic determinants.

Achalasia treatment in the elderly: is botulinum toxin injection the best option?

BACKGROUND

Achalasia treatment in elderly patients is a matter of controversy. Botulinum toxin injection has been proposed as the best option in this group of patients as it is a safe procedure. However, concern persists regarding its short-term effect.

AIMS

To analyse the clinical and economic effectiveness of botulinum toxin injection in the treatment of achalasia patients who are elderly.

METHODS

Seventeen consecutive achalasia patients older than 65 years were treated with 80 units of botulinum toxin. Clinical follow-up at 1, 6 and 12 months was performed. Control manometry when symptoms recurred was carried out. Results were compared with those of an historical control group of 16 achalasia patients also older than 65 years and who had been treated with endoscopic dilation. The costs of both procedures were compared.

RESULTS

Twenty-nine botulinum toxin injections were performed in the 17 patients of the botulinum toxin group (follow-up, 12-36 months). In the dilation group only two patients had to be retreated (follow-up, 12-108 months). No major complications were observed in either group. The average duration of symptom alleviation was 48 +/- 33 months for endoscopic dilation and 13.8 +/- 9.5 months for botulinum toxin injection. Maintaining a patient free of symptoms cost E348.31 per year for botulinum toxin injection, whilst if endoscopic dilation was chosen the cost was only E117.47 per year.

CONCLUSIONS

The effect of botulinum toxin injections wanes with time in elderly patients, necessitating repeated injections to keep the patients symptom-free. Due to the required repeated injections this procedure is more expensive than endoscopic dilation.

Botulinum toxin in the management of spasticity in adults

Botulinum toxin (BTX) is a powerful neurotoxin which blocks cholinergic transmission at the neuromuscular junction. Judiciously applied, it can reduce local muscle overactivity while maintaining the strength in other muscles. To date BTX has not been licensed for use in spasticity in the UK and the literature pertaining to clinical practice is still relatively scant. However, controlled trials have provided evidence of the effectiveness of BTX both in reducing spasticity itself and in achieving functional gain. The guidance given here to clinicians involved in the management of spasticity covers the types of patient suitable for treatment using BTX, the appropriate dosage, and the necessary follow-up procedures and documentation.

Treatment of achalasia: botulinum toxin injection vs. pneumatic balloon dilation. A prospective study with long-term follow-Up

BACKGROUND AND STUDY AIMS

In patients with achalasia, intrasphincteric injection of botulinum toxin (BTX) has been suggested as an alternative regimen to balloon dilation and has been shown to be superior to placebo injection. The aim of the present study was to test the effectiveness, the long-term outcome and the cumulative costs of BTX injection in consecutive patients with symptomatic achalasia in comparison with pneumatic balloon dilation.

PATIENTS AND METHODS

37 patients, who presented with symptomatic achalasia between January 1994 and December 1996 were treated with either BTX injection (n = 23) or pneumatic dilation (n = 14). Patients with short-term or long-term symptomatic failures of the initial procedure were treated again, either with the same or with the alternative method, depending on the initial response and on the patient's wish. Symptoms were assessed using a global symptom score (0 - 10) which was evaluated before treatment and 1 week, 1 month and then every 6 months after the treatment. In addition, body weight and recurrence of symptoms were noted and manometry was carried out before and after treatment. The patients were regularly contacted for the long-term follow-up.

RESULTS

There were significant improvements in the global symptom scores of all patients treated, in both the BTX injection group (before 8.2 +/- 1.3, after 3.0 +/- 1.6) and the dilation group (before 8.3 +/- 1.1, after 2.3 +/- 1.9). There was also a significant decrease of lower esophageal sphincter pressure after treatment in the BTX group and the dilation group. There were no significant differences with regard to overall treatment failure and long-term outcome between patients who had or had not received previous treatment. No major complications were encountered in either group. An actuarial analysis over 48 months comparing patients receiving BTX injection or balloon dilation demonstrated that after 12 months neither therapy was significantly superior. After 24 months a single pneumatic dilation was superior to a single BTX injection, and after 48 months all patients treated by BTX injection had experienced a symptomatic relapse. In contrast, 35 % of all patients treated by dilation and 45 % of patients treated successfully by dilation were still symptom-free in an intention-to-treat analysis after 48 months. When the overall costs of treatment and further treatment after recurrence were compared, dilation and BTX injection showed a similar cost-effectiveness (costs per symptom-free day) after 48 months.

CONCLUSIONS

BTX injection, which can be performed in an outpatient setting, is as safe and cost-effective as balloon dilation in symptomatic achalasia. Taking into account the lower long-term efficacy of BTX injection therapy, however, it is an alternative only in a minority of older or high-risk patients.

Botulinum toxin for people with dystonia treated by an outreach nurse practitioner: a comparative study between a home and a clinic treatment service

OBJECTIVE

To study whether a trained outreach nurse practitioner could provide a service that is as good as, or better than, that provided at a hospital outpatient clinic for people who had been diagnosed with dystonia and required treatment with botulinum toxin.

DESIGN

Randomized trial.

SETTING

An outpatient department of a regional neurorehabilitation center and patients' homes in northern England.

PATIENTS

Eighty-nine patients with a clinical diagnosis of spasmodic torticollis, blepharospasm, or hemifacial spasm who had ongoing treatment of dystonia with botulinum injections.

INTERVENTIONS

Individuals were randomly allocated either to receive ongoing botulinum injections at home by the nurse practitioner or to continue attending the hospital outpatient clinic and be injected by medical staff.

MAIN OUTCOME MEASURES

The following measures were recorded at each visit: demographic descriptors, dosage of botulinum toxin, treatment interval, side-effect profile, external referrals, and a questionnaire to determine qualitative opinion.

RESULTS

Efficacy and duration of the botulinum was similar in both groups. Botulinum dosage and side-effect profiles were similar in both groups except for significantly less dysphagia (p < .018) in the home group (7 vs 24 occasions). Subjective opinion by the patients indicated statistically significant preference for home injections. Economic analysis indicated that the overall cost of the treatment was less in the home injection group (total cost per visit $36.90 [ pound 23.36] vs $79.00 [ pound 50.01]), but this difference was not statistically significant.

CONCLUSION

A trained outreach nurse practitioner provided a service that was as good as, and in certain aspects better than, that provided by a hospital outpatient clinic. The nurse practitioner provided a more flexible, much appreciated, safe, and cost-effective service for this client group. Wider use of outreach nurse practitioners for dystonia should be encouraged.

The current use of botulinum toxin

Botulinum toxin is the most potent neurotoxin known, and has been in clinical use since the late 1970s. The toxin inhibits the release of acetylcholine from nerve terminals by inhibiting transport of the synaptic vesicles, thus causing functional denervation lasting up to 6 months. Our understanding of the mechanism of action of the toxin and the spectrum of diseases treatable with this agent continues to increase. Efficacy has been demonstrated in hemifacial spasm, dystonia, spasticity, hyperhidrosis and other conditions. Alternative serotypes are used in some centres, generally after the development of immunoresistance to the standard toxin (serotype A), and are likely to be in routine use in the near future. This paper reviews the history, pharmacology and current uses of botulinum toxin.

Pharmacotherapy with botulinum toxin: harnessing nature's most potent neurotoxin

Botulinum toxin (BTX), a potent biologic neurotoxin, commonly is associated with lethal outbreaks of food poisoning; however, it also plays a role as a therapeutic agent. Since the 1970s physicians have investigated BTX therapy in patients with neurologic disorders. The number of applications greatly expanded over the years to include certain focal dystonias (blepharospasm, torticollis, laryngeal dystonias, writer's cramp), strabismus, and a wide variety of other indications (gastrointestinal disorders, cosmetic wrinkle correction, spasticity, hyperhidrosis). BTX's safety and efficacy are reviewed.

A pharmacoeconomic evaluation of botulinum toxin in the treatment of spasmodic torticollis

We performed a prospective study in 21 patients to evaluate the cost of treatment of spasmodic torticollis (cervical dystonia) before and after botulinum toxin type A (BTA) treatment and to assess the impact of BTA treatment on quality of life. Data were recorded for the analysis over a period starting 8 months before and ending 7.2 +/- 0.2 months (mean +/- SEM) after the first injection of BTA. All patients received at least two BTA injections (2.9 +/- 0.2 injections per patient). We studied direct medical costs (drugs, outpatient and inpatient visits, diagnostic procedures, physiotherapy), clinical effects of BTA (clinical rating scale and patient's global assessment), quality of life (French version of the Nottingham Health Profile [NHP]), and adverse reactions. Costs associated with the treatment of spasmodic torticollis before the first BTA injection were 479 +/- 143 French Francs (FF)/patient/month (97 +/- 29 US $/pt/mo). During BTA treatment, costs were 1,126 +/- 147 FF/pt/mo (228 +/- 30 US $/pt/mo), including a mean cost of BTA of 771 +/- 131 FF/pt/mo (157 +/- 27 US $/pt/mo). Treatment with BTA significantly decreased clinical symptoms of spasmodic torticollis and improved the emotional, social, and pain-related domains of the quality of life assessment. Botulinum toxin type A treatment increases the cost of treating spasmodic torticollis but improves quality of life in terms of pain, social, and psychologic functioning in patients with spasmodic torticollis.

Intrasphincteric botulinum toxin versus pneumatic dilatation for achalasia: a cost minimization analysis

BACKGROUND

Pneumatic dilatation or intrasphincteric botulinum toxin injection provide effective symptom relief for patients with achalasia. Although intrasphincteric botulinum toxin injection is simple and safe, its efficacy may be short-lived. Pneumatic dilatation lasts longer, but esophageal perforation is a risk. We compared treatment costs for pneumatic dilatation and intrasphincteric botulinum toxin injection using a decision analysis model to determine whether the practical advantages of intrasphincteric botulinum toxin injection outweigh the economic impact of the need for frequent re-treatment.

METHODS

Probability estimates for intrasphincteric botulinum toxin injection were derived from published reports. Probability estimates for the pneumatic dilatation strategy were obtained by retrospective review of our 10-year experience using the Rigiflex dilator. Direct, "third-party payer" costs were determined in Canadian dollars.

RESULTS

Intrasphincteric botulinum toxin injection was significantly more costly at $5033 compared with $3608 for the pneumatic dilatation strategy, yielding an incremental cost of $1425 over the 10-year period considered. Sensitivity analysis showed that pneumatic dilatation is less expensive across all probable ranges of costs and probability estimates. The intrasphincteric botulinum toxin injection strategy is less costly if life-expectancy is less than 2 years.

CONCLUSIONS

Intrasphincteric botulinum toxin injection is more costly than pneumatic dilatation for the treatment of achalasia. The added expense of frequent re-treatment with intrasphincteric botulinum toxin injection outweighs the potential economic benefits of the safety of the procedure, unless life-expectancy is 2 years or less.

The long-term use of botulinum toxin for adult strabismus

PURPOSE

To characterize patients choosing repeated botulinum toxin injection as a treatment for their strabismus, and assess their demand for it over time (up to 8 years).

METHOD

Patients who had undergone at least eight injections were identified and their clinical records analyzed for diagnosis, demographic details, and demand for toxin injections with time. To establish any predictive variables, the details for these cases were compared with those of matched controls who had undergone fewer injections. Lastly, a questionnaire was mailed to research patients' views as to the indications and preferences for regular toxin injection as a method of treatment.

RESULTS

Ninety-five patients were identified (34 men, 61 women; median age 37 years), of whom 35 had consecutive exotropia and 16 had secondary exotropia. Other diagnoses represented were residual and primary deviations, restrictive exotropias, and oscillopsias. A trend of fewer injections over the attendance period was seen, and the only complication observed was upper lid ptosis in 1% of injections. Cases exhibited similar demographic composition to matched controls, but were more likely to have consecutive exotropia or secondary esotropia as a diagnosis. Univariate analysis showed evidence (p < 0.001) of an association between the number of previous operations and the odds of being a case. No evidence was found that cases and controls lived at differing distances from our hospital. The questionnaire found that 71% of patients stated appearance as the prime reason for seeking treatment, and 37% stated simplicity of toxin therapy as their reason for reattendance. Twenty-six percent of the patients were disillusioned with the results of previous surgery and preferred toxin therapy as a means of controlling their symptoms.

CONCLUSION

Botulinum toxin injection is an appropriate long-term treatment for some strabismus patients who choose not to undergo further surgery. A trend toward fewer injections with time was observed, and no adverse effects were associated with long-term treatment.

[Botulin in the treatment of local dystonia]

Botulin A has been introduced for the treatment of local dystonia especially blepharospasm and torticollis. Three cases of blepharospasm and 5 cases of torticollis were treated with botulin injections directly into the muscles by a method presented in detail. Good effects were obtained in blepharospasm but very poor in torticollis, which may have been due to too low doses of the toxin and inadequate choice of injection points. The method is safe and in only 1 case transient weakness of the masseters was noted.
