Abstract
BACKGROUND Relaxation of hyperactive facial muscles by injection of botulinum toxin type A (BOTOX, Allergan Inc., Irvine, CA) represents the most common cosmetic procedure performed in the United States. OBJECTIVE The objective of this split-face randomized double-blind study was to determine the effect of epinephrine (EPI) on the efficacy of BOTOX treatment of muscle hyperactivity in the upper face. MATERIALS AND METHODS Fourteen subjects (ages 39-57 years) with moderate to severe periorbital rhytides were enrolled. Study patients were blinded to the two treatment arms, BOTOX and BOTOX plus EPI 1:100,000. Subjective and objective evaluations were performed at 0 and 4 days and 1, 3, and 6 months, and clinical improvement was assessed using a nominal scale from 0 to 4, corresponding to 0, 1% to 25%, 26% to 50%, 51% to 75%, and 76% to 100% improvement, respectively. The incidence of adverse events was also recorded. RESULTS Fourteen subjects with moderate to severe periorbital rhytides were treated with BOTOX or BOTOX plus EPI. One subject was discontinued from the study after receiving asymmetric doses of BOTOX. At 4, 30, and 90 days after treatment, subjective and objective improvement scores revealed that EPI enhanced the efficacy of BOTOX when compared to BOTOX alone. By 3 months, the effect of BOTOX and BOTOX plus EPI had peaked and continued to fall through 6 months. One of 14 patients did not appear to respond to BOTOX treatment. Both treatments were well tolerated with no serious adverse events. CONCLUSION To our knowledge, we are the first to test under randomized double-blind conditions the effect of EPI on efficacy of BOTOX. Our data suggest that addition of EPI may accelerate the rate of onset as well as the short-term efficacy of BOTOX for treatment of periorbital rhytides.

Abstract
This study corroborates that the resting tone is indeed increasing with age. And that like in the Face Recurve concept, the deep fat is expelled superficially because of mimic muscle shortening. Botulinum toxin is therefore described for a new indication: resting tone decrease in order to slow down muscle shortening and consequently structural aging. Injections can be performed very early in the ageing process, when it is only visible in contraction, before the appearance at rest of wrinkle. Precision of the injection is related to the recent determination of motor end plate location in every mimic muscle. Finally, a new possibility for botulinum toxin injection is the blockage of muscular regeneration in order to stabilize the section of the age marker fascicles performed in the Face Recurve concept. This new indication is also useful in reconstructive surgery for treatment of the marginal mandibular lip deformity in patients with chronic unilateral facial palsies.

Abstract
Botulinum toxin A treatment continues to increase in popularity and number. Many more patients are undergoing cosmetic Botox procedures and many, diverse practitioners are providing them. The best results are obtained from a careful history and physical examination of the patient combined with a detailed understanding of facial and neck anatomy. Understanding the dynamic anatomic relationships, such as agonist-antagonist muscles and contraction force vectors, is key to providing the patient with an excellent outcome.

Abstract
Botulinum toxin is a unique pharmaceutical agent in wide-scale use for cosmetic and multiple therapeutic applications. Physicians using these agents for esthetic purpose must realize the potential for future therapeutic needs. Because most indications require repeated injections, the recipient is at risk for immunologic reactions with possible formation of neutralizing antibodies. An individual who is injected with botulinum toxin for cosmetic purposes could someday require an effective form of type A toxin for dystonia, pain, or spasticity.

Abstract
The injection of botulinum toxin (Botox, Allergan, Irvine, CA) is the most common cosmetic procedure in the U.S. In the past 5 years, its use has climbed over 388%. In 2005, business development managers from Allergan audited 1695 patient charts from the top 54 cosmetic practices in Canada. Despite the increasing popularity of this nonsurgical treatment, on average only 57% of patients return for a second injection within 6 months. In the author's clinical practice 92% of patients return for a second injection in this time frame. This paper will examine various factors that appear to result in satisfied patients with a high retention rate. This article will show that panfacial botulinum toxin injected in multiple sites with appropriate dosing improves patient retention.

Abstract
A high-fat meal induces transient hyperlipidemia characterized by elevated triglyceride-rich lipoproteins (TRL) which are composed mainly of chylomicrons. The purpose of this work was to investigate the effect of this transient hyperlipidemia on the pharmacodynamics of lipophilic drugs, using DDT as a model compound since it binds extensively to TRL and has a distinct neurotoxic effect. The postprandial hyperlipidemia in rats was induced by oral administration of peanut oil and was monitored by measurement of plasma triglyceride levels. The control group received water instead of oil. The rats received a continuous intravenous infusion of DDT (10 mg/h) until onset of a predefined pharmacodynamic endpoint (facial muscle tremor). Plasma and brain samples were then obtained and assayed for DDT. Rats with postprandial hyperlipidemia required higher dose of DDT to induce onset of facial muscle tremor. At the pharmacodynamic endpoint, oil treated rats had significantly higher concentrations of DDT in plasma and in the chylomicron fraction, but DDT brain concentrations were the same in both groups. In conclusion, a high-fat meal induces postprandial hyperlipidemia that may significantly alter the pharmacological profile of lipophilic compounds that bind to TRL. This is due to alteration of the distribution characteristics of the lipophilic compound through its association with postprandial lipoproteins. However, this pharmacokinetic phenomenon did not affect the concentration-effect relationship at the site of action in the brain.

Abstract
PURPOSE To evaluate the incidence of temporary dry eye and the effects on lacrimal gland tear production after treatment of lateral canthal rhytids with botulinum toxin type A injections. METHODS Twenty-six crow's feet areas were injected with botulinum toxin type A in 13 women with an age range of 31 to 58 years. A total of 10 units of botulinum toxin was injected per side, with two separate injections. Schirmer 1 testing was performed before and at 1 week, 1 month, and 4 months after the injections in all patients. The test was repeated at 6 months and 9 months for the patients whose Schirmer test results were not back to baseline at the 4-month follow-up. Statistical significance was evaluated with paired t test analysis. RESULTS Overall, no statistical difference was found in Schirmer test results from baseline at 1 week (p = 0.23), 1 month (p = 0.32), or 4 months (p = 0.30) after injection. Five eyes of three patients had a significant decrease in Schirmer test results from baseline at 1 week and 1 month after injection. Three eyes of 2 patients had a significant decrease in Schirmer test results at 4 months after injection. Only one patient reported dry-eye symptoms at the 4-month follow-up. Schirmer test results of two eyes of one patient remained significantly lower than baseline at 6 months follow-up, which returned to the normal range at 9 months. CONCLUSIONS Botulinum toxin for lateral canthal rhytids usually does not suppress tear production. However, decreased tear production after botulinum toxin injection for crow's feet is a possible complication and patients should be advised of the small but definite risk of a temporary dry eye.

Abstract
STUDY OBJECTIVES The objective was to evaluate the responsiveness of upper airway muscles to hypercapnia with and without intrapharyngeal negative pressure during non-rapid eye movement (NREM) sleep and wakefulness. DESIGN We assessed the genioglossal muscle response to CO2 off and on continuous positive airway pressure (CPAP) (to attenuate negative pressure) during stable NREM sleep and wakefulness in the supine position. SETTING Laboratory of the Sleep Medicine Division, Brigham and Women's Hospital. PATIENTS OR PARTICIPANTS Eleven normal healthy subjects. INTERVENTIONS During wakefulness and NREM sleep, we measured genioglossal electromyography (EMG) on and off CPAP at the normal eupneic level and at levels 5 and 10 mm Hg above the awake eupneic level. MEASUREMENTS AND RESULTS We observed that CO2 could increase upper-airway muscle activity during NREM sleep and wakefulness in the supine position with and without intrapharyngeal negative pressure. The application of nasal CPAP significantly decreased genioglossal EMG at all 3 levels of PETCO2 during NREM sleep (13.0 +/- 4.9% vs. 4.6 +/- 1.6% of maximal EMG, 14.6 +/- 5.6% vs. 7.1 +/- 2.3% of maximal EMG, and 17.3 +/- 6.3% vs. 10.2 +/- 3.1% of maximal EMG, respectively). However, the absence of negative pressure in the upper airway did not significantly affect the slope of the pharyngeal airway dilator muscle response to hypercapnia during NREM sleep (0.72 +/- 0.30% vs. 0.79 +/- 0.27% of maximal EMG per mm Hg PCO2, respectively, off and on CPAP). CONCLUSIONS We conclude that both chemoreceptive and negative pressure reflex inputs to this upper airway dilator muscle are still active during stable NREM sleep.

Abstract
Botulinum toxin for facial enhancement is currently the most popular aesthetic procedure performed in the United States. New developments have occurred within the last few years. Patients prefer having multiple areas of the upper face treated which increases patient satisfaction. Treatment of the forehead is now being accomplished with fewer units of botulinum toxin. This helps preserve the natural look of some movement of the forehead. Men require more units of botulinum toxin than women. Combination therapy using botulinum toxin along with lasers or filler substances is ideal. Aesthetic medicine knowledge has progressed, contributing a greater understanding of botulinum treatment for advanced areas of the face. The orbicularis oris, mentalis, and depressor anguli oris are now routinely treated and help improve overall facial appearance. Other forms of botulinum toxins (additional type A or type B toxins) are available, each with advantages and disadvantages.

Abstract
Patients with Rasmussen encephalitis (RE) may develop a variety of involuntary movements. We report a 26-year-old woman who presented with a 3-year history of progressive, continuous myoclonus of the left side of the face and left arm as well as left spastic hemiparesis. Magnetic resonance imaging of the brain showed right hemisphere and basal ganglia atrophy, and 24-hour electroencephalogram demonstrated diffuse slowing with random sharp waves in both hemispheres. An 18-fluoro-deoxy-glucose positron emission tomography scan indicated hypometabolism of the right cerebral hemisphere, including basal ganglia and thalamus. We successfully treated her myoclonus with injections of botulinum toxin A into the left zygomaticus muscle.

Abstract
The present study investigated the role of peripheral group I metabotropic glutamate receptors (mGluRs) in MO-induced nociceptive behaviour and inflammation in the masseter muscles of lightly anesthetized rats. Experiments were carried out on male Sprague-Dawley rats weighing 300-400 g. After initial anesthesia with sodium pentobarbital (40 mg/kg, i.p.), one femoral vein was cannulated and connected to an infusion pump for intravenous infusion of sodium pentobarbital. The rate of infusion was adjusted to provide a constant level of anesthesia. Mustard oil (MO, 30 microl) was injected into the mid-region of the left masseter muscle via a 30-gauge needle over 10s. After 30 microl injection of 5, 10, 15, or 20% MO into the masseter muscle, the total number of hindpaw shaking behaviour and extravasated Evans' blue dye concentration in the masseter muscle were significantly higher in the MO-treated group in a dose-dependent manner compared with the vehicle (mineral oil)-treated group. Intramuscular pretreatment with 3 or 5% lidocaine reduced MO-induced hindpaw shaking behaviour and increases in extravasated Evans' blue dye concentration. Intramuscular pretreatment with 5 mM MCPG, non-selective group I/II mGluR antagonist, or MPEP, a selective group I mGluR5 antagonist, produced a significant attenuation of MO-induced hindpaw shaking behaviour and increases in extravasated Evans' blue dye concentration in the masseter muscle while LY367385, a selective group I mGluR1 antagonist, did not affect MO-induced nociceptive behaviour and inflammation in the masseter muscle. These results indicate that peripheral mGluR5 plays important role in mediating MO-induced nociceptive behaviour and inflammation in the craniofacial muscle.

Abstract
Schwartz-Jampel syndrome (SJS) is a rare congenital disorder of continuous myotonia, causing visual and eyelid problems such as blepharospasm, acquired ptosis, and blepharophimosis. We report the management of blepharospasm in two sisters with Schwartz-Jampel syndrome with application of botulinum toxin type A (BTX-A), as an alternative to the surgical treatments, such as orbicularis oculi myectomy, levator aponeurosis resection, and lateral canthopexy as described in the literature. Three consequent doses of commercially available BTX-A (Botox-Allergan, Inc. 100 u/via) were injected to orbicularis oculi muscle in two sisters with Schwartz-Jampel syndrome. At the least, the authors waited for a six-month interval to prevent development of sensitivity to BTX-A in patients. No significant improvement was observed after the injection of first dose of BTX-A, with the total dose of 25 units of BTX-A to each orbicularis oculi muscle of the eyes. The muscle tone weakened after the second dose, which was the twice as such of the first applied total dose (50 units of BTX-A to each orbicularis oculi muscle of the eyes) and significant functional and cosmetic improvements were achieved after injection of the third dose, in which the total applied dose was the same as the one applied in second dose. The blepharospasm and eyelid alterations caused by Schwartz-Jampel syndrome should be treated to provide functional and cosmetic improvements. Application of BTX-A to orbicularis oculi muscle for the treatment of blepharospasm could be considered as an alternative to levator resection, and lateral canthopexy in Schwartz-Jampel syndrome.

Abstract
BACKGROUND Botulinum toxin (Botox) is the mainstay treatment for benign essential blepharospasm. Current treatment practice appears restricted by several reports demonstrating adverse effects and resistance to high-frequency, higher-dose therapy. This study aimed to explore whether high-dose, high-frequency treatments could be used without developing secondary resistance and without significant side-effects in patients refractory to conventional Botox doses. METHODS From a cohort of 120 patients being treated with Botox therapy for benign essential blepharospasm and idiopathic hemifacial spasm, case notes from six patients were retrospectively examined. In these patients, therapy had exceeded the recommended 50 units per side for a duration greater than 12 months and at less than 3 monthly intervals. Patterns in subjective severity grading and percentage of improvement as well as reported side-effects were analysed. RESULTS All patients described greater than 60% improvement and 0-2 severity grading over a 3- to 15-year period with no evidence of secondary resistance. Side-effects were minor, transient and less frequently reported at higher doses. CONCLUSION In a select group of patients, Botox therapy can be used effectively at doses higher than recommended over long periods with minimal side-effects and little evidence of secondary resistance.

Abstract
The use of injectable agents, specifically soft tissue fillers and botulinum toxin type A, has risen dramatically over recent years, due to the increased demand for minimally invasive techniques. In fact, today they represent the most commonly performed cosmetic procedures in the United States, with botulinum type A injections topping the list. In the treatment of the aging face, these agents, when used individually or in combination, can effectively decrease rhytids and restore lost volume. The result is a fuller, smoother, more youthful appearance. This article provides an overview of botulinum type A (Botox Cosmetic; Allergan, Inc., Irvine, CA) and the two injectable fillers most commonly used in our practice, namely hyaluronic acid (Restalyne; Medicis Aesthetics, Inc., Scottsdale, AZ) and human-derived collagen (Cosmoderm and Cosmoplast; Inamed Aesthetics, Inc., Santa Barbara, CA). Although we commonly use autologous fat as an injectable filler for facial-volume augmentation, its discussion is beyond the scope of this article. Conceptually, the aging face can be divided into upper, middle, and lower thirds. Using this framework, we will discuss our treatment strategies for addressing each facial region. General principles, preinjection evaluation, and specific approaches and techniques for each anatomic region will be discussed, with particular emphasis on the benefit of using dermal fillers in conjunction with botulinum toxin type A to achieve optimal aesthetic results for facial rejuvenation.

Abstract
BACKGROUND Major depression is a common and serious disease that may be resistant to routine pharmacologic and psychotherapeutic treatment approaches. OBJECTIVE To evaluate the efficacy of botulinum toxin A treatment of glabellar frown lines in treating patients with major depression, using a small open pilot trial. METHODS Patients who met DSM-IV criteria for ongoing major depression in spite of pharmacologic or psychotherapeutic treatment were evaluated with the Beck Depression Inventory II (BDI-II) before receiving botulinum toxin A to their glabellar frown lines. Two months later, all patients were re-evaluated clinically and with the BDI-II. RESULTS Ten depressed patients were treated with botulinum toxin A, and 9 of 10 patients were no longer depressed 2 months after treatment. The tenth patient had an improvement in mood. CONCLUSION To our knowledge, these are the first reported cases of depression treated with botulinum toxin A.

Abstract
BACKGROUND Wounds of the face, especially those lying perpendicular to the lines of Langer, are known to heal poorly with conspicuous scarring. Different methods have been tried to tackle this problem, including corticosteroid injections, irradiation, ultrasound, silicone applications, and many others. However, as expected, their effects were far from satisfactory, because they do nothing to alleviate the underlying pathologic process, which is the distracting effect of muscle pull on immature collagen. METHODS In 40 patients with ugly scars of the face, botulinum toxin was used to induce temporary paralysis of the muscles during revision surgery, thus minimizing tension on healing wound edges until the collagen could mature. RESULTS Using both objective and subjective assessment scales, 90 percent of patients ended up with an improved outcome. This new technique has been proven effective in primates and in this study was shown to be as effective in humans, yielding results superior to those of any other treatment modality. CONCLUSION In view of the results of this study, it is considered worthwhile to offer patients with ugly scars of the face botulinum toxin injections simultaneous with revision surgery.

Abstract
Oromandibular dystonia is a focal dystonia involving the masticatory and/or tongue muscles. This report describes 2 female patients with jaw-closing dystonia treated by surgical resection of the coronoid process. The patients could not open their mouths due to involuntary jaw-closing muscle contraction. We first treated them by injecting lidocaine and alcohol (muscle afferent block) into the masseter and temporal muscles and then botulinum toxin. However, the trismus improved mildly and transitorily. Therefore, coronoidotomy was done under general anesthesia. The jaw opening increased to 50 mm. Coronoidotomy is useful for patients with jaw-closing dystonia in whom other therapies are ineffective.
