241. Study of Albuterol and Oxandrolone in Patients With Facioscapulohumeral Dystrophy (FSHD)

by standard DNA testing Weakness of the facial muscles, including frontalis, orbicularis oculi, or orbicularis oris Weakness of scapular stabilizers or foot dorsiflexors Ambulatory Weakness grade 2 or worse in the arm using upper extremity grading scale Exclusion criteria: Prior use of oral beta-2 agonists for a period of at least 1 year or within the past 3 months Concurrent use of other sympathomimetic agents, antidepressants, or beta-2 receptor blockers Pregnancy Known hypersensitivity to anabolic

242. Idiopathic facial paralysis: new therapeutic prospects with acetyl-L-carnitine. (Abstract)

of electromyograms (EMG) of the orbicularis oculi and oris muscles, by the Schirmes lacrimation test, by stapedial reflex test and a score scale for clinical assessment of paralysis. Results so far obtained have shown an earlier functional recovery of the nerve in those patients treated with acetyl-L-carnitine. Comparison between the affected and unaffected sides of the face revealed a statistical significance in the treated group (p < 0.05) as well as the amplitudes of the muscle action potentials (MAP) between

244. Habituation of facial muscle responses to repeated food stimuli. (Abstract)

Habituation of facial muscle responses to repeated food stimuli. We have shown in a series of studies that the human salivary response habituates to repeated presentation of gustatory cues. Parallel animal research has shown that mouthing and food acceptance also habituate. Facial expressions represent a complex response pattern in animals and humans that may provide an objective measurement of motivation to eat. The current study assessed whether facial muscles (orbicularis oris region

245. Organization of the central control of muscles of facial expression in man Full Text available with Trip Pro

Organization of the central control of muscles of facial expression in man Surface EMGs were recorded simultaneously from ipsilateral pairs of facial muscles while subjects made three different common facial expressions: the smile, a sad expression and an expression of horror, and three contrived facial expressions. Central peaks were found in the cross-correlograms of EMG activity recorded from the orbicularis oculi and zygomaticus major during smiling, the corrugator and depressor anguli oris (...) anguli oris during a contrived expression. However, no central peaks were found in the cross-correlograms of EMG activity recorded from the frontalis and orbicularis oculi or from the frontalis and zygomaticus major during the other two contrived expressions. It is concluded that a common synaptic drive is not present between all possible facial muscle pairs and suggests a functional role for the synergy. The origin of the common drive is discussed. It is concluded that activity in branches of common

246. Delayed verbal reactions are specifically impaired in patients with schizophrenia. (Abstract)

the perceived word in a first trial; in a second one, a delay (foreperiod) between the word presentation and a 'go' signal (eight asterisks) is interposed. Acousticograms and orbicularis oris EMG are recorded as responses. The ratio of the 1.5-s foreperiod delayed reaction time to the immediate reaction time reveals a facilitation of the executive system occurring during sustained purposeful attention, a characteristic function of the prefrontal cortex. A further ratio, with a 0.1-s foreperiod, has been

247. A modified temporalis transfer in facial reanimation. (Abstract)

A modified temporalis transfer in facial reanimation. A modified surgical procedure for temporalis transfer in facial reanimation of five consecutive cases is presented. Instead of the traditional stripping of the temporalis from its origin, its attachment at the coronoid removed, and to its end, the harvested fascia lata graft was sutured to lengthen the muscle's action. These fibres were then passed to the Orbicularis Oculi and Oris to aid in reanimation and to improve their tone

248. Trigemino-facial inhibitory reflexes in idiopathic hemifacial spasm. (Abstract)

Trigemino-facial inhibitory reflexes in idiopathic hemifacial spasm. We investigated trigemino-facial excitatory and inhibitory responses in perioral muscles in hemifacial spasm (HFS). We examined 15 patients affected with idiopathic HFS and 8 healthy controls. Five patients had spasms mostly limited to the periocular region and 10 had spasms also involving the perioral muscles. Responses were recorded from the resting orbicularis oculi (OOc), levator labii superioris (LLS) and orbicularis oris

249. The use of second-intention healing for partial-thickness Mohs defects involving the vermilion and/or mucosal surfaces of the lip. (Abstract)

cosmetic and functional results for the repair of partial-thickness defects involving the vermilion and/or mucosa of the lip. Defects involving more than 2 mm of the cutaneous lip or defects extending deeper than the superficial portion of the orbicularis oris muscle may result in cosmetic or functional deformity or both if allowed to heal secondarily.

250. ORAL MYOFUNCTIONAL AND ELECTROMYOGRAPHIC EVALUATION OF THE ORBICULARIS ORIS AND MENTALIS MUSCLES IN PATIENTS WITH CLASS II/1 MALOCCLUSION SUBMITTED TO FIRST PREMOLAR EXTRACTION Full Text available with Trip Pro

ORAL MYOFUNCTIONAL AND ELECTROMYOGRAPHIC EVALUATION OF THE ORBICULARIS ORIS AND MENTALIS MUSCLES IN PATIENTS WITH CLASS II/1 MALOCCLUSION SUBMITTED TO FIRST PREMOLAR EXTRACTION The aim of this study was to assess the presence of oral myofunctional alterations before and after first premolar extraction in Class II/1 malocclusion patients that could endanger the long-term dental arch stability.The study was performed by means of morphological, functional and electromyographic analyses in 17 Class (...) (orbicularis oris muscle) at rest and during swallowing, as well as the mentalis muscle behavior during the above-mentioned function, not showing statistically significant differences (p>0.05) after treatment (groups T1 and T2). However, group T differed significantly from group C (p<0.05). Lip posture during swallowing showed statistically significant differences (p<0.05) for subjects submitted to orthodontic therapy when compared to data acquired before the treatment. The electromyographic analysis

251. Electromyographic activity evaluation and comparison of the orbicularis oris (lower fascicle) and mentalis muscles in predominantly nose- or mouth-breathing subjects. (Abstract)

Electromyographic activity evaluation and comparison of the orbicularis oris (lower fascicle) and mentalis muscles in predominantly nose- or mouth-breathing subjects. The objective of this study was to evaluate and compare the electromyographic (EMG) activity of the orbicularis oris--lower fascicle (LOO) muscle and the mentalis muscle (MT)--in predominantly nose-breathing (PNB) and mouth-breathing (PMB) subjects.Thirty-four subjects, 22 PNB and 12 PMB, with Class II Division 1 malocclusions
