Presenting signs and symptoms include weakness, abdomi- nal pain, leg pain, fever, cough, and neurologic symptoms. Polyarteritis nodosa is a necrotizing vasculitis of small and medium-sized muscular arteries. There may be kidney involvement, arthritis, arthralgia, or immunofuorescence examination shows IgA deposits in ves- myalgia, as well as hypertension. Up to 40% of patients sel walls, which is in accord with a diagnosis of Henoch- may have skin involvement manifested as a maculopapular Schoenlein purpura.

Immunologically, immune subcutaneous tissue, especially prominent late in the disease. Certain drugs, food, and immunizations have also been suspected as etiologic agents. The disease usually occurs in children 4 to 7 years of age, although it can occur in adults. Histopathologically, there is a diffuse leukocytoclastic vasculitis involving small ves- sels. Children may manifest lesions associ- ated with the skin, gastrointestinal tract, or joints, whereas in adults the disease is usually associated with skin fndings. The skin lesions begin as a pruritic urticarial lesion that develops into a pink maculopapular spot that matures into a raised and darkened lesion. The maculopapular lesion may ultimately resolve in 2 weeks without leaving a scar. Patients may also have arthralgias associated with the large joints of the lower extremities. The severe muscle weakness may interfere with breathing if respiratory muscles are affected. Contemporary research hopes to identify epitopes on the autoantigen(s) that interact Figure 17. Patients may develop poly- to fetus, newborns of mothers with this disease may also clonal hypergammaglobulinemia.

Patients with this disease have an that are critical to chemical transmission of the nerve impulse at the neuromuscular junction. AchR antibodies are heterogeneous with some showing specifcity for antigenic determinants other than those that serve as acetylcholine or alphabungaratoxin binding sites. As many as 85 to 95% of myasthenia gravis patients may manifest acetylcholine receptor antibodies. Thyroxine is a hormone that is synthesized and released by (a) the thyroid gland that regulates cell metabolism, body tem- perature, use of energy and normal functioning of the central nervous system and cardiovascular system.

Before ening the “peaking” or wrinkle above the tail of the treatment, asymmetries in the brow and muscle activ- brow that commonly occurs when frontalis is spared.

The pattern of injections in the male If the needle tip remains in the dermis, excessive resis- patient differs, with more aggressive chemodenerva- tance is felt and the solution may leak onto the surface tion over lateral frontalis to maintain an aesthetically of the skin. M icrodroplets of botulinum toxin injected intrader- mally in the cheeks may improve cheek lines, but the risk of mouth asymmetry still exists [22]. Although rare, lateral injections should be made at least 1 cm from the bony orbital margin to prevent spread into the globe, resulting in extraocular muscle weakness and diplopia [23]. The fnger is placed on the rim as injec- tions are made superfcially, either in the dermis or subcutaneous plane between the visible blood vessels (Fig. As a general rule, 3–4 injections can be made, keeping the inferior injection lateral to an imag- inary line dropped vertically from the lateral canthus (Fig. Infraorbital injections can be made in the pretarsal portion of orbicularis oculi, however, to reduce lid bulging (Fig. Before treating the lower eyelid, example, 114 U Dysport is used for treatment of the frown and the snap test should be performed.

In these patients, skin on either side of the nose where there is maximal the injection can be made at the insertion point of the wrinkling.

To treat “smokers’ lines,” four injections into orbicularis oris are made 5 mm above the vermilion border. Using Dysport, 2 U are placed just under the dermis, two on either side with two further injections in the lower lip if required (Fig. The patient should be warned that even with conservative doses a transient subjective feeling of weakness lasting about 1 week can occur. Additional injections can be made after at least 2 weeks if no improvement is observed and the patient reports no weakness. The most inferior injection should not be over the zygoma, where denervation of maximally (Fig. The injections should be placed the lip elevators can occur at the same depth bilaterally to avoid asymmetry.

Prendergast lower face where they insert into the dermis and pull the tissues inferiorly. In the author’s view, other techniques such as suture face lifting are more effective and more appro- priate to improve jawline defnition. A square-jaw appearance may be caused by masse- teric hypertrophy, particularly in Asian patients. Botulinum toxin injections into the masseter at the angle of the jaw induces a partial paralysis leading to disuse atrophy. Three injections into the bulk of the muscle at the angle of the mandible is suffcient (Fig. An additional injection into lower but more may be required depending on the size and procerus softens the transverse nasal lines near the glabella strength of the muscle. Treatments are repeated at 3–4 month intervals until atrophy has occurred and facial shape has improved. Once muscle reduction has been achieved, subsequent treatments are less frequent [25]. Complications due to the spread of the toxin into perioral muscles are unusual [26].
