The superficial nerve, however, mainly affects the skin in the calf and on top of the foot. Loiasis can be diagnosed by finding microfilariae in blood collected during daytime; however, since microfilaremia may be absent, filarial serologic tests may be helpful. Drug-resistant organisms are frequently acquired in the tropics. Symptoms of nerve injury include paresthesias, loss of sensation and position sense, impaired motor function, cranial nerve malfunction, changes in reflexes, and impairments in glandular secretion. Unlike cellulitis, erysipelas lesions are raised, there is a clear line of demarcation at the edge of the lesion, and the lesions are more likely to be associated with fever. Besides examining for symmetrical skin tone, inspect the mucous membranes, lips, nail beds, and sclera for color changes that may not be visible otherwise.

Duran-McKinster C, Rivera-Franco A, Tamayo L, De La Luz Orozco-Covarrubias M, Ruiz-Maldonado R. An accumulation of factors placing the aging person at risk for skin disease and breakdown include the thinning of the skin, the decrease in vascularity and nutrients, the loss of protective cushioning of the subcutaneous layer, a lifetime of environmental trauma to skin, the social changes of aging, the increasingly sedentary lifestyle, and the chance of immobility.

The most common risk factor is age. The common peroneal nerve winds around the proximal neck of the fibula to reach the anterior leg where it divides into the superficial and deep peroneal nerves. It is caused by infestation with the larval stage of the African tumbu fly Cordylobia anthropophaga or the Latin American bot fly Dermatobia hominis.

Also supplies via branches the muscles in the lateral and anterior compartments of the leg. Yes:Newborn infants' eccrine glands do not secrete sweat in response to heat until the first few months of life; newborn temperature regulation is ineffective. This occurs mainly in chronic suppurative inflammatory disorders of the skin in which causative organisms spread via lymphatics. However, both of these studies are biased in that they do not include skin problems that were diagnosed and, in many cases, easily managed during travel or that were self-limited. Linear lesions act as diagnostic clues in many disorders. Rarely, the worm can be visualized crossing the conjunctiva of the eye or eyelid.

Both topical and systemic treatments may be effective; the species of the infection often determines the treatment modality. It occurs in infectious disorders like due to implantation of infectious agent in the skin during trauma leading to development of isomorphic linear lesions like in Koebner's phenomenon.

Melanotic macules following Blaschko's lines in McCune-Albright syndrome.
