Skin crusts were reported on mice exposed repeatedly to 5 mg phenol as a 5% (w/v) solution for 32 weeks, whereas skin ulceration was observed in mice exposed to 5 mg phenol as a 20% (w/v) solution (Salaman and Glendenning 1957). The skin ulceration healed in 4 weeks after the end of the exposure. 

There are four commonly occurring states of stress, shown in Fig. 3.2. The simplest is that of simple tension or compression (as in a tension member loaded by pin joints at its ends or in a pillar supporting a structure in compression). The stress is, of course, the force divided by the section area of the member or pillar. The second common state of stress is that of biaxial tension. If a spherical shell (like a balloon) contains an internal pressure, then the skin of the shell is loaded in two directions, not one, as shown in Fig. 3.2. This state of stress is called biaxial tension (unequal biaxial tension is obviously the state in which the two tensile stresses are unequal). The third common state of stress is that of hydrostatic pressure. This occurs deep in the earth s crust, or deep in the ocean, when a solid is subjected to equal compression on all sides. There is a convention that stresses are positive when they pull, as we have drawn them in earlier figures. Pressure,...

O Impetigo is a skin infection that most commonly afflicts young children. It is caused by group A streptococci or Staphylococcus aureus and is characterized by the development of numerous blisters that rupture and form crusts. Dicloxacillin, cephalexin, and topical mupirocin are considered the antibiotics of choice for treatment of impetigo.

Within the first 2 to 3 days of exposure a person will experience symptoms such as malaise, fever, headache, chills, and backache. The fever can last 1 to 5 days. Usually after the fever is gone, a skin eruption or rash appears. It begins as a pimple lesion for 1 to 4 days, becomes blister-like for 1 to 4 days, and then fills with pus for 2 to 6 days. It then forms a crust that falls off 2 to 4 weeks after the first skin lesion appears, leaving pink scars. An important characteristic is that all smallpox lesions in any affected area are generally found in the same state. In contrast, chickenpox lesions are not synchronous they form in crops. Smallpox lesions are also said to be more numerous on the face and extremities rather than the trunk, unlike chickenpox. The case fatality rate in unvaccinated patients is 15 to 40%. In vaccinated people, the fatality rate is <1%. Patients with smallpox are infectious as soon as a rash is evident and remain infectious until their scabs fall off— a duration of about 3 weeks.3... 

Overland Runoff The fraction of rainfall or irrigation water that flows over a land surface from higher to lower elevations, known as overland runoff, is an additional pathway for contaminant transport. Runoff occurs when the amount of rain or irrigation water is greater than the soil infiltration capacity. The formation of a crust on the soil surface is a major contributor to runoff formation in arid and semiarid zones, because it decreases the infiltration capacity. The soil crust is a thin layer (0-3 mm) with a high density, fine porosity, and low hydraulic conductivity compared to the underlying soil. This skin forms as a result of falling raindrops or sodification of soil clays. 

Nickel itch is a dermatitis resulting from sensitization to nickel the first symptom is usually pruritis, which occurs up to 7 days before skin eruption appears. The primary skin eruption is erythematous, or follicular it may be followed by superficial discrete ulcers that discharge and become crusted or by eczema. The eruptions may spread to areas related to the activity of the primary site such as the elbow flexure, eyelids, or sides of the neck and face. In the chronic stages, pigmented or depigmented plaques may be formed. Nickel sensitivity, once acquired, is apparently not lost of 100 patients with positive patch tests to nickel, all reacted to the metal when retested 10 years later. ... 

Sensitive skin may become excessively red, edematous, blistered, or crusted. If these effects occur, discontinue medication until skin integrity is restored or adjust to a tolerable level. True contact allergy is rare. 

Local skin reactions include edema, erosion/ulceration, erythema, flaking/scaling/dryness, scabbing/crusting, vesicles, and weeping/exudate.

Wool fat or suint.—The potash found in plants is obtained from the soil and the potash in the soil is one product of the decomposition of rocks which form the earth s crust. The potash which herbivorous animals—e.g. sheep—draw from the land is largely exuded as an oily sweat from the skin, and called, after the French, suint. In the first century of our era, Dioscorides called the mixture of wool fat and water oTowos, eesypus, a name which it retained up to the middle of the seventeenth century. CEsypus is mentioned several times by Ovid. In spite of its disagreeable smell it appears to have been used by the Boman ladies as one of their choice cosmetics. It is mentioned in N. Culpeper s Pharmacopoeia Londi-nensis (London, 1653), but it soon afterwards disappeared from the pharmacopoeia...
