Pseudo-skin

In a new well (or in a recompleted or reperforated well), if perforations are incomplete, then a positive skin value will be present. However, it is present as i pseudo-skin, not as skin due to acid-removable formation damage. The total skin effect may be written as equation (3.3), which refers to the large number of pseudo-skin factors that may exist, including phase- and rate-dependent effects partial completion and slant and incomplete perforations." In equation (3.3), s is the only skin that acidizing can address. 

Mastocytomas and diffuse cutaneous mastocytosis are further manifestations of cutaneous mastocytosis (CM) [9]. Solitary mastocytomas are common in children. Most are present at birth or develop in infancy. These lesions are flat or mildly elevated, well demarcated, solitary yellowish red-brown plaques or nodules, typically 2-5 cm in diameter. Diffuse cutaneous mastocytosis is a rare disorder characterized by diffuse mast cell infiltration of large areas of the skin that presents in infants in the first year of life. Severe edema and leathery indurations of the skin leads to accentuation of skin folds (pseudo-lichenified skin) and a peau-dbrange-like appearance. Systemic complications include hypotension and gastrointestinal hemorrhage. Infants and young children with considerable mast cell infiltration of the skin sometimes exhibit blister formation in the first 3 years of life. MPCM and other forms of CM have been classified in a consensus nomenclature (table 1) [10].

The 4-10 cyclic analog 14 (Table I) Is quite Inactive In both systems, but relative to the linear pseudo-lsosterlc analog 15 much more so In the lizard skin system (29). Addition of Lys-11 to the cyclic 4-10 analog to give analog 13 leads to a large Increase In potency In the lizard but not the frog skin system (30). 

Long-term use frequently induces hyperplasia of the gums. Skin rashes are seen in up to 10% of the patients. Serious, most probably pseudo allergic skin eruptions can also occur. 

Hypersensitivity, probably as a manifestation of pseudo-allergy is not infrequent. Especially in patients with impaired renal function various skin eruptions can be followed by a potentially fatal syndrome with fever, hepatic and renal dysfunction and eosinophilia. 

Hereditary haemochromatosis Usuahy with family history of cirrhosis, skin hyperpigmentation, diabetes melhtus, pseudo-gout and/or cardiomyopathy, all due to iron overload. 

When injected into the skin, local anesthetics often cause pseudo-allergic reactions, with similar symptoms to immediate type allergy (42). However, true immediate hypersensitivity to local anesthetics is extremely rare. 

Two patients, aged 75 and 65 years, were given raltitrexed for colorectal cancers. After 5 and 7 days they developed erythematous, edematous, and purpuric skin reactions associated with weakness, diarrhea, and moderate fever (5). The lesions were painful and pseudo-cellulitic. They were generalized in the first case and localized to the legs in the second. They subsided 15 days after drug withdrawal.

The development of cosmetic microemulsion cleansers with alkyl polyglycosides (APG) was described by Forster et al. [4]. This class of non-ionic surfactants has excellent environmental and skin compatibility. Cosmetic cleanser multicomponent systems are required to have good foaming and cleansing performance. Figure 8.3 shows a pseudo-ternary phase diagram of a five-component formulation. It consists of water, the oil dioctyl cyclohexane (DOCH), the non-ionic surfactant C12/14-APG, the anionic surfactant fatty alcohol ether sulphate (FAES) and the co-surfactant sorbitan monolaurate (SML). The phase diagram...
