How to treat xerosis?
In general, there is a twofold approach to the treatment of xerosis: (1) minimizing irritation and (2) moisturization. 2 Patients should be instructed to limit bathing, especially in soapy baths that strip oil from skin and leave it chapped. 2 While some experts recommend bathing once daily in warm water and mild soap, others suggest bathing only every other day and supplementing with sponge baths of the axillae and anogenital areas, since these areas are rarely affected by xerosis. 1,2 Patting the skin dry instead of rubbing can also help. Detergents, rubbing alcohol, and skin care products that contain alcohol and other drying agents should be avoided if possible. Irritating materials (e.g., wool) should not be placed next to the skin. 1

What is xerosis diagnosis?
The differential diagnosis of xerosis includes atopic eczema, autosomal dominant ichthyosis, nummular eczema, and stasis dermatitis, as outlined in table 2. Inherited ichthyoses, characterized by excessive accumulation of scales on the surface of the skin, are classified according to clinical features such as age at onset (e.g., birth, infancy, or childhood), type of scale (e.g., fine, large and dark, large and coarse, thick and warty), associated clinical findings (e.g., corneal opacities, ectropion, blisters) and genetic features (e.g., autosomal dominant, X-linked, autosomal recessive). In these cases, it is recommended that genetic counseling and treatment guidance be sought through consultation with a dermatologist. 3
What causes xerosis of the stratum corneum?
While the exact cause of xerosis is unknown, the condition is related to altered lipid composition of the stratum corneum, in addition to other changes in epidermal differentiation. 1 It appears as though xerosis does not occur as a result of decreased water in the skin, but rather is the result of abnormal keritinization and desquamation. 2.
What is the condition of the skin that is dry and rough?
Staten Island, New York. US Pharm. 2006;4:28-32. Dryness of the skin, known as xerosis, or xeroderma, is a common condition in the elderly. As people age, the outer layer of skin loses water, causing the surface to become dry and rough. 1 Incidence of xerosis increases with age, and prevalence of the condition in the United States may increase, ...

The name C. urealyticumwas first proposed in 1986 to describe the formation of bladder stones in vivo in an animal model by urealytic bacteria of the CDC coryneform group D2 (old name of C. urealyticum).3
What are the characteristics of C. urealyticum?
urealyticumwas originally characterized based on its biochemical properties, including failure to produce acid from carbohydrates and the ability to hydrolyze urea.12,13The cell wall peptidoglycan of C. urealyticumcontains meso-diaminopimelic acid. Arabinose and galactose are the major cell wall sugars. Tuberculostearic acid and short-chain mycolic acids are present resembling mycobacterium tuberculosis.2The degree of relatedness of C. urealyticumto other Corynebacteriumspecies can be determined by using DNA–DNA hybridization studies2,14and 16S ribosomal ribonucleic acid (rRNA) sequence analysis. A 16S rDNA sequence-based phylogenetic tree of the species belonging to the genus is shown in Figure 1.15,16Studies were done using a small-subunit rRNA sequence data and observed a close phylogenetic relationship between C. urealyticumand C. jeikeium.2However, the difference between them is that C. jeikeiumis non-urealytic and produces acid from glucose among others.17,18
