Natural Itchy Scalp Treatment Systems
There is little commonality in the scientific methods, processes, and formulations required for the wide variety of cosmetics and toiletries in the market. Products range from preparations for hair, oral, and skin care to lipsticks, nail polishes and extenders, deodorants, body powders and aerosols, to quasi-pharmaceutical over-the-counter products such as antiperspirants, dandruff shampoos, antimicrobial soaps, and acne and sun screen products.
Although viral titres fall in the circulation at this time there is significant and persistent virus replication within lymph nodes and spleen. The clini-414 cally latent period may last 8-10 years and circulating CD4 T-cell count remains normal for most of this period. However, there is a delayed, gradual but progressive fall in CD4 T lymphocytes in most patients, who may remain asymptomatic for a prolonged period despite modest lym-phopenia. A number of minor skin problems such as seborrhoeic dermatitis are characteristic of the end of the latent phase.
A product can be both a cosmetic and a drug. Examples of cosmetic-drugs include deodorants with antiperspirant claims, toothpastes with anticaries claims, antidandruff shampoos, and makeup preparations with sunscreen protection. Cosmetic-drugs must comply with both cosmetic and drug labeling requirements. Section 502(e) of the Food, Drug and Cosmetic Act requires that drug products list all active ingredients on the label. If a product is both a drug and a cosmetic, the inactive ingredients must be listed in accordance with Section 701.3 of the FDA regulations, with some exceptions 33 . Briefly, this means that the sunscreen active ingredients must be listed separately using their drug designations and the other ingredients must be listed in decreasing order by their percent w w using their International Nomenclature Cosmetic Ingredient (INCI) designations 36 .
Ciclopirox olamine (Loprox) is a pyridone derivative available for the treatment of cutaneous dermatophyte infections, cutaneous C. albicans infections, and tinea versicolor caused by Malassezia furfur. It interferes with fungal growth by inhibiting macromolecule synthesis.
Into each others confers unexpected plasticity to the DC system. DC are uniquely adept at decoding the fungus-associated information and translating it in qualitatively different adaptive T-cell immune responses (Romani & Puccetti, 2006a). PRR (such as CR, FcR, C-type lectins (such as DC-SIGN and dectin-1), MR, and TLR determine the functional plasticity of DC in response to fungi and contribute to the discriminative recognition of the different fungal morphotypes. DC (both human and murine) are now known to recognize and internalize a number of fungi, including A. fumigatus, C. albicans, C. neoformans, H. capsulatum, Malassezia furfur, and Saccharomyces cerevisiae and fungi and fungal products may affect DC functioning as well (Romani & Puccetti, 2006a Buentke & Scheynius, 2003). DC are also known to cross-present exogenous fungal antigens through uptake of apoptotic macrophage-associated fungal antigens (Lin et al., 2005). Profiling gene expression on DC by microarray technologies...
Tinea capitis primarily affects school-aged children, appearing as one or more round patches of alopecia. Hair shafts broken off at the scalp may appear as black dots. Sometimes tinea capitis appears as non-specific dandruff, or gray patches of hair, or areas of scales, pustules and erythema. A localized, boggy, indurated granuloma called a kerion may develop.
Azelaic acid (Azelex) is a naturally occurring dicar-boxylic acid produced by the yeast Malassezia furfur. Azelaic acid inhibits tyrosinase, a rate-limiting enzyme in the synthesis of the pigment melanin. This may explain why diminution of melanin pigmentation occurs in the skin of some patients with pityriasis versicolor, a disease caused by M. furfur. Azelaic acid is bacteriostatic against a number of species thought to participate in the pathogenesis of acne, including Propionibacterium acnes. The drug may also reduce microcomedo formation by promoting normalization of epidermal keratino-cytes. Azelaic acid is used for the treatment of mild to moderate acne, particularly in cases characterized by marked inflammation-associated hyperpigmentation.
Based on new active substances are first categorized as prescription only until sufficient information and experience have been gained regarding their safety. Whether or not the cost of their prescription is covered by the state depends on not only medical but also political considerations of their perceived personal and social benefits. Some examples may clarify this. The antifungal imidazoles clotrimazole and ketoconazole were strictly limited prescription only medicines when they were marketed in the early 1970s for topical fungal infections. They are now available OTC for the self-treatment of thrush and dandruff, ketoconazole being regularly promoted on the radio. Peptic ulceration was generally treated surgically when simple antacids failed to relieve symptoms. Increasingly sophisticated forms of highly selective vagotomy were practised by gastric surgeons to try and separate the acid-suppressing effects of such an operation from its considerable undesirable adverse effects....
