[Occurrence of cosmetic allergy].

In a retrospective study among 310 patients with ordinary contact dermatitis, 115 were found to have allergic contact dermatitis caused by cosmetic products. The most commonly involved sites were hands (including fingers) and face. The most frequently identified sensitizers were fragrances, including lichen and compositae extracts, preservatives and balsam of Peru. About 28% of the cutaneous reactions occurred among patients 20-29 years of age.

Clinical and immunohistochemical study of the effect of a cosmetic product in patients with asteatotic eczema.

Cutaneous xerosis is a common clinical condition associated with an altered barrier function of the stratum corneum. Xerotic skin appears dry, rough and slightly scaling. Patients complain of pruritus and stinging. Our aim was to investigate the clinical effects of a cosmetic ointment (Scherilan) in patients with circumscribed senile xerosis (also called asteatotic eczema). Moreover, variations in expression of epidermal proteins such as keratin (K)-5 and involucrin, detected by immunohistochemistry, were also evaluated before and after topical treatment. We enrolled 30 patients (11 males, 19 females) with asteatotic eczema. We examined dryness, roughness and desquamation and symptoms such as itching and dryness. A score of 0 to 3 was assigned to each of these parameters. A biopsy was performed in seven patients before and after a 21-day topical treatment. All skin specimens were then immunostained with antibodies to K5 and involucrin. At day 7 or 21 of treatment all signs of xerosis and pruritus were significantly reduced; furthermore, the reduction increased with the duration of therapy. Before treatment K5 was strongly expressed in stratum basale (SB) and stratum spinosum (SS), while involucrin was strongly expressed in stratum granulosum (SG) and the upper portion of SS. In contrast, after treatment immunostaining for K5 was restricted to SB and the lower part of SS, while involucrin showed intense staining in SG. We highlight the importance of treating cutaneous xerosis with an ointment such as this one, which probably induces an increase of lipid content of the SC intercellular matrix.

Tattooing, body piercing, and permanent cosmetics: a historical and current view of state regulations, with continuing concerns.

The popularity of tattooing, body piercing, and permanent cosmetics demands up-to-date state legislation. The objective of this article is to present a historical perspective and nationwide review of current state regulations for body art. Methods comprised Internet and telephone inquiries to state agencies. It was found that while 36 states have changed their body art legislation since 1998, the overall strength of the regulations varies widely. The author concludes that it is unrealistic, given the amount of body art performed in the United States, to prohibit body art, emphasize only business licensing, or have limited state regulations while local municipalities establish separate policies. Concerns remain about standard precautions, adequate documentation of complications, and lack of uniform regulations. Quality protection will mean taking a more comprehensive approach to effective regulations and enforcement.

[Studies for analyzing prohibited ingredients such as estriol in cosmetics].

Estriol (EO) is nominated as the prohibited ingredients in cosmetics in Japanese Pharmaceutical Affairs Act. So the analytical method using HPLC for EO was investigated. After placing 1.0 ml of EO solution at 50 microg/ml and 0.5 g of the lotion into a 10-ml volumetric flask, the methanol was added to make until that volume and this solution was used as the testing solution. Milky lotion was procedured as follows: After placing 1.0 ml of EO solution at 50 microg/ml and 0.5 g of the milky lotion into a 10-ml volumetric flask, the methanol was added to make until that volume. The suspending mixture was moved to a centrifuging tube with a cap. After centrifuging at 3000 rpm for 5 minutes, the supernatant was used as the testing solution. The testing solution of 20 microl was determined by HPLC using the ODS column (CAPCELL PAK C18 column, 4.6 x 250 mm), the mixture of water and acetonitrile (31:9) and the detection wavelength of 285 nm. The working curve from 1.0 to 6.0 microg/ml showed a linear line between the concentrations of EO and the peak area. There was no interference of peak of EO from the lotion and milky lotion.

[Studies for analyzing prohibited ingredients such as tetracaine hydrochloride in cosmetics].

Tetracaine hydrochloride (TH) is nominated as the prohibited ingredients in cosmetics in Japanese Pharmaceutical Affairs Act. So the analytical method for TH was investigated by HPLC. After adding 5 ml of TH solution at 10 microg/ml and 2 ml of salicylic acid solution at 75 microg/ml as the internal standard to 0.5 g of the lotion, the mixture was made up to 10 ml with a mixture of water and methanol (1:1) as the testing solution. Milky lotion was procedured as follows: After adding 5 ml of TH solution at 10 microg/ml and 2 ml of internal standard solution to 0.5 g of the milky lotion, the mixture was made up to 10 ml with a mixture of water and methanol (1:1). Two milliliter of this mixture was placed into a centrifuging tube with a cap and 2 ml of hexane was added. After shaking vigorously and centrifuging, the lower layer was used as the testing solution. In the case of the cream, the other procedures were used: 0.5 g of cream was placed into a 10-ml volumetric flask and 1 ml of tetrahydrofuran was added. After dissolving, the mixture of methanol and water (1:1) was added to make up 10.0 ml. Two milliliter of this mixture was placed into a centrifuging tube with a cap and 2.0 ml of hexane was added. After shaking vigorously and centrifuging, the lower layer was used as the testing solution. The testing solution of 20 microl was analyzed by HPLC using the ODS column (CAPCELL PAK C18 column, 4.6 x 250 mm), the mixture of acetonitrile and 50 mmol/l phosphate buffer(pH 2.0)(7:3) and the detection wavelength of 303 nm. The working curves from 0.5 to 6.0 microg/ml showed a linear line between the concentrations of TH and the peak area ratio. There was no interference of peak of TH from the lotion, milky lotion and cream.

Topical anesthetics for cosmetic and laser dermatology.

Many effective and simple topical anesthetic products are available today and commonly used in medical and non-medical settings. The increased use of topical anesthetics, especially by non-physicians in the medical and non-medical settings, has resulted in increased rates of complications including ineffective anesthesia, allergy, and even potential fatalities. This review focuses on various techniques and formulations for topical anesthesia and their appropriate applications in cosmetic and laser dermatology. In addition, the history, pharmacology, and clinical complications of topical anesthetics are discussed.

Positive patch-test reactions to gold: patients' perception of relevance and the role of titanium dioxide in cosmetics.

BACKGROUND: Positive patch-test reactions to gold that are without obvious clinical relevance are common. We speculate that titanium dioxide in cosmetics and sunscreens may adsorb gold particles in jewelry that occasionally contacts facial skin and cause contact dermatitis on this area despite the absence of dermatitis under gold jewelry worn on the hands. OBJECTIVE: To identify subgroups of gold allergic patients who improve with avoidance of gold. METHODS: A questionnaire was mailed to 102 gold-allergic patients. RESULTS: There were 49 responses, of which all but one were from women. When asked to evaluate the statement that patch testing with gold was useful to them, one-third of respondents agreed completely, one-third agreed in part, and one-third disagreed. The majority of patients reported that their dermatitis improved after patch testing, but most were avoiding other allergens in addition to gold. CONCLUSIONS: Avoidance of gold earrings did not appear to benefit patients with earlobe dermatitis, but total avoidance of gold jewelry on the hands and wrists did seem to benefit a subgroup of patients with facial and eyelid dermatitis who wore powder, eye shadow, or foundation on affected areas.

Simultaneous determination of chlorinated bacteriostats in cosmetic and pharmaceutical products.

A high-performance liquid chromatography method has been developed for simultaneous determination of triclosan (2,4,4'-trichloro-2'-hydroxydiphenyl ether) and triclocarban (3,4,4'-trichlorocarbanilide) in cosmetic and pharmaceutical products. The two compounds could be separated on a Nucleosil C(18) column and eluted with acetonitrile and water (70:30, v/v) as the mobile phase and detected with a differential refractive index detector. The retention times of triclosan and triclocarban were 5.81 and 2.99 min, respectively. The results obtained were in good agreement with those obtained by a differential pulse voltammetric method.

Cotton honeydew (Gossypium hirsutum L.) extract offers very interesting properties for hair cosmetics and care products.

Cotton honeydew extract is composed of a unique combination of oligosaccharides, including fructose, glucose, inositol, melezitose, saccharose, trehalose and trehalulose. Studies have shown that these oligosaccharides exhibit a protective effect. Therefore, we were interested in studying the effect of these oligosaccharides on normal and damaged human hair. Both clinical and scanning electron microscopy (SEM) studies were performed. Standardized human hair samples were used to determine the effect of a rinse-off mask with 1% cotton honeydew extract on the ultrastructure of hair. In addition, hair samples were submitted to different aggressions, following various experimental protocols. SEM showed that, without extra aggression, the cuticle scales appeared to lie more smoothly in the hair in cotton honeydew extract-treated samples than in untreated samples. The extract-treated hair samples were also less prone to chipping. In contrast, the control, untreated hair samples retained a dry and damaged appearance and were prone to chipping and progressive splitting. In a clinical study, 15 volunteers had half of their hair treated with a formula with 1% honeydew extract and the other half was left untreated as a control. Pictures and visual evaluation of the hair showed that the honeydew extract formula left the hair with a smoothness that was far superior to the control side and this result was confirmed by SEM. In addition, mRNA studies on epidermal cells were performed and confirmed the stimulating effect of honeydew extract on keratin synthesis. These results demonstrate that cotton honeydew extract can be of great use in hair care products and cosmetics.

[Free versus non-free treatments with laser and intense pulsed light in dermatology: distinguishing medical laser treatments to be provided free of charge from cosmetic self-payment treatments].

Lasers and light sources are increasingly used in dermatology. Due to the limited financial resources of the public health care system, the Danish Dermatological Society has developed recommendations for distinguishing medical laser treatments to be provided free of charge from cosmetic self-payment treatments. Several considerations underlie the recommendations: present legislation; the diagnosis, etiology, severity, and anatomical location of the disease; and the availability of evidence-based treatments. It is suggested that the recommendations constitute the basis for referring patients to dermatological treatment involving laser and intense pulsed light in Denmark.

[Studies for analyzing the prohibited ingredients such as acetohexamide in cosmetics].

Acetohexamide (AH) is nominated as the prohibited ingredients in cosmetics in Japanese Pharmaceutical Affairs Act. So the analytical method for AH was investigated by HPLC. The lotion or milky lotion of 0.5g was put into a 10-ml volumetric flask. After adding 1.0ml of AH solution at 50 microg/ml into the volumetric flask, the mixture was made up to 10ml with methanol as the testing solution. Creams were procedured as follows; 0.5 g of cream was put into a 10-ml volumetric flask. After adding 1.0ml of tetrahydrofuran into the volumetric flask, the mixture was stirred for several minutes and the ingredients of the creams were dissolved. After adding 1.0ml of AH solution at 50 microg/ml into the volumetric flask, the mixture was made up to 10ml with methanol. One milliliter of the mixture including AH at 5 microg/ml was exactly put into a test tube with a cap and then 1 ml of water and 1 ml of hexane were added. After shaking vigorously, stand for several minutes. After centrifuging, the hexane layer was eliminated and the residual mixture was used as the test solution. The testing solution of 20 microl was analyzed by HPLC using the ODS column (CAPCELL PAK C18 column, 4.6 x 250mm), the mixture of acetonitrile and 50 mmol/l phosphate buffer(pH 5.3)(3:1) and the detection wavelength of 247 nm. The working curve from 0.5 to 6.0 microg/ml showed a linear line between the concentrations of AH and the peak areas. There was no interference of peak of AH with the ingredients such as methylparaben, ethylparaben in the lotions, milky lotion and creams.

Availability and chemical composition of traditional eye cosmetics ("kohls") used in the United Arab Emirates of Dubai, Sharjah, Ajman, Umm Al-Quwain, Ras Al-Khaimah, and Fujairah.

This study was undertaken in order to determine the availability and chemical composition of potentially lead-toxic traditional eye cosmetics ("kohls") in six of the seven emirates of the United Arab Emirates (UAE). Thus of especial interest was the percentage of the purchased samples that contained the toxic element lead. A total of 53 observably different kohl samples were found to be available overall in the six emirates: Dubai, Sharjah, Ajman, Umm Al-Quwain, Ras Al-Khaimah, and Fujairah. It was found that 19 of these samples had been previously analyzed by us in studies covering Oman, Abu Dhabi (city), and Egypt (Cairo). The techniques of X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) were used to analyze the remaining 34 samples. Overall, for the 53 kohl samples, it was found that 20 (38%) contained a lead compound (galena, PbS) as the main component. The other main components were found to be one of the following: amorphous carbon, calcite/aragonite (CaCO3), goethite (FeO(OH)), hematite (Fe2O3), sassolite (H3BO3), talc (Mg3Si4O10(OH)2), or zincite (ZnO).

[Evaluation of the cosmetic effect of orbital endoimplantation after removal the eyeball].

The purpose of our study was to evaluate the cosmetic effect of endoimplantation after removal the eyeball. The removal of the globe creates anatomic and physiological alteration of the orbital tissue and orbital bones. A volume deficit occurs when an eye is enucleated. Deep upper lid sulcus, ptosis, lower lid laxity, and enophthalmus of the artificial eye together constitute the postenucleation socket syndrome, which creates an asymmetry of the face. The orbital prosthesis by placing it in the orbital cavity allows correcting volume deficit, so the implant with attached extraocular muscles, together with an artificial eye, creates an illusion of real eye. Forty patients were operated on in Clinic of Eye Diseases of Kaunas University of Medicine Hospital. Twenty patients underwent removal of the eye and procedure of orbital implant insertion (main group). Twenty patients had just an eyeball removal without insertion of an orbital implant (control group). There was a statistically significant difference in exophthalmometry data between main and control groups (14.20+/-2.73 vs. 10.35+/-1.23 mm, respectively; p<0.05). The motility of artificial eye laterally (4.30+/-1.66 mm), medially (3.65+/-1.23 mm), up (3.70+/-1.13 mm), and down (3.40+/-1.19 mm) in the main group was significantly better as compared to the control group (p<0.05), where motility of the artificial eye was 0.60+/-0.68 mm laterally, 0.70+/-0.92 mm medially, 0.30+/-0.66 mm up, and 0.30+/-0.47 mm down. Therefore, a much better symmetry, better movement of the artificial eye, and less severe form of postenucleation syndrome were observed in patients who underwent orbital endoimplantation after eyeball removal.

Hair cosmetics.

Alterations in the cuticle, cortex, and medulla are necessary to modify the hair cosmetically. The hair can be modified externally by the use of shampoos to remove excess sebum, conditioners to restore shine, and styling aids to increase manageability. Several different formulations of all these products exist, depending on the needs of the patient. Furthermore, the hair can be modified both externally and internally through the use of hair dyes, permanent waving lotions, and hair straighteners. Use of these products causes external damage to the hair shaft by disrupting the overlapping cuticular scales, rendering the hair susceptible to static electricity and the effects of humidity while decreasing manageability and shine. Internal damage created by these products decreases the hair shaft's elastic properties, allowing increased hair breakage. The dermatologist can better aid the patient with hair difficulties if he or she has an understanding of the formulation and effects of products designed to cleanse, beautify, and modify the hair.

Cosmetics in blacks.

Blacks comprise a phenotypically heterogeneous group with respect to skin and hair. They are uniquely multihued with at least 35 different possible shades of pigmentation, and there is considerable variability in hair texture. This accounts for many of the unique skin and hair cosmetic requirements and customs in the black race. These grooming practices may present perplexing problems for the dermatologist when viewed in the context of resultant skin disease; therefore, an awareness and understanding of skin and hair products used by blacks, grooming techniques, and their consequences are essential for clinicians caring for black patients.

[Good must drive out evil. On cosmetic treatment agents and earlier times' viewpoint on skin diseases].

The interest in skin preparation and "cosmetics" has increased in recent years. This development, which seeks to satisfy the patients' wishes and requirements for a kind but at the same time effective treatment is of historical significance. The treatment of skin diseases was in earlier times pervaded by another attitude, to the effect that evil should drive out evil, e.g. syphilis, scabies and psoriasis. The physician prescribes but it is the patient who executes the treatment, a point more often borne in mind with regard to the diseases of today.
