Safety review of phenoxyethanol when used as a preservative in cosmetics.

Phenoxyethanol, or 2-phenoxyethanol, has a large spectrum of antimicrobial activity and has been widely used as a preservative in cosmetic products for decades. It is effective against various Gram-negative and Gram-positive bacteria, as well as against yeasts, and has only a weak inhibitory effect on resident skin flora. According to the European Scientific Committee on Consumer Safety, phenoxyethanol is safe for all consumers - including children of all ages - when used as a preservative in cosmetic products at a maximum concentration of 1%. Adverse systemic effects have been observed in toxicological studies on animals but only when the levels of exposure were many magnitudes higher (around 200-fold higher) than those to which consumers are exposed when using phenoxyethanol-containing cosmetic products. Despite its widespread use in cosmetic products, phenoxyethanol is a rare sensitizer. It can be considered as one of the most well-tolerated preservatives used in cosmetic products.

European task force on atopic dermatitis position paper: treatment of parental atopic dermatitis during preconception, pregnancy and lactation period.

Atopic dermatitis (AD) is a common inflammatory skin disease that affects both children and adults, including a large number of adults of reproductive age. Several guidelines for the treatment of AD exist, yet specific recommendations for the treatment of pregnant or lactating women and for adults planning to have a child are often lacking. This position paper from the European Task force on Atopic Dermatitis (ETFAD) is based on up-to-date scientific literature on treating pregnant and lactating women as wells as adults with AD planning to have a child. It is based on the expert opinions of members of the ETFAD and on existing safety data on the proposed treatments, many of which are derived from patients with other inflammatory diseases or from transplantation medicine. For treating future parents, as well as pregnant and lactating women with AD, the use of topical treatments including moisturizers, topical corticosteroids, tacrolimus, antiseptics such as chlorhexidine, octenidine, potassium permanganate and sodium hypochlorite (bleach) is deemed to be safe. Ultraviolet (UV) therapy may also be used. Systemic treatment should be prescribed only after careful consideration. According to the opinion of the ETFAD, treatment should be restricted to systemic corticosteroids and cyclosporine A, and, in selected cases, azathioprine.

Atopic dermatitis - all you can do from the outside.

Atopic dermatitis (AD) affects both the epidermal barrier and the immune system and, as such, therapy needs to address both. Skin cleansing supported by emollients and moisturizers is the primary topical therapy when treating patients with AD. However, it should be remembered that the direct use of emollients on inflamed skin is poorly tolerated and that the flares need to be treated effectively, usually by topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI). This contribution outlines a number of strategies for effectively managing AD, from reactive therapy using TCS and TCI to proactive therapy. Proactive therapy is an alternative, evidence-based, immunologically founded treatment approach, based on the fact that normal-looking, nonlesional skin of patients with AD is not normal. The advantage of the proactive approach is that the patients are in control of their disease and are actively involved in its management. The avoidance of external irritants is recommended wherever possible.

Beta-blockers for hemangiomas.

Infantile hemangiomas (IHs) are the most common tumors in infancy. Their typical natural history is characterized by an early rapid growth in the first months of life and by a slow spontaneous involution in the first years of life. Even though spontaneous regression of IHs could suggest therapeutic abstention, systemic treatment is the therapy of choice in many patients in which these situations occur: 1) rapid growth of IHs; 2) location of IHs in aesthetically critic areas; 3) recurrent hemorrhages, ulcerations or infections of IHs; 3) IHs interfering with important physiological functions (breathing, feeding, vision, hearing, etc.); 4) large or multicentric IHs that can cause heart failure. Since 2008, systemic administration of propranolol, an old non­selective ß­blocker, was found, serendipitously, to improve the treatment of IHs replacing older and more dangerous therapies like oral steroids, vincristine, interferon­alpha or vascular lasers. At present, oral propranolol has dramatically changed the approach of IHs because its efficacy is almost 100% and its action is rapid, without important side effects. The formal approval by FDA and EMA has been obtained in Spring 2014.

The European TREatment of severe Atopic eczema in children Taskforce (TREAT) survey.

BACKGROUND: There is a paucity of evidence for the use of systemic agents in children with atopic eczema refractory to conventional therapy, resulting in considerable variation in patient management. OBJECTIVES: The European TREatment of severe Atopic eczema in children Taskforce (TREAT) survey was established to collect data on current prescribing practice, to identify factors influencing the use of specific systemic agents, and to inform the design of a clinically relevant intervention study. METHODS: Consultant physician members of the paediatric dermatology societies and interest groups of eight European countries were invited to participate in a web-based survey. The multiple-response format questionnaire collated data on clinical practice in general, as well as detailed information on the use of systemic agents in refractory paediatric atopic eczema. RESULTS: In total, 343/765 members (44·8%) responded to the invitational emails; 89·2% were dermatologists and 71% initiate systemic immunosuppression for children with severe atopic eczema. The first-line drugs of choice were ciclosporin (43·0%), oral corticosteroids (30·7%) and azathioprine (21·7%). Ciclosporin was also the most commonly used second-line medication (33·6%), with methotrexate ranked as most popular third choice (26·2%). Around half of the respondents (53·7%) replied that they routinely test and treat reservoirs of cutaneous infection prior to starting systemic treatment. Across the eight countries, penicillins were the first-line antibiotic of choice (78·3%). CONCLUSIONS: In the absence of a clear evidence base, the European TREAT survey confirms the wide variation in prescribing practice of systemic immunosuppression in refractory paediatric atopic eczema. The results will be used to inform the design of a randomized controlled trial relevant to patient management across Europe.

Anemic nevus in neurofibromatosis type 1.

Anemic nevus (AN) is a congenital-vascular anomaly of the skin. Although it is a benign and asymptomatic lesion, it could be a frequent 'cutaneous finding' in neurofibromatosis type 1 (NF1). We performed a retrospective analysis to detect the prevalence of AN in all children with a presumptive diagnosis of NF1 treated in our center.

Multiple cutaneous and hepatic infantile hemangiomas having a successful response to propranolol as monotherapy at neonatal period.

Infantile hepatic hemangioma (IHH) is a common liver tumors of infancy with a higher incidence in females. Various treatments for infantile hepatic hemangioma such as systemic corticosteroids, interferon-alpha, vincristine and cyclophosphamide have been suggested, though no consensus exists about the first-choice treatment. Recent evidences suggest that propranolol, a nonselective ß-blocker, may be effective and safe as first-line therapy for infantile hepatic hemangioma. We report a case of female born at term with a weight of 2.450 g started to develop multiple cutaneous IHs at 10 days of age and presenting concomitant multiple cutaneous and hepatic infantile hemangiomas confirmed on magnetic resonance imaging. Propranolol, used as monotherapy, was started at 14 days of age at a dose of 2 mg/kg/day orally and maintained for 6 months. Patient was monitored in the hospital during first days of treatment with propranolol, and discharged after no side-effects were detected. Hepatic and cutaneous lesions had complete resolution in three months, although the fibro-fatty residuum of largest cutaneous nodule was still palpable at month 6. A further control after 6 months showed no recurrences. Our report case suggests that propranolol can be a safe and effective first-line therapy for neonates with concomitant multiple cutaneous and hepatic infantile hemangiomas.

Tumor lysis syndrome after propranolol therapy in ulcerative infantile hemangioma: rare complication or incidental finding?

A 33-day-old female with an ulcerated infantile hemangioma (IH) undergoing oral therapy with propranolol 2 mg/kg per day developed hyperkalemia and hyperphosphatemia 24 h after starting medication. No electrocardiographic or clinical abnormalities secondary to the electrolyte changes were noticed. A laboratory tumor lysis syndrome (TLS) was diagnosed after excluding other causes of electrolyte imbalance in the diagnostic workup. No treatment was required to reverse the TLS condition, and the propranolol therapy was continued as the electrolyte alterations were only mild. One month later, the IH was remarkably reduced in size and no longer ulcerated. Maintenance of propranolol was extended for a total of 6 months. Parallel to the gradual involution of the IH, serum potassium and phosphorus levels returned within normal levels. We suggest that TLS may be a rare complication of ulcerated IH treated with propranolol. Clinicians must be aware and order appropriate screening tests for TLS in patients at risk.

Guidelines for treatment of atopic eczema (atopic dermatitis) Part II.

The existing evidence for treatment of atopic eczema (atopic dermatitis, AE) is evaluated using the national standard Appraisal of Guidelines Research and Evaluation. The consensus process consisted of a nominal group process and a DELPHI procedure. Management of AE must consider the individual symptomatic variability of the disease. Basic therapy is focused on hydrating topical treatment, and avoidance of specific and unspecific provocation factors. Anti-inflammatory treatment based on topical glucocorticosteroids and topical calcineurin inhibitors (TCI) is used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, but the TCI tacrolimus and pimecrolimus are preferred in certain locations. Systemic immune-suppressive treatment is an option for severe refractory cases. Microbial colonization and superinfection may induce disease exacerbation and can justify additional antimicrobial treatment. Adjuvant therapy includes UV irradiation preferably with UVA1 wavelength or UVB 311 nm. Dietary recommendations should be specific and given only in diagnosed individual food allergy. Allergen-specific immunotherapy to aeroallergens may be useful in selected cases. Stress-induced exacerbations may make psychosomatic counselling recommendable. 'Eczema school' educational programs have been proven to be helpful. Pruritus is targeted with the majority of the recommended therapies, but some patients need additional antipruritic therapies.

[A new location of angiokeratoma circumscriptum]. / Une nouvelle localisation de l'angiokératome circonscrit næviforme.

BACKGROUND: Angiokeratomas are papular telangiectasias having a common histology of ectasia of the superficial dermal vessels surmounted by a hyperkeratotic epidermis. PATIENTS AND METHODS: The patient was a 9-year-old girl born of non-consanguineous parents after a well-followed pregnancy with problem-free delivery at term. From birth, she had a tumefaction of the left side of the nose and the left half of the upper lip that gradually increased in size without obstructing the nasal orifice and bled easily. Examination revealed the presence of tumefaction of the left nostril and the left half of the upper lip projecting towards the contralateral side especially in the nose. It was soft and painless, with the presence at the surface of dull red keratotic papules of 1 to 2 mm in diameter. Examination of the nasal mucosa revealed the same appearance of papules. DISCUSSION: Angiokeratoma circumscriptum is a rare congenital malformation, the rarest of five types. Since its initial description in 1890, few cases have been reported. However, female predominance has been noted with a male/female sex ratio of 1/3. It appears to be due to a genetic mutation that is probably autosomal, but the site of which is still unknown. In view of the special features of this case, several diagnoses were suggested, including Rendu Osler's disease, superficial lymphangioma and verrucous angioma. CONCLUSION: The particularity of this case is that it includes the first description of this site, which posed a therapeutic problem, especially concerning the choice of laser type to be used.

Atopic dermatitis (AD) management in an Italian pediatric clinic.

AIM: Atopic dermatitis (AD) is a common, chronic relapsing inflammatory skin disease characterized by dry skin and variable pruritus sometimes associated with allergic disease in other organs as asthma and rhinoconjunctivitis. AD affects deeply the Quality of Life, thus can be extremely disabling and may cause psychological problems for both affected children and their families. METHODS: In order to investigate the estimated prevalence of the disease and the beliefs of the Italian pediatricians, a group of 437 Italian family pediatricians covering a population of almost 380000 children participated in a study based on a questionnaire of 38 items. RESULTS: According to answers of the participants, the incidence of AD has been estimated around 10% of the population and food allergy is believed to be the trigger of the acute phase of the disease in infants. As a second opinion, dermatologists are consulted more frequently than allergologists. CONCLUSION: The use of emollients is advised in general whilst topical corticosteroids treatment is prescribed only in selected cases; more than 50% of pediatricians do not prescribe topical calcineurin inhibitors.

Patient-Oriented SCORAD (PO-SCORAD): a new self-assessment scale in atopic dermatitis validated in Europe.

BACKGROUND: Patient-oriented medicine is an emerging concept, encouraged by the World Health Organization, to greater involvement of the patient in the management of chronic diseases. The Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD) index is a self-assessment score allowing the patient to comprehensively evaluate the actual course of atopic dermatitis (AD), using subjective and objective criteria derived mainly from the SCORAD, a validated AD severity clinical assessment tool. OBJECTIVES: To validate the PO-SCORAD index in a large European population of patients exhibiting all forms of AD severity by assessing its correlation with the SCORAD index. PATIENTS/METHODS: Four hundred and seventy-one patients (185 adults, 286 children) consulting for AD in hospitals from 9 European countries were recruited. The investigators and the patients used the SCORAD and PO-SCORAD scales, respectively, to assess AD severity at inclusion (D0) and 28 ± 7 days later (D28). RESULTS: Patient-Oriented SCORing Atopic Dermatitis and SCORAD scores were significantly correlated at D0 [r = 0.67 (95% CI: 0.62; 0.72), P < 0.0001]. Consistency was confirmed at D28, with a stronger linear correlation between both scales [r = 0.79 (95% CI: 0.75; 0.83), P < 0.0001]. Absolute changes from baseline in SCORAD and PO-SCORAD scores were also significantly correlated [r= 0.71 (95% CI: 0.64; 0.76), P < 0.0001]. Although no specific intervention was investigated, AD improved over the study, with a decrease of PO-SCORAD and SCORAD scores from D0 to D28 by -19.19% and -24.39%, respectively. The consistency of the correlations was similar in the adult and children groups. CONCLUSIONS: This study validated the use of PO-SCORAD to self-assess AD severity and demonstrated its good correlation with SCORAD.
