A systematic review of the safety of topical therapies for atopic dermatitis.

BACKGROUND: The safety of topical therapies for atopic dermatitis (AD), a common and morbid disease, has recently been the focus of increased scrutiny, adding confusion as how best to manage these patients. OBJECTIVES: The objective of these systematic reviews was to determine the safety of topical therapies for AD. METHODS: Databases searched included: OVID Medline, Medline In-Process and Other Non-Indexed Citations, Embase, and the Cochrane Central Register of Controlled Trials. In addition to the articles identified by this search, investigators were also referred to a list of links (most recently updated 25 September 2005) to recent Food and Drug Administration (FDA) studies, reports and meetings regarding the topical calcineurin inhibitors for further potential references. Only fully published papers available in English and data obtained from FDA sites were included. Furthermore, the criteria for inclusion and exclusion for each systematic review were further evaluated at a meeting of all of the content and evidence-based medicine experts participating in this process and alteration of the inclusion criteria was done at that time when it was felt necessary to avoid inclusion of lower-quality data in the review. Qualitative review of the abstracted data was performed and reviewed at a meeting of all of the content and evidence-based medicine experts. RESULTS: While systemic exposure to these topical agents does occur, physiological changes appear to be uncommon and systemic complications rare and have only been found with use of topical corticosteroids. CONCLUSIONS: Based on the data that are available the overall safety of AD therapies appears to be good with the only documented systemic side-effects of therapy those occasionally seen with use of topical corticosteroids.

Small facial haemangioma and supraumbilical raphe--a forme fruste of PHACES syndrome?

We report two female infants with congenital midline supraumbilical raphes who subsequently developed haemangiomas on the lower lip and gingiva within the first 2 months of life. One was found to have a subglottic haemangioma during laryngoscopy. The infants were otherwise well and had normal chest X-ray, echocardiogram, cranial ultrasound, magnetic resonance imaging/angiography (head, neck, chest) and ophthalmological examination. Both received oral prednisolone 1-2 mg kg(-1) daily and four sessions of flashlamp pulsed-dye laser therapy to the lip lesions, with significant improvement. The initial presentation of these two infants with supraumbilical raphes, who were otherwise healthy and without other cutaneous stigmata, suggested the diagnosis of isolated congenital sternal malformation. However, lower lip and gingival haemangiomas developed 4-6 weeks later, consistent with the diagnosis of PHACES syndrome. Children with sternal malformation and haemangioma may also have intracranial and/or cardiovascular anomalies. All previously reported patients were females who had either craniofacial and/or multiple haemangiomas. We propose guidelines for the evaluation and management of a neonate presenting with a sternal fusion defect at birth.

Disseminated linear calcinosis cutis associated with the Koebner phenomenon in an infant with congenital acute monocytic leukaemia.

We present a unique case of an infant with acute monocytic leukaemia who presented at birth with multiple rubbery, erythematous to violaceous subcutaneous nodules secondary to leukaemia cutis. As these infiltrates regressed with chemotherapy, numerous white to yellow linear confluent papules appeared in a scratch-like pattern. These lesions were widely disseminated but were concentrated across her face, trunk and extremities with relative sparing of the napkin area and back. We propose that these lesions represent a form of dystrophic calcinosis cutis that occurred secondary to koebnerization in an infant with congenital leukaemia cutis.

Validation of the Eczema Area and Severity Index for atopic dermatitis in a cohort of 1550 patients from the pimecrolimus cream 1% randomized controlled clinical trials programme.

OBJECTIVE: To validate the Eczema Area and Severity Index (EASI) by assessing its internal consistency, reliability and sensitivity to change and by correlating it to other efficacy parameters. DESIGN: Three short-term and two long-term double-blind, randomized, controlled trials, performed in 138 study centres in Europe, South Africa, Australia, New Zealand, and North and South America. PATIENTS AND METHODS: In total, 1550 paediatric patients with atopic dermatitis were studied. Pimecrolimus cream 1% was used twice daily to treat atopic dermatitis. The three short-term studies were placebo controlled. The two long-term studies evaluated the efficacy and safety of early intervention with pimecrolimus to prevent progression to disease flare requiring topical corticosteroid treatment, compared with reactive treatment with topical corticosteroids to treat flares of atopic dermatitis. MAIN OUTCOME MEASURES: Five parameters were measured: (i) the EASI (range of score 0-72); (ii) Investigators' Global Assessment (IGA), using a six-point (0-5) scale; (iii) patients' assessment, using a four-point (0-3) scale; (iv) severity of pruritus assessment, using a four-point (0-3) scale; and (v) a quality-of-life evaluation. RESULTS: The EASI score varied in parallel and in correlation with the IGA, pruritus and patients' assessment. All correlation coefficients were statistically different from 0 (P < 0.05). The EASI correlated well with each of its components, and all paired comparisons were within agreed limits. The EASI showed good sensitivity to changes in severity. CONCLUSION: In a large, multinational patient population with atopic dermatitis, the EASI showed good validity, reliability and sensitivity to change and correlated well with other measures of severity. It therefore qualifies as a valid method of assessment in clinical studies of atopic dermatitis.

Pimecrolimus 1% cream (Elidel) for atopic dermatitis.

Pimecrolimus is an immunomodulating medication that inhibits production of inflammatory cytokines in the skin and this compound was specifically developed for the treatment of inflammatory skin diseases. Phase II and III clinical trials with the topical formulation of pimecrolimus (Elidel cream, Novartis) have shown that it is safe and effective for use in patients with atopic dermatitis (AD). The US FDA recently approved Elidel for use in patients >or=2 years of age and older with mild to moderate atopic dermatitis (AD).

A prospective comparison of octyl cyanoacrylate tissue adhesive (dermabond) and suture for the closure of excisional wounds in children and adolescents.

BACKGROUND: Recent studies suggest that the use of octyl cyanoacrylate tissue adhesive for closure of both traumatic lacerations and incisional surgical wounds results in a cosmetic outcome comparable to that achieved with conventional sutures. To date, no studies have looked at the use of tissue adhesive for higher-tension wounds, such as those created during cutaneous excisional procedures. OBJECTIVE: To compare the tissue adhesive octyl cyanoacrylate with standard suture for the closure of excisional wounds in children and adolescents. DESIGN: A prospective comparison with blinded assessment of cosmetic outcome. Twenty-eight wounds were closed with monofilament suture and 24 were closed with tissue adhesive. At approximately 2 months, photographs of the incisions were evaluated by 2 dermatologists blinded to the method of skin closure. SUBJECTS: Forty-two consecutive patients undergoing excisional dermatologic procedures at Children's Hospital, San Diego, Calif. These 42 patients had a total of 52 wounds that were evaluated. MAIN OUTCOME MEASURES: The cosmetic appearance of the wounds at 2 months, based on 2 validated wound scales: the Hollander Wound Evaluation Scale and a visual analog scale. RESULTS: There were no differences in early complications between the groups. The suture group scored higher on the visual analog scale (63.3 mm for suture vs 47.8 mm for tissue adhesive), and this difference was statistically significant (P =.02). The suture group also had a higher median score on the Hollander Wound Evaluation Scale, but this difference was not statistically significant (P =.09). CONCLUSION: The cosmetic outcome of cutaneous excisional surgery wounds closed with standard suturing was found to be superior to that of wounds closed with octyl cyanoacrylate.

Linkage disequilibrium narrows locus for venous malformation with glomus cells (VMGLOM) to a single 1.48 Mbp YAC.

Venous malformations with glomus cells are localised cutaneous lesions of vascular dysmorphogenesis. They are usually sporadic, but sometimes familial. Using five families, we mapped the locus, VMGLOM, to chromosome 1p21-p22. In order to refine this locus, spanning 4-6 Mbp, we then studied seven additional families. They exhibited linkage to VMGLOM and the combined lod score for all 12 families was 18.41 at theta = 0.0 for marker D1S188. We found a distinct haplotype shared by seven families, comprising seven alleles which are rare in the general population (P < 0.01). This indicates that the haplotype is identical by descent in all seven families, and hence the locus can be refined by inferring ancestral crossovers. Using this approach, we position the causative gene between two markers on the same non-chimeric YAC of 1.48 Mbp, a feasible size for positional cloning. As there is no known gene involved in vasculogenesis and/or angiogenesis in this YAC, the identification of the causative gene is likely to reveal a novel regulator or vascular development.

Pediatric anesthesia in dermatologic surgery: when hand-holding is not enough.

BACKGROUND: Dermatologic procedures in children may require the use of topical and local anesthetics, sedatives, and general anesthesia. OBJECTIVE: To review developments in topical and local anesthetics, sedatives, and general anesthesia relevant to dermatologic procedures in children. METHODS: Review of the medical literature. RESULTS: Topical anesthetics, including EMLA and liposome-encapsulated lidocaine cream, amethocaine, cetacaine, and benzocaine products may be useful for decreasing the pain of cutaneous procedures including intra-lesional lidocaine infiltration. A variety of sedative and hypnotic agents may be utilized for pediatric dermatology procedures, and guidelines for their appropriate use have been published. General anesthesia for dermatologic procedures in the pediatric population is appropriate for a variety of procedures including laser treatment of capillary malformations. CONCLUSION: A variety of anesthetic, analgesic, and sedatives may be useful for pediatric cutaneous surgery.

A 12-week study of tacrolimus ointment for the treatment of atopic dermatitis in pediatric patients.

The safety and efficacy of 0.03% and 0.1% tacrolimus ointment for the treatment of atopic dermatitis were evaluated in a 12-week, randomized, double-blind, vehicle-controlled study of 351 children 2 to 15 years of age with moderate to severe atopic dermatitis. The mean age of patients was 6.1 years. A total of 61.5% of patients had severe atopic dermatitis at baseline. The mean percentage of body surface area affected was 47.7%, and 83.5% of patients were affected on the head and/or neck. Significantly more patients (P<.001) achieved clinical improvement of 90% or better with 0.03% or 0.1% tacrolimus ointment compared with vehicle. Significant improvements in the signs and symptoms of atopic dermatitis, percent body surface area affected, and the patient's assessment of pruritus were also observed early in treatment and were maintained throughout the study. Adverse events with a statistically significantly greater incidence in the 0.03% tacrolimus ointment treatment group compared with vehicle were limited to the sensation of skin burning, pruritus, varicella, and vesiculobullous rash ("blisters"). Varicella and vesiculobullous rash occurred at a low incidence (<5%). No adverse event occurred at a statistically higher incidence in the 0.1% tacrolimus ointment-treated group compared with vehicle. Tacrolimus ointment was equally safe for younger (2-6 years) and older (7-15 years) children. Both tacrolimus ointment concentrations (0.03% and 0.1%) were safe and significantly more effective than vehicle for the treatment of atopic dermatitis in children.

Compliance with federal and state legislation by indoor tanning facilities in San Diego.

BACKGROUND: The prevalence rates of both skin cancers and indoor tanning among the US population are high and have increased substantially in recent years. Low compliance by indoor tanning facilities with safety regulations may place consumers at greater risk of skin and ocular damage. OBJECTIVE: This study quantified the level of compliance by indoor tanning facilities with selected federal and state regulations and recommendations. METHODS: Tanning facilities (N = 54) in San Diego County, California, were visited by a confederate posing as a prospective customer. Compliance with 13 regulations/recommendations were assessed by either direct query or observation of the presence/absence of signs and warning labels. Operators' responses to 5 risk-based questions also were noted. RESULTS: No facility complied with all 13 regulations/recommendations. Compliance with 3 protective eyewear regulations was high (89%-100%). In contrast, compliance with maximum tanning frequency recommendations (approximately 6%) and parental consent regulations (approximately 43%) was disturbingly low. CONCLUSION: The investigators recommend instituting mandatory, comprehensive training for operators, as well as systematic compliance monitoring with enforcement of penalties for noncompliance.

Vascular and pigmented birthmarks.

Vascular and pigmentary lesions compromise most birthmarks. Lesions range from uncommon, to very common, some being essentially normal variants. The natural history of these varies from being transient phenomena of no significance to permanent cutaneous findings that may be associated with significant systemic complications or diseases. This article describes the most frequently encountered clinically important birthmarks, including congenital nevi, hypopigmented lesions, vascular malformations and hemangiomas, discussing clinical presentation, diagnosis, and findings that should prompt early assessment and treatment.

A national survey of sun safety activities at U.S. zoos.

Skin cancer incidence in the United States has increased. Exposure to ultraviolet radiation (UVR) is a major risk factor for skin cancer. Every year, millions of children with their families visit outdoor leisure facilities such as zoos where overexposure to UVR may occur. This study was conducted to assess the proportion of U.S. zoos that provided sun safety activities during the summer of 1998 and their willingness to incorporate skin cancer prevention strategies at their facility in the future. A 56 item self-administered questionnaire was mailed to 140 zoos accredited by the American Zoo and Aquarium Association. A follow-up telephone survey was also conducted with 33 mail non-respondents. The response rate was 97% (N = 136). Results revealed that in the summer of 1998, only 5% of zoos provided sun safety recommendations to visitors and 25% of zoos provided recommendations to their employees. The recommendations made most often to visitors and employees were to use sunscreen and wear protective clothing. Eighty-five percent of zoos indicated interest in providing sun safety activities at their facilities in the future. The next step will be to design environmentally appropriate sun safety programs for zoos and to encourage zoos to implement these programs.
