Background:\ud \ud Actinic keratosis (AK) severity is currently evaluated by subjective assessment of patients.\ud Objectives:\ud \ud To develop and perform an initial pilot validation of a new easy-to-use quantitative tool for assessing AK severity on the head.\ud Methods:\ud \ud The actinic keratosis area and severity index (AKASI) for the head was developed based on a review of other severity scoring systems in dermatology, in particular the psoriasis area and severity index (PASI). Initial validation was performed by 13 physicians assessing AK severity in 18 AK patients and two controls using a physician global assessment (PGA) and AKASI. To determine an AKASI score, the head was divided into four regions (scalp, forehead, left/right cheek ear, chin and nose). In each region, the percentage of the area affected by AKs was estimated, and the severities of three clinical signs of AK were assessed: distribution, erythema and thickness.\ud Results:\ud \ud There was a strong correlation between AKASI and PGA scores (Pearson correlation coefficient: 0.86). AKASI was able to discriminate between different PGA categories: mean (SD) AKASI increased from 2.88 (1.18) for ‘light’ to 5.33 (1.48) for ‘moderate’, 8.28 (1.89) for ‘severe’, and 8.73 (3.03) for ‘very severe’ PGA classification. The coefficient of variation for AKASI scores was low and relatively constant across all PGA categories.\ud Conclusions:\ud \ud Actinic keratosis area and severity index is proposed as a new quantitative tool for assessing AK severity on the head. It may be useful in the future evaluation of new AK treatments in clinical studies and the management of AK in daily practice.

Porokeratosis ptychotropica (PP) is a rare variant of porokeratosis characterized by pruritic, symmetrical, red-brown verrucous papules, and plaques most commonly localized within the gluteal fold. Herein, we report the clinical, dermoscopy, and reflectance confocal microscopy (RCM) aspects of a case of PP in a 63-year-old Caucasian woman along with histopathological correlation. Both dermoscopy and RCM were able to recognize the cornoid lamella, the histopathological clue shared by all clinical variants of porokeratosis. These non-invasive techniques may help in the differential diagnosis with other inflammatory/infectious and neoplastic disorders that may clinically resemble PP, but show distinct patterns.

Background: Genetic and environmental components may contribute to acne causation. Objective: We sought to assess the impact of family history, personal habits, dietary factors, and menstrual history on a new diagnosis of moderate to severe acne. Methods: We conducted a case-control study in dermatologic outpatient clinics in Italy. Cases (205) were consecutive those receiving a new diagnosis of moderate to severe acne. Control subjects (358) were people with no or mild acne, coming for a dermatologic consultation other than for acne. Results: Moderate to severe acne was strongly associated with a family history of acne in first-degree relatives (odds ratio 3.41, 95% confidence interval 2.31-5.05). The risk was reduced in people with lower body mass index with a more pronounced effect in male compared with female individuals. No association with smoking emerged. The risk increased with increased milk consumption (odds ratio 1.78, 95% confidence interval 1.22-2.59) in those consuming more than 3 portions per week. The association was more marked for skim than for whole milk. Consumption of fish was associated with a protective effect (odds ratio 0.68, 95% confidence interval 0.47-0.99). No association emerged between menstrual variables and acne risk. Limitations: Some degree of overmatching may arise from choosing dermatologic control subjects and from inclusion of mild acne in the control group. Conclusions: Family history, body mass index, and diet may influence the risk of moderate to severe acne. The influence of environmental and dietetic factors in acne should be further explored.

AIM: The aim of this review was to evaluate, by a thorough revision of the literature, the true efficacy of currently available topic and systemic cosmetic acne agents. METHODS: The efficacy of currently available cosmetic acne agents has been retrospectively evaluated via thorough revision of the literature on matched electronic databases (PubMed). All retrieved studies, either randomized clinical trials or clinical trials, controlled or uncontrolled were considered. RESULTS: Scientific evidence suggests that most cosmetic products for acne may enhance the clinical outcome. Cleansers should be indicated to all acne patients; those containing benzoyl peroxide or azelaic/salicylic acid/triclosan show the best efficacy profile. Sebum-controlling agents containing nicotinamide or zinc acetate may minimize excessive sebum production. Cosmetics with antimicrobial and anti-inflammatory substances such as, respectively, ethyl lactate or phytosphingosine and nicotinamide or resveratrol, may speed acne recovery. Topical corneolytics, including retinaldehyde/glycolic acid or lactic acid, induce a comedolytic effect and may also facilitate skin absorption of topical drugs. Finally, the use of specific moisturizers should be strongly recommended in all acne patients. CONCLUSION: Cosmetics, if correctly prescribed, may improve the performance of the therapy, whereas wrong procedures and/or inadequate cosmetics may worsen acne. Cosmetological recommendations may allow clinicians to make informed decisions about the role of various cosmetics and to indentify the appropriate indications and precautions. The choice of the most effective product should take into consideration the ongoing pharmacological therapy and acne type/severity as well.

Treatment of plantar and periungueal warts (so called "difficult-to-treat" warts, DTW) and external genital warts (EGW) remains unsatisfactory. Medical or invasive procedures are partially effective and/or painful. Furthermore recurrences rates after treatments are still a relevant problem for all the available therapies. Nitric-zinc complex is a solution for topical application containing nitric acid, zinc, copper and organic acids able to induce a caustic effect of the wart trough mummification and proteins denaturation/coagulation action. Nitric-zinc complex has been shown to be an effective and well tolerated treatment of common warts.We evaluated in a prospective open label 4-centre trial, the efficacy and local tolerability of nitric-zinc complex in the treatment of EGW and DTW. A total of 37 immunocompetent subjects (20 men and 17 women; mean age: 45 years) with single or multiple lesions, were enrolled, after their informed consent. A total of 30 subjects had EGW, 2 subjects had plantar warts, 2 warts of the hand and 3 periungueal lesions. Nitric-zinc aqueous solution was applied topically using a 30 mL capillary tube over the lesions until a whitening/yellowish reaction appeared. A second (or more, if needed) application was performed at two-week interval until a complete clinical cure rate was observed. Primary outcome of the study was the clinical evaluation with picture documentation of the evolution of lesions classified as total cure, partial disappearance or no effect. Topical tolerability was evaluated through patient's reported adverse events.All subjects completed the study. A complete cure of lesions was observed in 31 subjects (90%) after one and up to four applications. Three patients with EGW (8%) showed a partial disappearance of lesions and one (2%) subject was no responder to four nitric-zinc complex applications. The product was well tolerated. No serious adverse events were observed or recorded.Nitric-zinc complex topical solution has shown to be an effective and well tolerated treatment of EGW and "difficult-to-treat" warts with a 90% of subjects with a total cure after one or up to four applications. A total or partial response was observed in 99% of the subjects. Nitric-zinc complex could be considered an easy-to-use effective treatment strategy of "difficult-to-treat" warts and external genital warts. Additional studies comparing nitric-zinc complex to other strategies are warranted.

Objective: To evaluate if nonprescription topical agents may provide positive outcomes in the management of mild-to-moderate facial seborrheic dermatitis by reducing inflammation and scale production through clinical evaluation and erythema-directed digital photography. Setting: Open-label, prospective, not-blinded, intra-patient, controlled, clinical trial (target area). Participants: Twenty adult subjects affected by mild-to-moderate facial seborrheic dermatitis were enrolled and instructed to apply the study cream two times daily, initially on a selected target area only for seven days. If the subject developed visible improvement, it was advised to extend the application to all facial affected area for 21 additional days. Measurement: Efficacy was evaluated by measuring the grade of erythema (by clinical examination and by erythema-directed digital photography), desquamation (by clinical examination), and pruritus (by subject-completed visual analog scale). Additionally, at the end of the protocol, a Physician Global Assessment was carried out. Results: Eighteen subjects completed the study, whereas two subjects were lost to follow-up for nonadherence and personal reasons, respectively. Day 7 data from target areas showed a significant reduction in erythema. At the end of study, a significant improvement was recorded for erythema, desquamation, and pruritus compared to baseline. Physician Global Assessment showed improvement in 89 percent of patients, with a complete response in 56 percent of cases. Conclusion: These preliminary results indicate that the study cream may be a viable nonprescription therapeutic option for patients affected by facial seborrheic dermatitis able to determine early and significant improvement. This study also emphasizes the advantages of using an erythema-directed digital photography system for assisting in a simple, more accurate erythema severity grading and therapeutic monitoring in patients affected by seborrheic dermatitis.

Background: Few data are available on the prevalence of common skin disorders like actinic keratoses in the general population. Such data are mostly needed to better define health needs and to organize medical services. The Prevalence of Actinic Keratoses in the Italian Population Study (PraKtis) was designed to estimate the point prevalence of actinic keratoses and related disorders, e.g. photoaging, in a representative sample of the Italian population. Within the study, information on the history of relevant dermatological diagnoses was also collected. Methods: The study was conducted in collaboration with DOXA, the Italian branch of the Gallup International Association. A representative sample of people aged 45 years or older was selected by picking them from the electoral rolls according to a stratified random sampling design involving a replacement procedure. A total of 180 interviewers specifically trained to collect data on skin diseases and to take photographs of representative lesions on the face and upper limbs, contacted and interviewed the sampled subjects and performed a face-to-face computer-assisted interview. A final sample of about 12,000 subjects was foreseen. Results: The pilot phase of the study was conducted between January 1 and June 30, 2003. A total of 3,660 subjects were recruited and interviewed. Overall, an estimated 37% of Italian people reported having ever undergone a dermatological consultation in the past. An estimated 29% reported having ever received a specific dermatological diagnosis by a physician. The frequency of specifically enquired diagnoses, weighted according to the distribution of the Italian population, was as follows: atopic dermatitis 4.7%, other eczematous dermatitides 4.3%, urticaria 4.3%, psoriasis 3.1%, skin tumors 1.6%, vitiligo 0.7% and actinic keratoses 0.3%. Conclusion: Skin diseases are frequently reported. The prevalence of actinic keratoses according to self-reported diagnoses was lower than expected based on prevalence data obtained by directly examining people. These discrepancies may be due to underreporting and/or unawareness of lesions by affected people. More precise estimates will be obtained by direct examination of sampled people.

The birth of what we now call plastic surgery dates to the fifteenth century, when the diffusion of nose amputation as a punishment was paralleled by the blossoming of surgical procedures for nose reconstruction. The relationship between the Eastern and the Western world fostered the spreading of the so-called Indian method, based on the use of a forehead flap. This technique was first introduced in Italy by the Branca family from Catania, Sicily. Eventually, a member of this family switched to a different approach to nose reconstruction using a cutaneous arm flap. This "Italian" method was followed and theorized by Tagliacozzi in Bologna. From the nineteenth century, distinguished surgeons like Sabattini, Tansini, Sterzi, Pieri, and more recently, Sanvenero Rosselli, with their pioneering work, substantially improved and helped develop plastic surgery in Italy as we know it today.

Background. Acne vulgaris is a common skin disease with a great impact on quality of life.Differences in latitude and sun exposure can totally change the characteristics of the disease. No universally accepted epidemiologic data are currently available. Objective. The aim of this study is to collect epidemiological data about acne, its severi- ty and its management during the summer months in different ethnic groups of the Mediterranean area. Methods. We analysed 355 acne patients (198 Italian, 85 Egyptian and 72 Croatian), between the ages of 12 and 40, and interviewed 80 dermatologists (40 Italian, 20 Egyptian, 20 Croatian) about their habitual therapeutic protocols. A group of expert der- matologists developed a questionnaire for acne patients to gather epidemiologic data and to assess their attitude towards therapy during summertime. Another questionnaire was created for dermatologists, to evaluate their approach to acne management and treat- ment during the summer. Results and discussion. Our results show that summer is an important period for the man- agement of acne in these three countries: a lot of differences in behaviour among patients were registered. Egyptian patients tend to continue therapy during the summer compared to Italian and Croatian patients.

Objective:To evaluate the efficacy and tolerability of a novel hydrogen peroxide-based regimen versus a benzoyl peroxide-based regimen in mild-to-moderate acne. Methods: In this eight-week multicenter study, patients were randomized to either a hydrogen peroxide-based or a benzoyl peroxide-based regimen.The primary outcome measure of clinical response was assessed using the Global Acne Grading System (GAGS) at baseline,four weeks, and eight weeks. At Week 8, a patient self-satisfaction questionnaire was administered. Investigators were also queried at that time regarding assessment of tolerability and cosmetic acceptability. Tolerability was also measured at each visit. Results: Both treatment regimens were associated with improvement of GAGS score at Week 8 compared to baseline (p
