Histologically, a cupshaped epidermal invagination centred by a plug of epidermal hyperparakeratosis with suprabasal acantholysis and dyskeratosis is typically observed. A case of post-inflammatory WD, which was also observed by dermoscopy, is described. Dermoscopy showed an eight-shape whitish collarette surrounded by light brown pigmentation. A central white structureless area with an adjacent rosette were observed. Some small rust-coloured blood crusts were also observed in the centre of the lesion; no prominent vascular pattern was detected. The etiopathogenesis of this benign neoplasm could be multifactorial. Dermoscopy of WD is not specific but may help to ruling out other skin tumors.

We explored the role of personal and environmental factors in adult female acne. We conducted a multicenter case-control study in the outpatient departments of 12 Italian cities. Cases (n = 248) were consecutive women ≥25 years of age with newly diagnosed acne of any grade. Controls (n = 270) were females diagnosed with conditions other than acne. In multivariate analysis, a history of acne in parents (odds ratio [OR] = 3.02) or siblings (OR = 2.40), history of acne during adolescence (OR = 5.44), having no previous pregnancies (OR = 1.71), having hirsutism (OR = 3.50), being an office worker versus being unemployed or being a housewife (OR = 2.24), and having a high level of reported psychological stress (OR = 2.95) were all associated with acne. A low weekly intake of fruits or vegetables (OR = 2.33) and low consumption of fresh fish (OR = 2.76) were also associated with acne. We did not establish an onset date for acne. Some of our associations may reflect consequences of established acne. Lifestyle factors may play an important role for acne development in adulthood, but their role should be further assessed in prospective studies.

The aim of this study was to estimate the prevalence of several skin conditions among a sample that is deemed to be representative of the general population of young men living in southern Italy. Potential conscripts resident in the coastal regions of southern Italy and called at the age of 18 to the Draft's Council Medical Unit in Taranto underwent a clinical and instrumental examination to evaluate their psycho-physical fitness to compulsory service in Italian Navy. From January 1998 to April 2004 a dermo-epidemiologic project named EpiEnlist (EPIdemiology in ENLISTed Men) project was carried out by the Department of Dermatology of the Italian Navy Hospital in Taranto under the auspices of the Italian Group for Epidemiological Research in Dermatology. All the subjects showing skin lesions evocative of neurofibromatosis (NF), congenital melanocytic nevus (CMN), Becker nevus (BN), and vitiligo were referred to the Department of Dermatology of the Italian Navy Hospital for confirming the diagnosis. The confirmed cases were recorded in a predefined patient's card, containing the main anamnestic, clinical, instrumental, and laboratory data. Because the recording of the various conditions started and ended in different times, the total number of examined subjects varied. NF type 1 was diagnosed in 6 of 34 740 subjects [prevalence 1:5735 or 0.017%; 95% confidence interval (95% CI), 0.0008-0.0037], CMN in 157 of 23 354 (prevalence 1:148 or 0.67%; 95% CI, 0.57-0.79). BN was observed in 70 of 27 954 young men (prevalence 1:399 or 0.25%; 95% CI, 0.15-0.35), and its mean age of appearance was 11.9 years (minimum 5-maximum 17). In 41 subjects (58.6%), the age of appearance was over 10 years. Vitiligo was recorded in 60 of 34 740 persons (prevalence 1:579 or 0.17%; 95% CI, 0.13-0.22). In 40 subjects with vitiligo, the blood test was done: in 40% of these circulating autoantibodies, mainly anti-thyroid (25.6%) and anti-smooth muscle (17.3%) autoantibodies were detected, but only in 5% of cases, a thyroid disease was diagnosed, and no other sign of autoimmune diseases was observed. The epidemiological data of the skin conditions considered in the present study can be considered roughly in agreement with those reported in the available surveys. Because they were obtained in a large sample of Italian young males from the general population, they can be useful for therapeutic and preventive interventions by the public health organizations.

The aim of this report was to study the QoL in a sample of Italian vitiligo patients by using the Dermatology Life Quality Index (DLQI) questionnaire. A sample of forty seven vitiligo subjects, identified among 34,740 potential conscripts resident in southern Italy underwent the Italian version of the DLQI questionnaire. The median total DLQI score was 1 (IQR: 2; mean: 1.82). In univariate analysis, DLQI total score was significantly influenced by the clinical course of vitiligo, disease extension over the body, and location on face and/or hands. Multivariate analysis using logistic stepwise regression showed that only the localization on the hands and on the face influenced significantly the mean DLQI.

Therefore a distinction between 'extrinsic' or 'allergic' and 'intrinsic' or 'non-allergic' AD has been suggested. Recently, a patch test with environmental aeroallergens, named atopy patch test (APT), has been proposed for use in the study of AD. OBJECTIVE The aim of this study was to investigate the reactivity to APT in patients with 'extrinsic' and 'intrinsic' AD. Two groups of adult male subjects with AD were examined consecutively in our department (Department of Dermatology, Italian Navy Main Hospital, Taranto, Italy) andpatch tested with whole bodies of house dust mites (HDM) at a concentration of 20% in petrolatum (Dermatophagoides pteronyssinus 50%, D. farinae 50%). The groups included: (i) 95 patients affected by the adult clinical form of 'extrinsic' AD; (ii) 12 patients affected by the adult clinical form of 'intrinsic' AD; and (iii) a control group of 49 adult healthy male subjects with a negative anamnesis for eczema and atopy and negative skin prick test to aeroallergens/food allergens and/or normal level of total circulating IgE, also patch tested with the same allergen. The statistical differences were calculated by chi2 test and 95% confidence intervals (CI) were provided. The APT was positive in 47.4% (CI: 37-57%) of'extrinsic'AD, in 66.6% (CI: 41-93%) of'intrinsic' AD and in 12.2% (CI: 3-21%) of healthy subjects. The differences between the two AD subgroups and the control group were statistically significant (P < 0.001). APT positivity is more frequent in both 'extrinsic' and 'intrinsic' AD than in unaffected subjects. Other studies are needed to confirm our data and to explain why the APT is positive in the 'intrinsic' form.

The aim of this study was to evaluate the response to the APT with house dust mites (HDM) in subjects nonaffected by AD and to compare the outcomes observed in these cases with those pointed out in AD patients, evaluating also the differences between two allergen extracts manufactured at different purifications and concentrations. Forty-seven atopic subjects without eczema (AWE), 33 nonatopic (NA) subjects and 77 adult AD patients were patch tested with an extract of purified bodies of HDM at 20% and with another extract of whole bodies of HDM at 30%, the latter corresponding to 300 microg/g of Der p 1. The reproducibility of APT was also tested in 8 AD patients, in 37 AWE subjects and in 19 NA subjects. Positive responses with extract at 20% were observed in 29 (37.7%) AD, in 5 (10.6%) AWE and in 4 (12.1%) NA subjects. The APT with HDM at 30% was positive in 32 (41.6%) AD, 9 (19.1%) AWE and 4 (12.1%) NA persons. The rates of positivity and the intensity scores of responses were significantly different between AD and non-AD subjects (p < 0.01). The reproducibility of the APT in the three groups was satisfactory. These observations lead to conclude that the APT with HDM is positive also in non-AD subjects but it is probably more specific for AD.

The aim of this study was the assessment of the frequency of XLI in a large representative sample of the Italian male population. This study involved young men who enlisted as conscripts in the Italian Navy from January 1998 through February 2002, examined, prior to enlistment, at the Draft Council's Medical Unit of the Italian Navy in Taranto, Italy, to evaluate their psychophysical fitness. All the patients with an ichthyosiform condition were referred to the Department of Dermatology of the Navy Hospital, underwent a thorough dermatological examination and completed a questionnaire regarding their personal and familial history. Pertinent results of the other clinical investigations were recorded and the final diagnosis was formulated on the basis of all these data. From January 1998 through February 2002, of 75,653 young men examined, 15 cases of XLI were diagnosed, with a frequency of 1:5,043 or 1.98 per 10,000 (95% confidence interval based on the Poisson distribution 1.01-2.90). Four out of 15 cases (26.6%) showed corneal opacities. No other significant associated pathological change was observed. As this study is a survey involving a large male sample, homogeneous with reference to age, race and country of origin (southern Italy), the frequency of XLI could be estimated at about 1.98 per 10,000 males. These data are roughly in agreement with estimates from other European surveys.

The aim of this paper was to evaluate the prevalence and risk factors for superficial mycoses (dermatophytes and Candida spp.) in a sample of young Italian people resident at a military school. A total of 1,024 young cadets from the Italian Navy Petty Officers School in Taranto, including 975 (95.21%) males and 49 (4.79%) females, mean age 22.5 +/- 3.0 years (range 18-30), were consecutively examined by the same observer. A complete dermatological examination was performed on all the subjects, and skin scrapings for microscopy and fungal culture were obtained from suspected lesions. All the subjects completed a questionnaire providing information on sports practice, swimming-pool attendance, marching, wearing shower sandals, frequent use of 'gummed' shoes, history of severe traumas to the nails, presence of hyperhidrosis and history of superficial mycoses. The affected subjects were also asked if they were aware of their condition. Data were analysed by the Statistical Analysis System, version 8.0. The Fisher exact test and odds ratios were calculated. A total of 33 subjects (3.2%) were found to suffer from a mycologically confirmed fungal infection (3% by dermatophytes and 0.2% by Candida albicans): tinea pedis/Candida intertrigo of the feet was suspected in 126 (12.1%) subjects and confirmed in 30 (2.9%), including 28 cases of tinea pedis and 2 cases of Candida intertrigo; tinea cruris/Candida intertrigo of the groin was suspected in 28 (2.7%) subjects, but confirmed in only 1 case (0.1%); onychomycosis was suspected in 64 (6.1%) subjects and confirmed in 2 cases (0.2%). The organism most frequently responsible in tinea pedis was Trichophyton mentagrophytes var. interdigitale (82.1%). The same species (50%) and T. mentagrophytes var. mentagrophytes (50%) were associated with tinea unguium, Epidermophyton floccosum was the only species detected in tinea cruris. Non-dermatophytic filamentous fungi (Penicillium spp., Fusarium spp., Aspergillus spp. and Paecilomyces spp.), not considered pathogenic, were isolated in 48 samples. None of the risk factors analysed were significantly associated with fungal infection. Only 2 subjects out of the 33 people affected were aware of their condition. They both had tinea pedis. The prevalence of mycoses in sailors living in an Italian military school was lower than rates detected in other military populations. This may be due to the cadets' lifestyle and environmental conditions. The most frequent infection was tinea pedis, mainly caused by T. interdigitale. None of the investigated risk factors were significantly associated with the disease, and most of the affected individuals were not aware of their condition.

In the only available study from Italy the rate was 1% at birth and 1.4% at 2 years of age. Some surveys performed among samples of children and adolescents in other countries showed a prevalence which ranged from 1.4 to 4.4%. Additional data on the frequency in adults are not available. The aim of this study was to estimate the prevalence of CMN in a large sample of a young male Italian population, which is deemed to be representative of the general population of the same age and sex. The potential conscripts resident in the coastal regions of southern Italy, enlisted for the compulsory service in the Italian Navy, were called at the age of 18 to the Draft's Council Medical Unit of the Italian Navy in Taranto to evaluate their psychophysical fitness to recruitment. All the subjects examined from September 2002 to March 2004 showing skin lesions evocative of CMN were referred by general practitioners of the Draft's Council Medical Unit to the Department of Dermatology of the Italian Navy Hospital for confirming the diagnosis, which was based on the clinical features and the personal history. The confirmed cases were recorded in a predefined patient card, containing the main anamnestic and clinical data. Since the screening of small CMN in such a large sample of subjects was believed to be difficult, only CMN with a diameter >or=1.5 cm were recorded. In 23,354 examined persons 157 CMN were diagnosed, with a prevalence of 0.67% (Bayesian 95% confidence interval 0.57-0.79); 126 (80.3%) CMN were medium-sized (>or=1.5 and <or=19.9 cm in diameter), and 31 (19.7%) were large (>or=20 cm in diameter). Three CMN (1.9%) were located on the face, 23 (14.6%) on the chest, 24 (15.2%) on the abdomen, 36 (22.9%) on the back, 48 (30.5%) on the lumbar area, 15 (9.5%) on the upper limb, 19 (12.1%) on the lower limb and 15 (9.5%) on the shoulder. No CMN was located on the head. In 19 cases (12.1%) >or=2 adjacent anatomical sites (shoulder/chest, shoulder/arm, etc.) were involved. In 73 moles (46.4%) terminal hairs were present. Eight CMN (5.1%) showed a zosteriform (i.e. segmental) feature. None of the examined subjects reported a personal history of malignant melanoma (MM), and no person with a history of MM was observed among all the enlisted men referred to the Department of Dermatology during the time of the study. The prevalence of CMN in the Italian young male general population is roughly in agreement with the rates detected in general populations from other European studies. The observations of this study also suggest that the risk of appearance of MM, at least in childhood and adolescence, is limited for medium-sized CMN.

OBJECTIVE The aim of this study was to investigate the reactivity to APT in patients with 'extrinsic' and 'intrinsic' AD. Two groups of adult male subjects with AD were examined consecutively in our department (Department of Dermatology, Italian Navy Main Hospital, Taranto, Italy) andpatch tested with whole bodies of house dust mites (HDM) at a concentration of 20% in petrolatum (Dermatophagoides pteronyssinus 50%, D. farinae 50%). The groups included: (i) 95 patients affected by the adult clinical form of 'extrinsic' AD; (ii) 12 patients affected by the adult clinical form of 'intrinsic' AD; and (iii) a control group of 49 adult healthy male subjects with a negative anamnesis for eczema and atopy and negative skin prick test to aeroallergens/food allergens and/or normal level of total circulating IgE, also patch tested with the same allergen. The statistical differences were calculated by chi2 test and 95% confidence intervals (CI) were provided. The APT was positive in 47.4% (CI: 37-57%) of'extrinsic'AD, in 66.6% (CI: 41-93%) of'intrinsic' AD and in 12.2% (CI: 3-21%) of healthy subjects. The differences between the two AD subgroups and the control group were statistically significant (P < 0.001). APT positivity is more frequent in both 'extrinsic' and 'intrinsic' AD than in unaffected subjects. Other studies are needed to confirm our data and to explain why the APT is positive in the 'intrinsic' form.

The aim of this study was to evaluate the response to the APT with house dust mites (HDM) in subjects nonaffected by AD and to compare the outcomes observed in these cases with those pointed out in AD patients, evaluating also the differences between two allergen extracts manufactured at different purifications and concentrations. Forty-seven atopic subjects without eczema (AWE), 33 nonatopic (NA) subjects and 77 adult AD patients were patch tested with an extract of purified bodies of HDM at 20% and with another extract of whole bodies of HDM at 30%, the latter corresponding to 300 microg/g of Der p 1. The reproducibility of APT was also tested in 8 AD patients, in 37 AWE subjects and in 19 NA subjects. Positive responses with extract at 20% were observed in 29 (37.7%) AD, in 5 (10.6%) AWE and in 4 (12.1%) NA subjects. The APT with HDM at 30% was positive in 32 (41.6%) AD, 9 (19.1%) AWE and 4 (12.1%) NA persons. The rates of positivity and the intensity scores of responses were significantly different between AD and non-AD subjects (p < 0.01). The reproducibility of the APT in the three groups was satisfactory. These observations lead to conclude that the APT with HDM is positive also in non-AD subjects but it is probably more specific for AD.

The aim of this study was the assessment of the frequency of XLI in a large representative sample of the Italian male population. This study involved young men who enlisted as conscripts in the Italian Navy from January 1998 through February 2002, examined, prior to enlistment, at the Draft Council's Medical Unit of the Italian Navy in Taranto, Italy, to evaluate their psychophysical fitness. All the patients with an ichthyosiform condition were referred to the Department of Dermatology of the Navy Hospital, underwent a thorough dermatological examination and completed a questionnaire regarding their personal and familial history. Pertinent results of the other clinical investigations were recorded and the final diagnosis was formulated on the basis of all these data. From January 1998 through February 2002, of 75,653 young men examined, 15 cases of XLI were diagnosed, with a frequency of 1:5,043 or 1.98 per 10,000 (95% confidence interval based on the Poisson distribution 1.01-2.90). Four out of 15 cases (26.6%) showed corneal opacities. No other significant associated pathological change was observed. As this study is a survey involving a large male sample, homogeneous with reference to age, race and country of origin (southern Italy), the frequency of XLI could be estimated at about 1.98 per 10,000 males. These data are roughly in agreement with estimates from other European surveys.

The aim of this paper was to evaluate the prevalence and risk factors for superficial mycoses (dermatophytes and Candida spp.) in a sample of young Italian people resident at a military school. A total of 1,024 young cadets from the Italian Navy Petty Officers School in Taranto, including 975 (95.21%) males and 49 (4.79%) females, mean age 22.5 +/- 3.0 years (range 18-30), were consecutively examined by the same observer. A complete dermatological examination was performed on all the subjects, and skin scrapings for microscopy and fungal culture were obtained from suspected lesions. All the subjects completed a questionnaire providing information on sports practice, swimming-pool attendance, marching, wearing shower sandals, frequent use of 'gummed' shoes, history of severe traumas to the nails, presence of hyperhidrosis and history of superficial mycoses. The affected subjects were also asked if they were aware of their condition. Data were analysed by the Statistical Analysis System, version 8.0. The Fisher exact test and odds ratios were calculated. A total of 33 subjects (3.2%) were found to suffer from a mycologically confirmed fungal infection (3% by dermatophytes and 0.2% by Candida albicans): tinea pedis/Candida intertrigo of the feet was suspected in 126 (12.1%) subjects and confirmed in 30 (2.9%), including 28 cases of tinea pedis and 2 cases of Candida intertrigo; tinea cruris/Candida intertrigo of the groin was suspected in 28 (2.7%) subjects, but confirmed in only 1 case (0.1%); onychomycosis was suspected in 64 (6.1%) subjects and confirmed in 2 cases (0.2%). The organism most frequently responsible in tinea pedis was Trichophyton mentagrophytes var. interdigitale (82.1%). The same species (50%) and T. mentagrophytes var. mentagrophytes (50%) were associated with tinea unguium, Epidermophyton floccosum was the only species detected in tinea cruris. Non-dermatophytic filamentous fungi (Penicillium spp., Fusarium spp., Aspergillus spp. and Paecilomyces spp.), not considered pathogenic, were isolated in 48 samples. None of the risk factors analysed were significantly associated with fungal infection. Only 2 subjects out of the 33 people affected were aware of their condition. They both had tinea pedis. The prevalence of mycoses in sailors living in an Italian military school was lower than rates detected in other military populations. This may be due to the cadets' lifestyle and environmental conditions. The most frequent infection was tinea pedis, mainly caused by T. interdigitale. None of the investigated risk factors were significantly associated with the disease, and most of the affected individuals were not aware of their condition.

In the only available study from Italy the rate was 1% at birth and 1.4% at 2 years of age. Some surveys performed among samples of children and adolescents in other countries showed a prevalence which ranged from 1.4 to 4.4%. Additional data on the frequency in adults are not available. The aim of this study was to estimate the prevalence of CMN in a large sample of a young male Italian population, which is deemed to be representative of the general population of the same age and sex. The potential conscripts resident in the coastal regions of southern Italy, enlisted for the compulsory service in the Italian Navy, were called at the age of 18 to the Draft's Council Medical Unit of the Italian Navy in Taranto to evaluate their psychophysical fitness to recruitment. All the subjects examined from September 2002 to March 2004 showing skin lesions evocative of CMN were referred by general practitioners of the Draft's Council Medical Unit to the Department of Dermatology of the Italian Navy Hospital for confirming the diagnosis, which was based on the clinical features and the personal history. The confirmed cases were recorded in a predefined patient card, containing the main anamnestic and clinical data. Since the screening of small CMN in such a large sample of subjects was believed to be difficult, only CMN with a diameter >or=1.5 cm were recorded. In 23,354 examined persons 157 CMN were diagnosed, with a prevalence of 0.67% (Bayesian 95% confidence interval 0.57-0.79); 126 (80.3%) CMN were medium-sized (>or=1.5 and <or=19.9 cm in diameter), and 31 (19.7%) were large (>or=20 cm in diameter). Three CMN (1.9%) were located on the face, 23 (14.6%) on the chest, 24 (15.2%) on the abdomen, 36 (22.9%) on the back, 48 (30.5%) on the lumbar area, 15 (9.5%) on the upper limb, 19 (12.1%) on the lower limb and 15 (9.5%) on the shoulder. No CMN was located on the head. In 19 cases (12.1%) >or=2 adjacent anatomical sites (shoulder/chest, shoulder/arm, etc.) were involved. In 73 moles (46.4%) terminal hairs were present. Eight CMN (5.1%) showed a zosteriform (i.e. segmental) feature. None of the examined subjects reported a personal history of malignant melanoma (MM), and no person with a history of MM was observed among all the enlisted men referred to the Department of Dermatology during the time of the study. The prevalence of CMN in the Italian young male general population is roughly in agreement with the rates detected in general populations from other European studies. The observations of this study also suggest that the risk of appearance of MM, at least in childhood and adolescence, is limited for medium-sized CMN.
