Sun exposure and melanoma prognostic factors.

Previous studies have reported an association between sun exposure and the increased survival of patients with cutaneous melanoma (CM). The present study analyzed the association between ultraviolet (UV) light exposure and various prognostic factors in the Italian Clinical National Melanoma Registry. Clinical and sociodemographic features were collected, as well as information concerning sunbed exposure and holidays with sun exposure.

Sensitization to Formaldehyde in Northeastern Italy, 1996 to 2012.

Background: Formaldehyde is a widely used organic compound, used in several applications (hard thermoset resins, adhesives, disinfectants, tissue fixatives, etc), in its free form or released by formaldehyde releaser products. Its use is under control due to its toxic, carcinogenic, and allergenic properties.

Objective: The aim of this study was to investigate the frequency of formaldehyde sensitization, time trend, and correlation to occupations.

Occupational sensitization to epoxy resins in Northeastern Italy (1996-2010).

Background: One of the main health concerns of epoxy resins is their role as skin sensitizer. This sensitization is not uncommon, because the prevalence ranges around 1-12% of the general population.

Objectives: Perform a cross sectional study in a patch test population from Northeastern Italy to investigate the prevalence of epoxy resins sensitization among patients with suspected contact dermatitis.

In situ malignant melanoma on nevus spilus in an elderly patient.

Nevus spilus is the term usually given to a pigmented skin lesion, congenital or acquired, that may occur anywhere on the body, consisting of a large light tan patch with numerous superimposed darker scattered maculae or papulae that are flat or slightly raised. For a long time, nevus spilus was believed to be a benign lesion. However, in 1957 Perkinson reported a melanoma appearing on nevus spilus for the first time.

Erosive pustular dermatosis of the scalp induced by imiquimod.

Erosive pustular dermatosis of the scalp (EPDS) is a rare condition characterized by sterile pustules, erosions, and crusted lesions on the scalp of elderly patients. This inflammatory disorder has an unknown origin and it could develop into areas of alopecia that tend to be atrophic. An 84-year-old Caucasian man presented with a several months history of painful erythematous erosions and crusts on his scalp.

Nickel, chromium and cobalt sensitization in a patch test population in north-eastern Italy (1996-2010).

Background: Sensitization to nickel, cobalt and chromium is frequent in patch test populations. The prevalence is affected by geographical and socio-cultural factors.

Objectives: To investigate the temporal trend of nickel, cobalt and chromium contact sensitization between 1996 and 2010 in north-eastern Italy.

Concurrent sensitization to metals and occupation.

Background: Cosensitization to nickel, cobalt and chromium occurs in the general population and in some occupational groups.

Objectives: To estimate the isolated and concurrent occurrence of nickel, cobalt and chromium contact sensitization and their association with individual and occupational risk factors.

Patients/methods: Twelve thousand four hundred and ninety-two patients were patch tested with the European baseline series between 1997 and 2004 in north-eastern Italy.

p-Phenylenediamine sensitization and occupation.

Background: p-Phenylenediamine (PPD) is an extreme delayed-type skin sensitizer, and is relevant in both occupational and non-occupational exposures.

Objectives: To estimate the prevalence of PPD sensitization in a population of consecutive patients with suspected allergic contact dermatitis who attended units of dermatology or occupational medicine in north-eastern Italy and to investigate the association between their PPD sensitization and occupation.

Patients/materials/methods: A total of 14,464 patients (67.

Allergic contact sensitivity in elderly patients.

Background And Aims: Aging has been shown to be correlated with the rate and type of contact sensitization, but only a few studies have evaluated patch test reactivity in elderly subjects with an adequately large population.
