Prurigo nodularis (PN) is a benign neurodermatitis of unknown etiology characterized by firm, hyperkeratotic pruritic nodules most commonly localized symmetrically on the bilateral extensor lower extremities. PN represents a primary dermatological condition or a dermatological manifestation of repeated traumatic manipulation secondary to chronic pruritus. One must consider underlying causes of ...

Cryotherapy is the most common treatment for actinic keratosis, but its effect is limited to individual lesions. Several topical drugs, however, are available that, in addition to treating individual actinic keratoses, target field cancerization and thereby act on subclinical lesions. Examples are 5-fluorouracil, imiquimod, diclofenac, and ingenol mebutate. We report on 17 patients with actinic...

Topical treatment for actinic keratosis with 5% fluorouracil has a recurrence rate of 54% in 12 months of follow-up. This study analyzed thirteen actinic keratoses on the upper limbs through confocal microscopy, at the time of clinical diagnosis and after 4 weeks of treatment with fluorouracil. After the treatment was established and evidence of clinical cure was achieved, in two of the nine ac...

A 50-year-old gypsy woman presented with intense pruritus and skin lesions. She had controlled hypertension and Stage-4 chronic kidney disease with no hyperparathyroidism. No cholestatic disorder was observed. Physical examination revealed a papulonodular eruption on the limbs and the trunk and important lesions due to scratching. We consulted the dermatologist who prescribed sulpiride and a be...

The results of two methods retrieving actinic flux and ozone photolysis frequencies (JO1D), from measurements of irradiance with a Brewer MKIII spectroradiometer are investigated in this paper. The first method uses actinic flux retrieved from irradiance measurements by the use of known formulas while the second is an empirical method converting irradiance to JO1D through polynomials extracted ...

In September 2002, the first INSPECTRO campaign to study the influence of clouds on the spectral actinic flux in the lower troposphere was carried out in East Anglia, England. Measurements of the actinic flux, the irradiance and aerosol and cloud properties were made from four ground stations and by aircraft. The radiation measurements were modelled using the uvspec model and ancillary data. Fo...

Accepted: October 1, 2017 ABSTRACT It has been emphasized that prurigo simplex subacuta may be associated with various disorders and may be clinically confused with dermatitis herpetiformis. Aim of the study was to evaluate the value of our set of tests for finding possible associations and for the aforementioned differential diagnosis. Rates of implementations and abnormal results in our set o...

Photodynamic therapy (PDT) is an efficient treatment for actinic keratosis. A common problem, however, is pain. The aim of this study was to investigate pain during PDT for actinic keratosis. The possibility of using capsaicin cream for pain relief was also assessed. Pain was investigated during aminolaevulinic acid PDT in 91 patients. Size, redness, scaling and induration of the lesions were r...
