Prevalence of common and atypical melanocytic nevi in young adults and its relationship with sun protection and exposure habits.

Unlabelled: Background: The incidence of melanoma in young adults is rising. The design of appropriate preventive measures requires the analysis of risk factors, including the prevalence of common and atypical melanocytic nevi (MN) and sun protection and exposure habits.

Objectives: To establish the prevalence and density of common and atypical MN in young adults (18-25 yrs) and their relationship with sun exposure and protection habits.

Distribution pattern of psoriasis affects sexual function in moderate to severe psoriasis: a prospective case series study.

Introduction: Psoriasis may significantly impair sexual function. Depression and organic factors appear to play a key role in this relationship. However, beyond genital psoriasis, the importance of the distribution pattern of the disease has not been considered.

Variables associated with sun protection behaviour of preschoolers.

Little research has been published on the variables associated with sun protection behaviour in preschoolers. We aimed to define variables associated with sun protection behaviour of a sample of Spanish preschoolers. A cross-sectional observational study was conducted in two stages: 1) the design and validation of the measurement instrument, and 2) its application in a final sample of 100 (60 valid questionnaires) children for bivariate and multivariate binary logistic regression analyses of the data.

Androgenetic alopecia as an early marker of benign prostatic hyperplasia.

Background: Androgenetic alopecia (AGA) and benign prostatic hyperplasia are both androgen-dependent entities that respond to the blocking of 5-alpha-reductase.

Objectives: The objective of this study was to determine whether prostatic volumes and urinary flow changes were higher in patients with early-onset AGA than in healthy control subjects.

Methods: This was an observational case-control study of 87 men: 45 with early-onset AGA diagnosed in the dermatology department and 42 control subjects.

Homogeneous blue pattern: A rare presentation in an acral congenital melanocytic nevus.

Acral melanocytic nevi are relatively frequent in the palmoplantar location. In congenital nevi various characteristic dermoscopic patterns have been described, such as reticular and globular patterns, brown pigmented areas, and areas with peripilar depigmentation. However, there are few reports on the dermoscopic pattern of acral congenital nevi.

[Cutaneous necrosis due to interferon alpha in a patient with melanoma].

We present the case of a 55-year-old male with melanoma in the right retroauricular region who had cutaneous necrosis only in one of the injection sites after adjuvant treatment with interferon (IFN alpha 2b) according to the Kirkwood proposed regime. Appearance of cutaneous necrosis is a rare condition that has been described in patients treated with different types of IFN.

Amputation neuromas after neck surgery.

Traumatic or amputation neuromas are benign tumours formed by a proliferation of Schwann cells, axons and connective tissue elements. They are secondary to the partial or total section of a nerve pathway due to an accidental or surgical trauma. They can form at any site and affect any type of nerve.

Markers of metastasis in lip cancer.

The incidence of lip cancer in Granada, Spain, is much higher than that recorded in other countries. The natural history of the disease generally includes induction on previous actinic lesions, promotion with local growth of the tumour, and the appearance of metastasis in regional lymph node chains and, exceptionally, via the blood stream. In order to determine the risk factors for metastases, a retrospective hospital-based study was conducted of 251 cases of lower lip cancer diagnosed and treated during a 10-year period from 1985 to 1995.
