Key Communication Skills in Cosmetic Dermatology: A 3-Pillar Model. / Dermatología Estética: habilidades humanas claves en comunicación. Modelo de los tres pilares.

Cosmetic dermatology deals with the beauty and appearance of the skin - a most important element of body image. Treatments used in cosmetic dermatology (hygiene, hydration, protection, repair) aim to enhance the characteristics of the skin, its anatomy, its function, and its vitality, to produce aesthetic improvements. Communication with the patient is essential in medical consultations and we believe that it has special connotations in cosmetic dermatology that must be taken into account. In this article, we present a 3-pillar model for communication with cosmetic dermatology patients that rests on 3 skills: assertiveness, empathy, and critical judgement.

[A cross-sectional study of the impact of educational information on topical photoprotection habits in medical students]. / Estudio transversal sobre la repercusión de la información educativa en los hábitos de fotoprotección tópica en estudiantes de medicina.

OBJECTIVES: Skin cancer (melanoma and non-melanoma) is the most common cancer in humans, with melanoma being the most aggressive. Due to the fact that ultraviolet (UV) radiation exposure is the only adjustable aetiological factor, UV protection is the essential preventive measure. Based on these grounds, a study was conducted in order to compare three population groups with different levels of knowledge about UV protection, as well as to determine any differences in sun exposure habits, and the level of awareness of the damaging effects of the sun on the skin. MATERIALS AND METHODS: An observational, cross-sectional study was conducted using a questionnaire survey of 317 Spanish university students aged 18-25years old, between October and December 2015. Descriptive statistics methods and Pearson's Chi-squared were used. RESULTS: Six questions were used to evaluate the sun exposure habits. Significant differences were detected in two of them: mole self-assessment (P<.001) and the use of an appropriate sun protection factor (P=.025). Five questions were asked concerning the level of knowledge about UV protection, with differences (P<.001) being found in all cases. CONCLUSIONS: Despite having more knowledge about the risks of sun exposure in the medical dermatology students group, only two of the six habits questioned were improved. Other factors that could be involved are the aesthetic or sociocultural factors. The early prevention of skin cancer is essential, with health promotion programs needing to be established that take into account all these conditions.

Hair cosmetics: dyes.

Hair plays a significant role in body image, and its appearance can be changed relatively easily without resort to surgical procedures. Cosmetics and techniques have therefore been used to change hair appearance since time immemorial. The cosmetics industry has developed efficient products that can be used on healthy hair or act on concomitant diseases of the hair and scalp. Dyes embellish the hair by bleaching or coloring it briefly, for temporary periods of longer duration, or permanently, depending on the composition of a dye (oxidative or nonoxidative) and its degree of penetration of the hair shaft. The dermatologist's knowledge of dyes, their use, and their possible side effects (contact eczema, cancer, increased porosity, brittleness) can extend to an understanding of cosmetic resources that also treat hair and scalp conditions.

[Oral contraceptives in dermatology]. / Contracepción hormonal oral en Dermatología.

Patients with hyperandrogenic syndromes and diseases exacerbated by pregnancy and those taking common dermatologic drugs associated with risk to the fetus require prescription of contraceptives by the dermatologist. In healthy, nonsmoking women, oral contraception does not increase the risk of cerebral or cardiac vascular disease and is associated with major benefits besides avoiding pregnancy. These include prevention of ovarian and endometrial carcinoma, ectopic pregnancy, pelvic inflammatory disease, ovulation pain, and menstrual cycle disorders. This article will review the mechanism of action, side effects, health risks, contraindications, initiation of the oral contraceptive regimen, and patient follow-up, as well as interactions between contraceptives and other drugs.

[Sociodemographic characteristics of spanish skin cancer patients]. / Características sociodemográficas del cáncer cutáneo en España.

INTRODUCTION: Most epidemiological studies of skin cancer have been performed in countries with very different population and geographic characteristics to Spain. Investigation of this disease in the Spanish population would therefore be of interest. METHOD: Over a 12-month period, this prospective study recorded the types of skin cancer in consecutive patients who attended a dermatology clinic for the first time in health care area 3 of the health service of the Spanish autonomous community of Murcia. The demographic and social characteristics of these patients were determined. The results obtained were analyzed with the SPSS program, version 11.5, and compared with other studies conducted in other countries. RESULTS: Malignant tumors were the third most common presenting complaint (16.9 %) and the fourth most common secondary complaint (8 %). The patients with skin cancer were older (69.52 years; 95 % confidence interval [CI], 67.82-71.21 years) than the other patients in the sample (34.52 years; 95 % CI, 33.23-33.81 years), and there were more men (51.7 %) than women (48.3 %). These individuals had a low level of schooling, which varied according to the type of tumor, and most had outdoor jobs, with a significantly higher exposure to sunlight (3.35 h/d; 95 % CI, 3.08-3.62 h/d) than the other patients (2.72 h/d; 95 % CI, 2.58-2.86 h/d). Furthermore, fewer malignant cutaneous tumors were found in patients with a higher phototype. The length of time since onset of the presenting complaints was shorter for skin cancer (11.37 months; 95 % CI, 7.47-15.26 months) than for other skin diseases (25.83 months; 95 % CI, 22.87-28.80). Also, there were no seasonal peaks in consultations for skin cancer, and treatment was essentially based on surgery and cryotherapy. In addition, more of these patients had follow-up visits (84 %) than other dermatology patients (33 %). CONCLUSIONS: Malignant or premalignant skin lesions are a common presenting skin complaint in the Mediterranean region, with differences in terms of attendance rates and predominant tumor type compared to other countries. This is probably due to the high sun exposure and predominance of skin phototype III. Similar studies for the whole of Spain would be of interest.

Periocular vitiligo with onset around a congenital divided nevus of the eyelid.

Leukoderma in association with congenital melanocytic nevi is a rare phenomenon; nevertheless several reports have been published in the literature. We present a 15-year-old boy born with a pigmented lesion on the lower and upper eyelid diagnosed as a congenital divided nevus of the eyelid. At the age of 13, he developed a depigmented area around the nevus and was diagnosed at first as having a halo nevus in a congenital nevus. Over the next two years, an area of depigmentation appeared around the contralateral eye. At the present time, the patient has bilateral periocular depigmentation. Congenital divided nevus of the eyelid is a rare lesion, and no reports have been published to date of depigmentation in association with this lesion. Our patient presented with depigmentation around the nevus as in a halo nevus phenomenon, although at the present time, the depigmented area has a symmetric periocular distribution, and therefore can be labeled as periocular vitiligo associated with a congenital divided nevus.

Pustular generalized perforating granuloma annulare.

We report a 84-year-old man with a 13-year history of recurrent generalized asymptomatic pustular lesions. Histology revealed areas of necrobiosis surrounded by palisading granulomas and transepidermal and follicular elimination of the necrobiotic material. A dense infiltrate of neutrophils was also found. Although 26% of patients with generalized perforating granuloma annulare have some yellow pustule-like papules, these correspond histologically to the yellow viscous necrobiotic material extruding through the epidermis and not to a real neutrophilic infiltrate. This is the first case report of perforating granuloma annulare with recurrent generalized pustular lesions with a dense infiltrate of neutrophils.

[Acromelanosis]. / Acromelanosis.

Acromelanosis is an independent disease entity, characterized by increased skin pigmentation, usually located on the acral areas of the fingers and toes. It is mostly seen in newborns or during the first years of life. Only a few cases of this entity have previously been described in the medical literature. In some of these cases, the cutaneous lesions spread to affect large parts of the skin surface. A possible association with other benign and malignant diseases has been proposed. Differential diagnosis must be made with a wide variety of systemic and dermatologic conditions, especially dermatoses with acral distribution of macular hyperpigmentation, including acropigmentation. In this article, we report a new case of acromelanosis in a 5-week-old girl showing two peculiar clinical features: associated melanosis of the genital mucosa and stabilization of the lesions after an initial phase of progression and proximal spread. In addition, the most important features of this rare cutaneous disease are discussed.

[Hypohidrotic ectodermal dysplasia: A cause of fever of unknown origin]. / Displasia ectodérmica hipohidrótica: una causa de fiebre de origen desconocido.

The term ectodermal dysplasias includes many disorders that share some clinical features such as involvement of one or several ectodermal structures and congenital origin. Currently, 154 different types divided into 11 clinical subgroups (Freire Maia classification 1994) have been described. The most frequent entity is hypo- or anhidrotic ectodermal dysplasia (Christ-Siemens-Touraine syndrome). This is a rare hereditary disease whose main characteristic is the absence, or more often the reduction, of sweat glands, leading to an increase in body temperature together with anomalies of the epidermis and its appendages (hair and nails). We present a case of hypohidrotic ectodermal dysplasia in a premature 18-month-old boy who was referred to our department because of markedly dry skin since birth and recurrent eczematous and lichenification lesions that had been successfully treated with topical corticosteroids. Physical examination revealed mild alopecia with sparse and fine blonde hair and the absence of dental alveoli. The boy's mother had noticed slight sweating and episodes of fever without clinical symptoms, which were more frequent in summer. Hypohidrotic ectodermal dysplasia should be included in the differential diagnosis of fever of unknown origin.

Ichthyosis: the skin manifestation of multiple sulfatase deficiency.

Juvenile sulfatidosis (Austin type) or multiple sulfatase deficiency is an extremely rare autosomal recessive disorder affecting the activity of many sulfatases: arylsulfatase A, several mucopolysaccharide sulfatases, and steroid sulfatase. Certain aspects of the clinical phenotype can be attributed mainly to a deficiency of one specific sulfatase. Most patients develop metachromatic leukodystrophy caused by arylsulfatase A deficiency, dysostosis multiplex by mucopolysaccharide sulfatase deficiency, and ichthyotic skin by steroid sulfatase deficiency. We describe a 7-year-old boy with developmental delay from 7 months of age, progressive spastic quadriparesis, and coarse facial features. By 27 months of age, an ichthyotic rash had developed on the limbs, trunk, and scalp. A skin biopsy specimen revealed hyperkeratosis with a normal granular layer. The diagnosis of multiple sulfatase deficiency was demonstrated by measuring sulfatase activities in fresh leukocytes: there were large deficiencies of arylsulfatase A and B plus reduced arylsulfatase C. The ichthyosis associated with multiple sulfatase deficiency has an autosomal recessive inheritance, is caused by steroid sulfatase deficiency, and the scaling is sometimes milder than in X-linked recessive ichthyosis. This could reflect the residual activity of steroid sulfatase in some cases.
