RESUMEN
BACKGROUND: Mexican mestizo population has a pluriethnic mixture of Amerindian, European and African ancestry, predominant in most Latin American countries. Until now, there are no reports about hair characteristics in this population, necessary to define normal values, for hair diseases evaluation and comparison among other ethnic groups. METHODS: The VivoSight® swept-source multibeam optical coherence tomography system was used to evaluate hair diameter and shape in 30 females. Three hair samples from each volunteer were measured transversely along three distances, generating nine cross-sectional images, two measurements per image and 18 measurements per patient for a total of 540 diameter measurements. RESULTS: Minimum hair diameter (n = 540) was 0.06 mm while maximum was 0.14 mm. Mean diameter was 0.10 ± 0.01 mm as compared with Asian hair, which ranges from 0.08 mm to 0.12 mm. On morphological analysis, Mexican Mestizo hair tends to have a round shape with homogenous diameters, resembling Caucasian and Asian hair. CONCLUSION: Mexican hair is similar to Asian hair in diameter and shape and can be classified as 'thick' hair, which make it more resistant and with more volume. Cosmetic products intended to improve hair care in this population must to consider this characteristic.

The history of women in medicine has been marked by many challenges and achievements. Although the role of women in the "art of healing" can be traced back many centuries, only males are traditionally highlighted in history. Across antiquity, access to medical education was denied to females. Dermatology is a medical specialty in which women displayed particular skill and proficiency. Gradually, determination and competence allowed women to lay claim in an essentially male-dominated world. This article presents a brief review of the performance, progress and achievements of women in the history of medicine and dermatology.

The interaction between the mind and diseases of the skin has been the study focus for many researchers worldwide. The field of Psychodermatology, or Psychocutaneous Medicine, is the result of the merging of two major medical specialties, psychiatry and dermatology. Although the history of Psychodermatology is rather old and interesting, the field has only recently gained popularity. Since ancient times, philosophers, surgeons, dermatologists and psychiatrists have reported the presence of psychocutaneous diseases in various scenarios. In this article, the authors describe curious and remarkable facts in the history of Psychodermatology.

A técnica cirúrgica micrográfica de Mohs é modalidade muito útil para excisão de cânceres de pele de difícil manejo. Desde que corretamente realizada, oferece vantagens sobre os outros métodos de tratamento para malignidades cutâneas. O procedimento é dividido em etapas bem definidas: avaliação e marcação da lesão, exérese, preparação e mapeamento da peça cirúrgica, processamento e análise histológica e fechamento da ferida cirúrgica. A avaliação histológica de todas as margens cirúrgicas leva a maiores taxas de cura e maior conservação tecidual, conferindo ao procedimento segurança e confiabilidade.
