ABSTRACT
El microtrasplante capilar, método FUE, es la cirugía para la recuperación capilar que consta en la extracción de unidades foliculares con punches de distintos diámetros y longitudes, desde una zona llamada dadora, generalmente occipital y/o temporal aunque pueden utilizarse otras partes del cuerpo como barba, tórax, abdomen y pubis, para luego de seleccionarse y conservarse en forma adecuada ser implantadas en la llamada zona receptora. Tanto los avances en la técnica como en el uso de instrumental de última generación generan resultados mejores y más naturales, con una recuperación más rápida y menor daño de sus zonas dadoras.
Hair transplant, FUE method, is surgery for hair recovery that consists of the extraction of follicular units with punches of different diameters and lengths, from an area called the donor; usually occipital and/or temporal; although they can be used on other parts of the body such as beard, thorax, abdomen and pubes. After being appropriately selected and preserved, they are implanted in the so-called receiving area. Both advances in technique and in the use of cutting-edge instruments generate better and more natural results, with faster recovery and less damage to the donor areas

Abstract The transforming growth factor-beta 1 (TGFβ1) promotes fibrosis, differentiating epithelial cells and quiescent fibroblasts into myofibroblasts and increasing expression of extracellular matrix. Recent investigations have shown that PPAR (peroxisome proliferator-activated receptor*) is a negative regulator of fibrotic events induced by TGFβ1. Dehydroepiandrosterone (DHEA) is an immunomodulatory hormone essential for PPAR functions, and is reduced in some processes characterized by fibrosis. Although scarring alopecia characteristically develops in the female biological period in which occurs decreased production of DHEA, there are no data in the literature relating its reduction to fibrogenic process of this condition. This article aims to review the fibrogenic activity of TGFβ1, its control by PPAR and its relation with DHEA in the frontal fibrosing alopecia.

Introduction: Body dysmorphic disorder (BDD) is excessive concern about physical appearance leading to mental, social & functional distress. Patients seek cosmetic surgery not psychiatry & may remain dissatisfi ed after surgery. Study includes 100 hair transplant patients. Materials and Methods: From 1st Jan to 31st July 2013. Patient’s Personal Evaluation, Yale Brown Obsessive Scale, Sheehan Lifestyle Disability Scale & Derriford Appearance Scale were used for evaluation. Patients deformities were corrected with hair transplant and these patients were reassessed. Results: 10 months later to judge the benefi t. BDD prevalence in hair loss is 28%, which is higher than rhinoplasty 20.7%. Preoccupation of hair loss on the minds of the patients is much higher than perceived by their doctors. After hair transplant 52% patients considered their baldness has been corrected, 32% patients, had milder perception of their defect but 16% continue to feel that they have less hair than others. Conclusion: Th e study shows that hair loss patients who display BDD like concerns, can have signifi cant benefi t in personal life, social life and work performance after hair transplant. Study also shows that four diff erent psychiatry scales can be used for evaluation and follow up of BDD in hair loss patients.

There has been a recent spurt in application of platelet-rich plasma (PRP) in dermatology and aesthetic medicine. However, the details regarding use of PRP in various dermatological indications ranging from hair restoration to chronic ulcers are dispersed in literature, herein we have tried to focus all under one heading. Overall, PRP seems to be a promising therapeutic modality but the level of evidence as of now, from the available published data is low. This review will also stimulate readers to carry out well designed, larger population based trials, so as to validate its use in dermatology practice.

En la actualidad, los procedimientos de radiología intervencional intracraneanos son cada vez más frecuentes. Sin embargo, la exposición a altas dosis de radiación durante la fluoroscopía puede inducir a complicaciones cutáneas como la alopecia transitoria post embolización, forma peculiar de radiodermatitis que afecta a las regiones del cuero cabelludo que reciben dosis más altas de radiación durante el proceso de embolización. El cuadro clínico se caracteriza por alopecia completa, no cicatricial, en parches con bordes bien delimitados y formas peculiares(rectángulos, círculos superpuestos), generalmente de localización occipital o en región temporo-parietal. Ocurre en promedio 2 a 4 semanas después del procedimiento endovascular, con repoblación del área alopécica a partir de las 4 a 5 semanas. Es de buen pronóstico y no requiere tratamiento específico. Es importante conocer este cuadro para poder orientar adecuadamente a los pacientes y alertar respecto a la incidencia de efectos adversos de la radiación terapéutica.
In the present, the neuroradiological procedures are more frequent. However, exposure to radiation can conduce to dermatological complication as transient alopecia after embolization, rare form of radiodermatitis that affect the areas of the scalp that receive highest doses of radiation. The clinical presentation is characterized by a complete alopecia, without any signs of inflammation of the scalp, with sharply defined patches in rare forms (rectangular, overlapped circles), generally located on occipital or temporo-parietal region. This phenomenon starts after 2 or 4 weeks since endovascular procedure, with hair re-growth after 4 or 5 weeks. It has good prognosis and no specific treatment is required. It is important to recognize this condition, in order to give adequate information to patients and warn about the incidence of adverse effects of therapeutic radiation.

Scalp hairs complete the body self-image and patients with alopecia suffer from overt disfi guration, leading to psychosocial embarrassment and signifi cant lack of self-esteem. Hence an early diagnosis and an aggressive treatment in the case of active hair loss are crucial in the management of scarring alopecia. This review presents a comprehensive study of newer theories in aetiopathogenesis, evolving diagnostic modalities and a step ladder approach in management of primary cicatricial alopecia.

Polycystic ovarian syndrome (PCOS) is a "multispeciality" disorder suspected in patients with irregular menses and clinical signs of hyperandrogenism such as acne, seborrhoea, hirsutism, irregular menses, infertility, and alopecia. Recently, PCOS has been associated with the metabolic syndrome. Patients may develop obesity, insulin resistance, acanthosis nigricans, Type 2 diabetes, dyslipidemias, hypertension, non-alcoholic liver disease, and obstructive sleep apnoea. Good clinical examination with hematological and radiological investigations is required for clinical evaluation. Management is a combined effort involving a dermatologist, endocrinologist, gynecologist, and nutritionist. Morbidity in addition includes a low "self image" and poor quality of life. Long term medications and lifestyle changes are essential for a successful outcome. This article focuses on understanding the normal and abnormal endocrine functions involved in the pathogenesis of PCOS. Proper diagnosis and management of the patient is discussed.

Desde los inicios de la humanidad el cabello ha tenido una importancia trascendental desde el punto de vista religioso, racial, sexual y ornamental. En los seres humanos el pelo es un vestigio evolutivo, a diferencia de otros seres vivos, que cumple funciones de protección y regulación de la temperatura. El número de pelos que se desprenden normalmente es de aproximadamente 100 por día y esta tasa aumenta al final del verano y principios de otoño, quizás debido a efectos de la mayor radiación solar y temperatura. La alopecia es la pérdida anormal del cabello, resultado de un proceso patológico. Las causas de alopecia son diversas y representan un desafío tanto para el médico como para el paciente. El objetivo de esta revisión es profundizar en la fisiopatología del cabello, las causas de alopecia y su tratamiento.
Hair has been always an important issue for humanity, from a religious, racial, sexual and ornamental point of view. In human beings hair is an evolution vestige. In other animals, hair serves to regulate body temperature and also has protective functions. Normally one hundred hairs fall in a day, and this rate increases by the end of summer and the first days of autumn, may be because of the more temperature end radiation. Alopecia is the abnormal loss of hair because of a pathologic process. The causes of alopecia are diverse, and they represent a challenge for the doctor and patient. The aim of this study is to deepen in the physiopathology of hair, causes of hair loss and their management.

Durante la adolescencia se producen cambios importantes en la piel que son motivo de consulta frecuente al especialista. Estos son producidos por múltiples factores, dentro de los cuales están los hormonales, inmunológicos, psicológicos y los psicosociales. Las dermatosis más frecuentes son: el acné, en sus distintas formas clínicas, que afecta a más del 90 por ciento de los adolescentes en distintos grados de severidad; la dermatitis seborreica; las alopecias no cicatriciales; hiperhidrosis y dishidrosis. Además, este grupo etáreo está presentando con mayor frecuencia complicaciones cutáneas por realizar arte corporal (perforaciones, tatuajes, entre otros). Estas dermatosis deben ser conocidas por los médicos generales y especialistas, porque los adolescentes son una población muy vulnerable psicológicamente y muchas de estas enfermedades van en detrimento de su calidad de vida. Las enfermedades cutáneas infecciosas (virales, bacterianas y parasitarias) que también comprometen a los adolescentes se analizarán en el capítulo sobre Infecciones Cutáneas.
Adolescent skin undergoes significant changes that may lead to frequent specialized consultation. These changes can be due to a number of factors such as physiological, hormonal and psychosocial changes. The most common skin diseases are acne in its various clinical forms which is suffered by over 90 per cent of teenagers at different levels of severity, seborreic dermatitis, non scarring alopecia, hyperhydrosis and dishydrosis and the skin complications originated by Body Art (tattooing, piercing, scarring andbranding), that are on the increase in this age group. General practitioners and specialist should be aware ofthese skin conditions since teenagers are psychologically vulnerable and many of these diseases have a negative effect on their lives. The infectious skin diseases (viral, bacterial an parasitic) which also affect adolescent will be reviewed in the Chapter related to skin infections.
