Objectives To better categorize the epidemiologic profile, clinical features, and disease associations of loose anagen hair syndrome (LAHS) compared with other forms of childhood alopecia. Design Retrospective survey. Setting Academic pediatric dermatology practice. Patients Three hundred seventy-four patients with alopecia referred from July 1, 1997, to June 31, 2007. Main Outcome Measures Epidemiologic data for all forms of alopecia were ascertained, such as sex, age at onset, age at the time ...

Summary A 5-year-old girl was referred to our clinic because of a 5-month history of diffuse hair loss. Her hair was light brown and dull with evident patches of alopecia. There were no signs of scalp inflammation or scarring. A hair pull test revealed multiple hairs, easily and painlessly extracted. Light microscopic examination and trichogram were consistent with loose anagen hair syndrome. This is an unusual benign hair disorder of childhood that improves spontaneously with aging.

We present three children with short stature, the same facial phenotype, macrocephaly, enlarged cerebral spinal fluid spaces, short neck with redundant skin, severe GH deficiency, mild psychomotor delay with attention deficit/hyperactivity disorder (ADHD), mild dilatation of the pulmonary root in two of them, and a unique combination of ectodermal abnormalities. Their appearance, not completely typical of Noonan syndrome, the behavioral phenotype, GH deficiency, darkly pigmented and hairless ski...

• Background and Design.— The loose anagen hair syndrome is a recently described disorder with enhanced hair loss in which anagen hairs can be painlessly pulled from the scalp. Results.— In three families, we have observed an autosomal dominant form of inheritance. We have confirmed that the extracted bulbs consist only of cortical cells and that the hair shafts have an abnormal shape. Using routine light and electron microscopy, we observed disadhesion between all layers of the follicle and wit...

Abstract A distinctive new hair condition, the loose anagen syndrome, features anagen hairs that are loosely anchored and easily pulled from the scalp. The children studied had sparse hair that did not grow long and that pulled easily from the scalp. The majority of patients were blond girls, aged 2 to 5 years, but both sexes and those with dark hair can be affected. The hair was not fragile, and easily pulled hairs were misshapen anagen hairs without external root sheaths. Histologic examinatio...

Scalp imaging techniques are necessary tools for the trichological practice and for visualization of permeation, penetration and absorption processes into and through the scalp and for the research on drug delivery and toxicology. The present letter reviews different scalp imaging techniques and discusses their utility. Moreover, two different studies on scalp imaging techniques are presented in this letter: (1) scalp imaging with phototrichograms in combination with laser scanning microscopy, a...

Resumen Los metodos de exploracion en tricologia se pueden clasificar en 3 categorias: metodos no invasivos (historia clinica, exploracion general, inspeccion y palpacion del cabello y cuero cabelludo, fotografia, dermoscopia, etc.), metodos semi-invasivos (tricograma) e invasivos (biopsia). En este articulo se repasa de forma practica el abordaje de los motivos de consulta en tricologia en la consulta del dermatologo.

Abstract Hair and scalp evaluation techniques can be classified into 3 categories: noninvasive methods (clinical history, general examination, inspection and palpation of the hair and scalp, photography, dermoscopy, etc.); semi-invasive methods (the trichogram); and invasive methods (biopsy). In this article, we provide a practical guide on how to evaluate hair and scalp conditions in the dermatology office.

Hair loss in children can cause psychological stress to the parent and patient alike. Alopecia can be classified into congenital and acquired. Commonly encountered causes of pediatric alopecia (tinea capitis, alopecia areata, traction alopecia and trichotillomania) are reversible if diagnosed early. Special note should be made of the extent and type of alopecia (scarring or nonscarring), any hair shaft anomalies and signs of inflammation. Diagnostic evaluation includes a bewildering array of age...
