Is trichoscopy a reliable tool to diagnose early female pattern hair loss?

Background: Female pattern hair loss (FPHL) presents with visible patterns of hair loss, thus making a bedside diagnosis possible. However, there are cases of FPHL presenting without any visible hair thinning, making it necessary to subject them to a scalp biopsy to make a diagnosis.

Aim: The aim of the following study is to determine if trichoscopy can be used as a bedside tool to diagnose Early FPHL in women presenting without any visible thinning of hair, using >20% hair diameter diversity - anisotrichosis, as the diagnostic criteria.

Inadvertent Provocative Oral Ondansetron use Leading to Toxic Epidermal Necrolysis in an HIV-infected Patient.

Toxic epidermal necrolysis (TEN) is a severe cutaneous adverse reaction to drugs, characterized by extensive detachment of epidermis and mucous membranes with a mortality of 30-40%. An increased occurrence of cutaneous drug reactions is seen in patients with human immunodeficiency virus (HIV) infection. We present this case of TEN caused by ondansetron in an HIV-infected patient.

Automated Digital Image Analysis (TrichoScan®) for Human Hair Growth Analysis: Ease versus Errors.

Background: TrichoScan(®) is considered to be time-saving, easy to perform and consistent for quantifying hair loss/growth. Conflicting results of our study lead us to closely observe the image analysis, and certain repeated errors in the detection of hair were highlighted.

Aims: To assess the utility of TrichoScan in quantification of diffuse hair loss in males with androgenetic alopecia (AGA) and females with diffuse telogen hair loss, with regard to total hair density (THD), telogen and vellus hair percentages.
