Best practice options for hair removal in patients with unwanted facial hair using combination therapy with laser: guidelines drawn up by an expert working group.

Hirsutism is a common disorder affecting between 5 and 15% of the population. One of the most devastating consequences of hirsutism is the presence of unwanted facial hair. Treatment of hirsutism involves a two-pronged approach: treating the underlying cause and reduction of visible hair. Laser hair removal is one of the most effective options for reducing visible hair, however, it may not be wholly effective in all patients and combination therapy may need to be considered. Pharmacological therapy is often used in combination with mechanical hair removal due to the time needed for the drug treatment to demonstrate visible results. Clinical data investigating the use of laser treatment in combination with other treatments has focused on laser with topical eflornithine. The expert working group reviews existing data and provides guidance on the use of eflornithine in combination with laser for resistant hirsutism.

Fotodepilación / Photodepilaton

Los pelos indeseados son un problema frecuente para el cual se han desarrollado diferentes tipos de luz como tratamiento de elección. Desde que en 1996 la Food and Drug Administration (FDA) aprobó el primer láser para depilar, se han hechomuchos avances en la tecnología basada en la luz y los láseres. Los láseres y las fuentes de luz intensa pulsada (IPL) con longitudes de onda en el espectro del rojo o casi el infrarrojo (de 600 a 1.200 nm) son los más utilizados para eliminar el pelo, ya que tienen como diana la melanina de la vaina del pelo, la del epitelio del folículo piloso y la de la matriz. El propósito de esta revisión es describir y comparar los diferentes métodos de fotodepilación disponibles actualmente (AU)

Unwanted hair is a common problem for which different types of light therapy have been developed as the treatment of choice. Since 1996, when the American Food and Drug Administration approved the first laser therapy for depilation, much progress has been made in light-based technology and lasers. Lasers and intense pulsed light sources with red or near infrared wavelengths (600 to 1200 nm) are the most widely used for removing hair as they target the melanin of the hair shaft, hair follicle epithelium, and hair matrix. The aim of this review is to describe and compare the different photodepilation methods currently available (AU)

Neonatal pemphigus vulgaris with extensive mucocutaneous lesions from a mother with oral pemphigus vulgaris.

The clinical phenotype of pemphigus is well explained by the combination of desmoglein (Dsg) 1 and Dsg3 distribution pattern and antiDsg autoantibody profile (Dsg compensation theory). It has been reported that neonatal skin has a similar Dsg distribution pattern to adult mucosal epithelia. We describe a newborn girl with mucocutaneous pemphigus vulgaris (PV) from a mother with mucosal dominant PV. The mother had had painful oral erosions for at least 7 months. Histopathological examination and direct and indirect immunofluorescence studies confirmed the diagnosis of PV and neonatal PV in the mother and daughter, respectively. The mother had a high titre of anti-Dsg3 IgG and a low titre of antiDsg1 IgG, while the neonate had only a high titre of anti-Dsg3 IgG, but no detectable antiDsg1 IgG. AntiDsg3 IgG, which caused the oral dominant phenotype in the mother, induced extensive oral as well as cutaneous lesions in the neonate. Our case provides clinical evidence for the Dsg compensation theory in neonatal PV.

Subacute cutaneous lupus erythematosus associated with cinnarizine and thiethylperazine therapy.

We report the case of a woman who developed subacute cutaneous lupus erythematosus (SCLE) after exposure to the sun while taking cinnarizine and thiethylperazine. The patient recalled that 10 years previously, a similar eruption had appeared after sunbathing, while she was taking only cinnarizine. SCLE development in this patient was probably drug related and there is some evidence that cinnarizine played an important pathogenic role.

Acrocyanosis induced by interferon alpha(2a).

A 56-year-old woman with mycosis fungoides developed acrocyanosis each time treatment with interferon alpha(2a) was started. Acrocyanosis disappeared after discontinuing therapy. Immunological study performed while acrocyanosis was present showed elevated antinuclear antibody (ANA) titers and circulating immune-complex levels. Long-term interferon treatment has been related to autoimmune side effects. Raynaud's phenomenon has been observed in patients undergoing interferon treatment associated with elevated ANA titers, to cryoglobulinemia or to arterial occlusion. Acrocyanosis has never before been described as side effect in patients undergoing this treatment. We believe that our patient's acrocyanosis must be considered a side effect of interferon.

Systemic xanthohistiocytoma: a variant of xanthoma disseminatum?

We present a 66-year-old man who had maculopapular pigmented lesions on the skin of the head, neck and trunk suggesting generalized eruptive histiocytoma (GEH). These lesions had a yellowish centre in a target-like pattern that has not been previously described. The patient suffered from diplopia and had a severe sensorimotor polyneuropathy causing progressive paresis of the limbs. The explorations performed disclosed the presence of specific xanthomatous infiltrates in the skin, lungs, respiratory tract, peripheral nerves and meninges, suggesting xanthoma disseminatum (XD) or juvenile xanthogranuloma. Multiple osteolytic lesions of large bones were also found. The infiltrate was CD68, MAC 387 and factor XIIIa positive and S-100 and CD1 negative. Some cells contained worm-like bodies visible by electron microscopy. Our patient presented clinical and immunohistochemical findings suggestive of GEH, juvenile xanthogranuloma or XD, supporting the idea of a wide spectrum of non-Langerhans cell histiocytosis. These specific target-like xanthomatous lesions seem to be unique for this new variant of XD.
