RESUMEN
Trichodynia is the sensation of pain in the scalp, which, in most cases, is associated with certain types of alopecia. Despite being a term coined by Rebora back in 1996 to described patients with diffuse alopecia consistent with telogen effluvium, this symptom has currently been reported in other entities. Androgenic alopecia, scarring alopecia, alopecia areata, trichotillomania, and chemotherapy-induced alopecia are common causes of trichodynia. Similarly, its association with psychiatric comorbidities, including depression, anxiety, obsessive-compulsive disorder and somatoform disorders has been reported with a higher prevalence among women. Although its pathogenesis is still to be elucidate, some factors involved are substance P, psychiatric comorbidities and perifollicular inflammation. Clinically it exhibits pain or discomfort of the scalp, almost always in association with hair los. The sensation of pain can occur throughout the scalp or locally in some specific areas. Diagnosis is clinical and one of exclusion. Regarding treatment, there are no specific therapies for trichodynia. However, the use of botulinum toxin A, antidepressants, neuromodulators, propanolol, topical corticosteroids, oral corticosteroids and topical cannabinoids are therapeutic alternatives that should be taken into consideration. Since treatment of trichodynia is still therapeutically challenging for dermatologists more prospective studies are needed to evaluate new therapies.
RESUMEN
Trichotillomania (TTM) is an obsessive-compulsive disorder in which affected individuals recurrently pull-out hair from any region of the body, causing hair loss or alopecia. The management of TTM is a therapeutic challenge for dermatologists and consists of a combination of pharmacological and non-pharmacological alternatives. Cognitive-behavioral therapy has successfully been used to treat TTM. However, not all patients are willing to follow this treatment strategy. Unconventional support tools are proposed, such as electronic devices, internet therapies and microneedling. N-acetylcysteine and memantine are considered suitable first-line therapies thanks to their favorable safety and efficacy profile, low risk of adverse effects, and significant benefits. The use of other drugs, including fluoxetine, clomipramine, olanzapine, and naltrexone has limited evidence of variable efficacy. The present review illustrates the current treatment modalities for the management of TTM.
RESUMEN
Respiratory tract infection due to Mycoplasma pneumoniae can provoke cutaneous and mucosal rashes, which have been classified within the spectrum of erythema multiforme or Stevens-Johnson syndrome. This classification is of therapeutic and prognostic importance and has generated intense debate in the literature. A recent systematic review of 202 cases of mucocutaneous rashes associated with M. pneumoniae infection concluded that these rashes might constitute a distinct entity, for which the term Mycoplasma-induced rash and mucositis was proposed. We describe a patient with acute M pneumoniae respiratory tract infection who presented mucosal and cutaneous lesions that were difficult to classify as erythema multiforme or Stevens-Johnson syndrome; the lesions were compatible with the proposed new disease.

Pulsed dye and carbon dioxide lasers have been applied in dermatofibroma with clinical improvement. We treated 23 dermatofibromas two times at a 4-week interval with Q-Switched alexandrite laser 755nm (7.5J/cm2, 3mm, 50ms). V Beam pulsed dye laser with a wavelength of 595nm was used for the residual erythema (10-11J/cm2, 7mm, 1.5ms). A partial attenuation of brown colour was observed in 9 patients and complete disappearance of brown colour in 14 patients. Patient satisfaction was very high. Fifteen patients felt a decrease in hardening of dermatofibroma after treatment. A pigment network in dermoscopy was observed in all patients before treatment and no one after treatment. A combined treatment using both V Beam pulsed dye laser and Q-Switched alexandrite laser may be a therapeutic option to reduce the aesthetic effect of dermatofibroma with a high patient satisfaction and good cosmetic outcomes.
