Callus due to dermatophagia has rarely been reported in dermatology literature. Patients with this disorder usually present with skin damage, bleeding, blistering and discoloration, especially around the fingernails. Moreover, the presence of callus on the dorsum of proximal phalanges has also rarely described in the literature of PubMed, Google Scholar and Research Gate. We hereby describe a 16-year-old boy with bilateral calluses, on the dorsal aspects of the proximal phalanges of the forefingers. General physical examination revealed that the patient had a mental illness and a habit of biting his fingers at the affected sites for two years. We performed this report to emphasize the importance of the relationship between dermatophagia and calluses presenting on the dorsum of the proximal phalanges of the fingers as calluses are most often located on the feet and knuckles of the hands. Therefore, any patient experiencing a similar lesion to the one in our case needs a proper history taken and assessment of mental state to exclude associated psychiatric comorbidity.

“…No presente estudo, analisamos principalmente as DP decorrentes de desordens psiquiátricas primárias com manifestações psicológicas, como ansiedade, depressão, estresse emocional ou transtornos obsessivoscompulsivos [1]. Essas dermatoses são prevalentes em mais de um terço dos participantes do estudo, assim como têm sido encontradas em ambulatórios de dermatologia [11][12][13]. No estudo apresentado, a dermatose mais frequente foi a escoriação de acne ou picada de inseto (37,99%), condizente com outros estudos que sugerem ser a manifestação psicocutânea mais comum [14].…”

“…Outra dermatose identificada com alta frequência foi retirada da cutícula, mordida em lábios e bochechas (32,40%), sendo esta e a onicofagia (14,30%) compreendidas dentro do transtorno de comportamento repetitivo focado no corpo, o qual, por sua vez, é ligado ao transtorno obsessivo-compulsivo, provocando grande estresse psicológico, exacerbando a ansiedade e relacionando-se à baixa autoestima [2,13]. O prurido psicogênico apresentou-se com frequência de 14,63%.…”

ObjetivoEste artigo almejou comparar a frequência de dermatoses psicossomáticas e a qualidade de vida de estudantes universitários da área de saúde.MétodosNeste estudo analítico, transversal e quantitativo, foram aplicados dois questionários on-line para estudantes da saúde: World Health Organization Quality of Life Scale Abbreviated Version, para avaliar a qualidade de vida, e outro elaborado pelos pesquisadores para analisar a frequência de oito psicodermatoses e sua relação com o estresse, o desconforto com as lesões e a busca pela ajuda médica ou psicológica. Para aferir a relação entreas dermatoses psicossomáticas e a qualidade de vida, foi considerado p<0,05 do teste qui-quadrado.Resultados Participaram do estudo 608 estudantes. A dermatose mais frequente foi escoriação (37,99%), seguida de retirada de cutícula, mordida em lábios e bochechas (32,40%) e prurido psicogênico (14,63%), sendo a automutilação a com menor frequência (1,15%). Dos que tiveram alguma dermatose psicossomática, 82,33% acreditam que estão relacionadas ao estresse acadêmico, 66,20% se sentem desconfortáveis, e 43,45% já buscaram ajuda médica ou psicológica. A qualidade de vida foi considerada boa por 92,76% no domínio físico, 95,72% no meio ambiente, 88,81% no psicológico e 88,89% nas relações sociais. Houve associação entre a queda da qualidade de vida no domínio físico e a frequência das dermatoses psicossomáticas retirada de cutícula, mordida em lábios ou bochechas (p=0,001), tricotilomania (p=0,055) e prurido psicogênico (p=0,0009); e, no psicológico, com retirada de cutícula, mordida de lábios ou bochechas (p=0,059), escoriações (p=0,087) e prurido psicogênico (p=0,002).Conclusão Dermatoses psicossomáticas são encontradas em mais de 30% dos estudantes; porém, sua associação com a queda de qualidade de vida não pode ser confirmada.

Stress has been demonstrated to play an important role in hair follicle function and the pathogenesis of some hair disorders. The central hypothalamic-pituitary-adrenal (HPA) axis is activated by stress stimuli, synthesizes and releases various components and eventually induces the pathogenesis and recurrence of peripheral diseases. Our aim is to compare the different responses under exposure of stress in hair follicle function among different mouse strains, and to detect the involvement of the central HPA axis after stress in hair follicle growth and melanogenesis. In this study, we exposed different mouse strains (C57BL/6, CBA/J, C3H/HeN, BALB/c and ICR) to a 21-day chronic restraint stress protocol and selected C57BL/6, CBA/J and BALB/c mice for further study because of their significant behavioral alterations. Then, we evaluated and compared the different responses and sensitivity to chronic restraint stress in hair follicle function and central HPA axis among the selected strains. The results showed that expression of POMC, CRF and GR mRNA and protein and serum levels of corticosterone were inhibited in response to stress. These findings suggested that chronic restraint stress may inhibit hair follicle growth and melanogenesis via regulating the key elements of the central HPA axis. In addition, the results revealed different mouse strains exhibit different responses in the central HPA axis and hair follicle after stress exposure. C57BL/6 might be the most sensitive strain among the three strains tested as well as an appropriate strain to study possible pathophysiological mechanisms by which the nervous system influences skin function and screen dermatological drugs suitable for psychotherapy. We believe the current study will provide some useful information for researchers who are interested in the bidirectional communication between the nervous and skin systems and the management of stress-induced cutaneous diseases.
