Paederus dermatitis is a peculiar contact dermatitis caused by pederine contained in the hemolimph of a small insect of the genus Paederus. It is characterized by vesico-pustulous eruption arising over an erythematous background, of sudden onset, over exposed areas of the body, and the history of outdoor activities. Diagnosis is based on the typical clinical features and the epidemiological context. The aim of this publication is to report a case and evaluate the epidemiological and clinical characteristics of Paederus dermatitis.

Tinea capitis is a fungal infection caused by dermatophytes, frequent in children but uncommon in the neonatal period. Kerion Celsi is the inflammatory manifestation of tinea capitis secondary to host immunologic responses and its occurrence in newborns is extremely infrequent. We describe three neonates with the diagnosis of kerion Celsi. The isolated dermatophytes were Trichophyton mentagrophytes var. mentagrophytes in two patients and Trichophyton rubrum in the third. Both patients with T. mentagrophytes referred an indirect contact with rabbits and were successfully treated with systemic antifungal (griseofulvin and fluconazole). The patient with T. rubrum had a father with a tinea manuum and both received just topical antimycotic treatment.

Subungual exostosis is a benign bony outgrowth surrounded by a fibrocartilaginous capsule that mainly affects hallux terminal phalanx with subungual or periungular localization, and that clinically determines variable degree of nail plate or periungular soft tissues alterations, respectively, It is uncommon in childhood and more frequent in females. Clinical suspicion is confirmed by the radiographic finding of a distinct trabecular bone growth arising from the dorsal aspect of the phalanx of the affected finger, on the lateral incidence. Curettage or surgical excision is the treatment of choice. We report a case of subungual exostosis located at the hallux in a 14-year-old boy suffering from subungual exostosis of the hallux that presented the characteristic triad of this entity: subungular tumor with nail plate deformity, digital pain and radiologic typical findings.

Introduction: The performance of medical residents can be adversely affected by sleep deprivation, which happens as a consequence of extended work hours., Objective: To assess the effects of sleep deprivation on quick reaction, attention, and memory of pediatrics residents after a duty day. POPULATION, MATERIAL AND METHOD: A before and after, descriptive study was conducted. 44 medical residents, distributed in two groups, were included. The first group (23 residents) was subject to two evaluations, one on a non-duty day and then another on an on-duty day. The second group was evaluated only after a duty day and it was used to assess the learning effect. All participants took: a questionnaire including sleep hours, Epworth sleepiness scale, Maslach burnout inventory, Trail making test, PASAT test, digit span, Signoret memory battery and reaction time test. The degree of deterioration in the tests was assessed after an on-duty day., Results: The average sleep hours on the on-duty day was 3 h. A significant deterioration was evidenced in the visual reaction speed tests. Attention, and memory were not affected after the duty hours., Conclusion: The speed of reaction is deteriorated by the sleep deprivation experienced by medical residents:
