ABSTRACT
PURPOSE: The aim of this study was to design an intraoral environment simulator and to assess the accuracy of two intraoral scanners using the simulator. MATERIALS AND METHODS: A box-shaped intraoral environment simulator was designed to simulate two specific intraoral environments. The cast was scanned 10 times by Identica Blue (MEDIT, Seoul, South Korea), TRIOS (3Shape, Copenhagen, Denmark), and CS3500 (Carestream Dental, Georgia, USA) scanners in the two simulated groups. The distances between the left and right canines (D3), first molars (D6), second molars (D7), and the left canine and left second molar (D37) were measured. The distance data were analyzed by the Kruskal-Wallis test. RESULTS: The differences in intraoral environments were not statistically significant (P>.05). Between intraoral scanners, statistically significant differences (P < .05) were revealed by the Kruskal-Wallis test with regard to D3 and D6. CONCLUSION: No difference due to the intraoral environment was revealed. The simulator will contribute to the higher accuracy of intraoral scanners in the future.

La enfermedad de pie-mano-boca es un exantema frecuente en la niñez. Se han descrito varios tipos de lesiones de distribución generalizada en casos atípicos, aunque los datos sobre la predilección respecto de la localización de estas lesiones son insuficientes. Nuestro objetivo fue describir las características demográficas de los pacientes con esta enfermedad y caracterizar las localizaciones de las lesiones en pacientes con erupciones atípicas, tratadas en un centro ambulatorio de dermatología de un hospital pediátrico, entre noviembre de 2011 y agosto de 2013. Se incluyen a 67 pacientes en el estudio. La edad media de los pacientes fue de 34 meses con predominio de varones (60%). Todos los pacientes tuvieron erupciones en la boca, las manos y los pies. Los niños <24 meses se vieron afectados en la zona cubierta por el pañal y las extremidades, con un compromiso significativamente mayor en los que tenían entre 24 y 48 meses y en los >48 meses (p <0,0001 y p= 0,011, respectivamente). Ninguno de los pacientes tuvo complicaciones sistémicas graves.
Hand-foot-and-mouth disease (HFMD) is a common childhood exanthem. Various types of lesions and widespread distribution in atypical cases have been described, but data on the predilection of lesion localizations in atypical cases are insufficient. We aimed to describe the demographic features of patients with HFMD, and to characterize lesion localizations in patients with atypical eruptions treated at an outpatient dermatology clinic of a pediatric hospital, between November 2011 and August 2013.The study included 67 patients. Mean age of the patients was 34 months and there was a male predominance (60%). All the patients had eruptions on hands, feet, and mouth. Children aged <24 months had involvement of the diaper area and extremities, which was significantly higher than those aged 24-48 months and >48 months (P < 0.0001 and P= 0.011, respectively). None of the patients had serious systemic complications.

Bilateral acute iris transillumination (BAIT) is a relatively new clinical entity characterized by bilateral acute loss of iris pigment epithelium, iris transillumination, pigment dispersion in the anterior chamber, and sphincter paralysis. We report the case of a 30-year-old male who was initially diagnosed with acute iridocyclitis in a different clinic and treated with topical and systemic corticosteroids. He was referred to our clinic to seek another opinion because his symptoms did not improve. An ocular examination revealed bilateral pigment dispersion into the anterior chamber, diffuse iris transillumination, pigment dusting on the anterior lens capsule, atonic and distorted pupils, and increased intraocular pressure, suggesting a diagnosis of BAIT rather than iridocyclitis. Clinicians should be aware of the differential diagnosis of syndromes associated with pigment dispersion from iridocyclitis to avoid aggressive anti-inflammatory therapy and detailed investigation for uveitis.
A transiluminação de íris aguda bilateral (do inglês, bilateral acute iris transillumination, BAIT) é uma entidade clínica relativamente nova, caracterizada pela perda aguda bilateral do epitélio pigmentado da íris, transiluminação iriana, dispersão de pigmentos na câmara anterior, e paralisia do esfíncter pupilar. Nós relatamos o caso de um homem de 30 anos que foi diagnosticado com iridociclite aguda e tratado com corticosteroides tópicos e sistêmicos. Ele foi encaminhado ao nosso serviço para outra opinião, porque seus sintomas não melhoram com a terapia. Um exame oftalmológico revelou dispersão bilateral de pigmentos para a câmara anterior, transiluminação difusa de íris, pigmento difusa na cápsula anterior do cristalino, pupilas atônicas e distorcidas, e um aumento da pressão intraocular, o que sugere um diagnóstico de BAIT em vez de iridociclite. Os médicos devem estar cientes do diagnóstico diferencial das síndromes associadas à dispersão de pigmento com a iridociclite para evitar a terapia antiinflamatória agressiva e investigação detalhada para uveíte.
