- Use of Smartphones in Telemedicine: Comparative Study Between Standard and Teledermatological Evaluation of High-Complex Care Hospital Inpatients(2016) OKITA, Aline Lissa; TINOCO, Luisa Juliatto Molina; PATATAS, Olivia Helena Gomes; GUERREIRO, Alinie; CRIADO, Paulo Ricardo; GABBI, Tatiana Villas Boas; FERREIRA, Paula Silva; FESTA NETO, CyroBackground: It is estimated that there are around 7 billion mobile phone subscriptions worldwide. Considering the availability and convenience, it appears to be a suitable device for store-and-forward (SF) consultations. Introduction: Although teledermatology has been suggested as an effective way of reducing costs and providing otherwise inaccessible expert evaluation, most studies have relied on high cost and high technological means. Materials and Methods: We conducted a study with inpatients that required dermatological evaluation in a high-complexity university hospital, accessing the correlation between traditional face-to-face evaluation and SF teledermatology, with data and pictures collected by medical students using smartphone cameras and then sent to consultants by e-mail. Results: For 2 months, we evaluated 100 patients and, as a result, the total agreement between both consultation modalities was 54%, the partial agreement was 27%, and the disagreement was 19%. Discussion: This study points out that SF teledermatology with the use of mobile phone is comparable to traditional face-to-face evaluation. Furthermore, most of the disagreements were probably related to the inexperience of the medical residents. Conclusion: Our study suggests that a smartphone-based teledermatology inpatient consultation model could be a reasonable option for hospitals lacking dermatological services. Also, it may be as or more effective than face-to-face consultations, if performed by a more experienced dermatologist. When feasible, photographing training should be performed.
- In vivo confocal microscopy of dermoscopic suspicious lesions in patients with xeroderma pigmentosum: A cross-sectional study(2020) ROCHA, Lilian; FERREIRA, Paula Silva; AVANCINI, Joao; LOURENCO, Silvia; BARBOSA, Caroline de Freitas; COLACIQUE, Caroline; FESTA-NETO, CyroBackground: Xeroderma pigmentosum (XP) is a rare genetic disease characterized by extreme photosensitivity, resulting in a higher incidence of cutaneous tumors. Reflectance confocal microscopy (RCM) is a noninvasive imaging method for diagnosing cutaneous lesions. Objective: To explore the application of RCM in the follow-up of patients with XP. Methods: Patients with XP underwent RCM for suspicious lesions from January 2010 through April 2019. Lesions with malignant RCM features were excised, and the results were compared with their histopathologic features. Benign lesions on RCM were monitored every 3 months. We recorded the confocal features that were related to malignancy and specifically to melanoma. Results: A total of 61 suspicious lesions from 13 patients with XP were included. Thirty-three lesions (54%) were malignant (14 melanomas, 15 basal cell carcinomas, and 4 squamous cell carcinomas). Nonvisible papillae (OR, 11.8; 95% CI, 2.6-53.1; P = .001) and atypical cells at the dermoepidermal junction (OR, 11.7; 95% CI, 2.7-50.3; P = .001) were independent predictors of malignancy. Limitations: There were limited numbers of patients and lesions. Most cases were retrospectively included, and some did not have a histologic analysis. Conclusions: RCM is a valuable tool in the follow-up of patients with XP, reducing the need for excisions by 35%.
