ABSTRACT
Abstract Background: Childhood is a dynamic period regarding nevogenesis. Dermoscopy is a noninvasive technique, recommended for the evaluation of pigmented cutaneous lesions. Objectives: The purpose of this study was to describe the structures and dermoscopic patterns of melanocytic nevi observed in children and adolescents. Methods: Dermoscopy with photographic documentation was used for nevi located on the face, trunk, and extremities of 38 patients aged from one to 16 years examined at the Pediatric Dermatology Outpatient Clinic of the Federal University of São Paulo. Results: The study included 201 skin lesions that were diagnosed as nevi during clinic examination. Upon evaluation of the global dermoscopic pattern of the lesions, the most frequently observed nevi were reticular (39.0%), followed by homogeneous (23.9%) and globular nevi (16.4%). During evaluation of the dermoscopic structures, according to the body site, the pigment network was the most observed in the extremities. Study limitations: A limitation to be considered is that the inclusion of small or new lesions may hinder the differentiation between dots and globules. Conclusions: In our study, the most observed pattern was reticular. There was a difference in the predominance of structures dependent on the anatomical location.

The aim of this study was to evaluate the sensitivity of interictal compared to ictal SPECT in the lateralization of the epileptogenic focus in refractory temporal lobe epilepsy (TLE) patients that present with normal magnetic resonance imaging (MRI) or bilateral mesial temporal sclerosis (MTS). Thirty patients with TLE, for whom MRI examinations were normal or who presented with bilateral MTS, were retrospectively studied. Using a confidence interval of 95 percent and a level of significance for p-value <0.05, an estimated agreement rate of 73 percent with a minimum agreement rate of 57 percent was calculated comparing interictal and ictal SPECTs. In conclusion the interictal SPECT is only useful when associated with the ictal SPECT and does not substitute it in the localization of epileptogenic areas in patients with normal MRI or bilateral MTS.
O objetivo deste estudo foi avaliar a sensibilidade do SPECT interictal, em relação ao ictal, na lateralização do foco epileptogênico, de pacientes com epilepsia refratária de lobo temporal (ELT) que apresentam ressonância magnética (RM) normal ou esclerose mesial temporal (EMT) bilateral. Foram estudados retrospectivamente 30 pacientes com ELT, nos quais os exames de RM eram normais ou apresentavam EMT bilateral. Avaliada a sensibilidade do SPECT interictal em relação ao ictal, obtivemos taxa estimada de acerto de 73 por cento com taxa mínima de acerto de 57 por cento, adotando intervalo de confiança de 95 por cento e índice de significância p<0,05. Conclui-se que o SPECT interictal é necessário apenas quando associado ao SPECT ictal, e não substitui a realização do ictal na localização da AE em pacientes com RM normal ou EMT bilateral.

Os aneurismas de artérias ilíacas rotos apresentam altas taxas de mortalidade, comparáveis as dos aneurismasde aorta rotos. O tratamento endovascular é considerado atualmente como o de escolha para essas lesões,devido à menor morbimortalidade por ele proporcionado, em comparação à cirurgia aberta. Relata-se o casode um paciente de 80 anos de idade, com comorbidades multissistêmicas, apresentando aneurisma de artériailíaca comum esquerda roto, que foi submetido ao tratamento endoluminal, evoluindo com exclusão doaneurisma e ausência de endovazamentos pós procedimento.
The ruptured aneurysms of iliac arteries have high mortality rates, comparable to those of ruptured aneurysmsof the aorta. Currently the endovascular treatment is considered as the choice for these lesions, due to lowermorbidity when compared with open surgery. We report the case of an 80-year old patient, with multiplecomorbidities, presenting ruptured aneurysm of left common iliac artery, which was submitted to endovasculartreatment, excluding the aneurysm and absence of endoleaks after procedure.
