ABSTRACT
Abstract The heart and lung are target organs in systemic sclerosis (SSc) and similar symptoms (dyspnea and cough) may make the differential diagnosis between the two lesions difficult. In addition, complete atrioventricular block (CAVB) is a rare complication of this disease. This case report is about a patient with SSc and pulmonary fibrosis who was admitted to the emergency room with CAVB, heart failure (HF) and progressive worsening of the underlying disease.

Abstract Nailfold capillaroscopy (NFC) is a reproducible, simple, low-cost, and safe imaging technique used for morphological analysis of nail bed capillaries. It is considered to be extremely useful for the investigation of Raynaud's phenomenon and for the early diagnosis of systemic sclerosis (SSc). The capillaroscopic pattern typically associated with SSc, scleroderma ("SD") pattern, is characterized by dilated capillaries, microhemorrhages, avascular areas and/or capillary loss, and distortion of the capillary architecture. The aim of these recommendations is to provide orientation regarding the relevance of NFC, and to establish a consensus on the indications, nomenclature, the interpretation of NFC findings and the technical equipments that should be used. These recommendations were formulated based on a systematic literature review of studies included in the database MEDLINE (PubMed) without any time restriction.

Introducción: La dermatoscopía de superficie ha mostrado utilidad en el examen de pacientes con enfermedades de tejido conectivo. Anormalidades de los vasos capilares del repliegue ungueal proximal se pueden presentar en etapas iniciales de dichas enfermedades y su hallazgo puede ayudar al diagnóstico temprano de éstas. Este estudio tuvo como objetivo describir los hallazgos capilaroscópicos del repliegue ungueal proximal en pacientes pediátricos con lupus eritematoso sistémico, dermatomiositis y esclerodermia. Materiales y métodos: Estudio observacional, prospectivo, transversal y descriptivo. Se incluyeron 53 pacientes de entre 2 y 18 años de edad. El repliegue ungueal proximal de todos ellos fue observado con dermatoscopio manual de luz polarizada. Resultados: Todos los pacientes con dermatomiositis y esclerodermia y 14 de 30 pacientes con lupus eritematoso sistémico mostraron hallazgos anormales en el repliegue ungueal proximal. Éstos consistieron en una desorganización de la distribución capilar normal, aumento de los lazos capilares, capilares ramificados, pérdida progresiva de capilares, megacapilares y microhemorragias. Discusión: Los hallazgos capilaroscópicos del repliegue ungueal proximal en pacientes pediátricos con lupus eritematoso sistémico, dermatomiositis y esclerodermia tienen utilidad para el diagnóstico.
Introduction: Superficial dermatoscopy has proved useful in the examination of connective tissue diseases. Anomalies in capillary vessels of the proximal nailfold may be present in early stages of these diseases, and this finding may aid in their early diagnosis. The objective of this study was to determine capillaroscopic findings of the proximal nailfold in pediatric patients with systemic lupus erythematosus, dermatomyositis and sclerodermia. Materials and methods: Observational, prospective, transversal and descriptive study. Fifty-three patients with an age range between 2 and 18 years were included. The proximal nailfold of each patient was observed with a manual polarized light dermatoscopeResults: All of the patients diagnosed with dermatomyositis and sclerodermia, and 14 of 30 patients with systemic lupus erythematosus showed significant signs in the proximal nailfold, which consisted of capillary distribution disorganization, branched capillaries, progressive loss of capillaries, megacapillaries and microhemorrages. Discussion: Capillaroscopic findings of the proximal nailfold in pediatric patients with systemic lupus erythematosus, sclerodermia and dermatomyositis are useful for diagnosis.
