Artropatía de Jaccoud y fibrosis pulmonar en síndrome CREST / Jaccoud’s arthropathy and pulmonary fibrosis in CREST syndrome

Se describe el caso de una paciente de 48 años de edad con diagnóstico de síndrome CREST incompleto (variante de esclerosis sistémica limitada), en quien se documenta la presencia de artropatía de Jaccoud de las manos y compromiso pulmonar intersticial por fibrosis pulmonar tipo neumonía intersticial usual, con positividad para factor reumatoide y anticuerpos contra el péptido citrulinado.Palabras clave: síndrome CREST, artropatía, enfermedad pulmonar intersticial, fibrosis pulmonar.

We report a case of a 48 years old patient with diagnosis of incomplete CREST syndrome (variant limited systemic sclerosis) in who we documented the presence of Jaccoud’s arthropathy of the hands and pulmonary involvement by pulmonary fibrosis type usual interstitial pneumonia, with positivity for rheumatoid factor and anti-cyclic citrullinated peptide antibody.Key words: CREST syndrome, joint disease, interstitial lung disease, pulmonary fibrosis.

Evidencia radiográfica de la acción de los bifosfonatos en el esqueleto inmaduro / Radiographic evidence of the action of biphosphonate on immature skeleton

Presentamos un paciente con diagnóstico de Osteoporosis Juvenil Idiopática a quien se administró ácido zolendrónico, y una serie de pacientes con diagnóstico de Osteogénesis Imperfecta tratados con pamidronato durante varios años. Se describen las imágenes osteocondensantes que aparecen en los huesos tubulares y la pelvis de estos pacientes a consecuencia de su tratamiento con bisfosfonatos, similares a las líneas de Harris (Growth Arrest Lines) que aparecen eventualmente por diversas causas en el esqueleto inmaduro.

We present one patient with Juvenile Idiopathic Osteoporosis (JIO) who was treated with Zolendronic Acid, and a small series Osteogenesis Imperfecta (OI) patients administered on eyelie Pamidronate proteol. We describe dense lines in radiographs of tubular bones and pelvis of these patients appearing. After bisphosphonates treatment, those images are similar to Harris Lines (Growth Arrest Lines) that appear occasionally by several causes on immature skeletons land through life.

An historical review of systemic lupus erythematosus in Latin America.

In this paper we highlight the role and contributions of Latin American researchers in the study of systemic lupus erythematosus (SLE). The first case of SLE in the world was probably from a mummy from the Huary culture in Peru from about 890 AD, which was extensively studied by macroscopic examination and with light and electronic microscopy, as well as conventional radiography. From the end of the 19th century to the present date there have been many contributions of Latin Americans to the knowledge base of SLE. In this article, we discuss the initial observations of SLE in Latin America and then more specifically review the most important contributions to knowledge about SLE made by physicians in individual Latin American countries, as well as the Gladel group (Latin American group for the study of SLE). The investigation of lupus continues to be pursued by a very dedicated group of Latin American researchers, who continue to enhance our understanding of the pathogenesis and treatment of this condition.
