    (Sociedad Médica Santiago, 2007) Concha Rogazy, Marcela Andrea; Vera Kellet, Cristián Andrés; Jara Contreras, Aquiles; Atabales Alarcón, Fernando Marcelo; González Bombardiere, Sergio
    Nephrogenic fibrosing dermopathy is a recent designation to describe cutaneous findings in patients with renal disease who developed scleromyxedema-like skin lesions with thickening and hardening of the skin. These skin, lesions appear mainly after hemodialysis or renal transplantation but their origin is still unknown. We report a 63 years old male on hemodialysis and 56 years old male on peritoneal dialysis; who developed a nephrogenic fibrosing dermopathy that was confirmed by pathology and immunohistochemistry with monoclonal antibodies against CD34.

    Endemic Scrub Typhus-like Illness, Chile
    (Centers for Disease Control an Prevention, 2011) Balcells Marty, María Elvira; Rabagliati Borie, Ricardo Miguel; García Cañete, Patricia Del Carmen; Poggi Mayorga, Helena Loreto; Oddo Benavides, Carlos David; Concha Rogazy, Marcela Andrea; Abarca Villaseca, Katia; Jiang, Ju; Kelly, Daryl J.; Richards, Allen L.; Fuerst, Paul A.
    We report a case of scrub typhus in a 54-year-old man who was bitten by several terrestrial leeches during a trip to Chiloe Island in southern Chile in 2006. A molecular sample, identified as related to Orientia tsutsugamushi based on the sequence of the 16S rRNA gene, was obtained from a biopsy specimen of the eschar on the patient's leg. Serologic analysis showed immunoglobulin G conversion against O. tsutsugamushi whole cell antigen. This case and its associated molecular analyses suggest that an Orientia-like agent is present in the Western Hemisphere that can produce scrub typhus-like illness. The molecular analysis suggests that the infectious agent is closely related, although not identical, to members of the Orientia sp. from Asia.
