Prácticas nacionales de analgesia, sedación y delirium en las Unidades de Cuidados Intensivos de adultos en Chile / Analgesia, sedation, neuromuscular blockade and delirium management practices in Chilean intensive care units

Background: The appropriate use of analgesia, sedation, neuromuscular blockade and the diagnosis and prevention of delirium (ASBD) are associated with better outcomes in critically ill patients at Intensive Care Unit (ICUs). Aim: To know the practices about analgesia, sedation, delirium, and neuromuscular blockade use among healthcare professionals working in adult ICUs in Chile. Material and Methods: An electronic survey was sent to 812 professionals working in ICUs using a previously published instrument, which was adapted and authorized by the author. Results: We received 278 surveys. Fifty two percent of respondents were physicians, 34% nurses and 11% physical therapists. Their age ranged between 30 and 39 years in 43% and was over 50 years in 9%. Eighty four percent evaluated pain routinely, but only 26% use a validated scale. Sedation was routinely evaluated with a validated scale and 73% referred to have a protocol. Neuromuscular block is seldom used, and little monitoring occurs (43%). Delirium is routinely evaluated by 48% of respondents, usually using the CAM-ICU scale. Conclusions: There is a heterogeneous adherence to the ASBD recommended practices. The main gaps are in the assessment of pain, monitoring of neuromuscular blockade and diagnosis of delirium through validated instruments.

Tricodisplasia espinulosa asociada a leucemia linfoblástica aguda en edad pediátrica: revisión de la literatura a propósito de un caso / Trichodysplasia spinulosa associated with acute lymphoblastic leukemia in pediatric age: review of the literature regarding a case

La tricodisplasia espinulosa es una patología viral infrecuente causada por un tipo de poliomavirus, el cual se da siempre en contexto de inmunosupresión. Existen reportes que estiman una seroprevalencia en adultos de 70%, y hasta 90% en inmu-nocomprometidos. El cuadro clínico se caracteriza por pápulas color piel hiperqueratósicas en zonas centro faciales, orejas y tronco, asintomáticas o con prurito escaso. Existen métodos de confirmación diagnóstica como PCR o test de Elisa, que no se encuentran disponibles en Chile. Por lo tanto, en nuestro contexto el estudio histopatológico es fun-damental, dada su accesibilidad y que los hallazgos de la biopsia son característicos. El manejo debe siempre considerar, de ser posible, disminuir la in-munosupresión del paciente. Otras medidas son: extracción manual de las lesiones y aplicación de cidofovir o valganciclovir tópicos

Trichodysplasia spinulosa is an infrequent viral pathology caused by a type of polyomavirus, which always occurs in context of immunosuppression. There are reports that estimate sero-prevalence in adults of 70%, and 90% in immunocompromised. Patients have numerous, mildly pruritic, folliculocentric, flesh-colored to pink papules with central keratinaceous spines. There are methods of diagnostic confirmation such as PCR or Elisa test, not available in Chile. The-refore, in our context the histopathological study is fundamental because biopsy findings are cha-racteristic. Management should always consider, if possible, decrease the immunosuppression of the patient. Other measures consist of manual extraction and cidofovir or topical valganciclovir.
