ABSTRACT
We report a case of Enterocytozoon bieneusi infection in a pediatric hematopoietic stem cell transplant recipient in Argentina. Spores were visualized in feces using Calcofluor White and modified trichrome stainings. PCR and sequencing identified E. bieneusi genotype D in fecal samples and liver samples, confirming extraintestinal dissemination of the parasite.

BACKGROUND: The Public Health Services at the Metropolitan Region (MR) of Chile have nine acute psychiatric beds per 100,000 inhabitants, under international recommendations. AIM: The present study will evaluate the resolution capacity of the main MR Psychiatric Emergency Room (PER), which may help assess the impact of the availability of acute beds in the MR. MATERIAL AND METHODS: A retrospective observational study of electronic patient records for all adult patients attending PER of the Psychiatric Institute "Dr. José Horwitz B." between 2017 and 2020 was analyzed. Crude and adjusted Incidence Rate Ratios were obtained for the indication of hospitalization, admissions, and those rejected due to lack of acute psychiatric beds. RESULTS: 90,464 attendances were evaluated on 41,541 patients, and hospitalization was indicated for 12.5% of them. Admissions were carried out in 59.5%, and 35.9% did not occur due to a lack of acute psychiatric beds. When comparing the adjusted Incidence Rates, only a higher hospitalization rate was observed for users from regions (IRR = 1,267; 95% CI: 1,11-1,44; p-value < 0.001) and during the first half of 2020 (IRR = 1.49; CI95%: 1.35-1.65; p-value < 0.001). CONCLUSIONS: The demand for psychiatric hospitalizations and the low availability of acute psychiatric beds in the MR probably have unsuspected consequences. The solution requires multilevel planning among all the actors involved.

INTRODUCCIÓN: Los Servicios de Salud Públicos de la Región Metropolitana (RM) cuentan con 9 camas psiquiátricas de corta estadía por 100.000 habitantes adultos, por debajo de las recomendaciones internacionales. OBJETIVO: El presente estudio evaluará la capacidad de resolución del principal Servicio de Urgencias Psiquiátricas de la RM lo que puede ser de utilidad para evaluar el impacto de la disponibilidad de camas de corta estadía en la RM. MATERIALES Y MÉTODO: Se realizó un estudio observacional retrospectivo de todas las atenciones realizadas en el Servicio de Urgencias del Instituto Psiquiátrico "Dr. José Horwitz B." entre los años 2017 y 2020 y las indicaciones de hospitalización y su resolución. Se obtuvieron Razones de Tasas de Incidencia crudas y ajustadas para la indicación de hospitalización, las efectuadas y aquellas rechazadas por falta de vacantes. RESULTADOS: Se realizaron 90.464 atenciones a 41.541 usuarios y se indicó la hospitalización al 12,5% de ellas. La hospitalización se efectúa en el 59,5% de las atenciones y 35,9% no se pueden realizar por falta de vacantes. Al comparar las Tasas de Incidencia ajustadas se observó solamente una mayor tasa de hospitalización efectuada para los usuarios de regiones (IRR = 1,27; IC95%: 1,11-1,44; valor-p < 0,001) y durante el primer semestre de 2020 (IRR = 1,49; IC95%: 1,35-1,65; valor-p < 0,001). CONCLUSIONES: La evidente demanda por las hospitalizaciones psiquiátricas y la baja disponibilidad de camas de corta estadía en la Región Metropolitana probablemente tiene consecuencias insospechadas. Su abordaje es un desafío que requiere de una planificación multinivel entre todos los actores involucrados.

Abstract Microsporidia are obligate intracellular fungi with a remarkable ability to infect a wide range of invertebrate and vertebrate hosts. Namely, Enterocytozoon bieneusi is the most frequently microsporidia reported worldwide, and mainly associated with chronic diarrea and wasting syndrome in AIDS patients. Microscopy and PCR-based detection techniques are effective for diagnosis and identification of species and genotypes; however, these methods should be standardized in each laboratory. In this study, we performed microscopy and nested PCR techniques with PCR product sequencing to detect E. bieneusi in human stool samples. These techniques, if applied together, might prove useful for diagnosis and future epidemiological studies of intestinal microsporidiosis in Argentina.
Resumen Los microsporidios son hongos intracelulares obligados con una notable capacidad para infectar una amplia gama de hospedadores invertebrados y vertebrados. Enterocytozoon bieneusi es el microsporidio más frecuentemente reportado en todo el mundo, principalmente tricrómicaasociado con diarrea crónica y síndrome debilitante en pacientes con sida. Las técnicas dedetección basadas en microscopía y PCR son útiles para el diagnóstico y la identificación deespecies y genotipos, pero estos métodos deben estar estandarizados en cada laboratorio.En este estudio evaluamos técnicas de microscopía y PCR anidada, con secuenciación de losproductos, para detectar E. bieneusi en muestras de heces humanas. Estas técnicas, usadas con-juntamente, podrían ser útiles para su aplicación en el diagnóstico de microsporidiosis intestinaly para realizar estudios epidemiológicos de esta afección en Argentina.

Background: Cannabis use among young people in Chile has increased significantly in the last years. There is a consistent link between cannabis and psychosis. Aim: To compare cannabis use in patients with a first episode of psychosis and healthy controls. Material and Methods: We included 74 patients aged 20 ± 3 years (78% males) admitted to hospital with a first episode of psychosis and a group of 60 healthy controls aged 23 ± 4 years (63% males). Cannabis consumption was assessed, including age of first time use and length of regular use. Results: Patients with psychosis reported a non-significantly higher frequency of life-time cannabis use. Patients had longer periods of regular cannabis use compared with healthy subjects (Odds ratio [OR] 2.4; 95% confi-dence intervals [CI] 1.14-5.05). Patients also used cannabis for the first time at an earlier age (16 compared with 17 years, p < 0.0). The population attributable fraction for regular cannabis use associated with hospital admissions due to psychosis was 17.7% (95% CI 1.2-45.5%). Conclusions: Cannabis use is related to psychosis in this Chilean group of patients. This relationship is stronger in patients with early exposure to the drug and longer the regular use. One of every five admissions due to psychosis is associated with cannabis consumption. These data should influence cannabis legisla-tion and the public policies currently being discussed in Chile.

The Work Accidents and Occupational Diseases Act exists in Chile since 1968. It uses a single model for the understanding and management of both somatic diseases like silicosis and psychiatric disorders. During the last decade in Chile, the consultation rates due to psychiatric conditions of probable labor origin has rose over 1,000%, a factor that underscored the deficiencies of this model. The aim of this paper is to analyze the consequences of the application of this act in the psychiatric field for almost 50 years after its promulgation. This article contains an historical overview and an epistemological debate based on the authors experience dealing with clinical and administrative work both in occupational psychiatry departments and in regulatory entities. The development of occupational mental health in Chile is examined as part of an historical process that initially did not consider the relationship between work and mental suffering as relevant. The application of a single causality model in psychiatry, as well as the effects of building a psychiatric nosology upon legal rather than medical criteria is contested.

El propósito de este estudio fue evaluar la variación de la morfología superficial, estructura histológica y color del esmalte de las caras vestibulares de piezas dentarias anteriores expuestas a diferentes concentraciones y tiempos de exposición de peróxido de carbamida. El estudio se llevó a cabo en 21 piezas dentarias extraídas que fueron divididas en tres grupos y sometidos a distintas concentraciones de peróxido de carbamida: grupo uno al 5 por ciento; grupo dos al 10 por ciento; y el grupo número tres al 20 por ciento. La cara vestibular de cada diente fue dividida en cuatro cuadrantes, los cuales se expusieron a 5, 20, y 40 horas de blanqueamiento, mientras que un cuadrante fue el grupo control. Los resultados fueron sometidos a la prueba de Friedman para establecer diferencias estadísticas. Se concluyó que morfológicamente, las variaciones en el aspecto superficial fueron mínimas con el gel al 5 por ciento durante las 5, 20 y 40 horas de exposición. Los grupos dos y tres mostraron variaciones significativas ya que su aspecto externo se tornó irregular. Histológicamente, en el grupo uno no hubo cambios significativos en la dirección de los prismas, pero en los grupos dos y tres hubieron cambios en la dirección de los prismas y aumento de las micro porosidades.
