RESUMO
Differently from immunocompromised patients, very little information is available in the literature regarding the clinical presentation, epidemiology, and outcomes of histoplasmosis in non-immunosuppressed individuals living in endemic areas. This retrospective case series study was carried out by reviewing the medical records of non-immunocompromised patients with histoplasmosis, residents in a hyperendemic area in northeastern Brazil, between 2011 and 2022. Thirty HIV-negative patients were identified with histoplasmosis, and 19 cases met the inclusion criteria: three had acute, five subacute and one chronic pulmonary forms; two with mediastinal picture and eight had disseminated disease (two with severe symptoms). The median age of our sample was 32.7 years old [interquartile range: 24-45]. Most of the patients were male (male-to-female ratio = 15:4) and resided in the state capital (n = 9). The majority had a previous history of exposure to well-known risk factors for Histoplasma infection. Pulmonary nodules were observed in all subacute form, two patients (acute and subacute forms) were initially treated empirically for pulmonary tuberculosis; one death was registered in the subacute form. The chronic pulmonary form of histoplasmosis was diagnosed in one patient only after the symptoms persisted despite specific treatment. The primary clinical manifestations of the moderate form of DH were enlarged lymph nodes, with histopathology being the main diagnostic method. The cases were detected as isolated occurrences and not as an outbreak, suggesting that exposure to Histoplasma can be more widespread than presumed. Despite the self-limiting nature of the disease, death can occur even in previously heathy patients.
This study aimed to describe the presentation of histoplasmosis outside the context of immunosuppression, including the diagnostic methods, epidemiology, and main radiological and clinical features. A better understanding of the various forms of this disease will help improve case management.

Music-based interventions (MBI) in therapeutic routine have been observed as an effective tool for adjuvant therapy for patients with chronic diseases and for those with various types of disabilities. Music can serve as a pedagogical and therapeutic strategy for development of psychomotor skills in children and adolescents with long-lasting illnesses, and also as a secular way of promoting comfort and spiritual health for patients and families during difficult times; it can also be used to alleviate suffering during diagnostic and therapeutic procedures throughout the long recovery and/or rehabilitation processes. In this article, a musician and art therapist describes some simple MBI used daily in a tertiary children's hospital in Sao Paulo, where patients with chronic diseases and from lower socioeconomic background represent most of outpatients and inpatients. Some MBI developed or adapted by the author are described in detail, some of them using only the voice and others utilizing simple musical instruments, usually percussion ones, by the patients themselves. There are also reports describing MBI in special situations, such as long-lasting isolation of immunosuppressed patients (for bone marrow transplantation, for example), regular day-hospital visits for hemodialysis and religious songs for families of end-of-life or critically ill patients. In conclusion, MBI can be beneficial for improving patient experience in hospital settings, particularly for those with long-lasting or repeated stays, and can be performed in a simple and playful way, with contribution of other health professionals with some background in music, since music therapy specialists are still scarce in many countries.
RESUMO
We describe the very prolonged course of the disease in an immunosuppressed patient with persistently positive PCR against SARS-CoV-2 with low cycle threshold for at least 114 days.

La bacteriemia representa una importante causa de morbimortalidad en pacientes oncológicos. Durante el episodio de neutropenia inducida por quimioterapia, un 15%25% de los pacientes tendrá bacteriemia. Objetivo: identificar factores de riesgo asociados con bacteriemia en pacientes oncológicos pediátricos con neutropenia y fiebre. Material y métodos: estudio de cohorte prospectivo. Se incluyeron pacientes con enfermedades hematooncológicas y neutropenia febril, internados en un hospital pediátrico de alta complejidad entre julio de 2018 y mayo de 2019. Se excluyeron receptores de trasplante de médula ósea. Se compararon las características clínicas según se documentara bacteriemia (B) o no. Resultados: Se incluyeron 160 pacientes (p). Eran varones 93 (58%). La mediana de edad fue 81,5 meses (RIC 36-127,5). La enfermedad de base (EB) más frecuente fue: leucemia linfoblástica aguda (LLA) 88 (55%). Se identificaron 20 (12,5%) pacientes con bacteriemia (B). En el análisis univariado hubo asociación entre B y LMA (p=0,003) y la internación en UCI (p=0,0001). En el modelo multivariado, ajustado por el resto de las variables, se identificaron la LMA (OR 8,24, IC95% 2,5-26,4; p<0,001) y la tiflitis (OR 5,86, IC95% 1,2-27,3; p=0,02) como factores relacionados con bacteriemia. Los principales microorganismos identificados fueron: estreptococos del grupo viridans 6 (30%), Escherichia coli 4 (20%) y estafilococos coagulasa negativos 3 (15%). Quince (75%) fueron bacteriemias secundarias a un foco clínico. El foco más frecuente fue el mucocutáneo (n=7, 35%). En esta cohorte de niños con cáncer y neutropenia febril, los factores asociados con bacteriemia fueron: la LMA, la tiflitis y la internación en UCI (AU)
Bacteremia is an important cause of morbidity and mortality in oncology patients. During an episode of chemotherapy-induced neutropenia, 15%-25% of patients will develop bacteremia. Objective: to identify risk factors associated with bacteremia in pediatric oncology patients with neutropenia and fever. Material and methods: prospective cohort study. Patients with hematology-oncology diseases and febrile neutropenia, admitted to a tertiary-care pediatric hospital between July 2018 and May 2019 were included. Bone marrow transplant recipients were excluded. Clinical characteristics were compared according to whether or not bacteremia was recorded. Results: 160 patients were included of whom 93 (58%) were male. Median age was 81.5 months (IQR 36-127.5). The most common underlying disease was acute lymphoblastic leukemia (ALL) in 88 patients (55%). Twenty (12.5%) patients with bacteremia were identified. In univariate analysis, an association was found between bacteremia and acute myeloid leukemia (AML) (p=0.003) and ICU admission (p=0.0001). In the multivariate model, adjusted for the remaining variables, AML (OR 8.24; 95%CI 2.5-26.4; p<0.001) and typhlitis (OR 5.86; 95%CI 1.2-27.3; p=0.02) were identified as factors related to bacteremia. The main microorganisms identified were viridans group streptococci in 6 (30%), Escherichia coli in 4 (20%), and coagulase negative staphylococci in 3 (15%). In 15 cases (75%), bacteremia was secondary to a clinical focus. The most frequent focus was mucocutaneous (n=7, 35%). In this cohort of children with cancer and febrile neutropenia, the factors associated with bacteremia were AML, typhlitis, and ICU admission (AU)

Por las particularidades de los hospitales, su entorno contiene un gran número de microorganismos proporcionando condiciones muy favorables para la reproducción y la propagación de microorganismos patógenos. Por otro lado, como un sitio importante del uso de antibióticos, las infecciones asociadas a hospitales y la resistencia a los antimicrobianos promueven mutuamente la formación de un círculo vicioso. Existen fuertes evidencias de que la transmisión por aire y aerosoles de los microorganismos patógenos están muy extendidos en los entornos hospitalarios. En ese sentido, las partículas transportadas por el aire se caracterizan por su baja densidad, invisibilidad y susceptibilidad a la turbulencia. El asentamiento de partículas infecciosas en el aire sobre la herida de un paciente puede causar infecciones en cirugía o en caso más graves, infectar a pacientes con sistemas inmunológicos comprometidos, o puede conducir, si las condiciones de ventilación no son apropiadas, a la diseminación de bacterias y hongos (bioaerosoles) desde pacientes infecciosos a toda la comunidad hospitalaria. Para mejorar el estado de estas infecciones asociadas a los hospitales, los sistemas tradicionales se han centrado en estrategias para eliminar patógenos presentes en pacientes, superficies clínicas y trabajadores de la salud, que ha impulsado la implementación de varios protocolos de control y desinfección de infecciones que también han tenido éxito en la reducción de la incidencia de este tipo de infecciones hospitalarias. Dentro de estos procedimientos, está el uso de sistema de ventilación con presión de aire positiva o negativa El objetivo de este trabajo es determinar la capacidad de control microbiano de los sistemas de ventilación en dos centros de asistencia médica del Perú en habitaciones con pacientes inmunosuprimidos (VIH/Sida) aislados o en habitaciones de pacientes infecciosos(AU)
Due to the particularities of hospitals, their environment contains a large number of microorganisms, providing very favorable conditions for the reproduction and spread of pathogenic microorganisms. On the other hand, as an important site of antibiotic use, hospital-associated infections and antimicrobial resistance mutually promote the formation of a vicious circle. There is strong evidence that airborne and aerosol transmission of pathogenic microorganisms is widespread in hospital settings. In that sense, airborne particles are characterized by their low density, invisibility, and susceptibility to turbulence. The settling of airborne infectious particles on a patient's wound can cause infections in surgery or, in more serious cases, infect patients with compromised immune systems, or can lead, if ventilation conditions are not appropriate, to the spread of pathogens. bacteria and fungi (bioaerosols) from infectious patients to the entire hospital community. To improve the status of these hospital-associated infections, traditional systems have focused on strategies to eliminate pathogens present in patients, clinical surfaces, and healthcare workers, which has prompted the implementation of various infection control and disinfection protocols that they have also been successful in reducing the incidence of this type of hospital infection. Within these procedures, there is the use of a ventilation system with positive or negative air pressure. The objective of this work is to determine the microbial control capacity of the ventilation systems in two medical care centers in Peru in rooms with immunosuppressed patients (HIV/AIDS) isolated or in infectious patient rooms(AU)

RESUMO
El Ectima gangrenoso es un trastorno infeccioso infrecuente, clásicamente relacionado a bacteriemia, descrito principalmente en poblaciones inmunodeprimidas. Se asocia con la sepsis y bacteriemia por P. aeruginosa en pacientes inmunodeprimidos, incluidos aquellos con neutropenia o inmunodeï¬ciencias, también se han descrito casos por hongos ï¬lamentosos y levaduras. Se ha observado en aproximadamente un 1,3-3 % de los casos de bacteriemia por P. Aeruginosa1. Se ha descrito ectima en pacientes con déï¬cit en su inmunidad2, como en el caso que se describe a continuación. El Ectima puede presentarse como lesión única o múltiple, caracterizadas por máculas eritematosas que progresan a vesículas, bullas o pústula, evolucionando hasta la necrosis central con halo eritematoso. Se presenta el caso de un paciente con Ectima Gangrenoso, refractario inicialmente a tratamiento, que evolucionó con empeoramiento progresivo, presentándose en el hemograma hiperleucocitosis asociado a anemia y trombopenia, con diagnóstico ulterior de Leucemia Mieloide Aguda.
Ecthyma gangrenosum is an uncommon infectious disorder classically associated with bacteremia and found mainly in immunocompromised populations. It is associated with sepsis and Pseudomonas aeruginosa bacteremia in immunocompromised patients, including those with neutropenia or immune deï¬ciencies. There have also been cases caused by ï¬lamentous fungi and yeasts. It has been seen in approximately 1.3 3% of Pseudomonas aeruginosa bacteremias. Ecthyma has been reported in immune-deï¬cient patients, as in the case described below. Ecthyma can present with a single or multiple lesions with erythematous macules progressing to vesicles, bullas or pustules, which develop central necrosis with an erythematous halo. We present the case of a patient, later diagnosed with Acute Myeloid Leukemia, with ecthyma gangrenosum, initially refractory to treatment, which worsened progressively, presenting hyperleukocytosis associated with anemia and thrombocytopenia in the whole blood count.
RESUMO
Resumen: Los adenovirus humanos continúan siendo un desafío en la práctica clínica, se trata de virus de tipo ADN, con amplia distribución en la población, causa frecuente de enfermedad autolimitada en niños. Sin embargo, en pacientes inmunosuprimidos, principalmente trasplantados de células hematopoyéticas y de órganos sólidos, puede llegar a ser causa de enfermedad diseminada severa, con elevada morbimortalidad. Compartimos el primer reporte nacional de enfermedad por adenovirus diseminado, en el que se presentan dos casos clínicos de pacientes trasplantados hepáticos, que desarrollan enfermedad diseminada grave por adenovirus. Se realiza una revisión de la literatura sobre el tema.
Abstract: Human adenoviruses still constitute a challenge in the clinical practice. These are DNA viruses that are widely disseminated among the population and often cause self-limiting diseases in children. However, it may result in a severe diseminated disease with high morbi-mortality rates in immunocompromised patients, in particular transplant recipients of hematopoietic cells and solid organs. The study shares the first national report for disseminated adenovirus disease, presenting two clinical cases of hepatic transplant recipients who developed severe disseminated adenovirus disease. And conducting a literature review on the topic.

BACKGROUND: The current literature is scarce as to the outcomes of COVID-19 infection in non-Hodgkin's lymphoma patients and whether immunosuppressive or chemotherapeutic agents can cause worsening of the patients' condition during COVID-19 infection. CASE PRESENTATION: Our case is a 59-year-old gentleman who presented to the Emergency Department of the Cancer Institute of Hospital das Clínicas da Universidade de São Paulo, São Paulo, Brazil on 10th May 2020 with a worsening dyspnea and chest pain which had started 3 days prior to presentation to the Emergency Department. He had a past history of non-Hodgkin's lymphoma for which he was receiving chemotherapy. Subsequent PCR testing demonstrated that our patient was SARS-CoV-2 positive. CONCLUSION: In this report, we show a patient with non-Hodgkin lymphoma in the middle of chemotherapy, presented a mild clinical course of COVID-19 infection.

Pasteurella multocida is a gram-negative bacterium that colonizes domestic animals. It is commonly implicated in bite and scratch wounds, potentially resulting in cellulitis, superficial abscesses, osteomyelitis, or peritonitis. Rarely, it can lead to bacteremia and septic shock in high-risk patients. We present an atypical presentation of Pasteurella multocida bacteremia and sepsis in a patient with stage 4 decompensated cirrhosis. The patient presented with melena and altered mental status with CT imaging showing a heterogeneous nodular liver along with an enlarged portal vein, gastric varices, and ascites consistent with decompensated cirrhosis. The patient was initially managed with intravenous (IV) octreotide and pantoprazole, blood and platelet transfusions, and broad-spectrum antibiotics. Upper endoscopy showed diffuse non-bleeding esophageal and gastric varices, which required band ligation and continued IV octreotide therapy. The infection resolved after a 7-day course of IV ceftriaxone.
