We report the first case of Myroides phaeus isolated from blood, causing bacteremia in an immunocompromised patient using the automated MicroScan Walk Away 96 system, followed by bacterial identification by amplification-sequencing of the 16S rDNA. The sequences obtained were compared with the reference sequence of the BLAST ® platform - National Library of Medicine, USA, and the isolation was identified as Myroides phaeus strain with 99.67 % identity in Blast report. In the literature we did not find previous reported cases of infections by this bacterium, however its pathogenic role is still controversial; therefore, this isolation alerts us to carry out an exhaustive surveillance of other possible acquisition routes.

Introducción: La histoplasmosis es una infección fúngica endémica en Perú, y la co-infección con VIH conlleva dificultades diagnósticas y alta mortalidad asociada. Objetivo: Describir las características clínicas, epidemiológicas y desenlace clínico en pacientes con infección por VIH con diagnóstico de histoplasmosis diseminada (HD) en el Hospital Nacional Guillermo Almenara Irigoyen, Lima-Perú. Material y Métodos: Estudio retrospectivo, descriptivo; se obtuvo información del registro informático de pacientes con infección por VIH con diagnóstico de HD, durante el período 1996-2014. Se describieron características clínicas, epidemiológicas, tratamiento y desenlace. Resultados: Se encontraron 27 pacientes, 25 (92,6%) fueron varones, con edad media de 36,7 años (± 9,4 años) y 22 (81,5%) tuvieron antecedente epidemiológico. Dieciséis (59,3%) tuvieron HD como enfe...

Antimicrobial resistance (AMR) is an additional slow-evolving pandemic that precedes the COVID-19 pandemic and will continue when it ends. However, in countries such as Peru where there is high consumption and inadequate prescription of antibiotics, a more challenging future scenario can be expected. Antimicrobial Stewardship Programs (ASP) are multidisciplinary teams of professionals that aim to contain the emergence of multidrug-resistant organisms through strategies such as audit of antibiotic prescription or creating antibiotic treatment guidelines based on local AMR rates. The difficulty in the timely diagnosis of co-infections or superinfections in the clinical course of COVID-19 leads to inappropriate use of antibiotics, forcing ASP to adapt their strategies in this changing scenario. In Latin America, ASP not only has to promote behavior change in antibiotic prescribers but also ...

One of the efficient techniques that is currently used in pavement engineering to improve the stress–strain response conditions of the pavement structure includes the stabilization of its structural layer components. There are several laying techniques that include the usage of stabilizing agents such as emulsified and foamed asphalt. In these technologies, the temperature of the environment is observed to play a critical role. This condition is often considered to be the main factor that encourages the usage of foamed asphalt for stabilization. Further, the aforementioned technique specifies that, at temperatures of approximately 10 °C or lower, the asphalt particles are not effectively inserted in the foamed granular material mastic; they are instead merged with other asphalt particles. This causes an agglomeration of coalesced asphalt, prevents adequate foaming, and hinders the pav...

Although the relationship between paracoccidioidomycosis (PCM) and solid tumors has been described more than 80 years ago, reports of PCM and gastric cancer are rare. PCM can present before or concomitantly with the diagnosis of cancer, and its clinical presentation may rise the suspicion of malignancies or be part of reactivation by immunosuppression. We present the case of a 52-year-old Peruvian man with a signet-ring cell (SRC) gastric adenocarcinoma who after 6 chemotherapy sessions with FLOT (docetaxel, oxaliplatin, leucovorin, 5-fluorouracil) presented rapidly growing lung nodules. The lung biopsy showed yeasts compatible with Paracoccidioides sp., so he received initial treatment with itraconazole and after gastrectomy maintenance therapy with trimethoprim/sulfamethoxazole accompanied by tomographic resolution of lesions.

In all health care settings, particularly those in developing countries, healthcare workers have a high risk for exposure to tuberculosis. Tuberculosis can involve any organ, including the skin. Cutaneous tuberculosis is uncommon and may be secondary to an exogenous inoculation. We report the case of a surgical resident at a tertiary care hospital in Lima, Peru who developed cutaneous inoculation tuberculosis after sustaining a needlestick injury while performing a diagnostic cervical lymph node aspiration from a patient with HIV infection and tuberculous cervical lymphadenopathy.

Este reporte concluye que se encontró un perfil único de microbiota nasofaríngea en pacientes con COVID-19 con diferente gravedad de la enfermedad. Lactobacillus, Prevotella, Veilonella, Bacteroidetes y Firmicutes fueron los géneros bacterianos predominantes en pacientes críticos y hospitalizados.
