Reporte de caso: Se analizaron cinco casos infrecuentes a nivel estacional en un hospital al norte de Perú durante el periodo de abril a junio del 2019, donde se observaron pacientes con neumonía causados por VSR, confirmado por inmunofluorescencia directa, radiografía de tórax y con presencia de hallazgos clínicos asociados hepatomegalia y atelectasia. De los 05 casos: 4 correspondieron a niños y una niña, en edades comprendidas de 2-7 meses, todos fueron hospitalizados, presentaron sibilancias, crepitantes y politiraje como signos prevalentes al ingreso, todos desarrollaron cuadro de neumonía severa y complicaciones, se registraron dos defunciones en menores de 6 meses, con complicaciones de sepsis, PARDS y ventilación mecánica. Conclusión: los casos presentados reflejan cuadros clínicos característicos de la enfermedad, neumonía y atelectasia en lactantes, complicaciones como SOB, PARDS y hepatomegalia.

Background: The respiratory syncytial virus (RSV) responsible for pneumonia and cause of hospitalization in critical pediatric areas, can cause deaths in infants. Report of case: Five infrequent cases were analyzed at a seasonal level in a hospital in northern Peru during the period from April to June 2019, where patients with pneumonia caused by RSV were observed, confirmed by direct immunofluorescence, chest radiography and with the presence of associated clinical findings hepatomegaly and atelectasis. Of the 05 cases: 4 correspond to boys and a girl, aged 2-7 months, all were hospitalized, presented wheezing, crackles and polytirage as prevalent signs at admission, all developed severe pneumonia and complications, were recorded two deaths in children under 6 months of age, with complications of sepsis, PARDS, and mechanical ventilation. Conclusion: the cases reflect characteristic clinical pictures of the disease, pneumonia and atelectasis in infants, complications such as SOB, PARDS and hepatomegaly.

Seroprevalence of toxoplasmosis in pregnant women and its associated factors among hospital and community populations in Lambayeque, Peru.

INTRODUCTION: Toxoplasmosis is a zoonosis caused by Toxoplasma gondii. This study investigated the prevalence and factors associated with toxoplasmosis among pregnant women. METHODS: We followed an analytical observational study. From July 2016 to June 2017, 218 pregnant women were selected. The infection was detected through serological dosage of anti-T.gondii Immunoglobulin(Ig) M and IgG antibodies. RESULTS: The seroprevalence was 35.8%; the factors associated with infection were consumption of non-drinking water, residence in an urban area, and threatened abortion during the current pregnancy. CONCLUSIONS: The seroprevalence of toxoplasmosis among pregnant women is high. The risk factors are dependent on environmental determinants.

Enteropatógenos predominantes en diarreas agudas y variables asociadas en niños atendidos en el Hospital Regional Lambayeque, Perú / Predominant enteropathogens in acute diarrhea and associated variables in children at the Lambayeque Regional Hospital, Peru

Objetivo: Determinar el tipo y frecuencia de enteropatógenos predominantes en diarreas agudas y sus características asociadas en niños atendidos en el Hospital Regional Lambayeque (HRL) - Perú. Materiales y métodos: Se realizó un estudio analítico transversal entre marzo y mayo del 2015 en 70 muestras fecales. Las muestras se estudiaron mediante coprocultivo e inmunocromatografía para la detección de bacterias y virus enteropatógenos respectivamente. Mientras que los enteroparásitos se buscaron mediante examen microscópico directo, tinción de Kinyoun y ELISA para coproantígenos (Entamoeba histolytica, Giardia lamblia y Cryptosporidium spp.). Asimismo se realizó conteo de leucocitos y pruebas químicas (Benedict, Thevenon y Sudan III) para el estudio funcional de la enfermedad diarreica. Resultados: En el 48,6% de muestras se detectó la etiología infecciosa de la diarrea, siendo predominante la causa parasitaria (25,8%), seguida de la bacteriana (17,1%) y viral (5,8%). Los enteropatógenos más frecuentes fueron G. lamblia (18,6%) y Salmonella Enteritidis (10,0%). Se observó asociación entre la cantidad de leucocitos mayor a 100 con la etiología bacteriana (p=0,027), mientras que un número menor de 10 por campo (p=0,002) y el Sudan III positivo (p=0,003) con la etiología parasitaria. Conclusiones: En más de la mitad de muestras (51,4%) no se demostró etiología infecciosa de la diarrea, mientras que Giardia lamblia fue la más frecuente causa de diarrea en la población estudiada. No obstante, es necesaria la implementación de técnicas más sensibles y específicas para la detección de un rango mayor de enteropatógenos con el que se mejore el diagnóstico y tratamiento de la enfermedad

Objective: To determine the type and frequency of predominant enteropathogens in acute diarrhea and their associated characteristics in children treated at Hospital Regional Lambayeque (HRL) - Peru. Materials and methods: A cross-sectional analytical study was carried out in 70 fecal samples between March and May 2015. These samples were studied by coproculture and immunochromatography for the detection of enteropathogenic bacteria and viruses, respectively, while enteroparasites were sought by direct microscopic examination, Kinyoun staining method and ELISA for the detection of coproantigens (Entamoeba histolytica, Giardia lamblia and Cryptosporidium spp). Leukocyte count and chemical tests (Benedict, Thevenon and Sudan III) were also performed for the functional study of the diarrheal disease. Results: In 48.6% of the samples, the infectious etiology of diarrhea was detected, prevailing the parasitic cause (25.8%), followed by the bacterial (17.1%) and viral (5.8%) ones. The most common enteropathogens were G. lamblia (18.6%) and Salmonella enteritidis (10.0%). An association between greater than 100 fecal leukocytes per field and the bacterial etiology (p=0.027) was observed, while less than 10 fecal leukocytes per field (p=0.002) and a positive Sudam III test (p=0.003) were associated with the parasitic etiology. Conclusions: In more than half of the samples (51.4%) the infectious etiology of diarrhea could not be proven, whereas Giardia lamblia was the most frequent cause of diarrhea in the studied population. However, it is necessary to implement more sensitive and specific techniques for the detection of a greater range of enteropathogens with which to improve the diagnosis and treatment of the disease

[Leptospirosis frequency and socio-demographic characteristics associated in febrile patients from northern Perú]. / Frecuencia de leptospirosis y características socio-demográficas en pacientes febriles del norte del Perú.

UNLABELLED: INDRODUCTION: Leptospirosis is a frequent cause of febrile illness around the world, particularly in tropical and subtropical areas such as Perú. OBJECTIVE: To estimate the frequency and socio-demographic characteristics associated with leptospirosis in febrile patients in northern Perú. MATERIALS AND METHODS: A cross sectional study was conducted from January to December 2014 in 143 fever cases admitted to the Hospital Regional Lambayeque, Perú. Structured for socio-demographic information and sanitation questionnaire was used. Serum samples were examined to quantitatively determine the presence of IgM antibodies to leptospira using ELISA IgM. RESULTS: The frequency was 26.6% (95% CI 19.3 to 33.8) and independently associated features were: be between 20-54 years (OR: 3.36, 95% CI 1.17 to 9, 64), work in agriculture-livestock (OR: 6.15, 95% CI 1.99 to 19.05),contact with animals (OR: 4,13, IC 95%: 1,76-9,65) and consumption of unsafe water(OR: 3,33, IC 95%: 1,49-7,43). CONCLUSIONS: This study reveals a high frequency of leptospirosis among febrile patients from northern Perú. These results indicate the need to investigate routinely leptospirosis in febrile patients, especially those exhibiting risk characteristics.
