ABSTRACT
Introducción: la piomiositis (PMS) es una infección bacteriana aguda o subaguda del músculo esquelético. Entidad rara en pediatría, suele acompañarse de la formación de abscesos. Se presenta más frecuentemente en preescolares de sexo masculino, afectando mayoritariamente a extremidades y región pélvica. La manifestación multifocal es frecuente. El principal agente etiológico es Staphylococcus aureus. Caso clínico: 3 años, sexo masculino, sano. Consulta por fiebre continua de hasta 39 ºC de seis días de evolución, dolor de ambos miembros inferiores a predominio izquierdo, cojera y repercusión general. Examen físico: tumoración en muslo izquierdo de límites difusos de 13 x 5 cm, lisa, firme, impresiona adherida a planos musculares, dolorosa. Sin elementos fluxivos en la piel. Ecografía de partes blandas: aumento de tejidos blandos de la extremidad. Resonancia magnética (RM): abscesos que comprometen logia de los aductores del miembro izquierdo, el vasto externo del muslo derecho, musculatura paravertebral lumbar izquierda y cérvico-torácica izquierda. Tratamiento: drenaje, requiere de múltiples limpiezas quirúrgicas y antibioticoterapia prolongada. Cultivo de la lesión: Staphylococcus aureus meticilino resistente (SAMR). Buena evolución clínica e imagenológica. Discusión: la PMS ha presentado una incidencia creciente con la aparición del SAMR. La ecografía es un método adecuado para realizar diagnóstico local. La experiencia en la interpretación de la RM permite pesquisar el compromiso multifocal, identificando focos sin traducción clínica. La antibioticoterapia y el drenaje quirúrgico son los pilares del tratamiento. El pronóstico es bueno en la mayoría de los casos.
Introduction: pyomyositis (PMS) is an acute or subacute bacterial infection of the skeletal muscle. It is a rare infection in pediatrics, and it is usually accompanied by abscess formation. It occurs more frequently in male preschoolers, mostly affecting the extremities and pelvic region. The multifocal manifestation is frequent. The main etiological agent is Staphylococcus aureus. Clinical case: 3 year-old, male, healthy patient. He consulted for continuous fever of up to 39ºC of 6 days of evolution, pain in both lower limbs predominantly on the left, lameness and general repercussions. Physical examination: a 13 x 5 cm tumor in the left thigh with diffuse limits, smooth, firm, adhered to muscle layers, painful. Without fluxive elements on the skin. Soft tissue ultrasound: enlargement of the soft tissues of the extremity. Magnetic resonance imaging (MRI): abscesses involving the adductor lodge of the left limb, the vastus lateralis of the right thigh, left lumbar paravertebral musculature and left cervical-thoracic musculature. Treatment: drainage, requires multiple surgical cleanings and prolonged antibiotic therapy. Culture of the lesion: methicillin-resistant Staphylococcus Aureus (MRSA). Good clinical and imaging evolution. Discussion: PMS has had an increasing incidence with the appearance of MRSA. Ultrasound is a suitable method for local diagnosis. Experience in the interpretation of MRI has enabled us to research multifocal involvement, identifying unobserved foci during clinical check-up. Antibiotic therapy and surgical drainage are the main treatments. The prognosis is good in most cases.
Introdução: Ia Piomiosite (TPM) é uma infecção bacteriana aguda ou subaguda do músculo esquelético. É uma entidade rara em pediatria, costuma vir acompanhada de formação de abscessos. Ocorre com maior frequência em pré-escolares do sexo masculino, afetando principalmente as extremidades e a região pélvica. A manifestação multifocal é comum. O principal agente etiológico é o Staphylococcus aureus. Caso clínico: paciente 3 anos, sexo masculino, hígido. Consulta por febre contínua de até 39ºC há 6 dias, dor em ambos os membros inferiores predominantemente esquerdo, claudicação e repercussão geral. Exame físico: tumor na coxa esquerda com limites difusos de 13 x 5 cm, liso, firme, aparentemente aderido aos planos musculares, doloroso. Sem elementos fluidos na pele. Ultrassonografia de tecidos moles: aumento dos tecidos moles da extremidade. Ressonância magnética (RM): abscessos envolvendo o alojamento adutor do membro esquerdo, vasto lateral da coxa direita, músculos paravertebrais lombares esquerdos e cérvico-torácicos esquerdos. Tratamento: drenagem, requer múltiplas limpezas cirúrgicas e antibioticoterapia prolongada. Cultura da lesão: Staphylococcus aureus resistente à meticilina (MRSA). Boa evolução clínica e imagiológica. Discussão: a TPM tem tido uma incidência crescente com o aparecimento do MRSA. A ultrassonografia é um método adequado para diagnóstico local.

INTRODUCCIÓN: Las bacteriemias por Enterobacterales productores de carbapenemasa KPC (EPC-KPC) presentan una mortalidad elevada y opciones terapéuticas limitadas. OBJETIVOS: Describir y comparar la evolución de los pacientes con bacteriemia por EPC-KPC tratados con ceftazidima/avibactam (CA) frente a otros antimicrobianos (OA). PACIENTES Y MÉTODOS: Estudio prospectivo y retrospectivo de casos y controles. Se incluyeron pacientes adultos con bacteriemia por EPC-KPC, con una proporción entre casos tratados con CA y controles tratados con OA. de 1:2. Se analizaron variables clínicas, epidemiológicas y de evolución. RESULTADOS: Se incluyeron 48 pacientes (16 CA y 32 OA). Los casos se encontraban más frecuentemente neutropénicos (50 vs.16%, p = 0,012); asimismo, presentaron medianas de score de APACHE II más altas y de score de Pitt más bajas. El 65% de la cohorte total presentó un foco clínico y Klebsiellapneumoniae fue el microorganismo más frecuentemente aislado. Los casos recibieron una mayor proporción de tratamiento antimicrobiano empírico adecuado (81 vs. 53%, p = 0,05). La antibioterapia dirigida en casos y controles fue combinada en 38 y 91%, p = 0,009. Los casos presentaron menor mortalidad al día 7 y al día 30 relacionada a infección (0 vs. 22%, p = 0,04 y 0 vs. 34%, p = 0,008). Solo los controles desarrollaron shock, ingresaron a la unidad de cuidados intensivos y presentaron bacteriemia de brecha. CONCLUSIÓN: CA mostró beneficio clínico frente a OA para el tratamiento de pacientes con bacteriemia por EPC-KPC.
BACKGROUND: KPC-producing Enterobacterales bacteremia (KPCCPE) is associated with a high mortality rate and limited therapeutic options. AIM: To describe and compare the outcome of patients with KPC-CPE bacteremia treated with ceftazidime/avibactam (CA) versus other antibiotics (OA). METHODS: Prospective and retrospective cases and control study performed in adult patients with KPC-CPE bacteremia, with a 1:2 ratio between cases treated with CA. and controls treated with OA. Clinical, epidemiological, and outcome variables were analyzed. RESULTS: Forty-eight patients (16 CA and 32 OA) were included. Cases were more frequently neutropenic (50 vs. 16%, p = 0.012), presented higher median APACHE II score and lower Pitt score. Of the total cohort, 65% had a clinical source, and Klebsiella pneumoniae was the most frequently isolated microorganism. Cases received more adequate empirical antibiotic treatment (81 vs. 53%, p = 0.05). Targeted antibiotic therapy in cases and controls was combined in 38 and 91%, p = 0.009. Cases had a lower 7-day mortality and 30-day infection-related mortality (0 vs. 22%, p = 0.04 and 0 vs. 34%, p = 0.008). Only controls developed shock, were admitted to the intensive care unit, and had breakthrough bacteremia. CONCLUSION: CA. showed clinical benefit over OA in the treatment of patients with EPC-KPC bacteremia.

INTRODUCCIÓN: El uso de tigeciclina ha ido en aumento en los últimos años, debido al incremento de la resistencia bacteriana y la escasez de alternativas terapéuticas. OBJETIVO: Caracterizar y evaluar las prescripciones de tigeciclina en pacientes internados en un hospital universitario, durante los años 2017 y 2018. METODOLOGÍA: Estudio observacional retrospectivo, donde se caracterizaron los pacientes, las terapias, la microbiología asociada, los desenlaces clínicos y las reacciones adversas asociadas a los tratamientos con tigeciclina. Se determinó la proporción de prescripciones apropiadas por un comité de expertos y el consumo de tigeciclina medido en DDD/100 camas-día. RESULTADOS: Se caracterizaron 89 pacientes, de los cuales 67 (75,3%) cumplieron los criterios de selección. El 53,7% de los pacientes eran hombres, con una edad promedio de 60 ± 15 años. El principal motivo de hospitalización fue quirúrgico (65,7%). El 67,1% de los tratamientos con tigeciclina se inició en una Unidad de Paciente Critico y el foco de infección predominante fue abdominal (64,3%). El 50% de las terapias con tigeciclina fueron dirigidas según la microbiología identificada. En 65,7% de los casos se usó tigeciclina como monoterapia en la dosis habitual (62,9%). Náuseas (8,6%), diarrea (7,1%) y vómitos (4,3%) fueron los efectos adversos más reportados. El 84,3% de los tratamientos se consideraron apropiados. El año 2017 se consumió 0,4 DDD/100 camas-día y 0,6 DDD/100 camas/día el 2018, siendo la UCI el servicio que presentó el mayor uso en ambos años. DISCUSIÓN: Tigeciclina fue utilizada principalmente en monoterapia para el tratamiento de infecciones intraabdominales en pacientes hospitalizados, por motivos quirúrgicos, en una unidad de paciente crítico, en las dosis habituales recomendadas de 100 mg como dosis de carga seguida de 50 mg cada 12 hs IV. En 50% de los casos, la terapia fue dirigida según microbiología. Los eventos adversos más habituales fueron los gastrointestinales. CONCLUSIÓN: La mayoría de las terapias prescritas fueron consideradas apropiadas por el comité de expertos.
BACKGROUND: The use of tigecycline has been increasing in recent years, due to increase in bacterial resistance and the scarcity of therapeutics alternatives. AIM: To characterize and evaluate the tigecycline prescriptions of patients hospitalized in a university hospital, during the years 2017 and 2018. METHODS: A retrospective observational study was carried out, where the patients, the therapies, the associated microbiology, the clinical outcomes and the adverse reactions associated with tigecycline were characterized. The proportion of appropriate prescriptions was determined by committee of experts and the consumption of tigecycline measure in DDD/100 bed-days. RESULTS: 89 patients who used tigecycline were characterized, of which 67 (75.3%) met the selection criteria. 53.7% of the patients were male, with a mean age of 60 +/- 15 years The main reason for hospitalization was surgical (65.7%). 67.1% of the treatments with tigecycline were started in a critical patient unit and the predominant focus of the infection was the abdomen (64.3%). 50% of the therapies with tigecycline were ordered according to the identified microbiology. In 65.7% of the cases, tigecyclin was used as monotherapy at the usual dose (62.9%). Nausea (8.6%), diarrhea (7.1%) and vomiting (4.3%) were the most reported adverse events. 84.3% of the treatments were considered appropriate. In 2017, 0.4 DDD/100 bed/days were consumed and 0.6 DDD/100 bed/days in 2018, with de ICU being the service that presented the highest use in both years. DISCUSSION: Tigecycline was mainly used as monotherapy for the treatment of intra-abdominal infections in patients hospitalized for surgical reasons in a critical patient unit at the usual doses of 100 mg loading followed by 50 mg every 12 hours IV. In 50% of the case the therapy was directed according to microbiology. The most common adverse events were gastrointestinal. CONCLUSION: Most of the prescribed therapies were considered appropriate by the expert committee.

RESUMEN: El aumento de la resistencia y la escasez de nuevos antibacterianos ha requerido la reintroducción de antiguos antimicrobianos entre ellos colistín. OBJETIVO: Caracterizar la utilización de colistín durante el año 2017 en un hospital universitario, mediante la descripción de los pacientes, los tratamientos, la microbiología asociada y efectos adversos. PACIENTES Y MÉTODOS: Trabajo observacional retrospectivo. Se revisaron los datos de todos los pacientes que recibieron colistín intravenoso (IV) por al menos 48 horas, durante el año 2017. RESULTADOS: Se incluyeron 53 pacientes, equivalentes a 91 tratamientos. El foco respiratorio fue el principal (46,2%). El 68,1% de los tratamientos fue iniciado en la UCI. La mayoría de los pacientes tenía una hospitalización reciente (83,5%), y presentaban uso previo de antibacterianos (89%). Los dos patógenos mayoritariamente identificados fueron Pseudomonas aeruginosa y Klebsiella spp. El consumo promedio de colistín fue de 2,4 DDD/100 camas/día. El servicio que más consumió colistín fue la UCI, con 45,5 DDD/100 camas/día, usando generalmente la dosis de 3 MUI cada 8 horas IV y con una baja utilización de dosis de carga. CONCLUSIÓN: Colistín corresponde a un antimicrobiano de uso restringido a infecciones sospechadas o confirmadas por agentes bacterianos multi resistentes. En esta serie, su uso inicial fue principalmente empírico, en pacientes con factores de riesgo para resistencia antibacteriana; se usó en forma asociada a otros antimicrobianos, siendo el foco principal el respiratorio.
BACKGROUND: The increase in resistance and the shortage of new antibiotics has led to the reintroduction of old antimicrobials such as colistin. AIM: To evaluate the use of colistin during 2017 in a university hospital, through the characterization of patients and treatment, associated microbiology, response to treatment and adverse effects. METHODS: Retrospective observational design. The data of all patients who received colistin for at least 48 hours during the year 2017 were reviewed. RESULTS: 55 patients were included, equivalent to 144 treatments. The respiratory focus was the main one (57.9%). 64% of the treatments began in the ICU, while 7% in the ward. Most of the patients has a recent hospitalization (86.8%) and has previous use of antibiotics (90.4%). The two main pathogens identified were Pseudomonas aeruginosa and Klebsiella spp. In 87.1% of the cases with microbiological justifications for the use of colistin, a favorable response was obtained. The average consumption of colistin was 2.4 DDD/100 beds/day. The department that consumed the most colistin was the ICU, with 45,5 DDD/100 beds/day, generally using a dose of 3 MIU every 8 hours IV and with low use of loading doses. CONCLUSION: Colistin corresponds to an antibiotic whose use is restricted to infections suspected or confirmed by multi-resistant bacterial agents. Its initial use in this serie was mainly empirical, in patients with risk factors for antibiotics resistance, it was used in association with other antimicrobials, being the respiratory the main infectious focus.

Introduction: Intracanal medication with antibiotics is used to ensure the success of treatments. However, no studies evaluating the efficacy of triantibiotic paste after several hours of preparation have been reported. Objective: To evaluate the antimicrobial activity of the triantibiotic paste against Enterococcus faecalis, according to the time of application and storage of the components used for its preparation. Methods: An experimental in vitro study was carried out in the microbiology laboratory of Universidad Nacional Mayor de San Marcos. The sample consisted of three colonies of Enterococcus faecalis, formed in bile-esculin agar. On three specific days (0, 14 and 28), the antimicrobial activity of the conventional (ciprofloxacin/metronidazole/minocycline) and modified (cefaclor/metronidazole/minocycline) paste was evaluated, measuring (mm) the inhibition zones. The freshly obtained components were used to prepare the paste on day 0, and the stored components (powdered antibiotics kept in amber glass bottles at room temperature) were used on days 14 and 28. Two interventions were performed on each specific day (morning and afternoon). Freshly prepared pastes were used in the morning (immediate application), while pastes stored for 6 hours (delayed application) were used in the afternoon. Results: On day 0, it was found that the modified triantibiotic paste of immediate application had higher antimicrobial activity than the one of delayed application (p = 0.046). On day 28, the conventional triantibiotic paste for immediate application showed higher antimicrobial activity than that for delayed application (p = 0.049). Pasta prepared with fresh components (day 0) had higher antimicrobial activity than pasta prepared with components stored for 14 and 28 days. Conclusions: The application time of the triantibiotic paste and the storage times of the components could influence the antimicrobial activity for the eradication of Enterococcus faecalis(AU)
Introducción: La medicación intracanal con antibióticos se utiliza para asegurar el éxito de los tratamientos. Sin embargo, no se han reportado estudios que evalúen la eficacia de la pasta triantibiótica después de varias horas de preparación. Objetivo: Evaluar la actividad antimicrobiana de la pasta triantibiótica frente al Enterococcus faecalis, según el tiempo de aplicación y de almacenamiento de los componentes utilizados para su preparación. Métodos: Estudio experimental in vitro, realizado en el laboratorio de microbiología de la Universidad Nacional Mayor de San Marcos. La muestra consistió en tres colonias de Enterococcus faecalis, formadas en agar bilis-esculina. En tres días específicos (0, 14 y 28) se evaluó la actividad antimicrobiana de la pasta convencional (ciprofloxacina/metronidazol/minociclina) y modificada (cefaclor/metronidazol/minociclina), midiendo las zonas de inhibición (mm). Los componentes recién obtenidos se utilizaron para preparar la pasta el día 0, y los componentes almacenados (antibióticos pulverizados conservados en frascos de vidrio color ámbar a temperatura ambiente) se utilizaron los días 14 y 28. Se realizaron dos intervenciones en cada día específico (mañana y tarde). Las pastas recién preparadas se utilizaron por la mañana (aplicación inmediata), mientras que por la tarde se utilizaron las pastas almacenadas durante 6 horas (aplicación tardía). Resultados: El día 0, se encontró que la pasta triantibiótica modificada de aplicación inmediata presentó una actividad antimicrobiana superior a la de aplicación tardía (p = 0,046). El día 28, la pasta triantibiótica convencional de aplicación inmediata presentó una actividad antimicrobiana superior a la de aplicación tardía (p = 0,049). La pasta preparada con componentes recién obtenidos (día 0) tuvo una mayor actividad antimicrobiana que la pasta preparada con componentes almacenados durante 14 y 28 días. Conclusiones: El tiempo de aplicación de la pasta triantibiótica y los tiempos de almacenamiento de los componentes podrían influir en la actividad antimicrobiana para la erradicación de Enterococcus faecalis(AU)

INTRODUCCIÓN: El método recomendado para la medición de consumo de antimicrobianos (AMB) en pediatría es el cálculo del indicador Días de Terapia estandarizado por ocupación (DOT-std). Sin embargo, en hospitales que no cuentan con fichas electrónicas, obtener el numerador de los días de terapia (DOT) requiere revisión directa de las indicaciones del paciente, dificultando su aplicabilidad. OBJETIVOS: Validar el sistema de registros electrónicos de dispensación de medicamentos desde farmacia como fuente para el cálculo de DOT y DOT-std en la Unidad de Cuidados Intensivos Pediátrica (UCIP). MATERIALES Y MÉTODOS: Se revisaron las prescripciones de AMB desde la ficha clínica (método manual) y se compararon con los registros de dispensación de AMB a la UCIP (método informático) obtenidos del sistema de medicamentos de farmacia. Se evaluó la concordancia entre los DOT obtenidos mediante el Coeficiente de Correlación Intraclase. RESULTADOS: Los AMB más utilizados fueron vancomicina, meropenem y piperacilina/tazobactam. En 9 de 12 AMB se encontró concordancia significativa entre ambos métodos. CONCLUSIONES: Tras un proceso de validación local, los registros del sistema informático de dispensación de medicamentos desde farmacia podrían utilizarse para el cálculo de DOT en pediatría en hospitales que no cuenten con una ficha electrónica que permita su cálculo directo.
BACKGROUND: The recommended indicator for measuring antimicrobial (AMB) consumption in pediatric patients is the Days of Therapy indicator (DOT), which is then standardized by hospital occupancy rates (DOT-std). However, in hospitals that do not have electronic health records, obtaining the DOT requires a direct review of each pharmacological indication, which is not feasible in the long term. AIMS: To validate electronic records from the pharmacy dispensation system as a source for calculating DOT and estimating DOT-std in a Pediatric Intensive Care Unit (PICU). METHODS: AMB prescriptions at the PICU of a university hospital were directly reviewed (manual method) and compared with AMB dispensation records (computer method) obtained from the hospital pharmacy system. The Intraclass Correlation Coefficient was used to evaluate the agreement between the DOT obtained by both methods. RESULTS: The most used AMB were vancomycin, meropenem, and piperacillin/tazobactam. A significant agreement between the DOT obtained by using manual and computer methods was found in 9 of 12 evaluated AMB. CONCLUSIONS: After a local validation process, the electronic records of the pharmacy drug dispensation system could be considered a valid source for calculating DOT in PICUs in hospitals where electronic health records with prescription data are not yet available.

Los antimicrobianos parenterales son esenciales en el tratamiento de infecciones intrahospitalarias, sin embargo, es importante considerar la carga de sodio y volumen que pueden aportar, especialmente, en pacientes con restricción sódica. En el presente estudio se identificaron los antimicrobianos parenterales usados en uno de los hospitales más grandes del Perú. Se revisó la cantidad de sodio intrínseco y se calculó la cantidad de sodio total por día de tratamiento según el régimen frecuentemente usado en adultos. Como resultado, se encontró que 22% de las terapias antimicrobianas superaban el requerimiento de sodio diario, lo que podría ser perjudicial para pacientes con insuficiencia cardiaca, enfermedad renal crónica, con cirrosis hepática, entre otros.
Parenteral antibiotics are essential in the treatment of nosocomial infections; however, their sodium load and volume should be considered as an extra source, especially, in patients with sodium restriction. In this study, we identified the parental antibiotics used in one of the largest hospitals in Peru. We reviewed the amount of intrinsic sodium and we calculated the sodium load per day of treatment according to the commonly used regimen in adults. As a result, we found that 22% of the antibiotic treatment regimens exceed the daily sodium requirement, which could be harmful for patients with heart failure, chronic kidney disease, liver cirrhosis, among others.

Introducción: Las infecciones representan la etiología más frecuente del síndrome febril prolongado (SFP). Si bien las fiebres entéricas constituyen una causa posible, en Uruguay su prevalencia ha disminuido significativamente con la mejora de las condiciones socio sanitarias. Objetivo: Comunicar el caso de un adolescente con una etiología actualmente excepcional de SFP. Caso clínico 14 años, sano, zona suburbana. Comienza 2 semanas previo al ingreso con dolor en hemiabdomen superior. Agrega cefalea holocraneana leve y vómitos ocasionales. 5 días previos al ingreso fiebre 40°C axilar, un pico diario, sin otra sintomatología. Tránsito digestivo bajo y urinario normal. Examen físico: lúcido, buen aspecto general, abdomen doloroso a la palpación profunda en epigastrio. Sin irritación peritoneal. Resto normal. Analítica: Leucocitos 5200mm3, Proteína C reactiva 71.4mg/dL, hemocultivo sin desarrollo. Ecografía abdominal, radiografía de tórax y ecocardiograma normales. Serologías para Virus Epstein Barr, Citomegalovirus, y Bartonella henselae negativas. Orina normal, urocultivo sin desarrollo. Persiste con fiebre, agrega exantema macropapular evanescente en tronco, sin otros síntomas. Al 7° día de internación nuevo hemocultivo: Salmonella Typhi sensible a ampicilina que recibe por 14 días. Buena evolución. Discusión: La fiebre tifoidea es una enfermedad infectocontagiosa, aguda, potencialmente mortal. Las condiciones socioeconómicas son determinantes en su transmisión. La sensibilidad del hemocultivo es mayor durante la primera semana de enfermedad, por lo que en ocasiones es necesario reiterarlo. Sus manifestaciones clínicas inespecíficas y la baja incidencia hacen que esta etiología no sea habitualmente sospechada en nuestro medio. Por tanto, es importante aumentar el índice de sospecha y considerar entre los diagnósticos diferenciales de SFP esta etiología.
Introduction: Infections are the most frequent etiology of prolonged febrile illness (PFI). Although enteric fevers are a possible cause, their prevalence has significantly diminished in Uruguay, due to improved socio-sanitary conditions. Objective: To communicate the case of an adolescent with a currently exceptional etiology of PFI. Clinical case: 14 years old, healthy, suburban area. Two days prior to admission the patient has pain in upper hemi abdomen. Adds mild holocranial headache and occasional vomiting. 5 days prior to admission axilary temperature of 40°C, one daily peak, without other symptoms. Normal lower digestive and urinary transit. Physical examination: lucid, good general aspect, pain at deep palpation in epigastrium. No peritoneal irritation. Rest is normal. Laboratory: leukocytes 5200 mm3, C-reactive protein 71.4mg/dL, blood culture shows no growth. Abdominal sonogram, thoracic X-ray and echocardiogram are normal. Negative serology for Epstein Barr Virus, Cytomegalovirus and Bartonella henselae. Normal urine, urine culture with no growth. Fever persists, adds evanescent macropapular exanthema in on the trunk, without other symptoms. On the 7th day in hospital a new blood culture shows Salmonella Typhi sensitive to ampicillin, which he receives for 14 days. Good evolution. Discussion: Typhoid fever is an acute, life-threatening, infectious disease. Socioeconomic conditions are determinant in its transmission. Blood culture sensitivity is greater during the first week of the disease, that is why it must occasionally be repeated. Its unspecific clinical manifestations and low incidence make this etiology not be usually suspected in our surroundings. It is therefore important to increase our suspicion and to consider it amongst differential diagnosis in PFI.
Introdução: As infecções representam a etiologia mais frequente da síndrome febril prolongada (SFP). Embora as febres entéricas sejam uma causa possível, no Uruguai sua prevalência diminuiu significativamente com a melhoria das condições sociossanitárias. Objetivo: Relatar o caso de um adolescente com etiologia atualmente excepcional de SFP. Caso clínico 14 anos, saudável, zona suburbana. Começa 2 semanas antes da admissão com dor no abdome superior. Adiciona dor de cabeça holocraniana leve e vômitos ocasionais. 5 dias antes da admissão febre 40°C axilar, pico diário, sem outros sintomas. Trânsito digestivo inferior e trânsito urinário normais. Exame físico: lúcido, bom aspecto geral, abdome doloroso à palpação profunda no epigástrio. Sem irritação peritoneal. Resto normal. Análise: Leucócitos 5200mm3, proteína C reativa 71,4mg/dL, hemocultura sem desenvolvimento. Ultrassonografia abdominal, radiografia de tórax e ecocardiograma foram normais. As sorologias para vírus Epstein Barr, Citomegalovírus e Bartonella henselae foram negativas. Urina normal, urocultura sem desenvolvimento. Persiste com febre, acrescenta erupção macropapular evanescente no tronco, sem outros sintomas. No 7º dia de internação, nova hemocultura: Salmonella Typhi sensível à ampicilina, que recebeu por 14 dias. Boa evolução. Discussão: A febre tifóide é uma doença infecciosa aguda, potencialmente fatal. As condições socioeconômicas são decisivas na sua transmissão. A sensibilidade da hemocultura é maior durante a primeira semana da doença, por isso às vezes é necessário repeti-la. Suas manifestações clínicas inespecíficas e baixa incidência fazem com que essa etiologia não seja usualmente suspeitada em nosso meio. Portanto, é importante aumentar o índice de suspeição e considerar essa etiologia entre os diagnósticos diferenciais da SFP.

El parto prematuro (PP) es la principal causa de morbilidad/mortalidad perinatal y frecuentemente es espontáneo, con membranas intactas (MI). La infección intrauterina es su causa más común en un hospital público de Chile. Existe evidencia que la infección bacteriana ascendente desde la vagina es responsable de la infección/inflamación intraamniótica, del PP y de los resultados adversos maternos y perinatales. Esta revisión narrativa incluye ensayos controlados aleatorizados (ECAs), publicados en PubMed, Cochrane, Embase, Scielo, Science Direct, Wiley Online Library, sobre los mecanismos que intervienen en el ascenso de la infección vaginal, los factores infecciosos que participan en el resultado adverso materno-perinatal y la eficacia de los antimicrobianos en estos casos. Estos trabajos no recomiendan usar antimicrobianos profilácticos porque producen daño a corto y largo plazo en los hijos. Pero este resultado tiene sesgo porque no se evaluó la presencia de infección/inflamación subclínica, lo que disminuye el grado de recomendación. También existen ECAs, que erradican la infección/inflamación intraamniótica, reducen la morbilidad/mortalidad neonatal, pero son trabajos aislados, obtenidos de subanálisis, con bajo nivel de evidencia. Se requieren revisiones sistemáticas y metaanális de ECAs con estudio de infección/inflamación subclínica para evaluar si son útiles los antimicrobianos en el PP espontáneo con MI.
Preterm labor (PL) is the leading cause of perinatal morbidity/ mortality and is frequently spontaneous with intact membranes (IM). Intrauterine infection is its most common cause in a public hospital in Chile. There is evidence that ascending bacterial infection from the vagina is responsible for intraamniotic infection/inflammation, PL, and adverse maternal and perinatal outcomes. This narrative review includes randomized controlled trials (RCTs), published in PubMed, Cochrane, Embase, Scielo, Science Direct, Wiley Online Library on the mechanisms involved in the rise of vaginal infection, the infectious factors involved in adverse maternal-perinatal outcomes, and the efficacy of antibiotics in these cases. They do not recommend the use of prophylactic antibiotics because they cause short and long-term damage to children. But this result is biased because the presence of subclinical infection/inflammation was not evaluated, which lowers the degree of recommendation. There are also RCTs that eradicate intra-amniotic infection/inflammation, reduce neonatal morbidity/ mortality, but they are isolated studies, obtained from subanalyses, with a low level of evidence. Systematic reviews and meta-analyses of RCTs with subclinical infection/inflammation study are required to assess whether antibiotics are useful in spontaneous PL with IM.

Introducción: se describe a nivel mundial un aumento en la prescripción de macrólidos en niños y adolescentes, generando el riesgo de emergencia de cepas resistentes. Objetivo: caracterizar el uso de macrólidos en niños de 1 mes a 14 años hospitalizados en cuidados moderados e intensivos del Hospital Pediátrico del Centro Hospitalario Pereira Rossell (HP-CHPR). Metodología: estudio descriptivo transversal de niños hospitalizados tratados con macrólidos en el HP-CHPR en 2018. Variables: tipo de macrólido, duración del tratamiento, estudios y hallazgos microbiológicos y diagnóstico al egreso. Resultados: recibieron macrólidos 334 niños, mediana de edad 13 meses, 58,4% varones. 71,0% en Unidad de Terapia Intensiva (UTI). Predominó la prescripción de claritromicina (72,8%), durante los dos últimos cuatrimestres del año (77,5%) y por patología respiratoria (94%): bronquiolitis (23,3%), infección aguda no especificada de las vías respiratorias inferiores (21,9%) y crisis asmática (19,1%). Mediana de tratamiento con azitromicina y claritromicina 5 y 8 días respectivamente. Se realizaron estudios microbiológicos en 96,1% sin determinarse microorganismo en 58,3%. Conclusiones: se destaca el uso de macrólidos principalmente en la UTI y por patología respiratoria. La prescripción por fuera de las recomendaciones nacionales vigentes y la baja confirmación microbiológica que apoye el uso fueron los mayores problemas detectados, por lo que parece fundamental establecer estrategias tendientes a promover un uso racional de estos antibióticos.
Introduction: literature has described a global increase in the prescription of macrolides to children and adolescents , which has increased the risk of emergence of resistant strains. Objective: to characterize the use of macrolides in children from 1 month to 14 years of age hospitalized at the moderate and intensive care units of the Pereira Rossell Pediatric Hospital Center (HP-CHPR). Methodology: descriptive cross-sectional study of hospitalized children treated with macrolides at the HP-CHPR in 2018. Variables: macrolide type, treatment duration, microbiological studies and findings, and diagnosis at discharge. Results: 334 children received macrolides, median age 13 months, 58.4% males. 71.0% hospitalized atnan Intensive Care Unit (ICU). Clarithromycin was mainly prescribed in 72.8% of the cases, during the last two quarters of the year (77.5%), due to respiratory disease (94%): bronchiolitis (23.3%), lower respiratory tract unspecified acute infection (21.9%) and asthma crisis (19.1%). Median treatment included Azithromycin and Clarithromycin for 5 and 8 days respectively. Microbiological studies were carried out in 96.1% of the cases and 58.3% did not show the presence of microorganisms. Conclusions: the use of macrolides stands out, mainly at ICUs and due to respiratory pathologies. The main problems identified were prescriptions made outside the framework of the present national recommendations and the low microbiological confirmation for their use, which suggests it is essential to set strategies to promote a more rational use of these antibiotics.
Introdução: a literatura descreve um aumento a nível global na prescrição de macrolídeos para crianças e adolescentes, o que tem aumentado o risco de surgimento de cepas resistentes. Objetivo: caracterizar o uso de macrolídeos em crianças de 1 mês a 14 anos de idade internadas nas unidades de terapia moderada e intensiva do Centro Hospitalar Pediátrico Pereira Rossell (HP-CHPR). Metodologia: estudo transversal descritivo de crianças hospitalizadas tratadas com macrolídeos no HP-CHPR em 2018. Variáveis: tipo de macrolídeo, duração do tratamento, estudos e achados microbiológicos e diagnóstico no momento da alta. Resultados: 334 crianças receberam macrolídeos, idade mediana de 13 meses, 58,4% do sexo masculino. 71,0% internados em Unidade de Terapia Intensiva (UTI). A Claritromicina foi prescrita principalmente em 72,8% dos casos, nos últimos dois trimestres do ano (77,5%), devido a doença respiratória (94%): bronquiolite (23,3%), infecção aguda não especificada do trato respiratório inferior (21,9%) e crise de asma (19,1%). O tratamento médio incluiu Azitromicina e Claritromicina por 5 e 8 dias, respectivamente. Estudos microbiológicos foram realizados em 96,1% dos casos e 58,3% não evidenciaram a presença de microrganismos. Conclusões: destaca-se o uso de macrolídeos, principalmente em UTIs, e devido a patologias respiratórias. Os principais problemas identificados foram as prescrições feitas fora das atuais recomendações nacionais e a baixa confirmação microbiológica para sua utilização, o que sugere que é essencial definir estratégias para promover uma utilização mais racional destes antibióticos.

Introducción: el impacto de la resistencia antimicrobiana (RAM) generará un aumento de las muertes relacionadas de 10 millones anuales hacia 2050. El 70% de la dispensación de antimicrobianos (ATB) se utiliza en la agroveterinaria y no en salud humana. Es fundamental conocer la portación de RAM en trabajadores de cría de animales y en los animales, para acciones tempranas de salud pública. Métodos: bajo metodología PRISMA se realizó la búsqueda bibliográfica en distintas fuentes disponibles hasta octubre de 2020. Se priorizaron revisiones sistemáticas, metanálisis, ensayos clínicos y estudios observacionales para determinar la RAM en trabajadores de cría de cerdos. De 990 artículos identificados se incluyeron 8 estudios. Resultados: la tasa de colonización por Staphylococcus aureus resistente a la meticilina (SAMR) en trabajadores fue mayor que la de la población general. La prevalencia de SAMR fue significativamente mayor en trabajadores en contacto directo con animales y los de granjas de cría intensiva con respecto a los de extensiva. En cerdos, la prevalencia de RAM en cría intensiva fue significativamente mayor que la de los de cría extensiva. También fue significativa la asociación entre el suministro de antibióticos en la cría intensiva y la presencia de RAM. Las granjas de más de 1250 cerdos presentaron mayor prevalencia de RAM (p < 0,001). El fenotipo de SAMR en cerdos, trabajadores y el ambiente fue el mismo. Conclusiones: existe evidencia de asociación entre la producción agrícola de cría intensiva y la RAM en cerdos y trabajadores. No se encontraron estudios de vigilancia epidemiológica en la Argentina en trabajadores de cría de animales. (AU)
Introduction: it is estimated that the impact of antimicrobial resistance (AMR) will generate an increase of 10 million deaths by 2050, being reflected to a greater extent in low-income countries. 70% of the annual use of antimicrobials is concentrated in agroveterinary but not in human health. Considering the presence of AMR in ranchers and agricultural workers is essential for early public health actions. Methods: using the PRISMA methodology, bibliography was searched in different sources until October 2020. Systematic reviews, meta-analyses, clinical trials and observational studies were prioritized to determine AMR in pig workers. Eight studies of the 990 found have been included. Results: the rate of colonization by methicillin-resistant Staphylococcus aureus (MRSA) in farming workers was higher than the general population. MRSA prevalence was significantly higher in workers who reported direct contact with animals. And also in those workers of intensive farms compared to those of extensive farms. The same situation is observed in swines, in which the prevalence of AMR in intensive farming was significantly higher than in extensive farming. The association between the supply of antibiotics in intensive farming workers and the presence of AMR was also significant. Farms with more than 1,250 swines had a higher prevalence of AMR (p<0.001). The MRSA phenotype found in swine, agricultural workers, and the environment was the same. Conclusions: there is scientific evidence of an association between agricultural production in intensive livestock farming and AMR in swine and farming workers. There aren't Argentine studies of epidemiological surveillance in farming workers. (AU)

Objetivo: Evaluar las complicaciones posoperatorias y la evolución clínica en pacientes sometidos a colectomías y anastomosis con dos estrategias preoperatorias, preparación mecánica (PMC) y preparación mecánica con antibióticos orales (PMC+AO). Materiales y Método: Estudio retrospectivo, con un total de 216 pacientes, 149 fueron del grupo PMC y 67 del PMC+AO. Variables estudiadas: características demográficas, intervención quirúrgica, localización anastomótica, fuga anastomótica (FA), infección del sitio operatorio (ISO), tránsito intestinal posoperatorio, infección por Clostridium difficile (CD) y estadía hospitalaria. Para el análisis estadístico se realizaron modelos bivariados y multivariados. Resultados: La FA fue más frecuente en el grupo PMC (7,38% vs. 0%, p = 0,011). En colectomías del lado izquierdo, la diferencia más marcada en las FA de ambos grupos fue en anastomosis del recto medio, sin casos en el grupo PMC+AO (0% vs. 50%, p = 0,019). En colectomías derechas, la FA fue similar para ambos grupos. Hubo más ISO en el grupo PMC (4,7% vs. 0%, p = 0,037). La recuperación del tránsito intestinal fue más rápida para el grupo PMC+AO, determinando menor estadía hospitalaria (3,98 días vs. 6,39 días, p = 0,001). El grupo PMC+AO se asoció a mayor tasa de colitis por CD (4,48% vs. 0,67%, p = 0,008). Discusión y Conclusión: El uso de la preparación intestinal con antibióticos orales podría ayudar a prevenir la FA en las colectomías izquierdas y evitar las ISO, favoreciendo la recuperación del tránsito intestinal, reduciendo la estadía hospitalaria. La asociación a CD debe examinarse en estudios más amplios.
Aim: To evaluate postoperative complications and clinical evolution in patients undergoing colectomies and anastomosis with two preoperative strategies, mechanical bowel preparation alone (MBP) and mechanical bowel preparation with oral antibiotics (MBP+OA). Materials and Method: Retrospective study, with defined inclusion and exclusion criteria. Variables studied: preoperative demographic characteristics, surgical intervention, anastomotic location, anastomotic leakage (AL), surgical site infection (SSI), postoperative intestinal transit, Clostridium difficile (CD) infection and hospital stay. Statistical analysis, bivariate and multivariate models were performed. Results: 216 patients studied, 149 were MBP group and 67 MBP+OA group. The group MBP had higher rates of AL (7.38% vs. 0%, p = 0.011). For left-sided colectomies, AL rate in both groups had a higher difference in the middle rectum, with no cases in the MBP+OA group (0% vs. 50%, p = 0.019). For right colectomies, the AL rates were similar in both groups. SSI was higher in MBP group (4.7% vs. 0%, p = 0.037). The bowel transit recovery was faster for MBP+OA group, determining less hospital stay (3.98 days vs. 6.39 days, p = 0.001). The group MBP+OA had a higher rate of CD colitis, 4.48% (p = 0.008). Discussion and Conclusion: These results suggest that preoperative oral antibiotic with mechanical bowel preparation could help to prevent anastomotic leaks in left-sided colectomies, also avoid surgical site infection, favoring the recovery of postoperative bowel transit, reducing hospital stay. The association to CD should be examined in larger studies.

Introducción: la gastritis enfisematosa es una patología poco común pero con alta mortalidad, su presentación clínica es insidiosa, la imagen por tomografía se distingue por un patrón de burbujas lineales con engrosamiento de la pared gástrica. Caso clínico: paciente masculino de 78 años, previamente sano, funcional, que fue ingresado por fractura pertrocantérica de cadera izquierda, quien durante la hospitalización presenta delirium hiperactivo, distención abdominal con disminución de perístalsis además de hipotensión arterial, se realiza tomografía abdominal con evidencia de dilatación gástrica y múltiples burbujas de aire en pared. Es manejado con antibiótico de amplio espectro, fluidoterapia y nutrición parenteral, con respuesta favorable.Conclusiones: la edad avanzada no conlleva por sí misma un peor pronóstico de la enfermedad, la evidencia apoya que un diagnóstico precoz y la intervención terapéutica temprana, son las medidas que han demostrado ser efectivas para la disminución de la mortalidad en pacientes con gastritis enfisematosa
Introduction: Emphysematous gastritis is an uncommon pathology but with high mortality, its clinical presentation is insidious, the tomography image is distinguished by a pattern of linear bubbles with thickening of the gastric wall.Background: This is a 78-year-old male, previously healthy, functional, who was admitted for pertrochanteric fracture of the left hip, who during hospitalization presented hyperactive delirium, abdominal distention with decreased perstalsis in addition to arterial hypotension, an abdominal tomography with evidence of gastric dilation and multiple air bubbles in the wall. He is managed with a broad spectrum antibiotic, fluid therapy and parenteral nutrition, with a favorable response.Conclusions: Advanced age does not in itself lead to a worse disease prognosis, the evidence supports that early diagnosis and early therapeutic intervention are the easures that have proven to be more effective in reducing mortality in patients with emphysematous gastritis.

Introdução: A pandemia de COVID-19 fez aumentar a demanda de medicamentos utilizados em hospitais, como a Ceftazidima + Avibactam. Nesse contexto, a Central de Misturas Intravenosas (CMIV) de um hospital público universitário passou a unitarizar as doses prescritas. O objetivo deste trabalho foi avaliar o impacto da unitarização no consumo deste antibacteriano de alto custo em um hospital público universitário. Métodos: Trata-se de uma análise farmacoeconômica de custos diretos, sobre a utilização de frascos-ampola de Ceftazidima + Avibactam no período de 01/07/2020 a 31/05/2021. Foram unitarizadas todas as doses que correspondiam a uma fração da dose total do frasco-ampola, em Cabine de Segurança Biológica classe II B2. Os frascos-ampola foram utilizados à exaustão, através do compartilhamento e organização dos horários de manipulação. Resultados: O número total de preparos realizados pela CMIV do referido hospital no período foi de 837. O consumo projetado sem a centralização dos preparos seria de 837 (um frasco por dose). Entretanto, o consumo real foi de 437 frascos. A eficiência de unitarização foi de 101%, com economia real de 400 frascos (R$ 244.832,00) para a instituição. Conclusão: A pandemia de COVID-19 sobrecarregou os sistemas de saúde do mundo todo, sendo que a atuação farmacêutica foi fundamental para garantir o acesso aos medicamentos essenciais. A CMIV assumiu a unitarização da Ceftazidima + Avibactam, antibiótico em risco de desabastecimento, gerando um consumo 47,8% menor, contribuindo para o acesso deste medicamento de forma ininterrupta durante os 11 meses avaliados na referida instituição.
Introduction: COVID-19 pandemic has increased the demand for drugs used in hospitals, such as Ceftazidime + Avibactam. In this context, the Central of Intravenous Admixtures (CMIV) of a public university hospital started to unitarize the prescribed doses. The objective of this study was to evaluate the impact of unitarization on the consumption of this high-cost antibacterial in a public university hospital. Methods: This is a pharmacoeconomic analysis of direct costs, on the Ceftazidime + Avibactam vials use, in the period from 07/01/2020 to 05/31/2021. All doses that corresponded to a fraction of the entire vial were unitarized in a Class II B2 Biological Safety Cabin. The vials were used to exhaustion, by sharing them, and organizing the manipulation schedules. Results: The total number of preparations made by the CMIV of that hospital in the period was 837 doses. The projected consumption would be 837 vials (one vial per dose). However, the actual consumption was 437 vials. The unitarization efficiency was of 101%, with real savings of 400 vials (R$ 244,832.00) for the institution. Conclusion: COVID-19 pandemic has overburdened health systems around the world, and pharmaceutical actions have been fundamental to guaranteeing access to essential medicines. CMIV took over the unitarization of Ceftazidime + Avibactam, an antibiotic at risk of shortages, leading to a 47.8% lower consumption, contributing to uninterrupted access to this drug during the 11 months evaluated at that institution.

INTRODUCCIÓN: La neumonía asociada a ventilación mecánica (NAVM) es frecuente en pacientes críticos con COVID-19. Su diagnóstico precoz es fundamental para su pronóstico. OBJETIVO: Demostrar la utilidad del panel FilmArray Pneumo (PFA-P) en la confirmación o descarte de NAVM en estos pacientes. MÉTODOS: Estudio retrospectivo de 71 pacientes críticos con COVID-19 con sospecha de NAVM en quienes se realizó cultivos y PFA-P para confirmación diagnóstica. Se describen las características clínicas, microbiología y mortalidad. Se define la validez y seguridad de PFA-P. RESULTADOS: El uso de FAP-P y cultivos descartó NAVM en 29 pacientes (40,8%). En 41 pacientes se confirmó NAVM y la mortalidad a 30 días fue 48,8%. Se estudiaron 48 muestras, los cultivos fueron positivos en 30 (62,5%) y se detectaron 33 bacterias, PFA-P detectó 32 de estas 33 bacterias; 37 bacterias fueron detectadas exclusivamente por PFA-P. Las bacterias prevalentes fueron Klebsiella pneumoniae (31,4%) Pseudomonas aeruginosa (21,4%) y Acinetobacter calcoaceticusbaumannii (14,2%). La sensibilidad, especificidad, valor predictor positivo y valor predictor negativo de PFA-P con respecto a cultivos fue 96,9%, 92,5%, 46,4% y 99,8, respectivamente. Un paciente tuvo NAVM por Burkholderia cepacia bacteria no detectada por FAP-P. CONCLUSIONES: La FAP-P es una técnica molecular eficaz para descartar y diagnosticar la NAVM permitiendo una suspensión rápida de los antimicrobianos o un tratamiento dirigido temprano.
BACKGROUND: Ventilator-associated pneumonia (VAP) is frequent in critical COVID-19 patients. Its early diagnosis is essential for its prognosis. AIM: To demonstrate the usefulness of the FilmArray Pneumo panel (FAP-P) in confirming or ruling out VAP in these patients. METHODS: Retrospective study of 71 critical COVID-19 patients with suspected VAP in whom cultures and FAP-P were performed for diagnostic confirmation. Clinical characteristics, microbiology and mortality are described. The validity and safety of FAP-P is defined. RESULTS: The use of FAP-P and cultures ruled out VAP in 29 patients (40.8%). In 41 patients, VAP was confirmed and the 30-day mortality was 48.8%. Forty-eight samples were studied, the cultures were positive in 30 (62.5%) and 33 bacteria were detected, FAP-P detected 32 of these 33 bacteria; 37 bacteria were exclusively detected by PFA-P. The most prevalent bacteria were Klebsiella pneumoniae (31.4%), Pseudomonas aeruginosa (21.4%) and Acinetobacter calcoaceticus-baumannii (14.2%). The sensitivity, specificity, positive predictive value and negative predictive value of FAP-P with respect to cultures were 96.9%, 92.5%, 46.4% and 99.8%, respectively. One patient had VAP due to Burkholderia cepacia bacteria not detected by FAP-P. CONCLUSIONS: FAP-P is an effective molecular technique to rule out and diagnose VAP, allowing rapid suspension of antibiotics or early targeted treatment.

The utilization of antimicrobials in animal production, causes selection of resistant bacteria. The objective of this study was to compare the utilization of alternatives in association with preventive antibiotic therapy in swine feed during the growing and finishing phases. 1,045 animals were used from 60 to 190 days of age and were subjected to six treatments with 16 repetitions as follows: 1) antibiotic free; 2) antibiotics; 3) prebiotic; 4) probiotic; 5) essential oils; and 6) organic acid. Animals were weighted, and clinical history was recorded including mortality and diarrhea. At the abattoir, pneumonia index and gastric ulcers were investigated. The cost for each treatment was discussed. No difference between treatments were observed (P>0.05) regarding feed conversion rate (2.64±0.03), overall average weight gain (107.06±0.9kg), average daily weight gain (856.49±7.7g) and carcass weight (92.4±0.7kg). The application injectable drugs in animals presenting clinical symptoms, represented US$ 0.56/intervention, without difference between the treatments (P>0.05). Furthermore, independently of the treatment, high frequency of pneumonia was observed (>0.90). No difference for the degree of gastric ulcer nor feces consistency were observed (P>0.05). The utilization of antibiotic therapy and alternatives to antibiotics in feed did not produce benefits to the production indices and sanitary performances of the animals.(AU)
A utilização de antimicrobianos na produção animal provoca seleção de bactérias resistentes. O objetivo do estudo foi comparar a utilização de alternativas associadas à antibioticoterapia preventiva na alimentação de suínos nas fases de recria e de terminação. Foram utilizados 1.045 animais de 60 a 190 dias de idade, submetidos a seis tratamentos com 16 repetições, como segue: 1) sem antibióticos; 2) com antibióticos; 3) prebióticos; 4) probióticos; 5) óleos essenciais; e 6) ácidos orgânicos. Os animais foram pesados, e a história clínica foi registrada, incluindo mortalidade e diarreia. No abatedouro, foram investigados índices de pneumonia e úlceras gástricas. O custo de cada tratamento foi discutido. Não houve diferença entre os tratamentos (P>0,05) em relação à taxa de conversão alimentar (2,64 ± 0,03), ao ganho de peso médio geral (107,06 ± 0,9kg), ao ganho de peso médio diário (856,49 ± 7,7g) e ao peso de carcaça (92,4 ± 0,7kg). A aplicação de medicamentos injetáveis em animais com quadro clínico representou US$ 0,56/intervenção, sem diferença entre os tratamentos (P>0,05). Além disso, independentemente do tratamento, foi observada alta frequência de pneumonia (>0,90). Não foi observada diferença para o grau de úlcera gástrica nem na consistência das fezes (P>0,05). A utilização de antibioticoterapia e de alternativas aos antibióticos na ração não trouxe benefícios aos desempenhos zootécnico e sanitário dos animais.(AU)

Resumen Los antimicrobianos corresponden al grupo de medicamentos más utilizados en Unidades de Cuidados Intensivos Neonatales; no obstante, su uso ha sido asociado a constantes errores de medicación en la práctica clínica. Paradojalmente, aún no existe consenso en torno a la administración adecuada de estos medicamentos y existen importantes brechas de conocimiento en torno a los procesos de dosificación, administración y manipulación de antimicrobianos en esta población. Con el fin de mejorar el uso de antimicrobianos, disminuir errores y optimizar los resultados clínicos en el recién nacido, la presente revisión tiene por objetivo entregar recomendaciones y servir de guía para la correcta preparación de aquellos antimicrobianos de mayor relevancia en neonatología.
Abstract Antimicrobials are among the most commonly prescribed classes of medications in Neonatal Intensive Care Units; however, its use has been constantly associated with a number of medication errors in clinical practice. In contrast to this situation, there is no common agreement when it comes to determining the right dosing, administration, or handling of antibiotics in this population. In order to help improve the use of antibiotics, decrease the rate of medication errors and optimize clinical results in the newborn, this review aims to provide recommendations to support and guide the correct preparation of some of the most relevant antibiotics used in neonatal wards.
