ABSTRACT
La faringoamigdalitis aguda (FAA) en el adulto es una de las enfermedades infecciosas más comunes en la consulta del médico de familia. La etiología más frecuente es viral. Dentro de la etiología bacteriana, el principal agente responsable es Streptococcus pyogenes o estreptococo β-hemolítico del grupo A (EBHGA), causante del 5-30% de los casos. En el manejo diagnóstico las escalas de valoración clínica, para predecir la posible etiología bacteriana, son una buena ayuda para seleccionar a qué pacientes se deben practicar las técnicas de detección rápida de antígeno estreptocócico. Es conocido que, en general, sin estas técnicas, se tiende al sobrediagnóstico de FAA estreptocócica, con la consiguiente prescripción innecesaria de antibióticos, muchas veces de amplio espectro. Así, con el manejo de las escalas y la técnica de diagnóstico rápido, elaboramos los algoritmos de manejo de la FAA. Los objetivos del tratamiento son acelerar la resolución de los síntomas, reducir el tiempo de contagio y prevenir las complicaciones supurativas locales y no supurativas. Los antibióticos de elección para el tratamiento de la FAA estreptocócica son penicilina y amoxicilina. La asociación de amoxicilina y clavulánico no está indicada en el tratamiento inicial en la infección aguda. Los macrólidos tampoco son un tratamiento de primera elección; su uso debe reservarse para pacientes con alergia a la penicilina. Es importante en nuestro país adecuar tanto el diagnóstico de la FAA bacteriana y la prescripción de antibióticos a la evidencia científica disponible. La implantación de protocolos de actuación en las farmacias comunitarias puede ser de utilidad para identificar y cribar los casos que no requieran tratamiento antibiótico (AU)
The acute pharyngotonsillitis (APT) in adults is one the most common infectious diseases in the family physicians surgery. The most frequent etiology is viral. Within the bacterial etiology, the main agent responsible is Streptococcus pyogenes or streptococcus β-GROUP A hemolytic (EBHGA), causing 5-30% of cases. In the diagnostic management, to predict the possible bacterial etiology, clinical evaluation scales are a good help for selecting which patients should undergo quick detection techniques for the streptococcic antigen. It is known that, in general, without these techniques streptococcic APT tends to be overdiagnosed, with the ensuing unnecessary prescription for antibiotics, often broad-spectrum. Thus, with the management of the steps and the quick diagnosis technique, we can draw up algorithms for managing APT. The objectives of the treatment are to accelerate the resolution of symptoms, reduce contagion time and prevent local suppurative and non-suppurative complications. The antibiotics of choice for treating streptococcic APT are penicillin and amoxicillin. The combination of amoxicillin and clavulanic acid is not indicated for the initial treatment of acute infection. Macrolides are not a first-choice treatment either; their use must be reserved for patients with allergy to penicillin. In our country it is important to adapt both the diagnosis of bacterial APT and the prescription of antibiotics to the scientific evidence available. The implementation of protocols of action in community pharmacies may be of use in identifying and screening cases that do not require antibiotic treatment (AU)

La infección por Streptococcus agalactiae, estreptococo grupo B (EGB), continúa siendo la causa más frecuente de sepsis neonatal de etiología bacteriana. En 2003, las Sociedades Españolas de Ginecología y Obstetricia, Neonatología, Enfermedades Infecciosas y Microbiología Clínica, Quimioterapia y Medicina Familiar y Comunitaria publicaron recomendaciones actualizadas para la prevención de la infección neonatal precoz por EGB. En ellas se recomendaba la identificación de gestantes portadoras de EGB mediante cultivo de muestra de exudado vaginorrectal realizado en las 35-37 semanas de gestación y la administración de profilaxis antibiótica intraparto (PAI) a todas las gestantes colonizadas. En estas nuevas recomendaciones se actualizan los métodos microbiológicos para realizar la identificación de portadoras de EGB y la técnica de sensibilidad a antibióticos; se revisan los antibióticos de primera línea que pueden usarse para PAI (penicilina, ampicilina, cefazolina) y sus alternativas (clindamicina y vancomicina); se clarifica el significado de la presencia de EGB en orina, incluyendo criterios para el diagnóstico de infección urinaria y bacteriuria asintomática por EGB en la embarazada; se define el uso de PAI en la amenaza de parto prematuro y rotura prematura de membranas, y se revisa el manejo del recién nacido en relación con el estado de portadora de EGB de la madre. Estas recomendaciones solo son válidas para la prevención de la infección neonatal precoz por EGB, y no son efectivas frente a la infección neonatal tardía. Tras la aplicación generalizada de la PAI, la incidencia de la sepsis neonatal precoz por EGB ha disminuido (..) (AU)
Group B streptococci (GBS) remain the most common cause of early onset neonatal sepsis. In 2003 the Spanish Societies of Obstetrics and Gynaecology, Neonatology, Infectious Diseases and Clinical Microbiology, Chemotherapy, and Family and Community Medicine published updated recommendations for the prevention of early onset neonatal GBS infection. It was recommended to study all pregnant women at 35-37 weeks gestation to determine whether they were colonised by GBS, and to administer intrapartum antibiotic prophylaxis (IAP) to all colonised women. There has been a significant reduction in neonatal GBS infection in Spain following the widespread application of IAP. Today most cases of early onset GBS neonatal infection are due to false negative results in detecting GBS, to the lack of communication between laboratories and obstetric units, and to failures in implementing the prevention protocol. In 2010, new recommendations were published by the CDC, and this fact, together with the new knowledge and experience available, has led to the publishing of these new recommendations. The main changes in these revised recommendations include: microbiological methods to identify pregnant GBS carriers and for testing GBS antibiotic sensitivity, and the antibiotics used for IAP are updated; The significance of the presence of GBS in urine, including (..)

The main changes in these revised recommendations include: microbiological methods to identify pregnant GBS carriers and for testing GBS antibiotic sensitivity, and the antibiotics used for IAP are updated; The significance of the presence of GBS in urine, including criteria for the diagnosis of UTI and asymptomatic bacteriuria in pregnancy are clarified; IAP in preterm labour and premature rupture of membranes, and the management of the newborn in relation to GBS carrier status of the mother are also revised. These recommendations are only addressed to the prevention of GBS early neonatal infection, are not effective against late neonatal infection.

It has been a significant reduction in neonatal group B streptococcus (GBS) infection in Spain following the widespread application of intrapartum antibiotic prophylaxis. In 2010, new recommendations have been published by the CDC and this fact, together with the new knowledge and experience available, has driven to the participating scientific societies publishing these new recommendations. In these recommendations is advised to study all pregnant women at 35-37 gestation weeks` to determine if they are colonized by GBS and to administer intrapartum antibiotic prophylaxis (IAP) to all colonized mothers. Microbiological methods to identify pregnant GBS carriers are updated and intrapartrum antibiotic prophylaxis in preterm labour and premature rupture of membranes and the management of the newborn in relation to GBS carrier status of the mother are also revised.

Como consecuencia aplicación de la profilaxis antibiótica intraparto ha ocurrido una importante reducción de la infección neonatal por estreptococo grupo B en nuestro país. En 2010 se han publicado nuevas recomendaciones por los CDC y este hecho, junto con los nuevos conocimientos disponibles, ha llevado a las sociedades participantes a publicar estas nuevas recomendaciones. En ellas se mantiene el criterio de administrar profilaxis intraparto a todas las embarazadas colonizadas por EGB, se actualizan las técnicas de diagnostico de portadoras y se clarifica la actuación frente al parto prematuro y a los recién nacidos a riesgo de infectarse(AU)
