Brote de eritema infeccioso en un centro de salud urbano

ObjetivosAnalizar las características clínicas y serológicas de un brote de eritema infeccioso en pacientes que acudieron a las 2 consultas de pediatría del Centro de Salud de Soria Norte.DiseñoEstudio descriptivo, transversal.EmplazamientoConsultas de pediatría del Centro de Salud de Soria Norte.PacientesUna vez sospechado el brote, se estudiaron niños con clínica sugestiva de eritema infeccioso que acudieron sucesivamente a las 2 consultas de pediatría de Soria Norte durante los meses de abril a agosto de 1998 y consintieron en la práctica de analítica.IntervencionesSe realizó registro de síntomas clínicos, serología, hemograma y evolución de 25 pacientes.ResultadosSe estudiaron 25 pacientes del total de casos, confirmando nuestra sospecha diagnóstica en un 84% de los casos. No se observaron diferencias en ambos sexos, con una edad media de 6,1 años, y DE, 2,015. El signo clínico más constante fue el exantema en mejillas, presente en un 100% de los casos confirmados, seguido de exantema en tronco y extremidades en un 57,1%, adenopatías en un 9,5% y fiebre en un 4,7%. En ningún caso se objetivaron complicaciones.ConclusionesLos resultados de este trabajo permiten confirmar la existencia de un brote de eritema infeccioso en nuestro medio. Consideramos útil la confirmación serológica para constatar la presencia de un brote y poder realizar un enfoque terapéutico (frente a complicaciones posibles) y preventivo adecuado. Destacamos el carácter, en general, benigno de la enfermedad.ObjectivesTo analyse the clinical and serological characteristics of an outbreak of infectious erythema in patients attending the two paediatrics clinics at the Soria Norte Health Centre.DesignCross-sectional, descriptive study.SettingPaediatrics clinics of the Soria Norte Health Centre.PatientsOnce the outbreak was suspected, the study was conducted on children with a clinical picture suggesting infectious erythema who attended successively two Soria Norte paediatrics clinics between April and August 1998 and who consented to the analyses.InterventionsThe clinical symptoms, serology, haemogram and evolution of 25 patients were recorded.Results25 patients of the total were studied and diagnostic suspicion was confirmed in 84% of the cases. There were no differences between sexes, with an average age of 6.1, SD 2.015. The most constant clinical sign was exanthem on the cheeks, present in 100% of the cases confirmed, followed by 57% exanthem on the trunk and limbs, 9.5% adenopathies and 4.7% temperature. No complications were found in any case.ConclusionsThe results of this study confirm the existence of an outbreak of infectious erythema in our area. Serological confirmation of an outbreak is useful and can lay the basis for a proper therapeutic and preventive focus (against possible complications). We highlight the generally benign nature of the disease

Cervicofacial lymphadenitis due to Mycobacterium mantenii: rapid and reliable identification by MALDI-TOF MS.

Mycobacterium mantenii is a scotochromogenic non-tuberculous mycobacterium (NTM). Van Ingen et al. [1] described this bacterium for the first time in 2009 from the cervical lymph node samples from two immunocompetent children, respiratory samples from two adults and a water sample from Zambia. Since then, only two cases of disseminated M. mantenii infection have been described in immunocompromised patients [2], [3]. This mycobacterium has also been isolated in environmental samples from Ghana [4] and the Czech Republic [5]. In this report, two new cases involving immunocompetent girls with cervicofacial lymphadenitis due to M. mantenii are presented, and the reliability of matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) for identifying M. mantenii is evaluated.S

In vitro activity of 79 antimicrobial agents against Corynebacterium group D2.

Corynebacterium group D2 (CGD2) is involved in urinary tract infections in patients with underlying predisposing factors. This microorganism is highly resistant to a number of antimicrobial agents. We tested the activities of 79 antimicrobial agents against CGD2. beta-Lactams, aminoglycosides, and macrolides were ineffective. Fluorinated quinolones showed irregular activities, ofloxacin being the most active one. Doxycycline, rifampin, and mainly glycopeptides (vancomycin and teicoplanin) were the most active antibiotics against CGD2
