Checklist of the cestode parasites of wild birds of Argentina.

An annotated checklist of the cestode parasites of Argentinean wild birds is presented, as the result of a compilation of parasitological papers published between 1900 and April 2021. This review provides data on hosts, geographical distribution, sites of infection, location of material deposited in helminthological collections, references and taxonomic comments. A host/parasite list is also provided. During this period, 38 papers were published that gather information about 34 cestode nominal species and 11 taxa identified at generic level, belonging to three orders, ten families and 35 genera. The highest number of cestode taxa was recorded in the family Hymenolepididae, with 12 nominal species and two taxa identified at generic level, followed by Dilepididae, with eight nominal species and three taxa identified at generic level. Of the 1042 species of birds reported in Argentina, only 29 (2.8%) were reported as hosts of adult cestodes. The families of birds with the highest number of reported taxa were Laridae and Anatidae, with 20 and 14 taxa, respectively.

Aspectos clínicos y bacteriológicos de las mastoiditis agudas como complicación de otitis media aguda y crónica en pediatría, Experiencia en 10 años / Clinical and bacteriological features of acute mastoiditis as a complication of acute and chronic otitis media in pediatrics. A 10-years experience

Antecedentes. Cualquier paciente pediátrico o adulto que presente otitis media aguda (OMA) u otitis media crónica (OMC), particularmente colesteatomatosa, puede desarrollar complicaciones intratemporales y endocraneales, especialmente mastoiditis aguda (MA). Objetivo. Describir las características clínicas y bacteriología de los pacientes asistidos por MA como complicación de OMA y OMC. Lugar de aplicación: Servicio de Otorrinolaringología. Hospital de Pediatría Juan P. Garrahan. Diseño. Descriptivo, retrospectivo, transversal y observacional. Población. Pacientes con mastoiditis aguda por OMA y por OMC asistidos en el Servicio de ORL durante 10 años. Material y métodos. Revisión de historias clínicas de todos los pacientes tratados entre enero de 1999 y diciembre de 2008. Resultados. Se estudiaron 57 pacientes con MA, 40/57 por OMA y 17/57 por OMC. Hubo 40 niños hospitalizados con signos y síntomas de MA por OMA. Se diagnosticó complicación endocraneal en el 12,5% (5/40) de los casos. Los aislamientos bacterianos más frecuentes fueron Streptococcus pyogenes, Streptococcus pneumoniae, H. influenzae y Turicella otitidis. Se registraron 17 casos de niños hospitalizados con diagnóstico de MA y OMC. Ocurrieron complicaciones supurativas intracraneales en el 35,3% (6/17) de los casos. Los aislamientos bacterianos más frecuentes fueron las enterobacterias, P. aeruginosa y los gérmenes anaerobios. Conclusión. El diagnóstico de tipo y estadio de otitis media previa o coexistente a la complicación es fundamental para encarar el tratamiento antimicrobiano empírico inicial, sospechar complicaciones endocraneales asociadas y proponer procedimientos quirúrgicos menores, medianos o mayores oportunamente (AU)

Background. Any pediatric or adult patient presenting with acute otitis media (AOM) or chronic otitis media (COM), especially cholesteatomatous, may develop intratemporal and intracranial complications, mainly acute mastoiditis (AM). Objective. To describe the clinical and bacteriological features of patients seen for AM as a complication of AOM and COM. Setting: Department of Otolaryngology, Hospital de Pediatría Juan P. Garrahan. Design. A descriptive, retrospective, cross-sectional, observational study. Population. Patients with AM because of AOM and COM seen at the Department of Otolaryngology over a 10-year period. Material and methods. Review of the clinical charts of all patients treated between January 1999 and December 2008. Results. 57 Patients with AM, 40/57 due to AOM and 17/57 due to COM, were evaluated. Forty children were admitted to hospital with signs and symptoms of AOM-related AM. Intracranial complications were observed in 12.5% (5/40) of the patients. The most frequently isolated pathogens were Streptococcus pyogenes, Streptococcus pneumoniae, H. influenzae, and Turicella Otitidis. Seventeen children were hospitalized because of COM-related AM. Suppurative intracranial complications occurred in 35.3% (6/17) of the cases. The most frequently isolated pathogens were Enterobacteriaceae, P. aeruginosa, and anaerobic bacteria. Conclusion. The diagnosis of type and stage of otitis media prior to or coexisting with the complication is essential to address the initial empirical antimicrobial treatment, associated intracranial complications should be suspected and minor, intermediate, or major surgical procedures should be proposed at the appropriate time (AU)
