RESUMEN
OBJECTIVES: Cri du chat syndrome is a genetic alteration associated with some oral pathologies. However, it has not been described previously any clinical relationship between the periodontal disease and the syndrome. The pur-pose of this comparative study was to compare periodontopathogenic flora in a group with Cri du chat syndrome and another without the síndrome, to assess a potential microbiological predisposition to suffer a periodontitis.Study DESIGN: The study compared nineteen subjects with Cri du chat Syndrome with a control group of nineteen patients without it. All patients were clinically evaluated by periodontal probing, valuing the pocket depth, the clinical attachmente level and bleeding on probing. There were no significant differences between both groups. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola were detected by multiplex-PCR using 16S rDNA (microIDENT).RESULTS: When A. actinomycetemcomitans, P. gingivalis, P. intermedia and T. denticola were compared, no statis-tically significant differences were found between the two groups (p > 0.05). The value of T. forsythia was signifi-cantly higher for Cri du chat syndrome (31.6%) than for the control group (5.3%). The odds ratio for T. forsythia was 8.3.CONCLUSIONS: In the present study T. forsythia is associated with Cri du chat syndrome subjects and not with healthy subjects

External apical root resorption (EARR) is a frequent iatrogenic problem following orthodontic treatment in endodontically-treated teeth, about which the literature reports substantial variability in post-orthodontic treatment EARR responses. The main focus of the present study is to clarify whether variants in the interleukin-1 receptor antagonist gene coding for the IL-1ra protein have a positive/negative influence on EARR of endodontically-treated teeth. Ninety-three orthodontic patients were genetically screened for a single nucleotide polymorphism (SNP:rs419598) in the IL1 cluster. The sample was classified into 2 groups: group 1 (affected-group) showed radiographic EARR of more than 2mm; group 2 (control-group), had no EARR or EARR ≤ to 2mm following orthodontic treatment on root-filled teeth. Logistic regression analysis was performed to obtain an adjusted estimate between the SNPs studied and EARR. Genotype distributions, allelic frequencies, adjusted odds ratios (OR) and 95% confidence intervals were also calculated. We found that subjects homozygous [1/1(TT)] for the IL1RN gene [OR:10.85; p=0.001;CI:95%] were at risk of EARR in root-filled teeth. Genetic variants in the antagonist axis balance of the IL1RN (rs419598) have a direct repercussion on the predisposition to post-orthodontic EARR in root-filled teeth. Variants in allele 1 of the interleukin-1 receptor antagonist gene(rs419598) are associated(p=0.001**) with an increased risk of suffering post-orthodontic EARR in root-filled teeth.

La microbiología clínica es hoy día una especialidad bien consolidada en nuestro país y cuyo desarrollo ha estado necesariamente vinculado a la mejora en el diagnóstico, tratamiento y prevención de las enfermedades infecciosas. En torno a ella, se han ido formando a lo largo del tiempo estructuras asistenciales, docentes y de investigación, y una sociedad científica conjunta con los especialistas en enfermedades infecciosas (Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica) que, a su vez, edita la revista ENFERMEDADES INFECCIOSAS Y MICROBIOLOGÍA CLÍNICA, organiza congresos, reuniones, grupos de estudio, un programa de control de calidad, etc. Nuevas perspectivas de futuro (identificación de nuevos microorganismos patógenos, cambios metodológicos, calidad y rapidez diagnóstica, infecciones nosocomiales, desarrollo de resistencia a los antimicrobianos, etc.) mantienen la vigencia de nuestra especialidad y constituyen un área de conocimiento bien definido con razón de ser propia
Clinical microbiology today is a well-established specialty in Spain whose development has necessarily been linked to improvements in the diagnosis, treatment and prevention of infectious diseases. Over time, clinical, teaching, and research structures have been organized around these diseases. In addition, a scientific society for specialists in infectious diseases (Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica) has been set up, which in turn, publishes the journal ENFERMEDADES INFECCIOSAS Y MICROBIOLOGÍA CLÍNICA, and organizes congresses, meetings, working groups and a quality control program, etc. Clinical microbiologists will continue to be needed to meet future challenges (identification of new pathogenic microorganisms, methodological changes, diagnostic quality and speed, nosocomial infections, the development of antimicrobial resistance, etc.), which constitute a well-defined area of knowledge specific to our specialty

The infection of the oral cavity is a common public health problem and constant cause for antibiotic prescription, with 10% of antibiotics used to treat this problem. However, few studies have so far aimed to determine its incidence. Added to this, its relationship with certain sytemic diseases (cardiac, endocrine, etc) confers this pathology vital importance. In spite of the frequency and importance of odontogenic infection, the current dispersion in criteria regarding key aspects in classification, terminology and therapeutic recommendations is noticeable. The main objective of this document, compiled as a consensus statement by specialists in microbiology and odontology, is to establish useful recommendations for all of those involved in the clinical management of this pathology. Special attention has been placed on the rise in bacterial resistance observed over the last years, specifically the proliferation of betalactamase producing strains. Another important factor causing the resistance to appear is lack of therapeutic compliance, specially what regards dosage and treatment duration. Therefore, this pathology constitutes a complex problem which requires the instauration of broad spectrum antimicrobials, well tolerated and a convenient posology so that patients receive the adequate dose over the necessary period. High doses of amoxicillin/clavulanate (2000 mg/125 mg) have showed good results and power to overcome resistance. Other agents such as metronidazole and clindamycin, followed by de claritromycin and azithromycin have also proved to be active against most of microorganisms responsible for odontogenic infection.

Las infecciones de la cavidad bucal son un problema de salud pública frecuente y motivo constante de prescripción antibiótica; el 10% de los antibióticos se emplean para tratar este problema. Sin embargo, hasta la fecha son pocos los estudios realizados para determinar su incidencia. Asímismo, su relación con ciertas enfermedades sistémicas (cardiacas, endocrinas, etc...) confiere a estas patologías una importancia vital. A pesar de la reconocida frecuencia e importancia de las infecciones odontogénicas, llama la atención la actual dispersión de criterio en varios aspectos referentes a su clasificación, terminología y recomendaciones terapéuticas. El objetivo principal de este documento, realizado con el consenso de especialistas en microbiología y odontología, es establecer unas recomendaciones útiles para todos los profesionales implicados en el manejo clínico de estas patologías. Recibe especial atención el aumento de la prevalencia de resistencias bacterianas observado durante los últimos años y, en concreto, la proliferación de cepas productoras de betalactamasas. Otro factor causal importante de la aparición de resistencias es la falta de cumplimiento terapéutico, en especial en lo que respecta a la dosis y a la duración del tratamiento. Así pues, estas patologías constituyen un problema complejo cuyo abordaje requiere la instauración de antimicrobianos de amplio espectro, con adecuados parámetros farmacocinéticos, con buena tolerancia y una posología cómoda que permita que el paciente reciba la dosis adecuada durante el tiempo necesario. Amoxicilina/ácido clavulánico a dosis altas (2000mg/ 125mg) ha demostrado buenos resultados y capacidad para superar resistencias. Otros agentes como metronidazol y clindamicina, seguidos de claritromicina y azitromicina han demostrado también ser activos frente a la mayoría de los microorganismos responsables de las infecciones odontogénicas (AU)

La naturaleza polimicrobiana de las infecciones odontógenas así como la heterogeneidad de los cuadros clínicos asociados son consecuencia de la diversidad de la microbiota bucal y de la complejidad anatómica y funcional de la cavidad oral. Así mismo, estos procesos pueden dar lugar a múltiples complicaciones que pueden limitarse a afecciones locales o derivar hasta compromisos sistémicos. En el tratamiento farmacológico de estas infecciones es crucial la elección del antibiótico y la pauta posológica más eficaces. La farmacodinamia proporciona los parámetros que hacen posible valorar como varía la actividad de los antibióticos en función del tiempo. Como norma general, en el manejo inicial de las infecciones orofaciales en el adulto, incluidas las infecciones odontógenas, se utilizará amoxicilina/ac. Clavulánico en dosis de 875 mg de amoxicilina y 125 mg de ac. clavulánico pautado cada 8 horas. El cumplimiento terapéutico es clave para evitar la aparición de resistencias, por lo que se ha de maximizar la aceptación por parte de los pacientes. En este sentido se ha demostrado que la nueva presentación de 2000/125 mg de Augmentine Plus pautado cada 12 horas tanto en profilaxis como tratamiento disminuye significativamente la tasa de complicaciones infecciosas derivada de la extracción del tercer molar (AU)
The polymicrobial nature of the odontogenic infections as well as the variety of associated conditions are a consequence of the diversity of the buccal microbiota and the anatomical and functional complexity of the oral cavity. In addition to this, all these processes can give way to multiple complications which range from the local to the systemic level. The appropriate choice of antibiotic and posology is crucial in the successful management of these infections. Pharmacodyna-mics provides those parameters that make it possible to assess how antibiotics activity varies in time. As a general rule, the first step in the initial management of orofacial infections in adults, included odontogenic infections, will be the administration of 875 mg of amoxicillin and 125 mg of clavulanic every 8 hours. Therapeutic compliance is paramount to avoid resistance, therefore patient's acceptance must be sought. In this sense, it has been proved that Augmentine Plus (2000/125) every twelve hours both as profylaxis and as treatment significantly decreases the rate of infective complications associated to extraction of the third molar (AU)
