ABSTRACT
ABSTRACT Streptococcus constellatus is a gram-positive coccus member of the Streptococcus anginosus group (SAG). It can be found in the oral flora, and may cause abscess more commonly in the gastrointestinal tract, lungs, and heart. Brain abscesses are severe neurological infections with high mortality rates. Streptococcus species other than S. pneumoniae are rare causes of brain abscesses. This case report highlights a severe case of extra and intracranial abscesses due to S. constellatus in an immunocompetent host
ABSTRACT
ABSTRACT: This study examined the salivary pH, salivary lactate, and salivary IL-1 β responses from a high-intensity intermittent running test, and the influence of hygiene oral status on these biomarkers in elite adolescent basketball players. Forty-six adolescent players participated. Saliva sampling was taken before and 3 min after a high-intensity exercise (Yo-Yo Intermittent Recovery Test Level 1; Yo-Yo IR1). In order to quantify and classify the oral hygiene level, the athletes were submitted to a dental examination, and an adapted Simplified Oral Hygiene Index was applied. After the dental examination, the whole group was divided into good oral hygiene group (GHG) and poor oral hygiene group (PHG). The results of a two- way analysis of variance showed a significant interaction effect (P = 0.0003), group effect (P < 0.0001), and time effect (pre to post Yo-yo IR1; P < 0.0001) for salivary pH and for salivary lactate (interaction effect, P = 0.008; group effect, P < 0.000 1; time effect, P < 0.0001) with a lower salivary pH and a higher salivary lactate at pre and post-Yo-Yo IR1 for PHG, but no difference was observed for IL-1β. The data demonstrated that the high-intensity exercise led to a significant change in salivary pH and salivary lactate concentration of the basketball players, and that the oral hygiene status influenced these responses, with a greater change for those players showing a poor oral hygiene.
RESUMEN: Este estudio examinó las respuestas de pH salival, lactato salival e IL-1β salival de una prueba de carrera intermitente de alta intensidad, y la influencia del estado de higiene oral en los biomarcadores en jugadores adolescentes de baloncesto de élite. En el análisis participaron 46 jugadores adolescentes. Se tomó una muestra de saliva antes y 3 minutos después de un ejercicio de alta intensidad (Prueba de recuperación intermitente Yo-Yo Nivel 1; Yo-Yo IR1). Para cuantificar y clasificar el nivel de higiene oral, los atletas fueron sometidos a un examen dental y se aplicó un índice adaptado de higiene oral simplificado. Después del examen dental, el grupo se dividió en un grupo de buena higiene oral (GHG) y un grupo de mala higiene oral (PHG). Los resultados de un análisis de varianza mostraron un efecto de interacción significativo (P = 0.0003), efecto de grupo (P<0.0001) y efecto de tiempo (antes y después de Yo-yo IR1; P <0.0001) para el pH salival y para lactato salival (efecto de interacción, P = 0.008; efecto de grupo, P <0.0001; efecto de tiempo, P <0.0001) con pH salival más bajo y lactato salival más alto en IR1 pre y post YoY para PHG, pero no se observó una diferencia para IL-1β. Los datos demostraron que el ejercicio de alta intensidad genera un cambio significativo en el pH salival y el lactato de los jugadores de baloncesto, y que el estado de higiene oral influyó en estas respuestas, con un cambio mayor para aquellos jugadores que mostraron una mala higiene oral.

Resumen: Introducción: La boca del recién nacido se contamina inmediatamente con microorganismos maternos. Caufield determinó la colonización con SGM para niños americanos a los 26 meses de edad. Estudios latinoamericanos la ubican entre los 14,9-18 meses. Objetivos: -Identificar el momento de adquisición y colonización del SGM en una población de niños uruguayos y relacionarlo con factores del niño y maternos. Establecer el tiempo necesario para la recolección de la muestra y estudio de su pérdida. Método: Estudio observacional, longitudinal prospectivo, de 83 pares madre-hijo de un policlínico de Montevideo. De 83 pares examinados, 20 completaron el estudio. Se incluyeron niños de 0-9 meses, con/sin dientes y primera toma salival negativa para SGM. Resultados: Edad promedio de adquisición del SGM 16,4 meses (±4,13) y colonización 18,6 meses (±3,80) de edad. La pérdida de la muestra fue 71,42%. Conclusiones: La colonización resultó similar a la encontrada por Florio (Brasil), observándose diferencias significativas con Caufield (EEUU).

Abstract: Introduction: The newborn's mouth is immediately contaminated with maternal microorganisms at birth. Caufield determined that the average age of colonization with Mutants streptococci (MS) for American children was 26 months old. Latin American studies indicate that it occurs at an age between 14.9 and 18 months old. Objectives: To identify the time of MS acquisition and colonization in a population of Uruguayan children and to relate it with various child and maternal factors. To establish the time needed to collect the sample and its loss. Methods: Observational, longitudinal prospective study, of 83 mother-child pairs from a medical center in Montevideo. From the 83 pairs examined, 20 completed the study. Children between 0-9 months old, with/without teeth, whose first saliva sample was negative for MS, were included. Results: The mean age of MS acquisition was 16.4 months (± 4.13), and colonization occurred at 18.6 months (± 3.80) of age. The sample loss was 71.42%. Conclusions: The colonization found was similar to that found by Florio (Brazil) but showed significant differences with Caufield's results (USA).
ABSTRACT
Objective:To investigate the clinical efficacy of Gancao Xiexintang combined with vitamin B12 on recurrent oral ulcer (ROU) in children. Method:Totally 116 children with ROU admitted in Jiangxi Provincial Children's Hospital from June 2016 to June 2018 were divided into observation group and control group on the basis of random number table,with 58 cases in each group. The control group was orally treated with vitamin B12, while the observation group was orally treated with Gancao Xiexintang in addition to the therapy of the control group. All of the children were treated for 14 days. Clinical efficacy, changes of T lymphocyte subset (CD3+, CD4+, CD8+, CD4+/CD8+), ulcer area, content of oral flora (veillonella, streptococcus) before and after treatment, and side effect were compared between the two groups. Result:The overall effective rate of the observation group was 96.6%(56/58), which was much higher than 84.5%(49/58) of the control group (P+, CD4+, CD4+/CD8+in peripheral blood, but lower CD8+compared with those before treatment (P+, CD4+, CD8+, CD4+/CD8+) indexes in observation group was improved more significantly (PPPPPConclusion:In treating ROU in children, the combination of Gancao Xiexintang and vitamin B12 can significantly correct imbalance of T lymphocyte subset, promote the recovery of oral ulcer, and positively regulate oral micro-ecological environment, with an exact curative effect and high patient tolerance.
ABSTRACT
Objective To study the changes of oral flora in patients with diabetic ketoacidosis,in order to provide evidence for making oral nursing intervention and hygiene education. Methods 35 patients with diabetic ketoacidosis were named as group A,35 non-diabetic patients with chronic periodontitis (diagnostic criteria:periodontal pocket 14 mm) were named as group B,35 nonketotic patients with diabetes mellitus were named as group C,then all the patients were detected for the oral disease and the oral hygiene was evaluated. Results The gingival index,plaque index,tooth mobility,probing depth and hemorrhage after the detection of three groups had no significant differences. The detection rate of streptococcus oralis, lactobacillus,fusobacterium nucleatum,black-pigment bacteria,Capnocytophaga gingivalis,actinomycetes, escherichia coli,staphylococcus aureus and pseudomonas aeruginosa had no significant differences,there was a positive correlation between quantity of black-pigment bacteria, Capnocytophaga gingivalis and fasting blood glucose and glycosylated hemoglobin of patients with diabetic ketoacidosis. Conclusions Diabetic ketoacidosis strengthened the bacterial invasion and oral colonization of patients.

The most proper antibiotic must be selected after antimicrobial susceptibility test. If difference in antimicrobial susceptibility was significant between oral sampling sites, it is rationale to use the most susceptible antibiotic agent respond to dental procedure and object of treatment. This study examined sampling site variation from saliva, supragingival plaque and subgingival plaque of 16 children's oral microbes. The cultured bacterial isolates, which were Streptococcus viridans and Neisseria, were examined for 10 antimicribial drugs with the Bauer-Kirby agar disk diffusion method. The used drugs were Penicillin, Ampicillin, Oxacillin, Cephalothin, Imipenem, Gentamicin, Erythromycin, Vancomycin, Ciprofloxacin, Clindamycin. There was no significant difference between three sampling sites for antimicrobial susceptibility test of S. viridans and Neisseria and the sequence of susceptibility was agreed among them. In conclusion, it was suggested that antimicrobial susceptibility test from saliva, supragingival plaque and subgingival plaque of children have no significant sampling site variation.

The study determined the prevalence of Candida albicans in the mouth of 509 Filipino children (3 mo - 10 yrs) who did not show any detectable lesions. A sterile cotton swab was used to take materials from the mouth for mycological examination. Species of C. albicans was identified using the method of BakerspigelCandida organisms were isolated from 162 (31.8%) of the 509 children studied. C. albicans was the organisms isolated from 119 (21.4%) of these children. This finding presents a difficulty in making diagnosis of oral moniliasis. The appearance of characteristic lesions and the repeated isolation of C. albicans in large number are deemed necessary in the diagnosis of oral moniliasis
