RESUMEN
BACKGROUND Gas gangrene is a rapidly progressive and potentially fatal infection that is common in the extremities. Gas gangrene of the head and neck is a very rare condition, and non-clostridial gas-forming neck abscess caused by Klebsiella pneumoniae is unusual. This report is of a diabetic man with poor dental hygiene, a right dental abscess, and parapharyngeal abscess with gas gangrene due to Klebsiella pneumoniae infection, presenting with septic shock and multiorgan failure, who recovered after surgical neck debridement. CASE REPORT A 52-year-old man with diabetes mellitus lost consciousness and collapsed on a curbside. He presented with painful swelling of the right-side neck, associated with spiking fever, confusion, dyspnea, and stridor. He had right submandibular and supraclavicular swelling with crepitus, multiple dental caries, and multiorgan dysfunction, and was intubated. A computed tomography scan showed a gas-forming abscess in the right parapharyngeal, retropharyngeal, and paralaryngeal spaces and dense infiltration with pleural effusion in the upper lobes. Neck exploration was performed for drainage. Necrotic tissue and foul-smelling pus were debrided and drained. Gram stain showed gram-negative bacilli. Necrotic tissue, pus, and blood culture showed Klebsiella pneumoniae. He remained on intravenous meropenem for 14 days and was frequently debrided with irrigation until the infection subsided. Finally, normal physiologic functions of the failing organ system were restored. CONCLUSIONS We present a rare case of Klebsiella pneumoniae infection causing gas gangrene in the deep neck spaces, leading to septic shock and multiorgan failure, who recovered after surgical neck debridement. This is a potentially fatal condition that requires emergency drainage because of its high mortality rate.

OBJECTIVE: Although pneumonia is the leading cause of death among patients with dementia, the specific underlying causes remain unclear. In particular, the potential connection between pneumonia risk and dementia-related daily living difficulties, such as oral hygiene practice and mobility impairment, and the use of physical restraint as a management practice, has not been extensively studied. METHODS: In our retrospective study, we included 454 admissions corresponding to 336 individual patients with dementia who were admitted to a neuropsychiatric unit due to behavioral and psychological symptoms. The admissions were divided into two groups: those who developed pneumonia while hospitalized (n=62) and those who did not (n=392). We investigated differences between the two groups in terms of dementia etiology, dementia severity, physical conditions, medical complications, medication, dementia-related difficulties in daily living, and physical restraint. To control potential confounding variables, we used mixed effects logistic regression analysis to identify risk factors for pneumonia in this cohort. RESULTS: Our study found that the development of pneumonia in patients with dementia was associated with poor oral hygiene, dysphagia, and loss of consciousness. Physical restraint and mobility impairment showed a weaker, nonsignificant association with the development of pneumonia. CONCLUSIONS: Our findings suggest that pneumonia in this population may be caused by two primary factors: increased pathogenic microorganisms in the oral cavity due to poor hygiene, and an inability to clear aspirated contents due to dysphagia and loss of consciousness. Further investigation is needed to clarify the relationship between physical restraint, mobility impairment, and pneumonia in this population.

BACKGROUND: Streptococcus cristatus is a member of the Mitis streptococcus group. Like other members of this group, it resides on mucosal surfaces of the oral cavity. However, little is known about its ability to cause disease as there are only a handful of cases in the literature. Two of these cases involved infective endocarditis with significant complications. However, these cases involved additional microbes, limiting the inferences about the pathogenicity of Streptococcus cristatus. CASE PRESENTATION: A 59-year-old African American male with end-stage cryptogenic cirrhosis and ascites presented with fatigue and confusion. A paracentesis was negative for spontaneous bacterial peritonitis, but two separate blood cultures grew Streptococcus cristatus. Our patient had a history of dental caries and poor oral hygiene, which were likely the source of the infection. Echocardiograms revealed new aortic regurgitation, indicating "possible endocarditis" per the Modified Duke Criteria. However, since his clinical picture and cardiac function were reassuring, we elected against treatment for infective endocarditis. He was treated for bacteremia with a 2-week course of cephalosporins consisting of 8 days of ceftriaxone, transitioning to cefpodoxime after discharge. Despite having end-stage liver disease, our patient did not experience any significant complications from the infection. CONCLUSION: A patient with end-stage cirrhosis and poor oral hygiene developed bacteremia with an oral bacterium called Streptococcus cristatus. Unlike previous cases in literature, our patient did not meet criteria for a definitive diagnosis of infective endocarditis, and he experienced no other complications from the infection. This suggests coinfectants may have been primarily responsible for the severe cardiac sequelae in prior cases, whereas isolated Streptococcus cristatus infection may be relatively mild.

BACKGROUND: Infective endocarditis (IE) is characterized by low incidence but high mortality. Patients with a history of IE are at highest risk. Adherence to prophylaxis recommendations is poor. We sought to identify determinants of adherence to oral hygiene guidelines on IE prophylaxis in patients with a history of IE. METHODS: Using data from the cross-sectional, single-centre POST-IMAGE study, we analysed demographic, medical and psychosocial factors. We defined patients as adherent to prophylaxis if they declared going to the dentist at least annually and brushing their teeth at least twice a day. Depression, cognitive status and quality of life were assessed using validated scales. RESULTS: Of 100 patients enrolled, 98 completed the self-questionnaires. Among these, 40 (40.8%) were categorized as adherent to prophylaxis guidelines, and were less likely to be smokers (5.1% vs. 25.0%; P=0.02) or have symptoms of depression (36.6% vs. 70.8%; P<0.01) or cognitive decline (0% vs. 15.5%; P=0.05). Conversely, they had higher rates of: valvular surgery since the index IE episode (17.5% vs. 3.4%; P=0.04), searching for information on IE (61.1% vs. 46.3%, P=0.05), and considering themselves as adherent to IE prophylaxis (58.3% vs. 32.1%; P=0.03). Tooth brushing, dental visits and antibiotic prophylaxis were correctly identified as measures to prevent IE recurrence in 87.7%, 90.8% and 92.8% of patients, respectively, and did not differ according to adherence to oral hygiene guidelines. CONCLUSIONS: Self-reported adherence to secondary oral hygiene guidelines on IE prophylaxis is low. Adherence is unrelated to most patient characteristics, but to depression and cognitive impairment. Poor adherence appears related more to a lack of implementation rather than insufficient knowledge. Assessment of depression may be considered in patients with IE.

BACKGROUND: Dental erosion is an irreversible condition of loss of teeth hard tissues caused by intrinsic or extrinsic acids attack, without bacterial involvement. Common soft drinks have an acid pH and they release hydrogen ions and act as chelating agents, dissolving teeth mineral component. The aim of the study was to investigate the correlation between the consumption of soft drinks in children and the degree of dental erosion. METHODS: A questionnaire of 15 multiple choice questions was addressed to the parents of the 231 children needing different dental treatments. Responses were compared with the level of dental erosion of their child, that was clinically investigated using the Basic Erosive Wear Examination (BEWE) index. RESULTS: About 26.8% of subjects fall into a high-risk category of dental erosion while 24.2% in a low risk level. Socioeconomic status and oral hygiene habits are able to affect the degree of dental erosion. Toothpastes containing fluoride have not proved effective in preventing this phenomenon and no significant correlations were found between the type of toothbrush used and its frequency of use. CONCLUSIONS: It is necessary to apply preventive measures such as information on the processes and causes of erosion, instruction about right home oral hygiene maneuvers and the possible use of specific products, to avoid the development of problems related to severe dental wear.

This systematic review aimed to investigate the risk predictors of caries in primary teeth and evaluate their association with the increment of Early Childhood Caries (ECC) among preschool children. This systematic review included only cohort or case-control studies of at least 2 years duration, over 300 participants and with English full-text. Potentially eligible studies were retrieved from 4 electronic databases (Ovid Embase, Ovid MEDLINE; PubMed, Web of Science) from inception to March 1, 2021. Independent screening and data extraction by 2 reviewers to identify factors associated with ECC increment, including family and socioeconomic factors, dietary and oral health-related habits, and clinical parameters. A total of 18 studies from 163 potential reports were included, involving 1,159,226 preschool children. Lower parental education attainment was found associated with ECC increment (WMD:0.87; 95% CI 0.52, 1.21); whereas immigration status (WMD:-0.38; 95% CI -1.09, 0.34), gender (WMD:-0.02; 95% CI -0.28, 0.24), and dental service utilization (WMD:0.35; 95% CI -0.10, 0.79) were not significant factors for ECC increment. All included studies consistently suggested positive correlations between ECC increment and baseline caries experience, plaque level, cariogenic microorganisms, and prenatal and passive smoking, while mixed findings were detected between ECC increment with dietary and oral hygiene practices. Preschool children whose parents have low education level are more likely to have greater increment of ECC over 2 years. Existing caries lesions, increased dental plaque level, cariogenic microorganisms, prenatal or passive smoking were also consistently identified as risk factors for ECC in all reviewed studies. This systematic review highlights specific risk factors to target for the prevention of ECC and supports implementing more oral health promotion for preschool children with parents of lower educational attainment.

Ventilator-associated pneumonia (VAP) is related with high mortality, duration of mechanical ventilation and costs. Recent studies have questioned the safety and effectiveness of oral chlorhexidine to prevent VAP. We sought to verify whether the adverse effects of this substance outweigh its benefits. We searched several databases and selected studies that investigated the use of oral chlorhexidine and its impact on mortality. No association between oral chlorhexidine and lower VAP rates was found on meta-analyses of double-blind randomized trials, however significant increase in mortality was reported. It is speculated that chlorhexidine can cause damage to several organic sectors and cytotoxicity. Although it still can be beneficial in specific settings, robust evidence to recommend its routine application for all mechanically ventilated patients is lacking; therefore, given the possibility of harm, it would be better to follow the principle of non-maleficence until more studies becomes available.

Introduction: Brackground: in the early stages of kidney disease, oral manifestations (gingivitis and periodontitis) may cause premature tooth loss and limit food intake. There is scarce evidence of the relationship of oral hygiene and nutritional status in patients on Peritoneal Dialysis (PD). Objective: we aimed to assess the relationship of oral hygiene with nutritional, clinical, and physical performance parameters in PD patients. Methods: this cross-sectional study included outpatients aged 34-69 years. Oral health questionnaire, nutritional, functional, and clinical assessment tools such as Malnutrition Inflammation Score (MIS), Subjective Global Assessment (SGA), handgrip strength, and Gastrointestinal Symptoms Questionnaire (GSQ) were applied. Patients were divided according to debris, calculus, and Simplified Oral Hygiene Index (OHI-S) in two groups: "clean-slightly dirty" and "dirty-very dirty". Results: in total, 41 patients were included, those in the "dirty-very dirty" group had a worse nutritional status with higher scores on the MIS tool and worse nutritional diagnosis with SGA as compared to the "clean-slightly dirty" group. The handgrip strength was higher in patients in the best category of oral hygiene, and those with the worst hygiene presented greater severity of gastrointestinal symptoms. The risks of malnutrition in the three indices of oral hygiene with the worst category were statistically significant. Conclusion: poor oral hygiene was associated with poorer nutritional status, lower handgrip, and worse GSQ. Poor oral hygiene might be related to persistent inflammation status and catabolism that favored protein-energy wasting.
Introducción: Introducción: en las primeras etapas de la enfermedad renal, las manifestaciones orales (gingivitis y periodontitis) pueden causar la pérdida de dientes prematura y limitar la ingestión de los alimentos. Existe poca evidencia de la relación entre la higiene bucal y el estado de nutrición en los pacientes con Diálisis Peritoneal (PD). Objetivos: evaluar la relación de la higiene bucal con los parámetros nutricionales, clínicos y de funcionalidad física en pacientes con DP. Métodos: este es un estudio transversal que incluyó a pacientes ambulatorios de 34 a 69 años. Se aplicó un cuestionario de salud bucal, herramientas de evaluación nutricional, pruebas de funcionalidad y un cuestionario de síntomas gastrointestinales, con las herramientas MIS (Malnutrition Inflammation Score), SGA (Subjective Global Assessment); fuerza de prensión de mano y el cuestionario de síntomas gastrointestinales GSQ (Gastrointestinal Score Questionnaire). Los pacientes fueron agrupados de acuerdo con los índices de placa, cálculo y OHI-S (Simplified Oral Hygiene Index) en dos grupos: "limpio-ligeramente sucio" y "sucio-muy sucio". Resultados: se incluyeron 41 pacientes en total, aquellos en el grupo "sucio-muy sucio" presentaron un peor estado nutricional con mayores puntajes de la herramienta MIS y peor diagnóstico nutricional con la SGA comparado con el grupo "limpio-ligeramente sucio". La fuerza de prensión de mano fue mayor en los pacientes con la mejor categoría de higiene bucal, y aquellos con peor higiene presentaron mayor gravedad de síntomas gastrointestinales. El riesgo de desnutrición en los tres índices de higiene bucal con la peor categoría fueron estadísticamente significativos. Conclusiones: la mala higiene bucal se asoció con un peor estado nutricional, menor fuerza de prensión de la mano y peor GSQ. Una higiene bucal deficiente podría estar relacionada con un estado de inflamación y catabolismo persistentes favoreciendo el desgaste proteínico energético en pacientes en diálisis peritoneal.

OBJECTIVE: Coloring dental biofilm and plaque with a dental disclosing solution is visually effective in dental treatment and oral hygiene education. Despite continuous reports of the risk of the product ingredients, dental disclosing solution are widely used in dentistry. However, the cytotoxic mechanism of dental disclosing solution is not known. Here we elucidated the tissue dyeing range and investigated the cytotoxic mechanism of dental disclosing solution. MATERIALS AND METHODS: Gingival epithelial cells and mouse head and neck tissue were stained with dental disclosing solution. Changes in the cell cycle distribution by the dental disclosing solution treatment were analyzed. A deoxynucleotidyl transferase dUTP nick and labeling (TUNEL) assay was performed to examine the apoptotic features of the gingival epithelial cells. RESULTS: Dental disclosing solution stained the chromosome strongly, as well as both the hard and soft tissue of the mouse head and neck. The results of flow cytometric analysis and TUNEL analyses revealed that the cytotoxicity associated with dental disclosing solution was related to the induction of apoptosis. However, the staining of porcine skin by dental disclosing solution was not easily removed, even with a wide range of pH solutions. CONCLUSIONS: These results suggest that dental disclosing solution had strong cytotoxicity and safer alternatives are needed.

Dental diseases are among the common health issues experienced around the world. Dental caries is one of the most predominant oral diseases worldwide. Major factors associated with caries development include poor oral hygiene, the content of specific carbohydrates in the diet, dental biofilm formation, the cariogenic microbial load, reduction in salivary flow, insufficient fluoride exposure, gingival recession, genetic factors, and lack of personal attention to one's dental health. Several preventive measures have been implemented to reduce the risk of the development of caries. Probiotics are live microbes that when administered in suitable amounts confer health benefits on the host; they are recognized as potential adjunct therapeutic agents for several diseases. The present manuscript summarizes recent findings on the role of probiotics in dental caries prevention and the possible mechanisms of probiotic effects. Review of the literature indicates the regular consumption of probiotic products significantly reduced the risk of caries by inhibiting cariogenic bacteria and enriching commensal microbes in the oral cavity. Buffering the salivary pH, production of bacteriocin and enzymes (dextranase, mutanase, and urease), the capacity of competing for the adhesion and colonization on tooth surfaces are the possible mechanisms behind the beneficial effect of probiotics. Further studies are necessary to address the efficacy of long-term probiotic supplementation on the control of dental diseases and the influence of childhood probiotic supplementation on the risk of caries development.

Background and Objectives: Masticatory limitations on the dietary habits of edentulous subjects restrict their access to adequate nutrition, exposing them to a greater risk of protein energy malnutrition. The aim of this study is to verify the existence of an association between Masticatory Performance (MP) and nutritional changes in the elderly. Materials and Methods: 76 participants were enrolled. MP testing was performed using the two-color chewing gum mixing test. The system used reveals the extent to which the two differently colored chewing gums mix, and allows discrimination between different MPs. The assessment of the participants' nutritional statuses was carried out through a food interview. Anthropometric parameters were collected, and bioimpedance analysis was performed. Results: Mean MP was 0.448 ± 0.188. No statistically significant differences were detected between male and female subjects (p > 0.05). According to the Body Mass Index (BMI), obese patients had a lower MP than overweight and normal weight subjects (0.408 ± 0.225, 0.453 ± 0.169 and 0.486 ± 0.181, respectively). MP values were lower both in male and female subjects with a waist circumference above the threshold than those below it (0.455 ± 0.205 vs. 0.476 ± 0.110, respectively, in males and 0.447 ± 0.171 vs. 0.501 ± 0.138, respectively, in females). No relationship was noticed between MP and bioimpedance parameters (p > 0.05). Conclusions: A statistically significant relation was observed between MP and the number of missing teeth. A reduced MP could worsen nutritional parameters. A reduced MP did not seem to negatively affect bioimpedance parameters.

OBJECTIVE: There is a relationship between RA and periodontal disease. We aimed to investigate if a good oral hygiene could improve activity of RA. METHODS: The patients with RA according to ACR/EULAR 2010 criteria and included in the French early arthritis ESPOIR cohort were included in a randomized nested study into: (i) intervention group: general recommendations of good oral hygiene including teeth brushing, daily antiseptic mouthwash and twice a year scaling; and (ii) control group: no intervention. The primary end point was the delta DAS28-ESR. RESULTS: Four hundred and seventy-two patients were randomized (238 in intervention and 234 in control). 92/238 from the intervention group accepted the procedure and 81 had a first visit to the dentist. 56% of patients had periodontal disease at baseline. Duration of RA was 9.0±0.7 years. Baseline DAS28-ESR was 2.7±1.3. After a median duration of 24 months, delta DAS28-ESR was -0.17±1.29 and -0.09±1.28 in intervention and control groups, respectively (mean difference (complier average causal effect): -0.37 (95% CI -1.12, 0.37), P = 0.33). In the intervention group, there was a significant decrease of the bacteria involved in the red complex: Porphyromonas gingivalis (P = 0.002), Tannerella forsythia (P = 0.002) and Treponema denticola (P = 0.019). The patients with baseline periodontal disease and those who became negative for one red complex bacterium had a slightly more important decrease of DAS28-ESR. CONCLUSION: Oral hygiene instruction together with regular scaling and polishing of the teeth significantly decreased the load of periodontal pathogens but did not decrease RA activity. This intervention should be tested in patients with earlier RA and more active disease. TRIAL REGISTRATION: ClinicalTrials.gov, http://clinicaltrials.gov, NCT01831648.

BACKGROUND: Routine application of chlorhexidine oral rinse is recommended to reduce risk of ventilator-associated pneumonia (VAP) in mechanically ventilated patients. Recent reappraisal of the evidence from two meta-analyses suggests chlorhexidine may cause excess mortality in non-cardiac surgery patients and does not reduce VAP. Mechanisms for possible excess mortality are unclear. The CHORAL study will evaluate the impact of de-adopting chlorhexidine and implementing an oral care bundle (excluding chlorhexidine) on mortality, infection-related ventilator-associated complications (IVACs), and oral health status. METHODS: The CHORAL study is a stepped wedge, cluster randomized controlled trial in six academic intensive care units (ICUs) in Toronto, Canada. Clusters (ICU) will be randomly allocated to six sequential steps over a 14-month period to de-adopt oral chlorhexidine and implement a standardized oral care bundle (oral assessment, tooth brushing, moisturization, and secretion removal). On study commencement, all clusters begin with a control period in which the standard of care is oral chlorhexidine. Clusters then begin crossover from control to intervention every 2 months according to the randomization schedule. Participants include all mechanically ventilated adults eligible to receive the standardized oral care bundle. The primary outcome is ICU mortality; secondary outcomes are IVACs and oral health status. We will determine demographics, antibiotic usage, mortality, and IVAC rates from a validated local ICU clinical registry. With six clusters and 50 ventilated patients on average each month per cluster, we estimate that 4200 patients provide 80% power after accounting for intracluster correlation to detect an absolute reduction in mortality of 5.5%. We will analyze our primary outcome of mortality using a generalized linear mixed model adjusting for time to account for secular trends. We will conduct a process evaluation to determine intervention fidelity and to inform interpretation of the trial results. DISCUSSION: The CHORAL study will inform understanding of the effectiveness of de-adoption of oral chlorhexidine and implementation of a standardized oral care bundle for decreasing ICU mortality and IVAC rates while improving oral health status. Our process evaluation will inform clinicians and decision makers about intervention delivery to support future de-adoption if justified by trial results.

Poor oral hygiene is an established risk factor of head and neck cancer (HNC); however, its role in the survival of HNC patients is unclear. This study evaluated the association between oral hygiene habits, including regular dental visits, frequency of tooth brushing, and use of dental floss, and the overall survival (OS) of HNC patients using interview data collected from 740 HNC patients. In addition, the interactions between oral hygiene and the polymorphisms of TLR2 and TLR4 on the OS of HNC patients were assessed. The analysis indicated that poor oral hygiene was significantly associated with poorer OS of HNC patients (hazard ratio (HR) = 1.38, 95% confidence interval (CI): 1.03-1.86). This association was modified by a single nucleotide polymorphism, rs11536889, of TLR4. A significant association between poor oral hygiene and worse survival of HNC was observed among those with the CG or CC genotype (HR = 2.32, 95% CI: 1.41-3.82) but not among those with the GG genotype (HR = 0.95, 95% CI: 0.65-1.40). Our results suggested that poor oral hygiene is not only a risk factor but may also be a prognostic factor of HNC.

OBJECTIVE: Postoperative pneumonia is one of the most common complications after cardiac surgery, entailing increased patient morbidity, mortality, and health care burden. The primary aim of this study was to assess whether preoperative chlorhexidine mouthwash is associated with reduced postoperative pneumonia after cardiac surgery. METHODS: A comprehensive systematic search of NLM Pubmed, Embase, Scopus, and Cumulative Index of Nursing and Allied Health was executed to include the studies since inception to June 27, 2017, which assessed the effects of preoperative chlorhexidine gluconate mouthwash on postoperative pneumonia. Studies were identified by 2 independent reviewers, and data were extracted using a predefined protocol. Random effects models were run to obtain risk ratios with 95% confidence intervals. Quality of evidence was evaluated using Grading of Recommendations Assessment, Development and Evaluation criteria. Postoperative pneumonia after cardiac surgery was the primary outcome of the study. RESULTS: Five studies including a cumulative of 2284 patients were included. A total of 1125 patients received preoperative chlorhexidine. Use of chlorhexidine gluconate was associated with reduced risk of postoperative pneumonia compared with the patients who did not receive it (risk ratio, 0.52; 95% confidence interval, 0.39-0.70; P < .001). No adverse effects from chlorhexidine gluconate mouthwash were reported by any of these studies. CONCLUSIONS: Among the patients receiving preoperative chlorhexidine mouthwash, the risk of postoperative pneumonia is reduced by approximately one-half; its adoption in preoperative protocols could help improve patient outcomes.

An odontogenic cause of a lung abscess is often overlooked. A 61-year-old man presented at an emergency department with a productive cough and dyspnoea. He was admitted to the pulmonary ward with a suspected odontogenic lung abscess. A thorax CT scan confirmed the diagnosis 'lung abscess', following which an oral-maxillofacial surgeon confirmed that the lung abscess probably had an odontogenic cause. The patient made a full recovery following a 6-week course of antibiotics, and his teeth were remediated by means of full extraction and the fabrication of immediate dentures. Poor oral hygiene can be a cause of a lung abscess. A patient with a lung abscess can be treated successfully with antibiotics. If, however, the odontogenic cause is not recognised the abscess can recur.

BACKGROUND: Given the importance of inflammation as a predictor of poor outcomes in End Stage Renal Disease (ESRD), reductions in inflammatory biomarkers have been proposed as a critical target in this population. This study targets chronic periodontitis, an oral inflammatory disease of microbial etiology causing persistent inflammation in ESRD. Unlike the previously reported episodic periodontal interventions, we propose to control periodontal inflammation with a continuous maintenance and oral health behavior modifications. We hypothesize that this strategy will improve systemic inflammation and oxidative stress, oral health and quality of life within the 6-month observation period. METHODS: The rePAIR (novel PAradigm to improve Inflammatory burden in ESRD) study is a pilot and feasibility, parallel-arm, and randomized controlled clinical trial that will recruit 72 ESRD subjects with periodontitis in a model of computerized block randomization. This trial aims to compare the effect of standard-of-care vs. repeated non-surgical periodontal therapy on systemic and oral inflammatory burden. This trial will recruit ESRD adult patients with periodontitis older than 21 years old with a minimum of 12 teeth and no history of periodontal treatment within a year. The trial will examine serum C-reactive protein (CRP) (primary outcome) as a biomarker of inflammation as well as interleukin-6 (IL-6), F2 isofurans and F2 isoprostanes (secondary outcomes) and compare their difference between groups from baseline to 6 months. The trial will also compare the difference between groups in patient-centered and clinical oral outcomes from baseline to 6 months. DISCUSSION: The trial follows a rigorous and transparent study design capturing elements such as pre-specified eligibility criteria, pre-specified primary and secondary outcomes, detailed intervention description to allow replication, intervention random allocation and concealment, blinding in outcome assessment, appropriate sample size calculations, explanation of interim analysis, as per CONSORT Guidelines. Further, gender diversity is secured not only at recruitment but also throughout the trial and during the analysis. Therefore, treatment response outcomes will be examined per gender category. In order to manage anticipated problems, the protocol has included alternative approaches. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03241511 . Registered on 7 August 2017.

BACKGROUND: The oral cavity is a potential reservoir for respiratory pathogens. This longitudinal study investigated the association between upper respiratory tract infection (URI) and oral health among children. METHODS: A total of 288 children aged 4 years were recruited. Their dental caries and oral hygiene status were clinically determined, using the dmft (decayed, missing and filled teeth) index and the Silness-Löe plaque index. Questionnaires were completed by parents to collect information on the child's socio-demographic background and URI episodes and symptoms in the following 12 months. Standard or zero-inflated negative binomial regressions were used to analyse the association between URI and both oral health indicators (dmft and plaque score). RESULTS: Some 138 (47.9%) children had URI in 12 months, including 63 (21.9%) and 75 (26.0%) children with 1-2 episodes and ≥3 episodes, respectively. The reported URI episodes fell into two peaks, coinciding with the two influenza peaks in Hong Kong. Significantly a higher dmft was found among children without URI compared with children who had ≥3 URI episodes (1.32 vs. 0.49; P = 0.043). The number of URI episodes was inversely associated with dmft (IRR = 0.851; 95% CI: 0.766-0.945; P = 0.003). There was no significant association between the plaque score and URI (P > 0.05). CONCLUSIONS: The children's caries experience was associated with reduced episodes of URI. Whether this inverse association is attributed to the immune response induced by dental caries is yet to be investigated.

Infective endocarditis (IE) is associated with significant morbidity and mortality. The prevention of infective endocarditis, for many years, has involved the identification of at risk patients undergoing medical or dental procedures and the use of pre-procedural antibiotic prophylaxis. However, evidence regarding the effectiveness of such measures is lacking while evidence is mounting for the adverse effects of inappropriate antibiotic use. International guidelines for antibiotic prophylaxis were amended, radically in some cases to reflect this. Subsequent epidemiological observations of IE have shown mixed results, strengthening calls for well conducted randomised control trials, now that there is genuine clinical equipoise among clinicians about this question.
