Zhang Q, Huang H, Li J, Niu Y, Sun P, Cheng F. Knowledge, attitudes and practices of patients with chronic pharyngitis toward laryngopharyngeal reflux in Suzhou, China. BMC Public Health 2023; 23:2542. [PMID: 38115020 PMCID: PMC10731724 DOI: 10.1186/s12889-023-17463-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 12/12/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND This study aimed to investigate the knowledge, attitudes and practices (KAP) of patients with chronic pharyngitis in Suzhou, China toward laryngopharyngeal reflux (LPR). METHODS This cross-sectional study was conducted in patients with chronic pharyngitis in Suzhou, China at the otolaryngology outpatient clinic of the First Affiliated Hospital of Soochow University between November, 2022, and May, 2023. Data was collected through a self-designed online questionnaire encompassing the sociodemographic characteristics and three dimensions of KAP. The questionnaire was administered using SoJump, and data were exported from this platform. Subsequently, statistical analysis, including Structural Equation Modeling, was performed using SPSS 22 software to evaluate the KAP scores. RESULTS A total of 487 valid questionnaires were collected, with 275 (56.35%) female patients. The mean score of KAP were 4.76 ± 2.93 (possible range: 0-11), 33.10 ± 4.46 (possible range: 8-40), 31.29 ± 6.04 (possible range: 8-40), respectively. Pearson's correlation analysis showed significant positive correlations between knowledge and attitude dimensions (r = 0.413, P < 0.001), knowledge and practice dimensions (r = 0.355, P < 0.001), and attitude and practice dimensions (r = 0.481, P < 0.001). Structural equation modeling revealed that education exhibited positive effect on knowledge (β = 0.476, P < 0.001) and attitude (β = 0.600, P < 0.001), and having family history of chronic pharyngitis showed positive effect on knowledge (β = 0.580, P = 0.047), experienced with reflux symptoms showed positive effect on knowledge (β = 0.838, P = 0.001) and attitude (β = 0.631, P = 0.085). Moreover, knowledge showed positive effect on attitude (β = 0.555, P < 0.001) and practice (β = 0.351, P < 0.001). Attitude, in turn, showed positive effect on practice (β = 0.511, P < 0.001). CONCLUSION Patients with chronic pharyngitis had inadequate knowledge, positive attitudes and suboptimal practices toward LPR. Education, family history of chronic pharyngitis, experienced with reflux symptoms might have effect on their KAP.

Rabdosichuanin C inhibits productions of pro-inflammatory mediators regulated by NF-κB signaling in LPS-stimulated RAW264.7 cells. J Cell Biochem 2023; 124:1667-1684. [PMID: 37850620 DOI: 10.1002/jcb.30474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 06/14/2023] [Accepted: 08/26/2023] [Indexed: 10/19/2023]
Abstract
Chronic pharyngitis (CP) is an inflammatory disease of the pharyngeal mucosa and its lymphatic tissues that is difficult to treat clinically. However, research on the exact therapeutic agents and molecular mechanisms of CP is still unclear. In this study, we investigated Rabdosichuanin C (RC) to attenuate lipopolysaccharide (LPS)-induced inflammatory damage in RAW264.7 cells by a combination of targeted virtual screening and in vitro activity assay and further clarified its molecular mechanism of action centering on the IκB/nuclear factor kappa B (NF-κB) pathway. Molecular docking and pharmacophore simulation methods were used to screen compounds with IκB inhibitory effects. Expression of genes and proteins related to the IκB/NF-κB signaling pathway by RC in LPS-induced inflammatory injury model of RAW264.7 cells was detected by PCR, enzyme-linked immunosorbent assay, and Western blot. The docking of RC with IκB protein showed good binding energy, and pharmacophore simulations further confirmed the active effect of RC in inhibiting IκB protein. RC intervention in LPS-induced RAW264.7 cells significantly reduced the expression levels of inflammatory factors tumor necrosis factor-α, interleukins-6, iNOS, and CD-86 at the messenger RNA and protein levels, downregulated IκB, p65 protein phosphorylation levels, and significantly inhibited IκB/NF-κB signaling pathway activation. Virtual screening provided us with an effective method to rapidly identify compounds RC that target inhibit the action of IκB, and the activity results showed that RC inhibits NF-κB signaling pathway activation. It is suggested that RC may play a role in the treatment of CP by inhibiting the IκB/NF-κB signaling pathway.

INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2023:105453. [PMID: 37245779 DOI: 10.1016/j.meegid.2023.105453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 05/05/2023] [Accepted: 05/23/2023] [Indexed: 05/30/2023]
Abstract
Aboriginal and Torres Strait Islander People (respectfully referred to as Indigenous Australians herein) are disparately burdened by many infectious and chronic diseases relative to Australians with European genetic ancestry. Some of these diseases are described in other populations to be influenced by the inherited profile of complement genes. These include complement factor B, H, I and complement factor H-related (CFHR) genes that can contribute to a polygenic complotype. Here the focus is on the combined deletion of CFHR1 and 3 to form a common haplotype (CFHR3-1Δ). The prevalence of CFHR3-1Δ is high in people with Nigerian and African American genetic ancestry and correlates to a higher frequency and severity of systemic lupus erythematosus (SLE) but a lower prevalence of age-related macular degeneration (AMD) and IgA-nephropathy (IgAN). This pattern of disease is similarly observed among Indigenous Australian communities. Additionally, the CFHR3-1Δ complotype is also associated with increased susceptibility to infection with pathogens, such as Neisseria meningitidis and Streptococcus pyogenes, which also have high incidences in Indigenous Australian communities. The prevalence of these diseases, while likely influenced by social, political, environmental and biological factors, including variants in other components of the complement system, may also be suggestive of the CFHR3-1Δ haplotype in Indigenous Australians. These data highlight a need to define the Indigenous Australian complotypes, which may lead to the discovery of new risk factors for common diseases and progress towards precision medicines for treating complement-associated diseases in Indigenous and non-Indigenous populations. Herein, the disease profiles suggestive of a common complement CFHR3-1Δ control haplotype are examined.

Abstract
The relevance of the problem of chronic inflammatory diseases of the pharynx is due to the significant prevalence of this pathology. Among all forms of chronic pharyngitis, the most adverse effect on the quality of life is observed in chronic athrophic pharyngitis. According to the literature, in this category of patients there are no clear criteria for assessing the functional state and morphological picture of the mucous membrane of the posterior pharyngeal wall. Most of the described signs of atrophic pharyngitis are insufficienyly informative, which necessitates further improvement of existing and possible search for new diagnostic methods. Many of the modern methods of treatment do not provide a lasting effect due to the presence of only a local effect on the altered mucous membrane of the posterior pharyngeal wall, without taking into account the changes that are caused by a violation of trophic processes in the tissue, which necessitates the search for new effective methods of treating this disease.The review article outlines modern ideas about the methods of diagnosis and treatment of chronic pharyngitis, presents promising areas in the treatment of patients with atrophic pharyngitis. In foreign countries, the term «chronic tonsillopharyngitis» is most often used. Due to the existing difference in terminology, the predominant part of the material on the problem of chronic pharyngitis is presented by domestic literature sources.

Biomed Pharmacother 2021; 140:111787. [PMID: 34091181 DOI: 10.1016/j.biopha.2021.111787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Revised: 04/27/2021] [Accepted: 05/25/2021] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE Explore the effects of high-temperature reflux extraction and low-temperature decompressing inner ebullition on Triphala's chemical composition and anti-chronic pharyngitis activity. METHODS The network pharmacology was used to analyze the material basis, targets and pathways of Triphala for chronic pharyngitis. HPLC were used to compare the fingerprint profile and content of components between the two extracts. The antioxidant and anti-chronic pharyngitis activities of the two extracts were compared by DPPH assay and ammonia induced chronic pharyngitis model in rats. RESULTS The network pharmacology results showed that the active ingredients of Triphala for chronic pharyngitis are epigallocatechin-3-gallate, (+)-catechin, epicatechin, epicatechin gallate, (+)-gallocatechin, quercetin, luteolin, leucodelphinidin and other flavonoids; phenolic acids such as gallic acid and ellagic acid; alkaloids such as ellipticine, cheilanthifoline; hydrolyzed tannins such as corilagin and chebulic acid. The high-temperature reflux extract and the low-temperature decompressing inner ebullition extract have extremely significant differences in the fingerprint profile. Among them, the content of gallic acid, ellagic acid, chebulic acid, catechin, epicatechin, corilagin, quercetin, and epicatechin gallate in the reflux extract is 1.1-5.3 times as much as decompressing inner ebullition extract. The free radical scavenging ability of reflux extract is significantly stronger than that of decompression extract (p < 0.01), and it has a repairing effect on pharyngeal mucosal damage (reducing keratinization or hyperplasia of mucosal epithelium, reducing inflammatory cell infiltration and bleeding), and reducing IL-1β (P<0.05), IL-6 (p<0.05), TNF-α overexpression ability is stronger than the decompressing inner ebullition extract. CONCLUSIONS gallic acid, ellagic acid, chebulic acid, catechin, epicatechin, corilagin and epicatechin gallate are the basic aglycones or oligomers of tannin. High temperature reflux extraction can significantly promote the occurrence of the hydrolysis of tannins and significantly increases the content of these components.Therefore, its anti-chronic pharyngitis activity is enhanced. It is suggested that high temperature reflux extraction should be used in the treatment of chronic pharyngitis.

Abstract
Recently discovered preventive effects of probiotics on oral health have attracted interest to their use for the prevention and treatment of various diseases. This study aimed to evaluate the antimicrobial and antibiofilm properties of Weissella cibaria against Streptococcus pyogenes, Staphylococcus aureus, S. pneumoniae, and Moraxella catarrhalis, the major pathogens of upper respiratory tract infections (URTIs). The antimicrobial activities of W. cibaria were compared with those of other oral probiotics using a competitive inhibition assay and the determination of the minimum inhibitory concentrations (MICs). In addition, a time-kill assay, spectrophotometry, and confocal laser scanning microscopy were used to confirm the antimicrobial and antibiofilm abilities of W. cibaria CMU (oraCMU) and CMS1 (oraCMS1). Both live cells and cell-free supernatants of all tested probiotics, except Streptococcus salivarius, showed excellent antimicrobial activities. All target pathogens were killed within 4 to 24 h at twice the MIC of oraCMU and oraCMS1, which showed the highest antimicrobial activities against M. catarrhalis. The antimicrobial substances that affected different target pathogens were different. Both oraCMU and oraCMS1 showed excellent abilities to inhibit biofilm formation and remove preformed biofilms. Our results suggest that the W. cibaria probiotics offer new possibilities for the prevention and treatment of bacterial URTIs.

Abstract
Laryngopharyngeal reflux (LPR) is a common disease in the general population with acute or chronic symptoms. LPR is often misdiagnosed in primary care because of the lack of typical gastroesophageal reflux disease (GERD) symptoms and findings on endoscopy. Depending on the physician's specialty and experience, LPR may be over- or under-diagnosed. Management of LPR is potentially entirely feasible in primary care as long as General Practitioners (GPs) are aware of certain "red flags" that will prompt referral to a Gastroenterologist or an Otolaryngologist. The use of patient-reported outcome questionnaires and the consideration of some easy ways to diagnose LPR without special instrumentation oropharyngeal findings may help the GP to diagnose and often manage LPR. In this review, we provide a practical algorithm for LPR management for GPs and other specialists that cannot perform fiberoptic examination. In this algorithm, physicians have to exclude some confounding conditions such as allergy or other causes of pharyngolaryngitis and "red flags". They may prescribe an empirical treatment based on diet and behavioral changes with or without medication, depending on the symptom severity. Proton pump inhibitors and alginates remain a popular choice in order to protect the upper aerodigestive tract mucosa from acid, weakly acid and alkaline pharyngeal reflux events.

INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2020; 64:1923-1931. [PMID: 32780156 DOI: 10.1007/s00484-020-01980-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/19/2020] [Accepted: 07/28/2020] [Indexed: 06/11/2023]
Abstract
We present results on a time-series study that analyzed the acute effects of six criteria air pollutants on hospital outpatient with chronic pharyngitis (CP) in Xinxiang, China. Data on the concentration of air pollutants and CP outpatient records were collected daily in Xinxiang, China, from January 1, 2015 to December 31, 2018. This study identified 62,823 outpatients with CP. The annual average concentrations of PM2.5, PM10, SO2, NO2, CO, and O3 are 75.7, 132.1, 33.2, 48.4, 1377, and 59.4 μg/m3, respectively. Further, a 10 μg/m3 increment in the concentration of PM10, SO2, NO2, and CO corresponds to an increase of 0.28% (95% confidence interval (CI): 0.03-0.53%), 1.10% (95% CI: 0.09-2.11%), 1.82% (95% CI: 0.84-2.80%), and 0.03% (95% CI: 0.01-0.06%) in daily CP hospital outpatients, respectively. Furthermore, results indicated that outpatients under the age of 15 are more susceptible to the air pollutants, excluding O3. Meanwhile, males might be more susceptible, and effect estimates appear slightly stronger in the cool season. Therefore, we should implement effective measures to manage air pollutants and reinforce protection of the high-risk population.

Abstract
OBJECTIVE The article demonstrates the experience of using laser fluorescence spectrometry (LFS) in the diagnosis of inflammatory diseases of pharynx, describes a method for recording spectra of pharyngeal tissues using the EnSpectr L405 hardware-software complex operating on the basis of laser radiation with a wavelength of 405 nm, and identifies characteristic features of spectral curves. PATIENTS AND METHODS The authors presented the characteristics of the spectra from the surface of the pharynx tissue of healthy volunteers, patients with chronic tonsillitis and granular pharyngitis. RESULTS The most informative parameters of the spectral curves were calculated, analyzing which it is possible to identify the morphometric, metabolic, functional features of the tissue of the tonsils and posterior pharyngeal wall in normal and pathological conditions. CONCLUSION The article illustrates the importance of developing highly sensitive and highly specific methods for the rapid diagnosis of inflammatory diseases of the pharynx. The presented technology can be used in clinical practice in future.

Abstract
BACKGROUND Sore throat frequently occurs in children aged between four and fifteen years and is often associated to inflammation of the upper respiratory tract mucosa. A reliable approach to limit the damage caused by inflammation and, therefore, to alleviate associated symptoms might be the protection of the mucosa. Aim of this study was to assess the efficacy and tolerability of a medical device, formulated as a gummy lozenge and containing a combination of natural functional components (Erysimum, aloe vera and Xilogel®) able to exert a barrier effect on the mucosa, as ancillary treatment in children with sore throat. METHODS This was an observational, prospective, parallel-group, multiple-dose trial of a medical device given in association to standard pharmacological prescribed therapy with an open label comparison vs. standard pharmacological prescribed therapy alone. The outcome measures of the study were assessed at baseline and after three days of treatment. RESULTS One hundred and twelve school children with sore throat symptoms were recruited for this study and 69 were assigned to the group taking the study product. At the end of the treatment a statistically higher reduction in Sore Throat Pain Intensity Score and Pharyngitis Symptom Score was observed in the group taking the medical device. Moreover, the treatment with the medical device is associated to a statistically significant higher improvement of Child's General Conditions. The pediatrician assessed the efficacy and tolerability of the product under study as good/very good in 91% and 94%, respectively, of treated children. The consumer satisfaction questionnaire revealed that most of the children taking the lozenge rated it very positively in regard to its flavor and easiness of administration. CONCLUSIONS The medical device used in this study may represent a valid choice as an adjuvant treatment in children with sore throat associated to upper respiratory tract infection.

Systematic Review of Herbal Tea (a Traditional Chinese Treatment Method) in the Therapy of Chronic Simple Pharyngitis and Preliminary Exploration about Its Medication Rules. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:9458676. [PMID: 31662783 PMCID: PMC6791273 DOI: 10.1155/2019/9458676] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 07/25/2019] [Accepted: 08/21/2019] [Indexed: 12/29/2022]
Abstract
Background Chronic simple pharyngitis (CSP) is a common clinical chronic respiratory inflammation with persistent and intransigent symptoms. We analyzed the clinical data to find the evidence that herbal tea, a traditional Chinese medicine treatment in China, could improve the symptoms of CSP patients in a simple way. Methods We systematically reviewed the clinical data of randomized controlled treatments from April 2019 and evaluated the results using the improved Jadad scale and the Cochrane bias risk assessment tool. RevMan 5.3 software was used for chart analysis. In addition, we used Excel to conduct frequency statistics on Chinese herbs from included articles and analyze its medication rules. Results Among the collection of 161 articles, 6 RCTs published in Chinese journals were included in this review. The methodological quality of the treatments was low, and most of them only provide diagnostic criteria. Inclusion and exclusion criteria were not specified, and none of the 6 RCTs used the blind method on the result evaluator. Furthermore, only one RCT evaluated the baseline level variance. For these reasons, we did not make a network meta-analysis. Conclusions The traditional Chinese herbs involved in herbal tea did have ingredients to alleviate CSP symptoms. However, our research showed that the current research could not draw any credible conclusions on the curative effect of herbal tea, which indicated that the overall level of TCM clinical research needs to be improved to evaluate the efficacy of herbal tea.

Abstract
Background: In the pediatric population, acute pharyngo-tonsillitis represents one of the most frequent causes of access to outpatient treatment and use of antibiotics. In frequent tonsillitis, the pharmacological approach is no longer effective, and, therefore, surgery becomes the treatment of choice. Methods: This study compares the prophylactic efficacy of Streptococcus salivarius K12 (Bactoblis®) in children with recurrent pharyngo-tonsillitis treated vs untreated, with a 12 -month follow-up. The primary objectives are: The incidence of recurrence of pharyngo-tonsillar episodes and the concomitant use of other drugs. Secondary objectives are: tolerability of the treatment, the effectiveness in terms of clinical improvement, days of absence from school, reduction of the use of standard therapies, and cancellation from the surgical planning list. Results: Patients belonging to group A (treated with K12 for 90 days) were 24 males and 26 females, mean age 6.6 years (SD=1.57), those belonging to group B (untreated) were 23 males and 27 females, average age 6.8 years (SD=1.72). In the follow-up, group A reported 26 inflammatory pharyngo-tonsillary episodes in the first trimester, unlike group B, who reported 72 in the second trimester. This has shown a lower incidence (3.38%) of the disease compared to group B (6.66%), for a total of 169 inflammatory pharyngo-tonsillary episodes in group A against 333 in group B. A reduction in days of school absence of 429 days in group A and 927 days in the control group (P<0.01) was also noted. Finally, 14 children of group A (28%) underwent adenotonsillectomy, against the whole group B. No adverse events were reported. Conclusion: The efficacy of K12 on the prevention of pharyngo-tonsillar infections, the decrease in the use of antibiotics and the improvement of the overall quality-of-life was confirmed, with a decreased number of absences from school and fewer patients undergoing surgery.

Abstract
Chronic pharyngitis is a common disease, which has a long duration and a wide range of onset. It is easy to misdiagnose by mistaking it with other diseases, such as chronic tonsillitis, by using common diagnostic methods. In order to reduce costs and avoid misdiagnosis, the search for an affordable and rapid diagnostic method is becoming more and more important for chronic pharyngitis research. Speech disorder is one of the typical symptoms of patients with chronic pharyngitis. This paper introduces a convolutional neural network model for diagnosis based on the typical symptom of speech disorder. First of all, the voice data is converted into a speech spectrogram, which can better output the speech characteristic information and lay a foundation for computer diagnosis and discrimination. Second, we construct a deep convolutional neural network for the diagnosis of chronic pharyngitis through the design of the structure, the design of the network layer, and the description of the function. Finally, we perform a parameter optimization experiment on the convolutional neural network and judge the recognition efficiency of chronic pharyngitis. The results show that the convolutional neural network has a high recognition rate for patients with chronic pharyngitis and has a good diagnostic effect.

Probiotics Streptococcus salivarius 24SMB and Streptococcus oralis 89a interfere with biofilm formation of pathogens of the upper respiratory tract. BMC Infect Dis 2018; 18:653.

Abstract
Background Infections of the ears, paranasal sinuses, nose and throat are very common and represent a serious issue for the healthcare system. Bacterial biofilms have been linked to upper respiratory tract infections and antibiotic resistance, raising serious concerns regarding the therapeutic management of such infections. In this context, novel strategies able to fight biofilms may be therapeutically beneficial and offer a valid alternative to conventional antimicrobials. Biofilms consist of mixed microbial communities, which interact with other species in the surroundings and communicate through signaling molecules. These interactions may result in antagonistic effects, which can be exploited in the fight against infections in a sort of “bacteria therapy”. Streptococcus salivarius and Streptococcus oralis are α-hemolytic streptococci isolated from the human pharynx of healthy individuals. Several studies on otitis-prone children demonstrated that their intranasal administration is safe and well tolerated and is able to reduce the risk of acute otitis media. The aim of this research is to assess S. salivarius 24SMB and S. oralis 89a for the ability to interfere with biofilm of typical upper respiratory tract pathogens. Methods To investigate if soluble substances secreted by the two streptococci could inhibit biofilm development of the selected pathogenic strains, co-cultures were performed with the use of transwell inserts. Mixed-species biofilms were also produced, in order to evaluate if the inhibition of biofilm formation might require direct contact. Biofilm production was investigated by means of a spectrophotometric assay and by confocal laser scanning microscopy. Results We observed that S. salivarius 24SMB and S. oralis 89a are able to inhibit the biofilm formation capacity of selected pathogens and even to disperse their pre-formed biofilms. Diffusible molecules secreted by the two streptococci and lowered pH of the medium revealed to be implied in the mechanisms of anti-biofilm activity. Conclusions S. salivarius 24SMB and S. oralis 89a possess desirable characteristics as probiotic for the treatment and prevention of infections of the upper airways. However, the nature of the inhibition appear to be multifactorial and additional studies are required to get further insights.

Abstract
Traditionally, probiotics are linked to the good health of the intestine and most clinical studies focus on that field. Evidence of oral probiotic use for ear and oral cavity disease prevention with impact on human health is limited. This work reviews existing studies and literature on Streptococcus salivarius K12 as an oral probiotic and effects of S. salivarius K12 on human ear and oral cavity human health. The studies were accessed via database searches: MEDLINE, PubMed, and Elsevier. The search included/focused on/encompassed publications from 2003 to 2016 with keywords related to K12 Streptococcus salivarius, bacteriocin-like inhibitory substances (BLIS) K12, probiotic K12 salivarius, and K12 probiotic health effects. Only a small amount of studies was identified: the total of 68 studies was identified, 35 of which were relevant after screening, and 9 were included in the final analysis. Very little literature is available about the association/correlation between/connection/interrelation of S. salivarius K12 with/and human ear and oral cavity health. S. salivarius K12 may have a role in reducing the occurrence and/or severity of secretory otitis media (SOM) and also in prevention of streptococcal and viral pharyngotonsillitis in children. Research highlights that S. salivarius K12 has shown promising results in treatment of halitosis, but data are still deficient. Further studies need to be initiated to improve understanding of the association of oral probiotic S. salivarius K12 with human ear and oral cavity health.

Abstract
Group A Streptococcus (GAS) strains are lately classified on the basis of sequence variations in the emm gene encoding the M protein, but despite the high number of distinct emm genotypes, the spectrum of phenotypes varying from invasive suppurative to non-suppurative GAS-related disorders has still to be defined. The relationship of GAS types with the uprising of acute rheumatic fever (ARF), a multisystemic disease caused by misdirected anti-GAS response in predisposed people, is also obscure. Studies published over the last 15 years were retrieved from PubMed using the keywords: "Streptococcus pyogenes" or "group A Streptococcus" and "acute rheumatic fever": the prevalence of peculiar emm types across different countries of the world is highly variable, depending on research designs, year of observation, country involved, patients' age, and gender. Most studies revealed that a relatively small number of specific emm/M protein types can be considered "rheumatogenic", as potentially characterized by the possibility of inducing ARF, with remarkable differences between developing and developed countries. The association between emm types and post-streptococcal manifestations is challenging, however surveillance of disease-causing variants in a specific community with high rate of ARF should be reinforced with the final goal of developing a potential primary prophylaxis against GAS infections.

Abstract
BACKGROUND Acute viral tonsillitis is an upper respiratory tract infection prevalent in school-aged children. Because this condition is self-limiting, conventional treatment options are usually palliative. Homeopathic remedies are a useful alternative to conventional medications in acute uncomplicated upper respiratory tract infections in children, offering earlier symptom resolution, cost-effectiveness, and fewer adverse effects. This study aimed to determine the efficacy of a homeopathic complex on the symptoms of acute viral tonsillitis in African children in South Africa. METHODS This was a randomized, double-blind, placebo-controlled, 6-day pilot study. Thirty children, age 6 to 12 years, with acute viral tonsillitis were recruited from a primary school in Gauteng, South Africa. Participants took two tablets of the medication four times daily. The treatment group received lactose tablets medicated with the homeopathic complex (Atropa belladonna D4, Calcarea phosphoricum D4, Hepar sulphuris D4, Kalium bichromat D4, Kalium muriaticum D4, Mercurius protoiodid D10, and Mercurius biniodid D10). The placebo consisted of the unmedicated vehicle only. The Wong-Baker FACES Pain Rating Scale measured pain intensity, and a Symptom Grading Scale assessed changes in tonsillitis signs and symptoms. RESULTS The treatment group had a statistically significant improvement in the following symptoms compared with the placebo group: pain associated with tonsillitis, pain on swallowing, erythema and inflammation of the pharynx, and tonsil size. CONCLUSION The homeopathic complex used in this study exhibited significant anti-inflammatory and pain-relieving qualities in children with acute viral tonsillitis. No patients reported any adverse effects. These preliminary findings are promising; however, the sample size was small and therefore a definitive conclusion cannot be reached. A larger, more inclusive research study should be undertaken to verify the findings of this study.

Abstract
Chronic pharyngitis is chronic inflammation that is often caused by repeated occurrences of acute pharyngitis or upper respiratory tract infections, including Streptococcus and Staphylococcus. The present study aimed to investigate the effects of Yanshu spraying agent (Yanshu) in relieving chronic pharyngitis, as well as the possible underlying mechanisms. The results revealed that Yanshu inhibited chronic inflammation in ammonia-induced chronic pharyngitis in rabbits and cotton pellet-induced granuloma tissue formation in rats. Yanshu also demonstrated antibacterial effects on Streptococcus and Staphylococcus in vitro. Yanshu did not exhibit any effects on the immune system, including the spleen and thymus indexes, immunocyte count and monocyte-macrophage function, when compared with the effects of dexamethasone. Therefore, the results of the present study indicate that Yanshu may relieve chronic pharyngitis via its anti-inflammatory and antibacterial activities.

Abstract
Background Streptococcus salivarius K12 is an oral probiotic strain releasing two lantibiotics (salivaricin A2 and salivaricin B) that antagonize the growth of S. pyogenes, the most important bacterial cause of pharyngeal infections in humans also affected by episodes of acute otitis media. S. salivarius K12 successfully colonizes the oral cavity, and is endowed with an excellent safety profile. We tested its preventive role in reducing the incidence of both streptococcal and viral pharyngitis and/or tonsillitis in children. Materials and methods We enrolled 61 children with a diagnosis of recurrent oral streptococcal disorders. Thirty-one of them were enrolled to be treated daily for 90 days with a slow-release tablet for oral use, containing no less than 1 billion colony-forming units/tablet of S. salivarius K12 (Bactoblis®), and the remaining 30 served as the untreated control group. During treatment, they were all examined for streptococcal infection. Twenty children (ten per group) were also assessed in terms of viral infection. Secondary end points in both groups were the number of days under antibiotic and antipyretic therapy and the number of days off school (children) and off work (parents). Results The 30 children who completed the 90-day trial with Bactoblis® showed a significant reduction in their episodes of streptococcal pharyngeal infection (>90%), as calculated by comparing the infection rates of the previous year. No difference was observed in the control group. The treated group showed a significant decrease in the incidence (80%) of oral viral infections. Again, there was no difference in the control group. With regard to secondary end points, the number of days under antibiotic treatment of the treated and control groups were 30 and 900 respectively, days under antipyretic treatment 16 and 228, days of absence from school 16 and 228, and days of absence from work 16 and 228. The product was well tolerated by the subjects, with no side effects, and only one individual reported bad product palatability and dropped out. Conclusion Prophylactic administration of S. salivarius K12 to children with a history of recurrent oral streptococcal disease resulted in a considerable reduction of episodes of both streptococcal and viral infections and reduced the number of days under antibiotic and/or antipyretic therapy and days of absence from school or work.

Abstract
Background Bacteria including Chlamydophila pneumoniae, Mycoplasma pneumoniae, and anaerobic bacteria such as Fusobacterium necrophorum have been implicated as etiological agents of chronic pharyngitis in Western literature. Because there are no data regarding this from India, the authors undertook this study. Study Design Prospective case-control study. Setting Tertiary-level medical college and hospital. Method In total, 343 consecutive adults with persistent throat pain and/or irritation (duration ≥3 months) were screened for known causes of pharyngitis by a thorough clinical and endoscopic examination. In 71 patients, the evaluation performed was unable to determine any cause, and these were considered cases. An enzyme-linked immunosorbent assay test to detect IgA and IgG antibodies to C pneumoniae and M pneumoniae was performed on 66 of these cases and 62 controls. The posterior pharyngeal swabs taken from both the cases and controls were subjected to aerobic and anaerobic culture. Results Individuals with chronic pharyngitis had a 3.43 times odds of being seropositive for C pneumoniae as compared with controls ( P = .001; odds ratio = 3.43). Aerobic organisms and M pneumoniae did not seem to be significant etiological agents for chronic pharyngitis. On the contrary, isolation of Fusobacterium spp was found to be significantly more in controls as compared with cases. Conclusion This study suggests an association between IgA antibodies to C pneumoniae and chronic pharyngitis. Further studies using more specific tests combined with long-term follow-up are needed to confirm these findings.
