RESUMO
BACKGROUND: Group A Streptococcus (GAS) causes an estimated 5.2 million outpatient visits for pharyngitis annually in the United States, with incidence peaking in winter, but the annual spatiotemporal pattern of GAS pharyngitis across the United States is poorly characterized. METHODS: We used outpatient claims data from individuals with private medical insurance between 2010 and 2018 to quantify GAS pharyngitis visit rates across U.S. census regions, subregions, and states. We evaluated seasonal and age-based patterns of geographic spread and the association between school start dates and the summertime upward inflection in GAS visits. RESULTS: The South had the most visits per person (yearly average, 39.11 visits per 1000 people; 95% confidence interval, 36.21-42.01) and the West had the fewest (yearly average, 17.63 visits per 1000 people; 95% confidence interval, 16.76-18.49). Visits increased earliest in the South and in school-age children. Differences in visits between the South and other regions were most pronounced in the late summer through early winter. Visits peaked earliest in central southern states, in December to January, and latest on the coasts, in March. The onset of the rise in GAS pharyngitis visits correlated with, but preceded, average school start times. CONCLUSIONS: The burden and timing of GAS pharyngitis varied across the continental United States, with the South experiencing the highest overall rates and earliest onset and peak in outpatient visits. Understanding the drivers of these regional differences in GAS pharyngitis will help in identifying and targeting prevention measures.

PURPOSE: Streptococcus pyogenes (mostly termed group A Streptococcus - GAS) is the most important bacterial causative of pharyngitis. However, epidemiology of GAS pharyngitis is not widely established. This study describes GAS pharyngitis cases and emm-type distribution in a prospective study covering over 2 years in two Hospital Districts in Finland. METHODS: A prospective, systematic collection of GAS pharyngitis isolates was conducted between March 2018 and December 2020 in two large Hospital Districts in Finland. Patient characteristics (age, gender) were included if available. All GAS isolates collected were emm typed. RESULTS: Altogether 1320 GAS pharyngitis strains were collected, 904 in the Hospital District 1 (HD1) and 416 in Hospital District 2 (HD2). In HD1, age and gender data were available. Females were overrepresented (58% of all cases). In addition, the age and gender distributions were noted to be significantly different (p < 0.0001) with females having a more uniform distribution until age of 40. emm28 was common among the age group of 20-29-year-olds and emm89 in children under 10 years of age, respectively. In HD1, most of the isolates were collected during winter and autumn months. Significant differences by season in the frequency of emm12, emm89, emm75 and group of "others" were observed. CONCLUSION: Age distribution among GAS pharyngitis cases was significantly different between genders (p < 0.0001). In addition, age group specific and seasonal variations in emm GAS types causing the disease were observed. These findings warrant further investigation, especially for understanding population-based spread of GAS even in more detail.

The spectrum of diseases caused by Streptococcus pyogenes (Strep A) ranges from superficial to serious life-threatening invasive infections. We conducted a scoping review of published articles between 1980 and 2021 to synthesize evidence of state transitions across the Strep A disease spectrum. We identified 175 articles reporting 262 distinct observations of Strep A disease state transitions. Among the included articles, the transition from an invasive or toxin-mediated disease state to another disease state (i.e., to recurrent ARF, RHD or death) was described 115 times (43.9% of all included transition pairs) while the transition to and from locally invasive category was the lowest (n = 7; 0.02%). Transitions from well to any other state was most frequently reported (49%) whereas a relatively higher number of studies (n = 71) reported transition from invasive disease to death. Transitions from any disease state to locally invasive, Strep A pharyngitis to invasive disease, and chronic kidney disease to death were lacking. Transitions related to severe invasive diseases were more frequently reported than superficial ones. Most evidence originated from high-income countries and there is a critical need for new studies in low- and middle-income countries to infer the state transitions across the Strep A disease spectrum in these high-burden settings.

The burden of group A streptococcus (GAS) infection and its rheumatic sequelae remains dramatically high, especially in low-income countries. Recently, an increased number of Acute Rheumatic Fever (ARF) cases was documented in many regions of Italy. The diagnosis of rheumatic sequelae relies on clinical signs and on the evaluation of the Antistreptolysin O titre (ASO), whose variations are globally reported. To re-examine the standard reference value of ASO titre, by measuring either its upper limit of normal (ULN) in a population of healthy children (HC) or comparing these values with streptococcal antibodies registered in a cohort of patients affected by the rheumatic sequelae of GAS infection. We performed a multicenter retrospective study. We enrolled 125 HC, aged 2-17 years, and a total of 181 patients affected by ARF, acute streptococcal pharyngitis, post-streptococcal arthritis, Henoch-Schönlein purpura and erythema nodosum, divided into four groups. The levels of ASO and anti-deoxyribonuclease B (anti-DNase B) titres were analyzed and compared among the various groups. Moreover, the 80th percentile value was calculated and established as the ULN for ASO titre in HC group. The ULN for ASO titre in overall HC group was 515 IU/mL, resulting in higher than used in the routine investigation. The ASO titre was significantly higher in patients with rheumatic sequelae compared with HC group, with a peak in the age between 5 and 15 years. Conclusion: Our study established a new ULN normal value of streptococcal serology in a childhood and adolescent population of Italy, suggesting the need to extend this revaluation to the critical areas, in order to avoid underestimating ARF diagnosis. The correct interpretation of ASO and anti-DNase B values in the context of rheumatic diseases has been discussed. What is Known: ⢠The global burden of disease caused by group A streptococcus is not known and remains an important cause of morbidity and mortality. Acute rheumatic fever continues to be a serious worldwide public health problem and a recent recurrence of group A streptococcus infection cases is observed. ⢠The streptococcal sequelae requires evidence of preceding streptococcal infection, commonly elevated streptococcal antibody titre, but the upper limit for these titres varies considerably based on age group, region, and origin. What is New: ⢠This study provides population-specific values for streptococcal antibody titres in Italy. ⢠Interpret the results of group A streptococcal antibody tests within the clinical context.

Acute genital ulcers can affect females of all ages. In children, they often appear as an emergency and remain a diagnostic challenge for pediatricians, gynecologists and dermatologists. Prompt diagnosis and identification of disease- related factors help to implement appropriate treatment. Firstly, it is crucial to properly compile the past medical history of the patient. Past infectious, autoimmune, malignant or traumatic conditions, as well as vaccinations may contribute to the occurrence of acute genital ulcers. Moreover, new infectious agents, such as severe acute respiratory syndrome coronavirus 2 and vaccinations against Coronavirus disease of 2019, may play a significant role in the development of atypical clinical symptoms. Here we present a case of a 12-year-old girl with acute genital ulcers. Additional symptoms accompanying the ulcer included: abdominal pain, nausea, vomiting, dysuria, vulvar pain and fever. Blood test showed leukocytosis, especially neutrophilia and monocytosis and increased levels of c-reactive protein and procalcitonin. Serological tests for the most common infections were negative. Moreover, the patient had a history of autoimmune diseases. She had periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome, and IgA vasculitis, also known as Henoch-Schönlein purpura in her past medical history. Additionally, she was vaccinated against SARS-CoV-2 shortly before the lesions appeared.

BACKGROUND: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major public health issues. Although the primary and secondary prevention of RHD through appropriate management of bacterial pharyngitis and ARF are well-described in the literature, few studies address the knowledge, attitude, and practice (KAP) of developing countries. We aimed to evaluate the KAP of the frontline physicians in Egyptian university hospitals regarding pharyngitis and ARF. METHODS: We employed a cross-sectional design between September 1st, 2022, and January 31st, 2023 using a self-administered questionnaire in 21 Egyptian universities. The questionnaire was developed based on previous studies and recent guidelines and included four domains: sociodemographic data, knowledge, attitude, and practice regarding pharyngitis and ARF. We utilized both online (Google Forms) and paper surveys. Frontline physicians, including interns, residents, and assistant lecturers, were conveniently invited to participate. Furthermore, with the help of participating phycisians in recruiting their colleagues, we utilized the snowball method. Data were analyzed using IBM SPSS version 27 software. RESULTS: The final analysis included 629 participants, of whom 372 (59.1%) were males and 257 (40.9%) had direct contact with ARF patients. Most participants (61.5%) had a fair knowledge level while 69.5% had a fair level of practice regarding ARF and pharyngitis. Higher satisfactory knowledge levels were noted regarding pharyngitis (17.1% vs. 11.3%; p-value: 0.036) and ARF (26.8% vs. 18%; p-value: 0.008) among physicians dealing directly with ARF cases compared to physicians in departments not dealing directly with ARF cases. Physicians in Cairo region universities had significantly higher levels of satisfactory knowledge about ARF compared to Delta and Upper Egypt region universities (p = 0.014). Delta region universities showed significantly lower levels of practice compared to Cairo and Upper Egypt region universities (p = 0.027). The most frequently recognized barriers against health promotion were low socioeconomic status (90.3%) and lack of adequate public education (85.8%). CONCLUSIONS: Despite the fair knowledge and practice levels towards bacterial pharyngitis and ARF among participants, many gaps were still identified that might contribute to RHD prevalence. Educational interventions should be implemented by updating the local guidelines in Egypt for diagnosis and management based on the most recent guidelines.

BACKGROUND: The Finnish treatment guidelines for sore throat were updated in June 2020. The aim of this study was to determine how the publication of these guidelines affected the treatment of pediatric patients, particularly through the use of the Centor criteria, C-reactive protein tests, and microbiological testing in the diagnosis of Group A ß-hemolytic streptococci tonsillitis. METHODS: We conducted a retrospective single-center before-and-after cohort study in Finland from 2019 to 2022. We included all patients who visited the pediatric emergency department and were diagnosed with tonsillitis or pharyngitis. RESULTS: We included 246 patients who were admitted before the guidelines were updated and 219 patients after. Only two patients in the after group had a Centor score reported in their patient records. Rapid antigen tests were administered to 231 patients (93.9%) before the update and 202 patients (92.2%) after (proportion difference of 1.7%, CI -3.0-6.6%). C-reactive protein was taken from 193 patients (78.5%) before the update and 189 patients (86.3%) after (proportion difference of 7.8%, CI 0.1-14.7%). CONCLUSIONS: Centor scores were not used as recommended in the guidelines and did not impact the use of microbiological or C-reactive protein testing. More education and examining the preconceptions of health care personnel is required to implement the updated treatment guidelines in clinical practice.

For preoperative skin antisepsis, alcohol-containing iodine solutions and octenidine are suitable. For wound antisepsis, polyhexanide and hypochlorous acid (HOCL) are also available, but only PVP-iodine and HOCL can be applied to cartilage. Chlorhexidine should only be used as mouth- and bodywash for Staphylococcus aureus (MRSA) decolonization. For the many other throat antiseptics, evidence of clinical efficacy is lacking. For decolonization of the nares, polyhexanide and octenidine are available as nasal gels, but these are inferior to mupirocin for MRSA decolonization. PVP-iodine and HOCL are safe to use for nasal irrigation, but only HOCL has proven effective to improve symptoms of chronic rhinosinusitis. All antiseptics exhibit a certain ototoxicity. With an intact eardrum, acetic acid-containing eardrops can be used to prevent and treat external otitis and myringitis. When the eardrum is perforated, only alcohol-free PVP-iodine and HOCL may be used.

OBJECTIVE: This study aimed to assess the cause of acute pharyngitis and determine the duration of severe and moderate symptoms based on the aetiology. DESIGN: Prospective observational study. SITE: One urban health care centre. PARTICIPANTS: Patients aged 15 or older with acute pharyngitis were included. INTERVENTIONS: Bacterial identification was carried out in the microbiology lab using MALDI-TOF in two throat samples. Patients received a symptom diary to return after one week. MAIN MEASUREMENTS: Number of days with severe symptoms, scoring 5 or more in any of the symptoms included in the symptom diary, and moderate symptoms, scoring 3 or more. RESULTS: Among the 149 patients recruited, beta-haemolytic streptococcus group A (GABHS) was the most common aetiology. Symptoms and signs alone as well as the mean Centor score cannot distinguish between GABHS and other bacterial causes in patients with acute pharyngitis. However, there was a trend indicating that infections caused by Streptococcus dysgalactiae and Streptococcus agalactiae presented more severe symptoms, whereas infections attributed to the Streptococcus anginosus group, Fusobacterium spp., and those where oropharyngeal microbiota was isolated tended to have milder symptoms. S. dysgalactiae infections showed a trend towards longer severe and moderate symptom duration. CONCLUSION: GABHS was the most prevalent, but group C streptococcus caused more severe and prolonged symptoms.
RESUMO
INTRODUCTION: Respiratory tract infections in children are an interdisciplinary problem that pediatricians, allergists, laryngologists and immunologists encounter on a daily basis. In the youngest children, these diseases are caused by the structure of the respiratory tract, which is shorter and narrower than in an adult, as well as the immaturity of the immune system. Among all children under 5 years of age hospitalized due to respiratory diseases, 20% of cases are acute respiratory infections. OBJECTIVE: The aim of the study is to discuss selected respiratory diseases in children aged 0-18 years hospitalized at the Pediatric Hospital in Bielsko-Biala. MATERIAL AND METHODS: In June 2023, statistical data from the Pediatric Hospital was received regarding the number of hospitalized children aged 0-18 in 2015-2022. This article covers the following respiratory diseases: acute laryngitis, acute pharyngitis, pneumonia, bronchitis and bronchiolitis, bronchial asthma, adenoid hypertrophy and palatine tonsil hypertrophy coexisting with adenoid hypertrophy. Then, a table was prepared illustrating the trends of individual disease entities in the discussed time period. RESULTS: A total of 5,573 hospitalizations were analyzed for the period from 2015-2022. The largest group of children (1,583) were hospitalized due to acute bronchitis and bronchiolitis (28.41%), due to hypertrophy of the adenoid (1,093) and palatine tonsils (1,039), which is 19.6% and 18.64% respectively. The smallest number of children and adolescents were hospitalized due to acute laryngotracheitis (474) and pharyngitis (361), which is 8.51% and 6.47%, respectively, and due to asthma (54), which is 0.97%. It has been observed that from 2017 to 2022 the number of hospitalized patients is constantly increasing due to acute pharyngitis and pneumonia, and from 2018 to 2022 due to acute laryngotracheitis. CONCLUSIONS: In the analyzed Pediatric Hospital in Bielsko-Biala, the number of hospitalized children (from 0 to 18 years of age) due to pharyngitis, laryngotracheitis and pneumonia increased during the COVID-19 pandemic (2020-2022). The number of hospitalized patients due to pneumonia increased by as many as 70 from 2021 (197) to 2022 (267). In the case of hospitalizations for pharyngitis during the COVID-19 period, the number ranged from 46 in 2019 to 69 in 2022. Also in the case of acute laryngotracheitis in the period 2019-2022, the number of hospitalized young patients increases and ranges from 61 to 76. Respiratory tract infections are an important and common health problem for children. The vast majority of respiratory infections are caused by viruses.

This study systematically combed the existing evidence of Houyanqing Oral Liquid in the treatment of acute pharyngitis from the "6+1" dimensions of safety, effectiveness, economy, innovation, suitability, accessibility, and characteristics of traditional Chinese medicine(TCM) and carried out qualitative and quantitative analysis of the data from each dimension. The multi-criteria decision analysis(MCDA) model and CSC v2.0 were used to evaluate the clinical value of this drug, so as to provide evidence for the selection of essential drugs in the department of otolaryngology and for medical and health decision-making. The dimensions are graded A, B, C, or D. The adverse reactions of Houyanqing Oral Liquid in the treatment of acute pharyngitis were mainly manifested as abdominal pain, diarrhea, rash, etc., which were relieved after drug withdrawal. In terms of safety, it was considered that Houyanqing Oral Liquid had controllable risk and high safety, which was rated as grade B. Compared with ribavirin aerosol alone, Houyanqing Oral Liquid combined with ribavirin aerosol can significantly improve the total response rate, shorten the time to abatement of fever and di-sappearance of throat pain and mucosal congestion, and alleviate mucosal congestion and cough with sputum. With medium-quality evidence, the effectiveness was rated as grade B. Compared with ribavirin aerosol alone, Houyanqing Oral Liquid combined with ribavirin aerosol had cost-effectiveness advantages in the treatment of acute pharyngitis, and its economy was rated as grade C with the evidence of general quality. For acute pharyngitis, Houyanqing Oral Liquid can shorten the disease course and obviously relieve sore throat. Moreover, it can be used for the treatment of radioactive pharyngitis and oral ulcer, and thus its innovation was rated as grade B. With convenient and simple administration and standard and complete drug information, the suitability of this drug was rated as grade B. Houyanqing Oral Liquid is derived from the folk prescription in Hunan province and has been subjected to real-world studies, and thus the TCM characteristics was rated as grade B. According to the ratings of all the dimensions, the comprehensive value of Houyanqing Oral Liquid in the clinical treatment of acute pharyngitis was determined as grade B, with sufficient evidence and clear results. It is suggested that the results should be conditionally converted into relevant policy of clinical basic drug management according to procedures.

OBJECTIVE: Aim: To study the Respiratory pathology of the upper respiratory tract, markers of the inflammatory response of the organism, Oxidative stress, Metabolic adaptation and possibilities of correction. PATIENTS AND METHODS: Materials and Methods: The study group (n=111) included school-aged children (10-14 years old). The general group of inflammatory diseases of the respiratory tract (J000-J06) was considered, with a diagnosis of acute respiratory infection (ARI) of viral and bacterial origin and included local inflammationof the upper respiratory tract with presentation of acute pharyngitis (68.0%), acute bronchitis (22,0%), acute tonsillitis (10,0%). RESULTS: Results: Dynamic observation of groups of children who received optimized (group 1, n=60) and basic (group 2, n=51) treatment was carried out. The level of the erythrocyte pool correlated with IL-1 (r=-0,29, p=0,03), IL-4 (r=0,32, p=0,01), TNF-α (r=-0,35 , p=0,006). Creatinine value correlated with IL-10 (r=0,3, p=0,005), γ-IFN (r=0,42, p=0,001), TNF-α (r=0,25, p=0,05). Correlations of ferritin presented positive correlation values with the level of total protein (r=0,26, p=0,04) and TNF-α (r=0,41, p=0,001). CONCLUSION: Conclusions: After the optimized treatment, there was a significant decrease in the reliable levels of CRP and γ-IFN by 7 and 4,4 times (by groups) and 5,8 and 3,2 times (by groups), respectively. Correlation relationships of urea levels with IL-2,4 were detected. The level of the erythrocyte pool correlated with IL-1,4, TNF-α, Ferritin presented positive correlation values with the level of total protein,TNF-α .

Chronic pharyngitis (CP) is one of the most common diseases of the oropharynx. The number of referrals from patients with CP reaches 70% of the total number of referrals to an otorhinolaryngologist. The development of this disease is facilitated by the neuro-reflex factor and a violation of trophic and metabolic processes. It should be noted that of all forms of CP, the greatest impact on the quality of life is noted precisely in atrophic pharyngitis (AP), due to the presence of pronounced subjective sensations from the oropharynx. Many of the modern methods of treatment do not provide a lasting effect due only to the application, superficial local effect on the altered mucous membrane of the posterior pharyngeal wall, without taking into account the changes caused by a violation of trophic processes in the tissue. A promising direction in the treatment of atrophic pharyngitis is the use of a combined technique - ozone therapy and low-intensity laser therapy. The article presents the results of the application of fine-drip irrigation of the mucous membrane of the posterior pharyngeal wall with Ozonide oil in combination with low-intensity laser radiation on the projection of vessels supplying blood to the middle parts of the oropharynx. OBJECTIVE: Improving the effectiveness of treatment of patients with atrophic pharyngitis through the use of ozone therapy and low-intensity laser therapy. MATERIAL AND METHODS: A single-center experimental controlled randomized open-label study of 90 patients with AP aged 18 and over was conducted. All patients were randomly divided into three groups depending on the treatment performed: group I - traditional treatment method (rinsing the oropharynx with antiseptic solutions, the use of tablets for resorption), group II - treatment with ozone therapy (fine drip irrigation of the mucous membrane of the posterior pharyngeal wall with Ozonide oil), group III - treatment with ozone therapy and laser therapy. During the examination of patients, anamnesis collection, examination of ENT organs, cytological and microbiological examination of the mucous membrane of the posterior pharyngeal wall, contact endoscopy of the mucous membrane of the posterior pharyngeal wall were performed. 5-point visual analogue scales (VAS) were used to assess complaints and pharyngoscopic signs. RESULTS: Our results showed a statistically significant improvement in the quality of life of patients with AP (p=0.012), an improvement in the pharyngoscopic picture (p=0.003). The results obtained by us indicate an improvement in microcirculation under the influence of ozone therapy and low-intensity laser radiation. The technique using ozone therapy and low-intensity laser therapy is characterized by a bactericidal and fungicidal effect. There is a decrease in the total contamination of the posterior wall of the oropharynx with pathogenic and saprophytic microflora (there is a decrease in the contamination of the posterior wall of the pharynx with saprophytic and pathogenic microflora (p≤0.05), the differences are statistically significant). The technique using ozone therapy and low-intensity laser therapy has a pronounced anti-inflammatory effect, which was expressed in a decrease in the severity of dyskeratosis and hyperkeratosis. Thus, the use of ozone therapy in combination with laser therapy opens up new prospects for pathogenetically sound and effective treatment of AP.

The results of a prospective open cohort study of the use of platelet-rich plasma (platelet-rich plasma - PRP) in patients with chronic pharyngitis during the exacerbation of the disease are presented. OBJECTIVE: To evaluate the clinical efficacy of autologous PRP in the treatment of chronic pharyngitis. MATERIAL AND METHODS: Autologous PRP was injected into the posterior pharyngeal wall as a course of endopharyngeal blockages as part of the complex therapy of chronic pharyngitis. Patients in the control group received standard therapy, without the use of autologous PRP. The effectiveness of the studied technique was evaluated by statistical analysis of the intensity of symptoms of the disease, determined by patients throughout the entire period of treatment in the patient's diary, as well as by analyzing data from mass spectrometry of microbial markers and bacteriological examination of the pharyngeal mucosa, collected at the beginning of the study and 14 days after completion of the course of therapy. CONCLUSION: The use of a course of endopharyngeal blockades with autologous platelet-rich plasma as part of the complex therapy of chronic pharyngitis, according to our estimates, provides a significant effect in the form of higher rates of reduction in the severity of symptoms of the disease, a significant reduction in the number of microorganisms deviating from the reference values (by 2 times or more), a decrease in the duration of the disease compared with the control group.

Pharyngitis can be caused by various pathogens, including viruses and bacteria. Group A streptococcus (GAS) is the most common bacterial cause of pharyngitis. However, distinguishing GAS pharyngitis from other types of upper respiratory tract infections is challenging in clinical settings. This often leads to empirical treatments and, consequently, the overuse of antimicrobial drugs. With the advancement of antimicrobial drug management and healthcare payment reform initiatives in China, reducing unnecessary testing and prescriptions of antimicrobial drugs is imperative. To promote standardized diagnosis and treatment of GAS pharyngitis, this article reviews various international guidelines on the clinical diagnosis and differential diagnosis of GAS pharyngitis, particularly focusing on clinical scoring systems guiding laboratory testing and antimicrobial treatment decisions for GAS pharyngitis and their application recommendations, providing a reference for domestic researchers and clinical practitioners.

This study aims to provide a comparison of the current recommendations about the management of acute pharyngitis. A literature search was conducted from January 2009 to 2023. Documents reporting recommendations on the management of acute pharyngitis were included, pertinent data were extracted, and a descriptive comparison of the different recommendations was performed. The quality of guidelines was assessed through the AGREE II instrument. Nineteen guidelines were included, and an overall moderate quality was found. Three groups can be distinguished: one group supports the antibiotic treatment of group A ß-hemolytic Streptococcus (GABHS) to prevent acute rheumatic fever (ARF); the second considers acute pharyngitis a self-resolving disease, recommending antibiotics only in selected cases; the third group recognizes a different strategy according to the ARF risk in each patient. An antibiotic course of 10 days is recommended if the prevention of ARF is the primary goal; conversely, some guidelines suggest a course of 5-7 days, assuming the symptomatic cure is the goal of treatment. Penicillin V and amoxicillin are the first-line options. In the case of penicillin allergy, first-generation cephalosporins are a suitable choice. In the case of beta-lactam allergy, clindamycin or macrolides could be considered according to local resistance rates. Conclusion: Several divergencies in the management of acute pharyngitis were raised among guidelines (GLs) from different countries, both in the diagnostic and therapeutic approach, allowing the distinction of 3 different strategies. Since GABHS pharyngitis could affect the global burden of GABHS disease, it is advisable to define a shared strategy worldwide. It could be interesting to investigate the following issues further: cost-effectiveness analysis of diagnostic strategies in different healthcare systems; local genomic epidemiology of GABHS infection and its complications; the impact of antibiotic treatment of GABHS pharyngitis on its complications and invasive GABHS infections; the role of GABHS vaccines as a prophylactic measure. The related results could aid the development of future recommendations. What is Known: ⢠GABHS disease spectrum ranges from superficial to invasive infections and toxin-mediated diseases. ⢠GABHS accounts for about 25% of sore throat in children and its management is a matter of debate. What is New: ⢠Three strategies can be distinguished among current GLs: antibiotic therapy to prevent ARF, antibiotics only in complicated cases, and a tailored strategy according to the individual ARF risk. ⢠The impact of antibiotic treatment of GABHS pharyngitis on its sequelae still is the main point of divergence; further studies are needed to achieve a global shared strategy.

BACKGROUND: Conflicting international guidelines exist on the management of sore throat by antibiotics. OBJECTIVES: To assess with the Appraisal of Guidelines for Research and Evaluation II (AGREE) instrument the quality of guidelines for uncomplicated acute group A beta-haemolytic streptococcal (GABHS) sore-throat. To make a sensitivity analysis restricted to guidelines with a rigour of development score higher than 60% and to describe their recommendations on scores, tests, and antibiotic therapy, including their justification. METHODS: A guideline literature review of acute GABHS sore throat, published between January 2000 and December 2019 in primary care and secondary care. The PubMed database, the Canadian Medical Association Infobase on Clinical Practice Guidelines and the International Network Guidelines were used. The quality of guidelines was assessed using the AGREE II instrument. The guidelines were classified into 2 categories: high-quality guidelines had to rate >60% for the rigour of development score, the others were classified as low-quality guidelines. RESULTS: Significant heterogeneity between the 15 guidelines concerned the scores of the 6 assessment domains. Among them, 6 guidelines presented a score above 60% with regards to the rigor of development domain and used a systematic literature search method, citing meta-analyses of recent randomised clinical trials. Most of the 6 high-quality guidelines no longer recommended the systematic use of diagnostic scores and tests, nor antibiotic therapy to prevent acute rheumatic fever or loco-regional complications, except for high-risk patients. CONCLUSION: Major discrepancies emphasise the need for only high-quality guidelines, based on adequately assessed evidence. Restricted antibiotic prescriptions to severe cases or high-risk patients would avoid antibiotic resistance.
RESUMO
INTRODUCTION: Although rapid antigen tests (RADTs) for group A streptococcus (GAS) can help diagnose group A streptococcal pharyngitis, little is known about the inappropriate use of these RADTs. METHODS: This retrospective observational study compared the appropriate vs. inappropriate use of RADTs in patients who had a RADT between January 2019 and August 2022. RADTs for patients with a low Centor score of 0-1 point were deemed inappropriate. RESULTS: Of the 1015 patients, 380 (37.4%) had inappropriate RADTs. Patients with asthma were associated with an increased risk of inappropriate testing. In contrast, during the coronavirus 2019 pandemic, outpatients and residents were associated with a reduced risk of inappropriate testing. Consequent to the inappropriate use of RADTs, 162 (16.0%) patients received potentially inappropriate antibiotics. CONCLUSIONS: Our results suggest that diagnostic stewardship for pharyngitis, including education for healthcare workers, is needed to reduce inappropriate test ordering and prevent unnecessary care.

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 (ß = 0.476, P < 0.001) and attitude (ß = 0.600, P < 0.001), and having family history of chronic pharyngitis showed positive effect on knowledge (ß = 0.580, P = 0.047), experienced with reflux symptoms showed positive effect on knowledge (ß = 0.838, P = 0.001) and attitude (ß = 0.631, P = 0.085). Moreover, knowledge showed positive effect on attitude (ß = 0.555, P < 0.001) and practice (ß = 0.351, P < 0.001). Attitude, in turn, showed positive effect on practice (ß = 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.

BACKGROUND: Sore throat is a common problem and a common reason for the overuse of antibiotics. A web-based tool that helps people assess their sore throat, through the use of clinical prediction rules, taking throat swabs or saliva samples, and taking throat photographs, has the potential to improve self-management and help identify those who are the most and least likely to benefit from antibiotics. OBJECTIVE: We aimed to develop a web-based tool to help patients and parents or carers self-assess sore throat symptoms and take throat photographs, swabs, and saliva samples for diagnostic testing. We then explored the acceptability and feasibility of using the tool in adults and children with sore throats. METHODS: We used the Person-Based Approach to develop a web-based tool and then recruited adults and children with sore throats who participated in this study by attending general practices or through social media advertising. Participants self-assessed the presence of FeverPAIN and Centor score criteria and attempted to photograph their throat and take throat swabs and saliva tests. Study processes were observed via video call, and participants were interviewed about their views on using the web-based tool. Self-assessed throat inflammation and pus were compared to clinician evaluation of patients' throat photographs. RESULTS: A total of 45 participants (33 adults and 12 children) were recruited. Of these, 35 (78%) and 32 (71%) participants completed all scoring elements for FeverPAIN and Centor scores, respectively, and most (30/45, 67%) of them reported finding self-assessment relatively easy. No valid response was provided for swollen lymph nodes, throat inflammation, and pus on the throat by 11 (24%), 9 (20%), and 13 (29%) participants respectively. A total of 18 (40%) participants provided a throat photograph of adequate quality for clinical assessment. Patient assessment of inflammation had a sensitivity of 100% (3/3) and specificity of 47% (7/15) compared with the clinician-assessed photographs. For pus on the throat, the sensitivity was 100% (3/3) and the specificity was 71% (10/14). A total of 89% (40/45), 93% (42/45), 89% (40/45), and 80% (30/45) of participants provided analyzable bacterial swabs, viral swabs, saliva sponges, and saliva drool samples, respectively. Participants were generally happy and confident in providing samples, with saliva samples rated as slightly more acceptable than swab samples. CONCLUSIONS: Most adult and parent participants were able to use a web-based intervention to assess the clinical features of throat infections and generate scores using clinical prediction rules. However, some had difficulties assessing clinical signs, such as lymph nodes, throat pus, and inflammation, and scores were assessed as sensitive but not specific. Many participants had problems taking photographs of adequate quality, but most were able to take throat swabs and saliva samples.
