ABSTRACT

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.

ABSTRACT

BACKGROUND: Systemic autoinflammatory disorders (SAIDs) represent a growing spectrum of diseases characterized by dysregulation of the innate immune system. The most common pediatric autoinflammatory fever syndrome, Periodic Fever, Aphthous Stomatitis, Pharyngitis, Adenitis (PFAPA), has well defined clinical diagnostic criteria, but there is a subset of patients who do not meet these criteria and are classified as undefined autoinflammatory diseases (uAID). This project, endorsed by PRES, supported by the EMERGE fellowship program, aimed to analyze the evolution of symptoms in recurrent fevers without molecular diagnosis in the context of undifferentiated AIDs, focusing on PFAPA and syndrome of undifferentiated recurrent fever (SURF), using data from European AID registries. METHODS: Data of patients with PFAPA, SURF and uSAID were collected from 3 registries including detailed epidemiological, demographic and clinical data, results of the genetic testing and additional laboratory investigations with retrospective application of the modified Marshall and PRINTO/Eurofever classification criteria on the cohort of PFAPA patients and preliminary SURF criteria on uSAID/SURF patients. RESULTS: Clinical presentation of PFAPA is variable and some patients did not fit the conventional PFAPA criteria and exhibit different symptoms. Some patients did not meet the criteria for either PFAPA or SURF, highlighting the heterogeneity within these groups. The study also explored potential overlaps between PFAPA and SURF/uAID, revealing that some patients exhibited symptoms characteristic of both conditions, emphasizing the need for more precise classification criteria. CONCLUSIONS: Patients with recurrent fevers without molecular diagnoses represent a clinically heterogeneous group. Improved classification criteria are needed for both PFAPA and SURF/uAID to accurately identify and manage these patients, ultimately improving clinical outcomes.

ABSTRACT

BACKGROUND: This randomized controlled trial aimed to evaluate the efficacy of preoperative inhaled budesonide combined with intravenous dexamethasone on postoperative sore throat (POST) after general anesthesia in patients who underwent thyroidectomy. METHODS: Patients who underwent elective thyroidectomy were randomly divided into the intravenous dexamethasone group (group A) and budesonide inhalation combined with intravenous dexamethasone group (group B). All patients underwent general anesthesia. The incidence and severity of POST, hoarseness, and cough at 1, 6, 12, and 24 hours after surgery were evaluated and compared between the 2 groups. RESULTS: There were 48 and 49 patients in groups A and B, respectively. The incidence of POST was significantly lower at 6, 12, and 24 hours in group B than that in group A (P < .05). In addition, group B had a significantly lower incidence of coughing at 24 hours (P = .047). Compared with group A, the severity of POST was significantly lower at 6 (P = .027), 12 (P = .004), and 24 (P = .005) hours at rest, and at 6 (P = .002), 12 (P = .038), and 24 (P = .015) hours during swallowing in group B. The incidence and severity of hoarseness were comparable at each time-point between the 2 groups (P > .05). CONCLUSION: Preoperative inhaled budesonide combined with intravenous dexamethasone reduced the incidence and severity of POST at 6, 12, and 24 hours after extubation compared with intravenous dexamethasone alone in patients who underwent thyroidectomy. Additionally, this combination decreased the incidence of postoperative coughing at 24 hours.

ABSTRACT

BACKGROUND: Group A Streptococcus (GAS) is the predominant bacterial pathogen of pharyngitis in children. However, distinguishing GAS from viral pharyngitis is sometimes difficult. Unnecessary antibiotic use contributes to unwanted side effects, such as allergic reactions and diarrhea. It also may increase antibiotic resistance. OBJECTIVES: To evaluate the effect of a machine learning algorithm on the clinical evaluation of bacterial pharyngitis in children. METHODS: We assessed 54 children aged 2-17 years who presented to a primary healthcare clinic with a sore throat and fever over 38°C from 1 November 2021 to 30 April 2022. All children were tested with a streptococcal rapid antigen detection test (RADT). If negative, a throat culture was performed. Children with a positive RADT or throat culture were considered GAS-positive and treated antibiotically for 10 days, as per guidelines. Children with negative RADT tests throat cultures were considered positive for viral pharyngitis. The children were allocated into two groups: Group A streptococcal pharyngitis (GAS-P) (n=36) and viral pharyngitis (n=18). All patients underwent a McIsaac score evaluation. A linear support vector machine algorithm was used for classification. RESULTS: The machine learning algorithm resulted in a positive predictive value of 80.6 % (27 of 36) for GAS-P infection. The false discovery rates for GAS-P infection were 19.4 % (7 of 36). CONCLUSIONS: Applying the machine-learning strategy resulted in a high positive predictive value for the detection of streptococcal pharyngitis and can contribute as a medical decision aid in the diagnosis and treatment of GAS-P.

ABSTRACT

BACKGROUND: Post-operative sore throat (POST) has an incidence ranging from 21 to 80%. To prevent the development of POST, several pharmacological measures have been tried. Aim of this study was to compare the efficacy of preoperative zinc, magnesium and budesonide gargles in reducing the incidence and severity of POST in patients who underwent endotracheal intubation for elective surgeries. METHODS: We conducted a prospective, randomized, double-blind, controlled equivalence trial in 180 patients admitted for elective surgical procedures under general anaesthesia. Patients were randomised into three groups; group Z received 40 mg Zinc, group M received 250 mg Magnesium Sulphate and group B received 200 µg Budesonide in the form of 30 ml tasteless and colourless gargle solutions. Sore throat assessment and haemodynamic recording was done postoperatively at immediate recovery (0 h) and 2, 4, 6, 8, 12 and 24 h post-operatively. POST was graded on a four-point scale (0-3). RESULTS: POST score was comparable at all recorded time points i.e. 0,2,4,6,8,12 and 24 h. Maximum incidence was seen at 8 h in group B (33.3%) and the minimum incidence was at 24 h in group Z (10%) (p > 0.05). It was found that the incidence of POST was more in the surgeries lasting longer than 2 h in all groups. This difference was found to be statistically significant in Groups M and B. The incidence of POST was found to be comparable between laparoscopic and open procedures. CONCLUSION: Magnesium, zinc and budesonide have an equivocal effect in the prevention of POST at different time points. The incidence of sore throat increases significantly in surgeries lasting more than two hours if magnesium or budesonide have been used as premedicant. Duration of surgery is an independent predictor for POST. TRIAL REGISTRATION: CTRI/2021/05/033741 Date-24/05/2021(Clinical Trial Registry of India).

ABSTRACT

BACKGROUND: Acute tonsillopharyngitis is one of the most common types of respiratory tract infections. In case of bacterial etiologies of the disease, penicillin antibiotics are prescribed, in particular amoxicillin + clavulanic acid. Dispersible forms of antibiotics have a number of advantages over film-coated tablets and are characterized by better pharmacokinetic parameters that increase the effectiveness and safety of treatment, as well as patient compliance. AIM: To compare the effectiveness and safety of Amoxicillin + Clavulanic acid EXPRESS in the form of dispersible tablets and amoxicillin with clavulanic acid in film-coated tablets in the treatment of acute streptococcal tonsillopharyngitis. MATERIALS AND METHODS: A randomized comparative clinical study involved 60 adult patients diagnosed with acute streptococcal tonsillopharyngitis. Group 1 (n=30) received the Amoxicillin + Clavulanic acid EXPRESS, dispersible tablets, 875+125 mg 2 times a day at the beginning of meals. Group 2 (n=30) received Amoxiclav, film-coated tablets, 875+125 mg 2 times a day at the beginning of meals. The duration of the treatment was 10 days. The following procedures were performed to all participants: general clinical and otorhinolaryngological examinations, an express test to detect group A streptococcal antigens in a smear from the posterior pharyngeal wall (streptatest), assessment of symptoms of acute tonsillopharyngitis on the McIsaac scale, severity of sore throat, difficulty swallowing, swelling of the throat, measurement of body temperature, assessment of the clinical global impression of the therapy, adherence to treatment, frequency of the adverse reactions before treatment, 3 days after the beginning of therapy and after the course completion (day 10). RESULTS: Recovery occurred in 96.6% of patients in group 1 according to examination on the 10th day of treatment and in 93.3% of patients in group 2. The rate of fever regression was higher in group 1 - on the 3rd day of treatment, normalization of temperature was observed in 36.6% and 30% of patients in the comparison group. Pain syndrome, symptoms of throat swelling and difficulty swallowing significantly (p<0.01) regressed by the 10th day in patients of both treatment groups. The incidence of adverse reactions on the 10th day of treatment in group 1 was 10%, in group 2 - 33.3% (p=0.03). CONCLUSION: Amoxicillin + Clavulanic acid EXPRESS has high therapeutic efficacy in the treatment of acute streptococcal tonsillopharyngitis, comparable to the Amoxiclav in film-coated tablets. At the same time, dispersible tablets of Amoxicillin + Clavulanic acid EXPRESS demonstrated a significantly higher safety profile compared to the simple tablet form.

ABSTRACT

OBJECTIVE: Periodic fever, aphthous stomatitis, pharyngitis and adenitis (PFAPA) syndrome and familial Mediterranean fever (FMF) are autoinflammatory disorders typically characterized by recurrent fever attacks. These recurrent fever attacks can lead to depression and anxiety in mothers of these patients. This study aimed to compare the depression and anxiety levels in mothers of PFAPA and FMF patients. METHODS: This study is a cross-sectional observational study. 48 mothers of children with FMF and 70 mothers of children with PFAPA participated in the study. Mothers in these two groups were compared in terms of anxiety and depression by using the validated Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). RESULTS: Depression and anxiety scores of mothers were found to be similar in FMF and PFAPA groups. Moderate or high level of anxiety was seen in 32% of mothers of patients with PFAPA and 27% of mothers of patients with FMF. 23% of mothers of patients with PFAPA were evaluated as having moderate or severe depression, and 18% of mothers of patients with FMF were evaluated as having moderate depression. There was no statistically significant difference between the duration, frequency of attacks, recurrent hospitalizations, sociodemographic characteristics, and inventory scores. CONCLUSION: Depression and anxiety scores of mothers with children diagnosed with FMF and PFAPA are similar. These two diseases affect families psychosocially at similar levels. It is important to provide psychosocial support to families.

ABSTRACT

Our study aimed to develop a virucidal throat spray using bioactive compounds and excipients, focusing on the preparation of Curcumin (CUR) in a self-nano emulsifying drug delivery system (SNEDDS). Two molecular docking studies against SARS-CoV-2 targets guided the selection of proper oil, surfactant, co-surfactant, and natural bioactive that would maximize the antiviral activity of the throat spray. Two self-nanoemulsifying formulas that were diluted with different vehicles to prepare eight CUR-loaded SNESNS (self-nanoemulsifying self-nanosuspension) formulas. In vitro characterization studies and in vitro anti-SARS-CoV-2 effect revealed that the optimal formula, consisted of 20 % Anise oil, 70 % Tween 80, 10 % PEG 400, and 0.1 %w/w CUR, diluted with DEAE-Dx. Preclinical toxicity tests on male rats confirmed the safety of a mild throat spray dose (5 µg/mL CUR). In a rat model of acute pharyngitis induced by ammonia, post-treatment with the optimal formula of CUR loaded SNESNS for one week significantly reduced elevated proinflammatory markers (TNF-α, IL6, MCP1, and IL8). In conclusion, our CUR-loaded SNESNS formula, at 5 µg/mL concentration, shows promising effect as a prophylactic throat spray against SARS-CoV-2 and as a treatment for pharyngitis.

ABSTRACT

Streptococcus pyogenes, Group A Streptococcus (GAS), is a human pathogen that causes a spectrum of diseases from mild to severe, including GAS pharyngitis, a common acute respiratory disease in developed countries. Although wastewater-based epidemiology (WBE) has been extensively used to monitor viral pathogens such as severe acute respiratory syndrome coronavirus 2, its applicability to S. pyogenes remains unexplored. This study was conducted to investigate the feasibility of detecting and quantifying S. pyogenes in wastewater by quantitative polymerase chain reaction (qPCR) and evaluate the applicability of WBE for monitoring the prevalence of GAS pharyngitis. A total of 52 grab influent samples were collected from a wastewater treatment plant in Japan once a week between March 2023 and February 2024. The samples were centrifuged, followed by nucleic acid extraction and qPCR for the S. pyogenes-specific genes speB and spy1258. Of the 52 samples, 90 % and 81 % were positive for speB and spy1258 genes, respectively, indicating the feasibility of S. pyogenes for wastewater surveillance. However, the percentage of quantifiable samples for speB gene was significantly higher in winter than in spring and summer. Similarly, the concentrations of both genes in wastewater samples were significantly higher in winter (speB, 4.1 ± 0.27 log10 copies/L; spy1258, 4.1 ± 0.28 log10 copies/L; One-way ANOVA, p < 0.01) than in spring and summer. Higher concentrations and detection ratios of S. pyogenes genes were observed during increased GAS pharyngitis cases in the catchment. Significant moderate correlations were observed between target gene concentrations and reported GAS pharyngitis cases. This study enhances the understanding role of WBE in monitoring and managing infectious diseases within communities.

ABSTRACT

Group A beta-hemolytic streptococcal pharyngitis is a common infection responsible for more than 6 million office visits in the United States annually. Only 10% of adults seeking care for a sore throat have group A beta-hemolytic streptococcal pharyngitis; however, 60% or more are prescribed antibiotics. Guidelines recommend using clinical decision rules to assess the risk of group A beta-hemolytic streptococcal infection, followed by rapid antigen testing if a diagnosis is unclear, before prescribing antibiotics. Fever, tonsillar exudate, cervical lymphadenitis, and patient ages of 3 to 15 years increase clinical suspicion. A cough is more suggestive of a viral etiology. The limited history used in these decision rules is amenable to virtual visits. After a negative rapid antigen test result, a throat culture is recommended in children and adolescents. Penicillin and amoxicillin are first-line antibiotics, with a recommended course of 10 days; first-generation cephalosporins are recommended for patients with nonanaphylactic allergies to penicillin. There is significant resistance to azithromycin and clarithromycin in some parts of the United States. Steroids are not recommended for symptomatic treatment. Patients with worsening symptoms after appropriate antibiotic initiation or with symptoms lasting 5 days after the start of treatment should be reevaluated. Tonsillectomy is rarely recommended as a preventive measure: seven episodes of streptococcal pharyngitis in 1 year, five episodes in each of the past 2 years, or three episodes in each of the past 3 years are commonly used thresholds for considering surgery.

ABSTRACT

Among genes present in all group A streptococci (GAS), those encoding M-fibril and T-pilus proteins display the highest levels of sequence diversity, giving rise to the two primary serological typing schemes historically used to define strain. A new genotyping scheme for the pilin adhesin and backbone genes is developed and, when combined with emm typing, provides an account of the global GAS strain population. Cluster analysis based on nucleotide sequence similarity assigns most T-serotypes to discrete pilin backbone sequence clusters, yet the established T-types correspond to only half the clusters. The major pilin adhesin and backbone sequence clusters yield 98 unique combinations, defined as "pilin types." Numerous horizontal transfer events that involve pilin or emm genes generate extensive antigenic and functional diversity on the bacterial cell surface and lead to the emergence of new strains. Inferred pilin genotypes applied to a meta-analysis of global population-based collections of pharyngitis and impetigo isolates reveal highly significant associations between pilin genotypes and GAS infection at distinct ecological niches, consistent with a role for pilin gene products in adaptive evolution. Integration of emm and pilin typing into open-access online tools (pubmlst.org) ensures broad utility for end-users wanting to determine the architecture of M-fibril and T-pilus genes from genome assemblies.IMPORTANCEPrecision in defining the variant forms of infectious agents is critical to understanding their population biology and the epidemiology of associated diseases. Group A Streptococcus (GAS) is a global pathogen that causes a wide range of diseases and displays a highly diverse cell surface due to the antigenic heterogeneity of M-fibril and T-pilus proteins which also act as virulence factors of varied functions. emm genotyping is well-established and highly utilized, but there is no counterpart for pilin genes. A global GAS collection provides the basis for a comprehensive pilin typing scheme, and online tools for determining emm and pilin genotypes are developed. Application of these tools reveals the expansion of structural-functional diversity among GAS via horizontal gene transfer, as evidenced by unique combinations of surface protein genes. Pilin and emm genotype correlations with superficial throat vs skin infection provide new insights on the molecular determinants underlying key ecological and epidemiological trends.

ABSTRACT

BACKGROUND: Reducing antibiotic use in Australia, and the subsequent impact on antimicrobial resistance, requires multiple, sustained approaches with appropriate resources and support. Additional strategies to reduce antibiotic prescribing include effective vaccines, against pathogens such as Streptococcus pyogenes, the most common bacterial cause of sore throat. As part of efforts towards assessing the benefits of introducing new strategies to reduce antimicrobial prescribing, we aimed to determine the burden of antimicrobial prescribing for sore throat in general practice. METHODS: General practice activity data from 2013 - 2017 derived from the first 8 practices participating in the 'Primary Care Audit, Teaching and Research Open Network' (Patron) program were analysed according to reason for visit (upper respiratory tract infection, URTI, or sore throat) and antibiotic prescription. The main outcome measures were percentage of sore throat or URTI presentations with antibiotic prescription by age. RESULTS: A total of 722,339 visits to general practice were made by 65,449 patients; 5.7% of visits were for URTI with 0.8% meeting the more specific criteria for sore throat. 66.1% of sore throat visits and 36.2% of URTI visits resulted in antibiotic prescription. Penicillin, the recommended antibiotic for sore throat when indicated, was the antibiotic of choice in only 52.9% of sore throat cases prescribed antibiotics. Broader spectrum antibiotics were prescribed more frequently in older age groups. CONCLUSIONS: Frequency of antibiotic prescribing for sore throat is high and broad, despite Australian Therapeutic guideline recommendations. Multiple, sustained interventions to reduce prescribing, including availability of effective S. pyogenes vaccines that could reduce the incidence of streptococcal pharyngitis, could obviate the need to prescribe antibiotics and support ongoing efforts to promote antimicrobial stewardship.

ABSTRACT

OBJECTIVE: The present study aimed to compare the effect of topical laryngeal lidocaine with intravenous lidocaine before endotracheal intubation on the incidence and severity of postoperative sore throat, hoarseness, and cough. PATIENTS AND METHODS: This prospective randomized controlled study enrolled 144 patients undergoing laparoscopic cholecystectomy with endotracheal intubation. The patients were randomized to three groups and received 2% lidocaine by topical laryngeal spray (group T), intravenous 2% lidocaine (group I), and the equivalent volume of intravenous saline (group C) before intubation. The incidence and severity of sore throat, hoarseness, and cough reaction at 0.5, 1, 6, and 24 h after extubation were collected. RESULTS: The incidence of sore throat was significantly lower in group T than in groups I and C (6.4% vs. 37.2% and 86.7%, p < 0.001), respectively at 0.5 h after extubation, and it was significantly lower in group I than that in group C (37.2% vs. 86.7%, p < 0.001). Both the incidence of hoarseness and cough were significantly lower in group T than in group I and in group C (14.9% vs. 97.7% and 97.8%, p < 0.001, and 19.1% vs. 72.0% and 93.3%, p < 0.001), respectively. The severity of sore throat, hoarseness and cough in group T was significantly lower than that in group I and that in group C (p < 0.05), and it was significantly lower in group I than in group C (p < 0.05). CONCLUSIONS: Both topical laryngeal lidocaine and intravenous lidocaine before intubation have positive effects on preventing sore throat. Topical laryngeal route was superior to intravenous route.

ABSTRACT

Anxiety is a remarkably common condition among patients with pharyngitis, but the relationship between these disorders has received little research attention, and the underlying neural mechanisms remain unknown. Here, we show that the densely innervated pharynx transmits signals induced by pharyngeal inflammation to glossopharyngeal and vagal sensory neurons of the nodose/jugular/petrosal (NJP) superganglia in mice. Specifically, the NJP superganglia project to norepinephrinergic neurons in the nucleus of the solitary tract (NTSNE). These NTSNE neurons project to the ventral bed nucleus of the stria terminalis (vBNST) that induces anxiety-like behaviors in a murine model of pharyngeal inflammation. Inhibiting this pharynx→NJP→NTSNE→vBNST circuit can alleviate anxiety-like behaviors associated with pharyngeal inflammation. This study thus defines a pharynx-to-brain axis that mechanistically links pharyngeal inflammation and emotional response.

ABSTRACT

Background: This study examined the epidemiological correlations between secretory otitis media (SOM) and diseases of neighboring organs. We measured changes in disease incidences during the 2020 COVID-19 pandemic using Internet big data spanning from 2011 to 2021. Methods: This study used the Baidu Index (BI) to determine the search volume for the terms "secretory otitis media (SOM)", "tonsillitis", "pharyngolaryngitis", "adenoid hypertrophy (AH)", "nasopharyngeal carcinoma (NPC)", "nasal septum deviation (NSD)", "rhinosinusitis", "allergic rhinitis (AR)", and "gastroesophageal reflux disease (GERD)" in Mandarin from January 2011 to December 2021. The correlations between these terms were analyzed using Spearman's correlation coefficients. The results were compared search data from 2019 and 2021 to assess the effects of isolation on SOM in 2020. Results: The seasonal variations trends of SOM and other diseases coincided well (P < 0.05), except for AR. During the 11-year timeframe, the monthly searches for rhinosinusitis, NSD, tonsillitis, pharyngolaryngitis, and NPC were statistically correlated with SOM (R = 0.825, 0.594, 0.650, 0.636, 0.664, respectively; P < 0.05). No correlation was found between SOM and AR, SOM and AH, or SOM and GERD (R =  - 0.028, R = 0.259, R = 0.014, respectively, P > 0.05). The total search volumes for SOM, rhinosinusitis, NPC, and AH decreased in 2020 compared to 2019. Discussion: SOM exhibited a discernible epidemiological connection with rhinosinusitis, nasal septal deviation (NSD), tonsillitis, pharyngolaryngitis, and nasopharyngeal carcinoma (NPC). A decrease in public gatherings was observed to effectively reduce the incidences of SOM. This underscores the pivotal role of social measures in influencing the prevalence of SOM and emphasizes the intricate interplay between SOM and various associated health factors, with implications for public health strategies.

ABSTRACT

Group A Streptococcus causes a variety of clinical manifestations, including pharyngitis and skin and soft tissue infections as well as more invasive disease. There are also multiple nonsuppurative complications of group A Streptococcus infection, including acute rheumatic fever and poststreptococcal glomerulonephritis. Pediatricians should be able to diagnose and treat the various presentations of the infection.

ABSTRACT

STUDY OBJECTIVE: Postoperative sore throat (POST) and hoarseness are common complications of tracheal intubation. This study aims to evaluate the efficacy of flurbiprofen administered through the subglottic port of tracheal tubes to prevent POST after cardiac surgery. DESIGN: Single-center, prospective, randomized, double-blind, placebo-controlled trial. SETTING: Tertiary Care Referral University Hospital (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome). PATIENTS: Included 71 patients undergoing for elective cardiac surgery. Inclusion criteria were (a) age between 50 and 75 years, (b) NYHA class I or II, (c) surgery for myocardial revascularization or valve repair or replacement under cardiopulmonary bypass. INTERVENTION: Patients were double blind randomized to receive flurbiprofen or saline in the subglottic port of the endotracheal tube (groups F and P). The solution was injected ten minutes after tracheal tube placement, ten minutes after ICU admission and ten minutes before tracheal tube removal. MEASUREMENTS: The primary outcome was to assess the effect of topical flurbiprofen administered through the subglottic port of the tracheal tube to prevent post-operative sore throat (POST). The secondary outcomes were the presence of hoarseness safety and patient's subjective satisfaction with their recovery. We did not report any exploratory outcomes. MAIN RESULTS: We analyzed 68 patients, 34 patients in each group. In group F, two patients complained of POST and hoarseness (5.9%), while all controls did. The two groups significantly differed in the severity scores (VAS and TPS for sore throat and HOAR for hoarseness) at all time points. In group P, patients reported mild to moderate symptoms that significantly improved or disappeared 36 h after tracheal tube removal. According to the multivariable model, hoarseness affected women less than men, in the control group (p = 0.002). None of the patients in either group reported any adverse effects. CONCLUSIONS: Repeated administration of flurbiprofen through the subglottic port of tracheal tubes reduced the incidence of sore throat and hoarseness after cardiac surgery without evidence of complications.
