Self-reported health effects from wildfire smoke: A cross-sectional study in New York State

Abstract Background Wildfires and exposure to wildfire smoke (WFS) are forecasted to increase, in part driven by climate change. As witnessed in 2023, regions in Europe and North America are facing more sustained periods of poor air quality due to WFS. Growing evidence suggests average daily WFS correlates with morbidity and mortality, but the impact of prolonged WFS exposure remains understudied, especially in areas where WFS is a newer occurrence. We examine associations between consecutive days of WFS experienced and self-reported health symptoms in the northeastern United States. Methods This retrospective cross-sectional study explored New York State (NYS) residents’ experience with WFS in summer 2023 via an online survey. Participants reported the longest period of consecutive WFS days and symptoms experienced. Log-binomial regression models estimated prevalence ratios (PR) and 95% confidence intervals (CI). Results 553 NYS residents were included, representing a healthy, primarily female and White population, ranging from 18 to 86 years. 549 (99.3%) reported experiencing WFS, with the longest period of consecutive WFS days varying (≤3 days: n = 152; 4 to 6 days: n = 255; ≥7 days: n = 146). 490 (88.6%) reported ≥1 health symptom, with itchy/watery eyes, sore throat, and headache as the most frequent. Compared to ≤ 3 consecutive WFS days, symptom prevalence was 9.1% higher for those reporting 4 to 6 days (PR [95% CI]:1.09 [1.00, 1.19]) and 16.7% higher for ≥7 days (1.17 [1.07, 1.27]). The trend of increased symptom prevalence with longer WFS periods persisted and was pronounced for specific symptoms. Control for potential confounders did not appreciably change estimates. Conclusions Our findings suggest longer sustained WFS exposure associates with higher symptom prevalence, which may be precursors to more serious health conditions. As global populations face more WFS with climate change, public health professionals should prioritize strategies to mitigate prolonged exposure. Key messages • In a convenience sample of 553 primarily healthy New York State residents, 99.3% reported experiencing wildfire smoke and 88.6% reported at least 1 symptom of poor health during summer 2023. • Associations between consecutive days of wildfire smoke experienced and prevalence of any and specific symptoms tended to vary in a dose-response manner.

Clinical characteristics and distinguishing factors of patients with COVID-19 complicated with active pulmonary tuberculosis.

The current study was conducted aimed at exploring the clinical characteristics and distinguishing factors of patients with the novel coronavirus pneumonia (COVID-19) complicated with active pulmonary tuberculosis. A total of 354 patients with COVID-19 in our hospital from November 2022 to February 2023 were included in the present study, of whom 87 patients were also combined with active pulmonary tuberculosis. Significant differences were found in fever, fatigue, nasal congestion, nasal discharge, sore throat, expectoration, and weight loss between the two groups (p < 0.05). There were significant differences in the levels of leukocyte, neutrophil, lymphocyte count, monocyte, hemoglobin, C-reactive protein, and CD4/CD8 between the two groups (p < 0.05). There were significant differences in pulmonary consolidation, multifocal ground-glass opacities in both lungs and infiltrating shadows, "cavity" by CT imaging between the two groups (p < 0.05). The independent variables were set as the indicators with different results of clinical characteristics and CT imaging, including fever, fatigue, nasal congestion, nasal discharge, sore throat, expectoration, weight loss, leukocytes, count neutrophils and lymphocytes, monocytes, hemoglobin, C-reactive protein, CD4/CD8, pulmonary consolidation, multifocal ground-glass opacities in both lungs and infiltration shadows. Our findings have revealed that fever, fatigue, expectoration, leukocytes, neutrophils, monocytes, hemoglobin, C-reactive protein, lymphocytes, CD4/CD8, pulmonary consolidation, multifocal ground-glass opacities in both lungs, and infiltration shadows were the risk factors responsible for the patients with COVID-19 complicated with active pulmonary tuberculosis.

The effect of COVID-19 vaccination on symptomatic infection and related symptoms among preterm-born children aged 3–7 years in China

Vaccination plays a crucial role in preventing and controlling SARS-CoV-2 infections as well as their associated adverse outcomes. But there is a notable lack of research on the effectiveness of COVID-19 vaccination in children, particularly those young preterm-born children, who are more vulnerable to severe outcomes from SARS-CoV-2 infection. We aimed to determine the effect of vaccination with inactivated vaccines BBIBP-CorV and CoronaVac on symptomatic COVID-19 infection and related symptoms in preterm-born children aged 3–7 years after relaxation of the COVID-19 prevention and control measures in December 2022 in China. We performed a retrospective cohort study involving 242 preterm-born children aged 3–7 years and the data were collected in March 2023. Logistic regression models and modified Poisson regression models combined with entropy balancing were used to explore the associations of vaccination against SARS-CoV-2 with symptomatic COVID-19, specific symptoms, and persistent symptoms one month after recovery from COVID-19. Of the 242 recruited preterm-born children, 156 (64.5%) were vaccinated with inactivated vaccines BBIBP‐CorV and CoronaVac. After entropy balancing, the covariates were balanced between the vaccinated and the unvaccinated groups, with standardized mean difference < 0.001. Vaccination with the said SARS-CoV-2 vaccines lowered the risk of developing symptomatic COVID-19 in preterm-born children (risk ratio [RR] = 0.783; 95% confidence interval [CI]: (0.711, 0.861). Likewise, COVID-19 vaccination was associated with a decline in the risk of pneumonia (odds ratio [OR] = 0.318; 95% CI 0.110, 0.913), fever (RR = 0.710; 95% CI 0.635, 0.794), high fever (RR = 0.542; 95% CI 0.297, 0.988), sore throat (OR = 0.304; 95% CI 0.139, 0.664), and persistent symptoms (RR = 0.425; 95% CI 0.182, 0.993). Immunization with inactivated vaccines BBIBP‐CorV and CoronaVac provides protection against symptomatic COVID-19 for preterm-born children 3–7 years.

Acute Ear, Nose and Throat Pain in Children in Brazzaville

Objective: To evaluate the intensity of acute pain associated with ENT conditions during consultations and the effectiveness of the analgesic prescribed. Patients and Methods: We conducted a prospective, experimental, randomised, double-blind study in the ENT CCF department of the CHUB. The study took place over a period of 9 months (01 March to 30 November 2021) and involved only children aged 2-12 years presenting with an acute ENT complaint and having been treated in the ENT consultation department of the CHUB. Paracetamol and ibuprofen were administered after pain assessment. Results: During the study period, 60 patients presented with acute ENT complaints and were managed on an outpatient basis. The mean age was 7.7 +/- 31 years, with extremes ranging from 2 to 12 years. Tekes were the most represented ethnic group at 58.4%. Schoolchildren represented the most common school level. Acute pain affected patients' life activities. Acute pharyngitis was the most common pathology. Acute ENT pain. Paracetamol and ibuprofen were the molecules most frequently used, and pain was virtually absent on the 3rd day of use (96.7% and 75% respectively for paracetamol and ibuprofen). Conclusion : Acute pain in children is often underestimated or sometimes inadequately treated.

Analysis of the efficacy of vocal cord botulinum toxin injection for refractory laryngeal contact granuloma

Objective: To observe the efficacy of vocal cord botulinum toxin type A injection in the treatment of refractory laryngeal contact granuloma and to analyze the factors affecting the curative effect. Methods: Fifty-two patients with refractory laryngeal contact granuloma who received vocal cord botulinum toxin type A injection under topical anesthesia from May 2021 to May 2023 were analyzed retrospectively. Among them, 51 were males and 1 was female, aged 22-66 (48.98±8.87)years old. All patients were followed up for a minimum of 12 months. Outcome measures in terms of patient cure rate, total effective rate, complications and recurrence rate were calculated. The median [M (Q1, Q3)] was used to represent non-normally distributed measurement data, and Logistic regression analysis was used to determine independent risk factors affecting efficacy. Results: The cure rate of 52 patients with refractory laryngeal contact granuloma treated by vocal cord botulinum toxin type A injection was 78.8% (41/52), and the total effective rate (including cure, marked and effective) was 90.4% (47/52). The median number of injections was 1[1,2]. Following a single injection, the cure rate was 69.2% (36/52), and the median treatment duration for cured patients was 3 [3,3] months. Hoarseness occurred in 88.5% (46/52) of patients, with recovery within 3 months in all cases. Additionally, 21.2% (11/52) of the patients experienced cough, sore throat, dyspnea, all of whom recovered within 3 months. One patient among the 41 cured cases was lost to follow-up, and the recurrence rate at the 12th month was 17.5% (7/40). Multivariate regression analysis indicated that age, granuloma size, history of PPI treatment, previous corticosteroid injections, prior surgical excision, pharyngeal reflux, chronic cough, pharyngeal reflux, chronic cough and vocal overuse were not independent risk factors for cure and recurrence. Conclusion: Vocal cord botulinum toxin type A injection is an alternative for the treatment of refractory laryngeal contact granuloma, which offers benefits such ashigh cure rate, short treatment cycle and less injection times.

Review: Current Laboratory and Point-of-Care Pharyngitis Diagnostic Testing and Knowledge Gaps.

Pharyngitis is an inflammatory condition of the pharynx and/or tonsils commonly seen in both children and adults. Viruses and bacteria represent the most common encountered etiologic agents-yeast/fungi and parasites are infrequently implicated. Some of these are predominantly observed in unique populations (eg, immunocompromised or unvaccinated individuals). This manuscript (part 2 of 3) summarizes the current state of laboratory and point-of-care diagnostic testing and highlights the expanding role of nucleic acid amplification in the expedited diagnosis and management of patients with acute pharyngitis. It discusses preanalytical, analytical, and postanalytical variables that impact the performance of culture, rapid antigen, and nucleic acid amplification testing. Finally, it sets the stage for part 3, which discusses the emerging role of biomarkers in the management of individuals with acute pharyngitis.

Epidemiology of human metapneumovirus in Taiwan from 2013 to 2023

Human metapneumovirus (HMPV) is a member of the genus Metapneumovirus in the family Pneumoviridae of the order Mononegavirales that can cause upper and lower respiratory tract disease. This retrospective study describes the epidemiology of hMPV based on community viral surveillance results from sentinel sites across Taiwan from 2013 to 2023. A total of 114 hMPV strains were isolated and analyzed to assess viral evolution through sequencing of their fusion protein genes. This study revealed that hMPV cases occur almost year-round in Taiwan, with a peak occurring during spring (March to May). Of the 114 infected patients, 68.4% were children under 4 years old. The geographical distribution of hMPV positivity was highest in Penghu County, followed by Changhua County and Hsinchu County. The clinical symptoms of hMPV infection are nonspecific, with fever (56.1%), cough (44.7%), rhinorrhea (21.1%), and sore throat (14.9%) being the most common. However, a few patients also developed severe central nervous system symptoms (1.8%) or dyspnea (0.9%). Phylogenetic analysis revealed genetic diversity among the 114 isolated hMPV strains, with the A2 lineage (57.9%) being the most frequently observed, followed by the B2 lineage (33.3%), in the Taiwanese community from 2013 to 2023. In conclusion, hMPV causes a serious acute respiratory disease in Taiwan that should not be neglected. Further epidemiological surveillance and investigations of the clinical characteristics of hMPV should be performed continually for prevention and control of this virus.

Review: Known, Emerging, and Remerging Pharyngitis Pathogens.

Pharyngitis is an inflammatory condition of the pharynx and/or tonsils commonly seen in both children and adults. Viruses and bacteria represent the most common encountered etiologic agents-yeast/fungi and parasites are infrequently implicated. Some of these are predominantly observed in unique populations (eg, immunocompromised or unvaccinated individuals). This article (part 1 of 3) summarizes the impact of acute pharyngitis on the health care system and reviews the etiologic agents of acute pharyngitis, including both emerging and reemerging pathogens that health care providers should consider when evaluating their patients. Finally, it sets the stage for parts 2 and 3, which discuss the current and evolving state of diagnostic testing for acute pharyngitis.

Review: Diagnostic Potential for Collaborative Pharyngitis Biomarkers.

Pharyngitis is an inflammatory condition of the pharynx and/or tonsils commonly seen in both children and adults. Viruses and bacteria represent the most common encountered etiologic agents-yeast/fungi and parasites are infrequently implicated. Some of these are predominantly observed in unique populations (eg, immunocompromised or unvaccinated individuals). This manuscript (part 3 of 3) summarizes the current state of biomarker diagnostic testing and highlights the expanding role they will likely play in the expedited diagnosis and management of patients with acute pharyngitis. Biomarkers, in conjunction with rapid antigen and/or nucleic acid amplification testing, will likely become the standard of care to accurately diagnose the etiologic agent(s) of pharyngitis. This novel testing paradigm has the potential to guide appropriate patient management and antibiotic stewardship by accurately determining if the cause of pharyngitis is due to a viral or bacterial etiology.

Rapid and precise identification of cervicothoracic necrotizing fasciitis caused by Prevotella and Streptococcus constellatus by using Nanopore sequencing technology: a case report

IntroductionCervicothoracic necrotizing fasciitis (CNF) is one form of necrotizing soft-tissue infections, which could lead to patient demise during short course. Therefore, early recognition and immediate treatment contribute to promising prognosis of patients.Case presentationA 58-year-old diabetic patient presented with a sore throat and progressive irritation of the neck and chest for 4 days. The initial diagnosis was considered to be soft-tissue infection and the clinician gave empirical anti-infectious medication for expectant treatment. During the course of disease, surgical incision was performed to relieve suffocation and shortness of breath. The drainage fluids were detected with microbiological culture and molecular sequencing. Nanopore sequencing technology (NST) helped to identify the coinfection of Streptococcus constellatus and Prevotella spp., which was not recognized during the original period of 15 days. The precise identification of pathogen supported to guide the pharmacologic treatment with meropenem and linezolid. Ultimately, combined with the surgical observation and post-surgical pathological examination, the patient was diagnosed as CNF, which could be much more acute and serious than normal soft-tissue infections. The patient has been successfully treated with prompt antimicrobial medication and appropriate surgical debridement.ConclusionThis case presented a CNF patient with type 2 diabetes, successfully recovered after prompt microbial detection, precise anti-infectious treatment, and appropriate surgical intervention. It highlights the importance of recognizing pathogen by applying rapid microbiological detection, including NST, in acute and serious infectious disease.

Epidemiology, presentation, management and outcomes of patients with acute epiglottitis - A 10-year retrospective study based on a tertiary hospital in northern China.

This study aimed to explore the new clinical characteristics and trends of acute epiglottitis (AE) in northern China. A retrospective, observational study was conducted on patients diagnosed with AE between January 2014 and December 2023 at a single-center medical institution in northern China. The clinical profiles of patients with AE were investigated. This study encompassed 366 AE patients (M: F = 1.79:1). The average age of the patients was 47.31 ± 13.18 years, and 33.4% patients had comorbidities. Common initial symptoms: sore throat (93.17%), dysphagia (48.09%), fever (10.65%). Dyspnea reported in 14.48%. AE incidence rose annually over a decade, with mild seasonal variations.Laryngoscopy remains the primary means of confirming AE. Almost all patients received intravenous antibiotic therapy, and 98% of them were also treated with corticosteroids. Emergency airway intervention needed in 2.73% (cricothyroidotomy: 0.54%; tracheotomy: 2.19%). Among all patients, 353 (96.44%) had a good prognosis, 1 death (0.27%) from cardiopulmonary arrest during tracheotomy, 1 anoxic encephalopathy (0.27%) after tracheotomy in the emergency room due to intubation failure. The incidence rate of AE is on the rise. Even if airway intervention is rarely required, clinicians must maintain a high degree of vigilance and conduct early identification of risk factors and emergencies that could progress severe cases into life-threatening. Furthermore, the development of safe and efficacious management strategies is crucial to prevent catastrophic complications and safeguard patient lives.

Endotracheal Tube Cuff Deflation Methods Reduce Stress Response and Incidence of Postoperative Pharyngeal Complications in Patients Treated with Gynecological Laparoscopic Surgery.

This study aims to explore the impact of endotracheal tube cuff deflation methods on extubation stress responses and postoperative pharyngeal complications in patients treated with gynecological laparoscopic surgery. In this study, retrospective clinical data of 94 patients treated with gynecological laparoscopic surgery under general anesthesia in Northwest Women's and Children's Hospital from June 2023 to June 2024 were collected and analyzed. Patients were assigned into two groups based on the cuff deflation methods used after anesthesia: Group A (45 patients) adopted a one-time deflation method, while Group B (49 patients) employed a gradual deflation method. Surgery-associated indicators were recorded, with heart rate (HR), mean arterial pressure (MAP), rate pressure product (RPP), epinephrine (E), norepinephrine (NE), and cortisol (Cor) levels monitored at selected time points: before cuff (T0), immediately after extubation (T1), 1 minute post-extubation (T2), 5 minutes post-extubation (T3), and 10 minutes post-extubation (T4). The incidence of pharyngeal complications was also compared between the two groups. Compared with Group A, Group B displayed smaller variations in HR, MAP, and RPP at T1, T2, and T3 (p < 0.05). Group B also showed smaller variations in E, NE, and Cor levels at T2, T3, and T4 in contrast with Group A (p < 0.05). The incidence of complications such as coughing, sore throat, and hoarseness was conspicuously attenuated in Group B compared to Group A (6.12% vs 22.22%, p < 0.05). Gradual deflation of the endotracheal tube cuff dramatically ameliorates extubation stress responses, stabilizes hemodynamics, and alleviates pharyngeal discomfort in patients treated with gynecological laparoscopic surgery.

Immunity and Coagulation in COVID-19.

Discovered in late 2019, the SARS-CoV-2 coronavirus has caused the largest pandemic of the 21st century, claiming more than seven million lives. In most cases, the COVID-19 disease caused by the SARS-CoV-2 virus is relatively mild and affects only the upper respiratory tract; it most often manifests itself with fever, chills, cough, and sore throat, but also has less-common mild symptoms. In most cases, patients do not require hospitalization, and fully recover. However, in some cases, infection with the SARS-CoV-2 virus leads to the development of a severe form of COVID-19, which is characterized by the development of life-threatening complications affecting not only the lungs, but also other organs and systems. In particular, various forms of thrombotic complications are common among patients with a severe form of COVID-19. The mechanisms for the development of thrombotic complications in COVID-19 remain unclear. Accumulated data indicate that the pathogenesis of severe COVID-19 is based on disruptions in the functioning of various innate immune systems. The key role in the primary response to a viral infection is assigned to two systems. These are the pattern recognition receptors, primarily members of the toll-like receptor (TLR) family, and the complement system. Both systems are the first to engage in the fight against the virus and launch a whole range of mechanisms aimed at its rapid elimination. Normally, their joint activity leads to the destruction of the pathogen and recovery. However, disruptions in the functioning of these innate immune systems in COVID-19 can cause the development of an excessive inflammatory response that is dangerous for the body. In turn, excessive inflammation entails activation of and damage to the vascular endothelium, as well as the development of the hypercoagulable state observed in patients seriously ill with COVID-19. Activation of the endothelium and hypercoagulation lead to the development of thrombosis and, as a result, damage to organs and tissues. Immune-mediated thrombotic complications are termed "immunothrombosis". In this review, we discuss in detail the features of immunothrombosis associated with SARS-CoV-2 infection and its potential underlying mechanisms.

Knowledge and Attitude of self-medication with leftover antibiotics in Saudi Arabia: A cross-sectional study

Background Antimicrobial resistance is increasing at an alarming rate. The use of antibiotics without a prescription by a patient or other family members and their inappropriate storage have caused serious health issues as it would lead to antibiotic resistance and exposure to the risk of harmful adverse effects unnecessarily. Therefore, the study aimed to evaluate the current behaviour of antibiotic usage, storage, re-usage and misuse among the residents of Saudi Arabia. Methods This is a cross-sectional study. Our target study population was the residents of Saudi Arabia. Data were collected by an online questionnaire and analysed by SPSS. Results A total of 738 participants answered the online questionnaire from all ages, genders, nationalities, and socioeconomic backgrounds residing in different regions across the Kingdom of Saudi Arabia. 76.42% knew that an antibiotic is a chemical substance used to treat infections. The participants were questioned about when they started using antibiotics, to which 95.66% (n=706) responded after consulting a physician, 3.25% (n=24) said when they felt ill for any reason, and 1.08% (n=8) replied after first attempting herbal medicine. A total of 147 participants admitted that they store excess pills of antibiotics after being prescribed for an infection and reuse them later on for symptoms like sore throat and fever. Conclusions The results indicated that nearly half of the participants used leftover antibiotics. Participants having children in their homes significantly reuse antibiotics. However, one-third of the participants didn’t complete the antibiotics course. A large portion of the population, regardless of age, level of education, or professional background, have continued to store leftover antibiotics after an infection treatment and reuse them once they think they need them for new symptoms. This advice further revises the current measures to fill those gaps and reduce this habit.

CD5+ Large B cell lymphoma with IRF4 rearrangement: case report and review of the literature

Abstract Introduction/Objective Large B cell lymphoma with IRF4 rearrangement was introduced as a diagnosis by WHO in 2017. It is a rare entity that affects Waldeyer’s ring in mostly males, children and young adults. The lesional immunophenotype may be positive for CD10. FISH is positive for IRF4 rearrangement on chromosome 6p25.Among reported cases in the English literature only 6 cases have reported specifically CD5 being negative. We present review of the literature during years 2020-2024, and a case of large B cell lymphoma with IRF4 rearrangement, specifically positive for CD5. Methods/Case Report The patient is a 5 years old male, since 2017 suffering from recurring ear infections with approximately 4-5 episodes of otitis media during every 6 months. In 2019 the patient’s mother reported snoring, constant sore throat, bad breath for 2 years. On physical examination the left tonsil appeared enlarged; exudative tonsillitis was present. Later on, an asymmetric, firm mass in the location of the left tonsil with induration of the left palate was identified. CT scan showed mild asymmetric soft tissue thickening of the left aspect of the soft palate and left palatine tonsil. Mildly prominent left-sided levels IIa and IIb lymph nodes, measuring up to 1 cm were identified. H&amp;E sections revealed an expansile proliferation of neoplastic cells, large with void to indented nuclei, vesicular chromatin, small nucleoli, visible cytoplasms. Frequent mitoses, apoptosis and individual cell necrosis were seen. Immunohistochemistry revealed CD20+ B cell neoplasm with high expression for MUM1 and high proliferation rate along with strong CD5+ and CD10-. By multicolor flow cytometric studies, an abnormal B cell population was found (40%) with increased forward scatter along with expression for CD5, CD19, CD20, CD22, CD45, CD79a (cytoplasmic), FMC7, (dim) lambda-restriction. Fluorescence In Situ Hybridization Study revealed IRF4 (DUSP22) rearrangement on chromosome 6p25. Results (if a Case Study enter NA) NA Conclusion We analyzed 24 cases reported in the English literature. The mean age of the patients is 7 years old. The majority are males (14/24 = 58%).The most common location is tonsil/ neck mass (15/24 = 62%).CD5 was negative in 6/24 cases.

The association between smoking/vaping habits and self-reported respiratory symptoms.

Smoking is well known for its harmful effect on the respiratory system, but whether vaping is less harmful is unknown. Therefore, the aim of this study was to assess the association of smoking/vaping habits with self-reported respiratory symptoms in vapers and cigarette smokers. An online survey was developed and shared on different vaping and smoking social media platforms and communities. Out of the 891 respondents, 788 were vapers (77 pure vapers and 711 ex-smokers) and 103 were cigarette smokers. Smokers reported more frequently respiratory symptoms such as chest pain, wheezing and whistling, sputum production, cough, dry mouth, and smokers suffered from more shortness of breath, sore throat and disturbed sleep compared to vapers. The self-reported respiratory symptoms in vapers were mainly related to the nicotine strength of the product and number of puffs per use. There were no significant differences between pure vapers and vapers who were ex-smokers. Self-reported severe respiratory symptoms were less frequent in vapers than smokers, irrespective of their smoking history. This suggests that vaping is less harmful than cigarette smoking.

Dispensing antibiotics without a prescription in Various pharmacies

Background: An important factor that leads to improper antibiotic use and an increase in antibacterial resistance is the dispensing of medicines over-the-counter. Objective: The purpose of this study is to examine the beliefs and behaviors of medical staff regarding the non-prescription dispensing of antibiotics. Methods: This is a cross-sectional study that used a questionnaire survey with 107 medical staff members from various places in Iraq between November 11, 2020, and May 8, 2021. Results: A total of 107 participants filled out the form and took part in the study. The age of participants ranged from 68% (21–25 years old) to 20% (26–35 years old), 4% (18–20 years), 4% (36–45 years old), 3% (above 55 years old), and 1% (46–55). The most prevalent condition treated with antibiotics without a doctor's prescription is urinary tract infection (21.6%), which was followed by otitis media (17.3%), sore throat (14.8%), skin infection (12.7%), fever (12%), cough (11%), runny nose (4.9%), and other conditions (5.7%). Cold and flu are the most infections that did not respond to antibiotics (30.1%) followed by runny nose (23.9%), sore throat (15.4%), bronchitis (10.4%), cough (10%), and other (10%) while the most frequently dispensed antibiotics was amoxicillin followed by azithromycin, amoxicillin plus clavulanic acid, ciprofloxacin, cephalexin, clindamycin, and meropenem. About 56.6% of patients requested or received antibiotics for obvious infections. About 29.25% requested antibiotics for family members while 14.15% requested them for no reason. The most common age of patients who request an antibiotic was young people (46.3%), elderly (38.3%) and children (15.4%). Whether consulting a doctor before dispensing antibiotics, participants answered yes (56%) and no (44%). In conclusion, the incidence of using antibiotics without prescription was high for skin infections, otitis media, sore throats, and urinary tract infection.

Novel Diagnostic Approach for Acute Pharyngitis: Combining Machine Learning With Thermal Imaging.

We evaluated the effect of infrared thermography (IRT) on the clinical assessment of bacterial and viral pharyngitis and its impact on the predictive value of the McIsaac score algorithm for streptococcal pharyngitis in children. We also investigated if IRT could distinguish between bacterial and viral pharyngitis. The study included children aged 2-17 years presenting with sore throat and fever over 38°C from November 1, 2021, to April 30, 2022. Of the 76 assessed children, 16 were excluded due to missing data or technical issues, leaving 60 children (32 males, 28 females) divided into three groups: Group A with streptococcal pharyngitis (N = 30), viral pharyngitis (N = 16), and healthy controls (N = 14). McIsaac score and IRT imaging showed a 90% positive predictive value for streptococcal pharyngitis. While IRT alone could not distinguish between bacterial and viral infections, it significantly increased the predictive value when combined with the McIsaac score.
