A Clinical Approach to Tonsillitis, Tonsillar Hypertrophy, and Peritonsillar and Retropharyngeal Abscesses

Inappropriate prescribing contributes to high antibiotic exposure in young children in Australia

BACKGROUND

Antibiotic exposure increases antimicrobial resistance and has also been associated with long-term harms, including allergies, inflammatory diseases and weight gain. We assessed antibiotic exposure in the first 2 years of life in Australian children, the factors influencing this and its appropriateness.

METHODS

Data from 1201 participants in the MIS BAIR randomized controlled trial were used. Multivariable logistic regression was used to identify factors associated with antibiotic exposure.

RESULTS

At 1 and 2 years of age, exposure to at least one course of antibiotics was 43% and 67%, with the highest first antibiotic prescription rate between 9 and 18 months. Amoxicillin was the most frequently used antibiotic (59%), followed by cefalexin (7%). The most common diagnoses for which antibiotics were prescribed were respiratory tract infections from 0 to 6 months of age and otitis media from 6 to 12 months. Factors associated with antibiotic exposure from 0 to 12 months of age were delivery by Caesarean section (adjusted odd-ratio (aOR) 1.5, 95%CI 1.1-1.9), birth in winter (aOR 1.7, 95%CI 1.2-2.4), maternal antibiotic exposure during the last trimester of pregnancy (aOR 1.6, 95%CI 1.1-2.3), cessation of breastfeeding by 6 months of age (aOR 1.5, 95%CI 1.1-2.0) and day-care attendance (aOR 1.4, 95%CI 1.1-1.8). Based on parent-reported questionnaires, 27% of infants were treated in the first year of life for conditions unlikely to need antibiotic treatment.

CONCLUSION

At least two-thirds of children were prescribed antibiotics in the first 2 years of life, and more than a quarter of these exposures may have been unnecessary.

Tonsillitis and Sinusitis: A Narrative Review of Pathogenesis, Diagnosis, and Management

The review aims for a comprehensive examination of tonsillitis and sinusitis, covering their pathophysiology, diagnosis, and management, with a focus on recent breakthroughs and therapeutic practices. Tonsillitis, marked by inflammation of the tonsils, can result from viral or bacterial infections, particularly Streptococcus pyogenes, with attention to antibiotic resistance trends. This review discusses clinical manifestations, diagnostic criteria, and the importance of distinguishing viral from bacterial causes. Therapeutic interventions like antibiotics and tonsillectomy indications are evaluated within evolving guidelines. Regarding sinusitis, it explores its origins, contributing factors, and classification based on duration and pathophysiology. Viral infections, allergens, and structural anomalies' roles in pathogenesis are highlighted. Diagnostic modalities like imaging and endoscopic exams are assessed for their efficacy in guiding management decisions. The importance of precise diagnosis through clinical examination, microbiological testing, and imaging is emphasized for informed treatment choices. This review also delves into minimally invasive surgical procedures, particularly endoscopic sinus surgery and tonsillectomy, showcasing progress in these areas. In summary, it provides insights into tonsillitis and sinusitis, offering perspectives on their aetiology, diagnosis, and treatment while integrating current research and clinical standards to enhance patient care and healthcare resource utilization.

Principles of Treatment and Clinical-Evolutionary Peculiarities of Deep Cervical Spaces Suppurations-Clinical Study

As medical-surgical emergencies, regardless of the causal agent, deep cervical space suppurations are not only a diagnostic challenge, but also a therapeutic one. In some cases, in spite of proper therapeutic measures, extremely severe complications can develop. A 5-year retrospective study (2016-2020) was conducted on a group of 107 patients suffering from cervical suppurations, being hospitalized and treated in the ENT Clinic of the "Sf. Apostol Andrei" Emergency County Hospital of Galați. This research is a clinical-statistical study based on the experience of this ENT clinic and was carried out based on the analysis of the patients' medical records. Descriptive analysis' statistical methods of the data series collected from the clinical observation sheets were used, with the patients' informed consent for the processing of the aforementioned data, with the agreement of the Ethics Commission of the Emergency Clinical Hospital "Sf. Apostol Andrei" Galați and the College of Physicians Galați, România. The patients' clinical and multidisciplinary treatment features included in the study group are presented. The results highlight the clinical particularities of deep cervical space suppurations treatment, including under COVID-19 impact, or with other comorbidities, having consequences on the case mix index increase or directly on the costs, admittance duration and the clinical status of the patient at discharge. The conclusions of the clinical study are based on the fulfillment of the research objectives in terms of treatment and symptomatology of deep cervical space suppurations and under the impact of comorbidities (global health crisis and pandemic, triggering of comorbidities due to health care access difficulty in the context of anti-COVID-19 government-implemented measures and the infection-rate that overburdened the medical system in the early period of the pandemic). Individualized treatment of deep cervical space suppurations is recommended to be approached multidisciplinary. Of particular importance is early diagnosis combined with prompt and correctly instituted multidisciplinary treatment. In this context, an appropriate medical measure that we recommend is patient health education, as it was observed in the clinical study: most times, patients address medical services with advanced disease, hence the generally unfavorable prognosis and outcome (about 25% of patients develop unfavorable prognosis and 4% die).

MRI Findings in Acute Tonsillar Infections

BACKGROUND AND PURPOSE

Previous literature is vague on the prevalence and exact nature of abscesses in tonsillar infections, ranging from intratonsillar and peritonsillar collections to deep extension involving the parapharyngeal and retropharyngeal spaces. MR imaging has excellent diagnostic accuracy in detecting neck infections and can potentially clarify this issue. We sought to characterize the spectrum of MR imaging findings regarding tonsillar infections.

MATERIALS AND METHODS

We conducted a retrospective cohort study of emergency neck MR imaging scans of patients with tonsillar infections. Imaging data were assessed in terms of signs of infection and the location of abscesses and were compared with clinical findings, final diagnoses, and surgical findings as reference standards.

RESULTS

The study included 132 patients with tonsillar infection. Of these, 110 patients (83%) had ≥1 abscess (99 unilateral, 11 bilateral; average volume, 3.2 mL). Most abscesses were peritonsillar, and we found no evidence of intratonsillar abscess. Imaging showed evidence of parapharyngeal and retropharyngeal extension in 36% and 10% of patients, respectively. MR imaging had a high positive predictive value for both abscesses (0.98) and deep extension (0.86). Patients with large abscesses and widespread edema patterns had a more severe course of illness.

CONCLUSIONS

Emergency neck MR imaging can accurately describe the extent and nature of abscess formation in tonsillar infections.

Pediatric Neck Masses: Imaging Guidelines and Recommendations

Neck masses commonly present in children and several potential diagnostic and management pathways exist, though with a paucity of evidence-based recommendations. The purpose of this article is to evaluate the current literature and utilization of various diagnostic imaging modalities , with a review of imaging features and management pearls for pediatric neck masses. A comprehensive understanding and practical imaging workflow will guide optimal patient workup and management.

The treatment of streptococcal tonsillitis/pharyngitis in young children

Pharyngitis is common in children, accounting for nearly 12 million visits annually in the United States. Streptococcus pyogenes or group A streptococcus (GAS) is the most common bacterial cause of pharyngitis for which antibiotics are indicated. Antibiotic treatment of streptococcal pharyngitis virtually eliminates the presence of bacteria from the pharynx and thus removes the risk of subsequent rheumatic fever. GAS is spread from person to person via respiratory droplets with a short incubation period of 2∼5 days. GAS pharyngitis peaks in the late winter and early spring months when children are predominately indoors for school and sports. Colonization is also higher in winter months, and while up to 20% of school age children are colonized with GAS in their throat during this time, colonization has not been shown to contribute to the spread of disease. In low- and middle-income countries and other situations in which crowding is common (e.g., schools), outbreaks of pharyngitis are common. GAS pharyngitis can occur at all ages and it is most common in school-aged children with a peak at 7∼8 years of age. Pharyngitis caused by GAS is rare in children <3 years of age and becomes much less common in late adolescence through adulthood.

Application of Coblation Tonsillectomy with Inferior Pole Capsule Preservation in Pediatric Patients

OBJECTIVES/HYPOTHESIS

To evaluate the application and advantages of coblation tonsillectomy with inferior pole capsule preservation in pediatric patients with tonsillar hypertrophy and recurrent tonsillitis.

STUDY DESIGN

Retrospective chart review.

METHODS

A total of 726 children who were diagnosed with either tonsillar hypertrophy or recurrent tonsillitis were included. Children were divided into two groups according to the surgical technique: conventional coblation tonsillectomy and coblation tonsillectomy with inferior pole capsule preservation. The duration of surgery, intraoperative hemorrhage volume, and postoperative pain, as well as postoperative hemorrhage data in the format of time, location, and degree were compared between the two groups.

RESULTS

Of the 726 children included, conventional coblation tonsillectomy was performed in 320 children, coblation tonsillectomy with inferior pole capsule preservation was performed in 406 children. There were no significant differences in duration of surgery or intraoperative hemorrhage volume between the two groups. Children who underwent coblation tonsillectomy with inferior pole capsule preservation showed a remarkable improvement in postoperative pain on days 3 and 5 postoperatively. Additionally, the coblation tonsillectomy with inferior pole capsule preservation group exhibited a significantly lower total postoperative hemorrhage rate, secondary hemorrhage rate, and hemorrhage rate in the inferior pole compared with that in the conventional coblation tonsillectomy group. During the 1-year follow-up period, no cases of tonsillar re-hypertrophy or recurrent tonsillitis were observed in either group.

CONCLUSION

For pediatric tonsillar hypertrophy and recurrent tonsillitis, coblation tonsillectomy with inferior pole capsule preservation is a safe and effective technique, capable of reducing postoperative pain and hemorrhage, especially secondary hemorrhage at the inferior pole.

Comparing febrile children presenting on and off antibiotics to the emergency department: a retrospective cohort study

Background

It is not yet known how antibiotics may affect Serious Bacterial Infections (SBI). Our aim is to describe the presentation, management, and serious bacterial infections (SBI) of febrile children on or off antibiotics.

Methods

Retrospective, cohort study of febrile Emergency Department patients, 0–36 months of age, at a single institution, between 2009and 2012.

Results

Seven hundred fifty-three patients were included: 584 in the No-Antibiotics group and 169 (22%) in the Antibiotics group. Age and abnormal lung sounds were predictors for being on antibiotics (OR 2.00 [95% CI 1.23–3.25] and OR 1.04 [95% CI 1.02–1.06] respectively) while female gender, and lower temperatures were negative predictors (OR 0.68 [95%0.47–0.98] and OR 0.47 [95% CI 0.32–0.67] respectively). Antibiotics were prescribed by a physician 89% of the time; the most common one being Amoxicillin/Clavulanic Acid (39%). The antibiotic group got more blood tests (57% vs 45%) and Chest X-Rays (37% vs 25%). Overall, the percent of SBIs (and pneumonias) was statistically the same in both groups (6.5% in the No-antibiotic group VS 3.6%).

Conclusions

Children presenting on antibiotics and off antibiotics were significantly different in their presentation and management, although the overall percentages of SBI were similar in each group. Further investigations into this subgroup of febrile children are needed.

Retropharyngeal Tuberculous Abscess: A Rare Cause of Upper Airway Obstruction and Obstructive Sleep Apnea in Children: A Case Report

Retropharyngeal tuberculous abscess (RPTBA) is a rare manifestation of tuberculosis (TB) even in high TB burden areas. It rarely manifests as a cause of upper airway obstruction and obstructive sleep apnea (OSA) in children with few case reports in the literature. We report a 22 months old toddler who presented with upper airway obstruction and OSA and was diagnosed with RPTBA. The child recovered completely and growing normally after intra-oral aspiration and 6 months of anti-tuberculosis treatment.

Comparison of Alere i Strep A Rapid Molecular Assay With Rapid Antigen Testing and Culture in a Pediatric Outpatient Setting

OBJECTIVES

Group A Streptococcus (GAS) is the most common bacterial cause of pediatric acute pharyngitis, and its quick identification is important for subsequent treatment. We sought to determine whether molecular GAS-based testing can successfully replace GAS antigen testing and subsequent culture in a pediatric urgent care center.

METHODS

We tested 160 patient oropharyngeal samples by a rapid antigen GAS test, the Alere i Strep A test, and throat culture in a pediatric urgent care setting and calculated basic statistical metrics.

RESULTS

The sensitivity and specificity of the molecular test were 98% and 100%, respectively, compared with culture. There was a 9% false-positive rate with the rapid antigen-based testing.

CONCLUSIONS

The Alere test is sufficiently sensitive and specific for definitive GAS testing in a pediatric urgent care setting. This implementation has enabled us to provide definitive patient results at the time of each patient encounter.

Clinical Mimics: An Emergency Medicine-Focused Review of Streptococcal Pharyngitis Mimics

BACKGROUND

Pharyngitis is a common disease in the emergency department (ED). Despite a relatively low incidence of complications, there are many dangerous conditions that can mimic this disease and are essential for the emergency physician to consider.

OBJECTIVE

This article provides a review of the evaluation and management of group A β-hemolytic Streptococcal (GABHS) pharyngitis, as well as important medical conditions that can mimic this disease.

DISCUSSION

GABHS pharyngitis often presents with fever, sore throat, tonsillar exudates, and anterior cervical lymphadenopathy. History and physical examination are insufficient for the diagnosis. The Centor criteria or McIsaac score can help risk stratify patients for subsequent testing or treatment. Antibiotics may reduce symptom duration and suppurative complications, but the effect is small. Rheumatic fever is uncommon in developed countries, and shared decision making is recommended if antibiotics are used for this indication. Oral analgesics and topical anesthetics are important for symptom management. Physicians should consider alternate diagnoses that may mimic GABHS pharyngitis, which can include epiglottitis, infectious mononucleosis, Kawasaki disease, acute retroviral syndrome, Lemierre's syndrome, Ludwig's angina, peritonsillar abscess, retropharyngeal abscess, and viral pharyngitis. A focused history and physical examination can help differentiate these conditions.

CONCLUSIONS

GABHS may present similarly to other benign and potentially deadly diseases. Diagnosis and treatment of pharyngitis should be based on clinical evaluation. Consideration of pharyngitis mimics is important in the evaluation and management of ED patients.

Correlation of MDR1 gene polymorphism with propofol combined with remifentanil anesthesia in pediatric tonsillectomy

The motive of this study was to investigate the interaction between polymorphisms in the MDR1 gene and anesthetic effects following pediatric tonsillectomy. In total, 240 children undergoing tonsillectomy with preoperative propofol-remifentanil anesthesia were selected. Genomic DNA was extracted from the peripheral blood of children after operation, and the MDR1 gene polymorphisms of 2677 G>T/A, 1236 C>T and 3435 C>T were detected by direct sequencing. We tested mean arterial pressure, diastolic blood pressure, systolic blood pressure, and heart rate at several time-points: T0 (5 mins after the repose), T1 (0 min after tracheal intubation), T2 (5 mins after the tracheal intubation), T3 (0 min after the tonsillectomy), T4 (0 min after removal of the mouth-gag) and T5 (5 min after the extubation). The visual analog scale, the face, legs, activity, cry, and consolability pain assessment, and the Ramsay sedation score were recorded after the patients regained consciousness. Adverse reactions were also recorded. The time of induction, respiration recovery, eye-opening, and extubation of children with the CC genotype were found to be shorter compared to the CT + TT genotype of MDR1 1236C > T (all P <.05). The mean arterial pressure, diastolic blood pressure, systolic blood pressure, and heart rate were significantly reduced at T5 in children with the CC genotype (all P <.05). The visual analog scale at 1, 2, 4, and 8 hours post-operation, and the Ramsay sedation score at 5, 10, and 30 min after the extubation were decreased, while the face, legs, activity, cry, and consolability pain assessment score increased (all P <0.05). There was no statistically significant difference in the adverse reaction of MDR1 mutations (P> 0.05). It could be concluded that anesthetic effect following pediatric tonsillectomy in patients with the MDR1 1236C > T CC genotype was stronger than in those carrying the CT + TT genotype.
