Pediatric Patient and Hospital Characteristics Associated With Treatment of Peritonsillar Abscess and Peritonsillar Cellulitis

Computed tomography use patterns for pediatric patients with peritonsillar abscess

OBJECTIVES

The objective of this study is to examine the impact that an institution-wide policy to reduce radiation exposure in pediatric patients had on the use of computed tomography (CT) imaging in children presenting with suspected peritonsillar abscess (PTA)1.

METHODS

A single institution retrospective review was conducted for all pediatric patients under the age of 18 who presented to the emergency department with suspected PTA over a ten-year period. Patients were divided into two groups; those that presented during the years prior to policy implementation and those that presented during the years following. Main outcome measures were the frequency of patients who underwent CT scanning as a part of their workup, the specialty of the ordering physician, and the treatment for suspected PTA.

RESULTS

A total of 317 patients with suspected PTA were seen prior to policy implementation, with an additional 275 patients seen in the years after. The frequency of CT use was 41% (131/317) in pre-policy patients, and 28% (77/275) in post-policy patients (p = 0.004). The most common specialty of ordering physician was Pediatrics in the pre-policy patients (45%), and Otolaryngology in the post-policy patients (41%) (p = 0.0003). Of the 131 patient who underwent CT scanning before policy implementation, 36 patients (27%) required incision and drainage (I&D) of their PTA in the OR. This is in comparison to 42/77 patients (55%) in the post-policy group who underwent I&D in the OR (p < 0.0001).

CONCLUSION

An institution-wide policy to decrease unnecessary imaging studies in pediatric patients resulted in a significant reduction in the use of CT imaging in the work-up for suspected PTA. Additionally, there was increase in the frequency of patients who underwent surgical intervention for their PTA after CT imaging, suggesting a more scrutinized approach to CT usage since policy implementation.

Utilization of emergency department computed tomography and otolaryngology consultation in the diagnosis of pediatric peritonsillar abscess

OBJECTIVES

To determine whether obtaining a computed tomography (CT) scan in the emergency department (ED) is predictive of peritonsillar abscess (PTA) in the pediatric population, and to evaluate for clinical characteristics that may suggest whether a CT is beneficial in the diagnosis of pediatric PTA.

METHODS

Single-institution retrospective chart review at Rush University Hospitals. Study included pediatric patients, aged 17 or younger, who presented to the ED with suspected PTA over a 6-year period. Patients received a neck CT and/or an official otolaryngology consultation. Relevant demographic and study parameters were collected and statistically analyzed using SPSS.

RESULTS

A total of 36 pediatric patients with suspected PTA. Of these, 47.2% (17/36) received a diagnosis of PTA while 52.8% (19/36) received an alternative diagnosis. Patients with PTA were more likely to have trismus (41.2% vs 5.3%; p < .01), uvular deviation (94.1% vs 15.8%; p < .01), and palatal edema (52.9% vs 10.5%; p < .01), compared to patients without PTA. Fewer CT scans were ordered when comparing PTA positive versus negative cohorts (35% vs 63.2%; p = .10), however this was not statistically significant. An otolaryngology consult prior to imaging did significantly reduce the frequency of ordered CT scans (12.5% vs 63.6%; p < .01).

CONCLUSION

This is the first study to investigate the benefit of CT imaging in the diagnosis of pediatric PTA and impact of an otolaryngology consult on the frequency of CT scans. Pediatric patients at high risk for PTA based on clinical findings may not require CT imaging for diagnosis. Patients at lower risk may benefit from imaging based on the availability of an otolaryngology consult or expertise of the examiner.

Predictors of intratonsillar abscess versus peritonsillar abscess in the pediatric patient

OBJECTIVE

To determine the incidence of intratonsillar abscess (ITA) patients within the population of patients diagnosed with peritonsillar abscess (PTA) and to further characterize the differences in symptomatology and successful treatment strategies between the two groups.

METHODS

This study is a retrospective chart review of patients diagnosed with PTA or ITA at our institution from 2000 to 2017. Descriptive and inferential statistics are reported, including univariate and multivariate analyses.

RESULTS

A total of 335 pediatric (<18 years) patients presenting with a PTA or ITA were identified, 31 (9%) of whom were diagnosed with ITA. Patients with ITAs had significantly lower proportions of trismus, otalgia, and dysphagia and were less likely to experience acute progression from their initial symptoms. The ITA group had fewer attempted aspiration and drainage attempts, with those attempts significantly less successful than for the PTA group. Recurrence was uncommon in ITA patients in comparison to PTA patients.

CONCLUSIONS

Intratonsillar abscess should be considered in the differential diagnosis for patients presenting with sore throat and concern for a pharyngeal infection or abscess. These patients have a significantly lower proportion of otalgia, trismus, vocal changes, and dysphagia. Given the low success rate of drainage attempts and lower recurrence rate, diagnosing physicians should consider medical management rather than procedural drainage in this patient population.

Cellulitis of the Knee in a 16-Month-Old Boy: A Case Report

OBJECTIVE

The purpose of this case report is to describe the presentation of cellulitis in a 16-month-old boy to a chiropractic clinic.

CLINICAL FEATURES

The patient presented with nontraumatic, sudden onset of nonpurulent erythema on the right knee. A plain film radiograph of the knee showed a 40-mm thickening of the anterior knee. A diagnosis of cellulitis was rendered based on the presentation of the rapidly spreading erythema and radiographically confirmed findings.

INTERVENTION AND OUTCOME

The patient was immediately referred to the local emergency room. The patient was hospitalized, treated with clindamycin and amoxicillin for 3 days, and then discharged. The patient's pediatrician discontinued clindamycin treatment at the posthospitalization follow-up. Two weeks after treatment was discontinued, the patient was diagnosed with recurrent cellulitis.

CONCLUSION

This case demonstrated that for this young patient with cellulitis of the knee, timely recognition and referral, together with patient or parent education and immediate treatment, were essential to a successful outcome.
