Needle aspiration of lateral neck abscess in children: A simple and effective treatment.

BACKGROUND: Cervical abscesses frequently occurred in pediatric patients. Surgical drainage is currently recommended in the cases not responding to medical therapy. Needle aspiration may represent a simple, effective and minimally invasive treatment for acute neck suppuration in selected cases. OBJECTIVE: To evaluate the effectiveness of needle aspiration in the treatment of cervical abscesses in pediatric age as an alternative to surgical drainage. METHODS: From November 2013 to November 2019, at the ENT Department of the "Bambino Gesù" Pediatric Hospital, Rome, we treated 47 children with cervical abscess by performing aspiration with a 19 G needle in wakefulness after applying local anesthetic. Parenteral antibiotic treatment was associated with all patients both before and after treatment. RESULTS: Complete regression of the abscess occurred in 46 children with no evidence of recurrence in the follow-up period. Surgical drainage was required in only one patient due to the lack of resolution of the abscess episode. No complications such as hematomas or hypertrophic scars were found in any patient. CONCLUSIONS: Our results confirm the effectiveness of needle aspiration in the treatment of cervical abscesses in children as an alternative to surgical drainage.

Prediction Model for the Differential Diagnosis of Kawasaki Disease and Acute Cervical Lymphadenitis in Patients Initially Presenting with Fever and Cervical Lymphadenitis.

OBJECTIVES: To distinguish early-stage lymph node first presentation of Kawasaki disease from acute cervical lymphadenitis, we developed an algorithm using sequential laboratory marker levels and radiologic findings. STUDY DESIGN: Data were obtained from pediatric inpatients initially presenting with fever and cervical lymphadenopathy. Discriminative factors for the differential diagnosis of acute cervical lymphadenitis and lymph node first presentation of Kawasaki disease were identified from intergroup comparison or univariate logistic regression analysis. A model for differentiating between lymph node first presentation of Kawasaki disease and acute cervical lymphadenitis was constructed using decision-tree analysis. RESULTS: Patients were divided into 2 cohorts: training (206 patients) and validation (103 patients) cohorts. A decision-tree model developed from the data of the training cohort included 3 determinants: neck computed tomography- or ultrasonography-defined abscess, percentage change in C-reactive protein level, and percentage change in neutrophil count. The prediction power of our decision-tree model for the validation cohort was superior to that of previously known laboratory markers (sensitivity of 89.5%, specificity of 88.9%, positive predictive value of 95.8%, negative predictive value of 75.0%, overall accuracy of 89.3%, and a Youden index of 0.784). CONCLUSIONS: A decision-tree model could differentiate lymph node first presentation of Kawasaki disease from acute cervical lymphadenitis with an increased accuracy. External validation based on multicenter data is needed before clinical application.

Acute cervical lymphadenitis and infections of the retropharyngeal and parapharyngeal spaces in children.

BACKGROUND: Acute cervical adenitis can evolve into suppurative cervical lymphadenitis and may sometimes be associated with infection of the retropharyngeal and parapharyngeal spaces (i.e., retropharyngeal and poststyloid parapharyngeal abscesses). This study aimed to describe the clinical presentation of acute cervical lymphadenitis and infections of the retropharyngeal and parapharyngeal spaces in children and examine the management of these conditions. METHODS: This was a retrospective study including children from 3 months to 18 years old who were hospitalized in the Pediatric Department of the Centre-Intercommunal-de-Créteil between January 2003 and May 2010. Selected cases were based on the diagnosis of acute cervical lymphadenitis, suppurative cervical lymphadenitis, or infections of the retropharyngeal or parapharyngeal spaces. Case history, clinical signs, laboratory tests, imaging, treatment and clinical course were collected from patient charts. RESULTS: We included 75 children (54 males [72%]); 62 (83%) were < 6 years old. Diagnoses were acute cervical lymphadenitis in 43 patients (57%), suppurative cervical lymphadenitis in 13 (17%), retropharyngeal or poststyloid parapharyngeal abscess in 18 (24%) and cervical necrotizing fasciitis in 1 (1%). In total, 72 patients (96%) presented fever and 34 (45%) had torticollis. Suppurative cervical lymphadenitis or abscesses of the retropharyngeal or poststyloid parapharyngeal spaces was significantly higher for children with than without torticollis (52.9% vs. 4.8%, p < 0.001). In all, 21 patients among the 44 > 3 years old (48%) underwent a rapid antigen detection test (RADT) for group A beta-hemolytic Streptococcus pyogenes; results for 10 were positive (48%). Contrast-enhanced CT scan of the neck in children with torticollis (n = 31) demonstrated an abscess in 21 (68%). Fine-needle aspiration was performed in 8 patients (11%) and 8 (11%) required surgical drainage. Bacteriology was positive in 8 patients (11%), with a predominance of Staphylococcus aureus and S. pyogenes. All patients received intravenous antibiotics and the outcome was favorable regardless of surgery. Recurrence was observed in only 1 case among the 34 patients with a follow-up visit after discharge. CONCLUSION: Our data suggest that presentation with cervical lymphadenitis associated with fever and torticollis requires evaluation by contrast-enhanced CT scan. Furthermore, abscess drainage should be restricted to the most severely affected patients who do not respond to antibiotic therapy.
