AI Article Synopsis

  • The study aimed to analyze the characteristics of aneurysmal bone cysts (ABCs) in pediatric patients at a specialized hospital.
  • A review was conducted on cases treated from 1994 to 2006, involving nine patients, mostly children around 9 years old, with various locations affected such as sinuses, mandible, and others.
  • Results showed different symptoms and outcomes, with surgical excision being the primary treatment and most effective solution, although some cases may indicate underlying bone issues that complicate treatment.

Article Abstract

Objectives: To characterize aneurysmal bone cysts (ABCs) of the head and neck as seen at a tertiary care center.

Design: A case series.

Methods: A retrospective chart review of pediatric patients with aneurysmal bone cyst of the head and neck treated at the Hospital for Sick Children during the years 1994-2006 was carried out.

Results: Nine patients with ABC were treated. The average age at diagnosis was 9.3 years (range: 5 months-15 years), six males and three females. Four cysts originated in the paranasal sinuses, two in the mandible, one in the zygoma, one in the mastoid and one in the parietal bone. Two cases were associated with a previous localized trauma (mandible, zygoma). 5/9 presented with pain, 4/9 presented as an asymptomatic mass, 2/9 were associated with proptosis and nasal obstruction, 2/9 with nasal obstruction and 1/9 presented with an aural polyp. Seven cysts were successfully excised while one (in the pterygomaxillary fossa) is being followed conservatively. In one case the ABC was found to be secondary to an extensive osteoblastoma and this child continuous to be problematic. Follow-up time ranged from 2 years and 6 months to 10 years.

Conclusions: ABC of the head and neck may vary in presentation and severity. Surgical removal is the treatment of choice at our institution and may provide a satisfying outcome. ABC may be secondary to an underlying bone pathology (e.g., osteoblastoma) which may make it refractory to treatment.

Background: BERIL-1 was a randomized phase 2 study that studied paclitaxel with either buparlisib, a pan-class I PIK3 inhibitor, or placebo in patients with recurrent or metastatic (R/M) head and neck squamous cell cancer (HNSCC). Considering the therapeutic paradigm shift with immune checkpoint inhibitors (ICIs) now approved in the first-line setting, we present an updated immunogenomic analysis of patients enrolled in BERIL-1, including patients with immune-infiltrated tumors.

Objective: The objective of this study was to identify biomarkers predictive of treatment efficacy in the context of the post-ICI therapeutic landscape.

Supraglottoplasty outcomes and peri-operative care in congenital laryngomalacia.

Eur Arch Otorhinolaryngol

January 2025

Department of Otolaryngology, Robert Debre Hospital, Assistance Publique Hôpitaux de Paris (APHP) and Paris University, 48, Boulevard Sérurier, 75019, Paris, France.

Objectives: This study aimed to identify factors predicting postoperative ICU admission, the need for orotracheal intubation (OTI), and the occurrence of supraglottic stenosis in children undergoing supraglottoplasty for laryngomalacia.

Methods: A retrospective analysis was conducted on 31 children (Dear Reviewer, we would have greatly preferred to include a larger sample size. However, as you know, this type of management is rare, and we deliberately selected a 7-year period to ensure a minimum of 30 children while avoiding significant differences in management guidelines over time.

Machine learning prediction model for oral mucositis risk in head and neck radiotherapy: a preliminary study.

Support Care Cancer

January 2025

Oral Diagnosis Department, Faculdade de Odontolodia de Piracicaba, Universidade de Campinas (UNICAMP), Piracicaba, São Paulo, Brazil.

Purpose: Oral mucositis (OM) reflects a complex interplay of several risk factors. Machine learning (ML) is a promising frontier in science, capable of processing dense information. This study aims to assess the performance of ML in predicting OM risk in patients undergoing head and neck radiotherapy.

Introduction: Computed tomography (CT) angiography is commonly utilized to quickly identify vascular injuries caused by blunt cervical trauma. It is often conducted alongside a cervical spine CT, based on established criteria. This study assessed the prevalence of cervical vascular injuries identified via CT angiography (CTA) in patients who had negative findings on cervical CT scans.

Background: Otitis media with effusion (OME) is associated with comorbidities such as allergic rhinitis, gastroesophageal reflux disease, asthma, and more. Many of these comorbidities can be caused by type 2 inflammation (T2I). This study aims to determine the risk of undergoing OME surgery in patients with and without T2I disease.
