Article Synopsis
- A study from the Royal Hospital for Children in Glasgow examined long-term airway issues in kids with oesophageal atresia and tracheoesophageal fistula (OA/TOF) and found that 83% experienced airway symptoms.* -
- Out of 121 patients, many underwent airway endoscopy, revealing issues like airway malacia and subglottic stenosis, with significant surgical interventions needed for 40% of them.* -
- The findings suggest that long-term airway problems are common and often treatable, highlighting the need for clinicians to appropriately refer these patients to airway specialists.*
Article Synopsis
- Research on flowering plants has evolved from focusing solely on pollinator specificity to considering introgressive hybridization as a significant factor affecting species relationships.
- A study on fig trees (Moraceae) uses extensive genetic sampling to explore phylogenetic ties and the role of hybridization among 520 species, revealing that local introgression occurs despite overall reproductive isolation.
- Findings indicate that while hybridization contributes to plant evolution, strong plant-pollinator relationships can prevent ongoing hybridization between unrelated lineages, maintaining genetic stability in figs.
Congenital nasal pyriform aperture stenosis; our experience of 34 cases.
Int J Pediatr Otorhinolaryngol
March 2023
Objectives: To study our population of patients with congenital nasal pyriform aperture stenosis (CNPAS) in terms of incidence and socioeconomic status; the effect of pyriform aperture size, gestational age, birth weight, and whether congenital abnormalities are associated with surgical requirement.
Methodology: Retrospective case note review of all patients treated for CNPAS at a single tertiary paediatric referral site was undertaken. Diagnosis was made on the basis of a pyriform aperture of <11 mm on CT scanning; patient demographics were collected to explore risk factors for surgery and surgical outcomes.
Premise: The ~140 species of Lonicera are characterized by variously fused leaves, bracteoles, and ovaries, making it a model system for studying the evolution and development of organ fusion. However, previous phylogenetic analyses, based mainly on chloroplast DNA markers, have yielded uncertain and conflicting results. A well-supported phylogeny of Lonicera will allow us to trace the evolutionary history of organ fusion.

Int J Pediatr Otorhinolaryngol
January 2023
Background: Up to half of all children who have a tracheostomy will develop a persistent tracheo-cutaneous fistula (TCF) after decannulation. Surgical closure of the TCF is technically easy but post-operative complications can be immediate and life-threatening. These include air leak from the tracheal repair leading to massive surgical emphysema or pneumothorax.
