Background: Adenoidal hypertrophy (AH) is commonly observed in childhood and closely linked to obstructive sleep apnea (OSA). Despite the high prevalence of AH, its pathophysiological mechanisms remain incompletely understood. We attempt to explore this issue from a genetic perspective. Elevated levels of LINC00461 have been identified in OSA tissues. We aimed to explore the relationship between susceptibility to adenoid hypertrophy and LINC00461 gene polymorphisms.
Methods: We genotyped the LINC00461 single nucleotide polymorphisms (SNPs) rs933647 and rs201864123 in 546 AH patients and 574 healthy controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between the SNPs and AH risk. The SIPI (Susceptible-Infected-Protected-Infected) method was utilized to analyze SNP-SNP interactions between rs933647 and rs201864123.
Results: Our study found that the rs933647 GA polymorphism was associated with an increased risk of AH. Similarly, the T allele of SNP rs201864123 increased AH risk in southern Chinese children. Furthermore, SIPI analysis demonstrated an interaction between these SNPs associated with adenoid hypertrophy risk.
Conclusion: The LINC00461 rs933647 GA genotype and rs201864123 T variant may contribute to the susceptibility of AH in the child population of China.

Adenoid hypertrophy is one of the most common upper respiratory tract disorders during childhood, leading to a range of symptoms such as nasal congestion, mouth breathing and obstructive sleep apnea. Current diagnostic methods, including computerized tomography scans and nasal endoscopy, are invasive or involve ionizing radiation, rendering them unsuitable for long-term assessments. To address these clinical challenges, this paper proposes a novel deep learning approach for the non-invasive detection of adenoid hypertrophy using heartlung sounds.

Objective: To observe the clinical efficacy of deep needling at Xiaguan (ST7) combined with electroacupuncture and warm acupuncture for adenoid hypertrophy (AH) in children.
Methods: Seventy-two children with AH were randomly divided into an observation group (36 cases, 5 cases dropped out, 1 case was eliminated) and a control group (36 cases, 4 cases dropped out, 2 cases were eliminated). The observation group received deep needling at Xiaguan (ST7) combined with electroacupuncture and warm acupuncture.

Adenoid hypertrophy, characterized by the abnormal enlargement of adenoid tissue, is a condition that can cause significant breathing and sleep disturbances, particularly in children. Accurate diagnosis of adenoid hypertrophy is critical, yet traditional methods, such as imaging and manual interpretation, are prone to errors. This study uses an ensemble deep learning-based approach for adenoid classification.

Background: Adenoid hypertrophy is a common disorder of childhood, and has an unclear pathogenesis. At the beginning of the COVID-19 pandemic, there was a significant reduction in the incidence of adenoid hypertrophy in children under long-term home quarantine, providing a rare research model to explore the pathogenesis and treatment targets of adenoidal hypertrophy in children.
Methodology: Before and during the home quarantine period, adenoids that underwent surgery were detected using label-free proteomics.
