The performance of external ventricular drainage in the non-ETV group did not prevent secondary HCP (p = 0.68). Postoperative cerebellar swelling (p = 0.01), haematoma (p = 0.04), cerebrospinal fluid leak (p = 0.04) and neuroinfection (p = 0.04) were the main risk factors of persistent HCP. Performance of ETV before tumour removal is not only beneficial for control of acute HCP but also prevents the occurrence of secondary postoperative HCP and may also minimize early postoperative complications.The O(3P)-initiated conversion mechanism and dynamics of CH3CHCO were researched in atmosphere by executing density functional theory (DFT) computations. Optimizations of all the species and single-point energy computations were implemented at the B3LYP/6-311++G(d,p) and CCSD(T)/cc-pVTZ level, respectively. The explicit oxidation mechanism was introduced and discussed. The results state clearly that the O(3P) association was more energetically beneficial than the abstraction of H. The rate coefficients over the probable temperature range of 200-3000 K were forecasted by implementing Rice-Ramsperger-Kassel-Marcus (RRKM) theory. Specifically, the total rate coefficient of O(3P) association reactions is 1.19 × 10-11 cm3 molecule-1 s-1 at 298 K, which is consistent with the experimental results (1.16 × 10-11 cm3 molecule-1 s-1). The rate coefficients for the O(3P) with CH2CO, CH3CHCO, and (CH3)2CCO suggest that rate coefficient of ketene derivatives increase with the increase of methylation degree. Graphical abstract.
In chronic otitis media (COM), disease chronicity and severity of middle ear inflammation may influence the development of inner ear deficits, increasing the risk of vestibular impairment. This secondary analysis of the multinational collaborative Chronic Otitis Media Questionnaire-12 (COMQ-12) dataset sought to determine the prevalence of vestibular symptoms in patients with COM and identify associated disease-related characteristics.
Adult patients with a diagnosis of COM in outpatient settings at nine otology referral centers across eight countries were included. We investigated the presence of vestibular symptoms (dizziness and/or disequilibrium) using participant responses to item 6 of a native version of the COMQ-12. Audiometric data and otoscopic assessment were also recorded.
This analysis included 477 participants suffering from COM, with 56.2% (n = 268) reporting at least mild inconvenience related to dizziness or disequilibrium. There was a significant association between air conduction threst on their health state.
This study aims to investigate the detection rates, common symptoms and risk factors of gastroesophageal reflux disease (GERD), and laryngopharyngeal reflux disease (LPRD) at the digestive endoscopy center.
A multicenter cross-sectional survey conducted at three hospitals and a total of 565 eligible participants were enrolled. All the patients completed routine ENT examination, gastroscopy, gastroesophageal reflux questionnaire (GerdQ), reflux symptom index (RSI) and a self-designed 25-item symptoms table survey.
Among the 565 eligible participants, the detection rates of GERD and LPRD were 18.41% (104/565) and 9.91% (56/565), respectively. The detection rate of GERD combined with LPRD was 3.19% (18/565). Among GERD and LPRD patients, males (vs. females), middle-aged and elderly patients (vs. young people), BMI ≥ 24.0kg/m
(vs. BMI < 24.0kg/m
), with current smoking history (vs. no smoking), and current drinking history (vs. no drinking), lying down immediately after meal (vs. selleck inhibitor no lying down immediately after meal) were significantly higher (all p < 0.05). The most common extraesophageal symptoms in patients with GERD were dry mouth (66.35%), globus sensation (56.73%), dry throat and pharyngeal itching (55.77%). The most common extraesophageal symptoms in patients with LPRD were globus sensation (91.07%), dry throat and pharyngeal itching (83.93%), and dry mouth (82.14%).
GERD and LPRD had a high detection rate at the digestive endoscopy center in Guangzhou, China. Older age, BMI ≥ 24.0kg/m
, smoking and drinking history were risk factors for both GERD and LPRD. Neither GerdQ nor RSI scores included common extraesophageal symptoms.

To investigate the long-term safety and efficacy of a 3D-printed bioresorbable polycaprolactone (PCL) nasal implant for nasal septal deformity reconstruction.
Fourteen patients who had undergone nasal septum reconstruction surgery using 3D-printed PCL nasal septal implants were enrolled. The primary outcome was the change in total Nasal Obstruction Symptom Evaluation (NOSE) scale scores between postoperative 3months and current status (3.59 ± 0.51years). The secondary outcomes were changes in the minimum cross-sectional area (MCA) and volume of both nasal cavities based on acoustic rhinometry, the cross-sectional area of the ostiomeatal unit, and the nasal septum angle of the paranasal sinus (PNS) in computed tomography (CT) images, and a visual analog scale (VAS) of the patients' subjective satisfaction.
The results showed no significant changes in the MCAs (Cohen's d0.09; p = 0.711) or nasal volume (Cohen's d0.26; p = 0.356), the area of the ostiomeatal unit (Cohen's d0.49; p = 0.064), septum angles (Cohen's d0.18; p = 0.831), the NOSE scale (Cohen's d0.14; p = 0.621), or patients' subjective satisfaction (Cohen's d0.52; p = 0.076) during the follow-up period.
This homogeneous composite microporous PCL nasal septal implant demonstrated long-term clinical efficacy and safety in human tissues that required maintenance of mechanical strength. Therefore, the indications for this implant could extend to various other craniofacial reconstructions in the future.
