Pediatric oral maxillofacial management and artificial intelligence / 临床耳鼻咽喉头颈外科杂志

With the enhancement of aesthetic awareness of children's oral maxillofacial development, multi-disciplinary doctors pay attention to children's oral maxillofacial management. Artificial intelligence (AI) technology has been gradually applied to all fields of children's oral maxillofacial management because of its outstanding advantages in medical screening and auxiliary decision-making. This article reviews the application of AI technology in the screening, diagnosis, treatment and follow-up of oral maxillofacial management in children.

Application of virtual endoscopy in the diagnosis of adenoid hypertrophy and the morphologic classification of adenoid / 临床耳鼻咽喉头颈外科杂志

Objective:To discuss the application of virtual endoscopy in the diagnosis of adenoid hypertrophy and the morphologic classification of adenoid. Methods:The clinical data of 97 children with adenoid hypertrophy admitted to Department of Otorhinolaryngology Head and Neck Surgery, Shenzhen University General Hospital from July 2022 to December 2022 were collected. The virtual endoscopic reconstruction of the nasopharynx was performed by cone beam computed tomography. The results of virtual endoscopic adenoid size measurement were compared with the results of nasopharyngeal CT median sagittal position and nasopharyngeal endoscopy. Virtual endoscopic classification of adenoid based on the size of the adenoids and their relationship with the torus tubarius. Results:The t-test results of the size of adenoids measured by virtual endoscopy and nasopharyngeal CT were t=1.699 and P=0.093, and the results of intra-group correlation coefficient（ICC） analysis were ICC=0.921 and P<0.01. The proportion of adenoids measured by virtual endoscopy and nasopharyngeal CT was highly consistent. The t-test results of the size of adenoids measured virtual endoscopy and nasopharyngeal endoscopy were t=1.543 and P=0.15, and the results of intra-group correlation coefficient（ICC） analysis were ICC=0.900 and P<0.01. The proportion of adenoids measured by virtual endoscopy and nasopharyngeal endoscopy was highly consistent. Among the 97 children, the morphological classification results of adenoids were 48 cases of overall hypertrophy type, 47 cases of central bulge type, and 2 cases of flat thickening type. Conclusion:The diagnosis of adenoid hypertrophy by virtual endoscopy has high accuracy, which not only avoids the invasive operation of traditional nasopharyngeal endoscopy, but also can observe the adenoid condition and its relationship with the torus tubarius from multiple angles. And, the morphological classification of adenoids using virtual endoscopy has guiding significance for perioperative preparation.

Study on the Preparation and Quality Control of Papaverine-nitroglycerin Ointment / 中国药房

OBJECTIVE:To prepare papaverine-nitroglycerin ointment and to establish a method for its quality control.METHODS:Nitroglycerin,papaverine hydrochloride and diclofenac potassium were used as basic remedies to prepare oint?ment.The contents of nitroglycerin,papaverine hydrochloride and diclofenac potassium were determined by UV-spec?trophotometric methods.RESULTS:The average recovery rates of Nitroglycerin,papaverine hydrochloride and diclofenac potassium were100.65%、99.86%、100.55%respectively,and RSD equal to0.4945%、0.1719%、0.3205%respectively(n=3). CONCLUSION:The ointment preparation is feasible in technique,reliable in quality control and stable in quality.
