RESUMO
The aim of this study was to determine whether high-intensity focused ultrasound (HIFU) therapy under nasal endoscopy guidance could provide better efficacy and safety in patients with persistent allergic rhinitis (PAR) than the first-line drugs recommended by the World Health Organization. A total of 120 adult patients with PAR were randomly divided into 2 groups (N = 60 each). One group underwent HIFU therapy under nasal endoscopy guidance using an ultrasound rhinitis therapeutic machine. The other group served as the control group and was treated with corticosteroid nasal spray and oral cetirizine hydrochloride. All patients underwent follow-up treatment for 1 year, after which the efficacy and safety were evaluated. There was no significant difference between the two groups (P > 0.05) in the total effective rate. Moreover, no complications such as nasal adhesion, septal perforation, mucosal atrophy, and hyposmia were observed, indicating that HIFU was as effective as the first-line drug treatments recommended by the World Health Organization for symptom relief in PAR patients. The treatment efficacy, repeatability, safety, economical aspects, ease of performance, and few complications of HIFU therapy strongly suggest that HIFU should be routinely incorporated into clinical practice.

The purpose of this study was to investigate the changes in the humoral and cellular immunity of children with obstructive sleep apnea-hypopnea syndrome and hypertrophy of tonsils before and after plasma-mediated temperature-controlled radiofrequency ablation treatment. Fifty-seven children suffering from obstructive sleep apnea-hypopnea syndrome and with hypertrophy of tonsils were enrolled in this study. Thirty-seven children were grouped in the partial tonsillectomy group and 20, in the tonsillectomy group. The levels of CD3(+), CD4(+), CD8(+), and CD4(+)/CD8(+) were measured for cellular immunity, and the levels of IgG, IgA, and IgM were measured for humoral immunity. Blood samples were collected before and 1 and 3 months after the operation. The IgG, IgA, and IgM levels in the tonsillectomy group were significantly decreased 1 month after the operation, and recovered to the normal levels within 3 months of the operation (P < 0.05). However, the levels of IgG, IgA, and IgM in the partial tonsillectomy group decreased slightly, without a significant difference (P > 0.05). The cellular immunity of the 2 groups was not statistically different pre- and post-operation (P > 0.05). The results from the present study indicate that partial tonsillectomy by plasma-mediated temperature-controlled radiofrequency ablation did not impact on the humoral and cellular immunity of children.
