ABSTRACT Objective: To investigate the prevalence and associated risk factors of metabolic syndrome (MS) in patients with obstructive sleep apnea (OSA). Methods: From July 2007 to June 2017, a total of 8 155 adult subjects, including 6 484 males and 1 671 females, aged 18-90 (43.13±12.28), body mass index 14.61~59.56 (25.59±3.98) kg/m2,who were admitted to the Department of Otorhinolaryngology head and Neck surgery of The Sixth People's Hospital affiliated to Shanghai Jiao Tong University, were retrospectively analyzed. All patients underwent polysomnography and biochemical tests. Subjects were divided into four groups (non-OSA, mild OSA, moderate OSA, and severe OSA) according to OSA severity. The prevalence of MS was expressed as percentage, and the correlation between OSA and MS and its c haracteristic pathophysiological indicators was evaluated by logistic regression model after adjusting for factors such as gender, age, BMI, neck circumference, hip circumference, smoking and alcohol consumption, and was expressed by odds ratio (OR). SPSS 25.0 software was used for statistical analysis. Results: The overall prevalence of MS was 43.6%, and that of non-/mild/moderate/severe OSA group was 18.6%, 30.4%, 43.8%, 57.1%.Logistic regression showed that patients with mild/moderate/severe OSA had an increased risk of MS compared with non-OSA patients, with adjusted OR values and confidence intervals of 1.27 (1.05-1.54), 1.84 (1.53-2.22), and 2.08 (1.76-2.46), respectively (P<0.01).In addition, indicators of OSA anoxic burden [oxygen drop index(Toxygen=7.1), minimum blood oxygen(Tminimum=56.3), blood oxygen saturation below 90% cumulative time ratio (TCT90=10.6) ]were closely associated with MS disease(P<0.01), but sle ep fragmentation index (arousals index) was not significantly associated with MS disease. Conclusion: The risk of MS gradually increases with the severity of OSA, and the indicators reflecting OSA hypoxia burden are closely related to MS disease.

ABSTRACT Currently, the number of patients with bilateral sensorineural deafness treated with cochlear implantation (CI) is increasing in the Russian Federation. In this regard, methods of assessing the auditory rehabilitation of this category of patients become more relevant. OBJECTIVE: To investigate the correlation of the speech intelligibility in quiet with frequency resolving power (FRP) of hearing using a ripple-spectrum phase reversion test (RSPRT) in CI users. MATERIAL AND METHODS: The study includes 30 CI users, three of them after bilateral CI, aged from 13 to 63 years with CI usage experience from 1 year to 16 years. 19 patients used CI systems manufactured by Cochlear Ltd. (Australia), 11 patients used CI systems manufactured by Advanced Bionics (Switzerland). All subjects underwent a number of studies including pure tone audiometry (TPA) , speech audiometry in quiet using a multi-syllable speech material on a two-channel clinical audiometer AC-40 (Interacoustics A/S, Denmark); PC with recorded phonetic material from which the signal was reproduced, acoustic speaker SP90 (Interacoustics A/S, Denmark), for FRP estimation - RSPRT test in a free sound field, which was installed on the PC and also reproduced through SP 90 speakers (Interacoustics A/S, Denmark) were used. RESULTS: According to TPA results in a free sound field, the sound perception thresholds in all subjects corresponded to the mild degree sensorineural hearing loss. The sound perception threshold in the free sound field in the range from 500 Hz to 4 kHz was within the range of 25-30 dB nHL. The percentage of speech intelligibility in quiet in the free sound field ranged from 5 to 100%. During the FRP study of patients using RSPRT test, the following results were obtained: the average value of RSPRT test results at the frequency of 1 kHz was 1.94 RP O; for 2 kHz - 2.3 RPO; for 4 kHz - 2.2. The significant correlation between the speech intelligibility in quiet and frequency resolution of hearing was obtained at 1 and 4 kHz. The highest correlation coefficient was detected at 1 kHz - r=0.57 (p=0.0005), while at 4 kHz it was lower - r=0.46 (p=0.009), and at 2 kHz - at the boundary of the significance: r=0.34 (p=0.051). CONCLUSIONS: As a result of the study, it was found that there is a correlation between speech intelligibility in quiet and FRP of hearing, which makes it possible to recommend the use of RSPRT in assessing the auditory rehabilitation of patients after CI.

Laryngeal cysts in children

xlomafota13 shared this article with you from Inoreader Laryngeal cysts in children Via Vestnik otorinolaringologii Vestn Otorinolaringol. 2021;86(6):57-61. doi: 10.17116/otorino20218606157. ABSTRACT Laryngeal cysts in children are relatively rare, occupying the 4-5th place in the structure of congenital malformations. The paper presents the combined experience of two Russian pediatric otorhinolaryngological clinics traditionally involved in the rehabilitation of patients with congenital and acquired pathology of the larynx. OBJECTIVE: To analyze the features of the clinic, diagnosis and treatment of laryngeal cysts in children. MATERIAL AND METHODS: The study included 68 children with laryngeal cysts aged from 3 days to 16 years (on average 39.5±37.0 months, Me=15.5 months). The cyst was localized in the vestibular region of the larynx in 15 (22.1%) patients, in the vocal region - in 15 (22.1%) patients, and in the sub-vocal region - in 38 (55.9%) patients. Data on the presence of a history of tracheal intubation were available in 35 ( 89.7%) children, including 35 (92.1%) of 38 children with a subfold cyst. 11 patients were admitted with a previously applied tracheostomy. RESULTS: The main reasons for going to the clinic were signs of laryngeal stenosis (stridor, signs of obstruction of the upper airways) in 60.3% of patients, dysphonia - in 33.8%, and in 5.9%, the detection of a cyst became an accidental finding. To eliminate the cyst, the method of laser marsupialization was used in 10 patients, coagulatory ablation - in 2 patients, in the remaining 56 patients, decortication was performed with microinstruments, followed by laser treatment of the cyst bed. In the follow-up, children were traced from 6 months to 7 years. We did not observe a recurrence of a cyst in any case. CONCLUSION: Currently, the lining department is the "favorite" localization of the cyst in childhood. Subclavian cysts are more common in preterm infants who need tracheal intubation. A necessary condition for radical elimination is the resection of the cyst walls. PMID:34964331 | DOI:10.17116/otorino20218606157 View on the web Inoreader. Take back control of your news feed.
