Usefulness of vertebrobasilar artery radiological finding as a predictive and prognostic factor for sudden sensorineural hearing loss

Treatment of sudden sensorineural hearing loss with tinnitus with Fu subcutaneous needling: A case report

RATIONALE

Fu's subcutaneous needling (FSN) is a special acupuncture method that uses FSN to sweep the subcutaneous tissue around or adjacent to the limbs to disperse the pain. Sudden sensorineural hearing loss (SSHL) is a kind of otological emergency with sudden onset within 72 hours, with unilateral hearing loss, and hearing loss of ≥20 dB in 2 connected frequencies, and most of the patients have no obvious triggers. Most patients with SSHL are accompanied by tinnitus, vertigo, and nausea and vomiting.

PATIENT CONCERNS

The patient suffered from hearing loss with tinnitus. Although received relevant treatment, the hearing loss and tinnitus did not improve significantly.

DIAGNOSES

SSHL with tinnitus.

INTERVENTIONS

FSN treatment. A point 5 cm lateral to the point of tension and stiffness of the left trapezius muscle was selected on the affected back as the needle insertion point, and the condition of the neck muscles was improved through the FSN sweeping movement with neck reperfusion activities. The patient received treatment twice a week, and 4 weeks of treatment as a phase. At the end of each phase, a pure tone threshold audiometry, tinnitus evaluation scale Tinnitus Handicap Inventory assessment, and neck muscle palpation were performed.

OUTCOMES

The patient's hearing improved and the Tinnitus Handicap Inventory score decreased.

LESSONS

FSN has a good therapeutic effect on SSHL with tinnitus.

Circulatory disturbance of the cochlear spiral modiolar artery in a type 2 diabetic mouse model

Objective

This study aimed to identify significant differences in cochlea microvessel size between a diabetic mouse model (db/db) and normal mice using three-dimensional (3D) quantitative analysis.

Methods

Six control heterozygote db/+ as well as 18 male B6/BKS(D)-Leprdb/J (db/db) mice aged 14 (n = 9) and 28 (n = 9) weeks were examined. After clearing the cochlea, we reconstructed the 3D volumes of the spiral modiolar artery (SMA) in the cochlea using light-sheet microscopy and analyzed vessel wall thickness, cross-sectional area, short and long diameter, and vessel height.

Results

The average SMA-wall thickness in the db/db-mouse group (3.418 ± 0.328 μm) was greater than that in the control group (2.388 ± 0.411 μm). The average cross-sectional outer area, short diameter, and long diameter of the SMA in db/db mice were significantly larger than those in control mice (all p < 0.001). The cross-sectional areas increased with age (control: 221.782 ± 121.230 μm, 14 weeks; 294.378 ± 151.008 μm, and 28 weeks; 312.925 ± 147.943 μm).

Conclusion

The db/db mice had thicker and larger proximal-SMA vessel walls and diameters than control mice, respectively, thus potentially inducing increased blood viscosity or vascular insufficiency and aggravating hearing loss in type 2 diabetes mellitus.

Efficacy of Ginkgo biloba Extract Combined with Hormones in the Treatment of Sudden Deafness and Its Effect on the Reactivity of Peripheral Blood T Cell Subsets

This work was aimed at exploring the efficacy of Ginkgo biloba extract combined with hormones in the treatment of sudden deafness and the influence on the reactivity of peripheral blood T cell subsets (PBTCSs). In this work, 64 patients with sudden deafness who were treated in The First Affiliated Hospital of Hunan University of Traditional Chinese Medicine from August 2019 to August 2022 were selected as the research objects. The patients were randomly divided into a hormone group (treatment with prednisone acetate, n = 34) and a combination group (treatment with Ginkgo-Damole combined with prednisone acetate, n = 30). After the two groups of patients were treated in different ways, their efficacy, symptom improvement, changes in blood rheology, and PBTCSs were compared. The total effective rates (TERs) of the hormone group and the combination group were 76.32% and 95.73%, respectively (P < 0.05). The fibrinogen contents of the patients in the combination group were obviously lower than those in the hormone group after 5 d, 7 d, and 10 d of treatment (P < 0.05). The high blood viscosity (HBV) values of patients in the combination group at 5 d, 7 d, and 10 d after treatment were greatly lower than those in the hormone group (P < 0.05). The low blood viscosity (LBV) values after 3 d, 7 d, and 10 d of treatment in the combined group were much lower in contrast to those in the hormone group (P < 0.05). The CD3+, CD4+, and CD4+/CD8+ in peripheral blood in the combination group were sharply higher while the CD8+ in the combined group was lower in contrast to the hormone group (P < 0.05). There was no visible difference in the incidence of adverse reactions between the two groups of patients after treatment (P > 0.05). In conclusion, the combined application of Ginkgo biloba extract and hormones could effectively improve the abnormal hemorheological indexes of patients with sudden deafness and effectively relieve the imbalance of PBTCSs, which was safe.
