The VSB, implanted using RW vibroplasty, is a safe and effective treatment for adults with conductive and mixed hearing losses who may have few, if any, other options.
The aims of this study are to report on our experiences using a bone paté (a mixture of bone dust and fibrin glue) fixation technique of the Combi 40/Combi 40+ electrode array during cochlear implant surgery. A retrospective study involving 57 patients implanted with Combi 40/Combi 40+ cochlear implants over 31 months fixated with bone paté was performed, utilizing our electrical fitting data as well as re-operation and X-ray findings. We found no signs of electrode retraction in any of the 57 patients. Electrical fitting data showed no reduction in the number of active channels between the first and last times patients were evaluated (a period of 4-31 months). Furthermore, a comparison of X-rays performed within the first week following cochlear implant surgery and again 7-27 months later showed no signs of electrode retraction in 10 patients. Three patients who required re-operations after implantation allowed us the opportunity to examine the effectiveness of the bone paté fixation and revealed new bone growth with the electrode fixed in place. Histological examinations of the newly built bone showed laminar and compact bone structures. The use of bone paté was thus found to be a suitable method of electrode fixation in cochlear implant surgery. Compared with other fixation methods, it is inexpensive and uses no foreign materials.
Accurate depiction of anatomic structures of the inner ear and cerebellopontine angle could be obtained by 3D T2-TSE only. The most accurate diagnosis in cases of pathology was provided by the combination of the 3D T2-TSE with unenhanced and enhanced 2D T1-weighted spin-echo sequences.
The goal of this report is to analyse the incidence of genital tumours in cattle referred to the Clinic between 2016 and 2019 and to describe the outcome after the surgical tumour resection. All cattle with a confirmed diagnosis of a genital tumour (n = 3) were included in the study. The breed, age, tumour localisation and type of treatment were considered. Telephone interviews were used to ask owners about the integration of the cows into the herd after discharge, the survival, the reason for leaving the herd, wound complications and tumour recurrence. Three genital tumours including a vaginal fibrosarcoma, vaginal leiomyosarcoma and luteoma were diagnosed. A tumour recurrence or metastasis did not occur. In conclusion, the tumour resection was successful in all three cases. To our knowledge, this is the first clinical description of a cow with a luteoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
