Presbylarynx: is diabetes mellitus a risk factor for vocal atrophy? A prospective case-control study.

OBJECTIVE: To evaluate the prevalence of diabetes mellitus type 2 in subjects with presbylarynx. METHOD: A case-control, prospective study was carried out on consecutive subjects who presented to the otorhinolaryngology department. RESULTS: The study comprised 174 subjects (60 males and 114 females) with a mean age of 73.99 years (65-95 years). Presbylarynx was identified in 71 patients (41 per cent). Among patients with diabetes mellitus type 2, 20 patients (77 per cent) exhibited endoscopic signs of presbylarynx. A statistically significant difference was found between presbylarynx versus no presbylarynx concerning diabetes mellitus type 2 (p < 0.001). Subjects with diabetes mellitus type 2 were approximately eight times more likely to have presbylarynx compared to subjects without diabetes mellitus type 2. CONCLUSION: In this study, 77 per cent of patients with diabetes mellitus type 2 had endoscopic signs of presbylarynx. A multivariable analysis, which took into account co-morbidities of the elderly, identified diabetes mellitus type 2 as a possible risk factor for presbylarynx. Many physiopathological mechanisms might explain this result, as diabetes mellitus type 2 is known to affect muscular, neurological and vascular systems.

How do presbylarynx and presbycusis affect the Voice Handicap Index and the emotional status of the elderly? A prospective case-control study.

OBJECTIVE: To assess the influence of presbylarynx and presbycusis on Voice Handicap Index and emotional status. METHODS: A case-control, prospective, observational, cross-sectional study was conducted of patients aged 65 years or older referred to an otorhinolaryngology department from January to September 2020. Presbycusis was assessed by pure tone and vocal audiometry. Each subject underwent fibre-optic videolaryngoscopy with stroboscopy, and presbylarynx was considered when two or more of the following endoscopic findings were identified: vocal fold bowing, prominence of vocal processes in abduction, and a spindle-shaped glottal gap. Each subject completed two questionnaires: Voice Handicap Index and Geriatric Depression Scale (short-form). RESULTS: The studied population included 174 White European subjects, with a mean age of 73.99 years, of whom 22.8 per cent presented both presbylarynx and presbycusis. Multivariate linear regression revealed that only presence and severity of presbylarynx had an influence on Voice Handicap Index-30 scores. However, both spindle-shaped glottal gap and presbycusis influenced Geriatric Depression Scale scores. CONCLUSION: Presbylarynx has a strong association with the impact of voice on quality of life. Presbylarynx and presbycusis seem to have a cumulative effect on emotional status.

External auditory canal exostoses: long-term surgical satisfaction and its relationship with surgical complications.

OBJECTIVE: The main purpose of the present study was to evaluate whether complications related to surgery for exostoses are associated with a decrease in patients' quality of life. METHODS: This was a retrospective study for which the following information was collected: sex, age, pre- and post-operative symptoms, pre- and post-operative audiological evaluation results, surgical approach, instruments used, complications, and Glasgow Benefit Inventory score. RESULTS: The study included 67 patients (94 ears). The three main complaints reported were wax retention, otitis externa and hearing loss. Surgical complications occurred in 14.9 per cent of patients. Patients experienced a significant benefit from surgery, especially in relation to somatic state, with a global Glasgow Benefit Inventory score of + 44.3. No significant difference was found between the global Glasgow Benefit Inventory changes and surgery-related complications (p = 0.093). CONCLUSION: After surgery for exostoses, the vast majority of patients showed improvement. Complications related to surgery in general do not seem to influence patients' satisfaction with surgery.

Pig's ear: Streptococcus suis Meningitis and its associated inner ear implications.

Streptococcus suis (S. suis) is a zoonotic pathogen commonly found in Asian countries. Infection with this bacterium typically clinically presents as meningitis and individuals whom handle swine are at increased risk of developing infections. We present a case of a patient with a S. suis meningitis who worked as a butcher. The 48-year-old man was admitted to our department with headaches, fevers, nausea and bilateral hearing loss. According to his medical history, the patient had sustained a cut on his finger while preparing pork meat. A microbiological examination of the cerebrospinal fluid and blood revealed S. suis. The patient was empirically treated with ceftriaxone, vancomycin and dexamethasone. The patient made a complete recovery from the meningitic process and inflammatory markers. However, the hearing and vestibular loss persisted with considerable functional impact upon his daily life. He was elected for a right cochlear implant, 7 weeks after the presentation with a poor outcome. It is important to remember that inner-ear dysfunction can occur frequently in S. suis meningitis surviving patients. Physicians should have a high index of suspicion if risk factors are present and initiate urgent treatment to prevent serious long-term consequences.

Is von Willebrand disease linked to cholesteatoma aetiology?

Cholesteatoma is a common clinical picture seen by otolaryngologists. The disease is characterised by an abnormal grow "of skin in the wrong place". Specifically, in acquired cholesteatoma, the main causative issue is associated with ventilatory deficits within the middle ear and results in chronic infection. Molecular science has associated the presence of specific molecules with its development, and moreover recent research suggests that deregulated angiogenesis is a crucial process in the development of cholesteatoma and its recurrence. Further, haematologists have linked von Willebrand factor and its defects (both quantitative and qualitative) to augmented angiogenesis through upregulation of the vascular endothelial growth factor and angiogenic cytokines. Thus, herewith we probed whether a relationship between von Willebrand disease and the etiopathogenesis of cholesteatoma, plays a potential role for anti-angiogenic molecules for the advent of cholesteatoma surgery adjuvant treatment.
