Hearing rehabilitation of adults with auditory processing disorder: a systematic review and meta-analysis of current evidence-based interventions.

Background: For adults with auditory processing disorder (APD), listening and communicating can be difficult, potentially leading to social isolation, depression, employment difficulties and certainly reducing the quality of life. Despite existing practice guidelines suggesting treatments, the efficacy of these interventions remains uncertain due to a lack of comprehensive reviews. This systematic review and meta-analysis aim to establish current evidence on the effectiveness of interventions for APD in adults, addressing the urgent need for clarity in the field. Methods: Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic search across MEDLINE (Ovid), Embase (Ovid), Web of Science and Scopus, focusing on intervention studies involving adults with APD. Studies that met the inclusion criteria were grouped according to intervention with a meta-analysis only conducted where intervention, study design and outcome measure were comparable. Results: Out of 1,618 screened records, 13 studies were included, covering auditory training (AT), low-gain hearing aids (LGHA), and personal remote microphone systems (PRMS). Our analysis revealed: AT, Mixed results with some improvements in speech intelligibility and listening ability, indicating potential benefits but highlighting the need for standardized protocols; LGHA, The included studies demonstrated significant improvements in monaural low redundancy speech testing (p < 0.05), suggesting LGHA could enhance speech perception in noisy environments. However, limitations include small sample sizes and potential biases in study design. PRMS, Demonstrated the most consistent evidence of benefit, significantly improving speech testing results, with no additional benefit from combining PRMS with other interventions. Discussion: PRMS presents the most evidence-supported intervention for adults with APD, although further high-quality research is crucial for all intervention types. The establishment and implementation of standardized intervention protocols alongside rigorously validated outcome measures will enable a more evidence-based approach to managing APD in adults.

Effectiveness of the Auditory Temporal Ordering and Resolution Tests to Detect Central Auditory Processing Disorder in Adults With Evidence of Brain Pathology: A Systematic Review and Meta-Analysis.

Background: Auditory temporal processing tests are key clinical measures in order to diagnose central auditory processing disorder (CAPD). Although these tests have been used for decades, there is no up-to-date evidence to determine the effectiveness of detecting the abnormalities in central auditory processing in adults while the available national CAPD guidelines predominantly address CAPD in the pediatric population. Purpose: To determine the efficacy of the auditory temporal ordering tests [duration pattern test (DPT) and frequency pattern test (FPT)], and a temporal resolution test [gaps-in-noise (GIN) test] for detecting the central auditory processing abnormalities in adults with documented brain pathology. Research Design: Systematic reviews and meta-analyses. Study samples: Four databases, including PubMed, Web of Science, Embase, and Scopus, were systematically searched. The publications in the English language that recruited adults (above 16 years old) with pathologic brain conditions and described the diagnostic tests for auditory temporal processing were selected for review. Data Collections and Analysis: All data were systematically evaluated, extracted, categorized, and summarized in tables. The meta-analysis was done in order to determine the effectiveness of the DPT, FPT, and GIN tests. Results: The results showed significantly poorer performance of DPT and FPT, compared between participants with confirmed brain disease and normal controls, at the mean differences of percent correct -21.93 (95% CI, -26.58 to -17.29) and -31.37 (95% CI, -40.55 to -22.19), respectively. Subjects with brain pathology also performed poorer in GIN test at the mean difference of 3.19 milliseconds (95% CI, 2.51 to 3.87). Conclusion: The results from the meta-analysis provide evidence that DPT, FPT, and GIN clinical measures are effective in the diagnosis of CAPD in adults with neurological disorders. Poor performance on these tests is significantly related to the confirmed brain pathology. However, different units in results presentation and variety of testing strategies are limitations for this meta-analysis. The standard pattern of result reporting and international protocols test strategies should be developed in order to conduct better meta-analyses with a larger collection of suitable studies and less heterogeneity.

Single Cycle Versus Multiple Cycles of Canalith Repositioning Procedure for Treatment of Posterior Canal Benign Paroxysmal Positional Vertigo: A Randomized Controlled Trial.

OBJECTIVE: To compare the treatment outcomes and complications of single cycle versus multiple cycles of the canalith repositioning procedure (CRP). STUDY DESIGN: Randomized controlled trial. SETTING: Academic tertiary referral center; Chiang Mai University, Thailand. PATIENTS: One hundred and forty-three adults who had unilateral posterior canal benign paroxysmal positional vertigo (BPPV). INTERVENTION: Therapeutic. Patients received either a single cycle or multiple cycles of the CRP in one session. MAIN OUTCOME MEASURES: Rate of negative Dix-Hallpike test (DHT), rate of symptom improvement, dizziness handicap inventory score (DHI), and rate of complications. RESULTS: At the 1st week and the 4th week recall visits after CRP the treatment outcomes between the single-CRP group and the multiple-CRP group showed no significant difference. The outcomes included: 1) rate of negative DHT (1st week: 76.9 and 76.7%, 4th week: 89.5 and 88.2%); 2) rate of complete recovery or improved symptoms (1st week: 92.3 and 91.7%; 4th week: 96.5 and 98.0%); 3) DHI scores (1st week: 22 and 28; 4th week: 6 and 10); and 4) complication rate (1st week: 12.5 and 20%; 4th week: 20 and 0%. Rate of complications in the single-CRP group (6.9%) during the 1st treatment was lower than in the multiple-CRP groups (21.1%) (p-value = 0.013). CONCLUSION: A single cycle of CRP is as effective as multiple cycle CRP, with a lower incidence of complication and a decrease in the time for treatment. Single-cycle CRP is a more advantageous treatment for unilateral posterior canal BPPV. CLINICALTRIALS. GOV IDENTIFIER: NCT02701218.

Temporal bone involvement of IgG4-related disease: a rare condition misleading to petrous apicitis causing lateral rectus palsy.

IgG4-related disease (IgG4-RD) of temporal bone is rare and clinical manifestation mimics infection. A 19-year-old female presented with progressive left earache and intermittent left nasal obstruction. Then, she rapidly developed left lateral rectus palsy. The physical examination revealed mild redness of left tympanic membrane and a small nasal polyp from the left middle meatus. CT scan showed left petrous apicitis and enhancing sinonasal mucosa. Therefore, Gradenigo's syndrome was first considered. The empirical intravenous antibiotic was immediately prescribed and surgery was performed. The intraoperative pale soft tissue mass in middle ear and polyp in the left nasal cavity were sent for pathological examination and found positive immunohistochemical stains for IgG4 in plasma cells. Systemic corticosteroid, the first-line treatment, was started and her symptoms were finally recovery.

Localised nasopharyngeal amyloidosis: the importance of postoperative follow-up.

Localised nasopharyngeal amyloidosis is rare. Findings on physical examination and invasive pattern on CT scan can be misleading as it can resemble nasopharyngeal carcinoma. A 64-year-old man presented with left aural fullness for 6 months. The physical examination showed straw-coloured fluid in the left middle ear and irregular reddish mass at the left side of the nasopharynx. The CT scan showed a lobulated heterogeneous mass at the left side of the nasopharynx involving the left Eustachian tube opening. Pathology report was amyloidosis, thus, surgery was done. After a year, there were new foci of amyloidosis at the right side of the nasopharynx, and a repeat surgery was performed. Two years later, the systemic amyloidosis with underlying IgG4-related disease was suspected due to multiple organ involvement. Surgery is the treatment for localised amyloidosis with compressive symptoms. Close follow-up is important after surgical excision due to its recurrence and progression to systemic amyloidosis.
