[Q]: To investigate the surgical techniques and speech performance of multichannel auditory brainstem implant (ABI) in patients with bilateral acoustic neuromas (neurofibromatosis type 2).', 'The nucleus 21 channel auditory brainstem implant was implanted into the lateral recess of the fourth ventricle through the translabyrinthine approach in 7 patients after removal of the tumor. The accurate placement of electrode array was ensured by the electromyogram monitoring of the 7th and 9th nerves and the electrically evoked auditory brainstem responses (EABR). Initial switch-on occurred six weeks postoperatively. Speech evaluation was performed every 3 months for the first year and annually thereafter.', 'During the surgery, the lateral recess could be found and the typical EABR could be recorded in 6 cases. They later reported a significant benefit from the device. Two of the cases have achieved functional open-set speech understanding. In contrast, one patient with no EABR because of difficulty of the anatomic location during the surgery had no sensations postoperatively.

[Q]: This study aims to evaluate the relationship between serum thymus and activation-regulated chemokine (TARC) levels with various clinicopathological conditions in patients with drug eruptions. The value of TARC in diagnosing drug-induced hypersensitivity syndrome (DIHS) was also examined.', 'Study participants included 84 patients who presented with generalized eruptions suspected to be drug-related, including DIHS, Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), maculopapular exanthema (MPE), erythema multiforme (EM), erythroderma, and toxicoderma. The correlation coefficients between serum TARC levels and clinical parameters in peripheral blood samples were calculated.', 'Serum TARC levels in patients with DIHS were higher than those found in patients with SJS/TEN, MPE, EM, and toxicoderma. TARC levels had 100% sensitivity and 92.3% specificity in diagnosing DIHS, with a threshold value of 13,900\xa0pg/mL. Serum TARC levels positively correlated with age, white blood cell (WBC) count, neutrophil count, eosinophil count, monocyte count, atypical lymphocyte (Aty-ly) count, serum blood urea nitrogen (BUN) levels, and creatinine (Cr) levels. It negatively correlated with serum total protein (TP), albumin (Alb), and estimated glomerular filtration rate (eGFR). Among these clinical parameters, blood eosinophil counts were most strongly correlated with serum TARC levels, with a correlation coefficient of 0.53.

[Q]: Self-reported health-related quality of life (HRQL) and changes in HRQL have been shown to predict mortality and/or adverse events in patients with coronary artery disease. MacNew Heart Disease HRQL questionnaire scores were examined as predictors of 4-year all-cause mortality.', 'Following referral for angioplasty in 385 patients with coronary artery disease, data were analyzed for differences in all-cause mortality by MacNew Global and subscale baseline and 1- and 3-month change scores (deteriorated ≥0.50; unchanged (-0.49 to +0.49); and improved ≥0.50 points).', 'Mean baseline, 1-month, and 3-month MacNew Global and subscale scores were similar in survivors and non-survivors. Mean 1- and 3-month Global and emotional subscale and mean 1-month social subscale change scores decreased more in non-survivors than survivors. Compared with patients whose Global MacNew HRQL scores improved at one month, 4-year all-cause mortality hazard ratio (HR) was higher in patients whose HRQL deteriorated (HR, 1.70, 95% CI, 1.09, 2.65; p=0.021). Compared with patients whose Global MacNew HRQL improved at three months, 4-year all-cause mortality was higher in both patients whose HRQL had deteriorated (HR, 2.07, 95% CI, 1.29, 3.32; p=0.003) and patients with unchanged HRQL (HR, 2.62, 95% CI, 1.11, 6.17; p=0.028).
