OBJECTIVES To evaluate the audiometric results of primary stapes surgery in patients with otosclerosis and to determine predictors of a postoperative air-bone gap (ABG) of 10 dB or less and a postoperative gain in air conduction (AC) exceeding 20 dB. DESIGN Retrospective cohort study. SETTING Tertiary referral center in Utrecht, the Netherlands. PATIENTS Nine hundred thirty-nine patients ...

Ascorbigen (ABG) belongs to the glucosinolate family and occurs mainly in Brassica vegetables. It is formed by its precursor glucobrassicin. Glucobrassicin is enzymatically hydrolyzed to indole-3-carbinol, which in turn reacts with L-ascorbic acid to ABG. The degradation of glucobrassicin is induced by plant tissue disruption. The ABG formation depends on pH and temperature. The degradation of ...

OBJECTIVE The emergency departments (EDs) of Chinese hospitals are gradually being equipped with blood gas machines. These machines, along with the measurement of biochemical markers by the hospital laboratory, facilitate the care of patients with severe conditions who present to the ED. However, discrepancies have been noted between the Arterial Blood Gas (ABG) analyzers in the ED and the hosp...

Objective: The perichondrium cartilage graft has its advantage not only on hearing outcome but also in graft uptake rate. So, the main aims are to compare the pre and post-operative hearing results and to observe the graft uptake rate. Materials and methodology: This is a prospective, longitudinal and analytical study conducted in the department of otorhinolaryngology in Kathmandu university ho...

The problem of Authenticated Byzantine Generals (ABG) aims to simulate a virtual reliable broadcast channel from the General to all the players via a protocol over a real (point-to-point) network in the presence of faults. We propose a new model to study the self-composition of ABG protocols. The central dogma of our approach can be phrased as follows: Consider a player who diligently executes ...

Objectives: To evaluate the anatomical and audiological out­ comes of synchronous ossiculoplasty with ossicular replace­ ment prosthesis during canal wall down mastoidectomy for advanced cholesteatoma. Methods: The prospective study was done at a tertiary referral institute included 30 patients of cholesteatoma who underwent canal wall down mastoidectomy. Ossicular reconstruction was performed ...

OBJECTIVES To determine whether ossicular reconstruction (OCR) performed concurrent with tympanomastoidectomy for cholesteatoma results in significantly different hearing results when compared to OCR performed in a separate, staged procedure. STUDY DESIGN Retrospective. MATERIALS AND METHODS Study subjects were patients undergoing OCR within a 2-year period. Intervention was OCR concurrent ...

PURPOSE OF THE STUDY Hydroxypatite coating (HAC) was introduced into total hip arthroplasty (THA) practice to improve the fixation interface between bone and prosthesis. To test this assumption however, long-term follow-up investigations are needed. In this study, we present data for two consecutive series of THA stems with HAC and a minimum ten-year follow-up. MATERIAL Overall, 249 patients (2...

OBJECTIVE The primary objective is to report long-term hearing outcomes (>2 years) after titanium ossiculoplasty in patients with chronic otitis media. STUDY DESIGN Case series with chart review. SETTING Tertiary care hospital. SUBJECTS AND METHODS In total, 156 patients with chronic otitis media undergoing titanium ossiculoplasty were included. The primary outcome measure was the long-te...

OBJECTIVES/HYPOTHESIS To review surgical findings and hearing outcomes of incus footplate assembly (IFA) for the patients with conductive hearing loss due to missing stapes superstructure with a mobile stapes footplate. STUDY DESIGN Retrospective case review and survey. METHODS Pre- and postoperative audiometric data and intraoperative findings were reviewed. Postoperative air-bone gap (ABG...
