Evaluation of Two Spectro-Temporal Ripple Tests and Their Relation to the Matrix Speech-in-Noise Sentence Test in Cochlear Implant Recipients.

Objectives: Spectro-temporal ripple tests are commonly used in cochlear implant (CI) research as language-independent indicators of speech recognition (in noise) or as stand-alone tests. Test-retest reliability of these tests has been scarcely documented. We evaluated the test-retest reliability of spectral-temporally modulated ripple test (SMRT) and spectro-temporal ripple for investigating processor effectiveness (STRIPES) and correlated their findings to the Dutch/Flemish Matrix speech-in-noise sentence test (MST) in CI recipients.

Dynamic Current Focusing Compared to Monopolar Stimulation in a Take-Home Trial of Cochlear Implant Users.

Objectives: This study compared the performance of a dynamic partial tripolar cochlear implant speech encoding strategy termed dynamic current focusing (DCF) to monopolar stimulation (MP) using spectro-temporal, temporal, and speech-in-noise recognition testing.

Design: DCF is a strategy that utilizes tripolar or high partial tripolar stimulation at threshold level and increases loudness by slowly widening current spread towards most comfortable level. Thirteen cochlear implant users were fitted with DCF and a non-steered MP matched on pulse rate, pulse width, and active electrodes.

Short term safety of oncoplastic breast conserving surgery for larger tumors.

Background: Oncoplastic surgery (OPS) replaces lumpectomy as standard technique in breast conserving surgery (BCS). OPS has shown to give good cosmetic results, but is it as safe as standard lumpectomy? We conducted a retrospective cohort study to determine postoperative complications, resection margins and re-excision rates for OPS compared to standard lumpectomy.

Methods: Based on data from the 'Netherlands Cancer Registry' and medical records we scored patient, treatment and follow-up related variables.
