Fatigue behavior of highly porous titanium produced by powder metallurgy with temporary space holders.

Porous titanium cylinders were produced with a constant amount of temporary space holder (70 vol.%). Different interstitial contents were achieved by varying the starting powders (HDH vs.

Quantitative measurement of m-RNA levels to assess expression of cyclooxygenase-II, inducible nitric oxide synthase and 12-lipoxygenase genes in middle ear cholesteatoma.

To assess expression of three main inflammatory genes, COX-II, ALOX-12 and i-NOS, quantitatively at transcriptional level in cholesteatoma matrix tissue. Ten patients who have chronic otitis media with primary acquired cholesteatoma were included in this study. Tissue samples obtained from cholesteatoma matrix and external ear canal skin (control tissue).

The impact of carvedilol and metoprolol on serum lipid concentrations and symptoms in patients with hyperthyroidism.

Background: Hyperthyroidism is associated with unpleasant symptoms and hypertension due to increased adrenergic tone. Therefore, beta-blockers are often used in hyperthyroid patients. While some beta-blockers (such as propronolol and metoprolol) may have unwanted effects on lipid profile, carvedilol, a new alpha- and beta-blocker, has been suggested to have some metabolic advantages with respect to lipid profiles in hypertensive patients.

[Use of dehydrated temporal fascia in chronic otitis media surgery and tympanoplasty].

Objectives: We evaluated the use of homograft dehydrated temporal fascia (Tutoplast) in repair of tympanic membrane perforations secondary to chronic otitis media.

Patients And Methods: Dehydrated temporal fascia was used during tympanoplasty in 17 patients (10 females, 7 males; mean age 34 years; range 15 to 53 years) with chronic otitis media. Operations were type 1 tympanoplasty in six patients, tympanoplasty and mastoidectomy in three patients, and revision tympanoplasty and/or mastoidectomy in the remaining patients.

Mini-incision for pediatric cochlear implantation with a MED-EL device.

Objective: Minimal invasive approaches have been described for cochlear implantation. However, the number of reports about minimal invasive approaches for MED-EL devices is sparse. In this technical note, we describe our pediatric cochlear implantation and incision techniques for MED-EL devices.
