A new S2k AWMF guideline for the treatment of idiopathic facial palsy has been published. An accurate differential diagnosis is indispensable as 25-40% of all facial palsy cases are of non-idiopathic origin. It is explicitly recommended to treat patients with idiopathic facial palsy with steroids. Steroids favour a complete recovery, decrease the risk of synkinesis, autonomic sequelae and contractures. Adjuvant antiviral therapy cannot be recommended. On current data there is not sufficient evidence that the combination of steroids with antiviral drugs has a benefit for the patients.

Although biofilms are formed on a variety of surfaces, of utmost significance are those formed on prosthetic devices used as implants. Such biofilms can lead to severe device-related infections that are difficult to treat. In a search for new antibiofilm agents that can be used as "active" implant coatings, purified fraction from a tannin-rich extract of Terminalia chebula was isolated and tested for its antibiofilm properties on a titanium implant material.

Treatment of actual or impending pathologic fractures of the femur provides the senior author with some of the most rewarding surgical interventions of his practice. The patients' survival outlook is not changed, but their quality of life is enhanced significantly. Most health care providers usually provide the metastatic cancer patient only temporary symptomatic relief, at best, and often at the expense of continued pain, suffering, or sickness, such as is seen with chemotherapy-associated morbidity.

OBJECTIVE: implant placement Essure, sterilization procedure for women, were performed under hypnosedation (HYP) and compared to the operative anxiety and analgesia of 12 patients operated-on under general anesthesia (GA). STUDY DESIGN: prospective and comparative group study. PATIENTS AND METHODS: two groups of twelve patients were matched and compared based on the choice of anesthetic technique: hypnotics (HYP) with possible additional sedation by propofol and remifentanil or GA involving propofol, sevoflurane and remifentanil.

OBJECTIVE: To study the application of one-stage operation of ventriculo-peritoneal shunt and cranioplasty for hydrocephalus complicated by skull defect. METHOD: The clinical records of 54 patients with hydrocephalus complicated by skull defect treated with one-stage operation of ventriculo-peritoneal shunt and cranioplasty were reviewed in comparison with those of 30 patients receiving two-stage operations.

BACKGROUND: Developmentally regulated endothelial locus-1 (Del-1) is an extracellular matrix protein that is expressed by endothelial cells during embryological vascular development. We speculated that Del-1 may be reexpressed in ischemia and may be involved in endogenous angiogenesis. METHODS AND RESULTS: Del-1 protein was detected by immunohistochemistry in murine ischemic hindlimb after femoral artery excision. To determine whether exogenous Del-1 would augment angiogenesis in vivo, Del-1 or vehicle was administered for 3 weeks by intramuscular injection of murine ischemic hindlimbs.

A two-stage augmentation mammaplasty was performed on 231 patients (462 implants) over a period of 3 years. Two hundred and sixteen of the cavities (47 percent) were found to have hematomas at the time of the second surgical stage. After removal of the hematomas and completion of the second stage, only 41 breast (9 percent) developed capsular contracture. Treatment of the 41 with Diapulse therapy, massage, and closed capsulotomy completely eliminated all capsular contracture. The period of observation has ranged from 3 months to 2 1/2 years.

A balance control model was applied to interpret how subjects with a severe vestibular loss (VL) used vibrotactile information from a balance prosthesis to enhance balance control. Experimental data were from 5 VL subjects standing with eyes closed and responding to continuous pseudorandom surface tilts of the stance platform. Results showed that vibrotactile feedback information reduced sway at frequencies below ~0.6 Hz, but vibrotactile feedback was less effective in reducing sway as stimulus amplitude increased.

Vibrotactile feedback about body position and velocity has been shown to be effective at reducing low frequency body sway (below about 0.5 Hz) in response to balance perturbations while standing. However, current devices cause an undesirable increase in high frequency body sway. In addition, unlike other sensory prostheses such as hearing aids, which are fine-tuned to the user, current vibrotactile balance prostheses largely employ a "one size fits all" approach, in that they use the same settings (i.e. parameter values) for all subjects.
