OBJECTIVE: To assess word recognition and pitch-scaling abilities of cochlear implant users first implanted with a Nucleus 10-mm Hybrid electrode array and then reimplanted with a full length Nucleus Freedom array after loss of residual hearing. BACKGROUND: Although electroacoustic stimulation is a promising treatment for patients with residual low-frequency hearing,a small subset of them lose that residual hearing. It is not clear whether these patients would be better served by leaving in the 10-mm array and providing electric stimulation through it, or by replacing it with a standard full-length array. METHODS: Word recognition and pitch-scaling abilities were measured in 2 users of hybrid cochlear implants who lost their residual hearing in the implanted ear after a few months. Tests were repeated over several months, first with a 10-mm array, and after, these patients were reimplanted with a full array. The word recognition task consisted of 2 50-word consonant nucleus consonant (CNC) lists. In the pitch-scaling task, 6 electrodes were stimulated in pseudorandom order, and patients assigned a pitch value to the sensation elicited by each electrode. RESULTS: Shortly after reimplantation with the full electrode array, speech understanding was much better than with the 10-mm array. Patients improved their ability to perform the pitch-scaling task over time with the full array, although their performance on that task was variable, and the improvements were often small. CONCLUSION: 1) Short electrode arrays may help preserve residual hearing but may also provide less benefit than traditional cochlear implants for some patients. 2) Pitch percepts in response to electric stimulation may be modified by experience

OBJECTIVE: To assess the change in disease-specific quality of life (QOL) in pediatric patients with obstructive sleep-disordered breathing (OSDB) secondary to adenotonsillar hypertrophy after powered intracapsular tonsillectomy and adenoidectomy. DESIGN: Prospective outcomes study. SETTING: Hospital-based pediatric otolaryngology practice. PATIENTS: Fifty children with a mean age of 4.5 years who had a clinical diagnosis of OSDB. INTERVENTIONS: A caregiver of qualifying patients completed a validated QOL survey of pediatric obstructive sleep apnea, the OSA-18 (Obstructive Sleep Apnea-18), preoperatively and 3 months and 1 year postoperatively. MAIN OUTCOME MEASURE: The OSA-18 mean change scores. RESULTS: The mean (SD) total OSA-18 change score at the 3-month follow-up visit was 2.3 (1.2) and at the 1 year follow-up visit was 2.2 (1.3). The total and individual domain change scores were significantly improved at both postoperative intervals (P<.001 for all). There were no significant changes in the total or domain change scores between the intervals. The total change score was not significantly associated with either tonsil size or tonsil position. CONCLUSION: The OSDB-related QOL is significantly improved after powered intracapsular tonsillectomy and adenoidectomy, and this improvement remains stable even after 1 year

Manganese-enhanced MRI (MEMRI) has been developed to image brain activity in small animals, including normal and genetically modified mice. Here, we report the use of a MEMRI-based statistical parametric mapping method to analyze sound-evoked activity in the mouse auditory midbrain, the inferior colliculus (IC). Acoustic stimuli with defined frequency and amplitude components were shown to activate and enhance neuronal ensembles in the IC. These IC activity patterns were analyzed quantitatively using voxel-based statistical comparisons between groups of mice with or without sound stimulation. Repetitive 40-kHz pure tone stimulation significantly enhanced ventral IC regions, which was confirmed in the statistical maps showing active regions whose volumes increased in direct proportion to the amplitude of the sound stimuli (65 dB, 77 dB, and 89 dB peak sound pressure level). The peak values of the activity-dependent MEMRI signal enhancement also increased from 7% to 20% for the sound amplitudes employed. These results demonstrate that MEMRI statistical mapping can be used to analyze both the 3D spatial patterns and the magnitude of activity evoked by sound stimuli carrying different energy. This represents a significant advance in the development of MEMRI for quantitative and unbiased analysis of brain function in the deep brain nuclei of mice

The purpose of this article is to discuss the most significant oral health and related problems experienced by women, and to provide a Nurse's Plan of Action to respond to these largely preventable diseases. Oral health is integral to women's overall health and well-being, with poor oral health being associated with cancer, heart disease, diabetes, depression, and the birth of preterm, low-birthweight babies. Poor nutrition and lifestyle, principally tobacco and heavy alcohol use, can further increase the risk for oral diseases. Disparities are evident in women's reported poor access of regular dental care related to lack of dental insurance and low income. These facts are disturbing because most oral diseases are preventable. The Surgeon General's report on oral health in America (U.S. Department of Health and Human Services, 2000) and, more recently, the 'National Call to Action to Promote Oral Health' (U.S. Department of Health and Human Services, 2003) emphasized the need for partnerships of key stakeholders, including nurses, to get involved in oral disease prevention. Nurses are in an ideal position to provide health promotion education and screening across the multitude of settings in which they work regarding oral health and risk factors for oral disease. Nursing interventions aimed at promoting healthy outcomes and preventing disease should include a focus on oral health

BACKGROUND: Several unique complications of thyroidectomy exist because of its regional anatomy; they are well studied and reported. A majority of thyroidectomy patients report vague upper aerodigestive tract complaints. Despite this, no formal assessment of the integrity of the internal branch of the superior laryngeal nerve after thyroidectomy exists in the literature. METHODS: Thirty three patients undergoing thyroidectomy were prospectively evaluated with preoperative and postoperative laryngopharyngeal sensory testing. RESULTS: Preoperatively, 16 patients (49%) reported dysphagia, and 19 (58%) complained of globus sensation. Postoperatively, 24 (73%) patients complained of dysphagia, and 25 (76%) reported globus sensation. Preoperative sensory testing showed a mean sensory threshold of 2.79 +/- 0.51 mm Hg. The mean change in thresholds postoperatively was trivial (0.07 +/- 0.29 mm Hg), and did not differ significantly from zero (p = .19). CONCLUSIONS: Although most patients report significant difficulty swallowing after thyroidectomy, the sensory nerve to the laryngopharynx remains intact and is not at risk during thyroid surgery

Reconstruction of small and medium-sized defects of the nose poses a challenge to the facial plastic surgeon. Flaps for small to medium-sized defects most often are closed in single-staged procedures as opposed to larger-sized defects. A variety of techniques can be used including secondary intention, primary closure, full-thickness skin grafts, composite grafts, rhomboid flaps, bilobe flaps, dorsal nasal flaps, island flaps, and inferiorly based meliolabial flaps

OBJECTIVE: To review the background, case characteristics, and outcomes of malpractice litigation resulting from surgical injury of the spinal accessory nerve. DESIGN: Retrospective review of indemnity insurance cases (part 1) and court trials (part 2) between January 1, 1985, and January 1, 2007. In part 1, records of the Medical Liability Mutual Insurance Company identified 41 lawsuits in New York State; part 2 was a review of a national legal database (WestLaw) that identified 81 court trials. Case details were analyzed, and awards were adjusted for inflation. RESULTS: For part 1, of 41 indemnity insurance cases, 39 (95%) involved a posterior triangle lymph node biopsy. Defendants were mainly general surgeons and otolaryngologists. Most lawsuits against surgeons (22 of 34 [65%]) were settled before trial, and only 4 of 34 (12%) were discontinued. Of these 34 cases, 28 (82%) ultimately compensated the plaintiff. The mean inflation-adjusted pretrial settlement was $264 395, and the mean settlement at trial was $443 538. Cases reaching trial received significantly higher settlements (P = .01). For part 2, 81 cases of alleged surgical injury to the spinal accessory nerve were identified. Defendant physicians were mainly general surgeons and otolaryngologists. Most operations were cervical lymph node biopsies (55 [68%]), followed by sebaceous cyst excisions (6 [7%]), neck dissections (4 [5%]), and other procedures (12 [15%]). Morbidity included weakness (81 patients [100%]), pain (30 patients [37%]), inability to work (20 patients [25%]), need for a nerve repair procedure (16 patients [20%]), deformity (9 patients [11%]), and numbness (4 patients [5%]). Types of malpractice alleged included negligent surgical technique (79 cases [98%]), lack of informed consent (17 cases [21%]), and failure to diagnose the injury (16 cases [20%]). Thirty-seven cases (46%) were decided for the defendant, 32 (40%) were decided for the plaintiff, and 12 (15%) were settled (percentages do not total 100 because of rounding). The mean inflation-adjusted settlement was $356 132, and the mean jury award was $515 968. Jury awards were significantly higher than settlements (P = .003). CONCLUSIONS: Unintended injury to the spinal accessory nerve after head and neck surgery is a significant source of malpractice litigation. Timely diagnosis and treatment of this complication are essential. Regardless of whether the medical community considers careful surgical technique and nerve preservation to be the standard of care, the legal system clearly treats it as such, awarding compensation in 82% of cases. Strategies for optimal surgical care and litigation risk reduction are discussed

OBJECTIVE: To describe changes in disease-specific and global quality of life (QOL) for children with recurrent or chronic tonsillitis at 6 months and 1 year after tonsillectomy using two validated instruments, the Tonsil and Adenoid Health Status Instrument (TAHSI) and the Child Health Questionaire-PF28 (CHQ-PF28). STUDY DESIGN AND SETTING: A multicenter, prospective observational outcomes study. RESULTS: Ninety-two children, mean age (SD) 10.6 (3.4) years, enrolled with follow-up available for 58 children at 6 months and 38 children at 1 year. The children showed significant improvements in all subscales of the TAHSI including airway and breathing, infection, health care utilization, cost of care, eating and swallowing (all P < 0.001), and behavior (P = 0.01). Significant improvements were also found on several subscales of the CHQ-PF28, such as general health perceptions, physical functioning, parental impact, and family activities (all P < 0.001). CONCLUSION/SIGNIFICANCE: This uncontrolled study provides prospective evidence of improved disease-specific and global QOL in children after tonsillectomy
