A Review of Posterior Fossa Lesions.

Posterior fossa lesions can occur in patients of all ages. Patients present with subtle findings of hearing loss, tinnitus, headache, cranial neuropathies, imbalance, vertigo, nausea, and vomiting depending on the location and type of lesion. The presentation can be particularly insidious as the most common symptom is slowly progressive hearing loss.

The relationship between round window and ear canal Cochlear microphonic.

Hypothesis: Cochlear microphonic recorded at ear canal (CM-EC) can be a substitute for the one recorded at round window (CM-RW).

Background: Almost all clinics do not measure tone-burst evoked CM due to technical difficulty although it can provide more information than click evoked CM. Moreover, clinicians like the CM-EC more than that measured at CM-RW because CM-EC is non-invasive.

Optimizing the Measurement of 0.5-kHz Cubic Distortion Product Otoacoustic Emission.

Background: The measurement of low-frequency cubic distortion product otoacoustic emission, for example, 0.5-kHz cubic distortion product otoacoustic emission, is often severely affected by background noise, and currently 0.5-kHz cubic distortion product otoacoustic emission is not commonly applicable in clinical setting.

Sociodemographic correlates of occupational, recreational and firearm noise exposure among adults in the USA.

Objective: To determine sociodemographic factors associated with occupational, recreational and firearm-related noise exposure.

Methods: This nationally representative, multistage, stratified, cluster cross-sectional study sampled eligible National Health and Nutrition Examination Survey participants aged 20-69 years (n = 4675) about exposure to occupational and recreational noise and recurrent firearm usage, using a weighted multivariate logistic regression analysis.

Results: Thirty-four per cent of participants had exposure to occupational noise and 12 per cent to recreational noise, and 13 per cent repeatedly used firearms.

Imidacloprid alters ant sociobehavioral traits at environmentally relevant concentrations.

Much research has focused on the effects of neonicotinoids on honey bees, however, relatively few studies have investigated their effects on ants, a taxonomically-related eusocial insect of high ecological importance. This study quantified how dietary exposures to environmentally-relevant levels of a neonicotinoid insecticide (imidacloprid) affected foraging and nest building of the western harvester ant over 14 days. Using a replicated design, statistically-significant reductions in ant foraging success (50% or greater) occurred at concentrations as low as 50 ppb compared to controls.

Ultrasonic bone aspirator use in endoscopic ear surgery: feasibility and safety assessed using cadaveric temporal bones.

Objectives: To describe the feasibility and assess the safety of using an ultrasonic bone aspirator in endoscopic ear surgery.

Methods: Five temporal bones were dissected via endoscopic ear surgery using a Sonopet ultrasonic bone aspirator. Atticoantrostomy was undertaken.

Muscle-Nerve-Muscle Grafting for Facial Reanimation in Rats.

Objective: Facial paralysis is a devastating condition leaving patients with a myriad of aesthetic and functional consequences. Muscle-nerve-muscle (MNM) neurotization is a reinnervation technique that involves implanting an autogenous nerve graft as a conduit between an innervated "donor" muscle and a denervated "recipient" muscle. We investigated the use of MNM reinnervation, alone or in combination with electrical stimulation (ES) and testosterone propionate (TP) in comparison to nerve reanastomosis (RE), on functional recovery following rat facial nerve injury.

Neoplastic causes of nonacute facial paralysis: A review of 221 cases.

We conducted a retrospective review to assess the clinical presentation of patients with tumor-related nonacute complete peripheral facial weakness or an incomplete partial facial paresis and to provide an algorithm for the evaluation and management of these patients. Our study population was made up of 221 patients-131 females and 90 males, aged 14 to 79 years (mean: 49.7)-who had been referred to the Facial Nerve Disorders Clinic at our tertiary care academic medical center over a 23-year period with a documented neoplastic cause of facial paralysis.

Grading Facial Nerve Function Following Combined Static and Mimetic Surgical Techniques.

Objective To present a grading scale to assess the functional recovery of the facial nerve in patients who have undergone mimetic and static surgical techniques for facial reanimation. Study design This is a proposed new facial nerve grading system that will be demonstrated with specific case presentations. All patients underwent a variety of neural grafting, microvascular free-flap reconstruction, or surgical static procedures.

The Envoy Esteem implantable hearing system.

This article discusses the Envoy Esteem implantable hearing system, a completely implantable hearing device. The device is indicated for patients older than 18 years with stable moderate to severe sensorineural hearing loss and good speech discrimination. The device is placed through an intact canal wall tympanomastoidectomy with a wide facial recess approach.

Postlaryngectomy dysphagia masking as velopharyngeal insufficiency: a simple solution for an anterior neopharyngeal diverticulum.

Postlaryngectomy dysphagia is a common occurrence and can be a source of emotional distress that results in a decrease in quality of life among a patient population that is already exposed to considerable morbidity. One etiologic source that is less commonly reported as a source for postlaryngectomy dysphagia, and perhaps overlooked, is an anterior neopharyngeal diverticulum. Herein, we describe a postlaryngectomy dysphagia caused by a neopharyngeal diverticulum masking as velopharyngeal insufficiency of liquids.

Maths performance as a function of sex, laterality, and age of pubertal onset.

Sex differences in math/spatial performance demand explanations. Within the biological view, the complexity and number of variables make the explanation difficult at best. Laterality and age of pubertal onset have been investigated prominently in this context but rarely considered as interactions in the same study.

Sex, gender role, attribution of pathology, and handwriting tidiness.

An archival study sampled personality test protocols with spontaneous handwriting specimens from 73 men and 168 women for signatures and scores on selected scales from the Minnesota Multiphasic Personality Inventory-2. Judges applied a 5-point scale to sort signatures for tidiness. Interrater agreement was .

Nurturance. The spirit of holistic nursing.

In the theory of modeling and role modeling, the concept of nurturance is connected to holistic nursing practice. As nurturance is given and received within a context of unconditional acceptance, clients' needs are fulfilled and they can move toward a healthier state. An exploration of the literature revealed several defining attributes that clarify the definition of the concept as it is used by Erickson, Tomlin, and Swain.

Comparisons by sex of psychometric correlates of the MMPI-2 Depression Scale.

Scales of the Minnesota Multiphasic Personality Inventory-2 were correlated to identify which measures predicted depression among 219 women and 115 men. Despite prevalence data indicating that dysphoria is more common among females than males, sex did not predict MMPI-2 Depression scores in this sample. Masculine Gender Role was negatively predictive of depression for both sexes.

Type II errors in comparisons of dextral and sinistral groups.

Anomalous cerebral dominance can have multiple manifestations, e.g., left-eye preference or left-foot preference in the absence of left handedness per se.

Modeling and role-modeling theory: a case study of holistic care.

To provide holistic care, nurses must attempt to view the world through the clients' eyes. The Theory of Modeling and Role-Modeling (Erickson, Tomlin, & Swain, 1983) enables nurses to care for and nurture each client with an awareness of and respect for the individual's uniqueness. This type of care giving exemplifies theory-based clinical practice that focuses on the clients' needs.

Gender, gender role, and drawing skill.

Separate bodies of research suggest that performance in spatial reasoning covaries with gender and with gender role. Typically studies employ a spatial task whose variance is then used to account for differences in scores between gender groups or variance in a measure of gender role. A methodological issue in such research is that the tasks used to represent spatial reasoning may be differentially available or differentially appealing as a function of gender.
