Chinese and Japanese: The Changing Values of "Flexible Capital"

Our project hinged on the ability of the undergraduate advanced Chinese and Japanese students at the UIUC to describe, during short interviews, the value of their respective languages in economic terms. We found that the undergraduate students involved in learning third-year Chinese and Japanese were very well aware of the changing economic reasons for learning their languages. Our hypothesis that Japanese students were more motivated by popular Japanese media while the Chinese students were more motivated by economic reasons was borne out by our findings, though to say that our hypothesis was perfect would be a gross generalization not cognizant of the outlying data and the limitations of our project.unpublishe

Using Podcasts for Assessing Information Research

This paper reports on the use of podcast audio recordings to assess learning in a hybrid information research course. Evidence of learning that appeared in the audio recordings and how the project affected student learning were investigated. Findings suggest that student-created podcasts can be beneficial in that instructors can see what students learned from the podcast content; students can see evidence of own learning by looking at before and after podcasts; and that students see methods used by other students and reflect on own methods/knowledge

Malignant Melanoma metastacizing to the Thyroid Gland: A Case Report and Review of the Literature

Oral presentation 2006 AAO-H&NS Annual Meeting Toronto, Canada September 17-20, 2006. Objectives: The thyroid gland is a relatively uncommon site for secondary malignancy. Even lesscommon is metastasis of malignant melanoma to the thyroid gland. We present a case of malignantmelanoma metastatic to the thyroid gland presenting as thyroid enlargement. Study Design: This is a case report which utilizes chart review, intraoperative photographs,radiographic images, and pathology slides. Methods: A 68 year old patient with no prior evidence of primary skin melanoma presented witha neck mass which tested positive for melanoma. A year and a half following modified radical neckdissection, the patient presented with a diffusely enlarged thyroid gland from which fine needleaspiration revealed metastatic malignant melanoma. Results: A few months following this, the patient began having seizures and was found on MRIto have metastatic disease to the brain. He developed ventilator dependent respiratory failure andrequired a subtotal thyroidectomy for the placement of a tracheostomy tube. Conclusions: Patients with a history of malignancy and a thyroid nodule present a diagnosticdilemma—is it benign, a new primary, or distant metastasis? Review of this case and the literaturestrengthens the argument that any patient with a history of malignancy and a thyroid mass shouldbe considered as having metastasis until proven otherwise

A 3D benign paroxysmal positional vertigo model for study of otolith disease

AbstractObjectiveTo develop a three-dimensional study tool of the membranous labyrinth in order to study the pathophysiology, diagnostic workup and treatment of benign paroxysmal positional vertigo (BPPV). BPPV is the most common cause of peripheral vertigo. Its diagnosis and treatment depend on an understanding of the anatomy of the vestibular labyrinth and its position relative to the head. To date, many illustrations have been made to explain principals of diagnosis and treatment of BPPV, but few have been based on anatomical studies of the membranous labyrinth.MethodsA cadaveric human membranous labyrinth was axially sectioned at 20 μm resolution, stained and segmented to create a high-resolution digital model. The model was cloned to create an enantiomeric pair of labyrinths. These were associated a 3D model of a human skull, segmented from MRI data, and were oriented according to established anatomic norms. Canal markers representing otoliths were created to mark canalith position during movement of the model within the 3D environment.ResultsThe model allows visualization of true membranous labyrinth anatomy in both ears simultaneously. The dependent portion of each semicircular duct and of the utricle can easily be visualized in any head position. Moveable markers can mark the expected progress of otolith debris with changes in head position and images can be captured to document simulations. The model can be used to simulate pathology as well as diagnostic maneuvers and treatment procedures used for BPPV. The model has great potential as a teaching tool.ConclusionA simple model based on human anatomy has been created to allow careful study of BPPV pathophysiology and treatment. Going forward, this tool could offer insights that may lead to more accurate diagnosis and treatment of BPPV

Malignant melanoma metastatic to the thyroid gland: a case report and review of the literature.

The thyroid gland is a relatively uncommon site for a secondary malignancy; even less common is a case of malignant melanoma metastatic to the thyroid. We describe the case of a 68-year-old man who presented with a neck mass in the posterior triangle. Fine-needle aspiration biopsy (FNAB) identified the mass as a malignant melanoma. The patient had had no known primary skin melanoma. He underwent a left modified radical neck dissection, and the mass was discovered to be a positive lymph node. Postoperatively, he declined to undergo radio- and chemotherapy. Eighteen months later, he returned with a diffusely enlarged thyroid. FNAB again attributed the enlargement to malignant melanoma. Soon thereafter, the patient began experiencing seizures, and on magnetic resonance imaging, he was found to have metastatic disease to the brain. He developed ventilator-dependent respiratory failure and required a subtotal thyroidectomy for the placement of a tracheostomy tube. Patients who present with a thyroid nodule and who have a history of malignancy present a diagnostic dilemma: Is the nodule benign, a new primary, or a distant metastasis? The findings of this case and a review of the literature strengthen the argument that any patient with a thyroid mass and a history of malignancy should be considered to have a metastasis until proven otherwise

Treatment of Endovascular Coil and Stent Migration Using the Merci Retriever: Report of Three Cases

Background. Coil and stent migration is a potentially catastrophic complication in endovascular neurosurgery, which may lead to cerebral thromboembolism. Techniques for removing migrated coil and stent are not well established. Methods and Results. We present three cases in which coil or stent migration occurred during endovascular embolization of a cerebral aneurysm. The Merci Retrievers were used successfully in all cases to remove the displaced foreign bodies. Technical details are described. Conclusion. The Merci Retriever device can be utilized successfully for removal of migrated coils and stents in endovascular neurosurgery
