BACKGROUND THAP1 encodes a transcription factor (THAP1) that harbors an atypical zinc finger domain and regulates cell proliferation. An exon 2 insertion/deletion frameshift mutation in THAP1 is responsible for DYT6 dystonia in Amish-Mennonites. Subsequent screening efforts in familial, mainly early-onset, primary dystonia identified additional THAP1(More)

The modified barium swallow is currently the most comprehensive, widely available, and easily interpreted technique for the evaluation of patients with dysphagia by the head and neck surgeon. However, it requires the facilities, personnel, and use of a radiology suite, a trained speech pathologist, and exposure of the patient to radiation. It would(More)
Presented is a summary of our experience with 157 patients having a diagnosis of epidermoid cyst, glottic sulcus, or mucosal bridge of the true vocal cord. Each patient in this group was diagnosed and treated jointly by a phoniatrist and microlaryngoscopist and then evaluated for results of surgical and phoniatric therapy. Included in the discussion are(More)
Voice quality remains the issue often used to support preference for radiotherapy in treatment of early glottic cancer. We therefore conducted a perceptual voice study in 2 groups, one treated with radiotherapy for malignant disease and the other with narrow-margin laser cordectomy for either malignant or extensive benign lesions. Sequential patients, 12(More)
An extensive variety of THAP1 sequence variants have been associated with focal, segmental and generalized dystonia with age of onset ranging from 3 to over 60 years. In previous work, we screened 1114 subjects with mainly adult-onset primary dystonia (Neurology 2010; 74:229-238) and identified 6 missense mutations in THAP1. For this report, we screened 750(More)
A new, physical examination-based videoendoscopic method of evaluation can enhance considerably the understanding and efficiency of clinicians working with patients with swallowing difficulties. Using the fiberoptic nasolaryngoscope, evaluation of structure and function of palate, pharynx, and larynx, along with sensation of the laryngopharynx, is carried(More)
Scarring of the vocal folds can occur as the result of blunt laryngeal trauma or, more commonly, as the result of surgical, iatrogenic injury after excision or removal of vocal fold lesions. The scarring results in replacement of healthy tissue by fibrous tissue and can irrevocably alter vocal fold function and lead to a decreased or absent vocal fold(More)
To determine the varied causes of oropharyngeal dysphagia and their respective pathophysiology, a working understanding of the normal anatomy and function of the highly integrated mechanism of swallowing is outlined. This information is presented as the basis for a reasoned and detailed approach to the history, physical examination, and endoscopic(More)
