PALATAL dysfunction, the term which describes both intermittent dorsal displacement of the soft palate and palatal instability, is one of the most commonly identified causes of upper airway obstruction in horses (Barakzai and Hawkes 2010). The reported prevalence of palatal dysfunction ranges from 10 to 20 per cent in young racehorses (Pollock and others 2009, Ducharme 2012). Dynamic endoscopic...

STATEMENT OF PROBLEM Preparation designs and ceramic thicknesses are key factors for the long-term success of minimally invasive premolar partial coverage restorations. However, only limited information is presently available on this topic. PURPOSE The purpose of this in vitro study was to evaluate the fracture resistance and failure modes of ceramic premolar partial coverage restorations wit...

JCO/FEBRUARY 2004 H retainers with Adams clasps or labial wires crossing the occlusion can create interferences that may lead to bruxism or disc displacement1-3 (Fig. 1). On the other hand, if a wraparound retainer is fabricated without crossover clasps, it is difficult to adapt the round wire closely enough to the anterior dentition to provide adequate mechanical retention, especially in patie...

Most acoustical researches consider palatality through languages dominated by the palatalization process, like Russian. In this paper, we propose to apply acoustical analysis, adapted to the dynamical character of the palatal sounds to the Danish language, which is exempt from any palatalization process and has no palatal phonemes, except [j]. In all cases, we can observe the setting up of a tr...

A 56-year-old man complained about a 6-year-history of gait disturbance and bilateral tinnitus. His neurological family history was unremarkable. Physical examination disclosed gait ataxia, slowly horizontal saccadic pursuit and a 2Hz frequency palatal tremor. Neuroimaging unveiled inferior olivary complex hypertrophy bilaterally and mild cerebellar atrophy (Figure), highly suggestive of progre...

The present study examines the role of transitional magnitude in the identification of consonant place. Transitions in the three vowels /u a e/ following the alveopalatal sibilant /ɕ/ in Polish were systematically manipulated and used as a gradient variable. In an identification task, native Polish speakers were given a choice between /ɕ/ and /ʂ/ for stimuli with varying levels of palatal trans...

We present two patients with acute myelogenous leukemia who developed palatal mucormycosis, as well as a review of 15 well described reported cases of the same condition in patients who had hematologic malignancy and had undergone hematopoietic stem cell transplantation. Early diagnosis of palatal mucormycosis requires high suspicion of the disease along with a thorough oral examination. Mucorm...

Palatal perforation can be defined as a communication between the nasal cavities and the oral cavity. There are various potential causes of palatal perforation. Failure of the palatal shelves to close during the sixth week of prenatal period results in cleft palate. Maternal alcohol consumption and cigarette smoking, folic acid deficiency, teratogenic drugs, certain viruses, corticosteroid use ...

Cellular and subcellular events during reorientation of the palatal shelf in hamster fetuses are described. An alteration in the morphology of the epithelial and the mesenchymal cells is observed during shelf realignment from a vertical to a horizontal plane. The mesenchymal cells elongate and subsequently appear to protrude in the medially bulging palatal shelf. Microtubules, microfilaments an...

BACKGROUND We peformed a ventral intermediate nucleus (Vim) thalamotomy in a patient with Holmes' tremor and palatal tremor. The frequencies of these movement disorders were 4 Hz and 3 Hz, respectively. Vim thalamotomy stopped the Holmes' tremor but not the palatal tremor. Our observations suggest different mechanisms for these two involuntary movements. CASE PRESENTATION A 57-arm 11 months a...
