Palatal myoclonus is a rare condition in which there are rhythmic jerky movements of the soft palate and sometimes of the other muscles innervated by the brainstem A particularly annoying symptom is a rhythmic clicking sound in the ear due to the opening and closing of the Eustachian tube. Orofacial buccal dystonia is a focal dystonia with sustained spasms of the masticatory, facial or lingual ...

The purpose of this study was to evaluate the morphological structure of palatal rugae in Turkish orthodontic subjects with different sagittal skeletal malocclusions. Orthodontic dental casts of 105 patients (Class I [23 females, 12 males]; 35, Class II [18 females, 17 males]; and 35, Class III [14 females, 21 males] 10-22 years old) were analyzed for rugae patterns. Palatal rugae pattern and n...

Palatal rugae patterns have unique characteristics and have been proposed as an alternative method to establish identity when other means, such as fingerprints and dental records, are not attainable. This study was conducted to determine the morphological characteristics of palatine rugae and to assess the existence of side asymmetry in them in Sudanese Arabs. It also assesses the possibility o...

Background:Rugae are the anatomical folds that are located on the anterior third of palate behind the incisive papillae. They are also known as "Plica palatine," and the study of these patterns is called palatoscopy. It can be used in various fields such as sex determination, orthodontics and forensic odontology Aim And Objective:The objective of this article is to analyse different palatal rug...

A 67-year-old man presented with dysphagia and difficulty breathing. Physical examination revealed palatal myoclonus. In this patient, the respiratory difficulty was caused by the fragmentation of breathing. Electromyographic examination of the cricothyroid muscle demonstrated rhythmic myoclonic jerks. Magnetic Resonance Imaging (MRI) yielded a pontine midline and right sided tegmental infarct....

This is the first reported detailed electrophysiological study of diaphragmatic myoclonus. An 86 year old woman had rapid, intermittent epigastric pulsations. Neurological examination and imaging studies of the brain and spinal cord were normal. Needle EMG showed rhythmic contractions of the diaphragm and external intercostal muscles at 4 to 5 Hz. These contractions were often associated with s...

I n the brainstem of higher mammals there exists a very conspicuous and important tract linking the diensephalon to the inferior olivary nucleus. This system, that reaches its highest development in primates and man, was described for the first time by von Bechterew (1885) who called it “centrale Haubenbahn” indicating its origin and termination. It is a fact, however, that nowadays the origin ...

This study describes two patients who presented with intention tremor (IT) concomitant with olivary enlargement (OE), and discusses the relationship between these phenomena. Both patients had a vascular lesion in the brain stem, which subsequently caused IT and OE ipsilateral or contralateral to the site of the lesion, depending on the structures effected by the lesion. The results of our study...
