The cause of objective tinnitus provoked by palatal and middle-ear myoclonus may be identified by magnetic resonance imaging of the central nervous system in the Guilliain-Mollaret triangle or it may be idiopathic. The idiopathic cases are rare. From the literature, one can perceive the following unanswered questions: (1) Are palatal and middle-ear myoclonus different entities […]

Depression is a mental state of depressed mood characterised by feelings of sadness, despair, and discouragement. Depression ranges from normal feelings of “the blues” through dysthymia to major depression. It in many ways resembles the grief and mourning that follow bereavement. There are often feelings of low self-esteem, guilt, and somatic symptoms such as eating […]

The auditory system has been the subject on studies of its capability to develop plastic responses to different kinds of lesions. Regeneration has been observed in the peripheral portions of the system, with neogenesis of hair cells in avians, sometimes followed by functional rehabilitation, with electrophysiological confirmation. It has been also noticed the ocurrence of […]

Advances in basic research in neurosciences and the introduction of new non-invasive techniques, that make possible the detection of weak signals of the brain, have revolutionized diagnosis and treatment. The most often used methods for functional imaging of the human brain are positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). More recently, a […]

Tinnitus is a common otological symptom. Usually it is subjective (perceived only by the patient); very rarely is it objective (heard by both the patient and the examiner). Objective tinnitus due to middle-ear myoclonus is extremely rare, with only a few case reports published in the literature. We present three cases of objective tinnitus caused […]

This reports recommends the consideration of development of additional outcome measures to be used as a battery of subjective self-assessment questionnaires for patients with tinnitus. The goal is improved overall care for the tinnitus patient. The name of the battery of outcome questionnaires is TOP. Five existing outcome measurements have been incorporated into the profile […]

At the Psychiatric Clinic of Szeged we began a comprehensive investigation with the aim of etiological sub-grouping of schizophrenia. As work hypothesis we treat schizophrenia as a progressive neurodevelopmental, multi-factorial long latency period disorder with notable genetic definiteness whose development and existence also significantly involves the influence of the environment. This disorder is heterogeneous clinically […]

In this work we describe the Verrucous Carcinoma characteristics in the external auditory conduct. It is an infrequent tumor in that area, with an apparently innocuous cytology but locally an invader. In describing the clinic of this pathology, the necessary complementary studies to reach a sure diagnosis, the deferential diagnosis that must be taken into […]

Aim of study: Hearing loss caused by exposure to recreational noise is considered a devastating disability, not least because it is virtually 100 percent preventable. No consensus exists regarding the magnitude of the risk. This study prospectively assesses the hearing threshold in a group of Portuguese adolescents, related to their habits of noise exposure. Method: […]

Masking of tinnitus is possible using high audio frequencies and low-frequency ultrasound. The mechanisms involved in reception and perception of both audio frequencies and ultrasound are identical, with the exception that ultrasound interacts with an intermediary site, the brain. We proposed brain ultrasonic demodulation as the means of place-mapping ultrasound on the first few millimeters […]
