Transduction of the contralateral ear after adenovirus-mediated cochlear gene transfer. (1/8)

Cochlear gene transfer is a promising new approach for inner ear therapy. Previous studies have demonstrated hair cell protection with cochlear gene transfer not only in the inoculated, but also in the uninoculated ear. To characterize the kinetics of viral spread, we investigated the extent of transgene expression in the contralateral (uninoculated) cochlea after unilateral adenoviral cochlear gene transfer. We used a lacZ reporter gene vector, and demonstrated spread of the adenovirus into the cerebrospinal fluid (CSF) after cochlear inoculation of 25 microl viral vector. Direct virus application into the CSF resulted in transduction of both cochleae, whereas virus inoculation into the bloodstream did not. The cochlear aqueduct was identified as the most likely route of virus spread to the contralateral cochlea. These data enhance our understanding of the kinetics of virus-mediated transgene expression in the inner ear, and assist in the development of clinical applications for inner ear gene therapy. Our results showed a functional communication between the CSF and the perilymphatic space of the inner ear, that is not only of importance for otological gene transfer, but also for CNS gene transfer.

MR cisternography of the cerebellopontine angle: comparison of three-dimensional fast asymmetrical spin-echo and three-dimensional constructive interference in the steady-state sequences. (2/8)

BACKGROUND AND PURPOSE: MR cisternography has been used as the noninvasive screening tool of the cerebellopontine angle. The purpose of this study was to directly compare two currently dominant types of sequences for heavily T2-weighted MR cisternography. METHODS: Three-dimensional fast asymmetric spin-echo (3D-FASE) sequences, which are 3D half-Fourier rapid acquisition with relaxation enhancement and 3D constructive interference in the steady-state (3D-CISS) sequences, were compared on a clinical 1.5-T MR unit using the same scan times. In five healthy volunteers, the contrast-to-noise ratio (C/N) between CSF and the cerebellum was measured at three locations. Then, for qualitative analysis, the quality of the labyrinth was scored on the original source multiplanar reformatted images, the virtual endoscopic images, and the maximum intensity projection (MIP) images. In 20 consecutive patients with suspected cerebellopontine angle tumors, visualization of the tumors was evaluated using 3D contrast-enhanced spoiled gradient-echo imaging as the standard of reference. RESULTS: Both sequences showed comparable mean C/N values; however, in qualitative analysis, the scores for 3D-CISS on the source, virtual endoscopic, and MIP images were significantly lower than those on the images obtained with 3D-FASE, owing to more prominent flow and magnetic susceptibility artifacts on the 3D-CISS sequences. In all subjects, discontinuity of the semicircular canals was seen on the virtual endoscopic and MIP images obtained with 3D-CISS, owing to susceptibility artifacts, but not on those obtained with 3D-FASE. All 12 tumors were detected by both sequences, but 3D-CISS gave one false-positive result. CONCLUSION: 3D-FASE is considered the method of choice because artifacts are reduced and specificity is increased.  (+info)

Persistence of perilymph fistula mechanism in a completely paretic posterior semicircular canal. (3/8)

The three dimensional eye movements (search coil technique) of a patient with a completely paretic left posterior semicircular canal as a result of a perilymph fistula (PLF) were studied. The patient still exhibited pressure induced nystagmus that obeyed Ewald's first law. This finding cannot be explained by otolith stimulation, but might indicate that PLF mechanisms either persist in canal plugging or act on the ampulla by directly deflecting the cupula.  (+info)

Cochlear aqueduct flow resistance depends on round window membrane position in guinea pigs. (4/8)

The resistance for fluid flow of the cochlear aqueduct was measured in guinea pigs for different positions of the round window membrane. These different positions were obtained by applying different constant pressures to the middle ear cavity. Fluid flow through the aqueduct was induced by small pressure steps superimposed on these constant pressures. It was found that the resistance for fluid flow through the aqueduct depended on the round window position but not on flow direction. The results can be explained by special fibrous structures that connect the round window with the entrance of the aqueduct. It was also found that the equilibrium inner ear pressure depends on middle ear pressure, indicating that the aqueduct does not connect the inner ear with a cavity with constant pressure.  (+info)

How does the urodele ear develop? (6/8)

An overview is provided of the structural and molecular events causing the transformation of undifferentiated epidermal cells together with the underlying mesenchyme to become the complex, three-dimensional ear. While tremendous progress has been achieved in a few model systems, enough is not yet known about the comparative embryology of ear development to provide causal explanations of the adult structural differences among species. It is hoped that the changes in selector and/or structural genes, as well as changes in the spatiotemporal induction of structural gene activation, and possible changes in the interaction between the various embryonic sources which contribute to the ear, will soon be understood. The most promising new avenue for research appears to be studies which combine classical transplantation tissue experiments with modern gene expression analyses and modern in vitro assays of the role of putative morphogens or trophic factors. It is emphasized that it is not understood what is missing in the developmental program of those salamanders which have lost a basilar papilla. Direct comparison of gene expression patterns and xenoplastic transplantations in salamanders of comparable stages which either do or do not develop this organ should help to clarify the molecular events that have led to this major evolutionary novel feature of the vertebrate ear.  (+info)

Enlarged cochlear aqueduct. (7/8)

Enlargement of the cochlear aqueduct is a controversial topic, with experienced investigators doubting its existence because of a lack of published cases. We describe the CT appearance of an enlarged cochlear aqueduct in a patient with advanced congenital inner ear anomalies and congenital hearing loss. The intent of this article is to present the CT appearance of a presumably enlarged cochlear aqueduct and to underscore the need to examine this structure in patients with congenital hearing loss.  (+info)

Sudden hearing loss: frequency of abnormal findings on contrast-enhanced MR studies. (8/8)

BACKGROUND AND PURPOSE: Our purpose was to determine the frequency of abnormal findings on contrast-enhanced high-resolution MR imaging studies in patients with sudden hearing loss. METHODS: Seventy-eight consecutive patients with sudden hearing loss underwent contrast-enhanced MR imaging of the temporal bone, cerebellopontine angle, and brain. Additional tests included audiologic examination, electrocochleography, fistula tests, and serologic tests for viral agents and autoimmune disorders. RESULTS: Probable causes of the sudden hearing loss in these patients included viral or immune-mediated disease, Meniere disease, vascular disorder, syphilis, neoplasm, multiple sclerosis, and perilymphatic fistula. Twenty-four (31%) of the 78 patients were found to have abnormal imaging results early in the course of their work up and treatment. CONCLUSION: The prevalence of abnormal findings on contrast-enhanced MR studies is higher than previously reported in patients with sudden hearing loss.  (+info)

Definitions of sudden hearing loss have been based on severity, time course, audiometric criteria, and frequency spectrum of the loss. Abrupt as well as rapidly progressive losses have been included under a single definition of sudden hearing loss.
Intracranial fluid pressure is measured as a function of a characteristic or characteristics of an eardrum. Either or both of the displacement of the eardrum when the stapedius muscle is stimulated or the aural acoustic compliance of the eardrum is measured and provided the cochlear aqueduct is open this will give an indication of intracranial fluid pressure without surgery. Acoustic compliance is measured under conditions of tympanometry but the tympanometry facility is disabled during displacement measurement. The data obtained by the method of the invention may be compared with reference data obtained from the same patient or in clinical trials to provide a real-time record of intracranial fluid pressure changes. Preferably eardrum displacement is used as a baseline measure and acoustic compliance measurement records short-term variation, the two records being combined by computer. Reference data may be input to the computer to update the information displayed. This reference data may include known

Sudden hearing loss is a rapid loss of hearing in one or both ears which can happen to an individual all at once or over a period of up to 3 days. Usually, patients report that their ear feels full or blocked. Dr. Stachler notes that as symptoms of sudden hearing loss are so prevalent and non-specific, evaluation and treatment are often delayed in several cases. Sudden hearing loss can be caused by a range of issues, such as infectious diseases, induced hearing loss, head trauma, noise induced hearing loss, Menieres disease, and circulatory problems..

What is the first sign of hearing loss? Most complain that people mumble or talk too fast. Hearing loss is often accompanied by tinnitus. A buildup of earwax, medication, exposure to loud sounds and hearing loss can all cause ringing in the ears, or tinnitus. The ringing might be constant or occasional, but it is often the first sign of hearing loss. Is sudden hearing loss an emergency? Not all sudden hearing losses are necessarily a really bad sign, the problem is that it could be, so therefore you should treat it as such. SSHL is, and should be treated as a medical emergency when it occurs. When any sudden onset hearing loss occurs, the faster you get it checked, the better the outcome may be for your hearing. If it is SSHL, the faster you get treatment, the better it will be for your long term ability to hear.

Many posters including yours truly, have discussed the Big A versus Belmont Park developments for some time now.

The NYRA hasnt ever had any real qualms about not having to race in the freezing cold at Aqueduct, knowing some provision for a shorter late fall-early spring meet would be made at Belmont. An astute political move was to make it look like Delaware North was going to pay a ton of money to develop the Big A, then when they defaulted or tried to modify the deal, the discussion of just doing one grand palace at a downstate racetrack could gain some momentum once again, and as a last ditch concession to the Aqueduct community if necessary, bring in a vendor to hang some machines on ...

Primary pulmonary neoplasms have been reported to occur predominantly in dogs over seven to eight years of age. The results of this study support this finding. No sex or breed predisposition to primary lung tumors have been identified. In this study, males and females were represented equally. Although no one breed was affected more frequently than others in this study, all of the dogs were medium to large size breeds with the exception of case #3. Further case studies were necessary to determine if this is either a significant trend or because of the predominance of medium to large breed dogs within our referral population.. Clinical signs associated with primary pulmonary neoplasia are often vague and nonspecific. It has been reported that as many as 33 percent of primary lung tumors are discovered during a physical or radiographic evaluation for another problem. There were no abnormal findings on physical examination in four of the 14 dogs (29 percent) in this study.. The most common clinical ...

The CIA uses these so-called chimeras for various undercover operations, and one of their technicians, Simon Boyle, has a sideline making illegal copies: chimeras based on famous criminals, for rent. His Billy the Kid, a creation unable to comprehend or sometimes even recognize the sorts of things that didnt exist before the 1880s and endowed with powerful sex pheromones, is quite popular for a night of historically convincing passion with rich women, particularly the part where Boyle (as sheriff Pat Garrett) guns him down. As the story progresses, Billy the Kid starts remembering things from his previous lives. One of Boyles clients sets Billy loose into the mean streets of the 21st century, where he struggles to seize control of the myths in his ROM. Jane, a worker in a ...

OBJECTIVES: The objectives of this study were to describe the clinical course and outcome of patients with sudden sensorineural hearing loss (SSNHL) in conjunction with benign paroxysmal positional vertigo (BPPV), and hypothesize the possible pathophysiology of this entity.. STUDY DESIGN: Retrospective study of all patients with evidence of SSNHL with any type of BPPV between 2008 and 2012.. SETTINGS: Tertiary care university hospital.. SUBJECTS AND METHODS: Five patients aged 56 to 71 were diagnosed with unilateral profound SSNHL and BPPV. Neurotologic examination revealed an ipsilateral torsional, up-beating nystagmus on Dix-Hallpike exam. Severe or profound ipsilateral-sensorineural hearing loss was recognized on audiometry. The rest of the exam was normal; this was in keeping with the diagnosis of SSNHL with ipsilateral posterior semicircular canal BPPV.. RESULTS: All patients were treated with a modified Epley maneuver; oral steroids were administered for two weeks. In all cases vertigo ...

Leptomeningeal carcinomatosis is a rare entity caused by metastases from solid tumors in the form of diffuse seeding to the leptomeninges. Lots of neurologic symptoms related to cerebrum, cerebellum, spinal root, and cranial nerves can be occurred in leptomeningeal carcinomatosis patients. It is not often that only bilateral hearing loss is present as the initial clinical symptom. In this report, we present a 54-year-old man represented with sudden bilateral hearing loss and vertigo who were operated for duodenal adenocarcinoma six months before. The clinical, radiologic, and cerebrospinal fluid cytologic features of the patient and the case reports of sudden hearing loss related to leptomeningeal carcinomatosis are discussed. ...

A study using Taiwanese medical insurance records suggests sudden loss of hearing might be an early sign of vulnerability to stroke, researchers say. Hearing loss can foreshadow a cerebrovascular event by as much as two years, the study published in Stroke: Journal of the American Heart Association found. Lead investigator Herng-Ching Lin, a professor at Taipei Medical University School of Health Care Administration, says five-year follow-up data on 1,423 patients hospitalized for an acute episode of sudden sensorineural hearing loss showed they were more than 1 1/2 times more likely to suffer a stroke than a control group of 5,692 patients who had been hospitalized for an appendectomy. However, because insurance records may not have contained reliable information, such as correct diagnostic codes or other factors, the findings should be considered tentative, Lin says. To the best of our knowledge, no study has investigated the incidence or risk of cerebrovascular diseases developing following ...
As this case report demonstrates, there is only a partial and transient beneficial effect of ERT and hyperbaric oxygen treatment combined with corticotherapy and pentoxifylline for hearing loss in patients with FD. As there is no international consensus on treatment of SHL [12] (particularly in patients with FD), the administered therapy is the standard therapy for SHL, and the results obtained in our case were at their best for the first treatment course, whereas partial regression of the symptoms occurred on the second occasion. Although SHL in patients with FD is rarely described, the symptoms are consistent with the vascular alterations caused by the disease in other areas. The incidence of SHL may be underestimated.. The mechanism of progressive SHL in patients with FD remains unclear. It has been suggested that globotriaosylceramide accumulation in vascular endothelium, decreased numbers of spiral ganglion cells [13], long-term obstruction of cranial vessels by dolicho-ectasic arteries ...
Sudden hearing loss is not a common occurrence, but more often it develops gradually, till the patient fails to notice that they are missing out subtle everyday sounds such as a ticking clock or a rustling newspaper, currency etc. By the time its moderate to severe, the patient finds its difficult to comprehend or follow speech which is often noticed by the patients family members and close aids, who had to repeat to make them heard. ...

The other take-home message from your friends experience is to get an evaluation from an otolaryngologist (Ear, Nose and Throat doc-but if you put it in Greek or Latin we feel more special) for any sudden hearing loss. Sad to say, we see many that are misdiagnosed for months as allergies or fluid. And its sometimes tough to have to say to a patient, we might have been able to do something about your hearing if we could have seem you in the first week or two. Tumors causing hearing loss are rare, but Ive diagnosed about 10 of them in the last 15 years. Fortunately, they are usually benign and slow growing--but in a lousy spot. They are somewhat related to neurofibromatosis II, but thats even rarer (and familial ...

Which is to say, Flaubert saw himself as encompassing all that there is. And not only that: he feels he is in danger of having his knowledge of life, the world, and the ages of history, compromised by contact with the world: this is the reason he needs to live in isolation to serve his art. & so in another letter, he characterizes himself as a man of wax; everything gets imprinted on him [he is speaking of himself i the third person], is encrusted on him, penetrates him. If I should visit you, I should think of nothing but you and yours, your house, your country, the appearance of the people I had met, etc. In a related vein, a few weeks later he casually writes, I must not give myself a week of holiday; that is why I do not go to Nohant [to visit Sand].
