摘要:

The clinical records of 1,372 cases of otitis media with effusion (OME) treated during the past 10 years were reviewed in search of associations with sensorineural hearing loss (SNHL). In 14 cases (1.0 %), the development of SNHL was considered to be etiologically related to OME. These 14 cases were classified into two groups. In group A, which consisted of 5 cases, the clinical feature was acute onset of SNHL and gradual improvement. In group B of 9 cases, SNHL progressed gradually or insidiously and did not improve. Different pathophysiology may be assumed to underlie these two groups. The results of this study demonstrate that we have to pay attention to a possible development of SNHL during the course of OME.

摘要:

The role of disturbances of the iron metabolism (DIM) in idiopathic sudden hearing loss (ISHL) was investigated in 426 patients with ISHL who received iron therapy, anti-DIM medication, vitamins, and a combined regimen in a randomized study which was stratified by stages and groups. Low concentrations of haemoglobin, serum iron, serum ferritin, and red cell basic ferritin as well as abnormal circadian variations in the serum iron level were observed. The results were significantly better in patients receiving iron therapy than in those receiving anti-DIM medication, vitamins, and the combined regimen. Hearing improvement was achieved in 53.26% of the patients whose treatment started later than 3 months after the onset of the disease. The clinical association of DIM and ISHL is discussed.

摘要:

In routine clinical electronystagmographic (ENG) tests (postrotatory, optokinetic, caloric and tracking tests), eye movement signals were analyzed and a multiple discriminant analysis was carried out with the aid of a microcomputer. Six parameters were selected and, based on these, two functions for discriminating between peripheral and central disorders were established. Discrimination between 35 patients with peripheral lesions and 15 patients with central lesions was made with a correct classification rate of 97.1 and 86.7 %, respectively. These rates are significantly higher than that of any single ENG test analysis. Our results indicate that the clinical application of ENG can be improved by searching for more sensitive ENG parameters and adopting the comprehensive analysis approach.

摘要:

The authors investigated the tubal function by means of sequential scintigraphy in 16 patients affected by chronic otitis media and in 3 patients with posttraumatic perforation of the tympanic membrane. Evaluated parameters were: appearance time (AT), radioactivity peak time, rise time in the tympanic cavity, eustachian tube and rhinopharynx, and radioactivity percent values passed in the rhinopharynx. The tubal pressure-equilibrating function was determined by means of the manometer pump section of the impedance meter. A significant relationship between the pressure-equilibrating function and the tubal scintigraphy parameters has been detected. The variability of the AT in the tube and the almost constant time needed by the radioactive tracer to go through the tube and reach the rhinopharynx could indicate that a major role in the tympanic cavity drainage is played by the tympanic ostium and the surrounding mucosa.

摘要:

One of the reasons for failure of cartilage allografts is the impaired condition of the transplant during storage. In this paper we describe methods for the isolation and culture of viable chondrocytes obtained from nasal septum cartilage. Furthermore, we evaluate the possibility of growing such specific chondrocytes under culture conditions and storing them in a frozen state. Age dependent differences were observed in the growth rate of the cultured cells. Our results confirm that chondrocytes survive freezing and remain able to proliferate. Knowledge gained from this study may be applied to the culture and freezing of viable intact cartilage for use in reconstructive surgery in otolaryngology.

摘要:

The mammalian olfactory epithelium consists of supporting cells, olfactory receptor cells, basal cells and a fourth cell type, which has recently been discovered. In this study we examine this fourth cell type using immunohistochemical techniques. Anti-Purkinje-specifïc spot-35 protein (S-35), anti-S-100 protein (S-100), anti-neuron-specific enolase (NSE), antichromogranin A and antisynaptophysin antisera were used for the immunostaining. The fourth cell type immunoreacted only to anti-S-35 antiserum and did not react to other antisera in guinea pigs. On the other hand, in the human S-100 immunoreactivity was seen in the fourth cell type as well as weak reactivity to S-35. NSE immunoreactivity was found only in the olfactory receptor cells of guinea pigs and the human. From these results it is assumed that this fourth cell type is a second chemoreceptor different from the olfactory receptor cells because S-35 and S-100 are Ca++-binding proteins

摘要:

Unilateral cerebrospinal fluid (CSF) rhinorrhea as the only manifestation of the primary empty sella syndrome is a rare event. A case of a middle-aged male patient complaining for intermittent unilateral rhinorrhea, which started 5 months earlier, is reported. The persistence of this state was attributed to an allergic rhinitis. The initial work-up excluded the above diagnosis and an erroneous radiological diagnosis led to a puncture of the left maxillary sinus. A lateral X-ray of the skull and CT scan led to the diagnosis of empty sella syndrome, possibly due to an adenoma or a meningocele.

摘要:

In this randomized trial, 100 patients received ceftriaxone or amoxicillin-clavulanic acid in phlegmonous or abscess-forming ENT infections. Clinical and bacteriological results confirm that both antibiotics are equally effective, the advantage of ceftriaxone being one administration a day. Drainage surgery is necessary when an abscess has already formed. In 4 cases (ceftriaxone: 3; amoxicillin-clavulanic acid: 1), no positive response could be observed. Systemic and local tolerance was, as a general rule, excellent, and side effects were reported in 3 cases of the ceftriaxone group and in 3 cases of the amoxicillin-clavulanic acid group.
