[Progress in rehabilitation of dizziness and equilibrium disorders].

Physiopathological basics of vestibular rehabilitation are based on mechanisms of vestibular compensation. In the course of vestibular organ lesion compensation can be achieved sooner through increased activity of the patient in habituation process, with active contribution of the vision and proprioceptive organs. The criteria of qualification and preparation of the patients were presented. The role of creation of adequate motivation of the subject in the process of preparation was emphasised. The progresses that had been achieved in this treatment method were mentioned. The value of individual training programs, that is programs adapted to definite needs of the patients, was appreciated in recent years. It was revealed, that training programs directed to train certain system such as lower limbs strength, failure of vestibular receptor, gait disturbances bring significant improvement in such cases. However traditional exercises consisting in the whole body movements do not bring desirable effects in certain cases. The new methods of assessment of rehabilitation progress were presented. Those methods are based on receding of subjective symptoms during normal daily activities.

[Chemodectoma: tympanic tumor].

Glomus tympanicum tumors are the most common benign tumors of middle ear. Initially the leading symptoms are hearing loss and tinnitus. Other complications such as facial nerve paresis reflect deeper structures involvement. Sometimes the disease is masked by chronic pyogenic otitis media. It delays the diagnosis what we observed in one of three cases of chemodectoma presented. We present 3 cases of glomus tumor tympanicus that occurred in three women aged 60-68 years by the time of diagnosis. Localisation, size of the tumor and relation to other structures of the ear was made on the basis of computer tomography. The patients were operated (atticoantrotomy). In one of the cases there was recidivation of the disease two years after operation, we have made reoperation with hearing improvement. All the three patients were cured in outpatient before the correct diagnosis for a few years, they all presented typical symptoms together with typical changes in tympanic membrane. It is important to stress, that chronic pyogenic otitis media which first occurred as the patient was over fifty should arouse suspicion of neoplastic disease.

[A rare case of metastatic meningitis with unknown primary focus and atypical symptoms].

We have presented the diagnostic difficulties in the case of woman aged 59 who was admitted to the clinic with the suspicion of neurinoma of acoustic nerve. The patient was admitted to hospital with peripheral facial nerve paresis on the left side together with sudden surdity and peripheral vestibular impairment. Surdity of the other side occurred after two months. In terminal phase of the disease there was aseptic meningitis. Posthumous diagnosis was made on the basis of neuropathological examination of the brain. It was carcinomatous meningitis. But there was no primary focus found during autopsy. It is important to stress that CT and MRI was completely useless in this case. However pathological brain stem response together with lack of stapedial muscle reflex were much ahead of surdity and other central symptoms. We found only one case of carcinomatous meningitis with unknown primary focus in the literature. The course of the disease is very insidious and in every suspicious cases one should be aware of cancer of unknown primary site.

[Branchiogenic cysts registered at the Otolaryngology Clinic of Medical University in Wrocław in years 1989-1998].

Lateral branchiogenic cysts are relatively rare among neck tumours. However they belong to the most frequent developmental malformation in this area. Their etiology and pathogenesis is not fully explained yet. Over the period of ten years there were 76 patients hospitalized in our clinic with the diagnosis of the lateral branchiogenic cyst. Its prevalence was similar in both sexes and ranged from 3 months to 62 years of age. More than half of the patients were children. In 2 cases, a rare primary cancer rising from a branchiogenic cyst was diagnosed. Positive family history was observed in two children. Surgery was performed in 59 patients. Unsatisfactory results of the surgery were noted in 6 cases and 4 of them were reoperated because of the recurrence. In the case of brachiogenic cysts a full oncologic diagnostics should be performed, as it is done with neck tumour management. The procedures, which enable us to estimate character and extent of a lesion and determine the proper surgical treatment, should include ultrasonography, fine-needle biopsy or CT.

[Assessment of some biochemical factors of nasal mucosa in workers occupationally exposed to inhaled chemicals].

The aim of the work was to assesses the selected biochemical markers in nasal lavages obtained from 101 workers employed at a paint and lacquer factory who were exposed to inhalation of toxic substances. The concentrations of total protein and glycoconjugates were measured. The relationship was found between the concentration of substances under study, the clinical symptoms, and length of exposure. The increased levels of total protein and glycoconjugates were observed in workers with shorter period of employment, whereas those employed for longer period of time showed lower concentrations of both markers. The concentrations of the markers were also correlated with the progress of clinical symptoms. Workers with short employment showed mainly congestional changes, but in workers with longer exposure, atrophical changes in mucous membrane were observed. The results confirmed the usefulness of these markers in the objective assessment of the nasal mucosa condition.

[Rehabilitation of benign paroxysmal positional vertigo in the experience of the Wrocław Clinics].

Mechanical disturbances in inner ear in cupulo-utricular complex are the cause of Benign Paroxysmal Positional Vertigo (BPPV). Pharmacotherapy is ineffective in such cases. The results of rehabilitation with the use of Semont of Epley manoeuvres in 46 patients were presented. The regression of symptoms in 24 cases treated with the use of Semont manoeuvre was achieved in 62% and in 22 cases treated with the use of Epley manoeuvre in 73%. Theoretical assumptions of effectiveness of treatment applied were discussed on the basis of cupulolithiasis and canalolithiasis theories.

Poststeroid balance disorder--a case report in a body builder.

The authors describe a case of poststeroid balance disorder in a 20-year-old athlete. Previous information of such a doping pathology among sportsmen taking anabolics was not found. That anabolic steroids had a harm to central activities and could be suspected especially on the basis of reported psychiatric sequels and cerebrovascular disorders. The case described is of a patient who had been given metandienone, oxymetholone, and nandrolone phenyloproprionate in two courses. Vertigo appeared twice just after introducing doping and persisted in spite of a 1.5 year break in taking anabolics. In the electronystagmography a positional nystagmus was detected, the eye-tracking test was distempered, and abnormal responses in the caloric tests were obtained. In the computed dynamic posturography the number and length of body sway were increased and, consequently, the field of the outspread area was enlarged. The moment of appearance and long-lasting vertigo as well as the results of laboratory examinations indicate a poststeroid permanent disorder of the central part of the equilibrium organ. Such a diagnosis seems to be most probable here.

[Vestibulo-visual interaction in peripheral lesion of vestibular organ].

Studies were carried out on 32 persons between 38 and 54 years of age (average 45) with unilateral peripheral lesion function of the vestibular organ (among them 8 persons with complete lack of excitability) and 10 healthy persons between 23 and 42 years of age (average 32). All of the patients were examinated for vestibulo-visual interaction. With the help of electronystagmography, the eye movement was registered after visual stimulation, vestibular stimulation and simultaneous vestibulo-visual stimulation, with impulses evoking nystagmus of direction compatible and incompatible. Movement of black stripes on the white optokinetic screen with the velocity of 15 degrees/s, to the left and to the right, was visual stimulus. Vestibular organ was activated by cold water (30 degrees C), according to the Fitzgerald Hallpike's procedure. Nystagmus reaction was evaluated in the highest intensification on the basis of the mean velocity of the slow faze, amount of nystagmus deflexion, sum of amplitudes, as well as gain. We also took into account compatibility or incompatibility of the nystagmus directions which was induced by the simultaneous of the vestibulo-visual stimulation. It has been stated that the vestibulo-visual interaction in the unilateral peripheral lesion of vestibular organ does not differ in comparison with healthy persons. Besides, simultaneous vestibulo-visual stimulation induced by the impulses incompatible in their direction causes the decrease of the parameters value of the nystagmus in healthy persons and in persons with peripheral lesion of labyrinth. In the case of one-sided fall-out function of the vestibular organ an increase was observed of value gain of optokinetic nystagmus directed at the damaged side.

[The content of some trace elements in tissue of laryngeal squamous cell carcinoma].

The examination of the content of arsenic, nickel, copper, selenium, zinc, iron, cadmium, lead, cobalt, antimony and tin in the tissue of laryngeal squamous cell carcinoma was carried out. Material was taken from tumour of the larynx of 22 patients during laryngectomy. The control group was made up by healthy tissue of the larynx taken from 14 patients during diagnostic examinations. Trace elements were determined by means of BAIRD plasma spectrometer. Higher values of the concentration of arsenic, nickel, copper, cadmium, lead and cobalt were found in the tissue with carcinoma of the larynx as compared with the control group. The concentration of selenium, zinc, and iron in the carcinoma tissue was lower than in the healthy tissue. The concentration of antimony and tin was similar to that of the control group.

Content of trace elements in serum of patients with carcinoma of the larynx.

An examination of the content of arsenic, nickel, copper, selenium, zinc, and iron in the serum of 78 patients with carcinoma of the larynx was carried out. The patients were divided into 4 groups: I - patients before treatment, II - patients after surgical treatment, III - patients after radiotherapy, IV - patients after combined treatment (surgery treatment + radiotherapy). The control group was formed of 17 patients operated for deviation of the nasal septum. Higher concentrations of arsenic, nickel and copper were found in the serum of the patients with carcinoma of the larynx before treatment (group I) as compared with the control group, whereas the concentrations of selenium, zinc and iron were lower. In the groups of patients after treatment, the highest concentrations of iron and zinc were found after surgical treatment. The level of selenium in all groups of patients was considerably lower than in the control group.

[Pediatric neoplasms: laryngological manifestations].

Ten children with neoplasms of the head and neck were treated in the Clinic of Otolaryngology of Medical University in Wrocław. In 4 children non-Hodgkin lymphoma-type B (NHL-B) primarily situated in tonsils or adenoids were diagnosed, 3 patients suffered from embryonal rhabdomyosarcoma (RMS)--2 in the nasal cavity and the paranasal sinuses and 1 in the middle ear. One boy presented histiocytosis (LCH) in the orbit. In 1 case Hodgkin disease (HD) in the preauricular lympho nodes was found and in 1 child neuroblastoma of retromandibular region was detected. Our analysis revealed unsufficient oncological awareness of the physician who had examined the children as the first one. The neoplasms were detected in advanced stage. The onset of the treatment was additionally delayed because of the long period of expecting for the histological diagnosis.

[Histological and histochemical investigation of pathological laryngeal mucosa with papillomatosis in children and adults].

Papillomas of the larynx are the subject of numerous studies. They occur in two forms (multiple and singular). The authors presented the results of histological and histochemical investigations of larynx papillomas in 9 adults and 16 children. The studies comprised patients treated in the Clinic of Otolaryngology in Wrocław. Surgically removed lesions constituted the material for estimation. Peculiar attention was paid to the degree of differentiation of tumours under the microscope. The interdependence between intensification of reaction and degree of epithelhyperplasia and strict connection of intensification of reaction with quantity of dysplastic changes of epithelium were indicated by estimation of enzymatic reactions. Histological studies disclosed marked morphological differences between papillomas in children and adults. The correlation of reactions to lactic dehydrogenase and NADH2-tetrazole reductase can be treated as an expression of hyperplastic changes in the epithelium. What is more, the reaction to lactic dehydrogenase may be regarded as a metabolic index of malignancy.

[The evaluation of the balance organ in workers occupationally exposed to organic solvents and tinctorial dusts].

The aim of the study was to evaluate the balance organ in persons occupationally exposed to organic solvent vapours. The study was performed in a group of 35 workers employed for eight years on average in two departments of the Polifarb S.A. factory of patients and lacquers, Wrocław. The control group consisted of 53 healthy persons. Static and dynamic posturography was used to assess the condition of the balance organ. In the persons exposed static posturography tests revealed statistically significant increase in the field of spread area and extent of sways, and dynamic posturography tests indicated an increased radius. It was shown that posturography ensure an objective assessment of balance disorders and can be applied in the screening of persons exposed to toxic substances. It is also useful in recording functional condition of the balance organ.

[Vestibular evoked potentials in people].

In the article had been presented the structure and functioning of a prototype system for stimulation and registration vestibular evoked potentials, and the first recording of evoked vestibular potentials (VsEPs) in human beings. This system consist of a original stimulator accelerated for the stimulation of vestibular organ, modul registratory VsEPs as well as string elements and synchronizing stimulation with recording. IMB PC 486 is quickly process of investigation with help of standard interface and a original computer programme. Vestibular organ had been evoked by 200 to 500 cyclicly repealed angular decelerations of 4000 degrees/s2. During investigation white noise was used for masking to avoid the evoking of auditory potentials. Seven of the examined healthy persons (including one deaf person whose vestibular organ was not damaged) had registered a response consisting of several waves with vertex positive peaks. The first two waves P1 and P2 with the mean value 2.02 ms and 5.6 ms are most often during in the 10 ms. The registered deaf persons response does not differ from the record of healthy persons.

[Congenital nystagmus with sensory disorder: reaction to the caloric and optokinetic stimulation].

The purpose of this study was to estimate the response on vestibular caloric and optokinetic stimulation in patients with congenital nystagmus and serious congenital anomalies of visual system. 58 patients, aged 11-20 (21 female, 37 male) underwent this stimulation with ENG registration. The patients had visual acuity from 0.04 to 0.4, caused by visual system diseases e.g. congenital cataract, optic atrophy, hypoplasia maculae, high refractive error, albinism ect. The correct response was observed with 15.5% of the patients on vestibular caloric stimulation. There was no statistically significant relationship between visual acuity or visual system disease and the correct response. 28% of the patients responded correctly on optokinetic stimulation. There was statistically significant relationship between visual system anomaly and correct OKN: 80% of this reaction was in the group of optic atrophy, 54% in the group of high refractive error. Statistically significant relationship was no observed between visual acuiy and correct OKN. High level of the incorrect response on the caloric and optokinetic stimulation in the persons with congenital nystagmus and congenital disorder of visual system limits using of this tests for diagnostic purpose.

[Influence of vapours of paint and toxic dusts on mucous membranes of the upper airways in paint and varnish factory workers].

Macroscopic, cytologic and bacteriologic conditions of mucous membranes of the upper airways in workers (n = 146) of the Polifarb Factory, Wrocław, exposed to dusts and solvent vapours used in the paint and varnish production was estimated. In 89% of the workers, pathologic changes in throat mucous membranes were observed. Three types of macroscopic changes were distinguished. In workers with the shortest period of employment, laryngeal oedema congestion alteration was diagnosed, and atrophic changes with medium intensity were observed in workers employed for a long period. It was found that cytologic changes in the nose mucous membrane depended on the duration of exposure. Inflammation cytograms appeared during the first period of exposure to the substances discussed. The longer period of exposure, the more clear features of metaplasia squamous epithelium. The composition of the nose and throat bacterial flora changed according to the length of employment. An increased growth of G(-) genera Enterobacter, Klebsiella, Proteus, Escherichia and Candida fungi was found in workers with long period of employment.

[Computer system of the electronystagmographic examination. Part III. Comparative results obtained by computer and traditional technology in the examination of the vestibular organ].

The study presents a comparison of the research into results of vestibular organ stimulated with caloric tests which had been simultaneously registered with the help of a computer system of electronystagmographic examination, as well as the traditional electronystagmographic technic. In the case of 32 healthy persons there had been counted by hand average angular velocity of the slow phase caloric nystagmus average level of reduced excitability of labyrinth and direction predominance. It had been defined that those values are comparable to the ones given by the computer. That points to the right chose of the space of time in the climax of nystagmus reaction and a good identification of the phase both slow and fast by the computer system.
