Malignant neoplasms of the oral cavity and oropharynx in Poland make about 4% of all the malignant tumors in men and 1% in women. 90% of the histologic diagnoses is the squamous cell carcinoma. The ...most frequent sites of these neoplasms are: lower and lateral surface of the tongue, the bottom of the oral cavity, lingual surface of the labial gingiva, retromandibular triangle, tonsils and the root of the tongue. About 85% of all oral cavity and oropharynx tumors are detected after they reached 2 centimetre in diameter. 60% of these tumors are recognized in the level III or IV of the clinical grading. The aim of the study was to estimate the frequency of the oral cavity and oropharynx malignant neoplasms, their clinical grading, evaluation of histologic results and a kind of treatment. A retrospective analysis of 201 patients treated at The II ENT Department Silesian Medical Academy in Zabrze because of the oral cavity and oropharynx malignant neoplasms.
In our group were 45 women and 156 men. The majority of the patients were clinically advanced of the disease. The most frequent site of the tumor was the tongue and tonsils. Histopathological study showed that the most frequent diagnosis was the squamous cell carcinoma (92.5%). In the greater part of the patients the combined treatment (surgery and radiotherapy) was applied (62.7%). The most important activity for the survival time elongation and decrease of the crippledom after surgery is the early detection of the disease.
74 miners, aged 19-35, exposed to industrial noise were examined by means of otoacoustic emission (TEOAE). The group was divided into 3 subgroups depending on the time of noise exposure. Significant ...weakening of otoacoustic emission in all subgroups was observed, even in subgroup with the shortest time of noise exposition and normal audiogram. The results were confirmed by others authors. Otoacoustic emission (TEOAE) could be very useful in early detection of hearing impairment cause by noise. 74 miners, aged 19-35, exposed to industrial noise were examined by means of otoacoustic emission (TEOAE).

In this study there is presented a case of unilateral, idiopathic, severe sensorineural hearing loss in a child. The inner ear pathology has been confirmed by tonal and impedance audiometry, and ...brainstem evoked response audiometry. Simultaneously in the same ear normal otoacoustic emission (SOAE, TEOAE, DPOAE) has been recorded. MRI did not reveal any pathology in internal ear canal and cerebellopontine angle. The presented case suggests that there is a possibility of existence of the normal outer hair cell function with simultaneous inner ear cell disorder or first neuron pathology. Similar cases of idiopathic sensorineural hearing losses with preserved otoacoustic emissions in children were described by Katona (1993), Welz-Mueller (1993) and Konradsson (1996).
Distortion product otoacoustic emissions (DPOAE) are generally accepted as a good tool for investigating the micromechanics of the cochlea. The 2f1-f2 DPOAE latencies provide significant data ...regarding travelling waves. In this study the 2f1-f2 DPOAE latencies were measured using a phase-gradient method, with a swept-f2 procedure, for three groups: Group I comprised 60 healthy young people, aged 17-32 years; Group II comprised elderly patients, aged 56-72 years, with presbyacusis; and Group III consisted of 74 miners, aged 19-35 years, who had been exposed to noise for 2-15 years. Measurements were performed for frequencies between 1.0 and 6.0 kHz. In all groups the latencies were fitted using a non-linear regression model. The aim of the study was to compare the latency and amplitude of 2f1-f2 DPOAE in different inner ear pathologies. The highest DPOAE amplitudes were recorded in Group I and in miners with 2-4 years noise exposure (Group IIIa), and the latencies showed a similar pattern. The lowest DPOAE amplitudes were recorded in the elderly and in miners with 8-15 years noise exposure (Group IIIc), but in contrast the longest latencies were measured in miners and the shortest in the elderly. The latency analysis significantly reinforces opinions on the micromechanics of the cochlea, mostly in terms of the cochlear functioning as a filter and amplifier and with regard to the elasticity of the basilar membrane.
In the group of 544 patients with squamous cell cancer of supraglottic and glottic larynx the effect of primary tumour localisation on the response to radiotherapy was analysed. There were 156 ...patients with glottic cancer T1-T3 N0-N2 and 388 patients with supraglottic cancer with T1-T4 N0-N3. The most common site of extralaryngeal involvement was piriform fossa. All patients were treated with the use of external megavoltage beam. The total dose was in range 59-80 Gy. The 5-year actuarial disease-free survival was 36% for supraglottic cancer and 63% for glottic cancer. Primary tumour localisation in glottis correlates with more favourable prognosis than that in supraglottic. Extension from supraglottis to glottis worsened the prognosis more than that in opposite direction. For extralaryngeal involvement the most favourable prognosis was the infiltration of lingual-epiglottidean fossa and the worst one for the base of tongue involvement.
A group of 74 miners, aged 19-35 years, exposed to industrial noise at average level of 82-88 dBA for 1.5 to 15 years were examined by means of otoacoustic emission (TEOAE). The group was divided ...into three subgroups, depending on the duration of noise exposure. The results obtained in miners were compared to the results of the control group nonexposed to noise at the workplace. Otoacoustic emission was weaker in subjects exposed to noise. Significant differences in responses were found in subgroups II and III as compared to controls. The results were compared to the data reported by other authors. The role of otoacoustic emission in providing information about dynamics changes in hearing impairment, depending on the duration of noise exposure, in subjects exposed to industrial noise, was emphasised.
Latency time and rise time of the stapedius muscle reflex were examined in 32 healthy young people. No significant difference between woman and man were reflected. Obtained result were compared with ...the previous data of the various authors. Necessity of the own norm estimation of this parameters were emphasized.
The hearing system in newborns from the Upper Silesia. Assessment of TEOAE depending on selected parameters of delivery disorders Transient evoked otoacoustic emission (TEOAE) is an accepted test for ...screening of the cochlea function in newborns. In this study 300 newborns was tested using TEOAE, as well as analysing such parameters as birth weight, Apgar scale, bilirubinaemia. The study indicated the tendency of TEOAE to decrease in newborns with low birth weight and low Apgar scores. Hyperbilirubinaemia seems to have an influence on cochlea function monitored by TEOAE, especially if there were simultaneously low Apgar scores. A similar tendency, although slightly stronger, was observed in the preterm newborn group. TEOAE seems to be a good method of recording the negative influence on the cochlea activity such factors as low birth weight and asphyxia. Hyperbilirubinaemia with asphyxia acts upon the cochlea similarly. All these tendencies were observed more strongly in the preterm newborn group. It is concluded that TEOAE analysis demonstrated its utility as a screening test assessing the hearing state in newborns, additionally the associations of cochlea activity was found with a few parameters of delivery disorders.
We described natural history of Pseudomonas aeruginosa septicemia in 9 year old boy, who was treated for acute lymphoblastic leukemia (ALL). After 14 day treatment of ALL the following signs and ...symptoms occurred: fever, earache with otorhoea, deafness, bilateral peripheral paralysis of n. VII, erythema, pneumonia, paralytic ileus. After 4 weeks of antimicrobial and supportive therapy, in the 10th week of chemotherapy, he achieved haematological remission. During continuation therapy, two-stage bilateral myringoplasty was performed. At present the maintenance therapy is continued, and in the future hearing aid and cochlear implant, will be applied.
