    ABSTRACT: In recent years, it has become clear that HPV affects the development of head and neck cancer, particularly oropharyngeal squamous cell carcinoma (OPSCC). HPV-related OPSCCs are reported to be frequently observed among patients with a relatively younger age and those without smoking habits, and also to show a relatively better prognosis compared with OPSCC patients without HPV infection. In the United States, the incidence of HPV-related OPSCC has been increasing in association with the diversification of sexual activity among young individuals. Similarly, the incidence of HPV-related carcinomas has been increasing in Japan. For instance, uterine cervical cancers have been increasing among younger females, and the incidence of OPSCC has also been gradually increasing in spite of a decreasing trend in smoking habits and alcohol consumption. However, there have been only a few Japanese studies that have examined the incidence and prognostic significance of HPV infection in terms of its impact on the outcomes of OPSCC. Therefore, further analyses are needed to establish an appropriate treatment strategy for Japanese OPSCC patients. The aim of this study was to elucidate the frequency and clinical implications of the HPV infection status in Japanese OPSCC, using both a sequencing analysis and IHC.

    ABSTRACT: Conclusions: Reconstruction of the ossicular chain differentially affects the motion of the tympanic membrane (TM) and the stapes. Objectives: To determine the effect of different ossicular replacement procedures on the sound-induced motion of the TM and stapes. Methods: A combination of digital stroboscopic holography and laser Doppler vibrometry was used to determine the sound-induced motion of the TM and stapes in cadaveric temporal bones in which the ossicular chain was reconstructed using 12 varied standard techniques. The variations included the use of total or partial ossicular prosthesis, size of cartilage interposed between the TM and the prosthesis, and the length or fit of the prosthesis between the TM and stapes. The measurements were carried out in repeated measures format, so that each manipulation was performed in each temporal bone. Results: The volume displacement of the TM was in general reduced by reconstruction, with the largest reductions occurring with high-frequency stimulation in the reconstructions with a ‘large’ cartilage oval interposed between the TM and the prosthesis. Larger stapes motions in response to low-frequency sound were observed with either ‘loose’ or ‘best’ fit TORP with a ‘small’ cartilage plate between the TM and the prosthesis.

    ABSTRACT: Conclusion: Sensorineural hearing loss (SNHL) is a neurological situation and celiac disease (CD) may be seen coincidentally. Children with clinical signs of hearing deficiency of unknown etiology should be assessed for CD. Objective: CD is a chronic inflammatory gluten-dependent intestinal disease and has extraintestinal findings. The aim of this study was to determine the incidence of CD and SNHL in our pediatric patients.Methods: A total of 25 pediatric patients (50 ears) with biopsy-proven CD were diagnosed in the pediatric gastroenterology department; 25 healthy control subjects (50 ears) were also included in the study. All subjects underwent pure tone audiometry at frequencies of 250–8000 Hz and tympanometry. Results: In the patients and controls, normal peak compliance, gradient, peak pressure, ear canal volume, and acoustic reflexes were obtained by tympanometry. There was no air–bone gap in any of the participants. There was a statistically significant difference between the audiometric results in the CD and control groups (right ear and left ear) (p < 0.05).

    ABSTRACT: Angiogenesis is a hallmark of cancer, fundamental to its growth. The 'angiogenic switch' occurs when pro-angiogenic factors are not balanced by anti-angiogenic factors. A correlation between angiogenic properties and oncological prognosis (for laryngeal squamous cell carcinoma (LSCC) too) was first hypothesized in the 1990s. An exhaustive literature review was performed to investigate available data on angiogenesis markers and their biological role and therapeutic potential in LSCC. The prognostic significance of microvascular density in LSCC was investigated with endothelial targets, e.g. CD105, CD34, and CD31. Epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), VEGF receptor 2, angiogenin, hypoxia-inducible factor 1, and other biological markers were also studied. Only anti-EGFR therapy has been approved by the USFood and Drug Administration (FDA) for head and neck carcinoma in recent years, while several agents interfering with VEGF and its receptors are being studied. Experimental findings indicate that anti-CD105 monoclonal antibodies efficiently inhibit tumor angiogenesis. There are two main ways to approach the vascular profile of solid malignancies: by inhibiting new vessel formation (anti-angiogenic therapy) or selectively damaging neoplastic vessels (vascular targeting therapy). In advanced LSCC, both these strategies seem promising and warrant further preclinical and clinical investigation.

    ABSTRACT: Patients with Bell's palsy were investigated with regard to the cellular immune response during the acute and convalescent stages with the purpose of acquiring information concerning the etiology of the condition. In order to ascertain whether there was activation of the immune system, the proportion of activated T cells in the peripheral blood of 14 patients with Bell's palsy was analysed using monoclonal antibodies. A transient increase of these cells occurred in the acute stage, with a return to normal in the convalescent stage. The Leu-7+ cells which play a role in the natural cellular defence against viral infections, were also studied by using monoclonal antibodies in 25 patients. A significant change in the percentage of Leu-7+ cells was not found when the samples from the entire group were analysed. However, 10 patients who were investigated between September and October 1984, when the incidence of Bell's palsy was comparatively high, showed significantly lower percentages of Leu-7+ cells in the acute stage compared with the convalescent stage. The increase in the activated T cells in the acute phase of the palsy suggests a cell-mediated, immuno-regulatory abnormality with primary or secondary immune activation. Similar cellular immune alterations are found also in multiple sclerosis. Further, the differences in the proportions of Leu-7+ cells which occurred in these 10 patients may denote a contribution of various etiological factors to the disease.

    ABSTRACT: During a one-year period, 82 consecutive patients seeking medical attention for facial palsy primarily of unknown etiology were examined for underlying Ixodes ricinus-borne borreliosis. Evidence of the infection was found in 16 (20%) of the patients, most of whom had cerebrospinal fluid findings indicating meningeal involvement. Among 9 children included in the study, borreliosis was found in 6 cases. Bilateral facial palsy occurred in 3 of the borrelia-infected patients, as compared with none of the patients without borreliosis. It is suggested that, in areas where the tick vector is present, borreliosis should be regularly sought in patients with facial palsy of otherwise unknown etiology. As regards the serological diagnosis, it is emphasized that normal borrelia antibody titres in serum and cerebrospinal fluid at the time of the first consultation do not exclude the infection. A careful serological follow-up of patients with facial palsy is therefore recommended in order not to miss an underlying borreliosis which, if allowed to go untreated, implies a risk of other organ involvement and a protracted course.

    ABSTRACT: Rats were exposed to toluene (1000 ppm, 16 h/d, 5 d/w, 2 w), or noise (100 dB Leq, 10 h/d, 7 d/w, 4 w) or toluene followed by noise. Auditory function was tested by brainstem audiometry using a 1/3 octave filtered sine wave stimulus at the frequencies 1.6, 3.15, 6.3, 12.5 and 20.0 kHz. A high-frequency auditory impairment was observed after exposure to toluene alone and noise alone. A slight recovery was recorded 1 and 6 months after the toluene exposure. Toluene followed by noise resulted in a higher threshold at all frequencies. A slight recovery was recorded 6 months post-exposure. The threshold shift exceeded the summated loss caused by toluene alone and by noise alone, particularly at 3.15 and 6.3 kHz. The latencies varied only slightly. The results indicate that the major cause of the auditory impairment was cochlear damage and that only minor injury was caused to the auditory pathways.

    ABSTRACT: Abstract Conclusions: Selecting patients that are candidates for surgical treatment is important in the work-up of patients with tracheal cancer. Toward this goal, centralization of care concerning tracheal tumors is advised. Centralization may increase long-term survival and decrease operative morbidity and mortality even further. Objective: Primary tracheal tumors pose a diagnostic and therapeutic challenge for the physician when confronted with this mostly malignant tumor. Diagnosis is often delayed for months or years due to its aspecific and asthma-mimicking symptoms. Knowledge from retrospective series is limited and few clinicians have gained experience with this tumor. The available literature on the diagnosis and management of this group of tumors is reviewed to summarize the available knowledge about these uncommon tumors. New diagnostic, staging, and treatment guidelines are proposed. Methods: PubMed was searched for English publications from 1960. The available literature was reviewed and summarized. Results: Surgical resection and primary reconstruction is the best curative treatment modality available at present. In centers of experience, more than half of all patients with tracheal cancer may be candidates for surgical resection, although in population-based studies this treatment is applied in only 10-25% of patients.

    ABSTRACT: The medial wall of the bony portion of the Eustachian tube was examined, by anatomical and histological methods, in 150 temporal bones of adults. This wall consists of two parts: posterolateral (labyrinthine) and anteromedial (carotid), whose shapes, sizes and relations depend upon the position of the a. carotis interna. If it is located nearer the tympanic opening of the tube, the labyrinthine part of the wall is smaller and has a triangular shape. The further the artery is removed from the tympanic opening of the tube, the greater and more rectangular the shape of this part of the wall. The part of the medial wall which corresponds to the a. carotis interna can differ in each case and in 69% of the cases this part extended more or less into the lumen of the tube. The average thickness of this part of the wall is 1.5 mm (minimum is wafer-thin and maximum is 3 mm). In 2% of the cases the bony wall above the a. carotis interna was missing, so that the artery projected into the protympanum. Through a bone defect, aneurysm of the artery can develop. In one case, during an operation, it was established that the protrusion of the a. carotis interna into the tympanic cavity was due to a defect in the medial wall of the Eustachian tube.

    ABSTRACT: Starting from age 2 up to 7 years, 79 otherwise healthy children underwent nine tympanometric tests. At the age of 7, mastoid X-rays were obtained and the air cell areas measured by planimetry. The mean area was 8.4 cm2, with a left-right mean difference of 1.57 cm2. The children could be divided into three groups: (1) the ears with the smallest cell system associated with abnormal tympanograms (i.e. 'agreement'); (2) the ears with the largest cell system associated with abnormal tympanograms (i.e. 'disagreement'); (3) children with symmetrical cell systems and tympanograms. Significant majority of children showed 'agreement'. The results indicate that the size of the mastoid air cell system is determined by the degree of pathological involvement of the middle ear during childhood.

    ABSTRACT: Cochlear endolymph, scala tympani perilymph, and scala vestibuli perilymph were collected from fetal, neonatal, and mature guinea pigs. The concentrations of Na and K in these fluids were then assessed using a microflame photometer. The electrolyte composition in the endolymph was already characterized by a high concentration of K and a low concentration of Na by the 49th day of gestation.

    ABSTRACT: The effect of histamine was studied on canine nasal blood vessels with an in vitro muscle tension measuring technique. Observations suggest that histamine has at least four different effects: 1) inhibits the contraction induced by nerve terminal stimulation, 2) relaxes the smooth muscle under sustained contraction, 3) contracts the smooth muscle, 4) enhances (nor)epinephrine-induced contraction. Both H1 and H2 histamine receptors were identified in the mucosal blood vessels of the canine nasal septum. H1 receptors were present at the surface of vascular smooth muscle and mediated the contractile response (3) due to opening calcium influx channels. H2 receptors existed at both sympathetic nerve terminals and the muscle cell membrane. Stimulation of either H2 receptor caused muscle relaxation. The presynaptic H2 receptors mediated vasodilation through the inhibition of norepinephrine release from the nerve endings. Postsynaptic H2 receptors caused direct muscle relaxation possibly through an increase in cyclic AMP. Both H1 and H2 antagonists worked well, whereas agonists did not properly produce theoretically expected results in these specimens.

    ABSTRACT: A case of tracheal dystonia is submitted. In a 44-year-old woman with increasing dyspnoea of predominantly expiratory type, bronchoscopy revealed abnormal yielding and bulging of the right side of the membranous tracheal wall. The bulging was situated in the upper 8 cm of the trachea and varied in extent with the intratracheal pressure. At operation the membranous wall was found to be extremely yielding, in spite of normal width. Adjacent to the abnormal part of the membranous wall there was an enlarged lymph node which on microscopic examination exhibited changes indicating sarcoidosis. The membranous wall was supported by a strip of Teflon, and since the operation the expiratory dyspnoea has improved. The present case is compared with reported cases of tracheobronchial dystonia. It is concluded that the yielding of the membranous wall may have been due to long-lasting pressure by the lymph node, destroying the submucous elastic fibres.

    ABSTRACT: Twenty-four caloric vestibular tests were conducted in 20 test subjects during parabolic flight, in which weightless periods of about 10 seconds were elicited. The caloric nystagmus disappeared completely in all experiments in weightlessness, whereas in the higher G-periods the speed of the nystagmus increased. With regard to the modes of response during the periods with increased G-values prior to and following the weightlessness, four different types could be distinguished. In mode I the speed of the slow nystagmus phase increased in the higher G-periods, the nystagmus showed a prolonged duration, while in weightlessness it faded out completely. A reversed nystagmus appeared when the primary caloric nystagmus had disappeared. In modes II, III and IV the direction of the nystagmus reversed during weightlessness. In modes II and III this reversed nystagmus appeared even when the primary caloric nystagmus had disappeared. In mode III the nystagmus resembled the type of mode II, with the difference that it faded away much earlier than could be expected. In mode IV the primary nystagmus lasted rather briefly, while the reversed nystagmus during weightlessness was also much shorter. The experiments produced two remarkable facts: the appearance of a nystagmus reversal, a 'secondary nystagmus', in all experiments in weightlessness, and furthermore great differences in findings between the individuals as well as between experiments in the same person. The only explanation for the inconsistency in the findings is the assumption that effects on other canals, otoliths and vestibular nuclei are continuously changing and therefore interfere with the only endproduct measured, the horizontal nystagmus.(ABSTRACT TRUNCATED AT 250 WORDS)
