Abstract
Expression profiles of CXC- and CC-chemokines in various forms of tonsillar disease were studied to evaluate whether certain chemokines play a predominant role in a specific subset of tonsillar disease. Total RNA was isolated from 89 biopsies (21 hyperplastic palatine tonsils, 25 adenoids, 16 chronic inflammatory palatine tonsils and 27 chronic inflammatory palatine tonsils with histological prove of acute inflammation), reverse transcribed and subjected to PCR amplifying IL-8, Gro-alpha, eotaxin-1, eotaxin-2, MCP-3, MCP-4 and RANTES. 2% agarose gel electrophoresis revealed a predominance of IL-8 in the chronic inflammatory palatine tonsil group compared to tonsillar hyperplasia. Furthermore, eotaxin-2 was strongly overexpressed in adenoid samples compared to chronic inflammatory specimens. Our data suggest that the majority of diseases related to adenoid formation are mediated via an eotaxin-2 expression, whereas chronic inflammatory tonsillitis is associated with IL-8 upregulation. These data imply that adenoids are related to a Th-2, and chronic inflammatory tonsillitis to a Th-1 based immune response.

Abstract
BACKGROUND Prognosis of patients with advanced/recurrent cancer of paranasal sinuses and orbit with infiltration of the skull base is very bad. Radical surgery does not improve prognosis. A disadvantage of the radical surgery is the functional loss and the residual cosmetic defect. We present the results of a function-preserving surgery in combination with interstitial, image adapted brachytherapy (IABT) for the treatment of these cancers. METHODS AND PATIENTS Ten patients with paranasal sinus cancer and 16 patients with sarcomas (n=26) were retrospectively analysed. After a maximum tumor resection (mostly R1-R2 resections), 2-12 flexible afterloading plastic tubes were implanted. The postoperative IABT total dose was 10-25 Gy in 2.5 Gy fractions twice daily fractions for 5 days. RESULTS In all cases the eye was obtained without functional damage. The IABT was well tolerated. The visual and cosmetic results were satisfactory. Postoperative complications occurred in 7 out of 26 cases without a serious long-term adverse event. Significant radiation-induced complications were found in patients with orbital or skull base involvement. The three years overall survival was 60% for rhabdomyosarcoma, and 33% for the paranasal sinus cancers. CONCLUSIONS These results show that a combined treatment of function-preserving surgery and a IABT is a feasible, successful and well-tolerated option for curative, salvage and palliative therapy for selected patients with advanced or recurrent carcinoma of the paranasal sinuses and orbit.

Abstract
BACKGROUND Nasal polyposis is mostly associated with eosinophilia of mucosal tissue. This points to the implication of CC chemokines in nasal eosinophilia. Recently the CC chemokine eotaxin-2 (CCL24) was identified. This study was initiated to localize the cellular source, analyze expression of mRNA, and quantify protein synthesis of CCL24. METHODS Specimens of nasal inferior turbinates from controls and polypous tissue from patients suffering from chronic polypous sinusitis were collected. Furthermore, fibroblasts and epithelial cells were cultured. CCL24 protein was analyzed by immunohistochemistry and ELISA, expression of mRNA by SQ-RT-PCR. RESULTS CCL24 was observed in endothelial and epithelial cells. Specimens from patients expressed significantly (>2fold) more CCL24 mRNA than controls. Fibroblasts and unstimulated cells did not express CCL24 mRNA. Upon stimulation with TNF-alpha, INF-gamma, IL-4, or costimulation with TNF-alpha and INF-gamma CCL24 mRNA was significantly enhanced (3.2-19.6%). In controls, fibroblast, and unstimulated cells CCL24 protein was below detection limit. Most polyps comprised significant amounts of CCL24 (mean 0.24 ng/mg). TNF-alpha, INF-gamma or IL-4 induced CCL24 protein (0.1-0.3 ng/ml) in epithelial cells. Costimulation with TNF-alpha and IL-4 (0.1-30 and 1-30 ng/ml, respectively) synergistically induced synthesis of CCL24 protein (0.18-0.31 ng/ml). CONCLUSION In nasal polyps endothelial and epithelial cells are obviously the main source of CCL24, which was shown for transcription (mRNA) and production (protein) levels and was associated with diseases. Results gave evidence of CLL24- directed migration of cells from inside (the bloodstream) to the epithelial side (mucosa) in eosinophilic inflammatory diseases, e.g. nasal polyposis.

Abstract
Infections of healthy skin or mucous membranes are rare despite constant exposure to microbial colonization. Nonspecific and specific defense mechanisms correspond in the nose: the mucociliary clearance provides very effective mechanical cleaning. If this protection is insufficient, the nasal epithelium comes into close contact with microorganisms. This triggers the recently discovered production of the body's own specific antimicrobial peptides (AP). It seems that it is difficult for microorganisms to form enzyme-induced resistance to AP. This makes AP highly interesting for the development of new antibiotics. The observation that antimicrobial activity can be induced has also led to the hypothesis that natural substances may possibly stimulate endogenous AP production. If this line of defense also fails, the inflammatory cells migrate from the blood into the tissue and, with their capacity for phagocytosis, the enzymatic attack on bacteria can cause a cellular inflammatory reaction in the nasal mucous membrane.

Abstract
We report the case of a 67 year old patient suffering from acute airway obstruction caused by hemorrhage localized to the tongue, mouth cavity and hypopharynx, with no evidence of bleeding in his history. The patient presented initially with a globus feeling of the neck, dysphagia and a sore throat. CT scan revealed a swelling of the lingual and sublingual areas and the pharyngeal wall. Next day, there was an immediate life-threatening event caused by progressive bleeding with airway obstruction and an inability to intubate requiring coniotomy. The etiology of the hemorrhage was confirmed by finding a depletion of factor VIII and the presence of auto-antibody directed against this factor. Based on this case report and a review of the literature, we discuss the diagnosis and treatment of acquired hemophilia.

Abstract
One hundred and forty-seven adult recipients of the Nucleus 24 cochlear implant system, from 13 different European countries, were tested using neural response telemetry to measure the electrically evoked compound action potential (ECAP), according to a standardised postoperative measurement procedure. Recordings were obtained in 96% of these subjects with this standardised procedure. The group results are presented in terms of peak amplitude and latency, slope of the amplitude growth function and ECAP threshold. The effects of aetiological factors and the duration of deafness on the ECAP were also studied. While large intersubject variability and intrasubject variability (across electrodes) were found, results fell within a consistent pattern and a normative range of peak amplitudes and latencies was established. The aetiological factors had little effect on the ECAP characteristics. However, age affected ECAP amplitude and slope of the amplitude growth function significantly; i.e., the amplitude is higher in the lowest age category (15-30 years). Principal component analysis of the ECAP thresholds shows that the thresholds across 5 electrodes can be described by two factors accounting for 92% of the total variance. The two factors represent the overall level of the threshold profiles ('shift') and their slopes across the electrode array ('tilt'). Correlation between these two factors and the same factors describing the T- and C-levels appeared to be moderate, in the range of 0.5-0.6.

Abstract
We report on two patients with ossifying fibroma of the anterior skull base with intracranial extension. A psammomatoid ossifying fibroma was removed from a 29 year old female patient, and in a 37 year old female patient a cemento ossifying fibroma was removed. The main clinical symptom in both cases was headache. Surgery took place after diagnosis and therapy in an interdisciplinary operation with ENT colleagues. The ossifying fibroma is a benign neoplasm mainly affecting the maxilla and mandible. Complete removal is better than a curettage of the tumor.

Abstract
The aim of the study was to assess the diagnostic value of the sentinel node method in patients suffering from squamous cell carcinoma of the upper aerodigestive tract. In 50 patients with oral, pharyngeal or laryngeal carcinomas staged N0 up to 50 MBq technetium-99m colloid were injected peritumorally. Sentinel nodes were localised using a gamma-probe in the setting of an elective neck dissection. Pathological findings of sentinel nodes and corresponding neck specimens were compared. In 46 patients sentinel nodes were detected. Of these 34 patients were free of metastatic disease in the sentinel nodes and in the neck specimens. In 12 patients clinically occult metastases were found in the sentinel nodes. Three metastases were detected only after additional sectioning of the sentinel nodes. In four patients, a sentinel lymph node could not be localised. Our results support the sentinel node concept in head and neck cancer and a definition of the sentinel nodes as the three nodes with the highest activity. Careful clinical staging of the neck and thorough pathological evaluation of the sentinel nodes are necessary to avoid false-negative results.

Abstract
Economies in National Health Systems forces ENT surgeons to review their indications for outpatient tonsillectomy. Therefore, it is important to preoperatively identify special risk groups who frequently have extensive posttonsillectomy bleeding with the need of a blood transfusion. Aim of this study was to estimate the incidence for posttonsillectomy bleeding related blood transfusion, to identify risk factors associated with the need for blood transfusion and to release guidelines for posttonsillectomy bleeding of high risk patients. A retrospective study was done on the medical history of 1720 patients who underwent tonsillectomy for chronic tonsillitis between 1982-1993 in the ENT Department at the University of Kiel. The average transfusion rate was 0.52%. End Stage Renal Disease and hypertension combined with a preoperatively decreased Hb and Hct were the risk factors identified leading to a transfusion. These patients should not get a tonsillectomy as an outpatient procedure. The Hb, Hct, PT, PTT, blood type and crossmatch should be drawn and assessed prior to tonsillectomy. We recommend immediate treatment of secondary hemorrhage in those high risk patients under general anesthesia to avoid severe complications.

Abstract
BACKGROUND Atypical symptom in patients with bilateral vestibular loss is head movement-induced oscillopsia. The paucity of precise complaints in many patients is surprising. Therefore, bilateral loss of vestibular function is often undiagnosed. PATIENTS We report on the long-term follow-up in 29 patients. They were monitored for 2-7 years (mean: 4.5 years). RESULTS Of the 29 patients 16 described oscillopsia. All symptomatic patients had acute bilateral vestibular loss.Patients described that their symptoms improved over a period of 1-2 years. Improvement was not age dependent. CONCLUSIONS Otoneurologists should be aware of the particular clinical symptoms in bilateral vestibular loss. Regarding clinical features, compensation of bilateral vestibular loss seems to be unlikely only based on central compensatory eye movement reflexes. More likely perceptual adaptations and restriction of head movement are responsible for subjective improvement.

Abstract
The palatine tonsils have an undoubted role in the immune defence system. After antigen contact an effective adaptive immune response by B- and T-cell lymphocytes will be released. In addition the palatine tonsils seem to exert influence to the defence by the innate immune system. Therefore, we studied the ability of palatine tonsils to express different alpha and beta defensins and to find out any distinctions in chronic inflamed tonsils. Total RNA of 49 specimens of hyperplastic tonsils and chronic tonsillitis with pathological provided evidence of Actinomyces israelii was isolated using TRIzol protocol, reverse transcribed and the HNP-1, HNP-4, HBD-1 and HBD-2 gene expression densitometric determined, standardised in relation to glycerinaldehyd-3-phosphatdehydrogenase gene expression, after a semiquantitative polymerase chain reaction was performed. mRNA of HNP-1, HNP-4, HBD-1 and HBD-2 was detected in tissue samples, but their amount differed within the two defensin families and tissue of origins. HBD-1 was detected in all 49 tissues of hyperplastic tonsils and chronic tonsillitis. Only in chronic inflamed tonsils the amount of HBD-2 mRNA expression was significant increased. In these specimens also mean relative expression rate of all defensins was observed to be manifestly increased. Palatine tonsils express mRNA for different alpha and beta defensins and this expression suggest a newly supposed function in immune defence: the participation in the innate, non-adaptive immune system. Thus, palatine tonsils have a potentially influence in the growth and control of the physiological mouth bacteria by their bactericidal activity.

Abstract
BACKGROUND To compare gene expression patterns between laryngeal squamous cell carcinoma (SCC) cells and their normal phenotypes to identify genes showing differential expression. MATERIALS AND METHODS Messenger RNA was isolated from both kinds of cells, reversely transcribed and subjected to differential display reverse transcription (DDRT)-PCR. Gene fragments showing difference in the expression were recovered, reamplified, cloned and sequenced, enabling homology search. Total RNA was isolated from laryngeal SCC cells and adjacent normal mucosa and subjected to Northern hybridization. RESULTS A 159 bp gene fragment was detected, revealing 96% homology with the human myosin-binding protein-C1 (MYBPC-1) gene. Compared to the benign phenotypes the expression of MYBPC-1 was particularly increased in SCC cells, confirmed by Northern hybridization. CONCLUSION The results presented in this work may help to extend the diagnostic panoply available for the evaluation of laryngeal tissue conspicuous for malignancy.

Abstract
Patients with recurrent or refractory head and neck squamous cell carcinoma received cisplatin/epinephrine injectable gel or placebo gel injected directly into the clinically dominant tumour. The double-blind phase III trial comprised of up to 6 weekly treatments over 8 weeks, 4 weekly evaluation visits, and then monthly follow-up; open-label dosing began as needed after three blinded treatments. Tumour response was defined as complete (100% regression) or partial (50-99% regression) sustained for > or =28 day, and patient benefit as attainment of palliative or preventive goals prospectively selected by investigators and patients. With cisplatin/epinephrine gel, 25% (14 out of 57) of tumours responded (16% complete regression, 9% partial regression), vs 3% (one out of 35, complete regression) with placebo (P=0.007). Patient benefit was positively associated with target tumour response in the blinded period among cisplatin/epinephrine gel recipients (P=0.024): 43% (six out of 14) of responders benefited, vs 12% (five out of 43) of non-responders. The most frequent adverse event was pain during injection and the next most frequent was local cytotoxic effects consistent with the gel's mode of action. Systemic adverse events typical of intravenous cisplatin were uncommon. Intratumoural therapy with cisplatin/epinephrine gel provided safe, well-tolerated, effective palliative treatment for patients with locally advanced head and neck squamous cell carcinoma, who lack other satisfactory treatment options.

Abstract
BACKGROUND The quality of life (QoL) of patients with malignant diseases decreases significantly. OBJECTIVE The evaluation of QoL is generally not part of the management of patients with head and neck cancer. The aim of this study was to develop an additional disease- and treatment-specific questionnaire to evaluate QoL in surgically treated head and neck cancer patients. PATIENTS AND METHODS The general QoL was evaluated with the QLQ-C30 questionnaire developed by the European Organisation of Research and Treatment of Cancer (EORTC). RESULTS The disease-specific QoL was evaluated using the EORTC H&N35 module. The new questionnaire "Kiel Head and Neck 17" (KQL H&N-17) is a disease- and treatment-specific addition especially in regard to side effects caused by surgical treatment. CONCLUSIONS A wide application of this whole concept is needed to obtain comparable results from studies suitable for evaluating QoL in patients receiving different treatments for their malignant diseases. Moreover, the effectiveness and quality of treatment could be controlled better, which would help to increase the QoL of these patients.

Abstract
The notion of quality of life (QL) was first introduced in the US in the 50-ies. This notion is much broader then health, it is a personal, subjective feeling of well-being that comes from actual, widely-meant life experiences. The QL is not a measurable value, however, it may be assessed by means of appropriate indices. In the contemporary holistic attitude to a patient, in modern oncology, QL has become a parameter of equal importance to other values characterizing the treatment success, as important as numbers describing e.g. mean survival, disease free survival, or neoplasm controlled survival. Head and neck neoplasms bring about deterioration of the basic functions of the organism such as: breathing, swallowing, speaking and senses: hearing, taste and smell. Application of treatment may intensify pain, dyspnea, hoarseness or cause any kind of discomfort. It influences directly the patients' family and social life. Comparison of QL of patients treated for larynx, tongue, tonsill, glands, and paranasal sinuses neoplasms depending on localisation of primary foci, advancement of the disease, the applied treatment and its radicality, age, sex, place of living (town/country), and educational level. Correlation between the subjectively assessed QL and the objectively evaluated condition of the patient is measured. In ENT Dept. K. Marcinkowski University of Medical Sciences 46 patients were examined from May to September 2000. EORTC QLQ C-30, EORTC QLQ-Head and Neck and HAD scale were used. Kiel Questionnaire was introduced in September. The main reason for introducing it was the fact, that surgery is the method of choice in the treatment of head and neck malignancies in our Dept. The team composed of a psychologist and an ENT doctor has been working together on objective assessment of each patient. The QL assessment may be of practical importance when trying to improve the model of health care in cases of oncological patients. This knowledge enables us to learn how the accompanying side effects of therapy influence the QL of our patients, and how these problems may be overcome by proper education, advice, and support provided by the qualified staff. The authors are evaluating the QL in the period of 2, 6 months and 1 year after surgery in patients not supported psychologically. Our goal, in the future, is to introduce the psychological treatment, i.e. repetitive meetings in small groups, conducted by a psychologist. We have contacted 4 major ENT centers in Poland in order to coordinate the research on detailed assessment of QL in Head and Neck Cancer Patients in Poland. The results will be presented in the further publications.

Abstract
BACKGROUND Metalloproteinases (MMP) are endopeptidases, which are able to degrade extracellular matrix. It is assumed that MMP play an important role in invasion and metastasis of malignomas. The expression of collagenase-3, also named MMP-13, was already detected in squamous cell carcinoma of the head and neck, but the significance in the process of metastasis is still unclear. PATIENTS AND METHODS 36 tumor biopsies of oropharyngeal squamous cell carcinoma (10 cases N0, 26 patients N+) and 12 biopsies of normal oropharyngeal mucosa were analysed with reverse transcriptase-PCR and Northern Blot for their mRNA-expression of MMP-13 and TIMP-1, the physiological inhibitor of MMP-13. RESULTS In 30 of 36 (83.3%) tumor biopsies a MMP-13-mRNA-expression was detected. In 9 of 10 (90%) cases with N0-status and 21 of 26 (80.7%) cases with N(+)-neck the mRNA-expression could be shown. There was no correlation between MMP-13-mRNA-expression and N-status. In 34 tumor biopsies (94.4%) a TIMP-1-expression was detected. MMP-13-mRNA was not detected in normal oropharyngeal mucosa. CONCLUSIONS It seems that MMP-13-mRNA-expression is not a prognostic factor for metastatic behavior of oropharyngeal cancer and therefore not helpful for further decisions on the therapy.

Abstract
BACKGROUND Recording procedure of transiently evoked otoacoustic emissions is an important part of diagnostics in pediatric audiology. As a rule of thumb measurable TEOAE excludes more than slight hearing impairment. Nevertheless any interpretation of these measurements in a clinical setting must consider supposed false positive findings (so called pseudoemissions) and real false positive findings in cases of profound hearing loss with reproducible TEOAE and missing auditory evoked potentials. PATIENTS AND METHODS TEOAE recordings in 512 patients were evaluated for recording procedure failure. Possible types of recording procedure failure were divided into failures conditioned by the patients and stimulus or probe dependent failures. In case of insufficient test procedure and absent TEOAE recording procedure was improved and repeated. RESULTS In 2 patients with severe to profound hearing loss we discovered reproducible TEOAE whereas auditory evoked potentials were missing. As a stimulus and probe dependent recording procedure failure we saw reproducible pseudoemissions in 3 other patients with profound hearing loss. CONCLUSIONS These results indicate that conclusions concerning hearing ability on the base of TEOAE should keep in mind possible pseudoemissions as a result of recording procedure failure. Reported cases with absent auditory evoked potentials and reproducible TEOAE showed that TEOAE recordings in these cases indicate substantially preserved outer hair-cell function independent of profound hearing loss.

Abstract
OBJECTIVE To obtain new insights into the pathophysiology of primary acquired dacryostenosis. DESIGN Comparative autopsy tissue study with histopathologic correlations. MATERIALS Tissue specimens from the human nasolacrimal ducts of 36 patients undergoing endonasal dacryocystorhinostomy within a framework of primary acquired dacryostenosis were analyzed by histologic studies and electron microscopic examination. Six lacrimal systems of body donors served as controls. TESTING One group of tissue specimens from each lacrimal system was prepared and processed with paraffin, sectioned, stained by different methods, and finally examined by light microscopy. The other group was processed with araldite after preparation, sectioned semithin and ultrathin, and examined by transmission electron microscopy. MAIN OUTCOME MEASURES The degree of dacryostenosis was scored in each tissue specimen by grading the histologic sections as mild (active chronic inflammation), moderate (proliferative sclerotic forms of chronic fibrosis), or severe (total subepithelial fibrosis). RESULTS Of 36 patients with epiphora, 13 had functional obstruction with a patent lacrimal system on syringing; in 23 cases, the lacrimal passage was completely obstructed. Different pathologic stages correlating to duration of symptoms were found ranging from active chronic inflammation to proliferative sclerotic forms and total subepithelial fibrosis. CONCLUSIONS Descending inflammation from the eye or ascending inflammation from the nose initiates swelling of the mucous membrane, remodeling of the helical arrangement of connective tissue fibers, malfunctions in the subepithelial cavernous body with reactive hyperemia, and temporary occlusion of the lacrimal passage. In the follow-up, repeated isolated occurrence of dacryocystitis leads to structural epithelial and subepithelial changes, which may lead either to a total fibrous closure of the lumen of the efferent tear duct or to a nonfunctional segment in the lacrimal passage that is manifest on syringing.

Abstract
Chemokines in biological sample are frequently found at very low level. Further, concentrations of chemokines which were measured in the same tissue detected with different methods often differ in literature. Therefore, RANTES concentrations were quantified by application of sandwich enzyme-linked immunosorbent assay (ELISA) and Western blot analyses. The sensitivity of ELISA was found to be much higher than that of Western blot. Additionally, the detection time differed considerably as well. For biological and biochemical characterization of chemokines it is essential to implement the optimal purification and detection techniques. With an understanding of the technical procedures and some pitfalls, chemokine detection can be applied more reliably.

Abstract
PURPOSE The aim of the experiments was to analyze the mRNA expression pattern and verify the repression of FN gene expression in laryngeal squamous cell carcinoma (SCC) cells in comparison with benign mucosal keratinocytes. METHODS Messenger RNA from SCC cells and benign keratinocytes was reverse transcribed and subjected to PCR following differential display (DD) analysis of the amplicons. Northern hybridization was carried out to confirm the reduction of the FN-mRNA expression in both laryngeal SCC cells and larynx carcinoma biopsies, in contrast to adjacent normal mucosa. Quantitation of protein synthesis was performed with homogenates of fresh tumor biopsies and their normal phenotypes, as well as of benign keratinocytes and laryngeal SCC cell lines, respectively, using ELISA. In the liposome-mediated transient transfection assay, FN promoter activity was analyzed by linking the FN promoter sequence to the chloramphenicol acetyltransferase (CAT) reporter gene. Transfection efficacy was monitored by co-transfection with pGL3 control vector. RESULTS A 191 bp mRNA fragment revealing a 99% homology with the human FN-mRNA was detected, the expression of which was repressed 20 times as much in SCC cells as compared to benign phenotypes. Northern hybridization confirmed the distinctly reduced expression of FN-mRNA in both laryngeal SCC cells and larynx carcinoma biopsies, in contrast to adjacent normal mucosa. The quantitation experiments showed a correlation between the range of FN synthesis and the expression of FN-mRNA in cell lines and the biopsies which were used. The 1.28 kb FN gene promoter drove expression of the CAT reporter gene, which was similar to the FN-mRNA expression showed by DD and Northern hybridization. CONCLUSIONS The mechanisms leading to the low level of FN in many tumors have not yet been sufficiently investigated. Our findings suggest that the decrease of FN in laryngeal SCC cells is transcriptionally regulated.

Abstract
BACKGROUND The last years are characterized by a change of paradigms in the evaluation of medical therapeutical strategies. The term quality of life (QoL) has been established in oncology and could be demonstrated as a subject of highly qualified investigations which were published during the last years. An extendend quality management is correlated with the possibility of cost-effectiveness measurement and arrangement in a time characterized by decreasing financial resources of the hospitals and university departments. The experiences in the field of quality analysis could offer precious tools to optimize structures, processes and results of treatments. This aim is strongly supported by the expected law "Gesundheitsreform 2000". METHOD AND RESULTS Therefore reliable, valid tools are needed to calculate the effects of therapies. The combination of global and specific questionnaires include the possibility to compare oncologic data of different entities of malignomas. A couple of questionnaires in otorhinolaryngology were developed in the last decade involving the fields of malignomas of the upper aerodigestive tract, rhinosinusitis etc. CONCLUSIONS Ishikawa, the founder of "Total Quality Management" and of the "Quality Circ", pointed out the high importance of customer satisfaction. Whereas the patient is in the mid point of medical treatment there are hardly any investigations about customer satisfaction published. Therefore it is necessary to develop and establish validated tools for the measurement of quality dimensions. The short, middle and long-lasting effects of a treatment could be calculated by quality of life measurements. The QoL is here of very strong importance, especially since economic aspects are included.

Abstract
Human papillomavirus (HPV) infections are related to the genesis of various benign and malignant human neoplasias. The HPV types 16 and 18 seem to be causally related to the development of most squamous cell carcinoma of the anogenital tract and a proportion of carcinomas of the upper aerodigestive tract. The near 100% positivity of the HPV types 6 and 11 in laryngeal papillomatosis is well established. We investigated whether HPV also plays a role in non-neoplastic mucosal entities such as sinunasal polyposis, the genesis of which has been discussed as being triggered by viral infections. On DNA from 39 sinunasal polyps (33 patients), polymerase chain reaction (PCR) was performed using beta-globin primers for demonstration of amplifiable DNA in the tissue extracts. Consensus primers for the detection of several different HPV types were applied to the beta-globin-positive samples. The results were confirmed by Southern blot hybridization using consensus probes. Cycle sequencing was performed on the positive cases. All 39 samples showed positive signals for beta-globin. HPV-DNA investigations showed a slight positive signal in only 1 of the 39 investigated cases (2.6%). Further molecular investigations of this sample, including cycle sequencing, could not confirm this result. All the other tissue samples remained HPV-DNA-negative. Therefore, those HPV types readily detectable with the PCR primers and probes used are not frequently associated with sinunasal polyposis. The data confirm the hypothesis that HPV is correlated to a lesser extent to infectious mucosal lesions than to proliferative lesions. Furthermore, the results emphasize that the presence of HPV in specific lesions does not occur by chance, but represents a specific infection of the mucosa leading to proliferation and even to malignancy.

Abstract
The aim of the present study was a validation of acoustic rhinometry (AR) by computed tomography (CT). Six healthy subjects were examined by CT and AR. The CT data were processed in a computer program (AutoCAD), and a virtual three-dimensional model of each nasal cavity was constructed. This model permitted an individual prediction of the center line of the sound wave propagation through the air volume of the nasal cavity with the cross-sectional areas oriented perpendicularly to this line. The area-distance curves derived from AR and CT were compared. Linear regression analysis revealed a reasonable agreement of AR and CT in the anterior nose below a mean of 6 cm distance from the nostrils [r = 0.839, P < 0.01, m = 1.123, b = -0.113 (AR = m x CT + b)]. The measuring accuracy using CT as gold standard revealed a mean error at the nasal valve of <0.01 cm(2) (4.52%) and at the nasal isthmus of 0.02 cm(2) (1. 87%). Beyond 6 cm, the correlation decreased (r = 0.419), and overestimation of the true area occurred (>100%). In conclusion, the measurements were reasonably accurate for diagnostic use up to the turbinate head region. Certain factors induce an overestimation of the true areas beyond this region. However, these factors are constant and reproducible in a single subject, and intraindividual comparative measurements are possible beyond the turbinate head region.

Abstract
Supporting cells of Corti's organ are electrically coupled via gap junctions. They probably serve to maintain the unique cochlear environment that is required for normal sensory function. In this study we used input capacitance measurements under whole-cell voltage-clamp conditions to evaluate the effects of nitric oxide on gap junctional communication between pairs of isolated supporting Deiters cells. We show that the nitric oxide (NO) donor sodium nitroprusside causes the uncoupling of Deiters cells, and that an NO synthase inhibitor blocks the effect. The cGMP analogue 8-bromo-cGMP also uncouples Deiters cells. With either treatment, the input capacitance of pairs of Deiters cells drops to single-cell levels within minutes of application, indicative of electrical uncoupling. We surmise that the NO/cGMP pathway may serve to modulate normal cochlear homeostasis and possibly plays a role in ototoxic mechanisms.

Abstract
BACKGROUND Lymph node metastasis in the head and neck region with occult primary cancer are a fairly rare tumor entity in head and neck cancer. Tumor biological parameters as well as mechanism and cause for the development of this so called "cancer of unknown primary" (CUP) are not well investigated in head and neck cancer. Mutations of the p53 tumor suppressor gene are the most prevalent genetic alteration of human malignancies and show an incidence of up to 50% in head and neck cancer. For a further tumor biological definition of CUP the p53 status was determined. METHODS Twenty-three archival formalin fixed paraffined CUP of an occult squamous cell carcinoma of the head and neck region were examined. In all cases a primary cancer was never diagnosed. The DNA extracted from the tumor material was amplified with specific primers for exon 4-9 of the p53 gene and subsequently sequenced. RESULTS None of the 23 CUP cases showed a mutation or polymorphism in exon 4-9 of the p53 gene. CONCLUSIONS The total absence of p53 mutations in the so called mutational "hot spots" shows a significant difference to the frequency of primary tumors of the head and neck region. May be this tumor biological characterisation helps to further elucidate the growth behaviour of CUP in the head and neck region and the reason for their development.

Abstract
BACKGROUND Spontaneous enophthalmos without recent trauma is a rare condition. Its origin is difficult to evaluate. METHOD Specific properties of this symptom complex are presented based on a literature review and on case reports. Possible connections between enophthalmos and paranasal sinus diseases as well as differential diagnoses are analysed. PATIENTS 1. 31 year old female patient with right spontaneous enophthalmos and no history of trauma. CT-imaging disclosed tissue formation in the maxillary sinus, partially destroyed medial orbital wall and floor, descended orbital contents following Caldwell-Luc procedure several years previously. After endonasal surgery of ethmoidal and maxillary sinus with removal of a large cyst good functional and cosmetical result. 2. 25 year old male patient complaining of pain in the periorbital region, presenting with left enophthalmos and superonasal deviation of the eyeball. MRI and CT revealed a tumor in the orbital floor region with total destruction of the roof of the maxillary sinus. Removal of the tumor by a combined lateral rhinotomy and subciliary approach. DIAGNOSIS Leiomyoma. Orbital reconstruction with PDS-sheet. Postoperatively, improved globe position and motility. No recurrence during three year follow-up. CONCLUSION When evaluating the causes of enophthalmos, chronic diseases of the paranasal sinuses or their walls must be considered. Surgical therapy is promising.

Abstract
BACKGROUND Chronic sinusitis is one of the frequent inflammatory diseases and has a complex pathogenesis. A substantial factor seems to be recurrent bacterial infections. Pseudomonas aeruginosa (PA) frequently can be found in nasal smears of patients with persistent sinus symptoms after sinus surgery. Lately a new antimicrobial peptide of epithelial origin, human Beta-Defensin-2 (hBD-2), with a strong antibacterial effect against PA could be identified within lesional skin scales of patients suffering psoriasis. Aim of this study was to investigate hBD-2-mRNA expression in nasal cells and tissue. METHODS Total RNA was extracted from nasal polyps and turbinates following TRIzol protocol. Epithelial cells and fibroblasts of nasal human tissue were isolated and cultivated. The cells were stimulated with PA using different time points and different concentrations. Total RNA was isolated as mentioned above, reverse transcribed and amplified in a Semi-quantitative Reverse Transcriptase PCR (SQRT-PCR) with genespecific hBD-2 primers. RESULTS PA induces time- and dose-dependently hBD-2 gene expression in nasal epithelial cells. Unstimulated epithelial nasal cells were able to express hBD-2 mRNA constitutively, whereas nasal fibroblasts showed no hBD-2 mRNA expression. Nasal polyps showed a comparable less hBD-2 gene expression then nasal turbinates. CONCLUSIONS hBD-2 possibly mediates a specific, early starting antimicrobial defense strategy of the nasal mucosa. This hypothesis would explain persistent infections with PA through diminished hBD-2 gene expression.

Abstract
BACKGROUND The insulin receptor (IR) is an essential protein localized on the surface of almost all cell types. IR belongs to the tyrosine-kinase growth factor receptor family. Insulin mediates proliferative responses in a variety of tumor cells, however, the role of the IR molecule in carcinogenesis has not yet exactly been established. METHODS Messenger RNA from mucosal keratinocytes and laryngeal carcinoma cells were transcribed in cDNA using reverse transcriptase and amplified by PCR by means of a number of oligonucleotides. PCR products were analyzed electrophoretically. RESULTS Comparing the electrophoretic pattern of both cell types the overexpression of a 127 bp fragment could be detected in laryngeal carcinoma cells in contrast to benign keratinocytes. Cloning and sequencing this fragment exact homologous match was found with exon-2 of the IR gene. The overexpression of the IR gene in laryngeal carcinoma cells was confirmed by Northern hybridization. CONCLUSIONS The results show up-regulation of IR-mRNA in laryngeal carcinoma cells suggesting that the number of IR is enhanced in these cells. Hence it follows, that the overexpression of IR plays a possible role in laryngeal cancer initiation and/or progression.

Abstract
p53 gene mutations are a common genetic alteration in human cancer and codon 72/exon 4 polymorphism of the p53 gene has been implicated in cancer risk. Therefore in this study the p53 gene status of 32 shock-frozen tumor specimens from larynx carcinomas was analyzed by PCR and sequencing of exon 4 through 9. Four mutations (12.5%) in exon 5, 7, 8 and 9 were detected in the carcinoma specimen. Analysis of codon 72 revealed in eight cases a homozygosity for proline (CCC) and in 24 cases heterozygosity or homozygosity for arginine (CGC). The group with the proline/proline genotype had a median age 10.3 years lower than the remaining patients and included the only two non-smokers. Firstly, these results confirm the p53 mutational status of laryngeal cancer without any clinical correlation and secondly may suggest an oncogenic potential for the proline/proline genotype of codon 72 for laryngeal cancer as has already been assumed for lung cancer.

Abstract
BACKGROUND During the last decades rhinosurgery largely developed up to endonasal accesses. Meanwhile many of the new techniques are established, so that the outcome of traditional extranasal methods should be compared with those of endonasal accesses, in order to estimate the status and for critical consideration. METHODS A retrospective analysis recorded the results of 236 patients, operated on primary frontal sinus disease 1985-1993. The records were consulted concerning inpatient treatment and outpatient aftercare during standardized paranasal sinus consulting hours. RESULTS During the follow-up period (3-10 years) 8% of the patients underwent resurgery. The lowest revision rate was found after using endonasal technique (5.9%), compared with osteoclastic methods (Ritter-Jansen, Riedel: 10.6%). The domain of osteoplastic operations with a revision rate of 9.4% were fractures, osteomas and mucoceles, because of an impossible endonasal access. In decision on osteoclastic procedures, the already osteoclastically operated site was of prime importance, especially since 1990. CONCLUSION Already during the early years endonasal techniques of paranasal sinus surgery showed better outcome than osteoclastic accesses. The analysis indicates that the change to endonasal functional paranasal sinus surgery is justified and should be kept up. The traditional methods still have their rare authorization in case of special indications, especially if an osteoclastic procedure has been carried out already.

Abstract
Cultured lung epithelial cells release antibacterial activity upon contact with Pseudomonas aeruginosa (PA), which is impaired in cystic fibrosis (CF). In order to identify the factors responsible for killing PA by a biochemical approach, we purified antimicrobial activity from supernatants of the A549 lung epithelial cell line, previously stimulated with PA bacteria, by subsequent high performance liquid chromatography. NH(2)-terminal sequencing of a major bactericidal compound revealed it to be identical with human beta-defensin-2 (hBD-2). A mucoid phenotype of PA, but not two nonmucoid PA strains, high concentrations (> 10 microg/ml) of PA lipopolysaccharide, tumor necrosis factor alpha, and interleukin (IL)-1beta, but not IL-6, dose-dependently induced hBD-2 messenger RNA in cultured normal bronchial, tracheal, as well as normal and CF-derived nasal epithelial cells. Genomic analysis of hBD-2 revealed a promoter region containing several putative transcription factor binding sites, including nuclear factor (NF) kappaB, activator protein (AP)-1, AP-2, and NF-IL-6, known to be involved in the regulation of inflammatory responses. Thus, hBD-2 represents a major inducible antimicrobial factor released by airway epithelial cells either on contact with mucoid PA or by endogenously produced primary cytokines. Therefore, it might be important in lung infections caused by mucoid PA, including those seen in patients with CF.

Abstract
p53 autoantibodies (AAB) are a fairly new serological parameter in patients with malignancies. Although the actual mechanism of how they develop is still unclear, it seems that these AAB could be of prognostic relevance. Very few studies demonstrated the usefulness of p53 AAB in the follow-up of cancer patients. In this study, 109 patients with head and neck cancer were investigated using an ELISA for the presence of p53 AAB in their serum and were followed-up for at least 36 months. In 21 of the cancer patients, p53 serum AAB were detected. In 5/21 p53-seropositive AAB patients, a correlation with the clinical course was observed. Sixteen of the p53-positive patients did not show any significant AAB titer changes during the follow-up, and no significant correlation with the clinical course was seen. According to these results, the clinical value of p53 AAB in the follow-up of patients with head and neck cancer seems to be limited.
