Abstract
Destruction of bone by tumour is caused by osteoclasts rather than by tumour cells directly. Tumour cells of invasive oral squamous cell carcinomas (SCC) release osteoclast-related cytokines and cytokines activate osteoclasts. The purpose of this study was to investigate the possibility of predicting mandibular invasion by SCC by analysis of the expression of osteoclast-related cytokines in biopsy specimens of SCC, adjacent or fixed to the mandible. Thirty-five biopsy specimens from the pathology archives were examined from patients who had been treated for SCC, adjacent or fixed to the mandible. The patients were divided into those with and without medullary invasion. The expression of tumour necrosis factor (TNF)-alpha, interleukin (IL)-6 and IL-11 was studied by immunohistochemical analysis. No significant differences were found in expression of TNF-alpha, IL-6 and IL-11 between biopsy specimens with or without medullary invasion. Quantification of the density of tumour-infiltrating lymphocytes was not reproducible. In conclusion, the expression of TNF-alpha, IL-6 and IL-11 in biopsy specimens of SCC, adjacent or fixed to the mandible, is not an appropriate method for predicting the presence of medullary invasion of the mandible.

Abstract
INTRODUCTION In recent years, there has been an increase in the number of patients with squamous cell carcinoma (SCC) of the mobile tongue in the absence of tobacco and alcohol. The literature suggests that human papilloma virus (HPV) may be involved in the development of SCC of the head and neck, especially in non-smoking and non-drinking patients. In the oral cavity, however, the presence of the HPV genome has been reported with various percentages. This may be due to misclassification of the oropharyngeal tongue as oral cavity subsite and the use of various detection methods. MATERIALS AND METHODS Therefore, we evaluated the role of HPV in seven consecutive non-smoking and non-drinking patients (2003-2006) with a SCC located at the oral, mobile tongue using in situ hybridization and SPF(10)Line Blot 25 polymerase chain reaction assays. RESULTS No HPV was detected in these specimens. To further determine whether a relationship exists between HPV and SCC in the absence of tobacco and alcohol, subsequent studies at specific locations are necessary.

Abstract
OBJECTIVES Progression and regression of premalignant cervical lesions cannot be predicted using conventional cytomorphological or histomorphological parameters. However, markers such as human papillomavirus (HPV) or makers indicating proliferation, genetic instability and chromosomal aberration may be of predictive value assessing short-term biological behavior of cervical intraepithelial neoplasia. In this paper, we have studied the usage of logistic regression models with Ki-67 labeling index (LI), chromosome index for chromosome 1 (CI#1) and aneusomy for chromosome 1 in cervical smears to predict progressive and regressive behavior of premalignant cervical lesions. METHODS Retrospectively, the intake smears of 42 women showing regression in follow-up and of 31 women showing progression in follow-up were assessed. RESULTS A multiparameter logistic regression model containing the parameters Ki-67 LI, CI#1 and the fraction of cells with four copies of chromosome 1 per nucleus appeared to be the best predicting model, overall correct classification of 93.2% (area under the receiver operating characteristic curve 0.96 +/- 0.02). After cross-validation, the model correctly classified 66 of 73 samples (90.4%). Moreover, the model predicted biological behavior perfectly assessing the smear taken subsequently to the intake smear of 46 women. CONCLUSION Although measuring parameters indicating proliferation and chromosome 1 aberration is laborious, this study demonstrates that short-term progressive and regressive behavior is highly predictable using a model combing these parameters. We also showed that in the triage management of high-risk human papillomavirus-positive women with minimally abnormal smears applying a model as such can be useful.

Abstract
Two separate pathways leading to vulvar carcinoma have been suggested. First, a human papillomavirus (HPV)-dependent pathway, in which premalignant stages of vulvar cancer are the classic vulvar intraepithelial neoplasia (VIN) lesions. Second, an HPV-independent pathway, associated with differentiated VIN III lesions and/or lichen sclerosus. To obtain insight into the mechanisms underlying these pathways, we determined the relationship between HPV DNA and the expression of p14(ARF) and p16(INK4A) in non- and (pre)malignant vulvar lesions. Seventy-three archival samples of non- and (pre)neoplastic vulvar lesions were selected and tested for hr-HPV DNA using a broad-spectrum HPV detection/genotyping assay (SPF(10)-LiPA) and the expression of p14(ARF) and p16(INK4A). The prevalence of HPV increased with the severity of the classic VIN lesions; in VIN I no hr-HPV was detected, in VIN II 43%, and in VIN III 71% of the samples were hr-HPV-positive. Roughly the same was true for the expression of p14(ARF) and p16(INK4A). The simultaneous expression of p14(ARF) and p16(INK4A) was highly associated with the presence of hr-HPV DNA. Hr-HPV was detected in only a single case of the differentiated VIN III lesions, whereas no expression of p14(ARF) was found and 16(INK4A) was present in only two cases. All 16 samples of vulvar cancer were hr-HPV DNA- negative, although in respectively 63% and 25%, p14(ARF) and p16(INK4A) was expressed. No relation was found between hr-HPV and the expression of p14(ARF) and p16(INK4A) in the 20 nonneoplastic vulvar lesions. Our results provide further evidence that vulvar squamous cell carcinoma is a multifactorial disease that develops from two different pathways. First, an HPV-dependent pathway with a remarkable resemblance to CIN lesions and cervical carcinoma and second, an HPV-independent pathway in which differentiated VIN III lesions that are hr-HPV-negative may be precursors.

Abstract
To consider the value of prognostic factors in the development of a squamous cell carcinoma from a leukoplakia of the oral mucosa, a retrospective study was performed. Clinical and histological data of 104 patients with oral leukoplakia were analyzed. Leukoplastic lesions with dysplasia in the initial biopsy (n = 38) had been treated by excision (n = 28), by laser evaporation (n = 6) or a combination of these treatments (n = 4). Non-dysplastic lesions (n = 66) had been excised (n = 48), evaporised (n = 17) or treated by excision as well as laser evaporation (n = 1). During follow-up of maximal 6 years (mean 3.6 years), 12 patients had developed an infiltrative squamous cell carcinoma at the site of the primary lesion, 2 within a period of 24 months. No relation could be found between on the one hand size (p > 0.2), clinical aspect (p > 0.2), location (p > 0.45), and primary treatment (p > 0.15) of the lesion, and on the other hand the risk of developing a squamous cell carcinoma. Only a relation could be found between (the intensity of) dysplasia and the development of a squamous cell carcinoma (p < 0.001). It was concluded that because of the high risk of developing a squamous cell carcinoma, patients with a dysplastic mucosal oral lesion should be followed during a prolonged time.

Abstract
The clinical, radiographic, and pathological features of a juxtacortical chondrosarcoma of the mandible in a 25-year-old Caucasian woman are presented and the differential diagnostic aspects are discussed. To the best of our knowledge, this rare tumor has not previously been reported in the maxillofacial skeleton. Ten years after surgery there is no evidence of local recurrence or metastatic disease. As the prognosis of juxtacortical chondrosarcoma of the long bones seems to be relatively favorable compared with the usual central chondrosarcoma of similar grade of malignancy, this might also be expected for a similar tumor presentation in the maxillofacial skeleton.

Abstract
PURPOSE To study the alterations in hormonal sensitivity in relation to proliferative activity during the development of cervical dysplasia in women infected with high-risk human papillomavirus (hr-HPV). METHODS Three to five biopsies of the cervix of eight patients were taken at colposcopy. Dysplasia was detected in 22 of the 32 biopsies, and 20 of these 22 biopsies contained hr-HPV. The labeling index (LI) as well as the intensity of staining of the MIB-1-, estrogen receptor (ER)-, and progesterone receptor (PR)-expression was assessed in each biopsy, including normal epithelium directly adjacent to the dysplastic lesions. RESULTS Statistical analysis showed a significant increase in the MIB-1 LI with increasing severity of the dysplasia. The ER LI and ER intensity of staining in dysplastic lesions, as well as in morphologically normal epithelium directly adjacent to the dysplasia, showed a significant inverse relation with the severity of the dysplasia. The PR LI and intensity of staining did not differ between normal epithelium and dysplasia. The ER/MIB-1 ratio (including the ER LI and ER intensity of staining), and the PR/MIB-1 ratio (intensity of staining only) in dysplastic lesions showed a significant inverse relation with the severity of the dysplasia, while no alterations in these ratios were observed in morphologically normal epithelium adjacent to the dysplasia. CONCLUSION Down regulation of ER expression may be the first alteration to take place in normal epithelium during the development of cervical dysplasia in women infected with hr-HPV. The significant decrease in the ER/MIB-1-, and PR/MIB-1-ratio in progressively dysplastic lesions indicates a loss of normal growth control by sex steroid hormones, which is not observed in normal epithelium.

Abstract
OBJECTIVE Fibroosseous lesions are rare entities of the nose and paranasal sinuses, the terminology and classification of which are still confusing. Psammomatoid or aggressive (juvenile) ossifying fibroma is a benign messenchymal tumor usually met in the young age (5-15 years), in the sinonasal tract, bearing distinctive histomorphologic features and a tendency towards locally aggressive behaviour. METHODOLOGY We report here a rare case of an aggressive psammomatoid ossifying fibroma of the inferior turbinate and the lateral nasal wall, with obstruction of the nasolacrimal duct, in a 68-year-old woman. RESULTS Diagnosis was based on physical examination, CT scan imaging and histopathological examination. Treatment consisted of endoscopic intranasal resection of the tumor accompanied by removal of the lateral nasal wall. CONCLUSIONS Fibro-osseous tumors of the nose and paranasal sinuses require aggressive surgical approach in order to avoid recurrence. Complete surgical excision may not always be possible mainly due to the tumor's extent and location.

Abstract
In a retrospective analysis of 339 patients, treated with a curative intention for a squamous cell carcinoma of the oral cavity between 1988-1996, the value of a half-yearly routine chest radiograph during the first 2 years of follow-up, was evaluated. Metastatic or primary lung malignancies developed in 18 (5.3%) of the 339 patients in the first 2 years of the follow-up. In 11 (3.2%) patients these malignancies were detected on routine chest radiographs while in 7 (2.0%) patients these were detected on chest radiographs taken because of pulmonary complaints. The mean survival after detection of the pulmonary malignancy was 8 months. All patients died within 21 months, independent of pathology or therapy. No correlation was found between stage, location or differentiation of the primary tumour. As a result of this study it can be concluded that there is no benefit for the patient for a 6-month thoracic radiograph in routine follow-up for patients with oral squamous cell carcinoma. It gives false certainty and burdens the health care system.

Abstract
OBJECTIVE Increasing the accuracy of the diagnosis of Sjögren's syndrome (SS) by placing emphasis on objective findings such as the presence of anti-Ro and anti-La autoantibodies and abnormal salivary gland tissue (SGT) histology is a current issue. In order to obtain optimal disease sensitivity and specificity of SGT findings, histological and immunohistological SGT examinations were compared. The first describes the extent of the lymphocytic infiltrate as a focus score (LFS), whereas the latter describes the composition of the infiltrate as a percentage of IgA-containing plasma cells (IgA%). METHODS Both the LFS and IgA% score were assessed in 279 SGT biopsies taken from patients with symptoms suggestive of SS. In case histological conclusions did not match immunohistological conclusions patients were assigned to so-called mismatch groups. Patients in the mismatch groups were further classified using objective, serological parameters [rheumatoid factor (RF), anti-Ro, anti-La, anti-nuclear antibodies, gammaglobulin level]. RESULTS In 249 samples (89%), LFS and IgA% resulted in the same conclusion. Within this group a total of 63 SGT samples (25%) were characteristic for SS showing LFS >1.0 and IgA% <70. In the mismatch groups after serological classification, both false positive as well as false negative scores were observed less frequently for IgA% as compared with LFS (50 vs 75% and 25 vs 50%, respectively). CONCLUSIONS Additional immunohistological SGT examination provides greater disease sensitivity and specificity than histological SGT examination alone, thereby increasing accuracy of SS diagnosis.

Abstract
BACKGROUND After the menopause decreased concentrations of oestrogen may result in insufficient maturation of the vaginal epithelium, which can lead to a range of vaginal discomforts. This state of vaginal atrophy may be treated with oestrogen replacement treatment. Replens, a non-hormonal alternative to oestrogen replacement treatment has been shown to be effective in relieving symptoms related to vaginal atrophy in previous studies. AIMS To study the effect of Replens on the maturation of the vaginal epithelium and morphology of the vaginal cells and to compare the results of a recently developed cytomorphometric method with manual assessment of the degree of maturation in vaginal smears. METHODS Vaginal smears from 38 postmenopausal women suffering from symptoms related to vaginal atrophy were analysed manually and by cytomorphometry. The maturation value (MV) and the percentages of (para)basal, intermediate, and superficial cells (maturation index; MI) were measured by both methods before and after treatment with Replens. Cytomorphometry also measured mean cellular area, mean nuclear area, and mean area ratio. RESULTS A correlation was shown between the two methods in the assessment of percentages of (para) basal and intermediate cells and MV. Cytomorphometric data showed a significant increase in mean cellular area, indicating a positive effect of Replens on the maturation of the vaginal epithelium. Changes in nuclear area and ratio between nuclear and cellular areas were not significant. Treatment with Replens did not influence MI or MV, as assessed by the two methods. CONCLUSIONS Replens did have an effect on vaginal morphology. The automated procedure may be useful for the assessment of maturation in vaginal smears and is more sensitive to small (subvisual) changes.
