Background: Eating disorders (ED) are a group of psychopathological disorders affecting patient relationship with food and her/his own body, which manifests through distorted or chaotic eating behavior; they include anorexia nervosa, bulimia nervosa and ED not otherwise specified and may be burdened with life-threatening complications. As oral manifestations of ED can occur in many phases of disease progression, they play a significant role in assessment, characterization and prognosis of ED., Methods: Mucosal, dental, and salivary abnormalities associated with ED have been reviewed. Relations between oral menifestations and pathogenesis, management and prognosis of ED have been critically analysed., Results: Oral manifestations of ED include a number of signs and symptoms involving oral mucosa, teeth, periodontium, salivary glands and perioral tissues; differences exist between patients with anorexia and bulimia. Oral manifestations of ED are caused by a number of factors including nutritional deficiencies and consequent metabolic impairment, poor personal hygiene, drugs, modified nutritional habits and underlying psychological disturbances., Conclusion: Oral manifestations of ED can cause impairment of oral function, oral discomfort and pain, and an overall deterioration of aesthetics and quality of life. Their treatment can contribute to overall patient management and prognosis.

Objective: To assess the occurrence of oral pathological changes and symptoms in patients affected by gastro-oesophageal reflux disease (GERD)., Patients and Methods: 200 patients with GERD and 100 matched healthy controls were studied. Thorough visual examination of the dental and oral mucosal tissues was performed and medical history relevant to oral symptoms was collected. The primary outcome was defined as a statistically significant difference, between the study group and controls, in the presence of the following indicators: soft/hard palate and uvula erythema, tooth wear, xerostomia, oral acid/burning sensation, subjective halitosis and dental sensitivity. Statistical analysis included chi-squared test, and crude odds ratio with 95% CI., Results: Univariate analysis showed that xerostomia, oral acid/burning sensation, subjective halitosis, and soft and hard palate mucosa and uvula erythema were more common in patients with GERD than matched controls (P < 0.05)., Conclusions: This study failed to find any significant association between GERD and dental erosions, whereas some symptoms and other objective oral mucosal changes were found to be significantly associated with GERD.

Nodular fasciitis is an uncommon tumor-like fibroblastic proliferation that occurs rarely in the head and neck region. A new case of nodular fasciitis occurring in the cheek of a 56-year-old woman is reported. The case was characterized by dental trauma preceding the appearance of the lesion (extraction of tooth 35). Histologically, the lesion consisted of proliferating fibroblasts and myofibroblasts presenting clinically as a rapidly growing subcutaneous nodule. A conservative surgical excision with curettage is the treatment of choice, and the lesion usually does not exhibit a tendency to recur. The clinical relevance of this condition relies on the fact that both the disorder and its surgical treatment may cause tissue distortion resulting in aesthetic compromise. Furthermore, it needs to be differentiated from malignancy due to its very rapid growth, its rich cellularity, and its high mitotic activity. Both of these aspects, i.e. aesthetic implications and differential diagnosis, have been discussed.

Objectives: The protective role of saliva in the case of oesophageal exposition to gastric acid has long been studied but some contradictions still remain. The main end-point of this study was to evaluate if a qualitative and quantitative alteration in salivary secretion exists in patients affected by GERD., Methods: One hundred and twenty patients (T group) with clinically and endoscopically diagnosed GERD, and 98 healthy subjects (C group) have been evaluated; salivary tests (i.e. basal flow rate, stimulated flow rate, pH, [Na(+)] and [K(+)]) were performed, socio-demographical variables and oral GERD-related symptoms were taken into account. SPSS 10.5 software was used for statistical univariate and multivariate analyses., Results: GERD patients and controls were found to have a similar basal flow rate but different stimulated salivary function [T group mean value 0.989 ml/min (+/-0.48718) vs. C group 1.2197 ml/min (+/-0.6108), pH [T group mean value 8.935 (+/-0.471) vs. C group 7.879 (+/-0.526)] and a higher K(+) concentration. In GERD patients we also registered a significant association with xerostomia [69/120 (57.5%) vs. 28/98 (28.7%)] and an oral burning sensation [58/120 (48.3%) vs. 19/98 (19.3%)]., Conclusions: Our findings assess that salivary secretion is altered in GERD patients and highlight the need for further investigations in order to define the role of saliva in the etiopathogenesis of GERD.

Objectives: Recently, jawbone osteonecrosis has been reported as a potential adverse effect of bisphosphonates administration. This paper considers and highlights histopathologic and radiologic features of this condition., Study Design: Eleven patients, owing to unresponsiveness to conservative treatment and uncontrollable pain, underwent surgical resection of diseased jawbone after extensive hyperbaric oxygen therapy. A thorough clinical, laboratory, and imaging study was performed. Surgical specimens underwent histopathologic and immunohistochemical evaluation., Results: Computerized tomography (CT) scans showed increased bone density, periosteal reaction, and bone sequestration in advanced stages. With magnetic resonance imaging (MRI), exposed areas showed a low signal in T1- and T2-weighted and inversion recovery images, which suggests low water content and is histopathologically correlated with paucity in cells and vessels (osteonecrotic pattern). Unexposed diseased bone was characterized by T1 hypointensity and T2 and IR hyperintensity, which suggests high water content and inflammation, associated with hypercellularity, osteogenesis, and hypervascularity (osteomyelitic pattern)., Conclusions: Diseased bone extends beyond the limits of the bone exposed in the oral cavity. Histopathologic examination correlated well with CT and MRI, which are the choice for the evaluation of bisphosphonate-associated jawbone osteonecrosis.

The term desquamative gingivitis (DG) refers to a clinical manifestation that can be caused by several disorders. Many of them are immunologically mediated; in addition to the oral cavity, they can affect extraoral mucocutaneous sites, e.g., larynx, conjunctiva, esophagus, nasal and genital mucosa, and the skin. The degree of oral, periodontal, and systemic involvement determines the overall morbidity and, sometimes, the mortality of these disorders. We comprehensively review disorders commonly associated with DG and highlight diagnostic pathways, guidelines for differential diagnosis, and oral, periodontal, and systemic implications. More rare conditions are reviewed as well. Mucous membrane pemphigoid, oral lichen planus, and pemphigus vulgaris are responsible for the majority of cases of DG. In addition, other uncommon disorders should be considered. Accurate clinical, histologic, and serologic investigations are often required to differentiate among DG-associated disorders, provide adequate therapy, and improve the prognosis of patients.

Background: Careful endoscopic classification of macroscopic appearance of superficial neoplasias of the gastrointestinal tract is essential in the early detection and appropriate treatment of cancer. It has contributed to introduce minimally invasive endoscopic surgery and has significantly improved survival of patients with colon and gastric cancers. Squamous cell carcinoma of the oral cavity has been characterized, in past and present times, by poor prognosis and lack of progress in treatment outcome. Failure in diagnosing oral malignancy at an early stage is a major culprit, and the lack of a worldwide adopted classification of its macroscopic appearance, similar to that of gastrointestinal neoplasias, may have contributed to it., Aim: To test the hypothesis that is possible to extend the diagnostic benefit of a classification based upon the macroscopic appearance of superficial tumours of the digestive tract to superficial carcinoma of the oral mucosa., Methods: We retrospectively examined a group of patients who developed multiple intraepithelial and early invasive malignant oral neoplasias, applying a modified version of the Paris classification of superficial GI neoplastic lesions., Results: One hundred and ten out of 116 (94.9%) of the study lesions had morphological features that accorded with the prepared classification., Conclusions: These preliminary data suggest that most superficial early neoplastic lesions of the oral cavity can be easily detected using a well-defined classification system similar to that employed in the diagnosis of early gastrointestinal malignancy.

Background: Osteonecrosis of the jaw is a well known potential complication of bisphosphonate treatment but its pathogenesis is poorly understood. The current management of patients with bisphosphonate-associated osteonecrosis (BON) is based on "expert recommendations" and there is a recognized need of better evidence. We report two cases where BON hid jaw metastases and use them to discuss some limitations of the current recommendations., Patients: Two patients undergoing long-term I.V. amino-bisphosphonate treatment for metastatic cancer presented with areas of intraorally exposed jawbone. Bisphosphonate-associated osteonecrosis was diagnosed on the basis of medical history, clinical and radiological features. They underwent surgical resection of the affected jaw due to unrelenting pain and lack of response to conservative treatments., Results: Histological examination of the surgical specimen revealed cancer cells at the margins of the site of osteonecrosis. Our patients did not undergo bone biopsy according to current recommendations, due to lack of clinical and radiological signs suggestive of jaw metastases., Conclusions: Our findings show that: i) patients with BON may also have jaw metastases; ii) there may not be clinical or imaging hints to this fact and; iii) that a biopsy based on careful selection of the site (with inclusion of necrotic margins) may be needed to reach the correct diagnosis. Further studies should be performed on this topic because of its very important prognostic implications.

The incidence of eating disorders has progressively increased over the last several years, mainly affecting both the health and quality of life of young women. Such disorders are primarily an outlet for manifest psychic suffering and secondarily, they jeopardize the integrity and function of multiple organ systems resulting in significant morbidity and sometimes, life-threatening outcomes. The complex emerging interplay of etiopathogenetic factors poses many challenges in their prevention and management, which is further complicated by a reluctance by patients with eating disorders to seek medical evaluation and treatment. Recognition of the oral manifestations is important because these signs and symptoms can provide insights about disease progression and parallel general health and psychic status. Oral health care providers may be one of the few providers contacted by this patient population seeking recall prophylaxis or urgent dental care. Thus, improving understanding and knowledge of both general medical aspects of eating disorders and their oral manifestations could be of great impact in elevating the attention of health providers towards this group of very debilitating disorders and, consequently, improving their overall prognosis. In this paper we will review and discuss all these aspects.

Detection of a broad number of respiratory viruses is not undertaken currently for the diagnosis of acute respiratory infection due to the large and always increasing list of pathogens involved. A 1-year study was undertaken on children hospitalized consecutively for acute respiratory infection in a Pediatric Department in Rome to characterize the viruses involved. Two hundred twenty-seven children were enrolled in the study with a diagnosis of asthma, bronchiolitis, bronchopneumonia, or laringo-tracheo bronchitis. A molecular approach was adopted using specific reverse transcription (RT)-PCR assays detecting 13 respiratory viruses including metapneumovirus (hMPV) and the novel coronaviruses NL63 and HKU1; most amplified fragments were sequenced to confirm positive results and differentiate the strain. Viral pathogens were detected in 97 samples (42.7%), with 4.8% of dual infections identified; respiratory syncytial virus (RSV) was detected in 17.2% of children, followed by rhinovirus (9.7%), parainfluenza virus type 3 (PIV3) (7.5%), and influenza type A (4.4%). Interestingly, more than half the patients (9/17) that have rhinovirus as the sole respiratory pathogen had pneumonia. HMPV infected children below 3 years in two peaks in March and June causing bronchiolitis and pneumonia. One case of NL63 infection is described, documenting NL63 circulation in central Italy. In conclusion, the use of a comprehensive number of PCR-based tests is recommended to define the burden of viral pathogens in patients with respiratory tract infection., ((c) 2007 Wiley-Liss, Inc.)

Background: The concept of field cancerization describes the tendency of patients with premalignant and malignant lesions of head and neck mucosal sites to develop multiple carcinomas of the upper aerodigestive tract. Here we address whether this concept should be extended also to patients affected by oral lichen planus (OLP), an inflammatory disorder associated with an increased risk of cancer development., Methods: Data from a cohort of 45 patients with OLP who subsequently developed severe dysplastic changes and/or oral squamous cell carcinoma were retrospectively reviewed. Patients who presented more than one oral neoplastic event were considered for further data analysis as regards incidence, localization, management and prognosis., Results: Twenty (44.4%) patients were affected by one single neoplastic event while 25 (55.6%) developed multiple and often multifocal oral dysplastic and/or malignant events. In most cases, a careful surveillance programme led to diagnosis and effective treatment of oral neoplasias at an early intraepithelial and microinvasive stage, leading to long-term survival. In some patients, however, additional primary tumours occurred suddenly with rapid invasion, leading to advanced stage diagnosis and poor prognosis. Overall, three patients (12%) died due to malignant oral disease., Conclusions: Patients with OLP and subsequent development of dysplasia/ oral squamous cell carcinoma are at risk of having multiple and multifocal neoplastic events of the oral cavity, a phenomenon which parallels the concept of field cancerization of traditional head and neck cancers. If detected at an early stage, these neoplasias can be managed with superficial and complete resection. However a small number of patients have loco-regional tumour spread despite a standard surveillance protocol.

Introduction: The present study was undertaken to evaluate the safety and effectiveness of a recently developed electrostimulating device mounted on an individualized intra-oral removable appliance., Materials and Methods: The device, containing electrodes, a wetness sensor, an electronic circuit and a power source, was tested on patients with xerostomia in a crossover, randomized, sham-controlled, double-blinded, multicenter study. Electrical stimulation and also sham were delivered during 10 min to the oral mucosa, in the mandibular third molar region. Oral dryness was measured by the sensor. As the primary outcome, sensor dryness and xerostomia symptom changes as a result of device wearing were assessed, and compared between active and sham modes. In addition, side-effects were recorded., Results: Electrostimulation resulted in a significant decrease in sensor dryness, leading to a beneficial effect on patients' subjective condition. No significant side-effects were observed.

The concept of dysplasia/neoplasia surveillance has been applied to long-standing conditions associated with an increased risk of cancer. Although still controversial, periodic direct clinical examination as well as endoscopic techniques are currently performed in patients with inflammatory bowel diseases, Barrett's esophagus, and melanocytic skin lesions in order to detect and treat dysplastic or early malignant changes and therefore improve the patients' prognosis. It is not known if patients with oral lichen planus (OLP), a chronic inflammatory condition associated with an increased risk of cancer development, might benefit from such surveillance as well, nor how this should be performed. Here we present the clinical criteria we have adopted over a 12-year period to detect early malignant transformation of OLP, and report on their impact on the management and prognosis of patients. Overall data from 45 patients affected by 117 neoplastic events arising from OLP have been evaluated. Our dysplasia/neoplasia surveillance has led us to diagnose most episodes (94.9%; n.: 111) of OLP malignant transformation in early intraepithelial and microinvasive phases, namely stage 0 and I oral cancers (T(is) N0M0 or T1N0M0). The 5-year survival rate, where applicable, has been 96.7%. Advanced stage oral cancers have been diagnosed in six patients, three of whom have died. We suggest that the application of strict and rigorous clinical criteria in dysplasia/neoplasia surveillance could help clinicians to detect and treat early OLP malignant transformation and therefore improve long-term survival rates. Nevertheless, a small subgroup of patients has been shown not to benefit from such surveillance and to be characterized by a rapid development of advanced-stage oral carcinomas, with consequent poor prognosis.

Although respiratory syncytial (RS) virus is the major cause of bronchiolitis and pneumonia in young children, the factors that regulate the associated lung inflammation have not been defined. The levels of interleukin (IL)10, IL-12, and interferon (IFN) were determined in the nasal wash samples from 20 infants with a clinical diagnosis of bronchiolitis, seven with confirmed RS virus infections and 9 control children without respiratory illnesses. IL-10 levels were significantly higher in acute nasal wash samples (1-4 d post hospitalization) from RS virus-infected infants than in convalescent samples from these children (14-21 d post-hospitalization), from children with other forms of bronchiolitis and from control children. In contrast, only one RS virus-infected infant had detectable IL-12 in an acute nasal wash sample. IFN activity was not detected in any samples from RS virus-infected children. RS virus infection stimulates IL-10 expression but not IL-12 and IFN, possibly contributing to an ineffective cell-mediated immune response.

Background: Oral lichen planus (OLP) is one of the most common oral mucosa disorders. OLP gingival involvement is very frequently observed, and it is characterized by wide variations in clinical appearance and symptoms, leading, in many cases, to misdiagnosis or undiagnosis. This can be potentially harmful since OLP patients require appropriate management in oral and periodontal care, together with an adequate systemic evaluation., Objective: In this paper, we have analysed the prevalence and clinical aspects of gingival lesions in our series of 700 patients affected by OLP. Furthermore, we have discussed the possible periodontal implications on the basis of the available literature., Patients and Methods: Data from 700 patients affected by OLP, clinically and histologically assessed, have been studied; the location and morphology of lesions, the symptoms and the progression of the disease have been considered, with particular attention given to gingival involvement., Results: Gingival lesions have been diagnosed in 48% of cases, usually associated with diffuse oral involvement. Only 7.4% of patients had OLP lesions confined to the gingiva. The morphology of lesions included all the forms originally described for OLP (reticular, papular, plaque, atrophic, erosive and bullous). The symptoms, if present, varied from mild discomfort to severe oral pain, with the general trend increasing from the keratotic to the erosive forms. The gingiva was involved in four out of 21 of our oral cancer cases, which developed from pre-existing OLP lesions., Conclusion: OLP is a very proteiform disorder; considering the high frequency of gingival involvement and its influence on oral health, it is our opinion that periodontologists should be involved in OLP management and should become familiar with its clinical aspects and related themes.

Background: Gorham's disease is a rare disorder characterized by spontaneous and progressive osteolysis of one or more skeletal bones. The radiographic findings associated with Gorham's disease are particularly dramatic, as in some cases a complete resorption of the involved bone can occur, leading to the definition of phantom bone, vanishing bone, or disappearing bone disease., Material and Methods: A 24-year-old female patient with a previous diagnosis of periodontal disease and progressive mandibular alveolar bone loss was referred to our Oral Medicine section. The initial radiographic picture showed infrabony defects and horizontal bone loss., Results: After further extensive local and systemic evaluation, including histopathological, laboratory and imagine techniques investigations, the patient was diagnosed to be affected by Gorham's disease. Meanwhile the progression of the osteolytic process had caused the loosening of all the left mandibular teeth and a pathologic fracture. Appropriate medical therapy was successful in stabilizating the resorptive process, with no evidence of further progressive disease., Conclusions: When Gorham's disease involves the mandible, the role of the periodontologist is extremely important in diagnosing promptly the disorder and preventing the functional and aesthetic consequences of advanced and extensive bone loss. Gorham's disease should be included among the pathologic entities mimicking periodontal disease on radiograph, such as inflammatory disease (e.g. osteomyelitis), endocrine disease (e.g. hyperparathyroidism), intra-osseous malignancies or metastases, lymphoma, histiocytosis X, mainly eosinophilic granuloma, infective process (e.g. tuberculosis and actinomycosis), odontogenic tumours.

Gorham's disease (GD) is a rare disorder characterized by spontaneous and progressive osteolysis of one or more bones and thought to belong to lymphangiomatoses spectrum of diseases. Surgical, radiation and medical therapies have been performed with variable and often discouraging outcomes and currently there is no recognized effective treatment. In this paper we describe a 24-year-old girl with GD localized to mandible who was effectively managed with zoledronic acid, a nitrogen-containing high-potency bisphosphonate.

Aims: To evaluate the occurrence of professional delay in the diagnosis, referral, and treatment of patients with burning mouth syndrome (BMS)., Methods: Fifty-nine patients (51 women and 8 men; average age, 60.5 years; age range, 32 to 88 years) diagnosed with BMS at our institution were retrospectively studied. Data were collected about the onset of oral symptoms, consultations with medical and dental practitioners, and misdiagnosis before definitive BMS diagnosis and treatment., Results: The average delay from the onset of the symptoms to definitive diagnosis was 34 months (range, 1 to 348 months; median, 13 months). The average number of medical and dental practitioners consulted by each patient over this period and who initially misdiagnosed BMS was 3.1 (range, 0 to 12; median, 3). Candidiasis and aspecific stomatitis were the most frequent misinterpretations of the symptoms before appropriate referral. In about 30% of cases, no diagnosis of the oral symptoms was made or explanation given., Conclusion: Professional delay in diagnosing, referring, and appropriately. managing BMS patients occurred frequently in the group studied. No significant differences were found in the number of medical and dental practitioners who were consulted. Emphasis must therefore be placed upon educational efforts to improve health care providers' awareness of BMS. This should increase the rate of recognition and appropriate referral or treatment of patients with chronic orofacial pain due to BMS.

Sjögren's syndrome (SS) is a systemic autoimmune exocrinopathy that affects mainly the salivary and lacrimal glands, leading to progressive reduction in saliva and tear flow. Although the underlying immuno-mediated glandular destruction is thought to develop slowly over several years, a long delay from the start of the symptoms to final diagnosis has been frequently reported. A limited knowledge concerning SS natural history is among the major causes of the actual diagnostic delay. Although very few studies have been focused on the analysis of SS early clinical onset, a series of oral features preceding xerostomia/hyposalivation development in patients eventually diagnosed as having SS have been reported. Sialochemistry alterations, salivary gland swelling, early dental loss and sialorrhea have been observed before the onset of typical signs and symptoms (namely xerostomia and/or hyposalivation), which usually lead to SS clinical presentation and diagnosis. Here we suggest, after evaluating available data, that the traditional 'untouchable' association between SS and xerostomia/hyposalivation might probably be reconsidered, and that astute clinicians should not underestimate the possible presence or development of SS in patients without xerostomia/hyposalivation and presenting these atypical early oral features.

Oral lichen planus (OLP), an immune-mediated disorder, has been reported as an extra-hepatic manifestation of Hepatitis C virus (HCV) infection, especially in HCV hyperendemic areas such as southern Europe and Japan. The aim of this study was to investigate from an epidemiological standpoint whether HCV infection is an important factor affecting the relative risk of OLP in a Mediterranean population or whether this relates to the degree of HCV endemicity. Two cohorts of OLP patients resident in two different regions of southern Italy (Campania and Sicily; n = 859) were evaluated for HCV infection status and categorized into five age classes to respective region-matched controls. No significant difference was found between OLP patients and the general population in this area, when data were corrected by the age-stratified prevalence of HCV. Therefore, the age-specific prevalence of HCV infection in OLP patients shows a close trend of direct association with increasing age, without significant differences with the general population of each geographical area. An aetiological link between OLP and HCV cannot be inferred solely by epidemiological data.

Background: Orofacial granulomatosis (OFG) is an idiopathic disorder characterized by chronic orofacial swellings causing significant cosmetic and functional problems. Treatment with high-volume triamcinolone injections has been shown to be effective but requires nerve block anesthesia and causes a dramatic temporary increase of lip swelling., Objective: We have performed a noncomparative open-label pilot study in 7 patients with OFG in order to evaluate the effectiveness of small volumes of extended-release high-concentrate triamcinolone injections in reducing lip swelling and preventing recurrences., Methods: Seven patients with OFG were studied. Small-volume, intralesional, high-concentrate, extended-release triamcinolone was injected on the basis of a weekly schedule. A standard cycle consisted of 2 or 3 injection sessions over 14 or 21 days, depending on the clinical response., Results: After cycle completion, all patients remained without recurrences or with cosmetically acceptable slight lip enlargement for a mean time of 19 months (range, 8-30 months). No side effects were observed, except in one patient with hypopigmentation of the skin of the upper lip., Conclusions: Slow-volume, intralesional, high-concentrate, extended-release triamcinolone injections appear to be effective in reducing lip enlargement in patients with OFG and do not require nerve block anesthesia or cause a temporary troublesome increase of swelling. A long disease-free period is generally obtained.

In patients affected by alimentary disorders sialadenosis is frequently observed. This non-inflammatory condition is described to affect major salivary glands, leading to the characteristic parotid and/or submandibular swelling. Thus fine-needle aspiration cytology or parotid open biopsy are generally required to diagnose histologically the disorder. We report the case of a 28-year-old patient affected by bulimia/anorexia nervosa who presented, in addition to parotid enlargement, a bilateral symmetric painless soft swelling of the hard palate. The lesion was biopsied and histopathological examination showed the classical features of sialadenosis. To our knowledge, this is the first case of sialadenosis affecting palatal minor salivary glands. It underlines that when sialadenosis is clinically suspected, clinicians could check also patients' oral cavity for minor salivary glands involvement, in order to potentially avoid invasive extra-oral procedures and to easily confirm diagnosis with an intra-oral biopsy.

The WHO has recently provided the most comprehensive global examination of cancer to date, through the publication of the World Cancer Report (WCR). According to IARC-WHO estimates, cancer rates are set to increase at an alarming rate, from 10 million new cases globally in 2000, to 15 million in 2020. However, the report states that we have the opportunity to stem the predicted sharp increase in new cancer cases by taking action now, especially through planning effective cancer control strategies, such as reducing tobacco consumption, suggesting healthy lifestyle and diet, and performing early detection through screening. Although cancer of the oral cavity is largely related to lifestyle and can be easily detected and diagnosed at early stages through a 5 min visual inspection of the oral mucosa, actual figures concerning its prevention and early detection are dismal. Most oral cancers are detected at a late stage, requiring complex, costly and often ineffective therapies. Similarly, current research, educational and financial resources are focused on procedures burdened by high cost, high morbidity and unacceptable high mortality. Here we suggest that it is time to change this common point of view towards this disease and to alter this trend, stressing that there is no other oncologic specialty in which the WCR preventive guidelines could be applied in such an easy and effective manner, as in the field of oral cancer.

The association of chronic inflammation with a variety of epithelial malignancies has been recognised for centuries. Well established examples include, among many others, oesophageal adenocarcinoma associated with chronic oesophagitis and bowel cancer associated with chronic inflammatory bowel diseases. By now no data, other than clinical observation, have been available in understanding the pathogenesis of these inflammation-related tumours. However, recent molecular studies on the relationship between solid malignancies and the surrounding stroma have given new insights. There is now enough evidence to accept that the chronic inflammatory process per se is able to provide a cytokine-based microenvironment which is able to influence cell survival, growth, proliferation, differentiation and movement, hence contributing to cancer initiation, progression, invasion and metastasis. Here it is discussed whether also oral lichen planus (OLP), being a chronic inflammatory autoimmune disease which has been clinically associated with development of oral squamous cell carcinoma, might be categorised among these disorders. With this aim, we critically reviewed and detailed the presence, in OLP subepithelial infiltrate, of inflammatory cells and cytokine networks that might act to promote squamous tumorigenesis.

Background: The recurrent chronic orofacial swelling caused by orofacial granulomatosis (OFG) can cause significant cosmetic and functional problems but can be prevented if the disease is diagnosed early and promptly treated. Although the enlargement of the lips is described to be the most common presenting complaint, the clinical onset of OFG may be characterized by minor associated mucosal and neurological manifestations, making early diagnosis very difficult or, sometimes, merely presumable., Patients and Methods: We retrospectively analyzed the clinical manifestations of 19 patients with OFG, who were examined at our institution between 1998 and 2002, in order to determine their initial manifestations and presenting symptoms., Results: A total of 10 patients showed classical recurrent enlargement of the lips (six lower; four upper) as presenting symptom. In the other nine patients, OFG onset was characterized by transient unilateral facial nerve palsy (two cases), intraoral manifestations (two cases), recurrent swelling of the periorbital area (two cases), of the chin (one case), of the zygomatic area (one case), and of the cheeks (one case)., Conclusion: Our data underlined that OFG onset could be frequently characterized by widely variable, multiform, and temporary clinical findings. Involvement of atypical sites of the orofacial region and presence of single minor manifestations may occur as presenting symptoms, often preceding the development of traditional clinical findings.

Aims: At present oral lichen planus (OLP) is classified among precancerous conditions but very few data are available in literature regarding prognosis of OLP-related cancers. The aim of this paper is to evaluate clinical long-term behaviour of OLP-related oral squamous cell carcinomas (OSCCs)., Methods: Clinical history and data from follow-up regarding 21 patients undergoing malignant transformation of OLP have been critically revised., Results: In a mean time of 2.6 years from diagnosis of OLP, patients developed OSCCs. Histopathologically, two carinomas showed a moderate degree of differentiation, while the others were well differentiated. Six (28.5%) were in situ OSCC, in eight (30%) was found a microinvasive pattern of infiltration, one was a stage II tumour and the remaining (6 cases) were stage I tumours. During follow up, four patients (19%) have developed another OSCC in a mean time of 11 months from the first occurrence. In two men (10% of cases), multiple OSCCs occurred and in five cases (24%) lymph nodal metastases were detected., Conclusions: Our study points out an alarming tendency in developing second primary metachronous tumours (33.3%) of the oral cavity and nodal metastases (23.8%), especially if we consider their early stages. Thus we always recommend a strict follow-up of OLP patients with clinical oral and neck examination every 2 months for 6-9 months since OSCC diagnosis is made and, after, three times a year.

Background: High-dose intravenous (i.v.) methylprednisolone has been used therapeutically in severe blistering diseases to avoid the complications and side-effects of long-term orally administered glucocorticoid therapy. The aim of the study is to evaluate the capacity of methylprednisolone i.v. 'pulse' therapy to induce remission in the treatment of severe oropharyngeal pemphigus., Methods: Twelve patients, all of whom had oropharyngeal severe pemphigus, were included in the analysis. There were eight women and four men whose ages ranged from 22 to 78 years (mean age: 50.75 years) with a disease duration of 1-3 months(mean duration: 55 days). In order to obtain a rapid clinical remission of extensive mucosal lesions, we performed 'pulse' therapy with intravenous methylprednisolone (30 mg/kg body weight to a maximum of 1 g per dose on each of 3-5 consecutive days)evaluating the clinical response and the short-term side-effects., Results: Our therapy was generally safe and well tolerated with a very low rate of side-effects. All patients responded to i.v. methyl-prednisolone with evidence of a decrease in signs and symptoms within l week of commencing treatment and in all cases remission was observed after the second or the third cycle of 'pulse'. The most common adverse events during treatment were flushing and hyperglycaemia; in a few cases we observed a metallic taste in the mouth, pruritus, headaches ranging from mild to moderate, palpitations, mood alterations, insomnia and fatigue., Conclusions: High-dose 'pulse' administration of glucocorticoids is a potentially effective therapy to be considered in the treatment of patients with severe oropharyngeal pemphigus. Similar patients treated with conventional oral administered doses of prednisone or deflazacort had protracted courses requiring months of glucocorticoid therapy with no long-term remissions. However, further well-designed, long-term comparative trials are required to confirm this.

Oropharyngeal cancer is estimated to be the ninth most common cancer worldwide. Its prognosis is largely dependent upon tumour-stage at the time of diagnosis. Stage I and II oropharyngeal cancers are characterized by a 5-year survival rate ranging from 70% to 90%, and the management of these early carcinomas is usually of short duration, easy and very cost-effective. On the other hand, the diagnostic evaluation, treatment and management of complications and recurrences of advanced stage oral tumours (stage III and IV) are often very long, complex and costly. They also have very poor prognosis with survival figures dropping to about 20%. Nowadays, most oropharyngeal cancers are detected at a late stage with an overall 5-year survival rate of around 45-50%, and with a conspicuous increase in treatment costs and a worsening of prognosis. Even if formal and comprehensive cost-effectiveness and cost-benefit analyses are not currently available in the oropharyngeal cancer literature, it seems clear that, in the care of these patients, the enormous consumption of resources is not associated with acceptable outcomes. New initiatives should be evaluated, planned and developed for the care of patients with oral and pharyngeal cancer. These strategies should be directed at prevention and early diagnosis in order to increase patient survival and quality of life and decrease the consumption of health care resources.

Background, Aims: Orofacial granulomatosis (OFG) is a descriptive term used for granulomatous disorders of the face and oral cavity that may occur for a variety of reasons, some of which result in significant morbidity and mortality. Although rarely, a granular enlargements of the gingiva may be the first clinical manifestation of OFG, preceding other local or systemic manifestations., Method: We will report a case of OFG that showed an atypical and monosymptomatic onset with a generalized hyperplastic gingivitis that preceded other facial and mucosal features by several weeks., Result: Considering the variable clinical onset of OFG and its apparent increase in incidence, we emphasize that in some cases, the periodontologist, as first consulted health care professional, plays an important role to detect this disorder. Early diagnosis of OFG is a crucial step to prevent and cure its unsightly sequelae and sometimes avoid progression of systemic potentially life-threatening OFG-related diseases., Conclusion: Thus, when none of the common causes of gingival enlargement can be detected, OFG diagnosis should be suspected.

In recent years, studies on the malignant potential of oral lichen planus (OLP) provided clinical evidence that patients affected by OLP have an increased risk to develop oral squamous cell carcinoma (OSCC); nevertheless, controversies still exist as to whether OLP has inherent predisposition to become malignant, or not. We believe extremely careful management of OLP patient is mandatory, and the aim of this paper is to illustrate our clinical guidelines in evaluating the possible risk of transformation in OLP lesions. Five-hundred and two patients (311 women and 191 men) affected by OLP regularly undergo follow-up examination in our Department. Patients' ages range from 18 to 83 years, with a mean of 55.4 years (57.5 for women and 53.9 for men); minimal follow-up period is 4 months, with a maximum of 12 years. In our group of OLP patients in the past 5 years we detected 24 carcinomas: excluding three cases in which diagnoses of OLP and OSCC were synchronous and three patients who had a history of tobacco use, thus possible malignant transformation of OLP would appear to be 3.7%. Clinical criteria used in our follow-up allowed us to detect 28.5% of tumours as in situ OSCC, 38% as microinvasive OSCC, 28.5% as stage I OSCC and 4.7% as stage II OSCC, with a remarkable improvement in prognosis compared to our previous study in which we adopted different criteria.

Oral lichen planus (OLP) is classified among precancerous conditions, as it is considered a generalized state associated with a significantly increased risk of cancer. The objective of this study was to discuss ultra-structural aspects of OLP that could play a role in enhancing metastatic potential, thus worsening the prognosis in oral squamous-cell carcinoma (OSCC). We report four cases of microinvasive OSCC which have occurred in OLP patients. All of them were stage I tumors, with a mean thickness of 1.75 mm. Recent studies indicate a tumor thickness over 4 mm as predictive of nodal metastases, but within 6 mo, our four patients with OSCC arising from OLP developed lymphnodal metastases. Our findings suggest that OLP-related OSCC may have a worse prognosis because of increased metastatic potential; obviously, further investigation is required, but this preliminary evidence emphasizes that extremely careful management of OLP patients is mandatory, and in cases of OSCC arising from OLP, a more radical treatment is probably required.

Background: The term latent coeliac disease (CD) is applied to patients who were previously shown to have a normal jejunal mucosa on a free diet. The aim of this study was to determine whether a high AGA value in the serum of patients with coeliac symptoms can also be regarded by itself, without typical mucosal atrophy, as a marker of latent CD, as some authors suggest in relatives of celiac patients., Methods: We observed 31 patients with suspected CD and pathological values of serum IgA ang IgG AGA. In all we performed intestinal biopsy, assayed antiendomisium antibodies (AEA) in serum, AGA IgA, IgG, and IgM in duodenal jejunal fluid and in some of the lymphocytcs CD3+ gamma/delta+ in the lamina propria of the intestinal mucosa., Results: In this study only pathological values of serum AGA without mucosa atrophy don't seem to be markers of latent CD, but an aspecific allergic response., Conclusions: As shown by other authors serum AEA, intestinal fluid AGA IgM and lamina propria lymphocytes CD3+ gamma/delta+ seem markers of latent CD.

Background: Hepatitis C virus (HCV) infection induces variable dermatologic manifestations., Objective: To determine whether differences exist in the clinical features and behavior of oral lichen planus (OLP) between HCV-positive (HCV+ve) and HCV-negative (HCV-ve) patients., Methods: Two hundred and sixty three patients (156 women and 107 men), with a mean age of 55.5 years, with OLP (76 HCV+ve and 187 HCV-ve) were clinically evaluated. Previously, all local factors that could modify the clinical characteristics were removed and were monitored carefully following morphology., Results: In both groups, the prevalent clinical form of OLP was the mixed form (33.1% in HCV-ve and 35.5% in HCV+ve patients), in which reticular-plaque lesions coexist with atrophic-erosive ones. The reticular form was more frequent in HCV+ve (25%) than in HCV-ve (18. 7%) patients, whereas plaque lesions were more prevalent in HCV-ve (15.5%) than in HCV+ve (5.2%) patients (P < 0.01, chi-squared test). There were no significant differences in the frequency of erosive (27.2% in HCV-ve and 27.6% in HCV+ve) and atrophic (5.3% in HCV-ve and 5.2% in HCV+ve) forms between the two groups., Conclusions: Our findings show that there were statistically significant differences between OLP-HCV-ve and OLP-HCV+ve groups for reticular and plaque clinical forms. These findings underline the importance of liver examination in all OLP patients, including cases with mild, asymptomatic keratotic forms of the disease.

Background: The association between diabetes mellitus and coeliac disease has been known for many years. In a random group of 175 insulin dependent diabetes mellitus patients of varying ages the following tests have been carried out: serum antigliadin antibodies (AGA) of IgA and IgG class, antireticulin antibodies (ARA) and antiendomisyum antibodies (AEA), both of IgA class., Materials and Methods: The patients, 85 males and 90 females, had ages ranging from 1 yr to 30 yrs (102 in paediatric age--mainly between 6 and 14 years--and 73 adults). Patients with pathological values for AEA and/or ARA underwent an intestinal biopsy., Results: Out of 175 patients studied, 21 had pathological values for AEA with or without pathological values for ARA and AGA, and 2 patients had only pathological values for ARA. 23 patients (21 with pathological values for AEA with or without ARA and AGA, 2 only for ARA ) underwent intestinal biopsy, all patients with pathological values for AEA had villous atrophy. The prevalence of coeliac disease among IDDM patients was 8.8% (95% CI 3.3 to 14.3) for the children and 16.4% (95% CI 7.9 to 24.9) for the adults. In patients with mucous atrophy, ARA, AGA IgA and IgG were pathological in 85%, 71% and 61% respectively. Symptoms and insulin requirements in all patients affected by coeliac disease before and after one year on a gluten free diet were also evaluated. The patients had clinical features with prevalently one or only few atypical symptoms which disappeared on a gluten free diet. Insulin requirements after one year on a gluten free diet appeared unchanged in coeliac patients., Conclusions: The need to screen all diabetic patients for coeliac disease is underlined.

A review of literature concerning the relationship between coeliac disease and lymphoma has been done. There is a general agreement on the greater risk for development of malignant lymphoma in coeliac patients than in general population. The traditional debate around the question of whether or not T cell lymphoma may be a cause or an effect of coeliac disease to be continued. The recently results are suggestive of a protective role for a gluten-free-diet against malignancy in coeliac disease and give further support for advising all patients to adhere to a strict gluten-free-diet for life.

Objective: The authors sought to evaluate how the services required by the Italian Psychiatric Reform of 1978 were implemented in Emilia-Romagna, a region of 4 million inhabitants in Northern Italy., Method: All psychiatric facilities were monitored from 1978 to 1994 to determine the number and rates of admissions, average duration of stay, average intake, and percent of beds occupied at inpatient facilities as well as the number of patients residing in former mental hospitals and the number and rates of first contacts with mental health community centers., Results: Three mental hospitals out of nine were closed during the period, and the number of patients who resided in mental hospitals declined from 4,798 to 655. By 1994, there were 145 community centers, 48 day treatment centers, 12 general hospital psychiatric wards, three university psychiatric clinics, seven private psychiatric clinics, 24 psychiatric residences, and 123 supervised apartments that were operating as alternatives to asylums. The overall rate of inpatient admissions remained stable, but compulsory admissions gradually decreased by 35% throughout the period. First contacts at outpatient centers increased by 17.9% from 1984 to 1991., Conclusions: The shift from a hospital-based to a community-based psychiatric system of care, as foreseen by the Italian psychiatric reform, seems feasible. Some general political, administrative, and social backup conditions appear crucial to ensure the good outcome of this process.
