AIM: Warthin's tumor (WT) is the second commonest parotid gland neoplasm after pleomorphic adenoma (PA). It mainly arises from the lower pole of the superficial parotid lobe (i.e., tail of gland), a site with the greatest distribution of intra-parotid lymph nodes, and its definitive etiopathogenesis is still unclear. The aim of this study was to support the strict topic and etiologic link hypothesised between this tumor and the intraparotid lymph nodes, as being massively present in the tail, by assessing the WT distribution within the parotid gland. METHODS: Seventy-one WTs excised from 64 patients were compared retrospectively with 134 PAs from 133 patients, as controls. In all sample, staging of parotid gland tumors was defined by sonography and magnetic resonance imaging. Furthermore, tumor localization, size, bilaterality and multifocality were assessed according to radiological, intraoperative and histopathological findings. RESULTS: WTs were mainly detected in the tail (73%), less in the superficial lobe (23%) and the deep one (4%). WT presented with bilateral and synchronous lesions in 10% of cases vs. 0.75% of controls. CONCLUSION: Since the tail has been well known to present the greatest distribution of intra-parotid lymph nodes, our clinical findings on WT parotid localization could suggest the possible origin of this tumor from epithelial salivary gland ductal inclusions, as being likely entrapped during embryogenesis within the intra-parotid lymph nodes, and could support the hypothesis of a heterotopy in the pathogenesis of WT. However, this suggestive hypothesis based only on clinical and "topographic" data should be confirmed by histopathological studies about the presence of the salivary ductal elements trapped within the intra-parotid lymph nodes.

Purpose: To investigate the plaque inhibiting effects of two commercially available mouthrinses containing essential oils (EO). Both products contained the same concentration of EO, but one of them did not contain ethanol. Methods: The study was an observer-masked, randomized, 4 × 4 Latin square cross-over design, balanced for carryover effects, involving 12 participants in a 4-day plaque regrowth model. A 0.12% chlorhexidine (CHX) rinse and a saline solution served as positive and negative controls, respectively. On Day 1, subjects received professional prophylaxis, suspended oral hygiene measures, and commenced rinsing with their allocated rinses. On Day 5, subjects were scored for disclosed plaque. Results: Differences among treatments were highly significant (P< 0.0001), with greater plaque inhibition by CHX compared to EO rinse containing ethanol (P= 0.012), which, in turn, was significantly more effective than the rinse without ethanol and the saline (P< 0.001). The reduction in plaque regrowth seen with the EO rinse without ethanol was quite similar to that elicited by saline (P> 0.05). CLINICAL SIGNIFICANCE: The ethanol-free essential oil mouthrinse did not show anti-plaque efficacy in the absence of toothbrushing.

Dysphagia, defined as a difficulty in swallowing of fluids and/or solid foods, is one of the most frequent symptoms of esophageal, gastrointestinal, ear, nose and throat diseases. As such, it poses a diagnostic challenge and an interdisciplinary clinical problem. Of particular importance in diagnosis is to distinguish between esophageal and oropharyngeal dysphagia. Oropharyn-geal dysphagia is often associated with neuromuscular disorders and is treated with rehabilitative protocols, while esophageal dysphagia may be due to anatomical alterations and esophageal motility difficulties. While the former can be adequately treated with endoscopic or surgical therapy, the latter are currently treated only pharmacologically. Interestingly, dysphagia may present as the initial symptom of a wide spectrum of oral conditions, including traumatic ulcerations, neuromuscular diseases, systemic and local immuno-mediated or infectious lesions, malignant neoplastic diseases or mucositis following chemo-radiotherapy for head and neck cancers: in these cases it is called oral dysphagia. Dysphagia, with or without evident oral lesions, suggests the presence of an oropharyngeal disease and requires adequate diagnostic-therapeutic management. This paper describes the major oral and systemic diseases that may manifest themselves with oral manifestations inducing dysphagia. Clinical management guidelines in dysphagia triggered by neuromyogenic pathogenesis are discussed.

Intravenous bisphosphonates (BP) play a key role in the treatment of bone metastases. As a long-term side effects BP, a form of avascular osteonecrosis of the jaw has been reported. Although, invasive oral local procedures are often present in clinical history of patients suffering from bisphosphonates-related osteonecrosis of the jaws (BRONJ), about up to 50% of BRONJ are spontaneous. We report a case of a 68-year-old female with a spontaneous wide bone sequestration of the left mandibular body onset after infusion of zoledronic acid for 18 cycles for osseous metastasis due to metastatic anaplastic thyroidal carcinoma. Surprisingly the clinical aspects of the patient initially reminded us of the famous pathology described in 1899 called phossy jaw. This case is remarkable not only for the spontaneity of the osteonecrosis, but, above all, for the clinical similarity with cases of phossy jaw, described for the first time in the literature, thereby suggesting a potential common pathogenesis.

Introduction: Contrary to early beliefs, celiac disease (CD) is relatively common; however, it still remains underdiagnosed since most cases are atypical, with few or no gastrointestinal symptoms and predominance of extraintestinal manifestations. As a consequence, the diagnosis of the disorder often requires a multidisciplinary approach. Also some oral ailments have been described in celiac patients. In this study, we review the papers that have reported oral manifestations in subjects with CD. Methods: A comprehensive literature search was conducted in Medline and Embase databases using appropriate key words. Additional papers were selected by cross-referencing from the retrieved articles. Results: Dental enamel defects are the oral lesions most closely related to CD. There are conflicting data on the association between CD and recurrent aphthous stomatitis. A correlation of CD with atrophic glossitis has been reported, although robust evidence in support of it is lacking. Patients with CD have caries indexes seemingly lower than healthy individuals, but they may experience delay in tooth eruption. Occurrence of other oral mucosal lesions in CD subjects is likely occasional. Conclusions: Patients with systematic dental enamel defects should be screened for CD even in the absence of gastrointestinal symptoms. CD screening tests for patients with oral aphthae or idiopathic atrophic glossitis should be selectively considered during a medical evaluation that focuses on all aspects of the patient’s status.

This retrospective study investigated, in two cohorts of subjects living in Southern Italy and awaiting treatment for oral squamous cell carcinoma (OSCC), the variables related to diagnostic delay ascribable to the patient, with particular reference to the cognitive and psychological ones. A total of 156 patients with OSCC (mean age: 62 years, M/F: 2.39∶1) were recruited at the Universities of Palermo and Naples. Risk factors related to patient delay included: sociodemographic, health-related, cognitive and psychological variables. The analysis was conducted by considering two different delay ranges: dichotomous (≤1 month vs. >1 month) and polytomous (3 months) delay. Data were investigated by univariate and multivariate analyses and a P value ≤0.05 was considered statistically significant. For both delay measurements, the most relevant variables were: 'Personal experience of cancer' (dichotomous delay: P=0.05, odds ratio (OR)=0.33, 95% confidence interval (CI)=0.11-0.99; polytomous delay: P=0.006, Chi-square=10.224) and 'Unawareness' (dichotomous delay: P

Oral mucositis (OM) is a very frequent and potentially severe complication experienced by patients receiving chemotherapy and/or radiotherapy, which often leads to significant morbidity and mortality, and decreased quality of life, and is very costly. Despite its severity and prevalence, there is no standard recognised management today. The aim of this open clinical trial is to evaluate the efficacy and compliance of a new spray compound containing sodium hyaluronate (SH) and a pool of collagen precursor amino acids (AAs) combined with sodium hyaluronate (SH) to manage radio/chemotherapy-induced OM. Twenty-seven consecutive patients with OM were treated according to the manufacturer's instructions. At time TO (baseline — before intervention), we evaluated the following parameters: (i) pain score (by linear visual analogue scale; 0–100) and (ii) severity of OM scored according to WHO Mucositis scale. The treatment efficacy was evaluated on i) pain score, ii) clinical resolution index (CRI) and iii) patient compliance at times T01 (after 2 hours), T1 (after 24 hours), T2 (after 72 hours), T3 (after 7 days) and T4 (after 14 days). Results showed that painful symptoms were significantly reduced after only 2 hours of spray administration compared with baseline measurements ( p

Objectives: Self-injury (SI) is defined as a behavioral disturbance consisting of a deliberate harm to one’s own body without suicidal intent, it is not uncommon and ranges in severity from simple nail-biting to more extreme forms of self-mutilation. The head neck region may be the target of such lesions. SI is associated with several medical conditions, of which it can represent the first clinical sign. Aim of this paper is to describe a series of oral SI, giving special emphasis to the clinical findings, etiology and the management of lesions. Material and Methods: A total of 19 patients with oral SI were prospectively examined; attention was paid to the occurrence and characterization of oral lesions. The management of the lesion also varied depending on the patient medical history, on the etiology of the psychiatric behavior, and on the severity, frequency, and method of inflicting injury. Periodic examinations were performed (after two weeks, three months and six months) and registered. Results: All the patients healed gradually and healing was conditioned by the disease underlying. The treatment consisted of behavior modification in 11 cases, pharmacological treatment in 11 cases, psychotherapy in 2 cases, mouth guard in 9 cases, surgery in 2 cases, extractions in 1 case. Conclusions: Oral SI are uncommon in the clinical practice. They may be associated with a known disease or may be the consequence of this, but often they may be the first sign of a psychiatric disorder. Key words:Oral self-mutilation, self-inflicted lesions, self-injurious behavior, ulcers, Obsessive-Compulsive Disorder, mental retardation.

Sodium hyaluronate has been widely used in order to promote wound healing in oral cavity for its anti-inflammatory effects. Aim of this clinical trial was to evaluate the efficacy of aminoacids added to topical sodium hyaluronate, in minor oral surgery. After surgery by means of Quantic molecular resonance scalpel, in 27 patients a gel with sodium hyaluronate has been applied directly on the surgical wound, in order to favorite healing by secondary intention. Furthermore, gel has been applied 3-4times/day, after meals and oral hygiene. Hemostatic effect, edema and pain symptoms by VAS (Visual Analogue Scale;0-100), and clinical healing (full, partial, absent) have been evaluated at T#1(2hrs after surgery), T#2(after 24hrs), T#3(after 72hrs), T#4(after 7days) and T#5(after 14days). Regarding pain symptom, mean values registered were at T#0 6.7(± 20 DS;range: 0-60), at T#1 12.2(± 25,4 DS,range: 0-70), at T#2 4.4(± 7.3 DS,range: 0-20), at T#3 1.1(± 4,4 DS;range 0-10), while at T#4 and T#5 no patient complained pain. Evaluation of the intra-group symptom score at T#0, T#1, T#2 and T#3 showed no statistically significant differences in T#1 vs T#0(p = 0.5930,z = -0.535), T#2 vs T#1(p = 0.2850,z = -1.069) and T#3 vs T#2(p = 0.1088,z = -1.604), revealing a good early performance. In all patients have been found to complete clinical resolution of the surgical wound within 2 weeks after surgery. Only one slight bleeding at T#1 was observed, post-operative edema until T#3 was never present. In historical control1(cold scalpel), regarding about pain evaluation, mean values were in general worst [at T#0 was 20(±17,97), at T#1 15,0(±14,4) and at T#4 5,8(±9,5)]. In conclusion, aminoacids combined to sodium hyaluronate application seems to be advantageous in oral surgery, due to its hemostatic effect, reduction of pain symptoms, simple application, absence of infectious complications, and rapid healing of surgical wounds.
