Oral and maxillo‐facial manifestations of systemic diseases: An overview
Full text linkMany systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors present an overview on the most frequent clinical manifestations at the oral and maxillo-facial district of systemic disease
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Cheilitis and gingivitis as first signs of Crohn's disease in a pediatric patient
No full textOral manifestations of Crohn's disease include gingivitis, deep ulcerations, pseudopolyps, and labial or buccal swelling; these are uncommon in children and can precede or coincide intestinal inflammation lesions, leading frequently to a delayed diagnosis
Oral maxillary exostosis
Full text linkOral maxillary exostoses are proliferating bone lesions with an unknown etiology occurring on the cortical plates both in the maxilla and in the mandible of young individuals, showing a typical slow but continuous enlargement. No treatment is usually required unless they create esthetic or functional limitations during follow-up; the biopsy is needed only for doubtful lesions. Furthermore, it is mandatory to collect an accurate familiar history of patients affected by exostosis, especially when occurring with atypical clinical presentation, in order to exclude or prevent potentially associated systemic diseases
Malignant transformation of oral proliferative verrucous leukoplakia: a series of 48 patients with suggestions for management
No full textProliferative verrucous leukoplakia (PVL) is a rare and refractory form of oral mucosal leukoplakia of unknown origin, characterized by high rates of malignant transformation. Different diagnostic criteria, terminologies, and therapeutic approaches have been proposed since the first report in 1985. There remains no general agreement regarding the clinical and histological diagnosis, prevention, and correct management of this disease. This retrospective study investigated 48 patients affected by PVL showing at least one malignant transformation and followed up at 2-month intervals. Twenty-five were female (52.1%) and 23 (47.9%) were male; their median age was 67 years (range 40–93 years). Follow-up ranged from 18 to 240 months. Clinical examination included the use of Lugol's solution to prevent clinical underestimation of the margins and toluidine blue for suspicious areas. Surgical excision by scalpel was the preferred treatment for suspicious lesions, with only five carcinomas surgically removed by diode laser and two by CO2 laser. All specimens were accurately mapped after formalin fixation. Fifteen patients (31.3%; 10 female, five male) developed one oral carcinoma, while 33 (68.7%) developed two or more primary tumours (range 3–12). Only four patients (8.3%), who developed between 2 and 8 oral squamous cell carcinomas (OSCCs), died of tumour-related causes. The pre-surgical clinical workup, subsequent surgical treatment, and follow-up are key to success for patients affected by PVL with malignant transformation into stage 1 OSCC and/or verrucous carcinoma, leading to a high overall survival rate
Granular cell tumour of the tongue treated by radiofrequency ablation
No full textIl tumore a cellule granulari è una neoplasia piuttosto rare del cavo orale. Solitamente si presenta come lesione nodulare, sessile, asintomatica, a lenta crescita, rivestita da mucosa normocolorata a meno che non intervengano fenomeni di ulcerazione dovuta esclusivamente a trauma masticatorio, e con un caratteristico colorito giallastro che guida alla diagnosi differenziale pre-chirurgica. L’escissione deve essere eseguita in toto per ridurre il rischio di recidive dovuta ad incompleta enucleazione, anche mediante sistemi elettromedicali, come per esempio la radiofrequenza chirurgica utilizzata nel caso descritto, che rendono l’atto chirurgico più semplice per riduzione del sanguinamento intra-operatorio non alterando la precisione di escissione ed il campione chirurgico al fine del susseguente esame istologico, che è obbligatorio per la diagnosi finale.AIM: To report on a case of granular cell tumour occurring in the tongue surgically removed by surgical radiofrequency, with histological examination. MATERIAL OF STUDY: Discussion on the clinico-pathological characteristics of the granular cell tumour and the surgical treatment by surgical radiofrequency: the differential diagnosis is also discussed. RESULTS: Histological examination is mandatory for the final diagnosis. Surgical radiofrequency is an useful medical device to achieve good quality surgery with minimal post-operative course. DISCUSSION CONCLUSIONS: Although rare, granular cell tumour should be always considered in the differential diagnosis of nodular lesions of the oral mucosa above all when the tongue is involved and a yellow appearance is detectable. The surgery will be guided by the clinical diagnosis and accurately performed to prevent recurrence. A medical device promoting reduction of the intra-operative bleeding is suggestable for such surgical treatments. KEY WORDS: Granular cell tumour, surgical radiofrequency, neurogenic tumour
Medication-related osteonecrosis of the jaw: Surgical or non-surgical treatment?
No full textMedication-related osteonecrosis of the jaw (MRONJ) is a severe side effect of antiresorptive (bisphosphonates and denosumab) and anti-angiogenic therapy used in the management of oncologic and, less frequently, osteoporotic patients. While there is good international agreement on the diagnostic and staging criteria of MRONJ and the cessation of antiresorptive/anti-angiogenic treatments, the gold standard of treatment is still controversial, in particular between non-surgical and surgical approaches. The former usually includes antiseptic mouth rinse, cyclic antibiotic therapy, low-level laser therapy and periodic dental checks; the latter consists of surgical necrotic bone removal. The purpose of this retrospective study was to describe the therapeutic approaches and outcomes of 131 lesions from 106 MRONJ patients treated at the Policlinic of Bari. Non-surgical treatments were chosen for 24 lesions that occurred in 21 patients who, due to comorbidities and/or the impossibility of stopping oncologic therapies, could not undergo surgical treatment. As to the outcome, all the surgically treated lesions (107) showed complete healing, with the exception of 13.5% of the lesions, all of which were stage III, which did not completely heal but showed reduction to stage I. The 24 non-surgically treated lesions never completely healed and, rather, generally remained stable. Only two cases exhibited a reduction in staging. Based on our observations, MRONJ occurring both in neoplastic and non-neoplastic patients benefits more from a surgical treatment approach, whenever deemed possible, as non-surgical treatments do not seem to allow complete healing of the lesions
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Fine-needle aspiration in head and neck diagnosis.
No full textFine‐needle aspiration cytology (FNAC) is a simple and inexpensive widely used diagnostic technique for the presurgical pathologic diagnosis of head and neck proliferating lesions.1, 2 This Video S1 shows as examples two of the most common indications (a soft texture latero‐cervical/salivary swelling and a hard texture palatal swelling) (Figure 1) to the preoperative diagnosis by FNAC, the necessary equipment, and the technique. Although FNAC is a well‐established method advised by many physicians since is a safe procedure with minimal possible complications and can be also performed in an outpatient setting, an adequate training period is mandatory to achieve good results in terms of diagnostic accuracy
