A new oral lavage solution vs cathartics and enema method for preoperative colonic cleansing
Sulfate free-electrolyte lavage solution is a new osmotically balanced electrolyte gut lavage solution for colon surgery that has been formulated for improved taste and reduced water and electrolyte changes. Sixty patients were prospectively randomized to receive a 1-day preparation with sulfate free-electrolyte lavage solution or a 3-day preparation using a clear liquid diet, cathartics, and enemas. The patient groups were similar in age, race, male-female ratio, and the types of colonic resections performed. Colonic cleansing was better with sulfate free-electrolyte lavage solution (100% vs 63% ''good'' to ''excellent'' cleansing). Patient tolerance evaluated by a questionnaire showed more overall discomfort with sulfate free-electrolyte lavage solution but no difference between the preparations in individual symptoms of fullness, cramping, nausea, or vomiting. One patient developed a low level of serum potassium after a cathartic and enema preparation, while there were no complications with sulfate free-electrolyte lavage solution. Patient taste questionnaires showed a slight preference for sulfate free-electrolyte lavage solution (53%) over a polyethylene glycol electrolyte lavage solution (47%). This study confirms that sulfate free-electrolyte lavage solution is a safe and effective method of preoperative colonic cleansing

Focus on the cariogenic process: microbial and biochemical interactions with teeth and oral environment
This paper aims to describe the biochemical interactions between teeth and the oral environment that occur during the caries process, hence it covers all the steps related to physico-chemical reactions, including the most up-to-date theoretical basis in the clinical application for the prevention and treatment of caries. The terms 'demineralization' and 'remineralization' that characterise this process were analysed, as well as the role of the microbiota in its interaction with the hard surface of the teeth. The biochemical mechanisms that lead to the onset of carious lesions and those that occur during the healing and repair of such lesions are listed
Non-Hodgkin lymphoma affecting the tongue: Unusual intra-oral location
Introduction. The expression non Hodgkin lymphoma is used to cover a wide group of lymphoid neoplasias unrelated to Hodgkin's disease, due to the huge histological variety and the tendency to affect organs and tissues that does not physiologically contain lymphoid cells. The intraoral location is not frequent (3 - 5 percent of cases) and the initial manifestations of the disease rarely take place here. Case presentation. We describe the case of a 73 years old Italian caucasian male who came to our attention with a tongue lesion. The clinical manifestation was macroglossia and bleeding, probably deriving from the tongue-bite injuries. The patient had been complaining of dyspnea for 48 hours. Conclusion. A tongue affected by non-Hodgkin's lymphoma rarely occurs. In spite of this, this possibility should always be considered for the differential diagnosis of benign and malignant lesions affecting such area. A rapid diagnostic assessment, together with an adequate histopathologic verification, are indeed essential to improve the management and the prognosis of this disease. © 2011 Inchingolo et al; licensee BioMed Central Ltd
Analysis of Risk Factors of Oral Cancer and Periodontitis from a Sex- and Gender-Related Perspective: Gender Dentistry
Gender-specific medicine studies how sexual biology and gender-related cultural and behavioral differences may influence a person's health and considers the differences in clinical features, prevention, therapies, prognosis, and psycho-social aspects of diseases with different impacts on women and men. The present work summarizes the main differential impact each risk factor for oral cancer and periodontitis has according to biological sex- and gender-oriented differences. It resulted in differences in epidemiology and the weight of various healthy determinants that may influence the incidence and prognosis of oral cancer and periodontitis. It is desirable to change the methodology of scientific studies with a higher focus on the weight that sexual variables may have on the well-being or the probability of getting ill of each person, thus promoting the development and diffusion of personalized gender dentistry
Oral piercing and oral diseases: a short time retrospective study.
Body piercing indicates the puncturing of a part of the body in which jewelry may be worn. In recent years, oral piercing is increasingly popular especially among young people. Body piercing has to be considered as a surgical procedure to all intents and purposes and, as such, has to be performed only by qualified personnel able to assure high standards of professionalism in facilities subject to sanitary inspections. The aim of the present work is to verify what risks patients may be exposed to and what complications may occur after a healthcare professional performs oral piercing. Our retrospective study includes 108 patients (74 males and 34 females) aged between 14 and 39 years, who had oral piercing done 12±4 months earlier. All the patients underwent clinical examination to reveal the possible presence of late complications. After piercing, none of the 108 patients developed widespread complications. Although all patients said they had followed the piercers' instructions, 96% of them reported postoperative local complications such as bleeding within 12 hours of piercing (90%), perile-sional edema for 3±2 days after piercing surgery (80%), and persistent mucosal atrophy (70%). © Ivyspring International Publisher
Non-syndromic multiple supernumerary teeth in a family unit with a normal karyotype: Case report
Introduction. Hyperdontia is an odontostomatologic anomaly characterized by an excess in tooth number. It seems to occur more often in patients with hereditary factors concerning this anomaly: this case represents a rare form of hyperdontia, with bilateral multiple supernumerary teeth, with evident penetrance of the phenotype in the family unit engaged in the present study. The karyotype determination excludes a pathogenesis on chromosomal basis. Case report. A 30 years old patient came to our observation with five impactedteet h (1. 8, 2. 8, 3.8, 4.7 and 4.8), as well as with the presence of an impacted supernumerary tooth (distomolar 4. 9). The patient was suggested to allow us to perform a radiologic screening to his two sisters aged 17 and 13 years. The X-ray photography showedt hat the elder sister had nine impacted teeth; these were 1. 8 - 1.9 - 2.8 - 2.9 - 2.10 - 3.8 - 3.9 - 4.8 - 4.9; while the youngest sister had four impacted teeth, that is 1.8 - 1.9 - 2.8 - 2.9. Conclusions. The value of the present caser report can be used as a paradigm for the assessment of the hereditary factors predisposing the onset of hyperdontia, and for the consequent management by oral surgeon of family units in which the odontostomatologic anomaly was detected without any syndromicforms. © Ivyspring International Publisher
