It may affect any anatomical site in the mouth, but most commonly the tongue and the floor of the mouth. It usually arises from a pre-existing potentially malignant lesion, and occasionally de novo;but in either case from within a field of precancerized epithelium. The use of tobacco and betel quid, heavy drinking of alcoholic beverages and a diet low in fresh fruits and vegetables are well known risk factors for oral squamous cell carcinoma. Important risk factors related to the carcinoma itself that are associated with a poor prognosis include large size of the tumour at the time of diagnosis, the presence of metastases in regional lymphnodes, and a deep invasive front of the tumour. Squamous cell carcinoma is managed by surgery, radiation, and chemotherapy singularly or in combination;but regardless of the treatment modality, the five-year survival rate is poor at about 50%. This can be attributed to the fact that about two-thirds of persons with oral squamous cell carcinoma already have a large lesion at the time of diagnosis.展开更多

The following terms were used to locate articles: "oral'' or "enteral'' and "postoperative care'' or "post-surgical'' and "proteins' ' or "milk proteins' ' or "dietary proteins' ' or "dietary supplements' ' or "nutritional supplements' '. In databases that allowed added limitations, results were limited to clinical trials that studied humans, and publications between 1990 and 2014. Quality of collated studies was evaluated using a qualitative assessment tool and the collective results interpreted.RESULTS: Searches identified 629 papers of which, following review, 7 were deemed eligible for qualitative evaluation. Protein supplementation does not appear to affect mortality but does reduce weight loss, and improve nutritional status. Reduction in grip strength deterioration was observed in a majority of studies, and approximately half of the studies described reduced complication rates. No changes in duration of hospital stay or plasma protein levels were reported. There is evidence to suggest that protein supplementation should be routinely provided post-operatively to this population. However, despite comprehensive searches, clinical trials that varied only the amount of protein provided via oral nutritional supplements(discrete from other nutritionalcomponents) were not found. At present, there is some evidence to support routinely prescribed oral nutritional supplements that contain protein for gastrointestinal surgery patients in the immediate post-operative stage.CONCLUSION: The optimal level of protein supplementation required to maximise recovery in gastrointestinal surgery patients is effectively unknown, and may warrant further study.展开更多

The objectives of this study were to determine the socio-demographic status of consumers and describe the clinical characteristics of the oral lesions observed. <strong>Material and Method: </strong>It was a descriptive cross-sectional study lasting 12 months (January 2017 to January 2018), in the prefectures of Kankan and Siguiri as a framework. Individuals who use chewing tobacco and whose oral examination revealed oral lesions were included in this study. <strong>Results:</strong> The frequency of oral lesions induced by the consumption of chewing tobacco was 90%. Dental pain was the most cited reason for using CT by respondents, i.e., 25.41%. The most concerned age group was that of 50 - 64 years or 23.81 with a male predominance of 84.13% (n = 53). A number of 61 respondents came from rural areas. Farmers were the predominant socio-professional group, i.e., 63.49% (n = 40). In 60.32% (n = 38) of respondents, the duration of CT consumption was greater than 10 years. Black villous tongues followed by neoplastic ulcerations were the most common oral lesions with 32 (50.79%) and 14 (22.22%) cases, respectively. The site of the lesion was the tongue in 47 consumers (74.61%) and in the lower vestibule in 15 users (23.80%). Among the oral diseases, mylolysis was the most common, i.e., 95.24% (n = 60). In 82.54% of cases (n = 52), Simplified Oral Hygiene Index (SOHI) was low and in 12.70% (n = 8) of respondents, SOHI was good. <strong>Conclusion: </strong>Chewing tobacco predisposes to a high risk of damage to the oral cavity and the development of potentially malignant lesions. In addition, it exerts some detrimental effects on the teeth and adjacent structures.展开更多
