Introduction: Noma is an opportunistic polymicrobial infection that cause necrosis of the mouth and face, with high morbidity and mortality, predominantly affecting malnourished children and persons with debilitating diseases. Cases of noma-like disease in adults, although rare, have been increasingly reported in HIV/AIDS patients particularly in developing countries but also in more developed countries., Methodology: A systematic review of the literature to assess the occurrence and clinical impact of noma and noma-like disease in HIV/AIDS patients was performed on PubMed, Virtual Health Library, Cochrane Library and Google Scholar using the keywords "HIV"[ All Fields] AND "Noma"[All Fields] in December 2016 (years includead for the search: 1985 to 2016)., Results: Twenty-four published studies were identified that document the occurrence of noma or noma-like disease in a total of 133 HIV/AIDS children and adult patients in the last 22 years. Although HIV infection is not the principal risk factor for noma, in some regions may play a substantial role in its pathogenesis. The mortality rate for noma-like disease in HIV/AIDS patients was 54.3%, compared to the 15% mortality rate of treated noma patients without HIV/AIDS. Most of the cases have never been on antiretroviral therapy, and their HIV infection was discovered because of the noma-like disease., Conclusions: The syndemic interaction between HIV/AIDS and noma-like disease adversely impacts the severity of the disease and the mortality rate. Noma-like disease, although not yet considered a specific or frequent disease associated with HIV infection, should be considered as an opportunistic infection for AIDS.

Introduction and Objectives: There are few reports focused on neoplasms in the submandibular gland because they are uncommon and are frequently grouped with the other salivary glands tumours. In the classical studies, the proportion of malignancy reported in these cases is around 50%., Objectives: Determining the proportion of malignancy, the most frequent histological types, the gender distribution and average age at diagnosis in patients with submandibular gland neoplasms who were treated in our hospital from 2000 year to 2010., Methods: A retrospective review of our department database of the patients who underwent surgery for submandibular gland neoplasm in a ten-year period was performed., Results: Twenty-two patient records were included, in which 19 (86%) patients presented benign disease and 3 were of a malignant type (adenocarcinoma, well-differentiated epidermoid carcinoma, follicular lymphoma). Two of the 3 cases of malignant neoplasms were in men., Conclusions: A greater proportion of benign neoplasm was found in submandibular tumours. The most frequent benign tumour is the pleomorphic adenoma. Women are more commonly affected (76%). Benign tumours appear in younger patients than do malignant ones., (Copyright © 2011 Elsevier España, S.L. All rights reserved.)
