A high viral load was strongly associated to the oral lesions occurrence independently of CD4+ cell count, and the most common oral lesion was Oral Candidiasis followed by Oral Hairy Leukoplakia, Oral Leukplakia and Melanic Hyperpigmentation.
Prevalence of oral soft tissue lesions in an elderly venezuelan population.
The findings observed in this population are important to be considered when clinically evaluating oral soft tissue in elderly and close follow up and systematic evaluation is required in thispopulation.

Assessment of cytokeratin 7/20 immunoprofile may facilitate the differential diagnosis of (a) primary malignant salivary gland tumors from metastatic tumors, (b) metastatic salivaries gland tumors, or (c) primary salivARY gland tumor tumors, especially mucoepidermoid carcinomas from squamous cell carcinomas, and (d) salvary duct carcinoma from other malignant Salivary glands.

Dental examination revealed markedly hypoplastic, yellowish-to-brownish enamel in all permanent teeth, malocclusion, and chronic periodontal disease, and the differential diagnosis and treatment of VDDRI are discussed.
Primary Sjögren syndrome in childhood: report of a case and review of the literature.
Neurofibromatosis type 1: a clinicopathological study of the orofacial manifestations in 6 pediatric patients.
The aim of this report was to elucidate the orofacial manifestations observed in 6 pediatric patients diagnosed with NF1, characterized by a variety of clinical manifestations, including multiple neurofibromas that are associated with a high risk of sarcomatous transformation.

Successful in vitro infection of PBMC with HCV infectious serum also resulted in an impairment of NK cytotoxicity, suggesting that altered NK function is associated withHCV infection and may be responsible, at least in part, for the chronicity of the infection.
Granulomatous foreign-body reaction involving oral and perioral tissues after injection of biomaterials: a series of 7 cases and review of the literature.
Detection of human papillomaviruses of high oncogenic potential in oral squamous cell carcinoma in a Venezuelan population.
A high prevalence of HPV infection of high oncogenic potential types in patients with SCC in the studied group was observed and differences could be influenced by nutritional, environmental and genetical factors in the population but further studies should be carried out to determine these aspects.
Immunohistochemical expression of angiogenesis-related markers in oral squamous cell carcinomas with multiple metastatic lymph nodes.
Angiogenesis is essential for tumor growth and metastasis; accordingly, the observed differences in the immunohistochemical expression of angiogenesis-related proteins in oral SCC with multiple lymph node involvement may provide an explanation for the increased metastatic potential of these tumors.
