Study Design: A structured electronic search strategy identified studies that analyzed frequency, clinical, biological, demographic, biomarkers, and prognostic features of s-OSCC and OSCC-dn according to PRISMA guidelines in PubMed, Scopus, Cochrane Library, and Google Scholar, up to January 31, 2023. Inclusion criteria were original English, Spanish, Portuguese, French, Italian, and German cross-sectional, cohort, and case-control studies.

CREST syndrome diagnosed by oral lesions: A case report and review of the literature.

Background: Calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome is an acronym for the clinical features that are seen. Its etiology is unknown, affecting women three times more than men. CREST syndrome is often diagnosed by systemic symptoms.

Barriers to early diagnosis and management of oral cancer in Latin America and the Caribbean.

Objective: This study aimed to explore perceived barriers to early diagnosis and management of oral cancer, as well as potential pathways for improvement in Latin America and the Caribbean (LAC).

Methods: This cross-sectional study used a self-administered online questionnaire created via the Research Electronic Data Capture platform. The survey was distributed to health professionals trained in Oral Medicine, Oral Pathology, Oral and Maxillofacial Surgery, and Dentists with clinical and academic expertise in oral potentially malignant disorder (OPMD) and oral cancer.

Unusual clinical presentations of plasma cell mucositis involving oral mucosa: Presentation of 2 cases and review of the literature.

Objective: Plasma cell mucositis (PCM) is a non-neoplastic plasma cell disorder of the upper aerodigestive tract with a high impact on life quality. Less than 70 cases were reported in the literature. The objective of this study was to report 2 cases of PCM.

[Therapeutic alternatives for drug-associated maxillary osteonecrosis (MRONJ): reports of two clinical cases and review of the literature].

Introduction: Drug-associated Maxillary Osteonecrosis is one of the most relevant adverse effects in treatment with antiresorptive drugs such as bisphosphonates and denosumab. Oncological conditions such as multiple myeloma, breast cancer, prostate, and bone-metabolic disorders such as osteoporosis lead the indications for these antiresorptive therapies. Treatment is complex because the disease is often refractory.

Oral squamous cell carcinoma arising from chronic traumatic ulcers.

Background: A proportion of oral squamous cell carcinoma (OSCC) is preceded by oral potentially malignant disorders (OPMD), and the rest might not be associated with any well-established OPMD. Chronic traumatic ulcer (CTU) has been suggested as a lesion with potential for malignant transformation, but the evidence is inconclusive.

Objective: The aim of this study was to describe clinicopathological features of non-healing CTU (NHCTU) that later developed to OSCC.

Chronic mechanical irritation enhances the effect of tobacco and alcohol on the risk of oral squamous cell carcinoma: a case-control study in Argentina.

Objectives: Oral squamous cell carcinoma (OSCC) is a multifactorial disease. The individual effect of each risk factor for OSCC may be conditioned by the frequency of other factors. The objective of this study was to identify the association between chronic mechanical irritation (CMI) and OSCC and to analyse the influence of CMI on other important risk factors for OSCC.

Oral squamous cell carcinoma in coca chewers from a north region of Argentina: A case series and review of literature.

Chewing coca leaves is a habit still practiced in Bolivia, Peru and Argentina. There is scarce evidence in the relationship between this habit and development of oral squamous cell carcinoma (OSCC), some authors have found oral epithelial changes in coca chewers. This study aimed to present a case series of patients with a coca chewing habit that developed OSCC, in the absence of risk factors for oral cancer.

Non-innocent ligand flavone and curcumin inspired ruthenium photosensitizers for solar energy conversion.

A series of ruthenium photosensitizers incorporating a β-diketonate non-innocent ligand were synthesized, characterized, and implemented in dye-sensitized solar cells. Electrochemical studies exhibited well behaved reversible oxidations and reductions for all β-diketonate complexes. The acac- and Ph2acac- based photosensitizers possess limited delocalization across the ligand π*-manifold, which is significant for exhibition of respectable power conversion efficiencies in a dye-sensitized solar cell (DSC) device.
