Oral lichen planus is a chronic inflammatory disease of unknown etiology, characterized by recurrent lesions, presenting as reticular lesions, sometimes accompanied by atrophic, erosive, and/or ulcerative areas. Despite being one of the most common conditions affecting the oral mucosa, oral lichen planus remains an ailment with undefined etiology and unclear pathogenesis, imprecise management, and uncertain premalignant potential.
A narrative literature review study was conducted. A bibliographic search was carried out in databases such as PubMed, Hinari, SpringerLink, the National Center of Biotechnology Information, and Medline. Articles published from 1990 to 2023 were selected using various combinations of keywords: “oral lichen planus,” and “epidemiology,” “etiology,” “pathogenesis,” “symptoms,” “management,” “histopathology,” and “malignant transformation.” After processing the data from these databases, 475 full articles were found. The final bibliography comprised 50 relevant sources, considered representative of the materials published on the topic of this synthesis article.
Oral lichen planus is an inflammatory condition associated with T-cell-mediated immune dysfunction. Triggers include autoimmune responses to local antigens, microorganisms, and stress. The disease results from a complex interplay of host factors, lifestyle, and environmental factors leading to T-cell-mediated immune dysregulation. Diagnosis of oral lichen planus is based on clinical features (multiple, bilateral, symmetrically distributed lesions, occurring most commonly on the buccal mucosa, dorsal tongue surface, and gingiva), histopathological findings (predominantly lymphocytic band-like infiltrate in the lamina propria, presence of apoptotic cells in the basal cell layer, absence of epithelial dysplasia), and immune-related changes (deposition of fibrinogen along the basement membrane zone, presence of granular fluorescent deposits containing IgA, IgG, and IgM in colloid bodies).
Oral lichen planus is a chronic inflammatory condition mediated by T-cells in response to various extrinsic antigens, modified autoantigens, or superantigens, with periods of remission and relapse and the potential for malignant transformation. The etiology and pathogenesis of this condition are complex, diagnosis relies on clinical features, histopathological findings, and immunological data, patient treatment is symptomatic, and the potential for malignant transformation varies. Nevertheless, prospective studies with large sample sizes, adequate treatment duration, and long-term follow-up are needed.
Benign prostatic hyperplasia and chronic prostatitis are the most common conditions in men, the frequency of which varies with age. Chronic prostatitis (infectious or inflammatory) has a frequency of 8-35% in patients aged 20-50 years, reaching a maximum of 60-70% in those aged over 50 years.
Materials for the study served the medical literature regarding benign prostatic hyperplasia and chronic inflammation, published in the local and international scientific journals. Scientific databases like Cochrane Library, Medline, Scopus, Medicus, NCBI, PubMed, Google Scholar were used to find the necessary articles. Research methods – analysis, synthesis, systematization, and description.
After analyzing the available data, a review of the literature was conducted which highlighted both the strong and weak points of the historical medical approaches to addressing benign prostatic hyperplasia, as well as the ontogenetics and anatomical characteristics of the prostate gland. This included examining the incidence rates, concepts of causation and development, principles of diagnosis and classification of benign prostatic hyperplasia. The review also revealed the pros and cons of using mini-invasive treatment strategies versus traditional transvesical approaches in treating this condition, as well as the ongoing and significant socioeconomic impact in underdeveloped countries.
There remains the issue of reducing intra- and post-operative complications after benign prostatic hyperplasia surgery, especially a voluminous one, which imposes itself as a very critical problem in the development of an effective treatment strategy. For the first time, a problem was described by assessing the particularities of some biochemical criteria at local surgical site and in blood serum, histological - at the level of nodular prostatic hyperplasia and at the border of the surgical site. This requires a complex correlational study to assess the biochemical, histological and immunohistochemical parameters, including the evaluation of the associations or coexistence of benign prostatic hyperplasia and chronic prostatitis.
