Review
Pyoderma gangrenosum (PG) is a distinctive ulcerative skin disorder of unknown etiology, associated with an underlying systemic disease in up to 70% of cases. The condition is characterized by the appearance of one or more necrotic ulcers with a ragged undermined violaceous border and surrounding erythema. Lesions are often initiated by minor trauma. The condition can affect any anatomical site, however the head and neck are rarely involved. Although the oral cavity is subject to recurrent minor trauma through everyday activities such as mastication and oral hygiene, as well as during dental treatment, oral lesions appear to be extremely rare. In an effort to provide a detailed explanation of the oral manifestations of PG, a systematic search was conducted using medical databases. A total of 20 cases of PG with oral involvement were reported in the English and French literature. The objectives of this article are to present the pertinent diagnostic criteria and to discuss the differential diagnosis and therapeutic modalities.

BACKGROUND
Oral mucosa is encountered by various lesions and normal variants. Some are not to be worried about, whereas others may be of significance. Knowing the prevalence of oral mucosal lesions in a particular region helps better evaluate, diagnose, and, thus, manage these lesions.
OBJECTIVES
To assess the prevalence and distribution of oral mucosal lesions and normal variants among various age groups, genders, and sites of the orofacial region.
METHODS
This cross-sectional study was conducted in the Department of Oral Medicine and Radiology, KIST Medical College and Teaching Hospital from January 2021 to March 2021. Three different proformas were designed according to age, gender, and location of lesions for entry as per the WHO's guide. The obtained data were entered into a Microsoft Excel sheet for frequency analysis by SPSS, and the results were tabulated.
RESULTS
Among the records of 16572 (9703 (58.55%) males and 6869 (41.44%) females) OPD patients, 3495 (21.08%) (1934 (55.33%) males and 1561 (44.66%) females) had OMLs and 2314 (13.96%) (1626 (70.26%) males and 688 (29.73%) females) had normal mucosal variants. The most commonly seen OML categories were tobacco-associated lesions, i.e., 2056 (34.07%), tongue lesions, i.e., 1598 (26.48%), oral potentially malignant disorders, i.e., 815 (13.50%), ulcers i.e., 728 (12.06%), and infectious lesions, i.e., 256 (4.24%).
CONCLUSION
The Nepalese population has a wide range of oral mucosal lesions and normal variants, and this study has attempted to have baseline data for the same. The most common OML was smoker's melanosis.

Meta-Analysis Review
BACKGROUND
Oral erythroplakia has been classically considered as the potentially malignant disorder with the highest rate of malignant development into squamous cell carcinoma. This critical systematic review and meta-analysis aim to estimate the malignant development rate of oral erythroplakia and identify the associated risk factors.
METHODS
We performed a bibliographic search in PubMed, Scopus, Web of Science, Embase, and LILACS, with keywords "erythroplakia," "erythroplasia," "malignant transformation," "malignant development," "malignization," "carcinogenesis," "oral cancer," "oral squamous cell carcinoma," "mouth neoplasm," and "prognosis." Meta-analysis was conducted using a random-effects model.
RESULTS
Ten observational studies with 441 patients met the inclusion criteria, whose mean malignant development rate was 12.7% and with a mean follow-up period of patients of 6.66 years. In the initial biopsy, 42.8% of oral erythroplakia were already squamous cell carcinoma. The buccal mucosa was the most frequent location of oral erythroplakia, but the floor of the mouth was the most common site of malignant development. All patients who underwent malignant development showed epithelial dysplasia on the initial diagnostic biopsy.
CONCLUSION
Overall malignant development rate of OE in the meta-analysis was 19.9%. We could not associate any specific clinicopathological feature with the malignant development. The presence of epithelial dysplasia in the initial biopsy remains the worst prognostic factor. Further observational studies on OE are needed, with well-established diagnostic criteria and good clinical follow-up, in order to identify the true risk of malignant development of oral erythroplakia and the related risk factors.

Ulcers of the oral cavity, esophagus, and gastric compartments of South American camelids are uncommon. Multifocal-to-coalescing ulcers were identified in the oral cavity, esophagus, and/or gastric compartments of 5 alpacas submitted for postmortem examination. was isolated from the lesions in all alpacas, in combination with other aerobic and anaerobic bacteria. In 4 of these cases, -associated lesions were considered secondary to neoplasia or other chronic debilitating conditions; in 1 case, the alimentary ulcers were considered the most significant autopsy finding. It is not known if this agent acted as a primary or opportunistic agent in mucosal membranes previously damaged by a traumatic event, chemical insult, immunodeficiency, or any other debilitating condition of the host.

Review
Oral ulcers affect oral and systemic health and have high prevalence in the population. There are significant individual differences in the etiology and extent of the disease among patients. In the treatment of oral ulcers, nanofiber films can control the drug-release rate and enable long-term local administration. Compared to other drug-delivery methods, nanofiber films avoid the disadvantages of frequent administration and certain side effects. Electrospinning is a simple and effective method for preparing nanofiber films. Currently, electrospinning technology has made significant breakthroughs in energy-saving and large-scale production. This paper summarizes the polymers that enable oral mucosal adhesion and the active pharmaceutical ingredients used for oral ulcers. Moreover, the therapeutic effects of currently available electrospun nanofiber films on oral ulcers in animal experiments and clinical trials are investigated. In addition, solvent casting and cross-linking methods can be used in conjunction with electrospinning techniques. Based on the literature, more administration systems with different polymers and loading components can be inspired. These administration systems are expected to have synergistic effects and achieve better therapeutic effects. This not only provides new possibilities for drug-loaded nanofibers but also brings new hope for the treatment of oral ulcers.

Review
Oral ulcers are the most common mucosal sign in juvenile-onset systemic lupus erythematosus (JSLE). The ulcers are one of the key clinical features; however, the terminology of oral ulcers, especially in JSLE patients, is often vague and ill-defined. In fact, there are several clinical manifestations of oral ulcers in JSLE, and some lesions occur when the disease is active, indicating that early management of the disease should be started. Oral ulcers are classified as lupus erythematosus (LE) specific, where the lesional biopsy shows a unique pattern of mucosal change in LE, and LE nonspecific, where the ulcers and their histopathological findings can be found in other oral diseases. Here, the clinical manifestations, diagnosis and management of oral ulcers in JSLE patients are reviewed.

Review
COVID-19 is a new disease that presents mainly with respiratory symptoms. However, it can present with a multitude of signs and symptoms that affect various body systems and several oral manifestations have also been reported. We carried out a systematic review to explore the types of oral mucosal lesions that have been reported in the COVID-19-related literature up to 25 March 2021. A structured electronic database search using Medline, Embase, and CINAHL, as well as a grey literature search using Google Scholar, revealed a total of 322 studies. After the removal of duplicates and completion of the primary and secondary filtering processes, 12 studies were included for final appraisal. In patients with COVID-19 infection, we identified several different types of oral mucosal lesions at various locations within the oral cavity. Most of the studies appraised had a high risk of bias according to the Joanna Briggs Institute checklist. The current published literature does not allow differentiation as to whether the oral lesions were caused by the viral infection itself, or were related to oral manifestations secondary to existing comorbidities or the treatment instigated to combat the disease. It is important for healthcare professionals to be aware of the possible link between COVID-19 and oral mucosal lesions, and we hereby discuss our findings.

OBJECTIVES
To investigate the association between hospitalization for COVID-19 and oral changes, and to evaluate whether oral changes can indicate a higher risk of disease progression to death.
MATERIALS AND METHODS
This case-control study analyzed patients hospitalized (university hospital), including those in intensive care unit and clinical wards. The study group comprised 69 COVID-19 positive patients (PCR-test), while the control group included 43 COVID-19 negative patients. A dentist performed oral evaluations, and salivary samples were collected for calcium, phosphatase, and pH analysis. Sociodemographic data, hospitalization information, and hematological test results were collected from electronic-medical records. The presence of oral changes was assessed using chi-square tests, and the predicted risk of death was analyzed using binary logistic regression.
RESULTS
COVID-19 positive patients had a significantly higher prevalence of oral changes compared to COVID-19 negative patients. The presence of any oral changes in COVID-19 positive patients indicated a 13-fold higher risk of mortality. "Bleeding ulcers," "pressure ulcers," and "angular cheilitis" were significantly associated with hospitalization for COVID-19.
CONCLUSION
There may be an association between hospitalization for COVID-19 and the development of oral changes, including bleeding ulcers, pressure ulcers. and angular cheilitis. These oral changes may serve as potential indicator for disease progression an increased risk of death.
CLINICAL RELEVANCE
COVID-19 hospitalized patients have a higher prevalence of oral changes, which indicate an increased risk of mortality. Oral medicine staff should be included in multidisciplinary teams to detect and treat these oral changes promptly.

BACKGROUND
Clinically, a large part of inflammatory bowel disease (IBD) patients is complicated by oral lesions. Although previous studies proved oral microbial dysbiosis in IBD patients, the bacterial community in the gastrointestinal (GI) tract of those IBD patients combined with oral ulcers has not been profiled yet.
METHODS
In this study, we enrolled four groups of subjects, including healthy controls (CON), oral ulcer patients (OU), and ulcerative colitis patients with (UC_OU) and without (UC) oral ulcers. Bio-samples from three GI niches containing salivary, buccal, and fecal samples, were collected for 16S rRNA V3-V4 region sequencing. Bacterial abundance and related bio-functions were compared, and data showed that the fecal microbiota was more potent than salivary and buccal microbes in shaping the host immune system. ~ 22 UC and 10 UC_OU 5-aminosalicylate (5-ASA) routine treated patients were followed-up for six months; according to their treatment response (a decrease in the endoscopic Mayo score), they were further sub-grouped as responding and non-responding patients.
RESULTS
We found those UC patients complicated with oral ulcers presented weaker treatment response, and three oral bacterial genera, i.e., Fusobacterium, Oribacterium, and Campylobacter, might be connected with treatment responding. Additionally, the salivary microbiome could be an indicator of treatment responding in 5-ASA routine treatment rather than buccal or fecal ones.
CONCLUSIONS
The fecal microbiota had a strong effect on the host's immune indices, while the oral bacterial microbiota could help stratification for ulcerative colitis patients with oral ulcers. Additionally, the oral microbiota had the potential role in reflecting the treatment response of UC patients. Three oral bacteria genera (Fusobacterium, Oribacterium, and Campylobacter) might be involved in UC patients with oral ulcers lacking treatment responses, and monitoring oral microbiota may be meaningful in assessing the therapeutic response in UC patients.
