Review
Artificial intelligence (AI) has been cited as being helpful in the diagnosis of diseases, the prediction of prognoses, and the development of patient-specific therapeutic strategies. AI can help dentists, in particular, when they need to make important judgments quickly. It can eliminate human mistakes in making decisions, resulting in superior and consistent medical treatment while lowering the workload on dentists. The existing studies relevant to the study and application of AI in the diagnosis of various forms of mouth ulcers are reviewed in this work. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards were followed in the preparation of the review. There were no rule violations, with the significant exception of the use of a better search method that led to more accurate findings. Using search terms mainly such as AI, oral health, oral ulcers, oral herpes simplex, oral lichen planus, pemphigus vulgaris, recurrent aphthous ulcer (RAU), oral cancer, premalignant and malignant disorders, etc., a comprehensive search was carried out in the reliable sources of literature, namely PubMed, Scopus, Embase, Web of Science, Ovid, Global Health, and PsycINFO. For all papers, exhaustive searches were done using inclusion criteria as well as exclusion criteria between June 28, 2018, and June 28, 2023. An AI framework for the automatic categorization of oral ulcers from oral clinical photographs was developed by the authors, and it performed satisfactorily. The newly designed AI model works better than the current convolutional neural network image categorization techniques and shows a fair level of precision in the classification of oral ulcers. However, despite being useful for identifying oral ulcers, the suggested technique needs a broader set of data for validation and training purposes before being used in clinical settings. Automated OCSCC identification using a deep learning-based technique is a quick, harmless, affordable, and practical approach to evaluating the effectiveness of cancer treatment. The categorization and identification of RAU lesions through the use of non-intrusive oral pictures using the previously developed ResNet50 and YOLOV algorithms demonstrated better accuracy as well as adequate potential for the future, which could be helpful in clinical practice. Moreover, the most reliable projections for the likelihood of the presence or absence of RAU were made by the optimized neural network. The authors also discovered variables associated with RAU that might be used as input information to build artificial neural networks that anticipate RAU.

Comparative Study Meta-Analysis Review
BACKGROUND
The assumption that adjuvant modalities have added value to oral glucocorticoids in the treatment of pemphigus is intuitively sound but has not been conclusively proven.
OBJECTIVE
We sought to compare the efficacy and safety of oral glucocorticoid treatment with or without adjuvants for pemphigus vulgaris and pemphigus foliaceus.
METHODS
We performed a systematic review and meta-analysis of randomized controlled trials. The primary outcome was remission. Secondary outcomes were disease control, time to disease control, relapse, time to relapse, cumulative glucocorticoid dose, withdrawal because of adverse events, and all-cause death. Trials were pooled irrespective of adjuvant type evaluated.
RESULTS
Ten trials (559 participants) were included. Adjuvants evaluated were azathioprine, mycophenolate mofetil, cyclophosphamide, cyclosporine, intravenous immunoglobulin, plasma exchange, and infliximab; not all were included in every analysis. Although adjuvants were not beneficial for achieving remission, they were found to collectively decrease the risk of relapse by 29% (relative risk 0.71, 95% confidence interval 0.53-0.95).
LIMITATIONS
Different adjuvants were pooled together.
CONCLUSION
Adjuvants have a role in pemphigus treatment, at least in reducing the risk of relapse. Further randomized controlled trials of other promising modalities are warranted.

Giornale Italiano Di Dermatologia E... Apr 2020Treatment with antihypertensive drugs may be associated with different dermatological adverse reactions.
INTRODUCTION
Treatment with antihypertensive drugs may be associated with different dermatological adverse reactions.
EVIDENCE ACQUISITION
We systematically reviewed the literature available on the MEDLINE (PubMED) databases, up to July 2018. We searched for the terms "calcium-channel blockers" or "angiotensin-converting enzyme inhibitors" or "angiotensin II receptors blockers" or "diuretics" or "beta blockers" AND "dermatological effects" or "skin disease."
EVIDENCE SYNTHESIS
The most important cutaneous events occurring during treatment with calcium-channel blockers are represented by pedal edema and photosensitivity with consequent increased risk of skin cancer. Moreover, other adverse reactions are eczematous and psoriasiform dermatitis, subacute cutaneous lupus erythematosus, and rarely toxic epidermal necrolysis. In patients taking angiotensin-converting enzyme inhibitors or angiotensin II receptors blockers, angioedema, psoriasis and pemphigus can be exacerbated. Furthermore, some authors associated the use of these medications with the onset of skin neoplasms. As for diuretics, the most relevant cutaneous reactions are represented by subacute cutaneous lupus erythematosus and leukocytoclastic vasculitis. Photosensitivity is another important event related to diuretics use. Eventually, itching is often related to the use of thiazides, particularly in elderly patients. With regards to beta blockers, we should remember a significant association with psoriasis, lichen planus, subacute cutaneous lupus erythematosus, and an increased risk of skin cancer.
CONCLUSIONS
During antihypertensive treatment, several dermatological reactions may occur. Clinicians should inform their patients of the increased risk of cutaneous lesions associated with the use of these drugs, and perform periodic examination of the skin.

Pemphigus encompasses a rare heterogeneous group of autoimmune blistering diseases characterized by cutaneous and/or mucosal blistering. Multiple factors, such as some specific types of drugs, have been found to be involved in the induction of pemphigus. Here, we have designed a systematic review by searching PubMed/Medline and Embase databases to find the drugs, involved in pemphigus induction and exacerbation (updated on 19 August 2019). From 1856 initially found articles, 134 studies (198 patients; 170 patients in the drug-induced patients and 28 in exacerbation group) have been included. Regarding drug-induced cases, the mean age was 57.19 ± 16.9-year-old (ranged 8-105), and patients had developed pemphigus within a mean of 154.27 days. Pemphigus vulgaris (38.9%), pemphigus foliaceus (33.5%), and paraneoplastic pemphigus (3.6%) were the most common subtypes. Furthermore, penicillamine (33.1%), captopril (7.7%), and bucillamine (6.5%) were the most reported drugs related to pemphigus induction; penicillamine was associated with the most persistent disease. Regardless of disease subtype, cutaneous, mucocutaneous, and mucosal involvements were reported in 68.6%, 30.1%, and 1.3% of patients, respectively. In total, the IgG deposition in the pathological studies, being positive for autoreactive antibodies in the serum against desmoglein 3 (Dsg3), and desmoglein 1 (Dsg1), were reported in 93%, 34.9%, and 72.7% of reported patients, respectively. Regarding the management of such patients, in 75% of healed cases, treatment (mainly transient systemic and topical corticosteroids and/or azathioprine) was needed besides stopping the probable pemphigus-inducing culprit drug, while drug cessation was enough to control the disease in 25%. As the outcomes, the lesions in 129 of 147 (87.8%) patients had been healed, while in 18 (12.2%), no healing was reported; fifteen out of 18 had died. In conclusion, some specific groups of treatments can induce pemphigus, including penicillamine, captopril, and bucillamine; despite the similar clinical and pathological manifestations to classical pemphigus, most of the cases are less severe and have a better prognosis.

Meta-Analysis
BACKGROUND
Pemphigus vulgaris is a life-threatening autoimmune bullous disease characterized by flaccid blister formation. As there has been no macroscopic assessment of epidemiological characteristics, its disease burden in the general population remains unknown.
OBJECTIVES
The aim of this study was to assess the global incidence rate of pemphigus vulgaris in the general population.
METHODS
The search was conducted in databases including Medline, Embase, Web of Science, and the Cochrane Library from inception to May 1, 2022. We included original studies that either reported the incidence of pemphigus vulgaris or provided raw data for calculating. Studies based on a specific population instead of the general population were excluded. Individual studies were summarized using random-effects mode. The pooled incidence rate of pemphigus vulgaris among the general population and subgroups was obtained. Heterogeneity (I2 statistic) was assessed with the χ2 test on Cochrane's Q statistic.
RESULTS
Twenty-nine studies were eligible for final analysis, and the pooled incidence rate of pemphigus vulgaris was 2.83 per million person-years (95% CI, 2.14-3.61). The incidence rate was similar between men and women and remained stable in the past half-century. Southern Asia showed the highest rate among subcontinents that had more than one study conducted as 4.94 per million person-years (95% CI, 2.55-8.10). Economic levels do not seem to have any bearing on incidence.
CONCLUSIONS
Despite the substantial heterogeneity among studies, this meta-analysis revealed the worldwide incidence rate of pemphigus vulgaris for the first time and may assist in assessing global disease burden and promoting health policy.

PROBLEM
Pemphigus vulgaris may worsen during pregnancy, leading to both maternal and fetal complications. The relationship between pemphigus vulgaris and pregnancy remains unclear, and the outcomes and treatments of pemphigus vulgaris during pregnancy have not been extensively discussed.
METHOD OF STUDY
This article systematically reviews the literature, focusing on the relationship between pemphigus vulgaris and pregnancy. We conducted comprehensive searches in PubMed, Embase, Cochrane Library, and Web of Science databases, identifying 42 studies reporting the disease course, pregnancy outcomes, and management of both pregnancy and pemphigus vulgaris.
RESULTS
A total of 57 cases were included in the analysis, categorized into three distinct forms: pemphigus vulgaris onset before pregnancy (n = 33), onset during pregnancy (n = 20), and onset during the postpartum period (n = 4). Fifty four cases reported treatment strategies, among them, 44 cases (81.5%) initially received systemic corticosteroid therapy during pregnancy. Out of these cases, 7 (15.9%) did not achieve successful remission and required alternative treatment approaches. In terms of pregnancy outcomes, 23 out of 62 neonates (37.1%) exhibited skin lesions or tested positive for anti-dsg IgG in their serum, while 16 neonates (25.8%) experienced other complications.
CONCLUSIONS
These findings highlight the importance of effectively managing pemphigus vulgaris during pregnancy to ensure optimal outcomes.

Review
The aim of this study was to critically evaluate the diagnostic yields of direct immunofluorescence (DIF) analysis on perilesional and normal-appearing mucosa biopsy samples, to determine the optimal biopsy site for patients presenting with oral pemphigus vulgaris (PV) or mucous membrane pemphigoid (MMP). Electronic databases and article bibliographies were searched in December 2022. The primary outcome was the rate of DIF positivity. Of 374 records identified after the elimination of duplicates, 21 studies with 1027 samples were ultimately included. Meta-analysis revealed a pooled DIF positivity rate of 99.6% (95% confidence interval (CI) 97.4-100.0%, I = 0%) for PV and 92.6% (95% CI 87.9-96.5%, I = 44%) for MMP for biopsies from perilesional sites, and of 95.4% (95% CI 88.6-99.5%, I = 0%) for PV and 94.1% (95% CI 86.5-99.2%, I = 42%) for MMP for biopsies from normal-appearing sites. For MMP, there was no significant difference in the rate of DIF positivity between the two biopsy sites (odds ratio 1.91, 95% CI 0.91-4.01, I = 0%). The results suggest that the perilesional mucosa remains the optimal biopsy site for DIF diagnosis of oral PV, while the normal-appearing mucosa biopsy is optimal for oral MMP.

Review
UNLABELLED
What is known and objective: Pemphigus is a severe, potentially life-threatening autoimmune blistering disease. The use of corticosteroids has dramatically improved the prognosis and changed its course. However, current morbidity of pemphigus is largely iatrogenic, caused by side effects of the long-term, high-dose corticosteroid therapy that is necessary to sustain disease control. In order to minimize side effects, a range of corticosteroid-sparing immunosuppressive agents have been introduced, including mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS). A systematic review was performed to evaluate the effectiveness of MMF and EC-MPS in the treatment of pemphigus vulgaris and pemphigus foliaceus.
METHODS
A retrospective literature search was conducted through multiple electronic databases (PubMed, Medline, The Cochrane database of systematic reviews) for reports on the use of mycophenolic acid (MPA) in the treatment of pemphigus vulgaris and pemphigus foliaceus.
RESULTS
Sixteen studies with a total of 239 patients have evaluated the treatment of pemphigus vulgaris and pemphigus foliac;eus with MPA. The majority of patients had refractory disease treated with corticosteroids as monotherapy or associated to adjuvant agents.
DISCUSSION
The results of this review suggest that MPA, as MMF or EC-MPS, may be a promising adjuvant or alternative therapy for the treatment of pemphigus vulgaris and pemphigus foliaceus. It appears safe, at least in the medium term and its adverse events seem to be dose dependent.
WHAT IS NEW AND CONCLUSION
The use of mycophenolate is first-line adjuvant therapy in the treatment of pemphigus vulgaris and pemphigus foliaceus.
