Gingival Manifestations in Oral Chronic Autoimmune Bullous Diseases: A Retrospective Study

Background and Objectives: Desquamative gingivitis (DG) is a clinical term indicating "peeling gums" and is associated with different oral manifestations. In this study, we aimed to assess the association between DG and autoimmune blistering mucocutaneous diseases (ABMD) with oral manifestations. Materials and Methods: A retrospective study including 88 patients diagnosed between 1998 and 2019 with ABMD (intraepithelial and subepithelial autoimmune blistering diseases) was performed at the Oral Medicine Department, Faculty of Dentistry, "Carol Davila" University of Medicine and Pharmacy in Bucharest. For each patient, the sociodemographic and anamnestic data, as well as clinical features of oral lesions (location), histological evaluation, and direct immunofluorescence data were collected. Results: Most of the patients involved in the study were female (78.4%). In total, 34 patients (38.63%) were diagnosed with subepithelial autoimmune diseases (SAD) and 54 (61.36%) had intraepithelial autoimmune diseases (IAD). Differences in the anatomic distribution of oral involvement were found between SAD and IAD. The presence of DG was significantly more common in patients with SAD compared to those with a diagnosis of IAD. Conclusions: Specific anatomical locations of the oral lesions are significantly associated with different subtypes of ABMD, with gingiva and hard palate mucosa being more involved in SAD and the soft palate and buccal mucosa in IAD. Desquamative gingivitis is a clinical sign that raises diagnostic challenges for several conditions in oral medicine.

Management of auto-immune blistering disease in an older patient with severe intellectual disability

Management of chronic oral mucosal diseases might be challenging in older individuals with intellectual disability because of associated comorbidities, variable clinical presentations, and various barriers imposed by the intellectual disability. This report describes the presentation and management of pemphigus vulgaris in an older female with severe intellectual disability.

Diagnostic delay in autoimmune oral diseases

Autoimmune diseases (ADs) affect about 5% of the general population, causing various systemic and/or topical clinical manifestations. The oral mucosa is often affected, sometimes as the only involved site. The misdiagnosis of oral ADs is an underreported issue. This narrative review focuses on diagnostic delay (DD) in oral ADs (oral lichen planus [OLP], oral Pemphigus Vulgaris, mucous membrane pemphigoid, oral lupus erythematosus, orofacial granulomatosis, oral erythema multiforme [EM], and Sjogren syndrome). Extensive literature research was conducted via MEDLINE, Embase and Google Scholar databases for articles reporting the time spent to achieve the correct diagnosis of oral ADs. Only 16 studies reported DD in oral ADs. Oral autoimmune vesiculobullous diseases are usually diagnosed after 8 months from the initial signs/symptoms, the Sjogren Syndrome diagnosis usually requires about 73 months. No data exist about the DD in OLP, oral lupus erythematosus, orofacial granulomatosis, and oral EM. The diagnosis of oral ADs can be difficult due to the non-specificity of their manifestations and the unawareness of dentists, physicians, and dental and medical specialists about these diseases. This can lead to a professional DD and a consequential treatment delay. The delay can be attributed to the physicians or/and the healthcare system (Professional Delay) or the patient (Patient's Delay).

Burden of pemphigus vulgaris with a particular focus on women: A review

Pemphigus vulgaris is a chronic autoimmune mucocutaneous blistering disorder. Apart from the disease itself, other aspects of patients' life, including psychological, social, and financial, can be affected. Women are particularly more disposed to the impact of the disease due to their physiological characteristics, the specific periods of pregnancy and lactation as well as their social and familial role. In this review, we summarized the burden of pemphigus vulgaris on various aspects of women's lives. It is essential to understand these problems and provide appropriate support for patients with such a burdensome disease.

Retrospective study of gingival involvement in pemphigus: a difficult to treat phenomenon

BACKGROUND

Pemphigus is a group of autoimmune diseases characterized by flaccid lesions on the skin and mucous membranes. In pemphigus vulgaris, the most common subtype of pemphigus, lesions might be appeared anywhere on the oral mucosa, mostly in the buccal mucosa. However, the gingiva is a less frequently affected site.

METHODS

Here, we performed a retrospective study at Tehran University of Medical Sciences, covering a two-year period to identify pemphigus patients with active lesions confined to the gingiva.

RESULTS

Considering 1787 initially evaluated pemphigus cases, 512 (28.6%) were found to have a history of gingival involvement. Among them, 31 patients had only gingival involvement during their last visit, including 29 (93.5%) women and only two (6.5%) men. The mean of disease duration in this group was 5.29±3.46 years, and they had gingival involvement for a mean of 23.9±19.3 months. Of 28 patients, nine were negative for anti-Dsg3 and 24 were negative for anti-Dsg1. In 24 patients, who received rituximab, the mean PDAI specifically for gingiva was 4.76±0.74 at baseline, which had changed to 4.13±0.75 and 3.26±0.63 three and six months after rituximab administration, respectively. After three months, gingival lesions were either entirely resolved (n=3), partially resolved (n=11), remained unchanged (n=2), or progressed (n=7).

CONCLUSIONS

Gingiva-confined presentation of lesions in pemphigus could be non-anti-Dsg1/3 dependent in some patients. Such patients do not respond well to conventional treatments and rituximab therapy. More studies on the pathogenesis of gingiva-confined presentation of pemphigus are required. This article is protected by copyright. All rights reserved.

Knowledge about oral manifestations of systemic diseases among medical and dental students from Jordan: An interdisciplinary educational gap

OBJECTIVE

To assess the ability of medical students to recognize oral manifestation of selected systemic diseases and compare their performance with dental students.

MATERIALS AND METHODS

A total of 400 senior medical and dental students were approached to participate. The study protocol involved two parts; a self-administered survey and a direct interview involving clinical photographs for oral signs of systemic diseases.

RESULTS

A total of 283 (70.8%) agreed to participate and completed the two- part study. The study population was made of 110 (38.9%) [82 females and 28 males] dental students, and 173(61.1%) [98 females and 75 males] medical students. The knowledge score regarding questions about the normal mouth and oral structures was 15.7 ± 6 out of 22. Dental students had a significantly higher knowledge score about normal mouth and oral structures (20.9 ± 4; range from 17 to 22) compared to medical students (10.6 ± 7; range from 4 to 21) (p = .029). The knowledge score regarding questions about oral manifestations of systemic diseases was 26.8 ± 6 out of 40. Dental students had a significantly higher knowledge score about oral manifestations of systemic diseases (30.8 ± 7; range from 15 to 37) compared to medical students (22.9 ± 4; range from 10 to 36) (p = .031). Only 24.3% (n = 42) medical students reported having adequate training to be able to distinguish between normal mouth and diseases. Nearly all medical students (91.3%; n = 158) felt that it is important to have more formal training in oral examination and disease diagnosis.

CONCLUSION

Medical students lack adequate knowledge, diagnostic ability, and confidence with regard to diagnosis of oral signs of systemic diseases. To ensure that medical students have necessary skills in assessing oral diseases, curricula revisions and modifications are required, and specific oral health-related learning outcomes should be introduced and reinforced through clinical training.

Diagnostic Concordance between Optical Coherence Tomography and Histological Investigations for Immune-Mediated Desquamative Gingivitis: Observational Study

Desquamative gingivitis (DG) denotes a heterogeneous immune-mediated disease for which early diagnosis represents a great challenge. The main aim of this study is to validate diagnostic concordance between specific Optical Coherence Tomography (OTC) patterns for DG related to oral Lichen Planus (OLP), Pemphigus Vulgaris (PV), and Mucous Membrane Pemphigoid (MMP) and definitive histological diagnosis. Forty-three patients with suspected immune-mediated DGs, were progressively recruited. Before biopsy, an OCT preliminary evaluation was performed using specific pre-determined OCT diagnostic patterns (i.e., morphology and localization of blisters, status of the basal membrane, epithelial thickness, presence/absence of acantholytic cells into blister and/or inflammatory infiltrate) related to OLP, PV and MMP. After histological confirmation, OCT and histological diagnoses were compared. Using pre-determined patterns, OCT diagnoses of DGs were: 22 (51%) OLP, of which 11 (26%) were with the bullous variant, 4 (9%) PV and 6 (14%) MMP. The same diagnoses were found by histological investigations (with the main OCT discriminatory potential for the bullous variant of OLP). The concordance between the two diagnostic methods was confirmed by the Fisher exact test (p-value < 0.01). These specific OCT patterns show a diagnostic reliability in 100% of the cases investigated, suggesting their accuracy to support the complex diagnosis and management of immune-mediated DGs.

Immune-Mediated Desquamative Gingivitis and Optical Coherence Tomography Diagnostic Patterns: Clinical Implication from a Systematic Review

Desquamative Gingivitis (DG) comprises heterogeneous clinical manifestations of numerous immune-mediated muco-cutaneous diseases. Optical Coherence Tomography (OCT) has been proposed as a valuable diagnostic support even if, to date, there are no standardized OCT-diagnostic patterns applicable to DGs. A systematic review was performed to detect existing data on in vivo OCT diagnostic patterns of the most common immune-mediated DGs (i.e., pemphigus vulgaris, mucous membrane pemphigoid and oral lichen planus). It has been found that OCT exhibits specific patterns that address the diagnosis of DG by pemphigus vulgaris (i.e., intraepithelial unilocular blister, reduced epithelial thickness, presence of acantholytic cells in the blister) and by mucous membrane pemphigoid (i.e., subepithelial multilocular blister, presence of inflammatory infiltrate), but not by oral lichen planus. These patterns could offer an attractive diagnostic OCT framework to support the clinical preliminary assessment and monitoring of these complex pathological conditions.

Desquamative gingivitis: a challenging diagnosis for clinicians

Introduction Diagnosis of underlying causes for desquamative gingivitis (DG) is often delayed in clinical settings, but little is known about factors influencing its delayed diagnosis. We investigated the diagnostic patterns and associated factors in a cohort of patients presenting primarily with DG.Materials and methods A total of 41 patients presenting primarily with DG were interviewed to evaluate professional and patient diagnostic delays. Severity of DG was evaluated using the desquamative gingivitis clinical score (DGCS) proposed by Arduino <i>et al.</i> (2017).Results The study sample was composed of 29 females and 12 males. On average, patients waited 10.8 ± 10 months (range 4-20 months) before seeking their first professional consultation (that is, patient delay). Less severe disease and female gender were significantly associated with longer patient delay. Patients consulted an average of 4.1 ± 2 healthcare professionals (range two to six) before a definitive diagnosis was reached, with an average professional delay of 7.3 ± 5 months (range 2-11 months). Professional delay was positively correlated with the number of professional consultations (r = 0.69) and absence of other oral mucosal lesions or extraoral involvement.Conclusions Considerable diagnostic delay is a feature of the natural history of DG. Increased patient knowledge and professional awareness regarding DG symptoms and diagnostic measures is needed to reduce diagnostic delay and improve patients' experience with this disease.

Clinical presentation and diagnostic delay in pemphigus vulgaris: A prospective study from Turkey

BACKGROUND

To evaluate the diagnostic patterns and factors that may influence delays in the diagnosis of pemphigus vulgaris (PV) with oral involvement.

MATERIALS AND METHODS

In this prospective cohort study, 36 newly diagnosed PV patients with oral involvement were clinically examined and interviewed about the natural history of the oral lesions, number of medical consultations (Med consultation), medical treatment history, and diagnostic delay time (DD time).

RESULTS

Thirty (83%) PV patients presented initially with oral mucosal involvement (OMI) and 6 (17%) presented initially with skin involvement (SI). The mean DD time was 6.19 ± 3.82 months, and the mean number of Med consultation was 5.8 (n = 36). The means of all the parameters were significantly higher for the OMI patients than for the SI patients (P < .05). All of the patients with OMI had been misdiagnosed. The DD time was significantly longer in patients who presented initially with desquamative gingivitis (8.25 ± 3.81) than patients who presented with ulcers and erosions (4.78 ± 1.11) (P < .05). There was a statistically significant positive correlation between DD time and Med consultation (r = 0.91).

CONCLUSION

Even with the high frequency of oral involvement and easy access to the oral cavity, diagnostic delays are still common for patients with oral PV. This underlines the need for education to improve healthcare providers' awareness and knowledge of the clinical oral presentation of PV.

Oral management of pemphigus vulgaris in the intensive care unit

Pemphigus vulgaris (PV) is a rare and potentially lethal autoimmune disease that affects the skin and mucous membranes. Injuries caused by the disease cause pain, risk of infection, and other complications that result in a high mortality rate. Frequently, management of the PV requires intensive care and a multidisciplinary approach. Oral lesions of PV are usually the first clinical signs of the disease and the last lesions to heal, requiring treatment by a specialized dental team. The aim of this study was to report two clinical cases of PV with involvement of the oral mucosa. The patients were admitted to an intensive care unit, and underwent multidisciplinary management of their condition along with low-level laser therapy. Both cases demonstrated the importance of specialized dental care in improving the quality of life of patients with PV.

Diagnostic delay and suboptimal management in persistent idiopathic facial pain and persistent dentoalveolar pain; a cross-sectional study

OBJECTIVES

The aim of this study was to explore the diagnostic and therapeutic challenges encountered by patients with persistent idiopathic facial pain (PIFP) and to investigate factors influencing its delayed diagnosis.

STUDY DESIGN

In this cross-sectional study, 34 patients with newly diagnosed PIFP were interviewed. Data about diagnostic delay, number and nature of previous consultations, and previous medical and surgical interventions were recorded. Pearson's correlation and Student t test were used to examine the differences among the variables in relation to diagnostic delay.

RESULTS

The average time between the onset of symptoms to correct diagnosis was 19.3 ± 11.1 months. Diagnostic delay was significantly longer in patient with pain localized to intraoral sites (22.6 ± 7.4) compared with patients with extraoral pain (16.1 ± 9.3). The average number of health care professionals consulted before correct diagnosis was 3.7 ± 2.3. General dental practitioners were the most commonly consulted health care professionals (n = 27; 79.4%). On average, patients were given 2.3 ± 0.24 misdiagnoses before the correct diagnosis was determined and were prescribed 3.5 ± 2.4 classes of drugs. Twenty-five patients (73.5%) underwent unnecessary surgical/dental interventions.

CONCLUSIONS

Patients with PIFP are frequently misdiagnosed, leading to prescription of ineffective medications and unnecessary investigations and surgical interventions. Educational efforts should emphasize on improving knowledge and awareness of this condition.

Oral hygiene instructions and professional control as part of the treatment of desquamative gingivitis. Systematic review

Background

The aim of this present article was to evaluate the scientific evidence on the efficacy of daily hygiene and professional prophylaxis for treatment of desquamative gingivitis.

Material and Methods

The present systematic review was conducted following the PRISMA protocol. Searches were carried out in Pubmed, Embase, Web of Science and Cochrane Library up to July 2018, randomized clinical trials and cohort studies on desquamative gingivitis (DG), and oral diseases joined to DG.

Results

After screening, we found that nine publications met the eligibility criteria eight cohort studies and one randomized control trial. The diagnosis of the diseases corresponded to oral lichen planus (n=185), mucous membrane pemphigoid (n=13); plasma cell gingivitits (n=15) and pemphigus vulgar (n=11). The follow-up was between a week and a year after instructing patients. Dental daily hygiene and professional prophylaxis, at least with supragingival scaling and polishing have significantly improved the extension of the lesion and reduced the activity of DG, and gingival bleeding in all patients. Furthermore, these techniques have also reduced pain and gingival plaque.

Conclusions

In conclusion the studies presented support the efficacy of maintaining personal and professional oral hygiene in patients with GD, reducing the clinical signs of the disease, regardless of its pathogenesis.
