To evaluate the long-term clinical efficacy of apremilast in Behçet's disease (BD) and its effect on serum cytokine levels. This study included 15 BD patients who were treated with apremilast. The rates of change in oral and genital ulcers, skin lesions, arthritis, and arthralgia were evaluated every 3 months for 12 months. The efficacy of apremilast was compared between patients with and without oral ulcer remission. Changes in the serum levels of interferon-gamma (IFN-γ), tumor necrosis factor alpha (TNF-α), interleukin (IL)-10, IL-17A, IL-6, IL-8, and IL-23 between baseline and 3 months after apremilast initiation were compared. After 3 months, oral and genital ulcers disappeared in most cases. The skin and joint lesions tended to improve for up to 6 months; however, recurrence was observed after 9 months. The improvement of genital ulcers was earlier in the oral ulcer remission group than the oral ulcer non-remission group, with the genital ulcers disappearing within the first 3 months. The baseline levels of serum cytokines, analyzed in seven patients, did not exhibit significant associations with specific organ lesions. After administration of apremilast, the TNF-α and IL-23 levels significantly decreased; however, the IFN-γ, IL-6, IL-8, and IL-10 levels did not show significant changes. The rates of decrease in the serum IL-6, IFN-γ, and IL-10 levels were greater in patients with improved oral ulcers. Modulation of serum cytokine levels with apremilast might underlie the efficacy of apremilast in oral ulcers in BD patients., (© 2022 Wiley Periodicals LLC.)

Objective: To review common presentation of oral ulcers in children and discuss management of symptoms and subsequent investigation., Conclusion: Although a common presentation in children, diagnosis can be challenging. Thorough history taking is critical towards diagnosis and supports signposting to relevant specialities. Clinicians should be able to support first-line symptomatic management of oral ulceration., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Pemphigus vulgaris is a rare autoimmune mucocutaneous blistering disease clinically presenting as vesicles, bullae, and erosion and histologically characterized by suprabasal split and acantholysis. It usually affects mucous membranes and skin. Recurrent oral ulcers can only be the clinical manifestation before progressing into skin lesions. This can lead to the delayed diagnosis of this disease. Here we report a case of pemphigus vulgaris which was diagnosed after years of suffering from an oral ulcer that eventually progressed to widespread skin blistering and ulceration. The patient was treated with oral prednisolone which showed improvement within a week. Physicians should consider the differential diagnosis of pemphigus vulgaris in patients presenting with a recurrent oral ulcer., Keywords: delayed diagnosis; oral ulcer; pemphigus vulgaris.

A 5-year-old girl, the first-born child from a nonconsanguineous marriage, presented with multiple clear fluid-filled lesions present for 2 years, covering the body and when ruptured healed spontaneously with scarring. Sunlight aggravated the lesions. The child had had a hoarse voice since she was 1 year old. She also had developed multiple painful, nonhealing ulcers in mouth for 1 month duration she was 1 month old. There was no history of discoloration of urine or staining of undergarments, recurrent episodes of abdominal pain, headache, memory loss, or seizures. ( SKINmed . 2022;20:224-227).

The complexity of oral ulcerations poses considerable diagnostic and therapeutic challenges to oral specialists. The expert consensus was conducted to summarize the diagnostic work-up for difficult and complicated oral ulcers, based on factors such as detailed clinical medical history inquiry, histopathological examination, and ulceration-related systemic diseases screening. Not only it can provide a standardized procedure of oral ulceration, but also it can improve the diagnostic efficiency, in order to avoid misdiagnosis and missed diagnosis., (© 2022. The Author(s).)

Familiarity with common oral conditions allows clinicians to observe and treat patients in the primary care setting or refer to a dentist, oral surgeon, otolaryngologist, or other specialist. Recurrent aphthous stomatitis (canker sores) is the most common ulcerative condition of the oral cavity. Recurrent herpes simplex labialis and stomatitis also commonly cause oral ulcers. Corticosteroids, immunocompromise, antibiotics, and dentures can predispose patients to oral candidiasis. Benign migratory glossitis (geographic tongue) occurs in up to 3% of the population but generally lacks symptoms, although some people experience food sensitivity or a burning sensation. Hairy tongue is associated with a low fiber diet, tobacco and alcohol use, and poor oral hygiene in older male patients. Generally, hairy tongue is asymptomatic except for an unattractive appearance or halitosis. Tobacco and alcohol use can cause mucosal changes resulting in leukoplakia and erythroplakia. These can represent precancerous changes and increase the risk of squamous cell carcinoma. Mandibular and maxillary tori are common bony cortical outgrowths that require no treatment in the absence of repeat trauma from chewing or interference with dentures. Oral lichen planus occurs in up to 2% of individuals and can present as lacy reticulations or oral erosions and ulcerations. Traumatic buccal mucosal fibromas and labial mucoceles from biting can be excised.

We conducted an integrative review on oral manifestations in patients with COVID-19 based on the current available literature evidence. A bibliographic search was carried out on March 11, 2021, among published studies in the years 2019-2021 in the PubMed database and based on the search strategy ("COVID-19" AND "oral lesions" OR "oral mucositis" OR "oral manifestation"). After applying the inclusion and exclusion criteria, 29 articles were considered suitable for this review. A total of 110 cases of patients with COVID-19 who had oral manifestations were reported. The presence of ulcerated lesions was the most common finding, having a herpetiform and aphthous clinical pattern observed in most cases. Macules, petechiae, hemorrhagic blisters, pustular enanthem, mucositis, and halitosis were also among the most frequently described oral manifestations. The tongue was the most commonly affected site, followed by the palate and lip. Most of the reported cases were diagnosed only by the clinical aspect of the lesion associated with a positive SARS-CoV-2 test or the presence of other COVID-19 symptoms. Current scientific evidence still could not affirm that most of the oral lesions observed in patients with COVID-19 are related to the virus's direct or indirect action on the oral mucosa. To confirm this association, prospective and longitudinal studies are further needed, together with a larger number of patients, complemented by histopathological examination of these lesions. Additionally, molecular techniques, such as immunohistochemistry and in situ hybridization, may be necessary to perform the differential diagnosis with other oral lesions., (© 2021 the International Society of Dermatology.)

Oral mucositis (OM) is a common, highly symptomatic complication of cancer therapy that affects patients' function, quality of life, and ability to tolerate treatment. In certain patients with cancer, OM is associated with increased mortality. Research on the management of OM is ongoing. Oral mucosal toxicities are also reported in targeted and immune checkpoint inhibitor therapies. The objective of this article is to present current knowledge about the epidemiology, pathogenesis, assessment, risk prediction, and current and developing intervention strategies for OM and other ulcerative mucosal toxicities caused by both conventional and evolving forms of cancer therapy., (© 2021 The Authors.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus responsible for coronavirus disease 2019 (COVID-19), which manifests as a flu-like respiratory infection affecting multiple organ systems, including the gastrointestinal system, central nervous system, cardiovascular system, skin, and mucosa. In this review, we investigated the literature on specific manifestations of COVID-19 in the oral mucosa. An online literature search in PubMed, Scopus, Google Scholar, and Medline was conducted to retrieve relevant studies on confirmed COVID-19 patients with oral mucosa findings published between December 31, 2019, and April 07, 2021. After an independent review by two authors, 39 articles considering 59 laboratory-confirmed cases of SARS-CoV-2 infection were included in the final analysis. The most common finding, reported in 29 patients (43.9%), was Kawasaki-like syndrome. In addition, oral ulcers including aphthous, hemorrhagic, and necrotic ulcers were reported in 24 patients (36.3%). Other lesions reported included pustules, macules, bullae, maculopapular enanthema, and erythema multiforme-like lesions. Concomitant skin lesions were present in 60.6% of patients. Fever was reported in 86.2% of patients. Forty-eight patients (76.1%) were hospitalized. Loss of taste and smell was present in 30.8% of the patients. A comprehensive understanding of the dermatologic manifestations of COVID-19 can improve and facilitate patient management and referrals., (© 2021 the International Society of Dermatology.)

Objectives: The current trial was conducted to assess the effect of diode laser therapy compared to topical corticosteroid in management of oral ulcers of BD., Materials and Methods: Fifty patients were divided randomly into two parallel groups. The first group received 980 nm diode laser; the second group received topical corticosteroid (0.1% triamcinolone acetonide). The outcome measures included oral ulcer activity index (composite index), pain (VAS), number of oral ulcers, healing time, and oral health-related quality of life (OHIP-14). The collected data were analyzed for any statistical significance., Results: A statistically significant difference was detected between laser and corticosteroid groups favoring laser on comparing composite index and VAS scores on the first and third days and on comparing number of ulcers on the third and fifth days. A statistically significant difference was detected between laser and corticosteroid groups on comparing scores of the questions assessing discomfort with eating food, irritability with other people, taste worsening, unsatisfactory diet, and painful aching on the first and/or third days. No adverse effects were reported by participants of both groups., Conclusions: Diode laser is efficient safe treatment modality for management of BD-associated oral ulcers. Diode laser was more efficient than triamcinolone acetonide in controlling pain and reducing oral ulcer activity., Clinical Relevance: Laser therapy is efficient safe modality that could spare BD patient from adding a new medication to their long list, being just one visit compared to other regular daily regimen medications., Trial Registration: ClinicalTrials.gov registration number: NCT03771768., (© 2021.

Background: Little is known about the real-time cause-effect relations between IL-6 concentrations and SLE symptoms., Methods: A 52-year-old woman with mild SLE activity collected her entire urine for the determination of IL-6/creatinine and protein/creatinine levels (ELISA, HPLC) for a period of 56 days in 12 h intervals (total: 112 measurements). Additionally, she answered questionnaires (VAS) on oral ulceration, facial rash, joint pain, fatigue and tiredness and measured her temperature orally twice a day. Time-series analyses consisted of ARIMA modeling and cross-correlational analyses (one lag = 12 h, significance level = p < 0.05)., Results: Statistical analyses showed that increased urinary IL-6 concentrations preceded increased urinary protein levels by 36-48 h (lag3: r=+.225; p =.017) and that, in the opposite direction of effect, increased urinary protein preceded urinary IL-6 decreases by 12-24 h (lag1: r=-.322; p <.001). Moreover, urinary IL-6 increases co-occurred with increased oral ulceration (lag0: r=+.186; p =.049); after 48-60 h, however, IL-6 increases showed a strong tendency to precede oral ulceration decreases (lag4: r=-.170; p =.072). Increases in facial rash preceded decreases in urinary IL-6 after 84-96 h (lag7: r=-.215; p =.023). As to fatigue, increases in urinary IL-6 co-occurred with decreased fatigue (lag0: r=-.193; p =.042); after 84-96 h, however, IL-6 increases preceded fatigue increases (+lag7: r =+.189; p =.046). Finally, joint pain, tiredness and body temperature did not significantly correlate with urinary IL-6 concentrations in either direction of effect., Conclusions: The results of this evaluation point to real-life feedback mechanisms between immune activity and SLE symptoms. Comparison with a previous evaluation of this patient suggests a counterregulatory mechanism between Th1 activity and IL-6. These findings are preliminary and require replication to draw firm conclusions about the real-time relation between IL-6 and SLE disease activity., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Schubert, Seizer, Chamson, König, Sepp, Ocaña-Peinado, Schnapka-Köpf and Fuchs.)

Objectives: The following case presents a pediatric patient with Riga-Fede disease (RFD), a rare disorder in children under 2 years of age characterized by sublingual ulceration of the tongue due to trauma from repeated rubbing against the primary teeth. Riga-Fede disease is well reported in dental literature but is relatively unknown to the general pediatric community. It can be confused with nonaccidental trauma (NAT) from forced feeding or other abusive trauma because it presents with injury of oral structures including the sublingual frenulum and often results in problems with growth. This case highlights the importance for physicians to recognize RFD as a source of isolated oral injury that is distinct from NAT. Although approximately 35 cases of RFD have been reported in the literature, this is the first case to describe the process of distinguishing this disease from child abuse., Methods: We present a case of an 8-month-old female infant who presented with extensive injury of her ventral tongue from RFD who underwent a full workup for NAT. We review the literature for guidance on diagnosing RFD and discuss how to distinguish it from abuse., Results: Infants with characteristic ulceration of the ventral tongue opposing new teeth and with no other medical, social, or developmental concerns do not need to undergo further workup. Clinical examination and thorough history are sufficient to make the diagnosis., Conclusions: Traumatic intraoral injury in nonmobile children is highly concerning for child abuse. However, RFD is a well described cause of sublingual ulceration in infants that is not associated with abuse., Competing Interests: Disclosure: K.W.F. provides legal consultation in child abuse cases. The authors declare no conflict of interest., (Copyright © 2019 Wolters Kluwer Health, Inc. All rights reserved.)

Ulceration of the oral cavity is common and a frequent reason for referral to secondary and tertiary centres. Epstein-Barr virus (EBV)-related mucocutaneous ulceration, however, is a rare cause of oral ulceration that has been described only recently. Histologically these lesions resemble lymphomas; however, their management and prognosis differ significantly. We present a case of EBV-induced oral ulceration and discuss the diagnosis and management of and available literature for the condition, which was treated successfully through conservative measures alone.

Background: Nutritional deficiencies are common worldwide and is most notable in low and middle income countries. In the early weeks of September 2018, oral sores mostly affecting the tongue were reported in three central schools under Tsirang district, Bhutan. A total of 204 students were affected in the three central schools. All the affected students have been assessed on the outbreak and nutritional survey was conducted in the three schools., Methods: A total of 204 students who complained of different oral lesions in the affected three schools were screened by the dental surgeon for clinical assessment and administered questionnaire for nutritional assessment by the nutritionist. Twenty-one students randomly selected were sent for blood tests for micronutrient assays and complete blood count. 41 students were tested for Exfoliative cell cytology to test for fungal elements. The collected data was double entered and validated using Epi-Data version 3.1 and analysed using Stata 15 IC. The characteristics of the participants are presented as frequencies, percentages, mean and standard deviation (SD)., Results: Almost all the affected students in all the three schools had complaints of Burning Sensation (n = 158) followed by Pain (n = 153), Impaired Taste Sensation (n = 100) and Intolerance to Spicy Food (n = 95). Nutritional assessment analysis suggested schools not meeting the Recommended Dietary Allowance (RDA) for all components of Vitamin B complexes and Iron., Conclusion: Clinical assessments and nutritional survey analysis found inadequate vitamin rich dietary intakes among all the three schools. Implementation of a strict school feeding program with a balanced diet has been suggested accordingly., (© 2021. The Author(s).)

Objectives: This study assessed the efficacy and safety of apremilast for the oral ulcers associated with Behçet's syndrome (BS) up to 64 weeks., Methods: The phase 3, double-blind, placebo-controlled RELIEF study randomised adult patients with active BS to placebo or apremilast 30 mg twice daily for 12 weeks, followed by an extension phase with all patients receiving apremilast through Week 64 and 4-week post-treatment follow-up (upon treatment discontinuation). The primary endpoint was area under the curve for the number of oral ulcers over 12 weeks (AUCWk0-12), reflecting the number of oral ulcers over time and accounting for their recurring-remitting course. Oral ulcer number, complete and partial responses, pain and disease activity and quality of life (QoL) were also assessed throughout the study., Results: A total of 207 participants were randomised and received at least one dose of study medication; 178 entered the extension phase and 143 completed Week 64. AUCWk0-12 was significantly lower with apremilast versus placebo (p<0.0001), and oral ulcers number, pain, complete/partial responses, disease activity and QoL with apremilast versus placebo showed improvements at Week 12, which were maintained through Week 64. The most common adverse events were diarrhoea, nausea, headache and upper respiratory tract infection; no new safety concerns were observed with longer-term apremilast exposure., Conclusions: In patients with oral ulcers associated with BS, apremilast was efficacious and benefits were sustained up to 64 weeks with continued treatment. Apremilast was well tolerated, and safety was consistent with its known safety profile.

Stüve-Wiedemann syndrome (SWS) is a rare, autosomal recessive disorder, causing dysautonomia and multisystem failure. Symptoms include skeletal malformations, restricted joint mobility and desensitisation to pain. Patients with SWS presenting with intraoral lesions are extremely rare and this is probably due to their shortened lifespan. We present a case of a 9-month-old patient who presented to our Oral and Maxillofacial Surgery (OMFS)Unit with a chronic inflamed ulcer affecting the tongue, secondary to trauma from erupting central incisors. We believe that depapillation in conjunction with an increased pain threshold contributed to its development. The patient was successfully treated by extraction of the lower central incisors and intralesional steroid injections under general anaesthetic. This case highlights that patients with SWS can present to the OMFS clinician with oral lesions and that they can be safely managed under general anaesthesia., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Background: Oral and oropharyngeal cancer are significant health problems. They are both life-threatening conditions usually diagnosed at an advanced stage causing survival rates to decline., Aim: To assess and compare practices, knowledge and attitude regarding oral and oropharyngeal cancer between dental and medical practitioners., Methods: A cross-sectional study was conducted to assess knowledge, attitude and practices of oral and oropharyngeal cancer among dental and medical practitioners at King Abdulaziz Medical City, Riyadh, Saudi Arabia. 360 participants were included in the study using a convenient sampling technique. Participants were approached in their clinics and printed self-administered questionnaire were handed over to them after signing a written consent form. Frequency distribution and Chi-Square test were used for the statistical analysis and the level of significance was set at P value of .05 or less., Results: A total of 174 participants responded. Assessment of oral and oropharyngeal cancer knowledge between dental practitioners and medical practitioners showed comparable results. Regarding practices, a significant difference was seen between medical practitioners and dental practitioners in determining the duration of intra-oral ulcer to consider urgent referral (P = .006) and in number of referrals made in relation to suspicious oral lesions (P = .002). Moreover, a significant difference (P = .006) was seen between medical practitioners and dental practitioners in determining the duration of intra-oral ulcer to consider urgent referral., Conclusion: Medical and dental practitioners showed areas of differences in practice, attitude and knowledge of oral and oropharyngeal cancer that when addressed would lead to improved survival rates., (© 2021 The Authors.

Introduction: Behçet's syndrome is a chronic, multi-system, variable vasculitis of unknown etiology that can result in significant morbidity and mortality. Mucocutaneous lesions such as oral ulcers and genital ulcers are common manifestations that can affect the quality of life of patients significantly. Treatment for mucocutaneous lesions in Behçet's syndrome continues to be critical, and an unmet need remains a significant issue., Areas Covered: This review evaluates the mechanism of action of apremilast, its effect on the number and pain of oral ulcers, other manifestations, such as genital ulcers, disease activity, quality of life and safety profile in Behçet's syndrome patients. Data from clinical trials as well as observational studies were included., Expert Opinion: Two randomized placebo-controlled trials and real-world observational data suggest that apremilast is an effective and well-tolerated treatment modality for oral and genital ulcers in Behçet's syndrome. Observational studies additionally showed beneficial results for skin lesions, arthritis, and intestinal involvement.

The prevalence of oral ulcers in children is reported to be 9%, however diagnosis of oral lesions can be challenging, being an unspecific symptom of several diseases. Differential diagnosis can range from classic infectious disease of childhood (e.g. herpangina, hand-foot-and-mouth-disease) over nutritional deficiencies, gastrointestinal disorders, inflammations (e.g. pemphigus vulgaris, lichen planus, mucous membrane pemphigoid) to side effects of medications (Stevens-Johnson Syndrome) or chronic dieseases (e.g. sarcoidosis, systemic Lupus erythematodes, familial Mediterrenean fever). Therefore, children with oral ulcers are treated by many different specialists such as dentists, family doctors, paediatricians, rheumatologists, haematologists, gastroenterologists and otorhinolaryngologists.A systematic literature search and a narrative literature review about the potential 48 diseases connected to oral ulcers were performed. According to the duration of symptoms and size of the lesions, a tabular overview was created to support the clinician in making a correct diagnosis, additionally different treatment options are presented.

Background: Chikungunya fever is considered an abrupt onset arbovirus transmitted by mosquitoes, mainly Aedes aegypti and Aedes albopictus. The disease has a significant impact on the quality of life of affected persons, and many of its numerous symptoms have not yet been properly clarified, such as the manifestations that can occur in the oral cavity. The aim of this study was to identify the main oral manifestations related to chikungunya fever, as well as describe the demographic characteristics of patients, by conducting a systematic review of the literature., Methods and Findings: Searches were performed in MEDLINE (PubMed), Embase (Elsevier), LILACS (VHL), Cochrane Library, Scopus, and CAPES electronic databases for theses and dissertations published up to January 16, 2021 without language and date restrictions. Additional manual searches of gray literature, reference list, and Google Scholar were carried out. We included 27 studies highlighting mainly oral manifestations that cause masticatory discomfort such as ulcers and oral thrush, gingival bleeding, pain and burning of the oral mucous membranes, temporomandibular joint (TMJ) arthralgia, opportunistic infections, and changes in taste., Conclusions: There seems to be a predominance of oral manifestations that cause discomfort when chewing, such as ulcerations in the acute phase of the disease, with complete remission within 3 to 10 days after the onset, apparently mostly affecting women and older persons. These oral manifestations can be compatible with basic viral infections related to inflammatory response and transitory immunosuppression., Competing Interests: The authors have declared that no competing interests exist.

Introduction: Extraintestinal manifestations (EIMs) are frequent in patients with inflammatory bowel disease (IBD). Our objective is to characterize and determine the prevalence of MEIs in our cohort of patients with IBD., Patients and Methods: A retrospective study was carried out in adult patients with IBD at the Pablo Tobón Uribe Hospital in Medellín. Colombia. Articular MEIs, primary sclerosing cholangitis (PSC), both ophthalmological and dermatological, were considered. Absolute and relative frequencies were used. The Chi square test of independence was used to compare 2proportions and the odds ratio (OR) was estimated., Results: Our registry has 759 patients with IBD, 544 present UC (71.6%), 200 CD (26.3%) and 15 unclassifiable IBD (1.9%); 177 patients with IBD (23.3%) presented EIMs, 123 of 544 (22.6%) with UC and 53 of 200 (26.5%) with CD (OR: 0.81, 95% CI: 0.55-1.17, P=0.31). Regarding the type of EIMs, the articular ones were the most frequent (13.5%), more in CD than in UC (20.0 vs. 11.3%, OR 1.94, 95% CI: 1.25-3.00, P=0.0037). Patients with IBD and EIMs used more antibodies against tumor necrosis factor (anti-TNFs), compared to those without EIMs (43.5 vs. 18.5%, OR 3.38, 95% CI: 2.31-4.90, P=0.0001)., Conclusions: The prevalence of EIMs in our cohort is high (23.3%) and the most frequent type is joint. Anti-TNFs are most used when IBD and EIMs coexist. Our study provides valuable information on the association of EIMs and IBD in Latin America., (Copyright © 2020 Elsevier España, S.L.U.

Introduction: the prevalence of denture related mucosa lesions (DRML) varies across different countries and a recent study reported an increasing trend in its prevalence. The objective of this study was to determine the prevalence of DRML and factors related to the lesions among denture wearers seen in a Nigerian teaching hospital., Methods: interviewer's administered questionnaire was used to obtain information from consecutive patients that had used removable denture for at least six months and consented to participate. Data related to gender, age, types of denture and presence of denture induced oral lesions were obtained, entered into a computer and analyzed using IBM SPSS Version 20. Descriptive statistics were expressed as frequency and percentages. Fisher's exact test was performed for discrete variables. A P-value less than 0.05 was regarded as statistically significant., Results: a total of 104 respondents participated in the study and 14 had DRML giving a prevalence of 13.5%. The majority, 11 out of the 14 (78.57%) presented with mucosa ulceration, while 8 (57.14%) out of the 14 cases of DRML were caused by over extension of the denture flanges. There was no statistically significant relationship between daily removal of denture fore going to bed to sleep at night and DRML (p=0.776)., Conclusion: the prevalence of denture related mucosal lesion was 13.3% and the major cause was over extension of denture flange. There is need to emphasize adherence to review appointments for early detection and correction of denture instability and over extension of denture flange to prevent DRML., Competing Interests: The authors declare no competing interests., (Copyright: Tunde Joshua Ogunrinde et al.)

A 23-year-old woman with autosomal dominant hyper-IgE syndrome complicated by recurrent pneumonia and sinusitis presented with 1 week of multiple painful oral ulcers unresponsive to empiric antiviral and antifungal treatment. Her ulcers progressively worsened and she required hospitalisation for intravenous hydration and pain control. PCR swab of an ulcer was positive for varicella-zoster virus. Her symptoms never fully resolved despite antiviral therapy, and within 2 weeks, she relapsed with new and worsening ulcers. Biopsy revealed chronic active inflammation with no evidence of viral inclusion bodies or fungal hyphae. She was diagnosed with recurrent aphthous stomatitis and referred to a local dentist for CO 2 laser treatments with rapid resolution of her symptoms. This case highlights the broad differential for recurrent oral ulcers in people with a primary immunodeficiency. It also raises awareness of the benefits of laser therapy for aphthous stomatitis treatment and the importance of partnering with our colleagues in dentistry., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Oral ulceration associated with bony exposure and sequestration is uncommon and often related to well-recognised conditions. In a small group of patients no obvious aetiological factors can be elucidated, and various terminologies have been utilised to describe these lesions. We report six cases of spontaneous oral ulceration with bone sequestration as a specific entity and review the pertinent literature. We retrospectively reviewed patients presenting in the period 2013-2018. Data collected included demographic details, relevant medical, drug, and radiotherapy history; presentation, investigations, management, and outcome. Six patients with an age range of 49-65 years were identified with spontaneous oral ulceration with bone sequestration in the study period. All were males, and none had any relevant history. Five lesions occurred over the mylohyoid ridge and one was related to a lingual mandibular torus. The most common presentation was a painful ulcer with exposed bone, which had been present for 6 - 12 weeks. Occlusal radiographs demonstrated focal rarefaction in two patients. All were managed conservatively and by removal of the loose sequestrum. Healing occurred successfully in all cases, and this was earlier when the loose sequestrum was removed. Spontaneous oral ulceration with bone sequestration is a distinct lesion that most often presents over the prominence of the mylohyoid ridge. It is currently an uncommon entity (0.02%), but this could well be due to a lack of recognition and under-reporting. It should be considered as a diagnosis only when other causes have been excluded. Lesions heal successfully with conservative management and surgical intervention, and this occurs earlier following removal of the loose sequestrum., (Copyright © 2020 The British Association of Oral and Maxillofacial Surgeons.

Topical interventions to treat oral ulcers in Behçet's disease (BD) are crucial to control disease activity and improve patients' quality of life. Our aim was to evaluate the effectiveness of a new BD mouthwash (BD MW) for oral ulceration. A retrospective cross-sectional study was carried out on 261 BD patients (141 women, mean (SD) age 39.9 (11.8) years, and 120 men, mean (SD) age 41.141(3.7) years). All were assessed using the oral ulcer severity score (OUSS), oral health quality of life (OHQoL), and the Behçet's disease current activity form (BDCAF). Patients were divided into three groups: one group used the BD MW, one group used a betamethasone mouthwash, and the other used no therapeutic mouthwash. Patients were assessed at three and six months. The OUSS in those using the BD MW was nine times lower than it was in those using betamethasone mouthwash (p=0.001), and 12 times lower than it was in the no mouthwash group (p=0.001). Compared with the baseline data, use of the BD MW during the first three months significantly reduced the OUSS, the BDCAF score, and intraoral scarring, and also improved OHQoL (p=0.001, 0.019, 0.012, and 0.001, respectively). Ongoing use of the BD MW after six months significantly improved the OUSS, OHQoL, and intraoral scars, and kept oral and systemic disease activity under control. A total of 20/31 patients reported high levels of satisfaction with its use, and a patients' satisfaction score showed a preference for it. This study confirms the efficacy of the BD MW in patients with recurrent oral ulceration (ROU). It is more efficacious than betamethasone mouthwash used alone., (Copyright © 2020.

A variety of acute oral lesions may be encountered in the scope of dermatology. Oral lesions may be single or multiple; may arise secondary to infectious, immune, congenital, medication use, or idiopathic causes; and may take a variety of forms. A thorough evaluation of the oral cavity is required to assess patients with oral lesions. Affected patients may be monitored, treated, or referred to an appropriate specialist for further management as needed. Many acute oral lesions are self-limiting in nature and patients may require only assessment and reassurance. Several common acute oral lesions are discussed in this article., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2020 Elsevier Inc. All rights reserved.)
