Unique Cytomegalovirus Tongue Ulcer in an Older Adult Patient with Prolonged Systemic Steroid Treatment

Introduction: Cytomegalovirus (CMV) is a member of the Herpesviridae family that infects humans. It infects approximately 90% of adults. It is an opportunistic pathogen, common among immunosuppressed patients and can affect multiple organs. To date, there has been only one reported case of a CMV-related tongue ulcer that occurred during steroid treatment. Case Presentation: We report a case of CMV tongue ulcer in an elder, immunodeficient patient under prolonged steroid treatment. Management and Prognosis: A 67-year-old man under chronic steroidal treatment due to severe chronic obstructive pulmonary disease (COPD), with chronic ischemic heart disease (CIHD) and poorly treated diabetes mellitus (DM) was hospitalized in Soroka university medical center. He suffered from an ulcerative wound about 10 mm in its greater diameter with raised margins on the left lateral tongue. Daktarin Oral Gel treatment showed no improvement. On histopathological examination, a diagnosis of CMV-related tongue ulcer was given. Conclusion: To the best of our knowledge, this is the most detailed case report of CMV tongue ulcer due to prolonged steroid treatment. An early diagnosis of CMV infection in patients with oral lesions is crucial because CMV infection can increase immunosuppression, and is associated with opportunistic infections.

Objective To investigate the clinical efficacy of Kangfuxin solution combined with lidocaine and gentamicin in the treatment of oral ulcers. Method A total of 120 patients with oral ulcer admitted to Tongzhou District Maternity and Child Health Care Hospital of Beijing from May 2019 to July 2021 were selected and divided into observation group and control group randomly. 58 patients were treated with lidocaine as a control group and 62 patients in the observation group were treated with Kangfuxin solution combined with lidocaine and gentamicin. The clinical efficacy, including oral ulcer condition, visual analogue scale (VAS score) after 3d and 5d of treatment, inflammatory factor levels and adverse reactions were observed and compared between the two groups before and after treatment. Results The overall effective rate of the treatment group (95.12%) was higher than that of the control group (74.36%) and the difference was statistically significant (P<0.05). The ulcer area, ulcer healing time, and chewing improvement period were remarkably reduced compared with those in the control group (P<0.05). The VAS scores after 3d and 5d of treatment, the levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) and interleukin-6 (IL-6) between the two groups were statistically significant (P<0.05). There was no significant difference in the incidence of adverse reactions (3.22%) between the observation group and the control group (6.90%) (P>0.05). Conclusion Kangfuxin solution combined with lidocaine and gentamicin showed better curative effect on oral ulcer. This treatment regimen could effectively ameliorate various clinical symptoms of patients with oral ulcer, reduce patient pain and downregulate the levels of inflammatory factors, and help patients recover with high safety profile.

Effects of honey-lemon spray on recurrent aphthous stomatitis comparing to Triamcinolone ointment: a randomized controlled clinical trial

Recurrent aphthous stomatitis (RAS) is recurrent and painful diseases of the oral mucosa that can be very painful and annoying despite their small size. There is no definitive cure for this disease and the usual treatments are mainly based on pain control. The aim of this study was to investigate the effect of honey-lemon spray (mucotin) in the treatment of recurrent aphthous stomatitis. Methods: This study is a randomized controlled clinical trial conducted in 2020 at Zahedan University of Medical Sciences on 46 RAS patients. The participants were randomly assigned to the intervention (mucotin) or control groups (Triamcinolone ointment) equally (23 patients in each group). Patients were evaluated for the severity of pain and ulcer size. Evaluations were performed on days 0, 2, 7 of the treatment using VAS. Data were analyzed using ANOVA statistical test. Results: The inner aspect of the lower lip was the most common site of RAS in the participants (48.8%) and the lowest site went for hard palate (2.4%). Four items including pain, burning sensation, necrosis area, and erythematous area were evaluated in both groups. There was no significant difference in all parameters before the treatment period (day 0). The mean pain score, burning sensation, necrosis, erythematous areas were not different in days 0, 2 and 7 between groups respectively (p=0.849, p=0.105, p=0.917, p=0.442). Conclusion: Honey-lemon spray (Mucotin) and topical corticosteroid have similar effects in RAS treating, So Mucotin can be used as the first line of treatment for RAS lesions. This herbal medicine has no side effects

Enfrentamiento de lesiones de cavidad oral: clasificación y diagnóstico diferencial / Assessment of oral cavity lesions: classification and differential diagnosis

Las lesiones de la cavidad oral corresponden a un hallazgo frecuente y muchas veces difíciles de diagnosticar. Su correcto reconocimiento podría ser clave en detectar patologías que podrían cambiar el pronóstico del paciente. El objetivo de esta revisión es describir una clasificación de las lesiones de la cavidad oral que permita ayudar al diagnóstico en la práctica clínica. Para esto, se detallan y se describen las lesiones, orientando al diagnóstico y a la necesidad de biopsiar. Para simplificar la orientación diagnóstica, las lesiones se clasifican en 2 grandes grupos: tumorales y no tumorales. Las lesiones no tumorales se subdividen en lesiones de la mucosa oral y lesiones de la lengua.

Lesions of the oral cavity are frequent and often difficult to diagnose. However, correct recognition could change the patient's prognosis. This review aims to describe a classification of oral mucosa lesions, to help the diagnosis in clinical practice. The lesions are described for this, guiding the diagnosis and the need for biopsy. To simplify the diagnostic orientation, the lesions are classified into two groups: tumor and non-tumor lesions. Non-tumor lesions are subdivided into lesions of the oral mucosa and lesions of the tongue.

Soluble epoxide hydrolase inhibitor promotes the healing of oral ulcers

Abstract Objective Oral ulcers are a lesion in the oral mucosa that impacts chewing or drinking. Epoxyeicosatrienoic Acids (EETs) have enhanced angiogenic, regenerative, anti-inflammatory, and analgesic effects. The present study aims to evaluate the effects of 1-Trifluoromethoxyphenyl-3-(1-Propionylpiperidin-4-yl) Urea (TPPU), a soluble epoxide hydrolase inhibitor for increasing EETs level, on the healing of oral ulcers. Methods The chemically-induced oral ulcers were established in Sprague Dawley rats. The ulcer area was treated with TPPU to evaluate the healing time and pain threshold of ulcers. The expression of angiogenesis and cell proliferation-related protein in the ulcer area was detected using immunohistochemical staining. The effects of TPPU on migration and angiogenesis capability were measured with scratch assay and tube formation. Results Compared with the control group, TPPU promoted wound healing of oral ulcers with a shorter healing time, and raised pain thresholds. Immunohistochemical staining showed that TPPU increased the expression of angiogenesis and cell proliferation-related protein with reduced inflammatory cell infiltration in the ulcer area. TPPU enhanced cell migration and tube-forming potential in vitro. Conclusions The present results support the potential of TPPU with multiple biological effects for the treatment of oral ulcers by targeting soluble epoxide hydrolase.

Una mirada al tratamiento actual de la estomatitis aftosa recurrente. Revisión de la literatura / A look at the current management of recurrent aphthous stomatitis: scoping review

Resumen La estomatitis aftosa recurrente (EAR) es una patología ulcerativa crónica idiopática, que, aunque no llega a comprometer la vida de los pacientes, si puede desmejorar su calidad de vida. Presenta una alta incidencia en la población con un alto porcentaje de recurrencia. Atendiendo a su importancia, el objetivo de esta revisión es brindar una actualización respecto a las terapias farmacológicas y con láser para el manejo de la estomatitis aftosa recurrente. Se realizó una búsqueda bibliográfica en las bases de datos PubMed, Science Direct, EBSCO HOST y LILACS desde enero de 2010 a octubre de 2020, identificando publicaciones en inglés y español. Los artículos que fueron incluidos debían estar relacionadas con la estomatitis aftosa y su tratamiento, enfocándose en el manejo farmacológico o con láser. La estrategia de búsqueda arrojó 4536 citas bibliográficas, de las cuales fueron incluidas 19 en esta presente revisión. La mayoría de los estudios fueron ensayos clínicos aleatorizados donde la población objeto fueron adultos que demostraron el uso de antiinflamatorios, inmunomoduladores, anticuerpos monoclonales, antisépticos, anestésicos, entre otros, para el manejo de la estomatitis aftosa recurrente. De los artículos analizados se pudo concluir que la terapia farmacológica debe ser instaurada de manera particular, de acuerdo a la clínica y antecedentes del paciente. Los fármacos de primera elección son de uso tópico, reservando los de uso sistémico para casos moderados o severos y para pacientes con tratamiento refractarios, asimismo, las recomendaciones coadyuvantes como alimentación e higiene pueden ayudar a la resolución de la enfermedad. La terapia láser surge como alternativa de tratamiento con bajo riesgo y buenos resultados para la EAR.

Abstract Recurrent Aphthous Stomatitis (RAS) is an idiopathic chronic ulcerative pathology. Although it does not compromise the life of the patients, it can impair their quality of life. It presents a high incidence in the population and a high percentage of recurrence. In view of its importance, the aim of this review is to provide an update on pharmacological and laser therapies that are being implemented for the management of RAS. A bibliographic search of literature that was published between January 2010 and October 2020 was performed in PubMed, Science Direct, EBSCOhost, and LILACS databases, identifying publications in English and Spanish languages. The articles that were included had to be related to aphthous stomatitis and its treatment, focusing on pharmacological or laser management. 4536 bibliographic citations were found and 19 of them were included in this review. Most of the studies were randomized clinical trials in which the target population were adults that reported the use of anti-inflammatory drugs, immunomodulators, monoclonal antibodies, antiseptics, anesthetics, among others for the treatment of recurrent aphthous stomatitis. From the articles analyzed, it was possible to conclude that pharmacological therapy should be established in a particular way according to the patient's symptoms and medical record. The first-choice drugs are of topical use, reserving those of systemic use for moderate or severe cases and for patients with refractory treatment. Likewise, adjuvant recommendations such as nutrition and hygiene can help in the resolution of the disease. Laser therapy emerges as an alternative treatment with low risk and positive results for recurrent aphthous stomatitis.

Facial Palsy with Tongue Ulcer: A Rare Initial Presentation of Granulomatosis with Polyangiitis

ABSTRACT@#Granulomatosis with polyangiitis (GPA) is a rare multisystem disease. Although GPA is rare, it commonly presents in a localised stage where its manifestation involves the upper or lower respiratory tract before progressing to a generalised stage. Therefore, most patients with GPA will visit an oral surgeon or an otolaryngologist to seek treatment. However, the diagnosis of GPA is often delayed as GPA is not frequently considered as a differential diagnosis in common oral and facial diseases. The lack of gold standard investigation for the diagnosis of GPA makes management of this case, a diagnostic conundrum. We herein report a patient who was diagnosed with bilateral acute otitis media and left mastoiditis complicated with facial nerve palsy, and later developed tongue ulceration one month after his initial presentation. The ear, facial and oral symptoms represent a diagnostic red herring to a full-blown generalised stage of GPA.

Clinical assessment of the oral cavity was performed on the 2 nd and 5 th days of orotracheal intubation. Thirty-eight patients were evaluated and 16 (42.1%) presented oral lesions during their ICU stay. The median age and length of stay were 75 years and 15 days, respectively. Among the patients with oral lesions, ulcerative oral lesions were reported in 14 (87.5%) patients, of which 11 (78.6%) were found on the lips. This study highlights the importance of oral examination for patients admitted to the ICU with COVID-19.

Oral ulcers and sarcoid-like reaction in lymph nodes after cemiplimab therapy for locally advanced cutaneous squamous cell carcinoma: a case report

ABSTRACT Cemiplimab is a novel programmed death-1 inhibitor recently approved for advanced cutaneous squamous cell carcinoma. Immune-related adverse events derived from cemiplimab are similar to other anti-PD-1 drugs, including gastrointestinal and cutaneous toxicities. Oral immune-related adverse events were not reported with cemiplimab in previous studies; thus this case report warns of the fact that the oral cavity may be a site of immune-related adverse events during programmed death-1 block therapy and that this can lead to significant limitations when not properly treated. The present report describes the case of a patient with locally advanced cutaneous squamous cell carcinoma metastatic to cervical lymph nodes who developed dysphagia due to large and painful oral ulcers after a single dose of cemiplimab. The patient also exhibited a sarcoid-like reaction in mediastinal lymph nodes. No immune-related adverse events were found in any other organs. The oral lesions showed significant improvement after topical and short-course systemic corticosteroids, and low-level laser therapy was also performed in the oral lesions. The patient achieved a near-complete response and treatment was discontinued. This article discusses in detail the clinical outcomes and oral toxicity management of cemiplimab therapy for cutaneous squamous cell carcinoma.

Síndrome de Behçet ou úlcera de Lipschütz: desafio diagnóstico / Behçet's syndrome or Lipschütz ulcer: diagnostic challenge

A ocorrência de úlceras genitais em adolescentes e mulheres jovens tem impacto emocional para as pacientes e seus familiares, pela frequente associação com uma possível etiologia de transmissão sexual. Porém, úlcera de Lipschütz e síndrome de Behçet não têm etiologia infecciosa e devem ser lembradas como possíveis diagnósticos diferenciais. O diagnóstico dessas duas patologias é clínico e pode ser desafiador. Dessa forma, foi realizada uma revisão na literatura com o objetivo de comparar as duas entidades. A úlcera de Lipschütz é causada por uma vasculite local e caracteriza-se pelo surgimento súbito de úlceras na vulva ou vagina inferior. Já a doença de Behçet é causada por vasculite sistêmica, com episódios de remissão e exacerbação, que pode envolver quase todos os sistemas orgânicos. Em ambos os casos, é essencial o referenciamento para reumatologia. O tratamento objetiva suprimir exacerbações, controlar a dor e prevenir infecção secundária.(AU)

The occurrence of genital ulcers in adolescents and young women have an emotional impact for the patient and their families, due to the frequent association of its etiology with a sexually transmitted disease. However, Lipschütz ulcer and Behçet's syndrome do not have an infectious etiology and should be remembered as a possible differential diagnoses. As the diagnosis of these two pathologies is clinical and can be challenging, a review of literature was carried out. The objective of this review of literature was to compare both diseases. Lipschütz ulcer is caused by local vasculitis and is characterized by the sudden appearance of ulcers in the vulva or lower vagina. Behçet's syndrome is caused by systemic vasculitis, with episodes of remission and exacerbation, which can affect almost all organ systems. In both cases, referral to rheumatology is essential. Treatment aims to suppress exacerbations, control pain and prevent secondary infection.(AU)

Primary angiosarcoma of the oral cavity in a young adult

Angiosarcoma is a rare neoplasm, constituting only 2% of all the soft tissue tumors and most frequently involves the skin of the head and neck region in elderly males. They are extremely aggressive tumors with high rates of metastasis and poor outcomes. We report a unique case of angiosarcoma involving an unusual site - upper alveolus and maxilla in a young patient highlighting the diagnostic challenges in such a scenario. A 29 years old female presented with a non-healing wound of the oral cavity, which had progressed to the current maximum size of 6.4 cm within one month. Magnetic resonance imaging (MRI) scan revealed the involvement of maxilla up to the floor of the orbit and adjacent soft tissue. However, no distant metastasis was detected on Positron Emission Tomography (PET) scan. Biopsy of the lesion showed an irregular, highly pleomorphic, and mitotically active epithelioid soft tissue tumor conclusively diagnosed as angiosarcoma.

Combined application of montmorillonite powder and Kangfuxin liquid for the treatment of stomatitis complicated by oral ulcer in 62 patients / 中国基层医药

Objective:To investigate the clinical application value of montmorillonite powder combined with Kangfuxin liquid in the treatment of stomatitis complicated by oral ulcer. Methods:A total of 124 patients with stomatitis complicated by oral ulcer who received treatment in Zhoushan Women and Children Hospital, China between January 2019 and October 2020 were included in this study. They were randomly assigned to receive treatment either with montmorillonite powder alone (control group, n = 62) or montmorillonite powder and Kangfuxin liquid (observation group, n = 62). Visual Analogue Scale score before and after treatment, duration of ulcer pain and wound recovery time, curative effect and adverse reactions were compared between the two groups. Results:After treatment, Visual Analogue Scale score in each group was significantly decreased compared with before treatment ( t = 5.862, 8.223, both P < 0.05). After treatment, Visual Analogue Scale score in the observation group was significantly lower than that in the control group [(0.72 ± 0.23) points vs. (1.22 ± 0.47) points, t = 2.667, P < 0.05]. The time to ulcer pain relief and the time to wound recovery in the observation group were significantly shorter than those in the control group ( t = 3.467, 2.667, both P < 0.05). Effective rate in the observation group was significantly higher than that in the control group [96.77% (60/62) vs. 85.48% (53/62), χ2 = 4.888, P < 0.05]. There were no adverse reactions in each group. Conclusion:Combined application of montmorillonite powder and Kangfuxin liquid for the treatment of stomatitis complicated by oral ulcer can effectively mitigate wound pain, accelerate wound healing, and improve the quality of life. This study is of significant innovation and science. Therefore, the treatment method used in this study is worthy of clinical promotion.

Research progress on the role of T helper cells 17 and interleukin 17 in oral mucosal diseases / 口腔疾病防治

@#T helper 17 (Th17) cells are a new type of CD4+ T helper cell. They participate in the immune and inflammatory response by secreting specific interleukin-17 (IL-17). In oral mucosal diseases, oral lichen planus (OLP), recurrent aphthous ulcer (RAU) and Behcet′s disease (BD) are associated with Th17 cells and IL-17. There were 17 kinds of proteins in the saliva of patients with OLP that could upregulate the expression of Th17 cells and induce the secretion of IL-17. IL-17 can stimulate epithelial cells, endothelial cells and fibroblasts to produce a variety of cytokines, such as IL-6, IL-8, granulocyte macrophage colony-stimulating factor and cell adhesion molecule-1, leading to the production and aggravation of inflammation. Th17/Tc17 cell-targeted therapy can significantly improve the clinical symptoms of OLP patients′ mucosa and skin. IL-17 can stimulate oral keratinocytes through the IL-17RA or IL-17RE receptor and produce proinflammatory effects in RAU. Th17 cells in the peripheral blood of BD patients are significantly increased, while Treg cells are significantly decreased.

Ulceración por trauma crónico: una lesión simuladora. Informe de un caso clínico / Oral traumatic ulceration: a mimic lesion. Report of a case

Objetivo: Describir la importancia del reconocimiento oportuno del trauma crónico de la mucosa bucal producido por un elemento dentario que generó una lesión erróneamente diagnosticada como neoplasia maligna. Caso clínico: Una paciente de sexo femenino, de 79 años de edad, realizó una consulta estomatológica por una lesión lingual con un diagnóstico presuntivo de cáncer. Tras la inspección de la cavidad bucal y el estudio anatomopatológico se diagnosticó úlcera asociada a trauma dentario. La intervención terapéutica odontológica (eliminación del trauma) resolvió el cuadro cínico. Conclusión: El trauma crónico en la mucosa bucal puede generar lesiones sobre mucosa sana o bien complicar una patología preexistente. En el presente caso, la inspección de la cavidad bucal con la identificación y la eliminación del trauma lograron la reparación de la lesión. El estudio anatomopatológico precisó el diagnóstico de ulceración asociada a trauma dentario (AU)

Aim: The aim of this case report is to show the importance of the early diagnosis of a traumatic lesion of the oral mucosa arising from a posterior broken tooth that was initially misdiagnosed as oral cancer. Case report: A 79-year-old female attends an appointment with the oral medicine specialist for a lesion on the lateral side of the tongue with a presumptive diagnosis of oral cancer. The examination of the oral cavity and the anatomopathological diagnosis confirmed the presence of an ulcer associated with dental trauma. The lesion healed completely with the elimination of the trauma. Conclusion: Chronic trauma in the oral cavity can produce lesions in the oral mucosa or exacerbate preexisting lesions. In this case report a thorough oral examination showed a broken tooth as the cause of trauma and after its removal the lesion healed completely. The result of the biopsy confirmed the diagnosis of an oral ulcer associated with dental trauma (AU)

Hyaluronic acid versus dexamethasone for the treatment of recurrent aphthous stomatitis in children: efficacy and safety analysis

The objective of this study was to compare the safety and efficacy of 0.2% hyaluronic acid (HA) topical gel and dexamethasone topical ointment in the treatment of recurrent aphthous ulcers (RAU) in children. This retrospective observational study included 104 patients who had more than two episodes of oral aphthous ulcers per year and were treated with HA (n=52) or dexamethasone (n=52) from August 15, 2014 to September 3, 2018. Therapy efficacy was evaluated based on the ulcer size and pain score before versus 7 days after either therapy. The paired t-test, chi-squared test, and independent t-test were utilized for statistical analyses. There was no significant difference in ulcer size or pain score between the HA and dexamethasone groups, on day 1 or day 7. Both treatments were tolerated well and no side effects were reported. No significant differences in body temperature, respiration rate, pulse, or systolic/diastolic blood pressure were observed between the start (day 1) and end of treatment (day 7), for either treatment. HA and dexamethasone showed similar efficacy in reducing ulcer size and pain scores, and were tolerated equally well in children with RAU. Future high-quality studies with larger numbers of patients are needed to confirm our findings.
