Lingua geographica: Welche Krankheit ist das?

Die Lingua geographica oder benigne migratorische Glossitis ist eine besondere und eigentümliche Zungenerkrankung, die zu einem landkartenartigen Aussehen mit Atrophie der filiformen Papillen an verschiedenen Stellen der Zunge führt. Die Form der Läsionen ändert sich mit der Zeit. Die genaue Ätiologie ist nach wie vor unbekannt, allerdings wird ein Zusammenhang mit der lingualen Mikrobiota des Patienten vermutet. Auch auf eine Assoziation zwischen Lingua geographica und Psoriasis wird seit langem hingewiesen, und es bestehen histologische Ähnlichkeiten zwischen beiden. Neuere Erkenntnisse deuten zunehmend auf eine Beteiligung bestimmter oraler Bakterien hin. Im Folgenden werden diese Befunde anhand eines Überblicks über die aktuelle Literatur diskutiert.

Geographic tongue: What is this disease?

Geographic tongue or benign migratory glossitis, is a unique and peculiar tongue condition, producing a map-like appearance with filiform papillae atrophy, on different parts of the tongue. The lesions change in shape with time. The exact etiology remains unknown, although it has been suggested relating the lingual microbiota of a patient. The association between geographic tongue and psoriasis has long been pointed out, and histological similarities existed between both as well. Increasingly, recent findings suggest the involvement of certain oral bacteria. Here, we discuss these findings with an overview of the recent literature.

Lactobacillus treatment as adjuvant for geographic tongue and fissured tongue with gastritis: case report

Background

Geographic tongue and fissured tongue are both common oral mucous membrane diseases relatively. The treatment of this disease is typically causative therapy because of the unknown etiology, and other afflictions. Gastrointestinal disease is one of the factors that induce geographic tongue with a fissured tongue. As an adjuvant drug that can inhibit the growth of Helicobacter pylori, the most common pathogen of chronic gastritis, Lactobacillus is widely used in clinic. However, there are seldom studies about Lactobacillus used in the treatment of geographic tongue and fissured tongue. Therefore, this case we used typically causative therapy with Lactobacillus as adjuvant to treat patient with a geographic tongue and fissured tongue with gastrointestinal disease and explore the effectiveness for further application.

Case Description

A 33-year-old female patient presented with a geographic tongue and fissured tongue with dysgeusia. At the first visit, there were smooth red lesions on the back of the tongue with the hyperplasia of the surrounding filiform papilla. The cracks in the middle of the tongue had a crack of about 2.5 cm long and 0.8 cm deep, and 5-6 light cracks on the tip of the tongue. The patient reported a history of chronic gastritis for 1 year, often with soft stool and gastroesophageal reflux disease. We administered drug treatment, including sodium bicarbonate tablets, Kangfuxin solution, compound chlorhexidine solution, and stomatitis spray. In addition, we suggested the patient use a yogurt machine to make and drink fresh yogurt with Lactobacillus as adjuvant everyday day and suggested a daily regimen of a light diet with no stimulating food, regular work, and sufficient rest. Ten days after the first visit, the symptoms were obviously alleviated. Twenty days after the initial diagnosis, the geographic tongue lesions had disappeared and the cracks had basically healed. The patient reported that the gastric symptoms had improved, and there was no soft stool or stomach discomfort.

Conclusions

This study used Lactobacillus as the adjuvant with typically causative therapy in the treatment of geographic tongue and fissured tongue.

Ulcerative and Inflammatory Lesions of the Oral Mucosa

Ulcerated and inflammatory lesions of the oral mucosa are not rare. A detailed patient medical and social history including habits and abuses, as well as the duration, location, focality and presence, or lack of local and/or systemic symptoms is critical in establishing a proper diagnosis. This article discusses the clinical presentation, management, and histopathologic characteristics of a variety of ulcerative and inflammatory lesions seen in the oral cavity.

Stress as worsening of the signs and symptoms of the geographic tongue during the COVID-19 pandemic: a pilot study

BACKGROUND

Geographic Tongue (GT) is a benign inflammatory disorder of unknown etiology, which is characterized by the loss of epithelium due to the atrophy of filiform papillae. It usually occurs on the dorsum of the tongue and may extend to its lateral edges. It appears as an erythematous area surrounded by whitish and slightly elevated margins. In most cases, the condition is asymptomatic, although some individuals may report symptoms that include a burning sensation of the tongue.

OBJECTIVE

Assess whether there was a change in the clinical aspect of Geographic Tongue (GT) during the COVID-19 pandemic.

METHODS

Thirty-two participants were recruited from Dentistry School Universidade Federal Fluminense. Anamnesis and oral examination were performed to collect medical history. The participants were split into two groups: control group (no GT) n = 20 and test group (with GT) n = 12. In the second step, nine participants from a 12 (75%) of the test group were contacted by phone and answered a questionnaire about changes in the signs and symptoms of GT during the pandemic. The subjects were subdivided into two groups: GT with and without signs and symptoms exacerbation.

RESULTS

In the first phase of the research, no statistical difference between control and test groups was observed regarding clinical criteria such as age (p + 0.72), gender (p = 0.24), and systemic diseases (p = 0.58). In the second phase, there was a statistical difference between GT groups with or without symptom exacerbation in terms of age and stress as a factor of the oral symptoms (p = 0.3 and 0.2), respectively. Younger patients showed a worsening of the oral lesions related to GT (p = 0.3) and reported stress during the pandemic (p = 0.02).

CONCLUSION

Younger patients were more susceptible to stress and presented more exacerbation of the oral lesions related to GT.

Investigation of oral atopic diseases: Correlation between geographic tongue and fungiform papillary glossitis

INTRODUCTION

The correlation between oral lesions and atopy is not new, but few studies have investigated the prevalence of mucosal changes in diseases within the atopic spectrum, leading to conflicting data. Some studies found a possible relationship between geographic tongue, transient lingual papillitis and atopic diseases.

AIM

To investigate the frequency of geographic tongue and fungiform papillary glossitis in patients with atopic diseases, and its correlation with serum IgE levels and skin test results.

MATERIAL AND METHODS

The sample was comprised of participants with atopic diseases paired with participants who received negative puncture skin tests. All were submitted to stomatological and medical evaluations, prick test and oral cytopathological.

RESULTS

The female sex was more numerous in both groups. Mean age was 21 years. A total of 60 diagnoses of atopic diseases were obtained, with allergic rhinitis being the most prevalent. Fungiform papillary glossitis was the most frequent oral lesion in both groups, while geographic tongue was present in 2 cases (2%) in the test group and 2 (2%) in the control group. Atopic patients with fungiform papillary glossitis presented high serum IgE levels. In atopic patients with geographic tongue, the prick test positively identified extracts of Dermatophagoides pteronyssinus (100%) and Dermatophagoides farinae (100%).

CONCLUSION

Due to the low frequency of geographic tongue lesions found in the study, it is no possible to conclude if that could be an oral manifestation of atopy. However fungiform papillary glossitis is a common alteration in atopic and non-atopic patients and has a relationship with high IgE serum levels. However, the consolidation of this result requires a larger sample size.

Oral mucosal lesions in a COVID-19 patient: New signs or secondary manifestations?

Some oral manifestations have been observed in patients with coronavirus disease 2019 (COVID-19). However, there is still a question about whether these lesions are due to coronavirus infection or secondary manifestations resulting from the patient's systemic condition. Thus, this article aims to report an additional case of an oral condition in a patient diagnosed with COVID-19. Our patient, a sixty-seven-year-old Caucasian man, tested positive to coronavirus and presented oral manifestations such as recurrent herpes simplex, candidiasis, and geographic tongue. We support the argument that some oral conditions could be secondary to the deterioration of systemic health or due to treatments for COVID-19. The present case report highlights the importance of including dentists in the intensive care unit multi-professional team to improve oral health in critical patients, not only COVID-19 patients, but also, to contribute to evidence-based and decision-making in managing infectious diseases.

Photobiomodulation Effect of Low-level Laser Therapy as a Palliative Treatment of Symptomatic Geographic Tongue (A Double-blinded Randomized Clinical Trial)

AIM

To evaluate the effectiveness of photobiomodulation (PBM) of low-level laser therapy (LLLT) as a palliative treatment of symptomatic geographic tongue.

MATERIALS AND METHODS

This randomized double-blinded controlled clinical trial was performed on 50 patients with symptomatic geographic tongue (GT). Participants were allocated randomly into study and control groups. A 660-nm diode laser was applied on randomly selected patients of the study group (n = 25) over the complained site for 2 minutes with continuous laser beam application. For the control group (n = 25), no application of 660-nm diode laser was performed. None of the participants were aware if they received the LLLT or placebo treatment. Patients were assessed for the level of pain, burning sensation, and size of the lesion before starting LLLT "T0" and during recall visit "T1, T2, and T3."

RESULTS

The study group showed a low level of pain, burning sensation, and better healing with statistically significant differences at T2 and T3 of the follow-up period, with a level of significance was set at p < 0.05.

CONCLUSION

Low-level laser therapy can be used to adequately relieve significant discomforts associated with GT and accelerate healing and restoring of the patient's quality of life.

CLINICAL SIGNIFICANCE

To develop a framework based on the results regarding the photobiomodulation effect of a 660-nm diode laser to relieve pain and burning sensation associated with symptomatic GT, which increases patients' perception toward the services provided to them.

Treatment of symptomatic benign migratory glossitis: a systematic review

OBJECTIVE

The aim of this systematic review is to summarize the results of all published studies on symptomatic benign migratory glossitis and evaluate the best available treatment.

METHODS

We searched the Cochrane Library, EMBASE, LILACS, PubMed, Scopus, and Web of Science for articles published up to September 2017, with no time restriction. We considered only articles published in English that evaluated the treatment of symptomatic benign migratory glossitis in children and adults. The protocol for this systematic review was registered at the international prospective register of systematic reviews (PROSPERO) as CRD42017074096.

RESULTS

Of the 840 identified studies, 11 were included in our sample. Multiple treatment modalities were described for the treatment of symptomatic benign migratory glossitis.

CONCLUSIONS

There is a very low level of evidence for the treatment of symptomatic benign migratory glossitis, with substantial methodological heterogeneity among the evaluated studies. In summary, we could identify no specific treatment for symptomatic benign migratory glossitis.

CLINICAL RELEVANCE

In clinical practice, at the outpatient clinic of oral medicine, we attend to many patients diagnosed with benign migratory glossitis, with varying intensity of pain ranging from mild to severe. Treating this disease is a formidable challenge for clinicians. Therefore, we performed a systematic review of benign migratory glossitis to identify the best evidence-based treatment available for this condition. We believe that this article may be useful in guiding clinicians on the choice of treatment.

Digestive system in psoriasis: an update

Psoriasis is a chronic inflammatory immune-mediated disorder associated and often coexisting with many other immune-related clinical conditions including those affecting the gastrointestinal tract. Data obtained from the reviewed literature suggest an association between psoriasis and pathologies of the oral cavity, both psoriasis-specific lesions, as well as non-specific, such as geographic tongue or fissured tongue. These findings show the importance of thorough examination of oral mucosa in psoriatic patients. Inflammatory bowel diseases (IBD) are also linked with psoriasis. Crohn’s disease and ulcerative colitis share a common genetic background, inflammatory pathways and have an evident iatrogenic anti-TNF treatment link, necessitating dermatological or gastroenterological care in patients with IBD or psoriasis, respectively, as well as treatment adjusted to manifestations. The presence of celiac disease-specific antibodies in psoriatic patients and their correlation with the severity of the disease show the association between these disorders. The linking pathogenesis comprises vitamin D deficiency, immune pathway, genetic background and increase in the intestinal permeability, which suggests a potential benefit from gluten-free diet among psoriatic patients. The link between psoriasis and non-alcoholic fatty liver disease implies screening patients for components of metabolic syndrome and lifestyle changes necessity. Some studies indicate increased prevalence of cancer in patients with psoriasis, probably due to negative influence of skin lesion impact on lifestyle rather than the role of psoriasis in carcinogenesis. However, there are no sufficient data to exclude such an oncogenic hit, which is yet to be confirmed. Therefore, all psoriasis-associated comorbidities establish the importance of a multidisciplinary approach in the treatment of these patients.

Autoimmune Disease Manifestations in the Oral Cavity

Immune-related disorders of the oral cavity may occur as primary disease process, secondary to systemic disease or neoplasm, or as a reaction to medications and other agents. The entities represented within this group may vary significantly by severity, clinical presentation, microscopic presentation, and special testing results. The selected immune-related conditions of the oral cavity in this article are categorized and presented by their prototypical tissue reaction patterns: vesiculobullous, including acantholytic and subepithelial separation; psoriasiform; spongiotic; and lichenoid reaction patterns.

Unmet diagnostic needs in contact oral mucosal allergies

The oral mucosa including the lips is constantly exposed to several noxious stimuli, irritants and allergens. However, oral contact pathologies are not frequently seen because of the relative resistance of the oral mucosa to irritant agents and allergens due to anatomical and physiological factors. The spectrum of signs and symptoms of oral contact allergies (OCA) is broad and a large number of condition can be the clinical expression of OCA such as allergic contact stomatitis, allergic contact cheilitis, geographic tongue, oral lichenoid reactions, burning mouth syndrome. The main etiological factors causing OCA are dental materials, food and oral hygiene products, as they contain flavouring agents and preservatives. The personal medical history of the patient is helpful to perform a diagnosis, as a positive history for recent dental procedures. Sometimes histology is mandatory. When it cannot identify a direct cause of a substance, in both acute and chronic OCA, patch tests can play a pivotal role in the diagnosis. However, patch tests might have several pitfalls. Indeed, the presence of metal ions as haptens and specifically the differences in their concentrations in oral mucosa and in standard preparation for patch testing and in the differences in pH of the medium might result in either false positive/negative reactions or non-specific irritative reactions. Another limitation of patch test results is the difficulty to assess the clinical relevance of haptens contained in dental materials and only the removal of dental materials or the avoidance of other contactant and consequent improvement of the disease may demonstrate the haptens’ responsibility. In conclusion, the wide spectrum of clinical presentations, the broad range of materials and allergens which can cause it, the difficult interpretation of patch-test results, the clinical relevance assessment of haptens found positive at patch test are the main factors that make sometimes difficult the diagnosis and the management of OCA that requires an interdisciplinary approach to the patient.

[Melkersson Rosenthal syndrome. Report of two pediatric cases]

Melkersson Rosenthal syndrome is a very infrequent disease of unknown etiology, chronic and progressive course, with neurocutaneous disease that affects the orofacial innervation and mucocutaneous tissues with non-caseating granulomatous infiltration. Clinically, it is characterized by the diagnostic triad: recurrent edema of lips and/or face; recurrent and alternating acute peripheral facial paralysis and scrotal or geographic tongue. The condition generally presents as oligosymptomatic or monosymptomatic form. Two patients are presented with completed triad and oligosymptomatic form. This recent review published by G. Kayabasoglu et al. states that only 30 patients have been described in the international literature in childhood. So we consider this disease in the differential diagnosis in the presence of acute peripheral facial paralysis and/or lips or facial edema.

Unraveling oral psoriasis and its relationship with geographic tongue: A literature review

Differentiating between oral psoriasis and geographic tongue is difficult and controversial because some patients with geographic tongue do not necessarily have psoriasis. Furthermore, the number of clinical studies, reporting histopathological and genetic evidence for the definitive diagnosis of oral psoriasis, is limited. The aim of this literature review was to obtain data for supporting the diagnosis of oral psoriasis with particular emphasis on the relationship between psoriasis and geographic tongue. Based on the current data, it can be concluded that geographic tongue is the most common oral lesion in psoriasis, and histopathological, immunohistochemical, and genetic similarities have been observed between the two diseases. This review also emphasizes the importance of conducting oral examinations in patients with psoriasis and skin examinations in patients with geographic tongue.

Relation between psoriasis and geographic tongue

The aim this article is to investigate the link between geographic tongue and psoriasis skin disease. Our review paper of the literature will handle strict study about the relation between geographic tongue and psoriasis. Our search has identified only limited studies available in English written literature starting from 2006-2013 using pubMed - indexed for MEDLINE. The result of this review suggests that geographic tongue may be an oral manifestation of psoriasis.There is no clear evidence in literature about association with gender and aetiology except one study which shows that benign migratory glossitis is more prevalent in young, nonsmoker and atopic or allergic individuals. Treatment for oral lesions is not standardized. A geographic tongue is significantly more frequent in psoriatic patients but only a limited data is available to date to strongly validate the association between these two entities.We recommend the general practitioner to have a good understanding about the clinical presentation, pathogenesis, diagnosis and treatment of this lesion. Psoriatic patients should be encouraged to undergo routine dental checkups.

Geographic tongue in monozygotic twins

This article discusses a case of 5-year-old girl monozygotic twins who were suffering from geographic tongue (GT), a benign inflammatory disorder of the tongue which is characterized by circinate, irregular erythematous lesions on the dorsum and lateral borders of the tongue caused by loss of filiform papillae of the tongue epithelium. Whilst geographic tongue is a common entity, reports on this condition are uncommon in the literature. To best of our knowledge, this is the first report which has described monozygotic twins with geographic tongue in the literature.

Geographic Tongue and Associated Risk Factors among Iranian Dental Patients

BACKGROUND

Geographic Tongue is a benign disorder involving the dorsal surface of the tongue characterized by depapillated areas with leading and folded edges in yellowish or grayish white color and sometimes with unclear borders. Many studies have reported a relationship between such condition and different risk factors. This study aimed to investigate the prevalence rate and the risk factors of geographic tongue in the patients referring to the Department of Oral Medicine of Zahedan Dental School, in 2012.

METHODS

Using Poisson regression model, 2000 patients referred to the Department were selected for this cross-sectional study. Data collection method included an investigation into the medical history as well as doing intraoral examinations. Using SPSS 17 software and Chi-square statistical test, the collected data were analyzed.

RESULT

Among the 2000 patients selected, 7.8% (156 persons) suffered from geographic tongue. The results of our study show that there is a significant relationship between the occurrence of geographic tongue and a history of allergy and fissured tongue (P<0.001). There was no significant statistical relationship between the occurrence of geographic tongue and gender, smoking and medication.

CONCLUSION

The geographic tongue is more frequently in the patients suffering from atopy or allergy as well as the patients with fissured tongue.
