B12 deficiency-related glossitis is highly associated with high gastrin-17 and low pepsinogen I.

BACKGROUND: The causes of vitamin B12 (B12) deficiency are varied and mainly related to gastric disorders. Glossitis is a common oral manifestation of B12 deficiency and is often first seen by dentists. This study aimed to investigate the correlation between B12 deficiency-related glossitis (B12-def glossitis) and gastric serum biomarkers [gastrin-17(G17), pepsinogen I (PGI), pepsinogen II (PGII), and anti-Helicobacter pylori (H. pylori) antibodies], and preliminarily discuss the etiology of B12-def glossitis. METHODS: A cross-sectional study was conducted in patients complaining of glossodynia, burning sensation, or severe recurrent oral ulcers, but patients with a history of gastrectomy were excluded. All subjects underwent a uniform oral examination and hematological tests. RESULTS: Of 243 patients, 133 with B12-def glossitis were in the case group, and 110 with other oral mucosal diseases (non-glossitis) and normal B12 levels were in the control group. In the case group, 84.2% (112/133) showed high G17 and low PGI levels (G17hi PGIlow ). Univariate logistic regression showed that G17hi PGIlow was a high-risk factor for B12-def glossitis (OR: 92.44; 95% CI: 35.91, 238.02). Subgroup analyses in the case group showed that the G17hi PGIlow group presented with lower B12 levels and a lower positive rate of anti-H. pylori antibodies compared to the non-G17hi PGIlow group. CONCLUSION: Gastric serum biomarkers in patients with B12-def glossitis generally showed G17hi PGIlow , suggesting possible atrophy of gastric corpus and fundus mucosa. The G17hi PGIlow and non-G17hi PGIlow groups may represent different etiologies of B12 deficiency.

Vitamin B12 deficiency may play an etiological role in atrophic glossitis and its grading: A clinical case-control study.

BACKGROUND: Existing studies have reported the significant association between atrophic glossitis (AG) and hematinic deficiencies, including iron, folate and vitamin B12 deficiency. However, these findings were inconsistent. AG can be graded as partial or complete atrophy. It is still unclear whether hematinic deficiencies are associated with the grading of AG. METHODS: 236 AG patients and 208 sex- and age-matched healthy controls were enrolled in this study. Hematological tests including complete blood count, and serum levels of folate, ferritin and vitamin B12 were performed. The AG group was divided into those with partial AG and those with complete AG according to the extent of papillary atrophy. Statistical analysis was performed to assess whether hematinic deficiencies are risk factors for AG and its grading. RESULTS: Compared with the healthy controls, AG patients had significantly higher frequencies of vitamin B12 deficiency (68.22%), ferritin deficiency (13.98%) and anemia (21.61%). The differences in hematinic deficiencies and anemia between AG patients and healthy controls changed according to gender and age. The frequencies of serum vitamin B12 deficiency and anemia in the complete AG subgroup were significantly higher than those in the partial AG subgroup. Logistic regression analysis revealed that vitamin B12 deficiency and anemia were significantly correlated with AG and its grading. The AG patients with vitamin B12 deficiency responded well to supplement therapy. CONCLUSION: AG could be an important clinical indicator for potential vitamin B12 deficiency, especially when the degree of tongue atrophy more than 50% and complete atrophy. Vitamin B12 deficiency might play an etiological role in the development of AG.

Atrophic glossitis: Etiology, serum autoantibodies, anemia, hematinic deficiencies, hyperhomocysteinemia, and management.

Atrophic glossitis (AG) is characterized by the partial or complete absence of filiform papillae on the dorsal surface of the tongue. AG may reflect the significant deficiencies of some major nutrients including riboflavin, niacin, pyridoxine, vitamin B12, folic acid, iron, zinc, and vitamin E. Moreover, protein-calorie malnutrition, candidiasis, Helicobacter pylori colonization, xerostomia, and diabetes mellitus are also the etiologies of AG. Our previous study found the serum gastric parietal cell antibody (GPCA), thyroglobulin antibody (TGA), and thyroid microsomal antibody (TMA) positivities in 26.7%, 28.4%, and 29.8% of 1064 AG patients, respectively. We also found anemia, serum iron, vitamin B12, and folic acid deficiencies, and hyperhomocysteinemia in 19.0%, 16.9%, 5.3%, 2.3%, and 11.9% of 1064 AG patients, respectively. Moreover, GPCA-positive AG patients tended to have relatively higher frequencies of hemoglobin, iron, and vitamin B12 deficiencies and hyperhomocysteinemia than GPCA-negative AG patients. Supplementations with vitamin BC capsules plus corresponding deficient hematinics for those AG patients with hematinic deficiencies can achieve complete remission of oral symptoms and AG in some AG patients. Therefore, it is very important to examine the complete blood count, serum hematinic, homocysteine, and autoantibody levels in AG patients before we start to offer treatments for AG patients.

Goodness, gracious, great balls of fire: A case of transient lingual papillitis following consumption of an Atomic Fireball.

Transient lingual papillitis is a benign condition characterized by the inflammation of one or more fungiform papillae on the dorsolateral tongue. Although it is a common condition that affects more than half of the population, few cases have been reported in the dermatological literature. Therefore, it is a condition uncommonly recognized by dermatologists though it has a distinct clinical presentation that may be easily diagnosed by clinicians familiar with the entity. We report an interesting case of transient lingual papillitis in a 27 year-old healthy woman following the consumption of the hard candy, Atomic Fireball. We describe treatment and resolution of the condition, and its recurrence following re-exposure to the identified culprit. This report further reviews the literature to illustrate the clinical manifestations, etiology, differential diagnosis, course, and treatment of this condition.

Factors associated with the presence of atrophic tongue in patients with dry mouth.

PURPOSE: This study aimed to identify factors associated with atrophic tongue in patients with dry mouth. METHODS: Discriminant analysis was performed in 1265 patients with dry mouth to identify factors that might influence the risk of developing atrophic tongue. The dependent variable was the presence of atrophic tongue, while patient age, resting saliva flow rate, stimulated saliva flow rate and Candida colony-forming units (CFU) were used as the independent variables. RESULTS: The standardised linear discriminant coefficients showed that Candida CFU, stimulated saliva flow rate and age were significantly associated with the presence of atrophic tongue. The following linear discriminant function was obtained: z = 0.024 × age - 0.63 × (resting saliva flow rate) - 0.81 × (stimulated saliva flow rate) + 0.002 × Candida CFU - 0.611. CONCLUSION: High Candida CFU, low stimulated saliva flow rate and advanced age were identified as closely associated factors for the risk of development of atrophic tongue.

Dermatological findings of vitamin B12 deficiency and resolving time of these symptoms.

AIM: The mucocutaneous changes observed during vitamin B12 deficiency in children have been published only as case studies and small case series. In this study, we aimed to demonstrate the frequency of mucocutaneous changes (particularly hyperpigmentation) seen during vitamin B12 deficiency and resolving time of these symptoms with vitamin B12 treatment. MATERIAL AND METHODS: This prospective study was conducted at the pediatrics outpatient clinic of Harran and Yuzuncu Yil University Faculty of Medicine, among 57 patients, aged between 6 and 24 months, who were diagnosed with vitamin B12 deficiency following various examinations and tests. A detailed examination was performed in respect to skin and mucosal findings. Patients with vitamin B12 deficiency were administered intramuscular cyanocobalamin. Prospective examination was continued, and resolving time of symptoms after treatment was recorded. RESULTS: The mean age of the patients enrolled in the study was found to be 12.75 ± 4.75. Hyperpigmentation was reported in 49 (85.96%) patients enrolled in the study; atrophic glossitis in 40 (70.17%), brittle and matt hair in 13 (22.80%), skin lesions (particularly diaper dermatitis) in eight (15.78%) and cheilosis in four (7.01%) patients. Three months after the treatment initiation, hyperpigmentation improved in 87.75%, atrophic glossitis in 97.5% and brittle and matt hair in 92.3% of the patients. Five patients (8.77%) with continuing pigmentation by the end of sixth months were considered as nonresponsive to the treatment. CONCLUSION: Deficiency of vitamin B12 should be considered in the differential diagnosis of infants who present with skin and mucosal lesions.

The role of unfinished root canal treatment in odontogenic maxillofacial infections requiring hospital care.

OBJECTIVES: The aim of this study was to evaluate clinical and radiological findings and the role of periapical infection and antecedent dental treatment of infected focus teeth in odontogenic maxillofacial abscesses requiring hospital care. MATERIALS AND METHODS: In this retrospective cohort study, we evaluated medical records and panoramic radiographs during the hospital stay of patients (n = 60) admitted due to odontogenic maxillofacial infection originating from periapical periodontitis. RESULTS: Twenty-three (38 %) patients had received endodontic treatment and ten (17 %) other acute dental treatment. Twenty-seven (45 %) had not visited the dentist in the near past. Median age of the patients was 45 (range 20-88) years and 60 % were males. Unfinished root canal treatment (RCT) was the major risk factor for hospitalisation in 16 (27 %) of the 60 cases (p = .0065). Completed RCT was the source only in 7 (12 %) of the 60 cases. Two of these RCTs were adequate and five inadequate. CONCLUSIONS: The initiation of inadequate or incomplete primary RCT of acute periapical periodontitis appears to open a risk window for locally invasive spread of infection with local abscess formation and systemic symptoms. Thereafter, the quality of the completed RCT appears to have minor impact. However, a considerable proportion of the patients had not received any dental treatment confirming the importance of good dental health. Thus, thorough canal debridement during the first session is essential for minimising the risk for spread of infection in addition to incision and drainage of the abscess. If this cannot be achieved, tooth extraction should be considered. CLINICAL RELEVANCE: Incomplete or inadequate canal debridement and drainage of the abscess may increase the risk for spread of endodontic infection.

Oral manifestations and blood profile in patients with thalassemia trait.

BACKGROUND/PURPOSE: Patients with thalassemia trait (TT) may have anemia. This study evaluated whether TT patients had specific oral manifestations and a particular blood profile compared with normal individuals. METHODS: The oral manifestations and mean red blood cell count, corpuscular cell volume, red blood cell distribution width, Mentzer index, and Green and King index as well as blood concentrations of hemoglobin, iron, total iron binding capacity, vitamin B12, folic acid, and homocysteine in 65 TT patients and in 130 age- and sex-matched healthy controls were measured and compared. RESULTS: TT patients had significantly higher frequencies of all oral manifestations than healthy controls (p < 0.001 for all), in which burning sensation of oral mucosa (90.8%), lingual varicosity (90.8%), dry mouth (72.3%), atrophic glossitis (32.3%), and numbness of the oral mucosa (30.8%) were the five leading oral manifestations for TT patients. Moreover, TT patients had significantly lower mean hemoglobin level, corpuscular cell volume, Mentzer index, and Green and King index (p < 0.001 for all) as well as significantly higher mean red blood cell count and red blood cell distribution width (p < 0.001 for both) than healthy controls. However, no significant difference in the mean blood iron, total iron binding capacity, vitamin B12, folic acid, or homocysteine levels was discovered between 65 TT patients and 130 healthy controls. CONCLUSION: TT patients have specific oral manifestations and a particular blood profile compared to normal individuals.

An apple a day ... chronic glossitis in a 4-year-old boy.

We report a case of chronic glossitis in a 4-year-old boy due to scurvy. The boy showed up in our department with a patchy depapillated tongue. A detailed dietary history revealed an unbalanced diet without any fruit or vegetable. The biological investigations showed a low serum ascorbic acid. The boy was treated by oral ascorbic acid during 15 days. The glossitis improved within one week and serum levels of vitamin C returned to the normal range. In industrial countries, scurvy became a rare disease in healthy children. However, since a few years, cases are reported in children and teenagers with unbalanced diet coming from economically favoured families. These extreme cases are one of the signs of a more general deterioration of dietary habits in paediatric populations in our societies. This emphasizes the importance of effective nutritional education programs aimed towards both parents and children.

Unusual Case of Painful Glossitis and Xerostomia Following Vaccination with Pfizer-BioNTech SARS-CoV-2 (BNT162b2).

BACKGROUND Adverse events following immunization (AEFIs) remain under recognized, particularly when the symptoms experienced are uncommon and mimic natural disease. In the context of the worldwide effort to provide protection against SARS-CoV-2 using multiple doses of vaccination and with the availability of multiple vaccines, the early recognition and prompt treatment of AEFIs has increased importance, as does the ability to carefully select an alternative after an AEFI occurs. CASE REPORT A 60-year-old woman presented for clinical immunology review with a 9-month history of glossitis and xerostomia. Onset of symptoms occurred following her first vaccination with a COVID-19 vaccine (BNT162b2). After partial interval improvement, her symptoms progressively worsened after a second vaccination and third booster vaccination with BNT162b2. While undergoing reviews from multiple specialists for possible underlying connective tissue disease, and with other causes of her symptoms being excluded, the patient's symptoms progressed, with worsening tongue swelling with new fissuring and xerostomia. The patient experienced an unintentional weight loss of 8 kg due to oral discomfort. It was only after this time that an AEFI was considered the cause of her presentation, after all other diagnostic considerations were considered unlikely. Targeted, symptomatic, localized treatment with topical oral corticosteroids was initiated, followed by a gradual tapering regimen, with excellent response. CONCLUSIONS This case highlights the need to consider AEFIs early in the differential diagnosis of unusual presentations and the importance of considering a trial of targeted symptomatic treatment for patients, even if diagnostic uncertainty remains.

Association of Severe Tongue Edema With Prone Positioning in Patients Intubated for COVID-19.

OBJECTIVES/HYPOTHESIS: Prone positioning is frequently used in patients intubated for COVID-19-related lung injury to improve oxygenation. At our institution, we observed severe tongue edema develop in some of these patients. Hence, we sought to determine the incidence of tongue edema in this cohort and whether prone positioning was a risk factor associated with this complication. STUDY DESIGN: Retrospective cohort study. METHODS: A single-system retrospective cohort study of patients intubated for respiratory failure secondary to COVID-19 who subsequently developed clinically notable tongue edema from March 13 to July 5, 2020. RESULTS: 260 patients were intubated for COVID-19-related respiratory failure during the study period. 158 patients (60.8%) underwent at least one episode of proning. Twelve patients in total (4.6%) developed clinically significant tongue edema. Eleven of the twelve patients (91.7%) who developed tongue edema underwent proning prior to the development of edema. Prone positioning was associated with an increased incidence of tongue edema (odds ratio [OR] 7.56, 95% confidence interval [CI] 0.96-59.46, P = .027). In all proned patients who developed edema, this complication was noted during proning or shortly after supination (range, 0-4 days). Tongue edema was primarily managed with conservative measures; one patient required tracheostomy for definitive management. CONCLUSIONS: Tongue edema appears to develop in a subset of patients with COVID-19 who are intubated. It appears to be associated with prone positioning but is likely multifactorial in nature. Further investigation into its incidence and pathophysiology is warranted. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:287-289, 2022.

The development and inflammatory features of radiotherapy-induced glossitis in rats.

OBJECTIVES: To improve the existing animal models (mice, rats, and hamsters) for radiotherapy-induced oral mucositis (RTOM), thereby establishing a radiotherapy-induced glossitis (RTG) Sprague-Dawley (SD) rat model. STUDY DESIGN: A lead device was designed to limit radiation exposure to a 1x1 cm2 area of a rat 's dorsal anterior tongue with a single 30 Gy of X-ray radiation. The general conditions of the irradiated rats, such as body-weight and behavior, were observed. The oral mucositis index (OMI) of the RTG rats were measured daily. Histological changes of the irradiated tongue tissues were assayed by H &E staining. RESULTS AND CONCLUSION: No significant changes were clinically observed 3 to 4 days after irradiation. At 5 to 6 day, punctuation and confluenced redness of the mucosa were observed. The small blood vessels became more extensive, engorged, thin vessel walls. More infiltrating cells were observable, necrosis and exfoliation of the squamous cells appeared, and the formation of an ulcerative lesion could be observed. Seven to 15 days, the exfoliated epithelial layer was observed to have formed an ulcerative lesion, then aggravated ulcerative lesions consisting of pseudomembranous filament exudates could be observed. The structure of the epithelium had become completely disintegrated, forming deep, microscopic ulcerative lesions. Twenty-one days, the periphery of the ulcer was observed to have begun to heal, and granulation tissue could be observed at the bottom of the ulceration. At 35 days after irradiation, the epithelial structure presented again, but the epithelium was very thin. An RTG animal model was successfully established in SD rats, which provides a new research platform for the study of RTOM pathogenesis.

The correlation between the severity of radiotherapy-induced glossitis and endothelial cell injury in local tissues in a rat model.

OBJECTIVES: To explore the correlation between the severity of radiotherapy-induced glossitis (RTG) and endothelial cell injury in local tissues in a rat model. STUDY DESIGN: The RTG animal model was designed and used by our team. The Oral mucositis index(OMI) was documented daily. Immunohistochemistry (IHC) Staining of CD34 was utilized to identify endothelial cells in the RTG tissues. Apoptosis of endothelial cells in local lesions due to RTG was detected by the TUNEL assay. The dynamic relationship between the OMI and apoptotic endothelial cells was statistically analyzed by time. RESULTS AND CONCLUSIONS: The injury and apoptosis of endothelial cells were observed 3 day post-irradiation. The vascular lumens of the post-irradiation tongue lesions were irregular; thrombosis formation in the center of the lumens, unsmooth lumen walls and vasodilated vessels were observed. Also, endothelial cells detached from the basal membrane and were found in the lumens. The percentages (%) of apoptotic endothelial cells were 78.3 ± 0.31 (5 day); 89.3 ± 0.83 (8 day); 83.5 ± 0.41 (14 day); 69.3 ± 0.57 (21 day); and 47.3 ± 0.59 (28 day). The OMI was correlated with the percentage of apoptotic endothelial cells (R=0.67, P=0.034). Summary, endothelial cell injury was correlated with the pathogenic condition of RTG.

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 mucosa involvement in rheumatoid arthritis, systemic lupus erythematosus and systemic sclerosis.

OBJECTIVES: To estimate the frequency and character of oral mucosal lesions in patients with rheumatoid arthritis, systemic lupus erythematosus and systemic sclerosis. Furthermore, the relation between oral mucosal involvement and hyposalivation was investigated. DESIGN: Case-control study. SETTING: Rheumatology Clinic, University Hospital "Mother Theresa" in Tirana, Albania. PARTICIPANTS: 124 consecutive hospitalised patients (88 with rheumatoid arthritis, 22 with systemic lupus erythematosus and 14 with systemic sclerosis) and 124 age- and gender- matched healthy controls. METHODS: Oral lesions were clinically examined and classified according to their morphologic aspects and localisation. Examination included also measurement of unstimulated whole salivary flow. MAIN OUTCOME MEASURES: Frequency of oral mucosal lesions and hyposalivation. RESULTS: Oral mucosal lesions were observed in 58.9% of patients, but in only 33.1% of control subjects. Clinical aspects of lesions varied, and palate, buccal and labial mucosa, and tongue were the most affected sites. No significant associations were found between presence of oral lesions and hyposalivation, except oral candidosis which was associated with hyposalivation in controls. CONCLUSIONS: Patients with rheumatoid arthritis, systemic lupus erythematosus and systemic sclerosis have a higher burden of oral mucosa disease than a healthy population. Collaboration of rheumatology and oral medicine units should allow appropriate management of these patients.
