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

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

Non-Communicable Diseases and Associated Risk Factors in Burning Mouth Syndrome Patients.

Background and Objectives: Noncommunicable diseases (NCDs) are a group of non-transmissible conditions that tend to be of long duration and are the result of a combination of genetic, physiological, environmental, and behavioral factors. Although an association between oral disorders and NCDs has been suggested, the relationship between Burning Mouth Syndrome (BMS) and NCDs and their associated risk factors has not been deeply investigated. In this study, we aim to identify associations between BMS and NCDs in the Romanian population. Materials and Methods: Ninety-nine BMS patients and 88 age-matched controls (aged 50 and over) were clinically evaluated for the presence of eight noncommunicable diseases (NCDs) and their most common risk factors, including hypertension, dyslipidemia, smoking, and obesity. Results: The results of our study showed that the BMS in the Romanian population seems to be significantly associated with cardiovascular diseases (CVDs) (p < 0.001) and two of their risk factors, hypertension (p < 0.001) and dyslipidemia (p < 0.001). Moreover, evaluating the Framingham Risk Score (FRS) in the individuals not affected by CVDs (73 CTRL and 38 BMS), we found that 13.2% of BMS patients reported a moderate risk of developing CVDs in ten years, compared to the controls, all of whom presented a low risk (p = 0.002). Conclusions: Our findings suggest that a multidisciplinary clinical approach, which also includes a cardiovascular evaluation, is essential for the successful management of BMS. Moreover, these data highlighted the importance of introducing an integrated strategy for the prevention and care of NCDs in BMS patients.

Impact of Altered Lipid Profile in Oral Lichen Planus.

Background:Oral lichen planus (OLP) is a chronic inflammatory disease that affects the oral mucosa. This disorder has been suggested to be related to an impairment of lipid metabolism and profile. A number of studies indicate a higher incidence of dyslipidemia in OLP patients compared to not-affected individuals. Objectives: The aim of this study was to investigate the correlations between lipid profile alterations and clinical features of oral lichen planus. Patients and methods:A total of 52 patients diagnosed with OLP were enrolled in this study. Data regarding the demography, symptoms, severity of lesions assesed by Thongprasom score and lipid profile status were collected from the medical charts. The study group was divided into two sub-cohorts: Group 1, which included OLP patients with lipid profile within the normal range, and Group 2 comprising OLP patients with alterations of the lipid status. Results:The comparative analysis between the two groups found a statistically significant association between the lipid profile and OLP symptoms. Thus, the most frequent symptom was pain, in OLP patients with normal lipid status (Group 1), and burning, in those with altered lipid status (Group 2) (p=0.050). Moreover, the presence of symptoms was reported by a higher percentage of patients from Group 2 (75%) than Group 1 (68.25%). Patients reporting burning symptomatology showed higher triglyceride levels than those who reported pain (p=0.032). Furthermore, we found that male OLP patients have higher levels of LDL compared with female subjects (p=0.021). Conclusion:Lipid profile changes are not associated with an increased severity of OLP lesions. A statistically significant association was found between burning sensation and higher lipid profile parameters.

Oral leukoplakia: A clinicopathological study and malignant transformation.

OBJECTIVES: To assess the clinicopathological characteristics of a cohort of patients with oral leukoplakia (OL) managed in a Romanian dental hospital and to evaluate the risk of malignant transformation (MT). MATERIALS AND METHODS: We conducted a hospital-based retrospective study using the clinical charts of patients diagnosed with OL that had complete clinical and histopathological evaluation followed up for 1-16 years. RESULTS: From 120 included patients, 68 (56.7%) were females, and 71 (59.2%) were current smokers. The homogeneous form was present in 60% of cases; the buccal mucosa was the most frequently involved site. MT was observed in 9 cases, which was more common in females and in those with dysplastic leukoplakia. A significant statistical association was found between MT and dysplasia grade (χ2 test: p = 0.007). MT occurred during a mean interval of time 75 months in both treated and non-treated patients. CONCLUSIONS: In this leukoplakia cohort, most of the lesions encountered were in smokers, clinically homogeneous and 62.5% proved histologically benign. But despite the clinically benign appearance of leukoplakia, tissue diagnosis of some cases was carcinoma. The results of the current study advocate the necessity for biopsy even in apparently homogeneous, clinically benign lesions. The malignization rate was 7.5%; two-thirds were nonhomogeneous lesions.

Oral Leukoplakia. A Five-Year Follow-Up Study.

Background: Oral leukoplakia (OLK) is the most studied oral potentially malignant disorders in the scientific literature. Its malignant transformation (MT) rate varies between 1.1% and 40.8%, depending on the type of study and population group studied. There is no universal agreement to treat or manage these lesions, so it is up to each clinician's experience and expertise in how he/she manages these patients. Objective:The aim of this retrospective study was to assess the clinical aspects and pattern of evolution of OLK in 30 patients five years or more after the initial diagnosis. Material and methods:We selected 30 OLK patients from our database. Demographic, clinical and evolutive data was retrieved from the medical files. The following variables were analysed: age and sex, smoking habits, clinical features (form, dimension, site of the lesion), result of mycological examination, treatment and outcomes of the lesions over a follow-up of more than five years. Results:For a follow-up of 119.63 months, we detected a value of 0.2% MT rate per year. Outcomes varied from the complete disappearance of the lesion to recurrence and malignant transformation with a variety of treatment methods applied. Conclusion:Despite the low MT rate for a long follow-up, it is hard to say which treatment method is the best, due to the heterogeneity of the clinical aspects of the lesions and because there is no standardised test method, either genetic testing or immunohistochemical testing. We recommend a varied approach, suitable for each patient's needs and medical context, always when possible histopathological confirmation for grading epithelial dysplasia, which remains the most reliable method of checking the process of malignant transformation.

The Implication of Candida Infection in Oral Lichen Planus Lesions.

Objectives: The purpose of this study is to determine if superimposed infection with Candida species in oral lichen planus exacerbates the clinical symptoms and lesions. Methodology:We conducted a retrospective study on the medical charts of oral lichen planus (OLP) patients diagnosed by clinical and histopathological criteria. A baseline demographic, anamnestic, clinical data, results of the oral candida investigations were analyzed and recorded for all patients. Results:From a total number of 203 OLP patients, oral candidiasis was diagnosed in 75 (36.94%) cases. There was no statistical significance between the clinical forms of lichen planus and the presence of Candida infection. Of all encountered Candida species, Candida albicans was most commonly detected, followed by Candida krusei, Candida lusitaniae, and Candida tropicalis. Conclusion:Although our study is limited regarding the sample size and no statistically significant difference has been found between clinical features of OLP and oral candidiasis, a routine screening of OLP patients for oral candidiasis and a preventive antifungal strategy in the OLP treatment schedule is needed.

High-risk human papillomavirus in patients with oral leukoplakia and oral squamous cell carcinoma-A multi-centre study in Sweden, Brazil and Romania.

OBJECTIVES: Although causal associations between oral leukoplakia (OL), oral squamous cell carcinoma (OSCC) and high-risk human papillomavirus (HR-HPV) have been speculated upon in several reports, conclusive evidence has not been presented. This study investigates whether the number of cases of HR-HPV in OL has increased over time and whether the prevalence of HR-HPV-positive OL differs in various parts of the world. PATIENTS AND METHODS: A total of 432 patients with OL from Sweden, Brazil and Romania were analysed. Patients were divided into historical (1992-2002) and contemporary (2011-2017) cohorts from the respective countries. Seventeen patients with OL developed oral squamous cell carcinoma (OSCC). A real-time PCR assay, targeting HPV sub-types 6,11,16,18,31,33,35,39,45,52,56,58 and 59, was performed to detect HR-HPV in patients with OL. RESULTS: In the Swedish and Romanian cohorts, none of the investigated HPV sub-types were detected. In the Brazilian cohorts, five patients with OL (3%) were positive for HR-HPV, including four patients from the contemporary cohort (HPV 16, 31, 33) and one from the historical cohort (HPV 11). All the cases of OL that transformed into OSCC were HR-HPV-negative, as were the corresponding tumours. CONCLUSIONS: In summary, the prevalence of HR-HPV in OL is low in all the tested countries, and the incidence has not changed over time. HR-HPV in OL does not seem to be a driver of oncogenesis.

Oral medicine (stomatology) across the globe: birth, growth, and future.

Oral medicine (stomatology) is a recognized and increasingly important dental specialty in many parts of the world that recognizes and fosters the interplay between medical health and oral health. Its dental activities rely greatly on the underlying biology of disease and evidence-based outcomes. However, full recognition of the importance of oral medicine to patient care, research, and education is not yet totally universally acknowledged. To address these shortcomings, we outline the birth, growth, and future of oral medicine globally, and record identifiable past contributions to the development of the specialty, providing an accurate, unique, and valuable resource on oral medicine. Although it was challenging to gather the data, we present this information as a review that endeavors to summarize the salient points about oral medicine, based on MEDLINE, other internet searches, communication with oral medicine and stomatological societies across the world, the web page http://en.wikipedia.org/wiki/List_of_dental_organizations, and discussions with a wide range of key senior persons in the specialty.

Oral erythema multiforme: trends and clinical findings of a large retrospective European case series.

OBJECTIVE: Erythema multiforme (EM) continues to be an underestimated disease with a lack of strict classification and diagnostic criteria. We present the analysis of a case series of 60 oral EM patients from 2 centers and illustrate the range of oral clinical presentations. STUDY DESIGN: Clinical data from 60 EM patients with oral involvement, diagnosed and treated between 1982 and 2014, were retrospectively collected from the archives of 2 independent hospitals. Statistical analyses of the data were performed using the Pearson χ-squared test and the Mann-Whitney U test. RESULT: Thirty-one patients (51.7%) were male and 29 (48.3%) were female, with a mean (±SD) age of 37.9 years (±18.1). The frequency of previous occurrences ranged from 0 to 10 (mean ± SD: 1.4 ± 2.0). Twenty-nine patients (48%) had no previous occurrence. Medications (particularly antipyretics, food additives, and antibiotics) were the suspected precipitants in 28 patients (46.7%), whereas herpes simplex virus infection was suspected in 18 (30.0%). All but 1 patient had involvement of multiple oral sites, with the buccal mucosa being the most commonly involved oral site (75%), followed by the vermillion border (71.7%). CONCLUSIONS: Patients with EM may present initially to oral health care workers. Medications and herpes simplex virus continue to be the most typically involved precipitating factors. Our data highlight the additional role of food-derived antigens. Although laboratory tests can provide support diagnostically, EM diagnosis continues to be based on clinical features. A medication and food diary should be encouraged particularly in patients with recurrent forms.

Oral leukoplakia - an update.

ABSTRACT: The main purpose of this paper was to assess the current state of science on oral leukoplakia. Although it is considered a potentially malignant disorder the overall malignant progression of oral leukoplakia is of the order of 5% and even more. Nowadays there are no currently accepted markers to distinguish those that may progress to cancer from those that may not. The current golden standard is considered the presence of epithelial dysplasia on the tissue biopsy of the lesion. Proliferative verrucous leukoplakia is a rare form of OL which has multiple recurrences, is refractory to treatment and has malignant transformation in a short period. It is considered a true premalignant lesion. The management of oral leukoplakia varies from a "wait and see" attitude and topical chemopreventive agents to complete surgical removal.

Association of oral lichen planus with chronic C hepatitis. Review of the data in literature.

ABSTRACT: The relationship between chronic hepatitis C virus infection (HCV) and oral lichen planus (OLP) is a current topic in the field of oral medicine. Many studies of this association have been made over time. The geographic variation of the hepatitis C prevalence proved to be an important factor influencing the statistical results of the studies analyzing the association of the oral plan lichen with the hepatitis C virus. Approaching this issue is not to be neglected. Treatment outcomes in patients with oral lichen planus associated with chronic hepatitis C virus are often unsatisfactory compared to patients suffering from idiopathic oral lichen planus. Also, the evolution of oral lesions is often fluctuating, with repeated periods of relapse according to the degree of liver function decompensation. Background therapy for liver disease itself may influence lichen planus lesions. Thus, during therapy with interferon and ribavirin oral lesions may appear or become acute.

Oral lichen planus: A retrospective study of 633 patients from Bucharest, Romania

Objective: In this retrospective study, patients’ medical records were reviewed to investigate the profiles of 633 OLP cases in a group of Romania. Material and Methods: In this retrospective study, the following clinical data were obtained from the medical charts of patients: gender, age, clinical presentation of OLP, site affected, presence of symptoms, extraoral manifestations of lichen planus, presence of systemic diseases, and history of medications. Results: Most (78.67%) OLP patients were female and the mean age at presentation was 52 years. The white type of the disease (reticular/papular/plaque lesions) was the main form encountered in this sample (48.97%). Among patients with available hepatitis C virus test results, 9.6% were serum-positive. OLP was associated with gallbladder disease (i.e. cholecystitis, cholelithiasis) in 19% of patients. Six patients (0.95%) developed squamous cell carcinoma at a site with confirmed OLP lesions. Conclusions: To the best of our knowledge, no similar study has been conducted in a Romanian population. The present investigation revealed the predominance of OLP among middle-aged white women and the prevalence of bilateral involvement of the buccal mucosa with reticular white lesions. Anti-HCV circulating antibodies were more common in patients with OLP than in the general population and, notably, OLP was associated with gallbladder disease (cholecystitis, cholelithiasis) in 19% of patients (AU)

Oral complications associated with D-penicillamine treatment for Wilson disease: a clinicopathologic report.

BACKGROUND: Wilson disease (WD) is a hereditary disease inhibiting copper release from the liver. Multi-organ manifestations involve the liver, nervous system, kidneys, eyes, heart, and skin. Elastic fiber damage is a complication of the most frequently used medication in the treatment of WD D-penicillamine (D-PCA). These changes have very rarely been described in the oral cavity. The article describes oral complications associated with WD and its treatment by D-PCA. METHODS: Clinical, radiographic, and microscopic evaluation was done on two WD female patients (aged 28 and 53), treated by D-PCA, with clinical and pathological evidence for oral drug-related complications. RESULTS: The lesions included multiple small red papules of the lips, gingival enlargement, early onset periodontitis, and repeated oral candidiasis. Biopsies of oral mucosa (gingiva, buccal) exhibited in one case granulomatous inflammation, and in both cases, thick irregular clumps of tortuous, red-staining abnormal elastic fibers. The red lip papules resemble elastosis perforans serpiginosa (EPS). Similar lesions have been described in the skin, but never before in association with oral or perioral tissue. In addition to the oral lesions, one of the patients developed general intolerance to the drug and was switched to trientine hydrochloride. CONCLUSIONS: WD patients and others treated by D-PCA may develop oral and perioral complications, in some cases exhibiting features of damaged elastic fibers in the mucosa and periodontal apparatus. It is possible that this damage may be one of the factors responsible for poor periodontal health in WD patients. Recognition of the lesions can lead to replacement of the affecting therapeutic agent.

Primary herpetic gingivostomatitis in children and adults.

OBJECTIVES: To investigate if the onset of primary herpetic gingivostomatitis (PHG) is shifting toward an adult age and compare the clinical characteristics of PHG between children and adults. METHOD AND MATERIALS: The charts of patients diagnosed with PHG in an oral medicine clinic in Bucharest, Romania, over a 10-year period were revisited. Diagnosis was based on history, clinical data, and laboratory confirmation (Tzanck cytology, polymerase chain reaction [PCR], or immunofluorescence). Seventy-three cases (38 females, 35 males) were included. The age range was between 22 months and 53 years, with a mean age of 18.6 years. All patients were healthy with no suspicion of HIV infection or immunodeficiency. RESULTS: Nearly 48% (47.94%) of the sample were in the young adult group. General symptoms (fever, malaise, and lymphadenopathy) were equally present in children and adults. The most involved areas were the gingiva, vermilion border, and tongue. No differences in the extent of lesions were observed between children and adults. Inflammatory gingivitis and pharyngotonsillitis were more frequent in children than in adults although their frequency was less than expected. CONCLUSIONS: PHG was more frequently observed in young adults than in children. No significant differences between children and adults in the severity of infection were observed. Most of the patients presented widespread lesions.

Primary oral tuberculosis: a case series from Bucharest, Romania.

Tuberculosis (TB) is a chronic granulomatous disease that affects various systems of the body. Although the pulmonary form is most common, TB can also occur in the lymph nodes, kidneys, bones, and oral cavity. Oral TB is often a consequence of active pulmonary TB and is relatively rare. Here, we report a series of cases that emphasize the importance of considering oral TB in the differential diagnosis of mucosal lesions. In addition, although primary oral TB was previously considered a disease of the young, these cases demonstrate that it may occur in subjects of all ages.
