Prevalence of Oral Potentially Malignant Disorders Among Tobacco Users in Kolkata: A Hospital-Based Study.

Introduction Tobacco consumption is a significant public health threat worldwide and a looming pandemic. World Health Organization data display that about five million people face premature death per year worldwide due to tobacco use. India is a leading nation among tobacco users in this regard. The aim of the present study was to determine the most prevalent tobacco consumption habit and the oral potentially malignant disorders (OPMDs) found in such users with an assessment of awareness and change in various habits. Material and methods A cross-sectional study over a duration of six months was carried out, in which every patient visiting the hospital OPD was assessed and evaluated for tobacco-related habits. A detailed history of the duration and frequency of the habit, the type of tobacco product consumed, and the predominant reason for its consumption among males and females were recorded and evaluated. An oral examination was performed to determine the evidence of OPMDs. Subjects under the age of 13 years and with systemic/metabolic disorders with oral manifestations were excluded from the study. Data obtained were subjected to statistical analysis using Stata Statistical Software, version 13.1 for Windows (released 2013 StataCorp LLC, College Station, TX). Results Data revealed a higher prevalence of tobacco consumption in males, with chewing tobacco followed by smoking and a mixed form of habit being predominant. Misri chewing was most common in females. Subjects in the 20-50 years age group were most commonly affected, with tobacco pouch keratosis being the most prevalent lesion followed by leukoplakia, with stress being a major causative factor for tobacco consumption. Conclusion The present study promulgated the prevalence of OPMDs in consumers of various kinds of tobacco products, which is highly valuable in the early detection of OPMDs. OPMDs remain unnoticed until advanced stages due to their asymptomatic or mildly symptomatic nature and due to a relative lack of awareness about the deleterious effects of tobacco usage despite an upsurge in tobacco cessation-related content on digital media. Thus, healthcare sector professionals can be appropriately guided to ensure efficient patient care at an early stage.

Understanding the Malignancy Potential of Cutaneous/Subcutaneous Lesions: Insight from 9,202 Day-Surgery Procedures

Abstract Objectives: Cutaneous and subcutaneous lesions often go unnoticed or disregarded, yet they can harbor malignant potential. These seemingly innocuous bumps and lumps vary in size and nature, necessitating thorough evaluation by health care professionals. In this study encompassing 9,202 day-surgery procedures, we sought to elucidate the malignancy risk associated with cutaneous/subcutaneous lesions. Materials and Methods: Conducted as a descriptive case-control investigation, our study enrolled patients undergoing excision for such lesions from 2009 to 2018. Patients were stratified into study (malignancy confirmed by histopathology) and control groups. Comprehensive data collection included demographic profiles, pathology reports, surgical details, and follow-up outcomes. Results: Analysis of 9,202 excision procedures involving 8,962 patients revealed epidermal/tricholemmal cyst as the most prevalent lesion type (34.5%), followed by lipomas (21.8%). Malignancies were identified in 1.1% of cases, predominantly affecting older individuals (mean age: 60.3 ± 16.2 years). While malignancy incidence correlated with advancing age, no significant gender disparity was observed (p < 0.001 and p = 0.353, respectively). Conclusion: Our findings underscore the imperative of vigilance toward cutaneous and subcutaneous lesions, as they may harbor malignancy. Timely assessment by health care providers is paramount to promptly identify and manage potentially malignant lesions. With malignancy detected in over 1% of cases, our study emphasizes the necessity for meticulous evaluation and appropriate intervention strategies to mitigate associated risks effectively.

Photographic scale for the characterization of actinic keratosis through reflectance confocal microscopy: a quantitative approach to cellular transformation.

Actinic keratosis (AK) is a highly prevalent pre-cancerous skin lesion that often leads to cutaneous squamous cell carcinoma. There are different stages of evolution of the disease and several features that characterize keratosis. This study aimed to develop a qualitative and quantitative visual diagnostic tool to facilitate the identification of the characteristics and severity of the main cellular attributes of AK and to show its applicability in evaluating the evolution or treatment through image analysis. Literature research on the main scientific databases and in the institute's database was carried out to gather all the different levels of cellular transformation. To validate the scale, a preliminary characterization study was carried out with 21 subjects who had clinically diagnosed AK lesions to classify the attributes in each skin layer and test the accuracy of the diagnosis of the scale. Afterward, and to show the possibility of a follow-up with a topical treatment, the subjects were divided into two treatment groups, receiving either a cream formulation containing retinoic acid, or a placebo formula. The evaluation was carried out through confocal reflectance microscopy and a digital camera with dermoscopic quality before and after 90 days of treatment. A table detailing the 18 attributes of AK, and a photographic scale containing RCM images graded by scores established for each characteristic and the frequency of spreading were developed. The results of the validation presented good repeatability, correlation with clinical evaluation, and capacity for differentiating treatments demonstrated by the significant improvement after topical treatment by the reduction of the score for 10 out of the 18 attributes. The preliminary study, evaluated by the detailed transformation scale highlights important differences in the subclinical approach that allows a deeper evaluation of the aspects of the lesion's re-incidence even after fully treated skin sites. This study brings an innovative method based on RCM, to assist in the quantification of cell transformation level, provide early diagnosis, and deliver a powerful treatment evaluation tool to provide smoother treatment, as well as prevent re-incidence in the cases.

Prevalence and Clinico-pathologic Profile of Biopsied Gingival Lesions from 2 Thai Dental Schools.

Gingiva can be afflicted by several pathological entities apart from gingivitis and periodontitis. There have been limited number of studies on gingival lesions, especially from Thailand. Aim: To analyze the prevalence and distribution of biopsied gingival lesions from Chulalongkorn and Rangsit Dental Schools, Thailand. Biopsy records of the participating institutions from 1995 to 2020 were reviewed for gingival lesions. The demographic data, site of lesions and diagnoses were collected. Data were analyzed by descriptive statistics. From a total of 16,207 biopsies, 1,589 cases (10.2%) were diagnosed in the category of gingival lesions. The mean age ± SD of the patients was 42.3 ± 18.6 years with the highest prevalence being in the fourth decade of life (17.4%). A male-to-female ratio was 0.48:1. The most common location was the posterior mandible (27.4%). Regarding the type of gingival lesions, non-neoplastic lesions (88.5%) outnumbered neoplastic lesions (11.5%). The most common lesion was pyogenic granuloma, followed by irritation fibroma and peripheral ossifying fibroma. Among the neoplastic lesions, squamous cell carcinoma was the most prevalent lesion followed by papilloma and lymphoma. Gingival lesions mostly occur in the fourth decade of life and have a predilection for female patients. The majority of the lesions are located in the posterior mandible. Non-neoplastic lesion, especially the reactive subtype, is the most prevalent group and pyogenic granuloma is the most common gingival lesion. Data from this study represent biopsied gingival lesions from Thailand which may be different from those of other countries. Key words:Gingival lesions, prevalence, demographic, clinico-pathological correlation, gingival biopsy.

Pathogenesis of Experimental Infection of Nile Tilapia (Oreochromis niloticus) with Nucleospora Braziliensis Pathology and Proteomic of Microsporidia.

The recent discovery of disease caused by Nucleospora braziliensis in Nile tilapia (Oreochromis niloticus) is important as it has highlighted the high prevalence of infection and associated mortality in cultured fish. Thus, this study conducted an experimental infection of this microsporidium to evaluate pathological alterations and conduct proteomic analysis. For pathological observation, samples of brain, eyes, gall bladder, gut, heart, kidney, liver, muscle, skin, spleen, and stomach tissue, were collected, and liquid chromatography-mass spectrometry (LC-MS/MS) was performed for proteomic analysis. The most prevalent lesions were brownish color of the liver, gill filament fusion, gut ischemia, hemorrhage of the lips and fins, hepatomegaly, spleen atrophy, splenomegaly, and stomach congestion. The most common microscopic lesions were degeneration, hemorrhage, and inflammation in the brain, gills, gut, kidney, liver, muscle, spleen, and stomach. The digested peptides were identified by LC-MS/MS and the intersection of each group showed that in the spleen there were 121 exclusive proteins in the infected sample and 252 in the control, while in the kidney, 129 proteins were identified in the infected specimen compared to 83 in the control. In conclusion, this study demonstrates the proteome profile of O. niloticus kidney and spleen tissue in response to infection with N. braziliensis.

Novel 3-dimensional classification of cervical abrasion using CBCT: A comprehensive analysis

IntroductionTooth cervical abrasion (CA) is a prevalent non-carious cervical lesion that poses challenges for accurate diagnosis from periapical radiographs due to difficulties in assessing the lesion's extent, associated bone loss, and pulpal involvement. The presence of overlying bone structures on the palatal side when lesions are located on the buccal side, or vice versa, further complicates radiographic interpretation. So it is important to define the lesions in all three dimensions. ObjectiveTo provide a three-dimensional descriptive classification for cervical abrasion lesions using Cone Beam Computed Tomography (CBCT). MethodA total of 50 patients with cervical abrasion were selected for the study. From these patients, teeth (n = 10) from each of the four different quadrants were chosen. A CBCT scan with a 6 × 6 cm field of view (FOV) was performed, and the DICOM files of the cervical lesions were transferred to 3-D imaging software. The CBCT images of the cervical abrasion lesions were assessed at the level of the deepest point of the lesion along the long axis of the tooth in both axial and sagittal planes. The height (A), buccolingual dimension (B), circumferential spread (C), and remaining dentine thickness (D) were evaluated and classified using new scoring criteria for each dimension. The reliability and reproducibility of the classification were assessed to ensure its clinical applicability. ConclusionCBCT can be utilized to classify tooth cervical abrasion in endodontics, enhancing diagnosis, analysis, and treatment outcomes. This three-dimensional view facilitates easier communication among clinicians, allows for tailored treatment approaches, and opens new avenues for research.

A molybdenum sulfide based nitric oxide controlled release oral gel for rapid healing of oral mucosal ulcers

Oral mucosal ulcer is the most prevalent oral mucosal lesion, affecting over 25 % of general population. The current treatment regimens lack efficacy in addressing challenges such as wound bleeding, bacterial infection and inflammation on a continuous basis. Hence, a multi-functional oral gel (termed MPCST) with a long-acting duration is designed. It is based on a tannic acid-thioctic acid (TATA) supramolecular hydrogel which absorbs tissue exudate while exhibiting robust tissue adhesion properties. To form MPCST, TATA is loaded with MPCS, which are composed of polydopamine (PDA)-coated molybdenum disulfide (MoS2) nanoflakes (MoS2@PDA) with high photothermal conversion efficiency, nitric oxide (NO) precursor nitroprusside (SNP) and cerium oxide (CeO2) with high reactive oxygen species (ROS) scavenging rate. Upon exposure to 808 nm near-infrared (NIR) irradiation, MPCS rapidly heats up and releases NO to promote angiogenesis, while exhibiting strong ROS scavenging, antibacterial (including oral common Streptococcus mutans), and anti-inflammatory properties. Animal experiments show that the MPCST oral gel, composed of MPCS and TATA hydrogel, exhibits superior therapeutic efficacy compared to the commonly used dexamethasone patch.

Florid vascular proliferation due to focal necrotizing enterocolitis in infancy: A case report

Vascular anomalies rarely emerge in the gastrointestinal tract. The most prevalent benign vascular lesions include angiodysplasia, Dieulafoy’s lesion, vascular ectasia, vascular malformations, and hemangiomas. Florid vascular proliferation (FVP) is also a rare benign vascular lesion associated with intussusception in adults. In infants, there are only a few cases in literature. Although FVP usually presents as a mass in the intestine, it is a nonneoplastic lesion and is thought to occur due to a reactive process. In this study, we present a case of FVP due to an attack of focal necrotizing enterocolitis in a 10-month-old infant.

Which Is More Harmful for the Oral Mucosa: Cigarettes or Hookah? A Cross-Sectional Study

Background: The popularity of hookah usage is on the rise in contemporary societies. Some individuals believe that using a hookah is less harmful than smoking traditional cigarettes. Objectives: The objective of this study was to examine the prevalence of oral mucosal lesions among individuals who use hookah and cigarettes. Methods: In a cross-sectional study conducted at Ahvaz Dental School, 102 individuals seeking examination and treatment for dental problems were recruited from spring 2022 to winter 2023 and categorized into three groups: Cigarette users (A), hookah users (B), and non-users of both (C). A thorough oral examination was performed on each patient to identify any oral mucosal lesions. If necessary, a biopsy was performed to confirm the diagnosis. The information for each patient was recorded on individual sheets and subsequently analyzed. To examine the relationship between qualitative variables, a chi-square test or Fisher's exact test was employed. Results: The most prevalent oral mucosal lesion observed in both group A (42%) and group B (27%) was hyperpigmentation of the oral mucosa. Notably, a premalignant lesion was exclusively observed in individuals belonging to group A (7%). Complaints of bad taste in the mouth were more common in tobacco users (in any form) than in non-users (P = 0.004). Conclusions: Tobacco users (of any kind) have more oral lesions than non-smokers, although most of these lesions are harmless.

Alternative Venous Pathways: A Potential Key Imaging Feature for Early Diagnosis of Sturge-Weber Syndrome Type 1.

Sturge-Weber syndrome is a rare congenital disorder characterized by cortical atrophy and calcifications on late-stage imaging. Understanding the evolution of brain lesions is crucial for effective early interventions, yet the timeline remains unclear. We aimed to evaluate early brain MRI findings and their progression longitudinally on follow up MRI in children diagnosed with Sturge-Weber syndrome. We retrospectively included all children with a confirmed diagnosis of Sturge-Weber syndrome between 2009 and 2023 that had at least 2 available MRIs performed before the age of 2 years. A pediatric radiologist and a pediatric neuroradiologist evaluated all the MRI scans for pial enhancement, choroid plexus enlargement, atrophy, calcifications, a prominent subarachnoid varicose network, trans medullary veins, subependymal veins, and deep extra ventricular veins. Descriptive analysis was used for demographic data and brain lesion prevalence. Cumulative incidence curves were used to show the timeline of emerging lesions. K-means clustering was used to categorize the lesions based on their prevalence at 1, 2, 3, 6, 12, 18, and 24 months after birth. Nine patients met the inclusion criteria. Median ages at the first and last MRIs were 35 days (IQR: 11-123) and 294 days (IQR: 208-465), respectively. The most prevalent lesions at the first MRI were subarachnoid varicose network (88.9%) and trans medullary veins (77.8%), while prevalence of atrophy and calcifications differed most between the first and last MRIs. The results of the elbow method and K-means clustering showed that we can divide Sturge-Weber syndrome lesions into 3 groups based on their timeline of emergence. The first cluster contained subarachnoid varicose network, trans medullary veins, subependymal veins, and choroid plexus enlargement. The second cluster contained deep extra ventricular veins, pial enhancement, accelerated myelination, and atrophy. The last cluster contained calcifications. Our findings suggest that dilated venous channels emerge early as a compensatory mechanism, preceding atrophy and calcification. Additionally, these dilated channels precede the appearance of abnormal contrast enhancement of the pia, often termed leptomeningeal angioma. This underscores the importance of early recognition and monitoring of these initial imaging indicators in clinical practice.

Advancements and challenges in understanding gastrointestinal stromal tumors: A comprehensive review

The most common mesenchymal tumor affecting the gastrointestinal system is gastrointestinal stromal tumor (GIST). Although GISTs are a relatively new type of tumor, the under understanding of these tumors has increased quickly. Nevertheless, there is a dearth of research on this illness in India, and the majority of treatment plans are based on studies performed on populations outside of the nation. Since the 1990s, considerable progress has been made in our knowledge of the lineage of origin of the GIST domain. According to recent research, multipotent mesenchymal stem cells are the source of GISTs, which are thought to occur in 10-20 cases per million people annually. With the overexpression of the tyrosine kinase receptor KIT in intestinal Cajal cells, GISTs are the most prevalent malignant subepithelial lesions (SELs) in the digestive tract. GISTs can have a variety of morphologies, such as rhabdomyosarcoma, angiosarcoma, or undifferentiated pleomorphic sarcoma, which makes diagnosis difficult. However, new developments in molecular targeted therapy have transformed solid tumor oncology and provided exciting new avenues for treatment. To differentiate dedifferentiated GISTs from other gastrointestinal malignancies, this review paper will address current immunohistochemical markers and provide an outline of the morphologic and molecular features of these tumors. The findings also emphasize the importance of GIST genetic testing, progressive surgical approaches, adjuvant and neoadjuvant therapy for localized disorders, and metastatic condition-addressing methodologies. This article's major body explores the impact of imatinib therapy, the rarity of GISTs in pediatric patients, imaging methods for staging and monitoring, and difficulties with treating anorectal GISTs. This study highlights how crucial it is to pinpoint particular molecular subtypes to inform therapeutic choices for adjuvant and metastatic therapies.

Giant Epidermoid Cyst of the Scalp Growing for 76 Years

Epidermoid cysts are prevalent noncancerous cutaneous lesions known to exhibit unusually extended periods of growth. In this study, we present a remarkable case of an epidermoid cyst located on the scalp, which exhibited a growth period of 76years, the longest growth time documented in the literature to date. The presence of the mass was noted at birth, and it exhibited gradual growth throughout the years, with a notable acceleration observed during the final 2 years. The patient underwent a surgical excision, and the histopathological analysis was consistent with epidermoid cyst, featuring localized rupture and demonstrating foreign body granulomatous inflammation. This case highlights the ability of epidermoid cysts to manifest as slow-growing entities over an exceptionally prolonged timeframe. Furthermore, instances of rapid growth may be attributed to a combination of mass rupture and inflammatory processes.

Pink and Blue of Bones- A Histopathological Analysis of Bony Neoplasm in a Tertiary Hospital of Bihar

Background: Bone lesions have low incidence with diverse presentation and due to the presence of their limited studies it has become a challenging task to reach an accurate diagnosis. Aim and Objective: This study aims in studying variety of bony lesions observed clinically and histopathologically. Further categorizing into non neoplastic, tumour-like, benign tumour or malignant tumour and determining its correlation with the age and gender predisposition of these lesions. Materials and Methods: An ambispective study was executed in Pathology department , PMCH, Patna from May 2020 to April 2024 in which a total of 102 cases were collected. The necessary information for the retrospective analysis, such as the patient's age, sex, lesion location, and diagnosis, was obtained from the requisition form and the histopathology data kept in the department of pathology from May 2020 to May 2022. And for prospective study all the radiological proven bony lesions which were excised during period of May 2022 to April 2024 and were sent for histopathological examination were examined. Results: Non-neoplastic lesions were more common than neoplastic lesions among the 102 specimens that underwent histological examination (53 versus 49). With 21.5% of cases, tuberculous osteomyelitis was the most prevalent non-neoplastic lesion. The most common benign neoplastic lesion detected was a giant cell tumor of the bone (11.76%), while the most common malignant lesion found was osteosarcoma (2.94%). Conclusion: To improve patient management and diagnosis accuracy, it is advised to utilize clinical, radiological, and histological findings in an integrated manner.

Oral mucocele: A narrative review

A mucocele stands out as the most prevalent mucosal lesion found in the oral cavity. It is characterized as a cyst filled with mucus that can manifest within the oral region. This condition arises from the buildup of mucus secretion triggered by the factors such as trauma, habits like lip-biting, or changes in minor salivary gland function. Oral mucoceles (OMs) represent benign masses of soft tissue, typically appearing as smooth, spherical, translucent nodules with a soft consistency, commonly observed in the buccal mucosa or lips. OM can manifest anywhere within the oral mucosa, including the lips, cheeks, and floor of the oral cavity, although it predominantly occurs in the lip region. There are two primary types of OMs such as extravasation and retention types. OM mostly affects young patients but can affect all groups. OMs typically present as asymptomatic, although occasionally they may cause discomfort by hindering chewing, speech, or swallowing. The diagnosis of OM is based on the clinical appearance and history. The histopathological study confirms the diagnosis of OM. Treatment options for OM encompass various approaches such as complete excision, marsupialization, cryosurgery, carbon dioxide laser therapy, electrocautery, and intralesional injection of sclerosing agents. This review focuses on details of OM including its etiopathology, classification, clinical features, and its current management.

Preparation of iron nanoparticles mediated by Punica granatum and its application for the treatment of denture stomatitis

Denture stomatitis affects around 50% of denture wearers in certain populations as a prevalent oral mucosal lesion. There has been a high interest in utilizing natural antibacterial composites, such as medicinal plants extracts. Punica granatum, a popular medicinal plant, has various pharmacological applications. In this particular research, iron NPs were formulated by the Punica granatum aqueous extract, following the principles of green chemistry. The study objective was to assess the effectiveness of FeNPs on denture stomatitis. The usual analytical examinations were applied for FeNPs. The FE-SEM results confirmed that the nanoparticles exhibited a spherical morphology, with sizes ranging from 21.6 to 65.8 nm. This clinical trial involved 30 patients who received FeNPs. Over a period of two weeks, the patients were instructed to consume the mouthwash four times per day, with 15–20 drops each time, for a duration of 2–3 minutes. Following the mouthwash, they were advised to refrain from eating or drinking for 0.5 hour. The patients in both classes were instructed to consume the medication at particular times. The erythema and inflammation levels were recorded and assessed at each session using a 6-point scale and a graded blade. Additionally, palatal mucosa mycological samples were collected for culture during each visit. The data revealed a notable reduction in the palatal erythema surface compared to the initial condition in the follow-up visits. This study suggests that FeNPs can effectively reduce the Candida colonies number and the area affected by erythema in the denture stomatitis management.

Animal diseases in the southern part of the Carpathian Basin during the medieval period

AbstractThis study aims to shed light on animal management influences on the development of pathological changes observed on animal remains from the medieval site of Crkveno Brdo. Animal remains with abnormalities were discovered during archaeological excavations of the medieval settlement at the site of Crkveno Brdo in 2019. The site is situated near Senta in the northern region of modern‐day Serbia. The part of the settlement dated from the 11th to the 15th centuries was excavated. The percentage represented by various mammalian species documents that the most important economic species were cattle and horses, followed by sheep, goats, and pigs. Fishing and hunting were marginal in the settlement subsistence. The analyzed assemblage of bones with lesions consists of 39 specimens with 40 abnormalities. All of the remains exhibiting abnormalities were subjected to macroscopic and stereomicroscope analysis. The specimens with the most prominent changes also underwent x‐ray imaging and histopathological analysis. Almost all lesions were found in domestic animals. The most prevalent lesions in cattle, sheep, goat, and pig were dental and oral pathology, followed by articular abnormalities. In horses, 77% of pathological changes were articular abnormalities, and 11% dental and oral pathology, followed by traumatic lesions and inherited disorders (5.5% each). Congenital morphological variation is represented by a single specimen of horse lumbar vertebra. Pathological alterations were also noted in dogs, as was a severe healed tibiofibular fracture in a frog. Pathological alterations were related to external factors and specifically to patterns of animal management. Dental pathologies in cattle, sheep/goats, and pigs were primary attributed to malnutrition quality; articular abnormalities in horses, similar to aging and environmental factors, most likely work related.

Oral Lesions of Immune-Mediated and Autoimmune Diseases: A 12-year Experience at a Single Brazilian Referral Center.

Oral lesions of immune-mediated and autoimmune diseases have been well-documented, but studies from Brazil are limited. The varied spectrum of oral lesions within this demographic group poses challenges to clinicians, particularly when they occur in isolation. This study aimed to evaluate the occurrence, clinical characteristics, and management of patients with oral lesions of immune-mediated and autoimmune diseases at a single center in Brazil. A retrospective cross-sectional study was conducted from 2010 to 2022. Clinicodemographic data, histopathological features, and treatment modalities were analyzed descriptively and analytically. Of the 3,790 oral and maxillofacial lesions diagnosed, 160 (4.2%) were confirmed as immune-mediated or autoimmune diseases. The population surveyed predominantly consisted of women (73.7%), with a mean age of 60.2years. Oral lichen planus (51.3%), mucous membrane pemphigoid (MMP) (23.7%), and pemphigus vulgaris (PV) (19.4%) were the most prevalent lesions. The buccal mucosa (59.4%) was predominantly affected, with pain reported in 46.2% of cases, notably in individuals with PV and MMP. The average time to disease stabilization post-local and/or systemic corticosteroid therapy was 15.8months for systemic lupus erythematosus, 8.7months for MMP, and 6.5months for PV. Although oral lesions related to immune-mediated and autoimmune diseases are uncommon, their diverse clinicopathological aspects require multidisciplinary management.

Frequency of Oral Lesions, Olfactory, and Gustatory Disorders and Xerostomia in Patients with COVID-19.

COVID-19, a respiratory illness with a global impact on millions, has recently been linked to manifestations affecting various bodily systems, including the oral cavity. Studies highlight oral issues, like ulcers, blisters, and white patches, alongside olfactory and gustatory dysfunction, influencing an individual's quality of life. In this context, our study aimed to assess the frequency of oral lesions, olfactory and gustatory disorders, and xerostomia resulting from COVID-19. An observational study was conducted with 414 patients to evaluate the frequency of oral symptoms resulting from COVID-19. Patients were diagnosed with mild symptoms and evaluated through clinical examination of the oral cavity and a questionnaire to assess functional alterations. The findings showed that 139 out of 414 patients presented clinical manifestations, with oral lesions being the most prevalent (19.1%), followed by gustatory disorders (18.1%), xerostomia (14.2%), and olfactory dysfunction (14%). The most prevalent oral lesions were ulcerations (n = 51), candidiasis (n = 8), and erythema or red plaques (n = 7). Unfortunately, 50 (12.1%) patients died during this study. Therefore, oral lesions, olfactory and gustatory dysfunctions, and xerostomia are common symptoms associated with COVID-19.

Prevalence of Premalignant Conditions and Their Transformation Into Oral Cancers: A Clinical Study.

The purpose of this study is to look at how often premalignant oral diseases are among patients who visit a tertiary care center, as well as how often these problems progress to become mouth malignancies. Between 2017 and 2022, 200 patients at a tertiary care facility who were identified with premalignant oral lesions had their medical records retrospectively examined. Information on lesion features, histological results, and demographics was gathered. Statistical analysis was used to determine the prevalence of premalignant oral lesions and the rate at which these lesions turned into oral malignancies, with a significance threshold of P < 0.05. The research population's mean age was 55 years (SD ± 10), with a 65% male preponderance. The most prevalent premalignant lesions were leukoplakia (45%), erythroplakia (30%), and oral submucous fibrosis (25%). Remarkably, during follow-up, 40% of patients showed development of premalignant lesions into mouth malignancies. Based on statistical analysis, there were significant correlations (P < 0.05) between dysplastic alterations, age, tobacco use, and the development of oral malignancies from premalignant lesions. In conclusion, this study highlights the need of early diagnosis and focused therapies in tertiary care settings by offering important insights into the occurrence and evolution of premalignant oral lesions. The results provide important information that may be used to create screening programs and preventive measures that will lessen the incidence of oral cancer.
