Oral submucous fibrosis in a 11-year-old Bangladeshi girl living in the United Kingdom

Efficacy of spirulina in management of oral submucous fibrosis − a systematic review

Objective: The aim of this systematic review was to evaluate the efficacy of spirulina in the management of oral submucous fibrosis. Methodology: Databases (MEDLINE via PubMed, Cochrane, EBSCO-host, Scopus, Science Direct, Clinical Trial Registry- India (CTRI) and Google scholar), review articles, bibliographies and related journal were searched from 1st January 2010 to 30th May 2020, using various combinations of MeSH terms and keywords. Results: A total of 5 clinical trials were analysed for the review, of which 4 were randomized controlled trials and 1 was non-randomized controlled trial. Mouth opening and burning sensation were analysed as primary outcome in all 5 studies. For both outcomes some studies reported statistically significant difference whereas others showed non-significant results on comparing with different interventions. Also, high risk of bias was observed among studies after performing quality analysis. Conclusion: Although the studies suggest efficacy of spirulina in management of OSF, but due to the high risk of bias there is a weak evidence regarding the effectiveness of spirulina in treating OSF. So, more uniform and standard trials on larger population should be carried out.

No age predilection for a disease like OSMF. A case report of 5-year-old child

Background

Oral Sub Mucous Fibrosis (OSMF) is a clinical entity, well known since the time of Sushruta as 'Vidari'. OSMF is a chronic subtle disease that is associated with significant functional morbidity and an increased risk for malignancy. Generally, OSMF is considered as an adult disease, but recently Indian suburb area has reported incidence of 0.2-1.2 percent in pediatric age group as well. The pathogenesis of the disease is not well established, but is believed to be multifactorial. Areca nut chewing is considered as the major etiology amongst all. Children indulge in habit of chewing areca nuts due to its easy availability of different forms of multicolored attractive areca nut pouches in markets. Other factors involved in the consumption of Areca nut are levels of awareness, household environment, peer pressure, low cost, etc.

Case presentation

A 5-year-old boy reported with the complaint of restricted mouth opening since 3-4 months. He had habit of chewing betel nut, a minimum of 2-3 sachets daily since one and a half years. He also complained of intolerance to spicy food. The oral mucosa was pale, opaque, blanched with a reduced mouth opening of interincisal width being 06 mm.Palate was fibrotic with shrunken uvula.

Conclusion

This Case of OSMF in a 5-year-old boy is reported to be the first incidence of OSMF in a child with least interincisal opening of 06 mm.

Oral Submucous Fibrosis in Pediatric Patients: A Systematic Review and Protocol for Management

AIM

To conduct a systematic review evaluating the cases of oral submucous fibrosis in pediatric patients.

MATERIAL AND METHOD

Systematic review was conducted using PRISMA guidelines. The article focused on oral submucous fibrosis in pediatric patients were included. A total of five manuscripts were included in our systematic review. The prevalence of OSMF in pediatric patients, gender distribution, causes, and clinical presentation were reviewed.

RESULTS

On systematically reviewing, a total of 10 cases of OSMF in pediatric patients were found. The youngest patient reported to be diagnosed with OSMF was of 2.5 years of age. Female preponderance was noticed. All the patients had the habit of areca nut chewing which subsequently led to fibrosis.

CONCLUSION

Such a rapid increase in the rate of OSMF among pediatric population is a potential danger to the society. The habit of areca nut chewing is the major cause for this dreadful condition. Lack of health consciousness and low level of education are the major factors for initiation of this habit among children. Therefore it is imperative for the parents and school as well as government authorities to take serious actions.

Oral submucous fibrosis: A clinicopathological study of 674 cases in China

BACKGROUND

Oral submucous fibrosis (OSF) has been reported frequently in India and other countries in South Asia. There are few reports on the clinicopathological features of OSF in China, where OSF is an epidemic. This study analyses the clinicopathological features of OSF in Hunan Province, China.

METHODS

A total of 674 cases of OSF were collected from July 2013 to August 2018 in Xiangya Stomatological Hospital, Central South University, and gender, age, site, pathological stage, habits, symptoms and associated lesions were recorded.

RESULTS

The male to female ratio was 32.7:1. The average age was 35.23 ± 10.08. The buccal mucosa was the most common site. A total of 99.85% of OSF cases chewed areca nut. Pale mucosa, restricted mouth opening, burning and fibrous bands were common clinical manifestations. Oral leukoplakia (OLK) was the most common associated lesion. The extended duration of chewing areca nut increased the risk of associated lesions (P < 0.05). The risk of OSF associated with OLK decreased with increasing OSF stage (P < 0.05).

CONCLUSION

The prevalence of OSF in males was higher than that in females, the buccal mucosa was most affected, and chewing areca nut is the most common habit of OSF patients.

Oral submucous fibrosis in a school-going Indian adolescent boy

A 14-year-old boy presented to our hospital with a chief complaint of difficulty in opening his mouth and a burning sensation on eating spicy food. The oral mucosa showed generalized diffused blanching and he was unable to protrude his tongue. For 6 years he had habitually chewed gutkha - a mixture of betel nut and tobacco for several minutes a day. This oral submucous fibrosis condition is very rare in young patients. The case highlights the link between oral submucous fibrosis and the regular use of areca nut (gutkha) products in a young boy.

Trismus in the paediatric population

Trismus is a rare presentation affecting neonates, children, and adults. In newborns there are serious implications, with potential to affect feeding, cause airway problems, and make intubation difficult. Causes of trismus seen in the paediatric patient are discussed in this review article; they are divided into intra- and extra-articular types. The extra-articular group consists of congenital and acquired disorders. The acquired group includes infective causes such as tetanus, iatrogenic causes related to drugs, cancer or dental treatment, and trauma causing articulation difficulty or triggering a rare type of bone growth in myositis ossificans. Changes in the mouth resulting from oral submucous fibrosis can undergo malignant transformation. This review aims to raise awareness of potential causes of trismus in paediatric populations, helping clinicians identify the underlying pathology so appropriate strategies for treatment be applied, with the ultimate aim of improving long-term outlook and quality of life for affected children.

Evaluation of plasma fibrinogen degradation products and total serum protein concentration in oral submucous fibrosis

BACKGROUND

Oral submucous fibrosis (OSMF) is a potentially malignant disorder with a multifactorial etiology. Malnutrition is a major problem for the inhabitants of most countries where OSMF is prevalent. Recently, a new direction in the etiopathogenesis was provided by the identification of fibrinogen degradation products (FDP) in the plasma of OSMF patients.

AIMS AND OBJECTIVES

To assess the role of FDP in the etiology of OSMF and to correlate with the nutritional status by evaluating the total serum protein level. The study also determines to evaluate the correlation between the levels of plasma FDP with respect to the staging and grading of OSMF. Correlation between the levels of Total Serum Protein (TSP) with respect to the staging and grading of OSMF was also evaluated.

MATERIALS AND METHODS

The study included 30 cases clinically and histopathologically diagnosed as oral submucous fibrosis. The FDP levels were assessed using both qualitative and semi quantitative method as supplied by 'Tulip Diagnostics (P) Ltd. Total Serum Protein (TSP) estimation was done by Biuret method using Liquixx Protein kit by Erba, Manheim.

RESULTS

The study indicates that in qualitative assessment of FDP only 14 subjects showed the presence of FDP levels>200ng/ml. In semiquantitative assessment there is no significant association between varying clinical stages and histopathological grades and FDP levels. Total serum Protein level showed a marginal increase in all subjects. The study revealed a positive correlation between FDP and TSP in all OSMF subjects.

CONCLUSION

A larger sample size which would be a better representation of the population and the use of different methods which have higher sensitivities and specificities to evaluate FDP level and detailed fractional analysis of protein along with immunoglobulin profiling would facilitate in attaining more conclusive results.

Assessment of oral mucosal lesions among psychiatric inmates residing in central jail, Bhopal, Madhya Pradesh, India: A cross-sectional survey

AIM

The aim of the current cross-sectional study was to assess oral mucosal lesions among psychiatric jail patients residing in central jail, Bhopal, Madhya Pradesh, India.

MATERIALS AND METHODS

The study subjects consisted of prediagnosed psychiatric patients residing in central jail, Bhopal. A matched control consisting of cross section of the population, that is, jail inmates residing in the same central jail locality was also examined to compare the psychiatric subjects. The WHO oral health assessment proforma, 1997 along with 18-item questionnaire was used for the oral health examination.

RESULTS

A total number of subjects examined were 244, which comprised of 122 psychiatric inmates and 122 nonpsychiatric inmates. Among all psychiatric inmates, about 57.4% of inmates had a diagnosis of depression, 14.8% had psychotic disorders (like schizophrenia), and 12.3% had anxiety disorder. A total of 77% study inmates, which comprised of 87.7% psychiatrics and 66.4% nonpsychiatrics had a habit of tobacco consumption (smokeless or smoking). Overall prevalence of oral mucosal lesions among the inmates was 85 (34.8%), which comprised of 39.3% psychiatric inmates and 30.3% nonpsychiatric inmates.

CONCLUSION

The information presented in this study adds to our understanding of the common oral mucosal lesions occurring in a psychiatric inmate population. Leukoplakia and oral submucous fibrosis were the most common types of oral mucosal lesions found. Efforts to increase patient awareness of the oral effects of tobacco use and to eliminate the habit are needed to improve oral and general health of the prison population.

Oral submucous fibrosis: a premalignant condition in a 14-year-old Indian girl

A 14-year-old Indian girl presented with difficulty in mouth opening and burning sensation while eating. On examination, blanching of the oral mucosa with diffuse white pigmented lesion of size 3.5 to 2 cm along with melanotic pigmentation was seen on the left buccal mucosa posteriorly. The patient was diagnosed with oral submucous fibrosis. A comprehensive treatment plan was made based on conservative management that included motivation and intense counselling of the patient and her parents so that she quits the habit of chewing areca nut and tobacco, along with systemic treatment of vitamin B complex supplements, antioxidants, multivitamins and oral physiotherapy. We present this case to highlight the difficulties faced by the clinical practitioners in providing treatment because of the taboos and myths associated with surgical treatment modality in rural population as well as to emphasise the menace of increasing consumption and availability of tobacco and areca nut to children.

Endodontic management of a patient with oral submucous fibrosis using custom modified endodontic instruments

This case report presents the endodontic management of a patient diagnosed with oral submucous fibrosis (OSMF), and with a reduced mouth opening of 18 mm. The patient presented with acute pain; and, emergency pulpectomy was performed using modified endodontic instruments. Treatment of OSMF was initiated and the endodontic treatment was completed at a late stage. The article discusses in brief the etio-pathogenesis of OSMF with endodontic management of such patients.

Oral submucous fibrosis in a 9-year-old Indian girl

Oral submucous fibrosis (OSMF) is a premalignant condition strongly associated with the practice of chewing areca nut, a habit common among South Asian population. It is characterised by inflammation, increased deposition of submucosal collagen and formation of fibrotic bands in the oral and paraoral tissues, which increasingly limit mouth opening. A case of OSMF occurring in a 9-year-old Indian girl is presented. This paper discusses the aetiology, clinical presentation and treatment modalities of oral submucous fibrosis.

Depigmentation of oral mucosa as the earliest possible manifestation of oral submucous fibrosis in Sri Lankan preschool children

This article reports the presentation of oral submucous fibrosis in five Sri Lankan preschool children, aged 2-3 years, with loss of pigmentation of the lips as the sole clinical feature. Oral submucous fibrosis has not been reported in this age group of children. The five 2-3 year olds did not display any classical features of oral submucous fibrosis, due to the disease having been detected at a very early stage. The present study attempts to establish that depigmentation of the lips and oral mucosa is perhaps the earliest feature to develop in the natural history of oral submucous fibrosis. The differential diagnosis of oral mucosal depigmentation relevant to these cases is also discussed. Previously-reported cases of oral submucous fibrosis in children are reviewed.

Comparative study between the Hybrid Capture II test and PCR based assay for the detection of human papillomavirus DNA in oral submucous fibrosis and oral squamous cell carcinoma

Background

Oral malignancy is a major global health problem. Besides the main risk factors of tobacco, smoking and alcohol, infection by human papillomavirus (HPV) and genetic alterations are likely to play an important role in these lesions. The purpose of this study was to compare the efficacy of HC-II assay and PCR for the detection of specific HPV type (HPV 16 E6) in OSMF and OSCC cases as well as find out the prevalence of the high risk HPV (HR-HPV) in these lesions.

Methods and materials

Four hundred and thirty patients of the potentially malignant and malignant oral lesions were taken from the Department of Otorhinolaryngology, Moti Lal Nehru Medical College, Allahabad, India from Sept 2007-March 2010. Of which 208 cases were oral submucous fibrosis (OSMF) and 222 cases were oral squamous cell carcinoma (OSCC). The HC-II assay and PCR were used for the detection of HR-HPV DNA.

Result

The overall prevalence of HR-HPV 16 E6 DNA positivity was nearly 26% by PCR and 27.4% by the HC-II assay in case of potentially malignant disorder of the oral lesions such as OSMF. However, in case of malignant oral lesions such as OSCC, 32.4% HPV 16 E6 positive by PCR and 31.4% by the HC-II assay. In case of OSMF, the two test gave concordant result for 42 positive samples and 154 negative samples, with an overall level of agreement of 85.4% (Cohen's kappa = 66.83%, 95% CI 0.553-0.783). The sensitivity and specificity of the test were 73.7% and 92.05% (p < 0.00). In case of OSCC, the two test gave concordant result for 61 positive samples and 152 negative samples, with an overall level of agreement of 88.3% (Cohen's kappa = 79.29, 95% CI 0.769-0.939) and the sensitivity and specificity of the test were 87.14% and 92.76% (p < 0.00).

Conclusion

This study concluded that slight difference was found between the positivity rate of HR-HPV infection detected by the HC-II and PCR assay in OSMF and OSCC cases and the HC II assay seemed to have better sensitivity in case of OSCC.

Lipid profile in oral submucous fibrosis

BACKGROUND

Changes in lipid profile have long been associated with malignancies as lipids play a key role in maintenance of cell integrity. This study evaluated the alterations in extended lipid profile in untreated patients of oral submucous fibrosis (OSMF) and studied the correlation between lipid levels with tobacco consumption.

MATERIALS AND METHODS

In this hospital-based study, 65 clinically diagnosed and histopathologically proven patients of OSMF and 42 age and sex matched controls were studied. In these samples serum lipids including: (i) Total cholesterol, (ii) LDL cholesterol (LDLC), (iii) HDL cholesterol (HDLC) (iv) VLDL cholesterol (VLDLC) (v) triglycerides (vi) Apo-A1 (viii) Apo-B and (viii) LPa were analyzed.

RESULTS

A significant decrease in plasma total cholesterol, HDLC and Apo-A1 was observed in patients with OSMF as compared to the controls. Thus an inverse relationship between plasma lipid levels and patients was found in OSMF.

CONCLUSION

The lower levels of plasma cholesterol and other lipid constituents in patients might be due to their increased utilization. The findings strongly warrant an in-depth study of alterations in plasma lipid profile in patients with oral precancerous conditions.

A new matrix for analyzing low molecular mass compounds and its application for determination of carcinogenic areca alkaloids by matrix-assisted laser desorption ionization time-of-flight mass spectrometry

Arecoline is the main alkaloid present in the areca nut (or betel nut) and it has central nervous system effects. Its pharmacological activities induce the constriction of the bronchial smooth muscles, and stimulation of the lacrimal and intestinal glands. Chewing areca nut is harmful to health because this habit may increase the risk of the development of oral cancer. In this study, a fast method was provided for the determination of areca alkaloids by matrix-assisted laser desorption ionization (MALDI) mass spectrometer with a time-of-flight (TOF) analyzer. Traditionally the MALDI-TOF method was not suitable for the analysis of small molecular weight (m/z<600) compounds because of the high background of the matrix. In this study, a new matrix was utilized to decrease the background interference effectively. After simple sample preparation, 1 microL sample supernatant was mixed with 1 microL matrix and then deposited on the target plate. This new matrix was also used to test the MALDI imaging experiment. Application of this MALDI-TOF method for trace analysis of arecoline by this new matrix in human plasma at sub microM level proved workable.

[Oral submucous fibrosis in a 31-year-old Indian women: first case report from Germany]

BACKGROUND

Oral submucous fibrosis (OSF) is a chronic disease characterized by subepithelial collagen deposition with formation of bands involving the oral cavity and adjacent structures. Oral submucous fibrosis is a precancerous condition. It is caused by chewing of betel quid (Areca catechu L., Piper betle, lime and tobacco) and ready-made products like pan masala and gutka which also contain areca nut. These products are available all over South Asia. The hallmark of OSF is extremely restricted mouth opening.

CASE REPORT

A 31-year-old Indian woman who has lived in Germany since 1997 presented herself because of limitation of mouth opening. She reported that she has chewed pan masala and gutka since she was 17 years of age. History, clinical and histological findings clearly pointed to the diagnosis of OSF.

DISCUSSION

Conservative as well as surgical interventions for OSF have not resulted in adequate long-term results. Since OSF may occur in children and young adults, the primary aim should be to avoid progression of the disease, initially by physiotherapy. Surgical interventions should not be applied at an early stage of the disease because recurrences and further surgical interventions are often necessary. Due to the increasing numbers of migrants from South Asia more cases of OSF will probably also be observed in Germany, where areca nut-containing products are also available.

The Chewing of Betel Quid and Oral Submucous Fibrosis and Anesthesia

Oral submucous fibrosis (OSMF) is a premalignant lesion of the buccal mucosa caused by chewing betel quid. It results in progressive inability to open the mouth. OSMF causes difficulty in laryngoscopy and intubation of the trachea. Patients with OSMF require anesthesia for trismus correction, resection, and reconstructive (oncoplastic) surgery for coexisting oral malignancies or other unrelated surgeries. Our review of the anesthetics of 44 patients with oral malignancies suggested that 8 had OSMF. The preoperative airway assessment, including the Mallampati score and the clinical Tumor Node Metastasis stage, were useful in predicting the need for fiberoptic intubation. Patients with oral malignancies and OSMF had increased requirement for fiberoptic endotracheal intubations (62.5%) compared with those without OSMF (44.4%). Three different techniques of airway management (tracheal intubation after direct laryngoscopy, fiberoptic tracheal intubation, and tracheostomy) in four patients with OSMF are described. OSMF contributes to the development of the malignancy, delays the diagnoses, and complicates the anesthetic management.

High-performance liquid chromatographic determination of arecoline in human saliva

Arecoline (methyl-1,2,5,6-tetrahydro-1-methyl nicotinate) is an alkaloid found in the areca catechu nut which is a major component of the 'betel quid' chewed by a large proporation of the population in India, South Asia and the South Pacific islands. It is commonly associated with the development of oral leukoplakia, oral submucous fibrosis and oral cancer. We have developed a new ion-pairing reversed-phase high-performance liquid chromatographic (HPLC) method for the determination of arecoline in saliva, using arecaidine (1,2,5,6-tetrahydro-1-methylnicotinic acid) as an internal standard. The optimal wavelength was established using UV absorbance scans. It was showed that 215 nm is the optimal wavelength to maximise the signal in detecting arecoline in the mobile phase. Arecoline was extracted from saliva with hexane-isoamyl alcohol (1%) and reconstituted with mobile phase for HPLC analysis. The developed method is an easy and reliable method of determining arecoline concentrations in saliva. Sensitivity, specificity, precision, accuracy and reproducibility of the method were demonstrated to be satisfactory for measuring the arecoline level.
