Oral findings in three different groups of immunocompromised patients

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 4 2000
Ulrich Meyer
Abstract: The objective of this study was to determine the frequency of oral, dental and periodontal findings in three different groups of immunocompromised patients and in a healthy control group, to evaluate whether there is a correlation between manifestations of disease and immunologic parameters. The survey included 46 patients with a diagnosis of systemic lupus erythematosus, 48 heart transplant recipients, and 53 adult patients suffering from acute leukemias. Fifty matched healthy subjects were used as a control group. Each patient had to answer questions on medical and dental health and underwent a thorough oral, dental and serological investigation. Oral mucosal lesions were found in nearly half of all immunocompromised patients (49.6%), but in only 26% of control patients. No significant associations were found between different types of oral lesions and the underlying cause of immunosuppression. Leukemia patients showed age-unrelated higher scores in periodontal indices (P<0.05). Laboratory parameters failed to be significant in the assessment of oral health. [source]

doi:10.1111/j.1741-2358.2009.00313.x Prevalence of oral and dental disorders in institutionalised elderly people in Rasht, Iran Objective:, The aim of this study was to determine the prevalence of dental and oral mucosal lesions in institutionalised elderly people in Rasht. Background:, Oral health in the elderly people is important to tailor the health programmes for this increasing age group within the population. Methods:, A total of 216 elderly people residing in a geriatric nursing home were included in the study. Subjects were interviewed and examined clinically and registered in a data collection form and analysed using spss version 11 program (SPSS Inc, Chicago, Illinois, USA). Results:, The prevalence of dental and oral disorders was 44.9% and 86.1% respectively. The most frequent oral disorders were dry mouth (42.1%), fissure tongue (25.9%), atrophic of tongue (25%), sublingual varicosity (22.7%), burning sensation (16.7%) and varix (15.3%). The prevalence of edentulousness was 56% (95%CI: 49,63%). The mean level of retained teeth was 3.22. The odds of an oral mucosal disorder in females were significantly more than in males (OR = 2.79, 95%CI: 1.25,6.23). Discussion:, The findings revealed a high prevalence of dental and oral disorders in institutionalised elderly people in Rasht in comparison to similar studies. The mean of retained teeth was also much lower than in other reports. Therefore, the necessity for regular oral examination of these rapidly expanding age groups of people is essential. [source]


Mucous membrane pemphigoid, thymoma, and myasthenia gravis

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 9 2000

In November 1997, approximately 1 year before being evaluated at the Mayo Clinic, Rochester, a 63-year-old woman presented with erosive tongue lesions that were diagnosed by her physician as oral lichen planus. The lesions responded well to 3 months of treatment with systemic and topical corticosteroids and topical antiyeast medication. She stopped taking the medications and had a relapse. A few months after the oral lesions developed, her left eyelid became ptotic. Results of magnetic resonance imaging of her brain were normal, and the ptosis resolved spontaneously after 2 weeks. One year later, her right eyelid began to droop, and the results of edrophonium testing were positive. She was prescribed prednisone, 30 mg daily, and pyridostigmine, as needed. The ptosis improved, but never fully resolved. Radiography revealed a left ,,thyroid nodule,'' but computed tomography did not show a mediastinal mass. She was advised to have the ,,nodule'' removed surgically and came to the Mayo Clinic, Rochester, for a second opinion. Her medical history was significant for the following: tinnitus, glaucoma, early bilateral cataracts, and long-standing hypertension, for which she took losartan, 50 mg twice daily. Other medications included: prednisone, 30 mg daily; pyridostigmine as needed; famotidine, 40 mg daily; and eyedrops for glaucoma. She denied any history of hyperthyroidism or hypothyroidism, head and neck irradiation, family history of thyroid disease, or diplopia. Hepatitis serologic studies revealed hepatitis B exposure and recovery, hepatitis C immunity, and a previous hepatitis A viral infection. On examination at the Mayo Clinic, Rochester, an erosive hypertrophic plaque was noted on the posterior dorsal half of the tongue, and vesicles and erythematous erosions on the hard and soft palates ( Fig. 1a). A lace-like white pattern was seen on the buccal mucosa bilaterally, and a small erosive patch on the left buccal mucosa ( Fig. 1b). Ocular and nasal mucous membranes were normal in appearance, and there were no pertinent skin findings. Dermatopathologic examination of an excisional biopsy specimen from the left dorsum of the tongue demonstrated an ulcer with epitheliomatous hyperplasia and a granulomatous reaction, presumably due to yeast infection. Silver staining showed hyphae and yeast at the base of the tongue ulcer. The results of the direct immunofluorescence study were negative and revealed no lichenoid changes on hematoxylin and eosin staining. Indirect immunofluorescence testing of the serum revealed a 1 : 80 titer of basement membrane zone antibodies, reflecting pemphigoid. This test was positive on repeat study. Salt-split skin on monkey esophagus revealed an epidermal pattern of basement membrane zone antibodies. Treatment included fluocinonide gel applied to the involved areas four times daily and oral antiyeast therapy (fluconazole, 200 mg once daily by mouth) while the rest of the evaluation was being completed. Figure 1(a). Erosive hypertrophic tongue plaque. Figure (b) ,. Erosive patch on the buccal mucosa. As part of the evaluation of the ptosis, a myasthenia gravis antibody panel was performed. It revealed the following abnormalities: striated muscle antibody at 1 : 480 (reference range, <1 : 60), acetylcholine receptor binding antibody at 6.33 nmol/L (reference range, ,,0.02 nmol/L), acetylcholine receptor blocking antibody at 31% (reference range, 0,25%), and acetylcholine receptor modulating antibody at 100% (reference range, 0,20%), suggesting thymoma. Treatment included pyridostigmine, 30,45 mg 3,4 times daily, to control the myasthenia symptoms, while the ill-defined neck mass was being evaluated. A mildly enlarged thyroid was noted on physical examination. Hematology panel revealed thyroid-stimulating hormone (TSH) levels in the low normal range; the thyroid microsomal antibody was normal. Chest radiography showed minor tracheal deviation, and a previous computed tomogram showed what appeared to be a 3-cm enlarged mass in the thyroid. Ultrasonographically guided thyroid biopsy did not show malignancy, but a benign mesenchymal-type tumor was found and surgical excision was planned. Intraoperatively, a thymoma of the left cervical thymic tongue was found. At 6 months' follow-up, the ptosis and oral mucosal lesions had improved significantly, although she continued topical corticosteroid therapy intermittently for minor erosive oral disease. [source]

INTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 5 2010
RENNAN Y. DU
International Journal of Paediatric Dentistry 2010; 20: 330,335 Objectives., To assess and compare the oral health status of preschool children with and without cerebral palsy (CP). Methods., Preschool children with CP (72) were recruited from 23 Special Child Care Centers in Hong Kong. An age (±3 months) and gender matched sample of preschool children from mainstream preschools were recruited as the control group. Dental caries status, gingival health status, tooth wear, developmental defect of enamel, malocclusion, dental trauma and oral mucosal health were assessed and compared between the two groups. Results., Significant differences in gingival health status were found between children with and without CP (mean plaque index scores, P = 0.001 and mean gingival index scores, P < 0.05). Tooth wear involving dentine was more prevalent among CP children (P < 0.001), as were evidence of anterior open-bite (P < 0.001) and oral mucosal lesions (P < 0.05). Children with and without CP had similar caries experiences (P > 0.05), prevalence of enamel defects (P > 0.05) and dental trauma (P > 0.05). Conclusions., Differences of oral health status exist among preschool children with and without CP. Preschool children fare worse in terms of gingival health, tooth wear, oral mucosal health and malocclusion. [source]


Zinc deficiency may be a cause of burning mouth syndrome as zinc replacement therapy has therapeutic effects

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 9 2010
Gye Song Cho
J Oral Pathol Med (2010) 39: 722,727 Background:, Zinc is known to play an important role for growth and development, the immune response, neurological function, and reproduction. Although the etiology of burning mouth syndrome (BMS) is unknown, zinc deficiency may be implicated in the pathogenesis of BMS. The aim of this study was to demonstrate a causal relationship between zinc deficiency and BMS and to assess whether zinc replacement is an effective therapy for BMS. Methods:, Serum zinc level was evaluated in 276 patients with BMS. To assess the therapeutic effect of zinc replacement, patients with zinc deficiency were administered a zinc supplement (14.1 mg/day). Pain intensity 6 months after zinc replacement was evaluated using an 11-point numerical scale. We also developed an animal model of zinc deficiency to assess the effects of zinc deficiency on the oral mucosa. Results:, Of the 276 patients with BMS, 74 (26.8%) had low serum zinc levels. Zinc replacement therapy lowered the mean numerical pain scale in these patients from 8.1 to 4.1, compared with a mean decrease from 7.7 to 6.7 in a control group (P = 0.004). In our animal model of zinc deficiency, the main pathologic findings were hyperkeratinization and increased mitosis on the dorsum of the tongue, although there were no gross oral mucosal lesions. Conclusions:, Zinc deficiency might play a role in some patients with BMS. In such patients, appropriate zinc replacement therapy is effective in relieving symptoms. [source]

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 10 2003
I. Espinoza
Abstract Background:, Oral prevalence studies are important to know the state of health and the needs of treatment. Our aim was to determine the prevalence of oral mucosal lesions and associated factors among aging Chileans. Methods:, A random sample by age, gender, and socioeconomic status was obtained, comprising 889 individuals older than 65 years. Individuals were interviewed and examined in Santiago, the capital of Chile, according to the World Health Organization guidelines. Results:, The prevalence of one or more oral mucosal lesions in the sample was 53%. Logistic regression model revealed that denture use increased the probability of one or more oral mucosal lesions by threefold, while age, gender, smoking, medication use, xerostomia, and social or cultural factors had no effect. The most common lesion was denture stomatitis (22.3%), followed by irritative hyperplasia (9.4%), oral mucosal varicosities (9%), solitary pigmented lesions (4%), traumatic ulcer (3.5%), angular cheilitis (2.9%), multiple pigmented lesions (2.8%), hemangioma (2.3%), lichen planus (2.1%), leukoplakia (1.7%), recurrent aphthous stomatitis (1.4%), nicotine stomatitis (1.3%), median rhomboid glossitis (0.9%), actinic cheilitis (0.9%), pyogenic granuloma (0.7%), oral squamous papiloma (0.6%), and mucocele (0.2%). One case of oral cancer was observed. Different factors increased the probability of specific oral mucosal pathologies. Conclusions:, We can conclude that oral mucosal lesions are common in elderly people in Santiago, suggesting the necessity for improved standards of prevention, and diagnostic and opportune treatment of these lesions.

Oral pre-cancer and the associated risk factors among industrial workers in Japan's overseas enterprises in the UK

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 5 2003
Toru Nagao
Abstract Background: ,Screening at industries has been advocated as a method of early detection for cancer. This study describes the prevalence of oral pre-cancerous lesions and other mucosal diseases following oral mucosal screening, and associated risk factors among Japanese industrial workers in the UK. Methods: ,Oral mucosal screening was by invitation at 51 industrial locations in the UK. A self-administered questionnaire was used to record socio-behavioural factors and frequency of daily intake of fruits and vegetables. Results: ,Four hundred and eighty-four subjects attended for oral mucosal screening (mean age 39.9 ± 8.3 years) and their mean period of residence in UK was 5.3 ± 4.5 years. 63.4% examined were male. 31.3% of males and 26.6% of females smoked daily. The gender differences were striking compared with Japan's national rates. A higher proportion of managerial staff was regular heavy (20+ per day) smokers. The intake of more than five portions per day of vegetables and/or fruits during the weekend was significantly higher in females than in males (P = 0.022). One hundred and six subjects (22%) were detected with oral mucosal lesions, including 16 leukoplakia lesions (3.3%) and three with oral lichen planus (1%). The rate of positive detections was higher in managers (7.5%). Odds ratios were estimated by socio-behavioural variables. Among subjects positive for oral leukoplakia, managers accounted for 68.8% (OR 5.26; 95% CI, 1.24,22.29). 87.5% of subjects detected with oral leukoplakia smoked daily and had done so for the past 10 years (OR 28.40; 95% CI, 5.63,143.28). Though regular alcohol drinking was a common feature among male leukoplakia cases, heavy alcohol misuse was not encountered. None reported an intake of five or more portions of fruits or vegetables. Conclusions: ,The Japanese nationals working in managerial positions in the UK and daily regular smokers in the industries visited were found to be at a high risk of oral pre-cancer. Regular dental/oral check up and tobacco education programmes are encouraged for oral cancer/pre-cancer control in industrial settings. [source]


Proliferation and differentation markers in snuff-induced oral mucosal lesions

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 5 2002
Marina Merne
Abstract Background: Regular use of snuff is known to cause whitish oral mucosal lesions of variable severity at the usual quid placement site. The main aim of this study was to elucidate cellular mechanisms involved in snuff-induced epithelial changes. Methods: Expression patterns for markers of cell proliferation (PCNA, Ki-67), cell cycle regulation (p53, p21), keratin changes (pankeratin, CK18, CK19), cell stress (HSP 70) and collagen type IV in 14 snuff-induced oral mucosal lesions and 12 control samples were analyzed by immunohistochemistry (IHC). Results: On light microscopy, all snuff-induced lesions were characterized by a hyperkeratinized and thickened epithelium. Some vacuolized cells, markers of cell degeneration, were frequently seen (in 9/14 of the samples) in the superficial layers in epithelia. Expression of PCNA and Ki-67 was found in a statistically significantly fewer cells in snuff-induced lesions (P < 0.001) than in the controls. This indicates that epithelia in snuff-induced lesions are not thickened as a result of increased cellular proliferation, but by protracted turnover of differentiating cells. Of cell cycle markers, p21 was found be up-regulated in 4/14 snuff-induced lesions, probably by p53-independent pathways. Only two snuff-induced lesions showed p53 positivity. However, the number of stained cells with p53 and p21 was not statistically different from that in controls. Expression of CK18, but not any alterations in CK19 expression, was seen in 5 of 14 snuff-induced lesions. Snuff also seems to stimulate the expression of collagen type IV, possibly by basal cells, as indicated by the thickened staining of the basal lamina. Conclusions: The findings of this study showing suppressed cellular proliferation and infrequent p53 dysfunction in snuff lesions may partly explain why dysplastic changes are seldom seen in mucosal lesions induced by the Scandinavian type of snuff.

Synergistic effects of nicotine on arecoline-induced cytotoxicity in human buccal mucosal fibroblasts

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 8 2001
Yu-Chao Chang
Abstract: Areca quid chewing has been linked to oral submucous fibrosis and oral cancer. Arecoline, a major areca nut alkaloid, is considered to be the most important etiologic factor in the areca nut. In order to elucidate the pathobiological effects of arecoline, cytotoxicity assays, cellular glutathione S-transferase (GST) activity and lipid peroxidation assay were employed to investigate cultured human buccal mucosal fibroblasts. To date, there is a large proportion of areca quid chewers who are also smokers. Furthermore, nicotine, the major product of cigarette smoking, was added to test how it modulated the cytotoxicity of arecoline. At a concentration higher than 50 ,g/ml, arecoline was shown to be cytotoxic to human buccal fibroblasts in a dose-dependent manner by the alamar blue dye colorimetric assay (P<0.05). In addition, arecoline significantly decreased GST activity in a dose-dependent manner (P<0.05). At concentrations of 100 ,g/ml and 400 ,g/ml, arecoline reduced GST activity about 21% and 46%, respectively, during a 24 h incubation period. However, arecoline at any test dose did not increase lipid peroxidation in the present human buccal fibroblast test system. The addition of extracellular nicotine acted synergistically on the arecoline-induced cytotoxicity. Arecoline at a concentration of 50 ,g/ml caused about 30% of cell death over the 24 h incubation period. However, 2.5 mM nicotine enhanced the cytotoxic response and caused about 50% of cell death on 50 ,g/ml arecoline-induced cytotoxicity. Taken together, arecoline may render human buccal mucosal fibroblasts more vulnerable to other reactive agents in cigarettes via GST reduction. The compounds of tobacco products may act synergistically in the pathogenesis of oral mucosal lesions in areca quid chewers. The data presented here may partly explain why patients who combined the habits of areca quid chewing and cigarette smoking are at greater risk of contracting oral cancer. [source]


Oral sensorial complaints, salivary flow rate and mucosal lesions in the institutionalized elderly

JOURNAL OF ORAL REHABILITATION, Issue 2 2010
I. GLAZAR
Summary, The aims of this study were to determine the prevalence of oral sensorial complaints, salivary flow rate and oral mucosal lesions in the institutionalized and non-institutionalized elderly. The study included 280 institutionalized and 61 non- institutionalized elderly people. Dry mouth, burning mouth sensations, taste disturbances, salivary flow rate and oral mucosal lesions were assessed and compared between groups. A greater number of the institutionalized elderly had dry mouth (P = 0·001) and taste disturbance (P = 0·035) compared to non-institutionalized elderly. The institutionalized elderly also had significantly lower salivary flow rate (P < 0·0001). Positive correlation was found between salivary flow rate and perception of dry mouth in the institutionalized elderly (rs = 0·26; P < 0·05), as well as in the non-institutionalized elderly (rs = 0·35; P < 0·05). Moreover, positive correlation was observed between salivary flow rate and the sensation of burning mouth in the institutionalized elderly (rs = 0·13; P < 0·05) and non-institutionalized elderly (rs = 0·31; P < 0·05). The number of institutionalized elderly people with oral mucosal diseases was higher compared with non-institutionalized ones (P = 0·01). The most common oral mucosal lesions in both groups were related to wearing dentures. It can be concluded that the institutionalized elderly are significantly affected with oral sensorial complaints, including dry mouth and taste disturbance, as well as decreased salivary flow rate and oral mucosal diseases compared with the non-institutionalized elderly.

Oral and Maxillofacial Pathology: Bcl-2 expression in sequential biopsies of potentially malignant oral mucosal lesions assessed by immunocytochemistry

ORAL DISEASES, Issue 5 2000
RL McAlinden
OBJECTIVE: To examine, for the first time Bcl-2 expression in sequential (autogenous) oral mucosal biopsies taken from the same sites in a gender, risk-factor matched, Caucasoid sample, over a 21-year period. DESIGN: Retrospective immunocytochemical longitudinal study of archival serial biopsies. MATERIALS AND METHODS: Computer records were used to identify biopsy specimens derived from 12 patients. These were divided into four groups: (1) Histologically innocuous lesions which remained histologically innocuous. (2) Dysplastic lesions which remained dysplastic. (3) Histologically innocuous lesions which later progressed to squamous cell carcinoma (SCC). (4) Dysplastic lesions which later progressed to SCC. This represented 65 biopsies in total. Bcl-2 expression was studied using mouse antihuman BCL-2 oncoprotein clone 124 (Dako, Denmark). RESULTS: Generally, there was a lack of Bcl-2 immuno-reactivity in the epithelium, with one exception in dysplastic epithelium from a group (3) patient. CONCLUSION: These findings suggest that in our series, Bcl-2 is not expressed early in oral premalignant lesions and appears to contradict previous reports. Possible explanations for this disparity are considered. [source]


Oral mucosal malignancy and potentially malignant lesions: an update on the epidemiology, risk factors, diagnosis and management

AUSTRALIAN DENTAL JOURNAL, Issue 2010
MJ McCullough
Abstract An oral examination for the assessment for malignant and potentially malignant oral mucosal lesions is routine in general dental practice. It may be uncommon for general dental practitioners to encounter oral cancer, with anecdotal reports suggesting that this occurs about once every 10 years in a busy general dental practice. However, potentially malignant oral mucosal lesions are relatively common, occurring in about 2.5% of the population. This update highlights the epidemiology, risk factors, diagnosis and management of these oral mucosal lesions. [source]


Darier's disease in Singapore

BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2005
B.K. Goh
Summary Background, Darier's disease is a rare, dominantly inherited genodermatosis. Although it has been well studied in caucasians, very little is known about the clinical spectrum of this disorder among Asians. Objectives, To determine the demographic and clinical profile of Asian patients with Darier's disease. Methods, This is a retrospective study of all new cases of Darier's disease seen in our centre over a 20-year period (1982,2002). Results, Twenty-four nonrelated cases of Darier's disease were studied. The incidence rate was 3·1 per million per decade. The gender distribution was 19 males and five females, and the ethnic origin was 21 Chinese, two Malays and one Nepalese. The peak age of onset was between 11 and 20 years. Sun exposure exacerbated the disease in 13 of the patients, and three had neuropsychiatric disorders. The disease affected predominantly seborrhoeic areas in 19 patients, flexural in three, acral in one and was segmental in one patient. Hand involvement was common and included palmar pits in nine patients, acrokeratosis verruciformis in four and nail changes in 12 patients. Haemorrhagic macules were not seen. Rare features included oral mucosal lesions (two patients) and guttate leucoderma (three patients). Pathogens involved in cutaneous infections included herpes simplex virus, Staphylococcus aureus, Streptococcus species and Morganella morgani. All patients treated with oral retinoids had improvement of clinical signs. In contrast, the response to topical retinoids was poor. Conclusions, Compared with western studies, our results show a similar incidence rate, age of onset, distribution of disease patterns and association with neuropsychiatric disorders. Features that differ include co-occurrence of guttate leucoderma, rarity of acrokeratosis, absence of haemorrhagic macules and poor response to topical retinoids. [source]


Recurrent herpes labialis in US children and youth

COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 6 2004
Jay D. Shulman
Abstract , Objective:, This study reports data from the Third National Health and Nutrition Examination Study, 1988,1994 (NHANES III). Methods:, NHANES III was a complex, multistage sample of 33 994 civilian, non-institutional individuals from 19 528 households. Dentist examiners were trained to recognize, classify oral mucosal lesions to include recurrent herpes labialis (RHL). Subjects ,8 years of age were asked if they had cold sores in the past year and serologic tests for herpes virus type 1 (HSV-1) and type 2 (HSV-2) were performed on blood of youth >12 years of age. Results:, Examinations were performed on 10 032 individuals 2,17 years of age. Overall point prevalence was 1.42% (0.69,2.15); annual prevalence in individuals 8,17 years of age was 14.77% (12.74,16.80); and serologic prevalence of HSV-1 in youth 12,17 years of age was 43.18% (38.88,47.48). When the data were subset to youth 12,17, annual prevalence for seropositives was 24.13% (20.44,27.82) compared with 16.87 (14.16,19.57) for all subjects. Approximately 25% of the seropositive youth had at least one recurrence in the past year. Conclusion:, As RHL is a recurrent infection, prevalence in a population will be related to the proportion of the population that has been infected with herpes simplex virus. When lesion-specific prevalences are cited in the literature, they should be stratified by covariates known to be associated with them. Future studies should examine RHL prevalence in infected individuals. [source]
