THE MOST COMMON DISEASES OF ORAL MUCOSA IN GERIATRIC PATIENTS. DIAGNOSIS AND TREATMENT. AGE CHANGES : Changes in oral mucosa structure Decrease of saliva secretion due to increasing amount of fat cells,lymphocytes and fibrosis in all salivary glands decrease of immunity systemic diseases more catabolic than anabolic processes lek.dent Monika Hemerling AGE CHANGES IN ORAL MUCOSA : stratum corneum- increase of ortokeratosis → risk of planoepitelioma cancers • In geriatric patients oral mucosa becomes pale, atrophic and more prone to mecanical, chemical and bacterial reactions . stratum spinosum – reduction of thickness → frequent ulcerations basal layer- hyperactivity of melanocytes → dark pigmentation • The inflammation lasts longer, clinical symptoms might be less intensive but there is a higher risk of complications. submucsal membrane - reduction of elastic fibres LEUKOPLAKIA Currently defined as a predominantly white lesion of the oral mucosa that cannot be characterized as any other definable lession. Etiology : Tabacco Alcohol abusement Vitamines deficiency (A,B) Chronic irritation (chronic cheek biting, ill-fitting dentures, sharp teeth) 1 WHO division of leukoplakia : a) homogeneous Three clinical stages of leukoplakia I. The earliest lesion is nonpalpable, faintly translucent, and has white discoloration. b) non-homogenous 1. Erythroleukoplakia 2. Verrucous leukoplakia 3. Speckled leukoplakia II. Localized or diffuse, slightly elevated plaques with an irregular outline develop. These lesions are opaque white and may have a fine, granular texture. III. In some instances, the lesions progress to thickened, white lesions, showing induration, fissuring, and ulcer formation. Clinical criteria demonstrate a particularly Localization : • Buccal mucosa ( commisure) • Hard palate • Lateral and ventral tongue • Floor of mouth high risk of malignant change : The verrucous type is considered high risk. Erosion or ulceration within the lesion is highly suggestive of malignancy. The presence of a nodule indicates malignant potential. Leukoplakia of the anterior floor of the mouth and undersurface of the tongue is strongly associated with malignant potential. Differential diagnosis : • Lichen planus • Hyperplastic candidiosis • Chemical/ termal burn • White sponge nevus • Leukoedema • Linea Alba Treatment : Discontinue the use of tabacco and alcohol Topical retinoids Excision modalities : surgery, cryotherapy, carbon dioxide laser, 2 LICHEN PLANUS Clinical variants of oral lichen planus: • Skin and oral mucosa disease of unknown etiology (autoimmunological or immunological factors?) Reticular ( Wickham’s striae) Plaque-like Papular Atrophic • It occures in fourth to eighth decade, more often among females (60%). • Nervous and susceptible people are more prone to develope lichen planus. Erosive (ulcerative) • The oral lesions may form before, after or at the same time as the skin lesions. Clinical presentation : bilateral and often symmetric distribution buccal mucosa (most common) tongue gingivae lips Differential diagnosis : Leukoplakia ( Shiller’s test) Lupus erythematosus Lichenoid drug eruption Ertyhema multiforme Reticular, plaque –like and papular variants tend to be asymptomatic, often noticed incidentally by the patient, although a sensation of ‘roughness’may be present. Both atrophic and erosive types are very painful and cause a lot of discomfort while speaking and eating. Atrophic lesions present as irregular areas of erythematous mucosa. Erosive eruptions are described as irregular areas of epithelial destruction, covered with a yellow fibrin. Geriatric patients often present extensive erosive lesions due to mucosa susceptibility to mechanical irritation. Treatment : topical corticosteroids (mild and moderate cases) Hydrocortison systemic immunosuppression (severe cases) Prednisolone, Ciclosporin antiseptics Chlorhexidine analgesics Lignocaine rinse retinoids 3 PEMPHIGUS Varieties of pemphigus : Immunobullous disorder that affects the skin and mucous membrane. It is characterized by the presence of autoantibodies to intercellular substance in the stratum spinosum of epitelium. The intraepitelial bullae are produced as a result of acantholysis - the brakedown of the intracellular connections. p. vulgaris p. vegetans p. erythematosus p. foliaceus Half of all initial lesions are found in the mouth. Oral lesions develop in 70% of cases. Clinical presentation : Pemphigus vulgaris is the most common variety in geriatic patients. It begins as fragile bullae that rapidly brake down with the formation of shallow, irregular and painful ulcers. Differential diagnosis : Pemphigoid – direct immunofluorescence(IMF) -antibodies at the stratum spinosum of affected epitelium Erosive lichen planus buccal mucosa lips palate tongue gingivae (desquamative gingivitis) Treatment : • Corticosteroids • systemic immunosuppression • antiseptics Erythema multiforme 4 PEMPHIGOID Subtypes of pemphigoid : • Bullous Pemphigoid ( BP) - predominantly affects the • Immunobullous disorder characterized by the formation of supepidermal bullae and the presence of immunoreactants at the basement skin and occasionally mucosa • Mucous Membrane Pemphigoid (MMP) – involves mucosa and occasionally skin membrane zone. The onset of MMP varies from under 30-70 years of age but is morre common in late middle to old age( 50-70 years age group) There is 2:1 preponderance of female patients Clinical presentation : supepidermal bullae may remain intact for number of days bullae are in general painless but there may be Differential diagnosis : Pemphigus vulgaris- direct immunofluorescence- antibodies at basement membrane zone discomfort while forming and after rupture ulcerations of buccal mucosa, palate, tongue, lips gingivae (desquamative gingivitis) Erythema multiforme Erosive lichen planus CANDIDIASIS : Treatment : topical corticosteroids Oral candidiasis is predominately caused by Candida albicans, although other related Candida species may be involved. Candida is a commensal organism and part of the normal oral flora in about 30% - 50% of the population. It is capable of producing opportunistic infections within the oral cavity when appropriate predisposing factors exist. 5 Predisposing factors in geriatric patients : Xerostomia Antibiotic therapy Corticosteroid therapy Poor oral or denture hygiene Malnutrition/Gastrointestinal malabsorption Iron, folic acid, or vitamin deficiencies Acidic saliva/Carbohydrate-rich diets Radiation therapy/Chemotherapy Diabetes mellitus and other systemic diseases The most common variant in elderly patient is Chronic Atrophic Candidiasis. It is often associated with a poorly fitting dentures and known as “denture - sore mouth”. Clinical Presentation : Differential diagnosis : red and painful mucosa on denture-bearing surface usually on hard palate and dorsal tongue but may be also find on other parts of oral cavity on hard palate frequently associated with papillary hyperplasia patients may complain of a burning sensation may also be asymptomatic • Allergic or irritant contact stomatitis • Atrophic lichen planus Treatment : !! It is important to remember to treat both : denture (if present) and oral tissues. (The denture will act as a reservoir for the Candida and reinfect the tissues if they are not treated concurrently). ! It is recommended to use topical antifungal agents, directly to the oral lesions or used as a liquid wash. ! Resistant infections or reccurences should be treated with systemic medications. Antifungal drugs are available in various forms : lozenges, pastilles, creams, suspensions. Poliene agents : Nystatin, Amphotericin B Azole agents : Fluconazole, Itraconazole, Ketoconazole !! Ketoconazole can cause changes in liver function 6 ANGULAR CHEILITIS (angular stomatitis, cheilosis, perleche) Etiology : • Candida spp. • Streptococus spp. • Staphylococus aureus Multifactorial condition with a number of local and systemic predisposing factors. Predisposing factors : Clinical presentation : inadequate dentures with reduced vertical deep, red cracks at the corners of the dimension skin creasing with saliva leackage and maceration at corners of the mouth systemic diseas or deficiency (wit.B group) poor oral higiene decrease or increase of saliva flow hypoferric anaemia, megaloblastic anaemia Treatment : mouth,often covered with a pseudo membrane if severe, the splits or cracks may bleed when the mouth is opened and a shallow ulcer or a crust may form burning sensations possible Burning Mouth Syndrome ( stomatodynia in older terminology) o Antimicrobial and antifungal therapy ex. Daktarin 2% gel ( Miconazole ) o Vitamin B BMS occurs most commonly among postmenopausal women ( seven times as often as men), although it affects many other people as well. It is caused by many conditions. o New dentures with correct vertical dimension 7 Causing factors : Diabetes Haematinic deficiences – vitamin B12, iron, folate Salivary glang hypofunction Candidosis Parafunctional habits (chronic trauma) Gastro-oesophageal reflux disease ( GORD) Allergy to restorative or denture materials Depression Some people with burning mouth syndrome don't wake up with mouth pain, but find that the pain intensifies during the day and into the evening. Some awake with a constant daily pain, while others feel pain on and off throughout the day. Clinical presentation : localized burning sensation (tongue,lips,gums,palate) generalized burning sensation normal appearance of oral mucosa ZOSTER( Shingles) Caused by Varicella-Zoster DNA virus morphologically similar to the HSV. Most patients with Zoster are middle-aged or older men. TREATMEMT: very difficult depends on the underlying cause Clinical presentation : • unilateral vesicular eruption in an area of distribution of a sensory nerve • the prodromal pain and tenderness may last for 2-3 days • in mouth vesicles rapidly break Shingles eruptions represent the reactivation of the virus in a previously infected patients. Zoster virus may remain latent in the sensory ganglions for many years. The complications of the condition are very often in geriatric patients: postherpetic neuralgia of trigeminal nerve Paraesthesias down and form ulcers • The trigeminal nerve is involved taste disturbances in about 15% of cases, the optalmic devision is most frequently affected. 8 Treatment : IRON DEFICIENCY ANAEMIA : Causing factors : antiviral drugs ( Acyclovir ) ISOPRINOSINE Vitamin B1, B12, C inadequate intake of iron excessive blood lost ( gastrointerstinal bleeding). Oral symptoms : MEGALOBLASTIC ANAEMIA : • Caused by atrophy of gastric mucosa and consequent • • • • • atrophy of oral mucosa atrophy of tongue epitelium (lost of filiform papillae) = depillated tongue angular cheilitis taste disturbances itching ( glossodynia most frequently) pale oral mucosa Oral symptoms : raw, beefy tongue pale oral mucosa sore mouth and tongue failure of intrinsic factor (IF) necessary for absorption of vitamin B12 Vegans who avoid eating all food of animal origin may also become deficient in vitamin B12 Certain intestinal disorders such as Crohn's disease can also lead to vitamin B12 deficiency. This disease occurs world-wide, but is commonest in Northern Europeans. The peak age of onset is 60 and it is more common in women than in men. ORAL SYMPTOMS IN DIABETES MELLITUS: Diabetes mellitus is a common endocrine disorder that occurs as a result of a deficiency of insulin or resistance to insulin. Two clinical types are recognized: * Juvenile onset – type 1 * Maturity onset –type 2 9 Oral symptoms : VARICES: an abnormal venous dilatation • • • • • • congenital or from demage to vessel wall dry mouth and increase of saliva vicsosity glossodynia- BMS candidosis compromised periodontal health prolonged healing oral mucosa more prone to injury ( trauma, ultraviolet light) occur with increasing frequency over 50 years of age 10
