Burning mouth syndrome Definition and nomenclature A chronic burning sensation in the mouth symptoms als purchase antivert without prescription, typically the tongue (see also Chapter 84) medicine express generic antivert 25 mg without prescription. A monosymptomatic hypochondriasis or an underlying anxiety about cancer or a sexually transmitted infection with perhaps excessive tongue activity appear to be the basis for the complaint of burning mouth syndrome in many patients (Box 110 medicine 4 the people discount antivert 25mg fast delivery. Introduction and general description A chronic burning sensation in the mouth may be due to organic lesions such as geographic tongue or candidosis, or may arise with no evident cause, when it is termed burning mouth syndrome. Clinical features Although the tongue is most frequently involved, the patient may also occasionally complain of burning lips, gums or palate. The burning sensation is usually bilateral and often relieved by eating Epidemiology Incidence and prevalence the overall prevalence is roughly 4%. Several organic lesions, for example haematinic deficiency states, erythema migrans, ulcers, mucositis, lichen planus and candidosis, can cause oral soreness or burning sensation. In contrast, oral discomfort associated with inflammatory lesions is typically aggravated by eating. Laboratory screening for anaemia, diabetes, a deficiency state or candidosis should be undertaken. Management Few patients with burning mouth syndrome have spontaneous remission in the short term, and thus an attempt at treatment is indicated. However, treatment is rarely completely successful, although the condition only infrequently becomes severe. Treatment with placebos, however, may produce a response 72% as large as the response to active drugs [34]. A full blood picture and assays of iron, folate and vitamin B12 are essential in management, as sore tongue can be the initial symptom of a deficiency and can precede any fall in the haemoglobin level. The cause of the deficiency should be sought before replacement treatment is given. Deficiency glossitis may be related particularly to deficiency of iron, folate or vitamin B12, and may then be associated with angular stomatitis and/or mouth ulcers. Occasionally, pernicious anaemia can also produce red areas or patterns of red lines. In many other patients, the tongue can become sore but appear clinically completely See p. Localized hyperpigmented lesions are usually due to pigmentary incontinence, amalgam tattoos, melanotic macule or naevi, Coated, furred, brown or black hairy tongue 110. Generalized oral mucosal hyperpigmentation is usually racial in origin and only occasionally has a systemic cause, such as Addison disease. Amalgam tattoos Amalgam tattoos are common causes of blueblack pigmentation, usually seen in the mandibular gingiva or at least close to the teeth (Figure 110. Similar lesions can result if, for some reason, pencil lead or other similar foreign bodies become embedded in the oral tissues [8,9]. Biopsy may be indicated to exclude a melanoma but otherwise these innocuous lesions require no treatment.

Photoaggravated atopic eczema and nodular prurigo may be distinguished on clinical grounds and insect bites by their shorter time course and asymmetry; phototesting would be normal in these conditions symptoms valley fever cheap 25mg antivert fast delivery. Application of a potent topical steroid to the treated areas immediately after each exposure reduces the risk of disease flares symptoms of strep throat cheap antivert 25mg mastercard. Systemic treatment is more often necessary where the availability of phototherapy is limited and also in countries with more intense yearround sunlight exposure 5 medications for hypertension cheap 25 mg antivert amex. Thalidomide may be more useful, but its use is restricted by teratogenicity and the risk of irreversible peripheral neuropathy. Chronic actinic dermatitis Definition and nomenclature Chronic actinic dermatitis is a chronic dermatitis mainly affecting photoexposed sites, in association with abnormal photosensitivity. The clinical picture and phototesting abnormalities of dermatitis morphology are required for the diagnosis. Associated diseases Chronic actinic dermatitis is associated with contact and/or photocontact allergy in most patients [27]. Epidermal spongiosis, acanthosis and an upper dermal perivascular lymphohistiocytic infiltrate occur acutely (Figure 127. Epidermal hyperplasia, a deep, dermal, inflammatory infiltrate and increased numbers of perivascular histiocytes and granulomatous changes occur chronically [51]. Eosinophils, plasma cells, atypical large, hyperchromatic, convoluted nuclei and mitoses may be evident and Langerhans cells can be increased [37]. In the chronic phase lichenification and pseudolymphomatous (actinic reticuloid) changes can emerge, with epidermotrophism and atypical lymphocytes (Figure 127. If an abnormal eczematous phototest site is biopsied then an acute spongiotic dermatitis will be seen (Figure 127. A role for photoactive drugs has been considered but not substantiated [2,3,7,8,34,35]. The existence of a prolonged prodrome, such as atopic or allergic eczema, before the development of photosensitivity suggests a requirement for persistent Tcell activation to trigger photosensitivity, although does not explain its occurrence in some patients in whom it arises de novo. Light exposure alone appears to suffice as trigger, without an identifiable photoallergen/ allergen(s). Further support for a delayed cell mediated hypersensitivity mechanism was provided by mediator studies. Knowledge of the nature of the antigen/photoantigen(s) is lacking, although photochemical modification of an endogenous protein rendering it antigenic seems plausible [3]. Studies in vitro showed that the photoallergen tetrachlorosalicylanilide was able to photooxidize histidine and modify the carrier protein albumin, rendering this weakly antigenic [43]. Genetics Chronic actinic dermatitis is a sporadic disease and no genetic factors have been identified to date [59]. Environmental factors It is more common in patients with multiple contact allergies [6,27]. Clinical features History the classic features are of a pruritic, recurrent or persistent dermatitis predominantly affecting photoexposed sites and worse in summer (Figure 127.

Radiotherapy has been used for the treatment of numer ous anogenital dermatoses over the years treatment quincke edema buy antivert with a mastercard, including Bowen disease medications zoloft purchase antivert uk, erythroplasia of Queyrat medicine to stop runny nose order antivert 25mg mastercard, squamous carcinoma, psoria sis, Peyronie disease and pruritus ani [8,22]. Radiotherapy con fers a longterm increased risk of skin cancer, especially basal cell carcinoma. There is concern that radiotherapy for Bowen disease or erythroplasia of Queyrat may increase the subsequent risk of invasive carcinoma. Seborrhoeic dermatitis Genital involvement is frequent with this common dermatosis. A good his tory (including family history) and careful examination of other sites typically affected aid the diagnosis. On the scalp, the face, in the flexures and at anogenital sites seborrhoeic dermatitis and psoriasis may be indistinguishable. However, treatments that diminish the Malassezia load and reduce irritation and eczematization can be success fully and safely used long term. These include topical antifungals (such as clioquinol, nystatin and imidazoles) as ointments, creams, lotions or shampoos, and mixtures of the same agents with mild and moderately potent topical corticosteroids used alongside emollients and soap substitutes. Zoon balanitis Introduction and general description An asymptomatic, inflammatory and irritant condition of the glans and mucosal prepuce that is probably overdiagnosed. The evidence suggests that Zoon balanitis is a chronic, reactive, principally irritant dermatosis brought about by a dysfunctional prepuce. There is no evidence of an infectious cause, and immu nohistochemical findings suggest that Zoon balanitis represents a nonspecific polyclonal tissue reaction [9,10], consistent with an irritant dermatosis. Although vegetative and nodular presentations have been recorded, atypical or unusual morphology should be viewed with great suspicion and biopsied [7,8]. Differential diagnosis the differential diagnosis includes lichen sclerosus, erosive lichen planus, psoriasis, seborrhoeic dermatitis, contact dermatitis, fixed drug eruption, secondary syphilis, histoplasmosis [13], erythro plasia of Queyrat [14] and Kaposi sarcoma. A confident clinical diagnosis is not always possible or safe [6,8,15], so a biopsy is advisable, and the pathologist should be asked to look for con comitant disease. In other words, the signs of Zoon balanitis may be sec ondary to underlying preputial disease [8]. Zoon balanitis indicates a dysfunctional foreskin Pathology the classic histology is of epidermal attenuation with absent gran ular and horny layers, and diamond or lozengeshaped basal cell keratinocytes with sparse dyskeratosis and spongiosis. Extravasated erythrocytes, haemosiderin and vascular prolifera tion are also seen. Although Zoon stressed the presence of the plasma cell infiltrate in this condition, the plasma cell numbers can be very variable [7,8,11]. Clinical features the presentation is classically indolent and asymptomatic, although staining of the underclothes with blood has been reported [12]. Most patients diagnosed with Zoons balanoposthitis probably have clinically subtler underlying lichen sclerosus. Case reports concerning the use of topical calcineurin inhibitors have appeared [20,21,22] but these agents should be used with circumspection in the setting of a dysfunctional foreskin and the attendant risk of penis cancer, long term. Again, the pathologist should be asked to examine the whole specimen for signs of another underlying dermatosis. Lichen sclerosus definition and nomenclature Lichen sclerosus is a common inflammatory dermatosis with a predilection for anogenital skin. But the epidemiology and clinical tenor of lichen sclerosus are not those of an infectious or sexually transmit ted disease: it is never seen in sexual partners [9,36]. The presence of the histopathological features of lichen sclerosus in a percentage of acrochordons (skin tags) suggests that occlusion of flaccid skin is a pathogenic factor [37].
