The prognosis for acute and most other forms of chronic candidiasis is excellent.
The underlying defect in most types of mucocutaneous candidiasis, however, militates against cure, although intermittent improve- ment may be noted after the use of systemic antifun- gal agents. The most common form of superficial burn of the oral mucosa is associated with topical applica- tions of chemicals, such as aspirin or caustic agents.
Topical abuse of drugs, accidental placement of phos- phoric acid-etching solutions or gel by a dentist, or overly fastidious use of alcohol-containing mouthrinses may produce similar effects. Clinical Features. In cases of short-term exposure to agents capable of inducing tissue necrosis, a localized mild erythema may occur Figure As the con- centration and contact time of the offending agent increase, surface coagulative necrosis is more likely to occur, resulting in the formation of a white slough, or membrane.
With gentle traction the surface slough peels from the denuded connective tissue, producing pain. Thermal burns are commonly noted on the hard palatal mucosa and are generally associated with hot, sticky foods.
Hot liquids are more likely to burn the tongue or the soft palate. Such lesions are generally erythematous rather than white necrosis , as is seen with chemical burns. Another form of burn that is potentially quite serious is the electrical burn. In particular, children who chew through electrical cords receive rather characteristic initial burns that are often symmetric.
About this article
The result of these accidents is significant tissue damage, often fol- lowed by scarring. The surface of these lesions tends to be characterized by a thickened slough that extends deep into the connective tissue. In cases of chemical and thermal burns in which an obvious clinical slough has developed, the epithelial component shows coagulative necrosis through its entire thickness. A fibrinous exudate is also evident.
The underlying connective tissue is intensely inflamed.
Electrical burns are more destructive, showing deep extension of necrosis, often into muscle. Management of chemical, thermal, or elec- trical burns is quite varied.
For patients with thermal or chemical burns, local symptomatic therapy aimed at keeping the mouth clean, such as sodium bicar- bonate mouth rinses with or without the use of systemic analgesics, is appropriate.
There is a clear structure to each chapter with details of each disease broken down into sections. The differential diagnosis section is useful for linking ideas, emulating the thought processes used by a clinician.
Within each chapter the information is logically and clearly set out to make reading ordered and information memorable. Tables and text boxes are appropriately used to emphasize salient points and it includes high quality photographs and histological images.
Each chapter also provides a comprehensive bibliography for further reading. Aspects of previous editions that have worked well have been kept, such as the valuable clinical overview section at the start of the book.
Key diseases are summarised in a succinct, tabulated form with associated pictures. The disease begins as a pseudomembranous type of candidiasis and is soon followed by nail and cutaneous involvement.
The endocrinopathy usually consists of hypoparathyroidism, Addison's disease, and occasionally hypothyroidism or diabetes mellitus. Other forms of familial mucocutaneous candidiasis have associated defects in iron metabolism and cell- mediated immunity.
A rare triad of chronic mucocutaneous candidia- sis, myositis, and thymoma has been described. The role of the thymus relates to a deficiency in T cell-mediated irnmunologic function, hence provid- ing an opportunity for the proliferation of Candida.
A final form of candidiasis, both acute and chronic, is becoming increasingly evident within the immuno- suppressed population of patients, in particular those infected with HIV. This form of candidiasis was orig- inally described in and is now well recognized as being one of the more important opportunistic infec- tions that afflict this group of patients. The significantly depleted cell-mediated arm of the immune system is believed to be responsible for allowing the develop- ment of severe candidiasis in these patients.
In acute candidiasis, fungal hyphae are seen penetrating the upper layers of the epithelium at acute angles Figure Neutrophilic infiltration of the epithelium with superficial microabscess for- mation is also typically seen. Fungal forms may be enhanced in tissue sections by staining with meth- enamine silver or periodic acid-Schiff PAS reagent.
The predominant fungal forms growing in this par- ticular form of the disease are pseudohyphae. Epithelial hyperplasia is a rather characteristic feature of chronic candidiasis. However, organisms may be sparse, making histologic demonstration sometimes difficult.
Although chronic candidiasis may give rise to oral leukoplakia, there is no clear evidence that chronic candidiasis is in and of itself a precancerous state. The slide is subsequently examined for typical hyphae. Also, culture identification and quantification of organisms may be done on Sabouraud broth, blood agar, or cornmeal agar.
Differential Diagnosis. Candidal white lesions should be differentiated from slough associated with chemical burns, traumatic ulcerations, mucous patches of syphilis, and white keratotic lesions. Red lesions of candidiasis should be differentiated from drug reactions, erosive lichen planus, and discoid lupus erythematosus.
