The association between smoking and aphthous ulcers.
TL;DR: The results of a preliminary study of the association between smoking and aphthous ulcers indicated potential inhibitory effects of smoking on the occurrence of such oral lesions, and an additional study to validate the suggestion that smoking might be positively associated with decreased aphthou ulceration activity was conducted.

TL;DR: A detailed review of the current knowledge of the etiology, pathogenesis, and managment of RAS is provided.
Abstract: Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal disorders. Nevertheless, while the clinical characteristics of RAS are well-defined, the precise etiology and pathogenesis of RAS remain unclear. The present article provides a detailed review of the current knowledge of the etiology, pathogenesis, and management of RAS.

TL;DR: Different aetiologies and mechanisms might be operative in the aetiopathogenesis of aphthous ulceration, but pain, recurrence, self-limitation of the condition, and destruction of the epithelium seem to be the ultimate outcomes.

TL;DR: Treatment of RAS remains unsatisfactory, as most therapies only reduce the severity of the ulceration and do not stop recurrence, but drugs, especially non-steroidal anti-inflammatory drugs and nicorandil can often control RAS.
Abstract: Recurrent aphthous stomatitis (RAS; aphthae; canker sores) is a common condition which is characterized by multiple recurrent small, round or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or grey floors typically presenting first in childhood or adolescence. RAS occurs worldwide although it appears most common in the developed world. The aetiology of RAS is not entirely clear. Despite many studies trying to identify a causal microorganism, RAS does not appear to be infectious. A genetic predisposition is present, as shown by strong associations with genotypes of IL-1beta; IL-6 in RAS patients, and a positive family history in about one-third of patients with RAS. Haematinic deficiency is found in up to 20% of patients. Cessation of smoking may precipitate or exacerbate RAS in some cases. Ulcers similar to RAS may be seen in human immunodeficiency virus disease and some other immune defects, and drugs, especially non-steroidal anti-inflammatory drugs and nicorandil may produce lesions clinically similar to RAS. Topical corticosteroids can often control RAS. However, the treatment of RAS remains unsatisfactory, as most therapies only reduce the severity of the ulceration and do not stop recurrence.

TL;DR: Diagnosis is on clinical grounds alone, and must be differentiated from other causes of recurrent ulceration, particularly Behçet disease - a systemic disorder in which aphthous-like ulcers are associated with genital ulcers, and eye disease (particularly posterior uveitis).
Abstract: Recurrent aphthous stomatitis (RAS; aphthae; canker sores) is common worldwide. Characterised by multiple, recurrent, small, round, or ovoid ulcers with circumscribed margins, erythematous haloes, and yellow or grey floors, it usually presents first in childhood or adolescence. Its aetiology and pathogenesis is not entirely clear, but there is genetic predisposition, with strong associations with interleukin genotypes, and sometimes a family history. Diagnosis is on clinical grounds alone, and must be differentiated from other causes of recurrent ulceration, particularly Behcet disease - a systemic disorder in which aphthous-like ulcers are associated with genital ulceration, and eye disease (particularly posterior uveitis). Management remains unsatisfactory, as topical corticosteroids and most other treatments only reduce the severity of the ulceration, but do not stop recurrence.

TL;DR: The association of lesions of RAS with hematinic deficiencies and gastrointestinal diseases provides an opportunity to identify a "correctable cause," which, with appropriate treatment, can result in a remission or substantial lessening of disease activity.
Abstract: Recurrent aphthous stomatitis (RAS), commonly known as canker sores, has been reported as recurrent oral ulcers, recurrent aphthous ulcers, or simple or complex aphthosis. RAS is the most common inflammatory ulcerative condition of the oral mucosa in North American patients. One of its variants is the most painful condition of the oral mucosa. Recurrent aphthous stomatitis has been the subject of active investigation along multiple lines of research, including epidemiology, immunology, clinical correlations, and therapy. Clinical evaluation of the patient requires correct diagnosis of RAS and classification of the disease based on morphology (MiAU, MjAU, HU) and severity (simple versus complex). The natural history of individual lesions of RAS is important, because it is the bench mark against which treatment benefits are measured. The lesions of RAS are not caused by a single factor but occur in an environment that is permissive for development of lesions. These factors include trauma, smoking, stress, hormonal state, family history, food hypersensitivity and infectious or immunologic factors. The clinician should consider these elements of a multifactorial process leading to the development of lesions of RAS. To properly diagnose and treat a patient with lesions of RAS, the clinician must identify or exclude associated systemic disorders or "correctable causes." Behcet's disease and complex aphthosis variants, such as ulcus vulvae acutum, mouth and genital ulcers with inflamed cartilage (MAGIC) syndrome, fever, aphthosis, pharyngitis, and adenitis (FAPA) syndrome, and cyclic neutropenia, should be considered. The aphthous-like oral ulcerations of patients with human immunodeficiency virus (HIV) disease represent a challenging differential diagnosis. The association of lesions of RAS with hematinic deficiencies and gastrointestinal diseases provides an opportunity to identify a "correctable cause," which, with appropriate treatment, can result in a remission or substantial lessening of disease activity.

TL;DR: Findings provide support to the view that cancer development in the mouth or pharynx might be enhanced by heavy smoking, heavy drinking or, even possibly, cirrhosis of the liver itself.
Abstract: A New York City cancer study of the mouth and pharynx on 408 cases and 408 age-matched controls revealed that: (1) Cancer of the mouth and pharynx is associated with liver cirrhosis, heavy alcohol consumption and heavy smoking; (2) few Negroes and even fewer Jews had this cancer; (3) multiple or coexisting cancers of the mouth and pharynx are associated with heavy drinking and heavy smoking, especially in the presence of floor of mouth cancer. These findings provide support to the view that cancer development in the mouth or pharynx might be enhanced by heavy smoking, heavy drinking or, even possibly, cirrhosis of the liver itself.
