ABSTRACT
OBJECTIVE: To evaluate the accuracy of MeMoSA®, a mobile phone application to review images of oral lesions in identifying oral cancers and oral potentially malignant disorders requiring referral. SUBJECTS AND METHODS: A prospective study of 355 participants, including 280 with oral lesions/variants was conducted. Adults aged ≥18 treated at tertiary referral centres were included. Images of the oral cavity were taken using MeMoSA®. The identification of the presence of lesion/variant and referral decision made using MeMoSA® were compared to clinical oral examination, using kappa statistics for intra-rater agreement. Sensitivity, specificity, concordance and F1 score were computed. Images were reviewed by an off-site specialist and inter-rater agreement was evaluated. Images from sequential clinical visits were compared to evaluate observable changes in the lesions. RESULTS: Kappa values comparing MeMoSA® with clinical oral examination in detecting a lesion and referral decision was 0.604 and 0.892, respectively. Sensitivity and specificity for referral decision were 94.0% and 95.5%. Concordance and F1 score were 94.9% and 93.3%, respectively. Inter-rater agreement for a referral decision was 0.825. Progression or regression of lesions were systematically documented using MeMoSA®. CONCLUSION: Referral decisions made through MeMoSA® is highly comparable to clinical examination demonstrating it is a reliable telemedicine tool to facilitate the identification of high-risk lesions for early management.

We present a rare case of ulcerative oral lichen planus that was associated with a thymoma discovered during the management phase, seven months after the initial diagnosis of oral lichen planus. Thymectomy was performed and investigations revealed pure red cell aplasia. Although rare, the association of a thymoma should be considered in recording the medical history of patients presenting with oral lichen planus.
ABSTRACT
Unwanted side-effects of a drug therapy are well known to oral medicine specialists and other colleagues. Usually they manifest itself as dry mouth, taste disturbances, various allergic or toxic reactions on the lips and/or in the oral cavity. However, the list of the drugs which might induce unwanted reactions is everyday becoming longer as more and more drugs are introduced on the market. Certain problems when diagnosing and reporting unwanted side effects of the drugs exist as only accurate method of diagnosis is repeated drug use in controlled clinical setting where fatal consequences due to the anaphilactic shock could be avoided. We report a side effect reaction to tiotropium bromide (Spiriva) cap used with HandiHaler manifesting itself as an oral ulceration in a 65 yrs old male. On the third day of drug intake the patient developed oral ulceration two times in a period of few months. Other medications he has been using for several years. To our knowledge this is a first report as an oral side-effect of this drug used for treatment of chronic obstructive pulmonary disease (COPD).
