Painful, ulcerative lesions of various systemic disease can affect the oral mucosa membrane at first. If you don't consider the skin lesion, followed or accompanied by oral mucosa, you are likely to fail in differential diagnosis. In this cases, we introduced erythema multiforme and Stevens-Johnson syndrome(SJS) patients with painful, ulcerative lesions on oral mucosa and skin. Also we review oral mucosal diseases come with the skin lesions.

Oral lichen planus is a premalignant chronic inflammatory mucosal disorder with unknown etiology. It is a multifactorial disease and in addition to genetic background, infections, stress, drug reactions are suggested as risk factors. Helicobacter pylori which is involved in development of many gastrointestinal lesions may also be implicated in oral lichen planus induction. This is of clear importance for cancer prevention and the present study was performed to determine any association between H. pylori infection and oral lichen planus in southwestern Iran. Anti H. pylori IgG levels were determined in 41 patients and 82 sex-age matched controls. The results showed no association between H. pylori infection and oral lichen planus (51% in patients vs. 66% in control). or any of its clinical presentations.

Purpose: Oral lichen planus (OLP) is relatively common mucosal disease in clinical dentistry. OLP is intractable and regarded having malignant potential. Until now, there is some debate on how far OLP can be malignant, and which characteristics can be a risk factor for malignant transformation. Clinician need to know some differences between OLP and lesions similar to OLP to manage properly and suppose prognosis correctly. Therefore, the aim of this study was to divide clinical OLP into two groups and to compare the results of direct immunofluorescence (DIF) between two groups. Methods: This study was conducted on outpatients who visited at the department of Oral Medicine in Chonbuk National University Hospital from January 2007 to November 2015. Patients with DIF result were retrospectively reviewed. The selected patients were classified 'clinical typical of OLP' (CTO) or 'clinical compatible with OLP' (CCW) by modified World Health Organization diagnostic criteria of OLP and oral lichenoid lesion. Results: DIF were classified by deposition intensity or pattern of anti-human antibody and fibrinogen. The classification of fluorescence pattern in each specimen was graded as positive, possibly positive or negative. Conclusions: Both CTO and CCW had positive and possibly positive pattern. Prevalence of positive pattern was 68.8% in CTO and 52.6% in CCW and that of possibly positive pattern was 9.4% in CTO and 5.3% in CCW. Prevalence of negative was 21.8% in CTO and 42.1% in CCW.

Behçet's disease (BD) is a systemic immunological disorder characterized by recurrent mucosal ulcerative lesions including oral and genital ulcerations in association with skin and ocular involvements. BD also can involve the gastrointestinal tract. Gastrointestinal involvement of BD is one of the major causes of morbidity and mortality for this disease. However, clinical data are quite limited because of the rarity of intestinal BD. Therefore, the management of intestinal BD is heavily dependent on expert opinions and standardized medical treatments of intestinal BD are yet to be established. In this brief review, the authors summarized the currently available medical treatments such as 5-aminosalicylic acids, corticosteroids, immuno-modulators, and anti-TNF agents. Moreover, we sought to suggest a treatment algorithm for intestinal BD based on the recently published and updated data.

Toothache is one of the most common discomforts experienced by patients in dental clinic. If clinical and radiographic examinations do not reveal any pathologic findings, we can suspect nonodontogenic toothache. Nonodontogenic toothache can be caused by a variety of causes such as muscle disorders, sinus and nasal mucosal problems, neuropathic pain, neurovascular pain, psychogenic problems, and cardiogenic disease. A thorough history and clinical examination should be performed to confirm the cause of the pain, and more accurate diagnosis can be established through local anesthetic injection. If the nonodontogenic toothache is misdiagnosed, unnecessary dental treatment such as root canal treatment, periodontal treatment, and extraction can be performed, and the patient's pain is not alleviated through such treatment. Therefore, the cause of toothache must be diagnosed correctly before dental treatment is performed, and clinicians should be fully aware of the diseases that may cause these symptoms.

Erythema multiforme (EM) is an inflammatory immune-mediated mucosal disease. EM is classified as EM minor or EM major, depending on the severity of symptoms. Most patients with minor or major forms of EM have oral lesions. EM can occur as a result of adverse drug reactions but this is difficult to establish. Several indicators have been developed that can be used as a criterion of evaluation to ensure objectivity in identifying the causality of adverse drug reactions. The Naranjo algorithm was used in the evaluation to ensure objectivity in identifying the causality of adverse drug reactions. There were two cases of patients suspected of having EM induced by drugs. They were both assessed using the Naranjo algorithm to confirm the causality of the disease.

The biological behavior of mucosal melanoma is aggressive with frequent local recurrence and distant metastasis owing to the abundantly surrounding blood vessels and lymphatics adding to the fact that diagnosis is frequently delayed due to non-specific clinical outcome. The management for mucosal melanoma of the head and neck is controversial in view of the poor prognosis. Ten cases treated over the past 10 years are reported. The average age of the patients was 54.4 years. Seven cases were localized in the nasal cavity and paranasal sinuses and three cases in the oral cavity and nasopharynx. Eight patients had local tumors, one had regional lymph node metastases and one hed lung metastases. Six patients underwent surgical resection, with postoperative radiotherapy in five patients, three patients received radiotherapy and one patient received combination therapy. Recurrence occured in 80% of the patients and the median time to recurrence was 10.5months. The median survival for those who received surgical resection followed by postoperative radiation therapy was 20.8 months and 14.7 months in the radiation therapy only treated group. The author's conclusion is that mucosal melanoma is a highly aggressive disease of the upper respiratory tract in which the best treatment modality is wide surgical resection followed by postoperative radiation therapy.

Careful examination of the oral cavity may reveal findings indicative of an underlying systemic condition, and allow for early diagnosis and treatment. Examination should include evaluation for mucosal changes, periodontal inflammation and bleeding, and general condition of the teeth. A 12-year-old man visited for molar pain during 3 months. He was diagnosed with having a possibility of hematopoietic malignancy, showing the loss of lamina dura, destruction of bony crypt, and high attenuation in the bone marrow. He was referred to department of pediatrics, additional study, including peripheral cell morphology and bone marrow exam, were performed, and diagnosed as acute lymphoblastic anemia. Despite chemotherapy to cure leukemia, he was expired 8 months after initial diagnosis. The purpose of this report is to promote and evoke the awareness regarding an initial examination of the dentist to make an effort to acquire accurate knowledge and information about life-threatening disease in usual dental practice.

Purpose: This study evaluated the predictive role of fecal calprotectin (FC) measured at an early stage of treatment for monitoring clinical remission (CR) after six months and endoscopic remission (ER) after one year of treatment in pediatric Crohn's disease (CD). Methods: This retrospective study included 45 patients who simultaneously underwent ileocolonoscopy and FC testing during follow-up. FC levels were measured before and after six weeks of treatment. CR was assessed after six months of treatment using Pediatric Crohn' s Disease Activity Index and acute-phase reactants. ER was assessed after one year using the Simple Endoscopic Score for Crohn's Disease. Results: Twenty-nine (64.4%) patients used oral prednisolone for remission induction and 16 (35.6%) patients used anti-tumor necrosis factor-alpha. Thirty (66.7%) patients achieved CR, while 24 (53.3%) achieved ER. The FC level measured after six weeks of treatment could predict CR (χ²=9.15, p=0.0025) and ER (χ²=12.31, p=0.0004). The δFC could predict CR (χ²=7.91, p=0.0049), but not ER (χ²=1.85, p=0.1738). With a threshold of ≤950.4 ㎍/g, FC at week six could predict CR with 76.7% sensitivity and 73.3% specificity. The area under the curve (AUC) was 0.769 (standard error 0.0773, p=0.0005). The same threshold predicted ER with 87.5% sensitivity and 71.4% specificity. The AUC was 0.774 (standard error 0.074, p=0.0002). Conclusion: FC assay at an early stage of treatment can be used as a surrogate marker to predict CR and mucosal healing in pediatric CD.

The authors observed the ultrastructure of oral leukoplakia simplex of gingiva, buccal mucosa, tongue and alveolar ridge. For the purpose of clearly defining the lesions under investigation in this study, leukoplakias were cinsidered to be any white patches on the oral mucous membranes that could not be removed by rubbing and could not be classified clinically or microscopically as another diagnosable disease. The tissue to be examined were embedded in paraffin for light microscopic study. The tissue to be examined under the electronomicroscope were fixed in 2.5% glutaraldehyde in 0.1M cacodylate buffer and 1% osmic acid in 0.1M cacodylate buffer, dehydrated with guaded alchol, and treated with propylene oxide, and embedded in Epon.Ultrathin sections were obtained by LKB III ultrotome, stained with uranyl acetate/lead citrate, and examined with Corinth 500EM. The results were as follows : 1. Epithelium of leukoplakia consisted of stratum basale, stratum spinosum, stratum granulosum and stratum corneum. 2. There was hyperorthokerotosis or hyperparakeratosis. 3. Granular cells contained a lot number of membrane coating granule showing lamellar structure, clearing ot codensation, and a lot of keratohyaline granule varied in size. 4. An increased concentration of tonofilaments and an increased number of desmosomes were found in the stratum spinosum. 5. Basal lamina generally showed its continuity, but in some locatoins, its interreption and multiplication appeared.
