Objectives: The aim and objectives of this study are to identify oral changes in certain gastrointestinal (GI) diseases, namely gastroesophageal reflux disease (GERD), ulcerative colitis, gastritis, and to evaluate these oral symptoms as indicators for assessing GI disorders., Materials and Methods: In this study, the oral manifestations of various GI disorders were assessed in a varying age group of 250 patients in Government Stanley Medical College and Hospital, Chennai. Out of 250 patients, 142 were affected by GERD, 99 were affected by gastritis, and 9 patients were affected by ulcerative colitis. Of these patients, 177 were males and 73 were females., Results: Evaluation of patients with gastritis revealed that 66.7% affected with gingivitis, 19.2% with dental erosion on the palatal and lingual aspects of maxillary and mandibular teeth predominantly in the anterior region, 10.1% with periodontitis, 2% with gingival erythema. Among the patients with GERD, 44% of the cases showed dental erosion, 25.5% periodontitis, 9.9% gingivitis, 5.7% gingival erythema, 2.8% palatal erythema, 2.1% gingival ulcers, glossitis 2%, 1.4% floor of the mouth erythema, and 0.7% erythema of the tongue. Patients with ulcerative colitis showed 44.4% of gingival erythema, 33.3% of dental erosions, and 22.2% of gingival ulcers and periodontitis., Conclusion: In our study of 250 patients, oral manifestations were observed in 88% of the patients. Both soft tissue and hard tissue changes were evident. There was a high correlation between various GI disease and dental erosion, erythema at various sites of the oral cavity, oral ulcers, gingivitis, periodontitis, and glossitis. Careful evaluation of oral cavity may unveil many GI disorders and help the patient by providing early diagnosis, which further facilitates the prognosis.

Here we reported two patients who presented with panuveitis and were transferred from ophthalmologists to rheumatologists, for both the patients had oral and genital ulcers. They were misdiagnosed with Behcet's disease at first glance. Two young males presented with acute uveitis with history of recurrent oral and genital ulcers. They initially presented with symptoms and signs resembling Behcet's disease and were treated with systemic steroids with suboptimal responses. Routine laboratory test revealed syphilis and human immunodeficiency virus (HIV) infection. After treatment of penicillin and anti HIV virus therapy, the panuveitis was relived. The other patient was lost in the follow up. Recently epidemiological data indicate that syphilis and HIV infection increase, which can mimic the manifestation of Behcet's disease. Diagnosis of sexual transmitted diseases, such as HIV or syphilis needs to be ruled out in all cases that mimic the clinical feature of Behcet's disease, especially for those who had a history of high risk behaviors. Every patient should have history analysis in detail. Screening of sexual transmitted diseases, such as HIV or syphilis is important especially in those rapid progressive panuveitis. Also, other virus infections, such as cytomegalovirus, epstein-barr virus or Herpes simplex virus can cause mucosa ulcers and uveitis. CD4 T cell count is a very important marker to indicate that the patient has immunodeficiency. Erythema nodosa and pseudofolliculitis are the third common clinical manifestation in Chinese Behcet's disease patients. Rheumatologist should watch out for patients without skin involvement when making the diagnosis of Behcet's disease. Syphilis-associated uveitis usually has a good prognosis. Treatment of antibiotics can get good response, 92% uveitis can be relieved, with 67% improved vision. Acute syphilitic posterior placoid chorioretinitis (ASPPC) is a clinically and angiographically distinct manifestation of ocular syphilis. Systemic glucocorticoid can be used in syphilis induced posterior uveitis, sleritis and optic neuritis, and it can also prevent the Hector's reaction. However, for patients diagnosed with both HIV and syphilis, regular antibiotic can not prevent relapse. So doctors need to follow up them regularly. Patients who present with uveitis, oral and genital ulcers can be easily diagnosed with Behcet's disease. Rheumatologists need to be aware of the reemergence of sexual transmitted disease. High degree of clinical suspicion can allow ophthalmologists and rheumatologists to diagnose and treat the disease early. Correct diagnoses timely can get the good treatment response, and rescue the vision. Treatment with regular antivirus and Penicillin can receive the good response, and moreover glucocorticoid can relieve the inflammation.

Langerhans cell histiocytosis (LCH) is a relatively rare and unique disease characterized by an abnormal proliferation of immature dendritic cells. It is predominantly seen in children with adults showing less than ten times the incidence compared to childhood. The clinical presentation and organ involvement is highly variable. Oral manifestations generally consist of mucosal ulceration associated with lesions of the underlying bone. Lesions limited to the oral mucosa are rare. We present a case of a 45-year-old male who presented with an ulcer on the hard palate showing histopathologic features of LCH. The present case is a reminder of the possibility of occurrence of this unusual entity in the oral cavity. Appropriate use of immunohistochemistry is advocated to avoid diagnostic pitfalls.

Cocaine-induced midline destructive lesions (CIMDL) occur in a small subset of cocaine users, who clinically present with inflammation and necrosis of facial midline structures such as the palate, nasal septum, turbinates, and sinuses. We present a patient with CIMDL occurring concomitantly with ulcers on the cheek and upper trunk. Multiple biopsy specimens from the cutaneous and mucosal lesions consistently showed a dense dermal/submucosal infiltrate of neutrophils and plasma cells, without vasculitis or thrombosis. The ulcers resolved following cessation of cocaine use.

A 3-day-old girl was referred from her pediatrician for oral ulcerations. The patient was otherwise well appearing and afebrile. Her prenatal and antenatal courses were unremarkable, except for a failed routine hearing screen. The patient's examination was notable for several yellowish ulcers on erythematous bases located on her anterior tonsillar pillars. The patient also had a right coloboma and a II/VI systolic ejection murmur. Laboratory analyses revealed a traumatic lumbar puncture with 182 000 red blood cells and 808 white blood cells, as well as a complete blood count that showed thrombocytopenia and leukocytosis. During the patient's hospitalization, she developed a new facial rash. Her physical examination findings, along with her diagnostic evaluation and hospital course, ultimately led to 2 surprising diagnoses elaborated on in this case discussion., (Copyright © 2016 by the American Academy of Pediatrics.)

Pemphigus vulgaris (PV) is an autoimmune disease in which the autoantibody, immunoglobulin G, is directed against the keratinocytes in the epidermis. The classic presentations of PV are flaccid vesicles or bullae over the oral mucosa, trunk, groin, and extremities. The age of onset is usually between 40 and 60 years, and cases of PV in children or adolescent patients are rare. Here, we present a 17-year-old boy who had painful oral ulcers for 3 months initially and bullae spreading to the whole body in the following days. Paraneoplastic pemphigus was another differential diagnosis due to the atypical appearance of the skin lesion. However, PV was confirmed by hematoxylin and eosin staining and immunofluorescence examination of the skin biopsy specimens. The patient had a good response to corticosteroid treatment and the immunosuppressive agent, rituximab., (Copyright © 2013. Published by Elsevier B.V.)

Postsurgical injury by teeth to oral mucosa (reconstructed by a flap) can lead to ulceration and subsequent infection at the reconstructed site. A prompt intervention by fabricating a specially designed prosthesis to deflect the reconstruction flap away from the occluding teeth has been described for the treatment of cheek biting in the present clinical report., (Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry.

The incidence of inflammatory bowel diseases (IBD) - Crohn's disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

Accurate diagnosis of acute oral ulcers can be challenging. Important historic details include the pattern of recurrence, anatomic areas of involvement within the mouth and elsewhere on the mucocutaneous surface, associated medical symptoms or comorbidities, and symptomology. Careful mucocutaneous examination is essential. When necessary, biopsy at an active site without ulceration is generally optimal. Depending on the clinical scenario, supplemental studies that may be useful include cultures; perilesional biopsy for direct immunofluorescence testing; and evaluation for infectious diseases, gluten sensitivity, inflammatory bowel disease, human immunodeficiency virus infection, connective tissue diseases, or hematinic deficiencies. Clinicians should maintain a broad differential diagnosis when evaluating patients with acute oral ulcers., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Objective: The aim of this study is to assess the effect of two types of antioxidants, vitamin E (VE) and Aloe vera (AV), on healing of induced oral lesions after radiation in a murine model by clinical and histological analysis., Methods: The animals were randomly divided into three groups of 12 animals each (400 mg VE, 70 % AV and control) and two time periods (5 and 7 days). They were irradiated with a single dose of 30 Gy, and after 24 h, a lesion was produced on the ventral tongue of each animal. The products were applied daily in their respective group until euthanasia., Results: On clinical analysis, there was a higher frequency of lesions in the animals of the control group at both periods. The area of the lesions was also greater in the control group compared with the groups AV and VE (5 days p = 0.006; 7 days p = 0.002). On microscopic analysis, the degree of inflammation differed between the study groups and experimental periods. At 5 days, the statistical difference was not significant among the groups evaluated, but at 7 days, animals in the control group showed intense inflammation, while those in groups VE and AV exhibited mild to moderate inflammation (p = 0.002)., Conclusion: The results suggest that VE and AV contributed to the decrease in inflammatory response and healing of the lesions induced on the tongue of rats subjected to radiation.

Riga-Fede disease (RFD) was initially described as a benign ulceration of the lingual frenum or tongue of infants, most commonly resulting from repetitive trauma by natal teeth. However, similar clinical manifestations can also be found in children with repetitive tongue-thrusting habits or certain neurological disorders. This report describes an unusual case of RFD in a 6-year-old Chinese boy. The lesion appeared as an ulcer on the anterior ventral surface of the child's tongue, and was caused by a repetitive tongue-thrusting habit. After eliminating the source of repetitive trauma and starting concurrent use of therapeutic drugs for 1 week, the lesion healed completely., (© 2015 British Association of Dermatologists.)

The diagnosis and treatment of mucosal disease with an allergic pathogenesis are challenging. Oral allergy is often a hypersensitivity reaction with variable symptoms and physical exam findings. Clinical diagnosis requires a history of prior allergen exposure, a delay from exposure to clinical findings, and improvement following allergen removal. The past decades have seen great contributions to the field of oral allergy. The aim of this review is to provide an approach to the diagnosis and treatment of oral dermatologic disease with a focus on diseases with an investigated allergic pathogenesis.

A 25-year-old man was admitted to our hospital, with fever, severe ulceration of the oral and pharyngeal mucosa, and pustules on his skin. These pathergy-like lesions had emerged after placement of orthodontic braces and laser therapy for hair removal, respectively. The patient's clinical condition, together with his ethnic background, pointed to the diagnosis of Behçet's disease. Treatment with colchicine and prednisone resulted in rapid improvement of his symptoms. Pathergy reactions in response to placement of dental braces and laser hair removal are a rare first presentation of Behçet's disease., (2016 BMJ Publishing Group Ltd.)

Background: A 71-year-old female presented with a left submandibular space abscess. This was found to be due to large accumulations of calculus on the lingual flanges of her lower denture ulcerating the floor of the mouth. She had not taken the prosthesis out since it was provided as an immediate denture after extractions 54 years previously. At presentation she could not take her denture out as the calculus locked the denture under lingual undercuts. The denture was sectioned in the midline to remove it and the submandibular abscess was drained via a neck incision., Findings: Prior to removal the denture was remarkably stable and she had enjoyed a long period of problem free denture wearing and had had exceptional value from it. There was also surprisingly little mandibular alveolar bone resorption., Conclusion: The case demonstrates what may happen if a lower denture is not taken out for over half a century. The calculus on the lingual flanges provided both stability and retention for the denture, and it appeared to have protected the ridge from resorption. While the calculus may have provided some surprising benefits to her lower denture it ultimately led to a serious infection.

Relapsing polychondritis (RP) is a rare rheumatologic disorder in which recurrent episodes of inflammation result in destruction of cartilage of the ears and nose. The joints, eyes, audio-vestibular system, heart valves, respiratory tract, kidneys, and skin can also be involved. Skin involvement is most frequently linked to concomitant myelodysplastic syndrome and has rarely been associated with systemic lupus erythematosus. A 47-year-old woman presented with violaceous, indurated, tender plaques on the bilateral cartilaginous ears with sparing of the lobes, consistent with RP. Further investigations revealed positive ANA and anti-Smith antibody, oral ulcers, a photo-distributed skin eruption, and biopsy-proven lupus nephritis, leading to a second concomitant diagnosis of systemic lupus erythematosus (SLE). The diagnosis of SLE associated with RP was made and the patient was started on oral prednisone and hydroxychloroquine. This is a rare report of SLE associated with RP. It is unclear whether RP occurring in patients with SLE represents another clinical manifestation of SLE or a coexisting disease. However, a significant ANA titer in a patient with RP strongly suggests the presence of an associated autoimmune disorder. If immunologic abnormalities usually found in SLE are detected in patients with RP, it is important to monitor patients for the development of other manifestations of SLE.

Background: Myeloablative and hematopoietic stem cells transplantation therapy (HSCT) often acts as side-effect to oral mucositis (OM) with no effective treatment. This randomized-controlled trial analyzed the efficacy of palifermin, administered as a dose during HSCT therapy, as primary prophylaxis on pediatric patients with acute lymphoblastic leukemia (ALL)., Methods: In this study forty-six patients (9-15 years) with B-cell acute lymphoblastic leukemia (B-ALL) were analyzed. The patients underwent allogenic HSCT conditioned by myeloablative regimen. Subsequently to randomization, patients in the palifermin group were assigned to receive palifermin, 60 mg/kg, intravenously as a single dose 3 days before and after transplant conditioning regimen cycle. The patients in the Control group received only a placebo treatment. Maximum severity of OM, incidence and duration of ulcerative OM, incidence and duration of severe OM limitations were evaluated., Results: A statistically significant reduction in the incidence of OM up to grade 3 in the palifermin group compared to the control group was discovered. There was also a reduction, confirmed at 60 days, in the degree of severity of mucositis in the palifermin group, with an average of 1.54 grade in the palifermin group, and of 2.16 in the Control group and in the use of opioid analgesics., Conclusions: This study indicates that a single dose of palifermin used as primary prophylaxis during HSTC therapy can prevent severe OM in pediatric patients with ALL and used as secondary prophylaxis can prevent the recurrence of severe OM in high-risk patients with previous mucosal injury and improves the quality of life in pediatric patients with ALL.

Mouth ulcers are a common complaint by patients, with individuals regularly presenting to primary care practitioners for diagnosis and treatment. The aetiology and pathogenesis of oral ulceration is, however, both varied and complex. This article highlights the importance of differentiating recurrent aphthous stomatitis (RAS) in otherwise healthy individuals from recurrent oral ulceration (ROU) secondary to known or unknown systemic disease. An overview of the diagnosis and management of such patients is provided as a framework to guide general dental practitioners' with clinical decision making on whether to treat or refer to secondary care.

Urbach-Wiethe disease (lipoid proteinosis) is an autosomal recessive disorder that is characterized by a general thickening of the skin and mucous membranes. We report the case of a 22-year-old woman with lipoid proteinosis who presented with hoarseness, poor dentition, and skin lesions, and we discuss the management of this rare disease.

We report a new clinical manifestation of neonatal Behcet's disease. A newborn from a mother with active Behcet's disease during pregnancy, who develops vasomotor phenomena (Raynaud) with oral ulcerations in the second day of life. Neonatal mucocutaneous lesions have been reported previously in few newborns of pregnant women with active Behçet disease. Although neonatal disease is a very infrequent situation, with a mostly transient and favorable course, clinicians should be aware of serious potential complications associated with this entity.

Our goal was to determine, retrospectively, the occurrence of the symptoms of Behçet's disease in chronological order and the course of the disease. Additionally, probable factors affecting the clinical severity were investigated. A total of 368 patients (171 females and 197 males; aged 41.11 ± 10.9 years) were included in this retrospective cohort study. The chronological order of the clinical manifestations was recorded. Patients were also assessed for clinical severity score. Oral ulcer was the most common manifestation (100 %) followed by genital ulcer (89.4 %), papulopustular lesions (75 %) and articular involvement (60.1 %). Oral ulcer was the most common onset manifestation (66.8 %) followed by genital ulcer (4.9 %), erythema nodosum (3.3 %) and ocular involvement (1.4 %). The duration between the onset symptom and the fulfillment of the diagnostic criteria was 4.67 ± 5.9 years. The duration between the time point of fulfillment of diagnostic criteria and the diagnosis (2.5 ± 2.1 years) was longer in patients having only mucocutaneous lesions (2.8 ± 2.2 years) than in patients having serious organ involvements (1.9 ± 1.6 years; p < 0.01). Serious involvements such as neurological involvement and large vessel involvement had their onsets later. Mean clinical severity score was higher in male patients (5.3 ± 2.1 vs 4.8 ± 1.7; p < 0.05). In logistic regression analysis, male gender (p = 0.03) and increased number of symptoms at diagnosis (p < 0.001, R (2) = 0.73) were found to be significant risk factors for severity. Mucocutaneous lesions, especially oral and/or genital ulcers, usually precede possible serious involvements; therefore, careful follow-up is mandatory. Males with increased number of organ involvements at the diagnosis are associated with more severe disease.

Introduction: Behçet's disease is most prevalent in countries along the former Silk Road. Prevalence varies from 70-420 per 100,000 in Turkey, and 13.5-20 and 1-2 per 100,000 in Asia and Western Europe, respectively. Additionally, disease severity and morbidity might be correlated with ethnicity. We studied demography and morbidity in the Dutch cohort of patients with Behçet's disease and compared those with known figures., Patients and Methods: The prevalence of Behçet's patients in the Rotterdam area was determined by comparing the total number of patients within the ethnic population with the number of patients diagnosed with Behçet's disease. Patient files of the Erasmus University Medical Centre (Erasmus MC) were reviewed for morbidity figures and compared with existing data., Results: In total 84 Behçet's patients of Dutch, Turkish or Moroccan descent were identified in the Rotterdam area. Prevalence of Behçet's disease differed per ethnicity: 1, 71 and 39 per 100,000 for Dutch-Caucasians, Turks, and Moroccans, respectively. These figures are comparable with occurrence in West Turkey and Morocco. Within the studied Erasmus MC cohort no significant differences in morbidity appeared between the ethnic groups. However, uveitis and pustules were significantly more common in the Erasmus MC cohort as compared with UK, German, Turkish and Moroccan cohorts., Discussion and Conclusions: We present the first epidemiological study of Behçet's disease in the Netherlands. The prevalence of Behçet's disease in the studied Dutch region and in countries of ancestry is similar. Morbidity is equally spread, compared with other countries, but uveitis and pustules seem to be more common in the Netherlands.

An unusual lesion that posed a diagnostic challenge was found on the lingual surface of the right mandible of a 52-year-old man. It was asymptomatic, and the patient was unaware of its presence. When information from various sources was pieced together, the lesion was ultimately diagnosed as an oral ulceration with sequestration. This condition is rare and has been reported only sporadically in the literature. The presented case is even less common, because the patient performed a corrective procedure on himself.

Background: Behçet's disease (BD) is a chronic, multisystem, inflammatory pan-vasculitis of unknown etiology, with heterogeneous presentations in different parts of the world. It commonly involves the mucosae, skin, joints, eyes, and central nervous system. Behçet's disease is considered to represent an autoimmune reaction triggered by a yet to be identified infectious agent in a genetically predisposed person. It most commonly affects persons of Mediterranean or Far Eastern origin and is considered rare among Black Africans., Objectives: This study was conducted to document clinical presentations of BD in Nigerians., Methods: A prospective study of the clinical and laboratory parameters of patients who attended dermatology and rheumatology clinics between 2007 and 2011 was carried out., Results: Fifteen patients (nine males, six females) were diagnosed with BD at a mean age of 33 years. The mean age of onset of disease was 27 years. Oral ulceration was present in 100% of subjects and was the most frequent onset lesion, followed by genital ulceration in 93%. Skin, joint, vascular, gastrointestinal, and central nervous system (CNS) lesions occurred in 87, 80, 33, 20, and 13% of patients, respectively. Pathergy tests were positive in 38% of patients. Psychomorbidity was present in 60%. Remission was achieved with corticosteroids, nonsteroidal anti-inflammatory drugs, and disease-modifying anti-rheumatic drugs. Mortality was zero, but 27% of patients were disabled by blindness and 7% by CNS involvement., Conclusions: This is the first report on BD in a sample of Nigerians. The clinical phenotype of BD follows the Middle Eastern pattern. The small number of patients may reflect the rarity of BD in Nigerians or the poor ascertainment of BD by relevant clinicians., (© 2014 The International Society of Dermatology.)

Aim: The aim of this study was to evaluate the oral health status in patients with vascular dementia (VaD). Moreover, the association of the disease severity and the patients' cognitive and functional impairment with the oral findings have been recorded., Methods: The study was directed on the study group (86 VaD patients) and the control group (82 healthy volunteers of the same age) from the IRCSS Neurolesi Bonino-Pulejo in Messina, Italy. Cognitive status was evaluated with the MMSE scoring system. Oral parameters, such as decaying, missing, filled teeth (DMFT) index, plaque index (PI), periodontal probing depth (PPD) and bleeding on probing (BOP) were evaluated in all patients. Denture condition and denture-induced stomatitis were also analysed. The frequency of untreated caries, periodontal diseases and missing teeth of the Study Group was significantly higher than in Control Group., Results: Particularly, VaD patients presented higher number of decayed teeth and deeper periodontal pockets. Decreased cognitive functions in VaD patients have been demonstrated to result in a decline of denture care and increased denture-related mucosal lesions., Conclusion: These results underlined that clinicians should direct high attention to oral hygiene of patients with VaD in order to prevent the evolution of those pathologic dental and periodontal conditions, especially in patients with decreased cognitive functions.

Background: The purpose of this clinical study was to assess the prevalence of acidic oral mucosal lesions and periodontal conditions in patients suffering from erosive esophageal reflux disease (ERD) compared with non erosive esophageal reflux disease (NERD) patients, both treated with long term proton pump inhibitors (PPI)., Methods: Seventy-one patients with diagnosed GERD were studied: i.e. 29 ERD and 42 NERD patients. Thorough visual examination of the oral mucosa and a periodontal evaluation was performed. The primary outcome was defined as a statistically significant difference, between the two groups, in the presence of acidic lesions of the oral mucosa and specific periodontal parameters., Results: This study failed to demonstrate statistically significant differences between ERD and NERD patients with respect to the prevalence of oral mucosal lesions. However, significantly more ERD patients suffered from severe periodontitis (CAL ≥ 5 mm) as compared to NERD patients. Accordingly, it may be assumed that PPI-use had no adverse effects on the prevalence of acidic oral mucosal lesions and on periodontal destruction., Conclusions: Within the limitations of this study it may be concluded that ERD and NERD patients need separate evaluation with respect to periodontal destruction. Moreover, long term PPI medication had no adverse clinical impact on acidic oral mucosal lesions and periodontal destruction. Further studies are necessary to elucidate the role of reflux in the periodontal destruction of ERD individuals.

Oral ulceration is a common finding yet its classification, diagnosis and management remain a challenge for many hospital physicians. This article discusses the different types of oral ulceration and how to investigate and manage them.

We investigated the effect of antibiotic prophylaxis on postoperative inflammatory complications after operations for impacted mandibular third molars in Chinese patients. A total of 207 patients had their bilateral third molars removed in a split-mouth, double-blind, self-controlled, clinical trial in two visits. For one side amoxicillin (or clindamycin) was given (antibiotic group) from one hour before operation until 3 days postoperatively. For the other side a placebo was given (placebo group) at the same time. The outcome, including alveolar osteitis, surgical wound infection, prebuccal infection, and infection of the anterior isthmus of fauces, was assessed 2 and 10 days postoperatively. A total of 192 patients completed the study, and there was no difference between the groups in the incidence of inflammatory complications. In the treatment group, there were 4 cases of alveolar osteitis (2%), 2 infections of the wound (1%), and 14 other reactions (gastrointestinal (n=4), bleeding (n=2), ulcer (n=2), and fever (n=6)). In the placebo group, there were 6 cases of alveolar osteitis (3%), 2 wound infections (1%), and 22 other reactions (bleeding (n=6), ulcer (n=2) and fever (n=14)). There was no significant difference in the extraction time and postoperative reactions, except the pain score on day 10 (p=0.005). Prophylactic amoxicillin (or clindamycin) is not effective for the prevention or reduction of postoperative inflammatory complications after the removal of impacted mandibular third molars in Chinese patients., (Copyright © 2015.

Paraneoplastic pemphigus (PNP) is an autoimmune blistering disorder that occurs in association with an underlying neoplasm. Inflammatory myofibroblastic tumour (IMT) is a rare low-grade sarcoma of fibroblasts and myofibroblasts associated with inflammatory cells, most commonly occurring in the lung. In this study, a case of PNP associated with IMT of the mediastinum is reported. The patient had a favourable outcome following surgical resection and treatment with a systemic steroid, azathioprine, and i.v. immunoglobulin. The occurrence of PNP with sarcomas, specifically IMT, is noteworthy although it is not well studied in the existing literature., (© 2014 The Australasian College of Dermatologists.)

Background: Oral ulcers, the hallmark of Behçet's syndrome, can be resistant to conventional treatment; therefore, alternative agents are needed. Apremilast is an oral phosphodiesterase-4 inhibitor that modulates several inflammatory pathways., Methods: We conducted a phase 2, multicenter, placebo-controlled study in which 111 patients with Behçet's syndrome who had two or more oral ulcers were randomly assigned to receive 30 mg of apremilast twice daily or placebo for 12 weeks. This regimen was followed by a 12-week extension phase in which the placebo group was switched to apremilast and a 28-day post-treatment observational follow-up phase. The patients and clinicians were unaware of the study assignments throughout the trial. The primary end point was the number of oral ulcers at week 12. Secondary outcomes included pain from these ulcers (measured on a 100-mm visual-analogue scale, with higher scores indicating worse pain), the number of genital ulcers, overall disease activity, and quality of life., Results: The mean (±SD) number of oral ulcers per patient at week 12 was significantly lower in the apremilast group than in the placebo group (0.5±1.0 vs. 2.1±2.6) (P<0.001). The mean decline in pain from oral ulcers from baseline to week 12 was greater with apremilast than with placebo (-44.7±24.3 mm vs. -16.0±32.5 mm) (P<0.001). Nausea, vomiting, and diarrhea were more common in the apremilast group (with 22, 9, and 12 incidents, respectively, among 55 patients) than in the placebo group (with 10, 1, and 2 incidents, respectively, among 56 patients), findings that were similar to those in previous studies of apremilast. There were two serious adverse events in patients receiving apremilast., Conclusions: Apremilast was effective in treating oral ulcers, which are the cardinal manifestation of Behçet's syndrome. This preliminary study was neither large enough nor long enough to assess long-term efficacy, the effect on other manifestations of Behçet's syndrome, or the risk of uncommon serious adverse events.

Background: Pediatric discoid lupus erythematosus (DLE) is rare. The risk of progression to systemic lupus erythematosus (SLE) is uncertain., Objective: We sought to determine the risk of progression of pediatric DLE to SLE and to characterize its phenotype., Methods: This was a retrospective review of 40 patients with DLE., Results: Six (15%) of 40 patients presented with DLE as a manifestation of concurrent SLE. Of the remaining 34, 9 (26%) eventually met SLE criteria and 15 (44%) developed laboratory abnormalities without meeting SLE criteria. Only 10 (29%) maintained skin-limited disease. The average age at progression to SLE was 11 years, with greatest risk in the first year after DLE diagnosis. Most (89%) patients with SLE met diagnostic criteria with mucocutaneous disease (discoid lesions, malar rash, oral and nasal ulcers, photosensitivity), positive antibodies, and/or cytopenia without developing end-organ damage over 5 years of median follow-up., Limitations: The study was retrospective., Conclusions: In pediatric patients, DLE carries a significant risk of progression to SLE but may predict a milder phenotype of systemic disease. All patients require careful monitoring for SLE, particularly within the first year of diagnosis., (Copyright © 2014 American Academy of Dermatology, Inc. Published by Elsevier Inc.
