Abstract
Dermatomyositis is a chronic systemic autoimmune disease characterized by inflammatory infiltrates in the skin and muscle. The wide variability in clinical and serologic presentation poses a diagnostic challenge for the internist. Appreciation of the clinical variants of dermatomyositis allows for expedient diagnosis and avoidance of diagnostic error. We illustrate these challenges with the case of a 51-year-old Vietnamese-American man who initially presented with fever of unknown origin in the absence of overt skin and muscle manifestations. The diagnosis of dermatomyositis was not evident on several clinical encounters due to the absence of these hallmark symptoms. We review the variable clinical manifestations of a subtype of dermatomyositis associated with an autoantibody against melanoma differentiation-associated protein 5 (anti-MDA5) and suggest consideration of dermatomyositis as a diagnosis in patients presenting with systemic illness and markedly elevated ferritin, even in the absence of elevated muscle enzymes and classic autoantibodies.

Abstract
Dermatomyositis is an autoimmune inflammatory myopathy associated with dermatologic findings. Its association with neoplasms is widely reported and has been shown to be higher in lung cancer, particularly small-cell carcinoma, probably as it originates from neuroendocrine cell precursors, as well as breast and ovarian cancer. The low frequency of dermatomyositis makes it difficult to suspect the underlying lesions among the diagnostic possibilities of systemic diseases with cutaneous manifestations. Therefore, the high probability of a neoplasm should always be considered, with reports of up to 75% in the eastern population and about 40% in general. In this report, we present a rare case of dermatomyositis with lesions in a shawl-like distribution, as a symptomatic debut of a small cell lung carcinoma.

Abstract
A 76-year-old woman with muscle ache, weakness of the extremities, and skin rash was diagnosed with dermatomyositis (DM). Upon the diagnosis of DM, a systemic survey of malignancy revealed an advanced carcinoma of the ascending colon. The patient underwent right hemicolectomy approximately 2 months after the onset of DM. The symptoms and signs of DM disappeared after the surgery without additional therapy. DM is an idiopathic systemic inflammatory disease characterized by muscle ache, muscle weakness, and skin rash. In some cases, DM develops as paraneoplastic syndrome, and it is assumed that 30% of DM patients have cancer. Symptoms and signs of DM can be attenuated by treatment of the malignancy, and they reappear if the malignancy recurs. It is essential to perform a systemic survey of malignancy in DM patients, and treatment of the malignancy has to precede treatment of DM.

Abstract
This study aims to investigate the prevalence and predictive risk factors of malignancy in patients with polymyositis (PM) and dermatomyositis (DM). The medical records of 192 PM/DM patients followed up in a medical center between January 2000 and December 2013 were reviewed. Among the 192 patients, 33 patients (17.2 %) had associated cancer. Both PM and DM are significantly associated with cancer, although the risk of cancer appears to be somewhat higher among patients with DM (23.0 %) than among those with PM (8.9 %). Nasopharyngeal cancer (30.3 %) and breast cancer (18.2 %) comprised the most common malignant diseases associated with PM/DM. Univariate analysis showed that an older age at PM/DM onset, heliotrope rash, Gottron's sign, dysphagia, and low creatine phosphokinase (CPK) level were associated with increased malignancy. Multivariate analysis revealed that independent predictors of malignancy in PM/DM were age >40 years at PM/DM onset (adjusted OR 3.44; 95 % CI 1.08-10.98; p = 0.037) and heliotrope rash (adjusted OR 2.96; 95 % CI 1.04-8.43; p = 0.042). During the follow-up period, 66 (34.4 %) patients died and the overall patient survival rates were 83.1 % at 1 year, 78.9 % at 2 years, 74.2 % at 5 years, and 65.5 % at 10 years. This study demonstrates a high frequency of malignancy (17.2 %) in DM/PM patients. Nasopharyngeal cancer and breast cancer were the most common cancer types in DM/PM patients in our study. Cancer screening should be offered to patients with newly diagnosed DM/PM. Moreover, all patients should be evaluated for the possibility of an underlying malignancy during treatment.

Abstract
Objective Dysphagia develops with low frequency in patients with dermatomyositis. Our objective was to determine the clinical and laboratory features that can estimate the development of dysphagia in dermatomyositis. Methods This study included 92 Japanese patients with adult-onset dermatomyositis. The associations between dysphagia and clinical and laboratory features including disease-specific autoantibodies determined by immunoprecipitation assays were analyzed. Results Videofluoroscopy swallow study (VFSS) was performed for all patients with clinical dysphagia (n = 13, 14.1%) but not for patients without clinical dysphagia. Typical findings of dysphagia (pharyngeal pooling, n = 11 and/or nasal regurgitation, n = 4) was detected by VFSS in all patients with clinical dysphagia. Eleven patients with dysphagia (84.6%) had anti-transcription intermediary factor 1γ (TIF-1γ) antibody. By univariate analysis, the average age and the male to female ratio, internal malignancy, and anti-TIF-1γ antibody were significantly higher and the frequency of interstitial lung diseases and manual muscle testing (MMT) scores of sternomastoid and dertoid muscles were significantly lower in patients with dysphagia than in patients without dysphagia. Among patients with anti-TIF-1γ antibody, the mean age, the ratios of male to female and internal malignancy were significantly higher and mean MMT scores of sternomastoid muscle were significantly lower in patients with dysphagia compared with patients without dysphagia. By multivariable analysis, the risk of dysphagia was strongly associated with the existence of internal malignancy and ant-TIF-1γ antibody and was also associated with reduced scores of manual muscle test of sternomastoid muscle. Dysphagia was markedly improved after the treatment against myositis in all 13 patients. Conclusion These findings indicate that dysphagia can develop frequently in patients with internal malignancy, anti-TIF-1γ antibody, or severe muscle weakness of sternomastoid muscle.

Abstract
The strong association between myositis and malignancy has been well recognised. Cancer-associated myositis (CAM) is thought to be a cross-reaction to regenerating muscle tissue similar to tumour antigen. We report a case of CAM due to oesophageal adenocarcinoma arising in Barrett's oesophagus without elevation of myogenic enzymes, diagnosed by MRI and repeated endoscopy. Elderly onset, prominent symptoms, lack of interstitial pneumonia, poorer response to immunosuppressive therapies, and the combination of negative conventional myositis-related antibodies and positive anti-p155/140 antibody may help to distinguish CAM from idiopathic inflammatory myopathy. As the prognosis of patients with CAM depends on the malignancy, aggressive diagnosis of CAM and the causative malignancy is required. Our experience underscores the importance of avoiding the over-reliance on serum myogenic enzymes for excluding CAM and recognising MRI as a useful diagnostic tool of myositis.

Abstract
Objective An association has been reported between inflammatory myopathies (IMs), which include polymyositis (PM) and dermatomyositis (DM), and malignancy, and the concept of cancer-associated myositis (CAM) was recently proposed. We herein attempted to determine the features and etiologies of these myopathies. Methods We analyzed the gene expression levels via microarray and real-time quantitative reverse transcription polymerase chain reaction analyses to identify genes that were specifically upregulated or downregulated with suspected inflammatory involvement and verified the microarray data via an immunohistochemical (IHC) analysis in additional cases. Patients We selected 14 patients with the following conditions: PM without malignancy (n=3), DM without malignancy (n=3), CAM (n=3), and Controls (no pathological changes or malignancy; n=5). Results PM was distinct from DM and CAM in a clustering analysis and exhibited the highest numbers of overexpressed genes and specific pathologies in a gene ontology analysis. The IHC analysis confirmed the gene expression results. Conclusion PM is associated with severe inflammatory pathological findings, primarily in the cell-mediated immune system. DM and CAM exhibit similarities in the gene expression and IHC results, which suggest that humoral immunity is the main etiology for both myopathies, indicating the importance of cancer screening in patients with IMs, particularly DM.

Abstract
OBJECTIVE To identify clinical and serologic correlates of cutaneous ulcers in dermatomyositis (DM). METHODS We retrospectively examined a cohort of 152 DM patients. We compared the features of patients with ulcers to those without ulcers using chi-square or Fisher's exact tests and used univariate and multivariate logistic regression models to assess the association between ulcers and clinical features such as malignancy, interstitial lung disease (ILD), and amyopathic disease. RESULTS Forty-three patients (28%) had cutaneous ulcers. Nearly half the patients had ulcers present in more than 1 location: 24 (56%) had ulcers over the extensor surfaces of joints, 18 (42%) at the digital pulp or periungual areas, and 25 (58%) had ulcers located elsewhere. In univariate analysis ulcers were associated with Asian race, but not with other clinical and demographic features, including malignancy or ILD. In multivariate analysis ulcers were significantly associated with anti-melanoma differentiation gene 5 (anti-MDA5) antibodies (odds ratio 10.14, 95% confidence interval 1.95-52.78; P = 0.0059) and this was greatest for ulcers located at the digital pulp. In patients with cutaneous ulcers, ILD risk was specifically increased only in patients with anti-MDA5-positive antibodies. CONCLUSION We confirmed the strong association between anti-MDA5 antibodies and cutaneous ulcers, with the novel finding that the association of cutaneous ulcers with ILD depends upon the presence of anti-MDA5 antibodies. DM patients who display this cutaneous phenotype should undergo appropriate evaluation for ILD.

Abstract
BACKGROUND AND AIM Paraneoplastic syndrome is a disease or symptom that is the consequence of cancer in the body but, unlike mass effect, is not due to the local presence of cancer cells. An overlap of two paraneoplastic syndromes secondary to lung cancer in a patient is very rare. In order to improve the diagnosis of two paraneoplastic syndromes secondary to lung cancer, we reported an overlap of two paraneoplastic syndromes secondary to lung squamous carcinoma in a patient. METHODS We reported a case of a 60-year-old male smoker who presented multiple erythematous lesions for 6 months with progressive proximal muscular weakness, and developed to dysphonia in 2 months. His chest computed tomography showed a spiculate pulmonary nodule near the hilar in the right upper lobe and mediastinal lymph nodes enlargement. Lung biopsy showed squamous cell carcinoma. The patient's blood test revealed elevated creatine kinase levels. Electromyography results were consistent with moderate myopathy accompanied with a pattern suggestive of Lambert-Eaton myasthenic syndrome. RESULTS So we made the diagnosis of an overlap of two paraneoplastic syndromes (dermatomyositis and Lambert-Eaton myasthenic syndrome) secondary to lung squamous carcinoma. CONCLUSION Recognition of paraneoplastic syndrome is crucial for early diagnosis of lung cancer because up to 80% of patients may present paraneoplastic syndromes before any other direct indication of malignancy. Early diagnosis and treatment of paraneoplastic syndrome is also important because delayed diagnosis may result in rapid disease progression and irreversible neurological damage.

Abstract
INTRODUCTION Idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by progressive proximal muscle weakness. Cancer-associated myositis represents the worst prognostic group within this heterogeneous disease. AIM The aim of this study was to reveal factors which increase the risk factors for association of cancerous disease in patients with myositis. Furthermore, the authors explored the most common types of associated malignancies in their patients with myositis and characterize the clinical findings in a sub-group of anti-p155/140 positive patients. METHOD In this retrospective study, myositis patients with and without associated cancer were analysed (32 and 64 patients, respectively). In addition, anti-p155/140 positive and negative groups were compared, irrespective to the presence of associated malignancies. RESULTS The risk for associated malignancy was higher in patients with severe muscle and skin symptoms and those with dermatomyositis. Furthermore, increased risk for malignancy was noted in the presence of particular skin symptoms and the absence of systemic symptoms. The anti-p155/140 antibody was proved to be a feasible marker of an independent clinical sub-group which overlapped clinical characteristics with cancer-associated myositis. CONCLUSIONS These results may help the identification of patients with myositis with a higher risk for associated malignancy.

Abstract
BACKGROUND Although some features of dermatomyositis (DM) and polymyositis (PM) have been reported as possible prognostic indicators for cancer development, previous studies were small in size and were unable to establish a definitive relationship between neoplasms and DM and PM. OBJECTIVES To evaluate risk factors for developing malignancies in patients with DM and PM. METHODS Meta-analysis of the studies reported in the literature was performed to unveil risk factors for developing cancer among patients with DM and PM. The included studies were either cohort or retrospective case-control studies with information on cancer status. Risk for malignancy was determined as the odds ratio (OR) or weighted mean difference (WMD) with a 95% confidence interval (CI), determined by fixed and random effects models. Stata 10.0 software was used to identify possible publication bias. RESULTS Twenty studies with 380 patients and 1575 controls were included in the analysis. The factors that may increase the risk of cancer in patients with DM and PM were older age (WMD 11·41, 95% CI 9·84-12·98), male sex (OR 1·92, 95% CI 1·49-2·48), cutaneous necrosis (OR 5·52, 95% CI 3·49-8·74) and dysphagia (OR 2·41, 95% CI 1·50-3·86), whereas those that may provide protection against cancer included arthritis (OR 0·38, 95% CI 0·24-0·61) and interstitial lung disease (OR 0·32, 95% CI 0·20-0·51). CONCLUSIONS Our data suggest that age, sex, cutaneous necrosis, dysphagia, arthritis and lung complications may influence susceptibility to cancer in patients with DM and PM.

Abstract
Objective To define potential factors that could predict concomitant neoplastic diseases in patients diagnosed with PM/DM, which could inform screening decisions. Methods Two researchers independently reviewed articles from Pubmed (MEDLINE), EMBASE, Cochrane Plus Library and ISI Web of Knowledge with no restrictions on study design or language. Given that some of the studies combined PM and DM patients as research subjects while others included only DM patients, data were subjected to meta-analyses for all combined PM/DM studies and studies that included only DM patients to obtain informative results. Results For PM/DM patients, the following factors are all associated with an increased risk of malignancy: older age, age greater than 45, male sex, dysphagia, cutaneous necrosis, cutaneous vasculitis, rapid onset of myostis (<4 weeks), elevated CK, higher ESR, higher CRP levels. Several factors were associated with lower-than-average risk, including the presence of ILD, arthritis/arthralgia, Raynaud's syndrome, or anti-Jo-1 antibody. For DM patients, results indicated an increased risk of malignancy with older age, male sex, the presence of cutaneous necrosis, elevated ESR (>35 mm/hr), higher CRP levels, or anti-p155 antibody. In addition, the presence of anti-ENA antibodies seem to be related to reduced risk of malignancy. Conclusion Awareness and implementation of early-stage cancer screening in PM/DM patients who have these identified factors – such as being older than 45, male sex, cutaneous necrosis, cutaneous vasculitis – are of crucial importance from public health and clinical perspectives and provide insight into the etiopathogenesis of CAM.

Abstract
This study is aimed at retrospectively studying cancer-associated inflammatory myopathies (CAM) in a cohort of patients with inflammatory myopathies. CAM were diagnosed if the tumor was diagnosed 2 years before or after disease onset. One hundred and sixty-two patients were included, 27 (17 %) had CAM. A significant association was observed between CAM and dermatomyositis (DM), older age and dysphagia at disease onset. CAM have lower creatine kinase (CK) levels at onset and a low prevalence of autoantibodies. In conclusion, the association of male sex, older age, DM, dysphagia at onset, lower CK, and autoantibodies negativity carries a high suspicion of CAM.

Abstract
Dermatomyositis is a specific type of inflammatory myopathy with characteristic cutaneous findings. Patients may have skin disease without clinically apparent muscle disease, but this disorder is best thought of as a systemic process. Therefore, all patients with dermatomyositis skin lesions need appropriate evaluation for muscle disease, esophageal dysfunction, cardiopulmonary disease, and potential internal malignancy. There are many therapies that have been used for patients with dermatomyositis, but most are based upon case series or expert opinion rather than meta-analyses or randomized, placebo-controlled trials. Even those therapies that have been subjected to randomized, blinded, placebo-controlled trials include a mixture of patients with idiopathic inflammatory myopathy and do not utilize a validated assessment tool for measuring cutaneous disease responses. In this review, we discuss the therapies available as well as the internal associations with dermatomyositis.

Abstract
OBJECTIVES Although simultaneous occurrences of autoimmune pancreatitis (AIP) and cancer are occasionally observed, it remains largely unknown whether cancer and AIP occur independently or these disorders are interrelated. The aim of this study was to examine the relationship between AIP and cancer. METHODS We conducted a multicenter, retrospective cohort study. One hundred and eight patients who met the Asian diagnostic criteria for AIP were included in the study. We calculated the proportion, standardized incidence ratio (SIR), relative risk, and time course of cancer development in patients with AIP. We also analyzed the clinicopathological characteristics of AIP patients with cancer in comparison with those without cancer. RESULTS Of the 108 AIP patients, 18 cancers were found in 15 patients (13.9%) during the median follow-up period of 3.3 years. The SIR of cancer was 2.7 (95% confidence interval (CI) 1.4-3.9), which was stratified into the first year (6.1 (95% CI 2.3-9.9)) and subsequent years (1.5 (95% CI 0.3-2.8)) after AIP diagnosis. Relative risk of cancer among AIP patients at the time of AIP diagnosis was 4.9 (95% CI 1.7-14.9). In six of eight patients whose cancer lesions could be assessed before corticosteroid therapy for AIP, abundant IgG4-positive plasma cell infiltration was observed in the cancer stroma. These six patients experienced no AIP relapse after successful cancer treatment. CONCLUSIONS Patients with AIP are at high risk of having various cancers. The highest risk for cancer in the first year after AIP diagnosis and absence of AIP relapse after successful treatment of the coexisting cancers suggest that AIP may develop as a paraneoplastic syndrome in some patients.

Abstract
OBJECTIVES The objective of this study was to assess the incidence and common types of concomitant malignancies and to define predictive factors of death in Korean patients with idiopathic inflammatory myopathy (IIM). METHODS From January 1989 to May 2011, 162 patients were diagnosed with IIM at a university hospital in Korea. The medical records were retrospectively reviewed. The clinical findings of the patients were compared for malignancy, and the prognostic factors predicting death were analyzed. RESULTS Malignancies were found in 17 patients (10.5 %), all of whom had a significantly lower frequency of interstitial lung disease (ILD) and an older age at onset. The main causes of death were ILD and malignancy. Older age at diagnosis, presence of malignancy, rapidly progressive ILD and minimal creatinine phosphokinase (CPK) elevation were independent risk factors for death. CONCLUSIONS Malignancy was one of the most serious risk factor for death in our patients with IIM. Early discovery of malignancy is important, and an extensive investigation for common malignancies in each region should be done at diagnosis and for a minimum of 2 years thereafter. As minimally elevated CPK levels in ILD patients may be associated with fatal ILD, an early evaluation and a more aggressive treatment of ILD should be considered in these patients.

Abstract
In patients with myositis, the lung is commonly involved, and the presence of anti-aminoacyl-tRNA synthetase (anti-ARS) antibodies marks the presence or predicts the development of interstitial lung disease (ILD). A distinct clinical entity-antisynthetase syndrome-is characterized by the presence of anti-ARS antibodies, myositis, ILD, fever, arthritis, Raynaud's phenomenon, and mechanic's hands. The most common anti-ARS antibody is anti-Jo-1. More recently described anti-ARS antibodies might confer a phenotype that is distinct from that of anti-Jo-1-positive patients and is characterized by a lower incidence of myositis and a higher incidence of ILD. Among patients with antisynthetase syndrome-related ILD, the response to immunosuppressive medications is generally, but not universally, favorable.

Abstract
There are several key observations on paraneoplastic myopathies: The risk of cancer associated with DM is very high, whereas risk of cancer associated with PM is mildly increased Most cancers develop within one year of the onset of myositis, although the risk remains high up to 5 years after diagnosis. The most common cancers associated with DM are adenocarcinoma, including lung, ovary, cervical, stomach, pancreas, colorectal and lymphoma, whereas PM is associated with a high risk of lymphoma. The clinical course of myopathy is closely linked with the course of cancer. Certain clinical features are associated with CAM including severe treatment resistant skin manifestations, severe muscle weakness, respiratory muscle weakness, and dysphagia, while some clinical features are protective such as arthritis, Raynaud, and ILD. Screening should be based on age, gender, ethnicity, and the geographic area of the patient; however, certain high-risk patients may require more extensive screening including tumor markers and thoracoabdominal–pelvic CT scans. Certain autoantibodies including anti-p155 and the absence of more common autoantibodies are associated with a higher risk of CAM, while the presence of antisynthetase autoantibodies lowers the risk for CAM. Although the pathogenesis of CAM is unclear, a plausible hypothesis is that immune responses generated against antigens commonly targeted in myositis are related to antitumor responses in affected individuals.

Abstract
Dermatomyositis is associated with an underlying malignancy in about 24% of cases. This association is also true for polymyositis but is less prominent. The malignancy is usually an adenocarcinoma of the ovary, lung, or gastrointestinal tract in Western countries and nasopharyngeal carcinoma in Southeast Asia, Southern China, and Northern Africa. Factors predictive of malignancy in myositis patients include more severe skin and muscle disease and the absence of overlap connective tissue disease features, such as interstitial lung disease. Anti-p155/140 antibodies have a strong predictive value for malignancy in adult patients. Patients with dermatomyositis or polymyositis require an evaluation for occult malignancy at the time of diagnosis and, in some cases, in the event of a subsequent recurrence. This paraneoplastic phenomenon may stem from an immune reaction to antigens expressed in both cancer cells and regenerating fibers in affected muscle.

Abstract
OBJECTIVE To define the standardized incidence ratio (SIR) of malignancy and factors associated with malignancies in Korean patients with dermatomyositis (DM) and polymyositis (PM). METHODS The demographic, clinical, and laboratory features of 151 patients diagnosed with DM/PM were compared in patients with and without malignancies. RESULTS Malignancies were found in 23 of 98 patients with DM (23.5%) and in 2 of 53 with PM (3.8%). Lung cancer (8 patients) was the most common malignancy. Compared with the period-specific, sex-matched, and age-matched Korean population, the SIR for malignancy in patients with DM was 14.2 (95% CI 9.0-21.3). Univariate analysis showed that factors associated with malignancy included older age (p < 0.001), DM (p = 0.002), dysphagia (p < 0.001), the absence of interstitial lung disease (ILD; p = 0.001), and lower elevations in aspartate aminotransferase (p = 0.005) and lactate dehydrogenase concentrations (p < 0.001). Multivariate analysis showed that factors independently associated with malignancy included older age (per 10 years, OR 2.3, 95% CI 1.6-3.5, p < 0.001), DM (OR 5.9, 95% CI 1.3-26.2, p = 0.020), dysphagia (OR 2.6, 95% CI 1.2-6.6, p = 0.042), and the absence of ILD (OR 0.1, 95% CI 0.01-0.9, p = 0.040). CONCLUSION DM was associated with a greater risk of concomitant malignancies, especially lung cancer, than PM. Independent factors associated with malignancies in patients with DM/PM were older age, the presence of dysphagia, and the absence of ILD.

Abstract
In paraneoplastic muscle disease, the malignancy may remotely affect neuromuscular transmission or incite muscle inflammation or necrosis. In several of these diseases, an autoimmune basis for the muscle disease has been established and has become a defining feature. These paraneoplastic muscle diseases may be the first manifestation of a malignancy, and their diagnosis thus demands a vigilant search for an underlying tumor. This article is focused on inflammatory and necrotizing myopathies and disorders of neuromuscular transmission that may arise in the setting of malignancy and are considered paraneoplastic phenomena.

Abstract
Objectives: To study the electroclinical and histopathologic profile of idiopathic inflammatory myositis (IIM) with reference to prognosis and survival rate. Materials and Methods: Diagnosis of IIM was based on the Bohan and Peter criteria. Patients who improved and those whose condition worsened or who expired due to IIM per se at last follow-up were classified to have favorable and poor outcomes, respectively. Fisher’s exact test was used for univariate analysis of prognostic factors. Results: The study cohort consisted of consecutive 68 patients with IIM. The mean age at diagnosis was 36.5 years and females constituted 71%. Of these patients, 62% had definite IIM, 49% had polymyositis, 20% had dermatomyositis, and 29% had overlap syndrome. The mean follow-up period was 5.4 years. Prednisolone alone was used in 55 (80%), and azathioprine (1–3 mg/kg/day) alone in 12 (17.6%) as the initial treatment. Relapse of IIM with drug withdrawal was seen in 15 patients (22%); 70% had favorable outcome and 16% had expired. The treatment delay of ≤6 months (P = 0.001), absence of cardiac or lung involvement (P < 0.001), and positive biopsy (P = 0.033) were predictive of a favorable prognosis in the univariate analysis. In multivariate analysis, only the duration of illness of ≤6 months (P = 0.008) and the absence of cardiac or lung involvement (P = 0.001) predicted the favorable outcome at last follow-up. Cumulative survival rate was 95% at 1 year, 86% at the 5th year, and 80% at the 10th year. Conclusions: Approximately, two-thirds of the patients showed good electroclinical and histopathologic correlations and an equal number improved with treatment. The treatment delay (≥6 months), presence of cardiac or pulmonary involvements, and negative muscle biopsy are bad prognostic factors.

Abstract
BACKGROUND AND OBJECTIVE Reports on the coexistence of dermatomyositis (DM) with autoimmune thyroiditis (AIT) are very few. Our aim is to define the relationship of the two conditions, identify clinical, laboratory, electromyographic and pathologic features of coexistent DM and AIT. METHODS We underwent a MEDLINE search to identify relevant literature published in the past 30 years. Concurrently, we analysed retrospectively medical records of five patients diagnosed with DM and AIT from our hospital. RESULTS Eleven cases were included. 90.9% of patients were female with a mean (SD) age of 44.18 (13.11) years for DM at diagnosis, and 39.00 (7.81) years for AIT. AIT can precede or parallel the diagnosis of DM. The most common comorbidities included hypothyroidism (90.9%), cardiopulmonary diseases (63.7%) and overlap syndrome (27.3%), while only one case had malignancy. The most common clinical manifestations were: muscle weakness (100%), polyarthralgia (45.5%), heliotrope rash (45.5%), myalgia (36.4%), and Raynaud's phenomenon (27.3%). The abnormalities on electromyography and muscle/skin biopsy of DM related to AIT did not differ from those findings of DM, while none of these reports were normal. All patients received both the treatment of corticosteroids and levothyroxine, and only 27.3% of patients had a good prognosis. CONCLUSION Prevalence of cancer in coexistent DM and AIT may be very low. Also, it is reasonable to suggest that DM patients with AIT should be routinely evaluated for thyroid function and the emergence of comorbidities. Moreover, corticosteroids combined with levothyroxine may be useful for these patients as a standard treatment.

Abstract
BACKGROUND Dermatomyositis (DM) and polymyositis (PM) are rare systemic autoimmune rheumatic diseases with high fatality rates. There have been few population-based mortality studies of dermatomyositis and polymyositis in the world, and none have been conducted in Brazil. The objective of the present study was to employ multiple-cause-of-death methodology in the analysis of trends in mortality related to dermatomyositis and polymyositis in the state of São Paulo, Brazil, between 1985 and 2007. METHODS We analyzed mortality data from the São Paulo State Data Analysis System, selecting all death certificates on which DM or PM was listed as a cause of death. The variables sex, age and underlying, associated or total mentions of causes of death were studied using mortality rates, proportions and historical trends. Statistical analysis were performed by chi-square and H Kruskal-Wallis tests, variance analysis and linear regression. A p value less than 0.05 was regarded as significant. RESULTS Over a 23-year period, there were 318 DM-related deaths and 316 PM-related deaths. Overall, DM/PM was designated as an underlying cause in 55.2% and as an associated cause in 44.8%; among 634 total deaths females accounted for 71.5%. During the study period, age- and gender-adjusted DM mortality rates did not change significantly, although PM as an underlying cause and total mentions of PM trended lower (p < 0.05). The mean ages at death were 47.76 ± 20.81 years for DM and 54.24 ± 17.94 years for PM (p = 0.0003). For DM/PM, respectively, as underlying causes, the principal associated causes of death were as follows: pneumonia (in 43.8%/33.5%); respiratory failure (in 34.4%/32.3%); interstitial pulmonary diseases and other pulmonary conditions (in 28.9%/17.6%); and septicemia (in 22.8%/15.9%). For DM/PM, respectively, as associated causes, the following were the principal underlying causes of death: respiratory disorders (in 28.3%/26.0%); circulatory disorders (in 17.4%/20.5%); neoplasms (in 16.7%/13.7%); infectious and parasitic diseases (in 11.6%/9.6%); and gastrointestinal disorders (in 8.0%/4.8%). Of the 318 DM-related deaths, 36 involved neoplasms, compared with 20 of the 316 PM-related deaths (p = 0.03). CONCLUSIONS Our study using multiple cause of deaths found that DM/PM were identified as the underlying cause of death in only 55.2% of the deaths, indicating that both diseases were underestimated in the primary mortality statistics. We observed a predominance of deaths in women and in older individuals, as well as a trend toward stability in the mortality rates. We have confirmed that the risk of death is greater when either disease is accompanied by neoplasm, albeit to lesser degree in individuals with PM. The investigation of the underlying and associated causes of death related to DM/PM broaden the knowledge of the natural history of both diseases and could help integrate mortality data for use in the evaluation of control measures for DM/PM.

Abstract
The aim of this study was to define the standardized incidence ratio (SIR) of malignancy and the potential risk factors of concomitant malignancies in patients with inflammatory myopathies, including clinically amyopathic dermatomyositis (CADM). A total of 145 patients diagnosed with either dermatomyositis/polymyositis (DM/PM) or CADM at our institute between 1984 and 2002 were enrolled in the study. The demographic, clinical and laboratory features of the patients at the time of DM/PM or CADM diagnosis were compared between patients with and without malignancies, respectively. Multivariate analysis by logistic regression was used to determine the independent risk factors for the development of malignancies in DM/PM patients. Malignancy was found in 17 of 70 patients with DM (24%), three of 15 patients with CADM (20%), and three of 51 patients with PM (6%). Gastric cancer (8/23) was the most common malignancy. Compared with general population, the SIR of malignancies was 13.8 (range 9.0-21.1). The patients who developed malignancies were older (61.5 vs. 51.1 years; P < 0.005), presented more often with dysphagia (61 vs. 15%; P < 0.0001) and were less likely to have the complication of interstitial lung disease (30 vs. 60%; P < 0.05). These features were independent predictive factors for developing malignancies in multiple logistic regression analysis. The results of our study confirm that CADM in addition to DM was associated with high rates of malignancy among our patient cohort.

Abstract
To describe demographic characteristics, clinical features and outcome of Jordanian patients with idiopathic inflammatory myopathies (IIM), a retrospective chart review of all patients diagnosed with IIM at Jordan University Hospital between 1996 and 2009 was carried out. Thirty patients with IIM were identified. Female to male ratio was 1.7:1, with mean age at diagnosis 34.3 ± 9.2 (10-72) years with bimodal presentation at 21 and 49 years and a mean follow-up of 6.5 ± 5.7 years. Eleven patients had polymyositis (PM); 19 patients had dermatomyositis (DM); 1 patient had DM with malignancy; 2 patients had juvenile DM; and 2 patients had DM/PM with other rheumatologic diseases. Raynaud's phenomenon was present in 26% of patients, dysphagia in 40%, fever in 16%, arthralgia/arthritis in 26%, and dyspnea was present in 26% patients. Positive muscle biopsy and EMG were present in 81% and 92% of patients, respectively. Elevated serum creatinine kinase (CK), AST/ALT and LDH were found in 90%, 72%, and 88% of patients at presentation, respectively. Interstitial fibrosis identified on high-resolution computed tomography (HRCT) was found in 7/14 (50%) patients. Restrictive lung disease was present in 16/21 (76%), low diffusion capacity of lung of carbon monoxide (DLCO) in 10/17 (59%) and pulmonary hypertension in only 3/19 (16%) patients tested. Arab Jordanian patients with IIM showed very low prevalence of malignancy, lower mean age than previous reports, and similar other clinical, laboratory and serologic markers, and survival rate to previous reports. Of interest, we found that extra-muscular manifestations were mainly associated with dermatomyositis.

Abstract
Approximately 33% of adult patients with dermatomyositis develop malignancy with up to 42% presenting after the diagnosis has been made; careful evaluation for malignancy is often undertaken at the time of dermatomyositis diagnosis. This phenomenon has rarely been noted in pediatric patients and extensive workup for malignancy is not indicated in pediatric patients. In 1993, 6 cases were reported in which juvenile dermatomyositis/polymyositis (JDM/PM) appeared to be part of a paraneoplastic phenomenon. Our objective was to update the literature for reported cases of malignancy associated with JDM/PM; we reviewed the literature over the last 15 years and located 6 additional cases. In 9 of 12 reported patients an unusual physical finding such as splenomegaly or lymphadenopathy was noted at the time of diagnosis, and in the entire group, the malignancy occurred within a mean of 12 months. It is less likely that JDM/PM in pediatric patients is a paraneoplastic phenomenon as it is in adult patients. However, if the physical examination at the time of diagnosis of JDM/PM is atypical the presence of malignancy must be considered and a more in-depth evaluation to rule out malignancy should be performed prior to the initiation of treatment.

Abstract
PURPOSE OF REVIEW It has been recognized for some time now, that compared with the normal population, patients with idiopathic inflammatory myopathies (IIM) live with an increased risk of developing malignancy. In the majority of these patients, cancer-associated myositis appears to have some paraneoplastic features. The aim of the present review is to describe new data that explain the connection between myositis and malignant diseases, as well as to highlight its value in the current management of these patients. RECENT FINDINGS Antigen expressions and patterns shared by regenerating muscle and cancers raise questions about whether myositis cases without clinically observable cancer may represent a fully successful antitumor immune response with bystander damage to regenerating muscle. The discovery of anti-155/140 autoantibody may aid in the better diagnosis of adult IIM patients with a higher risk of malignancy. It also may help the better understanding of paraneoplastic myositis. SUMMARY Cancer-associated myositis differs from primary myositis in many aspects. Prognosis and life-expectancy are determined by the underlying malignancy. Therefore, patient-specific examinations for detection of an underlying cancer are important in the management of patients. Recent clinical findings and new possibilities in immunoserological testing may result in the elaboration of an evidence-based recommendation for cancer screening programs in patients with IIM in the future.

Abstract
BACKGROUND The inflammatory myopathies are a group of acquired diseases characterized by a proximal myopathy caused by an inflammatory infiltrate of the skeletal muscle. The three major diseases are dermatomyositis, polymyositis and inclusion body myositis. AIMS To review the gastrointestinal manifestations of myositis. METHODS Over 110 articles in the English literature were reviewed. RESULTS Dysphagia to solids and liquids occurs in patients with myositis. The pharyngo-oesophageal muscle tone is lost and therefore patients develop nasal speech, hoarseness, nasal regurgitation and aspiration pneumonia. There is tongue weakness, flaccid vocal cords, poor palatal motion and pooling of secretions in the distended hypopharynx. Proximal oesophageal skeletal muscle dysfunction is demonstrated by manometry with low amplitude/absent pharyngeal contractions and decreased upper oesophageal sphincter pressures. Patients exhibit markedly elevated creatine kinase and lactate dehydrogenase levels consistent with muscle injury. Myositis can be associated with inflammatory bowel disease, coeliac disease and interferon treatment of hepatitis C. Corticosteroids and other immunosuppressive drugs comprise the mainstay of treatment. Inclusion body myositis responds poorly to these agents and therefore a myotomy is usually indicated. CONCLUSION Myositis mainly involves the skeletal muscles in the upper oesophagus with dysphagia, along with proximal muscle weakness.

Abstract
Gastric adenocarcinoma developing concomitantly with a lymphoma is rare. Furthermore, B-cell lymphoma, originating from lymph nodes, with eosinophilia is extremely rare. We report here a case with a synchronous diffuse large B-cell lymphoma (DLBCL) and an early adenocarcinoma of the stomach. In addition, this case seemed to be associated with paraneoplastic cutaneous vasculitis caused by hypereosinophilic syndrome (HES) with mixed cryoglobulinemia (MC). Many neoplastic diseases that affect internal organs display cutaneous manifestations, which may be the presenting signs and symptoms of the underlying malignancy. In particular, the association between cutaneous vasculitis and malignancy has been widely reviewed, and recently neoplasms have been suggested to produce antigens and the resultant immune complex formations, activating the serum complement, thus cause paraneoplastic vasculitis. In this case, severe eosinophilia and cryoglobulinemia with low complements were observed in a laboratory test. A biopsy specimen from a skin lesion revealed leukocytoclastic vasculitis with severe perivascular infiltration of eosinophils. The cutaneous vasuculitis was considered to be a manifestation of HES with MC, although there were no etiological factors of HES and MC. Therefore, the vasculitis seems to be a symptom of paraneoplastic syndrome in this case. Our finding suggests that the potential presence of malignancies should be kept in mind as a possible underlying disorder especially in the presence of HES with MC; this possibility is interesting also as regards at least part of the pathogenesis for paraneplastic syndrome.

Abstract
There is a greater risk of developing cancer among patients with inflammatory myositis, specifically dermatomyositis. This relationship was first described in 1916 by Sterz and has been corroborated in population based studies. This chapter describes clinical and serological characteristics of patients with myositis and cancer, as well as the most common malignancies and diagnostic and prognostic considerations in this group of patients.

Abstract
INTRODUCTION To study the clinical features and the outcome of polymyositis (PM) and dermatomyositis (DM) in Tunisia. METHODS Retrospective multicentre study conducted by the Tunisian Society of Internal Medicine. Adult patients with confirmed and probable PM and DM, according to the Bohan and Peter's criteria, were included in the study and followed-up between 1987 and 2005. RESULTS Twenty cases of PM and 50 cases of DM were included. Female/male sex-ratio was 2.5. The mean age at diagnosis was 40.7 years. Muscle weakness concerned girdle muscles in 94.3% and pharyngeal muscles in 42.8% of the patients. Interstitial lung disease and heart involvement occurred respectively in 35.7 and 20%. Eyelid erythema, peri-ungual erythema and Gottron's sign occurred in respectively 86, 50 and 36% of the cases of DM. Malignant disease was found in 12.8% of the patients (mainly gynecological and nasopharyngeal cancers). All patients received high dose corticosteroids with additional immunosuppressive drugs in 40% of the cases. The outcome was stabilization or partial improvement in 71.5% of the cases. Death occurred in 20% and was caused by respiratory failure, sepsis and cardiac failure. CONCLUSION The particularities of PM and DM in Tunisia are the preponderance of DM, early onset of the disease and high frequency of the nasopharyngeal cancer.

Abstract
The association between dermatomyositis (DM) and various types of malignancies has been reported in several studies, with an estimated frequency of about 20-25%. Cancer may appear before the onset of DM, concurrently with DM or after its onset. In the present report, the occurrence of typical DM in concomitance with development of skin metastases from previously treated breast cancer is described, suggesting the role of DM as paraneoplastic marker not only in association with the primary tumor but also in case of cutaneous involvement by cancer.

Abstract
The inflammatory myopathies are a group of acquired diseases, characterized by an inflammatory infiltrate of the skeletal muscle. On the basis of clinical, immuno-pathological and demographic features, three major diseases can be identified: dermatomyositis (DM); polymyositis (PM); and inclusion body myositis (IBM). New diagnostic criteria have recently been introduced, which are crucial for discriminating between the three different subsets of inflammatory myopathies and for excluding other disorders. DM is a complement-mediated microangiopathy affecting skin and muscle. PM and IBM are T cell-mediated disorders, where CD8-positive cytotoxic T cells invade muscle fibres expressing MHC class I antigens, thus leading to fibre necrosis. In IBM, vacuolar formation with amyloid deposits are also present. This article summarizes the main clinical, laboratory, electrophysiological, immunological and histologic features as well as the therapeutic options of the inflammatory myopathies.

Abstract
The idiopathic inflammatory myopathies (IIMs) comprise polymyositis, myositis overlapping with another connective tissue disease, dermatomyositis (DM) and inclusion-body myositis (IBM). IIMs are characterized by the presence of proximal muscle weakness, increased levels of muscle-specific enzymes, specific electromyographic abnormalities, and the presence of inflammatory cell infiltrates in skeletal muscle. Clinical, serological and histological criteria can be used to define individual IIM subtypes. In the first of this two-part review series, we examine the evidence for the existence of cancer-associated myositis (CAM), and in part 2, we discuss recent discoveries that provide insight into identification of patients with DM, who may be most at risk of developing CAM.

Abstract
Demographic, clinical, and laboratory features that predict underlying malignancy in patients with dermatomyositis (DM) are poorly known. We conducted a retrospective study in all adult patients with a definite (n = 75) or probable (n = 32) diagnosis of DM according to Bohan and Peter criteria or with amyopathic DM (n = 14) who were referred to 2 departments during a 13-year period. The diagnosis of malignancy-associated DM was retained if DM occurred in a context of recently diagnosed malignancy or if a malignancy was diagnosed during the 5 years following the diagnosis of DM. The Kaplan-Meier method was used to assess the cumulative incidence rates of underlying malignancy during the first 5 years of DM. Factors associated with malignancy in patients with DM were identified by Cox proportional hazards models. During the study period, 121 patients fulfilled the inclusion criteria (median age, 52 yr; range, 19-77 yr; women: 70%). For 29 of them, the diagnosis of malignancy-associated DM was retained. The cumulative incidence rate of malignancy was 21 +/- 4% and 28 +/- 5%, 1 year and 5 years after the diagnosis of DM, respectively. The median duration of follow-up of the 92 patients with no malignancy diagnosed was 36 months (range, 1-140 mo). In multivariate analysis, independent factors associated with an underlying malignancy in patients with DM were an age at diagnosis >52 years (hazard ratio [HR], 7.24; 95% confidence interval [CI], 2.35-22.31), a rapid onset of skin and/or muscular symptoms (HR, 3.11; 95% CI, 1.07-9.02), the presence of skin necrosis (HR, 3.84; 95% CI, 1.00-14.85) or periungual erythema (HR, 3.93; 95% CI, 1.16-13.24), and a low baseline level of complement factor C4 (HR, 2.74; 95% CI, 1.11-6.75). Lastly, low baseline lymphocyte count (<1500/mm(3)) was a protective factor of malignancy (HR, 0.33; 95% CI, 0.14-0.80). Taken together, these data may help physicians focus on a group of patients who might benefit from extensive evaluation for malignancy.

Abstract
Malignancy and interstitial lung disease (ILD) are 2 conditions associated with dermatomyositis (DM) that are responsible for a significant portion of the morbidity and mortality related to this disease; however, they rarely occur in the same patient. The antisynthetase syndrome consists of several characteristics, including ILD, arthritis, Raynaud phenomenon, "mechanic's hands," and positive antibodies to tRNA synthetases, which have each been negatively associated with cancer. When patients with DM present with such characteristics, clinicians may be falsely reassured that a thorough malignancy screen is unnecessary. We describe a patient who presented with the antisynthetase syndrome and was subsequently found to have colon cancer. Removal of the cancer led to resolution of the myositis and lung disease, but the patient's rash and arthritis persisted and ultimately required immunosuppressive therapy. We provide a review of the literature describing the concurrence of both this syndrome and ILD alone, with malignancy. We conclude that a thorough and expedited age-appropriate malignancy work up is indicated in all patients with a new diagnosis of DM, despite the presence of disease characteristics that are usually not associated with cancer.

Abstract
Dermatomyositis (DM) is an idiopathic inflammatory myopathy. The mainstay of treatment for DM is oral corticosteroids. However, the dose and length of treatment is debated. Adding to the confusion, there have been no randomized controlled studies comparing the use of various corticosteroid doses and taper rates, and no controlled long-term studies assessing the hypothesis that, unlike systemic lupus erythematous, patients with DM can often achieve long-term remission off therapy. This literature review supports an approach that prednisone should be started at about 1 mg/kg/d, which is then tapered slowly based on the response. As patients respond differently to prednisone, additional therapies may be necessary. When to initiate these therapies requires clinical judgment. In addition, as we learn more about the pathophysiology of DM, newer medications that target specific mechanisms in the immune response may help us better treat the disease. Evidence-based data with long-term follow-up will allow for selection of the best treatment to maximize long-term remission, not simply short-term lowering of the systemic corticosteroid dose.

Abstract
PURPOSE OF REVIEW To examine recent data about the association between rheumatic disorders and cancer. This article focuses on paraneoplastic rheumatic disorders, which usually precede by a short period of time the diagnosis of malignancy, and on malignant transformation, which occurs late in the course of rheumatic disorders. Evidence of causality between malignancies and rheumatic disorders was reviewed based on statistical indicators (standardized incidence ratios and odds ratios) and by applying Bradford Hill's criteria of causality. RECENT FINDINGS Firm epidemiological evidence was found attesting that dermatomyositis and polymyostis may present as paraneoplastic syndromes. Several other musculoskeletal disorders may be present akin to paraneoplastic syndrome, based on clinicians' impressions, but with scarce epidemiological evidence supporting a causal determinism. In contrast, robust evidence has accumulated on the role of longstanding rheumatoid arthritis, Sjögren's syndrome and systemic sclerosis as premalignant conditions. Evidence that systemic lupus erythematosus may evolve into lymphoma is equivocal. SUMMARY The link between malignancies and rheumatic disorders may impact on clinical practice. First, paraneoplastic rheumatic syndromes can provide the clinician with hints for earlier diagnosis of occult cancer. Second, the risk of malignant transformation during the course of rheumatic disorders may motivate the search for strategies aimed at prevention.
