Anti-MDA5-Positive Dermatomyositis Presenting as Fever of Unknown Origin

et al. 2016

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 VietnameseAmerican 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. CASE PRESENTATIONA 51-year-old Vietnamese-American male industrial engineer was admitted to the medical ward for evaluation of fever of unknown origin (FUO). He reported 3 weeks of fever, fatigue, generalized weakness, and dyspnea. His past medical history included a remote 10-pack-year history of cigarette smoking and latent tuberculosis treated with 9 months of isoniazid treatment, completed 5 years prior. He had moved from Vietnam to the United States 30 years earlier and denied any recent travel, sick contacts, or insect bites. Physical examination revealed a fatigued man, with a temperature of 38.1°C, pulse of 108 beats/minute, respiratory rate of 28 breaths/minute, and room air oxygen saturation of 96 %. Oropharyngeal, neurologic, pulmonary, cardiac, musculoskeletal, and skin evaluation were otherwise normal.A complete blood count (CBC) revealed anemia (hemoglobin 12.3 g/dL, hematocrit 38.5 %). White blood cell counts, platelet counts, and the basic metabolic panel were normal. Erythrocyte sedimentation rate (ESR) was 97 mm/hr and C-reactive protein (CRP) was 5.7 mg/dL. Muscle enzymes, sent to evaluate his weakness in the setting of elevated inflammatory markers, showed normal creatine kinase (CK) at 44 units/liter and mildly elevated aldolase to 9.4 U/L (normal: < 7.7 U/L). Blood, urine, and sputum cultures had no growth. Chest x-ray (CXR) demonstrated low lung volumes with increased reticular markings, small bilateral pleural effusions, and bibasilar opacities. During the hospitalization, he continued to have intermittent fevers as high as 39.1°C, generalized weakness, and dyspnea. Additionally, he developed bibasilar crackles on pulmonary exam and flat, diffuse, slightly hyperpigmented patches on his arms and chest that faded over several days. Extensive workup for infectious, inflammatory, and malignant causes of fever was unrevealing, including negative viral hepatitis serologies, human immunodeficiency virus antibody, anti-nuclear antibody (ANA), and anti-...

“…According to Stanton, Chambers & Piggott (2001), three definitions and their associated theoretical perspectives dominate. These are the three-level model (Endsley, 1995a), the perceptual cycle model (Smith & Hancock 1995) and the activity theory model (Bedny & Meister 1999).…”

Situation awareness measurement: A review of applicability for C4i environments

et al. 2006

The construct of situation awareness (SA) has become a core theme within the human factors (HF) research community. Consequently, there have been numerous attempts to develop reliable and valid measures of SA. Despite this, it is apparent that there are a lack of techniques that have been developed specifically for the assessment of SA in C4i (command, control, communication, computers and intelligence) environments.During the design, development and evaluation of novel systems, technology and procedures, valid and reliable situation awareness measurement techniques are required for the assessment of individual and team SA. SA is assessed in order to determine the improvements (or in some cases decrements) resulting from proposed design and technological interventions. The following paper presents a review of existing situation awareness measurement techniques conducted in order to assess their suitability for use in the assessment of SA in C4i environments. Seventeen SA measures were evaluated against a set of HF methods criteria. It was concluded that current SA measurement techniques are inadequate for use in the assessment of SA in C4i environments, and a multiple-measure approach utilising different approaches is recommended.

“…The positive response to the use of the visual feedback system is encouraging because based on human factors principles the light feedback should improve attention (Lynas &Horberry, 2011 andStanton, Chambers, &Piggott, 2001). The light feedback increases task attention spatially and temporally as well as providing feedback redundancy in conjunction with the bolter motion itself (Wogalter & Mayhorn, 2005).…”

Problem-Operators of roof bolting machines in underground coal mines do so in confined spaces and in very close proximity to the moving equipment. Errors in the operation of these machines can have serious consequences, and the design of the equipment interface has a critical role in reducing the probability of such errors.Methods-An experiment was conducted to explore coding and directional compatibility on actual roof bolting equipment and to determine the feasibility of a visual feedback system to alert operators of critical movements and to also alert other workers in close proximity to the equipment to the pending movement of the machine. The quantitative results of the study confirmed the potential for both selection errors and direction errors to be made, particularly during training.Results-Subjective data confirmed a potential benefit of providing visual feedback of the intended operations and movements of the equipment.Impact-This research may influence the design of these and other similar control systems to provide evidence for the use of warning systems to improve operator situational awareness.
