Context: Cardiac dysfunction is one of the most serious consequences of scorpion envenomation. The best tool to evaluate cardiac function is echocardiography, but it is not available at all emergency departments. Many studies aimed to describe biological predictive factors of cardiac dysfunction in scorpion envenomation. Troponin is one of these biomarkers but its correlation with myocarditis is not well established. The aim of this study was to evaluate correlation between troponin levels and cardiac dysfunction in moderate scorpion envenomation. Methods: A retrospective monocentric study including patients admitted in the emergency department for moderate scorpion envenomation with troponin measurement during their early management. On arrival, an electrocardiogram and a chest X-ray were realized for all patients. Results: We enrolled 132 patients with a mean age at 31.3 ± 24.4 years and a 1.35 sex-ratio. All patients had moderate systemic manifestations. There were 28 patients with clinical manifestations of cardiac dysfunction without life-threatening troubles (21.2%). Troponin was undetectable in 69 patients (56%). The mean value of troponin level (pg/ml) was higher in patients with clinical manifestations of left ventricular dysfunction (1.80 ± 3.8 vs. 0.11 ± 0.5; p = 0.02). Troponin levels were significantly higher in patients with positive T wave on electrocardiogram. Conclusion: In patients with moderate scorpion envenomation with positive T wave, high values of troponin suggest the presence of cardiac dysfunction.

Canine distemper is a multisystemic contagious viral disease having a worldwide distribution, a high mortality rate, and significant central neurologic system (CNS) complications. In its systemic manifestations, it is often presumptively diagnosed on the basis of clinical signs and history. Few definitive antemortem diagnostic tests exist, and most are limited to the detection of viral antigen by immunofluorescence techniques on tissues or cytologic specimens or high immunoglobulin levels in CSF (cerebrospinal fluid). Diagnosis of CNS distemper is often unreliable due to the relatively low cell count in CSF (<50 cells/μl) and the binding of blocking immunoglobulins in CSF to cell surfaces. A more reliable and definitive test might be possible utilizing direct morphologic detection of the etiologic agent. Distemper is the canine equivalent of human measles, in that both involve a closely related member of the Paramyxoviridae, both produce mucosal inflammation, and may produce CNS complications. In humans, diagnosis of measles-induced subacute sclerosing panencephalitis is through negative stain identification of whole or incomplete viral particles in patient CSF.

Inflammatory myopathies are chronic, immune-mediated diseases characterized with progressive proximal muscle weakness. They encompass a variety of syndromes with protean manifestations. The aims of therapy are to increase muscle strength, prevent the development of contractures, and to manage the systemic manifestations of the disease. This is a complex treatment which requires routine and wide knowledge. The most important task is to recognize the disease and guide the patient to immunologic center. Although the first line of therapy continues to include corticosteroids, there are a multitude of agents available for treating patients with myositis. There are several different immunosuppressive agents which may be applied alone or in combination with each other, as well as an increasing number of novel and exciting biologic agents targeting molecules participating in the pathogenesis of inflammatory myopathy. Physiotherapy and rehabilitation in the remission period may significantly improve the functional outcome of patients with these disorders. Orv. Hetil., 2011, 152, 1552–1559.

Drug-induced lupus erythematosus has features distinct from primary systemic lupus erythematosus. It can occur with a wide variety of agents that result in the generation of anti-histone or other types of antibodies. Systemic manifestations of drug-induced systemic lupus erythematosus may include renal dysfunction due to circulating immune complexes or due to other immune reactions to the culprit medication(s). Acute interstitial nephritis occurs due to DNA–drug or protein–drug complexes that trigger an allergic immune response. We report a patient who developed acute kidney injury, rash, and drug-induced systemic lupus diagnosed by serologies after starting chlorthalidone and amiodarone. A renal biopsy showed acute interstitial nephritis and not lupus-induced glomerulonephritis. It is important to note that systemic lupus erythematosus and acute interstitial nephritis can occur together, and this report highlights the role of the kidney biopsy in ascertaining the pathological diagnosis and outlining therapy in drug-induced lupus erythematosus.

Abstract Scorpion envenomation is a leading cause of morbidity and mortality among accidents caused by venomous animals. Major clinical manifestations that precede death after scorpion envenomation include heart failure and pulmonary edema. Here, we demonstrate that cardiac dysfunction and fatal outcomes caused by lethal scorpion envenomation in mice are mediated by a neuro-immune interaction linking IL-1 receptor signaling, prostaglandin E2, and acetylcholine release. IL-1R deficiency, the treatment with a high dose of dexamethasone or blockage of parasympathetic signaling using atropine or vagotomy, abolished heart failure and mortality of envenomed mice. Therefore, we propose the use of dexamethasone administration very early after envenomation, even before antiserum, to inhibit the production of inflammatory mediators and acetylcholine release, and to reduce the risk of death.

Background:Numerous joint disorders initially produce swelling in a single joint and new onset monoartritis will probably further lead to the involvement of other joint groups and development of extraarticular manifestations. It is essential to take a proper diagnostic approach for organizing appropriate treatment and lowering possibility of disease progression.Objectives:The aim of this study was to investigate joint distribution, determine rheumatological diseases of patients with acute monoarthritis and reveal the development of further systemic manifestations.Methods:100 patients (age 18-75 years) with clinically apparent monoarthritis of less than 6 weeks duration were included in the study. Criteria of exclusion were infection, trauma and crystal induced arthritis. Joint distribution, presence of systemic manifestations and development of chronic inflammatory rheumatic disease were evaluated. Presence of arthritis was proved with help of ultrasound examination. Complete blood count, ESR, CRP, RF, anti-CCP; HLAB27; MEFV mutations and X-ray of swollen joint were performed for all patients. Temperature was also measured.Results:Mean age of patients with acute monoarthritis was 46±13 years. Female predominance was noted (61%). 71% of patients had elevated ESR, 69%- CRP. In 24% of cases homozygous or heterozygous mutations of MEFV gene were revealed. 21% of patients had positive RF and 18% - anti-CCP. 11% patients carried HLA-B27 antigen. 28% of examined patients had subfebril fever. Hepatosplenomegaly was determined in 16%, uveitis in 5%, psoriatic plaque in 4%, interstitial pneumonia in 2% of casesAt the baseline 82 patients were diagnosed with rheumatologically disease. Baseline data is shown in the Table 1 bellow.Table 1.Baseline dataDiagnosis Number of patientsFMF23Osteoarthritis (reactive synovitis)16Rheumatoid arthritis15Reactive arthritis10Ankylosing spondylitis6Psoriatic arthritis4SLE3Schonleyn-Henoch purpura2Sarcoidosis2Behcet diseases1Conclusion:In this study monoarhtritis in majority of cases underlies FMF. Though FMF is not considered as a frequent cause of acute monoarthritis, more attention should be paid on this pathology in focus of monoarthritis, especially in specific for FMF region. Further follow up of acute monoarthritis progression is needed.References:[1]A. Becker, J. Daily, K. Pohlgeers. Acute Monoarthritis: Diagnosis in Adults.Am Fam Physician 2016; 94(10): 810-816[2]S.

This study aimed to achieve a better understanding of the epidemiological and clinical characteristics of multisystem inflammatory syndrome in children (MIS-C) following coronavirus disease 2019 (COVID-19). We searched PubMed and Embase between December 2019 and March 2021 and included only peer-reviewed clinical studies or case series. The proportions of patients who had conjunctivitis, systemic symptoms/signs (s/s), Kawasaki disease (KD), and exposure history to suspected/confirmed COVID-19 cases were obtained. Moreover, positive rates of the nasopharyngeal real-time reverse transcriptase polymerase chain reaction (RT-PCR) and serum antibody for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were recorded. Overall, 32 studies with 1458 patients were included in the pooled analysis. Around half of the patients had conjunctivitis. The five most common systemic manifestations were fever (96.4%), gastrointestinal s/s (76.7%), shock (61.5%), rash (57.1%), and neurological s/s (36.8%). Almost one-third presented complete KD and about half had exposure history to COVID-19 cases. The positivity of the serology (82.2%) was higher than that of the nasopharyngeal RT-PCR (37.0%). MIS-C associated with COVID-19 leads to several features similar to KD. Epidemiological and laboratory findings suggest that post-infective immune dysregulation may play a predominant role. Further studies are crucial to elucidate the underlying pathogenesis.
