    Evolution, immunity and the emergence of brain superautoantigens.
    F1000Res 2017 21;6:171. Epub 2017 Feb 21.
    Bank of Tissues and Cells, Lyon University Hospital (Hospices Civils de Lyon), CarMeN Laboratory, INSERM 1060, INRA 1397, INSA Lyon, Université Claude Bernard Lyon-1, Lyon, F-69000, France.
    While some autoimmune disorders remain extremely rare, others largely predominate the epidemiology of human autoimmunity. Notably, these include psoriasis, diabetes, vitiligo, thyroiditis, rheumatoid arthritis and multiple sclerosis. Thus, despite the quasi-infinite number of "self" antigens that could theoretically trigger autoimmune responses, only a limited set of antigens, referred here as superautoantigens, induce pathogenic adaptive responses.

    A Case of Sweet's Syndrome Secondary to Myelodysplastic Syndrome - Diagnostic and Treatment Challenges.
    Maedica (Buchar) 2016 Jun;11(2):154-157
    Department of Onco-hematology, "Maria Sklodowska Curie" Children's Emergency Hospital, Bucharest, Romania.
    Sweet's Syndrome also knows as acute febrile neutrophilic dermatosis, is a rare skin's condition, that can occur either idiopathic or secondary. In the case of the latter, the syndrome can develop after certain malignancies (paraneoplastic syndrome), because of exposure to some medication or post infectious. It is more frequent in women aged between 30 and 50 years, but concerning children, the disorder is extremely rare (8% of the total number of cases), having equal sex ratio distribution. Read More

    Octreotide is Ineffective in Treating Tumor-Induced Osteomalacia; Results of a Short-Term Therapy.
    J Bone Miner Res 2017 Apr 29. Epub 2017 Apr 29.
    Skeletal Clinical Studies Unit, Craniofacial and Skeletal Disease Branch, National Institute of Dental and Craniofacial Research, National Institutes of Health, Bethesda, MD, USA.
    Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome in which unregulated hypersecretion of fibroblast growth factor 23 (FGF23) by phosphaturic mesenchymal tumors (PMT) causes renal phosphate wasting, hypophosphatemia, and osteomalacia. The resulting mineral homeostasis abnormalities and skeletal manifestations can be reversed with surgical resection of the tumor. Unfortunately, PMTs are often difficult to locate, and medical treatment with oral phosphate and vitamin D analogues is either insufficient to manage the disease or not tolerated. Read More

    Cancer is a propagandist.
    Stud Hist Philos Biol Biomed Sci 2017 Jun 11;63:28-31. Epub 2017 Apr 11.
    Department of Kinesiology and Nutrition, University of Illinois at Chicago, Chicago, IL, USA. Electronic address:
    Communication among cells (also known as cross-talk) plays a prominent role in the current knowledge of the pathophysiology of cancer and of cancer-associated conditions such as paraneoplastic syndromes and cachexia that are responsible for much of cancer's morbidity and mortality. Yet, biomedical scientists lack an explicit unifying frame that places this exchange of molecular information at the core of their understanding of cancer as a systemic disease. Propaganda is a type of information that aims at misleading, a form of communication intended primarily to serve the messenger. Read More

    An Unfortunate Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal Gammopathy, and Skin Change (POEMS).
    Cureus 2017 Mar 8;9(3):e1086. Epub 2017 Mar 8.
    Internal Medicine, University of Central Florida College of Medicine.
    POEMS syndrome is an acronym for polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes, which is a rare paraneoplastic disease of monoclonal plasma cells. A mandatory criterion to diagnose POEMS syndrome is the presence of a monoclonal plasma cell dyscrasia in which plasma cell leukemia is the most aggressive form. Early identification of the features of the POEMS syndrome is critical for patients to identify an underlying plasma cell dyscrasias and to reduce the morbidity and mortality of the disease by providing early therapy.

    Adaptive Immunity Is the Key to the Understanding of Autoimmune and Paraneoplastic Inflammatory Central Nervous System Disorders.
    Front Immunol 2017 23;8:336. Epub 2017 Mar 23.
    Department of Neurology, Neuroimmunology, University of Regensburg , Regensburg , Germany.
    There are common aspects and mechanisms between different types of autoimmune diseases such as multiple sclerosis (MS), neuromyelitis optica spectrum disorders (NMOSDs), and autoimmune encephalitis (AE) as well as paraneoplastic inflammatory disorders of the central nervous system. To our present knowledge, depending on the disease, T and B cells as well as antibodies contribute to various aspects of the pathogenesis. Possibly the events leading to the breaking of tolerance between the different diseases are of great similarity and so far, only partially understood. Read More

    CD4+ and CD8+ T cells are both needed to induce paraneoplastic neurological disease in a mouse model.
    Oncoimmunology 2017 9;6(2):e1260212. Epub 2016 Dec 9.
    INSERM UMR1043 - CNRS U5282, Centre de Physiopathologie Toulouse-Purpan, Toulouse, France; Université Toulouse III, Tolouse, France.
    Paraneoplastic neurological disorders (PNDs) are rare human autoimmune diseases that mostly affect the central nervous system (CNS). They are triggered by an efficient immune response against a neural self-antigen that is ectopically expressed in neoplastic tumors. Due to this shared antigenic expression, the immune system reacts not only to tumor cells but also to neural cells resulting in neurological damage. Read More

    Ectopic ACTH-producing large cell neuroendocrine Pancoast tumour presenting as Horner syndrome.
    BMJ Case Rep 2017 Mar 24;2017. Epub 2017 Mar 24.
    Department of Family Medicine, Apple Valley Medical Clinic, Apple Valley, Minnesota, USA.
    We present an interesting case where a patient is presented with a droopy left eyelid (as part of Horner syndrome) and Cushingoid features which were a result of a Pancoast tumour (apical lung tumour in superior pulmonary sulcus) involving the left lung. This tumour was secreting ectopic adrenocorticotropic hormone (ACTH), a paraneoplastic endocrine phenomenon, which resulted in Cushing syndrome symptomatology. Though most ectopic ACTH-producing lung cancers are either small cell or carcinoid tumours, this was in fact a large cell neuroendocrine cancer (LCNEC). Read More

    Acrokeratosis paraneoplastica Bazex (Bazex syndrome) is a rare paraneoplastic skin disease defined by erythematous, violaceous, scaly plaques on the hands and feet and on other acral locations such as nose and ears. Bazex syndrome is linked to a variety of underlying malignancies. Usually the skin lesions develop prior to the diagnosis of an internal malignant neoplasm with spontaneous remission after tumour removal. Read More

    Purpose: (18)F-fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) is a promising new tool for the identification of inflammatory, infectious, and neoplastic foci. The aim of our work was to evaluate the diagnostic value of FDG-PET/CT in patients treated on a neurological/neurosurgical ICU or stroke unit.

    Methods: We performed a single-center, 10-year, retrospective evaluation of the value of FDG-PET/CT in critically ill adult patients with severe neurological disease. Read More

    [Review of the psychiatric aspects of anti-NMDA (N-methyl-D-aspartic acid) receptor encephalitis, case report, and our plans for a future study].

    Anti-NMDAR (N-methyl-D-aspartic acid receptor) encephalitis, first described in 2007, is a rare, autoimmune limbic encephalitis. In half of the cases anti-NMDAR antibodies are paraneoplastic manifestations of an underlying tumor (mostly ovarian teratoma). In the early stage of the disease psychiatric symptoms are prominent, therefore 60-70% of the patients are first treated in a psychiatric department. Read More

    Thymoma-associated multi-organ autoimmunity: A case of graft-versus-host disease-like erythroderma complicated by Good syndrome successfully treated by thymectomy.

    Thymoma-associated multi-organ autoimmunity disease (TAMA) is a rare paraneoplastic disorder, clinicopathologically similar to graft-versus-host disease (GVHD). Many reported cases follow a difficult course; half of them die from serious infectious diseases subsequent to immunosuppression induced by chemotherapy for unresectable thymoma, or intensive therapies including systemic steroids for complicating autoimmune diseases and GVHD-like symptoms. We report a patient whose skin symptoms were improved subsequently to total thymectomy. Read More

    Objective: To identify cell-surface antibodies in patients with neuromyotonia and to describe the main clinical implications.

    Methods: Sera of 3 patients with thymoma-associated neuromyotonia and myasthenia gravis were used to immunoprecipitate and characterize neuronal cell-surface antigens using reported techniques. The clinical significance of antibodies against precipitated proteins was assessed with sera of 98 patients (neuromyotonia 46, myasthenia gravis 52, thymoma 42; 33 of them with overlapping syndromes) and 219 controls (other neurologic diseases, cancer, and healthy volunteers).
