BACKGROUND: Thyroid storm, an endocrine emergency, remains a diagnostic and therapeutic challenge. It is recognized to develop as a result of several factors, including infection, surgery, acute illness, and rarely, trauma. Recognition of thyroid storm in a trauma patient is difficult because the emergency physician usually focuses on managing more obvious injuries. OBJECTIVE OF THE REVIEW: We present a case of trauma-related thyroid storm and review the previous literature on posttraumatic thyroid storm to delineate risk factors of the disease...

BACKGROUND: Children with asthma may be less physically active than their healthy peers. We aimed to investigate if perceived exercise limitation (EL) was associated with lung function or bronchial hyperresponsiveness (BHR), socio-economic factors, prenatal smoking, overweight, allergic disease, asthma severity or physical activity (PA). METHODS: The 302 children with asthma from the 10-year examination of the Environment and Childhood Asthma birth cohort study underwent a clinical examination including perceived EL (structured interview of child and parent(s)), measure of overweight (body mass index by sex and age passing through 25kg/m(2) or above at18 years), exercise-induced bronchoconstriction (forced expiratory volume in one second (FEV1 ) pre- and post-exercise), methacholine bronchial challenge (severe BHR; provocative dose causing ≥20% decrease in FEV1≤1μmol) and asthma severity score (dose of controller medication and exacerbations last 12 months)...

Extracellular matrix metalloproteinase inducer (EMMPRIN, CD147) is a transmembrane glycoprotein that is upregulated on leukocytes in active lesions in multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). Administration of anti-EMMPRIN Abs reduces the severity of EAE. Minocycline is a tetracycline antibiotic with immune-modulatory properties that decreases the severity of EAE; it was recently found to attenuate the conversion from a first demyelinating event to clinically definite MS in a phase III trial...

Cutaneous T-cell Lymphoma (CTCL) is a rare non-Hodgkin's lymphoma that can affect the skin, blood, and lymph nodes, and can metastasize at late stages. Novel therapies that target all affected disease compartments and provide longer lasting responses while being safe are needed. One potential therapeutic target is NF-κB, a regulator of immune responses and an important participant in carcinogenesis and cancer progression. As a transcription factor, NF-κB targets genes that promote cell proliferation and survival...

Methotrexate forms one of the main drugs in the pharmacological management of rheumatoid arthritis, psoriasis, and some neoplastic diseases. Methotrexate rarely causes cutaneous ulceration and most cases are reported in patients with psoriasis and have been accompanied by pancytopenia. The author here reports occurrence of multiple (two) cutaneous ulcers due to methotrexate in a nonpsoriatic patient. The patient was on methotrexate for seronegative rheumatoid arthritis for 10 years. To the best of the Author's knowledge, this is a rare case of cutaneous ulceration due to methotrexate in a nonpsoriatic patient reported in the literature so far, and probably one of its kind without pancytopenia or other hematological abnormalities...

Strong evidence for the statistical association between radiation exposure and disease has been produced for thyroid cancer by epidemiological studies after the Chernobyl accident. However limitations of the epidemiological approach in order to explore health risks especially at low doses of radiation appear obvious. Statistical fluctuations due to small case numbers dominate the uncertainty of risk estimates. Molecular radiation markers have been searched extensively to separate radiation- induced cancer cases from sporadic cases...

Hemoglobin S (Hb-S) polymerization is the primary event in sickle cell disease causing irreversible damage to red blood cell (RBC) membranes over repeated polymerization cycles. A single polymerization triggered by a hypoxic environment was reported to result in reversibly (upon reoxygenation) decreased RBC deformability and increased mechanical fragility (MF). Individualized responses have not been reported, although RBC fragility can vary significantly even among healthy individuals. This study evaluates individual variability in response to a single hypoxia-induced sickling event, through changes in RBC MF...

Immune thrombocytopenia purpura (ITP) is characterized by the production of pathological autoantibodies that cause reduction in platelet counts. The disease can have serious medical consequences, leading to uncontrolled bleeding that can be fatal. Current widely used therapies for the treatment of ITP are non-specific and can, at times, result in complications that are more burdensome than the disease itself. In the present study, the use of platelet membrane-coated nanoparticles (PNPs) as a platform for the specific clearance of anti-platelet antibodies is explored...

Remarkable advances have been made in the treatment of inflammatory bowel disease (IBD) since the introduction of anti-tumor necrosis factor (TNF)-α agents, especially for patients who are refractory to or cannot tolerate conventional therapies. Currently, infliximab, adalimumab, and golimumab are available in the East Asian medical market, and these agents have been shown to be effective for inducing and maintaining long-term remission of IBD. Despite their clinical benefits, anti-TNF therapy can also lead to increased vulnerability to infections, development of autoimmune diseases and malignancy, and decreased immunogenicity of vaccinations...
