Rothia muciloginosa is a member of normal flora and rarely causes invasive disease. Immunosupressed patients have increased risk for severe infection. Here, we report a male patient with relapsed neuroblastoma hospitalized for pneumonia. After clinical improvement, patient's respiratory symptoms worsened again. Rothia muciloginosa was isolated from blood culture. The worsening of respiratory symptoms can be explained by hematogenous spread of bacteria. He was successfully treated with meropenem and vancomycin for 14 days...

Mycobacterium tuberculosis (Mtb) latent infection can lead to reactivation. The design of new strategies to prevent it is an important subject. B6D2F1 mice were infected intratracheally with a low dose of Mtb H37Rv to induce chronic infection. After 7 months, mice were treated with one dose of recombinant adenoviruses encoding TNFα, β defensin-3 and LL37. Immunosupression was induced 1 month later with corticosterone. In comparison with the control group, mice treated with adenoviruses showed significantly less bacterial load and pneumonia, the adenoviruses encoding TNFα and LL37 being the most efficient...

For more than a century, scientists have tried to exploit the anti-tumoral potential of the immune system to treat cancer. However, for decades all the efforts made in favor of the development of cancer immunotherapy has not had the expected clinical results. Instead, classical anti-neoplastic treatments such as surgery, radiotherapy, and chemotherapy used to be the first line of treatment. Lately, this scenario is changing, particularly with the identification of immune checkpoints inhibitors. Now more than ever, understanding how cancer cells can modulate the immune system has become a matter of great importance...

Rheumatoid arthritis (RA) is a chronic, inflammatory, autoimmune disease of unidentified etiology that affects the joints and causes pain, swelling, stiffness and redness in the joints. The exact cause of rheumatoid arthritis has not yet been discovered and, consequently, treatment methods have not been optimally effective. It has long been treated with anti-inflammatory and immunosupressants including modern biologics either alone or in combination but all of the drugs have severe life threatening consequences with impaired immune function due to nonspecific targeting...

Clinically amyopathic dermatomyositis (CADM) is an extremely rare entity in childhood and only 75 cases have been described in the literature. These patients present mild or no muscle involvement, while skin involvement is similar to that seen in classic dermatomyositis (DM). Systemic inflammatory vasculopathy is a hallmark of juvenile dermatomyositis (JDM), especially affecting the microcirculation. Nailfold capillaroscopy (NFC) is a non-invasive method that allows direct visualization of nailfold capillary loops around the proximal edge of the finger nails...
