The vitamin D pathway contributes to the microbicidal activity of macrophages against Leishmania infection. In addition induction this pathway, interferon-gamma (IFNγ), interleukin (IL)-15, and IL32γ are part a network pro-inflammatory cytokines. aim study was evaluate single-nucleotide polymorphisms (SNPs) in components associated cytokine genes that could be related resistance or susceptibility American tegumentary leishmaniasis (ATL). expressions IFNG, IL15, IL32, CYP27B1, VDR, other...

Diffuse cutaneous leishmaniasis (DCL) is characterized by disseminated lesions and the absence of a specific cellular immune response. Here, immunochemotherapy outcome patient with DCL from Amazonian Brazil infected Leishmania (Leishmania) amazonensis presented. After several unsuccessful chemotherapy treatment regimens many relapses, monthly immunotherapy scheme L. PH8 plus (Viannia) braziliensis M2903 monovalent vaccines associated Bacillus Calmette-Guerin (BCG) was established, one round...

The interleukin 32 (IL-32) is a proinflammatory cytokine produced by immune and non-immune cells. It can be induced during bacterial viral infections, but its production was never investigated in protozoan infections. American Tegumentary Leishmaniasis (ATL) caused Leishmania leading to cutaneous, nasal or oral lesions. aim of this study evaluate the expression IL-32 cutaneous mucosal lesions as well peripheral blood mononuclear cells (PBMC) exposed (Viannia) braziliensis. IL-32, tumour...

Background Sun exposure may lead to actinic keratoses (AKs), field cancerization, and skin cancer. Effective treatment of AKs cancerization is important. Oral topical retinoids can be used for this purpose. To compare clinical, histological, immunohistochemical effects oral retinoid on face upper limbs immunocompetent patients, as well the impact quality life, safety, tolerability. Methods This study compared 10 mg/day isotretinoin (ISO) 0.05% tretinoin cream (TRE) every other night,...

Leishmania (Viannia) braziliensis causes cutaneous and mucosal leishmaniasis in several countries Latin America. In mammals, the parasites live as amastigotes, interacting with host immune cells stimulating cytokine production that will drive type of specific responses. Generation Th17 lymphocytes is associated tissue destruction depends on IL-1β, IL-6, TGF-β IL-23 production, whereas IL-10 are protection. Here, we evaluate whether amastigotes stimulate peripheral blood mononuclear (PBMCs)...

Isolation of Leishmania parasite and species identification are important for confirmation to help define the epidemiology leishmaniasis. Mice often used isolate pathogens, but most common mouse strains resistant infection with parasites from (Viannia) subgenus. In this study we tested inoculation interferon gamma knockout (IFNgamma KO) mice biopsy macerates Leishmania-infected patients increase possibility isolating parasites. Biopsies twenty five clinical signs leishmaniasis were taken...

Interleukin-32 is a novel inflammatory mediator that has been described to be important in the immunopathogenesis and control of infections caused by Leishmania parasites. By performing experiments with primary human cells vitro, we demonstrate expression IL-32 isoforms dependent on time exposed L. amazonensis braziliensis antigens. Moreover, for first show functional consequences three different genetic variations IL32 (rs4786370, rs4349147, rs1555001) modulating IL-32γ expression,...

Visceral leishmaniasis (VL) is a chronic parasitic disease caused by Leishmania infantum in the Americas. During VL, several proinflammatory cytokines are produced spleen, liver, and bone marrow. However, role of interleukin-32 (IL-32) has not been explored this disease. IL-32 can induce production innate immune cells polarize adaptive response. Herein, we discovered that L. antigens induced expression mRNA mainly for IL-32γ isoform but also low levels IL-32β transcript human peripheral...

Abstract Objective to report clinical and pathological features of patients with colorectal cancer diagnosed during emergency abdominal surgery. Methods records 107 operated between 2006 2010 were reviewed. Results there 58 women 49 men mean age 59.8 years. The most frequent symptoms were: pain (97.2%), no bowel movements (81.3%), vomiting (76.6%), anorexia (40.2%). Patients divided into five groups: obstructive acute abdomen (n = 68), perforation 21), inflammation 13), sepsis 3), severe...

SUMMARY Primary osteosarcoma of the breast (POB) is an extremely rare and aggressive tumor. Differential diagnosis POB includes chest wall metaplastic carcinoma. Imaging tests that exclude existence a direct connection between tumor wall, as well histopathological immunohistochemical studies rule out presence epithelial component are required for POB. We report case 69-year old woman with pathological findings presented. Therapeutic approach discussed in light current knowledge, including...
