An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

INTRODUCTION: A large heterogeneous group of unproven remedies exist to treat cancer in both developed and developing countries. Some of these remedies often do more harm than good to the patients. The traditional medicine is the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures. The traditional medicine in Oman is based on herbal treatment and skin treatment (massage, Cupping and skin burn "cautery" treatment-known as Wasam or Kaiy)...

BACKGROUND: Castleman's disease (CD) is an uncommon, heterogeneous lympho-proliferative disorder leading to high circulating levels of interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF). Renal involvement has been only described in a limited number of small studies. Herein, we report a rare case of renal thrombotic microangiopathy (TMA) associated with CD and investigate the podocyte expression of VEGF in the renal biopsy prior to initiation of treatment. CASE PRESENTATION: An 18-year-old male presented with fever, diarrhea, diffuse lymphadenopathy, ascites and acute kidney injury...

Rationale: Lymphatic vessel formation and function constitutes a physiologically and pathophysiologically important process, but its genetic control is not well understood. Objective: Here, we identify the secreted Polydom/Svep1 protein as essential for formation of the lymphatic vasculature. We analyzed mutants in mice and zebrafish to gain insight into the role of Polydom/Svep1 in the lymphangiogenic process. Methods and Results: Phenotypic analysis of zebrafish polydom/svep1 mutants showed a decrease in venous and lympho-venous sprouting, which leads to an increased number of intersegmental arteries...

Astaxanthin, a carotenoid found mainly in seafood, has potential clinical applications due to its antioxidant activity. In this study, we evaluated the effect of dietary astaxanthin derived from Haematococcus pluvialis on skin photoaging in UVA-irradiated hairless mice by assessing various parameters of photoaging. After chronic ultraviolet A (UVA) exposure, a significant increase in transepidermal water loss (TEWL) and wrinkle formation in the dorsal skin caused by UVA was observed, and dietary astaxanthin significantly suppressed these photoaging features...

Hyperferritinemia (>10,000 ng/ml) is an important hallmark used as an indicator of infection triggered macrophage activation syndrome leading to hemophagocytic lympho histiocytosis (HLH). Measurement of serum ferritin can be used in diagnosis as well as disease monitoring indicator and prognosis related to HLH, cAPS, sepsis, neoplasm and inflammatory conditions. It is a major contributor to manage critically ill patients as predicting and monitoring indicator. It can be used as acute phase response in conditions of MAS, AOSD, cAPS etc...

INTRODUCTION: Skeletal tuberculosis involving the small bones is less common than pulmonary tuberculosis. Tuberculous dactylitis involves the short tubular bones of the hands and feet more commonly in children. The bones of the hands are the one's more frequently affected than bones of the feet, with the proximal phalanx of the index and middle fingers as the commonest sites for infection. Spread to the skeletal system occurs during the initial infection via the lympho-haematogenous route...

The lymphoid-myeloid transdifferentiation potentials of members of the C/EBP family (C/EBPα, β, δ, and ε) were compared in v-Abl-immortalized primary B cells. Conversion of B cells to macrophages was readily induced by the ectopic expression of any C/EBP, and enhanced by endogenous C/EBPα and β activation. High transgene expression of C/EBPβ or C/EBPε, but not of C/EBPα or C/EBPδ, also induced the formation of granulocytes. Granulocytes and macrophages emerged in a mutually exclusive manner. C/EBPβ-expressing B cells produced granulocyte-macrophage progenitor (GMP)-like progenitors when subjected to selective pressure to eliminate lymphoid cells...

INTRODUCTION: Recently, it has been shown that hematological parameters may be used as markers of inflammatory response. In this study, the authors aimed to identify the potential roles of the neutrophil-lymphocyte ratio (NLR) and other hematological markers in the evaluation of hidradenitis suppurativa (HS), a chronic, recurrent inflammatory disease. MATERIALS AND METHODS: A total of 35 patients, diagnosed with HS between January 1, 2012 and December 31, 2014, were categorized into 3 groups according to the Hurley staging system...

Despite substantial experimental and epidemiological research, there is limited knowledge of the uranium-induce health effects after chronic low-dose exposures in humans. Biological markers can objectively characterize pathological processes or environmental responses to uranium and confounding agents. The integration of such biological markers into a molecular epidemiological study would be a useful approach to improve and refine estimations of uranium-induced health risks. To initiate such a study, Concerted Uranium Research in Europe (CURE) was established, and involves biologists, epidemiologists and dosimetrists...

Pilosebaceous unit occlusion and secondary inflammatory perifollicular lympho-histiocytic infiltration seem to be the underlying etiopathogenic mechanisms giving rise to hidradenitis suppurativa (HS). Increased levels of tumor necrosis factor (TNF)-alpha and other cytokines such as interleukins 12 and 23 (IL12/23) and interleukins 10 and 17 have been observed in HS lesional skin. Biological drugs have been reported to be effective for HS, but the level and duration of the response are quite variable. Among anti-TNF drugs, adalimumab and infliximab are the drugs that seem to obtain better results in HS...

Posttransplant lymphoproliferative disorders are a spectrum of lymphoproliferative disorders seen in recipients of solid-organ, bone marrow, and stem cell allografts. They include polyclonal early lesions mimicking infectious mononucleosis and monoclonal proliferations of B and T cells, indistinguishable from lymphomas occurring in immunocompetent individuals. Although most posttransplant lymphoproliferative disorders are B-cell neoplasms, T-cell posttransplant lymphoproliferative disorders are very rare. Among solid-organ transplants, renal allografts have low risk for development of posttransplant lymphoproliferative disorders...

The alkylating agent melphalan is used in the treatment of hematological malignancies, especially multiple myeloma. In the past, the usefulness of melphalan has been solely attributed to its cytotoxicity on fastgrowing cancerous cells. Although the immunomodulatory effects of melphalan were suggested many years ago, only recently has this aspect of melphalan's activity begun to be elucidated at the molecular level. Emerging evidence indicates that melphalan can foster an immunogenic microenvironment by inducing immunogenic cell death (ICD) as characterized by membrane translocation of endoplasmic reticulum protein calreticulin (CRT) and by release of chromatin-binding protein high-mobility group box 1 (HMGB1)...

Chronic lipopolysaccharide (LPS) exposure to mice reduces the lymphoid compartment and skews the hematopoietic cell compartment toward myeloid-cells, which is considered to be a direct effect of LPS on hematopoietic stem cells. However, the effect of chronic LPS exposure on stromal-cells, which compose the hematopoietic microenvironment, has not been elucidated. Here, we investigated early- and late-phase effects of repeated LPS exposure on stromal-cells. During the early phase, when mice were treated with 5 or 25 µg LPS three times at weekly intervals, the numbers of myeloid-progenitor (colony forming unit-granulocyte macrophage (CFU-GM)) cells and B lymphoid-progenitor (CFU-preB) cells in the bone-marrow (BM) rapidly decreased after each treatment...

We studied acute myeloid leukemia (AML) patients with lympho-myeloid clonal hematopoiesis (LM-CH), defined by the presence of DNA methyltransferase 3A (DNMT3A) mutations in both the myeloid and lymphoid T-cell compartment. Diagnostic, complete remission (CR) and relapse samples were sequenced for 34 leukemia-related genes in 171 DNMT3A mutated adult AML patients. AML with LM-CH was found in 40 patients (23%) and was associated with clonal hematopoiesis of indeterminate potential years before AML, older age, secondary AML and more frequent MDS-type co-mutations (TET2, RUNX1 and EZH2)...

The survival rates of gastric cancer patients with cytology-positive peritoneal lavage fluid without macroscopic dissemination (CY+/P-) is the same as that of patients with overt peritoneal metastasis.The 5-year survival rate of such patients is only 2%. The current study aims to highlight its significance in the staging of gastrointestinal malignancies and its implications for patient care. Prospective nonrandom analysis of peritoneal wash cytology in patients with gastrointestinal malignancies was conducted in the department of Surgical Gastroenterology, Nizams Institute of Medical Sciences, Hyderabad from January 2012 to June 2013...
