Venous invasion (VI) is an independent predictor of hematogenous metastasis and mortality in colorectal cancer (CRC), yet remains widely under-reported. Its detection may require recognition of subtle morphologic clues which at times are only unmasked with an elastin stain. This study evaluates the impact of a knowledge transfer initiative (KTI) on VI detection in a "real world" pathology practice setting. Following participation in an interobserver variability study of VI detection (Kirsch et al 2013), twelve participants received educational materials highlighting key issues in VI detection...

Helminth infections have the ability to modulate host's immune response through mechanisms that allow the chronic persistence of the worms in the host. Here, we investigated the mechanisms involved on the suppressive effect of Ascaris suum infection using a murine experimental model of LPS-induced inflammation. We found that infection with A. suum markedly inhibited leukocyte influx induced by LPS into air pouches, suppressed secretion of pro-inflammatory cytokines (IL-1β, TNF-α and IL-6) and induced high levels of IL-10 and TGF-β...

Secondary lymphedema of the upper and lower extremities related to prior oncologic therapies, including cancer surgeries, radiation therapy, and chemotherapy, is a major cause of long-term morbidity in cancer patients. For the upper extremities, it is most commonly associated with prior oncologic therapies for breast cancer, while for the lower extremities, it is most commonly associated with oncologic therapies for gynecologic cancers, urologic cancers, melanoma, and lymphoma. Both non-surgical and surgical management strategies have been developed and utilized, with the primary goal of all management strategies being volume reduction of the affected extremity, improvement in patient symptomology, and the reduction/elimination of resultant extremity-related morbidities, including recurrent infections...

BACKGROUND: Central collection of tissue blocks for pathological and translational research is particularly important in rare diseases. Transfer of tissue blocks from primary to central pathology is of crucial importance. OBJECTIVES: We aimed to answer the following questions: Has the transfer of tissue blocks sent for consultation or within clinical trials changed over the last 20 years? What are the reasons for reclaiming tissue blocks by the primary pathology and what actions would convince primary pathologists to leave the blocks in the reference pathology? MATERIAL AND METHODS: The first 100 biopsies of each year between 1995 and 2015 (n = 2100), as well as all tissue transfers within therapeutic studies (n = 1405, German Hodgkin Study Group, GHSG) between 1998 and 2015, were analyzed separately for block reclaims using the Department of Pathology database...

Type 1 diabetes (T1D) results from autoimmune destruction of insulin-producing pancreatic β cells. Therapies need to incorporate strategies to overcome the genetic defects that impair induction or maintenance of peripheral T-cell tolerance and contribute to disease development. We tested whether the enforced expression of an islet autoantigen in antigen-presenting cells (APC) counteracted peripheral T-cell tolerance defects in autoimmune-prone NOD mice. We observed that insulin-specific CD8(+) T cells transferred to mice in which proinsulin was transgenically expressed in APCs underwent several rounds of division and the majority were deleted...

PROBLEM: To evaluate the role of regulatory T (Treg) cells in autoimmune ovarian disease (AOD). METHOD OF STUDY: AOD model was set up by thymectomy of BALB/C mice on day 3 (d3tx). The variation of T lymphocyte subsets, especially the Treg cells were analyzed in the peripheral blood, spleen, para-aortic, and inguinal lymph nodes in d3tx mice. The effect of Treg cells on AOD was further evaluated by adoptive transfer of Treg cells into d3tx mice (d3tx+Treg). RESULTS: In d3tx mice, the ratio of Treg/CD4(+) was significantly increased rapidly from 1st to 2nd week, rapidly declined in 3rd week, then decreased slowly until the 9th week...

BACKGROUND: Atopic dermatitis (AD) is a common inflammatory skin disease with dysfunction of the skin barrier, an abnormal immune response and frequent allergies to environmental antigens like food antigens. Clinical observations suggest that certain diets can influence the course of AD. OBJECTIVE: Here we compared the phenotype of food allergen-specific T cells activated through skin or gut allergen exposure to transfer skin inflammation into naïve recipients upon epicutaenous allergen challenge...

Dendritic cells (DCs), a bridge of innate and adaptive immune responses, play a key role in the development of multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), an animal model for MS. Administration of tolerogenic DCs has been used as an immunotherapy in the autoimmune diseases. Deficiency of vitamin D is an environmental risk factor of MS. In this study, we induced tolerogenic DCs by 1,25-dihydroxyvitamin D3 (1,25(OH)2 D3 ) and adoptive transferred the tolerogenic DCs (VD3-DCs) into EAE mice...

Skin sensitization is one of the key safety endpoints for chemicals applied directly to the skin. Several integrated testing strategies (ITS) using multiple non-animal test methods have been developed to accurately evaluate the sensitizing potential of chemicals, but there is no regulatory-accepted ITS to classify a chemical as a non-sensitizer. In this study, the predictive performance of a binary test battery with KeratinoSens™ and h-CLAT compared to the local lymph node assay (LLNA) and human data was examined using comprehensive dataset of 203 chemicals...

T-helper 2 (Th2) cell responses defend against parasites. Although dendritic cells (DCs) are vital for the induction of T-cell responses, the DC subpopulations that induce Th2 cells in the intestine are unidentified. Here we show that intestinal Th2 responses against Trichuris muris worms and Schistosoma mansoni eggs do not develop in mice with IRF-4-deficient DCs (IRF-4(f/f) CD11c-cre). Adoptive transfer of conventional DCs, in particular CD11b-expressing DCs from the intestine, is sufficient to prime S. mansoni-specific Th2 responses...

OBJECTIVE: This study investigated the outcome of lymphedema microsurgery with or without microsurgical breast reconstruction for breast cancer-related lymphedema (BCRL). BACKGROUND: Complete decongestive therapy, lymphovenous anastomosis, and vascularized lymph node flap transfer are the 3 major treatment modalities for BCRL. Releasing axillary contracture and transferring a free flap may potentially improve the BCRL. METHODS: Between 2004 and 2015, 124 patients with BCRL who underwent 3 treatment modalities without or with microsurgical breast reconstruction were included in this study as groups I and II, respectively...

Vascularized lymph node transfers have multiple donor sites with risk of iatrogenic lymphedema. We sought to describe in detail a surgical technique that is safe, reproducible, and efficient in harvesting gastroepiploic vascularized lymph nodes using real-time indocyanine green (ICG) fluorescent imaging. Photographs and video were acquired from a case to depict a step-by-step approach. ICG was endoscopically injected into the submucosa of the greater curvature of the stomach at the outset of the procedure. A laparoscopic harvest of the gastroepiploic vascular pedicle and lymph nodes ensued with the assistance of fluorescent imaging...

Vascularized lymph node (VLN) transfer has been of high interest in the past decade for the treatment of lymphedema, since it has been shown to be effective in reducing limb volumes, decreasing infectious episodes and improving quality of life. Multiple donor sites have been described in the quest for the optimal one. Herein, we describe a novel lymph node flap option based on the ileocolic artery and vein. The ileocecal vascularized lymph node (IC-VLN) flap was used in the management of a 33-year-old male patient with lower extremity lymphedema secondary to left inguinal trauma...

INTRODUCTION: A growing number of surgeons perform lymph node transfers for the treatment of lymphedema. When harvesting a vascularized lymph node groin flap (VGLNF) one of the major concerns is the potential risk of iatrogenic lymphedema of the donor-site. This article helps understanding of the lymph node distribution of the groin in order to minimize this risk. MATERIALS AND METHODS: Fifty consecutive patients undergoing abdominal mapping by multi-detector CT scanner were included and 100 groins analyzed...

Th1 and Th17 cells have an established role in protective immunity to Bordetella pertussis, but this evidence is based largely on peripheral T cells. There is emerging evidence that local tissue-resident memory T (TRM) cells that accumulate in tissue following mucosal infection may be crucial for long-term immunity. In this study, we examined the role of respiratory CD4 TRM cells in immunity to B. pertussis Natural immunity to B. pertussis induced by infection is considered long lasting and effective at preventing reinfection...
