Synthetic oligodeoxynucleotides containing unmethylated CpG motifs (CpG ODNs) stimulate immune cells via Toll-like receptor 9 (TLR9). Because oligodeoxynucleotides (ODNs) are susceptible to gastric degradation, clinical trials designed to evaluate their therapeutic utility have relied solely on parenteral routes of administration. A strategy to improve the activity of orally delivered ODNs by reducing their susceptibility to gastrointestinal (GI) digestion via encapsulation in calcium carbonate nanoparticles (ODNcaps) was recently described...

Clara Lawler, Philip G Stevenson
Murid Herpesvirus-4 (MuHV-4) is a B cell-tropic gamma-herpesvirus that can be studied in vivo Despite viral evasion, type 1 interferons (IFN-I) limit its spread. After MuHV-4 inoculation into footpads, IFN-I protect lymph node subcapsular sinus macrophages (SSM) against productive infection; after peritoneal inoculation, they protect splenic marginal zone macrophages; and they limit MuHV-4 replication in the lungs. While invasive infections can test specific aspects of host colonization, it is important also to understand natural infection...

An 18-year-old male castrated jaguar (Panthera onca) was presented with anorexia and continuous bleeding from the oral cavity after a history of fighting with the partner animal. Clinical evaluation revealed ulcerating lesions on the gingiva and hard palate and a hematoma on the tongue. Computed tomography of the head and endoscopic examination of the esophagus and stomach were unremarkable. Hematology and clinical chemistry revealed severe nonregenerative anemia, mild thrombocytopenia, and moderate azotemia...

Indeterminate dendritic cell neoplasm (IDCN) is an exceedingly rare and mostly cutaneous histiocytosis, frequently associated with other hematopoietic malignancies. We report 2 cases of multilesional cutaneous IDCN. A 55-year-old male with no associated malignancy and complete response to ultraviolet light therapy; and a 72-year-old male with chronic myelomonocytic leukemia (CMML). Both cases showed histiocytoid cytology, positivity for CD1a and no expression of Langerin or BRAF(V600E) . With our patients, the literature describes 79 cases of IDCNs, including 65 (82%) with only skin involvement, 7 cases (9%) with involvement of skin and a second site, 5 cases (6%) involving lymph nodes only, 1 splenic lesion and 1 systemic disease...

BACKGROUND: The metastasis of malignant tumors to the spleen is rare, and only a small percentage of cases can be treated surgically, as splenic metastases generally occur in the context of multivisceral metastatic cancer at a terminal stage. We report a rare case of metachronous solitary splenic metastasis arising from early gastric cancer. CASE PRESENTATION: A 75-year-old man was initially referred to our hospital for examination of gastric cancer, diagnosed at a medical check-up...

BACKGROUND: Porcine reproductive and respiratory syndrome virus (PRRSV) is an important pathogen in pig that causes tremendous economic loss in the global swine industry. PRRSV is divided into the European and North American genotypes, with virulence ranging from apathogenic-moderately virulent to highly pathogenic. The emergence of new highly virulent type 1 strains and coexistence of the two genotypes complicate the differential diagnosis, disease prevention, and control of PRRSV. Although the emergence of a novel type 1 PRRSV strain in mainland China was first confirmed in 2011, there is no information available concerning the pathogenesis of this strain...

BACKGROUND: The surgical approach for adenocarcinoma of the esophagogastric junction (AEJ) still is controversial despite revised tumor-node-metastasis (TNM) classification. This study aimed to evaluate the oncologic outcome of a routine transhiatal approach for AEJ in terms of recurrence and lymph node (LN) metastasis of AEJ. METHODS: Recurrence patterns and LN metastasis of a single, primary AEJ (n = 463) treated by a surgical resection using a transhiatal approach without routine complete mediastinal LN dissection or routine splenectomy were analyzed respectively...

A 73-year-old man presented with fatigue and weight loss. He had CT-proven splenic mass with fistulous connection to the greater curvature of the stomach, which suggested abscess. FDG PET/CT confirmed gastrosplenic fistula in addition to active lymph nodes in the gastrohepatic ligament and epigastric region. Pathological examination after the biopsy of the spleen was consistent with diffuse large B-cell lymphoma. Chemotherapy was administered with close clinical follow-up and resulted in the resolution of fistula without requirement for surgery...

We herein report a rare case of solitary splenic metastasis of a pulmonary carcinoid, for which hand-assisted laparoscopic splenectomy was performed. A 73-year-old man was admitted to the Inoue Hospital (Fukuyama, Japan) in March 2015 with an abnormal shadow of the spleen. The patient had a history of right upper lobectomy with lymph node dissection for a pulmonary typical carcinoid (pT1N0M0 stage IA) 7 years earlier. Plain abdominal computed tomography (CT) revealed a low-density area in the spleen. Enhanced abdominal CT revealed a mass in the spleen measuring 3×3 cm...

OBJECTIVES: To describe the CT findings in a population of dogs with multi-centric lymphoma that involved the spleen and liver. MATERIALS AND METHODS: Clinical records between January 2008 and June 2015 were reviewed. Thoracic and abdominal CT examinations of patients diagnosed with multi-centric lymphoma were evaluated by a board-certified radiologist. A diagnosis of multi-centric lymphoma with splenic and hepatic involvement was based upon cytological identification and immunophenotyping of neoplastic lymphocytes in cellular samples harvested from a peripheral lymph node, the spleen and the liver...

The bioavailability of glucocorticoids is modulated by enzyme 11β-hydroxysteroid dehydrogenase type 1 (11HSD1), which catalyzes the conversion of inactive 11-oxo-glucocorticoids to active 11-hydroxy-glucocorticoids cortisol and corticosterone and is regulated by pro-inflammatory cytokines. Our aim was to assess the effect of colitis on the expression of 11HSD1 in specific microanatomical compartments of the mucosal immune system. Using qRT-PCR we quantified the expression of 11HSD1 and cytokines in the colon, mesenteric lymph nodes (MLN) and spleen of mice with colitis...

BACKGROUND: With the introduction of complete mesocolic excision (CME) and the application of laparoscopic technique, surgery for colon cancer has become more standardized and the curative effect has improved [1]. The key points in laparoscopic right hemicolectomy are high ligation of main vessels and root dissection of lymph nodes. The wide range of variations in vascular architecture and intraoperative bleeding are common causes of prolonged surgical time, wound hemorrhage, and even transfer to the opening operation...

BACKGROUND: In radical operations for gastric cancer, a balance between the quality of lymph node dissection and safety of surgery must be ensured. During suprapancreatic lymphadenectomy in laparoscopic gastrectomy (LG), an adequate operative field should be safely and effectively established to reduce pancreas-related complications. We present a novel approach that avoids direct compression of the pancreas in LG and describe the surgical outcomes of this method. METHODS: We historically compressed the pancreas during suprapancreatic lymph node dissection in LG to obtain an adequate operative field but have since modified our operative technique...

T cells play a critical role in host defense against intestinal bacteria. We have shown that ethanol combined with burn injury suppresses Peyer's patch (PP) Th17 cytokines 1 d after injury. We assessed the mechanism of suppressed Th17 effector functions. Mice were gavaged with ethanol 4 h before burn injury and euthanized 1, 3, and 7 d after injury. Mesenteric lymph nodes (MLNs), PPs, and spleen Th1 and Th17 cytokines were assessed. A significant decrease in IL-17, IL-22, IL-2, and IFN-γ were observed in all 3 lymphoid organs 1 and 3 d after injury...

BACKGROUND: Impact of splenic hilar LN dissection during total gastrectomy for proximal advanced gastric cancer is controversial. The objective of this study was to assess the impact on prognosis of splenic hilar lymph node(LN) metastasis compared to that of metastasis to other regional LN groups. STUDY DESIGN: Patients who underwent total gastrectomy with D2 LN dissection from 2000 to 2010 were reviewed retrospectively. The clinicopathologic characteristics and long-term results of patients with splenic hilar LN metastasis were compared to those of patients with only metastasis to other extraperigastric LNs (stations #8a, #9, #11, or #12a)...

Sarcoidosis is a systemic granulomatous disease of unknown aetiology, which is characterized by bilateral hilar lymphadenopathy and pulmonary disease. Clinically detected cardiac involvement occurs in 5% of sarcoid patients, although cardiac manifestations are discovered in 25% of the cases at autopsy. Sarcoid heart disease frequently causes atrioventricular block. The authors present the case of a 44-year-old man with bradycardia. On admission, second degree Mobitz II, then third degree atrioventricular block was diagnosed...
