An imported crossbred Angus beef steer aged eight to twelve months died suddenly on the eighth day of a quarantine period in Japan. Gross examination showed the peritoneum and mesentery consisted of numerous nodules of various sizes. Histological examination revealed chronic suppurative granulomatous peritonitis with eosinophilic rosettes surrounding colonies of Gram-negative bacilli. The bacteria isolated from the nodules were confirmed to be Actinobacillus lignieresii based on the results of 16S rRNA gene sequencing and immunohistochemistry...

Gallibacterium anatis causes infections in the reproductive tract of egg-laying hens and induce increased mortality and decreased egg production. New prophylactic measures are needed in order to improve animal welfare and production efficiency. Bacterial outer membrane vesicles (OMVs) have previously shown promising results in protection against infections and we hypothesized that OMVs could serve as an immunogen to protect egg-laying hens against G. anatis. To investigate the immunogenic potential of G. anatis OMVs, two in vivo studies in egg-laying hens were made...

BACKGROUND: Undescended testis is a common problem, which is prevalent in 3 % of male infants. This study aimed to determine the effect of leaving the deep inguinal ring (DIR) without closure during laparoscopic orchiopexy (LO), with regard to post-operative hernia formation and other outcomes. METHODS: From 2012 to 2014, 63 testicular units were managed with laparoscopy for non-palpable testis (NPT). Diagnostic laparoscopy was performed for all NPTs, and when they were intra-abdominal (42 testicular units), the DIR was left open after mobilization of the testis into the scrotum medial to the inferior epigastric vessels (Prentiss manoeuvre)...

BACKGROUND: The canal of Nuck is a fold of peritoneum that invaginates into the inguinal canal and closes at or just before birth. If the canal of Nuck remains open in female infants, herniation of the uterus, adnexa and/or bowel loops may arise through the inguinal canal into the labia majora. CASE REPORT: The present case is a 12-week-old female infant with complaints of left groin swelling and discomfort. Ultrasonographic examination revealed a left inguinal hernia containing both adnexa (ovaries and fallopian tubes), uterus and small bowel loops with fluid...

Chronic inflammatory conditions during peritoneal dialysis (PD)-treatment lead to the impairment of peritoneal tissue integrity. The resulting structural and functional reorganization of the peritoneal membrane diminishes ultrafiltration rate and thereby enhances mortality by limiting dialysis effectiveness over time. Tumour necrosis factor (TNF) and its receptors TNFR1 and TNFR2 are key players during inflammatory processes. To date, the role of TNFR1 in peritoneal tissue damage during PD-treatment is completely undefined...

IFN regulatory factor (IRF)3 plays a detrimental role in the cecal ligation and puncture (CLP) mouse model of sepsis. However, it is unclear which pathway activates IRF3 in this context. In this report we investigate two pathways that activate IRF3: the Stimulator of Interferon Genes (STING) pathway (which senses cytosolic DNA) and the TIR-domain-containing adapter-inducing interferon-β (TRIF) pathway (which sense dsRNA and LPS via Toll-like receptor (TLR) 3 and 4). Initially, we examine the impact of these pathways using a severe CLP model (∼90% mortality)...

Autotaxin (ATX) is a secreted glycoprotein that converts lysophosphatidylcholine (LPC) to the bioactive phospholipid lysophosphatidic acid (LPA) and is the major enzyme generating circulating LPA. Inhibition of LPA signaling has profound anti-fibrotic effects in multiple organ systems including the lung, kidney, skin and peritoneum. However, other LPA-generating pathways exist and the role of ATX in localized tissue LPA production and fibrosis remains unclear and controversial. In this study, we describe the preclinical pharmacological, pharmacokinetic and pharmacodynamic properties of a novel small-molecule ATX inhibitor [3-((6-chloro-2-cyclopropyl-1-(1-ethyl-1H-pyrazol-4-yl)-7-fluoro-1H-indol-3-yl) thio)-2-fluorobenzoic acid sodium salt] (PAT-505)...

Endometriosis is a gynecologic disease affecting up to 10% of the women and a major cause of pain and infertility. It is characterized by the implantation of functional endometrial tissue at ectopic positions generally within the peritoneum. This complex disease has an important genetic component with a heritability estimated at around 50%. This review aims at providing recent insights into the genetic bases of endometriosis, and present a detailed overview of evidence of epigenetic alterations specific to this disease...

Dog bites are a major cause of injury, especially in the pediatric population. Common anatomic sites of dog bites on children are the peripheries and the head and neck. The torso is reportedly injured less frequently, and only 2 cases of intra-abdominal injury secondary to dog bites have been reported. We recently encountered a 3-year-old boy presenting with peritonitis who had sustained multiple dog bites to his trunk and upper limbs. Emergency laparotomy was performed. Surgical findings revealed penetration of the peritoneum and single perforation of the anterior gastric wall with multiple tooth marks; thus, the gastric perforation was debrided and repaired...

Extrauterine spread of leiomyomas is rare and most commonly occurs in the lungs. We present a case of simultaneous metastatic leiomyomatosis to the lungs and peritoneal cavity following laparoscopic myomectomy with power morcellation. The patient presented to our institution for further management where she underwent a robotically assisted hysterectomy with bilateral salpingo-oophorectomy. Leiomyomatous implants measuring up to 2.4 cm were resected from bowel mesentery and bladder peritoneum. Subsequent serial computed tomography imaging confirmed stable pulmonary nodules without new intraperitoneal lesions...

OBJECTIVE: The majority of advanced ovarian cancer patients have peritoneal carcinomatosis involving from the pelvis to upper abdomen, which is a major obstacle to optimal cytoreduction. Since total parietal peritonectomy was introduced for treating peritoneal carcinomatosis from colorectal cancer [3], similar surgical techniques including pelvic peritonectomy have been applied in advanced ovarian cancer with peritoneal carcinomatosis [1], and these can increase the rate of complete cytoreduction up to 60% [2]...

BACKGROUND:  When treated with the same antibiotic dose, children achieve different 0- to 24-hour area under the concentration-time curves (AUC0-24) because of maturation and between-child physiological variability on drug clearance. Children are also infected by Mycobacterium tuberculosis isolates with different antibiotic minimum inhibitory concentrations (MICs). Thus, each child will achieve different AUC0-24/MIC ratios when treated with the same dose. METHODS:  We used 10 000-subject Monte Carlo experiments to identify the oral doses of linezolid, moxifloxacin, and faropenem that would achieve optimal target exposures associated with optimal efficacy in children with disseminated tuberculosis...

Intra-individual tumoural heterogeneity (ITH) is a hallmark of solid tumours and impedes accurate genomic diagnosis and selection of proper therapy. The purpose of this study was to identify ITH of ovarian high-grade serous carcinomas (OSCs) and to determine the utility of ascitic cancer cells as a resource for mutation profiling in spite of ITH. We performed whole-exome sequencing, copy number profiling, and DNA methylation profiling of four OSC genomes using multiregional biopsy from 13 intra-ovarian lesions, 12 extra-ovarian tumour lesions (omentum/peritoneum), and ascitic cells...

BACKGROUND: Multi-walled carbon nanotubes (MWCNTs) constitute one of the most promising types of nanomaterials in industry today. With their increasing use, the potential toxicity and carcinogenicity of MWCNT needs to be evaluated in bioassay studies using rodents. Since humans are mainly exposed to MWCNT by inhalation, we performed a 104-week carcinogenicity study using whole-body inhalation exposure chambers with a fibrous straight type of MWCNT at concentrations of 0, 0.02, 0.2, and 2 mg/m(3) using male and female F344 rats...
