A novel virus, rainbow trout orthomyxovirus (RbtOV), was isolated in 1997 and again in 2000 from commercially-reared rainbow trout (Oncorhynchus mykiss) in Idaho, USA. The virus grew optimally in the CHSE-214 cell line at 15°C producing a diffuse cytopathic effect; however, juvenile rainbow trout exposed to cell culture-grown virus showed no mortality or gross pathology. Electron microscopy of preparations from infected cell cultures revealed the presence of typical orthomyxovirus particles. The complete genome of RbtOV is comprised of eight linear segments of single-stranded, negative-sense RNA having highly conserved 5' and 3'-terminal nucleotide sequences...

In 1849, the Irish Professor of Surgery, Sir Robert William Smith, by publishing his "Treatise on the Pathology, Diagnosis and Treatment of Neuroma", collected six previous examples of "general development of neuromatous tumours" and reported three further cases (two personal and one referred) of what is nowadays known as neurofibromatosis. Among these latter cases, there was a 35-year-old cattle-driver, John McCann, who was first admitted at hospital in 1840 because of a large tumour on the right side of his neck thought to be malignant (and a second tumour sublingually) but not operated...

AIM: Lymph node yield (LNY) is a valid marker of prognosis in oral cancer. Precise estimation of LNY in Indian patients with T3/T4 gingivobuccal sulcus squamous cell carcinoma (GBS-SCC) has not been well documented. Hence, the primary objective of the study was to determine the LNY in patients with T3/T4 SCC of mandibular GBS, and the secondary objective was to study the association of LNY with clinicopathological factors such as tumor thickness, histological differentiation, number of positive nodes, and extracapsular spread (ECS)...

Histomonas meleagridis is a flagellate protozoan organism that can cause severe necrotizing typhlitis and hepatitis in gallinaceous birds. Peafowl ( Pavo spp.) have been shown to be susceptible to histomoniasis in experimental settings, but there are few reports of natural histomoniasis in this species. A retrospective study of the archived cases at 2 veterinary diagnostic laboratories in the United States yielded 5 cases of peafowl with gross and histologic findings characteristic of histomoniasis. Lesions included bilateral, transmural fibrinonecrotic typhlitis and multifocal necrotizing hepatitis with associated trophozoites morphologically consistent with H...

Mycoplasma hyosynoviae causes arthritis in pigs older than 12 weeks. The role of colostrum in protection of piglets against M. hyosynoviae infection is not clear. Our objective was therefore to investigate whether transfer of maternal immunity to piglets was involved in early protection against the infection. Experimental infections were carried out in three groups of weaners receiving different levels of M. hyosynoviae-specific colostrum components; Group NC derived from Mycoplasma free sows and possessed no specific immunity to M...

Adrenal lesions are routinely encountered incidentally in clinical practice. Although most of these lesions are benign, malignancy needs to be excluded. Therefore, the initial clinical workup is to exclude aggressive characteristics suggesting malignancy and to identify characteristics predictive of the most common benign lesion, an adrenal adenoma. Predicting a benign adenoma using a variety of imaging modalities has been widely studied using unenhanced computed tomography (CT), contrast enhanced CT, and magnetic resonance (MR) imaging...

Bowel inflammation is closely linked to chronic joint inflammation. Research reported in the 1980s demonstrated bowel inflammation with gross and microscopic pathological features identical to those of Crohn's disease in over 60% of patients with spondyloarthritis (SpA). Numerous prospective studies have evidenced joint involvement in patients with chronic inflammatory bowel disease (CIBD) and bowel inflammation in patients with SpA. Nevertheless, the interactions of joint disease and chronic bowel inflammation remain incompletely elucidated...

E Rene Rodriguez, Carmela D Tan
The normal gross anatomy and light microscopy of the human pericardium is presented in detail that allows easy correlation with current cardiac imaging modalities. The anatomical structures of the parietal pericardium are shown from its mediastinal surface, including its ligaments to the sternum diaphragm and vertebral column. The attachments of the parietal pericardium to the great vessels showing the intrapericardial location of the root of the aorta and pulmonary artery are documented. Also the attachments of the parietal pericardium to the venae cavae and the pulmonary veins are illustrated in detail...

BACKGROUND: Breast surgeons have a wide variety of intraoperative techniques available to help achieve low rates for positive margins of excision, with variable levels of evidence. METHODS: A systematic review of the medical literature from 1995 to July 2016 was conducted, with 434 abstracts identified and evaluated. The analysis included 106 papers focused on intraoperative management of breast cancer margins and contained actionable data. RESULTS: Ultrasound-guided lumpectomy for palpable tumors, as an alternative to palpation guidance, can lower positive margin rates, but the effect when used as an alternative to wire localization (WL) for nonpalpable tumors is less certain...

BACKGROUND: Thyroid-related mortality has remained constant despite increasing incidence of thyroid carcinoma. Most thyroid nodules are benign, therefore, ultrasound and fine needle aspiration (FNA) are integral in cancer screening. We hypothesize that increased nodule size at ultrasound does not predict malignancy and correlation between nodule size at ultrasound and pathologic exam is good. METHODS: Resected thyroids with preoperative ultrasounds were identified...

PURPOSE: Stereotactic body radiation therapy (SBRT) may be used to increase surgery candidacy in borderline resectable (BRPC) and locally advanced (LAPC) pancreatic cancer. However, the planning target volume (PTV) may need to be limited to avoid toxicity when the gross tumor volume (GTV) is anatomically involved with surrounding critical structures. Our study aims to characterize the coverage of GTV and investigate the association between modified PTV and pathologic (pCR) or near pathologic (npCR) complete response rates determined from the surgical specimen...

PURPOSE: Diffusion weighted MRI (DWI) is a promising imaging technique for early prediction of tumor response to radiation therapy. A recently proposed longitudinal DWI strategy using a Co-60 MRI guided RT system (MRIgRT) may bring functional MRI guided adaptive radiation therapy closer to clinical utility. We report our preliminary results of using this longitudinal DWI approach performed on the MRIgRT system for predicting the response of sarcoma patient to preop RT. METHODS: Three sarcoma patients who underwent fractionated IMRT were recruited in this study...
