Papillary thyroid carcinoma (PTC) is a common malignancy with multiple variants, some of which are rarely encountered in routine surgical pathology practice. PTC with exuberant nodular fasciitis-like stroma or PTC with fibromatosis-like stroma is one such variant. This tumor is characterized by an abundant stromal component with an intervening epithelial component with the typical morphologic features of PTC. We describe gross and histopathological features of this rare variant of papillary carcinoma in a 38-year-old female and review the literature...

BACKGROUND/AIMS: Gangliogliomas (GGs) are rare central nervous system tumors occurring primarily in the supratentorial compartment with infratentorial instances most often involving the brain stem. Infratentorial GGs typically present with signs and symptoms of increased intracranial pressure (ICP), cranial nerve deficits, or focal cerebellar findings; rarely, these tumors have been associated with focal seizures. METHODS: In this report, we describe an atypical presentation of a cerebellar GG in a 20-month-old male who initially presented with syncope and emesis in the absence of electrographic evidence of seizures, radiographic evidence of hydrocephalus, or elevated ICP...

A four-year-old female was admitted to a university-based children's hospital with a newly-diagnosed posterior fossa tumor. She was started on famotidine and high-dose dexamethasone and underwent gross total resection of a medulloblastoma. She was continued on dexamethasone and famotidine. She exhibited postoperative posterior fossa syndrome and was started on enteral feeds via the nasoduodenal tube. She had small gastrointestinal bleeds on postoperative days eight, 11, and 18, and was found to have a well-circumscribed posterior duodenal ulcer...

Although optogenetic techniques have proven to be invaluable for manipulating and understanding complex neural dynamics over the past decade, they still face practical and translational challenges in targeting networks involving multiple, large, or difficult-to-illuminate areas of the brain. We utilized inhibitory luminopsins to simultaneously inhibit multiple limbic structures of the rat brain in a hardware-independent and cell-type specific manner to suppress seizure activity in a rat model of epilepsy. In addition to elucidating mechanisms of seizure suppression never directly demonstrated before, this work also illustrates how precise multi-focal control of pathological circuits can be advantageous for the treatment of epilepsy, which may also be applicable to the treatment and understanding of other neurological disorders involving broad neural circuits...

Between 2006 and 2015, a high incidence of dilated cardiomyopathy (DCM) was diagnosed in a captive population of banded mongooses (Mungos mungo) at Chester Zoo, United Kingdom. The aim of this study was to characterize DCM in these mongooses in order to raise awareness of this condition and help inform management and clinical decisions. Prospective clinical assessments, including echocardiography, radiography, and cardiac biomarkers, were carried out in four mongooses remaining in the collection. Radiographs from 15 mature mongooses were reviewed and cardiac size and metrics assessed...

Surgical-site infection (SSI) is a common postoperative complication, primarily caused by Staphylococcus aureus. S aureus produces hyaluronidase which degrades hyaluronic acid (HA). HA prevents bacterial proliferation and has anti-inflammatory effects to promote wound healing. We evaluated the effect of HA injection with systemic antibiotics for prevention and treatment of SSIs caused by S aureus. An open wound was created on the dorsum of 40 rats. The wound bed was sutured with S aureus inoculated thread. The test group was injected with HA (HA group), and the control group received a subcutaneous injection of normal saline (NS group)...

Rationale: Cortical bone stem cells (CBSCs) have been shown to reduce ventricular remodeling and improve cardiac function in a murine myocardial infarction (MI) model. These effects were superior to other stem cell types that have been used in recent early stage clinical trials. However, CBSC efficacy has not been tested in a preclinical large animal model using approaches that could be applied to patients. Objective: To determine if post-MI transendocardial injection of allogeneic CBSCs reduces pathological structural and functional remodeling and prevents the development of heart failure in a swine MI model...

Gudrun Overesch, Peter Kuhnert
Enzootic pneumonia (EP) in pigs caused by Mycoplasma (M.) hyopneumoniae has successfully been combatted in Switzerland. A control program was fully implemented in 2004 which is based on total depopulation strategies of affected fattening farms as well as partial depopulation on breeding farms. Thereby, the number of cases has dropped drastically from more than 200 in 2003 to two cases in 2013. Currently monitoring is done based on clinical observation and subsequent diagnostic of coughing pigs. Moreover, in case of more than 10% gross pathological lesions per slaughter batch laboratory confirmation for EP is compulsory...

BACKGROUND: Tumors invading both the anterior skull base and the sinonasal area have been traditionally accessed via largely invasive open craniofacial approaches. Minimally invasive extended endoscopic endonasal approaches have recently become increasingly available, but have anatomical limitations and require incremental experience and thus high patient volume. Our objective was to assess the applicability of a novel combination of the minimally invasive supraciliary incision and the limited maxillofacial osteotomy as a combined surgical approach for large tumors invading both the anterior skull base and the sinonasal area...

Toxoplasma gondii is a zoonotic parasite found in vertebrates worldwide for which felids serve as definitive hosts. Despite low densities of felids in northern Canada, Inuit people in some regions show unexpectedly high levels of exposure, possibly through handling and consumption of Arctic wildlife. Free-ranging caribou (Rangifer tarandus) are widely harvested for food across the Canadian North, show evidence of seroexposure to T. gondii, and are currently declining in numbers throughout the Arctic. We experimentally infected three captive reindeer (conspecific with caribou) with 1000, 5000 or 10,000 oocysts of T...

BACKGROUND: Although the use of a standardized, synoptic pathology report for breast cancer has been demonstrated to improve the quality of reports, the role of a standardized form for the submission of breast cancer excision specimens to the histopathology laboratory has not yet, to our knowledge, been investigated. METHOD: The proforma for oncological breast excisions was devised collaboratively between the pathologists and the surgeons. During the month prior to the introduction of the proforma, and in the three-and-a-half months following the form's rollout, the senior pathology registrar at the CMJAH grossing bench completed an audit form for each breast cancer excision from HJH...
