Pancreatic leiomyosarcoma in a domestic shorthair cat.

Case Summary: A 7-year-old female neutered domestic shorthair cat was presented with weight loss, abdominal distension, lethargy, pyrexia and hyporexia. Haematology and biochemistry were unremarkable. Abdominal ultrasound revealed a cystic mass within the left cranial abdominal quadrant, adjacent to the pancreas, stomach and spleen.

Evaluation of variables influencing success and complication rates in canine total hip replacement: results from the British Veterinary Orthopaedic Association Canine Hip Registry (collation of data: 2010-2012).

The objective of this study was to assess the variables associated with complications of total hip replacement (THR) and report owner-assessed outcomes. Entries into the British Veterinary Orthopaedic Association-Canine Hip Registry (BVOA-CHR) between September 2011 and December 2012 were reviewed separately and in conjunction with previous data (January 2010-August 2011). An outcomes assessment questionnaire was used to collect data from owners.

Biomechanical comparison of canine fascia lata and thoracolumbar fascia: an in vitro evaluation of replacement tissues for body wall reconstruction.

Objectives: To compare the suitability of thoracolumbar fascia (TLF) and fascia lata (FL) for body wall defect repair in dogs, by examining their biomechanical properties and useable surface area.

Study Design: Experimental.

Animals: Dogs (n = 8).

Heavy metals exposure and hearing loss in US adolescents.

Introduction: Hearing loss is common and, in young persons, can compromise social development and educational achievement. Exposure to heavy metals has been proposed as an important risk factor for hearing loss.

Methods: We evaluated the cross-sectional associations between blood lead, blood mercury, and urinary cadmium and arsenic levels and audiometrically determined hearing loss in participants aged 12 to 19 years in the 2005-2008 National Health and Nutrition Examination Survey after accounting for the complex survey design.

Histopathologic investigation of the dimensions of the cochlear nerve canal in normal temporal bones.

Objective: Establish normative histopathologic data on the dimensions of the cochlear nerve canal (CNC).

Background: Evidence suggests that when the CNC is stenotic, the cochlear nerve may be hypoplastic. There is clear agreement in the literature that an internal auditory canal less than 2 mm in diameter is a relative contraindication to cochlear implantation in children.

Prevalence of noise-induced hearing-threshold shifts and hearing loss among US youths.

Objective: We investigated trends in noise-induced threshold shifts (NITSs), high-frequency hearing loss (HFHL), and low-frequency hearing loss (LFHL).

Methods: A total of 4310 adolescents 12 to 19 years of age completed audiometric testing during National Health and Nutrition Examination Surveys in 1988-1994 and 2005-2006. NITS criteria were audiometric patterns of decreased 3- to 6-kHz thresholds but preserved 0.
