The PennHIP method for the detection of canine hip dysplasia and its acceptance among practitioners

This thesis is based on Canine Hip Dysplasia and the usefulness of the PennHIP method for practitioners in its diagnosis, especially in the early stages of a dog’s life. It is a review of current papers on both CHD and the PennHIP method along with a questionnaire sent out to trained PennHIP members to gain an insight into the satisfaction the method brings to practicing Veterinarians and whether its pros out way the extra training and costs required

Time since immigration and ethnicity as predictors of physical activity among Canadian youth: a cross-sectional study.

Little is known about patterns of physical activity engaged in by youth after they immigrate to a new country. This study aims to investigate relationships between immigrant generation and ethnicity with physical activity, and to determine if the relationship between immigrant generation and physical activity was modified by ethnicity.The data sources were Cycle 6 (2009-2010) of the Canadian Health Behaviour in School-Aged Children Study and the 2006 Canada Census of Population. Participants (weighted n = 23,124) were young people from grades 6-10 in 436 schools. Students were asked where they were born, how long ago they moved to Canada, their ethnicity, and how many days a week they accumulated at least 60 minutes of moderate-to-vigorous physical activity (MVPA).Youth born outside of Canada were less likely to be active than peers born in Canada; 11% vs 15% reported 7 days/week of at least 60 minutes of MVPA (p = .001). MVPA increased with time since immigration. Compared to Canadian-born youth, youth who immigrated within the last 1-2 years were less likely to get sufficient MVPA on 4-6 days/week (odds ratio: 0.66, 95% confidence interval: 0.53-0.82) and 7 days/week (0.62; 0.43-0.89). East and South-East Asian youth were less active, regardless of time since immigration: 4-6 days/week (0.67; 0.58-0.79) and 7 days/week (0.37; 0.29-0.48).Time since immigration and ethnicity were associated with MVPA among Canadian youth. Mechanisms by which these differences occur need to be uncovered in order to identify barriers to physical activity participation among youth

Fever and Peripheral Emboli in an Immunocompetent Host: A Case of Aspergillus Endocarditis

Despite diagnostic and therapeutic advances in medical, surgical, and critical care, the mortality rate for Aspergillus endocarditis remains dismal (approaching 100%). We report a case of a 49 year old immunocompetent woman with recent aortic valve prosthesis who presents with fever, chills, sweats, left facial droop, left arm weakness, petechial rash and cyanotic toes. Initial trans-esophageal echo was normal but a repeat study revealed a 9 × 5 mm vegetation abutting the aortic prosthesis. Microbiological correlation could not be documented despite the presence of persistent fever through serial blood cultures, and the diagnosis of Aspergillus fumigatus endocarditis was ultimately made on embolectomy specimen when she developed an ischemic right leg. Aggressive medical treatment was initiated with intravenous voraconazole, liposomal amphotericin-B and heparin. The timing of surgical intervention was contemplated, but was precluded by multiple comorbidities. She succumbed to her illness after developing cerebral herniation following intraparenchymal hemorrhage. The effectiveness of combined medical intervention and surgical valve replacement for Aspergillus endocarditis is therefore contingent on high diagnostic suspicion and early echocardiographic detection in a high risk individual with features of culture-negative endocarditis
