Abstract
In 2010, Coxiella burnetii was identified in 75% of northern fur seal placentas from a single rookery in Alaska, but nothing was known about the significance of this organism in the population. Although many infectious organisms cause increased cell death, C. burnetii has been shown to suppress apoptosis of the host macrophages as an intracellular survival mechanism. To determine if infection induces a similar functional change in the placenta, immunohistochemistry for antibodies to cleaved caspase-3 (activated caspase-3) and the (TDT)-mediated dUTP-digoxigenin nick end labeling (TUNEL) technique were used to compare the amount of placental apoptosis in infected and noninfected placentas. There was a statistically significant difference in the frequency of apoptotic cells between infected and uninfected placentas, with more apoptosis identified in the uninfected placentas. This finding suggests that the survival mechanism of C. burnetii in host macrophages to reduce apoptosis may also be utilized in trophoblasts. The significance of decreased trophoblastic apoptosis for the northern fur seal fetus requires further investigation.

Abstract
In 2010, Coxiella burnetii was identified at a high prevalence in the placentas of Northern fur seals (Callorhinus ursinus) collected at a single rookery on St. Paul Island Alaska; an area of the United States where the agent was not known to be present. As contamination was hypothesized as a potential cause of false positives, but nothing was known about environmental C. burnetii in the region, an environmental survey was conducted to look for the prevalence and distribution of the organism on the island. While environmental prevalence was low, two strains of the organism were identified using PCR targeting the COM1 and IS1111 genes. The two strains are consistent with the organism that has been increasingly identified in marine mammals as well as a strain type more commonly found in terrestrial environments and associated with disease in humans and terrestrial animals. Further work is needed to elucidate information regarding the ecology of this organism in this region, particularly in association with the coastal environment.

Abstract
The heartwoods of tree species containing tropolone compounds in their extractive components are classed among the more durable woods. Two new tropolones, namely, alpha-thujaplicinol and pygmaein from the heartwood of Cupressus pygmaea, were also found to exhibit strong fungitoxic properties active against a number of wood-destroying fungi. The hydroxyl group appears to be the functional grouping which is largely responsible for the fungicidal action exhibited by this type of compound.

Abstract
Background and Aims Patients often wait many months to see a neurologist for the first time. With the introduction of targets for maximum waiting times there is a need for novel approaches. Real time telemedicine by videolink (VL) is one such method and we aimed to replicate this in Aberdeen. Methods Patients were seen by VL by two Irish-based neurologists, one experienced in telemedicine, the other not. A senior trainee neurologist present with some of the patients validated the telemedicine diagnosis and management with his own face-to-face (FF) assessment. Satisfaction was assessed by questionnaires. Numbers requiring investigations and review were recorded as were representations to neurology over six months. Results Forty-four patients were seen. Satisfaction was higher and review rates were similar to previous cohorts seen by FF and VL. There was no difference between the two neurologists. There was complete diagnostic agreement between the VL and FF neurologists. There was a diagnostic change in a single patient after six months follow-up. Conclusion Neurology consultation using VL is safe and effective as well as acceptable, and the necessary skills were acquired rapidly by a telemedicine-naive neurologist. Telemedicine using VL can contribute to waiting list reduction, and is likely to be most useful in rural areas.

Abstract
Wild animals can play an important role in the epidemiology of infectious disease with significant public health, economic and ecological consequences. As it is often challenging to conduct unbiased surveillance in free-ranging mammal populations, passive, opportunistic case identification has been widely used for detection of disease events in wild animals. This study evaluated the role of different agencies and organizations in the Rocky Mountain Region of the USA to identify significant wildlife health events or aggregate information from multiple sources. Overall wildlife rehabilitators were in contact with the greatest number of animals; however, the data from these groups, in its current state, are insufficient for surveillance purposes. Wild animal data from all survey groups aggregated at the level of state wildlife organizations; these agencies are therefore central in this type of surveillance activity and require sufficient resources to ensure that appropriate testing is conducted.

Abstract
Warts are a common skin complaint in childhood. We describe 3 unusual cases in which inadvertent tissue injury was caused during the treatment of viral warts by a commercially available cryotherapy device. In each case there was a failure to follow the instructions provided correctly. If such devices are to remain available for public use we feel changes should be implemented to reduce the risk of such injuries occurring again in the future. Alternatively, cryotherapy as a treatment modality should remain in the realm of the trained health care professional.

Abstract
BACKGROUND The Paediatric Oncology Centres (POCs) treating childhood cancer in South East England produce unified supportive care guidelines for use in the secondary pediatric (shared care) units. This study evaluated the adherence to current guidelines for febrile neutropenia (FN) and documented outcome in terms of bacterial isolates, antibiotic resistance patterns, length of hospital stay, and mortality. PROCEDURE Prospective study of pediatric FN admissions between July 2001 and December 2002. RESULTS Data were received on 433 eligible FN episodes in 212 patients. The recommended empirical antibiotics (piptazobactam + gentamicin) were used in 354 (82%) admissions. Blood cultures were positive in 129 episodes (30%). Gram-positive organisms predominated (120/149 organisms isolated) and the majority were coagulase-negative Staphylococci (95/120). There were 27 Gram-negative isolates and 1 fungal isolate. No Gram-negative isolate was resistant to both first-line antibiotics. Only one death was recorded in the study group. The median length of hospital stay was 5 days. CONCLUSIONS We obtained data on a large number of shared care episodes of FN. The antibiotic guidelines were followed in most episodes. Bacteremia was common, but little resistance to first-line antibiotics was documented among Gram-negative isolates, confirming the safety of the strategy in our population.

Abstract
The purpose of this study was to explore patient opinion about asking healthcare professionals to wash their hands prior to a clinical procedure and to explore if MRSA status and access to patient information about infection control would influence anxiety about asking. A descriptive survey was undertaken using a semi-structured questionnaire. The questionnaire was distributed to a randomised convenience sample of 185 in-patients across all departments of an acute NHS Trust hospital (response rate 59.4%). Spearman's rank order and Kendall Tau-b tests were used to analyse specific correlations. Respondents were more confident than anxious to be involved in a campaign that asked patients to ask staff to wash their hands. Patients were more anxious to ask if previous admission episodes were fewer, if their knowledge of MRSA was high and if there was less information about infection control available. Less anxiety was associated with patients who had MRSA in the past and the suggestion that staff wore badges saying 'It's OK to ask'.

Abstract
This study explored the relationship between the initial stability of the femoral component and penetration of cement into the graft bed following impaction allografting. Impaction allografting was carried out in human cadaveric femurs. In one group the cement was pressurised conventionally but in the other it was not pressurised. Migration and micromotion of the implant were measured under simulated walking loads. The specimens were then cross-sectioned and penetration of the cement measured. Around the distal half of the implant we found approximately 70% and 40% of contact of the cement with the endosteum in the pressure and no-pressure groups, respectively. The distal migration/micromotion, and valgus/varus migration were significantly higher in the no-pressure group than in that subjected to pressure. These motion components correlated negatively with the mean area of cement and its contact with the endosteum. The presence of cement at the endosteum appears to play an important role in the initial stability of the implant following impaction allografting.

Abstract
INTRODUCTION Patients with end-stage liver disease often develop hepatic encephalopathy. The loss in cognitive abilities results in marked economic loss to the patient and health care community. We report hospital admission rates and economic impact of patients with end-stage liver disease suffering from hepatic encephalopathy. METHODS The medical records were reviewed involving liver transplant patients started on lactulose or rifaximin therapy after presenting with stage 2 hepatic encephalopathy from January 2004 to November 2005. Information collected included demographics, hospitalizations required for hepatic encephalopathy, economic data, and Model for End-stage Liver Disease (MELD) score. RESULTS Thirty-nine patients met study criteria: 24 patients treated with lactulose (group one) and 15 with rifaximin (group two). Group one included 18 men and six women of mean age 48 (range 39 to 58), average MELD 14 (range 10 to 19). Group two included 10 men and five women of mean age 47 (range 42 to 58), average MELD 15 (range 10 to 19). Group one patients required 19 hospitalizations overall: three patients with three hospitalizations, four patients with two hospitalizations, and two patients required one hospitalization. Total drug cost per month was 50 dollars(group one) and 620 dollars(group two). The average annual cost of hospitalization, emergency room visit, and drug per patient treated was 13,284.96 dollars for a total of 318,839 dollars (range 5005 dollars to 26,255 dollars, including drug cost and hospital care). Group two required three hospitalizations, all three with one visit. The average annual cost of hospitalization, emergency room visit, and drug per patient treated was 7958.13 dollars for a total of 119,372 dollars (range 6005 dollars to 19,255 dollars, including drug cost and hospital care). The total cost of therapy per patient per year was 13,285 dollars (group one) versus 7958 dollars (group two). The average length of stay was shorter in group two [3.5 days (range 3 to 4)] versus group 1 [5.0 days (range 3 to 10); P < .0001]. CONCLUSION These pilot data demonstrate the marked difference in economic costs for the treatment of hepatic encephalopathy. The results also show that in comparative groups, the economic gains are quickly lost when using lactulose.

Abstract
During 2002 through 2004, 15 patients with Rocky Mountain spotted fever (RMSF) were identified in a rural community in Arizona where the disease had not been previously reported. The outbreak was associated with Rickettsia rickettsii in an unexpected tick vector, the brown dog tick (Rhipicephalus sanguineus), which had not been previously associated with RMSF transmission in the United States. We investigated the extent of exposure to R. rickettsii in the local area through serologic evaluations of children and dogs in 2003-2004, and in canine sera from 1996. Antibodies to R. rickettsii at titers > or = 32 were detected in 10% of children and 70% of dogs in the outbreak community and 16% of children and 57% of dogs in a neighboring community. In comparison, only 5% of canine samples from 1996 had anti-R. rickettsii antibodies at titers > or = 32. These results suggest that exposures to RMSF have increased over the past 9 years, and that RMSF may now be endemic in this region.

Abstract
Although Cryptococcus gattii has emerged as an important pathogen of humans and domestic animals on Vancouver Island, Canada since 1999; its distribution in regional wildlife species is largely unknown. Opportunistic sampling methods were employed to obtain nasal swabs for fungal culture from wild mammal species residing within the coastal Douglas fir biogeoclimatic zone on the southeast coast of the island. Samples were collected from 91 animals representing 14 species. Cryptococcus gattii was isolated from the nasal swabs of two eastern gray squirrels (Sciurus carolinensis) trapped in Duncan, British Columbia. The relative proportion of nasal colonization in wild mammal species is consistent with findings in domestic animals, suggesting that animals may be good indicators of environmental organisms.
