Abstract
Pepper chat fruit viroid (PCFVd), a species of Pospiviroid, was first discovered in a capsicum crop in the Netherlands in 2006 (4) and was then reported only in Thailand (2) and Canada. The mechanism of international spread was not known, but movement with traded seed was suspected. PCFVd is transmissible through capsicum seed (4) and very probably through tomato seed, like other pospiviroids. The viroid causes disease in capsicum and tomato and experiments by others indicate a capacity to cause disease in potato. It poses a biosecurity threat to crops internationally. PCFVd was intercepted by the Australian Government Department of Agriculture, Fisheries, and Forestry (DAFF) in five shipments of tomato seed (Solanum lycopersicum) exported from Israel and Thailand in September and October 2012. Batches of up to 20,000 seeds were sampled from each seed lot in a shipment and total nucleic acids were extracted from sub-samples, each of about 400 seeds, following a method similar to Hoshino et al. (1). PCFVd was initially detected when reverse transcription PCR using the generic pospiviroid primers Pospi1-FW and Pospi1-RE (3) produced amplicons of 189 bp, which were then sequenced. The PCFVd specific primers AP FW1 and AP RE2 (4) were used to amplify the remainder of the viroid genome, which was directly sequenced. Overlapping sequences were aligned to produce complete sequences of 349 bases, one from seed from Thailand and two from seed from Israel (GenBank: KC762952, KC762953, KC762954). Searches of the GenBank nucleotide non-redundant database indicated close matches with sequences from PCFVd isolates from tomato in Thailand (2); alignments generated by BLAST showed the sequences differed from those from Thailand at only 2 to 18 nucleotide positions, equating to 95 to 99% identity. PCFVd sequences from seed from Thailand were almost identical (>99%) to the sequences from seed from Israel. Many sub-samples were negative, indicating that the number of contaminated seeds was very small in some shipments. The positive sub-samples as a proportion of the total number of sub-samples tested from the five shipments was 1/1, 1/5, 1/1, 12/50, and 7/50. Tomato and capsicum seed are produced in many countries and often traded through second countries. The infected tomato seed shipments intercepted by DAFF were destroyed or re-exported following Australian regulations. Other countries were informed through the International Plant Protection Convention. This pest viroid has not been intercepted by Australian authorities before and has not been detected in recent Australian survey work (data not shown). References: (1) S. Hoshino et al. Res. Bull.

Abstract
OBJECTIVE The electrical activity of the diaphragm (Edi) reflects neural respiratory drive. Edi peak correlates with inspiratory drive and Edi minimum (Edi min) correlates with the tonic activity of the diaphragm. Edi data in non-ventilated preterm neonates have not been determined.The primary aim of this study was to determine Edi values in non-ventilated preterm neonates throughout postnatal maturation and with various types of noninvasive respiratory support. The secondary aim was to evaluate the success or complications of placement of the Edi catheter in premature neonates. STUDY DESIGN This was a prospective observational study of non-ventilated neonates <33 weeks gestation. Data were collected weekly using an Edi catheter placed in neonates on highflow nasal cannula (HFNC), nasal cannula (NC) or room air (RA). Clinical stability was determined by measuring heart rate (HR), respiratory rate (RR) and oxygen saturation (Sats). Success and adverse events of Edi catheter placement was monitored. Statistics were obtained by analysis of variance, P<0.05 was considered significant. RESULT Seventeen neonates were enrolled at 26 to 33 weeks postmenstrual age and studied from 1 to 10 weeks in duration. Overall Edi peak was 10.8±3.7 mcV (range 3.7 to 18.7) and Edi min was 2.8±1.1 mcV (range 0.8 to 7.6). There was no difference in Edi peak and min over postmenstrual ages within or between neonates, and no difference between those neonates on HFNC, NC or RA. HR, RR and Sats were not different over postmenstrual age or between any groups. The Edi catheter was placed successfully in 100% of these neonates. There were no adverse events noted. CONCLUSION In clinically stable neonates, the inspiratory drive (Edi peak) and tonic activity (Edi min) do not change with postnatal maturation or with the level of noninvasive respiratory support. The Edi catheter can be placed successfully in these premature neonates. These Edi data have the potential to guide ventilatory management of premature neonates.

Abstract
This article describes a quality assurance study of patient utilization of adaptive equipment. A major component of occupational therapy practice has been the prescription of equipment to increase independent living. However, little information exists in the literature regarding patients use of equipment. The researchers found an unexpected high rate (85%) of utilization. Reasons for non-utilization are described. Caution is needed in interpreting the results as non-responders (22%) may have been primarily non-users. Based on the findings, the authors suggest establishing a system to retrieve items needed for a short time and individualizing the process of issuing equipment based on environmental and personal needs as opposed to the standard protocol based on a diagnosis.

Abstract
Enhancing laboratory animal welfare, particularly in rodents, has been achieved through environmental enrichment in caging systems. Traditional enrichment such as adding objects has shown to impact development, reproductive and maternal performance as well as cognition. However, effects of increased spatial complexity as part of larger novel caging systems have not been investigated. While adoption of caging systems with increased spatial complexity seems uncontroversial from a welfare perspective, effects of such housing on the development and task performance of experimental animals remains unclear. In this study, we investigate differences in key behaviours and cognitive performance between Lister Hooded rats housed in traditional (single-shelf) cages (‘basic’) and those housed in larger cages with an additional shelf (‘enriched’). We found minor differences in maternal behaviour, such as nursing and offspring development. Further, we compared task performance in females, using a hippocampus-dependent task (T-maze) and a hippocampus-independent task (Novel Object Recognition, NOR). While in the T-maze no differences in either the rate of learning or probe trial performance were found, in the NOR task females housed in enriched cages performed better than those housed in basic cages. Our results show that increased spatial complexity does not significantly affect development and maternal performance but may enhance learning in females for a non-spatial task. Increased spatial complexity does not appear to have the same effects on behaviour and development as traditional enrichment. Thus, our results suggest no effect of housing conditions on the development of most behaviours in experimental animals housed in spatially enriched caging systems.

Abstract
INTRODUCTION Common bile duct (CBD) stones can cause serious morbidity or mortality, and evidence for them should be sought in all patients with symptomatic gallstones undergoing cholecystectomy. Routine intra-operative cholangiography (IOC) involves a large commitment of time and resources, so a policy of selective cholangiography was adopted. This study prospectively evaluated the policy of selective cholangiography for patients suspected of having choledocholithiasis, and aimed to identify the factors most likely to predict the presence of CBD stones positively. PATIENTS AND METHODS Data from 501 consecutive patients undergoing laparoscopic cholecystectomy (LC) for symptomatic gallstones, of whom 166 underwent IOC for suspected CBD stones, were prospectively collected. Suspicion of choledocholithiasis was based upon: (i) deranged liver function tests (past or present); (ii) history of jaundice (past or present) or acute pancreatitis; (iii) a dilated CBD or demonstration of CBD stones on imaging; or (iv) a combination of these factors. Patient demographics, intra-operative findings, complications and clinical outcomes were recorded. RESULTS Sixty-four cholangiograms were positive (39%). All indications for cholangiogram yielded positive results. Current jaundice yielded the highest positive predictive value (PPV; 86%). A dilated CBD on pre-operative imaging gave a PPV of 45% for CBD calculi; a history of pancreatitis produced a 26% PPV for CBD calculi. Patients with the presence of several factors suggestive of CBD stones yielded higher numbers of positive cholangiograms. Of the 64 patients having a laparoscopic common bile duct exploration (LCBDE), four (6%) required endoscopic retrograde cholangiopancreatography (ERCP) for retained stones (94% successful surgical clearance of the common bile duct) and one (2%) for a bile leak. Of the 335 patients undergoing LC alone, three (0.9%) re-presented with a retained stone, requiring intervention. There were 12 (7%) requiring conversion to open operation. CONCLUSIONS A selective policy for intra-operative cholangiography yields acceptably high positive results. Pre-operatively, asymptomatic bile duct stones rarely present following LC; thus, routine imaging of the biliary tree for occult calculi can safely be avoided. Therefore, a rationing approach to the use of intra-operative imaging based on the pre-operative indicators presented in this paper, successfully identifies those patients with bile duct stones requiring exploration. Laparoscopic bile duct exploration, performed by an experienced laparoscopic surgeon, is a safe and effective method of clearing the bile duct of calculi, with minimal complications, avoiding the necessity for an additional intervention and prolonged hospital stay.

Abstract
A patient was presented with four days of vomiting, abdominal pain and sweating. At presentation the Capillary Blood Glucose (CBG) was 1.7 mmol/L, the Blood Pressure (BP) was 182/102 mmHg, and the pulse 100 bpm. On examination, he was sweaty, pale and cold. The initial differential diagnosis was hypoglycaemia secondary to insulin abuse, hypoadrenalism or insulinoma, the transient hypertension being considered a consequence of sympathetic stimulation. He remained clinically well overnight with a CBG of 10-14 mmol/L following intravenous glucose. The next morning he complained of nausea and abdominal pain. The BP had risen to 203/127 mmHg when he was later reviewed, having been given 10mg intramuscular metoclopramide. Shortly afterwards, he developed acute pulmonary oedema and had become hypoglycaemic again; a phaeochromocytoma crisis was suspected. Treatment with alpha-adrenoceptor blockade with intravenous phenoxybenzamine was advised. However, the patient deteriorated and died in the Intensive Care Unit within two hours. Autopsy examination confirmed a phaeochromocytoma in the left adrenal, with haemorrhage within the head of pancreas, but no evidence of a pancreatic tumour.

Abstract
Drilling consists of 2 processes: breaking the formation with a bit and removing the drilled cuttings. In rotary drilling, rotational speed and weight on bit are used to control drilling, and the optimization of these parameters can markedly improve drilling performance. Although fluids are used for cuttings removal in terrestrial drilling, most planetary drilling systems conduct dry drilling with an auger. Chip removal via water-ice sublimation (when excavating water-ice-bound formations at pressure below the triple point of water) and pneumatic systems are also possible. Pneumatic systems use the gas or vaporization products of a high-density liquid brought from Earth, gas provided by an in situ compressor, or combustion products of a monopropellant. Drill bits can be divided into coring bits, which excavate an annular shaped hole, and full-faced bits. While cylindrical cores are generally superior as scientific samples, and coring drills have better performance characteristics, full-faced bits are simpler systems because the handling of a core requires a very complex robotic mechanism. The greatest constraints to extraterrestrial drilling are (1) the extreme environmental conditions, such as temperature, dust, and pressure; (2) the light-time communications delay, which necessitates highly autonomous systems; and (3) the mission and science constraints, such as mass and power budgets and the types of drilled samples needed for scientific analysis. A classification scheme based on drilling depth is proposed. Each of the 4 depth categories (surface drills, 1-meter class drills, 10-meter class drills, and deep drills) has distinct technological profiles and scientific ramifications.
