Tales from the frontline: the colorectal battle against SARS

COLORECTAL DISEASE, Issue 2 2004
I. M. J. Bradford
Abstract Objective The recent worldwide epidemic of Severe Acute Respiratory Disease (SARS) caused over 800 deaths and had a major impact on the health services in affected communities. The impact of SARS on colorectal surgery, particularly service provision and training, is unknown. This paper reports these changes from a single colorectal unit at the centre of the outbreak. Patients and methods Hospital databases and electronic patient records covering the 4 months duration of the SARS epidemic and an equivalent period preceding SARS were compared. Data was collected for inpatient admissions, outpatient consultations, operative surgery, colonoscopy and waiting times for appointments or surgery. Results The SARS epidemic resulted in reductions of 52% for new outpatient attendances, 59% for review attendances, 51% for admissions, 32% for surgical procedures and 48% for colonoscopies. Major emergency procedures, cancer resections and complex major procedures were unaffected. Operative procedures by trainees reduced by 48% and procedures by specialists reduced by 21%. Patients awaiting early or urgent outpatient appointments rose by 200% with waiting times for colonoscopy increased by a median 3, 5 or 9 weeks for outpatient, inpatient or non-urgent cases, respectively. The waiting time for minor elective colorectal surgery was extended by 5 months. Conclusion SARS resulted in a major reduction in the colorectal surgical caseload. The consequences were evidenced by a detrimental effect on waiting times and colorectal training. However, serious pathology requiring emergency or complex surgery was still possible within these constraints. [source]


Agreement between bicarbonate measured on arterial and venous blood gases

EMERGENCY MEDICINE AUSTRALASIA, Issue 5-6 2004
Anne-Maree Kelly
Abstract Objective:, This study aims to determine the extent of agreement between venous and arterial bicarbonate for a group of emergency department patients with respiratory or metabolic illness requiring blood gas analysis as part of their evaluation. Methods:, This prospective study of patients who were deemed by their treating doctor to require an arterial blood gas analysis to determine their ventilatory or acid-base status, compared bicarbonate on an arterial and a venous sample taken as close to simultaneously as possible. Data were analysed using bias (Bland-Altman) methods. Subgroup analyses were performed for the metabolic, respiratory, chronic obstructive airways disease and acidotic subgroups. Results:, Two hundred and forty-six patients were entered into the study; 195 with acute respiratory disease and 51 with suspected metabolic derangement. The values of bicarbonate on arterial and venous samples showed close agreement with an average difference between the samples of 1.20 mmol/L (95% limits of agreement being ,2.73 to +5.13 mmol/L). Similar agreement was found for all subgroups. Conclusion:, Venous bicarbonate estimation shows a high level of agreement with the arterial value, with acceptably narrow 95% limits of agreement. These results suggest that venous bicarbonate estimation may be an acceptable substitute for arterial measurement. [source]


Detection of human bocavirus in respiratory, fecal, and blood samples by real-time PCR,

JOURNAL OF MEDICAL VIROLOGY, Issue 3 2009

Abstract Human bocavirus (HBoV) has been detected worldwide in respiratory samples. Two real-time PCR assays, targeting the non-structural protein (NP-1) and viral protein (VP-1) genes, were designed and validated to detect HBoV in patients with respiratory disease, gastroenteritis, or systemic illness. Sensitivity of the NP-1 and VP-1 assays were equal to the conventional PCR assay previously described by Allander et al. [2005: Proc Natl Acad Sci USA 102: 12891,12896] being 100%, and giving specificity of 94% and 93%, respectively. There was no cross-reaction identified with unrelated respiratory agents, or to human DNA. The limits of detection were 10 copies of genomic DNA equivalents per reaction for both assays. The assays were used to screen three different sample populations, combined nose, and throat swabs (n,=,96) from children with acute respiratory disease, fecal samples (n,=,375) from adults, and children with gastroenteritis and whole blood (n,=,229) collected from 31 immunocompromised children taken over an 18-month period. In total 17 (18%) respiratory samples and 18 (4.8%) fecal samples were identified as having HBoV present. Of the pediatric whole blood specimens investigated, HBoV was detected in six (2.6%) samples from four patients. In summary, two real-time PCR assays targeting different genes were designed and validated for use as screening methods for the detection of HBoV. HBoV was found in three different specimen types: parent-collected combined nose,throat swabs, fecal samples collected from symptomatic individuals and whole blood from immunocompromised children. J.

A longitudinal study of urinary dipstick parameters in wild chimpanzees (Pan troglodytes verus) in Côte d'Ivoire

Abstract We performed 796 dip-stick tests on urine from 100 wild West African chimpanzees (Pan troglodytes verus) from 4 habituated groups in the tropical rain forest of Taï National Park, Cote d'Ivoire, to establish reference values for health monitoring. Specific gravity was also measured on 359 urine samples from 62 chimpanzees. The effect of age, sex, group, month, estrus, pregnancy, meat consumption, and acute respiratory disease on pH, leucocytes, protein, blood, hemoglobin, and glucose was examined using ordinal logistic regression. The presence of nitrite, ketones, bilirubin, and urobilinogen in urine was also recorded. Outbreak of acute respiratory disease did not influence any of the urinary parameters. Thirty-seven percent of the samples had a pH <7 and the whole range of pH was found through the year, in all age groups, and in both sexes. Meat consumption lowered the urinary pH. Our results show that all pH levels must be considered normal for the West African chimpanzee subspecies P. troglodytes verus living in the rainforest. We also found a cluster of glucose-positive samples at a specific point in time which was not attributed to diabetes mellitus. These findings highlight that there are differences in normal physiological parameters among wild chimpanzees living in different habitats. Am. J. Primatol. 72:689,698, 2010. © 2010 Wiley-Liss, Inc.

Survey of neonatal respiratory support strategies

ACTA PAEDIATRICA, Issue 8 2007

Abstract Aim: To survey current practice regarding neonatal respiratory support strategies to determine whether it reflected evidence from randomised trials. Methods: A questionnaire (in Supplementary Material online) survey of all U.K. neonatal units was undertaken to determine what modes of ventilation, types of endotracheal tube, lung function monitoring and oxygen saturation levels were used. Results: There was an 80% response rate. Most (73%) units used in prematurely born infants (in the first 24 h) the intermittent positive pressure ventilation, and other respiratory modes included: CPAP (2%), triggered ventilation with or without volume guarantee (22%) and high frequency oscillation (2%). Only 15% of units used assist control mode for weaning; the preferred weaning mode was synchronous intermittent mandatory ventilation (73%). Few units used shouldered endotracheal tubes (3%) or lung function measurements (25%) to aid choice of ventilator settings. Oxygen saturation levels from 80% to 98% were used, levels greater or equal to 95% were used by 11% of units for infants with acute respiratory disease but by 34% of units for BPD infants (p < 0.001). Conclusion: Many practitioners do not base their choice of neonatal respiratory support strategies on the results of large randomised trials; more effective methods are required to ensure evidence-based practice.
