[source] The braun thermoscan thermometer: validation of normal ranges in a paediatric practicePEDIATRIC ANESTHESIA, Issue 9 2002C.A. Streets Introduction Pyrexia is a common cause of operative cancellation in paediatric practice, and so the accurate determination of temperature is of paramount importance. Recently the Braun ThermoScan infrared aural thermometer has been introduced to Derriford Hospital as a safe and non-invasive technique for measuring temperature. Initially the published upper limits of normal for this technique appeared to be higher than expected. Initial experiences with the thermometer in Derriford Hospital produced high temperature readings in children who were otherwise clinically well. The aim of this study was to compare the manufacturer's published normal ranges with those obtained from a general paediatric population. Methods Ethics Committee approval was obtained. The study was conducted between July and November 2001. Patients less than 16 years of age, and admitted to either the Day Surgical Unit or the general paediatric wards for elective surgery were included. Each child had its temperature measured on admission using the Braun ThermoScan aural thermometer. The ages and temperatures were recorded, and the values compared with the manufacturer's normal ranges using standard error of the means. Results Preliminary data are reported from 248 children: 1,2 years (n = 30), 3,10 years (n = 159), and 11,15 years (n = 59). The table demonstrates that there is no significant statistical difference between the manufacturer's ranges and those of the Derriford Hospital paediatric elective surgical population. Discussion The Braun ThermoScan infrared aural thermometer is considered to be a safe, hygienic, and convenient technique for measuring temperature. Despite initial misgivings that a temperature approaching 38°C could not be considered normal, this study has confirmed that the manufacturer's published normal ranges are indeed compatible with those obtained from a district general hospital paediatric population. Conclusion This study validates the manufacturer's published normal range for the Braun ThermoScan thermometer. This therefore leaves a clinical dilemma , does a child with a temperature of 37.9°C have a pyrexia or not? [source] Effect of epilepsy magnetic source imaging on intracranial electrode placement,ANNALS OF NEUROLOGY, Issue 6 2009MSPH, Robert C. Knowlton MD Objective Intracranial electroencephalography (ICEEG) with chronically implanted electrodes is a costly invasive diagnostic procedure that remains necessary for a large proportion of patients who undergo evaluation for epilepsy surgery. This study was designed to evaluate whether magnetic source imaging (MSI), a noninvasive test based on magnetoencephalography source localization, can supplement ICEEG by affecting electrode placement to improve sampling of the seizure onset zone(s). Methods Of 298 consecutive epilepsy surgery candidates (between 2001 and 2006), 160 patients were prospectively enrolled by insufficient localization from seizure monitoring and magnetic resonance imaging results. Before presenting MSI results, decisions were made whether to proceed with ICEEG, and if so, where to place electrodes such that the hypothetical seizure-onset zone would be sampled. MSI results were then provided with allowance of changes to the original plan. Results MSI indicated additional electrode coverage in 18 of 77 (23%) ICEEG cases. In 39% (95% confidence interval, 16.4,61.4), seizure-onset ICEEG patterns involved the additional electrodes indicated by MSI. Sixty-two patients underwent surgical resection based on ICEEG recording of seizures. Highly localized MSI was significantly associated with seizure-free outcome (mean, 3.4 years; minimum, >1 year) for the entire surgical population (n = 62). Interpretation MSI spike localization increases the chance that the seizure-onset zone is sampled when patients undergo ICEEG for presurgical epilepsy evaluations. The clinical impact of this effect, improving diagnostic yield of ICEEG, should be considered in surgery candidates who do not have satisfactory indication of epilepsy localization from seizure semiology, electroencephalogram, and magnetic resonance imaging.

[source] Acute renal failure in the surgical settingANZ JOURNAL OF SURGERY, Issue 3 2003Paul Carmichael Acute renal failure (ARF) is an unwelcome complication of major surgical procedures that contributes to surgical morbidity and mortality. Acute renal failure associated with surgery may account for 18,47% of all cases of hospital-acquired ARF. The overall incidence of ARF in surgical patients has been estimated at 1.2%, although is higher in at-risk groups. Mortality of patients with ARF remains disturbingly high, ranging from 25% to 90%, despite advances in dialysis and intensive care support. Appreciation of at-risk surgical populations coupled with intensive perioperative care has the capacity to reduce the incidence of ARF and by implication mortality. Developments in understanding the pathophysiology of ARF may eventually result in newer therapeutic strategies to either prevent or accelerate recovery from ARF. At present the best form of treatment is prevention. In this review the epidemiology, pathophysiology, diagnosis, treatment and possible prevention of ARF will be discussed. [source] |
