Ambulatory electroencephalogram in children:a prospective clinical audit of 100 cases

Ambulatory electroencephalogram has been used for differentiating epileptic from nonepileptic events, recording seizure frequency and classification of seizure type. We studied 100 consecutive children prospectively aged 11 days to 16 years that were referred for an ambulatory electroencephalogram to a regional children's hospital. Ambulatory electroencephalogram was clinically useful in contributing to a clinical diagnosis in 71% of children who were referred with a range of clinical questions. A diagnosis of epileptic disorder was confirmed by obtaining an ictal record in 26% and this included 11 children that had previously normal awake and or sleep electroencephalogram. We recommend making a telephone check of the current target event frequency and prioritising those with typical events on most days in order to improve the frequency of recording a typical attack.

Studies on enhanced surface disinfection and skin antisepsis using chlorhexidine and eucalyptus oil

Healthcare associated infections may arise from many sources, including patient?s own skin flora and the clinical environment, and inflict a significant burden within the health service. Adequate and effective skin antisepsis and surface disinfection are therefore essential factors in infection control. Current EPIC guidelines recommend 2 % chlorhexidine (CHG) in 70 % isopropyl alcohol (IPA) for skin antisepsis however poor penetration has been reported. Eucalyptus oil (EO) is a known permeation enhancer, producing synergistic antimicrobial activity when combined with CHG. In this current study, the antimicrobial efficacy of EO and its main constituent 1,8-cineole were assessed against a panel of clinically relevant microorganisms, alone and in combination with CHG. The superior antimicrobial efficacy of EO compared with 1,8-cineole, and synergistic effects with CHG against planktonic and biofilm cultures, confirmed its suitability for use in subsequent studies within this thesis. Impregnation of EO, CHG and IPA onto prototype hard surface disinfectant wipes demonstrated significantly improved efficacy compared with CHG/IPA wipes, with clear reductions in the time required to eliminate biofilms. Optimisation of the EO/CHG/IPA formulation resulted in the development of Euclean® wipes, with simulated-use and time kill studies confirming their ability to remove microbial surface contamination, prevent cross contamination and eliminate biofilms within 10 minutes. The employment of isothermal calorimetry provided additional information on the type and rate of antimicrobial activity possessed by Euclean® wipes. A clinical audit of the Euclean® wipes at Birmingham Children?s Hospital, Birmingham, U.K. revealed divided staff opinion, with the highest cited advantage and disadvantage concerning the odour. Finally, skin penetration and cell toxicity studies of EO/CHG biopatches and Euclean® solution developed during this study, revealed no permeation into human skin following biopatch application, and no significant toxicity. These current studies enhance the knowledge regarding EO and its potential applications.

An evaluation of quinolone prescribing in a group of acute hospitals:Development of an objective measure of usage

Objectives: To develop an objective measure to enable hospital Trusts to compare their use of antibiotics. Design: Self-completion, postal questionnaire with telephone follow up. Sample: 4 hospital trusts in the English Midlands. Results: The survey showed that it was possible to collect data concerning the number of Defined Daily Doses (DDD's) of quinolone antibiotic dispensed per Finished Consultant Episode (FCE) in each Trust.. In the 4 trusts studied the mean DDD/FCE was 0.197 (range 0.117 to 0.258). This indicates that based on a typical course length of 5 days, 3.9% of patient episodes resulted in the prescription of a quinolone antibiotic. Antibiotic prescribing control measures in each Trust were found to be comparable. Conclusion: The measure will enable Trusts to objectively compare their usage of quinolone antibiotics and use this information to carry out clinical audit should differences be recorded. This is likely to be applicable to other groups of antibiotics.

Diabetes in the very elderly:need for an individualised approach

Background: Intensive risk factor management is recommended for individuals with diabetes. However, it is not known if such an approach is appropriate in the elderly with multiple comorbidities and limited life expectancy. The aim of this study was to characterise a cohort of very elderly individuals with diabetes and assess the impact of known risk factors on mortality. Methods: This was a retrospective audit approved by the clinical audit lead. All patients aged >80 years who attended diabetes outpatient clinics 2 years prior to the date of the audit (April 2012) were identified from clinic records. A detailed history including demographics, comorbidities and treatment were collected. Blood pressure readings, HbA1c, cholesterol and renal function were extracted and the mean of these readings was recorded. Survival status at 2 years was recorded for all patients. Statistical analysis was performed using SPSS19. Results: Data were available for 864 (381 male, 483 female) patients. The majority (75%) lived in their own home. More than 60% had multiple comorbidities and 25% had a prior history of cardiovascular disease. Two-thirds of the patients had more than one hospital admission in 2 years and a third had more than three admissions. 60% were on either insulin or a sulfonylurea. Mean HbA1c was 7.6%, cholesterol 4.2mmol/l, systolic blood pressure 145mmHg and eGFR 53ml/min. Over 2 years, 174 (20%)had died. Age, creatinine and previous coronary heart disease were significant predictors of death. Conclusion: The benefits of intensive diabetes management appear to be uncertain in very elderly patients. The need for intensive treatment must therefore be individualised to each patient.
