Nosocomial blood stream infection (or nosocomial bacteremia) is a common problem in hospitals worldwide, including Malaysia. A three-year prospective cohort study (October 2003-March 2007) of the incidences, risk factors, and patterns of the microorganisms causing bacteremia was conducted using a validated surveillance form in three intensive care units (ICUs) in Malaysia. Center for Disease Control criteria were used to diagnose bacteremia. Patients were monitored from admission until the end point of study, which was the first detection of bacteremia in the blood in each patient. The frequency of occurrence of bacteremia with clinical symptoms was 10.7% (n = 23). Bacteremia was observed to occur within a mean length of stay of 10 days in ICU. The rate of device-related infection was 10.4% per device utilization days with a device utilization rate of 95.9%/1000 patient days. The total number of patient days was 2309 and the period of device utilization was 2211 days. The common bacteria detected were extended-spectrum beta-lactamases (ESBLs) Klebsiella pneumoniae (n = 6); Pseudomonas aeruginosa (n = 6); Acinetobacter species (n = 5); Methicillin-resistant Staphylococcus aureus (MRSA)(n = 3); and (non- ESBL) Klebsiella pneumoniae (n = 2). Multivariable analysis using Cox Proportional Hazard Model showed that the predictors for developing bacteremia were cancer, MRSA carriage, duration of central venous catheter (CVC) infusion, frequency change of CVC, and the administration of hydrocortisone drugs. These results indicate that a combination of nursing and medical interventions as well as patients' severity of illness could lead to bacteremia in ICU. Strategic implementation of quality assurance measures in ICUs could help to control this problem.

Introduction: Infant feeding choices made by mothers in the context of HIV infection depend on a number of factors. In our environment, the relative contribution of some of these factors is not known. Methods: The infant feeding practices of HIV positive mothers seen over a decade (July 2004 and December 2015) at a large HIV treatment centre in Lagos, South-western Nigeria were reviewed. Information on maternal socio-economic characteristics, obstetric, HIV treatment history and infant feeding choices were extracted from the program data base for analysis with SPSS version 20. Results: Exclusive formula feeding (EFF) was the most common feeding practice of the mothers ( 86.4%). However, it decreased from 95.3 % before 2010 to 79.5% after 2010. Exclusive breastfeeding (EBF) was practised by only 9.0% of the mothers. Mixed breastfeeding practice increased from 1.1% pre-2010 to 4.1% post-2010. The provision of free infant formula was found not to influence significantly the EFF or EBF rates but the MBF rate. MBF rate decreased from 3.0% pre-free formula to 1.7% after the introduction of free infant formula. Conclusion: Exclusive formula feeding was the most practised infant feeding method in this study (86.4%). Change in infant feeding guidelines was found to influence the infant feeding choice of HIV positive mothers. Health workers implementing PMTCT programs in our setting should be made aware of the risk of mixed breastfeeding with the new guidelines and educate mothers on its dangers at every contact with the health system.

To date, the College of Radiology (CoR) does not see any clear benefit in performing whole body screening computed tomography (CT) examinations in healthy asymptomatic individuals. There are radiation risk issues in CT and principles of screening should be adhered to. There may be a role for targeted cardiac screening CT that derives calcium score, especially for asymptomatic medium-risk individuals and CT colonography when used as part of a strategic programme for colorectal cancer screening in those 50 years and older. However, population based screening CT examinations may become appropriate when evidence emerges regarding a clear benefit for the patient outweighing the associated radiation risks.

PURPOSE: To report rates of and reasons for operation cancellation, and to prioritize areas of improvement. METHODS: Retrospective data were extracted from the monthly reports of cancelled listed operations. Data on 14 theatres were collected by the office of quality assurance at Jordan University Hospital from August 2012 to April 2016. Rates and reasons for operation cancellation were investigated. A Pareto chart was constructed to identify the reasons of highest priority. RESULTS: During the period of study, 6,431 cases (9.31%) were cancelled out of 69,066 listed cases. Patient no-shows accounted for 62.52% of cancellations. A Pareto analysis showed that around 80% of the known reasons for cancellation after admission were due to a lack of surgical theatre time (30%), incomplete preoperative assessment (21%), upper respiratory tract infection (19%), and high blood pressure (13%). CONCLUSION: This study identified the most common reasons for operation cancellation at a teaching hospital. Potential avoidable root causes and recommended interventions were suggested accordingly. Future research, available resources, hospital policies, and strategic measures directed to tackle these reasons should take priority.

This study sought to determine the prevalence of pathogenic and non-pathogenic bacteria in the oral cavities of children with cancer. There were 68 paediatric patients with cancer who were included in this study. Oral swab samples from the dorsum of tongues and mouth floors of these patients were subjected to culture, staining, and molecular methods to detect the bacteria. The overall prevalence of gram-positive and gram-negative bacteria was 79.4% (54/68; 95% CI = 68.4 – 87.3) and 25% (17/68; 95% CI = 16.2 – 36.4), respectively. Streptococcus salivarius and Streptococcus parasanguinis were the predominant pathogenic grampositive bacteria, while Neisseria subflava and Neisseria perflava were the most common pathogenic gram-negative bacteria. The results revealed that the number of bacteria isolates recovered in patients receiving cancer treatment was higher (55.9%) than those who had not received treatment (16.2%). Therefore, more isolated pathogenic bacteria were observed post-therapy (54.4%). Pathogenic organisms can have significant implications on patient health. Awareness of the types of bacteria inhabiting the oral cavity is essential to predict and prevent dental problems, and their associated systemic complications. Findings on the diversity of oral microflora can also provide a better understanding of the aetiology of oral diseases in paediatric patients receiving cancer treatment.

Mouth rinses which function as breath fresheners, medicaments, and antiseptics can also deliver oral therapeutic agents. This study evaluated and compared the antifungal effects of synthetic and herbal mouth rinses on oral C. albicans and C. glabrata via disk diffusion, minimal inhibition concentration (MIC), minimum fungicidal concentration (MFC), time-kill assay, and growth profile tests. The four chemical mouth rinses, namely Brand O (A), Brand M (B), Brand H (C), and Brand B (D) used in the study showed positive antifungal activity in these two species. The average diameter of the inhibition zones obtained from the disk diffusion test was higher in mouth rinse B (C. albicans = 12.0 ± 0.9 mm, C. glabrata = 13.5 ± 0.8 mm) compared to those in C, A and D. Both Candida species exhibited similar MIC and MFC values, ranging from 1.63 ± 0.5 to 18.75 ± 0.0 µg/mL and 6.51 ± 2.01 to 50.00 ± 9.36 µg/mL, respectively. These synthetic mouth rinses had efficient killing activity eliminating 50% of the growing population of both Candida spp. following 15 seconds exposure time. Analyses of the growth profile curves showed that mouth rinses B and A resulted in rapid growth depletion of both Candida spp. Meanwhile, three herbal mouth rinses, namely Brand S (E), Brand C (F), and Brand P (G), were less effective against C. albicans and C. glabrata. Mouth rinses B and A contained cetylpyridinium chloride and chlorhexidine, respectively, and could be an effective alternative for controlling and preventing oral candidiasis.
