Abstract Background Patients requiring maintenance hemodialysis (HD) are at increased risk of bloodstream infections. We investigated a cluster of infections due to unusual Gram-negative bacilli that affected patients undergoing HD at an outpatient unit with 19 stations (Clinic A). Methods A case was defined as a HD patient at Clinic A with >1 blood or urine culture positive for Delftia acidovorans, Enterobacter absuriae, or Burkholderia cepacia during the period February 1 – April 30, 2018. An investigation included review of patient records, facility policies, practice observation, environmental cultures, and a 1:4 case–control study. Controls were patients without bloodstream infection (BSI) during the outbreak period. Results The cluster included 3 patients. Patient 1 had BSI due to D. acidovorans (2/08), E. absuriae (3/15) and B. cepacia (3/17). Patient 2 had BSI due to D. acidovorans (3/17 and 3/27) and S. maltophilia (4/5). Patient 3 had a urine culture positive for D. acidovorans and S. maltophilia (4/2). The case–control study showed that cases had been dialyzed more often than controls on the third shift (P < 0.0001) and at station 2 (P < 0.0001), where subsequently a wall box spent dialysate drain connection swab culture yielded D. acidovorans. E. absuriae was recovered from wall boxes and spent dialysate drain connection at two stations and from used prime buckets from two stations; one wall box culture grew S. maltophilia. D. acidovorans and E. absuriae patient isolates were not available for genomic analysis. Observations revealed that waste water was leaking onto the floor from several wall boxes, and that priming buckets were often rinsed with tap water after being disinfected with 1:100 bleach solution and not allowed to dry before reuse. Multiple deficiencies in hand hygiene and station disinfection were observed. No deficiencies in water treatment practices were identified. Multiple water cultures obtained in August were negative for the observed pathogens. Conclusion A cluster of unusual Gram-negative infections in outpatient HD patients was most likely due to exposures to contaminated wall boxes or priming buckets; poor hand hygiene and station disinfection can contribute to transmission to patients.

The aim is to investigate the dental development (DD) in children with hypodontia and hyperdontia compared to age, gender, and race matched controls.A match-pair case control study was conducted among children aged 5 to 14-year-old, attending the Dental Polyclinic, IIUM, from December 2011 until September 2014. Willem’s method was used to analyze the dental age (DA) using panoramic radiograph. The difference between dental age of hypodontia/hyperdontia children and the controlswas analyzed using analysis of covariance (ANCOVA). The differences between dental and chronological ages (CA) and the differences in DA and CA with the numbers of missing teeth were analyzed using t-test. Intra-class correlation coefficient between examiners ranged from 0.98-0.99. The result is that27 hypodontia and 12 hyperdontia samples were recruited and compared to a total of 78 matched controls. Both male (n=12) and female (n=15) hypodontia children had statistically significant delay in DD (p=0.000). There was no significant difference in the DD of male (n=7, p=0.811) and female (n=5, p=0.235) in hyperdontia children compared to the matched controls. No differences were observed between DA and CA with the number of missing teeth. Unlike hyperdontia children, hypodontia children showed delayed DD in comparison to age, gender, and race matched controls. There was no association between magnitudes of dental development delay in hypodontia children with the number of missing teeth. This study provides valuable baseline information for provision of better treatment planning for those hypodontia and hyperdontia children that may involve inter-disciplinary management.

Introduction: Some assumptions have been made on the probable association between fever and pyuria. Objectives: The present study aimed to investigate the association between fever and pyuria. Patients and Methods: In this case-control study, 90 febrile and 90 non-febrile children aged more than one month who were admitted to the pediatric ward were included. Urine specimens of children less than 2 years of age were collected by urine bag. Midstream urine samples were collected and immediately sent to the laboratory for complete urinalysis and urine culture. Results: Overall, 6.7% in febrile children and 2.2% in control group had pyuria however there was no significant association between fever and pyuria (P>0.05). Additionally, no association between the presence of pyuria and type of disease was detected (P>0.40). Conclusion: The present study could not reveal any association between fever and pyuria in children older than one month.
