Reducing Catheter-associated Urinary Tract Infections via Cost-saving Diagnostic Stewardship.

We conducted a quality improvement project at our large, public, tertiary-care, academic hospital to reduce the standardized infection ratio (SIR) of hospital-acquired catheter-associated urinary tract infections (CAUTIs). Our diagnostic stewardship program, based on education and audit and feedback, significantly reduced inpatient urine culture orders and CAUTI SIR.

EUS-guided fine-needle core liver biopsy sampling using a novel 19-gauge needle with modified 1-pass, 1 actuation wet suction technique.

BACKGROUND AND AIMS: EUS-guided fine-needle core biopsy sampling is a safe and effective technique for diagnosis of focal liver lesions. However, data are limited in its role in parenchymal disease. We evaluated the utility of EUS-guided parenchymal liver biopsy sampling with a modified 1-pass wet suction technique (EUS-modified liver biopsy sampling [EUS-MLB]) in patients with unexplained increase in liver-associated tests. METHODS: We retrospectively evaluated the safety and efficacy of EUS-MLB in patients referred for EUS to evaluate for biliary obstruction and pancreatic disorders but with associated unexplained liver tests. EUS-MLB was performed during the same session after biliary obstruction was excluded. RESULTS: One hundred sixty-five consecutive patients underwent EUS-MLB. The median age was 52 years (interquartile range [IQR], 42-65). Sixty-eight patients (41%) were men. The median of the maximum intact core tissue length was 2.4 cm (IQR, 1.8-3.5). The median total specimen length (TSL) was 6 cm (IQR, 4.3-8). The median number of complete portal tracts (CPTs) per TSL was 18 (IQR, 13- 24). The mean number of CPTs per sample length was 7.5 cm. Adverse events were uncommon (1.8%) and included abdominal pain and self-limited hematoma. CONCLUSIONS: EUS-guided fine-needle biopsy sampling using a novel 19-gauge core needle with a modified 1-pass 1 actuation wet suction technique (EUS-MLB) is a safe and effective way to evaluate patients with unexplained liver tests abnormalities who are undergoing EUS for exclusion of biliary obstruction.

Quantitative comparison of calcium hydroxide removal by EndoActivator, ultrasonic and ProTaper file agitation techniques: an in vitro study.

Calcium hydroxide (CH) dressing residues can compromise endodontic sealing. This study aimed to evaluate the amount of remaining CH in root canals after mechanical removal by four groups of irrigation techniques including needle irrigation only, ProTaper file, EndoActivator, and ultrasonic file. Fifteen extracted single-rooted teeth were collected and used for all four groups. The samples were firstly prepared by ProTaper rotary instruments, and then sectioned longitudinally through the long axis of the root canals, followed by final reassembling by wires. CH was kept in the canals for 7 days setting. The removal procedure began with 5 mL of 2.5% sodium hypochlorite (NaOCl) followed by 1 mL of 17% ethylenediaminetetraacetic acid and a final irrigation with 5 mL of 2.5% NaOCl solution for all groups. No additional agitation of the irrigant was performed in group 1, while agitation for 20 s between irrigants was done with F2 ProTaper rotary file in group 2, EndoActivator with tip size 25/.04 in group 3 and by an ultrasonic file 25/.02 in group 4. The total activation time was 60 s. The roots were then disassembled and captured by digital camera. The ratio of CH coated surface area to the surface area of the whole canal as well as each third of the canal was calculated. The data were statistically analyzed by one-way ANOVA using post hoc Tukey test. Results showed that none of the four techniques could remove all CH. No significant difference was found between EndoActivator and ultrasonic techniques. However, they both removed significantly more CH than ProTaper and needle irrigation (P=0.0001). In conclusion, the sonic and ultrasonic agitation techniques were more effective in removing intracanal medicaments than the ProTaper rotary file and needle irrigation in all thirds of the canal.

Universal Screening for CCHD in Saudi Arabia: The Road to a 'State of the Art' Program.

Critical congenital heart disease (CCHD) has been defined as structural heart defects that are usually associated with hypoxia in the newborn period and have potential for significant morbidity and mortality early in life. CCHD has been estimated to be present in ∼3 in 1000 live births, including Saudi Arabia. Pulse Oximetry Screening (POS) is a highly specific and moderately sensitive test for detecting CCHD with very low false-positive rates. The Kingdom of Saudi Arabia is among high-income countries with a population of more than 33 million and more than 600,000 annual live births. In 2015, the Universal Screening Program for CCHD using Pulse Oximetry was approved in Saudi Arabia. It is expected that any new national program will undergo a learning curve and face many challenges. We believe that developing countries may face different challenges during implementation of such national projects, but the success achieved by Saudi Arabia in implementing the program was mainly due to good preparation before launching the project and advancements in the use of the technology involved in this project. Since starting the universal CCHD screening in 2016, more than 900,000 babies have been screened in Saudi Arabia and many lives have been saved using this safe, non-invasive, inexpensive, and reasonably sensitive test.
