At 3 and 4 mm, all of the experimental groups had significantly higher levels of smear layer formation than the control group. At 2 mm, the level of smear layer formation in the UA group was significantly higher than that of the control group, and there were no significant differences among the EC, ED, and control groups. At 1 mm, there were no significant differences between the ED and control groups, and the levels of smear layer formation in the EC and UA groups were significantly higher than that of the control group. There were no significant differences between the ED and EC groups at any of the apical levels. Conclusion The smear layer formation occurred in all the specimens submitted to final irrigation, irrespective of the technique used.Four patients undergoing contrast-enhanced CT scanning have been infected with hepatitis C virus from a contaminated multi-dose NaCl vial. The outbreak occurred probably due to safe injection practices breach resulting in the contamination of a multi-dose NaCl vial. Not all patients exposed to the same multi-dose NaCl have been infected. The uneven distribution of infections could possibly be attributed to a stochastic effect of a low infectious dose. This implies that outbreak investigations need to be extended to all patients scheduled before and after the first identified infected patient to definitely confirm or rule out a nosocomial transmission.The transmission behaviour of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still being defined. It is likely that it is transmitted predominantly by droplets and direct contact and it is possible that there is at least opportunistic airborne transmission. In order to protect healthcare staff adequately is necessary that we establish whether aerosol generating procedures (AGPs) increase the risk of transmission of SARS-CoV-2. Where we do not have evidence relating to SARS-CoV-2, guidelines for safely conducting these procedures should consider what risk procedures would have of transmitting related pathogens. Currently there is very little evidence detailing the transmission of SARS-CoV-2 associated with any specific procedures. Regarding aerosol generating procedures and respiratory pathogens in general, there is still a large knowledge gap that will leave clinicians unsure what risk they are putting themselves in when offering these procedures. This review aimed to summarise the evidence (and gaps in evidence) around AGPs and SARS-CoV-2.Background Streptococcus pyogenes is a well-known cause of postpartum infections and is causing significant morbidity and mortality. Aim To describe measures taken to control an outbreak of postpartum infections caused by S. pyogenes emm75 on a maternity ward. Methods Patients presenting postpartum with signs and symptoms of infection were cultured for beta-haemolytic streptococci with cervical swabs and blood cultures, and bacterial isolates were species-determined with MALDI-TOF MS and emm-typed. Pharyngeal swabs were taken from health care workers at the ward. Bacterial isolates were subjected to whole genome sequencing (WGS). The multilocus sequence type and the number of single nucleotide polymorphisms (SNPs) compared to an index genome were determined. Findings During a 3-month period six cases of postpartum infection with S. pyogenes emm75 were identified on the maternity ward. By comparing delivery dates with duty rotas, one health care worker (HCW) was identified as a possible source of infection in five cases. After repeated pharyngeal swabs from this individual an S. pyogenes emm75 was isolated. The five isolates from patients epidemiologically linked to the HCW and the two isolates of the family members had an identical sequence type (ST 49) and 0-2 SNPs difference compared to the HCW isolate, whereas the sixth patient had an unrelated isolate. Eradication antibiotic therapy with clindamycin and rifampicin was given to the carrier. All patients received intravenous antibiotic treatment and recovered. Conclusion A 3-month outbreak was stopped when a carrier was identified and treated. Source identification and WGS proved vital for outbreak-control.Background There is no consensus on the management of spontaneous sternoclavicular joint infection (SCJI). Negative pressure wound therapy (NPWT) has been widely accepted for SCJI. We reviewed our experience with the management of this condition comparing the NPWT vs. NPWT combined with instillation and dwell time (NPWTid). Methods We retrospectively analyzed the data of patients with spontaneous SCJI treated in our thoracic unit. Results From March 2008 to October 2019, 27 patients (21 men and 6 women) underwent NPWT combined with muscle flap transfer following necrosectomy and chest wall resection for SCJI. The median age was 57.1 years (range 35 - 85 years). Depending on the management, the patients were divided into 2 groups; 16 patients with NPWT were included in group 1 and 11 patients with NPWTid were included in group 2. The severity of SCJI, extent of chest wall resection and type of muscle flap were not significantly different (p=0.35, p=0.858, p=0.705, respectively). Median duration of hospital stay and NPWT were shorter in group 2 (30d vs 25d and 20d vs. 16d, respectively). The required wound dressing changes were significantly lower in group 2 (p=0.008). Statistical trend to higher bacterial eradication in group 2 was noted (p=0.093). Postoperative complications including SCJI recurrence, wound seroma and dehiscence were not significantly different between groups (p=0.269). buy XL177A Conclusions The NPWTid appears a useful strategy in patients with SCJI leading to higher incidence of bacterial eradication and shorter wound care.Clinical cases of intracardiac foreign bodies are rarely. We report a case of a sewing needle embedded in the ventricular septum of a patient reporting of chest pain. It was removed under video-assisted thoracoscopic cardiac surgery.Background Tricuspid regurgitation (TR) is associated with poor outcomes following cardiac surgery. Guidelines recommend correction of severe TR in patients undergoing left sided valve surgery but not coronary artery bypass grafting (CABG). We sought to evaluate impact of TR on outcomes following CABG. Methods All patients (n=28,027) undergoing CABG in a regional Society of Thoracic Surgery database (2011-2018) were stratified by TR severity. Primary outcomes included major morbidity or mortality, which were compared using univariate analysis. Results Of patients undergoing CABG, 4,837 (17%) had mild, 800 (3%) had moderate, and 81 (0.29%) had severe TR. Increased severity was associated with higher rate of preoperative heart failure [none 5162 (23.4%) vs mild 1697 (35%) vs moderate 427 (53%) vs severe 54 (67%), p less then 0.0001] and STS predicted risk of mortality [1.0 (0.6-1.9) vs 1.4 (0.8-2.9) vs 2.8 (1.4-5.4) vs 6.2 (2.2-11.4), p less then 0.0001]. Increasing severity was associated with higher postoperative rate of renal failure [426 (1.
