The rates of malignancy for each category and the accuracy of breast FNAB in diagnosing malignancy were calculated. Of the total 487 patients, 120 cases were benign on histology, while 367 were malignant. The rates of malignancy in benign, atypical, suspicious and malignant categories were 5%, 25%, 71%, and 99.7%, respectively. The diagnostic accuracy of atypical, suspicious and malignant categories was calculated as 90.1%, 95.2%, and 93.3%, respectively. The high diagnostic accuracy for each BIRADS category suggest excellent accuracy for Breast FNAB using the IAC Yokohama system.

High-flow arteriovenous fistula (AVF) for haemodialysis leads to profound haemodynamic changes and sometimes to heart failure (HF). Cardiac output (CO) is divided between the AVF and body tissues. The term effective CO (COef) represents the difference between CO and AVF flow volume (Qa) and better characterizes the altered haemodynamics that may result in organ hypoxia. We investigated the effects of Qa reduction on systemic haemodynamics and on brain oxygenation. This is a single-centre interventional study. Twenty-six patients on chronic haemodialysis with high Qa (>1500mL/min) were indicated for surgical Qa reduction for HF symptoms and/or signs of structural heart disease on echocardiography. The included patients underwent three sets of examinations at 4months and then 2days prior and 6weeks post-surgical procedure. Clinical status, echocardiographical haemodynamic assessment, Qa, and brain oximetry were recorded. All parameters remained stable from selection to inclusion. see more After the procedure, Qa decreased from 3.0±1.4 to 1.3±0.5L/min, P<0.00001, CO from 7.8±1.9 to 6.6±1.5L/min, P=0.0002, but COef increased from 4.6±1.4 to 5.3±1.4L/min, P=0.036. Brain tissue oxygen saturation increased from 56±11% to 60±9%, P=0.001. Qa reduction led to increased COef. This was explained by a decreased proportion of CO running through the AVF in patients with Qa>2.0L/min. These observations were mirrored by higher brain oxygenation and might explain HF symptoms and improved haemodynamics even in asymptomatic high Qa patients. 2.0 L/min. These observations were mirrored by higher brain oxygenation and might explain HF symptoms and improved haemodynamics even in asymptomatic high Qa patients. Sensitivities of various sampling methods to detect malignant biliary strictures remain suboptimal. Irrigation during digital single operator cholangioscopy (dSOC) is done routinely for visualization of the duct. The aim of this study was to evaluate improvement of the sensitivity for detecting malignant biliary strictures when adding aspiration fluid cytology (AFC) from the irrigated fluid during cholangioscopy to cholangioscopic biopsy (CBx). We conducted a retrospective analysis of patients at a tertiary medical center who underwent CBx for evaluation of their biliary strictures. We included patients who had aspiration of fluid from the bile duct after CBx and were sent for cytology from January 2017 to October 2017. Diagnosis was made on the basis of final pathology or follow-up over 9 months. Fifty-six patients had CBx obtained, out of which 35 patients had AFC in conjunction. Twenty-two (62%) patients were male and the average age was 65 years. Considering atypical cells as benign, the sensitivity, specificity, positive and negative predictive values (PPV, NPV) for CBx were 62.5%, 100%, 100%, and 76% respectively. When CBx combined with AFC, the above statistics went up to 81.25%, 100%, 100%, and 86.36% respectively. When atypical cells were considered malignant, the sensitivity, specificity, PPV and NPV for CBx were 81.25%, 84.21%, 81.25%, 84.21% and increased to 93.75%, 78.94%, 78.94%, and 93.75% respectively after adding AFC re
