69). No statistical difference (p = 0.051) was noted in the mean stone diameter as measured by clinical CT and micro CT. CONCLUSION Dual energy computed tomography using fast kV switching may potentially be developed as a low dose clinical tool for identifying and classifying renal stones in vivo supporting clinical decision-making. RATIONALE AND OBJECTIVES Bronchiectasis (BE) is associated with chronic obstructive pulmonary disease (COPD), but emphysema and small airways disease, main pathologic features of COPD, have been sparsely studied in BE. We aimed to objectively assess those features in smokers with and without radiographic BE and examine its relationships to airflow obstruction and exercise capacity. MATERIAL AND METHODS We measured emphysema and small airways disease on paired inspiratory-expiratory computed tomography (CT) scans with the parametric response map (PRMEMPH and PRMSAD) method in 1184 smokers with and without radiographic BE. PRMSAD and PRMEMPH are expressed as the percentage of lung area. Clinical, spirometry, and exercise capacity data were measured with standardized methods. The differences in PRMSAD and PRMEMPH between subjects with and without radiographic BE were assessed using multivariable linear regression analysis, and their associations with FEV1 and six-minute walk test (6MWT) were assessed with generalized linear models. RESULTS Out of 1184 subjects, 383 (32%) had radiographic BE. PRMEMPH but not PRMSAD was higher in subjects with radiographic BE than those without radiographic BE in adjusted models. Subjects with radiographic BE and PRMEMPH (defined as ≥5% on paired CTs) had lower FEV1 (least square mean, 1479 mL vs. 2350 mL p less then 0.0001) and 6MWT (372 m vs. 426 m p = 0.0007) than those with radiographic BE alone in adjusted models. CONCLUSION Smokers with radiographic BE have an increased burden of emphysema on paired CTs, and those with radiographic BE and emphysema have lower airflow and exercise capacity. INTRODUCTION Shear wave elastography (SWE) uses focused radiation forces without manual compression and is intrinsically not operator dependent. Shear waves travel faster in stiffer tissue and slower in softer tissues. PURPOSE The purpose of this study was to determine the role of SWE, imaging, and point measurements in differentiating idiopathic granulomatous mastitis (IGM) from breast cancer. MATERIAL AND METHODS Data from 168 patients diagnosed with breast cancer (n= 80) or IGM (n = 88) through image-guided biopsy were included in the study. All patients were evaluated with SWE followed by conventional ultrasonography (US). Shear wave velocity (Vs) and the SWE scoring system (Tsukuba) were used to evaluate lesions, which were classified synchronously according to the Breast Imaging Reporting and Data System (BI-RADS) by using conventional US. Lesion size and BI-RADS scores were recorded, and the scores of the lesions were compared between the two groups. The diagnostic capacity of the Vs value was measuredumber of unnecessary biopsies. Ovulation resumes as quickly as 21 days after birth in a non-fully breastfeeding woman. Traditionally, contraceptive services have been offered 6 weeks post-partum. This is far from ideal and results in unnecessary abortions or inadequate birth spacing which both carry an increased risk of morbidity to mother and potential newborn as well as costs to the health care service. It is now clear that contraception should be discussed during the pregnancy so that the method of choice can be offered immediately post pregnancy prior to discharge from hospital. Long acting reversible contraceptive methods such as implants and IUDs are highly effective as they are user-independent. Large studies have demonstrated that they can be safely inserted during the immediate post-partum period with no increase in complication rates. Policy makers should strive to overcome barriers to offering quality post pregnancy contraceptive services. PURPOSE To establish the optimum grading increment which ensured parity between practitioners while maximising clinical precision. METHODS Second year optometry students (n = 127, 19.5 ± 1.4 years, 55 % female) and qualified eye care practitioners (n = 61, 40.2 ± 14.8 years, 52 % female) had 30 s to grade each of bulbar, limbal and palpebral hyperaemia of the upper lid of 4 patients imaged live with a digital slit lamp under 16× magnification, diffuse illumination, with the image projected on a screen. The patients were presented in a randomised sequence 3 times in succession, during which the graders used the Efron printed grading scale once to the nearest 0.1 increment, once to nearest 0.5 increment and once to the nearest integer grade in a randomised order. Graders were masked to their previous responses. RESULTS For most grading conditions less than 20 % of clinicians showed a ≤0.1 difference in grade from the mean. In contrast, more than 50 % of the student graders and 40 % of experienced graders showed a difference in grade from the mean within 0.5 for all conditions under measurement. Student precision in grading was better with both 0.1 and 0.5 grading increments than grading to the nearest unit, except for limbal hyperaemia where they performed more accurately with 0.5 unit increment grading. Limbal grading precision was not affected by grading step increment for experienced practitioners, but 0.1 and 0.5 grading increments were both better than the 1.0 grading increment for bulbar hyperaemia and the 0.1 grading increment was better than the 0.5 grading increment and both were better than the 1.0 grading increment for palpebral hyperaemia. CONCLUSION Although narrower interval scales maximise the ability to detect smaller clinical changes, the grading increment should not exceed one standard deviation of the discrepancy between measurements. Therefore, 0.5 grading increments are recommended for subjective anterior eye physiology grading (limbal, bulbar and palpebral redness). The concept of personalised medicine is likely to revolutionise the treatment of adult obstructive sleep apnoea as a result of recent advances in the understanding of disease heterogeneity by identifying clinical phenotypes, pathophysiological endotypes, biomarkers and treatable traits. click here Children with the condition show a similar level of heterogeneity and paediatric obstructive sleep apnoea would also benefit from a more targeted approach to diagnosis and management. This review aims to summarise the adult literature on the phenotypes and endotypes of obstructive sleep apnoea and assess whether a similar approach may also be suitable to guide the development of new diagnostic and management approaches for paediatric obstructive sleep apnoea.
