We aimed to compare visual and quantitative measurements of breast density and to reveal the density profile with compression characteristics.
Screening mammograms of 1399 women between May 2014 and ...May 2015 were evaluated by using Volpara 4
and 5
version. First 379 mammograms were assessed according to ACR BI-RADS 4
edition and compared to Volpara. We categorized the breast density in two subgroups as dens or non-dens. Two radiologists reviewed the images in consensus. Agreement level between visual and volumetric methods and volumetric methods between themselves assessed using weighted kappa statistics. Volpara data such as fibroglandular volume (FGV), breast volume (BV), compression thickness (CT), compression force (CF), compression pressure (CP) were also analyzed with relation to the age.
1399 mammograms were distributed as follows: 12.7% VDG1, 39.3% VDG2, 34.1% VDG3, 13.9% VDG4 according to the 4th edition of Volpara; 1.2% VDG1, 46% VDG2, 36.8% VDG3, 15.9% VDG4 according to the 5
edition of Volpara. The difference between two editions was 4.7% increase in dense category. 379 mammograms, according to ACR BI-RADS 4
edition, were distributed as follows: 25.9% category A, 50.9% category B, 19.8% category C, 3.4% category D. The strength of agreement between the Volpara 4
and 5
editions was found substantial (k=0.726). The agreements between visual assessment and both Volpara editions were poor (k=-0.413, k=-0.399 respectively). There was a 142% increase in dense group with the VDG 4
edition and 162% with the VDG 5
edition when compared to visual assessment. Compression force decreased while compression pressure increased with increasing Volpara Density Grade (VDG) (p for trend <0.001 for both). Compression thickness and breast volume decreased with increasing VDG (p for trend <0.001 for both). The FGV decreases with age and the breast volume increases with increasing age (p<0.001).
Visual assessment of breast density doesn't correlate well with volumetric assessments. Obtaining additional information about physical parameters and breast profile by the results of quantified methods is important for breast cancer risk assessments and prevention strategies.
Abstract Background Double Balloon Enteroscopy (DBE) provides the opportunity not only to investigate but also apply endoscopic therapeutic interventions for small intestinal disturbances. The aim of ...this study is to assess the indications, diagnosis, therapeutic interventions, complications and safety in clinical practise of DBE procedures that have been performed in our clinic. Material-methods The data of patients who had undergone DBE procedure in our clinic between October 2007 and December 2014 were retrospectively investigated. All features including indications, findings, histopathological results, applied interventions and complications due to procedure were noted. Results A total of 297 patients, 160 (53,9%) male and 137 (46,1%) female were enrolled in the study. Total number of procedures for these 297 patients were 372 256 (68,8%) oral and 116 (31,2%) anal. Mean age of the patients was 46,9 (14–94) years. The most common indications were; obscure gastrointestinal (GI) bleeding (28,3%), iron deficiency anaemia (17,5% ) and abnormal findings in a prior imaging study (13,8%), respectively. The rate of new diagnosis with DBE was 11.8%, where the rate for confirmation of a possible diagnosis was 16.2%, rate of endoscopic treatment with definite diagnosis was 11%, rate for ruling out possible diagnosis or showing normal findings was 34.7% and rate for insufficient or unsuccessful procedures was 26.3%. Ulcers, inflammation and erosions (13%), polyposis syndromes (9.8%) and vascular pathologies (7.4%) were the most common endoscopic findings. Conclusion Our study shows that DBE has high efficacy for diagnosis and ability to perform treatment of small intestinal disturbances with safety.
Although systemic lupus erythematosus (SLE) and autoimmune hepatitis (AIH) are distinct diseases, in clinical practice differentiation of one from other may be difficult. The aim of this study was to ...asses features of SLE in patients with diagnosis of AIH.Thirty patients mean age: 52.4 ± 11.8 years; 23 (76.7 %) female were included in the study. Seven (23.3 %) of the patients full filled 4 or more criteria for classification of SLE. None of the patients had muco-cutaneous lesions characteristic to SLE. Three patients had rheumatoid factor negative arthritis, and 2 patients had pericardial effusion. Four patients had significant thrombocytopenia (<100 × 10
3
/μL), and one of these patients had pancytopenia. None of the patients had hematuria, but 3 patients had proteinuria which did not affect renal function during the study period. One patient died due to pancytopenia-associated pulmonary infection. Among the treated patients with SLE features, 2/5 (40 %) achieved ALT normalization and 9/12 (75 %) of the remaining patients achieved ALT normalization (Fisher’s exact test;
p
= 0.28) during the study period. Although the difference is non-significant, treatment response of AIH patients with SLE features seemed to be delayed and incomplete compared to other patients, but with the limited number of patients it is inconvenient to reach a definitive conclusion. Further studies are needed to identify role of features of SLE on treatment response in patients with AIH.
Hemorrhagic ascites in patients with cirrhosis is described as a RBC (Red Blood cell) > 50,000/mm³ and leads to increased morbidity and mortality. Positive red blood cells at a level of less than ...50,000/mm³ (10,000-50,000) may be encountered in the ascites but it is not known whether this is clinically significant or not. This study aimed to examine the outcome of hemorrhagic ascites in patients with advanced cirrhosis.
Data from 329 cirrhotic patients with ascites who received paracentesis at least once due to ascites was retrospectively analyzed from the period of 2007-2013 from the Türkiye Yüksek İhtisas Hospital, Department of Gastroenterology. Patients were divided according to the number of RBC, with greater than 10,000/mm³ being described as hemorrhagic ascites, and less than 10,000/mm³ described as the normal or control group. Patient data included: number of accepted intensive unit service stays, acute kidney injury (AKI), hepatic encephalopathy (HES), model for end-liver disease (MELD) score, Child Pugh score (CPS), degree of esophageal varices, spleen size and mortality rates.
Patients were defined as having hemorrhagic ascites with a RBC count greater than 10,000/mm³ in 118 (35.9%) patients and as a non-hemorrhagic ascites group with less than 10,000/mm³ in 211 (64.1%) patients. The hemorrhagic ascites group had advanced liver disease symptoms compared to the control group. Meld score in the hemorrhagic group was statistically higher than in the control group (21.5±8.3 vs. 17.3±6.6; p value: 0.001). The median value of bilirubin was 5.9 (0.45-33) in the hemorrhagic ascites group and 4.01 (0.39-33) in the non-hemorrhagic group (p value: 0.001). Using multivariate logistic regression analysis, hemorrhagic ascites was also an independent predictor of mortality (HR 2.7 1.4-6.3), with other mortality indicators being HCC (HR 3.1 1.5-6.4) and HRS (HR 2.6 1.2-5.5).
Patients with hemorrhagic ascites had higher HRS, SBP and admissions to the intensive care unit. We believe that the presence of hemorrhagic ascites can be used as a marker for advanced liver disease and for predicting mortality.
This study aims to show the predictive value of noninvasive serum markers on the hepatic fibrosis level.
This cross sectional study involves 120 patients with chronic hepatitis C. The noninvasive ...markers used were as follows: age-platelet index (AP index), cirrhosis discriminant score (CDS), aspartate aminotransferase (AST)-alanine aminotransferase (ALT) ratio (AAR), fibrosis-4 (FIB-4) index, AST-platelet ratio index (APRI), Goteborg University Cirrhosis Index (GUCI), FibroQ, King's score, platelet count. Concurrent liver biopsies were evaluated using the modified Ishak and Knodell scoring systems. In accordance with the Knodell scores, F3-F4 scores were defined as "severe fibrosis," and the modified Ishak scores stage of ≥3 (F3-F6) were defined as "clinically significant fibrosis." Receiver Operating Characteristic (ROC) curve analyses were carried out to compare the noninvasive markers with hepatic fibrosis level.
Mean age of the patients was 51.7±11.6. A total of 10 patients (8.3%) with Knodell scores and 24 patients (20%) with modified Ishak scores were evaluated to have ≥F3 hepatic fibrosis. ROC analyses with the Knodell and modified Ishak scores were as follows: AP index=0.61-0.57, CDS=0.66-0.55, AAR=0.60-0.49, FIB-4=0.70-0.68, APRI=0.67-0.72, GUCI=0.66-0.72, FibroQ=0.64-0.54, King's score=0.68-0.54, platelet count=0.61-0.55.
We found that APRI, FIB-4, King's score, and GUCI can be used to determination patients with mild fibrosis with a high negative predictive value and in the differentiation of severe/significant fibrosis from mild to moderate fibrosis.
Introduction: Cicatricial alopecia (CA) is a group of disorders that lead to permanent hair loss due to irreversible damage to hair follicles. The aim of this study is to examine clinical and ...demographic characteristics of patients diagnosed with primary lymphocytic cicatricial alopecia (PLCA).Methods: Patients admitted to our outpatient clinic between 2000 and 2010 and who were diagnosed with PLCA were retrospectively evaluated for demographic characteristics, dermatologic findings, personal and family history, histopathologic results, therapeutic options given to the patients, and patient responses to the treatments.Results: Thirty-six patients were included in this study. Histopathological examination of scalp hair samples revealed that findings were concordant with lichen planopilaris (LPP) in 26 patients, discoid lupus erythematosus (DLE) in 7 patients, pseudopelade de Brocq (PB) in 3 patients. The main first-line treatment most commonly reported was intralesional corticosteroid injection (ILCS, n=16, 44.4%), which was followed by hydroxychloroquine (n=10, 28%). Nineteen of the 36 patients responded to the first-line treatments, whereas 17 patients needed another treatment. Treatments that patients were most likely to respond to were hydroxychloroquine and ILCS for LPP patients; hydroxychloroquine for DLE patients; hydroxychloroquine, systemic corticosteroid, and topical corticosteroid treatments for PB patients.Conclusion: PLCA is an entity widely observed in middle-aged women and is mostly encountered in the form of LPP. In the current study, patients most likely benefited from ILCS and hydroxychloroquine treatments.
Abstract
Background
(Pegylated) Interferon (PegIFN) therapy leads to response in a minority of chronic hepatitis B (CHB) patients. Host genetic determinants of response are therefore in demand.
...Methods
In this genome-wide association study (GWAS), CHB patients, treated with (Peg)IFN for at least 12 weeks ± nucleos(t)ide analogues within randomized trials or as standard of care, were recruited at 21 centers from Europe, Asia, and North America. Response at 24 weeks after (Peg)IFN treatment was defined as combined hepatitis B e antigen (HBeAg) loss with hepatitis B virus (HBV) DNA <2000 IU/mL, or an HBV DNA <2000 IU/mL for HBeAg-negative patients.
Results
Of 1144 patients, 1058 (92%) patients were included in the GWAS analysis. In total, 282 (31%) patients achieved the response and 4% hepatitis B surface antigen (HBsAg) loss. GWAS analysis stratified by HBeAg status, adjusted for age, sex, and the 4 ancestry components identified PRELID2 rs371991 (B= −0.74, standard error SE = 0.16, P = 3.44 ×10–6) for HBeAg-positive patients. Importantly, PRELID2 was cross-validated for long-term response in HBeAg-negative patients. G3BP2 rs3821977 (B = 1.13, SE = 0.24, P = 2.46 × 10–6) was associated with response in HBeAg-negative patients. G3BP2 has a role in the interferon pathway and was further examined in peripheral blood mononuclear cells of healthy controls stimulated with IFNα and TLR8. After stimulation, less production of IP-10 and interleukin (IL)-10 proteins and more production of IL-8 were observed with the G3BP2 G-allele.
Conclusions
Although no genome-wide significant hits were found, the current GWAS identified genetic variants associated with (Peg)IFN response in CHB. The current findings could pave the way for gene polymorphism-guided clinical counseling, both in the setting of (Peg)IFN and the natural history, and possibly for new immune-modulating therapies.
Clinical Trials Registation
NCT01401400.
This large multi-ethnic genome-wide association study (GWA) study identified single-nucleotide polymorphisms PRELID2 and G3BP2 associated with both short-term and long-term response to (pegylated) interferon in hepatitis B e antigen (HBeAg)-positive and HBeAg-negative chronic hepatitis B patients, respectively. If further corroborated, these single-nucleotide polymorphisms could aid in clinical counselling.
