ABSTRACT

Purpose
To assess what clinical and ultrasound features could be most helpful for discriminating benign from malignant unilocular cysts with solid components in premenopausal women with no signs of ascites or carcinomatosis.

Materials and methods
Retrospective study comprising 91 women with preoperative diagnosis of unilocular-solid cyst that underwent surgical removal. The following variables were assessed: age, complaints at presentation, bilaterality, mean size of the lesion, number of papillary projections, size of solid component, surface of solid component (smooth or irregular), amount of color within solid component (no flow, minimal flow, moderate flow, abundant flow). Definitive histopathological diagnosis was used as gold standard. Multivariate logistic regression analysis was performed to identify which variables were independent predictors of malignancy and their odds ratios (OR).

Results
Malignant lesions had significantly larger tumor size, more number of solid components, larger size of solid component, more frequency of irregular surface in the solid component and more frequent moderate or abundant vascularization within the solid component. Logistic regression analysis identified amount of color (OR: 48.7), solid component's surface (OR: 29.1) and mean size of the lesion (OR: 1.58) as independent predictors for malignancy.

Conclusion
Tumor size, irregular surface and the presence of moderate or abundant color score within the solid component are the features more frequently associated to malignancy in unilocular-solid adnexal cysts in premenopausal women.

Predominant Causes of Metabolic Syndrome in Adolescents vs Adults of Northwest India
Authors: Bhansali Anil , Saini Abhimanyu , Sahni Daisy 
Published: September 2015

ABSTRACT
Prevalence and distribution of metabolic syndrome was studied among 167 adolescents (aged 12—17 years) and 361 adults (aged 18—80 years) of Chandigarh zone of northwest India. Measurements of anthropometric variables, blood pressure, triglycerides (TGs), high-density lipoproteins and fasting blood glucose were taken. The metabolic syndrome was examined using criteria reported by national cholesterol education program adult treatment panel III. The overall prevalence of metabolic syndrome was 9% in adolescents and 40.7% in adults. No gender differences in its incidence were noted in adolescents or adults. In adolescents, the contribution of TGs was highest, high blood pressure and low high-density lipoprotein were of about equal significance as risk factors. The least common risk factors were fasting blood sugar and waist circumference. In adults, abdominal obesity was the most common inconsistent factor among the subjects having metabolic syndrome. Efforts should be made to screen out the metabolic syndrome positive subjects, as it is one of leading risk factors of cardiovascular disease and diabetes mellitus.

Effect of Periodontal Diseases on Pregnancy
Authors: Suri Varun , Singla Rimpi 
Published: September 2015

ABSTRACT
Pregnancy is a unique physiological state that affects almost all the organs, because of changes in the hormonal milieu meant to support the pregnancy. These changes, generally reversible after delivery, are sometimes not without adverse effects. Recent upsurge in the interest in periodontal disease in pregnancy is attributed to association between periodontitis and adverse pregnancy outcome. Periodontal diseases are a group of infections and conditions that cause inflammation of the gingiva and the surrounding structures, which leads to destruction of the supporting tooth structures. Periodontal infections are predominantly caused by Gram-negative bacteriae that induce local and systemic elevations of proinflammatory cytokines. Transient bacteremia that occurs due to high vascularity of the periodontal tissue may lead to direct bacterial invasion of the fetoplacental unit. The release of toxic products incites host's response and triggers an inflammatory response. As a source of subclinical and persistent infection along with the cascade of systemic inflammatory responses and immune-mediated injury, periodontitis puts the pregnancy at high risk. Evidence for and against association between oral diseases and adverse pregnancy outcome comes from cross-sectional studies and a few trials. Like any other association of obstetric outcome with systemic diseases, this one is also a subject of debate. We reviewed the studies providing evidence for and against effect of periodontal diseases on pregnancy. We found that different investigators have used different parameters to define periodontal disease, hence different results. Larger randomized controlled trials with uniform definitions of disease and outcome are needed to arrive at a definite conclusion.

Associations between Periodontal Disease Parameters and Coronary Heart Disease in Greek Adults: A Cross-sectional Study
Authors: Chrysanthakopoulos Nikolaos Andreas , Oikonomou Aggelos Antonios , Chrysanthakopoulos Panagiotis Andreas 
Published: September 2015

ABSTRACT

Aim
Several forms of periodontal disease have been associated with the development of coronary heart disease. The current retrospective study was conducted to investigate the possible relationship between periodontal disease parameters and defined coronary heart disease (CHD) in Greek adult patients.

Materials and methods
The study sample consisted of 880 individuals, 400 males and 480 females, aged 40 to 78 years. Data were collected by means of an interviewer administered questionnaire and an oral clinical examination. Statistical analysis of the questionnaire items was performed by using multiple regression analysis model in order to assess possible associations between coronary heart disease as dependent variable and epidemiological variables, biomarkers and periodontal disease parameters as independent variables.

Results
The occurrence of hypertension (OR = 0.01, 95% CI = 0.09-1.33), high level of triglycerides (OR = 0.08, 95% CI = 0.06-2.27) and total cholesterol (OR = 0.08, 95% CI = 0.07- 1.27), low level of high-density lipoprotein (OR = 0.12, 95% CI = 0.09-3.70) and smoking (OR = 1.83, 95% CI = 0.38-8.88) were significantly associated with the presence of coronary heart disease, whereas the periodontal parameters examined were not associated with the occurrence of it.

Conclusion
No associations were observed between periodontal disease parameters and defined coronary heart disease. However, the recorded associations strengthen the role of hypertension, lipids and smoking as causative risk factors of coronary heart disease.

Sedation of Uncooperative Pediatric Dental Patients
Authors: Ballini Andrea , Cantore Stefania 
Published: September 2015

ABSTRACTThe approach to managing the behavior of children in the dental environment must be based on empathy with a child in order to understand why the child is distressed, anxious or afraid.Any dentist treating children needs a spectrum of behavioral techniques from the simplest—tell and show all the way through to a full general anesthetic. Its use is indicated in specific situations and used only when appropriate.On this basis, the caring dentist discusses with the parent the likely need for various behavioral techniques in the child's management. In this study, we show our experience with oral and nasal sedation in a group of pediatric uncooperative dental patients.How to cite this article: Cantore S, Ballini A, Saini R.

The acquisition of the Dutch discourse particle wel
Authors: Hogeweg Lotte , van Gerrevink Richard 
Published: September 2015

Abstract
Dutch is known for its large inventory of discourse particles. Discourse particles are very frequent and highly important in conversation. Yet, not much research has been conducted on how children acquire them. In this paper we focus on the acquisition of the Dutch discourse particle wel. In earlier work, it was argued that despite the apparent diversity of the different uses of the particle wel, it has a core meaning, namely that it functions as a denial of an implicit or explicit negation in the context. In this paper we show that this core meaning is also reflected in the acquisition pattern of wel by Dutch children. Despite the fact that the overwhelming majority of the occurrences of wel are not used as a response to an explicit negation, children seem to acquire wel as the positive counterpart of niet ‘not’.

Wear behavior of oxidized Ti-48Al-2Cr-2Nb (at. %), Ti-6Al-4V and Cp-Ti under dry and lubricated conditions
Authors: Ramos-Saenz Carlos R. , Sundaram Paul A. 
Published: September 2015

Gamma titanium aluminide (gamma-TiAl) is a titanium alloy which contains no vanadium and appears to have potential for biomedical applications such as joint prostheses. The tribomechanical properties of Ti-48Al-2Cr-2Nb (at. %) (gamma-TiAl) subjected to oxidation in air at 500°C and 800°C were determined by standard wear tests using a hardened stainless steel (SS) pin in a linearly reciprocating mode under both dry and lubricated (Ringer’s solution) media. Similar properties for CP-Ti and Ti-6Al-4V were measured for comparison. The lowest mean mass loss was obtained for oxidized gamma-TiAl alloy indicating excellent wear resistance. The dominant wear mechanism on all the Ti alloy samples was abrasion. The oxidation temperature had a minimal effect on the wear of gamma-TiAl but was significant for the other two alloys.
Housing Market Fundamentals, Housing Quality and Energy Consumption: Evidence from Germany
Authors: Claudy Marius , Michelsen Claus 
Published: September 2015

This study investigates the relationship between regional housing market fundamentals and energy consumption. We argue that dwellings, in particularly rental properties, are not only consumer goods, but also constitute financial market assets. Properties are spatially fixed and traded in regional contexts, where real estate market characteristics like vacancy, income levels, and expectations determine rent and prices, which in turn provide incentives to invest in housing quality. The level of housing quality (e.g. windows, building materials, or heating technology) in turn influences the level of energy consumption. While this view is established in the real estate and urban economics literature, it has only recently found its way into the energy debate. As a result, the relationship between regional housing market fundamentals and energy consumption has received little attention. This study provides a first attempt to address this paucity. Utilizing aggregate data on regional space-heating energy consumption from over 300,000 apartment buildings in 97 German planning regions, the study applies structural equation modeling to estimate the influence of housing market fundamentals on the level housing quality, and subsequently on regional energy consumption. Findings provide first evidence that regional differences in housing market conditions have a significant impact on housing quality and energy consumption. Specifically, the results suggest that carbon abatement programs in buildings should focus on regions with weak housing market fundamentals, as market incentives are unlikely to incentivize investors to invest in housing quality attributes. The authors conclude by highlighting important implications for energy research and avenues for further investigations.
Agressie in de tram

Agression on the tram. Perspectives of tram conductors
In this article we focus on how tram drivers react when confronted with a situation of aggression in the tram. Their role in these situations has hardly been explored in recent Dutch studies on this topic. In our explorative research, which consisted of observation and interviews in The Hague, our aim is to gain the perspective of tram drivers on aggressive passengers. Through their eyes we describe a range of strategies which they use to restore public order. Our research shows that in order to understand the reaction of tram drivers a) this has to be placed in the sequential development of an aggressive interaction and b) this has to be related to the ways they give meaning to the aggression of passengers and their work context. Our research shows that there are two perspectives among tram drivers: a) a ‘business’ perspective, with an emphasis of tram drivers as employees who avoid risk situations and call for support in situations they cannot control and b) a personal perspective, in which tram drivers tend to follow more personal guidelines, in which masculinity plays a central role. Those who use the later perspective become more involved in violent and physical interactions.

Underutilization of Meta-analysis in Diagnostic Pathology
Authors: Kinzler Michael , Zhang Lanjing 
Published: September 2015

Context
No studies to our knowledge have investigated citations and utilization of meta-analysis in diagnostic pathology (DP).

Objective
To characterize meta-analyses in DP compared with meta-analyses in medicine.

Design
We searched PubMed for meta-analyses in 12 major DP journals without specifying years and in 4 major medicine journals in both 2006 and 2011. We compared articles' adjusted citation ratios (ACRs), defined as an article's citation count divided by the mean citations for the meta-analysis, review, and original research articles published in the same journal in the same year.

Results
Forty-one of 76 DP articles, 74 of 125 medicine articles in 2011, and 52 of 83 medicine articles in 2006 were qualified meta-analyses as identified by PubMed. The ACRs of DP meta-analysis articles were higher than those of original research articles (2.62 ± 2.31 versus 0.92 ± 0.84, P &lt; .001) and similar to those of review articles in 2006 (2.62 ± 2.31 versus 1.95 ± 1.59, P = .50), but they were similar to both in 2011 (1.85 ± 1.39 versus 0.99 ± 1.43, P = .11; 1.85 ± 1.39 versus 1.12 ± 1.43, P = .21, respectively). Diagnostic pathology and medicine meta-analyses had similar ACRs (1.85 ± 1.39 versus 1.57 ± 1.35 in 2011, P = .60; and 2.62 ± 2.31 versus 1.85 ± 1.90 in 2006, P = .50, respectively). However, although DP journals published fewer meta-analyses (0.97% versus 6.66% in 2011 and 0.67% versus 4.40% in 2006, P &lt; .001 for both), they published more meta-analyses using both original and published data than medicine (21.95% versus 1.59%, P &lt; .001). They also published more meta-analyses per year in 2011–2014 than in 2000–2010 (6.4 ± 1.29 versus 1.36 ± 1.03 articles per year, P &lt; .001).

Conclusions
We found underutilization of meta-analyses in DP, despite their high ACRs and recently increased utilization. More DP meta-analyses are needed.
Accuracy and Adequacy of Computed Tomography–Guided Lung Biopsies: Experience From a Community Hospital
Authors: Florentine Barbara D. , Helton Richard J. , Mitchell Michael M. , Schmidt Kara E. , Kozlov David B. 
Published: September 2015

AbstractContext: Small tissue biopsies obtained through minimally invasive methods have become the primary diagnostic tools for the pathologic characterization and testing of lung masses. In view of recent advances in targeted therapy for non–small cell lung carcinoma, and lung adenocarcinoma in particular, pathologists are now expected to thoroughly characterize lung lesions microscopically while making certain that enough tissue remains for potential molecular analysis if indicated.Objective: To report our experience with computed tomography (CT)–guided lung needle biopsies with particular concentration on diagnostic yield, diagnostic accuracy, and adequacy of tissue for molecular testing if indicated.Methods: A retrospective observational study analyzed 224 biopsies in 222 patients undergoing CT-guided lung needle biopsies. Accuracy of diagnosis and adequacy of tissue for molecular testing, if applicable, was evaluated. A standardized protocol for specimen evaluation, triage, and processing was used. This protocol included intraprocedural real-time microscopic specimen evaluation and triage by a pathologist and use of a histologic protocol specifically designed to conserve tissue for ancillary testing. The initial biopsy was considered successful if the specimen was malignant, had specific benign features, or had nonspecific benign features with follow-up supporting benign lesion. Initial biopsy failure cases were those with inadequate tissue or a nonspecific result with highly suspicious imaging or clinical findings.Results: Of the 224 biopsies, 8 cases with benign but nonspecific findings lacked follow-up and were excluded from the study. The biopsy was diagnostically successful in 189 of 216 (88%) cases. Of these 189 cases, 154 (81%) were malignant, and 35 (19%) were benign. There were 28 diagnostic failures. Subsequent tissue sampling of 13 of 28 diagnostic failures found 9 (69%) to be malignant. Molecular studies were requested on 25 cases: 24 had sufficient material for some of the requested tests, and 20 had enough tissue for all requested testing.Conclusion: A standardized protocol and team approach for CT-guided lung needle biopsy optimizes the ability to achieve a high accurate diagnostic yield with adequate tissue for molecular testing.

Published: September 2015

Abstract
Tears of the peroneus longus muscle are unusual, and typically involve the distal insertion at the musculotendon junction. Although tears of the mid-portion of the peroneus longus muscle/tendon complex have been reported, no reports of a tear at the origin of the peroneus muscle have been published, to the authors’ knowledge. Herein a case of proximal peroneus longus muscle tear and its subsequent management with platelet rich plasma is reported.
Correlation between Poynting flux and soft electron precipitation in the dayside polar cap boundary regions

Published: September 2015

AbstractObservations have revealed large Poynting flux and soft electron precipitation around the cusp region, which have strong impacts on the polar ionosphere/thermosphere. Simulations also confirmed that Poynting flux and soft electron precipitation significantly change the neutral density and dynamics around the dayside polar cap boundary regions. However, no detailed study has been conducted to show if they should coincide with each other or not. Our analysis of Defense Meteorological Satellite Program (DMSP) satellite data reveals a complex correlation between them. Poynting flux and soft particle precipitation are coincident in some cases (match cases), but a clear displacement between them can also be identified in others (nonmatch cases). In the 29 cusp crossings from F13 we investigated, the ratio between nonmatch and match cases is close to 1:4. In nonmatch cases, the displacement between the Poynting flux enhancement and soft particle precipitation enhancement can be as large as 1° in geomagnetic latitude.
