Multiple Cerebral Aneurysms in a Patient with Recurrent Cardiac Myxomas
Authors: Stock K. 
Published: January 2017

A 22 year old female presented in 1987 a cardiac myxoma, removed in 1991. In 1992 catheter angiography showed bilateral aneurysms. Conservative treatment was elected. In 2000 recurrence of the myxoma and subsequent removal, prompted new angiography. All aneurysms had decreased in size, some had spontaneously disappeared.

Published: January 2017

Angioplasty and stenting are emerging alternative treatments to endarterectomy for carotid stenosis. The increasing number of procedures performed carries an increased diagnosis rate of associated asymptomatic intracranial aneurysms, resulting in a clinical and therapeutic dilemma, not fully solved in the literature. When an incidental lesion is found, the first question is whether it is necessary to treat it or not? If treatment is decided, the next question is which should be treated first, the intra or the extracranial lesion? We review our experience and the literature and discuss our preferred approach of single-procedure carotid stenting and aneurysm coiling, which we believe is feasible, safe and effective constituting an option when confronted with this difficult therapeutic dilemma.
Unusual Intracranial Stent Navigation through the Circle of Willis in a Patient with Recurrent Basilar Tip Aneurysm during Stent-Assisted Coiling
Authors: Puri A.S. , Erdem E. 
Published: January 2017

We describe a case of unusual Enterprise stent navigation through the Circle of Willis in a patient with a basilar tip aneurysm, left internal carotid artery (ICA) occlusion and previous right ICA stenting. Basilar tip aneurysms are known for their therapeutic challenges, especially when the posterior cerebral arteries (PCAs) are incorporated in the aneurysm neck. This becomes more technically demanding if the vertebral artery does not offer a route for stent navigation. We undertook stent-assisted coiling using the horizontal stenting of posterior cerebral arteries via both the posterior and anterior communicating artery navigation. This was necessary because the vertebral arteries were very tortuous, hence not suitable for stent navigation due to their small size and stenosis at their origin. Another compounding factor was the anatomy of the aneurysm neck in relation to the T-shaped origin of both P1 PCAs from the basilar artery. The right ICA was stented previously and the whole navigation was done through this stented artery as the opposite left ICA was occluded at the bifurcation. In addition, there was no visualized posterior communicating artery (PCOM) on the right side, so following navigation through the anterior communicating artery (ACOM) the left PCOM artery was catheterized to reach the PCAs. After horizontal placement of stent, coiling was performed for the residual aneurysm. The outcome of this intervention revealed successful placement of the Enterprise stent in bilateral posterior cerebral arteries covering the aneurysm. Further coiling of the basilar artery aneurysm was done with a good result. No complication was seen in the angiography suite or later in the course of action. Horizontal stent placement in wide-necked basilar aneurysms can be performed via the PCOM and ACOM arteries.

Published: January 2017

We evaluate and report our clinical and angiographic outcomes associated with stent-assisted coil embolization of wide-necked intracranial aneurysms using the Enterprise stent. One hundred sixty-nine patients diagnosed with 182 wide-necked intracranial aneurysms underwent placement of the Enterprise stent between April 2009 and October 2011. Demographic information, procedural data, procedure-related complications, angiographic results, and clinical outcomes were reviewed and evaluated. Stent deployment was successful in 166 out of 169 procedures (98.2%). Four patients had acute procedure-related complications, including th romboembolism in three patients and aneurysm perforation resulting in the death of one patient. Immediate angiographic results showed complete occlusion in 101 aneurysms (56.4%) and near-complete occlusion in 55 aneurysms (30.7%). Follow-up angiography was performed in 108 patients with 119 aneurysms at a mean of 8.1 months: complete occlusion was observed in 95 aneurysms (79.8%) and near-complete occlusion was found in 12 aneurysms (10.1%). Delayed intra-stent thromboses were observed in two patients, and asymptomatic in-stent stenosis was observed in one patient. Ten aneurysms (8.4%, 10/119) demonstrated recanalization, all of which were subsequently recoiled successfully. Clinical follow-up was obtained for 132 patients at a mean of 11.4 months, out of which 118 (89.4%) had favorable clinical outcomes as determined using a modified Rankin Scale (mRS) ≤1. The rates of procedure-related mortality and permanent morbidity were 0.6% (1/169) and 2.3%(3/132), respectively. This study adds to the current body of evidence supporting the Enterprise stent as an effective and safe tool for the treatment of wide-necked intracranial aneurysms because it results in more complete occlusion and lower complication rates.
Endovascular Treatment of Intracavernous Carotid Aneurysm with Hyperprolactinaemia
Authors: Caldas J.G.M.P. , Cavalheiro S. , Nalli D.R. , Frudit M.E. , Puglia P. 
Published: January 2017

A 42-year-old woman presented with headache, galactorrhoea, marked hyperprolactinemia and normal neurologic examination. CT, MR and MR-angiography showed an intracavernous carotid artery aneurysm with minimal displacement of the pituitary stalk. Treatment by embolisation using GDC coils allowed exclusion of the aneurysm. Galactorrhoea resolved and serum prolactin levels fell to normal after eight months. Follow-up MR showed absence of the aneurysm, although the discrete mass effect persisted, suggesting that hyperprolactinaemia was due to pulsatility.

Authors: Christova I. , Komitova R. 
Published: January 2017

Data from European and American authors concerning azithromycin efficacy in the treatment of Lyme borreliosis appear controversial. The aim of this study is to establish whether azithromycin is applicable to patients with early Lyme borreliosis. In these studies a total of 93 patients with clinically defined erythema migrans were enrolled. Forty-nine of them were treated with doxycycline for 14 days and forty-four received azithromycin for 5 days. Physical examinations and serologic investigations by ELISA and Western blot for positive findings were performed at the first visit and repeated 4–6 weeks, 3, 6, and 12 months after starting treatment. Complete resolution of erythema migrans within 14 days after the start of therapy was found in 42 (85,7 %) of 49 doxycycline-treated and in 39 (88,6 %) of 44 azithromycin-treated patients. Incomplete resolution of erythema migrans and/or persistence of minor symptoms (post-Lyme syndrome) for at least 3 months were detected in 6 (12,2 %) of doxycycline-treated and in 4 (9,1 %) of azithromycin -treated patients. One patient in each group (2 % vs. 2,3 %) showed progression of the disease with later manifestations of Lyme borreliosis. Compared to doxycycline, azithromycin possessed equal efficacy for treatment of early Lyme borreliosis. There was no difference in clinical outcome between the two treatment regimens.

Published: January 2017

Background Intracranial aneurysms may be associated with an underlying arteriopathy, leading to arterial wall fragility. Arterial tortuosity is a major characteristic of some connective tissue disease. Aim To determine whether intracranial aneurysm is associated with an underlying arteriopathy. Methods Using a case-control design, from May 2012 to May 2013, we selected intracranial aneurysm cases and controls from consecutive patients who had conventional cerebral angiography in our center. Cases were patients with newly diagnosed intracranial aneurysm. Controls were patients who had diagnostic cerebral angiography and free of aneurysm. The prevalence of tortuosity, retrospectively assessed according to standard definitions, was compared between cases and controls and, association between tortuosity and some aneurysm characteristics was examined, in cases only. Results About 659 arteries from 233 patients (112 cases and 121 controls) were examined. Tortuosity was found in 57 (51%) cases and 31 (26%) controls (adjusted OR = 2.71; 95%CI, 1.53–4.80). The same trend was found when looking at each tortuosity subtype (simple tortuosity, coil, kink) or at carotid or vertebral territory separately. In contrast, no association between tortuosity and rupture status, aneurysm number or neck size was found. Conclusions Cervical artery tortuosity is significantly associated with intracranial aneurysm, although not related to main aneurysm characteristics. Our results support the presence of an underlying diffuse arteriopathy in intracranial aneurysm patients.
A new measure of skill mismatch: theory and evidence from PIAAC
Authors: Pellizzari Michele , Fichen Anne 
Published: January 2017

Abstract
This paper proposes a new measure of skill mismatch to be applied to the recent OECD Survey of Adult Skills (PIAAC). The measure is derived from a formal theory and combines information about skill proficiency, self-reported mismatch and skill use. The theoretical foundations underling this measure allow identifying minimum and maximum skill requirements for each occupation and to classify workers into three groups: the well-matched, the under-skilled and the over-skilled. The availability of skill use data further permits the computation of the degree of under- and over-usage of skills in the economy. The empirical analysis is carried out using the first round of the PIAAC data, allowing comparisons across skill domains, labour market statuses and countries.

Published: January 2017

The objective of the current study was to determine the effect of hospital volume on outcomes of abdominal aortic surgery for patients older than and younger than 65 years. In order to perform this investigation, information on all adult patients who underwent abdominal aortic surgery in Maryland from 1994 to 1996 ( N = 2,987 patients) in 45 acute care hospitals was obtained. Hospitals were designated as low (< 20/year), medium (20 to 36/year), or high (> 36/year) volume according to the annual number of procedures performed. The relationship of hospital volume and mortality was determined for patients less than or greater than 65 years old. Two separate multiple logistic regression models were used to adjust for patient case-mix in each age category. Of the 2,987 patients, 2,067 (69%) were older than 65 years and 920 (31%) were younger. The crude in-hospital mortality rates according to hospital volume were 2.7% (low), 2.1% (medium), and 2.7% (high) for patients younger than 65 years old ( p = .8). For patients older than 65 years, in-hospital mortality rates were 11.9% (low), 9.9% (medium), and 6.9% (high) ( p = .005). After adjusting for patient case-mix in a multivariate analysis, high hospital volume was associated with a decreased risk of in-hospital mortality for patients older than 65 years (OR 0.57; 95% CI 0.37 to 0.86; p = .008) but not for patients under 65 years old. In conclusion, hospital volume was associated with decreased in-hospital mortality after abdominal aortic surgery only for patients greater than 65 years old. Because of this differential effect, targeting elderly patients for regionalization would achieve most potentially avoidable deaths for this common high-risk surgical procedure.
Targeting Target Shareholders
Authors: Bernhardt Dan , Liu Tingjun , Marquez Robert 
Published: January 2017

We integrate heterogeneity and uncertainty in investor valuations into a model of takeovers. Investors have dispersed valuations, holding shares in firms they value more highly, and a successful offer must win approval from the median target shareholder. We derive the consequences for an acquiring firm’s takeover offer—its size and cash/equity structure—and implications for takeover premia, firm returns, share price dynamics, the probability that a takeover succeeds, and shareholder welfare. We characterize when the acquirer prefers cash offers and when equity offers are best. Our model collectively reconciles various empirical regularities that have proven elusive to explain in one unified framework, and we derive new testable predictions.

Conservative Management of Extensive Iatrogenic Aortic Dissection
Authors: Tam Derrick , Mazine Amine , Cheema Asim , Yanagawa Bobby 
Published: January 2017

AbstractIatrogenic aortic dissection (IAD) is a rare complication of percutaneous coronary interventions (PCI). There are no clear guidelines for IAD management, and limited data are available. Registry data and case series combined with extrapolations from our experience with spontaneous Type-A dissections suggest that very limited dissections are often managed conservatively with coronary stenting of the entry tear when possible, while more extensive dissections are managed surgically. We present a case report of a 50-year-old woman who underwent PCI for an ST-elevation myocardial infarction that resulted in an extensive IAD from the ostium of the right coronary artery to the aortic root, ascending aorta, and aortic arch. While the current evidence strongly supports surgical management of such extensive dissection, our patient was successfully managed conservatively with complete resolution according to short-term computed tomography imaging. This case suggests that conservative management may be a reasonable approach for select patients with extensive IAD.
Narrative of the Krueger-Scott Mansion Project: Constructing Newark History
Authors: Singer Katie 
Published: January 2017

Newark, New Jersey’s once proposed Krueger-Scott African-American Cultural Center (KSAACC) tells a story of history, economy, race, built environment, and much more. The Center’s development mirrors other urban stories with regard to race, preservation, urban failure, and memory, while also offering a unique understanding of Newark’s own history. The story of the 1990s Krueger-Scott project adds chapters to urban study as a whole, and to the study of Black cultural sites around the country.The KSAACC was met with and has continued to receive resistance from some of Newark’s citizens as well as local journalists and ultimately the very politicians who had at first supported the idea. The ongoing financing of what seemed to some a less than urgent project in a city that had so many pressing needs at the time became a source of tension and ultimately splintered the community. Matters such as these speak to some larger questions concerning the value and place of public history, oral history, and historic preservation in urban environments. This paper is about the creation of African-American historical knowledge and the ways America sees fit to make it public knowledge.

Instituted in 1933 as the first historical park in the Park Service, Morristown National Historical Park (MNHP) marks a watershed moment in Park history and its involvement in the preservation movement of the early twentieth century. We at NJ Studies invited MNHP to submit the Museums, Archives, Artifacts, and Documents News entry for the Winter 2017 edition of the Journal given this issue’s focus on National Parks and the environment. We were surprised and delighted by their very unexpected and interesting submission, and- without giving too much away- hope you will be as well!

Authors: Cofaru Nicolae Florin , Roman Lucian Ion , Oleksik Valentin , Pascu Adrian 
Published: January 2017

Abstract
This paper proposes an organological approach of one of the components of front suspension, namely anti-roll power link. There will be realized a CAD 3D modelling of this power link. 3D modelling is generalized and there were used the powers of Catia V5R20 software. Parameterized approach provides a high flexibility in the design, meaning that dimensional and shape changes of the semi-power link are very easy to perform just by changing some parameters. Several new versions are proposed for the anti-roll power link body. At the end of the work, it is made a static analysis of the semi-power link model used in the suspension of vehicles OPEL ASTRA G, ZAFIRA, MERIVA, and constructive optimization of its body.

Dual solution of Casson fluid over a porous medium: Exact solutions with extra boundary condition
Authors: Khan Najeeb Alam , Khan Sidra 
Published: January 2017

AbstractIn this article we calculate the exact solution of the steady flow of non-Newtonian Casson fluid, over a stretching/shrinking sheet. The governing partial differential equations (PDEs) are transformed into ordinary differential equation (ODE) by using similarity transformation and then solved analytically by utilizing the exact solution. The closed form unique solution is obtained in the case of stretching sheet whereas for shrinking sheet unique and dual solutions are obtained. Influences of Casson fluid and suction/injection parameter on dimensionless velocity function are discussed and plotted graphically; also the effects of skin friction coefficient are presented in graphical form. Comparisons of current solutions with previous study are also made for the verification of the present study.

Published: January 2017

AbstractBackground:Oxycodone is a narcotic drug widely used to alleviate moderate and severe acute and chronic pain. Variability in analgesic efficacy could be explained by inter-subject variations in plasma concentrations of parent drug and its active metabolite, oxymorphone. To evaluate patient compliance and to set up therapeutic drug monitoring (TDM), an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) assay was developed and validated for the parent drug and its major metabolites noroxycodone and oxymorphone.Methods:Extraction of analytes from plasma and urine samples was obtained by simple liquid-liquid extraction. The chromatographic separation was achieved with a reversed phase column using a linear gradient elution with two solvents: acetic acid 1% in water and methanol. The separated analytes were detected with a triple quadrupole mass spectrometer operated in multiple reaction monitoring (MRM) mode via positive electrospray ionization (ESI).Results:Separation of analytes was obtained in less than 5 min. Linear calibration curves for all the analytes under investigation in urine and plasma samples showed determination coefficients (rConclusions:Rapid extraction, identification and quantification of oxycodone and its metabolites both in urine and plasma by UHPLC-MS/MS assay was tested for its feasibility in clinical samples and provided excellent results for rapid and effective drug testing in patients under oxycodone treatment.

Fractal Based Triple Band High Gain Monopole Antenna
Authors: Pandey Shashi Kant , Pandey Ganga Prasad , Sarun P. M. 
Published: January 2017

AbstractA novel triple-band microstrip fed planar monopole antenna is proposed and investigated. A fractal antenna is created by iterating a narrow pulse (NP) generator model at upper side of modified ground plane, which has a rhombic patch, for enhancing the bandwidth and gain. Three iterations are carried out to study the effects of fractal geometry on the antenna performance. The proposed antenna can operate over three frequency ranges viz, 3.34–4.8 GHz, 5.5–10.6 GHz and 13–14.96 GHz suitable for WLAN 5.2/5.8 GHz, WiMAX 3.5/5.5 GHz and X band applications respectively. Simulated and measured results are in good agreements with each others. Results show that antenna provides wide/ultra wide bandwidths, monopole like radiation patterns and very high antenna gains over the operating frequency bands.
