Measurements of three-dimensional glenoid erosion when planning the prosthetic replacement of osteoarthritic shoulders
Authors: Terrier A. , Ston J. , Larrea X. , Farron A. 
Published: April 2014

The three-dimensional (3D) correction of glenoid erosion is critical to the long-term success of total shoulder replacement (TSR). In order to characterise the 3D morphology of eroded glenoid surfaces, we looked for a set of morphological parameters useful for TSR planning. We defined a scapular coordinates system based on non-eroded bony landmarks. The maximum glenoid version was measured and specified in 3D by its orientation angle. Medialisation was considered relative to the spino-glenoid notch. We analysed regular CT scans of 19 normal (N) and 86 osteoarthritic (OA) scapulae. When the maximum version of OA shoulders was higher than 10°, the orientation was not only posterior, but extended in postero-superior (35%), postero-inferior (6%) and anterior sectors (4%). The medialisation of the glenoid was higher in OA than normal shoulders. The orientation angle of maximum version appeared as a critical parameter to specify the glenoid shape in 3D. It will be very useful in planning the best position for the glenoid in TSR.Cite this article: Bone Joint J 2014;96-B:513–18.

Published: April 2014

We report the short-term follow-up, functional outcome and incidence of early and late infection after total hip replacement (THR) in a group of HIV-positive patients who do not suffer from haemophilia or have a history of intravenous drug use. A total of 29 patients underwent 43 THRs, with a mean follow-up of three years and six months (five months to eight years and two months). There were ten women and 19 men, with a mean age of 47 years and seven months (21 years to 59 years and five months). No early (< 6 weeks) or late (> 6 weeks) complications occurred following their THR. The mean pre-operative Harris hip score (HHS) was 27 (6 to 56) and the mean post-operative HHS was 86 (73 to 91), giving a mean improvement of 59 points (p = < 0.05, Student’s t-test). No revision procedures had been undertaken in any of the patients, and none had any symptoms consistent with aseptic loosening. This study demonstrates that it is safe to perform THR in HIV-positive patients, with good short-term functional outcomes and no apparent increase in the risk of early infection.

Published: April 2014

We evaluated the duration of hospitalisation, occurrence of infections, hip dislocations, revisions, and mortality following primary hip and knee replacement in 857 patients with Parkinson’s disease and compared them with 2571 matched control patients. The data were collected from comprehensive nationwide Finnish health registers. The mean follow-up was six years (1 to 13). The patients with Parkinson’s disease had a longer mean length of stay (21 days [1 to 365] vs 13 [1 to 365] days) and an increased risk for hip dislocation during the first post-operative year (hazard ratio (HR) 2.33, 95% confidence intervals (CI) 1.02 to 5.32). There was no difference in infection and revision rates, and one-year mortality. In longer follow-up, patients with Parkinson’s disease had higher mortality (HR 1.94, 95% CI 1.68 to 2.25) and only 274 (34.7%) were surviving ten years after surgery. In patients with Parkinson’s disease, cardiovascular and psychiatric comorbidity were associated with prolonged hospitalisation and cardiovascular diseases also with increased mortality.

Sudden Cardiac Arrest at the Finish Line: In Coronary Ectopia, the Cause of Ischemia Is from Intramural Course, Not Ostial Location
Authors: Joggerst Steven , Monge Jorge , Uribe Carlo , Sherron Scott , Angelini Paolo 
Published: April 2014

A 26-year-old woman, a well-trained runner, had a sudden cardiac arrest just before crossing the finish line of a marathon. She was rapidly resuscitated and was later found to have an ectopic origin of the left coronary artery. This anomaly was surgically repaired by translocating the ostium from the right to the left sinus of Valsalva. Her difficult postoperative course prompted further coronary evaluation, which revealed severe stenosis of the neoostium. The patient underwent a second operation: this time, the stenosis was bypassed via a left internal mammary artery-to-left anterior descending coronary artery (LAD) graft. Hypoplasia of the LAD and spasm during manipulation caused the graft to fail, necessitating double-stent angioplasty of the left main ostium and the LAD 2 months later. At the patient's 6-month follow-up examination, she had no further evidence of functional ischemia, and she resumed jogging.
Because the mode and mechanism of the patient's condition and events were documented in unusual detail, this case furthers our understanding of sudden cardiac arrest in athletes who have rare coronary anomalies. We conclude that ectopia of a coronary artery does not itself cause potentially fatal ischemia. Rather, these events are due to the ectopic artery's intramural proximal course within the aortic media, which might result in critical stenosis by means of hypoplasia or lateral compression of the artery.

Published: April 2014

This prospective cross-sectional study attempted to determine both the usefulness of the serum intercellular adhesion molecule-1 (ICAM-1) as a biomarker for pulmonary artery hypertension secondary to congenital heart disease and the nature of this marker's association with catheter angiographic findings.
Our study included a total of 70 male and female children, comprising 30 patients with both pulmonary artery hypertension and congenital heart disease, 20 patients with congenital heart disease alone, and 20 healthy control subjects. Levels of ICAM-1 in plasma samples from all groups were measured by the enzyme-linked immunosorbent assay method. Cardiac catheterization was also performed in all patients.
The mean serum ICAM-1 levels in pediatric patients who had congenital heart disease with and without pulmonary artery hypertension were 349.6 ± 72.9 ng/mL and 312.3 ± 69.5 ng/mL, respectively (P=0.002). In healthy control subjects, the mean serum ICAM-1 level was 231.4 ± 60.4 ng/mL.
According to the results of this study, the ICAM-1 level of the pulmonary artery hypertension group was significantly higher than those of the congenital heart disease group and the healthy control group. Correlation analysis showed that ICAM-1 level was correlated with systolic and mean pulmonary artery pressures (r=0.62, P=0.001; r=0.57, P=0.001)—which are 2 important values used in diagnosis of pulmonary artery hypertension. Moreover, receiver operating characteristic analysis yielded consistent results for the prediction of pulmonary artery hypertension. Therefore, we conclude that ICAM-1 has potential use as a biomarker for the diagnosis and follow-up of pulmonary artery hypertension.
Infective Endocarditis Caused by Neisseria elongata on a Native Tricuspid Valve and Confirmed by DNA Sequencing
Authors: Yoo Yeon Pyo , Kang Ki-Woon , Yoon Hyeon Soo , Yoo Seungmin , Lee Myung-Shin 
Published: April 2014

Neisseria elongata, a common oral bacterium, has been recognized as a cause of infections such as infective endocarditis, septicemia, and osteomyelitis. Neisseria-induced infective endocarditis, although infrequently reported, typically arises after dental procedures. Without antibiotic therapy, its complications can be severe.
We report the case of a 27-year-old man who presented with fever, severe dyspnea, and a leg abscess from cellulitis. An echocardiogram showed a vegetation-like echogenic structure on the septal leaflet of the patient's native tricuspid valve, and an insignificant Gerbode defect. Three blood cultures grew gram-negative, antibiotic-susceptible coccobacilli that were confirmed to be N. elongata. Subsequent DNA sequencing conclusively isolated N. elongata subsp nitroreducens as the organism responsible for the infective endocarditis. The patient recovered after 21 days of antibiotic therapy. In addition to the patient's unusual case, we discuss the nature and isolation of N. elongata and its subspecies.
Bileaflet versus Posterior-Leaflet-Only Preservation in Mitral Valve Replacement
Authors: Ozdemir Ahmet Coskun , Emrecan Bilgin , Baltalarli Ahmet 
Published: April 2014

In the present study of mitral valve replacement, we investigated whether complete preservation of both leaflets (that is, the subvalvular apparatus) is superior to preservation of the posterior leaflet alone.
Seventy patients who underwent mitral valve replacement in our clinic were divided into 2 groups: MVR-B (n=16), in whom both leaflets were preserved, and MVR-P (n=54), in whom only the posterior leaflet was preserved. The preoperative and postoperative clinical and echocardiographic findings were evaluated retrospectively.
No signs of left ventricular outflow tract obstruction were observed in either group. In the MVR-B group, no decrease was observed in left ventricular ejection fraction during the postoperative period, whereas a significant reduction was observed in the MVR-P group (P=0.003). No differences were found between the 2 groups in their need for inotropic agents or intra-aortic balloon pump support, or in cross-clamp time, duration of intensive care unit or hospital stays, postoperative development of new atrial fibrillation, or mortality rates.
Bileaflet preservation prevented the decrease in left ventricular ejection fraction that usually followed preservation of the posterior leaflet alone. However, posterior leaflet preservation alone yielded excellent results in terms of decreased left ventricular diameter. Bileaflet preservation should be the method of choice to prevent further decreases in ejection fraction and to avoid death in patients who present with substantially impaired left ventricular function.
Functional Fractional Calculus for System Identification of Battery Cells
Authors: Eckert Marius , Kupper Martin , Hohmann Sören 
Published: April 2014

Abstract
This paper considers a fractional modelbased identification method with the objective to determine the aging of a battery cell. The method avoids lumped approximations of the fractional operator. Moreover with this approach it is possible to identify physically motivated battery cell parameters. The basic idea is to transfer the derivatives from the measurements to the so called modulating functions. With the help of simulations a robust behavior against measurement noise is shown. It is possible to use the method for online battery identification.

What is the total Betti number of a random real hypersurface?
Authors: Gayet Damien , Welschinger Jean-Yves 
Published: April 2014

Abstract.

We bound from above the expected total Betti number of
a high degree random real hypersurface in a smooth real projective manifold.
This upper bound is deduced from the equidistribution of critical points of
a real Lefschetz pencil restricted to the complex domain of such a random hypersurface, equidistribution which we first establish. Our proofs involve Hörmander's theory of peak sections as well as the formula of Poincaré–Martinelli.

Published: April 2014

Abstract
Catalytic quantities (2 mol%) of a complex of cobalt containing guanidine and 2,6-pyridinedicarboxylic acid ligands (PDAG-Co) were used for the efficient three-component Mannich reactions of tetrahydro-4-pyranone (1) with different aromatic aldehydes and aniline derivatives in a one-pot process. Reactions rapidly gave high yields of the corresponding three-substituted tetrahydro-4-pyranones at room temperature. Spectroscopic and X-ray analyses support the formation of anti diastereomers as the major or sole products of the reactions.

Preventive effects of the methanol soluble fraction of Millettia macrophylla Benth (Fabaceae) on an osteoporosis-like model of ovariectomized Wistar rats
Authors: Zingue Stéphane , Njamen Dieudonné , Mvondo Marie Alfrede , Magne Nde Chantal Beatrice 
Published: April 2014

Abstract

Background: Millettia macrophylla Benth is a Cameroonian medicinal plant traditionally used to alleviate menopause-related problems. The methanol soluble fraction of this plant was shown to exhibit estrogenic effects in vitro in Human Embryonic kidney cells, and in vivo on ovariectomized rat following the classical uterotrophic assay. Since estrogens have been involved in bone remodeling process, the present study then aimed at evaluating bone loss preventive effects of the methanol soluble fraction of Millettia macrophylla (MM-met) in ovariectomized rat model.

Methods: Twenty-five healthy Wistar female rats (3-month-old) were randomly assigned to a sham-operated group and to four treated ovariectomized (OVX) groups. Treatments lasted 8 weeks and animals were sacrificed. The uterus, the femoral and the tibia bones of each animal were collected, weighed and fixed in 10% formalin for histological analysis.

Results: Results showed that ovariectomy decreased uterine wet weight (p<0.01), induced body weight gain (p<0.01), decreased both femoral and tibia bone density and mineral content and increased alkaline phosphatase activity (p<0.05). E2V and MM-met treatments in general prevented bone mass loss and/or bone density loss. At all tested doses, MM-met induced a significant decrease of alkaline phosphatase activity (p<0.05). As observed with E2V, MM-met also induced a significant protective effect on bone, and this was indicated by an abundance of bone marrow in an almost intact trabecular network.

Conclusions: The overall results show that the methanol soluble fraction of Millettia macrophylla may prevent ovariectomy-induced bone mass loss and deterioration of the trabecular microarchitecture.
Experimental rapid surface heating by induction for injection molding of large LCD TV frames
Authors: Nian Shih-Chih , Lien Che-Wei , Huang Ming-Shyan 
Published: April 2014

Abstract
The use of electromagnetic induction heating on achieving high mold temperature has been proven to effectively improve the appearance quality of injection molded parts. However, until now, the method has only successfully been used on heating small mold surfaces. This study aims to apply the method on a large injection mold that is used for producing 42-inch LCD TV frames. With the goals of achieving heating efficiency and uniformity, the main focus in this research is designing the induction coil. Initially, three types of induction coils – a single-layered coil with currents that flow in one direction, a single-layered coil with currents that flow in opposite directions, and a two-layered coil – were compared to confirm their heating rates; the best one was then chosen. Additionally, evaluation of various induction coils was preceded with commercial simulation software that supports electromagnetic and thermal analyses. An experiment involving heating a simple workpiece with a heated area similar to that of the male mold plate of the LCD TV frames was conducted to confirm its heating rate and uniformity. Real injection molding LCD TV frames assisted with induction heating was then carried out. Experimental results depicted that: (1) a single-layered coil with currents that flow in one direction performed best; (2) that it heated the simple workpiece at a high heating rate of 5.5°C/s with reasonable temperature uniformity (standard deviation: 5.1°C); and (3) induction heating of a 42-inch LCD TV frame mold surface in practical injection molding provided a high heating rate of 4.5°C/s with favorable temperature uniformity (standard deviation: 4.0°C).
French adverbial clauses, rescue by ellipsis and the truncation versus intervention debate
Authors: Authier J.-Marc , Haegeman Liliane 
Published: April 2014

AbstractThis paper investigates the restrictions on movement to the left periphery found in non-root environments such as French central adverbial clauses and argues that an analysis of main clause phenomena based on intervention/Relativized Minimality is to be preferred to one based on structural truncation. The empirical basis for this claim consists of an examination of some asymmetries between French infinitival TP ellipsis and infinitival TP Topicalization. Adopting Authie's (2011) approach to TP ellipsis whereby the to-be-elided TP undergoes fronting in the computational component but fails to be spelled out at PF, we argue that these asymmetries follow from the fact that in French, while a spelled out fronted TP is an intervener for

Published: April 2014

OBJECTIVES:
The current Australian epidemiology of Kawasaki disease (KD) is poorly defined. Previous enhanced surveillance (1993–1995) estimated an incidence of 3.7/100 000 &lt;5 years.

METHODS:
We identified all patients hospitalized in Western Australia (current population ∼2.4 million) 1979 through 2009 with a discharge diagnosis of KD. We reviewed demographic, clinical, laboratory, and echocardiographic data from individual patient files and derived age-specific population estimates. KD diagnosis was made using standard criteria.

RESULTS:
There were 353 KD cases, with incomplete KD in 34 (9.6%). Male to female ratio was 1.7:1 and median age was 3.8 years (interquartile range 12–60 months). Fifty (18.1%) patients were Asian. Mean annual incidence increased from 2.82 per 100 000 children aged &lt;5 years (95% confidence interval, 1.93–3.99) in 1980 to 1989, to 7.96 (6.48–9.67) in 1990 to 1999, to 9.34 (7.72–11.20) in 2000 to 2009. The highest incidence was 15.7 in 2005. A total of 293 children (83%) received intravenous immunoglobulin and 331 (95.4%) aspirin. Of 282 children who completed echocardiographic studies, 47 (16.7%) had coronary artery (CA) ectasia/dilatation and 19 (6.8%) had CA aneurysms; male gender was significantly associated with CA abnormalities.

CONCLUSIONS:
KD epidemiology in Western Australia mirrors that of other industrialized, predominantly European-Caucasian populations. The rising incidence likely reflects both improved ascertainment and a real increase in disease burden. The current Australian incidence is threefold higher than previously reported and similar to the United Kingdom. The CA outcomes, which include the pre-intravenous immunoglobulin era, are comparable to those reported elsewhere.
