First Results of using Stem Cell Transplantation for Pediatric Patients in Case of Dilated Cardiomyopathy
Introduction. Dilated cardiomyopathy is a serious disorder of the myocardium in pediatric age. Conservative therapy is limited and lethal outcome observed in one third of patients within a year. Bone marrow derived progenitor cell transplantation is becoming a promising method of treatment in adult population and there is ground to believe there are perspectives in pediatric cardiology. Aim of the Study. We present the first results of bone marrow cell transplantation in case of dilated cardiomyopathy for six patients at age four months to seventeen years. Materials and methods. We did the six Bone marrow derived progenitor cell (BMCs) intramycardial transplantations. Five to 30 mililiters of bone marrow were aspirated from iliac bone. Seventeen to 90 million BMCs were isolated and as suspension of physiologic saline given to patients by intramyocardial punction. Every patient underwent repeated examination every two month. Results. Six months following bone marrow derived progenitor stem cell intramyocardial transplantation we observed increase of ejection fraction in 4 patients, decrease of dilatation echocardiographycally and cardiothoracic ratio (CTR) at chest x-ray; decrease of the stage of heart insufficiency clinically from class IV to I-II(NYHA). Conclusions. We see the intramyocardial administration of bone marrow cells proved to be technically feasible and safe, also the procedure does not need for expensive technical equipment. The bone marrow transplantation improves the patients clinical situation and physical measurements. Our method might be used for the stabilization of the patient to get the time for further treatment.

The Concept, Diagnostics, Surgical Prevention and Treatment of Hereditary Colorectal Cancer in Nowadays Medicine
Colorectal cancer is a frequent cause of oncological morbidity and mortality. It is the second most common cancer in Europe (13.0%) almost matching the frequency of lung cancer, the most widespread malignancy (13.2%). In European Union countries colorectal cancer is the most frequent tumour. Colorectal cancer is also the second most common cause of cancer death in Europe accounting for 11.9% of cancer-related mortality (4). In 20% of colorectal cancer patients, genetic background exists. However, the discovered genetic mutations related to high lifetime risk of colorectal cancer account only for 5-6% of colorectal cancer cases (27). The two main hereditary cancer syndromes involving the large bowel are familial adenomatous polyposis, responsible for 1% of the annual colorectal cancer burden, and hereditary non-polyposis colorectal cancer that accounts for 2-3% of colorectal cancer cases (9). Both syndromes are remarkable not only by the scientific novelty in hereditary cancer research but only for high practical significance as the knowledge about the peculiar risk of primary and metachronous colorectal cancer as well as about certain extracolonic malignancies is necessary to plan the surgical intervention correctly.

Diagnosis and Management of the Thyroid Nodules
Thyroid nodules are a common clinical problem. Most of the discovered nodules are benign, however increase in thyroid cancer incidence has been reported. For management of thyroid nodules distinction between benign and malignant thyroid tumors is essential. Thyroid nodule management involves notice to: clinical features, biochemical tests, imaging studies, fine needle aspiration, thyroid scintigraphy and immunocytochemistry. In spite of different combinations of diagnostic tools used, it is still difficult to precisely determine malignant potential of thyroid nodules.

Modified Senning Operation in the Treatment of Transposition of The Great Arteries
The arterial switch operation has become the procedure of choice for patients with transposition of the great arteries(TGA) in most medical centres. Although atrial switching may occasionally be employed in some centres in cases with delayed diagnosis, pulmonary hypertension and some other unusual entities. We preferred to use the atrial switch operation - modified Senning procedure for 6 years 6 months old boy with TGA, small atrial septal defect (ASD) and patent ductus arteriosus (PDA).

Laparoscopic Repair of Paraesophageal Hiatal Hernia in a Newborn
A 3-month old boy was hospitalized with the suspicion of right sided pneumonia. Examination revealed hiatal or paraesophageal hernia. Ultimately, a laparoscopic operation was performed. During the operation, PEHH of the transverse colon with displaced gastro esophageal junction was discovered. Laproscopic hiatal hernia repair with modified Thal fundoplication were performed. Recovery of child 2 years after surgery was uneventful.
Delayed clinical improvement after deep brain stimulation–related subdural hematoma
Authors: Oyama Genko , Okun Michael S. , Zesiewicz Theresa A. , Tamse Tiffany , Romrell Janet , Zeilman Pamela , Foote Kelly D. 
Published: April 2011

Object
The purpose of this paper is to present 4 cases that illustrate the management and outcome of subdural hematoma (SDH) following deep brain stimulation (DBS) lead implantation.

Methods
The authors identified 4 cases of SDH following DBS lead implantation from a pool of 500 consecutive lead implantations (incidence 0.08%) performed at the University of Florida. Cases were characterized by chart review, serial Unified Parkinson's Disease Rating Scale evaluations, and changes on serial postoperative imaging studies.

Results
Two of the 4 patients with DBS-related SDH were clinically symptomatic. In the other 2 cases the SDH was incidentally discovered on routine postoperative lead localization imaging studies. None of the patients required craniotomy for evacuation of the SDH in the acute phase. Three of the 4 cases were managed with bur hole drainage in the chronic phase, and one was successfully managed nonoperatively. In all 4 cases, thresholds for stimulationinduced side effects were lower during initial postoperative programming than during intraoperative macrostimulation. Expected clinical improvement from DBS was achieved without lead revision in all 4 cases, but only after a significant delay.

Conclusions
Subdural hematoma is a rare and potentially avoidable complication of DBS that does not typically mandate acute hematoma evacuation or hardware revision and does not preclude an excellent outcome from DBS therapy. The clinical picture and apparent lead position tend to improve with time, and it may be wise to delay repositioning of an ineffective DBS lead following a hemorrhage until the DBS lead and surrounding brain tissue have settled into their final position and the insulted brain has had sufficient time to recover.
Venous sacrifice in neurosurgery: new insights from venous indocyanine green videoangiography

Published: April 2011

Object
The purpose of this paper is to evaluate whether venous indocyanine green (ICG) videoangiography has any potential for predicting the presence of a safe collateral circulation for veins that are at risk for intentional or unintentional damage during surgery.

Methods
The authors performed venous ICG videoangiography during 153 consecutive neurosurgical procedures. On those occasions in which a venous sacrifice occurred during surgery, whether that sacrifice was preplanned (intended) or unintended, venous ICG videoangiography was repeated so as to allow us to study the effect of venous sacrifice. A specific test to predict the presence of venous collateral circulation was also applied in 8 of these cases.

Results
Venous ICG videoangiography allowed for an intraoperative real-time flow assessment of the exposed veins with excellent image quality and resolution in all cases. The veins observed in this study were found to be extremely different with respect to flow dynamics and could be divided in 3 groups: 1) arterialized veins; 2) fast-draining veins with uniform filling and clear flow direction; and 3) slow-draining veins with nonuniform filling. Temporary clipping was found to be a simple and reversible way to test for the presence of potential anastomotic circulation.

Conclusions
Venous ICG videoangiography is able to reveal substantial variability in the venous flow dynamics. “Slow veins,” when they are tributaries of bridging veins, might hide a potential for anastomotic circulation that deserve further investigation.

Object
Assimilation of the atlas to the occiput may result in symptoms that are often compressive in nature around the outlet of the foramen magnum. The aim of the present study was to elucidate the morphological features of the bone through this foramen.

Methods
Thirteen adult skulls with atlantooccipital fusion underwent morphometrical analysis of the outlet of the foramen magnum.

Results
All specimens but one were found to have a decreased area of the outlet of the foramen magnum. In those 12 specimens, a decrease of 15%–35% was seen. Fusions of the atlas that were based primarily along the anterior rim of the foramen magnum resulted in more obstruction of its outlet. In general, the horizontal diameters of the outlet of these foramina were more decreased from the normal range.

Conclusions
These findings demonstrate that in the majority of cases, assimilation of the atlas to the occiput results in a compromised outlet of the foramen magnum.
A Cultural History of Crocodiles in the Philippines: Towards a New Peace Pact?
Authors: van der Ploeg Jan , van Weerd Merlijn , Persoon Gerard A. 
Published: April 2011

Abstract
Crocodiles have an image problem in the Philippines. In mainstream Filipino society crocodiles are considered dangerous man-eaters, and compared with corrupt government officials or selfish basketball players. It is often argued that these negative public attitudes towards crocodiles make in-situ crocodile conservation impossible in the Philippines. Only by securing economic benefits for rural communities through sustainable use can crocodiles be conserved. In this paper we contest this narrow utilitarian view. In fact indigenous peoples in the northern Sierra Madre have a history of co-existence with crocodiles. In the pre-Hispanic Philippines people feared and revered crocodiles: specific rules regulated the relationship between crocodiles and people. Traditional beliefs and practices enable people to share the landscape with a potentially dangerous carnivore. This forces us to rethink conventional conservation strategies that focus narrowly on economic values.

La localisation de la recherche-développement en France
Authors: Guieysse J.-A. 
Published: April 2011

La période 1960-1990 est favorable à la recherche-développement (R.-D.), dans l'industrie, en France.
D'après les localisations actuelles et la croissance de la R.-D. dans les régions, il est possible de distinguer plusieurs types régionaux contrastés, qui nuancent les idées générales sur l'organisation de l'espace français par les industries « à haute technologie ».
On examine particulièrement le cas de l'Ile-de-France. La R.-D. est le reflet des structures industrielles. Cependant, ces structures perdent de leur variété ; le rôle de métropole internationale joué par Paris renforce surtout le secteur tertiaire.
La montée en puissance du Hamas depuis la fin des années 1990
Authors: Napolitano Valentina 
Published: April 2011

Depuis la fin des années 90, le camp de réfugiés de Yarmouk a connu d’importantes recompositions politiques. Dans un contexte marqué par le détachement des réfugiés vis-à-vis des factions nationalistes et de gauche, le Hamas est parvenu à gagner un rôle politique et social croissant au sein du camp, notamment suite à l’établissement d’un bureau politique dans la capitale syrienne en 1993. Au cours de ce travail, je propose donc d’analyser le discours et les stratégies de mobilisation adoptées par le Hamas pour gagner le soutien des réfugiés. Cet article cherche à comprendre comment ce mouvement est parvenu à ajuster son action au contexte particulier du camp et du pays d’accueil, et comment il a bouleversé la vie sociale des réfugiés, leurs représentations et leurs modes de participation à la cause nationale.
Corpus littéraires : quelle place pour le nouveau ?
Authors: Ducos Dominique 
Published: April 2011

De manière récurrente, les professeurs examinateurs de l’oral de l’EAF évoquent avec regret le piètre renouvèlement des corpus littéraires présentés dans les descriptifs des candidats à cette épreuve. Une enquête portant sur un panel de trente descriptifs de l’EAF 2010 permet de pointer l’urgence d’une réflexion sur une problématique éludée depuis plusieurs années. Une analyse détaillée des lectures proposées permettra de vérifier la validité des plaintes des professeurs en charge des oraux de l’EAF, et donc la réalité d’une offre littéraire restreinte en classe de première. L’article analyse ensuite les arguments invoqués par les acteurs eux-mêmes pour justifier ce phénomène et met ainsi à jour les raisons et les canons implicites qui structurent les pratiques des enseignants de français en classe de première. Il envisage enfin des perspectives de renouveau des dits corpus qui s’appuient sur le paradoxe existant ainsi que sur la responsabilité de l’institution.
Poésies à l'école : pêche miraculeuse ?
Authors: Defrance Zorka 
Published: April 2011

Le pari de rendre la poésie accessible en tentant de la réduire à une forme et à des thématiques reconnaissables sclérose la représentation des élèves ou la confine tout au plus dans la représentation que se fait l’adulte d’une « poésie enfantine ». Peut-on faire le pari inverse en ouvrant le corpus à la diversité des textes et des auteurs aussi contemporains soient-ils pour que l’enfant y fasse le choix qui lui est réellement accessible ? La constitution d’une anthologie personnelle peut-elle engager la subjectivité du jeune lecteur et créer une correspondance entre l’intégrité du texte et l’intimité du lecteur ? À partir de quelles ressources bibliographiques créer le corpus ? Les manuels ? Les anthologies ? Les recueils ? Des exemples de création d’une anthologie personnelle au cycle 2 et 3 illustrent les tentatives d’une démarche.
Idéalisme et matérialisme. Hermann Cohen, sur Friedrich Albert Lange
Authors: Holzhey Helmut 
Published: April 2011

Résumé Confronté à l’orientation tendanciellement matérialiste des sciences de la nature dans le dernier tiers du xix e siècle, Hermann Cohen s’efforça d’offrir une fondation idéaliste de ces sciences en recourant à la philosophie transcendantale kantienne. Il fut en accord avec Friedrich Albert Lange dans le refus de toute métaphysique dogmatique, mais il ne partagea pas son naturalisme, et l’idéalisme poético-fictif qui le complétait. Alors que Lange, dans son Histoire du matérialisme , avait eu pour but de décrire l’autodissolution de la métaphysique matérialiste, Cohen voulut montrer comment le matérialisme débouchait dans un idéalisme méthodique, de provenance kantienne. En fin de compte, la distance dans le temps par rapport à Lange s’accroissant, il en vint à prêter un tel idéalisme à Lange lui-même ; ce qui est problématique.

Published: April 2011

Cementless hemiarthroplasty in hip fracture surgery has been associated with poorer outcomes and more pain than cemented hemiarthroplasty. The aim was to investigate clinical and radiographic outcomes for a cementless tapered titanium fully hydroyxapatite-coated (Corail® System) stem in this consecutive cohort of hip fracture patients. We retrospectively evaluated the results of 68 consecutive elderly patients with displaced intracapsular hip fractures, treated with this implant. Mean clinical follow-up was 4.3 years (2–6 years). One-year mortality was 24%. 95% of patients had no/occasional/mild mid-thigh pain, with moderate pain in 5%. 39% achieved independent or walking-stick mobility. 36 patients had follow-up radiography. Osseointegration was noted in 34, with a mixed bony/fibrous in-growth in 2. One patient had revision for subsidence of an undersized implant, with no conversions to total hip arthroplasty. The Corail® stem can be used effectively for the treatment of femoral neck fractures in the elderly.

Published: April 2011

AbstractThis Feature Article offers an overview of hybrid colloidal heterostructures of anisotropic semiconductor nanocrystals decorated with metals; primarily gold and platinum. The nonspherical shapes of the semiconductor components create a great variety of metal‐decorated hybrid nanostructures, whose synthesis and morphology are considered here. Due to the current interest in photocatalytic systems able to utilize solar energy for water‐splitting, the use of Pt‐decorated CdS‐based nanorods for hydrogen generation is specifically addressed. Great flexibility of the colloidal synthesis leading to well‐defined hybrid semiconductor–metal nanostructures drastically increases the possibility of their integration into functional nanosystems with novel synergetic properties, making them promising candidates for a variety of photovoltaic, catalytic, and sensing applications.
Well‐Ordered Large‐Pore Mesoporous Anatase TiO2 with Remarkably High Thermal Stability and Improved Crystallinity: Preparation, Characterization, and Photocatalytic Performance

Published: April 2011

AbstractThermally‐stable, ordered mesoporous anatase TiO2 with large pore size and high crystallinity has been successfully synthesized through an evaporation‐induced self‐assembly technique, combined with encircling ethylenediamine (EN) protectors to maintain the liquid crystal mesophase structure of TiO2 primary particles, followed by calcination at higher temperature. The structures of the prepared mesoporous TiO2 are characterized in detail by small‐angle and wide‐angle X‐ray diffraction, Raman spectra, N2 adsorption/desorption isotherms, and transmission electron microscopy. Experimental results indicate that the well‐ordered mesoporous structure could be maintained up to 700 °C (M700) and also possesses large pore size (10 nm), high specific BET surface area (122 m2 g−1), and high total pore volumes (0.20 cm3 g−1), which is attributed to encircling EN protectors for maintaining the mesoporous framework against collapsing, inhibiting undesirable grain growth and phase transformation during the calcination process. A possible formation mechanism for the highly stable large‐pore mesoporous anatase TiO2 is also proposed here, which could be further confirmed by TG/FT‐IR in site analysis and X‐ray photoelectron spectroscopy. The obtained mesoporous TiO2 of M700 exhibit better photocatalytic activity than that of Degussa P25 TiO2 for degradation of highly toxic 2,4‐dichlorophenol under UV irradiation. This enhancement is attributed to the well‐ordered large‐pore mesoporous structure, which facilitates mass transport, the large surface area offering more active sites, and high crystallinity that favors the separation of photogenerated electron‐hole pairs, confirmed by surface photovoltage spectra.
