OBJECT
Intrasylvian hematoma (ISH) is a subtype of intracranial hematoma caused by aneurysmal rupture and often presents with a poor initial neurological grade; it is not well studied. The aim of this study was to elucidate outcomes of aneurysmal subarachnoid hemorrhage (SAH) with ISH.

METHODS
Data for 97 patients with poor-grade SAH (World Federation of Neurosurgical Societies Grade IV or V) were retrospectively analyzed from a single-center, prospective, observational cohort database. Ultra-early surgical clipping, removal of hematoma, external decompression for brain swelling, and prevention of vasospasm by cisternal irrigation with milrinone were combined as an aggressive treatment. Characteristics and clinical courses of SAH with ISH were identified. The authors also evaluated any correlations between poor admission-grade SAH and ISH with good functional outcome.

RESULTS
Patients with poor admission-grade SAH and with ISH were more likely to have initial cerebral edema (p < 0.001, Mann-Whitney U-test), which significantly resolved overtime (p < 0.001, Mann-Whitney U-test). These patients had a better chance of functional survival (modified Rankin Scale scores of 1–3; OR 5.75; 95% CI 1.36–24.3; p = 0.017) at 6 months after hospital discharge, after adjustment for potential confounders such as younger age and better initial neurological grade by multivariable analysis.

CONCLUSIONS
ISH predicted good functional recovery from poor-grade aneurysmal SAH.
Carbon and Nitrogen Dynamics and Carbon Sequestration in Soils under Different Residue Management
Authors: Rahman M Mizanur 
Published: June 2015

A study was conducted at the research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during August 2011 to May 2012 in two consecutive rice seasons of T. aman and Boro using three types of organic residues viz. poultry manure, cowdung and rice straw as treatments to quantify their effects on soil carbon, nitrogen, carbon sequestration and CO2 emission. Poultry manure was found efficient to increase carbon and nitrogen contents in soils compared to rice straw and cowdung, which decreased with increased soil depths irrespective of residues. Rice straw released more CO2 compared to poultry manure and cowdung. However, a positive trend of carbon enrichment in soils was found with the application these residues. The carbon sequestration in soils under poultry manure was 1.46 t ha-1, while it was 1.26 and 1.19 t ha-1 in cowdung and rice straw, respectively. Application of poultry manure and cowdung in soils should be considered and recommended to increase carbon stock and fetch multiple benefits in agriculture. The Agriculturists 2014; 12(2) 48-55

Rice (Oryza sativa L.) is one of the major food crops in many countries. As the cultivation of rice requires huge volume of water, long term use of Arsenic contaminated groundwater for irrigation may result in the increase of arsenic concentration in the agricultural soil and eventually accumulation in rice grains. A micro level study was conducted to investigate the transfer of arsenic from irrigation water and soil to rice plants in the arsenic affected 8 unions of Chandina upazilla, Comilla district. The level of arsenic in irrigation water (0.12±0.08 and 0.67±0.07 mg l-1) was much above the WHO permissible limit of 0.01 mg l-1 for drinking water and FAO permissible limit of 0.10 mg l-1 for irrigation water. The total soil arsenic concentrations ranged from 3.21±0.80 to 8.74±2.83 mg kg-1 dry weight of soil, which was below the maximum acceptable limit for agricultural soil of 20.0 mg kg-1 as recommended by the European Community. The accumulation of arsenic in the grain ranged from 0.12±0.04 to 0.58±0.06 mg kg-1 in Boro and 0.16±0.04 to 1.06±0.20 mg kg-1 in T. Aman. Except grain sample (T. Aman) of one union, the grains in both Boro and T. Aman of all unions did not exceed 1.0 mg kg-1 dry weight of arsenic (the permissible limit of arsenic in rice according to WHO recommendation). Thus, till now rice has remained harmless for consumption in the study area. The results clearly showed that the arsenic content in the grains of Boro rice is correlated to the intensity of arsenic contamination of irrigation water and soil.

Published: June 2015

SummaryObjectives: To assess the influence of the use of Gelpi and Grevel retractors on multifidus muscle blood flow during hemilaminectomy, using a dorsolateral approach, for acute disc extrusion in dogs as measured by laser speckle contrast imaging (LSCI).Methods: Blood flow in the multifidus muscles was measured intra-operatively using LSCI prior to insertion of the retractors, immediately after hemilaminectomy and removal of the retractors, and after 10 minutes of lavage of the surgical site. Plasma creatine kinase levels were measured preoperatively and 12–24 hours postoperatively.Results: Muscular blood flow was significantly decreased following retraction and remained lower than initial values 10 minutes after lavage in all dogs. The decrease in blood flow was significantly greater with Gelpi re-tractors (n = 8) than with Grevel retractors (n = 10). No significant relation was found between the duration of retraction and postoperative changes in creatine kinase levels or blood flow.Clinical significance: Findings in this study demonstrate a drop in blood flow within the multifidus muscles using the dorsolateral approach regardless of retractor type used. Gelpi retractors seem to have greater influence on muscular blood flow than Grevel retractors. Further studies are warranted to confirm this second finding.
Floral cost vs. floral display: Insights from the megadiverse Myrtales suggest that energetically expensive floral parts are less phylogenetically constrained
Authors: Vasconcelos Thaís N. C. , Proença Carolyn E. B. 
Published: June 2015

• Premise of the study: Floral display describes the effect of flower size combined with the number of flowers per inflorescence. There is strong evidence that a floral‐display trade‐off operates under energetic constraint, with few‐flowered inflorescences likely to have larger flowers than many‐flowered inflorescences. Flower size can be estimated by different variables; thus, we propose that the variable for flower size that is most highly (negatively) correlated with the number of flowers per inflorescence will also be the best estimate of floral cost. Ranking the correlation with the phylogenetic signal of the variable can provide additional insight into the evolution of floral display.• Methods: The Myrtales were chosen as a model order based on age, worldwide distribution, and diversity of reproductive strategies. Ninety‐nine species representing all families and one quarter of generic diversity across its geographic and ecological range were sampled to reconstruct a phylogeny based on rbcL and ndhF sequences. Correlation coefficients were calculated for flower size variables vs. the number of flowers per inflorescence. Phylogenetic signal was measured for all variables and for floral display.• Key results: Flowers per inflorescence showed significant negative correlation with the following flower size variables (weakest to strongest): filament length < anther size < flower depth < flower diameter. As the correlation of each character with number of flowers per inflorescence rose (suggesting increased cost), the values for phylogenetic signal diminished (suggesting less constraint).• Conclusions: We conclude that energetically costly floral characters appear to be less phylogenetically constrained, while low‐cost floral characters maintain higher levels of phylogenetic inertia.
Do Residents Perform TKAs Using Computer Navigation as Accurately as Consultants?

Published: June 2015

The implantation of a total knee arthroplasty (TKA) is a milestone in a resident’s surgical training. Studies demonstrate higher loosening rates after TKA by inexperienced surgeons. Alignment outliers should be avoided to achieve a long implant survival. Therefore, our study questioned whether residents implant knee prostheses using computer navigation as accurately as experienced consultants.
The data for 662 consecutive TKAs were analyzed retrospectively. The operations were performed by 4 consultants (n=555) and 5 residents under supervision by a consultant (n=107). Cutting errors were recorded from the navigation data. The postoperative mechanical axis and operation time were recorded. Operation time was significantly prolonged if residents performed the operation vs consultants (139 vs 122 minutes, respectively). The analysis of cutting errors within each surgeon’s first 20 navigated operations resulted in no significant difference between residents and consultants. During the subsequent operations, a trend toward a more accurate placement of the prosthesis was detected for consultants. The rate of outliers with a mechanical axis deviation >2° was low and did not significantly differ between residents and consultants (3.7% vs 2.3%, respectively).
Our study shows that residents implant their first TKA using computer navigation as accurately as experienced consultants. However, the residents’ operations take longer and therefore incur additional costs for the teaching clinic.
Heterotopic Ossification Revisited
Authors: Mavrogenis Andreas F. , Soucacos Panayotis N. , Papagelopoulos Panayiotis J. 
Published: June 2015

Heterotopic ossification is the abnormal formation of mature lamellar bone within extraskeletal soft tissues where bone does not exist. Heterotopic ossification has been classified into posttraumatic, nontraumatic or neurogenic, and myositis ossificans progressiva or fibrodysplasia ossificans progressive. The pathophysiology is unknown. Anatomically, heterotopic ossification occurs outside the joint capsule without disrupting it. The new bone can be contiguous with the skeleton but generally does not involve the periosteum. Three-phase technetium-99m (99mTc) methylene diphosphonate bone scan is the most sensitive imaging modality for early detection and assessing the maturity of heterotopic ossification. Nonsurgical treatment with indomethacin and radiation therapy is appropriate for prophylaxis or early treatment of heterotopic ossification. Although bisphosphonates are effective prophylaxis if initiated shortly after the trauma, mineralization of the bone matrix resumes after drug discontinuation. During the acute inflammatory stage, the patient should rest the involved joint in a functional position; once acute inflammatory signs subside, passive range of motion exercises and continued mobilization are indicated.
Surgical indications for excision of heterotopic ossification include improvement of function, standing posture, sitting or ambulation, independent dressing, feeding and hygiene, and repeated pressure sores from underlying bone mass. The optimal timing of surgery has been suggested to be a delay of 12 to 18 months until radiographic evidence of heterotopic ossification maturation and maximal recovery after neurological injury. The ideal candidate for surgical treatment before 18 months should have no joint pain or swelling, a normal alkaline phosphatase level, and 3-phase bone scan indicating mature heterotopic ossification.

PURPOSE:
To evaluate the visual outcomes of myopic LASIK performed with the MEL 90 excimer laser (Carl Zeiss Meditec AG, Jena, Germany) using the Triple-A profile with a 500-Hz pulse rate.

METHODS:

Retrospective analysis of the first 286 myopic LASIK procedures (147 patients) by two experienced surgeons in which the VisuMax femtosecond laser and MEL 90 excimer laser (Carl Zeiss Meditec) were used following a standardized surgical technique. Inclusion criteria were preoperative spherical equivalent refraction (SEQ) up to −10.38 diopters (D), cylinder up to 5.00 D, and corrected distance visual acuity (CDVA) of 20/25 or better. No nomogram adjustments were made. Patients were observed for 3 months. Flap thickness was between 80 and 110
µ
m and optical zone was between 6 and 7 mm. Standard outcomes analysis was performed.

RESULTS:

Preoperatively, mean SEQ was −3.83 ± 1.83 D (range: −0.13 to −10.38 D) and mean cylinder was −0.94 ± 0.86 D (range: 0.00 to −5.00 D). Mean age was 36.4 years (range: 18.2 to 74.1 years) with 50% female patients. Of this population, 138 eyes were treated by one surgeon and 148 eyes by another. The mean predictability of SEQ was −0.13 ± 0.34 D (range: −1.00 to +1.00 D). Postoperative SEQ was ±0.50 D in 88% and ±1.00 D in 100% of eyes. Preoperative CDVA was 20/20 or better in 97% of eyes. Postoperative uncorrected distance visual acuity was 20/20 or better in 92% and 20/25 or better in 99% of eyes. One line of CDVA was lost in 6% of eyes and no eyes lost two or more lines. There was statistically significant improvement in mesopic contrast sensitivity (CSV-1000) at 3 (
P
= .021), 6, 12, and 18 (all
P
≤.001) cycles per degree.

CONCLUSIONS:
The MEL 90 excimer laser using the Triple-A ablation profile with a 500-Hz pulse rate was found to achieve a small but real increase in contrast sensitivity and high efficacy for myopia up to −10.00 D and cylinder up to 5.00 D without the need for a nomogram adjustment.

Les textes réglementaires incitant à tenir compte de la sensibilité du milieu local foisonnent au niveau français et européen. Cependant, ces textes ne proposent pas de cadre méthodologique pour l'évaluation de la sensibilité du milieu. Parallèlement à cela, les outils d'évaluation des impacts environnementaux des entreprises se formalisent et se multiplient,mais comment évaluer l'impact d'une activité et caractériser la sensibilité de son contexte local ? Cet article propose de combler ce manque, en apportant une méthode d'évaluation de la sensibilité du milieu récepteur. Cette méthode est basée sur la définition, l'identification et l'organisation des thèmes caractérisant cette sensibilité (thèmes statiques : eaux souterraines, eaux superficielles, sol superficiel et air ; thèmes dynamiques : caractéristiques des milieux biologiques et humains). L'approche proposée est une approche qualitative basée sur un questionnaire simple et rapide. La sensibilité est évaluée selon une échelle à quatre niveaux allant de peu sensible à très sensible. L'objectif final est l'intégration de la sensibilité du milieu dans une méthodologie globale d'évaluation des performances environnementales de techniques en vue de les comparer puis de les valider « meilleures techniques disponibles ». L'article présente un exemple d'application de cette méthode.

In Morroco little olive mills called “maâra” release a great quantity of olive cake in environment after extracting olive oil because there is no regulation. The chemical composition of olive cake and the important quantity released lead to environmental pollution, not acceptable with respect to the principle of sustainable development. To remedy the problem we propose a valorisation flowsheet including production of glycerin as made in other countries, and production of furfural which Morocco imports to produce lubrication oil.
Au Maroc, les petites huileries artisanales appelées maâsras, après avoir extrait l'huile des olives, rejettent de grande quantité de déchets solides ou grignons dans le milieu environnemental parce qu'il n'y a pas de réglementation. La composition chimique des grignons et le fort tonnage rejeté constituent une pollution pour des régions fragiles, incompatible avec le principe du développement durable. Pour y remédier nous proposons un schéma de valorisation des grignons avec la production de glycérine qui est déjà appliquée dans d'autres pays et la production de furfural qui sert à la fabrication des huiles lubrifiantes que le Maroc importe.

Published: June 2015

Soil PAHs contamination is now becoming of great concern. This pollution has a negative impact on activities directly or indirectly related to the soil, but it has also potential consequences for human health and the quality of the ecosystem. Indeed, polycyclic aromatic hydrocarbons (PAHs) represent an important class of environmental pollutants, of which some are known to be mutagenic and carcinogenic. Consequently, the US Environmental Protection Agency (EPA) has listed some PAHs among the priority pollutants to be monitored in aquatic and terrestrial ecosystems. Bioremediation, the use of organisms for the treatment of soil pollution, have received considerable interest in recent years because of its ecological aspect and because of potential cost savings compared to conventional non biological techniques. The objective of this paper is to review findings concerning the potential of the organisms used for bioremediation of soils polluted with PAHs. At present, numerous organisms (bacteria, fungi, algae and plants) are reported to metabolise PAHs. The several enzymatic mechanisms known to be involved in the PAHs degradation by the different biological systems will be underlined.
Parmi les techniques de dépollution et de réhabilitation des sols (physiques, chimiques et biologiques), la bioremédiation (détoxification ou minéralisation d'un polluant par les organismes vivants) des sols in situ semble être une méthode d'intérêt d'un point de vue économique et écologique. Contrairement aux autres procédés (incinération, lessivage du sol…) où les polluants sont souvent transférés et non détruits, la biodégradation peut permettre la minéralisation du xénobiotique, et donc sa disparition. De plus, cette technique est particulièrement adaptée pour le traitement des hydrocarbures polycycliques aromatiques (HPAs), contaminants comptant parmi les plus récalcitrants et les plus toxiques (pouvoirs cancérigène et mutagène). Il a été démontré que de nombreux organismes, procaryotes ou eucaryotes (algues, bactéries, champignons, plantes), possèdent la capacité à dégrader les HPAs. La présente revue a pour but de faire le point sur l'état actuel des connaissances concernant les organismes utilisés en tant qu'agents biologiques efficaces de dépollution des sols contaminés par les HPAs. Les systèmes enzymatiques impliqués dans la dégradation des HPAs chez ces différents systèmes biologiques seront décrits.

The demolished materials recycling responds to concerns conserve or to economize natural aggregates for the requirements to functioning of building sites. The project aim is also to protect environment by reducing uncontrolled dump sites of rubble. Nevertheless, the use of this kind of aggregates may cause problems, due to their high porosity which resulting an absorption of mixing water (difficulty to control of concrete fresh proper ties) and consequently a decrease the strength and durability of concrete.This experimental work is conducted in order to recover aggregates resulting from demolished concretes. Tests of physical and mechanical characterization of recycled aggregates (sand and gravel), were performed in order to set up compliance to the standardization. Concretes of different granular combinations (natural/recycled) with and without addition of superplasticizer are composed, as well as application of various ratios (gravel/sand).Also, the proper ties of these kinds of concretes were tested in fresh and hardened forms. The application of the recycled aggregates resulted in an evidence that they can be providing a concrete with resisting characteristic of 28 days quite higher than 20 MPa. The combinations of natural/recycled aggregates can be considered for certain applications without major risk.
Le recyclage des matériaux de démolition répond aux soucis de préserver ou d’économiser les granulats naturels pour les besoins de fonctionnement des chantiers. Cette entreprise va aussi dans le sens de la promotion du respect de l’environnement par l’élimination des décharges sauvages de gravats. Cependant, leur utilisation en tant que granulats pour le béton pose problème du fait de leur forte porosité qui se traduit par une absorption d’eau de gâchage (contrôle des propriétés du béton frais délicate) et par voie de conséquence diminution de la résistance et la pérennité du béton.L’intérêt de ce travail expérimental est de valoriser les granulats issus des bétons de démolition. Des tests de caractérisations physiques et mécaniques sur les granulats recyclés (sable et gravier) comme granulats de substitution ont été effectués pour la mise en conformité avec la norme. Des compositions de bétons ont été testées avec différentes compositions (naturels/recyclés) différents rapports gravier/sable avec ou sans fluidifiant. Les propriétés des bétons frais et durcis sont déterminées. Les granulats recyclés peuvent fournir un béton de résistance caractéristique à 28 jours nettement supérieure à 20 MPa. Le choix de béton incluant des combinaisons en granulats (naturels/recyclés) est proposé pour certaines applications.
