Cette étude vise la sélection d’arbres« plus » sur la base des caractères den- drométriques et des propriétés du bois dans des plantations de teck au Bénin et au Togo. La croissance de 569 arbres dans 5 forêts au Togo et 90 arbres dans 3 forêts au Bénin a été évaluée en mesu- rant le diamètre à hauteur de poitrine, la hauteur totale et la hauteur du fût. Les propriétés suivantes du bois ont été éva- luées et prises en compte pour la sélec- tion finale d’arbres « plus » : densité, pourcentage de bois de cœur et couleur. La durabilité naturelle du bois de cœur, le point de saturation des fibres, le module d’élasticité et les retraits ont été évalués sur la base de modèles spectroscopiques dans le proche infrarouge, préalablement construits. Nos résultats montrent qu’au Togo la variabilité inter-arbres en forêt est assez forte pour l’accroissement annuel en hauteur (0,81 ± 0,27 m), en circonfé- rence (2,95 ± 1,02 cm) et en hauteur des fûts (10,64 ± 3,51m). Au Bénin, si les per- formances dendrométriques des arbres ne varient pas de façon significative entre les forêts, pour la hauteur des fûts (10,99 ± 3,80 m), les valeurs du coeffi- cient de variation sont plus élevées (40 %) pour la forêt de Koto. Prenant en compte les propriétés du bois, la sélection finale multicritères montre que les peuplements d’Avétonou et de Tchorogo au Togo consti- tuent un groupe homogène affichant les plus fortes valeurs pour la densité du bois et le pourcentage de bois de cœur. Les arbres des forêts de Haho-Baloe et Eto ont des valeurs plus faibles pour la dura- bilité naturelle, le module d’élasticité, le pourcentage de bois de cœur et la densité du bois. Au Bénin, les arbres de la forêt d’Agrimey ont une densité plus élevée mais les valeurs pour le point de satu- ration des fibres, la durabilité naturelle et le retrait du bois sont similaires pour les trois forêts. La variabilité des perfor- mances dendrométriques et de la qualité du bois des arbres-candidat nous ont per- mis de sélectionner 33 arbres « plus ».

L’objectif de cette étude est d’évaluer au Bénin l’efficacité du réseau des aires protégées dans la conservation des habi- tats favorables et prioritaires de certaines espèces ligneuses d’importance socio-éco- nomique. Il s’agit de Afzelia africana, Anogeissus leiocarpa, Burkea africana, Daniellia oliveri, Detarium microcarpum, Prosopis africana et Khaya senegalensis. Les techniques basées sur le principe d’en- tropie maximale (Maxent) combinées avec les SIG ont été utilisées pour projeter les habitats favorables de ces sept espèces ; le logiciel Zonation a été utilisé pour la modé- lisation des habitats prioritaires. Les points de présence des espèces ont été collectés et associés aux variables bioclimatiques dérivées de la température mensuelle et de la pluviométrie obtenues à partir de la base de données en ligne de AfriClim, ainsi qu’à la variable édaphique (sol). En terme de déterminisme environnemental, les variables bioclimatiques telles que l’écart diurne moyen de la température (Bio2), les précipitations annuelles moyennes (Bio12), l’évapotranspiration potentielle (ETP) et la variable biophysique sol, sont prédictives pour les distributions des sept espèces. Les habitats protégés plus favo- rables aux sept essences dans la zone gui- néenne commencent aux limites de la forêt classée de Kétou (7°43’N), dans la zone soudano-guinéenne, à partir de la lati- tude de la forêt classée d’Agoua (8°30’N), et dans la zone soudanienne à partir de la latitude de la Pendjari (10°35’N). Pour la conservation des habitats prioritaires, l’étude de représentation révèle que, dans les zones soudaniennes (9°75’-12°27’N), guinéenne (6°50’-7°40’N) et soudano-gui- néenne, les aires protégées sont respec- tivement efficaces, peu efficaces et non efficaces.

En Amérique tropicale, la régénération de l’acajou à grandes feuilles, Swietenia macrophylla King, essence commerciale majeure, est problématique en raison de ses caractéristiques de fructification et de dispersion et de sa faible tolérance à l’ombre et sa réaction à l’exploitation forestière. Dans l’État de Quintana Roo, au Mexique, les brûlis abandonnés offrent d’excellents espaces pour l’établissement de jeunes plants, mais un moyen effi- cace permettant d’assurer la survie des semences reste à identifier. La présente étude s’est attachée à évaluer la pro- babilité de prédation des semis directs d’acajou, en analysant les effets de trois types de traitement (quatre types de pro- tection des semences, deux méthodes de semis et deux moments de semis dans la journée). Le pourcentage moyen de semences éliminées ou consommées en partie sur une période de 12 heures varie de 1,1 à 7,7 % selon les quatre types de traitement des semences mais ne varie pas selon les deux méthodes de semis. La précipitation au moment du semis est fortement positive pour la reprise des semences, tandis que la température journalière minimale a un effet légère- ment négatif. L’effet de la date des semis, selon le calendrier julien, est positif pour la survie des semences. La prédation des semences ne varie pas selon les traite- ments de protection qui permettent l’ac- cès aux seuls rongeurs, aux seuls insectes et aux deux, et la prédation est plus importante avec ces trois types de trai- tement qu’avec le traitement interdisant totalement l’accès aux prédateurs. La pré- dation des semences n’est pas influencée par le moment du semis dans la journée. Le semis direct est favorable à la régéné- ration de l’acajou, notamment lorsque les semences sont trempées pendant au moins deux semaines avant le semis pour réduire les risques de prédation et aug- menter les chances de survie et de reprise.

Cette étude s’est déroulée dans une plan- tation forestière en Amérique centrale, proche de la ville de Diriamba au Nica- ragua, où des plantations de teck sur 48,9 ha, dans une zone de reboisement de 76,5 ha, sont renouvelées depuis 2006 (2006 : 7,90 ha ; 2007 : 13,63 ha ;2008 : 11,93 ha ; 2009 : 12,87 ha ; 2010 :21,70 ha). Cette plantation sort de l’ordi- naire du fait de l’espacement de 1 x 1 m des arbres et des facteurs écologiques limitants de cette zone tropicale aride. L’espacement de 1 x 1 m a été choisi pour favoriser la croissance en hauteur et obtenir ainsi des tiges de haute taille, et pour limiter les ramifications afin d’éviter la formation de houppiers importants. Cela permet de démarrer une production de poteaux de teck, adaptés à certaines constructions, dès la première coupe d’éclaircissement. Les paramètres de croissance des tecks (hauteur, circonfé- rence) ont été mesurés dans les placettes expérimentales mises en place en 2011. Des données complémentaires (morta- lité, arbres cassés ou tordus) ont égale- ment été relevées. Une méthodologie de terrain a été développée et les résultats restitués sous forme de tableaux et gra- phiques. Une évaluation statistique des paramètres de croissance a été menée à partir des mesures prises sur les placettes expérimentales délimitées dans la planta- tion. Les jeunes arbres plantés la même année ont été comparés selon leur prove- nance en termes de hauteur, de circonfé- rence, de productivité et de mortalité. Au total, 10 955 arbres sur 143 placettes ont été mesurés. Sur ces peuplements de 1 à 5 ans d’âge, le bois sur pied total est estimé à 1 287,89 m3, la masse moyenne de bois à l’hectare à 17,89 m3, la hauteur moyenne des peuplements à 3,03 m et la circonférence moyenne à hauteur de poitrine à 2,74 cm. Les arbres cassés représentent 5,64 %, les arbres tordus 5,66 % et la mortalité moyenne s’établit à 21,48 %.

Published: December 2017

Background:
There are conflicting data on the results of irrigation and debridement with component retention in patients with acute periprosthetic hip infections. The goals of this study were to examine contemporary results of irrigation and debridement with component retention for acute infection after primary hip arthroplasty and to identify host, organism, antibiotic, or implant factors that predict success or failure.

Methods:
Ninety hips (57 total hip arthroplasties and 33 hemiarthroplasties) were diagnosed with acute periprosthetic hip infection (using strict criteria) and were treated with irrigation and debridement and component retention between 2000 and 2012. The mean follow-up was 6 years. Patients were stratified on the basis of McPherson criteria. Hips were managed with irrigation and debridement and retention of well-fixed implants with modular head and liner exchange (70%) or irrigation and debridement alone (30%). Seventy-seven percent of patients were treated with chronic antibiotic suppression. Failure was defined as failure to eradicate infection, characterized by a wound fistula, drainage, intolerable pain, or infection recurrence caused by the same organism strain; subsequent removal of any component for infection; unplanned second wound debridement for ongoing deep infection; and/or occurrence of periprosthetic joint infection-related mortality.

Results:
Treatment failure occurred in 17% (15 of 90 hips), with component removal secondary to recurrent infection in 10% (9 of 90 hips). Treatment failure occurred in 15% (10 of 66 hips) after early postoperative infection and 21% (5 of 24 hips) after acute hematogenous infection (p = 0.7). Patients with McPherson host grade A had a treatment failure rate of 8%, compared with 16% (p = 0.04) in host grade B and 44% in host grade C (p = 0.006). Most treatment failures (12 of 15 failures) occurred within the initial 6 weeks of treatment; failures subsequent to 6 weeks occurred in 3% of those treated with chronic antibiotic suppression compared with 11% of those who were not treated with suppression (hazard ratio, 4.0; p = 0.3).

Conclusions:
The success rate was higher in this contemporary series than in many previous series. Systemic host grade A was predictive of treatment success.

Published: December 2017

Background:
As concerns regarding health-care expenditure in the U.S. remain at the national forefront, outpatient arthroplasty is an appealing option for carefully selected patient populations. The purpose of this study was to determine the nationwide trends and complication rates associated with outpatient total knee arthroplasty (TKA) in comparison with standard inpatient TKA.

Methods:
We performed a retrospective review of the Humana subset of the PearlDiver Patient Record Database to identify patients who had undergone TKA (Current Procedural Terminology [CPT] code 27447) as either outpatients or inpatients from 2007 to 2015. The incidence of perioperative medical and surgical complications was determined by querying for relevant International Classification of Diseases, Ninth Revision (ICD-9) and CPT codes. Multivariate logistic regression analysis adjusted for age, sex, and Charlson Comorbidity Index (CCI) was used to calculate odds ratios (ORs) of complications among outpatients relative to inpatients treated with TKA.

Results:
Cohorts of 4,391 patients who underwent outpatient TKA and 128,951 patients who underwent inpatient TKA were identified. The median age was in the 70 to 74-year age group in both cohorts. The incidence of outpatient TKA increased across the study period (R2 = 0.60, p = 0.015). After adjustment for age, sex, and CCI, outpatient TKAs were found to more likely be followed by tibial and/or femoral component revision due to a noninfectious cause (OR = 1.22, 95% confidence interval [CI] = 1.01 to 1.47; p = 0.039), explantation of the prosthesis (OR = 1.35, CI = 1.07 to 1.72; p = 0.013), irrigation and debridement (OR = 1.50, CI = 1.28 to 1.77; p < 0.001), and stiffness requiring manipulation under anesthesia (OR = 1.28, CI = 1.17 to 1.40; p < 0.001) within 1 year. Outpatient TKA was also more frequently associated with postoperative deep vein thrombosis (OR = 1.42, CI = 1.25 to 1.63; p < 0.001) and acute renal failure (OR = 1.13, CI = 1.01 to 1.25; p = 0.026).

Conclusions:
With the potential to minimize arthroplasty costs among healthy patients, outpatient TKA is an increasingly popular option. Nationwide data from a private insurance database demonstrated a higher risk of perioperative surgical and medical complications including component failure, surgical site infection, knee stiffness, and deep vein thrombosis.

Authors: Mendez Gregory M. , Patel Yash M. , Ricketti Daniel A. , Gaughan John P. , Lackman Richard D. , Kim Tae Won B. 
Published: December 2017

Background:
Patients who undergo orthopaedic oncologic surgical procedures are at increased risk of developing a venous thromboembolism (VTE). Guidelines from surgical societies are shifting to include aspirin as a postoperative VTE prophylactic agent. The purpose of this study was to review our experience using aspirin as postoperative VTE prophylaxis for orthopaedic oncologic surgical procedures.

Methods:
This study was a retrospective review of patients diagnosed with a primary malignant soft-tissue or bone tumor or metastatic carcinoma. Demographic information, histopathologic diagnosis, VTE history, surgical procedure, and VTE prophylaxis were analyzed. VTE rates in the overall and prophylactic-specific cohorts were recorded and compared.

Results:
A total of 142 distinct surgical procedures in 130 patients were included. VTE prophylaxis with aspirin was used after 103 procedures, and non-aspirin prophylaxis was used after 39. In 33 cases, imaging was used to investigate for VTE because of clinical signs and symptoms. VTE developed after 7 (4.9%) of the 142 procedures. There were 6 deep venous thromboses (DVTs) and 1 pulmonary embolism, and 2 of the VTEs presented in patients with a VTE history. VTE developed in 2.9% (3) of the 103 aspirin cases and 10.3% (4) of the 39 non-aspirin cases. No patient in the aspirin group who had been diagnosed with metastatic carcinoma, malignant soft-tissue sarcoma, lymphoma, or multiple myeloma developed a VTE. Risk factors for VTE development included diabetes mellitus (odds ratio [OR] = 10.40, 95% confidence interval [CI] = 1.61 to 67.30), a history of VTE (OR = 7.26, 95% CI = 1.19 to 44.25), postoperative transfusion (OR = 34.50, 95% CI = 3.94 to 302.01), and estimated blood losses of 250 mL (OR = 1.50, 95% CI = 1.11 to 2.03), 500 mL (OR = 2.26, 95% CI = 1.23 to 4.13), and 1,000 mL (OR = 5.10, 95% CI = 1.52 to 17.04).

Conclusions:
Aspirin may be a suitable and effective option for VTE chemoprophylaxis in patients treated with orthopaedic oncologic surgery, especially those diagnosed with a soft-tissue sarcoma. Research with a more advanced study design is required.

Simulation-Based Educational Module Improves Intern and Medical Student Performance of Closed Reduction and Percutaneous Pinning of Pediatric Supracondylar Humeral Fractures
Authors: Butler Bennet A. , Lawton Cort D. , Burgess Jamie , Balderama Earvin S. , Barsness Katherine A. , Sarwark John F. 
Published: December 2017

Background:
Simulation-based education has been integrated into many orthopaedic residency programs to augment traditional teaching models. Here we describe the development and implementation of a combined didactic and simulation-based course for teaching medical students and interns how to properly perform a closed reduction and percutaneous pinning of a pediatric supracondylar humeral fracture.

Methods:
Subjects included in the study were either orthopaedic surgery interns or subinterns at our institution. Subjects all completed a combined didactic and simulation-based course on pediatric supracondylar humeral fractures. The first part of this course was an electronic (e)-learning module that the subjects could complete at home in approximately 40 minutes. The second part of the course was a 20-minute simulation-based skills learning session completed in the simulation center. Subject knowledge of closed reduction and percutaneous pinning of supracondylar humeral fractures was tested using a 30-question, multiple-choice, written test. Surgical skills were tested in the operating room or in a simulated operating room. Subject pre-intervention and post-intervention scores were compared to determine if and how much they had improved.

Results:
A total of 21 subjects were tested. These subjects significantly improved their scores on both the written, multiple-choice test and skills test after completing the combined didactic and simulation module. Prior to the module, intern and subintern multiple-choice test scores were significantly worse than postgraduate year (PGY)-2 to PGY-5 resident scores (p < 0.01); after completion of the module, there was no significant difference in the multiple-choice test scores. After completing the module, there was no significant difference in skills test scores between interns and PGY-2 to PGY-5 residents. Both tests were validated using the scores obtained from PGY-2 to PGY-5 residents.

Conclusions:
Our combined didactic and simulation course significantly improved intern and subintern understanding of supracondylar humeral fractures and their ability to perform a closed reduction and percutaneous pinning of these fractures.

Abstract
Safe disposal of children's feces is as essential as the safe disposal of adults' feces. However, there is widespread belief that feces of infants and young children are not harmful. This study aimed to assess child feces disposal practice and associated factors in northern Ethiopia. A community-based cross-sectional study design was employed among 445 mothers with children less than five years of age. Results are presented in tables, graphs, and texts. Mothers within the age category of 25–34 were 3.7 times more likely to practice safe child feces disposal than mothers in the age range of 15–24 [AOR (95% C.I.) = 3.73 (1.06, 13.10)]. Government employed mothers were 99.92% less likely to practice safe child feces disposal compared to housewives. Urban dwellers were 3.5 times more likely to practice safe child feces disposal than rural areas [AOR (95% C.I.) = 3.51 (1.24, 9.99)]. In general, child feces disposal practice was low in the study area. Higher age category of mothers, housewives, and urban dwellers were factors associated with safe child feces disposal practices. Therefore, further intervention should be designed to improve safe child feces disposal among lower age category, employees, rural residents, and those defecating on floors.

Abstract
Many emerging contaminants pass through conventional wastewater treatment plants, contaminating surface and drinking water. The implementation of advanced oxidation processes in existing plants for emerging contaminant remediation is one of the challenges for the enhancement of water quality in the industrialised countries. This paper reports on the production of a TiO2 nano-layer on quartz wool in a relevant amount, its characterisation by X-ray diffraction and scanning electron microscopy, and its use as a photocatalyst under ultraviolet radiation for the simultaneous mineralisation of five emerging organic contaminants (benzophenone-3, benzophenone-4, carbamazepine, diclofenac, and triton X-100) dissolved in deionised water and tap water. This treatment was compared with direct ultraviolet photolysis and with photocatalytic degradation on commercial TiO2 micropearls. The disappearance of every pollutant was measured by high performance liquid chromatography and mineralisation was assessed by the determination of total organic carbon. After 4 hours of treatment with the TiO2 nano-coated quartz wool, the mineralisation exceeds 90% in deionised water and is about 70% in tap water. This catalyst was reused for seven cycles without significant efficiency loss.

Published: December 2017

Abstract
The start-up phase of a membrane bioreactor (MBR) for municipal wastewater treatment was studied to determine the effect of temperature on the organic matter removal and heterotrophic kinetics. The MBR system was analyzed during four start-up phases with values of hydraulic retention time (HRT) of 6 h and 10 h, mixed liquor suspended solids (MLSS) concentrations of 4,000 mg L−1 and 7,000 mg L−1 in the steady state, and temperature values of 11.5, 14.2, 22.9 and 30.1 °C. The influence of temperature on the biological process of organic matter removal was determined through the Arrhenius equation and Monod model. At the most favorable operation conditions of HRT (10 h) and MLSS (7,000 mg L−1) corresponding to phase 4, the effect of these variables dominated over the temperature. Heterotrophic biomass from phase 2 (HRT = 10 h, MLSS = 4,000 mg L−1 and T = 30.1 °C) had the highest values of chemical oxygen demand (COD) degradation rate (rsu,H), implying less time to remove organic matter and shorter duration of the start-up phase.
