Three-port versus four-port laparoscopic cholecystectomy in acute and chronic cholecystitis
Dhafir Al-Azawi, Nariman Houssein, Abu Rayis, Donal McMahon, Dermot J Hehir
BMC Surgery , 2007, DOI: 10.1186/1471-2482-7-8
Abstract: The medical records of 495 patients who underwent LC between September 1999 and September 2003 were reviewed. Variables such as complications, operating time, conversion to open procedure, hospital stay, and analgesia requirements were compared.Two hundred and eighty-three patients underwent three-port LC and 212 patients underwent four-port LC. In total, 163 (32.9%) patients were diagnosed with AC and 332 (67.1%) with CC by histology. There was no statistical difference between the three and four-port groups in terms of complications, conversion to open procedure (p = 0.6), and operating time (p = 0.4). Patients who underwent three-port LC required less opiate analgesia (pethidine) than those who underwent four-port LC (p = 0.0001). The hospital stay was found to be related to the amount of opiates consumed (p = 0.0001) and was significantly shorter in the three-port LC group (p = 0.005).Three-port LC is a safe procedure for AC and CC in expert hands. The procedure offers considerable advantages over the traditional four-port technique in the reduction of analgesia requirements and length of hospital stay.Since its foundation in 1987 by Philip Mouret of Lyon, laparoscopic cholecystectomy (LC) has been the procedure of choice for symptomatic gall bladder disease [1]. Since then, there have been many changes and improvements in the technique. Traditional LC is performed using four-port technique [2,3]. Reducing the size or number of ports did not affect the safety of the procedure and further enhanced the advantages of laparoscopic over open cholecystectomy [4]. These modifications actually reduced the pain and analgesia requirement [5]. Three trocars and even two trocars were used to perform LC [4,6], as has using mini-instruments, authors of these new techniques claimed that these techniques took a similar time to perform and caused less postoperative pain than the standard laparoscopic cholecystectomy [5,7]. Some authors even advised for procedures as needlescope
A Brief Follow-Up Report on 228 Medial Rotation Total Knee Replacements at a Mean of 8.5 Years (0 - 19)  [PDF]

International Journal of Clinical Medicine (IJCM) , 2015, DOI: 10.4236/ijcm.2015.612121
Abstract: We present an update in our earlier report on the Medial Rotation Total Knee Arthroplasty (TKA) when a cohort of 228 TKAs in 189 patients (78 M; 111 F) with a mean age of 67.9 years (28 - 90) was reported at a mean follow-up of six years (1 - 13). At that time, the ten-year survivorship for revision for any reason was 94.5% (95% confidence interval (CI): 85.1 - 100), but only 21 knees were at risk at that tenth year. The 10th annual report of the National Joint Registry (NJR) of England, Wales and Northern Ireland reported a deterioration in survivorship of the Medial Rotation TKA beyond the seventh year of follow-up. This implant previously had enjoyed the lowest rate of revision for any reported brand of prosthesis. As a result, we undertook a comprehensive audit of our original cohort at a mean follow-up of 8.5 years (0 - 19). With revision for aseptic loosening, and revision for any reason as the endpoints, with 125 prostheses at risk at ten years, the ten-year survivorship was 96.7% (95% CI: 93.3 - 100) and 92.3% (95% CI: 87.7 - 93.7) respectively. We have confirmed a decline in survivorship at ten years compared to our initial report. We believe that our results probably provide a more accurate picture of the longevity of the implant than figures available from the NJR, as they are based on detailed contemporary enquiries into each patient’s circumstances. Only ten knees in seven patients were lost to follow-up in our review.

Community Tenure Rights and REDD+: A Review of the Oddar Meanchey Community Forestry REDD+ Project in Cambodia
Donal Yeang
ASEAS : ?sterreichische Zeitschrift für Südostasienwissenschaften , 2012,
Abstract: Tenure rights over land, forest, and carbon have become a contentious issue within REDD+ implementation across the tropics because local communities could be excluded from REDD+ benefits if land tenure or use and access rights are not clear. This study aims to understand and assess tenure arrangements under the first REDD+ demonstration project in Cambodia, the Oddar Meanchey Com- munity Forestry REDD+ Project. In particular, the study explores the following questions: (1) How are tenure rights arranged in the Oddar Meanchey REDD+ Project? (2) Does the tenure regime recognise the rights of local communities to their land and its associated resources? (3) What kind of institu- tions are put in place to support tenure rights of local communities in the project? The author conducted in-depth semi-structured interviews with key stakeholders and complemented the analysis by participant observation and a review of policy documents and secondary literature. The major finding of this study is that the local communities in the project are still given rights to use and access forest resources, although carbon rights belong to the government. While the government retains ownership over carbon credits, it agreed that at least 50 percent of the net revenue from the sale of carbon credits will flow to participating communities. ------ Besitzrechte an Land, Wald und CO2 sind zu einer umk mpften Angelegenheit in der REDD+ Implementierung in den Tropen geworden. Diese Studie versucht die Besitzregelungen im ersten REDD+ Demons- trationsprojekt in Kambodscha, dem Oddar Meanchey Community Forestry REDD+ Project, zu verstehen und zu bewerten. Die Untersuchung analysiert dabei insbesondere folgende Fragen: (1) Wie sind Besitzrechte im Oddar Meanchey REDD+ Projekt geregelt? (2) Erkennt das Besitzsystem die Rechte von lokalen Gemeinschaften an ihrem Land und den dazugeh rigen Ressourcen an? (3) Welche Institutionen werden geschaffen, um die Besitzrechte von lokalen Gemeinschaften im Projekt zu st rken? Dazu führte der Autor semi-strukturierte Interviews mit zentralen InteressensvertreterInnen, wandte teilnehmende Beobachtung an und nahm eine Analyse von politischen Rahmenbedingungen und Sekund rliteratur vor. Das Hauptergebnis der Studie ist, dass lokale Gemeinschaften im Projekt nach wie vor Nutzungs- und Zugangsrechte zu Waldressourcen haben, w hrend die Regierung über die CO2-Rechte verfügt. Auch wenn die Regierung Eigentümerin der CO2-Zertifikate bleibt, wurde vereinbart, dass 50 Prozent der Nettoeinnahmen aus dem Verkauf der Zertifikate an die teilnehmenden Gemeinschafte

International Patent Protection: Time for a fully EU Functioning Supra-National Patent Mechanism
Donal Loftus
Journal of International Commercial Law and Technology , 2011,
Abstract: Larger industrial companies have become increasingly global in their functions and aspirations. With regard to patents, it is increasingly common for a multinational company to face alleged infringing acts committed by the same competitor in several countries. Securing international patent protection both at the acquisition and the enforcement stage is the corollary to the cross border exploitation of patents. The regulation of transnational trade and the international exploitation of patent rights have brought about international agreements concerning these closely related issues, such as international patent granting power, international harmonization of patent laws and uniform systems of jurisdiction and choice of law rules applicable to patent enforcement as well as other areas. However, there is an increasingly strained relationship between international patent acquisition and enforcement which is the dominant focus of this paper. Whilst a network of international agreements facilitates the grant of increasingly similar patent rights in many countries, cross border patent enforcement through the application of the relevant private international rules has been very weak. From a private international law perspective, the legal independence and territorial limitations of patent rights has severe implications for the application of the relevant jurisdictional and choice of law rules.Therefore, cross-border adjudication has indeed been challenged in the patent area. This paper seeks to focus on the problems associated with acquiring and enforcing patent rights at a multi-jurisdictional level, particularly within the EU.
Managing Soil Erosion in Northern Ireland: A Review of Past and Present Approaches
Donal Mullan
Agriculture , 2013, DOI: 10.3390/agriculture3040684
Abstract: In recent decades, the off-site transport of sediment and nutrients from agricultural land into the neighbouring natural and built environment has become a more pressing environmental sustainability issue than the on-site threats of soil erosion in many of the world’s temperate regions. In the temperate region of Northern Ireland, recent studies have highlighted the off-site issue of soil erosion by water in the present day, and projected that the problem may become more widespread and serious in a changing climate. This review paper examines how this problem is being managed in the present day, and draws on examples of policy in other countries to consider how the role of policy needs to be modified for more effective management. Farmers are generally not adhering to present-day policy and “keeping their land in good agricultural and environmental condition”. A range of suggested changes in policy and practice is offered, ranging from educating farmers on erosion mitigation and remediation to developing specific policies aimed at targeting soil erosion and conservation as their sole objective. An increase in the evidence base from measured erosion rates in the field is postulated to be the most likely route to achieving policy changes.
The Nucleon Elastic Form Factors

Physics , 2005, DOI: 10.1016/j.nuclphysa.2005.03.140
Abstract: The nucleon elastic form factors are of fundamental interest, provide a unique testing ground for QCD motivated models of nucleon structure and are of critical importance to our understanding of the electromagnetic properties of nuclei. Even after an experimental effort spanning nearly 50 years the nucleon form factors are still the subject of active investigation. Advances in polarized beams, polarized targets and recoil polarimetry have been exploited over the last decade to produce an important and precise set of data. I review the status of the experimental efforts to measure the nucleon elastic form factors.
The Effect of Angulated Radius Fractures in Forearm Rotation: A Computer Based Model  [PDF]

Journal of Biomedical Science and Engineering (JBiSE) , 2016, DOI: 10.4236/jbise.2016.96024
Abstract: Background: Forearm fractures amongst children are quite a common presentation. The accuracy of correct alignment in forearm bones is important as it determines the degree of forearm rotation (pronation-supination). However in children due to the potential for continuous growth, a degree of angulation is acceptable. The aim of this study was to determine the effect of angulation of forearm fracture on forearm rotation using computer stimulation. Methods: Using a 3D computer modelling software (Wildfire Pro Engineer 4.0, Creo by PTC, Needham, MA), an accurate to scale model of the radius and ulna was replicated from a 7 year old forearm. A realistic representation of pronation/supination of the forearm was applied and a fracture at the junction of proximal one third and distal two third was created. A rotational simulation was created and ended when maximum pronation and supination was reached. Maximum pronation and supination was reached when either no more rotation could occur due to a misalignment of the radius and ulna or there was a collision of the bones. The simulation was repeated in increments of angulation of 2° up to 26°. The angulations that resulted in a combined range of motion (50° pronation and 80° supination) less than 130° were recorded as unacceptable and the others were as acceptable. Findings: The study showed that radius angulation fracture of >16° in the proximal third of the radius would result in an unacceptable reduction of pronation-supination to less than 130°. Conclusion: Patients with more >16° of radius angulation in a distal third shaft fracture of the radius may result in clinical reduction in forearm rotation.
