Free-flap salvage of soft tissue complications following the lateral approach to the calcaneus.
Soft tissue complications including wound slough and/or infection after lateral foot incisions used to approach the calcaneus are notoriously frequent. Simpler wound management may be possible when early, aggressive treatment is deployed. If definitive coverage has been delayed, local options typically become unreliable. Free tissue transfers may then become the mainstay for limb salvage. Over the past 2 decades in our joint experience in managing such complications referred to us, 8 free flaps were necessary in 7 patients who all had had some form of traumatic injury to the calcaneus. The mean interval from wound compromise to coverage was an exceedingly long 88.1 days (range: 29-166 days). The gracilis muscle was our choice for tissue transfer in every patient as this is a versatile, thin, yet wide-enough muscle with a pedicle length satisfactory to allow reach to nearby recipient sites. There were no flap-related untoward events, with all completely surviving. The anterior tibial/dorsalis pedis axis served as the usual recipient site (87.5%) for microanastomosis. Fixation hardware was retained whenever possible. All limbs were ultimately salvaged to allow reasonable ambulation
The United Nations Security Council and the enforcement of international humanitarian law
This Article discusses the competences and powers of the UN Security Council in securing compliance with international humanitarian law, in particular through the adoption of the measures provided in Chapter VII of the Charter: The competence of the Council in this field can be founded on several legal grounds: on a broad interpretation of the notion of “threat to the peace” (Article 39 of the Charter), on Article 94(2) with regard to the International Court of Justice's judgments establishing violations of the jus in bello and also on the customary duty to ensure respect for international humanitarian law as reflected in Article 1 Common to the 1949 Geneva Conventions on the Protection of the Victims of War. In particular, such customary provision empowers the Security Council to react to any violation of international humanitarian law regardless of a nexus with concerns of international stability. Although the Council has adopted a variety of measures in relation to violations of the laws of war, the most incisive ones are those provided in Articles 41 and 42 of Chapter VII, which however are not without problems. The role the Security Council has played in the enforcement of international humanitarian law has been criticized because of its selective and opportunistic approach, which is due to the political nature of the organ. Also, in several instances the Council, far from securing compliance with the jus in bello, has instead interfered with its application. However selective and imperfect the Council's approach might be, though, its power to adopt decisions binding on UN members and its competence to take or authorize coercive measures involving the use of force make it potentially a formidable instrument against serious violations of international humanitarian law, partly remedying the lack of enforcing mechanisms in the treaties on the laws of war

International organisations and anti-terrorist sanctions: no accountability for human rights violations?
The targeted sanctions adopted by the UN Security Council against individuals and entities suspected of association with terrorism are managed through procedures that infringe fundamental human rights, and there are no mechanisms for actual accountability. With the exception of the ECJ in Kadi, municipal and regional courts tend to consider the UN Security Council's resolutions and domestic measures implementing them outside the scope of judicial review. This article argues that the Security Council is bound to observe human rights even in the context of international security action, and that States are not exonerated from international responsibility for violations committed under the umbrella of Chapter VII resolutions
Effect of cross exercise on quadriceps acceleration reaction time and subjective scores (Lysholm questionnaire) following anterior cruciate ligament reconstruction
Abstract Background Anterior cruciate ligament (ACL) injury or reconstruction can cause knee impairments and disability. Knee impairments are related to quadriceps performance – accelerated reaction time (ART) – and disability to performance of daily living activities which is assessed by questionnaires such as the Lysholm knee score. The purposes of this study were to investigate the effect of cross exercise, as supplementary rehabilitation to the early phase of ACL reconstruction: a) on quadriceps ART at the angles 45°, 60° and 90° of knee flexion and, b) on the subjective scores of disability in ACL reconstructed patients. Methods 42 patients who underwent ACL reconstruction were randomly divided into 3 groups, two experimental and one control. All groups followed the same rehabilitation program. The experimental groups followed 8 weeks of cross eccentric exercise (CEE) on the uninjured knee; 3 d/w, and 5 d/w respectively. Quadriceps ART was measured at 45°, 60° and 90° of knee flexion pre and nine weeks post-operatively using an isokinetic dynamometer. Patients also completed pre and post operatively the Lysholm questionnaire whereby subjective scores were recorded. Results Two factor ANOVA showed significant differences in ART at 90° among the groups (F = 4.29, p = 0.02, p Significant differences were also found in the Lysholm score among the groups (F = 4.75, p = 0.01, p Conclusion CEE showed improvements on quadriceps ART at 90° at a sequence of 3 d/w and in the Lysholm score at a sequence of 3 d/w and 5 d/w respectively on ACL reconstructed patients.</p
Reproducibility of a peripheral quantitative computed tomography scan protocol to measure the material properties of the second metatarsal
Background: Peripheral quantitative computed tomography (pQCT) is an established technology that allows for the measurement of the material properties of bone. Alterations to bone architecture are associated with an increased risk of fracture. Further pQCT research is necessary to identify regions of interest that are prone to fracture risk in people with chronic diseases. The second metatarsal is a common site for the development of insufficiency fractures, and as such the aim of this study was to assess the reproducibility of a novel scanning protocol of the second metatarsal using pQCT. Methods. Eleven embalmed cadaveric leg specimens were scanned six times; three times with and without repositioning. Each foot was positioned on a custom-designed acrylic foot plate to permit unimpeded scans of the region of interest. Sixty-six scans were obtained at 15% (distal) and 50% (mid shaft) of the second metatarsal. Voxel size and scan speed were reduced to 0.40 mm and 25 mm.sec-1. The reference line was positioned at the most distal portion of the 2nd metatarsal. Repeated measurements of six key variables related to bone properties were subject to reproducibility testing. Data were log transformed and reproducibility of scans were assessed using intraclass correlation coefficients (ICC) and coefficients of variation (CV%). Results: Reproducibility of the measurements without repositioning were estimated as: trabecular area (ICC 0.95; CV% 2.4), trabecular density (ICC 0.98; CV% 3.0), Strength Strain Index (SSI) - distal (ICC 0.99; CV% 5.6), cortical area (ICC 1.0; CV% 1.5), cortical density (ICC 0.99; CV% 0.1), SSI - mid shaft (ICC 1.0; CV% 2.4). Reproducibility of the measurements after repositioning were estimated as: trabecular area (ICC 0.96; CV% 2.4), trabecular density (ICC 0.98; CV% 2.8), SSI - distal (ICC 1.0; CV% 3.5), cortical area (ICC 0.99; CV%2.4), cortical density (ICC 0.98; CV% 0.8), SSI - mid shaft (ICC 0.99; CV% 3.2). Conclusions: The scanning protocol generated excellent reproducibility for key bone properties measured at the distal and mid-shaft regions of the 2 nd metatarsal. This protocol extends the capabilities of pQCT to evaluate bone quality in people who may be at an increased risk of metatarsal insufficiency fractures
in keeping with the spirit of the albertine statute constitutionalisation of the national unification
This chapter deals with the difficult process of constitutionalisation which characterised Italian Unification. Constitutionalisation is a long-term phenomenon which had the purpose of giving constitutional forms to the Nation. The promulgation of the Albertine Statute is more the start than the arrival of this phenomenon. The focus of this investigation is, therefore, to study the Constitution through its evolution paying particular attention to the process of legal integration within the structures of the Albertine Statute and to the amendment mechanisms of the constitutional text. The preamble of the Albertine Statute speaks of «perpetual and irrevocable fundamental law». The word «perpetual» meant the prohibition of revoking constitutional concession, while the word «irrevocable» was intended as a pact between the Sovereign and the Nation. Over the years, very few were the changes to the letter of the Albertine Statute. The interpretation and the practice represented the most important mechanisms of constitutional change (implicit constitutional changes). A primary role was acknowledged to non-written norms. In this perspective, it may well be said that the Italian Constitution consisted in something more than the written text and dwelt in the spirit and not in the letter of the Albertine Statute
