Background: Dislocation of both ends of the clavicle is a rare traumatic lesion and the mechanism of the lesion is usually related to major trauma. The first case was described in 1831. Case Description: We present the oldest referenced case of this alteration. The skeleton studied belonged to an old woman buried inside the Sant Pere de Madrona Church in Berga (Barcelona/Spain) and its dating indicated it corresponded to the end of the 17th century. There was a pseudarthrosis between the clavicle and coracoid ligament; when the bones were reconstructed by pseudarthrosis both ends of the clavicle appeared dislocated. Literature Review: Bipolar dislocation of both ends of the clavicle, or "floating-clavicle", is a rare injury. Since 1831 when this type of injury was first reported, approximately 40 cases have been published. No archaeological case has been published. Clinical Relevance: Despite experiencing bipolar dislocation of both ends of the clavicle, or floating-clavicle, it is possible to have acceptable function of the arm as suggested by the anthropologic parameters analyzed here. The head of the humerus of the affected shoulder shows no abnormalities and the contralateral glenoid cavity shows severe osteochondritis of the anteroinferior side. © 2011 The Association of Bone and Joint Surgeons®.

Pectus excavatum (PE) is the most common congenital chest wall deformity. It consists of a concavity of the sternum, and the costal cartilages derived from an unbalanced growth of the costochondral regions of the anterior chest wall. The standard operative treatment for PE has been the Ravitch procedure. This technique requires a long incision in the anterior chest wall and bilateral resection of the affected costal cartilages, needing in most cases a posterior metal bar support. The belief that the treatment of PE is basically esthetic led Donald Nuss to develop in 1998 a minimally invasive surgical treatment based on the skeletal frame plasticity and reshape capacity applied to the thorax. Thereby he deviced a technique involving a retrosternal steel bar modifying the sternum's concavity and supporting the shape of the amended thorax, all performed through two small incisions at each side of the thorax with the help of a thoracoscope. The bar is maintained from 2 to 3 years, and removed after this period. This procedure obtains >90% of positive results with significant esthetic improvement and patient satisfaction. This minimally surgical approach for PE is to be discussed in this review. © 2016 Edizioni Minerva Medica.

Activation of vasa vasorum (the microvessels supplying the major arteries) at specific sites in the adventitia initiates their proliferation or 'angiogenesis' concomitant with development of atherosclerotic plaques. Haemorrhagic, leaky blood vessels from unstable plaques proliferate abnormally, are of relatively large calibre but are immature neovessels poorly invested with smooth muscle cells and possess structural weaknesses which may contribute to instability of the plaque by facilitation of inflammatory cell infiltration and haemorrhagic complications. Weak neovascular beds in plaque intima as well as activated adventitial blood vessels are potential targets for molecular imaging and targeted drug therapy, however, the majority of tested, currently available imaging and therapeutic agents have been unsuccessful because of their limited capacity to reach and remain stably within the target tissue or cells in vivo. Nanoparticle technology together with magnetic resonance imaging has allowed the possibility of imaging of neovessels in coronary or carotid plaques, and infusion of nanoparticle suspensions using infusion catheters or implant-based drug delivery represents a novel and potentially much more efficient option for treatment. This review will describe the importance of angiogenesis in mediation of plaque growth and development of plaque instability and go on to investigate the possibility of future design of superparamagnetic/perfluorocarbon-derived nanoparticles for imaging of the vasculature in this disease or which could be directed to the adventitial vasa vasorum or indeed intimal microvessels and which can release active payloads directed against primary key external mitogens and intracellular signalling molecules in endothelial cells responsible for their activation with a view to inhibition of angiogenesis. © 2010 The Royal Society of Chemistry.

Ancient DNA (aDNA) analysis can be a useful tool in bacterial disease diagnosis in human remains. However, while the recovery of Mycobacterium spp. has been widely successful, several authors report unsuccessful results regarding ancient treponemal DNA, casting doubts on the usefulness of this technique for the diagnosis of ancient syphilis. Here, we present results from an analysis of four newborn specimens recovered from the crypt of "La Ermita de la Soledad" (XVI-XVII centuries), located in the province of Huelva in the southwest of Spain. We extracted and analyzed aDNA in three independent laboratories, following specific procedures generally practiced in the aDNA field, including cloning of the amplified DNA fragments and sequencing of several clones. This is the most ancient case, reported to date, from which detection of DNA from T. pallidum subspecies pallidum has been successful in more than one individual, and we put forward a hypothesis to explain this result, taking into account the course of the disease in neonate individuals. © 2012 Montiel et al.

Background: Cardiovascular risk factors, clinical features and early outcome of first-ever cerebral lacunar infarcts from 1986 to 2004, using the Sagrat Cor Hospital of Barcelona Stroke Registry, were assessed and compared with data from patients with nonlacunar infarction. Methods: The study population consisted of 566 patients with lacunar infarct and 1,516 patients with nonlacunar infarct. Secular trends for the periods 1986-1992, 1993-1998 and 1999-2004 were analyzed. Results: Age and the percentage of very old patients (≥85 years old) increased significantly (p < 0.001) throughout the time period. There was a significant decrease in the percentage of patients with hypertension, but the percentage of patients with chronic obstructive pulmonary disease increased. The use of brain magnetic resonance imaging (MRI) also increased significantly. The median length of hospital stay decreased significantly. Conclusions: Significant changes over a 19-year period included an increase in the patients' age, frequency of very old patients (≥85 years old) and use of MRI studies, whereas the frequency of hypertension and length of hospital stay decreased.
