    Calcific tendinopathy of supraspinatus tendon in elite volleyball players: A point-of-care ultrasound diagnosis

    In overhead sports like volleyball, the onset of a rotator cuff tendinopathy due to functional overload is a not uncommon observation. Herein, we present the case of a symptomatic calcific tendinopathy involving the supraspinatus tendon with a subacromial impingement syndrome in a young elite volleyball player. Shoulder and supraspinatus tendon evaluation with static and dynamic ultrasonography (US) can assist in the rapid diagnosis of tendinopathy. Thus, sports physicians must be aware of this in order to expedite rapid referral to a musculoskeletal specialist who can perform a point-of-care US examination of the shoulder. This approach to sports pathology potentially improves patient outcomes

    COVID-19 pandemic as a watershed moment: A call for systematic psychological health care for frontline medical staff

    : The COVID-19 pandemic is producing a huge health care burden with millions of cases and thousands of deaths. The coronavirus' high virulence and contagiousness and the frequent sudden onset of illness is overwhelming critical care and frontline healthcare staff. Frontline professionals are exposed to unprecedented levels of intensive existential threat requiring systematic, specialized psychological intervention and support. New psychological services need to be urgently implemented to manage the mental healthcare needs of frontline medical staff working with patients with COVID-19. The COVID-19 pandemic is a watershed moment: health care systems universally require a step-change to improve our preparedness for future pandemics

    Anti-HPV vaccination in women treated for HPV-related lesions: effective vaccination strategy for achieving HPV-related diseases control

    Get PDF
    Human Papillomavirus (HPV) vaccination is able to reduce the risk of relapse in women undergoing surgery for HPVrelated lesions. The surgical treatment of these lesions can correlate with a greater risk of preterm parts. The extension of the recommendation of HPV vaccination to patients treated for a previous HPV-related lesion would entail a lower expense for the Health System. Therefore, an increase in the use of HPV vaccination is desirable also in this target population as well as the implementation of a care pathway dedicated to women treated for HPV lesions that includes vaccination in the prevention activities of relapses

    Toward autonomous robotic prostate biopsy: a pilot study

    Purpose We present the validation of PROST, a robotic device for prostate biopsy. PROST is designed to minimize human error by introducing some autonomy in the execution of the key steps of the procedure, i.e., target selection, image fusion and needle positioning. The robot allows executing a targeted biopsy through ultrasound (US) guidance and fusion with magnetic resonance (MR) images, where the target was defined. Methods PROST is a parallel robot with 4 degrees of freedom (DOF) to orient the needle and 1 DOF to rotate the US probe. We reached a calibration error of less than 2 mm, computed as the difference between the needle positioning in robot coordinates and in the US image. The autonomy of the robot is given by the image analysis software, which employs deep learning techniques, the integrated image fusion algorithms and automatic computation of the needle trajectory. For safety reasons, the insertion of the needle is assigned to the doctor. Results System performance was evaluated in terms of positioning accuracy. Tests were performed on a 3D printed object with nine 2-mm spherical targets and on an anatomical commercial phantom that simulates human prostate with three lesions and the surrounding structures. The average accuracy reached in the laboratory experiments was 1.30 ± 0.44 mm in the first test and 1.54 ± 0.34 mm in the second test. Conclusions We introduced a first prototype of a prostate biopsy robot that has the potential to increase the detection of clinically significant prostate cancer and, by including some level of autonomy, to simplify the procedure, to reduce human errors and shorten training time. The use of a robot for the biopsy of the prostate will create the possibility to include also a treatment, such as focal ablation, to be delivered through the same system

    Inside the "African Cattle Complex": Animal Burials in the Holocene Central Sahara

    Get PDF
    Cattle pastoralism is an important trait of African cultures. Ethnographic studies describe the central role played by domestic cattle within many societies, highlighting its social and ideological values well beyond its mere function as 'walking larder'. Historical depth of this African legacy has been repeatedly assessed in an archaeological perspective, mostly emphasizing a continental vision. Nevertheless, in- depth site-specific studies, with a few exceptions, are lacking. Despite the long tradition of a multi-disciplinary approach to the analysis of pastoral systems in Africa, rarely do early and middle Holocene archaeological contexts feature in the same area the combination of settlement, ceremonial and rock art features so as to be multi- dimensionally explored: the Messak plateau in the Libyan central Sahara represents an outstanding exception. Known for its rich Pleistocene occupation and abundant Holocene rock art, the region, through our research, has also shown to preserve the material evidence of a complex ritual dated to the Middle Pastoral (6080-5120 BP or 5200-3800 BC). This was centred on the frequent deposition in stone monuments of disarticulated animal remains, mostly cattle. Animal burials are known also from other African contexts, but regional extent of the phenomenon, state of preservation of monuments, and associated rock art makes the Messak case unique. GIS analysis, excavation data, radiocarbon dating, zooarchaeological and isotopic (Sr, C, O) analyses of animal remains and botanical data are used to explore this highly formalized ritual and lifestyles of a pastoral community in the Holocene Sahara
