    Introduction and purpose: Patellar tendinopathy is a disease affecting particularly athletes. Platelet-rich plasma (PRP) injections have gained increasing interest for their potential benefits. Anyway, a tendon disease longer than 6 months should be considered as an indication for surgery. The aim of our study was to evaluate the efficacy of PRP in athletes with a severe chronic patellar tendinopathy longer than 6 months when surgery should be chosen. Methods: We enrolled 17 sport practitioners (19 patellar tendons) who did not want to undergo surgery and who are nonresponders to other conservative treatments. We treated them with PRP and calculated the results using the visual analog scale (VAS), the Victorian Institute of Sport Assessment-Patellar (VISA-P) score, and Tegner Activity Scale. Every test has been conducted at T0, T1 (4 months), and T2 (12 months). Results: We found a poor improvement at T1 and a clinical worsening at T2 through VAS. VISA-P showed a medium improvement both at T1 and T2. Tegner scale did not show improvements. Conclusions: Our study was not able to remove the doubts about the benefits of PRP in patellar tendinopathy, confirming ambiguous certainties. Further investigations are needed to assess its effectiveness

    Background: Mortality rates for patients with ARDS remain high. We assessed temporal changes in the epidemiology and management of ARDS patients requiring invasive mechanical ventilation in European ICUs. We also investigated the association between ventilatory settings and outcome in these patients. Methods: This was a post hoc analysis of two cohorts of adult ICU patients admitted between May 1–15, 2002 (SOAP study, n = 3147), and May 8–18, 2012 (ICON audit, n = 4601 admitted to ICUs in the same 24 countries as the SOAP study). ARDS was defined retrospectively using the Berlin definitions. Values of tidal volume, PEEP, plateau pressure, and FiO2 corresponding to the most abnormal value of arterial PO2 were recorded prospectively every 24 h. In both studies, patients were followed for outcome until death, hospital discharge or for 60 days. Results: The frequency of ARDS requiring mechanical ventilation during the ICU stay was similar in SOAP and ICON (327[10.4%] vs. 494[10.7%], p = 0.793). The diagnosis of ARDS was established at a median of 3 (IQ: 1–7) days after admission in SOAP and 2 (1–6) days in ICON. Within 24 h of diagnosis, ARDS was mild in 244 (29.7%), moderate in 388 (47.3%), and severe in 189 (23.0%) patients. In patients with ARDS, tidal volumes were lower in the later (ICON) than in the earlier (SOAP) cohort. Plateau and driving pressures were also lower in ICON than in SOAP. ICU (134[41.1%] vs 179[36.9%]) and hospital (151[46.2%] vs 212[44.4%]) mortality rates in patients with ARDS were similar in SOAP and ICON. High plateau pressure (> 29 cmH2O) and driving pressure (> 14 cmH2O) on the first day of mechanical ventilation but not tidal volume (> 8 ml/kg predicted body weight [PBW]) were independently associated with a higher risk of in-hospital death. Conclusion: The frequency of and outcome from ARDS remained relatively stable between 2002 and 2012. Plateau pressure > 29 cmH2O and driving pressure > 14 cmH2O on the first day of mechanical ventilation but not tidal volume > 8 ml/kg PBW were independently associated with a higher risk of death. These data highlight the continued burden of ARDS and provide hypothesis-generating data for the design of future studies

Ortopedia e Traumatologia Università di Perugia. Ospedale S.Maria della Misericordia, 06100 Perugia, Italy; 3Department of Medicine, Sezione di Clinica Medica e Anatomia Patologia, 05100 Terni, ItalyAbstract: Chronic pain is a major health-care problem worldwide, affecting more than one out of five adults in Europe. Although multiple analgesic agents have been extensively investigated in terms of clinical response and tolerability profile, few studies have focused on the impact of these therapies on patients’ quality of life (QoL). Of note, improvement in QoL, together with functional recovery, has been recognized since the late 1990s as two main goals of analgesic therapy. Tapentadol is a novel analgesic molecule that synergistically combines two mechanisms of action, μ-opioid receptor agonism and norepinephrine reuptake inhibition, and for which multiple literature data are available that confirm its efficacy and safety in controlling pain. This narrative review summarizes the information available on the impact of tapentadol on QoL, with the aim to provide clinicians with a comprehensive overview of the analgesic effects of tapentadol prolonged release beyond the reduction of pain.Keywords: pain, quality of life, tapentado

    Giuseppe Rinonapoli,1 Stefano Coaccioli,2 Lorenzo Panella31Dipartimento di Scienze Chirurgiche, s.c. Ortopedia e Traumatologia Università di Perugia, Ospedale S. Maria della Misericordia, 06100 Perugia, Italy; 2Department of Medicine, Sezione di Clinica Medica e Anatomia Patologia, Terni, Italy; 3Rehabilitation Department, ASST Pini-CTO, Milan, ItalyAbstract: Osteoarthritis (OA) is the most prevalent joint disease in older people worldwide. Pain owing to OA is considered one of the most frequent causes of chronic pain; however, current pharmacological approaches have some limitations in terms of efficacy and safety. Of note, descending inhibitory pain pathways are often disrupted in chronic OA pain, and pharmacotherapies targeting those pathways – eg, those that block norepinephrine reuptake may be more appropriate for managing chronic pain than pure μ-opioid receptor (MOR) agonists. Tapentadol is an analgesic molecule, which combines two synergistic mechanisms of action, MOR, and norepinephrine reuptake inhibition. This narrative review will briefly discuss the mechanisms contributing to the onset and maintenance of pain in OA patients; clinical data on the use of tapentadol in this setting will then be presented and commented.Keywords: osteoarthritis, pain, tapentado

    A Fatal Sepsis Caused by Hyaluronate Knee Injection: How Much the Medical History and the Informed Consent Might Be Important?

    The incidence of Osteoarthritis (OA) is gradually increasing worldwide due to two main reasons: longer life expectation and increased functional demand. Several treatment options have been proposed for this disease. Conservative treatment has the goal to improve the quality of life, reduce pain, and prevent the progression of the disease. Hyaluronate viscosupplementation is one of the most used infiltrative treatments for OA, but, despite its common use, clinical efficacy is still under question. Though adverse reactions for this medical option are actually rare, septic arthritis is a very scaring complication. We present a case report of a 59-year-old man who has been submitted to only one knee hyaluronate injection and consequently reported a severe septic arthritis and systemic sepsis, which lead to the death of the patient. We recommend producing correct guidelines for a clean aseptic procedure of injection to obtain proper consensus from the patient and to pay attention to his clinical history and comorbidities before acting any kind of invasive treatment, including joint injection

    Modulation of sensitization processes in the management of pain and the importance of descending pathways: a role for tapentadol?

    Objective: This paper presents and discusses recent evidence on the pathophysiological mechanisms of pain. The role of tapentadol\u2013an opioid characterized by an innovative mechanism of action (i.e. \ub5-opioid receptor [MOR] agonism and inhibition of noradrenaline [NA] reuptake [NRI])\u2013in the modulation of pain, and the most recent pharmacological evidence on this molecule (e.g. the \ub5-load concept) are also presented and commented upon. Methods: Narrative review. Results: Solid evidence has highlighted the importance of central sensitization in the transition from acute to chronic pain. In particular, the noradrenergic system holds a major role in limiting central sensitization and the progression to chronic pain. Therefore, pharmacological modulation of the noradrenergic system appears to be a well-grounded strategy for the control of chronic pain. Tapentadol is characterized by a to-date-unique mechanism of action, since it acts both as a MOR agonist and as an inhibitor of NA reuptake. The synergistic interaction of these two mechanisms allows a strong analgesic effect by acting on both ascending and descending pathways. Of note, the reduced \ub5-load of tapentadol limits the risk of opioid-related adverse events, such as gastrointestinal disturbances. Moreover, the NA component becomes predominant, at least, in some types of pain, with consequent specific clinical efficacy in the treatment of neuropathic and chronic pain. Conclusions: According to these characteristics, tapentadol appears suitable in the treatment of severe uncontrolled chronic pain characterized by both a nociceptive and a neuropathic component, such as osteoarthritis or back pain
