In recent years, extracorporeal shock wave therapy (ESWT) has received increasing attention for its potential beneficial effects on various bone and soft-tissue pathologies, yielding promising outcomes for pain relief and functional recovery. In fact, ESWT has emerged as an alternative, non-invasive, and safe treatment for the management of numerous musculoskeletal disorders, including myofascial pain syndrome (MPS). In particular, MPS is a common chronic painful condition, accounting for the largest proportion of patients affected by musculoskeletal problems. Remarkably, sensory innervation and nociceptors of the fascial system are emerging to play a pivotal role as pain generators in MPS. At the same time, increasing evidence demonstrates that application of ESWT results in selective loss of sensory unmyelinated nerve fibers, thereby inducing long-lasting analgesia. The findings discussed in the present review are supposed to add novel viewpoints that may further enrich our knowledge on the complex interactions occurring between disorders of the deep fascia including changes in innervation, sensitization of fascial nociceptors, the pathophysiology of chronic musculoskeletal pain of MPS, and EWST-induced analgesia. Moreover, gaining mechanistic insights into the molecular mechanisms of pain-alleviating effects of ESWT may broaden the fields of shock waves clinical practice far beyond the musculoskeletal system or its original application for lithotripsy.

α-Synuclein (α-syn) is a protein involved in neuronal degeneration. However, the family of synucleins has recently been demonstrated to be involved in the mechanisms of oncogenesis by selectively accelerating cellular processes leading to cancer. Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal human cancers, with a specifically high neurotropism. The molecular bases of this biological behavior are currently poorly understood. Here, α-synuclein was analyzed concerning the protein expression in PDAC and the potential association with PDAC neurotropism. Tumor (PDAC) and extra-tumor (extra-PDAC) samples from 20 patients affected by PDAC following pancreatic resections were collected at the General Surgery Unit, University of Pisa. All patients were affected by moderately or poorly differentiated PDAC. The amount of α-syn was compared between tumor and extra-tumor specimen (sampled from non-affected neighboring pancreatic areas) by using in situ immuno-staining with peroxidase anti-α-syn immunohistochemistry, α-syn detection by using Western blotting, and electron microscopy by using α-syn-conjugated immuno-gold particles. All the methods consistently indicate that each PDAC sample possesses a higher amount of α-syn compared with extra-PDAC tissue. Moreover, the expression of α-syn was much higher in those PDAC samples from tumors with perineural infiltration compared with tumors without perineural infiltration.

Ledderhose disease (LD, or plantar fibromatosis) is a rare, nodular, hyperproliferative condition affecting the plantar aponeurosis of the foot. At present, several conservative, non-surgical treatments have been documented, although with various degrees of success, with little evidence in the literature supporting their efficacy. In this scenario, extracorporeal shock wave therapy (ESWT) has emerged as a safe, effective, and less invasive approach for the successful treatment of several refractory musculoskeletal conditions and soft tissue injuries. Again, recent experimental evidence has shown that ESWT can exert beneficial effects on different fibroproliferative diseases, including Dupuytren’s and Peyronie’s disease. In contrast, the literature regarding the use of ESWT for LD is extremely limited, and no optimal application parameters have been defined to ensure its effectiveness for this disease. Therefore, in the present paper, we report a case of a 48-year-old male patient who developed bilateral foot LD, which was successfully treated with a novel ESWT protocol of treatment consisting of three sessions at 1-week intervals, with 2000 impulses at 5 Hz with an energy flux density of 0.20 mJ/mm². Our data show that this ESWT treatment protocol was effective in completely relieving pain, restoring full functional activity, and thus, greatly improving the patient’s quality of life.

Background: Gluteus medius tendinopathy is amongst the most prevalent lower limb tendinopathies and is now recognized as the primary cause of insidious lateral hip pain. Typically affecting middle-aged women, this condition causes disability and reduced quality of life as it negatively impacts most daily life activities. Several studies demonstrate that extracorporeal shockwave therapy is effective in reducing pain and promoting functional recovery in several musculoskeletal disorders including tendinopathies. However, most published data are limited to evaluating focal or radial shockwaves as single interventions. Contrariwise, there is little evidence reporting the use of combined ESWT treatment and outcomes for managing tendon pathologies, and no data are reported on combined ESWT for gluteus medius tendinopathy. Objectives: The aim of this study was to evaluate the clinical outcomes of combined ESWT in gluteus medius tendinopathy. Methods: Medical charts of 11 consecutive patients with gluteal tendinopathy confirmed by ultrasound who underwent a combined ESWT protocol were reviewed. Changes in pain severity and lower limb function were evaluated using the numerical rating scale, the Victorian Institute of Sports Assessment for Gluteal tendinopathy questionnaire, and the Roles and Maudsley score. Clinical outcome measurements were collected at baseline (T0), 2 months after combined ESWT (T1), and at long-term follow-up (T2), at least 10 months post-treatment (mean 26 months). Results: The mean age of the sample was 62.55 ± 3.17 years. A marked prevalence of females was recorded (nine subjects, 81.8%). A significant improvement was observed in all outcome criteria both at short- and long-term follow-up after combined ESWT compared to baseline (p < 0.05). Treatment success rates were 90.9% and 81.8% at T1 and T2, respectively. Conclusions: Combined ESWT is effective and safe for patients with gluteal tendinopathy, with good long-term results in terms of pain relief and improved functional impairment.

Background: Complex regional pain syndrome (CRPS) type 1 is a rare but disabling pain condition, usually involving distal extremities such as the wrist, hand, ankle, and foot due to either direct or indirect traumas. CRPS type 1 is characterized by a complex set of symptoms where no correlation can be identified between the severity of the initial injury and the ensuing painful syndrome. Over the years, numerous treatment strategies have been proposed for CRPS management, but therapies remain controversial. At present, no successful therapeutic intervention exists for this condition. The aim of the present study was to propose and assess the effectiveness of a rehabilitative treatment algorithm for CRPS, which is actually in use at our institution. Methods: We retrospectively reviewed all the patients that underwent physical rehabilitative treatment algorithm for hand CRPS between 2011 and 2017 at our Institution. Results: All the parameters taken into consideration, namely the Purdue Pegboard Test (PPT), Disability of the Arm, Shoulder and Hand (DASH), Visual Analog Scale (VAS), as well hand edema, were significantly improved at the end of the rehabilitation protocol. Conclusions: The results obtained in the present study demonstrated that our rehabilitation protocol was able to achieve substantial improvement in pain and quality of life scores. Thus, an early and skillful rehabilitation intervention is of paramount importance for CPRS type 1 management to achieve a stable and optimal functional recovery while preventing the onset of deformities.

Academic activity is intrinsically composed of two aspects: teaching and research. Since the 20th century, the aphorism “publish or perish” has overwhelmingly established itself in the academic field. Research activity has absorbed more attention from the professors who have neglected teaching activity. In anatomical sciences, research has focused mainly on ultrastructural anatomy and biochemical aspects, far removed from the topics addressed to medical students. Will today’s anatomists be rewarded by their choice? To generate a forecast, we should entrust what history has already taught us. For this analysis, an example was taken, concerning the fate that history reserved for the anatomy teachers of the University of Bologna in the second half of the 16th century. Thanks to Vesalius (1514–1564), experimentation on the human body replaced the old dogmatic knowledge, and didactic innovation was one with research. Some figures were highly praised despite their poor scientific production. The present article focuses on the figure of Flaminio Rota, who was highly esteemed by his colleagues in spite of no significant scientific activity. Reasons for this paradox are examined. Then, history also whispers to us: publish, but without perishing in the oblivion of students.
