What type of mattress should be chosen to avoid back pain and improve sleep quality? Review of the literature
Energy spent during daily activities is recuperated by humans through sleep, ensuring optimal performance on the following day. Sleep disturbances are common: a meta-analysis on sleep quality showed that 15–30% of adults report sleep disorders, such as sleep onset latency (SOL), insufficient duration of sleep and frequently waking up at night. Low back pain (LBP) has been identified as one of the main causes of poor sleep quality. Literature findings are discordant on the type of mattress that might prevent onset of back pain, resulting in an improved quality of sleep. We conducted a systematic literature review of articles published until 2019, investigating the association of different mattresses with sleep quality and low back pain. Based on examined studies, mattresses were classified according to the European Committee for Standardization (2000) as: soft, medium-firm, extra-firm or mattresses customized for patients affected by supine decubitus. A total of 39 qualified articles have been included in the current systematic review. Results of this systematic review show that a medium-firm mattress promotes comfort, sleep quality and rachis alignment
Transient osteoporosis of the hip and subclinical hypothyroidism: an unusual dangerous duet? Case report and pathogenetic hypothesis
Background: Transient osteoporosis of the hip (TOH) is a rare and temporary clinical condition characterised by
bone marrow edema (BME), severe pain, and functional limitation. It commonly occurs in middle-aged men or in
women in the last trimester of pregnancy. TOH usually resolves with conservative therapy but may predispose to
hip fracture or progression to avascular necrosis (AVN). Etiology is still unclear, although several pathophysiological
mechanisms underpinning this condition has been proposed. We describe the management of an unusual case of
TOH occurred in a patient with subclinical hypothyroidism.
Case presentation: A clinical case of a 46-year-old man with severe pain in the left anterior thigh is presented.
After a comprehensive clinical and radiological approach, a TOH was diagnosed. Moreover, biochemical assessment
suggested the presence of subclinical hypothyroidism. After 3 months of treatment with clodronate, physical
therapy and hormone replacement therapy (HRT) a significant improvement of clinical and radiological outcomes
was observed.
Conclusion: Several pathological conditions have been related to development of TOH. In our case, we suggested
for the first time a role of subclinical hypothyroidism as novel contributory factor for the onset of this condition,
providing pathophysiological mechanisms and a scientific rationale for pharmacological treatment

Periprosthetic knee infection: treatment options
Infection is one of the most catastrophic complication following total knee arthroplasty (TKA) and represents the second most common cause of TKA failure. Treatment of a patient with periprosthetic joint infection (PJI) could require often costly and prolonged hospital stays, weeks or months of antibiotic therapy, and multiple surgical procedures. The best management is still highly debating, whereas many treatment options are available. These include suppressive antibiotics, arthroscopic irrigation and debridement, open debridement with insert exchange, single-stage reimplantation and two-stage reimplantation. The choice of the treatment depends on many variables, including integrity of implant, timing of the infection, host factors (age, health, immunologic status), virulence of the infecting organism and wishes of the patient. The aim of this review is to provide a comprehensive understaning of the different options for knee PJIs
Development and Techno-Economic Analysis of an Advanced Recycling Process for Photovoltaic Panels Enabling Polymer Separation and Recovery of Ag and Si
Photovoltaic panels were included in EU Directive as WEEE (Wastes of Electric and
Electronic Equipment) requiring the implementation of dedicated collection schemes and end-of-life
treatment ensuring targets in terms of recycling rate (80%) and recovery rate (85%). Photovoltaic panels
are mainly made up of high-quality solar glass (70–90%), but also metals are present in the frames (Al),
the cell (Si), and metallic contacts (Cu and Ag). According to the panel composition, about $72 per
100 kg of panels can be recovered by entirely recycling the panel metal content. The PhotoLife process
for the treatment of end-of-life photovoltaic panels was demonstrated at pilot scale to recycle high
value glass, Al and Cu scraps. A process upgrade is here reported allowing for polymer separation
and Ag and Si recycling. By this advanced PhotoLife process, 82% recycling rate, 94% recovery rate,
and 75% recoverable value were attained. Simulations demonstrated the economic feasibility of the
process at processing capacity of 30,000 metric ton/y of end-of-life photovoltaic panels
Complex Regional Pain Syndrome Type I Following Non-Orthopedic Surgery: Case Report and Narrative Review
Complex regional pain syndrome type I (CRPS I)—or algodystrophy—is a rare disease
that usually occurs after a traumatic event. It is characterized by typical clinical findings such as
severe and disabling pain disproportionate to the injury, functional limitations, as well as sensory
and vasomotor alterations. However, some people do not report any injury associated with
algodystrophy onset in personal history. We describe the management of an unusual case of CRPS
I which occurred during the long-term follow-up of percutaneous transluminal coronary
angioplasty (PTCA) and performed a narrative review of algodystrophy in non-orthopedic surgery.
A clinical case of a 44-year-old man with a spontaneous onset of CRPS I of the right ankle is
presented. He did not refer to history of any memorable significant trigger event. Approximately 5
months before the onset of clinical manifestations, he received a PTCA via the right femoral
approach. We suppose an association between CRPS and this procedure and propose a possible
pathophysiologic mechanism. The patient was treated with intramuscular neridronate, which
resulted in significant pain relief and improved his quality of life. A comprehensive clinical and
instrumental evaluation in patients with CRPS is challenging but mandatory for a correct diagnosis.
An extensive analysis of patient history is important for identifying any potential trigger event,
including non-orthopedic procedures. Bone scan could have a pivotal role for improving diagnostic
sensitivity and specificity in CRPS I. Neridronate was a safe and effective therapeutic approach for
this patient, confirming the results of the high-quality evidence availabl
Atypical periprosthetic femoral fractures of the hip: A PRISMA compliant systematic review
Introduction: Long-term use of bisphosphonates (BPs) is associated with Atypical Femoral Fracture (AFF). Theoretically, periprosthetic femoral fractures (PFF) should be excluded from the diagnosis of AFF. How-ever, recently several studies reported the occurrence of PPFs around a hip arthroplasty presenting fea-tures of an AFF. The present study describes the characteristics of Atypical Periprosthetic Femoral Fracture (APFF) and evaluates the effectiveness of their management through a PRISMA compliant systematic re-view of the published case reports and series. Materials and methods: A literature search was performed using "periprosthetic fracture" and "atypical femoral fracture" as keywords. Patients demographics, drug use, clinical and imaging characteristics, stem fixation and classification, management strategies for APFF and patients' outcomes, were also collected. Results: The present review included and analysed 17 patients from 12 studies. All APFFs occurred in females with a mean age of 75.9 years of age (range 43-87). In 11 patients, APFFs occurred around an uncemented stem, and in 6 around a cemented stem. Ten fractures were incomplete, and 7 complete. Conservative management was effective in 4 of 10 patients with incomplete fracture, while all patients with complete fractures underwent open reduction and internal fixation. A fracture non-union was ob-served in 5 patients and further surgery was required. Discussions: APFFs share several clinical and imaging characteristics with AFF. An appropriate and early diagnosis may allow to improve the outcome of these fractures, the management of which should be based on the same principles of that of AFFs. Conclusions: Considering the low quality of published articles and the heterogeneity of the treatment used, a clear recommendation of the most appropriate treatment cannot be formulated.

Characterization of neuropathic component of back pain in patients with osteoporotic vertebral fractures
BACKGROUND: Osteoporotic vertebral fractures (OVFs) are often followed by chronic back pain which may have a nociceptive, neuropathic, or mixed component. However, literature on this topic is lacking.
OBJECTIVE: The objective of this cross-sectional study is to characterize the neuropathic component of chronic back pain in patients with OVFs.
METHODS: Spine fractures were detected by morphometric examination. Pain severity and its impact on daily living activities (ADL) were evaluated through the Brief Pain Inventory (BPI). Neuropathic pain was investigated through the Italian Versions of the Leeds Assessment of Neuropathic Symptoms and Signs pain scale (LANSS) and the painDETECT questionnaire (PD-Q).
RESULTS: We included 72 patients, mainly women (88.8%), with mean age of 69.2 years. The 70.8% of patients had multiple OVFs, of which 47% located at the thoracic spine, 43.1% at the thoracic and at lumbar spine, and 9.8% at the lumbar spine. The BPI showed moderate back pain in 23.6% of cases and severe in 8.3% of cases, with high interference with ADL in 38.9% of patients. The PD-Q revealed the presence of neuropathic pain in 5.5% of cases, while the S-LANSS in 23.6% of cases.
CONCLUSIONS: In our study, the prevalence of neuropathic component of chronic back pain ranged from 5.5% to 23.6%, according to PD-Q and LANSS respectively, in patients with OVFs. Further studies should investigate if the characterization of chronic back pain might contribute to appropriateness of interventions for this population
The Role of Hyaluronic Acid in Sport-Related Tendinopathies: A Narrative Review
Tendinopathy is a complex clinical condition with a rising incidence and prevalence, particularly during sports practice. For the return to play in affected patients, adequate functional and structural recovery of the tendon is the ultimate goal, avoiding the high risk of recurrence. In this perspective, local therapies alongside exercise are showing promising results. Despite evidence suggesting hyaluronic acid (HA) injections as effective in the treatment of tendinopathy, current recommendations about the management of this condition do not include this intervention. HA seems to be an effective therapeutic option for the management of sport-related tendinopathies, but further studies with a larger sample size are needed to confirm available findings. In this narrative review, we analyzed available literature about the rationale of the use of HA in the management of tendon injury and, particularly, in sport-related tendinopathies
Low-Intensity Pulsed Ultrasound in the Treatment of Nonunions and Fresh Fractures: A Case Series
It is estimated that approximately 5% to 10% of fractures will evolve into nonunions. Nonunions have a significant impact on patient quality of life and on socioeconomic costs. Low-intensity pulsed ultrasound (LIPUS) is a non-invasive therapy widely used within the orthopedic community to accelerate the healing of fresh fractures, to minimize delayed healing, and to promote healing of nonunions. In this case series, 46 nonunions and 19 fresh fractures were treated with LIPUS for at least three months or until fracture healing. Bone healing was assessed both at a radiological and a functional level. Of the nonunions healed, 89% had a mean healing time of 89 ± 53 days. In the group of fresh fractures, the healing percentage was 95% with a mean healing time of 46 ± 28 days. LIPUS treatment is proven to be safe and well tolerated; there were no adverse events related to the use of the device, even in the presence of internal fixations and infections. LIPUS therapy should be considered a low-risk option both as an adjunct to surgery or as a standalone therapy in the management of nonunion and fresh fractures
