Medical management of osteoarthritis during the CO-VID-19 pandemic: a challenge for the present and the future.

Abstract: The ongoing Covid-19 pandemic has inevitably changed the treatment of many chronic diseases which has been suspended or has suffered dangerous slowdowns. Osteoarthritis (OA) is the most common musculoskeletal disease. As a result, the medical management of Osteoarthritis was heavily impacted by the pandemic, and it required new therapeutic strategies. The purpose of this descriptive review is to provide an overview of how much the pandemic has affected the medical management of osteoarthritis and to outline a number of possible countermeasures. The COVID-19 pandemic requires a "multimodal approach": physicians are called to test the management of Osteoarthritis patients at a distance, through the tools made available by telemedicine, for all cases in which direct contact is avoidable. Therapies that instead require a direct intervention on the patient impose that all the procedures are carried out in complete safety, scrupulously keeping to the use of personal protective equipements.

Impact of Covid-19 pandemic on injection-based practice: report from an Italian multicenter and multidisciplinary survey.

Background: There are no papers exploring the impact of COVID-19 pandemic on the injection-based practice in patients affected by different rheumatic diseases, including osteoarthritis. The aim was to investigate the impact of COVID-19 pandemic on injection-based practice trough the Italian country. Study design: A survey-based retrospective cross-sectional study. Methods: An Italian-language questionnaire was developed by a group of senior researchers and distributed by e-mail to some Rheumatology, Orthopedic and Rehabilitation Units from different geographic areas of Italy. The survey included information about the number of injections performed during COVID-19 pandemic (stratified by injected agents and injected joint), in comparison to the pre-pandemic period, and the possible reasons behind an eventual reduction. Responses were collected and descriptive analysis calculated. Results: Eleven centers of the National Health Service completed the survey. The activities of the injections services significantly decreased across the country with a percentage of reduction of 60% compared to the pre-pandemic period. A significant reduction of both intra-articular and peri-articular injections was registered. Among intra-articular. treatments, the most affected ones were the hyaluronic acid injections, when compared to corticosteroids. A significant decrease of the total amount of peri-articular injections was observed. The strict government restrictions and the fear of patients to become infected represented the most limiting factors. Conclusions: The reported decrease of the injection-based practice in our country during the COVID-19 pandemic highlights the detrimental effects of the COVID-19 pandemic on the management of chronic musculoskeletal diseases with possible negative consequences in terms of disability and quality of life.

Idiopathic facial palsy: umbrella review of systematic reviews and meta-analyses.

Idiopathic facial palsy is the most common disease of the VII cranial nerve. There are many treatments to facilitate recovery from this condition: pharmacological, surgical, rehabilitative, but the effectiveness of some of these treatments, especially the latter, is still under discussion. The purpose of this umbrella review of systematic reviews is to analyse the literature in order to investigate the different rehabilitation interventions in patients suffering from idiopathic facial palsy. A scientific literature search was carried out from January 2009 until August 2019, using Mesh the terms "facial palsy", "Bell's Palsy", "idiopathic facial nerve palsy", combined with "rehabilitation" and "therapy". Initially all the systematic reviews and meta-analyses of the last 10 years concerning rehabilitation treatments for the recovery of injured functions in facial palsy were included. Given the heterogeneity of the studies in the literature, which do not differentiate the different causes of facial palsy, all the causes of idiopathic facial palsy were included in the review. The research resulted in 94 published systematic reviews but only 6 were considered in respect to the inclusion criteria. All studies agree on the lack of high-quality scientific work to be able to say that Bell's physiotherapy treatments for facial palsy are effective, in particular with regard to recovery times during the rehabilitation process. Future studies are needed, in order to highlight the therapeutic implications of the different rehabilitation methods, with standardized protocols, in patients suffering from facial palsy of different aetiology.

Trade-Offs with rehabilitation Effectiveness (REs) and Efficiency (REy) in a sample of Italian disabled persons in a in post-acuity rehabilitation unit.

BACKGROUND: Intensive Rehabilitation Centres, known in Italy as "code 56", admit patients who need to recover from an acute episode. Different Rehabilitation Impact Indices have been proposed as composite rehabilitation outcomes measuring the rate of improvement due to a rehabilitation program. The most widely employed measure the performance of Activities of daily living in rehabilitation is the modified Barthel Index. The Barthel Index-based Rehabilitation Impact Indices are the Rehabilitation Effectiveness and the Rehabilitation Efficiency. AIM: The aim of our study was to evaluate the trade-off between Rehabilitation Effectiveness tayand Rehabilitation Efficiency with respect to the Barthel Index admission score and the Length Of Stay, and their ideal ranges that optimized both indices. METHODS: We retrospectively evaluated data of all patients admitted to intensive rehabilitation unit of the Scientific Institute for Research and Healthcare San Raffaele Pisana of Rome, from January 2006 to March 2018. The primary outcome measures of our study were patient's Rehabilitation Effectiveness and Rehabilitation Efficiency during the hospital stay. RESULTS: A database of 3,466 patients was analysed and the Rehabilitation Effectiveness and Rehabilitation Efficiency indexes were calculated. We calculated the median rank ratio of the Rehabilitation Effectiveness to the Rehabilitation Efficiency against Barthel Index scores. We calculated the median rank ratio of the Rehabilitation Effectiveness to Rehabilitation Efficiency against Barthel Index scores and days of stay. The median rank ratio of the Rehabilitation Effectiveness to the Rehabilitation Efficiency value were 1 in the range of Barthel Index scores from 32 to 42. The median rank ratio of the Rehabilitation Effectiveness to Rehabilitation Efficiency value were 1 for a Length of Stay corresponding to 33 days. CONCLUSIONS: In our study we calculated the Trade-offs between Rehabilitation Effectiveness and Rehabilitation Efficiency with respect to admission Barthel Index Score and Length Of Stay in a population of 3,466 patients affected by orthopedic (1,707) and neurological (1,759) diseases. Every member of the healthcare team should be aware of such trade-offs when they make decisions about rehabilitation services.

Inter- and intra-interviewer reliability of Italian version of Pediatric Evaluation of Disability Inventory (I-PEDI).

BACKGROUND: Childhood disabilities determine a range of immediate and long-term economic costs that have important implications for the well-being of the child, the family and the society. The Pediatric Evaluation of Disability Inventory (PEDI) measures capability and performance in children aged between 6 months and 7.5 years. It contains three scales: Functional Skills Scales (FSS), Caregiver Assistance Scale (CAS) and Modifications Scale (MS). The present study evaluated the measurement properties of the Italian version of the PEDI (PEDI-I) in patients with spastic cerebral palsy (CP). STUDY DESIGN: Reliability study. METHODS: The original PEDI was translated - including a cross-cultural adaptation - into Italian. Internal consistency and test-retest reliability were evaluated. RESULTS: Fifty-eight children with CP were recruited. According to inter-interviewer reproducibility, the FSS domain revealed intraclass correlation coefficient (ICC) values ranging between 0.94 and 1.00. CAS domain revealed ICC values ranging between 0.94 and 1.00. The SEM values ranged between 3.25 (SDD=8.98) for SF and 5.24 for SC (SDD=14.5). According to intra-interviewer reproducibility, the FSS domain revealed ICC values ranging between 0.99 and 1.00. CAS domain revealed ICC values ranging between 0.92 and 0.99. The SEM values ranged between 3.44 (SDD=9.5) for SF and 3.75 for SC (SDD=10.36). The inter-interviewer and intra-interviewer reproducibility results showed very high ICC values for both FFS and CAS domains. Cronbach's α ranged between 0.94 and 0.99, indicating excellent internal consistency within each domain of the PEDI-I. CONCLUSION: The inter-interviewer and intra-interviewer reproducibility results of PEDI-I showed very high ICC values for FFS and CAS domains. Therefore, we recommend its application to evaluate the effect of treatment in children with CP.

Efficacy of ultrasound therapy combined with cryotherapy in pain management and rehabilitation in patients with Achilles tendinopathy: a retrospective observational study.

Background: Achilles tendinopathy (AT) is characterized by pain, reduced performance, and swelling in and around the tendon. The aim of our study was to evaluate and compare the effects of ultrasound therapy alone or associated with cryotherapy. Methods: We analyzed retrospectively amateur runner patients who run at least 3 times a week, with medical and ultrasound diagnosis of subacute AT of the midportion. All patients underwent 10 sessions of ultrasounds' therapy with qmd® ultrasound cryo and a therapeutic exercise with stretching and eccentric exercises. The Cryo-Ultrasound Group (CUG, 15, 8M and7/F), during the ultrasound treatment, underwent a session of cryo-ultrasound therapy. The Ultrasound Group (UD, 15, 7M and 8F) only performed ultrasound therapy. Results: All evaluations performed show significant improvement over time in both groups. The CUG shows at T1 a greater increase in pain and function compared to the UG. Friedmann's repeated measures analysis shows that both groups improved when assessed separately over time. From the subsequent post hoc analysis, a statistically significant difference is highlighted between the values evaluated at T0 and T3. Conclusions: The possible simultaneous delivery of the two treatment modalities, in patients suffering from tendinopathies, therefore represents a good possibility of synergistically exploiting their therapeutic actions. Future studies with a larger patient sample and longer follow-up are also needed to better evaluate the benefits of this treatment.

Gait analysis advancements: rehabilitation value and new perspectives from forensic application.

The clinical and rehabilitation value of gait analysis is remarkable and indisputable and poised to grow as technological advancements unfold. This article aims to shed light on the advances in how gait is assessed, enabling those who have suffered an injury impairing their motor skills to be diagnosed more accurately and efficiently as well as to compare the hallmarks of rehabilitative and forensic gait analysis. The authors have conducted an analysis of relevant papers (published between 1967 and 2020) from a medicolegal perspective, cited in PubMed, MEDLINE, Cochrane Library, EMBASE, and available recommendations for the legal application of such techniques. Moreover, considering the use of gait analysis as a forensic tool, this study broadens the scope of research by including search engines, legal databases, and court filings (DeJure, Lexis Nexis, Justia) between 2000 and 2022. The instrumental assessment of movement (Gait Analysis) has come to constitute an essential analytical tool for the biomedical sector to objectively and accurately assess human movement and posture. The article is also aimed at elaborating differences and similarities between clinical and forensic gait analysis. When it comes to the forensic applicability of gait analysis and its evidentiary value, however, there is a pressing need for a review of its scientific basis. Therefore, it is necessary to conduct a thorough evaluation of its use in legal practice, as stressed in scientific literature and surveys. It is of utmost importance to highlight the procedural and assessment standards currently applied to forensic gait analysis, to evaluate its strengths and weaknesses, and to achieve standardized guidelines based on broad scientific consensus.

Effectiveness of Kinesiotaping and McConnell taping combined with physical exercise on gait biomechanics in patients with patellofemoral syndrome: non-randomized clinical trial.

Background: Patellofemoral pain syndrome (PFPS) is a pathological condition of the knee, typical of young adults, characterized by diffuse pain in the anterior and / or medial part of the knee. We aimed to examine the effectiveness of the two types of taping in association with therapeutic exercise in relation to the biomechanical parameters, on pain and on functionality of the lower limb in patients with PFPS. Methods: We collected data from patients treated in our outpatient's clinic with two kinds of bandage: the Kinesiotaping group (KG) and the McConnel taping group (MG). All subjects were evaluated trough an optoelectronic system, the Numeric Pain Rating Scale (NPRS), and with the Lower Extremity Functional Scale (LEFS) at baseline before applying the taping (T0), fifteen minutes after applying the bandage (T1), after four weeks of treatment (T2) without applying the bandage and three months after the end of the first treatment period with bandages and exercises (T3). Results: Thirty-five patients (KG 16; MG 19) were included in the study. The most statistically significant changes over time in the LEFS and NPRS values have been recorded in the MG group compared to KG. The average speed and hip rotation showed a statistically significant increase between T3 and T0. Conclusion: The application of the knee bandage for PFPS would appear to show improvement in NPRS and LEFS outcomes in both groups. Furthermore, in this study the MG evidenced better results and significant changes over time than KG.

Natural history of ileo-caecal Crohn's disease after surgical resection. A long term study.

AIM: Surgery is an almost inevitable event in Crohn's disease (CD) but is not curative; postoperative recurrence follows a predictable course. Several factors potentially affecting the risk of recurrence have been investigated but results are largely inconclusive. The aim of the present study was to evaluate the long-term course of ileo-caecal CD after surgery and to identify possible predictors of clinical and surgical recurrence. METHODS: Patients with ileo-caecal CD who had undergone surgical resection and with at least one year of post-operative follow-up were studied. The postoperative course was retrospectively evaluated. The primary end-points were clinical recurrence (defined as reappearance of symptoms requiring steroid treatment in the presence of endoscopic and/or radiologic recurrence) and surgical recurrence, defined as need for reoperation. RESULTS: Two hundred and twelve patients were included in the study. Median follow-up after surgery was 117 months (interquartile range 51-216). The cumulative probability of a post-operative course without clinical and surgical recurrence after 30, 60, 90, 120 months was 78.2%, 69.4%, 58.0%, 50.6% and 97.0%, 96.4%, 85.6%, 72% respectively. Early surgery (within three years from diagnosis) was associated with a longer postoperative course without clinical recurrence compared with late surgery (performed after three years from diagnosis). None of the other clinical variables considered (gender, age, family history for IBD, smoking habits, pattern of CD, and postoperative prophylactic treatment) was associated with the risk of clinical and surgical recurrence. CONCLUSION: Surgery is an excellent treatment for patients with isolated ileo-caecal CD. The overall long-term outcome is good: by 10 years after operation approximately 50% of patients are free of clinical recurrence and over 70% do not require further surgery. Surgery, therefore, continues to play an important role in ileo-caecal CD and should therefore not be considered only a failure of medical treatment.

Evidence of Rehabilitative Impact of Progressive Resistance Training (PRT) Programs in Parkinson Disease: An Umbrella Review.

Parkinson disease (PD) is a chronic neurodegenerative condition that leads to progressive disability. PD-related reductions in muscle strength have been reported to be associated with lower functional performance and balance confidence with an increased risk of falls. Progressive resistance training (PRT) improves strength, balance, and functional abilities. This umbrella review examines the efficacy of PRT regarding muscular strength in PD patients. The PubMed, PEDro, Scopus, and Cochrane Library databases were searched from January 2009 to August 2019 for systematic reviews and meta-analyses conducted in English. The populations included had diagnoses of PD and consisted of males and females aged >18 years old. Outcomes measured were muscle strength and enhanced physical function. Eight papers (six systematic reviews and meta-analyses and two systematic reviews) were considered relevant for qualitative analysis. In six of the eight studies, the reported severity of PD was mild to moderate. Each study analyzed how PRT elicited positive effects on muscle strength in PD patients, suggesting 10 weeks on average of progressive resistance exercises for the upper and lower limbs two to three times per week. However, none of the studies considered the postworkout follow-up, and there was no detailed evidence about the value of PRT in preventing falls. The possibility of PRT exercises being effective for increasing muscle strength in patients with PD, but without comorbidities or severe disability, is discussed. Overall, this review suggests that PRT should be included in rehabilitation programs for PD patients, in combination with balance training for postural control and other types of exercise, in order to preserve cardiorespiratory fitness and improve endurance in daily life activities.

An update on AIDS-related cholangiopathy.

Both hepatic parenchymal and biliary tract diseases are common in patients with human immunodeficiency virus (HIV). In this paper, the authors focus mainly on clinical aspects of acquired immunodeficiency syndrome (AIDS)-related cholangiopathy. Although the etiology is unclear, several opportunistic infections (cytomegalovirus, Cryptosporidium and others) are suspected to cause it. Endoscopic retrograde cholangiopancreatography (ERCP) is the diagnostic gold standard and it offers a therapeutic means to provide symptomatic relief in case of papillary stenosis. The most common ERCP pattern is diffuse sclerosing cholangitis in combination with papillary stenosis. Clinically, the presentation may be variable, although right upper quadrant pain and fever accompanied by an elevated serum alkaline phosphatase (ALP) level are the most common manifestations. Jaundice is unusual suggesting that complete ductal obstruction is rare. While ERCP results and the need of sphincterotomy do not influence the prognosis, antiretroviral therapy is a protective factor and, on the contrary, high ALP level is related to a less favorable outcome. Regarding the possible pathogenic mechanisms through which HIV infection could be involved in AIDS-related cholangiopathy, in vitro experiments have shown that concurrent active HIV replication and Cryptosporidium parvum infection synergistically increase cholangiocyte apoptosis and thus jointly contribute to AIDS-related cholangiopathies.

RNAi analysis of genes expressed in the ovary of Caenorhabditis elegans.

As a step towards comprehensive functional analysis of genomes, systematic gene knockout projects have been initiated in several organisms [1]. In metazoans like C. elegans, however, maternal contribution can mask the effects of gene knockouts on embryogenesis. RNA interference (RNAi) provides an alternative rapid approach to obtain loss-of-function information that can also reveal embryonic roles for the genes targeted [2,3]. We have used RNAi to analyze a random set of ovarian transcripts and have identified 81 genes with essential roles in embryogenesis. Surprisingly, none of them maps on the X chromosome. Of these 81 genes, 68 showed defects before the eight-cell stage and could be grouped into ten phenotypic classes. To archive and distribute these data we have developed a database system directly linked to the C. elegans database (Wormbase). We conclude that screening cDNA libraries by RNAi is an efficient way of obtaining in vivo function for a large group of genes. Furthermore, this approach is directly applicable to other organisms sensitive to RNAi and whose genomes have not yet been sequenced.

Rhabdomyolysis due to severe hypokaliemia in a Crohn's disease patient after budesonide treatment.

Patients with Crohn's disease may experience several non-digestive complications, including muscle disorders. Rabdomyolysis has rarely been reported in patients with inflammatory bowel disease, however a number of factors may cause muscular damage in this setting. We report the case of a young woman with Crohn's disease who developed a severe, symptomatic skeletal muscle damage associated with severe hypokaliemia. Reversal of the potassium levels to normal ranges led to clinical resolution. The possible causes that might have lead to hypokalemia development and subsequent rhabdomyolysis are discussed with special emphasis for the potential causative role of medical treatment, especially budesonide for which similar side effects have been previously reported. Physicians should be aware that hypokalemia is possible in the setting of Crohn's disease and muscle damage can present as a complication.

Extracorporeal shock wave therapy and ultrasound therapy improve pain and function in patients with carpal tunnel syndrome. A randomized controlled trial.

BACKGROUND: Ultrasound (US) therapy improves symptoms in carpal tunnel syndrome (CTS) patients. Extracorporeal shock wave therapy (ESWT) uses acoustic energy to determine its clinical effects, as US-therapy does. AIM: The aim of this study was to compare the short-term efficacy of US and ESWT on mild and moderate CTS. STUDY DESIGN: Randomized controlled trial. SETTING: University outpatient service. POPULATION: Twenty-five patients with mild to moderate CTS, for a total of 42 wrists. METHODS: patients were randomized to receive US, cryo-US or ESWT, and were evaluated for pain and function before treatment started, at the end of treatment, and four and 12 weeks after the end of the treatment. RESULTS: Significant improvement was noted in all groups for pain (P<0.05) and functionality (P<0.05). Patients in ESWT group show greater pain improvement at 12-weeks follow-up when compared with both US and cryo-US groups (P<0.05). CONCLUSION: Patients affected by CTS might benefit from the application of US, cryo-US or ESWT. Benefits persist 3 months after the end of treatment. CLINICAL REHABIL IMPACT: Clinicians might consider the possibility of a short-term non-surgical management for mild-to-moderate CTS.

Unilateral deep brain stimulation of the pedunculopontine tegmental nucleus in idiopathic Parkinson's disease: effects on gait initiation and performance.

The pedunculopontine tegmental nucleus (PPTg) is a component of the locomotor mesencephalic area. In recent years it has been considered a new surgical site for deep brain stimulation (DBS) in movement disorders. Here, using objective kinematic and spatio-temporal gait analysis, we report the impact of low frequency (40 Hz) unilateral PPTg DBS in ten patients suffering from idiopathic Parkinson's disease with drug-resistant gait and axial disabilities. Patients were studied for gait initiation (GI) and steady-state level walking (LW) under residual drug therapy. In the LW study, a straight walking task was employed. Patients were compared with healthy age-matched controls. The analysis revealed that GI, cadence, stride length and left pelvic tilt range of motion (ROM) improved under stimulation. The duration of the S1 and S2 sub-phases of the anticipatory postural adjustment phase of GI was not affected by stimulation, however a significant improvement was observed in the S1 sub-phase in both the backward shift of centre of pressure and peak velocity. Speed during the swing phase, step width, stance duration, right pelvic tilt ROM phase, right and left hip flexion-extension ROM, and right and left knee ROM were not modified. Overall, the results show that unilateral PPTg DBS may affect GI and specific spatio-temporal and kinematic parameters during unconstrained walking on a straight trajectory, thus providing further support to the importance of the PPTg in the modulation of gait in neurodegenerative disorders.

[Role of rifaximin in the treatment of colonic diverticular disease]. / Ruolo della rifaximina nel trattamento della malattia diverticolare del colon.

Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect healthcare costs in western countries. Although most patients with colonic diverticula remain asymptomatic for their whole life, in 20-25% of cases will develop symptoms. Antibiotics are commonly used in the treatment of inflammatory complication of diverticular disease. Several clinical observation suggest a role of rifaximin in the management of symptomatic uncomplicated diverticular disease of the colon. This is a critical review of clinical studies addressing the role of long term administration of rifaximin for the treatment of symptomatic colonic diverticular disease. The evidence from prospective controlled trials suggests that rifaximin is effective for obtaining symptomatic relief in patients with uncomplicated diverticular disease. The therapeutic gain compared with fiber supplementation only is approximately 30%. No definitive conclusion can be drawn regard a possible role of rifaximin for preventing diverticulitis.
