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.

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

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.

PTH-rP and PTH-R1 Expression in Placentas from Pregnancies Complicated by Gestational Diabetes: New Insights into the Pathophysiology of Hyperglycemia in Pregnancy

Background: this study investigated the expression of parathyroid hormone-related protein (PTH-rP) and PTH/PTH-rP receptor PTH-R1 in placentas from women with gestational DM (GDM), and the relationship between PTH-R1 and PTH-rP expression and pregnancy characteristics. Methods: we prospectively enrolled 78 pregnant women with GDM, and immunochemistry for PTH-rP and PTH-R1 was performed on placentas. Patients were grouped according to the positivity of PTH-R1 or PTH-rP expression, and pregnancy characteristics were compared between the two groups. Results: PTH-rP and PTH-R1 expression were highest in the extravillous cytotrophoblast and in the decidua. In extravillous cytotrophoblast, PTH-rP expression was higher in women with abnormal at fasting glycemia compared to women with abnormal 60′ or 120′ glycemia (25/25, 50% vs. 6/28, 21.4%, χ2 = 6.12, p = 0.01), and PTH-R1 expression was higher in women with abnormal oral glucose tolerance test (OGTT) at fasting glycemia compared to women with abnormal 60′ or 120′ glycemia (37/50, 74% vs. 15/28, 53.6%, χ2 = 3.37, p = 0.06). In syncytiotrophoblast, PTH-rP-positive placentas were characterized by higher incidence of 1 min Apgar score < 7 (2/9, 22.2% vs. 2/69, 2.9%, χ2 = 6.11, p = 0.01) and maternal obesity (4/9, 44.4% vs. 11/69, 16.7%, χ2 = 3.81, p = 0.05). Conclusion: placental PTH-rP and PTH-R1 expression is dependent on the type of maternal hyperglycemia, and it is associated with adverse pregnancy outcomes.

A case of fatal embolization during laser lithotripsy

PURPOSE

To report in literature the first case of fatal multi-organ embolization of ureteral stones fragments during laser lithotripsy.

CASE PRESENTATION

A tetraplegic 43-year-old woman was admitted to the hospital to undergo laser lithotripsy because of bilateral ureteral stones and right ureteral infected stent. During the removal of the right ureteral stent, the patient developed a sudden severe bradycardia followed by a reduction in the arterial oxygen saturation. In spite of a rapid and intensive medical intervention, the clinical picture did not improve; the woman was therefore transferred to the nearest Emergency Room where she was rescued but a cardiocirculatory arrest occurred. A claim of alleged medical malpractice was brought against the urologists. A complete autopsy was performed 8 days after death.

AUTOPSY FINDINGS

The diagnosis was determined by the microscopic findings: they have unequivocally shown a massive embolization of calculus fragments in the lungs and in the heart. In the light of all these findings, the cause of death was attributable to a disseminated intravascular coagulation due to this unforeseeable embolization of calcified amorphous material.

CONCLUSION

Embolization of calculus fragments represents an important challenge because it is extremely unpredictable. Indeed, a prompt diagnosis of non-thrombotic pulmonary embolism, during the urologic procedure, is extremely difficult because the condition presents with no specific clinical signs: this life-threatening pathology is often underestimated. For this reason, the autopsy and the subsequent histopathological examination are indispensable in order to prove lethal embolization: microscopic findings play a key role in the final diagnosis of death.

Right sinus of Valsalva aneurysm

Aneurysms in the sinuses of Valsalva (SVA) are the least frequent and occur due to a weakness in the aortic wall that forms part of the sinus. This causes dilatation and the formation of a blind pocket in one of the aortic sinuses (usually he right sinus and less frequently the posterior one). It may be congenital or acquired: in a congenital SVA, the condition is frequently associated with Marfan's syndrome or other connective tissue disorders; instead, acquired forms of sinus of Valsalva aneurysm are associated with infections (syphilis, bacterial endocarditis, and tuberculosis), atherosclerosis and medial cystic necrosis, traumatic and degenerative diseases, abuse of drugs or alcoholism. Despite SVA is a well-known anomaly, autopsy images or reviews of the condition are very uncommon. Indeed we report here a fatal case of SVA in a 58-year-old homeless man found dead on the street. The autopsy, performed to determine the cause of death, releaved a massive aneurysm (in excess of 4 cm) involving the right coronary sinus of the aorta. In this case, the aneurysm may be an accidental finding: in effect we found no tromboses inside the aneurysm and the ostium was not obstructed, therefore the cause of death could be attribuited to fatal arrhythmia.

Extracorporeal shockwave therapy on muscle tissue: the effects on healthy athletes

The aim of this study is to investigate the effects of extracorporeal shock wave therapy (ESWT) on muscle rheological and functional properties in a population of young athletes. Thirty-two football and basketball players were recruited and randomized into two groups. The athletes underwent three sessions of therapy administered every five days to the thigh muscles. The treatment consisted of ESWT (electromagnetic generator, Energy Flux Density=0.03 mJ/mm2) or a placebo treatment bilaterally on the quadricep and femoral bicep muscles. Monitoring was carried out at recruitment (T0), at the end of treatment (15 days, T1) and at 30 days (T2) with myometric evaluation (measuring elasticity, stiffness and muscular tone) and electromiography exam (recording the Motor Unit Amplitude Potential values). The results showed a significant increase in the treated athletes in the elasticity (lateral vastus muscle, p=0.007), in muscular tone (femoral rectus, p=0.031) and in muscular recruitment (the lateral vastus, p<0.005; medial vastus muscle, p=0.055). These results could represent a translational interpretation of the known biological effect on connective tissue: an increase in blood flow, oxygenation, metabolic process activation and proliferative effect. The effects found may represent the justification for verifying the usefulness of using of shockwave therapy to reduce muscular fatigue and improve performance during the sport season.
