Case Report: Rehabilitation for Lower Extremity Pain Due to Venous Stasis in a Patient With Multisystem Inflammatory Syndrome in Children

Recently, it was reported that children recovering from coronavirus disease (COVID-19) developed multisystem inflammatory syndrome in children (MIS-C), which causes severe inflammation in multiple organs of the body. Because MIS-C is a new disease, the pathophysiology and prognosis are unknown. Owing to a lack of studies on this subject, we herein provide information on rehabilitation for children with MIS-C. A 12-year-old male patient presented with systemic inflammatory symptoms after approximately 2 months since recovery from COVID-19. He was treated with cyclosporine and steroid pulse therapy after admission to our hospital. His general condition improved significantly within approximately 1 week. Thereafter, his lower legs turned dark purple and he experienced intense pain whenever the lower limbs hung below the heart, such as in the sitting position. The patient was referred to the rehabilitation department, as he had difficulties during standing and walking. Because the symptoms improved with elevation of the lower extremities, we considered that the pain was related to venous stasis. The pain reduced when an elastic bandage was applied for the prevention of venous stasis; therefore, exercise therapy was implemented while the patient wore the elastic bandage. The patient's lower extremity symptoms improved in 10 days. He was discharged after 16 days and could independently perform activities of daily living (ADL). The mechanism underlying the patient's pain could not be determined; however, rehabilitation was effective when combined with compression therapy using an elastic bandage.

Hirayama disease. Clinical cases

Hirayama disease, or monomelic amyotrophy, is a rare neurological pathology manifested by unilateral or bilateral asymmetric paresis with atrophy of the distal upper extremities. The development of this disease is associated with the forward displacement of the posterior dural sac during neck flexion, which leads to compression of the spinal cord and venous stasis. The diagnosis of monomelic amyotrophy is based on the clinical picture and the results of magnetic resonance imaging of the cervical spine with flexion, showing segmental atrophy of the anterior horns of the spinal cord at C7 — Th1, detachment of the posterior dura mater and venous stasis. Most of the cases described in the literature are from India and Japan, with isolated cases diagnosed in North America and Europe. This article presents two clinical cases of progressive hand weakness in young men. The clinical picture of the disease and the results of additional examination methods are presented, which is necessary to establish a diagnosis of Hirayama’s disease.

Chronic venous insufficiency after COVID-19: management of edema and pain syndromes

Introduction. COVID-19 infection raises many questions regarding the health condition of patients after they have had COVID-19. The aim of this study is to examine the characteristic symptoms of chronic venous insufficiency in the postcovid period.Materials and methods. The materials that were used for work included the results of studying the medical aid appealability, characteristic symptoms, diagnosis and treatment of symptoms of chronic venous insufficiency in persons who have had the coronavirus infection. 47 patients presented with complaints about deterioration of their condition after they had had COVID-19 over March to September 2021 period. Methods: general clinical examiniation, ultrasound angioscanning of veins of the lower extremities, laboratory coagulation tests.Results and discussion. Before deterioration, calf circumference was measured 22–24 cm at a typical measurement site in most patients (89%), after covid infection it reached 26–27 cm. Varicose veins remained soft, without intravascular formations, edema was often bilateral, asymmetric, pain was described as constant (5–6 VAS scores), patients had prominent signs of lymphostasis. 35 out of 47 people received diosmin-based venotonic drug of Russian manufacture at a dose of 1000 mg/day (one tablet twice a day), the course of treatment lasted one to two months. After that period, the edema subsided in 85% of patients, the severity of pain syndrome significantly reduced (up to 2–3 VAS scores). With regard to chronic venous insufficiency in patients with chronic diseases of lower extremity veins (mostly varicose and post-thrombotic diseases), the significant progress of disease was observed in almost 94% of follow-up cases. Diosmin is the main drug that is prescribed to treat chronic venous insufficiency. The drug has an angioprotective and venotonic effect, reduces the vein wall elasticity, increases venous tone, and decreases venous stasis, reduces capillary permeability and fragility, and increases their resistance, improves microcirculation and lymphatic drainage.Сonclusions. In the postcovid period, clinical symptoms of some chronic diseases occur/worsen, including clinical manifestations of chronic venous insufficiency. The use of Russian diosmin-based drug for the management of edema and pain syndrome is very promising.

Retinal Vascular Events after mRNA and Adenoviral-Vectored COVID-19 Vaccines—A Case Series

Background: To describe cases of retinal vascular events shortly after administration of mRNA or adenoviral-vectored COVID-19 vaccines. Design: Retrospective, multicenter case series. Methods: Six cases of retinal vascular events shortly after receiving COVID-19 vaccines. Results: A 38-year-old, otherwise healthy male patient presented with branch retinal arterial occlusion four days after receiving his second dose of SARS-CoV-2 vaccination with Comirnaty® (BioNTech®, Mainz, Germany; Pfizer®, New York City, NY, USA). An 81-year-old female patient developed visual symptoms twelve days after the second dose of SARS-CoV-2 vaccination with Comirnaty® and was diagnosed with a combined arterial and venous occlusion in her right eye. A 40-year-old male patient noticed blurry vision five days after his first dose of SARS-CoV-2 vaccination with Comirnaty® and was diagnosed with venous stasis retinopathy in his left eye. A 67-year-old male was diagnosed with non-arteritic anterior ischemic optic neuropathy in his right eye four days after receiving the first dose of Vaxzevria® (AstraZeneca®, Cambridge, UK). A 32-year-old man presented with a sudden onset of a scotoma two days after receiving the second dose of SARS-CoV-2 vaccination with Spikevax® (Moderna, Cambridge, UK) and was diagnosed with a circumscribed nerve fiber infarction. A 21-year-old female patient developed an acute bilateral acute macular neuroretinopathy three days after receiving the first dose of SARS-CoV2-vaccine Vaxzevria® (AstraZeneca®, Cambridge, UK). Conclusion: This case series describes six cases of retinal vascular events shortly after receiving mRNA or adenoviral-vectored COVID-19 vaccines. The short time span between received vaccination and occurrence of the observed retinal vascular events raises the question of a direct correlation. Our case series adds to further reports of possible side effects with potential serious post-immunization complications of COVID-19 vaccinations.

Congenital Anomalous Azygos Vein Drainage Causing Pulmonary Embolus in a 91-Year-Old Patient

Background: Retroaortic course and azygos continuation of aberrant left brachiocephalic vein is a rare venous anomaly, which is usually associated with congenital heart disease and pulmonary artery anomalies. Venous stasis is a cause of pulmonary arterial thromboembolism, which can result from venous anomalies. Case presentation: We describe the case of a 91-year-old female admitted to our hospital with shortness of breath diagnosed with pulmonary embolism and infarctions by a CT pulmonary angiogram. CT also showed aberrant left brachiocephalic vein with vascular webs at its retroaortic course and azygos continuation, suggesting chronic venous thrombosis, which was considered to be the suspected source of emboli. Conclusion: To our knowledge, this is the first report presenting this vascular anomaly manifesting with chronic venous thrombosis and pulmonary embolism. Although rare, awareness and identification of this entity is important, especially in the absence of obvious embolic sources or in patients with recurrent embolus/consolidation.

The Prevalence of May Thurner Syndrome in Children with Ileo-Femoral Deep Vein Thrombosis- Does It Take 2 to Tango?

Introduction: May-Thurner syndrome (MTS) is characterised by compression of the left external iliac vein by overriding right common iliac artery resulting in venous stasis. It carries a higher risk of left iliofemoral deep vein thrombosis (DVT), however the prevalence and management guidelines are unclear in pediatrics. We reviewed the prevalence of MTS in children diagnosed with left iliofemoral DVT at our center, associated prothrombotic risk factors and their clinical outcomes. Methods: This is a retrospective audit of pediatric patients (<18 years) with left iliofemoral DVT treated at the IWK Health Center from January 1 2008 to December 31 2020. Results: Twelve pediatric patients with left iliofemoral DVT were identified at our center and all patients except one had MRV/CTV during their course of anticoagulation to evaluate for MTS. MTS was diagnosed on imaging in 8 of the eleven evaluable patients with DVT and one patient had an incidental diagnosis of MTS with no DVT. The median age at diagnosis of MTS was 15 years (13-16), male:female ratio of 1:8. The overall prevalence rate was of MTS was 72.72% (8/11) in patients with left iliofemoral DVT. All patients with iliofemoral DVT and MTS had at least one other prothrombotic risk factor- initiation of estrogen containing contraceptive pills in the preceding 3 months of the DVT (n=5), inherited thrombophilia (n=2) and obesity (n=2). All patients with MTS were referred to vascular surgery. Only one patient required catheter directed thrombolysis and stenting at presentation of DVT, the remaining 7 patients were managed with anticoagulation alone. Complete (n=1) or partial (n=7) resolution of the thrombus was seen in all 8 patients. Median duration of follow up was 3 years. Recurrent DVT was seen in 1 patient and two patients came off anticoagulation at 6 months post therapy. Post thrombotic syndrome was seen in 4 patients, mild in 3 and moderate in 1; as per modified Villalta score. Conclusion: We observed a high prevalence of MTS in patients with left iliofemoral DVT which may be due our screening approachwith upfront radiographic evaluation for MTS in all patients with left iliofemoral DVT. A second pro-thrombotic risk factor was identified in all patients, which raises the possibility of a "two hit theory" for the occurrence of DVT in MTS. Compared to published adult studies, majority of our pediatric patients were managed conservatively with anticoagulation therapy alone. Disclosures No relevant conflicts of interest to declare.

Exercise Plan in Preventing of Pressure Ulcers among Post Operative Patients

Background: Pressure ulcers are the common conditions among patients hospitalized in acute and chronic care facilities and impose significant burden on patients, their relatives and caregivers. Pressure ulcers have been described as one of the most costly and physically debilitating complications since the 20th century. The pain and discomfort due to pressure ulcer prolongs illness, rehabilitation, time of discharge and even contribute to disability and death. Lengthy periods of immobilization are emotionally stressful for patients. Immobility related problems include pressure ulcers, pneumonia, constipation, loss of appetite, urinary stasis, urinary track infections and venous stasis or deep vein thrombosis. When the complications due to immobilization are prevented it helps an individual to be physically, emotionally and psychologically sound. These complications can be prevented through simple basic patient care like skincare, active-passive exercises, changing position and deep breathing exercises. Nurses have a key role in prevention of these complications by educating the patients. Hence the study was conducted “To evaluate the effectiveness of structured teaching programme regarding prevention of complications of immobilized patients . methods: The study involved 50 immobilized orthopaedic patients using the structured interview schedule. STP was implemented and post-test was conducted after 8 days using the same structured interview schedule to find out the effectiveness. Results: 86% of respondents were taking mixed diet and 60% had compound fracture. The main cause for the fracture was road traffic accident (46 %). Regarding effectiveness of Structure exercise plan , the overall mean percentage knowledge score in the pre-test was 34.71% and 80.91% in the post-test. The statistical paired ‘t’ test indicates that enhancement in the mean percentage knowledge score was found to be significant at P≤0.05 percent level for all the aspects . Conclusion: This study revealed that nursing staffs’ knowledge and practice about pressure ulcer preventive measures could be improved. Participants in the study reported that they could use the educational program effectively and easily in the prevention of pressure ulcers among their immobilized patients, which decreases the occurrence of pressure ulcers and as well as improved patient outcome.

Pathogenesis of Autoimmune Male Infertility: Juxtacrine, Paracrine, and Endocrine Dysregulation

According to global data, there is a male reproductive potential decrease. Pathogenesis of male infertility is often associated with autoimmunity towards sperm antigens essential for fertilization. Antisperm autoantibodies (ASAs) have immobilizing and cytotoxic properties, impairing spermatogenesis, causing sperm agglutination, altering spermatozoa motility and acrosomal reaction, and thus preventing ovum fertilization. Infertility diagnosis requires a mandatory check for the ASAs. The concept of the blood–testis barrier is currently re-formulated, with an emphasis on informational paracrine and juxtacrine effects, rather than simple anatomical separation. The etiology of male infertility includes both autoimmune and non-autoimmune diseases but equally develops through autoimmune links of pathogenesis. Varicocele commonly leads to infertility due to testicular ischemic damage, venous stasis, local hyperthermia, and hypoandrogenism. However, varicocelectomy can alter the blood–testis barrier, facilitating ASAs production as well. There are contradictory data on the role of ASAs in the pathogenesis of varicocele-related infertility. Infection and inflammation both promote ASAs production due to “danger concept” mechanisms and because of antigen mimicry. Systemic pro-autoimmune influences like hyperprolactinemia, hypoandrogenism, and hypothyroidism also facilitate ASAs production. The diagnostic value of various ASAs has not yet been clearly attributed, and their cut-levels have not been determined in sera nor in ejaculate. The assessment of the autoimmunity role in the pathogenesis of male infertility is ambiguous, so the purpose of this review is to show the effects of ASAs on the pathogenesis of male infertility.
