Some studies propose direct endothelial injury by the COVID virus, causing microvascular inflammation, endothelial exocytosis, and endothelitis. Erythrocytosis can be categorized as primary, secondary, or relative. Gregory J. During this time, he had no chest pain, palpitations, shortness of breath, or abnormal cardiopulmonary exam. Segmental zoster paresis should be suspected in any patient with paralysis and recent diagnosis of shingles.

Atherosclerosis is the leading cause of Cardiovascular Disease, which is still the global leader of mortality. Results of our previous in vitro experiments suggest that macrophages play a predominant role in mediating IGF1 effects in atherosclerotic plaque, but exact mechanisms remain unclear. We hypothesized that increasing IGF1 levels strictly in macrophages will prevent atherosclerosis. We accelerated atherosclerotic development by feeding animal a high fat diet for three months.
We also assessed cholesterol efflux and foam cell formation in vivo and in vitro. Our results indicate that macrophage IGF1 reduces atherosclerosis and decreases CXCL12, a chemokine newly implicated in atheroprogression. IGF1 potentially exerts its atheroprotective effect via this reduction in CXCL12 by reducing monocyte recruitment and by increasing ABCA1, thereby increasing cholesterol efflux capacity.
Estimation of the effect of this amyloidogenic TTR variant on the risk of heart failure HF and all-cause mortality in a large, geographically diverse cohort of Black Americans may provide insight into the clinical significance of this variant. Poisson regression was used to estimate the rates of incident HF and all-cause mortality.
We used multivariable-adjusted Cox regression models accounting for demographic, clinical, and social factors, and genetic African ancestry to assess the risk of incident HF and all-cause mortality among those carrying TTR ValIle genetic variation compared with those without the variation. The incidence of HF per person-years was The incidence of all-cause mortality per person-years was ValIle variant carrier had a higher risk of all-cause mortality HR: 1.
There was no interaction between TTR variant carrier status and sex on HF and all-cause mortality outcome. With the advent of numerous hATTR therapies, the presence of TTR ValIle mutation seen commonly in those with African ancestry may be deemed clinically actionable and prompt an early access to therapy.
The objective of present study was to examine the effect of Vitamin D vitD in the regulation of Npr1 gene transcription and expression via modulation of epigenetic factors. Our bioinformatics study with the murine Npr1 promoter has shown presence of 4 vitD response elements VDRE in the region to from the transcription start site having perfect and VDRE-like consensus sequence.
To delineate the mechanisms of the regulation of the promoter activity of Npr1 promoter deletion constructs were transiently transfected in cultured rat thoracic aortic smooth muscle cells RTASMCs and mouse mesangial cells MMCs and the transcriptional activity was measured dual luciferase assay kit. Western blot and densitometry analysis showed increasing concentrations of VD3 significantly induced NPRA protein levels by 3.
The results demonstrate that VD3 regulate Npr1 gene expression epigenetically by modulation of histone modifications. The identification of epigenetic targets of vitamin D signaling as a regulator of Npr1 gene transcription and protein expression will have important implications in hypertension and cardiovascular regulation. Show that entanglement and superconductivity improves intracellular conduction in paired isolated heart myocites, improving coupling and left ventricular function.
Using the quantum concepts of entanglement and superconductivity experiments were done, intracellularly, using artificial intelligence; measuring intracellular electrical conduction across junction gaps G.
Ang II. We think the plateau was reached after a reduction of entanglement, but not with Ang II. In a superconductivity state, E.
Further studies are needed to fully understand the hemodynamics changes done in a quantum state. Coronavirus disease COVID can range from asymptomatic infection to severe illness with multiorgan failure. But the results lack consistency, and the magnitude of the association is currently unknown.
We included articles from PubMed and Embase up to September 1, Among the articles retrieved, 29 articles 26 retrospective and 3 prospective cohorts met the inclusion criteria with an aggregate of , participants.
None of the above analyses showed statistically significant publication bias. We believe that reduced lipoprotein levels are secondary to systemic inflammation and hepatic dysfunction.
Atrial and brain natriuretic peptides ANP and BNP are circulating hormones of cardiac origin that play pivotal roles in regulating blood pressure and fluid homeostasis through vasodilatory and diuretic actions and improve cardiac remodeling.
However, the underlying mechanisms are not yet precisely determined. The aim of this study was to investigate whether Npr1 plays a critical role in regulating glucose homeostasis in Npr1 gene-disrupted mice. Systolic blood pressure SBP was determined by non-invasive computerized tail-cuff method Visitech The present findings showed that Npr1 markedly prevented a steep rise of blood glucose levels after glucose challenge and ameliorated glucose intolerance in wild-type and gene-duplicated mice, suggesting that Npr1 plays a critical role in the regulation of glucose levels and the loss of Npr1 exerts detrimental effects on renal and cardiac functions in mutant mice.
Agreement between randomized and observational studies is uncertain. Meta-analysis with subgroup comparison was completed with calculation of odds ratios for death with invasive therapy vs death with conservative therapy. The odds ratio for death with invasive therapy in the observational studies with eGFR 30—60 was 0. Despite the technical advances in cardiology, cardiogenic shock as a complication of acute myocardial infarction remains a medical challenge.
Recently there has been a movement to standardize cardiogenic shock management across the United States with the National Cardiogenic Shock Initiative aiming to improve survival, particularly in acute coronary syndrome patients ACS. We aim to determine how cardiogenic shock secondary to ACS that required mechanical circulatory support is managed in our institution and compare the clinical characteristics between survivors and non-survivors.
A retrospective study of patients 18—89 years old who required temporary mechanical circulatory support in the setting of ACS from August to August at University Medical Center at Lubbock, Texas.
A comparison between survivors and non-survivors to discharge was done. Elevated heart rates during mechanical support use and lactate at admission were associated to mortality bpm vs Elevated heart rates during mechanical support placement and lactate levels are associated with mortality in patients with cardiogenic shock secondary to an acute coronary syndrome. The initiation of mechanical support prior to PCI was associated to survival.
Larger more rigorous studies are needed to clarify these association. Managing hidradenitis suppurativa HS can be challenging. In many cases after initial conservative intervention, patients experience improvement in symptoms. Unfortunately, some cases become refractory and result in cosmetically challenging and painful recurrences. Surgery is often used to debride or excise affected tissue which can facilitate healing.
We present the case of a patient refractory to surgical intervention who was approached with superficial electron beam radiation therapy. A 44 year-old male presented with diffusely thickened buttocks, gluteal cleft, perineum, and bilateral thigh HS. The patient was refractory to surgical debridement and medical management via antibiotics and corticosteroids.
He was treated with split course electron beam radiotherapy, using a total dose of 30 Gray in 10 fractions and sustained a partial response within 2 weeks from initiation of treatment.
At that time, the patient reported subjective decrease in pain and drainage. The response was deemed durable at 6 and 12 months post-treatment. Radiation therapy has anecdotal benefit for a variety of benign conditions and has been studied in low doses, sometimes single fraction delivery in the management of HS.
We opted to use a split course which we believed was safest in mitigating side effects and potentially most durable. Treatment field for patient, displaying pre-treatment hidradenitis suppurativa in buttocks, gluteal cleft, perineum, and bilateral thighs. Superficial electron beam radiotherapy is effective in the management of benign conditions and has promise for refractory HS.
Total dose and fractionation schedules need to be studied to optimize and guide future use. Mitochondrial myopathies occur in one out of people in the general population of the United States. Clinical manifestations can be broadly classified into three categories: chronic progressive external ophthalmoplegia, skeletal muscle-CNS syndromes, or pure myopathy.
We present a case of bilateral lower limb weakness, pain, and swelling diagnosed with mitochondrial myopathy on muscle biopsy. Due to a traumatic tap, the lumbar puncture results for suspected Guillain-Barre syndrome were unreliable. An electrocardiogram showed left axis deviation with left anterior fascicular block. Due to declining maximal inspiratory pressures, the patient was admitted to the medical intensive care unit.
Ophthalmology confirmed ophthalmoparesis and ruled out cranial nerve palsy, myasthenia gravis, and retinitis pigmentosa. Gq1b antibody was negative. Extensive autoimmune and infectious work-up was non-contributory. Endomyocardial biopsy results revealed active lymphocytic myocarditis. The patient has been treated successfully with furosemide, metoprolol, and methylprednisolone.
Myopathies should be considered in the differential diagnosis of patients in whom Guillain Barre syndrome is suspected. We report an interesting case of myopathy with prominent cardiac manifestations. Myositis presenting with myocarditis should raise suspicion for mitochondrial disease. Our experience stresses the importance of using an inter-disciplinary team approach to diagnose uncommon pathologies with widely variable multi-systemic involvement.
The purpose of the study is to explore the possible diagnosis of Gaisbock in a patient with long-standing erythrocytosis and hypertension. A year-old Caucasian man with obesity was admitted with recurrent leg swelling and increasing oxygen requirements two weeks after hospitalization with COVID pneumonia. Recent medical history included a diagnosis of deep vein thrombosis DVT in the same leg two and a half months prior and was treated with Xarelto. The patient reported a history of low testosterone for 12 years.
However, he had not used any testosterone supplementation for the last nine months. He reported daytime fatigue, frequent bouts of nighttime awakenings, and frequent snoring. The patient never had a sleep study or used a CPAP.
The patient used half a can of chewing tobacco daily for thirteen years, and he smoked one pack per day for ten years but quit 12 years ago. He worked strenuous jobs in the construction industry most of his life. On review of previous records, the patient was found to have consistently elevated hemoglobin The patient had a stocky, ruddy appearance without hepatosplenomegaly.
Erythrocytosis can be categorized as primary, secondary, or relative. Patients with relative erythrocytosis have a decreased plasma volume with a relative increase in hemoglobin. Additionally, elevated hemoglobin levels have been associated with hypertension. It is associated with mild obesity, elevated blood pressure, and increased blood viscosity, which may explain why these patients often develop cardiovascular complications. Patients with relative erythrocytosis are at a higher risk for thromboembolic complications.
A year-old female with a past medical history of hypertension presented to the emergency department with a large, ulcerating mass on the dorsal aspect of her left hand. The patient reported the mass first appeared about two months prior to presentation and had been rapidly enlarging within the past week.
The patient also reported an associated pound weight loss over the past two months. Vital signs were stable. Labs were remarkable for iron deficiency anemia and thrombocytosis. MRI showed a large 9. MRA showed patent radial and ulnar arteries. There was evidence of vasculature feeding into the mass from the common palmar digital artery branches of the ulnar artery and deep palmar branches of the radial artery.
On physical examination, the large mass on the dorsal aspect of the left hand was friable and bleeding figure 1. The patient reported minimal pain. Sensation remained intact in the median, ulnar, radial and axillary distributions. The patient underwent excisional biopsy of the mass with amputation of the 4th and 5th digits.
Negative margins were achieved per frozen pathology. Pathology of the postsurgical specimen showed high- grade undifferentiated pleomorphic sarcoma UPS. Clinical suspicion for soft-tissue malignancy of the hand is usually low because most tumors of the hand are small and benign.
However, soft-tissue sarcomas of the hand are rapidly growing tumors with a high metastatic potential. UPS have no specific line of differentiation and are usually a diagnosis of exclusion. Patients with UPS are typically older in age compared to those with other soft tissue sarcomas.
The use of adjuvant chemotherapy for patients with resectable soft -tissue sarcoma remains controversial. Prior studies have shown a very small efficacy of chemotherapy in regards to recurrence and overall survival.
Although our patient had no evidence of metastatic disease at presentation, close follow-up with oncology will be necessary for surveillance of recurrence. Ulcerating soft-tissue mass of left hand measuring 8. The presence of chronic osteomyelitis may obscure the diagnosis of Marjolin ulcer. The present case report highlights this unique presentation to raise reasonable clinical suspicion and prevent missed diagnoses. While an initial shave biopsy was nonmalignant, a repeat biopsy six months later revealed indeterminant pathology.
At this time, she was referred to plastic surgery for an excisional biopsy. At presentation to plastic surgery, a nonhealing tibial wound with bone visible through a draining sinus tract was apparent within the boundaries of a previously healed scar. She reported a remote history of an open compound fracture requiring multiple surgical operations in the vicinity of the lesion.
An X-ray obtained to assess any residual hardware demonstrated findings consistent with osteomyelitis. Excisional biopsy revealed superficially invasive squamous cell carcinoma, consistent with a Marjolin ulcer.
At the time of her initial operation, a satellite lesion was identified and biopsied, revealing squamous cell carcinoma in situ. Marrow edema was observed in the screw path associated with hardware from her prior operations. Integra dermal substitute was placed while awaiting pathology results. Biopsy and culture of the affected bone revealed chronic osteomyelitis growing Staphylococcus lugdunensis.
The patient returned to the OR for full excision of the satellite lesion along with corticotomy and sequestrectomy of the affected bony tissue. A cement spacer with vancomycin and tobramycin was also placed at this time. Definitive coverage of the tibial defect was obtained with a soleus myocutaneous flap and split-thickness skin graft. Six weeks of outpatient cefazolin administration was arranged following discharge due to her chronic osteomyelitis.
Chronic immunosuppression, chronic infection, and multiple cutaneous neoplasms may be independently associated with the development of Marjolin ulcers. In the setting of atypical wound behavior, particularly when associated with these factors, clinical suspicion of secondary malignancy must remain high — even with prior negative biopsies and strong clinical evidence of an alternative diagnosis.
Varicella zoster virus lies dormant in the spinal dorsal root ganglia until reactivation occurs and causes Herpes zoster. With pain being the most common complication of Herpes zoster, other, more rare manifestations can be looked over. VZV can spread from the dorsal root to the neighboring ventral root and cause subsequent motor weakness. This usually occurs in the same anatomical region as the presenting rash, but the two can rarely be dissociated.
The majority of patient who develop segmental zoster paresis have a good prognosis and will recover all function after three to six months. In this case report, we present a year-old female who came to the hospital with altered mental status that was found to have right arm paralysis after resolution of her encephalopathy. Magnetic resonance imaging of the brain showed no acute infarction.
The patient had been diagnosed with Herpes zoster and prescribed gabapentin three days prior to admission with characteristic vesicular rash eruption present on the right upper extremity. Segmental zoster paresis was suspected at this point. She was started on IV acyclovir, and physical therapy was consulted. The patient remained hospitalized for 3 weeks awaiting discharge to inpatient rehab in which time she performed daily strength exercises for her arm.
IV acyclovir was given for 21 days. The rash resolved, and the patient was discharged to inpatient rehab for two weeks where she was recommended by PT to perform three hours of intensive therapy per day. Herpes zoster is a common disorder seen in older adults. Although we tend to focus on the associated pain, we must remember other possible manifestations that can occur during or after the initial rash presentation.
Segmental zoster paresis should be suspected in any patient with paralysis and recent diagnosis of shingles. Diabetes mellitus is a chronic disease with the potential for significant morbidity and mortality. Here we present spontaneous diabetic myonecrosis, a rare complication of diabetes mellitus, in a patient with CF. A year-old female with past medical history of CF, cystic fibrosis-related diabetes mellitus, diabetic retinopathy, exocrine pancreatic insufficiency presented to the hospital with severe right calf pain for 2 months associated with swelling.
She denied trauma or fever. Creatinine kinase and thyroid stimulating hormone were unremarkable. Ultrasound of lower extremities showed no evidence of deep vein thrombosis, and X-ray of the right leg was unremarkable. Magnetic resonance imaging MRI right leg showed nonspecific myositis noted throughout the calf with areas of nonenhancement and soft tissue edema. The Patient was diagnosed with mild diabetic ketoacidosis and diabetic myonecrosis of the right calf.
DKA was treated per protocol, low-dose aspirin was started, and symtomatic treatment was given with pain control for diabetic myonecrosis. Patient improved with no further complications. Spontaneous diabetic myonecrosis is a rare complication of diabetic mellitus. The pathogenesis is uncertain. Patients usually present with swelling and pain. The most common affected area is the front of the thigh, followed by the back of thigh or calf.
Awareness of the syndrome will frequently suggest the diagnosis and laboratory and imaging studies can be used to exclude other diagnoses. Interestingly, creatinine kinase is normal in many patients.
MRI may show high intensity in the involved muscle on T2-weighted sequences as well as subcutaneous edema and subfascial fluid. MRI with contrast is the diagnostic tool of choice which can distinguish nonenhancing infarcted muscle from surrounding inflammation or edema.
Muscle biopsy is not necessary; it is indicated only when the diagnosis remains in doubt or when infection cannot be excluded by other investigative techniques. Treatment includes rest, analgesia, low-dose aspirin, and optimal glycemic control. Complications including compartment syndrome and secondary infections are reported in some patients.
Spontaneous diabetic myonecrosis is a rare, debilitating complication of diabetes. The treatments are symptomatic treatment with analgesia, aspirin and optimize glycemic control. Without a high clinical suspicion for this condition, patients may be at risk for life- and limb-threatening progression to compartment syndrome and superimposed infection.
It is characterized by non-thrombocytopenic palpable purpura, abdominal pain, arthritis, and renal involvement. Pathologically, it can be considered a form of immune complex-mediated leukocytoclastic vasculitis LCV involving the skin and other organs. This is an year-old gentleman with CKD stage IV, coronary artery disease, status post stent placement, who presented withupper extremities pain, mild swelling, and a subsequent development of palpable rash that spread on the lower extremities while being nonpainful and with no itch.
He had mild proteinuria and microscopic hematuria notable in his urinalysis. Further deterioration of his kidney function was noted with normal complement levels and ANCA panel.
TEE ruled out infective endocarditis vegetations. The patient developed NSTEMI during his hospital stay prompting a percutaneous coronary intervention of the right coronary and left circumflex arteries. The rash and joint pain improved completely while his residual kidney function remained stable. There was no immediate improvement of kidney function after the plasmapheresis course of 5 days. The diagnosis can be easily missed. Accordingly, a high degree of suspicion and attention to noninvasive laboratory work culminating into kidney biopsy with immuno-fluorescence studies is mandatory to establish the diagnosis.
Adults with HSP carry a different prognosis, and the development of hematuria may be a harbinger for more serious complications such as nephritic or nephrotic syndrome.
Malignancy is common in adult-onset HSP and imaging should be done to exclude this possibility. Physicians should be aware of the possibility of HSP in patients who present with vasculitic rash and kidney disease.
Normal complement level can distinguish between IgA nephropathy and vasculitis like granulomatosis with angiitis and lupus erythematosus. Early diagnosis of HSP with kidney biopsy may improve the outcome.
He had tachycardia, tachypnea, and fever with an erythematous, tender wound on left index finger. He had lacerated his finger 2 weeks prior with a pocket knife while cleaning dirt under his fingernail and failed cephalexin and clindamycin oral therapies prior to admission.
Intravenous broad spectrum vancomycin and piperacillin-tazobactam were initiated and subsequently blood cultures grew Pasteurella multocida. He lived on a farm with a cat. In view of the implanted cardiac device, fever and positive blood cultures, infective endocarditis was a concern. However, transthoracic echocardiogram did not reveal any vegetations. XR and bone scan imaging of his finger also ruled out osteomyelitis. During his four days in the hospital, his condition and laboratory results improved and he was asymptomatic.
Follow up blood cultures were negative and patient was discharged home on oral amoxicillin clavulanate for another week duration. Pasteurella multocida is a commensal gram-negative bacteria seen in the mouths of many domesticated animals that is the most common cause of cellulitis after an animal bite. While it typically presents as soft tissue infections, it can more rarely cause meningitis, endocarditis, and bacteremia. It seems that contamination of the self-inflicted subungual minor wounds with cat saliva is what caused Pateurella multocida bacteremia.
The patient also presented with splinter hemorrhages. This physical exam finding is caused by rupture of capillaries underneath the nail plate. Blood attaches to the nail plate and moves distally as the nail grows, creating the characteristic linear pattern.
While the association between splinter hemorrhages and endocarditis is often emphasized in medical training, they are present in other pathologies as well and in and of themselves do not constitute a criteria for endocarditis. They most commonly appear due to trauma, but are also seen in endocarditis, vasculitis, medications, and renal failure due to platelet dysfunction from buildup of uremic toxins as was likely the case in this patient.
The patient was unlikely to have endocarditis since he became asymptomatic in 2—3 days and tested negative in repeat blood culture. Although a transesophageal echocardiogram would have been beneficial in definitively ruling it out infective endocarditis, a transthoracic echo of good quality is adequate especially in persons with prompt clinical improvement. Although it primarily attacks the respiratory system, the extrapulmonary targets of the virus include the gastrointestinal tract and hepatobiliary system, among others.
A year-old male with a past medical history of coronary artery disease, hypertension, 0. He denied shortness of breath, cough, fever, or chills. Physical examination was significant for epigastric tenderness. Normal troponin. CXR on admission showed mild patchy bibasilar infiltrates suggestive of developing pneumonia.
Right upper quadrant abdominal ultrasound showed no gallstones or other abnormalities within the pancreatobiliary system. CT abdomen and chest with and without contrast showed evidence of acute pancreatitis and no other abnormalities. It is designed so that it can plug and play interchangeably with different programs. She is a prime example of what happens after the shots and kills their argument well I took it and nothing happened.
Now she and everyone else who took these shots are playing the waiting game. Its coming. I feel for her and will pray for her. I am starting to see some of the effects in my own family. Its hard because you care for them and want to help them but there is nothing you can do. I tried hard as I could to try and convince them not to get it but they looked at me like I was insane.
In the end it was their own choice. I feel for you. No matter what you say or any evidence given, they will not accept it. The clot shots are safe and effective — they really believe this! I have kept my distance for my own sanity.
It is sad, horrifying and so frustrating. Just pray for them and bear witness. My family all got triple jabbed. Yet they still fail to believe what I tell them. Emptiness is springing from her eyes like a fountain from a pool. This is the age of emptiness and narcissism….
If the reference to 5g has something to do with the possible presence of graphene oxide in the vaccine, then that would really be the least of my concerns. Some researchers compare graphene oxide to asbestos even.
Apparently the EU devoted a billion euros to graphene research starting in There have been numerous studies looking at how graphene oxide can be used to fight bacteria and cancers and be used as a carrier mechanism in your body as well. It really is.
Then you read their social media posts and the sympathy meter enters negative territory. If you tell a child not to touch a hot stove and they do it anyway you will still have sympathy for the child. These adult covidians with their child-like minds you can only shake your head. Some things are just meant to be I guess.
I now have 0 sympathy for these people, 0. As because of them and their stupidity we were harrassed by the satate, rights being taken aways and so on discriminated greatly. The worse covid restrictions for unvaxed were in the countries with high compliance. High voluntary compliance. When they acheieved a critical mass, they satrted treating unvaxed as third class citizens, enemies, felons you name it lots of bad things and labels, selfish being the nicest of them all.
Sympathy I have for those taking the vax as being forced need to feed children, family, not needing to keep all priviledges and traveling this is luxury and we were all tested to see what is the most important: the money, status, momoa god u know or the light, difference between taking the vax to avoid dying of hunger or avoiding for keep all priviledges.
Also for those eldery that wre vaccinated in centers, or vulnerable that were lied by their doctors and had no means in educating themselves in regard with this vaccine. About the children and teens — no word, what they faced, they were betrayed by all those supposing to take care of them. Adults that wre exposed to the information, knew it but rejected as they chose to believe the msm propaganda… 0 sympathy. Good thing they are removed from the geene pool as they are entitled, mainly woke and totally selfish and well… stupid actuallyand very greedy.
So 0 for all these. The Covidians are starting to keep that info to themselves. I have had several tell me they regret getting the vaxx while acknowledging some health issues popping up. A couple asked me what stopped me from falling for the hysteria. I give them sites to read and tell them about all the red flags that led me to my decision. Louis, Mo Find articles by Robert W.

Methods This report represents a summary of an ad hoc multidisciplinary consensus teleconference and intervening e-mail communications held between March 31 and May 8, , conducted by a group of specialists with acknowledged expertise in the evaluation and treatment of TOS from across the United States, United Kingdom, and The Netherlands. There are few COVID patients, hospital resources are not exhausted, the institution still has ICU and ventilator capacity, the COVID trajectory is not in rapid escalation phase, and surgery is restricted to patients who are likely to experience compromised survival if it is not performed within the next 3 months.
Phase II, urgent setting. There are many COVID patients, ICU and ventilator capacity is limited, operating room supplies are limited, and surgery is restricted to patients whose survival is threatened if it is not performed within the next few days. Phase III, emergency setting. All hospital resources are routed to COVID patients, there is no ICU or ventilator capacity, operating room supplies are exhausted, and surgery is restricted to patients who may not survive if it is not performed within a few hours.
Open in a separate window. Results Recommendations regarding the evaluation and treatment of patients with suspected or established TOS were developed and described in relation to the three types of TOS neurogenic, venous, and arterial and for each phase of local institutional response to the pandemic. Venous TOS presenting with acute upper extremity deep venous thrombosis characteristic of Paget-Schroetter syndrome sudden spontaneous arm swelling, cyanosis, pain and heaviness, non-hemodynamically significant pulmonary embolism or positional axillary-subclavian vein compression without thrombosis should be managed primarily with anticoagulation until pandemic conditions resolve.
Evaluation and percutaneous interventions for venous TOS upper extremity venography, catheter-directed thrombolysis, and balloon angioplasty may be considered for arm swelling symptoms in pandemic phases I and II but should be reserved for rare limb-threatening situations presenting with massive arm swelling and severe pain phlegmasia cerulea dolens in phase III, with surgical treatment delayed until pandemic conditions resolve.
Catheter-based interventions may be considered for selected patients with central subclavian vein obstruction and threatened hemodialysis access in all pandemic phases, with definitive surgical treatment delayed until pandemic conditions resolve. Evaluation and treatment of arterial TOS should be reserved for limb-threatening situations, such as acute upper extremity ischemia or acute digital embolization, in all pandemic phases and in phases II and III should be restricted to a brachial artery approach to re-establish perfusion.
Definitive rib resection and arterial aneurysm repair should be deferred until phase I conditions return. Neurogenic TOS As the diagnosis of neurogenic TOS involves comprehensive review of medical records, evaluation of previous studies and treatments, and targeted physical examination in accord with established criteria, it is recommended that patients with suspected neurogenic TOS be referred to a specialist with expertise in management of this condition.
Venous TOS As the diagnosis of venous TOS involves comprehensive evaluation in accord with established criteria, it is recommended that patients with suspected venous TOS be referred to a specialist with expertise in management of this condition. Arterial TOS As the diagnosis of arterial TOS involves comprehensive evaluation in accord with established criteria, it is recommended that patients with suspected arterial TOS be referred to a specialist with expertise in management of this condition.

Discussion Paget-Schroetter syndrome PSS was introduced in AD by Hughes after a compilation of numerous case reports of upper extremity deep vein thrombosis UEDVT , which was assembled in recognition of the work by Paget in and Schroetter in where both described an association of acute venous stasis in a healthy person caused by repeated movements of shoulder girdle damaging the axillary vein, thus responsible for the formation of thrombus also known as traumatic thrombosis of the axillary vein [ 4 , 5 ].
Conclusions PSS is a classic example of a clinical condition needing a high index of suspicion and timely diagnosis. Human Ethics Consent was obtained or waived by all participants in this study.
