Blood transcriptomic markers of necrotizing enterocolitis in preterm pigs.

Pediatr Res 2021 Jun 10. Epub 2021 Jun 10.

Comparative Pediatrics and Nutrition, Department of Veterinary and Animal Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.

Background: Necrotizing enterocolitis (NEC), a severe gut disorder in preterm infants, is difficult to predict due to poor specificity and sensitivity of clinical signs and biomarkers. Using preterm piglets as a model, we hypothesized that early development of NEC affects blood gene expression, potentially related to early systemic immune responses.

Methods: A retrospective analysis of clinical, tissue, and blood data was performed on 129 formula-fed piglets with NEC diagnosis at necropsy on day 5. Read More

ANCA-associated vasculitis after COVID-19.

Rheumatol Int 2021 Jun 7. Epub 2021 Jun 7.

Division of Nephrology, Department of Internal Medicine, Ondokuz Mayıs University Medical Faculty, Korfez Mahallesi, 55270, Atakum/Samsun, Turkey.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are systemic autoimmune diseases that may lead to renal failure due to the infiltration of mononuclear cells and the destruction of small- and medium-sized blood vessels. It has been shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may trigger the presentation or exacerbation of autoimmune diseases. Crescentic glomerulonephritis (GN) has rarely been reported in patients with Coronavirus disease-2019 (COVID-19). Read More

Successful Spinal Cord Stimulation for Necrotizing Raynaud's Phenomenon in COVID-19 Affected Patient: The Nightmare Comes Back.

Cureus 2021 Apr 19;13(4):e14569. Epub 2021 Apr 19.

Department of Intedisciplinary Medicine, University of Bari Aldo Moro, Bari, ITA.

Necrotizing Raynaud's phenomenon is a vascular clinical syndrome characterized by vasospasm of distal resistance vessels, usually triggered by cold temperatures or by psychological conditions such as anxiety and stress. Pain is the first reported symptom, related to insufficient oxygen delivery to the extremities that leads to ischemia of the peripheral tissues. The initial treatment is conservative, but if the symptoms persist, necrosis and distal amputation can occur. Read More

Introduction: Neurologic symptoms are an extremely rare presentation of Kikuchi-Fujimoto disease. We report a case of a young female patient diagnosed with Kikuchi-Fujimoto disease, presenting with neurologic symptoms compatible with aseptic meningitis, along with radiographic findings which improved with steroidal treatment. Despite the rarity of these findings, they were reported as part of the disease manifestation, however, since Kikuchi-Fujimoto disease is associated with other diseases, such as systemic lupus erythematosus (SLE), other diagnoses cannot be ruled out.

Case report of recurrent haemoptysis in an older patient with repaired tetralogy of Fallot.

Eur Heart J Case Rep 2021 May 17;5(5):ytab155. Epub 2021 May 17.

Department of Cardiovascular Diseases, Division of Congenital and Structural Cardiology, University Hospitals Leuven, Herestraat 49, 3000 Leuven, Belgium.

Background: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. Although most infants nowadays undergo surgical repair approximately at the age of 6 months with excellent outcomes, older patients typically underwent a staged approach with an initial systemic-to-pulmonary Blalock-Taussig-Thomas (BTT) shunt reducing hypoxaemia, followed by surgical TOF repair at an older age (with takedown of the BTT shunt). Late complications related to the BTT shunt are rare. Read More

Section for Comparative Pediatrics and Nutrition, Department of Veterinary and Animal Sciences, University of Copenhagen, Denmark.

Preterm infants are at high risks of sepsis and necrotizing enterocolitis (NEC). Some develop sepsis shortly after suspected or confirmed NEC, implying that NEC may predispose to sepsis but the underlying mechanisms are unknown. Using NEC-sensitive preterm pigs as models, we investigated the immune status in animals following development of sub-clinical NEC-like lesions with variable severities. Read More

Rhabdomyolysis Following Recovery from Severe COVID-19: A Case Report.

Am J Case Rep 2021 May 8;22:e931616. Epub 2021 May 8.

Oregon Health & Science University, Portland, OR, USA.

BACKGROUND Rhabdomyolysis occurs when muscle injury leads to the release of muscle cell constituents into circulation, often leading to significant systemic complications. There are many causes of rhabdomyolysis, and the etiology is often multifactorial or unclear. Current data suggest that acute COVID-19 may cause muscle injury that can lead to rhabdomyolysis, particularly in cases of severe illness requiring prolonged hospitalization; however, data on the long-term effects of COVID-19 on the musculoskeletal system are lacking.

Cureus 2021 Apr 1;13(4):e14236. Epub 2021 Apr 1.

Medicine/Neurological Intensive Care, Prisma Health Greenville Memorial Hospital, Greenville, USA.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, has proven neurotropism and causes a multitude of neurologic manifestations. Acute hemorrhagic necrotizing encephalitis (AHNE), though rare, can be seen in patients with severe infection and is associated with devastating neurologic outcomes. The true prevalence of this syndrome is unknown due to underrecognition, difficulty in timely acquisition of neuroimaging, and high mortality in this subset of patients escaping detection. Read More
