Skin Health Dis 2021 Dec 15;1(4):e74. Epub 2021 Nov 15.

Department of Dermatology University of Texas Southwestern Medical Center Dallas Texas USA.

Background: Acute generalized exanthematous pustulosis (AGEP) is a severe pustular drug eruption with rare reports of haemodynamic instability.

Objective: To describe the clinical characteristics, management, and outcomes of patients with AGEP-associated haemodynamic instability.

Methods: This retrospective case series identified adult patients diagnosed with AGEP who had haemodynamic instability from November 2012 to February 2020 that were seen at two academic teaching hospitals with roles as a burn centre and tertiary referral centre at the University of Texas Southwestern Medical Center in Dallas, TX USA. Patients with a discharge diagnosis of AGEP that had haemodynamic instability during their eruption were included. Patients with a history of psoriasis, presentations thought to be a flare of generalized pustular psoriasis, or concurrent infection during eruption were excluded. AGEP with haemodynamic instability was characterized by degree of hypotension, dermatologic phenotype at time of dermatologic consultation, and management approach.

Results: This study included 19 patients with AGEP-associated haemodynamic instability (mean age, 52 years; age range, 29-76 years; 11 (58%) female). Patients were classified on a spectrum of haemodynamic instability; three had sustained hypotension, 10 had hypotension with organ dysfunction, and six had shock. Patients with AGEP-associated haemodynamic instability had a range of dermatologic phenotypes at initial consultation: subtle exanthematous eruption with minimal pustules, typical eruption with pustules and flexural predominance, and severe eruption with features of Stevens-Johnson syndrome. Both topical and systemic corticosteroids were used for treatment of several patients. Of the patients that required vasopressors and received systemic steroids, the majority were off vasopressors within 24 h of steroid initiation.

Conclusion: Approximately 22% of patients presenting with AGEP to a tertiary referral center had haemodynamic instability. Clinicians should be aware that dermatologic phenotype of AGEP at presentation does not correlate with development of haemodynamic instability.

Elevated Cardiac Troponin I following Asymptomatic Intradialytic Hypotension: A Pilot Study with a 2-Year Follow-Up.

Authors:
Toktam Alirezaei Mir Jafar Jebreil Moosavi Rana Irilouzadian Elahe Taziki

Int J Clin Pract 2022 1;2022:4214429. Epub 2022 Aug 1.

Clinical Research Development Unit of Shohada-e Tajrish Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background: Intradialytic hypotension (IDH) has been recognized as a serious and frequent complication during hemodialysis (HD) of end-stage renal disease (ESRD) patients, but the effect of asymptomatic IDH on cardiac troponin I (cTnI) levels is not definitively elucidated.

Methods: 70 asymptomatic HD patients with negative predialysis cTnI were included. They were on maintenance HD thrice weekly. Read More

Daniel Adimasu Kebede Yilikal Tafere Tewodros Eshete Ermias Abebaw Mekonen Adimasu Bekalu Endalew

PLoS One 2022 11;17(8):e0272571. Epub 2022 Aug 11.

Department of Public Health, College of Health Sciences, Debre Markos University, Debre Markos, Ethiopia.

Background: Trophic feeding is a small volume, hypo-caloric feeding, gut priming or minimal enteral feeding acclimate the immature gut of enteral fasting preterm neonates. Delayed starting of trophic feeding had resulted in short and long-term physical and neurological sequels. The current study aimed to estimate the time to initiate trophic feeding and its predictors among preterm neonates admitted in the neonatal intensive care unit of Debre Markos, Felege Hiwot, and Tibebe Ghion comprehensive specialized hospitals.

Common Supraventricular and Ventricular Arrhythmias in Children.

Authors:
Hasan Candaş Kafalı Yakup Ergül

Turk Arch Pediatr 2022 Aug 11. Epub 2022 Aug 11.

Department of Pediatric Cardiology, Pediatric Cardiac Electrophysiologist, University of Health Sciences, İstanbul Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital, İstanbul, Turkey.

The most common pediatric arrhythmias are tachycardias, and the most common type is supraventricular tachycardia, originating from or above the atrioventricular node and HIS bundle. Ventricular tachycardias are less common but more dangerous. Supraventricular tachycardias usually cause a narrow complex tachycardia unless there is a basal bundle branch block or rate-dependent aberration. Read More

Transfusion 2022 Aug 11. Epub 2022 Aug 11.

Department Immunopathology, Sanquin Blood Supply, Amsterdam, The Netherlands.

Background: Patients with severe thrombocytopenia due to bone marrow failure and after chemotherapy are still treated with platelet transfusions. Platelet concentrates (PC) are associated with a high incidence of adverse reactions (AR). Platelet-derived damage-associated molecular patterns (DAMPS) and complement were proposed to play a role in the pathology of AR. Read More

Introduction: Noonan syndrome (NS) is a dominant autosomal disease, caused by mutations in genes involved in cell differentiation, growth and senescence, one of them being RAF1 mutation. Congenital heart disease may influence the prognosis of the disease.

Case Presentation: We report a case of an 18 month-old female patient who presented to our institute at the age of 2 months when she was diagnosed with obstructive hypertrophic cardiomyopathy, pulmonary infundibular and pulmonary valve stenosis, a small atrial septal defect and extrasystolic arrhythmia.
