Clinical presentation and management challenges of sphingosine-1-phosphate lyase insufficiency syndrome associated with an SGPL1 variant: a case report.

Background: This case report describes a unique presentation of sphingosine-1-phosphate lyase insufficiency syndrome (SPLIS) caused by a rare SGPL1 variant, highlighting the diagnostic and management challenges associated with this condition.

Case Presentation: A 2-year-old Iranian female presented with steroid-resistant nephrotic syndrome (NS), primary adrenal insufficiency (AI), growth delay, seizures, and hyperpigmentation. Laboratory evaluation revealed hypoalbuminemia, significant proteinuria, hyperkalemia, and elevated adrenocorticotropic hormone (ACTH) levels.

Evaluation of the prevalence and clinical and laboratory features of acute viral myositis in children with influenza referred to the emergency department of Ali Asghar Tehran Hospital in 2019 and 2020.

Introduction: Influenza-related viral myositis is observed mostly in children with influenza, and the disease is more common in influenza type B. The aim of the present study was to evaluate the prevalence, and clinical and laboratory features of acute viral myositis in children with influenza in 2019 and 2020.

Methods: This retrospective cross-sectional study was performed in Ali Asghar Hospital, from December 2019 to February 2020.

The Resistance Rate of Helicobacter Pylori to Clarithromycin and Main Mutations on Bacterial Genomic Responsible for Bacterial Resistance: A Comparative Study in Children and Adults, Tehran and Iran.

Background: High resistance to common antibiotics has become a huge global dilemma in eradicating Helicobacter Pylori infection in both children and adults. The great concern is about the resistance to different classes of antibiotics especially Clarithromycin because of its widespread use.

Objectives: The present survey aimed to assess the resistance rate to Clarithromycin in Helicobacter Pylori isolated in patients aged less than 15 years as compared to patients older than 15 years of age.

Evaluation of procalcitonin as a biomarker of diagnosis, severity and postoperative complications in adult patients with acute appendicitis.

Background: Delay in diagnosis and treatment of acute appendicitis (AA) results in an increased rate of perforation, postoperative morbidity, mortality and hospital length of stay. Several biochemical parameters including white blood cell (WBC) count, C-reactive protein (CRP), interleukin-6 (IL6) and Procalcitonin (PCT) have been used to further improve the clinical diagnosis of AA. The aim of this study was to assess the value of procalcitonin as a predictor of diagnosis and severity of appendicitis in order to improve the clinical decision making, since other studies have been unable to demonstrate a diagnostic value for PCT elevation in acute appendicitis.

Risk factors of renal scars in children with acute pyelonephritis.

Objective: The aim of this study was to determine the association between previously documented risk factors such as recurrent pyelonephritis with the incidence of renal scarring after acute pyelonephritis in children.

Material And Methods: Children with acute pyelonephritis who were admitted to the Department of Pediatrics of a teaching hospital during 2007-2009 were enrolled in this study. DMSA scans were obtained 4-6 months after the last episode of pyelonephritis in all patients.
