Emerging trends in pediatric candidemia: mapping the rise in Candida parapsilosis incidence and antifungal resistance in Turkey.

Candidemia is emerging as a significant concern in children, particularly among those with underlying conditions like malignancies or prematurity. The interpretation of epidemiological data on candidemias and their antifungal resistance plays a vital role in aiding diagnosis and guiding clinicians in treatment decisions. From 2014 to 2021, a retrospective analysis was conducted in İstanbul, Turkey; comparing Candida albicans and non-albicans (NAC) spp in both surviving and deceased groups.

Expert-opinion-based guidance for the care of children with lysosomal storage diseases during the COVID-19 pandemic: An experience-based Turkey perspective.

This expert-opinion-based document was prepared by a group of specialists in pediatric inherited metabolic diseases and infectious diseases including administrative board members of Turkish Society for Pediatric Nutrition and Metabolism to provide guidance for the care of children with lysosomal storage disorders (LSDs) during the COVID-19 pandemic in Turkey. The experts reached consensus on key areas of focus regarding COVID-19-based risk status in relation to intersecting immune-inflammatory mechanisms and disease patterns in children with LSDs, diagnostic virus testing, particularly preventive measures and priorities during the pandemic, routine screening and diagnostic interventions for LSDs, psychological and socioeconomic impact of confinement measures and quarantines and optimal practice patterns in managing LSDs and/or COVID-19. The participating experts agreed on the intersecting characteristics of immune-inflammatory mechanisms, end-organ damage and prognostic biomarkers in LSD and COVID-19 populations, emphasizing the likelihood of enhanced clinical care when their interaction is clarified further studies addressing certain aspects related to immunity, lysosomal dysfunction and disease pathogenesis.

Phenotypic Expansion of Congenital Disorder of Glycosylation Due to SRD5A3 Null Mutation.

We present a boy, admitted at 4 months, with facial dysmorphism, hypertrichosis, loose skin, bilateral inguinal hernia, severe hypotonia, psychomotor disability, seizures with hypsarrhythmia (West syndrome), hepatosplenomegaly, increased serum transaminases, iris coloboma, glaucoma, corneal clouding and bilateral dilated lateral ventricles, and extra-axial post-cerebellar space. Serum transferrin isoelectrofocusing (IEF) showed a type 1 pattern. Whole-exome genotyping showed a previously reported homozygous nonsense mutation c.

Screening Mucopolysaccharidosis Type IX in Patients with Juvenile Idiopathic Arthritis.

Mucopolysaccharidosis is a group of lysosomal disorders of a deficiency of specific enzyme required for glycosaminoglycan degradation. Mucopolysaccharidosis type IX is the rarest form of mucopolysaccharidosis. To date, only four patients have been reported.

Inherited metabolic disorders in Turkish patients with autism spectrum disorders.

Autism spectrum disorders (ASDs) are a major health problem because of their high prevalence in the general population. The pathophysiology of ASD remains unclear, although genetic defects may be detected in 10-20% of affected patients. Among these cases, the prevalence of inherited metabolic disorders (IMD) has not been extensively evaluated.

Lessons from two cases: is Fabry disease the correct diagnosis?

Fabry disease (FD) is an X linked inherited lysosomal storage disorder with complex multisystem involvement; it is caused by deficiency of the lysosomal enzyme α-galactosidase. Deficient enzyme activity leads to a wide spectrum of clinical manifestations consisting of dermatological, ophthalmological, cardiovascular, and urinary and central nervous system findings. As a result, FD should be considered in the differential diagnosis of many systemic diseases.

Biotinidase deficiency mimicking primary immune deficiencies.

Biotinidase deficiency (BD) is an inborn metabolic disorder inherited in an autosomal recessive manner. Partially due to high consanguinity rates in Turkey, BD incidence is high in Turkey. If left untreated, neurological abnormalities including seizures, hypotonia, sensorineural deafness, alopecia, egzamatous skin rash and candidiasis may occur.
