Background: ADCY5-related dyskinesia is a rare disorder caused by mutations in the ADCY5 gene resulting in abnormal involuntary movements. Currently, there are no standardized guidelines to treat this condition.
Objective: The aim of this study was to evaluate the efficacy of theophylline administration in improving symptoms and quality of life in patients with ADCY5-related dyskinesia.
Background: Vascular endothelial growth factor D (VEGF-D) is a growth-factor involved in the development of blood vessels and lymphatics in tissues all over the human body. Interestingly, VEGF-D serum levels are increased in certain tumor entities. For tuberous sclerosis complex (TSC), a rare genetic disease associated with (benign) tumor growth, VEGF-D is already implemented as a diagnostic and therapeutic biomarker to monitor onset and progress of lymphangioleiomyomatosis (LAM), one of the noncancerous tumor manifestations in mainly female adult TSC patients.

This study assesses the impact of intraoperative neurophysiological monitoring (IONM) during postnatal myelomeningocele (MMC) repair and its potential to optimize functional outcomes.
Patients And Methods: Seven newborns with thoracolumbar or lumbar MMC underwent postnatal surgical repair using IONM.
: PTEN hamartoma tumor syndrome (PHTS) has evolved into an umbrella term for a range of syndromes, characterized by loss-of-function variants in the phosphatase and tensin homolog (PTEN) tumor suppressor gene on chromosome 10q23.31. This can result in a lifelong tumor predisposition in patients.

Patients: The intervention concept is designed for parents of children and adolescents aged 0-18 years with at least one long-term ASM.
Angelman syndrome (AS) is a rare neurogenetic disorder caused by a loss of function of on the maternal allele. Clinical features include severe neurodevelopmental delay, epilepsy, sleep disturbances, and behavioral disorders. Therapy currently evolves from conventional symptomatic, supportive, and antiseizure treatments toward alteration of mRNA expression, which is subject of several ongoing clinical trials.

For the first time, in 2014 updated guideline defines indispensable basic diagnostic measures and a consecutive algorithm for safe clinical decision making.
Patients And Method: We analyzed retrospectively 314 pediatric patients, 166 were presented before and 148 after publication of this guideline update.
Purpose: The aim of this study was to collect further data to estimate the risk of relevant intracranial pathology and thereby better assess the need for cranial imaging in children with acute acquired comitant esotropia (AACE). To date, there is still not enough literature on this topic to enable a consensus on the diagnostic algorithm.
Methods: We analyzed data from patients with convergent strabismus who received cranial imaging via magnetic resonance imaging (MRI).
Background: Creatine Kinase (CK) has become increasingly important in pediatrics as a commonly used laboratory screening parameter for neuromuscular diseases. Recent research suggests that hyperCKemia in children is not always associated with pathology and can occur due to several reasons. Little is known of various clinical factors that may influence CK throughout child development.

This study aimed to complement research from Leipzig 1994-2008 to seek trends within risk factors, treatments, and outcomes throughout the last decade. We retrospectively investigated data of 47 inpatients aged 0-18 admitted to Leipzig University Department of Pediatrics who matched ICD-10 code T75.

The aim of this cross-sectional study was to examine the influence of demographic characteristics on parenting stress from caring for a disabled child and to identify possible protective or additional stressful social factors. A total of 611 mothers and fathers of children with developmental delays, chronic diseases, or disabilities completed two questionnaires during their medical appointments at the Children's Development Center (CDC) of Leipzig University Hospital between June 2020 and February 2021.

To minimise this stress, stressful factors need to be known and stress needs to be recognised early. The present cross-sectional study aims to systematically assess and compare parenting stress in families of children with various types of disabilities.

Background And Purpose: Despite its rarity in Western countries, kernicterus resulting from severe neonatal hyperbilirubinemia and its associated neurologic consequences still persists. Subtle MR imaging patterns may be overlooked, leading to diagnostic and prognostic uncertainties. The study systematically analyzes MR imaging pattern over time.

In this retrospective observational study, we analyzed cerebrospinal fluid (CSF) samples in hydrocephalic diseases such as aqueductal stenosis (AQS, = 27), normal pressure hydrocephalus (NPH, = 24), hydrocephalus communicans (commHC, = 25) and idiopathic intracranial hypertension (IIH)/pseudotumor cerebri (PC, = 7) in comparison with neurological patients without hydrocephalic configuration (control, = 95). CSF was obtained through CSF diversion procedures and lumbar punction and analyzed for protein concentrations according to the institution's laboratory standards.

A comparison of cAMP levels was performed for ADCY5 wild-type and R418W mutant cells. ADCY5-catalyzed cAMP production was reduced with all three purine derivatives, while the most pronounced effects on cAMP reduction were observed for ADCY5 R418W mutant cells.

Macrocyclic contrast agents such as gadobutrol have so far escaped detection by qualitative MRI in children. This study aimed to assess whether there is evidence for deposition of gadobutrol in children using quantitative T1 mapping.

Background And Objective: The spectrum of myelin oligodendrocyte glycoprotein (MOG) antibody-associated disorder (MOGAD) comprises monophasic diseases such as acute disseminated encephalomyelitis (ADEM), optic neuritis (ON), and transverse myelitis and relapsing courses of these presentations. Persistently high MOG antibodies (MOG immunoglobulin G [IgG]) are found in patients with a relapsing disease course. Prognostic factors to determine the clinical course of children with a first MOGAD are still lacking.

The most widely applied DWI technique, a single-shot echo-planar imaging DWI (EPI-DWI) sequence, suffers from a high sensitivity to magnetic field inhomogeneities. As an alternative, a single-shot stimulated echo acquisition mode diffusion-weighted MRI (STEAM-DWI) has recently been re-introduced after it became significantly faster.

ATPase plasma membrane Ca transporting 1 (ATP2B1) belongs to the family of ATP-driven calmodulin-dependent Ca pumps that participate in the regulation of intracellular free Ca. Here, we clinically describe a cohort of 12 unrelated individuals with variants in ATP2B1 and an overlapping phenotype of mild to moderate global development delay.

In recent years, these pathways have moved into clinical focus because four of ten genes involved have been associated with a range of autosomal recessive rare diseases such as a neurodevelopmental disorder with muscular dystrophy (CHKB), bone abnormalities and cone-rod dystrophy (PCYT1A) and spastic paraplegia (PCYT2, SELENOI). We identified six individuals from five families with bi-allelic variants in CHKA presenting with severe global developmental delay, epilepsy, movement disorders and microcephaly.
