RESUMO
AIM: To determine the spectrum and frequency of disease-causing variants in patients with non-syndromic hearing loss (NSHL) and to investigate the diagnostic yield of the applied genetic methods. METHODS: The study enrolled 306 unrelated patients with childhood-onset, mild-to-profound NSHL referred to Children's Hospital Zagreb for genetic testing between March 2006 and October 2023. The GJB2 variants were analyzed with the multiplex ligation-dependent probe amplification method and Sanger sequencing of the coding region of the GJB2 gene. In 21 patients negative for GJB2 biallelic variants, clinical exome sequencing (CES) was performed. RESULTS: Among 234 disease-associated GJB2 alleles detected, 19 were clinically relevant, of which 18 were reported as pathogenic/likely pathogenic. The c.35delG variant accounted for 73.5% of the mutated alleles. More than half of the patients with biallelic GJB2 variants (64/110, 58.2%) were 35delG homozygotes. Seventeen non-GJB2 variants were found in 10 genes (TECTA, NOG, SLC26A4, PCDH15, TMPRSS3, USH2A, GATA3, MYO15A, SOX10, COL2A1) in 11 participants, and 5 variants (in TECTA, NOG, PCDH15, and SOX10) were novel (29.4%). CONCLUSION: We were able to elucidate the genetic cause of hearing loss in 121 patients, with an overall diagnostic rate of 39.5%. The c.35delG was the most common variant. CES allowed us to diagnose almost half of the patients with HL; to distinguish NSHL from the syndromic form of HL in cases where the phenotype was unclear or where symptoms were absent from an early age; and to discover novel variants.

Glycosylphosphatidylinositol anchoring disorders (GPI-ADs) are a subgroup of congenital disorders of glycosylation. GPI biosynthesis requires proteins encoded by over 30 genes of which 24 genes are linked to neurodevelopmental disorders. Patients, especially those with PIGA-encephalopathy, have a high risk of premature mortality which sometimes is attributed to cardiomyopathy. We aimed to explore the occurrence of cardiomyopathy among patients with GPI-ADs and to raise awareness about this potentially lethal feature. Unpublished patients with genetically proven GPI-ADs and cardiomyopathy were identified through an international collaboration and recruited through the respective clinicians. We also reviewed the literature for published patients with cardiomyopathy and GPI-AD and contacted the corresponding authors for additional information. We identified four novel and unrelated patients with GPI-AD and cardiomyopathy. Cardiomyopathy was diagnosed before adulthood and was the cause of early demise in two patients. Only one patients underwent cardiac workup after being diagnosed with a GPI-AD. All were diagnosed with PIGA-encephalopathy and three had a disease-causing variant at the same residue. The literature reports five additional children with GPI-AD related cardiomyopathy, three of which died before adulthood. We have shown that patients with GPI-ADs are at risk of developing cardiomyopathy and that regular cardiac workup with echocardiography is necessary.

Immunoglobulin A vasculitis (IgAV) or Henoch-Schönlein purpura is the most prevalent systemic small vessel vasculitis in childhood. High mobility group box 1 protein (HMBG1) is a pleiotropic cytokine that functions as a pro-inflammatory signal, important for the activation of antigen-presenting cells and propagation of inflammation. HMGB1 is implicated in the pathophysiology of a variety of inflammatory diseases. The aim of this study was to investigate the role of single nucleotide polymorphism rs41369348 for HMGB1 gene in the susceptibility and clinical features of patients meeting the classification criteria for IgAV. DNA was extracted from blood cells of 76 children with IgAV and 150 age-matched healthy controls. Clinical data and laboratory parameters were collected for all IgAV patients. Although there was a higher frequency of heterozygous A/delA genotype of this gene polymorphism in IgAV group as compared with control group, no genotype difference was observed between these two groups. No statistically significant genotype differences were disclosed when patients with different IgAV clinical features were compared. In conclusion, in this study, polymorphism rs41369348 for HMGB1 was not associated with increased susceptibility to childhood IgAV, its severity or different clinical manifestations.

The aim of this study was to determine the long term histopathologic changes in tracheal mucosa after a total laryngectomy , and to find out the relationship between the progression of histopathologic changes in tracheal mucosa and the duration of breathing through the tracheostomy. Tracheal mucosal biopsies were taken from a total of 35 patients, of both sexes, who underwent a total laryngectomy for laryngeal carcinoma at least one year prior. Histologic specimens of tracheal mucosa were stained with hematoxylin and eosin and examined under light microscopy. Almost all of the patients demonstrated histopathologic changes or abnormalities. Based on the results, histological findings were grouped into seven categories: normal respiratory epithelium, mild, moderate and advanced basal cell hyperplasia, squamous metaplasia, and slight and moderate and dysplasia. The time elapsed since surgery was calculated for each histopathological change separately. In laryngeal carcinoma patients, after a total laryngectomy histopathologic changes occur in tracheal mucosa. The mildest histopathological changes are found in the patients who had a longer period between the operation and the examination.

Total laryngectomy results in a permanent disconnection of the upper and lower airways. Thus, the upper airways are bypassed and can no longer condition, humidify, and filter the inhaled air, leading to damage of the tracheobronchial epithelium. There is little scientific information available about the effects of tracheostoma breathing and the degree of mucosal damage in laryngectomized patients. The aims of this study were to determine the histopathologic findings and investigate the potential impact of using a heat and moisture exchanger (HME) on the tracheal epithelium in long-term tracheostomy patients. Tracheal mucosal biopsies were taken from a total of 70 patients. Specimens were stained with hematoxylin and eosin and examined by a light microscope. Normal pseudostratified ciliated columnar epithelium was found in only 9 (12.9%) cases; while, 17 (24.3%) cases had some degree of basal cell hyperplasia. Squamous metaplasia was the most common finding (50%). Pre-invasive lesions (mild and moderate squamous dysplasia) were found in only one patient who used an HME, and in eight (11.4%) non-users. Although the HME cannot completely restore the physiological functions of the upper respiratory track, it delivers a better quality of air to the lower airways and has a positive effect on tracheal mucosa.

Lysosomal acid lipase deficiency is an autosomal recessive disorder with two distinct clinical phenotypes. Wolman disease is rapidly progressive with onset in early infancy. Complete enzyme deficiency results in massive accumulation of cholesterol esters and triglycerides in intestines, liver, spleen and other monocyte-macrophage system cells causing malabsorption, hepatosplenomegaly, liver failure and death in early infancy. Cholesterol ester storage disease may be diagnosed in childhood or later in life. It is characterized by chronic course and variable progression. Main features are variously expressed hepatopathy, including cirrhosis and liver failure, hypercholesterolemia and premature atherosclerosis. Characteristic is pathohistological finding of microvesicular steatosis and fibrosis and patognomonic are typical cholesterol ester crystals. Diagnosis is confirmed by enzyme assay and/or gene analysis. Until recently treatment was symptomatic. Ongoing clinical trials of enzyme replacement therapy have shown very promising results. We are presenting an infant with Wolman disease and two children with cholesterol ester storage disease with the aim to raise awareness about this disease and to start optimal care early.

Clinical features in patients with segmental aneuploidy often vary depending on the size of the chromosomal segment involved. Monosomy 2p is usually observed as a part of more complex syndromes among probands of balanced reciprocal translocation carriers. Patients with dup4q syndrome have variable clinical features, which are both related to the size of duplicated segment of the 4q and specific associated monosomy. Clinical findings of our patient were compatible with those previously reported in dup4q and del2p patients. Herein are presented the clinical and cytogenetic findings in a 4-year-old female with an unbalanced karyotype 46,XX,der(2)t(2;4)(p25.1;q31.3)pat. Clinical phenotypes of 2p;4q translocation cases are variable, because the involved breakpoints vary case-by-case. We also compare similarity of the clinical features of our proband and other patients carrying either duplication of the distal part of 4q and patients carrying a deletion of distal part of 2p as described in the literature. To our knowledge, this is the first case of partial trisomy 4q accompanied with partial monosomy 2p.

By using a combination of array comparative genomic hybridization and a candidate gene approach, we identified nuclear factor I/X (NFIX) deletions or nonsense mutation in three sporadic cases of a Sotos-like overgrowth syndrome with advanced bone age, macrocephaly, developmental delay, scoliosis, and unusual facies. Unlike the aforementioned human syndrome, Nfix-deficient mice are unable to gain weight and die in the first 3 postnatal weeks, while they also present with a spinal deformation and decreased bone mineralization. These features prompted us to consider NFIX as a candidate gene for Marshall-Smith syndrome (MSS), a severe malformation syndrome characterized by failure to thrive, respiratory insufficiency, accelerated osseous maturation, kyphoscoliosis, osteopenia, and unusual facies. Distinct frameshift and splice NFIX mutations that escaped nonsense-mediated mRNA decay (NMD) were identified in nine MSS subjects. NFIX belongs to the Nuclear factor one (NFI) family of transcription factors, but its specific function is presently unknown. We demonstrate that NFIX is normally expressed prenatally during human brain development and skeletogenesis. These findings demonstrate that allelic NFIX mutations trigger distinct phenotypes, depending specifically on their impact on NMD.

The aim of the study is identification of urinary tract infections (UTI) and urinary tract anomalies (UTA) already in the perinatal period. The authors attempted to prevent serious consequences of the above conditions in the examined children. Family history data, certain conditions in pregnancy and appertaining symptoms in children were elaborated to specify selective distinctive criteria for children at risk. Newborns (1200) were selected for potential existence of a UTI. All the examined newborns underwent a urinalysis. Those with significant bacteriuria were taken urine specimens, C-reactive protein (RVP), Complete Blood Count (CBC) and bilirubin. The newborns with a UTI and a suspected UTA were sent to ultrasound examination, direct radio nuclide cystography and Tc99m MAG3 dynamic scanning. The frequency of a UTI in the perinatal period amounted to 4.5%. A UTA was found in 29.6% of the examinees. The infection was more likely to appear among newborns with a UTA in their families, a UTI, pre-eclampsia and a febrile infection in mother, intrauterine growth retardation, premature rupture of membranes (RVP), umbilical cord strangulation, jaundice, cyanosis, breathing difficulties, seizures and asphyxia.

OBJECTIVE: The connection between increased dietary salt intake and arterial hypertension has been recognized for a long time, even in children. This study aimed to investigate salt consumption in normotensive and hypertensive children and evaluate their dietary habits. MATERIALS AND METHODS: A total of fifty participants were included in this cross-sectional study: twenty-five normotensive children and 25 children of both sexes with essential arterial hypertension from 12-17 years old. Subjects' body mass index, waist-to-hip ratio, body composition and arterial blood pressure were measured, and their daily salt intake was calculated from 24-h urine samples. Using the food frequency questionnaire (FFQ), the data on the average daily total energy and food intakes were collected and analyzed using a suitable program. RESULTS: Estimated daily salt intake was significantly higher in hypertensive compared to normotensive children, and this is positively associated with blood pressure and body mass index (BMI). Hypertensive children had significantly higher BMIs, which also positively correlated with blood pressure. Consistently, resting metabolic rate (kcal) is higher in hypertensive children compared to normotensive, and this is also associated with blood pressure. Reported energy intake is also enlarged in hypertensive compared to normotensive children and for both groups, levels are significantly higher than the recommended values. CONCLUSIONS: Our study results confirm the relationship between daily salt consumption, blood pressure and body weight. Sodium consumption related to blood pressure and body weight among children. Cardiovascular disease prevention should start in early childhood by reducing salt intake and preventing overweight/obesity since these are two of the most important modifiable risk factors for hypertension.

Gabriele-de Vries syndrome is a rare autosomal dominant genetic disease caused by de novo pathogenic variants in the Yin Yang 1 (YY1) gene. Individuals with this syndrome present with multiple congenital anomalies, as well as a delay in development and intellectual disability. Herein, we report the case of a newborn male patient with a novel de novo pathogenic variant in the Guanine Nucleotide-Binding Protein, Alpha Stimulating (GNAS) gene, which was identified by whole-exome sequencing. Our patient suffered from a large open spinal dysraphism which was treated surgically immediately after birth. During the follow-up, facial dysmorphism, bladder and bowel incontinence, and mildly delayed motor and speech development were observed. Congenital central nervous system disorders were also confirmed radiologically. In this case report, we present our diagnostic and treatment approaches to this patient. To our knowledge, this is the first reported case of Gabriele-de Vries syndrome presenting with spinal dysraphism. Extensive genetic evaluation is the cornerstone in treatment of patients with suspected Gabriele-de Vries syndrome. However, in cases with potentially life-threatening conditions, surgery should be strongly considered.
RESUMO
INTRODUCTION: Saul Wilson syndrome (SWS) is a rare congenital syndrome characterized by a variety of symptoms, mostly skeletal changes. Saul and Wilson were the first to describe children with extremely short stature and craniofacial dysmorphism. CASE REPORT: We present a case of a 15-years-old boy with clinical and radiological characteristics of SWS. Genetic examination identified a pathogenic heterozygous variant in the COG4 gene. Magnetic resonance imaging revealed a critical stenosis of the cranio-cervical junction (CCJ) which required surgical treatment to attempt sufficient neurological decompression. The patient underwent decompression of CCJ under general anesthesia. There was no significant radiological and clinical improvement during the postoperative period. CONCLUSIONS: SWS is presented as an extremely rare congenital disease in children. The clinical condition of our patient confined surgical possibilities, therefore further treatment in such patients should be appropriately evaluated.
RESUMO
Vitamin B12 (cobalamin) has two active forms, adenosylcobalamin and methylcobalamin which have a key role in two important metabolic pathways in humans and their deficiency is responsible for clinical problems. Cobalamin is essential during whole life, but its sufficient amount is extra important in fetal and neonatal period, when it is essential for normal child growth and development as well as for normal development of the central nervous system. Because of very complex transport and metabolism, its deficiency can be manifested in numerous congenital and acquired disorders. Vitamin B12 deficiency mostly has non-specific clinical features, it carries a great risk of permanent consequences, but most frequently it is easily curable if diagnosed on time. In Croatia cobalamin deficiency in children has been diagnosed too rarely. Accordingly, the aim of this paper is to point to the recently gained knowledge on cobalamin metabolism, present typical case reports and to provide guidelines for rapid and proper diagnostic and therapeutic approach.

Marshall-Smith syndrome (MSS) is a distinctive entity of unknown etiology with fewer than 50 patients described in the medical literature to date. Through an International collaboration and use of an online wiki to facilitate data collection and sharing, we further delineate the phenotype and natural history of this syndrome. We present 15 new patients, the oldest being 30 years, provide an update on four previously published cases, and compare all patients with other patients reported in literature. Main clinical features are moderate to severe developmental delay with absent or limited speech, unusual behavior, dysharmonic bone maturation, respiratory compromise secondary to upper airway obstruction, short stature, and kyphoscoliosis. Facial features are characteristic with high forehead, underdeveloped midface, proptosis, anteverted nares, and everted lips. Minor abnormalities of brain morphology such as hypoplasia of the corpus callosum are common. Mortality from respiratory complications is high, but airway support increasingly allows survival into adulthood. Array-CGH was performed on 12 of the cohort and no copy number variants of clear clinical relevance were identified. The present study is the first reported use of an online wiki to aid delineation of a genetic syndrome, and illustrates its value in collecting detailed data in rare conditions.

This article presents the case of a 5-month-old infant, who survived a fulminant meningococcal sepsis with purpura fulminans, septic shock and severe DIC with gastrointestinal bleeding. Amputation and reconstructive surgery were considered to treat the multiple skin and limb necroses at high risk of superinfection, but the surgical intervention was delayed due to the extremely doubtful outcome. On Day 10 after the onset of the disease, a hemodynamic improvement was achieved. The baby overcame early critical period, but was still in poor general condition. The hyperbaric oxygenation (HBO2) as adjuvant therapy was started in the monoplace chamber using the following protocol: from first through fifth day 45 minutes twice a day on 1.5 atmosphere absolute (ATA); after a two-day break, once a day on 1.8 ATA for 60 minutes. During 52 HBO2 treatments multiple areas of necrotic skin and subcutaneous tissue, together with fingertips and toes, detached spontaneously. All wounds healed without reinfections. An increased oxygen concentration during HBO2 therapy promoted spontaneous wound healing. Bacterial superinfection was not observed in numerous low-perfused lesions. Since repeated anesthesia and surgical interventions were not needed, a final invalidity was minimized. To the best of our knowledge, this is the first report on the successful conservative surgical treatment of this mutilating disease without aggressive reconstructive surgery in an infant with the help of HBO2.

BACKGROUND: Classic galactosemia is an autosomal recessive disorder of galactose metabolism caused by severely decreased activity of galactose-1-phosphate uridylyltransferase (GALT) due to pathogenic mutations in the GALT gene. To date more than 330 mutations have been described, with p.Q188R and p.K285N being the most common in Caucasian populations. Although acute manifestations can be fully avoided by a galactose-restricted diet, chronic complications, such as neurological ones, cannot be prevented in a significant number of patients despite compliance with the dietary treatment. METHODS: A cohort of 16 galactosemic Croatian patients, including one pair of siblings, was studied. Molecular characterization was performed by direct sequence analysis of the GALT gene. RESULTS: Sixteen patients were analyzed and only four different mutations were detected. As expected, p.Q188R and p.K285N were common, accounting for 40% and 37% of unrelated alleles, respectively. The third mutation accounting for 20% of mutant alleles was p.R123X causing a premature stop codon, is thus considered to be severe, which is in accordance with the phenotype presented by the homozygous patient described here. The fourth mutation p.E271D was found in a single allele. More than half of our patients manifested some chronic neurological complications. CONCLUSIONS: This is the first report on mutational and phenotypic spectra of classic galactosemia in Croatia that expands the knowledge on the mutational map of the GALT gene across Europe and reveals the genetic homogeneity of the Croatian population.

A surgical technique, materials used for abdominal wall reconstruction, and postoperative care are important for patient outcomes. We report the first case of neonate with Cantrell's pentalogy surviving early reconstruction of abdominal, diaphragmal and pericardial defects. Several recent investigations suggest that intraabdominal pressure monitoring may improve outcomes in this patient category.
RESUMO
The aim of the study was to detect newborns at risk for developing renal impairment, and to point out the importance of significant asimptomatic bacteriuria in perinatal period and early infancy. Severe urinary tract anomalies are very often accompanied only by asimptomatic bacteriuria in perinatal period. Three urinalysis ware done after delivery. 212 newborns with significant asimptomatic bacteriuria underwent ultrasound examination, and were followed up to three months. Those with normal findings and with passing bacteriuria in the first 2 months were excluded. Group of 52 newborns underwent radioisotope examination. Frequency of urinary tract anomalies in newborns was 34.6%. Increased risk for renal impairment had children with urinary tract anomalies in close family, urinary tract infection or bacteriuria, EPH gestosis and prepartal symptoms of febrile infection in mother, children with IUGR, strangulated umbilical cord, prolonged jaundice and attacks of peripheral cyanosis in perinatal period.
