1. Genetic background of high myopia in childrenUrh Šenk, Bernard Čižman, Karin Writzl, Manca Tekavčič Pompe, 2024, original scientific article Abstract: Objective: High myopia is a significant risk factor for irreversible vision loss and can occur in isolation or as a component of various syndromes. However, the genetic basis of early-onset high myopia remains poorly understood. We aimed to identify the causative genetic variants for high myopia in a cohort of Slovenian children. Methods: The study included children referred to a tertiary paediatric ophthalmology centre at the University Eye Clinic in Ljubljana between 2010 and 2022. The participants met the following inclusion criteria: age ≤ 15 years and high myopia ≤-5.0 D before the age of 10 years. Genetic analysis included exome sequencing and/or molecular karyotyping. Participants were categorized based on clinical presentation: high myopia with systemic involvement, high myopia with ocular involvement, and isolated high myopia. Results: Genetic analysis of 36 probands revealed a genetic cause of high myopia in 22 (61.1%) children. Among those with systemic involvement (50.0%), genetic causes were identified in 13 out of 18 children, with Stickler's and Pitt-Hopkins being the most common syndromes. Among cases of high myopia with ocular involvement (38.9%), a genetic cause was found in 8 out of 14 probands, including (likely) pathogenic variants in genes related to retinal dystrophies (CACNA1F, RPGR, RP2, NDP). The non-syndromic ARR3- associated high myopia was identified in the isolated high myopia group. Conclusions: A genetic cause of high myopia was identified in 61.1% of children tested, demonstrating the value of genetic testing in this population for diagnosis and proactive counseling.

2. Association of asthma and anti-asthmatic therapy with oral health and microbiota alterations in children - a cross-sectional studyVojko Berce, Boris Egić, Anja Pintarič Lonzarić, Maja Rupnik, Aleksander Mahnič, 2026, original scientific article Abstract: Background: Asthma and its treatments are recognized as risk factors for oral health in children. The composition of oral microbiota is linked to asthma, as well as to the development of caries and other oral conditions. This study aimed to assess the impact of asthma and anti-asthmatic therapy on children`s oral health and explore the role of salivary microbiota in this relationship.
Methods: A cross-sectional study was conducted, including 100 children with asthma, aged 6 to 18 years, and 50 matched healthy controls. Oral health was assessed using the decayed, missing and filled teeth (DMFT/dft) index, the simplified oral hygiene index (OHI-S) to evaluate dental plaque and calculus, and the gingival index. Saliva flow rate and pH were measured, and the salivary microbiota composition was analyzed using 16 S amplicon sequencing. Results: Children with asthma had a median DMFT/dft index of 4, versus 0 in controls (p < 0.01), a median OHI-S of 0.9 versus 0 (p < 0.01) and a median gingival index of 1 versus 0 (p < 0.01). Daily use of inhaled corticosteroids (ICS) was associated with a higher median OHI-S (1 vs. 0.8, p < 0.01) but had no effect on the DMFT/dft or gingival index. The median unstimulated saliva flow rate and pH were 1.3 mL and 6.25 in children with asthma compared to 2.5 mL and 7.00 in controls (p < 0.01 for both). Children with asthma daily using ICS had a lower saliva flow (1.0 mL) and pH (6.25) compared to non-ICS users (1.5 ml and 6.75, p < 0.01 for both). The salivary microbiota composition in children with asthma differed significantly from controls (p < 0.01), showing increased abundances of Streptococcus, Gemella, and Streptobacillus. Alpha diversity was lower in children with asthma, with reduced richness (p < 0.01) and evenness (p = 0.012). However, no significant associations were identified between salivary microbiota and specific oral health indicators.
Conclusions: Asthma negatively affects children`s oral health, including reduced salivary flow, and is associated with alterations in the oral microbiota. However, the development of caries in children with asthma cannot be attributed solely to medications or microbiota alterations. Therefore, meticulous oral hygiene and other preventive measures are especially important in children with asthma.

3. Policy of fourteen maxillofacial divisions towards titanium plates removal after internal fixation of paediatric maxillofacial fractures : a World Oral Maxillofacial Trauma (WORMAT) projectGiulia Cremona, Serena Paione, Fabio Roccia, Sahand Samieirad, Marko Lazić, Vitomir Konstantinović, Euan Rae, Sean Laverick, Aleš Vesnaver, Anže Birk, 2024, original scientific article Abstract: Introduction: The aim of this 11-year retrospective multicentric study is to evaluate the policy of 14 maxillofacial surgery divisions in terms of titanium plate removal from paediatric patients who had undergone open reduction and internal fixation (ORIF) to treat maxillofacial fractures. Material and methods: Patients ≤ 16 years undergoing surgical treatment for fractures of middle and lower third of the face between January 2011 and December 2022, with a minimum follow-up of 6 months, were included. Age (group A: ≤ 6 years, B: 7−12 years, C: 13−16 years), sex, fracture location and type, surgical approach, number, and location of positioned and removed plates, timing and indications for removal were recorded. Results: 191/383 (50 %) patients (median age, 10 years; M:F ratio 2.1:1) underwent removal of 319/708 (45 %) plates. Maxillary dentoalveolar process (91 %), angle/ramus (63 %) and mandibular body (61 %) had a significantly higher removal rate than other fracture sites (p < 0.001). A significant decreasing trend in removal with increasing age was observed, from 83 % in Group A to 24 % in Group C (p < 0.001). On the total of positioned plates, 11 % were removed for symptomatic reasons (5 % infections, 6 % discomfort/pain) and 34 % for other reasons (28 % scheduled removal). Discussion: This multicentric study showed that plate removal was not performed routinely in the paediatric population. The incidence and causes of symptomatic plates removal were consistent with the literature, while the plate removal rate from asymptomatic patients was lower. A correlation was found between increasing age and a reduction in the frequency of plate removal procedures.

4. Open reduction and internal fixation of paediatric maxillozygomatic complex fractures : an 11-year multicentric retrospective studyFabio Roccia, Federica Sobrero, Carlo Strada, Gian Battista Bottini, Maximilian Goetzinger, Sahand Samieirad, Aleš Vesnaver, Anže Birk, Luis Fernando de Oliveira Gorla, Valfrido Antonio Pereira-Filho, 2024, original scientific article Abstract: Background/aim: Paediatric maxillozygomatic complex (MZC) fractures are uncommon, and there is a scarcity of data regarding their surgical treatment. The aim of this study was to analyse choices and outcomes of open reduction and internal fixation (ORIF) for MZC fractures among 14 maxillofacial centers around the world. Materials and Methods: This multicentric retrospective observational study included patients ≤16 years of age with quadripod MZC fractures treated with ORIF from January 2011 and December 2022. The following data were collected: age, gender, dentition stage (deciduous, mixed, and permanent), cause of injury, type of fracture, surgical approach, site of osteosynthesis (infraorbital rim, zygomaticomaxillary buttress, frontozygomatic, and zygomaticotemporal sutures), material (titanium or resorbable) and number of plates used, and outcome. The minimum follow-up was 6 months. Statistical analyses were performed with Fisher's exact test or chi-squared test, as appropriate. Results: Sixty-four patients (mean age, 12.3 years) with quadripod MZC fractures were included. Seventy-two percent of patients received a single-point fixation. The zygomaticomaxillary buttress was the most common site for fixation, both in singlepoint and two-point fixation schemes, especially in combination with the frontozygomatic suture. Increasing age was associated with a higher rate of plate removal (p< .001). Postoperative complications included 5 (7.8%) cases of wound infections, 2 (3.1%) infraorbital paraesthesia, 1 (1.6%) ectropion. Residual facial asymmetry was found in 5 (7.8%) patients and was not associated with the type of fixation (p> .05). Conclusions: This study highlights the possibility of using ORIF, even with a single point of fixation, for the treatment of displaced quadripod MZC fractures in the paediatric population. The zygomaticomaxillary buttress was the preferred site of fixation and allowed for adequate stabilization with no external scars and a low risk of tooth damage. Future prospective studies with long-term follow-up are needed to establish definitive surgical protocols and clarify the surgical decision-making.

5. An 11-year multicentric surgical experience on pediatric orbital floor trapdoor fracture : a World Oral Maxillofacial Trauma (WORMAT) projectPaolo Cena, Immacolata Raco, Fabio Roccia, Federica Sobrero, Emil Dediol, Boris Kos, Gian Battista Bottini, Maximilian Goetzinger, Sahand Samieirad, Luis Fernando de Oliveira Gorla, Aleš Vesnaver, Anže Birk, 2025, original scientific article Abstract: Introduction: Trapdoor fractures of the orbital floor occur almost exclusively in the paediatric population. Despite being widely discussed in the literature, their management remains controversial. The objective of this retrospective study was to analyse the surgical experiences on paediatric trapdoor fractures in the maxillofacial centres participating in the WORMAT project. Materials and methods: 14 centres collected data for patients aged ≤16 years operated between January 2011 and December 2022. The demographic, cause and type of fracture, timing from injury to surgery, surgical approach, type of floor repair and outcomes were recorded. Diplopia, surgical wound infection, hardware loosening and dysesthesia in the infraorbital nerve area were recorded at follow-up. Results: 43 patients were included: 25 children (0−12 y) and 18 adolescents (13−16 y) (mean age, 11.1 years). Surgical treatment was performed within 24 h in 51 % of the patients, within 24−72 h in 33 %, and beyond 72 h in the remaining. The orbital floor was repaired with a resorbable implant/membrane in 63 % of the patients, open reduction without an implant in 30 %, a titanium mesh implant in 3 adolescent patients. At follow-up (mean 16.3 months), 14 patients had residual diplopia in the upper fields, only two of these resolved within 6 months. Discussion: A tendency toward an increased incidence of postoperative diplopia with longer intervals between trauma and surgery was observed. This study showed different choices regarding the material placed on the floor, with a preference for open reduction without implants in children, compared to the use of resorbable implants or membranes in adolescents.

6. Multicentre retrospective study on plate osteosynthesis for non-condylar mandibular fractures in paediatric patients with deciduous, mixed, and permanent dentition : a world oral maxillofacial trauma (WORMAT) projectFederica Sobrero, Fabio Roccia, Valfrido Antonio Pereira-Filho, Luis Fernando de Oliveira Gorla, Anamaria Sivrić, Mario Kordić, Sajjad Abdur Rahman, Tabishur Rahman, Timothy Aladelusi, Karpal Singh Sohal, Aleš Vesnaver, Anže Birk, 2025, original scientific article Abstract: Mandibular fractures are common maxillofacial injuries among children and adolescents, but treatment remains controversial. The aim of this study was to analyse the methods and outcomes of open reduction and internal fixation (ORIF) for non-condylar mandibular fractures in paediatric patients among 14 maxillofacial centres. Patients ≤16 years of age undergoing ORIF for non-condylar mandibular fractures between 2011 and 2022 were included. Age, gender, dentition stage, site and type of fracture, surgical approach, material, thickness, and number of plates, and outcome were recorded. 179 patients (mean age, 11.1 years) reported 120 single and 59 double fractures, 79% involving at least one displaced or comminuted site. Single fractures were preferentially treated with rigid osteosynthesis in all dentition groups (64%), while double fractures with non-rigid osteosynthesis in mixed and permanent dentition patients (59% and 43%) and mixed osteosynthesis in deciduous dentition patients (50%). Mean follow-up was 21 months. Surgical would infection was the most common complication (8.9%), followed by minor malocclusion (1.7%) and osteitis (1.7%). In conclusion, the centres opted for fixation patterns like those recommended for adults, favoring non-rigid or mixed osteosynthesis for double fractures. The low complication rate shows ORIF is effective and safe for noncondylar mandibular fractures in paediatric patients.

7. Topical corticosteroid phobia in childhood atopic dermatitis : a study using the topicop scoreMateja Starbek Zorko, Vid Bukovec, Tanja Fantulin, 2026, original scientific article Abstract: Background: Topical corticosteroid phobia (CSP) is a significant barrier to the effective treatment of atopic dermatitis (AD). This is the first study to evaluate the CSP prevalence among parents of children with AD in Slovenia and to identify contributing factors. Methods: We conducted a cross-sectional study between March 2021 and December 2023. Parents of children with dermatologist-confirmed AD, aged 3 months to 18 years, completed the validated TOPICOP questionnaire, supplemental questions and the (F)DLQI questionnaire. The SCORAD index was used to assess the severity of their children's AD disease. Statistical analyses included the Shapiro-Wilk test, two-tailed independent t-test, ANOVA, followed by Tukey post hoc testing and the Pearson correlation coefficient. Results: Among 117 parents (81.2% mothers), the mean TOPICOP score was 48.2% (SD 15.1). Fear was the highest-scoring TOPICOP domain (53.7%). CSP was significantly higher in parents of children with more severe AD based on SCORAD (p = 0.033) and in families with higher (F)DLQI scores (r = 0.311, p = 0.002). Notably, our results suggest that parents of children in single-parent households had significantly higher CSP (p = 0.035), a novel finding that warrants cautious interpretation due to the small subgroup size. Information obtained online about the potential dangers of topical corticosteroids (TCS) correlated with higher CSP (p < 0.001). Conclusion: CSP is prevalent among Slovenian parents of children with AD and is particularly pronounced in cases of more severe disease and single-parent households, a novel and previously undescribed finding. Given that CSP is often influenced by nonmedical information sources, structured education and support by all healthcare providers is essential.

8. Disrupted vitamin D metabolism in hepatocellular carcinoma : free and bioavailable 25(OH)D as novel biomarkers of hepatic reserve and clinical riskJoško Osredkar, Matej Rakuša, Aleš Jerin, Borut Štabuc, Martin Zaplotnik, Saša Štupar, Darko Siuka, 2026, original scientific article Abstract: Background: Although total 25-hydroxyvitamin D (25(OH)D) measurements may not accurately reflect functional vitamin D status, vitamin D deficiency is common in hepatocellular carcinoma (HCC). The contribution of altered vitamin D-binding protein (VDBP) and albumin to impaired bioavailability is poorly characterized in liver cancer. Methods: We measured total, free, and bioavailable 25(OH)D, VDBP, and albumin in 46 HCC patients and 87 healthy controls during winter and summer. Correlations with Child–Pugh score, Barcelona Clinic Liver Cancer (BCLC) stage, and disease aetiology were evaluated. Results: HCC patients exhibited significantly lower VDBP (177.3 ± 237.0 vs. 239.9 ± 141.9 mg/L, p < 0.001) and albumin (35.9 ± 5.4 vs. 48.0 ± 3.9 g/L, p < 0.001) compared to winter controls. Total 25(OH)D was lower in HCC (39.3 ± 22.1 nmol/L) versus summer controls (75.0 ± 22.8 nmol/L, p < 0.001) but comparable to winter controls (p = 0.061). HCC patients lacked seasonal variation in vitamin D fractions, unlike the controls. VDBP negatively correlated with free (ρ = −0.606, p < 0.001) and bioavailable 25(OH)D (ρ = −0.541, p < 0.001). Child–Pugh score correlated positively with BCLC stage (ρ = 0.378, p = 0.012) and inversely with albumin (ρ = −0.565, p < 0.001). Conclusions: Free and bioavailable vitamin D are profoundly compromised in HCC, reflecting impaired hepatic synthetic function and systemic inflammation. These fractions may serve as novel metabolic biomarkers superior to total 25(OH)D for assessing vitamin D deficiency and guiding individualized supplementation strategies in patients with liver cancer.

9. Achievements, priorities and strategies in pediatric nephrology in Europe : need for unifying approaches or acceptance of differences?Jochen Ehrich, Velibor Tasić, Vidar O. Edvardsson, Evgenia Preka, Larisa Prikhodina, Constantinos J. Stefanidis, Rezan Topaloglu, Diamant Shtiza, Ashot Sarkissian, Tanja Kersnik-Levart, 2024, original scientific article Abstract: Background: There is a lack of information on the current healthcare systems for children with kidney diseases across Europe. The aim of this study was to explore the different national approaches to the organization and delivery of pediatric nephrology services within Europe. Methods: In 2020, the European society for Paediatric Nephrology (ESPN) conducted a cross-sectional survey to identify the existing pediatric nephrology healthcare systems in 48 European countries covering a population of more than 200 million children. Results: The reported three most important priorities in the care of children with kidney diseases were better training of staff, more incentives for physicians to reduce staff shortages, and more hospital beds. Positive achievements in the field of pediatric nephrology included the establishment of new specialized pediatric nephrology centers, facilities for pediatric dialysis and transplant units in 18, 16, and 12 countries, respectively. The most common problems included no access to any type of dialysis (12), inadequate transplant programs for all ages of children (12), lack of well-trained physicians and dialysis nurses (12), inadequate reimbursement of hospitals for expensive therapies (10), and lack of multidisciplinary care by psychologists, dieticians, physiotherapists, social workers and vocational counsellors (6). Twenty-five of 48 countries (52%) expected to have a shortage of pediatric nephrologists in the year 2025, 63% of clinical nurses and 56% of dialysis nurses. All three groups of health care professionals were expected to be lacking in 38% of countries. Prenatal assessment and postnatal management of renal malformations by a multidisciplinary team including obstetricians, geneticists, pediatricians, and pediatric surgeons was available in one third of countries. Conclusions: Our study shows that there are still very marked differences in pediatric health care systems across the European countries and highlights the need need for appropriate services for children with kidney disease in all European countries.

10. Hemoperfusion with CytoSorb® in pediatric patients : a monocentric case seriesEva Rihar, Vanja Peršič, Alexander Jerman, Tina Plankar Srovin, Gorazd Mlakar, Neva Bezeljak, Marko Pokorn, Petja Fister, 2024, original scientific article Abstract: Background: Pro- and anti-inflammatory cytokines help regulate the inflammatory response. A cytokine storm is a dysregulated cytokine response associated with sepsis and other conditions that result in a hyper-inflammatory state. Extracorporeal cytokine adsorption has the potential to restore a balanced inflammatory response. Hemoperfusion with CytoSorb® (CS) appears to be a short-term mode of treatment of sepsis in both adults and children. Objective: We present a case series of eight critically ill children involving the use of hemoperfusion with CS at the University Medical Center Ljubljana to treat clinically manifested cytokine storm. Results: In our preliminary experience, it was applied without complication in five children weighing more than 10 kg, who all survived. The effect of age on complications regarding CS treatment is unclear, yet in our case series, all three patients weighing less than 10 kg died of their disease. Conclusions: In our preliminary experience, cytokine adsorption with CS remains a potential adjunctive treatment for cytokine storm in critically ill children.
