Pediatric stroke (PS) is an injury caused by the occlusion or rupture of a blood vessel in the central nervous system (CNS) of children, before or after birth. Hemiparesis is the most common motoric deficit associated with PS in children. Therefore, it is important to emphasize that PS is a significant challenge for rehabilitation, especially since the consequences may also appear during the child’s growth and development, reducing functional capacity. The plasticity of the child’s CNS is an important predecessor of recovery, but disruption of the neural network, specific to an immature brain, can have harmful and potentially devastating consequences. In this review, we summarize the complexity of the consequences associated with PS and the possibilities and role of modern rehabilitation. An analysis of the current literature reveals that Constraint-Induced Movement Therapy, forced-use therapy, repetitive transcranial magnetic stimulation, functional electrical stimulation and robot-assisted therapy have demonstrated at least partial improvements in motor domains related to hemiparesis or hemiplegia caused by PS, but they are supported with different levels of evidence. Due to the lack of randomized controlled studies, the optimal rehabilitation treatment is still debatable, and therefore, most recommendations are primarily based on expert consensuses, opinions and an insufficient level of evidence. © 2024 by the authors.

In this study we aimed to explore how managers in primary health care (PHC) organizations assess their managerial knowledge and skills, as well as the importance of these competencies for their job, and to identify whether there is an alignment between these two perceptions; therefore, whether there is a need for management competency improvement. With this study, we tried to address a high demand for information about health managers, especially in health systems in low-and middle-income countries. In a sample of 58 primary health care centers (n = 106 managers) in Serbia, we used a basic managerial competency matrix consisting of the following six competencies—communication, team-building, planning and priority-setting, performance assessment, problem-solving, and leading. Managerial perception of the importance of their job tasks differs by educational level and managerial position. The best alignment between the importance of knowledge and skills was for communication and leading. The study pointed out that managers were aware of the necessity to improve their level of managerial competencies, particularly in the domains of planning and priority-setting, performance assessment, and problem solving. The study highlights the need for formal managerial education for managers in PHC settings and commitment to continuously evaluate and improve management competencies in order to better manage PHC. © 2019 by the authors.

Background and objectives: The purpose of this study is to investigate the differences in the degree of the anxiety and comorbidity levels in patients with different chronic pulmonary diseases such as chronic obstructive bronchitis (COPD) without emphysema phenotype, pulmonary emphysema, bronchial asthma and lung cancer. Materials and Methods: The prospective clinical study included 272 patients that were diagnosed and treated of pulmonary pathology. COPD (without emphysema phenotype) (Group-1), pulmonary emphysema (Group-2), bronchial asthma (Group-3) and lung cancer (Group-4) were assessed. For the evaluation of the anxiety degree, we used Hamilton Anxiety Rating Scale (HAM-A). Results: The degree of cardiovascular symptoms was significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p = 0.001) and Group-4 (p = 0.013), and significantly higher in Group-4 versus Group-2 (p = 0.046). The degree of respiratory symptoms was significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p <0.001) and Group-4 (p = 0.002), and significantly higher in Group-4 versus Group-2 (p = 0.013) and versus Group-3 (p = 0.023). For gastrointestinal symptoms, the degree of one was significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p < 0.001) and Group-4 (p = 0.017). Somatic subscale values were significantly higher in Group-1 versus Group-2 (p < 0.001), Group-3 (p <0.001) and Group-4 (p = 0.015), and significantly higher in Group-4 versus Group-2 (p = 0.024). Total HAM-A score was significantly higher in Group-1 versus Group-2 (p = 0.002) and Group-3 (p = 0.007). Conclusions: Patients with COPD (without emphysema phenotype) followed by the lung cancer are at elevated risk of being more mentally challenged in terms of increased anxiety. Furthermore, patients with exacerbation of evaluated pulmonary pathologies have various levels of comorbidities degrees. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

Background: Surgical resection remains an important treatment of choice for a large number of liver tumors in children. Sometimes, if a tumor infiltrates a large part of the liver, after resection, the future liver remnant (FLR) is not enough for normal liver function. The size of the FLR is one of the determining factors for resectability as postoperative liver failure (PLF) is the most severe complication after partial hepatectomy. A new strategy for treating marginally resectable liver tumors in adult patients which were initially considered as unresectable was formally reported in 2011. This operative technique is a hepatectomy consisting of two stages with initial portal vein ligation and in situ splitting of the liver parenchyma. In 2012, the acronym “ALPPS” (associating liver partition and portal vein ligation for staged hepatectomy) was proposed for this novel technique. However, there is a small number of ALPPS procedures performed in pediatric patients published in the literature. Objectives: The aim of this paper is to present the first case of a pediatric patient with a marginally resectable rhabdoid tumor of the liver which was initially considered unresectable and who was treated with two-stage hepatectomy. We report a case of a 4-month-old girl with a large rhabdoid tumor of the liver who underwent this procedure. Conclusions: ALPPS can be a valuable technique to achieve complete resection of pediatric liver tumors although indications for ALPPS in children still need further research mainly focused on validation of the minimally needed FLR in children undergoing extended liver resections. To our knowledge, this is the youngest patient on whom ALPPS was performed, and the only one with a rhabdoid tumor. © 2025 by the authors.

Background and Objectives: During the COVID-19 pandemic, a possible overlap of obesity and COVID-19 infection has raised concerns among patients and healthcare professionals about protecting pregnant women from developing a severe infection and unwanted pregnancy outcomes. The aim of this study was to evaluate the associations of body mass index with clinical, laboratory, and radiology diagnostic parameters as well as pregnancy complications and maternal outcomes in pregnant patients with COVID-19. Materials and Methods: Clinical status, laboratory, and radiology diagnostic parameters and pregnancy outcomes were analyzed for pregnant women hospitalized between March 2020 and November 2021 in one tertiary-level university clinic in Belgrade, Serbia, due to infection with SARS-CoV-2. Pregnant women were divided into the three sub-groups according to their pre-pregnancy body mass index. For testing the differences between groups, a two-sided p-value <0.05 (the Kruskal–Wallis and ANOVA tests) was considered statistically significant. Results: Out of 192 hospitalized pregnant women, obese pregnant women had extended hospitalizations, including ICU duration, and they were more likely to develop multi-organ failure, pulmonary embolism, and drug-resistant nosocomial infection. Higher maternal mortality rates, as well as poor pregnancy outcomes, were also more likely to occur in the obese group of pregnant women. Overweight and obese pregnant women were more likely to develop gestational hypertension, and they had a higher grade of placental maturity. Conclusions: Obese pregnant women hospitalized due to COVID-19 infection were more likely to develop severe complications. © 2023 by the authors.

Background. Epileptic seizures might be associated with an increased risk of fractures, either as a result of trauma after a fall or as a result of excessive muscle contraction. In the pediatric population, excessive muscle contraction is a more significant risk factor for fractures, due to the lack of maturity in the musculoskeletal system, while antiepileptic therapy itself can lead to a reduction of bone density. Proximal humeral fractures in the pediatric population are not frequent but both proximal humeral fractures and shoulder dislocation increase the chance of brachial plexus injuries and peripheral nerve lesions. Case. In this case report, we present a patient who suffered both avulsive greater tuberosity humeral fracture and anterior shoulder dislocation, initially diagnosed by radiography, with consequent brachial plexus injury of the left arm after an epileptic seizure followed by excessive muscle contraction. Electromyoneurography initially showed amplitudes’ reduction in tested nerves along with signs of muscle denervation as well as clinical examination signs of the left arm muscular hypotrophy and hypoesthesia, especially in the left humero-scapular region. Electrotherapy and kinesitherapy as well as intramuscular dexamethasone injections administered three weeks after the injury finally improved the clinical examination findings in the patient. Conclusion. The early detection of swelling compression, accompanied with appropriate therapy may prevent the progression of axonal damage and preserve the functional status of the affected limb. © 2021, Turkish National Pediatric Society.

Background: Recognized as one of the most serious musculoskeletal deformities, occurring in 1–2 per 1000 newborns, 80% of clubfeet are idiopathic while 20% present with associated malformations. The etiopathogenesis of clubfoot is described as multifactorial, including both genetic and environmental risk factors. The aim of this study was to analyze possible genetic causes of isolated and syndromic clubfoot in Serbian children, as well as to correlate clinical and genetic characteristics that would provide insight into clubfoot etiopathogenesis and possibly contribute to global knowledge about clinical features of different genetically defined disorders. Methods: We evaluated 50 randomly selected, eligible children with clubfoot aged 3 to 16 years that were initially hospitalized and treated at University Children’s Hospital between November 2006 and November 2022. The tested parameters were gender, age, dominant foot, affected foot, degree of deformity, treatment, neuromuscular disorders, positive family history, and maternal smoking. According to the presence of defined genetic mutation/s by whole exome sequencing (WES), patients were separated into two groups: positive (with genetic mutation/s) and negative (without genetic mutation/s). Results: Seven patients were found to be positive, i.e., with genetic mutation/s. A statistically significant difference between categorical variables was found for families with a history of clubfoot, where more than half (57.14%) of patients with confirmed genetic mutation/s also had a family history of genetic mutation/s (p = 0.023). Conclusions: The results from this study further expand the genetic epidemiology of clubfoot. This study contributes to the establishment of genetic diagnostic strategies in pediatric patients with this condition, which can lead to more efficient genetic diagnosis. © 2024 by the authors.

Objectives: A tribomechanically activated clinoptilolite (natural aluminosilicate mineral) has been used to increase growth in meat-producing animals, as an adjuvant in cancer therapy, and a heavy metal remover in humans. Because of its unique cation exchanging and chelating properties, we hypothesized that clinoptilolite may be beneficial for the treatment of dyslipidemia in the manner similar to bile acid sequestrants. Thus, specific aims of this pilot study were to orally administer clinoptilolite in different doses and granule size combinations to determine magnitude and time profile of changes in blood lipids. Design: A phase I/IIa prospective, open-label, uncontrolled, dose/granule size-ranging study (treatment phase 8 weeks, follow-up 6 weeks). Blood lipids were examined every 2 weeks. Settings: Outpatient clinic of a university-affiliated hospital. Subjects: Forty-one subjects (all white, mean age 57.6 ± 6.8 years, 17 women) with blood lipids above the normative limits divided into three groups. Intervention: A tribomechanically activated clinoptilolite was administered in three dose/grind combinations: 6 g/day of fine grind (6gF), 6 g/day of coarse grind (6gC), and 9 g/day of coarse grind (9gC). Outcome measures: Blood concentrations of total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), high-density lipoprotein cholesterol (HDLc), and triglycerides (TG). Results: For the 3 groups combined, all lipid fractions significantly improved after 8 weeks of treatment (20-25%, p < 0.001), which reversed to baseline after 6 weeks of clinoptilolite withdrawal. Early (week 2) and the most pronounced decrease in TC and LDLc was observed in the 6gF group (19% and 23% in week 8, respectively), with no difference in HDLc and TG between the three dose/grind groups. No side effects were reported. Conclusions: These pilot results suggest that oral administration of clinoptilolite may improve lipid profile in individuals with dyslipidemia, which warrants further investigations. © Copyright 2017, Mary Ann Liebert, Inc.

Objective: To analyze the impact of rehabilitation treatment on social functioning in elderly patients after hip fracture during a rehabilitation program. Methods: This study included 203 patients with hip fracture. Four groups were analyzed on rehabilitation: Group 1, at admission, Group 2, at discharge, Group 3, three months after discharge and Group 4, six months after discharge. The analyzed parameters included: Musculoskeletal, neurological and cognitive impairments. Impairment severity was graded by cumulative index rating scale for geriatrics (CIRS-G). Evaluation of social functioning was completed by social functioning component (SFC) from quality of life (SF-36) questionnaire. Results: There was a significant improvement in SF-36 SFC values for observed impairments from admission to six months after discharge for each severity degree (p < 0.01), except for CIRS-G severity degree 4 for cognitive impairment, where significance was p < 0.05. For the group of patients with musculoskeletal impairment, there was a significant difference between the values of SF-36 SFC concerning different severity degrees of CIRS-G only at six months after discharge (p < 0.05). Patients with neurological or cognitive impairments have shown significant differences between the values of SF-36 SFC in regard to severity degrees of CIRS-G in all observational groups. Conclusion: Different degrees of observed impairments influence the degree of social functioning recovery in the elderly after hip fracture.

Objective: Aim of our study was to evaluate distribution of ABO and Rh blood type groups in children after hip surgery regarding transfusion administration and fever presence. Methods: Four types of ABO blood groups (A; B; AB; O) and 2 types of Rh blood groups (Rh+; Rh-) were evaluated in group with administered transfusion (tr+) and without given transfusion (tr-); and in group with fever (fev+) and without fever (fev-), in 146 children after hip surgery. Tr+ and fev+ groups were divided into 3 groups (0-24h; 25-48h; 49-72h): for tr+ group (Group 1, Group 2, Group 3), and for fev+ group (Group A, Group B, Group C). Results: AB blood group significantly decreased in Group 1 (χ2= 6.44; p<0.05) and A blood group in Group 3 in tr+ group (χ2= 7.68; p<0.01). O blood group significantly increased in Group 3 in tr+ group (χ2= 9.96; p<0.01). AB blood group significantly decreased in Groups B (χ2= 12.2; p<0.01) and C (χ2= 4.2; p<0.05) in fev+ versus fevgroup. B blood group significantly increased in Group C (χ2= 34.4; p<0.01) in fev+group. Conclusion: Administration of transfusion and fever onset in pediatric patients undergoing surgical correction of the hip is not influenced by the ABO and Rh blood groups system in humans. There is correlation between distribution of ABO blood groups with the time of transfusion administration and fever onset in children after hip surgery.

Aortic coarctation surgery in pediatric patients requires the placement of two arterial cannulas to monitor pressure gradients and surgical correction adequacy. Near-infrared spectroscopy (NIRS) monitoring provides insight into regional blood flow. This study aimed to investigate the correlation between NIRS values and invasive arterial pressures, exploring NIRS monitoring as a potential substitute for arterial cannulation. In a cohort of 21 consecutive pediatric patients undergoing aortic coarctation surgery, recordings of NIRS and invasive arterial pressure values were evaluated at various time intervals. Pearson correlation evaluated the relationship between NIRS values and invasively measured arterial pressures. Moderate to strong correlations were observed between the mean arterial pressure (MAP) of the upper and lower arteries and cerebral (rSO2-C) and somatic (rSO2-S) NIRS values 5 min after cross-clamp placement (r = 0.621, p = 0.003; r = 0.757, p < 0.001). Strong correlations were found 15 min after cross-clamp placement (r = 0.828, p = 0.002; r = 0.783, p = 0.004). Before transfer to the ICU, a strong correlation existed between the upper artery MAP and rSO2-C (r = 0.730, p < 0.001), but there was no correlation between the lower artery MAP and rSO2-S. These findings are promising, but further studies are required to validate it as a reliable substitute for invasive pressure monitoring in this patient population. © 2024 by the authors.

Background and objective: Dysfunctional voiding (DV) presents relatively frequent problem in pediatric urologist practice. The necessity for implementation of DV evaluation in the pediatric population is of particular importance, since there is no clear consensus on the clinical assessment of such condition. The aims of our study were to evaluate the test/retest reliability and reproducibility of dysfunctional voiding and incontinence scoring system: Serbian version (DVISSSR) in patients with voiding and incontinence dysfunctions without structural deformities, and to estimate cut-of value for DVISS SR . Methods: The cross-sectional study included 57 children with voiding and incontinence dysfunctions and 30 healthy pediatric controls. For the evaluation of voiding and incontinence dysfunction we used DVISS. The forward-backward method was applied for translation of the DVISS questionnaire from English into Serbian language. Reproducibility was analyzed by Interclass Correlation Coefficient (ICC). Sensitivity and specificity of DVISS SR scores was done by receiver operating curve (ROC) curve. Results: There was a significant difference in DVISS SR score between patients and controls (p < 0.001). For reliability and reproducibility of the questionnaire, there was no significant difference between repeated measurements (p = 0.141), and strong reliability (ICC = 0.957; p < 0.001). Conclusion: We have demonstrated successful translation and validation of the DVISSSR score. Moreover, a reliable scoring system of children with voiding dysfunctions should include evaluations of symptom scoring systems at the multicentric level. © 2019 by the authors.

Introduction: Assuming that spina bifida (SB) is a genetically controlled disease, the aim of our study was to evaluate the degree of genetic homozygosity and the distribution of AB0 blood types among patients with SB occulta and SB aperta by the homozygously recessive characteristics (HRC) test. Material and methods: Our study included an analysis of the presence, distribution and individual combination of 15 selected genetically controlled morpho-physiological traits in a sample of 100 patients with SB (SB occulta N = 50 and SB aperta N = 50) and a control group of individuals (N = 100). Results: We found a statistically significant difference between the mean values for genetic homozygosity (SB 4.5 ±0.3; control 3.0 ±0.2, p < 0.001) and also differences in the presence of certain individual combinations of such traits. In 12 (80.0%) of the 15 observed characteristics, recessive homozygosity was expressed to a greater degree among the group of SB patients, while for 9 (60.0%) of the traits this level of difference was statistically significant (Σx2 = 266.3, p < 0.001). There was no difference in average homozygosity of such genetic markers between groups of SB occulta and SB aperta patients, but the type of individual variation in the two studied groups significantly differed. In the group of patients with SB the frequency of 0 blood group was significantly increased while B blood group was significantly decreased. Conclusions: Our results clearly show that there is a populational genetic difference in the degree of genetic homozygosity and variability between the group of patients with SB and individuals without clinical manifestations, indicating a possible genetic component in the aetiopathogenesis of spina bifida.

Background/Objectives: Prediction of a difficult airway during pre-anesthetic evaluation is of great importance because it enables an adequate anesthetic approach and airway management. As there is a scarcity of prospective studies evaluating the role of anthropometric measures of the face and neck in predicting difficult airways in infants with an apparently normal airway, we aimed to identify the aforementioned predictors of difficult facemask ventilation and intubation in infants. Methods: A prospective, observational study that included 97 infants requiring general endotracheal anesthesia was conducted. Anthropometric and specific facial measurements were obtained before ventilation and intubation. Results: The incidence of difficult facemask ventilation was 15.5% and 38.1% for difficult intubation. SMD (sternomental distance), TMA (tragus-to-mouth angle distance), NL (neck length) and mouth opening were significantly lower in the difficult facemask ventilation group. HMDn (hyomental distance in neutral head position), HMDe (hyomental distance in neck extension), TMD (thyromental distance), SMD, mandibular development and mouth opening were significantly different in the intubation difficulty group compared to the non-difficult group. HMDn and HMDe showed significantly greater specificities for difficult intubation (83.8% and 76.7%, respectively), while higher sensitivities were observed in TMD, SMD and RHSMD (ratio of height to SMD) (89.2%, 75.7%, and 70.3%, respectively). Regarding difficult facemask ventilation, TMA showed greater sensitivity (86.7%) and SMD showed greater specificity (80%) compared to other anthropometric parameters. In a multivariate model, BMI (body mass index), COPUR (Colorado Pediatric Airway Score), BOV (best oropharyngeal view) and TMA were found to be independent predictors of difficult intubation, while BMI, ASA (The American Society Physical Status Classification System), CL (Cormack–Lehane Score), TMA and SMD predicted difficult facemask ventilation. Conclusions: Preoperative airway assessment is of great importance for ventilation and intubation. Patient’s overall condition and facial measurements can be used as predictors of difficult intubation and ventilation. © 2024 by the authors.

Introduction: Patients with spina bifida in the lumbosacral region usually have various degrees of motor and sensory dysfunctions of the lower extremities and anal sphincter. The aim of our study was to evaluate the distribution and differences in frequencies of affected muscles, number of affected muscles and degree of neurogenic lesion between patients with spina bifida occulta (SBO) and spina bifida aperta (SBA). Material and methods: In 100 patients with SB, 6 muscles in the lower limbs were separately analysed. Due to the number of affected muscles, we evaluated 5 groups of patients: with 1 affected muscle, 2 affected muscles, 3 affected muscles, 4 affected muscles and 5 affected muscles. Three degrees of neurogenic lesions were assessed: mild, moderate and severe. Results: The tibialis anterior muscle was most frequently affected in SB patients. The outer anal sphincter was frequently affected in the group of SBA patients. Single muscle affection is frequent in the group of patients with SBO, while in the group of patients with SBA, 4 muscles were significantly frequently affected. The great majority of patients (45.46%) with affected outer anal sphincter (OAS) in the group of SBO were without affection of other muscles, while for the SBA group it was for every third patient. Mild neurogenic lesion was significantly frequent in SBO patients, while severe form was significantly frequent in SBA patients. Conclusions: Patients with SBO usually present with mild to moderate clinical presentation, while multiple root involvement and severe degree of neurogenic lesion is associated more frequently with SBA.
