Abstract
BACKGROUND Instrumented measurements of postural control provide a more accurate insight into the motor development of children with autism. This study aimed to identify postural control deficits in autistic children during quiet standing before and after transient locomotor task. It was hypothesized that the parameters that characterize the trajectory of center of foot pressure (COP) displacement would be higher in autistic children compared to typically developing children. METHODS Sixteen autistic children aged 6-10 but without a comorbidity diagnosis, were enrolled in the study group. The control group comprised 16 typically developing peers. The assessment of the transitional task comprised four different conditions: unperturbed and perturbed transition, stepping up, and stepping down tasks. Analysis of the COP signal was carried out for three distinct phases, i.e., phase 1 - quiet standing before step initiation, phase 2 - transit, and phase 3 - quiet standing until measurement completion. FINDINGS The two-way ANOVA with a 2 × 4 factorial design (group × testing condition) revealed a group effect on all posturographic variables in the antero-posterior and medio-lateral directions of phase 1 and in the antero-posterior direction of phase 3. The Bonferroni post-hoc test showed the means of all those variables were significantly higher for the autistic than for typically developing children. Group allocation also had an effect on the time of transit and step length, which turned out to be significantly longer in autistic children compared to healthy peers. INTERPRETATION Autistic children show increased postural sway before and after transitional locomotor tasks compared to typically developing children. The trial was prospectively registered in the Australian and New Zealand Clinical Trials Registry (no. ACTRN12621001113842; date registered: 23.08.2021).

Abstract
Stroke remains one of the greatest health challenges worldwide, due to a high mortality rate and, despite great progress in its treatment, the significant disability that it causes. Studies conducted around the world show that the diagnosis of stroke in children is often significantly delayed. Paediatric ischaemic arterial stroke (PAIS) is not only a problem that varies greatly in frequency compared to the adult population, it is also completely different in terms of its risk factors, clinical course and outcome. The main reason for the lack of a rapid diagnosis of PAIS is a lack of access to neuroimaging under general anaesthesia. The insufficient knowledge regarding PAIS in society as a whole is also of great importance. Parents and carers of children should always bear in mind that paediatric age is not a factor that excludes a diagnosis of stroke. The aim of this article was to develop recommendations for the management of children with acute neurological symptoms suspected of ischaemic stroke and further treatment after confirmation of the ischaemic aetiology of the problem. These recommendations are based on current global recommendations for the management of children with stroke, but our goal was also to match them as closely as possible to the needs and technical diagnostic and therapeutic possibilities encountered in Poland. Due to the multifactorial problem of stroke in children, not only paediatric neurologists but also a neurologist, a paediatric cardiologist, a paediatric haematologist and a radiologist took part in the preparation of these recommendations.

Abstract
BACKGROUND Proper postural and motor control plays a fundamental role in the child's ontogenetic development. So far, the postural control in children on the autism spectrum has mainly been assessed with standard posturographic measurements of center of pressure (COP) displacements. RESEARCH QUESTION What are the differences in postural control between autistic and typically developing children? METHODS The study group comprised 16 autistic children aged 6-10 years, identified by a psychiatrist. The control group consisted of 16 typically developing children aged 6-10 years with no posture deformities, no pervasive developmental disorder and no history of postural control or movement deficits. The data were collected during quiet standing with eyes open using a force plate. To gain a better insight into the postural control processes, the rambling-trembling and sample entropy analyses were used in COP data processing. RESULTS Compared to typically developing children, those with autism spectrum had significantly higher values of COP and rambling trajectory parameters in the antero-posterior direction during quiet standing. The variables of the trembling trajectory did not differ significantly between the groups. The autistic children had significantly lower values of sample entropy in the antero-posterior direction compared to typically developing children. SIGNIFICANCE More advanced measures of COP displacements including the rambling-trembling method and sample entropy revealed differences in postural control between autistic and typically developing children. These methods may therefore contribute to functional assessment of postural control deficits in children on the autism spectrum.

Abstract
BACKGROUND KIF1A (kinesin family member 1A)-related disorders encompass a variety of diseases. KIF1A variants are responsible for autosomal recessive and dominant spastic paraplegia 30 (SPG, OMIM610357), autosomal recessive hereditary sensory and autonomic neuropathy type 2 (HSN2C, OMIM614213), and autosomal dominant neurodegeneration and spasticity with or without cerebellar atrophy or cortical visual impairment (NESCAV syndrome), formerly named mental retardation type 9 (MRD9) (OMIM614255). KIF1A variants have also been occasionally linked with progressive encephalopathy with brain atrophy, progressive neurodegeneration, PEHO-like syndrome (progressive encephalopathy with edema, hypsarrhythmia, optic atrophy), and Rett-like syndrome. MATERIALS AND METHODS The first Polish patients with confirmed heterozygous pathogenic and potentially pathogenic KIF1A variants were analyzed. All the patients were of Caucasian origin. Five patients were females, and four were males (female-to-male ratio = 1.25). The age of onset of the disease ranged from 6 weeks to 2 years. RESULTS Exome sequencing identified three novel variants. Variant c.442G>A was described in the ClinVar database as likely pathogenic. The other two novel variants, c.609G>C; p.(Arg203Ser) and c.218T>G, p.(Val73Gly), were not recorded in ClinVar. CONCLUSIONS The authors underlined the difficulties in classifying particular syndromes due to non-specific and overlapping signs and symptoms, sometimes observed only temporarily.

Abstract
Background. Paediatric-onset MS (POMS) has a unique clinical profile compared to the more prevalent adult-onset MS. For this study, we aimed to determine the demographic and clinical characteristics of POMS in Poland as well as addressing some of its epidemiological aspects. Methods. A retrospective study was conducted based on the Polish Multiple Sclerosis Registry, considering a population of children and adolescents with MS (age ≤ 18 years). Data were collected by all 13 centres across Poland specializing in diagnosing and treating POMS. The actual course of the disease and its clinical properties were compared between child (≤12 years) and juvenile (>12 years) patients. MS onset and its prevalence were assessed at the end of 2019, stratified by age range. Results. A total of 329 paediatric or juvenile patients (228 girls, 101 boys) with a clinically definite diagnosis of MS, in conformity with the 2017 McDonald Criteria, were enrolled. For 71 children (21.6%), the first symptoms appeared before the age of 12. The female: male ratio increased with age, amounting to 1:1 in the ≤12 years group and to 2.9:1 in the >12 years group. In most cases, the disease had multi-symptomatic onset (31.3%), and its course was mostly of a relapsing−remitting character (95.7%). The initial Expanded Disability Status Score for both groups was 1.63 ± 1.1, whereas the annual relapse rate was 0.84 during the first 2 years. The time between the onset of symptoms and diagnosis was longer in the younger patients (8.2 ± 4.2 vs. 4.6 ± 3.6 months; p < 0.005). On 31 December 2019, the age-adjusted prevalence standardized to the European standard population was 5.19/100,000 (95% CI, 4.64−5.78). Significantly higher prevalence was noted in the 13−18 years group (7.12; 95% CI, 6.64−7.86) than in the 9−12 years group (3.41; 95% CI, 2.98−3.86) and the <9 years group (0.56; 95% CI, 0.46−0.64; p < 0.001). Conclusion. POMS commencing at the age of ≤12 years is rare, differing significantly from the juvenile-onset and adult MS in terms of clinical characteristics, course, and incidence, as stratified by gender.

Abstract
Eating disorders among children and youth are a serious social problem. The time of development is the starting point in shaping eating patterns. Proper nutrition provides the basis for psychophysical development. A knowledgeable pediatrician can improve society’s health by engaging parents and, later, the child or youth. We offer knowledge on the nutrition basics and the commonly available tools to assess the nutritional status. We will discuss the characteristics of eating and body mass disorders in developing children. We will provide information on the warning signals of eating and body mass disorders and recommend prophylaxis. The reader will be familiarized with the motivational dialogue as an effective control tool for the discussed health issues.

Abstract
Autism spectrum disorder (ASD) and cerebral palsy (CP) are some of the most common neurodevelopmental diseases. They have multifactorial origin, which means that each case may manifest differently from the others. In patients with ASD, symptoms associated with deficits in social communication and characteristic, repetitive types of behaviors or interests are predominant, while in patients with CP, motor disability is diagnosed with accompanying cognitive impairment of various degrees. In order to minimize their adverse effects, it is necessary to promptly diagnose and incorporate appropriate management, which can significantly improve patient quality of life. One of the therapeutic possibilities is stem cell therapy, already known from other branches of medicine, with high hopes for safe and effective treatment of these diseases. Undoubtedly, in the future we will have to face the challenges that will arise due to the still existing gaps in knowledge and the heterogeneity of this group of patients. The purpose of this systematic review is to summarize briefly the latest achievements and advances in stem cell therapy for ASD and CP.

Abstract
The aim of the study was to perform family-based association analysis of PRKCB1, CBLN1 and KCNMB4 gene polymorphisms and autism disorder. We comprised 206 Caucasian children with autistic spectrum disorder (ASD) and their biological parents. In transmission/disequilibrium test we observed that T-allele of the rs198198 polymorphism of the PRKCB1 gene was more often transmitted to affected children in the male subgroup (p = 0.010). Additionally, the T carrier state was significantly associated with hypotonia (p = 0.048). In the female subgroup, the T-allele carriers more often showed more mobile/vital behavior (p = 0.046). In conclusion, our study showed that the rs198198 of the PRKCB1 gene may be associated with ASD in men and with some features characteristic for the disorder.

Abstract
BACKGROUND ALG13-CDG belongs to the congenital disorders of glycosylation (CDG), which is an expanding group of multisystemic metabolic disorders caused by the N-linked, O-linked oligosaccharides, shared substrates, glycophosphatidylinositol (GPI) anchors, and dolichols pathways with high genetic heterogeneity. Thus, as far as clinical presentation, laboratory findings, and treatment are concerned, many questions are to be answered. Three individuals presented here may serve as a good example of clinical heterogeneity. This manuscript describes the first metabolomic analysis using NMR in three patients with epileptic encephalopathy due to the recurrent c.320A>G variant in ALG13, characterized to date only in about 60 individuals (mostly female). This is an important preliminary step in the understanding of the pathogenesis of the disease associated with this variant in the rare genetic condition. The disease is assumed to be a disorder of N-glycosylation given that this is the only known function of the ALG13 protein. Despite this, protein electrophoresis, which is abnormal in most conditions due to abnormalities in N-glycosylation, has been normal or only mildly abnormal in the ALG13 patients. METHODS Nuclear magnetic resonance (NMR) spectroscopy in conjunction with multivariate and univariate modelling were used to analyze the metabolic profile of the blood serum samples acquired from the studied patients. RESULTS Three metabolites were identified as potential biomarkers: betaine, N-acetyl-glycoprotein, and carnitine. CONCLUSIONS Since presented data are the first to be collected so far, they need be verified in further studies. Our intention was to turn attention toward possible CDG-ALG13 laboratory markers that would have clinical significance.

Abstract
AIM OF THE STUDY This study aimed to evaluate the effects of nusinersen therapy in Polish children with SMA type 1. CLINICAL RATIONALE OF STUDY Spinal muscular atrophy (SMA) is a neuromuscular disorder that is characterised by the loss of motor neurons, progressive muscle weakness and atrophy, leading to increased disability and mortality. Nusinersen, an antisense oligonucleotide that promotes production of the functional survival motor neuron protein is approved for the treatment of SMA 5q in the European Union. In 2017, an early access programme (EAP) for nusinersen was launched in Poland. In this study, we present the results of nusinersen treatment in Polish patients participating in the EAP. MATERIALS AND METHODS We collected prospectively clinical data including mutational analysis of SMN1 and SMN2 genes, motor function outcomes as measured on a standardized scales, ventilatory and nutritional status, on SMA type 1 patients receiving nusinersen in three EAP centres in Poland. Scores on the CHOP-INTEND scale after 18-26 months of treatment were compared to baseline. RESULTS We analysed data from 26 patients with SMA type 1, mean age 4.79 (2-15) years. The mutational analysis revealed two SMN2 gene copies in the majority of patients (61.54%). Three and four copies were found in 34.62% and 3.84%, respectively. Median disease duration was 21 months. Half (n = 13) of the patients required mechanical ventilation at baseline and 57.69% (n = 15) were fed by nasogastric tube or percutaneous endoscopic gastrostomy. No patient worsened during the follow-up. Mean improvement in CHOP-INTEND from baseline to the last follow-up was 7.38 points (p < 0.001). CHOP-INTEND scores did not decline for any patient. Patients with three or more SMN2 gene copies had higher scores than did the patients with two copies (p = 0.013), and they tended to show greater improvement over time, but the difference was not significant (p = 0.324). Shorter disease duration and higher CHOP-INTEND baseline score were associated with a better response (p = 0.015). Patients with a CHOP-INTEND score above the median had higher scores overall than the rest (p < 0.0013), and they improved significantly more than the rest (p = 0.037). Nusinersen was well tolerated, no new safety findings were identified. CONCLUSIONS AND CLINICAL IMPLICATIONS Our data indicates that nusinersen treatment might be effective in SMA type 1 patients, regardless of their age and functional status.

Abstract
BACKGROUND Preschool age is fundamental for the development of gross motor skills. Timely detection of postural stability deficits using objective methods would facilitate early implementation of therapeutic strategies. RESEARCH QUESTION What are the age- and gender-related differences in postural control between preschool children diagnosed with developmental delay in their first year of life and children with typical development? METHODS The study group consisted of 59 children diagnosed with developmental delay during infancy, who had received physiotherapy in the first year of their life for disorders of postural control and prone locomotion as well as abnormal distribution and magnitude of postural tone. The control group comprised 66 nursery school children with typical development and no history of postural control or movement deficits and no physiotherapy interventions in the first year of their life. The study and control groups were subdivided into four subgroups based on age (3-4 years, 5-6 years) and gender (boys, girls). The data were collected during quiet standing using a force plate. Three 30-second trials were recorded. Stabilographic recordings were analysed using the rambling-trembling approach. RESULTS Three-way ANOVA revealed a gender effect on all measured variables (p < 0.05). The Tukey HSD (honest significant difference) post-hoc test showed that some of the values of sway range and mean velocity of COP, rambling and trembling in sagittal and frontal plane were significantly greater in control boys aged 3-4 years compared to other subgroups (p < 0.05). SIGNIFICANCE Long-term postural control monitoring by a pediatrician and/or physiotherapist seems justified and not only in children with a history of infantile developmental delay but also in their healthy peers, especially boys.

Abstract
PURPOSE In the present study, the salivary melatonin secretion in the hypoxic ischemic encephalopathy (HIE) children was measured. The logit model was fitted to the data to obtain the salivary dim light melatonin onsets (DLMOs), and the results were compared with the values estimated from the classic threshold method with a linear interpolation and those previously published for the blood measurements. MATERIALS AND METHODS 9 patients suffering from HIE aged from 65 to 80 months were included in the study. The melatonin levels were assessed by a radioimmunoassay (RIA). The diurnal melatonin secretion was estimated using a nonlinear least squares method. Student's t-test and the Mann-Whitney U test were used for the comparisons of the obtained parameters. RESULTS The circadian profiles of the melatonin secretion for both calculation methods do not differ statistically. The DLMO parameters obtained in the blood and saliva samples in children with hypoxic ischemic encephalopathy were similar.

Abstract
OBJECTIVES The aims of the study were to assess the kinematics of the lower limbs and pelvis during normal walking in professional ballet dancers and to investigate relationships between movements of segments of the lower limbs and pelvis. METHODS Thirty one professional ballet dancers and twenty eight controls completed five walking trials at their preferred speed. Kinematic data in the basic anatomical planes for ankle, knee, and hip joints as well as for the pelvis were collected with an optoelectronic motion system. RESULTS The female ballet dancers had in comparison with the controls significantly larger (p < 0.01) knee flexion in the swing phase and hip abduction in the preswing phase. Compared to the control group, the male ballet dancers had significantly larger dorsiflexion in the final stance and the total pelvic tilt range of motion. The number of significant correlations between kinematic parameters was higher in the female ballet dancers. CONCLUSIONS It can be concluded that specific movement techniques and compensatory strategies used in ballet dance can alter relationships between movements of segments of the lower limbs during normal walking. The relationships between movements in the joints of the lower limbs and pelvis are stronger in women.

Abstract
The HNRNPH2-associated disease (mental retardation, X-linked, syndromic, Bain type [MRXSB, MIM #300986]) is caused by de novo mutations in the X-linked HNRNPH2 gene. MRXSB has been described in six female patients with dysmorphy, developmental delay, intellectual disability, autism, hypotonia and seizures. The reported HNRNPH2 mutations were clustered in the small domain encoding nuclear localization signal; in particular, the p.Arg206Trp was found in four independent de novo events. HNRNPH1 is a conserved autosomal paralogue of HNRNPH2 with a similar function in regulation of pre-mRNAs splicing but so far it has not been associated with human disease. We describe a boy with a disease similar to MRXSB in whom a novel de novo mutation c.616C>T (p.Arg206Trp) in HNRNPH1 was found (ie, the exact paralogue of the recurrent HNRNPH2 mutation). We propose that defective function of HNRNPH2 and HNRNPH1 nuclear localization signal has similar clinical consequences. An important difference between the two diseases is that the HNRNPH1-associated syndrome may occur in boys (as in the case of our proband) which is well explained by the autosomal (chr5q35.3) rather than X-linked localization of the HNRNPH2 gene.

Abstract
BACKGROUND Pediatric ischemic stroke is an important cause of morbidity and mortality. As previous studies of children after stroke showed, dyslipidemias were very common in Polish and other European populations. Thus, looking for genetic factors predisposing to pediatric stroke, its symptoms, and outcome, we have analyzed 2 polymorphisms of the upstream stimulating factor 1 (USF-1) gene. MATERIALS AND METHODS The study group consisted of 82 children with stroke, 156 parents, and 146 controls. We used 2 alternative methods: the case-control model and the analysis of families using the transmission disequilibrium test. The 2 polymorphisms, rs2516839 and rs3737787, were genotyped using the TaqMan Pre-Designed SNP Genotyping Assay. The Statistica 10.0 software was used in all statistical analyses. RESULTS We did not observe any statistical differences in genotype and allele frequencies between patients and controls. There were also no significant differences in the transmission of alleles from the parents to the affected children. However, we have observed that the TT genotype of the rs2516839 polymorphism was more common in patients with epilepsy and dysarthria, whereas the TT genotype of the rs3737787 polymorphism was more frequent in the group of patients with a decrease in intellectual functioning. CONCLUSIONS Our study did not show any associations between the 2 analyzed polymorphisms of the USF-1 gene and pediatric ischemic stroke. However, we have observed an influence of specific genotypes on the outcome of stroke, including epilepsy, dysarthria, and a decrease in intellectual functioning.

Abstract
The main aim of the study was to compare the melatonin rhythms in subjects with Angelman syndrome (n = 9) and in children with (n = 80) and without (n = 40) epilepsy (nonepileptic patients diagnosed with peripheral nerve palsies, myopathy, and back pain) using our mathematical model of melatonin circadian secretion. The characteristics describing the diurnal hormone secretion such as minimum melatonin concentration, release amplitude, phase shift of melatonin release, and sleep duration as well as the dim light melatonin onset (DLMO) of melatonin secretion and the γ shape parameter allow analyzing the fit and deducing about how much the measured melatonin profile differs from a physiological bell-shaped secretion. The estimated sleep duration and phase shift of melatonin release as well as the DMLO offsets at 25% and 50% relative thresholds are the key characteristic of Angelman syndrome children. As revealed from the γ shape parameter, the melatonin secretion profiles are disturbed in majority of the AG subjects revealing rather a triangular course instead of the bell-like one.

Abstract
BACKGROUND Early detection of movement deficits during step initiation will facilitate the selection of the optimal physiotherapy management strategy. The main aim of the study was to assess potential differences in step initiation between 5- and 6-year-old children with faulty posture who had been diagnosed with neurodevelopmental disorders during infancy and healthy children. METHODS The experimental group consisted of 19 children aged 5-6 years with faulty posture, who had been diagnosed with neurodevelopmental disorders during infancy and were given physiotherapy in the first year of their lives. The control group comprised 19 nursery school children aged 5-6 years with no postural defects, no history of postural control or movement deficits, and no physiotherapy interventions in the first year of their lives. Step initiation was performed on force platforms under various conditions, i.e., with and without an obstacle, stepping up onto a platform placed at a higher level, stepping down onto a platform placed on a lower level. The recording of center of foot pressure (COP) displacements was divided into three phases: phase 1 (P1)-quiet standing before step initiation, phase 2 (P2)-transit, phase 3 (P3)-quiet standing until measurement completion. RESULTS The Tukey post hoc test showed that the means of sway range (raCOP) and mean velocity (vCOP) in sagittal (AP) plane for phase 1 and vCOP in frontal (ML) plane for phase 3 registered in the step-up trial were significantly higher (p < 0.05) in children with faulty posture compared to children with typical development. P1vCOPML, P3vCOPAP, P3raCOPML, and P3vCOPMLof the step-down trial were also significantly higher in children with faulty posture (p < 0.05). CONCLUSION Inclusion of functional movement exercises (stair-walking tasks) in physiotherapy interventions for children with postural defects seems well justified.The trial was registered in the Australian and New Zealand Clinical Trials Registry (no. ACTRN12617001068358).

Abstract
BACKGROUND/PURPOSE Data on the role of the -455G > A polymorphism of the gene encoding β fibrinogen subunit (FGB) and the Thr312Ala polymorphism of the gene for the α fibrinogen subunit (FGA) in childhood ischemic stroke are insufficient. Therefore the aim of the study was to evaluate a possible association between these two polymorphisms and arterial ischemic stroke. METHODS The study group consisted of 85 children after ischemic stroke, 146 of their parents and 159 controls. Both polymorphisms were genotyped using the restriction fragment length polymorphism method. Two study designs were used: a case-control model and a family-based transmission-disequilibrium test. Statistica 7.1 and EpiInfo 6 softwares were used in all analyses. RESULTS In the TDT test, a tendency to a higher transmission of the 312Ala allele of the FGA gene and the -455A allele of the FGB gene was observed, however, it was statistically non-significant. The frequencies of alleles and genotypes of both FGA and FGB genes polymorphisms did not differentiate children from both groups also in the case-control model. Additive or synergistic effects between FGA and FGB genes polymorphisms were not observed. CONCLUSION An analysis of the results obtained in this study and a critical review of previously published data indicate that examined gene polymorphisms are not related to ischemic stroke in children.

Abstract
Moderate hyperhomocysteinemia is one of the risk factors of pediatric stroke. Methylenetetrahydrofolate reductase (MTHFR) is an important enzyme, which regulates homocysteine metabolism, and some polymorphisms of gene encoding this enzyme are associated with a decreased activity of the enzyme. The aim of the study was to assess an association between the A1298C polymorphism and pediatric stroke. We also evaluated a possible synergistic effect of A1298C and C677T polymorphisms of this gene. The study group consisted of 88 children after ischemic stroke, 142 of their parents and 111 controls. The A1298C polymorphism was genotyped using the restriction fragment length polymorphism method. We used 2 study designs: a case-control model and a family-based association test. The Statistica 7.1 and EpiInfo 6 softwares were used in all analyses. We did not observe any statistically significant differences either in the transmission of the A allele in the family-based test or in the frequency of the A allele in the patients group compared with the controls. We also did not notice any significant additive or synergistic effects between the A1298C and C677T polymorphisms. An analysis of the results obtained in this study and a critical review of previously published studies indicate that the A1298C polymorphism of the MTHFR gene is not related to ischemic stroke in children.

Abstract
Background The diagnosis of “drug resistance” in epilepsy can be defined and interpreted in various ways. This may be due to discrepant definitions of drug resistance to pharmacotherapy. The aim of our study was to investigate the relationship between C3435T polymorphism of the MDR1 gene and drug resistance in epilepsy with the consideration of 4 different criteria for qualification to groups sensitive and resistant to applied pharmacotherapy. Material/Methods Evaluation of C3435T polymorphism of MDR1/ABCB1 gene was conducted on a group of 82 white children and young adolescents up to 18 years old. While qualifying the patients to the group of sensitive or drug resistant, the following 4 definitions of drug resistance were applied: the ILAE’s, Appleton’s, Siddiqui’s, and Berg’s. Results A detailed analysis of genotypes of the MDR1 gene did not show any significant discrepancies between the groups of patients resistant and sensitive to antiepileptic drugs (AEDs) in 4 consecutive comparisons taking into consideration various criteria of sensitivity and resistance to pharmacotherapy. Conclusions The obtained results clearly confirm the lack of a connection between the occurrence of drug-resistant epilepsy and C435T polymorphism of the MDR1 gene irrespective of the definition of drug resistance applied to the patient.

Abstract
Somatoform disorders are often the main cause for seeking professional advice and performing a number of specialist checks. The aim of the study was to determine the frequency of somatoform disorders in the form of headaches in children and adolescents neurologically diagnosed and the risk factors thereof. Analysis of the biological and situational risk factors were established. Somatoform disorders were diagnosed in 27 out of 276 children with headaches. We concluded that in the differential diagnosis of headaches, somatoform headaches should not be omitted as every 10(th) patient in the developmental age diagnosed on the neurological ward because of headache shows signs of somatoform headaches. In diagnostically difficult cases it is recommended that analysis of biological and situational risk factors be performed with special attention paid to chronic disease of the patient and/or in his immediate family, the patient's psychological disorders and dysfunctional or low social status families. The creation of separate criteria for somatoform disorders of the developmental age should be considered.

Abstract
The 677C>T polymorphism within methylenetetrahydrofolate reductase (MTHFR) gene is related to an elevated level of homocysteine. Thus it may be considered as a genetic risk factor in ischemic stroke. Apparently studies of this type of polymorphism in childhood stroke have shown conflicting results. We performed meta-analysis of all the data that are available in relation with MTHFR polymorphism and the risk of ischemic stroke in children. We searched PubMed (last search dated December 2010) using "MTHFR polymorphism", "ischemic stroke" "child", "children", "pediatric stroke" as keywords and reference lists of studies and reviews on the topic. Finally, 15 case-control studies corresponded to the inclusion criteria for meta-analysis. These studies involved the total number of 822 children and adolescents after ischemic stroke and 1,552 control subjects. Fixed or random effects models were used depending on the heterogeneity between the studies. The association between ischemic stroke and 677C>T polymorphism within MTHFR gene was observed in three of the studies. The pooled analysis showed that TT genotype of MTHFR gene is more common in stroke patients than in controls (p = 0.0402, odds ratio = 1.57, 95 % confidence interval 1.02-2.41). The Egger's test did not reveal presence of a publication bias. The results based on a sizeable group of cases and controls have proved that the 677C>T polymorphism in MTHFR gene is associated with the development of ischemic stroke in children.

Abstract
OBJECTIVES Ischemic stroke remains one of the top ten causes of death in children. There is evidence for the role of pro-inflammatory cytokines, such as IL-6 and the -174G>C promoter polymorphism of the IL-6 gene, in the occurrence and outcome of stroke in adults. The aim of the present study was to determine a possible association between the -174G>C IL-6 polymorphism and occurrence of paediatric stroke, its symptoms and outcome. MATERIAL AND METHODS The study group consisted of 340 individuals: 80 stroke children, 122 parents of patients and 138 controls. The -174G/C polymorphism was genotyped using the RFLP method. For the analysis of the relationship between genotypes and stroke we used two alternative methods: the case-control model and the transmission test for linkage disequilibrium using data from families. RESULTS We observed no differences in the transmission of alleles from parents to children. We also did not find any statistical differences in distribution of genotypes and alleles between patients and controls. However, the analysis showed that post-stroke epilepsy was genotype-dependent. All children with epilepsy were G allele carriers and none of them was a CC homozygote whereas about 25% of children without epilepsy had the CC genotype. CONCLUSIONS Our study did not show any associations between the IL-6 -174 G>C polymorphism and the occurrence of stroke but we observed a relation between post-stroke epilepsy and the G allele carrier-state.

Abstract
Pediatric ischemic stroke, though relatively rare, remains an important medical problem since 20-40% of patients have recurrent strokes and 50-85% of them suffer from long-term neurological deficits. Approximately 20-50% of the affected children have prothrombotic disorders, therefore upon looking for possible genetic causes of the disease we focused on the plasminogen activator inhibitor (PAI-1)--the major inhibitor of fibrinolysis. The aim of the present study was to investigate a possible association between the -675_-674insG PAI-1 gene polymorphism and pediatric ischemic stroke. The study population consisted of 343 individuals: 70 children with ischemic stroke, 140 their biological parents and 133 control children. The PAI-1 gene polymorphism was genotyped using the restriction fragment length polymorphism and was visualized by AgNO₃ staining. The transmission/disequilibrium test showed exactly the same transmission of alleles from parents to the affected children (37:37). The case-control model also did not reveal any statistical significance in alleles and genotypes distribution between patients and control children. The obtained results suggest that the 4 G/5 G polymorphism of the PAI-I gene is not a risk factor of ischemic stroke in Polish children.

Abstract
Genes related to platelet and arterial endothelial function have been recently considered as independent risk factors for stroke. We aimed to analyze a relationship between the E-selectin 98G > T polymorphism and stroke in children and to observe the transmission of E-selectin alleles from heterozygous parents to their affected children. We studied 59 children after stroke, 112 parents, and 87 healthy children. The E-selectin 98G > T polymorphism was analyzed with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The frequency of the 98T allele in patients was almost twofold lower than in controls (5.1% vs. 9.8%, p = 0.145, odds ratios (OR) = 0.49) as well as carriers of the 98T allele (19.5% in controls vs. 8.5% in cases, p = 0.067, OR = 0.38). The G allele of the E-selectin 98G > T polymorphism was more frequently transmitted to the children after stroke compared to the T allele (68% vs. 32%). In conclusion, we did not confirm the relationship between the 98G > T polymorphism of the E-selectin gene and childhood ischemic stroke. There is still a need for further studies.

Abstract
Ischemic stroke in children is relatively rare, but it remains an important medical problem. Previous studies on Polish children have implicated dyslipidemias as significant risk factors in stroke. To search for genetic factors associated with the disease, the possible association between apolipoprotein E gene epsilon polymorphism and childhood stroke was evaluated. The study population consisted of 243 individuals: 72 children with ischemic stroke and 100 of their biological parents and 71 children without any symptoms of stroke. The apolipoprotein E gene epsilon polymorphism was genotyped using restriction fragment length polymorphism methodology. To analyze the possible association between this polymorphism and stroke, the transmission disequilibrium test and the case-control model were used. No preferential distribution of any allele from parents to the affected children was observed. There were also no significant differences in genotype and allele distribution between patients and control subjects. Study findings did not confirm that epsilon polymorphism of the apolipoprotein E gene is a risk factor of ischemic stroke in children.

Abstract
INTRODUCTION The ischemic stroke is a rare problem in childhood. Cardiac problems, arteriopathy, coaguopathies or dyslipidemia are traditional risk factors for stroke. The aim of the present study was to assess the relations between levels of lipids and fibrinogen and stroke among Polish children. MATERIAL AND METHODS We studied 75 patients (mean age: 8.24 +/- 5.56) and 71 healthy children (mean age: 10.32 +/- 5.7). The diagnosis of ischemic stroke was established with the WHO definition. RESULTS Serum triacylglycerols level and plasma fibrinogen level may be considered as risk factors for childhood stroke (p=0.004, OR=7.01 and p=0.024, OR=2.16, respectively). In the subgroup of stroke children with cardiac problems the triacylglycerols level is also the risk factor for stroke (p=0.006, OR=7.14). CONCLUSIONS Levels of triacylglycerols and fibrinogen again differentiated the subgroup of children with neurological deficits from controls. In conclusion, the levels of triacylglycerols and fibrinogen are important risk factors in the etiology of stroke.

Abstract
Ischemic stroke is a very rare and multifactorial disease in children. The aim of the study was to analyze the relationship between the methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism and stroke in Polish children and to observe whether there is any significant transmission of MTHFR alleles from heterozygous parents to their affected offspring. We analyzed 64 patients with stroke, 122 parents, and 59 healthy children. The MTHFR polymorphism was genotyped using polymerase chain reaction (PCR)-restriction fragment length polymorphism. The T allele was more frequent in the stroke group (38%) than in controls (25%, P = .029, odds ratio = 1.84). We also found higher frequency of T allele in male patients compared to male controls (46% vs. 25%, P = .009, odds ratio = 2.53). The number of T allele carriers was again more prevalent in boys with stroke (71%) than in healthy boys (45%, P = .023, odds ratio = 3.09). The T allele was significantly transmitted in male patients (P < .019). We conclude that the MTHFR 677C>T polymorphism may be considered as a genetic risk factor of childhood stroke, especially in boys.

Abstract
Cerebral cortical development can be divided into three steps: cellular proliferation, neuronal migration and organization. Based on known pathologic, genetic and neuroimaging features a classification for malformations of cortical development was proposed by Barkovich in 2001, and updated in 2005. Malformations of cerebral cortex development (MCCD) often demonstrate epileptic seizures and delay in psychomotor development. About 20-40% of children with epilepsy are drug-resistant and there is a large paediatric population requiring epilepsy surgery operations. In our work we performed clinical analysis of 68 children with MCCD treated in our hospital between 2000 and 2006. In our work to consider the type of MCCD we used the updated classification scheme proposed by Barkovich et al. We analyzed epilepsy, gestational and perinatal history, initial symptoms, time to establishing full diagnosis and neurodevelopmental/IQ status. In our results we found that despite similar clinical manifestation neuropathological basis could be significantly different, and vice versa: children with nearly identical neuropathological findings could have completely different neurological and radiological symptoms. Children with drug-resistant epilepsy are potential candidates for neurosurgical treatment; especially lesionectomies in such cases could be very promising in terms of epilepsy management and quality of life as well.

Abstract
PURPOSE The aim of this study is to find the relationship between visual function changes and vigabatrin treatment continuation or discontinuation. MATERIAL AND METHODS 19 patients (11 males, 8 females) from 8 to 20 years old, treated with vigabatrin because of partial epilepsy, were examined. Best corrected visual acuity, contrast sensitivity and static visual field were done. The examinations were repeated after 1-2 months and after 1-2 years. The longest follow-up was about three years (one girl). In some children from this group additional elctrophysiologic tests (ERG, EOG according to ISCEV standards), were done. RESULTS Corrected visual acuity was 5/5 in all eyes. Contrast sensitivity was normal and it was not changed in follow-up period. Abnormal visual field was found in more than half of examined patients. The improvement of visual field occurred after vigabatrin discontinuation, but in one patient the improvement occurred although vigabatrin treatment was continued. Most of the patients refused control ERG and EOG, but in first examination decreased or border b-wave amplitude after "flicker 30Hz" was found. CONCLUSIONS In some patients treated with vigabatrin reversible visual field changes occurred. Multicentre study should be performed, to solve the problem of relationship between visual field changes, vigabatrin and other antiepileptic treatment. All tests in group of epileptic patients are difficult because of poor cooperation.

Abstract
Nonepileptic seizures of psychogenic origin (NESP) belong currently to dissociation disorders. Their causes and precise outline of diagnostics, therapy and prophylaxis procedures remains still difficult. The authors investigated the group that consisted of 25 patients with the above described type of seizures. Prospective examinations were conducted. In each patient detailed analysis of risk factors and clinical semiology before and after hospital admission was performed. Moreover brain MRI, psychological and psychiatric examinations were made. Among patients with NESP, girls prevailed (88%). Most important stressogenic factor was trouble with peer relationships. Clinical manifestation was diverse, mostly the attacks were similar to epileptic, simple, partial seizures. The final diagnosis depended on results of video examinations (lack of clinical-bioelectrical correlation or lack of bioelectrical activity disturbances before or after attack) and results of psychological and psychiatric consultation.

Abstract
Tuberculosis of the central nervous system possess a serious clinical and radiological problem, since early treatment of this condition is crucial for the patient's life, and tuberculous process in the CNS may mimic many other pathologies. In this paper three cases of tuberculous process difficult to diagnose are presented. In all the cases early treatment could be started due to MRI findings suggesting tuberculous etiology. The authors emphasize the importance of presumptive radiological diagnosis in reducing the morbidity and mortality rates due to CNS tuberculosis.

Abstract
BACKGROUND This article reports the results of research into the activities of lactic acid concentrations in the body fluids of children with progressive encephalopathies (PE) in comparison to patients with non-progressive encephalopathies (NPE) and those with non-progressive encephalopathies with concomitant epilepsy (NPEE). The study was designed to determine whether there is difference between the serum and CSF lactic acid concentrations in children with progressive encephalopathies (PE), static (non-progressive) encephalopathies (NPE) and non progressive encephalopathies with concomitant epilepsy (NPEE), and whether the clinical status correlates with the concentration of these biochemical markers in children with PE. MATERIAL/METHODS The assessment involved 138 children of both sexes, whose age ranged between 8 months and 15 years, diagnosed and treated in the Neurology Department at the Pediatric Clinic of the Silesian Medical Academy in Katowice between 1995 and 1997. Lactate concentrations were determined in serum and cerebro-spinal fluid and analyzed statistically. RESULTS The findings showed higher serum and CSF concentrations in children with PE than in patients who manifested non-progressive forms of encephalopathy. The degree of clinical symptom aggravation in PE children was likewise analyzed and compared to the values of lactate concentrations in body fluids; however, no correlation was found between these parameters. CONCLUSIONS Children with progressive encephalopathies present higher lactate concentrations in serum and cerebrospinal fluid than patients with static (non-progressive) encephalopathy.

Abstract
One of the leading positions on the world's list of harmful substances is taken by cadmium, which is a heavy metal. Cadmium (Cd) gets into the human body through either respiratory tract (cigarette smoke) or alimentary canal. The aim of the study was to 1) determine whether the concentrations of cadmium in blood and urine of children from Katowice Murcki--one of the cleanest districts of the town - as well as its contents in the hair of the children exceeds acceptable values and 2) to analyse the effect of chosen environmental factors (exposition to smoke, parents' education) on the amount of cadmium in these materials. The study comprised 48 children at the age from 9-11 years from Katowice Murcki, attending the same primary school. The findings were statistically analysed using Shapiro-Wilk and Wilcoxon test. Concentration of cadmium in the blood was 0.479 microg/l, in urine 0.840 microg/g creatinine and the average concentration in the hair constituted 0.23 microg/g drymass. Concentration of cadmium in the blood of 13 children (30.95%) exceeded acceptable 0.5 microg/l value, while in 10 children (23.25%) value in the urine was exceeded. It was lug/g creatinine. It has been shown that children who lived nearby motorway presented higher content of cadmium in the hair. Environmental factors such as: location of the road and intensity of traffic influence the content of cadmium in the human body.

Abstract
Brain malformations are important and frequent epilepsy reason in children and adolescents. During the last six years in neurological department of Pediatrics Clinic in Katowice were treated 106 children with brain malformations demonstrated in magnetic resonanse imaging. The main clinical symptoms in these patients were following: mental retardation, epilepsy, abnormalities in neurological examinations, dysmorphic features. Epilepsy were observed in above 3/4 of patients (84 children). In most of them there was intractable epilepsy (55 children). The aim of study was evaluation of selected factors in prognosis of epilepsy intractibility. The children with brain malformations and epilepsy were divided into two groups: with intractable epilepsy and with good response for pharmacotherapy. The type of malformation, the pre- i perinatal history, an age at which the first seizures appeared, abnormalities in neurological examination and IQ were compared in both groups. The differences weren't significant statistically apart two data. Normal pre- and perinatal history and early manifestation of seizures (during the first half of life) were confirmed significant statistically more often in group of patients with intractable epilepsy. There was limited value of most of the analysed parameters in prognosis of epilepsy intractibility. Further accumulating of data and increasing of number of the patients group with different types of malformations as well as progress in diagnostics, particularly molecular genetics, may be helpful in correct prognosis.

Abstract
Analysis of 102 Polish Duchenne/Becker muscular dystrophy (D/BMD) patients was performed by 'multiplex' amplification of 22 fragments of the DMD/BMD gene and deletions were found in 55% of the patients. The data obtained using PCR were compared with results of 25 Southern blotting and hybridization experiments with cDNA probes and with immunostaining using anti-dystrophin antibodies. In order to determine more precise deletion breakpoints, additional experiments were performed on dystrophin transcripts isolated from peripheral blood lymphocytes. These data found direct application in carrier analysis in the respective families by detection or exclusion of aberrant cDNA fragments. Carrier detection was also performed by RFLP-PCR, analysis of polymorphic (CA)n repeats and single stranded conformational polymorphism (SSCP) for selected exons of the DMD gene.
