Return to Work after Primary Total Knee Arthroplasty: The First Polish Pilot Retrospective Study.

(1) Background: Total knee arthroplasty (TKA) performed on working-age patients significantly affects the participation of such patients in social life. A retrospective study was conducted to determine the return to work (RTW) rate after TKA. The goal of this study was to provide reference data for the Polish population and identify the factors impacting patients' decisions to return to or resign from work, relative to their functional performance. (2) Methods: This retrospective study involved 48 patients. An interview related to RTW was carried out to identify the factors impacting a patient's decision to return to or resign from work. Functional performance was assessed using the Knee Outcome Survey-Activities of Daily Living (KOS-ADL) scale. (3) Results: Before TKA, 15 individuals (31.25%) qualified for the study did not work and were receiving welfare benefits. After the surgery, 23 individuals (47.9% of those working prior to TKA) did not return to work. The number of those who did not work after TKA increased to 38 (79.17%), which was a significant change. The mean level of functional performance after TKA assessed using KOS-ADL was 75.89. (4) Conclusions: The findings show that the rate of RTW after TKA in Poland is significantly lower than that in other countries. The reasons for this situation, as shown in the study, may be related to the lack of an occupational rehabilitation system, resulting in a paucity of information about the possibility to return to work and about opportunities for retraining.

Impact of the COVID-19 Pandemic on the Level of Anxiety and Depression in Caregivers of Children Benefiting from Neurorehabilitation Services.

INTRODUCTION: At the turn of March and April 2020, due to the occurrence of COVID-19 in Poland, the first restrictions on the provision of rehabilitation services were introduced. Nevertheless, caregivers strived to ensure that their children could benefit from rehabilitation services. AIM OF THE STUDY: To determine which of the selected data presented in the media reflecting the intensity of the COVID-19 epidemic in Poland differentiated the level of anxiety and depression in caregivers of children benefiting from neurorehabilitation services. MATERIAL AND METHODS: The study group consisted of caregivers of children (n = 454) receiving various neurorehabilitation services in the inpatient ward of Neurological Rehabilitation of Children and Adolescents (n = 200, 44%), in the Neurorehabilitation Day Ward (n = 168, 37%), and in the Outpatient Clinic (n = 86, 19%) of the Clinical Regional Rehabilitation and Education Center in Rzeszow. The average age of the respondents was 37.23 ± 7.14 years. The Hospital Anxiety and Depression Scale (HADS) was used to measure the severity of anxiety and depression in caregivers of children. The questionnaires were distributed from June 2020 to April 2021. As a measure of the severity of the COVID-19 epidemic in Poland, the figures presented in the media were adopted. In addition, data on the COVID-19 pandemic presented in the media (Wikipedia, TVP Info, Polsat Nes, Radio Zet) on the day preceding the completion of the survey were analyzed based on statistical analysis methods. RESULTS: 73 of the surveyed caregivers (16.08%) suffered from severe anxiety disorders, and 21 (4.63%) from severe depressive disorders. The average severity of anxiety (HADS) in the subjects was 6.37 points, and the average severity of depression was 4.09 points. There was no statistically significant relationship between the data presented in the media-such as daily number of infections, total number of infections, daily number of deaths, total number of deaths, total number of recoveries, number of hospitalizations, and people under quarantine-and the level of anxiety and depression of the studied caregivers (p > 0.05). CONCLUSIONS: It was not found that the selected data presented in the media, showing the intensity of the COVID-19 epidemic in Poland, significantly differentiated the level of anxiety and depression among caregivers of children using neurorehabilitation services. Their motivation to continue the treatment, caused by concern for their children's health, resulted in less severe symptoms of anxiety and depression during the peak period of the COVID-19 pandemic.

The Influence of Family Crisis Coping Strategies on Family Quality of Life in the Assessment of Patients with Idiopathic Scoliosis.

The aim of the study was to assess the impact of the strategies of coping with the family crisis in children and adolescents with idiopathic scoliosis on the level of their family's quality of life (FQOL). The study group consisted of 100 adolescents (girls 83%, boys 17% of the entire main group) with an average age of 14 (13.83 ± 1.92). The control group consisted of the same number of people as the study group (girls 78%, boys 22% of the entire control group) with an average age of 14 (14.09 ± 2.16). The FQOL scale was used to assess the family's quality of life, and the F-COPES scale was used to assess the problem-solving strategies used by the family (individual members) in a difficult life situation. Statistical analysis showed significant differences between the two compared groups. While dealing with a crisis situation in their families, adolescents treated for idiopathic scoliosis were using the spiritual support strategy (M ± SD 5.12 ± 2.07) significantly more often, while their healthy peers much more willingly and more often benefited from other possible strategies (F-COPES). Additionally, statistically significant differences were observed in the assessment of children and adolescents from both groups that the usage of different strategies available on the F-COPES scale correlated and affected the areas of the FQOL level of their families. Gaining spiritual support had a negative impact on the area of physical and financial well-being of FQOL, as assessed by juveniles with SI (R = -0.254, p = 0.011). However, in the opinion of healthy peers, the strategy of gaining social support (F-COPES) resulted in a higher level of FQOL in the area of disability problems (p = 0.005). A long process of SI treatment can cause crisis situations for patients and their families and affect both the physical and mental health of patients by changing the FQOL level of their families.

Impact of mild COVID-19 on balance function in young adults, a prospective observational study.

Balance is of essential importance in human life. The aim of the study is to examine the incidence of balance impairments in young adults who have recovered from mild COVID-19. The study involved 100 subjects, divided into two groups: the study group (50 individuals) comprised subjects who had recovered from mild COVID-19, and the control group (50 individuals) consisted of healthy subjects matched for gender and age. Balance was assessed using a force platform and clinical tests such as: timed up and go test, 15-s step test, sit-to-stand test and 6-min walk test. The assessment on the platform showed greater balance impairments in the trials with eyes closed; more specifically, compared to the controls, in trials with double-leg support the subjects from the study group acquired significantly higher scores in X average (lateral coordinates) (p < 0.05), Path length, V average (average Centre of Foot Pressure Velocity) (p < 0.05) and Area circular (p < 0.01), with even more significant results in trials with single-leg support in X average (p < 0.001), Y average (anterior-posterior coordinates) (p < 0.001) and Path length (p = 0.004). Higher scores in the timed up and go test were found in the study group (p = 0.013). The control group had higher scores in the remaining tests. The current findings show that mild COVID-19 may lead to balance impairments in young adults. Statistically significant differences in balance were found between the subjects in the study group and the healthy controls. Further studies in this area should take into account more age groups, and patients recovered from severe COVID-19, and should investigate long-term consequences of COVID-19 reflected by balance problems.

Selected Correlates of Attitudes towards Rape Victims among Polish Medical Students.

Sexual violence against women, including rape, is a serious public health issue in many countries. Rape victims often meet health professionals in medical institutions for a range of health problems. The aim of this research was investigation of attitudes towards rape victims among medical students. METHODS: The study sample consisted of 1183 university students who represented various medical disciplines. The average age of the respondents was 23.3 years. The Attitudes toward Rape Victims Scale (ARVS) was used in this study. RESULTS: Higher scores in men indicate that they held less sympathetic attitudes towards rape victims than women (61.6 vs. 52.6, p = 0.0000). Given the univariate interaction, social environment, and religious commitment did not significantly differentiate the respondents in this respect. Students of the medical faculty obtained the lowest results (medicine 49.7 vs. midwifery and nursing: 54.1, other fields: 54.4, p = 0.0008), showing much understanding and empathy for rape victims. CONCLUSIONS: The surveyed medical students presented moderately positive attitudes towards rape victims, among them men somewhat negative than women who made more pro-victim judgments. Among all medical field of study, medicine was distinguished by higher empathy. Religion and social environment independently do not differentiate respondents in this respect.

Somatic Development Disorders in Children and Adolescents Affected by Syndromes and Diseases Associated with Neurodysfunction and Hydrocephalus Treated/Untreated Surgically.

Background: This study was conducted to evaluate the co-occurrence of hydrocephalus treated/untreated surgically and congenital nervous system disorders or neurological syndromes with symptoms visible since childhood, and with somatic development disorders, based on significant data obtained during admission to a neurological rehabilitation unit for children and adolescents. Methods: The study applied a retrospective analysis of data collected during hospitalization of 327 children and adolescents, aged 4−18 years, all presenting congenital disorders of the nervous system and/or neurological syndromes associated with at least one neurodysfunction that existed from early childhood. To allow the identification of individuals with somatic development disorders in the group of children and adolescents with hydrocephalus treated/untreated surgically, the adopted criteria considered the z-score values for body height, body weight, head circumference, body mass index, and head circumference index. Results: Treated/untreated hydrocephalus was observed in the study group at the rates of 8% and 0.9%, respectively. Among 239 patients with cerebral palsy, 9 (3.8%) had surgically treated hydrocephalus, 17 (70.8%) of 24 patients with neural tube defects also had hydrocephalus treated with surgery, and 3 (12.5%) of 24 patients with neural tube defects had untreated hydrocephalus. This medical condition was a more frequent comorbidity in subjects with neural tube defects compared with those with cerebral palsy (p < 0.001). Subjects with untreated hydrocephalus most frequently presented macrocephaly (p < 0.001), including absolute macrocephaly (p = 0.001), and with tall stature (p = 0.007). Excessive body mass co-occurred more frequently with surgically untreated hydrocephalus, but the relationship was not statistically significant (p = 0.098). Conclusions: Surgically treated hydrocephalus occurred in patients with cerebral palsy and neural tube defects, and untreated hydrocephalus was present only in patients with neural tube defects. Untreated hydrocephalus negatively changed the course of individual development in the studied group of children, in contrast to surgically treated hydrocephalus.

Selected factors determining the failure to undertake physical activity in patients with multiple sclerosis in Poland.

Background: The main aim of the study was to identify selected factors that determine patients with multiple sclerosis (MS') failure to take home therapeutic exercises (HTE) and other physical activity (OPA). Materials and Methods: The study was conducted using a self-completed online survey that was aimed at adult people diagnosed with MS, registered on the portal TacyJakJa.pl. In total, 335 persons were involved. Results: Almost half of all people who completed the survey (49.9%), reported that no one encouraged them to use HTE, and only 16.1% were encouraged by their doctor. As many as 51% of the respondents reported also that no one encouraged them to undertake OPA, and only 18.5% were encouraged by their doctor. As the most important reason for not using HTE, the respondents chose fear that exercises may worsen their condition (47.3%). However, the most important reason for not using the OPA was high fatigue (61.9%). The number of people exercising at home increased with age (P = 0.013). Those surveyed with relapsing-remitting MS significantly more often (P = 0.002) took up OPA (60.7%) than the respondents with a secondary progressive MS (10.0%) and a primary progressive (4.4%). Conclusion: Physicians relatively rarely encourage patients with MS to undertake HTE and OPA. The patients do not perform HTE primarily because of fears of health deterioration or fatigue. Undertaking HTE is influenced by age but undertaking other forms of physical activity by the type of MS. Actions should be taken to popularize HTE and OPA, especially HTE among young patients.

Psychopathic personality disorder and cybercriminality: an outline of the issue.

The rapid development of information and communication technologies has created a new dimension in interpersonal relationships, which is commonly called cyberspace. Structural features of cyberspace such as anonymity, the lack of non-verbal indicators of interaction, their asynchrony, a sense of impunity and the lack of specific norms of conduct cause that the behavior of some people online may differ significantly from their behavior in real life. Individuals with psychopathic personality disorder can use cyberspace for criminal activities such as cyberbullying, trolling, digital piracy, cybervandalism or data theft. This is a very significant problem, as some researchers predict that as digital communication develops, 'cyberpsychopaths' will become the dominant form of criminals. Currently, there is a lack of research on the relationship between the structural features of cyberspace and the expression of psychopathic personality traits and their role in committing cybercrimes.

Psychological responses and associated factors during the initial stage of the coronavirus disease (COVID-19) epidemic among the adult population in Poland - a cross-sectional study.

INTRODUCTION: The study aimed to assess the emotional state, the occurrence of symptoms of depression, anxiety, and stress, as well as the quality of life of adults living in Poland during the first weeks of the COVID-19 pandemic. METHOD: The study was conducted on a group of 700 people aged 18 and over living in Poland. An anonymous online questionnaire was used in this cross-sectional study. The psychological impact of COVID-19 was measured using the Revised Event Impact Scale (IES-R) and the Depression, Anxiety, and Stress Scale (DASS - 21). The quality of life was assessed using the WHOQOL-BREF. RESULTS: In Poland, a high average level of post-traumatic stress was found as a result of the COVID-19 pandemic, with at least the minimum level occurring in all surveyed people. There was also a high incidence of depression (48.00%), anxiety (39.29%), and stress (54.86) in the first phase of the pandemic. The average level of quality of life in Poland was the lowest for the physical domain and amounted to 49.56 (SD = 11.71). The standard of living in the psychological domain was 60.26 (SD = 13.14). CONCLUSIONS: The pandemic is having a significant impact on human mental health. The very high average levels of post-traumatic stress, stress, anxiety, and depression as well as low quality of life make it necessary to consider interventions that will favor the use of more adaptive defense mechanisms and build mental resilience during an infectious disease pandemic and its long-term consequences.

Establishing the Minimal Clinically Important Differences for Sagittal Hip Range of Motion in Chronic Stroke Patients.

Many researchers have pointed out that decreased sagittal range of motion (ROM) in the affected hip joint is a common consequence of stroke, and it adversely affects walking performance and walking speed. Nevertheless, the minimal clinically important differences (MCID) in hip-related kinematic gait parameters post-stroke have not yet been determined. The present study aimed to define MCID values for hip ROM in the sagittal plane i.e., flexion-extension (FE), for the affected and unaffected sides at a chronic stage post-stroke. Fifty participants with hemiparesis due to stroke were enrolled for the study. Four statistical methods were used to calculate MCID. According to the anchor-based approach, the mean change in hip FE ROM achieved by the MCID group on the affected/unaffected side amounted to 5.81°/2.86° (the first MCID estimate). The distribution-based analyses established that the standard error of measurement in the no-change group amounted to 1.56°/1.04° (the second MCID estimate). Measurements based on the third method established that a change of 4.09°/0.61° in the hip ROM corresponded to a 1.85-point change in the Barthel Index. The optimum cutoff value, based on ROC curve analysis, corresponded to 2.9/2.6° of change in the hip sagittal ROM for the affected/unaffected side (the fourth MCID estimate). To our knowledge, this is the first study to use a comprehensive set of statistical methods to determine the MCID for hip sagittal ROM for the affected and unaffected sides at a chronic stage post-stroke. According to our findings, the MCID of the hip FE ROM for the affected side amounts to 5.81° and for the unaffected side to 2.86°, in patients with chronic stroke. This indicator is extremely important because it allows clinical practitioners to assess the effects of interventions administered to patients, and to interpret the significance of improvements in sagittal kinematic parameters of the hip; ultimately, it may facilitate the process of designing effective gait reeducation programs.

Knowledge and Attitudes of Young Adults Towards Donation of COVID-19 Convalescent Plasma and Its Therapeutic Properties.

PURPOSE: The aim of this study is to investigate the level of knowledge of the young adults towards the possible use of the convalescent plasma (CP) in the treatment of COVID-19 infection and their attitudes towards its donation. METHODS: Cross-sectional questionnaire was administered online to 1058 university students, representing 4 different colleges. The questionnaire included demographic data and 20 questions related to the knowledge and attitudes of respondents about possible use of the convalescent plasma in the treatment of COVID-19 infection and its donation. Comparative analyses were made using the Mann-Whitney and Kruskal-Wallis tests and the Spearman correlation coefficient. RESULTS: Significant relationships were found between dependent variables (level of knowledge and intensity of attitude) and gender, age, and student's college affiliation. There was no statistically significant correlation between dependent variables and respondents' social background and religious commitment. Studied young adults show a satisfactory knowledge relating to the therapeutic and preventive properties of the COVID-19 convalescent plasma. They also express a sufficient intensity of positive attitude towards CP donation. CONCLUSION: This study confirms the need for appropriate health promotional campaigns and educational programs aimed at popularization of CP donation in the general public, which would increase the chances of involving more patients recovered from COVID-19 disease.

Hyperbaric Oxygen Therapy for Children and Youth with Autism Spectrum Disorder: A Review.

Autism spectrum disorder (ASD) is a common neurodevelopmental disorder determined by a complex of factors (genetic and environmental). On a pathophysiological basis hyperbaric oxygen therapy (HBOT) has been suggested as an effective therapeutic method in ASD, and thus many parents/guardians attempt to treat their child with ASD using this method. Therefore, this review aimed to verify the significant therapeutic value of this method for individuals with ASD. The literature review included all articles from the last 5 years (2015-2021) that met the inclusion criteria-both original papers and literature reviews. None of the 10 literature reviews indicated that HBOT was a clearly effective form of therapy in the case of ASD. Two out of four papers presenting the results of the intervention studies also did not recommend the use of this form of therapy in children with ASD. The results of the other two studies were not entirely relevant to the purpose of this review because one study had no control group, while the other study focused solely on auditory processing disorders. A review of the literature on whether HBOT as a therapy significantly affects the symptoms of ASD does not confirm its effectiveness.

Nutritional Disorders in a Group of Children and Adolescents with Syndromes or Diseases Involving Neurodysfunction.

A study of the literature shows the lack of data on a comprehensive analysis of eating disorders in children with neurodysfunction, which constitute a clinical subgroup with an increased risk of abnormalities in this area. Therefore, the aim of this study was to determine the relationship between the coexistence of nutritional disorders and diseases or syndromes associated with neurodysfunction based on data collected during hospitalization at a rehabilitation center for children and adolescents. A retrospective analysis was carried out in a group of 327 children and adolescents aged 4-18 years. The study group covered various types of diseases or syndromes involving damage to the central nervous system. A retrospective analysis of baseline data (age, sex, main and additional diagnosis and Body Mass Index-BMI) was performed. Two assessment criteria of nutritional status were taken into account (z-score BMI and other previously published normative values). In the study group, malnutrition was found more frequently (18.0% of the respondents) than obesity (11.3% of the subjects). Hypothyroidism coexisting with malnutrition was identified in the study group (N% = 43.8%, p = 0.011) and malnutrition with tetraplegia in the subgroup of spastic cerebral palsy (N% = 34.2 %, p = 0.029).

Microsomic and macrosomic body structure in children and adolescents affected by syndromes or diseases associated with neurodysfunction.

In Poland the issue of microsomic body structure (micro-SBS) and macrosomic body structure (macro-SBS) has so far been overlooked. Up until now only a small amount of data have been published, most often as an overview of the problem. The current study was designed to investigate the co-occurrence of microsomic/macrosomic body structure (micro/macro-SBS) and congenital nervous system disorders or neurological syndromes with symptoms visible from infancy, based on essential data acquired during admission procedures at a neurological rehabilitation ward for children and adolescents. The study applied a retrospective analysis of data collected during hospitalization of 327 children and adolescents, aged 4-18 years who had been affected since infancy by congenital disorders of the nervous system and/or neurological syndromes associated with a minimum of one neurodysfunction. To identify subjects with microsomic or macrosomic body structure in the group of children and adolescents, the adopted criteria took into account z-score values for body height (z-score Ht), body weight (z-score Wt), head circumference (z-score HC), BMI (z-score BMI) and head circumference index (z-score HCI). The rates of micro/macro-SBS in the study group amounted to 7.3% and 0.6%, respectively. The findings show a more frequent co-occurrence of, as well as statistically significant correlations between, micro/macro-SBS and type of spasticity (cerebral palsy) (p = 0.024) as well as hydrocephalus not treated surgically (p < 0.001). Macro-SBS was found to more frequently co-occur with hemiplegia and hydrocephalus not treated surgically.

Abnormal cranium development in children and adolescents affected by syndromes or diseases associated with neurodysfunction.

Microcephaly and macrocephaly can be considered both cranial growth defects and clinical symptoms. There are two assessment criteria: one applied in dysmorphology and another conventionally used in clinical practice. The determination of which definition or under which paradigm the terminology should be applied can vary on a daily basis and from case to case as necessity dictates, as can defining the relationship between microcephaly or macrocephaly and syndromes or diseases associated with neurodysfunction. Thus, there is a need for standardization of the definition of microcephaly and macrocephaly. This study was designed to investigate associations between abnormal cranial development (head size) and diseases or syndromes linked to neurodysfunction based on essential data collected upon admission of patients to the Neurological Rehabilitation Ward for Children and Adolescents in Poland. The retrospective analysis involved 327 children and adolescents with medical conditions associated with neurodysfunction. Two assessment criteria were applied to identify subgroups of patients with microcephaly, normal head size, and macrocephaly: one system commonly used in clinical practice and another applied in dysmorphology. Based on the results, children and adolescents with syndromes or diseases associated with neurodysfunction present abnormal cranial development (head size), and microcephaly rarely co-occurs with neuromuscular disease. Macrocephaly frequently co-occurs with neural tube defects or neuromuscular diseases and rarely with cerebral palsy (p < 0.05); microcephaly frequently co-occurs with epilepsy and hypothyroidism (p < 0.001). Traditional classification facilitates the identification of a greater number of relationships and is therefore recommended for use in daily practice. There is a need to standardize the definition of microcephaly and macrocephaly and to include them in 'Human Phenotype Ontology' terms.

Abnormal Head Size in Children and Adolescents with Congenital Nervous System Disorders or Neurological Syndromes with One or More Neurodysfunction Visible since Infancy.

The current study was designed to investigate co-occurrence of absolute/relative microcephaly, absolute/relative macrocephaly and congenital nervous system disorders or neurological syndromes with symptoms visible since infancy, based on fundamental data acquired during the admission procedure at a neurological rehabilitation ward for children and adolescents. The study applied a retrospective analysis of data collected during the hospitalization of 327 children and adolescents, aged 4-18 years, affected since infancy by congenital disorders of the nervous system and/or neurological syndromes associated with a minimum of one neurodysfunction. To identify subjects with absolute/relative microcephaly, absolute/relative macrocephaly in the group of children and adolescents, the adopted criteria took into account z-score values for head circumference (z-score hc) and head circumference index (z-score HCI). Dysmorphological (x+/-3s) and traditional (x+/-2s) criteria were adopted to diagnose developmental disorders of head size. Regardless of the adopted criteria, absolute macrocephaly often coexists with state after surgery of lumbar myelomeningocele and hydrocephalus, isolated hydrocephalus, hereditary motor and sensory polyneuropathy, and Becker's muscular dystrophy (p < 0.001, p = 0.002). Absolute macrocephaly is often associated with neural tube defects and neuromuscular disorders (p = 0.001, p = 0.001). Relative microcephaly often occurs with non-progressive encephalopathy (p = 0.017, p = 0.029). Absolute microcephaly, diagnosed on the basis of traditional criteria, is often associated with epilepsy (p = 0.043). In children and adolescents with congenital nervous system disorders or neurological syndromes with one or more neurodysfunction visible since infancy, there is variation in abnormal head size (statistically significant relationships and clinical implications were established). The definitions used allowed for the differentiation of abnormal head size.

Can an Observational Gait Scale Produce a Result Consistent with Symmetry Indexes Obtained from 3-Dimensional Gait Analysis?: A Concurrent Validity Study.

To investigate whether a simple observational tool may be a substitute to the time-consuming and costly 3-dimensional (3D) analysis, the study applied the Wisconsin Gait Scale (WGS), enabling assessment which is highly consistent with 3D gait parameters in patients after a stroke. The aim of this study was to determine whether, and to what extent, observational information obtained from WGS-based assessment can be applied to predict results of 3D gait analysis for selected symmetry indicators related to spatiotemporal and kinematic gait parameters. Fifty patients at a chronic stage of recovery post-stroke were enrolled in the study. The spatiotemporal and kinematic gait parameters were measured using a movement analysis system. The symmetry index (SI), was calculated for selected gait parameters. The patients' gait was evaluated by means of the WGS. It was shown that stance % SI, as well as hip and knee flexion-extension range of motion SI can most effectively be substituted by WGS-based estimations (coefficient of determination exceeding 80%). It was shown that information acquired based on the WGS can be used to obtain results comparable to those achieved in 3D assessment for selected SIs of spatiotemporal and kinematic gait parameters. The study confirms that observation of gait using the WGS, which is an ordinal scale, is consistent with the selected aims of 3D assessment. Therefore, the scale can be used as a complementary tool in gait assessment.

Growth disorders in children and adolescents affected by syndromes or diseases associated with neurodysfunction.

We have observed that one in three patients admitted to the Neurological Rehabilitation Ward for Children and Adolescents due to a syndrome or disease associated with neurodysfunction is short of stature for their age. In order to identify the relationship between growth defects (short stature) and syndromes or diseases associated with neurodysfunction, we analyzed data collected during admission to the Neurological Rehabilitation Ward for Children and Adolescents. The study applied a retrospective analysis of data collected during hospitalization of 327 children and adolescents, aged 4-18 years, affected by congenital disorders of the nervous system and/or neurological syndromes associated with a minimum of one neurodysfunction. Two assessment systems were taken into account - one system traditionally applied, and another one in accordance with indications approved by the Food and Drug Administration, related to diagnosing short stature. The findings show more frequent co-occurrence of, as well as statistically significant correlations between, short stature in certain groups: operated myelomeningocele with hydrocephalus in the subgroup of neural tube defects (p = 0.029), tetraplegia in the subgroup of spastic cerebral palsy (p < 0.001), and hypothyroidism (p = 0.04) in the entire study group.

Evaluation of vitamin D3 levels and morphotic parameters of blood in prematurely born children at six years of age.

In Poland the preterm children, with the birth rate reaching 6.3%, constitute a serious medical problem. The system of specialistic clinics provides them with the multidisciplinary care for the first 3 years of life, including the monitoring of hematologic parameters in relation with anemia and osteopenia. The aim of this study was to assess the vitamin D3 level and morphotic parameters of blood in children who were prematurely born at the time when they are about to start school. The study was carried out in a group of 92 children, aged 6 years ±0.63, including 54 preterm children born at gestational age <32 weeks - and 38 full-term children. A basic anthropometric measures and assessment of morphotic parameters and the vitamin D3 level were assessed. Statistical analyses were carried out using Shapiro-Wilk W-test, Student's t-test and Mann-Whitney U test. Preterm children had significantly lower the vitamin D3 level than controls. This also refers to some morphotic parameters of blood, such as level of hemoglobin, mean corpuscular hemoglobin concentration and platelets. Prematurely born 6-7 year-old children have significantly lower vitamin D3 levels in blood serum than normal and significantly lower hemoglobin levels than full-term children.
