Recognizing the Frequency of Exposure to Cyberbullying in Children: The Results of the National HBSC Study in Serbia.

Nowadays, children are able to enrich their reality via the Internet. Unfortunately, this may increase their risk of becoming victims of cyberbullying. We analyzed the health characteristics and risk behavior of two cohorts of children in Serbia; those who reported being exposed to cyberbullying and those who did not. The statistical differences and logistic regression models were applied to the data on 3267 students collected from 64 schools participating in the 2017 Serbian Study on health behavior in school-age children (HBSC). Children exposed to cyberbullying reported having the following health problems on a daily basis: headache (18.5%), back pain (19.5%), depression (21.6%), irritability or bad mood (17.7%), nervousness (16.0%), sleep problems (16.1%), and dizziness (21.2%). As for the different types of risk behavior, cigarette smoking ranging from six to nine days ever was the most prevalent (26.9%). It was followed closely by getting drunk more than 10 times ever (24.1%). Compared to non-victims, victims were found to be at a higher risk of perceived back pain (OR = 2.27), depression (OR = 1.43), irritability or bad mood (OR = 2.07), nervousness (OR = 2.23), and dizziness (OR = 2.43) as well as being injured once or twice (OR = 1.98) or three or more times (OR = 4.09). Victims were associated with further risk factors: having smoked more than five cigarettes ever in life (OR = 1.73) and having gotten drunk two to three times (OR = 1.71) or four or more times (OR = 1.65). As the number of school-age children using social media continues to rise, we must prioritize educating them about self-help and community resources for addressing related health issues with greater speed and intensity. The findings from Serbia suggest that while children may be aware of their health issues, they may be unaware of their link to cyberbullying, which could hinder their ability to address these issues promptly. The respondents' attention to the health implications of cyberbullying could be increased by reformulating the survey questions used in the HBSC study.

Cross-Cultural Adaptation and Quantitative Evaluation of Dysfunctional Voiding and Incontinence Scoring System in Pediatric Serbian Population.

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-off value for DVISSSR. 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 DVISSSR scores was done by receiver operating curve (ROC) curve. Results: There was a significant difference in DVISSSR 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.

Validation of Serbian Version of Dysfunctional Voiding Symptom Score (DVSS) Questionnaire.

OBJECTIVE: The aims of our study were to translate the dysfunctional voiding symptom score (DVSS) from English to Serbian; culturally adopt the items; assess the internal consistency and the test⁻retest reliability of DVSSSR in patients with dysfunctional voiding (DV); evaluate and test the construct and divergent validity of DVSSSR against demographic parameters (gender and education); and examine the level of explained variability for each item of DVSSSR against demographic parameters (gender and education). METHODS: The cross-sectional observational study included 50 patients with dysfunctional voiding aged 5 years and above. The DVSS questionnaire was translated from English into Serbian by the forward⁻backward method. Internal consistency was assessed with Cronbach α and test⁻retest reliability with intraclass correlation coefficient (ICC). For validity testing we performed construct and divergent validity analyses. RESULTS: There was excellent internal consistency for every item except for Item 6 (0.787) and Item 3 (0.864), where internal consistency was good. The observed test/retest ICC for average measures was more than 0.75 (excellent) for all DVSSSR items. Gender and educational level does not correlate significantly with each item of DVSSSR (p > 0.05). For divergent validity, there were no significant differences in mean values of each item of DVSSSR between genders and different levels of education (p > 0.05). Variability that can be explained for gender and educational level was below 10%. CONCLUSION: Translated DVSSSR is of adequate validity and reliability for assessing DV in children.

Validation of the Serbian Version of Multiple Sclerosis Spasticity Scale 88 (MSSS-88).

OBJECTIVE: Multiple Sclerosis Spasticity Scale (MSSS)-88 has been developed for self-assessment of spasticity symptoms in patients with multiple sclerosis (MS). The objective of this study was to validate MSSS-88 and evaluate the psychometric properties in patients with MS in Serbia. METHODS: The study comprised 65 MS patients with spasticity. MSSS-88 consists of 88 items grouped in eight sections. Internal consistency of the MSSS-88SR subscales was determined using Cronbach's alpha coefficient. Test/retest reliability with an intra-class correlation coefficient (ICC) for each MSSS-88SR subscale was performed. Clinical validity of MSSS-88SR was determined by correlations with the Numeric Rating Scale (NRS) and the Modified Ashworth Scale (MAS). RESULTS: The range of Cronbach's alpha for all scales and ICC was 0.91-0.96 and 0.84-0.91, respectively. All ICCs were statistically significant (p<0.05). All evaluated subscales of MSSS-88 were significantly correlated with the NRS scale. The highest correlation coefficients were registered between the WL subscale and the EDSS and MAS, while the strongest relationship was observed between the MSS subscale and the NRS. CONCLUSION: The Serbian translated version of this instrument may be useful as a clinical measure for spasticity and functionality in patients with MS.

Validity and reliability of the Serbian version of Patient-Reported Impact of Spasticity Measure in multiple sclerosis.

The Patient-Reported Impact of Spasticity Measure (PRISM) has been developed recently to assess the impact of spasticity on quality of life after spinal cord injury. Although PRISM may also be useful in patients with multiple sclerosis (MS), its psychometric properties in MS have not been established and PRISM is currently available only in English. The aims of this cross-sectional study were to translate PRISM into the Serbian language (PRISMSR) and examine its validity (construct, convergent, divergent) and reliability (internal consistency, test-retest reliability) in 48 patients with spasticity because of MS diagnosed at least 1 year earlier and in remission at least 3 months. PRISMSR was administered twice 3 days apart. The validity of seven PRISMSR subscales was examined against the Modified Ashworth Scale (MAS), the Numerical Rating Scale (NRS) for spasticity, sex, and education. Internal consistency was assessed with Cronbach α and test-retest reliability with intraclass correlation coefficient for agreement (ICC2,1). During the forward-backward translation, only one PRISM item required minor cultural adaption. Almost all PRISMSR scores correlated significantly with MAS and NRS scores (r=0.29-0.51, 0.001≤P≤0.043). They were all significantly higher for MAS≥2 group versus the MAS<2 group (0.003≤P≤0.035) and for the NRS≥7 group versus the NRS<7 group (0.001≤P≤0.042), except for the Social Embarrassment subscale (P=0.083). The PRISMSR scores were not significantly different between sexes (P≥0.104) or those with high school versus college degree (P≥0.139). Both Cronbach α (0.78-0.93) and test-retest ICC2,1 (0.82-0.90) were high. The original PRISM may be translated successfully into other languages. PRISMSR shows adequate validity and reliability for assessing the impact of spasticity on quality of life in patients with MS.

Evaluation of free-to-total prostate specific antigen (F/T PSA), prostate specific antigen density (PSAD) and (F/T)/PSAD sensitivity on reduction of unnecessary prostate biopsies for patients with PSA in gray zone.

AIM: We evaluated the influence of ratio between free-to-total prostate specific antigen (F/T PSA) and prostate specific antigen density (PSAD)-(F/T)/PSAD on reduction of unnecessary prostate biopsies in grey zone (prostate specific antigen (psa) value 4.0-10.0 ng/ml). METHODS: The study included 108 patients. For all patients serum total PSA (T PSA), free PSA (F PSA), F/T PSA and PSAD were analyzed. The group was divided due to the prostate volume into: entire group (regardless the prostate VOL-Group 1) and group with prostate VOL<40 (Group 2). RESULTS: Seventy five patients were diagnosed with benign prostatic hyperplasia (BPH) and 33 with prostate cancer (CaP). F/T PSA and (F/T)/PSAD showed significantly lower values in patients with CaP versus those with BPH, while PSAD had significantly higher values. For the cutoff values of 1.12 for (F/T)/PSAD, we found sensitivity to be 67% and specificity 60%, and the (AUC) 0.701. For patients with VOL<40, statistical significance remained with AUC of 0.732 (p=0.003), cutoff was 0.82, and with sensitivity 77% and specificity 68%. CONCLUSIONS: Most significant prostate carcinoma predictors were PSAD and (F/T)/PSAD, where we proposed that patients with (F/T)/PSAD values below 1.49 ± 0.94 and PSAD values above 0.17±0.06 should be included for biopsy.

Evaluation of visual evoked potentials in patient with angelmans syndrome - case report.

BACKGROUND: Angelman syndrome (AS) is a genetic disorder with varying degrees of neurological impairment. It is often associated with ocular involvement. CASE REPORT: We present a child diagnosed with AS who had a deletion on the short arm of chromosome 15. The child seemed to be happy, with developmental delay, speech problem, and altering strabismus. To assess the potential presence and degree of damage in the visual pathway, we recorded monocular flash visual evoked potentials (VEPs). Our results revealed the presence of severe central afferent dysfunction in both optical pathways. CONCLUSION: VEPs can be used in patients with AS and visual disturbances to assess the integrity of the visual system.

Distribution of affected muscles and degree of neurogenic lesion in patients with spina bifida.

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.

Type III longitudinal deficiency of the tibia and outcome of reconstructive surgery in a female patient.

Type III longitudinal deficiency of tibia according to Kalamchi and Dawe denotes the presence of distal hypoplasia of the tibia with diastasis. We report a case of type III longitudinal deficiency of the tibia in a female patient who later underwent reconstructive surgery. The first reconstruction of the leg was done when child turned 4 months of age. Surgical procedures included foot reconstruction and ankle stabilization with twice lengthening by the Ilizarov method (14 cm in total). During the follow-up, both the tibia and fibula of the affected leg showed the same lengthening and regression due to preserved distal growth zone cartilage. After surgical correction, the acetabulum was satisfactorily configured with an acetabular angle of 23 degrees. Explanation for surgical success was that osteotomy and distraction were done in the proximal part of the crural region where the growth potential was better. The tibia remained lean and hypoplastic while the fibula was incrassated. The function in the area of the knee joint was preserved, while the distal part of the leg served as good stand on. When the child was 18 years old, on check-up, the acetabular angle was 23 degrees while the Wiberg angle was 24 degrees.

Effects of electrotherapy in treatment of neurogenic bladder in children with occult spinal dysraphism.

INTRODUCTION: Neurogenic bladder can develop as a result of various degrees of neurogenic lesion in spina bifida. The degree of bladder dysfunction depends on the level and type of spina bifida. Due to results upon complete diagnostic protocols, treatment options are applied. OBJECTIVE: Comparison of therapy results of patients with occult spinal dysraphism with neurogenic bladder that underwent medicamentous therapy and medicamentous with electrotherapy treatment. METHODS: We had 49 patients with neurogenic bladder that were treated at the University Children's Hospital in Belgrade in the period 2003-2008. The first group of children received medicamentous therapy and the second group received medicamentous therapy with transcutaneous electric nerve stimulation. In both groups we evaluated 4 symptoms: daily enuresis, enuresis nocturna, urgency and frequency and 4 urodynamic parameters: lower bladder capacity, unstable contractions and residual urine and detrusor sphincter dyssynergia. Follow-up urodynamic evaluation was done after 3, 6 and 12 months respectively. RESULTS: Our findings pointed out a high statistical significance of improvement in all evaluated urodynamic parameters of neurogenic bladder (predominantly in bladder capacity) in the group of children with combined therapy as well in resolution of symptoms (predominantly enuresis nocturna, urgency and frequency). CONCLUSION: Combined therapy is more efficient in treatment of children with neurogenic bladder. Electrotherapy is non-invasive, easily applicable and has had a significant place in treatment of children with dysfunctional voiding.

[Early rehabilitation and cardiorespiratory response in children after correction of congenital heart defects].

INTRODUCTION: Significant improvement in survival and quality of life in patients after the correction of congenital heart defects was enabled by the introduction of surgical procedures. Due to increased vulnerability in the period after defect correction, early rehabilitation have found its place in recovery. Various studies suggest good effects of a rehabilitation programme especially in the early rehabilitation period. OBJECTIVE: In our study we wanted to stress the importance of early rehabilitation as well as its effects of implementation. METHOD: We evaluated the children treated at the University Children's Hospital during a four-year period. All participants were divided into two groups according to age: the first group included children up to the age of one year, and the second group included those from the first till the third year of life. Patients were divided into two groups according to the presence of complications. We monitored children with 4 types of congenital heart defects: Tetralogy of Fallot, Transposition of the Great Arteries, Coarctation of the Aorta and Stenosis of the Aorta. All exercises were implemented twice daily. Out of the pulmonary system parameters we monitored saturation of oxygen during the entire programme. Other parameters that were evaluated were: heart rate, ECG and breathing frequency. RESULTS: In the children with corrected defects, the most frequent complication was athelectasis especially in the group of patients till the first year of life. The patients with the onset of complications had a longer rehabilitation programme. Saturation of oxygen at the end of the programme was significantly elevated. CONCLUSION: From the above-mentioned it can be concluded that individual rehabilitation assessment for every patient is needed. Early rehabilitation measures give sustained effects of well-being after completion of the programme.
