Zero-echo time MRI: an alternative method for the diagnosis of urinary stones in children.

OBJECTIVES: To evaluate the potential of zero-echo time-magnetic resonance imaging (ZTE-MRI) in the assessment of urolithiasis and compare ZTE-MRI with computed tomography (CT) in pediatric patients. MATERIALS AND METHODS: This was a single-center, prospective cross-sectional study conducted between April 2023 and December 2023. 23 patients (12 girls, 11 boys; mean age: 12.3, range 1-18) with urinary tract stones detected on non-enhanced abdominal CT were enrolled. The images were evaluated independently by two radiologists for the presence, and number of stones in the kidneys, ureters, and bladder. In the second session, two radiologists evaluated whether urinary tract stones could be detected by MRI compared to CT, and the maximum diameter of the stones was measured. The CT and MRI results were compared with the Wilcoxon test. The agreement between the results of the observers was examined using Spearman's rho correlation coefficient and the intraclass correlation coefficient. RESULTS: A total of 58 urinary tract stones were detected by CT and 39 of these were detected by MRI. Most of the stones that MRI could not detect were < 5 mm and the detection sensitivity of MRI increased in correlation with stone size (p < 0.001). There was poor intermodality agreement for stones < 5 mm, substantial agreement for stones 5-10 mm, and almost perfect agreement for stones > 10 mm. Interobserver agreement for stone detection on MRI was almost perfect for stones > 10 mm and 5-10 mm and was substantial for stones < 5 mm. CONCLUSION: ZTE-MRI is a promising modality for detecting urinary stones without radiation exposure in children. CLINICAL RELEVANCE STATEMENT: Zero-echo time-magnetic resonance imaging is a potential method for identifying urinary stones in children and other populations who are particularly sensitive to radiation. KEY POINTS: Urinary system stone disease in children is increasing and imaging is needed for managing urolithiasis. Zero-echo time-magnetic resonance imaging (ZTE-MRI) had an accuracy of 81.8% and 93.7% for stones larger than 5 mm and 10 mm, respectively. ZTE-MRI is a potential non-irradiating method for the diagnosis and management of urolithiasis.

Liver magnetic resonance elastography and fat fraction in pediatric patients with cystic fibrosis versus healthy children.

BACKGROUND: Liver involvement is an important cause of morbidity and mortality in patients with cystic fibrosis (CF). While liver biopsy is the gold standard for demonstrating involvement, its invasiveness prompts a search for noninvasive alternatives. OBJECTIVE: To evaluate liver involvement in pediatric patients with CF (versus healthy controls) using magnetic resonance (MR) elastography/spectroscopy and to correlate the imaging findings with clinical/laboratory characteristics. MATERIALS AND METHODS: This was a single-center, prospective cross-sectional study conducted between April 2020 and March 2022 in patients with CF versus healthy controls. Patients with CF were divided into two subgroups: those with CF-related liver disease and those without. MR images were acquired on a 1.5-tesla machine. Kilopascal (kPa) values were derived from processing MR elastography images. MR spectroscopy was used to measure liver fat fraction, as an indication of hepatosteatosis. Groups were compared using either the Student's t test or the Mann‒Whitney U test. The chi-square test or Fisher's exact test were used to compare qualitative variables. RESULTS: Fifty-one patients with CF (12 ± 3.3 years, 32 boys) and 24 healthy volunteers (11.1 ± 2.4 years, 15 boys) were included in the study. Median liver stiffness (P=0.003) and fat fraction (P=0.03) were higher in the CF patients than in the controls. Median liver stiffness values were higher in CF patients with CF-related liver disease than in those without CF-related liver disease (P=0.002). Liver stiffness values of CF patients with high alanine aminotransferase (ALT), high gamma-glutamyl transferase, and thrombocytopenia were found to be higher than those without (P=0.004, P<0.001, P<0.001, respectively). Only the high ALT group showed a high fat fraction (P=0.002). CONCLUSIONS: Patients with CF had higher liver stiffness than the control group, and patients with CF-related liver disease had higher liver stiffness than both the CF patients without CF-related liver disease and the control group. Patients with CF had a higher fat fraction than the control group. Noninvasive assessment of liver involvement using MR elastography/spectroscopy can support the diagnosis of CF-related liver disease and the follow-up of patients with CF.

Effects of nasoalveolar molding on maxillary arch dimensions and malocclusion characteristics in primary dentition patients with cleft lip and palate.

BACKGROUND: Nasoalveolar molding (NAM) is a presurgical orthopedic technique used in the management of cleft lip and palate deformities. Despite the widespread use of NAM therapy, there is a need for further investigation to assess its specific effects on arch dimensions and malocclusion characteristics. AIM: To evaluate the effects of NAM therapy on maxillary arch dimensions and malocclusion characteristics in patients with unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP). DESIGN: Patients in primary dentition were referred to the Institutional Department of Orthodontics. The NAM group consisted of 21 patients with UCLP (mean age 4.7 ± 0.7 years) and 12 patients with BCLP (mean age 4.8 ± 0.7 years). Sixteen patients with UCLP (mean age 4.9 ± 0.9 years) and five patients with BCLP (mean age 5.4 ± 1.1 years) were included in the non-NAM group. The plaster models of all patients were digitized. Dental arch dimensions and malocclusion characteristics were analyzed via digital software. One-way ANOVA with Bonferroni correction was used for statistical analysis. RESULTS: Intercanine and intermolar widths showed statistically significant differences according to the cleft type (p < .01). There was no statistically significant effect of NAM therapy on maxillary arch parameters and malocclusion characteristics (p > .05). The prevalence of anterior crossbite was 12.1% in the NAM group and 23.8% in the non-NAM group. CONCLUSION: NAM therapy did not affect the maxillary arch dimensions and malocclusion characteristics in patients with UCLP and BCLP. The cleft type was the main factor, leading to a significant difference in maxillary widths.

Changing Disease Course of Crimean-Congo Hemorrhagic Fever in Children, Turkey.

Crimean-Congo hemorrhagic fever (CCHF), endemic in certain regions of the world, is listed as a priority disease with pandemic potential. Since CCHF was first identified in Turkey, children have been known to experience milder disease than adults. However, during the COVID-19 pandemic, we observed an unusually severe disease course, including hemophagocytic lymphohistiocytosis (HLH). We examined cytokine/chemokine profiles of 9/12 case-patients compared with healthy controls at 3 time intervals. Interferon pathway-related cytokines/chemokines, including interleukin (IL) 18, macrophage inflammatory protein 3α, and IL-33, were elevated, but tumor necrosis factor-α, IL-6, CXCL8 (formerly IL-8), and cytokines acting through C-C chemokine receptor 2 and CCR5 were lower among case-patients than controls. Interferon pathway activation and cytokines/chemokines acting through CCR2 and CCR5 improved health results among children with severe CCHF. Children can experience severe CCHF, including HLH, and HLH secondary to CCHF can be successfully treated with intravenous immunoglobulin and steroid therapy.

A new tool supporting the diagnosis of childhood-onset Behçet's disease: venous wall thickness.

OBJECTIVES: The lower extremity venous wall thickness (VWT) of Behçet's disease (BD) patients was reported to be significantly increased in adults, suggesting its use for the support of BD diagnosis. This prospective study aimed to investigate the lower extremity VWT in childhood-onset definite and incomplete BD patients and compare it to healthy age-matched controls. METHODS: Paediatric patients classified with BD according to the 2015 international paediatric BD criteria in our centre were included in the study. Intima-media thickness of the lower extremity veins to evaluate VWT was measured by ultrasonography, including common femoral vein (CFV), femoral vein (FV), vena saphena magna, vena saphena parva and popliteal vein (PV). RESULTS: In this cross-sectional study, VWT was measured in 35 patients (63% male) and 27 healthy controls (55% male). Thirteen (37%) of 35 patients met the criteria for the diagnosis of BD. The remaining 22 (63%) had incomplete BD and met two criteria. The median VWT values of both definite and incomplete BD patients were significantly higher than the control group in all veins on both sides. Regarding the best cut-off values of VWT for all lower extremity veins, the sensitivity rates were between 63% and 86%, while specificity rates were between 71% and 100%. CONCLUSION: Increased VWT was present not only in BD patients with vascular involvement but also in those without. We suggest that VWT may be a new criterion in supporting the diagnosis of childhood BD both in definite and incomplete BD patients.

Can we identify "at-risk" children and adolescents for poor transplant outcomes in the psychosocial evaluation before solid organ transplantation? The reliability and validity study of Pediatric Transplant Rating Instrument (P-TRI) in Turkish pediatric renal transplant patients.

BACKGROUND: This study aims to translate the Pediatric Transplant Rating Instrument (P-TRI) to conduct a validity and reliability study on Turkish children and define a cutoff value of this scale. METHOD: A total of 151 pediatric kidney transplant patients were included in the study. The files of the patients were reviewed by two clinicians, and the scale was filled for inter-rater reliability. One of the clinicians filled the scale again after one month for intra-rater reliability. Glomerular filtration rate (GFR) and creatinine values were used for predictive validity. A GFR below <60 ml/min/1.73 m2 and creatinine up to 3.0 mg/dl was defined as risk factors. RESULTS: Correlation of P-TRI with GFR (r = .252, p = .003) and creatinine (r = -.249, p = .002) was performed, and the internal consistency of the scale items as measured by Cronbach's alpha coefficient was found to be 0.825. When the test was performed again, the intra-class correlation coefficient was found as .922 for intra-rater reliability and as .798 for inter-rater reliability. For both creatinine and GFR, the best cutoff point for the total score was found to be 66.5. CONCLUSIONS: Patients who received P-TRI above 66.5 could be at risk in the post-transplant period. Identification of these patients before transplantation and following these young people more closely will aid in the prevention of serious consequences. The reliability and validity scores are satisfactory for use in transplantation clinics for psychosocial evaluation and compliance in Turkish pediatric renal transplantation patients.

Methylprednisolone use in children with severe pneumonia caused by severe acute respiratory syndrome coronavirus 2.

BACKGROUND: This study aimed to evaluate the effectiveness and optimal use of corticosteroids in children with severe coronavirus disease 2019 (COVID-19) pneumonia, for which effective treatment is still lacking with respect to this population. METHODS: We conducted a retrospective study and included patients (aged < 18 years) with severe COVID-19 pneumonia and/or acute respiratory distress syndrome (ARDS) who received standard doses (2-4 mg/kg/day) and high doses (>250 mg/day) of methylprednisolone (MPZ). We adjusted for patients on steroid treatments with a propensity score and compared the side effects of different MPZ doses and patient survival. RESULTS: Fifty-nine patients were included: 61% were male, the median age was 8, interquartile range (IQR) 2-15) years. The overall survival was 84.4% in patients treated with standard-dose MPZ (n = 45, 76.3%) and 92.2% in patients treated with high-dose MPZ (n = 14, 23.7%; p = 0.67). The demographic, clinical, and laboratory data did not differ significantly after propensity score matching, apart from bradycardia, which was a prominent feature of the high-dose group. The clinical and radiological response rates on day 7 were higher and the need for invasive mechanical ventilation (IMV) was lower in the high-dose group. CONCLUSION: The patients with high-dose MPZ had better clinical and radiological responses than those with standard-dose MPZ, although the mortality rate did not differ between standard and high-dose regimens of MPZ.

The comparison of COVID-19 vs seasonal influenza in children.

BACKGROUND: Influenza in children has been well described, whereas there has been a paucity of pediatric data regarding COVID-19. It is crucial for clinicians to differentiate cases of COVID-19 from cases of influenza because of the upcoming influenza season in the new pandemic era. METHODS: This retrospective study included pediatric patients who were diagnosed with laboratory-confirmed COVID-19 between March and September 2020, or seasonal influenza between October 2019 and March 2020. RESULTS: A total of 315 children were included in this study; 151 were diagnosed with influenza and 164 had confirmed COVID-19. The median age of patients with COVID-19 was 10 years (interquartile range [IQR]: 3-15 years), whereas the median age of patients with influenza was 4 years (IQR: 1-6 years) (p = 0.001). In the COVID-19 group, 6.3% of patients had underlying diseases, the most frequent being neurological conditions (3%). In the influenza group, 20.9% of patients had an underlying disease, the most frequent being asthma (14.5%). Fever (odds ratio [OR]: 20.476; 95% confidence interval [CI]: 2.438-171.995; p = 0.005), dyspnea/tachypnea (OR 13.950; 95% CI: 2.607-74.634; p = 0.002), and increased C-reactive protein (CRP) (OR: 7.650; 95% CI: 2.094-27.955; p = 0.002) were main predictors of influenza diagnosis in comparison to COVID-19. Lymphopenia was detected in 43.2% of patients with influenza and 19.9% of patients with COVID-19 (p = 0.001). CONCLUSIONS: The accurate differentiation between "influenza or COVID-19" seems possible by evaluating a combination of factors including cough, fever, vomiting, leucopenia, lymphopenia, pneumonia, in pediatric patients with high CRP as well as age.

The effect of sacral massage on meconium-stained amniotic fluid and the duration of fetal descent in labor: A randomized controlled trial.

OBJECTIVE: The aim of this study was to investigate the effect of sacral massage on the presence of meconium-stained amniotic fluid and the duration of fetal descent during labor in pregnant women. METHODS: A total of 220 nulliparous women with singleton low-risk pregnancies in the vertex position at term were recruited. Eligible women were randomly assigned to either massage group or a control group. The massages were performed with friction and tapotement protocol. The massage was applied for 10 min each time by a midwife who is also an expert in the field, at the onset of contractions during the intrapartum period, when cervical dilatation reached 10 cm. The Wong-Baker faces pain rating scale was evaluated. RESULTS: No significant difference was found between the length of the first stage of labor and the total length of delivery (p = 0.097 and 0.434), respectively. There was a significant difference between the two groups in terms of perineal injuries. Perineal injury was lower in the massaged group (p = 0.005). There was a low percentage of meconium-stained amniotic fluid in the massaged group. The difference between the groups was statistically significant. The duration of fetal descent was shorter in the massaged group (p < 0.001). A significant difference was found in Wong-Baker FACES pain rating scale scores. Lower scores were detected in the massaged group (p < 0.001). CONCLUSION: Sacral massage has beneficial effects on mothers and babies in obstetric practice. In addition, applying massage during labor plays a significant role in reducing the presence of meconium-stained amniotic fluid and the duration of fetal descent.

Influence of video display terminal use and meibomian gland dysfunction on the ocular surface and tear neuromediators.

OBJECTIVE: To evaluate the effects of video display terminal (VDT) work and meibomian gland dysfunction (MGD) on ocular surface parameters, tear cytokine and substance P (SP) levels, and their association with dry eye disease (DED). METHODS: This cross-sectional study included 60 patients with evaporative DED and 20 healthy individuals. The DED patients were divided into three groups according to daily VDT work time and presence of MGD. The ocular surface and tear film were assessed using the Ocular Surface Disease Index questionnaire (OSDI), tear film break-up time (TBUT), ocular surface staining, Schirmer II test, and corneal sensitivity. MGD was evaluated with meibography. Corneal nerve alterations were evaluated using in vivo confocal microscopy (IVCM). The tear levels of 30 cytokines and SP were examined. RESULTS: Compared to controls, DED patients had higher OSDI score (p < 0.001), increased corneal staining with fluorescein and lissamine green (p = 0.046, p = 0,038), and lower TBUT (p < 0.001). Tear interleukin-6 levels were higher in DED patients, while tear SP levels did not differ between the groups (p = 0.265). VDT work time showed a weak positive correlation with OSDI (r = 0.274, p = 0.014) and SP level (r = 0.284, p = 0.011). CONCLUSION: The results of this study show that VDT use and MGD have an adverse effect on the ocular surface. It was also observed that the combination of VDT use and MGD did not significantly increase the ocular surface disease, but longer VDT exposure may be associated with more complaints of ocular discomfort.

Effect of retrobulbar prostaglandin analog injection on orbital fat in rats.

PURPOSE: Periorbital fat atrophy is a known side effect of topical prostaglandin analogs (PA). This side effect may have implications in the treatment of diseases like thyroid orbitopathy. In this in vivo study we aimed to evaluate the effects of retrobulbar injection of three different PAs on orbital fat. METHODS: Eighteen adult male Wistar-albino rats were divided into three groups of six animals. 0.1 ml of 0.03% bimatoprost, 0.005% latanoprost, or 0.005% travoprost was injected into the right orbits and saline was injected into the left orbits, as controls. Both orbits were exenterated after 3 weeks. Histological cross-sections were analyzed using ImageJ image analysis software. Intraconal adipocyte density was calculated. RESULTS: There was no significant difference in the adipocyte density between the PA injected orbits and the control side in each of the three groups. When calculations from all three groups were analyzed together, again the difference in the adipocyte density between the PA injected orbits and the control side was not significant. CONCLUSION: No significant fat atrophy was noted in this rat model three weeks after retrobulbar injection of PAs. To evaluate retrobulbar injection of PA as a potential therapy for orbital diseases with fat proliferation, in vivo studies in different animal models, higher concentrations of PA, or longer follow-up duration are required.

Different Attenuation Models of Diffusion-Weighted MR Imaging for the Differentiation of Benign and Malignant Musculoskeletal Tumors.

BACKGROUND: Several functional imaging techniques, including monoexponential diffusion-weighted imaging (m-DWI), intravoxel incoherent motion (IVIM), and diffusion kurtosis (DK) imaging, have been used in differentiating benign and malignant musculoskeletal tumors. Combining all three techniques in the same study population may improve differentiation. PURPOSE: To compare the diagnostic performance of m-DWI, IVIM, and DK models and their combinations in differentiating benign and malignant musculoskeletal tumors. STUDY TYPE: Prospective. POPULATION: Fifty patients with benign and malignant musculoskeletal tumors divided into nonmyxoid and nonchondroid and myxoid and/or chondroid subgroups. FIELD STRENGTH/SEQUENCE: A 1.5 T/m-DWI, IVIM, and DK single-shot spin-echo echo-planar sequences. ASSESSMENT: Minimum and volumetric values of apparent diffusion coefficient (ADC), pure molecular diffusion (Divim ), pseudodiffusion (D*), perfusion fraction (f), diffusion coefficient for kurtosis model (DK ), and Kurtosis (K) were compared between all benign and malignant tumors. Subgroup analysis was also performed for nonmyxoid and nonchondroid and myxoid and/or chondroid tumors. STATISTICAL TESTS: Independent samples t-test, Mann-Whitney U test, intraclass correlation coefficient, ROC analysis, and logistic regression analysis. A P value < 0.05 was considered statistically significant. RESULTS: ADCmin , Divim-min , D*vol , DK-min, Kvol, and Kmin values showed statistically significant differences between all benign and malignant tumors and nonmyxoid and nonchondroid tumor subgroup. Kmin showed the highest diagnostic performance in differentiating benign and malignant tumors with AUCs of 0.760 for "all tumors" and 0.825 for the nonmyxoid and nonchondroid tumor subgroup. No significant differences were detected in m-DWI-, IVIM-, and DK-derived parameters for differentiating benign and malignant myxoid and/or chondroid tumors. Only three of 63 combinations of prediction models demonstrated a higher diagnostic performance than Kmin ; however, improvements were not significantly different. DATA CONCLUSION: ADCmin , Divim-min , D*vol , DK-min , Kvol , and Kmin values can be used to differentiate benign and malignant musculoskeletal tumors. Our findings suggest that the added value of multiparametric approach in such differentiation is not significant. EVIDENCE LEVEL: 1 TECHNICAL EFFICACY: Stage 2.

The difference of the inflammatory milieu in MIS-C and severe COVID-19.

BACKGROUND: Coronavirus disease 19 (COVID-19) may have a severe course in children. Multisystem inflammatory syndrome in children (MIS-C) is the post-COVID complication characterized by an exaggerated inflammation, observed in children. However, data on the underlying pathophysiology are sparse. We therefore aimed to assess the cytokine and chemokine profiles of children with MIS-C and compare these to life-threatening severe SARS-CoV-2 and healthy controls (HCs) to shed light on disease pathophysiology. METHODS: Samples of 31 children with MIS-C, 10 with severe/critical COVID-19 and 11 HCs were included. Cytokine and chemokine profiles were studied and compared in between groups. RESULTS: Most cytokines and chemokines related to IL-1 family and IFN-γ pathway (including IL-18 and MIG/CXCL9) and IL-17A were significantly higher in the MIS-C group when compared to the severe/critical COVID-19 group and HCs. IP-10/CXCL10 and IL-10 were higher in both MIS-C patients and severe/critical COVID-19 compared to HCs. CONCLUSION: Our results suggest that IL-1 and IFN-γ pathways play an important role in the pathophysiology of MIS-C. IMPACT: This study defines a pattern of distinctive immune responses in children with MIS-C and in patients with severe/critical COVID-19. As the COVID-19 pandemic continues, biomarkers to identify MIS-C risk are needed to guide our management that study results may shed light on it.

Reduced myelin in patients with isolated hippocampal sclerosis as assessed by SyMRI.

PURPOSE: Synthetic MRI (SyMRI) enables to quantify brain tissue and morphometry. We aimed to investigate the WM and myelin alterations in patients with unilateral hippocampal sclerosis (HS) with SyMRI. METHODS: Adult patients with isolated unilateral HS and age-matched control subjects (CSs) were included in this study. The SyMRI sequence QRAPMASTER in the coronal plane perpendicular to the hippocampi was obtained from the whole brain. Automatic segmentation of the whole brain was processed by SyMRI Diagnostic software (Version 11.2). Two neuroradiologists also performed quantitative analyses independently from symmetrical 14 ROIs placed in temporal and extratemporal WM, hippocampi, and amygdalae in both hemispheres. RESULTS: Sixteen patients (F/M = 6/10, mean age = 32.5 ± 11.3 years; right/left HS: 8/8) and 10 CSs (F/M = 5/5, mean age = 30.7 ± 7 years) were included. Left HS patients had significantly lower myelin and WM volumes than CSs (p < .05). Myelin was reduced significantly in the ipsilateral temporal lobe of patients than CSs, greater in left HS (p < .05). Histopathological examination including luxol fast blue stain also revealed myelin pallor in all of 6 patients who were operated. Ipsilateral temporal pole and sub-insular WM had significantly reduced myelin than the corresponding contralateral regions in patients (p < .05). No significant difference was found in WM values. GM values were significantly lower in hippocampi in patients than CSs (p < .05). CONCLUSION: SyMRI revealed myelin reduction in the ipsilateral temporal lobe and sub-insular WM of patients with HS. Whether this finding correlates with electrophysiological features and SyMRI could serve as lateralization of temporal lobe epilepsy need to be investigated.

Investigation of anterior segment structures of the eye in Behçet's disease using in vivo confocal microscopy.

PURPOSE: We sought to investigate alterations in the corneal subbasal nerve plexus and endothelium in patients with Behçet's disease (BD). METHODS: This cross-sectional study included 64 patients with BD and 30 age- and gender-matched healthy control subjects. Those with BD were classified as having ocular or non-ocular disease. All subjects underwent a corneal endothelial and subbasal nerve density evaluation using in vivo confocal microscopy (IVCM). The differences among groups were analyzed using the Kruskal-Wallis test followed by Dunn's multiple comparison procedure. RESULTS: The mean age of study participants was 35.7 ± 10.2 years (16-58) in the ocular BD group, 39.6 ± 14.9 years (11-66) in the non-ocular BD group, and 34.1 ± 11.2 years (21-55) in the control group. No statistical significance was found in terms of age (p = 0.259) or sex (p = 0.560) between groups. The mean endothelial cell density determined with IVCM was 2124.9 [Formula: see text] 417.4 cells/mm2 (1811-3275) in the ocular group and 2546 [Formula: see text] 335 cells/mm2 (1798-3280) in the control group (p = 0.000). In the ocular group, the mean density of the subbasal nerve plexus was significantly lower (p = 0.004), and nerve tortuosity was significantly higher (p = 0.002). CONCLUSIONS: Ocular BD could be responsible for changes in the corneal layers, especially endothelial and corneal nerve structures. Nerve density and tortuosity differences could be inflammatory indicators for BD.

The reliability, validity, and responsiveness of Cognitive Exercise Therapy Approach: Biopsychosocial Questionnaire for patients with psoriatic arthritis.

Although the importance of the biopsychosocial model that aims the optimum treatment is emphasized in the literature, there is a lack of scales that evaluate individuals with PsA in a multi-dimensional way, including all areas of influence. This study aimed to determine the validity, reliability, and responsiveness of the Cognitive Exercise Therapy Approach-Biopsychosocial Questionnaire (BETY-BQ) in individuals diagnosed with Psoriatic Arthritis (PsA). Psoriatic Arthritis Quality of Life Questionnaire (PsAQoL), Health Assessment Questionnaire, Hospital Anxiety and Depression Scale, and Short Form-36 were used for the validity of the BETY-BQ. For scale reliability, the test-retest method was performed, Intraclass Correlation Coefficient (ICC) was calculated, and Cronbach's alpha (α) coefficient was checked for internal consistency. For the responsiveness of the scale, all scales were re-applied with 3 months intervals. The correlations of BETY-BQ with the other scales were found medium to very high. ICC was analyzed to compare the reliability of the test-retest results and it was found to be excellent. Cronbach's α value was found to be 0.940 which showed an excellent internal consistency. The time-dependent change sensitivity of BETY-BQ was found to be highly correlated with the PsA-specific scale, the PsAQoL questionnaire. BETY-BQ was determined as a valid, reliable, and sensitive assessment tool that health professionals can use in individuals with PsA diagnosis. In this study, a scale that will reveal the biopsychosocial responses of individuals with PsA to pharmacological and non-pharmacological treatments was presented to the literature.

Assessment of systemic and ocular inflammation in juvenile idiopathic arthritis via choroidal vascularity index.

We aimed to evaluate the retina and the choroid in children with juvenile idiopathic arthritis (JIA) employing optical coherence tomography (OCT). This cross-sectional study, carried out between June 2017-December 2019, included JIA patients with (JIAU; n = 28) and without (JIAN; n = 65) uveitis and age-matched healthy controls (HC) (n = 102). Laboratory and demographic information of the children were obtained from hospital records. Activity of the disease was evaluated by the Juvenile Arthritis Disease Activity Score-71 (JADAS-71). Choroidal scans were obtained with spectral domain-OCT in enhanced-depth imaging (EDI)-OCT mode to assess choroidal thickness (ChT) at five locations (under the fovea, at 750 and 1500 µm nasal and temporal sections), luminal area (LA), stromal area (SA), total subfoveal choroidal area (TCA) and CVI (choroidal vascularity index). Central foveal thickness (CFT) and 1-mm diameter foveal thickness (FT) were calculated automatically through macular volume scan analysis. The choroid was significantly thicker in JIAU and JIAN patients than in HC at the subfoveal and at the 750N, 750T, 1500T points (p < 0.001, p = 0.009, p < 0.001, and p < 0.001, respectively). The CVI was lower in JIAU patients than in JIAN patients and HC (p = 0.02). Conversely, CFT was greater in JIAU patients as compared to the JIAN patients and HC (p = 0.02). Changes in chorioretinal OCT parameters in the absence of uveitis in JIA patients may reflect subclinical choroidal inflammation in these patients. Ophthalmologic examination, including choroidal imaging in a larger cohort, may clarify this aspect.

Sliced vs crushed cartilage for camouflage: long-term graft survival and histological outcomes.

PURPOSE: In this study, we proposed a "sliced-partial thickness cartilage graft" for nasal contour restoration purposes and compared the long-term graft survival and histological changes of sliced, crushed, and intact cartilage grafts. METHODS: Nasal septal and auricular cartilage grafts were harvested from 8 rabbits. Sliced, crushed, or intact cartilage grafts were measured in thickness with a micrometer and re-implanted. 4 months later, specimens were histologically evaluated and thickness were measured. RESULTS: Both nasal septal and auricular crushed cartilage lost significantly more chondrocytes than sliced samples together with fibrosis, multiple fracture lines, and even ossification. Sliced and intact cartilages were histologically similar except sliced cartilage had some minor changes limited to its cut surface. Sliced cartilages retained their thickness, histology, and structural properties in the long term similar to intact cartilages whereas -contrary to expectations- crushed specimens had significantly higher thickness measurements at the end of 4 months. CONCLUSION: Sliced cartilage grafts prepared with an atraumatic cartilage slicer are an ideal camouflaging material with its uniform thickness, and malleability. Crushed cartilages seemingly getting thicker without histological findings could be explained by lower than actual initial measurements due to its structural weakness and getting squeezed when the standard pressure of the micrometer was applied.

Elucidating the level of developmental risk in a busy paediatric practice clinic from a middle-income country.

BACKGROUND: Identifying young children with serious developmental concerns is a common challenge in paediatric settings around the world. Elucidating parental concerns about their children's development is a useful predictor of developmental status. The aim of this study is to elucidate the level of developmental risk in a busy outpatient paediatric clinic using the Parents' Evaluation of Developmental Status (PEDS) and observe the associated factors in a middle-income country. METHODS: Parents attending a medical appointment for their children in a paediatric outpatient clinic were asked to complete the PEDS and a questionnaire pertaining to sociodemographic details. A total of 151 parents were eligible to participate in the study. Parents also rated the ease of completion of the test with the response options being 'difficult, a little difficult, easy, very easy'. RESULTS: In our total sample, 9.3% (n = 14) were at high risk, 16.6% (n = 25) were at moderate risk and the remainder were at low/no risk. Being at high or moderate risk (25.8%, n = 39) was higher in male gender (p = 0.046) and older age children (p = 0.004). Hospitalization in a neonatal intensive care unit longer than 3 days, maternal employment status/housewife, long duration of screen viewing were independent risk factors significantly associated with high or moderate risk in multivariable analyses. Among the participants, 98.7% of parents reported that the PEDS was easy or very easy to complete in the clinical setting. CONCLUSION: In this study, in a cosmopolitan city of a middle-income country, a quarter of children were observed to be at high or moderate risk. The findings highlight the importance of elucidating the prevalence of developmental concerns among the population to enable families to access universal high-quality early childhood services.

Relationship of depression, impulsivity, distress intolerance and coping styles with maladaptive eating patterns in bariatric candidates.

PURPOSE: The study aimed to investigate the problematic eating patterns and understand their relationship to psychological constructs, including stress intolerance, coping mechanisms and impulsivity, and psychiatric symptoms among bariatric surgery candidates. METHODS: The bariatric candidates were evaluated by psychiatric interview and standard scales assessing maladaptive eating behaviors (Eating Attitudes Test (EAT), Bulimia Investigatory Test-Edinburgh (BITE), Dutch Eating Behavior Questionnaire (DEBQ)), depression (Beck Depression Inventory (BDI)), psychiatric symptoms (Brief Symptom Inventory (BSI)), and psychological constructs (Distress Intolerance Index (DSI), Coping Styles Scale (CSS), UPPS Impulsive Behavior Scale(UPPS)). RESULTS: More than half (57.8%) had maladaptive eating behaviors, and 23.6% had binge-eating behavior. Depression and anxiety predicted EAT, BITE, and DEBQ emotional and external eating sub-scale scores; distress intolerance, helpless coping style, and impulsivity predicted maladaptive eating behaviors in bariatric candidates. CONCLUSION: Maladaptive eating patterns play an essential role in the failure to lose weight and regain weight and are predicted by depression, anxiety, and psychological constructs in this study. Evaluation of pathological trait characteristics besides discrete psychiatric syndromes should be recommended in the pre-operation process to plan relevant interventions in the long-term management of weight. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort analytic studies.
