Penetrating Craniocerebral Injury by the Hook of a School Desk.

INTRODUCTION: Although penetrating cranial injuries are rare in pediatric patients, these injuries can lead to morbidity and mortality. Removal of a gigantic foreign body from the cranium requires proper management as it has high risk of further brain damage and seizures. CASE PRESENTATION: We report the case of a patient with cranial injury caused by hitting the head to the hook of a school desk. Due to the extreme nature of the injury, the following additional steps were necessary: taking help from a local firefighter team to cut the desk, surgical removal of the foreign body, and cranioplasty after 6 months. Following this, he was discharged without neurological deficits. DISCUSSION/CONCLUSION: Neurotrauma is one of the major causes of death in children. The damage and effect of the injuring foreign body depends on its size, shape, velocity, trajectory, and entry point. It should be kept in mind that any high-frequency processes applied on the extracranial parts of conductive objects, such as metal bars, may trigger seizures. Preoperative extracranial intervention for huge penetrating foreign bodies should be performed under anticonvulsant administration and intubation to decrease the risk of epileptic seizures and its complications.

Accompanying migrainous features in pediatric migraine patients with restless legs syndrome.

The present study aimed to examine the frequency of restless legs syndrome (RLS) in pediatric patients with migraine and tension-type headache (TTH) and to investigate accompanying migrainous symptoms, sleep characteristics, as well as levels of serum ferritin between the pediatric migraine patients with RLS and those without RLS. We included 65 consecutive patients diagnosed with migraine, 20 patients with TTH, and 97 headache-free children in our study. Demographic, clinical, and laboratory data were noted. The presence of a primary headache was diagnosed using the ICHD-II criteria, and RLS was determined with face-to-face interviews conducted by an experienced neurologist based on the revised International RLS Study Group criteria for pediatrics. The frequency of RLS in pediatric migraine and TTH patients was significantly higher than in the controls (p = 0.0001 and p = 0.025, respectively). The frequencies of allodynia, vertigo/dizziness, and self-reported frequent arousals were significantly higher, and serum ferritin levels were significantly lower in migraine patients with RLS compared to those without RLS (p = 0.05, p = 0.028, p = 0.02, and p = 0.038, respectively). Our study suggests that the frequency of RLS is higher in pediatric migraine and TTH patients compared to controls. Therefore, pediatric headache patients should be questioned about the presence of RLS, as this co-occurrence may lead to more frequent accompanying migrainous symptoms and sleep disturbances.

Reliability and validity of the Turkish translation of the beliefs about medicines questionnaire (BMQ-T) in patients with Behçet's disease.

OBJECTIVES: The aim of this study was to evaluate the reliability and validity of the Turkish translation of the Beliefs about Medicines Questionnaire (BMQ-T, ©Prof. Rob Horne) for patients with Behçet's disease. METHODS: This methodological study enrolled a sample of 125 patients. The scale was adapted to Turkish through a process including translation, comparison with versions in other languages, back translation, and pretesting. Construct validity was evaluated by factor analysis. Medication adherence evaluated as poor, moderate and good according to the Morisky Medication Adherence Scale (MMAS). BMQ-T scores compared along medication adherence status groups. RESULTS: In our study, as in the original scale, the factor analysis confirmed that the BMQ-T had a four-factor structure explaining 54.73% of the total variance. The BMQ-T had acceptable internal consistency (Cronbach's alpha coefficient: Specific Necessity=.812; Specific Concerns=.672; General Harm=.677; General Overuse=.656), adequate test-retest reliability (intraclass correlation coefficients: Specific Necessity=.715; Specific Concerns=.680; General Harm=.678; General Overuse=.327). Specific Necessity and Specific Concerns scores were significantly different between medication adherence status groups. CONCLUSIONS: The psychometric properties of the BMQ-T were consistent with those reported in the original study. The BMQ-T was found to be a valid and reliable tool for evaluating beliefs about medicines in patients with Behçet's disease.

A patient-reported outcome measures-based composite index (RAPID3) for the assessment of disease activity in ankylosing spondylitis.

A single questionnaire regarding to disease activity for all rheumatic diseases may present advantages to introduce quantitative measurement into routine care. The aim of this study was to evaluate the correlation of routine assessment of patient index data 3 (RAPID3) with Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Disease Activity Score (ASDAS). A total of 341 consecutive AS patients who met the modified New York classification criteria were included. All patients completed BASDAI and RAPID3 at each visit, and their physicians completed physician global assessment. ASDASs were calculated using defined formulas. Proposed RAPID3 severity categories were compared to BASDAI and ASDAS categories. Spearman's rho correlation test and kappa statistics were used to analyze statistical significance. The median age of AS patients was 34.0 (21.0-69.0) years and the median disease duration 10.0 (2.0-35.0) years. Median scores for RAPID3, BASDAI, ASDAS-CRP, and ASDAS-ESR were 13.0 (0.0-27.3), 4.7 (0.0-9.7), 3.0 (0.4-5.8), and 2.5 (0.5-6.3), respectively. RAPID3 was strongly correlated with BASDAI and ASDAS-ESR (r = 0.842, r = 0.815; p < 0.001, respectively). Among the 209 patients with high disease activity according to BASDAI, 83.3 % had high or moderate severity according to RAPID3 (kappa 0.693; p < 0.001). Among the 133 patients with moderate, high, and very high disease activity on ASDAS-CRP, 91.7 % had high or moderate severity according to RAPID3 (kappa 0.548; p < 0.001). RAPID3 is as informative as BASDAI and ASDAS in our cohort of AS patients. We therefore suggest that RAPID3 may be used to assess the patient status quantitatively in AS patients, as part of routine care.

Thoughts and perceptions of ankylosing spondylitis patients with regard to TNF inhibitors.

The risk of infections and malignancies is the major area of concern with anti-tumor necrosis factor (anti-TNF) agents. The aim of this study was to investigate patients' views about their treatments and the factors that influence patients' treatment decisions concerning the use of anti-TNF-α drugs. This descriptive study was conducted in a single rheumatology unit. Patients using anti-TNF-α drugs for at least 3 months were included. Patients' thoughts and perceptions about their treatment were evaluated using a questionnaire. A total of 101 (94.1% male) patients were recruited. The patients described their feelings as hopeful, worried, happy, scared, desperate, and hopeless, with the order decreasing beginning with the first. Hope for healing and an expectation of increased quality of life were the most significant determinants for acceptance of treatment. After the drug information was given, patients described their feelings as follows: increase in anxiety, psychologically wearisome, and worrying about their condition worsening in the future. After anti-TNF-α treatment, patients described their experience as follows: "the most effective medicine that I have ever used," "it saved my life," "control procedures that were carried out before the treatment and once every 3 months after the treatment were essential," "I feel myself safe with these controls," and "I advised other people." This study, to our knowledge, is the first to evaluate the attitudes of patients concerning anti-TNF-α drugs from the stage of informed consent to the post-experience stage. We found that standard consent forms caused an increase in the level of anxiety among new users of anti-TNF-α drugs, although the aim was the exact opposite. The reasons for acceptance were the hope for healing, reliance on physicians, and advice of other patients. Most patients accepted follow-up control procedures, which aimed to diagnose adverse effects early.

Coping strategies for activities of daily living in women whose hands affected by systemic sclerosis.

AIMS AND OBJECTIVES: To determine the challenges experienced by women with systemic sclerosis, whose hands affected, while performing activities of daily living and their coping strategies. BACKGROUND: Many of the patients with systemic sclerosis experience difficulties in performing daily activities. One of the most important reasons for that is the impaired hand function due to their diseases. DESIGN: A descriptive cross-sectional design was conducted and questionnaire was used in this study. METHODS: The study was performed in a Rheumatology Department at a tertiary-care hospital in Turkey between April 2010-December 2011. Nineteen patients with systemic sclerosis with hand involvement were enrolled in this study. The data were collected by using both a demographic data form and an Evaluation of Daily Activity Questionnaire. RESULTS: According to Evaluation of Daily Activity Questionnaire, the most scored dimension that patients can do with much difficulty was 'eating' and the dimension that patients unable to do was 'washing/clothes care'. In 'eating' dimension, the most difficult activities were 'opening glass jar', 'opening juice bottle' and 'opening bottle' that requiring the movement of rotation. Their coping strategies for these activities were as follows: try to open with a towel, try to remove the edge of the palm with a knife, use the hand palm and help from someone else (spouse, neighbour, etc.). In 'washing/clothes care' dimension, the most difficult activities were 'turning up hem of a skirt', 'washing up in bowl' and 'cutting out material'. For these activities, they use some coping strategies such as getting help from tailor, washing in the machine instead of hand washing. CONCLUSION: This study demonstrates that impaired hand function affects the daily life activities of patients with systemic sclerosis, and patients have developed some coping strategies to overcome these difficulties. RELEVANCE TO CLINICAL PRACTICE: The coping strategies used by patients can be helpful for the other patients with systemic sclerosis.

Selective adsorption of single and binary dyestuffs by citrus peel: Characterization, and adsorption performance.

The powdered citrus peel, which has been replaced with sodium hydroxide, was used in this study to test how well methylene blue and reactive black 5 dyestuff absorbed one or both. To find out about the texture and surface chemistry of modified citrus peel, Fourier transform infrared spectroscopy and scanning electron microscope analyses were carried out. Fourier transform infrared spectroscopy data revealed the presence of amphoteric radicals on the modified citrus peel surface, indicating the effective adsorption of methylene blue and reactive black 5. Many parameters affecting the batch adsorption process, such as modified citrus peel dose (0.1-0.5 g), pH (2-10), time (20-80 min), stirring speed (60-180 rpm), and temperature (20-45 °C), were studied. It is seen that the physical effect is at the forefront, homogeneous monolayer adsorption occurs, and the process fits the Langmuir and pseudo first order models for dyestuffs. Thermodynamic modeling showed that the adsorption of methylene blue and reactive black 5 was spontaneous and endothermic. At pH 2, an adsorption capacity of 0.67 mg/g and a removal efficiency of 66.86% were achieved for reactive black 5. For methylene blue at pH 6, the adsorption capacity was 4.34 mg/g, and the decolorization rate was 87%. The decreases in the removal rates of dyestuffs in the binary system indicate that they are affected by their simultaneous presence in the solution. The results proved that modified citrus peel can be useful for dyestuff removal in single or binary systems, although the removal capacity of modified citrus peel is highly dependent on methylene blue and reactive black 5.

Surface defects due to bacterial residue on shrimp shell.

The changes in the surface chemistry and morphological structure of chitin forms obtained from shrimp shells (ShpS) with and without microorganisms were evaluated. Total mesophilic aerobic bacteria (TMAB), estimated Pseudomonas spp. and Enterococcus spp. were counted in Shp-S by classical cultural counting on agar medium, where the counts were 6.56 ± 0.09, 6.30 ± 0.12, and 3.15 ± 0.03 CFU/g, respectively. Fourier Transform Infrared (FTIR) Spectroscopy and Scanning Electron Microscopy (SEM)/Energy dispersed X-ray (EDX) were used to assess the surface chemistry/functional groups and morphological structure for ChTfree (non-microorganism), and ChTmo (with microorganisms). ChTfree FTIR spectra presented a detailed chitin structure by OH, NH, and CO stretching vibrations, whereas specific peaks of chitin could not be detected in ChTmo. Major differences were also found in SEM analysis for ChTfree and ChTmo. ChTfree had a flat, prominent micropore, partially homogeneous structure, while ChTmo had a layered, heterogeneous, complex dense fibrous, and lost pores form. The degree of deacetylation was calculated for ChTfree and ChTmo according to FTIR and EDX data. The results suggest that the degree of deacetylation decreases in the presence of microorganisms, affecting the production of beneficial components negatively. The findings were also supported by the molecular docking model.

Patient-driven assessment of disease activity in Behçet's syndrome: cross-cultural adaptation, reliability and validity of the Turkish version of the Behçet's Syndrome Activity Score.

OBJECTIVES: The Behçet's Syndrome Activity Score (BSAS) is the first patient reported outcome measure developed to assess the global disease activity in patients with Behçet's syndrome (BS). We aimed to evaluate the reliability and validity of the Turkish version of BSAS for measuring disease activity in BS. We further investigated the performance of Routine Assessment of Patient Index Data (RAPID)3, a patient-reported index originally developed for rheumatoid arthritis, in BS patients. METHODS: Patients seen consecutively at a tertiary Rheumatology Centre were requested to complete BSAS and multidimensional health assessment questionnaire (MDHAQ). Besides, all attending physicians filled the Behçet's Disease Current Activity Form (BDCAF). Descriptive statistics and Pearson correlation coefficients were calculated accordingly for the reliability and validity assessments of BSAS. RESULTS: A total of 104 patients completed all three assessments. The test-retest reliability of BSAS has a good level (ICC=0.84, 95% CI [0.69-0.94]). The mean scores for BSAS, BDCAF and RAPID3 were 39±20.8, 3.2±1.4 and 9.2±5.6, respectively. BSAS was correlated with BDCAF moderately (r=0.587), while it was moderately correlated with RAPID3 (r=0.648). The correlation between the RAPID3 and BDCAF was moderate (r=0.403), but lower as compared to the correlations between the other instruments. CONCLUSIONS: We found that the BSAS has modest correlation with BDCAF and is a reliable and valid patient reported measure of disease activity that can be used to assess patients with BS. An outcome score composed of only patient-derived observations may have the additional advantage of being easier to use in a routine care setting. Demonstration of a moderate level of correlation between RAPID3 and BDCAF (close to the level of weak relationship), suggests that RAPID3 likely needs more investigations before recommending its use in BS.

The expression of transmembrane and soluble CXCL16 and the relation with interferon-alpha secretion in patients with Behçet's disease.

OBJECTIVES: CXCL16 is a member of CXC chemokine, which is synthesised in plasmacytoid dendritic cell as a transmembrane molecule. Transmembrane CXCL16 on plasmacytoid dendritic cell plays a role in binding, uptaking and accumulation of CpG D ODN in early endosomes rather then lysosomal vesicles, thereby causing a high level of interferon-alpha secretion. Previously, we disclosed pronounced interferon-alpha production from these cells in patients with Behçet's disease. The aim of this study was to investigate the relation between the secretion of IFN-α and the expression of CXCL16 on surface of plasmacytoid dendritic cell from patients with Behçet's disease, and compare it with patients with ankylosing spondylitis and healthy controls. METHODS: The study population consisted of 73 cases (35 with Behçet's disease, 19 with ankylosing spondylitis and 19 controls). We investigated the expression of CXCL16 on surface of plasmacytoid dendritic cells by flow cytometry, and the serum levels of IFN-α and CXCL16 with ELISA. RESULTS: Serum levels of IFN-α in patients with Behçet's disease were significantly higher than the controls (p=0.009), and than patients with ankylosing spondylitis, but not statistically significant (p=0.124). Serum levels of CXCL16 in patients with Behçet's disease and patients with ankylosing spondylitis were significantly higher than controls (p=0.009, p=0.003, respectively). We found no difference in the percentage and MFI of plasmacytoid dendritic cells and CD123+CXCL16+ cells determined by flow cytometry among the study and control groups. In patients with Behçet's disease, a positive correlation was found between the percentage of plasmacytoid dendritic cells and CD123+CXCL16+ cells (p<0.001). Furthermore, there was also a positive correlation between the percentage of plasmacytoid dendritic cells and serum levels of CXCL16 in patients with ankylosing spondylitis (p=0.001). In addition, there was a positive correlation between the percentage of CD123+CXCL16+ cells and serum levels of IFN-α in Behçet's disease group (p=0.034). We could not find any significant difference in other comparisons. CONCLUSIONS: We suggested that the expression of transmembrane CXCL16 on surface of plasmacytoid dendritic cell might contribute to high serum IFN-α levels seen in patients with BD.

Clinical significance of coexisting antitopoisomerase I and anticentromere antibodies in patients with systemic sclerosis: a EUSTAR group-based study.

OBJECTIVES: To determine the clinical characteristics of simultaneous occurrence of antitopoisomerase (ATA) and anticentromere (ACA) autoantibodies in systemic sclerosis (SSc). METHODS: Data of patients (n=4,687) fulfilling the ACR criteria for SSc and followed in the EULAR Scleroderma Trials and Research (EUSTAR) cohort were analysed. Sera from patients with simultaneous ATA and ACA were reanalyzed centrally by indirect immunofluorescence, enzyme immunoassay, and immunoblot to confirm antibody status. RESULTS: A total of 29 patients (0.6%) had been documented double-positive for both ATA and ACA in the EUSTAR database. Sera of 14 cases were available for central analysis, of which 8 were confirmed to unequivocally contain both antibodies. The double-positive patients were on average 52.4 years of age, 87.5% were female, and 62.5% had diffuse cutaneous (dc) SSc. Compared with matched ACA single-positive disease, cutaneous and visceral complications were more prevalent in double-positive cases, but this prevalence did not differ significantly in comparison to ATA single-positives. CONCLUSIONS: Coexistence of ATA and ACA can be found at low prevalence in SSc. The clinical features of double-positive patients are not clearly dissimilar to those of patients harbouring only ATA. The data do not support a direct involvement of these antibodies in the pathogenesis of established SSc, but may lack statistical power.

Relationship of ultrasonographic findings with synovial angiogenesis modulators in different forms of knee arthritides.

Angiogenesis is controlled by a variety of angiogenesis stimulators and inhibitors. The increased power Doppler (PD) signals determined by ultrasonography is an indirect marker of synovial vascularity in arthritis. We aimed to investigate relationship between ultrasonographic findings and synovial angiogenesis modulators. Thirteen Behcet's disease (BD), 15 spondyloarthropathy, 21 rheumatoid arthritis (RA), and 15 osteoarthritis (OA) patients with knee arthritis were included. Cumulative effusion, synovial hypertrophy, and PD signal scores were calculated in arthritic joints. In synovial fluid samples, angiogenesis inhibitors (angiostatin, thrombospondin-1, and endostatin) and stimulators [bFGF (basic fibroblast growth factor), angiopoietin-1] were studied. The comparisons between groups were made by Kruskal-Wallis test, and correlation analysis was calculated with Pearson and Spearman tests. Effusion scores were significantly higher in inflammatory arthritis than in OA. Synovial hypertrophy scores were higher in RA and spondylarthritis than in OA and BD. PD scores were not different between the groups. Synovial angiostatin and bFGF levels were significantly higher in patients with inflammatory arthritis than in OA. Cumulative effusion scores were positively correlated with angiopoietin-1, angiostatin, and bFGF and negatively correlated with thrombospondin-1 levels. Synovial hypertrophy scores were positively correlated with angiostatin and bFGF levels and negatively correlated with thrombospondin-1. No correlation was found between PD scores and modulators of angiogenesis. In large joints like knee, detecting PD signals alone was not sufficient to assess the angiogenesis. However, cumulative activity scores were positively correlated with angiogenesis stimulators. Therefore, when investigating the angiogenesis, PD technique should be added to gray-scale examinations.

A polymorphism in ERAP1 is associated with susceptibility to ankylosing spondylitis in a Turkish population.

We assessed the role played by the ERAP1 gene in Turkish patients with ankylosing spondylitis (AS) in terms of disease susceptibility, clinical manifestations, and disease severity. We included 150 consecutive AS patients who met the modified New York classification criteria and 150 healthy controls. We documented the presence of 10 ERAP1 single-nucleotide polymorphisms (SNPs) and HLA-B27 in these patients. ERAP1 SNPs were genotyped using competitive allele-specific polymerase chain reaction. Differences between genotype and allele frequencies were compared using the Pearson's Chi-square test. The associations between ERAP1 SNPs, on the one hand, and with disease severity and clinical findings, on the other, were determined. One SNP, rs26653, was significantly associated with AS susceptibility (OR 1.609, 95% CI 1.163-2.226; p = 0.004). The population-attributable risk of possession of the rs26653 SNP allele was 23.4%. No relationship was noted between HLA-B27 positivity and the distribution of rs26653 genotype frequency. No associations were seen between disease severity measures and clinical manifestations of AS. In summary, an ERAP1 polymorphism was associated with AS in a Turkish population. The contributions of HLA-B27 and the rs26653 SNP to AS pathogenesis appear to be independent.

Value of DWI in visual assessment of activity of sacroiliitis in longstanding ankylosing spondylitis patients.

OBJECTIVE: To test contrast to noise ratios (CNRs) of both diffusion-weighted (DW) images and contrast enhanced images in terms of the visual assessment of activity in sacroiliitis of ankylosing spondylitis (AS) patients. MATERIALS AND METHODS: The study included 21 patients with AS. All patients were examined with STIR, FST1/Gd and DWI (b = 0,600). A total of 54 hyperintense lesions on STIR were noted in their sacroiliac joints divided into four quadrants. CNRs were calculated for all of the sequences above. A second group of patients (n = 7) with normal sacroiliac joints (SIJs) served as controls. A total of 56 CNR measurements from apparently normal subchondral bone marrow in this control group were done as well. The differences between scores were tested for significance (SPSS version 17.0) using Wilcoxon's test in which p values lower than 0.01 were considered statistically significant. RESULTS: In the first group with sacroiliitis, mean CNRs for STIR, FST1/Gd, DWI were 32.97, 30.16 and 24.47, respectively. Mean CNRs in the second group with normal SIJs were calculated as 3.52 , 2.99 and 3.96, respectively . There was a statistically significant difference between the CNR measurements of the first and the second group (p = 0.000). Hyperintense lesions on STIR were depicted as "active" in the first group. Except for four lesions that were not included into the study, all of these hyperintense lesions were enhanced after contrast media administration. All of the "active" lesions were observed on DWI as well, at b = 600. No statistically significant difference between CNRs of contrast enhanced images and DWI and of contrast enhanced images and fluid sensitive sequences were found in the first group with sacroiliitis (p > 0.01). CONCLUSION: The CNRs are highest on STIR, followed by contrast enhanced images and DWIs. In terms of DWI and contrast enhanced images, there is no statistically significant difference between these two. Hence, contrast enhanced imaging can be replaced by DWI for visual analysis of active sacroiliitis, which is easy to apply without adverse affects of contrast media.

Use of different food wastes as green biosorbent: isotherm, kinetic, and thermodynamic studies of Pb2.

Lead (Pb2+) can contaminate waters from many sources, especially industrial activities. This heavy metal is an amphoteric, toxic, endocrine-disrupting, bioaccumulative, and carcinogenic pollutant. One of the effective and economical processes used to remove lead from water is adsorption. The fact that the adsorbents used in this method are easily available and will contribute to waste minimization is the primary reason for preference. In this study, the adsorption abilities and surface properties of tea waste (TW), banana peels (BP), almond shells (AS), and eggshells (ES) which are easily available do not need modification and have very high (> 90%) removal efficiencies presented with isotherm, kinetic, and thermodynamic perspectives as detail. The surface structures and elemental distribution of raw adsorbents were revealed with SEM/EDX. Using FTIR analysis, carboxylic (-COOH) and hydroxyl groups (-OH) in the structure of TW, AS, BP, and ES were determined. It was determined that the Pb2+ adsorption kinetics conformed to the pseudo-quadratic model and its isotherm conformed to the Langmuir. The optimum adsorption of Pb2+ was ranked as BP > ES > AS > TW with 100, 68.6, 51.7, and 47.8 mg/g qm, respectively. The fact that the process has negative ΔG° and positive ΔH° values from a thermodynamic point of view indicates that it occurs spontaneously and endothermically. According to the experimental data, the possible adsorption mechanism for Pb2+ has occurred in the form of physisorption (van der Waals, electrostatic attraction) and cooperative adsorption including chemisorption (complexation, ion exchange) processes.

Safety, Tolerability, and Pharmacokinetics of Same-Knee Intra-Articular Injection of Corticosteroid and Lorecivivint Within 7 Days: An Open-Label, Randomized, Parallel-Arm Study.

INTRODUCTION: Knee osteoarthritis (OA) is a common painful disorder. Intra-articular (IA) corticosteroid injections are frequently prescribed to treat knee pain. Lorecivivint (LOR), a novel IA cdc2-Like Kinase (CLK)/Dual-Specificity Tyrosine Phosphorylation-Regulated Kinase (DYRK) inhibitor thought to modulate Wnt and inflammatory pathways, has appeared safe and demonstrated improved patient-reported outcomes compared with placebo. While LOR is proposed for stand-alone use, in clinical practice, providers might administer LOR in close time proximity to IA corticosteroid. This open-label, parallel-arm, healthy volunteer study assessed potential short-term safety, tolerability and pharmacokinetic (PK) interactions between IA LOR and triamcinolone acetonide (TCA) administered 7 days apart. METHODS: Healthy volunteers were randomized to Treatment Sequence 1 (IA 40 mg TCA followed by IA 0.07 mg LOR) or Treatment Sequence 2 (IA 0.07 mg LOR followed by IA 40 mg TCA). Treatment-emergent adverse events (TEAEs) were categorized by "epoch", with epoch 1 spanning from first until second injection, and epoch 2 spanning from second injection until end of study. Plasma PK was assessed pre injection and out to 22 days after to assess PK treatment interaction. RESULTS: A total of 18 TEAEs were reported by 11 (27.5%) of 40 enrolled participants, and there were no serious adverse events. Thirteen TEAEs were reported in Treatment Sequence 1 and five in Treatment Sequence 2, similarly distributed between epochs 1 and 2. In all participants and at all time points, plasma LOR concentrations were below the limit of quantification (0.100 ng/mL). Geometric mean concentrations and PK parameters for TCA were similar between treatment sequences. CONCLUSION: No safety signals were observed. There were no quantifiable plasma concentrations of LOR in either Treatment Sequence. The PK of TCA was unaffected by previous LOR injection. These results suggest that IA administration of LOR and TCA in close time proximity is unlikely to pose a safety concern. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT04598542.

Knee osteoarthritis (OA) is a common disorder characterized by pain and loss of function. This clinical trial tested if two different treatments for OA injected into the same knee 1 week apart would impact the safety or exposure of either treatment. The treatments evaluated were an injection of a corticosteroid, triamcinolone acetonide, and a potential OA treatment in development, lorecivivint, a novel small molecule thought to inhibit inflammation and a biological pathway called the Wnt pathway. The amount of either treatment found in circulation was not different when injected before or after the other treatment. The order of injection did not change the safety profile for either agent, suggesting injection of the two agents 1 week apart is unlikely to pose a safety concern.

Onycho-pachydermatit with extensive bone marrow edema predominant in the metacarpals: a "forme fruste" of POPP?

Psoriatic onycho-pachydermo-osteo/periostitis (POPP) syndrome is a rare form of psoriatic arthritis with a combination of (i) psoriatic onychodystrophy, (ii) connective tissue thickening, and (iii) periostitis of the distal phalanges. The treatment of the condition has generally been reported to be unsatisfactory with the traditional regimes. Here, we describe a case whom we believe is one presentation of POPP with extensive bone marrow edema of metacarpal bones without distinctive periostitis.

Investigation of the veins in patients with Behçet's disease with no known vascular event by Doppler ultrasonography.

In Behçet's disease, deep venous thrombosis occurs primarily in the lower extremities. Total recanalization rate is low, so thrombotic segment could be detected by imaging afterward. For disclosing vein involvement, leg swelling is commonly queried in the history taking in those patients. However, there are no data about the presence of "silent" thrombosis in patients with BD. We aimed at investigating the integrity of venous vessels in BD, without any known vascular event by using Doppler ultrasonography (DU). Patients having past events revealed in the vascular questionnaire or physical findings attributable to vascular disease were excluded. Various degree of venous insufficiency was detected in 74 patients in BD (74%), 24 out of 33 patients (72%) in AS and in 8 out of 34 (25%) in HC group. All were at the lower extremities, and there is no difference in the frequency between BD and AS, while both were significantly higher than in HC (P = 0.001, and 0.004, respectively). Six patients with BD (6%) have chronic venous thrombi at the lower extremities and none in either AS and HC. As a non-invasive method, DU of lower extremities may disclose "silent" thrombosis. Venous insufficiency in those patients should be considered cautiously as an indicator of vein involvement.

Living with scleroderma: patients' perspectives, a phenomenological study.

In this study, it is aimed to determine the daily life experiences of patients on the basis their own way of statement. Sixteen patients with scleroderma were enrolled to this qualitative study. Data were collected using both a demographic data form and a semi-structured interview form. Study was made on individual patient interview by face-to-face manner. Data were evaluated using Colaizzi's phenomenological data analysis method. Data analysis revealed four categories and nine topics. These categories were (1) physical impact of disease, (2) emotional impact of disease, (3) social impact of disease and (4) patient behaviours for the cope with the disease. As emotional impact, patients imply that they have experienced disappointment, hope to get well and have fears about the future. In the physical impact category, tight skin, limitations of hand skills, swelling of the hands and feet, fatigue, swallowing difficulties and deformation of their bodies were the prominent features. In patients with recognizable disease, difficulty to join to social activities increases and eventually leads to isolation. There was also some evidence that patients who have been supported by their family and close relatives seem to be more optimistic about their disease. Most patients are not willing to communicate with other patients, particularly in an advanced stage. Scleroderma patients imply that they experience several difficulties regarding emotional, physical and social aspects. Individual abilities to cope with the disease were much more improved among patients who have a sustained social support. For advanced patients with apparent deformations, an effective social support system should be introduced.
