Effective diagnosis of sacroiliitis in children: evaluating magnetic resonance imaging with the Canadian scoring system. Clin Rheumatol 2024; 43:2125-2131. [PMID: 38702567 DOI: 10.1007/s10067-024-06979-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 04/21/2024] [Accepted: 04/24/2024] [Indexed: 05/06/2024]
Abstract
OBJECTIVES To reveal the differences by comparing the magnetic resonance imaging (MRI) findings of patients with clinically symptomatic sacroiliitis with those undergoing sacroiliac imaging for other reasons using the Canadian Spondyloarthritis Research Consortium-Sacroiliac Inflammatory Scoring System (SPARCC-SIS). METHODS In this retrospective single-center study, sacroiliac MRIs performed between 2017 and 2023 were evaluated from the database. The SPARCC-SIS scoring system is used to evaluate and grade the inflammation of the sacroiliac joints. Mild inflammation is indicated by a score below 24, moderate by a score of 24-48, and severe by a score above 49. Additionally, structural defects of the sacroiliac joint, such as erosion, sclerosis, and ankylosis, were observed. After MRI evaluation, clinically symptomatic (group 1) and non-symptomatic (group 2) patients were divided into two groups. The clinical and laboratory findings of the patients and MRI findings were compared. The patient's age, gender, clinical information from hospital records, acute phase reactants (APRs), and the presence of the Human Leukocyte Antigen (HLA-B27) gene (if applicable) were thoroughly recorded. RESULTS One hundred thirty-six children who performed sacroiliac MRI for any indication were included in the study. The APRs positivity, presence of HLA-B27, and SPARCC scoring system were significantly higher in 24 patients with clinical sacroiliitis (group 1) than in 112 patients without sacroiliitis (group 2). In our study, the most common MRI findings in children were bone marrow edema, capsulitis, synovitis, and erosion, while chronic structural changes such as sclerosis and ankylosing were rare. CONCLUSION In this study, the SPARCC scoring method, which shows the severity of sacroiliac joint inflammation, correlates with the clinical diagnosis of sacroiliitis. In cases with suspected sacroiliitis, except for extraordinary reasons, it can be evaluated with MRI without contrast material and can be graded to guide the clinician in treatment and approach.

The effect of temporomandibular joint dysfunction on the craniocervical mandibular system: A retrospective study. J Oral Rehabil 2024; 51:469-475. [PMID: 37983893 DOI: 10.1111/joor.13622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 05/30/2023] [Accepted: 10/28/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND Temporomandibular disorders are the most common condition affecting the orofacial region, resulting in pain and dysfunction. OBJECTIVE This study aimed to elucidate the ambiguous association between cervical features and temporomandibular disorders by measuring the rotations between the skull-atlas, atlas-axis and mandible-atlas and examining the relationship between these rotations and temporomandibular disorders. METHODS Cone-beam computed tomography (CBCT) images from 176 patients, 97 females and 79 males with an average age of 25.7 years were used in this study. The patients were divided into two groups: those with joint dysfunction (n = 88) and those without (n = 88). The study employed various methods to determine rotations in the skull-atlas, atlas-axis and mandible atlas based on anatomical landmarks and measurements. These methods include the use of specific planes, angles and distances to identify and measure rotation. Data analysis was performed using the TURCOSA statistical software (Turcosa Analytics Ltd Co, Turkey, www.turcosa.com.tr). RESULTS The results showed that the degree of rotation between the skull and the atlas was higher in the TMD group than in the control group (p < .001). Similarly, Atlas-axis rotation was significantly higher in the TMD group (p < .001). However, no significant difference was found between mandible atlas rotations in the two groups (p = .546). The study also found a significant difference between the direction of rotation between the atlas and axis and the direction of mandible atlas rotation (p < .001) as well as between skull and atlas rotations and mandible-atlas rotations (p < .001). CONCLUSION Overall, the study suggests that there is a relationship between the skeletal structures of the cranio-cervico-mandibular system and TMD. Skull-atlas and atlas-axis rotations may play an important role in the aetiology of TMD in individuals with TMD. Therefore, it is important to evaluate rotations in the skull-atlas-axis region for the treatment of TMD.

Towards a standardized program of transitional care for adolescents with juvenile idiopathic arthritis for Turkey: a national survey study. Pediatr Rheumatol Online J 2024; 22:7. [PMID: 38167070 PMCID: PMC10762787 DOI: 10.1186/s12969-023-00943-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Accepted: 12/09/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is a prevalent childhood chronic arthritis, often persisting into adulthood. Effective transitional care becomes crucial as these patients transition from pediatric to adult healthcare systems. Despite the concept of transitional care being recognized, its real-world implementation remains inadequately explored. This study aims to evaluate the thoughts and practices of healthcare providers regarding transitional care for JIA patients. METHODS A cross-sectional survey was conducted among pediatric and adult rheumatologists in Turkey. Based on the American Academy of Pediatrics' six core elements of transitional care, the survey included 86 questions. The respondents' demographic data, attitudes towards transitional care, and practical implementation were assessed. RESULTS The survey included 48 rheumatologists, with 43.7% having a transition clinic. The main barriers to establishing transition programs were the absence of adult rheumatologists, lack of time, and financial constraints. Only 23.8% had a multidisciplinary team for transition care. Participants agreed on the importance of coordination and cooperation between pediatric and adult healthcare services. The timing of the transition process varied, with no consensus on when to initiate or complete it. Participants advocated for validated questionnaires adapted to local conditions to assess transition readiness. CONCLUSIONS The study sheds light on the challenges and perspectives surrounding transitional care for JIA patients in Turkey. Despite recognized needs and intentions, practical implementation remains limited due to various barriers. Cultural factors and resource constraints affect the transition process. While acknowledging the existing shortcomings, the research serves as a ground for further efforts to improve transitional care and ensure better outcomes for JIA patients transitioning into adulthood.

Clin Rheumatol 2024; 43:407-413. [PMID: 37926798 DOI: 10.1007/s10067-023-06802-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 10/19/2023] [Accepted: 10/20/2023] [Indexed: 11/07/2023]
Abstract
AIM The aim of this study was to investigate the frequency and type of FMF-associated inflammatory diseases in a large FMF pediatric patients and to compare them to those FMF patients without concomitant inflammatory diseases. MATERIALS AND METHODS Familial Mediterranean fever patients enrolled in the Pediatric Rheumatology Academy (PeRA)-Research Group (RG) were included. The patients were divided into two groups according to concomitant inflammatory disease as FMF patients who had a concomitant inflammatory disease (group 1) and FMF patients who did not have a concomitant inflammatory disease (group 1). The clinical findings and treatments were compared between the two groups. RESULTS The study group comprised 3475 patients with FMF. There were 294 patients (8.5%) in group 1 and 3181 patients (91.5%) in group 2. Juvenile idiopathic arthritis (n = 136) was the most common accompanying inflammatory disease. Arthritis, M694V homozygosity, and the need for biological therapy were more frequently observed in Group 1 (p < 0.05). Fever and abdominal pain were more frequently detected in Group 2 (p < 0.05). FMF patients with concomitant inflammatory diseas more frequently demonstrated colchicine resistance. There were no significant differences in the median attack frequency, chest pain, amyloidosis, erysipelas-like erythema, or family history of FMF between the two patient groups. CONCLUSION To the best of our knowledge, this is the largest pediatric cohort reviewed to date. FMF patients may have different clinical profiles and colchicine responses if they have with concomitant inflammatory diseases. Key points • FMF is associated with some inflammatory comorbidities diseases. • To the best of our knowledge, this is the largest cohort evlauated pediatric FMF associated inflammatory comorbidities diseases reviewed to date.

Evaluation of childhood malignancies presenting with musculoskeletal manifestations from two different divisions: a multicenter study. Turk J Pediatr 2024; 66:81-89. [PMID: 38523382 DOI: 10.24953/turkjped.2023.446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/26/2024]
Abstract
BACKGROUND The aim of the study was to evaluate the approaches of pediatric rheumatologists and pediatric hematologists to patients with similar musculoskeletal (MSK) complaints and to highlight the differences that general pediatricians should consider when referring patients to these specialties. METHODS This is a cross-sectional study involving the patients who applied to pediatric rheumatology centers with MSK complaints and were diagnosed with malignancy, as well as patients who were followed up in pediatric hematology centers with a malignancy diagnosis, and had MSK complaints at the time of admission. RESULTS A total of 142 patients were enrolled in the study. Of these patients, 83 (58.4%) applied to pediatric rheumatology centers, and 59 (41.6%) applied to pediatric hematology centers. Acute lymphoblastic leukemia (ALL) was the most common diagnosis among the patients who applied to both centers, with 80 cases (56.3%). The median age of diagnosis was 87 (interquartile range, IQR: 48-140) months. The most common preliminary diagnosis in pediatric rheumatology centers was juvenile idiopathic arthritis (JIA), with 37 cases (44.5%). MSK involvement was mainly seen as arthralgia, and bone pain. While arthralgia (92.7%) was the most common complaint in rheumatology centers, bone pain (88.1%) was more common in hematology centers. The most frequently involved joints were the knee (62.9%), ankle (25.9%), hip (25%), and wrist (14%). The most common laboratory abnormalities were high lactate dehydrogenase (LDH), high C-reactive protein (CRP), anemia, and high erythrocyte sedimentation rate (ESR). Thrombocytopenia, neutropenia, and high LDH were statistically significantly more frequent in patients admitted to hematology centers than in patients admitted to rheumatology centers (p < 0.001, p=0.014, p=0.028, respectively). Patients who applied to rheumatology clinics were found to have statistically significantly higher CRP levels (p=0.032). CONCLUSIONS Malignancies may present with only MSK system complaints in childhood. Therefore, malignancies should be included in the differential diagnosis of patients presenting with MSK complaints.

PREDICT-crFMF score: A novel model for predicting colchicine resistance in children with familial Mediterranean fever. Mod Rheumatol 2023; 34:220-225. [PMID: 36680425 DOI: 10.1093/mr/road008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 10/20/2022] [Accepted: 01/13/2023] [Indexed: 01/22/2023]
Abstract
OBJECTIVES To develop a novel scoring system to predict colchicine resistance in Familial Mediterranean fever (FMF) based on the initial features of the patients. METHODS The medical records of patients were analyzed prior to the initiation of colchicine. After generating a predictive score in the initial cohort, it was applied to an independent cohort for external validation of effectiveness and reliability. RESULTS Among 1418 patients with FMF, 56 (3.9%) were colchicine resistant (cr) and 1312 (96.1%) were colchicine responsive. Recurrent arthritis (4 points), protracted febrile myalgia (8 points), erysipelas-like erythema (2 points), exertional leg pain (2 points), and carrying M694V homozygous mutation (4 points) were determined as the parameters for predicting cr-FMF in the logistic regression model. The cut-off value of 9 was 87% sensitive and 82% specific to foresee the risk of cr-FMF in the receiver operating characteristic. Validation of the scoring system with an independent group (cr-FMF = 107, colchicine responsive = 1935) revealed that the cut-off value was 82% sensitive and 79% specific to identify the risk of cr-FMF. CONCLUSIONS By constructing this reliable and predictor tool, we enunciate that predicting cr-FMF at the initiation of the disease and interfering timely before the emergence of complications will be possible.

Effect of systemic atorvastatin on bone regeneration in critical-sized defects in hyperlipidemia: an experimental study. Int J Implant Dent 2023; 9:50. [PMID: 38097856 PMCID: PMC10721777 DOI: 10.1186/s40729-023-00508-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Accepted: 10/18/2023] [Indexed: 12/17/2023] Open
Abstract
PURPOSE Hypocholesterolemic medications similar to atorvastatin are efficient in lowering blood lipid levels; however, compared to other medications in the statin family, their impact on bone metabolism is claimed to be insufficient. The impact of atorvastatin on bone regeneration in dental implantology in individuals with hyperlipidemia who received atorvastatin in the clinic is doubtful. METHODS In the study, 16 male New Zealand rabbits of 6 months were used. All rabbits were fed a high-cholesterol diet for 8 weeks, and hyperlipidemia was created. It was confirmed that the total cholesterol level in rabbits was above 105 mg/dl. A critical-sized defect was created in the mandible. The defect was closed with xenograft and membrane. Oral 10 mg/kg atorvastatin was started in the experimental group, and no drug was administered in the control group. At 16th week, animals were sacrificed. For histomorphological examination, the new bone area, osteoclast, and osteoblast activities were evaluated. RESULTS While new bone area (45,924 µm2, p < 0.001) and AP intensities (105.645 ± 16.727, p = 0.006) were higher in the atorvastatin group than in the control group, TRAP intensities in the control group (82.192 ± 5.346, p = 0.021) were higher than that in the atorvastatin group. CONCLUSIONS It has been found that high blood lipid levels will adversely affect bone graft healing and the use of systemic atorvastatin contributes to bone healing. Clinicians should pay attention to the selection of surgical materials, considering the importance of questioning drug use in their patients and the risks in cases of non-use.

Abstract
BACKGROUND There is no clear data on the optimal duration of treatment with anti-interleukin-1 drugs in colchicine-resistant familial Mediterranean fever patients, as well as on the dose interval. This study aimed to assess patients whose canakinumab dose interval was adjusted according to a specific protocol, with the objective of evaluating the effectiveness of implementing this protocol for the patient care. METHODS The files of 45 patients whose canakinumab treatment interval was opened with a standard protocol previously determined by the Delphi method were retrospectively reviewed. RESULTS Canakinumab treatment was initiated once a month for all patients. In the sixth month of canakinumab treatment, a dose interval extension was introduced; however, 7 patients (15.5%) experienced an attack, and consequently, no further interval extension was administered to them. For 29 patients, the dose interval was successfully extended to once every three months, as they remained attack-free for a year after the first interval extension. Nine patients continued receiving the drug every 2 months, as they had not yet completed one year since the first extension. The study found no significant correlation between experiencing an attack during the dose interval extension protocol and the number, duration of attacks, or autoinflammatory diseases activity index score. CONCLUSION Extending treatment intervals with canakinumab in colchicine-resistant familial Mediterranean fever shows promise for favorable outcomes.

Remission rates and risk factors for relapse in pediatric morphea: a multicenter retrospective study of Pediatric Rheumatology Academy (PeRA)-Research Group (RG). Clin Rheumatol 2023; 42:2855-2860. [PMID: 37378874 DOI: 10.1007/s10067-023-06677-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 05/27/2023] [Accepted: 06/15/2023] [Indexed: 06/29/2023]
Abstract
AIM Morphea, also known as localized scleroderma, is an immune-mediated disease and the most common form of scleroderma in children. It is a localized sclerosing disease of the skin, but can also involve such adjacent tissues as the fascia, muscle, bone, and underlying tissues. This multicenter study aimed to evaluate Turkish pediatric morphea patients, regarding demographics, treatments, and response to treatment. MATERIALS AND METHODS The study was performed by the Pediatric Rheumatology Academy and included pediatric morphea patients from 6 Turkish pediatric rheumatology centers who were followed up for ≥6 months. Demographic, clinical, and laboratory findings and treatment modalities were analyzed. The patients were divided into 3 groups according to treatment response, as follows: group 1: topical treatment response, group 2: methotrexate response, and group 3: methotrexate resistance. Clinical findings were compared between the 3 groups. RESULTS The study included 76 patients, of which 53 (69.7%) were female. Mean age at diagnosis of morphea was 9.7 ± 4.3 years and mean duration of follow-up was 3.2 ± 2.9 years. Linear morphea was the most common form, accounting for 43.4% (n = 33) of the patients. Extracutaneous features were noted in 17 patients (22.4%) and anti-nuclear antibody positivity was noted in 32 (42.1%). In all, 14.4% of the patients received topical treatment only, whereas 86.6% received both topical and systemic treatment. The methotrexate response rate was 76.9% in the patients that received systemic immunosuppressive therapy. The overall relapse rate while under treatment was 19.7%. CONCLUSION In this study, most of the pediatric morphea patients responded well to methotrexate. Bilateral lesions were more common in the methotrexate-resistant group. Multiple involvement, and bilateral lesions, were more common in relapsed patients than in non-relapsed patients. Key points • Most of the pediatric morphea patients respond well to MTX. • Multiple involvement, and bilateral involvement, were more common in relapsed patients than in non-relapsed patients. • Presence of extracutaneous findings in patients increased relapse rate 5.7 times.

Anti-inflammatory and pro-regenerative effects of a monoterpene glycoside on experimental periodontitis in a rat model of diabetes. J Periodontal Res 2023; 58:932-938. [PMID: 37340760 DOI: 10.1111/jre.13151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 05/17/2023] [Accepted: 06/06/2023] [Indexed: 06/22/2023]
Abstract
OBJECTIVE Paeoniflorin (Pae) is a monoterpene glycoside with immune-regulatory effects. Several studies have already demonstrated the impact of Pae on periodontitis, but its effect on diabetic periodontitis is unclear. In this study, our aim was to test the hypothesis that Pae had a strong anti-inflammatory effect that prevented bone loss in diabetic periodontitis. METHODS Thirty male Wistar albino rats were randomly divided into control (healthy, n = 10), periodontitis (PD) + diabetes (DM; n = 10), and PD + DM + Pae (n = 10) groups. Ligature-induced periodontitis was created by placing 4-0 silk ligatures around the lower first molars on both sides of the mandibulae. Experimental DM was created via an injection of 50 mg/kg and streptozotocin (STZ). Hyperglycemia was confirmed by the blood glucose levels of rats (>300 mg/dL). The bone mineral density (BMD), trabecular number, trabecular thickness, and bone loss were measured by micro-CT. The expression levels of IL-1β, IL-6, and TNF-α were measured in tissue homogenates by ELISA. RESULTS The PD + DM + Pae group had significantly less alveolar crest resorption when compared to the PD + DM group. There was also a significant difference between the PD + DM + Pae group compared to PD + DM group in trabecular thickness, BMD, and the number of trabeculae. Pae application led to a statistically significant decrease in IL-1β, IL-6, and TNF-α levels in diabetic periodontitis. CONCLUSION Systemic application of Pae suppressed inflammation caused by PD and DM, leading to reduced bone loss and enhanced bone quality.

Abstract
The inferior alveolar nerve can be damaged during dental procedures, leading to symptoms, such as tingling, numbness, and reduced quality of life. Recovery depends on factors such as medications, surgery, and photobiomodulation therapy. Photobiomodulation therapy has shown the potential to improve nerve function and reduce regeneration time; however, there is no standard treatment protocol yet. This study aimed to examine the effect of diode lasers on nerve regeneration in patients with axonetmesis injuries. In this experiment on animals, Wistar rats' damaged sensory systems were treated with lasers to restore them. Animals were randomly divided into six groups: a sham group, a control group, and four laser treatment groups(1st group: performed every day, 10 sessions; 2nd group: performed every 2 days, 10 sessions; 3rd group: performed every day, 20 sessions; and 4th group: performed every 2 days, 20 sessions). Sensory function was determined using the Semmes-Weinstein monofilament test, which was repeated after the surgical procedure. The results showed that the 20-session group had the best improvement, most closely resembling the group without sensory test damage. The histomorphometric results showed that the number of axons was significantly lower in the group that received 10 daily sessions and in the control group than in the undamaged nerve. Axon diameter was lower in all groups than in the sham group. In conclusion, the remarkable aspect of this study is that consecutive-day 20-session laser treatment showed better improvement than the over-the-day 20-session treatment protocol.

Abstract
This study aimed to determine the effects of fat type (sheep tail fat (STF) and beef fat (BF)), fat levels (10, 20, or 30%), and cooking time (0, 2, 4, and 6 min, dry heat cooking at 180 °C) on the carboxymethyl lysine (CML) content in meatballs. pH, thiobarbituric acid reactive substance (TBARS), and volatile compound analyses were also performed on the samples. The use of STF and the fat level had no significant effect on the pH value. The highest TBARS value was observed with the combination of a 30% fat level and STF. CML was not affected by the fat level. The highest CML content was determined in meatballs with STF at a cooking time of 6 min. In the samples cooked for 2 min, no significant difference was observed between STF and BF in terms of the CML content. STF generally increased the abundance of aldehydes. Aldehydes were also affected by the fat level and cooking time. A PCA provided a good distinction between groups containing STF and BF regardless of the fat level or cooking time. Pentanal, octanal, 2,4-decadienal, hexanal, and heptanal were positively correlated with CML.

Abstract
OBJECTIVE Rheumatoid factor (RF)-positive polyarthritis is the least common type of juvenile idiopathic arthritis (JIA). Functional disability in RF-positive polyarthritis patients is much more severe than in patients with other subtypes; but data on this subtype alone is limited. This study aimed to analyze clinical features, long-term follow-up, treatment response, and remission status in a large multicenter cohort of RF-positive polyarthritis patients. METHODS This retrospective study included RF-positive polyarthritis patients that were followed up for ≥ 6 months between 2017 and 2022 by the Pediatric Rheumatology Academy (PeRA)-Research Group (RG). Data on patient demographics, clinical and laboratory characteristics were obtained from medical charts. JIA treatments and duration of treatment were also recorded. The patients were divided into 2 groups based on methotrexate (MTX) response, as follows: group 1: MTX responsive, group 2: MTX unresponsive. Clinical and laboratory findings were compared between the 2 groups. RESULTS The study included 56 (45 female and 11 male) patients. The median age at onset of RF-positive polyarthritis was 13.2 years [(interquartile range) (IQR): 9.0-15.0 years] and the median duration of follow-up was 41.5 months (IQR: 19.5-75.7 months). Symmetrical arthritis affecting the metacarpophalangeal and proximal interphalangeal joints of the hands was commonly observed. Subcutaneous MTX was the preferred initial treatment; however, it was ineffective in 39 (69.6%) of the patients. Of 25 patients followed for 24 months, 56% still had active disease at 24 months. CONCLUSION During 2 years of treatment, 44% of RF-positive polyarthritis patients have inactive disease, and they should be considered as a distinct and important clinical entity requiring aggressive and early treatment.

[PMID: 36858168 DOI: 10.1016/j.jbspin.2023.105559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 02/07/2023] [Accepted: 02/13/2023] [Indexed: 03/02/2023]
Abstract
INTRODUCTION Neuropsychiatric (NP) involvement is a restricted area in juvenile-onset systemic lupus erythematosus (jSLE). AIM To investigate the prevalence, demographic and clinical features, and outcomes of the neurological involvement in the Turkish jSLE population. METHODS This study was based upon 24 referral centers' SLE cohorts, multicenter and multidisciplinary network in Turkey. Patient data were collected by a case report form which was standardized for NP definitions according to American Collage of Rheumatology (ACR). Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) neuropsychiatric part was used to determine NP damage. Variables were evaluated Ward's hierarchical clustering analyses, univariate, and multivariate logistic regression analyses. RESULTS A hundred forty-nine of 1107 jSLE patients had NP involvement (13.5%). The most common NPSLE findings were headache (50.3%), seizure (38.3%), and acute confusional state (33.6%). Five clusters were identified with all clinical and laboratory findings. The first two clusters involved neuropathies, demyelinating diseases, aseptic meningitis, and movement disorder. Cluster 3 involved headache, activity markers and other SLE involvements. Idiopathic intracranial hypertension, cerebrovascular disease, cognitive dysfunction, psychiatric disorders and SLE antibodies were in the fourth, and acute confusional state was in the fifth cluster. In multivariate analysis, APA positivity; OR: 2.820, (%95CI: 1.002-7.939), P: 0,050, plasmapheresis; OR: 13.804 (%95CI: 2.785-68.432), P: 0,001, SLEDAI scores; OR: 1.115 (%95CI: (1.049-1.186), P: 0,001 were associated with increased risk for neurologic sequelae. CONCLUSION We detected the prevalence of juvenile NPSLE manifestations in Turkey. We have identified five clusters that may shed light pathogenesis, treatment and prognosis of NP involvements. We also determined risk factors of neurological sequelae. Our study showed that new definitions NP involvements and sequelae for childhood period are needed.

Abstract
OBJECTIVE To evaluate the safety of canakinumab using real-world data in patients with systemic juvenile idiopathic arthritis (sJIA) and autoinflammatory diseases (AID). RESEARCH DESIGN AND METHODS This was a cross-sectional observational, multicenter study. Patients diagnosed with AID and sJIA treated with canakinumab were included in the study. The participating 13 centers retrospectively collected their patients' data. RESULTS A total of 335 patients were involved in the study. Among these patients, 280 were in the AID group and 55 were in the sJIA group. Canakinumab was administered at a median dose of 3 (2.5-4) mg/kg. The median total exposure time to canakinumab was 1.9 (0.8-3.2) years, corresponding to 759.5 patient-years. Seven hundred and seventy-nine total adverse events (AE) were identified. The total incidence of AE, and serious adverse events (SAE) throughout the study period was 1.02 per patient-years. The upper respiratory tract infection rate was 0.7 per patient-years, while the other infection rate was 0.13 per patient-years. While no death was observed in any patient, SAE were observed in 8 patients. Interstitial lung disease, anaphylaxis, or anaphylactoid reactions were not observed in any patient. CONCLUSIONS Real-life data from a large cohort of patients suggests that canakinumab is as safe as claimed in clinical trials.

Abstract
OBJECTIVES To investigate patients who flared after discontinuation of biological disease-modifying anti-rheumatic agents (bDMARDs) and identify risk factors associated with flare. METHODS A multicenter study evaluating systemic and non-systemic juvenile idiopathic arthritis (sJIA and non-sJIA) patients whose bDMARDs were ceased after remission. RESULTS A total of 101 patients whose bDMARDs were ceased after remission was evaluated. Children with sJIA had the lowest risk of flare and 11.1% of 36 sJIA patients experienced flare after a median of 9 (4-24) months of bDMARDs cessation with three of them flaring in the first year. High leukocyte counts in sJIA patients were associated with inactive disease at 1-year after the start of treatment (p = 0.004). In the non-sJIA group, 46.1% patients experienced flare after a median of 7 (1-32) months of biologic cessation, and of these, 25 flared in the first year. Antinuclear antibody positivity (p = 0.02), earlier disease onset (p = 0.03), long disease duration (p = 0.01), and follow-up (p = 0.02) and extended time from diagnosis to first biological onset (p = 0.03) were more common among patients with flare. CONCLUSIONS When considering discontinuation of bDMARDs, it should be kept in mind that the risk of exacerbation requiring re-initiation therapy is quite significant within the first year after discontinuation of therapy.

Abstract
Background Systemic autoinflammatory diseases (SAIDs) are a group of hereditary diseases characterized by inflammatory attacks accompanied by clinical findings such as fever, skin rash, abdominal pain, and musculoskeletal symptoms and with high acute phase response. Objectives This study sought to define the characteristics, to report 24-month follow-up of children with SAIDs and to compare the performances of both the previously validated classification criteria Federici and new Eurofever/PRINTO classification criteria in a multicentre cohort under real-life conditions. Method The medical charts of 60 children diagnosed with SAIDs (CAPS, TRAPS and HIDS) who were followed up regularly every 1–3 months between 2010 and 2021 in 6 pediatric rheumatology centers in Turkey were retrospectively analyzed. Demographic data, clinical findings, laboratory results and treatments were recorded. All patients were analyzed by NGS panel containing 16 genes. Results A total of 60 patients with SAID were evaluated. Among them 30 (50%) were male and 30 (50%) were female. The median age at disease onset and diagnosis were 22 (0–193) months and 72 (2–213) months, respectively. The current age was median 10.3 (1.7–20.4) years. All patients were follow-up with a median 31 (6–97) months. Among 60 patients, 22 were diagnosed with CAPS, 8 with TRAPS and 30 with HIDS. The frequency of clinical symptoms was 95%, arthralgia 63.3%, gastrointestinal complaints 58.3%, urticarial rash 56.7%, myalgia 48.3%, lymphadenopathy 33.3%, respectively. Urticarial rash (86.4%), cold induced rash (45.5%) and arthritis (50%) were significantly higher in CAPS patients compared with other two groups (p< 0.05). Lymphadenopathy (46.7%) was more common in HIDS patients (p = 0.03). When we applied the diagnostic/classification criteria to our cohort, 71.7% met the Federici criteria, 53.3% fulfilled the Eurofever/PRINTO classification criteria. When performance of two diagnostic criteria (Federici and Eurofever/PRINTO criteria) was compared, the proportion of patients fulfilling the Eurofever/PRINTO criteria higher in TRAPS patients compared with other groups (p = 0.008). Statistically significant decreases were found in AIDAI scores, CRP, ESR levels from the 1st month and in the leucocyte counts from the 6th month of the treatment in CAPS patients (p = <0.001, p = 0.035, p = 0.03 and p = 0.006, respectively). In addition, AIDAI scores were correlated with CRP values (p = 0.047). In HIDS patients, there was a statistically significant decrease in AIDAI scores and ESR levels from the 1st month, CRP levels from the 3rd month, and leucocyte counts from the 12th month of treatment (p = <0.001, p = 0.003, p = <0.001 and p = 0.034, respectively). In addition, ESR values were correlated with CRP (p = 0.006). In TRAPS patients, on the other hand, there was a statistically significant decrease in AIDAI scores from the 1st month of treatment (p = 0.018). At the last visit, 93.3% of the patients were receiving anti-IL-1, 5% anti-IL-6, and 1.7% were receiving colchicine. Ninety percent of the patients were in complete remission. Conclusion We showed that the diagnostic/classification criteria may not always be sufficient to make the diagnosis, and there is still low agreement between clinical diagnoses and molecular analyzes. Anti-IL-1 treatments have been found to be quite effective in the treatment from the early period.

Abstract
Objective: To evaluate the effects of photobiomodulation therapy (PBMT) at distinct energy levels on peri-implant bone healing in extra-short implants in a experimental rabbit model. Background: The effect of PBMT on peri-implant bone healing in short implants remains unclear. This explored the effect of PBMT on extra-short implants in terms of bone-implant contact (BIC) length and rate, and implant stability quotient (ISQ). Methods: Fifteen white New Zealand rabbits were randomly divided into five groups. In all groups, extra-short implants (3.5 × 4 mm; Nucleoss T6, İzmir/Turkey) were placed in both tibias of the rabbits. PBMT was performed in four groups (group 1, 5 J/cm2; group 2, 10 J/cm2; group 3, 20 J/cm2; and group 4, 25 J/cm2); no PBMT was performed in the control group. On the 30th day, the rabbits were sacrificed and peri-implant tissue samples were obtained to determine the BIC length and BIC rate. Implant stability levels were measured by resonance frequency analysis using the Osstell penguin device and were determined as ISQ values on the 1st and 30th days of the study. Results: PBMT significantly increased the BIC length and BIC rate in groups 3 and 4 (p < 0.001). For the ISQ values, there were significant differences between the 1st and 30th day (p < 0.001). On the 30th day, the ISQ values were significantly higher in groups 3 and 4 compared with the remaining groups (p < 0.001). Conclusions: In this study, PBMT improved peri-implant bone healing through increase in BIC length, BIC rate, and ISQ parameter values in extra-short implants.

Abstract
OBJECTIVES Behçet's Disease (BD) is a systemic vasculitis affecting many organ systems with the involvement of all sized arteries and veins. Patients with BD may present with varying features. The study aims to determine the main characteristics of pediatric BD patients and also analyze the clustering phenotypes in a large multicentric cohort. METHODS Demographic data, clinical manifestations, laboratory features, treatment schedules, and disease outcomes were achieved from patients' charts retrospectively. A cluster analysis was performed according to phenotype. RESULTS A total of 225 (109 male/ 116 female) patients with BD were enrolled in the study. The median age of disease onset and diagnosis was 131 (36-151) and 156 (36-192) months, respectively. The median time between the onset of symptoms and diagnosis was 23.5 (0-45) months. According to cluster analysis; 132 (58.6%) patients belonged to the mucocutaneous-only cluster (C1) while 35 (15.6%) patients fitted to articular type (C2), 25 (11.1%) %) were in ocular cluster (C3), 26 (11.6%) were in vascular cluster (C4) and 7 (3.1%) belonged to the gastrointestinal cluster (C5). Ocular and vascular clusters were more common in boys (p<0.001), while girls usually presented with the mucocutaneous-only cluster. The clusters had comparable ages upon diagnosis. The disease activity at the diagnosis and the last control was higher in ocular, vascular, and gastrointestinal clusters. CONCLUSIONS We identified five different subtypes in juvenile BD patients. These subtypes express different phenotypes with different outcomes. Our analysis may help clinicians to identify the disease subtypes accurately and to arrange personalized treatment.

Abstract
OBJECTIVES : In the evaluation of children with Kawasaki disease (KD), the age of onset is important and complications may occur if the distinctive features are not assessed accordingly. The objective of the study is to define the clinical and laboratory presentations and treatment outcomes of KD in infants ≤6 months of age compared to those >6 months multicentrically. METHODS : This retrospective study reviewed the medical records of the patients diagnosed with KD and followed up between January 2009 and January 2019. RESULTS : A total of 204 KD patients were enrolled and grouped according to age as Group I (≤6 months, n=31) and Group II (>6 months, n=173). Except for cervical adenopathy (19.3% vs. 47.4%, p=0.03), the major clinical manifestations of KD were similar between groups I and II. However, the frequency of incomplete and atypical KD was higher in Group I (38.7% vs. 24.8%, p=0.04, 38.7% vs. 8.1% p<0.001, respectively). Clinical features such as vomiting/diarrhea (19.3% vs. 1.1% p<0.001), aseptic meningitis (19.3% vs. 2.3%, p=0.001) were more common in Group I. Percentage of neutrophils (45.5 vs. 36, p=0.004) and hemoglobin levels (8 vs. 10.5 gr/dL, p=0.02) were statistically lower and platelet count (737000 vs 400000/mm3, p=0.004) was statistically higher in group I. Coronary artery lesions (CALs) were more common in Group I (48% vs. 20 %, p<0.001). Harada and Kobayashi scores appear to be effective in predicting coronary artery lesions (CALs) and IVIG resistance in the entire cohort. There was no diagnostic delay in group I (5.5 vs 6.5 days, p=0.88). CONCLUSIONS : Since clinical presentations and laboratory features of KD may vary with age, and the frequency of atypical and incomplete presentations is high, awareness of KD in young children should be raised among pediatricians.

Abstract
Objectives Fractal analysis is a mathematical method used for the calculation of bone trabeculation and lacunarity. This study aims to evaluate the relationship between resonance frequency analysis (RFA) and fractal dimension (FD) of peri-implant bone to determine the preload stability of implants. Materials and methods In this study, the results of the fractal analysis calculated from the resonance frequency analysis results taken in the 3rd month of the patients who underwent 2-stage implant by the same doctor and the radiographs taken in the same session were evaluated. A hundred implants in 20 patients were applied in this study. The implant stability quotient (ISQ) values of the implants and fractal dimension values of the peri-implant bone were calculated. Results The findings showed that the ISQ1 (p = 0.008), ISQ2 (p = 0.038), ROI2 (p = 0.013), and ROI3 (p < 0.001) values were statistically significantly higher in men than women. The ISQ1 (p = 0.003), ISQ2 (p = 0.013), ROI1 (p = 0.011), and ROI3 (p < 0.001) of the mandible were statistically higher than the maxilla. The fractal dimension cut-off value to assess prosthetic loading was found 1.198. Conclusion Fractal analysis is a non-invasive method that can be used in conjunction with clinical examination in the prosthetic loading decision of implants. It is a valuable parameter that can be used without the need for an extra device when it is necessary to reduce the clinical study time. Clinical relevance Calculating the fractal dimension of the peri-implant bone is a practical, economical, and applicable method for clinicians. FD calculated from panoramic radiographs used for diagnosis in routine treatments in clinics where access to the necessary devices for ISQ measurement is not available will contribute to clinical practice.

Abstract
Background: The aim of this study was to evaluate the outcomes of patients with the multisystem inflammatory syndrome in children (MIS-C) according to phenotypes of disease and define the prognostic factors for the severe course. Methods: This cross-sectional study included 293 patients with MIS-C from seven pediatric rheumatology centers. A two-step cluster analysis was performed to define the spectrum of disease and their outcomes were compared between each group. Results: Four subgroups were identified as follows: cluster I, predominantly Kawasaki-like features (n = 100); cluster II, predominantly MAS-like features (n = 34); cluster III, predominantly LV dysfunction (n = 47); cluster IV, other presentations (n = 112). The duration of fever was longer in cluster II and the length of hospitalization was longer in both clusters II and III. Laboratory findings revealed lower lymphocyte and platelet counts and higher acute phase reactants (APRs) in cluster II, while patients in cluster IV showed less inflammation with lower APRs. The resolution of abnormal laboratory findings was longer in clusters II and III, while it was shortest in cluster IV. Seven patients died. Among them, four belonged to cluster II, while three were labeled as cluster III. Patients with severe course had higher levels of neutrophil–lymphocyte ratio, mean platelet volume, procalcitonin, ferritin, interleukin-6, fibrinogen, D-Dimer, BNP, and troponin-I, and lower levels of lymphocyte and platelet counts. Conclusion: As shown, MIS-C is not a single disease presenting with various clinical features and outcomes. Understanding the disease spectrum will provide individualized management.

Abstract
OBJECTIVE The study aimed to report the efficacy and safety of anakinra treatment in patients with the refractory multisystemic inflammatory syndrome in children (MIS-C). METHODS This is a cross-sectional retrospective study consisting of pediatric patients diagnosed with MIS-C who were treated with anakinra. RESULTS Among the 378 patients diagnosed with MIS-C, 82 patients (21.6%) who were treated with anakinra were included in the study. The median age of patients was 115 (6-214) months. The median duration of hospitalization was 15 (6-42) days. Sixty patients (73.1%) were admitted to the pediatric intensive care unit. Patients were treated with a median dose of 2.7 mg/kg/day anakinra concomitant with IVIG and steroids. Intravenous anakinra was applied to 12 patients while 70 patients received it subcutaneously. Twenty-eight patients required high dose (4-10 mg/kg/day) anakinra. The median day of anakinra initiation was 2 (1-14) days and the median duration of anakinra use was 7 (1-41) days. No injection site reactions were observed while elevated transaminase levels were detected in 13 patients. Seventy-three patients (89.1%) were discharged without any sequela or morbidity. Seven patients (1.8%) died. Abnormal echocardiographic findings continued in two patients (2.4%) (coronary artery dilatation in one, low ejection fraction in one) at discharge and became normal on the 2nd month. CONCLUSION Based on the results of the study, anakinra was associated with clinical improvements and was safe for most patients with refractory MIS-C.

Abstract
OBJECTIVES To review the real-life data, to provide an input to the literature concerning treatment of juvenile idiopathic arthritis (JIA) with adalimumab (ADL) biosimilar. METHOD This multi-centric retrospective study was conducted among children with JIA, followed up for at least 24-weeks from the initiation of ADL biosimilar (ABP 501) treatment. Adverse events and alterations in disease activity scores were figured out. RESULTS The median age of the group was 15.5 (5-18) years. JIA categories were oligoarticular (n =12), enthesitis-related (ERA) (n=24), psoriatic (PsA) (n=6), and polyarticular (n=4). Uveitis was detected at the initiation of the disease (n=3), during the disease course (n=5), or before the diagnosis (n=1). The first-line treatment preferences were ADL biosimilar (n=37) and etanercept (n=9). On the 6th month of ABP 501, 40 (86.9%) patients had achieved complete remission. Six patients (1 PsA, 1 polyarticular JIA, and 4 ERA) had ongoing active arthritis. Furthermore, all except one of the patients had remission of ophthalmologic findings. No life-threatening adverse events were observed. CONCLUSIONS ABP 501 has a gradual increase in prescription in pediatric rheumatology. Real-life data of the cohort announce that ADL biosimilar is a suitable and effective treatment option for patients with JIA in case of indication.

Abstract
BACKGROUND SARS-CoV-2 related multisystem inflammatory syndrome in children (MIS-C) is a newly defined clinical entity in pediatric ages resembles Kawasaki Disease or toxic shock syndrome. Here we aimed to raise awareness about this SARS-CoV-2 related syndrome. METHODS Children diagnosed with MIS-C and followed in Pediatric Clinic between November 2020 and January 2021, were included in study. Data about patients' demographic characteristics, clinical and laboratory findings, treatment and outcomes were collected from medical records. RESULTS The median age of 20 children with MIS-C was 80.5 months, 11 of them were male. The most common symptoms at admission were fever (100%), abdominal pain (70%), myalgia (50%), and rash (50%). Lymphopenia, elevated inflammatory markers and cardiac enzymes were their main laboratory findings. Cardiac involvement (90%) consisted of myopericarditis, valvulitis, left ventricular dysfunction, and coronary arteritis. Symptoms mimicking acute appendicitis and ileus were due to gastrointestinal involvement (50%). Macular rash on the trunk, erythema on upper eyelids were striking. Empiric antibiotics and intravenous immunoglobulin were used in all patients, glucocorticoids (90%), anti-thrombotic (65%) and vasoactive (45%) agents were used according to severity of disease. Response to IVIG treatment was poor, whereas glucocorticoids have dramatic affect. Seven patients (35%) were monitored in intensive care unit, none of them required intubation, mechanic ventilation or ECMO. The median recovery time, that is, the period when fever subside and inflammatory markers returned to normal was 9.5 days. CONCLUSIONS Glucocorticoids has critical role in treatment of MIS-C, early recognition and treatment may decrease need for intensive care by providing rapid recovery.

The effect of wide-awake anesthesia, intravenous regional anesthesia, and infraclavicular brachial plexus block on cost and clinical scores of patients undergoing hand surgery. HAND SURGERY & REHABILITATION 2021; 40:382-388. [PMID: 33823293 DOI: 10.1016/j.hansur.2021.03.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/21/2021] [Accepted: 03/30/2021] [Indexed: 11/19/2022]
Abstract
The aim of our study was to compare the clinical results and costs of wide-awake local anesthesia no tourniquet (WALANT), intravenous regional anesthesia (IVRA), and infraclavicular brachial plexus block (IC-BPB). The patients were divided into WALANT, IVRA, IC-BPB groups, each with 50 patients. Demographic information, induction time, use of sedation, number of patients who were converted to general anesthesia, time in postanesthesia care unit (PACU), amount of bleeding during surgery, presence of tourniquet pain, hand motor function during surgery, time to onset of postanesthesia pain, discharge time, complications, and anesthesia costs were compared. Sedation was given to 12 IC-BPB patients, 9 IVRA patients and 5 WALANT patients. Of these patients, 6 undergoing IC-BPB, 5 undergoing IVRA and 4 undergoing WALANT were converted to general anesthesia (p = 0.80). PACU time and anesthesia costs were the least in the WALANT group, followed by the IVRA group (p < 0.001, p < 0.001). Intraoperative active voluntary movements were best preserved in the WALANT group; however, bleeding was highest in the WALANT group (p < 0.001, p < 0.001). Tourniquet pain was the higher in the IVRA groups, while postoperative pain in the surgical area developed the fastest in this same group (p = 0.029, p < 0.001). Time to discharge was similar in WALANT and IVRA groups, and the longest in the IC-BPB (p < 0.001) group. There was no difference among the groups in terms of patient satisfaction (p = 0.085, p = 0.242 for the first and second survey question). In the current study, WALANT appears to be a suitable alternative to IVRA and IC-BPB methods, with better preservation of active intraoperative movement, lower cost, and shorter time spent in PACU at the expense of higher bleeding.

Real-Life Data From the Largest Pediatric Familial Mediterranean Fever Cohort. Front Pediatr 2021; 9:805919. [PMID: 35127599 PMCID: PMC8812847 DOI: 10.3389/fped.2021.805919] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Accepted: 12/27/2021] [Indexed: 11/29/2022] Open
Abstract
Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease manifesting phenotypic heterogeneity. It is a clinically diagnosed disease supported by MEditerranean FeVer (MEFV) gene mutation analysis. However, the phenotype-genotype correlation is not yet established clearly. We aimed to determine the clinical findings, phenotype-genotype correlation, and treatment outcomes within a large pediatric FMF cohort. The medical charts of children with FMF who were diagnosed and followed up at the eight pediatric rheumatology units were reviewed retrospectively. All patients in the cohort were analyzed for sequence variants in exon 2,3,5 and 10 of the MEFV gene. Patients without any mutations or with polymorphisms including R202Q were excluded. A total of 3,454 children were involved in the study. The mean ± standard deviation of current age, age at symptom onset, and age at diagnosis were 12.1 ± 5.2, 5.1 ± 3.8, and 7.3 ± 4.0 years, respectively. Of 3,454 patients, 88.2% had abdominal pain, 86.7% had fever, 27.7% had arthritis, 20.2% had chest pain, 23% had myalgia, and 13.1% had erysipelas-like erythema. The most common MEFV mutation patterns were homozygous (32.5%) and heterozygous (29.9%) mutations of exon 10. Homozygous M694V was present in 969 patients (28.1%). Allele frequencies of common mutations were M694V (55.3%), M680I (11.3%), V726A (7.6%), and E148Q (7.2%). Children carrying homozygous or compound heterozygous exon 10 mutations had an earlier age of disease onset (4.6 vs. 5.6 years, p = 0.000) and a higher number of attacks per year (11.1 vs. 9.6, p = 0.001). Although 8% of the patients had a family history of amyloidosis, 0.3% (n = 11) had the presence of amyloidosis. M694V homozygosity was detected in nine patients who developed amyloidosis. Colchicine resistance was present in 4.2% of our patients. In this largest pediatric cohort reviewed and presented to date, patients with exon 10 mutations, particularly the M694V homozygous mutation, have been demonstrated earlier disease onset, annual attack count, and more frequent colchicine-resistant cases. Although E148Q is considered as a polymorphism in some populations, it was identified as a disease-causing mutation in our cohort. Secondary amyloidosis is still happening in adults however, it is extremely rare among children, presumably due to increased awareness, tight control, and the availability of anti-IL1 agents in colchicine-resistant cases.

Abstract
BACKGROUND/AIMS Helicobacter pylori is classified as a gram-negative bacteria and can cause significant diseases, including gastric cancer, mucosa-associated lymphoid tumor, peptic ulcer, and chronic gastritis. Recent studies have shown that some autoimmune diseases are also associated with H. pylori. In the past decades, polymorphisms of certain genes of H. pylori, mechanisms and strains of H. pylori, and new therapeutic approaches have continued to be defined. Bioinformatic tools continue to be used in drug design and vaccine design. This study aimed to investigate the cag pathogenicity island (cagPAI) of H. pylori using an in silico approach, which could contribute to vaccine studies. MATERIALS AND METHODS The pathogenicity island of H. pylori was obtained from GenBank and analyzed with ClustalW software. Structures of cag Virb11 (Hp0525) and an inhibitory protein (Hp1451) were obtained, and codon optimization and secondary and tertiary structure prediction for the cagPAI of H. pylori were analyzed using Garnier-Osguthorpe-Rabson IV secondary structure prediction method and self-optimized prediction method with alignment software. The BcePred prediction server was used to distinguish linear B-cell epitopes, and prediction of T-cell was obtained with NetCTL and MHCPred. RESULTS According to the physicochemical parameters, the cagPAI of H. pylori was analyzed and found to be stable, and 2 B-cell epitopes of cagPAI of H. pylori and 2 T-cell epitopes of cagPAI were found in this study. CONCLUSION B- and T-cell epitopes that we have identified can induce both humoral and cellular immune responses. Thus, these epitopes have a potential for vaccine studies. Consequently, this in silico analysis should be combined with other pieces of evidence, including experimental data, to assign function.

Protracted febrile myalgia syndrome as the first manifestation of familial Mediterranean fever in children: case-based review. Rheumatol Int 2020; 41:213-218. [PMID: 32895731 DOI: 10.1007/s00296-020-04696-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Accepted: 08/27/2020] [Indexed: 11/24/2022]
Abstract
Protracted febrile myalgia syndrome (PFMS) is one of the rare conditions characterized by long standing severe myalgia and fever in familial Mediterranean fever (FMF) patients. Laboratory studies show elevated values of inflammatory markers and normal creatinine phosphokinase (CPK) levels. Rarely, PFMS may be the first manifestation of FMF and this makes the diagnosis of FMF and PFMS challenging. The aim of this report was to describe case series of PFMS patients without previous diagnosis of FMF and discuss with other pediatric PFMS cases described in the literature. Six patients with PFMS as the first manifestation of FMF from two Pediatric Rheumatology clinics were presented. The male: female ratio was 1:1. The median (min-max) age at diagnosis was 7.05 (5.5-15.5) years. All patients had severe myalgia. No fever was detected in two patients. Only one patient had rash. Markedly elevated acute phase reactants were observed in all patients. CPK levels were normal in all patients. Also, we searched the PubMed/MEDLINE, Google Scholar, Web of Science and Scopus databases from inception to May 2020, using the keywords 'familial Mediterranean fever, protracted febrile myalgia, child' and 52 pediatric PFMS were found. In the literature, three patients did not have fever, and nineteen patients were not previously diagnosed with FMF as our patients. As a conclusion, PFMS may be the first manifestation of FMF. It should be suspected in cases with prolonged severe myalgia with or without fever, and high acute phase reactants.

Abstract
Since the Syrian civil war in 2011, an estimated number of 3.6 million Syrian refugees crossed into Turkey, and almost half of them were children. The distribution of rheumatic diseases in Syrian refugee children is not known. The aim of this study was to describe the profile of rheumatic diseases in Syrian refugee children living in Turkey. The demographic data, clinical and laboratory findings, medications, complications and outcome results of Syrian refugee children who had visited Pediatric Rheumatology Departments of University of Health Science Kanuni Sultan Süleyman Research and Training Hospital, Ümraniye Research and Training Hospital, Şanlıurfa Research and Training Hospital, and Cengiz Gökçek Maternity and Gynecology Hospital between April 1, 2011, and September 1, 2019, were evaluated retrospectively. A total of 151 patients were included in the study. Among them, 51 patients had juvenile idiopathic arthritis (JIA), 49 had familial Mediterranean fever (FMF), 43 had vasculitis, and 8 had connective tissue diseases. Homozygous M694V mutation was the most common mutation among FMF patients. Oligoarticular JIA (41.2%) was the most frequent type of JIA, and enthesitis-related arthritis (ERA) (27.5%) was the second one. The frequency of systemic JIA was 11.8%. One patient with SLE died due to complicated meningitis. This is the first study evaluating the distribution of rheumatic diseases in Syrian refugee children. Clinical follow-up of rheumatologic diseases is difficult in Syrian refugees due to language barriers, social and cultural differences. Health care systems should be well organized to provide appropriate care to asylum seekers.

Abstract
OBJECTIVE There is still ongoing research on the relationship of arcuate eminence (AE) and superior semicircular canal (SSC). We aimed to evaluate the precision of predictability of SSC through the morphology of AE via radiological means. MATERIALS AND METHODS This investigation is performed on 12 dry skulls belonging to Mersin University Medical Faculty department of anatomy. Computed tomography (CT) assessment is performed with 0.5-mm-thin sections temporal bone algorithm on dry skulls which were marked with fixated copper wire by scotch tapes on the most prominent part of the middle fossa floor assuming the location of AE. The data are reformatted on the workstation with vitrea 2.0. The distances of the determined three points including lateral (A), apical (B), and medial (C) of the SSC and the copper wire are measured radiologically. Also, the height between the most apical part of the SSC to the floor of the skullbase (H) is measured. The angles between the placed copper wires and the SSC (E) are calculated. The angle between SSC and the midpoint of the IAC (F) and SSC to the sulcus of the greater GSPN (G) were measured. The nearest distance was measured between the most posterior part of the SSC and the point marked by the perpendicular line drawn from the medial border of the petrous bone to the most posterior part of the internal auditory canal (IAC) (D). RESULTS The right and left A, B, and C distances are 2.54+/- 2.75, 3.67+/-3.16, 5.85+/-3.77; 2.92+/-2.24, 3.68+/-2.93, 6.09+/-3.40, respectively. We could not find any statistical significance when the right A, B, and C distances were compared with the left values. Examination of the values revealed that C distance is greater than the A distance of the same side both for right (p=0.040) and left (p=0.022) measurements. The calculated left and right E angles are 30.313+/-12.838, and 35.558+/-18.437 degrees, respectively. Statistical significance was not found between the right and left angles. The right and left F, G angles were 53.17, 47.25; 93.58, 100.92 degrees; and D distances are 8.01, 8.13 millimeters, respectively. Statistical significance was not found when right and left E, F, G angles and D distances were compared. Among 12 left and 12 right sides, the copper wire was found to be nearly overlapping to SSC in two in the right and only one in the left. CONCLUSION This study reveals that there is a great variability predicting the exact location of SSC through the prominence of AE. Complementary studies are needed with greater number of dry skulls and cadavers. Comparison of different hypothesis including the effect of temporal lobe sulcus is to be discussed to better enlighten the exact relationship of the aforementioned anatomical structures.

Abstract
BACKGROUND Food allergy, which becomes an important public health problem, can lead to important morbidity and mortality. Patients with food allergies are more likely to first present to their primary care physicians. We aimed to determine the knowledge of primary care physicians with regard to management of food allergies and anaphylaxis. METHODS Primary care physicians were surveyed via a questionnaire aimed to document their knowledge and attitudes about food allergy and anaphylaxis management. RESULTS A total of 297 participants completed questionnaires, 55.6% of which were female. Participating physicians had a mean of 17.0 ± 6.1 years of experience. Participants answered 47.2% of knowledge-based items correctly. Overall, participants fared poorly with regard to their knowledge on the treatment of food allergies and anaphylaxis. For example while 60.7% knew that a child can die from the milk allergy reaction, only 37.5% were aware that a child with IgE mediated milk allergies cannot eat yoghourts/cheese with milk. Besides, 53.1% of them chose epinephrine as their first treatment of choice in case of anaphylaxis, yet only 16.6% gave the correct answer about its dosage. Nearly a third of participants (36.7%) felt they were knowledgeable enough regarding the management of patients with food allergies, while 98.2% extended their request for future periodic educational meetings on allergic disorders. CONCLUSION Knowledge of food allergy and anaphylaxis among primary care physicians was unsatisfactory. Provision or periodic educational programmes should be aimed at improving the standard of practice as acknowledged by the participants.

Abstract
A simple, fast, inexpensive sensitive/selective nucleic acid sensor based on the quartz crystal microbalance system (QCM) was developed for the detection of telomerase. A specially designed oligonucleotide probe, that is complementary to the template region of the telomerase enzyme, was immobilized onto the silver electrodes of piezoelectric crystals with polyethyleneimine adhesion cross-linked with glutaraldehyde. Optimum coating and immobilization conditions were determined. The QCM nucleic acid sensor was used for the detection of telomerase enzyme in human cervix carcinoma cell (HeLa) lysates. A significant difference between the telomerase negative cells (BHK) from HeLa cells, which was used for qualitative and quantitative detection of telomerase. An almost a linear correlation with the protein concentration was obtained with a R 2 value of 0.9621. The linear correlation coefficients (R2) for HeLa and BHK cell lysate obtained by applying Langmuir adsorption model, were 0.9630 and 0.9766, respectively. Telomerase activity was confirmed by stretch-PCR and fluorometric (F)-TRAP within HeLa extracts. The results obtained both with the QCM system developed in this study and F-TRAP method applied is significantly correlated (r = 0.968, p<0.001).
