Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease of childhood and adulthood. Development of systemic amyloidosis and frequent attack influence quality of life and survival. There is sporadic evidence indicating subclinical inflammation in patients with FMF. We aimed to assess subclinical inflammation using neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and C-reactive protein (CRP) in pediatric patients with FMF in the attack-free period. In this retrospective study, we reviewed the files of all FMF patients in our pediatric rheumatology outpatient clinic in a tertiary center and enrolled those with sufficient clinical and laboratory data. We also enrolled 73 controls. We grouped the patients according to being in attack period or attack-free period. We compared CRP, NLR, PLR, and WBC (white blood cell) levels between different mutations and polymorphisms. We also compared patients in the attack period with those in attack-free period. We enrolled 61 patients in attack period, 509 patients in attack-free period, and 73 controls. There was no difference between patients with different mutations with respect to NLR or PLR levels in the attack-free period. However, CRP levels were higher in patients with homozygous exon 10 mutations, especially those with homozygous M694V mutations compared with other mutations. However, CRP levels were mostly normal in these patients. Our data are against the reported fact that patients with FMF have higher NLR or PLR levels in attack-free periods. However, CRP levels were higher in the presence of homozygous exon 10 mutations (in particular homozygous M694V mutations).

BackgroundWe aimed to determine the incidence of multisystem inflammatory syndrome in children (MIS-C) in pediatric coronavirus disease 2019 (COVID-19) cases and to define the relationships between the need for hospitalization, the development of MIS-C, and the Charlson Comorbidity Index (CCI) and Pediatric Comorbidity Index (PCI) scores.MethodsAll pediatric COVID-19 cases between March 25, 2020, and December 28, 2020, in the Marmara University Pendik Training and Research Hospital were enrolled. Patients who needed hospitalization were determined. Hospital records were re-examined to identify those diagnosed as having MIS-C. The CCI and PCI were used to validate the comorbidity status.ResultsAmong 2,055 pediatric COVID-19 cases, 1,340 were included in the study, and 213 patients (15.9%) had at least one comorbidity. All the patients or their parents were interviewed about the need for hospitalization, except for the acute period. Six patients had MIS-C, which corresponds to a MIS-C incidence of 0.4%. The need for hospitalization increased in the patients with comorbidities (P < 0.05). No correlation was found between the comorbidity scores and the development of MIS-C. The need for hospitalization increased in the patients with CCI scores of ≥2 and PCI scores of ≥4 (P < 0.05).ConclusionsOur study is the first to examine the incidence of MIS-C, which was 0.4%, by long-term follow up of pediatric COVID-19 cases and to demonstrate that the CCI and PCI can be used to predict the need for hospitalization and prognosis of pediatric patients with COVID-19.

The term anti-nuclear antibody (ANA) is used to define a large group of autoantibodies which specifically bind to nuclear elements. Although healthy individuals may also have ANA positivity, the measurement of ANA is generally used in the diagnosis of autoimmune disorders. However, various studies have shown that ANA testing may be overused, especially in pediatrics clinics. Our aim was to investigate the reasons for antinuclear antibody (ANA) testing in the general pediatrics and pediatric rheumatology clinics of our hospital and to determine whether ANA testing was ordered appropriately by evaluating chief complaints and the ultimate diagnoses of these cases. The medical records of pediatric patients in whom ANA testing was performed between January 2014 and June 2016 were retrospectively evaluated. Subjects were grouped according to the indication for ANA testing and ANA titers. ANA tests were ordered in a total of 409 patients during the study period, with 113 positive ANA results. The ANA test was ordered mostly due to joint pain (50% of the study population). There was an increased likelihood of autoimmune rheumatic diseases (ARDs) with higher ANA titer. The positive predictive value of an ANA test was 16% for any connective tissue disease and 13% for lupus in the pediatric setting. in the current study, more than one-fourth of the subjects were found to have ANA positivity, while only 15% were ultimately diagnosed with ARDs. Our findings underline the importance of an increased awareness of correct indications for ANA testing.

: This study aimed to evaluate the ability of ChatGPT-5, a multimodal large language model, to perform automated ASPECTS assessment on non-contrast CT (NCCT) in patients with acute ischemic stroke. : This retrospective, single-center study included 199 patients with anterior circulation AIS who underwent baseline NCCT before reperfusion therapy between November 2020 and February 2025. Each NCCT was evaluated by two human readers and by ChatGPT-5 using four representative images (two ganglionic and two supraganglionic). Interobserver agreement was measured with the intraclass correlation coefficient (ICC), and prognostic performance was analyzed using multivariable logistic regression and receiver operating characteristic (ROC) analysis for 3-month functional independence (mRS ≤ 2). : ChatGPT-5 demonstrated good-to-excellent agreement with expert consensus (ICC = 0.845; 95% CI, 0.792-0.884; κ = 0.79). ChatGPT-ASPECTS were independently associated with 3-month functional independence (OR = 1.28 per point; = 0.004), comparable to consensus-ASPECTS (OR = 1.31; = 0.003). Prognostic discrimination was similar between ChatGPT-5 and consensus scoring (AUC = 0.78 vs. 0.80; = 0.41). : ChatGPT-5 achieved high reliability and strong prognostic validity in automated ASPECTS assessment without task-specific training. These findings highlight the emerging potential of large language models for quantitative image interpretation, though clinical implementation will require multicenter validation and regulatory approval.

IntroductionTumor lymphocyte infiltration demonstrates a positive effect on patient survival in breast cancer, melanoma, renal cell carcinoma, and lung cancer. This study aimed to elucidate the relationship between tumor-infiltrating lymphocyte (TIL) ratio and disease-free survival (DFS) and overall survival (OS) by considering localization, clinical and pathological features, microsatellite instability (MSI) status, mutation status, and demographic data.MethodPatients (n=248) diagnosed with colorectal cancer stages 1, 2, and 3 were analyzed retrospectively. Patients with an Eastern Cooperative Oncology Group performance score of <2 were excluded. Clinical characteristics, age, gender, histopathologic features, TIL ratio, and carcinoembryonic antigen (CEA) level of the patients were recorded.ResultsStage, CEA level, TIL ratio, N stage, T stage, and lymphovascular invasion were statistically significant. Early stage (p=0.019), low CEA level (p≤0.001), high TIL ratio (p=0.046), low N stage (p=0.004), low T stage (p=0.016), and absence of lymphovascular invasion (p=0.037 and p=0.046) were associated with longer DFS. Lymphovascular invasion, N stage, CEA levels, and TIL ratio were analyzed using multivariate analysis. According to the results, the hazard ratio (HR) for the TIL ratio was 1.68 (95% confidence interval (CI): 1.005-2.807; p=0.048), and the HR for the CEA level was 0.49 (95% CI: 0.293-0.846; p=0.01).ConclusionRegarding the outcomes of this research, the TIL ratio was found to be an effective indicator of DFS, confirmed via multivariate analysis to present a 32% reduction in the risk of recurrence/relapse. The TIL ratio was identified as a prognostic factor beyond the effects of stage, grade, lymphovascular invasion, CEA level, and MSI status. The current data provides substantial evidence to support the ratio’s consideration in staging guidelines.

The aim of this study is to ensure that the location selection of the officers of the personnel class in the Land Forces Command is effective and needs to be met to determine the criteria used in the selection of the place of appointment or which is the most important and to reveal the preference order to the officers making the choice. In this survey, a face-to-face interview technique and 10 subquestionnaires of captain majors were applied. In the questionnaire technique, the weights of the criteria were determined by using the Max100 method, then the values of the criteria were determined by the Max100 method, and the alternatives were graded and ranked by using grey relational analysis (GRA) method and PROMETHEE method which are multicriteria decision-making techniques. As a result of this analysis, the assignment locations are listed and the importance ratings of the criteria used in the selection of the assignment location are determined.

Despite the increasing frequency of anaphylaxis, there is inadequate information on the etiology and clinical features in various countries, regions and age groups, especially in developing countries. Our aim is to assess the etiology and clinical findings of anaphylaxis in Turkey. Gathering reliable data about the etiology and clinical findings of anaphylaxis in the general population will decrease the related morbidity and mortality. We obtained the names and phone numbers of individuals who had been prescribed an epinephrine auto-injector with a diagnosis of anaphylaxis from ministry of health. Demographic data, clinical history of the first episode of anaphylaxis including the triggering agent, clinical findings, course of hospitalization, and the management of anaphylaxis were obtained by phone survey. A total of 843 patients with a mean age of 21.4±17.3 years were evaluated. There was a significant male predominance among children younger than 10 years of age but a female predominance in older subjects. The most common causes of anaphylaxis were foods(40.1%) in children and bee venom(60.8%) in adults. The biphasic reaction rate was 4.3% and the median length of stay at an emergency department was 4.0 hours. Almost 60% of the patients had recurrent anaphylaxis episodes. Only 10.7% of the cases were prescribed an epinephrine auto-injector at their first anaphylaxis episode and only 59.2% of the patients were referred to an allergist during discharge from the emergency department. In Turkey, bee venom was the most common cause of anaphylaxis, followed by food and drug. While more than a half of patients reported recurrent attacks; only 10% had been prescribed epinephrine auto-injector kit after their first episode. Strategies to improve the anaphyalxis management are therefore urgently required.

The aim of this study was to evaluate the risk factors of disease severity to facilitate better management of children with severe atopic dermatitis (AD). All the patients were diagnosed using Hanifin-Rajka criteria. After medical and family histories were obtained and a detailed physical examination was performed, disease severity was determined with the objective SCORing Atopic Dermatitis (SCORAD) index. Skin prick tests were performed, and percent of peripheral blood eosinophils, total serum IgE and specific IgE were measured. The median age of the 501 patients was 15 months (interquartile range [IQR]: 6-40 months), and 62.9% (315) were male. Sensitization to at least one allergen and foods was observed in 40.3% (202) and 30.9% (155) of all patients, respectively. Of the study group, 17.6% (88) had severe disease. When logistic regression analyses were performed, with adjustments, the risk factors for severe AD were determined to be eosinophilia (odds ratio [OR] 1.137, 95% confidence interval [CI] 1.062-1.217; p=0.003) and food allergen sensitization (OR: 1.937, 95%CI: 1.217-3.084; p=0.005). The patients with severe AD had sensitization to common allergens, food allergens and eosinophilia more frequently than those with mild-moderate disease (p=0.001, p=0.001 and p=0.005, respectively). Eosinophilia may predict severe disease and allergic sensitization. Further large-scale follow-up studies are needed to improve the reliability and relevance of this relation.

Background: Several studies have demonstrated a relationship between asthma and obesity. However, the results have been conflicting with regard to the relationship between fractional exhaled nitric oxide (FeNO), used as a marker of airway inflammation in asthmatic patients, and obesity. We aimed to evaluate the association of FeNO with obesity and obesity-related metabolic complications in asthmatic and nonasthmatic children. Methods: The study population included children aged between 6 and 17 years and consisted of 4 groups: obese asthmatics (n = 52), normal-weight asthmatics (n = 49), obese nonasthmatics (n = 51) and normal-weight nonasthmatics (n = 42). FeNO measurement and spirometry were performed for all patients. To evaluate the metabolic complications, serum lipids, glucose and insulin levels were measured. Insulin resistance (IR) was estimated by the homeostasis model assessment, HOMA-IR. All participants were evaluated for the presence of metabolic syndrome (MS). Results: The mean age for the 194 subjects participating in the study was 11.6 ± 2.5 years. The FeNO level of asthma patients with MS was not different from those without MS (14.5 ± 8.0 and 16.7 ± 8.7, respectively, p = 0.449). In the nonasthmatic group, subjects with MS had a higher FeNO level than subjects without MS (12.5 ± 5.1 and 17.3 ± 8.3, respectively, p = 0.014). Spearman's rank correlation coefficients revealed a positive correlation between FeNO and body mass index (BMI; p = 0.049, r 2 : 0.204) in the nonasthmatic group and after multivariate regression analysis, BMI still persisted as an independent risk factor for FeNO. Conclusion: We found a positive correlation between BMI and FeNO level which suggests a link between obesity and increased airway inflammation in nonasthmatic children.
