ABSTRACT

BACKGROUND AND AIM: Since there is a limited number of predictive models designed for pediatric patients with pulmonary embolism (PE), healthcare providers have resorted to utilizing the Wells criteria and PE Rule-out Criteria (PERC) that have been validated for use in adults. The objective of the study is to identify the predictive factors for PE and assess the effectiveness of the PERC, Wells, and pediatric-specific PE (PPE) criteria. METHODS: The study included individuals between the ages of 0-18 years who underwent pulmonary CT angiography and/or ventilation-perfusion scintigraphy with suspicion of PE. Demographic characteristics, symptoms, physical examination findings, risk factors, and laboratory and imaging results were retrospectively analyzed, and PERC, Wells, and PPE criteria were applied to the study population. RESULTS: Of the 110 patients included in the study, 27 (24.5%) had PE. Saturation, albumin, cough, calf swelling, central catheter, and malignancy were found to significantly contribute to the model. The total weighted risk score, which represents the sum of all predictive scores, ranged from 0 to 16 with a mean of 5.41 ± 4.02. When the cut-off >6.5, the model had good discrimination power for positive PE (AUC 0.79, 77% sensitivity, and 70% specificity). In our study, the Wells criteria showed a sensitivity of 96% and a specificity of 24%. The PERC exhibited a sensitivity of 96% and a specificity of 21%, while the PPE demonstrated a sensitivity of 74% and a specificity of 30%. CONCLUSION: While the sensitivity of Wells, PERC, and PPE models was higher than our developed model, their specificities were considerably lower than our model.

ABSTRACT

BACKGROUND: There exists insufficient information about the natural course of incidental pulmonary nodules (IPN) determined on tomography in children. The aim was to determine the characteristic features and factors affecting the course of IPN. METHODS: This retrospective study included patients who presented at the Pediatric Pulmonology, Allergy & Immunology Section of Akdeniz University Hospital between January 2014-2020, and were determined with pulmonary nodules on high-resolution computed tomography (HRCT). The patients were separated into two groups as those with a nodule decreased in size or which had disappeared on the follow-up HRCT (Group 1) and those with a nodule which had remained at the same size (Group 2). These two groups were compared in respect to demographic data, nodule size and characteristics, and accompanying findings on HRCT. RESULTS: A total of 177 nodules were determined in the 66 patients included in the study. A follow-up HRCT was taken within mean 16.29±11.38 months in 27 patients. In these patients, 78 nodules were determined on the initial HRCT. On the follow-up, twelve of the nodules were seen to have shrunk or disappeared compared to the initial images, 66 had remained the same size, and none had grown. The mean age of the patients in Group 1 was statistically significantly lower than that of patients in Group 2 (p < 0.001). The rates of an accompanying mosaic attenuation pattern (p < 0.001) on HRCT and subsolid density (p=0.011) of the nodules in Group 1 were statistically significantly higher compared to Group 2 and the rate of calcification content was statistically significantly lower (p=0.002). No suspicious or confirmed malignancy was observed in any case throughout the mean follow-up period of 38.33±16.5 months after the initial HRCT. CONCLUSIONS: The young age of patients, subsolid structure of nodules, calcification content and the presence of an accompanying mosaic attenuation pattern on HRCT, could be useful factors in the estimation of size in the follow-up of nodules.

ABSTRACT

OBJECTIVE: To compare class I/II cystic fibrosis transmembrane conductance regulator (CFTR) mutations to class III-V mutations with regards to cystic fibrosis disease severity markers in children. MATERIAL AND METHODS: This study was designed as a cross-sectional study in Antalya province, located on the south coast of Turkey. The study included 38 cystic fibrosis patients aged between 0.6 and 18 years. The CFTR genotype of the patients was categorized into 2 groups based on the presence or absence of class I or class II mutations in any of the alleles. Group I comprised 8 homozygous, 8 with unknown alleles, and 8 compound heterozygous patients, and group II comprised 11 homozygous and 3 compound heterozygous patients. The groups were analyzed in respect of cystic fibrosis disease severity markers, such as spirometry, ShwachmanKulczycki score, body mass index (BMI), sweat chloride concentration, chronic Pseudomonas aeruginosa infection, annual exacerbation frequency, and severe exacerbations requiring hospitalization during the previous year. RESULTS: In the comparison of group I and group II patients, a significant difference was observed in pancreas insufficiency (83.3% vs. 35.7%; P = .005), chronic P. aeruginosa infection (58.3% vs. 7.1%; P = .002), cough severity score (1.7 ± 1.1 vs. 0.9 ± 1.5; P = .029), number of severe exacerbations requiring hospitalization during the previous year (0.9 ± 1 vs. 0.3 ± 0.8; P = .03), and sweat chloride levels (76.7 ± 15.2 vs. 61 ± 22.3; P = .02). All these values were higher in group I patients. The mean BMI values (15.8 ± 2.2 vs. 17.6 ± 2.8; P = .03) were lower in group I patients. CONCLUSION: There seems to be a difference between class I/II CFTR mutations and class III-V mutations on the severity of the disease in cystic fibrosis patients.

ABSTRACT

Background/ aim: Since January 2015, the Cystic Fibrosis Newborn Screening (CFNS) program has been implemented in Turkey. We aimed to evaluate the demographic, clinical, and laboratory data of cases referred from the CFNS program and to determine the most suitable cut-off value for immunoreactive trypsinogen (IRT)-1 and immunoreactive trypsinogen (IRT-2) that are used in the CFNS program in Turkey. Materials and methods: A total of 156 Turkish Caucasian subjects were determined as positive cases during 3 years, from January 2015 to January 2018, and were referred to the pediatric pulmonology clinics of Akdeniz University Hospital, Antalya, Turkey, for the national CFNS program. The evaluation was made considering the IRT-1 and IRT-2 values, demographic characteristics, sweat test results, CFTR genotypes, and diagnoses. Results: Nine patients were diagnosed with cystic fibrosis (CF). Eight were diagnosed with CF-related metabolic syndromes and three were determined to be CF carriers. The ratio of CF to CF-related metabolic syndrome was determined as 1.1:1. Considering the limits of the present CFNS program and the IRT method, the positive predictive value (PPV) for the referred cases was determined as 5.8%. When a cut-off value of 105.6 ng/mL was taken for IRT-1, sensitivity was 100%, specificity was 59%, and PPV was 12.8%. For a cut-off value of 88.75 ng/mL for IRT-2, sensitivity was determined as 90%, specificity as 65%, and PPV as 15.2%. Conclusion: This is the first detailed clinical study to evaluate the data from the CFNS program along the Mediterranean coast of Turkey. As false positive results are extremely high in Turkey, there is an urgent need for revision of the IRT-1 and IRT-2 limits by evaluating the data of the whole country.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate radiological, clinical, and demographic data of patients with noncystic fibrosis bronchiectasis and to compare high-resolution computed tomography (HRCT) scores based on the demographic and clinical characteristics. MATERIALS AND METHODS: A total of 34 patients (18 male, 16 female) were assessed in terms of age at symptom onset, age at diagnosis, annual attack frequency, cough severity score, physical examination findings, and pulmonary function test results. Modified Bhalla scoring system (B total) and anatomical prevalence degree score (D total) were used for HRCT examination. RESULTS: There was a strong negative correlation between forced expiratory volume at first second (FEV1) and bronchial dilatation degree (SBRDIL). There was a moderate negative correlation of FEV1, forced vital capacity (FVC), and maximum mid-expiratory flow rate (MEF; 25-75) with bronchiectasis degree (EXBRNC), bronchial wall thickness degree (SBWTHICK), and mucus accumulation in the major airways (PMPLA). The B total, D total, EXBRNC, and SBRDIL scores were significantly higher in patients with hemoptysis and sputum. In comparing B and D total scoring systems, B total provided better results in terms of rale, annual exacerbation frequency (AEF), cough severity score (CSS), and FEV1 values. CONCLUSION: As it is proved using HRCT, pulmonary function impairment, sputum production, hemoptysis, and increase in AEF strongly correlating with objective HRCT scoring can be accepted as markers for pathological changes due to bronchiectasis.
