MDCT devices still require further investigation when used in pediatric surgical pathologies. Reconstructed images of VB can reveal images close to the real anatomy. In patients with a suspicion of foreign body ingestion, initial VB may help to determine the presence and exact localization of the foreign body and if negative, may reduce the number of unnecessary rigid bronchoscopies. None of the patients with negative VB had foreign bodies. Positive VB may help to shorten the operative time by providing information about the localization and size of the foreign body.

Rheumatoid arthritis (RA) is a chronic, inflammatory, and autoimmune disease that can cause permanent joint damage. In our study, we aim to analyze the change in calprotectin levels following the low-density exercise levels applied to the patients with RA. Twenty-eight patients with RA and 30 healthy controls were included in this study. To evaluate the activity of disease in RA, scores of disease activity that has increased (DAS-28) are figured. Calprotectin, nitric oxide (NO), white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and rheumatoid factor (RF) levels are tested as the laboratory evaluation. Calprotectin, NO, CRP, ESR, WBC, and RF levels were significantly higher in the patient group compared to the control group (p < 0.01, p < 0.001, p < 0.01, p < 0.01, p < 0.01, and p < 0.05, respectively). In correlation analysis applied to the patient group with RA, there has been determined a positive relation with calprotectin, and DAS-28, CRP, NO, RF, and WBC (p < 0.001, p < 0.05, p < 0.001, p < 0.05, and p < 0.05, respectively). In result of the low-density exercise treatment applied to patients with RA for 8 weeks, there has been determined a significant decrease in calprotectin, DAS-28, NO, CRP, ESR, and RF levels (p < 0.05, p < 0.001, p < 0.01, p < 0.05, p < 0.05, and p < 0.05, respectively). As a result, a significant relation is found between RA disease activity and calprotectin levels and other inflammatory parameters. At the same time, it shows that calprotectin which is a significant indicator of local inflammation can be used as a good identifier in following up exercise treatment.

Controversy still exists concerning the diagnosis and treatment of congenital lobar emphysema (CLE). Although surgical removal of the affected lobe is the most commonly accepted form of treatment, detection of milder or even asymptomatic cases is usually followed by a more conservative management of patients, i. e. non-surgical treatment and follow-up. We therefore decided to evaluate our patients with CLE, placing special emphasis on treatment and diagnostic techniques. We also evaluated quantitative analyses of alveolar diameters. Fourteen children with CLE were analysed retrospectively, including age, sex, clinical picture, localisation, diagnostic and surgical modalities and histopathologic diagnosis. The alveolar diameters of affected lobes were compared with those of the lobectomised patients with other non-obstructive respiratory diseases. All children but one had severe respiratory distress as an initial symptom. All patients, except newborns, had a history of pulmonary infection. All cases underwent thoracic CT examination as the main radiologic method. In all of the patients, only one lobe was affected. We found an obvious mediastinal shift and atelectasis of adjacent lobes due to compression of the affected lobe. The affected lobe was therefore surgically removed in all of the children. In one case, we had to carry out a partial lobectomy to reduce the duration of the operation, due to an intraoperative fall of oxygen saturation. All of the children had an uneventful clinical course postoperatively. The alveolar diameters of the cases with CLE were significantly greater than those of the control patients. We think that the majority of cases with CLE have too severe respiratory distress to avoid surgical removal of affected lobe. Conservative management should be reserved only for patients with milder symptoms or no distress at all.
