Summary.Objective. The aim of this study was to establish and compare diagnostic accuracy (sensitivity, specificity, and diagnostic odds ratio) of plain x-ray, ultrasonography, bone scintigraphy, computed tomography (CT), and magnetic resonance imaging (MRI) CT was 0.67 (95% CI, specificity, 0.5 (95% CI, and diagnostic odds ratio, 2.0 (95% CI,. The sensitivity of early x-ray was specificity, 0.96 (95% CI, and diagnostic odds ratio, 4.34 (95% CI,. The sensitivity of MRI was 0.81 (95% CI, specificity, 0.67 (95% CI, and diagnostic odds ratio, 8.67 (95% CI,. The sensitivity of late x-ray was 0.82 (95% CI, 0.75-0.88); specificity, 0.92 (95% CI, 0.62-1.0); and diagnostic odds ratio, 51.17 (95% CI, 6.61-2222.0). The sensitivity of bone scintigraphy was 0.81 (95% CI, specificity, 0.84 (95% CI, and diagnostic odds ratio, 22.30 (95% CI,.Conclusions. Our analysis showed that late x-ray is the most valuable radiologic method in the diagnosis of acute hematogenous osteomyelitis, but bone scintigraphy and magnetic resonance imaging are the most valuable tests at the onset of the disease.Correspondence to V.

Background: Thyroid cancer (TC) is a rare condition in children. It may be associated with radiation, iodine deficiency or familial inheritance. Aims: The objectives of this study were to analyse the prevalence and incidence trends over 3 decades and clinical features of TC in the paediatric population in Lithuania. Methods: We reviewed all TC cases diagnosed in children aged less than 18 years during the period 1980-2014 using medical records from 3 main hospitals in Lithuania where such TC cases are managed. Results: During the 35-year period (1980-2014) there were 57 cases (45 females) of TC in children in Lithuania. The mean age at the time of diagnosis was 14.51 ± 0.52 years. The crude incidence rate of TC ranged from 0 to 0.93 cases per 100,000 children per year and the mean annual increase was 5.26% (p < 0.001). Papillary carcinoma was the most common histological type (73.7%). No association was found between the incidence of TC and the reported areas of radioactive contamination after the Chernobyl accident. In total, 8.8% of patients had secondary TC after initial radiotherapy of a primary oncologic disease. Conclusion: The incidence of TC in the Lithuanian paediatric population between 1980 and 2014 ranged from 0 to 0.93 cases per 100,000 children per year and there was a 5.26% annual increase (p < 0.001), most probably related to the increased use of ultrasound testing.

Using two different early-stage cutaneous melanoma management techniques significantly more sentinel lymph nodes (p = 0.006) were detected using the two-stage surgery approach. However, there was no significant difference between the two approaches regarding the number of sentinel lymph nodes with micrometastases that were detected and excised.

Thyroid gland metastasis is rarely observed in clinical practice. In this report, we describe a case of a patient with primary lung cancer who developed massive metastasis to the thyroid over a short period. Because of rapid tumor growth, we there was a misdiagnosis between lymphoma, anaplastic and hypo pharyngeal cancer and lastly metastatic lesion.
