Summary Aim: In order to evaluate the diagnostic efficiency of arthroscintigraphy in suspected rotator cuff ruptures this new imaging procedure was performed 20 times in 17 patients with clinical signs of a rotator cuff lesion. The scintigraphic results were compared with sonography (n = 20), contrast arthrography (n = 20) and arthroscopy (n = 10) of the shoulder joint. Methods: After performing a standard bone scintigraphy with intravenous application of 300 MBq 99m-Tc-methylene diphosphonate (MDP) for landmarking of the shoulder region arthroscintigraphy was performed after an intraarticular injection of 99m-Tc microcolloid (ALBURES 400 μCi/5 ml). The application was performed either in direct combination with contrast arthrography (n = 10) or ultrasound conducted mixed with a local anesthetic (n = 10). Findings at arthroscopical surgery (n = 10) were used as the gold standard. Results: In case of complete rotator cuff rupture (n = 5), arthroscintigraphy and radiographic arthrography were identical in 5/5. In one patient with advanced degenerative alterations of the shoulder joint radiographic arthrography incorrectly showed a complete rupture which was not seen by arthroscintigraphy and endoscopy. In 3 patients with incomplete rupture, 2/3 results were consistant. A difference was seen in one patient with a rotator cuff, that has been already revised in the past and that suffered of capsulitis and calcification. Conclusion: Arthroscintigraphy is a sensitive technique for detection of rotator cuff ruptures. Because of the lower viscosity of the active compound, small ruptures can be easily detected, offering additional value over radiographic arthrography and ultrasound, especially for evaluation of incomplete cuff ruptures.

ABSTRACT The distributions of 13 variables based on 10 laboratory tests measuring thyroid function were studied in euthyroid controls and in patients with toxic diffuse or toxic multinodular goitre. Density functions were fitted to the empirical data and the goodness of fit was evaluated by the use of the χ2-test. In a few instances there was a significant difference but the material available was in some respects too small to allow a very accurate estimation. The normal limits for each variable was defined by the 2.5 and 97.5 percentiles. It appears that in some instances these limits are too rigorous from the practical point of view. It is emphasized that the crossing point of the functions for euthyroid controls and hyperthyroid patients may be a better limit to use. In a preliminary analysis of the diagnostic efficiency the variables of total or free hormone concentration in the blood proved clearily superior to all other variables.

Abstract Cutaneous leishmaniasis (CL) is a neglected tropical disease with a wide distribution in the Americas. Brazil is an endemic country and present cases in all states. This study aimed to describe the occurrence, the underlying clinical and epidemiological factors, and the correlation of climatic variables with the frequency of reported CL cases in the municipality of Caxias, state of Maranhão, Brazil. This is a retrospective and descriptive epidemiological study based on data extracted from the Brazilian Information System of Diseases Notification, from 2007 to 2017. Maximum and minimum temperature, precipitation, and relative air humidity data were provided by the Brazilian National Institute of Meteorology. A total of 201 reported autochthonous CL cases were analyzed. The predominance of cases was observed in males (70.1%). The age range between 31 and 60 years old was the most affected, with 96 cases (47.9%). Of the total number of registered cases, 38.8% of the affected individuals were engaged in agriculture-related activities. The georeferenced distribution revealed the heterogeneity of disease occurrence, with cases concentrated in the Western and Southern regions of the municipality. An association was detected between relative air humidity (monthly mean) and the number of CL cases per month (p = 0.04). CL continues to be a concerning public health issue in Caxias. In this context, there is a pressing need to strengthen measures of prevention and control of the disease through the network of health services of the municipality, considering local and regional particularities.

Objective: efficacy evaluation of the CEUS LI RADS v2017® system for differential diagnosis of liver tumors in patients with and without cirrhosis.Materials and methods. Retrospective analysis of diagnostic results of the 165 patients with liver tumors (177 nodules) was done. All patients underwent CEUS with results interpretation in accordance to the CEUS LIRADSv2017 ® criteria. Patients were divided into 2 groups based on clinical and morphological data. Group 1 included 62 patients with cirrhosis and/or CVH. Group 2 included 110 patients without risk factors for HCC.Results. Diagnostic efficiency of CEUS LI RADS v2017® for HCC identification was: group 1 – Se – 100%, Sp – 88%, Ac – 95.5%; group 2 – Se – 100%, Sp – 68.8%, Ac – 72.7%; general group Se – 100%, Sp – 72.2%, Ac – 81.4%. In the 2nd group, 21 out of 22 neoplasms, confirmed morphologically as FNH, we classified as LR 4. By applying benign character and specific contrasting patterns of FNG, they were transferred from LR 4 to LR 3. This allowed to increase sensitivity and specificity of differential diagnosis in group 2 (Se – 100%, Sp – 90.6%, Ac – 91.8%) and in general group (Se – 100%, Sp – 90.1%, Ac – 93.2%). Diagnostic efficiency of the criteria for non hepatocellular malignant neoplasms (LR M) was: group 1 – Se – 77.8%, Sp – 100%, Ac – 97%; group 2 – Se – 90%, Sp – 96.7%, Ac – 93.6%; general group- Se – 88.1%, Sp – 98.3%, Ac – 94.9%.Conclusion. Our study confirmed high accuracy of the CEUS LI RADS v2017® system in the differential diagnosis of focal liver tumors. Modification of the system (in particular, transfer of typical FNG forms from the LR 4 category) will make it possible to increase the accuracy of diagnostics by 20%. It will allow to use the LI RADS v2017® system for interpretation CEUS not only among patients with liver cirrhosis, but also in a general group without risk factors of GCC.
