Severe Health Problem

AbstractAlveolar echinococcus (AE) is a severe health problem in endemic areas. In recent years, the incidence of this disease in China has been increasing. The study was designed to illustrate the multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) features of extrahepatic AE. A cohort of 33 patients who suffered from extrahepatic AE was enrolled consecutively from January 2012 to December 2017. The MSCT and MRI features of extrahepatic AE were recorded and analyzed by experienced radiologists. All cases secondary to hepatic AE, except two primary extrahepatic AE, were found in this study. Locations of extrahepatic AE included 19 (57.6%) lung, 10 (30.3%) adrenal gland, 9 (27.3%) brain, 5 (15.2%) peritoneal cavity, 5 (15.2%) spleen, 4 (12.1%) diaphragm, 3 (9.1%) kidney, 3 (9.1%) retroperitoneal, and 2 (6.1%) vertebra; Involvement of 1 (3.0%) heart, 1 (3.0%) mediastinum, 1 (3.0%) muscle, and 1 (3.0%) pancreas was rare. AE of the lung usually appeared as irregular and scattered nodules with small vacuoles or cavities inside and peripheral distribution. Multiple cerebral nodules with calcification and surrounding edema were the most common features seen in brain AE. Adrenal gland AE presented as plaques containing different sizes of hypodense areas and different amounts of calcification. Injection of contrast medium showed no enhancement of lesions except in the brain. MSCT and MRI are reliable imaging methods for the diagnosis of extrahepatic AE. When one AE patient is clinically confirmed, MSCT scan from the chest to the abdomen should be performed to exclude other organs AE.

The Universe

In the article, which is the result of scientific research in recent decades, the professor points to the value of revolutionary inventions that play a huge role in the development of research, in the evolution of the universe and the brain. One such invention is the telescope. As for the brain, the introduction of research tools such as computed tomography (1972), MRI (magnetic resonance imaging), followed by EEG (electroencephalography), PET (positron emission tomography), MEG (magnetoencephalography) and more recent inventions for tracking of the eyes condition. Such discoveries in science have made the researcher wonder: does knowledge about the brain really allow us to make learning more effective? The scientist provides a classification of children according to their age psychological periods and the work of neurons in the brain. It is indicated that at the age of 4–5 years the network of neurons is best developed. The period of a rebellious teenager is characterized by the maturation of the brain, or the processes of strengthening between neurons. The author speaks about the importance of knowledge in the achievements of neuroeducation in order to understand the strange and most unexpected statements of our students. The article calls for monitoring the results of the latest research on the universe and on our brains. The author is convinced that in the process of teaching educators are able to make certain changes in the brains of their students.

Abstract Background. Alveolar echinococcus (AE) is a severe health problem in endemic areas. In recent years, the incidence of this disease in China has been increasing. The study was designed to illustrate the multi-slice computed tomography (MSCT) and magnetic resonance imaging (MRI) features of extrahepatic AE.Methods. A cohort of 33 patients who suffered from extrahepatic AE was enrolled consecutively from January 2012 to December 2017. The MSCT and MRI features of extrahepatic AE were recorded and analyzed by experienced radiologists. The MSCT and MRI agreements for detecting imaging features of extrahepatic AE were calculated using kappa statistics.Results. All cases secondary to hepatic AE, except two primary extrahepatic AE, were found in this study. Locations of extrahepatic AE included 19 (57.6%) lung, 10 (30.3%) adrenal gland, 9 (27.3%) brain, 5 (15.2%) peritoneal cavity, 5 (15.2%) spleen, 4 (12.1%) diaphragm, 3 (9.1%) kidney, 3 (9.1%) retroperitoneal, and 2 (6.1%) vertebra; Involvement of 1 (3.0%) heart, 1 (3.0%) mediastinum, 1 (3.0%) muscle, and 1 (3.0%) pancreas was rare. AE of the lung usually appeared as irregular and scattered nodules with small vacuoles or cavities inside and peripheral distribution. Multiple cerebral nodules with calcification and surrounding edema were the most common features seen in brain AE. Adrenal gland AE presented as plaques containing different sizes of hypodense areas and different amounts of calcification. Injection of contrast medium showed no enhancement of lesions except in the brain. Very good agreements were seen between MSCT and MR for detecting number (κ=0.841, p=0.000), border (κ=0.911, p=0.000) and size (κ=0.864, p=0.000) of extrahepatic AE.Conclusions. MSCT and MRI are reliable imaging methods for the diagnosis of extrahepatic AE. When one AE patient is clinically confirmed, MSCT scan from the head to pelvis should be performed to exclude other organs AE.
