Cholangiocarcinomas are primary malignant tumors of the liver that arises from the epithelium lining the small intra and extrahepatic bile ducts, and has numerous histologic types and growth patterns. At computed tomography (CT) and magnetic ressonance (MR), it has various appearences which motivated the present study;we present a case within an atypical presentation. The objective is to show the variety of differential diagnoses before an atypical aspect and the importance of the imaging methods for the diagnosis. Cholangiocarcinoma is still an uncommon neoplasm, and CT and MR are crucial for accurate diagnosis and for differentiation from other hepatic tumorous and nontumorous lesions.

The recognition of the presence of ST-segment elevation in the context of ACS （acute coronary syndrome） is fundamental for the good outcome of the case. However, some electrocardiographic patterns have been highlighted by the fact that there is no elevation, but they represent a severity similar to ACS with ST elevation. Hence, it is necessary that doctors who do the first service recognize these standards *** electrocardiographic pattern of association between the ST-segment depression and the hyperacute T waves representing myocardial infarction in the anterior wall, localizing more specifically in the anterior descending artery, now known as the De Winter pattern, was first described by Dressler, and then described by Winter six years later. Winter observed that, out of a series of 1,452 cases, 2% of patients with anterior wall infarction had the pattern of ST-segment depression, positive and symmetrical T waves, and occasionally mild ST-segment elevation at AVR derivation. Those patients are admitted to the emergency room with a typical chest pain. However, because the electrocardiographic findings of this syndrome are not known to many health professionals, in many cases the patients do not receive adequate care and have fatal outcome, since mortality is relevant in these cases. Thus, the rapid recognition of this pattern is extremely necessary for the correct and effective intervention.

Introduction: In the 1990s, the development of highly active combination antiretroviral therapy in the treatment of AIDS was highlighted. The great benefit generated by the use of this treatment was the prolongation of survival of the people who got this disease, since it is no longer considered fatal, becoming a chronic condition. Objective: To identify the prevalence of the nursing diagnosis Lack of Adherence, its defining characteristics and related factors in people living with AIDS, to investigate the association between them and the prevalence rates. Methods: Cross-sectional study with 113 patients in a hospital in northeastern Brazil. For data analysis, the test of Pearson chi-square and Fisher’s exact test were used, and also calculated the prevalence rates. Results: Lack of Adherence diagnosis was present in 69% of the sample investigated. The defining characteristics and related factors that are statistically associated with that diagnosis were: lack of adherence behavior, missing scheduled appointments, complications related to development, insufficient skills to implement the system and complex treatment system. The first two characteristics had the highest chances for the development of this diagnosis. Conclusion: The study showed that the diagnostic studied was prevalent in these patients and 3 characteristics and 2 factors showed significant association.

Cytomegalovirus is the most frequent agent of congenital viral infections,affecting approximately 0.2%-2.4%of live births in different countries[1-7].Universal screening for congenital cytomegalovirus infection in newborns is not a standard practice considering cost-benefit issues and viabil-ity of diagnostic ***,most newborns are asympto-matic and there is no effective treatment for this population[2-5].
