Takotsubo syndrome, was described in Japan in 1990, it is a stress cardiomyopathy, predominantly in women, usually postmenopausal. Cardiac hypokinesia occurs, with involvement of multiple coronary territories. In intensive care unit (ICU), it is considered underdiagnosed. ⋯ The patient evolved favorably. After discharge, a normalization of the cardiac function was stated in ultrasound images. The case is of clinical importance due to the low association of these two diseases and the need to screen for cardiac involvement in severe dengue.

Dengue virus is an endemic virus in Argentina that, although it was initially considered to be non-neurotropic, it is currently recognized to be neuroinvasive; thus conditioning a prevalence of neurological manifestations of up to 15% among patients. Even being considered severe symptoms, there is underdiagnoses of dengue encephalitis due to its varied clinical presentation. ⋯ Regarding neuroimaging methods, the findings are usually varied and nonspecific, and can even be normal in up to 40-50% of cases. We present three cases of dengue encephalitis diagnosed in a university hospital in Buenos Aires, Argentina, where the clinical presentation varied from temporal-spatial disorientation to refractory convulsive status with different presentations in the cerebrospinal fluid but all with positive PCR for dengue in it and with normal neuroimaging.

[Heart failure due to arteriovenous fistula for hemodialysis. Presentation of two clinical cases].
Arteriovenous fistulas for hemodialysis create a leftto-right shunt, resulting in an average 25% increase in cardiac output and subsequent remodeling of cardiac chambers. Some of these patients may develop highoutput heart failure. In this report, we present two cases of heart failure associated with an arteriovenous fistula for hemodialysis, each showing distinct clinical outcomes following either its occlusion or cerclage. Drawing from existing medical literature, we explore potential causes that might account for the divergent clinical courses observed in these cases.

Pneumatosis intestinalis and pneumoperitoneum are not pathological entities in themselves, they are radiological signs that result from some underlying condition. In general, these are associated with serious intra-abdominal processes that result in emergency surgeries with bowel resections. Below, we present the case of an 80-year-old woman, diagnosed with stage IV breast cancer under treatment with fulvestrant and ribociclib, who was admitted to our center due to abdominal pain and vomiting. ⋯ We found no reports in the literature of pneumatosis intestinalis linked to this antineoplastic medication in humans. Probably in our case the etiology was multifactorial. It is possible that ribociclib played a role, either through an indirect mechanism associated with vomiting and immunosuppression or directly on the enterocyte due to its non-specific cellular mechanism of action.

Shared care planning (ACP) is a reflective, deliberative and structured process involving the sick person and his or her caring environment. Health professionals recognize barriers to initiating ACP.Perceived self-efficacy is one of the main predictors of success in learning processes. ⋯ We explored PCA self-efficacy in health professionals with the ACP-SEs Ar scale validated for the first time in Argentina.
