Takotsubo syndrome is a generally reversible cardiomyopathy often related to a stressor trigger, either physical or emotional. It is estimated that this entity represents between 1 and 6% of the cases of suspected acute coronary syndrome without ST segment elevation in women. Coexistence with coronary artery disease has been a matter of long controversy. ⋯ However, due to the strong suspicion of stress cardiomyopathy, a cardiac magnetic resonance imaging with gadolinium was performed, which showed an improvement in the ejection fraction prior to revascularization with the presence of myocardial edema and absence of late gadolinium enhancement. The aforementioned characteristics led to the diagnosis of Takotsubo syndrome. The final decision of revascularization was based on the fact that the patient's principal complaint was typical anginal symptoms.

Dermatological emergencies are a frequent reason for emergency departments consultation. In order to determine the prevalence of dermatological emergencies, to describe the kind of dermatological diseases that present as emergencies, to analyze the coincidence between the diagnoses received by the patients in those cases with a previous consultations for the same cutaneous manifestation, and to analyze the behavior according to the health system segment in which they were attended: public segment and private segment; a prospective, observational, analytical, cross-sectional and multi-center study was carried out. Two thousand eight hundred one patients were included. ⋯ The consultation was due to an infectious disease in 35.5%, allergic in 29.6% and neoplastic in 8.6%; 0.7% of patients were hospitalized. In 31.7% of patients who had a previous consultation, a coincidence was found between the diagnoses made in 80.7% of those attended by a dermatologist, and 52.6% evaluated by non-dermatologist physician. The high prevalence of dermatological consultations and the existing differences in the probability of receiving an appropriate diagnosis according to the specialization of the intervening professional, show the importance of the presence of dermatology-trained physicians in the emergency area.

Observational Study
[Importance of the forewarning system and assistance center selection in acute stroke].
Acute ischemic stroke (AIS) is a time-dependent emergency, since the greatest impact depends on the time elapsed to treatment. The objective of this work was to analyze door to needle (DTN) and start treatment (STT) times and the effect of pre-notification system (PNS) and the appropriate choice of the healthcare center on these variables. An observational study with data obtained from records of patients admitted to the Stroke Unit (SU) was conducted between August 2015 to December 2019. ⋯ Average DNT with PNS and without PNS were 41 ± 23 and 81 ± 44 minutes, respectively (p = 0.001). STT on direct arrival to SU was 159 ± 59 minutes and to another center for referral was 199 ± 44 (p = 0.001). The use of a PNS and the direct choice of a center where IVT is performed significantly improve treatment.

Hydatidosis - caused by the parasite Echinococcus granulosus - is a zoonosis endemic to the province of Santa Cruz, associated with areas of livestock production. Once infected, man may remain asymptomatic for a prolonged period but the disease has an important impact on public health owing to the complexity and costs of its treatment. This study aimed at assessing the prevalence of environmental E. granulosus infection in rural and peri-urban areas of the town of Los Antiguos, through the detection of antigens in scattered canine feces, and to identify risk factors for transmission. ⋯ In turn, about half of the surveyed population ignored the modes of transmission of the infection and the measures to prevent it. This work shows a high infection index in the area and establishes a baseline for future comparisons. It also reinforces the need to implement education, prevention, and control activities at the local level - according to national program guidelines - in order to reduce the prevalence of environmental contamination of the disease.

The BCG vaccine was given for the first time in 1921, in Paris, to a newborn of a mother with tuberculosis. Between 1924 and 1960, the Pasteur Institute delivered BCG cultures to more than 50 laboratories around the world. In 1925, Dr Andrés Arena introduced the BCG seed to Argentina, where the vaccine began to be produced and applied orally to newborns. ⋯ There are currently more than 20 TB vaccine candidates under evaluation. History teaches, and the COVID-19 pandemic has confirmed, that vaccination is a fundamental instrument for the control of infectious diseases. Until a more effective vaccine becomes available, BCG will continue to be included in the Argentine National Vaccination Calendar for application to newborns.
