Benign childhood myositis is a self-limiting inflammatory condition that primarily affects schoolaged boys during the winter months. It is associated with respiratory viral infections, such as influenza A and B viruses, respiratory syncytial virus (RSV), and Mycoplasma pneumoniae, among others. In September 2022, an epidemiological alert was raised due to a high number of reported cases in the metropolitan area of Buenos Aires. ⋯ This entity should be considered in the differential diagnosis of lower limb myalgia, difficulty walking, and functional impotence. It is necessary to establish management guidelines according to the clinic and laboratory. The search for respiratory viruses, mainly influenza, should be done taking into account the local epidemiology.

Case Reports
[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.

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.

Enteral nutrition through jejunostomy is a common practice in any general surgery service; it carries a low risk of complications and morbidity and mortality. We present the case of a patient with an immediate history of subtotal gastrectomy that began nutrition through jejunostomy and complicated with intestinal necrosis due to non-occlusive ischemia in the short period. The purpose of this work is to report on this complication, its pathophysiology and risk factors to take it into account and be able to take appropriate therapeutic action early.

Acetaminophen is a commonly used analgesic and antipyretic drug, which has experienced an increase in its consumption in recent years in our environment. There has also been an increase in the number of accidental and intentional overdoses that were treated by the health system. Its toxicity is dose-dependent and can cause fulminant liver failure, becoming one of the main reasons for liver transplantation in English-speaking countries. ⋯ She developed fulminant liver failure and metabolic acidosis, for which she underwent an emergency liver transplant due to the severity of her condition, from which she evolved favorably. The decision to perform a liver transplant in serious cases like this and under a condition of severe psychiatric vulnerability is challenging and must be carefully considered. This particular case illustrates the importance of multidisciplinary care including psychiatric evaluation in patients with acetaminophen poisoning.
