Case Reports[Tuberculous pericarditis an infrequent extrapulmonary manifestation of TB].
Extrapulmonary tuberculosis (TB) contributes to 15% of total cases, representing a great diagnostic and therapeutic challenge. Pericardial involvement is present in 1 to 2% of TB patients and is considered an unusual presentation form of TB. We report a 67-year-old male presenting with fever and progressive dyspnea. ⋯ Therefore, an emergency pericardiectomy was performed. The pathological report of pericardial tissue showed caseating necrosis and its Koch culture was positive. The patient was treated with anti-tuberculous drugs with a favorable evolution.

[A new equation to estimate daily natriuresis from parameters in plasma and spot urine sample in the Chilean population].
Excessive sodium intake is associated with increased cardiovascular morbidity and mortality. Daily sodium intake is usually inferred from sodium excretion in a 24-hour urine collection, which is cumbersome and prone to errors. Different formulas have attempted to estimate 24-hour urinary sodium from a spot urine sample. Unfortunately, their concordances are insufficient and have not been tested in our population. ⋯ We developed a formula to accurately predict daily natriuresis in the Chilean population.

[Calorie and macronutrient intake during the first six months after bariatric surgery].
Bariatric surgery (BS) is the most effective procedure in the management of obesity, achieving a significant decrease in energy intake. ⋯ Patients subjected to BS had a low calorie and macronutrient intake in the first six postoperative months. Their calorie intake is negatively associated with weight loss, mainly during the first postoperative month.

[Overview of machine learning and its application in the management of emergency services].
The processes associated with health care generate a large amount of information that is difficult to analyze using standard statistical procedures. In this context, disciplines such as Data Science became relevant, mainly through strategies such as Machine Learning (ML). The latter groups a series of tools whose purpose is to develop algorithms to extract information from data, whether for explanation, classification, or prediction. ⋯ Also, there are difficulties in understanding these types of studies. This work tries to offer a nontechnical overview of the ML concept and its advantages for health care management. It collects examples of ML applications in emergency department management.

Case Reports[Low molecular weight heparin-induced hyperkalemia and hyponatremia. Report of one case].
Low molecular weight heparin-induced hyperkalemia is not an uncommon side effect. The development of hyponatremia is well described although it is less common. We report a 72-year-old woman with lumbar metastases who developed hyponatremia and hyperkalemia on the tenth day of hospitalization. ⋯ Enoxaparin-induced hypoaldosteronism was proposed and the drug was discontinued. After four days' persistence of the electrolyte disturbance, dexamethasone was changed to Hydrocortisone, and parameters normalized in 24 hours. The patient remained well until discharge and during outpatient control.
