Review[Measurement of exhaled nitric oxide fraction in lung diseases].
Exhaled Nitric Oxide fraction measurement is a new method for the evaluation of respiratory diseases. It has good correlation with airway inflammation and decreases with the administration of corticosteroids. ⋯ It can be used routinely to evaluate the response and adherence to treatments. This article reviews the biology of Nitric Oxide, and the measurement, interpretation, and main clinical uses of Exhaled Nitric Oxide Fraction.

Adverse events associated with antimicrobial compounds in a general hospital in Chile.
Antimicrobial compounds are associated with a wide range of adverse events (AE) and some of them can be potentially preventable. ⋯ Antimicrobial AE involved a wide diversity of compounds, occurred in different hospitalization units, affected patients of a wide age range and attacked different systems or organs. An important fraction was potentially avoidable.

Case Reports[Intestinal relapse of a cutaneous melanoma. Report of one case].
Digestive tract primary melanoma is uncommon. However, metastatic lesions are more frequent and occur mainly in the small intestine. We report a 69-year-old male patient who consulted for a hyperpigmented skin lesion on the left thigh associated with multiple subcutaneous nodules. ⋯ Laparoscopic resection with primary anastomosis was performed with good clinical evolution. The definitive biopsy showed a melanoma metastasis with two of three lymph nodes positive for metastasis and a non-mutated BRAF gene. In conclusion, a single intestinal recurrence of melanoma is rare and requires an active search, since it can be resected using minimally invasive techniques.

Case Reports[True posterior infarction diagnosis. Report of three cases].
Acute Coronary Syndrome with ST segment elevation requires rapid reperfusion, which is why the timely identification of these conditions, based on the patient's symptoms and the correct interpretation of the EKG, is essential for therapeutic decisions. We report three patients with True Posterior Infarction and their difficult EKG diagnosis. The classic 12-lead EKG method is often not capable of supporting the diagnosis, so we recommend the use of posterior leads and mirror images observing inverted V1-V2-V3 leads on the classic EKG.
