Randomized Controlled Trial[Transesophageal echocardiography to monitor fluid administration during the perioperative period].
During the perioperative period an adequate intravascular volume must be maintained. Current recommendations overestimate perioperative volume requirements. ⋯ The use of transesophageal echocardiography significantly reduced the perioperative fluid administration.

A virtual model of fibro-bronchoscopy is reported. The virtual model represents in 3D the trachea and the bronchi creating a virtual world of the bronchial tree. ⋯ The parameters of the virtual model were gradually adjusted according to expert opinion and allowed the training of specialists with a virtual bronchoscope of great realism. The virtual bronchial tree provides clues of reality regarding the movement of the bronchoscope, creating the illusion that the virtual instrument is behaving as the real one with all the benefits in costs that this means.

Case Reports[Sub capsular splenic hematoma in a sickle cell trait carrier. Case report].
Drepanocytic anemia is an uncommon hereditary disease in Chile. The heterozygous state of drepanocytic anemia or "sickle trait" has a frequency of 8% among Afro-Americans. A small number of patients carrying hemoglobin S are homozygous, with clinical manifestations of hemolytic anemia and thrombotic disease. ⋯ Six days later, an angio CAT scan showed the presence of a subcapsular splenic hematoma that was managed conservatively. Sickle cell induction with sodium metabisulphite was positive. Hemoglobin electrophoresis confirmed the sickle trait.

[Functional endoscopic evaluation of swallowing among hospitalized patients].
Swallowing disorders are common in hospitalized patients. Functional endoscopic evaluation of swallowing (FEES) is a simple, safe and effective test for the diagnosis and monitoring of these disorders. ⋯ Most hospitalized patients with swallowing disorders achieve oral feeding before leaving hospital. Safe oral feeding is delayed as swallowing disorder is of greater severity.

Nocturnal sleep patterns may be a contributing factor for the epidemic of obesity. Epidemiologic ana experimental studies have reported that sleep restriction is an independent risk factor for weight gain and obesity. Moreover, sleep restriction is significantly associated with incidence and prevalence of obesity and several non-transmissible chronic diseases. ⋯ All these changes could result in a positive energy balance, leading to weight gain and a higher obesity risk in the long-term. The present article summarizes the epidemiologic and experimental evidence related to sleep deprivation and higher obesity risk. The possible mechanisms are highlighted.
