[A clinical teaching course for residents improves self-perception about preparation to teach].
Medical doctors need to be competent to teach patients, their families, students, and the health care team. In a previous study we determined that although the residents attach great importance to have teaching skills, they do not feel prepared to meet this role. ⋯ A clinical teaching course for residents improves their self-perception of preparation to teach and enhances motivation for clinical teaching.

Case Reports[Spontaneous activity of cutaneous nociceptors in patients with painful polyneuropathy. Report of three patients].
Painful polyneuropathy may result from selective impairment of small diameter nerve fibers, while tactile and motor functions are preserved. In these patients clinical and electrophysiological assessment is usually unrevealing. We report three patients with a pure painful polyneuropathy. ⋯ Intraneural recordings from the peroneal nerve demonstrated abnormal spontaneous activity in 8 of 17 nociceptive afferents. One of them displayed double firing reflecting impulse multiplication. These results support the notion that patients with pain or pruritus with a distal distribution similar to a polyneuropathy, could have small diameter afferent fiber damage, despite normal function of large diameter fibers.

[Airway humidification practices in Chilean intensive care units].
In patients with an artificial airway, inspired gases can be humidified and heated using a passive (heat and moisture exchange filter - HMEF), or an active system (heated humidifier). ⋯ In Chile the main method to humidify and heat inspired gases in patients with an artificial airway is the HMEF. Although there are clear indications for the use of heated humidifiers, they are seldom employed.
