Mild therapeutic hypothermia improves neurological outcomes after cardiac arrest by preserving brain function. It is currently under discussion the possibility that hypothermia may also provide a protective effect on cardiac function, in particular, by reducing the infarct size in patients with acute myocardial infarction complicated by cardiac arrest. Despite encouraging experimental and clinical data obtained so far may suggest a potential future indication in this population, routine use of therapeutic hypothermia in acute myocardial infarction patients needs further investigation and it is not currently recommended.

Comparative Study Observational Study
[Digital and forehead pulse oximetry in Intensive Care Unit. A comparison].
Pulse oximetry is now a widely available technology that provides easy and continuous reliable measurements of oxygen saturation, the percentage of O2 bound to Hb (SpO2). Pulse oximetry has become a standard monitoring not only in intensive care, but also in other clinical settings, although several factors can interfere with a correct reading, as low perfusion conditions, such as low cardiac output, vasoconstriction, hypothermia. ⋯ The result was that both the values obtained with digital and frontal pulse oximetry are accurate and reliable in comparison to EGA. In situations of hypoxia, the reliability of frontal pulse oximetry appears superior compared to digital oximetry.

The authors report on a case of incomplete atrio-ventricular block in a patient on pregabalin therapy. Pregabalin was not overdosed; renal function of the patient was normal. The effect reverted after pregabalin discontinuation.

In this article, we review the expected course of each of the 12 cranial nerves. Traditional magnetic resonance imaging depicts only the larger cranial nerves but SSFP sequences of magnetic resonance imaging are capable of depicting the cisternal segments of 12 cranial nerves and also provide submillimetric spatial resolution.

Ultrasound examination of the testis is the imaging modality of choice for the evaluation of intratesticular focal lesions. In spite of its high sensibility, eco-Doppler-elastography is lacking of specificity in discrimination between benign and malign lesions, not always allowing us to make a definitive diagnosis of malignancy. When a diagnostic doubt persists, for such lesions that are indeterminate at clinical and radiological evaluation, it is possible to recur to ultrasound-guided testicular needle biopsy. This paper describes the main application scenarios of testicular fine-needle aspiration under ultrasound guidance and the experience in our institute.
