Pulmonary arterial hypertension (PAH) is a serious disorder, more prevalent in patients infected with human immunodeficiency virus (HIV). It is not entirely clear what role is played by highly active antiretroviral therapy (HAART) in PAH development or course. Our aim was to describe PAH prevalence in a series of HIV-infected patients and identify possible links with cumulative and current use of different antiretrovirals. ⋯ PAH prevalence in our study was similar to others series. Current use of tenofovir may be associated with lower PAH prevalence.

Comparative Study Clinical Trial
[The optimal blood glucose target in critically ill patient: comparison of two intensive insulin therapy protocols].
Recent studies in critically ill patients receiving insulin intravenous therapy (IIT) have shown an increased incidence of severe hypoglycemia, while intermittent subcutaneous insulin «sliding scales» (conventional insulin therapy [CIT]) is associated with hyperglycemia. The objective of this study is to assess whether glycemic control range IIT can affect glucose levels and their variability and to compare it with CIT. ⋯ The use of IIT is useful to reduce the variability of blood glucose. Although the 140-180 mg/dL range would be more secure as to presenting greater variability and hyperglycemia, the 110-140 mg/dL range is most suitable.

Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. ⋯ The most common cause is left ventricular failure due to acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease.

Intoxications in infancy require urgent medical treatment within national health systems. In our country they represent 0.3% of paediatric urgencies. Most of them are accidental intoxications but is not infrequent to find some related to child abuse or to suicidal intentions, especially in adolescence. ⋯ In conclusion intoxication in infancy can lead to legal proceedings requiring specific actions for their protection. Both physicians and hospitals must comply with the legal requirement of the submission to the court of judicial parties. On the other hand, this information is an interesting step toward reinforcing public health surveillance.

When acute heart failure progresses and there is acute cardiogenic pulmonary edema, routine therapeutic measures should be accompanied by other measures that help to correct oxygenation of the patient. The final and most drastic step is mechanical ventilation. ⋯ The present article describes the controversies surrounding the results of this technique and discusses its indications. The article also discusses how to start non-invasive ventilation in patients with acute pulmonary edema from a practical point of view.
