[Spontaneous pneumomediastinum during labour].

This is a case report of a 35-year-old women who had spontaneous pneumomediastinum (SPM) during the second stage of labour. Although this condition during labor is very rare, it is described in the literature as Hamman's syndrome. The symptoms are dyspnoea, chest pain and subcutaneous emphysema which leads to much more severe differential diagnoses that should be eliminated quickly.

Protein biomarkers and coronary microvascular dilatation assessed by rubidium-82 PET in women with angina pectoris and no obstructive coronary artery disease.

Background And Aims: While a plethora of biomarkers have been shown to be associated with coronary artery disease, studies assessing biomarkers in coronary microvascular dysfunction (CMD) are few. We investigated associations between cardiovascular protein biomarkers and non-endothelium dependent CMD assessed by positron emission tomography (PET).

Methods: In 97 women with angina pectoris and no significant obstructive coronary artery disease (<50% stenosis on invasive coronary angiography), CMD was defined as myocardial blood flow reserve (MBFR) < 2.
