In this case report, a 19-year-old woman suffered a high-energy trauma to her left side with multiple left-sided fractures, including ribs 8-12, with no pneumothorax on the left side, but a large right-sided pneumothorax. Contralateral pneumothorax is extremely rare in primarily unilateral trauma, especially when no contralateral rib fractures are present. A possible explanation is that of a barotrauma due to increased intrathoracic pressure with external compression. Careful examination of both sides of the body is necessary when evaluating patients with unilateral trauma, as serious organ injury may occur contralaterally., (Published under Open Access CC-BY-NC-BD 4.0. https://creativecommons.org/licenses/by-nc-nd/4.0/.)

Intrauterine hormonal contraception devices are widely used among Danish women. Cases of breast cancer have been reported in women using the devices and studies have found evidence of an increased risk, but a new meta-analysis did not find an increased risk. The reported relative risks in some of the studies are numerically substantial as quoted in this review, but it is very important that physicians take absolute numbers into account when interpreting risk in order to provide the best guidance of patients with regard to contraception and associated risks.

The aim of our study was to perform a prospective study that compared the diagnostic ability of V/Q single photon emission computer tomography (V/Q-SPECT), V/Q-SPECT combined with low-dose computed tomography (CT) and pulmonary multidetector computed tomography(MDCT)-angiography in patients suspected of having pulmonary embolism (PE) using a dedicated combined SPECT/MDCT-scanner. V/Q-SPECT in combination with low-dose CT had a sensitivity of 97% and a specificity of 100%. MDCT angiography had a sensitivity of 68% and a specificity of 100%. We conclude that V/Q-SPECT in combination with low-dose CT without contrast has an excellent diagnostic performance and should be considered the first-line imaging technique in the work-up of PE in most cases.

Mortality rates due to coronary arterial disease (CAD) have declined as result of improved prevention, diagnosis and management, but CAD remains the leading cause of death. Myocardial perfusion scintigraphy (MPS) provides a cost-effective tool for early detection of CAD in symptomatic individuals and can stratify patients according to risk of cardiac events. MPS also provides valuable information to assist clinical decision-making. A large body of evidence supports the current applications of MPS, which has become integral to several guidelines for clinical practice.

Thyrotoxic artrial fibrillation is well known and occurs in 10-30% of all patients with thyrotoxicosis. The risk of systemic embolism has been found to be 10-40% in patients with thyrotoxic atrial fibrillation. We present a case of 53 year-old man, a healthy and active athlete, with atrial fibrillation and thyrotoxicosis. He was treated with a beta-blocking agent (sotalol) and sent home. Seven days later, he suffered systemic arterial emboli, one in the right arm and one in the left leg. After embolectomy the patient started anticoagulation and no further complications occurred. Previous studies are discussed, and the following conclusions made. When taken together the data suggest that the rate of embolism in patients with thyrotoxic atrial fibrillation exceeds that of non-thyrotoxic atrial fibrillation unassociated with rheumatic heart disease. The majority of clinically evident embolic events that occur in patients with thyrotoxic atrial fibrillation involve the central nervous system. The rate of embolic events appears to be greatest early in the course of thyrotoxic atrial fibrillation, but may persist for some weeks after conversion and may be particularly high in patients with associated heart failure. It is suggested that anticoagulation therapy should be considered in these patients.
