[Occupational medical aspects of COVID-19 pandemic containment: experiences from a large chemical company].

Introduction: With the present paper we aim to describe the experience of a large chemical company in tackling the COVID-19 pandemic. Specifically, we describe the timing and content of implemented measures and outline the course of the pandemic from the company's perspective.

Methods: We describe the infection protection measures and the pandemic course at the company's main site in Ludwigshafen (Germany) from March 2020 to May 2022.

[Subcutaneous cervical and left thoracic emphysema in a 49-year-old woman on ventilation].

We report the case of a 49-year-old woman who was admitted with community-acquired pneumonia. The medical state worsened despite administration of antibiotics. She was intubated and ventilated because of respiratory distress.

[Hyponatremia-induced life-threatening cerebral edema after ecstasy use].

Ecstasy, a psychoactive amphetamine derivative, is a popular party drug. We report the cases of 2 young adults who developed cerebral edema due to hyponatremia. One patient was released from the hospital without any sequelae, whereas the second patient died due to cerebral edema.

Treatment optimization of aortocoronary dissection as a complication after heart catheterization using coronary computerized tomographic angiography.

We present the case of a 71-year-old patient with a chronic total occlusion of the right coronary artery (RCA) resulting in a retrograde aortic dissection as a complication of coronary intervention. Acute therapy consisted of coronary stent implantation into the proximal RCA to cover the dissection's entry. One day after, computed tomography-guided angiography revealed a progression of the intramural aortic hematoma with a residual dissection at the RCA ostium.

The value of multimodality imaging for detection, characterisation and management of a wall adhering structure in the right atrium.

The case presents a wall adherent structure in the right atrium in a young patient with peripheral t-cell lymphoma followed by successful prolonged lysis therapy resulting in the resolution of the thrombus is presented. This case highlights the utility of multimodality imaging in an accurate assessment of the right atrium thrombus and the effectiveness of prolonged lysis therapy.
