Bilateral Lower Extremity Compartment Syndrome Secondary to COVID-19 Myositis in a Young Vaccinated Woman.

Coronavirus disease 2019 (COVID-19) typically manifests with respiratory symptoms and can ultimately progress to severe multiorgan failure. Viral myositis, systemic capillary leak syndrome, and arteriovenous thrombosis are atypical manifestations of COVID-19. We present a case of a 33-year-old woman, fully vaccinated against COVID-19, who developed myositis and shock.

[Effect of spinal CSF dynamics on the subarachnoid diffusion of a substance applied close to the spinal cord].

In order to better understand the effects and side effects of intraspinal administration of morphine we studied the rostral spread of a comparable substance within the cerebrospinal fluid (CSF). This study was performed in connection with nuclear medical diagnostics ruling out possible rhinorrhoea or disturbances of CSF-circulation in 14 patients: Following lumbar intrathecal injection of the tracer 111-Indium-DTPA, the radioactivity over the medulla oblongata was measured continuously for 2 1/2 hours with a single probe scintillation counter; thereafter the distribution of activity over the total spinal canal was determined; finally the spread of activity was registered with the gamma scintillation camera in the 3rd, 24th and 48th hour. The diffusion of the tracer was followed in a model of the subarachnoid space.

[Treatment of pains from bone metastases with 90Y (author's transl)].

For palliation of pain caused by bone metastases beta radiation isotope therapy was successful. As shown in experimental work on animals bone uptake of 90Y with its shorter half-life is high when it is administered as a citrate complex. 90Y can be eluted with high purity from a 90Sr "cow".

[The radiation dose to the foetus during isotope investigations of the mother].

The radiation dose to the foetus from the application of five different 99mTechnetium compounds during isotope investigation of the mother was investigated. After i-v injection of 100 muCi (3.7 MBq) of 99mTc-compounds into pregnant rats, these were sacrificed during the first, second and third week of pregnancy and radioactivity was determined in the foetuses and in the blood and organs of the mother.

[Sequential scintigraphy of four different 99mTc human albumen preparations used for lung scanning].

The biological behaviour of four 99mTc-marked human albumen preparations, prepared by different methods, were studied by serial scintigraphy and excretion measurements. Three preparations consisted of particles of irregular albumen macroaggregates, the fourth was in the form of spherical albumen particles (microspheres). Forty-five patients with various pulmonary abnormalities were examined.
