Parotitis-Like Symptoms Associated with COVID-19, France, March-April 2020.

We report the clinical features of 3 patients in France who had parotitis (inflammation of the parotid salivary glands) as a clinical manifestation of confirmed coronavirus disease. Results from magnetic resonance imaging support the occurrence of intraparotid lymphadenitis, leading to a parotitis-like clinical picture.

Cardiac magnetic resonance for assessment of cardiac involvement in Takotsubo syndrome: Do we still need contrast administration?

BACKGROUND: This study evaluated the ability of T1 and T2 mapping cardiovascular magnetic resonance to assess myocardial involvement in Takotsubo syndrome (TTS). We hypothesized that non-contrast mapping techniques can be accurate and sufficient. METHODS: We prospectively analysed 30 patients with TTS and 34 controls. CMR was performed a mean 5 days after the onset of symptoms and after a mean 3 month follow-up. RESULTS: On admission, compared to controls, TTS patients had significantly higher global T2 values (59 ± 8 ms vs 51 ± 4 ms, p < 0.001), native T1 (1053 ± 75 ms vs 960 ± 61 ms, p < 0.001) and extracellular volume (ECV) fraction (29% ± 5 vs 23% ±3, p < 0.001). The sensitivity and specificity for T2 (cut off: 56 ms) were 62% and 97% respectively; for native T1: (cut off 1011 ms) were 72% and 91% respectively; and for ECV (cut off: 27%) were 72% and 97% respectively. Combining T2 and native T1 provided the best sensitivity (91.7%) with a good specificity (88.2%). No patients had late gadolinium enhancement. Segmental analysis showed that T2, native T1 and ECV values were significantly higher in regions with wall motion abnormalities (WMA) compared to normokinetic segments (62 ± 9 ms vs 55 ± 5 ms, p < 0.001; 1060 ± 65 ms vs 1025 ± 56 ms, p = 0.02; and 34% ± 5 vs 29% ± 1, p = 0.02). At follow up, native T1 and ECV values did not normalized. CONCLUSION: In TTS patients, a non-contrast mapping technique provides a high diagnostic accuracy allowing identification of acute and persistent myocardial injury. Segmental analysis showed that myocardial injury is preferably detected in segments with WMA.
