The first case of documented Covid-19 reinfection in Israel.

We describe the first documented case of Covid-19 reinfection in Israel, out of only a handful such case worldwide, in a 20 year old otherwise healthy young woman. In the first occasion she was mildly symptomatic, whereas the second episode was apparently asymptomatic, except for tachycardia of 90/min, compared to 60/min in the first episode. The fact that out of 25 million infected persons worldwide only a handful of re-infected cases have been identified suggests that this is a rare phenomenon.

Reduced acute phase response to differentiate between viral and bacterial infections in children.

The objective of this study was to document the reduced acute phase response that appears in children with viral as opposed to bacterial infections. The white blood cell count (WBCC), the erythrocyte sedimentation rate (ESR), and leukocyte and erythrocyte adhesiveness/aggregation were determined in 36 children with acute bacterial infection, 29 children with viral infection, and 19 controls. A significant reduced WBCC, ESR, and leukocyte and erythrocyte adhesiveness/aggregation was noted in the children with acute viral infection as opposed to those with bacterial infection: 10,800 +/- 3600 and 20,000 +/- 10,000 cells/cm2, 29 +/- 21 and 53 +/- 35 mm Hg, 23 +/- 9 and 41 +/- 15%, and 3.

Prognostic implications of admission inflammatory profile in acute ischemic neurological events.

Objective: To reveal the potential prognostic implications of admission inflammatory markers in patients with acute ischemic neurological events.

Patients And Methods: Sixty patients with an acute ischemic neurological event who were examined within 24 h from the appearance of symptomatology. We determined the high-sensitive C-reactive protein (hs-CRP) concentrations, erythrocyte sedimentation rate (ESR), fibrinogen concentrations and degree of erythrocyte adhesiveness/aggregation.

Detection of a thrombolysis-related reduction in red blood cell adhesiveness/aggregation using a simple slide test.

Increased red cell aggregability might have unfavorable rheological effects in the microcirculation. It has been suggested that thrombolysis-related hypofibrinogenemia might be associated with a reduced erythrocyte adhesiveness/aggregation. We followed the reduction in erythrocyte adhesiveness/aggregation using a simple slide test and image analysis that measures the spaces that are formed between the aggregated erythrocytes.

The erythrocyte adhesiveness/aggregation test to reveal real-time information of rheological relevance in patients with familial and primary hypercholesterolemia before and following plasma exchange.

We applied an erythrocyte adhesiveness/aggregation test (EAAT) to a model of plasma exchange in individuals with familial and primary hypercholesterolemia. The significant (p < 0.0001) reduction in the concentration of fibrinogen by 56%, globulins by 48%, and cholesterol by 53% corresponded to the expected significant (p < 0.
