Epidemiological Characteristics of Shiga Toxin-Producing Responsible for Infections in the Polish Pediatric Population.

Shiga toxin-producing (STEC) are zoonotic pathogens causing hemorrhagic colitis and hemolytic uremic syndrome (HUS) in children and the elderly. Stool samples were collected from 180 children hospitalized in five pediatric centers in Poland in 2018-2022. Direct / gene detection by PCR in feces and isolates was performed.

[Leukapheresis in children with chronic myeloid leukemia and pulmonary leukostasis].

We present two patients with chronic myeloid leukemia and hyperleukocytosis above 350 x 10(9)/l causing the symptoms of pulmonary leukostasis. Therapeutic leukapheresis procedures with concomitant chemotherapy were initiated within 12 hours from the diagnosis. After the therapy commencement the general condition of the patients systematically improved and leukocytosis gradually decreased from the second day of treatment with disappearance of pulmonary leukostasis symptoms.
