A Novel Method for the Evaluation of Bone Marrow Samples from Patients with Pediatric B-Cell Acute Lymphoblastic Leukemia-Multidimensional Flow Cytometry.

Multicolor flow cytometry (FC) evaluation has a key role in the diagnosis and prognostic stratification of ALL. Our aim was to create new analyzing protocols using multidimensional dot-plots. Seventy-two pediatric patients with ALL were included in this single-center study.

[Recurrent acute hemorrhage in the duodenum as a symptom of Bouveret's syndrome].

The authors demonstrate on the case-history of a 51-year-old patient the rare cause of repeated haemorrhage into the digestive tract calling for emergency surgery. On operation they found as the cause a solitary biliary concrement which penetrated into the duodenum and caused haemorrhage of its wall. The disease was described in 1896 by Bouveret as a syndrome of duodenal obturation by a large gallstone.

[Antibiotic prophylaxis in thoracic surgery].

On a group of patients operated during the last three months under standard precautions the authors explain their views as regards antibiotic prophylaxis in thoracic surgery. They justify not only "short-term prophylactic administration of antibiotics" but also prolonged prophylaxis with antibiotics. Useful in this respect proved Mandol, cefalosporin of the 2nd generation, which is used as a standard drug without preoperative examination of the bacterial flora in sputum.
