Splenic abscess due to Salmonella enterica infection successfully treated with percutaneous drainage.

A 66-year-old female presented to our hospital with diffuse abdominal pain and diarrhea. An abdominal CT showed a splenic abscess of 9.9 x 6.1 x 6.5 cm. A conservative approach with US-guided percutaneous drainage and antibiotic treatment was performed successfully. Splenic abscess is a rare complication of Salmonella spp infection. In selected cases, percutaneous drainage can be performed safely with good efficacy.

Outpatient low toxic regimen with bortezomib in relapsed/refractory acute lymphoblastic leukemia in pediatrics and AYA patients: Single-center Mexican experience.

Relapsed or refractory acute lymphoblastic leukemia represents a major challenge in low- and middle-income countries where new therapies are not easily accessible. Combinations of cost-effective drugs should be considered as a bridge for hematopoietic stem cell transplantation. We retrospectively analyzed pediatric and adolescent and young adult patients who received reinduction with a protocol based on l-asparaginase, doxorubicin, vincristine, dexamethasone, and bortezomib (BZ). Fifteen patients were included. Total complete response (CR) was achieved by nine of 15 patients (60%); five patients achieved CR with negative minimal residual disease, two achieved complete morphological response (CR), and two complete morphological response without platelet recovery. Eleven patients (73%) were not hospitalized and 10 (66%) did not require any blood component transfusions. There were no cases of serious toxicity or mortality. Nine patients (60%) underwent transplant. Five-year overall survival was 40%. This BZ-based protocol is effective and safe when administered as an outpatient regimen and feasible in a low resource setting.
