Giant cell tumor of bone is an intermediate, locally aggressive and rarely metastasizing, primary bone neoplasia. In recent years denosumab emerged as a treatment alternative for this pathology. The objective of this work was to analyze its indications as well as the clinical outcomes, side effects and local recurrence rates in patients diagnosed with giant cell tumor of bone, who received denosumab as neoadjuvant treatment. ⋯ Thirteen patients presented radiographic changes, and 11 showed complete histological response. A local recurrence was evidenced in 6 of 14 patients, and at least one adverse effect related to denosumab (including tumor malignancy) was identified in 7. Despite being a useful tool for treating giant cell tumor, the use of denosumab is associated with a higher rate of local recurrences and is not free of adverse effects.

The report of the preliminary data of the Argentine Registry of COVID in chronic dialysis is presented, from April 10, 2020 to April 9, 2021 and includes all dialysis centers in the country. In the study period, 36 918 prevalent patients on chronic dialysis were registered. ⋯ The population on chronic dialysis in Argentina, as shown in the rest of the world, is highly vulnerable to COVID infection, showing a lethality 12 times higher than the general population. The measures implemented in dialysis units, patient care and their family environment, and above all priority vaccination are essential in this vulnerable population of patients.

The determination of adenosine deaminase (ADA) is useful in countries where the prevalence of tuberculosis (TB) is high/ moderate. The objective of this study was to analyze the cut-off point for ADA in patients with TB at our institution. All patients with pleural effusion were included, from May 2016 to March 2019, except those with positive serology for HIV and transudates. ⋯ The area under the curve (AUC) was 0.90. In patients under 40 years old the best cut-off point was 41 U/l, below that obtained for the total study population. In our population the cut-off point for the ADA value in pleural exudate for the diagnosis of tuberculosis of 52 U/l presents the highest specificity and sensitivity.

The ABO incompatible (ABOi) living donor (LD) kidney transplant allows increasing the number of donors and reducing the time on the waiting list. The objectives of this study were to compare graft survival, patient survival, rejection risk factors and complications during the first year p ost-transplantation in patients who received an ABOi LD kidney transplant between 2014 and 2019 in our institution, matched according to sex, age and immunological risk with a control group of ABO compatible (ABOc) LD kidney transplants in the same period. Thirteen patients were included in each group. ⋯ No risk factors associated with rejection were found. Overall survival of patients was 100% in both groups, and graft survival was 92.3% in ABOi and 100% in ABOc (p = 1). ABOi kidney transplantation is an adequate feasible option in our environment for those who do not have compatible donors.

Carbapenemaseproducing bacteria are involved in infections and colonizations and associated with high morbidity and mortality. Their identification facilitates the design and implementation of interventions aimed at reducing the risk of infections and deaths. The objective of this study was to determine the prevalence of carbapenemase-producing microorganisms in the main public hospital in the city of Corrientes, Argentina, and to determine their susceptibility to antibiotics commonly used in clinical practice. ⋯ Among the microorganisms involved in infections (n = 56; 49%), most of those of the KPC type (n = 32; 57%) showed sensitivity only against amikacin (27/32; 84%), while most of those of the OXA-ACI type ( 24; 43%) showed significant sensitivity only against minocycline (17/24; 71%) and colistin (n = 19/24; 79%). This study demonstrated the presence of carbapenemase-producing microorganisms in all the investigated hospital units and a high frequency of resistance to antimicrobials commonly used in clinical practice. This information is relevant to adapt the therapeutic schemes and hygienic-sanitary measures to the local reality.
