Introduction: Despite the improvement in survival in acute lymphoblastic leukemia (ALL), there are still cases with evasion of chemotherapy-induced apoptosis. The IKK/NF-κB signaling pathway contributes to antiapoptotic gene expression. Pentoxifylline (PTX) inhibits IkB phosphorylation, blocking NF-κB and antiapoptotic activity.

This retrospective study sought to describe the clinical presentation and outcomes of children with OPG at a tertiary center in Mexico.
Methods: Consecutive patients <18 years-of-age with newly diagnosed OPG between January 2002 and December 2020 at the Hospital Civil de Guadalajara Dr.
Patients with acute promyelocytic leukemia (APL) exhibit the t(15;17)(q24.1;q21.2) translocation that produces the promyelocytic leukemia ()/retinoic acid receptor α () fusion gene.

Methods: Descriptive statistics were used to calculate rates of infection (2020-2021). RT-PCR was used to compare viral loads from October 2020 to February 2021.
Sweet syndrome (SS) is an acute febrile neutrophilic dermatosis that is histologically characterized by an infiltration of the dermis by neutrophils. A 12-year-old adolescent female patient recently diagnosed with acute promyelocytic leukemia presented with fever and was hospitalized for antibiotic management after 22 days of being treated with a treatment protocol based on daunorubicin, all-trans retinoic acid (ATRA), and prophylaxis with dexamethasone, the patient developed erythematous skin lesions located mostly on the extremities. Lesions evolved into painful subcutaneous nodules, and one lesion evolved into a 2.

Background: Severe ischemia-reperfusion injury (SIRI) seems to be the key factor that can significantly affect the function of both native kidneys and renal allografts. Therefore, the development of a successful strategy is of a paramount importance in both basic and clinical research.
Methods: To determine the effects of SIRI on the native kidney function, a murine model was planned as follows: group 1 (n = 6) mice underwent to nephrectomy plus ischemia-reperfusion injury for 30 minutes; group 2 (n = 6) mice underwent to nephrectomy without ischemia-reperfusion injury and thus served as sham controls for SIRI.
Background: Meeting the nutritional needs of pediatric patients on oncology services in low budget public hospitals of Mexico is a continuous challenge, due to its financial resources.
Objective: To evaluate the effectiveness of a nutritional strategy for children and adolescents with cancer in a public hospital of Mexico, based on a complacency diet.
Methods: Across-sectional study included 58 children and adolescents (1-18 years old).

Pentoxifylline is a xanthine that possesses antitumor properties and that can induce higher apoptosis in the leukemic cells of pediatric patients with acute lymphoblastic leukemia (ALL) during treatment with prednisone. We conducted a phase 1 pilot, controlled, randomized trial to evaluate the gene expression modified by pentoxifylline during the steroid window of induction to remission phase in patients newly diagnosed with ALL. Experimental and control treatments induced broad changes in the gene expression profile.

Background: The subjective global assessment (SGA) is a simple, sensitive tool used to identify nutritional risk. It is widely used in the adult population, but there is little evidence on its effectiveness in children with cancer.
Objective: This cross-sectional study was undertaken to demonstrate significant correlation between a simplified version of the Patient-Generated SGA (PG-SGA) and anthropometric assessment to identify nutritional status in children recently diagnosed with cancer.
Background: Acute leukemia is the most common cancer in childhood. Analyzing the spatial distribution of acute leukemia may generate the identification of risk factors.
Objective: To study the incidence rate of acute leukemia, its geographic distribution, and cluster detection in the metropolitan area of Guadalajara, Mexico.
Acute lymphoblastic leukemia (ALL) accounts for 30% of all pediatric cancers. Currently available treatments exhibit toxicity and certain patients may develop resistance. Thus, less toxic and chemoresistance-reversal agents are required.

Here we present a male patient with acute myeloid leukemia (AML) initially diagnosed as M5 and with karyotype 46,XY. After induction therapy, he underwent a HLA-matched allogeneic hematopoietic stem cell transplantation, and six years later he relapsed as AML M1 with an abnormal karyotype //47,XX,+10[2]/47,XX,+11[3]/48,XX,+10,+11[2]/46,XX[13]. Based on this, we tested the possibility of donor cell origin by FISH and molecular STR analysis.

The rationale for this Federal Government Council is to financially support the treatment of all children registered into this system. All patients are within a network of 55 public certified hospitals nationwide.

A government-subsidized national cancer treatment program was therefore created for these patients and a National Cooperative Childhood Cancer Treatment Group was consequently formed for these patients. Pediatric patients with a proven diagnosis of leukemia, lymphoma or solid tumor and who were registered in the Popular Medical Insurance (PMI) program from January 2007 to December 2010, are described in this report.

Infant acute lymphoblastic leukemia (ALL) represents poor prognosis despite intensive chemotherapy. Rearrangements of chromosome 11q23 are not observed in 34% of the cases. Infant ALL patients with t(5;15)(p15;q11-13) are rare and sporadic.

We analysed the results of three protocols from 1990 to 2005. Protocol I (1990-1996) consisted of a 2 year VAPA regime. Protocol II (1996-2003) on 1 year daunorubicin/cytarabine alternating with etoposide/cytarabine.
