In Mexico, seroprevalence of Entamoeba histolytica is 8.4%. The intestinal amebiasis in patients with acute leukemia of novo, after the start of chemotherapy (CT) in the Hematology Service of the CMN 20 de Noviembre is 12%, even if patients show a negative baseline coprological test. ⋯ Tinidazole, in patients with acute de novo leukemia who initiate induction CT, is effective in the prevention of intestinal amebiasis, during the induction stage, if administered at 2 g/day, for five days, starting on day 1 of the CT.

Few studies have assessed the economic impact of inhibitors in hemophilia A in Mexico, especially in the pediatric population. ⋯ This is the first national study to show that the presence of inhibitors in pediatric patients with hemophilia A increases the cost of the disease more than four times.

Factores asociados con deterioro cognitivo en una cohorte mexicana multicéntrica de Parkinson: estudio transversal comparativo.
Cognitive impairment is common in Parkinson's disease and represents a risk for dementia. Identifying associated factors will help implement early interventions and study its progression. ⋯ Predictive factors that were consistent with those previously reported were identified. Prospective studies are required in order to clarify the effect of type B monoamine oxidase inhibitors on cognition.

The superoxide dismutase type 1 (SOD1) gene is the first responsible gene mapped in amyotrophic lateral sclerosis type 1 (ALS1), and it codes for the enzyme SOD1, the function of which is to protect against damage mediated by free radicals deriving from oxygen. Its pathophysiological mechanism in ALS1 is related to ischemia. Several molecular studies of the SOD1 gene show that point mutations are the most frequent. ⋯ On the other hand, familial and sporadic cases have a different etiology, which is explained by molecular heterogeneity and multiple pathogenic mechanisms that lead to ALS1; oxidative stress and ischemia are not the only cause. In Mexico, ALS molecular genetics studies are scarce. Clinical studies show an increase in cytokines such as adipsin in cerebrospinal fluid.

Lysosomal acid lipase deficiency is a genetic disease with a low prevalence and high morbidity and mortality in children and adults. It is characterized by an alteration of lipid metabolism, which generates cholesterol and triglyceride esters deposits in the body. Its clinical presentation depends on enzymatic activity. ⋯ Currently, there is the option of using a recombinant enzyme, which can improve lipid and liver parameters, as well as disease progression. Establishing a timely diagnosis in order to initiate specific treatment early is imperative for the prevention of morbidity and mortality. The purpose of this work is to perform a review of the literature about lysosomal acid lipase deficiency and to guide about its pathophysiology, clinical manifestations, diagnosis and treatment.
