    Abstract BACKGROUND Angiocentric centrofacial lymphomas, now known as nasal-type extranodal natural killer T-cell lymphomas, are neoplasms of highly destructive characteristics that mainly affect the nasal cavity and palate. The most frequent clinical presentation includes fever, weight loss, nasal obstruction, epistaxis, nasal or facial edema, as well as necrotic ulcers in the nasal cavity, gums, and palate. It has been found to have an important association with the Epstein-Barr virus. Diagnostic pathology could be difficult due to the typical widespread tissue necrosis. CASE REPORT A 72-year-old Caucasian male sought medical attention with a chief complaint of nasal obstruction for the past 3 years, which only responded partially to unspecific treatment. He also presented with intermittent fever and nocturnal hyperhidrosis. Physical examination with rhinoscopy demonstrated a deviated septum, congestive turbines, and fragile and pale mucous membrane with yellowish, thick mucus. The pathology report described an angiocentric centrofacial lymphoma and a positive serology for Epstein-Barr virus. CONCLUSIONS The objective of this case report was to show that this illness represents a diagnostic challenge for the treating physician. It may be concluded that despite the poor prognosis of the disease, this particular case showed slower evolution and the patient remained stable despite multiple consecutive complications.

    Abstract We present the case of a young male patient with an initial diagnosis of a rhabdomyoma that was surgically treated at a different hospital when he was 17. After a 2-year disease-free period, the patient presented another intra-cardiac mass. He refused surgical treatment and died 5 years later. Post-mortem immunochemistry studies of both tumors led to the diagnosis of a primary malignant cardiac PEComa with histopathologic characteristics that resembled a rhabdomyoma with abundant "spider cells."

    Abstract Zantedeschia aethiopica (calla lily) and Anemopsis californica (yerba mansa) are plant species capable of accumulating arsenic (As) and therefore proposed as phytoremediation for removal of As from drinking water. The effects of a continuous 6 month As exposure (34±11 μg/L) from local contaminated groundwater on the antioxidant response of Z. aethiopica and A. californica were evaluated in leaves and stems of the plants bimonthly in a subsurface flow constructed wetland. As increased the activities of the antioxidant enzymes ascorbate peroxidase, glutathione reductase and catalase where higher levels were observed in Z. aethiopica than A. californica. No significant differences were detected on lipid peroxidation levels or antioxidant capacity evaluated by ORAC and DPPH assays or total phenol contents in any part of the plant, although in general the leaves of both plants showed the best antioxidant defense against the metal. In conclusion, Z. aethiopica and A. californica were able to cope to As through induction of a more sensitive enzymatic antioxidant response mechanism.

    Abstract An adequate immune and antioxidant response is a key to the resolution of sepsis. Heme oxygenase-1 (HMOX1) is a stress protein with a polymorphic (GT)n repeat in its gene promoter that regulates its expression in response to oxidative injury, such as that present in sepsis. HMOX1 is the rate-limiting enzyme of heme degradation, and the heme breakdown products, CO, Fe, and bilirubin, are considered to be biologically active metabolites with direct or indirect antioxidant and anti-inflammatory properties. In this study, we investigated the inflammatory and antioxidant response and the relationship with the HMOX1 levels and HMOX1 polymorphism in Mexican septic pediatric patients. In a case-control pilot study, we enrolled 64 septic patients and 72 hospitalized control patients without a diagnosis of sepsis. DNA extracted from buffy coat was genotyped for HMOX1 (GT)n polymorphism by PCR and markers of antioxidant and inflammatory status were quantified in plasma by analysis of the oxygen radical absorbance capacity (ORAC), protein carbonyl (PC), interleukin (IL) 6, IL10, and HMOX1 levels. In septic children, oxidative and inflammatory markers were elevated, and HMOX1 levels were positively correlated with IL10 levels. Genotypic and allelic distribution of HMOX1 polymorphism showed no difference between groups. HMOX1 short-allele septic carriers (< 25 GT repeats) presented favorable ORAC, PC and IL10 levels. This study confirms that an active response against pediatric sepsis involves the expression of HMOX1 and IL10, suggesting that the high antioxidant status associated with HMOX1 short-allele septic carriers might provide a beneficial environment for sepsis resolution.

    Abstract Several countries around the world have faced an important obesity challenge for the past four decades as the result of an obesogenic environment. This disease has a multifactorial origin and it is associated with multiple comorbidities including type 2 diabetes, hypertension, osteoarthritis, metabolic syndrome, cancer, and dyslipidemia. With regard to dyslipidemia, hypertriglyceridemia is a well-known activator of the NLRP3 inflammasome, triggering adipokines and cytokines secretion which in addition induce a systemic inflammatory state that provides an adequate scenario for infections, particularly those mediated by viruses such as HIV, H1N1 influenza, and SARS-CoV-2. The SARS-CoV-2 infection causes the coronavirus disease 2019 (COVID-19) and it is responsible for the pandemic that we are currently living. COVID-19 causes an aggressive immune response known as cytokine release syndrome or cytokine storm that causes multiorgan failure and in most cases leads to death. In the present work, we aimed to review the molecular mechanisms by which obesity-associated systemic inflammation could cause a more severe clinical presentation of COVID-19. The SARS-CoV-2 infection could potentiate or accelerate the pre-existing systemic inflammatory state of individuals with obesity,

    Abstract Background/purpose(s): During a viral infection, the immune response is mediated by the toll-like receptors and myeloid differentiation Factor 88 (MyD88) that play an important role sensing infections such as SARS-CoV-2 which has claimed the lives of more than 6.8 million people around the world.
    Methods: We carried out a cross-sectional with a population of 618 SARS-CoV-2-positive unvaccinated subjects and further classified based on severity: 22% were mild, 34% were severe, 26% were critical, and 18% were deceased. Toll Like Receptor 7 (TLR7) single-nucleotide polymorphisms (rs3853839, rs179008, rs179009, and rs2302267) and MyD88 (rs7744) were genotyped using TaqMan OpenArray. The association of polymorphisms with disease outcomes was performed by logistic regression analysis adjusted by covariates.
    Results: A significant association of rs3853839 and rs7744 of the TLR7 and MyD88 genes, respectively, was found with COVID-19 severity. The G/G genotype of the rs3853839 TLR7 was associated with the critical outcome showing an Odd Ratio = 1.98 (95% IC = 1.04-3.77). The results highlighted an association of the G allele of MyD88 gene with severe, critical and deceased outcomes. Furthermore, in the dominant model (AG + GG vs. AA), we observed an Odd Ratio = 1.70 (95% CI = 1.02-2.86) with severe, Odd Ratio = 1.82 (95% CI = 1.04-3.21) with critical, and Odd Ratio = 2.44 (95% CI = 1.21-4.9) with deceased outcomes.
    Conclusion: To our knowledge this work represents an innovative report that highlights the significant association of TLR7 and MyD88 gene polymorphisms with COVID-19 outcomes and the possible implication of the MyD88 variant with D-dimer and IFN-α concentrations.

    Abstract Introduction: The family and psychological approaches in asthma patients are essential because a dysfunctional family can increase asthma symptoms of the sick child. Aim: To determine family functioning and classification of asthma in pediatric patients, and the condition in the areas that comprises it. Method: A cross-sectional study in asthmatic patients treated in pediatrics Regional General Hospital No. 1 between April and July 2015 was done. Asthma severity was classified in response to the GINA 2010 guide. The Dr. Emma Espejel Scale of Family Functioning was applied to the patient's family. Results: The male presented more severe asthma by 70%, especially in school age. The dysfunction of the control area of family dynamics in the Mexican family impact on the severity of asthma. Discussion and Conclusion: 50% of families with a carrier member of asthma reflect dysfunction; control area was the most affected. Family and psychological approaches in patients with asthma are basic to prevent changes in family function.
