BACKGROUND: Okihiro syndrome is an autosomal-dominant condition characterized by radial ray malformations associated with Duane anomaly and other clinical characteristics. SALL4 mutations have been identified in 80-90% of patients with Duane- Radial ray defects/Okihiro syndrome. We report the clinical findings and results of SALL4 sequencing from a group of Mexican patients with this disorder.

BACKGROUND: Microalbuminuria is an early marker of atherosclerosis. Ethnic differences for both conditions have been reported. We studied microalbuminuria prevalence and its association with coronary artery calcification as an early atherosclerosis marker in a Mexican-Mestizo population free of diabetes and hypertension (healthy), as well as in hypertensive and diabetic subjects. METHODS: In 1,472 adults (53.3 ± 9.4 years old, 50.3% women), anthropometric measurements, fasting blood glucose, and lipid profile were determined...

BACKGROUND: No consensus has been reached regarding the existence of gender differences during motor tasks in electroencephalography. This could lead to misinterpretation of electroencephalography clinical diagnosis and affect the calibration of brain-computer interfaces. OBJECTIVE: To assess whether there are statistically significant gender differences in electroencephalography recorded during hand movements. METHODS: Electroencephalography data were recorded from 18 women and 18 men while performing hand movements and rest...

BACKGROUND: Acute respiratory distress syndrome secondary to influenza A(H1N1)pdm09 virus is the leading cause of death among this patient population. Expanding the knowledge of its course and predictors of mortality is relevant to decision making. We aimed to describe the clinical characteristics and identify factors associated with mortality in patients with acute respiratory distress syndrome secondary to influenza A(H1N1)pdm09 during the 2013-2014 influenza season. METHODS: This is an observational study of a prospective cohort of 70 patients with acute respiratory distress syndrome and influenza A(H1N1) pdm09 seen in an academic medical center...

BACKGROUND: The rate of compliance with a gluten-free diet in patients with gluten-related disorders is unknown in most Latin American countries. OBJECTIVE: To study the adherence to a gluten-free diet of Mexican individuals with celiac disease and nonceliac gluten sensitivity at the time of their first medical and nutritional consultation at a tertiary referral center. METHODS: A cross-sectional study was performed. A specific questionnaire was used to gather information on demographics, clinical condition, and self-reported adherence to a gluten-free diet, and to determine strict compliance and intentional or inadvertent gluten consumption...

BACKGROUND: In B-cell acute lymphoblastic leukemia, one of the most frequent cytogenetic alterations is the presence of the Philadelphia chromosome. Recently, newly identified genetic alterations have been studied, among them the IKZF1 deletion. IKZF1 encodes IKAROS, a zinc finger protein that plays an important role in hematopoiesis involving the regulation process of adhesion, cellular migration, and as a tumor suppressor. OBJECTIVE: We aimed to study the impact of IKAROS deletion in the evolution and prognosis of B-cell acute lymphoblastic leukemia...

BACKGROUND: In clinical trials, new oral direct-acting antiviral agent therapies have demonstrated a high sustained virological response rate in patients with hepatitis C virus infection. We aimed to analyze the efficacy and safety data from direct-acting antiviral agent interferon-free therapy in hepatitis C virus infection in a study performed in five different clinical settings in Mexico City; four private practice sites and one academic medical center in a real-world scenario. METHODS: Eighty-one patients were treated with seven different direct-acting antiviral agent regimens, in which the end of treatment, sustained virological response at 12 weeks post-treatment, and adverse effects were evaluated...

BACKGROUND: Currently, breast cancer is the most prevalent tumor among Mexican women. Screening methods such as mammography could potentially reduce the health and economic burden of breast cancer; however, its risk-benefit balance is still unclear. OBJECTIVE: To estimate the cost-effectiveness of different breast cancer screening programs using mammography in Mexico and to contribute to the decision-making process on this preventive measure. METHODS: A simulation study was performed using population data and incidence rates...

BACKGROUND: Following the release of the initial presentation of filgrastim (granulocyte colony-stimulating factor), several biosimilars have been developed worldwide. OBJECTIVE: To study the efficacy of a Mexican biosimilar granulocyte colony-stimulating factor in a single transplant center. METHODS: In a group of 19 consecutive patients with multiple sclerosis given autografts, we employed granulocyte colony-stimulating factors to mobilize stem cells from the bone marrow to the peripheral blood, either the original granulocyte colony-stimulating factor (n = 10) or a Mexican granulocyte colony-stimulating factor biosimilar (n = 9)...

Keratitis-ichthyosis-deafness syndrome is a well-characterized disease that has been related to mutations in the GJB6 gene. Clinical features such as erythrokeratoderma, palmoplantar keratoderma, alopecia, and progressive vascularizing keratitis, among others, are well known in this entity. In this report we describe a newborn female patient diagnosed with keratitis-ichthyosis-deafness syndrome with a lethal outcome due to sepsis. The patient harbored the mutation A88V that has been previously reported in lethal cases...

INTRODUCTION: Intra-arterial chemotherapy is a novel therapeutic modality for retinoblastoma patients. Intra-arterial chemotherapy involves the administration of a super-selective drug through the ophthalmic artery, resulting in better ocular penetration and low systemic toxicity. OBJECTIVE: The aim of this report was to evaluate the feasibility of intra-arterial chemotherapy in a large referral center in Mexico City. METHODS: We included patients with bilateral retinoblastoma, one enucleation, and active disease in the other eye after at least two courses of systemic chemotherapy combined with topical treatments...

BACKGROUND: Certain HLA class II haplotypes have long been related with the risk of developing type 1 diabetes. The presence of the HLA haplotype DRB1*04/DQA1*03/DQB1*03:02, together with specific β-cell autoantibodies, contributes to the development and/or severity of insulin deficiency in type 1 diabetes. OBJECTIVE: To evaluate the association of HLA risk haplotype HLA-DRB1/-DQA1/-DQB1 with β-cell function and antibody markers in recent-onset type 1 diabetes patients, their siblings, and controls...
