RESUMO

BACKGROUND: Previous studies had identified genetic variants associated with Myocardial Infarction, but results are inconclusive. We examined the association between FII G20210A (rs1799963), FV G1691A (rs6025), FXIII 97G > T (rs11466016), ATR1 A1166C (rs5186) and MTHFR A1298C (rs1801131) polymorphisms and ST elevation Myocardial Infarction in young Mexican individuals. METHODS: We included a total of 350 patients with Myocardial Infarction <45 years old and 350 controls matched by age and gender. The polymorphisms were analyzed by PCR-RFLP using specific restriction enzymes. DNA fragments were separated by electrophoresis in 2% gel of agarose and visualized using SYBR green. RESULTS: The A1166C (p = 0.004) but not FXIII 97G > T (p = 0.19), G20210A (p = 0.32), G1691A (p = No significant) and A1298C (p = 0.21) polymorphisms were associated with increased risk for ST elevation Myocardial Infarction. Moreover, dyslipidemia, hypertension, smoking and family history of atherothrombotic disease were associated. CONCLUSIONS: We found that A1166C represented increased risk for ST elevation Myocardial Infarction. However, G20210A, G1691A, 97G > T, and A1298C were not associated. In addition, we had determined that Glu298Asp, PLA1/A2, TAFI Thr325Ile, ACE I/D, AGT M235T and PAI-1 4G/5G polymorphisms represented increased risk in the same group of patients. However, MTHFR C677T, AGT T174M, FV G1691A, TSP-1 N700S, MTHFR C677T and TAFI 174 M polymorphisms were no associated. Our results suggest that in young patients with ST Myocardial Infarction, those polymorphisms could contribute to premature endothelial dysfunction, atherothrombosis, vasoconstriction, increased platelet aggregation, muscle cell migration and proliferation. Further studies are required to try to better assess gene-gene and gene-modifiable factors interaction.

RESUMO

Background: Several polymorphisms had been associated with an increased risk of ischemic stroke, but results are inconclusive. The aim of this study was to examine the association between AGTR1 A1166C and TSP-1 N700S polymorphisms and ischemic stroke in a young Mexican population. Methods: In a case-control study, 250 patients ≤ 45 years of age with ischemic stroke and 250 controls matched by age and gender were included. The polymorphisms were determined in all participants by polymerase chain reaction. Results: There were statistical differences in genotype distribution (p = 0.01) and allele frequency (p = 0.001) of AGTR1 A1166C polymorphism. In contrast, there was a similar genotype distribution (p = 0.96) and allele frequency (p = 0.76) of the TSP1 N700S genetic variant between groups. Hypertension (p = 0.03), smoking (p = 0.02), and family history of atherothrombotic disease (p = 0.04) were associated with stroke, but not diabetes (p = 0.30) and dyslipidemia (p = 0.08). Conclusions: This is the first study in Mexican population to explore several genetic variants in young patients with ischemic stroke. Our results suggest that polymorphisms in the renin-angiotensin-aldosterone system could contribute to premature hypertension, endothelial dysfunction, atherothrombosis, vasoconstriction, smooth muscle cell migration, and proliferation. In contrast, polymorphisms in the coagulation factors are not associated with ischemic stroke. Environmental factors such as diabetes and dyslipidemia could be less important in the pathogenesis of ischemic stroke at a young age. We suggest that those polymorphisms should be determined in individuals with a family history of thrombosis to avoid the stroke development. Therefore, genotype-environmental combination could determine several possible phenotypes at different moments in life.

RESUMO

Inhaled medications are commonplace for administering bronchodilators, anticholinergics, and corticosteroids. While they have a defined legitimate use, they are also used in sporting events as performance-enhancing drugs. These performance enhancers can be acquired via both legal (i.e., at a pharmacy through over-the-counter medications or through a prescription) and illicit (i.e., black market and foreign pharmacies) means, thus making monitoring procurement impossible. While urine tests can detect these pharmacological agents hours after they have been inhaled, there is a significant lag time before they are observed in urine. Direct detection of these inhaled agents is complicated and requires a multiplexed approach due to the sheer number of inhaled pharmacological agents. Therefore, detection of propellants, which carry the drug into the lungs, provides a simpler path forward toward detection of broad pharmacological agents. In this paper, we demonstrate the first use of terahertz spectroscopy (THz) to detect inhaled medications in human subjects. Notably, we were able to detect and quantitate the propellant, HFA-134a, in breath up to 30 min after using an asthma inhaler, enabling the use of a point-of-care device to monitor exhaled breath for the presence of propellants. We also demonstrate via simulations that the same approach can be leveraged to detect and identify next-generation propellants, specifically HFA-152a. As a result, we provide evidence that a single point-of-care THz sensor can detect when individuals have used pressure-mediated dose inhalers (pMDIs) without further modification of the hardware.

RESUMO

OBJECTIVE: To examine the contribution the polymorphisms G20210A, G1691A and G10976A in the coagulation factors FII, FV, FVII, respectively; Glu298Asp and C677T in eNOS and 5,10 MTHFR in young Mexican population with cerebral infarction (CI). METHODS: 224 patients ≤ 45 years of age with CI and 224 controls matched by age and gender were recruited from 2006 and 2014. The polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism. RESULTS: We identified a significant difference in the genotype distribution of Glu298Asp (p = 0.001) and C677T (p = 0.01) polymorphisms between CI patients and control groups. The genotype distribution in the FII G20210A, FV G1691A and FVII G10976A polymorphisms were similar. There were independent factors for ischemic stroke: Glu298Asp and C677T polymorphisms, smoking; hypertension, and familial history of thrombotic disease. CONCLUSIONS: The Glu298Asp and C677T, but not FII G20210A, FV G1691A and FVII G10976A polymorphisms were associated with CI. Our results suggest that endothelial dysfunction and the synergist interaction with other factors such as smoking and hypertension contribute to CI in young individuals.


OBJETIVO: Examinar la contribución de los polimorfismos G20210A, G1691A y G10976A en los factores de coagulación FII, FV y FVII respectivamente; Glu298Asp y C677T en la óxido nítrico sintasa endotelial y 5,10 metilentetrahidrofolato reductasa, en población joven mexicana con infarto cerebral (IC). MÉTODO: Se incluyeron 224 pacientes ≤ 45 años de edad con diagnóstico de IC y 224 controles pareados por edad y sexo, de 2006 a 2014. Los polimorfismos fueron determinados por la técnica de reacción en cadena de la polimerasa-polimorfismos de longitud de fragmentos de restricción. RESULTADOS: Identificamos una diferencia significativa en la distribución genotípica de los polimorfismos Glu298Asp (p = 0.001) y C677T (p = 0.01) entre el grupo de pacientes con IC y el control. La distribución genotípica de los polimorfismos FII G20210A, FV G1691A y FVII G10976A fue similar entre ambos grupos. Se identificaron como factores independientes de IC los polimorfismos Glu298Asp y C677T, el tabaquismo, la hipertensión y el antecedente de familiar de enfermedad trombótica. CONCLUSIONES: Los polimorfismos Glu298Asp y C677T, pero no FII G20210A, FV G1691A y FVII G10976A, se asociaron con IC. Nuestros resultados sugieren que la disfunción endotelial en interacción sinérgica con otros factores de riesgo, como tabaquismo e hipertensión, contribuye al IC en individuos jóvenes.

RESUMO

La epilepsia es la principal causa de consulta neurológica en niños peruanos. Sin embargo, hay escasa información sobre sus características clínicas y epidemiológicas. Objetivos: Presentar las características clínicas de los niños epilépticos atendidos en el Hospital Cayetano Heredia, entre los años 2010 y 2016. Material y métodos: Se realizó un estudio observacional descriptivo, retrospectivo, tipo serie de casos, basado en las historias clìnicas de en niños menores de 14 años con diagnóstico de epilepsia, seguimiento clínico, registro electroencefalogràfico y neuroimagenes. Resultados: Se incluyeron 193 pacientes. El 47,2% (91/193) presentaron su primera crisis epiléptica antes del año de edad, cuya etiología fue secundaria en el 59,3% (54/91), destacando los factores perinatales y las malformaciones cerebrales. La etiología primaria fue más frecuente en los niños que iniciaron las crisis después del año de edad. Las crisis generalizadas se presentaron en 64,2% (124/193) sin diferencias por grupos etarios. El 69,9% (135/193) fueron controlados con un solo fármaco, en tanto que el 15% (29/193) fueron refractarios al tratamiento. La comorbilidad ocurrió en el 68,4% (132/193), siendo frecuentes el retraso del desarrollo psicomotor, el retardo mental y la parálisis cerebral. Conclusiones: La mayoría de los niños presentaron su primera crisis antes del año de edad, generalmente de causa secundaria. En los niños mayores fue prevalente la etiología primaria. La mayoría fueron controlados con monoterapia, pero se registró un porcentaje de refractariedad al tratamiento. La comorbilidad fue muy frecuente.


Epilepsy is the main cause of neurological clinical visits in Peruvian children. However, in our country, there is little information on its clinical and epidemiological characterizes. Objectives: To describe the clinical characteristics of children with epilepsy seen at the Cayetano Heredia Hospital, between 2010 and 2016. Material and Methods: A descriptive retrospective observational study was carried out, based on the clinical records of children under 14 years old with diagnosis of epilepsy, with clinical follow-up, electroencephalography and neuroimaging. Results: One hundred ninety-three patients were included. In 47.2% (91/193), the first seizure occurred before the one year of age; the etiology was secondary in 59.3% (54/91), with the main causes being perinatal events and cerebral malformations. Primary etiologies were more frequent in the children who started haviing seizures after one year of age. Generalized seizures ocurred in 64.2% (124/193) without differences by age groups. In 69.9% (135/193) seizures were controlled with a single drug while 15% (29/193) were refractory to treatment. Comorbidity occurred in 68,4% (132/193), with delays in psychomotor development, intellectual disability and cerebral palsy being frequent. Conclusions: Most children had their first seizures before the first year of age, usually with a secondary cause. In older children, the primary epilepsies were more prevalent. Monotherapy controlled the majority of children, but a percentage of refractoriness to the treatment was registered. Comorbidities were very frequent.

RESUMO

: The renin-angiotensin system plays an important role in the regulation of blood pressure and the development of coronary artery disease. The aim was to examine the association of the insertion deletion in the angiotensin-converting enzyme gene, M235T and T174M polymorphisms in the angiotensinogen gene with ST elevation acute myocardial infarction (STEAMI) in young Mexican population. We analyzed 242 unrelated patients with STEAMI 45 or less years of age, admitted to a cardiovascular intense care unit, and 242 individuals without STEAMI matched by age and sex, recruited from January 2006 and June 2013. The polymorphisms insertion deletion, M235T and T174M were determined in all participants by a polymerase chain-reaction-restriction fragment length polymorphism assay. There was a significant difference in the insertion deletion genotype distribution between two groups (P = 0.03) and a higher percentage of the T allele M235T polymorphism in the group of STEAMI patients (P = 0.02). The T174M polymorphism was not associated (P = 0.08). The insertion deletion and M235T polymorphisms, smoking, hypertension, familial history of cardiovascular disease and dyslipidemia were independent risk factors for STEAMI. Our results identified that the D allele from the insertion deletion and M235T but not T174M polymorphisms represent an independent risk factor for STEAMI in young Mexican population.

RESUMO

INTRODUCTION: The prevalence, progression rates, and outcomes affecting aviator valvular heart disease have not been extensively studied. METHODS: The U.S. Air Force (USAF) School of Aerospace Medicine's Clinical Sciences Database was used to determine prevalence and progression rates for regurgitant valvular disease. A subset of the initial population was further evaluated for risk factors that increased the likelihood of progression. Descriptive statistical analysis, analysis of variance, and t-test calculations were completed. RESULTS: There were 8475 unique aviators with some degree of valvular regurgitation for an overall prevalence of 3.0%. The mitral and aortic valves were most likely to have mild and moderate or greater regurgitation, respectively. Progression rates from mild to moderate were 8% in the aortic valve, 2% in the mitral valve, and less than 1% in the pulmonic and tricuspid valves. Progression rates from moderate to severe were over 20% for both the mitral and aortic valves. The only risk factors correlating to progression of valvular disease were lower levels of high-density lipoproteins in the mitral and aortic valves and triglycerides in the mitral valve. DISCUSSION: In USAF aviators, progression rates for mild or greater aortic valve regurgitation and moderate or greater mitral valve regurgitation are significant and should be followed closely. Classic risk factors of age, tobacco use, elevated blood pressure, and hyperlipidemia have no association with increased risk of valvular progression or rate of progression. Study outcomes validate the current USAF policy for valvular heart disease in aviators.

RESUMO

Cytogenetic studies have an important role in the evaluation of couples with repeated miscarriages and poor obstetric history. To estimate the prevalence of chromosomal abnormalities and polymorphic variants in 158 couples with repeated miscarriages, a cross-sectional study was conducted in Monterrey, Mexico from 1995 to 2003. Peripheral blood lymphocytes were cultured for chromosomal studies using standard methods. Twelve couples showed chromosomal abnormalities (7.60%), two Robertsonian translocations (1.27%), two balanced translocations (1.27%), one inversion (0.63%), and one a novel insertion (0.63%). This insertion [46, XX, ins (15;8) (q26;p11p23)] is unique, and is the third reported in association with repeated abortion. Mosaicism was observed in six couples (3.80%, three with structural abnormalities and three with numerical abnormalities). A female to male ratio of 1.4:1 was observed. In addition to these chromosomal abnormalities, polymorphic variants in constitutive heterochromatin of the 1qh+, 9qh+, and 16qh+ chromosomes were observed in 25 couples (15.82%), of the Yqh+ chromosome in 21 couples (13.29%), and of satellite in 35 couples (22.15%). In conclusion, chromosome analysis is necessary for appropriate clinical management of these patients.

RESUMO

OBJECTIVE: To ascertain the efficacy and safety of two chemotherapy regimens, one designed for adults and the other for children, in adolescent patients with acute lymphoblastic leukemia (ALL). METHODS: Between 2001-2006, we included patients aged 15-25, with de novo, Phi(-) ALL, without initial central nervous system (CNS) infiltration. Twenty patients received a chemotherapy regimen designed for children with high-risk ALL (LALIN) and twenty a regimen for adults (LALA). Both were intensive and included dexamethasone, daunorubicin, cyclophosphamide, vincristine, cytarabine, methotrexate and mercaptopurine as well as CNS prophylaxis. Elective suspension of chemotherapy occurred at two and three years respectively, in patients with continued complete remission. RESULTS: Patients in both groups were comparable in age, sex, presence and size of hepatosplenomegaly, initial leukocytes and platelet counts. Predominant in both groups was L2 morphology and B-cell CD10(+) immunophenotype. Results for the LALIN/ LALA groups were: failures 2/0 (p=0.49); relapses 0/4 (p= 0.05); therapy associated deaths 4/7 (p= 0.48); and event free survival at 70 months follow-up was 70% and 40% (p=0.12). CONCLUSIONS: In patients aged 15-25, with de novo ALL, a chemotherapy regimen designed for children had significantly less relapses than a regimen for adults. We saw no increase in toxicity in the LALIN versus the LALA group.

RESUMO

Presenta estudio clínico, prospectivo, ciego, controlado, paralelo, aleatorio. Fueron estudiados todos los pacientes que ingresaron a emergencia y al servicios de neumología del departamento de medicina interna del Hospital Escuela Oscar Danilo Rosales (HEODRA), en el período comprendido del 1 de junio al 31 de noviembre del 2003. En el estudio se encontró que predominó el sexo femenino con 16 pacientes (53.3 porciento) con respecto al sexo masculino con 14 pacientes (46.6 porciento). De estos en el grupo que se nebulizó con salbutamol más solución salina 8 eran del sexo masculino (53.3 porciento) y 7 del sexo femenino (46.7 porciento). En el grupo que se nebulizó con salbutamol más furosemida 6 eran del sexo masculino (40 porciento) y 9 del sexo femenino (60 porciento). En relación a la clasificación de la Evolución del asma antes del tratamiento en el grupo que se nebulizó con salbutamol más solución salina predomino el asma Intermitente Leve con 9 casos (60 porciento) seguido de la persistente leve y moderada con 3 casos (20 porciento) para ambos grupos. En el grupo que se nebulizó con salbutamol más furosemida hubo también una distribución similar, con 8 casos (53.3 porciento) en Intermitente Leve seguido de la Persistente Leve con 4 casos (26.7). Con relación al tratamiento que tomaban los pacientes antes de la crisis de asma bronquial predominó el uso de Spray de salbutamol en ambos grupos con 5 casos (33.4 porciento) en el grupo que se nebulizó con salbutamol más solución salina y 8 casos (53,3 porciento) en el grupo que se nebulizó con salbutamol más furosemida. En todos los pacientes que se estudiaron su condición de egreso fue el alta hospitalaria vivos y no se registró Reacciones Adversas Medicamentosas ni efectos colaterales que obligaran a suspender la terapia.Con respecto al Promedio y la Desviación Estándar al comparar ambos grupos se encontró para el grupo que se nebulizó con salbutamol más solución salina en cuanto a la Edad el promedio fue de 20.7 años para una desviación estándar de 6.43, en cuanto al Tiempo de Inicio de la crisis (horas) el promedio fue de 21.86 con una desviación estándar de 25.59. Al realizar este procedimiento con el tiempo de padecer asma (meses) el promedio fue de 116 y la desviación estándar de 75 y para la estancia hospitalaria (hora) el promedio fue de 4.2 horas y la desviación estándar de 0.67

RESUMO

Objetivo: determinar si el factor estimulante de granulocitos (FEC-G) asociado a antibióticos, en pacientes que desarrollan neutropenia febril relacionada al uso de quimioterapia, disminuye la duración de la fiebre, los días de neutropenia y la hospitalización. Diseño: el estudio fue prospectivo. Se incluyeron pacientes con leucemia aguda linfoblástica (LAL), que recibieron quimioterapia intensiva de inducción, intensificación o consolidación. Al azar, un grupo recibió: amikacinaceftriaxona; si no hubo curación después de tres días se agregó vancomicina; después de siete días, anfotericina. Otro grupo recibió, además de estos antibióticos, factor estimulante de colonias de granulocitos (FEC-G). Resultados: los grupos fueron comparables en la magnitud de la neutropenia inicial (<0.5 x 109/L), días previos con fiebre, sitio de la infección, quimioterapia recibida, gérmenes aislados, edad y sexo. Los pacientes del grupo que recibieron FEC-G, curaron en el curso de 3.1 días; en el otro grupo sucedió en 7.2 días (p= 0.0001). Al final del episodio infeccioso, la cuenta de neutrofilos, en el grupo con FEC-G fue de 1.9 x 109/L versus 0.7 x 109/L (p= 0.0009). La mortalidad fue de uno y dos casos (p= 0.46), respectivamente. La mortalidad global fue de 7.5 por ciento. Conclusiones: el tratamiento con FEC-G asociado a antibióticos de amplio espectro disminuye la duración de los días con fiebre, hospitalización y neutropenia. La frecuencia de curaciones de los episodios infecciosos no aumenta.

RESUMO

Se evalúan los resutlados de un programa selectivo de detección de la neoplasia intraepitelial de la vulva (NIV), realizada en la Consulta Externa de Ginecología del Hospatial Central Militar, a mujeres consideradas de riesgo. El método de detección aplicado fue la cromoscopía con solución de azul de toluidina, realizada cada 6 meses. Todas las pacientes con zonas toluidina positivas fueron sometida a colposcopía tomando biopsia de las zonas anormales. La biopsia fue el estudio que estableció el diagnóstico. Se realizaron 381 pruebas a 212 pacientes. Hubo 7 pruebas positivas, entre las que se diagnosticaron 21 casos de NIV. Hubo tres pacientes con NIV I que progresaron a NIV II en el periodo de observación. Los casos de NIV II 10 casos (47.7 por ciento) y NIV III cuatro casos (19.0 por ciento). Estos 21 casos de NIV representan el 9.9 por ciento de las mujeres de riesgo estudiadas y constituyen el 0.06% (6x10,000) de todas las pacientes de primera vez atendidas en la Consulta Externa de Ginecología delhospital. La incidencia de la enfermedad fue de 8.4 casos nuevos por años y su prevalencia en la comunidad estudiada de un caso por 1,200 mujeres mayores de 15 años. La evaluación de la prueba del azul de toluidina indica que, realizada en forma periódica, es altamente eficaz para la detección de la NIV por su mejor sensibilidad (100 por ciento) que especificidad (87.1 por ciento), su índice muy bajo de falsos negativos (0.0 por ciento) y su alto potencial diagnóstico (88.2 por ciento). Con esta experiencia los autores están convencidos de que este programa de detección de la NIV es benéfico y que por lo tanto debe extenderse dentro de su propia institución y a todos los hospitales.
