Esophagic atresia type and its association with heart malformations in a Northern Mexico hospital.

OBJECTIVE: To know the cardiac malformations frequency associated with esophageal atresia and its type in patients of the Children's Specialties Hospital of Chihuahua as well as related sociodemographic characteristics. METHOD: The epidemiology, clinic and evolution of patients with esophageal atresia diagnosis who were admitted to this hospital for a period of two years were studied. Variables such as sex, gestational age, birth weight, Apgar score, atresia type, associated congenital malformations, hospital complications and parental related aspects were analyzed. RESULTS: Twelve patients were studied, 50% of them were male, most of them were products of term pregnancies with adequate birth weight. There were mestizo ethnicity prevalence, young mothers children with a medium socio-economic level, without geographical predominance. 82% of the cases corresponded to type III esophageal atresia, the most frequent congenital malformations associated were cardiac in 83% of which 90% corresponded to atrial septum defects. CONCLUSIONS: Esophageal atresia is a relatively common congenital malformation of multifactorial etiology. A complete approach to patients with this pathology is necessary to identify a concomitant illness and provide adequate treatment.

Correlación de la leucocitosis y lesión intracraneal en pacientes con traumatismo craneoencefálico / Correlation of leukocytosis and intracranial injury in patients with traumatic brain injury / Correlação de leucocitose e lesão intracraniana em pacientes com traumatismo crânioencefálico

Resumen: El daño microvascular difuso se asocia a pérdida de la autorregulación vascular cerebral y a pérdida de integridad de la barrera hematoencefálica. El TCE (traumatismo craneoencefálico) está asociado a un aumento en los niveles séricos de catecolaminas. Las catecolaminas son responsables de los depósitos de neutrófilos. Las catecolaminas aumentan la cuenta leucocitaria, introduciendo las células marginadas al pool circulante. La respuesta de fase aguda también se caracteriza por leucocitosis al ingreso, por lo que es probable que la cuenta de células blancas sirva como indicador adicional al diagnóstico y pronóstico del trauma de cráneo. Material y métodos: Estudio de cohorte prospectivo longitudinal. Se incluyeron pacientes atendidos con TCE, se recopilaron estudios de imagen y de laboratorio. Resultados: De los pacientes atendidos con hemorragia subaracnoidea (HSA), se encontró a su ingreso una media de leucocitos de 17,718 10^3/µl y de 13,970 10^3/µl a las 24 horas del trauma, con una p = 0.000 y 0.001, respectivamente. En pacientes con hematoma subdural (HSD) se observó a su ingreso una media de leucocitos de 18,212 10^3/μl y de 13,319 10^3/µl a las 24 horas, con una p = 0.000 y 0.003, respectivamente. En pacientes con contusión hemorrágica se detectó a su ingreso una media de leucocitos de 13,225 10^3/µl y de 12,501 10^3/µl a las 24 horas, una p = 0.091 y 0.027, respectivamente. En pacientes con hematoma epidural (HE) se observó a su ingreso una media de leucocitos de 16,527 10^3/µl y de 13,240 10^3/µl a las 24 horas, con una p = 0.000 y 0.019, respectivamente.

Abstract: Diffuse microvascular damage is associated with loss of cerebral vascular self-regulation and loss of integrity of the blood-brain barrier. Traumatic brain injury is associated with an increase in serum levels of catecholamines. Catecholamines are responsible for neutrophil deposits. Catecholamines increase the leukocyte count by introducing the marginal cells into the circulating pool. The acute phase response is also characterized by leukocytosis on admission. Therefore, the white cell count is likely to serve as an additional indicator to the diagnosis and prognosis of TBI. Material and methods: Longitudinal prospective cohort study. Patients treated in the emergency room with TBI were included, blood test and imaging studies were collected. Results: Of the patients treated with subarachnoid hemorrhage (SAH), a mean of leukocytes on entry of 17,718 10^3/µl on admission and 13,970 10^3/µl on 24 hours of trauma, with p = 0.000 and 0.001. In patients with subdural hematoma, a mean number of leukocytes was found at 18,212 10^3/µl and 13,319 10^3/µl at 24 hours, with p = 0.000 and 0.003. For patients with hemorrhagic contusion, leukocytes were found on admission on average 13,225 10^3/µl and at 12,501 10^3/µl at 24 hours, a p = 0.091 and 0.027. In patients with epidural hematoma, a mean of 16,527 10^3/µl leukocytes was found on admission, at 24 hours 13,240 10^3/µl, with p = 0.000 and 0.019.

Kawasaki disease shock syndrome: Unique and severe subtype of Kawasaki disease.

BACKGROUND: Kawasaki disease shock syndrome (KDSS) is an uncommon presentation of Kawasaki disease (KD). KDSS has been associated with more severe markers of inflammation, coronary abnormalities and i.v. immunoglobulin (IVIG) resistance. METHODS: A retrospective, descriptive study of children with KDSS in two hospitals was performed. Relevant articles about KD and shock were collected, and demographic data, clinical presentation, laboratory variables, echocardiogram findings, treatment and special features were analyzed when available. Twelve patients diagnosed with KDSS were retrospectively reviewed from two centers in Mexico, along with 91 additional cases from the literature. RESULTS: Seventy-two patients presented with complete KD (69.9%), and 30.1% (31/103) had unusual KD manifestations. The most frequent diagnosis at the time of admission was toxic shock syndrome (TSS; n = 20). Sixteen of the 20 had coronary artery abnormalities. Overall, abnormalities in the coronary arteries were documented in 65% of the patients. The mortality rate was 6.8%. CONCLUSION: The presence of coronary aneurysms was significantly and positively correlated with male gender, IVIG resistance, inotrope treatment, cardiac failure, abdominal pain and neurological symptoms. IVIG-resistant patients had higher neutrophil : lymphocyte ratio. Abdominal symptoms, hypoalbuminemia and elevated C-reactive protein were present in almost all of the patients. Multisystem involvement with atypical presentation in KDSS is frequent. An important differential diagnosis is TSS. Mechanical ventilation, gastrointestinal and neurological symptoms were associated with IVIG resistance and the presence of coronary aneurysms. The first line of treatment includes IVIG and pulse corticosteroids; in severe cases, infliximab, anakinra, cyclosporine or plasmapheresis are alternative treatment options.

Vital Signs as Predictor Factors of Intravenous Immunoglobulin Resistance in Patients With Kawasaki Disease.

Kawasaki disease (KD) is the most common cause of acquired heart disease in children. Intravenous immunoglobulin (IVIG) may significantly lower the frequency of coronary artery complications. However, some patients do not respond to initial therapy and are at higher risk of developing coronary artery lesion. A retrospective analysis of data from 419 KD patients was performed. The patients were divided into IVIG responders (n = 318) and IVIG nonresponders (n = 101). Multivariate logistic regression analysis revealed neutrophil percentage, albumin, aspartate aminotransferase, heart rate, and body temperature were independent predictors of IVIG resistance. We generated a predictive scoring system by assigning 1 point for the presence of these parameters (neutrophil >80%, albumin <3.4 g/dL, aspartate aminotransferase >100 IU/L, heart rate >146 bpm, and body temperature >38.8°C). This scoring system had a sensitivity of 76.2% and specificity of 64.8%, and a positive predictive value of 40.1% and a negative predictive value of 89.4%. Vital signs may be helpful to detect KD patients with IVIG resistance.

Fractional exhaled nitric oxide has a good correlation with asthma control and lung function in latino children with asthma.

BACKGROUND: Although the measurement of fractional exhaled nitric oxide (FE(NO)) has been recommended for observational studies and clinical trials of asthma, FE(NO) has not been examined in studies of childhood asthma in Latin America, OBJECTIVE: To examine the relationship between FE(NO) and indicators of disease control or severity [asthma control test/childhood asthma control test (ACT/C-ACT), lung function, and exercise challenge test (ECT)] in Mexican children with persistent asthma, METHODS: Children (6-18 years of age) with persistent asthma were consecutively recruited in a tertiary asthma clinic and divided into two groups, e.g. FE(NO) < 20 parts per billion (ppb) and ≥20 ppb.Adequate FE(NO) measurements were obtained in 134 (83.2%) of 161 eligible children, RESULTS: Children with FE(NO)<20 ppb had significantly higher scores on the ACT/C-ACT than those with FE(NO) ≥ 20 ppb (median [interquartile range] :23 [20.8-25] vs. 21 [18-24], p = .002, respectively). Compared to children with FE(NO) ≥20 ppb, those with FE(NO) <20 ppb had a higher baseline predicted forced expiratory volume (FEV(1)) [94% (92.5%-99.4%) vs. 83% (81%-89.9%), p = .001] and a lower probability of having a positive ECT (42.7% vs. 71.2%, p = .001). In addition, FE(NO) was significantly inversely correlated with the participants' ACT/C-ACT score and predicted FEV1, and directly correlated with positive ECT, CONCLUSION: Among Mexican children with persistent asthma, low levels of FE(NO) ( <20 ppb) are associated with better asthma control, and higher lung function.

Modelo de intervención AFASINCA para familiares de niños con cáncer / AFASINCA intervention model for children's families with cancer

Resumen

La familia que vive la experiencia de un hijo con cáncer presenta una carga emocional y cambios importantes que requieren de la aceptación de tratamientos rigurosos, necesitan, reorganizar funciones propias del núcleo familiar, y sobre todo fortalecer las relaciones y valores; bajo esta perspectiva, la sociedad actualmente demanda mejor atención por parte del equipo de salud, con un sentid humanista. Por estas razones las enfermeras(os) tienen la responsabilidad de desarrollar conocimientos y habilidades aprendidos y proporcionar los cuidados con profesionalismo, mediante nuevas propuestas o modelos de cuidado. El objetivo principal de la familia, aún no está incorporado en la filosofía del sistema de atención pediátrica. El acercamiento a la familia con situación de un hijo o hija con cáncer es muy importante, entender sus cambios contextuales y reasegurar el ejercicio de la enfermería y la visión y prestigio de la institución por medio del Modelo de “Intervención para Afrontamiento de Familias en Situación de Niño con Cáncer” (AFASINCA).

Summary

The situation of a family in case of a son or daughter with cancer deals with an emotional load and important changes that require the acceptance of rigorous treatments, deal with important demands like material and emotional adjustments, reorganize functions, change roles, strengthen the relation and values; under this perspective, today’s society demand increasingly more and better care with a humanistic sense, in which the professional nurses should have the responsibility of developing knowledge and skills to promote their professionalism, through the creation of new proposals, guides and or ways of care. The main focus in the family is not yet incorporated in the philosophy of care within the pediatric health system. Family approach is very important in the situation of a son or daughter with cancer, understand their contextual changes and to reassure the professional exercises of nursing and the institutions vision through “the model of nursing intervention for the family coping in the situation of a son or daughter with cancer” in which I present in the annexed investigation, AFASINCA Model.

Estrés postraumático en la población pediátrica atendida en el Hospital Infantil del estado de Chihuahua, México / Posttraumatic stress disorder in a pediatric population treated at the Children's Hospital of the State of Chihuahua, Mexico

Introducción. Ante el incremento de acciones violentas de diversa índole en nuestra comunidad surge la preocupación respecto a las consecuencias psicológicas en los niños que viven algún evento traumático. Por lo anterior, el objetivo del presente estudio fue identificar los factores relacionados con el desarrollo de trastorno de estrés postraumático en la población pediátrica atendida en el área de Psicología Infantil del Hospital Infantil del estado de Chihuahua. Métodos. Se realizó un estudio transversal retrospectivo en el que se analizaron los expedientes de de pacientes atendidos en el área de psicología infantil del Hospital Infantil del estado de Chihuahua durante un periodo de 3 meses. Se realizó el estudio de frecuencias y el análisis bivariado. Resultados. Se analizaron 125 expedientes que representaron 51% del total de la consulta del Departamento de Salud Mental. De estos, 41.6% correspondieron al género masculino y 58.4% al femenino. En 52 pacientes el evento desencadenante fue la violencia, mientras que en 73 pacientes éste se debió a accidentes. La edad de los pacientes se encontró dentro del rango de los 5 y los 15 años y la mayor prevalencia entre los 5 y 7 años y medio. No se encontró asociación estadísticamente significativa entre la escolaridad de los padres, la religión de la familia ni el tipo de familia (integrada o desintegrada) con el desarrollo de trastorno de estrés postraumático. Conclusiones. El trastorno de estrés postraumático en la población pediátrica ha aumentado de forma considerable en los últimos años. La identificación adecuada de los pacientes que presentan datos sugestivos del diagnóstico es de suma importancia para poder imple-mentar terapias que permitan evitar las consecuencias psicológicas.

Background. Due to the increase in various types of violent actions in our community, there is a preoccupation regarding the psychological consequences for children who survive a traumatic event. The aim of this study was to identify factors related to the development of posttraumatic stress disorder (PTSD) in pediatric patients treated in the Department of Child Psychology at Children's Hospital of the State of Chihuahua (HIECH). Methods. We conducted a retrospective cross-sectional study examining the clinical files during a 3-month period of patients treated in the Department of Child Psychology of HIECH. The study was conducted with frequencies and bivariate analysis. Results. We analyzed a total of 125 clinical files of which 41.6% corresponded to males and 58.4% to females. In 52 patients the triggering event was a violent action, whereas in 73 patients the event was due to accidents. The age of the patients was between 5 and 15 years and the highest prevalence was found in patients between 5 and 7 years of age. No statistically significant association was found in regard to parental education, religion, or family type (integrated or disintegrated) with the development of PTSD. Conclusions. Posttraumatic stress disorder in the pediatric population has increased considerably in recent years. Proper identification of patients with data suggestive of the diagnosis is important in order to implement therapies that avoid the psychological consequences.

Seven-year incidence and progression of obesity. Characterization of body fat pattern evolution in low-income Mexico City urban population.

BACKGROUND: There are no prospective data regarding the natural history of obesity in Mexico. The objective of this research was to investigate the incidence and progression of obesity in a low-income sector of Mexico City and to characterize evolution of body fat pattern distribution. METHODS: We carried out a population-based, prospective survey. Total on-site population was 15,532 persons; we determined as eligible all 35 to 64-year-old men and nonpregnant women for a total of 3,505. We interviewed at baseline 3,319 (94.7%) individuals and examined 2,282 (65.1%). At follow-up approximately 7 years later, we interviewed 1,764 (77.3%) subjects and examined 1,594 (69.9%). Measurements for all participants included height, weight, body mass index (BMI), waist-hip circumference, and subscapular and triceps skinfold thickness. Overweight was defined as BMI > or = 25 and < or = 29.9 kg/m2, while grade 1 obesity was BMI >or = 30 and < or = 34.9 kg/m2, grade 2 was > or = 35 and < or = 39.9, and grade 3, > or = 40 kg/m2. RESULTS: At baseline, prevalence of overweight was 48.6%, and grade 1 obesity, 22.7%, grade 2, 5.1%, and grade 3 obesity was 1.4%; at follow-up, these were 45.2, 25.8, 6.6, and 2.3%, respectively. At baseline, mean BMI in women was 29.1 +/- 0.16 kg/m2 and in men, 27.3 +/- 0.15 kg/m2; at follow-up, it reached 29.4 +/- 0.17 kg/m2 in women and 27.4 +/- 0.16 kg/m2 in men. Waist circumference increased from mean of 99.7 +/- 0.44 cm in women to 101.2 +/- 0.42 cm; in men, mean waist circumference rose from 95.2 +/- 0.38 to 96.7 +/- 0.39 cm. CONCLUSIONS: The obesity epidemic in this population possesses serious proportions that increase risk for severe metabolic consequences. There is a need for intervention.
