International Society of Paediatric Oncology (SIOP) Global Mapping Programme: Latin American Society of Pediatric Oncology (SLAOP) country-level report.

BACKGROUND: Latin American countries are improving childhood cancer care, showing strong commitment to implement the Global Initiative for Childhood Cancer, but there are scant publications of the situation at a continental level. METHODS: As part of the International Society of Paediatric Oncology Global Mapping project, delegates of each country participating in the Latin American Society of Pediatric Oncology (SLAOP) and chairs of national pediatric oncology societies and cooperative groups were invited to provide information regarding availability of national pediatric cancer control programs (NPCCP), pediatric oncology laws, pediatric oncology tumor registries, and training programs and support to diagnosis and treatment. RESULTS: Nineteen of the 20 countries participating in SLAOP responded. National delegates reported nine countries with NPCCP and four of them were launched in the past 5 years. National pediatric tumor registries are available in eight countries, and three provided published survival results. Fellowship programs for training pediatric oncologists are available in 12 countries. National delegates reported that eight countries provide support to most essential diagnosis and treatments and 11 provide partial or minimal support that is supplemented by civil society organizations. Seven countries have a pediatric oncology law. There are three international cooperative groups and four national societies for pediatric oncology. CONCLUSION: Despite many challenges, there were dramatic advances in survivorship, access to treatment, and availability of NPCCP in Latin America. Countries with highest social development scores in general provide more complete support and are more likely to have NPCCP, training programs, and reported survival results.

Cardiovascular risk in Cuban adolescents and young adults with congenital adrenal hyperplasia.

BACKGROUND: Hyperandrogenism and supraphysiologic glucocorticoid replacement may lead to subclinical atherosclerosis in people with congenital adrenal hyperplasia (CAH) and predispose the development of cardiovascular diseases from an early age. OBJECTIVES: To determine if cardiometabolic risk factors and subclinical atherosclerosis are more frequent in patients with CAH due to 21-hydroxylase deficiency (21OHD) and if there is an association with clinical, hormonal and treatment of 21OHD. MATERIAL AND METHODS: A descriptive prospective cross-sectional study exploring clinical variables, biochemical, hormonal variables, endothelial dysfunction (flow-mediated dilation < 5%) and carotid intima media thickness (≥ 95 percentile in adolescents and ≥ 75 percentile in adults) and epicardial fat. Adolescents and young patients with 21OHD were compared with controls matched by age, sex, body mass index and Tanner stage. RESULTS: Forty four subjects (22 with CAH), 36 (82%) females, with a mean age of 17.1 ± 5.5 years (range 10-30 years) were included. Family history revealed diabetes, hypertension, and hypercholesterolemia with high frequencies in both groups. The blood pressure was similar in both groups. Blood glucose levels were lower and triglycerides higher in patient (both p < 0.01). Epicardial fat was similar between groups and in patients with CAH it was related to cholesterol levels ​​(r = 0.679, p < 0.01), time since CAH diagnosis (r = 0.462, p = 0.03) and glucocorticoid dose (r = 0.499, p = 0.04). Carotid intima media thickness (CIMT) had a tendency to be increased in patients (p = 0.07) and was directly related to 17-hydroxyprogesterone (r = 0.510, p = 0.018), diastolic blood pressure (r = 0.444, p = 0.04) and the homeostatic model assessment (HOMA) index (r = 0.507, p = 0.01). Endothelial dysfunction was not different between groups. CONCLUSIONS: Some cardiometabolic risk factors were increased in patients with CAH and were associated with clinical, hormonal and treatment parameters of CAH. Cardiometabolic risk should be evaluated regularly in patients with CAH.

Common vampire bat (Desmodus rotundus) abundance and frequency of attacks to cattle in landscapes of Yucatan, Mexico.

Desmodus rotundus is one of the wild animal species that has benefitted by habitat alteration and its population has increased due to livestock activities. Common vampire bat population management has been implemented across Mexico due to the economic losses to livestock production, inflicted by vampire bat attacks and rabies transmission. Yucatan is one of the seven most impacted states in Mexico by the number of cattle rabies cases per year. However, there is little research on D. rotundus populations such as the frequency and attack patterns to cattle. This study's objective was to analyze the relationship between D. rotundus abundance and number of bovines attacked in livestock landscapes in Yucatan. The study used data gathered by the State Committee for Protection and Promotion of Livestock in Yucatan through the National Campaign for Common Vampire Bat Population Control. Data collected from January 2014 to December 2017 was analyzed using Pearson correlation. Distribution maps on Desmodus rotundus abundance and number of bovines attacked were also created. Higher abundance of Desmodus rotundus and number of cattle attacks were observed in the central region of Yucatan, particularly in Izamal municipality. Positive correlations were found between (1) abundance of Desmodus rotundus and number of cattle in the region, (2) total number of cattle and number of cattle attacked, and (3) abundance of Desmodus rotundus and number of cattle attacked. We can conclude that there is a relationship between Desmodus rotundus abundance and frequency of cattle attacks in most municipalities across Yucatan. Some outstanding exceptions were observed, which require further detailed investigations.

Changes in the Bacterial Diversity of Human Milk during Late Lactation Period (Weeks 21 to 48).

Breast milk from a single mother was collected during a 28-week lactation period. Bacterial diversity was studied by amplicon sequencing analysis of the V3-V4 variable region of the 16S rRNA gene. Firmicutes and Proteobacteria were the main phyla detected in the milk samples, followed by Actinobacteria and Bacteroidetes. The proportion of Firmicutes to Proteobacteria changed considerably depending on the sampling week. A total of 411 genera or higher taxons were detected in the set of samples. Genus Streptococcus was detected during the 28-week sampling period, at relative abundances between 2.0% and 68.8%, and it was the most abundant group in 14 of the samples. Carnobacterium and Lactobacillus had low relative abundances. At the genus level, bacterial diversity changed considerably at certain weeks within the studied period. The weeks or periods with lowest relative abundance of Streptococcus had more diverse bacterial compositions including genera belonging to Proteobacteria that were poorly represented in the rest of the samples.

Mosaicismo sexual / Sexual mosaicism

RESUMEN Los trastornos del desarrollo sexual son estados congénitos en los cuales el desarrollo del sexo cromosómico, gonadal o anatómico es atípico. Por tratarse de un caso sumamente raro consideramos de interés su presentación. Se presenta adolescente masculino de 15 años, con antecedentes de genitales atípicos al nacer, desarrollo de baja talla y estigmas turnerianos, pubertad espontánea y normal. Los estudios genéticos determinaron como sexo cromosómico un mosaico 45,X/46,XY/47XYY, y sexo molecular varón. Se inscribió socialmente como varón, se le realizó cirugía de reconstrucción genital y utilizó tratamiento con hormona de crecimiento biosintética que mantiene actualmente. La evolución clínica ha sido favorable con adecuada integración social. Ante la presencia de genitales atípicos al nacer se necesita de un manejo multidisciplinario. El diagnóstico etiológico de los trastornos de la diferenciación sexual requiere de una alta pericia médica. Un tratamiento integral en estos pacientes les garantiza una buena calidad de vida(AU)

ABSTRACT Sexual development´s disorders are congenital states in which the development of the chromosomal, anatomic or gonadal sex is atypical. Since this is a very rare case, we consider it as of interests for presentation. It is presented a teenager, 15-years-old male, with a history of atypical genitalia at birth, development of short height and Turner's stigmas, and spontaneous and normal puberty. The genetic studies identified as chromosomal sex a mosaic 45,X/46,XY/47XYY and male as molecular sex. He was socially registered as a male, he had a genital reconstruction surgery and he was under treatment with biosynthetic growth hormone that he currently maintains. The clinical evolution has been favourable with adequate social integration. In the presence of atypical genitalia at birth, it is needed a multidisciplinary management. The etiological diagnosis of disorders of sexual differentiation requires a high level of medical expertise. A comprehensive treatment in these patients guarantees them a good quality of life(AU)

Factores de riesgo de diabetes mellitus tipo 2 en adolescentes / Risk factors for type 2 diabetes mellitus in adolescentes

RESUMEN Fundamento: La creciente prevalencia de diabetes mellitus tipo 2 (DM2) desde las edades pediátricas, ha convertido a la morbimortalidad relacionada con ella en un problema importante de salud pública. La detección precoz de factores de riesgo de DM2 en adolescentes, permitiría realizar acciones preventivas con enfoque de riesgo, que conducirían a disminuir la incidencia de esta entidad, siendo un pilar fundamental de la atención primaria. Objetivo: Identificar la presencia de factores de riesgo de DM2 en adolescentes. Método: Se realizó un estudio descriptivo transversal en un área de salud (Policlínico "Raúl Gómez García") con una muestra de 96 adolescentes. Se recogieron variables como edad, sexo, antecedentes de diabetes gestacional, bajo peso al nacer, tiempo de lactancia materna, historia familiar de DM2, consumo de frutas/vegetales, actividades físicas y resultantes del examen físico. Resultados: El 62,50% de los adolescentes pertenecía al sexo femenino y la adolescencia temprana. El inadecuado consumo de frutas y vegetales con 81,25% fue el factor de riesgo más común, seguido del sedentarismo con un 45,83%. Todos los adolescentes poseían al menos un factor de riesgo, y el 72,92% poseía 3 o más con predominio en el sexo femenino (p=0,022) Conclusiones: Existe una alta frecuencia de factores de riesgo para el desarrollo de DM2 en los adolescentes, con predominio de factores modificables. La mayoría de los adolescentes poseían un riesgo metabólico incrementado al presentar 3 o más factores de riesgo, en especial las féminas.

ABSTRACT Foundation: The increasing prevalence of diabetes mellitus type 2 (DM2) from the pediatric ages, has made its morbidity and mortality a major public health problem. Early detection of DM2 risk factors in adolescents, would allow preventive actions with a risk approach, which would lead to decrease the incidence of this condition, being a fundamental pillar of primary care . Objective: To identify the presence of DM2 risk factors in adolescents. Method: A cross-sectional descriptive study was conducted in a health area ("Raúl Gómez García" Polyclinic) with a sample of 96 adolescents. Variables such as age, sex, history of gestational diabetes, low birth weight, breastfeeding time, family history of DM2, fruit / vegetable intake, physical activity and physical examination results were collected. Results: The 62.50% of the adolescents belonged to the feminine sex and the early adolescence. The inadequate consumption of fruits and vegetables with 81.25% was the most common risk factor, followed by a sedentary lifestyle with 45.83%. All adolescents had at least one risk factor, and 72.92% had 3 or more with a predominance in females (p = 0.022). Conclusion: There is a high frequency of risk factors for developing of DM2 in adolescents, with a predominance of modifiable factors. Most adolescents had an increased metabolic risk when presenting 3 or more risk factors, especially females.

Anaplastic Large Cell Lymphoma in Central America: A Report From the Central American Association of Pediatric Hematology Oncology (AHOPCA).

BACKGROUND: Although anaplastic large cell lymphoma (ALCL) is curable in high-income countries (HIC), data from low- and middle-income countries (LMIC) are lacking. We therefore conducted a retrospective study of the Central American Association of Pediatric Hematology Oncology (AHOPCA) experience in treating ALCL. PROCEDURE: We included all patients age <18 years newly diagnosed with ALCL treated between 2000 and 2013 in seven AHOPCA institutions. Retrospective data were extracted from the Pediatric Oncology Network Database. RESULTS: Thirty-one patients met inclusion criteria. Twenty-five (81%) had advanced disease (stages III and IV), six (19%) were treated on the APO (doxorubicin, prednisone, vincristine) regimen, 15 (49%) on multi-agent chemotherapy designed for T-cell lineage malignancies (GuatALCL protocol), and 10 (32%) on BFM-based treatment regimens. Five-year overall event-free survival and overall survival were, respectively, 67.1 ± 8.6% and 66.7 ± 8.7%. All 10 events occurred in patients treated on BFM-based treatment regimens or the GuatALCL protocol, none on APO treatment: two patients experienced relapse, six treatment related mortality (TRM), and two abandonment. CONCLUSIONS: Treatment of ALCL in countries with limited resources is feasible with similar outcomes as in HIC, though the causes of treatment failure differ. Less intensive regimens may be preferable in order to decrease TRM and improve outcomes. Prospective clinical trials determining the ideal treatment for LMIC children with ALCL are necessary.

Menarquia y factores asociados / Menarche and associated factors

Introducción: la menarquia es el indicador de maduración sexual más comúnmente utilizado, influida por factores genéticos y ambientales, y se asocia al riesgo de desarrollar enfermedades como la obesidad, el cáncer de mama, las enfermedades cardiovasculares, entre otras. Objetivos: caracterizar demográficamente las adolescentes en estudio; evaluarlas nutricionalmente utilizando el índice de masa corporal y la circunferencia de cintura, así como identificar la relación entre la menarquia, el color de la piel, el bajo peso al nacer, el exceso de peso corporal, la obesidad abdominal y la presencia de acantosis nigricans. Métodos: se realizó un estudio observacional, descriptivo transversal en la Secundaria Básica Urbana José María Heredia, desde junio de 2010 a enero de 2011. La población estuvo constituida por 85 adolescentes, a las cuales se les preguntó acerca de la menarquia, se les realizaron las mediciones antropométricas, y se buscó la presencia de acantosis nigricans. Resultados: la edad media de las adolescentes fue 12,05 años, de las cuales el 63,5 porciento había experimentado la menarquia, y su edad media de presentación fue de 11,00±0,801 años. El 17,6 por ciento presentó exceso corporal, el 34,1 por ciento adiposidad abdominal y el 12,9 porciento acantosis nigricans, asociadas estadísticamente con la aparición de la menarquia. Conclusiones: la mayoría de las adolescentes que habían experimentado la menarquia eran maduradoras tempranas, y de color de piel blanca; mostraron un riesgo incrementado de desarrollar exceso de peso corporal, obesidad abdominal y signos clínicos de resistencia a la insulina. La aparición de la menarquia no estuvo influida por el bajo peso al nacer(AU)

Introduction: menarche is the most common sexual maturity indicator, influenced by genetic and environmental factors and associated to the risk of developing diseases such as obesity, breast cancer, cardiovascular diseases and others. Objectives: to characterize demographically the adolescents under study; to evaluate them from the nutritional viewpoint by using the body mass index and the waist circumference, as well as to identify the association among menarche, race, low birthweight, overweight, abdominal obesity and presence of acanthosis nigricans. Methods: a cross-sectional, observational and descriptive study was conducted in Jose Maria Heredia junior high school from June 2010 to January 2011. The population was made up of 85 adolescents, who were asked about menarche, were anthropometrically measured and searched for acanthosis nigricans. Results: the average age of female adolescents was 12,05 years. Menarche was experienced by 63,5 percent of them and the average age of onset was 11,00±0,801 years. In this group, 17,6 percent presented with overweight, 34,1 percent with abdominal adiposity and 12,9 percent had acanthosis nigricans, all of these factors statistically associated with the onset of menarche. Conclusions: most of the female adolescents experienced menarche at early ages; they were Caucasians and showed a high risk of developing overweight, abdominal obesity and clinical signs of insulin-resistance. The onset of menarche was not affected by low birthweight(AU)

También se aplicó una encuesta a los padres acerca de los antecedentes patológicos familiares y algunos datos de sus hijos. Resultados: se encontró que el 20,31 por ciento de los adolescentes presentaba sobrepeso u obesidad, lo cual se relacionó de forma significativa con la presencia de hipertensión arterial y signos clínicos de resistencia insulínica. La hipertensión arterial se halló en el 9,9 por ciento de los adolescentes, sin relación con factores hereditarios. Conclusiones: la obesidad y el sobrepeso corporal constituyen un problema de salud en la población adolescente estudiada, lo cual se asocia con la presencia de hipertensión arterial y resistencia insulínica, no existió relación en su comportamiento con factores no modificables (antecedentes patológicos familiares y personales)(AU)

Introduction: the adolescence is a decisive stage with a high level of prevalence of nutritional disorders that latter remains during the adulthood and are associated with short- and long term complications. Objectives: to identify the association between excess of body weight and the interesting family pathological backgrounds and some perinatal risks, the presence of high blood pressure and its relation to the family history of high blood pressure and the increase of abdominal adiposity and finally, to identify the presence of acanthosis nigricans and its relation with the similar factors. Methods: a cross-sectional and descriptive study was conducted to characterize the nutritional status of the adolescents of the seventh grade from the José María Heredia secondary school during 2009-2020. Group included 192 adolescents who with a previous consent of parents underwent anthropometric measurements (weight, height, waist circumference and estimation of the body mass index) and also the blood pressure and search of clinical signs of insulin resistance. A survey to parents on the family pathological backgrounds and on some data of their children was applied. Results: there was that the 20,31 percent of adolescents had excess weight or obesity, which was related in a significant way to the presence of a high blood pressure and clinical signs of insulin resistance. The high blood pressure was present in the 9,9 percent of adolescents without any relation to hereditary factors. Conclusions: obesity and body excess weight are a health problem in study adolescent population, which is associated with the presence of a high blood pressure and insulin resistance; there was not relation in its behavior to non-modifiable factors (family and personal pathological backgrounds)(AU)
