RESUMO
INTRODUCTION: Although primary immune thrombocytopenia (ITP) is rare in childhood, it is the most frequent cause of thrombocytopenia. There have been attempts to establish risk factors to predict the progression of the disease in order to optimise its management, which has changed in recent years due to, among other reasons, specialised care. MATERIAL AND METHODS: A retrospective, observational and analytical study was conducted on patients diagnosed with ITP over a 3-year period in a Paediatric Haematology specialist clinic. RESULTS: From the epidemiological, clinical and analytical point of view, the characteristics of this group are similar to others. Most of the patients (23/31, 74.2%) had ITP for less than 12 months, with there being no serious complications related to the disease or the treatment received. It was established that risk factors were related to being slowly evolving (lower event-free survival (EFS)) with no statistical significance, female gender, age over 10 years, leukopenia absence of initial severe thrombocytopenia, and non-specialised care. The absence of a history of infection was significantly related to a lower EFS. CONCLUSIONS: The epidemiological and analytical risk factors for a slowly evolving ITP are the same that described in the literature. Patients treated before the beginning of specialised care also had a lower EFS. These data seem to support the current recommendation that rare diseases should be managed in specialised units.

Introducción: los supervivientes de leucemia aguda (LA) infantil presentan un riesgo incrementado de alteraciones metabólicas y cardiovasculares que aumentan su morbimortalidad a largo plazo.Objetivo: estimar la prevalencia de obesidad, resistencia a la insulina, dislipemia e hipertensión arterial como factores de riesgo cardiometabólico (FRCM) en un grupo de supervivientes de LA infantil, y analizar las posibles causas asociadas a su desarrollo.Material y métodos: estudio observacional retrospectivo en 47 supervivientes de LA tratados en un periodo de 4 años, que recibieron seguimiento durante 10 años.Resultados: el 40% de los participantes presentaron al menos un FRCM durante el seguimiento, siendo la dislipemia (aumento LDL) el más frecuente (38,3%), seguido de obesidad/sobrepeso (31,9%) y HTA sistólica (23,4%). El sexo femenino se estableció como factor de riesgo parael desarrollo de todos ellos (RR 1,6; RR 3,16; RR 1,69; p < 0,05). Ningún superviviente desarrolló diabetes mellitus, pero sí resistencia a la insulina el 19,4%. Los pacientes con leucemias de peor pronóstico presentaron mayor riesgo de desarrollar obesidad, resistencia a la insulina y aumento de LDL (RR 3,56; RR 4,08; RR 2,53; p < 0,05). Los pacientes tratados con trasplante de progenitores hematopoyéticos presentaron mayor riesgo de obesidad, aumento de LDL e HTA sistólica (RR 2,86; RR 2,39; RR 3,12; p<0,05). La radioterapia se asoció de igual modo con un incremento de resistencia a la insulina e hipertensión arterial sistólica (RR 2,47; RR 2,53; p < 0,05).Conclusiones: existe un aumento en la prevalencia de obesidad/sobrepeso, dislipemia, resistencia a la insulina y alteración de la tensión arterial sistólica en supervivientes de leucemia aguda infantil a lo largo del tiempo, especialmente en aquellos con enfermedades y tratamientos más agresivos.

Adenosquamous carcinoma is a rare colorectal tumor with few cases described in the literature; no children have been reported. A 12-year-old-girl presented tenesmus, diarrhea, and iron deficiency anemia. Intestinal bowel disease was suspected, colonoscopy and biopsy were performed and the diagnosis was a squamous cell carcinoma. Chemoradiation therapy based on last colorectal cancer guidelines was started. Complete regression of the primary tumor was observed with lymph node progression. The pathology report of the lymphadenectomy revealed metastasis of adenosquamous carcinoma, although there was not any adenomatous component in the first biopsy. The patient presented progression with liver metastases, despite stable local disease due to response to first-line treatment of the squamous component.

Klinefelter Syndrome is the most frequent cause of hypergonadotropic hypogonadism in men. A flat response at luteinizing hormone releasing hormone stimulation test could be the first sign of hypothalamic tumor in these patients. We report the case of a patient diagnosed by neonatal screening with Klinefelter Syndrome, 47 XXY, that at 17 years follow-up presents analytical modification of the response to luteinizing hormone releasing hormone stimulation test with suppressed luteinizing hormone and follicle-stimulating hormone values; lately he presents with headache and loss of left eye vision. A magnetic resonance imaging of the brain showed a mixed germ cell hypothalamus tumor, requiring surgery, chemotherapy and radiotherapy with optimal response.

El síndrome de Klinefelter es la causa más frecuente de hipogonadismo hipergonadotropo en el varón. La supresión en la respuesta al estímulo con hormona liberadora de la hormona luteinizante en estos pacientes debe hacer sospechar como posible etiología una tumoración a nivel hipotalámico. Se presenta el caso de un paciente diagnosticado a los 4 meses con síndrome de Klinefelter mediante cribado neonatal, con cariotipo 47 XXY, en el que se realizan controles clínicos y analíticos seriados y se encuentran, a los 17 años, valores suprimidos de hormona luteinizante y hormona folículo estimulante. Inicia, posteriormente, cefalea y amaurosis de ojo izquierdo, y se encuentra, en una resonancia magnética cerebral, un tumor germinal mixto a nivel hipotalámico, que precisa tratamiento quirúrgico, quimioterapia y radioterapia, con respuesta favorable.
