ABSTRACT

La ictericia colest谩sica se debe a la alteraci贸n de la secreci贸n de bilirrubina conjugada; es una de las posibles causas la alteraci贸n del flujo biliar por obstrucci贸n de la v铆a biliar extrahep谩tica. El linfoma es la tercera neoplasia m谩s frecuente en pediatr铆a, mientras que los tumores pancre谩ticos son poco frecuentes y, en su mayor铆a, lesiones benignas. Las manifestaciones cl铆nicas de los tumores de localizaci贸n retroperitoneal son poco espec铆ficas y suelen ser tard铆as, por lo que la sospecha cl铆nica debe ser alta. El objetivo del siguiente trabajo es presentar el caso de un ni帽o de 7 a帽os con s铆ndrome colest谩sico en el que se hall贸 un tumor en la cabeza del p谩ncreas que comprim铆a la v铆a biliar extrahep谩tica. El diagn贸stico del tumor fue linfoma no Hodgkin (LNH). Se destaca la infrecuencia de este tumor en esta localizaci贸n en la edad pedi谩trica


Cholestatic jaundice is due to an alteration in conjugated bilirubin secretion; a possible cause is an altered bile flow resulting from an obstruction of the extrahepatic bile duct. A lymphoma is the third most common neoplasm in pediatrics, while pancreatic tumors are rare and mostly benign. The clinical manifestations of retroperitoneal tumors are not very specific and are usually late, so a high level of clinical suspicion is required. The objective of this study is to describe the case of a 7-year-old boy with cholestatic syndrome with a tumor in the head of the pancreas compressing the extrahepatic bile duct. The tumor diagnosis was non-Hodgkin lymphoma (NHL). It is worth noting that the presence of a tumor in this location in pediatric age is uncommon

ABSTRACT

Cholestatic jaundice is due to an alteration in conjugated bilirubin secretion; a possible cause is an al- tered bile flow resulting from an obstruction of the extrahepatic bile duct. A lymphoma is the third most common neoplasm in pediatrics, while pancreatic tumors are rare and mostly benign. The clinical mani- festations of retroperitoneal tumors are not very specific and are usually late, so a high level of clinical suspicion is required. The objective of this study is to describe the case of a 7-year-old boy with cholestatic syndrome with a tumor in the head of the pancreas compressing the extrahepatic bile duct. The tumor diagnosis was non-Hodgkin lymphoma (NHL). It is worth noting that the presence of a tumor in this location in pedia- tric age is uncommon.

ABSTRACT

La nefronoptisis es una enfermedad renal qu铆stica, de herencia autos贸mica recesiva, causada por mutaciones en genes que codifican prote铆nas involucradas en la funci贸n de cilios primarios, lo que resulta en enfermedad renal y manifestaciones extrarrenales como degeneraci贸n retiniana y fibrosis hep谩tica. Seg煤n la edad de desarrollo de enfermedad renal cr贸nica terminal, se describen tres formas cl铆nicas de presentaci贸n: infantil, juvenil y adolescente. El diagn贸stico se realiza por una prueba gen茅tica positiva o una biopsia de ri帽贸n que demuestre cambios tubulointersticiales cr贸nicos con un engrosamiento de las membranas basales tubulares. No existe hasta la actualidad una terapia curativa, por lo que el trasplante renal oportuno es determinante en cuanto al pron贸stico. Se presenta un paciente de 13 meses de edad con poliuria de 3 meses de evoluci贸n, insuficiencia renal, anemia y elevaci贸n de transaminasas. Con hallazgos histol贸gicos compatibles en la biopsia renal, se arrib贸 al diagn贸stico de nefronoptisis infantil, con afectaci贸n hep谩tica


Nephronophthisis is an autosomal recessive cystic kidney disease caused by mutations in genes that encode proteins involved in the primary cilia function, resulting in kidney disease and extrarenal manifestations such as retinal degeneration and liver fibrosis. According to the age of development of end-stage chronic kidney disease, three clinical forms of presentation are described: infantile, juvenile and adolescent. Diagnosis is made by a positive genetic test, or a kidney biopsy demonstrating chronic tubulointerstitial changes with thickening of the tubular basement membranes. At the moment there is no healing therapy, so early kidney transplant is a fundamental tool to improve prognosis.We present a 13-month old male patient with polyuria, kidney failure, anemia and elevated aminotransferases over three months. With compatible histological kidney biopsy, the diagnosis of infantile nephronophthisis with liver involvement was reached.

ABSTRACT

Introducci贸n: El s铆ndrome de fiebre peri贸dica, estomatitis aftosa, faringitis y adenitis es un cuadro relativamente frecuente de curso autolimitado y buen pron贸stico. Es la m谩s com煤n de las enfermedades autoinflamatorias que presentan fiebre recurrente y su etiolog铆a y fisiopatogenia permanecen inciertas. Objetivo: Describir el caso cl铆nico de un ni帽o que consult贸 por fiebre recurrente y faringitis y se arrib贸 al diagn贸stico de s铆ndrome de fiebre peri贸dica, estomatitis aftosa, faringitis y adenitis. Presentaci贸n del caso: Se trata de un paciente de 5 a帽os que consult贸 por un episodio febril acompa帽ado de faringitis y adenitis, con antecedente de m煤ltiples episodios previos. Conclusiones: El s铆ndrome fiebre peri贸dica, estomatitis aftosa, faringitis y adenitis, es una entidad de curso benigno y autolimitado que constituye la causa m谩s com煤n de fiebre recurrente con un gran impacto en la vida de los pacientes. La fisiopatogenia permanece incierta. Es destacable la sospecha cl铆nica para arribar al diagn贸stico ya que no existen en la actualidad ex谩menes complementarios espec铆ficos(AU)


Introduction: Periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome is a relatively common picture of self-limiting course and good prognosis. It is the most common of self-inflammatory diseases with recurrent fever and its etiology and physiopathology remain uncertain. Objective: Describe the clinical case of a boy who was checked due recurrent fever and pharyngitis and being diagnosed with Periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome. Case presentation: This is a 5-year-old patient who was consulted due to a febrile episode accompanied by pharyngitis and adenitis, with a history of multiple previous episodes. Conclusions: Periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome is a benign, self-limiting course entity that is the most common cause of recurrent fever with a large impact on patients' lives. Its physiopathology remains uncertain. Clinical suspicion for diagnosis is noteworthy as there are currently no specific complementary test for it(AU)

ABSTRACT

Las infecciones por Streptococcus pyogenes son frecuentes en la poblaci贸n pedi谩trica en forma de faringoamigdalitis o cuadros cut谩neos. Con menor frecuencia, se presenta con formas invasivas, tales como piomiositis o fascitis necrotizante. La mortalidad en ni帽os reportada en estas 煤ltimas es de un 7,69 %. Se presenta a una paciente de 11 a帽os con malformaci贸n venolinf谩tica subescapular que consult贸 por s铆ndrome febril asociado a dolor y aumento agudo del tama帽o de la lesi贸n. Durante la internaci贸n, se arrib贸 al diagn贸stico de piomiositis por Streptococcus pyogenes


Streptococcus pyogenes infections are common in the pediatric population in the form of tonsillopharyngitis or cutaneous disease. Less frequently, it presents with invasive forms such as pyomyositis or necrotizing fasciitis. Mortality in children is of 7 %. We present an 11-year-old patient with a subscapular venolymphatic malformation who consulted for febrile syndrome associated with pain and an acute increase in the size of the lesion. During the hospitalization, diagnosis of pyomyositis due to Streptococcus pyogenes was reached.
