ABSTRACT
La aspergilosis broncopulmonar alérgica (ABPA) es una reacción de hipersensibilidad secundaria al Aspergillus fumigatus (Af) que complica la evolución en fibrosis quística (FQ). Existen pocos estudios pediátricos de su prevalencia publicados en el mundo y en Chile se desconoce. El objetivo de este trabajo fue estimar la prevalencia de ABPA en niños con FQ en un hospital de referencia, explorar factores de riesgo y describir los criterios diagnósticos, tratamiento y evolución. Se incluyeron retrospectivamente los niños con FQ atendidos en un hospital terciario en Santiago de Chile (Hospital Roberto del Río) entre los años 2011 a 2019, se identificaron aquellos con diagnóstico de ABPA. Se registraron criterios diagnósticos según la Cystic Fibrosis Foundation, presencia de factores de riesgo, tratamientos recibidos y efectos adversos. De 65 pacientes con FQ atendidos en este período, la prevalencia de ABPA fue del 12%. El promedio de edad al diagnóstico fue ± 11 años (5-17 años), predominando la edad adolescente y el género masculino. El 50% cumplieron con los criterios clásicos, el 87,5% usaron antibióticos y el 62,5% corticoides inhalados. La respuesta favorable al tratamiento inicial con corticoides y antifúngico vía oral fue 62,5%, con una exacerbación al momento del estudio. El 25% se comportaron como refractario y el 12,5% respondieron a tratamiento con pulsos de metilprednisolona. El 37,5% presentaron eventos adversos relacionados a corticoides. La prevalencia de ABPA observada es comparable a las series publicadas. Se necesitan trabajos prospectivos para conocer la prevalencia nacional y su tendencia a lo largo de los años, identificando factores de riesgo.
Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity response to Aspergillus fumigatus (Af) and worsens outcome in children with cystic fibrosis (CF). Its prevalence varies in the literature, but we do not know it in Chile. The aim of the study was to know the prevalence of ABPA in children with CF and to describe risk factors, diagnostic criteria, treatment and outcome. We included all patients with CF seen in a tertiary hospital in Santiago, Chile (Hospital Roberto del Río), between 2011 and 2019; ABPA cases (CF Foundation diagnostic criteria) were identified for the estimation of the prevalence. Risk factors, diagnostic criteria and treatment were recorded, as proposed by the Cystic Fibrosis Foundation. A total of 65 patients with CF were identified in the study period, with a prevalence of 12% (8 cases). Mean age at diagnosis ± 11 years (5-17), more frequent in adolescence and male. CF Foundation criteria diagnostic were identified in 50% of cases, with high frequency of antibiotic use (87,5%) and inhaled steroids (62,5%). Positive oral steroids and antifungal treatment response was 62,5%. Refractary response was 25% and 12,5% needed intravenous metilprednisolone pulses. A 37,5% of cases presented adverse effects to steroids. Prevalence of ABPA is comparable to literature. A prospective study is needed to identified national prevalence and trends, identifying risks factors.

Thyroid storm is a rare and potentially fatal disease characterized by severe clinical manifestations of thyrotoxicosis. The most common cause of hyperthyroidism is Graves's disease (GD) and infections are the most important precipitating factor. A woman of 33 years with history of hyperthyroidism, hypertension and morbid obesity. She was treated with propylthiouracil for one year, and then suspended controls and treatment 2 years ago. Consult for 2 weeks characterized by dyspnea, cough and expectoration, plus an episode of generalized tonic-clonic seizure. In postictal state, persists with dyspnea and chest pain, which is brought to the emergency room. It is hypotensive, with fever and tachycardia, SatO2 60% on room air. It is intubated and connected to invasive mechanical ventilation. It evolves with monomorphic ventricular tachycardia, requiring cardioversion twice, recovering sinus rhythm. Imaging studies reported bilateral lung disease. CT scan brain and lumbar punture are normal. As is treated as septic shock lung focus. Among its tests: TSH 0.01 mIU/L, T4 T 23.9 ug/dL, T4L 4.77 ng/dL, T3 5.38 ng/ml, with Wartofsky Score: 90. It is managed as TS, treatment is initiated with methimazole, Propranolol, Hydrocortisone. Thyroid ultrasound shows: Goiter with cold nodules. In addition has positive TRAb. She recovers both of system cardiovascular and their respiratory infection. The patient is prepared with amiodarone and lugol for total thyroidectomy. Concordant biopsy with GD.

The use of hypothermia after cardiac arrest caused by ventricular fibrillation is a standard clinical practice, however its use for neuroprotection has been extended to other conditions. We report a 23-year-old male with intracranial hypertension secondary to a parenchymal hematoma associated to acute hydrocephalus. An arterial malformation was found and embolized. Due to persistent intracranial hypertension, moderate hypothermia with a target temperature of 33°C was started. After 12 hours of hypothermia, intracranial pressure was controlled. After 13 days of hypothermia a definitive control of intracranial pressure was achieved. The patient was discharged 40 days after admission, remains with a mild hemiparesia and is reassuming his university studies.
