It is essential to report this sporadic case of AML to provide clinicians with data for clinical decision-making, such as for risk-group stratification. Avelumab cost To the best of our knowledge, this is the first association between this translocation and this morphological subtype.

Calcinosis cutis is the deposit of insoluble calcium salts in the skin. It is classified according to its pathogenesis in dystrophic, metastatic, idiopathic, iatrogenic, and calciphylaxis. Idiopathic calcinosis is asymptomatic, occurs in healthy patients, and includes scrotal calcinosis, Winer's nodular calcinosis or subepidermal calcified nodules, and familial tumor calcinosis. The latter is a rare condition characterized by periarticular calcium deposition in normocalcemic patients with no bone connection.

The case of a 5-month-old male patient, who on the seventh day of life was hospitalized for multifactorial jaundice, late neonatal sepsis, and apnea with epileptic seizures is described. His evolution was torpid, with hospital admissions due to epileptic seizures that were difficult to manage with partial response to the use of diphenylhydantoin and electrolyte alterations. By means of exome sequencing directed, a pathogenic variant of wrong direction in FGF12 was detected and the diagnosis of early epileptic encephalopathy number 47 was confirmed. Also, the patient showed disseminated congenital dermatosis to lower extremities affecting thighs, asymptomatic, bilateral and symmetrical, constituted by hypopigmentation and fovea hard to deep palpation. The biopsy showed dystrophic calcification.

The case of an infant with deep congenital cutis calcinosis associated with a pathogenic variant in the FGF12 gene with epileptic encephalopathy is described. To date, this clinical situation has not been previously reported in the literature.

Malignant hyperthermia syndrome is a hereditary pharmacogenetic disorder of skeletal muscle characterized by hypermetabolic state related to the exposure of volatile anesthetic gases or depolarizing muscle relaxants. It is an infrequent entity that occurs in genetically predisposed individuals, with a very low incidence in pediatrics (1 in 10,000-15,000 anesthetic procedures).

We report a case of malignant hyperthermia related to exposure to sevoflurane during adenoidectomy surgery in a 6-year-old female. The patient presented with tachycardia, hypercapnia, and hyperthermia, requiring two successive doses of dantrolene sodium administration, with an adequate response to the treatment.

Malignant hyperthermia syndrome is a rare condition in pediatric patients that should be detected in early stages since it is essential to initiate the treatment as soon as possible.

The decrease of the left ventricular ejection fraction (LVEF) as consequence of a ventricular dysfunction is reported in cardiac alterations secondary to electrical injury. The focused cardiac ultrasound (FoCUS) helps to complete the clinical examination because it allows a faster non-invasive evaluation, and provides information that contributes to make better therapeutic decisions, especially those for patients in critical condition. The objective of this study was to explore the utility of creatine phosphokinase MB (CPK-MB) as a diagnostic tool of myocardial dysfunction in patients from 6 to 18 years old with electrical burn.

From November 2018 to August 2019, we conducted a transversal analytic study of 10 children with electric burn (6 to 18 years of age), in whom the percentage of LVEF was obtained through the FoCUS protocol in the first 24 hours after injury.

We found 10 cases of electrical burn injury, eight males and two females, with an average of 13 years of age. Eighty percent of these cases showed a slight decrease in LVEF (45-59%). When performing the FoCUS protocol, myocardial hypokinesia was reported in seven patients. We observed a moderate correlation between LVEF and CPK-MB levels (r = -0.671), and no correlation between LVEF and body surface area affected by the electrical burn.

The cardiac ultrasound influences decision making to improve the prognosis of these patients.

Astrocytomas are cancer tumors of the central nervous system and represent the most common type of solid tumors during human childhood. In 2016, the World Health Organization established a molecular classification system to regroup tumor entities to achieve a more accurate diagnosis and a better clinical decision-making and selection of treatment in patients with these types of tumors.

We evaluated a genotyping assay for rapid and cost-effective mutation detection in astrocytomas using TaqMan probes in an asymmetric polymerase chain reaction (PCR) assay.

Four diffuse astrocytomas (Grade II), three anaplastic astrocytomas (Grade III), and four glioblastomas (Grade IV) were sequenced, and all of them displayed the wild-type (WT) sequence. We tried to set up this melting analysis for the genotyping of pediatric astrocytomas by identifying the specific melting temperatures of the TaqMan probes due to the presence of the WT sequences in the isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) and H3.3 histone A genes (H3F3A). We used an IDH1-TaqMan probe to identify the WT status of IDH1 in two different WT deoxyribonucleic acid (DNA) templates (pilocytic and diffuse astrocytoma) and obtained four melting temperature values ranged from 65.6 to 92.2°C. Furthermore, only four out of 29 reactions displayed amplification of the DNA template. Sanger sequencing was faster and more reliable to detect the gene status in all the sequenced samples.

We conclude that conventional Sanger sequencing remains the gold standard for the genotyping of pediatric astrocytomas.
