Freijo Martin Concepcion , Laura Bertholt Zuber Maria , De la Rubia Fernandez Luis , Naranjo Gonzalez Cristina

Background: Pheochromocytoma is an uncommon tumor, producer of Catecholamines and causing hypertension in childhood. It is associated to genetic alterations, generally related with RET gene disorders.Method: We present the case of a unilateral familial isolated pheochromocytoma, present in father and son, carriers of a heterozygous mutation in the VHL gene (c.235C > G; p.R79G).Case: Male, 9 years-old with history of fever, prof...

Zuber Maria Laura Bertholt , Tomas Cristina Luzuriaga , Heath Karen , Martin Concepcion Freijo , Gonzalez Cristina Naranjo

Background: Heterozygous alterations of SHOX and its regulatory region PAR1 are identified in approximately 70% of Léri-Weill dyschondrosteosis and 2–5% of idiopathic short stature cases. Identification of a SHOX mutation enables GH treatment to be offered to the patient.Objective: To evaluate the clinical characteristics of seven patients with SHOX haploinsufficiency and their evolution.Method: Retrospective analysis of ...

Increased Basal Levels of 17-Hydroxyprogesterone In The Covid ERA: Must We Change The Cut-Off Point To Request Acth Test?

Laura Bertholt Zuber M. , Alonso Rubio Pablo , Palenzuela Revuelta Inmaculada , Pozas Mariscal Sara , Lavín Gómez Bernardo , Teresa Garcia Unzueta M.

Background: 17-hydroxyprogesterone (17-OHP) basal levels greater than 2ng/ml has been related to the need to request an ACTH test to dismiss non-classic congenital adrenal hyperplasia. We have seen an increase in baseline levels in 2021 compared to 2020.Objectives: To determine how many of the tests that were requested due to a high basal 17-OHP value, were positive. Assess the need to modify the cut-off points to reques...

Neonatal Hypocalcemia Due to Maternal Hypovitaminosis D: A Cohort of Children in a Region of Northern Spain

Zuber Maria Laura Bertholt , Martin Concepcion Freijo , Arias Pilar Gortazar , Fernandez Sonia Vilanova , Santos Ana Belen Perez , Amunarriz Maria Garmendia , Revuelta Inmaculada Palenzuela

Background: Neonatal hypocalcemia is defined when the total calcium levels are under 8 mg/dl (Ionic Ca < 1.1 mmol/l) in the full-term newborn, and under 7 mg/dl (Ionic Ca < 1 mmol/l) in the preterm. The fetus entirely depends on the maternal contributions of 25-OH-vitamin D, whose levels are directly correlated with diet and solar exposure. The largest transfer in calcium and vitamin D occurs in the third trimester of gestation, so prematurity is an important risk fact...

Objective: Analyze CCH detection program results from 3 Autonomous Communities: TSH and total T4 (TT4) in dried blood spot (DBS) at initial screening (48 hours of life) and at retesting. Describe the characteristics of neonates with screening compatible with CCH. Consider whether TBG deficiency (TBGD) is an added difficulty in said study.Materials and Methods: Retrospective study (May 2016-May 2020) of all neonates ≥33 weeks and/or ≥1500 gr...
