Worsening of Congenital Hypothyroidism After Start of Carob-bean Gum Thickened Formula: Is There a Link? A Case Report
We describe an infant with CH whose thyroid hormone levels worsened after she started a carob-bean gum thickened formula. A baby girl was diagnosed with CH by newborn screening (at confirmatory blood evaluation TSH was 496.0 µIU/mL and FT4 0.13 ng/dl). Five weeks after beginning L-T4 treatment TSH normalized (TSH 2.72 µIU/mL , FT4 2.08 ng/dl); nevertheless, only another 5 weeks later we noticed a new worsening of thyroid hormone levels (TSH 31.1 µIU/mL , FT4 1.27 ng/dl), which worsened further (TSH 44.8 µIU/mL, FT4 1.16 ng/dl) even if L-T4 dosage was increased. Anamnesis disclosed that she had been given a carob-bean g...

Impact of Early Intervention with Triiodothyroacetic Acid on Peripheral and Neurodevelopmental Findings in a Boy with MCT8 Deficiency
J Clin Res Pediatr Endocrinol. 2023 Dec 6. doi: 10.4274/jcrpe.galenos.2023.2023-10-1. Online ahead of print.ABSTRACTMonocarboxylate transporter8 (MCT8) deficiency is a rare genetic disorder characterized by peripheral thyrotoxicosis and severe cognitive, motor disability due to cerebral hypothyroidism. 3,3',5-triiodothyroacetic acid(Triac) was shown to improve peripheral thyrotoxicosis but data on neurodevelopmental outcome are scarce. Herein a case of MCT8 deficiency and the experience with Triac focusing on change in neurodevelopmental and peripheral features are being presented. Five-month-old boy was referred for feedi...

Screening of Mutations in Maturity-onset Diabetes of the Young-related Genes and < em > RFX6 < /em > in Children with Autoantibody-negative Type 1 Diabetes Mellitus
CONCLUSION: This study screened mutations in the 14 MODY-related genes and the regulatory factor X6 (RFX6) gene in Turkish children diagnosed with autoantibody-negative type 1 diabetes mellitus (T1DM). The frequencies of the MODY subtypes differed from previous reports. Although GCK-MODY was the most frequent mutation in Turkish children, similar to previous studies, the second most prevalent MODY subtype was HNF1B-MODY. This study also established three additional novel mutations in different MODY genes.PMID:38054414 | DOI:10.4274/jcrpe.galenos.2023.2023-5-10 (Source: JCRPE Journal of Clinical Research in Pediatric Endocrinology)

Familial Clinical Heterogeneity of Medullary Thyroid Cancer with Germline RET S891A Protooncogene Mutation: 7-Year Follow-up with Successful Sorafenib Treatment
J Clin Res Pediatr Endocrinol. 2023 Nov 9. doi: 10.4274/jcrpe.galenos.2023.2023-7-13. Online ahead of print.ABSTRACTHereditary forms of Medullary thyroid carcinoma (MTC) are rare. Different phenotypes with the same mutation may be due to differences in the timing of RET activation steps, additional mutations in other regions of the gene, or the co-occurrence of germline and somatic mutations, which is an infrequent possibility. Here, we aim to present the different features and difficulties in the follow-up of three family members with the same germline mutation. A 4-year-old male patient with respiratory distress was diag...
