ated with the height standard deviation score (r=0.255; p less then 0.05), but was not correlated with serum MKRN3 level or the others. Conclusion Although serum NPTX1 level was independent of serum MKRN3 level, the possibility they might be involved in the progression of puberty or CPP remains. Further research is needed to determine their role in the hypothalamus.

Hyperammonemia in a newborn is a serious condition, which requires prompt intervention as it can lead to severe neurological impairment and death if left untreated. The most common causes of hyperammonemia in a newborn are acute liver failure and inherited metabolic disorders. Several mitochondrial disorders have been described as a cause of severe neonatal hyperammonemia.

Here we describe a new case of adenosine-triphosphate (ATP) synthase deficiency due to m.8528T>C mutation as a novel cause of severe neonatal hyperammonemia. So far six patients with this mutation have been described but none of them was reported to need hemodialysis in the first days of life.

This broadens the so far known differential diagnosis of severe neonatal hyperammonemia requiring hemodialysis.

The purpose of this study was to evaluate the impact of recombinant human growth hormone (rhGH) on the development and progression of scoliosis in patients with idiopathic short stature (ISS).

Patients with ISS who underwent rhGH treatment from 1997 to 2017 and were followed up for scoliosis screening with serial radiographic examination were included. For assessing scoliosis development, patients who did not have scoliosis at the time of rhGH treatment were included and followed up to determine whether

scoliosis developed during the treatment. For evaluating scoliosis progression, patients who already had scoliosis were analyzed. Univariate and multivariate Cox regression analyses of demographic and radiographic variables were performed to determine the related factors in the development and progression of scoliosis.

For assessing scoliosis development, 1093 patients were included. The average duration of rhGH treatment was about 2 years. De novo scoliosis developed in 32 patients (3.7%). The analysis revealed that sex (p=0.016) and chronological age (p=0.048) were statistically significant factors associated with scoliosis development. However, no relationship was observed between scoliosis development and rhGH treatment types or duration. Among 67 patients who already had scoliosis at the time of rhGH treatment, 11 (16.4%) showed scoliosis progression. However, the rhGH types and duration also did not affect scoliosis progression.

De novo scoliosis developed in 3.7% and scoliosis progressed in 16.4% of the patients during rhGH treatment. However, scoliosis development or progression was not affected by the types or duration of rhGH treatment in patients with ISS.

Thyroid cancer is the most common pediatric endocrine neoplasm representing 3% of all malignancies in children. Hashimoto’s thyroiditis (HT) is also a common disorder in the pediatric age range. Patients with HT frequently develop enlarged thyroid with nodules. We aimed to provide a literature review on the frequency of papillary thyroid carcinoma (PTC) in patients with HT.

A literature search of the PubMed database between 2000 and 2020 was performed, using the relevant keywords “papillary thyroid carcinoma,” “Hashimoto’s thyroiditis” and “children”. We followed the PRISMA statement guidelines during the preparation of this review. Six studies (n=2,065 patients with HT) were retained for the final analysis. The follow-up of the patients with HT was from 2 to 10 years. PTC was diagnosed in 0.67-7.87% of the HT patients included in these studies. In patients with HT and nodules, the percentage of PTC varied between 5.13 and 35%. selleck chemicals The overall occurrence of PTC in patients with HT was 3.07%.

The number of patients developing thyroid nodules in relation to HT was increased. The development of PTC in children with HT appeared to be higher than in the normal population.

Clinical and laboratory data of reset osmostat (RO) and cerebral/renal salt wasting (C/RSW) mimic syndrome of inappropriate antidiuretic hormone (SIADH) and can pose diagnostic challenges because of significant overlapping between clinical and laboratory findings. Failure to correctly diagnose hyponatremia may result inincreased mortality risk, longer hospital stay, and is cost-effective. We aim to illustrate clinical and laboratory similarities and difference among patients with hyponatremic disorders and discuss the diagnostic value of factional uprate excretion (FEurate) to differentiate SIADH from RO and C/RSW.

We report the use of FEurate in the evaluation of three patients with hyponatremia and elevated urine osmolality in the absence of edema or clinical evidence of dehydration to differentiate SIADH from RO and C/RSW.

Measurement of FEurate may offset in part the diagnostic confusion imparted by the diagnoses of SIADH, RO, and C/RSW.

Determine the intake and percentage of adequacy of macronutrients and their association with cardiovascular risk factors in a sample of Colombian schoolchildren.

Cross-sectional study nested in a prospective population-based cohort in schoolchildren between 6 and10 years of age; cardiovascular risk markers and anthropometric measures were measured. Macronutrient intake was established through a food consumption frequency questionnaire (FFQ). The percentage of adequacy was evaluated by comparison with the dietary reference intakes (DRI) and the recommendations for energy and nutrient intake (RIEN) for the Colombian population. Linear regression analysis was performed to assess the association between daily macronutrient/energy intake and cardiometabolic risk factors.

A total of 1,282 school children (51.09% boys and 48.91% girls; mean age 8.4±1.4 years). The percentage of energy adequacy was 107% (Q1=87.5; Q3=127.2). The macronutrients in overadequacy were proteins and carbohydrates. The total fiber had a low adequacy around 26.
