Background: Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease seen in children. The systemic features of JIA are mediated by cytokine products of an activated immune system. Recent studies showed that the median level of urine cortisol in active JIA patients is significantly lower than remission period and control groups.Objective and hypotheses: One of the najor drugs in JIA is TNFα blocker (Enbrel). The aim of the study was ...

Introduction: Growth hormone (GH) deficiency is diagnosed through the combination of clinical observation and low GH upon stimulation, in two separate stimulation tests. Normal response is considered as a single rise of GH above the local cutoff point which is used, and differs between countries and range between 7–10 mcg/L. The aim of our study was to assess whether a calculation of area under the curve (AUC) of GH can be used as an additional tool in the diagnosis of GH...

Background: The age at weaning programs life history adaptively. Shorter infancy resulted in longer/thinner animals with a reproductive-strategic shift to earlier physical and sexual development (BMC Med, 2013).Hypotheses: The length of infancy impacts also the stress-response and has behavioural consequences.Method: Sprague-Dawley pups (generation F1), which usually are weaned at age 21 days, were weaned by cross-fostering at age ...

Background: Pubertal assessment is based on patient history, physical examination, bone age, blood tests, and in some cases, endocrine “stimulation tests”. Sex hormones are present in saliva and may serve as a cost-effective, simple, and painless alternative for invasive blood or stimulation tests performed at day care units. Previous studies showed correlation between saliva-and-blood levels of sex hormones; However, it is not in routine clinical ...

Shox gene deficiency which causes short stature is a known indication for treatment with growth hormone. The prevalence of shox deficiency among children with idiopathic short stature has a high variability in different studies and ranges between 1.5-17%. We aimed to determine the incidence of SHOX haploinsufficiency in our region and to assess the genotype-phenotype relation which may help with setting criteria in the decision to which patients should we offer this genetic te...

Background: Congenital hypothyroidism is a common condition with reported incidence between 1/2000 – 1/4000 live births. In approximately 85% of cases this is sporadic due to a structural abnormality of the thyroid gland. Approximately 15% of cases are hereditary and secondary to thyroid dyshormonogenesis. Most of these are due to mutations in one of the genes involved in iodine transport or organification, mutations in the thyroglobulin gene or d...

Background: U.V. radiation exposure is the major environmental risk factor for skin cancers. However, sun avoidance leads to inadequate vitamin D levels which impair bone health. Moreover, numerous studies linked decreased sunlight exposure to non-skin cancer incidence or survival.Objective and hypotheses: To compare sun habits in a cohort of paediatric patients with a history of malignancy to healthy controls. We hypothesized that sun exposure will be d...

Background: Fasting during Ramadan, starting daily before sunrise and ending at sunset, with traditional rich meals at "Sohoor" (pre-dawn) and "Fotoor" (evening break of fast). is common among Muslims from 8 years of age. Recent use of the closed loop automated insulin delivery system (CLAIDS) including insulin pump and glucose sensor has become staple treatment of type 1 diabetes (T1D) patients and reported to safely manage glucose fluctua...

Introduction: Primary ovarian Insufficiency (POI) occurring in youth is a devastating condition. POI is characterized by at least 4 months of disordered menses in association with menopausal follicle stimulating hormone (FSH) levels. The most common causes of POI in adolescence are iatrogenic and chromosomal abnormalities. Data are scarce regarding the incidence of POI in adolescents.Objectives: We aimed to estimate the incidence and the distribution of ...

Background: T1DM incidence in children varies across regions and countries, showing a continue rise Worldwide.Objective and hypotheses: To determine the incidence of T1D in Chilean children under 20 years between 2006 and 2012.Method: We reviewed mandatory notifications of T1D (GES Program) in Chile’s public health system in population younger than 20 years between 2006 and 2014. Data were obtained from the Department of Infor...
