Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Introduction: Patients with homozygous familial hypercholesterolemia (HoFH) suffer from this disorder from birth and they have abnormally high cholesterol levels due to a disease that has autosomal dominant inheritance of genetic aberrations in the coding region for low density lipoprotein receptors (LDLR) in more than 90% of cases, other gene defect includes mutations in apolipoprotein B100 (apoB100) and proprotein convertase subtilisin/kexin type 9 (PCSK...

Background: Infants referred with elevation of capillary TSH on newborn screening are classified as having transient TSH elevation when subsequently found to have normal venous thyroid function tests off treatment with thyroxine. Causes of transient TSH elevation include neonatal sickness, prematurity and maternal thyroid antibodies. There is little information on thyroid size in such infants.Objective: To determine thyroid volume by ultrasound in infant...

Backgrounds: The prevalence of congenital malformations (CM) is higher in infants referred with capillary (c) TSH elevation on newborn screening. However, establishing the prevalence of CM ± dysmorphic syndromes in true congenital hypothyroidism (CH) requires careful distinction between true and transient CH.Objective: To determine the prevalence of CM ± dysmorphic syndromes in all infants referred with TSH elevation on newborn screening in Sco...

Background: Screening for congenital hypothyroidism (CH) has virtually eradicated the severe mental handicap associated with late or absent treatment. We have previously reported two audits of newborn screening for CH between 1979 and 2003 showing significant improvement from the first to more recent period.Objective and hypotheses: We aimed to audit the period 2004–2013 and report trends in timing of sampling, laboratory processing, delay between f...

Background: Girls with Turner syndrome (TS) are inappropriately short for their parents’ heights; measured parental height is therefore useful in diagnosis.Objective and hypotheses: To examine the sensitivity of measured parental height in the diagnosis of TS; and to audit the frequency of parental height measurement in our clinic.Method: Case note review of all girls with TS attending our dedicated Turner clinic between 1989&...

Background: Establishing thyroid size as large, normal or small in newborn infants with TSH elevation and in situ thyroid is important for diagnosis and informing molecular genetic studies.Objective and hypotheses: To compare intra-observer variation in the objective (Ox) measurement of thyroid volume (vol) by ultrasound (US); and the correlation between subjective (Sx) and Ox assessment.Method: Joint blinded retrospective...

Background: Type 1 DM (T1DM) is a chronic condition characterized by persistent hyperglycemia; which can impair immunity and increase susceptibility to infections. Latent TB infection (LTBI) is a subclinical infection caused by Myobactaeria tuberculosis antigens without clinical, bacteriological or radiological evidence of manifest TB disease. Tuberculin test (TST) is an inexpensive test used to identify LTBI status, but has limitations. False positive TST can...

Background: Data on the neuroradiological findings in Noonan syndrome (NS) are limited.Study Design and participants: Multicentric retrospective observational study conducted in 9 Italian centers of Pediatric Endocrinology. Population includes 112 patients (62 males, 50 females; 73 PTPN11, 8 KRAS, 8 SOS1, 4 LZTR1, 4 RIT1, 4 SHOC2, 3 BRAF, 2 RAF1, 1 ERF, 1 HRAS, 1 MAP2K1, 1 MEK1, 1 PPP1CB, 1 RASA1) with diagnosis of NS ge...

Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...
